A retrospective analysis of 18 patients followed in a Nephrology Service of the Hospital Pereira Rossell between July 1989 - July 2001 is presented; clinical and immunological features, pathological findings, course and complications. 66% were female, the mean age at diagnosis was 11 years (r: 3y10m-14y11m). 89% presented severe multysistemic involvement. Fever, weakness, malaise and cutaneous involvement were seen in 89%, arthritis in 67%, nephrologic disease in 89%, cardiovascular involvement in 22%, respiratory disease in 22%, central nervous system manifestations in 16,6%. Hematologic abnormalities were seen in 100% of the patients. Antinuclear antibodies were increased in 94,4%, anti ds DNA were positive in 94%, hypocomplementemia was found in 94%. The follow up was of 1 week - 17 years (x: 5y 5m). All the patients received corticosteroids, 9 methylprednisolone bolus. Inmunosupresors were indicated in 16 patients: cyclophosphamide and/or azathioprine. Two patients died (11%), is in remission without treatment one patient, in remission with treatment nine patients, in activity four cases.
