Abstract
Metabolic syndrome (MetS) poses a significant clinical challenge for individuals living with HIV (PLHIV). In sub-Saharan Africa (SSA), this condition is becoming a growing concern, owing to lifestyle changes and an increasingly aging population. Several SSA countries have reported on the prevalence of MetS. However, these estimates may be outdated because numerous recent studies have updated MetS prevalence among PLHIV in these countries. Moreover, prior research has focused on various study designs to report the pooled prevalence, which is a methodological limitation. Therefore, this systematic review and meta-analysis aimed to determine the pooled estimates of MetS in PLHIV in SSA by addressing these gaps. We systematically searched Google Scholar, Science Direct, Scopus, Web of Sciences, EMBASE, and PubMed/Medline for the prevalence of MetS and its subcomponents among people with HIV in sub-Saharan Africa. The estimated pooled prevalence was presented using a forest plot. Egger's and Begg's rank regression tests were used to assess evidence of publication bias. Twenty-five studies fulfilled the inclusion criteria after review of the updated PRISMA guidelines. The pooled prevalence of MetS was 21.01% [95% CI: (16.50, 25.51)] and 23.42% [95% CI: (19.16, 27.08)] to the National Cholesterol Education Program Adult Treatment Panel III (NCEP/ATP III) and International Diabetes Federation (IDF) criteria, respectively. Low levels of high-density lipoprotein cholesterol (Low HDL) at 47.25% [95% CI: 34.17, 60.33)] were the highest reported individual subcomponent, followed by abdominal obesity at 38.44% [95% CI: (28.81, 48.88)]. The prevalence of MetS is high in sub-Saharan Africa. Low HDL levels and increased waist circumference/abdominal obesity were the most prevalent components of MetS. Therefore, early screening for MetS components and lifestyle modifications is required. Policymakers should develop strategies to prevent MetS before an epidemic occurs.PROSPERO: CRD42023445294.

Prevalence of the metabolic syndrome in African populations: A systematic review and meta-analysis. PLoS One 2023; 18:e0289155. [PMID: 37498832 PMCID: PMC10374159 DOI: 10.1371/journal.pone.0289155] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Accepted: 07/12/2023] [Indexed: 07/29/2023] Open
Abstract
BACKGROUND The metabolic syndrome (MS) is a leading cause of death worldwide. Several studies have found MS to be prevalent in various African regions. However, no specific estimates of MS prevalence in African populations exist. The aim of this study was to estimate the overall prevalence of MS in the African populations. METHODS A systematic review was conducted in PubMed, Web of Science, Africa Index Medicus, and African Journal Online Scopus to find studies published up to the 15th of August 2022. Pooled prevalence was calculated based on six diagnostic methods. The pooled prevalence of MS was estimated using a random-effects model. Our risk of bias analysis was based on the Hoy et al. tool. A Heterogeneity (I2) assessment was performed, as well as an Egger test for publication bias. PROSPERO number CRD42021275176 was assigned to this study. RESULTS In total, 297 studies corresponding to 345 prevalence data from 29 African countries and involving 156 464 participants were included. The overall prevalence of MS in Africa was 32.4% (95% CI: 30.2-34.7) with significant heterogeneity (I2 = 98.9%; P<0.001). We obtained prevalence rates of 44.8% (95% CI: 24.8-65.7), 39.7% (95% CI: 31.7-48.1), 33.1% (95% CI: 28.5-37.8), 31.6% (95% CI: 27.8-35.6) and 29.3% (95% CI: 25.7-33) using the WHO, revised NCEP-ATP III, JIS, NCEP/ATP III and IDF definition criteria, respectively. The prevalence of MS was significantly higher in adults >18 years with 33.1% (95%CI: 30.8-35.5) compared to children <18 years with 13.3% (95%CI: 7.3-20.6) (P<0.001). MS prevalence was significantly higher in females with 36.9% (95%CI: 33.2-40.7) compared to males with 26.7% (95%CI: 23.1-30.5) (P<0.001). The prevalence of MS was highest among Type 2 diabetes patients with 66.9% (95%CI: 60.3-73.1), followed by patients with coronary artery disease with 55.2% (95%CI: 50.8-59.6) and cardiovascular diseases with 48.3% (95%CI: 33.5-63.3) (P<0.001). With 33.6% (95% CI: 28.3-39.1), the southern African region was the most affected, followed by upper-middle income economies with 35% (95% CI: 29.5-40.6). CONCLUSION This study, regardless of the definition used, reveals a high prevalence of MS in Africa, confirming the ongoing epidemiological transition in African countries. Early prevention and treatment strategies are urgently needed to reverse this trend.

