sirolimus and Sarcoidosis

Background Sarcoidosis is an inflammatory, granulomatous disease of unknown cause affecting multiple organs, including the heart. Untreated, unresolved granulomatous inflammation can lead to cardiac fibrosis, arrhythmias, and eventually heart failure. Here we characterize the cardiac phenotype of mice with chronic activation of mammalian target of rapamycin (mTOR) complex 1 signaling in myeloid cells known to cause spontaneous pulmonary sarcoid-like granulomas. Methods and Results The cardiac phenotype of mice with conditional deletion of the

A 15-year-old girl presented with gradual-onset dysphonia and dysphagia. Laryngoscopy revealed significant supraglottic airway obstruction with swelling of both the epiglottis and arytenoids. After emergency tracheostomy, biopsy of the epiglottis revealed lymphoid hyperplasia with focal non-necrotising granulomata, leading to a presumed diagnosis of laryngeal sarcoidosis. Treatment with prednisolone and methotrexate produced minimal clinical improvement. A switch to sirolimus was followed by significant reduction in the laryngeal swelling, allowing decannulation of the tracheostomy. Treatment with sirolimus should be considered as a steroid sparing agent in laryngeal sarcoidosis, particularly in the presence of lymphoid hyperplasia on biopsy.
