Gender Differences in Aminoglycoside Induced Nephrotoxicity: A Prospective, Hospital - Based Study
Tue, 2011-03-08 13:28 — Professor Waleed M. Sweileh
Aim: Impact of gender on aminoglycoside induced nephrotoxicity is still controversial and inconclusive. The objective of this study was to investigate the nephrotoxic potential of amikacin (AK) and gentamicin (GM) in male and female hospitalized patients.
Methodology: A one-year, non-interventional prospective study of patients administered either GM or AK. The study was carried out at the internal medicine department of Al-Watani governmental hospital. Nephrotoxicity was defined as a blood creatinine (Cr) increase of >= 0.5 mg/ dL from the basal (normal) Cr level. Data were entered and analyzed using SPSS 16.
Results: A total of 94 patients were identified (GM, n = 45 and AK, n = 49). Male and female patients on GM had comparable characteristics except that males had significantly higher number of co-existing chronic diseases. No gender differences were observed in gentamicin induced nephrotoxicity (37% in males versus 33.3% in females, P = 0.8). Male and female patients on AK were also comparable in demographic and clinical characteristics. However, significant differences in gender susceptibility were observed with AK induced nephrotoxicity (31.6% in females versus 6.7% in males, P = 0.043). Pattern of serum creatinine changes in patients on GM were comparable between males and females. However, in females on AK, s.cr levels were rising sharply after the fourth day compared with that in male patients on AK.

TwitterA Prospective Comparative Study of Gentamicin- and Amikacin-Induced Nephrotoxicity in Patients with Normal Baseline Renal Function
Sun, 2010-04-11 17:05 — Professor Waleed M. SweilehThe aim of this study was to compare the nephrotoxic potential of amikacin (AK) and gentamicin (GM) in patients with normal baseline renal function. This study was a 1-year, non-interventional prospective study of patients administered either GM or AK. The study was carried out at the internal medicine department of Al-Watani governmental study. Nephrotoxicity was defined as a serum creatinine (SCr) increase of >or=0.5 mg/dL from the basal (normal) SCr level. The two groups (GM, n = 45 and AK, n = 49) were similar in population composition, and underlying pathological and infectious processes requiring antimicrobials. No significant difference in age was found between patients in the GM and AK groups, P = 0.83. Patients in the GM group received comparatively lower doses than those in the AK group (mean = 2.5 mg/kg/day and 14.4 mg/kg/day, respectively) but the duration of treatment was similar. Sixteen of 45 patients receiving GM (35.6%) and eight of 49 patients receiving AK (16.3%) developed nephrotoxicity, P = 0.033. Single daily dosing with GM, regardless of the total daily dose, produced less nephrotoxicity than multiple dosing. In contrast, AK given at a total dose of 1 g daily, showed no benefit of single dosing compared with multiple dosing. In patients with initial normal renal function, GM was significantly more nephrotoxic than AK. Multiple dosing of GM was more nephrotoxic than single dosing. AK-induced nephrotoxicity was not significantly dependent on dosing frequency.
