Cancer and the 'other' noncommunicable chronic diseases in older people living with HIV/AIDS in resource-limited settings: a challenge to success

Prevalence of Mental Health Disorders and Their Associated Risk Factors Among People Living with HIV in Rwanda: A Cross-Sectional Study

While life expectancy of people living with HIV is increasing, their burden of non-communicable diseases, including mental health disorders, is growing as well. The aim of this study is to investigate the prevalence and identify the risk factors associated with mental health disorders among this population in Rwanda. This cross-sectional study enrolled people living with HIV from 12 HIV clinics across Rwanda using random sampling. Trained HIV nurses conducted the Mini International Neuropsychiatric Interview to estimate the prevalence of major depressive episode, post-traumatic stress disorder, and generalized anxiety disorder. Sociodemographic, psychosocial, and HIV-related data were also collected. Associated risk factors for being diagnosed with one of the mental health disorders were assessed using modified Poisson regression with robust error variance. Of 428 participants, 70 (16.4%) had at least one mental health disorder with major depressive episode being most prevalent (n = 60, 14.0%). Almost all participants were adherent to antiretroviral therapy (n = 424, 99.1%) and virally suppressed (n = 412, 96.9%). Of those diagnosed with a mental health disorder, only few were aware of (n = 4, 5.7%) or under treatment for this mental health disorder (n = 5, 7.2%). Mental health disorders were associated with experiences of HIV-related stigma and discrimination (aRR = 2.14, 95%CI 1.30-3.53, p = 0.003). The results demonstrate underdiagnosis and undertreatment of mental health disorders among Rwandan People Living with HIV. Using HIV nurses to diagnose mental health disorders could serve as a low-cost strategy for integrating mental health care with existing HIV services and could inspire the implementation in other low-resource settings.

Mapping evidence on barriers to and facilitators of diagnosing noncommunicable diseases among people living with human immunodeficiency virus in low- and middle-income countries in Africa: A scoping review

Objectives

To map the evidence on the barriers to and facilitators of diagnosing noncommunicable diseases among people living with HIV in low- and middle-income countries in Africa.

Introduction

Noncommunicable diseases are increasing among people living with HIV. Thus, strengthened and sustained diagnosis of noncommunicable diseases through integrated noncommunicable diseases and HIV care is needed to improve patient outcomes. However, there is paucity of evidence on the barriers and facilitators diagnosing noncommunicable diseases among people living with HIV in low- and middle-income countries.

Methods

The Arksey and O'Malley methodological framework was used. A comprehensive systematic search of academic databases (MEDLINE, Academic Search Complete, APA PsycInfo, CAB, and Health Source/Nursing) was performed via EBSCO search and PubMed. The articles were reviewed independently by three reviewers. The results were structured using Capability-Opportunity-Motivation-Behavior model and Theoretical Domains Framework.

Results

A total of 152 articles were retrieved for full-text review. Forty-one articles met the inclusion criteria. The identified barriers were relevant to all the Capability-Opportunity-Motivation-Behavior constructs and 14 Theoretical Domains Framework domains. A lack of knowledge and awareness of noncommunicable diseases, fear of stigma, financial problems and out-of-pocket payments were the most cited patient-level barriers. Healthcare providers (knowledge and awareness gaps, skill and competence deficiencies, unwillingness, burnout, low motivation, and apathy) were frequently cited. Lack of equipment, noncommunicable disease medications and supply chain challenges, lack of integrated noncommunicable disease and HIV care, and shortage of trained healthcare providers were identified as health-system-level barriers.

Conclusion

This scoping review is the first to identify barriers and facilitators using a theoretical framework. The most cited barriers include a lack of integrated HIV and noncommunicable disease care, equipment and logistics chain challenges for noncommunicable diseases, patients' and healthcare providers' lack of knowledge and awareness of noncommunicable diseases, and healthcare provider's skill and competency deficiencies. Addressing these issues is crucial for improving patient outcomes and reducing the burden on healthcare providers and health systems.

Higher prevalence of kidney function impairment among older people living with HIV in Uganda

Background

People living with HIV (PLWH) are at risk of kidney function impairment due to HIV-related inflammation, antiretroviral therapy (ART), diabetes mellitus, and hypertension. Older persons may experience a higher burden of chronic kidney disease (CKD) as kidney function declines with increasing age. There is a paucity of data comparing the prevalence of kidney function impairment in older PLWH to that in HIV-uninfected people in sub-Saharan Africa.

Methods

We conducted a cross-sectional study among people aged ≥ 60 years living with and without HIV in Kampala, Uganda who were matched 1:1 by community location. We collected data on sociodemographics, comorbidities, and HIV-related clinical characteristics. We defined kidney function impairment as an estimated glomerular filtration rate(eGFR) < 60mls/min/1.73m2 with or without proteinuria. We constructed multivariable logistic regression models to study associations between participant characteristics and kidney function impairment.

Results

We enrolled 278 people (median age 66 years); 50% were PLWH, and 51.8% were female. Overall, the prevalence of kidney function impairment was 23.0% (95% CI:18.4%-28.4%); 33.1% (95% CI: 25.7%-41.4%) versus 12.9% (95% CI: 8.3%-19.7%) among people living with and without HIV (p-value < 0.01). The prevalence of proteinuria among PLWH versus people without HIV was 43.9% (95% CI:35.8%-52.3%) versus 19.4% (95% CI:13.6%-26.9%) p-value < 0.01. Living with HIV (OR = 3.89(95% CI: 2.04-7.41), p-value < 0.01), older age (OR = 1.13, (95% CI:1.07-1.20), p-value < 0.01), female sex (OR = 1.95, (95% CI:1.06-3.62), p-value = 0.03) and a prior diagnosis of hypertension (OR = 2.19(95% CI:1.02-4.67), p-value = 0.04) were significantly associated with kidney function impairment.

Conclusions

HIV infection is strongly associated with kidney function impairment among older PLWH. Prioritizing routine measurements of kidney function and proteinuria in older PLWH will enable early detection and institution of measures to reduce the progression of kidney disease.

Antibody and Cell-Based Therapies against Virus-Induced Cancers in the Context of HIV/AIDS

Infectious agents, notably viruses, can cause or increase the risk of cancer occurrences. These agents often disrupt normal cellular functions, promote uncontrolled proliferation and growth, and trigger chronic inflammation, leading to cancer. Approximately 20% of all cancer cases in humans are associated with an infectious pathogen. The International Agency for Research on Cancer (IARC) recognizes seven viruses as direct oncogenic agents, including Epstein-Barr Virus (EBV), Kaposi's Sarcoma-associated herpesvirus (KSHV), human T-cell leukemia virus type-1 (HTLV-1), human papilloma virus (HPV), hepatitis C virus (HCV), hepatitis B virus (HBV), and human immunodeficiency virus type 1 (HIV-1). Most viruses linked to increased cancer risk are typically transmitted through contact with contaminated body fluids and high-risk behaviors. The risk of infection can be reduced through vaccinations and routine testing, as well as recognizing and addressing risky behaviors and staying informed about public health concerns. Numerous strategies are currently in pre-clinical phases or undergoing clinical trials for targeting cancers driven by viral infections. Herein, we provide an overview of risk factors associated with increased cancer incidence in people living with HIV (PLWH) as well as other chronic viral infections, and contributing factors such as aging, toxicity from ART, coinfections, and comorbidities. Furthermore, we highlight both antibody- and cell-based strategies directed against virus-induced cancers while also emphasizing approaches aimed at discovering cures or achieving complete remission for affected individuals.

