ABSTRACT

Background: Scleroderma is a rare autoimmune disease occurs with an annual rate of about 2-20 cases / 1 million people. Objectives: To evaluate the common clinical and laboratory manifestaions of scleroderma associated renal disease. Subjects and method: A restrospective study of clinical, urinary analysis, biochemical and blood count analysis and renal artery dopper ultrasonography indexes in 147 patients with scleroderma. Results: The commonest nonrenal clinical manifestations were skin thickening (100%), pigmentation (71,43%), arthalgia/ arthritis (83%), Raynaud phenomenon (62,58%) and gastroentrological syndrome (50,34%). 11,56% of patients had signs and symptoms of kidney involvement such us hypertension (10,2%), edema (9,52%), oliguria (3,4%). 14,29%, 10,88% and 18,18% of patients had abnomalities on urinary analysis, increased blood urea and renal artery stenosis on dooper ultrasonography, respectively. Conclusion: 11,56% of patients had rena manifestationsin clinical, the commonest is hypertension, edema and oliguria. 14,29%, 10,88% and 18,18% of patients had positive proteinuria of hematuria, increased blood urea and renal artery stenosis on dopper ultrasonography, respectively.
