Increased thrombin activity after allergen challenge: a potential link to airway remodeling?

abstract：:At the time of diagnosis, many sarcoidosis patients have no clinical indication for corticosteroid therapy, and prognostic parameters predicting deterioration are missing. In the present study, we investigated parameters derived from bronchoalveolar lavage (BAL) and serum in 77 patients with recently diagnosed sarcoid...
