Rhythm abnormalities among hospitalised children in Lagos: a case series.

Arrhythmias refer to disturbances in heart rate or rhythm which leads to heart rates that are abnormally fast, slow or irregular. Rhythm abnormalities may be common among Nigerian children but there are only a few reports. The current write up is a clinical review of eight patients in various age groups including neonates, infants and older children. It is presented to highlight the different forms of arrhythmias that can occur in children, with varying underlying aetiology, thus, stressing the need for early recognition of arrhythmias in children, appropriate early intervention and challenges involved in their care.

Prevalence and determinants of peripheral arterial disease in children with nephrotic syndrome.

Peripheral arterial disease (PAD) is the least studied complication of nephrotic syndrome (NS). Risk factors which predispose children with NS to developing PAD include hyperlipidaemia, hypertension and prolonged use of steroids. The development of PAD significantly increases the morbidity and mortality associated with NS as such children are prone to sudden cardiac death. The ankle brachial index (ABI) is a tool that has been proven to have high specificity and sensitivity in detecting PAD even in asymptomatic individuals. We aimed to determine the prevalence of PAD in children with NS and to identify risk factors that can independently predict its development. A comparative cross-sectional study was conducted involving 200 subjects (100 with NS and 100 apparently healthy comparative subjects that were matched for age, sex and socioeconomic class). Systolic blood pressures were measured in all limbs using the pocket Doppler machine (Norton Doppler scan machine). ABI was calculated as a ratio of ankle to arm systolic blood pressure. PAD was defined as ABI less than 0.9. The prevalence of PAD was significantly higher in children with NS than matched comparison group (44.0% vs 6.0%, p < 0.001). Average values of waist and hip circumference were significantly higher in subjects with PAD than those without PAD (61.68± 9.1cm and 67.6± 11.2 cm vs 57.03 ± 8.3cm and 65.60± 12.5cm respectively, p< 0.005). Serum lipids (triglyceride, very low density lipoprotein, total cholesterol and low density lipoprotein) were also significantly higher in subjects with PAD than those without PAD [106.65mg/dl (67.8-136.7) vs 45.72mg/dl (37.7-61.3), 21.33mg/dl (13.6-27.3) vs 9.14mg/dl (7.5-12.3), 164.43mg/dl (136.1-259.6) vs 120.72mg/dl (111.1-142.1) and 93.29mg/dl (63.5-157.3) vs 61.84mg/dl (32.6-83.1), respectively p< 0.05]. Increasing duration since diagnosis of NS, having a steroid resistant NS and increasing cumulative steroid dose were independent predictors of PAD in children with NS; p< 0.05 respectively. With these findings, it is recommended that screening for PAD in children with NS should be done to prevent cardiovascular complications before they arise.

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.

Changing epidemiology of nephrotic syndrome in Nigerian children: A cross-sectional study.

BACKGROUND: Recent reports from small studies in West Africa suggest that Black children may have high rate of steroid sensitivity nephrotic syndrome (SSNS) contrary to long held knowledge. Herein, we determined the proportion of children with idiopathic nephrotic syndrome (INS) who achieved complete remission with steroid therapy and identified factors associated with complete remission. METHODS: We reviewed the medical records of 241 children with INS in two centres in Lagos from 2010 to 2019. We extracted demographic data, clinical features, laboratory values at the time of diagnosis, and receipt and response to steroids and other immunosuppressants. RESULTS: The median (interquartile range) age at diagnosis of INS was 5.1 (3.0-8.7) years and boys were 60.2% of the study population. Children with SSNS made up 85.9% (n = 207) of the study cohort. Among those aged 0-5 years, 92.6%were SSNS compared with 69.2% in those aged 11-17 years at the time of diagnosis. In addition, the proportion of children with SSNS increased from 73.8% between year 2010 and 2012 to 88.4% afterwards. Also, children with SSNS had lower serum creatinine (0.44 vs 0.70; p<0.001) and higher estimated glomerular filtration rate (101 vs 74.3 ml/min/1.73 m2; p = 0.008) at the time of diagnosis than those with steroid resistant nephrotic syndrome (SRNS). CONCLUSION: Among Black children in Lagos, the proportion with SSNS is comparable to proportions described in children of Asian and European descent. Furthermore, children with SSNS had lower serum creatinine and higher glomerular filtration rate than those with SRNS.

