Non-efficacy of early intervention strategy for non-obese patients with early-onset gestational diabetes mellitus: solely based on the short-term outcomes.

INTRODUCTION: To verify the effectiveness of intervention in early pregnancy for women with early-onset gestational diabetes mellitus (GDM). RESEARCH DESIGN AND METHODS: This study included women with a singleton pregnancy who were diagnosed with early-onset GDM by 20 weeks of gestation according to the International Association of Diabetes and Pregnancy Study Group (IADPSG) threshold. We retrospectively evaluated the pregnancy outcomes in pregnant women with early-onset GDM. In the treatment from early pregnancy group (n=286), patients were diagnosed with early-onset GDM at the Yokohama City University Medical Center (YCU-MC) in 2015-2017 and were treated for GDM from early pregnancy. Concerning the treatment from mid-pregnancy group (n=248), participants were diagnosed with early-onset GDM at five sites, including the YCU-MC in 2018-2019, and were followed up without treatment until the second 75 g oral glucose tolerance test (OGTT) at 24-28 weeks of gestation. Treatment for GDM was given only if the GDM pattern was still present in the second OGTT. RESULTS: There were no significant differences in maternal backgrounds, including GDM risk factors and gestational weight gain, between the groups. Among the treatment from mid-pregnancy group, the false-positive early GDM was 124/248 (50%). Regarding pregnancy outcome, the rate of large for gestational age (LGA) was 8.8% in the treatment from early pregnancy group and 10% in the treatment from mid-pregnancy group, with no significant difference, whereas small for gestational age (SGA) was significantly higher in the treatment from early pregnancy group (9.4%) than in the treatment from mid-pregnancy group (4.8%) (p=0.046). There were no significant differences in maternal adverse events and neonatal outcomes between the groups. In a subanalysis limited to body mass index >25 kg/m2, LGA was significantly lower in the treatment from early pregnancy group than in the treatment from mid-pregnancy group. CONCLUSIONS: The strategy for diagnosing GDM by IADPSG thresholds in early pregnancy and providing treatment to all patients from early pregnancy did not improve the pregnancy outcomes, but rather increased the SGA rate.

High probability of false-positive gestational diabetes mellitus diagnosis during early pregnancy.

INTRODUCTION: This study aimed to assess the validity of applying the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria for the diagnosis of gestational diabetes mellitus (GDM) at any time during pregnancy. RESEARCH DESIGN AND METHODS: This multicenter cohort study was conducted at five Japanese facilities from January 2018 to April 2019. The study cohort included women at a high risk of GDM who met one or more of the following IADPSG criteria during early pregnancy: fasting plasma glucose (FPG) ≥92 mg/dL and 75 g oral glucose tolerance test (OGTT) value of ≥180 mg/dL at 1 hour, or ≥153 mg/dL at 2 hour (hereafter early-onset GDM). Women diagnosed with early-onset GDM were followed up without therapeutic intervention and underwent the 75 g OGTT again during 24-28 weeks of gestation. Those exhibiting the GDM patterns on the second 75 g OGTT were diagnosed with true GDM and treated, whereas those exhibiting the normal patterns were diagnosed with false positive early GDM and received no therapeutic intervention. RESULTS: Of the 146 women diagnosed with early-onset GDM, 69 (47%) had normal 75 g OGTT values at 24-28 weeks of gestation, indicating a false-positive result. FPG levels were significantly higher in the first 75 g-OGTT test than in the second 75 g-OGTT test (93 mg/dL and 87.5 mg/dL, respectively; p<0.001). FPG levels were high in 86 (59%) women with early-onset GDM during early pregnancy but in only 39 (27%) women during mid-pregnancy. Compared with false positive early GDM, true GDM was more frequently associated with adverse pregnancy outcomes. CONCLUSIONS: Although women with early-onset GDM were followed up without treatment, the results of repeated 75 g OGTT during mid-pregnancy were normal in about 50%. Our data did not support the adoption of IADPSG thresholds for the diagnosis of GDM prior to 20 weeks of gestation.

Seizures associated with Lupus during pregnancy.

A sudden flare of previously stable SLE may give rise to CNS lupus. During pregnancy, seizures associated with CNS lupus can cause hypoxic-ischemic encephalopathy (HIE) in the infant.

Pregnancy outcomes of women with coexisting systemic lupus erythematosus flare and preeclampsia.

