ABSTRACT

Background: Immune reconstitution following the initiation of combination antiretroviral therapy (cART) significantly impacts the prognosis of individuals infected with human immunodeficiency virus (HIV). Our previous studies have indicated that the baseline CD4+ T cells count and percentage before cART initiation are predictors of immune recovery in TB-negative children infected with HIV, with TB co-infection potentially causing a delay in immune recovery. However, it remains unclear whether these predictors consistently impact immune reconstitution during long-term intensive cART treatment in TB-negative/positive children infected with HIV. Results: We confirmed that the baseline CD4+ T cell count is a significant predictor of immune recovery following long-term intensive cART treatment among children aged 5 to 18 years. Children with lower CD4+ T cell count prior cART initiation did not show substantial immunological recovery during the follow-up period. Interestingly, children who were co-infected with TB and had higher baseline CD4+ T cell count eventually achieved good immunological recovery comparable to the TB-negative HIV-infected children. Hence, the baseline CD4+ T cell count at the onset of treatment serves as a reliable predictor of immunological reconstitution in HIV-infected children with or without TB co-infection. Taken together, this follow-up study validates our previous findings and further establishes that initiating cART early alongside early HIV testing can help prevent the diminished CD4+ T cell count associated with inadequate immunological reconstitution.

ABSTRACT

HIV-associated changes in intestinal microbiota are believed to be important drivers of disease progression. However, the majority of studies have focused on populations in high-income countries rather than in developing regions where HIV burden is greatest. To better understand the impact of HIV on fecal microbiota globally, we compare the fecal microbial community of individuals in the U.S., Uganda, and Botswana. We identify significant bacterial taxa alterations with both treated and untreated HIV infection with a high degree of uniqueness in each cohort. HIV-associated taxa alterations are also significantly different between populations that report men who have sex with men (MSM) behavior and non-MSM populations. Additionally, while we find that HIV infection is consistently associated with higher soluble markers of immune activation, most specific bacterial taxa associated with these markers in each region are not shared and none are shared across all three geographic locations in our study. Our findings demonstrate that HIV-associated changes in fecal microbiota are overall distinct among geographical locations and sexual behavior groups, although a small number of taxa shared between pairs of geographic locations warrant further investigation, highlighting the importance of considering host context to fully assess the impact of the gut microbiome on human health and disease.

ABSTRACT

The significance of Epstein-Barr virus (EBV) detection in the cerebrospinal spinal fluid (CSF) in people living with HIV (PLWH) is not entirely understood. The detection of EBV DNA may represent active central nervous system (CNS) infection, reactivation in the setting of another CNS pathogen or due to impaired immunity, or detection of quiescent virus. We screened 470 adult PLWH in Zambia with neurological symptoms for the presence of EBV DNA in the CSF. We performed quantitative EBV PCR on the CSF and blood. We then performed quantitative EBV DNA PCR on the blood of controls with documented HIV viral suppression without CNS symptoms. The prevalence of EBV DNA in the CSF of patients with CNS symptoms was 28.9% (136/470). EBV DNA positivity was associated with younger age, shorter duration of HIV diagnosis, lower CSF glucose levels, higher CSF protein and white blood cell levels, and a positive CSF Mycobacterium tuberculosis result. The median EBV DNA load was 8000 cps/mL in both the CSF and blood with a range of 2000-2,753,000 cps/mL in the CSF and 1000 to 1,871,000 cps/mL in the blood. Molecular screening of CSF for other possible causes of infection identified Mycobacterium tuberculosis in 30.1% and cytomegalovirus (CMV) in 10.5% of samples. EBV DNA load in the blood and CSF was not associated with mortality. Our results suggest that even though EBV DNA was commonly detected in the CSF of our population, it appears to have limited clinical significance regardless of EBV DNA load.

