Review Meta Analysis Comparative Study
Long-acting muscarinic antagonist + long-acting beta agonist versus long-acting beta agonist + inhaled corticosteroid for COPD: A systematic review and meta-analysis.
Some trials have been conducted to compare long-acting muscarinic antagonist (LAMA) + long-acting beta agonist (LABA) versus LABA + inhaled corticosteroids (ICS) for chronic obstructive pulmonary disease (COPD), but no meta-analysis were reported. Two investigators independently searched for eligible articles using the PubMed, Web of Science and Cochrane databases. Articles in authors' reference files were also regarded as candidates. ⋯ Compared with LABA + ICS, LAMA + LABA led to significantly greater improvements of trough FEV1 by 71 (95% CI: 48-95) mL, TDI by 0.38 points (95% CI: 0.17-0.58), less exacerbations with an OR of 0.77 (95% CI: 0.62-0.96) and less pneumonia with an OR of 0.28 (95% CI: 0.12-0.68). Frequencies of any adverse event, serious adverse event, adverse event leading to discontinuation, all-cause death and change of total score of SGRQ were not different in both arms. LAMA + LABA might be a better option for treating COPD than LABA + ICS.

Chronic obstructive pulmonary disease (COPD) frequently coexists with other conditions often known as comorbidities. The prevalence of most of the common comorbid conditions that accompany COPD has been widely reported. It is also recognized that comorbidities have significant health and economic consequences. ⋯ This review discusses the concepts of comorbidity and multi-morbidity in COPD in relation to the overall clinical outcome of COPD management. It also summarizes some of the currently available clinical scores used to measure comorbid conditions and their prognostic abilities. Furthermore, recent developments in the proposed mechanisms linking COPD with its comorbidities are discussed.

This retrospective national surveillance study investigated the burden of and risk factors for nosocomial exposure of pulmonary tuberculosis (TB) in intensive care units. ⋯ Nosocomial tuberculosis exposure is not uncommon in intensive care units. Performing rapid molecular diagnostic tests in those suspected of tuberculosis is recommended to reduce the risk of nosocomial exposure.

Inhaled medications have been widely applied to patients with airflow limiting non-cystic fibrosis (non-CF) bronchiectasis. However, the association between the use of inhalers and the development of haemoptysis has rarely been explored. The objective of this study was to assess the association between the risk of haemoptysis and the use of inhalers in patients with non-CF bronchiectasis. ⋯ The use of SABA and inhaled anticholinergics in patients with non-CF bronchiectasis increased the risk of haemoptysis. The risk-benefit ratio of inhaled bronchodilators should be considered in the haemoptysis-susceptible population.

Studies have shown that patients with acute eosinophilic pneumonia (AEP) and with initial eosinophilia have a milder disease than those with an initial normal peripheral eosinophil count (PEC). We investigated the effect of a rapid corticosteroid tapering strategy in AEP patients with initial eosinophilia. ⋯ Rapid corticosteroid tapering may be an acceptable treatment strategy for managing AEP patients with initial eosinophilia.
