Risk of diabetes mellitus in persons with and without HIV: a Danish nationwide population-based cohort study

Examining incidence of diabetes in people with HIV: tracking the shift in traditional and HIV-related risk factors

BACKGROUND AND OBJECTIVE

The risk factors of diabetes mellitus (DM) in people with HIV (PWH) may be dynamic in a life course manner. This study aimed to describe incidence of DM and investigate the trajectory of changes in risk factor associated with DM incidence over around 15 years among a statewide cohort of PWH in South Carolina (SC).

DESIGN

This is a population-based cohort study.

METHODS

Data were retrieved from the integrated statewide electronic health records between 2006 and 2020 in SC. Separate subgroup analysis was conducted according to the patients' different follow up duration (i.e., 5, 10, and 15 years) to observe the evolving risk factors of DM development, using multivariable logistic regressions.

RESULTS

The DM incidence among a total of 9115 PWH was 8.9 per 1000 person-years. In the overall model, being >60 years old, hypertension, and obesity were positively associated with DM while alcohol consumption, years of HIV diagnosis and high percentage days of viral suppression were negatively associated with the outcome. In the subgroup analyses, similar risk factors were observed. The odds of DM increased in a graded fashion with age. Hypertension was positively associated with DM in all groups and retention to care was negatively associated with the outcome in groups 1 and 3.

CONCLUSION

This large-scale population-based study has revealed a relatively lower incidence of DM among PWH than some other US States. The evolving risk factors over time underline the need for maintaining retention to care to prevent the occurrence of DM.

Incidence of prostate cancer in Medicaid beneficiaries with and without HIV in 2001-2015 in 14 states

Background

Prostate cancer is projected to be the most common cancer among people living with HIV; however, incidence of prostate cancer has been reported to be lower in men with HIV compared to men without HIV with little evidence to explain this difference. We describe prostate cancer incidence by HIV status in Medicaid beneficiaries, allowing for comparison of men with and without HIV who are similar with respect to socioeconomic characteristics and access to healthcare.

Methods

Medicaid beneficiaries (N=15,167,636) aged 18-64 with ≥7 months of continuous enrollment during 2001-2015 in 14 US states were retained for analysis. Diagnoses of HIV and prostate cancer were identified using inpatient and other non-drug claims. We estimated cause-specific (csHR) and sub-distribution hazard ratios comparing incidence of prostate cancer by HIV status, adjusted for age, race-ethnicity, state of residence, year of enrollment, and comorbid conditions. Models were additionally stratified by age and race-ethnicity.

Results

There were 366 cases of prostate cancer observed over 299,976 person-years among beneficiaries with HIV and 17,224 cases over 22,298,914 person-years in beneficiaries without HIV. The hazard of prostate cancer was lower in men with HIV than men without HIV (csHR=0.89; 95% CI: 0.80, 0.99), but varied by race-ethnicity, with similar observations among non-Hispanic Black (csHR=0.79; 95% CI: 0.69, 0.91) and Hispanic (csHR=0.85; 95% CI: 0.67, 1.09), but not non-Hispanic white men (csHR=1.17; 95% CI: 0.91, 1.50). Results were similar in models restricted to ages 50-64 and 40-49, except for a higher hazard of prostate cancer in Hispanic men with HIV in their 40s, while the hazard of prostate cancer was higher in men with HIV across all models for men aged 18-39.

Conclusion

Reported deficits in prostate cancer incidence by HIV status may be restricted to specific groups defined by age and race-ethnicity.

HIV and type 2 diabetes: An evolving story

INTRODUCTION

Diabetes is widely reported to be more common in people living with HIV (PLWH). Much of the data supporting this originated during the earlier HIV era. The perceived increased risk of type 2 diabetes is reflected in HIV clinical guidelines that recommend screening for diabetes in PLWH on anti-retroviral therapy (ART). However, international HIV clinical guidelines do not agree on the best marker of glycaemia to screen for diabetes. This stems from studies that suggest HbA1c underestimates glycaemia in PLWH.

METHODS

Within this review we summarise the literature surrounding the association of HIV and type 2 diabetes and how this has changed over time. We also present the evidence on HbA1c discrepancy in PLWH.

CONCLUSION

We suggest there is no basis to any international guidelines to restrict HbA1c based on HIV serostatus. We recommend, using the current evidence, that PLWH should be screened annually for diabetes in keeping with country specific guidance. Finally, we suggest future work to elucidate phenotype and natural history of type 2 diabetes in PLWH across all populations.

Associations of HIV and prevalent type 2 diabetes mellitus in the context of obesity in South Africa

It is unclear how rising obesity among people with HIV (PWH) in sub-Saharan Africa (SSA) impacts their risk of type 2 diabetes mellitus (diabetes). Using a South African national cross-sectional sample of adult PWH and their peers without HIV (PWOH), we examined the associations between HIV and prevalent diabetes across the spectrum of body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WtHR). Analyses were sex stratified, and adjusted for age, sociodemographic and behavioral factors. The prevalence of diabetes among males was similar between PWH and PWOH, overall and at all levels of adiposity. In contrast, overall diabetes prevalence was higher among female PWOH than female PWH. However, there were differences according to adiposity such that, compared to female PWOH, relative diabetes prevalence in female PWH was reduced with obesity but accentuated with leanness. These differences in the relationship between adiposity and diabetes by HIV serostatus call for better mechanistic understanding of sex-specific adipose tissue biology in HIV in South Africa, and possibly in other HIV endemic settings in SSA.

Mechanisms and clinical relevance of the bidirectional relationship of viral infections with metabolic diseases

Viruses have been present during all evolutionary steps on earth and have had a major effect on human history. Viral infections are still among the leading causes of death. Another public health concern is the increase of non-communicable metabolic diseases in the last four decades. In this Review, we revisit the scientific evidence supporting the presence of a strong bidirectional feedback loop between several viral infections and metabolic diseases. We discuss how viruses might lead to the development or progression of metabolic diseases and conversely, how metabolic diseases might increase the severity of a viral infection. Furthermore, we discuss the clinical relevance of the current evidence on the relationship between viral infections and metabolic disease and the present and future challenges that should be addressed by the scientific community and health authorities.

Non-communicable disease comorbidities in HIV patients: diabetes, hypertension, heart disease, and obstructive sleep apnea as a neglected issue

The present study evaluates the non-communicable disease (NCD) patterns and related risk factors among people living with HIV (PLWH) in Iran. This national cross-sectional survey study was conducted on 1173 confirmed PLWHs with a mean age of 35.35 (56.82 Over 50 years old, 33.90 Under 50 years old) admitted from 15 different provinces in the country. Logistic regression was used to analyze the association of factors with having at least one NCD comorbidity. From 1173 PLWH, 225(19.18%) participants experienced at least one NCD (15.20% and 38.69% among under- and over-50-year-old patients, respectively). The prevalence of heart disease, hypertension, diabetes, and sleep apnea among all patients was 1.59%, 2.05%, 1.55%, and 10.26%, respectively. The similar prevalence for each NCD among those over 50 years was 10.11%, 15.71%, 9.01%, 25.44%, and 1.01%, 1.12%, 1.04%, and 9.23% among those under 50 years, respectively. The odds of being at risk of at least one NCD stood higher in patients over 50 years (ORadj = 2.93, 95% CI 1.96-4.37), married (ORadj = 2.48, 95% CI 1.41-4.35), divorced or widowed (ORadj = 2.78, 95% CI 1.48-5.20), and obese (ORadj = 3.82, 95% CI 2.46-5.91). According to our findings regarding the prevalence of NCDs among patients under 50 years of age, we recommend that policymakers give greater consideration to this group in the screening and care programs for NCDs since adults and the elderly are both vulnerable to the risk factors for developing NCDs.

Exploring the Relation Between Diabetes and HIV: A Narrative Review

Diabetes mellitus, more usually abbreviated as DM or just diabetes, is a devastating metabolic disorder that claims many lives every year. Due to various variables, including the aging of the HIV (human immunodeficiency virus)-infected population and the high prevalence of chronic medical conditions among persons living with HIV, the crossroads of DM and HIV infection has become a significant research topic. Although the connection between HIV and diabetes is not simple, many aspects of the virus and its treatment have been connected to the onset of diabetes. The presence of inconclusive evidence that HIV is a risk factor for diabetes makes this area more challenging and debatable. This article examines the prevalence of DM in the HIV-positive community, along with its assessment, management, and treatment objectives. The most recent diabetes treatment recommendations from authoritative groups are considered in this article to give readers thorough and current advice. These guidelines emphasize the importance of tailoring pharmacological therapy and treatment goals to suit the specific needs of individuals with diabetes, including those who are also living with HIV. Individualizing treatment plans ensures that healthcare professionals consider comorbidities, medication interactions, and potential side effects when managing diabetes concerning HIV. In the later part of the article, a holistic approach is discussed to address the increased risk of cardiovascular disease and associated complications in HIV-positive individuals with diabetes. This approach aims to mitigate cardiovascular risks and improve overall health outcomes through comprehensive strategies such as lifestyle modifications, regular monitoring, medication management, and integration of multidisciplinary healthcare teams. By considering the unique challenges and considerations of individuals living with both HIV and diabetes, healthcare providers can develop targeted interventions and provide optimal care. In order to improve the life and health of persons living with HIV and diabetes, the article stresses the significance of cooperation amongst professionals in these fields.

