Introduction:

Autoimmune diseases are in second place, after infections to suspect primary immunodeficiency diseases.

Objective:

To determine the behavior of autoimmune diseases in patients with primary immunodeficiencies.

Methods:

A case control study was carried out in the allergy and immunology service of Bayamo, Granma between 2013 and 2022. The universe was studied as a whole, the study group with 38 patients diagnosed with primary immunodeficiency and the control group with 76 patients without immune system compromise. The SPSS 25 statistical program, absolute and relative frequencies, odds ratio and chi-square were used.

Results:

The manifestations suggestive of autoimmunity in patients with PID was 39.47% and in controls 3.95%, OR = 15.869 and p = 0.000 and the most frequent were: monoarticular pain in 6 patients (33.33%), polyarthralgia, dermatitis and alopecia with 3 cases (16.67%) each one, pain in dorsal spine and subcutaneous nodule, one patient (5.56%) each one. Immune diseases associated with PID were: celiac disease (30.71%), vitiligo (23.07%), fibromyalgia (15.38%), erythema nodosum, eosinophilic gastritis, pernicious anemia and vasculitis with 7.69% each.

Conclusions:

Autoimmune manifestations and diseases prevailed in patients with PID, in both cases were more frequent in patients older than 18 years. The immunodeficiencies most frequently associated with autoimmune disorders were those of antibodies and those with some dysregulation component.
