Abstract
BACKGROUND Concomitant Diabetes mellitus (DM) is commonly recognized in patients with chronic hepatitis B (CHB) infection, although its impact on liver-related outcomes remains controversial. We aimed to evaluate the effect of DM on the course, management and outcome of patients with CHB. METHODS We performed a large retrospective cohort study utilizing the Leumit-Health-Service (LHS) database. We reviewed electronic reports of 692106 LHS members from different ethnicities and districts in Israel from 2000-2019 and included patients with CHB diagnosis based on ICD-9-CM codes and supportive serology results. These were divided into two cohorts of patients with CHB and DM (CHD-DM) (N.=252) and those with CHB without DM (N.=964). Clinical parameters, treatment figures and patients' outcomes were compared and multiple regression models and Cox regression analysis were performed to investigate the association between DM and cirrhosis/HCC risk in CHB patients. RESULTS CHD-DM patients were significantly older (49.2±10.9 vs. 37.9±14, P<0.001), and had higher rates of obesity (BMI>30) and NAFLD (47.2% vs. 23.1%, and 27% vs. 12.6%, P<0.001, respectively). Both groups had a predominance of inactive carrier (HBeAg negative infection) state, but the HBeAg seroconversion rate was significantly lower in the CHB-DM group (25% vs. 45.7%; P<0.01). Multivariable Cox regression analysis showed that DM was independently associated with increased cirrhosis risk (HR 2.63; P=0.002). Older age, advanced fibrosis and DM were associated with HCC, but DM did not reach significance (HR 1.4; P=0.12) possibly due to the small number of HCC cases. CONCLUSIONS Concomitant DM in CHB patients was significantly and independently associated with cirrhosis and possibly with increased risk of HCC.

Abstract
Background Diabetes is one of the most common diseases and major public health burdens worldwide. Type 2 diabetes mellitus (T2DM) is associated with chronic hepatitis C virus (HCV) infection, and lncRNAs play an important role in HCV-induced T2DM. We aimed to explore the effect of lncRNA AC040162.3 on HCV-induced T2DM. Methods HCV was used to infect MIN6 cells to establish an in vitro model. HCV copy number and miRNA expression were detected by Real Time Quantitative PCR (RT-qPCR). Enzyme-Linked Immunosorbent Assay (ELISA) was used to detect the secretion of insulin, and methyl thiazolyl tetrazolium (MTT) was applied to analyze cell viability. Apoptosis was analyzed by Western blotting and flow cytometry. In addition, Western blotting and TdT-mediated dUTP Nick End Labeling (TUNEL) were used to analyze pyroptosis. Luciferase reporter assays were used to investigate the targeting relationship. Results The expression of LncRNA AC040162.3 and NLRP3 was markedly increased in HCV-T2DM, while the expression of miR-223-3p was remarkably inhibited. In vitro experiments demonstrated that lncRNA AC040162.3 silencing or miR-223-3p overexpression remarkably alleviated HCV-induced T2DM deterioration by inhibiting cell apoptosis and pyroptosis and enhancing cell viability. We then demonstrated that silencing lncRNA AC040162.3 promoted the expression of miR-223-3p and that miR-223-3p bound to lncRNA AC040162.3 and the NLRP3 binding site. In addition, the protective effects of LncRNA AC040162.3 silencing in HCV-infected MIN6 cells were reversed by overexpression of NLRP3 or silencing of miR-223-3p. Conclusion Silencing of lncRNA AC040162.3 alleviates the process of HCV-induced T2DM by governing the miR-223-3p/NLRP3 axis.

Abstract
BACKGROUND AND STUDY AIMS Little is known about the true prevalence of hepatitis B virus (HBV) coinfection in patients with hepatitis C virus (HCV). This multicenter nationwide study aimed to assess the seroprevalence of HBV among Egyptian patients with HCV and its possible risk factors. PATIENTS AND METHODS This is a cross-sectional, multicenter, nationwide study. Data were extracted from the National Network of Viral Hepatitis Treatment Centers database. Baseline data of patients proved to be viremic during the national campaign for HCV eradication (October 2018-April 2019) were retrieved. Data included demographics, laboratory tests (HBsAg, CBC, liver biochemical profile, creatinine, AFP, HbA1c, and viral load), FIB-4 score calculation, and abdominal ultrasound results. RESULTS Results of 297,965 patients showed that HBsAg was positive in 2,347 (0.8%) patients. Patients with HBV/HCV were 57% females and had a mean age of 51 ± 13 years. Patients with positive HBsAg showed significantly more tobacco consumption, intravenous drug abuse, hypertension, and diabetes. No significant difference was noted in HCV viremia between patients with HCV and those with HBV/HCV. Only 14% of patients with HBV/HCV had cirrhosis compared with the 9% of those with HCV; two of them had HCC. CONCLUSION Although Egypt has a heavy HCV burden, the overall prevalence of HBV is low among patients with HCV infection. Comorbid conditions seem to favor coinfection.

Abstract
Hepatocellular carcinoma (HCC) is one of the leading contributors to cancer mortality worldwide and is a leading cause of death in individuals with chronic hepatitis B virus (HBV) infection. It is uncertain how the presence of other metabolic factors and comorbidities influences HCC risk in HBV. Therefore, we performed a systematic literature review and meta-analysis to seek evidence for significant associations. MEDLINE, EMBASE and Web of Science databases were searched from 1 January 2000 to 24 June 2020 for studies investigating associations of metabolic factors and comorbidities with HCC risk in individuals with chronic HBV infection, written in English. We extracted data for meta-analysis and generated pooled effect estimates from a fixed-effects model. Pooled estimates from a random-effects model were also generated if significant heterogeneity was present. We identified 40 observational studies reporting on associations of diabetes mellitus (DM), hypertension, dyslipidaemia and obesity with HCC risk. Only DM had a sufficient number of studies for meta-analysis. DM was associated with >25% increase in hazards of HCC (fixed-effects hazards ratio [HR] 1.26, 95% confidence interval (CI) 1.20-1.32, random-effects HR 1.36, 95% CI 1.23-1.49). This association was attenuated towards the null in a sensitivity analysis restricted to studies adjusted for metformin use. In conclusion, in adults with chronic HBV infection, DM is a significant risk factor for HCC, but further investigation of the influence of antidiabetic drug use and glycaemic control on this association is needed. Enhanced screening of individuals with HBV and diabetes may be warranted.

Abstract
Purpose In interferon-free era, direct-acting antiviral agents (DAAs) have achieved high eradication rates with an excellent safety profile since revolutionized the management of hepatitis c virus (HCV) patients. Published papers have suggested a possible increased incidence of hepatocellular carcinoma (HCC) after successful DAAs treatment. Other papers have been published about the problem but without conclusive results. Because of this debate, we aim to evaluate the effects of antiviral therapy (Sofosbuvir plus Daclatasvir with or without Ribavirin) on the de novo occurrence of HCC in patients with liver cirrhosis (LC). Patients and Methods A prospective cohort study has included 350 patients who have visited our center for HCV treatment. Pretreatment history, examination, complete blood picture, liver function tests, kidney function tests, HA1C for diabetic patients, HCV PCR, HBsAg, alpha-fetoprotein (AFP), and abdominal ultrasound have been done, also Child-Pogh (CP) and Model for End-Stage Liver Disease (MELD) score before treatment. These investigations have been repeated for 3 months after the end of treatment. Abdominal ultrasound (US) has been done for 3 months after treatment and every 4 months for 2 years after the end of treatment to detect HCC occurrence. Results Patients age (58.11 ± 7.48), 55.4% of patients were males, 30.3% of patients were diabetic, 84.3% of them were treatment naïve and sustained virological response (SVR) occured in 94% of them. HCC occurrence after treatment was 6.7% in patients with SVR and 23.8% in patients with non-SVR (P value=0.016) during follow-up period. There is significant improvement of CP score. No significant changes in MELD score. Conclusion Treatment of HCV-related LC patients with sofosbuvir and daclatasvir with or without ribavirin for 3 or 6 months showed high SVR and significant improvement in CP score, but still at risk of HCC even if treated and should be followed up regularly according to screening programs with special meticulous attention to those with non-SVR.

