Detemir vs neutral protamine Hagedorn insulin for diabetes mellitus in pregnancy: a comparative effectiveness, randomized controlled trial. Am J Obstet Gynecol 2021; 225:87.e1-87.e10. [PMID: 33865836 DOI: 10.1016/j.ajog.2021.04.223] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 04/06/2021] [Accepted: 04/08/2021] [Indexed: 01/24/2023]
Abstract
BACKGROUND Insulin detemir, being used increasingly during pregnancy, may have pharmacologic benefits compared with neutral protamine Hagedorn. OBJECTIVE We evaluated the probability that compared with treatment with neutral protamine Hagedorn, treatment with insulin detemir reduces the risk for adverse neonatal outcome among individuals with type 2 or overt type 2 diabetes mellitus (gestational diabetes mellitus diagnosed at <20 weeks' gestation). STUDY DESIGN We performed a multiclinic randomized controlled trial (September 2018 to January 2020), which included women with singleton gestation with type 2 or overt type 2 diabetes mellitus who sought obstetrical care at ≤21 weeks' gestation. Participants were randomized to receive either insulin detemir or neutral protamine Hagedorn by a clinic-stratified scheme. The primary outcome was a composite of adverse neonatal outcomes, including shoulder dystocia, large for gestational age, neonatal intensive care unit admission, respiratory distress (defined as the need of at least 4 hours of respiratory support with supplemental oxygen, continuous positive airway pressure or ventilation at the first 24 hours of life), or hypoglycemia. The secondary neonatal outcomes included gestational age at delivery, small for gestational age, 5-minute Apgar score of <7, lowest glucose level, need for intravenous glucose, respiratory distress syndrome, need for mechanical ventilation or continuous positive airway pressure, neonatal jaundice requiring therapy, brachial plexus injury, and hospital length of stay. The secondary maternal outcomes included hypoglycemic events, hospital admission for glucose control, hypertensive disorder of pregnancy, maternal weight gain, cesarean delivery, and postpartum complications. We used the Bayesian statistics to estimate a sample size of 108 to have >75% probability of any reduction in the primary outcome, assuming 80% power and a hypothesized effect of 33% reduction with insulin detemir. All analyses were intent to treat under a Bayesian framework with neutral priors (a priori assumed a 50:50 likelihood of either intervention being better; National Clinical Trial identifier 03620890). RESULTS There were 108 women randomized in this trial (57 in insulin detemir and 51 in neutral protamine Hagedorn), and 103 women were available for analysis of the primary outcome (n=5 for pregnancy loss before 24 weeks' gestation). Bayesian analysis indicated an 87% posterior probability of reduced primary outcome with insulin detemir compared with neutral protamine Hagedorn (posterior adjusted relative risk, 0.88; 95% credible interval, 0.61-1.12). Bayesian analyses for secondary outcomes showed consistent findings of lower adverse maternal outcomes with the use of insulin detemir vs neutral protamine Hagedorn: for example, maternal hypoglycemic events (97% probability of benefit; posterior adjusted relative risk, 0.59; 95% credible interval, 0.29-1.08) and hypertensive disorders (88% probability of benefit; posterior adjusted relative risk, 0.81; 95% credible interval, 0.54-1.16). CONCLUSION In our comparative effectiveness trial involving individuals with type 2 or overt type 2 diabetes mellitus, use of insulin detemir resulted in lower rates of adverse neonatal and maternal outcomes compared with neutral protamine Hagedorn.

