title: [Slow-acting anti-rheumatic agents: recent developments].
abstract: Until recently, treatment of osteoarthritis targeted the pain and the disability of the involved joints. It consisted in a mix of analgesics, anti-inflammatory drugs, steroid infiltrations and physical therapies. Usefulness of slow but long acting substances is increasing not only by their action on the symptoms but also because they positively influence the evolution of the disease. Some of them seem to induce a structural effect on the cartilage confirmed by a slow down of the joint space narrowing on successive radiographs of the knees. Presently, only basic matricial precursors such as chondroitin sulfate, glucosamine sulfate and hyaluronic acid are available in the clinic. They act by reducing cartilage destruction and enhancing chondrocyte anabolism. These preliminary results should be confirmed by further studies based on magnetic resonance imaging and surrogate markers of the cartilage matrix. Recent developments in the understanding of the physiopathology of osteoarthritis, including the key role of some cytokines, should allow new therapic ways, individually or in combination.