Abstract
PURPOSE Hepatitis C virus (HCV) infection is the prevalent risk factor for chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC) worldwide. The association between metabolic syndrome (MetS) and HCV infection has not been studied effectively, particularly among different ethnic/racial groups in the US. METHODS A retrospective cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey (1999-2014). Unadjusted and adjusted associations were summarized using the prevalence ratio (PR) and 95% confidence interval (CI) after exploring possible interactions. RESULTS In the overall population, MetS was significantly associated with HCV infection with an interaction of age. After adjusting for all potential confounders, MetS was found to be significantly associated with HCV among non-obese and younger adults of age less than 60 years (PR 1.67, 95% CI 1.21-2.30, p = 0.002). MetS was also associated with an increased prevalence of HCV in each racial/ethnic group, while the association was strongly modified by age and obesity status of the subjects in different ethnic/racial groups. CONCLUSIONS MetS or its components are associated with an increased prevalence of HCV in some sub-populations of all ethnic/racial groups in the US. A better understanding of the pathophysiology of MetS associated with HCV is important as MetS may have a role in HCV infection treatment outcomes.

Abstract
Type 2 diabetes mellitus (T2DM) has been identified as an extrahepatic manifestation of chronic HCV infection. Conversely, in the context of chronic HCV infection, T2DM can accelerate the course of HCV-induced liver disease leading to increased risk of fibrosis, cirrhosis and hepatocellular carcinoma. The presence of T2DM negatively impacts the efficacy of interferon-based antiviral therapy, but real-world data with high-efficacy direct-acting antiviral therapies suggest high viral clearance rates in T2DM patients. In HCV-infected individuals, viral eradication is associated with a reduced risk of de novo T2DM in non-diabetic patients and beneficial metabolic changes in patients with T2DM, highlighting the importance of antiviral treatment and physician awareness of this association.

Abstract
Type 2 diabetes mellitus (T2DM) is an endocrine disorder encompassing multifactorial mechanisms, and chronic hepatitis C virus infection (CHC) is a multifaceted disorder, associated with extrahepatic manifestations, including endocrinological disorders. CHC and T2DM are associated, but the subject remains controversial. We performed a systematic review and meta-analysis evaluating such association, searching on PubMed until February 29, 2016. Inclusion criteria were: 1) presence of at least one internal control group age- and gender-matched (non-hepatopathic controls; and/or hepatopathic, not HCV-positive, controls); 2) sufficient data to calculate odds ratio and relative risk. Exclusion criteria were: 1) literature reviews on the topic; 2) publications regarding special populations [human immunodeficiency virus and human T-lymphotropic virus-1 coinfections, hepatocellular carcinoma (HCC), post-transplantation DM, gender selection]; 3) no clear differentiation among HCV patients with CHC, cirrhosis or HCC. Data from each study were independently extracted by two reviewers and cross-checked by AA. Our systematic review returned 544 records, and 33 were included in our meta-analysis. HCV infection is associated with an increased risk of T2DM independently from the severity of the associated liver disease, in CHC and cirrhotic HCV patients. As expected T2DM risk is higher in cirrhotic HCV patients, than CHC, and the prevalence of HCV infection in T2DM patients is higher than in non-diabetic controls. Regarding HBV infection prevalence, no difference exists in diabetic and non-diabetic subjects. An unequivocal CHC and T2DM association was shown. A proactive, integrated approach to HCV and T2DM therapies should maximize benefits of both diseases treatment.

Abstract
Background: There is an increasing concern about the relation between hepatitis C virus infection (HCV) and type 2 diabetes mellitus (T2DM). The present study aims to determine the prevalence of HCV infection among T2DM patients and non-diabetic patients attending primary healthcare centers (PHCCs) in Abha city, southwestern Saudi Arabia, and to explore the possible association between T2DM and HCV infection. Methods: A cross-sectional study targeting a random sample of T2DM and non-diabetic patients attending PHCCs in Abha City was conducted. Patients were interviewed using a structured questionnaire and screened for HCV infection using fourth-generation ELISA kits. All positive cases were confirmed by qualitative RT-PCR immune assay. Results: The study revealed an overall seroprevalence of HCV infection of 5% (95% CI: 2.9–7.9%). Among T2DM and non-diabetics, a seroprevalence of 8.0% and 2.0% was found, respectively. Using multivariable regression analysis, the only significant associated factor for HCV infection was T2DM (aOR = 4.185, 95% CI: 1.074–16.305). Conclusions: There is strong positive association between T2DM and HCV infection. Yet, the direction of relationship is difficult to establish. Patients with T2DM have higher prevalence of HCV infection than non-diabetic group. It is highly recommended for primary health care providers to screen for HCV infection among T2DM patients and to increase the level of HCV awareness among them.

Abstract
Hepatitis C virus (HCV) infection results in not only chronic hepatitis and subsequent complications as liver cirrhosis and hepatocellular carcinoma, but also in a significant number of other diseases, the so-called extrahepatic manifestations of chronic HCV infection. In addition to lymphoproliferative and autoimmune disorders discussed in Part 1 of this review, many other diseases turned to be associated with chronic HCV infection. Part 2 of this review is dedicated to the analysis of the relationship of chronic HCV-infection to the development of some endocrine diseases, such as thyroiditis and diabetes mellitus, and cardiovascular disorders. It also provides the characteristics of the currently available antiviral agents and considers whether they may be used in patents with extrahepatic manifestations of chronic HCV infection.

Abstract
BACKGROUND Both human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections have been reportedly associated with a higher risk of diabetes mellitus (DM) but results are conflicting. AIMS To determine whether there is an association between chronic HCV and the incidence of DM, and to study the role of factors such as cirrhosis, IFN-based HCV therapy, sustained virologic response (SVR) and chronic HBV infection among patients living with HIV (PLHIV) followed in a large French multicentre cohort in the combination antiretroviral therapy (cART) era. METHODS All PLHIV followed up in the Dat'AIDS cohort were eligible. Cox models for survival analysis were used to study the time to occurrence of DM. RESULTS Among 28 699 PLHIV, 4004 patients had chronic HCV infection. The mean duration of HCV follow-up was 12.5 ± 8.1 years. The rate ratio of DM was 2.74 per 1000 person-years. By multivariate analysis, increasing age, body mass index>25, AIDS status, nadir CD4 cell count ≤200/mm3 , detectable HIV viral load and cirrhosis (HR 2.26 95% CI 1.14-1.18; P < 0.0001) were predictors of DM, whereas longer cART duration was associated with a lower risk of DM. Chronic HCV and HBV infection and IFN-based HCV therapy were not associated with DM. In a subanalysis among HCV-infected patients, SVR was not related to DM. CONCLUSIONS Our study shows that in the HIV population, cirrhosis is associated with an increased occurrence of DM, but not chronic HCV infection or duration of HCV infection.

