The prevalence of comorbidities among people living with HIV in Brent: a diverse London Borough

Effect of dolutegravir on weight changes and lipid profile compared with efavirenz in people living with HIV: A retrospective cohort study

BACKGROUND

There are limited data on DTG-associated weight gain among treatment-naïve Asian people living with HIV (PLHIV).

METHODS

Eighty-one and 100 PLHIV initiating DTG-based and efavirenz (EFV)-based antiretroviral therapy (ART), respectively, were retrospectively investigated for weight changes and lipid profiles at 6 and 12 months after ART initiation.

RESULTS

At baseline, the DTG group had a lower mean body weight (BW) (60.7 kg vs. 64.3 kg, p = 0.071) and lower mean cholesterol level (172 mg/dL vs. 185 mg/dL, p = 0.029) than the EFV group. Mean BW remained lower in the DTG group than in the EFV group at 6 [58.2 kg vs. 66.0 kg, mean difference (MD) -7.8, p = 0.005] and 12 (59.6 kg vs. 67.0 kg, MD -7.3, p = 0.008) months. BW did not significantly change between baseline and 12 months in the DTG group (60.7 kg vs. 59.6 kg, p = 0.495), whereas it significantly increased between baseline and 12 months in the EFV group (64.3 kg vs. 66.9 kg, p = 0.019). Cholesterol levels did not significantly increase between baseline and 12 months in either group. After adjustment, DTG use [MD -5.85, 95 % confidence interval (CI) -10.45, -1.24, p = 0.013] and baseline BW (MD 0.97, 95 % CI 0.79, 1.15, p < 0.001) were significantly associated with BW changes over time.

CONCLUSIONS

DTG-based ART was not significantly associated with increased BW and cholesterol levels compared with EFV-based ART in treatment-naïve Thai PLHIV.

Correlates of internalized stigma and antiretroviral therapy adherence among people living with HIV in the Volta region of Ghana

OBJECTIVE

HIV-related stigma is a major public health concern compromising the rights and health outcomes of many people living with HIV (PLWH). Its reduction is said to be critical in strengthening the continuous efforts targeted at preventing and controlling HIV, as it directly impacts antiretroviral treatment adherence. This study examines the association between HIV-related stigma and adherence to antiretroviral therapy (ART) among PLWH in one of the 16 administrative regions of Ghana, Africa.

METHODS

This descriptive cross-sectional study employed a survey to assess the factors affecting the utilization of ART among PLWH (n = 155) in the Volta region. The Center for Support Evaluation adherence index and internalized stigma of AIDS Tool were used to collect data on medication adherence and stigma, respectively. Data was analyzed using R statistical analysis software. Logistic regression models were performed to ascertain the predictors of ART utilization among PLWH.

RESULTS

A greater proportion (70%) of the study's participants reported adherence to ART. We found a positive association between HIV-related internalized stigma and medication adherence such that reporting high levels of stigma on average was associated with high levels of medication adherence [OR = 1.08, 95% CI:1.01, 1.15]. Older age was related to higher adherence while reporting more depressive symptoms was associated with low medication adherence.

CONCLUSION

Our findings show that stigma may serve as a facilitator instead of a barrier to adhering to antiretroviral medication. Although this contradicts common narratives about stigma's destructive effect, it is possible to promote good health-seeking behavior when the fear component of stigma is considered. To encourage medication adherence towards meeting UNAIDS' 95-95-95 agenda and better understand stigma's role, further research is required.

Comparison of the quality of life of comorbid and non-comorbid people living with HIV/AIDS in a Nigerian secondary healthcare facility

Introduction

Quality of life (QoL) is a vital healthcare indicator among people living with human immunodeficiency virus (PLWHA). Assessing the effects of comorbidities on QoL among PLWHA is of clinical and public health importance. This study compared the QoL of comorbid and non-comorbid PLWHA at St. Gerard's Catholic Hospital (SGCH), Kaduna.

Methods

This was a prospective cross-sectional study of 178 conveniently selected and stratified comorbid PLWHA and 172 non-comorbid PLWHA receiving care at the facility. Data was collected using a structured, interviewer-administered instrument. The QoL scores were statistically compared using the Mann‒Whitney U test. P<0.05 was considered statistically significant for all the analyses.

Results

Most respondents were aged 35 - 54 years (65.2% and 66.4% for comorbid and non-comorbid patients respectively), were female (70.8% and 69.2% for comorbid and non-comorbid patients respectively) and married (67.4% and 59.3% for comorbid and non-comorbid patients respectively). For all QoL domains (perception of QoL and general health, physical health, psychological health, level of independence, social relationship, environment, and spirituality/religion/personal beliefs), there was evidence the distribution of values was significantly lower in the comorbid PLWHA compared to the non-comorbid PLWHA (p<0.001), with the largest difference seen for physical health. The mean physical health (interquartile range) was 9 (7-10) and 17 (15-19) for comorbid and non-comorbid PLWHA respectively. The most prevalent comorbidities among the PLWHA were hypertension 97 (54.49%) and diabetes 36 (20.22%).

Conclusion

Non-comorbid PLWHA had better QoL than comorbid PLWHA in all the QoL domains and the greatest difference was observed in physical health. Special efforts should be made to improve the QoL of comorbid PLWHA.

What are the predictors of change in multimorbidity among people with HIV? A longitudinal observational cohort study

INTRODUCTION

Multimorbidity is common among people living with HIV (PLWH), with numerous cross-sectional studies demonstrating associations with older age and past immunosuppression. Little is known about the progression of multimorbidity, particularly in the setting of long-term access to antiretrovirals. This study aims to determine factors predictive of change in multimorbidity in PLWH.

METHODS

People living with HIV who attended a regional HIV service were recruited to a consented observational cohort between September 2016 and March 2020. Demographic data, laboratory results and a Cumulative Illness Rating Scale (CIRS) were collected at enrolment and first clinical review of every subsequent year. Change in CIRS score was calculated from enrolment to February 2021. Associations with change were determined through univariate and multivariate linear regression.

RESULTS

Of 253 people, median age was 58.9 [interquartile range (IQR): 51.9-64.4] years, 91.3% were male, and HIV was diagnosed a median of 22.16 years (IQR: 12.1-30.9) beforehand. Length of time in the study was a median of 134 weeks (IQR: 89.0-179.0), in which a mean CIRS score change of 1.21 (SD 2.60) was observed. Being older (p < 0.001) and having a higher body mass index (p = 0.008) and diabetes (p = 0.014) were associated with an increased likelihood of worsening multimorbidity. PLWH with a higher level of multimorbidity at baseline were less likely to worsen over time (p < 0.001).

CONCLUSION

As diabetes and weight predict worsening multimorbidity, routine diabetes screening, body mass index measurement, and multimorbidity status awareness are recommended.

Elucidating the role of extracellular vesicles in liver injury induced by HIV

INTRODUCTION

Liver disease is known as one of the leading co-morbidities in HIV infection, with 18% of non-AIDS-related mortality. There is constant crosstalk between liver parenchymal (hepatocytes) and non-parenchymal cells (macrophages, hepatic stellate cells, endothelial cells), and extracellular vesicles (EVs) are one of the most important ways of cell-to-cell communication.

AREAS COVERED

We briefly cover the role of EVs in liver disease as well as what is known about the role of small EVs, exosomes, in HIV-induced liver disease potentiated by alcohol as one of the second hits. We also touch large EVs, apoptotic bodies (ABs), in HIV-induced liver injury, the mechanisms of their formation and potentiation by second hits, and their role in the progression of liver disease.

