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

Dietary Iron Intake and HIV-Related Outcomes Among Adults Initiating Antiretroviral Therapy in Tanzania

OBJECTIVE

Anemia is highly prevalent among people living with HIV (PLWHIV) and is often due to iron deficiency. This study evaluated the relationship of dietary iron intake levels and sources with mortality and clinical outcomes among adults initiating HAART.

DESIGN

We conducted a secondary analysis of a multivitamin supplementation trial among 2293 PLWHIV initiating HAART in Dar es Salaam, Tanzania.

METHODS

Dietary iron intake was assessed with a food frequency questionnaire at HAART initiation, and participants followed until death or censoring. Total, animal-, and plant-sourced iron were categorized into quartiles. Intake of food groups was categorized into 0-1, 2-3, and ≥4 servings/wk. Cox proportional hazards models estimated hazard ratios for mortality and incident clinical outcomes.

RESULTS

There were 175 deaths (8%). Red meat intake was associated with a lower risk of all-cause mortality (HR: 0.54; 95% CI: 0.35 to 0.83), AIDS-related mortality (HR: 0.49; 95% CI: 0.28 to 0.85), and severe anemia (HR: 0.57; 95% CI: 0.35 to 0.91), when intake ≥4 servings/wk, compared with 0-1 servings/wk. Legume intake was a lower risk of associated with all-cause mortality (HR: 0.49; 95% CI: 0.31 to 0.77) and AIDS-related mortality (HR: 0.37; 95% CI: 0.23 to 0.61), when intake ≥4 servings/wk, compared with 0-1 servings/wk. Although total dietary iron and overall plant-sourced iron intake were not associated with the risk of mortality or HIV-related outcomes, the highest quartile of animal-sourced iron intake was associated with a lower risk of all-cause mortality (HR: 0.56; 95% CI: 0.35 to 0.90) and a lower risk of AIDS-related mortality (HR: 0.50; 95% CI: 0.30 to 0.90), compared with the lowest quartile.

CONCLUSION

Intake of iron-rich food groups may be associated with a lower risk of mortality and critical HIV-related outcomes among adults initiating HAART.

TRIAL REGISTRATION

The parent trial was registered at Clinicaltrials.gov . Identifier: NCT00383669.

Determinates of anemia among Human Immune Deficiency Virus positive children on Anti-retro Viral Therapy in selected health facilities, Northwest Ethiopia: A Case-Control Study

Even though antiretroviral therapy (ART) access for human immunodeficiency virus (HIV)-infected children increased dramatically, anaemia has continued as a challenge regardless of a cluster of differentiation (CD4) count and viral load. Hence, the present study aimed to assess the determinants of iron deficiency anaemia among children living with HIV after the initiation of ART. An institution-based unmatched case-control study was conducted among consecutively selected 712 children on HIV care from 1 September to 30 October 2022 in the Metekel zone. A pre-tested and structured data extraction checklist was used to collect the data. Data were analysed using STATA version 16 software. Binary logistic regression was used to find the association between independent variables and anaemia. The level of statistical significance was declared at a value of P < 0⋅05. A total of 712 HIV-positive children (178 cases and 534 controls) were included in this study, with a completeness rate of 98⋅8 %. In multivariable analysis, variables that have a statistically significant association with anaemia were as follows: CD4 count <350 (Adjusted Odds Ratio [AOR] 2⋅76; 95 % CI 1⋅76, 4⋅34), World Health Organization (WHO) clinical stage III (AOR 7⋅9; 95 % CI 3⋅5, 17⋅91) and stage IV (AOR 7⋅8; 95 % CI 3⋅37, 18⋅1), cotrimoxazole prophylaxis therapy (AOR 0⋅5; 95 % CI 0⋅31, 0⋅8) and mid-upper arm circumference (MUAC) ≤11⋅5 mm (AOR 2⋅1; 95 % CI 1⋅34, 3⋅28). The present study found that CD4 count, WHO clinical stage, cotrimoxazole prophylaxis therapy and MUAC were significantly associated with anaemia in children on ART. Therefore, continuous screening of anaemia and nutritional treatment is essential in these patients.

Iron status among HIV-infected adults during the first year of antiretroviral therapy in Tanzania

BACKGROUND

The influence of inflammation on iron status among people living with HIV (PLWHIV) has not been well explored. We evaluated the trajectory of iron status among PLWHIV during the first year of highly active antiretroviral therapy (HAART), compared alternative approaches for inflammation correction, and assessed the associations of iron status with HIV-1 viral load and anthropometric outcomes.

