Abstract: Chronic infection perturbs immune homeostasis. While prior studies have reported dysregulation of effector and memory cells, little is known about the effects on naïve T cell populations. We performed a cross-sectional study of chronic hepatitis C (cHCV) patients using tetramer-associated magnetic enrichment to study antigen-specific inexperienced CD8+ T cells (i.e., tumor or unrelated virus-specific populations in tumor-free and sero-negative individuals). cHCV showed normal precursor frequencies, but increased proportions of memory-phenotype inexperienced cells, as compared to healthy donors or cured HCV patients. These observations could be explained by low surface expression of CD5, a negative regulator of TCR signaling. Accordingly, we demonstrated TCR hyperactivation and generation of potent CD8+ T cell responses from the altered T cell repertoire of cHCV patients. In sum, we provide the first evidence that naïve CD8+ T cells are dysregulated during cHCV infection, and establish a new mechanism of immune perturbation secondary to chronic infection.

Subjects: Medicine, Science
Abstract: BACKGROUND:Human genetic factors influence the outcome of pegylated interferon and ribavirin hepatitis C therapy. We explored the role of IL28B, APOH and ITPA SNPs on the outcomes of triple therapy including telaprevir or boceprevir in patients with compensated cirrhosis chronically infected with HCV-1. PATIENTS AND METHODS:A total of 256 HCV-1 Caucasian treatment-experienced patients with compensated cirrhosis from the ANRS CO20-CUPIC cohort were genotyped for a total of 10 candidate SNPs in IL28B (rs12979860 and rs368234815), APOH (rs8178822, rs12944940, rs10048158, rs52797880, rs1801689 and rs1801690) and ITPA (rs1127354 and rs7270101). We tested the association of IL28B and APOH SNPs with sustained virological response and of ITPA SNPs with anemia related phenotypes by means of logistic regression assuming an additive genetic model. RESULTS:None of the six APOH SNPs were associated with sustained virological response. The favorable alleles of the IL28B SNPs rs12979860 and rs368234815 were associated with sustained virological response (rs12979860: OR = 2.35[1.50-3.70], P = 2x10(-4)). Refined analysis showed that the effect of IL28B SNPs on sustained virological response was restricted to prior PegIFN/RBV relapse (OR = 3.80[1.82-8.92], P = 8x10(-4)). We also confirmed the association between ITPA low activity alleles and protection against early hemoglobin decline in triple therapy (P = 2x10(-5)). CONCLUSION:Our results suggest that the screening of rs12979860 may remain interesting for decision making in prior relapse HCV-1 Caucasian patients with compensated cirrhosis eligible for a telaprevir- or boceprevir-based therapy.

Abstract: International audience; Ascites is the most common complication of cirrhosis, which develops in 5%-10% of patients per year. Its management is based on symptomatic measures including restriction of sodium intake, diuretics and paracentesis. Underlying liver disease must always be treated and may improve ascites. In some patients, ascites is not controlled by medical therapies and has a major impact on quality of life and survival. TIPS placement and liver transplantation must therefore be discussed. More recently, repeated albumin infusions and Alfapump® have emerged as new therapies in ascites. In this review, the current data on these different options are analysed and an algorithm to help the physician make clinical decisions is suggested.

Abstract: Background Salvage transjugular intrahepatic portosystemic shunts (TIPS) are associated with poor prognosis, especially in patients with Child-Pugh C cirrhosis. Since preemptive TIPS improved prophylaxis of variceal bleeding in those patients, recourse to salvage TIPS may now affect patients with a better prognosis. Aim To assess the impact of the preemptive TIPS policy on outcomes after salvage TIPS placement. Methods We conducted a retrospective monocentric study on cirrhotic patients undergoing salvage TIPS with polytetrafluoroethylene-covered stents from 2002 to 2017 (period 1 until February 2011; period 2 after the preemptive TIPS policy in March 2011). The primary endpoint was one-year transplant-free survival. Results We included 106 patients (period 1/2 = 53/53 patients, male gender 82%, age 54 ± 9 years, alcoholic cirrhosis 70%, Child-Pugh score B/C 94%). One-year transplant-free survival was 46.0% during period 1 compared to 40.2% during period 2 (p = 0.65). Amongst 61 patients with history of variceal bleeding, 32 (52.5%) had an inadequate secondary prophylaxis, including 19 (59.4%) with a previous indication of preemptive TIPS. One-year transplant-free survival was 33.2% if inadequate secondary prophylaxis vs 65.2% if adequate (p = 0.008). Independent factors associated with survival were a lower Child-Pugh or MELD score, infection, failure to control bleeding, and hepatic encephalopathy after TIPS. Conclusion Prognosis after salvage TIPS remained poor in our series. Optimizing secondary prophylaxis, including preemptive TIPS placement, should be the main concern to improve prognosis.

