Risk of diabetes mellitus in HIV-infected patients receiving highly active antiretroviral therapy: A nationwide population-based study

Diabetes mellitus and associated factors among HIV-positive patients at primary health care facilities in Harare, Zimbabwe: a descriptive cross-sectional study

BACKGROUND

Highly active antiretroviral therapy (HAART) has improved the life expectancy of people living with HIV (PLWH) and has increased the risk of chronic non-communicable diseases. Comorbid HIV and diabetes mellitus (DM) significantly increase cardiovascular disease and mortality risk. This study aimed to determine the prevalence of type 2 diabetes mellitus among HIV-positive patients receiving HAART in Zimbabwe and its associated risk factors.

METHODS

This cross-sectional study was conducted at eight primary healthcare facilities in Harare, Zimbabwe, between January 2022 and March 2023. Non-probability convenience sampling was used to recruit adult HIV-positive patients undergoing HAART attending the facilities. Data were captured on clinical history and socio-demographic and behavioral characteristics, and analyzed using descriptive statistics to determine DM prevalence rates. Additionally, bivariate and multivariate logistic regression models were employed to examine factors associated with HIV and DM comorbidities.

RESULTS

A total of 450 participants were included in this study, of which 57.6% (n = 259) were female. The majority were married (73.8%) and older than 35 years (80.2%). Most participants had completed high school (87.6%) and 68.9% were employed either formally or self-employed. The prevalence of diabetes mellitus (DM) was 14.9%. HIV/DM comorbidity was more prevalent in patients who were female, self-employed, and smoked (p < 0.05). Multivariate logistic regression analysis revealed that the factors associated with DM-HIV comorbidity were gender, age, education, marital status, employment status, smoking, physical activities, duration of HAART, and diet. Age, level of education, marital status, and occupation were not associated with HIV-DM comorbidity. Obesity (body mass index > 30 kg/m2), smoking, and alcohol consumption were associated with an increased risk of DM. Regular physical activity is associated with a reduced risk of DM.

CONCLUSION

A substantial burden of DM was found in PLWH. The intersectoral integration approach is advocated, and active screening for DM is recommended. Gender-specific interventions are necessary to target diseases and health behaviors that differ between men and women. These interventions should be customized to the specific diseases and behaviors of each group.

Evidence gaps on weight gain in people living with HIV: a scoping review to define a research agenda

BACKGROUND

Combined antiretroviral therapy (cART) dramatically improved survival in people living with HIV (PLWH) but is associated with weight gain (WG), raising concern for a possible obesity epidemic in PLWH. This scoping review aims to identify the gaps in the existing evidence on WG in PLWH and generate a future research agenda.

METHODS

This review was conducted according to the methodology for scoping studies and reported according to the PRISMA Extension for Scoping Review checklist. Articles published in English in the last 10 years indexed in Pubmed, WHO Global Index Medicus, or Embase were searched using specific queries focused on WG in PLWH.

RESULTS

Following the selection process, 175 included articles were reviewed to search for the available evidence on four specific topics: (I) definition of WG in PLWH, (II) pathogenesis of WG in PLWH, (III) impact of ART on WG, (IV) correlation of WG with clinical outcomes. A summary of the data enabled us to identify gaps and clearly define the following research agenda: (I) develop a data-driven definition of WG in PLWH and define noninvasive assessment methods for body weight and fat composition; (II) further investigate the interaction between HIV/cART and immunity, metabolism, and adipose tissue; (III) establish the specific role of individual drugs on WG; (IV) clarify the independent role of WG, cART, HIV, and metabolic factors on clinical events.

CONCLUSIONS

The proposed research agenda may help define future research and fill the knowledge gaps that have emerged from this review.