Overview of paediatric urology practice in lagos state university teaching hospital, Ikeja, Lagos, Nigeria.

INTRODUCTION: Paediatric urology is one of the subspecialities of urology, and in most climes, it is practised by the urologists and paediatric surgeons, and likewise in the Lagos State University Teaching Hospital (LASUTH). The urologists see and manage most of these cases in LASUTH. There has been no formal training in this subspeciality. However, both the urologists and paediatric surgeons in LASUTH have acquired some measure of skill and experience over time by virtue of the relatively high volume of the cases seen. This study is aimed at reviewing the practice of paediatric urology in the urology division of LASUTH and to advocate for formal training in an otherwise rare but direly needed subspeciality. PATIENTS AND METHODS: The ports of entry of paediatric patients with urologic conditions were assessed retrospectively over a 5-year period (2014-2018). The paediatric age range based on the Lagos State Government policy for health care is from birth to 12 years old. The ports of entry included the urologic outpatient department, paediatric and the adult surgical emergency units and the paediatric wards. Patients referred to and managed by the paediatric surgery division were excluded from this study. RESULTS: The total paediatric urology cases seen and managed by the urologist in LASUTH within the period of review were 421. A total of 363 paediatric urology cases were seen during the period under review, making up 7.96% of the urology cases seen at the surgical outpatient department. The most common cases managed were hypospadias, posterior urethral valves and hydronephrosis. A variety of other cases include priapism, circumcision and post-circumcision injuries, urethral prolapse, testicular torsion, cystic renal dysplasia, disorder of sexual differentiation and several others. Three hundred and seven surgical procedures were done in the period of review on 272 (64.6%) patients. CONCLUSION: There is a need for subspecialisation in paediatric urology to harness more specialists with a specific focus, training and interest in children and their urological conditions.

Significant Burden and Psychological Distress Among Caregivers of Children With Nephrotic Syndrome: A Cross-Sectional Study.

BACKGROUND: Childhood nephrotic syndrome (NS) follows a chronic course in most children. However, little is known about the psychosocial burden of NS on the caregivers despite evidence that caregiver burden or impairment in their well-being may alter the outcome of chronic childhood illnesses. OBJECTIVES: To determine the frequency and predictors of significant caregiver burden and psychological distress among caregivers of children with NS. DESIGN: A cross-sectional study. SETTING: Two pediatric nephrology clinics in Lagos, Nigeria. PATIENTS: We included primary caregivers of children with idiopathic NS for at least 6 months. MEASUREMENTS: The primary outcomes were psychological distress and significant caregiver burden among caregivers. METHODS: We interviewed caregivers using the 12-item General Health Questionnaire (GHQ-12) and the 6-item Zarit Burden Interview (ZBI-6). The GHQ-12 scores ≥ 3 and ZBI-6 scores ≥ 6 indicated psychological distress and significant caregiver burden, respectively. RESULTS: The caregivers were mostly mothers (77.9%) and married (92.4%), whereas the children (n = 172) were mainly male (65.1%). Most of the children (n = 152; 88.4%) had steroid-sensitive NS including 24 (14%) children with frequent relapses or steroid dependence and 20 (11.6%) with steroid-resistant NS. Of the 172 caregivers, 53 (30.8%) and 30 (17.4%) reported psychological distress and significant burden, respectively. Caregivers of children in relapse had adjusted an odds ratio (aOR) with 95% confidence interval (CI) of 2.45 (1.05-5.67) and 3.30 (1.22-8.92) of psychological distress and significant caregiver burden, respectively. Furthermore, caregivers of male children and those who needed help paying for health care had an aOR of 4.61 (1.34-15.68) and 3.06 (1.06-8.87) of significant caregiver burden, respectively. LIMITATIONS: The study was limited by its cross-sectional design and the use of generic rather than disease-specific instruments. CONCLUSION: One in every 6 caregivers of children with idiopathic NS reported significant caregiver burden, and it was associated with psychological distress. Our findings underscore the need for psychosocial support for caregivers of children with NS, especially those with identifiable vulnerability.

