Salivary virome is important for oral ecosystem, but there are few reports on people living with HIV. We performed metagenomic sequencing to compare composition and functional genes of salivary virobiota between one HIV-negative and four HIV-positive groups in which participants were all men who have sex with men (MSM) with different immunosuppression statuses (five samples per group) to find the evidence that salivary virobiota plays a role in the pathogenesis of oral disease. Acute-stage subjects achieved a positive result of HIV RNA, but HIV antibody negative or indeterminate, whereas individuals with mild, moderate, and severe immunosuppression exhibited CD4+ T-lymphocyte counts of at least 500, 200–499, and less than 200 cells/μL or opportunistic infection, respectively. The results showed the composition of salivary virus genera in subjects with mild immunosuppression was the most similar to that in healthy people, followed by that in the acute stage; under severe immunosuppression, virus genera were suppressed and more similar to that under moderate immunosuppression. Furthermore, abnormally high abundance of Lymphocryptovirus was particularly obvious in MSM with HIV infection. Analysis of KEGG Pathway revealed that Caulobacter cell cycle, which affects cell duplication, became shorter in HIV-positive subjects. It is worth noting that in acute-stage participants, protein digestion and absorption related to the anti-HIV-1 activity of secretory leukocyte protease inhibitor was increased. Moreover, in the severely immunosuppressed subjects, glutathione metabolism, which is associated with the activation of lymphocytes, was enhanced. Nevertheless, the ecological dysbiosis in HIV-positive salivary virobiota possibly depended on the changes in blood viral load, and salivary dysfunction of MSM infected with HIV may be related to CD4 counts. Ribonucleoside diphosphate reductase subunit M1 in purine metabolism was negatively correlated, though weakly, to CD4 counts, which may be related to the promotion of HIV-1 DNA synthesis in peripheral blood lymphocytes. 7-Cyano-7-deazaguanine synthase in folate biosynthesis was weakly positively correlated with HIV viral load, suggesting that this compound was produced excessively to correct oral dysfunction for maintaining normal cell development. Despite the limited number of samples, the present study provided insight into the potential role of salivary virome in the oral function of HIV infected MSM.

PURPOSE: To morphometrically quantify CD1a+ dentritic cells and DC-SIGN+ dendritic cells in HIV-positive patients with anal squamous intraepithelial neoplasia and to evaluate the effects of HIV infection, antiretroviral therapy and HPV infection on epithelial and subepithelial dendritic cells. METHODS: A prospective study was performed to morphometrically analyze the relative volume of the dendritic cells and the relationship between anal intraepithelial neoplasia and cancer in HIV-positive patients from the Tropical Medicine Foundation of Amazonas, Brazil. All patients were submitted to biopsies of anorectal mucosa to perform a classic histopathological and immunohistochemical analysis, employing antibodies against CD1a and DC-SIGN for the morphometric quantification of dendritic cells. RESULTS: HIV-negative patients displayed a CD1a DC density significantly higher than that of HIV-positives patients (3.75 versus 2.54) (p=0.018), and in patients with severe anal intraepithelial neoplasia had correlated between DC CD1a density with levels of CD4 + cells (p: 0.04) as well as the viral load of HIV-1 (p: 0.035). A not significant rise in the median density of CD1a+ DC was observed in the HIV positive/ HAART positive subgroup compared to the HIV positive/ HAART negative subgroup. The CD1a+ DC were also significantly increased in HIV-negative patients with anorectal condyloma (2.33 to 3.53; p=0.05), with an opposite effect in HIV-positive patients. CONCLUSIONS: Our data support an enhancement of the synergistic action caused by HIV-HPV co-infection on the anal epithelium, weakening the DC for its major role in immune surveillance. Notoriously in patients with severe anal intraepithelial neoplasia, the density of CD1a+ epithelial dendritic cells was influenced by the viral load of HIV-1. Our study describes for the first time the density of subepithelial DC-SIGN+ dendritic cells in patients with anal severe anal intraepithelial neoplasia and points to the possibility that a specific therapy for HIV induces the recovery of the density of epithelial DC.

