Methods:

The study included a cohort admitted with MC (2007–2017) in a tertiary care hospital. The comorbidities, outcomes after discharge, and prognostic factors were analyzed.

Results:

Sixty-two patients (89 episodes of MC) were included. Demographic data was comparable between the early-(< 50 years) and late-onset (≥ 50 years) groups. Comorbidities included stress cardiomyopathy (14.5%), arrhythmias (6.4%), neuropathy (17.7%), pancytopenia (12.9%), encephalopathy (11.2%), neuromyotonia (4.8%), myelopathy (3.2%), and myositis (3.2%). Pulmonary embolism (P< 0.008), dysautonomia (P< 0.002), sepsis (P< 0.008), neuropathy (P< 0.002), and phrenic dysfunction (P< 0.016) were associated with prolonged ventilation. Majority of the patients (42, 67.7%) had a favorable outcome (disease status) as defined by remission/minimal manifestations at the time of last follow-up (median 36 months, IQR 15 …
