BACKGROUND/AIMS: The distribution of blood lipids, glucose and their determinants in thalassemic patients with chronic hepatitis C virus (HCV) infection has rarely been investigated. Thus, we aimed to investigate the relationship between both liver histologic findings and viral markers and serum lipids in thalassemic patients chronically infected with HCV. METHODS: We enrolled 280 polytransfused thalassemic patients with chronic hepatitis C. HCV viral load was determined using the Amplicor test. Genotyping was performed using genotype specific primers. Fasting serum lipid, glucose, ferritin and liver function enzyme concentrations were measured. A modified Knodell scoring system was used to stage liver fibrosis and to grade necroinflammatory activity. Perls' staining was used to assess hepatic siderosis. RESULTS: Just one subject had total cholesterol >200 mg/dL, and 7% had triglycerides >150 mg/dL. The mean high-density lipoprotein cholesterol (HDL-C) and glucose levels were 37 and 104 (97-111) mg/dL, respectively. Viral markers, liver histological findings and aminotransferase activity were not associated with serum lipid levels. Serum triglycerides, total cholesterol and ferritin were independent risk factors for impaired glucose tolerance or diabetes in these patients. CONCLUSIONS: The majority of the patients had blood lipid levels (with the exception of HDL) within the defined normal range; viral and liver histological factors do not appear to play a significant role in changing the levels of serum lipids or glucose in these patients.

OBJECTIVETo explore demographic and metabolic factors associated with increased alanine aminotransferase (ALT) activity in non-diabetic non-alcoholic fatty liver disease (NAFLD) patients.

METHODSOverall 372 patients who consecutively attended to Gastroenterology Clinic of Baqiyatallah University of Medical Sciences, Tehran, Iran awere diagnosed as NAFLD entered into analysis. Exclusion criteria were having diabetes mellitus and fasting blood glucose over 126 mg/dL, active hepatitis B virus infection, having hepatitis C virus positive serology, and to be under corticosteroid therapy. ALT levels were considered pathologically high when it was over 30 IU/L for men and over 19 IU/L for women.

RESULTSBivariate analyses using t test and chi-square test showed that patients with pathologically augmented ALT levels had significantly higher NAFLD grades in their ultrasonographic evaluations (P=0.003). Moreover, these patients represented significantly higher homeostatic model assessment levels (P=0.003), levels of serum insulin (P=0.002), fasting blood glucose (P<0.001), and uric acid (P=0.02). The prevalence of insulin resistance was also higher in patients with increased serum ALT concentrations. Multifactorial logistic regression models showed that ultrasonographic grading of NAFLD (P=0.027) and insulin resistance (P=0.013) were the only variables significantly associated with abnormal ALT levels.

CONCLUSIONSThis study shows that the associations of increased ALT serum levels in NAFLD patients are different from what are supposed before. By excluding diabetic patients from our population, we find that increased ALT levels are not associated with dyslipidemias but are independently associated with insulin resistance and NAFLD grading on ultrasonographic evaluations. Further studies are needed to confirm our results.