Highly active antiretroviral therapy-silver nanoparticle conjugate interacts with neuronal and glial cells and alleviates anxiety-like behaviour in streptozotocin-induced diabetic rats

The inception of highly active antiretroviral therapy (HAART) has changed the management of human immunodeficiency virus (HIV) positive patients, with an improvement in life expectancy. However, neurological complications associated with high dosage and chronic administration of HAART have not been fully addressed. Therefore, this study evaluated the potential benefits of silver nanoparticles (AgNPs) conjugated-HAART (HAART-AgNPs) and its interaction with neuronal and glial cells in type-2 diabetic rats. Forty-two (n = 42) adult male Sprague-Dawley rats (250 ± 13 g) were divided into non-diabetic and diabetic groups. Each rat was administered with either distilled water, HAART, or HAART-AgNPs for eight weeks. After that, the prefrontal cortex (PFC) was excised for immunohistochemical, biochemical, and ultrastructural analysis. The formulated HAART-AgNPs were characterised by Ultraviolet-Visible, Transmission electron microscope, Energy Dispersive X-ray and Fourier transform infrared spectroscopy. Of the various concentrations of HAART-AgNPs, 1.5 M exhibited 20.3 nm in size and a spherical shape was used for this study. Administration of HAART-AgNPs to diabetic rats significantly decreased (p < 0.05) blood glucose level, number of faecal pellets, malondialdehyde (MDA), tumour necrosis factor-alpha (TNF-α), Interleukin-1 beta (IL-1β) compared with HAART-treated diabetic rats. Notably, there was a significant increase (p < 0.05) in antioxidant biomarkers (SOD and GSH), improvement in PFC-glial fibrillary acid protein (PFC-GFAP) positive cells and alleviation of anxiety-like behaviour in HAART-AgNPs treated diabetic rats. These results showed that HAART-AgNPs alleviates the anxiogenic effect and neuronal toxicity aggravated by HAART exposure via the reduction of oxidative and neuroinflammatory injury as well as preserving PFC GFAP-positive cells and neuronal cytoarchitecture.

Nanodelivery of antiretroviral drugs to nervous tissues

Despite the development of effective combined antiretroviral therapy (cART), the neurocognitive impairments associated with human immunodeficiency virus (HIV) remain challenging. The presence of the blood-brain barrier (BBB) and blood-cerebrospinal fluid barrier (BCFB) impedes the adequate penetration of certain antiretroviral drugs into the brain. In addition, reports have shown that some antiretroviral drugs cause neurotoxicity resulting from their interaction with nervous tissues due to long-term systemic exposure. Therefore, the research into the effective therapeutic modality that would cater for the HIV-associated neurocognitive disorders (HAND) and ART toxicity is now receiving broad research attention. Thus, this review explores the latest information in managing HAND using a nanoparticle drug delivery system (NDDS). We discussed the neurotoxicity profile of various approved ART. Also, we explained the applications of silver nanoparticles (AgNPs) in medicine, their different synthesis methods and their interaction with nervous tissues. Lastly, while proposing AgNPs as useful nanoparticles in properly delivering ART to enhance effectiveness and minimize neurocognitive disorders, we hypothesize that the perceived toxicity of AgNPs could be minimized by taking appropriate precautions. One such precaution is using appropriate reducing and stabilizing agents such as trisodium citrate to reduce silver ion Ag + to ground state Ag0 during the synthesis. Also, the usage of medium-sized, spherical-shaped AgNPs is encouraged in AgNPs-based drug delivery to the brain due to their ability to deliver therapeutic agents across BBB. In addition, characterization and functionalization of the synthesized AgNPs are required during the drug delivery approach. Putting all these factors in place would minimize toxicity and enhance the usage of AgNPs in delivering therapeutic agents across the BBB to the targeted brain tissue and could cater for the HIV-associated neurocognitive disorders and neurotoxic effects of antiretroviral drugs (ARDs).

Efficacy and Safety of a Simplified Lamivudine Plus Dolutegravir Dual Therapy in HIV-1-Infected Patients: A Multicenter Cohort Study in China

BACKGROUND

Results from both clinical trials and real-world observational studies suggest that lamivudine plus dolutegravir (3TC + DTG) dual therapy has excellent virological efficacy and safety in HIV-1-infected patients. However, there is still no relevant study related to this dual therapy reported in China.

METHODS

In this multicenter, retrospective, observational study that included HIV-1-infected patients in China, baseline and follow-up data were collected to analyze the virological suppression rate, immune restoration, and adverse events during follow-up in HIV-1-infected patients who switched to the 3TC + DTG dual therapy.