METHODS

We conducted a secondary analysis of data from a randomized trial among 400 adults initiating HAART in Tanzania. Ferritin and C-reactive protein (CRP) were measured at baseline, 1, 6 or 12 months. Ferritin was considered in four ways: unadjusted, and adjusted for inflammation using higher cut-off (HC), Thurnham-corrected (TC) and regression-corrected (RC) approaches. For unadjusted, TC and RC ferritin, iron deficiency (ID) was defined using ferritin < 15 μg/L and elevated iron status was defined using ferritin > 150 μg/L among females and > 200 μg/L among males. For HC ferritin, elevated iron status was defined based on serum ferritin > 500 μg/L, while ID was defined using ferritin < 70 μg/L in the presence of inflammation and < 15 μg/L in the absence of inflammation. Regression models evaluated the trajectory of ferritin concentration across categories of baseline characteristics, and assessed the association of iron status with viral and anthropometric outcomes.

RESULTS

The prevalence of iron deficiency at HAART initiation was 9% for unadjusted, 17% for HC, 12% for TC and 22% for RC ferritin. The prevalence of elevated iron status was 42% for unadjusted, 18% for HC, 31% for TC, and 15% for RC ferritin. The prevalence of iron deficiency for all three methods increased during the first year of HAART, while the prevalence of elevated iron status decreased. Baseline elevated iron status defined using HC ferritin was associated with a greater risk of HIV-1 viral load > 1000 copies/mL [relative risk (RR) = 4.29, 95% CI: 1.38-13.3] and incidence of being underweight [body mass index (BMI) < 18.5 kg/m2 , hazard ratio (HR) = 3.65, 95% confidence interval (CI): 1.38-9.67]. Neither baseline-elevated iron status defined using TC or RC ferritin nor baseline iron deficiency defined using any of the three methods was associated with HIV-1 viral load or anthropometric outcomes.

CONCLUSIONS

Whether and how inflammation correction is done influences findings of studies of iron status among PLWHIV.

Magnitude and Factors Associated with Cytopenia Among Children on Highly Active Antiretroviral Therapy at Hawassa University College of Medicine and Health Science, Sidama Region, Southern Ethiopia

Background

The most common abnormality in HIV-infected children is cytopenia, a hematological complication characterized by a decline in any of the blood cell lines. It is associated with a higher risk of morbidity and mortality. Therefore, this study aimed to assess the prevalence and associated factors of cytopenia among HIV-positive children on highly active antiretroviral therapy (HAART).

Methods

Hospital-based cross-sectional study design was conducted on HIV-positive children on HAART from July to September 2020. Socio-demographic and clinical characteristics of the study participants' data were collected using a structured questionnaire. Hematological parameters from the blood sample were analyzed using Ruby Cell-Dyne 300 hematology auto-analyzer. The data were analyzed using SPSS version 20. Logistic regression was used to assess the predictors of cytopenia among the study participants. P-values of less than 0.05 are considered statistically significant.

Results

Two hundred seventy-three HAART-experienced children were enrolled in this study, and 50.9% were females. At baseline, 40.7% of children were anemic. The overall magnitude of cytopenia among the study participants was 26.7%. The prevalence of anemia, thrombocytopenia, leucopenia and neutropenia among children was 11.4%, 4.0%, 14.3%, and 18.3%, respectively. Patients with an undetectable viral load (AOR = 0.5, CI = 0.3-0.9) are 50% less likely to report cytopenia. HAART-experienced children living in rural areas are more likely to develop cytopenia (AOR = 2.6, CI = 1.3-5.2) than those living in urban areas.

Conclusion

Hematologic abnormalities are common problems among children on highly active antiretroviral therapy. Therefore, routine investigation of hematological and immunological changes following appropriate therapeutic interventions is recommended.

Iron supplementation and paediatric HIV disease progression: a cohort study among children receiving routine HIV care in Dar es Salaam, Tanzania

BACKGROUND

Anaemia is common among HIV-infected children and iron supplementation is prescribed routinely for the prevention and management of anaemia among children. Limited evidence suggests iron supplementation may have adverse effects among HIV-infected populations. We aimed to estimate the effect of iron supplement use on mortality, disease progression and haematological outcomes among HIV-infected children in Dar es Salaam, Tanzania.

