To the editor: Sussman and associates (1) report a correlation between the administration of high-dose steroid therapy and the occurrence of panhypogammaglobulinemia in a case of systemic lupus erythematosus. We report a further case of panhypogammaglobulinemia occurring in the context of systemic lupus erythematosus, in which reductions of serum immunoglobulins coincided with the administration of azathioprine.
