Autoimmune Tracheal Cartilage Inflammation Responsive to Anti-TNF-α Therapy

Tracheal inflammation, or tracheitis, is a pathologic process that can occur secondary to a number of systemic inflammatory diseases, or it may be idiopathic in nature. Regardless of the underlying etiology, tracheitis can, in its most severe form, be life-threatening, thus making its treatment an area of interest. Our case is one of a 50-year-old man with a remote history of inflammatory bowel disease achieving clinical cure following surgical resection who presented with progressive dyspnea due to tracheal stenosis that was presumed secondary to an autoimmune and inflammatory etiology. His disease was initially refractory to recurrent surgical interventions. He ultimately achieved clinical improvement with a combination of methotrexate and the tumor necrosis factor alpha (TNF-α) inhibitor, adalimumab. While both clinical trials and standardized treatment guidelines are lacking in this domain, this case illustrates a potential role for TNF-α inhibitors in the treatment of inflammatory tracheitis, irrespective of the underlying etiology.