METHODS

A prospective cohort study was conducted among HIV-infected children (aged 0-14 years) receiving antiretroviral treatment or supportive care between October 2004 and September 2014. Clinical data were recorded on morbidity and vital status, haematological status and prescriptions at each clinical visit. Cox proportional hazards models adjusted for time-varying covariates were used to estimate the association of time-varying iron supplementation on the hazard rate of mortality, HIV disease stage progression, tuberculosis incidence and anaemia and microcytosis persistence.

RESULTS

In all, 4229 children were observed during 149 260 clinic visits for a mean follow-up of 2.9 years. After adjustment for time-varying clinical covariates, time-varying iron supplementation was associated with a 2.87 times higher hazard rate of mortality (95% CI: 1.70, 4.87) and a 1.48 times higher hazard rate of HIV disease stage progression (95% CI: 1.10, 1.98). Iron supplementation was also associated with a lower rate of anaemia persistence (HR = 0.47; 95% CI: 0.37, 0.61). No differences in the association between iron supplementation and clinical outcomes were observed by antiretroviral therapy or anaemia status.

CONCLUSIONS

Iron supplementation may increase the risk of HIV disease stage progression and mortality among HIV-infected children, while reducing the risk of anaemia.

Prevalence of anemia among people living with HIV: A systematic review and meta-analysis

BACKGROUND

Anemia is the most frequent hematologic abnormality among people living with human immunodeficiency virus (HIV) (PLWHIV) and is associated with HIV disease progression and higher risk of mortality of the patients. However, there is a wide variation of the prevalence of anemia among PLWHIV in different clinical settings. We aimed to obtain more precise estimates of prevalence of anemia and severity of anemia among PLWHIV, which may be important for patients, caregivers, researchers and health policy-makers.

METHODS

We systematically searched PubMed, EMBASE, Web of Science, and Cochrane Library for original articles reporting the prevalence of anemia defined using age and sex-specific hemoglobin levels according to World Health Organization criteria among PLWHIV from inception to August 31, 2021. We used DerSimonian-Laird random-effects meta-analyses to obtain pooled prevalence and 95% confidence intervals (CIs) of anemia and severity of anemia among PLWHIV. A univariable meta-regression has been conducted to assess the association between anemia prevalence and study characteristics, including study design, median year of sampling, geographical region, World Bank Income level, and proportion of antiretroviral therapy (ART).

FINDINGS

We included 63 observational studies covering 110,113 PLWHIV. The pooled prevalence of anemia was 39.7% (95% CI: 31.4%-48.0%) for children living with HIV aged <15 years, 46.6% (95% CI: 41.9%-51.4%) for adults (men and non-pregnant women) living with HIV aged ≥15 years, and 48.6% (95% CI: 41.6%-55.6%) for pregnant women living with HIV. Among adults living with HIV, the pooled prevalence of severity of anemia was 21.6% (95% CI: 19.9%-23.3%), 22.6% (95% CI: 14.8%-30.4%), and 6.2% (95% CI: 4.4%-8.1%) for mild, moderate and severe anemia, respectively. Compared with East Africa, anemia prevalence among adults living with HIV was higher in Southern Africa (p = 0.033).

INTERPRETATION

Anemia is prevalent among PLWHIV. Thus, policies, strategies, and programs should be considered to identify the predictors of anemia among PLWHIV to reduce the burden of anemia among patients in the ART era.

The effect of oral iron supplementation on the gut microbiota, gut inflammation, and iron status in iron-depleted South African school-age children with virally suppressed HIV and without HIV

PURPOSE

Both HIV and oral iron interventions may alter gut microbiota composition and increase gut inflammation. We determined the effect of oral iron supplementation on gut microbiota composition, gut inflammation, and iron status in iron-depleted South Africa school-aged children living with HIV (HIV+) but virally suppressed on antiretroviral therapy and children without HIV (HIV-ve).

METHODS

In this before-after intervention study with case-control comparisons, we provided 55 mg elemental iron from ferrous sulphate, once daily for 3 months, to 33 virally suppressed (< 50 HIV RNA copies/mL) HIV+ and 31 HIV-ve children. At baseline and endpoint, we assessed microbial composition of faecal samples (16S rRNA sequencing), and markers of gut inflammation (faecal calprotectin), anaemia (haemoglobin) and iron status (plasma ferritin, soluble transferrin receptor). This study was nested within a larger trial registered at clinicaltrials.gov as NCT03572010.

