  • Research summary

    Summary of Research

    An investigation of bodyfluids in patients suffering with joint problems. Bodyfluids will be analysed for bodily biproducts which are potentially elevated in these scenarios. Novels methods of analysing these body fluids will be employed, hopefully yielding new results.

    Computer analysis will then attempt to correlate the findings of the analysis with joint conditions. Any targets will be highlighted for further study

    Summary of Results

    This project was a pilot study investigating which small molecules are contained in joint fluid and which may be important in joint disease, infection and joint lubrication.
    Joint fluid has been rarely analysed using this technique. Therefore, the first step was to ensure that our methods were safe and robust. Furthermore, we wanted to ensure that the results would be reliable and valid. We wanted to ensure that we were not introducing any contaminants and that we could be confident of the results.
    We were able to demonstrate that the handling and analysis of the joint did not unduly affect the results, and where the results were affected by storage we understood what those affects were and could consider this when interpreting the results. We also demonstrated that our methods were appropriate to successfully analyse the human joint fluid.
    We compared the joint fluid originating from hips and knees. We found significant differences in the metabolism of the fluid that came from osteoarthritis in hips and knees. We detailed these differences and presumed these were due to mechanical differences between the joints, one being a ball and socket joint and the other a hinge. This means the mechanical stresses on the fluids are different, perhaps effecting the fluid directly.
    We reported the changes in metabolism that take place when joint fluid harbours an infection. The presence of infection is destructive to any joint. Therefore, being able to detect it early can give better outcomes for patients. We reported a host of metabolites that are affected when infection occurs, with the potential of using this information to analyse joint fluid for infection in the future.
    We looked at the lubrication properties of joint fluid. We looked for components of the fluid that seem to be related to good lubrication. Our hope is that by knowing which components are important, this information could be used to give better survival to joints in the future.
