| Abstract |
| Abstract We analyzed the levels of endotoxin and #-d-glucan, which possibly induce cytokine production, in the synovial fluid of patients on long-term hemodialysis and compared the results to those in patients with osteoarthritis and rheumatoid arthritis. We studied 42 knees in 42 hemodialysis patients, 21 in 21 osteoarthritis patients, and 26 in 26 rheumatoid arthritis patients. The mean ages were 60.7, 63.2, and 59.7 years, respectively. The duration of hemodialysis in the long-term hemodialysis group averaged 14.0 years. The concentrations of endotoxin and #-d-glucan in the synovial fluid of these three groups were measured. The concentration of endotoxin was the same in the three groups. However, the concentration of #-d-glucan was significantly higher in long-term hemodialysis patients. This finding suggests that #-d-glucan may have some relation to the pathogenesis of the synovitis which exists in the hydrarthrosis of long-term hemodialysis patients. |
