RESUMO

BACKGROUND: Polyclonal convalescent plasma may be obtained from donors who have recovered from coronavirus disease 2019 (Covid-19). The efficacy of this plasma in preventing serious complications in outpatients with recent-onset Covid-19 is uncertain. METHODS: In this multicenter, double-blind, randomized, controlled trial, we evaluated the efficacy and safety of Covid-19 convalescent plasma, as compared with control plasma, in symptomatic adults (≥18 years of age) who had tested positive for severe acute respiratory syndrome coronavirus 2, regardless of their risk factors for disease progression or vaccination status. Participants were enrolled within 8 days after symptom onset and received a transfusion within 1 day after randomization. The primary outcome was Covid-19-related hospitalization within 28 days after transfusion. RESULTS: Participants were enrolled from June 3, 2020, through October 1, 2021. A total of 1225 participants underwent randomization, and 1181 received a transfusion. In the prespecified modified intention-to-treat analysis that included only participants who received a transfusion, the primary outcome occurred in 17 of 592 participants (2.9%) who received convalescent plasma and 37 of 589 participants (6.3%) who received control plasma (absolute risk reduction, 3.4 percentage points; 95% confidence interval, 1.0 to 5.8; P = 0.005), which corresponded to a relative risk reduction of 54%. Evidence of efficacy in vaccinated participants cannot be inferred from these data because 53 of the 54 participants with Covid-19 who were hospitalized were unvaccinated and 1 participant was partially vaccinated. A total of 16 grade 3 or 4 adverse events (7 in the convalescent-plasma group and 9 in the control-plasma group) occurred in participants who were not hospitalized. CONCLUSIONS: In participants with Covid-19, most of whom were unvaccinated, the administration of convalescent plasma within 9 days after the onset of symptoms reduced the risk of disease progression leading to hospitalization.

RESUMO

Within-host HIV populations continually diversify during untreated infection, and this diversity persists within infected cell reservoirs during antiretroviral therapy (ART). Achieving a better understanding of on-ART proviral evolutionary dynamics, and a better appreciation of how the overall persisting pool of (largely genetically defective) proviruses differs from the much smaller replication-competent HIV reservoir, is critical to HIV cure efforts. We reconstructed within-host HIV evolutionary histories in blood from seven participants of the Women's Interagency HIV Study who experienced HIV seroconversion, and used these data to characterize the diversity, lineage origins, and ages of proviral env-gp120 sequences sampled longitudinally up to 12 years on ART. We also studied HIV sequences emerging from the reservoir in two participants. We observed that proviral clonality generally increased over time on ART, with clones frequently persisting long term. While on-ART proviral integration dates generally spanned the duration of untreated infection, HIV emerging in plasma was exclusively younger (i.e., dated to the years immediately pre-ART). The genetic and age distributions of distinct proviral sequences remained stable during ART in all but one participant, in whom there was evidence that younger proviruses had been preferentially eliminated after 12 years on ART. Analysis of the gag region in three participants corroborated our env-gp120-based observations, indicating that our observations are not influenced by the HIV region studied. Our results underscore the remarkable genetic stability of the distinct proviral sequences that persist in blood during ART. Our results also suggest that the replication-competent HIV reservoir is a genetically restricted, younger subset of this overall proviral pool.IMPORTANCECharacterizing the genetically diverse HIV sequences that persist in the reservoir despite antiretroviral therapy (ART) is critical to cure efforts. Our observations confirm that proviruses persisting in blood on ART, which are largely genetically defective, broadly reflect the extent of within-host HIV evolution pre-ART. Moreover, on-ART clonal expansion is not appreciably accompanied by the loss of distinct proviral lineages. In fact, on-ART proviral genetic composition remained stable in all but one participant, in whom, after 12 years on ART, proviruses dating to around near ART initiation had been preferentially eliminated. We also identified recombinant proviruses between parental sequence fragments of different ages. Though rare, such sequences suggest that reservoir cells can be superinfected with HIV from another infection era. Overall, our finding that the replication-competent reservoir in blood is a genetically restricted, younger subset of all persisting proviruses suggests that HIV cure strategies will need to eliminate a reservoir that differs in key respects from the overall proviral pool.

