The Impact of Undernutrition and Anemia on HIV-Related Mortality Among Children on ART in Sub-Saharan Africa: A Systematic Review and Meta-Analysis.

Although there have been significant advancements in providing HIV-infected children with access to antiretroviral therapy (ART), the mortality rates have remained unacceptably high. Inadequate nutrient intake or absorption is a widespread problem in several African nations, resulting in undernutrition and anemia. However, the pooled effect of malnutrition and anemia on HIV-related death related to children receiving ART was not investigated in sub-Saharan Africa. We searched multiple electronic databases (PubMed/MEDLINE, Embase, CINAHL, and Web of Science) for observational studies published between January 1, 2010, and April 24, 2024 that reported the risk factors or effects of undernutrition and, anemia on HIV-related mortality among children. Study selection, data extraction, and quality evaluation were carried out separately by two reviewers. A meta-analysis was conducted using random effect models. The review included 27 studies with a combined total of 61,796 study participants. The study findings showed that severe wasting (HR: 2.49; 95% CI: 1.87-3.30), being underweight (HR: 2.11; 95% CI: 1.64-2.72), and Anemia (HR: 2.58; 95% CI: 2.08-3.19) were highly linked to HIV-related death among children. The risk of death due to anemia was greater among children under the age of 5 years than older children. Undernutrition and anemia in sub-Saharan African children increased the risk of HIV-related death. The impact of malnutrition and anemia among under 5 years old children with HIV/AIDS was more pronounced, suggesting that these conditions at this early age can have more serious consequences for a child's survival. The importance of combining nutrition with HIV treatment programs in sub-Saharan African countries is crucial.

Hepatitis A Seroprevalence Among HIV-Exposed and Unexposed Pediatric Populations in South Africa

Background: There is limited evidence comparing hepatitis A seroprevalence among HIV-exposed uninfected (HEU), HIV-infected (HIV), and unexposed uninfected (HUU) children. This compromises rational vaccine decision-making. Methods: This study comprised a retrospective health facility-based population of children aged 1 month–12 years. Archival sera were tested for markers of acute (anti-HAV IgM) or past (total anti-HAV) HAV infection. Subgroup analysis was conducted based on perinatal HIV exposure or infection status. Results: Among 513 children, the median age was 10 (IQR: 4–25) months. The median maternal age was 29 (IQR: 25–34) years. An anti-HAV seropositivity of 95.1% (117/122 [95% CI 90.2–98.4]) was found among those ≤6 months of age, indicative of the rate of transplacental antibody transfer. Among 1–12-year-olds, hepatitis A seroprevalence was 19.3% (37/192 [95% CI 14.1–25.7]), while 1.1% (2/188 [95% CI 0.12–2.76]) had evidence of acute infection. Compared to HIV-exposed subgroups (HIV = 60%, 6/10 [95% CI 27.4–86.3] and HEU = 45%, 9/20 [95% CI 23.8–68]), hepatitis A seroprevalence among HUU children was low (29.2%, 47/161 [95% CI 22.4–37.0]). Conclusions: Natural immunity among HIV-exposed and unexposed children in South Africa is insufficient to protect against severe liver complications associated with HAV infection later in adulthood.

Associations of linear growth with body composition of perinatally HIV-infected African adolescents.

The prevalence of poor linear growth among African children with perinatally acquired HIV remains high. There is concern that poor linear growth may to lead to later total and central fat deposition and associated non-communicable disease risks. We investigated associations between height-for-age Z score (HAZ) and total and regional fat and lean mass measured by dual-energy X-ray absorptiometry, expressed as internal population Z scores, among 839 Zimbabwean and Zambian perinatally HIV-infected male and female adolescents aged 11-19 years. Stunting (HAZ < -2) was present in 37 % of males and 23 % of females. HAZ was strongly positively associated with total, trunk, arm and leg fat mass and lean mass Z scores, in analyses controlling for pubertal stage, socio-economic status and HIV viral load. Associations of linear growth with lean mass were stronger than those with fat outcomes; associations with total and regional fat were similar, indicating no preferential central fat deposition. There was no evidence that age of starting antiretroviral therapy was associated with HAZ or body composition. Non-suppressed HIV viral load was associated with lower lean but not fat mass. The results do not support the hypothesis that poor linear growth or stunting are risk factors for later total or central fat deposition. Rather, increased linear growth primarily benefits lean mass but also promotes fat mass, both consistent with larger body size. Nutritional and/or HIV infection control programmes need to address the high prevalence of stunting among perinatally HIV-infected children in order to mitigate constraints on the accretion of lean and fat mass.

