Hepatitis C Virus Core Antigen (HCVAg): an affordable assay to monitor the efficacy of treatment in DAAs era.

Hepatitis C virus (HCV) Core Antigen (HCVAg) and HCV-RNA were tested in 962 plasma/serum samples from 180 patients during Direct Antiviral Agents (DAAs) treatment and at follow-up. One hundred and eighty individuals were included: 71% carried advanced fibrosis and 43% were treatment-experienced. A Sustained Virological Response (SVR) was achieved in 166/180 (92%) individuals: 96/102 (94.

Syphilis in a high-density urban area in the North of Italy.

Although far less common now than in the past, syphilis continues to pose a danger to public health and should not be overlooked. In this study, we evaluated the presence and characteristics of syphilis in a group of patients attending an STI Clinic in the North of Italy. A retrospective study was carried out, analysing the data from the 5609 subjects who attended the STI Clinic of St.

The Effectiveness of Physical Exercise on Bone Density in Osteoporotic Patients.

Physical exercise is considered an effective means to stimulate bone osteogenesis in osteoporotic patients. The authors reviewed the current literature to define the most appropriate features of exercise for increasing bone density in osteoporotic patients. Two types emerged: (1) , i.

Serum hepatitis B core-related antigen is an effective tool to categorize patients with HBeAg-negative chronic hepatitis B.

The discrimination between active chronic hepatitis B (CHB) and the clinically quiescent infection (CIB) is not always easy, as a significant portion of patients falls in a "grey" zone. Hepatitis B core-related antigen (HBcrAg) is a now quantifiable serological marker with potential applications in diagnosis and therapy monitoring. The aim of the present study was to evaluate the HBcrAg serum levels in HBeAg-negative HBV infection, and its ability in identifying the clinical profile, in comparison with HBsAg serum levels.

Monitoring the treatment of hepatitis C with directly acting antivirals by serological and molecular methods.

Aim: To evaluate the potential value of using a serological assay to quantitate the hepatitis C virus core antigen (HCV-Ag) when monitoring patients with chronic hepatitis C being treated with direct-acting antivirals (DAAs).

Methods: Ninety-six patients treated with DAAs, either alone (91) or in combination with PEG interferon (5), were tested for HCV-RNA and for HCV-Ag at baseline and at weeks 2, 4, 8 and 12 during treatment and 12 weeks after completion. The concordance and correlation between the viral parameters as well as the respective kinetics during and after treatment were evaluated.
