A French national survey on the use of antibiotic prophylaxis in cirrhotic patients

International survey among hepatologists and pulmonologists on the hepatic hydrothorax: plea for recommendations

BACKGROUND

The Hepatic hydrothorax is a pleural effusion related to portal hypertension; its diagnosis and therapeutic management may be difficult. The aims of this article are which follows: To gather the practices of hepatogastroenterologists or pulmonologists practitioners regarding the diagnosis and management of the hepatic hydrothorax.

METHODS

Practitioners from 13 French- speaking countries were invited to answer an online questionnaire on the hepatic hydrothorax diagnosis and its management.

RESULTS

Five hundred twenty-eight practitioners (80% from France) responded to this survey. 75% were hepatogastroenterologists, 20% pulmonologists and the remaining 5% belonged to other specialities. The Hepatic hydrothorax can be located on the left lung for 64% of the responders (66% hepatogastroenterologists vs 57% pulmonologists; p = 0.25); The Hepatic hydrothorax can exist in the absence of clinical ascites for 91% of the responders (93% hepatogastroenterologists vs 88% pulmonologists; p = 0.27). An Ultrasound pleural scanning was systematically performed before a puncture for 43% of the responders (36% hepatogastroenterologists vs 70% pulmonologists; p < 0.001). A chest X-ray was performed before a puncture for 73% of the respondeurs (79% hepatogastroenterologists vs 54% pulmonologists; p < 0.001). In case of a spontaneous bacterial empyema, an albumin infusion was used by 73% hepatogastroenterologists and 20% pulmonologists (p < 0.001). A drain was used by 37% of the responders (37% hepatogastroenterologists vs 31% pulmonologists; p = 0.26).An Indwelling pleural catheter was used by 50% pulmonologists and 22% hepatogastroenterologists (p < 0.01). TIPS was recommended by 78% of the responders (85% hepatogastroenterologists vs 52% pulmonologists; p < 0.001) and a liver transplantation, by 76% of the responders (86% hepatogastroenterologists vs 44% pulmonologists; p < 0.001).

CONCLUSIONS

The results of this large study provide important data on practices of French speaking hepatogastroenterologists and pulmonologists; it appears that recommendations are warranted.

Antibiotic Prophylaxis for Upper Gastrointestinal Bleed in Liver Cirrhosis; Less May Be More

INTRODUCTION

Administration of antibiotics in patients with cirrhosis and upper gastrointestinal bleeding has been shown to improve outcomes. Little is known regarding optimum duration of prophylactic antibiotics. Seven days of antibiotics are generally recommended but very few studies have compared antibiotic duration to clinical outcomes in current available scientific literature. The goal of our study was to study the effect of shorter antibiotic duration on patient outcomes.

METHODS

We conducted a retrospective cohort study of patients with cirrhosis presenting with upper GI bleeding at our institute from 2010 to 2018. Patients were divided into three cohorts based on duration of antibiotic administration for prophylaxis: 1-3 days of antibiotics, 4-6 days of antibiotics and 7 days or more of antibiotics. Rates of infection diagnosis within 30 days, rebleeding, and mortality were compared between the three groups with Chi square, Fisher Exact and Kruskall-Wallace tests. Multivariable analysis was conducted to evaluate independent risk factors for infection.

RESULTS

Medical charts of 980 patients with cirrhosis and upper GI bleeding during the study period were reviewed. A total of 303 with upper gastrointestinal bleeding were included in the final sample, of these 243 patients received antibiotics for prophylaxis and were included for analysis. Seventy-seven patients received antibiotic therapy for 3 days or less, 69 patients for 4-6 days, and 97 patients longer than 6 days. The three groups were well matched in demographic and clinical variables. Twenty-seven patients developed infections within 30 days of bleeding. MELD-Na score at presentation and presence of ascites were associated with infection within 30 days. Rates of infection were not statistically different between the three antibiotic groups (p = 0.78). In the thirty days following the GI bleed, pneumonia was the most diagnosed infection (eleven patients) followed by urinary tract infections (eight patients). Four patients developed spontaneous bacterial peritonitis and three were diagnosed with bacteremia. There was no difference in time to infection (Kruskall Wallace test p = 0.75), early re-bleeding (p = 0.81), late re-bleeding (p = 0.37) and in-hospital mortality (p = 0.94) in the three groups. Six patients in the cohort developed C. Difficile infection; no patient in the short antibiotic group developed C. Difficile infection.

