Identification of Response to Hypertonic Dextrose Prolotherapy Markers in Knee Osteoarthritis Patients by Cytokine Array

Identification of Early Response to Hypertonic Dextrose Prolotherapy Markers in Knee Osteoarthritis Patients by an Inflammation-related Cytokine Array

Hypertonic dextrose prolotherapy has been used in knee osteoarthritis (OA) clinically for a long time. However the study about the mechanism is scant. The question of biomarkers of knee OA cartilage response to hypertonic dextrose prolotherapy remains currently unresolved. On this basis, the aim of this study was to characterize the secreted protein factors behind the inflammatory potential involving the hypertonic dextrose prolotherapy of knee OA. 10~12 older than 65 years old knee OA patients will be recruited for clinical Western Ontario McMaster University Osteoarthritis (WOMAC) index, knee X ray evaluation and knee joint synovial fluid analysis before and after hypertonic dextrose prolotherapy. The expressions of inflammatory factors will be measured by a novel cytokine antibody array methodology. The study will evaluate inflammation-related cytokines in patients of knee joint synovial fluid. Human Cytokine Antibody Array that allows profiling synovial fluid production of anti and pro-inflammatory cytokines simultaneously. Altered levels of cytokine from the array membranes incubated with tissue lysates will quantitatively depict as a histogram for relative cytokine induction or reduction in the synovial fluid. The cytokines messenger ribonucleic acid levels will be quantified by quantitative reverse-transcription polymerase chain reaction and proteins expression was analyzed by Enzyme-Linked ImmunoSorbent Assay. The WOMAC Index, minimum joint space width, and Human Cytokine Antibody Array between before and after interventions will be compared. Differences between groups will be determined by the Mann-Whitney U test. For the synovial angiogenesis is accompanied with inflammatory feature in knee OA, associations between endothelial growth factor (VEGF) expression and VEGF isoforms pattern will be determined with the Spearman correlation.