Abstract
While human immunodeficiency virus (HIV)-associated wasting has declined with significant advances in antiretroviral therapy (ART), weight gain and metabolic syndrome (MetS) are now becoming a problem for people living with HIV (PLWH) worldwide. The development of a new and more effective ART regimen has increased viral suppression and improved immunologic function recovery, leading to the extension of the lifespan of PLWH. It has recently been reported as one of the significant factors associated with weight gain, obesity, and long-term metabolic consequences in PLWH. This article reviewed the epidemiology of overweight and MetS among PLWH and the known risk factors for weight gain and its major comorbidities, such as dyslipidemia, diabetes mellitus, cardiovascular diseases, neurocognitive disorders, and liver diseases, in PLWH. In addition, reports on the pharmacological and surgical management of overweight and obesity in PLWH has been briefly summarized.

Fiseha T, Gebreweld A. Renal function in a cohort of HIV-infected patients initiating antiretroviral therapy in an outpatient setting in Ethiopia. PLoS One 2021; 16:e0245500. [PMID: 33481839 PMCID: PMC7822244 DOI: 10.1371/journal.pone.0245500] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Accepted: 12/30/2020] [Indexed: 12/26/2022] Open
Abstract
Aim To evaluate the prevalence and associated factors of abnormal renal function among Ethiopian HIV-infected patients at baseline prior to initiation of antiretroviral therapy (ART) and during follow-up. Methods We conducted a retrospective observational cohort study of HIV infected patients who initiated ART at the outpatient ART clinic of Mehal Meda Hospital of North Shewa, Ethiopia from January 2012 to August 2018. Demographic and clinical data were abstracted from the medical records of patients. Renal function was assessed by estimated glomerular filtration rate (eGFR) calculated using the Modification of Diet in Renal Disease (MDRD) equation. Univariate and multivariate analysis were conducted to determine the factors associated with abnormal renal function at baseline and during follow-up. Results Among 353 patients, 70 (19.8%) had baseline eGFR <60 ml/min/1.73m2 and 102 (28.9%) had eGFR = 60–89.9 ml/min/1.73m2. Factors associated with baseline renal impairment (eGFR <60 ml/min/1.73m2) included female sex (AOR = 3.52, CI 1.75–7.09), CD4 count < 200 cells/mm3 (AOR = 2.75, CI 1.40–5.42), BMI < 25 Kg/m2 (AOR = 3.04, CI 1.15–8.92), low hemoglobin (AOR = 2.19, CI 1.16–4.09) and high total cholesterol (AOR = 3.15, CI 1.68–5.92). After a median of 3.0 years of ART, the mean eGFR declined from 112.9 ± 81.2 ml/min/1.73m2 at baseline to 93.9 ± 60.6 ml/min/1.73m2 (P < 0.001). The prevalence of renal impairment increased from 19.8% at baseline to 22.1% during follow-up. Of 181 patients with baseline normal renal function, 49.7% experienced some degree of renal impairment. Older age (AOR = 3.85, 95% CI 2.03–7.31), female sex (AOR = 4.18, 95% CI 2.08–8.40), low baseline CD4 (AOR = 2.41, 95% CI 1.24–4.69), low current CD4 count (AOR = 2.32, 95% CI 1.15–4.68), high BMI (AOR = 2.91, 95% CI 1.49–5.71), and low hemoglobin (AOR = 3.38, 95% CI 2.00–7.46) were the factors associated with renal impairment during follow-up. Conclusion Impaired renal function was common in HIV-infected patients initiating ART in an outpatient setting in Ethiopia, and there appears to be a high prevalence of renal impairment after a median ART follow-up of 3 years. There is a need for assessment of renal function at baseline before ART initiation and regular monitoring of renal function for patients with HIV during follow-up.