Abstract
Aims: To map health practitioners' experiences and describe knowledge regarding screening and management of Diabetes in Pregnancy (DIP) in Far North Queensland, Australia. Methods: Mixed methods including a cross-sectional survey (101 respondents) and 8 focus groups with 61 health practitioners. All participants provided clinical care for women with DIP. Results: A wide range of healthcare professionals participated; 96% worked with Indigenous women, and 63% were from regional or remote work settings. Universal screening for gestational diabetes at 24-28 weeks gestation was reported as routine with 87% using a 75 g Oral Glucose Tolerance Test. Early screening for DIP was reported by 61% although there was large variation in screening methods and who should be screened <24 weeks. Health practitioners were confident providing lifestyle advice (88%), dietary, and blood glucose monitoring education (67%, 81%) but only 50% were confident giving insulin education. Electronic medical records were used by 80% but 55% also used paper records. Dissatisfaction with information from hospitals was reported by 40%. In the focus groups improving communication and information technology systems were identified as key areas. Other barriers described were difficulties in care coordination and access for remote women. Conclusions: Communication, information technology systems, coordination of care, and education for health professionals are key areas that will be addressed by a complex health systems intervention being undertaken by the DIP Partnership in North Queensland.

Abstract
Maternal obesity during pregnancy may influence fetal development and possibly predispose offspring to cardiovascular disease. The aim of the present study was to evaluate the relationship between maternal pre-pregnancy body mass index (BMI) and weight gain during pregnancy, and newborn birth weight, with lipid profile, high-sensitivity C-reactive protein (hs-CRP) and leukocyte in newborns. We performed a cross-sectional study of 245 mothers and their children. Blood was collected from the umbilical vein and assayed for lipid profile, hs-CRP and leukocyte count. Newborns average weight was 3241 g, total cholesterol 53.9 mg/dl, high-density lipoprotein cholesterol (HDL-c) 21.9 mg/dl, low-density lipoprotein cholesterol (LDL-c) 26.2 mg/dl, triglyceride 29.5 mg/dl and leukocytes 13,777/mm3. There was a direct correlation of pre-pregnancy BMI of overweight mothers with total cholesterol (r=0.220, P=0.037) and LDL-c (r=0.268, P=0.011) of newborns. Total cholesterol, LDL-c and HDL-c were higher in pre-term newborns (66.3±19.7, 35.9±14.6 and 25.2±7.7 mg/dl, respectively) that in full-term (52.4±13.1, 25.0±8.7 and 21.5±6.0 mg/dl), with P=0.001, 0.001 and 0.003, respectively. Leukocyte counts were higher in full-term newborns (14,268±3982/mm3) compared with pre-term (9792±2836/mm3, P<0.0001). There was a direct correlation between birth weight and leukocyte counts of newborns (r=0.282, P<0.0001). These results suggest the possible interaction of maternal weight and fetal growth with lipid metabolism and leukocyte count in the newborn, which may be linked to programming of the immune system.

Abstract
Assessment of perinatal effects of drug exposure during pregnancy after approval is an important issue for regulatory agencies. The study aimed to explore associations between perinatal outcomes and maternal exposure to drugs for chronic diseases, including hypertension, diabetes, and autoimmune disease.We reviewed 521 cases of adverse reactions due to drug exposure during pregnancy who were reported to the Pharmaceuticals and Medical Devices Agency, a regulatory authority in Japan. The primary outcomes were fetal and neonatal death and malformation of infants. Associations between perinatal outcomes and exposure to each drug category for hypertension, diabetes, and autoimmune disease were evaluated using logistic regression analysis.Of the 521 cases (maternal age: 15-47 years; mean 32.3 ± 5.5), fetal and neonatal deaths were reported in 159 cases (130 miscarriage; 12 stillbirth; 4, neonatal death; and 13 abortion due to medical reasons), and malformations of infants were observed in 124 cases. In contrast to the trend of association between diabetes with or without medication and fetal and neonatal death (odds ratio [OR], 0.49; 95% confidence interval [CI], 0.17-1.36), exposure to oral antidiabetics tended to be associated with fetal and neonatal death (OR, 4.86; 95% CI, 0.81-29.2). Malformation tended to be correlated with exposure to angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (OR, 2.98; 95% CI, 0.76-11.7). This association showed trends opposite to that of the association with hypertension itself (OR, 0.42; 95% CI, 0.18-1.02) or overall antihypertensives (OR, 0.42; 95% CI, 0.15-1.13). Occurrence of multiple malformations was associated with exposure to biologics (OR, 8.46; 95% CI, 1.40-51.1), whereas there was no significant association between multiple malformations and autoimmune disease with or without medication (OR 1.07; 95% CI, 0.37-3.06).These findings suggest that drugs of different categories may have undesirable effects when used during pregnancy. However, the regulatory database was not originally designed to evaluate the causal associations between drug exposure and adverse drug reactions. The limitations of spontaneous reporting systems should be carefully taken into account. Further studies are needed to elucidate the effects of individual drugs in each category on perinatal outcomes.

