Abstract

Severe Combined Immunodeficiency (SCID) consists of a heterogeneous group of genetic disorders characterized by an arrest in T lymphocyte development which is variably associated with an abnormal differentiation of B and NK cells. In order to depict the clinical state of Iranian patients with SCID, records of forty patients were reviewed. Patients were classified based on the flow cytometry data in two groups of B− and B+. In thirty two families (80%) parents were consanguine and in 17 families (50%) there were affected members other than proband. We showed that autosomal forms of SCID might be more frequent due to higher rate of consanguineous marriages. Alongside several infective complications, complicated Bacillus Calmette-Guérin (BCG) vaccination was documented in 18 cases (45%) following the routine vaccination at birth. BCG immunization is still a part of standard vaccination for newborns in developing countries; whereas in communities with a better health condition it could be held for a few months and performed for kids whose immune system sounds intact. We discuss where consanguine mating is common, a test of screening should be run timely. A complete blood count of cord blood could reveal lymphocytopenia at birth; this helps early diagnosis. Genetic consultation would help the families with affected members preventing new SCID offspring.
