Nutritional supplementation in HIV-infected individuals in South India: a prospective interventional study

Effect of Nutritional Supplementation on Illness Outcome in Adolescents with HIV on HAART: A Randomized, Double-Blind Clinical Trial

OBJECTIVE

To assess the effect of macronutrient and micronutrient supplementation on body mass index (BMI), hemoglobin (Hb), CD4 count, triglyceride levels, and morbidity among adolescents with human immunodeficiency virus (HIV) living in India.

METHODS

A prospective, randomized, double-blinded, placebo-controlled trial was conducted among 80 adolescents (10-19 y) with HIV on highly active antiretroviral therapy (HAART) for a minimum of 6 mo using simple randomization. Participants in the intervention arm received 400 kcal and 15 g protein as a powder daily and multivitamin tablets thrice weekly for 3 mo. Those in the placebo arm received a similar-appearing sachet containing 100 kcal and 2 g protein daily and a placebo tablet thrice weekly. Weight, height, BMI, Hb, CD4 count, triglycerides, and number of intercurrent illnesses were measured at 3 and 6 mo.

RESULTS

At 6 mo, the intervention group showed an increase in weight from 36.4 ± 10.9 kg to 39.7 ± 8.5 kg and a significant increase in BMI from 16.6 ± 2.3 kg/m2 to 17.5 ± 2.3 kg/m2. Increase in CD4 count in the placebo arm was more than that in the intervention arm, but the difference between the arms was not statistically significant. Intervention group showed a pronounced rise in Hb from 9.7 ± 2.3 g/dL to 11.4 ± 1.6 g/dL, significant reduction in triglyceride levels from 99.2 ± 92.7 mg/dL to 81.0 ± 12.8 mg/dL and reduction in intercurrent illnesses from 32.5% to none.

CONCLUSIONS

Nutritional supplementation of adolescents with HIV on HAART improves BMI, hemoglobin, and reduces triglyceride levels and intercurrent illnesses.

Assessing the Diets of Young Children and Adolescents in India: Challenges and Opportunities

Sustainably addressing the crisis of undernutrition for children and adolescents in underserved and resource-limited communities will require, among other investments, interventions aimed at optimizing the diets of these vulnerable populations. However, to date, there are substantial global gaps in the collection of dietary data in children and adolescents. This review article summarizes the challenges and opportunities in assessing diet among children and adolescents in India. National surveys in India identify the scale of the triple burden of malnutrition (undernutrition, micronutrient deficiencies and overnutrition) in children and adolescents and assess key nutrition and food security indicators for making informed policy decisions. However, national surveys do not collect data on diet, instead relying on anthropometry, biomarkers of micronutrient deficiencies, and summary measures of diet, such as the WHO infant and young child feeding summary indicators. Sub-national surveys and the scientific literature thus fill important gaps in describing the nutrient intakes of children and adolescents in India; however large gaps remain. Future research can be improved by investments in infrastructure to streamline the assessment of diet in India. The current challenges confronting the collection and analysis of high-quality dietary data occur in both the data collection and data analysis phases. Common methods for assessing diets in low-resource settings-such as 24 h recalls and food frequency questionnaires are particularly challenging to implement well in young children and adolescents due to motivation and memory issues in young respondents. Additionally, there are challenges with parental recall including children having multiple caretakers and meals outside the home. Furthermore, analysis of dietary data is hindered by the lack of affordable, accessible software for dietary data analysis relevant to the diversity in Indian diets. New technologies can address some of the challenges in dietary data collection and analysis, but to date, there are no platforms designed for population-level dietary assessment in India. Public and private sector investment in dietary assessment, as well as collaboration of researchers and the creation of open-source platforms for the sharing of data inputs (local food lists, recipe databases, etc.) will be essential to build infrastructure to better understand the diets of children and adolescents in India and improve dietary interventions in these target groups.

Risk and protective factors for depressive symptoms among the youth living with HIV in Namibia

BACKGROUND

: Namibia has one of the highest HIV prevalence rates among young people living with HIV and AIDS. The study of mental well-being among this vulnerable population is emerging as an important area of public health research.

METHODS

: This study examined how gender, social support, food insecurity, HIV-related stigma, HIV treatment adherence and HIV transmission knowledge are related to depressive symptoms among young people living with HIV in rural northern Namibia. Data were collected from 188 participants from the Zambezi region.

RESULTS

: The hierarchical regression analysis revealed that being a female infected with HIV, having perceived food insecurity, experiencing more HIV-related stigma and having low levels of social support can exacerbate the severity of depressive symptoms in this sample of Namibian youth.

DISCUSSION

: Our findings point to the need to expand social support interventions, enhance socio-economic programmes and reduce HIV-related stigma among young people living with HIV, especially those residing in rural, HIV endemic, resource-limited communities in developing countries.

Characteristics and impacts ofSystematic review nutritional programmes to address undernutrition of adults living with HIV in sub-Saharan Africa: a systematic review of evidence

OBJECTIVES

Although some studies have identified various challenges affecting nutritional programmes to effectively tackle undernutrition among people living with HIV, evidence about the characteristics and impacts of these programmes on weight-related nutritional outcomes varies based on country contexts, specific programme goals and the implementation processes. This systematic review sought to synthesise evidence on the characteristics and impact of nutritional programmes on weight-related nutritional outcomes of people living with HIV in sub-Saharan Africa.

DESIGN

Systematic review.

DATA SOURCES

We searched for primary studies published in the following databases: Web of Science, Medline, Scopus, ScienceDirect, ProQuest and Google Scholar, supplemented by checking reference lists of included papers.

