Abstract
OBJECTIVES AND METHODS : Progressive multifocal leukoencephalopathy (PML) has rarely been reported in people with HIV (PWH) with long-term HIV immune-virological control. We describe the clinical and biological characteristics of patients with confirmed PML among PWH with a CD4+ cell count more than 200 cells/μl and an undetectable HIV RNA viral load after at least 6 months of combined antiretroviral therapy (cART) at the time of PML diagnosis, in the large French multicenter Dat'AIDS cohort. RESULTS : Among 571 diagnoses of PML reported in the Dat'AIDS cohort between 2000 and 2019, 10 cases (1.75%) occurred in PWH with a CD4+ cell count greater than 200 cells/μl and an undetectable HIV RNA viral load after at least 6 months of cART. Median CD4+ cell count at PML diagnosis was 395 cells/μl (IQR 310-477). The median duration between the last detectable HIV viral load and the PML diagnosis was 41.1 months (IQR 8.2-67.4). Only one patient treated with rituximab-based chemotherapy for a large B-cell lymphoma had an established risk factor for PML. Among the nine other patients with no apparent severe immunodeficiency, multiple factors of impaired immunity could have led to the development of PML: hepatitis C virus (HCV) co-infection (n = 6), cirrhosis (n = 4), HHV-8 co-infection (n = 3) with Kaposi's sarcoma (n = 2) in association with Castleman's disease (n = 1) and indolent IgA multiple myeloma (n = 1). CONCLUSION : This study highlights that factors other than low CD4+ cell count and high HIV viral load may be associated with the occurrence of PML. Further studies are warranted to investigate in greater detail the immunologic characteristics of PWH with immune-virological control who develop PML.

Abstract
OBJECTIVES The aim of the study was to describe time trends in cancer incidence in people living with HIV (PLHIV) in Australia between 1982 and 2012. METHODS A population-based prospective study was conducted using data linkage between the national HIV and cancer registries. Invasive cancers identified in PLHIV were grouped into AIDS-defining cancers (ADCs), infection-related non-ADCs (NADCs), and non-infection-related NADCs. Crude and age-standardized incidence rates of cancers were calculated and compared over five time periods: 1982-1995, 1996-1999, 2000-2004, 2005-2008 and 2009-2012, roughly reflecting advances in HIV antiretroviral therapy. Standardized incidence ratios (SIRs) compared with the Australian general population were calculated for each time period. Generalized linear models were developed to assess time trends in crude and age-standardized incidences. RESULTS For ADCs, the crude and age-standardized incidences of Kaposi sarcoma and non-Hodgkin lymphoma substantially declined over time (P-trend < 0.001 for all) but SIRs remained significantly elevated. For infection-related NADCs, there were significant increases in the crude incidences of anal, liver and head and neck cancers. Age-standardized incidences increased for anal cancer (P-trend = 0.002) and liver cancer (P-trend < 0.001). SIRs were significantly elevated for anal cancer, liver cancer and Hodgkin lymphoma. For non-infection-related NADCs, the crude incidence of colorectal, lung and prostate cancers increased over time, but age-standardized incidences remained stable. CONCLUSIONS Continuous improvements and high coverage of antiretroviral therapy have reduced the incidence of ADCs in PLHIV in Australia. Clinical monitoring of anal and liver cancers in people living with HIV should be performed, given the increasing incidence of these cancers.

Abstract
The development of metabolic derangements as a result of HIV treatment has been an important area of research since the introduction of zidovudine in the 1980's. Antiretroviral therapy has intensely evolved in the last three decades, with new drugs gradually incorporated into everyday clinical practice. With the life expectancy of people living with HIV rapidly approaching that of their HIV-negative counterparts, the influence of these antiretrovirals on the development of the components of the metabolic syndrome remains of major interest to clinicians and their patients. In this review, we aimed to discuss the impact of cART on components of the metabolic syndrome, i.e., weight, plasma lipid levels, plasma glucose levels, and blood pressure, describing the influence of cART classes and of individual antiretrovirals. We also aimed to outline the limitations of the research conducted to date and the remaining knowledge gaps in this area.

