Impact of highly active antiretroviral therapy on hematological indices among HIV-1 infected children at Kenyatta National Hospital-Kenya: retrospective study

Incidence and predictors of common opportunistic infections among children less than 15 years of age on antiretroviral therapy in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Despite significant efforts to enhance access to antiretroviral therapy (ART), opportunistic infections among children on ART remain a major concern in low-income countries, including Ethiopia. Currently, there are no pooled estimates of opportunistic infections incidence among children on ART in Ethiopia. Consequently, this review aimed to determine the pooled incidence and identify the predictors of opportunistic infections among children under 15 years of age on ART, addressing the existing information gap.

METHODS

This systematic review followed the PRISMA guidelines, and relevant studies were obtained from the PubMed, CINAHL, Scopus, EMBASE, and Google Scholar databases. Data analysis for pooled estimates of incidence and predictors of opportunistic infections was conducted via STATA 17 software with random-effects model. Heterogeneity was evaluated via Cochrane's Q-test and the I2 statistic, and publication bias was assessed through funnel plots and Egger's test.

RESULTS

Of the 5,631 studies identified, 20 studies involving 9,196 participants were included in the meta-analysis. The pooled incidence of opportunistic infections among children under 15 years of age on antiretroviral therapy was 5.61 per 100 person-years (95% CI: 4.37-6.86), based on 36,716.4 person-years of observation. Predictors of opportunistic infections included advanced WHO clinical stage (HR 1.45, 95% CI: 1.35-1.55), poor ART adherence (HR 1.49, 95% CI: 1.35-1.63), lack of isoniazid (HR 1.56, 95% CI: 1.40-1.74) and cotrimoxazole preventive therapy (HR 1.56, 95% CI: 1.38-1.66), malnutrition (HR 1.50, 95% CI: 1.34-1.67), and severe immunosuppression (HR 1.39, 95% CI: 1.27-1.51).

CONCLUSION

The incidence of opportunistic infections in this review was high, highlighting the need for intensified efforts to achieve the 2030 target. Moreover, advanced WHO clinical stage, poor adherence, lack of isoniazid and cotrimoxazole preventive therapy, malnutrition, and severe immunosuppression were identified as predictors of opportunistic infections. This suggests that early initiation of ART, regular nutritional assessments, intensive follow-up and monitoring, and a multidisciplinary approach need be prioritized to address the identified predictors.

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.

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.

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.

Time to detection of anaemia and its predictors among women of reproductive-age living with HIV/AIDS initiating ART at public hospitals, Southwest Ethiopia: a multicentre retrospective follow-up study

OBJECTIVE

To assess the time to development of anaemia and its predictors among women of reproductive-age receiving antiretroviral therapy (ART) in public hospitals, Southwest Ethiopia.

DESIGN

Hospital-based retrospective follow-up study SETTING: Mizan-Tepi University Teaching Hospital, and Gebretsadik Shawo General Hospital Southwest Ethiopia.

PARTICIPANTS

A total of 389 records of women living with HIV/AIDS at public hospitals were reviewed using a systematic sampling method. The data were entered using Epi-Data Manager V.4.2 and exported to STATA V.14 for data analysis. A Cox-regression model was used and variables with a p-value of <0.05% and 95% confidence level in multivariable analysis were declared as statistically significant predictors for anaemia.

PRIMARY OUTCOME

Time to development of anaemia and its predictors among women of reproductive-age on ART in public hospitals.

RESULTS

Of 370 records of women of reproductive-age, 203 (54.86%, 95% CI (49.77% to 59.96%)) were anaemic with an incidence rate of 12.07 per 100 person months of observation, and the overall median survival time of 60 months. The total of 2.97%, and 80.26% of women were developed anaemia within the first 6 months and the last 6 months period of follow-up, respectively. Moreover, non-employed women, women with advanced WHO stage, women with baseline opportunistic infections and women who were on ART for long-duration were significantly associated with anaemia among women living with HIV/AIDS.

