ABSTRACT
【Objective】 To explore the correlation between the severity of jaundice in ABO hemolytic disease of fetus and newborn (HDFN) and multiple indicators, in order to achieve accurate diagnosis, timely treatment, and prevent complications in ABO HDFN. 【Methods】 From March 2020 to February 2023, a total of 283 ABO HDFN in our hospital were classified into mild, moderate and severe groups based on total bilirubin levels. The differences in basic data, relevant laboratory indicators and the agglutination intensity of the three hemolysis tests were analyzed and compared. 【Results】 In the severe group, 75% (12/16) were male infants, which was significantly higher compared to 37.5% (57/152) in the moderate group (P<0.05). The values (mg/dL) of transcutaneous jaundice in the mild, moderate and severe groups were:forehead 9.88±1.93 vs 12.34±2.01 vs 15.56±2.69, face 10.25±2.27 vs 13.28±2.32 vs 15.99±2.86, chest 9.67±2.16 vs 12.51±2.11 vs 15.33±2.36, respectively. The values(µmol/L) of direct bilirubin (DBIL) and indirect bilirubin (IBIL) were 9.87±2.06 vs 11.90±2.59 vs 16.12±4.73, and 159.36±37.55 vs 252.98±30.52 vs 353.76±55.68, respectively, and the differences between the mild, moderate and severe groups were statistically significant (all P<0.05) . The creatine kinase (CK) values(unit/L) of mild, moderate and severe groups were 664.15±498.26 vs 500.51 ±451.63 vs 402.63±224.27, and the difference between the mild group and the other two groups was statistically significant (P<0.05) . There was no statistically significant difference in the agglutination intensity of the three hemolysis tests among HDFN with different severity of jaundice. 【Conclusion】 Clinicians can predict the severity of jaundice in light of gender, transcutaneous jaundice, DBIL, IBIL and CK of ABO HDFN, for further and graded treatment, so as to avoid the sequelae or even life-threatening consequences caused by ABO HDFN.