Abstract
BACKGROUND HIV/AIDS is a multi-system disease that has been associated with several endocrinopathies including thyroid dysfunction. Thyroid dysfunction in patients with HIV/AIDS, among other factors, may arise from the direct cytopathic effects of HIV on the thyroid gland in addition to the adverse effects of highly active anti-retroviral drugs (HAART). STUDY OBJECTIVE The study aimed to determine the prevalence and pattern of thyroid dysfunction in HAART naïve HIV patients in Enugu. MATERIALS & METHODS Study was cross sectional, casecontrol based, involving 250 HAART naïve HIV sero-positive patients and 250 HIV sero-negative subjects. Anthropometric measurements and physical examination were done. Assay for fT3, fT4, TSH (for thyroid function) was done using the Enzyme Linked Immunoassay (ELISA) method. Data was analyzed using the Statistical Package for Social Sciences (SPSS) version 23. RESULTS The HAART naïve sero-positive cohorts comprised 112 males and 138 females while the control subjects consisted of 125 males and 125 females. Mean ages (years) of test and control groups were 38.84± 10.60 and 39.58 ±11.68 respectively. Prevalence of thyroid dysfunction among the study subjects was 36.4% and 7.6% in the controls. Subclinical hypothyroidism was the most common prevalent type of thyroid dysfunction in both test and control groups at 17.6% and 7.2% respectively. In the test group, sick euthyroid syndrome (17.2%) ranked second while in the controls, primary hypothyroidism (7.2%) was the second commonest dysfunction. CONCLUSION Thyroid dysfunction was more common in HAART-naïve HIV sero-positive subjects than in the general population with subclinical hypothyroidism emerging as the commonest abnormality.

Abstract
BACKGROUND The application of nanomedicine to antiretroviral drug delivery holds promise in reducing the comorbidities related to long-term systemic exposure to highly active antiretroviral therapy (HAART). However, the safety of drugs loaded with silver nanoparticles has been debatable. This study is aimed at evaluating the effects of HAART-loaded silver nanoparticles (HAART-AgNPs) on the behavioural assessment, biochemical indices, morphological, and morphometric of the hippocampus in diabetic Sprague-Dawley rats. METHODS Conjugated HAART-AgNPs were characterized using FTIR spectroscopy, UV spectrophotometer, HR-TEM, SEM, and EDX for absorbance peaks, size and morphology, and elemental components. Forty-eight male SD rats (250 ± 13 g) were divided into nondiabetic and diabetic groups. Each group was subdivided into (n = 8) A (nondiabetic+vehicle), B (nondiabetic+HAART), C (nondiabetic+HAART-AgNPs), D (diabetic+vehicle), E (diabetic+HAART), and F (diabetic+HAART-AgNPs). Morris water maze, Y-maze test, and weekly blood glucose levels were carried out. Following the last dose of 8-week treatment, the rats were anaesthetized and euthanized. Brain tissues were carefully removed and postfixed for Nissl staining histology. RESULTS 1.5 M concentration of HAART-AgNPs showed nanoparticle size 20.3 nm with spherical shape. HAART-AgNPs revealed 16.89% of silver and other elemental components of HAART. The diabetic control rats showed a significant increase in blood glucose, reduced spatial learning, positive hippocampal Nissl-stained cells, and a significant decrease in GSH and SOD levels. However, administration of HAART-AgNPs to diabetic rats significantly reduced blood glucose level, improved spatial learning, biochemical indices, and enhanced memory compared to diabetic control. Interestingly, diabetic HAART-AgNP-treated rats showed a significantly improved memory, increased GSH, SOD, and number of positive Nissl-stained neurons compared to diabetic-treated HAART only. CONCLUSION Administration of HAART to diabetic rats aggravates the complications of diabetes and promotes neurotoxic effects on the experimental rats, while HAART-loaded silver nanoparticle (HAART-AgNP) alleviates diabetes-induced neurotoxicity.

