RESUMO

Objective: It was to explore the ultrasonic characteristics of complications of twin pregnancies with monochorionic diamniotic (MCDA) during various pregnancy periods and the differences in pregnancy outcomes. Methods: One hundred pregnant women with MCDA were included in the study. They were rolled into a complication group (44 cases) and a non-complication group (56 cases) according to whether they had complications. The pulsatility index (PI), resistance index (RI), and systolic/diastolic (S/D) values of ultrasound in pregnant women and the final neonatal situation at each time period were compared and analyzed. Results: In pregnant women with twin-twin transfusion syndrome (TTTS), there was no significant difference in RI and S/D values between the larger and smaller twin during pregnancy (P > .05). Compared to the group without complications, the incidence of neonatal death was significantly increased in the complication group, and the newborn's weight, length, head circumference, and Apgar score were significantly lower (P < .05). In pregnant women with selective intrauterine growth restriction (sIUGR), the RI and PI values of the larger twin were significantly higher than those of the smaller twin during pregnancy, and S/D values were significantly lower (P < .05). The newborns in the group without complications had significantly higher body weight, length, and head circumference (P < .05). In pregnant women with gestational diabetes mellitus (GDM), there was no significant difference in RI and S/D values between the larger and smaller twin during pregnancy (P > .05), and there were no significant differences in other indicators compared to the group without complications. In pregnant women with premature rupture of membrane (PROM), there was no significant difference in RI and S/D values between the larger and smaller twin during pregnancy (P > .05), but the newborns in the group without complications had significantly higher weight, length, Apgar score, and lower incidence of neonatal death (P < .05). In pregnant women with preeclampsia (PE), there was no significant difference in RI and S/D values between the larger and smaller twin during pregnancy (P > .05), and there were no significant differences in other indicators compared to the group without complications (P > .05). Conclusion: Pregnant women with sIUGR had significantly higher RI and PI values in the larger twin and significantly lower S/D values compared to the smaller twin during pregnancy, while no significant differences were observed for other complications. The combination of TTTS and PROM decreased the birth weight, body length, head circumference, and Apgar score of twins and increased the mortality rate.

RESUMO

Brain injury due to intrauterine growth restriction (IUGR) is a thorny clinical problem that often leads to permanent neurological deficits such as cerebral palsy. Few practical therapies can treat an IUGR-associated brain injury. We employed acupuncture to treat a 6-month-old male patient with severe hypoxic-ischemic encephalopathy (HIE) due to IUGR, as confirmed by magnetic resonance imaging (MRI). Three courses of acupuncture treatment significantly improved some of the patient's clinical characteristics, such as his insensitive responsiveness and motor deficits, with remarkably reversed HIE features on MRI at 1-year of age. This case suggests that acupuncture is a potential treatment option for an IUGR-associated brain injury and warrants further investigation.

RESUMO

To date there is no effective treatment for pregnancies complicated by fetal growth restriction (FGR). Salvia miltiorrhiza, a traditional Chinese herb has been shown to promote blood flow and improve microcirculatory disturbance. In this pilot study, we evaluated whether S. miltiorrhiza can potentially become a possible therapy for FGR. Nineteen pregnant women with FGR were treated with S. miltiorrhiza and ATP supplementation for an average of 7 days, and 17 cases received ATP supplementation as controls. The estimated fetal weights (EFWs) were measured by ultrasound after treatment, and the birthweights were recorded after birth. After treatment with S. miltiorrhiza, 7 (37%) FGR cases showed an increase in EFW to above the 10th percentile, compared with 4 (23%) FGR cases in controls (odds ratio: 1.896, 95% confidence limits (CLs): 0.44-8.144). At delivery, 10 (53%) FGR cases in the treatment group delivered babies with a birthweight above the 10th percentile, compared with 6 (35%) FGR cases in the control group (odds ratio: 2.037, 95% CL: 0.532-7.793); 80 or 64% FGR cases in the treatment group showed an increase in fetal abdominal circumference (AC) or biparietal diameter (BPD) above the 10th percentile before delivery. While 44 or 30% FGR cases in the control group showed an increase in AC or BPD. No improvement of head circumference (HC) or femur length (FL) was seen. These pilot data suggest the need for multicenter randomized clinical trials on the potential of S. miltiorrhiza to improve perinatal outcome in pregnant women complicated by FGR.

