Abdalla AL, Guajardo-Contreras G, Mouland AJ. A Canadian Survey of Research on HIV-1 Latency-Where Are We Now and Where Are We Heading? Viruses 2024; 16:229. [PMID: 38400005 PMCID: PMC10891605 DOI: 10.3390/v16020229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 01/26/2024] [Accepted: 01/30/2024] [Indexed: 02/25/2024] Open
Abstract
Worldwide, almost 40 million people are currently living with HIV-1. The implementation of cART inhibits HIV-1 replication and reduces viremia but fails to eliminate HIV-1 from latently infected cells. These cells are considered viral reservoirs from which HIV-1 rebounds if cART is interrupted. Several efforts have been made to identify these cells and their niches. There has been little success in diminishing the pool of latently infected cells, underscoring the urgency to continue efforts to fully understand how HIV-1 establishes and maintains a latent state. Reactivating HIV-1 expression in these cells using latency-reversing agents (LRAs) has been successful, but only in vitro. This review aims to provide a broad view of HIV-1 latency, highlighting Canadian contributions toward these aims. We will summarize the research efforts conducted in Canadian labs to understand the establishment of latently infected cells and how this informs curative strategies, by reviewing how HIV latency is established, which cells are latently infected, what methodologies have been developed to characterize them, how new compounds are discovered and evaluated as potential LRAs, and what clinical trials aim to reverse latency in people living with HIV (PLWH).

Adherence, adverse drug reactions, and discontinuation associated with adverse drug reactions of HIV post-exposure prophylaxis: a meta-analysis based on cohort studies. Ann Med 2023; 55:2288309. [PMID: 38065681 PMCID: PMC10836249 DOI: 10.1080/07853890.2023.2288309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 11/21/2023] [Indexed: 12/18/2023] Open
Abstract
Objective: Evaluate the profiles of post-exposure prophylaxis (PEP) adherence, adverse drug reactions (ADRs), and discontinuation associated with ADRs to provide information for further PEP program improvement and increase adherence to PEP.Methods: The Web of Science, PubMed, Embase, and the Cochrane Library were searched for cohort studies reporting data related to PEP adherence or ADRs (PROSPERO, CRD42022385073). Pooled estimates of adherence, the incidence of ADRs and discontinuation associated with ADRs, and their 95% confidence intervals (CI) were calculated separately for the included literature using random effects models. For substantial heterogeneity, meta-regression and subgroup analyses were conducted to explore sources of heterogeneity.Results: Overall adherence was 58.4% (95% CI: 50.9%-65.8%), with subgroup analysis showing differences in adherence across samples, with the highest adherence among men who had sex with men (MSM) (72.4%, 95% CI: 63.4%-81.3%) and the lowest adherence among survivors of sexual assault (SAs) (41.7%, 95% CI: 28.0%-55.3%). The incidence of ADRs was 60.3% (95% CI: 50.3%-70.3%), and the prevalence of PEP discontinuation associated with ADRs was 32.7% (95% CI: 23.7%-41.7%), with subgroup analyses revealing disparities in the prevalence of discontinuation associated with ADRs among samples with different drug regimens. Time trend analysis showed a slight downward trend in the incidence of ADRs and PEP discontinuation associated with ADRs.Conclusion: Adherence to PEP was less than 60% across samples, however, there was significant heterogeneity depending on the samples. SAs had the lowest adherence and the highest incidence of PEP discontinuation. Ongoing adherence education for participants, timely monitoring, and management of ADRs may improve adherence.

Risk perception and usage of non-occupational post-exposure prophylaxis among fisherfolk in Ggulwe parish on the shores of Lake Victoria in central Uganda. Front Public Health 2023; 11:1116317. [PMID: 38026329 PMCID: PMC10663348 DOI: 10.3389/fpubh.2023.1116317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 10/10/2023] [Indexed: 12/01/2023] Open
Abstract
Background The use of non-occupational post-exposure prophylaxis (nPEP) to prevent HIV acquisition among those exposed as an approach to HIV prevention has expanded in Uganda. Although there are increased efforts to avail nPEP services among most at-risk populations, the usage of nPEP medicines remains low. Therefore, this study examined the risk perception and usage of non-occupational post-exposure prophylaxis (nPEP) among fisherfolk in the Ggulwe fishing parish, Bussi sub-county, Wakiso district. Methods A cross-sectional study among adults was carried out from October 2020 to January 2021 in Ggulwe parish, Bussi sub-county, Wakiso district, to examine the usage of nPEP and factors influencing the usage. Data were collected using semi-structured questionnaires, and key informants' interviews were conducted among healthcare providers and the local leadership. The quantitative data were summarized using bivariate and multivariate logistic regression, while the qualitative data were analyzed thematically to enrich the quantitative results. Results Overall, 248 fisherfolk encountered an event that required the use of nPEP, and of these, 55/248 (22.2%) were able to use nPEP to prevent them from acquiring HIV. The usage of nPEP among adults in the Bussi sub-county, Wakiso district, was associated with not knowing that HIV can be prevented using nPEP medicines (AOR:0.1, 95% CI 0.03-0.36, p < 0.001), lack of knowledge of the existence of nPEP (AOR: 0.3, 95% CI 0.13-0.76, p = 0.01), the perception that nPEP can effectively prevent HIV infection after exposure (AOR 0.0586, 95% CI: 0.0177-0.1944, p < 0.001), and the community's opinion affecting the willingness to take nPEP (AOR 0.1924, 95% CI: 0.0380-0.9727, p = 0.0462). Conclusion The usage of nPEP among fisherfolk was low (22.2%). The low usage of nPEP was associated with a lack of knowledge and awareness about nPEP. This effort to improve the usage of nPEP should include community sensitization and HIV infection prevention using nPEP to raise awareness about HIV infection exposures and the risk of HIV infection during non-occupational exposures.