Abstract
OBJECTIVES The aim of the study was to describe the prevalence of elevated body mass index (BMI) in a cohort of treatment-naïve people living with HIV (PLWH) and to investigate the association of BMI with CD4 count and noninfectious comorbidities including hypertension and renal impairment. METHODS A retrospective cohort study of 1598 PLWH at the Newlands Clinic in Harare, Zimbabwe was carried out. Data were extracted from the medical records at baseline and 6 months after initiation of treatment. The univariate association between BMI and CD4 count was assessed and multiple regression models were used to predict factors associated with loss of renal function and change in CD4 count at 6 months. RESULTS Overweight and obesity (BMI ≥ 25 kg/m2 ) were prevalent in this cohort (34%), as was the presence of hypertension (18%). Higher BMI was associated with a higher CD4 count at baseline and 6 months (B = 0.28 and 0.24, respectively; P < 0.001 for both), adjusted for age and sex. The presence of hypertension independently predicted loss of renal function at 6 months (B = -15.31; P < 0.001), adjusted for BMI, CD4 count and sex. High BMI itself was also independently associated with a decline in renal function (B = -0.41; P = 0.003), adjusted for other significant variables. CONCLUSIONS We demonstrate a high prevalence of overweight/obesity and hypertension in an urban cohort of PLWH in Zimbabwe. Higher BMI was associated with a higher CD4 count, both before and 6 months after commencing antiretroviral therapy; it was also associated with loss of renal function in this cohort.

Abstract
PURPOSE OF REVIEW With the advent of highly active antiretroviral therapy (ART), the life span of persons with HIV (PWH) has been nearly normalized. With aging, prevalence of the metabolic syndrome (MetS), including hypertension, has increased in the HIV population and exceeds that in the general population in some studies. This is due to a combination of traditional risk factors in addition to the effects attributable to the virus and ART. We review recent findings on the mechanisms contributing to MetS and hypertension in PWH, particularly those specific to the viral infection and to ART. RECENT FINDINGS Activation of the renin-angiotensin-aldosterone system (RAAS) and chronic immune activation contribute to the development of MetS and hypertension in PWH. HIV proteins and some ART agents alter adipocyte health contributing to dyslipidemias, weight gain, and insulin resistance. HIV infection also contributes to hypertension by direct effects on the RAAS that intertwine with inflammation by the RAAS also contributing to T cell activation. Recent data suggest that in addition to current ART, therapeutic targeting of the MetS and hypertension in PWH, by interfering with the RAAS, treating insulin resistance directly or by use of immunomodulators that dampen inflammation, may be critical for preventing or treating these risk factors and to improve overall cardiovascular complications in the HIV-infected aging population.

Abstract
Despite effective antiretroviral therapy (ART), people living with HIV (PLWH) still present persistent chronic immune activation and inflammation. This condition is the result of several factors including thymic dysfunction, persistent antigen stimulation due to low residual viremia, microbial translocation and dysbiosis, caused by the disruption of the gut mucosa, co-infections, and cumulative ART toxicity. All of these factors can create a vicious cycle that does not allow the full control of immune activation and inflammation, leading to an increased risk of developing non-AIDS co-morbidities such as metabolic syndrome and cardiovascular diseases. This review aims to provide an overview of the most recent data about HIV-associated inflammation and chronic immune exhaustion in PLWH under effective ART. Furthermore, we discuss new therapy approaches that are currently being tested to reduce the risk of developing inflammation, ART toxicity, and non-AIDS co-morbidities.
