Abstract
PURPOSE: Although it is known that liver disease predisposes to aminoglycoside nephrotoxicity, specific features of such disease that may predispose to aminoglycoside-induced renal injury have not been identified. We sought to identify such features. PATIENTS AND METHODS: We undertook a retrospective review of the charts of 42 consecutive patients with biliary obstruction and/or cholangitis who had received more than three doses of an aminoglycoside. RESULTS: Comparison of patients in whom aminoglycoside nephrotoxicity did and did not develop revealed no differences in age, race, sex, dose, and duration of aminoglycoside therapy; mean peak and trough aminoglycoside levels; initial pre-treatment levels of serum creatinine, aspartate transaminase, alkaline phosphatase, or albumin; or prothrombin time. The initial pre-treatment serum bilirubin level was higher in the patients in whom aminoglycoside nephrotoxicity developed (12.2 +/- 8.8 mg/dl versus 3.4 +/- 3.2 mg/dl, p less than 0.01). Aminoglycoside nephrotoxicity occurred in eight patients (19 percent): in seven of 15 patients (47 percent) with an initial bilirubin value greater than 5.0 mg/dl, but in only one of 27 patients (4 percent) with an initial bilirubin value below 5.0 mg/dl (p less than 0.01). The pre-treatment bilirubin level correlated with the change in creatinine during aminoglycoside therapy (n = 42, r = 0.66, p less than 0.01). CONCLUSION: Aminoglycosides should probably be avoided in patients with biliary obstruction and a high serum bilirubin level.
