In the Washington, DC, Northern Virginia, and Maryland metropolitan area, grass pollinates mostly from the end of April through the end of August.  The peak grass pollen levels tend to be from May through July, however.  Grass is a very common allergen as it affects millions of individuals.

There are thousands of types (i.e., species) of grasses and many cross-react with one another.  This means that if you are allergic to a particular type of grass, then you are likely to exhibit allergic symptoms if you are exposed to another type of grass if it is within the same grass subfamily.  Pooideae is the largest subfamily of the grass family Poaceae.  These grasses are common grasses known to cause allergic rhinitis (i.e., hay fever) in sensitized individuals.  They tend to occur in temperate climates in the U.S.  Some of the grasses in this subfamily include Timothy, Red top, Sweet vernal, Orchard, Meadow fescue, Kentucky blue, and June.  They also include the common cereal grasses (e.g., rye, wheat, barley, oat).  Panicoideae, also in the grass family Poaceae, is another common grass subfamily and its’ grasses are also a common cause of allergic rhinitis.  Common grasses in this subfamily include Johnson and Bahia.  In the grass family Poaceae, subfamily Chloridoideae, the most common grass to cause allergy symptoms is Bermuda.  Bermuda grass tends to occur mostly in the southern half of the U.S. where there are warmer temperatures.

The typical allergic rhinitis symptoms that most allergic individuals suffer from may include all or some of the following:  sneezing, runny nose, nasal congestion, post-nasal drip, itchy nose, clogged ears, itchy ears, itchy eyes, watery eyes, puffy eyes, hoarseness, snoring, sinus congestion, sinus headaches, wheezing, chest tightness, shortness of breath, and coughing.  In very allergic individuals, contact with grasses may cause itchy skin and hives.  Rarely, a very grass-allergic person may develop anaphylaxis if he or she scrapes their skin on grass and it gets into the bloodstream, as is not uncommon in certain sports such as football, baseball, and soccer.

In order to manage one’s grass allergies, the following tips are recommended:

• Avoid mowing the lawn, but if you need to mow it, wear a mask.
• Remove your clothes after coming inside from outdoors. Take a shower to wash the pollen off of you as well as wash your clothes.
• Keep your lawn short, as grass pollinates when the grass is tall.
• Keep an eye on the pollen count. You check it daily by clicking Today’s Pollen Count.
• Wash your pets when they come indoors, as their fur will transport grass pollen into your home.
• Avoid hanging wet clothes outdoors to dry, as pollen will gather on the clothes.
• Keep your windows and sunroofs closed in your motor vehicles.
• Keep your doors and windows closed in your house.
• Use over the counter allergy medications such as oral antihistamines, nasal sprays, and/or eye drops, if approved by your physician.
• See a board certified allergist, like the ones at Black & Kletz Allergy, if your symptoms are not alleviated by over the counter medications.

Atopic dermatitis is a common genetically determined chronic inflammatory disorder of the skin. Eczema is a term used to describe the appearance of the skin in atopic dermatitis, as well as in other skin diseases. Though atopic dermatitis generally tends to be more severe in childhood and improve in adulthood, most people with this condition continue to have remissions and exacerbations throughout their lifetimes.

Environmental factors such as weather changes and food allergies can exacerbate the eczema and itching.  Atopic dermatitis is usually more bothersome during the winter months due to excessive dryness.  Individuals with atopic dermatitis are more likely to have sensitivities to foods and exposure to these foods can worsen their eczema.  Individuals with eczema tend to be most sensitive to the following foods:  milk, wheat, soy, peanut, egg, and seafood.

Though there is no known cure for atopic dermatitis, many treatments are available to relieve the symptoms and improve one’s quality of life.

Traditionally, management of atopic dermatitis consists of:

Very recently, two new forms of treatments for atopic dermatitis were approved by FDA.

Black & Kletz Allergy has board certified allergy and immunology specialists as well as a trained staff experienced in both the diagnosis and treatment of atopic dermatitis of varying degrees of severity.  We treat both children and adults and have 3 convenient office locations in the Washington, DC, Northern Virginia, and Maryland metropolitan area.  Black & Kletz Allergy has offices in Washington, DC, McLean, VA (Tysons Corner, VA), and Manassas, VA.  We have on-site parking at each location and the Washington, DC and McLean offices are Metro accessible.  There is a free shuttle that runs between the McLean, VA office and the Spring Hill metro station on the silver line.  Please call us if you, a family member, a friend, or a colleague suffers from eczema or atopic dermatitis and want to be evaluated and treated.  In addition to conventional therapy, we also have expertise in the newer treatment options for the treatment of eczematous dermatitis or any other allergic or immunologic disorder.  You may also click Request an Appointment and we will respond within 24 hours of the next business day.  The allergists at Black & Kletz Allergy strive to keep up with the newest allergy and asthma treatment modalities so that cutting edge medicine is always available to our greater Washington, DC community.

Most insect bites cause “local reactions” resulting in redness and/or swelling at the site of the bite which usually subsides in a few days.  However, stings by 5 different types of insects (honey bee, yellow jacket, yellow-faced hornet, white-faced hornet, and wasp) belonging to the Hymenoptera species, can cause a life-threatening “systemic reaction” (i.e., anaphylaxis) in sensitized individuals.  Approximately 5% of the population has had systemic reactions to stinging insects.

The more common symptoms of anaphylaxis may include:

• Swelling of the lips, face, throat, and/or tongue (i.e., angioedema)
• Difficulty breathing, wheezing, chest tightness, and/or coughing
• Dizziness or lightheadedness which could signify a drop in one’s blood pressure
• Abdominal cramping and/or diarrhea
• Nausea and/or vomiting
• Generalized itchiness (i.e. pruritus) and/or hives (i.e., urticaria)

Avoidance of stings by insects is not always possible and the reactions tend to get progressively more severe with each sting.  In fact, many fatalities are reported in the U.Ss every year from insect stings.

