Study of related inflammatory factor influence in rheumatoid arthritis patients with umbilical cord mesenchymal stem cells / 中国免疫学杂志

ABSTRACT

To study the umbilical cord mesenchymal stem cells impact of inflammatory factors in rheumatoid arthritis patients.Methods:94 cases of patients with RA hospitalized in our department from April 2011 to December 2012 were treated with umbilical cord mesenchymal stem cells (MSCs) UC,during which the cell therapy scholastic ethics was committed approvally and patients′informed consents were separately signed .94 patients were directly intravenous infusion with 40 ml UC-MSCs ( 4×107 cells/ml),including 57 cases with two UC-MSCs therapy.We used multifunctional flow lattice Luminex 200 analysis to detect contents of 13 kinds of factors in serum such as TNF alpha,IFN-gamma,IL-1β,IL-4,IL-6,IL-8,IL-10,ie,and detected CPR,ESR,assessment DAS28,HAQ,and ARA.Follow-up treatments were performed after 1 week,3 months,6 months ( two cells treatment of 60 cases).Results:①DAS28,HAQ grading standards,were decreased (P<0.01) in 3 months and 6 months before the patients treatment ,2 times than one continue treatment decreased ( P<0.01 );the ESR and CRP in 1 week dropped significantly after treatment ( P<0.01),3 months,6 months before the treatment also decreased (P<0.05).②IL-6,TNF alpha were in falling levels after 1 week,3 months and 6 months treatment ,( P<0.05 ).Conclusion: We proved the inflammatory factors directly related with clinical indicators and symptoms of RA patients .94 cases of patients with other inflammatory factor (IL-17,IL-4,IL-10,etc.) also had some change,we still needed further observation.According to drug rheumatism guide at the same time , collaborative using with UC-MSCs could make RA patients improve local and systemic inflammatory response ,prevent disease progression.
