Liver test abnormalities are frequent in adult patients with Turner syndrome, corresponding to various pathophysiological mechanisms. Steatosis, steatofibrosis and steatohepatitis are the most frequently reported lesions, caused by metabolic disorders, which are commonly related to overweight. Marked architectural changes, including nodular regenerative hyperplasia, multiple focal nodular hyperplasia and cirrhosis, found in some patients, are associated with a risk of severe liver-related complications. Architectural changes are often observed and are associated with vascular disorders caused by congenitally abnormal vessels. Finally, small bile duct alterations resembling sclerosing cholangitis occur in several patients. Oestrogen replacement therapy does not cause liver toxicity in patients with Turner syndrome and is not contraindicated in case of elevated liver enzymes. Moreover, in recent studies, oestrogen therapy was reported to improve liver function tests. Because of the wide spectrum of potential liver injuries that may occur in Turner syndrome patients, a regular screening of liver enzymes is recommended for early detection and treatment. © 2012 John Wiley & Sons A/S.

Background & Aims: Compared to HCV-mono-infected patients, hepatocellular carcinoma (HCC) occurs at younger age in HIV/HCV-co-infected patients, is markedly more advanced at diagnosis, is less amenable to curative treatment, and has a more severe outcome. The aim of this study was to identify factors predictive of HCC occurrence in a large cohort of HIV/HCV-co-infected patients with cirrhosis. Methods: This study involved 244 HIV/HCV-co-infected patients included in the ANRS CO13 HEPAVIH cohort, who had HCV-related cirrhosis (clinically or histologically proven cirrhosis, or liver stiffness ≥12.5 kPa) and no signs of HCC at baseline. Cox proportional hazards models were used to identify factors associated with HCC occurrence. Results: During a median follow-up of 2.6 (IQR, 1.8-3.5) years, 21 patients (8.6%) developed HCC. Diagnosis of HCC was based on histology in 5 patients (24%) and non-invasive criteria in 16 patients (76%). In univariate analyses, the following factors were related to HCC occurrence: age, previous cirrhosis decompensation, a HOMA value >3.8 (patients with treated diabetes were excluded from the HOMA calculation), a lower platelet count, a lower prothrombin level, and higher alpha-fetoprotein levels. The HOMA value was >3.8 at baseline in 66.7% of patients who developed HCC and in 35.3% of the remaining patients (p = 0.016). In multivariate analysis, age over 50 years (adjusted RR 3.2, 95% CI 1.2-9.0; p = 0.02) and a HOMA value >3.8 (adjusted RR 3.4, 95% CI 1.1-10.3; p = 0.03) remained significantly associated with HCC occurrence. Conclusions: As in HCV-mono-infected patients with HCV-related cirrhosis, insulin resistance appears to play a key role in HCC occurrence in HCV/HIV-co-infected patients with cirrhosis. This finding calls for specific screening strategies for patients with a particularly high risk of developing HCC. © 2011 European Association for the Study of the Liver. Published by Elsevier B.V.

Objectives: :. To develop fact sheets about tocilizumab, in order to assist physicians in the management of patients with inflammatory joint disease. Methods: :1.selection by a committee of rheumatology experts of the main topics of interest for which fact sheets were desirable;2.identification and review of publications relevant to each topic;3.development of fact sheets based on three levels of evidence: evidencebased medicine, official recommendations, and expert opinion. The 20 experts were rheumatologists and invited specialists in other fields, and they had extensive experience with the management of RA. They were members of the CRI (Club Rhumatismes et Inflammation), a section of the Société Francaise de Rhumatologie. Each fact sheet was revised by several experts and the overall process was coordinated by three experts. Results: :. Several topics of major interest were selected: contraindications of tocilizumab; the management of adverse effects and concomitant diseases that may develop during tocilizumab therapy; and the management of everyday situations such as pregnancy, surgery, and immunizations. After a review of the literature and discussions among experts, a consensus was developed about the content of the fact sheets presented here. These fact sheets focus on several points:1.in RA, initiation and monitoring of tocilizumab therapy, management of patients with specific past histories, and specific clinical situations such as pregnancy;2.diseases other than RA, such as juvenile idiopathic arthritis;3.models of letters for informing the rheumatologist and general practitioner;4.and patient information. Conclusion: :. These tocilizumab fact sheets built on evidence-based medicine and expert opinion will serve as a practical tool for assisting physicians who manage patients on tocilizumab therapy. They will be available continuously at www.cri-net.com and updated at appropriate intervals. © 2010 Elsevier Masson SAS. All rights reserved. Source

Context: Paucisymptomatic forms of Turner's syndrome (TS), in which short stature is the predominant clinical abnormality, remain underdiagnosed. Abnormal liver tests are extremely frequent in adult TS patients reflecting various types of hepatic lesions. Objective: The objective of the study was to investigate whether unexplained elevated liver enzymes in women with short stature could reveal X chromosome abnormalities of undiagnosed TS. Design and Participants: Thirty-one consecutive short stature women displaying elevated liver enzymes and no previous diagnosis of TS were compared with 31 age-matched controls in a prospective study. Liver biopsy was performed in 26 patients. Main Outcome Measures: Systematic karyotype analysis and fluorescence in situ hybridization. Results: X chromosome abnormalities were found in 27 patients and one control (87.0% vs 3.2%, P < .0001), including a 45,X/46,XX mosaicism in 24 patients and isochromosome of the long arm in three. Liver histological analysis showed architectural changes in 17 patients with nodular regenerative hyperplasia in 12. Biliary lesions were present in 13 patients and liver steatosis in 20. Conclusions: X chromosome abnormalities indicative of cryptic TS are extremely frequent in shortstature women with unexplained elevated liver enzymes. In short-stature women, abnormal liver tests should lead to systematic karyotype analysis. Copyright © 2014 by the Endocrine Society. Source

Background and Aims: Hepatic stellate cells, the major producers of extracellular matrix in the liver, and hepatocytes bear CXCR4 and CCR5, the two main co-receptors for entry of the human immunodeficiency virus (HIV). In vitro studies suggest that HIV-envelope proteins can modulate the replication of hepatitis C virus (HCV) and fibrogenesis. We investigated the influence of HIV tropism on liver fibrosis and the concentration of HCV RNA in HIV-HCV co-infected patients. Methods: We used a phenotypic assay to assess HIV tropism in 172 HCV-HIV co-infected patients: one group (75 patients) had mild fibrosis (score ≤F2) and the other (97 patients) had severe fibrosis (score >F2). We also assessed the relationship between HIV tropism and HCV RNA concentration in all these patients. We also followed 34 of these patients for 3 years to determine the evolution of HIV tropism and liver fibrosis, estimated by liver stiffness. Results: Initially, most patients (91.8%) received a potent antiretroviral therapy. CXCR4-using viruses were found in 29% of patients. The only factor associated with a CXCR4-using virus infection in multivariate analysis was the nadir of CD4 cells: <200/mm3 (OR: 3.94, 95%CI: 1.39-11.14). The median HCV RNA concentrations in patients infected with R5 viruses, those with dual-mixed viruses and those with X4 viruses, were all similar. The prevalence of CXCR4-using viruses in patients with mild fibrosis (≤F2) (31%) and those with severe fibrosis (F3-F4) (28%, p = 0.6) was similar. Longitudinal analyses showed that the presence of CXCR4-using viruses did not increase the likelihood of fibrosis progression, evaluated by measuring liver stiffness. Conclusions: The presence of CXCR4-using viruses in patients receiving a potent antiretroviral therapy does not influence HCV RNA concentration or liver fibrosis. © 2012 Abravanel et al. Source