A highly effective form of treatment called venom immunotherapy (i.e., allergy shots for venoms) significantly reduces the risk of severe reactions in sensitized people.  The process involves building up tolerance by injecting gradually increasing doses of commercially made “extracts” from the insect venoms at regular intervals.  Venom immunotherapy has been credited with saving a number of lives and helps people live without fear of a serious reaction from insect stings.  Venom immunotherapy is effective in preventing a systemic reaction to further insect stings in approximately 95% of individuals that go on such treatment.

In the U.S., there are only two companies (i.e., ALK and HollisterStier) which manufacture insect venom extracts which are utilized as antigens during venom immunotherapy.  Unfortunately, since October 2016, ALK Laboratories has notified that it is unable to fill orders for Hymenoptera venom extracts due to manufacturing difficulties.  It is not known how long it will take to restore normal production and distribution.

HollisterStier has indicated that it is doing everything possible to equitably distribute the available venom and to ramp up production of the venoms to help deal with the shortage. However, it is expected that increased production will take time to reach the market.

As the demand now exceeds supply, there is a need to judiciously manage the reduced availability of commercial extracts.  The American Academy of Allergy, Asthma, and Immunology came up with guidance for allergy/immunology practices all over the country regarding the measures that are needed to mitigate the venom shortage that likely will exist for some period of time.

There are 4 strategies to be considered until the shortage eases up:

• Increasing the maintenance interval
• Decreasing the maintenance dose
• Suspending or restricting treatment in patients with the lowest risk of severe reaction to stings
• Scrupulous avoidance of wastage of extracts in mixing and administration

In the Washington, DC, Northern Virginia, and Maryland metropolitan area, the board certified allergists at Black & Kletz Allergy are striving to increase the supply of venom extracts by following the recommendations of the American Academy of Allergy, Asthma, and Immunology in order to make available the extracts to our patients according to their risk profiles.  Black & Kletz Allergy treats both adults and children for venom sensitivities and we have convenient office locations in Washington, DC, McLean, VA (Tysons Corner, VA), and Manassas, VA.  The Washington, DC and McLean, VA offices are Metro accessible and there is a free shuttle that runs between our McLean, VA office and the Spring Hill metro station on the silver line.

We encourage all our patients to call us and discuss their concerns over the venom shortage situation and we would be happy to answer any questions that may arise.  If you would like to make an appointment, please call us or alternatively, you can click Request an Appointment and we will respond within 24 hours by the next business day.

How does one distinguish whether they have a common cold or if they are bothered by allergies?  This question plagues many individuals all the time.  It may not be easy to differentiate the two maladies since the two conditions have a lot of crossover signs and symptoms.  An allergist in Northern Virginia and Washington, DC which can be found at Black & Kletz Allergy can help you in the differentiation among these two conditions.  In the Washington, DC, Northern Virginia, and Maryland metropolitan area, as well as the rest of the country, the common symptoms of both conditions may include runny nose, nasal congestion, post-nasal drip, sore throat, sneezing, sinus headaches, fatigue, snoring, and/or coughing.  In addition, asthma is often exacerbated with both allergies as well as the common cold causing wheezing, chest tightness, and/or shortness of breath and is also treated in the metro DC area by an allergist in Northern VA and/or Washington, DC.

In allergic rhinitis (i.e., hay fever), additional symptoms may also include itchy nose, itchy eyes, watery eyes, puffy eyes, dark circles under the eyes, and/or itchy throat.  When a common cold occurs, additional symptoms may include fevers, chills, achiness, and/or sweating.  One of the most telling signs that the symptoms are more consistent with allergic rhinitis (i.e., hay fever) rather than the common cold is if the signs and/or symptoms persist more than 1 week in duration.  Generally, the common cold and/or viral upper respiratory tract infection (i.e., URI), usually last 1 week or less.  Allergic rhinitis is an allergic condition that individuals suffer from generally for at least several weeks or more.  If the allergic rhinitis is seasonal, it may only occur when the pollen count is high.  For example, in the Spring in the Washington, DC metro area, the tree pollen usually pollinates typically from the end of February through mid-May and tree-allergy sufferers usually experience symptoms during that time period.  However, if a person is only allergic to a specific type of tree (e.g., birch, maple, oak), they will only exhibit symptoms when that specific tree pollen is pollinating.  Still, however, the time period is much longer than 1 week.  From May through early August, the grass pollinates in the Washington, DC area and an allergist in Northern Virginia and DC can help patients that are bothered by grass pollen.  Lastly, regarding pollen, ragweed in the DC metro area usually begins in mid-August and generally finishes pollinating after the first frost which usually occurs at the end of October.  Like the other pollens, an allergist in Northern VA, such as the ones at Black & Kletz Allergy can perform allergy testing via skin testing or by blood testing in order to determine one’s allergies.

An allergist in Northern Virginia and Washington, DC can help you determine if you have allergies, and to which allergens.  In addition, an allergist in Northern VA and/or Washington, DC can also recommend ways to prevent or minimize one’s exposure to allergens, as well as prescribe medications to combat one’s allergies.  An allergist in Northern Virginia and Washington, DC, like the ones at Black & Kletz Allergy can also place an individual on allergy shots (i.e., allergy immunotherapy, allergy injections, allergy desensitization) which help allergy patients 80 -85% of the time.  They are very effective and have been given for more than 100 years.

