Abstract:
OBJECTIVE: The purpose of this study is to assess the clinical characteristics and the serial changes of high resolution CT (HRCT) findings and to correlate those with the results of clinical parameters in biopsy proven nonspecific interstitial pneumonia (NSIP) and usual interstitial pneumonia (UIP) with connective tissue diseases (CTD). METHODS: Retrospective analysis was made of forty patients with CTD diagnosed of NSIP and UIP from a single tertiary hospital between January 1996 and February 2006. RESULTS: UIP was common in rheumatoid arthritis, systemic sclerosis and Sjogren's syndrome, while NSIP was frequent in polymyositis/dermatomyositis. No significant difference was found in the clinical characteristics of patients with NSIP and UIP. In initial HRCT findings, extents of honeycombing and reticulation pattern were significantly more in UIP-CTD than in NSIP-CTD. In bronchoalveolar lavage (BAL) results, proportion of alveolar macrophages was significantly higher in NSIP-CTD than in UIP-CTD. In NSIP-CTD, significant increment in the extent of reticulation and honeycombing was noted in the serial HRCT findings despite the aggressive treatment. Significant correlation was found between leukocytosis and honeycombing change in NSIP-CTD. Despite no significant difference of survival between two groups, patients with UIP-CTD seem to have a higher mortality than those with NSIP-CTD. CONCLUSION: It is suggested that chest HRCT and BAL fluid analysis may be helpful in the differential diagnosis of NSIP- and UIP-CTD and leukocytosis in initial blood test might be predictive of honeycombing progression in NSIP-CTD. Further study will be required to compare with the prognosis of NSIP- and UIP-CTD.
