Comarum Palustre in Knee Osteoarthritis and Diabetes

Phase 4
Completed
Conditions
Osteoarthritis
Diabetes Mellitus
Interventions
Drug: Comarum Palustre
Registration Number
NCT03530930
Lead Sponsor
Federal State Budgetary Scientific Institution, Research Institute of Fundamental and Clinical Immunology
Brief Summary

The study evaluates analgesic, antiinflammatory and metabolic effects of Comarum palustre in patients with knee osteoarthritis (OA) and diabetes mellitus. Patients with osteoarthritis will receive Comarum palustre together with conventional treatment of osteoarthritis and diabetes.

Detailed Description

Comarum palustre have been shown to exert analgesic properties in patients with knee osteoarthritis not responding to diclofenac. In animal models comarum palustre showed anti-inflammatory, immunomodulatory, analgesic, antioxidant, antihistamine, and membrane-stabilizing effects. Thus, pleiotropic properties of Comarum Palustre may provide a rationale for this use in patients having both osteoarthritis and diabetes mellitus. In this group of patients Comarum Palustre may not only relieve OA-related pain but reduce systemic inflammation, decrease progression of atherosclerosis and diabetes complications.

Primary Outcome Measures
NameTimeMethod
Change From Baseline in Visual Analogue Scale for PainBaseline, 4 weeks

The Visual Analogue Scale for Pain varies from 0 to 10 cm. Higher values represent worse outcomes.

Secondary Outcome Measures
NameTimeMethod
Changes in neopterin levelsBaseline, 4 weeks

serum neopterin measured in nmol/L

Knee injury and Osteoarthritis Outcome Score (KOOS) - subscale Activities of daily living (ADL)Baseline, 4 weeks

KOOS ADL consists of 17 items, which are answered on a 4-point likert scale (0=no problems, 4=extreme problems). Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems.

Quality of life with the The Short Form (36) Health Survey scoreBaseline, 4 weeks

The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section.Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.

Changes in serum levels of aggrecanBaseline, 4 weeks

serum levels of aggrecan measured in ng/ml

Knee injury and Osteoarthritis Outcome Score (KOOS) - subscale PainBaseline, 4 weeks

KOOS Pain consists of 9 items, which are answered on a 4-point likert scale (0=no problems, 4=extreme problems). Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems.

Knee injury and Osteoarthritis Outcome Score (KOOS) - subscale SymptomsBaseline, 4 weeks

KOOS Symptoms consists of 7 items, which are answered on a 4-point likert scale (0=no problems, 4=extreme problems). Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems.

Intermittent and Constant Osteoarthritis Pain self-report questionnaireBaseline, 4 weeks

Pain measure: Scale range 0-100 with higher scores indicating worse pain

Changes in serum levels of antibodies to collagen type IIBaseline, 4 weeks

serum levels of antibodies to collagen type II measured AU/ml

Changes in serum levels of C-reactive proteinBaseline, 4 weeks

serum levels of C-reactive protein (CRP), g/l

Changes in histamine levelsBaseline, 4 weeks

serum levels of histamine in ng/ml

Changes in inflammation biomarkersBaseline, 4 weeks

serum levels of (CRP), interleukin (IL)-6, IL- 18, adiponectin, IL-10, and interferon (IFN) γ in pg/ml

changes in diabetes controlBaseline, 4 weeks

Glycated haemoglobin (HbA1c)

Changes in depression scores measured with Patient Health Questionnaire-9 (PHQ9P)Baseline, 4 weeks

The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and measuring the severity of depression. It consists of nine questions with responses ranging from "0" (not at all) to "3" (nearly every day). The possible range is 0-27. Higher values represent worse outcome.

Changes in lipid biomarkersBaseline, 4 weeks

serum total cholesterol, HDL, and LDL measured in mmol/L

Patient global assessment of osteoarthritisBaseline, 4 weeks

The Visual Analogue Scale for the Patient global assessment of osteoarthritis varies from 0 to 10 cm. Higher values represent worse outcomes.