An allergist in Northern Virginia and Washington, DC that is board certified can be found at Black & Kletz Allergy.  We diagnose and treat both adultsand children.  We have 3 convenient offices with locations in Washington, DC, McLean, VA (Tysons Corner, VA), and Manassas, VA.  If you suffer from allergies, asthma, sinus problems, hives, the common cold and other infections, swelling episodes, and/or eczema, please call our office to schedule an appointment with an allergist in Northern VA and/or Washington, DC.  All 3 offices of Black & Kletz Allergy have on-site parking and the Washington, DC and McLean, VA offices are Metro accessible.  There is a free shuttle that runs between the McLean, VA office and the Spring Hill metro station on the silver line.  Alternatively, you can click Request an Appointment and we will respond within 24 hours by the next business day.  The allergists at Black & Kletz Allergy pride themselves in serving the greater Washington, DC area for providing high quality allergy and asthma care as we have been doing for more than 50 years.

More and more children and adults are being diagnosed with peanut allergy in the U.S. in the past few decades.  Peanut allergy was estimated to affect about 0.4% of children and 0.7% of adults in 1999.  By 2010, the prevalence increased to about 2% of all children.  Peanut allergy is the leading cause of death related to food allergies in U.S.

Until a few years ago, it was thought that delaying the introduction of allergenic foods to at-risk children reduced the likelihood of the development of food allergies.  However, a recent landmark study published in 2015 called LEAP (Learning Early About Peanut Allergy) provided evidence to the contrary. Based on the new findings, the National Institute of Allergy and Infectious Diseases amended the previous recommendations and issued new guidelines favoring early introduction of peanut products in children at risk for the development of peanut allergy.

It is known that infants diagnosed with eczema and/or allergies to eggs are at higher risk of developing peanut allergies.  These children were the focus of the new guidelines.  Though it is possible that other groups of children with a family history of food allergies and/or history of allergic reactions to other foods such as milk, soy, wheat, etc. also are more likely to develop peanut allergy, these children were not included in the current recommendations due to lack of enough evidence at this time.

Guideline 1:

In infants with no eczema or any food allergy, peanut products should be introduced in their diet in accordance with family preferences.

Guideline 2:

In infants with mild to moderate eczema with no other food allergy, peanut-containing foods should be introduced at about 6 months of age.  Other solid foods should be introduced before peanut-containing foods to ensure that the infant is developmentally ready.  These infants may have dietary peanut introduced at home, though some caregivers and healthcare providers may desire an in-office supervised feeding, evaluation, or both.

Guideline 3:

Infants with:

1. Severe eczema (defined as those with persistent and recurrent flare-ups of eczema needing prescription-strength medications)

2. Egg allergy (defined as those with a history of a reaction to egg and a positive skin prick test or a positive oral egg food challenge)

3. Both 1 and 2 above need to be tested for possible peanut allergy as follows:

1. If the blood test shows no peanut specific IgE antibody, peanut-containing foods should be introduced either at home or in a supervised setting in the doctor’s office at 4 to 6 months of age.

2. If the blood test shows elevated peanut IgE antibody, the children need prick skin testing with peanut antigen by an allergist.

A. If the skin test shows a wheal of 0 to 2 mm. in diameter, peanut-containing foods should be introduced either at home or in a supervised setting in the doctor’s office at 4 to 6 months of age.

B. If the skin test reveals a wheal of 3 to 7 mm. in diameter, a supervised in-office feeding or a graded oral food challenge with peanut should be undertaken. In the case of no adverse reaction, peanut-containing foods should be introduced in their diet.  In the case of an adverse reaction, peanut products should be strictly avoided.

C. If the skin test’s wheal diameter is 8 mm. or larger, these infants should avoid peanut products and should continue to be evaluated and managed by an allergist.

Infants, who are candidates for the introduction of peanut-containing foods at 4 to 6 months of age, should receive about 2 grams of peanut protein in the first feeding.  Subsequently, they should also be regularly fed about 6 grams of peanut protein per week, divided in 3 or more feedings.

It is hoped that this strategy will help in development of tolerance to peanut products and will substantially reduce the likelihood of the development of peanut allergy which can be very serious and even fatal.

What are dust mites ? Dust mites are microscopic bugs that are about 0.25 mm. in length. They are arachnids like spiders and scorpions and like the former, generally have 8 legs. They tend to live in pillows, mattresses, bedding, carpeting, plush toys, upholstered furniture, etc. and are responsible for allergy and asthmasymptoms in many individuals. When someone speaks of a dust allergy, they are in fact referring to dust mite allergy. Dust mites can survive in a broad range of environmental conditions but prefer warmer temperatures and places with higher humidity. They tend not to like high altitudes, but still can survive at relatively high elevations. Dust mites survive by eating organic matter such as your flaky dead skin that sloughs off of you each night while you are asleep. They also eat your hair, fingernails, fungi, bacteria, and can eat animal fur. For these reasons, dust mites tend to be most problematic in one’s bedroom. In addition, people tend to spend a lot of time in their bedrooms. A disgusting fact is that there are millions of these tiny bugs living on the average mattress.

Why are people allergic to them and what are the symptoms of dust mite allergy? People are actually allergic to the allergens in the dust mite’s fecal material. The two most common species of dust mites found in the United States are Dermatophagoides farinae and Dermatophagoides pteronyssinus. There are many dust mite allergens which are divided into groups. The allergens in Group 1 and Group 2 are generally the most bothersome to individuals. The allergens “Der f 1” and “Der p 1” are the most allergenic proteins that are produced by these two mites. When a sensitized individual inhales these proteins, as well as other dust mite proteins, allergic symptoms may occur which can cause all or some of the following symptoms: itchy eyes, watery eyes, red eyes, runny nose, nasal congestion, post-nasal drip, sneezing, sinus headaches, wheezing, cough, shortness of breath, and/or chest tightness. These symptoms can be the same symptoms as some people experience with pollen, mold, and/or pet allergies. In addition, dust mites may cause exacerbation of one’s eczema (atopic dermatitis).

