Background: Longitudinal measures of viral load (VL) are critical in monitoring the HIV status. While multiple lab indicators exist for monitoring measures of VL, research on clustering historical/longitudinal VL measures is limited. Analyzing longitudinal VL patterns rather than aggregated measures offers deeper insights into HIV status. This study uses functional data clustering to classify longitudinal VL patterns and characterize each cluster by demographics, comorbidities, social behaviors, and CD4 count. Methods: Adult PWH diagnosed from 2005 to 2015 in South Carolina with a 5-year minimum follow-up were included. We compared functional principal component analysis (FPCA), K-means, hierarchical clustering, and Gaussian mixture models for classification and found FPCA yielded the best results. ANOVA was used to compare VL characteristics, demographics, comorbidities, substance uses, and longitudinal CD4 count across clusters. Results: Results obtained from FPCA could best distinguish the characteristics and patterns into four clusters. A total of 5916 PWH were grouped into long-term VS group (Cluster 1, 17.3%), short-term VS group (Cluster 2, 29.8%), suboptimal VS group (Cluster 3, 28.3%), and viral failure group (Cluster 4, 24.9%). In the long-term VS group with an average of 11-year follow-up, PWH displayed sustained VS (95.3%) and lower mean CD4 count (95.3%) than other clusters. The short-term VS group had shorter follow-up (6 years), more comorbidities (31.4%), and lower percentage of time with low CD4 count (79.9%). In suboptimal VS group, PWH were mostly under 30 years old (44.8%) and Black (77.2%), with relatively lower mean VL (92.9%) and lower VR history (18.4%). In the viral failure group, PWH had higher mean VL (40.6%) and lower mean CD4 count (34.7%). Discussion: The findings highlight the impact of continuous clustering in understanding the distinct viral profiles of PWH and emphasize the importance of tailored treatment and insights to target interventions for all PWH.

This study explored relationships between neurocognitive impairment (NCI), engagement in HIV care, and functional disability among sexual minority men aged 50 years or older living with HIV, chronic pain, and recent substance use. Sixty-three participants completed cross-sectional assessments including a neurocognitive screening measure, self-reported HIV medication adherence, past-year attendance at HIV-care appointments, and indices of pain and functional impairment. Mean participant age was 57.2 years; most identified as White (55%), followed by Black/African American (42%). On average, participants reported moderate pain; 66.7% met DSM-5 criteria for a substance use disorder. Average Montreal Cognitive Assessment (MoCA) performance reflected mild NCI. Regression analyses indicated an association between poorer MoCA performance and past-year missed HIV-care appointments (B = -0.09, t (59) = -3.10, p = 0.004). Self-reported cognitive impairment was associated with more missed HIV-care visits (B = 0.20, t (59) = 4.82, p < 0.001) and greater functional disability, whereas poorer semantic fluency was associated with fewer missed HIV-care visits (B = -0.49, t (59) = -3.99, p < 0.001). Increased brief neuropsychological assessment and linkage to tailored interventions for HIV-care engagement and substance use mitigation are warranted to support PLWH with NCI in clinical care.

Background: Atherogenic index of plasma (AIP) and high-sensitivity C-reactive protein (hsCRP) levels which are strong predictors of the risk of cardiovascular disease (CVD) seen elevated in the serum of people living with HIV (PLWH) on HAART and in those with low cluster of differentiation-4 (CD4) cell counts. Thus, this study aimed to evaluate AIP and hsCRP levels among PLWH on dolutegravir (DTG) and ritonavir-boosted atazanavir-based (ATV/r) antiretroviral therapy (ART) and their correlations to CD4 cell counts. Methods: The study design was an institutional-based comparative cross-sectional study conducted from November 4, 2021, to January 4, 2022. The total sample size was 172 with equal number of DTG and ritonavir-boosted atazanavir-treated PLWH. Participants were recruited by a consecutive sampling method. The data were entered into EpiData Version 4.6, then exported to SPSS Version 25.0, and analyzed using Chi-square, Student's t-test, and Pearson correlation. Statistical significance was set at p < 0.05. Results: AIP was significantly higher among individuals on ATV/r, with levels in the range of 0.1-0.24 at 44.2% and > 0.24 at 31.4%, compared with those on DTG-based regimens of ART, which showed levels of 39.5% and 9.3%, respectively. Similarly, the higher hsCRP level of ≥ 2 mg/L was observed among patients on ATV/r (44.2%) than in DTG-based (24.4%) regimens of ART. AIP and hsCRP were negatively correlated with CD4 cell counts with Pearson correlation coefficients of -0.46 and -0.38, respectively. Conclusion: From the study conducted, it can be concluded that the higher levels of AIP and hsCRP were seen in patients treated by ATV/r than in DTG-based regimens of ART and in PLWH with low CD4 cell counts. Therefore, routine monitoring of both AIP and hsCRP levels was a good marker of HIV disease progression and cardiovascular disease risk assessment in PLWH, particularly in developing countries where CD4 cell count testing is expensive and not easily available.

