Prediction of preeclampsia in type 1 diabetes in early pregnancy by clinical predictors: a systematic review

Purpose: The purpose of this study is to evaluate the prevalence and possible clinical predictors of preeclampsia present in early pregnancy among women with type 1 diabetes.

Methods: A systematic search of PubMed was conducted in April 2017. Inclusion criteria were largely unselected cohort, including at least 100 women with type 1 diabetes, dealing with either the prevalence of preeclampsia or possible clinical predictors of preeclampsia identified in early pregnancy.

Results: Based on 11,518 pregnancies in 11 articles, the prevalence of preeclampsia in women with type 1 diabetes was 17%, five to six times more than in the background population. In early pregnancy, the following clinical predictors were associated with increased prevalence of preeclampsia: diabetic nephropathy (OR 3.7–23.5), microalbuminuria (OR 3.8–11.7), diabetic retinopathy (OR 1.9–2.9) and pre-existing hypertension (OR 3.8–17.1) as well as high blood pressure within the normotensive range. HbA1C, body mass index and nulliparity were positively associated with preeclampsia, but not consistently.

Conclusion: The prevalence of preeclampsia in women with type 1 diabetes was 17%. In early pregnancy pre-existing hypertension and high blood pressure within the normotensive range as well as presence of microangiopathy were predictors of preeclampsia. Poor glycaemic control, obesity and nulliparity probably also contribute to the increased risk.     

Primary omental pregnancy: case report and review of literature

Omental pregnancy is a very rare form of ectopic pregnancy. A 29-year-old woman presented with severe abdominal pain. History of the patient revealed use of combined oral contraceptive pills. There was no gestational sac in the endometrial cavity and no tubal ring in the adnexa, but free peritoneal fluid was detected at ultrasonography. Laparotomy was done according to pre-operative diagnosis of ruptured tubal pregnancy. Bilateral tubes and ovaries were intact; gestational sac was detected attached to the necrotic lower edge of omentum. Although 16 cases of omental pregnancy (mostly secondary) were reported in the literature, herein we describe a primary omental pregnancy without adnexal involvement.     

Recurrent retroperitoneal myxoid liposarcoma during pregnancy: a case report and literature review

Retroperitoneal liposarcoma in pregnancy is rare, and only a few cases of primary liposarcoma during pregnancy have been reported. To the best of our knowledge, there is no published report of retroperitoneal liposarcoma that was previously treated and recurred during pregnancy. Our patient was diagnosed with a pelvic mass on ultrasound at 12-weeks' gestation. The mass was found to be a retroperitonal, well-differentiated myxoid liposarcoma and was radically excised at the time of cesarean delivery at 36-weeks' gestation. However, the tumor recurred soon and progressed rapidly, and the patient eventually died of the disease. A thorough sonographic investigation and timing of surgery may be critical in terms of finding a surgically resectable lesion and leading to a more favorable prognosis.

Maternal BMI and HDL as predictors of pregnancy outcome in women with type 1 diabetes

Abstract

Objective: Diabetes in pregnancy is associated with increased risks of maternal as well as foetal complications.

Methods: Retrospective data on 96 women and their 96 newborns were anonymously statistically analysed to assess pregnancies of type 1 diabetes (T1D) women managed in our hospital in past nine years. The outcomes of the neonates were divided into three categories according to the clinical status, presence of congenital abnormalities and infant’s treatment.

Results: We found out that the outcome of newborn infants associated with maternal HbA1c before gestation as well as during the whole course of pregnancy (p?<?0.02 for all). Surprisingly, neonatal outcome was strongly associated with the maternal BMI (p?<?0.05). In our model, a lowering of BMI by one grade led to an 18% increase in the chance that the newborn will have no health problems. We did not observe an important worsening of chronic diabetic complications in mothers; however, regarding maternal clinical status, we found that preeclampsia occurrence was strongly and independently connected to HDL level (p?<?0.01).

Conclusion: Our data demonstrate that lower pregestational BMI could substantially improve T1D mothers' pregnancy outcome. Lower HDL levels in T1D mothers during pregnancy correlate with higher risk of preeclampsia development.     