Abstract
The current prevention efforts for STIs, HIV and viral hepatitis in the WHO European Region, especially in the Central and Eastern subregions, are hindered by healthcare disparities, data gaps, and limited resources. In this comprehensive narrative review, we aim to highlight both achievements and persisting challenges while also exploring new developments that could significantly impact the prevention of these infections in the near future. While pre-exposure prophylaxis (PrEP) for HIV has been broadly approved and implemented in 38 out of 53 countries in the region, challenges remain, including cost, limited licensing, and incomplete adherence. We explore innovative approaches like on-demand PrEP, long-acting injectable cabotegravir, and intravaginal rings that have shown promising results, alongside the use of six-monthly lenacapavir, the outcomes of which are pending. Additionally, the potential of doxycycline post-exposure prophylaxis has been discussed, revealing efficacy in reducing chlamydia and syphilis risk, but effectiveness against gonorrhoea being contingent on tetracycline resistance rates, and the need of further data to determine potential resistance development in other bacteria and its impact on the gut microbiome. We examine successful vaccination campaigns against HBV and HPV, the ongoing development of vaccines for chlamydia, syphilis, herpesvirus, and gonorrhoea, and challenges in HIV vaccine research, including lines of research with significant potential like sequential immunization, T-cell responses, and mRNA technology. This review underscores the research endeavors that pave the way for a more resilient and robust approach to combating STIs, HIV, and viral hepatitis in the region.

HIV awareness and prevention strategies among transgender women in the Eastern and Southern United States: findings from the LITE Study. J Int AIDS Soc 2022; 25 Suppl 5:e25999. [PMID: 36225140 PMCID: PMC9557018 DOI: 10.1002/jia2.25999] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Accepted: 07/30/2022] [Indexed: 11/28/2022] Open
Abstract
INTRODUCTION Transgender women (TW) experience an increased risk of human immunodeficiency virus (HIV) acquisition. This study identified patterns of HIV awareness and prevention strategies used by TW who were not living with HIV. METHODS Data were drawn from a baseline survey of the LITE Study, a multi-site cohort of TW in Eastern and Southern United States (March 2018-August 2020). We conducted a latent class analysis to identify classes of HIV awareness and prevention strategies among TW who reported past 12-month sexual activity (N = 958) using 10 variables spanning HIV knowledge, receipt and use of HIV prevention strategies, and sexual practices. Due to differences across the cohort arms, classes were estimated separately for TW enrolled in site-based versus online study arms. We identified demographic characteristics, gender-affirming indicators and HIV vulnerabilities associated with class membership. RESULTS Four parallel classes emerged: class 1 "limited strategies-less sexually active" (15% and 9%, site-based and online, respectively), class 2 "limited strategies-insertive sex" (16%/36%), class 3 "limited strategies-receptive sex" (33%/37%) and class 4 "multiple strategies-insertive and receptive sex" (36%/18%). Across all classes, condomless sex, pre-exposure prophylaxis (PrEP)/post-exposure prophylaxis (PEP) prevention knowledge and awareness were high but reported PrEP/PEP use was low. Compared with class 1, membership in class 4 was associated with being a person of colour (site-based OR = 2.15, 95% CI = 1.15-4.00, online OR = 4.54, 95% CI = 1.09-18.81) increased odds of self-perceived medium-to-high HIV risk (site-based OR = 4.12, 95% CI = 2.17-7.80, online OR = 11.73, 95% CI = 2.98-46.13), sexually transmitted infections (STI) diagnosis (site-based OR = 6.69, 95% CI = 3.42-13.10, online OR = 8.46, 95% CI = 1.71-41.78), current sex work (site-based OR = 6.49, 95% CI = 2.61-16.11, online OR = 10.25, 95% CI = 1.16-90.60) and 2-4 sexual partners in the last 3 months (site-based OR = 2.61, 95% CI = 1.33-5.13). Class 3, compared with class 1, had increased odds of current sex work partners (site-based OR = 3.09, 95% CI = 1.19-8.07) and of having 2-4 sexual partners in the last 3 months (site-based OR = 3.69, 95% CI = 1.85-7.39). CONCLUSIONS TW have varied HIV awareness and prevention strategy utilization, with clear gaps in the uptake of prevention strategies. Algorithms derived from latent class membership may be used to tailor HIV prevention interventions for different subgroups and those reached through facility-based or digital methods.

Abstract
The high burden of HIV in sub-Saharan Africa places significant demands on health care services. Interventions such as HIV self-testing, and pre- and post-exposure prophylaxis (PrEP and PEP) could empower individuals to determine their HIV status and prevent HIV acquisition. In 2018, the World Health Organization disseminated an online, anonymous, global values and preferences survey to adults 18 years of age and older. The survey aimed to inform guidance on awareness, use, and preferences around self-care interventions for sexual and reproductive health. We conducted a cross-sectional analysis using Pearson's chi-squared test to compare awareness of HIV self-testing, PrEP and PEP across five global regions. Our analysis included 814 participants from 110 countries. We noted that respondents from Africa reported higher awareness of HIV interventions than participants from Europe, Latin America and the Caribbean, North America, and Asia. Our finding highlights an opportunity to expand self-care interventions for HIV prevention and management in Africa.

