Prevalence of malnutrition and associated factors among adult patients on antiretroviral therapy follow-up care in Jimma Medical Center, Southwest Ethiopia

Whole-protein enteral nutrition formula supplementation reduces Escherichia and improves intestinal barrier function in HIV-infected immunological nonresponders

People living with human immunodeficiency virus (PLWH) have persistent malnutrition, intestinal barrier dysfunction, and gut microbial imbalance. The interplay between gut microbiota and nutrients is involved in the immune reconstitution of PLWH. To evaluate the effects of whole-protein enteral nutrition formula supplementation on T-cell levels, intestinal barrier function, nutritional status, and gut microbiota composition in human immunodeficiency virus (HIV)-infected immunological nonresponders (INRs) who failed to normalize CD4+ T-cell counts, with a number <350 cells/µL, a pilot study was carried out in 13 HIV-infected INRs undergoing antiretroviral therapy who received a 3-month phase supplementation of 200 mL/200 kcal/45 g whole-protein enteral nutrition formula once daily. Our primary endpoint was increased CD4+ T-cell counts. Secondary outcome parameters were changes in intestinal barrier function, nutritional status, and gut microbiota composition. We showed that CD4+ T-cell counts of HIV-infected INRs increased significantly after the 3-month supplementation. Dietary supplementation for 3 months improved the intestinal barrier function and nutritional status of HIV-infected INRs. Furthermore, the enteral nutrition formula significantly decreased the relative abundance of Escherichia at the genus level and increased the alpha diversity of gut microbiota in HIV-infected INRs. The findings demonstrated that the whole-protein enteral nutrition formula aids in reducing Escherichia and improving intestinal barrier function in HIV-infected INRs. This study provides insight into the role of nutrients in the improvement of immune reconstitution in HIV-infected INRs. This study is registered in the Chinese Clinical Trial Registry (Document No. ChiCTR2000037839; http://www.chictr.org.cn/index.aspx).

Associated factors of malnutrition status among children and adolescents living with HIV in Tanzania: Individual-level analysis and marginal effect estimation

OBJECTIVES

This study aimed to identify individual-level factors that affect malnutrition outcomes among children and adolescents living with HIV/AIDS in Tanzania.

METHODS

We used data from the National AIDS Control Programme. 70,102 participants aged 5 to 19 years attending care and treatment clinics between January to December 2021 were included. Nutritional assessments were performed by anthropometric measurement. Logistic regression models were used to evaluate risk factors. We further estimated marginal prevalence and adjusted predictions by marginal effects. Supplementary analysis assessed the accuracy of the final fitted model.

RESULTS

Prevalence of malnutrition for stunting, underweight, wasting, and anthropometric failure (CIAF) were 36.0%, 28.9%, 13.0%, and 48.0%, respectively. Several individual-level factors were significant determinants of malnutrition. Boys, participants aged 15-19 years, those switched to second- or third-line antiretroviral therapy (ART), initiated ART at ages of 5-14 years, ART duration less than 3 years, and were in advanced stages of WHO HIV clinical status had increased adjusted odds ratios and marginal prevalence. The larger AUC values for all models implied importance of identified factors accounted for malnutrition.

CONCLUSIONS

On long-term ART, nutritional interventions should be context-specific guidelines to improve growth, especially at ART initiation, ART regimen, and ART duration reckoning with age and sex.

Comparing the effect of a multisectoral agricultural intervention on HIV-related health outcomes between widowed and married women

INTRODUCTION

Widowed women make up 18-40% of the 12 million women living with HIV in eastern and southern Africa. Widowhood has also been associated with greater HIV morbidity and mortality. We compared the effectiveness of a multisectoral climate adaptive agricultural livelihood intervention (called Shamba Maisha) on food insecurity, and HIV related health outcomes among widowed and married women living with HIV in western Kenya.

METHODS

We implemented Shamba Maisha (NCT02815579) using a cluster-randomized control trial design. The intervention arm received an US$175 in-kind loan to purchase a micro-irrigation pump, seeds, and fertilizer, and received eight training sessions on sustainable agriculture and financial management. Study outcomes were measured every 6 months over a 24-month follow-up period and trends in outcomes assessed using multilevel mixed-effects models.

