    Differences of viral panel positive versus negative by real-time PCR in COPD exacerbated patients
    (TURKISH ASSOC TUBERCULOSIS & THORAX, 2019) Yormaz, Burcu.; Fındık, Duygu.; Süerdem, Mecit.
    Introduction: Exacerbations of chronic obstructive pulmonary disease (COPD) are often caused by respiratory tract infections. The aim of this study was to investigate the clinical, laboratory and computed tomography features of patients with hospitalized COPD exacerbations in which respiratory viruses were detected using a real-time polymerase chain reaction (PCR) technique. Materials and Methods: This retrospectively planned study included patients hospitalized in the chest diseases clinic due to exacerbation of COPD between November 2018-February 2019. The study included patients who had virus-specific real-time PCR, and computed tomography scans of the chest. Results: A total of 110 patients were included in the study. Respiratory viruses were identified in the nasopharyngeal swabs of 50 patients (45.5%) using the real-time PCR method, with rhinovirus (25%), influenza A (13.1%) and coronavirus (11.8%) being the most commonly isolated agents. The mean age of the patients was 68.28 +/- 9.59 years in the virus-positive group and 68.20 +/- 8.27 years in the virus-negative group (p= 0.963). Gender distribution, rate of smokers, exposure to biofuels, blood leukocyte count, neutrophil percentage, C-reactive protein (CRP) level, FEV1/FVC ratio did not significantly differ between the two groups (p> 0.05). Procalcitonin (PCT) and TEV1 values were significantly lower (p= 0.001 and p= 0.028, respectively) and the number of exacerbations was significantly higher in the virus-positive group (p= 0.001). The length of hospital stay was longer in the virus-positive group than in the virus-negative group (p= 0.012). Among the findings of computed tomography (CT) of the chest, bronchial wall thickening, cystic bronchiectasis, and emphysema did not differ significantly (p> 0.05). The rate of infiltrative lesions (tree-in-bud opacity, ground-glass opacity, atypical pneumonia) was significantly higher in the virus-positive group (p= 0.020). Conclusion: Viral respiratory tract infections should be considered in hospitalized patients with an exacerbation of COPD who have a history of frequent exacerbations, normal PCT value, and the absence of consolidation in CT scan of the chest. The use of broad-spectrum antibiotic therapy should be avoided in patients with these features.

    Effect of low-intensity pulmonary rehabilitation program on quality of life and pulmonary functions in patients with stable chronic obstructive pulmonary disease
    (WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2019) Çilekar, Sule.; Tülek, Baykal.; Kanat, Fikret.; Süerdem, Mecit.; Levendoglu, Funda.; Taşpınar, Ibrahim Tugrul.
    OBJECTIVES: The effectiveness of low-intensity pulmonary rehabilitation program applied patients with chronic obstructive pulmonary disease (COPD) in terms of exercise capacity, dyspnea scale, life quality and respiratory muscle strength. METHODS: The study included 30 patients with COPD. The program was 3 days in a week, for a 6 weeks period between December 1st 2012 and August 31st 2013. Arterial blood gas (ABG), 6 minute walking test (SMWT), respiratory function tests and respiratory muscle strength were evaluated before and after treatment. St George's breathing questionnaire (SGRQ) was used to assess quality of life. The dyspnea scores were assessed by the Modified Medical Research Council (mMRC) and the COPD Assessment Test (CAT). Patient approvals were obtained for the study. For analysis of results kolmogorov smirnov test, shapiro - wilk test, wilcoxon test and sample ttest were used. RESULTS: Of 30 patients participated in our study, 26 completed the treatment program. There were increases in SMWT distance (P = 0.049), forced expiratory volume in one second, and forced expiratory flow (FEF 25-75) value (P < 0.05); and decreases in mMRC dyspnea scale score (P = 0.001), CAT score (p = 0.003) and SGRQ score (P <= 0.001). Maximum inspiratory pressure and maximum expiratory pressure values and ABG parameters did not show significant change. CONCLUSION: Low intensity pulmonary rehabilitation therapy has positive effects on exercise capacity, dyspnea scale, walking distance, and quality of life. Patient compliance was high in this treatment modality so according to our study results, low intensity pulmonary rehabilitation treatment can be prefer to high intensity pulmonary rehabilitation treatment in COPD.
