RESUMEN
La vitamina D se suplementa en individuos con o sin factores de riesgo
de deficiencia, aun cuando sus efectos a dosis y frecuencia específicos son
controvertidos. En consecuencia, nos planteamos el objetivo de revisar
exhaustivamente los efectos de la suplementación con vitamina D en los
ensayos clínicos aleatorizados en pacientes adultos, agrupados por sistema
blanco y a los criterios de valoración establecida en los objetivos. En la
búsqueda se incluyeron los ensayos clínicos publicados en los últimos 5 años
en PubMed y EBSCO, con las palabras clave “vitamina D suplementación”
y “efecto”, en inglés o español, excluyendo a los participantes ‹19 años.
Como resultado, la búsqueda inicial arrojó 91 resultados de dos bases de
datos, de ellos 71 incluidos. Un total de 24 artículos publicaron un efecto
significativo de la suplementación de vitamina D. Los efectos significativos
se identifican en 3 de 4 estudios en pacientes posmenopáusicas sobre la
densidad ósea y/o fortalecimiento del sistema musculoesquelético. Otros
efectos significativos se observaron con la suplementación en pacientes con
índice de masa corporal elevada, en el control de la glucosa y los niveles de
hemoglobina glucosilada. En conclusión, los ensayos clínicos aleatorizados
muestran efectos significativos en diferentes órganos y sistemas. El efecto
sobre el control glucémico es prometedor aun cuando existen grupos humanos
sobrerrepresentados.
