Over the past few years, neuroimaging studies have been performed in young adults with perinatally acquired HIV (PHIV) to study the impact of HIV infection on the central nervous system (CNS), but no recent review have been published. This review aims to identify brain areas where PHIV eems to have greater impact taking into account demographic, behavioral, and clinical characteristics in PHIV infected patients. For this purpose, PubMed and Medline searches were carried out which included studies from 2010 to April 2020. We performed a systematic review and included 26 articles using structural (brain morphometry and diffusion tensor imaging) and functional magnetic resonance imaging methods involving 1182 PHIV-infected participants. Ample evidence has been provided of HIV effects on underlying brain structure. However, information recorded in the studies is commonly incomplete and results sometimes contradictory. In addition to future improvements and dissemination of tools for the developing brain MRI processing and analysis, the inclusion of data related to HIV infection itself (including clinical and immunovirological characteristics as well as detailed information about antiretroviral treatment such as age at ART initiation) may be of vital importance to the better understanding of the impact of the disease on CNS.

Background: Long-term non-progressors (LTNPs) are small subsets of HIV-infected subjects that can control HIV-1 replication for several years without receiving ART. The exact mechanism of HIV-1 suppression has not yet been completely elucidated. Although the modulatory role of microRNAs (miRNAs) in HIV-1 replication has been reported, their importance in LTNPs is unclear. Objective: The aim of this cross-sectional study was to assess the expression pattern of miR-27b, -29, -150, and -221, as well as their relationship with CD4+ T-cell count, HIV-1 viral load, and nef gene expression in peripheral blood mononuclear cells (PBMCs) of untreated viremic patients and in LTNPs. Methods: MiRNAs expression levels were evaluated with real-time PCR assay using RNA isolated from PBMCs of LTNPs, HIV-1 infected naive patients, and healthy people. Moreover, CD4 T-cell count, HIV viral load, and nef gene expression were assessed. Results: The expression level of all miRNAs significantly decreased in the HIV-1 patient group compared to the control group, while the expression pattern of miRNAs in the LNTPs group was similar to that in the healthy subject group. In addition, there were significant correlations between some miRNA expression with viral load, CD4+ T-cell count, and nef gene expression. Conclusion: The significant similarity and difference of the miRNA expression pattern between LNTPs and healthy individuals as well as between elite controllers and HIV-infected patients, respectively, showed that these miRNAs could be used as diagnostic biomarkers. Further, positive and negative correlations between miRNAs expression and viral/cellular factors could justify the role of these miRNAs in HIV-1 disease monitoring.

Background Short-cycle therapy (SCT) is the administration of ART for 4 or 5 consecutive days a week, followed by 3 or 2 days off therapy. Its benefits include improving patient satisfaction and reducing ART toxicity and costs. Methods In this observational study we included HIV-infected adults with a three-drug ART containing rilpivirine, a history of long-term virological suppression and no evidence of resistance to previous drug regimens. Patients switched to a SCT of 4 days on/3 days off and were followed for 48 weeks with regular check-ups. The primary outcome was virological suppression; secondary outcomes were changes in CD4+ cells and rilpivirine plasma concentration, the occurrence of adverse events and resistance in the case of failure, and patient satisfaction. Results At week 48 no virological failure was observed, with a virological suppression rate of 30/30 (100%). Three patients switched back to continuous therapy for other reasons, with an overall success rate of SCT of 30/33 (90.9%, 95% CI = 81.24% to 100%). The CD4+ mean value increased by +64 cells/mm3 (95% CI = −59 to +187 cells/mm3; P = 0.052). No adverse events were observed and the mean total score in the satisfaction questionnaire was 57.7/60 (96.22%). Rilpivirine plasma concentration was below the efficacy threshold in 71.3% of the samples, suggesting that the patients’ characteristics, more than the drug’s pharmacokinetics, played a role in maintaining virological suppression. Conclusions SCT with rilpivirine-containing regimens could be an effective alternative to continuous therapy in selected HIV-infected patients with previous long-term virological suppression.

Influenza is known to cause severe respiratory illness in HIV-infected adults, but there are few data describing the relationship between HIV infection and influenza in West African countries such as Ghana. We conducted a prospective cohort study in the Shai-Osudoku and Ningo Prampram districts of Ghana from 2014 to 2016. Beginning May 2014, 266 HIV-infected and 510 HIV-uninfected participants age 18 to 73 years were enrolled and monitored for 12 months. We observed 4 and 11 laboratory-confirmed influenza cases among HIV-infected and HIV-uninfected persons, respectively. The overall rate of laboratory-confirmed influenza among HIV-infected participants was 15.0 per 1,000 person years (PY) (95% CI, 0.3–29.80 per 1,000 PY), whereas that among HIV-uninfected participants was 21.6 per 1,000 PY (95% CI, 8.8–34.3 per 1,000 PY) (incidence density ratio, 0.70; P = 0.56). Our study found no significant difference in the incidence of laboratory-confirmed influenza-associated illness among HIV-infected and HIV-uninfected individuals in Ghana.

Background Previously selected lamivudine resistance-associated mutations (RAMs) may remain archived within the proviral HIV-DNA. Objectives To evaluate the ability of proviral DNA genotyping to detect lamivudine RAMs in HIV-1 virologically suppressed participants; the correlation between Sanger and next generation sequencing (NGS); and predictive factors for detection of lamivudine RAMs in proviral DNA. Methods Cross-sectional study of participants on stable antiretroviral therapy and suppressed for ≥1 year. Analysis of proviral DNA was performed by Sanger sequencing in whole blood and by NGS in PBMCs. Results We analysed samples from 102 subjects (52 with and 50 without lamivudine RAMs in historical plasma RNA-genotypes). Among participants with previous lamivudine resistance, Sanger sequencing detected RAMs in 26.9%. Detection rates significantly increased using NGS: 47.9%, 64.6%, 75% and 87.5% with the 20%, 10%, 5% and 1% thresholds, respectively. As for participants without historical lamivudine resistance, Sanger detected the RAMs in 1/49 (2%), and NGS (5% threshold) in 8/45 (17.8%). Multivariate models fitted to the whole population revealed that having a history of lamivudine resistance was a risk factor for detection of lamivudine RAMs by NGS. Among participants with historical lamivudine resistance, multivariate analysis showed that a longer time since HIV diagnosis was associated with persistence of archived mutations by NGS at thresholds of >10% [OR 1.10 (95% CI: 1.00–1.24)] and >5% [OR 1.16 (95% CI: 1.02–1.32)]. Conclusions Proviral DNA Sanger sequencing does not detect the majority of historical lamivudine RAMs. NGS increases the sensitivity of detection at lower thresholds, although the relevance of these minority populations with lamivudine RAMs needs further evaluation.

