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

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.

Incidence of anaemia and its predictors among HIV-infected children receiving highly active antiretroviral treatment in North-West Ethiopia: a multicentre retrospective follow-up study

BACKGROUND

Anaemia is one of the most common problems in HIV-infected patients associated with increased HIV progression, decreased functional capacity, survival and quality of life. For better interventions, up-to-date information concerning anaemia among HIV-infected children less than 5 years of age on antiretroviral therapy (ART) is vital. Thus, this study aims to determine the predictors of anaemia among HIV-infected children less than 5 years of age receiving ART in North-West Ethiopia.

DESIGN

An institution-based retrospective follow-up study was conducted.

STUDY SETTING

Amhara region Comprehensive Specialized Hospitals, North-West Ethiopia.

PARTICIPANTS

In total, we examined 460 HIV-infected children less than 5 years of age who had followed highly active antiretroviral treatment from 2010 to 2020.

OUTCOME MEASURES

The outcome measures were median time to detection of anaemia, the incidence and the effects of cotrimoxazole preventive therapy (CPT), ART adherence, tuberculosis (TB), WHO clinical stage and wasting on anaemia.

RESULTS

The overall follow-up time was 9234 person-months of observation. The incidence density of anaemia was 8.34 per 1000 person-months of observation (95% CI 6.67 to 10.43). The cumulative survival probability of children after the last months of follow-up was 0.54. The independent predictors of anaemia were not receiving CPT (adjusted HR (AHR)=4.44; 95% CI 2.48 to 7.93), poor adherence to ART (AHR=2.46; 95% CI 1.37 to 4.42), TB (AHR=3.40; 95% CI 1.72 to 6.72), severe WHO clinical stage (AHR=3.03; 95% CI 1.40 to 6.58) and severe wasting (AHR=1.98; 95% CI 1.08 to 3.64).

CONCLUSION AND RECOMMENDATION

The incidence rate of anaemia was high and it was provoked by predictors like CPT, ART adherence, TB, WHO clinical stage and wasting. Therefore, it is necessary to emphasise for these predictors.

Mortality and its predictors among human immunodeficiency virus-infected children younger than 15 years receiving antiretroviral therapy in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Despite antiretroviral treatment (ART), the human immunodeficiency virus (HIV) continues to pose a considerable health burden in resource-poor countries. This systematic review and meta-analysis aimed to determine the pooled incidence density of mortality and identify potential predictors among HIV-infected children receiving ART, from studies conducted in various parts of Ethiopia.

METHODS

A comprehensive database search was made in Excerpta Medica, PubMed, Web of Science, African Journals Online, Google Scholar, and Scopus. We reported results following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis 2020. Excel Spreadsheet and STATA Version 14 software were used for data abstraction and meta-analysis, respectively. Statistical heterogeneity among studies was assessed using I2 statistics. Meta-regression and subgroup analysis were performed to further explore the sources of statistical heterogeneity. Moreover, publication bias and a leave-out-one sensitivity analysis were performed.

RESULTS

Twenty-two articles involving 8,731 participants met inclusion criteria and were included. The pooled incidence density of mortality was 3.08 (95% confidence interval (CI), 2.52 to 3.64) per 100 child years. Predictors of mortality were living in rural areas (hazard ratio (HR), 2.18 [95% CI, 1.20 to 3.98]), poor adherence to ART (HR, 2.85 [ 95% CI, 1.39 to 5.88]), failure to initiate co-trimoxazole preventive therapy (HR, 2.16 [95% CI, 1.52 to 3.07]), anemia (HR, 2.28 [95% CI, 1.51 to 3.45]), opportunistic infections (HR, 1.52 [ 95% CI, 1.15 to 2.00]), underweight (HR, 1.74 [95% CI, 1.26 to 2.41]), wasting (HR, 2.54 [95% CI, 1.56 to 4.16]), stunting (HR, 2.02 [95% CI, 1.63 to 2.51]), World Health Organization classified HIV clinical stages III and IV (HR, 1.71 [95% CI, 1.42 to 2.05]), and Nevirapine-based regimens (HR, 3.91 [95% CI, 3.09 to 4.95]).