Abstract
BACKGROUND Although a few studies have assessed occupational exposure and knowledge on post-exposure prophylaxis (PEP) for HIV among health care workers (HCWs), limited information is available on the factors that influence the use of HIV PEP among HCWs after occupational exposure in Cameroon. This study aimed to assess the prevalence and determinants of occupational exposure to HIV infection and identify factors (knowledge, attitudes, and practices) that influence compliance to the use of HIV PEP among HCWs in the Biyem-Assi, Buea, and Limbe health districts. METHODS A stratified cross-sectional study was carried out among health care workers from the Biyem-Assi, Buea, and Limbe health districts of Cameroon. A structured questionnaire adapted from previous studies was administered on the socio-demographic status, occupational exposure to biological agents as well as information on knowledge, awareness of PEP guidelines, attitude, and practice of the HCWs towards HIV PEP. RESULTS Of the 312 participants, 198 (63.5%) experienced an occupational injury, and 240 (76.9%) had a good attitude towards HIV PEP. Age, place of work, and inadequate knowledge were determinants of occupational exposure. Whereas, awareness of PEP guidelines and being a medical doctor influenced compliance with HIV PEP, with 158 (51.0%) having adequate knowledge of the guidelines. Out of the 198 who experienced occupational injury, 114 (57.6%) adopted the good practice and 60 (30.3%) made use of HIV PEP. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS Over half of health care workers had occupational exposure to HIV with poor utilization of post-exposure prophylaxis though they were aware and knowledgeable of PEP guidelines and exhibited good practice. Compliance with HIV PEP utilization was influenced by gender, awareness of PEP guidelines, and specialty of the health care worker.

Abstract
Objective To investigate the quantity of CD4+T, CD4+T, CD8+T, and γδT cells in peripheral blood of HIV-infected/AIDS patients as well as to explore the possible role of CD4/CD8 ratio and γδT cells in the progression of HIV/AIDS, aimed at providing evidence for the diagnosis and treatment of AIDS. Methods The quantity levels of CD3+T cells, CD4+T cells, CD8+T cells, and γδT cells in peripheral blood of 46 HIV-infected/AIDS patients and 30 healthy controls were detected by using flow cytometry. Results The count of CD3+T, CD4+T, CD8+T, and γδT cells (x¯±s, A/μl) in the peripheral blood was 1183.64 ± 132.58, 278.39 ± 122.38, 863.13 ± 82.38, and 22.53 ± 1.74 in the experimental group as well as 1456.46 ± 124.37, 788.74 ± 189.67, 569.61 ± 46.49, and 10.96 ± 0.28 in the control group, respectively. The p values of the two groups were <0.005 after the t-test, revealing a statistically significant difference. The proportion of CD3+T, CD4+T, CD8+T, and γδT cells in total lymphocytes in the two groups (x¯±s, %) was 71.83 ± 5.37, 13.39 ± 2.23, 62.93 ± 5.81, and 3.67 ± 0.87 in the experimental group, respectively. In the control group, the values were expressed as 66.72 ± 5.48, 42.77 ± 3.38, 31.41 ± 3.62, and 1.73 ± 0.36, respectively. After performing the t-test, p values in the two groups were <0.005 except CD3+T, with statistically significant differences. Besides, CD4/CD8 was 0.33 ± 0.11 in the experimental group and 1.48 ± 0.29 in the control group, t = 26.528, p < 0.001, exhibiting a significant statistical difference. Conclusion HIV infection induces the activation and proliferation of CD8+T and γδT cells, contributing to the decrease of CD4+T cells, while CD8+T and γδT cells are involved in the immune response and tissue damage after HIV infection.

Abstract
INTRODUCTION in the review, we aimed to present current knowledge about the risk of infection, standards of care, and postexposure prophylaxis (PEP) in pediatric patients after non-vertical exposures to HIV, HBV, and HCV infection. MATERIALS AND METHODS the latest available literature and recommendations of Centers for Disease Control and Prevention (CDC), World Health Organization (WHO), European recommendations for the management of HIV and administration of non-occupational PEP, and Polish AIDS Society were reviewed. RESULTS the majority of cases of non-vertical exposure to blood-borne viruses in the pediatric population consist of sexual exposition and injection with unsterilized sharp objects (usually needlestick injuries). The risk HIV, HBV, and HCV transmission depend on several factors, and each exposure should be evaluated individually with consideration of the patient's medical history. It is crucial to start antiretroviral therapy within 48 h from exposure. Treatment is continued for 28 days, and a 3-drugs regiment is recommended in the majority of cases. Decisions on hepatitis B and tetanus PEP are based on a history of vaccination. There is no PEP for hepatitis C infection, follow-up testing aims for early identification of disease and consideration of treatment options. CONCLUSION all children after the non-vertical exposure to HIV, HBV, and HCV infection should be evaluated by the Infectious Disease specialist as soon as possible after the incident and qualified to post-exposure prophylaxis. Systematic diagnostic and follow-up on children after significant needlestick exposure should be maintained. Children after sexual exposure need a multidisciplinary approach. Response to reported event must be rapid and treatment must be comprehensive.

Platelets function as an acute viral reservoir during HIV-1 infection by harboring virus and T-cell complex formation. Blood Adv 2021; 4:4512-4521. [PMID: 32946568 DOI: 10.1182/bloodadvances.2020002420] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Accepted: 08/14/2020] [Indexed: 12/22/2022] Open
Abstract
Platelets were recently found to harbor infectious HIV virions in infected individuals who are on antiretroviral treatment with poor CD4+ T-cell recovery. In this study, we screened platelets from recently infected individuals, before and after antiretroviral therapy, for the presence of virus and examined platelet activation, as well as CD4+ T-cell recovery. This was followed by in vitro studies assessing platelet-CD4+ T-cell complex formation as a contributing factor to viral transmission. HIV+ platelets were detected in 10 of 10 acutely infected individuals with no prior history of antiretroviral therapy. The percentage of HIV+ platelets dropped significantly after 3 months of antiretroviral therapy in all of the study participants. These individuals also demonstrated significant recovery of CD4+ T cells. Interestingly, the percentage of HIV+ platelets correlated positively with viral load but not with CD4+ T-cell count. Furthermore, we found that platelet activation with soluble CD40L or thrombin receptor activator peptide 6 (TRAP6) increased platelet-virus interactions in vitro. TRAP6-mediated interactions were reduced by platelet antagonists, aspirin, and R406. We demonstrated that platelets transmit the virus to CD4+ T cells, and this transinfection was abolished by inhibiting platelet-T-cell complex formation via exposure to an anti-CD62P antibody. Additionally, treatment with TRAP6 significantly increased the transinfection, which was also inhibited by aspirin and R206. These results reveal that platelets have the potential to promote HIV viral spread during the acute stage of infection, by harboring infectious virus transmitting infection to susceptible CD4+ T cells through complex formation.

