Anemia and growth failure among HIV-infected children in India: a retrospective analysis

Incidence of anemia and predictors among Human Immunodeficiency Virus-infected children on antiretroviral therapy at public health facilities of Bahir Dar City, Northwest Ethiopia: multicenter retrospective follow up study

Background

Anemia is one of the common hematological problems among HIV-infected children. It impairs physical functioning, affects the quality of life, increases HIV progression, and decreases survival of HIV-infected children. In Ethiopia, limited studies were conducted on the incidence and predictors of anemia among HIV-infected children on antiretroviral therapy (ART). Therefore, this study aims to assess the incidence of anemia and predictors among HIV- infected children on ART at public health facilities of Bahir Dar City, Northwest Ethiopia.

Methods

An institution-based retrospective follow-up study was conducted among 403 HIV- infected children who have followed at ART clinics in public health facilities of Bahir Dar City from 2010 to 2020. A simple random sampling technique was employed to select the study units. Data was entered using Epi-data version 4.6 and analyzed using STATA 14.0. Cox proportional hazard model assumption was checked graphically and by scaled Schoenfeld residual test. Bivariable Cox-proportional hazards regression model was employed for each explanatory variable to check the association with the outcome variable. Variables with a p-value of < 0.2 in the bivariable analysis were candidates to the multivariable proportional hazard model. Cox proportional hazards model was used at a 5% level of significance to identify predictors of anemia.

Results

The overall follow up time was 1587 person–years. The overall incidence density of anemia was 6.87 with 95% confidence interval (CI) = (5.60, 8.16) per 100 person-years. The independent predictors show an association were child age from 0.25 to 5 years adjusted hazard ratio (AHR) = (1.83; 95% CI = 1.22, 2.77), World health organization clinical stage III and IV (AHR = 1.80; 95% CI = 1.22, 2.67), being underweight (AHR = 1.5; 95% CI = 1.01, 2.26), having fair/poor adherence to anti-retroviral therapy (AHR = 1.75; 95% CI = 1.08, 2.85) and zidovidine based anti -retroviral therapy regimen (AHR = 1.72; 95% CI = 1.12, 2.64).

Conclusion

The overall incidence rate of anemia was high compared to other country reports. Age, clinical, and ART-related variables provoked the incidence of anemia. Therefore, a need to emphasize the younger age group, prevent and manage opportunistic infections of WHO clinical stage III and IV, and select and monitor appropriate ART regimen types.

Under-nutrition and associated factors among children infected with human immunodeficiency virus in sub-Saharan Africa: a systematic review and meta-analysis

BACKGROUND

In the developing world, such as the sub-Saharan African region, HIV/AIDS has worsened the impact of under-nutrition in children. HIV infected children are highly vulnerable to under-nutrition. Therefore, 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 sub-Saharan Africa.

METHODS

The primary studies for this review were retrieved from PubMed/ MEDLINE online, Science Direct, Hinari, web of science, CINHAL, EMBASE, WHO databases, Google, and Google Scholar databases. The articles selected for this meta-analysis were published between 2010 and 2020. The last search date was 18 October 2021. The data was extracted in Microsoft Excel format and exported to STATA Version 14.0. A random effect meta-analysis model was used. Heterogeneity was evaluated by the I2 test. The Egger weighted regression test was used to assess publication bias.

RESULTS

We retrieved 847 records from these databases. Of which records, 813 were excluded due to different reasons and 34 studies were included in the final analysis. The pooled prevalence of stunting, underweight and wasting in HIV infected children was 46.7% (95% CI; 40.36-53.07, I2 = 98.7%, p < 0.01), 35.9% (95% CI; 30.79-41.02, I2 = 97.4% p < 0.01), and 23.0% (95% CI; 18.67-27.42, I2 = 96.9%, p < 0.01) respectively. The advanced WHO HIV/AIDS clinical staging (III&IV) [OR = 6.74 (95%: 1.747, 26.021), I2 = 94.7%] and household food insecurity were associated with stunting [OR = 5.92 (95% CI 3.9, 8.87), I2 = 55.7%]. Low family economic status [OR = 4.737 (95% CI: 2.605, 8.614), I2 = 31.2%] and increased feeding frequency [OR = 0.323 (95% CI: 0.172, 0.605), I2 = 69.8%] were significantly associated with under-weight. Anemia [OR = 2.860 (95% CI: 1.636, 5.000), I2 = 74.8%] and diarrhea in the previous month [OR = 4.117 (95% CI: 2.876, 5.894), I2 = 0.0%] were also associated with wasting among HIV infected children in sub-Saharan Africa.

CONCLUSIONS

The pooled prevalence of under-nutrition among HIV infected children was high. Nutritional assessment and interventions need great attention as a part of HIV care for HIV positive children. The implementation of policies and strategies established by national and international stakeholders in ART care centres should take a maximum emphasis on reducing under-nutrition among HIV infected children.

Malnutrition in HIV infected children on antiretroviral drugs in a cohort of Ghanaian children

Background

HIV infected children are at increased risk of malnutrition which worsens the depressed immune system, leading to poor disease prognosis.

Aim

To assess the nutritional status of children between 6-12 years on antiretroviral drugs (ARV) at two health facilities in Accra.

Methods

The study design was cross sectional among children between 6 and 12 years being administered with antiretroviral drugs at two hospitals in Accra. A purposive sample of 100 children was used. Height and weight measurements were taken and used to compute z-scores for stunting, underweight and wasting. Haemoglobin status was obtained from their folders. A semi-structured questionnaire was used to obtain sociodemographic data and a 24-hour dietary intake used to assess nutrient intakes. Data was analyzed using IBM SPSS version 20.0. Nutrient analysis was done using Micro diet version 3.0. Data was summarized using means and percentages. Chi-squared test was used to test for associations and statistical significance set at p < 0.05.

Results

The prevalence of stunting, underweight and wasting was reported as 28%, 16% and 13% respectively. Girls were more stunted and wasted compared to boys. Mean haemoglobin concentration was 10.12 ± 2.77 g/dl. Mild, moderate and severe anaemia were reported in 14.2%, 41.1% and 12.5% of the children respectively. Apart from carbohydrates, less than 50% of the children were able to meet their requirements for the other nutrients”.

Conclusions

Our findings reveal high level of malnutrition among the children receiving ARV. There is the need for targeted nutrition interventions to improve the nutritional status of the children.

Anemia among children living with HIV/AIDS on HAART in Mekelle Hospital, Tigray regional state of northern ethiopia - a cross-sectional study

BACKGROUND

Anemia is a common complication of HIV/AIDS in children. There is lack of evidence on anemia prevalence among children living with HIV/AIDS on highly active antiretroviral therapy (HAART) in Tigray regional state, which the current study aimed to generate.

METHODS

An institution-based cross-sectional study was conducted on 241 children living with HIV/AIDS on HAART attending the antiretroviral therapy (ART) clinic of Mekelle hospital from November 2018-January 2019. Socio-demographic data were collected using a structured pretested questionnaire. Participants' hemoglobin level was utilized to determine the prevalence of anemia. WHO cut-off values for Hgb were used to categorise the severity of anemia. Microscopic examination was performed for morphological classification of anemia.

RESULTS

Among the participants, 7 % (n = 16) were anemic in this study. Of these, 56 %, 19 %, and 25 % had mild, moderate, and severe anemia, respectively. Morphologically, normocytic-normochromic anemia was found the most common type of anemia in this study.

CONCLUSIONS

The prevalence of anemia among participants was low in this study. However, a considerable proportion of participants had severe anemia, requiring regular monitoring of anemia status in these patients for better clinical outcomes and quality of life improvements.

<p>Incidence and Predictors of Anemia Among Children on Antiretroviral Therapy at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia, 2007–2017: A Retrospective Follow-Up Study</p>

Background

Anemia is the most common hematological abnormality among children on antiretroviral therapy. In Ethiopia, as far as our search, there are no studies done on the incidence and predictors of anemia among children on antiretroviral therapy. This study aimed to assess the incidence and predictors of anemia among children on antiretroviral therapy, attending antiretroviral therapy care at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia, from 2007 to 2017.

Methods

A retrospective follow-up study was conducted among 391 children on antiretroviral therapy. Mean survival time for children to be anemia free was estimated. A Log rank test was used to compare survival curves among different independent variables. The Cox regression model was used. The adjusted hazard ratio (AHR) with a 95% confidence interval (CI) was calculated. P-value ≤0.05 was considered as statically significant.

Results

The overall incidence rate of anemia was 10.5 (95% confidence interval (8.6, 12.8)) per 100 child-year. Being severe-immunosuppressed (AHR=2.9, 95% CI: 1.23–6.77), undernutrition (AHR =2.7, 95% CI: 1.5–5), taking zidovudine-based ART regimen (AHR =4, 95% CI: 1.23–12.9), and tuberculosis (AHR =2.1, 95% CI: 1.4–3.3) were independent predictors of anemia among children.

Conclusion

In this study, the incidence rate of anemia among children on antiretroviral therapy was found to be high. Tuberculosis, zidovudine-based drugs, severe immunosuppression, and undernutrition have remained statically significant predictors of anemia among children on antiretroviral therapy. Children with HIV were the most vulnerable group for anemia, especially in developing countries. Therefore, improving their nutritional status and considering other predictors of anemia were very important for children to reduce the incidence of anemia among children with HIV.