RESULTS

HIV+ (11.3y SD ± 1.8, 46% male) and HIV-ve (11.1y SD ± 1.7, 52% male) groups did not significantly differ in age or sex ratio. Following iron supplementation, improvements were observed in haemoglobin (HIV+ : 118 to 124 g/L, P = 0.003; HIV-ve: 120 to 124 g/L, P = 0.003), plasma ferritin (HIV+ : 15 to 34 µg/L, P < 0.001; HIV-ve: 18 to 37 µg/L, P < 0.001), and soluble transferrin receptor (HIV+ : 7.1 to 5.9 mg/L, P < 0.001; HIV-ve: 6.6 to 5.7 mg/L, P < 0.001), with no significant change in the relative abundance of any genera, alpha diversity of the gut microbiota (HIV+ : P = 0.37; HIV-ve: P = 0.77), or faecal calprotectin (HIV+ : P = 0.42; HIV-ve: P = 0.80).

CONCLUSION

Our findings suggest that oral iron supplementation can significantly improve haemoglobin and iron status without increasing pathogenic gut microbial taxa or gut inflammation in iron-depleted virally suppressed HIV+ and HIV-ve school-age children.

Time to detection of anemia and its predictors among children living with HIV at Debre Tabor and University of Gondar Compressive Specialized Hospitals, 2020: a multicentre retrospective follow-up study

BACKGROUND

Even though antiretroviral therapy access for HIV infected children increased dramatically, anemia have been continued as a challenge regardless of a cluster of differentiation (CD4) count and viral load. Hence, this study aimed to assess the time to detection of anemia and its predictors among children living with HIV at Debre Tabor and university of Gondar compressive specialized hospital, 2020.

METHODS

A retrospective follow-up study was conducted from January 2010 to December 2018. A total of 372 children under the age of 15 who had received ART were included in the study. Data were collected from children's medical charts and ART registration logbook using a standard checklist. Besides, the data were entered into Epi data 4.2.2 and then exported to Stata 14.0 for further analysis. The Cox regression model, the variables having P-value ≤.05 with 95% CIs in multivariable analysis were declared as statistically significant for anemia.

RESULT

The mean (±SD) of follow-up periods were 56.6 ± 1.7 SD months. The overall median survival time free from anemia was 137 months, and the incidence rate of anemia was 6.9 per 100 PYO (95% CI: 5.3, 7.8). Moreover, WHO clinical staging of III/IV [AHR: 4.2, 95% CI: 1.80, 11.1], low CD4 count below threshold [AHR: 1.9, 95% CI: 1.09, 3.37], cotrimoxazole preventive therapy non-users, and poor level of adherence [(AHR: 2.4, 95% CI: 1.20, 4.85] were the main predictors of the time to detection of anemia.

CONCLUSION

The incidence rate of anemia in our retrospective cohort was high. The risk of anemia is present in children living with HIV infection but the risk for anemia is increased based on (WHO clinical staging III and IV, CD4 count below the threshold level, CPT non-users, and poor level of adherence). Since many of these risk factors are present routinely, even within one single patient, our clinical monitoring for anemia quarterly was fully justified as was our routine switch from standard therapies such as AZT to another regimen upon lab confirmation of anemia. Additional methods to improve cotrimoxazole preventative therapy and level of adherence are also needed.

Examining Associations of HIV and Iron Status with Nutritional and Inflammatory Status, Anemia, and Dietary Intake in South African Schoolchildren

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

Magnitude and associated factors of peripheral cytopenia among HIV-infected children attending at University of Gondar Specialized Referral Hospital, Northwest Ethiopia

BACKGROUND

Isolated or multi lineage cytopenia are the most common clinicopathological features and independently associated with increased risk of disease progression and death among human immunodeficiency virus infected children. In the study area, there is scarcity of data about the magnitude of various cytopenia.

OBJECTIVES

Aimed to determine the magnitude and associated factors of peripheral cytopenia among HIV infected children at the University of Gondar Specialized Referral Hospital ART clinic, Northwest Ethiopia.

METHODS

Institutional based cross-sectional study was conducted on 255 HIV infected children from January- April 2020. None probable convenient sampling technique was used to select the study participant. Socio demographic data were collected by pre tested structured questionnaire via face-to-face interview and their medical data were obtained from their follow-up medical records. Moreover, blood specimens were collected and examined for complete blood count, viral load and blood film, whereas stool specimens were collected and examined for intestinal parasites. Bi-variable and multi-variable logistic regression models were fitted to identify associated factors of cytopenia. P-Value <0.05 was considered as statistically significant.