Introduction: The spate of non-disclosure among individuals diagnosed with Human-Immunodeficiency-Virus and Acquired-Immune-Deficiency-Syndrome (HIV/AIDS) has continually been a primary global concern, especially in developing countries. Meta-analysis findings in Nigeria reported poor disclosure rates of 12.5% - 39.5%, which were far below the average disclosure benchmark of 79.0% standard stipulated for developing nations by the World Health Organization. There is no consensus regarding the roles of CD4 counts in disclosure intention. In Nigeria, there is a paucity of literature providing detailed understanding of the predictors of disclosure intention by the duration of diagnosis knowledge and CD4 counts. Methods: This study, therefore, investigated the implication of duration of diagnosis knowledge and CD4 counts in the prediction of HIV disclosure intention among people seeking HIV treatment. Longitudinal survey research designs were adopted. 390 participants were purposively selected to respond to HIV Self-Disclosure Intention Index (α=0.92), while information on CD4 counts and Duration of Diagnosis Knowledge was obtained from the selected respondents’ case files periodically. Binomial logistic regression analysis was used to analyze data at 0.05. Respondents’ mean age was 39.5±10.5 years. Results: Findings revealed that the duration of diagnosis knowledge and CD4 counts interactively predicted the outcome of disclosure intention among treatment-seeking PLHIV. (χ2 = 12.78, df = 2, p < 0.001) and further showed that the likelihood of disclosing HIV positive status increases by 13% between Time 1 (OR = -0.49, p < 0.01; 95%CI = 01.14-12.74) and Time 2 (OR = -0.36, p < 0.05; 95%CI = 01.11-10.93). Increase in CD4 counts was also found to increase the likelihood of HIV self-disclosure by 15% between Time 1 (OR = - 0.84, p < 0.01; 95%CI = 01.09-03.06) and Time 2 (OR = - 0.99, p < 0.01; 95%CI = 00.29-03.06). Conclusion: It was concluded that the duration of diagnosis knowledge and CD4 counts have significant implications in determining the intention to disclose HIV positive status. The study limitations and recommendations were further discussed.

Epstein Barr Virus (EBV) and Human Herpes Virus 6 (HHV-6) are responsible for severe diseases, particularly in immunocompromised persons. There are poor data on the infection with these opportunistic viruses in Burkina Faso.The purpose of this study is to characterize EBV and HHV-6 subtypes and to assess their impact on CD4 T cell count, HIV-1 viral load and antiretroviral treatment in people living with HIV-1.The study population consisted of 238 HIV-positive patients with information on CD4 count, HIV-1 viral load and HAART. Venous blood samples collected on EDTA tubes were used for EBV and HHV-6 Real Time PCR subtyping.An infection rate of 6.7% (16/238) and 7.1% (17/238) were found respectively for EBV and HHV-6 in the present study. Among EBV infections, similar prevalences were noted for both subtypes (3.9% [9/238] for EBV-1 vs 4.6% [11/238] for EBV-2) with 2.1% (5/238) of co-infection. HHV-6A infection represented 6.3% (15/238) of the study population against 5.0% (12/238) for HHV-6B. . EBV-2 infection was significantly higher in patients with CD4 count ≥ 500 compared to those with CD4 count less than 500 cells (1.65% vs 8.56%, p = 0,011). The prevalence of EBV and HHV-6 infections were almost similar in HAART-naive and HAART-experienced patients.The present study provides information on the prevalence of EBV and HHV-6 subtypes in people living with HIV-1 in Burkina Faso. The study also suggests that HAART treatment has no effect on infection with these opportunistic viruses in people living with HIV-1.