A systematic review and meta-analysis of the prevalence and predictors of anemia among children in Ethiopia

Background

Anemia is a wide-spread public health problem characterized by a decrease in hemoglobin concentration and/ or red blood cell volume below an established cut-off value. In developing countries including Ethiopia, about half of children are estimated to be anemic. Therefore, the purpose of this study was to determine the pooled prevalence of anemia and its predictor factors among children in Ethiopia.

Method

The studies were identified through explicit and exhaustive search of reputable databases (PubMed, Google scholar, Science Direct, EMBASE, Cochrane library, and the hand search of reference lists of previous prevalence studies to retrieve more related articles. Thirty-nine studies were selected based on a comprehensive list of inclusion and exclusion criteria. Data were extracted using a standardized and pre-tested data extraction checklist, and the analysis was done using STATA 14 statistical software. To assess heterogeneity, the Cochrane Q test statistic and I2 tests were used. In our analysis, considerable heterogeneity was observed. Therefore, a random effect meta-analysis model was used to estimate the pooled prevalence of anemia. Moreover, the predictor factors of anemia were examined.

Results

The forest plot of 39 included studies revealed that the overall pooled prevalence of anemia among children in Ethiopia was 34.4% (95% CI: 29.1, 39.7%). Sub-group analysis showed that the highest anemia prevalence was observed in Somali Region with a prevalence of 49.4 % (95% CI: 20.9, 77.8). Also, anemia in children was found to be highest in the age group of less than five years (45.2, 95% CI: 39.6,50.8). Low literacy of families: 1.3 (95% CI: 1.1, 1.7), low family socioeconomic status: 1.9 (95% CI: 1.1,3.01.3), having housewife mothers or with no job: 1.5 (95% CI: 1.4, 1.9) and rural residence: 3.3 (95% CI: 1.7,6.1) were found to be predictors of anemia among children.

Conclusion

In this study, one in three children were anemic in Ethiopia. It is a moderate public health problem in children in this study. Low literacy, low socioeconomic status as well as rural residence of the families and helminthic infection of the children were found to be predictors of anemia in the children. Community and school-based interventions should be strengthened to improve the problem.

Magnitude of Anemia and Associated Factors among HIV-Infected Children Receiving Antiretroviral Therapy in Pastoral Community, Ethiopia: A Retrospective Cross-Sectional Study

Background

The two major comrbidities (anemia and poor nutrition) are common manifestations of HIV-infected children, which threaten their lives. In Ethiopia, there is limited information on the magnitude and factors associated with anemia among HIV-infected children. Thus, this study was aimed to determine the magnitude and factors associated with anemia among HIV-infected children receiving antiretroviral therapy in the Afar region, Ethiopia.

Methods

A cross-sectional retrospective record review was conducted on a sample size of 102 HIV-infected children aged 6 months to < 15 years in selected ART sites of the Afar region from May 1 to 25, 2018. Patient cards from 2009 to 2017 with the required information were considered. A paired sample t-test was used to assess whether there is a significant difference in the hemoglobin level before and after the HAART regimen. Multivariable logistic regression was used to determine predictors of anemia. Statistical significance was determined atp value < 0.05.

Result

At baseline, 53.9% of study participants were anemic, from which 8.7%, 36.3%, and 9.8% were mild, moderate, and severe, respectively. There was a statistically significant improvement of hemoglobin level following the one-year course of ART treatment from 10.67 ± 1.82 to 11.5 ± 1.5 (p value ≤ 0.001): an improvement of 0.83 ± 1.74. Children who were moderately and severely stunted were more than five (AOR = 5.16, 95% CI (1.71, 15.56)) and more than twelve (AOR = 12.45, 95% CI (2.62, 59.21)) times more likely to be anemic than children who were not stunted, respectively. Children whose mothers had not attended ANC follow-up were more than three (AOR = 3.68, 95% CI (1.38, 9.81)) times more likely to be anemic than children whose mothers attended ANC. Children who were in clinical stages 3 and 4 were more than five (AOR = 5.07, 95% CI (1.79, 14.37)) times more likely to be anemic than children who were in clinical stage 1 and 2.

Conclusion

The magnitude of anemia among HIV-infected children was found to be high, which is 53.9%. Nutritional status (stunting), WHO clinical stage, and history of ANC follow-up were the predictors significantly associated with childhood anemia. Thus, interventions for HIV-infected children should consider those factors.

Magnitude of anemia and undernutrition among HIV-infected children who took HAART: a retrospective follow-up study

BACKGROUND

Human immunodeficiency virus (HIV) is a virus that affects the immune system, the body's natural defence system. It is a virus spreading through certain body fluids that attacks the body's immune system, specifically the Cluster of Differentiation 4 (CD4) T-cells. Anemia is a common manifestation of pediatric HIV infection and is a significant negative predictor of survival. Moreover, undernutrition is the underlying cause of death among 35% of children aged under 5 years, and it has been negatively implicated with antiretroviral therapy (ART) outcomes, particularly in developing countries. The aim of this study was to determine the magnitude of anemia and undernutrition among HIV-infected children within the first year of ART initiation at University of Gondar comprehensive specialized hospital ART clinic.

METHODS

Records of 200 children aged <15 years old who were on ART at the University of Gondar comprehensive specialized hospital from 2005 to 2017 were retrospectively reviewed in 2017. Baseline characteristics and one-year flow-up data after ART initiation were extracted from the medical records. Anemic status was determined based on the hemoglobin (Hb) level in accordance with World Health Organization (WHO) guideline. The nutritional status was calculated based on anthropometric measurements. Generalized Estimating Equation (GEE) was fitted to identify factors associated with anemia and undernutrition. Odds ratio with the corresponding 95% Confidence interval (CI) was reported.

RESULTS

Of the total children, 75 (37.5%) (95% CI: 30.73-44.27%) were anemic at the baseline of ART initiation. The magnitude of anemia has shown a persistent decline from the baseline to 12th months of ART initiation. At ART initiation, the magnitude of undernutrition was high, 64% (95% CI: 57.3-70.7%). Similarly, the magnitude of undernutrition showed decrement during a one year ART initiation period. Stunting was the most common type of undernutrition at baseline (49.5%), 6 months (44%), 9 months (41%), and 12 months (39%) of ART initiation. Baseline CD4 count, Baseline WHO clinical stage and age at enrollment to the care were significantly associated with anemia within the first year of ART initiation.

CONCLUSION

Despite a decline in the first year of ART initiation, anemia and undernutrition were public health problems in HIV-infected children. Hence, for HIV-infected children taking HAART, emphasis should be given to manage anemia and undernutrition within the first year of ART initiation.

Anemia, Iron Status, and HIV: A Systematic Review of the Evidence

People living with HIV (PLWHIV) are at high risk of anemia due to inadequate iron intake, HIV and opportunistic infections, and inflammation, and as a side effect of antiretroviral therapy. Though iron supplementation can reduce iron deficiency anemia (IDA) in the general population, its role in anemia and in the health of PLWHIV is unclear due to concerns that iron supplementation may increase HIV replication and risk of opportunistic infections. We systematically reviewed the evidence on indicators of iron status, iron intake, and clinical outcomes among adults and children with HIV. The evidence suggests that anemia is associated with an increased risk of all-cause mortality and incident tuberculosis among HIV-infected individuals, regardless of anemia type, and the magnitude of the risk is greater with more severe anemia. High serum ferritin is associated with adverse clinical outcomes, although it is unclear if this is due to high iron or inflammation from disease progression. One large observational study found an increased risk of all-cause mortality among HIV-infected adults if they received iron supplementation. Published randomized controlled trials of iron supplementation among PLWHIV tend to have small sample sizes and have been inconclusive in terms of effectiveness and safety. Large randomized trials exploring approaches to safely and effectively provide iron supplementation to PLWHIV are warranted.

Anemia and Related Factors Among Highly Active Antiretroviral Therapy Experienced Children in Hawassa Comprehensive Specialized Hospital, Southern Ethiopia: Emphasis on Patient Management

Background

Human Immunodeficiency Virus (HIV) and its therapy cause a variety of hematological abnormalities that have been known to be one of the most common causes of morbidity and mortality in HIV-positive children. One of the commonly observed hematologic manifestations in HIV-positive children is anemia and it has a multifactorial source. We intended to assess the prevalence, as well as its related factors of anemia among Highly Active Antiretroviral Therapy (HAART), experienced children.

Methods

A hospital-based cross-sectional study was employed at Hawassa comprehensive specialized hospital from February 15-June 15, 2018. Overall, 273 HAART-practiced children were included in the study. Socio-demographic variables and clinical data were collected using a standard and pretested questionnaire. Medical records were reviewed for each study participant using a standard checklist. Blood specimens were collected and examined for complete blood count, CD4 cell count and blood film for hemoparasites and morphological classification of anemia, whereas stool specimens were collected and examined for intestinal parasites. Data were entered into Epidata and transferred to SPSS (Statistical Package for Social Science) version 20 software. Descriptive analysis was done for prevalence and binary and multivariate logistic regression was used to determine factors associated with anemia. Statistical significance was stated at P-value<0.05.

Results

The overall prevalence of anemia in this study was 11.4%. Morphologically the predominant anemia was Normocytic Normochromic anemia which accounted for 64.5%. In the current study, children within the age group of <7years (AOR: 3, CI: 1.2-7.5, P=0.02), those who were rural residents (AOR: 2.6, CI: 1.0-6.6, P=0.042) and those with viral load >150 copies/mL (AOR: 3.4, CI: 1.36-8.3, P=0.009) were found to be significantly associated with anemia.

