Morrison, Susan Michaels-Strasser After a decade of civil war and the 2014–2016 West African Ebola outbreak, Sierra Leone now faces the COVID-19 pandemic with a fragile health system. As was demonstrated during Ebola, preparedness is key to limiting a health crisis’ spread and impact on health systems and ensuring continued care for vulnerable populations including people living with HIV (PLHIV). To assess COVID-19 preparedness and inform interventions to ensure continuity of HIV services at health facilities (HFs) and community service points (CSPs), we conducted site readiness assessments in Freetown, the epicenter of COVID-19 in Sierra Leone. Data were collected at nine high-volume HIV HFs and seven CSPs in April 2020, a month after COVID-19 was declared a pandemic. CSPs comprised three community drop-in centers providing HIV counseling and testing services as well as HIV prevention services (e.g., condoms and lubricants) for key and priority populations and four community-based support groups serving PLHIV. At the time of assessment, CSPs did not provide antiretroviral therapy (ART) but were considered potential sites for expansion of differentiated service delivery (DSD)—a client-centered approach to HIV care—in the context of COVID-19. Overall, 5/9 HFs had trained staff on use of personal protective equipment (PPE) and prevention of COVID-19 transmission. Most had access to masks (5/9) and gloves (7/9) for management of suspected/confirmed COVID-19 cases, and 4/9 HFs had triage procedures for isolation of suspected cases. Conversely, few CSPs had access to masks (2/7) or gloves (2/7) and no staff were trained on PPE use or COVID-19 transmission. 7/9 HFs had adequate ART stock for multi-month dispensing though few had procedures for (3/9) or had trained staff in providing DSD (2/9). Among CSPs where measures were applicable, 2/4 had procedures for DSD, 1/3 had staff trained on DSD and none had adequate ART stock. Identification of gaps in COVID-19 preparedness is a critical step in providing support for infection control and modified service delivery. Findings from this assessment highlight gaps in COVID-19 preparedness measures at sites supporting PLHIV in Sierra Leone and indicate CSPs may require intensive supervision and training to ensure HIV services are uninterrupted while minimizing COVID-19 risk, especially if used as sites to scale up DSD.

by Dani Zoorob, Shivam Shah, Danielle La Saevig, Courtney Murphy, Shaza Aouthmany, Kris Brickman Background Acute augmentation of stress and disruption of training, such as during the COVID-19 pandemic, may impact resident wellbeing. Objectives We investigated how residents in various specialties in the United States were impacted by COVID-19 on mental wellbeing and resilience levels, and the methodology for coping with the stress incurred. Methods In April 2020, the authors electronically surveyed 200 residency programs of all specialties nationally. The survey utilized two validated questionnaires to assess wellbeing and resilience, while investigating demographics and coping mechanisms. The authors used student t-test and ANOVA to quantitatively analyze the data. Results The sample consisted of 1115 respondents (with an 18% response rate). Male gender & Age >39 years were associated with more favorable average well-being indices (both p<0.01). Regarding resources, institutional support (IS) appeared favorable for resident well-being (IS 2.74, SD1.96 vs NoIS 3.71, SD2.29, p<0.01) & resilience (IS 3.72, SD0.70 vs NoIS 3.53, SD0.73, p = 0.05). The effects of mindfulness practices (MP) were not statistically significant for improvement of wellness (MP 2.87, SD 1.99 vs No MP 2.76, SD 2.15, p = 0.85) or resilience (MP 3.71, SD 0.70 vs No MP 3.72, SD 0.68, p = 0.87). Conclusions Findings highlight the critical importance of resident mental status in cases of augmented stress situations. Institutional support may contribute to promotion of resident wellbeing.