Mapping evidence on barriers to and facilitators of diagnosing noncommunicable diseases (NCDs) among people living with human immunodeficiency virus (PLWH) in low- and middle-income countries (LMICs) in Africa: A scoping review protocol

BACKGROUND

Noncommunicable diseases (NCDs) represent a global public health challenge in all population groups, but the prevalence of major NCDs, such as depression, hypercholesterolemia, hypertension, obesity and diabetes, is increasing at a rapid rate among people living with human immunodeficiency virus (PLWH). Studies show that integrated NCDs and human immunodeficiency virus (HIV) services have improved the patient outcome of PLWH with comorbidities with NCDs. It requires a strengthened and sustainable way of diagnosing major NCDs early among PLWH. However, there is limited evidence regarding the barriers to and facilitators of early diagnosis of NCDs (depression, hypercholesterolemia, hypertension, obesity and diabetes) among PLWH in low- and middle-income countries (LMICs). This review will systematically map the literature and describe the barriers and facilitators of diagnosing NCDs (depression, hypercholesterolemia, hypertension, obesity and diabetes) among PLWH in LMICs in Africa.

METHODS

The methodology presented by Arksey and O'Malley and the recommendation set out by Levac and colleagues will be used. PubMed, MEDLINE with full text via the EBSCO host, Google Scholar, Science Direct and Scopus will be used for a comprehensive search for data extraction. The search will be conducted using keywords, Boolean terms, and Medical Subject Headings (MeSH). All studies with eligible titles will be exported to the EndNote citation manager for deduplication and imported to Rayyan software for screening. Two reviewers will independently screen abstracts, and the preferred reporting items for systematic review and meta-analysis extension to scoping review (PRISMA-Sc) guidelines will be used to guide the search in conducting the scoping review. We will perform descriptive data analysis for quantitative studies, NVivo software version 12 will be used for qualitative studies, and thematic content analysis will be carried out. This scoping review will include studies that included PLWH with those diagnosed with major NCDs (depression, hypercholesterolemia, hypertension, obesity, and diabetes) in LMICs in Africa.

DISCUSSION

This scoping review will highlight evidence mapping on barriers and facilitators of diagnosing NCDs (depression, hypercholesterolemia, hypertension, obesity, and diabetes) among PLWH LMICs in Africa. Scoping Review Registration: registered on Open Science Framework (https://osf.io/xvtwd/).

Incidence and mortality of non-AIDS-defining cancers among people living with HIV: A systematic review and meta-analysis

Background

Non-AIDS-defining cancers (NADCs) are now becoming a rising cause of morbidity among people living with HIV (PLHIV) in the highly active antiretroviral therapy (HAART) era. We conducted a systematic review and meta-analysis to estimate the summary risk of incidence and mortality of a wide range of NADCs among PLHIV compared with the general population.

Methods

This systematic review and meta-analysis was registered in the PROSPERO (registration number CRD42020222020). We searched PubMed, EMBASE, Cochrane library, and Web of Science for relevant studies published before Jan 24, 2022. Cohort or registry linkage studies comparing the incidence or mortality of individual NADCs in PLHIV with that in the general population were included. Studies simply reporting outcomes of cancer precursor lesions or combined NADCs were excluded. We calculated pooled standardised incidence (SIRs) and standardised mortality ratios (SMRs) and their 95% confidence intervals (CIs) using random-effects models, and used robust variance estimation to account for non-independence in study-level effect sizes.

Findings

We identified 92 publications arising from 46 independent studies including 7 articles out of 7 studies from developing countries. Among the 40 types of NADCs investigated, all of the 20 infection-related NADCs, cancers related with human papillomavirus infection in particular, and half of the 20 non-infection-related NADCs occurred in excess in PLHIV compared with the general population. This risk pattern was consistent in most WHO regions and in both high-income and low-and middle-income countries. The increased SIRs for various NADCs were more evident among PLHIV with advanced immunodeficiency, and was explored by HIV transmission route, and use of HAART. PLHIV had increased mortality for anal cancer (SMR 124·07, 95% CI 27·31-563·72), Hodgkin lymphoma (41·03, 2·91-577·88), liver cancer (8·36, 3·86-18·11), lung cancer (3·95, 1·52-10·26), and skin melanoma (3·95, 1·28-12·2).

Interpretation

PLHIV had increased incidence and mortality for a wide spectrum of NADCs. Primary prevention and effective treatment for NADCs in this population is urgently needed.

Understanding older peoples' chronic disease self-management practices and challenges in the context of grandchildren caregiving: A qualitative study in rural KwaZulu-Natal, South Africa

While chronic diseases are amongst the major health burdens of older South Africans, the responsibilities of caring for grandchildren, by mostly grandmothers, may further affect older people's health and well-being. There is a paucity of information about chronic disease self-management for older people in the context of grandchildren caregiving in sub-Saharan Africa. Guided by the Self-Management Framework, the purpose of this qualitative methods study was to explore the chronic disease self-management practices and challenges of grandparent caregivers in rural KwaZulu-Natal, South Africa. Eighteen repeat in-depth interviews were carried out with six grandparent caregivers aged 56 to 80 years over 12 months. Thematic analysis was conducted based on the Self-Management Framework. Pathways into self-management of chronic illnesses were identified: living with a chronic illness, focusing on illness needs, and activating resources. Self-perceptions of caregiving dictated that grandmothers, as women, have the responsibility of caring for grandchildren when they themselves needed care, lived in poverty, and with chronic illnesses that require self-management. However, despite the hardship, the gendered role of caring for grandchildren brought meaning to the grandmothers' lives and supported self-management due to the reciprocal relationship with grandchildren, although chronic illness self-management was complicated where relationships between grandmothers and grandchildren were estranged. The study findings demonstrate that grandchildren caregiving and self-management of chronic conditions are inextricably linked. Optimal self-management of chronic diseases must be seen within a larger context that simultaneously addresses chronic diseases, while paying attention to the intersection of socio-cultural factors with self-management.

Pattern of abnormalities amongst chest X-rays of adults undergoing computer-assisted digital chest X-ray screening for tuberculosis in Peri-Urban Blantyre, Malawi: A cross-sectional study

BACKGROUND

The prevalence of diseases other than tuberculosis (TB) detected during chest X-ray screening is poorly described in sub-Saharan Africa. Computer-assisted digital chest X-ray technology is available for TB screening and has the potential to be a screening tool for non-communicable diseases as well. Low- and middle-income countries are in a transition period where the burden of non-communicable diseases is increasing, but health systems are mainly focused on addressing infectious diseases.