Introduction: Key populations have disproportionately higher HIV prevalence rates than the general population.Objective: To determine the level of virologic suppression and associated factors in female Commercial Sex Workers (CSW) who completed six months of ART and compare with the female general population (GP).Methods: Clinical records of CSW and GPs who initiated ART between December 2014 to December 2016 from seven urban clinics were analyzed to determine virologic suppression (viral load < 1000 copies/ml) and associated factors.Results: We identified 218 CSW and 182 female GPs. CSW had median age of 28 (IQR 25-31) vs 31 (IQR 26-37); median baseline CD4 446 (IQR 308-696) vs 352 (IQR 164-493) cells/microL; and optimal ART adherence levels at 70.6% vs 92.8% respectively, compared to GP. Virologic suppression in CSW and GPs was 85.7% and 89.6% respectively, P=0.28. Overall virologic suppression in CSW was 55% while Retention in care after 6 months of ART was 77.5%. Immediate ART initiation (

Background: Malaria parasite has been observed to be a common infection in Human Immunodeficiency virus (HIV), an increase malaria infection in adults. Objective: This experimental study is sets to determine the prevalence and density of malaria parasitaemia in Warri com- munity, South-Southern Nigeria. Methods and Results: A total of 600 participants were screened for Human immunodeficiency virus and malaria parasite using WHO systems two and Geimsa staining technique for thick and thin blood films and absolute parasite counts done respectively. The prevalence rate of 38% and 39% were obtained for malaria parasite infection among HIVSP and HIV/ span>SN respectively. The difference in malaria parasite infection was not statistically significant (P>0.05) between HIVSP and HIVSN. However, the mean parasite density in HIVSP was significant (P

Background CD4+ T cell counts in certain human immunodeficiency virus (HIV)-infected patients called immunological non-responders (INRs) could not return to a normal level even with sustained antiretroviral therapy (ART) because of persistent immune activation, which is associated with pro-inflammatory cytokines production and an altered intestinal microbiome profile. Changes in gut bacterial composition have been linked to low CD4+ T cell counts in HIV-infected individuals. However, the association between CD4+ T cell counts and gut microbiota community composition and cytokines levels in INRs (CD4+ T cell counts Methods To address this issue, we carried out a cross-sectional study of 34 HIV-infected INRs. The patients were divided into CD4 count > 200 cells/μL group and CD4 count 16S rRNA gene sequencing. We also compared CD8+ T cell counts, pro-inflammatory cytokines levels, and nutritional status between the two groups. Results Compared to INRs with CD4 count > 200 cells/μL, those with CD4 count Ruminococcaceae was less abundant in the CD4 count 200 cells/μL group, and difference in alpha diversity was observed between the two groups. Moreover, CD4+ T cell counts were negatively associated with TNF-α and IL-1α levels and positively associated with the relative abundance of Ruminococcaceae. Conclusions Our study demonstrated that lower CD4+ T cell counts in INRs are associated with a reduced abundance of Ruminococcaceae in the gut and elevated serum pro-inflammatory cytokines levels. Thus, interventions targeting gut microbiota to increase CD4+ T cell counts are a potential strategy for promoting immune reconstitution in HIV-infected INRs.

Background: Dolutegravir (DTG) plus lamivudine (2-DR) is suggested as an initial and switch option in HIV-1 treatment. Objective: To analyze the effectiveness, durability, and safety of 2-DR compared with DTG plus abacavir/lamivudine (3-DR). Methods: This was an observational, ambispective study that included all treatment-naïve (TN) and treatment-experienced (TE) patients who started 2-DR or 3-DR between July 1, 2018, and November 30, 2020. The primary end point was noninferiority, at 24 and 48 weeks, of 2-DR versus 3-DR regarding the percentage of patients with viral load (VL)≥50 and 200 copies/mL in TN (4% margin) and VLResults: 242 patients were included (53 TN and 189 TE). Two TN patients on 2-DR had VL≥50 copies/mL and 1 had VL≥200 copies/mL at week 24. In TE patients on 2-DR, 90.2% achieved VLConclusion and Relevance: Our results did not show noninferiority in terms of virological effectiveness. Nevertheless, all effectiveness measures support the use of 2-DR in a real-life cohort of TN and TE. Additionally, durability and safety of 2-DR were confirmed to be similar to that of 3-DR.

