Relationship Between Inflammation Parameters Which Are Obtained From Blood Count And Knee Osteophytes

Abstract

Objective:Osteoarthritis is no longer considered a degenerative disease. The presence of underlying low-grade inflammation has been well demonstrated. Although osteophytes are used to determining the radiological stage, the development mechanism is not fully understood. The aim of this study is to separately evaluate the relationship between various inflammation parameters associated with complete blood count with osteophytes and radiological stage. Methods:Patients who met the American College of Rheumatology clinical knee osteoarthritis criteria, retrospectively selected. Kellgren-Lawrence grading scale was used for disease severity and Osteoarthritis research society international grading was used for osteophyte size evolution. Red blood cell distribution width, platelet to lymphocyte ratio, neutrophil to lymphocyte ratio, neutrophil to monocyte ratio, lymphocyte to monocyte ratio, and mean platelet volume obtained from complete blood count, and C-reactive protein levels were recorded. The relationship between inflammation markers and osteophytes and disease stage was evaluated by logistic regression analysis. Results:A significant correlation was shown between CRP and PLR in the early stage of the disease. No correlation was found in the advanced stage. No correlation was found between osteophyte progression and inflammatory markers in the analysis based on osteophyte size Conclusion:In this study, we have shown that there is a relationship between systemic low-grade markers of inflammation and early stages of knee osteoarthritis, but this relationship was not detected in advanced stages. There was not a relation between osteophyte progression and these markers. Even though it seems to be running together, we can assume that the progression of the disease and osteophyte formation have different mechanisms.
