Article Synopsis
  • - The study analyzed data from a randomized trial in Türkiye involving 1,266 volunteers aged 18-55 to assess how previous COVID-19 infections affected adverse events after receiving the TURKOVAC vaccine compared to CoronaVac.
  • - Among participants, 27.7% had a history of COVID-19, with local and systemic adverse events (AEs) occurring in 37.3% and 39% of individuals, respectively, and slightly higher rates were noted shortly after vaccination.
  • - Following the second dose, 1,203 participants were evaluated, showing similar rates of local and systemic AEs for those with and without prior COVID-19 infection, with both TURKOVAC and CoronaVac exhibiting comparable

We present the interim results of the efficacy, immunogenicity, and safety of the two-dose schedules of TURKOVAC versus CoronaVac. This was a randomized, observer-blinded, non-inferiority trial (NCT04942405). Volunteers were 18-55 years old and randomized at a 1:1 ratio to receive either TURKOVAC or CoronaVac at Day 0 and Day 28, both of which are 3 μg/0.

Article Synopsis
  • This study investigates how the Charlson Comorbidity Index can predict poor clinical outcomes in COVID-19 patients, considering factors like age and existing health conditions.
  • A total of 213 patients were analyzed, revealing a comorbidity rate of 50.7%, with hypertension and diabetes being the most common conditions; older age significantly increased the risk for severe outcomes.
  • The findings suggest that using the Charlson Comorbidity Index can help identify patients at higher risk for complications and mortality from COVID-19, aiding in better management and treatment strategies.

Background And Objective: Integrase strand transfer inhibitors (INSTIs) are currently the standard of practice for first-line HIV therapy for most patients. We evaluated the mutations associated with INSTI resistance in naive HIV-1 infected patients and treated them with antiretrovirals (ART).

Methods: The study, conducted in the 2018 - 2020 period, included 50 ART-naïve patients, 69 INSTI free ART-experienced patients, and 82 INSTI-experienced patients.

Background: CoronaVac, an inactivated whole-virion SARS-CoV-2 vaccine, has been shown to be well tolerated with a good safety profile in individuals aged 18 years and older in phase 1/2 trials, and provided a good humoral response against SARS-CoV-2. We present the interim efficacy and safety results of a phase 3 clinical trial of CoronaVac in Turkey.

Methods: This was a double-blind, randomised, placebo-controlled phase 3 trial.

Objective: Occult hepatitis B infection (OHBI) appears to have a higher prevalence in populations at high risk for hepatitis B virus (HBV) infection with concomitant liver disease. The aim was to assess the prevalence of OHBI in a sample of human immunodeficiency virus -1 positive and HBV surface antigen-negative (HIV-1+/HBsAg-) Turkish patients.

Methods: Ten centres in Turkey were included in the study.

Background: In this study, we aimed to investigate the efficacy and safety of sofosbuvir-based therapies in the treatment of chronic hepatitis C in real-world clinical practice.

Methods: Data from patients with chronic hepatitis C treated with SOF/LDV ± RBV or SOF/RBV in 31 centers across Turkey between April 1, 2017, and August 31, 2018, were recorded in a nationwide database among infectious disease specialists. Demographics, clinical, and virological outcomes were analyzed.

Aim: In the diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), reverse transcriptase-PCR (RT-PCR) technique is often used. We evaluated the compatibility of SARS-CoV-2 RT-PCR kits containing different gene targets during the pandemic.

Materials & Methods: Samples were tested by Bio-Speddy ( gene) and Diagnovital ( genes).

Objectives: Chronic hepatitis C (CHC) is now a more curable disease with new direct acting antivirals (DAA). Although high sustained virologic response rates, failures still occur in DAA regimens. Our objective in this study was to characterize the real-life presence of clinically relevant resistance - associated substitutions (RASs) in the HCV NS5A gene in CHC patients whose DAA regimen has failed.

Objective: The recent development of direct-acting antiviral agents (DAAs) has dramatically changed the treatment of chronic hepatitis C, and interferon-based regimes have become a poor treatment choice in clinical practice. Today DAAs offer shorter, well-tolerated, highly effective curative therapies. This study aimed to evaluate the effectiveness and safety of DAAs in patients with end-stage renal disease and HCV genotype 1 infection in real clinical practice.

The aims of the present study were to evaluate the efficacy and tolerability of ledipasvir/sofosbuvir (LDV/SOF) with or without ribavirin in the treatment of chronic hepatitis C (CHC) in patients with advanced liver disease and to analyse whether the use of LDV/SOF treatment is associated with a new occurrence of hepatocellular carcinoma (HCC) during and after LDV/SOF treatment. The Turkish Early Access Program provided LDV/SOF treatment to a total of 200 eligible CHC patients with advanced liver disease. The median follow-up period was 22 months.

Background/aims: The hepatitis C virus (HCV) infection is important cause of chronic hepatitis. Liver biopsy is considered the gold standard for assessment of fibrosis but this procedure is an invasive procedure. We aimed to evaluate the diagnostic efficiency of non-invasive serum biomarkers, separately and in combinations, on liver fibrosis in treatment-naive chronic hepatitis C (CHC) patients.

Background: Drug resistance development is an expected problem during treatment with protease inhibitors (PIs), this is largely due to the fact that Pls are low-genetic barrier drugs. Resistance-associated variants (RAVs) however may also occur naturally, and prior to treatment with Pls, the clinical impact of this basal resistance remains unknown. In Turkey, there is yet to be an investigation into the hepatitis C (HCV) drug associated resistance to oral antivirals.

Background: Before the introduction of direct-acting antivirals in the treatment of chronic hepatitis C patients, the combination of peginterferon alpha and ribavirin was the standard therapy. Observational studies that investigated sustained virological response (SVR) rates by these drugs yielded different outcomes.

Aims: The goal of the study was to demonstrate real life data concerning SVR rate achieved by peginterferon alpha plus ribavirin in patients who were treatment-naïve.

Background: The use of pegylated interferon alpha and ribavirin (PegIFN/RBV) for the retreatment of chronic hepatitis C virus (HCV) infection without a sustained virological response (SVR) prior to PegIFN/RBV treatment has resulted in low success rates.

Aims: To investigate the efficacy and safety of telaprevir (TVR) in combination with PegIFN/RBV in patients infected with HCV genotypes 1 and 4 who were previously treated with PegIFN/RBV and failed to achieve SVR.

Study Design: Multi-center, retrospective, cross-sectional study.

Introduction: Although pegylated interferons (pegIFNs) alpha-2a and alpha-2b have been used in chronic hepatitis B (CHB) treatment for many years, there are few studies concerning predictors of sustained virologic response (SVR) to pegIFN therapy. In this study, we aimed to investigate the predictors of response to pegIFN treatment in cases with HBeAg-negative CHB infection.

Methodology: Seventeen tertiary care hospitals in Turkey were included in this study.
