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

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.

The prevalence of thrombocytopenia and leucopenia among people living with HIV/AIDS in Ethiopia: A systematic review and meta-analysis

INTRODUCTION

Thrombocytopenia and leucopenia are frequently encountered hematological disorders among people living with HIV/AIDS. This systematic review and meta-analysis were aimed to indicate the national prevalence of thrombocytopenia and leucopenia among HIV/AIDS patients.

METHODS

This systematic review and meta-analysis was conducted following the preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines. A systematic search was conducted from February 01, 2021 to April 02, 2021 using electronic databases Google Scholar, PubMed, Web of Sciences, Google, EMBASE, SCOPUS and ResearchGate. The quality of the included studies was assessed using Newcastle-Ottawa Quality Assessment Scale (NOS) adapted for cross-sectional studies. Data analysis was done using STATA version 14 using metan commands. Random effect meta-analysis was used to estimate the pooled prevalence of thrombocytopenia and leucopenia among people living with HIV/AIDS in Ethiopia.

RESULT

Of the 349 initially searched articles, 90 were assessed for eligibility and only 13 articles published from 2014 to 2020 were included in the final meta-analysis. A total of 3854 participants were involved in the included studies. The pooled prevalence of thrombocytopenia was 9.69% (95%CI; 7.40-11.97%). Significant heterogeneity was observed with I2 value of 84.7%. Thrombocytopenia was 11.91% and 5.95% prevalent among HAART naive and HAART exposed HIV/AIDS patients, respectively. The pooled prevalence of leucopenia among HIV/AIDS patients was 17.31% (95%CI: 12.37-22.25%).

CONCLUSION

This study showed a high prevalence of thrombocytopenia and leucopenia among people living with HIV/AIDS, indicating the necessity of regular screening of HIV seropositive patients for different hematological parameters and providing treatment.

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.

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.

Burden of anemia and its association with HAART in HIV infected children in Ethiopia: a systematic review and meta-analysis

Background

Anemia is a common problem in HIV (human immunodeficiency virus) infected patients, and is associated with decreased functional capacity and quality of life. Ethiopia is one of the countries which has expanded highly active antiretroviral treatment (HAART) over the past years. The effect of HAART on anemia among HIV remains inconsistent and inconclusive, particularly in children. This study thus aimed to synthesize the prevalence of anemia among HIV infected Ethiopian children and its association with HAART initiation.

Methods

MEDLINE/PubMed, EMBASE, PsycINFO, Web of Science and Google scholar were used to identify 12 eligible studies reporting an association between anemia and HIV using a priori set criteria. PRISMA guideline was used to systematically review and meta-analysis these studies. Details of sample size, magnitude of effect sizes, including odds ratio (OR) and standard errors were extracted. Random-effects model was used to calculate the pooled estimates using STATA/SE version-14. I² and meta-bias statistics assessed heterogeneity and publication bias of the included studies. Sub-group analyses, based on study designs, were also carried out.

Results

In Ethiopia, the overall prevalence of anemia in HIV infected children was 22.3% (95% CI: 18.5–26.0%). The OR of anemia-HIV/AIDS comorbidity was 0.4 (95% CI, 0.2–0.5) in HAART initiated children as compared to non-initiated counterparts. Meta-bias and funnel plot detected no publication bias.

Conclusion

On aggregate, anemia is a common comorbidity in pediatric HIV patients. HAART was significantly associated with a reduced anemia-HIV/AIDS comorbidity. Prompt start of HAART might help decreasing the prevalence of anemia and its subsequent complications.