RESULTS

This study recruited 112 HIV-1-infected patients, including 101 men (90.2%), with a median age of 44.0 years (IQR: 33.00-57.75) and median CD4+ T-cell count of 432.13 cells/μL (IQR: 237.75-578.50). The overall virological suppression rate was 94.5% at the 24-week follow-up. However, the virological suppression rates of men who have sex with men patients and patients with CD4+ T-cell count of <350 cells/μL were higher than the baseline value (P < 0.05) at week 24. The results of Cox regression analysis showed that the baseline CD4+ T-cell count was an independent determinant of immune restoration in patients, and patients with baseline CD4+ T-cell count of 350-500 cells/μL outperformed patients with baseline CD4+ T-cell count of <350 cells/μL in immune restoration (hazard ratio: 4.469, 95% confidence interval: 1.801 to 11.091, P = 0.001). Adverse events were reported in 5 patients (incidence rate of 4.5%); among them, 3 patients developed neuropsychiatric symptoms. Results from the laboratory data analysis showed that patients with grade 1 and 2 adverse events had elevated levels of low-density lipoprotein cholesterol and total bilirubin. Furthermore, grade 3 and 4 adverse events were associated with the elevation of blood glucose level in 4 patients.

CONCLUSIONS

Thus, the 3TC + DTG dual therapy displayed an excellent virological efficacy against HIV-1 infections and had an acceptable safety profile, with predominantly mild adverse events in HIV-1-infected patients in China.

Studies on testicular ultrastructural and hormonal changes in type-2 diabetic rats treated with highly active antiretroviral therapy conjugated silver nanoparticles

AIM

This study investigated the impact of highly active antiretroviral therapy (HAART) loaded silver nanoparticles (AgNPs) as HAART-AgNPs on the sperm count, viability, serum hormonal profile, insulin-like growth factor I (IGF-1), and testicular ultrastructure.

METHODS

Thirty-six adult male Sprague-Dawley rats were allocated into diabetic and non-diabetic groups (n = 18). The rats in the diabetic group were induced experimental type 2 diabetes using fructose and streptozotocin (frt-STZ). Animals in both groups were subdivided into three groups each, A-C and DF (n = 6), and received distilled water, HAART, and HAART-AgNP, respectively.

FINDINGS

Treatment with HAART-AgNP displayed a significant increase (p < 0.05) in serum gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testicular IGF-1 in diabetic rats. Also, electron microscopy revealed ameliorated testicular ultrastructure upon administration of HAART-AgNP in diabetic rats that were previously marked with architectural and cellular alterations. In addition, treatment with HAART-AgNP significantly reduced (p < 0.05) the blood glucose levels of diabetic rats. In contrast, the treatment of non-diabetic rats with HAART caused a significant decrease (p < 0.05) in the sperm count, serum GnRH, and testicular IGF-1, however, this treatment induced ultrastructural changes and a significant increase (p < 0.05) in serum testosterone levels in diabetic and non-diabetic rats.

SIGNIFICANCE

This study has demonstrated the beneficial impact of HAART-AgNP on the hypothalamic-pituitary-gonadal axis, IGF-1, and testicular architecture in male frt-STZ induced diabetic rats. This nanoconjugate could be a potential nano-drug candidate to cater for testicular dysfunction and metabolic derangements while managing HIV-infected male individuals.

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.

Silver Nanoparticles Conjugate Attenuates Highly Active Antiretroviral Therapy-Induced Hippocampal Nissl Substance and Cognitive Deficits in Diabetic Rats

BACKGROUND

The application of nanomedicine to antiretroviral drug delivery holds promise in reducing the comorbidities related to long-term systemic exposure to highly active antiretroviral therapy (HAART). However, the safety of drugs loaded with silver nanoparticles has been debatable. This study is aimed at evaluating the effects of HAART-loaded silver nanoparticles (HAART-AgNPs) on the behavioural assessment, biochemical indices, morphological, and morphometric of the hippocampus in diabetic Sprague-Dawley rats.

