RESUMO

BACKGROUND: Little is known about penile high-risk HPV among MSM in low-and-middle income countries. We aimed to determine the incidence, clearance and persistence of penile hrHPV among Rwandan MSM. METHODS: We enrolled 350 MSM (345 with valid HPV results), aged ≥18 years, at each visit (6-12 months apart), we collected penile PreservCyt specimens and blood for HPV and HIV testing, socio-demographic and behavioral variables. HPV testing was performed using the Ampfire assay. Penile hrHPV incidence and clearance/1,000 person-months of follow-up (PMF), prevalent- and incident-persistence were computed and compared by HIV status. RESULTS: The mean age was 27.7 ± 6.7 years and 19.4% were living with HIV. Penile hrHPV incidence was 34.8 (95% CI: 29.1, 41.8)/1,000 PMF. HPV16 (11.7, CI 9.26, 14.9) and HPV59 (6.1, CI 4.52, 8.39) had the highest incidence rates. Prevalent- and incident-persistence were 47.5% and 46.6%, respectively. HPV66 (33.3%), HPV52 (30.8%) and HPV16 (29.2%) had the highest prevalent-persistence and HPV33 (53.8%), HPV31 (46.7%) and HPV16 (42.6%) the highest incident-persistence. No differences were found by HIV status except for HPV45 (higher in MSM with HIV). CONCLUSION: We found high incidence and prevalent/incident-persistence of penile hrHPV among Rwandan MSM. This highlights the importance of preventive strategies for HPV-associated anogenital cancers.

RESUMO

Introduction: Pre-exposure Prophylaxis (PrEP) is a daily pill aimed at reducing HIV transmission risk when taken as prescribed. It's highly recommended for high-risk Men who have sex with Men (MSM). This study aimed to assess PrEP awareness and willingness to use it among Rwandan MSM, a critical aspect given PrEP's proven effectiveness. The findings are expected to inform policy decisions and further advance the implementation of PrEP strategies. Methods: This is a cross-sectional study design that utilized a web-based survey conducted between April and June 2019 to assess awareness and willingness to use PrEP among sexually active MSM in Rwanda. A snowball sampling technique was used to recruit participants via social media such as WhatsApp and e-mail. Eligibility criteria included being sexually active, aged ≥18 years, self-identifying as MSM, residing in Rwanda, self-reported engagement in receptive or insertive anal sex in the last 12 months, and self-reported HIV-negative serostatus. We assessed two primary outcomes: PrEP awareness (having ever heard of PrEP) and willingness to use PrEP within one month of completing the survey. Multivariable logistic regression was performed to identify participant characteristics associated with PrEP awareness and willingness to use it. Results: Out of 521 participants, the majority (73%) demonstrated awareness of PrEP. Factors linked to PrEP awareness included residing outside the capital, Kigali, being in the 18-29 age group, having higher education levels, perceiving a benefit from PrEP, and engaging in vaginal sex with a woman while using a condom in the last year. Additionally, 96% of participants expressed a strong willingness to use PrEP. Conclusion: Rwandan MSM exhibits a high level of PrEP awareness, notably associated with factors like location, age, education, perceived benefits, and condom use. The study also revealed a strong willingness to use PrEP, indicating promising prospects for its adoption among this group. These findings highlight the need for targeted awareness campaigns, personalized interventions, and comprehensive sexual health education to promote PrEP adoption and strengthen HIV prevention efforts among Rwandan MSM.

