The analysis revealed also differences between the genotypes of IL-1RN in ROP patients with intrauterine infection and in patients who had ROP without intrauterine infection; however, this was not statistically significant. Other studied polymorphisms were not associated with ROP development or its progression. These results suggest that different genotypes of IL-1RN might have an impact on the course of ROP. Genotype 2/2 of IL-1RN gene may predispose to ROP progression. These results suggest that different genotypes of IL-1RN might have an impact on the course of ROP.

Hypersensitivity pneumonitis (HP) is an increasingly recognized interstitial lung disease, presenting with elevated total cell counts and high percentage of lymphocytes in bronchoalveolar lavage fluid (BALF). Despite many publications, there is no consensus in the literature concerning BALF cellular composition in patients with prolonged course of HP. The aim of the present retrospective study was to investigate the influence of disease duration, smoking habits, and the extent of lung fibrosis on BALF cells' population in patients with newly recognized HP. In total, 94 patients (49 females, 45 males), mean age 52 (±12) years, with HP recognized according to recently proposed criteria, were enrolled into the present study. Chest CT scans were retrospectively reviewed by two independent radiologists. BALF evaluation was performed as a part of routine diagnostics according to recent recommendations. Percentage of lymphocytes in BALF was significantly lower in patients with lung fibrosis (stage 1 and 2) comparing to those without lung fibrosis (stage 0). Significant correlation was also found between the percentage of BALF lymphocytes and plethysmographic lung volumes, but not with lung transfer capacity for carbon monoxide (TLCO% pred). Smoking did not influence BALF results in our study