RESULTS

The trial enrolled 232 (61.5%) married and 145 (38.5%) widowed women. Widowed women (mean age 42.8 ± 8.4 years) were older than married women (35.8 ± 9.0 years) (p < 0.01). Almost all widowed women (97.2%) self-identified as household heads compared to 10.8% of married women. Comparing widowed vs married women, reduction in food insecurity (-3.13, 95%CI -4.42, -1.84 vs. -3.08, 95%CI -4.15, -2.02), depressive symptoms (-0.21, 95%CI -0.36, -0.07 vs. -0.19, 95%CI -0.29, -0.08), internalized stigma (-0.33, 95%CI -0.55, -0.11 vs. -0.38, 95%CI -0.57, -0.19), and anticipated stigma (-0.46 95%CI -0.65, -0.28 vs. -0.35, 95%CI -0.50, -0.21) was similar for both groups. In contrast, improvements in social support (-2.22, 95%CI -3.85, -0.59 vs. -4.00, 95%CI -5.16, -2.84; p = 0.08) and reduction in enacted stigma (0.01, 95%CI -0.06, 0.08 vs. -0.14, 95%CI -0.20, -0.09; p < 0.01) were weaker for widowed than married women.

CONCLUSIONS

Our study is among the first comparing the effect of a livelihood intervention on HIV health outcomes among widowed and married women. Widowed women experienced similar benefits as married women on individual-level outcomes, but weaker benefit on outcomes dependent on their external environment like enacted stigma and social support. Future trials and programs targeting widowed women should bolster stigma reduction and social support.

Prevalence of undernutrition and associated factors among adults taking antiretroviral therapy in sub-Saharan Africa: A systematic review and meta-analysis

BACKGROUND

Undernutrition (Body Mass Index < 18.5 kg/m2) is a common problem and a major cause of hospital admission for patients living with HIV. Though sub-Saharan Africa is the most commonly affected region with HIV and malnutrition, a meta-analysis study that estimates the prevalence and correlates of undernutrition among adults living with HIV has not yet been conducted. The objective of this study was to determine the pooled prevalence of undernutrition and associated factors among adults living with HIV/AIDS in sub-Saharan Africa.

METHODS

Studies published in English were searched systematically from databases such as PubMed, Google Scholar, and gray literature, as well as manually from references in published articles. Observational studies published from 2009 to November 2021 were included. The data extraction checklist was prepared using Microsoft Excel and includes author names, study area, publication year, sample size, prevalence/odds ratio, and confidence intervals. The results were presented and summarized in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standard. Heterogeneity was investigated using the Q test, I2, τ2, τ and predictive interval. STATA version 17 was used to analyze the data. A meta-analysis using a random-effects model was used to determine the overall prevalence and adjusted odds ratio. The study has been registered in PROSPERO with a protocol number of CRD42021268603.

RESULTS

In this study, a total of 44 studies and 22,316 participants were included. The pooled prevalence of undernutrition among adult people living with HIV (PLWHIV) was 23.72% (95% CI: 20.69-26.85). The factors associated with undernutrition were participants' age (AOR = 0.5, 95% CI: 0.29-0.88), gender (AOR = 2.08, 95% CI: 0.22-20.00), World Health Organization (WHO) clinical stage (AOR = 3.25, 95% CI: 2.57-3.93), Cluster of Differentiation 4 (CD4 count) (AOR = 1.94, 95% CI: 1.53-2.28), and duration of ART (AOR = 2.32, 95% CI: 1.6-3.02).

CONCLUSION

The pooled prevalence of undernutrition among adult PLWHIV in sub-Saharan Africa remained high. WHO clinical stage, CD4 count, duration of ART treatment, age, and sex were found to be the factors associated with undernutrition. Reinforcing nutrition counseling, care, and support for adults living with HIV is recommended. Priority nutritional screening and interventions should be provided for patients with advanced WHO clinical stages, low CD4 counts, the male gender, younger age groups, and ART beginners.

HIV and obesity: updates in management strategies

PURPOSE OF REVIEW

Weight gain has emerged as an important problem in people with HIV (PWH). When dealing with obesity, PWH face additional challenges to those without HIV. Understanding the nature of the problem and the modern evidence is essential to optimize management and identify knowledge gaps.

