Outcomes in Patients With Cirrhosis on Primary Compared to Secondary Prophylaxis for Spontaneous Bacterial Peritonitis.

ABSTRACT: OBJECTIVES:Antibiotic prophylaxis is recommended for prevention of the first episode of spontaneous bacterial peritonitis (SBP; primary prophylaxis 1°) and subsequent episodes (secondary prophylaxis 2°). We aimed to compare outcomes in cirrhotic inpatients on 1° vs 2° SBP prophylaxis. METHODS:Data from North American Consortium for the Study of End-Stage Liver Disease were evaluated for cirrhosis details, reasons for admission/medications, inpatient course recorded, and outcomes over 90 days. Outcomes (intensive care units, acute kidney injury, inpatient/90-day mortality) were compared between the 2 groups after propensity-matching on admission model for end-stage liver disease (MELD) score and serum albumin. RESULTS:Among the 2,731 patients enrolled, 305 were on 1° and 187 on 2° SBP prophylaxis. After propensity-matching, 154 patients remained in each group. Patients on 1° prophylaxis were more likely to have admission systemic inflammatory response syndrome (P = 0.02), with higher intensive care unit admissions (31% vs 21%; P = 0.05) and inpatient mortality (19% vs 9%; P = 0.01) than the 2° prophylaxis group. Patients on 2° prophylaxis had higher total (22% vs 10%; P = 0004), readmission (16% vs 9%; P = 0.03), and nosocomial (6% vs 0.5%; P = 0.01) SBP rates with predominant Gram-negative organisms compared to 1° prophylaxis patients. At 90 days, 1° prophylaxis patients had a higher mortality (35% vs 22%; P = 0.02) and acute kidney injury incidence (48% vs 30%; P = 0.04) compared to 2° prophylaxis patients. DISCUSSION:In this inpatient cirrhosis study, despite prophylaxis, a high proportion of patients developed SBP, which was associated with mortality. Cirrhotic inpatients on 1° prophylaxis had worse outcomes than those on 2° prophylaxis when propensity-matched for the MELD score and serum albumin during the index admission and 90-day follow-up.

Project description:IntroductionQuinolone prophylaxis is recommended for patients with advanced cirrhosis at high risk of spontaneous bacterial peritonitis (SBP) or with prior SBP. Yet, the impact of long-term antibiotic prophylaxis on the microbiome of these patients is poorly characterized.MethodsPatients with liver cirrhosis receiving long-term quinolone prophylaxis to prevent SBP were prospectively included and sputum and stool samples were obtained at baseline, 1, 4 and 12 weeks thereafter. Both bacterial DNA and RNA were assessed with 16S rRNA sequencing. Relative abundance, alpha and beta diversity were calculated and correlated with clinical outcome.ResultsOverall, 35 stool and 19 sputum samples were obtained from 11 patients. Two patients died (day 9 and 12) all others were followed for 180 days. Reduction of Shannon diversity and bacterial richness was insignificant after initiation of quinolone prophylaxis (p > 0.05). Gut microbiota were significantly different between patients (p < 0.001) but non-significantly altered between the different time points before and after initiation of antibiotic prophylaxis (p > 0.05). A high relative abundance of Enterobacteriaceae > 20% during quinolone prophylaxis was found in three patients. Specific clinical scenarios (development of secondary infections during antibiotic prophylaxis or the detection of multidrug-resistant Enterobacteriaceae) characterized these patients. Sputum microbiota were not significantly altered in individuals during prophylaxis.ConclusionThe present exploratory study with small sample size showed that inter-individual differences in diversity of gut microbiota were high at baseline, yet quinolone prophylaxis had only a moderate impact. High relative abundances of Enterobacteriaceae during follow-up might indicate failure of or non-adherence to quinolone prophylaxis. However, our results may not be clinically significant given the limitations of the study and therefore future studies are needed to further investigate this phenomenon.