CONTEXTE: Le syndrome néphrotique (SN) de l'enfant suit dans la plupart des cas une évolution chronique. On en sait toutefois peu sur le fardeau psychosocial du SN pour les aidants naturels, malgré qu'il soit prouvé qu'un tel fardeau ou qu'une atteinte à leur bien-être peut altérer l'issue des maladies chroniques de l'enfance. OBJECTIF: Établir la fréquence et les facteurs prédictifs d'un important fardeau des aidants et de la détresse psychosociale chez les personnes qui prennent soin d'un enfant atteint du SN. TYPE D'ÉTUDE: Étude transversale. CADRE: Deux cliniques de néphrologie pédiatrique de Lagos au Nigéria. PARTICIPANTS: Ont été inclus les aidants naturels d'enfants atteints du SN idiopathique depuis au moins six mois. MESURES: Les principaux résultats étaient la détresse psychologique et un important fardeau chez les aidants naturels. MÉTHODOLOGIE: Nous avons interrogé des aidants naturels à l'aide d'un questionnaire en 12 points sur l'état de santé général (GHQ-12) et de l'Inventaire du fardeau en six points (Zarit Burden Interview­ZBI-6). Un résultat égal ou supérieur à 3 au GHQ-12 indiquait la présence de détresse psychologique alors qu'un résultat égal ou supérieur à 6 au ZBI-6 signifiait un important fardeau de l'aidant. RÉSULTATS: Dans la majorité des cas (77,9 %), l'aidant naturel était la mère et celle-ci était mariée (92,4 %). Les enfants (n = 172) étaient majoritairement des garçons (65,1 %). La plupart des enfants (n = 152; 88,4 %) étaient atteints d'un SN stéroïdosensible, dont 24 (14 %) avaient des rechutes fréquentes ou une dépendance aux stéroïdes. Seuls 20 patients (11,6 %) étaient atteints d'un SN résistant aux stéroïdes. Des 172 aidants naturels inclus, 53 (30,8 %) ont rapporté vivre de la détresse psychologique et 30 (17,4 %) un important fardeau des aidants. Le rapport de cote corrigé (RCc) avec intervalle de confiance à 95 % (IC 95 %) des aidants d'enfants en rechute s'établissait à 2,45 (1,05-5,67) pour la détresse psychologique et à 3,30 (1,22-8,92) pour le fardeau des aidants. En outre, les soignants d'un garçon ou ceux qui avaient besoin d'aide pour payer les soins de santé présentaient respectivement un RCc de 4,61 (1,34-15,68) et de 3,06 (1,06-8,87) pour le fardeau des aidants. LIMITES: Les résultats sont limités par la nature transversale de l'étude et par l'emploi d'instruments de mesure générique plutôt que spécifiques à la maladie. CONCLUSION: Une personne sur six s'occupant d'un enfant atteint du SN idiopathique a rapporté un lourd fardeau des aidants associé à de la détresse psychologique. Nos résultats font ressortir le besoin de soutien psychologique pour les soignants d'enfants atteints du SN, particulièrement ceux dont la vulnérabilité est facilement repérable.

Acute Kidney Injury in Children with Severe Malaria Is Common and Associated with Adverse Hospital Outcomes.

BACKGROUND: The prevalence of acute kidney injury (AKI) in children with severe malaria in sub-Saharan African may have been underestimated. The study aimed to determine the prevalence of AKI in children with severe malaria and its association with adverse hospital outcomes. METHODS: At presentation, we measured complete blood count, serum bilirubin, and serum electrolytes, urea and creatinine in children with severe malaria. At 24 h after hospitalization, we repeated serum creatinine measurement. Urine passed in the first 24 h of hospitalization was also measured. We defined AKI and its severity using the Kidney Disease: Improving Global Outcome AKI guidelines. RESULTS: The study involved 244 children (53.3% males) with a median age of 3.5 (1.9-7.0) years. One hundred and forty-four (59%) children had AKI, and it reached maximum Stages 1, 2 and 3 in 56 (23%), 45 (18.4%) and 43 (17.6%) children, respectively. The majority (86.1%) with AKI had only elevated serum creatinine. Mortality increased with increasing severity of AKI on univariate analysis but weakened on multiple logistic regression. Mortality was also higher in those with both oliguria and elevated serum creatinine than in those with elevated serum creatinine only (50% vs. 4.8%, p < 0.001). Furthermore, children with AKI spent three days more in hospital than those without AKI (p < 0.001). CONCLUSIONS: Acute kidney injury complicates severe malaria in 6 out of every 10 children and is commonly identified using elevated serum creatinine. It is also associated with adverse hospital outcome.