RESUMO

INTRODUCTION: People living with the human immunodeficiency virus (PWH) have microvascular disease. Since perivascular adipose tissue (PVAT) regulates microvascular function and adipose tissue is inflamed in PWH, we tested the hypothesis that PWH have inflamed PVAT that impairs the function of their small vessels. METHODS: Subcutaneous small arteries were dissected with or without (+ or -) PVAT from a gluteal skin biopsy from 11 women with treated HIV (WWH) aged < 50 years and 10 matched women without HIV and studied on isometric myographs. Nitric oxide (NO) and reactive oxygen species (ROS) were measured by fluorescence microscopy. Adipokines and markers of inflammation and ROS were assayed in PVAT. RESULTS: PVAT surrounding the small arteries in control women significantly (P < 0.05) enhanced acetylcholine (Ach)-induced endothelium dependent relaxation and NO and reduced contractions to thromboxane and endothelin-1. However, these effects of PVAT were reduced significantly (P < 0.05) in WWH whose PVAT released less adiponectin but more markers of ROS and inflammation. Moderation of contractions by PVAT were correlated positively with adipose adiponectin. CONCLUSION: PVAT from WWH has oxidative stress, inflammation and reduced release of adiponectin that may contribute to enhanced contractions and therefore could promote small artery dysfunction.

RESUMO

The menopausal transition is a pivotal time of cardiovascular risk, but knowledge is limited in HIV. We studied longitudinal carotid artery intima-media thickness (CIMT) in the Women's Interagency HIV Study (2004-2019; 979 women/3247 person-visits; 72% with HIV). Among women with HIV only, those who transitioned had greater age-related CIMT progression compared to those remaining premenopausal (difference in slope = 1.64 µm/year, P = .002); and CIMT increased over time in the pretransition (3.47 µm/year, P = .002) and during the menopausal transition (9.41 µm/year, P < .0001), but not posttransition (2.9 µm/year, P = .19). In women with HIV, menopause may accelerate subclinical atherosclerosis as measured by CIMT.

RESUMO

Among 103 reproductive-aged women with HIV in the U.S. South surveyed post-approval of long-acting injectable (LAI) cabotegravir/rilpivirine, nearly two-thirds reported willingness to try LAI antiretroviral therapy (ART). Most expressed preference for LAI over daily oral ART and had minimal concerns over potential LAI-ART use impacting reproductive health.

RESUMO

BACKGROUND: HIV and hepatitis C virus (HCV) are associated with increased risk of carotid artery atherosclerotic plaque and stroke. We examined associations of HIV- and HCV-related factors with echomorphologic features of carotid artery plaque. METHODS: This cross-sectional study included participants from the MACS (Multicenter AIDS Cohort Study)/WIHS (Women's Interagency HIV Study) Combined Cohort Study who underwent high-resolution B-mode carotid artery ultrasound. Plaques were characterized from 6 areas of the right carotid artery. Poisson regression controlling for demographic and cardiometabolic risk factors determined adjusted prevalence ratios (aPRs) and 95% CIs for associations of HIV- and HCV-related factors with echomorphologic features. RESULTS: Of 2655 participants (65% women, median age 44 [interquartile range, 37-50] years), 1845 (70%) were living with HIV, 600 (23%) were living with HCV, and 425 (16%) had carotid plaque. There were 191 plaques identified in 129 (11%) women with HIV, 51 plaques in 32 (7%) women without HIV, 248 plaques in 171 (28%) men with HIV, and 139 plaques in 93 (29%) men without HIV. Adjusted analyses showed that people with HIV and current CD4+ count <200 cells/µL had a significantly higher prevalence of predominantly echolucent plaque (aPR, 1.86 [95% CI, 1.08-3.21]) than those without HIV. HCV infection alone (aPR, 1.86 [95% CI, 1.08-3.19]) and HIV-HCV coinfection (aPR, 1.75 [95% CI, 1.10-2.78]) were each associated with higher prevalence of predominantly echogenic plaque. HIV-HCV coinfection was also associated with higher prevalence of smooth surface plaque (aPR, 2.75 [95% CI, 1.03-7.32]) compared with people without HIV and HCV. CONCLUSIONS: HIV with poor immunologic control, as well as HCV infection, either alone or in the presence of HIV, were associated with different echomorphologic phenotypes of carotid artery plaque.