RESULT

The overall magnitude of peripheral cytopenia was 38.9%. Anemia, leukopenia, lymphopenia, thrombocytopenia and bi-cytopenia were 21.2%, 12.2%, 11%, 1.6% and 3.9% respectively. Being in the age group of 2-10 years (AOR = 5.38, 95%CI 2.33-12.46), AZT based regimen (AOR = 5.44, 95%CI: 2.24-13.21), no eating green vegetables (AOR = 2.49, 95% CI: 1.26-4.92) and having plasma viral load >1000 copies /ml (AOR = 5.38, 95%CI: 2.22-13.03) showed significant association with anemia.

CONCLUSION

Anemia was the predominant peripheral cytopenia among HIV infected children in this study. It was strongly associated with AZT based drug type, age below 10 years and high viral load. Critical stress should be given for early investigation and management of cytopenia in addition to the use of alternative drug which leads to higher viral suppression and lower risk of toxicity issue.

Predictors of Anemia Among HIV-Infected Children on Antiretroviral Therapy in Wolaita Zone, South Ethiopia: A Facility-Based Cross-Sectional Study

Purpose

Anemia is a global public health problem, and the majority of human immunodeficiency virus (HIV)-positive people become anemic at some point in the course of the disease. We lack adequate evidence on the magnitude of anemia among children on highly active antiretroviral therapy in Ethiopia and particularly in South Ethiopia. Thus, this study aimed at determining the proportion and associated factors of anemia among children on highly active antiretroviral therapy in Wolaita zone, South Ethiopia.

Patients and Methods

A facility-based cross-sectional study was conducted from November to December 2018 on 256 children from 6 months to 14 years of age who were on antiretroviral therapy. Data were collected through an interview with caregivers and review of medical records. CD4+ cell count was analyzed using FACS Calibur, and hemoglobin level was measured with a Hem cue 301 analyzer. Stool samples were examined for the presence of intestinal parasites by direct wet mount technique. Data analyzed with Stata version 14.0 were conveyed in mean and standard deviation of the mean, median and inter-quartile range. Multivariate analysis was carried out to identify independent predictors of the outcome variable. Adjusted odds ratio with 95% confidence interval was reported.

Results

The proportion of anemia was found to be 38.8%. Co-trimoxazole prophylaxis (AOR=0.45; 95% CI: 0.21, 0.95), caregivers not receiving nutritional counseling (AOR=0.90; 95% CI: 0.01, 0.98) and presence of intestinal parasites (AOR=3.10; 95% CI: 1.39, 6.88) were associated with anemia.

Conclusion

The proportion of anemia found in this study is a moderate public health problem. Health education programs in antiretroviral therapy clinics should be targeted at appropriate dietary practice, and appropriate hand washing and other hygienic practices to prevent intestinal parasitic infections. Co-trimoxazole prophylaxis should be given to all eligible children based on the recommendation.

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.

Nutritional status and dietary diversity of school-age children living with HIV: a cross-sectional study in Phnom Penh, Cambodia

Background

HIV/AIDS continues to be a major public health concern for children. Each day, worldwide, approximately 440 children became newly infected with HIV, and 270 children died from AIDS-related causes in 2018. Poor nutrition has been associated with accelerated disease progression, and sufficient dietary diversity is considered a key to improve children’s nutritional status. Therefore, this study aims to 1) examine nutritional status of school-age children living with HIV in Phnom Penh, Cambodia, and 2) identify factors associated with their nutritional status, especially taking their dietary diversity into consideration.

Methods

This cross-sectional study was conducted in May 2018 within the catchment area of the National Pediatric Hospital, Cambodia. Data from 298 children and their caregivers were included in the analyses. Using semi-structured questionnaires, face-to-face interviews were conducted to collect data regarding sociodemographic characteristics, quality of life, and dietary diversity. To assess children’s nutritional status, body weight and height were measured. Viral load and duration of antiretroviral therapy (ART) were collected from clinical records. Multiple logistic regression analyses were performed to identify factors associated with stunting and wasting.

Results

Of 298 children, nearly half (46.6%) were stunted, and 13.1% were wasted. The mean number of food groups consumed by the children in the past 24 h was 4.6 out of 7 groups. Factors associated with children’s stunting were age (adjusted odds ratio [AOR] 2.166, 95% confidence interval [CI]: 1.151, 4.077), household wealth (AOR 0.543, 95%CI: 0.299, 0.986), duration of receiving ART (AOR 0.510, 95%CI: 0.267, 0.974), and having disease symptoms during the past 1 year (AOR 1.871, 95%CI: 1.005, 3.480). The only factor associated with wasting was being male (AOR 5.304, 95%CI: 2.210, 12.728).

