Steroid refractory disease

Seventy-three patients with steroid-refractory esophageal involvement related to PM/DM received IVIG therapy (2 gm/kg monthly). The median interval between PM/DM diagnosis and the onset of esophageal complications was 6 months. The most common clinical manifestations revealing esophageal dysfunction were dysphagia (%), coughing while eating (%), and gastroesophageal reflux into the pharynx and/or mouth (%). Twenty-five patients exhibited life-threatening esophageal complications requiring exclusive enteral feeding; 33 patients (%) with esophageal impairment developed aspiration pneumonia. Sixty patients (%) exhibited resolution of esophageal clinical manifestations, leading to a return to normal oral feeding and ablation of feeding enteral tubes. Four other patients (%) improved, although they still experienced mild dysphagia intermittently. Because of impaired cricopharyngeal muscle relaxation, another patient successfully underwent cricopharyngeal myotomy. Eight patients died from aspiration pneumonia (n = 6) and cancer (n = 2). Muscle weakness, thoracic myopathy, and aspiration pneumonia were independent predictive factors of IVIG-treated esophageal complications in PM/DM patients.