Lacticaseibacillus rhamnosus GR-1 (LGR-1) (previously classified as Lactobacillus rhamnosus GR-1) is the most researched probiotic strain for women’s health. Its various urogenital health effects, including a reduction in the recurrence of bacterial vaginosis and urinary-tract infection, are well documented. The strain has also been safely used by HIV-positive subjects, a portion of whom have reported reduced diarrhea and increased CD4 counts. Unlike most probiotic strains used for urogenital health, LGR-1 has been extensively studied for its properties, including its genomic and metabolic traits and its surface properties.

by Selamawit Woldesenbet, Tendesayi Kufa-Chakezha, Carl Lombard, Samuel Manda, Mireille Cheyip, Kassahun Ayalew, Brian Chirombo, Peter Barron, Karidia Diallo, Bharat Parekh, Adrian Puren Introduction New HIV infection during pre-conception and pregnancy is a significant contributor of mother–to–child transmission of HIV in South Africa. This study estimated HIV incidence (defined as new infection within the last one year from the time of the survey which included both new infections occurred during pregnancy or just before pregnancy) among pregnant women and described the characteristics of recently infected pregnant women at national level. Methods Between 1 October and 15 November 2017, we conducted a national cross–sectional survey among pregnant women aged 15–49 years old attending antenatal care at 1,595 public facilities. Blood specimens were collected from pregnant women and tested for HIV in a centralised laboratory. Plasma viral load and Limiting Antigen Avidity Enzyme Immunosorbent Assay (LAg) tests were further performed on HIV positive specimens to differentiate between recent and long–term infections. Recent infection was defined as infection that occurred within one year from the date of collection of blood specimen for the survey. Data on age, age of partner, and marital status were collected through interviews. Women whose specimens were classified as recent by LAg assay and with viral loads >1,000 copies/mL were considered as recently infected. The calculated proportion of HIV positive women with recent infection was adjusted for assay–specific parameters to estimate annual incidence. Survey multinomial logistic regression was used to examine factors associated with being recently infected using HIV negative women as a reference group. Age–disparate relationship was defined as having a partner 5 or more years older. Results Of 10,049 HIV positive participants with LAg and viral load data, 1.4% (136) were identified as recently infected. The annual HIV incidence was 1.5% (95% confidence interval (CI): 1.2–1.7). In multivariable analyses, being single (adjusted odds ratio, aOR: 3.4, 95% CI: 1.8–6.2) or cohabiting (aOR: 3.8, 95% CI: 1.8–7.7), compared to being married as well as being in an age–disparate relationship among young women (aOR: 3.1, 95% CI: 2.0–4.7; reference group: young women (15–24years) whose partners were not 5 years or more older) were associated with higher odds of recent infection. Conclusions Compared to previous studies among pregnant women, the incidence estimated in this study was substantially lower. However, the UNAIDS target to reduce incidence by 75% by 2020 (which is equivalent to reducing incidence to…

Particle sorting is a fundamental method in various fields of medical and biological research. However, existing sorting applications are not capable for high-throughput sorting of large-size (>100 micrometers) particles. Here, we present a novel on-chip sorting method using traveling vortices generated by on-demand microjet flows, which locally exceed laminar flow condition, allowing for high-throughput sorting (5 kilohertz) with a record-wide sorting area of 520 micrometers. Using an activation system based on fluorescence detection, the method successfully sorted 160-micrometer microbeads and purified fossil pollen (maximum dimension around 170 micrometers) from lake sediments. Radiocarbon dates of sorting-derived fossil pollen concentrates proved accurate, demonstrating the method’s ability to enhance building chronologies for paleoenvironmental records from sedimentary archives. The method is capable to cover urgent needs for high-throughput large-particle sorting in genomics, metabolomics, and regenerative medicine and opens up new opportunities for the use of pollen and other microfossils in geochronology, paleoecology, and paleoclimatology.