Occupational Exposure to Blood and Body Fluids and Knowledge of HIV Post-Exposure Prophylaxis among Medical and Allied Health Students in Northern Nigeria. THE INTERNATIONAL JOURNAL OF OCCUPATIONAL AND ENVIRONMENTAL MEDICINE 2020; 11:196-209. [PMID: 33098404 PMCID: PMC7740050 DOI: 10.34172/ijoem.2020.2094] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/07/2020] [Accepted: 09/13/2020] [Indexed: 12/30/2022]
Abstract
Background: Clinical students are at increased risk of exposure to blood-borne pathogens. However, little has been documented about their exposure to blood and body fluids and their knowledge of post-exposure prophylaxis (PEP) in high-HIV burden settings, such as Nigeria. Objective: To determine the prevalence and predictors of BBF exposure and knowledge about PEP among medical and allied health students in northern Nigeria. Methods: In a cross-sectional study, 273 clinical students were asked to complete structured questionnaires. The prevalence of BBF exposure was determined. Binary logistic regression was used to determine the independent predictors of BBF exposure. Results:
The majority of the respondents (98.2%) had heard about PEP; 26.0% (n=71) had adequate knowledge about PEP. 76 (27.8%) of the 273 respondents reported accidental exposure to HIV. 230 (84.2%) respondents had positive attitude toward HIV PEP. Of those who had had accidental exposure to HIV (n=76), only 13% (n=10) received PEP. The level of knowledge about PEP was predicted by previous training (aOR 0.43, 95% CI 0.23 to 0.80 ["no" vs "yes"]), year of training (aOR 4.10, 95% CI 1.60 to 10.47 [6thvs 4th year]), course of study (aOR 4.69, 95% CI 2.06 to 10.68 ["allied health" vs "clinical medicine"]) and religion (aOR 5.39, 95% CI 1.40 to 20.71 ["non-Muslim" vs "Muslim"]). Similarly, accidental exposure was independently predicted by respondents’ sex (aOR 2.55, 95% CI1.36 to 4.75 ["female" vs "male"]), age (aOR 2.54, 95% CI 1.06 to 6.15 ["25–29" vs "20–24" years]), ethnicity (aOR 2.15, 95% CI1.10 to 5.14 ["others" vs "Hausa/Fulani"]), course of study (aOR 0.06, 95% CI 0.01 to 0.38 ["allied health" vs "clinical medicine"]), and previous PEP training (aOR 0.39, 95% CI 0.20 to 0.78 ["no" vs "yes"]).
Conclusion: One in four clinical students reported exposure to BBF. Most students expressed a positive attitude toward PEP, but knowledge and uptake of PEP was sub-optimal. We recommend strengthening training curricula for infection control and prevention and enhancing protocols for timely post-exposure evaluation and follow up for all exposure incidents.

Mitochondrial Toxicogenomics for Antiretroviral Management: HIV Post-exposure Prophylaxis in Uninfected Patients. Front Genet 2020; 11:497. [PMID: 32528527 PMCID: PMC7264262 DOI: 10.3389/fgene.2020.00497] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2019] [Accepted: 04/21/2020] [Indexed: 01/09/2023] Open
Abstract
Background: Mitochondrial genome has been used across multiple fields in research, diagnosis, and toxicogenomics. Several compounds damage mitochondrial DNA (mtDNA), including biological and therapeutic agents like the human immunodeficiency virus (HIV) but also its antiretroviral treatment, leading to adverse clinical manifestations. HIV-infected and treated patients may show impaired mitochondrial and metabolic profile, but specific contribution of viral or treatment toxicity remains elusive. The evaluation of HIV consequences without treatment interference has been performed in naïve (non-treated) patients, but assessment of treatment toxicity without viral interference is usually restricted to in vitro assays. Objective: The objective of the present study is to determine whether antiretroviral treatment without HIV interference can lead to mtDNA disturbances. We studied clinical, mitochondrial, and metabolic toxicity in non-infected healthy patients who received HIV post-exposure prophylaxis (PEP) to prevent further infection. We assessed two different PEP regimens according to their composition to ascertain if they were the cause of tolerability issues and derived toxicity. Methods: We analyzed reasons for PEP discontinuation and main secondary effects of treatment withdrawal, mtDNA content from peripheral blood mononuclear cells and metabolic profile, before and after 28 days of PEP, in 23 patients classified depending on PEP composition: one protease inhibitor (PI) plus Zidovudine/Lamivudine (PI plus AZT + 3TC; n = 9) or PI plus Tenofovir/Emtricitabine (PI plus TDF + FTC; n = 14). Results: Zidovudine-containing-regimens showed an increased risk for drug discontinuation (RR = 9.33; 95% CI = 1.34–65.23) due to adverse effects of medication related to gastrointestinal complications. In the absence of metabolic disturbances, 4-week PEP containing PI plus AZT + 3TC led to higher mitochondrial toxicity (−17.9 ± 25.8 decrease in mtDNA/nDNA levels) than PI plus TDF + FTC (which increased by 43.2 ± 24.3 units mtDNA/nDNA; p < 0.05 between groups). MtDNA changes showed a significant and negative correlation with baseline alanine transaminase levels (p < 0.05), suggesting that a proper hepatic function may protect from antiretroviral toxicity. Conclusions: In absence of HIV infection, preventive short antiretroviral treatment can cause secondary effects responsible for treatment discontinuation and subclinical mitochondrial damage, especially pyrimidine analogs such as AZT, which still rank as the alternative option and first choice in certain cohorts for PEP. Forthcoming efforts should be focused on launching new strategies with safer clinical and mitotoxic profile.