Project description:Background & aimsBacterial infections, in particular a spontaneous bacterial peritonitis (SBP), are a major threat in patients with liver cirrhosis. Recently, it has been shown that the impact on mortality might be underestimated by established risk-scores. Onset of infection was suggested to define a distinct stage of cirrhosis. However, it remains unclear whether all stages of decompensated cirrhosis are equally affected. Moreover, if there is such a distinct stage, it must be determined whether it is reversible after the infection has resolved. In this study we aimed to further analyze the impact of a current as well as a resolved SBP in different stages of decompensated liver cirrhosis.MethodsA number of 579 patients with liver cirrhosis and ascites were included. MELD-score was used to determine the stage of liver disease. Low (<15), intermediate (15-25) and high (>25) MELD-groups were compared. Patients were followed up for 90 days. Primary endpoint was overall mortality. Statistical analyses were performed using the log-rank test, Cox regression and competing risk analysis.ResultsMortality was significantly higher in patients with nosocomial-acquired SBP (nSBP) compared to patients without SBP (p<0.001;HR = 2.05). However, the most prominent difference in mortality was documented in the intermediate MELD-group (nSBP: p = 0.02;HR = 2.10). Importantly, mortality in nSBP patients remained increased even after the initial nSBP episode had resolved (p<0.01;HR = 1.90). Again, this was only significant in those with intermediate MELD-scores (p = 0.02;HR = 2.28). While a current as well as a resolved nSBP were significantly linked to a higher mortality, neither of them did increase the likelihood for liver transplantation.ConclusionsDevelopment of nSBP is independently associated with increased mortality supporting the concept of a distinct status of cirrhosis. Importantly, the prognosis remains unfavorable even after resolution of nSBP. This could be particularly relevant for patients with intermediate MELD-scores, who have limited chances for a donor liver.

Project description:BACKGROUND AND AIM:The aim of this study was to assess the impact of proton pump inhibitor (PPI) intake on the development of spontaneous bacterial peritonitis (SBP) or other infections, as well as on mortality, in a thoroughly documented cohort of patients with cirrhosis and ascites. PATIENTS AND METHODS:We performed a retrospective analysis of follow-up data from 607 consecutive patients with cirrhosis undergoing their first paracentesis at a tertiary center. A binary logistic regression model investigating the association between PPI intake and SBP at the first paracentesis was calculated. Competing risk analyses and Cox models were used to investigate the effect of PPIs on the cumulative incidence of SBP or other infections and transplant-free survival, respectively. Adjustments were made for age, hepatocellular carcinoma, history of variceal bleeding, varices and model of end-stage liver disease score. RESULTS:Eighty-six percent of patients were receiving PPIs. After adjusting for potential confounding factors, PPI intake was neither associated with increased SBP prevalence at the first paracentesis (odds ratio (OR):1.11,95% confidence interval (95%CI):0.6-2.06; P = 0.731) nor cumulative incidence of SBP (subdistribution hazard ratio (SHR): 1.38; 95%CI:0.63-3.01; P = 0.42) and SBP or other infections (SHR:1.71; 95%CI:0.85-3.44; P = 0.13) during follow-up. Moreover, PPI intake had no impact on transplant-free survival in both the overall cohort (hazard ratio (HR):0.973,95%CI:0.719-1.317; P = 0.859) as well as in the subgroups of patients without SBP (HR:1.01,95%CI:0.72-1.42; P = 0.971) and without SBP or other infections at the first paracentesis (HR:0.944,95%CI:0.668-1.334; P = 0.742). CONCLUSIONS:The proportion of cirrhotic patients with PPI intake was higher than in previous reports, suggesting that PPI indications were interpreted liberally. In our cohort with a particularly high prevalence of PPI intake, we observed no association between PPIs and SBP or other infections, as well as mortality. Thus, the severity of liver disease and other factors, rather than PPI treatment per se may predispose for infectious complications.
