Abstract:
Objective To analyze factors affecting outcomes of single-dose methotrexate(MTX)treatment in patients with ectopic pregnancy.Methods The data of 416 patients with ectopic pregnancy treated by single-dose MTX injection in Obstetrics and Gynecology Hospital,Fudan University from Jan 2019 to Dec 2022 were retrospectively analyzed.MTX was administered on day 1,and the serum β-human chorionic gonadotrophin(β-hCG)levels were measured on posttreatment day 4 and day 7.If serum β-hCG level decreased less than 15%,it was considered as treatment failure,thus the patient was included in the failure group.If serum β-hCG level decreased more than 15%,it was considered as effective initial treatment and β-hCG levels were measured weekly until back to nonpregnant level,thus the patient was included in the success group.Clinical data and treatment outcomes were collected and outcomes-related risk factors were analyzed.Results There were 70 patients in failure group and 346 patients in success group.The proportion of patients with increased β-humanchorionic gonadotrophin(β-hCG)level before MTX treatment in failure group was significantly higher than that of patients in success group(55.2%vs.35.8%,P=0.007)and the proportion of patients with decreased β-hCG level before MTX treatment in failure group was significantly lower than that of patients in success group(43.1%vs.63.6%,P=0.007).Monocyte counts in failure group was significantly lower than that in success group[(0.43±0.13)×109/L vs.(0.47±0.17)×109/L,t=-2.001,P=0.047)].The differences of basal β-hCG level,change speed of β-hCG level,serum albumin,serum creatinine,white blood cell,neutrocyte,mean platelet volume,neutrocyte-lymphocyte ratio,platelet-lymphocyte ratio and lymphocyte-monocyte ratio between the two groups were not significant.Logistic regression analysis suggested the changing patterns of serum β-hCG level and monocyte counts were associated with treatment outcomes.Decreased β-hCG level(OR=2.313,95%CI:1.222-4.379,P=0.010)and monocyte counts≥0.6×109/L(OR=4.018,95%CI:1.207-13.378,P=0.023)were positively correlated with treatment success.Conclusion Decreased β-hCG level MTX treatment and monocyte counts≥0.6×109/L were two independent risk factors for the successful treatment of ectopic pregnancy.