Background: Depression in women living with HIV (WLWHIV), is one of the most common public health concerns worldwide. Depression has a negative impact on antiretroviral therapy (ART) adherence, quality of life, poor HIV treatment outcomes, and mortality. However, there is a paucity of evidence in low-income countries such as Ethiopia in WLWHIV. Objective: The aim of this study is to assess the magnitude of depression and related factors, and how social support mediates HIV-related stigma and depression in WLWHIV. Method: A cross-sectional study was conducted among 1043 patients in a health institution, employing a systematic random sampling technique to select the study participants. The structured Patient Health Questionnaire (PHQ-9), Oslo Social Support Scale, Perceived HIV-related stigma scale, Household Food Insecurity Access Scale (HFIAS), and Violence Against Women Scale were used to measure depression, social support, stigma, food insecurity, and intimate partner violence, respectively. Descriptive statistics were computed, and multivariate logistic regression and mediation analyses were conducted to identify factors associated with depression and how they mediate it. Results: The prevalence of depression among WLWHIV was 41.7% (95% CI: 38.7% and 44.5%). Being single (AOR = 1.80, 95% CI: 1.09-2.99), divorced (AOR = 1.56, 95% CI: 1.11-2.19), widowed (AOR = 1.93, 95% CI: 1.31-2.84), experiencing medical illness comorbidity (AOR = 2.74, 95% CI: 1.75-4.30), having a high viral load (AOR = 1.86, 95% CI: 1.00-3.45), receiving social support (AOR = 0.90, 95% CI: 0.84-0.96), experiencing perceived HIV-related stigma (AOR = 1.04, 95% CI: 1.02-1.06), experiencing food insecurity (AOR = 1.07, 95% CI: 1.03-1.11), and experiencing psychological violence (AOR = 2.05, 95% CI: 1.30-3.23) were significantly associated with depression. Social support partially mediated the relationship between perceived HIV-related stigma and depression. Conclusion: More than two of five WLWHIV developed depression. Depression is indirectly affected by perceived HIV-related stigma through social support. Social support enhances mental health well-being.

Background: Overweight and obesity have arisen as major public health challenges, affecting not just the general population but also people living with human immunodeficiency virus (HIV) (PLWH). Obesity and being overweight are both risk factors for heart disease and other related complications. However, little is known in our setting. As a result, this study was conducted to evaluate the prevalence of overweight and obesity and its associated factors among PLWH on dolutegravir (DTG)- and efavirenz (EFV)-based therapies. Methods: An institution-based comparative cross-sectional study was carried out from June 30, 2021, to August 30, 2021. We purposively recruited 128 participants who have been on DTG (n = 64)- and EFV (n = 64)-based regimens for ≥ 6 months. Demographic, anthropometric, laboratory, and clinical data were collected using a structured questionnaire. The data were entered into EpiData Version 4.6 and analyzed using SPSS Version 26.0. Multivariable logistic regression was utilized to identify the factors that are associated with being overweight or obese, and the significance level was set at p < 0.05. Result: The prevalence of overweight and obesity was 28.1% in the DTG-prescribed participants and 15.6% in the EFV-prescribed participants. Age ≥ 40 years (adjusted odd ratio (AOR) = 3.86; 95% confidence interval (CI): 1.08-13.73; and p=0.037), cluster of differentiation 4 (CD4) T-cell counts ≥ 500 cells/mm³ (AOR = 2.95; 95% CI: 1.01-8.59; and p=0.029), and insufficient physical activity (AOR = 4.6; 95% CI: 1.53-13.84; and p=0.007) were predictors of overweight and obesity. Conclusion: Overweight and obesity are not uncommon among PLWH on ART. While the difference was statistically insignificant, the prevalence of overweight and obesity was higher in patients treated with DTG compared with those treated with EFV. Older age, higher CD4 cell counts, and insufficient physical activity were associated with overweight and obesity. As a result, healthcare providers must understand the health implications of obesity and consider incorporating targeted weight control programs into standard HIV treatment.