What can be done to minimize one’s exposure to dust mites? It is advantageous to cover one’s pillows, mattress, and box spring with allergy-proof encasings that zipper up over the pillows, mattress, and box spring. This allows one to have a “protective” barrier in place between the dust mites and the individual’s nose which is responsible for inhaling the highly allergenic proteins of the dust mites. It is also beneficial to avoid wall-to-wall carpeting, especially in the bedroom and to get rid of plush stuffed animals in children’s bedrooms. Anything that tends to gather dust such as curtains also should be avoided. In addition, it is also beneficial to wash bedding in water that is equal to or greater than 130°F. The hot water will kill the dust mites, although dust mites will continue to reproduce and always will be present. Using a HEPA air filter is another important tool to reduce allergen exposure. Make sure to keep the humidity in the house below 50% as it has already been mentioned above that dust mites thrive in high humidity, particularly over 70% humidity. It is preferable to avoid sleeping in basements, as they tend to be damper and concrete floors also should be avoided, since they tend to increase moisture.

How is dust mite allergy diagnosed and treated? When an individual sees a board certified allergist, it is important for the allergist to take a detailed history from the patient so as to ascertain if his/her symptoms could possibly be due to dust mites. One common feature amongst people with dust mite allergies is that their symptoms can and usually are perennial in nature and not just seasonal as found often in patients with pollen allergies. It is also very common for patients with dust mite allergy to have a worsening of their symptoms in the Fall and Winter, which is usually the time that the heat gets turned on in most homes and businesses, particularly in the Washington DC, Northern Virginia, and Maryland metropolitan area. The next step in diagnosing dust mite allergy is a thorough physical examination to look for visual clues of hay fever (allergic rhinitis) and/or asthma. Allergy skin testing or allergy blood testing can be performed in order to confirm the diagnosis. Once a dust mite allergy is diagnosed, there are a few options for treatment which involve a combination of reducing one’s exposure to dust mites as mentioned in the previous paragraph, and medical treatment. Treatment can be given to patients by either using medications and/or receiving allergy immunotherapy (i.e., allergy shots, allergy desensitization). Allergy medications may include antihistamines, decongestants, nasal sprays, and/or eye drops, etc. Allergy desensitization has been around for over a century and has been proven to be very effective to treat dust mite allergies, as well as pollen, mold, pet, insect sting hypersensitivity, etc.

About 220 million doses of vaccines are distributed in the United States each year. Mild swelling and redness at the site of the injections and fever lasting for 1 to 2 days are very common reactions after vaccinations.  These adverse reactions do not preclude receiving future doses of the vaccines.  Rarely, however, sensitivity to a vaccine constituent may cause a lump at the injection site several hours after its administration, and this is also not a contraindication to subsequent vaccination.  In cases of severe adverse reactions, on the other hand, it is prudent to avoid further vaccination with that particular vaccine.  In these cases, a board certified allergist may measure the levels of IgG antibodies to the immunizing agent(s) to detect whether the individual has the sufficient amount of protective antibody levels.  Depending on the levels, the allergist can help determine whether further doses are needed.  If needed, the allergy doctor will discuss the risks of re-vaccination and may desensitize the individual to a particular vaccine, if the ability exists for that immunizing agent.

In cases of an anaphylactic reaction (a severe life-threating reaction involving multiple organ systems) to a vaccine, further evaluation should be undertaken by an allergist in an attempt to identify the culprit allergen.  These types of reactions are more often caused by additives (e.g., preservatives) or residual vaccine components, such as gelatin, rather than the microbial immunizing agent itself.

Patients who experience an apparent anaphylactic reaction should undergo immediate-type allergy skin testing to confirm that the reactions were mediated by an IgE antibody and to determine the responsible component of the vaccine.  If the skin tests are negative, the chance that the patient has IgE antibodies to any vaccine component are negligible, and the vaccine can usually be administered under physician supervision with epinephrine and other medications readily available.  If the skin tests are positive and suggestive of an IgE-mediated reaction, consideration may be given to administer all future doses in a graded fashion under close physician monitoring.

Pregnant women should not receive live vaccines.  They can however be given inactivated influenza (i.e., “the flu”), tetanus, and hepatitis B vaccines, if approved by their Obstetrician.  Live vaccines should also not be given to persons with immune system defects and/or function because of a risk of it resulting in a generalized infection with that immunizing agent or vaccine.

Certain vaccinations (e.g., MMR) and/or the preservatives used in some vaccines (e.g., thimerosal) have been purported to have long-term consequences such as autism.  Other vaccines (e.g., hepatitis B, influenza, tetanus) have been alleged to cause or aggravate multiple sclerosis.  Epidemiological studies have not supported such associations at this time, so it is probably safe to say that it is very unlikely that the MMR vaccine or thimerosal causes autism.  Likewise it is also fair to say that at this time in is very unlikely that the hepatitis B vaccine causes multiple sclerosis or that the hepatitis B, influenza, and/or tetanus vaccines worsen a patient’s multiple sclerosis.  It is however very important to discuss such apprehensions with your physician before receiving a vaccination, as you are your best advocate.

Individuals with a history of a suspected egg allergy should be evaluated by an allergist to determine the status of their egg allergy.  Most people, even with confirmed egg allergy, should receive influenza vaccinations because the risks of vaccinating are generally outweighed by the risks of not vaccinating.  Skin testing with the influenza vaccine is no longer recommended in people with a history of an allergic reaction to eggs.

Patients with egg allergy with a history of only hives after egg ingestion can receive the influenza vaccine in a primary care provider’s office provided the appropriate personnel and equipment are available, whereas those with a history of more severe reactions to egg ingestion should receive their vaccine in an allergist’s office.