ELIGIBILITY CRITERIA

Studies published from 2005 to 10 July 2020 and reporting on the weight-related nutritional outcomes of undernourished people enrolled in nutritional programmes in HIV care in sub-Saharan Africa were included.

DATA EXTRACTION AND SYNTHESIS

Data were extracted using a data extraction proforma. Weight-related nutritional outcomes of people living with HIV before and after enrolment in a nutritional programme were compared and narratively synthesised.

RESULTS

Sixteen studies assessing the impact of nutritional programmes in HIV care on weight-related nutritional outcomes were included. Of these, 13 examined nutritional programmes implemented in health facilities and the remaining three were delivered outside of health facilities. Nutritional recovery (defined differently in the studies) ranged from 13.1% to 67.9%. Overall programme failure rate, which included default after enrolment in a nutritional programme or non-response, ranged from 37.6% to 48.0%. More specifically, non-response to a nutritional programme ranged from 21.0% to 67.4% and default from the programme ranged from 19.0% to 70.6%. Key sociodemographic, clinical and nutritional characteristics that affect nutritional recovery, non-response and default were also identified.

CONCLUSIONS AND RECOMMENDATIONS

Nutritional programmes in HIV care have led to some improvements in weight-related nutritional outcomes among people living with HIV. However, the programmes were characterised by a high magnitude of default and non-response. To improve desired weight-related nutritional outcomes of people living with HIV, a holistic approach that addresses longer-term determinants of undernutrition is needed.

Dietary advice with or without oral nutritional supplements for disease-related malnutrition in adults

BACKGROUND

Disease-related malnutrition has been reported in 10% to 55% of people in hospital and the community and is associated with significant health and social-care costs. Dietary advice (DA) encouraging consumption of energy- and nutrient-rich foods rather than oral nutritional supplements (ONS) may be an initial treatment.

OBJECTIVES

To examine evidence that DA with/without ONS in adults with disease-related malnutrition improves survival, weight, anthropometry and quality of life (QoL).

SEARCH METHODS

We identified relevant publications from comprehensive electronic database searches and handsearching. Last search: 01 March 2021.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of DA with/without ONS in adults with disease-related malnutrition in any healthcare setting compared with no advice, ONS or DA alone.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed study eligibility, risk of bias, extracted data and graded evidence.

MAIN RESULTS

We included 94, mostly parallel, RCTs (102 comparisons; 10,284 adults) across many conditions possibly explaining the high heterogeneity.  Participants were mostly older people in hospital, residential care and the community, with limited reporting on their sex. Studies lasted from one month to 6.5 years.  DA versus no advice - 24 RCTs (3523 participants) Most outcomes had low-certainty evidence. There may be little or no effect on mortality after three months, RR 0.87 (95% confidence interval (CI) 0.26 to 2.96), or at later time points. We had no three-month data, but advice may make little or no difference to hospitalisations, or days in hospital after four to six months and up to 12 months. A similar effect was seen for complications at up to three months, MD 0.00 (95% CI -0.32 to 0.32) and between four and six months. Advice may improve weight after three months, MD 0.97 kg (95% CI 0.06 to 1.87) continuing at four to six months and up to 12 months; and may result in a greater gain in fat-free mass (FFM) after 12 months, but not earlier. It may also improve global QoL at up to three months, MD 3.30 (95% CI 1.47 to 5.13), but not later. DA versus ONS - 12 RCTs (852 participants) All outcomes had low-certainty evidence. There may be little or no effect on mortality after three months, RR 0.66 (95% CI 0.34 to 1.26), or at later time points. Either intervention may make little or no difference to hospitalisations at three months, RR 0.36 (95% CI 0.04 to 3.24), but ONS may reduce hospitalisations up to six months. There was little or no difference between groups in weight change at three months, MD -0.14 kg (95% CI -2.01 to 1.74), or between four to six months. Advice (one study) may lead to better global QoL scores but only after 12 months. No study reported days in hospital, complications or FFM. DA versus DA plus ONS - 22 RCTs (1286 participants) Most outcomes had low-certainty evidence. There may be little or no effect on mortality after three months, RR 0.92 (95% CI 0.47 to 1.80) or at later time points. At three months advice may lead to fewer hospitalisations, RR 1.70 (95% CI 1.04 to 2.77), but not at up to six months. There may be little or no effect on length of hospital stay at up to three months, MD -1.07 (95% CI -4.10 to 1.97). At three months DA plus ONS may lead to fewer complications, RR 0.75 (95% CI o.56 to 0.99); greater weight gain, MD 1.15 kg (95% CI 0.42 to 1.87); and better global QoL scores, MD 0.33 (95% CI 0.09 to 0.57), but this was not seen at other time points. There was no effect on FFM at three months. DA plus ONS if required versus no advice or ONS - 31 RCTs (3308 participants) Evidence was moderate- to low-certainty. There may be little or no effect on mortality at three months, RR 0.82 (95% CI 0.58 to 1.16) or at later time points. Similarly, little or no effect on hospitalisations at three months, RR 0.83 (95% CI 0.59 to 1.15), at four to six months and up to 12 months; on days in hospital at three months, MD -0.12 (95% CI -2.48 to 2.25) or for complications at any time point. At three months, advice plus ONS probably improve weight, MD 1.25 kg (95% CI 0.73 to 1.76) and may improve FFM, 0.82 (95% CI 0.35 to 1.29), but these effects were not seen later. There may be little or no effect of either intervention on global QoL scores at three months, but advice plus ONS may improve scores at up to 12 months. DA plus ONS versus no advice or ONS - 13 RCTs (1315 participants) Evidence was low- to very low-certainty. There may be little or no effect on mortality after three months, RR 0.91 (95% CI 0.55 to 1.52) or at later time points. No study reported hospitalisations and there may be little or no effect on days in hospital after three months, MD -1.81 (95% CI -3.65 to 0.04) or six months. Advice plus ONS may lead to fewer complications up to three months, MD 0.42 (95% CI 0.20 to 0.89) (one study). Interventions may make little or no difference to weight at three months, MD 1.08 kg (95% CI -0.17 to 2.33); however, advice plus ONS may improve weight at four to six months and up to 12 months. Interventions may make little or no difference in FFM or global QoL scores at any time point.

