The benefits of long-term systemic antimicrobial therapy in chronic obstructive pulmonary disease
Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are major contributors to the morbidity and mortality associated with this disease. Current approaches that likely reduce chronic obstructive pulmonary disease (COPD) exacerbations include smoking cessation, influenza and pneumococcal vaccinations, long-acting bronchodilator and inhaled corticosteroid therapy, pulmonary rehabilitation, and mucolytic drugs. However, with optimal treatment using all of these modalities, we are only able to reduce exacerbations by about 40%. A significant proportion of COPD exacerbations are bacterial, therefore long-term antimicrobial therapy could have a role in preventing exacerbations. Long-term antibiotic treatment in COPD regimens that are being evaluated include low-dose macrolide therapy, pulsed fluoroquinolone administration and the use of inhaled antibiotics. Although initial results have been promising with significant reductions in exacerbations with these regimens, additional studies are required to identify the appropriate patient and regimen and elucidate the risk–benefit as well as cost effectiveness of long-term antibiotics in COPD

Obesity, inflammatory and thrombotic markers, and major clinical outcomes in critically ill patients with COVID‐19 in the US
Objective
This study aimed to determine whether obesity is independently associated with major adverse clinical outcomes and inflammatory and thrombotic markers in critically ill patients with COVID‐19.
Methods
The primary outcome was in‐hospital mortality in adults with COVID‐19 admitted to intensive care units across the US. Secondary outcomes were acute respiratory distress syndrome (ARDS), acute kidney injury requiring renal replacement therapy (AKI‐RRT), thrombotic events, and seven blood markers of inflammation and thrombosis. Unadjusted and multivariable‐adjusted models were used.
Results
Among the 4,908 study patients, mean (SD) age was 60.9 (14.7) years, 3,095 (62.8%) were male, and 2,552 (52.0%) had obesity. In multivariable models, BMI was not associated with mortality. Higher BMI beginning at 25 kg/m2 was associated with a greater risk of ARDS and AKI‐RRT but not thrombosis. There was no clinically significant association between BMI and inflammatory or thrombotic markers.
Conclusions
In critically ill patients with COVID‐19, higher BMI was not associated with death or thrombotic events but was associated with a greater risk of ARDS and AKI‐RRT. The lack of an association between BMI and circulating biomarkers calls into question the paradigm that obesity contributes to poor outcomes in critically ill patients with COVID‐19 by upregulating systemic inflammatory and prothrombotic pathways
