Abstract:
OBJECTIVE:To investigate the auxiliary diagnostic value of serum adenosine deaminase (ADA) in acute leukemia (AL) at clinical test.
METHODS:123 AL patients hospitalized in Zhejiang hospital from November 2018 to March 2020 were enrolled as the observation group, and 98 healthy people in the same period were randomly enrolled as the control group. AL patients were divided into two groups: 77 acute myeloid leukemia (AML) patients for AML group and 46 acute lymphoblastic leukemia (ALL) patients for ALL group. The levels of adenosine deaminase (ADA), alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH) and homocysteine (Hcy) in serum of the patients were detected, and the correlation of ADA with these items was analyzed. Receiver operating characteristic curve (ROC) was used to analyze the clinical diagnostic value of ADA, Yoden index was used to confirm the best cut-off point.
RESULTS:The serum ADA level in AL patients was significant higher than that in control group (P < 0.05). The results of Pearson correlation analysis showed that there was a significant positive correlation of ADA with Hcy, ALT, AST, GGT, LDH in AML group (r = 0.47, r = 0.28, r = 0.37, r = 0.22, r = 0.55); and also there was a significant positive correlation of ADA with GGT in ALL group (r = 0.54). In AML group, the maximum area under ROC curve was 0.761 (P = 0.00), 95% confidence interval was 0.682-0.841, sensitivity was 54.50%, specificity was 98.90%, and the best cut-off point was 17.1 U/L. In ALL group, the maximum area under ROC curve was 0.785, 95% confidence interval was 0.694-0.877, sensitivity was 65.90%, specificity was 84.00%, and the best cut-off point was 13.45 U/L.
CONCLUSION:The detection of ADA in serum can be used as an auxiliary examination in patients with AL, which can provide a certain value for the diagnosis of the disease.