Abstract: Gastrointestinal variceal bleeding (VB) is a frequent and severe complication in cirrhosis. Despite improvement in the last decades in the management of VB, the 6-week mortality after bleeding still ranges from 10 to 20%. Here, we review an up-to-date in the global management of VB. The endoscopic hemostatic treatment relies on band ligation for esophageal variceal bleeding and tissue adhesive injection for gastric variceal bleeding. In case of refractory bleeding, self-expanding metal stents or balloon tamponade can both be used as bridge to specific treatment. The use of covered TIPS provided a new step in the management of VB in severe patients, so-called “early-TIPS” in the setting of secondary prophylaxis or in all patients with refractory bleeding. The global management of patients with VB should include volume resuscitation, blood transfusion, and prevention of complications such as renal failure+/-sepsis+/-liver encephalopathy, as they drive the prognosis. Therefore, the rapid control of gastrointestinal bleeding and subsequent organ complications should be performed in specific intensive care units.

Abstract: Introduction Erectile dysfunction (ED) is common in patients with chronic diseases. It is evaluated using the International Index of Erectile Function (IIEF5) questionnaire. The relationship between ED and cirrhosis is complex. The aims of our study were (1) to assess the prevalence of ED in cirrhosis and (2) to evaluate factors associated with ED, with a special focus on minimal hepatic encephalopathy (MHE). Methods We performed a prospective, observational study. Patients with cirrhosis were invited to complete the IIEF5 questionnaire. The exclusion criteria were clinical hepatic encephalopathy (HE) and dementia. MHE was evaluated by the psychometric hepatic encephalopathy test score (PHES) and the critical flicker frequency (CFF). Results Between April 2016 and April 2017, 87 patients were included (age: 55 [51–57] years, Child–Pugh score: 8 [7–9], MELD score: 13 [11–16]. Minimal HE was diagnosed in 33% of the patients according to the PHES and in 44% of the patients according to the CFF. ED was diagnosed in 74/87 patients (85%) when compared to 12.5% in healthy controls (p Conclusion ED should be systematically screened in cirrhotics, especially in patients with MHE.

Abstract: International audience; Despite the astonishing progress in treating chronic hepatitis C virus (HCV) infection with direct-acting antiviral agents, liver fibrosis remains a major health concern in HCV infected patients, in particular due to the treatment cost and insufficient HCV screening in many countries. Only a fraction of patients with chronic HCV infection develop liver fibrosis. While there is evidence that host genetic factors are involved in the development of liver fibrosis, the common variants identified so far, in particular by genome-wide association studies, were found to have limited effects. Here, we conducted an exome association study in 88 highly selected HCV-infected patients with and without fibrosis. A strategy focusing on TGF-β pathway genes revealed an enrichment in rare variants of the endoglin gene (ENG) in fibrosis patients. Replication studies in additional cohorts (617 patients) identified one specific ENG variant, Thr5Met, with an overall odds ratio for fibrosis development in carriers of 3.04 (1.39-6.69). Our results suggest that endoglin, a key player in TGF-β signaling, is involved in HCV-related liver fibrogenesis.

Abstract: International audience; Salvage transjugular intrahepatic portosystemic shunt (TIPSS) has proven its efficacy to treat refractory variceal bleeding for patients with cirrhosis. However, this procedure is associated with very poor outcomes. As it is used as a last resort to treat a severe complication of cirrhosis, it seems essential to improve our practice, with the aim of optimizing management of those patients. Somehow, many questions are still unsolved: which stents should be used? Should a concomitant embolization be systematically considered? Is there any alternative therapeutic in case of recurrent bleeding despite TIPSS? What are the long-term outcomes on survival, liver transplantation, and hepatic encephalopathy after salvage TIPSS? Is this procedure futile in some patients? Is prognosis with salvage TIPSS nowadays as bad as earlier, despite the improvement of prophylaxis for variceal bleeding? The aim of this review is to summarize those data and to identify the lacking ones to guide further research on salvage TIPSS.

