RESUMO

BACKGROUND: Patients with cirrhosis are susceptible to develop bacterial infections that trigger acute decompensation (AD) and acute-on-chronic liver failure (ACLF). Infections with multidrug-resistant organisms (MDRO) are associated with deleterious outcome. MDRO colonisation frequently proceeds MDRO infections and antibiotic therapy has been associated with MDRO colonisation. AIM: The aim of the study was to assess the influence of non-antibiotic medication contributing to MDRO colonisation. METHODS: Three hundred twenty-four patients with AD and ACLF admitted to the ICU of Frankfurt University Hospital with MDRO screening were included. Regression models were performed to identify drugs associated with MDRO colonisation. Another cohort (n = 129) from Barcelona was included to validate. A third multi-centre cohort (n = 203) with metagenomic sequencing data of stool was included to detect antibiotic resistance genes. RESULTS: A total of 97 patients (30%) were identified to have MDRO colonisation and 35 of them (11%) developed MDRO infection. Patients with MDRO colonisation had significantly higher risk of MDRO infection than those without (p = 0.0098). Apart from antibiotic therapy (odds ratio (OR) 2.91, 95%-confidence interval (CI) 1.82-4.93, p < 0.0001), terlipressin therapy in the previous 14 days was the only independent covariate associated with MDRO colonisation in both cohorts, the overall (OR 9.47, 95%-CI 2.96-30.23, p < 0.0001) and after propensity score matching (OR 5.30, 95%-CI 1.22-23.03, p = 0.011). In the second cohort, prior terlipressin therapy was a risk factor for MDRO colonisation (OR 2.49, 95% CI 0.911-6.823, p = 0.075) and associated with risk of MDRO infection during follow-up (p = 0.017). The validation cohort demonstrated that antibiotic inactivation genes were significantly associated with terlipressin administration (p = 0.001). CONCLUSIONS: Our study reports an increased risk of MDRO colonisation in patients with AD or ACLF, who recently received terlipressin therapy, while other commonly prescribed non-antibiotic co-medications had negligible influence. Future prospective trials are needed to confirm these results.

RESUMO

BACKGROUND: Non-anastomotic biliary strictures (NAS) are a common cause of morbidity and mortality after liver transplantation. METHODS: All patients with NAS from 2008 to 2016 were retrospectively analyzed. The success rate and overall mortality of an ERCP-based stent program (EBSP) were the primary outcomes. RESULTS: A total of 40 (13.9%) patients with NAS were identified, of which 35 patients were further treated in an EBSP. Furthermore, 16 (46%) patients terminated EBSP successfully, and nine (26%) patients died during the program. All deaths were caused by cholangitis. Of those, one (11%) patient had an extrahepatic stricture, while the other eight patients had either intrahepatic (3, 33%) or combined extra- and intrahepatic strictures (5, 56%). Risk factors of overall mortality were age (p = 0.03), bilirubin (p < 0.0001), alanine transaminase (p = 0.006), and aspartate transaminase (p = 0.0003). The median duration of the stent program was 34 months (ITBL: 36 months; IBL: 10 months), and procedural complications were rare. CONCLUSIONS: EBSP is safe, but lengthy and successful in only about half the patients. Intrahepatic strictures were associated with an increased risk of cholangitis.

RESUMO

BACKGROUND: Secondary sclerosing cholangitis (SSC) is a rare disease with poor prognosis. Cases of SSC have been reported following coronavirus disease 2019 (COVID-SSC). The aim of this study was to compare COVID-SSC to SSC in critically ill patients (SSC-CIP) and to assess factors influencing transplant-free survival. METHODS: In this retrospective, multicenter study involving 127 patients with SSC from 9 tertiary care centers in Germany, COVID-SSC was compared to SSC-CIP and logistic regression analyses were performed investigating factors impacting transplant-free survival. RESULTS: Twenty-four patients had COVID-SSC, 77 patients SSC-CIP, and 26 patients other forms of SSC. COVID-SSC developed after a median of 91 days following COVID-19 diagnosis. All patients had received extensive intensive care treatment (median days of mechanical ventilation, 48). Patients with COVID-SSC and SSC-CIP were comparable in most of the clinical parameters and transplant-free survival was not different from other forms of SSC (P = .443, log-rank test). In the overall cohort, the use of ursodeoxycholic acid (UDCA) (odds ratio [OR], 0.36 [95% confidence interval {CI}, .16-.80], P = .013; log-rank P < .001) and high serum albumin levels (OR, 0.40 [95% CI, .17-.96], P = .040) were independently associated with an increased transplant-free survival, while the presence of liver cirrhosis (OR, 2.52 [95% CI, 1.01-6.25], P = .047) was associated with worse outcome. Multidrug-resistant organism (MDRO) colonization or infection did not impact patients' survival. CONCLUSIONS: COVID-SSC and CIP-SSC share the same clinical phenotype, course of the disease, and risk factors for its development. UDCA may be a promising therapeutic option in SSC, though future prospective trials are needed to confirm our findings.