Abstract
<b><i>Background:</i></b> The ever-increasing global prevalence of hepatitis C infection is fueling the burden of diabetes mellitus, which exacerbates various complications and may be a cause of death of millions of people. Several studies have reported that hepatitis C virus infection is an important risk factor for the development of diabetes mellitus. However, fragmented studies have reported variable and inconsistent findings regarding the prevalence of type 2 diabetes mellitus among hepatitis C virus-infected patients. Therefore, this meta-analysis aimed to estimate the overall prevalence of type 2 diabetes mellitus among patients infected with hepatitis C virus. <b><i>Methods:</i></b> This systematic review and meta-analysis includes original articles reporting on cohort and cross-sectional studies. A systematic search was performed in PubMed, ScienceDirect, and Google Scholar. A random-effects meta-analysis model was used to estimate the global pooled prevalence of type 2 diabetes mellitus among hepatitis C-infected patients. A sensitivity analysis was conducted to check the stability of the summary estimate. Heterogeneity was assessed using the <i>I</i><sup>2</sup> statistic. A subgroup analysis was also conducted based on geographical region. Funnel plots were used to spot publication bias. <b><i>Results:</i></b> A total of 40 eligible articles reporting data on 14,765 study participants were included in this meta-analysis. The pooled prevalence of type 2 diabetes mellitus among hepatitis C virus-infected patients was 19.67% (95% CI: 17.25, 22.09). The subgroup analysis showed a pooled prevalence of 27.72% (95% CI: 20.79, 34.65) in Africa, 20.73% (95% CI: 17.57, 23.90) in Asia, 16.64% (95% CI: 6.79, 26.49) in North America, and 15.02% (95% CI: 10.66, 19.38) in Europe. <b><i>Conclusions:</i></b> The overall prevalence of type 2 diabetes mellitus among hepatitis C virus-infected patients was considerably higher than in the general population in a global perspective. The highest prevalence was noted in Africa and Asia, followed by North America and Europe. Therefore, early intervention is needed (prevention and early treatment of hepatitis C virus infection) to prevent the development of type 2 diabetes mellitus.

Abstract
BACKGROUND Because whether hepatitis B virus infection increases the risk of type 2 diabetes mellitus has been a controversial topic, pair-wise and network meta-analyses of published literature were carried out to accurately evaluate the association between different phases of hepatitis B virus infection and the risk of type 2 diabetes mellitus. METHODS A comprehensive literature retrieval was conducted from the PubMed, Embase, Cochrane Library and Chinese Database to identify epidemiological studies on the association between hepatitis B virus infection and the risk of type 2 diabetes mellitus that were published from 1999 to 2015. A pair-wise meta-analysis of direct evidence was performed to estimate the pooled odds ratios and 95% confidence intervals. A network meta-analysis was conducted, including the construction of a network plot, inconsistency plot, predictive interval plot, comparison-adjusted funnel plot and rank diagram, to graphically link the direct and indirect comparisons between different hepatitis B virus infective phases. RESULTS Eighteen publications (n=113 639) describing 32 studies were included in this meta-analysis. In the pair-wise meta-analysis, the pooled odds ratio for type 2 diabetes mellitus in chronic hepatitis B cirrhosis patients was 1.76 (95% confidence interval: 1.44-2.14) when compared with non-cirrhotic chronic hepatitis B patients. In the network meta-analysis, six comparisons of four hepatitis B virus infectious states indicated the following descending order for the risk of type 2 diabetes mellitus: hepatitis B cirrhosis patients, non-cirrhotic chronic hepatitis B patients, hepatitis B virus carriers and non-hepatitis B virus controls. CONCLUSION This study suggests that hepatitis B virus infection is not an independent risk factor for type 2 diabetes mellitus, but the development of cirrhosis may increase the incidence of type 2 diabetes mellitus cirrhosis.

Abstract
The role of hepatitis virus infection in glucose homeostasis is uncertain. We examined the associations between hepatitis B virus (HBV) or hepatitis C virus (HCV) infection and the development of diabetes in a cohort (N = 439,708) of asymptomatic participants in health screening examinations. In cross-sectional analyses, the multivariable-adjusted odds ratio for prevalent diabetes comparing hepatitis B surface antigen (HBsAg) (+) to HBsAg (−) participants was 1.17 (95% CI 1.06–1.31; P = 0.003). The corresponding odds ratio comparing hepatitis C antibodies (HCV Ab) (+) to HCV Ab (−) participants was 1.43 (95% CI 1.01–2.02, P = 0.043). In prospective analyses, the multivariable-adjusted hazard ratio for incident diabetes comparing HBsAg (+) to HbsAg (−) participants was 1.23 (95% CI 1.08–1.41; P = 0.007). The number of incident cases of diabetes among HCV Ab (+) participants (10 cases) was too small to reliably estimate the prospective association between HCV infection and diabetes. In this large population at low risk of diabetes, HBV and HCV infections were associated with diabetes prevalence and HBV infection with the risk of incident diabetes. Our studies add evidence suggesting that diabetes is an additional metabolic complication of HBV and HCV infection.

Abstract
BACKGROUND The risks for transplant outcomes associated with baseline viral serostatus in kidney transplant recipients (KTR) on sirolimus have not been widely studied. METHODS We performed a cohort-study of 61 590 adult KTR in 2000 to 2013. We used Cox regression models to determine the adjusted hazard ratio (aHR) of patient death, death-censored graft loss and posttransplant malignancy associated with the baseline serostatus (+ or -: hepatitis B core [HBc], hepatitis C virus [HCV], Epstein-Barr virus [EBV], or cytomegalovirus [CMV]) in KTR on sirolimus (SRL) + mycophenolate (MPA) or SRL + tacrolimus (Tac), relative to the control-regimen: Tac + MPA. RESULTS Compared with Tac + MPA, SRL + MPA, and SRL + Tac were associated with higher risks of 5-year mortality (aHR, 1.41; 95% CI, 1.23-1.60 and aHR, 1.59; 95% CI, 1.38-1.83, respectively) and death-censored graft loss (aHR, 1.41; 95% CI, 1.24-1.60 and aHR, 1.38; 95% CI, 1.21-1.57, respectively). In KTR with negative pretransplant EBV, CMV, HBc, or HCV serostatus, SRL + MPA not SRL + Tac was associated with a lower risk of posttransplant malignancy compared with control (aHR, 0.27; 95% CI, 0.10-0.72; aHR, 0.61; 95% CI, 0.43-0.88; aHR, 0.79; 95% CI, 0.64-0.97; and aHR, 0.80; 95% CI, 0.65-0.98, respectively, for SRL + MPA and aHR, 0.98: 95% CI, 0.52-1.80; aHR, 0.69; 95% CI, 0.46-1.06; aHR, 0.83; 95% CI, 0.66-1.06 and aHR, 0.85; 95% CI, 0.67-1.07, respectively, for SRL + Tac). In KTR with positive serostatus to any of the above viruses, SRL + MPA or SRL + Tac was not associated with a different malignancy risk compared with control. CONCLUSIONS Compared with Tac + MPA, SRL regimens were associated with higher risks for patient death and graft loss, although SRL + MPA was associated with a lower risk for posttransplant malignancy in kidney allograft recipients with negative pretransplant HBc, HCV, EBV, or CMV serology.

Abstract
The association between hepatitis C virus (HCV) infection and type 2 diabetes (T2D) has been known for over 20 years. Cross-sectional and longitudinal studies have shown a higher prevalence and incidence, respectively, of T2D in patients with chronic HCV infection. HCV induces glucose metabolism alterations mostly interfering with the insulin signaling chain in hepatocytes, although extrahepatic mechanisms seem to contribute. Both IR and T2D accelerate the histological and clinical progression of chronic hepatitis C as well as the risk of extra-hepatic complications such as nephropathy, acute coronary events and ischemic stroke. Before the availability of direct-acting antivirals (DAAs), the therapeutic choice was limited to interferon (IFN)-based therapy, which reduced the incidence of the extra-hepatic manifestations but was burdened with several contraindications and poor tolerability. A better understanding of HCV-associated glucose metabolism derangements and their reversibility is expected with the use of DAAs.

Abstract
Viral hepatitis has been posited to play a role in the development of type 2 diabetes. Thus, prevention of viral hepatitis through vaccination has the potential to reduce the burden of type 2 diabetes. We have shown that successful hepatitis B vaccination reduces the risk of diabetes by 33 %. Although diabetes can be prevented by behavior modification and pharmaceutical agents, these require significant personal commitment and cost. In contrast, diabetes prevention through hepatitis B vaccination would require little personal commitment and relatively low cost. In this review, we discuss hepatitis viruses A, B, and C and their interaction with diabetes; explore the potential underlying mechanisms and potential for hepatitis vaccination to reduce diabetes; and estimate the medical expense savings that would result from such an intervention. Given the projected increase of diabetes prevalence in the developing regions, where hepatitis B is endemic, exploration of such an intervention is very timely.

