[Pulmonary involvement in primary Sjogren syndrome]

We present 6 cases of patients diagnosed of Primary Sjögren's Syndrome (PSS) according to Fox's criteria (1986). Our goal was to document the pulmonary affection with bronchoalveolar lavage, transbronchial biopsy and respiratory functional assessment. We verified the double affection described for PSS: interstitial and airways. In all the cases, independently of the respiratory radiological or functional findings, we observed a variable lymphocytary alveolitis. We did not find any correlationship between this alveolitis and the histological findings. We conclude that bronchoalveolar lavage and transbronchial biopsy in the PSS are useful for the detection of early pulmonary pathology.