Conclusion

The prevalence of anemia in this study was 11.4%. It was significantly associated with different factors such as age, residence and viral load. Therefore, regular follow-up management should be emphasized for HAART-experienced children. Hence, there is a need for a longitudinal study to be conducted further to explore the causes of anemia due to HIV and the pattern of hemoglobin changes with HAART- experienced children will be very important.

Gross motor developmental delay in human immunodeficiency virus-infected children under 2 years of age

Background:

Human immunodeficiency virus (HIV) infection has significant effects on child development. We report the outcome of gross motor developmental assessment in HIV-infected children <2 years compared with that of uninfected children.

Materials and Methods:

Every child <2 years of age presenting for the first time to the pediatric outpatient department of the hospital over 3 months was studied. Each child had a physical examination with gross motor milestone assessment, as well as initial double rapid HIV antibody tests with confirmatory tests for those with positive or discordant results. Children with evidence of motor delay were booked for reassessment after 1 month. The milestone performance criteria of the Multicenter Growth Reference Study of the World Health Organization were used as a standard.

Results:

One hundred and eight children were studied. Male-to-female ratio was 1:1. Fourteen children (13.0%) were HIV infected. Nine children (8.3%) had delayed development of gross motor milestones, of which five were HIV infected and four were uninfected (P = 0.001). Each motor milestone was attained at a significantly later mean age by the HIV-infected children when compared to the uninfected. Evidence of delay in gross motor milestones was apparent by the first 6 months of life.

Conclusions:

A tendency to poorer motor development is apparent in young children infected by HIV and can manifest as early as the first 6 months of life. Routine HIV screening as well as early developmental assessment of all children should be encouraged.

Impact of Anemia on Outcome of HIV-Infected Pediatric Patients: A Prospective Observational Study

Introduction

Anemia has been widely reported to predict a poorer prognosis for HIV-infected patients, both in terms of progression to AIDS and in survival. This study aimed to determine the etiology of anemia and its immunological correlation in HIV-infected children.

Materials and Methods

Four hundred and eighty-nine HIV-infected children were screened, of which 86 HIV-infected children with anemia were enrolled. Standard WHO definitions were used for anemia, HIV staging, and growth parameters. Chi-square test, t-tests, and univariate and multivariate logistic regression analyses were used to analyze the data.

Results

Anemia was present in 17.58% (86/489) of HIV-infected children, including 84.6% with moderate anemia, 11.5% with severe anemia, and 2.32% with mild anemia. The mean hemoglobin (Hb) among patients with CD4 count <350 cell/mm³ was lower (7.90 g%) (standard deviation 1.48) compared to those having CD4 >350 cell/mm³ (P = 0.02). Children with severe immunological stage had a significantly lower mean Hb (adjusted estimate: -1.61, 95% confidence interval: -2.65, -0.56) compared to those who had normal immune status. No statistically significant differences in mean Hb at baseline when compared to various demographic and clinical characteristics were observed in unadjusted and adjusted regression models.

Conclusion

Hb is an easy and inexpensive tool to measure and can be used for monitoring disease progression in a resource-limited setting.

Increased monocyte activation with age among HIV-infected long term non-progressor children: implications for early treatment initiation

OBJECTIVES

The key to newer therapeutic and eradication approaches often lies in understanding slow disease progression in HIV infection. The paediatric population has been poorly studied in this regard. We aimed to describe a cohort of perinatally infected long-term nonprogressor (LTNP) children living with HIV in India and to evaluate the immune biomarkers of disease progression.

METHODS

LTNPs (ART-naïve, with a CD4 count ≥ 500 cells/μL at age ≥ 7 years) among the cohort of HIV-infected children were identified and monitored longitudinally, and their CD4 T-cell counts and plasma viral loads were measured every 6 months. The plasma monocyte/macrophage activation markers, namely soluble CD14 (sCD14), soluble CD163 (sCD163) and interferon-inducible protein-10 (IP-10) were measured by enzyme-linked immunosorbent assay (ELISA) in LTNPs and progressors. The Mann-Whitney U-test was used to compare the two groups and P values < 0.05 were considered statistically significant. Spearman's rank or Pearson's correlation coefficient (r) was calculated to determine the associations between variables.

RESULTS

Among 378 children living with HIV-1 surveyed in our cohort, 40 (10.6%) were LTNPs. Longitudinal analysis of the LTNP data showed that both CD4 count and viral load declined significantly with age (P < 0.0001 for both). Plasma sCD14 levels were significantly (P < 0.005) higher in progressors and sCD163 levels were significantly (P < 0.0001) higher in LTNPs.

CONCLUSIONS

The prevalence of LTNPs in our cohort of perinatally infected children living with HIV was 10.6%. We observed a trend for associations between the increasing sCD163 monocyte/macrophage activation marker levels, declining CD4 counts and the gradual loss of nonprogressor status with age in the LTNPs. These findings underscore the need for early antiretroviral therapy in those children with proven slow disease progression.

Growth in children infected with HIV receiving anti-retroviral therapy in Vietnam

BACKGROUND

There are currently two markers used to monitor treatment response to anti-retroviral therapy (ART) in HIV-infected children: CD4 T-cell count and HIV viral load; but analysis of these could be challenging in resource-poor countries. The aim of this study was therefore to determine whether change in growth parameters such as weight-for-age Z score (WAZ), height-for-age Z score (HAZ) and body mass index-for-age Z score (BMIZ) is associated with treatment response in HIV-infected children.

METHODS

This was a nested case-control study, in which the data were collected at enrolment and then periodically every 6 months for a total 36 month follow up of 107 HIV-infected children enrolled and treated at National Hospital of Pediatrics, Vietnam.

RESULTS

At treatment initiation, WAZ, HAZ and BMIZ were not significantly higher in the treatment success (TS) group compared with the treatment failure (TF) group. After ART initiation, WAZ and HAZ increased, and this was significant in the TS group (from -1.5 to -0.54, P < 0.01 and from -2.06 to -0.84, P < 0.01, respectively). Low HAZ was significantly associated with TF (HR, 0.71; 95% CI: 0.54-0.92).

CONCLUSION

Height-for-age Z score was the most sensitive growth parameter in prediction of the treatment response. In order to use growth parameters, particularly HAZ as a prognosis marker for TF in clinical practice, further research should be conducted to evaluate the role of growth parameters and their effects on treatment response.

Prevalence and risk factors of anemia among children aged 6-23 months in Huaihua, Hunan Province

Background

Anemia is one of the most common diseases of childhood and is a health problem globally, particularly in developing counties and in children less than 2 years of age. Anemia during childhood has short- and long-term effects on health. However, few studies have investigated the prevalence of anemia among children in Huaihua. Therefore, this study analyzed the prevalence and risk factors of anemia among children 6 to 23 months of age in Huaihua.

Methods

This cross-sectional study was conducted at a maternal and child health care hospital in Huaihua, from September to November 2017. The study population recruited using a multistage sampling technique. A structured questionnaire was used to collect data on the characteristics of the children and members of their families. Hemoglobin (Hb) levels were measured by using a microchemical reaction method. Logistic regression analysis was used to identify associated factors and odds ratio with 95% CI was computed to assess the strength of association.

Results

In total, 4450 children were included in this study. The prevalence of anemia was 29.73%. In multivariate logistic regression analysis, the results show that mother and father of Miao ethnicity (OR = 1.23 and 1.31), diarrhea in the previous 2 weeks (OR = 1.35), breastfeeding in the prior 24 h (OR = 1.50), and caregivers able to identify the optimum timing of complementary feeding (OR = 1.15) had positive correlations with anemia. However, children aged 18 to 23 months (OR = 0.55), father of Dong ethnicity (OR = 0.82), addition of milk powder once or twice (OR = 0.71), addition of infant formula once or twice, three times, and four or more times in the previous 24 h (OR = 0.72, 0.70, and 0.75), and addition of a nutrient sachet four or more times in the prior week (OR = 0.70) were negatively associated with anemia.

Conclusions

The prevalence of anemia among children 6 to 23 months of age in Huaihua was higher than that in more developed regions of China. The feeding practice of caregivers was associated with anemia. nutrition improvement projects are needed to reduce the burden of anemia among children in Huaihua.

Intergenerational influences on childhood anaemia

Prior research on assessing intergenerational influences on child anaemia has largely approached it from purely maternal perspective. Although there is much merit to focus on that, it is an extremely limited/reductionist view of understanding intergenerational influences. We expanded the intergenerational influences to include the fathers and overall of intergenerational household transfers. We analysed a sample of 19,619 mother-father-offspring trios from the 2015-2016 Indian National Fertility and Health Survey with available data on haemoglobin (Hb). Multinomial logistic regression models were used to establish associations between parent anaemia, household characteristics, and categories of offspring anaemia. Maternal and paternal Hb was measured as in children using a finger prick blood sample. The primary outcome was child's Hb level (in g/dl) and grades of anaemia defined as mild (10-10.9 g/dl), moderate (7-9.9 g/dl), and severe (<7 g/dl). Mean Hb was 10.1 g/dl for children, 14.2 g/dl among fathers, and 11.4 g/dl among mothers. Hb correlation was 0.1 between fathers and offspring and 0.2 between mothers and offspring (P < 0.001 for all correlations). Maternal-paternal Hb correlations were consistent across quintiles of wealth index. Maternal anaemia was associated with odds ratio of 1.3 (95% CI [1.1, 1.4]) and 1.6 (95% CI [1.4, 1.7]) for childhood mild and moderate/severe anaemia, respectively. Paternal mild anaemia was associated with an odds ratio of 1.1 (95% CI [0.9, 1.4]) and 1.4 (95% CI [1.2, 1.7]) for child moderate/severe anaemia. The clustering of poor circumstances suggests that public health strategies target social deprivation at the household level. A comprehensive perspective will provide holistic interventions to control childhood anaemia.

