Kidney Injury in Children Infected with HIV, Followed at the Teaching Hospital of Borgou (Benin)

The history of kidney disease associated with HIV infection dates back to the years of HIV breakthrough. The objective was to study kidney damage in children infected with HIV at the Teaching Hospital of Borgou (Benin) in 2019. This was a cross-sectional, descriptive, analytical, matching-type study carried out from June 1, 2019 to September 30, 2019 at the pediatrics department of Teaching Hospital of Borgou (Benin). The study included HIV-positive children, followed in consultations, and whose parents gave their consent. The biological markers were demon-strated with urine dipstick. Glomerular filtration rate was calculated using the Schwartz test and classified according to stages. The dependent variable was the presence of at least one impairment (biological or functional). Sample size was determined by Schwartz’s method on the basis of one case for two controls. Sociodemographic, clinical, biological, and therapeutic data were collected. Comparisons were made using the Chi-square test or Fisher’s exact test. The identification of associated factors was possible using a multiple logistic regression model at 5% threshold. In total, we included 117 children, including 39 HIV-positive children. The average age was 8 ± 4.81 years and the gender ratio was 1:17. The frequency of kidney damage was 76.5%. Permanent proteinuria and at least two crosses on urine dipstick were present in 20.5%, leukocyturia in 2.6%, and proximal tubular dysfunction in 5.1%. Glomerular hyperfiltration was found in 38.5%, acute kidney injury in 38.5%, and chronic kidney injury in 5.1%. Associated factors were age (P = 0.004), presence of opportunistic infections (P = 0.00), and treatment adherence (P = 0.004). Kidney damage is common in HIV-positive children. Careful follow-up is necessary to avoid complications.

Under-nutrition and associated factors among children on ART in Southern Ethiopia: a facility-based cross-sectional study

BackgroundMalnutrition is very common in HIV-infected individuals. Even though data from different settings are necessary to tackle it, pieces of evidence are limited especially in the case of the nutritional status of HIV-infected children. Hence, this study aims to assess the nutritional status and associated factors among children on antiretroviral therapy.MethodsAn institutional-based cross-sectional study was conducted among 383 HIV-positive children in Southern Ethiopia. Data were collected using an interviewer-administered questionnaire and anthropometry measurement. Data were coded and entered into Epi-Data Version 3.1 and analyzed using SPSS Version 25. Bi-variable and multi-variable binary logistic regression models were used to identify factors associated with nutritional status and variables with p-values <0.05 in multi-variable logistic regression were considered as statistically significant.ResultsThe prevalence of wasting among HIV-positive children in Southern Ethiopiaselected Hospitals was 36.3% (95% CI, 31.6–41.0) while stunting on the same study population was 5.5% (95% CI, 3.4–7.8). Rural residence, lack of maternal education, low CD4 counts (< 500), using an unprotected water source, having a non-biological mother and recurrent oral lesion were significantly associated with wasting. Furthermore, history of hospital admission, recurrent oral lesion, low CD4 counts (< 500), advanced WHO clinical stage were statically associated with stunting with p-value < 0.05.ConclusionThis study found that the prevalence of under-nutrition among HIV-positive children in Ethiopia was significantly high. Therefore, timely identification and monitoring of nutritional problems should be necessary to enhance the effectiveness of ART treatment and to prevent further related complications.

Pharmacokinetics and Drug-Drug Interactions of Abacavir and Lamuvudine Co-administered With Antituberculosis Drugs in HIV-Positive Children Treated for Multidrug-Resistant Tuberculosis.

Given the high prevalence of multidrug-resistant (MDR)-TB in high HIV burden settings, it is important to identify potential drug-drug interactions between MDR-TB treatment and widely used nucleoside reverse transcriptase inhibitors (NRTIs) in HIV-positive children. Population pharmacokinetic models were developed for lamivudine (n = 54) and abacavir (n = 50) in 54 HIV-positive children established on NRTIs; 27 with MDR-TB (combinations of high-dose isoniazid, pyrazinamide, ethambutol, ethionamide, terizidone, fluoroquinolones, and amikacin), and 27 controls without TB. Two-compartment models with first-order elimination and transit compartment absorption described both lamivudine and abacavir pharmacokinetics, respectively. Allometric scaling with body weight adjusted for the effect of body size. Clearance was predicted to reach half its mature value 2 (lamivudine) and 3 (abacavir) months after birth, with completion of maturation for both drugs at 2 years. No significant difference was found in key pharmacokinetic parameters of lamivudine and abacavir when co-administered with routine drugs used for MDR-TB in HIV-positive children.