AUTHORS' CONCLUSIONS

We found no evidence of an effect of any intervention on mortality. There may be weight gain with DA and with DA plus ONS in the short term, but the benefits of DA when compared with ONS are uncertain. The size and direction of effect and the length of intervention and follow-up required for benefits to emerge were inconsistent for all other outcomes.  There were too few data for many outcomes to allow meaningful conclusions. Studies focusing on both patient-centred and healthcare outcomes are needed to address the questions in this review.

Mortality and Attrition Rates within the First Year of Antiretroviral Therapy Initiation among People Living with HIV in Guangxi, China: An Observational Cohort Study

Objective

To assess the mortality and attrition rates within the first year of antiretroviral therapy (ART) initiation among people living with human immunodeficiency virus (PLHIV) in rural Guangxi, China.

Design

Observational cohort study. Setting. The core treatment indicators and data were collected with standard and essential procedures as per the Free ART Manual guidelines across all the rural health care centers of Guangxi. Participants. 58,115 PLHIV who were under ART were included in the study. Interventions. The data collected included sociodemographic characteristics that consist of age, sex, marital status, route of HIV transmission, CD4 cell count before ART, initial ART regimen, level of ART site, and year of ART initiation. Primary and Secondary Outcome Measures. Mortality and attrition rate following ART initiation.

Results

The average mortality rate was 5.94 deaths, and 17.52 attritions per 100 person-years within the first year of ART initiation among PLHIV. The mortality rate was higher among intravenous drug users (Adjusted Hazard Ratio (AHR) 1.27, 95% Confidence Interval (CI) 1.14-1.43), prefecture as a level of ART site (AHR 1.14, 95% CI 1.02-1.28), and county as the level of ART site (AHR 2.12, 95% CI 1.90-2.37). Attrition was higher among intravenous drug users (AHR 1.87, 95% CI 1.75-2.00), the first-line ART containing AZT (AHR 1.09, 95% CI 1.03-1.16), and first-line ART containing LVP/r (AHR 1.34, 95% CI 1.23-1.46).

Conclusion

The mortality and attrition rates were both at the highest level in the first year of post-ART; continued improvement in the quality of HIV treatment and care is needed.

Chronic Disease Self-Management Challenges among Rural Women Living with HIV/AIDS in Prakasam, Andhra Pradesh, India: A Qualitative Study

Rural women living with HIV/AIDS (WLHA) in India experience challenges self-managing HIV/AIDS in their rural communities. The purpose of this qualitative study was to explore factors influencing their care and antiretroviral treatment (ART) adherence. Themes that emerged from the qualitative focus groups among WLHA (N = 24) in rural Prakasam, Andhra Pradesh, India, included: (1) coming to know about HIV and other health conditions, (2) experiences being on ART, (3) challenges maintaining a nutritious diet, (4) factors affecting health care access and quality, and (5) seeking support for a better future. Chronic disease self-management in rural locales is challenging, given the number of barriers which rural women experience on a daily basis. These findings suggest a need for individual- and structural-level supports that will aid in assisting rural WLHA to self-manage HIV/AIDS as a chronic illness.

Impact of counseling in knowledge, attitude and practice and association of nutritional status with CD4 count and opportunistic infections of HIV patients of Udupi, India

BACKGROUND AND AIMS

HIV infection and insufficient nutritional intake form a malicious cycle which leads to immunodeficiency and malnutrition. Thus, this research was done to see the effect of nutritional counseling on knowledge, attitude and practice (KAP) of HIV patients of Udupi district. Also, the rational evidence of association of nutritional status with CD4 counts and opportunistic infections combined are limited which led to design of this study.

METHODS

This interventional study was done in ART Centre, Udupi, India with a sample size of 66 with 33 each in experimental and control group (EG and CG). At first, the biochemical parameters, KAP, 3 day dietary intake and food group intake over Food Frequency Questionnaire (FFQ) were recorded. PG-SGA (Scored Patient-Generated Subjective Global Assessment) scoring was used to categorize patients' nutritional status. Individual nutritional counseling was provided to EG and change in KAP of EG and CG were recorded after 1 month.

RESULTS

Pre-KAP mean of EG was 151.56 which increased to 169.13 after intervention. The mean KAP score of EG was statistically different from CG after counseling, P < 0.001. Of the total, 15 (22.7%) patients were found to be malnourished. The dietary intake of nutrients and food group was significantly lower than RDA. Tukey HSD post hoc analysis showed significant statistical difference for the CD4 count between moderate and severe malnourished category with P = 0.017. Statistically significant nutrient intake differences were also observed between PGSGA groups while odds ratio showed no significant association.

CONCLUSIONS

Improvement in KAP and poor nutritional status indicates that individual Nutrition and Health Education Counseling be made an integral part in the management of HIV in Udupi. Also, the difference in CD4 count across two PG-SGA stages depicts an association between nutritional status and immune status of HIV patients.