Population-Specific Predictors of Immunologic Reconstitution Following Initiation of Combined Antiretroviral Therapy in Children: A Retrospective Observational Study from a 15-Year Cohort of HIV-Positive Children and Adolescents in Eritrea.

In the landscape of HIV treatment, combined antiretroviral therapy (cART) is a cornerstone in managing viral loads and boosting CD4+ T-cell counts. Nevertheless, disparities in treatment outcomes remain persistent, and a subset of children fail to achieve adequate immunologic reconstitution (IR). This study aims to investigate the demographic and clinical factors associated with inadequate IR in HIV-infected children in Eritrea. A retrospective observational study was conducted on 822 children followed at Orotta National Pediatric Referral Hospital between 2005 and 2020. Two distinct analyses were performed, with univariate and multivariate logistic regression models employed to investigate risk factors contributing to inadequate immunologic reconstitution (IR) at the study endpoints of 6- and 12-months post-cART initiation. From the initial cohort of 822 patients [53.4% were males, cohort median age at cART initiation was 78 (IQR: 48-101) months and median absolute CD4 count 270 (151-441) cells/µL]. Two separate analyses were conducted on two cohort subsets with complete data, including 456 children at the 6-month mark and 495 children at 12 months of follow-up. Following 6 months on cART, Immunologic reconstitution was achieved in 87.8% (95% CI: 84.3-91.2) and increased to 90.4% (95% CI: 87.3-93.5) after 12 months of treatment. Independent predictors of inadequate IR after 6 months of cART were higher baseline absolute CD4 counts (aOR = 1.003, (95% CI: 1.002-1.005); p-value <0.001) and NNRTI (EFV: aOR = 3.9, (95% CI: 1.3-11.9); p-value = 0.01). Meanwhile, gender (females: aOR = 0.3, (95% CI: 0.1-0.9, p-value = 0.03) and higher baseline absolute CD4 counts (aOR = 1.003, (95% CI: 1.002-1.005); p-value < 0.001) were independent risk factors of inadequate IR after 12 months of treatment. The study underscores the interplay of baseline CD4 count, gender, and regimen choice in shaping the effectiveness of cART in children. Lower baseline absolute CD4 count was associated with IR after starting cART. Notably, children on EFV had a higher likelihood of inadequate IR after 6 months, and male children were more prone to insufficient IR at 12 months. Targeting these population-specific factors may be pivotal in advancing gender-responsive therapeutic strategies and improving health outcomes for HIV-infected children in sub-optimal clinical settings and resource-constrained environments.

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

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

Torque teno virus: a potential marker of immune reconstitution in youths with vertically acquired HIV

Torque teno virus (TTV) viral load (VL), a component of the human virome, increases during immune suppression or dysregulation. This study aimed to explore TTV VL in youths living with vertically acquired HIV (YWVH) and its potential as an immunovirological marker. We performed an observational, retrospective study involving YWVH under antiretroviral treatment (ART) from the Spanish Cohort of HIV-infected children, adolescents, and vertically HIV-infected patients transferred to Adult Units (CoRISpe-FARO), compared to HIV-negative healthy donors (HD). Plasma TTV VL was assessed by qPCR. T-cell phenotype was analysed on cryopreserved peripheral blood mononuclear cells by flow cytometry. Correlations with baseline CD4 and CD8 and long-term virological evolution were examined. A total of 57 YWVH were compared with 23 HD. YWVH had a median CD4 T-cells of 736 cells/mm3 [IQR: 574–906], a median of 17 years [IQR: 14–20.5] since ART initiation, and 65 months [IQR: 39–116] under HIV-RNA virological control. TTV VL was higher among YWVH and in males compared with females (p < 0.05). Among YWVH, TTV VL correlated with CD4 and CD8 counts and the CD4/CD8 ratio (p = 0.002; r = − 0.39, p = 0.037; r = 0.277, p = 0.005; r = − 0.37 respectively). TTV VL correlated with activation expression markers (HLA-DR+/CD38+) on CD4 (p = 0.007, r = 0.39) and the soluble proinflammatory cytokine IL-6 (p = 0.006, r = 0.38).

