Pycnogenol (maritime pine bark extract) in osteoarthritis

1. It is possible to detect constituents and/or metabolites of Pycnogenol in serum, blood cells and synovial fluid of patients after ingestion of the extract 2. Constituents and/or metabolites of Pycnogenol influence inflammatory and cartilage metabolism markers in osteoarthritis patients

Interventions

Patients were randomized into two groups using a computer-generated randomization list which was not accessible to the physicians and nurses who were involved in the patient care and management. Half
during the intake, approximately 1-2 days before the surgery (V2)
and during or shortly before knee surgery (V3), about 12 h after the last dose of Pycnogenol®. On the day of the surgery residual knee cartilage and synovial fluid were also collected. There was no fu

Design outcomes

Primary

MeasureTime frame
Detection and quantification of constituents and/or metabolites of Pycnogenol in serum, blood cells (before and after intake of Pycnogenol; V1, V2, V3) and synovial fluid (at the time of knee surgery, V3) of patients.

Secondary

MeasureTime frame
Measurement of markers of inflammation and cartilage metabolism in the patient's serum, blood cells (before and after intake of Pycnogenol; V1, V2, V3) and synovial fluid (at the time of knee surgery, V3) of patients, e.g. MMP-3, MMP-13, IL-1ß, ADAMTS-5.
