Summary

Maternal serum levels of beta-human chorionic gonadotropin (beta-hCG), estradiol (E2), and progesterone (P) are significantly lower in ectopic pregnancies (EPs) compared to normal intra-uterine pregnancies (IUPs). While E2 and P levels show overlap, they may aid in earlier EP diagnosis.

Area of Science:

  • Reproductive Endocrinology
  • Maternal-Fetal Medicine
  • Biochemistry

Background:

  • First-trimester pregnancy complications, including ectopic pregnancy (EP), pose significant risks.
  • Accurate early diagnosis of EP is crucial for effective management and improved maternal outcomes.
  • Maternal serum biomarkers are frequently used to assess pregnancy viability and detect abnormalities.

Purpose of the Study:

  • To investigate and compare maternal serum levels of key hormones and tumor markers in normal intra-uterine pregnancies (IUPs), spontaneous abortions, and ectopic pregnancies (EPs).
  • To evaluate the diagnostic potential of serum estradiol (E2) and progesterone (P) in differentiating between IUPs and EPs.

Main Methods:

  • Prospective study involving serum sample collection from women in the first trimester of pregnancy.

  • Measurement of beta-human chorionic gonadotropin (beta-hCG), progesterone (P), estradiol (E2), human placental lactogen (HPL), alpha-fetoprotein (AFP), and cancer antigen 125 (CA 125).
  • Statistical analysis to compare biomarker levels between groups: normal IUPs (n=20), spontaneous abortions (n=15), and confirmed EPs (n=31).

    • Main Results:

    • Significantly lower mean serum levels of beta-hCG, E2, and P were observed in patients with EPs compared to normal IUPs (p < 0.001) and spontaneous abortions (p < 0.05).
    • No significant differences in serum HPL, AFP, and CA 125 levels were found among the study groups.
    • A considerable overlap in serum P and E2 levels between IUPs and EPs precluded the identification of a definitive discriminatory cutoff value.

    Conclusions:

    • Serum beta-hCG, E2, and P levels are significantly reduced in ectopic pregnancies.
    • While individual E2 and P levels lack a clear discriminatory threshold to distinguish EPs from IUPs, their inclusion in diagnostic workups may support earlier EP detection.
    • HPL, AFP, and CA 125 are not reliable biomarkers for differentiating these first-trimester pregnancy outcomes.
