Item Association of Gut Intestinal Integrity and Inflammation with Insulin Resistance in Adults Living with HIV in Uganda(AIDS Patient Care and STDs, 2019) Reid, Michael J.A.; Ma, Yifei; Golovaty, Iya; Okello, Samson; Sentongo, Ruth; Feng, Maggie; Tsai, Alexander C.; Kakuhikire, Bernard; Tracy, Russell; Hunt, Peter W.; Siedner, Mark; Tien, Phyllis C.We conducted a cross-sectional study of 148 HIV+ on HIV antiretroviral therapy and 149 HIV- adults in Mbarara, Uganda, to estimate the association between HIV infection and homeostasis model assessment of insulin resistance (HOMA-IR) using multivariable regression analysis. In addition, we evaluated whether intestinal fatty acid-binding protein (I-FABP), monocyte activation markers soluble (s)CD14 and sCD163, and proinflammatory cytokine interleukin 6 (IL-6) mediated this association. HOMA-IR was greater among HIV+ than HIV- adults [median (interquartile range): 1.3 (0.7–2.5) vs. 0.9 (0.5–2.4); p = 0.008]. In models adjusted for sociodemographic variables, diet, hypertension, and smoking history, HIV infection was associated with 37% [95% confidence intervals (95% CIs): 5–77] greater HOMA-IR compared with HIV- participants. The magnitude of association was greater when I-FABP was included as a covariate although the additive effect was modest (40% CI: 8–82). By contrast adding sCD14 to the model was associated with greater HOMA-IR (59%; 95% CI: 21–109) among HIV+ participants compared with HIV- participants. Among HIV+ participants, greater CD4 nadir was non-significantly associated with greater HOMA-IR (22%; 95% CI: -2 to 52). Each 5-unit increase in body mass index (BMI; 49% greater HOMA-IR; 95% CI: 18–87) and female sex (71%; 95% CI: 17–150) remained associated in adjusted models. In this study of mainly normal-weight Ugandan adults, HIV infection, female sex, and greater BMI were all associated with greater insulin resistance (IR). This association was strengthened modestly after adjustment for sCD14, suggesting possible distinct immune pathways to IR that are independent of HIV or related to inflammatory changes occurring on HIV treatment.Item Biomass fuel as a risk factor for esophageal squamous cell carcinoma: a systematic review and meta-analysis(Environmental Health, 2019) Okello, Samson; Akello, Suzan Joan; Dwomoh, Emmanuel; Byaruhanga, Emmanuel; Opio, Christopher Kenneth; Zhang, Ruyang; Corey, Kathleen E.; Muyindike, Winnie R.; Ocama, Ponsiano; Christiani, David D.The link between use of solid biomass fuel (wood, charcoal, coal, dung, and crop residues) for cooking and/or heating and esophageal squamous cell carcinoma (ESCC) is inconclusive. Objective: We systematically reviewed the literature and performed a meta-analysis to determine whether cooking fuel type influences esophageal squamous cell carcinoma. Methods: We searched MEDLINE, EMBASE, Web of Knowledge and Cochrane Database of Systematic Reviews for studies investigating cooking fuel and ESCC from 2000 until March 2019. We performed random effects meta-analysis stratified by the continent, World Bank’s country income classifications and fuel type and calculated pooled odds ratios and 95% CIs for the risk of esophageal squamous cell carcinoma in biomass fuel users compared with non-users. Results: Our analysis included 16 studies (all case-control) with 16,189 participants (5233 cases and 10,956 controls) that compared risk of ESCC among those using nonsolid fuels and biomass fuels. We found use of biomass fuel was associated with Esophageal squamous cell carcinoma with a pooled odds ratio (OR) 3.02 (95% CI 2.22, 4.11, heterogeneity (I2) = 79%). In sub-group analyses by continent, Africa (OR 3.35, 95%CI 2.34, 4.80, I2 = 73.4%) and Asia (OR 3.08, 95%CI 1.27, 7.43, I2 = 81.7%) had the highest odds of ESCC. Use of wood as fuel had the highest odds of 3.90, 95% CI 2.25, 6.77, I2 = 63.5%). No significant publication bias was detected. Conclusions: Biomass fuel is associated with increased risk of Esophageal squamous cell carcinoma. Biomass fuel status should be considered in the risk assessment for Esophageal squamous cell carcinoma.Item