RESUMO

OBJECTIVES: To investigate the effectiveness of routine ultrasonography in the third trimester in reducing adverse perinatal outcomes in low risk pregnancies compared with usual care and the effect of this policy on maternal outcomes and obstetric interventions. DESIGN: Pragmatic, multicentre, stepped wedge cluster randomised trial. SETTING: 60 midwifery practices in the Netherlands. PARTICIPANTS: 13 046 women aged 16 years or older with a low risk singleton pregnancy. INTERVENTIONS: 60 midwifery practices offered usual care (serial fundal height measurements with clinically indicated ultrasonography). After 3, 7, and 10 months, a third of the practices were randomised to the intervention strategy. As well as receiving usual care, women in the intervention strategy were offered two routine biometry scans at 28-30 and 34-36 weeks' gestation. The same multidisciplinary protocol for detecting and managing fetal growth restriction was used in both strategies. MAIN OUTCOME MEASURES: The primary outcome measure was a composite of severe adverse perinatal outcomes: perinatal death, Apgar score <4, impaired consciousness, asphyxia, seizures, assisted ventilation, septicaemia, meningitis, bronchopulmonary dysplasia, intraventricular haemorrhage, periventricular leucomalacia, or necrotising enterocolitis. Secondary outcomes were two composite measures of severe maternal morbidity, and spontaneous labour and birth. RESULTS: Between 1 February 2015 and 29 February 2016, 60 midwifery practices enrolled 13 520 women in mid-pregnancy (mean 22.8 (SD 2.4) weeks' gestation). 13 046 women (intervention n=7067, usual care n=5979) with data based on the national Dutch perinatal registry or hospital records were included in the analyses. Small for gestational age at birth was significantly more often detected in the intervention group than in the usual care group (179 of 556 (32%) v 78 of 407 (19%), P<0.001). The incidence of severe adverse perinatal outcomes was 1.7% (n=118) for the intervention strategy and 1.8% (n=106) for usual care. After adjustment for confounders, the difference between the groups was not significant (odds ratio 0.88, 95% confidence interval 0.70 to 1.20). The intervention strategy showed a higher incidence of induction of labour (1.16, 1.04 to 1.30) and a lower incidence of augmentation of labour (0.78, 0.71 to 0.85). Maternal outcomes and other obstetric interventions did not differ between the strategies. CONCLUSION: In low risk pregnancies, routine ultrasonography in the third trimester along with clinically indicated ultrasonography was associated with higher antenatal detection of small for gestational age fetuses but not with a reduced incidence of severe adverse perinatal outcomes compared with usual care alone. The findings do not support routine ultrasonography in the third trimester for low risk pregnancies. TRIAL REGISTRATION: Netherlands Trial Register NTR4367.

RESUMO

BACKGROUND: Preterm infants are at risk for neurodevelopmental impairment. Intrauterine growth restriction (IUGR) further increases this risk. Brain imaging studies are often utilized at or near term-equivalent age to determine later prognosis. OBJECTIVE: To evaluate the association between intrauterine growth and regional brain volume on MRI scans performed in preterm infants at or near term-equivalent age. METHODS: This is a retrospective case-control study of 24 infants born at gestational age ≤30 weeks and cared for in a large, inner-city, academic neonatal intensive-care unit from 2012 to 2013. Each IUGR infant was matched with 1-2 appropriate for gestational age (AGA) infants who served as controls. Predischarge MRI scans routinely obtained at ≥36 weeks' adjusted age were analyzed for regional brain volumetric differences. We examined the association between IUGR and thalamic, basal ganglion, and cerebellar brain volumes in these preterm infants. RESULTS: Compared to AGA infants, IUGR infants had a smaller thalamus (7.88 vs. 5.87 mL, p = 0.001) and basal ganglion (8.87 vs. 6.92 mL, p = 0.002) volumes. There was no difference in cerebellar volumes between the two study groups. Linear regression analyses revealed similar trends in the associations between IUGR and brain volumes after adjusting for sex, gestational age at birth, and postconceptual age and weight at MRI. CONCLUSIONS: Thalamus and basal ganglion volumes are reduced in growth-restricted preterm infants. These differences may preferentially impact neurodevelopmental outcomes. Further research is needed to explore these relationships.