CONCLUSION

Short course of antibiotics for prophylaxis (3 days) appears safe and adequate for prophylaxis in patients with cirrhosis with upper gastrointestinal bleeding if there is no active infection.

Antibiotic prophylaxis in patients with cirrhosis: Current evidence for clinical practice

Patients with cirrhosis show an increased susceptibility to infection due to disease-related immune-dysfunction. Bacterial infection therefore represents a common, often detrimental event in patients with advanced liver disease, since it can worsen portal hypertension and impair the function of hepatic and extra-hepatic organs. Among pharmacological strategies to prevent infection, antibiotic prophylaxis remains the first-choice, especially in high-risk groups, such as patients with acute variceal bleeding, low ascitic fluid proteins, and prior episodes of spontaneous bacterial peritonitis. Nevertheless, antibiotic prophylaxis has to deal with the changing bacterial epidemiology in cirrhosis, with increased rates of gram-positive bacteria and multidrug resistant rods, warnings about quinolones-related side effects, and low prescription adherence. Short-term antibiotic prophylaxis is applied in many other settings during hospitalization, such as before interventional or surgical procedures, but often without knowledge of local bacterial epidemiology and without strict adherence to antimicrobial stewardship. This paper offers a detailed overview on the application of antibiotic prophylaxis in cirrhosis, according to the current evidence.

Transferable Mechanisms of Quinolone Resistance from 1998 Onward

While the description of resistance to quinolones is almost as old as these antimicrobial agents themselves, transferable mechanisms of quinolone resistance (TMQR) remained absent from the scenario for more than 36 years, appearing first as sporadic events and afterward as epidemics. In 1998, the first TMQR was soundly described, that is, QnrA. The presence of QnrA was almost anecdotal for years, but in the middle of the first decade of the 21st century, there was an explosion of TMQR descriptions, which definitively changed the epidemiology of quinolone resistance. Currently, 3 different clinically relevant mechanisms of quinolone resistance are encoded within mobile elements: (i) target protection, which is mediated by 7 different families of Qnr (QnrA, QnrB, QnrC, QnrD, QnrE, QnrS, and QnrVC), which overall account for more than 100 recognized alleles; (ii) antibiotic efflux, which is mediated by 2 main transferable efflux pumps (QepA and OqxAB), which together account for more than 30 alleles, and a series of other efflux pumps (e.g., QacBIII), which at present have been sporadically described; and (iii) antibiotic modification, which is mediated by the enzymes AAC(6')Ib-cr, from which different alleles have been claimed, as well as CrpP, a newly described phosphorylase.

Albumin Use in Patients With Cirrhosis in France: Results of the "ALBU-LIVE" Survey: A Case for Better EASL Guidelines Diffusion and/or Revision

INTRODUCTION

The use of human albumin for the management of cirrhosis has increased. Recommendations have been published for therapeutic paracentesis (TP), spontaneous bacterial peritonitis (SBP), and type 1 hepatorenal syndrome (HRS). The goal of this survey was to assess the prescription practices of French hepatogastroenterologists.

METHODS

All hepatogastroenterologists were contacted. The questionnaire evaluated (1) the use of albumin in validated indications and (2) the prescription of albumin for nonvalidated clinical situations.

RESULTS

Responses were analyzed from 451 (50.1%) practitioners. The mean age was 40 years (range, 24 to 67 y). Physicians practiced in a university hospital (47.7%) or a general hospital (45.8%). There were 56.7% senior practitioners. Overall 99.6% of the practitioners compensated for TP. Albumin was used by 87.8% of the physicians, with a fixed dose being used by 84.6%. For SBP, 94% of the physicians used albumin concomitantly with antibiotics. The recommended protocol was followed by 56.2% of the practitioners: more often by senior university hospital practitioners than by senior general hospital practitioners (P=0.015). About 66.5% used albumin infusion for the diagnosis of HRS: used more often by senior university hospital practitioners (P=0.0006). Albumin was used concomitantly with vasopressor treatment by 84%; the dose and the duration varied considerably. About 23.5% used albumin for severe bacterial infection, 47.9% for severe hyponatremia, 43.9% for severe hypoalbuminemia, and 65.9% for hydrothorax.