Abstract
Drug use implies important challenges related to HIV management, particularly due to an increased risk of potential interactions between antiretroviral therapy (ART) and illicit drugs (pDDIs). This study analyses the prevalence and severity of pDDIs among people living with HIV (PLHIV). It also explores their awareness of pDDIs and their beliefs about the toxicity that they may cause, as well as the impact of pDDIs on selected health variables. We conducted an on-line cross-sectional survey across 33 Spanish hospitals and NGOs to collect demographics and clinical data. pDDIs were checked against the Interaction Checker developed by Liverpool University. The sample of the present study was composed of 694 PLHIV who used illicit drugs. They represented 49.5% of the 1,401 PLHIV that participated in the survey. After excluding 38 participants due to lack of information on their ART or illicit drug use, 335 (51.1%) participants consuming drugs presented with some potentially significant pDDIs between their ART and illicit drugs, with a mean of 2.1±1.7 (1-10) pDDIs per patient. The drugs most frequently involved in pDDIs were cocaine, cannabis, MDMA and nitrates ("poppers"). The prevalence of pDDIs across ART regimens was: protease inhibitors (41.7%); integrase inhibitor-boosted regimens (32.1%), and non-nucleoside reverse transcriptase inhibitors (26.3%). An awareness of pDDIs and beliefs about their potential toxicity correlated positively with intentional non-adherence (p<0.0001). Participants with pDDIs exhibited a higher prevalence of intentional non-adherence (2.19±1.04 vs. 1.93±0.94; p = 0.001). The presence of pDDIs was not associated with poorer results in the clinical variables analysed. A significant proportion of PLHIV who use drugs experience pDDIs, thereby requiring close monitoring. pDDIs should be considered in the clinical management of HIV patients. Adequate information about pDDIs and indicators about how to manage ART when PLHIV use drugs could improve ART non-adherence.

Abstract
Abdominal pain in an immunocompromised patient represents a common clinical scenario that may have uncommon causes. Evaluation relies first on identifying the immunocompromise, whether due to congenital immunodeficiencies, malignancy, hematopoietic stem cell transplant, solid organ transplant, or human immunodeficiency virus/acquired immunodeficiency syndrome. Based on this determination, the emergency physician may then build a focused differential of pathophysiologic possibilities. Careful evaluation is necessary given the absence of classic physical examination findings, and liberal use of laboratory and cross-sectional imaging is prudent. Conservative evaluation and disposition of these high-risk patients is important to consider.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) infection and highly active antiretroviral therapy (HAART) are implicated in cardiovascular diseases. The objective of this study was to evaluate the clinical and echocardiographic findings in HIV-infected adults. METHODS One hundred HIV subjects on HAART, 100 HAART-naïve patients and 100 controls were recruited in this cross-sectional study. RESULTS Mean CD4 cell count was significantly higher in the HAART-exposed (408.43 ± 221.62) than the HAART-naïve groups (250.06 ± 154.26) (p < 0.001). Weight loss (49%), skin lesions (14%), body weakness (24%), oral thrush (10%) and lymphadenopathy (10%) were more prevalent in HAART-naïve patients (p < 0.05). Dimensions of aortic root (2.71 cm), left atrium (3.27 cm) and left ventricular mass index (79.95) were significantly higher in HIV-positive subjects on HAART (p < 0.05). CONCLUSIONS Clinical features of HIV and the CD4 nadir were more prevalent in the HIV-positive, HAART-naïve subjects. Dimensions of the aortic root, left atrium and left ventricle were relatively larger in the HAART-exposed patients while wall thickness and ejection fraction were higher in the HAART-naïve subjects.

