A pre-COVID-19 assessment of aspects of the school health programme in some selected Nigerian primary schools: implications for school re-opening during the COVID-19 pandemic in developing country contexts.

BACKGROUND: Following the COVID-19 pandemic, school closures were part of the global public health response to limit community spread of the virus. In recent times, there has been an emphasis on safe school re-opening. This concept is likely to differ between developed and developing country settings. There are however no published studies on barriers hindering safe school re-opening within developing country contexts. This study evaluates aspects of the school health program (SHP) in some selected Nigerian schools that might relate to the pandemic control during school re-opening. METHODS: In 2017, we conducted a cross-sectional survey of the SHP of 146 registered primary schools in Gwagwalada Area Council in Abuja, Nigeria. These schools provided services to about 54,562 students. We used direct observational methods and interviewer-administered questionnaires to assess the SHP of each school. We compare SHP characteristics that might relate to COVID-19 control in schools across government-owned (public) and privately-owned (private) schools using a pre-defined framework. RESULTS: Public school to pupil ratios was more than six times that of private schools. Only 6.9% of all surveyed schools employed qualified health personnel. Although 8 in every 10 schools conducted health talks for communicable disease control, the use of temporary isolation and school-based immunization were low at 1.4 and 2.7% respectively. Pipe-borne water access was present in 4 of 10 schools, with public schools having more limited access than private schools (p = 0.009). Similarly, less proportion of public schools had access to soap for handwashing (p < 0.001). Adequate classroom ventilation was present in 63% of surveyed schools, with private schools having more limited ventilation (p < 0.001). CONCLUSIONS: Overcrowding and infrastructural deficits within developing country contexts represent barriers to safe school re-opening during the COVID-19 pandemic. In these settings, there needs to be tailored and innovative strategies which consider local practical realities when designing the COVID-19 control programs during school re-opening.

Trends in the epidemiology of childhood nephrotic syndrome in Africa: A systematic review.

Background: Childhood nephrotic syndrome, if left untreated, leads to progressive kidney disease or death. We quantified the prevalence of steroid-sensitive nephrotic syndrome, steroid-resistant nephrotic syndrome, and histological types as the epidemiology of nephrotic syndrome in Africa remains unknown, yet impacts outcomes. Methods: We searched MEDLINE, Embase, African Journals Online, and WHO Global Health Library for articles in any language reporting on childhood nephrotic syndrome in Africa from January 1, 1946 to July 1, 2020. Primary outcomes included steroid response, biopsy defined minimal change disease, and focal segmental glomerulosclerosis (FSGS) by both pooled and individual proportions across regions and overall. Findings: There were 81 papers from 17 countries included. Majority of 8131 children were steroid-sensitive (64% [95% CI: 63-66%]) and the remaining were steroid-resistant (34% [95% CI: 33-35%]). Of children biopsied, pathological findings were 38% [95% CI: 36-40%] minimal change, 24% [95% CI: 22-25%] FSGS, and 38% [95% CI: 36-40%] secondary causes of nephrotic syndrome. Interpretation: Few African countries reported on the prevalence of childhood nephrotic syndrome. Steroid-sensitive disease is more common than steroid-resistant disease although prevalence of steroid-resistant nephrotic syndrome is higher than reported globally. Pathology findings suggest minimal change and secondary causes are common. Scarcity of data in Africa prevents appropriate healthcare resource allocation to diagnose and treat this treatable childhood kidney disease to prevent poor health outcomes. Funding: Funding was provided by the Canadian Institute for Health Research (CIHR) and the National Institute of Health (NIH) for the H3 Africa Kidney Disease Research Network. This research was undertaken, in part, from the Canada Research Chairs program.

Acute kidney injury in children: A study of etiology, clinical profile, and short-term outcomes at the University of Abuja Teaching Hospital, Gwagwalada, Abuja, Nigeria.

A major hindrance in programs designed to reduce deaths from acute kidney injury (AKI) is that the extent and nature of AKI are often unknown. This article reports the etiology, clinical profile, and short-term outcomes of children managed for AKI at the University of Abuja Teaching Hospital, Gwagwalada, Abuja, Nigeria. Children aged one month to 15 years managed for AKI (identified by pediatric RIFLE criteria) from January 2017 to December 2017 were followed up for a short period of four weeks following the AKI. Multivariate Cox regression model was used to analyze the predictors of mortality. An annual prevalence of 26 AKI cases per 1000 children was recorded with 43 AKI cases from 1634 children seen during the 12-month period. The median age was 48 months. Twenty-two were males (51.2%). Sepsis (20, 46.6%), acute glomerulonephritis (5, 11.6%), diarrheal dehydration (5, 11.6%), severe falciparum malaria (4, 9.3%), and hemolyticuremic syndrome (4, 9.3%) were the major causes of the AKI. Fourteen children were managed conservatively, while 29 children that required dialysis had access to it. Thirteen children died (percentage mortality of 30.2%). The hazard of dying was eight times more in male gender [95% confidence interval (CI); 1.03-72.9, P = 0.017] and was lower in children without pulmonary edema by 0.14 (95% CI; 0.03-0.63, P = 0.01). In our setting, mortality from AKI is still high, and male children and those with pulmonary edema should be closely managed for AKI to reduce this high mortality.