Objective: To describe the pharmacokinetics (PK), safety, and efficacy of etravirine (ETR) in HIV-infected children 1 to < 6 yrs. Design: Phase I/II, open label, multicenter, dose-finding study. Methods: Antiretroviral (ARV)-experienced children in two age cohorts (I: 2-…

Objective: To evaluate associations between hair antiretroviral (ARV) hair concentrations as an objective, cumulative adherence metric, with self-reported adherence and virologic outcomes. Design: Analysis of cohort A of the ACTG-A5288 study. These patients in resource-limited settings were failing second-line PI-based ART, but were susceptible to ≥1 NRTI and their PI, and continued taking their PI-based regimen. Methods: ARV hair concentrations participants taking 2 NRTIs with boosted atazanavir (n = 69) or lopinavir (n = 112) were analyzed at weeks 12, 24, 36 and 48 using liquid-chromatography-tandem-mass-spectrometry assays. Participants self-reported percentage of doses taken in the previous month; virologic failure (VF) was confirmed HIV-1 RNA≥1000 copies/mL at week 24 or 48. Results: From 181 participants with hair samples, (61% female median age: 39y; CD4 count: 167 cells/uL; HIV-1 RNA: 18,648 copies/mL), 91 (50%) experienced VF at either visit. At 24 weeks, median hair concentrations were 2.95 (IQR 0.49–4.60) ng/mg for atazanavir, 2.64 (IQR 0.73-7.16) for lopinavir, and 0.44 (IQR 0.11-0.76) for ritonavir. Plasma HIV-1 RNA demonstrated inverse correlations with hair levels (rs −0.46 to −0.74) at weeks 24 and 48. Weaker associations were seen with self-reported adherence (rs −0.03 to −0.24). Decreasing hair concentrations were significantly associated with VF, the hazard ratio (HR) (95%CI) for ATV, LPV and RTV were 0.69 (0.56-0.86), 0.77 (0.68–0.87), and 0.12 (0.06–0.27) respectively. Conclusions: PI hair concentrations showed stronger associations with subsequent virologic outcomes than self-reported adherence in this cohort. Hair adherence measures could identify individuals at risk of 2nd-line treatment failure in need of interventions.

Objective: Previous studies indicate that transmitted/founder HIV-1 isolates are sensitive to neutralization by the transmitting donor's antibodies. This is true in at least a subset of sexual transmissions. We investigated whether this selection for neutralization-sensitive variants begins in the genital tract of the donor, prior to transmission. Design: Laboratory study. Methods: HIV-1 viruses from semen and blood of two male donors living with HIV-1 were tested for neutralization sensitivity to contemporaneous autologous antibodies. Results: In one donor, semen-derived clones (n = 10, geometric mean ID50 = 176) were 1.75 fold (95%CI 1.11–2.76, p = 0.018) more sensitive than blood-derived clones (n = 12, geometric mean ID50 = 111) to the individual's own contemporaneous neutralizing antibodies. Enhanced overall neutralization sensitivity of the semen-derived clones could not explain the difference because these semen-derived isolates showed a trend of being less sensitive to neutralization by a pool of heterologous clade-matched sera. This relative sensitivity of semen-derived clones was not observed in a second donor who did not exhibit obvious independent HIV-1 replication in the genital tract. A Bayesian analysis suggested that the set of semen sequences that we analysed originated from a blood sequence. Conclusions: In some instances, selection for neutralization sensitive variants during HIV-1 transmission begins in the genital tract of the donor and this may be driven by independent HIV-1 replication in this compartment. Thus, a shift in the selective milieu in the male genital tract allows outgrowth of neutralization-sensitive HIV-1 variants, shaping the population of isolates available for transmission to a new host.