Abstract
BACKGROUND Hypertension (HTN) and HIV are salient risk factors for cerebral small vessel disease and neurocognitive (NC) impairment, yet the effects of HTN on NC performance in persons living with HIV remain poorly understood. This is the first study to examine the longitudinal associations between blood pressure (BP), HTN, and pulse pressure (PP) with NC performance in persons living with HIV. SETTING New York City. METHODS Analysis of medical, NC, and virologic data from 485 HIV+ participants was collected by the Manhattan HIV Brain Bank, a prospective, observational, longitudinal study of neuroHIV. A series of multilevel linear growth curve models with random intercepts and slopes were estimated for BP, HTN status, and PP to predict the change in NC performance. RESULTS The baseline prevalence of HTN was 23%. Longitudinal changes in diastolic and systolic pressure were associated with a 10.5-second and 4-second increase in the Grooved Pegboard Test nondominant hand performance, respectively. A longitudinal change in diastolic BP was also associated with a 0.3-point decline in correct categories and 3-point increase in perseverative responses and total errors on the Wisconsin Card Sorting Test. Increasing odds of prevalent and/or incident HTN were associated with a 0.1-point decrease in correct categories and a 0.8-point increase in total errors on the Wisconsin Card Sorting Test. There was no association between PP and NC performance. CONCLUSIONS The results indicate linear longitudinal relations for BP and HTN with poorer NC test performance, particularly in psychomotor and executive functions in persons with HIV.

Abstract
BACKGROUND Symptoms associated with menstruation and endometriosis are common amongst women of reproductive ages and the pathogenesis of these illnesses is postulated to be associated with aberrations in endometrial regeneration, immune response and in endometrial stem cell function. Highly active antiretroviral therapy (HAART) has been shown to enhance events seen in biological aging of tissues, with HIV/AIDS patients enduring the premature appearance of illnesses associated with stem-cell aging. Considering the intricate relationship between dysregulation of stem cell function, in both HAART therapy and in menstrual disorders/endometriosis, we sought to examine the prevalence of menstrual related symptoms (MRS) associated with endometriosis in women on HIV/AIDS therapy. METHODS A menstrual related symptoms (MRS) questionnaire adapted from the British Society of Gynaecological Endoscopists (BSGE) pelvic pain questionnaire, which has been used in both clinical and research setting, was completed by 100 women living with HIV (WLWH) attending a specialist HIV clinic and by 100 women without a diagnosis of HIV attending the Sexual Health clinic (WWH). HIV related demographic details, including results from recent blood tests, were also recorded prospectively from the WLWH. RESULTS WLWH were slightly older (37.7 vs. 34.8 years, P = 0.01); with higher BMI (28.9 vs. 24.8, P < 0.001); and were likely to be parous (85% vs. 54% P < 0.001) and non-Caucasian (79% vs 18%) compared with WWH. Most women in both groups had regular periods (77.9% vs. 74.7%), and WLWH were more likely to have a shorter duration of bleeding compared with WWH (81.4% vs 69.3% P = 0.05). However, WLWH were more likely to suffer with pre-menstrual tension compared with WWH (60.8% vs 50.6% P = 0.01). CONCLUSION Our data suggests that WLWH, despite being older and of higher BMI, have a shorter duration of menstrual bleeding, and we hypothesise that this may possibly be due to the (beneficial) side effects of some HAART components. Further research is needed to explore the effect of HAART on MRS to determine if these therapies could be used in the future as a fertility retaining treatment for MRSs/endometriosis.

Abstract
We report a case of Mycobacterium avium complex immune reconstitution inflammatory syndrome (MAC-IRIS) in a patient with HIV positive. Initial presentation was that of a purpuric purple macular rash in-keeping with Kaposi sarcoma as an AIDS defining illness. Three weeks following the initiation of antiretroviral treatment (ART) she developed chest pain, dry cough and fever. A diagnosis of MAC was made through imaging and sputum cultures and appropriate treatment was initiated. Despite adequate management with evidence of good immunological and virological response, the patient represented with persistent symptoms. Repeat CT of the chest confirmed worsening lymphadenopathy with necrosis. Given these findings, a diagnosis of MAC-IRIS was made with resolution of fever after corticosteroids were initiated. This case highlights the importance of considering MAC as a cause of IRIS in severely immunosuppressed patients with HIV.