RESUMO

BACKGROUND: Intrauterine growth restriction and premature birth represent 2 independent problems that may occur simultaneously and contribute to impaired neurodevelopment. OBJECTIVE: The objective of the study was to assess changes in the frontal lobe metabolic profiles of 1 year old intrauterine growth restriction infants born prematurely and adequate-for-gestational-age controls, both premature and term adequate for gestational age and their association with brain structural and biophysical parameters and neurodevelopmental outcome at 2 years. STUDY DESIGN: A total of 26 prematurely born intrauterine growth restriction infants (birthweight <10th centile for gestational age), 22 prematurely born but adequate for gestational age controls, and 26 term adequate-for-gestational-age infants underwent brain magnetic resonance imaging and magnetic resonance spectroscopy at 1 year of age during natural sleep, on a 3 Tesla scanner. All brain T1-weighted and diffusion-weighted images were acquired along with short echo time single-voxel proton spectra from the frontal lobe. Magnetic resonance imaging/magnetic resonance spectroscopy data were processed to derive structural, biophysical, and metabolic information, respectively. Neurodevelopment was evaluated at 2 years of age using the Bayley Scales 3rd edition, assessing cognitive, language, motor, socioemotional, and adaptive behavior. RESULTS: Prematurely born intrauterine growth restriction infants had slightly smaller brain volumes and increased frontal lobe white matter mean diffusivity compared with both prematurely born but adequate for gestational age and term adequate for gestational age controls. Frontal lobe N-acetylaspartate levels were significantly lower in prematurely born intrauterine growth restriction than in prematurely born but adequate for gestational age infants but increased in prematurely born but adequate for gestational age compared with term adequate-for-gestational-age infants. The prematurely born intrauterine growth restriction group also showed slightly lower choline compounds, borderline decrements of estimated glutathione levels, and increased myoinositol to choline ratios, compared with prematurely born but adequate for gestational age controls. These specific metabolite changes were locally correlated to lower gray matter content and increased mean diffusivity and reduced white matter fraction and fractional anisotropy. Prematurely born intrauterine growth restriction infants also showed a tendency for poorer neurodevelopmental outcome at 2 years, associated with lower levels of frontal lobe N-acetylaspartate at 1 year within the preterm subset. CONCLUSIONS: Preterm intrauterine growth restriction infants showed altered brain metabolite profiles during a critical stage of brain maturation, which correlate with brain structural and biophysical parameters and neurodevelopmental outcome. Our results suggest altered neurodevelopmental trajectories in preterm intrauterine growth restriction and adequate-for-gestational-age infants, compared with term adequate-for-gestational-age infants, which require further characterization.

RESUMO

BACKGROUND: Small for gestational age (SGA) is a global health problem. Identifying the timing of fetal growth faltering is critical for developing preventive interventions. We aim to describe patterns of fetal growth and to predict SGA at birth using fetal ultrasound measurements. METHODS: We studied 1412 pregnant women enrolled in a randomised-controlled trial evaluating maternal micronutrient supplementation in Thai Nguyen province, Vietnam. Ultrasound examinations included biparietal diameter (BPD), head circumference (HC) and abdominal circumference (AC), and femur length (FL). Measures were assessed using the new international fetal growth standards (INTERGROWTH-21st Project). Generalised linear mixed logit regression models were used to examine the association between ultrasound measures and SGA at birth. RESULTS: Overall fetal growth restriction began in early pregnancy and continued through delivery, but the timing of growth faltering varied by measure: it began by 20 weeks for HC, BPD and AC, earlier as compared to FL growth that started >30 weeks. SGA infants had significantly lower mean fetal growth parameters as early as 14 weeks. Ultrasound measures below the 10th percentile were associated with a two to four times higher risk of SGA at birth compared to fetuses greater than the 50th percentile, with the largest odds ratios for AC (OR 3.9, 95% confidence interval (CI) 2.7, 5.7). CONCLUSIONS: Fetal growth faltering by ultrasound begins in early gestation among rural Vietnamese populations; these patterns clearly identified those to be born SGA. Efforts to prevent fetal growth faltering must begin early in pregnancy and perhaps even before pregnancy.

