Future studies are needed to examine the significance of chronic interstitial pneumonitits and UIP pattern in fibrotic sarcoidosis as a potential marker for progressive disease, and the roles of PTGS2 polymorphism in various ethnic groups and Sp1/Sp3 binding in other fibrotic lung diseases.
Carriers of the homozygous CC genotype of the COX2.8473 T > C polymorphism had a higher risk of sarcoidosis compared with TT carriers (OR: 3.08; 95% CI: 1.2-7.7; p = 0.035).