CAREGIVERS’ EXPERIENCES IN CARING FOR HIV POSITIVE CHILDREN: A QUALITATIVE STUDY AT A COMPREHENSIVE CARE CENTRE IN KENYA

Purpose: Caring for HIV positive children poses various challenges and uncertainties depending on the disclosure of their status. To explore the caregivers’ experiences in caring for HIV positive children before, during and after disclosure of their HIV positive status.&#x0D; Methodology: A qualitative study was conducted a Comprehensive Care Centre in a national referral Hospital in Kenya. The study population included parents/guardians of HIV positive children with complete disclosure of their HIV status. Data was collected through in-depth interviews. The socio-demographic characteristics of the respondents were analysed using descriptive statistics. The qualitative data is analysed by use of content analysis and presented in themes and narratives.&#x0D; Results: The results revealed that caring for these children was more challenging before disclosure than after disclosure. The main challenge was in responding to the children’s questions in regards to their health status. The questions asked by the children before disclosures include the reason for treatment, clinic follow up and when treatment will stop among others. The study further established that the parents/guardians expressed diverse fears of how the children might react during disclosure; however, the children mostly did not display the feared reactions at the moment of disclosure. Finally, the findings of this study established that care after disclosure becomes easier and that the children become more engaged in their own care.&#x0D; Conclusion: The study found that caring for HIV positive children is less challenging after disclosure of their HIV status. Further, fears by caregivers are unfounded and there are minimal negative reactions by the children upon disclosure. In order to become actively engaged in their own care, children as early as 11 years old need to be informed about their positive HIV status.&#x0D; Unique contribution to practice, theory and policy: The healthcare providers should ensure early preparation of the caregivers for disclosure to the children of their HIV status. Further, community members and school teachers need to be educated about the beneficial effects of disclosure of an HIV diagnosis to a child or adolescent. Research is needed on the development and implementation of caregiver support groups similar to that of children living with HIV.&#x0D; Purpose: Caring for HIV positive children poses various challenges and uncertainties depending on the disclosure of their status.

Clinical utility of smartphone-based audiometry for early hearing loss detection in HIV-positive children: A feasibility study.

BackgroundPaediatric human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) often manifests with hearing loss (HL). Given the impact of HL, early detection is critical to prevent its associated effects. Yet, the majority of children living with HIV/AIDS (CLWHA) cannot access hearing healthcare services because of the scarcity of audiologists and expensive costs of purchasing screening equipment. Alternative solutions for early detection of HL are therefore necessary.AimThe overall aim of this study was to assess the feasibility of using self-administered smartphone-based audiometry for early HL detection amongst CLWHA.SettingThis study was conducted at the paediatrics department of a state hospital in the Eastern Cape province, South Africa.MethodsThis was a feasibility study conducted amongst twenty-seven (27) CLWHA who were in the age group of 6–12 years. The participants self-administered hearing screening tests using a smartphone-based audiometric test. The primary end-points of this study were to determine the sensitivity, specificity and test-retest reliability of self-administered hearing screening.ResultsThe sensitivity and specificity for self-administered screening were 82% and 94%, respectively, with positive and negative predictive values of 90% and 88%, respectively. Moreover, a strong positive test-retest reliability (r = 0.97) was obtained when participants self-administered the screening test.ConclusionSix- to 12-year-old CLWHA were able to accurately self-administer hearing screening tests using smartphone-based audiometry. These findings show that self-administered smartphone audiometry can be used for serial hearing monitoring in at-risk paediatric patients.

Finding Children Living With HIV in Low-prevalence Countries: HIV Prevalence and Testing Yield From 5 Entry Points in Ethiopia.

