Inherited chromosomally integrated (ici) human herpes virus 6 (HHV-6) is estimated to occur in 0.6–2.7% of people worldwide. HHV-6 comprises two distinct species: HHV-6A and HHV-6B. Both HHV-6A and HHV-6B integration have been reported. Several drugs are capable of activating iciHHV-6 in tissues, the consequences of which are poorly understood. We report herein a case of a woman with iciHHV-6A+ and iciHHV-6B+, who developed ulipristal acetate (a selective progesterone receptor modulator)-induced fulminant hepatic failure that required liver transplantation. We confirmed the presence of ~one copy per cell of both HHV-6A and HHV-6B DNA in her hair follicles using multiplex HHV-6A/B real-time PCR and demonstrated the Mendelian inheritance of both iciHHV-6A and iciHHV-6B in her family members over three generations. Because of the rarity of this presentation, we discuss herein the possible links between reactivated HHV-6 from iciHHV-6A and/or iciHHV-6B and adverse drug reactions, suggesting that iciHHV-6 could be screened before the introduction of any hepatotoxic drugs to exclude HHV-6 active disease or combined idiosyncratic drug-induced liver injury in these patients.

International audience; Background & aims: Noninvasive tests (NITs) of liver fibrosis have been suggested to be less accurate in type 2 diabetes mellitus (T2DM). We aimed to compare the accuracy of 6 NITs between patients with or without T2DM, explain any differences, and adapt diagnostic algorithms for clinical practice accordingly.Methods: We included 1051 patients with nonalcoholic fatty liver disease with liver biopsy, blood fibrosis tests (Nonalcoholic Fatty Liver Disease Fibrosis Score, FIB4, Fibrotest, FibroMeter), vibration-controlled transient elastography (VCTE), and the combinatory elasto-blood test FibroMeterVCTE. The study endpoint was advanced fibrosis on liver biopsy.Results: NIT areas under the receiver operating characteristic curve were significantly lower in patients with T2DM, mostly because of a decrease in specificity. For FIB4, this decrease in specificity was only related to the higher age of patients with T2DM enrolled. For Fibrotest, FibroMeter, and FibroMeterVCTE, the decrease in specificity was related to age but also to higher alpha2-macroglobulin level, which is known to increase in T2DM. Sensitivity was unaffected by T2DM, but it masked a doubled raw number of false negatives because of the 2-fold higher prevalence of advanced fibrosis in that setting. The sequential algorithm FIB4-vibration-controlled transient elastography had 90.3% accuracy in patients without T2DM vs 79.0% in those with (P < .001). Algorithms using first-line specialized tests maintained a low rate of false negatives and false positives in T2DM.Conclusions: The decrease in NIT accuracy observed in T2DM is partly biased by the different characteristics of the groups studied, but also linked to T2DM itself through modification of the levels of some NIT biomarkers. Specialized tests should be used first-line to diagnose advanced liver fibrosis in T2DM.

The European Association for the Study of the Liver (EASL) has recently proposed an algorithm for the diagnosis of advanced liver fibrosis. We aimed to evaluate the diagnostic accuracy of this algorithm in nonalcoholic fatty liver disease (NAFLD).One thousand fifty-one patients with NAFLD, liver biopsy, and four noninvasive tests (NITs; Fibrosis-4 [FIB4], vibration controlled transient elastography [VCTE], FibroMeter, Fibrotest) were included. The enhanced liver fibrosis (ELF) score was available in 396 patients. A cohort of 230 patients from primary care/diabetes clinics had FIB4, VCTE, and ELF. Compared with the performance of single NITs, agreement between two NITs (FIB4 and VCTE, VCTE and patented serum tests) increased specificity and positive predictive value by 20%, thus justifying the sequential use proposed in the EASL algorithm. The FIB4/VCTE/FibroMeter and FIB4/VCTE/Fibrotest algorithms performed similarly, providing 85% diagnostic accuracy and a liver biopsy requirement rate of only 10%. The FIB4/VCTE/ELF algorithm performed similarly in the subgroup where ELF was available. Simulations of algorithm accuracies at different prevalence showed that positive predictive values rapidly increased, reaching a plateau above 75% starting at 15% prevalence. Negative predictive values remained higher than 90% up to 25% prevalence. The rate of liver biopsy requirement remained stable, increasing by only 5% between low and high prevalence settings. When the EASL algorithm was applied in the primary care/diabetes clinic cohort, liver biopsy requirement was only 3%, and the agreement among the three steps provided 75% positive predictive value.Our study validates the algorithm proposed by the EASL in its latest 2021 guidelines for the diagnosis of advanced fibrosis in the setting of NAFLD.