ABSTRACT

This study explored the factors associated with Black women's confidence in their ability to engage male sexual partners in discussions about PrEP. Communication about PrEP with male partners is an important, yet minimally explored, outcome in PrEP research among Black women in heterosexual partnerships. Among 315 respondents, results show significant differences in anticipated stigma and interest in PrEP between a binary outcome variable being confident and not-confident discussing PrEP with sexual partners. Further, factors such as employment, worrying about HIV infection, interest in taking oral PrEP, subjective norms, injunctive norms, and descriptive norms were associated with Black women's higher odds of confidence in their ability to engage sexual partners about PrEP. Conversely, PrEP disapproval and stigma resulted in lower odds of Black women's confidence in their ability to engage sexual partners about PrEP. Results indicate the need for continued investigation of confidence and, relatedly, communication about PrEP among heterosexual couples and communitylevel interventions normalizing PrEP discussions and uptake.

ABSTRACT

Preexposure prophylaxis (PrEP) for HIV prevention uptake remains low among Black cisgender women in the United States, despite their disproportionate HIV burden. This study aimed to examine factors associated with Black women's comfort discussing PrEP with healthcare providers and its link to their interest in PrEP use. A cross-sectional survey was conducted with a national sample of 315 Black cisgender women. Descriptive statistics and logistic regression models were utilized for data analysis. The results showed that 79% of Black women felt comfortable discussing PrEP with their healthcare provider. Age, recent healthcare provider visit, interest in PrEP, and positive social norms were associated with increased odds of comfort in discussing PrEP, while anticipated PrEP disapproval and stigma were associated with decreased odds. Older age was related to greater comfort, potentially due to increased familiarity and self-efficacy in discussing sexual health. Recent healthcare utilization indicated positive provider relationships, facilitating discussions about sexual health. Anticipating support from social networks positively influenced comfort levels. Conversely, PrEP-related stigma and anticipated disapproval were barriers to comfort. These findings highlight the importance of provider-patient communication and social support in facilitating PrEP engagement among Black cisgender women. Interventions should consider age-appropriate strategies and address structural and provider biases to improve PrEP discussions and promote HIV prevention.

ABSTRACT

BACKGROUND: The Centers for AIDS Research Diversity, Equity, and Inclusion Pathway Initiative (CDEIPI) aims to establish programs to develop pathways for successful careers in HIV science among scholars from underrepresented racial and ethnic populations. This article describes cross-site evaluation outcomes during the first 18 months (July 2021-December 2022) across 15 programs. METHODS: The aims of the evaluation were to characterize participants, describe feasibility, challenges, and successes of the programs and provide a basis for the generalizability of best practices to Diversity, Equity, and Inclusion (DEI) programs in the United States. Two primary data collection methods were used: a quarterly programmatic monitoring process and a centrally managed, individual-level, participant quantitative and qualitative survey. RESULTS: During the first year of evaluation data collection, 1085 racially and ethnically diverse scholars ranging from the high school to postdoctoral levels applied for CDEIPI programs throughout the United States. Of these, 257 (23.7%) were selected to participate based on program capacity and applicant qualifications. Participants were trained by 149 mentors, teachers, and staff. Of the N = 95 participants responding to the individual-level survey, 95.7% agreed or strongly agreed with statements of satisfaction with the program, 96.8% planned to pursue further education, and 73.7% attributed increased interest in a variety of HIV science topics to the program. Qualitative findings suggest strong associations between mentorship, exposure to scientific content, and positive outcomes. CONCLUSIONS: These data provide evidence to support the feasibility and impact of novel DEI programs in HIV research to engage and encourage racially and ethnically diverse scholars to pursue careers in HIV science.

