Abstract
INTRODUCTION Antiretroviral Therapy (ART) gives people living with HIV/AIDS (PLWHA) a new perspective of life, although some develop changes in impaired body composition. This study aimed to assess the factors associated with changes in body composition in PLWHA using ART, depending food consumption. MATERIAL AND METHODS It was a cross-sectional study and took place through interviews with patients treated at an University Hospital. Secondary data: CD4+ T cells, ART time and age. The level of physical activity and smoking were self-reported. For the assessment of body composition, electrical bioimpedance and measurements of weight, height and waist circumference were used. RESULTS The highest percentages of fat mass and fat-free mass, in treatment for more than 5 years, were in the female group (p <0.01), aged> 50 years (p = 0.02) and in the male group (p <0.01), young adult (p <0.01), respectively. The final linear regression model for both free fat mass and fat mass had sex, age, smoking and nutritional diagnosis as relevant factors. The frequency of food consumption was inadequate for calories, carbohydrates, proteins and lipids was high, however it did not significantly influence body composition. CONCLUSIONS Gender, age, smoking and nutritional diagnosis by BMI significantly influence body composition.

Abstract
OBJECTIVE To conduct a comprehensive systematic review and meta-analysis of the available literature on the anthropometric nutritional status of South African infants and children, 0-18 years old and to report on trends of changes in nutritional status over the period 1997-2022. DESIGN Systematic review and meta-analysis. SETTING Review of the available literature on the anthropometric nutritional status of South African infants and children, 0-18 years old, over the period 1997-2022. PARTICIPANTS South African infants and children, 0-18 years old. RESULTS Only quantitative data from ninety-five publications that described the nutritional status in terms of anthropometry were included. Most recent studies applied the WHO 2006 and 2007 definitions for malnutrition among children 0-5 years old and 5-19 years old, respectively. Meta-analysis of all prevalence data shows the highest stunting prevalence of 25·1 % among infants and preschool children, compared to 11·3 % among primary school-age children and 9·6 % among adolescents. Furthermore, the overweight and obesity prevalence was similar among children younger than 6 years and adolescents (19 %), compared to 12·5 % among primary school-age children. In national surveys, adolescent overweight prevalence increased from 16·9 % in 2002 to 23·1 % in 2011. Meta-regression analysis shows a decrease in stunting among children 6-18 years old and an increase in combined overweight and obesity in the 10-19 years age group. CONCLUSION The double burden of malnutrition remains evident in South Africa with stunting and overweight/obesity the most prevalent forms of malnutrition among children.

Abstract
INTRODUCTION HIV is associated with accelerated cardiovascular disease, due to HIV-associated metabolic abnormalities, antiretroviral therapy (ART), and HIV itself. Carotid-femoral pulse wave velocity (PWV) is the noninvasive gold standard measurement of arterial stiffness, and associated with incident vascular events in adults. It is unclear if arterial stiffness is accelerated in children living with perinatal HIV (CHIV) who initiate ART early in life. We compared the longitudinal trajectory of PWV in CHIV to children unexposed to HIV. A secondary comparison compared HIV exposed uninfected children (CHEU) to unexposed children. METHODS Four hundred and sixty-five children (141 CHIV, 160 CHEU, 164 unexposed) previously in the children with HIV early antiretroviral therapy (ART) (CHER) and P1060 trials were followed annually at Tygerberg Children's Hospital, South Africa between 2014 and 2020. CHIV initiated ART in infancy or early childhood, with excellent ART adherence and largely sustained viral suppression. The primary outcome was PWV, measured using the Vicorder system, and evaluated using linear mixed effects models. RESULTS Median (interquartile range) age at first PWV measurement was 8.64 (7.7-9.1) years, and median follow-up time 2.9 (1.6-4.0) years. Adjusted analyses showed no significant mean difference in PWV in CHIV and CHEU compared to unexposed [CHIV: 0.101 m/s, 95% confidence interval (CI) -0.012 to 0.214; CHEU: 0.068 m/s, 95% CI -0.047 to 0.183], after adjusting for gender, age, ethnicity, mean arterial pressure, resting average heart rate and family history of cardiovascular disease. CONCLUSIONS Early-treated CHIV with sustained viral suppression have similar PWV to unexposed children. Excellent adherence and early ART initiation may protect against cardiovascular disease.