RECENT FINDINGS

Some PWH treated with antiretroviral therapy (ART) gain unhealthy amounts of weight and develop consequences of obesity. Newer agents have been consistently associated with excessive weight gain. Key studies are underway to inform the optimal use of specific ART in PWH dealing with obesity. For weight management, behavioral interventions fostering a healthier and active lifestyle, coupled with pharmacological therapies such as glucagon-like peptide 1 receptor agonists may be effective strategies in PWH, as recently demonstrated in those without HIV, although data in this regard is pending.

SUMMARY

A growing body of research has come to light in recent years regarding weight gain and obesity in PWH. However, much of the knowledge that inform current practices is extrapolated from studies in people without HIV. Modern ART regimens may promote excessive weight gain in some, and more research is needed to optimize ART selection and the use of weight loss medications.

Development of Hypertension and Diabetes Mellitus, and Associated Factors, Among Adult HIV Patients in Ethiopia

Background

Medical improvements and increased access to treatment have turned HIV from a highly fatal disease into a treatable and controllable disease. With the improvement in lifespan, HIV patients face increasing morbidity and mortality from chronic comorbidities (hypertension and diabetes mellitus). There is, nevertheless, a paucity of information on the scale of HIV noncommunicable disease comorbidity and its associated factors. This study aimed to investigate the incidence and predictors of chronic comorbidity in HIV patients in a resource-limited setting.

Methods

A prospective cohort study was conducted from 2019 to 2021. We included 520 HIV patients at baseline. Patients without hypertension or diabetes were followed for two years to determine the incidence of developing comorbidities. Nine trained nurses used a pre-tested structured questionnaire to collect data during routine care consultations in three hospitals in southern Ethiopia. To find predictors of these chronic comorbidities, a multivariable logistic regression analysis was used.

Results

After two years, 54 out of 377 participants, or 14%, had chronic comorbidity, which is defined as having diabetes and/or hypertension. Hypertension (12%) and diabetes (4%), respectively, were observed. When compared to those who were not overweight, the risk of developing chronic comorbidity was three times higher in overweight people [AOR = 3.45, 95% CI: (1.04, 11.45), P = 0.045]. Older participants were about 6 times more likely than younger participants to have chronic comorbidity [AOR = 4.93, 95% CI: (1.56, 15.57), P = 0.007]. Those who did not engage in regular physical activity were twice as likely to develop chronic comorbidity [AOR = 2.16, 95% CI: (1.09, 4.29), P = 0.027].

Conclusion

The incidence of chronic comorbidity was high in the study population. Targeted screening for early signs of chronic comorbidity, nutritional counseling, and awareness creation in regular physical activity programs should be integrated into HIV care to prevent and control chronic comorbidity in resource-limited settings.

Clinical and behavioral factors associated with undernutrition among highly active antiretroviral therapy users in Southwest Ethiopia

Background

Globally, about 1.9 billion adults are overweight or obese, while 462 million are underweight. These are primarily found in countries with low and middle incomes, such as Ethiopia. Undernutrition is a frequent health problem among people living with HIV/AIDS; however, no large-scale research, including several health facilities, has been conducted in Ethiopia. Thus, this study aimed to assess the nutritional status and nutrition-related factors among highly active antiretroviral therapy (HAART) users in public hospitals in Southwest Ethiopia.

Methods

A cross-sectional facility study design was conducted in all public hospitals in Southwest Ethiopia from January to March 2021. A systematic sampling technique was used to select the study participants. The collected data were entered into EpiData 3.1 and then exported to SPSS version 24 for statistical analysis. Binary logistic regression analysis was done to identify the factors associated with the outcome variable. The level of significance was declared at a P-value of <0.05, with their corresponding 95% confidence level.

Results

A total of 402 HAART users have participated with a 100% response rate. The proportion of undernutrition (BMI <18.5 kg/m2) and patients with overweight or obesity (BMI ≥25 kg/m2) were 29.3% [95% CI: (24.6-33.5)] and 10% [95% CI: (6.6-12.9)], respectively. Out of undernutrition patients, severe undernutrition (BMI <16 kg/m2) accounted for 5.6%. Factors, such as food insecurity [AOR: 3.21, 95% CI: (1.76-5.91)], history of diarrhea [AOR: 2.86, 95% CI: (1.96-6.78)], CD4 cell count ≤ [AOR: 4.72, 95% CI: (2.14-12.13)], and substance user [AOR: 4.12, 95% CI: (2.31-7.30)], were the independent factors of undernutrition.

