Cumulative Human Immunodeficiency Virus (HIV)-1 Viremia Is Associated With Increased Risk of Multimorbidity Among US Women With HIV, 1997-2019

Higher non-HIV-comorbidity burden in long-term survivors

OBJECTIVE

The possible differences in comorbidity burden were examined between people with longstanding HIV infection and those with shorter HIV duration of the same calendar age.

DESIGN

We performed a single-centre retrospective cohort analysis comparing long-term HIV survivors (LTS) diagnosed with HIV before 1996 (pre-HAART), with an age-matched and gender-matched group diagnosed after 2006 [modern ART era (mART)].

METHODS

Demographic and outcome data up to 1 May 2023 were obtained from electronic health records as well as from digitalized paper charts. Nine comorbidity domains were defined to overlook the comorbidity burden as on 1 May 2023: cardiovascular, musculoskeletal, neurological, oncological, liver, pulmonary, renal, psychiatric/cognitive, and metabolic.

RESULTS

Eighty-eight LTS and 88 people diagnosed in the modern ART era were included in the analysis. Median age in both groups was 60 years. LTS had a higher mean number of comorbidity domains than controls (2.6 vs. 1.9; P  = .001). In both LTS and mART groups, metabolic and cardiovascular comorbidity was most prevalent (metabolic 70.5 and 52.3%, respectively, cardiovascular 44.3 and 38.6%, respectively). When stratified according to age, the distribution of the number of comorbidities for LTS roughly resembled the 10 years older mART subgroup. In a multivariate analysis, total ART duration and age were found to be statistically significantly associated with the number of comorbidity domains.

CONCLUSION

Our analysis suggests that LTS have a higher comorbidity burden compared with people diagnosed in the modern ART era of similar calendar age.

Impact of Depression and HIV Symptoms on Glycemic Outcomes among Patients with HIV and Type 2 Diabetes: A Clinical Cohort Study

Type 2 diabetes (T2DM) and depressive symptoms frequently co-occur among people with HIV (PWH). Depression may impact diabetes management in PWH. This study evaluated the prevalence of concurrent T2DM and depression among PWH and the impact of depression and HIV symptoms on glycemic outcomes (hemoglobin A1c [A1c], blood glucose [BG]) among people with both HIV and T2DM. We conducted a secondary analysis in the CFAR Network of Integrated Clinical Systems, a multisite clinical cohort including a diverse population of PWH in care from July 2005 through July 2023. Linear regression and linear mixed models were used to estimate the association between depression, HIV symptoms, and glycemic outcomes (A1C, BG) at baseline and over time. Of the 18,562 PWH, 2,945 (16%) also had T2DM. PWH with T2DM were older (56 vs. 49 years) and more often non-Hispanic Black and cis-gender men. The prevalence of depression was not significantly different between PWH with or without T2DM (20% vs. 21%) although more PWH with T2DM received antidepressant medications. Among people with both HIV and T2DM, HIV baseline symptoms and depression were not associated with a change in A1c. Increases in time-updated HIV symptom scores were associated with random (non-fasting) BG levels, with each additional HIV symptom resulting in 0.8 mg/dL increase in random BG level (95% CI: 0.04-1.60, p = 0.04). The prevalence of T2DM was higher among PWH than in the general population. Although depression appears to be well managed, other factors impacting glycemic outcomes among people with both HIV and T2DM require further study.

Viremia Does Not Independently Predict Cardiovascular Disease in People With HIV: A RESPOND Cohort Study

Background

HIV viremia has been considered a cardiovascular disease (CVD) risk factor, but many studies have had insufficient data on potential confounders. We explored the association between viremia and CVD after adjusting for established risk factors and analyzed whether consideration of viremia would improve CVD prediction.