EXPERT OPINION/COMMENTARY

Liver cells are an important source of EVs, which may provide the connection between different organs via secretion into the circulating blood (exosomes) or serve for the communication between the cells within the organ (ABs). Understanding the role of liver EVs in HIV infection and the involvement of second hits in EV generation would provide a new angle for the analysis of HIV-related liver disease pathogenesis and progression to end-stage liver disease.

The Impact of COVID-19 on People Living with HIV-1 and HIV-1-Associated Neurological Complications

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the causative pathogen of the coronavirus disease 2019 (COVID-19) pandemic, a fatal respiratory illness. The associated risk factors for COVID-19 are old age and medical comorbidities. In the current combined antiretroviral therapy (cART) era, a significant portion of people living with HIV-1 (PLWH) with controlled viremia is older and with comorbidities, making these people vulnerable to SARS-CoV-2 infection and COVID-19-associated severe outcomes. Additionally, SARS-CoV-2 is neurotropic and causes neurological complications, resulting in a health burden and an adverse impact on PLWH and exacerbating HIV-1-associated neurocognitive disorder (HAND). The impact of SARS-CoV-2 infection and COVID-19 severity on neuroinflammation, the development of HAND and preexisting HAND is poorly explored. In the present review, we compiled the current knowledge of differences and similarities between SARS-CoV-2 and HIV-1, the conditions of the SARS-CoV-2/COVID-19 and HIV-1/AIDS syndemic and their impact on the central nervous system (CNS). Risk factors of COVID-19 on PLWH and neurological manifestations, inflammatory mechanisms leading to the neurological syndrome, the development of HAND, and its influence on preexisting HAND are also discussed. Finally, we have reviewed the challenges of the present syndemic on the world population, with a particular emphasis on PLWH.

HIV Promotes Atherosclerosis via Circulating Extracellular Vesicle MicroRNAs

People living with HIV (PLHIV) are at a higher risk of having cerebrocardiovascular diseases (CVD) compared to HIV negative (HIVneg) individuals. The mechanisms underlying this elevated risk remains elusive. We hypothesize that HIV infection results in modified microRNA (miR) content in plasma extracellular vesicles (EVs), which modulates the functionality of vascular repairing cells, i.e., endothelial colony-forming cells (ECFCs) in humans or lineage negative bone marrow cells (lin- BMCs) in mice, and vascular wall cells. PLHIV (N = 74) have increased atherosclerosis and fewer ECFCs than HIVneg individuals (N = 23). Plasma from PLHIV was fractionated into EVs (HIVposEVs) and plasma depleted of EVs (HIV PLdepEVs). HIVposEVs, but not HIV PLdepEVs or HIVnegEVs (EVs from HIVneg individuals), increased atherosclerosis in apoE-/- mice, which was accompanied by elevated senescence and impaired functionality of arterial cells and lin- BMCs. Small RNA-seq identified EV-miRs overrepresented in HIVposEVs, including let-7b-5p. MSC (mesenchymal stromal cell)-derived tailored EVs (TEVs) loaded with the antagomir for let-7b-5p (miRZip-let-7b) counteracted, while TEVs loaded with let-7b-5p recapitulated the effects of HIVposEVs in vivo. Lin- BMCs overexpressing Hmga2 (a let-7b-5p target gene) lacking the 3'UTR and as such is resistant to miR-mediated regulation showed protection against HIVposEVs-induced changes in lin- BMCs in vitro. Our data provide a mechanism to explain, at least in part, the increased CVD risk seen in PLHIV.

Assessing and Reassessing the Association of Comorbidities and Coinfections in COVID-19 Patients

Coronavirus disease 2019 (COVID-19) has posed an enormous global health and economic burden. To date, 324 million confirmed cases and over 5.5 million deaths have been reported. Several studies have reported comorbidities and coinfections associated with complicated and serious COVID-19 infections. Data from retrospective, prospective, case series, and case reports from various geographical locations were assessed, which included ~ 2300 COVID-19 patients with varying comorbidities and coinfection. We report that Enterobacterales with Staphylococcus aureus was the most while Mycoplasma pneumoniae was the least prevalent coinfection in COVID-19 patients with a comorbidity. In this order, hypertension, diabetes, cardiovascular disease, and pulmonary disease were the prevalent comorbidities observed in COVID-19 patients. There was a statistically significant difference in the prevalent comorbidities observed in patients coinfected with Staphylococcus aureus and COVID-19 and a statistically non-significant difference in the prevalent comorbidities in patients coinfected with Mycoplasma pneumoniae and COVID-19 as compared to similar infections in non-COVID-19 coinfection. We report a significant difference in the prevalent comorbidities recorded in COVID-19 patients with varying coinfections and varying geographic study regions. Our study provides informative data on the prevalence of comorbidities and coinfections in COVID-19 patients to aid in evidence-based patient management and care.

Hepatocyte-Specific Triggering of Hepatic Stellate Cell Profibrotic Activation by Apoptotic Bodies: The Role of Hepatoma-Derived Growth Factor, HIV, and Ethanol

Liver disease is one of the leading comorbidities in HIV infection. The risk of liver fibrosis development is potentiated by alcohol abuse. In our previous studies, we reported that hepatocytes exposed to HIV and acetaldehyde undergo significant apoptosis, and the engulfment of apoptotic bodies (ABs) by hepatic stellate cells (HSC) potentiates their pro-fibrotic activation. However, in addition to hepatocytes, under the same conditions, ABs can be generated from liver-infiltrating immune cells. The goal of this study is to explore whether lymphocyte-derived ABs trigger HSC profibrotic activation as strongly as hepatocyte-derived ABs. ABs were generated from Huh7.5-CYP2E1 (RLW) cells and Jurkat cells treated with HIV+acetaldehyde and co-culture with HSC to induce their pro-fibrotic activation. ABs cargo was analyzed by proteomics. ABs generated from RLW, but not from Jurkat cells activated fibrogenic genes in HSC. This was driven by the expression of hepatocyte-specific proteins in ABs cargo. One of these proteins is Hepatocyte-Derived Growth Factor, for which suppression attenuates pro-fibrotic activation of HSC. In mice humanized with only immune cells but not human hepatocytes, infected with HIV and fed ethanol, liver fibrosis was not observed. We conclude that HIV+ABs of hepatocyte origin promote HSC activation, which potentially may lead to liver fibrosis progression.

Health-related quality of life and associated factors among cancer patients in Ethiopia: Systematic review and meta-analysis

INTRODUCTION

Cancer is the main cause of morbidity and mortality in every part of the world, regardless of human development. Cancer patients exhibit a wide range of signs and symptoms. Being diagnosed with cancer has a variety of consequences that can affect one's quality of life. The term "health-related quality of life" refers to a multidimensional concept that encompasses a person's whole health. The availability of data on the prevalence of poor quality of life among cancer patients in Ethiopia is critical in order to focus on early detection and enhance cancer treatment strategies. In Ethiopia, however, there is a scarcity of information. As a result, the aim of this study was to determine the pooled estimated prevalence of quality of life among cancer patients in Ethiopia.

MATERIALS AND METHODS

This systematic review and meta-analysis were searched through MEDLINE, Pub Med, Cochrane Library, and Google Scholar by using different search terms on the prevalence of health-related quality of life of cancer patients and Ethiopia. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument was used for critical appraisal of studies. The analysis was done using STATA 14 software. The Cochran Q test and I2 test statistics were used to test the heterogeneity of studies. The funnel plot and Egger's test were used to show the publication bias. The pooled prevalence of health-related quality of life of cancer with a 95% confidence interval was presented using forest plots.