Tuberculosis, before and after Antiretroviral Therapy among HIV-Infected Children in Nigeria: What Are the Risk Factors?

INTRODUCTION: In Nigeria, there is a dearth of pediatric data on the risk factors associated with tuberculosis (TB), before and after antiretroviral therapy (ART). METHODOLOGY: A retrospective observational cohort study, between October 2010 and December 2013, at the Federal Medical Centre, Makurdi, Nigeria. TB was noted among children less than 15 years of age at ART enrolment (prevalent TB-PrevTB), within 6 months (early incident tuberculosis-EITB) and after 6 months (late incident tuberculosis-LITB) of a 12-month follow-up on ART. Potential risk factors for PrevTB and incident TB were assessed using the multivariate logistic and Cox regression models respectively. RESULTS: Among 368 HIV-1 infected children, PrevTB was diagnosed in 73 children (19.8%). Twenty-eight EITB cases were diagnosed among 278 children over 132 person-years (py) with an EITB rate of 21.2/100 py. Twelve LITB cases were seen among 224 children over 221.9 py with a LITB rate of 5.4/100 py. A significant reduction in the incidence rates of TB was found over time (75%, p˂ 0.001). Young age of children (12-35 months, aOR; 24, 95% CI; 4.1-146.6, p ˂ 0.001; 36-59 months, aOR;21, 95%CI;4.0-114.3, p ˂ 0.001); history of TB in children (aOR; 29, 95% CI; 7.3-119.4, P˂ 0.001); severe immunosuppression (aOR;38, 95% CI;12-123.2,p ˂ 0.001); oropharyngeal candidiasis (aOR;3.3, 95% CI; 1.4-8.0, p = 0.009) and sepsis (aOR; 3.2, 95% CI;1.0-9.6, p = 0.043) increased the risk of PrevTB. Urban residency was protective against EITB (aHR; 0.1, 95% CI; 0.0-0.4, p = 0.001). Virological failure (aHR; 4.7, 95% CI; 1.3-16.5, p ˂ 0.001) and sepsis (aHR; 26, 95% CI; 5.3-131.9, p ˂ 0.001) increased the risk of LITB. CONCLUSIONS: In our cohort of HIV-infected children, a significant reduction in cases of incident TB was seen following a 12-month use of ART. After ART initiation, TB screening should be optimized among children of rural residency, children with sepsis, and those with poor virological response to ART.

HIV-free survival according to the early infant-feeding practices; a retrospective study in an anti-retroviral therapy programme in Makurdi, Nigeria.

BACKGROUND: In Nigeria, reports of the outcomes of prevention of mother to child transmission of HIV (PMTCT) interventions had been limited to the MTCT rates of HIV, with no information on HIV-free survival (HFS) in the HIV-exposed infants over time. METHODS: A retrospective study between June 2008 and December 2011 at the Federal Medical Centre, Makurdi, Nigeria comparing HFS rates at 3 and 18 months according to the infant feeding pattern at the 6th week of life. HFS was assessed by Kaplan-Meier analysis and association of maternal and infant variables and risk of HIV acquisition or death was tested in a Cox regression analysis. RESULTS: 801 HIV uninfected infants at 6 weeks of life were studied in accordance with their reported cumulative feeding pattern. This includes 196 infants on exclusive breast feeding (EBF); 544 on exclusive breast milk substitute (EBMS) feeding and 61 on mixed feeding (MF). The overall HFS was 94.4% at 3 months and this declined significantly to 87.1% at the 18 months of age (p-value=0.000). The infants on MF had the lowest HFS rates of 75.7% at 3 months and 69.8% at 18 months. The HFS rate for infants on EBF was 97.4% at 3 months and 92.5% at 18 month whilst infants on EBMS had HFS of 99.1% at 3 months and 86.2% at 18 months. A higher and significant drop off in HFS at the two time points occurred between infants on EBMS (12.9%) compared to infants on EBF (4.9%), p-value of 0.002, but not between infants on MF (5.9%) and EBMS, p-value of 0.114 and those on MF and EBF, p-value of 0.758. In Cox regression multivariate analyses; MF, gestational age of ˂37 weeks, and a high pre-delivery maternal viral load were consistently associated with HIV infection or death at 3 months and 18 months (p˂.05). CONCLUSION: For a better HFS in our setting; MF must be avoided, efforts to deliver babies at term in mothers with reduced viral load are advocated and EBF must be promoted as the safest and the most feasible mode of infant-feeding.
