Hepatitis B Delta: assessment of the knowledge and practices of hepato-gastroenterologists practicing in non-academic settings in France.

BACKGROUND: Data on the management of Hepatitis B-Delta (HB-D) by hepatogastroenterologists (HGs) practicing in nonacademic hospitals or private practices are unknown in France. OBJECTIVE: We aimed to evaluate the knowledge and practices of HGs practicing in nonacademic settings regarding HB-D. METHODS: A Google form document was sent to those HGs from May to September 2021. RESULTS: A total of 130 HGs (mean age, 45 years) have participated in this survey. Among HBsAg-positive patients, Delta infection was sought in only 89% of cases. Liver fibrosis was assessed using FibroScan in 77% of the cases and by liver biopsy in 81% of the cases. A treatment was proposed for patients with >F2 liver fibrosis in 49% of the cases regardless of transaminase levels and for all the patients by 39% of HGs. Responding HGs proposed a treatment using pegylated interferon in 50% of cases, bulevirtide in 45% of cases and a combination of pegylated interferon and bulevirtide in 40.5% of cases. Among the criteria to evaluate the treatment efficacy, a decrease or a normalization of transaminases was retained by 89% of responding HGs, a reduction of liver fibrosis score for 70% of them, an undetectable delta RNA and HBsAg for 55% of them and a 2 log 10 decline in delta viremia for 62% of the cases. CONCLUSION: Hepatitis Delta screening was not systematically performed in HBsAg-positive patients despite the probable awareness and knowledge of the few responders who were able to prescribe treatments of hepatitis delta.

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.

Community-based respondent-driven sampling as a strategy for drug use surveillance in a large French urban area.

BACKGROUND: Understanding drug use and behavior within the PWUD population is crucial to adapt harm reduction and prevention strategies, and provide improved addiction and medical treatment. However, in most countries such as France, the knowledge of drug use behaviors is likely biased as it originates from addiction centers which are attended by only an unknown proportion of PWUD. The objectives of this study were to describe drug use behavior in a population of active PWUD in the urban area of Montpellier, South of France. METHODS: We implemented a community-based respondent-driven sampling survey (RDSS), a validated strategy to obtain a representative sample of a population, to recruit PWUD in the city. Adult individuals reporting frequent psychoactive drug use other than cannabis, with confirmation by urine test, were eligible. Beside HCV and HIV testing, trained peers interviewed participants on their drug consumption and behavior using standardized questionnaires. Fifteen seeds launched the RDSS. RESULTS: During the 11 weeks of the RDSS, 554 actives PWUD were consecutively included. They were mostly men (78.8%), had a median age of 39 years, and only 25.6% had a stable living place. On average, participants consumed 4.7 (± 3.1) different drugs, and 42.6% smoked free-base cocaine. Unexpectedly, heroin and methamphetamine were consumed by 46.8% and 21.5% of participants, respectively. Among the 194 participants injecting drugs, 33% declared sharing their equipment. CONCLUSION: This RDSS highlighted a high consumption of heroin, crack and methamphetamine in this PWUD population. These unexpected results can be explained by low attendance to addiction centers, the source of drug use reports. Despite free care and risk reduction equipment in the city, sharing was very frequent among injectors, challenging the current program of harm reduction.

An observational, prospective, multicenter study on the utilization and effectiveness of elbasvir-grazoprevir treatment association for chronic hepatitis C in France (ZEPHYR study).