Abstract
OBJECTIVES This study aimed to identify adverse drug reactions (ADRs) attributable to tenofovir (TDF)- and zidovudine (AZT)-based fixed-dose combinations of highly active antiretroviral (ARV) therapy and subsequently determine the annual costs incurred in managing these ADRs and the budget implications in an outpatient ARV clinic in Mamelodi, Pretoria. METHODS This retrospective cohort study reviewed deidentified clinical data for ADRs. Medical charts of human immunodeficiency virus-positive patients, who were receiving either TDF- or AZT-based fixed-dose combinations of ARV therapy, were analyzed. Costs were converted to US dollars using the rate of US$1 equivalent to ZAR14.3853. Based on the costs and the incidence rates of ADRs observed in the analysis, a decision tree model was established to estimate the cost impact of ADR management on the clinic's budget. RESULTS A total of 469 patient files were analyzed (62% female vs 38% male). The mean age at the start of ARV therapy for the cohort was 36.6 years (95% confidence interval 35.74-37.45), and the mean baseline CD4 count was 380 (95% confidence interval 343-418). The incidence of ADRs to TDF- or AZT-based fixed-dose combinations of ARV therapy was found to be 24.95%. The study revealed that US$29.70 was the cost attributed to ADRs owing to TDF-based regimens, whereas US$32.53 was the cost attributed to ADRs owing to AZT-based regimens, per patient, annually. Costs attributed to gastrointestinal-related ADRs were the highest in comparison with other ADRs. The estimated total cost of ADRs attributed to AZT-based therapy was US$556.40, and the estimated total cost of ADRs attributed to TDF-based ARV therapy per annum was US$2348.80 for the 1221 patients who started receiving ARV therapy between July 2017 and June 2018 at the clinic. CONCLUSIONS Despite the estimated costs related to ADRs in the study being lower than those in similar studies, there remains a notable budget impact, particularly in a resource-limited setting. The study findings allow for improved budget forecasts in an ARV clinic setting.

Maternal HIV Infection and Spontaneous Versus Provider-Initiated Preterm Birth in an Urban Zambian Cohort. J Acquir Immune Defic Syndr 2021; 87:860-868. [PMID: 33587508 PMCID: PMC8131221 DOI: 10.1097/qai.0000000000002654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Accepted: 01/11/2021] [Indexed: 10/22/2022]
Abstract
OBJECTIVE We investigated the effect of maternal HIV and its treatment on spontaneous and provider-initiated preterm birth (PTB) in an urban African cohort. METHODS The Zambian Preterm Birth Prevention Study enrolled pregnant women at their first antenatal visit in Lusaka. Participants underwent ultrasound, laboratory testing, and clinical phenotyping of delivery outcomes. Key exposures were maternal HIV serostatus and timing of antiretroviral therapy initiation. We defined the primary outcome, PTB, as delivery between 16 and 37 weeks' gestational age, and differentiated spontaneous from provider-initiated parturition. RESULTS Of 1450 pregnant women enrolled, 350 (24%) had HIV. About 1216 (84%) were retained at delivery, 3 of whom delivered <16 weeks. Of 181 (15%) preterm deliveries, 120 (66%) were spontaneous, 56 (31%) were provider-initiated, and 5 (3%) were unclassified. In standardized analyses using inverse probability weighting, maternal HIV increased the risk of spontaneous PTB [RR 1.68; 95% confidence interval (CI): 1.12 to 2.52], but this effect was mitigated on overall PTB [risk ratio (RR) 1.31; 95% CI: 0.92 to 1.86] owing to a protective effect against provider-initiated PTB. HIV reduced the risk of preeclampsia (RR 0.32; 95% CI: 0.11 to 0.91), which strongly predicted provider-initiated PTB (RR 17.92; 95% CI: 8.13 to 39.53). The timing of antiretroviral therapy start did not affect the relationship between HIV and PTB. CONCLUSION The risk of HIV on spontaneous PTB seems to be opposed by a protective effect of HIV on provider-initiated PTB. These findings support an inflammatory mechanism underlying HIV-related PTB and suggest that published estimates of PTB risk overall underestimate the risk of spontaneous PTB.

