• Resumen

  • Background: Celiac disease is described in association with several autoimmune diseases, but rarely with myasthenia gravis.

    Case report: We describe the case of a 31-year-old white woman with celiac disease who presented manifestations related to a hyperactive immune system, including macroamylasemia, falsepositive anti-HCV, positive antinuclear antibody, and Raynaud’s phenomenon. The introduction of a gluten-free diet (GFD) resolved these features, but myasthenia gravis (MG) symptoms unexpectedly occurred on that occasion.

    Discussion: The role of a GFD in the course of autoimmune diseases has been studied and improvement has been reported in many diseases. However, there is no consensus in the literature regarding the course of neurological disorders associated with celiac disease. In the present case, a GFD did not prevent the appearance of symptoms related to myasthenia gravis. There are few reports on the association of celiac disease with myasthenia gravis and therefore little is known about the course and time of onset of myasthenia in celiac patients. The present case increases the knowledge about this unusual autoimmune neurological disease associated with celiac disease.