Conclusion

This study found that the prevalence of undernutrition was high compared with other settings. The government should also pay due attention to improving the treatment of HIV/AIDS by offering nutritional support services in hospitals. Moreover, policymakers and healthcare professionals consider the effects of these factors on nutrition while providing ART services.

Levels of undernutrition and associated factors among adults receiving highly active anti-retroviral therapy in health institutions in Bench Maji Zone, Southwest Ethiopia in 2018

Background

Nutritional issues are common in people with Human Immune Virus (HIV). At some point, almost everyone living with HIV faces challenges in maintaining good nutrition. There is insufficient evidence-based information on undernutrition in adults living with HIV on Highly Active Anti-Retroviral Therapy.

Objective

To assess the magnitude of undernutrition and associated factors among patients receiving Highly Active Anti-Retroviral Therapy in health facilities in the Bench Maji Zone, southwest Ethiopia in 2018.

Methods

A facility-based cross-sectional study design was employed from 1 May to 30 June 2018 on 1,007 study subjects and the participants were selected by using a consecutive sampling technique. Five health facilities were selected through a simple random sampling technique. Data were entered into Epi Data Statistical software version 3.1 and analyzed using Statistical Package for Social Sciences (SPSS) software version 21.0. Logistic regression analysis was used to identify factors associated with undernutrition in adults receiving ART. Odds ratios with 95 % confidence intervals were used to examine associations between dependent and independent variables.

Result

Of the total 1,007 study subjects, 961 participated in the study. More than half of the participants were female (61.2%), 57.2% were married and 42.9% were in the 30–39 years age group. In this study, the level of undernutrition among patients on antiretroviral therapy was 16%. Age ≥50 [AOR 2.5, 95% CI (1.1–5.6)], being single [AOR 2.2, 95% CI (1.4–3.7)], developing gastrointestinal symptoms [AOR 2.6, 95% CI (1.5–4.4)] and in WHO-defined clinical stages III and IV of HIV/AIDS [AOR 2.8, 95% CI (1.3–6.0)] were found to have a statistically significant association with undernutrition.

Conclusion

Significant numbers of people on highly active antiretroviral therapy in the study area were undernourished. This demonstrated that HIV/AIDs and its treatment directly or indirectly impacted the nutritional status of the patients, who need a critical follow-up from health workers. Age, marital status, progressing to WHO-defined clinical stage of disease, and development of gastrointestinal symptoms were identified as factors that contribute to undernutrition among patients on highly active antiretroviral therapy. The health care workers and experts working at the ART clinic should focus on patient counseling regarding the early prevention, detection, and treatment of opportunistic infections. Early health-seeking behaviors before the AIDs stage and critical follow-up are the first actions to identify undernutrition.

Mucosal-associated invariant T cells: a cryptic coordinator in HIV-infected immune reconstitution

Human immunodeficiency virus type 1 (HIV-1) infection causes considerable morbidity and mortality worldwide. Although antiretroviral therapy (ART) has largely transformed HIV infection from a fatal disease to a chronic condition, approximately 10%~40% of HIV-infected individuals who receive effective ART and sustain long-term viral suppression still cannot achieve optimal immune reconstitution. These patients are called immunological non-responders, a state associated with poor clinical prognosis. Mucosal-associated invariant T (MAIT) cells are an evolutionarily conserved unconventional T cell subset defined by expression of semi-invariant αβ T cell receptor (TCR), which recognizes metabolites derived from the riboflavin biosynthetic pathway presented on major histocompatibility complex (MHC)-related protein-1 (MR1). MAIT cells, which are considered to act as a bridge between innate and adaptive immunity, produce a wide range of cytokines and cytotoxic molecules upon activation through TCR-dependent and TCR-independent mechanisms, which is of major importance in defense against a variety of pathogens. In addition, MAIT cells are involved in autoimmune and immune-mediated diseases. The number of MAIT cells is dramatically and irreversibly decreased in the early stage of HIV infection and is not fully restored even after long-term suppressive ART. In light of the important role of MAIT cells in mucosal immunity and because microbial translocation is inversely associated with CD4⁺ T cell counts, we propose that MAIT cells participate in the maintenance of intestinal barrier integrity and microbial homeostasis, thus further affecting immune reconstitution in HIV-infected individuals.

