| 12 | Content of blood cell components,inflammatory cytokines and growth factors in autologous platelet-rich plasma obtained by various methods显示文摘BACKGROUND The evaluation of the efficacy of platelet-rich plasma(PRP) in clinical practice yields conflicting results and raises numerous controversies. This may be due to different concentrations of biologically active components in PRP obtained with the use of different methods of gravity separation.AIM To compare the content, repeatability and correlations between biologically active components in PRP obtained with four different commercial systems.METHODS From a whole blood sample of each of 12 healthy male volunteers, 4 PRP samples were prepared using 4 different commercial kits [Arthrex Autologous Conditioned Plasma(ACP), Mini GPS Ⅲ, Xerthra, Dr. PRP] in accordance with the instructions provided by the manufacturers. A comparative analysis of blood cell components-13 selected inflammatory cytokines and 7 growth factors-in the obtained PRP samples was performed using the Kruskal-Wallis test by ranks. The repeatability of results in each method was evaluated by the estimation of the coefficient of variation. The Spearman correlation was used to estimate the relationship between blood cell content and cytokines.RESULTS Significantly higher concentrations of platelets(PLT), white blood cells(WBC) and red blood cells(RBC) were found in PRP obtained with the use of Mini GPS Ⅲ than in PRP obtained using other systems. Significant differences in the content of growth factors and cytokines in PRP were found. A positive correlation of the amount of PLT, RBC and WBC with the concentration of most of the growth factors was found but in only three inflammatory cytokines. The obtained correlations between blood cell components and cytokines differed between the systems in terms of statistical significance, which may be due to insufficient sample size. The repeatability of the obtained PLT concentration also varied between protocols with the lowest in Xerthra and the highest in Arthrex ACP.CONCLUSION Significant differences in the content of biologically active components and their repeatability were found in PRP obtained by various methods, providing new data for further research. | Maciej Dejnek Jarosław Witkowski Helena Moreira Sylwia Płaczkowska Piotr Morasiewicz PawełReichert Aleksandra Królikowska | 2022 | World Journal of Orthopedics2022，13，6： | 1 |