Incidence and predictors of opportunistic infections among HIV-infected children on antiretroviral therapy at public health facilities of Southwest Ethiopia People Regional State, 2023: a multicenter retrospective follow-up study

BackgroundOpportunistic infections (OIs) pose a significant threat to children infected with HIV. Despite advancements in antiretroviral therapy (ART), these infections continue to be a public health concern. However, there is limited evidence regarding the incidence and predictors of OIs among HIV-infected children in Ethiopia, particularly in the study area. Therefore, the objective of this study was to assess the incidence and predictors of OIs among HIV-infected children on ART at public health facilities of Southwest Ethiopia People Regional State.MethodsThe study employed an institution-based retrospective cohort design, conducted from July 1, 2018 to July 31, 2023, among HIV-infected children aged less than 15 years. Data were extracted using the national ART intake and follow-up forms. KoboCollect version 2023.2.4 and STATA version 14.0 were used for data collection and analysis, respectively. The Kaplan-Meier survival curve was used to estimate the probability of OI-free survival time. Variables with P-value < 0.25 in the bivariable Cox proportional hazard model were selected as candidates. In multivariable analysis, P-value < 0.05 and adjusted hazard ratio (AHR) with 95% confidence interval (CI) were used to declare statistically significant predictors.ResultsOf the total 409 HIV infected children, 122(29.8%) developed at least one OI, contributing to 954.95 person-years of risk. The overall incidence rate was 12.8 (95% CI: 10.7, 15.2) per 100 person-years. The OI-free survival probability at the end of the follow-up period was 0.277(95% CI: 0.139, 0.434). The commonest OI was pulmonary tuberculosis, 30.33% (95% CI: 22.7, 39.2). Non-disclosing HIV status (AHR: 2.56, 95% CI: 1.42, 4.63), children aged 10–14 years (AHR: 2.34, 95% CI: 1.10, 4.95), no history of prevention of mother-to-child transmission of HIV (AHR: 2.33, 95% CI: 1.48, 3.66), hemoglobin level < 10 mg/dL (AHR: 2.26, 95% CI: 1.37, 3.75), fair or poor adherence to ART (AHR: 1.74, 95% CI: 1.09, 2.79), and having past history of OIs (AHR: 1.61, 95% CI: 1.03, 2.55) were statistically significant predictors of OIs.Conclusion and recommendationsThe incidence of OIs was high in the study area. Hence, health facilities need to regularly monitor hemoglobin, enhance ART adherence, provide OI prophylaxis for at-risk children, reinforce PMTCT programs for early OI detection and management, and encourage timely and age-appropriate HIV status disclosure. Caregivers of HIV-infected children are also required to oversee and assist their children in adhering to the ART.

Asymptomatic malaria parasitaemia and virological non-suppression among children living with HIV in a low transmission area in Accra, Ghana: a cross-sectional study

BackgroundHuman Immunodeficiency Virus (HIV) and malaria are two major diseases in sub-Saharan Africa. Co-infection can significantly impact the clinical outcomes of both conditions. We assessed the proportion of HIV-infected children at Korle Bu Teaching Hospital (KBTH) and Princess Marie Louise Hospital (PML) with malaria parasites. The association between asymptomatic malaria parasitaemia and virological non-suppression was also determined in these children.MethodsThis cross-sectional study of 277 asymptomatic malaria in children receiving care at paediatric HIV clinics at KBTH and PML was conducted from September to November 2022. Patients who had been on antiretroviral therapy (ART) for at least six months were eligible to participate. Structured questionnaires were used to collect socio-demographic information, malaria prevention behaviors, and ART-related data using in-person interviews. Microscopy and PCR were used to screen for malaria, and GeneXpert was used to determine viral load. To examine the determinants of malaria PCR positivity and virological non-suppression, chi-square tests and logistic regression were performed.ResultsThe median age of the participants was 9 years (range: 6–12 years). Males comprised 158 (57%) of the study population. We detected 10 (3.6%) and 21 (7.6%) malaria cases by microscopy and PCR, respectively. Virological non-suppression (VL > 1000 copies/ml) was observed in 82 (29.6%) of the 277 participants. Among the suppressed individuals, 62 (22.4%) exhibited low-level viraemia (VL level 40-1000 copies/ml) and 133 (48%) had undetectable viral load levels. No factors were associated with the presence of malaria PCR positivity carriage. Poor adherence to ART was associated with a five-fold increase in the risk of viral load non-suppression (AOR = 4.89 [CI = 2.00-11.98], p = 0.001).ConclusionThe proportion of children living with HIV with asymptomatic malaria parasitaemia was low. Approximately one-third of the study population had virological non-suppression. The interaction between malaria parasitemia and viral replication may not be the main cause for virological non-suppression in this low transmission area.

