Sex differences in the relationship between individual systemic markers of inflammation and pain in knee osteoarthritis.

ABSTRACT:

Objective

There are suggestions that the relationship between inflammation and pain in osteoarthritis (OA) may differ by sex, yet studies have been limited. We investigated whether the relationship between knee-specific OA pain and systemic inflammatory markers differs by sex.

Design

196 patients scheduled for knee arthroplasty for OA were included. Questionnaires were completed and blood samples drawn pre-surgery. Questionnaire data: knee pain (WOMAC), sex, age, height, weight, comorbidities, depressive symptoms, and symptomatic joint count. Systemic inflammatory markers (cytokines IL-6, IL-8, IL-10, IL-1β and TNF-α) were measured by multiplex ELISA. A series of regression models with interaction terms between sex and ln-transformed inflammatory markers were estimated with pain score as the outcome. The adjusted relationship between pain and inflammatory markers, by sex, were presented graphically.

Results

Mean age was 64 years (range 43-89); females comprised 58.7% of the sample. In adjusted analyses, similar relationships between knee pain and lnIL-10 (negative: β = -1.28, 95%CI (-1.97, -0.58)) and lnTNF-α (positive: β = 0.92, 95%CI (0.11, 1.76)) were found for females and males. In contrast, relationships between knee pain and lnIL-1β, lnIL-6 and lnIL-8 differed in direction for females and males. Specifically, for lnIL-1β and lnIL-8 they were positive for males, negative for females. The opposite was found with lnIL-6, negative for males, positive for females.

Conclusion

These findings provide some evidence of sex-specific relationships between individual inflammatory markers and knee OA pain. They expose a need for further exploration of sex-differences in this context, with potential future implications for treatment or drug development in OA.

Project description:Leveraging the unique conditions of space microgravity, our research offers groundbreaking insights into osteoarthritis (OA), a degenerative joint disease impacting over three million Canadians and predominantly affecting load-bearing joints such as the knee. With knee OA (KOA) known for its higher incidence and severity among females—a phenomenon not fully explained by existing risk factors—the application of simulated microgravity (SMG) presents a novel approach to understanding the disease's progression and the biological sex differences in response to it. By employing rotating wall vessel (RWV) technology to simulate spaceflight conditions on Earth, our studies focus on the biomechanical unloading experienced in microgravity, which has been observed to induce OA-like changes in articular tissues. This innovative research strategy allows us to explore the potential mechanisms of OA development and progression in a controlled environment, mimicking the microgravity of space to provide new perspectives on the disease's molecular underpinnings. Initial results from our investigations reveal that SMG significantly alters the molecular expression profiles in engineered meniscus constructs derived from non-KOA patients, notably influencing genes related to chondrocyte hypertrophy and OA progression while downregulating protective genes. Further analysis has illuminated sex-specific molecular responses to SMG, demonstrating pronounced differences between male and female specimens. This highlights the importance of considering biological sex in OA research, as it significantly influences disease development and response to microgravity conditions. Extended RNA sequencing under SMG conditions has identified distinct molecular signatures for different sex-based groups, pointing towards an OA-like transcriptome profile in females particularly responsive to SMG. One of the most significant findings from our microgravity studies is the modulation of CD36, a transmembrane protein implicated in lipid metabolism and OA pathogenesis. Its altered expression under SMG conditions and known upregulation in KOA patients underscore the potential mechanisms by which microgravity-induced cellular responses can mimic and inform us about OA development, particularly in terms of sex-specific disparities.