[Background & Aims] Previous studies on the prognostic significance of non-invasive liver fibrosis tests in non-alcoholic fatty liver disease (NAFLD) lack direct comparison to liver biopsy. We aimed to evaluate the prognostic accuracy of fibrosis-4 (FIB4) and vibration-controlled transient elastography (VCTE), compared to liver biopsy, for the prediction of liver-related events (LREs) in NAFLD., [Methods] A total of 1,057 patients with NAFLD and baseline FIB4 and VCTE were included in a multicenter cohort. Of these patients, 594 also had a baseline liver biopsy. The main study outcome during follow-up was occurrence of LREs, a composite endpoint combining cirrhosis complications and/or hepatocellular carcinoma. Discriminative ability was evaluated using Harrell’s C-index., [Results] FIB4 and VCTE showed good accuracy for the prediction of LREs, with Harrell’s C-indexes >0.80 (0.817 [0.768-0.866] vs. 0.878 [0.835-0.921], respectively, p = 0.059). In the biopsy subgroup, Harrell’s C-indexes of histological fibrosis staging and VCTE were not significantly different (0.932 [0.910-0.955] vs. 0.881 [0.832-0.931], respectively, p = 0.164), while both significantly outperformed FIB4 for the prediction of LREs. FIB4 and VCTE were independent predictors of LREs in the whole study cohort. The stepwise FIB4-VCTE algorithm accurately stratified the risk of LREs: compared to patients with “FIB4 12.0 kPa” (aHR 12.4; 95% CI 5.1–30.2)., [Conclusion] VCTE and FIB4 accurately stratify patients with NAFLD based on their risk of LREs. These non-invasive tests are alternatives to liver biopsy for the identification of patients in need of specialized management., Intercept Pharmaceuticals provided grant support.

Hepatic small vessel neoplasm is a new entity with a characteristic appearance in imaging and must be recognized and differentiated from hemangioma to allow appropriate management.

International audience; Background & aims: Two-dimensional shear wave elastography (2D-SWE) is an accurate method for the non-invasive evaluation of liver fibrosis. We aimed to determine the reliability criteria and the number of necessary reliable measurements for 2D-SWE.Methods: 788 patients with chronic liver disease underwent liver biopsy and 2D-SWE examination in three centers. The 4277 2D-SWE measurements performed were 2:1 randomly divided into derivation (n = 2851) and validation (n = 1426) sets. Reliability criteria for a 2D-SWE measurement were defined in the derivation set from the intrinsic characteristics given by the device (mean liver stiffness, standard deviation, diameter of the region of interest), with further evaluation in the validation set.Results: In the whole population of 4277 measurements, AUROC for bridging fibrosis was 0.825 ± 0.006 and AUROC for cirrhosis was 0.880 ± 0.006. Mean stiffness and coefficient of variation (CV) were independent predictors of bridging fibrosis or cirrhosis. From these two parameters, new criteria were derived to define a reliable 2D-SWE measurement: stiffness