METHODS

Participants were adults undergoing computer-assisted chest X-ray screening for tuberculosis in a community-wide tuberculosis prevalence survey in Blantyre, Malawi. Adults with abnormal radiographs by field radiographer interpretation were evaluated by a physician in a community-based clinic. X-ray classifications were compared to classifications of a random sample of normal chest X-rays by radiographer interpretation. Radiographic features were classified using WHO Integrated Management for Adult Illnesses (IMAI) guidelines. All radiographs taken at the screening tent were analysed by the Qure.ai qXR v2.0 software.

RESULTS

5% (648/13,490) of adults who underwent chest radiography were identified to have an abnormal chest X-ray by the radiographer. 387 (59.7%) of the participants attended the X-ray clinic, and another 387 randomly sampled normal X-rays were available for comparison. Participants who were referred to the community clinic had a significantly higher HIV prevalence than those who had been identified to have a normal CXR by the field radiographer (90 [23.3%] vs. 43 [11.1%] p-value < 0.001). The commonest radiographic finding was cardiomegaly (20.7%, 95% CI 18.0-23.7). One in five (81/387) chest X-rays were misclassified by the radiographer. The overall mean Qure.ai qXR v2.0 score for all reviewed X-rays was 0.23 (SD 0.20). There was a high concordance of cardiomegaly classification between the physician and the computer-assisted software (109/118, 92.4%).

CONCLUSION

There is a high burden of cardiomegaly on a chest X-ray at a community level, much of which is in patients with diabetes, heart disease and high blood pressure. Cardiomegaly on chest X-ray may be a potential tool for screening for cardiovascular NCDs at the primary care level as well as in the community.

Factors associated with prognostic or treatment outcomes in HIV/AIDS patients with and without hypertension in Eswatini

Non-communicable diseases are increasing faster in HIV/AIDS patients than in the general population. We studied the association between hypertension and other possible confounding factors on viral load and CD4-cell counts in hypertensive and non-hypertensive HIV/AIDS patients receiving antiretroviral therapy (ART) at a large hospital in Eswatini over a 4-year period. We performed a retrospective longitudinal review of the medical records of 560 ART patients divided into non-hypertension and hypertension groups (n = 325 and n = 235) from July 27 to September 8, 2018. Generalized Estimated Equation was used to analyze the longitudinal data. Hypertensive patients were more likely to have improved CD4-cell counts than non-hypertensive patients (OR = 1.83, [1.37–2.44]). ART patients with hypertension were more likely to have detectable viral loads, though not significant (OR = 1.37 [0.77–2.43]). In non-hypertensive patients, second line ART was significantly associated with viral load (OR = 8.61 [2.93–25.34]) and adverse side effects (OR = 3.50 [1.06–11.54]), while isoniazid preventive therapy was significantly associated with CD4-cell counts (OR = 1.68 [1.16–2.45]). In hypertensive patients, factors associated with viral load were WHO HIV stage (OR = 2.84 [1.03–7.85]) and adherence (OR = 8.08 [1.33–49.04]). In both groups, CD4-cell counts significantly and steadily increased over time (p-value < 0.001). Results show a significant association between hypertension and CD4 cell counts but not viral load. In ART patients with and without hypertension, the factors associated with prognostic markers were different. More attention may need to be paid to ART patients with well controlled HIV status to monitoring and controlling of hypertension status.

Characteristics of Motor Dysfunction in Longstanding Human Immunodeficiency Virus

BACKGROUND

Cognitive dysfunction in human immunodeficiency virus (HIV) has decreased, but milder forms of HIV-associated neurocognitive disorders (HAND) persist along with motor dysfunction. The HIV Motor Scale (HMS) is a validated tool that captures motor abnormalities on routine neurologic examination and which is associated with cognitive impairment in HIV. In this study, we applied a modified HMS (MHMS) to a nationwide cohort of people with longstanding HIV to characterize and understand the factors contributing to motor dysfunction.

METHODS

The National NeuroAIDS Tissue Consortium is a nationwide longitudinal cohort study. Participants undergo regular assessments including neurological examination, neuropsychological testing, and immunovirologic data collection. Data from examinations were used to calculate the MHMS score, which was then correlated with history of AIDS-related central nervous system (CNS) disorders (ARCD; eg, prior CNS opportunistic infection), cerebrovascular disease (CVD), and HAND.

RESULTS

Sixty-nine percent of participants showed an abnormality on the MHMS, with 27% classified as severe. Results did not vary based on demographic or immunologic variables. The most common abnormalities seen were gait (54%), followed by coordination (39%) and strength (25%), and these commonly co-occurred. CVD (P = .02), history of ARCD (P = .001), and HAND (P = .001) were all associated with higher (ie, worse) HMS in univariate analyses; CVD and ARCD persisted in multivariate analyses. CVD was also marginally associated with symptomatic HAND.

CONCLUSIONS

Complex motor dysfunction remains common in HIV and is associated with CVD, ARCD, and to a lesser extent, HAND. Future studies are needed to understand the longitudinal trajectory of HIV-associated motor dysfunction, its neural substrates, and impact on quality of life.

COVID-19 AND STIGMATISATION OF HEALTHCARE PROVIDERS

The aim: this study presents a Coronavirus Stigma Scale for Healthcare Providers that indicates the social stigmatisation rate and severity toward healthcare providers to a certain extent. This paper aims at raising awareness on the stigmatisation of healthcare providers who sacrifice their own lives for patients diagnosed or are at risk of being infected with COVID-19. Methods: the study uses a 12-item 5-point Likert-type Coronavirus Stigma Scale for Healthcare Providers, which was constructed based on the previously shortened and modified HIV Stigma Scale. The scale was distributed online to healthcare providers, and all the results obtained were then saved to an Excel file. Correlations were determined by using ANOVA and the independent t-test. Percentages, averages, figures and rates were calculated with SPSS. Results: the population of the study comprised 136 participants in total; 40 male and 96 female. Reliability and validity studies were conducted using Cronbach’s alpha and factor analysis. The stigmatisation rate toward healthcare providers was found to be significantly high, and the stigmatisation level was found to increase significantly with increasing age (p<0.05). Conclusions: the mistreatment of stigmatised healthcare providers during a pandemic where the need for them is elevated results in adverse outcomes; therefore, anti-stigma programmes need to be developed. It would be wise to find solutions such as acknowledging the stigma and introducing anti-stigma programmes.

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.

Frequency of non-communicable diseases in people 50 years of age and older receiving HIV care in Latin America

BACKGROUND

A growing population of older adults with HIV will increase demands on HIV-related healthcare. Nearly a quarter of people receiving care for HIV in Latin America are currently 50 years or older, yet little is known about the frequency of comorbidities in this population. We estimated the prevalence and incidence of non-communicable diseases (NCDs) among people 50 years of age or older (≥50yo) receiving HIV care during 2000-2015 in six centers affiliated with the Caribbean, Central and South American network for HIV epidemiology (CCASAnet).