Limited data in low HIV prevalence settings such as Ethiopia limit policy development and implementation of optimized pediatric testing approaches to close the treatment gap. This study aimed to determine HIV prevalence, testing yield and factors associated with HIV among children at 5 entry points. We conducted a cross-sectional study from May 2017 to March 2018 in 29 public health facilities in Amhara and Addis Ababa regions in Ethiopia. Children 2-14 years were enrolled through 5 entry points. Data were obtained from registers, medical records and interviews with caregivers. HIV prevalence and testing yields were calculated for each entry point. Mixed-effects logistic regression analysis identified factors associated with undiagnosed HIV. The study enrolled 2166 children, of whom 94 were HIV positive (40 newly diagnosed). HIV prevalence and testing yield were the highest among children of HIV-positive adults (index testing; 8.2% and 8.2%, respectively) and children presenting to tuberculosis clinics (7.9% and 1.8%) or with severe malnutrition (6.5% and 1.4%). Factors associated with undiagnosed HIV included tuberculosis or index entry point [adjusted odds ratio (aOR), 11.97; 95% CI 5.06-28.36], deceased mother (aOR 4.55; 95% CI 1.30-15.92), recurrent skin problems (aOR 17.71; 95% CI 7.75-40.43), severe malnutrition (aOR 4.56; 95% CI 2.04-10.19) and urban residence (aOR 3.47; 95% CI 1.03-11.66). Index testing is a critical strategy for pediatric case finding in Ethiopia. Strategies and resources can prioritize minimizing missed opportunities in implementing universal testing for very sick children (tuberculosis, severe malnutrition) and implementing targeted testing in other entry points through use of factors associated with HIV.

Estimating the burden of pediatric HIV in an \u2018A\u2019 category district in India: an epidemiological study

BackgroundIndia lacks epidemiological information on the disease burden of pediatric HIV. The National AIDS Control Program (NACP) estimates the numbers of HIV-positive children as a proportion of adult persons living with HIV. A third of HIV-positive children die before their first birthday and a half before they reach their second birthday. The early detection of HIV is crucial for the prevention of morbidities, growth delays, and death among HIV-positive children.MethodsThe study aimed to estimate the disease burden of pediatric HIV among children in ‘A’ category district of a high HIV prevalence state. An ‘A’ category district is defined by the presence of > 1% HIV prevalence among the general population, as estimated by HIV Sentinel Surveillance. The study used an innovative three-pronged strategy combining cross-sectional and longitudinal methods. The overall burden of pediatric HIV was calculated as a product of cases detected multiplied by a net inflation factor, for each of three strategies.ResultsThe existing pool of HIV infection in the district is estimated to be 3266 (95% CI: 2621–4197) HIV positive children < 15 years of age, in a mid-year (2013) projected child population of about 1.4 million, thus giving an HIV prevalence of 0.23% (CI: 0.19–0.30) among children (0–14 years of age). The proportion of children among all people living with HIV in the district works out to 10.4% (CI: 8.6–13.5%).ConclusionsThe study estimate of 0.23% HIV prevalence among children (0–14 years of age) is higher than the NACP estimates (0.02) and is 2.5 higher than the Karnataka state estimate (0.09)22. Similarly, the proportion of children among all persons living with HIV in Belgaum district is 10.4% in this study, as against 6.54% for India. The study methodology is replicable for other settings and other diseases.

A randomized controlled trial evaluating the effects of a family-centered HIV care model on viral suppression and retention in care of HIV-positive children in Eswatini.

