Prognostic Value off Bronchoalveolar Lavage Lymphocyte Count in Recently Diagnosed Pulmonary Sarcoidosis (2)
All consecutive patients with recently diagnosed pulmonary sarcoidosis referred to the Laval Hospital Sarcoidosis Clinic during a period of 72 months from September 1980 to September 1986, were enrolled in this prospective study. We considered sarcoidosis recent if symptoms dated less than four months or, in asymptomatic subjects, if the first abnormal chest roentgenogram had been documented within the same period. The diagnosis of sarcoidosis was based on clinical presentation and chest x-ray abnormalities. Histologic confirmation was made by transbronchial biopsies and by other techniques (mediastinoscopy, lymph node biopsy, or salivary gland biopsy) when judged necessary. The diagnosis was also supported by excluding other entities and by the follow-up evaluation. Buy Advair Diskus Online
As part of their initial evaluation, subjects had posteroanterior and lateral lung roentgenograms, pulmonary (unction tests, and a BAL. Chest roentgenograms were interpreted according to the criteria of Scadding* by a radiologist unaware of the patients’ clinical status: stage 0, normal; stage 1, hilar adenopathies; stage 2, hilar adenopathies and pulmonary infiltrate; stage 3, pulmonary infiltrate; and stage 4, pulmonary fibrosis.