Abstract
INTRODUCTION highly active antiretroviral therapy (HAART) has contributed to a reduction in HIV- related oral lesions and improved quality of life among HIV seropositive patients. However, the therapy is not without its side effects. This study was aimed at assessing the self- reported orofacial manifestations due to long term use of HAART, as well as the pattern of oral lesions on examination. METHODS this was a cross-sectional study conducted among HIV seropositive adult patients in Ibadan, who had been on HAART for at least two years. Data were collected using an interviewer-administered questionnaire. Clinical diagnosis of HIV-related oral lesions was made according to the EC-Clearinghouse criteria. Data analysis was done using SPSS version 25. RESULTS the study participants comprised of 227 HIV seropositive patients who were HAART experienced, with 54 (24%) males and 173 (76%) females. Their mean age (±SD) was 44.7 (±9.4) years. The participants CD4 count ranged from 13-1338cells/mm3, with a median count of 341 cells/mm3. About half (45%) of the participants noted one or more orofacial changes since they commenced HAART. These oral changes included dryness of mouth, burning sensation, abnormal taste, melanotic hyperpigmentation, oral thrush, ulcers, and parotid swelling. Most of those who reported oral changes had been on HAART over 10 years (p=0.03), and the changes were more reported among those on the first-line regimen. CONCLUSION melanotic hyperpigmentation was the most common oral lesion found and burning mouth syndrome was the most commonly reported complain among HIV-seropositive adults who are on long-term HAART.

Abstract
BACKGROUND Anemia is one of the most common hematological problems in HIV infected patients in the world. The main aim of this study was to determine the magnitude of anemia and associated factors among HIV infected children on highly active antiretroviral therapy attending University of Gondar Comprehensive and Specialized Referral Hospital. METHODS A retrospective study was conducted from 2013 to 2018 by reviewing medical records at University of Gondar Comprehensive and Specialized Referral Hospital ART clinic. Records of 238 HIV infected children on HAART were selected using a convenient sampling technique. Socio-demographic characteristics, clinical information, and hematological and immunological profiles of the study participants were collected from the patients record books. WHO cutoff value of hemoglobin was taken and adjusted to define anemia in higher altitude. Data was analyzed by using the SPSS version 20 statistical software, and odds ratios with 95% confidence intervals were used to quantify the strength of association between anemia and its potential predictors. RESULTS The overall prevalence of anemia among HIV infected children in this study was 38.7%. Of anemic children, 48.9% had mild, 39.1% moderate, and 11.9% severe anemia. This study showed that HIV infected children on Highly Active Antiretroviral Therapy who live in rural residence had a two-fold risk of being anemia than urban dwellers (AOR = 2.151, 95% CI, 1.123 - 4.122). There was no significant association with gender, WHO clinical stage, opportunistic infections, cotrimoxazole treatment, and CD4 count percentage. CONCLUSIONS Anemia is a common problem among the children taking highly active antiretroviral therapy. Therefore, health care workers need to routinely investigate and treat anemia, especially in rural dwellers. Furthermore, large scale and longitudinal studies are recommended to strengthen and explore the problem in depth.

Abstract
BACKGROUND Anti-retroviral treatment enhances the immune status and reduces unwanted outcomes. However, development of treatment failure and drug resistance raises concern over lifelong treatments to chronic diseases such as HIV/AIDS. OBJECTIVES This study determined proportion of treatment failure (TF) and identified factors associated with TF among people living with human immunodeficiency virus (HIV) in Bahir Dar, Northwest Ethiopia. METHODS Facility based cross sectional study was carried out from November, 2017 to April, 2018. Sociodemographic and clinical data were collected using structured questioner. Blood sample was collected and analyzed for viral load, complete blood count (CBC), liver and kidney function test and CD4 count. A patient is declared as treatment failure when viral load value is higher than 1000 RNA copies/ml in two consecutive viral load analyses within three months interval. Data were entered and analyzed using SPSS version 23. To identify factors associated with TF, logistic regressions model was employed. RESULTS A total of 430 people who had six months and above antiretroviral treatment (ART) follow up were enrolled in the study. Of these, 57.9% were females & the mean age was 38 years. The mean month of ART follow up was 83 months. In the first viral load analysis, 106 (24.7%) of the cohort were virologically failed. These failed people were followed for 3 months with intensive adherence support; then second viral load analysis showed a viralogical failure among 65 people of the second cohort. Thus, the overall viralogical failure or TF was 15.1%. The re-suppression rates were 41(38.7%). Male gender, people with history of drug discontinuation, poor adherence, irregular time of drug intake, multiple sexual practice showed significant association with TF. Moreover, base line and current CD4 counts of <200 cells/ml also demonstrated significant association with TF. CONCLUSION Significant proportion of treatment failure was reported in the present study. Moreover, behavioral factors such as drug discontinuation, poor adherence, multiple sexual partner were associated with treatment failure. Hence, to avoid TF, regular patient counseling and monitoring should be in place. To identify the predictors for treatment failure, further follow-up study is desirable.

