RÉSUMÉ

INTRODUCTION: Social network-based testing approaches (SNAs) encourage individuals ("test promoters") to motivate sexual partners and/or those in their social networks to test for HIV. We conducted a systematic review to examine the effectiveness, acceptability and cost-effectiveness of SNA. METHODS: We searched five databases from January 2010 to May 2023, and included studies that compared SNA with non-SNA. We used random-effects meta-analysis to combine effect estimates. Certainty was assessed using the GRADE approach. RESULTS: We identified 47 studies. SNA may increase uptake of HIV testing compared to non-SNA (RR 2.04, 95% CI: 1.06-3.95, Low certainty). The proportion of first-time testers was probably higher among partners or social contacts of test promoters using SNA compared to non-SNA (RR 1.49, 95% CI: 1.22-1.81, Moderate certainty). The proportion of people who tested positive for HIV may be higher among partners or social contacts of test promoters using SNA compared to non-SNA (RR 1.84, 95% CI: 1.01-3.35, Low certainty). There were no reports of any adverse events or harms associated with SNA. Based on six cost-effectiveness studies, SNA was generally cheaper per person tested and per person diagnosed compared to non-SNA. Based on 23 qualitative studies, SNA is likely to be acceptable to a variety of populations. DISCUSSION: Our review collated evidence for SNA to HIV testing covering the key populations and the general population who may benefit from HIV testing. We summarized evidence for the effectiveness, acceptability and cost-effectiveness of different models of SNA. While we did not identify an ideal model of SNA that could be immediately scaled up, for each setting and population targeted, we recommend various implementation considerations as our meta-analysis showed the effectiveness might differ due to factors which include the testing modality (i.e. use of HIV self-testing), type of test promoters, long or short duration of recruitment and use of financial incentives. CONCLUSIONS: Social network-based approaches may enhance HIV testing uptake, increase the proportion of first-time testers and those testing positive for HIV. Heterogeneity among studies highlights the need for context-specific adaptations, but the overall positive impact of SNA on HIV testing outcomes could support its integration into existing HIV testing services.

RÉSUMÉ

The unique case study presented here explores an exceptionally rare occurrence in an HIV-positive female-synchronous diagnoses of anal squamous cell carcinoma and diffuse large B cell lymphoma (DLBCL) of the stomach. With limited existing literature on such clinical scenarios, this case serves as an unprecedented insight into the complexities of managing such synchronous malignancies in HIV-positive patients. The article also examines the heightened risk of specific cancer types in individuals living with HIV compared to those without the virus, focusing on AIDS-defining cancers such as Kaposi sarcoma, various lymphomas (including Burkitt lymphoma, immunoblastic lymphoma, and primary central nervous system lymphoma), and invasive cervical cancer. Additionally, it highlights an increased incidence and severity of other cancers amongst HIV-positive individuals, including Hodgkin lymphoma, anal cancer, testicular cancer, melanoma, various skin and superficial eye cancers, and leiomyosarcoma. The article discusses the challenges in the treatment plan, the impact of HIV status on the patient's condition, and the evolving landscape of cancer risk in people living with HIV. Despite significant progress in HIV care, cancer remains a paramount health concern for this population, necessitating tailored approaches and further research to ensure improved outcomes for individuals facing this dual challenge. The case highlights the need for greater inclusivity of PLWH in cancer clinical trials and reinforces the importance of equitable cancer care for this unique patient demographic.

RÉSUMÉ

BACKGROUND: HIV self-testing (HIVST) offers an innovative and promising approach to increasing HIV testing among Black men in the United States, a population disproportionately affected by HIV. However, engaging Black men in traditional HIV prevention programs has been challenging due to stigma, medical mistrust, and limited access to preventive health services. This formative qualitative study aimed to explore the potential of utilizing barbershops as an example of a nontraditional healthcare venue to promote and distribute HIVST. METHODS: Four virtual focus group discussions (FGDs) consisting of 19 participants in North Carolina were conducted with Black men, including barbershop business owners, barbers, and their customers, to assess perceptions of HIVST and the acceptability of partnering with barbershop businesses to promote HIVST. FGDs were digitally recorded, transcribed, and analyzed using a deductive coding approach to thematic analysis. RESULTS: Participants reported that the trusting relationship between barbers and their customers, which may not exist between Black men and health care providers, is a facilitator of collaborating with barbershop businesses to reach Black men for HIVST distribution. Participants recommended providing education for barbers on the use of HIVST, as well as how to inform self-testers about linkage to care following HIVST to build the credibility of the barbers in delivering the intervention. Participants also raised the issue of the cost of HIVST to barbershop customers as a potential barrier to implementation, as well as the possibility that the implementation of such interventions could be seen as out of place in a barbershop business venue. Participants also expressed a strong belief that compensation to barbershops and their employees should accompany any intervention. CONCLUSION: These findings suggest that barbershop business venues may provide an appropriate venue for HIVST promotion and distribution, though factors like cost, training, and incentivization of implementers are necessary to consider in implementation planning. Furthermore, partnerships between public health actors and the business community must be built on equitable engagement to ensure the long-term viability of these critical initiatives.