RESUMO

AIM: The relation between biophysical profile (BPP), cerebroplacental (C/P) ratio, and lecithin/sphingomyelin (L/S) ratio as a predictor perinatal outcome in term intrauterine growth restricted (IUGR) neonates was evaluated. MATERIALS AND METHODS: A retrospective study of the perinatal outcome of 77 term monofetal pregnancies complicated with IUGR fetuses (< 10 percentile) who were terminated by cesarean section in 2010 was performed at the Institute of Gynecology and Obstetrics, Belgrade. RESULTS: The most frequent early neonatal complication was asphyxia. The authors found a strong correlation between the L/S ratio and birth weight (BW) r = 0.609, as well as between BPP and Apgar score 5 r = 0.583. Significant negative correlation was found between asphyxia and BPP r = -0.398, as well as between asphyxia and C/P ratio r = -0.379. CONCLUSION: In serous IUGR neonates, low values of BPP and L/S ratios predicted asphyxia.

RESUMO

CONTEXT: Adverse environmental exposures lead to developmental adaptations in fetal life. The influences of maternal physical characteristics and lifestyle habits on first-trimester fetal adaptations and the postnatal consequences are not known. OBJECTIVE: To determine the risk factors and outcomes associated with first-trimester growth restriction. DESIGN, SETTING, AND PARTICIPANTS: Prospective evaluation of the associations of maternal physical characteristics and lifestyle habits with first-trimester fetal crown to rump length in 1631 mothers with a known and reliable first day of their last menstrual period and a regular menstrual cycle. Subsequently, we assessed the associations of first-trimester fetal growth restriction with the risks of adverse birth outcomes and postnatal growth acceleration until the age of 2 years. The study was based in Rotterdam, The Netherlands. Mothers were enrolled between 2001 and 2005. MAIN OUTCOME MEASURES: First-trimester fetal growth was measured as fetal crown to rump length by ultrasound between the gestational age of 10 weeks 0 days and 13 weeks 6 days. Main birth outcomes were preterm birth (gestational age <37 weeks), low birth weight (<2500 g), and small size for gestational age (lowest fifth birth centile). Postnatal growth was measured until the age of 2 years. RESULTS: In the multivariate analysis, maternal age was positively associated with first-trimester fetal crown to rump length (difference per maternal year of age, 0.79 mm; 95% confidence interval [CI], 0.41 to 1.18 per standard deviation score increase). Higher diastolic blood pressure and higher hematocrit levels were associated with a shorter crown to rump length (differences, -0.40 mm; 95% CI, -0.74 to -0.06 and -0.52 mm; 95% CI, -0.90 to -0.14 per standard deviation increase, respectively). Compared with mothers who were nonsmokers and optimal users of folic acid supplements, those who both smoked and did not use folic acid supplements had shorter fetal crown to rump lengths (difference, -3.84 mm; 95% CI, -5.71 to -1.98). Compared with normal first-trimester fetal growth, first-trimester growth restriction was associated with increased risks of preterm birth (4.0% vs 7.2%; adjusted odds ratio [OR], 2.12; 95% CI, 1.24 to 3.61), low birth weight (3.5% vs 7.5%; adjusted OR, 2.42; 95% CI, 1.41 to 4.16), and small size for gestational age at birth (4.0% vs 10.6%; adjusted OR, 2.64; 95% CI, 1.64 to 4.25). Each standard deviation decrease in first-trimester fetal crown to rump length was associated with a postnatal growth acceleration until the age of 2 years (standard deviation score increase, 0.139 per 2 years; 95% CI, 0.097 to 0.181). CONCLUSIONS: Maternal physical characteristics and lifestyle habits were independently associated with early fetal growth. First-trimester fetal growth restriction was associated with an increased risk of adverse birth outcomes and growth acceleration in early childhood.