METHODS

We estimated the annual prevalence, and overall prevalence and incidence of cardiovascular diseases, diabetes, hypertension, dyslipidemia, psychiatric disorders, chronic liver and renal diseases, and non-AIDS-defining cancers, and multimorbidity (more than one NCD) of people ≥50yo receiving care for HIV. Analyses were performed according to age at enrollment into HIV care (<50yo and ≥50yo).

RESULTS

We included 3,415 patients ≥50yo, of whom 1,487(43%) were enrolled at age ≥50 years. The annual prevalence of NCDs increased from 32% to 68% and multimorbidity from 30% to 40% during 2000-2015. At the last registered visit, 53% of patients enrolled <50yo and 50% of those enrolled ≥50yo had at least one NCD. Most common NCDs at the last visit in each age-group at enrollment were dyslipidemia (36% in <50yo and 28% in ≥50yo), hypertension (17% and 18%), psychiatric disorders (15% and 10%), and diabetes (11% and 12%).

CONCLUSIONS

The prevalence of NCDs and multimorbidity in people ≥50 years receiving care for HIV in CCASAnet centers in Latin America increased substantially in the last 15 years. Our results make evident the need of planning for provision of complex, primary care for aging adults living with HIV.

HIV Prevalence and Morbidity in Older Inpatients in a High HIV Prevalence Setting

Understanding of the burden of HIV infection and comorbid conditions in older adults is limited, especially in low- and middle-income countries. Antiretroviral therapy (ART) has increased longevity of HIV-positive individuals, making age-related comorbidities more likely. This study aimed to compare the demographic and disease profiles, including chronic comorbid conditions of inpatients, at least 50 years of age, by HIV status, admitted to a regional hospital in South Africa. Adults, 50 years of age and older, admitted to internal medicine wards from November 2015 to February 2016 were approached to participate. Sociodemographic data, laboratory results, anthropometric data, discharge diagnoses, and HIV status were collected and compared by HIV serostatus. Overall, 151 participants were enrolled. Their median age was 61 years (IQR: 56-68 years); 89 (58.9%) were women. Overall, 47 (31.1%) were HIV positive, of whom 10 (6.6%) were first diagnosed during the admission. HIV-positive inpatients were younger than HIV-negative patients. The leading discharge diagnoses of all participants were acute gastroenteritis (11.5%) and community-acquired pneumonia (11.5%). Hypertension and type 2 diabetes mellitus (T2DM) were the leading comorbidities in both HIV-negative and HIV-positive participants. Prevalence of hypertension was 75.0% in seronegative, 59.5% in those with a prior diagnosis of HIV, and 40.0% in newly diagnosed; similarly, prevalence of T2DM was 22.1% in HIV-negative and 24.3% in known HIV-positive participants. Similar proportions died during admission; 11.3% of HIV-negative and 12.7% of HIV-positive admitted inpatients died. Almost one third of patients admitted were HIV positive. In HIV-positive older admitted to hospital, the leading cause for hospitalization was coinfections. In the ART era, irrespective of HIV status, older patients have similar age-related chronic illnesses and similar mortality rates, despite younger age at admission.

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.

Oral Microbiome in HIV-Infected Women: Shifts in the Abundance of Pathogenic and Beneficial Bacteria Are Associated with Aging, HIV Load, CD4 Count, and Antiretroviral Therapy

Human immunodeficiency virus (HIV)-associated nonacquired immunodeficiency syndrome (AIDS) conditions, such as cardiovascular disease, diabetes, osteoporosis, and dementia are more prevalent in older than in young adult HIV-infected subjects. Although the oral microbiome has been studied as a window into pathogenesis in aging populations, its relationship to HIV disease progression, opportunistic infections, and HIV-associated non-AIDS conditions is not well understood. We utilized 16S rDNA-based pyrosequencing to compare the salivary microbiome in three groups: (1) Chronically HIV-infected women >50 years of age (aging); (2) HIV-infected women <35 years of age (young adult); and (3) HIV-uninfected age-matched women. We also examined correlations between salivary dysbiosis, plasma HIV RNA, CD4⁺ T cell depletion, and opportunistic oral infections. In both aging and young adult women, HIV infection was associated with salivary dysbiosis characterized by increased abundance of Prevotella melaninogenica and Rothia mucilaginosa. Aging was associated with increased bacterial diversity in both uninfected and HIV-infected women. In HIV-infected women with oral coinfections, aging was also associated with reduced abundance of the common commensal Veillonella parvula. Patients taking antiretroviral therapy showed increased numbers of Neisseria and Haemophilus. High plasma HIV RNA levels correlated positively with the presence of Prevotella and Veillonella, and negatively with the abundance of potentially beneficial Streptococcus and Lactobacillus. Circulating CD4⁺ T cell numbers correlated positively with the abundance of Streptococcus and Lactobacillus. Our findings extend previous studies of the role of the microbiome in HIV pathogenesis, providing new evidence that HIV infection is associated with a shift toward an increased pathogenic footprint of the salivary microbiome. Taken together, the data suggest a complex relationship, worthy of additional study, between chronic dysbiosis in the oral cavity, aging, viral burden, CD4⁺ T cell depletion, and long-term antiretroviral therapy.

Comparative Assessment of the Magnitude of Hyperlipidemia in HIV-Infected Patients Receiving Lopinavir/r- and Atazanavir/r-Based Antiretroviral Drugs

OBJECTIVE

To assess prevalence of hyperlipidemia in patients receiving lopinavir boosted with ritonavir (LPV/r) and atazanavir boosted with ritonavir (ATV/r) antiretroviral drugs.

METHODS

HIV-infected patients (300) were recruited in the study between December 2015 and April 2016. Lipid profile including triglycerides (TG), high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol (LDL-C) were assessed.

RESULTS

Prevalence of derangement in TG was 71.0% in patients using LPV/r compared to 44% in those using ATV/r ( P = .01). Use of LPV/r was independently associated with increased total cholesterol (TC; P = .001) and TG ( P = .0003). Females had raised levels of TC compared to males ( P = .00008). Body mass index of ≥ 25 kg/m2 was also associated with raised TC ( P = .002) and LDL-C ( P = .006).

CONCLUSION

LPV/r was significantly associated with lipid derangements, indicating the need to regularly monitor lipid profile in patients using LPV/r.

Avoidable workload of care for patients living with HIV infection in Abidjan, Côte d'Ivoire: A cross-sectional study

OBJECTIVE

People living with HIV infection (PLWHIV) in Sub-Saharan Africa cope with an increasing workload of care (doctor visits, lab tests, medication management, refills, etc.) in a context of poor health service organization. We aimed to describe the workload of care for PLWHIV in Sub-Saharan Africa and assess to what extent simple adjustments in care organization could reduce this workload of care.