RESUMO

Introduction: Pre-exposure Prophylaxis (PrEP) is a daily pill intended to reduce the risk of acquiring Human Immunodeficiency Virus (HIV) when taken as prescribed. It is strongly recommended for Men who have sex with Men (MSM) at high risk of HIV transmission to minimize infection risk. Despite its proven effectiveness, there is a lack of information about awareness and willingness to use PrEP among Rwandan MSM. In the context of HIV acquisition, the purpose of this study was to ascertain the awareness and willingness to use PrEP among high-risk Rwandan MSM. The findings of this research will provide valuable perspectives to mold policy and direct the effective execution of PrEP within the country. Method: This is a cross-sectional study design that utilized a web-based survey conducted between April and June 2019 to assess awareness and willingness to use PrEP among sexually active MSM in Rwanda. A snowball sampling technique was used to recruit participants who were contacted via social medial such as WhatsApp and e-mail. To be eligible, participants were supposed to be sexually active, aged ≥18 years, self-identify as MSM, residence in Rwanda, self-reported engagement in receptive or insertive anal sex in the last 12 months, and self-reported HIV-negative sero-status. We assessed two primary outcomes: PrEP awareness (having ever heard of PrEP) and willingness to use PrEP within one month of completing the survey. Multivariable logistic regression was performed to identify participant characteristics associated with PrEP awareness and willingness to use it. Results: Among the 521 participants included in the analysis, 63% were aged below 24 years. The majority (73%) demonstrated awareness of PrEP. Factors associated with PrEP awareness included residing outside of the capital, Kigali, as opposed to living in Kigali (adjusted odds ratio [aOR] 2.35, 95% confidence interval [CI] 1.40-3.97), being in the age groups 18-24 years (aOR 2.28, 95% CI: 1.03-5.01) or 25-29 years (aOR 3.06, 95% CI 1.35-6.93) compared to those aged 30 or older, having higher education levels, such as completing secondary education (aOR 1.76, 95% CI 1.01-3.06) or university education (aOR 2.65, 95% CI 1.18-5.96) in contrast to having no education. Lastly, perceiving a benefit from PrEP (aOR 9.52, 95% CI 4.27-21.22), and engaging in vaginal sex with a woman using a condom in the last 12 months (aOR 1.82, 95% CI 1.14-2.91) versus not. Impressively, 96% of participants expressed a strong willingness to use PrEP. Conclusion: Among Rwandan MSM, there is a high level of awareness of PrEP, notably associated with factors such as residing outside Kigali, younger age, higher education, perceived benefits of PrEP and condom use during vaginal sex in the past year. Furthermore, a significant portion of participants demonstrated an intense desire to use PrEP, suggesting promising possibilities for its extensive implementation among this group of people. The findings from this study emphasize the importance of implementing highly focused awareness campaigns, personalized intervention, and comprehensive sexual health education programs in order to enhance the adoption of PrEP and bolster HIV prevention initiatives among the Rwandan population of MSM.

RESUMO

Introduction: The AmpFire HPV genotyping Assay (Atila Biosystems, Mountain View, CA, USA) is a new test for which there are few data regarding its analytic performance and reliability. Using anal and penile swab specimens from a cohort study of men who have sex with men (MSM) in Rwanda, we compared high-risk HPV (hrHPV) detection by AmpFire done at two laboratories, one at University of California San Francisco (UCSF) and the other Rwanda Military Hospital, and well-validated MY09/11-based assay done at UCSF. Methods: Anal and penile specimens collected from 338 MSM from March 2016 to September 2016 were tested for high-risk HPV genotypes (hrHPV) by MY09/11, AmpFire UCSF and AmpFire RMH. Cohen's kappa coefficient was used to test for reproducibility. Results: The hrHPV positivity by MY09/11 and AmpFire UCSF was 13% and 20.7% (k = 0.73) for anal specimens and was 26.3% and 32.6% (k = 0.67) for penile specimens. Specifically, good reproducibility was for types 16 and 18 (k = 0.69 and k = 0.71) for anal specimens and (k = 0.50 and k = 0.72) for penile specimens. The hrHPV positivity by AmpFire at UCSF and RMH was 20.7% for both laboratories (k = 0.87) for anal specimens and was 34.9% and 31.9% (k = 0.89) for penile specimens. Specifically, excellent reproducibility was for types 16 and 18 for anal specimens (k = 0.80 and k = 1.00) and penile specimens (k = 0.85 and k = 0.91). Conclusion: Results show that MY09/11 and AmpFire assays have good reproducibility while the AmpFire UCSF and RMH assays have excellent reproducibility. These results show that AmpFire is a promising HPV genotyping test.