Abstract: The aim of the present study was to determine the prevalence of long-term mucocele development after functional endoscopic sinus surgery (FESS) for nasal polyposis, to search for a statistical relationship with preoperative variables and to analyze the management of this complication. A retrospective analysis of 153 patients who underwent FESS for nasal polyposis, with a minimum of 7 years of follow-up, was performed. Mucocele diagnosis was based on regular clinical and radiologic evaluation. Univariate and multivariate statistical analysis was performed. The postoperative mucocele rate was 13.1% (20 patients). The mean delay between surgery and mucocele diagnosis was 6.25 years. A high preoperative Lund-Mackay score (>19) was a risk factor for postoperative mucocele (p = 0.04). Asthma and aspirin intolerance did not increase the risk of this complication. Endoscopic marsupialization of mucoceles was successful in 19 patients, with only one recurrent frontal mucocele. One patient required external approaches for two frontal mucoceles. In conclusion, mucocele risk after FESS for nasal polyposis is significant, especially in case of a high preoperative Lund-Mackay score (>19). Long-term clinical follow-up is recommended, imaging being prescribed based on symptoms or abnormal findings on clinical examination. Endoscopic marsupialization is very effective, but frontal mucoceles are more likely to recur.

Abstract: Chronic hepatitis B virus (HBV) infection is a major public health problem. It concerns more than 240 million people over the world. Natural HBV history leads to hepatocellular carcinoma (HCC), developed on cirrhotic liver and/or by direct viral cacinogenesis. HCC incidence is estimated between 0,2 and 1% per year. The risk of HCC development showed a positive correlation with the level of HBV DNA in the sera. This virosuppression, obtained with interferon or analogs, can reduce the incidence of HCC development during chronic HBV infection. In case of HCC curative surgery, sustained virological response showed a protective effect on recurrence development. Guidelines suggest to treat every cirrhotic or highly replicative patients, and to screen every six months chronic HBs antigen carrier to prevent HCC development.

Abstract: International audience; BACKGROUND & AIMS:Chronic infection with HCV remains a public health problem with approximately 150 million people infected worldwide. HCV intersects with lipid metabolism for replication and entry; and plasma concentrations of apolipoproteins have been identified as predictors for response to therapy. Herein, we conducted a screen of plasma proteins, including all apolipoproteins, to identify correlates of response to pegylated-interferon/ribavirin (PR) and HCV non-structural protein 3 (NS3) inhibitors (i.e., telaprevir/boceprevir) therapy in treatment-experienced cirrhotic patients from the ANRS CUPIC cohort.METHODS:We analysed 220 baseline plasma protein concentrations in 189 patients using Luminex technology and analyzed results.RESULTS:We identified baseline levels of apolipoprotein H (apoH) as a surrogate marker for sustained virological response (SVR). Notably, increased plasma concentration of apoH, used in combination with known clinical parameters, established a robust model with improved classification of patients as likely to achieve SVR (AUC = 0.77, Se = 66%, Sp = 72%, NRI = 39%). Moreover, we provide mechanistic information that indicates a previously unidentified role for apoH during viral entry. Using a human liver slices HCV infection model, we demonstrate that apoH limits replication.CONCLUSION:These data support testing of new biomarker strategies for the management of cirrhotic HCV patients and expand our understanding of how apoH may intersect with HCV infection

Abstract: Objective To determine the frontal sinus revision rate after nasal polyposis (NP) surgery including frontal recess clearance (FRC) and middle turbinectomy (MT), to search for predictive factors and to analyse surgical management. Methods Longitudinal analysis of 153 patients who consecutively underwent bilateral sphenoethmoidectomy with FRC and MT for NP with a minimum follow-up of 7 years. Decision of revision surgery was made in case of medically refractory chronic frontal sinusitis or frontal mucocele. Univariate and multivariate analysis incorporating clinical and radiological variables were performed. Results The frontal sinus revision rate was 6.5% (10/153). The mean time between the initial procedure and revision surgery was 3 years, 10 months. Osteitis around the frontal sinus outflow tract (FSOT) was associated with a higher risk of frontal sinus revision surgery (p = 0.01). Asthma and aspirin intolerance did not increase the risk, as well as frontal sinus ostium diameter or residual frontoethmoid cells. Among revised patients, 60% required multiple procedures and 70% required frontal sinus ostium enlargement. Conclusions Our long-term study reports that NP surgery including FRC and MT is associated with a low frontal sinus revision rate (6.5%). Patients developing osteitis around the FSOT have a higher risk of frontal sinus revision surgery. As mucosal damage can lead to osteitis, FSOT mucosa should be preserved during initial NP surgery. However, as multiple procedures are common among NP patients requiring frontal sinus revision, frontal sinus ostium enlargement should be considered during first revision in the hope of reducing the need of further revisions.