RESULTS

A total of 12 studies with 3, 479 participants were included in this review and the overall pooled estimates mean score of health-related quality of life among cancer patients in Ethiopia was 57.91(44.55, 71.27, I2 = 98.8%, p≤0.001). Average monthly income (AOR:3.70;95%CI:1.31,6.10), Stage of cancer (AOR:4.92;95% CI:2.96,6.87), Physical functioning(AOR:4.11;95%CI:1.53,6.69), Social functioning(AOR:3.91;95% CI:1.68,6.14) were significantly associated with quality of life. Subgroup meta-analysis of health-related quality of life of cancer patients in Ethiopia done by region showed that a higher in Addis Ababa 83.64(78.69, 88.60), and lower in SNNP region16.22 (11.73, 20.71), and subgroup analysis done based on the type of cancer showed that higher prevalence of health-related quality of life among cancer patients was breast cancer 83.64(78.69, 88.60).

CONCLUSION

This review showed that the overall health related quality of life was above an average. Furthermore, average monthly income, cancer stage, physical, and social functioning were all significant determinants in cancer patients' QOL.as a result, this review suggests that quality of life evaluation be incorporated into a patient's treatment routine, with a focus on linked components and domains, as it is a critical tool for avoiding and combating the effects of cancer and considerably improving overall health. In general, more research is needed to discover crucial determining elements utilizing more robust study designs.

DM management in HIV patients: the adoption of population health management to transform the chronic management of HIV

BACKGROUND

The success of antiretroviral therapies has made human immunodeficiency virus (HIV) a chronic disease, changing the care scenario dramatically. This study aimed to measure adherence to diabetes mellitus standards of care provided for people living with HIV (PLWH). Diabetes represents a paradigmatic case for tackling chronic care management in this target group.

METHODS

This retrospective observational study was performed on administrative health data retrieved from 2014 to 2016, with a validated algorithm to identify patients with HIV using: (i) hospital discharge records (ICD9-CM codes); (ii) drug dispensing records (with ATC codes); and (iii) disease-specific exemptions from co-payments for healthcare services. HIV-related treatments, comorbidities and health service utilization were measured, as was adherence to clinical guidelines-recommended standards of care for diabetes.

RESULTS

A population of 738 cases were identified in two Local Health Authorities in Italy, representing a prevalence of 0.14% of the general population, in line with the expected prevalence. Thirty-one cases of HIV patients diagnosed with diabetes were identified, a prevalence ratio of 4.2% compared to the 8% in the overall population. Adherence to diabetes standards of care tested within the same population was low, with the exception of those tests commonly administered for standard HIV follow-up care.

CONCLUSIONS

The use of administrative data, combined with a Population Health Management approach represents a powerful tool for evaluating system capacity to manage HIV comorbidities. Study findings prove that it is time to design new care models for PLWH, affected by one or more chronic conditions, both to prevent their onset and to manage their comorbidities.

Higher intensive care unit consultations for COVID-19 patients living with HIV compared to those without HIV coinfection in Uganda

Coronavirus disease-2019 (COVID-19) is the leading cause of death worldwide from a single infectious agent. Whether or not HIV infection affects clinical outcomes in patients with COVID-19 remains inconclusive. This study aimed to compare the clinical outcomes of people living with HIV (PLWH) and non-HIV-infected patients hospitalized during the second wave of the COVID-19 pandemic in Uganda. We retrospectively retrieved data on patients with COVID-19 who were admitted to the Mulago National Referral Hospital in Uganda between April 2021 and mid-July 2021. We performed propensity-score-matching of 1:5 to compare outcomes in COVID-19 patients living with and those without HIV coinfection (controls). We included 31 PLWH and 155 non-HIV controls. The baseline characteristics were similar across groups (all p values > 0.05). PLWH had close to threefold higher odds of having ICU consultation compared to controls (odds ratio [OR]: 2.9, 95% CI: 1.2-6.9, p = 0.015). There was a trend toward having a severe or critical COVID-19 illness among PLWHIH compared to controls (OR: 1.9, 95% CI: 0.8-4.7, p = 0.164). Length of hospitalization was not significantly different between PLWH and non-HIV controls (6 days vs. 7 days, p = 0.184). Seven-day survival was 63% (95% CI: 42%-78%) among PLWH and 72% (95% CI: 61%-82%) among controls while 14-day survival was 50% (95% CI: 28%-69%) among PLWH and 65% (95% CI: 55%-73%) among controls (p = 0.280). There was another trend toward having 1.7-fold higher odds of mortality among PLWH compared to controls (OR: 1.7, 95% CI: 0.8-3.8, p = 0.181). Our data suggest that PLWH may be at an increased risk of severe or critical COVID-19 illness requiring ICU consultation. Further studies with larger sample sizes are recommended.

Risk of mortality in HIV-infected COVID-19 patients: A systematic review and meta-analysis

BACKGROUND

The relationship between HIV infection and COVID-19 clinical outcomes remains a significant public health research problem. We aimed to determine the association of HIV comorbidity with COVID-19 mortality.

METHODS

We searched PubMed, Google Scholar and World Health Organization library databases for relevant studies. All searches were conducted from 1st to 7th December 2021. Title, abstract and full text screening was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The relative risk of mortality in HIV-infected COVID-19 patients was computed using a random-effects model. All analyses were performed using Meta and Metasens statistical packages available in R version 4.2.1 software package. The quality of included studies was assessed using the GRADE approach, Egger's test was employed to determine the risk of bias.

RESULTS

A total of 16 studies were included in this review. Among the COVID-19 patients with HIV infection, the mortality rate due to COVID-19 was 7.97% (4 287/53,801), and among the COVID-19 patients without HIV infection, the mortality rate due to COVID-19 was 0.69% (127, 961/18, 513, 747). In the random effects model, we found no statistically significant relative risk of mortality in HIV-infected COVID-19 patients (RR 1.07, 95% CI 0.86-1.32). The between-studies heterogeneity was substantial (I2 = 91%, P < 0.01), while the risk of publication bias was not significant.

CONCLUSION

Findings did not link HIV infection with an increased risk of COVID-19 mortality. Our results add to the conflicting data on the relationship between COVID-19 and HIV infection.

Deprenyl reduces inflammation during acute SIV infection

In the era of antiretroviral therapy, inflammation is a central factor in numerous HIV-associated comorbidities, such as cardiovascular disease, cognitive impairment, and neuropsychiatric disorders. This highlights the value of developing therapeutics that both reduce HIV-associated inflammation and treat associated comorbidities. Previous research on monoamine oxidase inhibitors (MAOIs) suggests this class of drugs has anti-inflammatory properties in addition to neuropsychiatric effects. Therefore, we examined the impact of deprenyl, an MAOI, on SIV-associated inflammation during acute SIV infection using the rhesus macaque model of HIV infection. Our results show deprenyl decreased both peripheral and CNS inflammation but had no effect on viral load in either the periphery or CNS. These data show that the MAOI deprenyl may have broad anti-inflammatory effects when given during the acute stage of SIV infection, suggesting more research into the anti-inflammatory effects of this drug could result in a beneficial adjuvant for antiretroviral therapy.

