Resolution of non-alcoholic steatohepatitis by rosuvastatin monotherapy in patients with metabolic syndrome.

AIM: To investigate the effect of rosuvastatin monotherapy on non-alcoholic steatohepatitis (NASH). At present there is no effective treatment for non-alcoholic fatty liver disease or its advanced form NASH. METHODS: This prospective study included 20 biopsy proven patients with NASH, metabolic syndrome (MetS) and dyslipidaemia. Biochemical parameters of the blood of the patients and an ultrasonography of the liver were performed at baseline. Then patients received lifestyle advice and were treated for a 12 mo period with rosuvastatin (10 mg/d) monotherapy. Patients were re-evaluated during the study at 3 mo intervals, during which biochemical parameters of the blood were measured including liver enzymes. A repeat biopsy and ultrasonography of the liver were performed at the end of the study in all 20 patients. Changes in liver enzymes, fasting plasma glucose, serum creatinine, serum uric acid (SUA), high sensitivity C reactive protein (hsCRP) and lipid profile were assessed every 3 mo. The primary endpoint was the resolution of NASH and the secondary endpoints were the changes in liver enzyme and lipid values. RESULTS: The repeat liver biopsy and ultrasonography showed complete resolution of NASH in 19 patients, while the 20(th), which had no improvement but no deterioration either, developed arterial hypertension and substantial rise in triglyceride levels during the study, probably due to changes in lifestyle including alcohol abuse. Serum alanine transaminase, aspartate transaminase, and γ-glutamyl transpeptidase were normalised by the 3(rd) treatment month (ANOVA P < 0.001), while alkaline phosphatase activities by the 6(th) treatment month (ANOVA, P = 0.01). Fasting plasma glucose and glycated haemoglobin were significantly reduced (P < 0.001). Lipid values were normalised by the 3(rd) treatment month. No patient had MetS by the 9(th) treatment month. Body mass index and waist circumference remained unchanged during the study. Thus, changes in liver pathology and function should be attributed solely to rosuvastatin treatment. A limitation of the study is the absence of a control group. CONCLUSION: These findings suggest that rosuvastatin monotherapy could ameliorate biopsy proven NASH and resolve MetS within 12 mo. These effects and the reduction of fasting plasma glucose and SUA levels may reduce the risk of vascular and liver morbidity and mortality in NASH patients. These findings need confirmation in larger studies.

Effect of rosuvastatin on non-alcoholic steatohepatitis in patients with metabolic syndrome and hypercholesterolaemia: a preliminary report.

BACKGROUND: There is no widely accepted treatment for non-alcoholic fatty liver disease (NAFLD) or its advanced form, non-alcoholic steatohepatitis (NASH). METHODS: We administered rosuvastatin (10 mg/day) for 1 year in patients with metabolic syndrome (MetS), NASH on liver biopsy and dyslipidaemia (but without diabetes or arterial hypertension). Patients also received lifestyle advice. RESULTS: We report preliminary results for 6 patients. The second biopsy (at the end of the study) showed complete resolution of NASH in 5 patients, while the 6(th), which had no improvement, developed arterial hypertension and substantial rise in triglyceride levels during the study. We suspect alcohol abuse despite advice to abstain. Serum alanine transaminase (ALT) and aspartate transaminase (AST) activities were reduced by 76 and 61%, respectively (p < 0.001 for both), during treatment, while γ-glutamyl transpeptidase (γ-GT), and alkaline phosphatase (AP) showed smaller non significant reductions. Fasting plasma glucose and glycated haemoglobin (HbA1c) were significantly reduced (p<0.05). Lipid values were totally normalised and liver ultrasonography showed a complete resolution of NASH in 5 patients. Body mass index and waist circumference remained unchanged during the study. Thus, changes in liver pathology and function should be attributed to treatment with rosuvastatin. A substantial limitation of the study is the small number of patients. CONCLUSIONS: These preliminary findings suggest that rosuvastatin could ameliorate NASH within a year of treatment in MetS patients with dyslipidaemia.

Thyroid dysfunction and long-term outcome during and after interferon-alpha therapy in patients with chronic hepatitis C.

INTRODUCTION: Thyroid dysfunction (TD) is a well-established adverse effect in chronic hepatitis C virus (HCV)-infected patients, treated with interferon-alpha (IFN-α), with or without ribavirin. However, the long-term outcome is not well-studied. The purpose of this study was to estimate the prevalence and long-term outcome of TD after HCV-therapy. MATERIALS AND METHODS: Retrospective analysis of 109 HCV-treated patients (for 6 to 12 months, according to HCV genotype), for the period 1996 to 2008. Thyroid function tests were performed every 3 months during therapy and after discontinuation (3 months to 12 years). Routine laboratory tests and virological assessment were performed according to generally accepted practice. RESULTS: TD was observed in 26 patients (23.85%). The positive and negative predictive value for thyroid autoantibodies (ATA) was 80% and 72.7%, respectively. Relative risk for those with positive ATA was 2.9 (95% CI: 1.6 to 5.3, P = 0.014). The median duration of TD was 12.0 months (min: 3; max: 132). The median follow-up period for the patients with TD was 25.5 months (min: 12; max: 144). Finally, 15 patients developed permanent TD (57.69%), compared to 11 with temporary TD (42.31%). Sex is a risk factor for TD, as there were more females than males affected (P = 0.011). Genotype, viral load, time of HCV-exposure prior to therapy, and virological response did not differ between patients with and without TD. CONCLUSION: TD among HCV-treated patients was more frequent than usually reported, with >50% developing permanent TD. ATA status may play a role in estimating the risk of subsequent TD. Women appear to be more vulnerable to TD than men.

