Left and right ventricular filling was studied prospectively in 50 full-term (39.4 +/- 1.3 wk) asymptomatic newborns of mothers with gestational diabetes mellitus (GDM). Their data were compared with those of 80 asymptomatic full-term (39.8 +/- 1.2 wk) infants who served as control subjects. Infants were examined in the immediate newborn period (less than 48 h) and then again at 2-4 and 6-9 wk. Although mean weight, length, and gestational age did not differ, the mean +/- SD left ventricular dimensions during diastole (1.73 +/- 0.15 vs. 1.81 +/- 0.18 cm, P = 0.007) and systole (1.22 +/- 0.15 vs. 1.31 +/- 0.17 cm, P = 0.004) were significantly lower in infants of mothers with GDM compared with control infants. Diastolic measurements suggested a shift from the early diastolic filling of the ventricle to the later period of atrial systole in infants of mothers with GDM. A lower initial one-third area fraction and a higher peak flow velocity and velocity time integral during atrial systole were noted at the mitral valve in infants of mothers with GDM. These changes had resolved by 2-4 wk of age. The altered diastolic filling patterns in infants of mothers with GDM indicate poor myocardial relaxation and/or decreased passive compliance of the ventricular myocardium. These alterations were observed in asymptomatic infants in the absence of left ventricular or septal hypertrophy. If exposed to significant stress such as asphyxia or sepsis, the observed myocardial dysfunction could lead to higher morbidity in these infants.

Diabetes in pregnant Mexican-American women is a serious and expensive health problem. At the University of California, San Diego Medical Center, 44% of pregnant women are Mexican American. In the Diabetes in Pregnancy Clinic, only 7% of women with insulin-dependent diabetes are in this ethnic group compared with 66% of non-insulin-dependent diabetic patients and 51% of those with gestational diabetes mellitus (GDM). GDM is the most common complication of pregnancy in Mexican Americans with a prevalence approximately three times higher than that of whites (4.5 vs. 1.5%). Mexican-American obese GDM subjects had more frequent cesarean sections and were more likely to have complications of premature rupture of membranes and preterm labor (NS). Polycythemia and sepsis also occurred more often in their infants. Anthropometric measurements in infants of both lean and obese GDM subjects differed from those of infants of mothers without GDM. Infants of lean mothers with GDM were heavier and longer than those of lean mothers without GDM. In addition, they had increased waist-hip ratio and triceps and subscapular skin folds. Infants of obese mothers with GDM were heavier than those of lean mothers with GDM. Moreover, they were longer (P less than 0.04); had a higher body mass index (P less than 0.04); and larger waist and hip circumferences (P less than 0.03) and buccal (P less than 0.01), subscapular (P less than 0.01), and sum of skin-fold measurements (P less than 0.03). Our observations indicate that pregnant diabetic Mexican-American women have predominantly GDM and non-insulin-dependent diabetes. They represent a major public health problem because of increased maternal and neonatal morbidity.

The rate of retrolental fibroplasia in relation to prenatal and neonatal characteristics was explored on the basis of a cohort of 3,025 neonates with birth weight less than 1,750 g. The overall rate of retrolental fibroplasia of any degree at hospital discharge was 11%, varying from 43% for those with birth weight between 500 and 749 g to 3% for those in the 1,500- to 1,750-g category. Among the potential determinants, the main interest was in nonhyperoxic characteristics, conditional on measures of prematurity and oxygen supplementation. Maternal diabetes and antihistamine use during the last 2 weeks of pregnancy were associated with significantly higher rates of retrolental fibroplasia, whereas toxemia was associated with lower rates. Frequent apneic spells, bronchopulmonary dysplasia, and sepsis in the neonate were also associated with significantly higher rates. On the other hand, the data indicate no independent role of low Apgar score, intraventricular hemorrhage, exchange transfusion, patent ductus arteriosus, or certain other characteristics previously postulated as risk factors.

The leukocyte glycoprotein L-selectin mediates an early step in the recruitment of leukocytes to sites of inflammation. L-Selectin surface expression is rapidly down-regulated by inflammatory signals in vitro. In a prospective study, we found L-selectin expression on umbilical cord blood granulocytes and monocytes to be significantly decreased in newborn infants with acute bacterial infection compared with controls (p < 0.01). A significantly reduced L-selectin expression of both granulocytes and monocytes was also found to be associated with an increased neutrophil immature/total ratio (p < 0.01) but not with other laboratory markers of neonatal sepsis. There was no apparent impact of prematurity, low birth weight, gestational hypertension, or gestational diabetes on L-selectin expression. Although the mode of delivery did not affect granulocyte L-selectin expression, umbilical cord blood monocytes showed an increased L-selectin expression after emergency cesarean delivery compared with samples obtained after elective cesarean or vaginal delivery (p < 0.01). We conclude that acute systemic inflammation results in down-regulation of granulocyte and monocyte L-selectin expression in vivo similar to that observed in vitro.