Abstract
Background Human immunodeficiency virus (HIV) infection is a serious public health problem costing the lives of many people including healthcare workers worldwide. Ethiopia is one of the most seriously affected countries in sub-Saharan Africa, with a large number of people who are living with HIV/AIDS and AIDS -related deaths. Prevention of the virus transmission through the appropriate utilization of post exposure prophylaxis is one of the major strategies. Therefore, the aim of this study was to evaluate the utilization of post-exposure prophylaxis (PEP) among victims of HIV at the University of Gondar Comprehensive Specialized Hospital, north-west Ethiopia. A retrospective cross-sectional study was conducted from May 17, 2018, to May 24, 2018 and descriptive statistics were carried out to analyze the Data using SPSS version 20. Results From a total of 309 patients PEP was prescribed during the study period, of whom 239 (77.34%) were occupational victims and 55 (17.8%) were rape victims, with one missing data. Occupational victims were exposed by blood and blood product splashes and nurses and physicians were exposed almost equally, 14.24% and 13.92%, respectively. The majority of the victims were exposed at a health facility. Two hundred and eighty-five (92.23%) victims received prescriptions containing three-drug regimens, tenofovir + lamivudine + efavirenz, followed by 9 victims (2.91%) with two-drug regimens; zidovudine + lamivudine. There are no follow-up mechanisms as a result the completion rate and the outcome of PEP was not determined. Conclusion PEP was initiated within 72 hr, most within 24 hr. The adherence was unknown with poor follow-up despite the strong recommendations of the national and WHO guidelines.

Abstract
Combination antiretroviral therapy (cART) is effective but not curative, and no successful vaccine is currently available for human immunodeficiency virus-1 (HIV-1). Broadly neutralizing antibodies (bNAbs) provide a new approach to HIV-1 prevention and treatment, and these promising candidates advancing into clinical trials have shown certain efficacies in infected individuals. In addition, bNAbs have the potential to kill HIV-1-infected cells and to affect the course of HIV-1 infection by directly engaging host immunity. Nonetheless, challenges accompany the use of bNAbs, including transient suppression of viraemia, frequent emergence of resistant viruses in rebound viraemia, suboptimal efficacy in virus cell-to-cell transmission, and unclear effects on the cell-associated HIV-1 reservoir. In this review, we discuss opportunities and potential strategies to address current challenges to promote the future use of immunotherapy regimens.

Abstract
Vertical transmission accounts for most human immunodeficiency virus (HIV) infection in children, and treatments for newborns are needed to abrogate infection or limit disease progression. We showed previously that short-term broadly neutralizing antibody (bNAb) therapy given 24 h after oral exposure cleared simian-human immunodeficiency virus (SHIV) in a macaque model of perinatal infection. Here, we report that all infants given either a single dose of bNAbs at 30 h, or a 21-day triple-drug ART regimen at 48 h, are aviremic with almost no virus in tissues. In contrast, bNAb treatment beginning at 48 h leads to tight control without adaptive immune responses in half of animals. We conclude that both bNAbs and ART mediate effective post-exposure prophylaxis in infant macaques within 30-48 h of oral SHIV exposure. Our findings suggest that optimizing the treatment regimen may extend the window of opportunity for preventing perinatal HIV infection when treatment is delayed.

Abstract
BACKGROUND Burkina-Faso's HIV/AIDS program is one of the most successful in Africa, with a declining HIV prevalence and treatment outcomes that rival those of developed countries. Prevention of mother-to-child transmission (PMTCT) guidelines in Burkina-Faso, initiated in the year 2000, were revised in 2004, 2006 and 2010. The guideline document has since undergone several stages of improvement, largely based on recommendations from WHO, with adaptations by local experts in the field. Option B+ adopted since August 2014 in Burkina-Faso has enabled maintenance of mothers on longer treatment and increasing their survival and that of their children. Through this review, we describe the achievements and challenges of HIV PMTCT programs in Burkina-Faso. AIMS OF STUDY This study had the following objectives: 1) describing the historical perspective of PMTCT implementation in Burkina-Faso; 2) presenting the effectiveness of interventions at improving PMTCT service delivery and promoting retention of mothers and babies in care; and 3) determining the impact of male partner involvement on PMTCT in Burkina-Faso. METHODOLOGY A literature search was conducted in PubMed and Google. Search terms included the following keywords: "HIV testing"; "prevention"; "mother"; "child"; "male partner"; "counseling"; "involvement"; "participation"; and the grouped terms "PMTCT and partners"; "VCT"; "barriers and/or factors"; "Male involvement in PMTCT"; and "Burkina-Faso". Data collection took place from May to October 2015. The search was limited to articles published between January 2002 and December 2015. UNICEF and UNAIDS web sites were also used to find relevant abstracts and documents. RESULTS Studies have revealed that with PMTCT, HIV transmission rate moved from 10.4% in 2006 to 0% in 2015. The PMTCT program remains the best way to care for HIV-infected pregnant women and their babies. The current PMTCT policy is based on evidence that male partner involvement is associated with women's completion of PMTCT. CONCLUSION This study shows that the reduction in mother to child transmission of HIV in Burkina-Faso over the years is mainly due to the improvement of PMTCT programs. Efforts still need to be made about the involvement of male partners.

Abstract
The presence of cells latently infected with HIV is currently considered to be a major barrier to viral eradication within a patient. Here, we consider birth-death-immigration models for the latent cell population in a single patient, and present analytical results for the size of this population in the absence of treatment. We provide results both at steady state (viral set point), and during the non-equilibrium setting of early infection. We obtain semi-analytic results showing how latency-reversing drugs might be expected to affect the size of the latent pool over time. We also analyze the probability of rare mutant viral strains joining the latent cell population, allowing for steady-state and dynamic viral populations within the host.