Investigating Responses to Food Insecurity Among HIV Positive People in Resource Rich Settings: A Systematic Review

Many of the 36.7 million people living with HIV are also assumed to be food insecure. The implications of food insecurity in people living with HIV are significant, with food insecurity associated with an increased likelihood of tobacco, alcohol, and illicit drug use, experiences of depression or depressive symptoms, poor adherence and delayed uptake of HIV medication, nutritional vulnerability leading to interference of medication, and the uptake of risky behaviours as a way to gain access to food resources. This review sought to present the current intervention research around the experiences of food insecurity in PLWHA in high resource countries to determine successful models to address the issue. Only five articles were identified in a systematic search, three reported on studies that were conducted in the USA and two in Canada. Two articles were cross sectional, one was a program evaluation, one ethnography, and one took a qualitative approach. This review highlights a lack of published research in the area of HIV and food insecurity in resource rich countries. The findings of this study suggest that there are currently no standard or best practice ways to provide food aid to PLWHA to reduce food security. The lack of published results means that while there may be good programs operating in the community, this information and knowledge is not being shared, resulting in a lack of consistency in approach, possible duplication, and the potential for wasted resources. Overall, this review suggests a need for more dedicated evaluation and longitudinal research.

Undernutrition & tuberculosis in India: Situation analysis & the way forward

Undernutrition and tuberculosis (TB) are linked and have a bidirectional relationship. Undernutrition increases the risk of TB which in turn, can lead to malnutrition. Undernutrition not only is a risk factor for progression of latent TB infection to active disease, but also increases the risk of drug toxicity, relapse and death once TB develops. The dietary intake of TB patients in the country is inadequate. Nutritional supplementation in patients with TB is associated with faster sputum conversion, higher cure and treatment completion rates, significant gain in body weight and body composition as well as better performance status.

The Government of India has various social support schemes (including nutrition supplementation schemes) and policies, at the Centre as well as State levels. Here we discuss some successful examples and suggest a few solutions to address this gap; like considering TB patients as a vulnerable group for “Targeted Public Distribution System” and providing extra rations for the duration of treatment. Recommendations for the research community, civil societies, government organizations, non-governmental and corporate sector on the actions needed to achieve the goals of the End TB Strategy are also provided. Ultimately, reduction of TB burden in India and its elimination will require improving the nutritional status of the community as a whole.

Enteric Parasitic Infection Among Antiretroviral Therapy Naïve HIV-Seropositive People: Infection Begets Infection-Experience from Eastern India

CONTEXT

Parasitic opportunistic infections (POIs) frequently occur in HIV/AIDS patients and affect the quality of life.

AIMS

This study assessing the standard organisms in the stool of HIV-positive patients, their comparison with HIV-negative controls, their relation with various factors, is the first of its kind in the eastern part of India.

SETTINGS AND DESIGN

hospital-based case-control study.

MATERIALS AND METHODS

A total of 194 antiretroviral therapy naïve HIV-positive patients (18-60 years) were taken as cases and 98 age- and sex-matched HIV-negative family members as controls. Demographical, clinical, biochemical, and microbiological parameters were studied.

STATISTICAL ANALYSIS USED

Odds ratio, 95% confidence interval, and P (< 0.05 is to be significant) were calculated using Epi Info 7 software.

RESULTS

POI was significantly higher among HIV-seropositive cases (61.86%) (P < 0.001). Cryptosporidium was the most common POI in HIV-seropositive patients overall and without diarrhea; Entameba was the most common POI in patients with acute diarrhea, and Isospora was the most common POI in the patients having chronic diarrhea. Entameba was the most common POI in CD4 count <350 cells/μl while for CD4 count >350 cells/μl Cryptosporidium was the most common POI. Mean CD4 count was significantly (P < 0.001) lower among people having multiple infections. Male sex, hemoglobin <10 g/dl, WHO Clinical Stage 3 or 4, tuberculosis, absolute eosinophil count of more than 540/dl, CD4 count <350 cells/μl, and seroconcordance of spouses were significantly associated with HIV-seropositive cases having POI (P < 0.05).

CONCLUSIONS

Physicians should advise HIV-infected patients to undergo routine evaluation for POI, and provision of chemoprophylaxis should be made in appropriate settings.

The effect of standard dose multivitamin supplementation on disease progression in HIV-infected adults initiating HAART: a randomized double blind placebo-controlled trial in Uganda

BACKGROUND

Efficacy trials investigating the effect of multivitamin (MV) supplementations among patients on Highly Active Antiretroviral Therapy (HAART) have so far been inconclusive. We conducted a randomized, double blind, placebo controlled trial to determine the effect of one recommended daily allowance (RDA) of MV supplementation on disease progression in patients initiating HAART.

METHODS

Eligible subjects were randomized to receive placebo or MV supplementation including vitamins B-complex, C and E. Participants were followed for up to 18 months. Primary endpoints were: change in CD4 cell count, weight and quality of life (QoL). Secondary endpoints were: i) development of a new or recurrent HIV disease progression event, including all-cause mortality; ii) switching from first- to second-line antiretroviral therapy (ART); and iii) occurrence of an adverse event. Intent-to-treat analysis, using linear regression mixed effects models were used to compare changes over time in the primary endpoints between the study arms. Kaplan-Meier time-to-event analysis and the log-rank test was used to compare HIV disease progression events and all-cause mortality.