Abstract: International audience; Biochemical experiments, animal models, and observational studies in humans all support a role of dipeptidyl peptidase 4 (DPP4) in the N-terminal truncation of CXCL10, which results in the generation of an antagonist form of the chemokine that limits T-cell and NK cell migration. Motivated by the ability to regulate lymphocyte trafficking in vivo, we conducted two prospective clinical trials to test the effects of DPP4 inhibition on CXCL10 processing in healthy donors and in chronic hepatitis C patients, a disease in which DPP4 levels are found to be elevated. Participants were treated daily with 100 mg sitagliptin, a clinically approved DPP4 inhibitor. Plasma samples were analyzed using an ultrasensitive single-molecule assay (Simoa) to distinguish the full-length CXCL101-77 from the NH2-truncated CXCL103-77, as compared to the total CXCL10 levels. Sitagliptin treatment resulted in a significant decrease in CXCL103-77 concentration, a reciprocal increase in CXCL101-77, with only minimal effects on total levels of the chemokine. These data provide the first direct evidence that in vivo DPP4 inhibition in humans can preserve the bioactive form of CXCL10, offering new therapeutic opportunities for DPP4 inhibitors.

Abstract: SummaryBackground There is a relationship between liver stiffness measurement (LSM) and outcome of HCV patients. Aim To evaluate the performance of LSM to predict outcome of HCV patients at risk of liver-related complication. Methods We established a retrospective longitudinal cohort of 341 HCV patients with unequivocal cirrhosis. All underwent LSM and were followed from September 2006 to July 2015. Outcome measure was a composite end-point of end-stage liver disease (ESLD) and/or hepatocellular carcinoma (HCC). Cox models and areas under receiver operating characteristic (AUROC) curves were used to evaluate independent risk factors of outcome. Results Overall, LSM was below the 12.5 kPa threshold in 129 (37.8%) patients, including three-fourth and one-third of patients with or without a sustained virological response respectively. Liver disease progressed in 136 (39.9%) patients after a median observational period of 23.5 months. Older age, male gender, alcohol use disorders, metabolic syndrome and LSM were independent risk factors of liver disease progression. Age, alcohol use disorders and LSM were independently associated with ESLD. Age, gender and metabolic syndrome, but not LSM, were associated with HCC. The AUROC curves for disease progression, ESLD and HCC were 0.67, 0.70 and 0.58 respectively. Patients with a liver stiffness >12.5 kPa were at the highest risk of liver disease progression; below 12.5 kPa, liver stiffness was not discriminant. Conclusion Liver stiffness measurement is not a surrogate of disease progression of HCV patients with cirrhosis. HCV patients with cirrhosis should undergo the recommended follow-up, regardless of liver stiffness measurement.

Abstract: We read with interest the study by Welzel et al 1 confirming the high efficacy of oral direct-acting antiviral agents (DAAs) for the treatment of chronic HCV infection.2 Results about safety are less clear, since in these patients who have a high risk of hepatic decompensation or death within 12 months, the rate of death was 7.8% during treatment and the 12 weeks post-treatment. These deaths and most safety events were associated with advanced liver disease and not considered treatment related. The largest phase III studies (COSMOS, ION1 and ION3, SAPPHIRE) did not report any death during DAA treatment and severe adverse events occurring during therapy were considered to be unlikely related to DAAs.3 In real-life clinical settings, mortality has been observed in around 0.5% (0.3% for the French ANRS CO22 HEPATHER cohort and 0.6% for the US TARGET cohort).