Background and Aim: The efficacy and safety profiles of elbasvir-grazoprevir (EBR/GZR) has been established in more than 10 clinical trials. However, the characteristics of patients treated in routine clinical practice may differ. The present study was therefore designed to assess the real-life effectiveness of EBR/GZR therapy in the general population and among subgroups with a high hepatitis C virus (HCV) prevalence in France. Methods: The Zephyr study was designed as a French, multicentre, prospective, observational study on EBR/GZR use and effectiveness in current practice in chronic hepatitis C patients. These results are based on data regarding the adult patients who received at least one dose of EBR/GZR between December 2017 and June 2019 in 67 French hospitals and clinics. Results: Overall, 478 patients were included. The Full Analysis Set corresponded to the 467 patients who met all the inclusion criteria and none of the exclusion criteria. Gender was balanced and the mean age was 55.7 ± 13.3 years. The patients were mainly treatment-naive (89.5%) and infected with Genotype 1b (70.4%). Among the 75 patients with HCV Gt1a genotype, 56% had HCV RNA ≥ 800,000 IU/ml. F3-F4 fibrosis stage involved 24.2% of our population. Our subgroups were distributed among 110 migrants (23.6%), 58 (15.3%) using opioid agonist treatment, including people who inject drugs, 30 (6.8%) with chronic kidney disease Stages 3-5, 9 (1.9%) with an inherited blood disorder, and 4 (0.9%) coinfected with HIV. The remaining 269 (58.7%) were included in the general population subgroup. Overall, sustained virologic response 12 weeks after the end of treatment reached 98.0% and remained consistent among genotype, HCV RNA values, fibrosis stage, and the subgroup of interest. The rate of Alcohol Use Disorders Identification Test-Consumption​​​ and Life Habit questionnaire completion was high at each visit, with data suggesting alcohol consumption decrease and an improvement in quality of life. Conclusions: Using real-world evidence data on a French population representative of HCV patients, we confirmed the results obtained during EBR/GZR development program.

Reaching Hard-to-Reach People Who Use Drugs: A Community-Based Strategy for the Elimination of Hepatitis C.

Background: Elimination of hepatitis C virus (HCV) among people who use drugs (PWUD) remains a challenge even in countries in which HCV care is provided free of cost. We assessed whether an innovative community-based, respondent-driven sampling (RDS) survey, coupled with HCV screening and immediate treatment, could be efficient to detect and cure current PWUD with chronic HCV in a large city of Southern France. Methods: At a community site with peers, PWUD (cannabis not included) were enrolled after confirmation by a urine drug test. Participants were then screened for hepatitis B virus, HCV, and human immunodeficiency virus and benefited from onsite HCV treatment evaluation and prescription. Peer support was provided during treatment, and a systematic visit was scheduled 12 weeks after the end of treatment. The cost of the intervention was estimated. Results: Five hundred fifty-four participants were enrolled. Most were male (78.8%) with a median age of 39 years (interquartile range, 33-46). Cocaine (73.1%) and heroine (46.8%) were the main drugs consumed. Overall, 32.6% of PWUD (N = 181) were HCV seropositive, 49 (27.1%) of which had detectable HCV ribonucleic acid and were thus eligible for treatment. Ten of these patients had severe fibrosis. Hepatitis C virus treatment was initiated for 37 (75.5%) patients, 30 (81.1%) of whom completed their treatment and 27 (73.0%) achieved sustained viral response at week 12. The total cost was 161 euros € per screened patient and 1816€ per patient needing treatment. Conclusions: A community-based RDS survey approach, involving peers, proved efficient and cost-effective to reach and cure PWUD for HCV. This innovative strategy could be key for the final step of HCV elimination. Clinical trial registration. ClinicalTrials.gov, NCT04008927.

Nonalcoholic fatty liver disease: opinions, population served, and management from a sample of French hepato(gastroentero)logists (PERSEPT study).

OBJECTIVE: The three-fold objective of this study was to describe the opinions, the population served, and tools used for the management of nonalcoholic fatty liver disease (NAFLD) by French hepato(gastro)enterologists (HGEs). METHODS: Seventy-five French HGEs working in hospitals or in private practice, who regularly managed patients with NAFLD, completed three questionnaires: one about their opinions about disease management, one on the 10 first patients with NAFLD they saw in February 2020, and the third about the first five patients meeting the 2016 European Association for the Study of the Liver criteria for specialist referral. RESULTS: Management of NAFLD was seen as challenging, complex, time-consuming, and frustrating. Available treatments were considered to be unsatisfactory by most participants. In the whole population studied (671 patients), 41% were obese, 50% overweight, 49% had type 2 diabetes, 61% dyslipidemia, 51% arterial hypertension, 57% nonalcoholic steato-hepatitis (NASH), 37% advanced fibrosis, and 19% cirrhosis. In the subgroup of 313 patients needing specialist referral, the use of liver biopsy was low (30%) and decreasing, whereas vibration-controlled transient elastometry was high (66%) and increasing; blood fibrosis tests were rarely used. NASH was usually diagnosed without liver biopsy. Nutritional counseling was provided to 3/4 patients, physical activity counseling in 1/5. A personalized therapeutic project was defined in less than one-third of patients. Ursodeoxycholic acid and vitamin E were used in a minority of patients. CONCLUSION: The management of NAFLD is not considered satisfactory by French HGE who care for a relatively severe population. Noninvasive assessment of fibrosis and multidisciplinary management should be improved.