RESUMO

OBJECTIVE: Heparin was hypothesized to facilitate the growth of the growth-restricted fetus. Our study was to assess the efficiency of heparin in treating fetus with growth restriction and to explore the possible mechanisms. METHODS: Seventy-three pregnant women were selected in this study. Based on regular treatments, patients randomly received either heparin or dan-shen combined with low-molecular weight dextrose. A serial ultrasonography and hematological measurements were performed on each patient at the enrolment and 7 days after the first treatment. Neonatal birth weight, 1-min Apgar score and gestational age were recorded. Placentas were collected for apoptotic indices. RESULTS: Heparin significantly improved maternal hemorrheological indices, fetal growth velocities and neonatal outcomes. It also reduced apoptosis in trophoblasts. CONCLUSIONS: Our results provide evidence that heparin significantly improves the growth of the growth-restricted fetus. The growth improvement is probably achieved by the changes in maternal hemorrheology and the attenuated apoptosis in trophoblasts.

RESUMO

BACKGROUND & AIMS: Infants born with severe IUGR are exposed to higher neonatal mortality and morbidity rates, as compared with appropriate-for-gestational-age. They are exposed to a higher risk of developing chronic disease such as hypertension, coronary artery disease, obesity, and type 2 diabetes in adulthood. L-Arginine is a precursor of nitric oxide (NO) and may play a role in placental vascular mediation or local vasodilatation. OBJECTIVE: The current study was designed to determine whether oral supplementation of gravid patients suffering from severe intrauterine growth restriction (IUGR) with L-arginine, would enhance birth weight and/or decrease neonatal morbidity. PATIENTS AND METHODS: Forty-four patients with a singleton pregnancy who had been referred for IUGR detected by ultrasonic examination were included. Vascular IUGR was defined by fetal abdominal circumference less than or equal to the 3rd percentile, associated with abnormal uterine Doppler. After double-blind randomization, patients received either 14 g/day of L-arginine, or a placebo. RESULTS: The characteristics of the two groups of patients (IUGR with L-arginine vs IUGR with placebo) were similar upon randomization. There was no significant difference between the two groups concerning birth weight (1042+/-476 vs. 1068+/-452 g). At delivery, maternal and neonatal characteristics were similar in the two groups. There was no difference in the Clinical Risk Index for Babies (CRIB) score, the duration of ventilatory assistance, nor the delay between birth and full enteral feeding between the two groups. CONCLUSION: In this study which is, at the best of our knowledge, the first double-bind, multicenter, randomized trial in this condition, L-arginine is not an effective treatment for severe vascular growth restriction.

RESUMO

OBJECTIVES: To evaluate the feasibility and reproducibility of volume segmentation of fetal intracranial structures using three-dimensional (3D) ultrasound imaging, and to estimate differences in the volume of intracranial structures between intrauterine growth-restricted (IUGR) and appropriate-for-gestational age (AGA) fetuses. METHODS: Total intracranial, frontal, thalamic and cerebellar volumes were measured using 3D ultrasound imaging and Virtual Organ Computer-aided AnaLysis (VOCAL) in 39 IUGR and 39 AGA fetuses matched for gestational age, at 28-34 weeks of gestation. Volumes of, and ratios between, structures were estimated, and differences between IUGR and AGA fetuses were calculated. Volume measurements were performed by two observers, and interobserver and intraobserver intraclass correlation coefficients (ICCs) were calculated for each structure. RESULTS: Volumes were satisfactorily obtained in all fetuses. All net volumes except those for the thalamus (P = 0.23) were significantly smaller (P = 0.001) in IUGR fetuses. After adjusting volumes for biparietal diameter the frontal volume was significantly smaller (P = 0.02) and the thalamic volume significantly greater (P = 0.03) in IUGR fetuses than in AGA fetuses. Significant intergroup differences in the ratios between structures were found only in those involving the frontal region. Interobserver ICCs were as follows: total intracranial 0.97 (95% CI, 0.92-0.98), cerebellar 0.69 (95% CI, 0.44-0.75), frontal 0.66 (95% CI, 0.42-0.79) and thalamic 0.54 (95% CI, 0.37-0.72). CONCLUSIONS: IUGR fetuses show differences in the volume of intracranial structures compared with AGA fetuses, with the largest difference found in the frontal region. These differences might be explained by in-utero processes of neural reorganization induced by chronic hypoxia.