Development of Hypertension and Diabetes Mellitus, and Associated Factors, Among Adult HIV Patients in Ethiopia

Background

Medical improvements and increased access to treatment have turned HIV from a highly fatal disease into a treatable and controllable disease. With the improvement in lifespan, HIV patients face increasing morbidity and mortality from chronic comorbidities (hypertension and diabetes mellitus). There is, nevertheless, a paucity of information on the scale of HIV noncommunicable disease comorbidity and its associated factors. This study aimed to investigate the incidence and predictors of chronic comorbidity in HIV patients in a resource-limited setting.

Methods

A prospective cohort study was conducted from 2019 to 2021. We included 520 HIV patients at baseline. Patients without hypertension or diabetes were followed for two years to determine the incidence of developing comorbidities. Nine trained nurses used a pre-tested structured questionnaire to collect data during routine care consultations in three hospitals in southern Ethiopia. To find predictors of these chronic comorbidities, a multivariable logistic regression analysis was used.

Results

After two years, 54 out of 377 participants, or 14%, had chronic comorbidity, which is defined as having diabetes and/or hypertension. Hypertension (12%) and diabetes (4%), respectively, were observed. When compared to those who were not overweight, the risk of developing chronic comorbidity was three times higher in overweight people [AOR = 3.45, 95% CI: (1.04, 11.45), P = 0.045]. Older participants were about 6 times more likely than younger participants to have chronic comorbidity [AOR = 4.93, 95% CI: (1.56, 15.57), P = 0.007]. Those who did not engage in regular physical activity were twice as likely to develop chronic comorbidity [AOR = 2.16, 95% CI: (1.09, 4.29), P = 0.027].

Conclusion

The incidence of chronic comorbidity was high in the study population. Targeted screening for early signs of chronic comorbidity, nutritional counseling, and awareness creation in regular physical activity programs should be integrated into HIV care to prevent and control chronic comorbidity in resource-limited settings.

Diabetes in HIV: the Link to Weight Gain

PURPOSE OF REVIEW

The burden of metabolic diseases, including type 2 diabetes mellitus (T2DM), is rising among persons with HIV (PWH) on antiretroviral therapy (ART). This increase coincides with an aging population and a greater proportion who are overweight/obese. This review summarizes the changing epidemic of T2DM on contemporary ART, the role of weight gain, and therapeutic options.

RECENT FINDINGS

Recent studies confirm that PWH face an epidemic of obesity and T2DM, similar to the general population. Contemporary ART is associated with greater weight gain and may contribute to the risk of T2DM. Recent advances in medical weight loss therapy offer a way forward in the prevention and treatment of weight-associated T2DM. Weight gain is one of the biggest contributors to T2DM in PWH. Future studies on the role of adipose tissue distribution, adipose tissue function and clinical use of effective weight loss medications may change the paradigm of care for PWH.

Viruses and Endocrine Diseases

Viral infections have been frequently associated with physiological and pathological changes in the endocrine system for many years. The numerous early and late endocrine complications reported during the current pandemic of coronavirus disease 2019 (COVID-19) reinforce the relevance of improving our understanding of the impact of viral infections on the endocrine system. Several viruses have been shown to infect endocrine cells and induce endocrine system disturbances through the direct damage of these cells or through indirect mechanisms, especially the activation of the host antiviral immune response, which may lead to the development of local or systemic inflammation or organ-specific autoimmunity. In addition, endocrine disorders may also affect susceptibility to viral infections since endocrine hormones have immunoregulatory functions. This review provides a brief overview of the impact of viral infections on the human endocrine system in order to provide new avenues for the control of endocrine diseases.

Cardiovascular disease and risk assessment in people living with HIV: Current practices and novel perspectives

Human immunodeficiency virus (HIV) infection represents a major cardiovascular risk factor, and the cumulative cardiovascular disease (CVD) burden among aging people living with HIV (PLWH) constitutes a leading cause of morbidity and mortality. To date, CVD risk assessment in PLWH remains challenging. Therefore, it is necessary to evaluate and stratify the cardiovascular risk in PLWH with appropriate screening and risk assessment tools and protocols to correctly identify which patients are at a higher risk for CVD and will benefit most from prevention measures and timely management. This review aims to accumulate the current evidence on the association between HIV infection and CVD, as well as the risk factors contributing to CVD in PLWH. Furthermore, considering the need for cardiovascular risk assessment in daily clinical practice, the purpose of this review is also to report the current practices and novel perspectives in cardiovascular risk assessment of PLWH and provide further insights into the development and implementation of appropriate CVD risk stratification and treatment strategies, particularly in countries with high HIV burden and limited resources.

Prevalence and risk factors of high cholesterol and triglycerides among people with HIV in Texas

Background

People with HIV (PWH) commonly have elevated cholesterol and triglycerides levels that have been linked to medications. However, healthy behaviors including lifestyle changes can lower high cholesterol (CHOL) or high triglycerides (TG), thereby reducing individual risk for cardiovascular diseases. This study aimed to determine the prevalence and risk factors associated with high CHOL or TG among PWH in Texas.

Methods

Cross-sectional data of 981 PWH from the 2015–2017 Texas and Houston Medical Monitoring Projects were examined. High CHOL or TG was identified by medical chart diagnosis, CHOL or TG medication use, or most recent fasting lab ≥ 200 mg/dl (total CHOL) or ≥ 150 mg/dl (TG). High CHOL or TG associations with sociodemographic and clinical characteristics were assessed using Rao-Scott chi-square tests. Prevalence of high CHOL or TG development was calculated using multivariable logistic regression model.

Results

High CHOL or TG prevalence was 41% with participants being mostly male (73%), ≥ 40 years (68%), with overweight (31%) or obesity (28%), and virally suppressed (62%). Compared with PWH < 40 years of age, PWH in their 40s, 50s, and ≥ 60s were 57%, 64%, and 62% more likely to have high CHOL or TG, respectively. Participants with overweight and obesity were 41% and 30% more likely to have high CHOL or TG than those with normal weight (BMI: 18.5– < 25), respectively.

Conclusion

Since high CHOL and TG are modifiable CVD risk factors, increased education and lifestyle modification interventions are warranted to prevent the development of high CHOL or TG among PWH.

Insulin resistance in people living with HIV is associated with exposure to thymidine analogues and/or didanosine and prior immunodeficiency

Background

As people living with HIV (PLWH) are growing older, there is increased incidence of metabolic diseases, including type 2 diabetes mellitus, for which insulin resistance is a key determinant. In this study, we aimed to investigate risk factors associated with insulin resistance in PLWH.

Methods

We included well-treated PLWH without hepatitis co-infection, and with available fasting serum insulin and plasma glucose (n = 643) from the Copenhagen Comorbidity in HIV Infection Study. Insulin resistance was calculated using the homeostasis model assessment of insulin resistance (HOMA-IR). We investigated the association between risk factors and high HOMA-IR in a logistic regression model adjusted for age, sex, abdominal obesity, smoking status, and origin. When including use of thymidine analogues and/or didanosine in the model, we also adjusted for time with HIV.

Results

Median (IQR) age of PLWH was 52 years (46–61), and 87% (n = 557) were male. Median (IQR) HOMA-IR was 1.86 (1.23–3.14) mmol/L × mU/L. Risk factors significantly associated with high HOMA-IR included older age, BMI ≥ 25, abdominal obesity, waist circumference, use of thymidine analogues and/or didanosine, time with HIV, and CD4⁺ nadir < 200 cells/µL.

Conclusions

Insulin resistance in PLWH is associated with both use of thymidine analogues and/or didanosine and prior immunodeficiency suggesting that increased attention on blood glucose in these patients could be beneficial.

When therapeutic drugs lead to diabetes

Drug-induced diabetes mellitus is a growing problem in clinical practice. New, potent medications contribute to this problem in a population already at high risk of developing glucose disturbances because of poor lifestyle habits and high prevalence of being overweight/obese. The present review focuses on four important pharmacological classes: glucocorticoids; antipsychotics, especially second generation; antiretroviral therapies, which revolutionised the management of individuals with HIV; and immune checkpoint inhibitors, recently used for the immunotherapy of cancer. For each class, the prevalence of drug-induced diabetes will be evaluated, the most common clinical presentations will be described, the underlying mechanisms leading to hyperglycaemia will be briefly analysed, and some recommendations for appropriate monitoring and management will be proposed.

Sex differences in type 2 diabetes mellitus prevalence among persons with HIV

OBJECTIVE

To examine whether type 2 diabetes mellitus (T2DM) is more common among women with HIV (WWH) than men with HIV (MWH).

DESIGN

A cross-sectional analysis of a demographically heterogenous population-based sample of more than 64 million patients in the United States.

METHODS

Using the Explorys (IBM) database, compare the prevalence of T2DM among men and women without HIV and influence of HIV on T2DM by sex controlling for confounding factors.