OBJECTIVES: Systemic lupus erythematosus (SLE) flare and preeclampsia are difficult to differentiate from each other and occasionally coexist; This study aimed to analyze cases requiring termination of pregnancy due to SLE flare or preeclampsia and to elucidate the association between these two conditions; Methods. Out of 71 pregnancies in 60 women managed for SLE-complicated pregnancies who delivered at or after 22 weeks' gestation at a tertiary center, 7 pregnancies were terminated due to uncontrollable severe SLE flare or severe preeclampsia We retrospectively analyzed the clinical courses and laboratory findings of these 7 cases to determine whether their pathological conditions were attributable to SLE flare alone, preeclampsia alone, or the coexistence of these two conditions. RESULTS: One of the 7 cases had preeclampsia alone, two had SLE alone, and four had both conditions. The coexistence of preeclampsia and SLE was thus the most common condition. In cases with both conditions, SLE flare had preceded preeclampsia, thereby making treatment after delivery difficult. CONCLUSION: Severe SLE flare often preceded severe preeclampsia and worsened after delivery. When differentiating severe SLE flare from severe preeclampsia is difficult during pregnancy, women should be regarded as having SLE flare rather than preeclampsia and aggressively treated.

Adverse pregnancy outcomes associated with adenomyosis with uterine enlargement.

AIM: The aim of this study was to elucidate the risk of poor pregnancy outcomes in women with adenomyosis by comparing their outcomes to those of women without uterine abnormalities. MATERIAL AND METHODS: The subjects were 36 women diagnosed with adenomyosis before pregnancy who were managed at a tertiary care center between January 2002 and December 2012. Our hospital database was retrospectively reviewed to identify pregnancy outcomes associated with adenomyosis. The control group consisted of 144 women without uterine abnormalities who gave birth during the same period and whose age at delivery was adjusted by applying propensity scores. Pregnancy outcomes were compared between the adenomyosis and control groups. The main outcomes were gestational age at delivery, preterm delivery, preterm premature rupture of membranes, fetal malpresentation, cesarean delivery, small-for-gestational age, 5-min Apgar score < 7, umbilical arterial pH < 7.1, and neonatal intensive care unit admission. The data are presented as medians (range) or frequencies (percentage). RESULTS: The adenomyosis group had significantly higher rates of preterm delivery (41.7% vs 12.5%), preterm premature rupture of membranes (19.4% vs 4.2%), small-for-gestational age (33.3% vs 10.4%), fetal malpresentation (27.8% vs 8.3%), and cesarean delivery (58.3% vs 24.3%), as compared with the control group. No significant differences were observed in 5-min Apgar score < 7 or umbilical arterial pH < 7.1 between the two groups. CONCLUSIONS: Pregnancies in women with adenomyosis were associated with a higher preterm delivery rate and more frequent occurrences of fetal growth restriction and fetal malpresentation, such that both pregnancy and delivery outcomes were poor.

Significance of cervical ripening in pre-induction treatment for premature rupture of membranes at term.

AIM: This study aimed to determine whether mechanical cervical dilatation with a laminaria tent in women with premature rupture of membranes (PROM) at term may influence the maternal/neonatal outcomes. METHODS: We reviewed the medical records and histopathologic results of the placenta in 782 women with PROM at term. Of the 486 women seen prior to 2010 (group 1), 85 had Bishop scores of 5 or less and underwent insertion of laminaria tents (group A). In the 296 women admitted after 2010 (group 2), 27 had Bishop scores of 5 or less and underwent labor management without insertion of laminaria tents (group B). The patient characteristics, delivery course and neonatal outcomes were compared between the groups. RESULTS: There were no significant differences in the maternal age, percentage of nulliparas, body mass index, gestational age at delivery or Bishop score between the groups. The Bishop score improved from 2.5 to 6.1 after laminaria tent insertion in group A. However, there were no significant intergroup differences in the frequency of use of labor-inducing agents or the time interval from PROM to delivery. The incidence of clinical/pathological chorioamnionitis was not higher in group A than in group B. No significant differences were found in the Apgar scores, umbilical artery pH or frequency of asphyxia neonatorum between the groups. Mechanical cervical dilatation by laminaria tent insertion neither increased the incidence of infection nor contributed to improvement of the perinatal prognosis. CONCLUSION: Mechanical cervical dilatation does not provide any benefit for women with PROM at term.