In patients with a history of an allergic reaction to the influenza vaccine itself, additional evaluation is appropriate including skin testing with the vaccine and vaccine ingredients.  For patients with positive skin test results, the vaccine can either be administered in multiple divided doses (i.e., desensitization) or it can be withheld.

Most people are aware of many of the typical allergies that a lot of individuals suffer from, but did you know that there are many unusual allergies that are kind of common?  Some of the classic allergies or allergic conditions that most people have heard about include hay fever (i.e., allergic rhinitis), food allergies, medication allergies, insect sting allergies, asthma, hives (i.e., urticaria), and eczema.  There are however some unfamiliar allergies that exist that one may want to be aware of, as they are not uncommon.

Allergy to Vibration

The medical term for this allergy is vibratory urticaria.  Individuals with this condition develop hives on the skin where they have been exposed to vibration or repetitive stimulation.  Individuals who work with jackhammers may develop hives on their hands.  People who mow the lawn may get hives on their hands or if they use a riding lawn mower, they may also develop hives on any part of their body that vibrates.  Hand clapping and drying oneself with a towel are also common causes.  The hives may be accompanied by itching, swelling, and/or local redness.  They generally occur within 10 minutes after stimulation of the skin and typically last less than 2 hours, although more severe reactions are known to occur.  Treatment is based on prevention, antihistamines, and other medications.

Allergy to Kissing

This actually is usually due to the person being allergic to a medication, cosmetic, and/or specific food such as peanuts, tree nuts, fish, and shellfish, although any food can cause this condition.  There are reported cases of allergic individuals that have kissed another person who had recently eaten a food that the allergic individual was allergic to resulting in an allergic reaction in the allergic individual.  The allergic reaction can be mild (e.g., itchy lips, itchy mouth, rash on lips, rash in mouth), moderate, or severe (e.g., hives, wheezing, shortness of breath, throat swelling, anaphylaxis), which can be life-threatening.  In fact, there have been fatalities documented.  Understanding what allergies you have is the first step to preventing this type of unwanted allergic reaction.

Allergy to the Sun

Often referred to as solar urticaria, this condition and is characterized by itching, burning, and hives in sun-exposed areas of the body.  In some individuals, they can occur on parts of the body that are covered by thin light clothing.  The symptoms usually occur within a half-hour of sun exposure and usually lasts for a few hours after there is no more sun exposure.  The disorder can occur from natural sunlight or artificial lighting.  Treatment generally involves avoiding sunlight, antihistamines, Xolair (i.e., omalizumab) injections, and/or UV light treatments.

Allergy to Money

This may sound made up, but it is not uncommon for some individuals to develop rashes on their hands which usually begins about 24-48 hours after handling coins.  The rashes can consist of blisters, redness, and/or dry skin and be accompanied by itching.  The nickel in the coins is usually the culprit and nickel allergy is a fairly common cause of this contact dermatitis.  People who handle money often such as cashiers and bank tellers, as well as jewelers (i.e., jewelry often contains traces of nickel) are more prone to this condition.  People with this condition may also be bothered when they eat foods that are high in nickel (i.e., cocoa, soybeans, kidney beans, cashews, spinach).  In addition to avoiding nickel, the treatment may include antihistamines, moisturizing creams, corticosteroid creams, and oral corticosteroids.

Allergy to Exercise

If you don’t feel like exercising, you may have a legitimate reason why.  Exercise may cause many symptoms that are found in other allergic conditions.  Exercise in some individuals may be a trigger and cause that individual to wheeze, become short of breath, develop chest tightness, and/or cough.  This is often referred to exercise-induced asthma.  In others, exercise may trigger generalized itching (i.e., pruritus), hives, swelling (i.e., angioedema), and/or anaphylaxis.  These symptoms generally occur within minutes of completion of an exercise routine, but can occur during exercise itself.  The symptoms generally subside within 3 hours.  In a more unusual and rare condition, there is a condition where an individual will develop any of the above symptoms if they eat a certain food within 2 hours of exercising.  These individuals can exercise without problems and they can eat that certain food without problems, but if they consume that food and exercise within 2 hours, the allergy or asthma symptoms occur.  The foods most commonly associated with this condition include celery, shellfish, wheat, nuts, legumes, and seeds, although any food can trigger this condition referred to as “food-dependent exercise-induced” asthma, pruritus, urticarial, angioedema, and/or anaphylaxis.

The board certified allergists at Black & Kletz Allergy have treated numerous patients with all of the above conditions in the Washington, DC, Northern Virginia, and Maryland metropolitan area for more than 50 years.  We treat both adults and children and we have offices in Washington, DC, McLean, VA (Tysons Corner, VA), and Manassas, VA.  All 3 offices of Black & Kletz Allergy have on-site parking and the Washington, DC and McLean, VA offices are Metro accessible.  There is a free shuttle that runs between our McLean, VA office and the Spring Hill metro station on the silver line.  If you would like to be seen for hay fever, asthma, hives, swelling episodes, generalized itching, eczema, insect sting allergies, food allergies, medication allergies, or any other allergy or immunologic condition, please call us to make an appointment or alternatively, you can click Request an Appointment and we will respond to you within 24 hours of the next business day.  Black & Kletz Allergy is proud to continue to provide high quality allergy and asthma care to the Washington, DC metropolitan area.

What is it?

Latex is a milky sap produced by the rubber trees.  It is combined with several chemicals in the manufacturing process to give latex its elastic characteristic.

Where is it found?

Natural rubber latex is used to make many common consumer products including balloons, toys, tires, elastic clothing waistbands, erasers, rubber bands, baby bottles, nipples used on baby bottles, pacifiers, athletic shoes, soles of shoes, condoms, etc.  It is also utilized in the manufacturing of many medical and dental devices such as gloves, dental dams, airway and IV tubing, stethoscopes, and catheters.  Synthetic rubber products (e.g., house paint) are not made with natural latex.