CONCLUSIONS

This study found that the overall mortality rate among HIV-infected children after ART initiation was high. Therefore, high-level commitment and involvement of responsible caregivers, healthcare providers, social workers, and program managers are of paramount importance to identify these risk factors and thus enhance the survival of HIV-infected children receiving ART.

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.

The prevalence of anemia among human immunodeficiency virus-infected individuals in East Africa: A systematic review and meta-analysis

BACKGROUND

Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients face several hematological abnormalities. Of these abnormalities, anemia is the most common one. Africa has a high prevalence of HIV/AIDS, especially in the East and South African region, which is heavily affected by the virus. Therefore, this systematic review and meta-analysis aimed to determine the pooled prevalence of anemia among patients with HIV/AIDS in East Africa.

METHODS

This systematic review and meta-analysis was conducted based on the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. PubMed, Google Scholar, Science Direct, Dove Press, Cochrane Online, and African journals online were searched systematically. The quality of the included studies was assessed by 2 independent reviewers using the Joanna Briggs Institute critical appraisal tools. Data were extracted into an Excel sheet and then exported to STATA version 11 for analysis. A random-effect model was fitted to estimate the pooled prevalence and Higgins I2 test statistics were done to test the heterogeneity of studies. Funnel plots analysis and Egger-weighted regression tests were done to detect publication bias.

RESULTS

The pooled prevalence of anemia among HIV/AIDS patients in East Africa was 25.35% (95% CI: 20.69-30.03%). A subgroup analysis by highly active antiretroviral therapy (HAART) status showed that the prevalence of anemia among HAART naive HIV/AIDS patients was 39.11% (95% CI: 29.28-48.93%) whereas the prevalence among HAART experienced was 36.72% (95% CI: 31.22-42.22%). A subgroup analysis by the study population showed that the prevalence of anemia among adult HIV/AIDS patients was 34.48% (95% CI: 29.52-39.44%) whereas the pooled prevalence among children was 36.17% (95% CI: 26.68-45.65%).

CONCLUSION

This systematic review and meta-analysis revealed that anemia is among the most common hematological abnormalities in HIV/AIDS patients in East Africa. It also underscored the importance of taking diagnostic, preventive, and therapeutic measures for the management of this abnormality.

Comorbid disease in children and adolescents with perinatal HIV infection: A pilot study

Background. With the increased use of combination antiretroviral therapy, the mortality of people living with HIV has decreased significantly, which has led to an increase of comorbidity and secondary HIV-related pathology in both adults and also in children and adolescents living with HIV infection. The incidence of children and adolescents with HIV infection and those in the general population varies significantly.The aim. To assess the frequency and range of chronic comorbidities in children and adolescents with perinatal HIV infection Methods. We carried out an observational study. Data on the incidence of 161 children with perinatal HIV infection registered in the Irkutsk Regional AIDS Center were copied.Results. Overall incidence of tuberculosis (18633.5 per 100 000 children), diseases of the digestive system (24844.7 per 100 000 children), diseases of the eye and adnexa (28571.4 per 100 000 children), diseases of the nervous system (18012.4 per 100 000 children), mental and behavioral disorders (13,664.6 per 100 000 children) in children with perinatal HIV infection is the higher than in children of comparable age. The overall incidence values of the endocrine system diseases, eating and metabolic disorders, diseases of the ear and mastoid process, diseases of the circulatory system, diseases of the genitourinary system, as well as congenital disorders and chromosomal disorders in children and adolescents with and without perinatal HIV infection are comparable.Conclusion. The prevalence of diseases of the circulatory, respiratory and genitourinary systems in children with perinatal HIV infection is comparable to that in the corresponding population. Prevalence of tuberculosis, anemia, diseases of the gastrointestinal tract, diseases of the eye and adnexa, diseases of the nervous system, mental and behavioral disorders is higher compared to children not exposed to HIV.