Although coronary artery disease (CAD) and advanced liver fibrosis (AdLF) are commonly associated in patients with non-alcoholic fatty liver disease (NAFLD), the prevalence of AdLF and the diagnostic performance of non-invasive fibrosis tests (NITs) in CAD patients remains unknown. We aimed to prospectively screen for AdLF in patients with documented CAD using NITs and Fibroscan. High and intermediate zones of NITs were combined to define AdLF. AdLF was suspected whenever APRI ≥ 0.5, Forns index ≥ 4.2, NAFLD fibrosis score (NFS) ≥ -1.455/0.12 for age 2), AdLF ranged between 10% (APRI) to 84% (Forns). In this subgroup, the most efficient NITs to predict Fibroscan ≥ 8 kPa were eLIFT (Se 60%, Sp 70%) and NFS (Se 70%, Sp 60%). Finally, in CAD patients with risk factors for NAFLD, NFS or the more user-friendly eLIFT are the most attractive first-line biochemical NITs to discriminate good candidates for Fibroscan.

Introduction: Accumulating evidence supports a bidirectional association between nonalcoholic steatohepatitis (NASH) and type 2 diabetes (T2D). There is a clinical challenge to consider pharmaceuti...

Because of the high prevalence of chronic liver disease (CLD), it is crucial that general practitioners (GPs, in contact with the general population) and diabetologists (in contact with the most at-risk non-alcoholic fatty liver disease population) identify patients with advanced CLD requiring specialized management. The aim of this study was to evaluate CLD and CLD management awareness among diabetologists and GPs.A questionnaire was sent to diabetologists within the Francophone Diabetes Society and to GPs in southern and western France. The questionnaire sounded participant characteristics and knowledge of CLD and its management.678 questionnaires were completed by 500 GPs and 178 diabetologists. CLD prevalence was underestimated by 90% of GPs and 59% of diabetologists (p0.001). For biological CLD follow-up, liver injury explorations (transaminases) were systematically included whereas severity explorations (prothrombin time, bilirubin) were prescribed for less than 50% of blood samples; GPs were more likely to prescribe severity explorations than diabetologists were (p0.001). 74% of GPs and 97% of diabetologists (p0.001) were familiar with non-invasive tests, Fibroscan and Fibrotest being the two most-frequently mentioned of them. In contrast, the simple blood test Fibrosis-4 was cited by less than 15% of GPs and 30% of diabetologists (p0.001).GPs and diabetologists have limited knowledge of CLD, despite its high prevalence. Continuing medical education among GPs and diabetologists is therefore necessary to enable the discovery of patients with advanced fibrosis and early management for them so as to avoid liver-related complications.

BACKGROUND AND AIMS The combination of laboratory and elastography tests allows the accurate diagnosis of advanced liver fibrosis in patients with NAFLD. In this study, we compared the diagnostic performances of a two-step strategy (laboratory tests and vibration-controlled transient elastography [VCTE] or two-dimensional shear-wave elastography with SuperSonic Imagine [2D-SWE-SSI]) and the added value of a three-step strategy (laboratory tests and two elastography methods). APPROACH AND RESULTS From a prospective registry, we retrospectively selected 577 consecutive patients with suspicion of NAFLD who underwent laboratory tests to calculate the Fibrosis-4 (FIB-4) score, liver stiffness evaluation by VCTE (M and XL probes) and 2D-SWE-SSI, and liver biopsy. The diagnostic performances and need for liver biopsy in unclassified patients for the diagnosis of advanced fibrosis (F ≥ 3) in multistep strategies were compared. The area under the curve of FIB-4, VCTE, and 2D-SWE-SSI was 0.74, 0.82, and 0.88, respectively. Using the same thresholds, the FIB-4/2D-SWE-SSI and FIB-4/VCTE diagnostic performances were comparable (sensitivity, 71.4% and 66%; specificity, 91.4% and 91.5%; and accuracy, 83.7% and 81.4%; all P = not significant). Conversely, more patients required liver biopsy after 2D-SWE-SSI (24.6% versus 15.3%, P