RESUMO

BACKGROUND: The efficacy of antibiotic prophylaxis to prevent rebleeding or infection after variceal bleeding in patients with liver cirrhosis colonized with multidrug-resistant organisms (MDROs) is unknown. METHODS: In this retrospective study, patients with liver cirrhosis and endoscopically confirmed variceal bleeding who were treated at a tertiary care center in Germany and were screened for MDROs at the time of bleeding were eligible for inclusion. Efficacy of antibiotic prophylaxis was evaluated in patients stratified according to microbiological susceptibility testing. RESULTS: From 97 patients, the majority had decompensated liver cirrhosis (median MELD Score 17) and ACLF was present in half of the patients (47.4%). One third of patients were colonized with MDRO at baseline. De-novo infection until day 10 or the combination of de-novo infection or rebleeding were comparable among both groups (p = 0.696 and p = 0.928, log-rank-test). Risk of de-novo infection or rebleeding was not significantly increased in patients who received antibiotic prophylaxis that did not cover the MDRO found upon baseline screening. Acute-on-chronic liver failure at baseline was the strongest and only independent risk factor that was associated with both outcomes (OR 5.52, 95%-CI 1.48-20.61, p = 0.011 and OR 11.5, 95%-CI 2.70-48.62, p<0.001). Neither MDRO colonization at baseline nor covering all detected MDRO with antibiotic prophylaxis (i.e. "adequate" prophylaxis) impacted transplant-free survival. Again, the presence of ACLF was the strongest independent risk factor associated with mortality (OR 9.85, 95%-CI 3.58-27.12, p<0.0001). CONCLUSION: In this study, MDRO colonization did not increase the risk of rebleeding, infections nor death, even if antibiotic prophylaxis administered did not cover all MDRO detected at MDRO screening. Patients with ACLF had an increased risk of bleeding, infections and death.

RESUMO

BACKGROUND & AIMS: HBV genotype G (HBV/G) is mainly found in co-infections with other HBV genotypes and was identified as an independent risk factor for liver fibrosis. This study aimed to analyse the prevalence of HBV/G co-infections in healthy European HBV carriers and to characterize the crosstalk of HBV/G with other genotypes. METHODS: A total of 560 European HBV carriers were tested via HBV/G-specific PCR for HBV/G co-infections. Quasispecies distribution was analysed via deep sequencing, and the clinical phenotype was characterized regarding qHBsAg-/HBV-DNA levels and frequent mutations. Replicative capacity and expression of HBsAg/core was studied in hepatoma cells co-expressing HBV/G with either HBV/A, HBV/D or HBV/E using bicistronic vectors. RESULTS: Although no HBV/G co-infection was found by routine genotyping PCR, HBV/G was detected by specific PCR in 4%-8% of patients infected with either HBV/A or HBV/E but only infrequently in other genotypes. In contrast to HBV/E, HBV/G was found as the quasispecies major variant in co-infections with HBV/A. No differences in the clinical phenotype were observed for HBV/G co-infections. In vitro RNA and DNA levels were comparable among all genotypes, but expression and release of HBsAg was reduced in co-expression of HBV/G with HBV/E. In co-expression with HBV/A and HBV/E expression of HBV/G-specific core was enhanced while core expression from the corresponding genotype was markedly diminished. CONCLUSIONS: HBV/G co-infections are common in European inactive carriers with HBV/A and HBV/E infection, but sufficient detection depends strongly on the assay. HBV/G regulated core expression might play a critical role for survival of HBV/G in co-infections.