RESULTS

From 19 182 775 persons included in the study, 39 485 were with HIV. Rates of obesity was higher among WWH than MWH (58 vs. 35%). Prevalence of T2DM among WWH was 23% compared with 16% among MWH (P < 0.001). In sex-stratified adjusted analysis, WWH had 1.31 [95% confidence interval (CI), 1.24-1.38] times the odds of having T2DM than women without HIV. Women with HIV was associated with T2DM across all demographic subgroups. In contrast, no association between HIV and T2DM was observed among men (OR 1.01; 95% CI 0.98-1.05).

CONCLUSION

These data suggest that HIV confers a sex-specific increase in odds of T2DM among women but not men.

Associations of HIV and Depression with Incident Diabetes Mellitus: Veterans Aging Cohort Study

BACKGROUND

Persons with HIV (PWH) are at increasingly higher risk for metabolic complications, including diabetes mellitus (DM). Additionally, depression is highly prevalent among PWH and has been associated with increased risk for DM in the general population. However, the association of HIV and depression with incident DM has not been well established.

METHODS

Using the Veterans Aging Cohort Study (VACS), we selected adults with and without HIV who did not have DM at baseline. Prevalent depression was defined as having a Patient Health Questionnaire-9 (PHQ-9) score of ≥10. Incident DM was identified using validated Kelly's criteria. Basic clinical and demographic characteristics were collected, and cox proportional hazards regression models were run to test the association between depression and incident DM stratified by HIV serostatus.

RESULTS

A total of 5,722 participants were analyzed, 2,886 (53%) had HIV and 1,124 (20%) had depression at baseline. 1,235 (22%) participants developed incident DM during follow-up, with 26% of HIV-negative participants developing DM compared to 17% of participants with HIV. Depression was significantly associated with increased risk of incident DM among HIV-negative participants (adjusted HR [aHR] = 1.31; p-value 0.003), but not among participants with HIV (aHR 1.09; p-value 0.44). However, among participants with HIV with baseline viral load < 500 copies/mL, we noted a stronger association between depression and incident DM.

CONCLUSIONS

Incident DM in the VACS cohort is significantly higher for HIV-negative participants compared to veterans with HIV. A significant association between depression and incident DM was noted among HIV-negative participants but not among those with HIV.

Diabetes mellitus among adults on highly active anti-retroviral therapy and its associated factors in Ethiopia: Systematic review and meta-analysis

BACKGROUND

Diabetes mellitus occurs as a comorbid illness among people living with HIV and, in particular those on Highly Active Anti-retroviral therapies (HAART). Previous studies have documented the prevalence of diabetes mellitus among adults on HAART; however, there is lack of comprehensive estimation. Hence, this study was aimed to estimate the pooled prevalence and associated factors of diabetes mellitus among adults on HAART in Ethiopia.

METHODS

Primary studies were exhaustively searched using Cochrane, PubMed, Google Scholar, Scopus and Web of science databases until February 2021. Eligible studies were selected and critically appraised for quality using the Joanna Briggs Institute (JBI) quality appraisal checklist. The required data were extracted and exported to Stata version 16 for meta-analysis. The overall prevalence of diabetes mellitus among adults on HAART was estimated using a weighted inverse random effect model. Sensitivity and sub-group analysis were conducted for evidence of heterogeneity. Trim and fill analysis was performed after Egger's test and funnel plot were indicating the presence of publication bias.

RESULTS

A total of 17 studies with 6,052 subjects on HAART were included. The pooled prevalence of diabetes mellitus among patients on HAART was 16.04% [95% Confidence Interval (CI); 11.6, 20.92]. Abnormal High Density Lipoprotein Cholesterol (HDL-C) [Adjusted Odd Ratio (AOR) = 4.68, 95% CI; 2.54, 6.82], Body Mass Index (BMI) ≥ 25 kg/m² [AOR = 7.41, 95% CI; 2.75, 12.08], ≥6 years ART [AOR = 8.14, 95% CI; 5.85, 30.43], hypertension [AOR = 3.29, 95% CI; 2.13, 4.45], age 35-44 years [AOR = 6.28; 95% CI; 4.20, 8.37, BMI ≥ 30 kg/m² [AOR = 7.81, 95% CI; 4.97, 10.64], educational status above diploma [AOR = 6.42, 95% CI; 1.28, 11.57] and age 45-55 years [AOR = 4.46, 95% CI; 2.81, 6.10] were positively associated with diabetes mellitus comorbidity among adults on HAART.

CONCLUSION

The higher prevalence of diabetes mellitus was observed for adults on HAART. HDL-C, duration of ART, hypertension, overweight, obesity, age and educational status of participants increases the prevalence of diabetes mellitus. The study highlights the importance of timely screening of HDL-C level, blood pressure and BMI for adults on HAART.

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.

The shifting picture of HIV treatment, comorbidity and substance use among US MSM living with HIV

OBJECTIVES

People living with HIV (PLWH) have increased risk of chronic disease and poor mental health. We aimed to explore HIV disease indicators, comorbidity, and risk behavior of recent antiretroviral therapy (ART) initiators to inform current needs of PLWH.

METHODS

Men who have sex with men (MSM) in the Multicenter AIDS Cohort Study (MACS) who initiated ART between 2010 and 2018 (recent initiators) were compared with age-, race- and geographic location-matched men who initiated ART during 2000-2009 (early initiators). Measures of HIV disease, behavior, comorbidity and mental health were collected prospectively every 6 months using standardized forms.

RESULTS

Recent initiators had higher current CD4 (median CD4 451 vs. 307 cells/μL, P < 0.0001) and nadir CD4 (451 vs. 300 cells/μL, P < 0.0001) than earlier initiators. The proportion achieving viral suppression within a year of starting ART was significantly higher in recent compared with earlier initiators (92% vs. 74%, P < 0.0001). Median [interquartile range (IQR)] time from HIV diagnosis to ART initiation was 5.4 (1.7-23.1) months in recent initiators. Comorbidity prevalence was high in recent initiators, including obesity (24%), hypertension (25%) and kidney disease (15%). Substance use continues to be common, including cigarette use (40%), daily alcohol use (88%) and marijuana use (46%).

CONCLUSIONS

Improvements in getting individuals onto ART at an early stage have led to substantially higher CD4 cell counts at initiation. However, the high burden of comorbidity, substance use and poor mental health affecting MSM living with HIV in the US underscore ongoing challenges and our need to adapt and coordinate care.

The Role of HIV Infection in the Pathophysiology of Gestational Diabetes Mellitus and Hypertensive Disorders of Pregnancy

Purpose of the Review: The main objective of this study is to investigate mechanisms associated with gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) in HIV infected pregnant women by looking how placental hormones such as (progesterone and prolactin) and basic haemostatic parameters are regulated in HIV infected pregnancies.

Recent Findings: HIV/AIDS are a major global obstetric health burden that lead to increased rate of morbidity and mortality. HIV/AIDS has been associated with the pathophysiology of GDM and HDP. Increased risk of GDM due to highly active antiretroviral therapy (HAART) usage has been reported in HIV infected pregnancies, which causes insulin resistance in both pregnant and non-pregnant individuals. HAART is a medication used for lowering maternal antepartum viral load and pre-exposure and post-exposure prophylaxis of the infant. In pregnant women, HAART induces diabetogenic effect by causing dysregulation of placental hormones such as (progesterone and prolactin) and predispose HIV infected women to GDM. In addition to HIV/AIDS and GDM, Studies have indicated that HIV infection causes haemostatic abnormalities such as hematological disorder, deregulated haematopoiesis process and the coagulation process which results in HDP.

Summary: This study will help on improving therapeutic management and understanding of the pathophysiology of GDM and HDP in the absence as well as in the presence of HIV infection by reviewing studies reporting on these mechanism.

Incidence of diabetes mellitus among people living with and without HIV in British Columbia, Canada between 2001 and 2013: a longitudinal population-based cohort study

INTRODUCTION

People living with HIV (PLHIV) are increasingly at risk of age-related comorbidities such as diabetes mellitus (DM). While DM is associated with elevated mortality and morbidity, understanding of DM among PLHIV is limited. We assessed the incidence of DM among people living with and without HIV in British Columbia (BC), Canada, during 2001-2013.

METHODS

We used longitudinal data from a population-based cohort study linking clinical data and administrative health data. We included PLHIV who were antiretroviral therapy (ART) naïve at baseline, and 1:5 age-sex-matched persons without HIV. All participants had ≥5 years of historic data pre-baseline and ≥1 year(s) of follow-up. DM was identified using the BC Ministry of Health's definitions applied to hospitalisation, physician billing and drug dispensation datasets. Incident DM was identified using a 5-year run-in period. In addition to unadjusted incidence rates (IRs), we estimated adjusted incidence rate ratios (IRR) using Poisson regression and assessed annual trends in DM IRs per 1000 person years (PYs) between 2001 and 2013.

