Effect of various drugs used in conservative therapy of hepatorenal syndrome: a retrospective drug utilization study

Abstract

To analyze the impact of various drugs used in conservative therapy on renal failure and mortality in hepatorenal syndrome (HRS) at a tertiary care teaching hospital. Materials and Methods: Retrospective review of hospital admission records was conducted for case records with HRS as diagnosis. Demographic and clinical data and drug utilization pattern were collected in a pre-designed patient information sheet. Impact of various drugs especially hepatoprotector antioxidant, silymarin, on survival benefi ts in terms of number of patients alive, change in mean arterial pressure (MAP) and change in serum creatinine at the end of treatment period were estimated by univariate and followed by multivariate analysis. Results: Of the total 89 case records, 31 met the eligibility criteria and were included in the analysis. On multivariate analysis, a signifi cant correlation between use of intravenous fl uids (IVFs) and survival benefi ts was observed (P < 0.05); wherein patients treated with IVFs had an increase in log odds of survival by 2.42 (95% CI = 1.06 to 121.13) as compared to patient not treated with IVF. However, MAP was not affected by any of the treatment modalities. While change in serum creatinine level was not signifi cantly (P = 0.06, regression correlation = −0.3) correlated with duration of treatment with IVFs. Conclusion: Use of IVFs may be associated with better short-term survival benefi ts and favor HRS reversal. Use of silymarin as hepatoprotector antioxidant has no benefi cial effects on HRS reversal or survival benefi ts.