RESULTS

Four hundred participants were randomized, 200 onto MV and 200 onto placebo. By month 18, the average change in CD4 cell count in the MV arm was 141 cells/uL compared to 147 cells/uL in the placebo arm, a mean difference of -6 · 17 [95 % CI -29 · 3, 16 · 9]. The average change in weight in the MV arm was 3 · 9 kg compared to 3 · 3 kg in the placebo arm, a mean difference of 0 · 54 [95 % CI -0 · 40, 1 · 48]; whereas average change in QoL scores in the MV arm was 6 · 8 compared to 8 · 8 in the placebo arm, a mean difference of -2.16 [95 % CI -4 · 59,0 · 27]. No significant differences were observed in these primary endpoints, or in occurrence of adverse events between the trial arms.

CONCLUSIONS

One RDA of MV supplementation was safe but did not have an effect on indicators of disease progression among HIV infected adults initiating HAART.

Food Insecurity and Its Relation to Psychological Well-Being Among South Indian People Living with HIV

Food insecurity (FI) and its link with depression and quality of life (QOL) among people living with HIV (PLHIV) in India are not well-documented. We analyzed cohort data from 243 male and 129 female PLHIV from Bengaluru, and found 19 % of men and 26 % of women reported moderate or severe FI over a 6-month period. Women reported higher mean depression than men, and lower mean QOL. In multivariate analyses adjusting for HIV stigma and demographic covariates, both male and female PLHIV with moderate to severe FI showed lower mean QOL than those reporting mild to no FI. Male but not female food insecure participants also had higher depression scores in adjusted regression analyses. As ART has improved the physical health of PLHIV, more effort is being invested in improving their psychological well-being. Our results suggest such interventions could benefit from including nutritional support to reduce FI among PLHIV.

Impact of daily supplementation of Spirulina platensis on the immune system of naïve HIV-1 patients in Cameroon: a 12-months single blind, randomized, multicenter trial

BACKGROUND

Micronutrient deficiencies occur early in Human Immunodeficiency Virus (HIV) infections they have reverse effects on the nutritional status. The diet supplementation with a natural nutraceutical rich in proteins and micronutrient like Spirulina platensis, may be effective and efficient in delaying HIV disease progression by frequently reported improvement in immune response.

METHODS

A prospective single-blind, randomized, multicenter study conducted on 320 HIV-1 ARV-naïve participants for 12 months. Participants received either S. platensis supplementation and standard care or standard care and local balanced diet without S. platenis. Selected hematological and biochemical as well as CD4 count cells, viral load copies were assessed at three separate times.

RESULTS

Among the 169 ART-naïve participants enrolled in the study, the female was mostly represented (67.1%). The significant increase of CD4 count cells (596.32-614.92 cells count) and significant decrease of viral load levels (74.7 × 10(3)-30.87 × 10(3) copies/mL) of the patients who received a supplementation of S. platensis was found after 6 months of treatment. Haemoglobin level was also significantly higher in the same group while the fasting blood glucose concentration decreased after 12 months compared to control.

CONCLUSION

A daily supplementation with S. platensis to diet combined with a reasonable balanced diet has significantly increased the CD4 cells and reduced the viral load after 6 months. Further studies are recommended among a large specific group of people infected by the HIV in order to investigate the mechanisms involved on the effect of S. platensis on immune system.

Nutrition assessment, counseling, and support interventions to improve health-related outcomes in people living with HIV/AIDS: a systematic review of the literature

BACKGROUND

Although numerous studies have shown that severe to moderate wasting at the time of antiretroviral therapy initiation is strongly predictive of mortality, it remains unclear whether nutritional interventions at or before antiretroviral therapy initiation will improve outcomes. This review examines data on nutrition assessment, counseling, and support interventions in resource-limited settings.

METHODS

We identified articles published between 2005 and 2014 on the effectiveness of nutrition assessment, counseling, and support interventions, particularly its impact on 5 outcomes: mortality, morbidity, retention in care, quality of life, and/or prevention of ongoing HIV transmission. We rated the overall quality of individual articles and summarized the body of evidence and expected impact for each outcome.

RESULTS

Twenty-one articles met all inclusion criteria. The overall quality of evidence was weak, predominantly because of few studies being designed to directly address the question of interest. Only 2 studies were randomized trials with no food support control groups. The remainder were randomized studies of one type of food support versus another, cohort (nonrandomized) studies, or single-arm studies. Ratings of individual study quality ranged from "medium" to "weak," and the quality of the overall body of evidence ranged from "fair" to "poor." We rated the expected impact on all outcomes as "uncertain."

CONCLUSIONS

Rigorous better designed studies in resource-limited settings are urgently needed to understand the effectiveness of nutrition assessment and counseling alone, as well as studies to understand better modalities of food support (targeting, timing, composition, form, and duration) to improve both short- and long-term patient retention in care and treatment, and clinical outcomes.

The impact of a food assistance program on nutritional status, disease progression, and food security among people living with HIV in Uganda

BACKGROUND

Although the last decade has seen increased access to antiretroviral therapy across the developing world, widespread food insecurity and undernutrition continue to compromise an effective response to the AIDS epidemic. Limited evidence exists on the potential benefit of food security and nutrition interventions to people living with HIV (PLHIV).

METHODS

We capitalized on an existing intervention to PLHIV in Uganda and conducted a prospective quasi-experimental study evaluating the impact of a monthly household food basket, provided to food insecure antiretroviral therapy-naive PLHIVs for 12 months. The outcomes of interest measured at baseline and follow-up were nutritional status [body mass index; mid-upper arm circumference and hemoglobin (Hb) concentrations], disease severity (CD4 count), and 2 measures of food security: diet quality (Individual Dietary Diversity Score) and food access (Household Food Insecurity Access Scale). We used difference-in-difference propensity score matching to examine the impact of food assistance.