Background Human immunodeficiency virus (HIV) infection induces epigenetic age acceleration (EAA), but it remains unclear whether epigenetic aging continues to accelerate during successful antiretroviral therapy (ART) and prolonged virological suppression. Methods We longitudinally analyzed 63 long-term aviremic HIV-infected adults. Using blood DNA methylation patterns, we calculated EAA measures based on 3 epigenetic clocks (Horvath’s clock, PhenoAge, and GrimAge). We recorded the emergence of serious AIDS-related and non-AIDS-related events throughout the study to assess its association with EAA. Results All participants were on stable ART and were virologically suppressed. After 4 years of follow-up, PhenoAge-EAA and GrimAge-EAA showed no differences, whereas Horvath-EAA slightly decreased (median difference, –0.53 years; P = .015). Longitudinal changes in EAA measures were independent of changes in CD4 cell counts, the ART regimen, or other HIV-related factors. Nineteen percent of participants experienced a serious clinical event during the study. Horvath-EAA was significantly higher at baseline in participants with clinical events (P = .027). After adjusting for confounders, we found a trend toward an association of higher levels of all EAA measures at baseline with serious clinical events. Conclusions Epigenetic aging did not accelerate in long-term aviremic HIV-infected adults after 4 years of successful ART. EAA measures deserve further study as potential tools for predicting clinical events.

espanolObjetivos. Argentina ha informado de altos niveles de farmacorresistencia transmitida (TDR), en mujeres embarazadas infectadas por el VIH por secuenciacion poblacional. Nuestro objetivo fue describir, en pacientes con TDR, el porcentaje de cuasiespecies que albergan mutaciones de resistencia (RAM) y la carga mutacional (ML). Pacientes y metodos. Estudio retrospectivo en una cohorte de 40 mujeres embarazadas VIH positivas naive, cuyas muestras pretratamiento habian sido genotipificadas por TRUGENE (periodo 2008-2014). Las muestras se genotipificaron por secuenciacion ultraprofunda y se calculo la ML considerando la carga viral multiplicada por la frecuencia de las cuasiespecies que albergan RAMs. Resultados. La TDR para ITINN, ITIAN e IP fue del 17,5% (n=7 pacientes), 10% (n=4), 12,5% (n=5) respectivamente. Las RAMs ITINN predominantes fueron K103N (n=4; 10%) y G190A/E/ S (n=3; 7,5%). Para los ITINN, el 78% de los RAM estaban presentes en >93,5% de la poblacion viral y la ML fue >1000 copias/ml (c/mL) para el 89%, con una mediana (IQR) de 8330 c/ml (7738-29796). Se describieron los siguientes RAM de ITIAN (% de cuasiespecies, ML): T215I (99,7%, 11014 c/ml); D67G (1,28%, 502 c/ml); M41L (79,8%, 88578 c/mL) y M184I (1,02%, 173 c/mL). Las IP-RAMs mas frecuentes fueron I85V, M46I, I50V y L90M (n=2, 5% cada una). Para los IP, las cuasiespecies con RAMs fueron Conclusion. Los ITINN-RAMs son predominantes dentro de la poblacion viral, por lo general superan el umbral de 1000 c/mL, que indicaria un riesgo potencial mas alto de transmision perinatal. Por el contrario, las mutaciones de IP aparecen principalmente como variantes minoritarias, con un riesgo menor de transmision. Para ITIAN, las cuasiespecies que albergan RAM y los valores de ML fueron variables. EnglishObjective. Argentina has reported high levels of transmitted drug resistance (TDR), in HIV-infected pregnant women by population sequencing. We aimed to describe, in patients with TDR, the percentage of quasispecies harboring resistance mutations (RAMs) and mutational load (ML). Patients and Methods. Retrospective study in a cohort of 40 naive HIV-infected pregnant women, whose pretreatment samples had been genotyped by TRUGENE (period 2008-2014). Samples were re-sequenced with Ultra-deep Sequencing and ML was calculated considering baseline HIV-1 RNA load multiplied by the frequency of quasispecies harboring RAMs. Results. TDR for NNRTIs, NRTIs and PIs was 17.5% (n=7 patients), 10% (n=4), 12.5% (n=5) respectively. Predominant NNRTI RAMs were K103N (n=4; 10%) and G190A/E/S (n=3; 7.5%). For NNRTIs, 78% of RAMs were present in >93.5% of viral population and ML was >1000 copies/mL (c/mL) for 89%, with a median (IQR) of 8330 c/ml (7738-29796). The following NRTI RAMs were described (per patient: % of quasispecies, ML): T215I (99.7%, 11014 c/ml); D67G (1.28%, 502 c/mL); M41L (79.8%, 88578 c/mL) and M184I (1.02%, 173 c/mL). Most frequent PI-RAMs were I85V, M46I, I50V and L90M (n=2, 5% each). For PIs, quasispecies with RAMs were Conclusion. NNRTI-RAMs are predominant within the viral population, usually exceeding the threshold of 1000 c/mL, indicating potential higher risk of perinatal transmission. Conversely, PI mutations appear mostly as minority variants, with potential lower risk of transmission. Among NRTI, quasispecies harboring RAMs and ML values were variable.

Background There are limited data exploring antiretroviral therapy (ART) changes and time to change among South Africa young people living with HIV/AIDS. Objective We describe the time to first drug switch, which includes ART regimen change (three drug switch) and substitutions (single drug switch). We describe common reasons for ART switch among young people aged 10 to 24 years in South Africa. Methods We conducted a retrospective cohort study at a primary health care clinic in Cape Town, South Africa, providing ART to HIV-infected adolescents and adults since 2002. Those aged 10 to 24 years at ART initiation, who accessed care clinic between September 2002 and April 2019. Data was retrieved from electronic information systems: ART regimens, ART changes, dates for initiation or stop of each drug/regimen, laboratory results (viral loads, haemoglobin, liver enzyme results, and creatinine to support the reason for ART switch. From written records, we abstracted reason for single drug switch or regimen change, as well as socio demographic and clinical data. We fitted cox regression models to determine factors associated with ART switch (Having a change in one or more drugs in ART combination) and the rate of occurrence. Results Of 2601 adolescents included, 605 (24.9%) adolescents switched ART over 5090.5 person years at risk (PYAR), a rate of 11.9 /100PYAR. Median follow-up time was 4.4 (± 3.2) years. At multivariable analysis, the older age group was protective of the risk of ART switch: adjusted Hazard Ratio [aHR] 0.78, 95% CI 0.62–0.98, transfer status [transferred out 1.42 [1.11–1.82]. The hazard of ART switch increased with more severe HIV-disease at ART start, as observed by increasing WHO clinical stage or reduced CD4 count at baseline. The primary reasons for ART switch were side effects (20.0%), virological failure (17.9%) and formulation switch (27.8%). Others reasons included pregnancy, Hepatitis B, tuberculosis and psychosis. Conclusion ART switches are frequent and occur at a consistent rate across 7.5 years from initiation. The main reasons for ART switch were virological failure and drug side effects.

