Ketoacidosis at onset of type 1 diabetes mellitus in pediatric age in Spain and review of the literature.

UNLABELLED: DKA at diagnosis of T1DM is a life-threatening situation that represents the main cause of morbidity and mortality in pediatric patients with T1DM. OBJECTIVE: To determine whether the occurrence and severity of DKA at diagnosis of T1DM has suffered any changes in recent years in the Spanish paediatric population. PATIENTS AND METHODS: Data from 1169 patients with T1DM under 15 years of age was retrospectively studied (2004 -2008) for the presence and severity of DKA at the onset of T1DM, and compared to previous available studies in Spain. This study is multicentric, nationwide with eleven major Paediatric Diabetes Units involved. RESULTS: Complete data were available from 1151 patients (98%). Frequency of DKA was 39.5%, which is not significantly different from previous Spanish studies. 33.8%, children of 0-4.9 years of age, 40.8% aged 5-10.9 and 25.2% aged 11-14.9 years. Mean age of patients with DKA was significantly lower than the one of patients without DKA (7.44 +/- 4.10 versus 8.47 +/- 3.63 years). Mild DKA was occurring more frequently than moderate and severe forms (47.8%, versus 34.4% versus 17.8%, p<0.0001). Incidence of severe DKA was significantly higher in children under 4.9 years of age, especially in those younger than 2 years (p<0.001). Severe DKA led to complications in three children (cerebral oedema [n=1]), cerebral infarction (n=1) and femoral vein thrombosis (n=1). CONCLUSION: Frequency of DKA at diagnosis of T1DM in Spain is still high although most cases were mild. Children under 2 years of age seem to be at increased risk for severe DKA.

Intensive treatment of type 1 diabetes mellitus (DM1) delays and slows down the progression of chronic diabetes complications (DCCT 1993). This type of treatment in children and adolescents with DM1 has a different complexity to other stages of life and therefore, needs specialized care units. Various documents and declarations of diabetic patient's rights are evaluated, and the need for an adequate health care is emphasized. In the last decade, several projects have been developed in Europe to create a benchmark treatment of pediatric diabetes, with the aim of establishing hospitals with highly qualified healthcare to control it. The Diabetes Working Group of the Spanish Society for Pediatric Endocrinology (SEEP) has prepared this document in order to obtain a national consensus for the care of children and adolescents with type 1 diabetes in specialist Pediatric Diabetes Units, and at the same time advise Health Care Administrators to establish a national healthcare network for children and adolescents with diabetes mellitus, and organize comprehensive pediatric diabetes care units in hospitals with a reference level in quality of care.

[Current status and recommendations on the use of continuous blood glucose monitoring systems in children and adolescents with type 1 diabetes mellitus]. / Estado actual y recomendaciones sobre la utilización de los sistemas de monitorización continua de glucosa en niños y adolescentes con diabetes mellitus tipo 1.

Glucose monitoring methods have made great advances in the last decade with the appearance of the continuous glucose monitoring systems (CGMS) that measure the glucose levels in the interstitial liquid, providing information about glucose patterns and trends, but do not replace the self-monitoring of capillary glucose. Improvement in diabetes control using the CGMS depends on the motivation and training received by the patient and family and on the continuity in its use. Due to the development and widespread use of these systems in clinical practice, the diabetes group of the Sociedad Española de Endocrinología Pediátrica has drafted a document of consensus for their indication and use in children and adolescents. Only a limited number of trials have been performed in children and adolescent populations. More data are needed on the use of this technology in order to define the impact on metabolic control.

[Consensus document on continuous subcutaneous insulin infusion (CSII) treatment in paediatrics with type I diabetes]. / Documento de consenso sobre tratamiento con infusión subcutánea continua de insulina de la diabetes tipo 1 en la edad pediátrica.

This article reports on the Spanish Position Statement for the Diabetes Pediátric Group for the Spanish Pediatric Endocrinology Society (SEEP) on continuous subcutaneous insulin infusion in children and adolescents with type 1 diabetes. The practical issues about their indications, appropriate candidates, feasibility, and limits are outlined. The conclusions are based on the comprehensive review and balanced assessment of the evidence base on the international consensus and consensual answers to these questions for the participants.

[Graves-Basedow's disease in childhood and adolescence: clinical and biologic features in 49 patients]. / Enfermedad de Graves-Basedow en la infancia y la adolescencia: aspectos clinicobiológicos en 49 casos.

INTRODUCTION: Graves' disease is rare in childhood and adolescence. PATIENTS AND METHODS: Six boys and 43 girls between the ages of 2 and 18 years were evaluated. All presented diffuse goiter and symptomatology of hyperthyroidism. Concentrations of T4, FT4, T3 and TSH were determined by RIA with various sensitivities during the study. Thyroid antibodies were determined by hemagglutination. All patients were treated with antithyroid drugs. RESULTS: In five patients, growth velocity increased. In a further five patients association with other autoimmune diseases was detected. Quetelet's index was between the 90th and 97th percentiles in five patients and between 3rd and 10th in eight. Biochemical results were as follows: T4: 282.41 +/- 1.1 nmol/1; FT4: 62.98 +/- 1.1 pmol/l; T3: 4.92 +/- 0. 07 nmol/l) and TSH: > 0.002-0.001 mU/l. Values of TSI/TRAb were 33. 23 +/- 1.95 U/l. Four total remissions and 1 partial remission were observed. Four patients underwent surgery and eight received radioiodine. CONCLUSIONS: Few remissions were obtained with medical treatment. Radioiodine seems to be a therapeutic alternative.