METHODS

Adult PLWHIV under antiretroviral treatment for at least 1 year were recruited in three centers (two public, one private) in Abidjan, Côte d'Ivoire. Using methods inspired from sociology, we precisely described all health-related activities (HRAs) performed by patients, in 1 month, in terms of time, money and opportunity costs. Then, we assessed the theoretical avoidable workload of care if patients' visits and tests had been grouped on the same days.

RESULTS

We enrolled 476 PLWHIV in the study. Patients devoted 6.7 hours (SD = 6.3), on average, in HRAs per month and spent 5% (SD = 11) of their monthly revenue, on average, on health activities. However, we found great inter-patient heterogeneity in the mixture of activities performed (managing medications; dietary recommendations; visits, tests, support groups; administrative tasks; etc.) and their time allocation, temporal dispersion and opportunity costs (personal, familial, social or professional costs). For 22% of patients, grouping activities on the same days could reduce both time and cost requirements by 20%.

CONCLUSION

PLWHIV in Côte d'Ivoire have a heavy workload of care. Grouping visits and tests on the same days may be a simple and feasible way to reduce patients' investment of time and money in their care.

Behavioral and cognitive interventions to improve treatment adherence and access to HIV care among older adults in sub-Saharan Africa: an updated systematic review

BACKGROUND

Approximately 14% of Africans infected with HIV are over the age of 50, yet few intervention studies focus on improving access to care, retention in care, and adherence to antiretroviral therapy (ART) in this population. A review of the published literature until 2012, found no relevant ART management and care interventions for older people living with HIV (OPLHIV) in sub-Saharan Africa. The aim of this systematic review is to update the original systematic review of intervention studies on OPLHIV, with a focus on evidence from sub-Saharan Africa.

METHODS

We conducted a systematic review of the available published literature from 2012 to 2017 to explore behavioral and cognitive interventions addressing access to ART, retention in HIV care and adherence to ART in sub-Saharan Africa that include older adults (50+). We searched three databases (MEDLINE, EMBASE, and Education Resources Information Center) using relevant Medical Subject Headings (MeSH) terms as well as a manual search of the reference lists. No language restrictions were placed. We identified eight articles which were analyzed using content analysis with additional information obtained directly from the corresponding authors.

RESULTS AND DISCUSSION

There were no studies that exclusively focused on OPLHIV. Three studies referred only to participants being over 18 years and did not specify age categories. Therefore, it is unclear whether these studies actively considered people living with HIV over the age of 50. Although the studies sampled older adults, they lacked sufficient data to draw conclusions about the relevance of the outcomes of this group.

CONCLUSIONS

These findings underscore the need to increase the evidence-base of which interventions will work for older Africans on ART.

Palliative care as an essential component of the HIV care continuum

Although antiretroviral therapy has reduced mortality among people with HIV, inadequate treatment coverage, ageing, and the increasing incidence of organ failure and malignancies mean that high-quality care should include care at the end of life. This Review summarises the epidemiology of HIV in relation to mortality, and the symptoms and concerns of people with AIDS and those living with HIV who have either related or unrelated advanced comorbidities. In response to the evidence of a need for palliative care, the principles and practice of palliative care are described, and the evidence for its effectiveness and cost-effectiveness is appraised. The core practices of palliative care offer a mechanism to enhance the person-centred nature of HIV care; I identify the gaps in this type of care, and present evidence for effective models of care to address these. I detail the policies that prompt governments and health systems to respond to the palliative care needs of their population. Finally, I conclude this Review with evidence-based recommendations to improve the delivery of, and access to, high-quality HIV care until the end of life, reducing unnecessary suffering while optimising person-centred outcomes.

A scoping review of the role of HIV-related stigma and discrimination in noncommunicable disease care

Background

People living with HIV are increasingly burdened by noncommunicable diseases (NCDs) as a result of the NCD susceptibility that accompanies increased life expectancy and the rising global prevalence of NCDs. Health systems are being strengthened and programs are being developed to address this burden, often building on HIV care strategies and infrastructure or through integrated care models. HIV remains a stigmatized condition and the role of HIV stigma in the provision of NCD care is not well understood.

Methods

We conducted a scoping literature review of both peer reviewed and grey literature to identify evidence of the role of HIV stigma in the NCD-care continuum (prevention, diagnosis, care seeking, retention in care, and adherence to treatment of NCDs). We searched PsychInfo and Pubmed and conducted additional searches of programmatic reports and conference abstracts. Included studies were published in English within the past decade and examined HIV-related stigma as it relates to NCD-care or to integrated NCD-and HIV-care programs.

Results

Sixteen articles met the inclusion criteria. Findings suggest: fear of disclosure, internalized shame and embarrassment, and negative past experiences with or negative perceptions of health care providers negatively influence engagement with NCD care; HIV stigma can adversely affect not only people living with HIV in need of NCD care, but all NCD patients; some NCDs are stigmatized in their own right or because of their association with HIV; integrating NCD and HIV care can both reduce stigma for people living with HIV and a present a barrier to access for NCD care.

Conclusion

Due to the dearth of available research and the variability in initial findings, further research on the role of HIV stigma in the NCD-care continuum for people living with HIV is necessary. Lessons from the field of HIV-stigma research can serve as a guide for these efforts.

Comorbidities and the use of comedications in people living with HIV on antiretroviral therapy in Japan: a cross-sectional study using a hospital claims database

OBJECTIVES

To investigate the prevalence of chronic comorbidities and the use of comedications in people living with HIV (PLWH) and on antiretrovirals in Japan, by using a hospital claims database.

DESIGN

Observational, retrospective, cross-sectional study.

SETTING

A hospital claims database of Japanese hospitals that have advanced medical treatment capabilities (ie, advanced treatment hospitals, general hospitals, acute care hospitals), which include those providing acute and chronic care (excluding nursing homes or hospices).

PARTICIPANTS

A total of 1445 PLWH aged ≥18 years and with a prescription record of antiretrovirals between January 2010 and December 2015 were identified from the database.

OUTCOME MEASURES

The number and types of chronic comorbidities, as well as the number and types of comedications, in different age groups of the PLWH.

RESULTS

The median (range) age of patients was 45 (18-90) years, and 90.4% were men. Of the 1445 patients, 972 (67.3%) had at least one chronic comorbidity. Common chronic comorbidities included lipid disorders (31.6%), diabetes (26.8%), hypertension (18.2%) and hepatitis B/C coinfection (18.2%). Patients in the older age groups had greater numbers of chronic comorbidities. The most common chronic comorbidities in the older age groups were hypertension, diabetes and lipid disorders. The majority of patients used at least one comedication, and those in the older age groups used greater numbers of comedications. The most common therapeutic category of comedication included antacids, antiflatulents and antiulcerants (31.7%). Of 151 malignancies reported in 117 patients, 84 were AIDS-defining cancers and 67 were non-AIDS-defining cancers.

CONCLUSIONS

Chronic comorbidities and comedications were common among PLWH in Japan taking antiretrovirals; particularly among older patients, who more frequently used comedications. This suggests the need for giving special attention to the appropriate management of this patient population.

