Non-alcoholic steatohepatitis (NASH) is emerging as an important cause of cryptogenic cirrhosis. Obesity, diabetes mellitus and hyperlipidaemia are important risk factors for NASH. The presence of these risk factors in patients with cryptogenic cirrhosis may suggest NASH as an aetiology of cirrhosis in them. Twenty-five patients of cryptogenic cirrhosis were compared with 18 patients of hepatitis B virus and hepatitis C virus related cirrhosis and primary biliary cirrhosis for the presence of obesity, diabetes mellitus and hyperlipidaemia. Patients with cryptogenic cirrhosis were found to have a significantly higher body - mass index increased prevalence of diabetes mellitus and lower high-density lipoprotein compared to the controls. Increased body weight and diabetes mellitus may play a role in the causation of cirrhosis in patients with cryptogenic cirrhosis.

The study examined health conditions among an aging cohort of male narcotics addicts. This prospective cohort study (1964-1998) included interviews and medical testing for 108 surviving subjects who had been admitted to the California Civil Addict Program during the years 1962 through 1964. Medical testing results were: 51.9% had high blood pressure, 22.4% showed hyperlipidemia, 13.3% had elevated levels of blood glucose, 33.6% had abnormal pulmonary function, half of the sample had abnormal liver function, and 94.2% tested positive for hepatitis C, 85.6% for hepatitis B, 3.8% for syphilis, and 27.3% for TB. The study empirically demonstrated poor health conditions and high morbidity among surviving narcotics addicts.

Hepatic steatosis is the hallmark of nonalcoholic fatty liver disease (NAFLD), which is the consequence of multiple metabolic derangements among which insulin resistance plays a pivotal role. Steatosis is, also, a feature of hepatitis C virus (HCV) infection. However, in chronic hepatitis C, the prevalence of steatosis is 2.5-fold more elevated than that expected by a chance concurrence with NAFLD, suggesting that HCV may be implied in the development of steatosis. As observed in NAFLD, in patients infected with HCV genotype 1 steatosis is associated with an increased body mass index. On the other hand, in patients infected with genotype 3 the extent of steatosis strictly correlates with the viral load indicating that steatosis is mainly "virus-related". Regardless of the "metabolic" or "viral" etiology, hepatic steatosis in HCV contributes to the progression of liver fibrosis, to the development of hepatocellular carcinoma and to an impaired response to interferon treatment. Features such as obesity, insulin resistance and type 2 diabetes mellitus are shared by NAFLD and HCV-associated steatosis. In addition, HCV infection, directly or through steatosis, favors the development of type 2 diabetes mellitus. Hyperlipidemia is an independent predictor of the development of NAFLD, but not of HCV-associated steatosis. Arterial hypertension is common in nonalcoholic steatohepatitis patients, and HCV infection has recently been acknowledged as an independent risk factor for atherosclerosis. The role of iron in the progression of both NAFLD and HCV-associated steatosis remains controversial while lipoperoxidation and oxidative stress are pathogenic mechanisms shared by both. Some metabolic risk factors may be shared by both HCV-associated steatosis and NAFLD although the disease progression and pathophysiological background may be different. Preliminary data suggest that the therapeutic options for NAFLD may also be useful to improve HCV-associated steatosis.