Gallbladder Burkitt's Lymphoma: A Literature Review Including a Case Report in a Child Living with HIV.

Malignant lymphoma is an unusual form of gallbladder neoplasm. Almost all these tumors are diffuse large B-cell lymphomas or mucosa-associated lymphoid tissue-type lymphomas. Herein, we present a literature review of gallbladder Burkitt's lymphoma (BL) cases that includes also an unpublished case in an HIV-infected child, observed by our center. The patient (a five-year-old black female child) attended the Federal Hospital of Lagoa, Rio de Janeiro, Brazil, underwent cholecystectomy, and the postoperative pathological analysis of the gallbladder revealed a diagnosis of BL (EBV-positive). Also, HIV serology was performed and returned positive. She was transferred to the Martagão Gesteira Institute of Pediatrics and Childcare for oncological treatment, dying from sepsis and disease progression about 18 months later. The patient did not undergo ART/cART. Previous cases of gallbladder BL were herein described and analyzed to characterize the clinicopathological features and possible similarities. BL can occur in the gallbladder both in the context of HIV infection and in the pediatric population. A biopsy is mandatory in cases with suggestive findings of lymphoma, and an early diagnosis can change the course of the disease. Furthermore, the case highlights the importance of an early initiation of ART/cART in people living with HIV (PLWH), especially in children.

Rates of Viral Non-Suppression and Acquired HIV-1 Drug Resistance Emergence among Children during the Sociopolitical Crisis in the Northwest Region of Cameroon: A Call for Improved Monitoring Strategies.

Virological failure (VF) among children remains concerning, with high risks of HIV drug resistance (HIVDR) emergence and increased disease progression. Therefore, monitoring of viral non-suppression and emerging HIVDR is crucial, especially in the frame of sociopolitical unrest. The study sought to determine the prevalence of VF and evaluate the acquired HIVDR and viral genetic diversity among children in the northwest region of Cameroon during the ongoing sociopolitical crisis. A cross-sectional facility-based study was conducted among HIV-infected children aged ≤18 years, receiving antiretroviral therapy (ART) in urban and rural settings of Northwest Cameroon, from November 2017 through May 2018. Viral load (VL) was done using the Abbott m2000RealTime. Unsuppressed VL was defined as viral load ≥1,000 copies/ml. HIVDR testing was performed by sequencing of HIV-1 protease-reverse transcriptase at the Chantal Biya International Reference Center (CIRCB) using an in-house protocol. Drug resistance mutations (DRM) were interpreted using Stanford HIVdbv8.5 and phylogeny using MEGAv.6. Data were compared between urban and rural areas with p<0.05 considered statistically significant. A total of 363 children were recruited, average age of 12 years (urban) and 8 years (rural). VL coverage was 100% in the urban setting and 77% in the rural setting. Overall, VF was 40.5% (39% [130/332] in the urban setting and 41% (13/31) in the rural setting; p=0.45). Overall, viral undetectability (defined as VL<40 copies/ml) was 45.5% (46% (urban) and 45% (rural); p=0.47). Among those experiencing confirmed virological failure and who were successfully sequenced (n=35), the overall rate of HIVDR was 100% (35/35). By drug class, HIVDR rates were 97.1% (34/35) for non-nucleoside reverse transcriptase inhibitors (NNRTIs), 97.1% (34/35) for NRTIs and 17.1% (6/35) for protease inhibitors (22.7% (5/22) in the urban setting and 7.7% [1/13] in the rural setting). CRF02_AG was the most prevalent viral clade (75%), followed by other recombinants (09_cpx, 11_cpx, 13_cpx, 22_01A1, 37_cpx) and pure subtypes (A1, F2, G, H). In this population of children and adolescents living with HIV in a context of socio-political instability in the North-West region of Cameroon, rates of viral non-suppression are high, and accompanied by HIVDR selection. Our suggests the need for a more differentiated care of these CAHIV, especially those in these regions faced with significant socio-economic and health impacts due to the ongoing crisis.