Long-term clinical, immunological and virological outcomes of patients on antiretroviral therapy in southern Myanmar

Objective

To study the long-term clinical, immunological and virological outcomes among people living with HIV on antiretroviral therapy (ART) in Myanmar.

Methods

A retrospective analysis of people on ART for >9 years followed by a cross-sectional survey among the patients in this group who remained on ART at the time of the survey. Routinely collected medical data established the baseline clinical and demographic characteristics for adult patients initiating ART between 2004 and 2006. Patients remaining on ART between March-August 2015 were invited to participate in a survey assessing clinical, virological, immunological, and biochemical characteristics.

Results

Of 615 patients included in the retrospective analysis, 35 (6%) were lost-to-follow-up, 9 (1%) were transferred, 153 died (25%) and 418 (68%) remained active in care. Among deaths, 48 (31.4%) occurred within 3 months of ART initiation, and 81 (52.9%) within 12 months, 90.1% (n = 73) of which were initially classified as stage 3/4. Of 385 patients included in the survey, 30 (7.7%) were on second-line ART regimen; 373 (96.8%) had suppressed viral load (<250 copies/ml). The mean CD4 count was 548 cells/ mm3 (SD 234.1) after ≥9 years on treatment regardless of the CD4 group at initiation. Tuberculosis while on ART was diagnosed in 187 (48.5%); 29 (7.6%) had evidence of hepatitis B and 53 (13.9%) of hepatitis C infection.

Conclusions

Appropriate immunological and virological outcomes were seen among patients on ART for ≥9 years. However, for the complete initiating cohort, high mortality was observed, especially in the first year on ART. Concerning co-infections, tuberculosis and viral hepatitis were common among this population. Our results demonstrate that good long-term outcomes are possible even for patients with advanced AIDS at ART initiation.

Chronicity, crisis, and the 'end of AIDS'

In biomedical, public health, and popular discourses, the 'end of AIDS' has emerged as a predominant way to understand the future of HIV research and prevention. This approach is predicated on structuring and responding to HIV in ways that underscore its presumed lifelong nature. In this article, I examine the phenomenon of HIV chronicity that undergirds the 'end of AIDS' discourse. In particular, I explore how the logic of HIV chronicity, induced by technological advances in treatment and global financial and political investments, intensifies long-term uncertainty and prolonged crisis. Focusing on over 10 years of anthropological and public health research in the United States, I argue that HIV chronicity, and subsequently, the 'end of AIDS' discourse, obscure the on-going HIV crisis in particular global communities, especially among marginalised and ageing populations who live in under-resourced areas. By tracing the 'end of AIDS' discourse in my field sites and in other global locations, I describe how HIV chronicity signals a continuing global crisis and persistent social precarity rather than a 'break' with a hopeless past or a promising future free from AIDS.

HIV-associated changes in the enteric microbial community: potential role in loss of homeostasis and development of systemic inflammation

Supplemental Digital Content is available in the text

Purpose of review

Despite HIV therapy advances, average life expectancy in HIV-infected individuals on effective treatment is significantly decreased relative to uninfected persons, largely because of increased incidence of inflammation-related diseases, such as cardiovascular disease and renal dysfunction. The enteric microbial community could potentially cause this inflammation, as HIV-driven destruction of gastrointestinal CD4⁺ T cells may disturb the microbiota–mucosal immune system balance, disrupting the stable gut microbiome and leading to further deleterious host outcomes.

Recent findings

Varied enteric microbiome changes have been reported during HIV infection, but unifying patterns have emerged. Community diversity is decreased, similar to pathologies such as inflammatory bowel disease, obesity, and Clostridium difficile infection. Many taxa frequently enriched in HIV-infected individuals, such as Enterobacteriaceae and Erysipelotrichaceae, have pathogenic potential, whereas depleted taxa, such as Bacteroidaceae and Ruminococcaceae, are more linked with anti-inflammatory properties and maintenance of gut homeostasis. The gut viral community in HIV has been found to contain a greater abundance of pathogenesis-associated Adenoviridae and Anelloviridae. These bacterial and viral changes correlate with increased systemic inflammatory markers, such as serum sCD14, sCD163, and IL-6.

Summary

Enteric microbial community changes may contribute to chronic HIV pathogenesis, but more investigation is necessary, especially in the developing world population with the greatest HIV burden (Video, Supplemental Digital Content 1, which includes the authors’ summary of the importance of the work).

Non-communicable diseases and HIV care and treatment: models of integrated service delivery

OBJECTIVES

Non-communicable diseases (NCD) are a growing cause of morbidity in low-income countries including in people living with human immunodeficiency virus (HIV). Integration of NCD and HIV services can build upon experience with chronic care models from HIV programmes. We describe models of NCD and HIV integration, challenges and lessons learned.

METHODS

A literature review of published articles on integrated NCD and HIV programs in low-income countries and key informant interviews were conducted with leaders of identified integrated NCD and HIV programs. Information was synthesised to identify models of NCD and HIV service delivery integration.

RESULTS

Three models of integration were identified as follows: NCD services integrated into centres originally providing HIV care; HIV care integrated into primary health care (PHC) already offering NCD services; and simultaneous introduction of integrated HIV and NCD services. Major challenges identified included NCD supply chain, human resources, referral systems, patient education, stigma, patient records and monitoring and evaluation. The range of HIV and NCD services varied widely within and across models.

CONCLUSIONS

Regardless of model of integration, leveraging experience from HIV care models and adapting existing systems and tools is a feasible method to provide efficient care and treatment for the growing numbers of patients with NCDs. Operational research should be conducted to further study how successful models of HIV and NCD integration can be expanded in scope and scaled-up by managers and policymakers seeking to address all the chronic care needs of their patients.

Relationship Between HIV Infection, Antiretroviral Therapy, Inflammatory Markers, and Cerebrovascular Endothelial Function Among Adults in Urban China

BACKGROUND

Cerebrovascular risk is increased in people living with HIV infection compared with age-matched uninfected individuals. Cerebrovascular endothelial dysfunction related to antiretroviral therapy (ART) and inflammation may contribute to higher stroke risk in HIV infection.

METHODS

We compared cerebral vasoreactivity-a measure of cerebrovascular endothelial function assessed by the breath-holding index (BHI) using transcranial Doppler ultrasound-between virologically suppressed Chinese HIV-infected individuals followed in an HIV clinic in Beijing, China, and uninfected controls. We constructed mixed-effects models to evaluate the association of HIV, ART, and inflammatory markers with cerebral vasoreactivity.

RESULTS

In an unadjusted model, HIV infection was associated with a trend toward lower cerebral vasoreactivity (BHI 1.08 versus 1.26, P = 0.079). In multivariable analyses, cholesterol modified the association between HIV infection and cerebral vasoreactivity (P = 0.015 for interaction). At a lower total cholesterol of 4.15 mmol/L, HIV was associated with lower cerebral vasoreactivity (BHI -0.28, P = 0.019), whereas at a cholesterol of 5.15 mmol/L, the reduction in cerebral vasoreactivity associated with HIV was no longer statistically significant (BHI -0.05, P = 0.64). Among HIV-infected individuals, use of lopinavir/ritonavir compared with efavirenz was associated with lower cerebral vasoreactivity (BHI -0.24, P = 0.040). We did not find a significant association between inflammatory markers and cerebral vasoreactivity.

