Introduction: Obesity in children and adolescents is a public health problem that is increasing worldwide, being known its relation with the development of metabolic alterations like diabetes mellitus type 2. Objectives: To determine the presence of insulin resistance in obese and non obese adolescents according to sex, age, pubertal stage and presence of familial metabolic or cardiovascular disorders. Design: Cross-sectional observational and analytical study. Setting: Three Lima urban educational centers. Participants: Adolescents 10 to 17 year-old. Interventions: Sixty nine adolescents between 10 and 17 years old were divided in two groups according to the presence of obesity. Obesity was defined as body mass index >95th percentile, 55,1% were male and 44,9% female. Homeostatic model assessment was employed to determine insulin resistance (HOMA-IR) and beta cell function (HOMA%B) i...

Abstract Objective: To determine clinical and biochemical characteristics in type 2 diabetes mellitus (T2DM) in pediatric patients at time of diagnosis. Design: Clinical retrospective study. Setting: Endocrinology Service, Instituto Nacional de Salud del Niño, Lima, Peru. Patients: Children with diabetes mellitus type 2. Methods: Medical records of 187 registered patients with diabetes mellitus were reviewed and 17 (9%) with T2DM were identified. Personal and familiar characteristics, symptoms and biochemical data were obtained. Main outcome measures: Clinical and biochemical characteristics of pediatric patients. Results: Average age at diagnosis was 12.8±3 years, 11 were male (64.7%) and 6 female (35.3%). All were born at term and 17.6% were macrosomic. Fourteen patients (82.4%) had a family history of T2DM.

La nefropatía constituye la complicación más grave de la diabetes mellitus tipo 1 (DMt1) siendo una de las manifestaciones iniciales la microalbuminuria. Objetivos: Determinar el comportamiento de los factores epidemiológicos, clínicos y bioquímicos en el desarrollo de microalbuminuria en pacientes con DMt1. Diseño: Estudio de casos y controles. Lugar: Servicio de Endocrinología del Instituto Nacional de Salud del Niño, Lima, Perú. Participantes: Pacientes diabéticos tipo 1 menores de 18 años. Intervenciones: Se estudió 64 pacientes portadores de DMt1, 22 con microalbuminuria y 42 sin esta manifestación, que constituyeron los casos y controles respectivamente. Se consignó como factores epidemiológicos la edad al diagnóstico, tiempo de evolución, género, antecedentes familiares de diabetes, nefropatía, dislipidemia, hipertensión arterial; como factores clínicos, el e...