METHODS

Conjugated HAART-AgNPs were characterized using FTIR spectroscopy, UV spectrophotometer, HR-TEM, SEM, and EDX for absorbance peaks, size and morphology, and elemental components. Forty-eight male SD rats (250 ± 13 g) were divided into nondiabetic and diabetic groups. Each group was subdivided into (n = 8) A (nondiabetic+vehicle), B (nondiabetic+HAART), C (nondiabetic+HAART-AgNPs), D (diabetic+vehicle), E (diabetic+HAART), and F (diabetic+HAART-AgNPs). Morris water maze, Y-maze test, and weekly blood glucose levels were carried out. Following the last dose of 8-week treatment, the rats were anaesthetized and euthanized. Brain tissues were carefully removed and postfixed for Nissl staining histology.

RESULTS

1.5 M concentration of HAART-AgNPs showed nanoparticle size 20.3 nm with spherical shape. HAART-AgNPs revealed 16.89% of silver and other elemental components of HAART. The diabetic control rats showed a significant increase in blood glucose, reduced spatial learning, positive hippocampal Nissl-stained cells, and a significant decrease in GSH and SOD levels. However, administration of HAART-AgNPs to diabetic rats significantly reduced blood glucose level, improved spatial learning, biochemical indices, and enhanced memory compared to diabetic control. Interestingly, diabetic HAART-AgNP-treated rats showed a significantly improved memory, increased GSH, SOD, and number of positive Nissl-stained neurons compared to diabetic-treated HAART only.

CONCLUSION

Administration of HAART to diabetic rats aggravates the complications of diabetes and promotes neurotoxic effects on the experimental rats, while HAART-loaded silver nanoparticle (HAART-AgNP) alleviates diabetes-induced neurotoxicity.

Weight Gain and Related Comorbidities Following Antiretroviral Initiation in the 2000s: A Systematic Literature Review

Antiretroviral therapies (ARTs) benefit millions with human immunodeficiency virus. However, concerns about subsequent weight gain and related metabolic complications have emerged. Early ARTs are associated with adipose tissue changes. While newer ARTs may have fewer adipose alterations, it is unclear whether they lead to increased weight gain. A systematic literature review was performed to describe current published literature describing the use of newer ARTs, weight gain, and related comorbidities. Titles and abstracts were screened, focusing on studies that examined ART initiation and subsequent weight gain; publications were then ranked based on publication type, methodology, and comorbidities, emphasizing US studies with large patient cohorts. This yielded a comprehensive review of the 50 publications on weight gain and a range of related comorbidities, including diabetes and hypertension. Most of the studies describing weight gain found the most significant gains during the first year after initiating ART. Overall, patients gained ∼5 kg 18-96 months after initiating ART. Many of the studies reported altered weight-related comorbidities, including increased risk of diabetes and hypertension. Despite an expectation that newer ARTs may be safer, a review of the literature suggests that contemporary ART use is associated with pronounced weight gain and related comorbidities. Future studies should define and quantify the direct role of newer ARTs in weight gain and related comorbidities, as well as clarify the role of specific drug classes in metabolic disturbance, to improve intervention strategies.

The impact of physician subspeciality on the quality of diabetes care for people living with HIV

BACKGROUND

Management of comorbidities of people living with HIV (PLHIV) involves different care models, including providing diabetes care and HIV care by the same infectious diseases physician (IDP) ("consolidated care") or providing diabetes care by the physicians other than IDP ("shared care"). The impact of diabetes care model on PLHIV with diabetes mellitus (DM) has not been well-evaluated.

METHODS

A nationwide cross-sectional sample in the Taiwan National Health Insurance Research Database was used to compare the performance rates of seven guideline-recommended tests provided by the different subspecialists.

RESULTS

Of 523 PLHIV with DM, there were 54.88% (n = 287) in the consolidated care group and 45.12% (n = 236) in the shared care group. More patients in the consolidated care group received the tests of lipid profile (92.33% vs. 79.24%), creatinine (Cr) (93.73% vs. 78.39%), and alanine transaminase (ALT) (91.99% vs. 75.42%), but fewer received urine protein test (35.54% vs. 51.69%) and fundoscopic examination (8.01% vs. 33.90%). The two groups did not differ in the performance rates of serum fasting glucose and HbA1c. After controlling for demographic factors and diabetic severity, the consolidated group was less likely to miss the serum tests of lipid profile (odds ratio [OR]: 0.30), Cr (OR: 0.19), and ALT (OR: 0.23), but more often missed urine protein test (OR: 1.56) and fundoscopic examination (OR: 4.97).