Treatment failure among Sub-Sahara African children living with HIV: a systematic review and meta-analysis

BackgroundAntiretroviral treatment failure is a global issue, particularly in developing countries such as Sub-Saharan Africa. Prior research findings were highly variable and inconsistent across areas. As a result, the goal of this systematic review and meta-analysis was to determine the pooled prevalence of treatment failure among children receiving antiretroviral medication in Sub-Saharan Africa.MethodsTo find qualifying papers, we searched databases (such as PubMed, Google Scholar, African Journals Online, Scopus, and the Cochrane Library). The data were retrieved using Microsoft Excel and exported to STATA Version 14 for analysis. To check for publication bias, we employed Egger and Begg’s regression tests. A random-effects model was used to assess the pooled prevalence of treatment failure due to high levels of variability.ResultsFollowing the removal of duplicated articles and quality screening, a total of 33 primary articles were determined to be appropriate for inclusion in the final analysis for this study. Overall, the pooled prevalence of treatment failure among HIV-infected children was 25.86% (95% CI: 21.46, 30.26). There is great variety across the included studies, with the majority of them being conducted in Ethiopia. Cameroon had the greatest pooled prevalence of treatment failure among HIV-infected children, at 39.41% (95% CI: 21.54, 57.28), while Ethiopia had the lowest, at 13.77% (95% CI: 10.08, 17.47).ConclusionsThe pooled estimate prevalence of treatment failure among HIV-infected children in Sub-Saharan Africa was high. The implementation of national and international policies and strategies on ART clinic care services should be given special focus in order to reduce treatment failure in children living with HIV/AIDS.Trial registrationThe protocol has been registered in the PROSPERO database under the registration number CRD-429011.

Incidence of loss to follow-up and its predictors among HIV-infected under-five children after initiation of antiretroviral therapy in West Amhara Comprehensive Specialized Referral Hospitals, Northwest Ethiopia: a multicenter retrospective follow-up study

BackgroundLoss to follow-up (LTFU) among under-five children from HIV care profoundly affects the treatment outcomes of this vulnerable population. It is a major factor that negatively affects the benefits of antiretroviral therapy (ART). Current information about LTFU among HIV-positive under-five children on ART is essential for effective treatments. To far, nevertheless, limited research has been done in Ethiopia to address this issue. Thus, this study aimed to assess the incidence and predictors of LTFU among HIV-infected under-five children receiving ART in West Amhara Comprehensive Specialized Referral Hospitals.MethodsA multicenter institution-based retrospective follow-up study was conducted among 435 HIV-infected under-five children on ART selected by simple random sampling from January 1, 2010 to December 31, 2019, and data were collected between December 1, 2021, and January 31, 2022. A standardized data extraction tool adapted from the ART entry and follow-up forms was used. The event of interest for this study was LTFU, whereas the absence of LTFU was censored. Before being transferred to STATA version 14 for analysis, the data were entered into Epi-Data version 3.1. The Kaplan‒Meier curve was used to estimate an individual's survival-free probability at each specific point in time. The Cox proportional hazards model was used to identify predictors of LTFU.ResultsAmong the 420 records included in the final analysis, 30 (7.14%) of the individuals were LTFUs. The incidence rate of LTFU was 3.4 per 1000 person-months of observation (95% CI: 2.43–4.87). The survival probabilities of children after 12, 24, 36, and 48 months were 0.97, 0.92, 0.88, and 0.77, respectively. The independent predictors of LTFU were HIV infection in under-five children who lived in rural areas (AHR = 3.64; 95% CI: 1.41, 9.37), poor adherence to ART (AHR = 4.37; 95% CI: 1.59, 12.02), not receiving cotrimoxazole preventive therapy (AHR = 3.75; 95% CI: 1.39, 10.08), not receiving isoniazid prophylaxis (AHR = 3.4; 95% CI: 1.29, 9.01), and having a severe WHO clinical stage (AHR = 5.43; 95% CI: 1.38, 11.43).Conclusion and recommendationThe incidence of loss to follow-up was high, especially in the first two years after ART initiation. The risk of LTFU was greater for those who were rural residents, had poor adherence, lacked cotrimoxazole preventive therapy, not given isoniazid prophylaxis, and presented with WHO clinical stages III and IV. Therefore, clinicians should emphasize for cotrimoxazole preventive therapy and isoniazid prophylaxis, for those living in rural areas, who present with poor adherence and WHO clinical stages III and IV.