RESUMO

OBJECTIVE: Marijuana, tobacco and alcohol use are prevalent among people with HIV and may adversely affect kidney function in this population. We determined the association of use of these substances with estimated glomerular filtration rate (eGFR) among women with HIV (WWH) and women without HIV. DESIGN: We undertook a repeated measures study of 1043 WWH and 469 women without HIV within the United States Women's Interagency HIV Study, a multicenter, prospective cohort of HIV-seropositive and HIV-seronegative women. METHODS: We quantified substance exposures using semi-annual questionnaires. Using pooled eGFR data from 2009 to 2019, we used linear regression models with multivariable generalized estimating equations to ascertain associations between current and cumulative substance use exposures with eGFR, adjusting for sociodemographics, chronic kidney disease risk factors and HIV-related factors. RESULTS: Marijuana use of 1-14 days/month versus 0 days/month was associated with 3.34 ml/min per 1.73 m 2 [95% confidence interval (CI) -6.63, -0.06] lower eGFR and marijuana use of >0.02-1.6 marijuana-years versus 0-0.2 marijuana-years was associated with 3.61 ml/min per 1.73 m 2 (95% CI -5.97, -1.24) lower eGFR. Tobacco use was not independently associated with eGFR. Alcohol use of seven or more drinks/week versus no drinks/week was associated with 5.41 ml/min per 1.73 m 2 (95% CI 2.34, 8.48) higher eGFR and alcohol use of >0.7-4.27 drink-years and >4.27 drink-years versus 0-0.7 drink-years were associated with 2.85 ml/min per 1.73 m 2 (95% CI 0.55, 5.15) and 2.26 ml/min per 1.73 m 2 (95% CI 0.33, 4.20) higher eGFR, respectively. CONCLUSION: Among a large cohort of WWH and women without HIV, marijuana use was associated with a lower eGFR while alcohol use was associated with a higher eGFR.

RESUMO

Despite improved clinical outcomes of initiating antiretroviral therapy (ART) soon after diagnosis, conflicting evidence exists regarding the impact of same-day ART initiation on subsequent clinical outcomes. We aimed to characterize the associations of time to ART initiation with loss to care and viral suppression in a cohort of newly diagnosed people living with HIV (PLHIV) entering care after Rwanda implemented a national "Treat All" policy. We conducted a secondary analysis of routinely collected data of adult PLHIV enrolling in HIV care at 10 health facilities in Kigali, Rwanda. Time from enrollment to ART initiation was categorized as same day, 1-7 days, or >7 days. We examined associations between time to ART and loss to care (>120 days since last health facility visit) using Cox proportional hazards models, and between time to ART and viral suppression using logistic regression. Of 2,524 patients included in this analysis, 1,452 (57.5%) were women and the median age was 32 (interquartile range: 26-39). Loss to care was more frequent among patients who initiated ART on the same day (15.9%), compared with those initiating ART 1-7 days (12.3%) or >7 days (10.1%), p < .001. In multivariable analyses, same-day ART initiation was associated with a greater hazard of loss to care compared with initiating >7 days after enrollment (adjusted hazard ratio 1.39, 95% confidence interval: 1.04-1.85). A total of 1,698 (67.3%) had available data on viral load measured within 455 days after enrollment. Of these, 1,476 (87%) were virally suppressed. A higher proportion of patients initiating ART on the same day were virally suppressed (89%) compared with those initiating 1-7 days (84%) or >7 days (88%) after enrollment. This association was not statistically significant. Our findings suggest that ensuring adequate, early support for PLHIV initiating ART rapidly may be important to improve retention in care for newly diagnosed PLHIV in the era of Treat All.