RESUMO

Chronic viral hepatitis is associated with substantial morbidity and mortality worldwide. The aim of our study was to assess the ability of point shear-wave elastography (pSWE) using acoustic radiation force impulse imaging for the prediction of the following liver-related events (LREs): new diagnosis of HCC, liver transplantation, or liver-related death (hepatic decompensation was not included as an LRE). pSWE was performed at study inclusion and compared with liver histology, transient elastography (TE), and serologic biomarkers (aspartate aminotransferase to platelet ratio index, Fibrosis-4, FibroTest). The performance of pSWE and TE to predict LREs was assessed by calculating the area under the receiver operating characteristic curve and a Cox proportional-hazards regression model. A total of 254 patients with a median follow-up of 78 months were included in the study. LRE occurred in 28 patients (11%) during follow-up. In both patients with hepatitis B virus and hepatitis C virus (HCV), pSWE showed significant correlations with noninvasive tests and TE, and median pSWE and TE values were significantly different between patients with LREs and patients without LREs (both P < 0.0001). In patients with HCV, the area under the receiver operating characteristic curve for pSWE and TE to predict LREs were comparable: 0.859 (95% confidence interval [CI], 0.747-0.969) and 0.852 (95% CI, 0.737-0.967) (P = 0.93). In Cox regression analysis, pSWE independently predicted LREs in all patients with HCV (hazard ratio, 17.9; 95% CI, 5.21-61-17; P < 0.0001) and those who later received direct-acting antiviral therapy (hazard ratio, 17.11; 95% CI, 3.88-75.55; P = 0.0002). Conclusion: Our study shows good comparability between pSWE and TE. pSWE is a promising tool for the prediction of LREs in patients with viral hepatitis, particularly those with chronic HCV. Further studies are needed to confirm our data and assess their prognostic value in other liver diseases.

RESUMO

SUMMARY: Wilson's disease (WD) is a rare disorder of copper metabolism usually presenting with variable liver damage and neuropsychiatric symptoms. Here we report a 39-year-old Taiwanese female with late manifestation of WD presenting with gonadotroph, thyreotroph and corticotroph hypopituitarism. Molecular genetic testing revealed compound heterozygosity for two mutations in exons 12 and 14 (c.2828G>A and c.3140A>T). Copper-chelating therapy with D-penicillamine and zinc was initiated along with supplementation of hydrocortisone and L-thyroxine. Hypopituitarism resolved when urinary copper excretion returned to normal levels under copper chelation. This case should raise awareness of pituitary function in WD patients. LEARNING POINTS: Hypopituitarism can complicate Wilson's disease (WD) and endocrinologists should be aware of it when caring for hypopituitary patients. Hepatologists should consider endocrinologic testing for hypopituitarism when WD patients present with symptoms of adrenal insufficiency, thyroid or gonadal dysfunction. Copper-chelating treatment is mandatory and may lead to the recovery of pituitary function in such patients.

RESUMO

In emergency medicine and intensive care the key to control active bleeding - besides definitive therapy (endoscopy, therapeutic angiography or operation) - often is to improve the patients clotting and thrombus formation. Knowledge about routine laboratory testing, their strength and weaknesses as well as indications and dosing of pro-coagulants and blood products remains pivotal in these situations. Achieving hemostasis can be especially challenging in patients with liver cirrhosis, innate or acquired coagulation disorders. This review summarizes the principles of hemostasis diagnostics and management in acute bleeding for gastroenterologists and hepatologists including novel available antidotes and innovative tools for patients with advanced liver disease such as thromboelastometry.

RESUMO

INTRODUCTION: Quinolone 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. METHODS: Patients 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. RESULTS: Overall, 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. CONCLUSION: The 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.