Risk factors and prognostic significance of anemia in children with HIV infection on antiretroviral therapy

OBJECTIVES

To establish the incidence, risk factors and prognostic effect of anemia in children living with HIV (CLWH).

DESIGN

Retrospective nested case-control study of patients 0-18 years in five centers in sub-Saharan Africa, 2004-2014.

METHODS

Incident cases of anemia were identified from electronic records and matched with CLWH without anemia. We calculated the incidence density of anemia and used conditional logistic regression to evaluate its association with risk factors, stratified by severity and type of anemia. We used a Cox proportional hazards model to evaluate the impact of anemia on survival.

RESULTS

Two thousand, one hundred and thirty-seven children were sampled. The incidence density of anemia was 1 per 6.6 CLWH-years. Anemia was moderate in 31.8% and severe in 17.3% of anemia cases, which had 10-year mortality hazards of 3.4 and 4.5, respectively. Microcytic anemia (36% cases) was associated with 2.3-fold hazard of 10-year mortality, and with malnutrition and CD4 + suppression. Normocytic anemia (50.5% cases) was associated with 2.6-fold hazards of 10-year mortality, and with more severe malnutrition, CD4 + suppression, and WHO stage, but inversely associated with lamivudine and nevirapine therapy. Macrocytic anemia (13.5% cases) was neither associated with higher 10-year mortality nor with severe malnutrition or CD4 + suppression but was associated with WHO stage II/III and negatively associated with lamivudine therapy.

CONCLUSION

This large multicountry study of CLWH found a high incidence density of anemia. Higher severity, normocytic and microcytic types of anemia were independently associated with long-term mortality. Laboratory studies are needed to decipher the mechanisms of anemia and how it impacts mortality in CLWH.

Anaemia, iron and vitamin A status among South African school-aged children living with and without HIV

Background. Data on iron and vitamin A deficiency are scarce in school-aged children living with HIV (HIV+) compared with children without HIV (HIV–). Both deficiencies can contribute to anaemia. Objective. To assess anaemia, iron and vitamin A status in a sample of HIV+ and HIV– school-aged children in South Africa. Methods. In this comparative cross-sectional study, biomarkers for anaemia (haemoglobin), iron (plasma ferritin (PF), soluble transferrin receptor), vitamin A (retinol-binding protein (RBP)) and inflammatory status (C-reactive protein, α-1-acid glycoprotein) were measured in 8 - 13-year-old children from Cape Town living with (n=143) and without HIV (n=148). Measurements of PF and RBP were adjusted for inflammation using a regression-correction approach. Results. HIV+ children had higher prevalences of anaemia (29% v. 14%; odds ratio (OR) = 2.6; 95% confidence interval (CI) 1.4 - 4.9; p=0.002), iron-deficient erythropoiesis (20% v. 9%; OR=2.5; 95% CI 1.2 - 5.0; p=0.013) and iron deficiency anaemia (11% v. 4%; OR=2.9; 95% CI 1.1 - 7.7; p=0.035) than HIV– children. Marginal vitamin A deficiency was noted in 52% of HIV+ and 57% of HIV– children (p=0.711). Subclinical inflammation was more prevalent in HIV+ than HIV– children (p=0.012). Conclusion. Anaemia, iron-deficient erythropoiesis and iron deficiency anaemia were more prevalent in HIV+ than HIV– children. Prevalence of marginal vitamin A deficiency was high in both groups. Efforts to improve micronutrient status and mitigate nutritional determinants of anaemia in HIV+ children from resource-limited settings should be prioritised.

