Biomarkers for early diagnosis of aseptic loosening after total hip replacement

چکیده
Numbers of patients are suffering from aseptic loosening after total hip replacement, which can need further revision surgery. Particle-induced osteolysis has been considered as a major cause of aseptic loosening after hip joint replacement. This is a prospective study, and there are 82 patients of unilateral osseous arthritis and 10 normal physical examination people in our hospital for this study. The participants were divided into four groups, including control group, No arthroplasty group, joint replacement group and loosened THA group. The osteoclasts cell morphology and osteoclast activity were observed by using the microscopy. The mRNA levels of MCP-1, TNF and RANKL were detected by using the Quantitative reverse transcriptase-polymerase chain reaction (RT-PCR). The results indicated that the bone erosion rates of the joint replacement respectively reached 12.9% and 31.6% after cultured 14 d and 21 d, compare with control, which was remarkably increased (P<0.05). The bone erosion rates of loosened THA also reached 43.4% and 88.4%, respectively, after cultured 14 d and 21 d, compare with control, which remarkably increased (P<0.01). The loosened THA group of expression level of MCP-1 gene were much higher than joint replacement. Expression level of RANKL gene of loosened THA group was higher 7.4 times than joint replacement. In conclusion, the osteoclast morphology and activity in the peripheral blood and expression levels of MCP-1 can be used for early diagnosis of aseptic loosening after total hip replacement.

OBJECTIVE Genetic factor plays an important role in early failure of total hip arthroplasty (aseptic loosening) etiology, and TIMP-1 gene may be involved. The present study was conducted to reveal possible association between TIMP-1 polymorphisms with the risk of early failure of total hip arthroplasty (THA) (aseptic loosening). METHODS The TIMP-1 single nucleotide polymorphisms (SNPs) rs4898...

BACKGROUND Aseptic loosening is a main cause for revision surgery after total hip arthroplasty (THA) and there is no reliable marker for the early detection of patients at high risk. This study has been performed to validate association of the T393C polymorphism (rs7121) in the GNAS1 gene, encoding for the alpha-subunit of heterotrimeric G-protein Gs, with risk for and time to aseptic loosening...

BACKGROUND Inflammatory responses to wear debris cause osteolysis that leads to aseptic prosthesis loosening and hip arthroplasty failure. Although osteolysis is usually associated with aseptic loosening, it is rarely seen around stable implants. Aseptic implant loosening is a simple radiologic phenomenon, but a complex immunological process. Particulate debris produced by implants most commonl...