Incidence and predictors of virological failure among HIV infected children and adolescents receiving second-line antiretroviral therapy in Uganda, a retrospective study

BackgroundIn Uganda, 20% (19,073/94,579) of children and adolescents (0-19 years) living with HIV (CALHIV) were receiving second-line antiretroviral therapy (ART) by the end of March 2020. Data on incidence and predictors of virological failure among these CALHIV on second-line ART is limited. Lack of this information and limited access to HIV drug resistance testing prevents early identification of CALHIV at risk of virological failure on second-line ART. The aim of this study was to determine the incidence and predictors of virological failure among CALHIV on second-line ART in Uganda.MethodologyThis was a retrospective cohort study of all CALHIV aged 0-19 years who were switched to second-line ART regimen between June 2010 and June 2019 at the Baylor Uganda Centre of Excellence clinic. Data was analysed using STATA 14. Cumulative incidence curves were used to assess incidence of virological failure. Factors associated with virological failure were identified using sub-distributional hazard regression analysis for competing risks considering death, transfer out and loss to follow-up as competing risks.ResultsOf 1104 CALHIV, 53% were male. At switch to Protease Inhibitor (PI) based second-line ART, majority (47.7%) were aged 5 – 9 years,56.2% had no/mild immune suppression for age while 77% had viral load copies < 100,000 copies/mL. The incidence of virological failure on second-line ART regimen among CALHIV was 3.9 per 100 person-years (PY) with a 10-year cumulative incidence rate of 32%. Factors significantly associated with virological failure were age 10 – 19 years (HR 3.2, 95% 1.6 – 6.2, p < 0.01) and HIV viral load count > 100,000 copies/mL (HR 2.2, 95% CI 1.5 – 3.1), p < 0.01) prior to second-line ART switch.ConclusionTreatment outcomes for children and adolescents on second-line ART are favourable with one third of them developing virological failure at 10 years of follow up. Adolescent age group and high HIV viral load at the start of second-line ART were significantly associated with virological failure on second-line ART. There is need to determine optimal strategies to improve ART treatment outcomes among adolescents with high viral load counts at second-line ART switch.

Effect of highly-active antiretroviral therapy on neuroendocrine regulation of immunogenesis in HIV-infected children

Comparative assay has been made against the parameters of the immune and endocrine systems in 84 HIV-infected children born from HIV-infected mothers. One group of analyzed children (36 patients) did not receive highly-active antiretroviral therapy. Another group (48 patients) received different variants of highly-active antiretroviral therapy. Children aged from 1 to 182 months were examined. Venous blood samples taken from young patients were used to determine leukocyte blood composition considering the relative (%) and absolute number of blood cell counts. Hormone concentration was determined concurrently. CD-molecule expression by mononuclear cells was registered using flow cytofluorimeter. Plasma viral load in HIV-infected children was quantitatively detected with RT-PCR. Statistically significant lowering in the levels of free thyroxin, cortisol and progesterone was observed in children against a background of highly-active antiretroviral therapy as compared to those without HAART use. Correlation assay between the hormone level and the immunological parameters in children not receiving the antiretroviral preparations revealed marked positive correlations among the somatotropic hormone level and CD3+, CD4+ and CD8+ absolute numbers. Similar positive correlation with absolute T-subset number was found against free T4. The progesterone level also positively correlated with relative CD3+ and CD8+ numbers and showed negative correlation with absolute CD4+ amount. There is another positive correlation with relative T-subset number against the dehydroepiandrosterone level in the group of children without antiretroviral preparation therapy. As for HIV-infected group of children, against a background of highly-active antiretroviral therapy, the results of correlation assay between the hormone concentrations and cell parameters were found to significantly vary. There were observed positive correlations between the levels of cortisol and CD3+ (%), cortisol and CD8+ (%), estradiol and CD4/CD8, progesterone and absolute CD8+ number. As with children not receiving the antiretroviral preparations marked positive relation was revealed between the concentration of free thyroxin and absolute values of CD4+. Negative correlations were recorded between the estradiol level and the relative CD3+ numbers. Against a background of applying the antiretroviral preparations the correlation assay conducted between the viral RNA concentration (lg of copy number of mRNA/ml) and analyzed endocrinological parameters was found to have marked positive correlation with HIV concentration demonstrated by estradiol and testosterone. During the antiretroviral therapy, however, the negative correlation between the thyrotropin level and lg concentration of viral RNA was observed. Analytical results of correlation among the viral RNA concentration (lg copy number of mRNA/ml) and analyzed immunological parameters in this group of children evidence for specific ‘normalization’ due to highly-active antiretroviral therapy as the only positive correlation with virus concentration was detected for CD4+T subsets. Therefore, the alteration in endocrine system state in children born from HIV-infected mothers could be of great significance while monitoring the systemic regulation of the immunogenesis.

