Abstract
Systemic application of glucocorticoids is an essential anti-inflammatory and immune-modulating therapy for severe inflammatory or autoimmunity conditions. However, its long-term effects on articular cartilage of patients' health need to be further investigated. In this study, we studied the effects of dexamethasone (Dex) on the homeostasis of articular cartilage and the progress of destabilization of medial meniscus (DMM)-induced osteoarthritis (OA) in adult mice. Long-term administration of Dex aggravates the proteoglycan loss of articular cartilage and drastically accelerates cartilage degeneration under surgically induced OA conditions. In addition, Dex increases calcium content in calcified cartilage layer of mice and the samples from OA patients with a history of long-term Dex treatment. Moreover, long term usage of Dex results in decrease subchondral bone mass and bone density. Further studies showed that Dex leads to calcification of extracellular matrix of chondrocytes partially through activation of AKT, as well as promotes apoptosis of chondrocytes in calcified cartilage layer. Besides, Dex weakens the stress-response autophagy with the passage of time. Taken together, our data indicate that long-term application of Dex may predispose patients to OA and or even accelerate the OA disease progression development of OA patients.

Long-Term Exposure to Temozolomide Affects Locomotor Activity and Cartilage Structure of Elderly Experimental Rats. Biomedicines 2020; 8:biomedicines8120541. [PMID: 33255948 PMCID: PMC7760849 DOI: 10.3390/biomedicines8120541] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2020] [Revised: 11/16/2020] [Accepted: 11/24/2020] [Indexed: 11/16/2022] Open
Abstract
Chemotherapy with temozolomide (TMZ) is an essential part of anticancer therapy of various malignant tumours; however, its long-term effects on patients’ health and life quality need to be further investigated. Here, we studied the effects of TMZ and/or companion drug dexamethasone (DXM) on the locomotor activity and cartilage structure of elderly Wistar rats (n = 40). Long-term TMZ treatment selectively inhibited the horizontal, but not vertical locomotor activity of the rats (6.7-fold, p < 0.01) and resulted in delamination of the superficial epiphyseal cartilage of the femoral epiphysis of knee joints, a 2-fold decrease in mean thickness of epiphyseal cartilage (p < 0.001), and changes in the proliferative and maturation cartilage zones ratio. The simultaneous use of DXM attenuated TMZ-induced changes in cartilage thickness and integrity and compensated the decrease in horizontal locomotor activity of experimental animals. Nevertheless, combined TMZ/DXM treatment still significantly affected the structure of proximal tibial, but not distal femoral epiphysis of knee joints of the rats. These changes were accompanied by the increased content of total glycosaminoglycans (GAGs) and their partial re-localisation from chondrocytes into tissue matrix, as well as the decrease in sulfated GAGs content in both compartments. Taken together, the results demonstrate that long-term treatment with TMZ results in a significant decrease in locomotor activity of elderly Wistar rats and the reorganisation of their knee joint cartilage structure, while DXM treatment attenuates those effects. So, use of DXM or chondroprotective drugs might be beneficial to maintain quality of life for TMZ-treated cancer patients.

Abstract
While glucocorticoids have been used for over 50 years to treat rheumatoid and osteoarthritis pain, the prescription of glucocorticoids remains controversial because of potentially harmful side effects at the molecular, cellular and tissue levels. One member of the glucocorticoid family, dexamethasone (DEX) has recently been demonstrated to rescue cartilage matrix loss and chondrocyte viability in animal studies and cartilage explant models of tissue injury and post-traumatic osteoarthritis, suggesting the possibility of DEX as a disease-modifying drug if used appropriately. However, the literature on the effects of DEX on cartilage reveals conflicting results on the drug's safety, depending on the dose and duration of DEX exposure as well as the model system used. Overall, DEX has been shown to protect against arthritis-related changes in cartilage structure and function, including matrix loss, inflammation and cartilage viability. These beneficial effects are not always observed in model systems using initially healthy cartilage or isolated chondrocytes, where many studies have reported significant increases in chondrocyte apoptosis. It is crucially important to understand under what conditions DEX may be beneficial or harmful to cartilage and other joint tissues and to determine potential for safe use of this glucocorticoid in the clinic as a disease-modifying drug.
