Resumen
Pelagra es el nombre que se le ha dado a la condición poco conocida, resultado del déficit de vitamina B3 o niacina, una enfermedad potencialmente mortal la cual es caracterizada por una triada clásica de diarrea, dermatitis y delirio, que está asociada a factores de riesgo como desnutrición, pobreza, ingesta de ciertos medicamentos, alteraciones metabólicas entre otros. Pelagra es una enfermedad de diagnóstico clínico que difícilmente se considera en los diagnósticos diferenciales de pacientes que consultan en servicios de emergencias o que se encuentran internados en salones de hospitales y es de suma importancia debido a la mortalidad que conlleva un diagnóstico tardío.