RESULTS

A total of 129 PLHIV and 636 individuals without HIV developed DM over 17 529 PYs and 88,672 PYs, respectively. The unadjusted IRs of DM per 1000 PYs were 7.4 (95% CI 6.2 to 8.8) among PLHIV and 7.2 (95% CI 6.6 to 7.8) for individuals without HIV. After adjustment for confounding, HIV serostatus was not associated with DM incidence (adjusted IRR: 1.03, 95% CI 0.83 to 1.27). DM incidence did not increase over time among PLHIV (Kendall trend test: p=0.9369), but it increased among persons without HIV between 2001 and 2013 (p=0.0136).

CONCLUSIONS

After adjustment, HIV serostatus was not associated with incidence of DM, between 2001 and 2013. Future studies should investigate the impact of ART on mitigating the potential risk of DM among PLHIV.

Prevalence and risk factors of type II diabetes mellitus among people living with HIV in Texas

This study aimed to determine the prevalence and risk factors associated with type II diabetes mellitus (T2DM) among people living with HIV (PLWH). Cross-sectional data of 989 PLWH in Texas obtained from the 2015-2017 Texas and Houston Medical Monitoring Project were examined. T2DM was identified by formal medical chart diagnosis, insulin/oral hypoglycemic prescriptions, or most recent fasting blood glucose ≥126 mg/dL. T2DM adjusted prevalence ratios and 95% confidence intervals (CIs) were estimated using multiple logistic regression. Participants were mostly male (72%), ≥40 years (68%), overweight (31%) or obese (28%) and virally suppressed (62%). T2DM prevalence was 15% with variations by age, body mass index, education and health insurance (p < 0.05 for all). Compared to PLWH ≥60 years, 18-39-year-olds had significantly lower likelihood of T2DM (p < 0.001). Overweight and obese PLWH were 2.11 (95% CI: 1.23-3.63) and 3.89 times (95% CI: 2.30-6.56) more likely to have T2DM compared to normal weight PLWH. Over 1 in 6 PLWH in Texas had T2DM, with age and BMI as significant predictors. Since DM is a risk factor for cardiovascular disease and PLWH are living longer, increased education and lifestyle modification interventions are warranted to prevent T2DM development among PLWH.

Mechanisms and primary prevention of atherosclerotic cardiovascular disease among people living with HIV

PURPOSE OF REVIEW

To highlight mechanisms of elevated risk of atherosclerotic cardiovascular disease (ASCVD) among people living with HIV (PLWH), discuss therapeutic strategies, and opportunities for primary prevention.

RECENT FINDINGS

HIV-associated ASCVD risk is likely multifactorial and due to HIV-specific factors and traditional risk factors even in the setting of treated and suppressed HIV disease. Although a growing body of evidence suggests that inflammation and immune activation are key drivers of atherogenesis, therapies designed to lower inflammation including colchicine and low-dose methotrexate have not improved secondary cardiovascular endpoints among PLWH. Statins continue to be the mainstay of management of hyperlipidemia in HIV, but the impact of newer lipid therapies including proprotein convertase subtilisin/kexin type 9 inhibitors on ASCVD risk among PLWH is under investigation. Aside from the factors mentioned above, healthcare disparities are particularly prominent among PLWH and thus likely contribute to increased ASCVD risk.

SUMMARY

Our understanding of mechanisms of elevated ASCVD risk in HIV continues to evolve, and the optimal treatment for CVD in HIV aside from targeting traditional risk factors remains unknown. Future studies including novel therapies to lower inflammation, control of risk factors, and implementation science are needed to ascertain optimal ways to treat and prevent ASCVD among PLWH.

Clinical and angiographical features of first episode of acute coronary syndrome in patients with human immunodeficiency virus infection

BACKGROUND

Patients affected by the human immunodeficiency virus (HIV) show an increased risk of myocardial infarction. Clinical and angiographic features of HIV positive (HIV+) patients presenting with the first episode of an acute coronary syndrome (ACS) are not well defined in previous studies.

OBJECTIVE

To demonstrate that HIV + patients with acute coronary syndrome had different features than non-HIV patients.

METHODS

We identified 48 HIV + patients without previous cardiovascular events admitted to our Emergency Department with ACS diagnosis between 2012 and 2020. Clinical and angiographic characteristics were compared with a control group of 48 non-HIV consecutive patients affected by ACS as first episode.

RESULTS

HIV + patients were most frequently men (87.5% vs 62.5%, p = 0.009) and younger about a decade (mean age 53.8 ± 8.2 vs 63.7 ± 11.9 years old, p < 0.0001); statistically significant hypertriglyceridemia has been found in the HIV group (178,6 ± 59,8 mg/dl vs 142,7 ± 63,7 mg/dl, p = 0.005). HIV(+) patients had a higher rate of anterior ST-elevation myocardial infarction (STEMI) (65% vs 33%, p = 0.03) and significant lesions on left anterior descending (LAD) coronary artery (83% vs 58% p = 0.01).

CONCLUSIONS

HIV + patients with the first episode of ACS are generally young men with higher triglycerides and most frequently presenting with anterior STEMI and LAD involvement. The strict control of risk factors and a program for the early identification of coronary artery disease are strongly recommended in this subset of patients.

The burden of non-communicable diseases and mortality in people living with HIV (PLHIV) in the pre-, early- and late-HAART era

Objectives

To estimate the burden of non‐communicable diseases (NCDs) and mortality among PLHIV in the pre‐, early‐ and late‐HAART (highly active antiretroviral therapy) era.

Methods

We conducted a cohort study using population‐based Danish medical registries including all adult HIV‐infected residents of the Central Denmark Region during 1985–2017. For each HIV patient, we selected 10 comparisons from the background population matched by age, sex and municipality of residence. Based on hospital‐related diagnoses we estimated the prevalence and incidence of specific NCD at diagnosis and at 5 and 10 years.

Results

We identified 1043 PLHIV and 10 430 matched comparisons. PLHIV had lower socioeconomic status and more were born outside western Europe. At HIV diagnosis, 21.9% of PHLIV vs. 18.2% of non‐HIV individuals had at least one NCD, increasing to 42.2% vs. 25.9% after 10 years. PLHIV had higher prevalence and cumulative incidence of alcohol abuse, chronic obstructive pulmonary disease (COPD), ischaemic heart disease, mental disorders, renal and liver disease, but no increased risk of diabetes mellitus. Only PLHIV in the age groups 41–50 and > 51 years had an increased incidence of osteoporosis. From the pre‐ to the late‐HAART era, 10‐year mortality among PLHIV decreased from 45.5% to 9.4% but continued at more than twice that of uninfected comparisons. However, in the late‐HAART era, the mortality of PLHIV who were alive 2 years after HIV diagnosis was approaching that of comparisons.

Conclusions

Even in the late‐HAART era, PLHIV have an excess mortality, which may be attributable to several NCDs being more prevalent among PLHIV. The prevalence rates of ischaemic heart disease, diabetes, osteoporosis and renal disease tend to increase over calendar time. Therefore, improvement of survival and quality of life of PLHIV neets strategies to reduce the risk of developing NCDs, including avoiding toxic antiretroviral therapy and lifestyle changes.

Prevalence and predictors of diabetes mellitus among persons living with HIV: a retrospective cohort study conducted in 4 public healthcare facilities in KwaZulu-Natal

Background

Diabetes mellitus is a chronic non-infectious medical condition which is evident by raised levels of glucose in the blood, because the body cannot produce any or enough of the hormone insulin or use insulin effectively. Diabetes, if not well managed leads to complications such as neuropathy, retinopathy, nephropathy which can be fatal. Some of the factors that predisposes to diabetes include older age, higher body mass index, heredity and hypertension.

With the availability of HAART for managing HIV/AIDS infection, life span of persons living with HIV (PLWHIV) has increased significantly. With increased longevity, the aging population of PLWHIV also face chronic diseases such as diabetes in addition to HIV. The burden of both HIV and diabetes is high in South Africa, particularly in KwaZulu-Natal. Nevertheless, the prevalence of diabetes among PLWHIV in KwaZulu-Natal and its predictors is not well understood. Therefore, this study was conducted to determine the prevalence, predictors of diabetes and the outcome of managing diabetes among PLWHIV.

Methods

This retrospective cohort study was conducted in four public health care facilities in KwaZulu-Natal with a total sample size of 1203 after ethical approval and informed consent were obtained. A pretested questionnaire and hospital patient charts were used to collect data. SPSS version 26 was used to analyze the data using descriptive statistics and logistic regression.

Results

The prevalence of diabetes among PLWHIV was 9%. Just over 47% of those who had diabetes, had uncontrolled blood sugar, with a mean fasting blood sugar (FBS) of 11.7 mmol/L. The predictors of diabetes among PLWHIV were male gender and older age. Male PLWHIV had 65% less chances of having diabetes and those who were between the ages of 18 and 48 years were 88% less probable to have diabetes compared to those who were older than 48 years.

Conclusion

Public sector health care facilities in KwaZulu-Natal need to do much more to manage diabetes in PLWHIV in order to prevent diabetic complications and possible negative impact on the outcome of HIV management.

