Circulating interferon- λ3 and post-vaccination antibodies against the surface antigen of hepatitis B virus in hemodialysis patients exposed to hepatitis E virus.

Circulating interferon-λ3 and post-vaccination antibodies against the surface antigen of hepatitis B virus in hemodialysis patients exposed to hepatitis E virus. Cytokine. 2019 Jul 03;123:154766 Authors: Grzegorzewska AE, Świderska MK, Winnicka H, Niepolski L, Bura M, Łagiedo-Żelazowska M, Jagodziński PP Abstract Responsiveness to the hepatitis B virus (HBV) vaccination in hemodialysis (HD) patients who had been exposed to the hepatitis E virus (HEV) and persistently generate antibodies against HEV remains unknown. Interferon (IFN)-λ3 positively correlates with the surface HBV antibodies (anti-HBs) in both healthy and HD subjects. We aimed to show whether HD patients differ in circulating IFN-λ3 and vaccine-induced anti-HBs titers concerning natural HEV immunization. HBV/HCV negative HD patients (31 HEV IgG positive, 45 HEV negative), HBV vaccinated and receiving booster doses as needed, had been tested for anti-HBs titers (CMIA) and IFN-λ3 concentrations (ELISA) in the blood collected before a dialysis session. There were no differences in circulating IFN-λ3 and anti-HBs titers between both groups. In responders to the HBV vaccine, there was a positive correlation between plasma IFN-λ3 levels and anti-HBs titers (r = 0.505, adjusted P = 0.01 in HEV exposed subjects; r = 0.523, adjusted P = 0.001 in controls). HEV past infection does not attenuate post-vaccination anti-HBs generation and does ...

Abstract Viral hepatitis B is a global public health problem affecting nearly two billion subjects; 3.3% of whom are from the WHO (World Health Organization) Eastern Mediterranean Region (EMRO). It induces both acute and chronic hepatic disorders with subsequent liver cirrhosis and hepatocellular carcinoma (HCC) in a considerable percentage of patients based on the age of exposure. In this review, hepatitis B virus (HBV) and HCC prevalence, distribution and prevalence of different genotypes, and male/female infection frequencies in relation to the vaccination status in the Mediterranean countries were reported. St...

Abstract Hepatitis B and hepatitis C (HCV) prevalence are higher in people on hemodialysis (HD) than the general population. Through implementation of prevention interventions including vaccines, serologic screening, and post-exposure management, transmissions linked to HD have decreased dramatically. In this manuscript, we review epidemiology of viral hepatitis, summarize current screening and vaccine recommendations, and appraise the available data about efforts to decrease incidence within HD facilities, including isolation of people with viral hepatitis within HD units. Also included is a discussion of the hig...

Conclusion: Prevalence of transfusion-transmissible viral infections was higher among hemodialysis patients, especially HCV infection which was an alarming situation and therefore strict adherence to infection control strategies, barrier precautions, and preventive measures, including routine hepatitis B vaccination and regular virological follow-up were recommended along with regular education and training programs of technical and nursing personnel's involved with dialysis patients.

This study aims to analyze the prevalence and to concentrate on the key risk factors that are responsible for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infection in patients on HD visiting two dialysis centers in the city of Quetta in southwestern Pakistan. The overall incidence of HBV was found to be 16.1%, the overall incidence of HCV was found to be 43.2%, and two patients (1.6%) were found to be positive for both HBV and HCV. HIV was not found among patients seen at both hospitals during the study period. The main risk factors for development of a viral infection were the ...

Publication date: May 2019Source: Advances in Chronic Kidney Disease, Volume 26, Issue 3Author(s): Vivek Soi, Sandeep SomanPatients with end-stage renal disease are at risk for contracting hepatitis B virus (HBV) because of their exposure to blood products and compromised immune status. Despite a decrease in the incidence of HBV infection, continued vigilance in the form of surveillance is imperative in preventing the spread of this robust DNA virus. Regular review of serologic markers with isolation and decontamination practices as appropriate are paramount to maintaining a safe environment for dialysis to occur. Vaccinat...

AbstractBackgroundIn hemodialysis patients Hepatitis B virus (HBV) infection is one of the problems. Because of HBV vaccine response is lower than in the general population, in this study it is aimed to determine the factors that may cause inadequate HBV vaccine response in hemodialysis patients.MethodsIn study, HBsAg, anti-HBs, anti-HBc IgG data belonging to 278 patients were obtained from file and computer records. It was seen that seronegative cases had been given recombinant HBV vaccine. Anti-HBs titers were monitored 1  month after vaccination was completed. According to this, the patients are divided into two gr...

Both hepatitis B and C viruses are acquired through hematogenous spread and can lead to horizontal transmission. Concurrent hepatic and renal injuries have ominous outcomes with significant morbidity. Hepatitis B incidence has decreased through practices including vaccination of nonimmune individuals and isolation of patients with the d...

Abstract Infection control measures have been responsible for a decline in the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in hemodialysis patients. In Brazil, these measures have been in place since 1996. The aim of this study was to evaluate the current HBV and HCV epidemiology among hemodialysis patients in the State of Tocantins comparing them with those found 14 years ago. There was a significant decline in hepatitis B surface antigen (HBsAg) and anti-HCV prevalence from 4% and 13% in 2001 to 0.8% and 2.8% in 2014-2015, respectively (p