RESULTS

Over 12 months, food assistance significantly increased body mass index by 0.6 kg/m (P < 0.01) and mid-upper arm circumference by 6.7 mm (P < 0.05). We found no impact on CD4 count, Hb concentrations, or Individual Dietary Diversity Score. Restricting the analysis to individuals with CD4 counts of greater than 350 cells per microliter, there were significant impacts on Hb concentrations (1.0 g/dL; P < 0.05). At the household level, food assistance increased the Household Food Insecurity Access Scale, by 2.1 points (P < 0.01).

CONCLUSIONS

This study demonstrates the potential for food assistance programming to be part of the standard of care for PLHIV in areas of widespread food insecurity.

Costs of providing food assistance to HIV/AIDS patients in Sofala province, Mozambique: a retrospective analysis

BACKGROUND

As care and antiretroviral treatment (ART) for people living with HIV/AIDS become widely available, the number of people accessing these resources also increases. Despite this exceptional progress, the estimated coverage in low- and middle-income countries is still less than half of all people who need treatment. In addition, treatment discontinuation and non-adherence are still concerns for ART programs. Governments and partner institutions have sought to implement a variety of interventions addressing the main reasons behind the low coverage of, discontinuation of, and non-adherence to ART. Food assistance is one of those interventions; increasing evidence suggests that this type of intervention has the potential to improve ART outcomes. However, to our knowledge, no study has estimated its costs in detail. The objective of this study was to assess the costs of a program providing food assistance to HIV/AIDS patients in Sofala province, Mozambique, in 2009.

METHODS

We performed a retrospective analysis of the costs of providing food assistance, based on financial and economic costs. We used the ingredients approach to estimate costs, which involved multiplying the total estimated quantities of goods and services actually employed in providing the intervention by their respective unit prices.

RESULTS

In 2009, the cost of providing food assistance to HIV/AIDS patients was $2.27 million, with capital and recurrent costs accounting for 1% and 99% of total costs, respectively. Food made up the largest component, at 49% of total costs. At 24%, transport operating costs were the second largest item. The cost per patient served was $288 over 3 months.

CONCLUSION

The food distribution program carries significant costs. To assess whether it provides value for money, the present study results should be interpreted in conjunction with the program's impact, and in comparison with other programs that aim to improve adherence to ART. Our costing analysis revealed important management information, indicating that the program incurred relatively large overhead costs. This result raises questions regarding the efficiency of implementing this food distribution program.

Impact of nutritional supplementation on immune response, body mass index and bioelectrical impedance in HIV-positive patients starting antiretroviral therapy

Background

Challenges to HIV care in resource limited settings (RLS) include malnutrition. Limited evidence supports the benefit of nutritional supplementation when starting antiretroviral therapy (ART) in RLS.

Methods

Randomized controlled pilot study. HIV-positive ART-naive adults with self-reported weight loss were randomized to receive ART plus FutureLife porridge® nutritional supplement (NS) (388 kcal/day) or ART alone (Controls) for 6 months. Patients returned for monthly assessments and blood was drawn at enrolment and 6 months on ART. Differences in body composition, biochemical and laboratory parameters were estimated at 6 months on treatment.

Results

Of the 36 randomized patients, 26 completed the 6 month follow-up (11 NS vs 15 Controls). At enrolment, groups were similar in terms of age, gender, body mass index (BMI) and bioelectrical impedance. NS patients had a lower median CD4 count (60 cells/mm³ [IQR 12–105 vs 107 cells/mm³ [IQR 63–165]; p = 0.149) and hemoglobin (10.3 g/dL [IQR 9.0-11.3] vs 13.1 g/dL [IQR 11.1-14.7]; p = 0.001).

At 6 months, NS patients increased their median CD4 count by 151 cells/mm³ [IQR 120–174) vs 77 cells/mm³ [IQR 33–145] in the Controls. NS patients had higher mean percentage change in body weight (12.7% vs 4.9%; p = 0.047), BMI (7.8% vs 5.5%; p = 0.007), absolute CD4 count (83.0% vs 46.4%, p = 0.002) and hemoglobin (9.5% vs 1.0%; p = 0.026). Patients in the NS arm had a higher mean percentage fat-free mass (16.7% vs −3.5%, p = 0.036), total body water (13.0% vs −1.9%, p = 0.026), intracellular water (16.1% vs −4.1%, p = 0.010) and basal metabolic rate (5.3% vs −0.2%, p = 0.014) compared to Controls. Patients in the NS arm also showed an improvement in physical activity at 6 months post-ART initiation compared to Controls (p = 0.037).

Conclusion

Preliminary results are encouraging and suggest that NS taken concurrently with ART can promote weight gain, improve immune response and improve physical activity in HIV-positive patients that present at ART initiation with weight loss.

Impact of protein supplementation and care and support on body composition and CD4 count among HIV-infected women living in rural India: results from a randomized pilot clinical trial

Body composition in HIV-infected individuals is subject to many influences. We conducted a pilot 6-month randomized trial of 68 women living with AIDS (WLA) from rural India. High protein intervention combined with education and supportive care delivered by HIV-trained village women (activated social health activist [Asha] life [AL]) was compared to standard protein with usual care delivered by village community assistants (usual care [UC]). Measurements included CD4 counts, ART adherence, socio-demographics, disease characteristics (questionnaires); and anthropometry (bioimpedance analyzer). Repeated measures analysis of variance modeled associations. AL significantly gained in BMI, muscle mass, fat mass, ART adherence, and CD4 counts compared to UC, with higher weight and muscle mass gains among ART adherent (≥66%) participants who had healthier immunity (CD4 ≥450). BMI of WLA improved through high protein supplementation combined with education and supportive care. Future research is needed to determine which intervention aspect was most responsible.