Background and Aim The main aim of this study was to evaluate if the binge eating disorders (BEDs) related to obesity were associated with the severity of non‐alcoholic fatty liver disease (NAFLD). Methods Severely obese patients who had been referred for bariatric surgery were included in this study at the Nice University Hospital. All patients underwent a liver biopsy at the time of surgery. Between 2008 and 2015, 388 patients had an assessable Bulimia Test (BULIT) self‐questionnaire at the time of surgery. A subgroup (n = 183), between 2011 and 2015, also responded to a Beck Depression Inventory, Hospital Anxiety and Depression Scale, and a Fatigue Impact Scale autoquestionnaire. A control group of 29 healthy people matched by age and gender was included. Results Among the 388 obese patients (median age 40 years, body mass index 41.7 kg/m2, 81% women), 14 patients had a “probable diagnosis” of BED, and 47 patients had a “high risk” of developing a BED according to the BULIT. Obese patients had significantly more severe BED, depression, anxiety, and fatigue compared to controls. Steatosis, non‐alcoholic steatohepatitis, or fibrosis was not associated with BED. Similarly, the severity of NAFLD was not associated with depression, anxiety, or fatigue. Conclusions Severely obese patients had more severe BED, depression, anxiety, and fatigue than lean subjects independent of the severity of NAFLD., Non‐alcoholic fatty liver disease, the emerging liver disease of the 21st century, is related to obesity. However, binge eating disorders, and also frequently associated psychiatric disorders (depression, anxiety, and fatigue), are not associated with the severity of liver pathology in severely obese patients.

The proteolytic cleavage of Fibronectin type III domain-containing 5 (FNDC5) generates soluble irisin. Initially described as being mainly produced in muscle during physical exercise, irisin mediates adipose tissue thermogenesis and also regulates carbohydrate and lipid metabolism. The aim of this study was to evaluate the hepatic expression of FNDC5 and its role in hepatocytes in Non-Alcoholic Fatty Liver (NAFL). Here we report that hepatic expression of FNDC5 increased with hepatic steatosis and liver injury without impacting the systemic level of irisin in mouse models of NAFLD (HFD and MCDD) and in obese patients. The increased Fndc5 expression in fatty liver resulted from its upregulation in hepatocytes and non-parenchymal cells in mice. The local production of Fndc5 in hepatocytes was influenced by genotoxic stress and p53-dependent pathways. The down-regulation of FNDC5 in human HepG2 cells and in primary mouse hepatocytes increased the expression of PEPCK, a key enzyme involved in gluconeogenesis associated with a decrease in the expression of master genes involved in the VLDL synthesis (CIDEB and APOB). These alterations in FNDC5-silenced cells resulted to increased steatosis and insulin resistance in response to oleic acid and N-acetyl glucosamine, respectively. The downregulation of Fndc5 also sensitized primary hepatocytes to apoptosis in response to TNFα, which has been associated with decreased hepatoprotective autophagic flux. In conclusion, our human and experimental data strongly suggest that the hepatic expression of FNDC5 increased with hepatic steatosis and its upregulation in hepatocytes could dampen the development of NAFLD by negatively regulating steatogenesis and hepatocyte death.

