The impact of malnutrition on survival and the CD4 count response in HIV-infected patients starting antiretroviral therapy

Prevalence and determinants of under-nutrition among children on ART in Ethiopia: A systematic review and meta-analysis

BACKGROUND

Children living with HIV/AIDS are particularly vulnerable to under-nutrition. Under-nutrition associated with HIV/AIDS infection increases the rate of morbidity and mortality in children. To reaffirm a future objective, there needs to be evidence regarding the current national burden of under-nutrition and related factors among children infected with HIV. Hence, the objective of this systematic review and meta-analysis was to estimate the pooled prevalence of under-nutrition, and the pooled effect sizes of associated factors among HIV-infected children in Ethiopia.

METHODS

We searched Ethiopian universities' online libraries, Google, Google Scholar, PubMed, CINAHL, Cochrane Library, and Scopus to find the primary studies for this review. Publication bias was checked through Egger's regression test. Heterogeneity among the included studies was assessed using the I2 test. The data were extracted using Microsoft Excel and exported to STATA Version 14 statistical software. A random effect meta-analysis model was performed to estimate the pooled prevalence of Under-nutrition.

RESULTS

After reviewing 1449 primary studies, 16 articles met the inclusion criteria and were included in the final meta-analysis. The estimated pooled prevalence of stunting, underweight, and wasting among children living with HIV/AIDS was 32.98% (95% CI: 22.47, 43.50), 29.76% (95% CI: 21.87, 37.66), and 21.16% (95% CI: 14.96, 27.35) respectively.

CONCLUSIONS

This study showed that under-nutrition among HIV-infected children in Ethiopia was significantly high. Under-nutrition is more common among HIV-infected children with opportunistic infections, child feeding problems, do not adhere to dietary recommendations, and have diarrhea. The national policies and strategies for ART service- provider centers should maximize their emphasis on reducing under-nutrition among HIV-infected children. Based on this finding, we recommend HIV intervention programs to address nutritional assessment and interventions for HIV-infected children.

The Positive Impact of Foods Support on Loss to Follow Up Among Children and Adolescents on HIV Antiretroviral Therapy in a District Hospital in East Cameroon

Introduction

The pediatric HIV treatment coverage in Cameroon remains low at 35%. The high loss to follow up (LTFU) remains a major factor to this dismal performance which is related to the lack of implementation of effective interventions to improve retention in care. This study assessed the impact of foods support (FS) on LTFU among children and adolescents in a rural district hospital in eastern Cameroon.

Methods

This was a retro-prospective study conducted in Abong Mbang District Hospital (ADH) in the East Region of Cameroon. We provided foods kits to children and adolescents initiated on antiretroviral therapy (ART) in this facility during the study and followed them up prospectively (prospective phase). On the other hand, using medical records, we collected retrospectively data for children and adolescents who enrolled on ART in the hospital prior to the study (retrospective phase). We then compared the proportions of children and adolescents LTFU before (no FS) and after (with FS) the study, using the Fisher's exact test, logistic regression, Kaplan-Meier survival curves and Cox proportional-hazards model at 5% significant level.

Results

We found that with FS, the proportion of children and adolescents LTFU was 11 times lower (2.4% vs 26.7%, p=0.014), the mean time of retention in care was 30% higher (17 months vs 12 months, p<0.001) and children and adolescents who did not receive FS were 10 times more likely to be LTFU [aHR=10.3 (4.0-26.2), p<0.001)].

Conclusion

Foods support is an effective intervention in reducing LTFU among children and adolescents on ART. This intervention should be adequately funded to enable a large-scale implementation in the field. This could help to improve the outcome of pediatric ART coverage in resource-limited settings.

High baseline body mass index predicts recovery of CD4+ T lymphocytes for HIV/AIDS patients receiving long-term antiviral therapy

The relationship between baseline BMI and CD4+ T cells during follow-up in HIV patients in China requires further evaluation. We conducted a retrospective cohort study based on adult AIDS patients who underwent or received antiretroviral therapy from 2003 to 2019 in Guangxi, China. BMI was divided into categories and compared, and after adjusting for BMI being related to the change in CD4 lymphocyte count, with normal weight as the reference group, the BMI before treatment was positively correlated with the changes in CD4+ T cells at different time periods. Among them, obese patients had significant CD4+ cell gain. In patients with pretreatment CD4+ T lymphocyte counts <200 cells/μL, a higher BMI was associated with an increased likelihood of achieving immunologic reconstitution [≥350 cells/μL: AHR: 1.02(1.01, 1.04), P = 0.004; ≥500 cells/μL: AHR: 1.03 (1.01, 1.05), P = 0.004]. Underweight in HIV patients was a risk factor for poor viral suppression [AHR: 1.24 (1.04, 1.48), P = 0.016]. Our study demonstrated that HIV/AIDS patients receiving ART with higher baseline BMI had better immune reconstitution and that baseline BMI could be an important predictor of immune reconstitution in patients receiving ART. Baseline BMI was not associated with virological failure, but a lower baseline BMI indicated poor viral suppression during follow-up.

Temporal and Spatial Distribution of Opportunistic Infections Associated with the Human Immunodeficiency Virus (HIV) in Uganda

The human immunodeficiency virus (HIV) remains one of the greatest challenges of the twenty-first century in the absence of an effective vaccine or cure. It is estimated globally that close to 38 million people are currently living with the HIV virus and more than 36 million have succumbed to this deadly virus from the time the first case was reported in early 1980s. The virus degrades the human body immunity and makes it more vulnerable to different kinds of opportunistic infections (OIs). However, with the introduction of highly active anti-retroviral therapy (HAART) in 2003, the pattern and frequency of OIs has been progressively changing though with variations in the different parts of the World. So this chapter discusses the temporal and spatial patterns of OIs in Uganda.

Nutritional aberration and related morphological disorders among patients with human immunodeficiency virus infection on combination antiretroviral therapy (cART) in Ghana: A retrospective study

Background

Metabolic and nutritional abnormalities among people living with human immunodeficiency virus (PLHIV) have been reported due to either their HIV infection, primary malnutrition caused by insufficient intake or consequences of the ART regimen provided. This study investigated the prevalence and patterns of nutritional abnormalities including morphological changes among HIV patients under combination Antiretroviral Therapy (cART) in the Bia-West District of the Western North Region.

Methods

We employed a hospital-based retrospective longitudinal design. Records of 180 patients with HIV infection before and after antiretroviral therapy (ART) initiation were extracted at the Essam Government Hospital. Eligibility criteria included being on treatment without change in regimen for at least one year and without defaulting in scheduled visits. Data extracted included patients' demography, nutritional parameters and medication history. We assessed patients’ nutritional characteristics with the subjective global assessment (SGA) tool which includes five components of medical history (weight change, dietary intake, gastrointestinal symptoms, functional capacity & metabolic stress) and two components of physical examination (signs of fat loss and muscle wasting, alterations in fluid balance).

Results

Malnutrition, lipodystrophy and body wasting among HIV patients were 48.3% (36.5–62.4), 43.9% (32.6–57.7) and 33.3% (23.6–46.0) respectively. Incremental percentage trends of malnutrition (stage I- 7.4%, stage II -22.4%, stage III-24.7%) and lipodystrophy (Stage I - 22.2%, Stage II - 48.7%, Stage III - 51.9%) were significantly associated with worsening disease status. Patients on AZT+3TC + NVP combined regimen presented with the highest malnutrition [52.9% (28.5–76.1)], lipodystrophy [64.7% (38.6–84.7)] and loss of muscle mass [47.1% (23.9–71.5)]. Long-term ART use was significantly associated with high malnutrition rate (p= 0.02620) and increasing muscle mass loss (p = 0.0040).

Conclusion

High malnutrition, lipodystrophy and muscle wasting exist in PLHIV on cART in the Bia-West District. These adverse nutritional effects may be modulated by disease severity, ARV medication and duration.

Body mass index, proteinuria and total lymphocyte counts in predicting treatment responses among ART naïve individuals with HIV initiated on antiretroviral treatment in Dar es Salaam, Tanzania, 2019: a cohort study

OBJECTIVES

To explore the potential use of body mass index (BMI), proteinuria and total lymphocyte count changes in predicting immunological and virological response in individuals with HIV initiated on antiretroviral treatment (ART).

DESIGN

Prospective cohort study.

SETTING

Three urban HIV care and treatment centres in Dar es Salaam.

PARTICIPANTS

Individuals with HIV initiating ART.

OUTCOME MEASURES

HIV viral load ≥1000 copies/mL (viral non-suppression) at 6 months after ART initiation.

RESULTS

Of 215 (out of 220 enrolled) participants who returned for evaluation at 6 months, 147 (66.8%) were women. At 6 months of follow-up, 89.4% (76/85) of participants with sustained weight gain were virally suppressed compared with 31.8% (7/22) with sustained loss, p<0.001. In participants who were lymphopaenic at baseline, an increase to normal total lymphocyte counts at 6 months was associated with an increase in CD4 count compared with participants who remained lymphopaenic, 96.2% (50/52) versus 54.8% (17/31), p<0.001. At baseline, 50.0% (110/220) had proteinuria. In participants without proteinuria from baseline to 6 months, 89.8% (79/88) were virally suppressed compared with participants with proteinuria at baseline and/or 3 months, 85.6% (77/90), those with persistent proteinuria, 30.8% (8/26), and proteinuria at 6 months only, 45.5% (5/11), p<0.001. In modified Poisson regression, the independent predictors other than CD4 cell counts for viral non-suppression at 6 months among individuals with HIV initiating on ART were BMI loss >5% from baseline to 6 months (adjusted RR 2.73, 95% CI (1.36 to 5.47)), lymphopaenia at 6 months (adjusted RR=4.54, 95% CI (2.19 to 9.39)) and proteinuria at 6 months (adjusted RR=2.63, 95% CI (1.25 to 5.54)).