Abstract
Hepatitis C virus (HCV) infection is responsible for both hepatic and extra-hepatic disorders (HCV-EHDs); these latter are correlated on one hand clearly with HCV lymphotropism causing immune-system dysregulation as well as with viral oncogenic potential, and on the other hand probably with chronic inflammatory status causing cardio-metabolic complications as well as neurocognitive disturbances. The spectrum of HCV-EHDs ranges from mild or moderate manifestations, such as arthralgia, sicca syndrome, peripheral neuropathy, to severe, life-threatening complications, mainly vasculitis and neoplastic conditions. Given the clinical heterogeneity of HCV-EHDs, HCV-infected individuals are inevitably referred to different specialists according to the presenting/prevalent symptom(s); therefore, the availability of comprehensive diagnostic guidelines is necessary for a patient's whole assessment that is decisive for early diagnosis and correct therapeutic approach of various hepatic and HCV-EHDs, regardless of the specific competencies of different physicians or referral centers. In this respect, a multidisciplinary network of experts, the International Study Group of Extrahepatic Manifestations Related to Hepatitis C Virus Infection (ISG-EHCV), was organized with the intention to formulate diagnostic guidelines for the work-up of possible HCV-EHDs. There was a broad consensus among ISG-EHCV members on the proposed guidelines, which essentially are based on two main levels of patient's assessment. At the referral stage, it is proposed that all patients with HCV infection should be invariably examined by means of first-line diagnostic procedures including virological and hepatic parameter evaluation, as well as the detection of clinical findings that may suggest one or more HCV-EHDs. This preliminary assessment should reveal specific HCV-EHDs, which will be deeper analyzed by means of second-line, targeted investigations. The proposed multidisciplinary expert statement represents the first attempt to draw comprehensive diagnostic guidelines for HCV-infected individuals encompassing the entire spectrum of HCV-related disorders, namely typical hepatic manifestations along with less common, often unpredictable HCV-EHDs. The HCV-EHDs may compromise to a substantial degree the overall disease outcome in a significant number of HCV-infected individuals that renders their timely identification and treatment an imperative. In conclusion, the application of standardized but thorough diagnostic guidelines of HCV-EHDs is advisable at the referral stage as well as during the follow-up period of HCV infected patients. It is envisioned that the proposed strategy will result in improvement of clinical outcomes in such patients.

Abstract
Background and Objectives Tick-borne encephalitis (TBE) still represents a considerable medical and health economic problem in Europe and entails a potential threat to travellers. The aim of this study was to characterise the conditions of severe TBE by precisely recording its clinical variants, the related neuroimaging features, and the variant-specific long-term outcome and by identifying predictors for severe courses. Methods A cohort of 111 TBE patients (median age 51, range 17–75 years; 42% females) was analysed prospectively. Data were acquired from the department of neurology, University Hospital Heidelberg, and the infectious diseases registry of the Robert-Koch institute Berlin. Neurological status was ascertained by protocol at admission and discharge and the degree of disability was scored using the modified RANKIN Scale (mRS; clinical score addressing neurological disability, range from 0, healthy to 6, dead) at admission and at follow-up. Follow-up examination was conducted by means of a telephone interview. To identify independent predictors for severe TBE and functional outcome, modelled logistic regression was performed. MRI changes were correlated with infection variants. To assess alpha-motor neuron injury patterns, we used high-resolution magnetic resonance neurography (hrMRN). Analyses were performed at the Department of Neurology, University Hospital, University of Heidelberg from April 2004 through September 2014 Results Acute course: 3.6% of patients died during the acute infection. All patients with a lethal course suffered from meningoencephaloradiculitis (MER, 14.4% of the cohort), which is associated with a significantly higher risk of requiring intensive care (p = 0.004) and mechanical ventilation (p<0.001) than menigoencephalitis (ME, 27.9% of the cohort). At admission, both MER and ME groups were severely affected, with the MER group having a statistically higher mRS score (median of 5 in the MER groups versus 4 in the ME group; p<0.001). Long-term outcome: outcome for MER was considerably worse (median mRS = 4) than for ME (mRS = 1, p<0.0001) and meningitis (mRS = 0, 57.7% of the cohort). Risk factors: advanced age (p<0.001) and male gender (p = 0.043) are independent risk factors for a severe infection course. Furthermore, we identified pre-existing diabetes mellitus (p = 0.024) as an independent risk factor for MER. In MER, alpha-motor neuron injury accounts for the poor prognosis confirmed by hrMRN. Conclusion and Relevance These data provide critical information for neurologists and other health professionals to use in evaluating TBEV patients who live in or travel to endemic areas. This information can be used to classify clinical presentation and estimate infection-associated complications and individual prognosis. Furthermore, the risk for severe, disabling infections in older patients should prompt general practitioners to recommend and encourage vaccination to those patients living in or travelling to endemic areas.

Abstract
Hereditary type 2 diabetes mellitus is a risk factor for chronic liver disease, and ~30 % of patients with liver cirrhosis develop diabetes. Diabetes mellitus has been associated with cirrhotic and non-cirrhotic hepatitis C virus liver infection, can aggravate the course the liver infection, and can induce a lower sustained response to antiviral treatment. Evidences that HCV may induce metabolic and autoimmune disturbances leading to hypobetalipoproteinemia, steatosis, insulin resistance, impaired glucose tolerance, thyroid disease, and gonadal dysfunction have been found. Prospective studies have demonstrated that diabetes increases the risk of liver complications and death in patients with cirrhosis. However, treatment of diabetes in these patients is complex, as antidiabetic drugs can promote hypoglycemia and lactic acidosis. There have been few therapeutic studies evaluating antidiabetic treatments in patients with liver cirrhosis published to date; thus, the optimal treatment for diabetes and the impact of treatment on morbidity and mortality are not clearly known. As numbers of patients with chronic liver disease and diabetes mellitus are increasing, largely because of the global epidemics of obesity and nonalcoholic fatty liver disease, evaluation of treatment options is becoming more important. This review discusses new concepts on hepatogenous diabetes, the diabetes mellitus–hepatitis C virus association, and clinical implications of diabetes mellitus in patients with chronic liver disease. In addition, the effectiveness and safety of old and new antidiabetic drugs, including incretin-based therapies, will be described.

Abstract
The major advances achieved in the treatment of HCV by the development of new direct-acting antiviral agents (DAAs) allow treatment of almost the entire spectrum of patients with chornic infection. As a result of the exceedingly high cost of DAAs in many countries, IFN-free DAA regimens are mostly reserved to patients with advanced fibrosis or cirrhosis. Hence, treatment of patients with milder liver disease is often deferred. This could ultimately result in an increased burden of advanced liver disease and in increased long-term costs of management. Moreover, studies performed during the 'interferon era' and the early data on interferon-free regimens show that patients without severe fibrosis achieve higher rates of sustained virological response with less treatment-related adverse events. Unfortunately, there is no univocal way to predict the progression of liver fibrosis and therefore to identify the patients with early disease who would require urgent HCV treatment. Many studies have also demonstrated that treatment-induced HCV clearance reduces all-cause mortality regardless of the stage of liver fibrosis, pointing to an effect on extrahepatic manifestations of HCV infection. Last but not least, pharmacoeconomic studies show that DAA treatment of patients with mild HCV disease is cost-effective even at high prices of drugs, thus suggesting the opprtunity to treat regardless of the stage of liver disease.

Abstract
This study aimed to estimate the prevalence and risk factors for hepatitis C virus (HCV) infection in Mexican Americans living in South Texas. We tested plasma for the presence of HCV antibody from the Cameron County Hispanic Cohort (CCHC), a randomized, population-based cohort in an economically disadvantaged Mexican American community on the United States/Mexico border with high rates of chronic disease. A weighted prevalence of HCV antibody of 2·3% [n = 1131, 95% confidence interval (CI) 1·2-3·4] was found. Participants with diabetes had low rates of HCV antibody (0·4%, 95% CI 0·0-0·9) and logistic regression revealed a statistically significant negative association between HCV and diabetes (OR 0·20, 95% CI 0·05-0·77) after adjusting for sociodemographic and clinical factors. This conflicts with reported positive associations of diabetes and HCV infection. No classic risk factors were identified, but important differences between genders emerged in analysis. This population-based study of HCV in Mexican Americans suggests that national studies do not adequately describe the epidemiology of HCV in this border community and that unique risk factors may be involved.

