Inflammatory bowel disease (IBD) is a group of chronic, recurrent, and non-specific intestinal inflammatory diseases. It usually occurs between 20 and 40 years old, overlapping with the patient’s childbearing age. Active IBD may lead to decreased fertility and adverse pregnancy outcomes, and pregnancy may also lead to recurrence of IBD. Through studying domestic and foreign related literature on pregnancy and IBD, this article elaborates on the guidance and management of IBD before pregnancy, the disease management of IBD during pregnancy, the disease management of IBD during lactation, and the current status and prospects of traditional Chinese medicine treatment. It aims to provide references for patients and clinicians to have a more scientific understanding of pregnancy with IBD.
ObjectiveTo establish a normal reference value range of specific thyroid function in pregnant women corresponding to Beckman reagent in Chengdu.MethodsWe randomly selected 120 non-pregnant women and 445 pregnant women who underwent routine examinations at the First Affiliated Hospital of Chengdu Medical College from November 2016 to June 2017; tested for free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) in serum; used SPSS 24.0 to calculate the bilateral limit of each index (Section 2.5, 97. 5 Quot); established the normal range of Beckman reagent.ResultsThe reference ranges of FT3, FT4, and TSH in the first, second, and third trimester of pregnancy were 4.41–6.33, 4.17–6.12, and 3.86–6.39 pmol/L; 7.64–14.63, 6.62–13.69, and 6.62–12.51 pmol/L; 0.21–3.62, 0.16–4.35, and 0.89–4.88 mU/L; respectively. There was no significant difference in serum TSH between the first and second trimester (P>0.05), and neither between the first and second trimesters and the controls in serum FT3 (P>0.05). The differences in serum FT3, FT4, and TSH among the rest of trimesters, and between each trimester and the normal control group were statistically significant (P<0.05). There was a significant correlation between TSH and FT4 in the early and middle stages of pregnancy (r=–0.277, –0.392, P<0.01).ConclusionThe reference value of FT3, FT4, and TSH in pregnant women with Beckman reagent was significantly different from that in non-pregnant women.
ObjectiveTo systematically review the association between maternal folate supplementation during pregnancy and the risk of autism spectrum disorder (ASD) in the offspring.MethodsPubMed, EMbase, Web of Science, The Cochrane Library, Scopus, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect case-control and cohort studies on the association between maternal folate supplementation during pregnancy and the risk of ASD in the offspring from inception to December 2020. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 and Stata 14.0 software.ResultsA total of 17 studies involving 10 812 cases and 876 241 controls were included. The results of meta-analysis showed that there was no significant association between maternal folate supplementation during pregnancy and the risk of ASD in the offspring in the total population. The subgroup analysis revealed that maternal folate supplementation during pregnancy was statistically associated with a reduced risk of ASD in the offspring in the Asian population (OR=0.71, 95%CI 0.53 to 0.96, P=0.03). However, there were no statistical correlations in European and American populations.ConclusionsCurrent evidence shows that maternal folate supplementation during pregnancy may reduce the risk of ASD in the offspring in the Asian population. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
Objective To investigate the clinical characteristics and treatment of severe H1N1 influenza during pregnancy and postpartum.Methods Clinical data of 7 pregnant women and 2 postpartum women with severe H1N1 influenza admitted from October to December 2009 were reviewed. Results Three pregnant women underwent caesarean section during hospitalization. The main symptoms included fever ( in9 cases, and fever lasted more than 3 days in 7 cases) , cough and sputum ( in 9 cases) , and dyspnea ( in 7 cases) . Asthenia and muscular soreness were not serious, and there were no accompanying symptoms of digestive tract. Moist rales were heard in 5 cases. White blood cell count decreased in 3 cases, neutrophils increased in 6 cases, and lymphocytes reduced in 7 cases. Hepatic enzymes were abnormal in 4 cases, and myocardial enzymes were abnormal in5 cases. 8 patients had hypoxemia, with PaO2 less than 40 mmHg in5 cases. Chest X-ray films and CT showed double pneumonia in 9 patients. 9 patients were given oseltamivir antiviral treatment. 8 cases were given antibiotic therapy. 5 patients with bilateral severe pneumonia and respiratory failure were given corticosteriod therapy. 5 severe patients were treated with non-invasive ventilation. One case switched to invasive ventilation and eventually died. Conclusions Pregnant and postpartum women with influenzaH1N1 are likely to develop into severe condition which is commonly rapidlyprogressive and even life-threatening. The main causes of death are pneumonia and acute respiratory distress syndrome.