Blood pressure trajectories and the mediated effects of body mass index and HIV‐related inflammation in a mixed cohort of people with and without HIV in rural Uganda(The Journal of Clinical Hypertension, 2019) Okello, Samson; Kim, June‐Ho; Sentongo, Ruth N.; Tracy, Russell; Tsai, Alexander C.; Kakuhikire, Bernard; Siedner, Mark J.We sought to describe changes in blood pressure and estimate the effect of HIV on blood pressure (BP) over 4 years of observation in a cohort of 155 HIV‐infected adults (≥40 years) on antiretroviral therapy (ART) and 154 sex‐ and age‐quartilematched, population‐based, HIV‐uninfected controls for four years in rural Uganda, we compared changes in blood pressure (BP) by HIV serostatus and tested whether body mass index and inflammation (high‐sensitivity C‐reactive protein and interleukin‐ 6) and immune activation (sCD14 and sCD163) mediated the effects of HIV on BP using hierarchical multivariate and two‐stage parametric regression models. Overall HIV‐uninfected participants had higher mean BP than HIV‐infected counterparts (differences in trend P < 0.0001 for diastolic BP and P = 0.164 for systolic BP). After initial declines in BP in both groups between years 1 and 2, BP moderately increased in both groups through year 4, with greater change over time observed in the HIVuninfected group. Body mass index mediated 72% (95%CI 57, 97) of the association between HIV and systolic BP. We found a minimal mediating effect of sCD14 on the relationship between HIV and SBP (9%, 95% CI 5%, 21%), but found no association between other HIV‐related biomarkers. Over four years of observation, HIV‐infected people in rural Uganda have lower BP than HIV‐uninfected counterparts despite having higher levels of inflammation. BMI, rather than measures of HIV‐associated inflammation, explained a majority of the difference in BP observed.Item Cost-effectiveness analysis of integrating screening and treatment of selected non-communicable diseases into HIV/AIDS treatment in Uganda(Journal of the International AIDS Society, 2020) Sando, David; Kintu, Alexander; Okello, Samson; Kawungezi, Peter Chris; Guwatudde, David; Mutungi, Gerald; Muyindike, Winnie; Menzies, Nicolas A.; Danaei, Goodarz; Verguet, StephaneDespite growing enthusiasm for integrating treatment of non-communicable diseases (NCDs) into human immunodeficiency virus (HIV) care and treatment services in sub-Saharan Africa, there is little evidence on the potential health and financial consequences of such integration. We aim to study the cost-effectiveness of basic NCD-HIV integration in a Ugandan setting. Methods: We developed an epidemiologic-cost model to analyze, from the provider perspective, the cost-effectiveness of integrating hypertension, diabetes mellitus (DM) and high cholesterol screening and treatment for people living with HIV (PLWH) receiving antiretroviral therapy (ART) in Uganda. We utilized cardiovascular disease (CVD) risk estimations drawing from the previously established Globorisk model and systematic reviews; HIV and NCD risk factor prevalence from the World Health Organization’s STEPwise approach to Surveillance survey and global databases; and cost data from national drug price lists, expert consultation and the literature. Averted CVD cases and corresponding disability-adjusted life years were estimated over 10 subsequent years along with incremental cost-effectiveness of the integration. Results: Integrating services for hypertension, DM, and high cholesterol among ART patients in Uganda was associated with a mean decrease of the 10-year risk of a CVD event: from 8.2 to 6.6% in older PLWH women (absolute risk reduction of 1.6%), and from 10.7 to 9.5% in older PLWH men (absolute risk reduction of 1.2%), respectively. Integration would yield estimated net costs between $1,400 and $3,250 per disability-adjusted life year averted among older ART patients. Conclusions: Providing services for hypertension, DM and high cholesterol for Ugandan ART patients would reduce the overall CVD risk among these patients; it would amount to about 2.4% of national HIV/AIDS