Diagnostic Value of Serum Adenosine Deaminase in Myelodysplastic Syndromes: an Observational Study
Background:
This study aimed to explore the diagnostic value of serum adenosine deaminase (ADA) in patients with myelodysplastic syndromes (MDS) and identify potential risk factors for MDS.
Methods:
Eighty patients with MDS and 80 healthy individuals were included. The serum ADA level was found to be significantly higher in patients with MDS compared with that of healthy controls (p = 0.014).
Results:
The receiver operator characteristic curve (ROC) for ADA had an area under curve (AUC) of 0.807 (p = 0.0018). Serum ADA level of 4.5 U/L had a sensitivity of 71.43% and specificity of 80% for MDS diagnosis. The multivariate analysis showed hemoglobin (Hb, OR = 1.322, 95% CI: 1.035 - 2.323, p = 0.039), prothrombin time (PT, OR = 1.524, 95% CI: 1.156 - 3.280, p = 0.042), fibrinogen (OR = 1.335, 95% CI: 1.022 - 2.775, p = 0.027), calculated international normalized ration (INR, OR = 2.212, 95% CI: 1.320 - 3.085, p = 0.038), D-dimer (OR = 2.043, 95% CI: 1.623 - 4.293, p = 0.038), fibrin degradation product (FDP, OR = 2.525, 95% CI: 1.129 - 3.340, p = 0.029), and serum ADA (OR = 2.057, 95% CI: 1.248 - 3.572, p = 0.033) were independently associated with MDS.
Conclusions:
Serum ADA might be a potential biomarker in the diagnosis of MDS. Serum ADA level, Hb level, PT, fibrinogen level, INR, D-dimer, and FDPs were independent risk factors of MDS.