Role of Selenium in Viral Infections with a Major Focus on SARS-CoV-2. Int J Mol Sci 2021; 23:ijms23010280. [PMID: 35008706 PMCID: PMC8745607 DOI: 10.3390/ijms23010280] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 12/22/2021] [Accepted: 12/24/2021] [Indexed: 02/06/2023] Open
Abstract
Viral infections have afflicted human health and despite great advancements in scientific knowledge and technologies, continue to affect our society today. The current coronavirus (COVID-19) pandemic has put a spotlight on the need to review the evidence on the impact of nutritional strategies to maintain a healthy immune system, particularly in instances where there are limited therapeutic treatments. Selenium, an essential trace element in humans, has a long history of lowering the occurrence and severity of viral infections. Much of the benefits derived from selenium are due to its incorporation into selenocysteine, an important component of proteins known as selenoproteins. Viral infections are associated with an increase in reactive oxygen species and may result in oxidative stress. Studies suggest that selenium deficiency alters immune response and viral infection by increasing oxidative stress and the rate of mutations in the viral genome, leading to an increase in pathogenicity and damage to the host. This review examines viral infections, including the novel SARS-CoV-2, in the context of selenium, in order to inform potential nutritional strategies to maintain a healthy immune system.

Influence of Healthy Habits Counseling on Biochemical and Metabolic Parameters in Children and Adolescents with HIV: Longitudinal Study. Nutrients 2021; 13:nu13093237. [PMID: 34579114 PMCID: PMC8466268 DOI: 10.3390/nu13093237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Revised: 08/03/2021] [Accepted: 08/06/2021] [Indexed: 11/17/2022] Open
Abstract
We analyze the influence of dietary counseling and physical activity on biochemical and metabolic parameters in children and adolescents with HIV. A longitudinal experimental study, including three analyses: At the beginning, 4th month, and 8th month. A sample of 18 subjects with HIV of both sexes, mean age 10.4 ± 4.50 years. Usual food intake (24 h recall and food intake marker), level of habitual physical activity, biochemical parameters, resting metabolic rate, as well as body composition (dual-energy X-ray absorptiometry), biological maturation, and anamnesis with clinical data and socioeconomic were evaluated. There was an effect of time on the reduction of blood glucose and triglycerides and the resting metabolic rate. There was a significant increase in fruit consumption throughout the study. The consumption of soft drinks decreased when comparing analysis periods 1 and 2, however, it increased again in analysis period 3. There was no significant effect of time on the set of variables related to a food recall. Counseling healthy habits and regular clinical follow-up were relevant for improving biochemical parameters (glucose, triglyceride, HDL cholesterol), maintaining the resting metabolic rate, increasing fruit consumption, and decreasing the consumption of soft drinks, in part of the time, of children and adolescents with HIV. Finally, we emphasize that counseling positively influenced healthy habits, and these, in turn, improved health-related parameters.