CONCLUSION

These findings suggest the need to focus on different process indicators of diabetes cares in different care models to enhance the diabetes care for PLHIV.

Trends of age-related non-communicable diseases in people living with HIV and comparison with uninfected controls: A nationwide population-based study in South Korea

OBJECTIVES

We aim to compare the trends of non-communicable diseases (NCDs) and death among people living with HIV (PLWH) and uninfected controls in South Korea.

METHODS

We identified PLWH from a nationwide database of all Korean citizens enrolled from 1 January 2004 to 31 December 2016. A control cohort was randomly selected for PLWH by frequency matching for age and sex in a 20:1 ratio. To compare NCD trends between the groups, adjusted incidence rate ratios for outcomes across ages, calendar years and times after HIV diagnosis were calculated.

RESULTS

We included 14 134 PLWH and 282 039 controls in this study; 58.5% of PLWH and 36.4% of the controls were diagnosed with at least one NCD. The incidence rates of cancers, chronic kidney disease, depression, osteoporosis, diabetes and dyslipidaemia were higher in PLWH than in the controls, whereas those of cardiovascular disease, heart failure, ischaemic stroke and hypertension were lower in PLWH. Relative risks (RRs) for NCDs in PLWH were higher than controls in younger age groups. Trends in the RRs of NCDs tended to increase with the calendar year for PLWH vs. controls and either stabilized or decreased with time after HIV diagnosis. The RR of death from PLWH has decreased with the calendar year, but showed a tendency to rise again after 2014 and was significant at the early stage of HIV diagnosis.

CONCLUSIONS

Although the RR of each NCD in PLWH showed variable trends compared with that in controls, NCDs in PLWH have been increasingly prevalent.

Metabolic Syndrome Prevalence and Cardiovascular Risk Assessment in HIV-Positive Men with and without Antiretroviral Therapy

Treatment of HIV infection is a lifelong process and associated with chronic diseases. We evaluated the prevalence and predictors of metabolic syndrome (MetS) and cardiovascular diseases (CVDs) with individual antiretroviral drugs exposure among HIV-infected men in Taiwan. A total of 200 patients’ data were collected with a mean age of 32.9. Among them, those who had CD4 positive cell number less than 350/mL were eligible to have highly active antiretroviral therapy (HAART). Patients were divided into group-1 that contains 45 treatment-naïve participants, and group-2 that includes 155 HAART treatment-experienced participants. MetS prevalence between group-1 and group-2 was 18% and 31%, respectively. The Framingham Risk Score (FRS) for the naïve and experienced groups were 4.7 ± 4.2 and 3.87 ± 5.92, respectively. High triglyceride (TG > 150 mg/dL) in group-1 and group-2 were 15.6% and 36.6% (p < 0.05), whereas, lower high-density lipoprotein (HDL < 39 mg/dL) in group-1 and group-2 presented as 76.7% versus 51% (p < 0.05), respectively. In group-2, treatment with protease inhibitors (PIs) resulted in higher TG levels when compared with non-nucleotide reverse transcriptase inhibitors (NNRTIs) and integrase inhibitors (InSTIs). The prevalence of MetS in the treatment-naïve group was lower than that of the treatment-experienced group; high TG level resulted in higher MetS prevalence in the treatment-experienced group. In contrast, the cardiovascular risk of FRS in the treatment-naïve group was higher than that of the treatment-experienced group, which may result from the low HDL level. Although group-1 participants have a higher risk of developing CVDs, in group-2, an increasing TG level in PIs user indicated higher CVDs risk. TG and HDL are two significant biofactors that required regular evaluation in HIV-positive individuals.

Cardiovascular Risk Assessment in HIV-Infected Patients

From the onset of the first case until now, HIV infection is one of the most studied pathologies in the medical field, due to the incompletely known action of the virus per se, as well as the comorbidities associated with it. Currently, a field of interest in research is occupied by cardiovascular comorbidities, being more and more frequent at PLWH. From the pathophysiological mechanisms of action, the traditional and modern CV risk factors, the scores with relative predictability to the adverse effects of ARV therapy, CVD at PLWH represent an incomplete studied field, which requires further investigation.