Background Increased adipokine production and hyperfiltration may explain the links between obesity and chronic kidney disease. Indeed, hyperfiltration may precede a subsequent accelerated decline of kidney function in these patients. Glomerular filtration rate decreases after bariatric surgery in young obese patients with hyperfiltration. Objective Our aim was to identify the factors associated with this decrease 1 year after bariatric surgery. Setting We used data from a prospective cohort of severely obese patients who underwent bariatric surgery in Nice University Hospital. Methods We analyzed 175 patients before and 1 year after bariatric surgery. Low-grade inflammation was evaluated by serum C-reactive protein levels. Lean body mass and fat body mass were estimated by bioelectric impedance analysis. Body surface area was assessed by the Du Bois formula. Serum creatinine levels were used to estimate glomerular filtration rate by the chronic kidney disease-epidemiology collaboration (CKD-EPI) equation. Glomerular filtration rate was de-adjusted from standard body surface area and then divided by lean body mass to calculate the decrease in hyperfiltration and to separate the patients into 2 groups: above or below the median decrease of hyperfiltration after bariatric surgery. Results The factors associated with a large correction of hyperfiltration were baseline C-reactive protein levels (10.0 ± 5.8 mg/L versus 12.7 ± 7.4 mg/L, P = .01) and brachial circumference (41 ± 4 cm versus 44 ± 5 cm, P = .006). A high fat mass reduction rate was significantly associated with a substantial hyperfiltration reduction after bariatric surgery ( P Conclusions The correction of hyperfiltration is associated with a high reduction rate of fat mass after bariatric surgery but may be limited by low-grade inflammation.

Background & Aims Cluster of differentiation (CD)44 regulates adipose tissue inflammation in obesity and hepatic leukocyte recruitment in a lithogenic context. However, its role in hepatic inflammation in a mouse model of steatohepatitis and its relevance in humans have not yet been investigated. We aimed to evaluated the contribution of CD44 to non-alcoholic steatohepatitis (NASH) development and liver injury in mouse models and in patients at various stages of non-alcoholic fatty liver disease (NAFLD) progression. Methods The role of CD44 was evaluated in CD44 −/− mice and after injections of an αCD44 antibody in wild-type mice challenged with a methionine- and choline-deficient diet (MCDD). In obese patients, hepatic CD44 (n=30 and 5 NASH patients with a second liver biopsy after bariatric surgery) and serum sCD44 (n=64) were evaluated. Results Liver inflammation (including inflammatory foci number, macrophage and neutrophil infiltration and CCL2/CCR2 levels), liver injury and fibrosis strongly decreased in CD44 −/− mice compared to wild-type mice on MCDD. CD44 deficiency enhanced the M2 polarization and strongly decreased the activation of macrophages by lipopolysaccharide (LPS), hepatocyte damage-associated molecular patterns (DAMPs) and saturated fatty acids. Neutralization of CD44 in mice with steatohepatitis strongly decreased the macrophage infiltration and chemokine ligand (CCL)2 expression with a partial correction of liver inflammation and injury. In obese patients, hepatic CD44 was strongly upregulated in NASH patients ( p =0.0008) and correlated with NAFLD activity score (NAS) ( p =0.001), ballooning ( p =0.003), alanine transaminase ( p =0.005) and hepatic CCL2 ( p p + cells. Finally, the soluble form of CD44 increased with severe steatosis ( p =0.0005) and NASH ( p =0.007). Conclusion Human and experimental data suggest that CD44 is a marker and key player of hepatic inflammation and its targeting partially corrects NASH. Lay summary Human and experimental data suggest that CD44, a cellular protein mainly expressed in immune cells, is a marker and key player of non-alcoholic steatohepatitis (NASH). Indeed, CD44 enhances the non-alcoholic fatty liver (NAFL) (hepatic steatosis) to NASH progression by regulating hepatic macrophage polarization (pro-inflammatory phenotype) and infiltration (macrophage motility and the MCP1/CCL2/CCR2 system). Targeting CD44 partially corrects NASH, making it a potential therapeutic strategy.