The objective of this study was to find predictive factors of lopinavir/ritonavir (LPV/r) discontinuation for drug-related toxicities in highly pre-treated human immunodeficiency virus (HIV)-infected subjects. The study was an observational study of HIV patients starting LPV/r with HIV RNA > 3log10 copies/mL and a follow-up > or = 6 months. Parameters studied were HIV RNA, CD4+ cell counts, metabolic parameters and drug-related adverse events. Acquired immune deficiency syndrome (AIDS) events and deaths were recorded. The Kaplan-Meier (KM) model was used to estimate time-dependent probability, and the multivariable Cox model to identify predictors of LPV/r discontinuation for adverse events. The study evaluated 416 HIV-infected patients. Seventy-seven patients (18.5%) discontinued LPV/r for toxicities. Adverse events leading to LPV/r discontinuation were gastrointestinal symptoms in 40 cases, hyperlipidaemia in 27 and increase of aspartate aminotransferase (AST)/alanine aminotransferase (ALT) in 10 patients. Nineteen patients (4.6%) developed an AIDS event during observation and 15 (3.6%) died. The KM probability of LPV/r discontinuation for toxicities was 5.3% (range 3.1-7.5%) at month 12 and 15.7% (range 12.1-19.3%) at month 24. Subjects with hepatitis C virus (HCV)-HIV co-infection (odds ratio (OR) 7.40; 95% confidence interval (CI) 3.73-14.66 versus HCV-negative; P = 0.001) and receiving LPV/r plus nucleoside reverse transcriptase inhibitors (NRTIs) and protease inhibitor (PI)/non-nucleoside reverse transcriptase inhibitor (NNRTI) (OR 1.74; 95% CI 1.04-2.91 versus LPV/r plus only NRTIs; P = 0.04) showed a higher risk of LPV/r discontinuation by a Cox analysis, whereas non-intravenous drug abusers (IVDUs) (OR 0.40; 95% CI 0.24-0.67 versus IVDUs; P = 0.001) had a lower risk. The rate of discontinuation for toxicity decreased by 17% for each additional month of LPV/r exposure (OR 0.83; 95% CI 0.80-0.86 for each additional month; P < 0.001). LPV/r was substantially well tolerated. Diarrhoea was the most frequent adverse event leading to discontinuation. HCV-HIV co-infected patients and patients with a short exposure to LPV/r have a higher risk of discontinuing LPV/r and should be strictly monitored.

We reviewed the current literature on medical comorbidity burden in bipolar disorder. Overall, current studies suggest that numerous medical conditions may occur disproportionately within bipolar disorder patient populations, including hypertension, hyperlipidemia, and hepatitis C infection. In addition, the determinants of increased burden of medical comorbidity in patients with bipolar disorder include metabolic-related factors, health care access barriers, and patient behavioral and treatment factors. Overall, interventions specifically designed to reduce the burden of medical comorbidity in bipolar disorder are needed, especially those that emphasize changes at the health system level to facilitate coordination of medical and psychiatric care.

Hepatic steatosis is a common histological feature of chronic hepatitis C. Various factors are associated with hepatic steatosis, including obesity, high alcohol consumption, diabetes type II, and hyperlipidaemia. These factors may contribute to steatosis in patients with chronic hepatitis C. In humans, hepatitis C virus (HCV) genotype 3 is more commonly associated with steatosis. In vitro studies and the transgenic mouse model have suggested that the HCV core protein (genotype 1) can induce lipid accumulation within hepatocytes. However, what is the relevance of steatosis in chronic hepatitis C? It seems that in certain populations, steatosis may be associated with fibrosis progression and this may be genotype specific. The mechanisms underlying this association are unknown; neither is it clear whether this holds true for all patients or only a subgroup. Indeed, after antiviral treatment, virus related steatosis disappears whereas the host associated steatosis remains unaffected. This review describes and discusses the basic and clinical aspects of the relationship between steatosis and progression of fibrosis, and response to treatment in patients with chronic hepatitis C.

There are two discrete forms of steatosis that may be found in patients infected with hepatitis C virus (HCV). Metabolic steatosis can coexist with HCV, regardless of genotype, in patients with risk factors such as obesity, hyperlipidemia, and insulin resistance. The second form of hepatic steatosis in HCV patients is a result of the direct cytopathic effect of genotype 3 viral infections. There have been proposed mechanisms for this process but it remains elusive. Both categories of steatosis tend to hasten the progression of liver fibrosis and therefore prompt recognition and management should be initiated in patients with HCV and steatosis. The authors review the current understanding of the relationship between hepatitis C infection and hepatic steatosis and discuss future research directions.

