Introduction:

inborn errors of immunity or primary immunodeficiencies are characterized by increased susceptibility to infections due to defects in the development or functioning of the immune system. Diagnosis should include clinical evaluation, immunological analysis, genetic evaluation, routine follow-up, diagnostic re-discussion and clinical management. There is no clear guidance on this issue under resource-limited conditions.

Objective:

to design a model for clinical history in patients with suspected inborn error of immunity.

Methods:

a review of symptoms to be considered in the clinical history of patients with inborn errors of immunity was carried out. Working groups were formed among members of the provincial group of Immunology in Pinar del Rio province, with the subsequent discussion of the aspects to be included in the history.

Results:

five tables were designed to collect: informed consent; personal pathological antecedents related to 148 clinical manifestations in correspondence with allergic, infectious, inflammatory, autoimmune, non-immune, neoplastic and other phenotypes. Family pathologic history and family tree; physical examination and summary of clinical phenotypes, diagnostic discussion and classification of the patient are presented.

Conclusions:

the interviews, physical examination, personal and family pathologic history, as well as the adequate design of the clinical history, are considered essential elements for the approach to the diagnosis of inborn errors of immunity. A patient registry should be available to enable early diagnosis and timely treatment of primary immunodeficiency.