RESUMO

BACKGROUND: Estrogen-based hormone therapy (HT) may have beneficial cardiovascular effects when initiated in early menopause. This has not been examined in women with human immunodeficiency virus (HIV), who have heightened immune activation and cardiovascular risks. METHODS: Among 609 postmenopausal women (1234 person-visits) in the Women's Interagency HIV Study, we examined the relationship of ever HT use (oral, patch, or vaginal) with subclinical atherosclerosis: carotid artery intima-media thickness (CIMT), distensibility, and plaque assessed via repeated B-mode ultrasound imaging (2004-2013). We also examined associations of HT with cross-sectional biomarkers of immune activation and D-dimer. Statistical models were adjusted for sociodemographic, behavioral, and cardiometabolic factors. RESULTS: Women (mean age, 51 years; 80% HIV positive) who ever used HT at baseline were older, and more likely to be non-Hispanic White and report higher income, than never-users. Women who ever used HT had 43% lower prevalence of plaque (prevalence ratio, 0.57 [95% confidence interval {CI}, .40-.80]; P < .01), 2.51 µm less progression of CIMT per year (95% CI, -4.60, to -.41; P = .02), and marginally lower incidence of plaque over approximately 7 years (risk ratio, 0.38 [95% CI, .14-1.03; P = .06), compared with never-users, adjusting for covariates; ever HT use was not associated with distensibility. These findings were similar for women with and without HIV. Ever HT use was associated with lower serum D-dimer, but not with biomarkers of immune activation after covariate adjustment. CONCLUSIONS: HT may confer a subclinical cardiovascular benefit in women with HIV. These results begin to fill a knowledge gap in menopausal care for women with HIV, in whom uptake of HT is very low.

RESUMO

Introduction: We previously reported the initial results of a phase II multicenter transplant trial using haploidentical parental donors for children and aolescents with high-risk sickle cell disease achieving excellent survival with exceptionally low rates of graft-versus-host disease and resolution of sickle cell disease symptoms. To investigate human leukocyte antigen (HLA) sensitization, graft characteristics, donor chimerism, and immune reconstitution in these recipients. Methods: CD34 cells were enriched using the CliniMACS® system with a target dose of 10 x 106 CD34+ cells/kg with a peripheral blood mononuclear cell (PBMNC) addback dose of 2x105 CD3/kg in the final product. Pre-transplant HLA antibodies were characterized. Donor chimerism was monitored 1-24 months post-transplant. Comprehensive assessment of immune reconstitution included lymphocyte subsets, plasma cytokines, complement levels, anti-viral T-cell responses, activation markers, and cytokine production. Infections were monitored. Results: HLA antibodies were detected in 7 of 11 (64%) evaluable patients but rarely were against donor antigens. Myeloid engraftment was rapid (100%) at a median of 9 days. At 30 days, donor chimerism was 93-99% and natural killer cell levels were restored. By 60 days, CD19 B cells were normal. CD8 and CD4 T-cells levels were normal by 279 and 365 days, respectively. Activated CD4 and CD8 T-cells were elevated at 100-365 days post-transplant while naïve cells remained below baseline. Tregs were elevated at 100-270 days post-transplant, returning to baseline levels at one year. At one year, C3 and C4 levels were above baseline and CH50 levels were near baseline. At one year, cytokine levels were not significantly different from baseline. Discussion: These results suggest that haploidentical transplantation with CD34-enriched cells and peripheral blood mononuclear cell addback results in rapid engraftment, sustained donor chimerism and broad-based immune reconstitution.

RESUMO

OBJECTIVE: To describe medical student attitudes and exposure to abortion and pregnancy options counseling and influences of that experience on the provision of these services in their future practice. STUDY DESIGN: A survey was conducted of 3rd and 4th year medical students in 2019 at an US medical school in the Northeast. RESULTS: One hundred and sixty-two students participated in the survey (response rate = 46 %, 162/353). Only 27 % reported receiving at least one educational lecture on abortion during medical school. Fifty-eight percent reported clinical exposure to surgical abortion. About 2/3 reported being somewhat likely to provide abortions in the future, despite most identifying as "pro-choice." There was significant association between clinical exposure to surgical abortion and desire to include abortion in future practice (P = 0.03). The most common objections to performing future abortions were personal values, religious objection, and lack of training/experience. Most respondents did not feel comfortable providing counseling for abortion or adoption. Combined, only 14.4 % reported that they would be at least somewhat likely to apply to obstetrics-gynecology or family medicine residency programs, including programs with opportunities for such training. CONCLUSIONS: Earlier work has shown that medical student intentions to provide abortions prior to residency are better predictors of future abortion provision than during residency. Thus, medical school is a critical time for exposure to abortion and pregnancy options counseling. Such exposure and medical student attitudes are areas of research that should be further studied to contribute to the expansion and normalization of these services.

