[Efficacy of radiation synovectomy in degenerative inflammatory and chronic inflammatory joint diseases].

AIM: Effect of radiosynovectomy (RS) should be evaluated both by subjective and objective parameters in patients with osteoarthritis and in patients with inflammatory joint disorders not caused by rheumatoid arthritis. METHODS: A total of 98 joints in 61 patients were investigated. Patients were divided into two groups. The first group included 35 patients with therapy-resistant effusions caused by severe osteoarthritis (46 joints). The second group consisted of 26 patients (52 joints) with ankylosing spondylitis, reactive arthritis, undifferentiated spondylarthropathy, psoriatic arthritis, pigmented villo-nodular synovitis, and recurrent synovitis following surgery. Effect of RS was evaluated by a standardized questionnaire and quantified by T/B-ratios derived from blood pool images prior to and after RS. RESULTS: Within the first patient group suffering from osteoarthritis, 40% showed a good or excellent improvement of clinical symptoms, 51% were unchanged, and in 9% symptoms worsened. Similar results were found in the second patient group. The majority of unchanged results were small finger joints. In contrast, wrist and knee joints showed a better improvement. Good correlation between results of bone scan and patients subjective impression was found in 38% and 67% in the first and the second patient group, respectively. CONCLUSION: Radiosynovectomy might be an effective treatment in osteoarthritis and inflammatory joint disorders not caused by rheumatoid arthritis.

Predictive parameters of joint disease in DBA/1 transgenic mice.

We recently reported an accelerated onset of collagen-induced arthritis in DBAII mice overexpressing a T cell receptor Valpha11.1/Vbeta8.2 transgene as a preclinical animal model for age-associated T cell dysfunction. The accelerated onset is due to a transgenically sensitized T cell population that reacts to bovine type 11 collagen without prior in vivo sensitization. The model presents a readily observable distal joint phenotype that would allow preliminary aging and intervention studies to be evaluated by monitoring the presence or absence or degree of phenotypic expression of disease. In order to characterize clinical signs, we evaluated 69 transgenic mice in six different experiments for anticollagen antibody levels, and assigned each a modified arthritic score based on the degree of redness or swelling of the digital joints. We also correlated these parameters with signs of distress, including weight bearing, activity levels, and body posture. The average onset of disease was consistently within a 28 to 35-day period. The average arthritic score at the time of onset was 8. We found that none of the parameters predicted the onset of joint disease, but the modified scoring system reflected the severity of joint disease and predicted the degree of distress associated with the acute inflammation. The ability to determine the severity of joint disease by gross physical examination is a useful clinical feature because a numerical score is reflective of the degree of inflammation. Because the transgenic mouse model is a T cell-driven disease, the effect of aging on T cell activity can be monitored easily. In addition, the use of our modified arthritic scoring system makes it possible to conduct mouse experiments in a humane manner.

Calcium pyrophosphate in joint disease.

Shedding of crystals from cartilage into a joint space can cause pseudogout, the most common acute monarthritis in the elderly. The calcification may also be associated with structural change identical to osteoarthritis. Treatment seeks to reduce symptoms and improve function.