expenditure, and would present a cost-effectiveness comparable to other standalone interventions to address NCDs in low- and middle-income country settings.Item Electrocardiographic Evidence of Cardiac Disease by Sex and HIV Serostatus in Mbarara, Uganda(Global heart, 2019) Kentoffio, Katie; Albano, Alfred; Koplan, Bruce; Feng, Maggie; Muthalaly, Rahul G.; Campbell, Jeffrey I.; Sentongo, Ruth; Tracy, Russell P.; Peck, Robert; Okello, Samson; Tsai, Alexander C.; Siedner, Mark J.Numerous studies in the United States and Europe have demonstrated an increased risk for cardiovascular disease (CVD) among persons living with HIV (PLWH).[1] The relationship between HIV and subsequent CVD has not been as well-established in sub-Saharan Africa (SSA). PLWH in SSA have a high burden of untreated risk factors, but results vary regarding surrogate markers of CVD. Data on outcomes, such as stroke or myocardial infarction, are limited. An analysis of data from the SMART trial found that PLWH had a high prevalence of ECG abnormalities at baseline, which predicted CVD risk over the study period.[2] We investigated the prevalence of ECG abnormalities by HIV serostatus in rural Uganda to estimate differences in CVD risk. As secondary aims, we assessed a) ECG evidence of ischemic coronary artery disease by HIV serostatus and b) sex-based differences in ECG findings.Item HIV infection, pulmonary tuberculosis and COPD in rural Uganda: A cross-sectional study(Lung, 2018) North, Crystal M.; Allen, Joseph G.; Okello, Samson; Sentongo, Ruth; Kakuhikire, Bernard; Ryan, Edward T.; Tsai, Alexander C.; Christiani, David C.; Siedner, Mark J.HIV is associated with chronic obstructive pulmonary disease (COPD) in high resource settings. Similar relationships are less understood in low resource settings. We aimed to estimate the association between HIV infection, tuberculosis and COPD in rural Uganda. Methods: The Uganda Non-Communicable Diseases and Aging Cohort study observes people 40 years and older living with HIV (PLWH) on antiretroviral therapy, and population-based HIV-uninfected controls in rural Uganda. Participants completed respiratory questionnaires and post-bronchodilator spirometry. Results: Among 269 participants with spirometry, median age was 52 (IQR 48–55), 48% (n=130) were ever-smokers, and few (3%, n=9) reported a history of COPD or asthma. All participants with prior tuberculosis (7%, n=18) were PLWH. Among 143 (53%) PLWH, median CD4 count was 477 cells/mm3 and 131 (92%) were virologically suppressed. FEV1 was lower among older individuals (−0.5 %pred/year, 95% CI 0.2–0.8, p<0.01) and those with a history of tuberculosis (−14.4 %pred, 95% CI −23.5 - −5.3, p < 0.01). COPD was diagnosed in 9 (4%) participants, eight of whom (89%) were PLWH, 6 of whom (67%) had a history of tuberculosis, and all of whom (100%) were men. Among 287 participants with complete symptom questionnaires, respiratory symptoms were more likely among women (AOR 3.9, 95% CI 2.0–7.7, p<0.001) and those in homes cooking with charcoal (AOR 3.2, 95% CI 1.4–7.4, p=0.008).Item Ideal Cardiovascular Health and Carotid Atherosclerosis in a Mixed Cohort of HIV-Infected and Uninfected Ugandans(AIDS research and human retroviruses, 2017) Feinstein, Matthew J.; Kim, June-Ho; Bibangambah, Prossy; Sentongo, Ruth; Martin, Jeffrey N.; Tsai, Alexander C.; Bangsberg, David R.; Hemphill, Linda; Triant, Virginia A.; Boum II, Yap; Hunt, Peter W.; Okello, Samson; Siedner, Mark J.Preventable cardiovascular disease (CVD) risk factors are responsible for the majority of CVD-related deaths, and are increasingly recognized as a cause of morbidity and mortality for HIV-infected persons taking antiretroviral therapy (ART). Simplified tools such as the American Heart Association’s ideal cardiovascular health (iCVH) construct may identify and prognosticate CVD risk in resource-limited settings. No studies have evaluated iCVH metrics in sub-Saharan Africa or among HIV-infected adults. Thus, the central aim of this study was to compare levels of iCVH metrics and their correlations with carotid atherosclerosis for HIV-infected adults