ABSTRACT

BACKGROUND: There is an urgent need to increase diversity among scientific investigators in the HIV research field to be more reflective of communities highly affected by the HIV epidemic. Thus, it is critical to promote the inclusion and advancement of early-stage scholars from racial and ethnic groups underrepresented in HIV science and medicine. METHODS: To widen the HIV research career pathway for early-stage scholars from underrepresented minority groups, the National Institutes of Health supported the development of the Centers for AIDS Research (CFAR) Diversity, Equity, and Inclusion Pathway Initiative (CDEIPI). This program was created through partnerships between CFARs and Historically Black Colleges and Universities and other Minority Serving Institutions throughout the United States. RESULTS: Seventeen CFARs and more than 20 Historically Black Colleges and Universities and Minority Serving Institutions have participated in this initiative to date. Programs were designed for the high school (8), undergraduate (13), post baccalaureate (2), graduate (12), and postdoctoral (4) levels. Various pedagogical approaches were used including didactic seminar series, intensive multiday workshops, summer residential programs, and mentored research internship opportunities. During the first 18 months of the initiative, 257 student scholars participated in CDEIPI programs including 150 high school, 73 undergraduate, 3 post baccalaureate, 27 graduate, and 4 postdoctoral students. CONCLUSION: Numerous student scholars from a wide range of educational levels, geographic backgrounds, and racial and ethnic minority groups have engaged in CDEIPI programs. Timely and comprehensive program evaluation data will be critical to support a long-term commitment to this unique training initiative.

ABSTRACT

BACKGROUND: The underrepresentation of historically marginalized groups in the HIV research workforce is a barrier to reaching national Ending the Epidemic goals. SETTING: The Harvard University Center for AIDS Research (HU CFAR) Diversity Equity and Inclusion Working Group (DEI WG) uses a multifaceted approach to enhance the field's diversity. METHODS: We established a DEI WG to improve the recruitment, inclusion, and retention of underrepresented minorities (URMs) in HIV research. We use community-based, participatory processes to establish and expand education and outreach programs about HIV care and research to better connect the HU CFAR to communities affected by HIV. This article reports on the development of the WG in July 2022, progress in its first year, and future plans. RESULTS: We have built a network of >50 investigators across the university for monthly meetings; partnered with existing research pathway programs for high school, undergraduate, and graduate students, directly supporting 7 new trainees and linking CFAR investigators to additional mentorship opportunities; and created 2-year Scholar Awards for 5 URM investigators in HIV. Planned work includes needs assessments for early-stage investigators to understand factors contributing to inclusion and retention and new pathway and outreach programming being developed with community partner minority-serving institutions. CONCLUSIONS: The HU CFAR DEI WG strives to ensure that individuals from underrepresented, marginalized, and minoritized communities have an opportunity to contribute to HIV research and that research is informed by the needs of the communities affected by the epidemic. An intersectional approach should be incorporated into HIV research pathway initiatives.

ABSTRACT

Although therapeutic B cell depletion dramatically resolves inflammation in many diseases in which antibodies appear not to play a central role, distinct extrafollicular pathogenic B cell subsets that accumulate in disease lesions have hitherto not been identified. The circulating immunoglobulin D (IgD)-CD27-CXCR5-CD11c+ DN2 B cell subset has been previously studied in some autoimmune diseases. A distinct IgD-CD27-CXCR5-CD11c- DN3 B cell subset accumulates in the blood both in IgG4-related disease, an autoimmune disease in which inflammation and fibrosis can be reversed by B cell depletion, and in severe COVID-19. These DN3 B cells prominently accumulate in the end organs of IgG4-related disease and in lung lesions in COVID-19, and double-negative B cells prominently cluster with CD4+ T cells in these lesions. Extrafollicular DN3 B cells may participate in tissue inflammation and fibrosis in autoimmune fibrotic diseases, as well as in COVID-19.

ABSTRACT

BACKGROUND: Polypharmacy, using five or more medications, may increase the risk of nonadherence to prescribed treatment. We aimed to identify the interrelationship between trajectories of adherence to antiretroviral therapy (ART) and polypharmacy. METHODS: We included women with HIV (aged ≥ 18) enrolled in the Women's Interagency HIV Study in the United States from 2014 to 2019. We used group-based trajectory modeling (GBTM) to identify trajectories of adherence to ART and polypharmacy and the dual GBTM to identify the interrelationship between adherence and polypharmacy. RESULTS: Overall, 1,538 were eligible (median age of 49 years). GBTM analysis revealed five latent trajectories of adherence with 42% of women grouped in the consistently moderate trajectory. GBTM identified four polypharmacy trajectories with 45% categorized in the consistently low group. CONCLUSIONS: The joint model did not reveal any interrelationship between ART adherence and polypharmacy trajectories. Future research should consider examining the interrelationship between both variables using objective measures of adherence.