Hematological abnormalities in HIV-antiretroviral therapy naïve clients as seen at an immune suppression syndrome clinic at Mbarara Regional Referral Hospital, southwestern Uganda

Aim/objective

To assess the common hematological abnormalities among HIV-antiretroviral therapy (ART) naïve clients attending an immune suppression syndrome (ISS) clinic at Mbarara Regional Referral Hospital (MRRH), southwestern Uganda.

Patients and methods

This was a cross-sectional study carried out during the months of March to August 2016 at the ISS clinic of MRRH. We collected approximately 4.0 mL of EDTA anticoagulated blood samples, which were assayed for complete blood count, CD4+ cell count and thin film examination. Correlation of the hematological abnormalities with CD4+ cell counts was done using correlation coefficient (r) and analysis of variance (F), and the p-value was set at ≤0.05.

Results

A total of 141 clients were enrolled. Of these, 67.38% (95/141) were anemic, 26.24% (40/141) had thrombocytopenia while 26.95% (38/141) had leucopenia. Of the 95 participants with anemia, 89.47% (85/95) presented with normocytic-normochromic anemia, 8.42% (8/95) with microcytic-hypochromic anemia and 2.11% (2/95) with macrocytic-hypochromic anemia. Anemia was not different across the several World Health Organization (WHO) stages of HIV infection disease progression (p>0.05). Statistically significant differences were present among participants with leucopenia (p<0.05). Also, leucopenia was more prevalent (11/38) among participants in WHO stage 4 of HIV infection. CD4+ cell counts correlated with thrombocytopenia (r=0.24, p<0.05) and leucopenia (r=0.15, p<0.05).

Conclusion

People living with HIV/AIDS (PLWHIV/AIDS) ought to be routinely monitored and treated for the occurrence of hematological abnormalities. Early initiation of ART can help to prevent some hematological abnormalities.

Malnutrition among HIV infected children under 5 years of age at the Laquintinie hospital Douala, Cameroon

Introduction

The aim of this study was to assess the prevalence of malnutrition among HIV infected children under five years of age followed up at the Laquintinie Hospital Douala (LHD).

Methods

Medical records of children aged 13 days-59 months enrolled at initiation of antiretroviral treatment in the Day Care Unit/LHD, were reviewed for a period of 14 years (from 2002 to 2015). We used standard Z-scores, with cut-off point of <-2 SD to define low height-for-age (HAZ), low weight-for-height (WHZ) and low weight-for-age (WAZ). Factors associated with malnutrition were assessed according to World Health Organization (WHO) criteria.

Results

Overall, 217 medical records were included and 52.5% were records of boys. The median weight, height and age of the children was 9.5 kg (range: 2.5-20), 76 cm (range: 46- 117) and 22 months (range: 0.03-59), respectively. The overall prevalence of malnutrition among HIV-infected children was 68.7%; 63.6% were stunted (HAZ<-2), 37.8% were underweight (WAZ<-2) and 18.4 % were wasted (WHZ<-2). Severe and advanced immunological stages of HIV according to WHO were found in 42.4%, (39/92) and 17.4%, (16/92) of children respectively, and most of them (21.7%) were aged 12-36 months. The overall prevalence of anemia, oropharyngeal candidiasis and pulmonary tuberculosis were 34.6%, 12% and 8.8%, respectively. Oropharyngeal candidiasis was a risk factor independently associated with severe underweight and wasting (OR = 4.9, 95% CI: 1.8-13.5, p = 0.002) and (OR = 5.1, 95% CI: 1.5-17.1, p = 0.007).

Conclusion

HIV infection negatively affects the nutritional status of children under five years of age. Early detection of malnutrition is necessary and adequate nutrition should be integrated into the management of pediatric HIV.

Effect of Antiretroviral Therapy on Growth Parameters of Children With HIV Infection

BACKGROUND

Children living with HIV (CLHIV) commonly experience growth failure. We report growth parameters in CLHIV at baseline and during 3 years of antiretroviral therapy (ART).

METHODS

Records of CLHIV who had completed at least 3 years on ART were reviewed after excluding subjects who died, were lost to follow-up or developed treatment failure to assess impact of sustained administration of ART. Height-for-age (HFA) and body mass index for age (BFA) Z scores were calculated, and proportion of CLHIV with wasting and stunting estimated at baseline, 6, 12, 24 and 36 months after starting ART using the linear mixed model. Factors influencing significant changes in growth parameters were assessed.

RESULTS

HFA Z score improved steadily from -3.12 at baseline to -2.33 at 36 months of ART. The prevalence of stunting declined from 77.7% to 59.2% during this period. BFA Z scores improved from -1.2 at baseline to -0.4 at12 months on ART but declined to -1.0 at 36 months. The proportion of subjects with wasting was 29.3%, 9.7% and 16.7% at baseline, 12 and 36 months, respectively. Baseline clinical stage (1 + 2), absence of wasting and lower HFA Z score had significant positive influence on changes in HFA Z score, while younger age at ART initiation and a low baseline BFA Z score had a positive influence on catch-up in body mass index. Including data of children who died or developed treatment failure did not impact upon the results.

CONCLUSION

Majority of CLHIV are stunted at the start of ART. ART was only partially effective in countering malnutrition and growth failure in CLHIV.

Magnitude of cytopenias among HIV-infected children in Bahir Dar, northwest Ethiopia: a comparison of HAART-naïve and HAART-experienced children

Background

AIDS, caused by HIV, is a multisystem disease that affects hematopoiesis. The aim of this study was to assess cytopenias among HIV-infected children who had a follow-up at Felege Hiwot Referral Hospital, Bahir Dar, northwest Ethiopia.

Methods

An institution-based cross-sectional study was conducted between April and May 2013. Systematic random sampling method was used to select the study participants. Descriptive statistics, independent t-test as well as chi-square and logistic regression were used for analysis. A p-value <0.05 was considered as statistically significant.

Results

A total of 224 children (112 highly active antiretroviral therapy [HAART]-naïve and 112 HAART-experienced) participated in the study. The magnitude of anemia, thrombocytopenia, neutropenia, leukopenia and pancytopenia among HAART-naïve HIV-infected children were 30.4%, 9.8%, 8%, 4.5% and 1.8%, respectively. The overall prevalence of anemia, neutropenia, thrombocytopenia, leukopenia and pancytopenia were 29.5%, 8.9%, 8%, 4.5% and 1.4%, respectively. Cluster of differentiation-4 percentage and mean corpuscular volume were significantly different between HAART-experienced and HAART-naïve children. Being of younger age and severely immunosuppressed were risk factors of anemia.

Conclusion

Anemia was the most common cytopenia, followed by neutropenia. Severe immunosuppression and younger age were significantly associated with anemia. Therefore, emphasis should be given for investigation and management of cytopenias in HIV-infected children, particularly for those who are immunosuppressed and of younger age.

A Growth and Nutritional Study of HIV Seropositive Children from West Bengal under Direct Care of Medical Caregivers

AIM

To evaluate the nutritional status of HIV seropositive children, aged 2-10 years with age - matched controls and examine the role of nutritional intervention and HRT on their growth indices.

MATERIALS AND METHODS

It was a cross-sectional study done at a HIV Clinic of a teaching hospital. Fifty six seropositive children (age 2-10 year) classified as cases, and 60 seronegative age - matched controls were taken. Demographic and anthropometric characteristics were collected via valid instruments. HIV grading and adherence to HRT were assessed by using validated questionnaires.

RESULTS

Of the cases majority (87.5%) were infected by vertical transmission from mother to child, the remaining were infected by blood transfusion out of which 1.78% were haemophiliacs and remaining were thalassaemics. The prevalence of underweight among cases was 64.3%, compared to prevalence of 61% among controls. The prevalence of stunting was 44.6% among cases, while the prevalence of severe stunting was 14.3%. The prevalence of wasting among cases was 30.35%, while 7% cases were severely wasted. Only 23.33% controls were wasted. There was a significant difference in the Height- for-age between cases and controls, in the age of 4 years, 5 years and 6 years (p-value <0.05).

CONCLUSION

There was a significant difference in the Height- for-age between cases and controls, in the age of 4 years, 5 years and 6 years, indicating the need for proper nutritional intervention and timely HIV antiretroviral therapy to prevent stunting.

HIV-infected children in the Asia-Pacific region with baseline severe anemia: antiretroviral therapy and outcomes

BACKGROUND

Severe anemia is common among children infected with human immunodeficiency virus (HIV). The choice of antiretroviral (ART) regimen needs careful consideration. No information is available regarding the initial ART regimens used in the Asia-Pacific region and the rate of switch of ART regimens in HIV-infected children with severe anemia.

OBJECTIVES

To study the initial ART regimens and the rate of switch of ART regimens used during the first 36 months in HIV-infected children with severe anemia and to evaluate their clinical and laboratory outcomes.

METHODS

We analyzed regional cohort data of 130 Asian children aged <18 years with baseline severe anemia (hemoglobin <7.5 g/dl) who started antiretroviral therapy (ART) between January 2003 and September 2013.