Abstract
Patients with chronic hepatitis C virus (HCV) infection frequently present with extrahepatic manifestations covering a large spectrum, involving different organ systems leading to the concept of systemic HCV infection. These manifestations include autoimmune phenomena and frank autoimmune and/or rheumatic diseases and may dominate the course of chronic HCV infection. Chronic HCV infection causes liver inflammation affecting the development of hepatic diseases. HCV is also a lymphotropic virus that triggers B cells and promotes favorable conditions for B lymphocyte proliferation, including mixed cryoglobulinemia (MC) and MC vasculitis, which is the most prominent extrahepatic manifestation of chronic HCV infection. HCV may also promote a low-grade chronic systemic inflammation that may affect the development of some extrahepatic manifestations, particularly cardiovascular and cerebral vascular diseases. Recognition of extrahepatic symptoms of HCV infection could facilitate early diagnosis and treatment. The development of direct-acting antiviral agents (DDAs) has revolutionized HCV treatment. DDAs, as well as new B-cell-depleting or B-cell-modulating monoclonal antibodies, will expand the panorama of treatment options for HCV-related extrahepatic manifestations including cryoglobulinemic vasculitis. In this context, a proactive, integrated approach to HCV therapy should maximize the benefits of HCV therapy, even when liver disease is mild.

Abstract
Many studies have demonstrated a potential association between type 2 diabetes (T2D) and hepatitis C virus infection in Western countries, while similar evidence is limited in Asia. We compared the prevalence of glucose abnormalities (impaired fasting glucose [IFG] and T2D) and their risk factors between Asian and non-Asian chronic hepatitis C (CHC) patients, and evaluated whether glucose abnormalities impacted the viral responses to peginterferon plus ribavirin treatment (current standard of care in most Asian countries). This study retrospectively analyzed data of 1,887 CHC patients from three Phase II/III studies with alisporivir (DEB025) as treatment for CHC. The chi-square test was used to compare the prevalence of IFG/T2D between Asian and non-Asian CHC patients, and logistic regression was used to adjust for sex, age, and cirrhosis status. Risk factors for IFG/T2D were evaluated using univariate and multivariate analysis. Our results indicated that the prevalence of IFG/T2D was high in both Asian and non-Asian CHC patients (23.0% vs 20.9%), and no significant difference was found between these two populations (adjusted odds ratio: 1.3, 95% confidence interval: 0.97, 1.7; P=0.08). Age, sex, and cirrhosis status were risk factors for IFG/T2D in both populations, while body mass index was positively associated with IFG/T2D in non-Asian but not in Asian participants. No significant differences in sustained virological response rates were seen between patients with normal fasting glucose and patients with IFG/T2D for both populations. These results demonstrate that the prevalence of glucose abnormalities in Asian CHC patients was similar to that in non-Asians, and glucose abnormalities had no impact on viral response to peginterferon plus ribavirin.

Abstract
AIM Whether hepatitis B virus (HBV) infection increases the risk of type 2 diabetes mellitus (T2DM) is controversial. We carried out a meta-analysis to evaluate the association between HBV infection status and the risk of T2DM. METHODS The PubMed, Embase and Ovid databases were searched for relevant studies on an association between HBV infection and the risk of diabetes. Methodological quality was assessed using the adapted Newcastle-Ottawa Quality Assessment Scale. A fix- or random-effects model was used to summarize odd ratios (OR) and 95% confidence intervals (CI). RESULTS We included seven cohort studies, four case-control and four cross-sectional studies, involving 118 530 participants. The prevalence of T2DM differs by HBV infection status. Pooled estimators indicated a nearly twofold excess T2DM risk with hepatitis B cirrhosis (HBC) status. The summary OR of the risk of T2DM for HBC patients was 1.99 (95% CI, 1.08-3.65) when compared with the non-HBV individuals, and 1.74 (95% CI, 1.43-2.13) when compared with non-cirrhotic chronic hepatitis B (NC-CHB) patients. In contrast, no significant correlation was found between asymptomatic HBV carriers or NC-CHB patients and the incidence of diabetes, compared with non-HBV controls. CONCLUSION Our findings suggest that while HBV itself may not be pro-diabetic, the HBV-derived cirrhosis is an independent risk factor for T2DM.

Abstract
HCV chronic infection is characterized by possible development of both hepatic and extrahepatic manifestations. The infection by this both hepatotropic and lymphotropic virus is responsible for polyoligoclonal B-lymphocyte expansion, leading to several immune-mediated disorders. Mixed cryoglobulinemia syndrome that in some cases may evolve to frank B-cell non-Hodgkin's lymphoma is the prototype of HCV-driven autoimmune and lymphoproliferative disorders. The HCV oncogenic potential has been suggested by several clinicoepidemiological and laboratory studies; it includes hepatocellular carcinoma, B-cell non-Hodgkin's lymphoma and papillary thyroid cancer. The definition HCV syndrome refers to the complex of HCV-driven diseases; these latter are characterized by heterogeneous geographical distribution, suggesting a role of other important genetic and/or environmental cofactors. The natural history of HCV syndrome is the result of a multifactorial and multistep pathogenetic process, which may evolve from mild manifestations to systemic autoimmune disorders, and less frequently to malignant neoplasias. The present updated review analyzes the clinical and pathogenetic aspects of the main HCV-associated diseases.

Abstract
Cytokines are intercellular mediators involved in viral control and liver damage being induced by infection with hepatitis C virus (HCV). The complex cytokine network operating during initial infection allows a coordinated, effective development of both innate and adaptive immune responses. However, HCV interferes with cytokines at various levels and escapes immune response by inducing a T-helper (Th)2/T cytotoxic 2 cytokine profile. Inability to control infection leads to the recruitment of inflammatory infiltrates into the liver parenchyma by interferon (IFN)-γ-inducible CXC chemokine ligand (CXCL)9, -10, and -11 chemokines, which results in sustained liver damage and eventually in liver cirrhosis. The most important systemic HCV-related extrahepatic diseases-mixed cryoglobulinemia, lymphoproliferative disorders, thyroid autoimmune disorders, and type 2 diabetes-are associated with a complex dysregulation of the cytokine/chemokine network, involving proinflammatory and Th1 chemokines. The therapeutical administration of cytokines such as IFN-α may result in viral clearance during persistent infection and revert this process. Theoretically agents that selectively neutralize CXCL10 could increase patient responsiveness to traditional IFN-based HCV therapy. Several studies have reported IL-28B polymorphisms and circulating CXCL10 may be a prognostic markers for HCV treatment efficacy in HCV genotype 1 infection.

Abstract
The role of interleukin (IL) 28B in the treatment of chronic hepatitis C (CHC) has recently been examined in many studies, while a possible relationship between IL28B and the presence of mixed cryoglobulinemia (MC) remains to be clarified. In this study, we analyzed the influence of IL28B rs8099917/rs12979860 on the presence of MC and the role in treatment with PEG-IFN. We retrospectively examined 541 patients affected by CHC who were treated with pegylated interferon (PEG-IFN) and ribavirin from 2003 to 2012. We included all treatment-naïve patients without other viral co-infections or major contraindications to the PEG-IFN and ribavirin standard of care. One hundred seventy-five patients (32.3 %) had MC; 49 of these (33.3 %) had symptomatic MC. The IL28B rs8099917/rs12979860 TT/CC genotype was the most frequent in MC-positive patients with sustained virological response (SVR) (p < 0.001), while the TG/TC genotype was most frequent in non-SVR (p < 0.001). The TT/CC genotype was found to be the main positive predictive factor of MC in HCV patients (OR = 11.914; IQR = 7.092-18.776; p < 0.001); HCV genotype 2/3 was the strongest positive predictive factor of SVR (OR = 10.448; IQR = 8.352-21.561; p < 0.001); IL28B rs8099917/rs12979860 TT/CC was a better predictive factor than rs12979860 CC alone (OR = 9.829 vs. 2.663). Negative predictive factors were Metavir score F3-F4 (OR = 0.625; IQR = 0.416-0.779; p = 0.008), insulin-resistance (OR = 0.315; IQR = 0.224-0.585; p < 0.001) and presence of symptoms (OR = 0.716; IQR = 0.492-0.855; p < 0.001). IL28B rs8099917/rs12979860 is useful in the treatment of MC-positive HCV patients with PEG-IFN and ribavirin; the TT/CC genotype is associated with SVR, the TG/TC with non-SVR; TT/CC is also predictive of MC in HCV patients.