CONCLUSIONS

In this large French survey, albumin is only prescribed in accordance with recommendations for TP. The schedule for SBP is followed by only 56% of the practitioners. The use of albumin for HRS is not adapted to recommendations, which are not well known, suggesting that they should be more diffused.

Management of gastric varices: a French national survey

BACKGROUND AND AIMS

Bleeding from gastric varices is more severe than that from esophageal varices, but its management remains debated. We aimed to determine how French hepatogastroenterologists manage cirrhotic patients with gastric varices.

METHODS

Hepatogastroenterologists (n=1163) working in general or university hospitals received a self-administered questionnaire.

RESULTS

Overall, 155 hepatogastroenterologists (13.3%) from 112 centers (33.3%; 39/40 university hospitals, 73/296 general hospitals) answered. Primary prophylaxis was used by 98.1% of hepatogastroenterologists as follows: β-blockers 96.1% (93.8 vs. 97.0%; university vs. general hospitals respectively; P=0.57), glue obliteration 16.9% (17.2 vs. 16.3%; P=0.88), and transjugular intrahepatic portosystemic shunt (TIPS) 8.0% (12.7 vs. 4.6%; P=0.12). To manage bleeding, university hospitals had greater local access to glue obliteration (95.4 vs. 68.2%; P<0.001) and TIPS (78.5 vs. 3.5%; P<0.001). Early TIPS was proposed by 53.6% (72.1 vs. 39.2%; P<0.001). Glue obliteration was performed under general anesthesia (86.1%) using Glubran (43.1%) or Histoacryl (52.9%), and lipiodol (78.8%) with varying degrees of dilution (1 : 10 to 3 : 4). The injected volume per varix varied widely (1-20 ml). Glue obliteration, band ligation, or both were used by, respectively, 64.2, 18.2, and 17.5% of practitioners. Almost all hepatogastroenterologists (98%) performed secondary prophylaxis: β-blockers 74.7% (75.0 vs. 74.4%, university vs. general hospitals; P=0.93), glue obliteration 66.0% (76.9 vs. 57.6%; P=0.013), and TIPS 30.0% (39.1 vs. 23.3%; P=0.037).

CONCLUSION

The management of gastric varices in France is heterogeneous across centers. University hospitals have better access to techniques such as glue obliteration and TIPS. As bleeding from gastric varices has a poor outcome, guidelines should be established to standardize clinical practices and design further studies.

Similar rebleeding rate in 3-day and 7-day intravenous ceftriaxone prophylaxis for patients with acute variceal bleeding

BACKGROUND/PURPOSE

Although prophylactic antibiotics have been recommended for cirrhotic patients with upper gastrointestinal bleeding, the duration of its use remains an inconclusive issue. We designed this study to investigate the duration of antibiotic prophylaxis for cirrhotic patients with acute esophageal variceal bleeding.

METHODS

We enrolled those patients suffering from acute esophageal variceal bleeding and receiving band ligation. They were randomly allocated to two groups to receive prophylactic antibiotics; Group I: receiving intravenous ceftriaxone 500 mg every 12 hours for 3 days, and Group II: same regimen for 7 days. We used rebleeding rate within 14 days as the primary end point and also evaluated the survival rate within 28 days and the amount of transfusion during admission.

RESULTS

There were 38 patients in Group I and 33 patients in Group II that completed the study course for analysis. Overall, there was no significant difference in the baseline characteristics between these two groups. There were three patients both in Group I and Group II who developed rebleeding within 14 days (8% vs. 9%, p > 0.99). There was also no difference between Group I and Group II in transfusion amount (2.71 ± 2.84 units vs. 3.18 ± 4.07, p = 0.839) and survival rate in 28 days (100 vs. 97%, p = 0.465).

CONCLUSION

Our small scale study demonstrated that there was no difference in the rebleeding rate between 3-day and 7-day ceftriaxone prophylaxis for cirrhotic patients with acute esophageal variceal bleeding. There was also no difference in 28 day survival rate between these two groups.