Non-invasive diagnosis and follow-up of autoimmune hepatitis.

Autoimmune hepatitis (AIH) is a liver disease characterised by necrotico-inflammatory lesions of hepatocytes, the presence of specific autoantibodies and response to corticosteroid treatment. AIH must be considered in any patient with acute or chronic liver disease. As there is no pathognomonic sign of AIH, the diagnosis is based on a combination of clinical, biological, immunological and histological findings, after excluding other causes of liver disease. The clinical and biological presentation of AIH is variable and AIH can be associated with an autoimmune biliary disease, primary biliary cholangitis or primary sclerosing cholangitis in an overlap syndrome. For these reasons, diagnosis of AIH can be challenging. Even if liver histology remains essential in the diagnosis of AIH, non-invasive tests can be used at different steps of the management of AIH: diagnosis of AIH, notably diagnosis of an overlap syndrome, assessment of severity of AIH, searching for extra-hepatic disease frequently associated to AIH, evaluation of response to therapy, decision of treatment withdrawal. This review aims to provide practical guidelines for the use of non-invasive tests for the diagnosis and the follow-up of AIH.

Non-invasive diagnosis and follow-up of primary biliary cholangitis.

Primary biliary cholangitis (PBC) is a chronic inflammatory disease of the intra-hepatic bile ducts [1]. It is characterised biologically by chronic cholestasis associated with the presence of specific autoantibodies, and histologically by lesions of nonsuppurative destructive cholangitis. If left untreated it can progress to cirrhosis, portal hypertension and liver failure. Diagnosis, staging and follow-up are largely based on non- or minimally-invasive assessment (blood tests, ultrasound, liver stiffness measurement). Histological examination of the liver and upper gastrointestinal endoscopy are sometimes necessary, but their indications remain limited. The purpose of this chapter is to provide the clinicians with what should be known about the non-invasive assessment of PBC and to provide specific recommendations for clinical practice.

Non-invasive diagnosis and follow-up of primary sclerosing cholangitis.

Primary sclerosing cholangitis (PSC) is a rare and chronic cholestatic liver disease of unknown cause commonly associated with inflammatory bowel disease (IBD) and characterized by progressive obliterative fibro-inflammation of the biliary tree. Although the natural course is highly variable, PSC is often progressive, leading to biliary cirrhosis and its complications. In addition, PSC is a condition harbouring broad neoplastic potential with increased susceptibility for the development of both biliary and colon cancer. As in other chronic liver diseases, non-invasive methods play a major role in the diagnosis and monitoring of PSC. MR cholangiography is the key exam for the diagnosis and has replaced diagnostic endoscopic retrograde cholangiopancreatography (ERCP). A strict and standardised protocol for carrying out MR cholangiography is recommended. Liver stiffness measured by FibroScan® correlates with the degree of liver fibrosis, has a prognostic value and should be repeated during follow-up. Invasive methods still play an important role, especially ERCP which is indicated for therapeutic purposes or for endo-biliary sample collection in suspected cholangiocarcinoma (following discussion in a multidisciplinary team meeting) and total colonoscopy which is recommended at the initial diagnosis of any PSC and annually in patients with IBD.

Management of primary biliary cholangitis: results from a large real-life observational study in France and Belgium.