Background Primary analysis at 24 weeks showed that switching to rilpivirine plus darunavir/cobicistat was non-inferior to continuing a standard three-drug antiretroviral regimen in virologically suppressed people with HIV. We present efficacy and safety data from the 48-week analysis. Methods PROBE 2 is a randomized, open-label trial. Adults who were on a three-drug therapy and had had Findings 160 participants were recruited and randomized. At week 48, 70 (87.5%) in the early switch group and 76 (94.8%) in the late switch group maintained HIV-RNA Interpretation The combination of rilpivirine plus darunavir/cobicistat sustained virological suppression, was associated with a low frequency of virological failure, and had a favorable safety profile, which support its use as a nucleoside reverse transcriptase inhibitor-sparing and integrase inhibitor-sparing alternative to three-drug regimens.

Objective To molecularly characterise the relationship between Epstein-Barr virus (EBV) genotypes and Pashtun ethnicity. Methods The cross-sectional study was conducted from November 2018 to December 2019 after approval from the Gomal University, Dera Ismail Khan, Pakistan, and comprised blood samples from transgender sex workers who were seropositive for human immunodeficiency virus-1 and seronegative for human immunodeficiency virus residing in two cities of Khyber Pakhtunkhwa province and Islamabad, the federal capital. Formalin-fixed paraffin-embedded (FFPE). Samples were collected from the partner institute along with the patients data, but without any follow-up from the study subjects which was purely on the basis of physical availability. β-globin gene and EBER-1(EBV encoded small RNA-1) were amplified for qualitative assessment and existence of Epstein-Barr virus. Characterisation of EBNA-2 (EBV Nuclear Antigen-2 was done through nested polymerase chain reaction. Results Of the 80 subjects, 40(50%) each were seropositive and seronegative individuals. The overall mean age was 28±6.917 years. Among the seropositive group, 38(95%) were homosexual and 2(5%) were heterosexual. Among the seropositive group, 16(40%) had Epstein-Barr virus genotype 1 and 6(15%) had genotype 2, while co-infections were found in 2(5%) subjects. In the seronegative group, 36(90%) subjects had Epstein-Barr virus genotype 1, while there was no case of genotype 2 or co-infection. EBV-2 genotypes with HIV seropositivity showed strong association (p=0.005). Amplification for the EBER-1 gene was done in all the 80(100%) samples. Conclusions Epstein-Barr virus EBV genotype 1 was found to be the most frequent type, while genotype 2 and co-infections were detected in only seropositive samples.

Intimate partner violence (IPV) has been highlighted as one of the challenges to the effectiveness of the Prevention of Mother-to-Child Transmission of HIV (PMTCT) programs in rural areas in South Africa. This study aimed at assessing the prevalence of prenatal and postnatal physical as well as psychological IPV, and corresponding time-invariant and time-varying predictors, among HIV-positive women attending PMTCT services in rural South Africa. The Conflict Tactics Scale (CTS) was used to assess IPV at four time points prenatal and postnatal. This study highlighted high levels of physical and psychological IPV experienced by HIV-infected women during pregnancy and in the first year after childbirth. Time-invariant predictors and time-varying predictors of physical IPV and psychological IPV were individual, social, and behavioral factors. Multi-dimensional evidence-based interventions are needed to deal with the high levels of prenatal and postnatal physical as well as psychological IPV experienced by these women.

Young people perinatally infected with HIV (pHIV) are at risk of a lowered health-related quality of life (HRQOL). Previous evaluation of the NeurOlogical, VIsual and Cognitive performance in HIV-infected Children (NOVICE)-cohort showed no difference in HRQOL between pHIV and matched HIV-uninfected controls (HIV-), yet a higher percentage of pHIV had impaired HRQOL. The aim of this study is to compare the change over time in HRQOL of pHIV to HIV- over a 5-year period. We used the Pediatric Quality of Life Inventory (PedsQL)™ 4.0 to repeat HRQOL assessment. High PedsQL scores indicate good HRQOL. Fifteen/33 (45.5%) pHIV and 17/37 (45.9%) HIV- completed both assessments. At the first assessment, the mean age was 13.1 years (range 8.0–18.4). PHIV scored higher than HIV- on Emotional functioning and on Total scale score. After five years, the mean age was 17.6 years (range 12.1–22.8). PHIV scored higher than HIV- on all scales, except Social functioning. PHIV did not differ significantly from the Dutch norm on either time-point. LMEM showed no difference in change over time for any of the PedsQL scales. In this study, young people with pHIV receiving high-quality health care, including monitoring of HRQOL, remain to experience a good HRQOL.

Chronic disease of people living with human immunodeficiency virus (HIV) infection are now approaching those of the general population. Previous, in vitro studies shown that HIV causes arterial injuries resulting in inflammation and atherosclerosis but direct relationship between HIV infection clinical stages and lower extremity arterial disease (LEAD) remain controversial. No study assessed, with an accurate method, both the prevalence of LEAD and the influence of HIV severity on LEAD in HIV outpatients in Central Africa. A cross-sectional study was conducted among 300 HIV-infected outpatients, aged ≥ 40 years in Bujumbura, Burundi. All patients underwent ankle-brachial index (ABI) measurement and LEAD was diagnosed by ABI ≤ 0.9. The prevalence of LEAD was 17.3% (CI 95% 13.2–22.1). The mean age was 49.6 ± 7.1 years. On multivariable analysis, factors associated with LEAD were hypertension (OR = 2.42; 95% CI 1.10–5.80), and stage IV HIV clinical infection (OR = 4.92, 95% CI 1.19–20.36). This is the first study performed on a large HIV population in Central Africa, reporting high LEAD prevalence. It underlines the influence of HIV infection on peripheral atherosclerosis at latest clinical stages and the need for LEAD screening in HIV-infected patients.