RESUMO

INTRODUCTION: Bone loss and cognitive impairment are common in women living with HIV (WLWH) and are exacerbated by menopause. Bone-derived undercarboxylated osteocalcin (ucOCN) and sclerostin appear to influence cognition. The current study investigated whether the circulating levels of these 2 proteins are associated with cognition in midlife WLWH and demographically similar HIV seronegative women. METHODS: Plasma samples from women enrolled in a musculoskeletal substudy within the Women's Interagency HIV Study were used to measure ucOCN and sclerostin. A neuropsychological (NP) test battery assessing executive function, processing speed, attention/working memory, learning, memory, verbal fluency, and motor function was administered within 6 months of musculoskeletal enrollment and every 2 years after (1-4 follow-up visits per participant). A series of generalized estimating equations were conducted to examine the association between biomarkers and NP performance at the initial assessment and over time in the total sample and in WLWH only. Primary predictors included biomarkers, time, and biomarker by time interactions. If the interaction terms were not significant, models were re-run without interactions. RESULTS: Neither biomarker predicted changes in NP performance over time in the total sample or in WLWH. ucOCN was positively associated with executive function in the total sample and in WLWH and with motor skills in WLWH. ucOCN was negatively associated with attention/working memory in the total sample. There were no significant associations between sclerostin and NP performance. CONCLUSION: The current study suggests an association between bone-derived ucOCN and cognition in women with and without HIV infection.

RESUMO

OBJECTIVE: CXCR4 (X4)-tropic HIV-1 was found previously to herald CD4 + cell depletion and disease progression in individuals who were antiretroviral-naive or took combination antiretroviral therapy (cART) for less than 5 years. We updated this finding by investigating whether the deleterious effect of X4-tropic strains is mitigated by long-term cART. DESIGN: We examined morbidity and mortality in relation to HIV-1 tropism and cART in 529 participants followed up to 18 years in the Women's Interagency HIV Study; 91% were women of color. METHODS: Plasma-derived HIV-1 tropism was determined genotypically. RESULTS: We categorized participants according to the number of visits reported on cART after initiation. Group 1: three or less visits, 74% of these participants reporting no cART; group 2: at least four visits and less than 70% of visits on cART; group 3: at least 70% of visits on cART. AIDS mortality rates for participants in each group with X4 virus compared with those with R5 virus exclusively were, respectively: 62 vs. 40% ( P  = 0.0088); 23% vs. 22% [nonsignificant (NS)]; 7% vs. 14% (NS). Kaplan-Meier curves showed accelerated progression to AIDS death or AIDS-defining illness in participants with three or less cART visits and X4 viruses ( P  = 0.0028) but no difference in progression rates stratified by tropism in other groups. Logistic regression found that HIV-1 suppression for at least 10 semiannual visits (≥5 years total) mitigated X4 tropism's deleterious effect on mortality, controlling for maximal viral load, and CD4 + nadir. CONCLUSION: Long-term cART markedly mitigated the deleterious effect of X4 viruses on AIDS morbidity and mortality. Mitigation was correlated with duration of viral suppression, supporting HIV-1 suppression as a crucial goal.

RESUMO

INTRODUCTION: Lifestyle improvements are key modifiable risk factors for Type 2 diabetes mellitus (DM) however specific influences of biologically active dietary metabolites remain unclear. Our objective was to compare non-targeted plasma metabolomic profiles of women with versus without confirmed incident DM. We focused on three lipid classes (fatty acyls, prenol lipids, polyketides). MATERIALS AND METHODS: Fifty DM cases and 100 individually matched control participants (80% with human immunodeficiency virus [HIV]) were enrolled in a case-control study nested within the Women's Interagency HIV Study. Stored blood samples (1-2 years prior to DM diagnosis among cases; at the corresponding timepoint among matched controls) were assayed in triplicate for metabolomics. Time-of-flight liquid chromatography mass spectrometry with dual electrospray ionization modes was utilized. We considered 743 metabolomic features in a two-stage feature selection approach with conditional logistic regression models that accounted for matching strata. RESULTS: Seven features differed by DM case status (all false discovery rate-adjusted q<0.05). Three flavonoids (two flavanones, one isoflavone) were respectively associated with lower odds of DM (all q<0.05), and sorbic acid was associated with greater odds of DM (all q<0.05). CONCLUSION: Flavonoids were associated with lower odds of incident DM while sorbic acid was associated with greater odds of incident DM.

