[The value of serum galactomannan detection for diagnosis of invasive aspergillosis in hematopoietic stem cell transplant recipients].

OBJECTIVE

To evaluate the value of serum galactomannan (GM) detection for diagnosis of invasive aspergillosis (IA) in hematopoietic stem cell transplant recipients.

METHODS

The serum GM concentration in 167 sera from 46 patients was detected by Platelia Aspergillus double-sandwich enzyme linked immunosorbent assay (PADSELISA). According to the diagnostic criteria of invasive fungal infections in China, the diagnostic changes were evaluated, the sensitivity, specificity and predictive values were calculated.

RESULTS

The sensitivity and specificity of the PADSELISA were 81.8% and 93.3% and the positive and negative predictive values were 90.0% and 87.5% respectively. There were 15 positive cases, and 31 negative cases, and the probable IA cases were increased from 11 to 19 after the GM detection. Moreover, the serous level of galactomannan was correlated with the prognosis of the IA.

CONCLUSIONS

The PADSELISA for GM detection is a reliable method for early diagnosis and treatment of IA in hematopoietic stem cell transplant recipients.