[PMID: 29899881 PMCID: PMC5981229 DOI: 10.4103/ijpvm.ijpvm_217_16] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2016] [Accepted: 11/30/2017] [Indexed: 11/16/2022] Open
Abstract
Background: Postexposure prophylaxis (PEP) with antiretroviral therapy (ART) and vaccination against hepatitis B virus (HBV) aides in preventing human immunodeficiency virus (HIV) infection and HBV, respectively, from accidental or occupational exposure. We assessed compliance to guidelines for HIV and HBV prevention after occupational exposure among hospital staff at a referral Kenyan hospital. Methods: We reviewed PEP registers for hospital staff reporting an occupational injury at a referral hospital in Western Kenya between January 2011 and December 2012. Proportions were used to summarize number of participants receiving the recommended services, Kaplan–Meier curves were used to describe time to ART initiation, and Chi-square statistics was used to describe the association between participant characteristics and PEP completion rates. P < 0.05 was considered statistically significant. Results: Majority of documented hospital staff (n = 52) were health workers (63%) and students (27%) and had high HIV risk exposures (97%). All had timely PEP initiation with 50% completing PEP. Completion rates did not vary by gender (P = 0.78), exposure type (P = 1.0), or department of exposure (P = 0.75). Retesting for HIV and negativity rates at months 1.5, 3, and 6 were 96%, 25%, and 17% and 100%, 100%, and 100%, respectively. At the time of exposure, 17% (9) of staff were HBV vaccinated and HBV status of sources was unknown; no intervention was provided for HBV prevention. Conclusions: Low rates of completion and follow-up negate intended benefits of PEP. Efforts should be directed to enforce universal precaution practices and completion of PEP. Low rates of HBV testing and vaccination illustrate the need for support for the implementation of HBV prevention guidelines.

Abstract
Background: Occupational exposure to bloodborne pathogen is a significant risk to health-care workers. In any teaching hospital apart from regular health-care workers and employees, there are significant population of students and trainee. It is important to assess the health-care worker in hospital which has maximum chances of exposure to these pathogens. The aim of this study is to determine the most susceptible job group for needlestick injury (NSI) reported in a newly established teaching medical institute in the Western part of Rajasthan, India. Methods: This is a retrospective analysis of data of NSI occurred during September 2014 to January 2017. Results: Sixty three NSIs were reported during the study. Nursing students were the most vulnerable group who reported maximum number of NSI. Among the nursing students, 72% were completely vaccinated against hepatitis B virus. Conclusions: Nursing students are at utmost risk for NSIs, the prevention of which requires regular training and education.

Abstract
Purpose Child sexual abuse and HIV are key health challenges in Kenya. In 2015, LVCT Health conducted a study aimed at assessing the quality of HIV-related services offered to child survivors of sexual violence in public health facilities. Materials and methods A qualitative data collection approach was utilized. Qualitative data were collected through in-depth interviews with 31 providers. Quantitative methods included a retrospective review of 164 records of child survivors of rape who had accessed services 6 months prior to the commencement of the study. SPSS Version 22 was used in the descriptive analysis of the medical records. Client exit interviews and observation data were analyzed using MS Excel. In-depth interviews were analyzed using a thematic analytical approach. Results Twenty-seven percent (n=164) survivors were documented to have received the first dose of postexposure prophylaxis (PEP). Providers did not conduct HIV pre- and posttest counseling for the survivors. There were no longitudinal follow-up mechanisms to ensure child survivors initiated on PEP adhered to the treatment plan. Less than 30% of survivors returned to the facility for PEP adherence counseling and follow-up HIV testing. Twenty providers cited capacity gaps in undertaking HIV risk assessment for child survivors. Limited availability of PEP is a barrier to HIV prevention, as most departments only offer services between 8 am and 5 pm. HIV tests were only available on weekdays before 5 pm. PEP being out of stock remains a barrier to HIV prevention. Conclusion Existing post-rape care services are not adequately structured to facilitate delivery of quality HIV-related services to child survivors. Health provider capacity in the management of children remains weak due to lack of skill-based training on the dynamics of responding to the needs of child survivors. There is a need for standard operating procedures and training modules on the prevention of HIV in the context of child sexual abuse.

Abstract
Gay, bisexual, and other men who have sex with men (MSM) have adapted their sexual practices over the course of the HIV/AIDS epidemic based on available data and knowledge about HIV. This study sought to identify and compare patterns in condom use among gay, bisexual, and other MSM who were tested for HIV at a community-based testing site in Montreal, Canada. Results showed that while study participants use condoms to a certain extent with HIV-positive partners and partners of unknown HIV status, they also make use of various other strategies such as adjusting to a partner's presumed or known HIV status and viral load, avoiding certain types of partners, taking PEP, and getting tested for HIV. These findings suggest that MSM who use condoms less systematically are not necessarily taking fewer precautions but may instead be combining or replacing condom use with other approaches to risk reduction.

Abstract
Statins, a class of cholesterol-lowering medications that inhibit 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase, are commonly administered to treat atherosclerotic cardiovascular disease. Statin use may expand considerably given its potential for treating an array of cholesterol-independent diseases. However, the lack of conclusive evidence supporting these emerging therapeutic uses of statins brings to the fore a number of unanswered questions including uncertainties regarding patient-to-patient variability in response to statins, the most appropriate statin to be used for the desired effect, and the efficacy of statins in treating cholesterol-independent diseases. In this review, the adverse effects, costs, and drug–drug and drug–food interactions associated with statin use are presented. Furthermore, we discuss the pleiotropic effects associated with statins with regard to the onset and progression of autoimmune and inflammatory diseases, cancer, neurodegenerative disorders, strokes, bacterial infections, and human immunodeficiency virus. Understanding these issues will improve the prognosis of patients who are administered statins and potentially expand our ability to treat a wide variety of diseases.

