چکیده
Background and Objective: The drug resistance mutations are key elements in the failure of long-term treatment of Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) infections. The mutation in the YMDD motif in the P gene of HBV is the most critical factor in antiviral drug (especially lamivudine) resistance. This study aimed to assess the YMDD motif and other polymerase gene mutations in individuals with HBV/HIV coinfection. Materials and Methods: All enrolled patients were under lamivudine treatment. Blood samples were collected from ۳۷ HBV/HIV-positive patients, and DNA was extracted. The P gene was amplified by the PCR method with appropriate primers. The PCR products for detecting mutations in the P gene were sent to the Macrogen. To investigate the P gene mutations, the obtained sequences were compared with the polymerase gene of the HBV standard sequence in the GeneBank (accession number AB۰۳۳۵۵۹). Results: The mean age of the patients was ۳۴.۱±۵.۷ years, of which ۵۹.۵% were male, and ۴۰.۵% were female. Of all patients, ۵۶% were drug abusers, ۳۵% had risky sexual behavior, ۵۶% had prison history, and ۳۳% had addicted wives. The ۳۷ extracted samples were sequenced successfully. Among the studied samples (n =۳۷), ۲۸ patients had simultaneous mutations of YIDD and FLMAQ, ۱ patient had YINN and FLIPH and ۱ patient had YIDD and FSLAQ. Conclusion: In summary, drug-resistant variants were detectable in most coinfected patients with chronic Hepatitis B (CHB) and HIV. As a result of mutations, therapeutic strategies sometimes are not effective. Therefore, recognition and monitoring of drug resistance mutations are critical.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