What causes allergies?

The immune system sees the protein in latex as a foreign invader.  To help protect us from foreign aggressors, the immune system mounts a defensive attack against the allergenic proteins found in natural rubber latex by making antibodies (i.e., immunoglobulins) to fight it. When we are exposed to latex products, these antibodies attack the proteins in the latex, releasing chemical mediators into the bloodstream (e.g., histamine, leukotrienes) which are responsible for the symptoms during allergic reactions.

Who is at risk?

• Health care workers and others who wear latex gloves. Natural rubber proteins can attach to the cornstarch powder used in latex gloves and can become airborne and cause reactions through inhalation.
• People who have had multiple surgeries, such as children with spinal defects.
• Rubber industry workers

What are the symptoms?

• Itching (i.e., pruritus), rash, and/or hives (i.e., urticaria)
• Nasal congestion, runny nose, and/or itchy nose
• Wheezing, shortness of breath, chest tightness, and/or coughing
• Swelling (i.e., angioedema) of parts of the body such as the throat, lips, eyes, and tongue.
• Nausea and/or dizziness
• Anaphylaxis, a severe life-threatening reaction manifested by a multiple organ system allergic reaction which may include a drop in blood pressure, breathing difficulty, generalized itching, hives, swelling, and/or abdominal cramping, as well as other symptoms.

The above symptoms usually begin within a few minutes after latex exposure and are categorized as an immediate hypersensitivity reaction.  The reactions usually occur only after a number of exposures, but the severity of reactions can worsen with repeated exposures.

Physical contact with latex can also cause soreness and blistering of the skin which usually begins 2 to 3 days of exposure.  This type of reaction is called allergic contact dermatitis.  It is similar to the reaction that is caused by poison ivy, poison oak, and poison sumac, which is referred to as a delayed-type hypersensitivity reaction.

Are foods a problem?

People who are sensitive to latex can also adversely react to certain fruits and vegetables such as apples, avocados, bananas, chestnuts, carrots, celery, kiwi, melons, papayas, potatoes, and tomatoes due to the sharing of similar proteins (i.e., cross-reactivity).

How is the condition diagnosed?

When the history is suggestive of a latex allergy, a blood test can be done to confirm the diagnosis.  Furthermore, allergy skin testing can also be done in individuals who have a negative blood test but the index of suspicion for a latex allergy is high.

What treatments are available?

As one cannot be desensitized to latex, avoidance of latex exposure (both contact and inhalation) is the only way to protect individuals from untoward reactions.

• Health care workers should wear synthetic and non-powdered gloves which do not contain natural rubber products.
• Patients with a history of previous reactions should be exposed only to non-latex medical products and devices and operated upon only in non-latex environments.
• The latex-allergic individual should wear a medical alert bracelet, so that people are aware of their allergy.
• The latex-allergic person should always carry an EpiPen, Auvi-Q, and/or Adrenaclick self-injectable device for emergency treatment and know to then go immediately to the closest emergency room.

Now that it is Winter and the temperatures are cold, one may think that they do not have anything to worry about when it comes to allergies and asthma in the Washington, DC metropolitan area like in the cities of McLean, VA (Tysons Corner, VA), and Manassas, VA.  Unfortunately, this is not true, as the cold weather can mimic allergies in many individuals and produce the same symptoms that occur in allergic people.  In addition, during the Winter, there are many allergens that still exist (i.e., dust mites, molds, pet dander and saliva, cockroaches, rodents) which cause allergic and asthmatic symptoms in susceptible individuals.  Furthermore, there are a lot of viruses that are prevalent in the Winter that can also cause symptoms that can be confused with allergies.  These viruses are also responsible for upper respiratory tract infections (URI’s) that are known to exacerbate asthma in many asthmatics.

It is well known that cold air can cause a runny nose and watery eyes.  The runny nose is a result of the vascular constriction caused by the cold air.  Non-allergic individuals that have these symptoms may think they have allergies.  Allergic individuals that have these symptoms may truly be having these symptoms because of the vascular constriction or because they are at increased exposure to allergens found during the Winters such as dust mites, molds, pet dander and saliva, cockroaches, and rodents.  Cold air is also a very well know trigger in many asthmatics and in these patients can cause wheezing, shortness of breath, chest tightness, and/or coughing. Exercising in the cold air is another important trigger for many asthmatics.

During the Winters in the Washington, DC, Northern Virginia, and Maryland metropolitan area, it is common for people to contract a multitude of viruses that cause upper respiratory tract infections.  The most common viruses that are responsible for URI’s include the rhinovirus, influenza virus (i.e., flu), parainfluenza virus, coronavirus, respiratory syncytial virus (i.e., RSV), picornavirus, adenovirus, coxsackievirus, and echovirus.  URI’s cause many symptoms that are the same as allergic rhinitis symptoms such as nasal congestion, runny nose, sneezing, sinus headaches, clogged ears, cough, and fatigue.  In addition, URI’s are known to exacerbate asthma in many asthmatics.

Three other conditions that the cold can cause that can be misconstrued as an allergy include hives (i.e., urticaria), swelling episodes (i.e., angioedema), and generalized itching (i.e., pruritus).  These skin conditions can be caused by exposure to cold air or cold water. There a many factors that can cause hives, swelling episodes, and/or itching; some of which include medication allergies, food allergies, certain infectious diseases, autoimmune disorders, and thyroid abnormalities.  In the Winter in the Washington, DC metro area, one must also think of the cold weather as a cause of these skin conditions.

