What is Latex Allergy?

Latex allergy, also known as natural rubber latex (NRL) allergy, is an immune system reaction to certain proteins found in the milky sap of the Hevea brasiliensis rubber tree. This reaction can cause a range of symptoms, from mild skin irritation to life-threatening allergic reactions.

Symptoms of Latex Allergy

The common symptoms of latex allergy include:

• Tingling in the mouth
• Stuffy nose
• Itchy eyes
• Wheezing
• Skin rash
• Hives
• Flushing
• Itching
• Nasal, eye, or sinus symptoms
• Asthma
• Rarely, shock

Types of Reactions

There are two main types of reactions to latex: immediate allergic reactions and irritant dermatitis. Immediate allergic reactions are rare and can cause severe symptoms, while irritant dermatitis is more common and causes rough, dry, and scaly skin.

Latex Allergy Symptoms

A latex allergy can cause a range of symptoms, from mild to severe. Here are some common signs and symptoms:

• Mild symptoms: Itchy eyes, runny nose, itchy back of the throat, irritated skin
• Severe symptoms: Skin rashes, blisters, anaphylaxis (a life-threatening allergic reaction)
  • Anaphylaxis can cause: swelling of the mouth, tongue, and throat, difficulty breathing, chest tightness
• Respiratory symptoms: Wheezing or whistling sound with breathing, asthma-like symptoms
• Skin reactions: Hives or raised, itchy bumps on the skin, scaling, burning, blistering (in cases of allergic contact dermatitis)
• Other symptoms: Tingling in the mouth, stuffy nose, conjunctivitis (pinkeye), cramps

Symptoms can vary from person to person

It's essential to note that symptoms can range from mild to severe and may not always be immediately apparent. If you experience any of these symptoms after exposure to latex-containing products, seek medical attention promptly.

Diagnostic Tests for Latex Allergy

There are several diagnostic tests used to determine if someone has a latex allergy. These tests can help identify the presence of specific IgE antibodies produced in response to latex allergens.

• Percutaneous (prick) skin test: This is one of the most common methods used to identify specific IgE antibody. It involves placing a small amount of latex on the skin and observing for any reaction.
• Radioallergosorbent test (RAST): This test measures the presence of IgE antibodies in the blood that are produced in response to latex allergens. The results can indicate the level of sensitivity and specificity of the test.
• Challenge test: This is a more invasive test where a small amount of latex is introduced into the body, and the reaction is observed.

According to [5], the percutaneous (prick) skin test and RAST are the two most common methods used to identify specific IgE antibody. The Latex Allergy Test measures immunoglobulin E (IgE) antibodies produced in response to latex allergens, indicating the presence of lgE [6].

It's worth noting that skin testing is not used for the diagnosis of latex allergy and has not been approved by the U.S. Food and Drug Administration [7]. A positive latex RAST and/or skin prick test or challenge test to NRL can confirm a latex allergy diagnosis [8].

Treatment Options for Latex Allergy

Latex allergy can be effectively managed through various treatment options, which include:

• Antihistamines: Antihistamines are a standard treatment for latex allergy symptoms [3]. They work by blocking the action of histamine, a chemical released by the body in response to an allergic reaction. Non-drowsy antihistamines like loratadine (Claritin) can be taken to help treat mild symptoms [7].
• Corticosteroid medicines: Corticosteroids are another treatment option for latex allergy. They can be used to reduce inflammation and swelling caused by the allergy [2].
• Soothing lotions: Soothing lotions like calamine or a 1% hydrocortisone cream can also be used to help alleviate symptoms [2].

Severe Allergic Reactions

In cases of severe allergic reactions, injectable epinephrine can be used to prevent anaphylaxis [4]. Epinephrine is a medication that helps to constrict blood vessels and improve breathing. It's essential for individuals with latex allergy to carry an epinephrine auto-injector (EpiPen or Auvi-Q) with them at all times.

Treatment Guidelines

The cornerstones of treatment for latex allergy are epinephrine and H1 antihistamines [5]. Systemic corticosteroids and H2 blockers may also be useful in managing symptoms. It's essential to consult an allergist for proper diagnosis and treatment.

The differential diagnosis for latex allergy involves identifying conditions that may present similarly to a latex allergy, but are actually caused by other factors. According to the American Academy of Allergy, Asthma, and Immunology [1], irritant contact dermatitis can be a common differential diagnosis for latex allergy.

Some symptoms that may be similar to those experienced in a latex allergy include:

• Pruritus (itching) of exposed skin and mucous membranes
• Edema (swelling) of the skin, mucous membranes, or subcutaneous tissues
• Hoarseness
• Tearing

In addition to irritant contact dermatitis, allergic contact dermatitis is also a differential diagnosis for latex allergy [9]. This condition occurs when the immune system reacts to an allergen in the latex, causing inflammation and other symptoms.

Other conditions that may be considered in the differential diagnosis of latex allergy include:

• Anaphylaxis: A severe, life-threatening allergic reaction that can occur within minutes of exposure to an allergen
• Rhinitis: Inflammation of the nasal passages, which can cause symptoms such as congestion, runny nose, and sneezing

According to a study by Parisi et al. [5], almost 40% of patients with latex allergy have the latex-fruit syndrome, caused by cross-reactivity with food allergens. This condition should also be considered in the differential diagnosis.

In order to accurately diagnose latex allergy, a board-certified healthcare professional, often an allergist, will typically perform a series of tests and evaluations [1]. These may include skin testing, serology testing, and provocation testing.