Benefits, risks, costs, and patient satisfaction associated with insulin pump therapy for the pregnancy complicated by type 1 diabetes mellitus

OBJECTIVE: Glycemic control, perinatal outcome, and health care costs were evaluated among women with type 1 diabetes mellitus who began insulin pump therapy during pregnancy (group 1, n = 24), were treated with multiple insulin injections (group 2, n = 24), or were already using an insulin pump before pregnancy (group 3, n = 12). Patient satisfaction and continuation of pump therapy post partum were assessed. STUDY DESIGN: A retrospective review of maternal and neonatal medical records was performed, and a questionnaire was sent to patients after delivery. Patients in groups 1 and 2 were matched for age, age at onset and duration of diabetes mellitus, White class, and date of delivery. RESULTS: No differences in glycosylated hemoglobin A levels were observed among groups 1, 2 or 3 in the first, second, or third trimester. Patients in group 1 started pump therapy at a mean of 16.8 weeks' gestation, and 17 (70.8%) began therapy as outpatients. No deterioration in glycemic control was noted during the 2- to 4-week period after the start of pump treatment. Among the women in group 1 eight had at least one episode of severe hypoglycemia before starting pump therapy, but only one had such an episode after this treatment was begun. Two episodes of ketoacidosis occurred in group 1, and no episodes occurred in groups 2 and 3. No significant differences in perinatal outcomes or health care costs were observed among groups 1, 2, and 3. After delivery 94. 7% of the women in group 1 continued to use the pump because it provided better glycemic control and a more flexible lifestyle. Postpartum glycosylated hemoglobin A values were 7.2% in group 1 and 9.1% in group 2, a significant difference. CONCLUSIONS: Insulin pump therapy was initiated during pregnancy without a deterioration of glycemic control and was associated with maternal and perinatal outcomes and health care costs comparable to those among women who were already using the pump before pregnancy or who received multiple-dose insulin therapy. Women who began pump therapy in pregnancy were highly likely to continue pump use after delivery and preferred the flexible lifestyle that this treatment allowed.     

Pregestational type 2 diabetes and gestational diabetes exhibit different sexual steroid profiles during pregnancy

Higher androgen levels are observed in non-pregnant women with diabetes. Whether this hormonal profile is found during pregnancy is unknown. The aim of this study was to determine the sexual steroids levels in pregnant women with pregestational type 2 (T2D) and gestational diabetes (GD) compared to healthy control (C) pregnant women during the second half of pregnancy. A prospective study of 69 pregnant women with T2D (n?=?21), GD (n = 24) and control (C, n?=?24) was followed up during the second half of gestation. Clinical assessments and blood samples were collected at 26.7 (25–27.8); 34 (32–34.9) and 37.5 (37–40) weeks of gestation. Androgens, sex hormone-binding globulin (SHBG), estrogens, estradiol/testosterone (E/T) ratio, insulin, glucose, HOMA-IR, were measured. Testosterone, insulin and homeostatic model assessment of insulin resistance (HOMA-IR) levels were higher in T2D compared with C at each sampling point during pregnancy, even after adjusting for BMI and age. Estrogens levels and estradiol/testosterone ratio were lower in T2D and GD compared with C. Hyperandrogenemia, and higher insulin resistance is observed in T2D, but not in GD during pregnancy. Decreased estrogen and E/T ratio found in T2D and GD suggests a diminished aromatase activity during gestation. T2D and GD are associated with specific changes in sexual steroids and insulin resistance levels during pregnancy.

Insulin therapy for the treatment of type 1 diabetes during pregnancy

Abstract

Pregnancies affected by type 1 diabetes (T1D) carry a major risk for poor fetal, neonatal and maternal outcomes. Achieving normoglycemia while minimizing the risk of hypoglycemia is a major goal in the management of T1D as this can greatly reduce the risk of complications. However, maintaining optimal glucose levels is challenging because insulin requirements are not uniform throughout the course of the pregnancy. Over the past decade, there has been significant improvement in the methods for glucose monitoring and insulin administration, accompanied by an increase in the number of treatment options available to pregnant patients with T1D. Through study of the scientific literature and accumulated evidence, we review advances in the management of T1D in pregnancy and offer advice on how to achieve optimal care for the patient.     

Myelomeningocele and pregnancy: a case report and review of the literature

The improvement of antenatal management and surgical techniques has greatly increased the survival rate of infants with spina bifida. More of these women are reaching adulthood and reproductive age and therefore could become pregnant. Pregnancy complications depend on the kind of spina bifida and subject’s condition.We report a case of woman with a severe kyphoscoliosis, that progressively affects lung capacity until 32 weeks of gestation, when she underwent caesarean section.These patients deserve careful obstetric care, genetic counselling and urological, obstetric, neurological and anaesthetic management.     