RESUMO

We describe the design, implementation, and impact of a data harmonization, data quality checking, and dynamic report generation application in an international observational HIV research network. The IeDEA Harmonist Data Toolkit is a web-based application written in the open source programming language R, employs the R/Shiny and RMarkdown packages, and leverages the REDCap data collection platform for data model definition and user authentication. The Toolkit performs data quality checks on uploaded datasets, checks for conformance with the network's common data model, displays the results both interactively and in downloadable reports, and stores approved datasets in secure cloud storage for retrieval by the requesting investigator. Including stakeholders and users in the design process was key to the successful adoption of the application. A survey of regional data managers as well as initial usage metrics indicate that the Toolkit saves time and results in improved data quality, with a 61% mean reduction in the number of error records in a dataset. The generalized application design allows the Toolkit to be easily adapted to other research networks.

RESUMO

BACKGROUND: Fracture rates have been reported to be higher among older women living with HIV (WLWH) than HIV- women. Hormone therapy with estrogen can reduce vasomotor symptoms (VMS) associated with menopause and prevent fractures. As data are limited on the benefits of hormone therapy use in WLWH, we examined associations of hormone therapy, use and fractures. METHODS: A prospective study of 1765 (1350 WLWH and 415 HIV-) postmenopausal Women's Interagency HIV Study (WIHS) participants was performed, including self-reported hormone therapy, use and fracture data from 2003 to 2017. Proportional hazard models determined predictors of new fractures at any site or at typical fragility fracture sites (hip, spine, wrist). RESULTS: At the first postmenopausal visit, the median (IQR) age of WLWH was slightly younger than HIV- women [49.8 (46.4-53) vs. 50.7 (47.5-54), P  = 0.0002] and a smaller proportion of WLWH reported presence of VMS (17% vs. 26%, P  < 0.0001). A greater proportion of WLWH than HIV- women reported hormone therapy use (8% vs. 4%, P  = 0.007) at the first postmenopausal visit. In multivariate analyses, white race and smoking were significant predictors of incident fracture at any site but hormone therapy ( P  = 0.69) and HIV status ( P  = 0.53) were not. CONCLUSION: Our study did not find evidence of benefit or harm with regards to fracture outcomes in postmenopausal WLWH receiving hormone therapy. Further research is needed to determine whether hormone therapy has benefits beyond treatment of VMS, such as prevention of adverse aging-associated outcomes.

RESUMO

BACKGROUND: Cure rates for Hodgkin's lymphoma are excellent, but excess short-term and long-term morbidities from treatment remain a concern. Immunotherapy targeting both tumor antigens and the immunosuppressive tumor microenvironment in children, adolescents, and young adults with Hodgkin's lymphoma may improve early response rates and eliminate toxic chemotherapy and radiation, thus minimizing toxicity. We conducted a phase II study to evaluate the safety and overall response rate of brentuximab vedotin and rituximab in combination with risk-adapted chemotherapy in children, adolescents, and young adults with newly diagnosed classic Hodgkin's lymphoma (cHL). METHODS: This is a prospective, phase II, non-randomized, risk-assigned study. Patients were treated and evaluated between 2012 and 2020. Eligible patients were aged ≥1 and ≤30 years old with advanced stage, intermediate-risk, and high-risk newly diagnosed cHL. Patients received four or six cycles of brentuximab vedotin (1.2 mg/kg), doxorubicin (25 mg/m2), vinblastine (6 mg/m2), dacarbazine (375 mg/m2), and rituximab (375 mg/m2). Early response was evaluated following two cycles of therapy. Involved field radiotherapy (IFRT) was restricted to high-risk patients with both bulky disease and slow response or those not in complete response at the end of chemoimmunotherapy. RESULTS: Thirty patients were enrolled, with a median age of 15 years (4-23). There were 18 intermediate-risk and 12 high-risk patients. Toxicities included grade III mucositis (3%), infusion reaction (3%), and peripheral neuropathy (6%). There was a 100% complete response rate on completion of chemoimmunotherapy. Eighteen patients (60%) achieved a rapid early response. Four patients (13%) required IFRT. The 5-year event-free and overall survival rates were 100%, with a median follow-up of 62 months (18-105). CONCLUSIONS: Immunotherapy with brentuximab vedotin, rituximab, and risk-adapted chemotherapy is safe in children, adolescents, and young adults with newly diagnosed cHL. We have demonstrated 100% complete response and 100% event-free and overall survival rates at a median 5-year follow-up, with a significant reduction in use of more toxic chemotherapy and IFRT. A larger cohort is required to confirm these preliminary findings. TRIAL REGISTRATION NUMBER: NCT02398240.