Despite access to antiretroviral therapy (ART), South Africa has a high human immunodeficiency virus (HIV) burden. Treatment outcomes among individuals on highly active ART (HAART) in KwaZulu-Natal, with a higher incidence of HIV, are not fully known. This study evaluated the impact of HAART outcomes and identified and analyzed the factors associated with the outcomes in people living with HIV and AIDS (PLWHA) in the high-incidence region of KwaZulu-Natal Province, South Africa. This retrospective medical record review was conducted at King Edward VIII Hospital in South Africa. Data analysis was performed using STATA software Version 18.0 and Microsoft Excel 2021. The estimates used were 95% confidence intervals, and a p value < 0.05 was considered statistically significant. A total of 707 clinical records of PLWHA were examined and analyzed; less than half of them (44.98%, n = 318) achieved the benchmark of two consecutive instances of suppressed viral loads. The CD4 greater than or equal to 500 cells/mm³ at baseline average of 22.91% (n = 162) registered an increase to 48.94% (n = 346) in the 6^th month and further escalated to 79.49% (n = 562) by the 12^th month following ART initiation. A total of 160 deaths (mortality rate of 22.63%) were recorded within the study period. The percentage of HIV-infected patients attaining viral suppression at 6 and 12 months after initiating the treatment was respectively 44.98% and 67.04%, below the 90% target established by the Joint United Nations Program on HIV/AIDS (UNAIDS). The proportion of favorable immunological responses for individuals on ART increased over time.

Background: Following the 2018 World Health Organization's (WHO) guidelines on HIV treatment and management, the Zimbabwean government has embraced dolutegravir (DTG)-based regimens as the preferred first-line treatment for people living with HIV (PLWH). Despite this implementation, there remains a paucity of knowledge on the potential associations between DTG-based regimens, body weight and blood lipid levels among PLWH in Zimbabwe. Thus, the aim of this study was to investigate variances in body weight and blood lipid levels at two distinct timepoints-baseline and 6-month post-DTG initiation. Methods: We conducted this study between November 2021 and April 2023 among ART-naïve individuals initiating a DTG-based regimen. Participants were recruited from a tertiary clinic in Zimbabwe. Body weight, standing height and blood lipid levels were measured at baseline and 6-month post-DTG. Changes in weight, body mass index (BMI) and lipids levels were assessed using the paired Student's t-test and Wilcoxon signed rank test. Multivariable logistic and linear regression analysis was used to assess risk factors associated with changes in weight, BMI and lipid levels. Results: A cohort comprising 130 study participants, characterised by a mean (±SD) age of 40.0 (±11.0) years at baseline, was subjected to a 6-month regimen of DTG-based therapy. The outcomes revealed statistically significant alterations in various physiological parameters. Specifically, post the DTG-based intervention, there were substantial increases observed in body weight (p < 0.001), BMI (p=0.003), total cholesterol (TC) levels (p=0.002) and high-density lipoprotein cholesterol (HDL-C) levels (p < 0.001) in comparison to their baseline values. Intriguingly, the corresponding triglyceride (TG) levels exhibited a noteworthy decrease (p < 0.001). Notably, individuals aged 40 years or older exhibited a positive association (p=0.022) with increased TC levels and concurrent weight gain. Furthermore, current employment emerged as another factor positively linked to increased TC levels and weight gain. Conclusions: Upon the initiation of DTG, discernible elevations were observed in body weight, BMI and lipid levels. This study represents the first comprehensive assessment of lipid profiles and weight gain among this population in Zimbabwe, filling a critical gap in the existing literature. These findings, while indicative of short-term effects, underscore the imperative for further investigative efforts aimed at elucidating the prolonged consequences associated with DTG-induced weight gain and increased lipid levels and its underlying mechanisms.

Objectives: The primary objective of this study was to characterize women living with HIV (WLWH) in Belgium. The secondary objective was an exploratory analysis comparing women and men living with HIV (MLWH).

Methods: This was a cross-sectional, observational, multicenter study. Inclusion criteria for the primary objective were all adult treatment-naïve and experienced WLWH actively being treated at one of the participating centers. For the secondary objective, inclusion criteria were all adult naïve and experienced women and MLWH, actively being treated at a single participating center. Data were collected between December 2022 and March 2023. A multivariable analysis was performed on all women included to evaluate for associations with having hypertension (HTN) or being virologically nonsuppressed (HIV-1 VL ≥200 copies/mL). In the exploratory analysis of women and MLWH, a multivariable analysis was carried out to evaluate whether female gender was associated with having HTN or being virologically nonsuppressed.