Three cases of prune belly syndrome at the Lagos State University Teaching Hospital, Ikeja.

Prune belly syndrome (PBS) is a rare congenital disorder affecting 2.5 to 3.8/100,000 live births worldwide. Our objective of this report is to describe clinical manifestation, laboratory, and radiological characteristics of PBS in our patients, to highlight the limitations to offering appropriate patient care due to parents demanding discharge against medical advice and the need to increase the awareness regarding this rare disease. We report three cases; all referred after birth with lax abdominal wall, congenital anomalies of kidney, and urinary tract. One of the patients had an absent right foot. They all had cryptorchidism, and in one, there was deranged renal function. The reported cases had both medical and radiological interventions to varying degrees. They all had an abdominal ultrasound which revealed varying degrees of hydronephrosis, hydroureters, and bladder changes. Voiding cystourethrogram showed vesicoureteric reflux in one of the reported cases. Urinary tract infections were appropriately treated with antibiotics based on sensitivity. PBS management in our setting remains a challenge because of strong cultural beliefs, and high rate of discharge against medical advice. Focus should be on parent education, early diagnosis, and multidisciplinary management approach.

Neonatal sepsis in a Nigerian private tertiary hospital: Bacterial isolates, risk factors, and antibiotic susceptibility patterns.

BACKGROUND/OBJECTIVES: Neonatal sepsis is an important cause of morbidity and mortality in the pediatric age group in spite of several attempts at mitigating its effects. This article determines the prevalence of neonatal sepsis and the pathogens responsible for sepsis as well as risk factors and outcome at the Babcock University Teaching Hospital. METHODS: A retrospective analysis of laboratory records of consecutive babies delivered within and outside our hospital suspected of having sepsis over a 1-year period. RESULTS: The isolation rate was 34% from 100 neonates with the predominant pathogens being coagulase-negative staphylococci (CONS), Staphylococcus aureus, and Klebsiella pneumoniae. The risk factors for sepsis were age <3 days (P = 0.03) and prematurity (P < 0.001). The mortality rate was 12% with risk factors for mortality being birth weight <2500 g (P = 0.005), prematurity (P = 0.036), premature rupture of membranes (P = 0.007), and delivery outside a tertiary hospital (P = 0.007). Meropenem, ciprofloxacin, and amikacin showed the highest rates of in vitro efficacy. CONCLUSION: We highlight the prevalent pathogens in our local facility to be a combination of CONS, S. aureus, and K. pneumoniae with susceptibility patterns showing meropenem, ciprofloxacin, and amikacin to be our most effective antimicrobials in vitro.

Knowledge of Kidney Donation Among Care Givers in Two Tertiary Hospitals in Southwest Nigeria.

One of the major challenges of kidney transplantation is shortage of kidney donors. Care givers (CGs) are potential kidney donors, but the majority of them are unwilling to donate due to inadequate knowledge on kidney donation. This study evaluated the knowledge of kidney donation and its determinants among CGs in two tertiary hospitals in Southwest Nigeria. This was a cross-sectional study that was carried out in the Kidney Care Centre (KCC), Ondo and Babcock University Teaching Hospital (BUTH), Ilishan-Remo using a self-administered pretested questionnaire that assessed knowledge of kidney donation and its determinants. Pvalue of <0.05 was taken as significant. A total of 244 respondents participated in the study. The majority were below 40 years, married, and female. The proportion of respondents with adequate knowledge of kidney donation was 63.4%. More respondents from BUTH compared to KCC had adequate knowledge of kidney donation (80% vs. 46.7%, P ≤ 0.001). Similarly, the mean knowledge score was higher in respondents from BUTH (P ≤ 0.001). Factors that determined knowledge of kidney donation were female gender (AOR: 3.43, 95% CI: 1.25-9.40, P = 0.02) and social class (AOR: 1.22, 95% CI: 0.50-2.95, P ≤ 0.001). There was positive correlation between knowledge of kidney donation among the respondents from both hospitals and their willingness to donate kidneys (r = 0.439, P ≤ 0.001). Knowledge of kidney donation was better among BUTH's respondents. Gender and social class were predictors of knowledge of kidney donation. Improving knowledge of kidney donation may improve willingness to donate among the public.
