We aimed to evaluate the impact of non-alcoholic fatty liver disease (NAFLD) on viral kinetics and virologic response tenofovir entecavir treatment in patients with chronic hepatitis B virus (HBV) infection.This study was designed as a retrospective multicenter cohort study. The hepatosteatosis pre-treatment serum HBV DNA levels also either or at 6 12 months therapy investigated.A total 145 cases were involved [median age 40 (18-73) years, 90 (62%) males]. In multivariate analysis, it...

We aimed to determine whether mean platelet volume (MPV) is one of the variables that severity liver fibrosis and inflammation.Patients with chronic hepatitis B virus (HBV) infection were divided into two groups: patients scores 0-3 4-6 histologic activity index 0-9 10-18 (according Ishak Scoring System). The independent determining inflammation investigated.Two hundred thirty-eight included in this retrospective study. 29 (12.2%) higher than 3. determined score a high level serum γ-glutamyl...

The aim of the study was to determine association between platelet indices and disease severity, outcomes patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a secondary hospital.722 hospitalized who had positive rRT-PCR for SARS-CoV-2 and/or typical findings COVID-19 at chest computed tomography (CT) were enrolled this study. Initial count (PLT) indices, including mean volume (MPV), distribution width (PDW), plateletcrit (PCT), MPV/PCT, MPV/PLT, PDW/PLT, PDW/PCT on...

Background: Many noninvasive methods, including aspartate amino transaminase (AST)/alanine (ALT) ratio (AAR), AST-to-platelet index (APRI), Bonacini cirrhosis discriminant score (CDS), fibrosis-4 (FIB4) index, and age-platelet (API), have been described to determine the stage of hepatic fibrosis. However, these methods are developed for patients with chronic hepatitis C (CHC) produce conflicting results in prediction liver fibrosis B (CHB). Objectives: The aim this study was evaluate...

Background: Candida species have emerged as one of the most common causes bloodstream infections (BSIs). There are limited data on distribution spp. and susceptibility by year. Objectives: In this study, we analyzed changes in their antifungal profiles from blood cultures. Methods: Records January 2016 to December 2020 were obtained microbiology laboratory Istanbul. Antifungal tests performed using VITEK 2 compact system evaluated according EUCAST breakpoints. A total 241 unique candidemia...

Effects of whole cell type immunization on mice Ehrlich tumours were evaluated.After preliminary study, divided two major groups; 1 x 1000 and 100 live transferred groups, each into four subgroups (n: 10). Study groups immunized with lysates in 0, 3, 7, 14th days after 30 last immunization, cells transferred. Mice observed for six months evaluated total cancer free days.Out solid study group, all group mean tumour periods statistically longer than control groups. All survived significantly...