CONCLUSIONS

Cerebrovascular endothelial dysfunction associated with HIV infection may be most relevant for individuals with less traditional vascular risk, such as those with lower cholesterol. Further study of the impact of ART on cerebrovascular endothelial function is warranted to aid with ART selection in individuals at high cerebrovascular risk.

Incidence and predictors of hypertension in adults with HIV-initiating antiretroviral therapy in south-western Uganda

OBJECTIVE

The successful scale-up of antiretroviral therapy (ART) in sub-Saharan Africa has led to increasing life expectancy, and thus increased risk of hypertension. We aimed to describe the incidence and predictors of hypertension in HIV patients receiving ART at a publicly funded clinic in rural Uganda.

METHODS

We abstracted data from medical records of adult patients who initiated ART at an HIV clinic in south-western Uganda during 2010-2012. We defined hypertension as at least two consecutive clinical visits, with a SBP at least 140 mmHg and/or SBP of at least 90 mmHg, or prescription for an antihypertensive medication. We calculated the incidence of hypertension and fit multivariable Cox proportional-hazards models to identify predictors of hypertension.

RESULTS

A total of 3389 patients initiated ART without a prior diagnosis of hypertension during the observation period. Over 3990 person-years of follow-up, 445 patients developed hypertension, for a crude incidence of 111.5/1000 (95% confidence interval 101.9-121.7) person-years. Rates were highest among men aged at least 40 years (158.8 per/1000 person-years) and lowest in women aged 30-39 years (80/1000 person-years). Lower CD4 cell count at ART initiation, as well as traditional risk factors including male sex, increasing age, and obesity, were independently associated with hypertension.

CONCLUSION

We observed a high incidence of hypertension in HIV-infected persons on ART in rural Uganda, and increased risk with lower nadir CD4 cell counts. Our findings call for increased attention to screening of and treatment for hypertension, along with continued prioritization of early ART initiation.

Chronic disease, risk factors and disability in adults aged 50 and above living with and without HIV: findings from the Wellbeing of Older People Study in Uganda

BACKGROUND

Data on the prevalence of chronic conditions, their risk factors, and their associations with disability in older people living with and without HIV are scarce in sub-Saharan Africa.

OBJECTIVES

In older people living with and without HIV in sub-Saharan Africa: 1) to describe the prevalence of chronic conditions and their risk factors and 2) to draw attention to associations between chronic conditions and disability.

METHODS

Cross-sectional individual-level survey data from people aged 50 years and over living with and without HIV were analyzed from three study sites in Uganda. Diagnoses of chronic conditions were made through self-report, and disability was determined using the WHO Disability Assessment Schedule (WHODAS). We used ordered logistic regression and calculated predicted probabilities to show differences in the prevalence of multiple chronic conditions across HIV status, age groups, and locality. We used linear regression to determine associations between chronic conditions and the WHODAS.

RESULTS

In total, 471 participants were surveyed; about half the respondents were living with HIV. The prevalence of chronic obstructive pulmonary disease and eye problems (except for those aged 60-69 years) was higher in the HIV-positive participants and increased with age. The prevalence of diabetes and angina was higher in HIV-negative participants. The odds of having one or more compared with no chronic conditions were higher in women (OR 1.6, 95% CI 1.1-2.3) and in those aged 70 years and above (OR 2.1, 95% CI 1.2-3.6). Sleep problems (coefficient 14.2, 95% CI 7.3-21.0) and depression (coefficient 9.4, 95% CI 1.2-17.0) were strongly associated with higher disability scores.

CONCLUSION

Chronic conditions are common in older adults and affect their functioning. Many of these conditions are not currently addressed by health services in Uganda. There is a need to revise health care policy and practice in Uganda to consider the health needs of older people, particularly as the numbers of people living into older age with HIV and other chronic conditions are increasing.

Chronic alcohol increases CD8+ T-cell immunosenescence in simian immunodeficiency virus-infected rhesus macaques

Activated CD8+ T-cells correlate with viral load and may foretell antiretroviral therapy (ART) failure. HIV infection has been suggested to accelerate immunosenescence through chronic persistent inflammation. Alcohol-use disorders (AUD) are prevalent in persons living with HIV/AIDS (PLWHA). We tested the hypothesis that hazardous alcohol consumption accelerates immune activation and immunosenescence. Immune activation and immunosenescence were examined in CD8+ T lymphocytes (CD3+CD4-CD8+) isolated from intestinal biopsies, axillary lymph nodes, and peripheral blood mononuclear cells (PBMCs) of chronic binge alcohol (CBA)-consuming simian immunodeficiency virus (SIV)-infected male rhesus macaques with and without antiretroviral therapy (ART; CBA/ART+, CBA/ART-) and in PBMCs isolated from a cohort of PLWHA. Polychromatic flow cytometry was used to phenotype cells isolated from intestinal biopsies, lymph nodes, and peripheral blood from rhesus macaques and PLWHA. The Alcohol Use Disorders Identification Test (AUDIT) identified hazardous alcohol drinking in PLWHA. Viral load was determined by RT-qPCR and telomere length was measured using qPCR. PBMC CD8+ T-cell activation (CD38+HLA-DR+) and immunosenescence (CD28-) were increased over baseline levels (857% ± 334, p < 0.05; 398% ± 80, p < 0.05, respectively) only in CBA animals not receiving ART. Viral load correlated with CD8+ T-cell immunosenescence in macaque PBMCs (r(s) = 0.49, p = 0.02). Activated immunosenescent T-cell (CD8+CD38+CD28-) frequencies in PBMCs from PLWHA significantly correlated with AUDIT scores (r(s) = 0.75, p = 0.001), while no correlation was observed with CD4+ T-cell and AUDIT scores (r(s) = -0.24, p = 0.38). Activated immunosenescent T-cells had shorter telomeres than CD8+ T-cells (CD8+CD28+) from PLWHA. Our results suggest that CBA and AUD augment immune activation and immunosenescence in SIV-infected macaques and PLWHA.

Inhibition of HIV-1 gp41 expression with hammerhead ribozymes

Despite great progress in the treatment of AIDS, HIV-1 remains one of the major concerns as a human pathogen. One of the therapeutic strategies against viral infections is the application of catalytic ribonucleic acids (ribozymes) that can significantly reduce expression of a target gene by site-specific hydrolysis of its mRNA. In the present paper, we report a study on the activity of several variants of hammerhead ribozymes targeting a conserved region within mRNA encoding HIV-1 envelope glycoprotein gp41. On the basis of the data from in vitro assays and gene silencing in the cultured cells, we propose a new hammerhead ribozyme targeting the gp41-encoding sequence that can be potentially used as a therapeutic agent in AIDS treatment. Moreover, we demonstrate that the hydrolytic activity of the ribozyme in the intracellular environment cannot be inferred solely from the results of in vitro experiments.