IntroductionA family-centered care model (FCCM) providing family-based HIV services, rather than separate adult/pediatric services, has been proposed to increase pediatric retention and treatment adherence.Materials and methodsEight health-care facilities in the Hhohho region of Eswatini were randomized to implement FCCM (n = 4) or continue standard-of-care (SOC) separate adult/pediatric clinics (n = 4). HIV-positive children and caregivers were enrolled; caregiver interview and child/caregiver chart abstraction were done at enrollment and every three months; pediatric viral load was evaluated at enrollment and every six months through 12 months. Because of study group differences in 12-month viral load data availability (89.4% FCCM and 72.0% SOC children had 12-month viral load), we used three separate analyses to evaluate the effects of FCCM on children’s viral suppression (<1,000 copies/mL) and undetectable virus (<400 copies/mL) at 12 months. In the first analysis, all children with missing viral outcome data were excluded from the analysis (modified intent to treat, mITT). The second analysis used inverse probability of missingness weighted logistic regression to estimate the effect of FCCM on 12-month viral outcomes compared to SOC (weighted mITT). For the third approach, missing virologic outcome data were imputed as virologic failure (imputed ITT). We also examined factors associated with viral suppression at 12 months using multivariable logistic regression.ResultsWe enrolled 379 HIV-positive children and 363 caregivers. Among all children at enrollment, viral suppression and undetectability was 78.4% and 73.9%, respectively, improving to 90.2% and 87.3% at 12 months. In mITT and weighted mITT analyses, there was no significant difference in children’s 12-month viral suppression between FCCM and SOC groups (89.2% and 91.6%, respectively). Using imputed ITT, there was a modest increase in 12-month viral suppression in FCCM versus SOC children (79.7% and 69.8%, respectively, p = 0.051) and 12-month undetectability (78.7% and 65.7%, respectively, p = 0.015). Among the 255 children suppressed at enrollment, more FCCM versus SOC children (98.0% versus 95.3%) were suppressed at 12-months, but this was not statistically significant in mITT or weighted mITT analyses, with a marginally significant difference using imputed mITT analysis (p = 0.042). A higher proportion of children suppressed at enrollment had undetectable viral load at 12 months in FCCM versus SOC children (98.0% versus 92.5%), a statistically significant difference across analytical methods. Among the 61 children unsuppressed at enrollment, achieving suppression was higher among SOC versus FCCM children, but this difference was not statistically significant and included only 38 children; and there were no significant differences in detectable viral load at 12 months.There were no significant differences between study groups in retention or ART adherence at 12 months for children or caregivers. Factors associated with lack of viral suppression/detectability at 12 months included lack of viral suppression at enrollment and having a younger caregiver (age <25 years).ConclusionsFCCM in Eswatini was associated with a modest increase in viral suppression/undetectability at 12-months; 12-month retention and adherence did not differ by study group for children or caregivers. High levels of suppression and retention in both groups may have limited our ability to detect a difference.Trial registrationNCT03397420; ClinicalTrials.gov.

Time to First-Line Antiretroviral Treatment Failure and Its Predictors among HIV-Positive Children in Shashemene Town Health Facilities, Oromia Region, Ethiopia, 2019.

With expanding pediatric antiretroviral therapy access, children will begin to experience treatment failure and require second-line therapy. In resource-limited settings, treatment failure is often diagnosed based on the clinical or immunological criteria which occur way after the occurrence of virological failure. Previous limited studies have evaluated immunological and clinical failure without considering virological failure in Ethiopia. The aim of this study was to investigate time to first-line antiretroviral treatment failure and its predictors in Shashamene town health facilities with a focus on virological criteria. Methods. A retrospective cohort study was conducted in three health facilities of Shashamene town, Oromia Regional State, from March 1 to 26, 2019. Children aged less than 15 years living with HIV/AIDS that were enrolled on ART between January 1, 2011, and December 30, 2015, in Shashamene town health facilities were the study population. Data were extracted using a checklist, entered into EpiData version 3.1, and exported to SPSS version 20 for data analysis. Cox proportional hazard regression was used to determine the predictors of time to first-line treatment failure. Result. The median survival time to virological failure was 30 months with IQR of 24.42 to 44.25. Baseline WHO stages 3 and 4 with AHR = 5.69 (95% CI: 2.07–15.66) and NVP-based NNRT at initial treatment with AHR = 2.72 (1.13–6.54) were the independent predictors of time to treatment failure. Conclusion. The median survival time of first-line antiretroviral treatment failure was moderate in the study area as compared to other studies. The incidence density of treatment failure in this study was low as compared to other studies. The finding also demonstrated that children treated with nevirapine-based nonnucleoside reverse transcriptase inhibitors at initial and advanced WHO clinical stages at baseline were at higher risk of treatment failure.

Opportunities for Closing the Gap in HIV Diagnosis, Treatment, and Viral Load Suppression in Children in Malawi: Results From a 2015-2016 Population-based HIV Impact Assessment Survey.

