AI Article Synopsis
- The study aimed to evaluate the impact of adding PAMG-1 testing to standard ultrasound exams on the use of antenatal corticosteroids (ACS) in women with shortened cervical length.
- It found that fewer women in the PAMG-1 group received ACS compared to the historical control group, but delivery outcomes like timing and NICU admissions showed mixed results.
- The findings suggest that incorporating PAMG-1 testing might help reduce unnecessary ACS treatment in these patients.
Article Abstract
Objectives: To assess the frequency of antenatal corticosteroid (ACS) administration in cases with shortened cervical length by addition of placental alpha-microglobulin-1 (PAMG-1) testing to sonographic examination.
Methods: Single centre retrospective cohort study. Rate of ACS administration was compared between cases with cervical length between 15 and 25 mm and cases with positive PAMG-1 testing and cervical length between 15 and 25 mm. We evaluated the following outcome parameters: Rate of ACS administration, gestational age at delivery, time to delivery, delivery within seven days, delivery <34 and <37 weeks' gestation, rate of admission to neonatal intensive care unit (NICU).
Results: In total, 130 cases were included. "PAMG-1 group" consisted of 68 women, 62 cases built the "historical control group". ACS administration was performed less frequently in the "PAMG-1 cohort" (18 (26%) vs. 46 (74%); p<0.001). The rate of delivery within seven days did not differ (2 (3%) vs. 4 (6.5%); p=0.4239). The rates of delivery <34 weeks' gestation (7 (10%) vs. 9 (15%); p=0.4643) and <37 weeks' gestation (19 (28%) vs. 26 (42%); p=0.0939) did not differ. Time to delivery interval was longer in the PAMG-1 group (61.5 vs. 43 days, p=0.0117). NICU admission occurred more often in the "historical control group" (22 (38%) vs. 28 (60%); p=0.0272).
Conclusions: Addition of biomarker testing can help to avoid unnecessary ACS administrations in women with shortened cervical length.

Trends in antenatal corticosteroid administration: did our timing improve?

Objectives: We aimed to analyze trends in the rate of effective antenatal corticosteroid prophylaxis (ACS) administrations across a spectrum of typical diagnoses associated with preterm birth.
Methods: In this retrospective study we utilized delivery data after ACS from 2014 to 2020 at Charité Berlin, Germany. We evaluated the rate of effective ACS administrations defined as ≤10 days between last dose of ACS and delivery as well as the rate of post-ACS births on/after 37 + 0 weeks.

Objectives: Placental alpha microglobulin-1 (PAMG-1) is a novel biomarker detected in cervicovaginal discharge in patients threatened with preterm birth (PTB). This study aimed to show a single centre experience of assessment of imminent spontaneous PTB risk in patients with symptoms suggesting preterm labour (PTL).
Material And Methods: The study group consisted of 46 women with singleton pregnancies between 24 + 0/7 and 33 + 6/7 weeks of gestation who presented with symptoms of threatened PTL, with cervical dilatation of < 3 cm, cervical length (CL) of < 30 mm and clinically intact fetal membranes.