The board certified allergists at Black & Kletz Allergy have more than 50 years of experience in diagnosing and treating allergies, asthma, hives, swelling episodes, generalized itching, URI’s (including sinus infections and bronchitis) in both adults and children. Whether they are caused by the cold or caused by other factors, Black & Kletz Allergy has the experience and expertise in treating these conditions.  We have offices in Washington, DC, McLean, VA (Tysons Corner, VA), and Manassas, VA and offer on-site parking at all locations.  The Washington, DC and McLean, VA offices are Metro accessible and we provide a free shuttle that runs between our McLean, VA office and the Spring Hill metro station on the silver line.  To schedule an appointment, please call us or alternatively, you can click Request an Appointment and we will respond within 24 hours by the next business day.  Black & Kletz Allergy is proud to provide high quality allergy care to the Washington, DC, Northern Virginia, and Maryland metropolitan area residents in a friendly and professional setting.

The onset of winter in the Washington, DC, Northern Virginia, and Maryland metropolitan area brings with it an increase in the frequency of respiratory infections. In comparison to individuals without an underlying long-term health condition, people with a history of allergies, asthma, diabetes, as well as individuals with suppressed immune systems are more susceptible to respiratory tract infections.

Some common respiratory infections during the Winter include:

Sinus infections (acute rhinosinusitis): According to Centers for Disease Control and Prevention, about 1 in 8 adults are diagnosed with sinus infections yearly, resulting in more than 30 million diagnoses in the U.S. More than 90% of these cases are viral. Antibiotics are not guaranteed to be of any benefit, even when they are caused by bacteria.

Bacterial cause is more likely when the symptoms are:

Management:

Bronchitis:

Inflammation of the lining of the bronchial tubes that carry air in and out of the lungs causes a cough lasting several days or weeks.

Medications for relief of symptoms may include:

Non-specific upper respiratory tract infections (URI’s):

Most adults experience two to four URI’s (e.g., “colds”) each year. More than 200 different types of viruses are known to cause the common cold.

Prominent “cold” symptoms consist of nasal congestion, clear runny nose, post-nasal drip, sore throat, cough, fever, headache, and/or body aches.

Treatment is mostly geared towards relieving symptoms, as the condition usually resolves spontaneously after a few days to one week and antibiotics are not needed.

Decongestants combined with first-generation antihistamines may provide short-term relief of nasal symptoms and cough. Anti-inflammatory medications (e.g., ibuprofen, naproxen) can relieve fever and aches. Nasal saline irrigation can sometimes be helpful.

Pharyngitis (throat inflammation):

About 90% of throat infections are caused by viruses. Only about 5 to 10% of cases are due to bacteria which are commonly referred to as “Strep throat.”

Rapid Antigen Detection Test (RADT), also known as a “strep-test” may be necessary to distinguish between viral and bacterial pharyngitis, as the clinical features are similar in both conditions.

Antibiotics are not recommended for patients with a negative RADT result. For those with a positive RADT result, amoxicillin or penicillin VK are the drugs of choice as they are very effective against streptococcal bacteria. For penicillin-allergic patients, antibiotics in the macrolide class, as well as clindamycin, may be utilized. The duration of treatment for bacterial pharyngitis is typically 10 days.

As we enter the Winter season, while many people see an improvement in their allergy symptoms because of the lack of pollen in the air, many other individuals experience a worsening of their allergy symptoms due to the increase in the amount of perennial allergens that are present during this time of the year.  Specifically, people with sensitivities to dust mites, molds, pets, and cockroaches tend to do worse in the Fall and Winter months.  Despite the fact that all of these allergens are omnipresent in the Washington, DC, Northern Virginia, and Maryland metropolitan area, and are present year-long, during the colder months, individuals tend to “close up” their homes and workplaces more than in the Spring and Summer months.  During the Fall and Winter, people generally keep the windows shut, turn on the heat, and go outdoors less often.  These factors all play a role in increasing the exposure to more quantities of dust mite, mold, pet dander, and cockroach allergens. Hence, individuals may be bothered more in the Fall and Winter.

It is noteworthy to mention that all of the above allergens are found only indoors, except molds and occasionally pets.  When the leaves fall from the trees in the Fall and get wet, molds will grow on the decaying leaves.  In the Washington, DC metro area, the leaf mold is a major allergen that causes a great deal of suffering for many allergy patients.  When the leaves are disturbed by either raking them, rainfall, or via the wind, the mold spores are more likely to become airborne, thus increasing the likelihood of them causing allergy symptoms in individuals with mold sensitivities.  It is therefore recommended that a person with mold allergies should avoid exposure to leaves, particularly if they are or have been wet.  They should also keep the humidity of their homes below 35%, if possible as there is direct correlation with increased humidity and the amount of mold growth.  In the home, mold growth tends to be more abundant in basements, bathrooms, and kitchens due to the increased moisture found in these places.

The main culprits of dust allergy are the dust mites prevalent in the Washington, DC metropolitan area.  There are 2 very common species of dust mites in the Washington, DC, Northern Virgina, and Maryland metro area.  They are known as Dermatophagoides fariniae (i.e., American dust mite) and Dermatophagoides pteronyssinus (i.e., European dust mite).  Both species are highly allergenic and tend to live indoors in places like carpeting, upholstered furniture, pillows, mattresses, box springs, and bedding.  It is technically the fecal particles and exoskeleton that are the allergenic components of the dust mites.  The dust mites are microscopic and look similar to a cockroach, however, they cannot be seen with the naked eye.  They are about 0.25 mm. in length.  They survive by eating dead skin that regularly sloughs off of humans each night.  The dust mites thrive in warm moist climates and when the humidity is high.  They do not survive if the temperature is over 130° F or when the altitude is greater than 1 mile (5,280 feet).  Dust mites are known to be a cause of allergic rhinitis and asthma in many individuals.  There are products that can be put on carpeting that act to kill dust mites, but these products have been shown not to very effective.  Encasing one’s pillows, mattresses, and box springs in allergy-proof encasings are a fairly effective way to minimize exposure to dust mites.

