甲状旁腺激素及其受体与骨关节炎的关系研究进展

骨关节炎是一种以关节软骨破坏、软骨下骨的硬化和滑膜反应为特征的慢性疾病.目前发现甲状旁腺激素(Parathyroid hormone,PTH)能够抑制骨关节炎患者软骨细胞终末期成熟分化,有明显软骨保护、延缓骨关节炎进展的作用.通过研究PTH、PTHR与骨关节炎的关系,对骨关节炎治疗及预后将起到重要的指导作用.     

Long-term results of the subtubercle tibial osteotomy using the circular external fixator for medı̇al compartment osteoarthrı̇tı̇s of knee

BackgroundWe evaluated the long-term clinical and radiographic outcomes of patients who underwent subtubercular tibial osteotomy (STO) with Ilizarov external fixation used for high tibial osteotomy for medial knee osteoarthritis (MKOA).MethodsBetween October 2003 and December 2011, 42 knees of 40 patients who had undergone STO with Ilizarov external fixator with a diagnosis of MKOA were evaluated. Survival analysis was performed by examining the duration of total knee arthroplasty (TKA). Clinical and radiological variables were collected at the time of admission after removal of the fixator and at outpatient follow up.ResultsMean age was 49.3 ± 5.68 (range 37–61) years, mean postoperative follow up time was 14.22 ± 2.93 (range 9–18) years, and mean fixator duration was 14.6 (range 13–20) weeks. Survival analysis showed 100% at 5 years, 95.2% at 10 years and 88.1% at 15 years. Clinical examination of the patients showed significant improvement in American Knee Society score (KSS), KSS functional score and Oxford Knee Score (OKS) score (P = 0.005). In the study, it was observed that the patients' knee osteoarthritis had progressed over time. On examination, radiographic measurements including mechanical axis deviation, medial proximal tibial angle, femorotibial angle, and joint line alignment angle improved significantly after deformity correction (P = 0.001).ConclusionSTO using the Ilizarov method offers long-term survival. It provides effective treatment in young patients with isolated MKOA. Achieving the desired amount of correction in the coronal and sagittal planes can be presented as a surgical technique for the treatment of MKOA as an effective method in clinical and radiological correction.

Melatonin: A novel candidate for the treatment of osteoarthritis

Osteoarthritis (OA), characterized by cartilage erosion, synovium inflammation, and subchondral bone remodeling, is a common joint degenerative disease worldwide. OA pathogenesis is regulated by multiple predisposing factors, including imbalanced matrix metabolism, aberrant inflammatory response, and excessive oxidative stress. Moreover, melatonin has been implicated in development of several degenerative disorders owing to its potent biological functions. With regards to OA, melatonin reportedly promotes synthesis of cartilage matrix, inhibition of chondrocyte apoptosis, attenuation of inflammatory response, and suppression of matrix degradation by regulating the TGF-β, MAPK, or NF-κB signaling pathways. Notably, melatonin has been associated with amelioration of oxidative damage by restoring the OA-impaired intracellular antioxidant defense system in articular cartilage. Findings from preliminary application of melatonin or melatonin-loaded biomaterials in animal models have affirmed its potential anti-arthritic effects. Herein, we summarize the anti-arthritic effects of melatonin on OA cartilage and demonstrate that melatonin has potential therapeutic efficacy in treating OA.

Chondroprotective effects of the combination chondroitin sulfate-glucosamine in a model of osteoarthritis induced by anterior cruciate ligament transection in ovariectomised rats

ContextThe efficacy of the combination chondroitin sulfate-glucosamine (CS-GlcN) in the treatment of knee osteoarthritis (OA) has been suggested in recent clinical studies. In vitro reports have also suggested anti-inflammatory and anti-resorptive effects of this combination.ObjectiveThe aim of this study was to characterize the effects of CS-GlcN on joint degradation in vivo including the assessment of inflammation and bone metabolism in a model of OA.Materials and methodsWe have used the OA model induced by anterior cruciate ligament transection (ACLT) in ovariectomised rats. CS-GlcN was administered daily (oral gavage) from week 0 until week 12 after ovariectomy at the dose of 140 (CS) + 175 (GlcN)(HCl) mg/kg. Histochemical analyses were performed, the levels of biomarkers and inflammatory mediators were measured by luminex or ELISA and bone microstructure was determined by μCT.ResultsCS-GlcN protected against cartilage degradation and reduced the levels of inflammatory mediators such as interleukin-1β and tumor necrosis factor-α in the affected knee. In addition, serum biomarkers of inflammation and cartilage and bone degradation including matrix metalloproteinase-3, C-telopeptide of type II collagen and the ratio receptor activator of nuclear factor κB ligand/osteoprotegerin were significantly decreased by CS-GlcN. This treatment also tended to improve some bone microstructural parameters without reaching statistical significance.Discussion and conclusionsThese results demonstrate the chondroprotective effects of CS-GlcN in vivo, in the experimental model of ACLT in ovariectomised rats, and suggest that this combination may be useful to control the joint catabolic effects of inflammatory stress. These findings could have clinical relevance related to the prevention of joint degradation by CS-GlcN and support the potential development of OA treatments based on this combination.
