OBJECTIVE: Dysphagia is a life-threating manifestation of idiopathic inflammatory myopathies (IIM). However, we lack a univocal protocol for its treatment. The aim of this retrospective analysis was to evaluate the effectiveness of a step-up strategy by adding a 1-day pulse of IVIGs to immunosuppressants in IIM patients with refractory dysphagia diagnosed by Eating Assessment Tool (EAT)-10 and fibreoptic endoscopic evaluation of swallowing (FEES).
METHODS: Dysphagia was defined as a pharyngo-oesophageal disturbance associated with EAT-10 score ≥3 and at least one FEES abnormality among propulsion failure, solid or liquid stasis. Eighteen out of 154 IIM patients had FEES-confirmed dysphagia and underwent 1 day IVIG 2 g/kg repeated 1 month apart for 3 months, because of dysphagia refractory to high-dose glucocorticoids with methotrexate and/or azathioprine. Clinical characteristics along with myositis-specific antibodies and muscle histopathological findings were studied in FEES-dysphagia IIM and IIM control patients.
RESULTS: After three monthly doses of IVIG, EAT-10 score dropped with complete recover of defective propulsion and progressive decrease in percentage of both solid and liquid stasis. At 52-weeks' follow-up, reached in 12 patients, all these parameters were stable or further improved. An improvement in manual muscle strength test and a steroid-sparing effect of IVIG were also observed. Anti-PM/Scl 75/100 antibodies were much more frequent in the FEES-dysphagia group, while anti-Jo1 antibody was rarely detected.
CONCLUSION: Our treatment schedule with 2 g/kg IVIG was effective for IIM-associated refractory dysphagia assessed by the combination of EAT-10 and FEES. These findings need to be prospectively tested in a larger cohort of IIM patients.