RESUMO

BACKGROUND: Since 2000, there have been rising rates of syphilis infections nationally with higher incidence among minorities and persons living with human immunodeficiency virus (HIV) (PLWH). The purpose of this study was to determine syphilis treatment adequacy and factors associated with treatment delay. METHODS: This was a retrospective academic-public health collaboration with the District of Columbia Department of Public Health reviewing surveillance data of all primary, secondary, and early latent syphilis cases diagnosed between January 1, 2015, and December 31, 2019. Data were analyzed using multivariable logistic regression to identify factors associated with delayed treatment >14 days from diagnosis. RESULTS: Among 1852 individuals diagnosed with early syphilis, 93% (1730/1852) were male; 48% (893/1852) were coinfected with HIV; 43% (n = 796/1852) were African American/Black, 27% (n = 492/1852) were White, and race/ethnicity was unknown for 17% (n = 318/1852) of cases. Among 679 PLWH for whom viral load (VL) was known, 41% (278/679) had a VL < 20 copies/mL, and 18% (123/679) had VL >10,000 copies/mL. Treatment adequacy overall was 96.5%. Median time to syphilis treatment was 6 days (interquartile range = 4-7). Factors associated with delay of treatment included refused/unknown race (adjusted odds ratio [aOR], 1.95; 95% confidence interval [CI], 1.00-3.79), and HIV VL > 10,000 copies/mL (aOR, 1.97; 95% CI, 1.08-3.58). CONCLUSIONS: The factors we identified associated with delayed treatment may reflect systemic factors contributing to the increased rates of infection among key populations. This highlights the importance of targeted public health efforts with the goal of reducing transmission of both HIV and syphilis.

RESUMO

BACKGROUND: The trajectory of liver fibrosis is not well understood in the contemporary era of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) therapy. METHODS: We assessed the Enhanced Liver Fibrosis (ELF) score, aspartate transaminase-to-platelet ratio index (APRI) and Fibrosis-4 (FIB-4) in 116 women with HIV/HCV coinfection over a 4-year period. Random-effects linear regression models examined the rate of fibrosis change 1-2 years before starting HCV treatment, within 1 year before starting (peri-HCV treatment), within 1 year after and 1-2 years post-HCV treatment in unadjusted and adjusted models including age, race, and changes from pretreatment of factors that might affect fibrosis (eg, alcohol, integrase strand inhibitor [INSTI] use, waist circumference, CD4 count). RESULTS: INSTI use nearly doubled from pre- to peri-HCV treatment. In unadjusted analysis, there was a 3.3% rate of rise in ELF pre-HCV treatment, 2.2% and 3.6% rate of decline during the peri- and 1-year post-HCV treatment period, respectively, followed by a 0.3% rise. Similar findings were observed for APRI and FIB-4. There was little effect on the estimated fibrosis trajectories after adjustment. CONCLUSIONS: The apparent lack of decline in biomarkers of liver fibrosis beyond 1 year after HCV cure suggests that continued monitoring of liver fibrosis and interventions to mitigate progression in people with HIV after HCV cure remains essential.

RESUMO

BACKGROUND: Reduced plasma vitamin C (vitC) concentrations in human immunodeficiency virus (HIV) may result from abnormal urinary excretion: a renal leak. VitC renal leak indicates underlying nutritional dysregulation independent of diet. We hypothesized that increased renal leak prevalence in HIV would be associated with deficient vitC concentrations. METHODS: We conducted an outpatient cross-sectional study of 96 women (40 HIV [PWH] and 56 without HIV [PWOH]) at the National Institutes of Health and Georgetown University. Renal leak was defined as abnormal urinary vitC excretion at fasting plasma concentrations <43.2µM, 2 SDs below vitC renal threshold in healthy women. To determine the primary outcome of renal leak prevalence, matched urine and plasma samples were collected the morning after overnight fast. Secondary outcomes assessed group differences in mean plasma vitC concentrations and prevalence of vitC deficiency. Exploratory outcomes assessed clinical parameters associated with renal leak. VitC was measured by high-performance liquid chromatography with coulometric electrochemical detection. RESULTS: PWH had significantly higher renal leak prevalence (73%vs14%; OR (odds ratio):16; P<.001), lower mean plasma vitC concentrations (14µMvs50µM; P<.001), and higher prevalence of vitC deficiency (43%vs7%; OR:10; P<.001) compared with PWOH, unchanged by adjustments for confounding factors. Significant predictors of renal leak included antiretroviral therapy (ART), Black race, older age, and metabolic comorbidities but not viral load or CD4 count. When compared with other chronic disease cohorts, PWH had the highest prevalence of renal leak and vitC deficiency (P<.001). CONCLUSIONS: High prevalence of vitC renal leak in HIV was associated with vitC deficiency, ART use, and race/ethnicity differences.

