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

Predictors of anemia among HIV-infected children in Ethiopia: systematic review and meta-analysis

Anemia continues to be one of the common complications among HIV-infected children. In Ethiopia, though there is a systematic review and meta-analysis study on anemia among HIV-infected children, it only disclosed the effect Highly Active Antiretroviral Treatment on HIV/AIDS-anemia comorbidity, and yet, the meta effect of other potential factors such as type of ART, presence of opportunistic infection, advanced stage of HIV/AIDS, and cotrimoxazole therapy on HIV/AIDS-anemia comorbidity have not been explored in the previous review. Therefore, this systematic review and meta-analysis aimed to identify the factors associated with anemia among HIV-infected children. Moreover, this study provides an up-to-date pooled estimate of anemia among HIV-infected children in Ethiopia. We systematically searched PubMed, HINARI, Science Direct, Cochrane Library, Google Scholar, and African Journals Online on February 3, 2024, to identify relevant primary research articles. The Briggs Institute (JBI) Checklist was used to check the quality of the original studies. Meta package for proportions (Metapro) was used to estimate the pooled prevalence of anemia among HIV-infected children using the random-effects model. Heterogeneity across studies was checked using the I-square test. Funnel plots visual inspection and Egger's tests were done to detect publication bias. The pooled prevalence of anemia among HIV-infected children in Ethiopia was 23.79% (95% CI 17.28, 31.81). Age < 7 years (OR 3.71, 95% CI 2.58; 5.33), advanced HIV disease (OR 2.78, 95% CI 2.00; 3.87), intestinal parasitic infection (OR 2.28, 95% CI 1.02; 5.09), poor ART treatment adherence (OR 1.96, 95% CI 1.23; 3.10), opportunistic infection (OR 2.81, 95% CI 1.59; 4.95), viral load > 1000 copies/ml (OR 4.29, 95% CI 2.28; 8.09), and zidovudine containing regimen (OR 5.07, 95% CI 2.41; 10.64) were identified as factors associated with a higher risk of anemia. Whereas, cotrimoxazole prophylaxis therapy (OR 0.49, 95% CI 0.35; 0.72) reduces the risk of anemia among HIV-infected children. In Ethiopia, anemia remains a public health concern among children living with HIV. Therefore, regular screening and management of anemia are important for HIV-infected children, particularly for those with advanced HIV disease, opportunistic infection, high viral load, and who are taking zidovudine-containing regimens for better clinical outcomes. Moreover, preventive chemotherapy (deworming) and counseling on infection prevention should be provided for children living with HIV to prevent parasitic infection.

Effects of HIV exposure on anemia and vitamin D nutritional status in children aged 6-24 months: a hospital-based cross-sectional study

There is little research on anemia and vitamin D deficiency in HIV-exposed uninfected (HEU) children. This study was aimed to describe and compare the prevalence of anemia and vitamin D inadequacy in HEU children and HIV-unexposed uninfected (HUU) children, and to examine the associations of HIV exposure with anemia and vitamin D inadequacy. This was a hospital-based descriptive cross-sectional study nested within the Prevention of Mother-to-Child Transmission (PMTCT) of HIV program in Hunan Province during July and September 2022. The HEU children aged 6 to 24 months were recruited from the PMTCT outpatient clinics located in five Municipal Maternal and Child Health Care Hospitals. The HUU children were recruited from routine child health examination clinics in the same five Hospitals. Questionnaires about children's characteristics and maternal gestational conditions were collected from children's caregivers, and blood samples were collected from all children. Descriptive statistics, Chi-square test, non-parametric rank sum test, and logistic regression were used for analysis. The study population included 336 HEU children and 334 HUU children. The overall prevalence of anemia in the HEU and HUU children was 10.4% and 8.1%, respectively. The median hemoglobin concentrations were 120 (115-126) g/L in the HEU children and 122 (116-129) g/L in the HUU children. Neither prevalence of anemia nor hemoglobin concentration was significantly different between the two groups (P > 0.05). The prevalence of vitamin D inadequacy in the HEU children (19.6% for deficiency and 25.0% for insufficiency) was significantly higher than that of the HUU children (11.4% for deficiency and 16.2% for insufficiency) (P < 0.001). The median 25(OH)D concentration in the HEU children was significantly lower than that of the HUU children (23.80 (13.50-34.08) vs. 32.08 (18.60-39.32) ng/ml) (P < 0.001). HIV exposure in HEU children was significantly associated with an increased risk of vitamin D deficiency (adjusted OR (AOR) 1.72, 95% CI: 1.13-2.61) and vitamin D insufficiency (AOR 1.53, 95% CI: 1.01-2.34), but not with anemia (AOR 0.80, 95% CI: 0.32-2.01). The PMTCT program shall strengthen vitamin D supplementation in HEU children and caregivers shall appropriately extend the outdoor activity time of HEU children to reduce the occurrence of vitamin D inadequacy.