BACKGROUND AND AIMS: To assess the characteristics, care, treatment response, and outcomes of primary biliary cholangitis (PBC) patients recently followed-up by hepato-gastroenterologists in various French and Belgian healthcare settings. METHODS: This retrospective cohort study included patients with PBC who recently visited 79 hepato-gastroenterologists in France and Belgium. Data were collected at the time of diagnosis and at last visit and were compared according to biochemical response (BR) to ursodeoxycholic acid (UDCA) (BR), using Paris I-II criteria, and clinical outcomes. RESULTS: A total of 436 patients (mean age at diagnosis 57 years, 88% females, median follow-up 5.2 years) were included. Liver biopsy, transient elastography, or none of these two procedures were performed at baseline in 216 (50%), 194 (45%), and 107 (25%) patients, respectively. Late-stage disease (histological stage III or IV, or transient elastography ≥9.6 kPa, or bilirubin >17 µM and albumin <35 g/L, or platelets <150.000/µl, or unequivocal signs of portal hypertension or cirrhosis) was reported in 37% of patients. UDCA was taken by 95% of patients (27% had suboptimal dosage). Inadequate BR was observed in 37% of patients. Clinicians overestimated disease control. Liver-related complications occurred in 9% of patients. Bilirubin and albumin independently predicted inadequate BR; advanced disease stage and inadequate BR independently predicted complications. CONCLUSIONS: Recently followed-up French and Belgian patients with PBC had homogeneous management. Late stage at diagnosis and inadequate BR were reported in around 40% of patients. Disease control was frequently overestimated by clinicians. Disease stage and BR were the main prognostic factors.

Subclinical proximal tubulopathy in hepatitis B: The roles of nucleot(s)ide analogue treatment and the hepatitis B virus.

BACKGROUND: The recommended monitoring tools for evaluating nucleot(s)ide analogue renal toxicity, such as estimated glomerular filtration rate (eGFR) and phosphatemia, are late markers of proximal tubulopathy. Multiple early markers are available, but no consensus exists on their use. AIM: To determine the 24 mo prevalence of subclinical proximal tubulopathy (SPT), as defined with early biomarkers, in treated vs untreated hepatitis B virus (HBV)-monoinfected patients. METHODS: A prospective, non-randomized, multicenter study of HBV-monoinfected patients with a low number of renal comorbidities was conducted. The patients were separated into three groups: Naïve, starting entecavir (ETV) treatment, or starting tenofovir disoproxil (TDF) treatment. Data on the early markers of SPT, the eGFR and phosphatemia, were collected quarterly. SPT was defined as a maximal tubular reabsorption of phosphate/eGFR below 0.8 mmoL/L and/or uric acid fractional excretion above 10%. The prevalence and cumulative incidence of SPT at month 24 (M24) were calculated. Quantitative data were analyzed using analyses of variance or Kruskal-Wallis tests, whereas chi-squared or Fisher's exact tests were used to analyze qualitative data. Multivariate analyses were used to adjust for any potential confounding factors. RESULTS: Of the 196 patients analyzed, 138 (84 naïve, 28 starting ETV, and 26 starting TDF) had no SPT at inclusion. At M24, the prevalence of SPT was not statistically different between naïve and either treated group (21.1% vs 30.7%, P < 0.42 and 50.0% vs 30.7%, P = 0.32 for ETV and TDF, respectively); no patient had an eGFR lower than 50 mL/min/1.73 m² or phosphatemia less than 0.48 mmoL/L. In the multivariate analysis, no explanatory variables were identified after adjustment. The cumulative incidence of SPT over 24 mo (25.5%, 13.3%, and 52.9% in the naïve, ETV, and TDF groups, respectively) tended to be higher in the TDF group vs the naïve group (hazard ratio: 2.283, P = 0.05). SPT-free survival at M24 was 57.6%, 68.8%, and 23.5% for the naïve, ETV, and TDF groups, respectively. The median survival time without SPT, evaluated only in the TDF group, was 5.9 mo. CONCLUSION: The prevalence and incidence of SPT was higher in TDF-treated patients compared to naïve patients. SPT in the naïve population suggests that HBV can induce renal tubular toxicity.

Integration of an Addiction Team in a Liver Transplantation Center.

Up to 50% of liver transplantation (LT) recipients with known or clandestine alcohol-use disorder (AUD) before surgery return to alcohol use after LT. However, only severe alcohol relapse, which varies in frequency from 11% to 26% of patients, has an impact on longterm survival and significantly decreases survival rates after 10 years. Therefore, it is crucial to identify patients with the highest risk of severe relapse in order to arrange specific, standardized monitoring by an addiction team before and after LT. The aims of this study were to describe the effects of combined management of AUD on the rate of severe alcohol relapse and to determine the risk factors before LT that predict severe relapse. Patients transplanted between January 2008 and December 2014 who had met with the LT team's addiction specialist were included in the study. Patients who exhibited alcohol-related relapse risk factors received specific addiction follow-up. A total of 235 patients were enrolled in the study. Most of them were men (79%), and the mean age at the time of the LT was 55.7 years. Severe relapse occurred in only 9% of the transplant recipients. Alcohol-related factors of severe relapse were a pretransplant abstinence of 6 months and family, legal, or professional consequences of alcohol consumption, whereas the nonalcohol-related factors were being single and being eligible for a disability pension. In conclusion, the integration of an addiction team in a LT center may be beneficial. The addiction specialist can identify patients at risk of severe relapse in the pretransplantation period and hence arrange for specific follow-up.

