Hormonal and electrolyte predictors for methotrexate versus surgery in ectopic pregnancy

Area of Science:

• Reproductive Endocrinology
• Clinical Biochemistry
• Pharmacology

Background:

• Ectopic pregnancy poses significant risks, with methotrexate (MTX) as a primary non-surgical treatment.
• Predicting MTX treatment success is crucial for optimizing patient management and avoiding surgical intervention.

Purpose of the Study:

• To investigate the association between maternal serum electrolyte and hormone levels and MTX treatment success in ectopic pregnancies.
• To identify biochemical markers that predict MTX efficacy and guide clinical decision-making.

Main Methods:

• Retrospective analysis of 372 patients treated with single-dose MTX for ectopic pregnancy.
• Comparison of maternal serum electrolyte (potassium, magnesium, albumin) and hormone (beta-hCG) levels between MTX-successful and surgical intervention groups.

Main Results:

• Higher serum potassium and albumin levels, and lower magnesium levels were associated with successful MTX treatment.
• Significantly lower beta-hCG levels were observed in the MTX-successful group compared to the surgical group.
• Higher hemoglobin and hematocrit levels were also noted in patients who responded well to MTX.

Conclusions:

• Maternal serum potassium, albumin, and magnesium levels are potential predictive markers for MTX treatment success in ectopic pregnancy.
• Dietary modifications to optimize these electrolyte levels may enhance MTX efficacy.
• Individualized biochemical profiling can improve ectopic pregnancy management and reduce surgical rates.