A deficiency in vitamin D could be deleterious during chronic liver diseases. However, contradictory data have been published in patients with non-alcoholic fatty liver disease. The aim of the study was to compare the blood level of 25 hydroxy vitamin D (25-OH vitamin D) with the severity of liver lesions, in a large cohort of morbidly obese patients. Three hundred ninety-eight morbidly obese patients had a liver biopsy. The non-alcoholic steatohepatitis (NASH) Clinical Research Network Scoring System Definition and Scores were used. 25-OH vitamin D was evaluated with a Diasorin®Elisa Kit. Logistic regression analyses were performed to obtain predictive factors of the severity of liver histology. 20.6 % of patients had NASH. The stage of fibrosis was F0 12.9 %, F1 57.36 %, F2 25.32 %, F3 (bridging fibrosis) 3.88 %, and F4 (cirrhosis) 0.52 %. The 25-OH vitamin D level inversely correlated to the NAS (r = 0.12 and p = 0.01) and to steatosis (r = 0.14 and p = 0.007); however, it was not associated with the presence of NASH. The level of vitamin D was significantly lower in patients with significant fibrosis compared to those without (15.9 (11.1–23.5) vs 19.6 (13.7–24.7) ng/ml, p = 0.02). There was an inverse correlation between the severity of fibrosis and the values of 25-OH vitamin D (r = 0.12 and p = 0.01). In a logistic regression analysis, no parameters were independently associated with the severity of fibrosis except the presence of steatohepatitis (1.94 (1.13–3.35) p = 0.017). Low levels of 25-OH vitamin D were not independently associated with liver damage in morbidly obese patients with non-alcoholic fatty liver diseases (NAFLD).

Improved understanding of the molecular mechanisms responsible for the progression from a “non-pathogenic” steatotic state to Non-Alcoholic Steatohepatitis is an important clinical requirement. The cell death-inducing DFF45 like effector (CIDE) family members (A, B and FSP27) regulate hepatic lipid homeostasis by controlling lipid droplet growth and/or VLDL production. However, CIDE proteins, particularly FSP27, have a dual role in that they also regulate cell death. We here report that the hepatic expression of CIDEA and FSP27 (α/β) was similarly upregulated in a dietary mouse model of obesity-mediated hepatic steatosis. In contrast, CIDEA expression decreased, but FSP27-β expression strongly increased in a dietary mouse model of steatohepatitis. The inverse expression pattern of CIDEA and FSP27β was amplified with the increasing severity of the liver inflammation and injury. In obese patients, the hepatic CIDEC2 (human homologue of mouse FSP27β) expression strongly correlated with the NAFLD activity score and liver injury. The hepatic expression of CIDEA tended to increase with obesity, but decreased with NAFLD severity. In hepatic cell lines, the downregulation of FSP27β resulted in the fractionation of lipid droplets, whereas its overexpression decreased the expression of the anti-apoptotic BCL2 marker. This, in turn, sensitized cells to apoptosis in response to TNF α and saturated fatty acid. Considered together, our animal, human and in vitro studies indicate that differential expression of FSP27β/CIDEC2 and CIDEA is related to NAFLD progression and liver injury.

International audience; Background In liver transplant recipients with hepatitis C virus recurrence, there is concern about renal safety of sofosbuvir-based regimens. Changes in serum creatinine or in the estimated glomerular filtration rate (eGFR) under treatment are used to look for possible renal toxicity. However, serum creatinine and eGFR are highly variable. Aim To analyse renal function trajectory with numerous assays of serum creatinine over a long period of time. Methods In a multicentre cohort of 139 patients, the eGFR was obtained from serum creatinine using the Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) equation. Slopes of eGFR were defined as a change in eGFR during a period divided by time. Pre-treatment, on-treatment and post-treatment periods were 9 months, 3-9 months and 4.5 months. Interactions between eGFR slopes and the pre-treatment eGFR, use of ribavirin or mycophenolate mofetil, and stage of fibrosis were addressed. On-treatment eGFR slopes were separated in tertiles. Pre- and post-treatment eGFR slopes were compared globally and according to tertiles. Results The post-treatment eGFR slope was significantly better than pre-treatment eGFR slope (+0.18 (IQR -0.76 to +1.32) vs -0.11 (IQR -1.01 to +0.73) mL/min/1.73 m(2)/month, P=0.03) independently of the pre-treatment eGFR (P=0.99), ribavirin administration (P=0.26), mycophenolate mofetil administration (P=0.51) and stage of fibrosis (F3 and F4 vs lower stages, P=0.18; F4 vs lower stages, P=0.08; F4 Child-Pugh B and C vs lower stages, P=0.38). Tertiles of on-treatment eGFR slopes were -1.71 (IQR -2.54 to -1.48), -0.78 (IQR -1.03 to -0.36) and +0.75 (IQR +0.28 to +1.47) mL/min/1.73 m(2)/month. Pre- and post-treatment eGFR slopes were not significantly different according to tertiles (respectively, P=0.34, 0.08, 0.73). Conclusion The eGFR varies during treatment and gives a confusing picture of the renal safety of sofosbuvir-based regimens. In contrast, longitudinal assessment of the eGFR shows a rising trajectory over longer time, meaning that these therapies are safe for the kidneys in our cohort of liver transplant recipients.