Pre-existing type I and type II diabetes in pregnancy

Diabetes mellitus is a long term chronic condition. The prevalence of diabetes in pregnancy is 2–5% in the UK of both gestational diabetes and pre-existing diabetes. The pregnancy outcomes for pre-existing type I and type II diabetic women are worse than for non-diabetic mothers. There is a higher incidence of stillbirth, macrosomia and congenital malformations. Pre-pregnancy counselling is essential to prepare for pregnancy, to tighten glycaemic control and review medication prior to pregnancy. Multi-disciplinary care is required throughout the antenatal period, to optimise blood glucose monitoring and control. Screening for diabetic complications such as nephropathy and retinopathy is necessary at every trimester to detect progression of disease. The timing, mode and management of delivery with a plan to maintain glycaemic control during this time should be discussed by 36 weeks. After completion of 38 weeks' gestation, induction of labour may be considered. This review will discuss the management of pre-existing type I and type II diabetic women from the preconception period to the postpartum period.     

Attitudes towards preconception care in Maltese women with type 1 diabetes mellitus

Introduction: The aim of this study was to assess the level of knowledge and awareness related to preconception care among Maltese women of reproductive age with type 1 diabetes mellitus (T1DM). Methods: Thirty-seven T1DM women, aged 12–30 years, were self-administered a questionnaire related to diabetes self-management and preconception care. The participants then underwent an educational intervention and re-took the same questionnaire. Results: Before the intervention, 26 participants (70%) claimed they did not have any knowledge about the preconception care of diabetes. Of the remaining 11 participants, the main reported source of information about diabetes care was the diabetologist (n = 8; 6.7%). The response rate was 70% (26 out of 37 participants completed the questionnaire after the educational intervention). Six of the participants who initially reported no preconception care knowledge claimed an increased awareness after the event. There was a statistically significant increase in the knowledge scores after the intervention. Conclusion: It is evident that there is a lack of awareness of the importance of pre-pregnancy planning to avoid pregnancy-related complications with diabetes. This emphasizes the need for more education and it is imperative for healthcare professionals to address these issues with adolescent female patients.     

An arteriovenous malformation in pregnancy: a case report and review of the literature

A case is described of a young woman with progression of a macrofistulous arteriovenous malformation during pregnancy. This resulted in severe symptoms necessitating cesarean section, following which there was a dramatic postpartum recovery. The arteriovenous malformation was confirmed by angiography. The literature related to arteriovenous malformations in pregnancy is reviewed.     

Ovarian ectopic pregnancy after ICSI-ET: a case report and literature review

INTRODUCTION: Primary ovarian ectopic pregnancy (OEP) is one of the the rarest form of extratubal pregnancies and its pathophysciological mechanism is not fully understood. On the other hand, OEP after intra-cytoplasmic sperm injection with embryo transfer (ICSI-ET) is even more rare and just a few cases have been reported in literature. MATERIALS AND METHODS: A case with OEP after ICSI-ET presented and managed by conservative laparoscopic approach. Also, literature associated with OEP after ICSI-ET have been summarized. Pubmed search using "Ovarian ectopic pregnancy" and "ICSI-ET" keywords revealed four similar case in the literature. CONCLUSION: Underlying pathophysiological mechanism of OEP after ICSI-ET is unclear. Indeed, gynecologists should be aware about the development of the OEP after ICSI-ET. Early diagnosis will give the opportunity to use conservative managements for these infertile patients.     

Pheochromocytoma in neurofibromatosis type 1 during pregnancy

Pregnant women with neurofibromatosis type 1 (NF-1) have increased complications during gestation, including hypertensive disorders that are sometimes caused by pheochromocytoma. Pheochromocytoma is an extremely rare condition during pregnancy, and the main clinical manifestation is hypertension. If not properly treated, pheochromocytoma has high maternal and fetal mortality rates. Early recognition and adequate clinical management before delivery have led to better outcomes in the last few decades. Despite the association of NF-1 and pheochromocytoma, there are few clinical reports of these two conditions in pregnant patients. We present a rare case of pheochromocytoma diagnosed during pregnancy in a patient with NF-1, and we describe the treatment and the obstetric and fetal outcomes. We also review other medical conditions related to NF-1 that complicated this patient’s pregnancy.
