Birth weight was improved, and no excess of maternal or fetal aspirin-related side effects occurred. It would seem prudent to consider low-dose aspirin therapy in selected patients with risk factors for IUGR Table 1. Approximately one half of infants with IUGR have intrapartum asphyxia and lower Apgar scores than control subjects.
A higher incidence of meconium aspiration has also been noted in these infants. Therefore, continuous monitoring of fetal heart rate throughout labor is recommended in cases of IUGR. Late decelerations are more predictive of fetal hypoxia and a resultant adverse outcome in this group of high-risk infants.
A lower threshold for the choice of cesarean section is therefore recommended. Neonatal resuscitation and subsequent care of the growth-restricted infant should follow in the same manner used with other newborns. Problems to closely watch out for in infants with IUGR include hypoglycemia, hypocalcemia, polycythemia secondary to intrauterine hypoxia and hypothermia due to decreased body fat. In most cases, infants with IUGR ultimately have good outcomes, with a reported mortality rate of only 0.
Some early studies 28 , 29 have found a variety of long-term complications in infants with IUGR. These complications include hyperactivity, clumsiness and poor concentration. Other studies 30 , 31 have found growth-restricted infants to be at increased risk for development of hypertension, abdominal obesity and type 2 non—insulin-dependent diabetes as adults. In a recent British study, 32 records of 1, men and women born between and for whom birth weight and anthropomorphic measurements were recorded in detail after birth were examined.
No definite association was found between cognitive function intelligence quotient and vocabulary and birth weight, head circumference or ratio of head circumference to abdominal circumference. Collectively, developmental studies demonstrate that many factors contribute to the ultimate intellectual development of infants with IUGR, including birth weight, time of onset of IUGR, head circumference, gestational age at delivery, etiology of the IUGR and postnatal environment.
Most infants with IUGR have an excellent long-term prognosis. Already a member or subscriber? Log in. Interested in AAFP membership? Learn more. Clair Medical Center, Morehead, Ky.

Clin Obstet Gynecol. In our study, only patients with diagnosed IUGR without hypertension were included and no oxidative stress in plasma was noted. Similar results were obtained by Celik et al. Increased protein carbonyls [ 54 ] and a higher level of plasma GPx [ 18 ] as well as reduced antioxidant capacity [ 54 ] and an elevated level of MDA in plasma patients with IUGR [ 17 , 55 ] were observed.
Similar to our research, the alteration of erythrocyte antioxidant enzymes in IUGR was noted. Saker et al. The increase of MDA and lipid peroxidation levels in the maternal erythrocytes was also observed, which can be a marker of severe OS [ 56 , 57 ]. These differences are listed as follows: a In other publications, the diet was not analysed, and if the nutrition regime is not appropriate, it can influence oxidative stress in IUGR. Unfortunately, we did not collect data on environmental stressors or physical activity.
None of them drank alcohol or smoked cigarettes during pregnancy. According to recently published data, pregnant women from Warsaw perceived relaxation as a safer behaviour rather than regular exercise and maintaining an active lifestyle.
Thus, physical activity was not satisfactory [ 59 ]. The exposure to organochlorine pesticides measured as the level in human milk was higher in Poland than in other European countries.
The air over Poland is one of the most polluted in Europe. In the Warsaw population, the weighted exposure of NOx is 3. The degree of pollution strongly depends on which region in Warsaw with the highest values at the left side of the Vistula River and what part of the year—with the highest pollution in the winter time [ 62 ].
It neutralizes aldehydes generated endogenously, e. Among the patients with IUGR, we observed a significantly higher gingival index, a number of teeth with cavities, and missing teeth. The stress can be classified as mild to moderate since only the induction of antioxidant enzymes was observed, without the changes in the lipid peroxidation marker MDA. So far, no influence of dental cavities on IUGR incidence was detected [ 66 ]. Some authors suggest that advanced periodontal diseases may be related to more frequent adverse pregnancy outcome including preterm birth [ 67 , 68 ].
However, in our study group where no signs of advanced periodontal disease were present , preterm delivery was not observed. Interestingly, similar to Mert et al. The intake of flavonoids and vitamins in the IUGR group in our study was comparable to that of the control group. ORAC is one of the methods to measure total antioxidant status in vitro. ORAC level was shown to strongly correlate with uric acid concentration [ 70 ].
The compound is easily oxidized; thus, it serves as an antioxidant in vitro in the hydrophilic environment [ 71 ]. However, in vivo , it can reveal prooxidant action as well. When the uric acid reacts with oxidants, other radicals may be produced which might propagate a radical chain reaction and lead to oxidative damage to cells.
