Diagnosing Atopic Triad

Diagnosing Atopic Triad

Responding to Julio

This is a great post, Julio. Being presented with a young patient with an atopic triad can be a challenging diagnosis to carry out. A differential diagnosis must be carried out in order to determine the condition the child is suffering from. Diagnosing all of the conditions of the atopic triad can be time-consuming as well as add to the costs of care for the patient. Therefore, the diagnosing health care professional can dismiss some of the conditions based on the symptoms the patient manifests and the conditions related to the development of the condition. For instance, hay fever develops mostly during the pollen season. Atopic dermatitis is the major condition to be manifested in the majority of the patients among the three conditions of atopic dermatitis. Diagnosis of atopic dermatitis should consider all the risk factors, including the other conditions of the atopic triad, such as asthma and allergic rhinitis, and the patient’s medical history and their family’s history of allergies (Fleming et al., 2020).

Responding to Gurpreet

This is a good post, Gurpreet. Diagnosing atopic triad requires a lot of care to avoid overprescribing medications and risk overdoses and other medication errors and related outcomes. As a healthcare professional, when presented with a patient showing symptoms of an atopic triad, it is important to be aware of the atopic march as a pattern of atopic triad progression. The atopic march is the progression of one of the allergic conditions of the atopic triad. The atopic march explains how allergic diseases progress from atopic dermatitis to allergic asthma and, eventually, allergic rhinitis (Aw et al., 2020). This progression can lead to the development of other conditions and symptoms, such as pain in the ear, as presented by the young patient. Therefore, being aware of the progression and atopic march can help develop a clear diagnosis and manage the conditions effectively without risking the health of the patient.

Due to the information obtained from the patient and his mother, I chose three diagnoses: allergy-induced asthma, acute otitis media, and atopic dermatitis.

CC: “cough and sounds “wheezy” for the last two days.”

Allergy-induced asthma (J45.988). Asthma is a disease that obstructs the airways, causing the movement of air that is expired to be restricted. Some factors that can cause air obstruction are inflammation, bronchospasm, and large amounts of respiratory secretions (Chabra & Gupta, 2022). The most reported symptoms are cough and wheezing. Some differential diagnoses for this condition are allergic rhinitis, sinusitis, and viral bronchiolitis (Chabra & Gupta, 2022). The pharmacological treatment that I will prescribe for this condition is a short-acting beta agonist (SABA) such as albuterol in an inhaler at a dose of (90 micrograms/dose metered-dose inhaler) 90-180 micrograms (1-2 puffs) every 4- 6 hours when required (online. epocrates.com, 2022).

CC: “Right ear hurts.”

Acute otitis media (H66. 91). Acute otitis media is an infection generated in the middle ear; this condition has a high incidence in pediatric patients, causing regular visits to the emergency department. The most reported symptoms are ear pain, although sometimes irritability, headache, difficulty sleeping or staying asleep, lack of appetite, anorexia, vomiting, or diarrhea may occur. Fever usually occurs in 66.66% of cases (Danishyar & Ashurst, 2022). Some differential diagnoses for this condition are external otitis and pediatric allergic rhinitis (Danishyar & Ashurst, 2022). The pharmacological treatment that I will prescribe for this condition is oral analgesics such as Tylenol at a dose of children: 10-15 mg/kg orally/rectally every 4-6 hours when required, a maximum of 75 mg/kg/day, and ibuprofen at a dose de children: 5-10 mg/kg orally every 6-8 hours when required, maximum 40 mg/kg/day (online.epocrates.com, 2022). If the patient does not improve in 2 to 3 days, I will start antibiotic therapy. The first-line antibiotic treatment is amoxicillin at an initial dose of children: 80-90 mg/kg/day orally, given in divided doses every 12 hours for ten days (online.epocrates.com, 2022).

CC: ¨Dry, scaly patches on the child’s elbows and behind her knees.¨

Atopic dermatitis (L20.9): Atopic dermatitis is linked to eczema and is the most common chronic skin condition. Several etiologies, including genetic, environmental, and immune systems, can cause this condition. This condition begins with itching in childhood and presents with dry skin, eczematous lesions, and lichenification (Kolb & Ferrer-Bruker, 2022). Some differential diagnoses for atopic dermatitis are psoriasis and allergic contact dermatitis (Kolb & Ferrer-Bruker, 2022). I will prescribe emollients for the pharmacological treatment since they are the first-line medications and help moisturize the skin. If there is no improvement, I will start adjunctive therapy with intermittent topical corticosteroids such as hydrocortisone topical at a dose of (0.2 to 2.5%) and apply sparingly to the affected area(s) twice daily (online.epocrates.com, 2022).