Effectiveness and safety of dolutegravir two-drug regimens in virologically suppressed people living with HIV: a systematic literature review and meta-analysis of real-world evidence

Objectives

Dolutegravir (DTG) is widely recommended within three‐drug regimens. However, similar efficacy and tolerability have also been achieved with DTG within two‐drug regimens in clinical trials. This study evaluated the real‐world effectiveness and discontinuations in people living with HIV‐1 (PLHIV) switching to DTG with lamivudine (3TC) or rilpivirine (RPV).

Methods

This was a one‐arm meta‐analysis utilizing data from a systematic literature review. Data from real‐world evidence studies of DTG + RPV and DTG + 3TC were extracted, pooled and analysed. The primary outcome was the proportion of patients with viral failure (VF; ≥ 50 copies/mL in two consecutive measurements and/or ≥ 1000 copies/mL in a single measurement) at week 48 (W48) and week 96 (W96). Other outcomes included virological suppression (VS; < 50 copies/mL) and discontinuations (W48 and W96). Estimates were calculated for VF, VS as per snapshot (VSS) and on treatment analysis (VSOT), and discontinuations.

Results

Pooled mean estimates of VF for DTG + 3TC and DTG + RPV were 0.8% [95% confidence interval (CI): 0.4–1.3] and 0.6% (95% CI: 0.0–1.6), respectively, at W48. VSS rate at W48 was 85.0% (95% CI: 82.3–87.5) for DTG + 3TC regimen and 92.4% (95% CI: 85.0–97.7) in the DTG + RPV regimen. The DTG + 3TC and DTG + RPV regimens led to discontinuations in 13.6% (95% CI: 11.1–16.2) and 7.2% (95% CI: 2.1–14.4) of patients, respectively, at W48. Similar results were observed at W96.

Conclusions

Treatment with DTG + 3TC or DTG + RPV in clinical practice provides a low rate of VF and a high rate of VS when initiated in virologically suppressed PLHIV with diverse backgrounds.

The Increase of HIV-1 Infection, Neurocognitive Impairment, and Type 2 Diabetes in The Rio Grande Valley

The Human Immunodeficiency Virus (HIV-1) infection remains a persistent predicament for the State of Texas, ranking seventh among the most documented HIV cases in the United States. In this regard, the Rio Grande Valley (RGV) in South Texas is considered as one of the least investigated areas of the state with respect to HIV infection and HIV associated comorbidities. Considering the 115% increase in average HIV incidence rates per 100,000 within the RGV from 2007-2015, it is worth characterizing this population with respect to their HIV-1 infection, HIV-1 Associated Neurocognitive Disorders (HAND), and the association of treatment with combined antiretroviral therapy (cART). Moreover, the increased rate of Type-2 Diabetes (T2D) in the RGV population is intertwined with that of HIV-1 infection facing challenges due to the lack of knowledge about prevention to inadequate access to healthcare. Hence, the role of T2D in the development of HAND among the people living with HIV (PLWH) in the RGV will be reviewed to establish a closer link between T2D and HAND in cART-treated patients of the RGV.

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.

Diabetes Mellitus and Associated Factors Among Adult HIV Patients on Highly Active Anti-Retroviral Treatment

BACKGROUND

Highly active anti-retroviral therapy (HAART) prolongs the life span of people living with HIV (PLWHIV) and intensely reduces HIV-related morbidity and mortality. Globally, HIV-associated non-communicable diseases are becoming major public concerns, and chronic comorbidities have appeared as a substantial reason for morbidity and mortality in HIV patients with prolonged use of HAART.

PURPOSE

A cross-sectional study design was used to assess the magnitude of diabetes mellitus and risk factors among adult HIV patients exposed to HAART at Jimma Zone Public Hospitals from May to July 30, 2018.

PATIENTS AND METHODS

A convenient sampling technique was used to include a total of 271 adult HIV patients on HAART visiting the selected health facilities at the time of data collection. Socio-demographic and clinical data were collected by interviewer-administered questionnaire and by reviewing patients' record data. Bivariate and multivariate logistic regressions were used to identify variables that are independent predictors for diabetes mellitus.