The pharmacological management of cardiovascular disease in people living with HIV (PLWH)

ABSTARCTIntroduction: Cardiovascular disease (CVD) continues to be an essential cause of morbidity and mortality among people living with human immunodeficiency virus infection (PLWH). Since the bulk of cardiovascular risk (CVR) factors are shared between PLWH and the general population, prevention and treatment strategies are similar. However, there are CVR factors particular to PLWH, which need separate consideration. These factors are those HIV-dependent, those related to HIV-derived consequences, and combination antiretroviral therapy (cART)-dependent.Areas covered: In this review, the authors discuss the management of CVD in PLWH, with a special interest in pharmacological treatment and drug-drug interactions with cART.Expert opinion: In recent years, we have witnessed a decreased CVD morbidity and mortality in PLWH, which probably reflects an improvement in the management of CVR factors and CVD in these patients, partially thanks to new developments in antiretroviral therapy. Therefore, although there is still room for improvement, at present, the old desideratum of equaling PLWH and the general population in terms of CVD incidence and prognosis is a little closer.

Profile of elderly patients receiving antiretroviral therapy at Newlands Clinic in 2020: A cross-sectional study

Background

People living with HIV (PLWH) face new challenges such as accelerated ageing and higher rates of comorbidities including cardiovascular, renal and metabolic diseases as they age.

Objectives

To profile the demographic and clinical characteristics of elderly patients receiving HIV care at Newlands Clinic (NC), Harare, Zimbabwe, as of 01 October 2019.

Methods

A cross-sectional analysis was conducted using clinic data. All patients who were 50 years and older on 01 October 2019 were enrolled. Descriptive statistics (medians, interquartile ranges [IQRs] and proportions) were used to describe patient demographic and clinical characteristics.

Results

Out of 6543 patients undergoing care at NC, 1688 (25.8%) were older than 50 years. The median duration of antiretroviral therapy (ART) was 10.9 years (IQR: 7.1–13). Over 90% of all patients had an HIV viral load below 50 copies/mL. Women were more likely than men to be overweight and obese (32% and 25% vs. 18% and 7%, respectively). Hypertension (41.2%), arthritis (19.9%) and chronic kidney disease (11.6%) were common comorbidities differently distributed based on sex. The most common malignancy diagnosed in women was cervical intra-epithelial neoplasia (68% of cancer burden in women) and Kaposi sarcoma was the leading malignancy in men (41% of cancer burden in men). Nearly 20% of patients had at least two chronic non-communicable comorbidities and 5.6% had at least three.

Conclusion

A high burden of comorbidities was observed amongst HIV-positive elderly patients receiving ART. Age-appropriate monitoring protocols must be developed to ensure optimum quality of care for elderly HIV-positive individuals.

Management of infection among Medicare beneficiaries with HIV/AIDS: risk of diabetes with protease inhibitors and associated racial disparities using big data approach

Association between protease inhibitors (PI) and Type II diabetes mellitus (T2DM) in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patients is largely debated. This study examined the odds of developing T2DM among HIV/AIDS Medicare beneficiaries treated with PI and possible racial disparities in the odds. We performed a nested casecontrol study of Medicare database 2013-2017. We included HIV/AIDS positive beneficiaries who were enrolled continuously in Medicare Part A/B with no previous history of T2DM. PI-users were matched to non-PI users and non-anti-retroviral therapies (ART) users using a1:1 greedy propensity score (PS) matching . Multivariablee logistic regressions were performed to assess the odds of developing T2DM. The analysis included 2,353 HIV/AIDS beneficiaries. Matched samples were generated for PI vs. non-PI groups (n = 484) and PI vs. non-ART groups (n = 490). Compared to the non-PI group, the odds of developing T2DM were higher in PI-users (AOR: 1.76; 95% CI: 1.17-2.64), in Caucasian PI-users (AOR: 1.81; 95% CI: 1.02-3.22) and in African-American PI-users (AOR: 1.86; 95% CI: 1.03-3.36). Compared to the non-ART group, the odds of developing T2DM were higher in PI-users (AOR: 1.87; 95% CI: 1.25-2.81), in Caucasian PI-users (AOR: 1.96; 95% CI: 1.14-3.39) and in African-American PI-users (AOR: 2.05; 95% CI: 1.03-4.09). The use of PI is associated with higher odds of T2DM; odds were higher among African-Americans than Caucasians.

Prevalence of obesity and disturbances in glucose homeostasis in HIV-infected subjects and general population - missed diagnoses of diabetes?

Objectives

Comparative data on glucose disorders using fasting blood samples between people living with HIV (PLWH) and the general population are lacking. The objective of this study was to compare the prevalence and risk factors of obesity and disturbances in glucose homeostasis between PLWH treated with modern antiretroviral therapy and the general population.

Methods

Adjusted prevalence of obesity, features of insulin resistance (triglyceride:high‐density lipoprotein cholesterol ratio and alanine aminotransferase), impaired fasting glucose (IFG), diabetes mellitus (DM) and combined dysglycaemia (presence of IFG or DM) were determined using fasting blood samples among 1041 PLWH and 7047 subjects representing the general population.

Results

People living with HIV had a lower prevalence of obesity [18.2%, 95% confidence interval (CI): 15.1–21.2 vs. 23.9%, 95% CI: 22.4–25.4], but a higher prevalence of insulin resistance and IFG (20.0%, 95% CI: 16.6–23.4 vs. 9.8%, 95% CI: 8.7–10.8) than the general population. Fasting glucose concentration was higher, but glycated haemoglobin (HbA1c) was lower, among PLWH. Prevalence of dysglycaemia for a given body mass index (BMI) was higher in PLWH than in the general population. The prevalence of DM did not differ between PLWH (13.2%, 95% CI: 10.2–15.9) and the general population (14.5%, 95% CI: 13.6–15.4).

Conclusions

The prevalence of obesity was lower, but the risk of dysglycaemia for a given BMI was significantly higher, among PLWH, highlighting the importance of prevention and treatment of obesity among HIV‐infected subjects. Regardless of the increased prevalence of insulin resistance and IFG, DM was surprisingly not more common among PLWH, raising concern about the under‐diagnosis of DM, possibly due to low sensitivity of HbA1c in this patient population.

HIV Care Among Elderly Population: Systematic Review and Meta-Analysis

Elderly people living with HIV are increasing. At present in the United States, nearly half of newly diagnosed HIV-infected people are aged >50 years. Diagnosis and treatment of HIV-infected elderly patients tends to be delayed by several health care factors as several life-threatening diseases are common in elderly people. This study aimed to find the pooled HIV prevalence in elderly population and the present situation of continuum care for the elderly HIV patients through systematic review and meta-analysis. All previously published articles from 2000 to 2018 are retrieved using MEDLINE, PUBMED, Cochrane Library, EMBASE, and Google Scholar. DerSimonian and Laird Random Effects model are used to critically appraise articles. STATA 13.0 is used to perform the meta-analysis and quantum-geographic information system (Q-GIS) is used to prepare desired map. I² statistics has been used to test heterogeneity and publication biases. Results have been presented using forest plots. A total of 28 studies are included in this meta-analysis. Present analysis revealed pooled prevalence of HIV in elderly population as 15.79% with a lower rate of viral suppression as 11.524% (95% confidence interval, CI: 11.199-11.855), where a moderate number 38.643% (95% CI: 38.289-38.997) of elderly patients received antiretroviral therapy (ART) globally. The ART retention rate was 12.769% (95% CI: 12.540-13.001) with 6.15% (95% CI: 6.089-6.212) mortality. Despite successful administration of ART in developing part of the world that have relatively higher retention rates among HIV-infected elderly patients only a small percentage are virally suppressed, largely due to elderly drugs interact with ART and several comorbidities reduce the life span of the elderly people.

Comorbidity Medications Are Dispensed to More People Receiving Antiretroviral Therapy for HIV Compared with the General Population in Australia

Medical comorbidities occur in more persons with HIV than without HIV. We used a nationally representative 10% sample of 2016 Pharmaceutical Benefits Scheme (PBS) dispensing data to compare the proportions of antiretroviral therapy (ART)-purchasing and non-ART-purchasing patients who also purchased prescriptions for medical comorbidities. Each patient who purchased ART was compared with two gender- and age group-matched patients who did not purchase ART in the same year. We calculated the proportions of patients who also purchased coprescriptions used for hypertension, dyslipidemia, diabetes, cancer, low bone mineral density, and mental health, defined using PBS medication coding categories, and the resulting odds ratios. A total of 1,973 ART-purchasing patients in our sample were matched to 3,946 non-ART-purchasing patients. Compared with non-ART-purchasing patients, a greater proportion of ART-purchasing patients also purchased medications for dyslipidemia (19.8% vs. 16.6%; p-value = .003), low bone mineral density (1.5% vs. 0.8%; p-value = .02), and mental health (29.1% vs. 15.3%; p-value < .0001); a lower proportion purchased diabetes medications (4.8% vs. 6.5%; p-value = .009). These differences remained when our analysis was restricted to persons >55 years of age. Rates of multimorbidity (dispensed ≥2 medications for chronic conditions) were also higher among ART-purchasing patients (19.0% vs. 15.9%; p-value = .003). Using a nationally representative sample of prescription dispensing data, we found that higher proportions of ART-purchasing patients purchased coprescriptions for common comorbidities compared with non-ART-purchasing patients. Our finding that ART-purchasing patients purchased fewer diabetes medications is surprising, but may reflect differences in population characteristics between our two groups.