RESUMO

IMAGe association is a recently recognized multi-system disorder of unknown etiology. IMAGe is a mnemonic acronym that stands for Intrauterine growth retardation, Metaphyseal dysplasia, Adrenal hypoplasia congenita, and Genital anomalies (OMIM 300290). Suspicion for the disorder is readily raised by the distinctive clinical and endocrinological constellation, and radiological identification of metaphyseal dysplasia is crucial for the diagnosis. However, knowledge of the onset, evolution, severity, and variation of the metaphyseal dysplasia is currently limited. We illustrate the radiological evolution of an affected girl from her premature birth to early childhood. Her initial skeletal changes included thin ribs, delayed ossification of the juxtatruncal bones, and delayed epiphyseal ossification. The former two became less conspicuous during infancy. Metaphyseal dysplasia was not discerned at birth. However, mild metaphyseal cupping, sclerosis and longitudinal striations became manifest in late infancy, and then progressed with age. It is thought that the skeletal alterations in IMAGe association encompass retarded endochondral ossification normalized later on and mild metaphyseal dysplasia of postnatal onset.

RESUMO

Recent evidence suggests that the oxidative stress is an important factor in the pathophysiology of pre-eclampsia. The purpose of this study was to evaluate the possible relationship between increased resistance at the Doppler assessment of the uterine arteries between 20-23 gestational weeks and biochemical markers of oxidative stress, with the development of pre-eclampsia and/or growth restricted infants. This was a prospective study of 34 pregnant women with normal uteroplacental flow and 30 women with abnormal uterine arteries Doppler analysis (mean PI >or= 1.60) during the transvaginal assessment of the uterine arteries at the routine anomaly scan. Blood samples were obtained in order to assess the plasma oxidative stress, namely malondialdehyde (MDA) and uric acid levels. The MDA was significantly higher in the group of women with abnormal uterine arteries Dopplers. This group is at increased risk for the development of pre-eclampsia. The uric acid levels did not differ significantly between the two groups of women. There was no significant difference regarding the sensitivity or the specificity of the uterine arteries Doppler examination in detecting pre-eclampsia in comparison to the combination of oxidative stress and Doppler's. Our study provides additional evidence regarding the role of oxidative stress in the pathophysiology of pre-eclampsia. Whether antioxidant supplementation in the group of women with abnormal uterine Doppler's is effective in reducing the incidence of the disease remains to be established.

RESUMO

OBJECTIVE: This study was undertaken to determine the feasibility of detecting abnormal fetal growth among patients undergoing biophysical profile (BPP) and to identify the factors those influence the accuracy. STUDY DESIGN: Retrospectively singletons with reliable gestational age (GA) having a BPP were identified. Fetal growth restriction (FGR) and large-for-gestational age (LGA) were based on estimated or actual birth weight 10% or less or 90% or greater for GA, respectively. Likelihood ratio (LR), odds ratio (OR) and 95% CIs were calculated and multivariate predictive models used. RESULTS: Among the 1934 consecutive patients that met the inclusion criteria, the LR of detecting FGR was 10.9 and of LGA, 17.4. Multivariate analysis indicates that accurate classification of fetal growth is significantly better with hydramnios (OR 1.78, 95% CI 2.68), if the GA is less than 32 weeks (OR 3.71, 95% CI 1.50-9.16) or GA is between 32.1 and 36.9 weeks (OR 1.43, 95% CI 1.05-1.96). CONCLUSION: It is feasible to accurately identify abnormal growth among high-risk patients and to delineate factors that influence the correct classification of fetal growth.

RESUMO

It is presented the case of the second pregnancy of a 36 year-old patient with antecedent of preeclampsia that was solved, at full-term, with a Caesarean operation by means of which was obtained a healthy new born. The patient began her prenatal control at 29th week. Ultrasound made at her admittance showed a fetus with an approximated weight of 451 grams. The patient was hospitalized until completing protocol of study for restriction of severe fetal growth. At 34.5 weeks, an ultrasonographical control showed an alteration in venous duct; for that reason it was decided to interrupt pregnancy abdominally. There were no surgical complications and was obtained a phenotypically normal new born, male, weight of 820 grams and size of 33 cm, who was referred to the Instituto Nacional de Perinatologia. At 43.3 weeks he was discharged from hospital with a weight of 1,840 grams. At the present he's fed with fortified milk.

