Abstract
Acute onset of chronic infl ammatory demyelinating polyneuropathy (A-CIDP) presents signifi cant diffi culties in differential diagnosis with acute infl ammatory demyelinating polyneuropathy (AIDP). The article presents review of literature about diff erential diagnosis between A-CIDP and AIDP and a clinical case of A-CIDP at 26-year-old man. The disease started after vaccination against infl uenza and an episode of enteritis, the clinical picture matched Guillain–Barré syndrome criteria, according to electromyography data: demyelinating lesion of the left facial nerve, motor and sensory fi bers of the median and ulnar nerves on both sides, demyelinating lesions of motor fi bers of the tibial nerve and peroneal nerve on both sides. Chronic infl ammatory demyelinating polyneuropathy was diagnosed. Lack of eff ect from plasma exchange was the reason for changing the treatment to pulse therapy with prednisolone (with a subsequent transition to a 1 mg/kg dose and further reduction until canceled within 16 weeks). Response to prednisolone — rapid recovery of motor functions, which worsened signifi cantly due to a new coronavirus infection during treatment in the neurology department. Further continuation of prednisolone therapy made it possible to restore motor functions completely, except mild prosopoparesis. At the same time, deep refl exes were absent; no signifi cant EMG dynamics was observed. Considering the eff ect of glucocorticosteroids and lack of positive dynamics on the second electromyography, the patient was diagnosed as A-CIDP.