versus uninfected controls in a well-phenotyped Ugandan cohort. We analyzed the prevalence of iCVH metrics in a mixed cohort of HIV-infected persons on stable ART and uninfected, population-based comparators in Mbarara, Uganda. We also assessed the validity of iCVH by correlating iCVH values with common carotid intima media thickness (CCIMT). HIV-infected persons had a mean of 4.9 (SD 1.1) iCVH metrics at ideal levels versus 4.3 (SD 1.2) for uninfected controls ( p = .002). This difference was largely driven by differences in blood pressure, blood glucose, and diet. In multivariable-adjusted linear regression models, each additional iCVH metric at an ideal level was associated with a significant 0.024mm decrease in CCIMT ( p < .001).HIV-infected persons on ART in rural Uganda had more iCVH metrics at ideal levels than uninfected persons. The difference appeared driven by factors that are putatively influenced by access to routine medical care. Composite scores of iCVH metrics were associated with subclinical atherosclerosis and more predictive of atherosclerosis for uninfected persons.Item Integrating care for non-communicable diseases into routine HIV services: key considerations for policy design in sub-Saharan Africa(Journal of the International AIDS Society, 2020) Kintu, Alexander; Sando, David; Okello, Samson; Mutungi, Gerald; Guwatudde, David; Menzies, Nicolas A.; Danaei, Goodarz; Verguet, StephaneThere is great interest for integrating care for non-communicable diseases (NCDs) into routine HIV services in sub-Saharan Africa (SSA) due to the steady rise of the number of people who are ageing with HIV. Suggested health system approaches for intervening on these comorbidities have mostly been normative, with little actionable guidance on implementation, and on the practical, economic and ethical considerations of favouring people living with HIV (PLHIV) versus targeting the general population. We summarize opportunities and challenges related to leveraging HIV treatment platforms to address NCDs among PLHIV. We emphasize key considerations that can guide integrated care in SSA and point to possible interventions for implementation. Discussion: Integrating care offers an opportunity for effective delivery of NCD services to PLHIV, but may be viewed to unfairly ignore the larger number of NCD cases in the general population. Integration can also help maintain the substantial health and economic benefits that have been achieved by the global HIV/AIDS response. Implementing interventions for integrated care will require assessing the prevalence of common NCDs among PLHIV, which can be achieved via increased screening during routine HIV care. Successful integration will also necessitate earmarking funds for NCD interventions in national budgets. Conclusions: An expanded agenda for addressing HIV-NCD comorbidities in SSA may require adding selected NCDs to conditions that are routinely monitored in PLHIV. Attention should be given to mitigating potential tradeoffs in the quality of HIV services that may result from the extra responsibilities borne by HIV health workers. Integrated care will more likely be effective in the context of concurrent health system reforms that address NCDs in the general population, and with synergies with other HIV investments that have been used to strengthen health systems.Item Lung function and atherosclerosis: a cross‑sectional study of multimorbidity in rural Uganda(BMC pulmonary medicine, 2022) Gilbert, Rebecca F.; Cichowitz, Cody; Bibangambah, Prossy; Kim, June‑Ho; Hemphill, Linda C.; Yang, Isabelle T.; Sentongo, Ruth N.; Kakuhikire, Bernard; Christiani, David C.; Tsai, Alexander C.; Okello, Samson; Siedner, Mark J.; North, Crystal M.Chronic obstructive pulmonary disease (COPD) is a leading cause of global mortality. In high-income settings, the presence of cardiovascular disease among people with COPD increases mortality and complicates longitudinal disease management. An estimated 26 million people are living with COPD in sub-Saharan Africa, where risk factors for co-occurring pulmonary and cardiovascular