Vitamin D deficiency in pediatric patients using antiepileptic drugs: systematic review with meta-analysis / Deficiência de vitamina D em pacientes pediátricos que fazem uso de fármacos antiepilépticos - revisão sistemática com metanálise

Abstract Objectives: To measure the prevalence of vitamin D deficiency (through the 25-hydroxyvitamin D metabolite) in pediatric patients using antiepileptic drugs. Source of data: Meta-analysis of studies identified through search in the PubMed, Embase, LILACS, and Cochrane Library databases, on February 19, 2019. Summary of data: A total of 748 articles were identified, 29 of which were relevant to the objectives of this study. The prevalence of vitamin D deficiency found was 0.32 (95% CI = 0.25-0.41; I 2 = 92%, p < 0.01). In the subgroup analyses, the most significant results were observed in the group of patients using cytochrome P450-inducing antiepileptic drugs, with a prevalence of 0.33 (95% CI = 0.21-0.47; I 2 = 86%, p < 0.01) and, considering the study design, in the subgroup of cohort studies, with a prevalence of 0.52 (95% CI = 0.40-0.64; I 2 = 76%, p < 0.01). Conclusions: Taking into account the deleterious effects of vitamin D deficiency on the bone health of individuals using antiepileptic drugs, it is suggested to include in their care 25-hydroxyvitamin D monitoring, cholecalciferol supplementation, and treatment of the deficiency, when present.

Resumo Objetivos: Mensurar a prevalência de deficiência de vitamina D (através do metabólito 25-hidroxivitamina D) em pacientes pediátricos em uso de fármacos antiepilépticos. Fonte dos dados: Metanálise de estudos identificados por meio de pesquisa nas bases de dados Pubmed, Embase, LILACS e Cochrane em 19 de fevereiro de 2019. Síntese dos dados: Foram identificados 748 artigos, dos quais 29 mostraram-se relevantes aos objetivos deste estudo. A prevalência de deficiência de vitamina D encontrada foi de 0,32 (IC 95% = 0,25-0,41) (I2 = 92%, p < 0,01). Nas análises por subgrupos, os resultados mais expressivos foram observados no grupo de pacientes em uso de fármacos antiepilépticos indutores do citocromo P450, que apresentou prevalência de 0,33 (IC 95% = 0,21-0,47) (I2 = 86%, p < 0,01). Considerou-se o delineamento dos estudos, no subgrupo de estudos de coorte, com prevalência de 0,52 (IC 95% = 0,40-0,64) (I2 = 76%, p < 0,01). Conclusões: Levando-se em consideração os efeitos deletérios da deficiência de vitamina D na saúde óssea dos sujeitos em uso de fármacos antiepilépticos, sugere-se incluir em seu atendimento, o monitoramento de 25-hidroxivitamina D, suplementação com colecalciferol e tratamento de deficiência quando existente.

Estado epiléptico convulsivo en adultos atendidos en el Instituto Nacional de Ciencias Neurológicas de Lima, Perú 2011-2013. / Convulsive status epilepticus in adults attending the Instituto Nacional de Ciencias Neurológicas in Lima, Perú 2011-2013.

Objetivos: describir las características clínicas y la evolución del estado epiléptico convulsivo (EEC) en pacientes adultos admitidos en el Servicio de Emergencia del Instituto Nacional de Ciencias Neurológicas de Lima, Perú entre los años 2011 y 2013. Métodos: Se realizó un estudio prospectivo de serie de casos. Resultados: Se incluyeron 28 pacientes mayores de 17 años, la mediana de edad fue 31 años. El 57% fueron hombres y el 89% tenían antecedentes de epilepsia. La principal causa del EEC fue el incumplimiento de la medicación antiepiléptica (54%). El diazepam seguido de la fenitoína fue el tratamiento antiepiléptico más empleado (75%) y la frecuencia de EEC refractario fue del 4%. Conclusiones: los pacientes fueron mayoritariamente varones, adultos jóvenes, con antecedentes de epilepsia que presentaron un EEC debido el incumplimiento de la medicación antiepiléptica y respondieron favorablemente al tratamiento con diazepam seguido de fenitoína.

Objectives: to describe the characteristics features and outcome of convulsive status epilepticus (CSE) in adult patients admitted to the Emergency Department at the Instituto Nacional de Ciencias Neurológicas in Lima, Peru between 2011 and 2013. Methods: a prospective study was conducted. Results: twenty-eight patients older than 17 years were included, the median age was 31 years old. 57% were male and 89% had a history of epilepsy. Main cause of CSE was antiepileptic medication noncompliance (54%). Diazepam followed by phenytoin was the most used therapeutic regimen (75%) and the frequency of refractory CSE was 4%. Conclusion: patients were mostly male, young adults with a history of epilepsy who presented a CSE caused by the antiepileptic medication noncompliance and the response to treatment based on diazepam followed by phenytoin was positive.

Abordagem inicial e manejo das crises epilepticas na emergência / Initial approach and management of epileptic crises in emergency

Frequentemente somos confrontados com pacientes em crises convulsivas nas unidades de atendimento emergencial. Em sua grande maioria, quando chegam à emergência, geralmente as crises já cederam. Ao se deparar com recorrência de crises frequentee e seu estágio ainda mais grave, as crises que não cessam (Status Epilepticus), é essencial reconhecer esta emergência médica e abordá-la de maneira correta.

Frequently, patients with recurrent, often continuous seizures are seen at the Emergency Room. In most, the attacks have ceased before arriving at the ER, and management should contemplate diagnosis of the reason for the attack or seizure recurrence. When faced with Status Epilepticus, one of the worst outcomes a seizure can have, it is essential to recognize it as a medical emergency and approach it correctly.
