Detection of Hbv Dna By Direct Pcr Protocol And Nested Pcr Protocol And Comparing Them. In Chronic Patients and Healthy Carriers of Hepatitis B Virus.

Hepatitis B virus is a major public health problem, and the outcome of infection depends on the effectiveness of the virus's interaction with the host, and in particular on the strength of the natural and conditioned response of humoral and cellular immunity. This study was conducted to assess the clinical status, genetic immunity and viral (viral) traits of Iraqi patients with chronic hepatitis B virus and healthy carriers of hepatitis B surface antigen, as well as to show the relationship between the immune status and the chronic condition of the disease. The study included (60) patients with chronic hepatitis B virus type (B) and (60) healthy hepatitis B surface antigen carriers who attended the Teaching Hospital for Gastrointestinal and Liver Diseases in Nasiriya City Al-Hussein Teaching Hospital, Thalassemia Center and the Central Blood Bank in Nasiriya Citysouthern of Iraq. for the period from the first period. From February 2022 until the end of February 2022, the average age of patients infected with chronic hepatitis B virus was 64.5 years, and the average age of healthy carriers of hepatitis B surface antigen was 35. 1 year, and the ratio of males to females was (12.2:) for chronic patients and (13.6:) for carriers of the disease. As for the deoxyribonucleic acid, it was (100%) in chronic patients and healthy carriers using the Nested type polymerase chain reaction, and at a rate of (30.0%) and (46.7%) in chronic patients and healthy carriers, respectively using the polymerase chain reaction technique. direct with a significant difference between the two interactions. The current results confirm that a nested PCR protocol to detect HBV DNA is a more sensitive way of detecting HBV in Iraq CHB patients and carriers. Recent advanced techniques such as nucleic acid assays, quantitative assays for viral load and RT-PCR for Iraqi viral hepatitis laboratories are recommended.
