- چکیده انگلیسی: Background: Theophylline may reverse steroid resistance and decrease inflammation in patients with chronic pulmonary disease and sulfur mustard (SM) induced bronchiolitis. This study was designed to assess the effects of low-dose theophylline on improvement of pulmonary function tests (PFTs) of SM exposed patients.
Methods: In this comparative observational study, a group of SM-exposed victims during the Iraq-Iran war who were treated with oral slow releasing (SR) theophylline, salmetrol, fluxitide, omeprazole and NAC (study group) were compared to a group of age and gender matched SM-exposed patients who received same medications except oral SR theophylline (historical control group). PFTs were measured at the beginning of the study and after 8 weeks of the treatment.
Results: In total, 33 subjects in the study group and 27 subjects in the control group were studied. Mean (SD) age of all subjects was 51 (14.1) years. In the study group, on the 8th week post-treatment, PFTs decreased, though the differences of tests between before and after treatment were not significant. In the control group, all the tests decreased in the same period and these reductions were not also significant. However, the changes in PFTs were significantly different between the two groups. The results of most PFTs in the controls decreased in greater extents compared to theophylline treated patients. This shows that despite theophylline was unable to improve the patients; it was partially able to decelerate the reductions in PFTs.
Conclusion: Theophylline may not improve PFTs of SM exposed patients but it may decelerate the progress of the underlying respiratory disease. Further studies in this setting with higher doses of theophylline and longer term of evaluation are needed to better understand the pathophysiological mechanism of SM induced bronchiolitis and the effectiveness of the treatment with theophylline.

- چکیده:
- چکیده انگلیسی: Background: Regarding the limited studies about effects of addiction on coagulation factors as a risk factor for increasing coagulation, and its relation to coronary artery disease, we decided to investigate the effect of opium on inflammatory and coagulation factors in a controlled setting.Methods: This case-control study was performed using two groups of smoking males addicted to opium (27 cases) and not addicted to opium (27 cases). After collecting demographic data, venous blood samples were gathered and sent to laboratory for measuring homocysteine, fibrinogen, prothrombin time (PT), partial thromboplastin time (PTT), International Normalized Ratio (INR), and C-reactive protein (CRP) quantity. In order to analyze the data, we used independent t-test plus Mann-Whitney test with significance level of P < 0.05.Findings: The average age in this study was 32.2 ± 6.2 in case group and 33.3 ± 6.2 in control group. Comparing case and control groups regarding age and education showed no significant difference (P = 0.598 and P = 0.848, respectively). Mean daily smoking in case group was 7.9 ± 5.4 and 8.1 ± 5.0 in control group. Mean smoking duration in case group and control group was 10.1 ± 6.5 and 9.0 ± 7.2 years, respectively. There was no significant difference between two groups regarding smoking duration (P = 0.567). Comparison of inflammatory and coagulation factors showed no significant difference except for CRP and fibrinogen for which P = 0.661 and P = 0.889, respectively. Consumption-based comparison of inflammatory and coagulation factors showed no significant difference except for PT in oral and inhaled consumptions which showed a significant difference (P = 0.035).Conclusion: Results of this study suggest that opium addiction can be an influential factor in blood parameters and can lead to inflammatory and coagulation processes complications.
