Abstract
Patients (72) were studied whose sera contained antibodies to a cytoplasmic antigen, Ro. The majority had clinical features typical of systemic lupus erythematosus and there appeared to be an overlap with Sjogren''s syndrome. Certain patients with lupus responded predominantly to cytoplasmic antigens and in some cases were ANA [antinuclear antibodies] negative. Demonstration of this system is important in enlarging the serologic spectrum characteristic of SLE patients, and also may be an important marker for systemic disease in patients with predominantly cutaneous involvement.
