January 17, 2006
Estrogen therapy initiated immediately following ovariectomy staves off the cartilage loss known to accompany menopause... Oestergaard S, et al. Presented at: 10th World Congress of the Osteoarthritis Research Society International (OARSI); December 8-11, 2005; Boston, Mass. Abstract P294.

Increases in the Synthesis and Degradation of CTX-II Biomarkers May Predict OA Progression
January 13, 2006
Biomarkers of type II collagen synthesis and degradation may predict rapid progression among patients with knee osteoarthritis... Garnero P, et al. Presented at: 10th World Congress of the Osteoarthritis Research Society International (OARSI); December  8-11, 2005; Boston, Mass. Abstract A6.

Active Shape Modeling May Help Predict Osteoarthritis Fast Progressors
January 10, 2006
A new pilot study shows that active shape modeling (ASM) can quantify the changes that occur in the femoral head during the course of osteoarthritis (OA), findings that suggest the diagnostic technique may help identify OA patients who are at high risk for rapid progression and require surgical intervention... Gregory JS, et al. Presented at: 10th World Congress of the Osteoarthritis Research Society International (OARSI); December 8-11, 2005: Boston, Massachusetts. Abstract P254.

New Study Suggests Raloxifene May Benefit Women with Knee Osteoarthritis
January 5, 2006
A recent study of women with knee osteoarthritis (OA) found that treatment with raloxifene resulted in a statistically significant decrease in the excretion of key markers of cartilage degradation, pointing to the potential curative effect of this agent and long-term improved outcomes for patients with knee OA... Daniluk S, et al. Presented at: 10th World Congress of the Osteoarthritis Research Society International (OARSI); December 8–11, 2005; Boston, Mass. Abstract P67.

Oral Calcitonin May Delay Onset of Joint Disease and Relieve Pain of OA
January 4, 2006
Although calcitonin is an established antiresorptive agent, new research suggests that it also has a role in chondroprotection and may help relieve symptoms accompanying joint disease... Sondergaard BC, et al. Presented at: 10th World Congress of the Osteoarthritis Research Society International (OARSI); December 8–11, 2005; Boston, Mass. Abstract P133.

Several Potential Biomarkers May Help Predict the Development of Osteoarthritis
January 3, 2006
Osteoarthritis (OA) has been found to be associated with changes in the serum proteins implicated in matrix degradation, cellular activation, and inflammation—changes that can occur years before radiographic detection of the disease... Ling SM, et al. Presented at: 10th World Congress of the Osteoarthritis Research Society International (OARSI); December 8–11, 2005; Boston, Mass. Abstract P51.

Research Outlines Novel Role of IL-1, IGF-1 in Cartilage Damage of Arthritis
December 20, 2005
A new study by Dutch investigators suggests that interleukin-1 (IL-1)-induced suppression of cytokine signaling (SOCS) 3 renders chondrocytes insensitive to insulin-like growth factor-1 (IGF-1), a novel mechanism that appears to contribute to cartilage damage in arthritis...Van der Loo FAJ, et al.