Cardiovascular risk factors in HIV infected individuals: Comparison with general adult control population in Greece

Background

Although combined antiretroviral therapy has substantially improved the prognosis of people living with HIV (PLHIV), mortality remains higher compared to the general population, mainly due to higher prevalence of non-HIV-related comorbidities, including cardiovascular diseases (CVD). We assessed the prevalence of CVD risk and its contributing factors in adult PLHIV versus general population controls in Greece.

Settings

Cross-sectional comparison of PLHIV (Athens-Multicenter-AIDS-Cohort-Study; AMACS) versus general population controls (National health examination survey; EMENO).

Methods

All HIV-infected adults with ≥1 measurement of interest (blood pressure, lipids, glucose, weight, height) between 2012–2014 and all EMENO participants (2014–2016) were included. Ten-year total CVD risk was estimated using the Framingham (FRS) or the Systematic Coronary Risk Evaluation (SCORE) equations.

Results

5839 PLHIV (median age:41.6 years, 85.4% males) and 4820 controls (median age:48 years, 48.4% males) were included. Adjusting for age, sex and origin, PLHIV were more likely to be current smokers (adjusted OR:1.53 [95% CI:1.35–1.74]) and dyslipidemic (aOR:1.18; [1.04–1.34]), less likely to be obese (aOR:0.44 [0.38–0.52], with no differences in hypertension, diabetes or high (≥20%) FRS but with greater odds of high (≥5%) SCORE (aOR:1.55 [1.05–2.30]). Further adjustment for educational level, anti-HCV positivity and BMI showed higher prevalence of hypertension in PLHIV.

Conclusions

Despite the relative absence of obesity, PLHIV have higher prevalence of traditional CVD risk factors and higher risk of fatal CVD compared to general population. Regular screening and early management of CVD risk factors in PLHIV should be of high priority for CVD prevention.

Comorbidity of HIV, hypertension, and diabetes and associated factors among people receiving antiretroviral therapy in Bahir Dar city, Ethiopia

Background:

People living with human immunodeficiency virus (HIV) are facing an increased burden of noncommunicable diseases (NCDs) comorbidity. There is, however, paucity of information on the magnitude of HIV-NCDs comorbidity, its associated factors, and how the health system is responding to the double burden in Ethiopia.

Objective:

To determine the magnitude of comorbidity between HIV and hypertension or diabetes and associated factors among HIV-positive adults receiving antiretroviral therapy (ART) in Bahir Dar city, Ethiopia.

Methods:

A facility-based cross-sectional study was conducted among 560 randomly selected HIV-positive adults taking ART. Data were collected using a structured questionnaire and analyzed using SPSS version 23. Descriptive statistics were used to describe the data. A logistic regression model was fit to identify associated factors with comorbidity of HIV and NCDs.

Results:

The magnitude of comorbidity was 19.6% (95% confidence interval (CI): 16.0–23.0). Being older (55 and above years) adjusted odds ratio (AOR: 8.5; 95% CI: 3.2–15.1), taking second-line ART regimen containing tenofovir (AOR: 2.7; 95% CI: 1.3–5.6), and increased body mass index (BMI) ≥25 (AOR: 2.7; 95% CI: 1.2–6.5) were the factors associated with comorbidity. Participants reported that they were not managed in an integrated and coordinated manner.

Conclusions:

The magnitude of comorbidity among adults was high in the study area. Being older, second-line ART regimen and high BMI ≥25 increased the odds of having NCDs among HIV-positive adults. Targeted screening for the incidences of NCDs, addressing modifiable risk factors, and providing integrated care would help to improve the quality of life comorbid patients.

Prevention of cardiovascular disease among people living with HIV in sub-Saharan Africa

As longevity has increased for people living with HIV (PLWH) in the United States and Europe, there has been a concomitant increase in the prevalence of cardiovascular disease (CVD) risk factors and morbidity in this population. Whereas the availability of HIV antiretroviral therapy has resulted in dramatic increases in life expectancy in sub-Saharan Africa (SSA), where over two thirds of PLWH reside, if and how these trends impact the epidemiology of CVD is less clear. In this review, we describe the current state of the science on how both HIV and its treatment impact CVD risk factors and outcomes among PLWH in sub-Saharan Africa, including regional factors (unique to SSA) likely to differentiate these relationships from the global North. We then outline how current regional guidelines address CVD prevention among PLWH and which clinical and structural interventions are best poised to confront the co-epidemics of HIV and CVD in the region. We conclude with a discussion of key research gaps that need to be addressed to optimally develop an actionable public health response.

HIV infection and coronary heart disease: mechanisms and management

Antiretroviral therapy has largely transformed HIV infection into a chronic disease condition. As such, physicians and other providers caring for individuals living with HIV infection need to be aware of the potential cardiovascular complications of HIV infection and the nuances of how HIV infection increases the risk of cardiovascular diseases, including acute myocardial infarction, stroke, peripheral artery disease, heart failure and sudden cardiac death, as well as how to select available therapies to reduce this risk. In this Review, we discuss the epidemiology and clinical features of cardiovascular disease, with a focus on coronary heart disease, in the setting of HIV infection, which includes a substantially increased risk of myocardial infarction even when the HIV infection is well controlled. We also discuss the mechanisms underlying HIV-associated atherosclerotic cardiovascular disease, such as the high rates of traditional cardiovascular risk factors in patients with HIV infection and HIV-related factors, including the use of antiretroviral therapy and chronic inflammation in the setting of effectively treated HIV infection. Finally, we highlight available therapeutic strategies, as well as approaches under investigation, to reduce the risk of cardiovascular disease and lower inflammation in patients with HIV infection.

Metabolic Syndrome Among People Living with HIV Receiving Medical Care in Southern United States: Prevalence and Risk Factors

Using representative data among 1861 in care people living with HIV (PLWH) in four southern states (Texas, Mississippi, Florida, and Georgia) from the 2013-2014 Medical Monitoring Project (MMP) survey, we estimated the prevalence and odds of metabolic syndrome (MetS) among various demographic and HIV related risk factors. Overall MetS prevalence was 34%, with our participants being mostly black (55%), male (72%), ≥ 50 years old (46%), and overweight or obese (60%) with undetectable viral loads (≤ 200 copies/ml, 69%), and were currently taking antiretroviral medication (98%). Compared to those who were ≥ 60 years, 18-39 year olds had a 79% (95% CI 0.13-0.33) lower odds of having MetS. Women were 2.24 times more likely to have MetS than men (95% CI 1.69-2.97). Age and sex were significant predictors of MetS. Since MetS is a combination of chronic disease risk factors, regular screening for MetS risk factors among aging PLWH is crucial.

Incidence of select chronic comorbidities among a population-based cohort of HIV-positive individuals receiving highly active antiretroviral therapy

Objective: To characterize the incidence of select chronic comorbidities in the era of modern (pre-integrase-inhibitor) highly active antiretroviral therapy (HAART) in British Columbia, Canada. Methods: We used data from the Comparative Outcomes And Service Utilization Trends (COAST) study, a population-based cohort study of people living with HIV (PLWH), to determine incidence rates of six key chronic diseases among PLWH receiving HAART in BC from 2000 to 2012. The selected diseases included cardiovascular disease (CVD), diabetes mellitus (DM), hypertension (HTN), asthma/chronic obstructive pulmonary disease (COPD), chronic kidney disease (CKD) and chronic liver disease (CLD) defined using ICD-9 and -10 codes. Disease incidence was determined by number of new cases per year. We used Poisson regression to measure trends in incidence rates. Results: The study sample (n = 10,210) was predominantly male (83%), white (72%) and younger than 50 years of age at HAART initiation (88%). Incidence rates of HTN per 1000 person-years (PY) increased significantly between 2000 and 2012, after adjusting for age, sex, baseline-weighted Charlson Comorbidity Index, CD4 cell count and viral load (p < .001); incidence rates of CKD and CLD decreased significantly over time (p < .001). Unadjusted incidence rates of DM increased over time (p < .01), but remained stable in the adjusted model. Incidence rate patterns for CVD and COPD/asthma were stable over the study period. Conclusions: Population-level increases in incidence rates for HTN, and decreases for CLD and CKD, were observed among PLWH on modern (pre-integrase-inhibitor) HAART from 2000 to 2012. Overall, the increasing incidence of several of these chronic comorbidities in our study suggests that further efforts are needed to maximize the potential for healthy aging among PLWH receiving modern (pre-integrase-inhibitor) HAART.

Diabetes mellitus among patients attending TB clinics in Dar es Salaam: a descriptive cross-sectional study

Background

A bi-directional interaction between diabetes mellitus and tuberculosis is well established and has been likened to that between HIV and TB. Whereas HIV screening is standard of care test in sub Saharan Africa TB programs, the same is not true for diabetes mellitus (DM). Sub Saharan Africa, a region with high TB infection rates, is going through an epidemiological transition with rapidly rising prevalence of diabetes.

We aimed at characterizing TB patients with DM in order to identify factors associated with TB-DM dual disease among patients attending TB clinics in Dar es Salaam.