Abstract: Chronic infection perturbs immune homeostasis. While prior studies have reported dysregulation of effector and memory cells, little is known about the effects on naïve T cell populations. We performed a cross-sectional study of chronic hepatitis C (cHCV) patients using tetramer-associated magnetic enrichment to study antigen-specific inexperienced CD8+ T cells (i.e., tumor or unrelated virus-specific populations in tumor-free and sero-negative individuals). cHCV showed normal precursor frequencies, but increased proportions of memory-phenotype inexperienced cells, as compared to healthy donors or cured HCV patients. These observations could be explained by low surface expression of CD5, a negative regulator of TCR signaling. Accordingly, we demonstrated TCR hyperactivation and generation of potent CD8+ T cell responses from the altered T cell repertoire of cHCV patients. In sum, we provide the first evidence that naïve CD8+ T cells are dysregulated during cHCV infection, and establish a new mechanism of immune perturbation secondary to chronic infection. DOI: http://dx.doi.org/10.7554/eLife.07916.001, eLife digest Long-lasting or “chronic” infections massively perturb the immune system as a way to favor their own growth. In particular, they can stop T cells – a subtype of immune cells that help to destroy viruses – from working well. For example, HIV and hepatitis C viruses can overwork T cells and cause them to die. This can make individuals vulnerable to other infections. In healthy people, T cells that have participated in the fight against particular infections continue to live to provide a memory of those past infections. Groups of “naïve” T cells that have not yet encountered an infected cell also patrol the body, ready to respond to infections by a new virus. There are relatively few virus-specific naïve T cells in the body, so until recently it has been hard to study them. As a result, researchers know little about how these cells are affected by long-lasting infections, and whether chronic infection affects our capacity to fight unrelated infections. Alanio et al. have now used a highly sensitive technique to compare naïve T cells found in the blood of three groups of people: those with chronic hepatitis C infections, those who have been cured of a chronic hepatitis C infection, and healthy people. This revealed that the naïve T cells are negatively affected by chronic hepatitis C infections, and become hypersensitive: they get easily overexcited, which can lead to their death. This compromises the immune defenses at the moment they are most needed. Closer inspection showed that the naïve T cells of patients with hepatitis C are hypersensitive because they have less of a protein called CD5 on their surface. This protein acts as a natural brake for the T cells, and thus having less results in the T cells mounting stronger immune responses. Although this might be beneficial when fighting certain infections, this may also account for conditions where T cells attack healthy tissues. Finally, Alanio et al. found evidence that people who have been cured of a chronic hepatitis C infection recover a healthy set of naïve T cells within two years. Treating patients as soon as an infection is diagnosed therefore has several benefits: as well as clearing the virus, this will reset the immune system balance and reduce the damage that hyperactive immune cells cause to the body. The results also have implications for vaccinations, which work by pushing naïve T cells to arm themselves against a particular virus. The discovery that naïve T cells are hypersensitive in patients with hepatitis C suggests that we may need a distinct strategy for efficiently vaccinating these patients. It is indeed possible that standard vaccines – tested in groups of healthy people – may result in unexpected and unwanted immune responses in individuals with hepatitis C. These open questions will be addressed in further studies. It will also be of interest to know if other chronic viruses have the same ability to alter the activity of naïve T cells.

Abstract: International audience; Chronic infection with HCV is a public health problem with approximately 170 million people infected worldwide. Interferon alpha (IFNα) sensitivity in liver and IL28B genotype has been identified as important determinants of HCV clearance in the setting of pegylated interferon/ribavirin treatment. Herein, we explored IFNα sensitivity in PBMC from 21 healthy donors and 21 HCV-infected patients treated with pegylated interferon/ribavirin and HCV nonstructural protein-3 inhibitors (i.e. telaprevir/boceprevir). We explored phospho-STAT1 level as read-out for IFN signalling pathway activation in PBMC, T cells and monocytes and correlated results with virological response. We found that PBMC from healthy donors are desensitized to IFNα after priming and challenged with IFNα, with a subsequent decrease of phospho-STAT1 and interferon-stimulated genes. Furthermore, we show that CD3+ T cells, but not monocytes, become desensitized after 4 weeks of treatment, with a significant decrease of phospho-STAT1 after ex vivo IFNα stimulation. Finally, we identified baseline phospho-STAT1 level in CD3+ T cells as a potential biomarker of sustained virological response, regardless of the IL28B genotype. In the upcoming costly era of IFN-sparing regimen, baseline IFNα sensitivity could act as biomarker to define cost-effectiveness strategies of treatment by identifying patients who will or will not respond to IFN-based treatments.

Abstract: There is currently no accepted treatment of chronic hepatitis E virus (HEV) infection.To report 2 patients in whom ribavirin therapy seemed to alter the natural history of chronic HEV infection.Case reports.Hepatology unit of a tertiary care center in France.A kidney and pancreas transplant recipient and a patient with idiopathic CD4(+) T lymphocytopenia, both with biopsy-proven chronic HEV infection.Patients received oral ribavirin, 12 mg/kg of body weight daily for 12 weeks.Liver function tests, detection of HEV RNA (viremia and stool shedding) by reverse transcriptase polymerase chain reaction, and anti-HEV IgM and IgG antibodies.Both patients had normalized liver function test results after 2 weeks of treatment and cleared HEV after 4 weeks of treatment. Hepatitis E virus RNA remained undetectable in the serum and stools throughout follow-up (3 months and 2 months for the first and second patient, respectively). Side effects were considered mild.Given the relatively short follow-up, the achievement of HEV eradication could not be claimed.Ribavirin is a potentially effective treatment of HEV infection and should be evaluated in patients with chronic HEV infection.None.