Abstract
INTRODUCTION Health Care Workers (HCWs) are at risk of occupational transmission of HIV, Hepatitis B and Hepatitis C, which can be minimized by following guidelines for standard precautions as well as taking Post Exposure Prophylaxis (PEP) measures. There are limited studies from India documenting details of PEP for HIV and Hepatitis B. AIM We aimed to study the efficacy, tolerance, details of PEP regimens used among HCWs exposed to HIV and Hepatitis B as well as vaccination status and (Anti-Hepatitis B Surface Antigen) anti-HBS Antibody Titre Level Among HCWs exposed Hepatitis B. STUDY DESIGN This retrospective observational study was done at a rural based tertiary care teaching centre of Western India. MATERIALS AND METHODS Hospital Infection Control Committee of our institute was maintaining a record of all reported incidences of HIV and Hepatitis B positive exposures since 2003. We analysed reported incidences of exposures to HIV and Hepatitis B positive source occurred during the period of January 2003 to December 2015. RESULTS Of the total 96 exposures, 48 were to HIV and 48 were to Hepatitis B. Of the 48 exposures to HIV, PEP was warranted in 39. Of 39 exposures, only 14 (35.9%) received PEP within two hours. Basic regimen was used in 22 and expanded in 17 exposures. Only 12 (31.6%) reported side effects to PEP. Zidovudine based regimen was less well tolerated. All side effects were reported by female HCWs only. Of the 48 exposed to Hepatitis B, 33 (68.6%) were completely vaccinated. Out of 33, titre result was not available for eight. Three (12.0%) of remaining 25 were having low titre (<10mIU/ml) of anti-HBS antibody. Five of six with incomplete vaccination status demonstrated anti HBS antibody titre > 100mIU/ml. Of the 48, in 17 (35.4%) incidences no action was required; 23 (47.9%) were managed with booster dose of Hepatitis B vaccine and eight (16.7%) with Hepatitis B immunoglobulin. No cases of sero-conversion was reported either for HIV or Hepatitis B from available data. CONCLUSION Inspite of high incidences of exposures to HIV or Hepatitis B positive source, good efficacy of PEP was observed with no sero-conversion. PEP for HIV was well tolerated; female HCWs were less tolerant. Study emphasized the need for creating awareness about timely reporting of incidence, achieving maximum vaccination against Hepatitis B for all HCWs and need for anti-HBS antibody titre.

Abstract
Objectives The care of exposed individuals to HIV remains a challenge regarding follow-up completion and HIV-testing of the partner. Identifying patients with risk of not fulfilling HIV-testing follow-up completion (FC), among patients demanding non-occupational post-exposure prophylaxis (nPEP), may improve clinical practice. Methods A retrospective chart review was conducted in a single French HIV-infection care center. FC predictors were assessed in a multivariate logistic regression model (Likelihood ratios test). Results Between 2009 and 2013, 646 sexual exposures to HIV were evaluated for nPEP, of which 507 effectively received nPEP (78%). FC rate was 30% (194/646). In the multivariate analysis, FC rates rose with age of exposed individuals (OR, 1.04 [0.25–4.28]; p<0.001) and decreased with the year of sexual exposure (OR, 0.74 [0.65–0.85]; p<0.001). FC was associated with sexual encounter with a sex worker (OR, 4.07 [0.98–16.82]; p<0.001) and nPEP use (OR, 2.69 [2.37–3.06]; p<0.001). nPEP early discontinuation was associated with decreased FC rates (OR, 0.18 [0.08–0.39]; p<0.001). No documented nPEP failure was identified. However, five Men who have Sex with Men (MSM) nPEP recipients for unprotected anal receptive intercourse subsequently seroconverted to HIV more than 6 months after nPEP. Seroconversion to HIV was associated with the lack of FC (p = 0.04) and multiple presentations for nPEP over the study period (p = 0.002). Conclusions We identified significant predictors of not fulfilling sequential HIV-testing. They appear to be linked with a self-perceived HIV risk, especially in young adults recently exposed. Enhanced counseling in targeted individuals with high risk behaviors and using smartphone and internet-based strategies may be interesting retention in care options.

Abstract
PURPOSE Non-occupational post-exposure prophylaxis (nPEP) is an underutilized biomedical option for HIV prevention. Few studies have assessed male couples' knowledge of and willingness to use nPEP. METHODS Cross-sectional dyadic data from 275 HIV-negative and 58 HIV-discordant male couples were used to describe HIV-negative, partnered men's awareness and willingness to use nPEP, and factors associated with their willingness to use nPEP. Data were analyzed with the use of multivariate multilevel modeling. RESULTS Less than a third of the men were aware of nPEP, yet 73% were very-to-extremely likely to use nPEP. Partnered men's willingness to use nPEP was positively associated with having an individual income less than $30,000 USD and serosorting within the relationship. Willingness to use nPEP was negatively associated with greater age difference between primary partners and with higher scores on measures of couples' investment in their relationship. CONCLUSION Efforts should be made to increase male couples' awareness of nPEP and how to access nPEP. Uptake of nPEP has the potential to help avert new HIV infections among male couples.