Half-life time prediction of developing first-line antiretroviral treatment failure and its risk factors among TB and HIV co-infected children in Northwest Ethiopia; multi setting historical follow-up study

BACKGROUND

Even though treatment failure is higher among TB and HIV infected children in a resource-limited setting, there is no prior evidence in general and in the study area in particular. Hence, this study was aimed at determining the half-life time prediction of developing first-line antiretroviral treatment failure and its risk factors among TB and HIV co-infected children.

METHODS

A historical follow-up study was employed among 239 TB and HIV co-infected children from January 2010-December 2020. The data was entered into Epi data version 4.2.2 and exported to STATA 14.0 Software for analysis. The Kaplan-Meier plot was used to estimate the half-life time to develop treatment failure. The required assumption was fulfilled for each predictor variable. Additionally, those variables having a p-value ≤0.25 in the bivariable analysis were fitted into a multivariable Cox-proportional hazards regression model. P-value, < 0.05 was used to declare a significant association.

RESULTS

A total of 239 TB and HIV co-infected children were involved in this study. The overall half-life time to develop first treatment failure was found to be 101 months, with a total of 1027.8 years' follow-up period. The incidence rate and proportion of developing first-line treatment failure were 5.5 per 100 PPY (Person-Year) [CI (confidence interval): 3.7, 6.9] 100 PPY and 23.8% (CI; 18.8, 29.7) respectively. Factors such as hemoglobin 10 mg/dl [AHR (Adjusted Hazard Ratio): 3.2 (95% CI: 1.30, 7.73), severe acute malnutrition [AHR: 3.8 (95% CI: 1.51, 79.65), World Health Organization stage IV [AHR: 2.4 (95% CI: 1.15, 4.93)], and cotrimoxazole prophylaxis non user [AHR: 2.3 (95% CI: 1.14, 4.47)] were found to be a risk factor to develop treatment failure.

CONCLUSION

In this study, the half-life time to develop first-line treatment failure was found to be very low. In addition, the incidence was found to be very high. The presence of hemoglobin 10 mg/dl, severe acute malnutrition, World Health Organization stage, and non-use of cotrimoxazole prophylaxis were discovered to be risk factors for treatment failure. Further prospective cohort and qualitative studies should be conducted to improve the quality of care in paediatric ART clinics to reduce the incidence or burden of first line treatment failure among TB and HIV co-infected children.

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.

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.

Survival status and predictors of mortality among HIV-positive children initiated antiretroviral therapy in Bahir Dar town public health facilities Amhara region, Ethiopia, 2020

BACKGROUND

Although there is a presence of governmental and non-governmental organizations running to provide quality HIV care services to reduce HIV-related mortality, there is rapid disease progression and death among children in developing countries including Ethiopia. Thus, this study was aimed to assess the mortality predictors of children living with HIV at Bahir Dar town public health facilities.

METHOD

A facility-based retrospective follow-up study was conducted among 588 children who were enrolled in the HIV care clinic from 1 September 2010 to 30 August 2019. Data were entered into the Epi-Data entry 3.1 and then exported to STATA version 14 for analysis. Multiple imputation models were employed to handle missing data using the multivariate imputation Chained Equations technique. The Kaplan-Meier survival curve and log-rank test were used to estimate and compare the survival time of categorical variables.

RESULT

About 27 (4.6%) (95% confidence interval: 2.9-6.5) deaths were observed from the 30,062.3 person-months follow-up period, and the overall incidence density rate of 0.9 per 1000 child-months (95% confidence interval: 0.6-1.3). Advanced WHO clinical stage (adjusted hazard ratio = 3.18; 95% confidence interval: 1.07-9.43), hemoglobin level less than 8 g/dL (adjusted hazard ratio = 3.54; 95% confidence interval: 1.27-8.85), children having a weight for age of <-2z (adjusted hazard ratio = 2.81; 95% confidence interval: 1.19-6.6), children with poor adherence (adjusted hazard ratio = 3.91; 95% confidence interval: 1.41-10.8), and starting the treatment beyond 1 week of being eligible (adjusted hazard ratio = 3.22; 95% confidence interval: 1.21-8.53) were predictors of HIV-related mortality among children initiated antiretroviral therapy.