Methods

Adults from RESPOND were followed from the first date with available data until the first of rigorously defined CVD, loss to follow-up, death, or administrative censoring. We first analyzed the associations between 6 measures of viremia (time-updated, before antiretroviral therapy [ART], viremia category, and measures of cumulative viremia) and CVD after adjusting for the variables in the D:A:D CVD score (age, sex/gender, smoking, family history, diabetes, recent abacavir, CD4 count, blood pressure, cholesterol, high-density lipoprotein, cumulative use of stavudine, didanosine, indinavir, lopinavir, and darunavir). We subsequently compared predictive performance with and without viremia in 5-fold internal cross-validation.

Results

A total of 547 events were observed in 17 497 persons (median follow-up, 6.8 years). Although some viremia variables were associated with CVD in univariable analyses, there were no statistically significant associations after adjusting for potential confounders, neither for measures of current viral load, pre-ART viral load, highest viremia category during ART, nor cumulative viremia (modeled both as total cumulative viremia, cumulative viremia during ART, and recent cumulative viremia). Consistently, none of the viremia variables improved prediction capacity.

Conclusions

In this large international cohort, HIV viremia was not associated with CVD when adjusting for established risk factors. Our results did not show viremia to be predictive of CVD among people with HIV.

Consequences of low-level viremia among women with HIV in the United States

OBJECTIVE

Investigate the outcomes of women with HIV (WWH) with low-level viremia (LLV).

DESIGN

The prevalence of LLV and potential clinical sequelae, such as virologic failure and non-AIDS comorbidity (NACM) development, are poorly characterized among WWH.

METHODS

We analyzed data from the Women's Interagency HIV Study among WWH enrolled from 2003 to 2020 who reported antiretroviral therapy use at least 1 year followed by an HIV-1 viral load less than 200 copies/ml. Consecutive viral load measurements from four semi-annual visits were used to categorize women at baseline as having: virologic suppression (all viral load undetectable), intermittent LLV (iLLV; nonconsecutive detectable viral load up to 199 copies/ml), persistent LLV (pLLV; at least two consecutive detectable viral load up to 199 copies/ml), or virologic failure (any viral load ≥200 copies/ml). Adjusted hazard ratios quantified the association of virologic category with time to incident virologic failure and multimorbidity (≥2 of 5 NACM) over 5-year follow-up.

RESULTS

Of 1598 WWH, baseline median age was 47 years, 64% were Black, 21% Hispanic, and median CD4 + cell count was 621 cells/μl. After excluding 275 women (17%) who had virologic failure at baseline, 58, 19, and 6% were categorized as having virologic suppression, iLLV, and pLLV, respectively. Compared with WWH with virologic suppression, the adjusted hazard ratio [aHR; 95% confidence interval (CI)] for incident virologic failure was 1.88 (1.44-2.46) and 2.51 (1.66-3.79) for iLLV and pLLV, respectively; and the aHR for incident multimorbidity was 0.81 (0.54-1.21) and 1.54 (0.88-2.71) for iLLV and pLLV, respectively.

CONCLUSION

Women with iLLV and pLLV had an increased risk of virologic failure. Women with pLLV had a trend towards increased multimorbidity risk.

Associations between social determinants of health and comorbidity and multimorbidity in people of black ethnicities with HIV

OBJECTIVE

Social determinants of health (SDH) are important determinants of long-term conditions and multimorbidity in the general population. The intersecting relationship between SDH and multimorbidity in people with HIV remains poorly studied.

DESIGN

A cross-sectional study investigating the relationships between eight socio-economic parameters and prevalent comorbidities of clinical significance and multimorbidity in adults of African ancestry with HIV aged 18-65 years in South London, UK.

METHODS

Multivariable logistic regression analysis was used to evaluate associations between SDH and comorbidities and multimorbidity.

RESULTS

Between September 2020 and January 2022, 398 participants (median age 52 years, 55% women) were enrolled; 85% reported at least one SDH and 72% had at least one comorbidity. There were no associations between SDH and diabetes mellitus or kidney disease, few associations between SDH (job and food insecurity) and cardiovascular or lung disease, and multiple associations between SDH (financial, food, housing and job insecurity, low educational level, social isolation, and discrimination) and poor mental health or chronic pain. Associations between SDH and multimorbidity mirrored those for constituent comorbidities.

