Reduction of serum cholesterol levels with statin therapy decreases the risk of coronary heart disease. Inhibition of HMG-CoA reductase by statin results in decreased synthesis of cholesterol and other products downstream of mevalonate, which may produce adverse effects in statin therapy. We studied the reductions of serum ubiquinol-10 and ubiquinone-10 levels in hypercholesterolemic patients treated with atorvastatin. Fourteen patients were treated with 10 mg/day of atorvastatin, and serum lipid, ubiquinol-10 and ubiquinone-10 levels were measured before and after 8 weeks of treatment. Serum total cholesterol and LDL-cholesterol levels decreased significantly. All patients showed definite reductions of serum ubiquinol-10 and ubiquinone-10 levels, and mean levels of serum ubiquinol-10 and ubiquinone-10 levels decreased significantly from 0.81 ± ± ± ± ± 0.21 to 0.46 ± ± ± ± ± 0.10 µ µ µ µ µg/ml (p < 0.0001), and from 0.10 ± ± ± ± ± 0.06 to 0.06 ± ± ± ± ± 0.02 µ µ µ µ µg/ml (p = 0.0008), respectively. Percent reductions of ubiquinol-10 and those of total cholesterol showed a positive correlation (r = 0.627, p = 0.0165). As atorvastatin reduces serum ubiquinol-10 as well as serum cholesterol levels in all patients, it is imperative that physicians are forewarned about the risks associated with ubiquinol-10 depletion.

The increased production of IL-4, IL-10, and RANTES in the airway may play an important role in the pathophysiological mechanisms of RSV infection.

From the long-term observation of this patient, we propose that LPL deficiency is not invariably associated with high mortality and that even with repeated episodes of acute pancreatitis, pancreatic function may be slow to decline.

Although yearly fluctuations have been observed, the introduction of vaccination significantly decreased pediatric RVGE hospitalizations and outpatient visits, especially in the age group eligible for vaccination. During the second and third year of subsidization, we observed a herd protection effect on other age groups <5 y who were not eligible for vaccination. Clinicaltrial.gov.registered#:NCT01733862.