Results: Overall, 2797 WLWH were included. The majority were Black (73.5%) and 48.5% were aged ≥50 years. The most common comorbidity was HTN (17.3%) and most individuals were virologically suppressed (HIV-1 VL <50 copies/mL; 85.6%). Black race was associated with having HTN (p < 0.0001). Prior AIDS-defining illness (p = 0.02) and a CD4⁺ T-cell count <500 cells/µL (p < 0.0001) were associated with being nonsuppressed. A total of 1094 WLWH and 1878 MLWH were included in the exploratory analysis. HTN was higher among WLWH (20.2% vs. 12% MLWH). Female gender was not found to be associated with having HTN (p = 0.86) or being nonsuppressed (p = 0.14).

Conclusion: In this analysis of WLWH in Belgium, the results depict an ageing population that is predominantly Black. The most common comorbidity observed was HTN. Women had a low rate of virologic nonsuppression, and female gender was not associated with being nonsuppressed.

Objectives: We aimed to study self-rated health and psycho-neuroimmunological responses during the initial 6 months after testing positive for human immunodeficiency virus (HIV) and its relationship to health literacy, that is, the ability to take in and understand information about one's illness. Health literacy plays a critical role in patients' ability to adhere to antiretroviral treatment (ART). However, there is a lack of studies on the possible impact of HIV-induced proinflammatory processes on health literacy.

Methods: Twelve patients with newly diagnosed HIV attending an urban Ryan White-funded HIV clinic responded to a questionnaire and had blood samples drawn at baseline (first visit) and after 1, 3, and 6 months, respectively. The questionnaire measured stress, depression, and health literacy. Blood was analyzed for HIV RNA plasma viral load, CD4 cell count, pro- and antistress, and inflammatory markers.

Results: Complete data for the entire 4 collection periods were available for nine patients. Over the 6-month period, mean viral load decreased from 353,714.83 (standard deviation 870,334.61) to 35.89 (14.04) copies/mL (p < 0.001). CD4 cell count increased from 321.08 (167.96) to 592.44 (300.06) cells/mm³ (p < 0.001). Self-rated stress decreased from a baseline mean of 7.33 (2.29) to 3.56 (3.21), on a 0-10 visual analogue scale, at the 6-month follow-up (p < 0.01). C-reactive protein (CRP) decreased from 5757.05 (3146.86) to 2360.84 (2277.33) ng/mL (p < 0.05). Mean health literacy score at baseline was 17.67 (3.50; scale range 0-20) and did not change during the follow-up period. However, increased stress and decreased CRP (p = 0.05) during the 6-month follow-up predicted higher health literacy scores at 6 months.

Conclusion: Both stress and proinflammatory processes in newly diagnosed HIV-infected patients might adversely impact patients' health literacy and thus their capacity to align with treatment guidance.

Introduction: Though people living with HIV/AIDS require a good combination of antiretroviral therapy and healthy dietary habits for a quality life and positive medical outcomes, little is, however, known regarding the dietary practices of HIV-positive patients who receive antiretroviral therapy (ART) in the Lawra Municipality.

Objective: This study assessed the magnitude and factors associated with dietary diversity among HIV-positive patients on antiretroviral therapy (ART).

Methods: This study was a facility-based cross-sectional study of 269 study participants recruited using a systematic random sampling technique. Bivariate and multivariable logistic regression analyses were performed to identify factors associated with their dietary diversity.

Results: This study shows that only 36 (13.4%) of the sample consumed a diversified diet with a mean dietary diversity score of 3.7 ± 0.99. Starchy staple foods (96.7%) and flesh food (92.9%) were the most consumed foods. Being a nonfarmer employee (AOR = 10.76, 95% CI = 1.03-112.35), not taking cotrimoxazole prophylaxis (AOR = 3.76, 95% CI = 1.02-14.37) and adults of age 18-27 years (AOR = 5.95, 95% CI = 1.18-30.07) were significant predictors of high dietary diversity.

Conclusion: This study revealed that dietary diversity was a significant nutritional problem among HIV-positive adults in Lawra Municipal Hospital. Starchy staple foods and flesh food were the most consumed foods, while organ meats, dairy products, and eggs were eaten less. Having a secured salary paid job, not taking cotrimoxazole prophylaxis, and being a young adult were strong predictors of a high dietary diversity score. Therefore, efforts should be made to strengthen and improve the economic status and to educate these vulnerable groups on the need to adhere to cotrimoxazole prophylaxis uptake.