Anti-HIV Drugs Cause Mitochondrial Dysfunction in Monocyte-Derived Macrophages

Combination antiretroviral therapy (cART) dramatically changed the face of the HIV/AIDS pandemic, making it one of the most prominent medical breakthroughs of the past 3 decades. However, as the life span of persons living with HIV (PLWH) continues to approach that of the general population, the same cannot be said regarding their quality of life. PLWH are affected by comorbid conditions such as high blood pressure, diabetes, and neurocognitive impairment at a higher rate and increased severity than their age-matched counterparts. PLWH also have higher levels of inflammation, the drivers of which are not entirely clear. As cART treatment is lifelong, we assessed here the effects of cART, independent of HIV, on primary human monocyte-derived macrophages (MDMs). MDMs were unskewed or skewed to an alternative phenotype and treated with Atripla or Triumeq, two first-line cART treatments. We report that Triumeq skewed alternative MDMs toward an inflammatory nonsenescent phenotype. Both Atripla and Triumeq caused mitochondrial dysfunction, specifically efavirenz and abacavir. Additionally, transcriptome sequencing (RNA-seq) demonstrated that both Atripla and Triumeq caused differential regulation of genes involved in immune regulation and cell cycle and DNA repair. Collectively, our data demonstrate that cART, independent of HIV, alters the MDM phenotype. This suggests that cART may contribute to cell dysregulation in PLWH that subsequently results in increased susceptibility to comorbidities.

Comorbid diseases and conditions in people with HIV in the UK

OBJECTIVES

This study aimed to characterize the risk of people living with HIV (PLHIV) in the UK progressing to pre-specified HIV-associated comorbidities, compared with matched, HIV-negative controls.

METHODS

Primary and secondary care records from the Clinical Practice Research Datalink (CPRD) and linked Hospital Episode Statistics (HES) were used to identify PLHIV, and a matched cohort from the HIV-negative population. Kaplan Meier curves and Cox proportional hazard models were used to evaluate the risk of developing comorbidities including central nervous system (CNS) disorders, end-stage renal disease, osteoporosis, diabetes, cardiovascular disease (CVD), hypertension, stroke and cancer.

RESULTS

A total of 2945 PLHIV were matched to a cohort of 5890 HIV-negative controls. PLHIV demonstrated an increased hazard ratio (HR) for time to development of incident sleep disorders, depression, osteoporosis, stroke, cancer and renal disease when compared with their matched HIV-negative control. The HRs for anxiety, hypertension, diabetes and CVD were not significantly increased.

CONCLUSIONS

PLHIV in the UK were at a higher risk of developing a number of comorbid conditions, highlighting the need for regular attendance of health reviews such as the annual health reviews recommended by the British HIV Associations (BHIVA) quality standard for care, which are currently not uniformly conducted.

Chemotherapy-induced neutropenia among breast Cancer patients in a tertiary care hospital: Risk and consequences

STUDY OBJECTIVE

To identify the risk factors that may predispose breast cancer patients to Chemotherapy-induced neutropenia (CIN) and its associated complications for the years 2018 and 2020. CIN is an established complication of breast cancer treatment. Clinical Pharmacists can play an important role in the treatment of CIN through involvement in risk assessment to identify patients for oral antimicrobial therapy, drug therapy monitoring, and development of suitable guidelines or policies.

METHODOLOGY

A retrospective study was performed by collecting data of 72 breast cancer patients for the last two years from department of Medical Oncology in a tertiary care hospital.

RESULTS

The overall occurrence of CIN was 59.7% in our study population. Out of 72 patients studied, 43 patients were found to be neutropenic. Using Pearson Chi square test, chemotherapy-induced neutropenia was associated with older age (over 60 y) (p < 0.038), diabetes mellitus (p < 0.050), tumour stage IIIa (p < 0.024), AC (p < 0.051) and taxane chemotherapy regimens (p < 0.041). Febrile neutropenia occurred in 37.28% of patients and the incidence of infection-related mortality [severe septicaemia] was 3.38%.

CONCLUSION

The incorporation of clinical pharmacist must be brought into practice in our country for providing proper guidance to the patient on CIN and its complications. By identifying risk factors for neutropenia, the safe management of CIN may be possible in patients with breast cancer.

Are There Global Syndemics?

In this article, we address the nature of syndemics and whether, as some have asserted, these epidemiological phenomena are global configurations. Our argument that syndemics are not global rests on recognition that they are composed of social/environment contexts, disease clusters, demographics, and biologies that vary across locations. These points are illustrated with the cases of syndemics involving COVID-19, diabetes mellitus, and HIV/AIDS. We draw on theoretical discourse from epidemiology, biology, and anthropology to present what we believe is a more accurate framework for thinking about syndemics with shared elements.

Investigation of the Interaction between Hearing Function and Comorbidities in Adults Living with Human Immunodeficiency Virus

Adults living with the human immunodeficiency virus (HIV) have a high prevalence of co-existing comorbidities. While research indicates that adults living with HIV are at risk of developing hearing impairment, limited research exists on the interaction between hearing function and comorbidities in this population. The objective of this study was to determine and compare the hearing function of a group of adults living with HIV and comorbidities and those without comorbidities. A sample of 132 adults living with HIV underwent a basic audiological test battery to assess their hearing function. Participants with comorbidities were 1.23 times more likely to develop hearing loss, with crude odds of 1.236 (95%CI 0.5467 to 2.795), while those with three comorbidities were 2.52 times more likely to develop hearing loss. Participants with hypertension were 93% more likely to develop hearing loss when compared to nonhypertensive participants (OR = 1.928; 95%CI: 0.7856 to 4.7345). There was only a marginal association between hypercholesterolemia and sensorineural hearing loss (SNHL), with no association between other comorbidities and the type of hearing loss. The current findings raise a need for prioritizing patients with comorbidities in audiological assessment and monitoring in resource-constrained contexts, where capacity versus demand challenges might prevent the provision of audiological services to all adults living with HIV. These findings also highlight the importance of preventive care in this population with regard to the burden of the disease, as it may lead to worse ear and hearing outcomes for affected individuals.

A Mixed Methods, Observational Investigation of Physical Activity, Exercise, and Diet Among Older Ugandans Living With and Without Chronic HIV Infection

ABSTRACT

People living with HIV (PLWH) are at increased risk for cardiovascular disease. Physical activity, exercise, and controlled diet can mitigate this risk, yet these behaviors are understudied in sub-Saharan Africa. Our objective was to describe and compare the meaning, value, and patterns of physical activity, exercise, and diet among PLWH and older adults without HIV in Uganda. This mixed methods, observational study included 30 adult PLWH and 29 adults without HIV who (a) wore an accelerometer to measure physical activity; (b) had weight, height, and waist and hip circumference measured; (c) completed physical fitness measures; and (d) used digital cameras to record photographs and videos of their typical diet and physical activities. Participants were approximately 58 years old and 68% female. Approximately 20% of PLWH and 40% of adults without HIV met physical activity guidelines (p > .05). Qualitative themes included engaging in a variety of exercise, structural barriers to exercising, and typical meals. Older adults in Uganda have low levels of physical activity and homogenous diets, increasing their risk for cardiovascular disease.