ABSTRACT

Fever is a common presentation to urgent-care services and is linked to multiple disease processes. To rapidly determine the etiology of fever, improved diagnostic modalities are necessary. This prospective study of 100 hospitalized febrile patients included both positive (FP) and negative (FN) subjects in terms of infection status and 22 healthy controls (HC). We evaluated the performance of a novel PCR-based assay measuring five host mRNA transcripts directly from whole blood to differentiate infectious versus non-infectious febrile syndromes as compared to traditional pathogen-based microbiology results. The FP and FN groups observed a robust network structure with a significant correlation between the five genes. There were statistically significant associations between positive infection status and four of the five genes: IRF-9 (OR = 1.750, 95% CI = 1.16-2.638), ITGAM (OR = 1.533, 95% CI = 1.047-2.244), PSTPIP2 (OR = 2.191, 95% CI = 1.293-3.711), and RUNX1 (OR = 1.974, 95% CI = 1.069-3.646). We developed a classifier model to classify study participants based on these five genes and other variables of interest to assess the discriminatory power of the genes. The classifier model correctly classified more than 80% of the participants into their respective groups, i.e., FP or FN. The GeneXpert prototype holds promise for guiding rapid clinical decision-making, reducing healthcare costs, and improving outcomes in undifferentiated febrile patients presenting for urgent evaluation.

ABSTRACT

BACKGROUND: Women with HIV (WHIV) in the United States face many challenges with adherence to antiretroviral therapy (ART), and suboptimal adherence often leads to virologic failure. This study aimed to determine the association between ART adherence trajectories and the risk of virologic failure. METHODS: We included WHIV (aged 18 years or older) enrolled in the Women's Interagency HIV Study in the United States from April 2014 to September 2019 who had at least 2 consecutive measurements of HIV RNA and ≥3 measurements of self-reported adherence. Group-based trajectory modeling was used to identify adherence trajectories. Cox proportional hazard ratios were used to measure the association. MAIN OUTCOME MEASURE: Virologic failure was defined as HIV RNA ≥200 copies/mL at 2 consecutive visits. RESULTS: We included 1437 WHIV (median age 49 years). Of all women, 173 (12.0%) experienced virologic failure. Four adherence trajectories were identified, namely "consistently high" (26.3%), "moderate increasing" (9.5%), "moderate decreasing" (30.6%), and "consistently low" (33.5%). Women in the consistently low adherence group consumed alcohol and experienced depression more than other groups. Compared with the "consistently high" trajectory, the risk of virologic failure was higher among women with "consistently low" [adjusted hazard ratio (aHR) 2.8; 95% confidence interval (CI): 1.6 to 4.9; P < 0.001] and "moderate decreasing" adherence trajectories (aHR 1.8; 95% CI: 1.0 to 3.2; P = 0.04), but it was similar to those with "moderate increasing" adherence trajectory (aHR 1.0; 95% CI: 0.4 to 2.5; P = 0.94). CONCLUSIONS: Adherence to ART remains a challenge among WHIV. Multilevel behavioral interventions to address poor adherence, alcohol consumption, and depression are needed.

ABSTRACT

Human broadly neutralizing antibodies (bnAbs) targeting the hemagglutinin stalk of group 1 influenza A viruses (IAVs) are biased for IGHV1-69 alleles that use phenylalanine (F54) but not leucine (L54) within their CDRH2 loops. Despite this, we demonstrated that both alleles encode for human IAV bnAbs that employ structurally convergent modes of contact to the same epitope. To resolve differences in lineage expandability, we compared F54 versus L54 as substrate within humanized mice, where antibodies develop with human-like CDRH3 diversity but are restricted to single VH genes. While both alleles encoded for bnAb precursors, only F54 IGHV1-69 supported elicitation of heterosubtypic serum bnAbs following immunization with a stalk-only nanoparticle vaccine. L54 IGHV1-69 was unproductive, co-encoding for anergic B cells and autoreactive stalk antibodies that were cleared from B cell memory. Moreover, human stalk antibodies also demonstrated L54-dependent autoreactivity. Therefore, IGHV1-69 polymorphism, which is skewed ethnically, gates tolerance and vaccine expandability of influenza bnAbs.