disease may differ from high-income settings but remain uncharacterized. As non-communicable diseases have become the leading cause of death in sub-Saharan Africa, defining multimorbidity in this setting is critical to inform the required scale-up of existing healthcare infrastructure. Methods: We measured lung function and carotid intima media thickness (cIMT) among participants in the UGANDAC Study. Study participants were over 40 years old and equally divided into people living with HIV (PLWH) and an age- and sex-similar, HIV-uninfected control population. We fit multivariable linear regression models to characterize the relationship between lung function (forced expiratory volume in one second, FEV1) and pre-clinical atherosclerosis (cIMT), and evaluated for effect modification by age, sex, smoking history, HIV, and socioeconomic status. Results: Of 265 participants, median age was 52 years, 125 (47%) were women, and 140 (53%) were PLWH. Most participants who met criteria for COPD were PLWH (13/17, 76%). Median cIMT was 0.67 mm (IQR: 0.60 to 0.74), which did not differ by HIV serostatus. In models adjusted for age, sex, socioeconomic status, smoking, and HIV, lower FEV1 was associated with increased cIMT (β = 0.006 per 200 mL FEV1 decrease; 95% CI 0.002 to 0.011, p = 0.01). There was no evidence that age, sex, HIV serostatus, smoking, or socioeconomic status modified the relationship between FEV1 and cIMT. Conclusions: Impaired lung function was associated with increased cIMT, a measure of pre-clinical atherosclerosis, among adults with and without HIV in rural Uganda. Future work should explore how co-occurring lung and cardiovascular disease might share risk factors and contribute to health outcomes in sub-Saharan Africa.Item One-year Incidence and Standardized Mortality Rates for Esophageal Squamous Cell Carcinoma in Uganda(Research Square, 2021) Okello, Samson; Byaruhanga, Emmanuel B.; Lumori, Boniface Amanee Elias; Akello, Suzan Joan; Dwomoh, Emmanuel; Opio, Christopher Kenneth; Ocama, Ponsiano; Muyindike, Winnie R.; David, Christiani C.; Corey, Kathleen E.Little is known about the survival of patients with esophageal squamous cell cancer in resource limited settings. Objectives: We sought to determine the incidence of one-year all-cause mortality and age-standardized mortality rates for esophageal squamous cell carcinoma in Uganda. Methods: Prospective cohort of 92 participants with histologically confirmed esophageal squamous cell cancer at Mbarara Regional Referral Hospital, southwestern Uganda. Participants were enrolled between January 2018 and March 2020 and followed until death. We used Kaplan-Meier methods to determine allcause mortality and median survival time; Cox regression to determine predictors of survival; and determined age-standardized mortality rates (SMR) using the WHO standard population. Results: All 92 participants contributed a total 353.8 months at risk, 89 (96.7%) died representing an incidence rate of 251.5 (95% CI 204.3, 309.6) per 1000 person-months. The difference in the one-year risk of all-cause mortality among men and women was negative 6.4 percentage points. The overall SMR was 9.96 (95%CI 7.63, 12.29) per 100,000 and median survival time was 3.03 (95% CI 2.60, 3.47), shortest (1.77 months) among men younger than 45 and longest (7.77 months) among women aged 75 years or greater. In a fully adjusted model, high socioeconomic status predicted longer survival while increasing age and low socioeconomic status predicted shorter survival. Conclusion: After diagnosis, the one-year incidence rates of all-cause mortality and age-standardized mortality rates among ESCC patients in rural Uganda are high. Initiatives to improve access to oncology care for diagnosis and treatment should be prioritized to improve overall survival.Item Prevalence and correlates of carotid plaque in a mixed HIV‑serostatus cohort in Uganda(BMC Cardiovascular Disorders, 2021) Bibangambah, Prossy; Hemphill, Linda C.; Acan, Moses; Tsai, Alexander C.; Sentongo, Ruth N.; Kim, June‑Ho; Yang, Isabelle T.; Siedner, Mark J.; Okello, SamsonThe extent