Safety and efficacy of long-term statin treatment for cardiovascular events in patients with coronary heart disease and abnormal liver tests in the Greek Atorvastatin and Coronary Heart Disease Evaluation (GREACE) Study: a post-hoc analysis.

BACKGROUND: Long-term statin treatment reduces the frequency of cardiovascular events, but safety and efficacy in patients with abnormal liver tests is unclear. We assessed whether statin therapy is safe and effective for these patients through post-hoc analysis of the Greek Atorvastatin and Coronary Heart Disease Evaluation (GREACE) study population. METHODS: GREACE was a prospective, intention-to-treat study that randomly assigned by a computer-generated randomisation list 1600 patients with coronary heart disease (aged <75 years, with serum concentrations of LDL cholesterol >2·6 mmol/L and triglycerides <4·5 mmol/L) at the Hippokration University Hospital, Thessaloniki, Greece to receive statin or usual care, which could include statins. The primary outcome of our post-hoc analysis was risk reduction for first recurrent cardiovascular event in patients treated with a statin who had moderately abnormal liver tests (defined as serum alanine aminotransferase or aspartate aminotransferase concentrations of less than three times the upper limit of normal) compared with patients with abnormal liver tests who did not receive a statin. This risk reduction was compared with that for patients treated (or not) with statin and normal liver tests. FINDINGS: Of 437 patients with moderately abnormal liver tests at baseline, which were possibly associated with non-alcoholic fatty liver disease, 227 who were treated with a statin (mainly atorvastatin 24 mg per day) had substantial improvement in liver tests (p<0·0001) whereas 210 not treated with a statin had further increases of liver enzyme concentrations. Cardiovascular events occurred in 22 (10%) of 227 patients with abnormal liver tests who received statin (3·2 events per 100 patient-years) and 63 (30%) of 210 patients with abnormal liver tests who did not receive statin (10·0 events per 100 patient-years; 68% relative risk reduction, p<0·0001). This cardiovascular disease benefit was greater (p=0·0074) than it was in patients with normal liver tests (90 [14%] events in 653 patients receiving a statin [4·6 per 100 patient-years] vs 117 [23%] in 510 patients not receiving a statin [7·6 per 100 patient-years]; 39% relative risk reduction, p<0·0001). Seven (<1%) of 880 participants who received a statin discontinued statin treatment because of liver-related adverse effects (transaminase concentrations more than three-times the upper limit of normal). INTERPRETATION: Statin treatment is safe and can improve liver tests and reduce cardiovascular morbidity in patients with mild-to-moderately abnormal liver tests that are potentially attributable to non-alcoholic fatty liver disease. FUNDING: None.

Comparison of four definitions of the metabolic syndrome in a Greek (Mediterranean) population.

BACKGROUND: There is a need to evaluate the prevalence of metabolic syndrome (MetS) diagnosed by the new Joint Interim Societies (JIS) MetS definition. The JIS definition was compared with three previous definitions to assess their ability to predict cardiovascular disease (CVD) risk. METHODS: A cross-sectional analysis of a representative sample of Greek adults (n = 9669) was performed to estimate the prevalence of MetS and CVD using the JIS vs. the three older definitions of MetS: the National Cholesterol Education Program-Adult Treatment Panel-III (NCEP-ATP-III), the International Diabetes Federation (IDF) and the American Heart Association/National Heart Lung and Blood Institute (AHA/NHLBI) definitions. RESULTS: The age-adjusted MetS prevalence was 45.7%, 43.4%, 24.5% and 26.3% (ANOVA p < 0.001) with the JIS, IDF, NCEP and AHA/NHLBI definitions. The prevalence of CVD was 11.4% in the whole study population and 17.6%, 18.3%, 23.3%, 22.6% and in subjects with MetS according to the JIS, IDF, NCEP and AHA/NHLBI definitions (ANOVA p < 0.001). The prevalence of CVD was only 10.4% (i.e., lower than in the whole study population) in subjects with MetS according to the JIS but not according to the NCEP-ATP-III and AHA/NHLBI definitions (p < 0.001 vs. subjects with MetS as defined by NCEP-ATP-III or AHA/NHLBI). CONCLUSIONS: When diagnosed according to the new JIS definition, the prevalence of MetS was high in a Greek Mediterranean cohort (nearly half of the adult population). The NCEP-ATP-III and AHA/NHLBI definitions were more predictive of CVD risk than the new JIS definition. These findings, though limited by the cross sectional analysis, may have implications regarding the choice of the definition to diagnose MetS.

Late onset ulcerative colitis complicating a patient with Budd-Chiari syndrome: a case report and review of the literature.

We report a case of a 33-year-old female patient with Budd-Chiari syndrome because of polycythemia vera. A transjugular intrahepatic portal-systemic shunt was performed because of refractory ascites 7 months after diagnosis. She had a stable hepatic function receiving anticoagulants until 3 years later when she presented with bloody diarrheas, liver function deterioration with prolonged prothrombin time and hypoalbuminemia, encephalopathy, and ascites. Colonoscopy revealed ulcerative pancolitis and the patient was treated with corticosteroids and antibiotics. Hepatic function was stabilized in parallel to controlling ulcerative colitis and the patient is in good health until now receiving maintenance therapy for ulcerative colitis and anticoagulants for Budd-Chiari syndrome.
