Prevalence and Mortality Rates of Systemic Lupus Erythematosus and Causes of Death in SLE Patients in Finland

Abstract

AbstractNationwide prevalence and mortality rates in systemic lupus erthematosus (SLE) were estimated using a computer file of all hospital discharge records and cause of death statistics from 1972 to 1978. Age-specific and sex-specific prevalence rates were obtained from 1976 to 1978 and mortality rates from 1972 to 1978. In December 1978 the prevalence of SLE was 28: 100000. The overall mortality rate was 4.7 per million person-years in 1972–78. Active lupus nephritis, vascular events and infections were the most frequent causes of death in SLE patients.