RESUMO

Sphingosine-1-phosphate (S1P) regulates pathophysiological processes, including liver regeneration, vascular tone control, and immune response. In patients with liver cirrhosis, acute deterioration of liver function is associated with high mortality rates. The present study investigated whether serum S1P concentrations are associated with disease severity in patients with chronic liver disease from compensated cirrhosis (CC), acute decompensation (AD), or acute-on-chronic liver failure (ACLF). From August 2013 to October 2017, patients who were admitted to the University Hospital Frankfurt with CC, AD, or ACLF were enrolled in our cirrhosis cohort study. Tandem mass spectrometry was performed on serum samples of 127 patients to assess S1P concentration. Our study comprised 19 patients with CC, 55 with AD, and 51 with ACLF, aged 29 to 76 years. We observed a significant decrease of S1P according to advanced liver injury from CC and AD up to ACLF (P < 0.001). S1P levels further decreased with progression to ACLF grade 3 (P < 0.05), and S1P highly inversely correlated with the Model for End-Stage Liver Disease score (r = -0.508; P < 0.001). In multivariate analysis, S1P remained an independent predictor of 7-day mortality with high diagnostic accuracy (area under the curve, 0.874; P < 0.001). Conclusion: In patients with chronic liver disease, serum S1P levels dramatically decreased with advanced stages of liver disease and were predictive of early mortality. Because S1P is a potent regulator of endothelial integrity and immune response, low S1P levels may significantly influence progressive multiorgan failure. Our data justify further elucidation of the diagnostic and therapeutic role of S1P in ACLF.

RESUMO

INTRODUCTION: With the emergence of multidrug-resistant organisms, the efficacy of antibiotic prophylaxis to prevent spontaneous bacterial peritonitis (SBP) has been debated. The aim of this study was to assess factors impacting effectiveness of SBP prophylaxis. METHODS: We searched PubMed, Embase, and the Cochrane Registry from inception to May 2019 to identify randomized controlled trials of patients with liver cirrhosis that assessed SBP occurrence/recurrence during antibiotic prophylaxis with the common antibiotic agents. Network meta-analysis was performed, pooling data with regard to incidence rate ratios (IRRs) of SBP, death, or extraperitoneal infections. RESULTS: Overall, 1,626 patients in 12 randomized controlled trials were included. During primary prophylaxis, the incidence rate of SBP and death in the norfloxacin-treated patients was 0.117 and 0.438 per patient-year, respectively, and IRRs of placebo vs norfloxacin were significantly higher (IRR 5.35, 95% confidence interval 1.99-14.38, P = 0.0009 for SBP and IRR 2.04, 95% confidence interval 1.20-3.44, P = 0.008 for death). The efficacy of norfloxacin to prevent SBP, but not death, decreased over time (annual percent change from 1992 to 2015 8.2%, P = 0.019), The positive treatment effect was lower in studies including patients with increased ascites protein (P = 0.021) or exceedingly high serum bilirubin (P = 0.012) levels. Norfloxacin was not superior to other antibiotics. The incidence rate of SBP was 2.5-fold higher in patients treated with norfloxacin as secondary compared with primary prophylaxis. No significant differences between treatment designs were observed in secondary prophylaxis. DISCUSSION: Norfloxacin remained superior to placebo in preventing SBP, yet the efficacy to prevent SBP, not death, decreased over time. Further studies to understand this phenomenon are urgently needed.

RESUMO

AIMS: Heart transplantation may represent a particular risk factor for severe coronavirus infectious disease 2019 (COVID-19) due to chronic immunosuppression and frequent comorbidities. We conducted a nation-wide survey of all heart transplant centers in Germany presenting the clinical characteristics of heart transplant recipients with COVID-19 during the first months of the pandemic in Germany. METHODS AND RESULTS: A multicenter survey of all heart transplant centers in Germany evaluating the current status of COVID-19 among adult heart transplant recipients was performed. A total of 21 heart transplant patients with COVID-19 was reported to the transplant centers during the first months of the pandemic in Germany. Mean patient age was 58.6 ± 12.3 years and 81.0% were male. Comorbidities included arterial hypertension (71.4%), dyslipidemia (71.4%), diabetes mellitus (33.3%), chronic kidney failure requiring dialysis (28.6%) and chronic-obstructive lung disease/asthma (19.0%). Most patients received an immunosuppressive drug regimen consisting of a calcineurin inhibitor (71.4%), mycophenolate mofetil (85.7%) and steroids (71.4%). Eight of 21 patients (38.1%) displayed a severe course needing invasive mechanical ventilation. Those patients showed a high mortality (87.5%) which was associated with right ventricular dysfunction (62.5% vs. 7.7%; p = 0.014), arrhythmias (50.0% vs. none; p = 0.012), and thromboembolic events (50.0% vs. none; p = 0.012). Elevated high-sensitivity cardiac troponin T- and N-terminal prohormone of brain natriuretic peptide were significantly associated with the severe form of COVID-19 (p = 0.017 and p < 0.001, respectively). CONCLUSION: Severe course of COVID-19 was frequent in heart transplanted patients. High mortality was associated with right ventricular dysfunction, arrhythmias, thromboembolic events, and markedly elevated cardiac biomarkers.

