RESUMEN
Variable Common Immunodeficiency (VCI) can course with non necrotizing epithelioid granulomatosis of sarcoid type. Although this entity is frequently referred, it is rare and its significance is not clear. The immunological study and response to treatment with corticoids and i.v. immunoglobulins of a patient is who suffered VIC with sarcoid granulomas on lymph node, liver and skin biopsies is here presented. The association between VCI and granulomatosis is discussed.

Antibodies to antigens codified by the env and gag genes of HIV were separately assayed for in the sera of 150 infected people. From a practical standpoint, enzyme immunoassay was a more convenient and reliable technique than Western blot. Anti-env was positive in 100% and anti-gag in 70% of the cases. A positive anti-env test was confirmatory of serological diagnosis, but lacked any prognostic value. A higher frequency of negative results for anti-gag antibody was significantly associated with the presence of more severe clinical manifestations, more profound impairment of lymphocyte subpopulations (especially CD4 cells), and the finding of HIV antigens in blood. The absence of anti-gag antibodies, which seem to behave as protective, is an unfavorable feature in the clinical and immunological evaluation of patients.