CONCLUSION

We demonstrate strong associations between SDH and poor mental health, chronic pain and multimorbidity in people of black ethnicities living with HIV in the UK. These findings highlight the likely impact of enduring socioeconomic hardship in these communities and underlines the importance of holistic health and social care for people with HIV to address these adverse psychosocial conditions.

Aging-Related Comorbidity Burden Among Women and Men With or At-Risk for HIV in the US, 2008-2019

Importance

Despite aging-related comorbidities representing a growing threat to quality-of-life and mortality among persons with HIV (PWH), clinical guidance for comorbidity screening and prevention is lacking. Understanding comorbidity distribution and severity by sex and gender is essential to informing guidelines for promoting healthy aging in adults with HIV.

Objective

To assess the association of human immunodeficiency virus on the burden of aging-related comorbidities among US adults in the modern treatment era.

Design, Setting, and Participants

This cross-sectional analysis included data from US multisite observational cohort studies of women (Women's Interagency HIV Study) and men (Multicenter AIDS Cohort Study) with HIV and sociodemographically comparable HIV-seronegative individuals. Participants were prospectively followed from 2008 for men and 2009 for women (when more than 80% of participants with HIV reported antiretroviral therapy use) through last observation up until March 2019, at which point outcomes were assessed. Data were analyzed from July 2020 to April 2021.

Exposures

HIV, age, sex.

Main Outcomes and Measures

Comorbidity burden (the number of total comorbidities out of 10 assessed) per participant; secondary outcomes included individual comorbidity prevalence. Linear regression assessed the association of HIV status, age, and sex with comorbidity burden.

Results

A total of 5929 individuals were included (median [IQR] age, 54 [46-61] years; 3238 women [55%]; 2787 Black [47%], 1153 Hispanic or other [19%], 1989 White [34%]). Overall, unadjusted mean comorbidity burden was higher among women vs men (3.4 [2.1] vs 3.2 [1.8]; P = .02). Comorbidity prevalence differed by sex for hypertension (2188 of 3238 women [68%] vs 2026 of 2691 men [75%]), psychiatric illness (1771 women [55%] vs 1565 men [58%]), dyslipidemia (1312 women [41%] vs 1728 men [64%]), liver (1093 women [34%] vs 1032 men [38%]), bone disease (1364 women [42%] vs 512 men [19%]), lung disease (1245 women [38%] vs 259 men [10%]), diabetes (763 women [24%] vs 470 men [17%]), cardiovascular (493 women [15%] vs 407 men [15%]), kidney (444 women [14%] vs 404 men [15%]) disease, and cancer (219 women [7%] vs 321 men [12%]). In an unadjusted model, the estimated mean difference in comorbidity burden among women vs men was significantly greater in every age strata among PWH: age under 40 years, 0.33 (95% CI, 0.03-0.63); ages 40 to 49 years, 0.37 (95% CI, 0.12-0.61); ages 50 to 59 years, 0.38 (95% CI, 0.20-0.56); ages 60 to 69 years, 0.66 (95% CI, 0.42-0.90); ages 70 years and older, 0.62 (95% CI, 0.07-1.17). However, the difference between sexes varied by age strata among persons without HIV: age under 40 years, 0.52 (95% CI, 0.13 to 0.92); ages 40 to 49 years, -0.07 (95% CI, -0.45 to 0.31); ages 50 to 59 years, 0.88 (95% CI, 0.62 to 1.14); ages 60 to 69 years, 1.39 (95% CI, 1.06 to 1.72); ages 70 years and older, 0.33 (95% CI, -0.53 to 1.19) (P for interaction = .001). In the covariate-adjusted model, findings were slightly attenuated but retained statistical significance.

Conclusions and Relevance

In this cross-sectional study, the overall burden of aging-related comorbidities was higher in women vs men, particularly among PWH, and the distribution of comorbidity prevalence differed by sex. Comorbidity screening and prevention strategies tailored by HIV serostatus and sex or gender may be needed.