RESUMO

BACKGROUND: The efficacy of antibiotic prophylaxis to prevent spontaneous bacterial peritonitis (SBP) in patients colonized with multidrug-resistant organisms (MDROs) is unknown. We evaluated the effectiveness of fluoroquinolone-based SBP prophylaxis in an era and area of frequent antibiotic resistance. METHODS: This is a prospective observational study in patients with liver cirrhosis and an indication for fluoroquinolone-based prophylaxis of SBP. Patients were recruited and followed in a large German tertiary reference center with comprehensive microbiological and clinical monitoring performed at baseline and after 30, 60, 90, and 180 days of prophylaxis. RESULTS: Overall, 77 patients received antibiotic prophylaxis for an average of 93 days. Baseline prevalence of colonization with MDROs was high (N = 39, 50.6%). At least one de novo MDRO was detected in 27 patients (35.1%) during antibiotic prophylaxis; 33 patients (42.9%) developed secondary infections, including 14 cases (17.9%) of infections with MDROs, and 13 cases (16.9%) of de novo/recurrent SBP. Thirty patients (39.0%) died during follow-up. Significantly higher risks of SBP development during antibiotic prophylaxis were observed for patients with versus without any apparent MDROs (P = .009), vancomycin-resistant enterococci (P = .008), multidrug-resistant gram-negative bacteria (P = .016), or quinolone-resistant gram-negative bacteria (QR-GNB) (P = .015). In competing risk analysis, QR-GNB were independently associated with prophylaxis failure (hazard ratio, 3.39; P = .045) and infections with QR-GNB were independently associated with death before SBP (subdistribution hazard risk, 6.47; P = .034). CONCLUSIONS: Antibiotic prophylaxis of SBP appears to be less efficient in patients with known MDROs. Regular MDRO screening seems to be useful to tailor treatment of secondary infections and re-evaluate antibiotic prophylaxis in case of selection of quinolone resistance.

RESUMO

Autologous hematopoietic stem cell transplantation (auto-HSCT) provides a potentially curative treatment option for relapsed and refractory lymphomas. Obesity displays an emerging epidemic risk factor for global mortality and is associated with an increased mortality in cancer patients. To date, the impact of obesity on the outcome of lymphoma patients undergoing auto-HSCT is understudied. We conducted a retrospective single-center study assessing 119 lymphoma patients who underwent auto-HSCT. Overall survival (OS) served as the primary endpoint whereas progression free survival (PFS), cumulative incidence of non-relapse related mortality (NRM) and cumulative incidence of relapse were analyzed as secondary endpoints. Obese patients (Body mass index, BMI≥30) had significantly lower OS (45.3% vs. 77.9%; p = 0.005) and PFS (29.8% vs. 67.2%; p<0.001) compared to non-obese patients at 48 months post-transplantation. The cumulative incidence of NRM displayed no significant differences while the cumulative incidence of relapse was significantly increased in patients with BMI≥30 (66.2% vs. 21.5%; p<0.001). Patients with a BMI<25 and overweight patients (BMI 25-30; 76.1% vs. 80.9%; p = 0.585), showed no significant difference in OS, whereas patients with BMI≥30 exhibited significant lower OS when compared to either of both groups (76.1% vs. 45.3%; p = .0.021 and 80.9% vs. 45.3%; p = 0.010). Furthermore, in a multivariate analysis, obesity was identified as an independent risk factor for death (Hazard ratio 2.231; 95% CI 1.024 to 4.860; p = 0.043). Further studies are needed to evaluate the reasons for the higher relapse rate causing higher mortality in obese patients.

