Pulmonary Medical Literatureconcerning Stevens-Johnson Syndrome | |
Chronic pulmonary complications associated with toxicPatients with toxic epidermal necrolysis (TEN) have been known to have various complications. Though pulmonary complications are often observed, they usually show an acute form; however, chronic complications are quite rare and little is known about either their incidences or clinical manifestations. We herein report a 33-year-old man who presented with chronic pulmonary complications after a recovery from TEN. At the onset of TEN, he had severe respiratory failure and artificial ventilation was instituted. Despite being extubated successfully, respiratory failure A diagnosis of chronic bronchitis with severe obstructive ventilatory impairment and bronchiectasis was made and he was treated with steroids, bronchodilators and antibiotics, however, he died 1.5 years after the onset of TEN. There have been 13 reported cases of chronic pulmonary complications with TEN or Stevens–Johnson syndrome (SJS) in the English published work. Such cases are usually classified into chronic bronchitis/bronchiolitis with obstructive change (including bronchiolitis obliterans and bronchiolitis obliterans organizing pneumonia), respiratory tract obstruction and bronchiectasis. Approximately 40% of all such patients die while the surviving continue to suffer from these complications because no curative therapy yet exists. As a result, the prognosis seems to be poor. The relationship between TEN and these chronic pulmonary complications In addition, eccrine gland involvement and an extremely high level of serum salivary amylase were observed at the onset of TEN, furthermore, Sjögren-like symptoms occurred after recovery from TEN. These findings suggested that the Sjögren-like autoimmune abnormalities induced by anti-Ro/SS-A correlated with the development of |