Severe Acute Malnutrition (SAM) associated mortality rate of children attending HIV/AIDS care in North West Ethiopia, 2009–2019

Objective:

This study aimed to assess Severe Acute Malnutrition (SAM) associated mortality rate of children attending HIV/AIDS care in North West Ethiopia 2009–2019.

Methods:

Institutional-based retrospective cohort study was employed among 721 on antiretroviral therapy care seropositive children since 2009–2019. Data were entered using EpiData version 4.2 and exported to STATA (SE) R-14 version statistical software for further analysis. Beside, Besides, WHO (World Health Organization) Anthro Plus software was used to assess the nutritional status of the children. Bivariable and multivariable Cox regression analyses were conducted to identify the predictors of mortality. Finally, variables with p-value less than 0.05 were considered significant predictors of mortality.

Result:

Overall, 721 (N = 721) seropositive children were included with a mean (±SD) age of 118.4 ± 38.24 months. A median time of death was reported at 19.5 months (interquartile range = ±8.5). The overall mortality rate in this study was determined as 5.4 per 100 child-years (95% confidence interval: 3.6–5.8). Severe stunting (height for age Z-score <−3) (hazard ratio = 2.9, 95% confidence interval: 1.8–6.4), admission with septic shock (hazard ratio = 2.3, 95% confidence interval: 1.2–4.3, p < 0.008), CD4+ count below threshold (hazard ratio = 1.6, 95% confidence interval: 1.19–7.9), and World Health Organization Stages III and IV (hazard ratio = 2.9, 95% confidence interval: 1.8–6.4) were at high risk of mortality.

Conclusion:

A high rate of SAM associated mortality rate within short median (±SD) time to death was reported as compared with previous finding in Ethiopia. Seropositive children presenting with CD4 counts being below a threshold, World Health Organization Stages III and IV, and being nutritionally stunted during antiretroviral therapy initiation were at high risk of early mortality.

Effects of Undernutrition and Predictors on the Survival Status of HIV-Positive Children after Started Antiretroviral Therapy (ART) in Northwest Ethiopia

Malnutrition and human immunodeficiency virus/acquired immunodeficiency syndrome have complex and multidirectional relationships. Ethiopia is one of the countries hardest hit by the HIV epidemic as well as malnutrition. This study was aimed at assessing the effects of undernutrition on the survival status of HIV-positive children who received HIV/AIDS care in Northwest Ethiopia. Materials and Methods. A facility-based retrospective follow-up was conducted from January 1, 2009, to December 31, 2020. The data was entered into EpiData version 4.2.0. Then, the entered data was exported to STATA 14 software for further analysis, and the Kaplan-Meier survival curve was used to estimate survival time after the initiation of ART. The Bivariable and multivariable Cox regression analyses were conducted to identify predictors of mortality associated with undernutrition. Results. The mean (±SD) age of participant children was found 118.4 (±38.24) months. The overall mortality rate in this study was determined as 5.4 per 100 child-years (95% CI: 3.6, 5.8). Children with CD4 cell counts below the threshold [AHR = 1.6; 95% CI (1.19, 7.85)], advanced WHO clinical stages (III and IV) HIV [AHR = 4.5; 95% CI (2.80, 8.40)], and being severe stunting at the beginning [AHR = 2.9; 95% CI (1.80, 6.40)] were significantly associated with mortality of HIV-positive children. Conclusion. The findings of the current study indicated that HIV-positive children on ART had a high rate of mortality. Baseline undernutrition has the mortality of children who had CD4 counts below a threshold, advanced WHO HIV clinical staging (III and IV), and being severe stunting (HAZ ≤ −3 Z score) which were found to be independent predictors for mortality of undernourished HIV.

Time to develop severe acute malnutrition and its predictors among children living with HIV in the era of test and treat strategies at South Gondar hospitals, northwest, Ethiopia, 2021: a multicentre retrospective cohort study

BACKGROUND

Although severe acute malnutrition is a major public issue among HIV infected children, there is no prior evidence in Ethiopia. Hence, this study aims to assess the time to develop severe acute malnutrition and its predictors among children living with human immunodeficiency virus in Ethiopia, 2012.