Abstract
INTRODUCTION Hepatitis C is an emerging disease with different studies showing varying prevalence rates across India. In several studies, prevalence of hepatitis C infection was found to be higher in diabetics than nondiabetics. However, none has been reported from India. OBJECTIVES The aim was to determine the sero-prevalence of hepatitis C infection in type 2 diabetes mellitus (T2DM). SETTINGS AND DESIGN Cross-sectional study of all T2DM patients attending endocrine clinic in Regional Institute of Medical Sciences, Imphal from October 2011 to September 2013. SUBJECTS AND METHODS All T2DM patients included and exclusion criteria are patients with other forms of diabetes, liver failure, renal failure, malignancy or other chronic illness. Patient's age, sex, height, weight, body mass index, history of risk factors, etc., collected and investigated for blood glucose fasting and prandial levels, transaminases levels, hepatitis C virus (HCV) screening, etc.. STATISTICAL ANALYSIS Statistical analysis was performed using Statistical Package for the Social Sciences version 20; appropriate test used where applicable. RESULTS Out of the 192 T2DM patients screened, prevalence rate of HCV sero-positivity is found to be 5.7% (11/192), higher in males. History of jaundice in the past was the only significant history among sero-positive patients. Transaminases levels are significantly higher in sero-postive cases. They had higher fasting and postprandial blood glucose, fasting glucose levels being significantly higher. CONCLUSION Our study shows a slightly higher prevalence of hepatitis C infection in type 2 diabetics.

Abstract
Diabetes and hepatitis C infection are both prevalent diseases worldwide, and are associated with increased morbidity and mortality. Most studies, but not all, have shown that patients with chronic hepatitis C are more prone to develop type 2 diabetes (T2D) compared to healthy controls, as well as when compared to patients with other liver diseases, including hepatitis B. Furthermore, epidemiological studies have revealed that patients with T2D may also be at higher risk for worse outcomes of their hepatitis C infection, including reduced rate of sustained virological response, progression to fibrosis and cirrhosis, and higher risk for development of hepatocellular carcinoma. Moreover, hepatitis C infection and mainly its treatment, interferon α, can trigger the development of type 1 diabetes. In this review, we discuss the existing data on this two-way association between diabetes and hepatitis C infection with emphasis on possible mechanisms. It remains to be determined whether the new curative therapies for chronic hepatitis C will improve outcomes in diabetic hepatitis C patients, and conversely whether treatment with Metformin will reduce complications from hepatitis C virus infection. We propose an algorithm for diabetes screening and follow-up in hepatitis C patients.

Abstract
Hepatitis C virus (HCV) infection and diabetes mellitus are two major public health problems that cause devastating health and financial burdens worldwide. Diabetes can be classified into two major types: type 1 diabetes mellitus (T1DM) and T2DM. T2DM is a common endocrine disorder that encompasses multifactorial mechanisms, and T1DM is an immunologically mediated disease. Many epidemiological studies have shown an association between T2DM and chronic hepatitis C (CHC) infection. The processes through which CHC is associated with T2DM seem to involve direct viral effects, insulin resistance, proinflammatory cytokines, chemokines, and other immune-mediated mechanisms. Few data have been reported on the association of CHC and T1DM and reports on the potential association between T1DM and acute HCV infection are even rarer. A small number of studies indicate that interferon-α therapy can stimulate pancreatic autoimmunity and in certain cases lead to the development of T1DM. Diabetes and CHC have important interactions. Diabetic CHC patients have an increased risk of developing cirrhosis and hepatocellular carcinoma compared with non-diabetic CHC subjects. However, clinical trials on HCV-positive patients have reported improvements in glucose metabolism after antiviral treatment. Further studies are needed to improve prevention policies and to foster adequate and cost-effective programmes for the surveillance and treatment of diabetic CHC patients.

Abstract
Type 1 diabetes (T1D) is due to antigen-specific assaults on the insulin producing pancreatic β-cells by diabetogenic T-helper (Th)1 cells. (C-X-C motif) ligand (CXCL)10, an interferon-γ inducible Th1 chemokine, and its receptor, (C-X-C motif) receptor (CXCR)3, have an important role in different autoimmune diseases. High circulating CXCL10 levels were detected in new onset T1D patients, in association with a Th1 autoimmune response. Furthermore β-cells produce CXCL10, under the influence of Th1 cytokines, that suppresses their proliferation. Viral β-cells infections induce cytokines and CXCL10 expression, inducing insulin-producing cell failure in T1D. CXCL10/CXCR3 system plays a critical role in the autoimmune process and in β-cells destruction in T1D. Blocking CXCL10 in new onset diabetes seems a possible approach for T1D treatment.

Abstract
A higher prevalence of immunological processes has recently been reported in patients with hepatitis C virus (HCV) infection, focusing the attention of physicians and researchers on the close association between HCV and immune disorders. HCV lymphotropism represents the most important step in the pathogenesis of virus-related immunological diseases and experimental, virologic, and clinical evidence has demonstrated a trigger role for HCV both in systemic autoimmune diseases, such as rheumatoid arthritis, Sjögren syndrome, hemolytic anemia and severe thrombocytopenia, and in organ-specific autoimmune diseases, such as autoimmune hepatitis, thyroid disorders and diabetes. This review will outline the principal aspects of such HCV-induced immunological alterations, focusing on the prevalence of these less characterized HCV extrahepatic manifestations.

Abstract
Until now, no study has evaluated CXCL9 in hepatitis C virus (HCV) infection-related mixed cryoglobulinemia (MC) patients in presence/absence of autoimmune thyroiditis (AT). Serum CXCL9 and CXCL10 have been measured in 60 patients with MC (MCo), in 35 patients with MC and AT (MC-AT), in sex and age-matched controls: 60 healthy (Control 1); 35 patients with AT without cryoglobulinemia (Control 2). CXCL9 and CXCL10 were higher in MC-AT patients than Control 2 (P<0.0001) and MCo (P=0.01), in MCo than Control 1 (P<0.0001), and in Control 2 than Control 1 (P<0.001). By defining a high CXCL9 level as a value>2 SD above the mean value of the Control 1 (>122 pg/mL), 5% of Control 1, 34% of Control 2, 91% of MCo, and 97% of MC+AT had high CXCL9 (P<0.0001, chi-square). By simple regression analysis CXCL9 and CXCL10 were related to each other in MCo (r=0.426, P=0.001) and in MC-AT (r=0.375, P=0.001). We first demonstrate high serum levels of CXCL9 in cryoglobulinemic patients, especially with AT. Further, a strong association between serum CXCL9 and CXCL10 has been observed in patients with MC in presence/absence of AT.

