Retinol-binding protein 4 (RBP4) : a new marker of G1 HCV-induced steatosis

INSULIN RESISTANCE AND SEVERITY OF FIBROSIS IN HCV GENOTYPE 1 CHRONIC HEPATITIS.

Effectiveness of screening for known mutations in Sicilian patients with "probable" familial hypercholesterolemia.

Background and Aim: More than 750 mutations in the low-density lipoprotein (LDL) receptor gene are currently known to cause familial hypercholesterolemia (FH), but the array of mutations varies considerably in different populations. The definition of essentially all the LDL receptor gene mutations in a population is therefore a prerequisite for the implementation of nation-wide genetic testing for FH. Methods and Results: In this study, a screening strategy based on PCR-enzymatic digestion and PCR-allele specific hybridisation procedures was used to evaluate the frequency distributions of 11 known mutations in a cohort of 214 unrelated subjects meeting the diagnostic criteria of "probable" …

Insulin resistance and diabetes increase fibrosis in the liver of patients with genotype 1 HCV infection.

OBJECTIVES: Metabolic factors may affect the course of chronic hepatitis C (CHC). Insulin resistance (IR) determines steatosis, but its direct role in affecting progression of hepatic fibrosis is less clear. We aimed to assess whether increasing degrees of IR, up to overt diabetes, are linked to steatosis and higher stages of fibrosis in patients with CHC resulting from genotype 1 HCV (G1-HCV). METHODS: Two hundred one consecutive patients with G1-HCV infection were evaluated by liver biopsy and anthropometric and metabolic measurements, including IR, by the homeostasis model assessment (HOMA). Nondiabetic patients were defined as insulin resistant if HOMA-IR was >2.7. All biopsies were …