Control of the pediatric HIV epidemic is hampered by gaps in diagnosis and linkage to effective treatment. The 2015-2016 Malawi Population-based HIV impact assessment data were analyzed to identify gaps in pediatric HIV diagnosis, treatment, and viral load suppression. In half of the surveyed households, children ages ≥18 months to <15 years were tested using the national HIV rapid test algorithm. Children ≤18 months reactive by the initial rapid test underwent HIV total nucleic acid polymerase chain reaction confirmatory testing. Blood from HIV-positive children was tested for viral load (VL) and presence of antiretroviral drugs. HIV diagnosis and antiretroviral treatment (ART) use were defined using guardian-reporting or antiretroviral detection. Of the 6166 children tested, 99 were HIV-positive for a prevalence of 1.5% (95% confidence intervals [CI]: 1.1-1.9) and 8.0% (95% CI: 5.6-10.5) among HIV-exposed children. The prevalence of 1.5% was extrapolated to a national estimate of 119,501 (95% CI: 89,028-149,974) children living with HIV (CLHIV), of whom, 30.7% (95% CI: 20.3-41.1) were previously undiagnosed. Of the 69.3% diagnosed CLHIV, 86.1% (95% CI: 76.8-95.6) were on ART and 57.9% (95% CI: 41.4-74.4) of those on ART had suppressed VL (<1000 HIV RNA copies/mL). Among all CLHIV, irrespective of HIV diagnosis or ART use, 57.7% (95% CI: 45.0-70.5) had unsuppressed VL. Critical gaps in HIV diagnosis in children persist in Malawi. The large proportion of CLHIV with unsuppressed VL reflects gaps in diagnosis and need for more effective first- and second-line ART regimens and adherence interventions.

Kaposi sarcoma in HIV-positive children: what are the symptoms and pathophysiology?

Abstract Background Introduction: Kaposi Sarcoma (KS) is a tumour caused by human herpesvirus 8 (HHV-8). It is more prevalent in Oriental Africa when compared to countries in the western world, and it is more aggressive in children, with a death rate close to 60%. Aims: clarify the symptoms and pathophysiology of the paediatric KS associated with human immunodeficiency virus (HIV), given the poor scientific production on the topic, and the fact that the knowledge of this disease on children is only an extrapolation of what is known in the adult. Methods Materials and methods: integrative review based on articles found in PubMed database, using the MeSH-indexed descriptors: ‘Children’ AND ‘Kaposi sarcoma’ AND ‘HIV infections’. Results Results: the seven selected studies show that, in HIV-positive children with KS, the prevalent symptoms are: skin lesions in multiple or unique sites, either isolated or associated with other lesions, such as oral and visceral, with the possibility of gastrointestinal bleeding, which could be deadly; lymphadenopathy in axillary, inguinal and cervical regions; respiratory symptoms; and anasarca. As for the pathophysiology, the most common occurrences are: cytopenia (anaemia and thrombocytopenia), both varying from moderate to severe; increased levels of CD4+ lymphocytes, which could act as predicting factor for lymphadenopathy; immunosuppression, a possible indicator for death; and increase in interleukin- 6 (IL-6) and IL-10 levels. Conclusions Conclusions: KS, caused by HHV-8, most prevalent in Africa, tends to be more aggressive in children, with main symptoms including lymphadenopathy and skin lesions, and main pathophysiological aspects including cytopenia and increase in IL-6 and IL-10.

Cryptococcal antigen carriage among HIV infected children aged 6 months to 15 years at Laquintinie Hospital in Douala

Up to 15% of deaths of people living with HIV is attributable to meningeal cryptococcosis, with nearly 75% occuring in sub-Saharan Africa. Although rare in children, it is a major cause of morbidity and mortality in people living with HIV. A strong association between cryptococcal antigenemia and the development of meningeal cryptococcosis has been shown in adults. Thus, in 2018, the World Health Organization published an updated version of its guidelines for the diagnosis, prevention and management of cryptococcal infection in adults, adolescents and the HIV-infected child. To determine the prevalence of cryptococcal antigenemia and to identify its determinants in children infected with HIV. An analytical cross-sectional study was carried out at the approved treatment center of Laquintinie hospital in Douala over a period of 4 months. Children were recruited consecutively after informed parental consent. Cryptococcal antigenemia and CD4 assay were performed using a Cryptops® immunochromatographic rapid diagnostic test and flow cytometry, respectively. The data collected included the socio-demographic, clinical and paraclinical variables of the children, as well as their antecedents. Data analysis was performed using Epiinfo software version 3.1 and SPSS 21.0. The significance threshold was set at 5%. A total of 147 children were enrolled. The mean age was 9.8 ± 4.09 years. The majority were on antiretroviral therapy (142, 96.60%). Only 13 (8.80%) were in severe immunosuppression. No child showed signs of meningeal cryptococcosis. The prevalence of cryptococcal antigenemia was 6.12%. Severe immunosuppression [OR: 10.03 (1.52-65.91), p = 0.016] and contact with pigeons [OR: 9.76 (1.14-83.65), p = 0.037] were independent factors significantly associated with the carriage of the cryptococcal antigen. We recommend screening for cryptococcal antigenemia and routine treatment with fluconazole of all HIV positive children with cryptococcal antigen whether symptomatic or not.

