Residual liver stiffness in the postpartum period in women with preeclampsia and healthy women: A case-control study.

OBJECTIVE: We aimed to assess the presence of residual liver stiffness in preeclampsia 45 days after delivery. STUDY DESIGN: This was a longitudinal case-control study to assess the association between residual liver stiffness, measured 45 days postpartum, and hypertensive disorders of pregnancy. Cases were obstetric patients admitted with hypertension during pregnancy (preeclampsia with and without severe features, or HELLP syndrome) between June 2019 and September 2021. Controls were obstetric patients with similar ages, social status, gestational age (assessed by the first-trimester ultrasound), and geographical areas between the same period. A 2:1 case-control match was considered. MAIN OUTCOME MEASURES: We recorded blood pressure and laboratory tests during the hospital stay. We measured the residual liver stiffness in preeclampsia participants and controls 45 days after delivery. RESULTS: We recruited 99 hypertensive patients and 46 control patients. The residual liver stiffness was higher in hypertensive cases than controls (4.6 [3.9-5.3] kPa vs. 4.0 [3.2-5.2] kPa; p = 0.039). Linear regression results showed that systolic and diastolic blood pressures and alanine aminotransferase positively correlated with liver stiffness values (p < 0.01). CONCLUSIONS: Preeclampsia and disease severity were associated with residual liver stiffness. Prospective studies should further evaluate the clinical implications of these findings.

New obstetric systemic inflammatory response syndrome criteria for early identification of high-risk of sepsis in obstetric patients.

OBJECTIVES: We aimed to establish new cut-off values for SIRS (Systemic Inflammatory Response Syndrome) variables in the obstetric population. METHODS: A prospective cohort study in pregnant and postpartum women admitted with systemic infections between December 2017 and January 2019. Patients were divided into three cohorts: Group A, patients with infection but without severe maternal outcomes (SMO); Group B, patients with infection and SMO or admission to the intensive care unit (ICU); and Group C, a control group. Outcome measures were ICU admission and SMO. The relationship between SIRS criteria and SMO was expressed as the area under the receiver operating characteristics curve (AUROC), selecting the best cut-off for each SIRS criterion. RESULTS: A total of 541 obstetric patients were enrolled, including 341 with infections and 200 enrolled as the reference group (Group C). The patients with infections included 313 (91.7%) in Group A and 28 (8.2%) in Group B. There were significant differences for all SIRS variables in Group B, compared with Groups A and C, but there were no significant differences between Groups A and C. The best cut-off values were the following: temperature 38.2 °C, OR 4.1 (1.8-9.0); heart rate 120 bpm, OR 2.9 (1.2-7.4); respiratory rate 22 bpm, OR 4.1 (1.6-10.1); and leukocyte count 16,100 per mcl, OR 3.5 (1.6-7.6). CONCLUSIONS: The cut-off values for SIRS variables did not differ between healthy and infected obstetric patients. However, a higher cut-off may help predict the population with a higher risk of severe maternal outcomes.
