Sofosbuvir and simeprevir in hepatitis C genotype 1-patients with end-stage renal disease on haemodialysis or GFR <30 ml/min.

Background & Aims: Treating chronic hepatitis C (CHC) in patients with end-stage renal disease (ESRD) has suboptimal tolerability and cure rates. Safety and efficacy of sofosbuvir plus simeprevir regimen in CHC-infected patients with ESRD on haemodialysis (HD) or glomerular filtration rate (GFR) <30 ml/min is unknown. We evaluated the safety and efficacy of sofosbuvir and simeprevir in this special patient population.

Reduction in low-density lipoprotein cholesterol levels during statin therapy is associated with a reduced incidence of advanced colon polyps.

Background: Elevated serum cholesterol levels may stimulate proliferation in adenomatous polyps (AP). Our aim was to determine how a reduction of low-density lipoprotein (LDL) cholesterol levels in patients taking statins influences the incidence of APs.

Methods: We performed a retrospective study of patients taking statins who were found to have > or =1 APs on an index colonoscopy, and who also had a follow-up colonoscopy within 3 to 5 years.

Obesity is associated with an increased prevalence of advanced adenomatous colon polyps in a male veteran population.

Obesity has been associated with an increased risk for colonic adenomatous polyps (APs) and colorectal cancers, but the influence of obesity on the development of advanced APs is not clear. The purpose of this study is to determine the influence of obesity on the prevalence of advanced APs in a male veteran population. We performed a retrospective study of patients (n = 2,903) with histologically confirmed APs on an index colonoscopy.