to which the risk of atherosclerotic cardiovascular disease (ACVD) is increased among people living with HIV (PLWH) in sub-Saharan Africa remains unknown. Setting: Cross-sectional analysis nested within the Ugandan Noncommunicable Diseases and Aging Cohort, including PLWH in rural Uganda > 40 years taking antiretroviral therapy (ART) for at least 3 years, and a population-based control group of HIV-uninfected age- and sex-matched persons. Methods: We conducted carotid ultrasonography and collected ACVD risk factor data. Our outcome of interest was carotid plaque, defined as > 1.5 mm thickness from the intima-lumen interface to the media-adventitia interface. We fit multivariable logistic regression models to estimate correlates of carotid plaque including HIV-specific and traditional cardiovascular risk factors. Results: We enrolled 155 (50.2%) PLWH and 154 (49.8%) HIV-uninfected comparators, with a mean age of 51.4 years. Among PLWH, the median CD4 count was 433 cells/mm3 and 97.4% were virologically suppressed. Carotid plaque prevalence was higher among PLWH (8.4% vs 3.3%). HIV infection (aOR 3.90; 95% CI 1.12–13.60) and current smokers (aOR 6.60; 95% CI 1.22–35.80) had higher odds of carotid plaque, whereas moderate (aOR 0.13, 95% CI 0.01–1.55) and vigorous intensity of physical activity (aOR 0.34, 95% CI 0.07–1.52) were associated with decreased odds of carotid plaque. Conclusion: In rural Uganda, PLWH have higher prevalence of carotid plaque compared to age- and sex-matched HIV-uninfected comparators. Future work should explore how biomedical and lifestyle modifications might reduce atherosclerotic burden among PLWH in the region.Item Quantifying the burden of cardiovascular diseases among people living with HIV in sub-Saharan Africa: findings from a modeling study for Uganda(Journal of Global Health Reports, 2020) Kintu, Alexander; Sando, David; Guwatudde, David; Bahendeka, Silver; Kawungezi, Peter C.; Mutungi, Gerald; Muyindike, Winnie; Menzies, Nicolas; Okello, Samson; Danaei, Goodarz; Verguet, StéphaneThe burden of non-communicable diseases (NCDs) is rapidly increasing in low- and middle-income countries, but remains largely unknown among people living with HIV (PLWH) in most sub-Saharan African countries. Methods We estimated the proportion of PLWH in Uganda with raised blood pressure and high total cholesterol, and used a modified cardiovascular disease (CVD) risk prediction model (Globorisk) to assess the 10-year risk of atherosclerotic cardiovascular disease using individual-level data on cardiometabolic risk factors, population-level data on HIV prevalence and ART coverage, and the impact of HIV on blood pressure and cholesterol. Results Among PLWH aged 30 to 69 years, the prevalence of raised blood pressure was 30% (95% uncertainty range, UR=27-33%) in women and 26% in men (95% UR=23-29%). The predicted mean 10-year CVD risk was 5% for HIV-infected women, and 6% for HIV-infected men. Five percent (n=41,000) of PLWH may experience a CVD event from 2016 to 2025 with an estimated 38% of these events being fatal. Full ART coverage would have little effect on the predicted number of CVD cases. Conclusions Despite having a high prevalence of raised blood pressure, the burden of atherosclerotic CVD among PLWH in Uganda remains low. ART programs should prioritize routine screening and treatment of raised blood pressure. An approach of using HIV treatment delivery platforms to deliver care for NCDs may miss the larger burden of disease among HIV-uninfected individuals that are not routinely seen at health facilities.Item To fast or not to fast: Lipid measurement and cardiovascular disease risk estimation in rural sub-Saharan Africa(Journal of global health, 2020) Yang, Isabelle T.; Hemphill, Linda C.; Kim, June-Ho; Bibangambah, Prossy; Sentongo, Ruth; Kakuhire, Bernard; Plutzky, Jorge; Boum II, Yap; Tsai, Alexander C.; Okello, Samson; Siedner, Mark J.Cardiovascular disease (CVD) morbidity and mortality are increasing in sub-Saharan Africa (sSA), highlighting the need for tools to enable CVD risk stratification in the region. Although