Effect of a single, oral, high-dose vitamin D supplementation on endothelial function in patients with peripheral arterial disease: a randomised controlled pilot study

Apart from its role in bone metabolism, vitamin D may also influence cardiovascular disease. The objective of this study was: (1) to determine the effect of a single, oral, high-dose vitamin D supplementation on endothelial function and arterial stiffness in patients with peripheral arterial disease (PAD) and (2) to investigate the impact of this supplementation on coagulation and inflammation parameters

Prevalence of hepatitis C virus and GB-C virus infection among patients with B-cell non-Hodgkin's lymphoma: A case-control study of the International Extranodal Lymphoma Study Group

Background In regions with high prevalence of hepatitis C virus (HCV) thefrequency of this infection is higher in patients with B-cell non-Hodgkin lymphoma(B-NHL). Patients with HCV infection frequently show co-infectionswith GBV-C (previously named hepatitis G virus) and some studies have suggestedthe presence of higher incidence of GBV-C infection in patients withB-NHL.Aim Pilot study designed to test the feasibility of a future international prospectivestudy for the evaluation of the association between HCV and/orGBV-C and B-NHL in different geographic areas