Improved survival of cirrhotic patients with variceal bleeding over the decade 2000-2010

BACKGROUND AND OBJECTIVE

Advances in the management of variceal bleeding (VB) have been highlighted recently. We aimed at assessing whether changing the management of VB has improved the outcome (mortality and rebleeding rates).

METHODS

The files of two cohorts (n=57, 2000-2001 and n=64, 2008-2009) of patients referred to our university center were reviewed after a cross-searching using two coding systems. Data were recorded during the six months after VB.

RESULTS

As compared to 2000-2001, more use of general anesthesia (25.4% vs. 11.1%; P=0.049), band ligations (96.1% vs. 71.4%; P=0.001), octreotide (95.3% vs. 80.7%; P=0.012) and antibiotic prophylaxis (93.8% vs. 82.5%; P=0.09) were performed in 2008-2009, whereas the number of red-cell units transfused during the hospital stay (4.3 ± 3.2 vs. 7.1 ± 5.7; P=0.005) decreased. Surprisingly, more than 60% of patients reached the emergency department from home without medical assistance in both periods. In 2008-2009, patients had more comorbidities and no patients underwent early-TIPS but the 6-week mortality rate (24.6% vs.10.9%; P=0.048) was lower. The 6-week mortality was associated with high MELD score (HR=1.13; 95%CI: 1.08-1.18) and hypovolemic shock (HR=5.36; 95%CI: 1.96-14.67) at admission. In multivariate analysis adjusted on MELD and comorbidities, the 2008-2009 period (HR: 0.42; 95%CI: 0.20-0.87; P=0.02) was associated with a lower 6-month mortality rate.

CONCLUSIONS

Although cirrhotic patients with VB had more comorbidities in 2008-2009 and received no early-TIPS, their prognosis has improved during this last decade concomitantly to a more intensive care and a lower transfusion strategy.

Evolving epidemiology and antimicrobial resistance in spontaneous bacterial peritonitis: a two-year observational study

BACKGROUND

Current recommendations for empirical antimicrobial therapy in spontaneous bacterial peritonitis (SBP) are based on quite old trials. Since microbial epidemiology and the management of patients have changed, whether these recommendations are still appropriate must be confirmed.

METHODS

An observational study that exhaustively collected the clinical and biological data associated with positive ascitic fluid cultures was conducted in four French university hospitals in 2010-2011.

RESULTS

Two hundred and sixty-eight documented positive cultures were observed in 190 cirrhotic patients (median age 61.5 years, 58.5% Child score C). Of these, 57 were classified as confirmed SBP and 140 as confirmed bacterascites. The predominant flora was Gram-positive cocci, whatever the situation (SBP, bacterascites, nosocomial/health-care related or not). Enteroccocci (27.7% E. faecium) were isolated in 24% of the episodes, and in 48% from patients receiving quinolone prophylaxis. E. coli were susceptible to amoxicillin-clavulanate and to third-generation cephalosporins in 62.5% and 89.5% of cases, respectively. No single antibiotic allowed antimicrobial coverage of more than 60%. Only combinations such as amoxicillin + third-generation cephalosporin or cotrimoxazole allowed coverage close to 75-80% in non-nosocomial episodes. Combinations based on broader spectrum antibiotics should be considered for empirical therapy of nosocomial infections.

CONCLUSIONS

Our study confirmed the changing spectrum of pathogens in SBP and bacterascites, and the need for more complex antibiotic strategies than those previously recommended. Our findings also underline the need for new clinical trials conducted in the current epidemiological context.

Risk factors and outcome of bacterial infections in cirrhosis

Viable and non-viable pathological bacterial translocation promote a self-perpetuating circle of dysfunctional immune activation and systemic inflammation facilitating infections and organ failure in advanced cirrhosis. Bacterial infections and sepsis are now recognized as a distinct stage in the natural progression of chronic liver disease as they accelerate organ failure and contribute to the high mortality observed in decompensated cirrhosis. The increasing knowledge of structural, immunological and hemodynamic pathophysiology in advanced cirrhosis has not yet translated into significantly improved outcomes of bacterial infections over the last decades. Therefore, early identification of patients at the highest risk for developing infections and infection-related complications is required to tailor the currently available measures of surveillance, prophylaxis and therapy to the patients in need in order to improve the detrimental outcome of bacterial infections in cirrhosis.