Abstract
BACKGROUND It is crucial to identify in large population samples the most important determinants of excessive fetal growth. The aim of the study was to evaluate the independent role of pre-pregnancy body mass index (BMI), gestational weight gain and gestational diabetes on the risk of macrosomia. METHODS A prospective study collected data on mode of delivery and maternal/neonatal outcomes in eleven Hospitals in Italy. Multiple pregnancies and preterm deliveries were excluded. The sample included 14109 women with complete records. Associations between exposure variables and newborn macrosomia were analyzed using Pearson's chi squared test. Multiple logistic regression models were built to assess the independent association between potential predictors and macrosomia. RESULTS Maternal obesity (adjusted OR 1.7, 95% CI 1.4-2.2), excessive gestational weight gain (adjusted OR 1.9, 95% CI 1.6-2.2) and diabetes (adjusted OR 2.1, 95% CI 1.5-3.0 for gestational; adjusted OR 3.0, 95% CI 1.2-7.6 for pre-gestational) resulted to be independent predictors of macrosomia, when adjusted for other recognized risk factors. Since no significant interaction was found between pre-gestational BMI and gestational weight gain, excessive weight gain should be considered an independent risk factor for macrosomia. In the sub-group of women affected by gestational or pre-gestational diabetes, pre-gestational BMI was not significantly associated to macrosomia, while excessive pregnancy weight gain, maternal height and gestational age at delivery were significantly associated. In this sub-population, pregnancy weight gain less than recommended was not significantly associated to a reduction in macrosomia. CONCLUSIONS Our findings indicate that maternal obesity, gestational weight gain excess and diabetes should be considered as independent risk factors for newborn macrosomia. To adequately evaluate the clinical evolution of pregnancy all three variables need to be carefully assessed and monitored.

Abstract
Werner's syndrome (WS) is a rare autosomal recessive disorder, characterised by skin changes prematurely during adolescence. An unusual case of WS was found in a 27-year-old pregnant woman who presented to the hospital with a history of uncontrolled hypertension at 32 weeks of gestation. All clinical features corresponding to WS (early aging of skin, hair loss, blurred vision and diabetes type 2) appeared to match with the prospective diagnosis, which was confirmed later with genetic testing. The pregnancy became complicated due to oligohydramnios and therefore a caesarean section was carried out in order to preserve the fetus. Despite all implemented efforts, the patient died intraoperative as a result of cardiac arrest and its complications. Successfully, the newborn survived and it was further investigated to exclude this condition.