CONCLUSIONS

Change in BMI, total lymphocyte count and presence of proteinuria can monitor and predict ART response and may be particularly helpful in settings when CD4 counts and viral load monitoring are unavailable.

Effects of different integrase strand transfer inhibitors on body weight in patients with HIV/AIDS: a network meta-analysis

Background

Global antiretroviral therapy has entered a new era. Integrase strand transfer inhibitor (INSTI) has become the first choice in acquired immunodeficiency syndrome (AIDS) treatment. Because INSTI has high antiviral efficacy, rapid virus inhibition, and good tolerance. However, INSTIs may increase the risk of obesity. Each INSTI has its unique impact on weight gain in patients with human immunodeficiency virus (HIV)/AIDS. This study systematically assessed different INSTIs in causing significant weight gain in HIV/AIDS patients by integrating data from relevant literature.

Methods

PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), China Science and Technology Journal Database (VIP), and Wanfang databases were searched to find studies on the influence of different INSTIs in weight gain. Data on weight change were extracted, and a network meta-analysis was performed.

Results

Eight studies reported weight changes in HIV/AIDS patients were included. Results of the network meta-analysis showed that the weight gain of HIV/AIDS patients treated with Dolutegravir (DTG) was significantly higher than that of Elvitegravir (EVG) [MD = 1.13, (0.18–2.07)]. The consistency test results showed no overall and local inconsistency, and no significant difference in the results of the direct and indirect comparison was detected (p > 0.05). The rank order of probability was DTG (79.2%) > Bictegravir (BIC) (77.9%) > Raltegravir (RAL) (33.2%) > EVG (9.7%), suggesting that DTG may be the INSTI drug that causes the most significant weight gain in HIV/AIDS patients.

Conclusion

According to the data analysis, among the existing INSTIs, DTG may be the drug that causes the most significant weight gain in HIV/AIDS patients, followed by BIC.

HIV, Tuberculosis, and Food Insecurity in Africa—A Syndemics-Based Scoping Review

The double burden of HIV/AIDS and tuberculosis (TB), coupled with endemic and problematic food insecurity in Africa, can interact to negatively impact health outcomes, creating a syndemic. For people living with HIV/AIDS (PWH), food insecurity is a significant risk factor for acquiring TB due to the strong nutritional influences and co-occurring contextual barriers. We aim to synthesize evidence on the syndemic relationship between HIV/AIDS and TB co-infection and food insecurity in Africa. We conducted a scoping review of studies in Africa that included co-infected adults and children, with evidence of food insecurity, characterized by insufficient to lack of access to macronutrients. We sourced information from major public health databases. Qualitative, narrative analysis was used to synthesize the data. Of 1072 articles screened, 18 articles discussed the syndemic effect of HIV/AIDS and TB co-infection and food insecurity. Reporting of food insecurity was inconsistent, however, five studies estimated it using a validated scale. Food insecure co-infected adults had an average BMI of 16.5–18.5 kg/m². Negative outcomes include death (n = 6 studies), depression (n = 1 study), treatment non-adherence, weight loss, wasting, opportunistic infections, TB-related lung diseases, lethargy. Food insecurity was a precursor to co-infection, especially with the onset/increased incidence of TB in PWH. Economic, social, and facility-level factors influenced the negative impact of food insecurity on the health of co-infected individuals. Nutritional support, economic relief, and psychosocial support minimized the harmful effects of food insecurity in HIV–TB populations. Interventions that tackle one or more components of a syndemic interaction can have beneficial effects on health outcomes and experiences of PWH with TB in Africa.

HIV-associated wasting prevalence in the era of modern antiretroviral therapy

OBJECTIVE

To understand the prevalence of HIV-associated wasting (HIVAW) in the United States.

DESIGN

Medical and pharmacy claims study using IBM MarketScan Commercial, Medicare Supplemental and Medicaid Databases.

METHODS

Study period: July 2012-September 2018 (first HIV diagnosis claim = HIV index date). People with HIV (PWH) were excluded if they were aged less than 18 years, had any malignancy claim or had less than 6 months of enrollment data pre or post-HIV index date. HIVAW was defined by proxy using claims for weight loss-related diagnoses, appetite stimulant/nontestosterone anabolic agents or enteral/parenteral nutrition. Prevalence was reported cumulatively, by insurance type and antiretroviral therapy (ART) pharmacy claims (defined as ≥1 pharmacy claim of any ART within 12 months post-HIV index date). Statistical analysis assessed factors potentially associated with HIVAW.

RESULTS

The study population comprised 42 587 PWH (64.6% male, mean age 44 years, 67.5% on Medicaid, 63.9% on ART). Cumulative HIVAW prevalence (2012-2018) was 18.3% (n = 7804) for all PWH (17.9% on ART, 19.1% not on ART). HIVAW prevalence by payer was 7.5% for Commercial and Medicare Supplemental and 23.5% for Medicaid. The strongest associations with the likelihood of meeting the definition of HIVAW were for individuals with Medicaid and hospitalization(s) post-HIV index date; race and ART status were not associated.

CONCLUSIONS

Findings suggest HIVAW remains prevalent in PWH. ART use was not found to be associated with HIVAW. HIVAW was highest among those with Medicaid coverage or any hospitalization(s). Further research is needed to better understand additional factors associated with and contributing to HIVAW.

Metabolomics as a Tool to Investigate HIV/TB Co-Infection

The HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome) and tuberculosis (TB) pandemics are perpetuated by a significant global burden of HIV/TB co-infection. The synergy between HIV and Mycobacterium tuberculosis (Mtb) during co-infection of a host is well established. While this synergy is known to be driven by immunological deterioration, the metabolic mechanisms thereof remain poorly understood. Metabolomics has been applied to study various aspects of HIV and Mtb infection separately, yielding insights into infection- and treatment-induced metabolic adaptations experienced by the host. Despite the contributions that metabolomics has made to the field, this approach has not yet been systematically applied to characterize the HIV/TB co-infected state. Considering that limited HIV/TB co-infection metabolomics studies have been published to date, this review briefly summarizes what is known regarding the HIV/TB co-infection synergism from a conventional and metabolomics perspective. It then explores metabolomics as a tool for the improved characterization of HIV/TB co-infection in the context of previously published human-related HIV infection and TB investigations, respectively as well as for addressing the gaps in existing knowledge based on the similarities and deviating trends reported in these HIV infection and TB studies.

Adult malnutrition, nutritional interventions and outcomes in Singapore: a scoping review of local studies for the past 20 years

Background:

There is currently no review published on the prevalence and incidence of malnutrition in Singapore across various populations, or what interventions or policies are in place for preventing/treating malnutrition.

Objectives:

This review aims to determine the: (a) incidence and prevalence of malnutrition in the community, and in acute, intermediate and long-term care facilities; (b) interventions implemented for screening, assessing and treating/preventing malnutrition; (c) specific clinical populations investigated for malnutrition or nutritional therapy; and (d) implications of malnutrition and effectiveness of treating malnutrition or using nutritional therapy in Singapore.

Methods:

A structured search strategy was applied to available electronic databases (MEDLINE/PubMed, EMBASE, CINAHL, the Cochrane Library and Google Scholar) using selected search terms, with additional reports and grey literature identified using iterative searches.

Results:

Forty-two articles were found, with the majority of research performed in the community and acute care settings. Malnutrition screening and assessment is the most common nutritional research performed in Singapore. Approximately 14.7% to 65.0% of acute care and 2.8% to 31.5% of community populations are found to be malnourished. Limited interventional and economic-related studies are available.

Conclusion:

Malnutrition rates in Singapore appear to be similar to other developed countries. Future studies will need to focus on nutritional intervention, cost-effectiveness analyses and specific populations such as the underprivileged, chronically ill and those dependent on nutritional support.

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.

Undernutrition and HIV Infection in Sub-Saharan Africa: Health Outcomes and Therapeutic Interventions

PURPOSE OF REVIEW

Sub-Saharan Africa (SSA) is disproportionately burdened by the twin epidemics of food insecurity and HIV infection, and protein-calorie undernutrition is common among persons with HIV (PWH) initiating antiretroviral therapy (ART) in the region. In this review, we discuss the intersection of HIV infection and undernutrition, health outcomes among undernourished PWH starting ART, and the demonstrated and potential benefits of therapeutic interventions such as micro/macronutrient supplementation and pharmacological agents.

RECENT FINDINGS

A low body mass index (BMI), used as a general indicator of poor nutrition in most studies, is associated with impaired immune recovery and increased mortality in the early ART period. The increased risk of mortality is multifactorial, and contributors include undernutrition-related immune system dysfunction, increased susceptibility to opportunistic infections, and metabolic and cardiovascular dysregulation. Clinical trials of micro/macronutrient supplementary feeding, appetite stimulants (hormones and anabolic agents), and recombinant adipokines have shown a benefit for weight gain and metabolic health, but there are few data on mortality or immune recovery. A substantial proportion of PWH in SSA are undernourished, and undernutrition contributes to an increased risk of mortality and other adverse health outcomes. To date, there have been few prospective trials of nutritional supplementation and/or pharmacologic therapy among undernourished PWH in SSA, though findings from other settings suggest a potential benefit in this population.

Role of demographic and clinical factors in survival of HIV patients on antiretroviral therapy

Our retrospective cohort study assesses the survival probability and identifies the demographic and clinical predictors of mortality in HIV patients taking antiretroviral therapy using an antiretroviral therapy centre data in Western India. Secondary data on 7532 registered HIV-infected individuals between September 2006 and January 2013 were analysed. The probability of survival at 75 months was 84.9%. Significant indicators of poor chances of survival were greater age, lower occupation class, lower CD4 count, poor functional status; higher stage of disease, lower weight, the presence and type of opportunistic infections, co-trimoxazole therapy and poor adherence to antiretroviral therapy. We thus find that, in addition to pre-ART, antiretroviral therapy clinical status and treatment adherence, socioeconomic status plays an important influence on ultimate survival of HIV patients on antiretroviral therapy.

