Determination of Adipocytokine in Synovial Fluid of Osteoarthritis Patients

Brief Summary:
The purpose of this study is to determine the concentration of different adipocytokine (adiponectin, leptin, resistin, visfatin, osteopontin) and an inflammation classic markers as Interleukine 1 beta, tumor necrosis alfa, interleukine 6 and high sensibility reactive c protein in the synovial fluid of knee osteoarthritis patients, and compare with the inflammation detected with ultrasonography evaluation of the joint. In last years, some studies appeared focusing on the role of adipocytokines in osteoarthritis and they correlated adipocytokines with cartilage degradation and x-ray degree; in our study we will focused in the importance of adipocytokines in the inflammatory changes more than in joint destruction.

Group/Cohort Intervention/treatment
Inflammatory knee osteoarthritis
We recruited patients with osteoarthritis and synovial effusion to diagnostic the effusion and to confirm that this this synovial fluid had mechanical characteristics. Now we are going to determine the adipocytokines and traditional parameters of inflammation in this synovial fluid to correlate it, and we will associate it with the ultrasound explanation of the knee that we have in our database.
Other: arthrocentesis
The made a diagnostic arthrocentesis to all patient we included

Other: ultrasonography of the knee
We explored the affected knee with an ultrasound explanation in order to describe inflammatory changes based on standard examination.

Primary Outcome Measures :
  1. Determination of adipocytokine levels (adiponectin, leptin, resistin, visfatin, osteopontin) in synovial fluid [ Time Frame: We determine adipocytoquines in one month, all patients in the same determination kit ]
    We have all the synovial fluid freeze, so now we have to determine the levels of everyone.

Secondary Outcome Measures :
  1. Knee inflammation parameters detected by ultrasonography [ Time Frame: three months ]
    We performed the ultrasonography evaluation at the same time than the visit were realized, and we have the results in a data base, so we will wait for the adipocytokine results and we will compare with ultrasound evaluation

  2. To determine additional classic parameters of inflammation in synovial fluid as Interleukine 1 beta, Interleukine 6 and tumor necrosis factor alfa [ Time Frame: We determine this inflammatory parameters in one month in all patient at the same time ]
    We will use classic inflammation parameters to compare with adipocytokine levels

Sampling Method:   Probability Sample
Study Population
Patient with knee osteoarthritis and synovial effusion who attende to a Rheumatologist unit for this problem. We made the visit and anonimously we kept the results of examination and ultrasonography in our database and we freezed synovial fluid. Now we will determine the adipocytokines and classic inflammatory parameters in this synovial fluid

Inclusion Criteria:

  • aged 50 to 81
  • primary osteoarthritis of the knee
  • synovial effusion in examination
  • patient who have the results in our database

Exclusion Criteria:

  • any other rheumatic conditions as rheumatoid arthritis or another inflammatory disease
  • secondary knee osteoarthritis
  • history of knee surgery
  • any conditions that at investigator criteria exclude the patient from study procedures
