Abstract

ABSTRACT

Objective: To describe the epidemiological and clinical characteristics of Venezuelan pediatric patients with multiple sclerosis (MS).

Methods: Database records from the National Program for MS were searched for patients with an established diagnosis of MS whose first symptoms appeared before age 18.

Results: The national database held records of 1.710 patients; 3.8% had onset of the first symptoms before age 18. 46.7% were boys, yielding an F:M ratio of 1.13:1. Many children had a disease onset characterized by motor impairment (30.7%), brainstem/cerebellum and spinal cord affectation (27.6%), headache (26%). Less frequent symptoms were sensory symptoms (8%) and optic neuritis (7%).

Discussion: Pediatric MS patients in Venezuela represent a significant proportion of all MS cases. The clinical pattern is characterized by motor symptoms at onset, and predominantly monosymptomatic presentation with a relapsing-remitting pattern. This is the first systematic attempt to estimate the prevalence of pediatric MS in Venezuela.

RESUMEN

Objetivo: Describir las características clínicas y epidemiológicas de pacientes pediátricos venezolanos con EM.

Métodos: Se revisó la base de datos del Programa Nacional para EM, identificando pacientes con diagnóstico establecido de EM antes de los 18 años de edad.

Resultados: La base de datos registró 1.710 pacientes y 3,8% tenía una edad de aparición menor de 18 años. De estes, 46,7% eran varones, dando una relación F:M de 1.13:1. Muchos niños tuvieron una aparición de la enfermedad caracterizada por déficit motor (30,7%), afectación del tronco encefálico-cerebelo y la médula espinal (27,6%), dolor de cabeza (26%). Síntomas menos frecuentes fueron sensoriales (8%) y neuritis óptica (7%).

Discusión: Los pacientes pediátricos venezolanos con MS representan una proporción significativa de todos los casos de MS. El patrón clínico está caracterizado por síntomas motores y presentación predominantemente monosintomática con patrón brote-remisión. Este es el primer intento sistemático para estimar la prevalencia de MS pediátrica en Venezuela.