Objectives: People living with HIV are exposed to a higher risk of coronary artery disease (CAD) compared to the general population. Epicardial fat may play a unique role in promoting coronary atherosclerosis. We measured epicardial fat in participants living with HIV and controls and investigated its association with coronary plaque volume and low attenuation plaque, a marker of plaque vulnerability. Design: This is a cross sectional study, nested in the Canadian HIV and Aging Cohort Study, a large prospective cohort actively following participants with HIV and controls. Participants with low/intermediate cardiovascular risk without symptoms/history of CAD were invited to undergo cardiac computed tomography (CT). Methods: Volume of epicardial fat, coronary plaque and low attenuation component of the plaque were measured. Association between epicardial fat, coronary plaque volume and low attenuation component was tested using adjusted regression analysis. Results: A total of 169 participants with HIV and 81 controls underwent cardiac CT. Participants with HIV had a greater epicardial fat volume compared to controls (p = 0.019). In participants with HIV, epicardial fat volume was positively associated with duration of non-nucleoside reverse transcriptase inhibitors (NNRTI) (β=2.19, p = 0.004). After adjustment for cardiovascular risk factors, epicardial fat volume was positively associated to non-calcified plaque volume (OR = 1.09, p = 0.028) and to the low attenuation plaque component portion (β=0.38, p = 0.026). Conclusion: The association of epicardial fat volume to non-calcified plaque volume and to low attenuation component plaque may suggest a potential mechanism by which epicardial fat could be a silent driver of CAD in the HIV population.

Objectives: Gaps between recommended and actual levels of HIV preexposure prophylaxis (PrEP) use remain among men who have sex with men (MSM). Interventions can address these gaps, but it is unknown how public health initiatives should invest prevention funds into these interventions to maximize their population impact. Design: We used a stochastic network-based HIV transmission model for MSM in the Atlanta area paired with an economic budget optimization model. Methods: The model simulated MSM participating in up to three real-world PrEP cascade interventions designed to improve initiation, adherence, or persistence. The primary outcome was infections averted over 10 years. The budget optimization model identified the investment combination under different budgets that maximized this outcome given intervention costs from a payer perspective. Results: From the base 15% PrEP coverage level, the three interventions could increase coverage to 27%, resulting in 12.3% of infections averted over 10 years. Uptake of each intervention was interdependent: maximal use of the adherence and persistence interventions depended on new PrEP users generated by the initiation intervention. As the budget increased, optimal investment involved a mixture of the initiation and persistence interventions, but not the adherence intervention. If adherence intervention costs were halved, the optimal investment was roughly equal across interventions. Conclusions: Investments into the PrEP cascade through initiatives should account for the interactions of the interventions as they are collectively deployed. Given current intervention efficacy estimates, the total population impact of each intervention may be improved with greater total budgets or reduced intervention costs. Correspondence to Samuel M.

Objective: The objective of this study was to compare HIV-negative cisgender women (CGW) with MSM for mucosal tissue differences in pharmacokinetics, HIV infectivity and cell phenotype. Design: A substudy of HPTN 069/ACTG A5305, 48-week study of three oral candidate preexposure prophylaxis regimens: maraviroc, maraviroc/emtricitabine and maraviroc/tenofovir disoproxil fumarate (TDF) compared with a TDF/emtricitabine control group. Methods: Plasma, peripheral blood mononuclear cells and cervical and colorectal tissue biopsies were collected at Baseline (no drug), Week 24 and 48 (on drug), and Week 49 (1-week postdrug). Drug concentrations were assessed in all matrices. HIV infectivity was assessed using tissue biopsy ‘explants’ challenged with HIV ex vivo followed by HIV p24 measurement. Flow cytometry evaluated colorectal cell phenotype. Results: Thirty-seven CGW and 54 MSM participated. CGW's colorectal explant p24 was higher than MSM before (0.31 log10, P = 0.046), during (1.01-1.19 log10, P = 0.016) and one week after (0.61 log10, P = 0.011) study drug dosing. Pooling regimens, cervical explant p24 did not differ among visits. CGW had higher plasma maraviroc and colorectal tissue tenofovir diphosphate and lower colorectal tissue emtricitabine (all P …

Treatment with tenofovir disoproxil fumarate (TDF) has been associated with hypophosphatemia mainly due to injury of the renal proximal tubulus. Studies on the impact of tenfovir alafenamid (TAF) on phosphate homeostasis in PLHIV are limited. Prompted by a patient with phosphate wasting under tenofovir but no other evidence for tubular dysfunction, a retrospective cohort analysis with 102 people living with HIV (PLHIV) revealed that hypophosphatemia remained largely unchanged after switching from TDF to TAF.