International audience; OBJECTIVES: We aimed to assess the performance of a new strip (Periscreen) for the rapid diagnosis of spontaneous bacterial peritonitis (SBP). METHODS: Ascitic fluid (AF) of cirrhotic patients hospitalized between March 2014 and August 2015 was independently tested by two readers using the new strip, which has four colorimetric graduations (negative, trace, small, and large). SBP was diagnosed on neutrophils in ascites>250/mm(3). Ascites not related to portal hypertension were excluded. RESULTS: Overall, 649 patients from 21 French centers were included and 1,402 AF (803 AF samples from 315 outpatients and 599 samples from 334 inpatients) were assessed. Eighty-four AF samples (17 AF in 9 outpatients and 67 AF in 31 inpatients) were diagnosed as SBP. The prevalence of SBP was 6% (2.1% in outpatients vs. 11.2% in inpatients; P

Background Immunoglobulin G4-related disease is a multi-systemic autoimmune disease. The sole involvement of the liver has been recently reported in Japanese patients and named “immunoglobulin G4-associated autoimmune hepatitis”. Aim To examine the baseline and the 2-year follow-up characteristics of non-Asian patients with immunoglobulin G4-associated autoimmune hepatitis compared to patients with classical autoimmune hepatitis. Methods This was a retrospective study of patients who had undergone liver biopsy between March 2009 and January 2012 before starting any treatment. All patients were treated according to the guidelines. Immunoglobulin G4-associated autoimmune hepatitis was diagnosed according to Umemura's histological definition: at least 10 positive immunoglobulin G4-plasma cells per high power field. Results Among 28 enrolled patients (males 39%, median age 54 years): 7 had immunoglobulin G4-associated autoimmune hepatitis (25%) and 21 had classical hepatitis; fibrosis and activity stages were F1: 57%, F2: 11%, F3: 11%, F4: 21% and A1: 18%, A2: 39%, A3: 43%. Alanine aminotransferase (ALT) activity and serum immunoglobulin G levels were similar in the two groups at baseline and at 2 years. Complete biochemical response (normal ALT) was similar in immunoglobulin G4-associated autoimmune hepatitis and classical hepatitis (67% vs. 59% at 2 years, p = 0.74). Conclusion Immunoglobulin G4-associated autoimmune hepatitis has been observed in Western patients and seems to evolve in a similar manner to classical hepatitis.

Background Among its pleiotropic effects, vitamin D may protect the liver from fibrosis and/or inflammation. However, the impact of vitamin D on liver pathology in hepatitis C remains unclear, and very few studies including alcoholic patients with liver pathologies have been performed. Here we compared the levels of 25-OH vitamin D in the blood of alcoholic patients with the occurrence of alcoholic steatohepatitis (ASH) or bridging fibrosis. Methods One hundred and one alcoholic patients were included. All the patients received a liver biopsy, and the levels of 25-OH vitamin D were evaluated with the Liaison 25-OH vitamin D assay. Logistic regression analyses were performed to obtain predictive factors of liver histology. Results Among alcoholic patients, 40.6% presented ASH and 39.6% presented bridging fibrosis. A severe deficiency in 25-OH vitamin D (
