Early detection of radio contrast media induced nephropathy

ABSTRACT

Radio contrast media [RCM] induced nephropathy has been defined as an acute impairment of renal function following exposure to radiographic contrast materials after excluding other causes of renal impairment [Bersketh and Kjellstrand, 1984]. The aim of the present work is early detection of asymptomatic radio-contrast media associated nephrnpathy and its possible effect on glomerular-and tubular functions. The study included 35 subjects divided into two groups Group I 20 patients received RCM urographin l ml/kg body weight and Group II 15 healthy persons as normal control who received normal saline as a placebo. Both groups were subjected to thorough clinical examination and the following laboratory investigations urinary microalbuminuria before as well as 24 hours after RCM to test glomerular function urinary alkaline phosphatase before RCM administration as well as 5 hours. 24 hours as well as 5 days after as a test for tubular function. The results of the present study showed significant increase in microalbuminuria in group I patients after administration of RCM, also there was statistically significant increase in the mean values of urinary alkaline phosphatase observed 5 hours. 24 hours, and 5 days after RCM