Incidence of mother-to-child transmission of HIV and predictors of positivity among HIV exposed infants in South Gondar public hospitals, Northwest Ethiopia: competing risk regression model

BackgroundThe principal route of HIV infection in children is vertical transmission. Thus, this study aimed to assess the incidence of mother-to-child transmission of HIV and predictors of positivity among HIV-exposed infants.MethodInstitutions-based retrospective follow-up study was conducted in South Gondar Public hospitals, Northwest Ethiopia from December 2019 to November 2021. The data were taken from PMTCT logbooks and patient medical records, with death being the competing event. Data were entered in to Epi info version 7 and exported to STATA version 14 for final analysis. Both bivariable and multiple variable proportional subdistribution hazard analysis were conducted to identify predictors. P-value < 0.05 was level of significance.ResultA total of 469 exposed infant mother pairs records were included. The cumulative incidence rate at the end of the study period was 5.2 per 1000 person months (5.2; 95% CI: 3.4-8.0).Infants’ absence of ARV prophylaxis at birth (aSHR = 3.7; 95% CI: 1.33–10.48), Mothers with no PMTCT intervention (aSHR = 5.1; 95% CI: 1.83–14.03), home delivery (aSHR = 4.1; 95%CI: 1.46–11.63) and maternal disclosure of HIV status to partner/families (aSHR = 2.9; 95% CI: 1.06–7.78) were predictors of HIV positivity.ConclusionThe study found that Infants’ absence of ARV prophylaxis at birth, mothers without PMTCT intervention, home delivery and mothers who were not disclosing their HIV status to families were predictors of HIV positivity.

Experience of practical use of enterosorbents in the treatment of HIV-infected children with diarrhea syndrome

Despite advances in antiretroviral therapy (ART), diarrhea is common among people living with HIV (PLHIV) and negatively impacts quality of life. Although diarrheal diseases caused by opportunistic infections have decreased in the ART era, the overall prevalence of diarrhea remains unchanged, estimated at 28% to 60% of PLHIV.The aim of the study: to conduct a comparative assessment of the clinical efficacy of enterosorbents in the treatment of diarrheal syndrome in children with HIV infection.Materials and methods. The study material included 80 HIV-infected children who experienced acute infectious diarrhea aged 5 to 14 years. The main group included 40 children who received enterosgel, 2 times 1 tablespoon included in the traditional treatment regimen, and the control group included 40 children who received the drug lactofiltrum against the background of traditional therapy, 1 tablet 3 times a day. The duration of treatment was 10 days.Results and discussion. During the treatment of acute diarrhea in children with HIV infection with Enterosgel, a significant decrease in the daily amount and in the duration of diarrhea was observed, which leads to a noticeable loss of signs of dehydration (P&lt;0.05). Elimination of acute diarrhea in children with HIV infection may also have eliminated the underlying intoxication syndrome due to the underlying and burning disease, which may lead to a reduction in health care costs and socioeconomic burden.Conclusion. During the treatment of acute diarrhea in children with HIV infection with Enterosgel, a decrease in the daily amount and in the duration of diarrhea is reliably observed, which leads to a significant disappearance of signs of dehydration (р&lt;0.05).