Greater Weight Gain in Treatment-naive Persons Starting Dolutegravir-based Antiretroviral Therapy

BACKGROUND

Recent studies have reported weight gain in virologically suppressed persons living with human immunodeficiency virus (PLWH) switched from older antiretroviral therapy (ART) to newer integrase strand transfer inhibitor (INSTI)-based regimens. In this study, we investigated whether weight gain differs among treatment-naive PLWH starting INSTI-based regimens compared to other ART regimens.

METHODS

Adult, treatment-naive PLWH in the Vanderbilt Comprehensive Care Clinic cohort initiating INSTI-, protease inhibitor (PI)-, and nonnucleoside reverse transcriptase inhibitor (NNRTI)-based ART between January 2007 and June 2016 were included. We used multivariable linear mixed-effects models to generate marginal predictions of weights over time, adjusting for baseline clinical and demographic characteristics. We used restricted cubic splines to relax linearity assumptions and bootstrapping to generate 95% confidence intervals.

RESULTS

Among 1152 ART-naive PLWH, 351 initiated INSTI-based regimens (135 dolutegravir, 153 elvitegravir, and 63 raltegravir), 86% were male, and 49% were white. At ART initiation, median age was 35 years, body mass index was 25.1 kg/m2, and CD4+ T-cell count was 318 cells/μL. Virologic suppression at 18 months was similar between different ART classes. At all examined study time points, weight gain was highest among PLWH starting dolutegravir. At 18 months, PLWH on dolutegravir gained 6.0 kg, compared to 2.6 kg for NNRTIs (P < .05), and 0.5 kg for elvitegravir (P < .05). PLWH starting dolutegravir also gained more weight at 18 months compared to raltegravir (3.4 kg) and PIs (4.1 kg), though these differences were not statistically significant.

CONCLUSIONS

Treatment-naive PLWH starting dolutegravir-based regimens gained significantly more weight at 18 months than those starting NNRTI-based and elvitegravir-based regimens.

Mortality and its association with CD4 cell count and hemoglobin level among children on antiretroviral therapy in Ethiopia: a systematic review and meta-analysis

Background

Even though there are advancements in HIV/AIDS prevention and treatment approach, HIV continues to be a global challenge. Pediatrics HIV is one of the challenges in the reduction of child mortality particularly in less developed countries like Ethiopia. Therefore, this study aims to estimate the pooled proportion of child mortality and the effect of hemoglobin level and CD4 cell count among children on antiretroviral therapy in Ethiopia.

Method

All published were articles searched using PubMed, EMBASE, Google Scholar, and Web of Science database. Besides, Ethiopian institutional research repositories and reference lists of included studies were used. We limited the searching to studies conducted in Ethiopia and written in the English language. Studies that were done in a cohort, cross-sectional, and case-control study design were considered for the review. The weighted inverse variance random effects model was applied, and the overall variations between studies were checked by using heterogeneity test Higgins’s (I²). Subgroup analysis by region and year of publication was conducted. All of the included articles were assessed using the Joanna Briggs Institute (JBI) quality appraisal criteria. In addition, publication bias was also checked with Egger’s regression test and the funnel plot. Based on the results, trim and fill analysis was performed to manage the publication bias.

Result

A total of 16 studies with 7047 participants were included in this systematic review and meta-analysis. The overall pooled proportion of mortality among children on antiretroviral therapy (ART) was found to be 11.78% (95% CI 9.34, 14.23). In subgroup analysis, the highest child mortality was observed in the Amhara region 16.76 % (95% CI 9.63, 23.90) and the lowest is in the Tigray region 4.81% (95% CI 2.75, 6.87). Besides, the proportion of mortality among children with low CD4 count and hemoglobin level was 2.42 (AOR = 2.42, 95% CI 1.65, 3.56) and 3.24 (AOR = 3.24, 95% CI 1.51, 6.93) times higher compared to their counterparts, respectively.

Conclusion

The proportion of mortality among children on ART was high in Ethiopia. Those children who had low CD4 cell count and low hemoglobin levels at baseline need special attention, treatment, and care.

Trial registration

The protocol of this systematic review and meta-analysis has been registered in PROSPERO with the registration number CRD42018113077.

Nutritional status and the associated factors among people living with HIV: an evidence from cross-sectional survey in hospital based antiretroviral therapy site in Kathmandu, Nepal

BACKGROUND

Nutritional status is the key concern among the people living with HIV but this issue has been failed to be prioritized in HIV strategic plan of Nepal. This study aims to assess the nutritional status among people living with HIV and determine their associated factors.

METHODS

A hospital based cross-sectional study was conducted where 350 people living with HIV attending the ART clinic were selected using systematic random sampling technique. Nutritional status among people living with HIV was assessed through anthropometry, body mass index; Underweight (body mass index < 18.5 kg/m2) and overweight/obesity (body mass index > 23 kg/m2). HIV related clinical factors such CD4 count, WHO stage, opportunistic infection, antiretroviral therapy regimen etc. were collected from the medical records. Socio-demographic data were collected using pretested structured questionnaire through interview technique. Multiple linear regression method was employed to determine the association between different independent factors and body mass index score.

RESULTS

The prevalence of underweight was found to be 18.3% (95% CI: 14.3-22.6). Most of the study participants were overweight/obese (39.1%). After subjection to multiple linear regression analysis, it was found that age, being male, being married, being in business occupation, smoking, hemoglobin level and antiretroviral therapy duration were significantly associated with body mass index score. Majority of the participants in our study lacked diversified food (62.3%).

CONCLUSION

Overweight/obesity is an emerging problem among people living with HIV. This group of participants should be screened for the presence of non-communicable disease. This study also highlights the importance of nutritional program being an integral part of HIV/AIDS continuum of care. Therefore, an effort should be made to address the burden of malnutrition by addressing the identified determinants.

Is the experience of hunger associated with risk of engaging in condomless anal sex among minority young men who have sex with men?

Although emerging evidence suggests that hunger may be a risk factor for engaging in risk behaviors that lead to HIV acquisition, this has rarely been explored for young minority men who have sex with men (YMSM). This study explored a range of sexual risk behaviors for associations with a measure of hunger, assessed among 448 YMSM residing in Los Angeles, CA. Forty-five percent experienced hunger (past 12 months). Hunger was significantly associated with engaging in any condomless anal receptive sex (CARS) (adjusted odds ratio 1.74; 95% confidence interval 1.01–3.01; P .049). Further, hunger was also significantly associated with a greater percentage of CARS (Beta .12; t 2.18; P .03). Parallel effects were not observed relative to condomless anal insertive sex. Findings suggest that the experience of hunger among young minority MSM is generally not associated with a milieu of sexual risk. One important exception is that hunger may lead to having CARS. This suggests a potential ‘trade off’ for receptive partners experiencing hunger and partially supports the idea that at hunger may predispose minority YMSM to partner demands not to use condoms.

Time to Development of Anemia and Predictors among HIV-Infected Patients Initiating ART at Felege Hiwot Referral Hospital, Northwest Ethiopia: A Retrospective Follow-Up Study

Methods

A retrospective follow-up study was conducted among clients on ART from 2012 to 2017. Data were collected using checklists. The Kaplan-Meier curve was employed to compare survival rates. The Cox proportional hazard model was applied to identify predictors of time to development of anemia.

Results

A total of 490 ART patients were followed. The overall incidence of anemia was 27/100 person-years. The incidence was highest in the second year (18.7/100 PY) of starting ART when compared with the first year (13.8/100 PY) and third year (18.1/100 PY) of ART initiation. The independent predictors show an association for time to development of anemia and were as follows: being female (AHR = 2.94, 95%CI = 2.15–4.0), pulmonary tuberculosis positive (AHR = 2.98, 95%CI = 1.62–5.51), baseline weight < 60 kg (AHR = 1.51, 95%CI = 1.19-1.92), and severe acute malnutrition (AHR = 2.0, 95%CI = 1.39-2.89).

Conclusion

Most of the anemia cases occurred after the first year of ART initiation. Pulmonary tuberculosis, baseline weight, nutritional status, and sex were predictors for anemia. Clients with low baseline weight and abnormal nutritional status need to get close follow-up to prevent the risk of early development of anemia.

Malnutrition as predictor of survival from anti-retroviral treatment among children living with HIV/AIDS in Southwest Ethiopia: survival analysis

Background

Approximately 70% of HIV positive people live in Africa where food insecurity and under nutrition are endemic. However the impact of malnutrition on treatment outcome is not clear. This study assessed the effect of under nutrition on Anti-Retroviral Therapy treatment outcome among pediatric age group living with HIV/AIDS in Public Hospitals, Southwest Ethiopia.

Method

A retrospective cohort study was conducted on records of 242 pediatric children in Guraghe zone Public Hospitals. Also median, mean, standard deviation and interquartile range were calculated. Life table, hazard function and survival function were plotted. Log rank test with 95% confidence interval of mean survival time was done. The nutritional status data were managed via WHO Anthros plus and BMI for age Z score was calculated. To assess effects of nutritional status on mortality, both Bivariate and multivariate cox proportional hazard regression was conducted with crude (CHR) and adjusted hazard ratio (AHR) (95% confidence interval and p value). P value of less than 0.05 was used as cut off point to declare statistical significance.

