To understand the genetics of steroid-sensitive nephrotic syndrome (SSNS), we conducted a genome-wide association study in 987 childhood SSNS patients and 3,206 healthy controls with Japanese ancestry. Beyond known associations in the HLA-DR/DQ region, common variants in NPHS1-KIRREL2 (rs56117924, P[4.94E-20, odds ratio (OR) [1.90)

Purpose of Review We highlight the unique facets of paediatric nephrology in Africa in terms of the spectrum of kidney diseases, available diagnostic and treatment modalities, kidney healthcare financing options, paediatric nephrology manpower and the contribution of geography and demographics. Recent Findings Paediatric acute kidney injury in Africa is now commonly due to sepsis rather than gastroenteritis. Steroid-sensitive form of nephrotic syndrome is far more common than was two decades ago. Summary The hot arid climate in North Africa and the tropical climate in most of sub-Saharan Africa, and the high rate of consanguinity, sickle cell disease and HIV drive the spectrum of paediatric kidney diseases in the continent. Kidney diseases are often precipitated by infectious triggers associated with poor living conditions and little access to medical care thus resulting in late presentation and often end-stage kidney disease. Although accessibility to kidney care has improved in the continent due to training opportunities provided by international professional organisations, most children still face significant barriers to kidney care because they live in rural areas, governments spend the least on healthcare and the continent has the least density of healthcare practitioners and nephrology trainees.

Background/Aim:Helicobacter pylori infection is acquired in childhood, but there are conflicting reports on malnutrition and the infection. This study aimed to determine the prevalence of H. pylori infection among malnourished children and highlight the socioeconomic (SE) and clinical factors associated with the infection.Methodology:This was a descriptive cross-sectional study of 122 malnourished children and 120 healthy controls. Anthropometry was done for all the study participants, and the H. pylori status was determined with the use of monoclonal stool antigen test in all the participants. Logistic regression analysis was used to determine the factors that could predict the occurrence of the infection in the children.Results:Seventy percent (70.8%) of the malnourished children had moderate malnutrition, whereas 29.2% were severely malnourished. The prevalence of H. pylori in the malnourished children was 22.8% compared to 32.5% in the controls (P = 0.09). The infection was most prevalent in toddlers (60.7%). The SE class was significantly related to the infection (P = 0.01) and about a fifth (21.3%) of the malnourished children who belonged to the low SE class were H. pylori positive compared to 9.2% of the controls. About 64.3% of the malnourished children with H. pylori infection had fever and 25.8% had diarrhea. Multivariate analysis showed that stunting was significantly related to the infection (P = 0.02).Conclusion:H. pylori infection was prevalent among the toddlers and was significantly associated with stunting in this cohort of malnourished children. Screening of children for the infection is still advocated, and infected children should be referred for appropriate treatment and follow-up. The relationship between SE class and the infection still requires further research.

Subdural empyema (SDE), a common neurosurgical emergency in the developing countries, accounts for 15%-20% of localised paediatric intracranial infections. In regions where modern diagnostic tools are scarce and inaccessible, detection of SDE may be delayed with subsequent poor outcome. Percutaneous subdural aspiration in patients with open anterior fontanel may be the only surgical option in resource-poor regions of the world. This review focuses on the management outcome, including neurological outcome of these children. Clinical charts of children with SDE and treated by percutaneous subdural tap between February 2006 and August 2014 were reviewed. Demographic, clinical, radiological, bacteriological parameters and outcome data were analysed. Forty-five children with a mean age of 10.6 ± 6.2 months (range:

Little is known about cardiac surgery-associated acute kidney injury (CS-AKI) in children in developing regions of the world. The study aimed to determine the prevalence of CSAKI, associated factors and its impact on mortality and utilization of hospital services. The hospital records of children aged 0-17 years who underwent CS at an Indian hospital were reviewed. CS-AKI was defined as a rise in serum creatinine of ≥0.3 mg/dL in any 48 h and or by urine output <0.5 mL/kg/h for an 8-h period in the first five days after CS. The study included 323 children with a median age of one year (0.04-17), of whom 22 (6.8%) were neonates and 18.3% had a single ventricle. About 60% of the children had Risk Adjusted Congenital Heart Surgery-I category 1 or 2 interventions. CS-AKI occurred in 39 children (12.1%). Factors associated with CS-AKI were sepsis and intraand post-operative hypotension. In-hospital mortality was six-fold higher in children who developed CS-AKI. CS-AKI was associated with two to three days more of mechanical ventilation and Intensive care unit stay. CS-AKI occurs in children in developing countries, but at a lower frequency mainly due to the predominance of post-neonatal children undergoing less-complex CSs. CS-AKI was associated with higher in-hospital mortality and increased utilization of hospital services. Factors associated with CS-AKI included intraand post-operative hypotension and sepsis.

Background: Brain abscess in children is a neurosurgical emergency with potentially catastrophic outcome despite the advances made in neuroimaging techniques and antibiotic therapy. Symptoms are nonspecific and may vary with the child’s age, location, size, numbers and stage of abscess, and the primary source of infection. Treatment is usually with broad-spectrum antibiotics in combination and surgical evacuation in most cases or antibiotics alone in selected cases with clear-cut indications. This study was to document clinical characteristics, etiological factors, and spectrum of bacteriologic agents responsible for pediatric brain abscess in an African city, the challenges and management outcome over the study period. Methods: This was a retrospective study over an 11-year period involving 89 children who presented with brain abscess. Information of interest was extracted from the medical records of each participant. The results from data analysis were presented in charts and tables. Results: Eighty-nine children aged 0.85–15.7 years (median age of 6.4 years) met the inclusion criteria. The male-to-female ratio was 1.8:1. Headache (80%), fever (78%), and hemiparesis (78%) were the most common symptoms. Brain imaging deployed was CT scan in 56 (63%), MRI in 9 (10%), and transfontanel ultrasound scan in 24 (27%) children. Seventy-one (80%) children had antibiotics with surgical evacuation while 18 (20%) children received only antibiotics. In 19 (27%) children, the culture of the abscess was negative. In 53 (75%) children, Gram-positive aerobic organisms were isolated. A total of 75 patients (84%) had a favorable outcome. Conclusion: Pediatric brain abscess still poses significant public health challenge, especially in resource-limited regions. Successful management of brain abscess requires high index of suspicion for early diagnosis, referral, and intervention.