Moreover, uric acid may be involved in intracellular oxidant production via the ubiquitous NADPH oxidase-dependent pathway resulting in redox-dependent intracellular signalling and, in some conditions, oxidative stress [ 72 ]. Thus, not all antioxidants in vitro serve as antioxidants in vivo , and the results should be interpreted with caution.
In foetuses with IUGR, there is a strong evidence of a higher level of uric acid level in cord vein blood [ 73 ] and alteration in the compound in urine of neonates [ 74 ]. Uric acid together with pseudouridine and allantoin are metabolites involved in nucleoside metabolism [ 75 ].
Its increase may be related to the hypoxia or ischaemia, together with intermittent perfusion in IUGR. As an example, it was proven that uric acid changes in this marasmus model but it was not observed to change in kwashiorkor children [ 75 ].
Thus, further study should be performed to clarify the obtained results. Currently, we suppose that higher ORAC was not only related to metabolic changes. It reflected higher antioxidant content not related to uric acid in plasma in IUGR as well, especially since a lower MDA level in the group was observed. As an example, a higher ORAC was noted in children with dental cavities [ 77 ].
Therefore, prospective studies designed to monitor the OS level from the first trimester of pregnancy to postpartum in patients with IUGR are required. Saliva is an alternative material to blood. In our study, a significant correlation between ORAC in saliva and plasma was observed. Similar results were previously obtained for patients with gestational diabetes [ 78 ].
Saliva was also considered valuable for estimating the variation of total antioxidants in plasma of triathletes during the training season [ 79 ]. However, regarding lipid peroxidation markers MDA , we observed no correlation in saliva and plasma. Similar results were observed previously among gestational diabetic patients [ 78 ] and it was concluded that the concentration of MDA in saliva is strongly dependent on the oxidative balance of saliva and the state of the oral cavity. However, in some pathologies related to strong oxidative stress, such correlation was observed.
For example, in patients with recurrent aphthous ulcerations, both salivary and serum malondialdehyde MDA were elevated and strongly correlated with one with another. A similar phenomenon was observed in type 2 diabetes [ 80 ]. The correlation between salivary and serum oxidative biomarkers reinforces the utility of saliva as a valid diagnostic fluid. This model of monitoring may reduce adverse perinatal outcomes. Oxidative stress markers differ in two placental dysfunction pathologies: pregnancy-induced hypertension and IUGR.
In this study, among patients with PIH, no sign of oxidative stress was observed. The major strength of this research is the analysis of the diet, inflammation markers, and oral health, which can strongly influence the oxidative status.
To the best of our knowledge, this study is the first to assess OS in PIH using dietary data to interpret the results. Oxidative stress was detected in patients with IUGR. Although no differences in the activity of antioxidant enzymes were found in plasma, the differences in the whole blood were observed. Moreover, among patients with IUGR, a significantly higher activity of salivary ALDH was observed and this may be explained by the inflammation in the oral cavity within this group due to poor oral health status.

Introduction Placental dysfunction is a consequence of an inadequate remodelling of uterine and placental spiral arteries. Materials and Methods The OS parameters and the antioxidant defence systems in two diagnostic materials were determined: standard blood: plasma and whole blood and alternative saliva.
Study Group Fifty-seven pregnant women with pregnancy pathologies , and 47 women with uncomplicated pregnancy between 24 and 41 weeks of gestation were enrolled. Sample Collection Blood and saliva samples were collected in the morning after an overnight fast at least 6 hours. Biochemical Analysis Results are the average of three independent measurements.
Diet Dietary nutrient intake was calculated using SFFQ, consisting of a list of foods with standard serving sizes commonly consumed by the Polish adult population. Oral Health Each patient received a complete oral and periodontal examination. Table 1. Table 2. Table 3.

Preeclampsia affects the blood flow to the placenta, often leading to smaller or prematurely born babies. Ironically, sometimes the babies can be much larger, but scientists are not certain that preeclampsia was the cause. While maternal death from preeclampsia is rare in the developed world, it is a leading cause of illness and death globally for mothers and infants. Preeclampsia is often silent, showing up unexpectedly during a routine blood pressure check and urine test.
The impact of preeclampsia is more profound if it occurs earlier in the pregnancy, or in a woman who had high blood pressure before pregnancy. Care providers may recommend time off work, bed rest, medication and even hospitalization to keep the blood pressure under control. Keeping the baby in-utero as long as possible, assuming growth continues, is preferred for the long-term health of the baby. Unfortunately, the only "cure" for the disease begins with delivery of the baby and placenta, which is sometimes recommended before the pregnancy goes to term in the best interest of the mother.
