Hepatitis C virus core antigen assay: can we think beyond convention in resource limited settings?
Hepatitis C virus infects over 15 million patients from India and 2.86 million from Brazil. Detection of anti-hepatitis C virus antibodies has limited sensitivity during acute phase: the pre-seroconversion window period. Hepatitis C virus-RNA detection techniques are used to overcome this shortfall, but are costly and unavailable widely in developing countries. Estimation of hepatitis C virus c...
متن کاملEvaluation of in-house polymerase chain reaction assay sensitivity, can it be utilized in limited-resources settings?
Background :Polymerase chain reaction (PCR) assay has widely used for the detection of tuberculosis (TB). This study tried to compare in-house PCR with some well-known commercial PCR kits for detection of TB agent. Methods : Clinical samples obtained from 620 TB suspected patients were analyzed for the diagnosis of Mycobacterium tuberculosis complex (MTC) by in-house PCR. All samples were o...
متن کاملExpression of Hepatitis B Virus Core Antigen in Native and Fusion Forms in E. coli
DNA coding for the core antigen from hepatitis B Virus (HBcAg) was amplified, cloned and propagated in E. coli. The core protein was expressed in E. coli and the product was readily detected by Western blot. This protein can be used as a diagnostic material in serum screening tests. To increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...
متن کاملDevelopment and evaluation of an in-house ELISA to detect hepatitis B virus surface antigen in resource-limited settings.
Hepatitis B virus (HBV) infection is of global public health concern. Among various serological tests used for the diagnosis and screening of HBV infection, the enzyme-linked immunosorbent assay (ELISA) to detect hepatitis B surface antigen (HbsAg) is most widely used. The present study was designed to develop and standardize a cost effective in-house ELISA for the detection of HbsAg and compar...
متن کاملClinical utility of hepatitis C virus core antigen quantification in patients with chronic hepatitis C.
BACKGROUND Hepatitis C virus (HCV) core antigen has been proposed as a surrogate marker of HCV replication. HCV core antigen detection and quantification can thus theoretically be used instead of nucleic acid testing (NAT) to diagnose infection and manage antiviral therapy, with several advantages compared to HCV RNA assays. HCV core antigen can now be easily detected and quantified by means of...
