Abstract
Background: Asthma significantly impacts global health, necessitating effective management strategies. A combination of inhaled corticosteroids (ICSs) and long-acting β2-agonists (LABA) is recommended for patients with inadequately controlled asthma. Method: This prospective, open-label, multicenter study (PROMISING-SHIFT) study evaluated the safety and efficacy of once-daily [...] Read more.
Background: Asthma significantly impacts global health, necessitating effective management strategies. A combination of inhaled corticosteroids (ICSs) and long-acting β2-agonists (LABA) is recommended for patients with inadequately controlled asthma. Method: This prospective, open-label, multicenter study (PROMISING-SHIFT) study evaluated the safety and efficacy of once-daily Indacaterol/Mometasone (IND/MF) dry powder inhaler (DPI) in Indian asthma patients (≥12 years), inadequately controlled with prior therapies. Patients received IND/MF DPI in three strengths (150/80 mcg, 150/160 mcg, 150/320 mcg) over 12 weeks. Results: The study included a total of 174 participants, and 27 adverse events (AEs) in 25 patients (14.37%) were reported, primarily mild to moderate, with no serious adverse events (SAEs). Drug-related treatment-emergent adverse events (TEAEs) were observed in 11 patients. Significant improvements were noted in the mean trough FEV1 and FVC, increasing from baseline to week 4 and week 12 (p < 0.001). The mean ACQ-5 score significantly decreased from 3.0 ± 0.73 baseline to 2.50 ± 0.53 (16.67%) at week 4 and further to 1.73 ± 0.35 at week 12, along with reduced exacerbations (p < 0.001). The need for rescue medication declined from 13.79% to 8.62%, and 96.55% of patients reported treatment satisfaction by study completion. Conclusion: Once-daily IND/MF DPI demonstrated a favorable safety profile with marked improvements in lung function, asthma control, and patient satisfaction, making it a promising option for long-term asthma management in Indian patients.

Background: Information is limited regarding the role of impulse oscillometry (IOS) for the detection of preserved ratio impaired spirometry (PRISm). Therefore, we aimed to study the diagnostic ability of IOS in differentiating between PRISm and healthy subjects. Methods: This retrospective data collection was done at the Lung Health Center, Faculty of Medicine, Chiang Mai University, Thailand between July 2019 and April 2022. The potential diagnostic possibilities of difference in resistance at 5 Hz (R5) and resistance at 20 Hz (R20) (R5-R20) for PRISm detection were analyzed. Results: The prevalence of PRISm was higher when using the fixed ratio (FR) criteria (FEV1/FVC ≥0.7 with FEV1 < 80% of predicted value) compared to the lower limit of normal (LLN) criteria (FEV1/FVC ≥ LLN and FEV1 < LLN) (10.0% vs. 4.2%). The %prediction for R5-R20 provided an acceptable area under the curve (AUC) for PRISm, defined by the LLN and the FR criteria (AuROC = 0.75 (95%CI; 0.64, 0.85) and 0.72 (95%CI; 0.63, 0.81), respectively). The cut-off value of %predicted R5-R20 ≥120% resulted in the highest sensitivity and specificity for detecting PRISm. Conclusions: The %predicted of R5-R20 ≥ 120% showed an acceptable performance for PRISm detection and PRISm may be detected by IOS. Full article

Procalcitonin (PCT) is commonly used to evaluate the etiology and severity of pneumonia. PCT has been shown to be elevated at baseline in patients with obesity. The aim of this study is to determine if body mass index (BMI) has an influence on admission PCT level in patients admitted to the hospital with a diagnosis of pneumonia. We conducted a retrospective cohort study that encompassed patient visits to a tertiary care center from 2014 until September 2023. A total of 18,652 patients presented to the emergency department with a diagnosis of pneumonia. A total of 3659 were admitted to the floor, and 2246 were admitted to the MICU. Patients were grouped based on admission BMI into five categories. The Kruskal–Wallis test performed on patients admitted to the floor revealed a statistically significant difference in PCT levels among groups of different BMIs (H = 34.97, df = 4, p < 0.001). In patients admitted to the MICU, the Kruskal–Wallis test revealed a significant difference in PCT levels among groups of different BMIs (H = 32.92, df = 4, p < 0.001). BMI has a statistically significant effect on PCT in patients admitted to the hospital with pneumonia. Patients with higher BMI may exhibit less robust PCT levels, which may impact management decisions. Full article