ABSTRACT

Treatments for HIV and other STIs are not readily available in sub-Saharan Africa and other resource-limited areas, where the prevalence of HIV and other STIs is high. In the absence of treatment and laboratory infrastructure to monitor treatment efficacy, increasing awareness of STIs and STI screening are crucial components of STI prevention programs. In the current study, we sought to estimate the awareness of STIs in resource-limited countries and evaluate the strength of the association between the awareness of STIs and STIs infection. We did a secondary analysis of data obtained from 2019 women and 794 men enrolled in a community-based study that was conducted from November 2002 to March 2003 in the Moshi Urban District of Northern Tanzania. We found gonorrhea, syphilis, and HIV/AIDS were well-known among the study participants. However, their awareness of other STIs, including herpes, was very low. We also found that the awareness of STIs was not associated with STIs in men, but women who had prior knowledge of gonorrhea, syphilis, and HIV had a twofold higher risk of testing positive for an STI. Education programs aimed at increasing awareness of STIs are needed in the region. The majority of the existing STI education programs in the region focus exclusively on HIV/AIDS. The expansion of the existing AIDS/HIV education programs needs to be strengthened to include information about other STIs.

ABSTRACT

Interleukin-6 (IL-6) has been linked to several life-threatening disease processes. Developing a point-of-care testing platform for the immediate and accurate detection of IL-6 concentrations could present a valuable tool for improving clinical management in patients with IL-6-mediated diseases. Drawing on an available biobank of samples from 35 patients hospitalized with COVID-19, a novel quantum-magnetic sensing platform is used to determine plasma IL-6 concentrations. A strong correlation was observed between IL-6 levels measured by QDTI10x and the Luminex assay (r = 0.70, p-value < 0.001) and between QDTI80x and Luminex (r = 0.82, p-value < 0.001). To validate the non-inferiority of QDTI to Luminex in terms of the accuracy of IL-6 measurement, two clinical parameters­the need for intensive care unit admission and the need for mechanical intubation­were chosen. IL-6 concentrations measured by the two assays were compared with respect to these clinical outcomes. Results demonstrated a comparative predictive performance between the two assays with a significant correlation coefficient. Conclusion: In short, the QDTI assay holds promise for implementation as a potential tool for rapid clinical decision in patients with IL-6-mediated diseases. It could also reduce healthcare costs and enable the development of future various biomolecule point-of-care tests for different clinical scenarios.

ABSTRACT

BACKGROUND: It is estimated that there are 3.8 million breast cancer survivors in the United States. Addressing survivors' post-treatment needs is critical to providing quality healthcare. METHODS: A standardized questionnaire for breast cancer survivors was employed to assess the health status, challenges, and concerns of our breast cancer patients at their survivorship visits, which were conducted 4 months after surgery. All patients were seen in the breast center at one community hospital over a 6-year period. RESULTS: Responses to a standardized questionnaire that was administered to 505 consecutive breast cancer patients at their survivorship visits 4 months after surgery were evaluated. The most striking finding was that 35% reported symptoms of insomnia, 26% had persistent fatigue, and 19% experienced fatigue that interfered with their usual activities. There was a significant association between symptoms of insomnia and radiation treatment (P = .004), pain (P < .001), hormone therapy (P < .01), and side effects of hormone therapy (P < .0001). There was also a significant association between fatigue and pain (P < .001) as well as side effects from hormone treatment (P = .0036). CONCLUSIONS: Over a third (35%) of breast cancer patients suffer from insomnia, while over a quarter (26%) complain of fatigue at their survivorship assessments. Contributing factors include radiation treatment, pain, and hormonal therapy. Careful assessment and treatment of fatigue and symptoms of insomnia in breast cancer patients is needed to improve quality of life for survivors.

