Clinical Trial Summary

SBP is a common complication of cirrhotics with associated increased mortality. After first episode of SBP there is increased risk of again developing SBP, with increased chance of developing resistant organism. So after the first episode of SBP, prophylaxis for prevention of second episode onwards is mandatory and therefore Rifaximin or Norfloxacin is considered. It has been seen that apart from preventing SBP they have other benefits with negligible side effects and therefore it is to be seen what other benefits including mortality benefits these drugs can confer.


Clinical Trial Description

Hypothesis:-Rifaximin will be more effective in decreasing the incidence of SBP in patients with cirrhosis and prior episode of SBP AIM:-.To study the efficacy and safety of Rifaximin vs Norfloxacin in preventing incident SBP, preventing non-SBP infections, and improving transplant free survival in patients with cirrhosis and previous episode of SBP Methodology Single centered Open labeled Randomized Controlled Trial Randomization will be done by block randomization method taking block size as 10. Data will be entered in Microsoft Excel and will be analysed by SPSS Version 28.Categorical Data will be represented as frequency (%) and will be analysed using Chi square or Fisher Exact Test as appropriate.Continuous Data will be represented as Mean +/- SD and compared using Student T test or Mann Whitney as per normality conditions are met or not.Beside this an appropriate analysis like survival analysis will be carried out at the time of Data Analysis.P value <0.05 will be considered as significant. Rescue therapy: To be given to patients who develop SBP while on secondary prophylaxis, these patients will initially be treated by iv medication in hospital settings followed by change in therapy. - Patients in Rifaximin limb developing SBP will switch to Norfloxacin - Patients in Norfloxacin limb developing SBP will switch to Rifaximin Treatment Failure: Defined as development of SBP at end of 6 months or 1 year of treatment. Study population: age >18 years with prior incident SBP Study design: Randomised case controlled trial Study period: 1year after ethical clearance Sample size: 280 (140 in each arm) Intervention: This RCT will be conducted at ILBS New Delhi Monitoring and assessment: Monitoring will be done forall the parameters of the objective. Documentation will be done for any adverse effects which will happen. STATISTICAL ANALYSIS: Assuming incidence of SBP over 6 months is 4% in Rifaximin & 15% in Norfloxacin Alpha 5% and power 80%. Enrollment of 260 cases (130 in each arm). Assuming dropout rate 10%.Total study cases calculated as 280 (140 in each arm). Random allocation in each arm by block method taking 10 as block size ;