RESUMO

Menopause may impact the earlier onset of aging-related comorbidities among women with versus without human immunodeficiency virus (HIV). We found that menopausal status, age, and HIV were independently associated with higher comorbidity burden, and that HIV impacted burden most in the pre-/perimenopausal phases.

RESUMO

BACKGROUND: People with human immunodeficiency virus (HIV) have been reported to have increased risk of clinical and subclinical cardiovascular disease. Existing studies have focused on men and often have been uncontrolled or lacked adequate HIV-negative comparators. METHODS: We performed echocardiography in the Women's Interagency HIV Study to investigate associations of HIV and HIV-specific factors with cardiac phenotypes, including left ventricular systolic dysfunction (LVSD), isolated LV diastolic dysfunction (LVDD), left atrial enlargement (LAE), LV hypertrophy (LVH), and increased tricuspid regurgitation velocity (TRV). RESULTS: Of 1654 participants (age 51 ± 9 years), 70% had HIV. Sixty-three (5.4%) women with HIV (WWH) had LVSD; 71 (6.5%) had isolated LVDD. Compared with women without HIV (WWOH), WWH had a near-significantly increased risk of LVSD (adjusted relative risk = 1.69; 95% confidence interval = 1.00 to 2.86; P = .051). No significant association was noted for HIV seropositivity with other phenotypes, but there was a risk gradient for decreasing CD4+ count among WWH that approached or reached significance for isolated LVDD, LAE, and LVH. WWH with CD4+ count <200 cells/mm3 had significantly higher prevalence of LAE, LVH, and high TRV than WWOH. There were no consistent associations for viral suppression or antiretroviral drug exposure. CONCLUSIONS: This study suggests that WWH have a higher risk of LVSD compared with sociodemographically similar WWOH, but their risk for isolated LVDD, LAE, LVH, and high TRV is increased only with reduced CD4+ count. Although these findings warrant replication, they support the importance of cardiovascular risk-factor and HIV-disease control for heart disease prevention in this population.

RESUMO

BACKGROUND: The efficacy of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) convalescent plasma (CCP) for preventing infection in exposed, uninfected individuals is unknown. CCP might prevent infection when administered before symptoms or laboratory evidence of infection. METHODS: This double-blinded, phase 2 randomized, controlled trial (RCT) compared the efficacy and safety of prophylactic high titer (≥1:320 by Euroimmun ELISA) CCP with standard plasma. Asymptomatic participants aged ≥18 years with close contact exposure to a person with confirmed coronavirus disease 2019 (COVID-19) in the previous 120 hours and negative SARS-CoV-2 test within 24 hours before transfusion were eligible. The primary outcome was new SARS-CoV-2 infection. RESULTS: In total, 180 participants were enrolled; 87 were assigned to CCP and 93 to control plasma, and 170 transfused at 19 sites across the United States from June 2020 to March 2021. Two were excluded for screening SARS-CoV-2 reverse transcription polymerase chain reaction (RT-PCR) positivity. Of the remaining 168 participants, 12/81 (14.8%) CCP and 13/87 (14.9%) control recipients developed SARS-CoV-2 infection; 6 (7.4%) CCP and 7 (8%) control recipients developed COVID-19 (infection with symptoms). There were no COVID-19-related hospitalizations in CCP and 2 in control recipients. Efficacy by restricted mean infection free time (RMIFT) by 28 days for all SARS-CoV-2 infections (25.3 vs 25.2 days; P = .49) and COVID-19 (26.3 vs 25.9 days; P = .35) was similar for both groups. CONCLUSIONS: Administration of high-titer CCP as post-exposure prophylaxis, although appearing safe, did not prevent SARS-CoV-2 infection. CLINICAL TRIALS REGISTRATION: NCT04323800.

