Pleural T-lymphocyte subsets in amiodarone-associated pleuropneumonitis.
Two male patients presented with lung disorders with all the characteristics of amiodarone-related pneumonitis. Bilateral exudative pleural effusions were associated with pneumonitis. High lymphocytosis was present in the pleural fluid with a ratio of T-lymphocyte subsets close to that found in peripheral blood; in the blood T-lymphocyte subset ratio was nearly normal. By contrast, and as is usual in similar cases, lymphocytic alveolitis with T-lymphocyte subset imbalance was found in bronchoalveolar lavage fluid. These findings, never published so far to our knowledge, would favor a compartmentalization of the immune response inside the lung.
