Transient panhypogammaglobulinaemia and B-lymphocyte deficiency in a patient with neuropsychiatric systemic lupus erythematosus after immunosuppressive therapy
Abstract:Panhypogammaglobulinaemia is a rare complication of systemic lupus erythematosus (SLE), but its cause and mechanism are unclear. We observed transient panhypogammaglobulinaemia in a patient with neuropsychiatric SLE after treatment with prednisolone and cyclophosphamide. After the patient developed recurrent infections, laboratory findings disclosed panhypogammaglobulinaemia with B-lymphocyte deficiency. The serum immunoglobulin level returned to the normal range after the prednisolone was tapered off. Because… Show more
Measurement of immunoglobulin levels is useful in SLE to identify coexisting antibody deficiency and the later development of hypogammaglobulinaemia. This allows monitoring and appropriate treatment to be instituted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