ObjectiveTo explore the predictors of seizures during pregnancy, and to explore whether seizure control in the 6 months and 1 year prior to pregnancy can predict the risk of seizures during pregnancy and the occurrence of adverse maternal and infant outcomes, so as to guide the choice of the best fertility timing for women with epilepsy (WWE).MethodsA total of 46 WWE with 48 pregnancies were enrolled in Epilepsy Clinics of Tianjin Medical University from August 2016 to January 2020. Retrospective analysis was used to analyze the risk factors of epileptic seizures in pregnancy. The patients were grouped according to the time of absence of seizures during pregnancy. To analyze the influence of epileptic seizure, pregnancy complications and pregnancy outcome.Results Among 48 pregnancies, the risk of premature rupture of membranes was significantly higher in patients with epilepsy than those without epilepsy (34.6% vs. 0.0%), and the difference was statistically significant (P<0.01). There was no significant difference in the risk of PIH, GDM, gestational anemia and pregnancy complications (P>0.05). For women who had seizure during pregnancy, the mean birth weight of the offspring was slightly lower, and the incidence of low birth weight and fetal distress was higher, but the difference was not statistically significant (P>0.05); Seizures in the 6 months before pregnancy were significantly associated with seizures during pregnancy [RR=4.28, 95%CI (2.10, 8.74), P<0.01]. Further, the risk of adverse pregnancy outcomes increased significantly [RR=2.00, 95%CI (1.10, 3.65), P<0.05] for WWE who had seizure in 6 month before pregnancy; The rates of seizures during pregnancy in the two groups were 25.0% and 20.0%, but the difference was not statistically significant (P>0.05). Compared with the 6-months, the ≥1 year group had a lower risk of PIH and gestational anemia, and the offspring had a lower risk of low birth weight, premature delivery and fetal distress, but the difference was not statistically significant (P>0.05).ConclusionEnsuring seizure-free at least 6 months before pregnancy will significantly reduce the probability of seizures during pregnancy, and is significantly associated with a lower incidence of adverse pregnancy outcomes. Women of childbearing age with epilepsy are advised to plan pregnancy after reaching seizure-free at least 6 months.
ObjectiveTo discuss the risk of abortion related to lamotrigine (LTG) and its safety profile during pregnancy. MethodsRetrospectively studied pregnant women in our epilepsy clinics who took LTG from 2011 to 2015 as monotherapy and experienced embryo damage or abortion. Here, we present an extensive review of related literatures regarding possible mechanisms, clinical features and safty of LTG during pregnancy. ResultsIn our study, fourty-five pregnancies were administered monotherapy LTG, and three of these patients suffered embryo damage. ConclusionsAlthough LTG is considered safe for pregnant women and the embryo or fetus,it also has risk of embryo damage or abortion, which should be carefully considered before prescription. Using monotherapy and the lowest effective drug dose, monitoring LTG serum concentrations during pregnancy, supplementing folate administration before and after conception and conducting regular prenatal diagnostic tests might reduce the risk of abortion.
Objective To study the advances in research of breast cancer during pregnancy. Methods The literatures in recent years were reviewed. Results A lot of evidences suggested that the diagnosis may be delayed easily. The diagnosis was primarily made by needle aspiration cytology and biopsy. The treatment of pregnant breast cancer was not different from ordinary breast cancer, however the factor of foetus should be taken into account. Termination of pregnancy did not improve survival. Conclusion Pregnant breast cancer is mostly at later stage at the time of diagnosis and has poorer prognosis than ordinary breast cancer. The patients with breast cancer during pregnancy usually have an equivalent survival rate when compared with age and stagematched ordinary group. Future pregnancy may be allowed after two years of treatment in patients with early breast cancer.
Objective To study the influence of hyperlipemia on rats with acute pancreatits during pregnancy and its mechanism. Methods Seventy two pregnant Sprague-Dawley rats were randomly divided into the test group and the control group， and then they were fed with high fat diet and balanced diet for 16 days separately. Pregnant rats were given intraperitoneal injection with L-arginine for 2 times (one time is 250 mg/100 g, the other is 200 mg/100 g) at an interval of 1 h. The serum triglyceride (TG), serum amylase (AMS), and lipase (LPS) from blood samples were tested just after injection, and 12 h， 18 h， 24 h， 30 h and 48 h after injection respectively, and wet/dry ratio of pancreas were measured. The histopathological score of pancreatic tissue was evaluated based on microscopic changes, and the expression of TNF-α protein was determined by SP immunohistochemical technique. Results After the last injection, the level of TG in the test group was obviously higher than that in the control group in each time (P＜0.05). The peak values of AMS and LPS in the test group appeared at 24， 18 h respectively, while the peaks appeared at 30， 24 h in the control group, respectively, which were significantly lower than those in the test group (P＜0.05). Compared with the control group, the wet/dry ratio of pancreas in the test group increased at 12, 18 and 24 h after injection (P＜0.05); The pathological changes of pancreas in test group was more serious with higher histopathological score at 0, 12, 18 and 24 h (P＜0.05), and expression of the TNF-α protein was higher at 12, 18 and 24 h (P＜0.05), too. Conclusion Hyperlipemia can make L-arginine-induced-acute-pancreatitis during pregnancy earlier occur and lead to more serious injury in pancreas. This study demonstrates that hyperlipemia may be a high risk factor for acute pancreatitis during pregnancy, making a great amount of free fatty acid released from TG and up-regulated the expression of TNF-α.