Objective: People with HIV (PWH) experience increased prevalence of obstructive lung disease (OLD), regardless of greater observed smoking behaviors. We investigated whether the effect of incident OLD on mortality differed by HIV and HIV viral suppression among persons who inject drugs (PWID) and report smoking history. Design: ALIVE is a longitudinal, observational cohort study of HIV-positive and seronegative PWID. This analysis included participants who had at least one spirometry measure to assess OLD between 2007 and 2016, excluding those who never smoked (5%, n = 62) or had baseline OLD (17%, n = 269). Methods: Incident OLD occurred when the first pre-bronchodilator FEV1/FVC…

The Coronavirus disease 2019 (COVID-19) pandemic continues with 122.5 million cases and over 2.7 million deaths reported by the World Health Organization on the 23rd of March 2021(WHO, 2021). The virus has more impact onimmunocompromised patients such as cancer patients (Belsky, 2021, Jindal, 2020), stem cell transplant patients (Belsky, 2021, Sahu, 2020), HIV patients (Patel, 2021), solid organ transplant recipients (Belsky, 2021) including heart transplant patients (Marcondes-Braga, 2021). We present a case of COVID-19-related post-myocarditis state on MRI late after initial infection in a HT recipient.

Abstract Background Existing evidence showed that Human Immunodeficiency Virus counselling and testing uptake among Ethiopian youths is low, and factors contributing to it are not well studied. Therefore, this study aims to assess the status of uptake and identify its determinants using the 2016 Ethiopia Demographic and Health Survey data. Method Data of 10,903 Ethiopian youths were extracted from the 2016 Ethiopian Demographic and Health Survey. The association between the response variable and the predictors was modeled by multilevel binary logistic regression, whereas adjusted odds ratio and confidence intervals were used to measure associations and their statistical significance. The variation in the uptake of counselling and testing of HIV across regions of Ethiopia was quantified by intra-class correlation. Result The current study revealed that, overall, 34.9% (95% CI: 33.5, 36.2%) Ethiopian youths were ever tested for human immunodeficiency virus. Results show that about 9% of the variation in the probability of being tested for the disease was due to the regional variations. Moreover, having moderate and comprehensive HIV knowledge, being rich, having risky sexual behaviour, having a better educational level, having professional work, being married, owning of mobile, and having access to media were positively associated with human immunodeficiency virus voluntary counselling and testing uptake. On the other hand, being male, following protestant religion, following Muslim religion, and following other religions than orthodox religion were negatively associated with the uptake of human immunodeficiency virus counselling and testing. Conclusion Voluntary human immunodeficiency virus counselling and testing uptake among Ethiopian youths is very low and varies across the regions which might hamper the ambitious plan of Ethiopia to end the disease as a public health threat by 2030. Emphasis should be given to promoting the youths’ HIV-related knowledge through community-based education, encouraging and empowering the youths to participate in professional works by giving due focus to poor youths, and promoting mass media utilization to better achieve the plan.

Objective Youth represent a population disparately impacted by the HIV epidemic. With most new HIV diagnoses occurring among adolescents and young adults, novel approaches to address this disparity are necessary. The objective of the current study was to describe the Youth to Telehealth and Text to Improve Engagement in Care (Y2TEC) intervention, which aims to fill this gap. The Y2TEC intervention (trial registration NCT03681145) offers an innovative approach to improve HIV treatment engagement among youth living with HIV by focusing on treatment barriers related to mental health and substance use. This allows for a holistic approach to providing culturally informed intervention strategies for this population. Participants and setting The Y2TEC intervention was developed for youth with HIV in the large metropolitan area of the San Francisco Bay Area. The Y2TEC intervention was developed based on formative interdisciplinary research and is grounded in the information–motivation–behavioural skills model. Results The intervention includes 12 sessions each lasting 20–30 minutes, which are delivered through videoconferencing and accompanying bidirectional text messaging. The intervention sessions are individualised, with session dosage in each major content area determined by participant’s level of acuity. Conclusions The Y2TEC intervention is well positioned to help decrease HIV-related disparities in youth living with HIV through its innovative use of video-counselling technologies and an integrated focus on HIV, mental health and substance use.