Background: Sexually transmitted infections (STIs) can be transmitted from mother to neonate. We determined the frequency of mother-to-child transmission (MTCT) of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis to the newborn nasopharynx. Methods: This study was nested in a cohort study of etiologic testing versus syndromic management for STIs among pregnant women living with human immunodeficiency virus in South Africa. Mothers were tested for STIs using the GeneXpert platform within 60 days after delivery. Nasopharyngeal swabs were obtained from newborns of mothers with a positive STI test; these were then tested by Xpert® on the same day based on the maternal STI diagnosis. Results. We tested nasopharyngeal swabs from 85 STI-exposed newborns; 74 (87%) were tested within 2 weeks after birth (median five; range 2–12 days). MTCT frequency of any STI was 30/74 (41%); 43% (23/53) for C. trachomatis, 29% (2/7) for N. gonorrhoeae, and 24% (6/25) for T. vaginalis. Also, 4/11 (36%) swabs obtained between 14 and 60 days after delivery tested positive for STI. Conclusions: There was a high frequency of MTCT of STIs to the nasopharynx of newborns in our setting. The impact of nasopharyngeal colonization and the benefits of STI testing on newborn health remain to be determined.

Human immunodeficiency virus (HIV) is associated with lower nitric oxide (NO) bioavailability and vascular dysfunction. Nitrate-rich beetroot juice (BJ) has been shown to acutely increase NO availability and vascular function in healthy and individuals at high risk for cardiovascular disease. Thus, we tested the effects of BJ ingestion on flow-mediated dilation (FMD) and pulse wave velocity (PWV) measurements in healthy and HIV-infected patients. Thirteen HIV-infected individuals (age, 36 ± 10 years) and 18 healthy (age, 27 ± 8 years) participated in the study. Individuals were submitted to vascular tests such as FMD and pulse PWV at pre (T0) and at 120 min (T120) after BJ and placebo (PLA) ingestion. The %FMD at T0 of the control group was significantly higher than the %FMD at T0 of the HIV individuals in both interventions. BJ improved the %FMD at T120 when compared with T0 in the HIV and control groups. There was no change in %FMD after PLA ingestion in the control and HIV groups. There were no differences between groups (control vs HIV), time points (T0 vs T120), and interventions (BJ vs PLA) for PWV. Our findings showed that nitrate-rich BJ ingestion acutely improved vascular function in healthy and HIV-infected patients. Clinical Trials Registry no. NCT03485248. Novelty: HIV is associated with lower NO bioavailability and vascular dysfunction. Acute supplementation with nitrate-rich BJ has been shown to acutely increases NO bioavailability. We showed for the first time that BJ acutely improves endothelial function in HIV-infected patients.

Objective methods of measuring antiretroviral adherence are limited. We assessed the relationship between tenofovir disoproxil fumarate (TDF) hair concentrations, self-reported adherence, and virological outcomes in HIV-infected adolescents in Harare, Zimbabwe. HIV-infected adolescents on atazanavir/ritonavir-based second-line treatment for >6 months with viral load (VL) ≥1,000 copies/mL were randomized to either modified directly administered antiretroviral therapy (mDAART) or standard of care. Hair and VL samples were collected at baseline and after 90 days. Treatment outcome was defined as TDF concentrations in hair. Virological suppression was defined as VL

The purpose of this study was to assess the prevalence of chlamydia or gonorrhea and factors associated with the diagnoses among people with HIV (PHIV) in the Ryan White Program Part A (RWP) in Miami-Dade County, Florida. We used 2017 calendar year data to identify factors associated with a chlamydia or gonorrhea diagnoses using logistic regression. About 50% of the 7110 PHIV who were ≥18 years old in active Ryan White care in 2017 reported being screened for chlamydia or gonorrhea. Of those screened, 2.3% reported diagnoses of chlamydia, gonorrhea or both. In the adjusted model, compared to PHIV ≥40 years-old, PHIV aged 18-24 and 25-39 years reported higher odds of diagnoses (adjusted odds ratio [aOR] 4.29; 95% confidence interval [CI]: 1.73-10.63 and aOR 4.58; 95% CI; 2.62-7.99 respectively). Those with multiple sexual partners in the last 12 months reported higher odds of diagnoses (aOR 1.67; (95% CI; 1.04-2.69)). Screening rates for chlamydia or gonorrhea are low, relative to CDC guidelines. Interventions are needed to increase rates of screening and targeted behavioral risk reduction techniques are highly recommended among those 18-39 years of age and those who have multiple sexual partners.

Kidney transplant (KT) outcomes for HIV-infected (HIV+) persons are excellent, yet acute rejection (AR) is common and optimal immunosuppressive regimens remain unclear. Early steroid withdrawal (ESW) is associated with AR in other populations, but its utilization and impact are unknown in HIV+ KT. Using SRTR, we identified 1225 HIV+ KT recipients between January 1, 2000, and December 31, 2017, without AR, graft failure, or mortality during KT admission, and compared those with ESW with those with steroid continuation (SC). We quantified associations between ESW and AR using multivariable logistic regression and interval-censored survival analysis, as well as with graft failure and mortality using Cox regression, adjusting for donor, recipient, and immunologic factors. ESW utilization was 20.4%, with more zero HLA mismatch (8% vs 4%), living donors (26% vs 20%), and lymphodepleting induction (64% vs 46%) compared to the SC group. ESW utilization varied widely across 129 centers, with less use at high- versus moderate-volume centers (6% vs 21%, P < .001). AR was more common with ESW by 1 year (18.4% vs 12.3%; aOR: 1.08 1.612.41 , P = .04) and over the study period (aHR: 1.02 1.391.90 , P = .03), without difference in death-censored graft failure (aHR 0.60 0.911.36 , P = .33) or mortality (aHR: 0.75 1.151.77 , P = .45). To reduce AR after HIV+ KT, tailoring of ESW utilization is reasonable.