Doctors may prescribe anti-hypertensive medications. Preeclampsia can appear at any time during pregnancy, delivery and up to six weeks post-partum, though it most frequently occurs in the final trimester and resolves within 48 hours of delivery. Preeclampsia can develop gradually, or come on quite suddenly, even flaring up in a matter of hours, though the signs and symptoms may have gone undetected for weeks or months.
In some instances, preeclampsia does not appear until during the delivery, or the 48 hours that follow, but it has been known to occur up to six weeks post-partum. While obviously not dangerous for the baby, post-partum preeclampsia is still critical for the mother. Sleep deprivation, post-partum depression, more attention on the newborn, and a lack of familiarity with normal post-partum experiences all contribute to more easily ignoring or missing indicators of a problem.
Any of the signs and symptoms described above should be cause for concern, and you should immediately contact your health care provider if you experience any of them.
A baby is considered premature if he or she is born before 37 weeks, but more severe issues occur when a baby is born earlier than 32 weeks. Babies born later than 32 weeks in developing countries may have more severe problems than babies born in high resource countries since those countries often lack the resources that preemies need.
The effects of being born early can vary widely. Some babies may spend only a day or two under close observations while others may spend the first months of their life in the Neonatal Intensive Care Unit NICU. Some babies may also have lifelong problems such as learning disorders, cerebral palsy, epilepsy, blindness, and deafness. Having a premature baby can also mean a great deal of emotional and financial stress for a family.
Preeclampsia can cause reduced blood flow to the mother's placenta, restricting the supply of food to her baby. As a result, the baby may become malnourished and be small for its gestational age. Ultrasounds can help identify IUGR. Many babies who suffer from IUGR can catch up on their growth within a few months, although recent research suggests that growth restricted infants are more prone to adult diseases including diabetes, congestive heart failure and hypertension.
Acidosis The baby survives in the womb by receiving nutrients and oxygen through the placenta. Delivery is essential at this point, even if the baby is premature.
Infant death is one of the most devastating consequences of preeclampsia. In the U. Many countries do not have the means to keep a premature baby alive, so the rate of neonatal death in these countries is therefore much higher. Stillbirths from preeclampsia babies that die in utero after 20 weeks of gestation number between 1, and 2, in the U. Stillbirths are much more likely to occur with severe preeclampsia, HELLP syndrome or preeclampsia superimposed on chronic hypertension.
Preeclampsia can appear and progress very quickly. Please err on the side of caution and contact your doctor or midwife immediately if you experience warning signs of preeclampsia. An integrated system of maternal and newborn care can reduce some of these deaths. However, we ultimately need more research. We need to find a cure.
Ongoing life challenges Preeclampsia has been linked to a host of lifelong challenges for infants born prematurely, among them learning disorders, cerebral palsy, epilepsy, blindness and deafness. With prematurity also comes the risk of extended hospitalization, small gestational size and the interruption of valuable bonding time for families.
Prematurity stresses a family unit, and this stress is compounded when the mother is also ill. When preeclampsia develops, the mother and her baby are monitored carefully.
There are medications and treatments that may prolong the pregnancy, which can increase the baby's chances of health and survival. Once the course of preeclampsia has begun, it cannot be reversed and the health of the mother must be constantly weighed against the health of the baby.
In some cases, the baby must be delivered immediately, regardless of gestational age, to save the mother's or baby's life.
We say the cure begins with delivery because women are still at risk for preeclampsia and other hypertensive disorders of pregnancy, after delivery.
It is imperative that postpartum mothers continue to monitor their health for at least six weeks after delivery. Find out more www. Right now, early diagnosis through simple screening measures and good prenatal care can predict or delay many adverse maternal outcomes of preeclampsia.
Prompt treatment saves lives. Research is beginning to provide insight into some of the molecular abnormalities present in preeclamptic women and it is hoped that these recent discoveries may lead to development of a cure. Researchers suggest there are probably several different variables, some maybe genetic in origin, that predispose a woman to getting preeclampsia and that a preventive or curative therapy for one woman may not work for all women.
Although the Preeclampsia Foundation helps fund research, much more is needed. Sadly, preeclampsia is still one of the lowest funded research areas in terms of what health economists call Disability Adjusted Lost Years DALYs , and we think the pregnant woman deserves a better deal. Policymakers, scientific investigators, health care professionals and patients need to work together to bring the information we already have to those who need it most and to drive greater awareness and resources to this devastating problem.