RESUMO

BACKGROUND: Aging in people with HIV is associated with increased risk of developing synergistic conditions such as neurocognitive impairment, polypharmacy, and falls. We assessed associations between polypharmacy (use of 5 or more non-ART medications), use of neurocognitive adverse effects (NCAE) medications, and odds of falls in women with HIV (WWH) and without HIV (HIV-). METHODS: Self-reported falls and medication use data were contributed semiannually by 1872 (1315 WWH and 557 HIV-) Women's Interagency HIV Study participants between 2014 and 2016. Polypharmacy and NCAE medication use were evaluated separately and jointly in multivariable models to assess their independent contributions to single and multiple falls risk. RESULTS: The proportion of women who reported any fall was similar by HIV status (19%). WWH reported both greater polypharmacy (51% vs. 41%; P < 0.001) and NCAE medication use (44% vs. 37%; P = 0.01) than HIV- women. Polypharmacy conferred elevated odds of single fall [adjusted odds ratio (aOR) 1.67, 95% CI: 1.36 to 2.06; P < 0.001] and multiple falls (aOR 2.31, 95% CI: 1.83 to 2.93; P < 0.001); the results for NCAE medications and falls were similar. Both polypharmacy and number of NCAE medications remained strongly and independently associated with falls in multivariable models adjusted for HIV serostatus, study site, sociodemographics, clinical characteristics, and substance use. CONCLUSIONS: Polypharmacy and NCAE medication use were greater among WWH compared with HIV-, and both were independently and incrementally related to falls. Deprescribing and avoidance of medications with NCAEs may be an important consideration for reducing fall risk among WWH and sociodemographically similar women without HIV.

RESUMO

The number of people with HIV (PWH) experiencing age-associated comorbidities including those treated with medications and cognitive impairment is increasing. We examined associations between polypharmacy and cognition in older women with HIV (WWH) given their vulnerability to this comorbidity. Cross-sectional analysis capitalizing on Women's Interagency HIV Study data collected between 2014 and 2017. WWH meeting the following criteria were analyzed: age ≥50 years; availability of self-reported non-antiretroviral therapy (ART) medications data; and neuropsychological data. The number of non-ART medications used regularly in the prior 6 months was summed. Polypharmacy was categorized as none/low (0-4), moderate (5-9), or severe (≥10). Multivariable linear regression analyses examined polypharmacy-cognition (T-score) associations in the total sample and among virally suppressed (VS; < 20 copies/mL)-WWH after covariate adjustment for enrollment site, income, depressive symptoms, substance use (smoking, heavy alcohol, marijuana, crack, cocaine, and/or heroin), the Veterans Aging Cohort Study index (indicators of HIV disease and organ system function, hepatitis C virus serostatus), ART use, nadir CD4 count, and specific ART drugs (efavirenz, integrase inhibitors). We included 637 women (median age = 55 years; 72% Black). Ninety-four percent reported ART use in the past 6 months and 75% had HIV RNA <20 copies/mL. Comorbidity prevalence was high (61% hypertension; 26% diabetes). Moderate and severe polypharmacy in WWH were 34% and 24%. In WWH, severe polypharmacy was associated with poorer executive function (p = .007) and processing speed (p = .01). The same pattern of findings remained among VS-WWH. Moderate polypharmacy was not associated with cognition. Moderate and severe polypharmacy were common and associated with poorer executive function and processing speed in WWH. Severe polypharmacy may be a major contributor to the persistence of domain-specific cognitive complications in older WWH above and beyond the conditions that these medications are used to treat.