Abstract
BACKGROUND/AIMS The use of glycated hemoglobin (HbA1c) measurement in gestational diabetes mellitus (GDM) is controversial. Aim of the present study was to determine HbA1c levels in a series of GDM patients, in order to verify the possible contribution of HbA1c to GDM management. MATERIALS/SUBJECTS AND METHODS The study included 148 caucasian GDM patients. GDM screening was performed between the 24th and the 28th week of gestation by a two-step procedure, according to the 4th and 5th International Workshop Conference on Gestational Diabetes Mellitus recommendations. Exclusion criteria were: preexisting diabetes, corticosteroid therapy, history of asthma or hypertension, known fetal anomaly, history of previous stillbirth, preterm delivery considered to be likely for either maternal disease or fetal conditions. HBA1c was determined by a standard HPLC technique. RESULTS At GDM diagnosis, all HbA1c levels were ≤ 6% and the greatest frequency (71/148; 48.0%) of HbA1c values resulted in the range 5.0-5.3%. This frequency increased to 54% before delivery. A significant correlation between HbA1c values at GDM diagnosis and individual BMI prior to conception was observed. The proportion of pregnancies presenting negative outcomes increased progressively with increasing HbA1c levels, from 6.2% (1/16) for HbA1c levels <5% to 18.3% (13/71) for HbA1c 5.0-5.3%, to 37.8% (17/45) in patients with HBA1c levels 5.4-5.6%, to 56.2% (9/16) for HbA1c levels >5.6%. ROC analysis showed that HbA1c at diagnosis and before delivery resulted a good predictor of adverse pregnancy outcome. CONCLUSIONS The present results indicate that HbA1c levels could be of help in predicting adverse pregnancy events.

Abstract
OBJECTIVE Since January 2008, obese women with type 2 diabetes were advised to gain 0-5 kg during pregnancy. The aim with this study was to evaluate fetal growth and perinatal morbidity in relation to gestational weight gain in these women. RESEARCH DESIGN AND METHODS A retrospective cohort comprised the records of 58 singleton pregnancies in obese women (BMI ≥30 kg/m(2)) with type 2 diabetes giving birth between 2008 and 2011. Birth weight was evaluated by SD z score to adjust for gestational age and sex. RESULTS Seventeen women (29%) gained ≤5 kg, and the remaining 41 gained >5 kg. The median (range) gestational weight gains were 3.7 kg (-4.7 to 5 kg) and 12.1 kg (5.5-25.5 kg), respectively. Prepregnancy BMI was 33.5 kg/m(2) (30-53 kg/m(2)) vs. 36.8 kg/m(2) (30-48 kg/m(2)), P = 0.037, and median HbA1c was 6.7% at first visit in both groups and decreased to 5.7 and 6.0%, P = 0.620, in late pregnancy, respectively. Gestational weight gain ≤5 kg was associated with lower birth weight z score (P = 0.008), lower rates of large-for-gestational-age (LGA) infants (12 vs. 39%, P = 0.041), delivery closer to term (268 vs. 262 days, P = 0.039), and less perinatal morbidity (35 vs. 71%, P = 0.024) compared with pregnancies with maternal weight gain >5 kg. CONCLUSIONS In this pilot study in obese women with type 2 diabetes, maternal gestational weight gain ≤5 kg was associated with a more proportionate birth weight and less perinatal morbidity.

Abstract
BACKGROUND Australian Aboriginal women have a high prevalence of type 2 diabetes (T2DM) in pregnancy and gestational diabetes (GDM). AIMS To review how screening practice affects the pregnancy data of all Indigenous women and their newborns living in Cape York, Queensland. METHODS All medical charts of mothers and their neonates delivered in the regional hospital over two-one-year periods (2006 and 2008) were reviewed. Universal testing with an oral glucose tolerance test (OGTT) was introduced in 2007. RESULTS Gestational diabetes (GDM) increased from 4.7 to 14.2%, and T2DM was similar (2.4 and 2.3%). There were 127 deliveries in 2006 and 134 in 2008. Testing rates with OGTT improved from 31.4% in 2006 to 65.6% in 2008. Mothers with diabetes in pregnancy (DIP) were older and heavier than non-DIP mothers. Caesarean section rates were significantly higher in the DIP group compared with the non-DIP group (66 vs 25%) in both time periods. The booking weight of DIP mothers decreased 16 kg, their babies normalised their weight, length and head circumference; respiratory distress and Apgar scores improved comparing the two periods. In DIP, infants >40% had hypoglycaemia; however, rates of serious complications were low. Rates of breastfeeding were similar between groups. Follow-up rates for GDM improved from 16.6% in 2006 to 31.6% in 2008. Of those tested one-third were diagnosed with T2DM. CONCLUSION The rate of GDM tripled after implementation of universal testing. Outcomes improved. There is still need for improvement in testing and follow-up practices in relation to DIP.

