Résumé
Contexte : Les anticorps anti-MDA5 sont fortement associés à la dermatomyosite amyopathique clinique. Les patients développent fréquemment une pneumopathie interstitielle diffuse (PID) pouvant conduire à une insuffisance respiratoire. Le pronostic sombre rend le diagnostic précoce et précis crucial. Présentation du cas : Nous présentons le cas d’un patient nord-africain ayant subi un diagnostic retardé et présentant une insuffisance respiratoire hypoxémique sévère. Dans le contexte de la pandémie de COVID-19, cette présentation clinique peut poser un problème de diagnostic différentiel. Le patient a reçu une thérapie par bolus de stéroïdes ainsi que du cyclophosphamide avec une amélioration progressive de l’état respiratoire. Conclusions : Ce cas met en lumière l’importance du dépistage des anticorps anti-MDA5 chez les patients hypomyopathiques présentant une PID à progression rapide.