Abstract
The etiology of multifactorial morbidities such as undernutrition and anemia in children living with the human immunodeficiency virus (HIV) (HIV+) on antiretroviral therapy (ART) is poorly understood. Our objective was to examine associations of HIV and iron status with nutritional and inflammatory status, anemia, and dietary intake in school-aged South African children. Using a two-way factorial case-control design, we compared four groups of 8 to 13-year-old South African schoolchildren: (1) HIV+ and low iron stores (inflammation-unadjusted serum ferritin ≤ 40 µg/L), n = 43; (2) HIV+ and iron sufficient non-anemic (inflammation-unadjusted serum ferritin > 40 µg/L, hemoglobin ≥ 115 g/L), n = 41; (3) children without HIV (HIV-ve) and low iron stores, n = 45; and (4) HIV-ve and iron sufficient non-anemic, n = 45. We assessed height, weight, plasma ferritin (PF), soluble transferrin receptor (sTfR), plasma retinol-binding protein, plasma zinc, C-reactive protein (CRP), α-1-acid glycoprotein (AGP), hemoglobin, mean corpuscular volume, and selected nutrient intakes. Both HIV and low iron stores were associated with lower height-for-age Z-scores (HAZ, p < 0.001 and p = 0.02, respectively), while both HIV and sufficient iron stores were associated with significantly higher CRP and AGP concentrations. HIV+ children with low iron stores had significantly lower HAZ, significantly higher sTfR concentrations, and significantly higher prevalence of subclinical inflammation (CRP 0.05 to 4.99 mg/L) (54%) than both HIV-ve groups. HIV was associated with 2.5-fold higher odds of iron deficient erythropoiesis (sTfR > 8.3 mg/L) (95% CI: 1.03–5.8, p = 0.04), 2.7-fold higher odds of subclinical inflammation (95% CI: 1.4–5.3, p = 0.004), and 12-fold higher odds of macrocytosis (95% CI: 6–27, p < 0.001). Compared to HIV-ve counterparts, HIV+ children reported significantly lower daily intake of animal protein, muscle protein, heme iron, calcium, riboflavin, and vitamin B12, and significantly higher proportions of HIV+ children did not meet vitamin A and fiber requirements. Compared to iron sufficient non-anemic counterparts, children with low iron stores reported significantly higher daily intake of plant protein, lower daily intake of vitamin A, and lower proportions of inadequate fiber intake. Along with best treatment practices for HIV, optimizing dietary intake in HIV+ children could improve nutritional status and anemia in this vulnerable population. This study was registered at clinicaltrials.gov as NCT03572010.

Nutritional status and dietary diversity of school-age children living with HIV: a cross-sectional study in Phnom Penh, Cambodia. BMC Public Health 2020; 20:1181. [PMID: 32727433 PMCID: PMC7388459 DOI: 10.1186/s12889-020-09238-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Accepted: 07/12/2020] [Indexed: 12/24/2022] Open
Abstract
Background HIV/AIDS continues to be a major public health concern for children. Each day, worldwide, approximately 440 children became newly infected with HIV, and 270 children died from AIDS-related causes in 2018. Poor nutrition has been associated with accelerated disease progression, and sufficient dietary diversity is considered a key to improve children’s nutritional status. Therefore, this study aims to 1) examine nutritional status of school-age children living with HIV in Phnom Penh, Cambodia, and 2) identify factors associated with their nutritional status, especially taking their dietary diversity into consideration. Methods This cross-sectional study was conducted in May 2018 within the catchment area of the National Pediatric Hospital, Cambodia. Data from 298 children and their caregivers were included in the analyses. Using semi-structured questionnaires, face-to-face interviews were conducted to collect data regarding sociodemographic characteristics, quality of life, and dietary diversity. To assess children’s nutritional status, body weight and height were measured. Viral load and duration of antiretroviral therapy (ART) were collected from clinical records. Multiple logistic regression analyses were performed to identify factors associated with stunting and wasting. Results Of 298 children, nearly half (46.6%) were stunted, and 13.1% were wasted. The mean number of food groups consumed by the children in the past 24 h was 4.6 out of 7 groups. Factors associated with children’s stunting were age (adjusted odds ratio [AOR] 2.166, 95% confidence interval [CI]: 1.151, 4.077), household wealth (AOR 0.543, 95%CI: 0.299, 0.986), duration of receiving ART (AOR 0.510, 95%CI: 0.267, 0.974), and having disease symptoms during the past 1 year (AOR 1.871, 95%CI: 1.005, 3.480). The only factor associated with wasting was being male (AOR 5.304, 95%CI: 2.210, 12.728). Conclusions Prevalence of stunting was more than double that of non-infected school-age children living in urban areas in Cambodia. This highlights the importance of conducting nutritional intervention programs, especially tailored for children living with HIV in the country. Although dietary diversity was not significantly associated with children’s nutritional status in this study, the findings will contribute to implementing future nutritional interventions more efficiently by indicating children who are most in need of such interventions in Cambodia.