Abstract: International audience; Despite universal health coverage in France, migrants face specific socioeconomic barriers that increase the likelihood of a suboptimal cascade of care for chronic hepatitis C virus (HCV) infection and impaired treatment effectiveness in this sub-population. We selected data collected from 2012 to 2018 from the ANRS CO22 HEPATHER prospective cohort study for chronic HCV participants with available data on treatment failure (defined as the presence of a detectable HCV-RNA load 12 weeks after their first DAA treatment ended). We performed multivariable Poisson regression models to test whether treatment failure rates differed significantly between HCV-infected migrants and non-migrants receiving DAA in France (cross-sectional analysis), while taking into account the former's world region of birth and other potential social vulnerability factors. Among the study population's 7,879 patients, 5,829 (74%) were non-migrants and 2,050 (26%) migrants. Median [interquartile range] age was 57 [51-65] years, 4433 (56%) were men and 369 (5%) of the entire study population had treatment failure. After multivariable adjustment, only migrants from Central Asia were at higher risk of treatment failure than non-migrants (aIRR = 2.83; 95% CI [1.72, 4.65]). Results from this large-scale study performed in France suggest a higher risk of DAA treatment failure in migrants from Central Asia than in non-migrants and confirm the overall low treatment failure rate in chronic HCV patients treated with DAA (whether migrants or not). Simplified models of care taking into account language and cultural barriers are needed to improve DAA effectiveness in migrants from Central Asia.

Abstract: International audience; Chronic hepatitis C virus (HCV) infection is a risk factor of insulin resistance, and HCV-infected patients are at a high risk of developing diabetes. In the general population, research has shown the potential benefit of cannabis use for the prevention of diabetes and related metabolic disorders. We aimed to test whether cannabis use is associated with a lower risk of diabetes in chronic HCV-infected patients. Chronic HCV-infected patients (n = 10 445) were selected from the French national, multicenter, observational ANRS CO22 Hepather cohort. Cross-sectional data collected at cohort enrollment were used to assess the association between patients’ clinical and behavioural characteristics and the risk of diabetes. Logistic regression model was performed with cannabis use as the main independent variable and a significance level set at 5%. A similar model stratified by the presence of advanced liver fibrosis (FIB-4 > 3.25) was also run. After multivariable adjustment, current (AOR [95%CI]: 0.49 [0.38-0.63]) and former (0.81 [0.67-0.98], P

Abstract: International audience; Background: Simple and inexpensive non-invasive fibrosis tests are highly needed but have been poorly studied in sub-Saharan Africa.Methods: Using liver histology as a gold standard, we developed a novel index using routine laboratory tests to predict significant fibrosis in patients with chronic HBV infection in The Gambia, West Africa. We prospectively assessed the diagnostic accuracy of the novel index, Fibroscan, aspartate transaminase-to-platelet ratio index (APRI), and Fib-4 in Gambian patients with CHB (training set) and also in French and Senegalese CHB cohorts (validation sets).Results: Of 135 consecutive treatment-naïve patients with CHB who had liver biopsy, 39% had significant fibrosis (Metavir fibrosis stage ≥F2) and 15% had cirrhosis (F4). In multivariable analysis, gamma-glutamyl transpeptidase (GGT) and platelet count were independent predictors of significant fibrosis. Consequently, GGT-to-platelet ratio (GPR) was developed. In The Gambia, the area under the receiver operating characteristic curve (AUROC) of the GPR was significantly higher than that of APRI and Fib-4 to predict ≥F2, ≥F3 and F4. In Senegal, the AUROC of GPR was significantly better than Fib-4 and APRI for ≥F2 (0.73, 95% CI 0.59 to 0.86) and better than Fib-4 and Fibroscan for ≥F3 (0.93, 0.87 to 0.99). In France, the AUROC of GPR to diagnose ≥F2 (0.72, 95% CI 0.59 to 0.85) and F4 (0.87, 0.76 to 0.98) was equivalent to that of APRI and Fib-4.Conclusions: The GPR is a more accurate routine laboratory marker than APRI and Fib-4 to stage liver fibrosis in patients with CHB in West Africa. The GPR represents a simple and inexpensive alternative to liver biopsy and Fibroscan in sub-Saharan Africa.