A 5-year-old child and her mother are present at your clinic. The mother reports that the child has had a cough and has sounded “wheezy” for the last two days. She states that the child always gets like this when she is sick. She also reports that the child has complained that her right ear hurts. In addition, you notice dry, scaly patches on the child’s elbows and behind her knees.

What are your differentials and diagnosis? What would you prescribe for each condition?

Remember to include your rationales.

The young patient exhibits allergic rhinitis according to the brief and contradictory facts. Therefore, allergy combined with acute serous otitis media and allergy-induced asthma would be my top differential diagnoses. Since the child is five years old, the development of shorter, horizontal eardrum tubes may result in fluid buildup. Because I am afebrile, I would postpone giving antibiotics and instead treat each symptom separately at this time. The patient does, however, exhibit asthmatic symptoms as a result of the atopic triad presentation. As a result, a baseline peak flow meter test and a referral to an allergy specialist are required to determine triggers.

CC: “Wheezy for the last two days,” and the child always gets similar symptoms whenever she is sick.

Differential diagnosis

Allergy-induced asthma (J45. 901)-Asthma’s etiology may involve numerous factors. The cause is believed to result from hereditary and environmental factors. However, an excessive hypersensitive reaction is the leading cause of all forms of asthma(Chabra & Gupta, 2020). An IgE-mediated response is what is being described here. Eosinophils, lymphocytes, and mast cells increase due to an offending factor, such as an allergen or an environmental agent (such as air pollutants). The bronchial epithelium is harmed, and the airways are inflammation. Since the symptoms seem to be brought on by an allergen, asthma brought on by an allergy would be appropriate.

Allergic rhinitis (J30.9): Sneezing, postnasal drip, nasal pruritus, and nasal congestion are all signs of allergic rhinitis (AR), an atopic condition. It affects one in six people and is linked to high morbidity, severe productivity loss, and high healthcare expenses(Akhouri & House, 2020). In the past, AR was believed to be a nasal airway-specific disease. Nevertheless, the emergence of the unified airway hypothesis has categorized atopic dermatitis and asthma as linked illnesses that have common systemic pathophysiology, classifying allergic rhinitis (AR) as a component of a systemic allergic reaction(Akhouri & House, 2020). Approximately 20% of cases of AR are characterized as seasonal (intermittent), 40% as perennial (chronic), and 40% as having characteristics of both. Patients with AR may also experience concomitant allergic conjunctivitis, a dry cough, Eustachian tube dysfunction, chronic sinusitis, and nasal symptoms.

Treatment Plan: Short-acting inhalers are the most efficient strategy to reverse airway obstruction and deliver instant symptom relief. Beta-agonists like albuterol are the most commonly utilized medicines(Chabra & Gupta, 2020). Long-term treatment of asthma necessitates a multifaceted strategy that includes avoiding environmental triggers that might cause bronchoconstriction and airway inflammation, monitoring changes in disease activity, and occasionally allergen immunotherapy and medication therapy. The best way for people to control their asthma is to inhale corticosteroids. They reduce bronchial hyperresponsiveness and repress inflammatory changes in the airways. Compared to non-smokers, smokers with asthma receive less benefit from inhaled corticosteroids.

For intermittent asthma, the preferred therapy is a short-acting inhaled beta2 agonist. For persistent asthma, daily medication is recommended. The preferred treatment is a low-dose inhaled corticosteroid(Chabra & Gupta, 2020). A low-dose corticosteroid plus a long-acting beta2 agonist or a medium-dose inhaled corticosteroid is recommended. The preferred treatment is a medium-dose inhaled corticosteroid plus a long-acting beta2 agonist. The preferred treatment is high dose inhaled corticosteroid plus a long-acting beta2 agonist and considering omalizumab for people with allergies(Chabra & Gupta, 2020). The preferred treatment is a high-dose inhaled corticosteroid plus a long-acting beta2 agonist plus an oral corticosteroid; consider omalizumab for people with allergies.