Abstract
INTRODUCTION highly active antiretroviral therapy (HAART) has led to a decline in HIV-induced morbidity and mortality in recent years. However, it has been opined that this has led to elevated risks of cardiovascular diseases (CVDs). This study assessed the risks of CVDs among HAART experienced individuals living with HIV. METHODS a cross sectional study involving 196 adults consisting of 118 HAART experienced and 78 HAART naïve was conducted. Anthropometric and blood pressure measurements were recorded for all participants. Blood samples obtained from the volunteers were used to determine glucose, creatinine, HIV viral load, CD4 count and lipid profile using standard methods. Lipid ratios, atherogenic indices and QRISK3 risk score were calculated. RESULTS the median CD4 lymphocyte, mean body mass index (BMI) and HDL-c in HAART experienced participants were higher (P<0.05) than HAART naive individuals. The QRISK3 risk score and creatinine were higher (p<0.05) among HAART experienced group. In HAART experienced group, the risk of hypertension, increased low-density lipoprotein (LDL-c), atherogenic index of plasma (AIP) and QRISK3 were 3.7, 2.0, 2.38 and 3.85 times (p<0.05) higher respectively than in HAART naive. Atherogenic coefficient (AC) increase was more prevalent among male (p<0.05) participants. Risk of chronic renal disease (eGFR), hypertension and CVD (as measured by QRISK3) was higher (p<0.05) among the female and older participants respectively. CONCLUSION the risk of CVDs and renal disease appeared to be higher among HAART experienced volunteers and older (>45 years) volunteers. The risk of renal disease appeared higher in females.

Abstract
BACKGROUND Dolutegravir has been widely available in Brazil since 2017. Following the signal that infants born to women with dolutegravir exposure at conception in Botswana had a higher risk of neural tube defects (NTDs), public health leaders initiated a national investigation to evaluate periconception dolutegravir exposure among all pregnant Brazilian women with HIV and its potential association with risk of NTDs, stillbirth, or miscarriage before 22 weeks (also called spontaneous abortion). METHODS In this retrospective, observational, national, cohort study, we identified all women with pregnancies and possible dolutegravir exposure within 8 weeks of estimated date of conception between Jan 1, 2017, and May 31, 2018, and approximately 3:1 matched pregnant women exposed to efavirenz between Jan 1, 2015, and May 31, 2018, using the Brazilian antiretroviral therapy database. We did detailed chart reviews for identified women. The primary outcomes were NTD and a composite measure of NTD, stillbirth, or miscarriage. NTD incidences were calculated with 95% CI. The composite outcome was examined with logistic regression using propensity score matching weights to balance confounders. FINDINGS Of 1427 included women, 382 were exposed to dolutegravir within 8 weeks of estimated date of conception. During pregnancy, 183 (48%) of 382 dolutegravir-exposed and 465 (44%) of 1045 efavirenz-exposed women received folic acid supplementation. There were 1452 birth outcomes. There were no NTDs in either dolutegravir-exposed (0, 95% CI 0-0·0010) or efavirenz-exposed groups (0, 95% CI 0-0·0036). There were 23 (6%) stillbirths or miscarriages in 384 dolutegravir-exposed fetuses and 28 (3%) in the 1068 efavirenz-exposed fetuses (p=0·0037). Logistic regression models did not consistently indicate an association between dolutegravir exposure and risk of stillbirths or miscarriages. After study closure, two confirmed NTD outcomes in fetuses with periconception dolutegravir exposure were reported to public health officials. An updated estimate of NTD incidence incorporating these cases and the estimated number of additional dolutegravir-exposed pregnancies between Jan 1, 2015 and Feb 28, 2019, is 0·0018 (95% CI 0·0005-0·0067). INTERPRETATION Neither dolutegravir nor efavirenz exposure was associated with NTDs in our national cohort; incidence of NTDs is probably well under 1% in dolutegravir-exposed HIV-positive women but still slightly above HIV-uninfected women (0·06%) in Brazil.