Socio-demographic Determinants of Undernutrition In HIV- Infected Under- Five Children

Background: The disease burden associated with HIV/AIDS is a key factor in the etiopathogenesis of undernutrition in growing children. This is aggravated by resultant social factors in HIV such as orphaning, low socioeconomic status, food insecurity, and marital status of caregivers.&#x0D; Objectives: The relationship between sociodemographic factors and malnutrition in the background of HIV was evaluated.&#x0D; Methods: A cross-sectional descriptive survey was conducted among under-five HIV positive children in Anambra State, Nigeria.&#x0D; Results: A total of 370 HIV positive under-five children comprising 208(56.2%) males and 162(43.8%) females were recruited. The mean age of the children was 44.5±12.9 months. One hundred and forty-seven (39.7%) were globally undernourished: 15.7.0% (58) underweight (WFA &lt;-2SD), 13.3% (49) wasted (WFH &lt; -2SD), and 27.9% (103) stunted (HFA &lt;-2SD). Males were significantly more stunted than females (p&lt;0.001). 77% (285) were of low socioeconomic class (SEC), 47.3% (175) had advanced HIV disease, and 68.1% (252) had been on HAART for &gt;12 months. 26% (96) were orphans, while 28.6% (106) were cared for by single parents. Being on HAART for &gt;12 months was associated with less undernutrition, while advanced HIV disease seemed to enhance it. Children of low SEC were more likely to be undernourished. Not having been breastfed, introduction of complementary feeds at age 3mo or less, poor food variety and suboptimal feeding frequency increased susceptibility to undernutrition. Orphans were more wasted and stunted than underweight. Single parenthood predisposed to undernutrition.&#x0D; Conclusions: HIV-infected children are vulnerable to malnutrition by virtue of the disease process, further compounded by interwoven social dilemma associated with HIV. It, therefore, behooves the health care provider to ensure a proactive growth monitoring and nutritional support, with prompt treatment of co-morbid debilitating infections. There is also a dire need for public health interventions targeted at single parents of low socioeconomic means.

Immunogenicity and Efficacy of Pneumococcal Conjugate Vaccine (Prevenar13®) in Preventing Acquisition of Carriage of Pneumococcal Vaccine Serotypes in Tanzanian Children With HIV/AIDS.

In every year, up to one million children die due to pneumococcal disease. Children infected with Human Immunodeficiency Virus (HIV) are mostly affected, as they appear to have higher rates of pneumococcal carriage and invasive disease. Successful immunity is dependent on mounting a sufficient immune response to the vaccine. We conducted a double blinded crossover randomised controlled trial to determine the serum antibody response (≥4-fold and geometric mean concentration) to pneumococcal vaccine (PCV13) serotypes at 3 months after second vaccination. We also determined the number and proportion of children carrying new (not present at baseline) vaccine serotypes of S. pneumoniae isolated from nasopharynx at 6 months post initial vaccination in recipients of Prevenar13® compared with those given Haemophilus influenzae-type b (Hib) vaccine (control). The study was conducted at St Augustine's also known as Teule Hospital in Muheza, Tanga Tanzania. 225 HIV infected children aged 1-14 years were enrolled from Jan 2013 to Nov 2013 and randomised to Prevenar13® or Hib vaccines each given at baseline and 2-3 months later. Nasopharyngeal and serum samples were collected at baseline and 4-6 months later. Serotyping was done by Quellung Reaction using Staten antisera. Serum antibodies were ELISA quantified. The study revealed a non-significant reduction in the acquisition of new vaccine serotypes of S. pneumoniae in the recipients of PCV13 by nearly a third compared to those who received Hib vaccine. The vaccine efficacy was 30.5% (95% confidence interval [CI] –6.4-54.6%, P = 0.100)]. The antibody response was not enough to induce a 4-fold rise in GMC in 7 of the 13 vaccine serotypes. When combining the effects of preventing new acquisition and clearing existing vaccine type carriage, the overall efficacy was 31.5% (95% CI 1.5-52.4%, P = 0.045). In the PCV13 group, the proportion of participants carrying vaccine serotype was significantly lower after 2 doses of PCV13 (30%; 32/107), compared with the baseline proportion (48%; 51/107). The introduction of PCV13 targeting HIV-positive children in a setting similar to Tanzania is likely to be associated with appreciable decrease in the acquisition and carriage of pneumococci, which is an important marker of the likely effect of the vaccine on pneumococcal disease.Clinical Trial Registration https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=335579, identifier ACTRN12610000999033.