With reports of increasing syphilis rates among men who have sex with men in various countries and complications such as ocular syphilis and neurosyphilis, greater efforts for promoting frequent syphilis screening of higher risk men are required. This should include serological testing for syphilis every time HIV testing is undertaken and each time HIV viral load testing is performed in HIV-positive men who have sex with men. Systems-based approaches tailored to particular contexts should be explored, evaluated and, if shown to be effective, implemented.

Plasma HIV-1 RNA concentration, or viral load, is an indication of the magnitude of virus replication and largely correlates with disease progression in an infected person. It is a very useful guide for initiation of therapy and monitoring of response to antiretroviral drugs. Although the majority of patients who are not on antiretroviral therapy (ART) have a high viral load, a small proportion of ART naive patients are known to maintain low levels or even undetectable viral load levels. In this study, we determined the rate of undetectable HIV-1 RNA among ART naive HIV positive patients who presented for treatment at the University College Hospital (UCH), Ibadan, Nigeria from 2005 to 2011. Baseline viral load and CD4 lymphocyte cell counts of 14,662 HIV positive drug naive individuals were determined using the Roche Amplicor version 1.5 and Partec easy count kit, respectively. The detection limits of the viral load assay are 400 copies/mL and 750,000 copies/mL for lower and upper levels, respectively. A total of 1,399 of the 14,662 (9.5%) HIV-1 positive drug naive individuals had undetectable viral load during the study period. In addition, the rate of non-detectable viral load increased over the years. The mean CD4 counts among HIV-1 infected individuals with detectable viral load (266 cells/μL; range = 1 to 2,699 cells/μL) was lower than in patients with undetectable viral load (557 cells/μL; range = 1 to 3,102 cells/μL). About 10% of HIV-1 infected persons in our study population had undetectable viral load using the Roche Amplicor version 1.5.

Background: Antiretroviral therapy (ART) has significantly increased the lifespan of people living with HIV. Currently, fixed dosed combination therapy (Tenofovir, Lamivudine, and Dolutegravir) is being introduced in most countries in the Sub- Saharan Africa. There is need for a clinical and immunological assessment of HIV patients transitioned to this new therapy over a period of 2 years. Objectives: To determine the proportion of patients whose viral load was suppressed to <20 copies/ml following two years therapy with Dolutegravir-based fixed-dose combination therapy. Methods: This retrospective cohort study was carried out in a Comprehensive Healthcare Centre (CHC), a facility affiliated with Nnamdi Azikiwe University Teaching Hospital Nigeria. The primary outcome measure was the proportion of patients whose viral load was suppressed to <20 copies/ml. The plasma viral load (HIV-RNA) assay was done using real time PCR and CD4+ T- lymphocyte (CD4+) counts were estimated using Flow Cytometry. The exclusion criteria were patients who has invalid data base and patients with comorbidities associated with HIV. Results: A total of 537 HIV1 sero-positive patients were enrolled for ART care over a period of 2 years (2017-2018). Females in the age group (41-50 years) constituted the bulk (36.9%) of the patients whilst the least (5.3%) were males in the age group (8 to 30 years). The mean CD4 count of patients was 847.35cells/mm3. More females (45.9%) had CD4+counts over 500cells/mm3 whilst the percentage of males with CD4+ cell counts over 500cells/mm3 was 43.8%. Majority, 405 constituting 75.4% of the patients have suppressed viral load (<20 copies/ml) signifying that the centre is achieving success with respect to service delivery and ART. Patients with unsuppressed viral loads were more among Females with CD4+ counts in the range of 200-499 cells/mm3and this may be as a result of other associated factors which will be elucidated in future studies. Conclusion: Dolutegravir-based fixed-dose combination therapy suppressed viral load to <20 copies/ml in more than 75% of patients receiving the therapy. Enhanced adherence and effective doctor-patient relationship could be associated with the viral suppression observed in this study. Key words: Immunology, virology, HIV Outcome, Dolutegravir-based combination therapy, anti retroviral therapy.
