In 2017, the Pediatric Hospital of Sinaloa (PHS) began its affiliation to the registry of patients with primary immunodeficiency or inborn errors of immunity (IEI) on the platform of the Latin American Society for Immunodeficiencies (LASID). During this period, twelve cases with IEI have been diagnosed and treated at the hospital. The age category at the time of diagnosis varied from two days to sixteen years old, and the range of the onset of the symptoms varied from nineteen days to four years, with a predominance of males (67%). The most frequent IEI was predominantly antibody deficiency (33.3%), followed by defects in the number or function of phagocytes (16.6%), autoinflammatory disorders (16.6%), immunodeficiencies that affect cellular and humoral immunity (16.6%), combined immunodeficiencies associated with syndromic findings (8.3%), and defects in intrinsic and inborn immunity (8.3%). 84% of patients received intravenous immunoglobulin and, in one case of a patient with Wiskott-Aldrich syndrome, a pathogenic variant in the WAS gene was identified; a patient received hematopoietic stem cell transplantation, 33.3% of patients died, of which 25% died of sepsis and 8.3% died of massive hemorrhage. The registry of IEI provides information about epidemiological data, incidences, prevalence, diagnoses, and treatments, which will favor the development of new health policies for obtaining resources and tools to improve the care models.