Disclosure Status and Associated Factors Among Children on Antiretroviral Therapy in Ethiopia.

BackgroundThe World Health Organization recommends that children should be informed of their HIV status at age 6–12 years. However, disclosure of HIV status among children is very low in resource-limited areas, particularly in Ethiopia. So, the aim of this study was to determine the prevalence of disclosure and associated factors among a cohort of HIV-infected children in southwest Ethiopia.MethodsA facility-based cross-sectional study design was employed among caregivers of HIV-positive children aged 6–15 in Bench sheko and West Omo zone Southwest Ethiopia, from March 1 to April 20, 2020. Study participants were included using a consecutive sampling technique. Data were collected using a pretested interviewer administered questionnaire and checklist. A multivariable logistic regressions model was used to identify independent predictors of disclosure. The significance of association was declared by AOR at 95% confidence and a p-value <0.05.ResultsA total of 327 participants were involved in the study yielding a 95% response rate. The prevalence of HIV-positive status disclosure was 45.6% (95% CI=41.01–51.02). Caregiver secondary education and above (AOR=3.16, 95% CI=1.07–9.34), caregiver discussed about disclosure with health professionals (AOR= 9.56, 95% CI=4.88–18.74), child age 10–15 year old (AOR=3.64, 95% CI=1.64–8.08), duration on ART >5 years (AOR=5.08, 95% CI=1.57–16.37), treatment follow-up at hospital (AOR=2.23, 95% CI=1.27–5.01) and having treatment support for Children (AOR=3.84, 95% CI=1.88–7.85) were independent predictors of HIV-positive status disclosure.ConclusionDisclosure of HIV status to children is low. Caregivers educational status, caregivers discussion with health professional, older child, duration on ART of more than 5 year, getting treatment service from hospital, and having a treatment support group are factors that enable disclosure. Therefore, concerted efforts based on the findings of this study will be required to improve the disclosure status among HIV-positive children.

Retention of pediatric patients in care: a study of the Kibera Community Health Center HIV/AIDS Program

Background: In 2011, 3.4 million children were living with HIV worldwide1.&#x0D; Objectives: Describe the characteristics of pediatric patients enrolled into the HIV program at the Kibera community health center between January 2012 and March 2013. Determine the proportion of enrolled paediatric patients lost to follow up. Determine the correlates associated with retention and loss to follow up.&#x0D; Methods: The study was a retrospective cohort study of program data of all pediatric patients enrolled into the HIV pro- gram in the facility between January 2012 and March 2013. The data was analyzed using SPSS.&#x0D; Results: Of the 100 pediatric patients enrolled during the study period, 79 and 21 were HIV negative and positive respec- tively. Only 4 (5%) of the HIV exposed Infants and 11 (52%) of the HIV positive children were started on ART within the study period. The retention rate of the children at 3 months was 87% while the retention at both 12 and 15 months was 79%. There was an association between the mother or guardian disclosing their status and the retention of the child (p-value 0.026).&#x0D; Conclusion: The disclosure of the HIV status by parent/guardian to the child was associated with better retention of the children in the program.&#x0D; Keyword: Pediatric patients in care; Kibera community health center; HIV/AIDS.

