Grass Allergy and What Can Be Done to Help You

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.

New Treatments for Eczema

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:

  1. Identifying the triggering and aggravating factors (which can vary from patient to patient) for eczema and avoiding exposure as best as possible.
  2. Hydrating the skin with daily application of emollients (i.e., moisturizing creams and lotions) all over the body immediately after bathing or showering.
  3. Limiting the duration of bathing or showering to a few minutes, if possible.
  4. Oral antihistamines to relieve the troublesome itching. The goal is to break the itch-scratch cycle which can perpetuate eczema.
  5. Antibiotics to reduce the colonization of the inflamed skin with bacteria, especially when there are open sores in order to prevent secondary skin infections such as staph.
  6. Topical calcineurin inhibitors [e.g., Protopic (tacrolimus) ointment and Elidel (pimecrolimus) ointment] are immunomodulators which can help in controlling inflammation of the skin. Note that this group of drugs carries an FDA “black box” warning that certain type of tumors (e.g., lymphomas) were observed in rodents receiving these medications.
  7. Corticosteroid creams and ointments are the mainstay of controlling the flare-ups of eczema due to their anti-inflammatory properties. More than a dozen varieties of topical steroids are available with varying degrees of potency.  Due to their potential side effects which can include thinning of the skin and whitish discoloration (i.e., hypopigmentation), among their use is generally restricted to 10 days to 2 weeks at a time.
  8. In severe cases of atopic dermatitis unresponsive to the usual treatments, systemic immuno-suppressants (e.g., cyclosporine, dapsone) are employed to control severe inflammation. However their use is limited by their toxicity to other organs such as the liver and kidneys.

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

  1. Eucrisa (i.e., crisaborole) belongs to a class of drugs called phosphodiesterase-4 (PDE-4) inhibitors. It is available as a 2% ointment and indicated for treatment of mild to moderate atopic dermatitis in patients 2 years of age and older.  It should be applied in a thin layer to the affected area twice a day.  Since it is not a steroid, it can be applied even to the face.
  2. Dupixent (i.e., dupilumab) is a biologic injectable medication approved for treatment of moderate to severe atopic dermatitis not adequately controlled by topical therapies in patients 18 years of age and above. It is a monoclonal antibody which blocks the receptor of a common inflammatory mediator called IL-4 (i.e., interleukin-4).  The initial dose is two injections (given subcutaneously under the skin) of 300 mg. each at different sites, followed by 300 mg. every other week.  It can be used along with or without topical steroids preparations.
