PNEUMONITE POR METOTREXATO NA ARTRITE REUMATÓIDE: RELATO DE CASO
##plugins.themes.bootstrap3.article.details##
O metotrexato (MTX) é um agente imunomodulador utilizado como modificador de doenças reumatológicas, pode ter efeitos tóxicos principalmente nos níveis hematológicos, cutâneos e de hipersensibilidade que incluem órgãos como o pulmão, na forma de pneumonites. Apresentamos o caso clínico de uma paciente de 51 anos com artrite reumatoide (AR), que apresentou pneumonite induzida por metotrexato com melhora subsequente do quadro clínico após a suspensão do medicamento e início da corticoterapia. Diferente do que se possa pensar, a pneumonite por metotrexato, por ser tão rara, deve ser considerada um diagnóstico de exclusão, dada a semelhança do quadro clínico com entidades mais comuns, como doenças pulmonares infecciosas e inflamatórias e doenças autoimunes.