Magnitude of anemia and associated factors among HIV infected children on antiretroviral therapy in Awi zone health facilities, Northwest Ethiopia, 2023

BACKGROUND

Anemia is a common complication of HIV infected children and it is enabling HIV disease progression, and decreasing survival. In Ethiopia, there is limited evidence on the prevalence of anemia and its associated factors among HIV infected children particularly in the Awi Zone. Therefore, this study aimed to assess the magnitude and associated factors of anemia among HIV infected children on ART aged from 6 months to 15 year-old in ART Clinic, Awi-Zone, Ethiopia.

OBJECTIVE

To assess the magnitude and associated factors of anemia among HIV infected children on antiretroviral therapy in Awi zone health facilities, Northwest, Ethiopia, 2022.

METHODS

A facility based cross-sectional study design was conducted from October to December 2022. A simple random sampling method was used to select the study participants. Descriptive statistics, including frequencies and proportions was used to summarize the study variables and data had been entered in to Epi data 4.2 and exported to SPSS version 25. Bivariable logistic regression followed by multivariable logistic regression was performed. Degree of association between dependent and independent variables had been assessed using adjusted odds ratio with 95% CI at p value of ≤ 0.05.

RESULT

From 346 participants in the selected sample 339 (97.9%) of them responded. Prevalence of anemia was 13.3% (n = 45) among which, majority (44.4%) of them had mild anemia, while about (42.2%,) had moderate anemia and around 13.3%, of them were severely anemic. Baseline CD4 count (AOR = 6.58, 95% CI: 2.85-15.22), WHO clinical stage III or IV (AOR = 8.42, 95% CI = 3.47, 20.45), hookworm infection (AOR = 5.06, 95% CI = 2.04, 12) and malaria infection (AOR = 4.92, 95% CI (2.19-11.02) were significantly associated with anemia among children on HAART.

CONCLUSION

The prevalence of anemia among participants was relatively low in this study. However, a considerable proportion of participants had moderate to severe anemia. Lower CD4 count at enrolment, advanced HIV clinical stage, malaria and hookworm infection were significantly linked with anemia. Thus, it requires regular monitoring of anemia status in these patients for better clinical outcomes and quality of life improvements.

Prevalence and factors related to anaemia in children aged 6-59 months attending a quaternary health facility in Maputo, Mozambique

Globally, anaemia prevails as a public health issue, being also a concern in Mozambique, where about two-thirds of children 6-59 months of age are affected by this condition. We carried out this study to estimate anaemia prevalence and evaluate structural determinants and haematological parameters association among children aged 6-59 months attending pediatric inpatient and outpatient services in a Quaternary Health Facility in Maputo City Province, Mozambique. We collected data from 637 inpatients or outpatients who attended pediatric consultations at the Maputo Central Hospital. The overall rate of anaemia in children aged 6-59 months was 62.2% (396/637), with 30.9% moderate anaemia (197/637), 23.9% mild anaemia (152/637), and 7.4% severe anaemia (47/637). Among our study participants, critical factors for anaemia were those concerning the age group, child´s caregiver schooling, malaria and size of the liver.