Results

A total of 243 records of pediatric ART records with mean age of 11.6 (± 3.8 years) were reviewed. About 178 (73.3%) have got therapeutic feeding on the course of ART treatment. Whereas significant number of children, 163 (67.1%) reported to had eating problems. A total of 13 (5.3%) children were dead with incidence density of 11.2 deaths per 1000 person years. There is significantly higher survival time among well nourished (11.1 years with 95% CI: 10.8 to 11.4) as compared to underweight children (9.76 with 95% CI: 9.19 to 10.32 years). Underweight children had almost three fold increase incidence of death (AHR = 3.01; 95% CI: 0.80–11.4). Similarly children with anemia had higher incidence of death than children without anemia (AHR = 1.55; 95% CI: 0.49–4.84).

Conclusions

Low nutritional status at the start of ART evidenced by underweight and anemia were found to be predictors of survival among HIV positive children. There should be improved, sustained and focused nutritional screening, care and treatment for children on ART follow up.

Clinico-Epidemiological Profile of Children Orphaned due to AIDS Residing in Care Giving Institutions in Coastal South India

Background

HIV/AIDS has a greater impact on children. Besides being orphaned by the untimely demise of one or both parents due to the disease, these children are more prone for discrimination by the society.

Methods

In this cross-sectional study 86 children orphaned by AIDS residing in care giving institutions for HIV positive children in Mangalore were assessed for their clinico-epidemiological profile and nutritional status. Institutional Ethics Committee clearance was obtained before the commencement of the study. The collected data were analyzed using SPSS (Statistical Package for Social Sciences) version 11.5 and the results expressed in mean (standard deviation) and proportions. BMI was calculated and nutritional status assessed using WHO Z scores (BMI for Age) for children between 5 and 19 years separately for boys and girls.

Results

The mean age of the children was 13.2 ± 3 years. Majority (n = 56, 65.1%) of the children were double orphans. Most of the children orphaned by AIDS (n = 78, 90.7%) had a history of both the parents being HIV positive. The median CD4 count of participants at the time of our study was 853.5 (IQR 552–1092) cells/microliter. A higher percentage of orphans were malnourished compared to nonorphans. (41.1% vs. 36.7%). All the educational institutions, wherein the children orphaned by AIDS were enrolled, were aware about their HIV status. Five of the participants felt discriminated in their schools. Only two of the participants felt discriminated by their friends because of their HIV status.

Conclusion

From our study we draw conclusion that even though the children orphaned due to AIDS are rehabilitated in terms of having shelter and provision of education and health care, much needs to be done in terms of improving the nutritional status of these children and alleviating the discriminatory attitude of the society towards them.

We think that advances realized in 2018 can now be utilized to ameliorate patient care.

Undernutrition and associated factors among HIV-positive adult patients enrolled in antiretroviral therapy (ART) clinics in the Arba Minch area, southern Ethiopia

Background: Undernutrition constitutes an important threat to the success of HIV programs in sub-Saharan Africa, and failure to effectively address it may jeopardize the benefits gained so far in the fight against HIV. The aim of the study was to assess undernutrition and associated factors among HIV-positive adult patients enrolled in antiretroviral therapy (ART) clinics in Arba Minch area, south Ethiopia. Methods: A facility-based cross-sectional study was conducted in 2017. There were 351 adult individual study participants who were enrolled in ART clinics in Arba Minch area public health facilities. Variables with P-value less than 0.25 on binary logistic regression analysis were entered into a multivariate logistic regression model to outline the independent predictors of undernutrition. CI of 95% was used to assess precision of the study. Results: Out of all the participants, 18.23% (95% CI: 14.52-22.65) were undernourished. The prevalence of undernutrition was significantly lower among those consuming food from five or more food groups per day (AOR: 0.33; 95% CI: 0.16-0.71) and undergoing ART for more than a year (AOR: 0.24; 95% CI: 0.08-0.73). On the contrary, the prevalence was significantly higher among those who were currently smoking tobacco (AOR: 6.67; 95% CI: 1.45-30.76). In addition, those with WHO clinical stage 3 had a significantly higher prevalence of undernutrition compared to those with WHO clinical stage 1 (AOR: 311; 95% CI: 1.47-6.60). Conclusion: The prevalence of undernutrition was high among adults with HIV/AIDS enrolled in ART clinics in the study area. The prevalence of undernutrition was lower among those who consumed diverse food groups and had been receiving ART for longer (more than a year). On the contrary, the prevalence of undernutrition was higher among those who consumed tobacco and with higher WHO clinical stage. Therefore, efforts should be made to enhance the dietary diversity of these individuals.

An optimal BMI range associated with a lower risk of mortality among HIV-infected adults initiating antiretroviral therapy in Guangxi, China

Previous studies investigating HIV-infected patients suggested a direct link between underweight and the mortality rate of AIDS. However, there was a lack of evidence showing the optimal range of initial body mass index (BMI) patients maintain during antiretroviral therapy (ART). We aimed to evaluate associations of the BMI values pre-ART and during the entire ART duration with mortality among HIV-positive individuals. In total, 5101 HIV/AIDS patients, including 1439 (28.2%) underweight, 3047 (59.7%) normal-weight, 548 (10.7%) overweight and 67 (1.3%) obese patients, were included in this cohort. The cumulative mortality of underweight, normal-weight, and overweight were 2.4/100 person-years (95% CI 1.9–2.9), 1.1/100 person-years (95% CI 0.9–1.3), and 0.5/100 person-years (95% CI 0.1–0.9), respectively. Cumulative mortality was lower in both the normal-weight and overweight populations than in the underweight population, with an adjusted hazard ratio (AHR) of 0.5 (95% CI 0.4–0.7, p < 0.001) and 0.3 (95% CI 0.1–0.6, p = 0.002), respectively. Additionally, in the 1176 patients with available viral load data, there was significant difference between the underweight and normal-weight groups after adjustment for all factors, including viral load (p = 0.031). This result suggests that HIV-infected patients in Guangxi maintaining a BMI of 19–28 kg/m², especially 24–28 kg/m², have a reduced risk of death.

Determinants of undernutrition among adult patients receiving antiretroviral therapy at Debre Markos referral hospital, Northwest Ethiopia: a case-control study design

Background

A complex and negatively reinforcing relationship exists between infection with Human Immune Deficiency Virus (HIV) and malnutrition. HIV-induced immune impairment and its resulting opportunistic infections (OIs) can lead to malnutrition and nutritional deficits, can, in turn, hasten the progression of HIV infection and reduce chances of survival. The determinants of undernutrition among patients receiving antiretroviral therapy (ART) is poorly understood in Ethiopia, despite a high prevalence of food-insecurity that overlaps with a generalized HIV/AIDS epidemic. Therefore, this study aimed to assess determinants of undernutrition among adult patients receiving antiretroviral therapy at Debre Markos Referral Hospital in Northwest Ethiopia.

Methods

We conducted an institution-based, unmatched, case-control study with 636 adult patients receiving antiretroviral therapy. We randomly selected 212 patients with poor nutritional outcomes (cases) and 424 without undernutrition (controls) and then conducted a chart review to collect information on their treatment, socio-economic, and demographic background. Data were analyzed using bivariable and multivariable logistic regression to identify factors associated with under nutrition.

Results

We found that greater age (AOR = 1.02, 95% CI: 1.01,1.05), fair or poor adherence (AOR = 2.77, 95% CI: 1.40, 5.50 and AOR = 4.72, 95% CI: 1.92, 11.6), and the presence of OIs (AOR = 1.70, 95% CI: 1.12, 2.52), anemia (AOR = 1.81, 95% CI: 1.07, 3.07), or eating problems (AOR = 3.40, 95% CI: 2.27, 5.10), were all independently and positively associated with under nutrition. Starting treatment with a medium or low CD4 count was protective (AOR = 0.61, 95% CI: 0.39, 0.96 and AOR = 0.49, 95% CI: 0.27, 0.88). Having social support (AOR = 0.64, 95% CI: 0.43, 0.95), and having a source of informal care-giving (AOR = 0.48, 95% CI: 0.27, 0.84), reduced the odds of undernutrition.

Conclusion

Our findings support calls for treating HIV infection early and aggressively, while closely monitoring patients for opportunistic infections that might affect eating and drug side effects that may affect appetite. The role of disclosure, peer-caregivers and age in preventing undernutrition should be explored in future research.

Food Insecurity, Nutritional Status, and Factors Associated with Malnutrition among People Living with HIV/AIDS Attending Antiretroviral Therapy at Public Health Facilities in West Shewa Zone, Central Ethiopia

BACKGROUND

In resource limited settings, HIV/AIDS patients lack access to sufficient nutritious foods, which poses challenges to the success of antiretroviral therapy. HIV/AIDS and malnutrition are still major public health problems in Ethiopia. Though measuring nutritional status is an essential part of ART program, little evidence exists on food insecurity and nutritional status of HIV/AIDS patients in Ethiopia. Hence, the study aimed to determine food insecurity and nutritional status and contextual determinants of malnutrition among HIV/AIDS patients in West Shewa Zone, Ethiopia.

METHODS

Institution-based cross-sectional study was conducted among HIV/ADIS patients who have been attending antiretroviral therapy at public health facilities in West Shewa Zone from April to May 2016, Ethiopia. The sample size was 512 and study participants were selected from each facilities using systematic random sampling method. Data were collected using pretested questionnaire by trained data collectors. Data were entered to Epi-Info 3.5.1 for Windows and analyzed using SPSS version 22. Logistic regression analyses were conducted to determine independent factors associated with malnutrition.

RESULTS

Prevalence of malnutrition was 23.6% (95% CI: 19.7%-27.4%) and prevalence of household food insecurity was 35.2% (95% CI: 31.1%-39.0%). Factors significantly associated with malnutrition among HIV/AIDS patients were unemployment (AOR = 3.4; 95% CI: 1.8-5.3), WHO clinical stages III/IV (AOR = 3.3; 95% CI: 1.8-6.5), CD4 count less than 350 cells/μl (AOR = 2.0; 95% CI: 1.8-4.2), tuberculosis (AOR = 2.3; 95% CI: 1.3-4.9), duration on antiretroviral therapy (AOR = 1.8; 95% CI: 1.2-2.9), and household food insecurity (AOR = 5.3; 95% CI: 2.5-8.3).

