Mortality in children treated with maintenance peritoneal dialysis: findings from the international pediatric peritoneal dialysis network registry

Rationale & Objective: Research on pediatric kidney replacement therapy (KRT) has primarily focused on Europe and North America. In this study, we describe the mortality risk of children treated with maintenance peritoneal dialysis (MPD) in different parts of the world and characterize the associated demographic and macroeconomic factors. Study Design: Prospective cohort study. Setting & Participants: Patients younger than 19 years at inclusion into the International Pediatric Peritoneal Dialysis Network registry, who initiated MPD between 1996 and 2017. Exposure: Region as primary exposure (Asia, Western Europe, Eastern Europe, Latin America, North America, and Oceania). Other demographic, clinical, and macroeconomic (4 income groups based on gross national income) factors also were studied. Outcome: All-cause MPD mortality. Analytical Approach: Patients were observed for 3 years, and the mortality rates in different regions and income groups were calculated. Cause-specific hazards models with random effects were fit to calculate the proportional change in variance for factors that could explain variation in mortality rates. Results: A total of 2,956 patients with a median age of 7.8 years at the start of KRT were included. After 3 years, the overall probability of death was 5%, ranging from 2% in North America to 9% in Eastern Europe. Mortality rates were higher in low-income countries than in high-income countries. Income category explained 50.1% of the variance in mortality risk between regions. Other explanatory factors included peritoneal dialysis modality at start (22.5%) and body mass index (11.1%). Limitations: The interpretation of interregional survival differences as found in this study may be hampered by selection bias. Conclusions: This study shows that the overall 3- year patient survival on pediatric MPD is high, and that country income is associated with patient survival.International Pediatric Nephrology Association (IPNA) International Society for Peritoneal Dialysis (ISPD) Baxter Healthcare Fresenius Medical CareVersión publicada - versión final del edito

Síndrome hemolítico urémico en Chile: presentación clínica, evolución y factores pronósticos

Hemolytic-uremic syndrome (HUS) is characterized by acute renal failure, microangiopathic hemolytic anemia and thrombocytopenia. Aim: To describe the characteñstics ofpatients with the diagnosis ofHUS in Chile, and to identify the most reliable early predictors oímorbidity and moñality. Material and methods: The clinical records ofpatients with HUS aged less than 15 years, attended between January 1990 and December 2003 in 15 hospitals, were reviewed. Demographic, clinical, biochemical, hematological parameters, morbidity and mortality were analyzed. Results: A cohort of 587 patients aged 2 to 8 years, 48% males, was analyzed. Ninety two percent had diarrhea. At the moment of diagnosis, anuria was observed in 39% of the patients, hypertension in 45% and seizures in 17%. Forty two percent required renal replacement therapy (RRT) and perítoneal dialysis was used in the majoríty of cases (78%). The most frequently isolated etiological agentwas Escherichia coli. Mortality rate was 2.9% in the acute phase of the disease and there was a positive correlation between mortality and anuria, seizures, white blood cell count (WCC) >20.000/mm3 and requirements of renal replacement therapy (p <0.05). Twelve percent of patients evolved to chronic renal failure and the risk factors during the acute phase were the need for renal replacement therapy, anuria, WCC >20.000/mm3, seizures and hypertension. Conclusions: The present study emphasizes important clinical and epidemiological aspeets ofHUSin a Chilean pediatricpopulation

© 2016 Sociedad Chilena de Pediatría. Children with special health care needs" (CSHCN) is an emerging and heterogeneous group of paediatric patients, with a wide variety of medical conditions and with different uses of health care services. There is consensus on how to classify and assess these patients according to their needs, but not for their specific diagnosis. Needs are classified into 6 areas: a) specialised medical care; b) use or need of prescription medication; c) special nutrition; d) dependence on technology; e) rehabilitation therapy for functional limitation; and f) special education services. From the evaluation of each area, a classification for CSHCN is proposed according to low, medium, or high complexity health needs, to guide and distribute their care at an appropriate level of the health care system. Low complexity CSHCN should be incorporated into Primary Care services, to improve benefits for patients and families at this level. It is critical to train health ca

Modelo de atención y clasificación de «Niños y adolescentes con necesidades especiales de atención en salud-NANEAS»: recomendaciones del Comité NANEAS de la Sociedad Chilena de Pediatría

ResumenLos «niños y adolescentes con necesidades especiales de atención en salud» (NANEAS) son un grupo emergente y heterogéneo de niños y jóvenes que presentan distintos problemas de salud, cuya complejidad es variable. Existe consenso en que deben ser clasificados y cuidados en función de sus necesidades y no de sus diagnósticos. Estas necesidades se clasifican en 6 áreas: a) atención por especialistas; b) medicamentos de uso crónico; c) alimentación especial; d) dependencia de tecnología; e) rehabilitación por discapacidad; y f) educación especial. Se propone una clasificación de NANEAS basada en el requerimiento de cuidados de baja, mediana o alta complejidad, con el fin de definir un plan de trabajo que distribuya la participación de los distintos niveles de atención en su enfrentamiento. Se recomienda que los NANEAS que requieren cuidados de baja complejidad se incorporen a la atención primaria de salud, con el fin de aprovechar al máximo los beneficios para ellos y sus familias. Para lograrlo es fundamental la capacitación de los profesionales de la salud, promoviendo un trabajo coordinado, dinámico y bien comunicado entre los distintos niveles de atención. El cumplimiento de estas condiciones permitirá lograr un cuidado integral y de calidad para este grupo vulnerable de niños y adolescentes.Abstract“Children with special health care needs” (CSHCN) is an emerging and heterogeneous group of paediatric patients, with a wide variety of medical conditions and with different uses of health care services.