RESULTS

At ART initiation, median age was 3.5 years old (interquartile range (IQR) 1.7 to 6.3) and median hemoglobin was 6.7 g/dL (IQR 5.9-7.1, range 3.0-7.4). Initial ART regimens included stavudine (85.4%), zidovudine (13.8%), and abacavir (0.8%). In 81 children with available hemoglobin data after 6 months of ART, 90% recovered from severe anemia with a median hemoglobin of 10.7 g/dL (IQR 9.6-11.7, range 4.4-13.5). Those starting AZT-based ART had a mortality rate of 10.8 (95% confidence interval (CI) 4.8-23.9) per 100 patient-years compared to 2.7 (95% CI 1.6-4.6) per 100 patient-years among those who started d4T-based ART.

CONCLUSIONS

With the phase-out of stavudine, age-appropriate non-zidovudine options are needed for younger Asian children with severe anemia.

An Evaluation of Alternative Markers to Guide Initiation of Anti-retroviral Therapy in HIV-Infected Children in Settings where CD4 Assays are not Available

OBJECTIVES

In settings where CD4 testing is not available, alternative markers to start paediatric anti-retroviral therapy (ART) could be used. A comprehensive evaluation of these markers has not been performed.

METHODS

Prospective cross-sectional study of HIV-infected Malawian children not eligible for ART based on clinical criteria. Associations between CD4 and alternative markers [haemoglobin, total lymphocyte count (TLC), serum albumin, thrombocytes and growth parameters] were analysed, and accuracy of existing and new cut-offs were evaluated.

RESULTS

In all, 417 children were enrolled. Of 261 children aged ≥5 years, 155 (59%) qualified to start ART using CD4. In this group, only TLC was associated with CD4 (p < 0.001). Sensitivity for TLC was 21% (95% CI: 15-29%), using World Health Organization cut-offs. Improved cut-offs increased sensitivity to 73% (95% CI: 65-80%), specificity 62% (95% CI: 52-72%).

CONCLUSION

Clinical staging alone is an unreliable strategy to start ART in children. TLC is the only alternative marker for CD4, cut-offs need to be revised though.

Health & nutritional status of HIV infected children in Hyderabad, India

BACKGROUND & OBJECTIVES

Information on nutritional status of HIV infected children from India is lacking and is required before taking up nutritional supplementation trials. Thus, the aim of the present study was to assess the growth and morbidity status of HIV infected children over a period of one year in a city in southern India.

METHODS

This was an observational study carried out between July 2009 and February 2011, at two orphanages in Hyderabad, India. Seventy seven HIV-positive children aged between 1 and half and 15 years, both on and not on antiretroviral therapy (ART) were included. Nutritional status was assessed longitudinally for one year by weight gain, linear growth and body composition. Serum samples were analyzed for haemoglobin, micronutrients, CD4 and CD8 counts. Dietary intakes were assessed by institutional diet survey and morbidity data were recorded every day for 12 months.

RESULTS

Mean energy intakes were less than recommended dietary allowance (RDA) in all age groups. Iron and folate intakes were less than 50 per cent of RDA; 46 (59.7%) children were stunted, 36 (46.8%) were underweight and 15 (19.5%) had low BMI for age. Anaemia was observed in 35 (45.5%) children. Micronutrient deficiencies such as vitamin D (40/77; 51.9%), vitamin A (11/77; 14.3%), folate (37/77; 48.1%), iron (38/77; 49.3%) were widely prevalent. HIV viral load was higher in children not on ART and those with morbidity. Respiratory (36.6%) and dermatological illnesses (18.8%) were the commonest presentations.

INTERPRETATION & CONCLUSIONS

Acute, chronic malnutrition and micronutrient deficiencies were common in HIV infected children, especially in those not on ART and having morbidity. With severe malnutrition being an alarming consequence of HIV, prophylactic nutritive care should be considered for integration into HIV care strategies besides initiation of ART to improve the nutritional status and quality of life of these children.

Anemia, diet and therapeutic iron among children living with HIV: a prospective cohort study

BACKGROUND

Children living with HIV have higher-than-normal prevalence of anemia. The beneficial effect of therapeutic iron has been questioned in the setting of high prevalence of infections. This study examines anemia prevalence and effect of standard therapeutic iron on HIV disease progression among children.

METHODS

Perinatally-infected children aged 2-12 years were enrolled at three sites in southern India, and were followed for 1 year with clinical assessments, dietary recall and anthropometry. Laboratory parameters included iron markers (ferritin, soluble transferrin receptor) and other micronutrient levels (vitamin A, B12, folate). Iron was given to anemic children based on WHO guidelines. Statistical analyses including frequency distributions, chi square tests and multivariate logistic regression were performed using Stata v13.0.

RESULTS

Among 240 children enrolled (mean age 7.7 years, 54.6% males), median CD4 was 25%, 19.2% had advanced disease, 45.5% had malnutrition, and 43.3% were on antiretroviral treatment (ART) at baseline. Anemia was prevalent in 47.1% (113/240) children. Iron deficiency was present in 65.5%; vitamin A and vitamin B12 deficiency in 26.6% and 8.0% respectively; and anemia of inflammation in 58.4%. Independent risk factors for anemia were stunting, CD4 < 25%, detectable viral load ≥ 400 copies/ml and vitamin A deficiency. Inadequate dietary iron was prominent; 77.9% obtained less than two-thirds of recommended daily iron. Among clinically anemic children who took iron, overall adherence to iron therapy was good, and only minor self-limiting adverse events were reported. Median hemoglobin rose from 10.4 g/dl to 10.9 mg/dl among those who took iron for 3 months, and peaked at 11.3 mg/dl with iron taken for up to 6 months. Iron was also associated with a greater fall in clinical severity of HIV stage; however when adjusted for use of ART, was not associated with improvement in growth, inflammatory and CD4 parameters.

CONCLUSIONS

Children living with HIV in India have a high prevalence of anemia mediated by iron deficiency, vitamin A deficiency and chronic inflammation. The use of therapeutic iron for durations up to 6 months appears to be safe in this setting, and is associated with beneficial effects on anemia, iron deficiency and HIV disease progression.

Prevalence and associated risk factors of anemia among HIV infected children attending Gondar university hospital, Northwest Ethiopia: a cross sectional study

BACKGROUND

Anemia is the most common hematological abnormalities in HIV patients and it is a wide spread public health problem. The World Health Organization estimates that over 2 billion people are anemic worldwide with more than 100 million of these anemic children living in Africa. In Ethiopia, there is limited information about the prevalence and factors associated with anemia among HIV positive children. Thus, this study aimed to determine the prevalence and associated factors of anemia among HIV infected children aged 6 months to 14 years in Gondar university Hospital antiretroviral treatment clinic.

METHODS

A cross-sectional study was conducted on 265 HIV infected children from February to June 2013 on HIV infected children attending Gondar university Hospital ART clinic. The study subjects were selected with systematic random sampling technique. Data of socio demographic characteristics and clinical conditions of the study subjects was collected using a structured pretested questionnaire. Hemoglobin value and CD4 counts were determined by cell Dyne 1800 and FACS count machine respectively. WHO Cut off value of hemoglobin was taken and adjusted to altitude to define anemia. Data was analyzed by using the SPSS version 20 statistical software and bivariate and multivariate logistic regression was used to identify predictors.

RESULTS

Anemia was present in 16.2 % (43 /265) of children, 60.5 % of them had mild anemia, 37.2 % had moderate anemia and 2.3 % had severe anemia. About 46.5 % of anemic children had normocytic-normochromic anemia followed by macrocytic-normochromic anemia (39.5 %). In this study, anemia was associated with eating green leafy vegetables (OR = 0.43, 95 % CI (0.188-0.981) and being on cotrimoxazole treatment (OR = 2.169, 95 % CI (1.047-4.49). But there was no significant association with age, sex, WHO clinical stage, opportunistic infections, intestinal parasitic infection and CD4 count percentage.

CONCLUSIONS

The majority of HIV positive children in Northwest Ethiopia have a mild type of anemia and the increase in prevalence of anemia is due to being on cotrimoxazole and eating green leafy vegetables. Therefore, early diagnosis and treatment of anemia is essential in these patients.

Nutrition status of HIV+ children in Botswana

Purpose

– Identifying and addressing poor nutritional status in school-aged children is often not prioritized relative to HIV/AIDS treatment. The purpose of this paper is to elucidate the benefits of integrating nutrition (assessment and culturally acceptable food supplement intervention) in the treatment strategy for this target group.

Design/methodology/approach

– The authors conducted a randomized, double blind pre-/post-intervention trial with 201 HIV-positive children (six to 15 years) in Botswana. Eligibility included CD4 cell counts < 700/mm3 (a marker for the severity of HIV infection), documented treatment with antiretroviral (ARV) drugs, and no reported evidence of taking supplemental food products with one or more added nutrients in the six-month period prior to the study. The intervention (12 months) consisted of two food supplements for ethical reason, one with a higher protein content, bean (bean-sorghum based) group (n=97) and a cereal (sorghum) group (n=104) both of which contained added energy- and micro- nutrients. Anthropometric and biochemical nutritional status indicators (stunting, wasting, underweight, skinfolds for fat and muscle protein reserves, and hemoglobin levels) were compared within and between the bean and the cereal groups pre- and post-intervention separately for children six to nine years and ten to 15 years.

Findings

– Older children (ten to 15 years) fared worse overall compared to those who were younger (six to nine years) children in anthropometric and protein status indicators both at baseline and post-intervention. Among children six to nine years, the mid arm circumference and blood hemoglobin levels improved significantly in both the bean and cereal groups (p < 0.01 and p < 0.05, respectively). Although the BMI for age z-score and the triceps skinfold decreased significantly in the bean group, the post-intervention subscapular skinfold (fat stores) was significantly higher for the bean group compared to the cereal group (p < 0.05). Among children ten to 15 years, both the bean and the cereal groups also showed improvement in mid arm circumference (p < 0.001), but only those in the bean group showed improvement in hemoglobin (p < 0.01) post-intervention.