We describe six pregnancies in five patients with Cushing's disease --four had undergone transsphenoidal surgery, with improvement but no cure of their hypercortisolism; the other woman became pregnant during initial work up. At conception, none of the patients were receiving specific treatment for hypercortisolism. Mean free urinary cortisol (FUC) prior to pregnancy was 430 nmol/24 h (normal range: 51-280). In two patients, FUC throughout pregnancy increased significantly, but no clinical progression was observed. FUC measured in 20 healthy pregnant women was found to rise above the normal non-pregnant range ( < 280 nmol/24 h) in the second (mean +/- 2 S.D. = 463 +/- 256 nmol/24 h; P < 0.01) and third trimester (424 +/- 210 nmol/24 h; P < 0.05). However, in the Cushing patients values were higher. Two pregnancies ended in spontaneous abortions, one resulted in an ectopic pregnancy, and the remaining three were followed to term of which one developed third trimester gestational diabetes, and her baby developed neonatal sepsis which resolved uneventfully. We conclude that despite high abortion and ectopic pregnancy rates, a remarkably uneventful and uncomplicated outcome with no clinical progression of cushingoid symptoms, was observed in two of the three pregnancies followed to term, despite significant increases in FUC.

Preterm labor, cervical cerclage (especially when performed as an emergency procedure), and diabetes mellitus are all associated with an increased risk of chorioamnionitis. It might be expected that the combination of all 3 could lead to especially severe infection. We report such a case. A woman with a history of two spontaneous midtrimester abortions had had cervical cerclage performed at 13 weeks. She was referred at 24 weeks' gestation with preterm labor, and the cervix was found to be dilated. An emergency repeat cerclage was performed. The following day, ultrasonography revealed the presence of intra-amniotic gas. Infection was confirmed by the presence of a purulent cervical discharge, a neutrophilia with a left shift, and an elevated C-reactive protein level. The cervical stitch was removed and labor induced. The infant was liveborn, but succumbed to the complications of prematurity and sepsis. E. coli was isolated. In her subsequent pregnancy, severe gestational diabetes was diagnosed and following pregnancy, permanent diabetes mellitus was confirmed. The combination of infection, diabetes, and intact membranes may lead to a particularly severe form of chorioamnionitis, with the production of gas within the amniotic cavity. Infection should be excluded before emergency cervical cerclage, especially in the woman with diabetes mellitus.

We evaluated the reliability of serum concentrations of procalcitonin for the diagnosis of early- and late-onset sepsis in a neonatal intensive care unit (NICU) setting. Timed procalcitonin determinations were prospectively obtained during two postnatal periods: 0-48 hours of age (period 1) and 3-30 days of age (period 2). In period 1, we measured procalcitonin concentrations in 83 healthy newborns (group 0) and in 120 NICU patients (14 with culture-proven sepsis, group 1A; 14 with clinical septicemia, group 1B; 75 with no evidence of infection, group 2; and 17 with uncertain findings, group 3). After we established 95% hour-specific reference ranges for group 0, we performed multiple linear regression analyses to determine which maternal, intrapartum, and neonatal complications would affect normal procalcitonin values. Maternal diabetes was the only variable identified in group 2 patients that induced a significant deviation from procalcitonin reference ranges. Analyses of the pooled procalcitonin values obtained for group 1 patients over the 48-hour period after birth yielded a sensitivity of 92.6% and a specificity of 97.5% for procalcitonin concentrations in the detection of early-onset sepsis. In period 2, blood samples from 23 cases with systemic infections were analyzed for procalcitonin concentrations at the onset of signs of infection. The control group was formed by matching four uninfected NICU patients to each infected case. None of the procalcitonin values for the 92 controls overlapped those for the cases (sensitivity and specificity, 100%). Procalcitonin is a promising marker for the diagnosis of early- and late-onset sepsis in neonates at high risk for this infection.

The aim of this study is to explore the relationship between high cord blood thyroid-stimulating hormone (TSH) level and in-utero stress to the fetus in gestational diabetes mellitus (GDM). Cord blood TSH results were analyzed in 1,578 euthyroid infants from singleton pregnancies with GDM: 103 with elevated TSH (>16 mIU/l) and 1,475 with normal TSH. Maternal characteristics, pregnancy outcome and perinatal complications were compared between the two groups. Multiple logistic regression was used to study the association between high cord blood TSH level and various perinatal complications which reflect in-utero stress in GDM after adjusting for the confounding effects of parity, instrumental delivery, cesarean section and baby gender. High cord blood TSH level was found to be associated with the 1-min Apgar score <7 (OR 3.31, 95% CI 1.78-6.16), birth trauma (OR 3.44, 95% CI 1.11-10.69), neonatal jaundice requiring treatment (OR 2.08, 95% CI 1.30-3.32), neonatal sepsis (OR 2.34, 95% CI 1.24-4.42), respiratory complications (OR 3.45, 95% CI 1.37-8.70), neurological complications (OR 8.01, 95% CI 1.91-33.60) and overall perinatal morbidity (OR 2.41, 95% CI 1.58-3.67). Cord blood TSH level seems to be a better and independent indicator of the in-utero stress to the fetus in GDM when compared to the commonly used sugar profile result and HbA1c level.
