Abstract

Study Objective: To investigate the trends in liver function tests (LFTs), renal function tests (RFTs), and complete blood count (CBC) between day 1 and day 7 after single- or double-dose methotrexate (MTX) treatment for sonographically confirmed ectopic pregnancies. Design: Single center, retrospective chart review (Canadian Task Force classification II-3). Setting: University-affiliated center. Patients: All patients with a sonographically confirmed ectopic pregnancy after fresh in vitro fertilization-embryo transfer cycles between January 2004 and June 2013 treated with MTX were included. Interventions: Single- or double-dose MTX treatment. Measurements and Main Results: LFTs, specifically alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, and total bilirubin levels, were measured on day of MTX administration (baseline) and 7 days later (day 7). Similar measurements of RFTs (blood urea nitrogen [BUN] and creatinine) and CBC (white blood cell [WBC] and platelets) were also performed. The change in LFTs, RFTs, and CBC (δ) between baseline and day 7 was calculated for both single- and double-dose MTX protocols. Furthermore, the change in LFTs, RFTs, and CBC (δ baseline vs day 7) for single- and double-dose MTX protocols were compared. Complete data was available for 107 patients: 89 (83.2%) and 18 (16.8%) patients received single- and double-dose MTX treatment, respectively. For either single- or double-dose treatment, no significant difference was found between baseline and day 7 ALT, AST, albumin, total bilirubin, BUN, creatinine, WBC, or platelet levels after MTX treatment. A comparison of post-treatment changes in LFTs, RFTs, and CBC (δ baseline vs day 7) also showed no difference between single- and double-dose protocols. Conclusion: Our study suggests that repeating LFTs, RFTs, or CBC on day 7 after single- or double-dose MTX treatment for sonographically confirmed ectopic pregnancies may not be necessary in patients with normal baseline testing on day 1.