How to activate adaptive coping strategies has an important and practical meaning for the quality of life of people living with HIV (PLHIV); however, few studies have focused on the effects of sleep disturbances and HIV-related physical symptoms on coping strategies. The specific relationships among coping strategies, sleep disturbances and HIV-related physical symptoms were unknown. We performed a path analysis to examine the proposed model of relationships among sleep disturbances, physical symptoms, and coping strategies. A convenience sample of 69 HIV-positive Asian Americans in San Francisco, Los Angeles, and New York City were recruited and data were collected on demographics, sleep disturbances, HIV-related physical symptoms, and coping strategies. Sleep disturbances directly affect maladaptive coping (β = 0.34), and physical symptoms directly affect adaptive coping (β = 0.30) and maladaptive coping (β = 0.24). Interventions designed to decrease sleep disturbances and physical symptoms should be developed to enhance adaptive coping and reduce maladaptive coping among Asian Americans with HIV.

We report the interesting experience of the African Village of Hope (Dodoma, Tanzania) where HIV-positive orphan children have been hosted, cured, and educated in the last 15 years. The particular attention to beauty in the education of the children amazed us when we were in the village working as doctors. The project and the effort to create such a model of social and medical assistance were born from the idea of the founders, Sister Maria Rosaria Gargiulo and Don Vincenzo Boselli. In light of this experience and of the healthy result obtained in the village, we believe that education in the perception of beauty is a formative aspect for all children, but may also be a powerful adjuvant therapy in severely immunocompromised young patients.

WHAT IS KNOWN AND OBJECTIVE Therapeutic alternatives to simplify antiretroviral therapy (ART) in HIV-infected children are needed. We report our experience with abacavir(ABC)/lamivudine(3TC) individualized dose compounded capsules (IDCC). COMMENT We present a prospective case series of HIV-infected children who did not weigh enough to receive the adult fixed-dose combination including ABC/3TC 600mg/300mg, and were treated with weight-adapted ABC/3TC IDCC in Barcelona, Spain. Thirteen patients (12 girls) received ABC/3TC IDCC for a median(IQR) time of 30(17-54) months. No significant changes were observed in CD4 cell counts, weight or height z-scores over time. Suppression of viral replication was maintained in 7 patients with undetectable viremia at baseline. Another 5 patients achieved viral suppression with ABC/3TC IDCC-based ART, while one non-adherent girl did not. No adverse events related to ABC/3TC IDCC were observed. WHAT IS NEW AND CONCLUSION Despite small numbers, the long-term use of ABC/3TC IDCC was feasible, safe, and effective in the treatment of HIV-infected children.

BACKGROUND & AIMS: Hepatitis C virus (HCV) reinfection among high risk groups threatens HCV elimination goals. We assessed HCV reinfection rates among men who have sex with men (MSM) in British Columbia (BC), Canada. METHODS: We used data from the BC Hepatitis Testers Cohort, which includes nearly 1.7 million individuals tested for HCV or HIV in BC. MSM who had either achieved sustained virologic response (SVR) after successful HCV treatment, or spontaneous clearance (SC) and had ≥1 subsequent HCV RNA measurement, were followed from the date of SVR or SC until the earliest of reinfection, death, or last HCV RNA measurement. Predictors of reinfection were identified by Cox proportional modelling. The earliest study start date was November 6th , 1997 and latest end date was April 13th , 2018. RESULTS: Of 1,349 HCV-positive MSM who met the inclusion criteria, 493 had SC while 856 achieved SVR. 349 (25.65%) had HIV coinfection. We identified 98 reinfections during 5203 person-years (PYs) yielding a reinfection rate of 1.88/100PYs. The reinfection rate among SC (2.74/100PYs) was more than twice that of those with SVR (1.03/100 PYs). Problematic alcohol use (aHR 1.73, 95% CI 1.003-2.92), injection drug use (aHR 2.60, 95% CI 1.57-4.29) and HIV coinfection (aHR 2.04, 95% CI 1.29-3.23) were associated with increased risk of HCV reinfection. Mental health counselling history (aHR 0.24, 95% CI 0.13-0.46) was associated with reduced HCV reinfection risk. CONCLUSIONS: There is the need to engage MSM in harm reduction and prevention services following treatment to reduce reinfection risk.

Background: A better understanding of the baseline characteristics of elderly people living with HIV/AIDS (PLWHA) is relevant because the world’s HIV population is ageing. Objectives: This study aimed to evaluate the baseline characteristics of PLWHA aged ≥ 50years at recruitment to HIV/ AIDS clinic compared against the viral load (VL) and CD4 count among patients attending Kisii Teaching and Referral Hospital (KTRH), Kenya. Methods: We retrospectively evaluated temporal inclinations of CD4 levels, viral load change and baseline demographic characteristics in the electronic records at the hospital using a mixed error-component model for 1329 PLWHA attending clinic between January 2008 and December 2019. Results: Findings showed a significant difference in the comparison between baseline VL and WHO AIDS staging (p=0.026). Overall VL levels decreased over the period significantly by WHO AIDS staging (p200cell/mm3 (p=0.048) and residence (p=0.001). Conclusion: Age, WHO AIDS staging, gender and residence are relevant parameters associated with viral load decline and CD4 count in elderly PLWHA. A noticeable VL suppression was attained confirming possible attainment of VL suppression among PLWHA under clinical care. Keywords: HIV infected elderly patients; Kisii Teaching and Referral Hospital, Kenya.

