Abstract Background: Although first-trimester subchorionic hematoma (SCH) always concerns expectant parents, its clinical significance remains controversial. This study aimed to examine the relationship between first-trimester SCH and its association with subsequent miscarriage and other perinatal outcomes.Methods: We conducted a retrospective cohort study including 43,660 women who underwent routine prenatal care since the first trimester and then were followed up for maternal and neonatal outcomes. SCH was detected in the first-trimester ultrasound examinations. Robust Poisson regression was used to estimate adjusted risk associations between SCH maternal and neonatal outcomes.Results: A total of 815 (1.87%) SCH were detected in the first-trimester ultrasound examination. The rate of miscarriage was statistically significantly higher in women with SCH than in those without [35.2% vs. 23.9%, P<0.01; adjusted relative risk (RR):1.44, 95% confidence interval (CI): 1.31-1.58]. Subgroup analysis of women with SCH showed a clear trend that the earlier SCH occurred, the higher the risk of miscarriage was [adjusted RR and 95% CI for onset at the gestational weeks of 8-9, 6- 7, and <6 vs. ≥10: 1.30 (0.69-2.46), 2.33 (1.28-4.23), and 4.18 (2.30-7.58), respectively; Ptrend<0.01]. In addition, women with SCH volume ≥1ml showed higher risk than those <1 ml [adjusted RR and 95% CI for 1-4.9 ml, and ≥5 ml vs. <1 ml: 1.36 (1.10-1.68) and 1.56 (1.18-2.07), respectively]. There was no statistically significant difference in the rates of other pregnancy outcomes between women with and without SCH.Conclusions: First-trimester SCH might significantly increase the risk of miscarriage, particularly the one that occurs early and the one with large size. Data from this study do not suggest adverse effects of SCH on other maternal and neonatal outcomes.

Abstract Background: Acute fatty liver of pregnancy (AFLP) and hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome are two uncommon disorders that mimic each other clinically, but are distinct pathophysiologically. This study aimed to compare maternal and neonatal outcomes between AFLP and HELLP syndrome.Methods: This retrospective cohort study was performed at a tertiary referral center in Taiwan between June 2004 and April 2020. We used the Swansea Criteria to diagnose AFLP, and the Tennessee Classification System to diagnose HELLP syndrome. Maternal characteristics, laboratory data, complications, and neonatal outcomes were analyzed.Results: During the study period, 21 women had AFLP and 80 women had HELLP syndrome. There was a higher rate of preeclampsia (95.0% versus 23.8%) in the HELLP syndrome group compared to the AFLP group. However, the AFLP group had more other maternal complications including jaundice (85.7% versus 13.8%), acute kidney injury (61.9% versus 15.0%), disseminated intravascular coagulopathy (66.7% versus 8.8%), and sepsis (47.6% versus 10.0%) compared to the HELLP syndrome group. Nevertheless, higher rates of small for gestational age neonates (57.1% versus 33.3%), neonatal respiratory distress syndrome (39.2% versus 8.3%) and neonatal sepsis (34.2% versus 12.5%) were noted in the HELLP syndrome group.Conclusions: AFLP is associated with a higher rate of multiple organ dysfunction in mothers, whereas HELLP syndrome is associated with a higher rate of neonatal morbidity.

This study aimed to compare maternal and neonatal outcomes between AFLP and HELLP syndrome. Methods This retrospective cohort study was performed at a tertiary referral center in Taiwan between June 2004 and April 2020. We used the Swansea Criteria to diagnose AFLP, and the Tennessee Classification System to diagnose HELLP syndrome. Maternal characteristics, laboratory data, complications, and neonatal outcomes were compared. We analyzed the categorical variables with Chi-square test or Fisher’s exact test and continuous variables with Student’s t test or Mann-Whitney U test. Subsequent logistic regression analyses adjusting by potential confounding factors with significant difference were analyzed. Results During the study period, 21 women had AFLP and 80 women had HELLP syndrome. There was a higher rate of preeclampsia (95.0 % versus 23.8 %) in the HELLP syndrome group compared to the AFLP group. However, the AFLP group had more other maternal complications including jaundice (85.7 % versus 13.8 %), acute kidney injury (61.9 % versus 15.0 %), disseminated intravascular coagulopathy (66.7 % versus 8.8 %), and sepsis (47.6 % versus 10.0 %) compared to the HELLP syndrome group. Nevertheless, higher rates of small for gestational age neonates (57.1 % versus 33.3 %), neonatal respiratory distress syndrome (39.2 % versus 8.3 %) and neonatal sepsis (34.2 % versus 12.5 %) were noted in the HELLP syndrome group. Conclusions AFLP is associated with a higher rate of multiple organ dysfunction in mothers, whereas HELLP syndrome is associated with a higher rate of neonatal morbidity.