RESULTS

The prevalence of diabetes and pre-diabetes among PLWHIV exposed to HAART was 11.4% and 16.6%, respectively. The prevalence of diabetic dyslipidemia in PLWHIV exposed on HAART was 8.9% (n=24). Government workers (AOR: 0.17, 95% C.I=0.03-0.85, P=0.031), long duration in HAART use (AOR: 11.06, 95% C.I:1.03-18.67, P=0.047), hyper-triglyceridemia (AOR: 2.62,95% C.I:0.82, 8.39, P=0.005), LDL-C <130 mg/dl (AOR: 4.04, 95% C.I=1.33-12.30, P=0.014), and obesity (AOR: 9.62, 95% C.I: 1.01-91.52, P=0.049) were independent risk factors for diabetes mellitus in PLWHIV exposed to HAART.

CONCLUSION

Exposure to HAART increased the prevalence of diabetes mellitus in PLWHIV although it enhances quality of life, improves immune functions and prevents the onset of opportunistic infections. Therefore, regular screening for blood glucose level for PLWHIV on HAART is advisable.

Combined Tuberculosis and Diabetes Mellitus Screening and Assessment of Glycaemic Control among Household Contacts of Tuberculosis Patients in Yangon, Myanmar

Background: This study aimed to identify the prevalence of diabetes mellitus (DM) and tuberculosis (TB) among household contacts of index TB patients in Yangon, Myanmar. Method: Household contacts were approached at their home. Chest X-ray and capillary blood glucose tests were offered based on World Health Organization and American Diabetes Association guidelines. Crude prevalence and odds ratios of DM and TB among household contacts of TB patients with and without DM were calculated. Results: The overall prevalence of DM and TB among household contacts were (14.0%, 95% CI: 10.6–18.4) and (5%, 95% CI: 3.2–7.6), respectively. More than 25% of DM cases and almost 95% of TB cases among household contacts were newly diagnosed. Almost 64% of known DM cases among household contacts had poor glycaemic control. The risk of getting DM among household contacts of TB patients with DM was significantly higher (OR—2.13, 95% CI: 1.10–4.12) than those of TB patients without DM. There was no difference in prevalence of TB among household contacts of TB patients with and without DM. Conclusion: Significant proportions of the undetected and uncontrolled DM among household contacts of index TB patients indicate a strong need for DM screening and intervention in this TB–DM dual high-risk population.

Impact of diabetes on the risk of serious liver events and liver-related deaths in people living with HIV and hepatitis C co-infection: data from the ICONA Foundation Cohort Study

To investigate the association between diabetes and HCV infection in persons living with HIV and to determine the impact of diabetes on the occurrence of serious liver events (SLEs) and liver-related deaths (LRDs) among HIV/HCV-co-infected patients. Patients were included if they had at least one follow-up visit. In a cross-sectional analysis among all HIV patients, we have investigated the association between diabetes and HCV infection. A further longitudinal analysis was performed in the population of HIV/HCV-co-infected free from SLE with FIB-4 index < 3.25 at baseline, using the following endpoints: (A) first event between SLE and LRD; (B) liver fibrosis progression defined as the first of two consecutive FIB-4 > 3.25; (C) first event between SLE, LRD, and liver fibrosis progression. Data from 15,571 HIV patients were analyzed: 2944 (18.9%) were HCV-Ab positive, and 739 (4.7%) presented a diagnosis of diabetes at their last follow-up. Among HIV/HCV-co-infected population, 107 patients had a diagnosis of diabetes. Viremic HCV-co-infected patients had 3-fold risk of diabetes onset than HCV-uninfected patients. On HIV/HCV-co-infected population, 85 SLEs/LRDs occurred over 20,410 person-years of follow-up (PYFU), for an incidence rate of 4.2/1000 PYFU (95%CI 3.4-5.2). Diabetic patients had 3-fold risk of pooled SLE and LRD than patients without diabetes. Furthermore, viremic HCV infection was independently associated with a higher risk of SLE/LRD (aIRR 3.35 [95%CI 1.14-9.83]). In HIV-infected patients, viremic HCV co-infection is a strong predictor of diabetes. Among HIV/HCV-co-infected population, diabetic patients showed an increased risk of SLE/LRD compared with those without diabetes.