Methods

A cross-sectional study was conducted between September 2016 and January 2017 among patients attending TB clinics in Dar es Salaam. We collected socio-demographic characteristics, anthropometric measurements and screened for diabetes by measuring fasting blood glucose that was followed by a 2 h postprandial glucose for participants with impaired fasting blood glucose. We examined for socio-demographic and clinical factors associated with diabetes using logistic regression analysis.

Results

Of the 660 enrolled participants with TB, 25 (3.8%) were on treatment for diabetes while 39 (6.1%) and 147 (23%) of the remaining 635 participants were ultimately diagnosed with DM and impaired fasting blood glucose respectively. The overall prevalence of DM was 9.7% (64/660). Independent risk factors for diabetes included: age > 44 years {OR 4.52, 95% CI: [1.28–15.89]}; family history of diabetes {OR 3.42, 95% [CI 1.88–6.21]}.

HIV sero-positive TB patients were less likely to have DM compared to those who were HIV sero-negative {OR 0.35, 95% CI [0.17–0.73]}.

Conclusions

Screening for diabetes should be advocated for TB patients aged above 44 years and/or with a family history of diabetes. HIV sero-negative TB patients were more likely to have DM compared to those who were HIV sero-positive. Further studies are needed to confirm this observation and the underlying factors.

HIV infection and lipids

PURPOSE OF REVIEW

We comment on the role of dyslipidaemia in cardiovascular disease (CVD) in HIV-infected patients. We have discussed various risk factors, including traditional CVD risk factors, HIV-related risk factors and antiretroviral therapy (ART)-induced dyslipidaemia.

RECENT FINDINGS

HIV-infected individuals are prone to lipid and lipoprotein abnormalities as a result of the infection itself and the effect of ART. The older drugs used for the treatment of HIV were associated with an increased risk of these abnormalities. New therapies used to treat HIV are lipid friendly. Calculating CVD risk in the HIV population is complex due to the infection itself and the ART-related factors. The advancement in ART has helped to increase the life expectancy of HIV patients. As a result, a growing number of patients die of non-HIV related complications such as CVD, hepatic and renal disease. Outcome studies with intervention for dyslipidaemia in HIV are underway.

SUMMARY

The implications of the above findings suggest that all patients with HIV should undergo a CVD risk assessment before starting ART. Appropriate lipid-friendly ART regimen should be initiated along with intervention for associated CVD risk factors (e.g. lipids, hypertension and smoking).

Hyperglycemia and insulin function in antiretroviral treatment-naive HIV patients in Ethiopia: a potential new entity of diabetes in HIV?

BACKGROUND

Although diabetes is more common in HIV patients, the direct link between HIV and diabetes is unknown. Glucose abnormalities should be assessed among antiretroviral treatment (ART)-naive patients to reduce confounding by ART. We assessed diabetes status, insulin function and association with inflammation among Ethiopian ART-naive HIV patients.

METHODS

Among HIV patients initiating ART, we used glycosylated hemoglobin (HbA1c) and oral glucose tolerance test (OGTT) to define prediabetes and diabetes. Insulin during OGTT was determined to calculate insulin function, and C-reactive protein and α1-acid glycoprotein were used as same-day markers of inflammation.

RESULTS

Among 332 HIV patients, mean (SD) age was 32.9 (8.8) years, and 222 (66.9%) were women. None had known diabetes, but we found diabetes prevalence using OGTT and HbA1c to be 7.6 and 8.5%, respectively. C-reactive protein and α1-acid glycoprotein were positively associated with hyperglycemia and insulin deficiency, but not insulin resistance. We found poor correlation between traditional risk factors (age and anthropometry) and diabetes, but participants generally had low BMI and waist circumference.

CONCLUSION

ART-naive Ethiopian HIV patients had a high prevalence of prediabetes and diabetes, with a poor agreement between HbA1c and OGTT. Diabetes was associated with inflammation, but not with adiposity and age. Diabetes was linked to insulin deficiency, rather than insulin resistance, which may represent a different entity than type 1 and 2 diabetes. This has implications for choice of drugs, when managing diabetes in African HIV patients.

Metabolic complications affecting adipose tissue, lipid and glucose metabolism associated with HIV antiretroviral treatment

Introduction: Efficient antiretroviral-treatment (ART) generally allows control of HIV infection. However, persons-living-with-HIV (PLWH), when aging, present a high prevalence of metabolic diseases. Area covered: Altered adiposity, dyslipidemias, insulin resistance, diabetes, and their consequences are prevalent in PLWH and could be partly related to ART. Expert opinion: At first, personal and lifestyle factors are involved in the onset of these complications. The persistence of HIV in tissue reservoirs could synergize with some ART and enhance metabolic disorders. Altered fat repartition, diagnosed as lipodystrophy, has been related to first-generation nucleoside-reverse-transcriptase-inhibitors (NRTIs) (stavudine zidovudine) and some protease inhibitors (PIs). Recently, use of some integrase-inhibitors (INSTI) resulted in weight/fat gain, which represents a worrisome unresolved situation. Lipid parameters were affected by some first-generation NRTIs, non-NRTIs (efavirenz) but also PIs boosted by ritonavir, with increased total and LDL-cholesterol and triglycerides. Insulin resistance is common associated with abdominal obesity. Diabetes incidence, high with first-generation-ART (zidovudine, stavudine, didanosine, indinavir) has declined with contemporary ART close to that of the general population. Metabolic syndrome, a dysmetabolic situation with central obesity and insulin resistance, and liver steatosis are common in PLWH and could indirectly result from ART-associated fat gain and insulin resistance. All these dysmetabolic situations increase the atherogenic cardiovascular risk.

Human Immunodeficiency Virus Infection and the Endocrine System

In the current era of effective antiretroviral therapies (ARTs), human immunodeficiency virus (HIV) infection became a chronic disorder that requires long term follow-up. Among other medical issues, these patients may develop endocrine problems, specific to HIV infection and its treatment. The purpose of this review is to give an overview of common endocrine complications associated with HIV infection, and to propose diagnostic and therapeutic strategies. HIV can affect the endocrine system at several levels. Adrenal and gonadal dysfunction, osteoporosis with increased fracture risk, dyslipidemia with increased cardiovascular risk, are some of the endocrine disorders prevalent in HIV-infected patients that may negatively influence quality of life, and increase morbidity and mortality. While ARTs have dramatically increased life expectancy in the HIV-infected population, they are not devoid of adverse effects, including endocrine dysfunction. Physicians caring for HIV-infected patients should be knowledgeable and exercise a high index of suspicion for the diagnosis of endocrine abnormalities, and in particular be aware of those that can be life threatening. Endocrine evaluation should follow the same strategies as in the general population, including prevention, early detection, and treatment.

Noncommunicable disease burden among HIV patients in care: a national retrospective longitudinal analysis of HIV-treatment outcomes in Kenya, 2003-2013

BACKGROUND

Over the last decade, the Kenyan HIV treatment program has grown exponentially, with improved survival among people living with HIV (PLHIV). In the same period, noncommunicable diseases (NCDs) have become a leading contributor to disease burden. We sought to characterize the burden of four major NCDs (cardiovascular diseases, cancer, chronic respiratory diseases and diabetes mellitus) among adult PLHIV in Kenya.

METHODS

We conducted a nationally representative retrospective medical chart review of HIV-infected adults aged ≥15 years enrolled in HIV care in Kenya from October 1, 2003 through September 30, 2013. We estimated proportions of four NCD categories among PLHIV at enrollment into HIV care, and during subsequent HIV care visits. We compared proportions and assessed distributions of co-morbidities using the Chi-Square test. We calculated NCD incidence rates and their confidence intervals in assessing cofactors for developing NCDs.

RESULTS

We analyzed 3170 records of HIV-infected patients; 2115 (66.3%) were from women. Slightly over half (51.1%) of patient records were from PLHIVs aged above 35 years. Close to two-thirds (63.9%) of PLHIVs were on ART. Proportion of any documented NCD among PLHIV was 11.5% (95% confidence interval [CI] 9.3, 14.1), with elevated blood pressure as the most common NCD 343 (87.5%) among PLHIV with a diagnosed NCD. Despite this observation, only 17 (4.9%) patients had a corresponding documented diagnosis of hypertension in their medical record. Overall NCD incidence rates for men and women were (42.3 per 1000 person years [95% CI 35.8, 50.1] and 31.6 [95% CI 27.7, 36.1], respectively. Compared to women, the incidence rate ratio for men developing an NCD was 1.3 [95% CI 1.1, 1.7], p = 0.0082). No differences in NCD incidence rates were seen by marital or employment status. At one year of follow up 43.8% of PLHIV not on ART had been diagnosed with an NCD compared to 3.7% of patients on ART; at five years the proportions with a diagnosed NCD were 88.8 and 39.2% (p < 0.001), respectively.  CONCLUSIONS: PLHIV in Kenya have a high prevalence of NCD diagnoses. In the absence of systematic, effective screening, NCD burden is likely underestimated in this population. Systematic screening and treatment for NCDs using standard guidelines should be integrated into HIV care and treatment programs in sub-Saharan Africa.