Weight change at 1 mo of antiretroviral therapy and its association with subsequent mortality, morbidity, and CD4 T cell reconstitution in a Tanzanian HIV-infected adult cohort

BACKGROUND

The development of low-cost point-of-care technologies to improve HIV treatment is a major focus of current research in resource-limited settings.

OBJECTIVE

We assessed associations of body mass index (BMI; in kg/m(2)) at antiretroviral therapy (ART) initiation and weight change after 1 mo of treatment with mortality, morbidity, and CD4 T cell reconstitution.

DESIGN

A prospective cohort of 3389 Tanzanian adults initiating ART enrolled in a multivitamin trial was followed at monthly clinic visits (median: 19.7 mo). Proportional hazard models were used to analyze mortality and morbidity associations, whereas generalized estimating equations were used for CD4 T cell counts.

RESULTS

The median weight change at 1 mo of ART was +2.0% (IQR: -0.4% to +4.6%). The association of weight loss at 1 mo with subsequent mortality varied significantly by baseline BMI (P = 0.011). Participants with ≥2.5% weight loss had 6.43 times (95% CI: 3.78, 10.93 times) the hazard of mortality compared with that of participants with weight gains ≥2.5%, if their baseline BMI was <18.5 but only 2.73 times (95% CI: 1.49, 5.00 times) the hazard of mortality if their baseline BMI was ≥18.5 and <25.0. Weight loss at 1 mo was also associated with incident pneumonia (P = 0.002), oral thrush (P = 0.007), and pulmonary tuberculosis (P < 0.001) but not change in CD4 T cell counts (P > 0.05).

CONCLUSIONS

Weight loss as early as 1 mo after ART initiation can identify adults at high risk of adverse outcomes. Studies identifying reasons for and managing early weight loss are needed to improve HIV treatment, with particular urgency for malnourished adults initiating ART. The parent trial was registered at clinicaltrials.gov as NCT00383669.

Development of a nutrient-dense food supplement for HIV-infected women in rural Kenya using qualitative and quantitative research methods

OBJECTIVE

Formative research to facilitate the development, packaging and delivery of a culturally acceptable nutrition intervention for HIV-infected women in rural Kenya for an intervention trial.

DESIGN

Focus group discussion on three areas: (i) ingredients and form of the nutrition intervention, (ii) packaging and delivery and (iii) monitoring of adherence. Two single-blind taste tests with eleven different porridge formulations of various combinations of maize flour, soyabeans, peanuts, sorghum, mung beans, dried fish, raisins and dried whole milk. Follow-up acceptability focus group discussion was also conducted.

SETTING

Voi, Kenya, community based.

SUBJECTS

Focus group discussion and two taste tests (twenty-one women aged 16-55 years). Follow-up acceptability focus group discussion (four women enrolled in intervention trial).

RESULTS

The preferred porridge for taste consisted of maize, soyabeans and peanuts. For animal protein, dried whole milk and dried fish were used. Although the women disliked the taste of dried fish, it was acceptable if added in small undetectable quantities. Sugar over lime was favoured for taste. Women believed they could consume at least two cups of porridge per day without displacing their usual meals. The optimal delivery interval was believed to be every two weeks in individual serving packages. Women who had been consuming porridge for several weeks felt the taste was acceptable for long-term consumption.

CONCLUSIONS

This formative research resulted in the development, packaging and delivery of a nutrient-dense food supplement using local ingredients to meet the dietary needs of the population and acceptable for daily consumption by women in Kenya for evaluation in an intervention trial.

Rationale and design of a study using a standardized locally procured macronutrient supplement as adjunctive therapy to HIV treatment in Kenya

Poor nutritional status at initiation of antiretroviral therapy (ART) is predictive of mortality. Decreased dietary intake is a major determinant of weight loss in HIV. Despite a biological rationale to treat undernutrition in adults receiving ART, few studies have provided data on feasibility, safety, effectiveness, and sustainability of specific macronutrient supplements with HIV treatment in adults, especially supplements such as a food basket, a supplement approach seldom evaluated in spite of its wide use. We present the rationale and design for a study of a locally procured macronutrient supplement given to HIV-infected patients initiating ART with a body mass index (BMI) ≤20.0 kg/m(2). The objective was to determine feasibility of procurement, distribution, safety and to obtain preliminary effectiveness data for a locally procured supplement. The design was a comparative study for 200 adult participants at two Kenya government-supported clinics. The primary outcome was BMI at 24 weeks. Supplement duration was 24 weeks, total follow-up was 48 weeks, and the study included a comparison site. Novel aspects of this study include use of a standardized macronutrient supplement to protect the participant against household food sharing, and a complementary micronutrient supplement. Comprehensive data collected included dietary intake, HIV-related quality-of-life, food security, neuropsychiatric assessments, laboratory studies, and household geomapping. Assessments were made at baseline, at 24 weeks, and at 48 weeks post-ART initiation. Challenges included establishing a partnership with local millers, distribution from the HIV clinic, food safety, and tracking of participants. These findings will help inform nutrition support programming in Kenya and similar settings, and provide needed data regarding use of macronutrient supplements as an adjunctive intervention with ART.

Selection and use of US Title II food aid products in programming contexts

BACKGROUND

Food aid provided by the United States has saved lives for almost two centuries. Delivering the right products is important, but of equal concern are the ways in which products are delivered and to whom.