CONCLUSIONS

The findings revealed high prevalence of malnutrition and household food insecurity among HIV/AIDS patients attended ART. The negative interactive effects of undernutrition, inadequate food consumption, and HIV infection demand effective cross-sectorial integrated programs and effective management of opportunistic infections like tuberculosis.

A retrospective cohort study of body mass index and survival in HIV infected patients with and without TB co-infection

Background

High early morbidity and mortality following antiretroviral therapy (ART) initiation has been a distinguishing feature of ART programmes in resource limited settings (RLS) compared to high-income countries. This study assessed how well body mass index (BMI: kg/m²) correlated with survival among HIV infected patients with and without TB co-infection.

Methods

We retrospectively evaluated clinical data from 1000 HIV infected patients, among whom 389 were also co-infected with TB, between January 2008 and December 2010, in KwaZulu-Natal, South Africa.

Results

Among 948 patients eligible for analysis, 15.7% (149/948) were underweight (< 18.50), 55.9% (530/948) had normal BMI (≥18.50–24.90), 18.7% (177/948) were overweight (25.00–29.00) and 9.7% (92/948) were obese (≥30.00). Irrespective of TB status, underweight patients, had significantly higher risk of death compared to those with normal BMI at baseline (aHR = 2.9; 95% CI: 1.5–5.7; P = 0.002).

Conclusions

Irrespective of TB co-infection, low BMI correlated with mortality in HIV infected patients.

Malnutrition and lipid abnormalities in antiretroviral naïve HIV-infected adults in Addis Ababa: A cross-sectional study

BACKGROUND

Both under- and over-nutrition may occur among human immunodeficiency virus (HIV)-infected individuals and impact on the course of the acquired immune deficiency syndrome (AIDS) and its management due to the close interaction between immunity and nutrition. We investigated occurrence of undernutrition, excess weight and lipid abnormalities among antiretroviral naïve HIV-infected adults in Addis Ababa, Ethiopia.

METHODS

A cross-sectional study on 594 antiretroviral therapy (ART) naïve HIV-infected adults was conducted in four hospitals in Addis Ababa from February to September 2013. Hematological parameters (CD4+ T cell count and hemoglobin concentration), fasting serum glucose, total cholesterol (TC) and triglycerides (TG) were determined. Information on socio-demographic, anthropometric and World Health Organization (WHO) clinical stages was collected from patient clinical records, and triangulated by structured questionnaire. Height and weight measurements were taken and body mass index (BMI), undernutrition (BMI <18.5 kg/m2) and excess weight (BMI ≥25 kg/m2) determined. Statistical comparisons were made to identify significant factors associated with nutritional status and lipid profiles.

RESULTS

The prevalence of undernutrition was 15.1%, and the prevalence of excess weight was 22.1%, including 5.4% who were obese. The prevalence of hypercholesterolemia was 16.6% and it was higher in women (18.9%) than in men (11.0%) (p<0.05). However, the prevalence of hypertriglyceridemia was 29.8%. There was significant positive Spearman correlation between CD4+ T cell count and serum TC (r = 0.210, p<0.001), but no correlation was observed between CD4+ T cell count and TG (r = -0.007, p>0.05). Age categories 30-39 and 40-79, and WHO clinical stages III/IV for undernutrition; age categories 30-39 and 40-79, WHO clinical stages III/IV and TC ≥200 mg/dL for excess weight; and being female, age categories 30-39 and 40-79, and hypertriglyceridemia for hypercholesterolemia were found to be independent predictors by binomial logistic regression analysis.

CONCLUSION

Undernutrition, excess weight, hypercholesterolemia and hypertriglyceridemia were variably prevalent in ART naïve HIV-infected populations. This emphasizes the need for targeted nutritional programs as an integral part of HIV/AIDS care. Lipid levels need to be monitored regularly in patients whether on or off ART. In addition, improvement on household income and positive change in lifestyle and/or nutritional treatment to reduce morbidity and mortality are necessary interventions in HIV/AIDs patient management.

Effects of undernutrition on survival of human immunodeficiency virus positive children on antiretroviral therapy

Background

The relationship between undernutrition and HIV is bidirectional, ultimately contributing to quality of life and survival of affected individuals. Ethiopia is a sub-Saharan nation influenced by both undernutrition and HIV. In Ethiopia, although individuals are often dually impacted, the effect of undernutrition on the survival of HIV positive children on anti-retroviral therapy (ART) has not been well investigated. Therefore, this study assessed the effect of undernutrition on survival rates of HIV positive children on ART in Amhara Regional State of Ethiopia.

Methods

An institution-based retrospective cohort study was conducted among 390 HIV positive children on ART from the 1st of January, 2012 to the 28th of February, 2017 in Amhara Regional State Referral Hospitals. A simple random sampling technique was used to select the study participants. Data were extracted by reviewing patients’ ART intake and follow-up forms. Data were entered into Epi-Data Version 3.1, and analysis was done using STATA Version 13. The Kaplan-Meier survival curve was used to estimate the cumulative survival time of the sample. Log rank tests were employed to compare the survival time between different categories of explanatory variables. Bivariable and multivariable Cox proportional hazards models were fitted to identify predictors of mortality.

Results

Among the 390 records included in the final analysis, 9.7% of the individuals died within the follow-up period. In this study, the overall mortality rate was found to be 4.4 per 100 child-years (95% CI: 3.2, 6.0) while undernourished children had a lower survival time than well-nourished children. Low hemoglobin level (AHR: 3.2, 95% CI: 1.4, 7.4), CD4 cell count or percent below the threshold (AHR: 5.2, 95% CI: 1.9, 14.1), severe stunting (AHR: 3.9, 95% CI: 1.7, 9.4), severe wasting (AHR: 3.0, 95% CI: 1.3, 6.9) and advanced disease stage (III and IV) (AHR: 2.6, 95% CI: 1.1, 6.6) were found to be predictors of mortality.

Conclusion

There was a high rate of mortality. A significant difference was observed in the survival rate of undernourished and well-nourished children. Low hemoglobin level, CD4 count or percent below the threshold, severe wasting, severe stunting, and advanced disease stage were found to be predictors of mortality.

Brief Report: Weight Gain in Persons With HIV Switched From Efavirenz-Based to Integrase Strand Transfer Inhibitor-Based Regimens

BACKGROUND

With the introduction of integrase strand transfer inhibitor (INSTI)-based antiretroviral therapy, persons living with HIV have a potent new treatment option. Recently, providers at our large treatment clinic noted weight gain in several patients who switched from efavirenz/tenofovir disoproxil fumarate/emtricitabine (EFV/TDF/FTC) to dolutegravir/abacavir/lamivudine (DTG/ABC/3TC). In this study, we evaluated weight change in patients with sustained virologic suppression who switched from EFV/TDF/FTC to an INSTI-containing regimen.

METHODS

We performed a retrospective observational cohort study among adults on EFV/TDF/FTC for at least 2 years who had virologic suppression. We assessed weight change over 18 months in patients who switched from EFV/TDF/FTC to an INSTI-containing regimen or a protease inhibitor (PI)-containing regimen versus those on EFV/TDF/FTC over the same period. In a subgroup analysis, we compared patients switched to DTG/ABC/3TC versus raltegravir- or elvitegravir-containing regimens.

RESULTS

A total of 495 patients were included: 136 who switched from EFV/TDF/FTC to an INSTI-containing regimen and 34 switched to a PI-containing regimen. Patients switched to an INSTI-containing regimen gained an average of 2.9 kg at 18 months compared with 0.9 kg among those continued on EFV/TDF/FTC (P = 0.003), whereas those switched to a PI regimen gained 0.7 kg (P = 0.81). Among INSTI regimens, those switched to DTG/ABC/3TC gained the most weight at 18 months (5.3 kg, P = 0.001 compared with EFV/TDF/FTC).

CONCLUSION

Adults living with HIV with viral suppression gained significantly more weight after switching from daily, fixed-dose EFV/TDF/FTC to an INSTI-based regimen compared with those remaining on EFV/TDF/FTC. This weight gain was greatest among patients switching to DTG/ABC/3TC.

Mortality and Its Predictors among HIV Infected Patients Taking Antiretroviral Treatment in Ethiopia: A Systematic Review

Background

Even though the benefit of antiretroviral therapy (ART) is well established, there is a regional variation in the extent of its benefit. The aim of this review is to highlight mortality and its predictors in Ethiopian adult HIV patients who were on ART.

Methods

Relevant articles were searched on PubMed and Google Scholar databases. The search terms used in different combinations were predictor/determinant/factors, mortality/death/survival, HIV, ART/HAART, and Ethiopia.

Result

5-40.8% of the patients died during the follow-up period. More than half (50-68.8%) of the deaths occurred within 6 months of initiating ART. Advanced stage disease (stage III and stage IV), nonworking functional status (bedridden and ambulatory), low baseline CD4 count, low baseline hemoglobin level, TB coinfection, lower baseline weight, and poor treatment adherence were commonly identified as predictors of death in HIV patients.

Conclusion

5-40.8% of HIV patients in Ethiopia die in 2-5 years of initiating antiretroviral treatment. Most of the deaths in HIV patients occur early in the course of treatment. Special emphasis should be given for patients with advanced stage disease, nonworking functional status, low baseline CD4 count, low baseline hemoglobin level, TB coinfection, lower baseline weight, and poor treatment adherence.