Abstract
HIV can evolve remarkably quickly in response to antiretroviral therapies and the immune system. This evolution stymies treatment effectiveness and prevents the development of an HIV vaccine. Consequently, there has been a great interest in using population genetics to disentangle the forces that govern the HIV adaptive landscape (selection, drift, mutation, and recombination). Traditional population genetics approaches look at the current state of genetic variation and infer the processes that can generate it. However, because HIV evolves rapidly, we can also sample populations repeatedly over time and watch evolution in action. In this paper, we demonstrate how time series data can bound evolutionary parameters in a way that complements and informs traditional population genetic approaches. Specifically, we focus on our recent paper (Feder et al., 2016, eLife), in which we show that, as improved HIV drugs have led to fewer patients failing therapy due to resistance evolution, less genetic diversity has been maintained following the fixation of drug resistance mutations. Because soft sweeps of multiple drug resistance mutations spreading simultaneously have been previously documented in response to the less effective HIV therapies used early in the epidemic, we interpret the maintenance of post-sweep diversity in response to poor therapies as further evidence of soft sweeps and therefore a high population mutation rate (θ) in these intra-patient HIV populations. Because improved drugs resulted in rarer resistance evolution accompanied by lower post-sweep diversity, we suggest that both observations can be explained by decreased population mutation rates and a resultant transition to hard selective sweeps. A recent paper (Harris et al., 2018, PLOS Genetics) proposed an alternative interpretation: Diversity maintenance following drug resistance evolution in response to poor therapies may have been driven by recombination during slow, hard selective sweeps of single mutations. Then, if better drugs have led to faster hard selective sweeps of resistance, recombination will have less time to rescue diversity during the sweep, recapitulating the decrease in post-sweep diversity as drugs have improved. In this paper, we use time series data to show that drug resistance evolution during ineffective treatment is very fast, providing new evidence that soft sweeps drove early HIV treatment failure.

Abstract
Introduction The use of patient-reported outcomes (PROs) to systematically quantify adverse events (AE) will assist in the improvement of medical care and the QoL of patients living with HIV (PLWH). The aim of this study was to investigate the associations between self-reported side effects and other PROs, demographics and laboratory data, and further evaluate the Health Questionnaire (HQ) as a tool for following trends in patient-reported side effects over time in relation to trends in prescribed third agent in ART. Materials and methods The Swedish National Registry InfCareHiv includes an annual self-reported nine-item HQwhich is used in patient-centered HIV care in all Swedish HIV units. In this study, the experience of side effects was addressed. We analyzed 9,476 HQs completed by 4,186 PLWH together with details about their prescribed ART and relevant biomarkers collected during 2011–2017. Data were analyzed using descriptive statistics, Pearson’s correlation coefficient and mixed logistic regression. Results The cross-sectional analysis of the HQs showed that the frequency of reported side effects decreased from 32% (2011) to 15% (2017). During the same period, there was a shift in ART prescription from efavirenz (EFV) to dolutegravir (DTG) (positive correlation coefficient r = 0.94, p = 0.0016). Further, PLWH who reported being satisfied with their physical health (OR: 0.47, p = <0.001) or psychological health (OR: 0.70, p = 0.001) were less likely to report side effects than those less satisfied. Conclusions Self-reported side effects were found to have a close relationship with the patient’s ratings of their overall health situation and demonstrated a strong correlation with the sharp decline in use of EFV and rise in use of DTG, with reported side effects being halved. This study supports the feasibility of using the HQ as a tool for longitudinal follow up of trends in PROs.
