RESUMO
BACKGROUND/AIMS: Two earthquakes on February 6th, 2023 destroyed ten cities in Türkiye. We report our experience with pediatric victims during these catastrophes, with a focus on crush syndrome related-acute kidney injury (Crush-AKI) and death. METHOD: A web-based software was prepared. Patient demographics, time under rubble (TUR), admission laboratory data, dialysis, and kidney and overall outcomes were asked. RESULTS: 903 injured children (median age: 11.62 years) were evaluated. Mean TUR was 13 h (Interquartile range-IQR: 32.5), max 240 h). 31 of 32 patients with a TUR of >120 h survived. The patient who rescued after ten days survived.Two-thirds of the patients were given 50 mEq/L sodium-bicarbonate in 0.45% sodium-chloride solution on admission day. 58% of patients were given intravenous fluid (IVF) at a volume of 2000-3000 mL/m2 body surface area (BSA), 40% of 3000-4000 mL/m2 BSA, and only 2% of >4000 mL/m2 BSA. 425 patients had surgeries, 48 suffered from major bleeding. Amputations were recorded in 96 patients. Eighty-two and 66 patients required ventilator and inotropic support, respectively.Crush-AKI developed in 314 patients (36% of all patients). 189 patients were dialyzed. Age > 15 years, creatine phosphokinase (CK)≥20 950 U/L, TUR≥10 h, and the first-day IVF volume < 3000-4000 mL/m2 BSA were associated with Crush-AKI development. 22 deaths were recorded, 20 of 22 occurred in patients with Crush-AKI and within the first 4 days of admission. All patients admitted after 7 days survived. CONCLUSIONS: This is the most extensive pediatric kidney disaster data after an earthquake. Serum CK level was significantly associated with Crush-AKI at the levels of >20 950 U/L, but not with death. Adolescent age and initial IVF of less than 3000-4000 mL/m2 BSA were also asscoiated with Crush-AKI. Given that mildly injured victims can survive longer periods in the disaster field, we suggest uninterrupted rescue activity for at least 10 days.
RESUMO
A 6-month-old girl, previously diagnosed with cystic fibrosis (CF), was admitted to hospital for nephrolithiasis. Her parents were first-degree cousins. The patient underwent endoscopic stone management. Despite no family history of stones and medical treatment with potassium citrate, the patient developed recurrent renal stones and atypical urinary tract infections during follow-up. Basic investigations were all normal. Due to consanguinity and early presentation of nephrolithiasis, metabolic causes such as cystinuria and hyperoxaluria were considered. Cystinuria was excluded due to normal cystine levels. High urinary oxalate excretion was found as expected due to absorptive (secondary) hyperoxaluria in CF patients. An early stone burden in the patient with a history of medical treatment and consanguinity led us to perform a genetic testing. Genetic testing revealed a missense homozygous variant in exon 1 of the AGXT gene. The patient was diagnosed with primary hyperoxaluria type 1. Two rare life-threatening genetic diseases were found together in the same child.
RESUMO
Objective: In patients with end-stage kidney disease, kidney transplantation is the kidney replacement therapy option that provides the most successful survival. However, immunosuppression agents administered after kidney transplantation can increase the risk of opportunistic infections. Microsporidia are obligate intracellular pathogens that can be fatal in immunosuppressed patients. The present study aimed to determine the prevalence of microsporidia in kidney transplantation recipients and the molecular characterization of the detected species. Methods: To evaluate the prevalence of renal microsporidiosis in kidney transplant recipients, the urine samples from a total of 325 patients were analyzed by real-time and nested polymerase chain reaction for Encephalitozoon spp. and Enterocytozoon bieneusi. Results: Only one (0.4%) sample from the adult patient was positive for the Encephalitozoon species, while no positivity was found in pediatric patients. It was determined as Encephalitozoon intestinalis by ITS rRNA gene region sequence analysis. A microsporidia species obtained from humans in Türkiye has been characterized for the first time and registered in GenBank. Conclusion: Our epidemiological results show that the prevalence of renal microsporidiosis in kidney transplant recipients is very low. In addition, as a result of the phylogenetic analysis of the detected isolate, it was observed that it was 100% identical to the isolates reported from dogs in Kayseri, Türkiye. This situation provided essential data regarding the zoonotic transmission dynamics of microsporidia.

ABSTRACT Objective: The objective of this study was to assess serum and urinary magnesium levels in children who have chronic kidney disease stages 1-3. Methods: Eighty-seven patients who were followed at pediatric nephrology department for chronic kidney disease were included in the study. Age, gender, magnesium, dietary magnesium, and creatinine levels, and fractionated magnesium excretion for all cases were recorded. Patients with chronic kidney disease and control groups were compared in terms of these data. Results: Thirty-nine cases with chronic kidney disease were stage 1, 26 were stage 2, and 22 were stage 3. Average age was 9.9 ± 2.8 years in the control group and 10.2 ± 2.6 years in the chronic kidney disease group. The serum magnesium levels were significantly higher in the stage 3 group than in the control group (P<0.001). Also, in stage 3, fractionated magnesium excretion levels were higher compared to the control group (P<0.001). Conclusion: In chronic kidney disease with advancing renal failure, hypermagnesemia is frequently seen. Serum magnesium levels should be measured periodically in all the children with chronic kidney disease stage 3 to investigate magnesium abnormalities and assess clinical results.
RESUMEN Objetivo: El objetivo de este estudio fue evaluar los niveles de magnesio sérico y urinario en niños con enfermedad renal crónica en estadios 1-3. Material y métodos: Se incluyeron en el estudio 87 pacientes que tuvieron seguimiento en el servicio de nefrología pediátrica por enfermedad renal crónica. Se registraron los siguientes datos: edad, sexo, niveles de magnesio, ingesta de alimentos con magnesio, y creatinina, así como también la excreción fraccionada de magnesio para todos estos casos. Sobre la base de dichos datos, se compararon los pacientes con enfermedad renal crónica y los grupos de control. Resultados: De los 87 casos de enfermedad renal crónica, 39 se hallaban en estadio 1; 26, en estadio 2, y 22, en estadio 3. La edad promedio fue de 9,9 ± 2,8 años en el grupo control y de 10,2 ± 2,6 años en el grupo de enfermedad renal crónica. Los niveles de magnesio en suero fueron significativamente más altos en el grupo del estadio 3 que en el grupo control (p <0,001). Además, en el estadio 3, los niveles de excreción fraccionada de magnesio fueron más altos en comparación con el grupo control (p <0,001). Conclusión: En la enfermedad renal crónica con insuficiencia renal avanzada, se observa con frecuencia una hipermagnesemia. Los niveles séricos de magnesio deben medirse periódicamente en todos los niños con enfermedad renal crónica en estadio 3 para investigar las anomalías del magnesio y evaluar los resultados clínicos.
