Abstract:
OBJECTIVE:To explore the clinical related factors of leucopenia induced by azathioprine in the treatment of inflam-matory bowel disease (IBD). METHODS:Clinical information of 114 IBD patients were collected from our hospital during Jan. 2013-Mar. 2015. Steady concentration of AZA metabolite 6-thioguanine(6-TGNs)in red blood cell was determined by HPLC. The correlation of patient’s gender,age,diseases,AZA daily dose and blood concentration of 6-TGNs with leucopenia induced by AZA were investigated. The optimal critical value of leucopenia could be predicted with ROC curves. RESULTS:Among 114 IBD patients,40 patients suffered from leucopenia(35.1%). There was no statistical significance in the proportion of leucopenia among patients with different age,gender,diseases and AZA daily dose(P>0.05). There was statistical significance in the proportion of leucopenia among patients with different concentrations of 6-TGNs(P<0.05). Mean blood concentration of 6-TGNs in leukopenia patients [(407.82±262.88)pmol/(8×108)RBC] was higher than patients with normal leukocyte level [(275.85±118.37)pmol/(8× 108)RBC],with statistical significance(P<0.05). ROC curve predicted that the optimal critical value of leucopenia was blood con-centration of 6-TGNs>291.04 pmol/(8 × 108)RBC. CONCLUSIONS:AZA induced leucopenia may be related to the concentration of 6-TGNs in red blood cell of IBD patients,and high concentration of 6-TGNs is risk factors of leucopenia. Clinicians can provide AZA individual treatment for IBD patient to reduce the occurrence of leucopenia according to routine blood test and the concentra-tion of 6-TGNs.
