HIV infection accelerates natural course of HCV infection, but impact of antiretroviral treatment on HCV infection is not well known. The aim of this study is to compare the change of HCV viral load in patients on combination of 2 nucleoside analogues and in patients on combination of 2 nucleoside analogues and protease inhibitor. HCV and HIV viral load, lymphocyte CD4 counts, alanine aminotransferase (ALT) and aspartate amino transferase (AST) were measured before and 3 months after starting treatment in 2 groups: Group 1 (n = 15) treated with 2 nucleoside analogues and Group 2 (n = 15) treated with 2 nucleoside analogues and a protease inhibitor. Results show a significant increase in lymphocyte and a significant decrease in HIV viral load in the both group but no significant change in HCV viral load and in ALT and AST. In conclusion efficiency of anti-HIV therapy (combination of 2 nucleoside analogues with or without a protease inhibitor) doesn't seem to have any impact on the course of HCV viremia in HIV-coinfected patients.

Background And Objective: Periodontitis and dental caries are among the most prevalent oral diseases, with chronic periodontitis being a multifactorial, infectious condition that leads to inflammation in the supporting structures of the teeth, progressive attachment loss, and bone resorption. Chronic periodontitis is driven by a consortium of pathogenic microorganisms. This study aimed to evaluate the efficacy of virgin coconut oil (VCO) pulling in reducing the microbial load and inflammatory mediators responsible for chronic periodontitis, in comparison to chlorhexidine (CHX) mouthwash and distilled water.

Prenatal and intrapartum invasive tests are possible mechanisms of mother to child transmission (MTCT) of hepatitis B virus (HBV). The viral activity can affect the MTCT risk after invasive tests, but the evidence is scarce. This scoping review discussed the effects of prenatal or intrapartum invasive tests on the risk of HBV MTCT.

The global HIV epidemic remains a major public health challenge, with DTG playing a key role in ART regimens due to its efficacy and tolerability. This study evaluated virological outcomes and resistance mutations in patients on DTG in Mozambique through a retrospective cohort study in seven DREAM centers. Data from 29,601 patients (98.

HIV-1 envelope broadly neutralizing antibodies represent a promising component of HIV-1 cure strategies. To evaluate the therapeutic efficacy of combination monoclonal antibodies (mAbs) in a rigorous nonhuman primate model, we tested different combinations of simian immunodeficiency virus (SIV) neutralizing mAbs in SIVmac251-infected rhesus macaques. Antiretroviral therapy-suppressed animals received anti-SIV mAbs targeting multiple Env epitopes spanning analytical treatment interruption (ATI) in 3 groups (n = 7 each): i) no mAb; ii) 4-mAb combination; and iii) 2-mAb combination.

Background: It remains unclear whether physicians should accept transplantation offers for candidates with a positive SARS-CoV-2 reverse transcription polymerase chain reaction test due to the potential risk of severe infection after initiating immunosuppressive therapy.
Methods: A multicenter observational study was conducted in 19 French solid organ transplantation units. Patients on the waiting list for liver or kidney transplants who had a positive SARS-CoV-2 reverse transcription polymerase chain reaction nasopharyngeal swab at the time of transplantation were recorded.