Short report: knowledge and perceptions of health workers that strengthen adherence for paediatric and adolescent clients on the intensive adherence counselling program in Kampala, Uganda. A qualitative study

Background: Health care workers (HWs) support HIV positive children and adolescents with detectable HIV viral loads on the intensive adherence counselling (IAC) program to achieve viral suppression through individual adherence counselling. Low re-suppression rates of 23% showed low program effectiveness in fifteen public health facilities.&#x0D; Objectives: We set out to determine the knowledge and perceptions of HWs that support this program to improve its effectiveness.&#x0D; Methods: We conducted a qualitative study where five HWs that oversee clinical care for children on ART were interviewed about the program. Data on their knowledge of the program, and perceptions on why it was not effective was collected. Thematic analysis using the inductive approach was used. Transcripts were read, coded and emergent themes determined.&#x0D; Results: Five HWs participated and all were knowledgeable about the program. Two themes emerged as barriers to IAC program effectiveness, patient factors and health system factors. Patient factors were failure to attend appointments, failure to change adherence practices, and lack of consent. Health system factors were work overload, delay in getting results and drug stock outs.&#x0D; Conclusion: HWs are knowledgeable about the IAC program and client specific barriers should be addressed to improve viral suppression for children.&#x0D; Keywords: Intensive adherence counselling; health care worker barriers.

Balancing HIV testing efficiency with HIV case-identification among children and adolescents (2-19 years) using an HIV risk screening approach in Tanzania.

To optimize HIV testing resources, programs are moving away from universal testing strategies toward a risk-based screening approach to testing children/adolescents, but there is little consensus around what defines an optimal risk screening tool. This study aimed to validate a 12-item risk screening tool among children and adolescents and provide suggested fewer-item tool options for screening both facility out-patient and community populations by age strata (<10 and ≥10 years). Children/adolescents (2–19 years) with unknown HIV status were recruited from a community-based vulnerable children program and health facilities in 5 regions of Tanzania in 2019. Lay workers administered the screening questions to caregivers/adolescents; nurses enrolled those eligible for the study and tested all participants for HIV. For each screening item, we estimated sensitivity, specificity, positive predictive value and negative predictive value and associated 95% confidence intervals (CI). We generated a score based on the count of items with a positive risk response and fit a receiver operating characteristic curve to determine a cut-off score. Sensitivity, specificity, positive predictive value (PPV; yield) and number needed to test to detect an HIV-positive child (NNT) were estimated for various tool options by age group. We enrolled 21,008 children and adolescents. The proportion of undiagnosed HIV-positive children was low (n = 76; 0.36%; CI:0.29,0.45%). A screening algorithm based on reporting at least one or more items on the 10 to 12-item tool had sensitivity 89.2% (CI:79.1,95.6), specificity 37.5% (CI:36.8,38.2), positive predictive value 0.5% (CI:0.4,0.6) and NNT = 211. An algorithm based on at least two or more items resulted in lower sensitivity (64.6%), improved specificity (69.1%), PPV (0.7%) and NNT = 145. A shorter tool derived from the 10 to 12-item screening tool with a score of “1” or more on the following items: relative died, ever hospitalized, cough, family member with HIV, and sexually active if 10–19 years performed optimally with 85.3% (CI:74.6,92.7) sensitivity, 44.2% (CI:43.5,44.9) specificity, 0.5% (CI:0.4,0.7) PPV and NNT = 193. We propose that different short-tool options (3–5 items) can achieve an optimal balance between reduced HIV testing costs (lower NNT) with acceptable sensitivity. In low prevalence settings, changes in yield may be negligible and NNT may remain high even for an effective tool.

Medication adherence of antiretroviral drugs in HIV-positive children in Maharashtra

Background: Human immunodeficiency virus (HIV) is a viral infection that can lead to acquired immunodeficiency syndrome (AIDS). It is a virus that breaks down the CD4 cells in the immune system which weakens the immune system allowing it to be vulnerable for lethal opportunistic infections. Aim and Objective: Medication adherence of antiretroviral drugs in HIV-positive children in Maharashtra. Methodology: A prospective, observational, multi-centric study was conducted among HIV-inflicted paediatrics in Maharashtra. This study was conducted for a duration of 6 months, i.e., from October 19 to March 20 on patients under the inclusion criteria. Marathi and English versions of MARS (Medication Adherence Report Scale) questionnaire and demographic details were collected form the participants. Results: A total of 75 questionnaires were distributed and procured, filled with vital information of the participants among the three study sites. The average age of the participants was found to be 14.1 years. Overall female predominance was there (55% girls. According to our scoring scale, an adherence of 90.66% was observed among the participants, whereas the other 9.33% were considered non-adherent or partially adherent. Conclusions: The present study indicates that the HIV-inflicted paediatric patients have a good knowledge about their medical condition and were adherent to antiretroviral therapy.
