ABSTRACT
Background: The aim of the study is to assess the effect of chronic lung disease on mortality in patients hospitalized with the diagnosis of prevariant COVID-19 Pneumonia compared to patients without chronic lung disease. Research design and methods: A cohort of 1,549 patients admitted to the pandemic clinic with a COVID-19 Pneumonia diagnosis was analyzed. Group 1 and Group 2 were compared in terms of the treatment they received, admission to intensive care, mortality and follow-up parameters. Results: The patient group with COVID-19 and lung disease consisted of 231 participants (14.91%) (Group 1). The patient group with COVID-19 but without lung disease had 1,318 participants (85.19%). Group 1 cases were found to receive more oxygen therapy and mechanical ventilation than Group 2 cases (p ≤ 0.001), Following univariate and multiple logistic regression analyses, it was determined that patients with chronic lung disease had a 25.76% higher mortality risk [OR: 25.763, 95% CI (Lower-Upper) (2.445-271.465), p = 0.007]. Conclusion: It was found that chronic lung disease contributed significantly to mortality in this study. Among chronic lung diseases, Chronic Obstructive Pulmonary Disease (COPD), lung cancer and interstitial lung diseases (ILDs) were shown to be more effective than other chronic lung diseases in patients with prevariant COVID-19 population.
ABSTRACT
The effective treatment of asthma is important in terms of improving the quality of life and decreasing the number of hospital admissions due to acute exacerbations. Parasymphatic activity is increased in patients with asthma. This is one of most important part of airway obstruction which has a great potential for reversibility. The evidence about the synergic interaction between inhaled corticosteroids (ICS), long acting beta-2 agonists (LABA), and long acting muscarinic antagonists (LAMA) encourages the use of LAMA in asthma. Tiotropium treatment was found to be successful in patients with recurrent exacerbations in whom asthma was uncontrolled despite treatment with other add on treatments that were recommended at GINA step 4. These findings triggered several clinical studies on fixed dose ICS/LABA/LAMA for asthma treatment. Three studies that have been published recently showed that fixed dose ICS/LABA/LAMA improved the lung functions and decreased the exacerbation rate without increasing the dose of ICS or LABA in asthma. In this review, the mechanisms of action of LAMA in asthma were summarized and possible role of fixed dose ICS/LABA/ LAMA in asthma treatment was discussed under the light of current literature.