CONCLUSION

In this study, the incidence rate of anaemia was significantly high. The development of anaemia among women on ART was also increased with increased follow-up time. The risk of anaemia is increased in women living with HIV/AIDS due to advanced baseline WHO staging, presence of OIs at baseline, an increased duration on ART and low occupational status. Therefore, early identification and treatment of opportunistic infections and other coinfections are required to decrease the incidence of anaemia among women living with HIV/AIDS.

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.

Validation of the BD FACSPresto system for the measurement of CD4 T-lymphocytes and hemoglobin concentration in HIV-negative and HIV-positive subjects

This study aimed to compare the performance of the BD FACSPresto system with the conventional standard-of-care technologies for the measurement of absolute CD4 count (AbsCD4), CD4 percentage (CD4%) and total hemoglobin concentration (Hb) in capillary and venous blood samples of HIV-negative and HIV-positive subjects. A total of 1304 participants were included in this prospective cohort study. Both venous and capillary blood samples were analyzed using the BD FACSPresto system and the results were compared against the BD FACSCalibur for enumerating AbsCD4 and CD4% and Sysmex XT-4000i hematology analyzer for determining Hb levels. Method comparison studies were performed using Deming regression and Bland-Altman plots. The Deming regression analyses comparing the accuracy of the BD FACSPresto system with the reference standard technologies demonstrated a significant linear correlation between the AbsCD4, CD4%, and Hb values generated by the two platforms. The 95% CI of the slopes for AbsCD4, CD4%, and Hb levels were 0.94-0.99, 0.99-1.01 and 0.86-0.93, respectively (P < 0.001). Bland-Altman plots for AbsCD4, CD4%, and Hb levels demonstrated close agreement between the BD FACSPresto system and the reference standards for all study participants. The performance and accuracy of BD FACSPresto system was comparable to the reference standard technologies. The BD FACSPresto system can be used interchangeably with BD FACSCalibur platform for CD4 and Sysmex XT-4000i hematology analyzer for Hb concentrations in resource-limited settings thus, improving accessibility to point-of-care testing services.

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.

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.

Histomorphological changes in the pancreas and kidney and histopathological changes in the liver in male Wistar rats on antiretroviral therapy and melatonin treatment

Combination antiretroviral therapy (cART) has shown to cause inflammation, cellular injury and oxidative stress, whereas melatonin has been successful in reducing these effects. The aim of the study was to determine potential morphometric changes caused by cART in combination with melatonin supplementation in human immunodeficiency virus (HIV)-free rats. Tissue samples (N = 40) of the pancreas, liver and kidney from a control (C/ART-/M-), cART group (C/ART + ), melatonin (C/M + ) and experimental group (ART+/M + ) were collected and stained with haematoxylin and eosin (H&E) and evaluated for histopathology. The pancreata were labelled with anti-insulin and anti-glucagon to determine α- and β-cell regions. Kidneys were stained with periodic acid Schiff (PAS) to measure the area, perimeter, diameter and radius of renal corpuscles, glomeruli and proximal convoluted tubules (PCTs). Blood tests were conducted to determine hepatotoxicity. No significant changes in histopathology were seen. Melatonin stimulated pancreatic islet abundance, as the number of islets per mm² was significantly higher in the C/M+ than in the C/ART-/M- and ART+/M+. Parameters of the renal corpuscle, glomeruli, renal space and PCTs were significantly lower in the C/ART+ compared to the other groups, thus cART may have caused tubular dysfunction or cellular damage. A significant increase in serum haemoglobin was observed in the C/ART+ compared to the C/ART-, which showed cART increases serum haemoglobin in the absence of immune deficiency. Serum lipids were significantly decreased in the C/M+ compared to the C/ART-, possibly due to the effect of melatonin on the decrease of lipolysis, decreasing effect on cholesterol absorption and stimulation of lipoprotein lipase (LPL) activity. In conclusion, we have demonstrated that melatonin stimulated α-cell production, increased the number of pancreatic islets and caused a decrease in total lipids, whereas cART increased serum haemoglobin and decreased various parameters of the nephron in an HIV-free rat model, suggestive of tubular dysfunction.

