title: [Scleroderma renal crisis. 7 cases and review of the literature].
abstract: We report a series of seven patients who had scleroderma renal crisis. Their primary clinical and laboratory features along with the details of their management were compared with those of similar cases from the literature. The seven patients died within one to four months of the diagnosis with a pattern of acute renal failure, left ventricular failure and malignant hypertension. Histopathologic examination was performed in four of the patients, in two of whom it revealed thickening of the wall of the interlobular arteries related to the scleroderma, and in the other two patients nonspecific lesions of malignant hypertension. This histopathologic particularity led us to propose, on the basis of multiple renal biopsies performed in patients with scleroderma, a lesion chronology of the kidney in patients with scleroderma. Nevertheless, the triggering factors and pathophysiologic mechanisms of scleroderma renal crisis remain unclear and its prognosis is severe. Early treatment with angiotensin-converting enzyme inhibitors and other vasodilatators administered intravenously can prevent death and dialysis.
