Abstract
Two hundred seventy-one patients with unequivocal systemic scleroderma for whom the diagnosis was first established at the Mayo Clinic between January 1, 1945, and December 31, 1952, have been studied. Follow-up information was obtained 5 to 13 years after the diagnosis at the clinic concerning 236 of these patients, 115 of whom were dead. The cases were analyzed in an effort to determine what factors had a bearing on prognosis. The following seemed to bear little relation to the ultimate prognosis: sex, mode of onset, Raynaud's phenomenon, involvement of lungs and periodontal membrane, calcinosis cutis, and trophic changes. The following were considered poor prognostic omens: cardiac or renal involvement, significant elevation of the erythrocyte sedimentation rate, and anemia. The prognosis in systemic scleroderma was found to be worse than previous reports had indicated. This study yielded no basis for the subdivision of systemic scleroderma into acrosclerosis and generalized progressive scleroderma.