METHODS

An institution based retrospective cohort study was conducted in South Gondar hospitals among 363 HIV infected children from February 10, 2014, to January 7, 2021. Epi-data version 3.1 was used to enter data, which was then exported to STATA version 14 for analysis. Besides, WHO (World Health Organization) Anthro Plus software was used to assess the nutritional status of the children. A standardized data extraction tool was used to collect the data. The Kaplan Meier survival curve was used to estimate the median survival time. The Cox-proportional hazard model assumption was checked via the Schoenfeld residual ph test and a stph plot. Bivariable and multivariable Cox proportional hazard models were employed at 95% confidence intervals (CI). A variable having a p-value < 0.05 was considered a statistically significant predictor of severe acute malnutrition.

RESULTS

A total of 363 children living with HIV, 97 (26.72%) developed severe acute malnutrition during the follow-up period. The overall incidence rate was 5.4 (95% CI: 4.7-5.9) person per year with a total of 21, 492 months or 1791 years of observation. Moreover, the median survival time was 126 months. Treatment failure [AHR =3.4 (95% CI: 2.05-5.75)], CD4 count below threshold [AHR =2.5 (95% CI: 1.64-3.95)], and WHO stage III & IV [AHR =2.9 (95% CI: 1.74-4.73)] were all significant predictors of severe acute malnutrition.

CONCLUSION

The time to develop severe acute malnutrition was found to be very low. Treatment failure, CD4 count below threshold, and WHO stage III were all significant predictors of severe acute malnutrition. Hence, emphasizing those predictor variables is essential for preventing and controlling the occurrence of severe acute malnutrition among HIV infected children.

Pre-Digested Protein Enteral Nutritional Supplementation Enhances Recovery of CD4+ T Cells and Repair of Intestinal Barrier in HIV-Infected Immunological Non-Responders

AIDS patients with immune non-response are prone to malnutrition, intestinal barrier damage, thus aggravating chronic immune activation and inflammation. However, nutritional interventions targeting malnutrition may be beneficial to restore immune function, improve clinical outcomes, and reduce mortality remains largely unclear. This work aimed to evaluate the efficacy of a nutritional supplement in HIV-infected immune non-responders (INRs). The subjects received oral supplementation of a pre-digested protein nutrition formula for three months. We show that the CD4⁺ T and CD8⁺ T cell counts were significantly increased after supplementation of the pre-digested enteral nutritional supplement. Among all pro-inflammatory cytokines in the serum, only IL-1β level was significantly decreased, while TNF-β was significantly increased (P < 0.05). The levels of intestinal mucosal damage markers, diamine oxidase (DAO), D-lactic acid (D-lactate), and lipopolysaccharide (LPS), decreased significantly (P < 0.05) after the nutritional intervention. Moreover, at month 3 after the intervention, the body weight, body mass index, albumin, and hemoglobin of all subjects were significantly increased (P < 0.05). The correlation analysis demonstrated a significantly negative correlation of CD4⁺ T cell count with levels of DAO (r = -0.343, P = 0.004), D-lactate (r = -0.250, P = 0.037), respectively, and a significantly positive correlation of IL-1β level with levels of DAO (r = 0.445, P < 0.001), D-lactate (r = 0.523, P < 0.001), and LPS (r = 0.622, P < 0.001). We conclude that the pre-digested enteral nutrition supplement is effective for HIV-infected INRs.

Phase angle as predictor of malnutrition in people living with HIV/AIDS

BACKGROUND

Phase angle (PhA), measured by bioelectrical impedance analysis (BIA) has been studied as an indicator of survival in people living with HIV (PLWH). However, it remains unclear whether PhA is associated with malnutrition or low CD4+ T-cell counts.

OBJECTIVE

In this study, we assessed the discriminative capacity of PhA for malnutrition detection using Global Leadership Initiative on Malnutrition (GLIM) criteria in PLWH, aiming to propose cutoff points for this population.

METHODS

This retrospective observational study included 427 adult PLWH (13% female). Participants were classified according to malnutrition status by using GLIM criteria. Body composition was assessed by using BIA. CD4+ T-cell counts were determined by flow cytometry.

RESULTS

According to GLIM criteria, 30% of the participants were malnourished. Multivariate regression analysis showed that PhA (adjusted odds ratio [OR], 0.10; 95% CI, 0.05-0.18; P < 0.001), fat-mass percentage (adjusted OR, 0.86; 95% CI, 0.82-0.90; P < 0.001), and male sex (adjusted OR, 0.26; 95% CI, 0.09-0.76; P = 0.013) were independently associated with malnutrition. A PhA cutoff of 5.45° in men and 4.95° in women may predict malnutrition with sensitivity and specificity >70%.