Hepatitis C virus infection impacts work productivity and fatigue: An epidemiologic real-life study.

INTRODUCTION AND OBJECTIVE: Hepatitis C virus (HCV) infection and treatment impact the patient's daily life and work productivity. Until recently, treatments were associated with side effects and insufficient virologic and hepatic results. This study evaluated fatigue, work productivity, and treatment modalities in patients with HCV infection. MATERIALS AND METHODS: This cross-sectional, non-interventional, multicenter study was conducted in real-life settings between March and December 2015 at 109 sites in France. RESULTS: Data from 1269 patients were evaluable. The mean patient age was 55.8±12.5 years; 53.3% (676) patients were male. A total of 80.1% (1015) of patients were Caucasian and 62.3% (791) had a genotype 1 infection, 34.2% (433) had at least one comorbidity and 15.6% (198) had ≥1 clinical sign/symptom. Illicit drug use was the main route of HCV transmission and accounted for 36.8% (466) of all infections. Fibrosis stage F0/F1 was reported in 41.4% (525) of patients. A majority of patients (60.4%, 764) had never been treated. In patients previously treated, 85.8% (430) received ribavirin and pegylated interferon and only 13.4% (67) direct-acting antivirals. The mean percent of global impairment due to health was highest (34.8±30.9%) in patients 18-45 years of age. The prevalence of active employed patients with a total fatigue score≥its median value (45/160) was 38.6%. The mean percent work time missed due to health was 9.6±23.6% for working patients of 18-45 years of age and 7.3±21.8% for working patients of 45-65 years of age. The mean overall prevalence of employed patients with impairment due to health issues was 21.8±26.8%. The prevalence of patients with a reduced work activity of ≥50% due to their health status was 32.1%. CONCLUSION: These data reinforce the request for improved disease management in France, allowing patients with HCV infection to increase work productivity, reduce fatigue, and, hopefully, cure their disease.

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.

Major changes in the number and indications of liver biopsy for chronic liver diseases over one decade in France.

AIMS: French clinical practice guidelines on the use of liver biopsy (LB) published in 2002 focused on ultrasound guidance (USG) and ambulatory LB. The aims of this study were as follows: (i) to evaluate the number and indications for LB for chronic liver diseases and (ii) to evaluate LB modalities according to French clinical practice guidelines. Data recorded included the number and indications for LB, procedures, use of USG, and complications. RESULTS: A total of 131 centers participated: 8741 LB were performed versus 12 000 in 1997; ambulatory LB was performed in 48.6% of cases (vs. 27% in 1997; P<0.001). USG during LB was used in 89.7% of the centers, among which 42 (31.8%) used real-time USG (vs. 56 and 22%, respectively, in 1997; P<0.01). The main indications for LB were chronic hepatitis C in 24.6% of cases (vs. 54.1% in 1997; P<0.001), and viral B or B-delta in 15.0% (vs. 5.8%; P<0.001). Severe complications were less frequent at centers with systematical USG during LB than at those without such guidance (P<0.01). CONCLUSION: In this large nationwide study, major trends were as follows: (i) a marked decrease in LB number, related to a decrease in LB for chronic viral hepatitis C; (ii) increased use of USG; and (iii) an increase in the number of ambulatory LB. Severe complications decreased significantly at centers in which USG was systematically applied.

Hepatogastroenterologists' knowledge of inactive carriers and immunotolerant hepatitis B virus patients in France: results of a practice survey.

