Bronchoalveolar lavage (BAL) in newly diagnosed patients with collagen vascular diseases. The Indian Journal of Chest Diseases & Allied Sciences. 1998 Oct-Dec; 40(4): 243-50http://imsear.searo.who.int/handle/123456789/29193Collagen vascular diseases (CVD) are commonly associated with interstitial lung diseases. Bronchoalveolar lavage (BAL) fluid analysis has important diagnostic value when considered in conjunction with other information. The present study was undertaken in newly diagnosed patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) at presentation to characterise BAL cellular constituents and elucidate the cellular picture in patients with and without pulmonary symptoms and in those with and without radiological (high resolution computed tomography) features of interstitial lung disease. All the patients were non-smokers and had not received any form of treatment for their diseases. The means of percentages of lymphocytes, neutrophils, and macrophages were 23.3%, 6.2%, 70.5% respectively. There was a significant BAL lymphocyte predominance in patients with pulmonary symptoms, and a lymphocyte and neutrophil predominance in those having radiological evidence of interstitial lung disease.engAdultArthritis, Rheumatoid --complicationsBiopsyBronchi --pathologyBronchoalveolar Lavage Fluid --cytologyCollagen Diseases --complicationsFemaleHumansLung Diseases, Interstitial --complicationsLupus Erythematosus, Systemic --complicationsLymphocyte CountMaleMiddle AgedPrognosisProspective StudiesPulmonary Fibrosis --complicationsSeverity of Illness IndexClinical Trial
