Pharmacological treatment of ectopic pregnancy: Accuracy, safety and cost-effectiveness of day 1-7 ß-hCG measurements.

OBJECTIVE: The aim of the present study was to compare accuracy, safety and cost-effectiveness of three ß-hCG measurements protocols, applied in managing ectopic pregnancies (EP) with methotrexate (MTX): (1) day 1 to 7 ß-hCG levels, (2) day 1 to 4 ß-hCG levels and (3) day 4 to 7 ß-hCG levels. METHODS: Cost-minimization analysis (CMA) based on a retrospective study of patients treated with single-dose MTX for EP, was evaluated at a single institution between January 2001 to May 2021. Successful MTX treatment was defined as no surgical intervention. We evaluated safety by analyzing cases of day 4 interventions and cases of inconsistency between the different protocols. Predicting accuracy was assessed by the area under the receiver operating characteristic (AUC) curve. RESULTS: A total of 229 patients with single dose MTX treatment were included. Overall, 184 (80.3%) patients were treated successfully with a single dose of MTX. For days 1 and 7 the optimal cutoff point was 7% reduction in ß-hCG levels with sensitivity, specificity and PPV of 76.6% (69.9-82.5, 95% CI), 75.5% (60.5-87.1, 95% CI) and 92.8% (88.4-95.6, 95% CI), respectively. There was no significant difference between the protocols' AUC. None of the patients had any change of management during their day 4 visit in our 20 years of records. The cost for each visit day (day 4 and 7) was calculated with a total cost of 251 USD per patient. CONCLUSION: Patients treated with MTX for EP, measurement of day 1 and day 7 ß-hCG serum levels has a cost minimization advantage and is not inferior to the traditional protocol for predictive accuracy and safety.

The efficiency of cabergoline vs pyridoxine for lactation inhibition-a randomized controlled trial.

BACKGROUND: Some mothers may seek lactation inhibition on personal, social, or medical grounds. The common drug used for lactation inhibition is cabergoline. Several adverse effects and contraindications are known for this drug. Its use is contraindicated for patients with hypertensive disorders and fibrotic, cardiac, or hepatic diseases. In addition, pyridoxine (vitamin B6) has been used for this indication, with no significant adverse effect, following studies that demonstrated its efficacy. OBJECTIVE: This study aimed to compare the efficiency of cabergoline vs pyridoxine for lactation inhibition. STUDY DESIGN: A randomized controlled trial was conducted. Postpartum patients who requested lactation inhibition were randomly allocated to receive either cabergoline (1 mg once on postpartum day 1 or divided to 0.25 mg twice a day for 2 days thereafter, according to the departmental protocol, which is in line with the manufacturer recommendations) or pyridoxine (200 mg 3 times a day for 7 days). The patients enrolled were free of diseases in which contraindications to cabergoline are present. All patients completed a questionnaire for assessing breast engorgement, breast pain, and milk leakage on a scale of 0 (no symptom) to 5 (severe symptom) on days 0, 2, 7, and 14. The primary outcome was lactation inhibition success, defined as a score of 0 for both engorgement and pain on day 7. The secondary outcomes included the assessment of milk leakage, adverse effects, fever, mastitis, and treatment discontinuation or alteration. RESULTS: Of note, 45 and 43 patients received cabergoline or pyridoxine, respectively, and were included in the analysis following the intention-to-treat principle. Cabergoline was superior to pyridoxine in inhibiting lactation at day 7 (78% vs 35%, respectively; P<.0001). Mild symptoms, defined as a score of 0 to 2 for breast engorgement and pain, at day 7 were 40 (89%) in the cabergoline group and 29 (67%) in the pyridoxine group (P=.01). The incidence of milk leakage was lower in the cabergoline group after 7 and 14 days than in the pyridoxine group (9% vs 42% [P=.0003] and 11% vs 31% [P=.02], respectively). Cabergoline had more adverse effects than pyridoxine (31% vs 9%, respectively; P=.01), but all adverse effects were mild. The rates of mastitis and fever that were related to engorgement were similar in the cabergoline and pyridoxine groups (4 [9%] vs 2 [5%], respectively; P=.67). Furthermore, 9 patients (21%) in the pyridoxine group switched to or added cabergoline because of treatment failure. Accordingly, on day 7, the pyridoxine success rate was reduced from 35% (15 women) to 28% (12 women) and from 67% (29 women) to 53% (23 women) for a score of 0 and 0 to 2 for both engorgement and pain, respectively. CONCLUSION: Cabergoline was superior to pyridoxine in inhibiting lactation. Cabergoline had more adverse effects, but no major adverse effect was documented in either treatment group. As pyridoxine inhibited lactation successfully in previous studies and in 67% of patients in this study, its use should be considered in women with contraindications for cabergoline.

Postpartum hemorrhage among twin pregnancies - Medically assisted versus spontaneously conceived.

INTRODUCTION: In singleton pregnancies, an increased risk of Postpartum hemorrhage (PPH) have been linked with assisted reproductive technology (ART) and abnormal placentation. It is unknown wheather such association exists in twin pregnancies conceived by Medically assisted reproduction (MAR). The aim of the current study was to compare maternal blood loss among twin pregnancies conceived by different types of MAR treatments to spontaneously conceived twins and to identify the cycle characteristics if an association exits. METHODS: Retrospective study conducted on data collected between 2011 and 2020. The study cohort included all twin pregnancies conceived by MAR and born at our institution. Controls were spontaneously conceived twins matched for maternal age on a 1:2 (study: controls) ratio. RESULTS: Overall 113 MAR twin births categorized into three groups; 25 ovulation induction, 59 fresh ART, 29 frozen-thawed ART cycles, and 226 controls were included. The incidence of PPH was higher among MAR twin pregnancies (5.3%) compared to the controls (4%). The highest incidence was observed among women in the frozen-thawed group (13.8%) which differed significantly compared with the controls (p = 0.024). A significant difference was also observed in the mean decrease of postpartum hemoglobin levels between these two groups (2.13 g/dL versus 1.3 g/dL respectively, p = 0.002). Blood transfusion was nearly 2.5 times more common in the frozen-thawed group (3.4%) compared to the control group (1.3%). DISCUSSION: The present study demonstrates that frozen embryo transfer (FET) ART-conceived twin pregnancies are associated with a markedly increased rate of PPH compared to spontaneously conceived twins.
