بررسی کارآیی اینترالیپید در کاهش سمیت کلیوی مرتبط با آمفوتریسین B

Background: Amphotericin B Deoxycholate (ABD) has been the best therapeutic agent for treatment of most systemic fungal infections. However, untoward adverse effects like nephrotoxicity may limit its appropriate therapeutic use. We studied administration of fat emulsion early after infusion of ABD to evaluate its effects on ABD-associated nephrotoxicity.Methods: This study was a randomized clinical trial. Patients with fungal infections admitted in Amir-Alam and Imam-Khomeini University Hospitals, Tehran, Iran, entered the study during 1390- 1391. The patients were randomized to intervention and control groups. In both groups, patients received 1mg/kg/day ABD in dextrose 5%. In intervention arm, the patients additionally received intralipid 10% daily that was started as soon as possible within one hour after infusion of ABD. ABD-associated nephrotoxicity (a minimum 50% increase in baseline serum creatinine to a minimum of 2mg/dl), daily serum creatinine changes during first two weeks of treatment and some other relevant indices of renal function were compared between groups. ABD-related hypokalemia was also compared as an additional target. Results: Thirty one patients entered the study. ABD-associated nephrotoxicity and values of other relevant indices of renal function were not different between intervention and control groups (P>0.05). Daily changes in serum creatinine level within first two weeks of treatment in both groups were not also statistically different (P=0.62). Furthermore, ABD-related hypokalemia was not significantly different between groups (P=0.47).Conclusion: Administration of intralipid 10% early after infusion of ABD in dextrose 5% does not have any effect in decreasing ABD-associated nephrotoxicity. Moreover, it does not have any significant effect on ABD-related hypokalemia.