Predictors for the incidence of pneumonia among HIV-infected children on antiretroviral therapy in Amhara Regional State Comprehensive Specialized Hospitals, Ethiopia: a multicenter retrospective follow-up study

BackgroundHuman Immune deficiency Virus (HIV) infected children are at higher risk of developing pneumonia. Particularly, in the early phase of HIV infection, the risk of acquiring pneumonia is high, and it remains a major public health problem even after the test and treatment strategy. There is no clear evidence of the overall incidence of pneumonia among HIV-infected children in Amhara region. Aimed to assess the incidence of pneumonia and its predictors among HIV-infected children receiving Antiretroviral therapy in Amhara Region Comprehensive Specialized Hospitals, 2022.MethodsA multicenter retrospective follow-up study was conducted from June 10, 2014, to February 28, 2022, among 430 HIV-positive children receiving antiretroviral therapy. A simple random sampling technique was used. The data was taken from the national antiretroviral intake and follow-up forms. The data were collected via the KoBo toolbox and analyzed using Stata version 17. The Kaplan–Meier curve and log-rank test were employed. Bivariable and multivariable Cox regression was carried out to identify predictors of pneumonia and a P-value < 0.05 was considered significant in to multivariable analysis.ResultsA total of 407 children with a record completeness rate of 94.7% were analyzed in the study. The incidence rate of pneumonia was 4.55 (95% CI; 3.5, 5.92) per 100 person-years observation. The mean survival time was 77.67 months and the total times at risk during follow-up period were yielding 1229.33 person-year observations. Having CD4 cell count below threshold [AHR; 2.71 (95% CI: 1.37, 5.35)], WHO stage III and IV [AHR: 2.17 (95% CI: 1.15, 4.08)], ever had fair and poor treatment adherence [AHR: 2.66 (95% CI: 1.45, 4.89)], and not initiated antiretroviral therapy within seven days [AHR: 2.35 (95% CI: 1.15, 4.78)] were the positive predictors for incidence of Pneumonia.ConclusionsIn this study, the incidence of pneumonia was lower than the previous studies. CD4 cells below the threshold, ever had fair and poor adherence to antiretroviral therapy, WHO stage III and IV, and not initiated antiretroviral therapy within seven days were significant predictors. Therefore,, it is crucial to detect baseline assessment and give attention to those identified predictors promptly, and timely initiation of antiretroviral therapy need special attention.

Nutritional status of HIV-infected children at Federal University Teaching Hospital, Owerri, Nigeria: A prospective analysis of rural and urban dwellers.

Malnutrition is a critical concern among children living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), particularly in regions heavily affected by the HIV epidemic, such as sub-Saharan Africa. In 2019, nearly 2.84 million children under 19 years of age were living with HIV globally, with over 90% residing in sub-Saharan Africa. Concurrently, malnutrition remains prevalent in the region, with approximately 49 million children under the age of 5 experiencing stunting and 149 million suffering from wasting in 2018. This burden of malnutrition is exacerbated by factors such as poverty, food insecurity, and HIV/AIDS, which collectively contribute to adverse health outcomes among affected children. The bidirectional relationship between HIV/AIDS and malnutrition is well-established, with HIV infection increasing the risk of malnutrition and malnutrition worsening the progression of HIV/AIDS. Studies have consistently demonstrated higher rates of stunting, underweight, and wasting among HIV-infected children compared to their uninfected counterparts. Moreover, malnutrition significantly impacts the disease progression, morbidity, and mortality of HIV-infected individuals, further underscoring the importance of addressing this issue in pediatric HIV care. A total of 99 HIV-infected children, aged 2 to 16 years, were consecutively recruited from the pediatric infectious disease clinic of the Federal University Teaching Hospital Owerri. Anthropometric measurements, including weight and height, were obtained using a stadiometer (RGZ-160 England). Weight status was categorized as normal, underweight, overweight, or obese, while height status was classified as stunted, normal, or tall stature. The study participants ranged in age from 2 to 16 years. Approximately 20.2% of the children were underweight, and 6.1% were classified as obese. Stunting was observed in 29.3% of the participants. Notably, all forms of malnutrition, including underweight and overweight, were more prevalent among children residing in rural areas. In addition, stunting was more common among rural dwellers. This study highlights the high prevalence of malnutrition among HIV-infected children attending the pediatric infectious disease clinic at the Federal University Teaching Hospital Owerri. The findings underscore the urgent need for targeted nutritional interventions, particularly in rural areas, to improve the health outcomes of HIV-infected children.
