| Abstract: | The prevalence of autoimmune diseases, including systemic lupus erythematosus, is increased in failure of certain host defence mechanisms. Systemic lupus erythematosus, however, has not been recorded as a late complication of the Staphylococcus aureus hyperimmunoglobulinaemia E (hyper-IgE) syndrome. Such a case was investigated in a man suffering from a classic example of the syndrome. Antinuclear antibodies were analysed on a molecular basis. The emergence of immunological and clinical features of systemic lupus erythematosus in patients with defective host defence mechanisms against staphylococcal infections is unlikely to be fortuitous and may help elucidate the pathogenesis of systemic lupus erythematosus. The observations will also aid the long term management of patients with S aureus hyper-IgE syndrome. |