RESUMO

• Human immunodeficiency virus (HIV) drug resistance has implications for antiretroviral treatment strategies and for containing the HIV pandemic because the development of HIV drug resistance leads to the requirement for antiretroviral drugs that may be less effective, less well-tolerated, and more expensive than those used in first-line regimens. • HIV drug resistance studies are designed to determine which HIV mutations are selected by antiretroviral drugs and, in turn, how these mutations affect antiretroviral drug susceptibility and response to future antiretroviral treatment regimens. • Such studies collectively form a vital knowledge base essential for monitoring global HIV drug resistance trends, interpreting HIV genotypic tests, and updating HIV treatment guidelines. • Although HIV drug resistance data are collected in many studies, such data are often not publicly shared, prompting the need to recommend best practices to encourage and standardize HIV drug resistance data sharing. • In contrast to other viruses, sharing HIV sequences from phylogenetic studies of transmission dynamics requires additional precautions as HIV transmission is criminalized in many countries and regions. • Our recommendations are designed to ensure that the data that contribute to HIV drug resistance knowledge will be available without undue hardship to those publishing HIV drug resistance studies and without risk to people living with HIV.

RESUMO

BACKGROUND: COVID-19 convalescent plasma (CCP) is an important therapeutic option for outpatients at high risk of hospitalization from SARS-CoV-2 infection. We assessed the safety of outpatient CCP transfusions administered during clinical trials. STUDY DESIGN AND METHODS: We analyzed data pertaining to transfusion-related reactions from two randomized controlled trials in the U.S. that evaluated the efficacy of CCP versus control plasma in various ambulatory settings. Multivariable logistic regression was used to assess whether CCP was associated with transfusion reactions, after adjusting for potential confounders. RESULTS: The combined study reported 79/1351 (5.9%) adverse events during the transfusion visit, with the majority 62/1351 (4.6%) characterized by mild, allergic-type findings of urticaria, and/or pruritus consistent with minor allergic transfusion reactions; the other reported events were attributed to the patients' underlying disease, COVID-19, or vasovagal in nature. We found no difference in the likelihood of allergic transfusion reactions between those receiving CCP versus control plasma (adjusted odds ratio [AOR], 0.75; 95% CI, 0.43-1.31). Risk of urticaria and/or pruritus increased with a pre-existing diagnosis of asthma (AOR, 2.33; 95% CI, 1.16-4.67). We did not observe any CCP-attributed antibody disease enhancement in participants with COVID-19 or increased risk of infection. There were no life-threatening severe transfusion reactions and no patients required hospitalization related to transfusion-associated complications. DISCUSSION: Outpatient plasma administration was safely performed for nearly 1400 participants. CCP is a safe therapeutic option for outpatients at risk of hospitalization from COVID-19.

RESUMO

BACKGROUND: Alterations in gut microbiota and blood metabolomic profiles have been implicated in HIV infection and cardiovascular disease. However, it remains unclear whether alterations in gut microbiota may contribute to disrupted host blood metabolomic profiles in relation to atherosclerosis, especially in the context of HIV infection. METHODS: We analyzed cross-sectional associations between gut microbiota features and carotid artery plaque in 361 women with or at high risk of HIV (67% HIV+), and further integrated plaque-associated microbial features with plasma lipidomic/metabolomic profiles. Furthermore, in 737 women and men, we examined prospective associations of baseline gut bacteria-associated lipidomic and metabolomic profiles with incident carotid artery plaque over 7-year follow-up. RESULTS: We found 2 potentially pathogenic bacteria, Fusobacterium and Proteus, were associated with carotid artery plaque; while the beneficial butyrate producer Odoribacter was inversely associated with plaque. Fusobacterium and Proteus were associated with multiple lipids/metabolites which were clustered into 8 modules in network. A module comprised of 9 lysophosphatidylcholines and lysophosphatidylethanolamines and a module comprised of 9 diglycerides were associated with increased risk of carotid artery plaque (risk ratio [95% CI], 1.34 [1.09-1.64] and 1.24 [1.02-1.51] per SD increment, respectively). Functional analyses identified bacterial enzymes in lipid metabolism associated with these plasma lipids. In particular, phospholipase A1 and A2 are the key enzymes in the reactions producing lysophosphatidylcholines and lysophosphatidylethanolamines. CONCLUSIONS: Among individuals with or at high risk of HIV infection, we identified altered gut microbiota and related functional capacities in the lipid metabolism associated with disrupted plasma lipidomic profiles and carotid artery atherosclerosis.