Alcohol-Induced Lysosomal Damage and Suppression of Lysosome Biogenesis Contribute to Hepatotoxicity in HIV-Exposed Liver Cells

Although the causes of hepatotoxicity among alcohol-abusing HIV patients are multifactorial, alcohol remains the least explored "second hit" for HIV-related hepatotoxicity. Here, we investigated whether metabolically derived acetaldehyde impairs lysosomes to enhance HIV-induced hepatotoxicity. We exposed Cytochrome P450 2E1 (CYP2E1)-expressing Huh 7.5 (also known as RLW) cells to an acetaldehyde-generating system (AGS) for 24 h. We then infected (or not) the cells with HIV-1ADA then exposed them again to AGS for another 48 h. Lysosome damage was assessed by galectin 3/LAMP1 co-localization and cathepsin leakage. Expression of lysosome biogenesis-transcription factor, TFEB, was measured by its protein levels and by in situ immunofluorescence. Exposure of cells to both AGS + HIV caused the greatest amount of lysosome leakage and its impaired lysosomal biogenesis, leading to intrinsic apoptosis. Furthermore, the movement of TFEB from cytosol to the nucleus via microtubules was impaired by AGS exposure. The latter impairment appeared to occur by acetylation of α-tubulin. Moreover, ZKSCAN3, a repressor of lysosome gene activation by TFEB, was amplified by AGS. Both these changes contributed to AGS-elicited disruption of lysosome biogenesis. Our findings indicate that metabolically generated acetaldehyde damages lysosomes and likely prevents their repair and restoration, thereby exacerbating HIV-induced hepatotoxicity.

Prevalence of diabetes mellitus and hypertension amongst the HIV-positive population at a district hospital in eThekwini, South Africa

Background

Life expectancies of HIV-positive patients have been increasing with the rapid implementation of antiretroviral therapy (ART). This has led to an increase in comorbidities such as diabetes mellitus (DM) and hypertension (HT) amongst the HIV population. The burden of the non-communicable diseases (NCDs) such as DM and HT need to be quantified in order to ensure that patients receive optimal integrated care as patients often access care at different clinics compromising holistic care.

Aim

The aim of the study was to determine the prevalence of DM and HT amongst the HIV-positive population.

Setting

The study was conducted at Wentworth Hospital, a district facility in South Durban, KwaZulu-Natal.

Methods

This cross-sectional study was undertaken to determine the prevalence of two NCDs, namely DM and HT in HIV-positive patients attending the ART clinic at a district hospital in the eThekwini district. We compared the socio-demographic and clinical profiles of those with and without comorbidities. A sample of 301 HIV-positive patients were administered a structured questionnaire.

Results

Of the 301 patients, 230 (76.41%) had HIV only (95% confidence interval [CI]: 71.25–80.89) and 71 (23.59%) had HIV and at least one comorbidity, namely DM and/or HT (95% CI: 19.11-28.75). Hypertension was the most prevalent comorbidity. This study revealed that there was no association between the duration of ART and comorbidities. Older age and body mass index (BMI) were associated with comorbidities, whilst gender and ethnicity were not associated.

Conclusion

Non-communicable diseases such as DM and HT do pose a burden for HIV-positive patients attending the ARV clinic at this district facility. This study highlights the definite need to plan for the increased burden of NCDs as HIV-positive patients live longer and gain weight.

Higher comorbidity burden predicts worsening neurocognitive trajectories in people with HIV

BACKGROUND

Age-related comorbidities accumulate faster in people with HIV (PWH) than in those without (PWoH). We evaluated whether a validated multimorbidity scale, the Charlson Index, predicted neurocognitive trajectories in PWH.

METHODS

Scaled scores a comprehensive neuropsychological battery were averaged across all visits. Multilevel modeling examined between- and within-person predictors of global neurocognition. At the between-person level, averaged Charlson scores were examined as a predictor of neurocognitive change rate, covarying for HIV disease characteristics. Within-persons, visit-specific Charlson Index was used to predict fluctuations in global neurocognition at the same and next visit, covarying for disease measures.

RESULTS

Participants were 1195 PWH (mean baseline age 43·0; SD 9·7 years) followed for a mean of 7·1 years (range 0·5-20·5). At the between-person level, more rapid neurocognitive worsening correlated with higher (worse) average Charlson scores (standardized β -0·062, SE 0·015; p=0·001) and lower CD4 nadir (standardized β 0·055, SE 0·021; p=0·011), but not viral suppression or average CD4+ lymphocytes (ps > 0·05). At the within-person level, poorer visit-specific neurocognition was related to worse concurrent, but not preceding, Charlson scores (standardized β-0·046, SE 0·015; p = 0·003), detectable HIV viral load (standardized β0·018, SE 0·006; p = 0·001) and higher CD4+ (standardized β0·043, SE 0·009; p < 0·001).

CONCLUSION

The impact of comorbidities on neurocognitive decline exceeded that of HIV disease factors. Although correlative, the temporal relationships suggested that treatment of comorbidities might improve neurocognitive prognosis for PWH.

Statistical models for analyzing count data: predictors of length of stay among HIV patients in Portugal using a multilevel model

BACKGROUND

This study offers a comprehensive approach to precisely analyze the complexly distributed length of stay among HIV admissions in Portugal.

OBJECTIVE

To provide an illustration of statistical techniques for analysing count data using longitudinal predictors of length of stay among HIV hospitalizations in Portugal.

METHOD

Registered discharges in the Portuguese National Health Service (NHS) facilities Between January 2009 and December 2017, a total of 26,505 classified under Major Diagnostic Category (MDC) created for patients with HIV infection, with HIV/AIDS as a main or secondary cause of admission, were used to predict length of stay among HIV hospitalizations in Portugal. Several strategies were applied to select the best count fit model that includes the Poisson regression model, zero-inflated Poisson, the negative binomial regression model, and zero-inflated negative binomial regression model. A random hospital effects term has been incorporated into the negative binomial model to examine the dependence between observations within the same hospital. A multivariable analysis has been performed to assess the effect of covariates on length of stay.

RESULTS

The median length of stay in our study was 11 days (interquartile range: 6-22). Statistical comparisons among the count models revealed that the random-effects negative binomial models provided the best fit with observed data. Admissions among males or admissions associated with TB infection, pneumocystis, cytomegalovirus, candidiasis, toxoplasmosis, or mycobacterium disease exhibit a highly significant increase in length of stay. Perfect trends were observed in which a higher number of diagnoses or procedures lead to significantly higher length of stay. The random-effects term included in our model and refers to unexplained factors specific to each hospital revealed obvious differences in quality among the hospitals included in our study.

CONCLUSIONS

This study provides a comprehensive approach to address unique problems associated with the prediction of length of stay among HIV patients in Portugal.

Effect of the Test and Treat Strategy on Mortality Among HIV-Positive Adult Clients on Antiretroviral Treatment in Public Hospitals of Addis Ababa, Ethiopia

Background

The primary goal of antiretroviral therapy is to prevent human immune deficiency virus (HIV)-related morbidity and mortality. Deferring antiretroviral therapy (ART) until CD4 counts decline puts individuals with HIV at risk of HIV-related morbidity and mortality.

Objective

This study aims to assess the effect of the test and treat strategy on mortality among HIV-positive clients on ART in public hospitals in Addis Ababa.

Methods

A retrospective cohort study was conducted at five selected public hospitals in Addis Ababa. A cohort of 216 ART clients taken as an exposed group (test and treat" strategy) from 2017 to 2019 and 216 ART clients as an unexposed group taken from 2014 to 2017; totally, 432 clients were included in the study. Multivariate Cox regression was used to estimate the effect of the test and treat strategy on the survival of ART clients adjusting for other covariates.

