Effect of hyperbaric oxygen therapy on amphotericin-B induced acute renal failure in rats

Research output: Contribution to journalArticlepeer-review


AIM: Acute renal injury may occur after amphotericin B (AmB) administration. The hypothesized injury mechanism is renal vasoconstriction and direct toxic damage. Hyperbaric oxygen therapy (HBO) is indicated for treatment of many ischemic events but not for acute renal failure (ARF). The aim of this study was to investigate the role of HBO therapy in AmB induced ARF.

METHODS: ARF was induced in 41 Sprague-Dawley rats by a single dose of 75 mg/kg AmB. The rats were randomly divided into two groups; one group was treated with daily HBO for 3 consecutive days. The control group received no HBO treatment. Parameters of renal function were taken on the 5th day after AmB administration.

RESULTS: Forty-one rats were treated with AmB, 21 received HBO and 20 served as controls. Body weight loss following the administration of AmB was 13.5+14.7% in the HBO treated rats, as opposed to 24.6+5% in the control group (P=0.004). Serum creatinine and urea were 0.49+0.13 mg/dL and 200.63+87.82 mg/dL in the treatment group and 0.70+0.22 mg/dL and 368.01+169.35 mg/dL, respectively in the control (P=0.001).

CONCLUSION: In this model of AmB-induced ARF, HBO treatment alleviated renal injury as reflected by changes in serum creatinine and urea levels.