RÉSUMÉ

With advancements in antiretroviral therapy (ART), the average lifespan of people with human immunodeficiency virus (HIV) is increasing, as is the number of older adults with HIV. Accordingly, the number of patients with HIV who undergo surgery or require critical care for various reasons is increasing. Since the prognosis of people with HIV depends on the continuous and effective maintenance of ART, there is a need to consider effectively maintaining ART in people with HIV in these conditions. This case involved a 55-year-old patient with well-controlled HIV who received ART and presented to the emergency room with acute abdominal pain. He was diagnosed with extensive bowel infarction and panperitonitis and received critical care in the intensive care unit, including mechanical ventilation and continuous renal replacement therapy. The patient was administered enteral nutrition via a nasogastric tube. The patient subsequently underwent extensive small bowel resection and developed short bowel syndrome. The patient maintained ART during that period. A literature review related to the use of ART under these conditions is included in this study. This case was discussed at the [Exploring Difficult Cases in HIV Clinics] of the Korean Society for AIDS Conference held in 2023.

RÉSUMÉ

Background: There are limited data on the effectiveness of differentiated service delivery (DSD) for HIV care during sociopolitical turmoil. We assessed outcomes with a DSD model of care that includes patient choice between community-based antiretroviral therapy (ART) centres, home-based ART dispensing, or facility-based care at GHESKIO clinic during a period of severe civil unrest in Port-au-Prince, Haiti. Methods: This retrospective analysis included data on patients with at least one HIV visit at GHESKIO between May 1, 2019, and December 31, 2021. Multivariable logistic regression models were used to assess predictors of attending ≥1 community visit during the study period, and failure to attend timely visits. HIV-1 RNA test results were reported among patients who had been ART for ≥3 months at last visit. Findings: Of the 18,625 patients included in the analysis, 9659 (51.9%) attended at least one community visit. The proportion of community visits ranged from 0.3% (2019) to 44.1% (2021). Predictors of ≥1 community visit included male sex (aOR: 1.13; 95% CI: 1.06, 1.20), secondary education (aOR: 1.07; 95% CI: 1.01, 1.14), income > $USD 1.00/day (aOR: 1.24; 95% CI: 1.14, 1.35), longer duration on ART (aOR: 1.08 per additional year; 95% CI: 1.07, 1.09), and residence in Carrefour/Gressier (p < 0.0001 in comparisons with all other zones). Younger age and shorter time on ART were associated with late visits and loss to follow-up. Among 12,586 patients with an on-time final visit who had been on ART for ≥3 months, 11,131 (88.4%) received a viral load test and 9639 (86.6%) had HIV-1 RNA < 1000 copies/mL. Interpretation: The socio-political situation in Haiti has presented extraordinary challenges to the health care system, but retention and viral suppression rates remain high with a model of community-based HIV care. Additional interventions are needed to improve outcomes for younger patients, and those with shorter time on ART. Funding: No funding.

RÉSUMÉ

Primary care workplaces where occupational exposure to blood and body fluids may occur should have policies and procedures in place to manage such incidents. All healthcare workers should be immunised against hepatitis B and ideally should have documentation of their antibody response to vaccination. Knowledge of hepatitis B immune status helps streamline the response to any exposure. Most occupational exposures carry a low risk of transmission of bloodborne viruses, and management can often be undertaken in general practice. Urgent risk assessment and management is crucial. If postexposure prophylaxis for hepatitis B or HIV is required, the earlier it is given, the more likely it is to be effective. Two-drug HIV postexposure prophylaxis is now more accessible because generic formulations of the drug combination are available, and general practitioners can prescribe this on a private prescription.