Results

The 432 clients contributed to a total of 1025.17 person-years follow-up. Ninety-one (21.06%) of them died, 14.3% were unexposed and 6.7% were exposed (test and treat). The incidence of death was 92.4 and 81.8/1000 person-years in the unexposed group and exposed group, respectively, with an overall mortality rate of 88.8/1000 person-years. Besides, test and treat strategy (AHR: 0.31; 95% CI: 0.19, 0.52), baseline CD4 counts >350 cells/mm3 (AHR 0.40; 95%: CI: 0.20, 0.80), bedridden functional status (AHR 2.46; 95% CI: 1.41, 4.27), poor adherence (AHR 3.25; 95% CI: 1.410-7.51), moderate malnutrition on last visit (AHR 2.56; 95% CI: 1.30-5.04) and staying on original regimen (AHR 4.68; 95% CI 2.72, 8.07) were independent predictors of mortality.

Conclusion

Mortality among HIV patients on treatment decreased significantly since the start of the test and treat strategy. Therefore, test and treat strategy should be strengthened in all public and private facilities throughout the country.

CD4/CD8 ratio, comorbidities, and aging in treated HIV infected individuals on viral suppression

The progression of the human immunodeficiency virus (HIV) infection to acquired immunodeficiency syndrome (AIDS) can be efficiently interrupted by antiretroviral therapy (ART). However, even successfully treated HIV-infected individuals are prone to develop non-AIDS-related diseases that affect the metabolism and several organs and systems. Biomarkers that predict the occurrence of comorbidities may help develop preventive measures. Current research shows that CD4+ T cell counts and viral load do not predict the development of non-AIDS-related diseases. The CD4/CD8 ratio has been indicated as a suitable marker of persistent immune dysfunction and the occurrence of non-AIDS-related events in treated HIV-positive patients. In this study, we explored the relationship between CD4/CD8 ratios, comorbidities, and aging in ART-treated HIV patients on viral suppression. We collected and evaluated data from 352 HIV-positive adults who were virologically suppressed (<40 copies/mL) on ART and with CD4 counts above 350 cells/mm3 . The median age for participants was 46 years, 218 individuals had at least one comorbidity, and 239 had inverted CD4/CD8 ratios (<1). Current CD4/CD8 ratios were predicted by baseline CD4/CD8 ratios and nadir CD4 counts. Despite the high rates of inverted CD4/CD8 ratios and prevalence of comorbidities, no association between them was observed. The prevalence of comorbidities was significantly higher in older individuals, though aging alone did not explain the rate of all individual comorbidities. Low CD4/CD8 ratios were linked to neurocognitive disorders, suggesting that persistent T cell dysfunction contributes to neurocognitive decline.

Prevalence, healthcare costs and management of non-communicable diseases in people living with human immunodeficiency virus: A scoping review

BACKGROUND

Coexistence of human immunodeficiency virus (HIV) and non-communicable diseases (NCDs) is an important public health issue of increasing concern. However, the prevalence, healthcare costs and management protocols for NCDs in people living with HIV (PLHIV) remain unclear in most settings.

AIM

To scope evidence on prevalence, healthcare costs and disease management protocols associated with NCDs in PLHIV from studies published before July 2019.

METHODS

Electronic databases were searched for published articles, and reference lists were checked for relevant studies. Key terms included were HIV/AIDS, co-morbidity or multi-morbidity, NCDs, healthcare costs, treatment protocols, diabetes mellitus, hypertension in various combinations.

RESULTS

A total of 152 records were assessed, and thereafter 25 studies were included in the final review after all the elimination. Twelve of the 25 studies mostly reported prevalence of NCDs in PLHIV, 4 reported impact of HIV-NCD co-morbidity on healthcare costs and 1 reported management protocols and capacity of antiretroviral therapy (ART) sites to manage HIV-NCD co-morbidity.

CONCLUSIONS

Results showed higher prevalence rates of diabetes mellitus and hypertension in PLHIV compared with HIV-negative people. However, there was inconsistency in NCD prevalence data from studies conducted in sub-Saharan African (SSA) countries, and limited research evidence on capacity of ART sites to manage NCDs in PLHIV. Low prevalence rates of NCDs reported in SSA countries could be an indication of limited capacity to screen for NCDs because of the influence of health system and/or patient-level factors. Most studies were generally limited to cross-sectional studies, with very few interventional, longitudinal studies.

The prevalence of comorbidities among adult people diagnosed with HIV infection in a tertiary care hospital in western Saudi Arabia

BACKGROUND

The life expectancy of people living with HIV is markedly increasing with the introduction of effective antiretroviral medications. However, these patients face an increased risk of developing multi-morbidities-especially with advanced age. This study was conducted to assess the prevalence of and risk factors associated with the occurrence of chronic comorbidities among patients diagnosed with HIV infection.

METHODS

A retrospective chart review was conducted on the medical records of patients with HIV diagnoses from 2000 to 2018. Data were collected on age, sex, date of diagnosis, associated co-morbidities, antiretroviral medications (ART) and status at time of data collection (alive or deceased). Only adult patients 18 years or above were studied.

RESULTS

A total of 130 confirmed HIV cases were included. Patient ages ranged from 23 to 86 years old (mean±SD 50.1±12.6). Almost half of the patients (48.5%) had at least one associated comorbidity. The most common chronic comorbidity was diabetes mellitus (15.4%), followed by dyslipidemia (10.8%), hypertension (10.8%) and lymphoma (10.0%). Comorbidity proportions increased with advanced patient age (p=0.047). Three or more comorbidities were reported in 40.7% of patients aged 60 years old or above. Using logistic regression analysis, only patients aged 50 years old or above were more likely to have at least one comorbidity (OR=7.59, 95%CI=2.25, 25.61).

CONCLUSIONS

The burden of chronic comorbidities among people diagnosed with HIV is high, especially among older age individuals, with an increasing number of comorbidities per patient. Proper counseling for HIV patients is highly recommended-not only for prevention of other infectious diseases (e.g., vaccination) but also for lifestyle modification and self-management for those with chronic conditions.

Prevalence of diabetes mellitus and hypertension in people living with human immunodeficiency virus on antiretroviral therapy in Gweru district, Zimbabwe

Background

While antiretroviral therapy (ART) has markedly increased survival in people living with human immunodeficiency virus (PLHIV), emerging trends of co-existence of non-communicable diseases (NCDs) and HIV could negate the gains already achieved in controlling HIV.

Aim

The study aimed to determine the prevalence of hypertension and diabetes mellitus in PLHIV on ART in Gweru district.

Setting

Six high-volume ART sites in Gweru district under Midlands province in Zimbabwe.

Methods

This was a cross-sectional study. Screening and data collection occurred over a 3-month cycle when all patients were expected to have visited the ART sites for their monthly ART drug supply. The process also allowed the identification of health system challenges regarding data management for HIV-NCD comorbidity. Poisson regression analysis was used to calculate NCD prevalence ratio (PR) in PLHIV.

Results

Nearly 18 000 PLHIV registered for ART were identified. Hypertension (19.5%) and diabetes mellitus (8.4%) were the most common NCDs identified with a high proportion of those who did not know their diagnosis (over 50%). The prevalence of hypertension and/or diabetes mellitus among women was 74.9% compared to 25.1% in men (PR 3.22; 95% CI: 3.07–5.51, p = 0.0000). Other factors associated with increased prevalence of hypertension and/or diabetes mellitus were age group of ≥ 60 years (PR 2.5; 95% CI: 1.42–3.22, p = 0.00023), and duration of ≥ 5 years on ART (PR 6.4; 95% CI: 4.70–8.01, p = 0.0011). Separate data collection for NCDs and HIV was a key challenge affecting quantification of magnitude of HIV-NCDs comorbidity and subsequently management of NCDs in PLHIV.

