A protease-antiprotease imbalance has been suggested as a possible pathogenic mechanism for COPD. The relationship between matrix metalloproteinase (MMP) levels and COPD severity was evaluated. Methods: Plasma levels of MMP-1, MMP-8, MMP-9, and MMP-12 were measured in 57 COPD patients and 36 normal controls. The relationship between MMP levels and lung function, quality of life, emphysema index, bronchial wall thickness, and pulmonary artery (PA)/ascending aorta (A) diameter ratio were examined using general linear regression analyses. Results: There were significant associations of MMP-1 with bronchodilator reversibility, MMP-8 and MMP-9 with lung function. Additionally, MMP-1, MMP-8, and MMP-9 levels were correlated with the emphysema index, independent of lung function. However, MMP-12 was not associated with lung function or emphysema severity. Associations between MMP levels and bronchial wall thickness, PA/A ratio, and quality of life were not statistically significant. Conclusion: Plasma levels of MMP-1, MMP-8, and MMP-9 are associated with COPD severity and can help to better understand pathogenesis of COPD.Introduction 1 Methods 4 Study design and participants 4 Clinical, laboratory, and quality of life measures 5 Statistical analysis 6 Results 8 Subject characteristics 8 Matrix metalloproteinase levels, lung function, and quality of life 9 Emphysema index, percent mean wall area, pulmonary hypertension 10 Airflow limitation and emphysema status 12 Discussion 39 Reference 44 Abstracts (Korea) 53Docto

The aims of this study were to compare the frequency of vitamin D deficiency between TB patients and controls and to monitor the changes of vitamin D levels during treatment of TB in a Korean population. Methods: We prospectively enrolled patients with newly diagnosed TB. In addition, we enrolled healthy volunteers or patients with diseases other than TB as controls. Baseline serum 25-hydroxyvitamin D (25-OHD) levels were measured in both groups and compared. In TB patients, the measurement of serum 25-OHD was repeated 1 month after treatment initiation and after completion of treatment. Results: In total, 116 patients with TB and 86 controls were recruited. The median 25-OHD level was not different in TB patients at diagnosis (13.9 ng/mL; IQR 8.80-21.8) and in controls (13.2 ng/mL; IQR 9.6-19.3) (p = 0.97). The frequency of vitamin D deficiency (โ‰ค10 ng/mL) was not different also in TB patients (36.2%) and controls (27.3%) (p = 0.21). During treatment in TB patients, the median 25-OHD level decreased significantly to 12.5 ng/mL at 1 month and 11.0 ng/mL at treatment completion (p = 0.01). Conclusions: In Koreans, the vitamin D level does not appear to be associated with the development of TB, and median level of 25-OHD decreased after treatment for TB.Maste