OBJECTIVE

The study addresses how food products are currently used, whether interventions are appropriate to achieve nutrition objectives, and whether nutrition targets could be met more cost-effectively with a different mix of products or programs.

METHODS

The team conducted consultations with a broad range of stakeholders. A survey of Title II implementing partners was conducted, focusing on procurement and logistics, and uses of FBFs and other foods. Input of implementing partners, civil society, and donor organizations was obtained through individual consultations, international and small group meetings. More than 400 individuals accessed the project's website. The project convened a panel of experts in food technology and science, food policy, law, industry, medicine, development and humanitarian work, and the maritime industry, and held regular joint meetings with USDA and USAID. The draft report was widely disseminated and posted on the website.

RESULTS AND CONCLUSIONS

There is wide variation in the quantities of fortified blended foods provided to target populations. Most of these foods are used in health/nutrition programs, but they are also used in general family rations or as an incentive or pay. Clearer programming guidance and improved decision tools are needed to match products to nutrition goals, and programs should consider delivering nutrients across a basket of commodities, not single products. The evidence base for the effectiveness and cost-effectiveness of specific foods and programs needs to be strengthened and should be supported by FFP Research is needed to provide guidance on nutrition support for HIV/AIDS. Additional investments are needed in effective behavior change communication.

Nutrition and disease progression pre-highly active antiretroviral therapy (HAART) and post-HAART: can good nutrition delay time to HAART and affect response to HAART?

Several studies have investigated a variety of nutritional supplementation interventions in adults with HIV. In this narrative review, we summarize the evidence from 31 clinical trials that explore clinical benefits of macronutrient and micronutrient supplementation in this population while attempting to answer the question of whether good nutrition can delay the time to highly active antiretroviral therapy (HAART) initiation and response. We focused on trials published in English between 1990 and 2010 that reported on CD4 count, viral load, and disease progression or survival. Among 9 macronutrient and 22 micronutrient trials, we found that evidence for improved CD4 count and HIV viral load with nutritional supplementation was limited; only 11.1% and 36.8% of macronutrient and micronutrient supplementation trials, respectively, reported improved CD4 count; and 33.3% and 12.5% of macronutrient and micronutrient trials, respectively, reported decreased viral load. Given their utility as surrogate markers of HIV disease progression, this suggests limited evidence for nutritional interventions having an impact on delaying HAART initiation or on improving HAART response. However, there are challenges in evaluating the effects of nutritional supplementation on clinical disease in that comparisons are difficult due to heterogeneity in study design, patient population, nutrient doses and combinations, baseline levels of deficiency, and study endpoints, including lack of clarity in defining and reporting HAART status. Future studies need to adopt a more rigorous standard design with adequate power and follow-up and require a consensus on composition and dose of nutrient interventions to be tested to more specifically answer the question on the impact of nutritional interventions on HIV disease progression and HAART response.

Protein energy malnutrition impairs homeostatic proliferation of memory CD8 T cells

Nutrition is a critical but poorly understood determinant of immunity. There is abundant epidemiological evidence linking protein malnutrition to impaired vaccine efficacy and increased susceptibility to infections; yet, the role of dietary protein in immune memory homeostasis remains poorly understood. In this study, we show that protein-energy malnutrition induced in mice by low-protein (LP) feeding has a detrimental impact on CD8 memory. Relative to adequate protein (AP)-fed controls, LP feeding in lymphocytic choriomeningitis virus (LCMV)-immune mice resulted in a 2-fold decrease in LCMV-specific CD8 memory T cells. Adoptive transfer of memory cells, labeled with a division tracking dye, from AP mice into naive LP or AP mice demonstrated that protein-energy malnutrition caused profound defects in homeostatic proliferation. Remarkably, this defect occurred despite the lymphopenic environment in LP hosts. Whereas Ag-specific memory cells in LP and AP hosts were phenotypically similar, memory cells in LP hosts were markedly less responsive to polyinosinic-polycytidylic acid-induced acute proliferative signals. Furthermore, upon recall, memory cells in LP hosts displayed reduced proliferation and protection from challenge with LCMV-clone 13, resulting in impaired viral clearance in the liver. The findings show a metabolic requirement of dietary protein in sustaining functional CD8 memory and suggest that interventions to optimize dietary protein intake may improve vaccine efficacy in malnourished individuals.

Quantification of lean tissue losses during cancer and HIV infection/AIDS

PURPOSE OF REVIEW

Cancer and HIV infection/AIDS are associated with an increased risk of undernutrition and cachexia. During the past decade, patients became older, frequently overweight or obese and sedentary, conditions which are likely to result in fat-free mass (FFM) loss. This review sustains the hypothesis that FFM measurement should be implemented in routine clinical practice, to optimize the management of cancer and AIDS, as well as disease-related undernutrition.

RECENT FINDINGS

Undernutrition and FFM loss are associated with worse clinical outcome and increased therapy toxicity in cancer and AIDS patients. The emergence of the concept of sarcopenic obesity in cancer patients, a condition associated with decreased survival, demonstrates the necessity to assess their body composition with easily available methods, such as dual energy X-ray absorptiometry, computerized tomography and bioelectrical impedance analysis. FFM measurement could be helpful for guiding the choice of both disease-specific and nutritional therapies and for evaluating their efficacy and putative toxicity.

SUMMARY

FFM measurement at different steps of disease course could allow improving the guidance and efficacy of both cancer and HIV/AIDS-specific and nutritional therapies. The repeated measurement of FFM could allow reducing undernutrition-related morbidity, mortality and global healthcare costs, and could improve response and tolerance towards therapy, and quality of life.
