A patient with scleroderma has been maintained on continuous ambulatory peritoneal dialysis (CAPD) for the past 18 months after having developed associated renal failure. Peritoneal clearances, pulmonary function tests, and hand studies have shown seasonal changes from summer to winter with ambient temperature variations. Rehabilitation and quality of life have been acceptable, blood pressure has been well controlled off all medications, and there has been relatively little disease progression. Attempts have been made to maintain low-dose captopril therapy to suppress plasma renin activity. This case suggests that CAPD is an acceptable and, perhaps, indicated treatment modality for renal failure associated with scleroderma.