Originality/value

– Similar significant nutritional status findings and trends were found for both food interventions and age within group pre- vs post-comparisons, except hemoglobin in the older children. Post-intervention hemoglobin levels for the type food supplement was higher for the “bean” vs the “cereal” food in the younger age group. The fact that all children, but especially those who were older were in poor nutritional status supports the need for nutrition intervention in conjunction with ARV treatment in children with HIV/AIDS, perhaps using a scaled up future approach to enhance desired outcomes.

Prevalence of anemia and nutritional status among HIV-positive children receiving antiretroviral therapy in Harar, eastern Ethiopa

PURPOSE

Anemia and growth retardation are common manifestations of HIV-positive children, which threaten their lives. Therefore, this study tried to assess the burden of anemia and the nutritional status of HIV-positive children receiving antiretroviral therapy (ART) in eastern Ethiopa.

PATIENTS AND METHODS

A total of 108 records of children on ART followed up in Hiwot Fana Specialized University Hospital from 2007 to 2010 were retrospectively reviewed from November 1 to November 30, 2011.

RESULTS

Approximately 54.4% of the children had been anemic before the initiation of their ART (at baseline): 7.8% were severely anemic and 44.7% were moderately anemic. These percentages were higher in preschool children than in school children (adjusted odds ratio [AOR]: 4.80 [95% confidence interval {CI}: 1.96, 11.75]), and were higher in males than in females (AOR: 2.61 [95% CI: 1.06, 6.45]). The prevalence of anemia was reduced to 39.2% 1 year after initiation of ART. The increasing of hemoglobin values was highly significant for both zidovudine (AZT)- and stavudine (d4T)-based ART (P<0.05). At baseline, 51.6% of the study subjects were underweight (weight-for-age Z score less than -2 standard deviation [SD]); 49.1% were stunted (height-for-age Z score less than -2 SD); and 31.5% were wasted (body mass index less than -2 SD), which, after a year on ART, declined to 8.9%, 15.9%, and 9.8%, respectively.

CONCLUSION

There was high prevalence of anemia and growth failure among HIV-infected children in the study area. However, there was a decline after initiation of ART. Therefore, adherence counseling to strengthen the uptake of ART is recommended. Moreover, large-scale, prospective studies should be done to understand the magnitude and etiology of the problems with HIV-negative control groups.

Factors Associated with Anemia among Children Aged 6-23 Months Attending Growth Monitoring at Tsitsika Health Center, Wag-Himra Zone, Northeast Ethiopia

Background. Globally, about 47.4% of children under five are suffering from anemia. In Ethiopia, 60.9% of children under two years are suffering from anemia. Anemia during infancy and young childhood period is associated with poor health and impaired cognitive development, leading to reduced academic achievement and earnings potential in their adulthood life. However, there is scarcity of information showing the magnitude of iron deficiency anemia among young children in Ethiopia. Therefore, this study aimed at assessing prevalence and associated factors of iron deficiency anemia among children under two (6-23 months). Methods. Institution based cross-sectional study was carried out from March to May, 2014, at Tsitsika Health Center in Wag-Himra Zone, Northeast Ethiopia. Systematic random sampling technique was employed. Automated hemoglobin machine was used to determine the hemoglobin level. Socioeconomic and demographic data were collected by using a pretested and structured questionnaire. Binary logistic regression analysis was used to identify associated factors and odds ratio with 95% CI was computed to assess the strength of association. Results. Total of 347 children participated in this study. The overall prevalence of anemia was 66.6%. In multivariate logistic regression analysis, male sex (AOR = 3.1 (95% CI: 1.60-5.81)), 9-11 months of age (AOR = 9.6 (95% CI: 3.61-25.47)), poor dietary diversity (AOR = 3.2 (95% CI: 1.35-7.38)), stunting (AOR = 2.7 (95% CI: 1.20-6.05)), diarrhea (AOR = 4.9 (1.63-14.59)), no formal education (AOR = 2.6 (95% CI: 1.26-5.27)), early initiation of complementary food (AOR = 11.1 (95% CI: 4.08-30.31)), and lowest wealth quintile (AOR = 3.0 (95% CI: 1.01-8.88)) were significantly associated with anemia. Conclusion. The overall prevalence of anemia among children who aged 6-23 months has sever public health importance in the study area. Integrated efforts need to be prioritized to improve health as well as appropriate infant and young child feeding practice among children under.

Prevalence and risk factors of undernutrition among antiretroviral-therapy-naïve subjects aged under 5 years old in Makurdi, Nigeria: a retrospective study

Background

Undernutrition is common in human immunodeficiency virus (HIV) infection and it contributes significantly to its morbidity and mortality. However, as far as we are aware, few studies have described the risk factors of undernutrition among HIV-infected Nigerian children. The study reported here aimed to determine the prevalence and risk factors of undernutrition among HIV-infected, antiretroviral therapy (ART)-naïve children aged under 5 years old in Makurdi, Nigeria.

Methods

A retrospective, cross-sectional study was undertaken at the Federal Medical Centre, Makurdi, between June 2010 and June 2011. Logistic regression modelling was used to determine the risk factors of undernutrition.

Results

Data on 182 HIV-infected children (88 males and 94 females), aged between 6 weeks and 59 months were studied. The prevalence of undernutrition was 12.1%, 33.5%, and 54.4% for underweight, wasting, and stunting, respectively. In multivariate regression analyses, being female (adjusted odds ratio [AOR] 0.292, 95% [confidence interval] CI 0.104–0.820, P=0.019), the child’s caregiver being on ART (AOR 0.190, 95% CI 0.039–0.925, P=0.04), and the absence of tuberculosis in the child (AOR 0.034, 95% CI 0.003–0.357, P=0.005) were independently protective against underweight. Subjects who were exclusively breastfed in the first 6 months of life were protected from stunting (AOR 0.136, 95% CI 0.032–0.585, P=0.007). No factor impacted significantly on wasting in multivariate analyses.

Conclusion

Undernutrition among HIV-infected, ART-naïve children aged under 5 years old may be reduced if programmatic interventions are guided toward early initiation of ART among eligible HIV-infected caregivers and the promotion of HIV/tuberculosis coinfection control efforts. Also, the importance of exclusive breastfeeding in reducing undernutrition cannot be overemphasized.

Undernutrition and anaemia among HAART-naïve HIV infected children in Ile-Ife, Nigeria: a case-controlled, hospital based study

INTRODUCTION

Case control studies that assess the burden and factors associated with undernutrition and anaemia among HAART naïve HIV infected children in Nigeria is very sparse. This will help to formulate nutritional programs among these children.

METHODS

Seventy HAART naive HIV infected children aged 18 months and above were as well as seventy age and sex matched HIV negative children were recruited from August 2007 to January 2009 at Paediatric Clinic of Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Their bio data, WHO clinical stage, anthropometric measurements, haematocrit, serum albumin and CD4 counts were taken with other parameters according to a study proforma.

RESULTS

The prevalence of stunting, underweight and wasting among the HIV infected subjects were 48. 6%,58. 6% and 31. 4% respectively which as significantly higher than 28. 1%, 7. 1% and 28. 1% among the HIV negative controls. 20. 1% of the HIV infected children were marasmic compared to 2. 3% of the controls. Triple anthropometric failure was found in 7. 1% of the subjects as compared to none among the controls. Anaemia is significantly more prevalent among the subjects than the controls (70. 0% vs 31. 4%; p<0. 001). The prevalence of anaemia was higher in the HIV infected subjects with undernutrition. Low socioeconomic status, hypoalbuminemia and severe immunosuppression are significantly associated with higher undernutrition prevalence.

CONCLUSION

Several years after availability of HAART, undernutrition and anaemia remain widely prevalent among newly presenting HAART naïve HIV infected Nigerian children. Nutritional supplementation and evaluation for anaemia still need close attention in the management of these children.

Quality of life and psychosocial well-being among children living with HIV at a care home in Southern India

This study was designed to evaluate the quality of life (QOL) of children living with HIV at an institutional care home in Bangalore, India. The Sneha Care Home is a unique residence that provides educational and community support with a focus on physical, nutritional, medical, and psychological care for orphans and vulnerable children. Cross-sectional health measures and interview data were collected from 97 residents including 52 boys and 45 girls between 5 and 12 years of age (mean age = 9). QOL was measured with the Pediatric Quality of Life 4.0 (PedsQL) Inventory. Caregivers perceived children to have an overall higher QOL than was self-reported by children (total score 83 vs. 78). Our findings indicated self-reported QOL decreased with age of the child, while caregiver-reported QOL increased with age, suggesting a need to ensure greater psychological support for older children. Physical measures showed the children's clinical severity of disease remained well controlled living in this residential, values-based care home.

Anaemia and zidovudine-containing antiretroviral therapy in paediatric antiretroviral programmes in the IeDEA Paediatric West African Database to evaluate AIDS

INTRODUCTION

There is a risk of anaemia among HIV-infected children on antiretroviral therapy (ART) containing zidovudine (ZDV) recommended in first-line regimens in the WHO guidelines. We estimated the risk of severe anaemia after initiation of a ZDV-containing regimen in HIV-infected children included in the IeDEA West African database.