RESUMO

Allogeneic stem cell transplantation (AlloSCT) represents the only curative therapy for sickle cell disease (SCD). However, limited availability of matched related donors and suboptimal outcomes following AlloSCT with unrelated donors has led to investigation of alternative donors. Among children with high-risk SCD, we evaluated health-related quality of life (HRQoL) impact in the two years following familial haploidentical SCT. HRQoL was collected from parent and child raters, using the Child Health Ratings Inventories Generic measure and haploidentical SCT-specific module. Repeated measures models were fit to assess HRQoL changes over time and by rater. Nineteen children (mean age 12.9 yrs [standard deviation, 5.3]; 63% male) and their parents were included. There were no differences in the 2-yr trajectories of child physical or emotional functioning (EF) by rater. Child physical functioning and EF scores were significantly lower at day +45 than baseline, but scores recovered by day +180. There was significant improvement in EF (p = 0.03) at 2 yrs vs baseline. A similar pattern of scores over time was seen for parent ratings of child's global HRQoL. Despite treatment intensity in the initial months following AlloSCT, patient scores recovered or exceeded baseline scores at two years. This trial is registered at clinicaltrials.gov (NCT01461837).

RESUMO

Methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections are associated with significant morbidity and mortality. MRSA secretes a number of virulence factors and pore-forming toxins that enable tissue invasion. Prior studies have found associations between decreased toxin production and poor outcomes in invasive MRSA infection, particularly in pneumonia. In this retrospective observational cohort study of MRSA bacteremia in adult patients from 2007 to 2015, we examined whether cytotoxicity was associated with 30-day mortality. Isolates were obtained from 776 patients and screened for cytotoxicity in a human HL-60 cell model, antimicrobial susceptibility, and spa type, and clinical data were abstracted from charts. We did not find an association between low cytotoxic activity and 30-day mortality in univariate logistic regression analyses. There was a difference in distribution of the genotypes across cytotoxicity phenotypes, with spa-CC008 accounting for a larger proportion of isolates in the high cytotoxicity group. Isolates with a skin and soft tissue primary infective site had a higher median cytotoxicity. There was no association between cytotoxicity and host factors such as age or comorbidity burden. The isolates in our study came from heterogeneous primary sites of infection and were predominantly from spa-CC002 and spa-CC008 lineages, so it is possible that findings in prior studies reflect a different distribution in genotypes and clinical syndromes. Overall, in this large study of cytotoxicity of MRSA bloodstream isolates, we did not find the low cytotoxicity phenotype to be predictive of poor outcomes in MRSA bacteremia.

RESUMO

BACKGROUND: We previously reported lower bone mineral density (BMD) among premenopausal women with HIV (WWH) compared to women without HIV (HIV-). Rate of bone loss may be even greater for WWH during the menopausal transition. METHODS: Pre-, peri- and postmenopausal women in the Women\'s Interagency HIV Study (WIHS) underwent whole body DXA and central quantitative computed tomography to measure areal BMD (aBMD) and volumetric BMD (vBMD), respectively. Multivariable regression models with covariates associated with low aBMD (T score < -1.0) in univariate analyses (P≤.05) and known risk factors for low BMD assessed contributions of HIV and menopausal stage to the prediction of aBMD. RESULTS: Compared to HIV- women, in unadjusted analyses, WWH had 5-9% lower aBMD at the lumbar spine (P=.001), femoral neck (P=.04), total hip (P=.003) and the ultradistal radius (P=.004), and higher osteoporosis prevalence (T score<-2.5) at the ultradistal radius only (13.5% vs 0%, P=.0003). WWH also had lower vBMD at the spine and hip. In fully adjusted models, HIV independently predicted reduced aBMD at the lumbar spine, total hip, femoral neck, and ultradistal radius; menopausal stage remained a significant predictor of lumbar spine and ultradistal radius aBMD. CONCLUSIONS: HIV infection and menopausal stage were independent predictors of lower BMD, and had an additive effect on lumbar spine and total hip BMD. Additional research is needed to better understand underlying mechanisms by which HIV impacts BMD as women age and transition through menopause, and develop strategies to mitigate osteoporosis and fracture risk in this growing population.