ObjectiveTo explored the influence of disease changes, weight gain, eosinophil levels and other factor in pregnancy women with asthma. MethodsCase records of gestational asthma patients produced in the obstetrics department of Peking University People's Hospital from October 2010 to October 2020 were collected, and refer to electronic medical records of clinics (pre-pregnancy and pregnancy). According to the disease control (asthma related unplanned respiratory clinics, emergency or hospitalization), patients were divided into pregnancy stable group and pregnancy fluctuation group. The basic characteristics, pre-pregnancy asthma control, weight gain during pregnancy and peripheral blood eosinophil level before labor were retrospectively analyzed. The cause of asthma attacks, clinical characteristics and distribution of gestational time in pregnancy fluctuations were described. Peripheral blood eosinophil levels in different period during pregnancy in the stable group were analyzed. ResultsTotally 124 cases of natural pregnancy singleton were enrolled in the study. The age was (32.3±3.9) years old. There were 71 patients in stable group and 53 patients in fluctuation group. The proportion of pre-pregnancy instability in the fluctuating pregnancy group was higher than that in the stable pregnancy group (P<0.05). The proportion of intermittent medication before pregnancy was higher in the fluctuating pregnancy group than in the stable pregnancy group (P<0.05). Peripheral blood eosinophil count before labor and the number of cases with eosinophil count≥0.15×109/L before labor were higher in the fluctuation group (all P<0.05). The proportion of hypertentive diseases in pregnancy and fetal distress in uterus were higher in the fluctuation group (all P<0.05). The common cold was the common trigger factor (38.2%) and asthma recurrences occur between 13 and 36 weeks of gestation (65.8%) in fluctuation group. In further analysis of subgroup (the stable group), peripheral blood eosinophil count in early pregnancy (P<0.05) and pregnant metaphase (P<0.05) were higher than before delivery. The number of cases with eosinophil count>0.15×109/L in pregnant metaphase (P<0.05) was higher than before delivery. ConclusionsAsthma fluctuates during pregnancy is associated with adverse maternal and fetal outcomes. It is very important and critical that asthma control before pregnancy, weight gain management and eosinophil level monitoring of patients with asthma during pregnancy. The whole management is imperative in women with asthma during pregnancy.
ObjectiveTo investigate the clinical characteristics of epileptics with pregnancy and then provide reference for standardized management of epileptics with pregnancy. MethodsFrom June 2012 to June 2021, epileptics with pregnancy who delivered in Jinan Central Hospital were selected as the research subjects. The clinical data such as the application of Antiseizure medications (ASMs) during pregnancy, seizure frequency, pregnancy outcomes, delivery ways, offspring feeding ways and the incidence of complications were investigated and analyzed. ResultsAmong 36 epileptics with pregnancy, 20 cases (55.56%) were treated with ASMs alone, 5 cases (13.88%) were treated with combined medication, and 11 cases (30.56%) were treated without ASMs during pregnancy. 15 cases (41.67%) adhered to systematic application of ASMs, 17 cases (47.22%) did not adhere to systematic application of ASMs, and 4 cases (11.11%) had unknown medication history. The frequency of seizures increased in 5 cases, decreased in 7 cases and unchanged in 24 cases during pregnancy. Pregnancy outcomes: full-term delivery in 33 cases (91.67%), preterm delivery in 1 case (2.78%) and abortion in 2 cases (5.56%). Delivery mode: cesarean section in 31 cases (91.18%), vaginal delivery in 3 cases (8.82%). After delivery, 4 cases (11.76%) were fed with milk powder and 30 cases (88.24%) were breast-fed. Complications: There were 6 cases complicated with anemia (16.67%), 5 cases complicated with gestational hypertension (13.89%), 3 cases complicated with gestational diabetes (8.33%), 4 cases complicated with premature rupture of membranes (11.11%), 2 cases complicated with fetal growth restriction (5.56%), 2 cases complicated with oligohydramnios (5.56%), 3 cases complicated with fetal distress (8.33%) and 3 cases complicated with neonatal asphyxia (8.33%). ConclusionsThe proportion of epileptics with pregnancy who were systematically treated with ASMs was low and the seizures were poorly controlled. There is a lack of standardized management for such patients in clinical practice.
