POS0908 NAILFOLD CAPILLAROSCOPY FINDINGS OF INTERSTITIAL PNEUMONIA WITH AUTOIMMUNE FEATURES (IPAF)

Background Objectives: We evaluated nailfold capillaroscopy (NFC) of interstitial pneumonia with autoimmune features (IPAF) and compared it that patients CTD-ILD idiopathic (IIP). Methods Patients newly diagnosed as ILD were using NFC. Baseline demographic, clinical, serological, high-resolution CT findings collected. NFC was semi-quantitatively scored six domains ranging from 0 to 18. In addition, the overall patterns (scleroderma/non-scleroderma patterns) determined. Results A total 81 (31 CTD-ILD, 18 IPAF, 32 IIP) included. The non-specific pattern most common in IPAF groups, whereas usual IIP group. semi-quantitative score group higher than or groups (5.8 vs 4.2 3.0, p < 0.001, respectively). Giant capillaries haemorrhages more frequently present scleroderma 27.8% group, none showed a pattern. Conclusion may be useful classifying into CTD-ILD/IPAF/IIP.