Human immunodeficiency virus (HIV)-exposed infants may be at increased risk of vaccine-preventable disease. This study was conducted as a post-licensure commitment in this population to evaluate the primary series, antibody persistence, and booster response to a licensed fully liquid hexavalent vaccine containing diphtheria (D), tetanus (T), acellular pertussis (aP), inactivated poliovirus (IPV), hepatitis B (HB), and Haemophilus influenzae type b antigens (PRP~T). This was a Phase III, open-label, randomized study conducted at a single center in the Republic of South Africa. The DTaP-IPV-HB-PRP~T vaccine was administered to HIV-exposed infected (Group A: N = 14) and HIV-exposed uninfected (Group B: N = 50) infants as a 6, 10, 14 week primary series with a toddler booster at 15–18 months of age. Immunogenicity of each antigen was measured using validated assays and vaccine reactogenicity was recorded using diary cards. The low number of HIV-exposed infected participants, due to widespread pre- and peri-natal retroviral treatment, meant that between-group comparisons should be treated with caution. In each group, primary series and booster immune seroprotection rates were strong, and pre-booster antibody persistence was good, although anti-HBs ≥10 mIU/mL in Group A was 78.6% post-primary series, 58.3% pre-booster, and 75.0% post-booster. There were no safety concerns. In conclusion, primary series and booster vaccination of the DTaP-IPV-HB-PRP~T vaccine were immunogenic and safe in HIV-exposed infected and uninfected infants. These results were comparable to historical data in healthy infants and toddlers.

Background: Cardiovascular abnormalities are not much reported among human immunodeficiency virus (HIV) infected children especially in Africa where there is high HIV disease. In addition, the use of highly active antiretroviral therapy (HAART) in such children may have a protective effect on the cardiovascular system. Methods: Cross-sectional study of randomly selected eighty HIV infected and 80 aged matched non- HIV-infected chil- dren were used. HIV-infected children were on HAART for more than 5years and had steadily received the treatment for 6 months prior to the time of the tests. Heights and weights were measured and body mass index calculated. Cardiac indi- ces evaluated were heart rate (HR), PR interval, QRS duration, QT/QTC Interval, P/QRS/T Axis, RV5/SV1 voltage and RV5+SV1 voltage. Results: The average heart rate was significantly higher among HIV infected children on HAART than their non-infected counterparts (P= 0.019). At 0.05 significance level, their PR interval was significantly higher than those in the control group (P=0.050). The average QRS duration result also showed a significant difference between that of test and control subjects (P = 0.022) Conclusion: The HAART usage possibly improved the cardiovascular functioning in the infected children but the protective effects diminish with increase age and longer exposure. Keywords: HIV; cardiovascular; children; HAART.

An HIV-positive man from Zimbabwe living in South Africa sought treatment for multiple clinical signs, including fever, weight loss, anemia, and splenomegaly. We identified in his blood an African rodent piroplasm, Anthemosoma garnhami, related to Babesia species. This finding extends the known geographic and host range of A. garnhami.

Background Neurodevelopmental stimulation programmes can improve developmental outcomes. Antiretroviral therapy (ART) started soon after birth potentially limits the invasion of HIV into the central nervous system. A combination of developmental stimulation and early ART initiation may reduce developmental delays in children with perinatally-acquired HIV infection. Methods At a single site in Johannesburg, South Africa, we enrolled 36 HIV-infected neonates on ART into an intervention group (IG) participating in a yearlong home-based, neurodevelopmental stimulation program. Bayley Scales of Infant and Toddler Development-3rd Edition (BSID-III) assessments were conducted at 12 months. Scores were compared with 24 early-treated HIV-infected infants in an observational group (OG). BSID-III assessments were also conducted for older children in an observational group at 24 or 36 months. Cognitive, language and motor scaled and composite scores were analysed. Results BSID-III scaled and composite scores were all higher in the IG apart from the gross motor scaled score (9.25 vs. 10, p=0.1954). Receptive communication scaled score was significantly higher in the IG (10.96 vs. 9, p=0.0331). IG composite scores were all higher than OG scores. OG children assessed at 24 or 36 months had lower composite scores in all subscales than 12 month OG scores. Conclusions Early-treated HIV-infected children participating in a neurodevelopmental stimulation programme achieved higher BSID-III scores at 12 months compared with early treated HIV-infected children who did not receive the programme.

Human immunodeficiency virus (HIV) infection may be a predictor of undertreatment of patients with lymphoma. We hypothesized treatment with systemic therapy (SysT) or hematopoietic stem cell transplantation (HCT) in the first-line setting leads to improved outcomes and sought to compare the predictors for treatment and outcomes with non-HIV (HIV-) patients.Patients with lymphoma diagnosed between 2004 and 2015 were extracted from the National Cancer Database (NCDB). Patients were categorized as HIV+ and HIV-. First-line treatment was categorized as no systemic therapy reported (noSyst), SysT, or HCT. Multivariate analysis to predict treatment and survival was performed.We identified 552,513 lymphoma patients, of whom 11,160 HIV+ versus 349,607 HIV- patients were eligible for analysis. Among HIV+, the positive predictors for SysT were insurance and higher income, whereas female sex and minority racial status predicted lower likelihood for SysT. Forty HIV+ patients underwent HCT. Treatment of HIV+ lymphoma patients resulted in improved outcomes: 3-year overall survival 43.6% in noSyst versus 58.1% SysT (hazard ratio [HR] 0.56; 95% confidence interval [CI], 0.52-0.61; P .005) versus 62.2% HCT (HR 0.42; 95% CI, 0.14-1.3; P = .08). The outcomes were lower compared to non-HIV patients (3-yr overall survival 67.3% with SysT and 62.2% HCT).Patients with lymphoma with HIV benefit from SysT when feasible but outcomes are worse than non-HIV patients. HCT should be offered to HIV+ patients with lymphoma in the appropriate clinic setting. Individual characteristics of the patients and complications could not be evaluated in the present study but should be a focus for future research.