CONCLUSION

The hazard of mortality was higher among HIV-infected children in the early period of initiation. Enhancing antiretroviral therapy drug adherence, monitoring Hgb level, and timely initiation of antiretroviral therapy reduce HIV-related mortality.

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.

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.

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.

The Disclosure Dilemma: Willingness to Disclose a Positive HIV Status Among Individuals Preparing for HIV Testing During Antenatal Care in Tanzania

HIV status disclosure can reduce transmission risks and improve care engagement. Individuals may have strong feelings about HIV disclosure even prior to diagnosis. We assessed willingness to disclose a positive HIV status among pregnant women and their male partners awaiting routine HIV testing during antenatal care in Tanzania (n = 939). Logistic regression models were used to examine factors associated with willingness to disclose to one's inner circle (partner/family member) and outer circle (friend/neighbor) in the event of an HIV diagnosis. Almost all (93%) were willing to disclose to at least one person; participants were more willing to disclose to their inner circle (91%) vs outer circle (52%). Individuals with some form of employment, more stigmatizing attitudes of social distancing of PLWH, greater anticipated HIV stigma, more perceived social support, and prior contact with someone living with HIV were more likely to disclose to their inner circles. Individuals who were older, male, and who had higher levels of perceived social support were more willing to disclose to their outer circle. These findings increase the understanding of the intra- and interpersonal factors that influence HIV disclosure decisions. Tailored pre- and post- HIV test counseling are needed to facilitate social support and overcome barriers to disclosure if they test positive for HIV.

Malaria and intestinal parasite co-infection and its association with anaemia among people living with HIV in Buea, Southwest Cameroon: A community-based retrospective cohort study

Background

Both malaria and intestinal parasites are endemic in Cameroon, and their co-infection can be of great impact on anaemia among people living with HIV (PLWH). This community-based retrospective cohort study determined the prevalence and association of infections with anaemia in PLWH and HIV-negative individuals in Buea, Cameroon from March to August 2019.

Methods

The study population comprised of 190 PLWH and 216 consenting HIV-negative individuals from the Buea community. Participants were examined clinically, the collected blood sample was used for malaria parasite (MP) detection, HIV diagnosis and haemoglobin (Hb) measurement while stool samples were examined for the detection of intestinal parasites (IPs). Proportions were compared using Pearson’s Chi-square test and association of anaemia with independent variables was evaluated using logistic regression analysis.

Results

Out of the 406 participants, MP, IPs and MP/IP co-infection prevalences were 15.5%, 13.0% and 3.0% respectively. PLWH had a higher prevalence of MP (16.3%, P = 0.17), IPs (23.7%, P ˂ 0.001) and MP/IPs co-infection (3.7%, P = 0.04) when compared with HIV-negative participants. Similarly, PLWH had significantly lower mean haemoglobin value (11.10 ± 1.54 g/dL) than their HIV-negative counterparts (12.45 ± 2.06 g/dL). Also, PLWH co-infected with MP and IPs were observed to have a significantly lower mean haemoglobin value (10.6 ± 1.21 g/dL). PLWH had a significantly (P ˂ 0.001) higher prevalence of mild (56.8%), moderate (18.4%) and severe (1.6%) anaemia when compared with HIV-negative counterparts. The significant risk factors associated with anaemia included being febrile (P = 0.03), MP-infected only (P = 0.001), HIV-infected only (P < 0.001), having dual (P < 0.001) or triple-infections (P = 0.03).

Conclusion

Malaria and intestinal parasites remain public health concerns among PLWH and anaemia as a serious haematological abnormality gets exacerbated even with the viral load suppression. Hence, routine medical check-ups among PLWH are recommended.

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

Background

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

Method

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

Result

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

Conclusion

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