RESUMO

Background: Unlike tachyarrhythmias, which are common in pregnancy, there is a paucity of data regarding maternal bradycardias. Our objective was to describe the characteristics, associated conditions, and prognosis of women who develop bradycardia post-partum. Method: We conducted a retrospective chart review of patients referred to the Obstetrical Medicine service at British Columbia Women's Hospital from January 2012 to May 2020 for post-partum maternal bradycardia. Results: Twenty-four patients with post-partum bradycardia were included (age 34.2 ± 4.8 years; heart rate 40.4 ± 8.1 beats per minute; blood pressure 131/72 mm Hg). Sinus bradycardia (79.2%) was the most common rhythm. Dyspnea (29.4%) and chest pain (23.5%) were common symptoms. Mean time to resolution of bradycardia was 3.6 ± 3.8 days. Associated conditions potentially explaining the bradycardia were preeclampsia (54.1%), underlying (16.7%), medications (8.3%), and neuraxial anesthesia (8.3%). Conclusions: Maternal bradycardia is an uncommon condition complicating the post-partum period, that is generally self-limiting, with the majority only require clinical observation.

RESUMO

Background: COVID-19 pandemic has influenced health care delivery. We conducted an observational study to understand how obstetric medicine (ObM) physicians utilized home blood pressure monitoring (HBPM) to manage hypertension in pregnancy. Methods: Pregnant participants with risk factors or diagnosis of hypertensive disorders of pregnancy (HDP) were enrolled, May 2020-December 2021, and provided with validated home blood pressure (BP) monitor. ObM physicians completed questionnaires to elicit how home BP readings were interpreted to manage HDP. Results: We enrolled 103 people: 44 antepartum patients (33.5 ± 5 years, gestational age of 24 ± 5 weeks); 59 postpartum patients (35 ± 6 years, enrolled 6 ± 4 days post-partum). ObM physicians used range of home BP readings (70%) for management of HDP. Conclusions: HBPM to manage HDP is acceptable and can be used to manage hypertension during pregnancy. Further studies are needed to assess the generalizability of our findings and the safety of HBPM reliance alone in management of HDP.

RESUMO

INTRODUCTION: the objective of this study was to evaluate the incidence of Chronic Intervillositis of Unknown Etiology (CIUE) at our institution and to report on the pregnancy outcomes based on severity of lesions. METHODS: retrospective cohort study including 29 889 perinatal specimens from 27 968 patients. The pathology database at our institution was queried for the keywords "intervillositis" and "CIUE" between February 2006 and April 2019. Histology was re-examined using a standardized diagnostic criterion to confirm diagnosis. Cases in which diagnosis was confirmed were categorized as low grade (5-49% intervillous space involvement) or high grade (≥50% involvement). Interventions and pregnancy outcomes were recorded. RESULTS: The overall prevalence of CIUE is 0.17% (47 of 27 968 patients), with significantly higher prevalence in 1st trimester products of conception compared with 2nd and 3rd trimester specimens (0.38% vs 0.09%; p < 0.0001). A total of 97 specimens were initially diagnosed with chronic intervillositis. 56 out of 97 (57.7%) specimens met our diagnostic criteria for CIUE on review. Pregnancies with confirmed CIUE had significantly higher rates of pregnancy loss compared with pregnancies with chronic intervillositis not meeting our study criteria for CIUE (94% vs 71%; p = 0.003). Pregnancy loss between low grade (42.9%; 24 out of 56 cases of CIUE) and high grade (57.1%; 32 out of 56 cases) CIUE were not significantly different. DISCUSSION: CIUE prevalence is low at 0.17%, but it is associated with pregnancy loss, particularly in the first trimester. High grade disease may be associated with worse pregnancy outcomes than low grade disease.

RESUMO

BACKGROUND: Idiopathic secondary recurrent miscarriage may be associated with an abnormal maternal immune response to subsequent pregnancies. Intravenous immunoglobulin (IVIG) has been studied in randomized controlled trials (RCTs) with conflicting results. Therefore, a definitive trial was proposed. METHODS: We conducted an investigator-initiated, multicentered, randomized, double-blinded, placebo-controlled trial comparing IVIG with saline in women with idiopathic secondary recurrent miscarriage, defined as a history of at least one prior ongoing pregnancy followed by three or more consecutive unexplained miscarriages. Subjects received either IVIG 500 mg/kg or the equivalent volume of normal saline. Preconception infusions were administered 14-21 days from the projected next menstrual period. With documentation of pregnancy, the subject received the same infusion every 4 weeks until 18-20 weeks of gestation. The primary outcome was an ongoing pregnancy of at least 20 weeks of gestation. RESULTS: A total of 82 patients enrolled, of whom 47 had an index pregnancy. All ongoing pregnancies resulted in live births. Therefore, the live birth rates were 70% (16/23) in the IVIG group and 63% (15/24) in the control group (P = 0.760); odds ratio (OR) 1.37 [95% confidence interval (CI) 0.41-4.61]. Including only clinical pregnancies (embryo with cardiac activity at 6 weeks of gestation), the live birth rates were equivalent, 94% (16/17) and (15/16), respectively (P > 0.999); OR 1.07 (95% CI 0.06-18.62). Meta-analysis of randomized controlled trials (RCTs) evaluating IVIG for idiopathic secondary recurrent miscarriage revealed live birth rates of 70% (31/44) in the IVIG group and 62% (28/45) in the control group (P = 0.503); common OR 1.44 (95% CI 0.59-3.48). CONCLUSIONS: This is the largest RCT to date in which IVIG was evaluated in women with idiopathic secondary recurrent miscarriage; no treatment benefit was found. The meta-analysis, which combined our study results with two prior RCTs, also showed no significant effect of treatment with IVIG.