Conclusions

Indications of increasing prevalence of NCDs in PLHIV call for integrated electronic data management for HIV, TB and NCDs. This will allow active NCD case finding, and eventually improve prevalence data and treatment for HIV-NCD comorbidity. Future studies should focus on the health experiences and access to treatment in PLHIV diagnosed with NCDs; and to establish the accurate manner in which HIV status, ART and NCDs might be associated, through conducting a case control or cohort study.

Polypharmacy and potential drug-drug interactions for people with HIV in the UK from the Climate-HIV database

Objectives

People with HIV (PWHIV) are likely to need therapies for comorbidities as they age. We assessed risk of drug–drug interactions (DDIs) in PWHIV.

Methods

The Climate‐HIV electronic recording system was used to cross‐sectionally analyse records from PWHIV aged ≥ 18 years attending four UK HIV units with a current antiretroviral (ARV) prescription in February 2018. Antiretroviral and non‐ARV medications were categorized by clinical significance of DDIs (University of Liverpool DDI tool). Potential DDIs were predicted using treatment guidelines for commonly recorded comorbidities.

Results

Among 4630 PWHIV (44% female), 41% were ≥ 50 years old. The average number of non‐ARV comedications increased from < 1 for patients aged ≤ 24 years to > 5 for patients aged ≥ 75 years; 65% were taking one or more non‐ARV comedications. The median (interquartile range) number of non‐ARVs was 1 (0–2) and 2 (1–5) for those aged < 50 and ≥ 50 years, respectively. Common comorbidities/concurrent health conditions occurred more frequently in patients aged ≥ 50 years vs. < 50 (53% vs. 34%). Boosted protease inhibitors were associated with the highest proportion of contraindicated comedications; dolutegravir and raltegravir had the fewest. For non‐ARVs, sildenafil and quetiapine were most likely to result in DDIs. Guideline‐recommended treatments for hepatitis C, hepatitis B, and tuberculosis had the highest proportions of contraindications when combined with ARV regimens, while treatments for hepatitis C, malignancy, and mental health conditions had the highest proportion of combinations potentially causing DDIs requiring dose monitoring or adjustment.

Conclusions

Non‐ARV use by PWHIV is high and increases with age. Treatment decisions for ageing PWHIV should consider guideline recommendations for comorbidities.

Higher Proportion of Abnormal Nutritional Status Among Well-Suppressed HIV-Infected Elderly Asians Compared to HIV-Negative Individuals

Older adults face physiological, psychological, social, and economic changes, which may impair nutritional status, making the body vulnerable to illness and adverse clinical outcomes. Little is known regarding the nutritional status among elderly people living with HIV (PLHIV). We aimed to study the prevalence of malnutrition and the associated factors in a Thai aging cohort. A cross-sectional study was conducted among PLHIV >50 years of age on long-term antiretroviral therapy and HIV-negative controls, frequency matched by sex and age in Bangkok, Thailand. Nutritional status was assessed by the Mini Nutrition Assessment (MNA) tool. Abnormal nutritional status was defined as MNA score <24 (malnutrition and at risk of malnutrition). Body composition was measured by bioelectrical impedance analysis using Body Composition Analyzer. Demographic and disease-related factors were assessed for their association with abnormal nutrition status using multivariable logistic regression. There were 349 PLHIV and 103 HIV-uninfected controls, with median age 55 years. The majority were male (63%) with median body mass index (BMI) of 23.4 kg/m². PLHIV had lower BMI [median, 23.1 (IQR, 20.8-25.2) vs. 25.3 (22.3-28.7) kg/m², p < .001], lower fat percent [22.8% vs. 26.3%, p < .001] and lower fat mass [14.2 vs. 16.9 kg, p < .001] and higher abnormal nutritional status (18.05% vs. 6.8%, p = .005) than controls. In the multivariate model, older age (adjusted odds ratio [aOR], 1.06, 95% confident interval [CI]: 1.01-1.12, p = .03), positive HIV status (aOR, 2.67, 95% CI: 1.07-6.65, p = .036), diabetes mellitus (aOR, 2.21, 95% CI: 1.003-4.87, p = .049), lower fat mass (aOR, 0.70, 95%CI: 0.57-0.86, p < .001), and lower BMI (aOR, 0.63, 95% CI: 0.51-0.78, p < .001) were independently associated with abnormal nutritional status. PLHIV had higher risks for abnormal nutritional status compared with HIV-uninfected individuals. Regular screening and monitoring of nutritional status among PLHIV may promote better health outcomes.

Bioenergetic adaptations to HIV infection. Could modulation of energy substrate utilization improve brain health in people living with HIV-1?

The human brain consumes more energy than any other organ in the body and it relies on an uninterrupted supply of energy in the form of adenosine triphosphate (ATP) to maintain normal cognitive function. This constant supply of energy is made available through an interdependent system of metabolic pathways in neurons, glia and endothelial cells that each have specialized roles in the delivery and metabolism of multiple energetic substrates. Perturbations in brain energy metabolism is associated with a number of different neurodegenerative conditions including impairments in cognition associated with infection by the Human Immunodeficiency Type 1 Virus (HIV-1). Adaptive changes in brain energy metabolism are apparent early following infection, do not fully normalize with the initiation of antiretroviral therapy (ART), and often worsen with length of infection and duration of anti-retroviral therapeutic use. There is now a considerable amount of cumulative evidence that suggests mild forms of cognitive impairments in people living with HIV-1 (PLWH) may be reversible and are associated with specific modifications in brain energy metabolism. In this review we discuss brain energy metabolism with an emphasis on adaptations that occur in response to HIV-1 infection. The potential for interventions that target brain energy metabolism to preserve or restore cognition in PLWH are also discussed.

Health Literacy Among In-Care Older HIV Diagnosed Persons with Multimorbidity: MMP NYS (Excluding NYC)

Older persons living with diagnosed HIV (PLWDH) are also at risk for age-related chronic conditions. With conflicting results on studies assessing health literacy and durable viral suppression, this study is the first in assessing this relationship using representative data on older in-care HIV-diagnosed persons with multimorbidity. Weighted data collected 2009-2014 from the Medical Monitoring Project (MMP) was used. Health literacy was assessed using the three-item Brief Health Literacy Screen (BHLS). The mean health literacy score was 11.22 (95% CI 10.86-11.59), and the mean multimorbidity was 4.75 (SE = 0.32). After adjusting, health literacy (OR 0.87, 95% CI 0.77-0.99) was found to be significantly associated with durable viral suppression. Adequate health literacy can help with achieving durable viral suppression. For these persons, addressing health literacy might increase their ability to access and navigate the healthcare system, thereby helping them stay engaged and maintain adherence to HIV care.

