| 8 | Performance of alpha-defensin lateral flow test after synovial fluid centrifugation for diagnosis of periprosthetic knee infection显示文摘BACKGROUND The quantitative alpha-defensin enzyme-linked immunosorbent assay(ELISA)demands a prior synovial fluid centrifugation,whereas this processing is not routinely required prior to the alpha-defensin lateral flow test.AIM To evaluate whether a prior synovial fluid centrifugation could lead the lateral flow performance to achieve comparable results to ELISA during periprosthetic joint infection(PJI)diagnosis.METHODS Fifty-three cases were included in this study:22 classified as PJI and 31 classified as aseptic cases,according to Musculoskeletal Infection Society 2013 criteria.Synovial fluid samples were submitted to centrifugation,and the supernatant was evaluated by ELISA and lateral flow tests.The sensitivity(SE),specificity(SP)and accuracy of each method were calculated as well as the agreement between those two methods.RESULTS In all of the 31 samples from aseptic patients,alpha-defensin ELISA and lateral flow tests showed negative results for infection.Regarding the 22 infected patients,the lateral flow test was positive in 19 cases(86.4%)and the ELISA was positive in 21(95.5%).Sensibility,SP and accuracy were,respectively,86.4%(95%CI:65.1%-97.1%),100%(95%CI:88.8%-100%)and 93.2%(95%CI:82.8%-98.3%)for the lateral flow test and 95.5%(95%CI:77.2%-99.9%),100%(95%CI:88.8%-100%)and 98.1%(95%CI:89.9%-100%)for ELISA.An agreement of 96.2%between those methods were observed.No statistical difference was found between them(P=0.48).CONCLUSION Alpha-defensin lateral flow test showed high SE,SP and accuracy after a prior synovial fluid centrifugation,achieving comparable results to ELISA.Considering the lower complexity of the lateral flow and its equivalent performance obtained in this condition,a prior centrifugation might be added as a valuable step to enhance the PJI diagnosis. | Rodrigo Calil Teles Abdo Riccardo Gomes Gobbi Chilan Bou Ghosson Leite Sandra Gofinet Pasoto Elaine Pires Leon Ana Lucia Lei Munhoz Lima Eloisa Bonfa José Ricardo Pécora Marco Kawamura Demange | 2021 | World Journal of Orthopedics2021，12，8： | 0 |
| 9 | Quantitative alpha-defensin testing: Is synovial fluid dilution important?显示文摘BACKGROUND Alpha-defensin has been widely studied for the diagnosis of periprosthetic joint infection(PJI).However,there is a lack of detailed information regarding the proper laboratory technique of the enzyme-linked immunosorbent assay(ELISA)method,such as sample dilution.AIM To assess the influence of dilution in the synovial fluid during ELISA for the diagnosis of knee PJI;and determine which dilution presents a better performance.METHODS Forty samples of synovial fluid from arthroplasty knees were included,17 in the infected group and 23 in the aseptic group,according to Musculoskeletal Infection Society criteria.Initially,five synovial fluid samples from each group were assessed for quantitative analysis of alpha-defensin using ELISA.Different dilution ratios(1:10,1:100,1:500,1:1000 and 1:5000)were tested based on the predetermined cutoff value of 5.2 mg/L.The dilutions that performed better were used to compare the results of all samples.RESULTS For infected cases,a gradual increase in the dilution of synovial fluid samples led to an equivalent increase in alpha-defensin level.The same was not observed in the aseptic cases.Both 1:1000 and 1:5000 dilutions presented satisfactory results to differentiate infected and aseptic cases.Further analyses were performed using 1:1000 and 1:5000 for all 40 samples.The 1:1000 dilution resulted in a sensitivity of 88.2%(95%CI,66%-98%)and specificity of 95.7%(95%CI,79%-99%),whereas the 1:5000 dilution presented a sensitivity of 94.1%(95%CI,73%-99%)and a specificity of 100%(95%CI,86%-100%).CONCLUSION The synovial fluid dilution had an important influence on the alpha-defensin ELISA results.Dilutions of 1:5000 showed the best performance for the diagnosis of knee PJI.The results of this study set the basis for a more reliable and reproducible alpha-defensin ELISA during the investigation of PJI,contributing to the expansion of this technique in different treatment centers worldwide. | Rodrigo Calil Teles Abdo Riccardo Gomes Gobbi Chilan Bou Ghosson Leite Sandra Gofinet Pasoto Elaine Pires Leon Ana Lucia Lei Munhoz Lima Eloisa Bonfa JoséRicardo Pécora Marco Kawamura Demange | 2022 | World Journal of Orthopedics2022，13，8： | 0 |