CD4 Lymphocyte Enumeration and Hemoglobin Assessment Aid for Priority Decisions: A Multisite Evaluation of the BD FACSPresto™ System

Background:

The BD FACSPresto^™ system uses capillary and venous blood to measure CD4 absolute counts (CD4), %CD4 in lymphocytes, and hemoglobin (Hb) in approximately 25 minutes. CD4 cell count is used with portable CD4 counters in resource-limited settings to manage HIV/AIDS patients. A method comparison was performed using capillary and venous samples from seven clinical laboratories in five countries. The BD FACSPresto system was assessed for variability between laboratory, instrument/operators, cartridge lots and within-run at four sites.

Methods:

Samples were collected under approved voluntary consent. EDTA-anticoagulated venous samples were tested for CD4 and %CD4 T cells using the gold-standard BD FACSCalibur^™ system, and for Hb, using the Sysmex^® KX-21N^™ analyzer. Venous and capillary samples were tested on the BD FACSPresto system. Matched data was analyzed for bias (Deming linear regression and Bland-Altman methods), and for concordance around the clinical decision point. The coefficient of variation was estimated per site, instrument/operator, cartridge-lot and between-runs.

Results:

For method comparison, 93% of the 720 samples were from HIV-positive and 7% from HIV-negative or normal subjects. CD4 and %CD4 T cells venous and capillary results gave slopes within 0.96–1.05 and R² ≥0.96; Hb slopes were ≥1.00 and R² ≥0.89. Variability across sites/operators gave %CV <5.8% for CD4 counts, <1.9% for %CD4 and <3.2% for Hb. The total %CV was <7.7% across instrument/cartridge lot.

Conclusion:

The BD FACSPresto system provides accurate, reliable, precise CD4/%CD4/Hb results compared to gold-standard methods, irrespective of venous or capillary blood sampling. The data showed good agreement between the BD FACSPresto, BD FACSCalibur and Sysmex systems.

Risk factors for early mortality on antiretroviral therapy in advanced HIV-infected adults

BACKGROUND

Many HIV-infected individuals present with advanced HIV disease. These patients are at high risk of death after antiretroviral therapy (ART) initiation, but risk factors for death in these patients are unclear.

METHODS

We used data from a multisite randomized trial comparing empiric vs. preventive tuberculosis therapy in HIV-infected adults initiating ART with CD4 T-cell counts less than 50 cells/μl to evaluate risk factors for death within 48 weeks after ART initiation. Cox proportional hazards models were fit to evaluate characteristics present at baseline and at 4 weeks after ART initiation, including the week 4 CD4 T-cell response and new opportunistic infections.

RESULTS

Of 850 enrolled, the median pre-ART CD4 T-cell count was 18 cells/μl and 67 (7.9%) died. Baseline risk factors for death included lymphadenopathy, lower CD4 T-cell count, lower serum albumin, high white blood cell count, elevated neutrophil percentage, and lower hemoglobin. Among 746 participants with data at week 4, the median changes in CD4 T-cell count and viral load for those who died (n = 43) vs. survived were 26 vs. 56 cells/μl and -2.7 vs. -2.7 log10 copies/ml, respectively. Each 20 cell/μl lower change in week 4 CD4 T-cell count was associated with a 20% increased risk of post week-4 mortality (adjusted hazard ratio 1.20, 1.01-1.42, P = .038).

CONCLUSION

Evidence of active infection and suboptimal immunologic response during the first month of ART are associated with death in the first year after ART initiation in those with advanced HIV disease taking tuberculosis preventive therapy. Strategies to reduce early mortality in this population warrant further investigation.

The Nutritional Status of HIV-Infected US Adults

Background: Nutrition is critical to HIV mortality and morbidity. Improved treatment modalities have increased life expectancy of HIV-infected individuals. More than 1 million US adults are living with HIV, but little is known about their nutritional status. Objective: We aimed to characterize the nutritional status of those living with HIV with the use of the NHANES 2003-2014. Methods: The NHANES is a nationally representative, cross-sectional survey of the US population and includes a household interview, medical examination, and two 24-h dietary recalls; survey weights are applied to make the data nationally representative. HIV antibodies were ascertained initially by immunoassay and confirmed with Western blot. NHANES 2003-2014 data were analyzed for HIV-positive (n = 87) and HIV-negative (n = 15,868) US adults (aged 19-49 y). Body mass index (BMI), waist circumference, dietary intakes, and nutritional biomarkers were estimated and compared by HIV status, stratified by sex. Results: HIV-infected men and women had higher serum protein, lower serum albumin, and lower serum folate than did non-HIV-infected adults. HIV-positive women had significantly higher BMI, prevalence of overweight or obesity, and waist circumference risk and substantially lower serum 25-hydroxyvitamin D concentrations (44 compared with 65 nmol/L) than did HIV-negative women. When compared with HIV-negative women, HIV-positive women had lower intakes of some key nutrients such as fiber, vitamin E, vitamin K, magnesium, and potassium but had higher intakes of protein and niacin. Conclusions: The NHANES data suggest that HIV infection is associated with poorer markers of some nutritional status indicators; however, the US population prevalence of HIV is <0.5%. Given the small sample size, not only in this study but also in the United States, much more targeted research is needed to better understand the multitude of factors that influence the nutritional status among those living with HIV in the United States, especially among women.

Comparison of treatment adherence outcome among PLHIV enrolled in economic strengthening program with community control

Economic strengthening (ES) interventions are increasingly promoted to support the economic well-being and food security of people living with HIV (PLHIV) in resource poor settings. This study aims to assess the impact of ES interventions in Ethiopia designed to address poverty and food insecurity on antiretroviral treatment (ART) adherence. A comparative cross-sectional design was employed to compare treatment adherence between food insecure PLHIV benefitting from the ES project of WFP Ethiopia to food insecure PLHIV not participating in ES. Using the visual analogue scale (VAS) to measure ART adherence, only 9.9% of the ES group reported less than 95% adherence compared to 25.9% of the comparison group. Controlling for socio-economic and demographic variables using logistic regression models, engagement in ES activities increased the likelihood of having 95% or greater ART adherence by a factor of 2.4 and 5.6 respectively (as measured by VAS and ACTG approaches) compared to those PLHIV that were not engaged in ES. The findings of the study suggest that engagement in ES contributes to improved ART adherence among food insecure PLHIV. If further studies validate this result, ES should be adopted as a key strategy to improve HIV treatment adherence in resource poor settings where adherence is an issue of concern.

Prognostic markers in HIV mono-and co-infected individuals: A study from Karachi-Pakistan

BACKGROUND

Multiple infections are the most common problem among HIV infected individuals. The prognostic impact of these co infections in HIV-population in resource-limited countries like Pakistan has not been fully elucidated. The aim of this study was to assess CD4 and hemoglobin (Hb) levels in patients with HIV mono infection and HIV co-infection with Hepatitis C (HCV), Hepatitis B (HBV) and Mycobacterium tuberculosis (MTB).

METHODS

A total of 207 HIV positive patients were assessed for CD4 cells count and hemoglobin levels after confirmation of HIV by rapid tests as well as PCR. CD4 counts were performed via flow cytometry whereas hemoglobin levels were performed by Sysmex K-4500 auto-analyzer.

RESULTS

Out of 207 patients, 22 patients were found to be HIV mono-infected, while 185 patients were HIV positive along with co-infections of MTB or HCV or HBV. We found significant positive correlation between HB levels and CD4 count across the studied group (r=0.30 in HIV mono-infected group, r=0.23 in HIV co-infected group, p<0.05) at baseline. However, majority of the low hemoglobin levels (<8g/dl) and low CD4 count (<200cells/ul) cases were observed particularly in HIV/TB co-infections.

CONCLUSION

This study documents the prognostic value of hemoglobin assessment in HIV patients. The results indicate that decreasing Hb levels correlate with decreasing CD4 counts. It is emphasizing that Hb measurement may be used as an inexpensive surrogate marker as compared to CD4 analysis for disease progression in HIV patients. In addition, low Hb levels may also indicate presence of under lying co-infections, particularly, with M. tuberculosis (MTB).

Prevalence of Malnutrition and Associated Factors among Hospitalized Patients with Acquired Immunodeficiency Syndrome in Jimma University Specialized Hospital, Ethiopia

Background

HIV/AIDS predisposes to malnutrition. Malnutrition exacerbates HIV/AIDS progression resulting in increased morbidity and mortality. The magnitude of malnutrition in HIV/AIDS patients has not been well studied in Ethiopian setup. Our objective was to assess the prevalence of malnutrition and associated factors among HIV/AIDS patients admitted to Jimma University Specialized Hospital (JUSH).

Method

A cross-sectional study was conducted to assess the nutritional status of 109 HIV/AIDS patients admitted from November 2013 to July 2014. Cohort design was also used for outcome assessment. Serum levels of hemoglobin, albumin and CD4 counts were determined. Data were organized, coded, cleaned, entered into a computer and analyzed using SPSS version 16.0. Descriptive analysis was done initially. Those variables in the bivariate analysis with P-value < 0.25 were then considered as candidates to be included in the multivariable logistic regression model. A P-vale of < 0.05 was considered as statistically significant.

Results

The mean age of the patients was 32.7±8.12 with male to female ratio of 1:1.9. Patients were in either clinical stage, 3(46.8%), or stage, 4(53.2%). Forty nine (45%) of the respondents had a CD4 count of < 200 cells/µL. The overall prevalence of malnutrition was 46.8% (BMI<18.5kg/m2) and 44.1% (MUAC≤ 20cm). Eighty four (77.1%) of the patients had a serum albumin level of ≤3.5g/dl while 76 (69.6%) of the patients had anemia (Hg<12g/dl).

Conclusion

The prevalence of malnutrition was found to be high. WHO Stage 4 disease and CD4 count <200cells/µl were independent predictors of malnutrition.

