title: Male lupus: prevalence of IgA deficiency, 7S IgM and abnormalities of reticuloendothelial system Fc-receptor function.
abstract: Serological studies conducted on sera from a group of 31 male SLE patients revealed a 32% prevalence of 7S IgM and a 9.7% prevalence of IgA deficiency. Previous reports using similar methods indicated a higher (43-50%) prevalence of 7S IgM than was found in studies involving predominantly females with SLE (15-18%), and an overall prevalence of IgA deficiency ranging from 0.95% to 4.6%. Males resembled females in the prevalence of Fc-receptor specific reticuloendothelial system dysfunction, correlating with levels of circulating immune complex-like material and disease activity.