METHODS

Standardized collection of data from HIV-infected children (positive PCR<18 months or positive serology ≥ 18 months) followed up in HIV programmes was included in the regional IeDEA West Africa collaboration. Ten clinical centres from seven countries contributed (Benin, Burkina Faso, Côte d'Ivoire, Gambia, Ghana, Mali and Senegal) to this collection. Inclusion criteria were age <16 years and starting ART. We explored the data quality of haemoglobin documentation over time and the incidence and predictors of severe anaemia (Hb<7 g/dL) per 100 child-years of follow-up over the duration of first-line antiretroviral therapy.

RESULTS

As of December 2009, among the 2933 children included in the collaboration, 45% were girls, median age was five years; median CD4 cell percentage was 13%; median weight-for-age z-score was-2.7; and 1772 (60.4%) had a first-line ZDV-containing regimen. At baseline, 70% of the children with a first-line ZDV-containing regimen had a haemoglobin measure available versus 76% in those not on ZDV (p ≤ 0.01): the prevalence of severe anaemia was 3.0% (n=38) in the ZDV group versus 10.2% (n=89) in those without (p<0. 01). Over the first-line follow-up, 58.9% of the children had ≥ 1 measure of haemoglobin available in those exposed to ZDV versus 60.4% of those not (p=0.45). Severe anaemia occurred in 92 children with an incidence of 2.47 per 100 child-years of follow-up in those on a ZDV-containing regimen versus 4.25 in those not (p ≤ 0.01). Adjusted for age at ART initiation and first-line regimen, a weight-for-age z-score ≤-3 was a strong predictor associated with a 5.59 times risk of severe anaemia (p<0.01).

CONCLUSIONS

Severe anaemia is frequent at baseline and guides the first-line ART prescription, but its incidence seems rare among children on ART. Severe malnutrition at baseline is a strong predictor for development of severe anaemia, and interventions to address this should form an integral component of clinical care.

Incidence and predictors of severe anemia in Asian HIV-infected children using first-line antiretroviral therapy

BACKGROUND

There are limited data on treatment-related anemia in Asian HIV-infected children.

METHODS

Data from Asian HIV-infected children aged <18 years on first-line highly active antiretroviral therapy (HAART) were used. Children who had pre-existing severe anemia at baseline were excluded. Anemia was graded using the United States Division of AIDS (DAIDS) 2004 table. Potential risk factors for severe anemia were assessed by logistic regression.

RESULTS

Data from 1648 children (51.9% female, 62.8% World Health Organization (WHO) stage 3/4) were analyzed. Median (interquartile range) age was 6.8 (3.7-9.6) years, CD4% was 9 (3-16)%, and plasma HIV-RNA was 5.2 (4.7-5.6) log10 copies/ml at HAART initiation in those with available testing. The most common regimens were stavudine/lamivudine/nevirapine (42%) and zidovudine/lamivudine/nevirapine (25%). Severe anemia was identified in 47 (2.9%) children after a median time of 6 months after HAART initiation, with an incidence rate of 5.4 per 100 child-years. Mild anemia or moderate anemia at baseline (p = 0.024 and p = 0.005, respectively), previous or current use of zidovudine (p < 0.0001 and p = 0.013, respectively), and male sex (p = 0.008) were associated with severe anemia. Higher weight-for-age z-score (p = 0.004) was protective.

CONCLUSIONS

The incidence of severe anemia in Asian HIV-infected children after HAART initiation was low and mainly occurred during the first few months after HAART initiation. Mild to moderate anemia at baseline and using zidovudine were independent risk factors for the development of severe anemia.

Defining pediatric malnutrition: a paradigm shift toward etiology-related definitions

Lack of a uniform definition is responsible for underrecognition of the prevalence of malnutrition and its impact on outcomes in children. A pediatric malnutrition definitions workgroup reviewed existing pediatric age group English-language literature from 1955 to 2011, for relevant references related to 5 domains of the definition of malnutrition that were a priori identified: anthropometric parameters, growth, chronicity of malnutrition, etiology and pathogenesis, and developmental/ functional outcomes. Based on available evidence and an iterative process to arrive at multidisciplinary consensus in the group, these domains were included in the overall construct of a new definition. Pediatric malnutrition (undernutrition) is defined as an imbalance between nutrient requirements and intake that results in cumulative deficits of energy, protein, or micronutrients that may negatively affect growth, development, and other relevant outcomes. A summary of the literature is presented and a new classification scheme is proposed that incorporates chronicity, etiology, mechanisms of nutrient imbalance, severity of malnutrition, and its impact on outcomes. Based on its etiology, malnutrition is either illness related (secondary to 1 or more diseases/injury) or non-illness related, (caused by environmental/behavioral factors), or both. Future research must focus on the relationship between inflammation and illness-related malnutrition. We anticipate that the definition of malnutrition will continue to evolve with improved understanding of the processes that lead to and complicate the treatment of this condition. A uniform definition should permit future research to focus on the impact of pediatric malnutrition on functional outcomes and help solidify the scientific basis for evidence-based nutrition practices.

Pathogenesis and clinical implications of HIV-related anemia in 2013

Anemia is a common feature of HIV-related disease and has been uniformly demonstrated to be an independent predictor of morbidity and mortality. Although anemia often responds to combination antiretroviral therapy, many patients remain anemic despite therapy and such persistent anemia continues to negatively affect prognosis regardless of drug response. Anemia is also a common feature of normal aging. We postulate that the pathophysiology of anemia in HIV, especially that which persists in the face of combination antiretroviral therapy, is a reflection of underlying proinflammatory pathways that are also thought to contribute to anemia in the elderly, as well as other age-related chronic diseases such as cardiovascular disease and chronic obstructive pulmonary disease. This suggests that HIV induces inflammatory pathways that are associated with a pattern of accelerated aging and that anemia is a biomarker of these processes. A better understanding of the pathophysiology of HIV-related anemia may provide important entry points for improving the chronic manifestations of HIV-related disease.

Prevalence of anemia and underlying iron status in naive antiretroviral therapy HIV-infected children with moderate immune suppression

Anemia is common in HIV-infected children and iron deficiency is thought to be a common cause. This study investigates the prevalence of anemia, thalassemia, and underlying iron status in Thai and Cambodian children without advanced HIV disease to determine the necessity of routine iron supplementation. Antiretroviral (ARV)-naive HIV-infected Asian children aged 1-12 years, with CD4 15-24%, CDC A or B, and hemoglobin (Hb) ≥7.5 g/dl were eligible for the study. Iron studies, serum ferritin, Hb typing, and C-reactive protein were assessed. Anemia was defined as Hb <11.0 g/dl in children <5 years of age or <11.5 g/dl in children 5-12 years. We enrolled 299 children; 57.9% were female and the mean (SD) age was 6.3 (2.9) years. The mean (SD) CD4% and HIV-RNA were 20% (4.6) and 4.6 (0.6) log(10) copies/ml, respectively. The mean (SD) Hb and serum ferritin were 11.2 (1.1) g/dl and 78.3 (76.4) μg/liter, respectively. The overall iron deficiency anemia (IDA) prevalence was 2.7%. One hundred and forty-eight (50%) children had anemia, mostly of a mild degree. Of these, 69 (46.6%) had the thalassemia trait, 62 (41.8%) had anemia of chronic disease (ACD), 9 (6.1%) had thalassemia diseases, 3 (2.0%) had iron deficiency anemia, and 5 (3.4%) had IDA and the thalassemia trait. The thalassemia trait was not associated with increased serum ferritin levels. Mild anemia is common in ARV-naïve Thai and Cambodian children without advanced HIV. However, IDA prevalence is low; with the majority of cases caused by ACD. A routine prescription of iron supplement in anemic HIV-infected children without laboratory confirmation of IDA should be discouraged, especially in regions with a high prevalence of thalassemia and low prevalence of IDA.

Pharmacotherapy of pediatric HIV infection

The delivery of safe and effective antiretroviral therapy to children and adolescents is crucial to save the lives of millions of children worldwide. The immunologic response to human immunodeficiency infection is closely related to a child's development and creates age-specific parameters for the evaluation of therapeutic response to antiretroviral therapy. Similarly, the development and maturation of organ systems involved in drug absorption, distribution, metabolism, and elimination determines significant changes in the pharmacokinetics of antiretroviral drugs throughout childhood. The authors review the evolution in treatment of pediatric HIV from infancy through adolescence.

Growth patterns and anaemia status of HIV-infected children living in an institutional facility in India

OBJECTIVE

To understand the health status of HIV orphans in a well-structured institutional facility in India.

METHOD

Prospective longitudinal analysis of growth and anaemia prevalence among these children, between June 2008 and May 2011.

RESULTS

A total of 85 HIV-infected orphan children residing at Sneha Care Home, Bangalore, for at least 1 year, were included in the analysis. Prevalence of anaemia at entry into the home was 40%, with the cumulative incidence of anaemia during the study period being 85%. At baseline, 79% were underweight and 72% were stunted. All children, irrespective of their antiretroviral therapy (ART) status, showed an improvement in nutritional status over time as demonstrated by a significant increase in weight (median weight-for-age Z-score: -2.75 to -1.74, P < 0.001) and height Z-scores (median height-for-age Z-score: -2.69 to -1.63, P < 0.001).

CONCLUSION

These findings suggest that good nutrition even in the absence of ART can bring about improvement in growth. The Sneha Care Home model indicates that the holistic approach used in the Home may have been helpful in combating HIV and poor nutritional status in severely malnourished orphaned children.

Clinico-immunological profile and outcome of antiretroviral therapy in HIV-positive children

OBJECTIVES

To study the clinico-immunological, nutritional and growth characteristics of HIV-infected children and the impact of antiretroviral therapy (ART) on these parameters.

