title: [Selective IgA deficiency in systemic lupus erythematosus (author's transl)].
abstract: The case of a 23 year-old female with a diagnosis of systemic lupus erythematosus associated to selective IgA deficiency is reported. The patient persistently had serum IgA levels below 0.05 mg/dl, while the remaining serum immunoglobulins were normal. No salivary IgA was detected, and the karyotype disclosed no abnormalities of the chromosome 18. In the in vitro immunological study a normal number of B and T lymphocytes was found, and decreased production of all surface immunoglobulins was observed.