RÉSUMÉ

Background: HIV testing remains an entry point into HIV care and treatment services. In 2007, Nigeria adopted and implemented a two-test rapid HIV testing algorithm of three HIV rapid test kits, following the sequence: Alere Determine (first test), UnigoldTM (second test), and STAT-PAK® as the tie-breaker. Sub-analysis of the 2018 Nigeria HIV/AIDS Indicator and Impact Survey data showed significant discordance between the first and second tests, necessitating an evaluation of the algorithm. This manuscript highlights lessons learnt from that evaluation. Intervention: A two-phased evaluation method was employed, including abstraction and analysis of retrospective HIV testing data from January 2017 to December 2019 from 24 selected sites supported by the United States President's Emergency Plan for AIDS Relief programme. A prospective evaluation of HIV testing was done among 2895 consecutively enrolled and consented adults, aged 15-64 years, accessing HIV testing services from three selected sites per state across the six geopolitical zones of Nigeria between July 2020 and September 2020. The prospective evaluation was performed both in the field and at the National Reference Laboratory under controlled laboratory conditions. Stakeholder engagements, strategic selection and training of study personnel, and integrated supportive supervision were employed to assure the quality of evaluation procedures and outcomes. Lessons learnt: The algorithm showed higher sensitivity and specificity in the National Reference Laboratory compared with the field. The approaches to quality assurance were integral to the high-quality study outcomes. Recommendations: We recommend comparison of testing algorithms under evaluation against a gold standard. What this study adds: This study provides context-specific considerations in using World Health Organization recommendations to evaluate the Nigerian national HIV rapid testing algorithm.

RÉSUMÉ

Background: The roll-out of antiretroviral medicines has improved life expectancy in people living with HIV (PLHIV). This has resulted in more patients being hospitalised for non-communicable diseases, increasing risk for medication errors (MEs). Pharmacists, through medication reconciliation, may identify and reduce MEs in this population. Objectives: To describe the importance of a pharmacist's involvement in identifying and quantifying types of MEs. Method: A quantitative, prospective observational study was conducted over 14 weeks. A pharmacist reviewed HIV-positive, hospitalised patients' files, using a data collection instrument, to determine the prevalence of MEs in PLHIV. The study pharmacist recommended appropriate actions to the prescriber to resolve MEs and documented resolution of the MEs. Results: The study population of n = 180 patient files were reviewed 453 times, identifying 466 MEs. Medication errors included incorrect medication reconciliation from history (19; 4.1%), prescription omission (17; 3.7%), duplication of therapy (10; 2.2%), missed doses (265; 57.1%), incorrect dosing (103; 22.2%), incorrect administration frequency (2; 0.4%), incorrect duration of therapy (15; 3.2%) and drug-drug interactions (18; 3.9%). More than half (58.2%) of the MEs were resolved in less than 24 h, with involvement of the pharmacist. Conclusion: This study demonstrates the magnitude of MEs experienced in hospitalised PLHIV and highlights the role clinical pharmacists play in identifying and resolving MEs to improve patient outcomes.

RÉSUMÉ

Background: Dual HIV/syphilis testing may be an acceptable intervention to identify men with sexually transmitted infections (STIs) and at risk of HIV acquisition. Objectives: We sought to determine the acceptability, and performance of dual HIV/syphilis testing among men attending voluntary medical male circumcision (VMMC) services at six public sector facilities in Gauteng. Method: This was a cross-sectional study at VMMC facilities. Men ≥ 18 years were enrolled. The men had (1) a questionnaire administered, (2) on-site dual HIV/syphilis testing with First Response HIV1+2/Syphilis Combo Card Test by routine lay counsellors, and (3) a blood specimen collected for centralised laboratory testing for HIV and syphilis serology. We evaluated pre-test and post-test acceptability and performance compared to serological testing. Results: Of the 679 men analysed (median age 32.1 years), 96.7% of HIV-negative men preferred testing for HIV and syphilis simultaneously. Of the 675 men tested for syphilis, 28 (4.7%) tested positive (past or recent). In the laboratory, 43/609 (7.1%) had syphilis infection detected, with 9/609 (1.5%) having recent syphilis. There was sub-optimal sensitivity for HIV detection (90.9%; 95% confidence interval [CI]: 88.5% - 93.3%), and for past/recent syphilis (55.8%; 95% CI: 51.9% - 59.8%), improving to 88.9% (95% CI: 86.4% - 91.4%) for recent syphilis. Specificities were > 99% for HIV and syphilis (past or recent). Post-test acceptability was 96.6% and willingness to pay for future testing was 86.1%. Conclusion: Dual HIV/syphilis testing was acceptable but had sub-optimal sensitivity for HIV and syphilis. Syphilis detection was adequate for recent infection.

