    Abstract:
    Contrast media induced nephropathy (CIN) results in significant morbidity and mortality. We therefore investigated whether theophylline (adenosine antagonist) reduces the incidence of contrast media induced nephropathy. Two hundred and eighty patients were randomly assigned to prophylactic administration of hydration with sodium bicarbonate plus theophylline (either orally or intravenously) (n=128) or hydration with sodium bicarbonate only (n=152). Blood Urea, creatinine, and glomerular filtration rate (MDRD) were measured before and after administration of contrast media. Both groups were similar in clinical characteristics and amount of contrast used. Theophylline prophylaxis significantly reduced the incidence of CIN (1.6% vs 7.9%; P= 0.015). Compared to low-risk patients, Theophylline prophylaxis significantly reduced the incidence of CIN in moderate and high-risk patients (0% vs 8.8%; P= 0.022 and 9.1% vs 42.1%; P= 0.014 respectively). In conclusion, prophylactic administration of theophylline reduces the incidence of CIN in moderate and high-risk patients for CIN.
