Category: Parkinsonism, Atypical: MSA
Objective: To compare the Unified Multiple System Atrophy Rating Scale (UMSARS) part I-item 2 with an ear/nose/throat (ENT) expert physician assessment.
Background: Early and severe pharyngo-laryngeal signs, including dysphagia and stridor, are peculiar signs of Multiple system atrophy (MSA), possibly presenting a source of major disability and a predictor of poor outcome. MSA dysphagia is routinely assessed by the UMSARS part I-item 2.
Method: We retrospectively analyzed the data of MSA patients who underwent an ENT assessment (nasofibroscopic and radioscopic exam) and an annual UMSARS assessment. Deglutition Handicap Index (DHI) and pulmonary/nutrition complications were collected.
Results: Seventy-five MSA patients were included. Overall, patients had a mean (SD) age of 63.49 (7.56) years and a mean (SD) disease duration of 4.17 (2.35) years at the time of neurological/ENT assessment. According to the UMSARS “swallowing” item patients were classified as follows: 18 (24%) at level 1, 35 (46.6%) at level 2, 17 (22.6%) at level 3 and 5 (0.6%) level 4 with nasogastric tube or gastrostomy feeding (Table 1). The ENT assessment revealed more severe dysphagia compared to the UMSARS part I-item 2 score (p=0.003) (Figure 1). A higher proportion of patients with impaired protective mechanisms showed severe UMSARS-based dysphagia (p=0.005). Patients with choking and oral/pharyngeal transit defects and nutritional complications were equally distributed across UMSARS part I-item 2 scores. Worse UMSARS part I-item 2 scores had worse DHI scores.
Conclusion: The UMSARS-based assessment of dysphagia does not capture key aspects of pharyngo-laryngeal dysfunction reflecting swallowing efficiency. However, the early detection of these impairments by an ENT assessment may more efficiently allow the implementation of strategies to prevent malnutrition and aspiration pneumonia.