Effect of Zhen Qi Fu Zheng granules on the bone marrow depression model induced by Zidorf

Zidorf is a commonly used drug for the treatment of AIDS, the most common side effects of AZT was bone marrow depression. Therefore, we investigated the effects of Zhen Qi Fu Zheng (AQFZ) granules on the model of bone marrow depression induced by AZT. We showed that the high, medium and low doses of AQFZ granules could increase the number of WBC in the mice model induced by AZT, and the difference was significant (P < 0.01) compared with the model group. Each dose of AQFZ granules can increase the thymus cortex thickness, the number of thymus lymphocytes, spleen nodule size, the number of lymphocytes in the spleen (P < 0.01). The medium dose of AQFZ granules can also significantly improve the number of BMC in the bone marrow depression model (P < 0.01). As well as, the low dose of AQFZ granules can clearly increase the number of nucleated cells in a bone marrow (P < 0.05) and IL-2blood serum. So, AQFZ granules can improve and regulate the hemogram, bone marrow and immune level of bone marrow depression model induced by AZT.

Changes in the haematological parameters of HIV-1 infected children at 6 and 12 months of antiretroviral therapy in a large clinic cohort, North-Central Nigeria

BACKGROUND

Prior to commencing antiretroviral therapy (ART), haematological abnormalities are a common occurrence in individuals diagnosed with human immunodeficiency virus (HIV). In the course of receiving ART, these abnormalities usually improve. We determined the prevalence of haematological abnormalities in children diagnosed with HIV-1 and the changes in haematological parameters that occur after 6 and 12 months of being on ART.

METHODS

A cross-sectional study of HIV-1 infected children aged 2 months to 15 years, between July 2005 and March 2013, at the paediatric HIV clinic of the Jos University Teaching Hospital, Jos. Median values of repeated measures were compared using the Wilcoxon signed-rank sum test.

RESULTS

The prevalence of anaemia, thrombocytopenia and leukopenia among the 941 children studied, prior to ART was 6.4%, 7.0% and 8.6%. Median (IQR) haemoglobin (Hb) levels increased from 10 g/dL (9-11 g/dL) at baseline to 11 g/dL (10-12 g/dL) and 11 g/dL (10-12 g/dL) at 6 and 12 months of ART (P<0.001 and P<0.001), respectively, a 10% increase in both cases. Also, platelet count increased from a median of 327×10³/μL (243-426×10³/μL) at baseline to 333×10³/μL (266-408×10³/μL) at 6 months and 339×10³/μL (267-420×10³/μL) at 12 months, representing a 1.8% and 3.7% increase, respectively. The median total white blood cell count decreased from 7.4×10³/μL (5.3-9.9×10³/μL) at baseline to 5.9×10³/μL (4.6-8.0×10³/μL) and 5.8×10³/μL (4.5-7.5×10³/μL) at 6 and 12 months of ART (P<0.001 and P<0.001), a 20.3% and 21.6% decrease, respectively.

CONCLUSION

During the 12 months of ART, children in our cohort had significant improvements in haematological parameters such as haemoglobin levels and platelet counts, which would suggest an early positive response to 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.

Clinical characteristics of pediatric HIV-1 patients treated with first-line antiretroviral therapy in Vietnam: a nested case-control study

OBJECTIVES

Over the past decades, Vietnam has made great strides in reducing the rate of mortality in HIV-related deaths, due to increased access of antiretroviral therapy (ART); however, given the significantly high level of treatment failure (TF), it is essential to identify markers that describe the failure of ART in HIV-1 infected children.

METHODS

A nested case-control study was conducted with clinical data collected from 101 HIV-infected children [26 TF and 75 treatment success (TS)] at National Hospital of Pediatrics, Vietnam (2008-2012).

RESULTS

The results showed that certain factors including height, weight, vaccination with Hepatitis B, and platelet were significantly different between TF and TS before starting the treatment. In addition, age to start the treatment, CD4 percentage, and opportunistic infection were found to significantly predict treatment outcome most frequently, implying the importance of clinical markers in the treatment response by Cox regression analysis.

CONCLUSIONS

There is an inherent complexity within clinical markers that is challenging to determine HIV-pediatric failure and further research is needed to build a complete picture to guide clinical, evidence-based practice.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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