CONCLUSION

PhA could be a valid, useful, and simple predictor of malnutrition in PLWH.

Overweight and Obesity Among Adult HIV Infected Peoples Receiving ART in Ethiopia: A Systematic Review and Meta-Analysis

BACKGROUND

Over-nutrition and diet-linked non-communicable morbidities are showing increasing trend overtime. Even if there are different factors that affect the change in BMI other than ART, several authors have reported increases in BMI among PLHIV on treatment that are equal to or surpass the general population. This study is aimed to estimate the prevalence of obesity and overweight among adult HIV infected peoples taking ART in Ethiopia.

METHOD

PubMed, CINAHL, Web of science, global health and Google scholar electronic databases were used to perform a systematic literature search. Two authors independently extracted all the necessary data using a structured data extraction format. Data analysis was done using STATA Version 14. The heterogeneity of the studies was assessed by using I2 test. A random-effects model was used to estimate the pooled prevalence. Publication bias was checked using Funnel plot and Egger's test.

RESULT

Two thousand seven hundred and fifty-one studies were reviewed and 13 studies fulfilling the inclusion criteria were included in the meta-analysis. The meta-analysis of 13 studies, comprising 4994 participants resulted in pooled prevalence of overweight to be 17.85% (95% CI: 12.22-23.47). Whereas, the pooled prevalence of overweight was found to be 3.90 (95% CI: 2.31-5.49) but after adjusting for publication bias using trim and fill analysis it has become 3.58 (95% CI: 2.04-5.13). Magnitude of both overweight and obesity was higher in studies conducted in Addis Ababa, studies done after 2016 and studies having sample size of less than 400, in subgroup analysis.

CONCLUSION

The magnitude of overweight and obesity among HIV infected peoples taking ART in Ethiopia is high. There is a need to have a routine screening to PLWHA on the risk of over-nutrition in order to facilitate early detection.

Regulation of Gut Microbiota on Immune Reconstitution in Patients With Acquired Immunodeficiency Syndrome

Human immunodeficiency virus type 1 (HIV-1) infection of CD4⁺ T cells in the gut plays an insidious role in acquired immunodeficiency syndrome (AIDS) pathogenesis. Host immune function is closely related to gut microbiota. Changes in the gut microbiota cause a different immune response. Previous studies revealed that HIV-1 infection caused changes in gut microbiota, which induced immune deficiency. HIV-1 infection results in an abnormal composition and function of the gut microbiota, which may disrupt the intestinal epithelial barrier and microbial translocation, leading to long-term immune activation, including inflammation and metabolic disorders. At the same time, an abnormal gut microbiota also hinders the effect of antiviral therapy and affects the immune reconstruction of patients. However, studies on the impact of the gut microbiota on immune reconstitution in patients with HIV/AIDS are still limited. In this review, we focus on changes in the gut microbiota caused by HIV infection, as well as the impact and regulation of the gut microbiota on immune function and immune reconstitution, while we also discuss the potential impact of probiotics/prebiotics and fecal microbiota transplantation (FMT) on immune reconstitution.

Undernutrition and associated factors among adult HIV/AIDS patients receiving antiretroviral therapy in eastern zone of Tigray, Northern Ethiopia: a cross-sectional study

Background

Undernutrition and HIV/AIDS are highly prevalent in sub-Saharan Africa, Ethiopia inclusive as linked in a vicious cycle. Thus, several studies have documented that undernutrition among HIV/AIDS patients increases the risk of mortality, decrease survival rates, affect the overall clinical outcome and quality of life.Despite this fact, information about the burden of undernutrition and associated factors among adults receiving antiretroviral therapy is lacking in the particular study area. Hence, this study aimed to examine the prevalence of undernutrition and associated factors among adult HIV/AIADS patients receiving antiretroviral therapy patients in Eastern Zone of Tigray, Northern Ethiopia.