Conclusions

Prevalence of stunting was more than double that of non-infected school-age children living in urban areas in Cambodia. This highlights the importance of conducting nutritional intervention programs, especially tailored for children living with HIV in the country. Although dietary diversity was not significantly associated with children’s nutritional status in this study, the findings will contribute to implementing future nutritional interventions more efficiently by indicating children who are most in need of such interventions in Cambodia.

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.

Determinants of Anemia among HIV-Positive Children on Highly Active Antiretroviral Therapy Attending Hospitals of North Wollo Zone, Amhara Region, Ethiopia, 2019: A Case-Control Study

Introduction. Anemia is one of the most commonly observed hematological abnormalities and an independent poor prognostic marker of HIV disease. The rate of progression and mortality in this subgroup of patients is high compared to nonanemic patients. WHO estimates that over two billion people are anemic worldwide and young children bear the world's highest prevalence rate of anemia. In Ethiopia, there is limited information about the determinant factors associated with anemia among HIV positive children. Thus, this study aimed to determine the determinant factors of anemia among HIV-infected children on HAART.

Essential trace elements and progression and management of HIV infection

This review was written to update the review that we published in Nutrition Research in 2007 by examining studies published in the last 11 years which describe the effects of trace mineral deficiencies and micronutrient supplementation on HIV infection and its progression. In addition, we included studies that explore the interactions between Highly Active Anti-Retroviral Therapy (HAART) and micronutrient nutrition, focusing on the essential trace minerals. This review summarizes the results described in relevant articles that were identified by literature searches conducted using the OVID Medline database. Four of the nine essential trace minerals, specifically chromium, iron, selenium, and zinc, can influence HIV progression and/or its treatment. Notably, copper-containing filters may prevent transmission of the HIV virus via breastfeeding. However, there is a lack of good evidence to date that fluoride, iodine, manganese, or molybdenum influence HIV infection. Recent studies reveal that HAART can alter serum trace mineral and vitamin concentrations, but the effects vary based on the medications used. Although they have contributed useful new data, the sample sizes for most of these studies were too small to draw definitive conclusions for introducing changes in the management of HIV infection. Larger studies are needed to better understand and define the roles of trace mineral and vitamin deficiencies and micronutrient supplementation in the management and treatment of HIV-infected patients.

Hematologic abnormalities and associated factors among HIV infected children pre- and post-antiretroviral treatment, North West Ethiopia

INTRODUCTION

There are few studies on the hematologic parameters of HIV-infected individuals in Ethiopia; of these, almost all studies researched adults. Our current study is unique in that it mainly focused on the pediatric population and compared both pre- and post-antiretroviral therapy (ART) children. Inference from this study can be used for other developing countries where the burden of HIV disease is high.

OBJECTIVE

The aim of this study was to identify hematologic abnormalities in HIV-infected children before and after initiation of ART.

METHODOLOGY

A cross-sectional study was conducted on HIV-infected children from June 1 to August 30, 2015. Data were collected using a pretested and structured questionnaire. Statistical analysis was performed using SPSS 20 version.

RESULTS

The median age of study subjects was 10 years with an interquartile range (IQR) of (6, 12). Two-thirds (74.3%) of study subjects received ART for >1 year. The median of CD4 count before ART was 490 cells/mm³ with an IQR of (286, 765); this increased to 663 cells mm³ with an IQR of (499, 908) after ART. Likewise, the median of hemoglobin before ART was 11.5 mg/dL with an IQR of (9.9, 13), which increased after ART to 13 mg/dL with an IQR of (11.8, 14). The prevalence of anemia was 42.8% before and 18.9% after ART initiation. The median of absolute neutrophil count before ART was 3×10³ with an IQR of (2.1, 4.6) and after ART, it became 3×10³ with IQR of (1.9, 4.2). Age <5 years (adjusted odds ratio [AOR]: 2.76; 95% CI: 1.5, 5.0), an advanced stage of AIDS (AOR: 2.8; 95% CI: 1.4, 5.6) and CD4% <25% (AOR: 2.4; 95% CI: 1.2, 4.9) were significantly associated with anemia before ART initiation, while opportunistic infections were associated with anemia after initiation of ART (AOR: 2.3; 95% CI: 1.08, 4.8).

CONCLUSION

ART positively or negatively affects the hematologic profile of HIV-infected children. The current study demonstrated a significant reduction of anemia after initiation of ART.

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.