RESUMO

BACKGROUND: The COBAS AmpliPrep/COBAS TaqMan assay HCV (CAP/CTM) is widely used in clinical routine for HCV testing. Recently, the new cobas HCV test was established for high throughput testing with minimal operator intervention. As different assays may yield different quantitative/qualitative results that possibly impact treatment decisions, the aim of this study was to externally evaluate the cobas HCV test performance in comparison to CAP/CTM in a clinically relevant setting. METHODS: Serum samples were obtained from 270 patients who received direct acting antiviral therapy with different treatment regimens at two study sites (Hannover and Frankfurt) in 2016. Overall, 1545 samples (baseline, on-treatment and follow-up) were tested in parallel by both assays. RESULTS: The mean difference between cobas HCV and CAP/CTM for the quantification of HCV RNA was 0.008 log10 IU/ml HCV RNA (95% limits of agreement: -0.02-0.036) showing excellent agreement of both assays. With respect to clinical cut offs (HCV RNA detectable vs. target not detected and HCV RNA above the lower limit of quantification (LLOQ) vs.

RESUMO

BACKGROUND & AIMS: Curing hepatitis C virus (HCV) infection reduces the risk of hepatocellular carcinoma (HCC) development, yet HCC occurs despite sustained virologic response (SVR) in 2%-8% of cirrhotic patients. Sphingolipids (SLs) have been identified as new biomarkers of chronic liver disease and HCC. The aim of this study was to evaluate serum SLs as diagnostic HCC biomarkers in patients with HCV-associated cirrhosis at SVR12. METHODS: From 2014 to 2016, 166 patients with HCV-cirrhosis and SVR were recruited and SL profiles were measured at baseline and 12 weeks after completion of direct-acting antiviral (DAA) therapy. All patients received HCC surveillance in line with current guideline recommendations. Minimum follow-up period comprised 6 months. RESULTS: Our study included 130 (78%) patients without history of HCC, 25 (15%) with history of HCC prior DAA therapy and 11 (7%) patients with de novo HCC after FU12. In those with upcoming de novo HCC serum C24DHC (P = 0.006), C24:1DHC (P = 0.048) and C16Cer (P = 0.011) were significantly upregulated at FU12, but not AFP (P = 0.138). Contemporaneous ultrasound did not visualize HCC, at this time. C16Cer stayed sole independent predictor with high diagnostic accuracy of AFP-positive (AUC = 0.741) and -negative (AUC = 0.766) HCC development. Serum SL parameters decreased from baseline to SVR12. CONCLUSIONS: C24DHC, C24:1DHC and especially C16Cer were superior to AFP in early detection of AFP-positive and -negative de novo HCC development. We observed significant SL profile changes upon SVR. SLs may play a role in non-invasive HCC surveillance and hepatocarcinogenesis.

RESUMO

BACKGROUND&AIMS: Since the introduction of direct-acting antivirals (DAAs) several studies have reported high efficacy and safety in Hepatitis C infected patients, even in those earlier considered difficult-to-treat. We aimed to assess the efficacy and safety of DAA therapy in elderly patients. METHODS: The PubMed MEDLINE, Embase and Cochrane databases were searched through July 2018. Two independent researchers extracted data and assessed the quality and risk of bias. Risk ratios (RRs) were pooled using random effects models. The primary outcome was efficacy of DAA therapy assessed by the RR for non-sustained virologic response (SVR) among patients aged <65 vs ≥65 years. RESULTS: Overall, we identified 63 studies including 34 082 patients treated with different DAAs. Risk for non-SVR was comparable in patients <65 and ≥65 years of age (RR 1.00, 95% CI 0.86-1.15; P = 0.979) and even lower in a subgroup analysis of cirrhotic patients ≥65 years of age (RR 0.59, 95% CI 0.35-0.99, P = 0.044). Risk for non-SVR was similar between age groups in all other subgroup analyses. Elderly patients had a significantly increased risk of adverse events (AEs) (RR 1.30, 95% CI 1.11-1.52, P = 0.001), but not for serious adverse events (P = 0.43) or treatment discontinuation (P = 0.15). Risk for anaemia if treated with additional ribavirin was 2.84 (95% CI 1.73-4.66, P < 0.001) in elderly patients compared to patients <65 years. CONCLUSION: Our results show that DAAs are highly effective and safe in elderly patients. Ribavirin should be avoided in the elderly as more AEs and particularly anaemia is observed. Further cost-effectiveness analyses are needed to evaluate the socio-economic benefit of treating elderly people without advanced liver disease.