Incidence and Risk Factors for Prediabetes and Diabetes Mellitus Among HIV-infected Adults on Antiretroviral Therapy: A Systematic Review and Meta-analysis

OBJECTIVE

To summarize evidence on the rates and drivers of progression from normoglycemia to prediabetes and/or diabetes mellitus (hereafter "diabetes") in antiretroviral treatment (ART)-exposed HIV-infected people.

METHODS

We searched EMBASE, PubMed, Web of Science, and Global Index Medicus to identify articles published from 1 January 2000 to 30 April 2017. A random-effects model produced a summary estimate of the incidence across studies and heterogeneity was assessed using Cochrane's Q statistic.

RESULTS

We included 44 studies, whose methodologic quality was high with only 10 (30%) medium-quality studies and none of low quality. There was substantial heterogeneity between studies in estimates of the incidence of diabetes and prediabetes. The pooled incidence rate of overt diabetes and prediabetes were 13.7 per 1,000 person-years of follow-up (95% CI = 13, 20; I = 98.1%) among 396,496 person-years and 125 per 1,000 person-years (95% CI = 0, 123; I = 99.4) among 1,532 person-years, respectively. The major risk factors for diabetes and prediabetes were aging, family history of diabetes, Black or Hispanic origin, overweight/obesity, central obesity, lipodystrophy/lipoatrophy, dyslipidemia, metabolic syndrome, increased baseline fasting glycemia, and certain ART regimens.

CONCLUSIONS

These data highlight the important and fast-increasing burden of diabetes and prediabetes among the ART-exposed HIV-infected population. More research is needed to better capture the interplay between prediabetes/diabetes and ART in HIV-infected patients, considering the increasing number of ART-exposed patients subsequent to the World Health Organization's recommendation of initiating ART at HIV infection diagnosis regardless of CD4 count and age.

Cardiovascular disease and diabetes in HIV-positive and HIV-negative gay and bisexual men over the age of 55 years in Australia: insights from the Australian Positive & Peers Longevity Evaluation Study

OBJECTIVES

As HIV-positive people age, diagnosis and management of comorbidities associated with ageing are of increasing concern. In this study, we aimed to compare the self-reported prevalences of heart disease, stroke, thrombosis and diabetes in older Australian HIV-positive and HIV-negative gay and bisexual men (GBM).

METHODS

We analysed data from the Australian Positive & Peers Longevity Evaluation Study (APPLES), a study of a prospectively recruited cross-sectional sample of 228 (51.1%) HIV-positive and 218 (48.9%) HIV-negative GBM, aged ≥ 55 years. Regression methods were used to assess the association of HIV status with self-reported comorbidities.

RESULTS

Of 446 patients, 389 [200 (51.4%) HIV-positive] reported their disease history. The reported prevalence of comorbidities was higher in the HIV-positive group than in the HIV-negative group: heart disease, 19.5 versus 12.2%; stroke, 7.5 versus 4.2%; thrombosis, 10.5 versus 4.2%; and diabetes, 15.0 versus 9.0%, respectively. In adjusted analyses, HIV-positive GBM had significantly increased odds of reporting heart disease [adjusted odds ratio (aOR) 1.99; P = 0.03] and thrombosis (aOR 2.87; P = 0.01). In our analysis, HIV status was not significantly associated with either age at diagnosis of heart disease (median 53 years for HIV-positive GBM versus 55 years for HIV-negative GBM; P = 0.64) or 5-year cardiovascular disease (CVD) risk estimated using the Framingham risk score.

CONCLUSIONS

HIV-positive GBM more commonly reported heart disease and thrombosis compared with their HIV-negative peers. These results further highlight the need to understand the impact of HIV on age-related comorbidities in GBM, to guide optimal screening and treatment strategies to reduce the risk of these comorbidities among the HIV-positive population.

Lipid Abnormalities in Persons Living With HIV Infection

Lipid abnormalities are prevalent among persons living with HIV infection and contribute to increasing the risk of cardiovascular events. Antiretroviral therapy (ART) is associated with lipid abnormalities, most commonly hypertriglyceridemia, but also increases in low-density lipoprotein cholesterol and total cholesterol. Different classes of ART, and different drugs within classes, have differing effects on lipid levels, but in general newer drugs have more favourable effects compared with older ones. Low-level inflammation and chronic immune activation act on lipids through a variety of mechanisms to make them more atherogenic. As a consequence, risk is higher than would be expected for any given cholesterol level. Clinical outcome trials of cholesterol-lowering therapies have not yet been completed in people living with HIV, so that treatment decisions depend on extrapolation from studies in uninfected populations. Traditional risk assessment tools underestimate cardiovascular risk in individuals with HIV. Statins are the mainstay of lipid-lowering drug treatment; however, drug-drug interactions with ART must be considered. Simvastatin and lovastatin are contraindicated in patients taking protease inhibitors, and the dose of atorvastatin and rosuvastatin should be limited to 40 mg and 10 mg/d with some ART combinations. Switching from older forms of ART to lipid-friendly newer ones is a useful strategy as long as virologic suppression is maintained, but adding a statin lowers low-density lipoprotein cholesterol more effectively. Studies indicate that lipid abnormalities are not treated as aggressively in individuals living with HIV as they are in uninfected people, making this an opportunity to improve care.

Metabolic risk factors in young adults infected with HIV since childhood compared with the general population

AIM

Metabolic risk factors are poorly documented for the first generation of young adults who have lived with HIV since childhood. We compared their metabolic profile with that of adults of same age from the general population.

METHODS

We conducted a cross-sectional analysis of data from two populations: (1) COVERTE (ANRS-CO19), a French national cohort of 18 to 30-year-old patients HIV-infected since childhood, and (2) ENNS, a national cross-sectional population-based household survey on nutrition. Body mass index (BMI), blood pressure, waist circumference, fasting glucose, triglycerides, and HDL-, LDL- and total cholesterol were measured in both studies. Direct standardization on overweight and education level and logistic regression were used to compare the prevalence of metabolic abnormalities between the two populations.

RESULTS

Data from 268 patients from COVERTE and 245 subjects from ENNS were analyzed. Tobacco use was similar in both groups. HIV-infected patients had increased mean waist-to-hip ratio and triglycerides to HDL-cholesterol ratio and decreased mean HDL-cholesterol as compared to their counterparts from the general population in both genders. In HIV-infected patients, metabolic syndrome was identified in 13.2% of men (95% confidence interval [CI]: 7.1-19.2) and 10.4% (95% CI: 5.4-15.3) of women versus 10.6% (95%CI: 1.5-19.7) and 1.7% (95%CI: 0-4.1) in subjects from the general population, respectively.

CONCLUSION

Young adults infected with HIV since childhood had a higher prevalence of dyslipidemia and metabolically detrimental fat distribution than adults of same age of the general population, supporting close monitoring for cardiometabolic diseases.

Magnitude and associated factors of diabetes mellitus and hypertension among adult HIV-positive individuals receiving highly active antiretroviral therapy at Jugal Hospital, Harar, Ethiopia

BACKGROUND

People with HIV infection are at increased risk of noncommunicable diseases (NCDs). Diabetes mellitus (DM) and hypertension are recognized as the major NCDs. Except few findings in general population, there is no well-documented evidence on the magnitude of NCDs and associated factors among HIV-positive patients.

PURPOSE

The aim of this study was to determine the magnitude and associated factors of DM and hypertension among adult HIV-positive subjects receiving highly active antiretroviral therapy (HAART).

METHODS

A hospital-based cross-sectional study was conducted from February to April at Jugal Hospital, Harar, Eastern Ethiopia. Sociodemographic and anthropometric data and blood pressure (BP) were collected by senior clinical nurses. A total of 5 mL of venous blood was collected. Serum glucose and lipid profile were measured using the Autolab 18 clinical chemistry analyzer. Data were analyzed using STATA version 13.

RESULTS

A total of 425 HIV-infected individuals taking HAART of age ranging from 18 to 68 years were included. The prevalence of DM and hypertension were 7.1% (95% CI: 4.9-9.9) and 12.7% (95% CI: 9.8-16.2), respectively. Increased blood triglyceride (adjusted odds ratio [AOR] =4.7, 95% CI: 1.7-13.1), high BP (AOR =3.3, 95% CI: 1.1-9.5), and high baseline body mass index (BMI) (AOR =8.7, 95% CI: 2.4-31.8) were significantly associated with DM. In contrast, raised waist-hip ratio (AOR =4.6, 95% CI: 1.6-13.3), raised blood glucose (AOR =3.5, 95% CI: 1.1-11.4), increased total cholesterol (AOR =3.9, 95% CI: 1.3-11.9), high current BMI (AOR =3.8, 95% CI: 1.5-9.6), drinking alcohol (AOR =3.4, 95% CI: 1.5-8.1), CD4 count <500 cell/mL (AOR =2.7, 95% CI: 1.3-5.6), and longer duration of HAART (AOR =2.3, 95% CI: 1.1-5.1) were significantly associated with hypertension.

CONCLUSION

DM and hypertension were frequent among HIV patients on HAART, and they were linked to the well-known risk factors. Therefore, regular screening and monitoring of DM and hypertension before and after the initiation of HAART is of paramount importance.