An association of hepatitis C virus (HCV) with low-density lipoproteins (LDL) in serum of patients with chronic hepatitis C (CHC) has been suggested. We conducted a prospective study in CHC patients complicated with hyperlipidaemia, to examine whether bezafibrate, which is commonly used for treatment of hyperlipidaemia, reduces serum HCV-RNA titre and improves liver dysfunction. Fifteen patients received daily oral bezafibrate treatment (400 mg/day) for 8 weeks, and its effects on serum lipids, transaminases, HCV-RNA titres, and HCV-RNA titres bound to LDL were evaluated. Fifteen untreated patients with CHC and hyperlipidaemia were used as controls. The mean serum alanine aminotransferase levels and HCV-RNA titres significantly decreased at the end of bezafibrate therapy in the treated group (105 +/- 34 to 80 +/- 32 IU/L, P = 0.02 and 2.23 +/- 2.71 to 1.78 +/- 2.38 x 10(7) copies/mL, P < 0.01 respectively), but no changes were observed in the control group. Serum HCV-RNA titres bound to LDL, as quantified by immunoprecipitation using anti-LDL antibody, also decreased in all 15 treated patients [5.55 +/- 6.59 to 1.07 +/- 1.58 x 10(6) copies/ml, P < 0.01 (mean reduction rate was -78.5 +/- 17.0%)]. Sucrose density-gradient ultracentrifugation study revealed that HCV-RNA-decreased density fractions after the bezafibrate were identical to LDL-density fractions (1.015-1.062 g/mL). Eight CHC patients were treated with bezafibrate, interferon, and ribavirin triple therapy for 32 weeks, and four patients achieved sustained virological response to therapy. This pilot study provides further evidence of an association between HCV and LDL in serum and suggests the potential usefulness of bezafibrate as an anti-HCV reagent for the treatment of CHC patients.

Corticosteroids have always played a valuable role in transplantation. Unfortunately, they are subject to a wide range of side effects, such as hyperlipidemia, hypertension, diabetes mellitus, osteoporosis, growth retardation and Cushingoid appearance. Steroids may also exacerbate problems that existed before surgery, including malignancy, hepatitis B and hepatitis C. New, powerful immunosuppressants have allowed steroid use to be reduced or avoided altogether, but use of these regimens is not simple and may be associated with late acute rejection and recurrence of autoimmune disease. The present review examines the rationale for steroid avoidance in liver transplantation and assesses the new regimens that are currently being developed.

The LIS2T study was an open-label, multicenter study in which recipients of a primary liver transplant were randomized to cyclosporine microemulsion (CsA-ME) (Neoral) (n = 250) (monitoring of blood concentration at 2 hours postdose) C2 or tacrolimus (n = 245) (monitoring of trough drug blood level [predose]) C0 to compare efficacy and safety at 3 and 6 months and to evaluate patient status at 12 months. All patients received steroids with or without azathioprine. At 12 months, 85% of CsA-ME patients and 86% of tacrolimus patients survived with a functioning graft (P not significant). Efficacy was similar in deceased- and living-donor recipients. Significantly fewer hepatitis C-positive patients died or lost their graft by 12 months with CsA-ME (5/88, 6%) than with tacrolimus (14/85, 16%) (P < 0.03). Recurrence of hepatitis C virus in liver grafts was similar in each group. Based on biopsies driven by clinical events, the mean time to histological diagnosis of hepatitis C virus recurrence was significantly longer with CsA-ME (100 +/- 50 days) than with tacrolimus (70 +/- 40 days) (P < 0.05). Median serum creatinine at 12 months was 106 mumol/L with CsA-ME and with tacrolimus. More patients who were nondiabetic at baseline received antihyperglycemic therapy in the tacrolimus group at 12 months (13% vs. 5%, P < 0.01). Of patients who were diabetic at baseline, more tacrolimus-treated individuals required anti-diabetic treatment at 12 months (70% vs. 49%, P = 0.02). Treatment for de novo or preexisting hypertension or hyperlipidemia was similar in both groups. In conclusion, the efficacy of CsA-ME monitored by blood concentration at 2 hours postdose and tacrolimus in liver transplant patients is equivalent to 12 months, and renal function is similar. More patients required antidiabetic therapy with tacrolimus regardless of diabetic status at baseline.