by Agajie Likie Bogale, Tilahun Teklehaymanot, Jemal Haidar Ali, Getnet Mitike Kassie Background To establish successful strategies and increasing the utilization of preventive services, there is a need to explore the extent to which the general female population is aware and use the service for cervical cancer-screening among women infected with HIV in Africa. Available evidences in this regard are controversial and non-conclusive on this potential issue and therefore, we estimated the pooled effect of the proportion of knowledge, attitude and practice of HIV infected African women towards cervical cancer screening to generate evidence for improved prevention strategies. Methods We applied a systematic review and meta-analysis of studies conducted in Africa and reported the proportion of knowledge, attitude and practice towards cervical cancer screening. We searched electronic databases: PubMed/Medline, SCOPUS, ScienceDirect, Web of science, Cumulative Index of Nursing and allied Health Sciences (CINAHL) and Google scholar databases to retrieve papers published in English language till August 2020. We used random-effects model to estimate the pooled effect, and funnel plot to assess publication bias. The registration number of this review study protocol is CRD42020210879. Results In this review, we included eight published papers comprising 2,186 participants. The estimated pooled proportion of knowledge of the participants was 43.0% (95%CI:23.0–64.0) while the pooled estimates of attitudes and practices were 38.0% (95%CI: 1.0–77.0) and 41.0% (95%CI: 4.0–77.0), respectively. The proportion of the outcome variables were extremely heterogeneous across the studies with I2> 98%). Conclusion The pooled estimates of knowledge, attitude and practice were lower than other middle income countries calls for further activities to enhance the uptake of the services and establish successful strategies.

Tennant, Pedro L. Alonso, Inácio Mandomando Background Rotavirus vaccines have been adopted in African countries since 2009, including Mozambique (2015). Disease burden data are needed to evaluate the impact of rotavirus vaccine. We report the burden of rotavirus-associated diarrhea in Mozambique from the Global Enteric Multicenter Study (GEMS) before vaccine introduction. Methods A case-control study (GEMS), was conducted in Manhiça district, recruiting children aged 0–59 months with moderate-to-severe diarrhea (MSD) and less-severe-diarrhea (LSD) between December 2007 and November 2012; including 1–3 matched (age, sex and neighborhood) healthy community controls. Clinical and epidemiological data and stool samples (for laboratory investigation) were collected. Association of rotavirus with MSD or LSD was determined by conditional logistic regression and adjusted attributable fractions (AF) calculated, and risk factors for rotavirus diarrhea assessed. Results Overall 915 cases and 1,977 controls for MSD, and 431 cases and 430 controls for LSD were enrolled. Rotavirus positivity was 44% (217/495) for cases and 15% (160/1046) of controls, with AF = 34.9% (95% CI: 32.85–37.06) and adjusted Odds Ratio (aOR) of 6.4 p< 0.0001 in infants with MSD compared to 30% (46/155) in cases and 14% (22/154) in controls yielding AF = 18.7%, (95% CI: 12.02–25.39) and aOR = 2.8, p = 0.0011 in infants with LSD. The proportion of children with rotavirus was 32% (21/66) among HIV-positive children and 23% (128/566) among HIV-negative ones for MSD. Presence of animals in the compound (OR = 1.9; p = 0.0151) and giving stored water to the child (OR = 2.0, p = 0.0483) were risk factors for MSD; while animals in the compound (OR = 2.37, p = 0.007); not having routine access to water on a daily basis (OR = 1.53, p = 0.015) and washing hands before cooking (OR = 1.76, p = 0.0197) were risk factors for LSD. Conclusion The implementation of vaccination against rotavirus may likely result in a significant reduction of rotavirus-associated diarrhea, suggesting the need for monitoring of vaccine impact.

