Abstract
INTRODUCTION
Severe and acute exacerbation of chronic obstructive pulmonary disease (COPD) is associated with a high mortality. Since COPD is an airway inflammatory disease, and heparin has shown anti-inflammatory effects in previous studies, we evaluated the clinical effect of low molecular weight heparin (LMWH; nadroparin) in COPD patients admitted into the hospital due to acute exacerbations.
METHODS
Sixty-six patients admitted to the intensive care unit (ICU) were randomly divided into control group (n = 33) and LMWH group (n = 33). The control group received conventional treatment, including oxygen therapy (non-invasive or conventional mechanical ventilation), anti-infection, atomization expectorant, spasmolysis, anti-asthmatics, and nutritional support. The LMWH group received the same treatment plus LMWH for 1 week. The levels of plasma C-reactive protein, interleukin-6, and fibrinogen were measured. The main outcomes were duration of mechanical ventilation, length of ICU stay, and hospital stay.
RESULTS
There were no significant differences between the groups with respect to demographics, severity of illness, and gas exchange variables. The levels of plasma C-reactive protein, interleukin-6, and fibrinogen were significantly decreased in the LMWH group. LMWH significantly reduced the mean duration of mechanical ventilation (6.6 days vs. 3.8 days; p < 0.01), the length of ICU stay (8.5 days vs. 5.6 days; p < 0.01) and hospital stay (14.3 days vs. 11.3 days; p < 0.01).
CONCLUSIONS
The addition of LMWH to standard therapy benefits COPD patients with acute exacerbation.
