Önceden CIDP tanısı almış bir hastada ortaya çıkan miyastenia gravis: Örtüşen otoimmün hastalıklarda klinik zorluklar
Abstract
Kronik inflamatuar demiyelinizan polinöropati (CIDP) ve miyastenia gravis (MG), nadiren birlikte görülen iki farklı otoimmün nöromüsküler hastalıktır. Stabil CIDP’si olan 52 yaşındaki erkek hasta, ilerleyici alt ekstremite ve fasyal güçsüzlükle başvurdu. Elektrofizyolojik incelemelerde nöromüsküler kavşak disfonksiyonu saptandı ve asetilkolin reseptör antikorlarının yüksek olması MG tanısını doğruladı. Piridostigmin, intravenöz immünglobulin ve rituksimab tedavisiyle klinik stabilite sağlandı. Bu olgu, CIDP’li hastalarda yeni veya atipik semptomlarda eşlik eden otoimmün hastalıkların düşünülmesinin önemini vurgulamaktadır. Elektrofizyolojik ve serolojik testlerle erken tanı, eşzamanlı CIDP ve MG yönetiminde etkilidir.

A case of myasthenia gravis emerging after prior diagnosis of CIDP: Clinical challenges in overlapping autoimmune disorders
Abstract
Chronic inflammatory demyelinating polyneuropathy (CIDP) and myasthenia gravis (MG) are distinct autoimmune neuromuscular disorders that rarely coexist. We present a 52-year-old man with stable CIDP who developed progressive lower limb weakness and facial involvement. Electrophysiological studies revealed neuromuscular junction dysfunction, and elevated acetylcholine receptor antibodies confirmed MG. Treatment with pyridostigmine, intravenous immunoglobulin, and rituximab resulted in clinical stabilization. This case shows the importance of considering overlapping autoimmune disorders in CIDP patients with new or atypical symptoms. Early recognition using electrophysiological and serological tests is important for accurate diagnosis and effective management of coexisting CIDP and MG.