Differential diagnosis

Acute serous otitis media (ICD-10 H65.01): An infection of the middle ear space is known as acute otitis media. Chronic suppurative otitis media (CSOM), acute otitis media (AOM), and otitis media with effusion are all included in this spectrum of illnesses (OME). Critical otitis media is the second most typical pediatric emergency room diagnosis following upper respiratory infections. Otitis media can occur at any age, but it is most frequently diagnosed between 6 and 24 months.

Otitis media (ICD-10 H66.90): Otitis media with effusion (OME) is a condition in which the middle ear is filled with fluid but does not exhibit acute infection symptoms. The tympanic membrane is pressed against the middle ear, and the Eustachian tube fluid accumulates. The pressure reduces sound conduction, inhibits the tympanic membrane from vibrating correctly, and thus impairs patient hearing. Although some clinicians advise saving the term “chronic otitis media” for patients in whom the tympanic membrane has perforated, chronic OME is defined as OME that continues for three months or more on examination or tympanometry.

Treatment Plan: Otitis media with effusion typically goes away independently with careful observation. Myringotomy with tympanostomy tube insertion is considered an effective treatment if persistent (Searight et al.,2020). A ventilation tube is used in this procedure to get air into the middle ear, which prevents fluid from building up again. Due to the growth and development of the Eustachian tube angle, which will enable drainage, many patients won’t require further therapy after this procedure. To ease their agony, we must inform them that acute serous otitis media (ASOM) is not an illness but a condition that can cause pain. Acetaminophen and ibuprofen sold over the counter for children should be used as directed on the label(Searight et al.,2020). The mother will be advised to return before the suggested three-day follow-up period if the earache does not go away after taking acetaminophen and ibuprofen.

CC: dry, scaly patches on the elbows and behind the knees

Atopic dermatitis (ICD-10 L20.9)-This long-term condition that causes pruritus typically begins in infancy and manifests as lichenification, eczematous lesions, and dry skin. Asthma, food allergies, and other IgE-related illnesses, such as allergic rhinitis, are thought to be connected to AD(Kolb & Ferrer-Bruker,2020). Atopic dermatitis has a complicated etiology, including environmental and genetic variables resulting in the immune system and epidermal abnormalities. The “atopic march” refers to the onset of the atopic trifecta, which includes atopic dermatitis, allergic rhinoconjunctivitis, and asthma, either simultaneously or one after the other. Patients with the atopic triad experience symptoms due to compromised skin, upper respiratory, and lower respiratory tract barrier(Kolb & Ferrer-Bruker,2020).

Dermatitis and Eczema (ICD 10 – L20.L30): The most prevalent type of dermatitis is eczema, sometimes referred to as atopic dermatitis. Genetic and environmental factors are believed to contribute to the etiology (Nemeth & Evans,2020). Although it can affect adults, eczema is more frequently found in youngsters. People with the condition often have infected, dry, and itchy skin. Eczema is commonly called the “itch that rashes” because of the dry skin that causes a rash when scratched or rubbed. Skin hydration is the most crucial aspect of treating eczema, followed by topical steroids for flare-ups.

Treatment Plan: The first treatment suggestions would be 1% hydrocortisone cream and an emollient-based ointment BID. To aid with “steroid fear,” a typical reason for treatment failure, the mother would be contacted with any queries regarding using steroids (Nemeth & Evans,2020). As they provide superior protection against xerosis, thick creams with reduced water content or ointments like petroleum jelly or aquifer are typically favored. However, be aware that they leave a greasy feeling (Nemeth & Evans,2020). Although the patient reports having dry, scaly skin, using the emollient may also comfort them. Additionally, it is advised to use mild body cleansers and laundry detergents while changing bed linens.

Follow up plan

Informed the patient to return in 3 days to evaluate how well the inhaler and ointments work. To prevent fungal infections, the mother and child will learn to use a spacer and cleanse their mouths after using the inhaler. Additionally, the mother will know when to seek emergency medical attention:

Fever > 101 that acetaminophen and ibuprofen cannot control.

Even with the usage of acetaminophen and ibuprofen, ear pain becomes intolerable.

breathing difficulties or breathlessness following the use of the inhalers

Suddenly, feel worried or experience a mental shift
looks cyanotic
