Some Beneficial Effects of Coenzyme Q10 Supplementation on Patients with Chronic Obstructive Pulmonary Disease

 Chronic inflammation, dyspnea and activity limitation are common phenomena in patients with chronic obstructive lung disease.  Clinical studies suggest that Ubiquinone has anti-inflammatory and energetic properties. Here the beneficial effect of CoQ10 in patients with COPD will be studied.

 Baesd on the census method, 90 patients with moderate to severe COPD were divided into two identical placebo and CoQ10 groups. High sensitive-C-reactive protein (hs-CRP), Forced Expiratory Volume in 1 second, numerical rating breathlessness scale and "the time to get exhausted" were evaluated and recorded at baseline and the end of the study. The CoQ10 group received 120 mg of CoQ10 supplement per day versus the placebo group who also received a placebo (identical in look, size and taste to pharmaceutical sample) and were followed for 6 weeks. Data were analyzed using t-test, and nonparametric statistical tests. Qualitative variables were assessed by chi-square or Fisher exact tests. 

 The study included 49(53.6%) women and 41(46.4%) men, collectively 90 patients with moderate to severe COPD. The mean age was 66.97±12.59 years in the placebo and 64.21±11.78 years in the CoQ10 group (p=0.30). Breathlessness scale was improved in CoQ10 group (p<0.001). hs-CRP significantly declined after intervention in the CoQ10 compared to  the placebo group (p<0.001).No serious side effects were observed as a result of CoQ10 consumption.

 Daily administration of CoQ10 in COPD patients increases hs-CRP and improves dyspnea and "the time to get exhausted” without side effect.