RESUMO

OBJECTIVE: To evaluate the associations of HIV infection with preterm birth (PTB), and of HIV antiretroviral therapy (ART) with PTB. METHODS: We analysed singleton live-born pregnancies among women from 1995 to 2019 in the Women's Interagency HIV Study, a prospective cohort of US women with, or at risk for, HIV. The primary exposures were HIV status and ART use before delivery [none, monotherapy or dual therapy, or highly active antiretroviral therapy (HAART)]. The primary outcome was PTB < 34 weeks, and, secondarily, < 28 and < 37 weeks. We analysed self-reported birth data, and separately modelled the associations between HIV and PTB, and between ART and PTB, among women with HIV. We used modified Poisson regression, and adjusted for age, race, parity, tobacco use and delivery year, and, when modelling the impact of ART, duration from HIV diagnosis to delivery, nadir CD4 count, and pre-pregnancy viral load and CD4 count. RESULTS: We analysed 488 singleton deliveries (56% exposed to HIV) to 383 women. The risk of PTB < 34 weeks was similar among women with and without HIV, but the risk of PTB < 37 weeks was higher [32% vs. 23%; adjusted risk ratio (aRR) = 1.43; 95% confidence interval (CI): 1.07-1.91] among women with HIV. The risk of PTB < 34 weeks was lower among women with HIV receiving HAART than among those receiving no ART (7% vs. 26%; aRR:0.19; 95% CI: 0.08-0.44). The associations between HAART and PTB < 28 and < 37 weeks were similar. CONCLUSIONS: Antiretroviral therapy exposure was associated with a decreased risk of PTB among a US cohort of women with HIV. Given the growing concerns about ART and adverse pregnancy outcomes, this finding that ART may be protective for PTB is reassuring.

RESUMO

OBJECTIVE: Syphilis rates among women in the USA more than doubled between 2014 and 2018. We sought to identify correlates of syphilis among women enrolled in the Women's Interagency HIV Study (WIHS) to inform targeted interventions. METHODS: The retrospective cross-sectional analysis of secondary data included women with HIV or at-risk of HIV who enrolled in the multisite US WIHS cohort between 1994 and 2015. Syphilis screening was performed at baseline. Infection was defined serologically by a positive rapid plasma reagin test with confirmatory treponemal antibodies. Sociodemographic and behavioural characteristics stratified by baseline syphilis status were compared for women enrolled during early (1994-2002) and recent (2011-2015) years. Multivariable binomial modelling with backward selection (p>0.2 for removal) was used to model correlates of syphilis. RESULTS: The study included 3692 women in the early cohort and 1182 women in the recent cohort. Syphilis prevalence at enrolment was 7.5% and 3.7% in each cohort, respectively (p<0.01). In adjusted models for the early cohort, factors associated with syphilis included age, black race, low income, hepatitis C seropositivity, drug use, HIV infection and >100 lifetime sex partners (all p<0.05). In the recent cohort, age (adjusted prevalence OR (aPOR) 0.2, 95% CI 0.1 to 0.6 for 30-39 years; aPOR 0.5, 95% CI 0.2 to 1.0 for 40-49 years vs ≥50 years), hepatitis C seropositivity (aPOR 2.1, 95% CI 1.0 to 4.1) and problem alcohol use (aPOR 2.2, 95% CI 1.1 to 4.4) were associated with infection. CONCLUSIONS: Syphilis screening is critical for women with HIV and at-risk of HIV. Targeted prevention efforts should focus on women with hepatitis C and problem alcohol use.

RESUMO

Convalescent plasma, collected from donors who have recovered from a pathogen of interest, has been used to treat infectious diseases, particularly in times of outbreak, when alternative therapies were unavailable. The COVID-19 pandemic revived interest in the use of convalescent plasma. Large observational studies and clinical trials that were executed during the pandemic provided insight into how to use convalescent plasma, whereby high levels of antibodies against the pathogen of interest and administration early within the time course of the disease are critical for optimal therapeutic effect. Several studies have shown outpatient administration of COVID-19 convalescent plasma (CCP) to be both safe and effective, preventing clinical progression in patients when administered within the first week of COVID-19. The United States Food and Drug Administration expanded its emergency use authorization (EUA) to allow for the administration of CCP in an outpatient setting in December 2021, at least for immunocompromised patients or those on immunosuppressive therapy. Outpatient transfusion of CCP and infusion of monoclonal antibody therapies for a highly transmissible infectious disease introduces nuanced challenges related to infection prevention. Drawing on our experiences with the clinical and research use of CCP, we describe the logistical considerations and workflow spanning procurement of qualified products, infrastructure, staffing, transfusion, and associated management of adverse events. The purpose of this description is to facilitate the efforts of others intent on establishing outpatient transfusion programs for CCP and other antibody-based therapies.

