ABSTRACT

Objective To investigate the treatment evaluating value of ESAT－6 and CFP－10 in T－SPOT.TB kit for tuberculous vertebral osteomyelitis.Medthods This retrospective study analyzed 29 cases diagnosed as TVO in the First Affiliated Hospital of Kunming Medical University from January 2013 to January 2016. All cases were the first－time consultancy. The Wilcoxon－singed－rank－test and chi－square test were used to analyze the changes of ESAT－6 and CFP－10 in the procedure of treatment. The linear－regression analysis was used to analyze the relationship between ESR, CRP, VAS and two specific antigens.Results The pretherapeutic spot counts of ESAT－6 and CFP－10 were compared with the first and the last follow－up respectively. The results of two antigenic spots change showed a higher consistency (P＜0.05) .The positive rates of CFP－10 at the prior treatment, the first follow－up and the last follow－up were 86.20% , 79.31% and 58.62% respectively. The result of chi－square test showed a higher consistency (P＜0.05) . ESAT－6 only correlated with VAS. CFP－10 had the relationship with VAS and ESR. But all of these relativities were weak.Conclusion The decrease in the spot counts of ESAT－6 and CFP－10 suggest that the treatment is effective,and CFP－10 may be one available index to evaluate the treatment effect.