RÉSUMÉ

Background: Anaemia is associated with reduced quality of life and increased mortality risk among people living with HIV (PLHIV). Although antiretroviral therapy (ART) reduces the prevalence of anaemia, some patients remain at risk after commencing ART. Objectives: We estimated the incidence of anaemia after ART commencement and identified associated risk factors. Method: We analysed outpatient records at Newlands Clinic, Harare, Zimbabwe. Patients (≥ 5 years old) who were commenced on ART between January 2016 and December 2020 were included and were followed up for up to 2 years. Patients with anaemia at ART commencement and women who were pregnant at any time during follow-up were excluded. Cox proportional hazards regression was used to assess independent risk factors for anaemia. Results: During the study, 1110 patients ≥ 5 years old were commenced on ART with a prevalence of anaemia of 40.0%. Five hundred and twenty-nine patients met the inclusion criteria and were followed up for 823.7 person-years. The median age was 36.1 years and 290 (58.4%) were female. The incidence rate of anaemia after ART commencement was 176.1 per 1000 person-years (95% confidence interval [CI]: 149.6-207.2). Females (aHR: 2.09; 95% CI: 1.46-3.00, P < 0.001), zidovudine use (aHR: 3.50 96% CI: 2.14-5.71, P < 0.001), age 5-12 years or > 50 years, and the presence of World Health Organization stage III/IV disease (aHR: 2.19; 95% CI: 1.14-5.71, P = 0.019) had higher odds of developing anaemia. Conclusion: The incidence of anaemia after ART commencement was high. Female sex, zidovudine use, age and the presence of stage III/IV disease were independent risk factors for anaemia. Clinicians should screen PLHIV on ART regularly for anaemia.

RÉSUMÉ

Background: Long-acting cabotegravir (CAB-LA) is highly effective for HIV prevention, but delayed HIV diagnoses and integrase strand transfer inhibitor (INSTI) resistance were observed in trials. We report the first case in routine clinical care of HIV infection on CAB-LA with INSTI resistance. Methods: The SeroPrEP study enrolls individuals in the United States who acquire HIV on pre-exposure prophylaxis modalities to assess diagnostics, antiretroviral (ARV) drug levels, resistance, and treatment outcomes. Resistance mutations in full-length HIV-1 integrase were identified by single-genome sequencing (SGS). Cabotegravir concentrations in plasma and hair segments were measured by liquid chromatography-tandem mass spectrometry. Results: A 23-year-old gender-nonbinary person, male at birth, restarted CAB-LA 6 months after discontinuation due to losing insurance. Prior to restart, HIV-1 RNA was not detected, but 20 days elapsed before CAB-LA injection. After the second CAB-LA injection, HIV antigen/antibody returned reactive (HIV-1 RNA 451 copies/mL). SGS of plasma HIV-1 RNA identified INSTI mutation Q148R in 2/24 sequences 2 days postdiagnosis; commercial genotype failed amplification. Cabotegravir hair concentration was 0.190 ng/mg 2 weeks prediagnosis; plasma cabotegravir was high (3.37 µg/mL; ∼20× PA-IC90) 14 days postdiagnosis. Viral suppression was maintained for 6 months on darunavir/cobicistat/emtricitabine/tenofovir alafenamide, then switched to doravirine + emtricitabine/tenofovir alafenamide due to nausea. Conclusions: In this first case of HIV infection on CAB-LA with INSTI resistance in routine care, cabotegravir resistance was detected only with a sensitive research assay. Accelerated pathways to minimize time between HIV testing and CAB-LA initiation are needed to optimize acute HIV detection and mitigate resistance risk. Sustained product access regardless of insurance is imperative to reduce HIV infections on CAB-LA.

