Abstract

Primary immunodeficiencies (PID) are a heterogeneous group of diseases that cause alterations in the immune system, leading to the increased susceptibility to infections, autoimmune diseases, and malignancies. The aim was to evaluate the presence of clinical manifestations and diagnoses of asthma, rhinitis, and atopic dermatitis in patients diagnosed with PID, and correlate these with allergen sensitization verified by skin prick testing (SPT). This cross-sectional, descriptive, and observational study was conducted from February 2015 to February 2016. We performed a medical report analysis and SPT for aeroallergens in patients with a PID diagnosis. Thirty-one patients with a PID diagnosis were included. The mean age of the participants was 15.41 years. From the 31 patients, 28 had symptoms suggestive of allergic disease (asthma, rhinitis, and atopic dermatitis) and only 7 presented positive SPT for at least 1 aeroallergen. The frequency of allergenic sensitization in the group of patients with PID and symptoms suggestive of asthma, rhinitis, or atopic dermatitis is lower than that found in the general population, probably due the impairment of IgE formation secondary to their immunologic alterations.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Allergies & Environmental Factors

Environmental factors are strongly associated with the prevalence of allergies and are an increasing health concern worldwide. Discover the latest research on Allergies and Environmental Factors here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. Discover the latest research on atopic dermatitis here.