Methods

A cross-sectional research design was adopted in data collection while systematic sampling technique was employed to sample and select the study subjects. A structured questionnaire was used to collect information from 394 study subjects through face to face method.Also, data on demographics, laboratory and anthropometric variables were collected from each selected patients sampled.The data collected were entered and analyzed using SPSS version 22.. Bivariate and multivariable logistic regression analysis with 95% confidence interval were used to find factors associated with undernutrition. The adjusted odds ratio was calculated to show the strength of the association. Variables with p-value of < 0.05 were considered statically significant.

Results

The mean age of the respondents was 41 (± 10). Out of 394 study respondents, about 42.9% of them were undernourished (95% CI: 37.8-47.7).Respondents who had CD4+ count less than 200 cells/μl (AOR = 1.84; 95% CI: 1-3.36), being advanced clinical staging (AOR = 3.6; 95% CI: 2.11-6.18), and not taking co-trimoxazole preventive therapy (AOR = 2.38; 95% CI: 1.21-4.6) were independently associated with undernutrition.

Conclusion

The result of this study indicated that the prevalence of undernutrition was high.Respondents with advanced clinical stage of CD4+ count less than 200 cells/ul and those that were not taking co-trimoxazole preventive therapy was found to be positively associated with undernutrition.Therefore, the implementation of nutritional programs is very crucial to improve the nutritional status of HIV/AIDS patients in the particular study.

The Nutritional Status of Adult Antiretroviral Therapy Recipients with a Recent HIV Diagnosis; A Cross-Sectional Study in Primary Health Facilities in Gauteng, South Africa

The study determined the nutritional status of adult antiretroviral therapy (ART) recipients, and investigated the association between the duration on ART and the nutritional status. This study was based in primary health facilities in Gauteng, South Africa. The data collected included sociodemographic variables; the duration of the treatment; and the body mass index (BMI), classified as undernutrition (<18.5 kg/m²), normal (18.5–24.9 kg/m²), or overweight/obesity (≥25 kg/m²). ART recipients (n = 480) had a mean age of 35 (± 8.4SD) years. All had taken ART for six months or more (range 6–48 months). The data were analyzed using STATA 13.0. The overall prevalence of overweight/obesity was 39%, it was higher in females (46%) than in males (30%), 26% were overweight, and 13% were obese. Underweight was 13%, and was higher in males (18%) than females (9%). Being overweight was more likely in those aged ≥35 years and those in smaller households. Being obese was less likely in males, in the employed, and in those with a higher income, but was more likely in those with a longer duration on ART. Abdominal obesity was high, but less likely in males. Interventions to prevent overweight/obesity should be integrated into routine HIV care, while at the same time addressing the burden of undernutrition among ART recipients.

Reducing Undernutrition through Counseling on Diversified Food Intake among Adult People Living with HIV on HAART, Northern Ethiopia

BACKGROUND

HIV/AIDS and malnutrition are interrelated and exacerbate one another in a vicious cycle. As HIV infection progresses it causes catabolic state and increases susceptibility to other infections, leading to progressive aggravation of undernutrition. However, data are lacking in Ethiopia on determinants of undernutrition among people living with HIV on antiretroviral therapy. Therefore, this study aimed to assess determinants of undernutrition among adult HIV/AIDS patients in Northern Ethiopia.

METHOD

Facility-based unmatched case-control study was conducted among 324 randomly selected people living with HIV on antiretroviral therapy (ART). A structured and pretested interviewer questionnaire was used to collect data, while digital Seca weight and Seca measuring rod were used to measure weight and height, respectively. Logistic regression was used to identify independent factors of undernutrition, and p value <0.05 was declared for statistical significance. All statistical analyses were performed using SPSS 21™.

RESULT

This study revealed that people of younger age and those on ART (AOR = 0.29 (95% CI: 0.10, 0.84)) had low risk of being undernourished. However, average individual monthly income (AOR = 2.61 (95% CI: 1.48, 4.61)), not receiving nutritional counseling during visits (AOR = 2.5 (95% CI: 1.52-3.89)), and low diet diversity (AOR = 10.55 (95% CI: 4.17, 26.73)) had higher odds of undernutrition among people living with HIV/AIDS.

CONCLUSION

Age of patients, average monthly income, nutritional counseling during visits, and diet diversity were the independent factors of undernutrition. Counseling on well-timed and sufficient consumption of nutritious foods, economic strengthening, and livelihood activities is important. Future longitudinal study is necessary to elucidate the problem of undernutrition among people living with HIV/AIDS.