non-HDL-cholesterol (nHDL-C) has been promoted as a method to measure lipids without a requirement for fasting in the USA, its diagnostic validity has not been assessed in sSA. We sought to estimate: 1) the association between LDL-cholesterol (LDL-C) and nHDL-C, 2) the impact of fasting on their measurement, and 3) their correlation with carotid atherosclerosis, within a rural Ugandan population with high HIV prevalence. Methods We collected traditional CVD risk factors, blood for serum lipid levels, self-reported fasting status, and performed carotid ultrasonography in 301 participants in rural Uganda. We fit regression models, stratified by fasting status, to estimate associations between carotid intima media thickness (cIMT), LDL-C, and nHDL-C. Results Median age was 50 years (interquartile range = 46-54), 49% were female, 51% were HIV-positive, and at the time of blood collection, 70% had fasted overnight. Mean LDL-C, nHDL-C, and triglycerides in the non-fasting and fasting groups were 85 vs 88 mg/dL (P = 0.39), 114 vs 114 mg/dL (P = 0.98), and 130 vs 114 mg/dL (P = 0.05) mg/dL, respectively. In unadjusted models, mean cIMT (mm) was associated with both increased LDL-C (β = 0.0078 per 10mg/dL, P < 0.01) and nHDL-C (β = 0.0075, P < 0.01), and these relationships were similar irrespective of fasting status. After adjustment for traditional CVD risk factors, we observed similar associations, albeit with muted effect sizes within the fasting group. Conclusions We found a high correlation between LDL-C and nHDL-C, and both were correlated with cIMT, irrespective of fasting or HIV serostatus in rural Uganda. Our findings support use of either fasting or non-fasting serum lipids for CVD risk estimation in rural sSA.Item Treated HIV Infection and Progression of Carotid Atherosclerosis in Rural Uganda: A Prospective Observational Cohort Study(Journal of the American Heart Association, 2021) Siedner, Mark J.; Bibangambah, Prossy; Kim, June-Ho; Lankowski, Alexander; Chang, Jonathan L.; Yang, Isabelle T.; Kwon, Douglas S.; North, Crystal M.; Triant, Virginia A.; Longenecker, Christopher; Ghoshhajra, Brian; Peck, Robert N.; Sentongo, Ruth N.; Gilbert, Rebecca; Kakuhikire, Bernard; Boum II, Yap; Haberer, Jessica E.; Martin, Jeffrey N.; Tracy, Russell; Hunt, Peter W.; Bangsberg, David R.; Tsai, Alexander C.; Hemphill, Linda C.; Okello, SamsonAlthough ≈70% of the world’s population of people living with HIV reside in sub-Saharan Africa, there are minimal prospective data on the contributions of HIV infection to atherosclerosis in the region. METHODS AND RESULTS: We conducted a prospective observational cohort study of people living with HIV on antiretroviral therapy >40 years of age in rural Uganda, along with population-based comparators not infected with HIV. We collected data on cardiovascular disease risk factors and carotid ultrasound measurements annually. We fitted linear mixed effects models, adjusted for cardiovascular disease risk factors, to estimate the association between HIV serostatus and progression of carotid intima media thickness (cIMT). We enrolled 155 people living with HIV and 154 individuals not infected with HIV and collected cIMT images at 1045 visits during a median of 4 annual visits per participant (interquartile range 3–4, range 1–5). Age (median 50.9 years) and sex (49% female) were similar by HIV serostatus. At enrollment, there was no difference in mean cIMT by HIV serostatus (0.665 versus 0.680 mm, P=0.15). In multivariable models, increasing age, blood pressure, and non–high- density lipoprotein cholesterol were associated with greater cIMT (P<0.05), however change in cIMT per year was also no different by HIV serostatus (0.004 mm/year for HIV negative [95% CI, 0.001–0.007 mm], 0.006 mm/year for people living with HIV [95% CI, 0.003–0.008 mm], HIV×time interaction P=0.25). CONCLUSIONS: In rural Uganda, treated HIV infection was not associated with faster cIMT progression. These results do not support classification of treated HIV infection as a risk factor for subclinical atherosclerosis progression in rural sub-Saharan Africa.