Background Lesotho adopted the test-and-treat approach for HIV treatment in June 2016, which increased antiretroviral treatment (ART) clinic volume. We evaluated community-based vs. facility-based differentiated models of multimonth dispensing of ART among stable HIV-infected adults in Lesotho. Methods Thirty facilities were randomized to 3 arms, facility 3-monthly ART (3MF) (control), community ART groups (3MC), and 6-monthly community distribution points (6MCD). We estimated risk differences (RDs) between arms using population-averaged generalized estimating equations, controlling for baseline imbalances and specifying for clustering. The primary outcome was retention in ART care by intention-to-treat and virologic suppression as a secondary outcome (ClinicalTrials.gov: NCT03438370). Results A total of 5,336 participants were enrolled, with 1898, 1558, and 1880 in 3MF, 3MC, and 6MCD, respectively. Retention in ART care was not different across arms and achieved the prespecified noninferiority limit (-3.25%) between 3MC vs. 3MF (control); 6MCD vs. 3MF; and 6MCD vs. 3MC, adjusted RD = -0.1% [95% confidence interval (CI): -1.6% to 1.5%], adjusted RD = -1.3% (95% CI: -3.0% to 0.5%), and adjusted RD = -1.2% (95% CI: -2.9% to 0.5%), respectively. After 12 months, 98.6% (n = 1503), 98.1% (n = 1126), and 98.3% (n = 1285) were virally load (VL) suppressed in 3MF, 3MC, and 6MCD, respectively. There were no differences in VL between 3MC vs. control and 6MCD vs. control, risk ratio (RR) = 1.00 (95% CI: 0.98 to 1.01) and RR = 1.00 (95% CI: 0.98 to 1.01), respectively. Conclusions There were no differences in retention and VL suppression for stable HIV-infected participants receiving multimonth dispensing of ART within community-based differentiated models when compared with the facility-based standard-of-care model.

Introduction Streptococcus pneumoniae is the leading cause of invasive bacterial disease, globally. Despite antiretroviral therapy, adults infected with human immunodeficiency virus (HIV) are also at high risk of pneumococcal carriage and disease. Pneumococcal conjugate vaccines (PCVs) provide effective protection against vaccine serotype (VT) carriage and disease in children, and have been introduced worldwide, including most HIV-affected low- and middle-income countries. Unlike high-income countries, the circulation of VT persists in the PCV era in some low-income countries and results in a continued high burden of pneumococcal disease in HIV-infected adults. Moreover, no routine vaccination that directly protects HIV-infected adults in such settings has been implemented. Areas covered Nonsystematic review on the pneumococcal burden in HIV-infected adults and vaccine strategies to reduce this burden. Expert opinion We propose and discuss the relative merit of changing the infant PCV program to use (1a) a two prime plus booster dose schedule, (1b) a two prime plus booster dose schedule with an additional booster dose at school entry, to directly vaccinate (2a) HIV-infected adults or vaccinating (2b) HIV-infected pregnant women for direct protection, with added indirect protection to the high-risk neonates. We identify key knowledge gaps for such an evaluation and propose strategies to overcome them.

Introduction In recent years, the lives of HIV-infected patients in Thailand have improved significantly due to continuous advances in treatment. However, the rate of cancer related to HIV infection (especially cervical cancer) is likely to increase. Although the World Health Organization (WHO) recommends Papanicolaou testing in all HIV-infected women, few of these patients receive this kind of screening in Thailand. Therefore, we conducted this study to evaluate the knowledge, attitudes, and practices of these patients with regard to cervical cancer screening. Materials and methods This cross-sectional study was conducted in HIV-infected women aged 18-65 years from April to November 2019 via a self-administered cervical cancer screening questionnaire, which consisted of four parts: demographic data, knowledge, attitudes, and practices. Results Three hundred HIV-infected women were recruited. Most of the participants had good attitudes toward screening and practiced adequate screening (75.3% and 71.3%, respectively). However, only 62 participants (20.7%) demonstrated adequate knowledge. The crucial factors that were associated with adequate screening practice were age 40-49 years-old (AOR =3.26, 95%CI=1.02-10.37), CD4 cell count (AOR = 3.41, 95%CI = 1.29-8.99), having been advised about cervical cancer screening (AOR= 6.23, 95%CI 1.84-21.07), and attitude toward screening (AOR= 5.7, 95%CI = 2.23-14.55). The major reasons for not undergoing screening were embarrassment (41.86%), lack of symptoms (41.86%), fear of the results (36.04%), and fear of pain (36.04%). Conclusion The reasons for inadequate testing were disregard and misconceptions about the procedure. To prevent invasive cervical lesions in HIV-infected women, health care providers should inform these patients about the importance of regular cervical cancer screening. .

MRI‐based neuroimaging techniques have been used to investigate brain injury associated with HIV‐infection. Whole‐brain cortical mean‐field dynamic modeling provides a way to integrate structural and functional imaging outcomes, allowing investigation of microscale brain dynamics. In this study, we adopted the relaxed mean‐field dynamic modeling to investigate structural and functional connectivity in 42 HIV‐infected subjects before and after 12‐week of combination antiretroviral therapy (cART) and compared them with 46 age‐matched healthy subjects. Microscale brain dynamics were modeled by a set of parameters including two region‐specific microscale brain properties, recurrent connection strengths, and subcortical inputs. We also analyzed the relationship between the model parameters (i.e., the recurrent connection and subcortical inputs) and functional network topological characterizations, including smallworldness, clustering coefficient, and network efficiency. The results show that untreated HIV‐infected individuals have disrupted local brain dynamics that in part correlate with network topological measurements. Notably, after 12 weeks of cART, both the microscale brain dynamics and the network topological measurements improved and were closer to those in the healthy brain. This was also associated with improved cognitive performance, suggesting that improvement in local brain dynamics translates into clinical improvement., In this study, we adopted the relaxed mean‐field dynamic modeling to investigate structural and functional connectivity in 42 HIV‐infected subjects before and after 12 week of combination antiretroviral therapy (cART) and compared them with 46 age‐matched healthy subjects.