RÉSUMÉ

Background: The human immunodeficiency virus (HIV) epidemic in South Africa is among the worst in the world; in 2017, 38% of new infections were among young people aged 15-24 years. Estimates for HIV infection in 2020 worldwide indicate that there will be 1.5 million new cases, 10.2 million untreated cases (out of 37.7 million), and 680 000 deaths from acquired immunodeficiency syndrome (AIDS). Despite a 46% decline in new HIV infections among adolescents and youth over the previous 10 years, two of the seven new HIV infections in 2019 occurred in people between the ages of 15 and 24. HIV prevalence among young people has remained unchanged since 2008. This consistent pattern among people under 30 years of age indicates a failure in HIV prevention. Aim: The study aimed to explore HIV and sexual risk behaviours by 18-25-year-old youth at Nyandeni Municipality in the Eastern Cape province. Setting: The investigation was conducted Nyandeni Municipality in the Eastern Cape province. Methods: Qualitative approach was used to explore, describe and investigate the knowledge and attitudes about HIV among the 18-25 years old youth. Results: The findings are based on three themes namely, knowledge and attitudes about HIV and AIDS in youth, sexual risk behaviour among youth, and HIV prevention strategies. Conclusion: This exploratory investigation confirms that the participants' knowledge is limited by showing that most of them knew very little about HIV and AIDS infection and prevention. Ongoing educational initiatives are required. Contribution: Youth experience high HIV incidence because of their knowledge gaps.

RÉSUMÉ

Pulmonary tuberculosis (PTB), human immunodeficiency virus (HIV), and leprosy are of public health importance, as all three diseases are communicable and contribute to disease burden in society. Co-infection with these three entities is extremely rare but leads to significant mortality and morbidity. We report a case that highlights the diagnostic challenges and therapeutic management of a patient who was diagnosed with pure neuritic leprosy on multibacillary-multidrug therapy (MB-MDT) and subsequently co-diagnosed with PTB and HIV. The patient was started on anti-tubercular therapy and anti-retroviral therapy for treatment under India's national health programs, which play a major role in treating those of low socioeconomic status. The optimization of these therapeutic drugs is quite challenging during treatment due to potential drug interactions and toxicities. High clinical suspicion is required to rule out PTB before initiating rifampicin-containing MB-MDT, which can lead to rifampicin-resistant TB and screening for HIV. As there is a social stigma associated with these patients, they require good psychological support during and after treatment.

RÉSUMÉ

Background and Aims: A growing number of acquired immunodeficiency syndrome (AIDS) patients suffer from opportunistic intestinal coccidian infections. Instead of human immuno deficiency virus (HIV) infection itself, opportunistic infections like intestinal coccidian parasites cause death of over 80% AIDS patients. Factors like exposed drinking water sources and poverty aid the prevalence of opportunistic intestinal coccidian parasitic infections in HIV/AIDS patients. The goal of this study was to determine the prevalence of intestinal coccidian parasites and associated factors in HIV/AIDS patients. Methods: A health facility based cross sectional study was conducted from 140 HIV/AIDS patients attending ART clinic in Debre Tabor Comprehensive Specialized Hospital, Northwest Ethiopia from September to December 2023. The sociodemographic characteristics were collected through face-to-face interviews. Stool samples were processed with Modified Acid Fast staining technique. Statistical Package for Social Sciences software version 20 was used to analyze the data. Logistic regression was used to assess factors associated with dependent variable and p < 0.05 was considered significantly associated. Results: The total prevalence of opportunistic intestinal coccidian parasites (OICPs) in HIV/AIDS patients was 16.4% (23/140). Drinking surface water [p = 0.015, COR = 3.4] compared to tape water, drinking alcohol [p = 0.001, COR = 18] compared to not drinking alcohol, diarrhea [p = 0.005, COR = 1] compared to non-diarrheic, drug dropout [p = 0.01, COR = 11] compared to regular drug intake and low CD4 count [p = 0.042, COR = 9] compared to CD4 > 500/µL showed significant association with increased prevalence of OICPs in HIV/AIDS patients. Conclusions: OICPs are still the common causes of morbidity and mortality in HIV/AIDS patients. Surface water consumption, alcoholism, interruption of treatment drugs, diarrhea, and reduced CD4+ T-cells significantly contribute to acquisition and prevalence of OICPs in HIV/AIDS patients. Routine screening of OICPs with sensitive diagnostic techniques in HIV/AIDS patients regardless of symptoms is crucial and has to be practiced in health settings.

RÉSUMÉ

In a tragically ironic twist, antiretroviral therapy (ART) that promised an end to AIDS ushered in a syndemic of viral cancers, transforming hope to despair. In this article we draw from the illness narratives of HIV positive women attending a cervical cancer screening clinic in Johannesburg, South Africa, and chart their pathways from HIV to cancer, and their quest for treatment. Our interlocutors described protracted struggles to access surgical procedures to prevent the onset of cervical cancer. Dealt a double blow of HIV and cervical cancer, women's narratives reveal the intersections of exposure to pathogens and the precarity of hope.

