Myasthenia gravis and pregnancy: Lessons learned from a complex a case report

Abstract

Myasthenia gravis primarily affects young adults, with a higher incidence in women, particularly between the ages of 20 and 30. When a young woman with myasthenia gravis contemplates pregnancy, healthcare providers must consider the potential implications. The interplay between hormonal factors and changes in the immune system establishes a complex relationship between myasthenia gravis and pregnancy. On one hand, pregnancy can alter the course of the disease, while on the other hand, the disease can impact the progression of the pregnancy and the well-being of the fetus. In this case report, we present the case of a 28-year-old woman suffering from myasthenia gravis who had undergone a thymectomy 5 years ago and was being treated with an acetylcholinesterase inhibitor. After a planned conception, the patient presented a relapse of her disease during the third trimester of pregnancy, with the onset of severe hydramnios. This observation highlights a specific case of decompensation of myasthenia gravis during pregnancy, associated with the presence of severe hydramnios. Subsequently, we delve into the existing literature to examine the reciprocal influence between myasthenia gravis and pregnancy, as well as the effects of anti-myasthenic treatments on pregnancy outcomes.