DESIGN

Retrospective study.

SETTING

Out-patient department of a paediatric ART centre, Delhi, India.

SUBJECTS

HIV-positive children registered at the paediatric ART centre of the hospital were enrolled (n 130). Anthropometric measurements were used to classify children into the type of malnutrition according to definitions of the WHO and US Centers for Disease Control and Prevention. Clinical and immunological status of the children was recorded as per WHO guidelines. First-line ART was started based on guidelines of the National AIDS Control Organization. Nutritional status and clinico-immunological characteristics were followed up annually in children receiving ART.

RESULTS

Of children ≤5 years of age (n 54), stunting was noted in 42·5 % contrary to wasting seen in only 12·9 %. In children >5 years of age (n 76), short stature (40·7 %) and underweight (39·4 %) were seen in almost equal proportions. Asymptomatic presentation was noted in 60·0 %. Following ART, a reduction in wasting was noted in 75·0 % of children ≤5 years of age, whereas only 44·4 % of underweight children >5 years of age showed an improvement after therapy. Stunting and short stature continued to persist in all in children (≤5 years and >5 years, respectively). Clinico-immunologically, 67·5 % improved in clinical status and 62·5 % showed immunological improvement.

CONCLUSIONS

ART improves the acute parameters of nutritional status like wasting. It also improves the clinical outcome and restores the immune system. At present first-line ART is effective in HIV-positive children.

The prevalence and etiology of anemia among HIV-infected children in India

In this report, the prevalence and multifactorial etiology of anemia among Indian human immunodeficiency virus (HIV)-infected children are described. HIV-infected children aged 2-12 years were prospectively enrolled in 2007-2008. Measured parameters included serum ferritin, vitamin B(12), red-cell folate, soluble transferrin receptor, and C-reactive protein. Children received antiretroviral therapy (ART), iron and, folate supplements as per standard of care. Among 80 enrolled HIV-infected children (mean age 6.8 years), the prevalence of anemia was 52.5%. Etiology of anemia was found to be iron deficiency alone in 38.1%, anemia of inflammation alone in 38.1%, combined iron deficiency and anemia of inflammation alone in 7.1%, vitamin B(12) deficiency in 7.1%, and others in 9.5%. Median iron intake was 5.7 mg/day (recommended dietary allowance 18-26 mg/day). Compared to nonanemic children, anemic children were more likely to be underweight (weight Z-score -2.5 vs. -1.9), stunted (height Z-score -2.6 vs. -1.9), with lower CD4 counts (18% vs. 24%, p < 0.01), and higher log viral load (11.1 vs. 7.1, p < 0.01). Hemoglobin (Hb) improved significantly among those who started ART (baseline Hb 11.6 g/dl, 6-month Hb 12.2 g/dl, p = 0.03). Children taking ART combined with iron supplements experienced a larger increase in Hb compared to those receiving neither ART nor iron supplements (mean Hb change 1.5 g/dl, p < 0.01).

CONCLUSION

Anemia, particularly iron deficiency anemia and anemia of inflammation, is highly prevalent among children with HIV infection. Micronutrient supplements combined with ART improved anemia in HIV-infected children.

The frequency and magnitude of growth failure in a group of HIV-infected children in Cameroon

BACKGROUND

Growth impairment is a major manifestation of HIV infection in children and has been implicated as a major contributor to both morbidity and mortality. This study the first to be done in this setting, was aimed at comparing the growth of HIV infected children to that of non-infected children in two referral health facilities in Yaoundé, Cameroon.

METHODS

A prospective case control study was carried out on 39 HIV infected children in two referral hospitals and followed up for a period of 12 months. Anthropometric measurements were taken and the sociodemographic variables of mothers and infants noted. Thirty nine infected children (mean age 45.3 months ± 41.6 SD) were age and sex matched with 39 non-infected children (mean age 44.4 ± 40.7 months).

RESULTS

Out of the 39 infected children, 26 (66.7%) had at least one of the three anthropometric indices (weight for height, weight for age, height for age) Z scores less than -2. Throughout follow-up, 20.5% of the infected children were wasted (weight to height Z score < -2) versus none in the control group, 56.4% underweight (weight for age Z score < -2) in the infected versus 2.6% in the control group, and 51.3% stunted (height for age Z score < -2) in contrast to 5.1% in the control group.

CONCLUSION

This study demonstrated that wasting; underweight and stunting are common findings in HIV- infected children, thus stressing the importance of anthropometry in the routine care of these children.

Abnormalities in body composition and nutritional status in HIV-infected children and adolescents on antiretroviral therapy

This cross-sectional study aimed to compare growth, nutritional status and body composition outcomes between a group of 94 HIV-infected children and adolescents on antiretroviral therapy (ART) and 364 healthy controls, and to evaluate their association with clinical and lifestyle variables within the HIV-infected group. When compared with the control group, HIV patients had higher risk of stunting (odds ratio [OR] 5.33, 95% confidence interval [CI]: 2.83-10.04) and thinness (OR 4.7, 95% CI: 2.44-9.06), higher waist-to-hip ratios (medians 0.89 versus 0.82 for boys and 0.90 versus 0.77 for girls, P < 0.001), and lower prevalence of overweight or obesity (OR 0.33, 95% CI: 0.14-0.78). Protease inhibitor usage was associated with thinness (OR 3.51, 95% CI 1.07-11.44) and lipoatrophy (OR 3.5, 95% CI 1.37-8.95). HIV-infected children on ART showed significant nutritional status and body composition abnormalities, consistent with the severity of vertical HIV infection and the consequences of prolonged ART.

Treatment for anemia in people with AIDS

BACKGROUND

Anemia is common in persons with HIV infection and is associated with poor prognosis. There is a need to assess the effects of anemia treatments, and to determine whether these interventions are beneficial.

OBJECTIVES

To determine the efficacy and safety of treatments for anemia in people with HIV infection and AIDS.

SEARCH STRATEGY

The Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 10, 2010), MEDLINE (1980-November 25, 2010), EMBASE (1980-November 25, 2010), LlLACS (1982 to November 25, 2010), Africa Index Medicus (up to November 9, 2010), ISI Web of Knowledge (2005 to October 9, 2010), Scirus (October 9, 2010) reference lists of relevant articles. We asked the Cochrane HIV/AIDS and Pregnancy and Childbirth Groups to check their Specialised Registers. We also checked the reference lists of all trials identified by the above methods.

SELECTION CRITERIA

Randomized trials assessing the effects of treatments for anemia in people diagnosed with HIV infection. There were no age restrictions.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed relevant studies for inclusion. Data extraction and quality assessment of relevant studies was performed by two authors and checked by the other two authors.

MAIN RESULTS

Six trials with a high risk of bias, including 537 patients, met the inclusion criteria. These trials only covered recombinant Human erythropoietin alfa (rHuEPO). Two of them including adult and paediatric participants (84 participants and 4 events) comparing rHuEPO to placebo did not reduce the risk of mortality with a follow up to 12 weeks (pooled RR 0.56, 95% confidence interval (CI) 0.08 to 4.05, I(2) = 0%). Any trials that compared rHuEPO to placebo did not show any benefit on hematological values response, number of patients transfused, or number of packed red cell transfused. Two trial compared the effects of two rHuEPO dosing regimens on hemoglobin value and quality of life, but the effects are unclear. Three RCT reported high risk of attrition bias; therefore, were not included in a meta-analysis.

AUTHORS' CONCLUSIONS

This updated Cochrane review provides evidence that rHuEPO compared with placebo does not reduce mortality, does not reduce transfusion requirements, did not increase hemoglobin levels, and did not improve quality of life in HIV-infected patients with anemia. The results are based on six RCTs with high risk of bias. Therefore prescription of this intervention for treating anemia in patients with AIDS is not justified, unless new evidence from a large high quality trial alters this conclusion.

Addressing Tuberculosis in the Context of Malnutrition and HIV Coinfection

Background

Tuberculosis is the second leading cause of infectious disease mortality (1.8 million/year), after HIV/AIDS. There are more than 9 million new cases each year. One-third of the world's population, and 50% of adults in sub-Saharan Africa, South Asia, and South-East Asia, are infected, representing an enormous pool of individuals at risk for developing the disease. The situation is complicated by the HIV/AIDS pandemic, widespread undernutrition, smoking, diabetes, increased mobility, and emergence of multi- and extensively drug-resistant tuberculosis.

Objective

To review the scientific evidence about the interactions among tuberculosis, nutrition, and HIV coinfection.

Results

HIV infection and malnutrition lower immunity, increasing the risk of reactivation tuberculosis and primary progressive disease. Having either tuberculosis or HIV infection causes weight loss. Malnutrition markedly increases mortality among both tuberculosis and HIV/AIDS patients and should be treated concurrently with treatment of the infections. Tuberculosis treatment is a prerequisite for nutritional recovery, in addition to intake of nutrients required for rebuilding tissues, which is constrained in food-insecure households. Additional pharmaceutical treatment to reduce the catabolic impact of inflammation or promote growth may be needed. Specific nutrients can contribute to faster sputum smear clearance, which is important for reducing transmission, as well as faster weight gain when combined with an adequate diet. Adequate nutrition and weight gain in undernourished populations might reduce the incidence of tuberculosis.

Conclusions

The many risk factors for the development of tuberculosis need to be addressed simultaneously, especially HIV/AIDS and food insecurity and undernutrition. For stronger evidence-based guidelines, existing recommendations and clinical applications need to be more widely applied and evaluated.