BACKGROUND: Before the 2012 revision of the EASL guidelines for the management of hepatitis B virus infection, we conducted a survey to determine how French nonacademic hepatogastroenterologists defined inactive hepatitis B virus carriers and immunotolerant patients. METHODS: We asked 680 hepatogastroenterologists to complete a simple survey consisting of 11 multiple-choice questions. RESULTS: The participation rate was 32%. HBeAg positivity was not identified as a key criterion for the diagnosis of immunotolerance by 61.9% of the respondents. A total of 82.5 and 75.9% of the respondents identified repeatedly normal alanine transaminase levels and repeatedly low viremia (<2000 IU/ml), respectively, as relevant criteria for the HBsAg inactive carrier state. The question on the biological monitoring of inactive carriers and immunotolerant patients was answered by 78% of the respondents, 97% of whom considered determinations of α-fetoprotein concentration and viremia every 6 (n=58, 35%) or 12 months (n=105, 63%) to be useful. Overall, 19% of the respondents declared never having treated an immunotolerant patient; 81% reported that they had treated such patients under some circumstances: 73% before immunosuppression or chemotherapy, 54% treated pregnant women in their third trimester when viremia was greater than 7 log IU/ml, 49% treated health professionals to prevent contamination, and 31% before medically assisted procreation. CONCLUSION: The definition of 'inactive carrier state' seems to have been well assimilated, but immunotolerance remains poorly understood. Biological monitoring was frequently carried out for inactive carriers and immunotolerant patients, but the diversity of the responses obtained highlights the lack of clear recommendations for the follow-up of these populations.

Safety and efficacy of combination therapy with peginterferon alfa-2a (40kD) and ribavirin in the outpatient setting: prospective analysis of 197 patients with chronic hepatitis C viral infection.

OBJECTIVES: Combination therapy using peginterferon alfa-2a (40 kD) plus ribavirin achieves viral eradication in nearly 60% of patients with chronic hepatitis C viral infection. However, because of the numerous side effects, use of the combination regimen might be restricted for patients consulting private practitioners specialized in hepatogastroenterology. PATIENTS AND METHOD: Conducted in this specific context, this prospective clinical trial investigated the safety and efficacy of combination therapy in 197 patients. Therapy was given in compliance with the recommendations of the French consensus conference on hepatitis C treatment. RESULTS: Commonly reported adverse effects were noted in 90% of patients, most occurring during the first three months, with a stable prevalence thereafter and resolution after treatment end. The most frequent adverse events were asthenia (35 to 37.5% according to the treatment group pruritus (25 to 26.3%) and flu-like syndrome (19 to 21.7%). A depressive syndrome was reported in 20 to 21% of patients. Grade 4 neutropenia was exceptional and never led to severe infections. At intent-to-treat analysis, the rate of sustained virological response was 54.8% for the entire population. It was 71.1% for patients with genotypes 2 or 3 (mainly treated for 24 weeks) and 44.6% for patients with genotype 1 (all treated 48 weeks). CONCLUSION: The characteristic features of combination therapy observed in the context of private hepatogastroenterology consultations are similar to those observed in randomized clinical trials.

Are drugs a risk factor of post-ERCP pancreatitis?

BACKGROUND: Pancreatitis is the most severe complication of ERCP. The aim of this study was to assess whether the use of potentially pancreatotoxic drugs is a risk factor for post-ERCP pancreatitis. METHODS: Risk factors for post-ERCP pancreatitis and all drugs taken during the month before ERCP were recorded retrospectively in a database. Patients with other causes of acute pancreatitis or chronic pancreatitis were excluded from the analysis. Post-ERCP pancreatitis was defined as abdominal pain and/or vomiting associated with amylase/lipase plasma levels equal to or greater than twice the upper normal value. RESULTS: A total of 173 patients (95 men, 78 women; mean age, 68 [16] years) were included. Post-ERCP pancreatitis occurred in 31 patients (18%). Several risk factors were identified in a multivariate analysis: difficulty in cannulation (p<0.001), endoscopic sphincterotomy (p<0.005), and female gender (p=0.02). Having taken potent pancreatotoxic drugs increased the occurrence of post-ERCP pancreatitis: odds ratio 3.7: 95% confidence intervals [1.1,12.4], p=0.04. CONCLUSIONS: Use of pancreatotoxic drugs before or during ERCP significantly increased the risk of post-ERCP pancreatitis. Thus, discontinuation of the use of such drugs before ERCP seems justified whenever possible.