Data were downloaded from the AIDS Prevention and Control Information System on May 1, 2019. HIV screening, prevalence, and incidence data were analyzed from 2008 to 2018. The incidence of HIV was calculated from the results of BED testing. SPSS software (ver. 19.0) was used for the analysis. The number of people screened for HIV increased by 229.7% from 2008 to 2018, while the incidence of HIV increased from 1.14‱ (2010) to 1.67‱ (2018), peak by 2015 (2.28‱). The proportion of people screened for HIV in medical institutions increased from 62.0% in 2008 to 67.1% in 2018, while of all positive tests, 47.9% were conducted at medical institutions in 2008, which increased to 63.2% in 2018. VCT and STD clinic attendees, who had only 4.5% of all those undergoing HIV tests, accounted for 23.7% of all HIV positive in 2018. The rate of HIV-positive people and incidence of HIV both increased in Zhejiang Province between 2008 and 2015. The most effective strategy for detecting HIV new cases is screening visitors to VCT and STD clinics.

AbstractBackground We investigated whether higher-intensity exercise provided greater decrease in markers of inflammation, and whether responses differed by HIV serostatus.MethodsPeople with HIV (PWH; n = 32) and controls (n = 37) aged 50–75 years completed 12 weeks moderate-intensity exercise, then were randomized to moderate- or high-intensity exercise for 12 additional weeks (n = 27 and 29, respectively). Inflammation biomarkers were measured at 0, 12, 24 weeks. Mixed and multiple regression models were adjusted for baseline inflammation, age, and body mass index.ResultsBaseline tumor necrosis factor-α (TNF-α), soluble TNF receptor 2 (sTNFR2), and soluble CD14 (sCD14) were significantly higher among PWH than controls (P < .04). From week 0–12, changes in interleukin-6 (IL-6), TNF-α, and sTNFR1 were not significantly different by HIV serostatus. We found no significant interaction between HIV serostatus/exercise intensity on week 12–24 changes in IL-6, TNF-α, and sTNFR1. Among high-intensity exercisers, PWH and controls had significant increases in sCD14 (P ≤ .003), controls significant increases in IL-10 (P = .01), and PWH nonsignificant decrease in highly sensitive C-reactive protein (P = .07). Other markers were not significantly different by serostatus or intensity.ConclusionsModerate and high-intensity exercise elicited similar effects on inflammation among PWH and controls, with additional beneficial effects seen among high-intensity exercisers. Increase in sCD14 and attenuated IL-10 increase (PWH only) merit further study.Clinical Trials RegistrationNCT02404792.

AbstractBackgroundImmune reconstitution inflammatory syndrome (IRIS) is a common cause of morbidity among people with human immunodeficiency virus (PWH) who initiate antiretroviral therapy (ART) with severe lymphopenia. Easily accessible tools that reliably predict emergence and elucidate pathogenesis of IRIS are needed to facilitate improved clinical management.MethodsPlasma levels of biomarkers were measured before ART initiation in a large multinational cohort of ART-naive PWH with severe immunosuppression (CD4+ count <100 cells/mm3) in United States, Kenya, and Thailand. We performed a series of multiparametric analyses of inflammatory and clinical biomarkers and developed a composite score merging relevant biomarkers for use in a prediction model.ResultsWe identified a distinct baseline inflammatory profile and changes in inflammatory networks among biomarkers in participants who subsequently developed mycobacterial or viral IRIS. We also developed a composite score incorporating biomarkers associated with IRIS (interleukin-6 [IL-6], IL-10, IL-27, sCD14, interferon-γ, tumor necrosis factor-α, hyaluronic acid, D-dimer, body mass index, and hemoglobin) that accurately predicted mycobacterial IRIS and death in this cohort.ConclusionsSystemic inflammatory profiles in PWH with severe immunosuppression are predictive of IRIS. Composite scores for the prediction of mycobacterial IRIS and death could be useful for risk stratification in PWH and lymphopenia initiating ART.Clinical Trials Registration NCT00286767.
