Kidney crisis in systemic sclerosis.Rocz Akad Med Bialymst. 2005; 50 Suppl 1:294-6.RA
Renal crisis in systemic sclerosis occurs in the group of patients with rapid and aggressive course of the disease, often after several years of the ailment and with the diffuse form. Scleroderma renal crisis (SRC) is most frequently characterized by malignant hypertension, renal insufficiency, and less often by the symptoms of microangiopathic hemolytic anemia. Renal crisis symptoms appear suddenly and are not usually preceded by significant prodromal symptoms. SRC is always life-threatening and requires specific treatment with drugs blocking angiotensin-converting enzyme. Early diagnosis and introducing appropriate treatment give a patient a chance to survive SRC episode and improve his prognosis. SRC is of great importance to clinicians as it still causes high mortality rate. Chronic and subacute renal crisis is connected with a small risk of acute renal failure. However, it gradually leads to a substantial dysfunction of this organ. Thus, a useful examination in the diagnostics of chronic renal crisis is checking the vascular flow in renal cortex and evaluating intrarenal resistance.