Abstract
Adolescence is a critical period for girls with type 1 diabetes mellitus (T1D). Reproductive issues, such as menstrual abnormalities, risk of an unplanned pregnancy, and contraception, should be addressed during this phase of life. This paper reviews several reproductive issues that are important in the care of adolescents, including pubertal development, menstrual abnormalities, ovulatory function, reproductive problems, the effects of hyperglycemia, contraception, and treatment of an unplanned pregnancy. A review of the literature was conducted. A MEDLINE search January 1966 to March 2011 was performed using the following MESH terms: puberty, menarche, ovary, polycystic ovary syndrome, menstruation, contraception, contraception-barrier, contraceptives-oral-hormonal, sex education, family planning services, and pregnancy in adolescence. This literature search was cross-referenced with an additional search on diabetes mellitus-type 1, diabetes complications, and pregnancy in diabetes. All published studies were searched regardless of the language of origin. Bibliographies were reviewed to extract additional relevant sources.

Abstract
Poorly controlled diabetes before conception and during pregnancy among women with pre-existing diabetes can cause major birth defects and spontaneous abortions, as wells as abnormal fetal growth and development including an offspring who is small or large for gestational age, or predisposed to obesity, type 2 diabetes, and metabolic syndrome in his/her lifetime. Conversely, for a woman with pre-existing diabetes, optimizing blood glucose levels before and during early pregnancy can reduce these risks dramatically. As insulin pump technology has evolved, continuous subcutaneous insulin infusion has become a safe and reliable method for treating diabetes during pregnancy. Although pump therapy is often preferred by patients and some experts, insulin pumps have not yet been shown to be superior to multiple daily injections of insulin during pregnancy. In this review of the literature we focus on the use of insulin pumps in the management of diabetes in pregnancy.

Abstract
Birth defects are the leading cause of infant mortality in the United States, which has one of the highest infant mortality rates in the developed world. Many of these birth defects can be attributed to pre-existing, or pregestational, diabetes in pregnancy, which significantly increases a mother's risk of having a child with a major birth defect. Strict preconceptional and early pregnancy glucose control, supplementation with multivitamins and fatty acids, and lower glycemic dietary management have been shown to reduce the incidence of birth defects in experimental and epidemiologic studies. However, because more than half of pregnancies are unplanned, these methods are not generalizable across the population. Thus, better interventions are urgently needed. Based on what we know about the molecular pathophysiology of diabetic embryopathy, our laboratory and others are developing interventions against to key molecular targets in this multifactorial disease process.

Abstract
BACKGROUND
The treatment of diabetes in pregnancy has potentially far-reaching benefits for both pregnant women with diabetes and their children and may provide a cost-effective approach to the prevention of obesity, type 2 diabetes mellitus, and metabolic syndrome. Early and accurate diagnosis of diabetes in pregnancy is necessary for optimizing maternal and fetal outcomes.
CONTENT
Optimal control of diabetes in pregnancy requires achieving normoglycemia at all stages of a woman's pregnancy, including preconception and the postpartum period. In this review we focus on new universal guidelines for the screening and diagnosis of diabetes in pregnancy, including the 75-g oral glucose tolerance test, as well as the controversy surrounding the guidelines. We review the best diagnostic and treatment strategies for the pregestational and intrapartum periods, labor and delivery, and the postpartum period, and discuss management algorithms as well as the safety and efficacy of diabetic medications for use in pregnancy.
SUMMARY
Global guidelines for screening, diagnosis, and classification have been established, and offer the potential to stop the cycle of diabetes and obesity caused by hyperglycemia in pregnancy. Normoglycemia is the goal in all aspects of pregnancy and offers the benefits of decreased short-term and long-term complications of diabetes.