When the home is “closed up,” pet allergens from the dander and saliva tend to be worse.  Usually, however, pet allergy tends to be very similar for most individuals despite the time off the year.  Likewise cockroach allergy is common particularly in major cities such as Washington, DC.  Many homes, apartments, condos, restaurants, and public buildings in urban settings are infested with cockroaches, even though they may not be visible during the day to most people.  It is important to make sure that traces of food are not left on counters, floors, etc., as this attracts cockroaches.  There is a common strong association between cockroach allergy and childhood asthma in inner city populations.  Cockroaches are potent allergens allergy sufferers of all ages and cause both allergic rhinitis and asthma symptoms.

Other than avoidance, which is always preferable, there are numerous medications that can be used by allergists to treat dust mite, mold, pet, and cockroach allergies.  Allergy shots (i.e., allergy injections, allergy immunotherapy, allergy desensitization) are a very effective tool that board certified allergists use to treat individuals with these allergies, as well as pollen allergies.  They work in 80-85% of people and allergy injections have been used in the U.S. for over 100 years.  The average length of treatment is 3-5 years.

Aspirin-Exacerbated Respiratory Disease (AERD) is an acquired condition in which the sensitivity to aspirin and/or related drugs (e.g., nonsteroidal anti-inflammatory drugs or NSAID’s) is associated with long term inflammation of the upper and lower airways.

How common is AERD? Approximately 8% of the adults in the U.S. are asthmatics and 9% of those individuals have AERD. About 13% of U.S. adults have chronic nasal and/or sinus disease and 15% of those have AERD.

AERD is a clinical syndrome consisting of: 1. Growth of polyps inside the nose 2. Chronic sinus inflammation and/or recurrent sinus infections 3. Persistent asthma, which is often difficult to control 4. Allergic sensitization to aspirin and/or other nonsteroidal anti-inflammatory drugs (NSAID’s)

What causes AERD? Although the exact cause remains unknown, a disorder in the metabolism or breakdown of a chemical called arachidonic acid is at the root of the condition. Aspirin is not the cause of the disorder, but in sensitive individuals, ingestion of aspirin will aggravate the underlying respiratory symptoms, probably by increasing the levels of inflammatory chemical mediators called leukotrienes. This process also leads to the accumulation of excessive numbers of eosinophils (i.e., “the allergy white blood cell”) in the respiratory tract.

Clinical Features: 1. Severe nasal congestion 2. Overgrowth of polyps in the nose, which typically recur after surgical removal 3. Decreased sense of taste and/or smell 4. Facial pressure and pain 5. Frequent headaches 6. Moderate to severe asthma causing wheezing, coughing, chest tightness and/or shortness of breath 7. Fatigue caused by sleep deprivation 8. Significant opacification of the sinuses seen in X-rays and CT scans of the sinuses

Diagnosis: The diagnosis is suspected when there is a history of an exacerbation of one’s asthma following ingestion of aspirin and/or NSAID’s. The diagnosis is confirmed if the symptoms are induced or aggravated during an oral aspirin challenge, where incremental doses of aspirin are administered by mouth under the close monitoring by a board certified allergist.

Treatment Options: Complete avoidance of aspirin and other salicylates (e.g.,diflunisal (Dolobid); salsalate (Disalcid), as well as other related NSAID medications called COX-1 inhibitors (e.g., all NSAID’s except celecoxib) will help some patients attain better control of their symptoms. For some individuals, however, these medications can be substituted for other similar NSAID pain relievers called COX-2 inhibitors without adverse effects. Note that Celebrex (celecoxib) is currently the only approved COX-2 inhibitor NSAID in the U.S. Some, but not all, of the common available NSAID’s which are COX-1 inhibitors include . Avoidance of aspirin is not always possible due to the need for aspirin in the management of heart, blood vessel, and joint diseases. In addition, even with the avoidance of aspirin and NSAID’s, AERD patients usually experience progressive airways disease, despite aggressive surgical intervention and/or topical or systemic anti-inflammatory treatment with corticosteroids and leukotriene antagonists like montelukast (Singulair), zafirlukast (Accolate), and zileutin (Zyflo).

For these individuals that need to be treated with aspirin, aspirin desensitization followed by regular long term intake of aspirin is an alternative option. Multiple studies have shown that desensitization and daily treatment with aspirin can significantly improve overall symptoms and quality of life, decrease formation of nasal polyps and sinus infections, reduce the need for oral corticosteroids and sinus surgery, and improve nasal and asthma scores in patient with AERD. Significant clinical improvement is seen in as little as 4 weeks after treatment.

The procedure for aspirin desensitization involves administering aspirin by mouth in gradually increasing doses at regular intervals, while closely monitoring for adverse effects in a controlled setting such as an allergy office. The process can take 1 to 2 days. There is a potential for adverse reactions during the procedure like nasal congestion, generalized itching (pruritus), hives (urticaria), swelling of the soft tissues (angioedema), wheezing, breathing difficulty, drop of blood pressure, and/or anaphylaxis. In case of a minor adverse reaction, they may be treated with medications. After observation for about 3 hours, the last dose can be repeated. Many individuals will be able to successfully finish the procedure in spite of some untoward reactions. Pre-treatment with leukotriene antagonists (e.g., montelukast) play a role in minimizing the risk of reactions during the desensitization procedure.

Aspirin desensitization reduces nasal congestion and nasal polyp formation, improves respiratory symptoms, reduces the need for surgery, and decreases the need for ongoing medications. The board certified allergists at Black & Kletz Allergy have had over 50 years of experience with patients who have aspirin sensitivity. Desensitization in patients who are sensitive to aspirin can be done in any of our 3 office locations in the Washington, DC, Northern Virginia, and Maryland metropolitan area.