Food Security in Households of People Living With Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome: A Cross-sectional Study in a Subdivision of Darjeeling District, West Bengal

OBJECTIVES

Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) adversely impacts food security in households of people living with HIV/AIDS (PLWHA). Little research has focused on food insecurity among PLWHA in India. The purpose of this study was to identify the prevalence of and factors relating to food security in households of PLWHA in the Siliguri subdivision of Darjeeling, West Bengal, India.

METHODS

A cross-sectional community-based study was carried out among 173 PLWHA residing in Siliguri and registered at the Anti-retroviral Therapy Centre of North Bengal Medical College & Hospital. Data was collected at the household level with interviews of PLWHA using a food security survey instrument. We analyzed the associations using logistic regression.

RESULTS

The prevalence of household food security among the participants was 50.9% (88/173). Five years or more of schooling, higher socioeconomic class and males were found to be significantly associated with a higher likelihood of food security. A later stage of the disease and the presence of other family members with HIV/AIDS were significantly associated with a lower likelihood of food security. The major coping strategies to deal with food insecurity in the acute phase HIV infection included borrowing money (56.1%), followed by spousal support, loans from microfinance institutions, banks, or money lenders, borrowing food, or selling agricultural products.

CONCLUSIONS

The present study revealed that only about half of households with PLWHA were food secure. Prior interventions relating to periods of food and economic crisis as well as strategies for sustaining food security and economic status are needed in this area.

Cash vs. food assistance to improve adherence to antiretroviral therapy among HIV-infected adults in Tanzania

OBJECTIVE

We evaluated the effectiveness of short-term cash and food assistance to improve adherence to antiretroviral therapy (ART) and retention in care among people living with HIV in Tanzania.

METHODS

At three clinics, 805 participants were randomized to three groups in a 3 : 3 : 1 ratio, stratified by site : nutrition assessment and counseling (NAC) and cash transfers (∼$11/month, n = 347), NAC and food baskets (n = 345), and NAC-only (comparison group, n = 113, clinicaltrials.gov NCT01957917). Eligible people living with HIV were at least 18 years, initiated ART 90 days or less prior, and food insecure. Cash or food was provided for 6 or less consecutive months, conditional on visit attendance. The primary outcome was medication possession ratio (MPR ≥ 95%) at 6 months. Secondary outcomes were appointment attendance and loss to follow-up (LTFU) at 6 and 12 months.

RESULTS

The primary intent-to-treat analysis included 800 participants. Achievement of MPR ≥ 95% at 6 months was higher in the NAC + cash group compared with NAC-only (85.0 vs. 63.4%), a 21.6 percentage point difference [95% confidence interval (CI): 9.8, 33.4, P < 0.01]. MPR ≥ 95% was also significantly higher in the NAC + food group vs. NAC-only (difference = 15.8, 95% CI: 3.8, 27.9, P < 0.01). When directly compared, MPR ≥ 95% was similar in the NAC + cash and NAC + food groups (difference = 5.7, 95% CI: -1.2, 12.7, P = 0.15). Compared with NAC-only, appointment attendance and LTFU were significantly higher in both the NAC + cash and NAC + food groups at 6 months. At 12 months, the effect of NAC + cash, but not NAC + food, on MPR ≥ 95% and retention was sustained.

CONCLUSION

Short-term conditional cash and food assistance improves ART possession and appointment attendance and reduces LTFU among food-insecure ART initiates in Tanzania.

Anthropometric Improvement among HIV Infected Pre-School Children Following Initiation of First Line Anti-Retroviral Therapy: Implications for Follow Up

BACKGROUND

Antiretroviral therapy (ART) is a lifesaving intervention for HIV infected children. There is a scarcity of data on immunological recovery and its relation with growth indicators among HIV infected young children. The current study aims to assess the pattern of anthropometric Z-score improvement following initiation of first-line ART among under-five children and the relationship between anthropometric Z-score improvement and immunologic recovery.

METHODS

We included under-five children who were on first-line ART at five major hospitals in Addis Ababa, Ethiopia. We measured anthropometry and collected clinical and laboratory data at follow up, and we retrieved clinical and anthropometric data at ART initiation from records. Z-scores for each of the anthropometric indices were calculated based on WHO growth standards using ENA for SMART 2011 software. Linear regression was used to assess the relationship between time on ART and anthropometric Z-score improvement; and the relationship between anthropometric Z-score improvement and immunologic recovery. Multiple linear regression was used to assess the independent predictors of anthropometric Z-score change.

RESULTS

The median age of the participants was 4.1 (Interquartile range (IQR): 3.3-4.9) years. More than half (52.48%) were female. The median duration of follow up was 1.69 (IQR: 1.08-2.63) years. There was a significant improvement in all anthropometric indices at any follow up after initiation of first-line ART (underweight; 39.5% vs16.5%, stunting; 71.3% vs 62.9% and wasting; 16.3% vs 1.0%; p-value< 0.0001). There was an inverse relationship between improvement in weight for age Z-score (WAZ) and duration of ART (R2 = 0.04; F (1, 158); p = 0.013). Height for age Z-score (HAZ) both at the time of ART initiation and follow up has a positive linear relationship with CD4 percentage at follow up (Coef. = 1.92; R2 = 0.05; p-value = 0.002). Duration on ART (Std. Err. = 0.206, t = -1.99, p-value = 0.049) and level of maternal education (Std. Err. = 0.290, t = 2.64, p-value = 0.009) were the only independent predictors of the change in WAZ and change in HAZ at any follow up visit respectively.

CONCLUSION

There was a significant improvement in all anthropometric indices at any follow-up after initiation of first-line ART among under-five children. HAZ was linearly related with immunologic recovery following ART initiation. The findings indicate that anthropometric indices could be taken as proxy indicators of immunologic recovery for under-five children.

Pre-ART nutritional status and its association with mortality in adult patients enrolled on ART at Fiche Hospital in North Shoa, Oromia region, Ethiopia: a retrospective cohort study

BACKGROUND

Human immunodeficiency virus (HIV) compromises the nutritional status of infected individuals and in turn, malnutrition worsens the effects of the infection itself by weakening the immune system consequently accelerating disease progression and death. However, few studies have examined the association between nutritional status at antiretroviral therapy (ART) initiation and early mortality. Therefore, this study assesses pre-ART nutritional status and other baseline characteristics and mortality among adult patients on ART at Fiche Hospital, Ethiopia.

METHODS

A retrospective cohort study was conducted among 489 ART enrolled adult patients between August 01, 2006 and September 30, 2013 in Fiche Hospital. Study participants were selected by using systematic random sampling method. Actuarial table was used to estimate survival of patients after ART initiation and log rank test was used to compare the survival curves. Cox proportional-hazard regression was used to determine independent predictors of time to death.

RESULTS

Most of the study subjects were females 254 (51.9%). A total of 489 patients were included in the analysis, of whom 87 died during a median study follow-up of 22 months. The estimated mortality among malnourished was 21, 28, 33, and 38% at 5, 10, 15, and 25 months respectively with mortality incidence density of 5.63 deaths per 100 person years. The independent predictors of mortality were: BMI <18.5 kg/m² (AHR = 5.4 95% CI 3.03-9.58), baseline ambulatory functional status (AHR = 3.84; 95% CI 2.19-6.74), bedridden functional status (AHR = 4.78; 95% CI 2.14-10.65), WHO clinical stage III (AHR 2.21; 95% CI 1.16-4.21), WHO clinical stage IV (AHR 4.05; 95% CI 1.50-10.97) and CD4 count less than 200 cells/μl (AHR = 2.95; 95% CI 1.48-5.88), two and more opportunistic infections (AHR 2.30; 95% CI 1.11-4.75).

CONCLUSIONS

Undernutrition at the time of ART initiation was associated with increased risk of death, particularly during the first 3 months after ART initiation. Interventions to promote earlier HIV diagnosis and treatment and integrating nutrition counseling at all stages of ART implementation may improve ART outcomes in this vulnerable population.

Frequency and distribution patterns of opportunistic infections associated with HIV/AIDS in Uganda

Background

We conducted a study to assess the frequency and distribution patterns of selected opportunistic infections (OIs) and opportunistic cancers (OCs) in different geographical areas before and after HAART in Uganda.

Methods

This was a cross-sectional serial review of observation data for adult HIV positive patients (≥15 years) enrolled with the AIDS support organization (TASO) in Uganda covering the period from January 2001 to December 2013. Both AIDS defining OIs/OCs and non-AIDS defining OIs were analyzed. The study period was structured into three time periods: “pre- HAART” (2001–2003), “early-HAART” (2004–2008) and “late-HAART” (2009–2013). Descriptive statistics were used to summarize the data by time period, age, gender and geographical location. Chi squared test used to test the significance of the differences in proportions.

Results

A total of 108,619 HIV positive patients were included in the analysis. 64% (64,240) were female with median age of 33 years (IQR 27–40). The most frequent OIs before HAART were oral candida (34.6%) diarrhoeal infection (<1 month) (30.6%), geohelminths (26.5%), Mycobacterium tuberculosis (TB) (17.7%), malaria (15.1%) and bacterial pneumonia (11.2%). In early HAART (2004–2008), the most frequent OIs were geohelminths (32.4%), diarrhoeal infection (25.6%), TB (18.2%) and oral candida (18.1%). In late HAART (2009–2013), the most frequent OIs were geohelminths (23.5%) and diarrhoeal infection (14.3%). By gender, prevalence was consistently higher in women (p < 0.05) before and after HAART for geohelminths, candidiasis, diarrhoeal infection, bacterial pneumonia and genital ulcer disease but consistently higher in men for TB and Kaposi’s sarcoma (p < 0.05). By age, prevalence was consistently higher in older age groups (>30 years) before and after HAART for oral candida and TB (p < 0.05) and higher in young age groups (<30 years) for malaria and genital ulcers (p < 0.05). By geographical location, prevalence was consistently higher in Eastern and Northern Uganda before and after HAART for diarrheal infection and geohelminths (p < 0.0001).