ABSTRACT

Vaginal microbiota composition affects many facets of reproductive health. Lactobacillus iners-dominated microbial communities are associated with poorer outcomes, including higher risk of bacterial vaginosis (BV), compared with vaginal microbiota rich in L. crispatus. Unfortunately, standard-of-care metronidazole therapy for BV typically results in dominance of L. iners, probably contributing to post-treatment relapse. Here we generate an L. iners isolate collection comprising 34 previously unreported isolates from 14 South African women with and without BV and 4 previously unreported isolates from 3 US women. We also report an associated genome catalogue comprising 1,218 vaginal Lactobacillus isolate genomes and metagenome-assembled genomes from >300 women across 4 continents. We show that, unlike L. crispatus, L. iners growth is dependent on L-cysteine in vitro and we trace this phenotype to the absence of canonical cysteine biosynthesis pathways and a restricted repertoire of cysteine-related transport mechanisms. We further show that cysteine concentrations in cervicovaginal lavage samples correlate with Lactobacillus abundance in vivo and that cystine uptake inhibitors selectively inhibit L. iners growth in vitro. Combining an inhibitor with metronidazole promotes L. crispatus dominance of defined BV-like communities in vitro by suppressing L. iners growth. Our findings enable a better understanding of L. iners biology and suggest candidate treatments to modulate the vaginal microbiota to improve reproductive health for women globally.

ABSTRACT

BACKGROUND: This study addresses the effectiveness of risk models and screening breast magnetic resonance imaging (MRI) in women who have atypical hyperplasia (AH), lobular carcinoma in situ (LCIS), or a family history of breast cancer, but not a genetic mutation. PATIENTS AND METHODS: A retrospective review of 444 women who had 458 breast screening MRIs at a community teaching hospital over a 12-month period between March 25, 2014 and March 31, 2015 was performed. The patients underwent high risk screening with breast MRIs alternating with mammograms every 6 months. After excluding patients with prior breast or ovarian cancer, genetic mutations, and chest wall radiation, 200 remaining patients constituted the study cohort. Over the following 5 years, the patients were screened with MRIs alternating with mammograms every 6 months. A total of 961 total MRI screenings were performed over the entire 5-year period of the study. RESULTS: A total of 200 women fit the study criteria. Of these 103 had a prior history of AH or LCIS. Over the 5-year period, 60 women dropped out of the screening regimen, 6 patients were diagnosed with breast cancer on screening MRIs, and 2 additional patients were diagnosed with breast cancer on screening mammograms. Surprisingly, the highest Tyrer-Cuzick (T-C) scores did not correlate with increased development of breast cancers in our population. CONCLUSIONS: This study shows that there is wide variation in the results of risk assessment models. Risk models may overestimate breast cancer risk, suggesting that re-evaluation of current risk assessment and screening protocols is warranted.

ABSTRACT

OBJECTIVE: Black individuals in the USA are arrested and incarcerated at a significantly higher rate than White individuals, and incarceration is associated with increased HIV vulnerability. Pre-exposure prophylaxis (PrEP) reduces the risk for HIV transmission, but little is known about the relationship between HIV risk behavior and willingness to use PrEP among Black individuals with an arrest history. METHOD: A total of 868 individuals completed a nationally representative survey and provided baseline data on sexual risk. Participants were grouped as those with a history of arrest (N = 226) and those with no history of arrest (N=619) based on self-reported arrest history. Our study examined HIV risk behaviors associated with willingness to use PrEP between those with arrest history and those without arrest history. RESULTS: Participants with an arrest history were more likely to have a lifetime history of anal sex (p<0.0001) and sexually transmitted diseases (p=0.0007). A history of multiple sexual partners in the past 3 months was associated with PrEP willingness in individuals with an arrest history [aPR 2.61 (1.77, 3.85), p<0.0001], adjusting for other covariates in the model. CONCLUSIONS: Differences in risk behavior and willingness to use PrEP exist by arrest history. Understanding these risk behaviors are necessary to increase access to PrEP. PrEP uptake and adherence interventions, when recommended and made available for individuals at substantive risk of HIV infection at the time of arrest and during incarceration, are essential to reducing the spread of HIV in correctional facilities and in communities to which they return.