Abstract
BACKGROUND AND STUDY AIMS There is controversy regarding whether a specific hepatitis C virus (HCV) genotype is associated with diabetes mellitus. This study aimed to investigate HCV genotype distribution in diabetics and its relation to some clinical and laboratory variables in HCV-positive diabetic versus non-diabetic Egyptians in East Delta. PATIENTS AND METHODS The study included 100 HCV-positive patients of which 66 were diabetic in addition to 35 healthy adults as a control group. Clinical assessment, laboratory measurements of plasma glucose, insulin, C-peptide, C-reactive protein (CRP), tumour necrosis factor-α (TNF-α) and liver functions (alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyltransferase (GGT)) as well as HCV genotype determination were done, and AST/platelet ratio index (APRI) and Homoeostasis Model of Assessment-Insulin Resistance (HOMA-IR) were calculated. RESULTS The main results were the presence of HCV genotype 3, in 31.8% of the diabetic group and in 26.5% of the non-diabetic group, while the remainder of cases had genotype 4, the predominant genotype in Egypt. This is the first report of the presence of HCV genotype 3 in about 30% of an Egyptian cohort. However, there was no significant difference in genotype distribution between both groups. Further, there were significantly higher values of HOMA-IR, insulin and C-peptide in HCV-positive groups in comparison to the control group, while TNF-α was significantly higher in the HCV-positive diabetic group. However, there were no significant differences between both genotypes regarding these parameters. CONCLUSION Although this study reveals for the first time the presence of HCV genotype 3 in a significant percentage of a group of Egyptian patients, where the majority were diabetic, the association between diabetes and certain HCV genotypes could not be confirmed on the basis of our findings. Hence, taking into consideration the impact of such a finding on the treatment decisions of those patients, further studies are warranted to explore these findings to a greater extent.

Abstract
Hepatitis C virus (HCV) infection is one of the most important causes of cirrhosis and hepatocellular carcinoma and has a tremendous impact on public health worldwide. HCV is both hepatotropic and lymphotropic. Replication of HCV in diseased extrahepatic organs and tissues may either trigger latent autoimmunity or induce autoimmune disorders. In addition to established liver injury, type 2 diabetes mellitus (T2DM) is an important feature of extrahepatic metabolic disorders which is attributed to HCV infection. It also has some impact on the disease activity, disease course, clinical outcomes, and treatment efficacy of antiviral therapy. Previous experimental and clinical findings have highly suggested that HCV per se is diabetogenic. The cause-effect interaction between a common endocrine disorder and an infectious disease is an important issue to elucidate. Although the precise mechanisms whereby HCV infection leads to insulin resistance (IR) and glucose abnormalities are not entirely clear, it differs from the usual pathogenesis of T2DM in those with non-HCV liver diseases. This review initially highlights epidemiological and pathophysiological studies addressing the mutual link between chronic HCV infection (CHC) and T2DM. The characteristics of glucose abnormalities in this special population are depicted from the current evidence. The mutual roles of IR and CHC with respect to the prediction of treatment efficacy, how treatment response affects IR, and the role of pancreatic beta cell function in the entire suite are discussed. With the rapid progression of antiviral therapy for CHC in the past decade, we have also listed some points of future perspective in this issue.

Abstract
Diabetes and chronic liver disease (CLD) are common long-term conditions in the developed and developing world. The 2 conditions often coexist, and there is evidence to suggest that diabetes can have a significant adverse effect on patients with CLD, leading to increased complications and premature mortality. While diabetes, nonalcoholic fatty liver disease, and nonalcoholic steatohepatitis (NASH) appear to have common origins related to obesity and insulin resistance, diabetes is also common among patients with alcoholic and viral CLD. In patients with NASH, improvement in metabolic indices appears to reduce the progression of CLD. It is not clear whether improving glycemic control in other forms of CLD leads to improved outcomes. Managing diabetes in patients with CLD can be challenging because many antihyperglycemic therapies are contraindicated or must be used with care. Metformin and pioglitazone may be useful in patients with NASH, but sulfonylureas and insulin must be used with caution, as hypoglycemia may be a problem. Insulin doses frequently need to be reduced in patients with CLD. Newer glycemic agents have not been widely used in patients with CLD, but bariatric surgery may lead to significant improvement in liver indices in patients with NASH. Management of patients with diabetes and CLD may be enhanced by using a multidisciplinary approach.

Abstract
BACKGROUND AND AIMS Hepatitis C virus (HCV) infection is reported to be associated with or to cause type 2 diabetes mellitus (T2DM). Our study aimed to elucidate the role of triglyceride (TG) and cholesterol (CHOL) levels in the association between anti-HCV seropositivity and T2DM in an HCV-endemic area. METHODS We analyzed a computerized dataset of 56 338 residents from a community-based comprehensive screening program in Tainan County in southern Taiwan. Fasting glucose, anti-HCV status, hepatitis B surface antigen (HBsAg) status, platelet counts, TG levels, CHOL levels, age, gender, and body mass index were included in the analyses. Multivariate logistic analysis was used to identify factors independently associated with T2DM. RESULTS Older age, being overweight, thrombocytopenia, hypertriglyceridemia, hypercholesterolemia, anti-HCV seropositivity, and HBsAg seronegativity were common factors independently associated with diabetes. Among all models of multiple logistic regression analysis used for identifying factors independently associated with T2DM, anti-HCV seropositivity was only identified in the models that included either hypertriglyceridemia or hypercholesterolemia. When subjects were divided into hyperlipidemia (CHOL, > 200 or TG, > 150 mg/dL; n = 33 393) or non-hyperlipidemia subgroups (CHOL, < 200 and TG, < 150 mg/dL; n = 22 945), anti-HCV seropositivity was identified as an independent factor only in the non-hyperlipidemia subgroup. The odds ratio was 1.35, with a 95% confidence interval of 1.17-1.55. CONCLUSIONS This study demonstrates that the lipid level is associated with the relationship between T2DM and anti-HCV seropositivity in non-hyperlipidemic individuals. However, the relationship between HCV and T2DM did not exist when the lipid level was not included in the analysis.

Abstract
Cytokines are intercellular mediators involved in viral control and liver damage being induced by infection with hepatitis C virus (HCV). The complex cytokine network operating during initial infection allows a coordinated, effective development of both innate and adaptive immune responses. However, HCV interferes with cytokines at various levels and escapes immune response by inducing a T-helper (Th)2/T cytotoxic 2 cytokine profile. Inability to control infection leads to the recruitment of inflammatory infiltrates into the liver parenchyma by interferon (IFN)-gamma-inducible CXC chemokine ligand (CXCL)-9, -10, and -11 chemokines, which results in sustained liver damage and eventually in liver cirrhosis. The most important systemic HCV-related extrahepatic diseases--mixed cryoglobulinemia, lymphoproliferative disorders, thyroid autoimmune disorders, and type 2 diabetes--are associated with a complex dysregulation of the cytokine/chemokine network, involving proinflammatory and Th1 chemokines. The therapeutical administration of cytokines such as IFN-alpha may result in viral clearance during persistent infection and reverts this process.

Abstract
AIM To investigate the association between hepatitis C infection and type 2 diabetes mellitus. METHODS Observational studies assessing the relationship between hepatitis C infection and type 2 diabetes mellitus were identified via electronic and hand searches. Studies published between 1988 to March 2011 were screened, according to the inclusion criteria set for the present analysis. Authors performed separate analyses for the comparisons between hepatitis C virus (HCV) infected and not infected, and HCV infected and hepatitis B virus infected. The included studies were further subgrouped according to the study design. Heterogenity was assessed using I(2) statistics. The summary odds ratios with their corresponding 95% CIs were calculated based on a random-effects model. The included studies were subgrouped according to the study design. To assess any factor that could potentially affect the outcome, results were further stratified by age group (proportion of ≥ 40 years), gender (proportion of male gender), body mass index (BMI) (proportion of BMI ≥ 27), and family history of diabetes (i.e., self reported). For stability of results, a sensitivity analysis was conducted including only prospective studies. RESULTS Combining the electronic database and hand searches, a total of 35 observational studies (in 31 articles) were identified for the final analysis. Based on random-effects model, 17 studies (n = 286,084) compared hepatitis C-infected patients with those who were uninfected [summary odds ratio (OR): 1.68, 95% CI: 1.15-2.45]. Of these 17 studies, 7 were both a cross-sectional design (41.2%) and cohort design (41.2%), while 3 were case-control studies (17.6%). Nineteen studies (n = 51,156) compared hepatitis C-infected participants with hepatitis B-infected (summary OR: 1.92, 95% CI: 1.41-2.62). Of these 19 studies, 4 (21.1%), 6 (31.6%) and 9 (47.4%) were cross-sectional, cohort and case-control studies, respectively. A sensitivity analysis with 3 prospective studies indicated that hepatitis C-infected patients had a higher risk of developing type 2 diabetes compared with uninfected controls (summary odds ratio: 1.41, 95% CI: 1.17-1.7; I(2) = 0%). Among hepatitis C-infected patients, male patients (OR: 1.26, 95% CI: 1.03-1.54) with age over 40 years (summary OR: 7.39, 95% CI: 3.82-9.38) had an increased frequency of type 2 diabetes. Some caution must be taken in the interpretation of these results because there may be unmeasured confounding factors which may introduce bias. CONCLUSION The findings support the association between hepatitis C infection and type 2 diabetes mellitus. The direction of association remains to be determined, however. Prospective studies with adequate sample sizes are recommended.