RESUMO

OBJECTIVE: To investigate whether intrauterine growth retardation (IUGR) and preterm delivery in a poor population of South Asia was associated with altered maternal and fetal levels of folate, vitamin B12, and homocysteine. SUBJECTS AND METHODS: Hundred and twenty-eight pregnant women from a low socio-economic strata in the city of Lahore, Pakistan were followed with ultrasound of fetal growth from the 12th week of pregnancy. Blood samples were drawn from the woman and the cord at delivery. Serum was analyzed by a chemiluminescent immunoassay for folate and vitamin B12 and by fluorescence polarization immunoassay for total homocysteine (tHcy). RESULTS: Fourty-six infants showed IUGR. In term, but not preterm, deliveries with IUGR, maternal and cord blood folate levels were half of those in deliveries of normal birth weight infants (P=0.004 and P=0.005). The risk of IUGR was reduced among women with folate levels in the highest quartile (OR 0.31, 95% CI 0.10--0.84). There was no association between vitamin B12 and IUGR. Total homocysteine levels were higher in women delivering IUGR infants (P=0.02). There was an inverse correlation between cord blood folate and tHcy levels (r=-0.26, P=0.006). We also found increased risks for hypertensive illness (OR 3.5, 95% CI 1.4--8.6) and premature delivery (OR 2.5, 95% CI 1.1--6.2) in women in the highest quartile of tHcy. CONCLUSIONS: The occurrence of IUGR increased with low maternal and cord concentrations of folate and high maternal levels of tHcy. Further studies on the effects of vitamin B supplementation through pregnancy are warranted.

RESUMO

BACKGROUND: In order to assess the organizational and economical implications of Doppler ultrasonography used in high risk pregnancies, a national estimate of the use in singleton pregnancies with risk of small for gestational age (>2 SD below mean birthweight) (SGA) or intrauterine growth retardation (IUGR) was needed. METHODS: Through retrospective analyzes of both national registry data, and local clinical and ultrasonic records from Copenhagen University Hospital annual populations of singleton pregnant women with suspected IUGR and/or infants born SGA were described. The antenatal care program for assessing pregnancies with suspected IUGR was described. RESULTS: In 1996 2.8% of all singleton infants were born SGA. The population had increased risk of perinatal mortality and morbidity, and about 40% had labor induced or were delivered by caesarean section, compared to 15% of the infants with normal birthweight. In the local population 79 (3.3%) of singleton infants were born SGA and 2/3 of these were considered SGA or IUGR before delivery. Of all singleton pregnancies, a total of 88 (3.7%) were assessed by ultrasonic fetometry because of a risk or clinical suspicion of SGA, and 49 (55.7%) of these pregnancies resulted in a SGA infants. Combining national and local data it is estimated that in Denmark, about 2000 women (3.1%) will be referred for ultrasonic fetometry each year because of a risk or clinical suspicion of SGA and have a mean of 2.5 fetometries. About 75% (1500) will be further assessed by Doppler ultrasonography and have a mean of 3.4 Doppler examinations. CONCLUSION: The annual number of Doppler ultrasonography examinations in singleton pregnancies with increased risk of or signs of IUGR is estimated to be about 5000.

RESUMO

OBJECTIVE: This study was undertaken to determine the efficacy and safety of intravenously administered iron sucrose with versus without adjuvant recombinant human erythropoietin in the treatment of gestational iron-deficiency anemia resistant to therapy with orally administered iron alone. STUDY DESIGN: Forty patients with gestational iron-deficiency anemia were randomly assigned to receive intravenously iron sucrose plus recombinant human erythropoietin or iron sucrose alone twice weekly. Target hemoglobin value was 11.0 g/dL. Efficacy measures were reticulocyte count, increase in hematocrit, and time to target hemoglobin level (treatment duration in weeks and need for continued therapy after 4 weeks). RESULTS: Both regimens were effective, but with adjuvant recombinant human erythropoietin the reticulocyte counts were higher from day 4 (P<.01), increases in hematocrit were greater from day 11 (P <.01), and the median duration of therapy was shorter (18 vs 25 days), with more patients reaching the target hemoglobin level by 4 weeks of treatment (n = 19 vs. n = 15). The groups did not differ with respect to maternal-fetal safety parameters. CONCLUSION: Adjuvant recombinant human erythropoietin safely enhanced the efficacy of iron sucrose in the treatment of gestational iron-deficiency anemia resistant to orally administered iron alone.
