ObjectiveTo evaluate the efficacy and safety of bronchoscope in the treatment of transbronchial broncholiths.MethodsThe clinical data, treatment methods, clinical efficacy and complications of 18 patients who were diagnosed with transbronchial broncholiths were etrospectively reviewed in the Respiratory Department of the Second Hospital of Lanzhou University during January 2010 to December 2017.ResultsEighteen patients were diagnosed by bronchoscopy with a total of 22 pieces of stone for transbronchial broncholiths. An elective surgical procedure was performed in 2 cases. Six cases were treated with removing broncholiths once by foreign body forceps under bronchoscope. Repeated treatments were performed in 10 patients. Two cases underwent massive hemorrhage in the process of one-time broncholiths removal by foreign body forceps under bronchoscope, and one case suffered from bronchial fistula after the broncholiths removal, all of the above 3 patients underwent surgical treatment. All patients were followed up for 5 months without any long-term complications.ConclusionsRemoval of broncholithiasis by bronchoscopic forceps can effectively treat transbronchial broncholiths with low complication and high safety. If the broncholiths cause severe distal lung tissue injury, massive hemoptysis, bronchial fistula, or the diagnosis is unclear, surgical treatment is required. When the transbronchial broncholith is difficult to remove completely at once, batch could be chosen. First, to remove one portion which causes the obstruction of airway; and then, to remove the left part of the transbronchial broncholith by stages.
Objective To evaluate the correlation between blood eosinophilia and clinical characteristics, readmission rate and mortality in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data, VIP, and CBM databases were searched until October 31, 2021. Two researchers independently screened the literature, extracted the data, and evaluated the bias risk of the included studies. Meta-analysis was conducted by Rev Man v.5.4. Results Finally, 76 observational studies met the inclusion criteria, including 15 English literatures and 61 Chinese literatures. There were 8240 patients (34.20%) in the eosinophilia group (EOS≥2%) and 15854 cases (65.8%) in the eosinophil normal group (EOS<2%). Results of meta-analysis: (1) Inflammatory Index: eosinophilia group had lower C-reactive protein [MD=–8.44, 95%CI (–10.59, –6.29), P<0.05], and lower neutrophil to lymphocyte ratio [MD=–2.47, 95%CI (–3.13, –1.81), P<0.05]. (2) Hospitalization: eosinophilia group had shorter hospital stay [MD=–2.23, 95%CI (–2.64, –1.81), P<0.05] and lower in-hospital mortality [OR=0.41, 95%CI (0.31, 0.53), P<0.05], lower mechanical ventilation rate [OR=0.59, 95%CI (0.47, 0.75), P<0.05], lower hormone use rate [OR=0.91, 95%CI (0.85, 0.96), P<0.05]. (3) Follow-up results: eosinophilia group had a lower rate of readmission at 1 year [OR=0.78, 95%CI (0.66, 0.92), P<0.05] and a lower rate of death at 1 year [OR=0.78, 95%CI (0.62, 0.97), P<0.05]. Conclusions AECOPD patients with eosinophilia group were characterized by lower inflammatory indicators, shorter hospital stay, shorter in-hospital mortality, lower mechanical ventilation rate, lower hormone use rate, lower rate of acute exacerbation readmission, lower mortality rate and lower rate of follow-up after 1 year. This kind of patients with mild disease, good treatment effect, low risk of acute exacerbation.
Objective To investigate the prevalence of depression in patients with chronic obstructive pulmonary disease ( COPD) and risk factors. Methods 215 patients with stable COPD were recruited in the study. The Patient Health Questionnaire-9 ( PHQ-9) standardized scale were performed for the depression survey. Meanwhile CAT, pulmonary function test and the history taking ( sex, age, height, weigh, smoking status, education level) were applied to evaluate all the COPD patients. The COPD patients were classified into A, B, C, and D groups according to 2011 GOLD new COPD classification system. Pearson chi-square test and multivariate logistic modeling were used to estimate the prevalence of depression and the risk factors. Results The prevalence of depression in COPD patients whose PHQ-9 scores ≥7 was 37.7% with 18.5% , 35.8% , 46.5% , and 62.5% respectively in A, B, C, and D groups. There was significant difference in prevalence between each groups ( Plt;0.05) . Compared with the COPD patients without depression, the COPD patients with depression had younger age, more female, higher education level, higher CAT scores and smaller means of body mass index ( BMI) . Logistic analysis revealed that depression in COPD was associated with age, sex, education level, BMI, FEV1% pred and CAT scores. The patients who with younger age, female sex, higher education level, lower FEV1% pred, lower BMI and higher CAT scores were had higher rsik to be complicated with depression. However no significant difference was observed between different FEV1 /FVC or smoking status. Conclusions This study confirms the high prevalence of depression in patients with stable COPD, and the prevalence in A, B, C, and D groups of COPD are different. Sex, age, education level, FEV1% pred, BMI, and CAT scores are the risk factors of depression in COPD.