Magnitude and risk factors of non-communicable diseases among people living with HIV in Tanzania: a cross sectional study from Mbeya and Dar es Salaam regions

Background

HIV and Non communicable diseases (NCDs) are major problem of public health importance in developing countries. This study was conducted to explore and establish information on the magnitude, distribution of NCDs risk factors among people living with HIV (PLWHIV) which is scarce in Tanzania.

Method

A cross sectional study was conducted to PLWHIV from 12 care and treatment clinics in Dar es Salaam and Mbeya regions from October 2011 to February 2012. Data on demographic characteristics, NCD risk factors including behavioral, biochemical tests and physical measurements was collected from PLWHIV.

Results

Of 754 PLWHIV recruited, 671(89.0%) consented to participate in the study and 354/671(52.8%) were on antiretroviral therapy (ART). The following NCD risk factors: raised blood levels of low density lipoprotein (61.3% vs 38.7%, p < 0.001) total cholesterol (TC) (71.6% vs 28.4%, p < 0.001) and triglyceride (67.0% vs 33.0%, p = 0.001) as well as overweight/obesity (61.1% vs 38.9%, p = 0.010), abnormal waist circumference (61.7% vs 38.3%, p < 0.001) and being aged >40 years (63.3% vs 36.7%, p < 0.001) were more prevalent among PLWHIV on ART than ART naïve. The prevalence of Diabetes mellitus among PLWHIV was 4.2% and was slightly high among those ART naïve (4.7% vs 3.7%). The prevalence of hypertension was 26.2% and was high among those on ART (30.0% vs 21.9%, p = 0.010). Being aged >40 years (AOR = 2.52, 95% CI 1.37-4.63), abnormal waist circumference (AOR = 2.37 95% CI 1.13-5.00), overweight/obesity (AOR = 2.71, 95% CI 1.26-5.84) and male sex (AOR = 1.17, 1.02-4.20) were the predictors of hypertension among patients on ART while raised TC (AOR = 1.47 (1.01-2.21) and being aged >40 years (AOR = 3.42, 95% CI 2.06-5.70) were predictors for hypertension among ART naïve patients.

Conclusion

This study has revealed that the magnitude of NCD risk factors is significantly higher among PLWHIV on ART than those not on ART. Initiating and strengthening of interventions for minimizing preventable NCD risks should be considered when initiating ART among PLWHIV. Regular monitoring of NCD risk factors is of paramount importance among ART patients.

HIV and noncommunicable disease comorbidities in the era of antiretroviral therapy: a vital agenda for research in low- and middle-income country settings

In this special 2014 issue of JAIDS, international investigator teams review a host of noncommunicable diseases (NCDs) that are often reported among people living and aging with HIV in sub-Saharan Africa. With the longer lifespans that antiretroviral therapy programs have made possible, NCDs are occurring due to a mix of chronic immune activation, medication side effects, coinfections, and the aging process itself. Cancer; cardiovascular and pulmonary diseases; metabolic, body, and bone disorders; gastrointestinal, hepatic, and nutritional aspects; mental, neurological, and substance use disorders; and renal and genitourinary diseases are discussed. Cost-effectiveness, key research methods, and issues of special importance in Asia, Latin America, and the Caribbean are also addressed. In this introduction, we present some of the challenges and opportunities for addressing HIV and NCD comorbidities in low- and middle-income countries, and preview the research agenda that emerges from the articles that follow.

Smoking and experiences with tobacco cessation among men who have sex with men: New Orleans, 2011

Smoking continues to be a problem in the United States, particularly among men who have sex with men (MSM). The current study assesses the prevalence of current and lifetime smoking as well as cessation experiences in a sample of MSM. Two-thirds of the sample had ever smoked tobacco and 50 % of MSM were current smokers. Prevalence of current smoking in this sample was higher than comparative data obtained from HIV positive patients at a local clinical population. Smoking was found to be associated with HIV status, race, age, education, income and alcohol use. A high proportion of MSMs social networks were smokers especially among current smokers. Continued efforts targeting or linking MSM into tobacco cessation efforts are recommended.

The end of AIDS: HIV infection as a chronic disease

The success of antiretroviral therapy has led some people to now ask whether the end of AIDS is possible. For patients who are motivated to take therapy and who have access to lifelong treatment, AIDS-related illnesses are no longer the primary threat, but a new set of HIV-associated complications have emerged, resulting in a novel chronic disease that for many will span several decades of life. Treatment does not fully restore immune health; as a result, several inflammation-associated or immunodeficiency complications such as cardiovascular disease and cancer are increasing in importance. Cumulative toxic effects from exposure to antiretroviral drugs for decades can cause clinically-relevant metabolic disturbances and end-organ damage. Concerns are growing that the multimorbidity associated with HIV disease could affect healthy ageing and overwhelm some health-care systems, particularly those in resource-limited regions that have yet to develop a chronic care model fully. In view of the problems inherent in the treatment and care for patients with a chronic disease that might persist for several decades, a global effort to identify a cure is now underway.

Advocacy resource: engaging the media and promoting your cancer program in Africa

To address the need for a significant increase in cancer advocacy programs in Africa, the University of Florida (UF), the Prostate Net, and the African Organization for Research and Training in Cancer (AORTIC) co-hosted the first biennial International Workshop on Cancer Advocacy for African Countries (CAAC) on November 29, 2011, one-day prior to AORTIC's 8th International Cancer Conference in Cairo, Egypt. Over 70 African cancer advocates representing about 12 African countries participated in this workshop.The primary goal of the one-day workshop was to inform, educate and empower African cancer advocates to increase the promotion of their cancer programs. The first half of the workshop consisted of five formal PowerPoint presentations focused on the following topics: (a) Understanding Your Community and Assessing your Community Health Assets and Needs; (b) Developing a successful advocacy model for your cancer program; (c) Developing a Relationship with your Elected Officials to Advocate Cancer-related Policies; (d) Engaging the Media and promoting your cancer program; and (e) Developing advocacy plans for sustainability. In this article we summarize the informational content given in the PowerPoint presentation entitled "Engaging the Media and promoting your cancer program". The content given in this article is useful as a how-to guide for both the beginner and the experienced cancer advocate who wants to establish/promote a cancer awareness program.

Toward a systemic research agenda for addressing the joint epidemics of HIV/AIDS and noncommunicable diseases

A growing proportion of people living with HIV/AIDS also struggle to cope with one or several noncommunicable diseases (NCDs), particularly as they age. The two epidemics being intertwined, there is increasing recognition that that there should be closer advocacy, policy and programmatic links between HIV and NCDs. The objective of this paper is to discuss the development of a research agenda geared towards informing the design and implementation of programs and policies truly grounded in a co-benefits approach. Tackling the joint epidemics of HIV/AIDS and NCDs in Africa will require for research funders and private and foreign aid donors to be bold, visionary and to commit to long-term research investments in order to evaluate the effects of natural policy experiments and complex interventions.