RESUMO

BACKGROUND: Patients with chronic hepatitis C virus (HCV) infection and active or previous hepatitis B virus (HBV) are at risk of HBV reactivation (HBV-R) during direct-acting antiviral (DAA) therapy. Recent reports suggest that HBV-R may even occur several months after completion of DAA therapy. The aim of this study was to assess the risk of HBV-R in patients with resolved HBV after successful DAA therapy during long-term follow-up (FU). METHODS: Among 848 patients treated for chronic HCV, all patients with resolved HBV and long-term FU data were eligible for inclusion. Patients were HBV DNA/hepatitis B surface antigen (HBsAg)-negative at the end of therapy (EOT) and were followed for up to 52 weeks thereafter. Patients underwent regular alanine transaminase (ALT) testing, and additional HBV DNA/HBsAg testing was performed at FU week 12, end of FU, and in case of an ALT increase above the upper limit of normal (>ULN). RESULTS: A total of 108 patients were followed up for a mean (range) of 41.5 (24-52) weeks after EOT. None of the patients experienced reverse HBsAg seroconversion or reappearance of HBV DNA. One patient received a liver transplantation; 1 patient was diagnosed with de novo hepatocellular carcinoma, and 2 patients died. Eighteen patients (16.7%) had increased ALT levels (grade 0/1). Of those, the majority were male (72.2%) and significantly more patients had cirrhosis (66.7% vs 36.2%, P = .015) or received ribavirin as part of their treatment regimen (86.7% vs 46.8%, P = .041). None of these were associated with HBV-R. CONCLUSIONS: Our results indicate that the risk of HBV-R in patients with resolved HBV treated with DAAs for HCV is low during long-term follow-up.

RESUMO

Direct acting antivirals (DAA) have revolutionized the treatment of hepatitis C virus (HCV). Sustained virological response rates of nearly 100% have become common in the general population. However, physicians face the growing problem of managing HCV in patients with the complications of cirrhosis, eg hepatic decompensation or hepatocellular carcinoma (HCC). Safety and efficacy remain a clinical challenge in these difficult-to-treat patients. This review focuses on the current state of knowledge and treatment regimens in patients with decompensated cirrhosis as well as the potential risk of the development of HCC following DAA therapy.

RESUMO

BACKGROUND: Direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection might pose a risk for hepatitis B virus (HBV) reactivation in patients coinfected with chronic or resolved HBV infection. The need for HBV antiviral prophylaxis during DAA treatment remains controversial. We aimed to analyse the absolute risk of HBV reactivation in patients with active or resolved HBV infection treated with DAAs for HCV infection. METHODS: For this systematic review and meta-analysis, we searched PubMed, Ovid MEDLINE, the Cochrane Central Register of Controlled Trials, and Web of Science from Oct 1, 2010, to Sept 30, 2017, to identify studies of patients with chronic or resolved HBV infection at baseline treated with DAAs for chronic HCV infection. Conference proceedings, abstract books, and references from relevant reviews were also examined for potential studies. Two independent researchers extracted data and assessed quality and risk of bias. Data were pooled by use of random-effects models. The primary outcome was HBV reactivation defined by standardised nomenclature. This study is registered with PROSPERO, number CRD42017065882. FINDINGS: We identified 17 observational studies involving 1621 patients with chronic (n=242) or resolved (n=1379) HBV infection treated with different DAAs. The pooled proportion of patients who had HBV reactivation was 24% (95% CI 19-30) in patients with chronic HBV infection and 1·4% (0·8-2·4) in those with resolved HBV infection. In patients with chronic HBV infection, the pooled proportion of patients with HBV-reactivation-related hepatitis was 9% (95% CI 5-16) and the relative risk (RR) of HBV-reactivation-related hepatitis was significantly lower in patients with HBV DNA below the lower limit of quantification at baseline than in those with quantifiable HBV DNA (RR 0·17, 95% CI 0·06-0·50; p=0·0011). Three major clinical events related to HBV reactivation in patients with chronic HBV infection were reported (one patient had liver decompensation and two had liver failure, one of whom required liver transplantation). In patients with resolved HBV infection, no HBV-reactivation-related hepatitis was reported. INTERPRETATION: HBV reactivation occurs frequently in patients with chronic HBV and HCV coinfection receiving DAA therapy but is rare among patients with resolved HBV infection. Use of antiviral prophylaxis might be warranted in patients who test positive for hepatitis B surface antigen (HBsAg), particularly those with quantifiable HBV DNA. FUNDING: None.
