Corticosteroid or intravenous immunoglobulin is used in the management of idiopathic thrombocytopenic purpura during pregnancy.A patient with idiopathic thrombocytopenic purpura had a previous history of interrupted pregnancy due to severe thrombocytopenia, and was unresponsive to high doses of corticosteroids and intravenous immunoglobulin. Immediately following pregnancy, our patient had a marked elevation in plasma levels of fibrinogen degradation products, D-dimer, and platelet factor 4, with a decrease in platelets, suggesting platelet activation and thrombogenesis. Combined treatment with an anticoagulant agent could prevent exacerbation of thrombocytopenia throughout pregnancy. Although the underlying causes leading to the series in her pregnancy course were uncertain, there were notable serological abnormalities, such as weakly positive antinuclear antibody and anti-U1-RNP antibody.When thrombocytopenia rapidly develops in patients with idiopathic thrombocytopenic purpura immediately following pregnancy, the possibility of a thrombogenic state and differential diagnosis, including antiphospholipid syndrome and collagen vascular disease, should be considered. Treatment with an anticoagulant agent might then be appropriate.
Twin anemia-polycythemia sequence (TAPS) is characterized by large inter-twin hemoglobin value differences without inter-twin amniotic fluid discordance. The management of post-laser TAPS remains controversial. Hence, more studies on TAPS, together with the associated maternal complications and outcome of the fetuses and infants are needed. Between 2003 and 2012, we performed 287 cases of fetoscopic laser photocoagulation for twin-twin transfusion syndrome. Among the 114 who were placed under our care until delivery, three cases of TAPS occurred. In one case, we conducted intrauterine intravenous transfusion, while in the other two cases, we adopted expectant management. We performed an emergency caesarean section at 27-30 weeks of gestation in all cases due to a severe condition of anemia in the TAPS donor. Two cases with antenatal TAPS stage 4 had severe maternal complications; one had minute pulmonary embolism, while the other had Mirror syndrome. All three pairs of infants survived. One TAPS donor and one TAPS recipient had neurodevelopmental impairment; bilateral deafness at 9.5 years old and spastic paralysis at 2 years old, respectively. In conclusion, post-laser TAPS in a higher stage can cause severe maternal complications. Close observations for both fetuses and mothers are required for such cases.
Correlations among Chiari type II malformation (CMII) morphological findings, the proportion of fetal heart rate patterns corresponding to the quiet phase (QP), and neurological outcomes have yet to be investigated.The correlations among the morphological findings (i.e., the degree of ventriculomegaly, myelomeningocele levels, and degree of cerebellar herniation), proportion of time spent in QP, and developmental quotients (DQs) were analyzed in 22 children. The proportion of time spent in QP was compared between children with poor neurological outcomes (n = 9) and those with good outcomes (n = 13). Pearson's correlations and the Mann-Whitney U-test were used to assess for statistical significance; P < 0.05 was considered statistically significant. No significant differences were observed between the DQs and morphological findings, but the DQs and the proportion of time spent in QP were significantly correlated (r = 0.287, P = 0.01). The proportion of time spent in QP was significantly different between children with poor outcomes and those with good outcomes (median, 11% [range, 0-32%] vs. 28% [range, 2-55%]; P = 0.006).The proportion of fetal heart rate patterns corresponding to the QP might be a useful predictor of neurological outcomes in 2-year-old children with CMII.
Although pregnancies conceived by assisted reproductive technology (ART) have a higher risk of maternal/perinatal complications, the overall risk of adverse outcomes necessitating advanced obstetric care has not been closely examined. The present study aimed to assess and compare the risk of maternal/perinatal complications and adverse outcomes in pregnancy and childbirth conceived by ART with those conceived naturally.This study was conducted as a part of the Japan environment and children's study (JECS), an ongoing nationwide birth cohort study in Japan. The risk of maternal/perinatal complications and adverse outcomes was assessed by mode of conception (natural conception, ovulation induction [OI] without ART, conventional in vitro fertilization and embryo transfer [IVF-ET], or intracytoplasmic sperm injection [ICSI]) using logistic regression and generalized estimating equations controlling for potential confounders.The final dataset included women who conceived naturally (N = 90,506), by OI without ART (N = 3939), by conventional IVF-ET (N = 1476), and by ICSI (N = 1671). Compared with women who conceived naturally, those who conceived by conventional IVF-ET were at higher risk of placenta previa (adjusted OR 2.90 [95% CI 1.94, 4.34]), morbidly adherent placenta (6.85 [3.88, 12.13]), and pregnancy-induced hypertension (1.40 [1.10, 1.78]) whereas those who conceived by ICSI had a higher risk of placental abruption (2.16 [1.20, 3.88]) as well as placenta previa (2.01 [1.29, 3.13]) and morbidly adherent placenta (7.81 [4.56, 13.38]). Women who conceived by ART had a higher risk of blood transfusion (conventional IVF-ET: 3.85 [2.52, 5.88]; ICSI: 3.76 [2.49, 5.66]) and ICU admission (conventional IVF-ET: 2.58 [1.11, 6.01]; ICSI: 3.45 [1.68, 7.06]) even after controlling for potential confounders. Neonates conceived by ART had a higher risk of preterm birth (conventional IVF-ET: 1.42 [1.13, 1.78]; ICSI: 1.31 [1.05, 1.64]).Women who conceived by ART had a higher risk of maternal/perinatal complications necessitating advanced obstetric care. Obstetricians should be aware of the increased risk of adverse outcomes among this population.
Longitudinal hematological changes throughout twin pregnancies have not been reported. This study aimed to reveal longitudinal changes in hematological indices in twin pregnancies.
Abstract Chronic histiocytic intervillositis (CHI) is an extremely rare pathological condition but is strongly associated with severe obstetric complications and has a high recurrence rate. The management of this condition has not yet been established. We describe herein the occurrence of CHI in the late second–third trimester in each of three consecutive pregnancies in a single patient with four previous consecutive early miscarriages. In this patient, each of the three complicated pregnancies was managed with one of the following, respectively: low‐dose aspirin; heparin plus low‐dose aspirin; and prednisolone plus low‐dose aspirin. CHI was histologically confirmed in all three pregnancies, but the clinical results and pathology (e.g. extent of histiocytic infiltration) in each pregnancy clearly differed with treatment. Both combination treatments eventuated in a live birth. Immunosuppressive therapy seemed to produce better clinical results by restricting the extent of the affected areas. The elevated alkaline phosphatase associated with the CHI was assumed to have no clinical prognostic value.