RÉSUMÉ

BACKGROUND: The HVTN 705 Imbokodo trial of 2636 people without HIV and assigned female sex at birth, conducted in southern Africa, evaluated a heterologous HIV-1 vaccine regimen: mosaic adenovirus 26-based vaccine (Ad26.Mos4.HIV) at Months 0, 3, 6, 12 and alum-adjuvanted clade C gp140 at Months 6, 12. Per-protocol vaccine efficacy (VE) against HIV-1 diagnosis from seven to 24 months was 14.1% (95% CI: -22.0% to 39.5%). Immune correlates analysis was performed for markers selected based on prior evidence in efficacy trials and/or nonhuman primate models. METHODS: Humoral and cellular immune response markers at Month 7 were evaluated as immune correlates of risk and of protection in a breakthrough case-control cohort (n = 52 cases, 246 non-cases). Primary markers were IgG binding to vaccine-strain gp140, IgG3 binding to diverse Env antigens (IgG3 Env breadth), IgG3 binding to diverse V1V2 antigens (IgG3 V1V2 breadth), antibody-dependent phagocytosis against the vaccine-strain gp140, Env-specific CD4+ and CD8+ T-cell responses, and multi-epitope functions. FINDINGS: No immune markers were statistically significant correlates of risk. IgG3 V1V2 breadth trended toward an inverse association: hazard ratio 0.70 (95% CI: 0.36 to 1.35; p = 0.29) per 10-fold increase and 0.51 (95% CI: 0.21 to 1.24; p = 0.14) in a Cox model with all primary markers. The VE estimate was 11.8% (95% CI: -17.9% to 34.0%) at all IgG3 V1V2 breadth values below 667 weighted geometric mean net MFI; just above this value, the VE estimate sharply increased to 62.6% (95% CI: -17.9% to 89.6%), and further increased to 80.9% (95% CI: -17.9% to 99.5%) at 1471 MFI, the 95th percentile of the marker distribution. Mediation analysis yielded a VE of 35.7% (95% CI: 15.0% to 51.3%) attributable to the vaccine's impact on this marker. INTERPRETATION: The trend in association of greater IgG3 V1V2 antibody breadth with lower likelihood of HIV acquisition is consistent with the identification of antibodies against V1V2 as immune correlates in three other HIV vaccine efficacy trials and suggests that a greater emphasis should be placed on studying this region in the HIV-1 envelope as a vaccine immunogen.

RÉSUMÉ

Behavioral health conditions are disproportionately experienced by people living with Human immunodeficiency virus (HIV), including young Black gay, bisexual, and other men who have sex with men (GBMSM). Left unaddressed, these symptoms can adversely impact HIV care outcomes. Improving the integration of behavioral health and HIV care services has been proposed as a strategy to address this challenge. To conduct a pre-implementation study exploring barriers and facilitators to improving HIV and behavioral health care integration at two HIV clinics in Atlanta, Georgia. We conducted a mixed-methods study guided by the Consolidated Framework for Implementation Research (CFIR). Sixty (60) HIV care providers, behavioral health care providers, and social service providers participated in cross-sectional surveys, and a subset of survey participants (15) also participated in a qualitative in-depth interview to explore CFIR constructs in greater depth. We focused on Intervention Characteristics, Outer Setting, and Inner Setting as the most relevant CFIR domains. Within each of these domains, we identified both facilitators and barriers to improving HIV and behavioral care integration in the two clinics. Participants agreed that enhancing integration would provide a relative advantage over current practice, would address young Black GBMSM and other patient needs, and would be compatible with the organizational mission. However, they also expressed concerns about complexity, resource availability, and priority relative to other clinic initiatives. Participants were enthusiastic about improving care integration but also invoked practical challenges to translating this idea into practice. Future research should test specific implementation strategies and their potential effectiveness for improving the integration of behavioral health and HIV care, as a strategy for improving well-being among young Black GBMSM and other people living with HIV.


People living with Human immunodeficiency virus (HIV), including young Black gay, bisexual, and other men who have sex with men, often experience challenges related to behavioral health. We did a study to explore barriers and facilitators to improving the integration of behavioral health and HIV services at two HIV clinics in Atlanta, Georgia. Our study included interviews and surveys with sixty care providers. Participants shared that improving care integration was a good idea and would address patients' needs. However, they also expressed concerns about challenges that might get in the way of integrating care effectively. Future research should test different ways of improving care integration in these types of settings.