The HIV-Tat protein interacts with Sp3 transcription factor and inhibits its binding to a distal site of the sod2 promoter in human pulmonary artery endothelial cells

Redox imbalance results in damage to cellular macromolecules and interferes with signaling pathways, leading to an inflammatory cellular and tissue environment. As such, the cellular oxidative environment is tightly regulated by several redox-modulating pathways. Many viruses have evolved intricate mechanisms to manipulate these pathways for their benefit, including HIV-1, which requires a pro-oxidant cellular environment for optimal replication. One such virulence factor responsible for modulating the redox environment is the HIV Transactivator of transcription (Tat). Tat is of particular interest as it is actively secreted by infected cells and internalized by uninfected bystander cells where it can elicit pro-oxidant effects resulting in inflammation and damage. Previously, we demonstrated that Tat regulates basal expression of Superoxide Dismutase 2 (sod2) by altering the binding of the Sp-transcription factors at regions relatively near (approx. -210 nucleotides) upstream of the transcriptional start site. Now, using in silico analysis and a series of sod2 promoter reporter constructs, we have identified putative clusters of Sp-binding sites located further upstream of the proximal sod2 promoter, between nucleotides -3400 to -210, and tested their effect on basal transcription and for their sensitivity to HIV-1 Tat. In this report, we demonstrate that under basal conditions, maximal transcription requires a cluster of Sp-binding sites in the -584 nucleotide region, which is extremely sensitive to Tat. Using chromatin immunoprecipitation (ChIP) we demonstrate that Tat results in altered occupancy of Sp1 and Sp3 at this distal Tat-sensitive regulatory element and strongly stimulated endogenous expression of SOD2 in human pulmonary artery endothelial cells (HPAEC). We also report altered expression of Sp1 and Sp3 in Tat-expressing HPAEC as well as in the lungs of HIV-1 infected humanized mice. Lastly, Tat co-immunoprecipitated with endogenous Sp3 but not Sp1 and did not alter the acetylation state of Sp3. Thus, here, we have defined a novel and important cis-acting factor in HIV-1 Tat-mediated regulation of SOD2, demonstrated that modulation of Sp1 and Sp3 activity by Tat promotes SOD2 expression in primary human pulmonary artery endothelial cells and determined that pulmonary levels of Sp3 as well as SOD2 are increased in the lungs of a mouse model of HIV infection.

Chronic Diseases Multimorbidity among Adult People Living with HIV at Hawassa University Comprehensive Specialized Hospital, Southern Ethiopia

Background

Due to the wide implementation of antiretroviral therapy (ART), people living with HIV (PLWHIV) are now living longer. This increased the risk of developing noncommunicable chronic diseases (NCCDs) among them.

Objective

We aimed to describe prevalence of NCCDs multimorbidity among PLWHIV at Hawassa University Comprehensive Specialized Hospital (HUCSH).

Method

In April 2016, institution-based cross-sectional study was conducted among PLWHIV, aged ≥ 18 years at the ART unit of HUCSH. A nurse working in the ART unit interviewed patients and reviewed medical records. Data on the NCCDs and its risk factors were obtained. List of diseases considered in this study were arthritis, diabetes mellitus, hypertension, congestive heart failure (CHF), rheumatic heart diseases (RHD), chronic bronchitis, asthma, and cancer.

Results

More than half of the respondents (196) had at least one of the NCCDs and 34 (8.9%) had multimorbidity. The main system of the body affected were the musculoskeletal system, 146 (38.2%) and respiratory system, 46 (12.0%). There was no significant difference in the prevalence of individual NCCDs by gender. Patients aged above 44 years, patients with ART duration of at least 6 years, and patients with higher CD4 counts had increased odds of having any one of the NCCDs. Multimorbidity patients with a longer ART duration had an increased risk.

Conclusion

The prevalence of NCCD multimorbidity among PLWHIV was high. Monitoring the occurrence of NCCDs among PLWHIV and noncommunicable disease care is recommended.

Differential contribution of chronic binge alcohol and antiretroviral therapy to metabolic dysregulation in SIV-infected male macaques

The incidence of alcohol use disorder (AUD) is higher among people living with HIV (PLWH). The advent and continued development of antiretroviral therapy (ART) has significantly reduced mortality, shifting the course of HIV infection to a chronic illness. However, this is associated with an increased incidence of comorbid conditions, including type 2 diabetes mellitus, insulin resistance, and cardiovascular complications. Using a nonhuman primate model of simian immunodeficiency virus (SIV) infection, previous studies have demonstrated that chronic binge alcohol (CBA) administration decreases whole body insulin responsiveness, irrespective of ART administration. The objective of the current study was to determine the effects of CBA and ART on insulin-sensitive peripheral tissues before the development of overt clinical symptoms of SIV disease. Our results show that CBA reduced omental adipocyte cell size, increased collagen expression, and decreased the in vitro differentiation potential of adipose-derived stem cells. In contrast, it did not alter skeletal muscle or omental or hepatic expression of insulin signaling proteins. However, ART significantly decreased skeletal muscle expression of phosphatase and tensin homolog, total mechanistic target of rapamycin, and ribosomal protein S6. In addition, ART increased hepatic phosphorylation of AMP-activated protein kinase α and increased gene expression of key enzymes required for gluconeogenesis and fatty acid synthesis. These findings suggest that CBA and ART differentially promote adverse metabolic effects in an organ-specific manner that may underlie insulin resistance associated with alcohol, SIV, and ART. Whether this is translated in PLWH with AUD remains to be determined.

CLINICAL PRESENTATION OF HIV-INFECTED PATIENTS IN A PSYCHIATRIC HOSPITAL IN SOUTH AFRICA

BACKGROUND

Africa is profoundly stricken by the HIV pandemic. People living with HIV/AIDS are more likely to be diagnosed with psychiatric disorders than the general population. We describe the prevalence of different mood and psychiatric disorders in HIV/AIDS infected patients with serious mental illness.

MATERIALS AND METHODS

We retrospectively sourced data from 105 patient files, at Weskoppies Hospital, between January 2012 and December 2016.

RESULTS

56 patients had a psychotic disorder; 27 patients had a mood disorder and three patients had a cognitive disorder. Multiple diagnoses were observed in seven patients with a mood and psychotic disorder; ten patients with a psychotic and cognitive disorder and one patient with a mood and cognitive disorder. One patient had all three diagnoses. The most common medical co-morbidities were hypertension (15.24%) and tuberculosis (13.33%).

CONCLUSION

Mentally ill patients who are HIV positive mostly present with mood and psychotic disorders. Clinicians need to be vigilant to detect neuropsychiatric manifestations of HIV infection to effectively manage and optimise treatment. This study highlights the need for further intervention in these vulnerable patients.

Efectividad de un manual de autocuidado para el manejo de síntomas en personas colombianas que viven con VIH

Estudio con resultados del nodo Cali, en colaboración con la Red Internacional de Enfermeras Investigadoras en VIH-Sida. Objetivo: medir la efectividad de un manual de autocuidado para el manejo de síntomas por VIH-Sida, comparando frecuencia de síntomas, calidad de vida, adherencia y utilidad del manual en personas con el virus del Sida que usaron el de autocuidado y las que usaron un manual de nutrición. Materiales y métodos: estudio cuasiexperimental con grupo experimental (manual de autocuidado para el manejo de síntomas) y control (manual de nutrición) con 51 personas; mediciones al inicio y a los dos meses. Resultados: los síntomas al inicio fueron 16, igual para los dos grupos. A los dos meses disminuyeron, la diferencia no fue significativa para la comparación entre grupos; se encontró aumento en el puntaje global de calidad de vida de 51 a 54 en el grupo experimental, y de 54 a 56 en el grupo control; la mayor utilidad fue para el manual de autocuidado con 88%, comparado con el de nutrición, 75%. Se reconoce la importancia de diseñar materiales educativos para responder a las necesidades de las personas que viven con el virus del Sida. Conclusión: el manual de autocuidado fue considerado útil por la mayoría de los participantes del grupo experimental.