Abstract
Background There is limited evidence on the efficacy of post-exposure prophylaxis (PEP) for sexual exposures. We sought to determine the factors associated with adherence to treatment and describe the incidence of PEP failures in a Montreal clinic. Methods We prospectively assessed all patients consulting for PEP following sexual exposures from October 2000 to July 2014. Patients were followed at 4 and 16 weeks after starting PEP. Treatment adherence was determined by self-report at week 4. Multivariable logistic regression was used to estimate the factors predicting adherence to treatment. Results 3547 PEP consults were included. Patients were mainly male (92%), MSM (83%) and sought PEP for anal intercourse (72%). Seventy-eight percent (n = 2772) of patients received a prescription for PEP, consisting of Tenofovir/Emtracitabine (TVD) + Lopinavir/Ritonavir (LPV) in 74% of cases, followed by Zidovudine/Lamivudine (CBV) + LPV (10%) and TVD + Raltegravir (RAL) (8%). Seventy percent of patients were adherent to treatment. Compared to TVD+LPV, patients taking CBV+LPV were less likely to adhere to treatment (OR 0.58, 95% CI 0.44–0.75), while no difference was observed for patients taking TVD+RAL (OR 1.15, 95% CI 0.83–1.59). First-time PEP consults, older and male patients were also more adherent to treatment. Ten treated patients seroconverted (0.37%) during the study period, yet only 1 case can be attributed to PEP failure (failure rate = 0.04%). Conclusion PEP regimen was associated with treatment adherence. Patients were more likely to be adherent to TVD-based regimens. Ten patients seroconverted after taking PEP; however, only 1 case was a PEP failure as the remaining patients continued to engage in high-risk behavior during follow-up. One month PEP is an effective preventive measure to avoid HIV infection.

Abstract
Background Adequate knowledge and practices on post exposure prophylaxis (PEP) for HIV among health care providers are crucial for HIV prevention. However there is limited data on PEP knowledge and practice from developing countries where the burden of HIV infection continues to increase. We assessed the knowledge of clinical medical students on PEP, their practices in response to occupational exposure to HIV, as well as the determinants of good knowledge on PEP. Methods A cross-sectional study was conducted in November 2014 involving 154 consecutively recruited clinical medical students (4th-6th year undergraduates). Data were acquired using a structured questionnaire. Knowledge on PEP was assessed using a questionnaire comprising 25 questions and categorized as: good (20 or more correct answers), moderate (13–19 correct answers) and poor (12 or fewer correct answers). Results For the 154 students included (57.8 % being male), the mean age was 23.2 ± 2.4 years, and 89 % had heard about PEP for HIV. The majority of students had moderate (61.7 %) and poor (32.5 %) knowledge on PEP. Overall knowledge score increased with increasing level of studies (p < 0.05). Only 10 (6.5 %) had had previous training on PEP, most of whom were senior level students (p = 0.01). Fifty-four students (35.1 %) knew the appropriate duration of PEP and this awareness increased with level of studies (p = 0.001). Of the 81 (52.6 %) who reported occupational exposure to HIV in the past, only 4 (4.9 %) received PEP. Conclusions Overall, knowledge on PEP among clinical medical students in this setting was non-optimal with very low uptake PEP. Intensification of HIV curricula to involve PEP as well as continuous medical education programs and workshops are potential avenues to improve awareness in this vulnerable population.

Abstract
More information is needed about factors influencing real-life implementation and program impact of interventions effective in controlled study conditions. Ongoing national implementation of an evidence-based HIV prevention program targeting grade 6 students in The Bahamas offers the opportunity to examine patterns of implementation and relate them to student outcomes. Data were collected from 208 grade 6 teachers, 75 grade 7 teachers and 4411 grade 6 students followed over 2 years. Mixed-effects modeling analysis examined the association of teachers' patterns of implementation with student outcomes. High quality program implementation in grade 6 (high implementation dosage and fidelity) was significantly related to student outcomes six and 18 months post-intervention. Quality of implementation of the booster session in grade 7 was also significantly related to student outcomes in grade 7. Quality of delivery of the brief booster session a year after initial implementation is important in maintaining or resetting the student outcome trajectory.

Gachanja G. A rapid assessment of post-disclosure experiences of urban HIV-positive and HIV-negative school-aged children in Kenya. PeerJ 2015; 3:e956. [PMID: 26082868 PMCID: PMC4465943 DOI: 10.7717/peerj.956] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2014] [Accepted: 04/24/2015] [Indexed: 11/20/2022] Open
Abstract
There has been limited involvement of HIV-negative children in HIV disclosure studies; most studies conducted on the effects of disclosure on children have been with HIV-positive children and HIV-positive mother-child dyads. Seven HIV-positive and five HIV-negative children participated in a larger study conducted to understand the lived experiences of HIV-positive parents and their children during the disclosure process in Kenya. In this study, the experiences of these 12 children after receiving disclosure of their own and their parents' illnesses respectively are presented. Each child underwent an in-depth qualitative semi-structured digitally recorded interview. The recorded interviews were transcribed and loaded into NVivo8 for phenomenological data analysis. Five themes emerged from the data, indicating that HIV-positive and negative children appear to have differing post-disclosure experiences revolving around acceptance of illness, stigma and discrimination, medication consumption, sexual awareness, and use of coping mechanisms. Following disclosure, HIV-negative children accepted their parents' illnesses within a few hours to a few weeks; HIV-positive children took weeks to months to accept their own illnesses. HIV-negative children knew of high levels of stigma and discrimination within the community; HIV-positive children reported experiencing indirect incidences of stigma and discrimination. HIV-negative children wanted their parents to take their medications, stay healthy, and pay their school fees so they could have a better life in the future; HIV-positive children viewed medication consumption as an ordeal necessary to keep them healthy. HIV-negative children wanted their parents to speak to them about sexual-related matters; HIV-positive children had lingering questions about relationships, use of condoms, marriage, and childbearing options. All but one preadolescent HIV-positive child had self-identified a person to speak with for social support. When feeling overwhelmed by their circumstances, the children self-withdrew and performed positive activities (e.g., praying, watching TV, listening to the radio, singing, dancing) to help themselves feel better. Many HIV-affected families have a combination of HIV-positive and negative siblings within the household. Pending further studies conducted with larger sample sizes, the results of this study should assist healthcare professionals to better facilitate disclosure between HIV-positive parents and their children of mixed HIV statuses.