RÉSUMÉ

OBJECTIVES: DREAM-01 was an open label, dose-escalation and variable osmolarity study to identify a tenofovir HIV-prevention douche/enema that could achieve protective colon tissue cell concentrations and high acceptability. To assess impact on sexual enjoyment, iso-osmolar and hypo-osmolar placebo douches were provided for at-home use before receptive anal sex (RAS). METHODS: Eighteen HIV-uninfected men who have RAS were administered three tenofovir douches at the research clinic: Product A, an iso-osmolar dose; Product B, an iso-osmolar escalation dose; and Product C, a hypo-osmolar escalation dose. Following Products A and C, participants were given a saline douche of matching osmolarity to use at home before RAS. Participants reported acceptability via a computer-assisted self-interview and in-depth interview in this mixed-methods study. RESULTS: All three products were rated acceptable by 17 (95%) of the participants. A majority (94%) would be likely or very likely to use any of the three products before RAS. Of those who used the saline douches before RAS and then rated their sexual enjoyment, most reported that their sexual enjoyment was not affected. Interview data revealed that participants found the product easy to incorporate into their regular routine, but would prefer to use more liquid for cleansing. CONCLUSIONS: These findings indicate that the hypo-osmolar Product C, which also provides the most rapid delivery of tenofovir for HIV prevention, is acceptable for future safety trials and that our sample reports high likelihood of using a rectal microbicide douche for HIV prevention. Our findings support continued pursuit of a tenofovir rectal microbicide douche. TRIAL REGISTRATION NUMBER: NCT02750540.

RÉSUMÉ

Cryptococcal meningitis (CM) is a well-recognized fungal infection, with substantial mortality in HIV-infected individuals. However, the incidence, risk factors, and outcomes in non-HIV adults remain poorly understood. This study aims to investigate the characteristics and prognostic indicators of CM in non-HIV adult patients, integrating a novel predictive model to guide clinical decision-making. A retrospective cohort of 64 non-HIV adult CM patients, including 51 patients from previous studies and 13 from the First Hospital of Shanxi Medical University, was analyzed. We assessed demographic features, underlying diseases, intracranial pressure, cerebrospinal fluid characteristics, and brain imaging. Using the LASSO method, and multivariate logistic regression, we identified significant variables and constructed a Nomogram prediction model. The model's calibration, discrimination, and clinical value were evaluated using the Bootstrap method, calibration curve, C index, goodness-of-fit test, ROC analysis, and DCA analysis. Age, brain imaging showing parenchymal involvement, meningeal and ventricular involvement, and previous use of immunosuppressive agents were identified as significant variables. The Nomogram prediction model displayed satisfactory performance with an AIC value of 72.326, C index of 0.723 (0.592-0.854), and AUC of 0.723, Goodness-of-fit test P=0.995. This study summarizes the clinical and imaging features of adult non-HIV CM, and introduces a tailored Nomogram prediction model to aid in patient management. The identification of predictive factors and the development of the nomogram enhance our understanding and capacity to treat this patient population. The insights derived have potential clinical implications, contributing to personalized care and improved patient outcomes.


Cryptococcal meningitis (CM) is a serious fungal infection that can affect the brain and spinal cord. It is well known to occur in people with HIV, but it can also affect those without HIV, although this is less common. This study focuses on understanding how CM affects non-HIV patients, which is not as well understood as its effects on HIV patients. We analyzed data from 64 non-HIV patients with CM to identify factors that might influence their recovery or lead to poor outcomes, such as severe disability or death. Using advanced statistical methods, we developed a predictive tool called a nomogram. This tool helps doctors estimate the likelihood of a poor outcome in non-HIV CM patients based on specific factors like age, brain imaging results, and the use of certain medications. Our findings suggest that older patients and those with specific brain imaging abnormalities may be at higher risk. On the other hand, patients who have previously used immunosuppressive drugs might have a better prognosis, which is a surprising and new insight. This research is important because it provides new knowledge that could help doctors better manage CM in non-HIV patients, leading to more personalized and effective treatments. The predictive tool we developed could be used in hospitals to improve decision-making and patient care, ultimately improving outcomes for those suffering from this serious condition.