Abstract
The objective of the present cross-sectional study was to assess the prevalence and the clinical and laboratory features of hepatitis C virus (HCV)-positive patients with type 2 diabetes mellitus (DM) attending either an outpatient clinic or hemodialysis units. Serologic-HCV testing was performed in 489 type 2 DM patients (303 outpatients and 186 on dialysis). A structured assessment of clinical, laboratory and DM-related complications was performed and the patients were then compared according to HCV infection status. Mean patient age was 60 years; HCV positivity (HCV+) was observed in 39 of 303 (12.9%) outpatients and in 34 of 186 (18.7%) dialysis patients. Among HCV+ patients, 32 were men (43.8%). HCV+ patients had higher serum levels of aspartate aminotransferase (0.90 ± 0.83 vs 0.35 ± 0.13 μKat/L), alanine aminotransferase (0.88 ± 0.93 vs 0.38 ± 0.19 μKat/L), gamma-glutamyl transferase (1.57 ± 2.52 vs 0.62 ± 0.87 μKat/L; P < 0.001), and serum iron (17.65 ± 6.68 vs 14.96 ± 4.72 μM; P = 0.011), and lower leukocyte and platelet counts (P = 0.010 and P < 0.001, respectively) than HCV-negative (HCV-) patients. HCV+ dialysis patients had higher diastolic blood pressure than HCV- patients (87.5 ± 6.7 vs 81.5 ± 6.0 mmHg; P = 0.005) and a lower prevalence of diabetic retinopathy (75 vs 92.7%; P = 0.007). In conclusion, our study showed that HCV is common among subjects with type 2 DM but is not associated with a higher prevalence of chronic diabetic complications.

Abstract
Important breakthroughs have been made in recent years into understanding the close interaction between hepatitis C virus (HCV) infection and glucose homeostasis. Both cross-sectional and longitudinal studies have demonstrated that infection with HCV is associated with an increased risk of developing insulin resistance and Type 2 diabetes. A direct effect of HCV on hepatocyte insulin signaling has been shown in experimental models. Some preliminary observations seem to suggest that indirect mechanisms involving extrahepatic organs might also play a role. The interaction between HCV and glucose metabolism has significant clinical consequences. Insulin resistance and Type 2 diabetes not only accelerate the histological and clinical progression of chronic hepatitis C, but also reduce the virological response to IFN-α-based therapy. Thus, understanding the mechanisms underlying HCV-associated glucose metabolism derangements is of paramount interest in order to improve the clinical management of chronic hepatitis C. This article will focus on the studies that consistently argue in favor of an interrelation between HCV and insulin resistance and will highlight the latest discoveries in this field.

Abstract
Hepatic steatosis is commonly seen in patients with chronic hepatitis C virus (HCV) infection, and the prevalence is much higher prevalence than in the general population or in patients with chronic hepatitis B. Hepatic steatosis in patients with chronic hepatitis C can be due to alcohol consumption and host metabolic factors such as high body mass index (BMI), obesity, hyperlipidemia, metabolic syndrome and diabetes mellitus in which insulin resistance plays an important role. However, in genotype 3 HCV infection, hepatic steatosis can result from direct viral cytopathic effect. Demographic and clinical characteristics associated with hepatic steatosis in patients with chronic hepatitis C including older age, higher BMI, more genotype 3 infection, and higher mean serum levels of triglyceride, alanine aminotransferase and γ-glutamyl transpeptidase. The clinical relevance of hepatic steatosis in patients with chronic hepatitis C includes a close correlation with hepatic fibrosis, and a poor response to combination peginterferon and ribavirin treatment. In addition, hepatic steatosis has been reported to associate with increased frequency of hepatocellular carcinoma in patients with chronic HCV infection. Whether life style modification such as weight reduction or adding an insulin resistance reducing agent such as metformin or thiazolidinediones combined with current standard peginterferon plus ribavirin treatment will benefit to the chronic hepatitis C patients with hepatic steatosis deserves further evaluation.

Abstract
PURPOSE To assess the prevalence and predictive factors of extrahepatic manifestation (EM) in patients with chronic hepatitis C (CHC) infection in Poland. MATERIAL AND METHODS 340 consecutive patients (mean age: 42 years) with untreated CHC were studied between 2000 and 2006. The HCV infection was defined by positive serology and serum HCV RNA. The inflammation grade and fibrosis stage were assessed according to Ishak. Demographic, laboratory and liver biopsy data were collected. The patients with liver cirrhosis, concomitant HBV or HIV infection, autoimmune liver diseases and alcohol abusers were excluded from the analysis. RESULTS 210 patients with CHC (61.7%) presented at least 1 extrahepatic manifestation, including mixed cryoglobulinemia (37.1%), thrombocytopenia (27.6%), thyroid autoimmunity (16.2%), dermatological disorders (4.1%) and type 2 diabetes (4.1%). Other EM such as the sicca syndrome, nephropathy, polyneuropathy and B-cell lymphoma were observed in single cases. In multivariate analysis lower platelet count was found as a predictive factor of EM in patients with CHC. CONCLUSIONS The majority of patients with CHC, living in Poland, have EM, of which cryoglobulinemia, thrombocytopenia, thyroid autoimmunity, dermatological disorders and type 2 diabetes are most common. Through the multivariate analysis the lower platelet predicts extrahepatic manifestations associated with chronic hepatitis C.

Abstract
BACKGROUND The prevalence of coronary artery disease (CAD) has been reported to be low in patients with liver cirrhosis. Previous studies have, however, included mostly patients with cirrhosis due to hepatitis C. We aimed to determine the prevalence and predictive factors of CAD in a cohort of consecutive patients with cirrhosis of various etiologies compared to the general population. METHODS A total of 127 patients with cirrhosis were evaluated for a history of CAD and cardiovascular risk factors. Arterial blood pressure, fasting plasma glucose, and serum cholesterol were measured. Nutritional status was assessed by anthropometry and estimation of recent weight change. A group of 203 subjects from the general population with similar age and gender distribution, as well as smoking habits as the cirrhotic patients, served as controls. RESULTS CAD was more common in cirrhotics compared to controls (20% vs. 12%, P = 0.001). Compared to controls, cirrhotics had lower mean arterial blood pressure and serum cholesterol and a higher prevalence of diabetes, but did not differ significantly in the prevalence of hypertension or family history for CAD. In regression analysis, CAD was independently related to diabetes (odds ratio [OR] 5.47, 95% confidence interval [CI] 2.44-12.28), but not to liver cirrhosis. In the cirrhosis group, only alcoholic cirrhosis (OR 9.50, 95% CI 1.08-83.4) and age (OR 1.23 per year, 95% CI 1.06-1.43) were independently related to CAD. CONCLUSIONS Liver cirrhosis, per se, does not seem to confer a protective effect against CAD. In cirrhotics, older age and alcoholic etiology were independently related to CAD.
