The Disease-Modifying Effects of Hyaluronan in the Osteoarthritic Disease State
نویسندگان
چکیده
Hyaluronic acid (HA) has been a treatment modality for patients with knee osteoarthritis (OA) for many years now. Since HA was first introduced for the treatment of painful knee OA, much has been elucidated regarding both the etiology of this disease and the mechanisms by which HA may mitigate joint pain and tissue destruction. The objectives of this article are to (1) describe the etiology and pathophysiology of OA including both what is known about the genetics and biochemistry, (2) describe the role of HA on disease progression, (3) detail the antinociceptive and anti-inflammatory actions of HA in OA, and (4) present evidence of disease-modifying effects of HA in the preservation and restoration of the extracellular matrix. These data support that HA is not only just a simple device used for viscosupplementation but also a biologically active molecule that can affect the physiology of articular cartilage.

Hyaluronan inhibits expression of ADAMTS4 (aggrecanase-1) in human osteoarthritic chondrocytes
BACKGROUND Intra-articular injection of hyaluronan (HA) has been suggested to have a disease-modifying effect in osteoarthritis, but little is known about the possible mechanisms. OBJECTIVE To investigate the effects of HA species of different molecular mass, including 800 kDa (HA800) and 2700 kDa (HA2700), on the expression of aggrecanases (ie, ADAMTS species), which play a key role in aggre...
متن کاملNon-adherence to Disease-Modifying Treatments in Patients with Multiple Sclerosis
Background: Multiple Sclerosis (MS) is a debilitating disease of the central nervous system. Usually, long-term MS medications are injected intramuscularly or subcutaneously, making them intolerable for many MS patients. Objectives: In the present study, the rate and the causes of non-adherence to MS disease-modifying drugs (DMDs) were assessed in patients with MS. Materials and Methods: Two ...
متن کاملPositive side effects of Ca antagonists for osteoarthritic joints—results of an in vivo pilot study
BACKGROUND We have shown previously that some calcium antagonists inhibit hyaluronan export, loss of proteoglycans, and degradation of collagen from osteoarthritic cartilage. Clinically approved calcium antagonists normally are prescribed for cardiac arrhythmia. In the present study, we compared the effect of these drugs on osteoarthritic patients which had received no medication and patients w...

Rheumatoid arthritis is a chronic systemic inflammatory disease that affects approximately 0.5-1% of the world population. The current approach to this disease is to start an intensive treatment without delay once the disease has developed. Various studies in the literature have shown that combination of disease modifying antirheumatic drugs such as sulfasalazine and chloroquine offers a more a...
