Allergic Rhinitis in Children

Overview

Allergic rhinitis, commonly known as hay fever, is an allergic reaction that occurs when a child’s immune system overreacts to allergens in the environment, such as pollen, dust mites, pet dander, or mold. These allergens trigger inflammation in the nasal passages, leading to symptoms like sneezing, runny nose, and itchy eyes. Allergic rhinitis can occur seasonally (often in response to pollen) or year-round (due to indoor allergens). While allergic rhinitis is not life-threatening, it can cause significant discomfort and affect a child’s quality of life, including sleep, school performance, and overall well-being.

Symptoms

The symptoms of allergic rhinitis are similar to those of the common cold but are triggered by allergens rather than viruses. Common symptoms include:

  • Sneezing: Frequent sneezing, especially in rapid succession.
  • Runny or stuffy nose: A clear, watery nasal discharge is common, or the nose may feel blocked due to swelling.
  • Itchy nose, throat, or eyes: Persistent itching in the nose, throat, or eyes is a hallmark of allergic rhinitis.
  • Watery, red, or swollen eyes: Also known as allergic conjunctivitis, this symptom often accompanies allergic rhinitis.
  • Post-nasal drip: Mucus dripping down the back of the throat, causing irritation and coughing.
  • Fatigue or irritability: Poor sleep due to nasal congestion can lead to tiredness and irritability during the day.
  • Nosebleeds

Causes

Allergic rhinitis occurs when the immune system identifies harmless substances in the environment, such as pollen or pet dander, as threats. This leads to the release of chemicals, such as histamine, that cause the symptoms of an allergic reaction. Common allergens that trigger allergic rhinitis include:

  • Pollen: From trees, grasses, and weeds, particularly in the spring, summer, and fall.
  • Dust mites: Microscopic organisms that live in household dust and thrive in bedding, upholstered furniture, and carpets.
  • Pet dander: Tiny flakes of skin shed by cats, dogs, and other furry animals.
  • Mold: Fungi that grow in damp indoor areas, such as bathrooms, basements, and kitchens.
  • Cockroach allergens: Proteins found in the droppings, saliva, and body parts of cockroaches.

Risk Factors

Several factors increase the likelihood of developing allergic rhinitis, including:

  • Family history of allergies: Children with parents who have allergies, asthma, or eczema are more likely to develop allergic rhinitis.
  • Exposure to allergens: Being exposed to common allergens, such as pollen, dust mites, or pet dander, increases the risk.
  • Asthma or eczema: Children with asthma or eczema are more likely to develop allergic rhinitis.
  • Environmental factors: Children who live in urban areas with high pollution levels or who are exposed to tobacco smoke are at higher risk.

Diagnosis

Diagnosing allergic rhinitis typically involves a physical examination and a review of the child’s symptoms. The diagnostic process may include:

  • Medical history: The doctor will ask about the child’s symptoms, potential triggers, family history of allergies, and environmental exposures.
  • Physical examination
    • The doctor will examine the child’s nose, throat, and eyes for signs of inflammation or allergic reactions.
    • During the exam, your child’s doctor might also notice:
      • Dark circles beneath the eyes
      • Creases below the eyes
      • Swollen nasal tissues inside the nose
  • Allergy testing: To identify specific allergens, the doctor may recommend allergy testing, such as:
    • Skin prick test: Tiny amounts of potential allergens are applied to the skin to see if a reaction occurs.
    • Blood test (RAST or ImmunoCAP): A blood test can measure the level of antibodies to specific allergens.

Treatment Options

The goal of treatment for allergic rhinitis is to relieve symptoms, reduce inflammation, and avoid triggers. At Gertrude’s Children’s Hospital, we provide comprehensive care and treatment options tailored to each child’s needs.

  • Avoiding allergens:
    Identifying and minimizing exposure to allergens is a key part of managing allergic rhinitis. Steps to reduce allergen exposure include:

    • For pollen: Keep windows closed during high pollen seasons, and have your child shower and change clothes after playing outside.
    • For dust mites: Use dust-proof covers on pillows and mattresses, wash bedding frequently in hot water, and reduce carpeting.
    • For pet dander: Limit your child’s exposure to pets, especially in bedrooms, and regularly bathe pets to reduce dander.
    • For mold: Keep indoor areas well-ventilated and clean to prevent mold growth.
  • Medications:
    Several medications can help control the symptoms of allergic rhinitis:

    • Antihistamines: These medications, such as cetirizine, loratadine, or diphenhydramine, can reduce sneezing, itching, and runny nose by blocking the effects of histamine.
    • Nasal corticosteroids: These prescription nasal sprays, such as fluticasone or mometasone, reduce inflammation in the nasal passages and provide long-term relief of nasal congestion and other symptoms.
    • Decongestants: Decongestants, such as pseudoephedrine, may be used for short-term relief of nasal congestion, but they are not recommended for long-term use in children.
    • Eye drops: Antihistamine or anti-inflammatory eye drops can relieve itching and swelling in the eyes.
  • Immunotherapy (allergy shots or tablets):
    For children with severe allergic rhinitis that does not respond to medications, immunotherapy may be recommended. This involves exposing the child to gradually increasing amounts of the allergen over time to desensitize the immune system. Immunotherapy can be administered as allergy shots or sublingual tablets and can provide long-term relief from allergic symptoms.
  • Saline nasal irrigation:
    Saline nasal sprays or rinses can help flush out allergens from the nasal passages and reduce congestion.

Allergic Rhinitis in Children

Allergic rhinitis cannot be cured, but its symptoms can be effectively managed through avoidance of allergens, medications, and, in some cases, immunotherapy.

Allergic rhinitis symptoms, such as sneezing, runny nose, and itchy eyes, tend to last longer than a cold and may worsen after exposure to allergens. Unlike colds, allergic rhinitis does not cause fever or body aches.

Children with allergic rhinitis are at higher risk of developing asthma, especially if they have a family history of asthma or other allergic conditions. Managing allergic rhinitis can help reduce the risk.

Avoiding allergens that trigger your child’s symptoms is the best way to prevent allergic rhinitis. Keeping windows closed during pollen season, using air purifiers, and reducing dust and pet dander at home can help.

Immunotherapy may be recommended for children with severe allergic rhinitis who do not respond well to medications or for those who experience year-round symptoms.