Conclusions

The frequency and pattern of OIs before and after HAART differs by gender, age and geographical location. Prevalence of geohelminths and diarrhea infection(<1 month) remains high especially in Northern and Eastern Uganda even after HAART and should therefore be given special attention in HIV/AIDS care programmes in these settings.

Nutritional status and its effect on treatment outcome among HIV infected clients receiving HAART in Ethiopia: a cohort study

Purposes

The aim of this study was to determine the effects of nutritional status at the start of highly active anti-retroviral therapy on treatment outcomes among HIV/AIDS patients taking HAART at Jimma University Specialized Hospital.

Methods

We performed a retrospective cohort study involving 340 adults who started highly active anti-retroviral therapy. The patients have been clinically followed for 2 years. Data were extracted from paper based medical charts by trained data collectors from January 30 to February 28, 2014 using data collection format. We entered data into Epi data version 3.1 and then exported to SPSS for windows version 21. Predictors of CD4 change were identified using multivariable linear regression model. Time to an event (death) was estimated by Kaplan–Meier and predictors of mortality were identified by Cox proportional hazard model.

Results

Out of 340 patients, 42 patients died during the follow-up. Twenty-five (59.5 %) deaths were from malnourished group. Age, baseline CD4, sex, baseline HAART and marital status were significant predictors of immunologic recovery at different time points. Malnutrition was associated with lower CD4 recovery and greater hazard of death.

Conclusions

Malnutrition tends to decrease CD4 recovery and predisposes patient to early death.

Forecast analysis of any opportunistic infection among HIV positive individuals on antiretroviral therapy in Uganda

Background

Predicting future prevalence of any opportunistic infection (OI) among persons infected with the human immunodeficiency virus (HIV) on highly active antiretroviral therapy (HAART) in resource poor settings is important for proper planning, advocacy and resource allocation. We conducted a study to forecast 5-years prevalence of any OI among HIV-infected individuals on HAART in Uganda.

Methods

Monthly observational data collected over a 10-years period (2004–2013) by the AIDS support organization (TASO) in Uganda were used to forecast 5-years annual prevalence of any OI covering the period 2014–2018. The OIs considered include 14 AIDS-defining OIs, two non-AIDS defining OIs (malaria & geohelminths) and HIV-associated Kaposi’s sarcoma. Box-Jenkins autoregressive integrated moving average (ARIMA) forecasting methodology was used.

Results

Between 2004 and 2013, a total of 36,133 HIV patients were enrolled on HAART of which two thirds (66 %) were female. Mean annual prevalence for any OI in 2004 was 57.6 % and in 2013 was 27.5 % (X²_trend = 122, b = −0.0283, p <0.0001). ARIMA (1, 1, 1) model was the most parsimonious and best fit for the data. The forecasted mean annual prevalence of any OI was 26.1 % (95 % CI 21.1–31.0 %) in 2014 and 15.3 % (95 % CI 10.4–20.3 %) in 2018.

Conclusions

While the prevalence of any OI among HIV positive individuals on HAART in Uganda is expected to decrease overall, it’s unlikely that OIs will be completely eliminated in the foreseeable future. There is therefore need for continued efforts in prevention and control of opportunistic infections in all HIV/AIDS care programmes in these settings.

Clinical Evaluation of the BD FACSPresto™ Near-Patient CD4 Counter in Kenya

BACKGROUND

The BD FACSPresto™ Near-Patient CD4 Counter was developed to expand HIV/AIDS management in resource-limited settings. It measures absolute CD4 counts (AbsCD4), percent CD4 (%CD4), and hemoglobin (Hb) from a single drop of capillary or venous blood in approximately 23 minutes, with throughput of 10 samples per hour. We assessed the performance of the BD FACSPresto system, evaluating accuracy, stability, linearity, precision, and reference intervals using capillary and venous blood at KEMRI/CDC HIV-research laboratory, Kisumu, Kenya, and precision and linearity at BD Biosciences, California, USA.

METHODS

For accuracy, venous samples were tested using the BD FACSCalibur™ instrument with BD Tritest™ CD3/CD4/CD45 reagent, BD Trucount™ tubes, and BD Multiset™ software for AbsCD4 and %CD4, and the Sysmex™ KX-21N for Hb. Stability studies evaluated duration of staining (18-120-minute incubation), and effects of venous blood storage <6-24 hours post-draw. A normal cohort was tested for reference intervals. Precision covered multiple days, operators, and instruments. Linearity required mixing two pools of samples, to obtain evenly spaced concentrations for AbsCD4, total lymphocytes, and Hb.

RESULTS

AbsCD4 and %CD4 venous/capillary (N = 189/ N = 162) accuracy results gave Deming regression slopes within 0.97-1.03 and R2 ≥0.96. For Hb, Deming regression results were R2 ≥0.94 and slope ≥0.94 for both venous and capillary samples. Stability varied within 10% 2 hours after staining and for venous blood stored less than 24 hours. Reference intervals results showed that gender-but not age-differences were statistically significant (p<0.05). Precision results had <3.5% coefficient of variation for AbsCD4, %CD4, and Hb, except for low AbsCD4 samples (<6.8%). Linearity was 42-4,897 cells/μL for AbsCD4, 182-11,704 cells/μL for total lymphocytes, and 2-24 g/dL for Hb.

CONCLUSIONS

The BD FACSPresto system provides accurate, precise clinical results for capillary or venous blood samples and is suitable for near-patient CD4 testing.

Undernutrition and associated factors among adults living with Human Immune Deficiency Virus in Dembia District, northwest Ethiopia: an institution based cross-sectional study

Background

Appropriate dietary intake determines the disease progression and success of Anti-Retroviral Therapy (ART). Undernutrition unacceptably increases the risk of mortality among adults living with Human Immune Deficiency Virus (HIV). However in resource limited settings including Ethiopia, many of HIV positive clients lack access to sufficient quantities of nutritious food. There is limited evidences showing the magnitude of undernutrition in this segment of the community, particularly in the rural residents. Therefore, this study aimed to assess undernutrition and associated factors among HIV positive adults attending ART clinic in Dembia District.

Methods

An institution based cross-sectional study was conducted in Dembia District from October 1 to 30, 2015. Systematic random sampling technique was used to recruit the study subjects. The anthropometric measurement, Body Mass Index, was computed to determine the nutritional status of the study participants. In order to identify factors associated with undernutrition a multivariable logistic regression analysis was employed. The Adjusted Odds Ratio (AOR) with 95 % Confidence Interval (CI) was calculated to show the strength of association. In multivariable analysis, variables with a P-value of <0.05 were considered as statistically significant.

Results

Of the study participants, about 23.2 % [95 % CI: 19.2, 27.2 %] were undernourished in Dembia District. The result of adjusted analysis revealed that, the odds of undernutrition was higher among adults whose age ranged between 18-29 years [AOR = 2.50, 95 % CI: 1.10, 5.69], who had a Cluster of Differentiation (CD)4 count less than 200 cells/mm³ [AOR = 6.21, 95 % CI: 2.97, 12.98), were widowed [AOR = 2.18, 95 % CI: 1.08,4.40), and anemic [AOR = 3.17, 95 % CI: 1.70, 5.92].

Conclusions

The prevalence of undernutrition among HIV positive adults was higher in the study area. Furthermore, being in the age range of 18-29 years, widowed, anemic, and having a CD4 count of less than 200 cells/mm³ were positively associated with undernutrition. Therefore, efforts should be strengthened to mitigate the higher burden of undernutrition by considering the identified determinants.

Daily consumption of ready-to-use peanut-based therapeutic food increased fat free mass, improved anemic status but has no impact on the zinc status of people living with HIV/AIDS: a randomized controlled trial

Background

Food insecurity in sub-Saharan Africa and malnutrition constitute the main obstacles for successful treatment of people living with HIV/AIDS (PLWH). The aim of this study was to assess the effect of consuming daily 100 g RUTF (ready-to-use therapeutic food) as supplement, on body composition, anemia and zinc status of hospitalized PLWH in Senegal.

Methods

A Controlled clinical trial was conducted in 65 PLWH randomly allocated to receive either standard hospital diet alone (Control group: n = 33), or the standard diet supplemented with 100 g RUTF/day (RUTF group: n = 32). Supplementation was continued at home during 9 weeks. Individual dietary intakes were measured and compared to the Recommended Dietary Allowances. Body composition was determined using Bio-Impedance Analysis. Hemoglobin was measured by HemoCue and plasma zinc (PZ) concentration by atomic absorption spectrometry. PZ was adjusted to infection (CRP and α1-AGP). All measures were conducted on admission, discharge and after 9 weeks home-based follow up.

Results

34 and 24 % of the patients in RUTF and Control groups were suffering from severe malnutrition (BMI < 16 kg/m²), respectively. In both groups, more than 90 % were anemic and zinc deficiency affected over 50 % of the patients. Food consumed by the Control group represented 75, 14 and 55 % of their daily recommended intake (DRI) of energy, iron and zinc, respectively. When 100 g of RUTF was consumed with the standard diet, the DRI of energy and zinc were 100 % covered (2147 kcal, 10.4 mg, respectively), but not iron (2.9 mg). After 9 weeks of supplementation, body weight, and fat-free mass increased significantly by +11 % (p = 0.033), and +11.8 % (p = 0.033) in the RUTF group, but not in the Control group, while percentage body fat was comparable between groups (p = 0.888). In the RUTF group, fat free mass gain is higher in the patients on ART (+11.7 %, n = 14; p = 0.0001) than in those without ART (+6.2 %, n = 6; p = 0.032). Anemia decreased significantly with the supplementation, but zinc status, measured using plasma zinc concentration, remained unchanged.

Conclusion

Improving PLWH’ diet with 100 g RUTF for a long period has a positive impact on muscle mass and anemia but not on the zinc status of the patients.
