Plain English Summary

Background and study aims
Dyslipidemia, an imbalance of fats in the blood, is one of the most common modifiable risk factors for cardiovascular disease, in which statins are recommended as first-line pharmacological therapy. Treatment with statins reduces the risk of heart attack and stroke in most patients with elevated low-density lipoprotein (LDL) cholesterol levels and in most high-risk patients with atherosclerotic cardiovascular disease. Statins are well tolerated in most adult patients with a low incidence of minor adverse effects. However, they are associated with various side effects on skeletal muscle - from mild to severe. The mechanism of statin-associated muscle symptoms (SAMS) is currently unclear, but changes in blood coenzyme Q10 (CoQ10) levels may be involved in the pathological process. CoQ10 is an intracellular antioxidant that protects membrane phospholipids, mitochondrial membrane proteins, and LDL particles from oxidative damage caused by free radicals. Statins, by their inhibitory effect on the cholesterol synthesis pathway, can reduce not only cholesterol synthesis but also the synthesis of other molecules that arise from mevalonate, including CoQ10. Pycnogenol® is a standardized pine bark extract of Pinus pinaster Aiton and shows different effects in humans after oral administration, e.g. antioxidant, anti-inflammatory, antiallergic, hypolipidemic etc., which have been demonstrated in many clinical studies. The aim of this study is to investigate how 3 months of daily administration of Pycnogenol® (150 mg/day) by patients treated with statins affect CoQ10 levels in the blood, the serum lipid balance, LDL and high-density lipoprotein (HDL) subfraction levels, lipoprotein (a) (Lp(A)) and apolipoprotein-A1 (Apo-A1) levels, level of oxidative stress, the antioxidant status of the patients and adverse effects of statins related to muscles – weakness, pain, tiredness.

Who can participate?
Adults aged 19 to 60 years who are being treated for the first time with statins

What does the study involve?
In this study, the effects of Pycnogenol® (PYC- group) on the status of patients with dyslipidemia, who are treated with statins for the first time will be compared with placebo (PL-group). Patients who meet the inclusion criteria, after initial medical investigation (complete medical history and examination, questionnaire about quality of life) will be allocated to one of the two arms of the project (PYC or PL-group) in a ratio of 1:1, according to a computer-generated random sequence (visit 1). The randomisation will be performed by a statistician, who will have no contact with the participants. Patients will be administered 150 mg Pycnogenol® or Placebo for 3 months. After the intervention period, patients will be examined by the doctor and patients will fill out a questionnaire about quality of life (visit 2). At both visits, blood samples will be taken. The research team and participants will be unaware of the group assignments.

What are the possible benefits and risks of participating?
Participants who receive Pycnogenol® may benefit from the improvement of statin-associated muscle symptoms, quality of life and antioxidant status. There are no known risks to participants taking part in this study.

Study hypothesisThe aim of the study is to investigate how the oral administration of Pycnogenol® (150 mg/day) by patients treated with statins affects coenzyme Q10 (CoQ10) levels in the blood, the serum lipid profile, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) subfractions, lipoprotein (a) (Lp(A)) and apolipoprotein-A1 (Apo-A1) levels, level of oxidative stress and antioxidant status of the patients and adverse effects of statins related to muscles – weakness, pain, tiredness.
Ethics approval(s)Approved 24/10/2022, Ethics Committee of Faculty of Medicine, Comenius University and University Hospital in Bratislava (Old Town Hospital, Mickiewiczova 13, 81369 Bratislava, Slovakia; +421 2 57 290 495; jan.pecenak@sm.unb.sk), ref: 69/2022
ConditionPatients treated with statins for the first time
InterventionThe randomization will be performed by a statistician, who will have no contact with the participants. The research team and participants will be unaware of the group assignments and the envelope with assignments will be opened only after analyses are finished and databases are completed and locked.

Participants randomised into active or placebo groups will be required to take three capsules a day for 3 months:
1. Active intervention: 50 mg of a standardised extract from pine bark – Pycnogenol® per capsule
2. Placebo intervention: maltodextrin without the active substances, identically packaged as active.
Both interventions will be prepared by Horphag Research Ltd. (Geneva, Switzerland).

As part of the project, patients make two visits to the doctor, they will be examined, blood will be taken and a quality of life questionnaire will be undertaken.
