Change and significance of CRP and PCT levels in elderly patients with AECOPD / 重庆医学

Objective To investigate the changes and significance of serum C reactive protein (CRP) and calcitonin (PCT) levels in the elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods One hundred and twenty elderly patients with AECOPD in the respiration deplartment of our hospital from January 2013 to study One hundred and twenty elderly patients with AECOPD in our hospital from January 2013 to June 2015 were selected to conduct the study and performed the subgroup analysis according to the BODE index (body weight,dyspnea,airflow,motor function index),times of acute exacerbation within 1 year after treatment and recurrence time,and other 40 healthy subjects in the outpatient department were selected as the control group.The serum PCT and CRP levels were compared among various groups.Results Serum CRP and PCT levels in AECOPD patients with grade 1-4 of BODE index were significantly higher than those in the control group (P＜0.05),moreover in the intra-group comparison of serum CRP and PCT,the grade l＜grade 2＜grade 3＜grade 4,the differences were statistically significant (P＜0.05).Serum CRP and PCT had the significantly positive correlation with the grades of BODE index in AECOPD patients (r=0.482,0.317,P＜0.05).After treatment,serum CRP and PCT levels in AECOPD patients with recurrence occurred more than 3 months were significantly lower than those in the patients with recurrence occurred within 3 months,the difference was statistically significant (P＜0.05);serum CRP and PCT levels in the patients with more than once recurrence at 1 year after discharge from hospital were significantly higher than those in the patients with recurrence ≤once,the difference were statistically significant (P＜0.05).Conclusion The serum levels of CRP and PCT in the patients with AECOPD can reflect dyspnea,airflow limitation and motor function ability,and conducts the preliminary assessment on the patient's prognosis.

Addition of Theophylline or Increasing the Dose of Inhaled Corticosteroid in Symptomatic Asthma: A Meta-Analysis of Randomized Controlled Trials

PURPOSE: Low-dose theophylline has anti-inflammatory effects. The aim of this study was to evaluate the effects of adding theophylline compared with increasing the dose of inhaled corticosteroid (ICS) on symptomatic asthma. MATERIALS AND METHODS: The associated literature was acquired through deliberate searching and selected based on the established inclusion criteria for publications. The extracted data were further analyzed by a meta-analysis RESULTS: Four randomized, controlled, parallel studies were selected. Addition of theophylline produced a greater increase of forced expiratory volume in one second as %predicted (FEV1pred) by 2.49% [95% confidence interval (CI) 1.99-3.00; z = 9.70; p < 0.001], compared with increasing the dose of ICS. There was no difference between the two treatments in terms of peak expiratory flow (PEF). CONCLUSION: Addition of theophylline to ICS has similar therapeutic effects on improving lung function as increasing the dose of ICS in the treatment of symptomatic asthma.

Side effects of inhalation of hyperosmotic saline on sputum induction in asthmatic patients / 第三军医大学学报

0 05). Excessive bronchoconstriction occurred in one patient (1/41, 2.44%). Nausea and vomiting, pharyngeal dryness and pharyngalgia, dizziness and headache, discomfort of chest, and so on were found in other 43 9% patients, but the side effects were mild and endurable. Conclusion Sputum induction after inhalation of short acting ? 2 agonist is safe for asthmatic patients in the remission stage.