RESUMO

Social support is associated with improved HIV care and quality of life. We utilized latent class analysis to identify three classes of baseline emotional and tangible perceived social support, termed "Strong", "Wavering" and "Weak". "Weak" vs. "Strong" perceived social support was associated over time with an 8% decreased risk of optimal antiretroviral therapy (ART) adherence for emotional and 6% decreased risk for tangible perceived social support. Importantly, "Wavering" vs "Strong" social support also showed a decreased risk of ART adherence of 6% for emotional and 3% for tangible support. "Strong" vs. "Weak" perceived support had a similar association with undetectable viral load, but the association for "Strong" vs. "Wavering" support was not statistically significant. Intensity of social support is associated with HIV care outcomes, and strong social support may be needed for some individuals. It is important to quantify the level or intensity of social support that is needed to optimize HIV outcomes.


RESUMEN: El apoyo social está asociado con una mejor atención y calidad de vida del virus de inmunodeficiencia humana (VIH). Utilizamos el análisis de clase latente para identificar tres clases de apoyo social percibido emocional y tangible de referencia, denominado "fuerte", "vacilante" y "débil". El apoyo social percibido "débil" versus el "fuerte" se asoció con el tiempo con una disminución del 8% en el riesgo de una adherencia óptima al terapia antirretroviral (TAR) para el apoyo emocional y del 6% en el riesgo de un apoyo social percibido tangible. Es importante destacar que el apoyo social "vacilante" frente a "fuerte" también mostró una disminución del riesgo de adherencia al TAR del 6% para el apoyo emocional y del 3% para el apoyo tangible. El apoyo percibido "fuerte" frente a "débil" tuvo una asociación similar con una carga viral indetectable, pero la asociación entre el apoyo "fuerte" y el apoyo "vacilante" no fue estadísticamente significativa. La intensidad del apoyo social está asociada con los resultados de la atención del VIH, y algunas personas pueden necesitar un fuerte apoyo social. Es importante cuantificar el nivel o la intensidad del apoyo social que se necesita para optimizar los resultados del VIH.

RESUMO

BACKGROUND: Human immunodeficiency virus (HIV) infection may accelerate development of aging-related non-AIDS comorbidities (NACMs). The incidence of NACMs is poorly characterized among women living with HIV (WLWH). METHODS: WLWH and HIV-seronegative participants followed in the Women's Interagency HIV Study (WIHS) through 2009 (when >80% of WLWH used antiretroviral therapy) or onward were included, with outcomes measured through 31 March 2018. Sociodemographics, clinical covariates, and prevalent NACM were determined at enrollment. We used Poisson regression models to determine incident NACM burden (number of NACMs accrued through most recent WIHS visit out of 10 total NACMs assessed) by HIV serostatus and age. RESULTS: There were 3129 participants (2239 WLWH, 890 HIV seronegative) with 36 589 person-years of follow-up. At enrollment, median age was 37 years, 65% were black, and 47% currently smoked. In fully adjusted analyses, WLWH had a higher incident NACM rate compared with HIV-seronegative women (incidence rate ratio, 1.36 [95% confidence interval (CI), 1.02-1.81]). Incident NACM burden was higher among WLWH vs HIV-seronegative women in most age strata (HIV × age interaction: P = .0438), and women <25 years old had the greatest incidence rate ratio by HIV serostatus at 1.48 (95% CI, 1.19-1.84) compared with those in older age groups. Incident NACM burden was associated with traditional comorbidity risk factors but not HIV-specific indices. CONCLUSIONS: Incident NACM burden was higher among WLWH than HIV-seronegative women. This difference was most dramatic among women aged <25 years, a group for whom routine comorbidity screening is not prioritized. Established non-HIV comorbidity risk factors were significantly associated with incident NACM burden. More data are needed to inform best practices for NACM screening, prevention, and management among WLWH, particularly young women.
