Abstract
OBJECTIVE The purpose of this study is to evaluate antioxidant balance in pregnant women with meconium-stained amniotic fluid. METHODS Forty pregnant women with meconium-stained amniotic fluid and 40 pregnant women with non-meconium-stained amniotic fluid were included in the study. By checking the ischemia modified albumin (IMA) level and thiol/disulfide homeostasis in the maternal blood during labor and in newborn umbilical cord blood at the first minute after birth, antioxidant/oxidant balance was evaluated. RESULTS No statistically significant difference was found between the maternal albumin levels. Maternal IMA level was statistically significantly higher in the meconium group than in the control group (p = .045). Maternal native thiol (SH) and maternal total thiol levels were statistically significantly higher in the control group than in the meconium group (p = .042 and p = .009, respectively). No statistically significant difference was found between maternal disulfide/native thiol (p = .262), maternal disulfide/total thiol (p = .152), maternal native thiol/total thiol (p = .153) rates in both groups. No statistically significant difference was determined between the patients with meconium and the control group in terms of cord blood IMA (p = .474), Albumin levels (p = .664), cord blood Native thiol (p = .944), cord blood total thiol (p = .612) levels and cord blood disulfide/native thiol (p = .240), cord blood disulfide/total thiol (p = .276), cord blood native thiol/total thiol (p = .277) rates. CONCLUSION Determination of a decrease in SH and Total Thiol levels in maternal serum and an increase in the meconium group's IMA level was interpreted as a shift of antioxidant balance toward oxidant in this group.

Abstract
Advanced maternal age is associated not only with a significant reduction in fertility but also with an additional risk of developing pregnancy-related disorders. Most of these disorders are now believed to be the clinical manifestation of an incorrect placentation, namely deficient transformation of maternal spiral arteries and ineffective trophoblast invasion through uterine stroma. In the present study it was hypothesized that an age-related loss in uterine redox homeostasis interferes with the function of extravillous trophoblasts (EVTs) and placentation. To test this hypothesis, relative levels of oxidatively modified proteins were evaluated in human samples from placenta and placental bed, and the role of specific oxidative modifications to proteins in placentation was studied using a cell culture model of EVTs. In the placental bed, the carbonylation level of a 66 kDa protein (identified as albumin) presented a strong, positive and significant correlation with maternal age. Albumin was immunodetected preferentially in endothelial cells and connective tissue between muscle fascicles. In vitro results showed that carbonylated albumin overload did not alter cell viability, but reduced EVTs motility and triggered cell stress response pathways. Moreover, EVTs presented decreased ability to adhere to and invade a collagen extracellular matrix pre-treated with carbonylated albumin. In conclusion, reproductive ageing is accompanied by an increase in maternal uterine carbonylated albumin, that may have a deleterious role in the modulation of EVTs function.

Abstract
Objective: To investigate cord blood ischemia-modified albumin (IMA) levels in pregnancies with intrauterine growth restriction (IUGR) and to determine its association with abnormal fetal Doppler findings.Methods: Umbilical cord IMA levels were assessed in 34 pregnant women with IUGR and 32 pregnancies with normal fetal development. Associations of IMA with abnormal umbilical artery Doppler findings, preeclampsia, and oligohydramnios were investigated. IMA was measured using a colorimetric test based on a decrease in cobalt binding.Results: No significant between group differences in maternal age, body mass index, gravida, and parity were identified. The mean gestational age at delivery was earlier in the IUGR group than in the control group (35.7 ± 3.2 versus 38.4 ± 1.2, respectively). The mean cord blood IMA values for the IUGR group were significantly increased compared to those in the control group (0.565 ± 0.22 versus 0.250 ± 0.12, respectively, p = .001). There was a significant positive correlation between umbilical artery pulsatility index and IMA levels in the IUGR group. Patients with preeclampsia, oligohydramnios, and abnormal nonstress test results in the IUGR group had significantly higher IMA levels. Patients with systolic to diastolic ratios >3 and pulsatility index (PI) above the 95th percentile in the IUGR group had significantly higher cord blood IMA levels (p = .001 and p = .007, respectively).Conclusions: Cord blood IMA values may be a useful marker for perinatal asphyxia. Abnormal Doppler findings are associated with increased IMA levels in complicated pregnancies with IUGR.

Abstract
Background:Ischemia Modified Albumin (IMA) is considered as an early marker of ischemia. Its levels may be altered in any clinical condition where an ischemic event is involved. Skeletal muscle ischemia is associated with severe exercise but may also occur in moderate form of exercise.Objective:The levels of IMA were estimated before and after thirty minutes of moderate exercise in students undergoing athletic training.Methods:The present study was conducted on 120 young adult students undergoing athletic training program in the physical education department. All the subjects were healthy with normal body mass index and blood pressure. Their serum samples were collected before and after running for half an hour on the racing track and were analyzed for IMA colorimetrically and the data was subjected to appropriate statistical analysis.Results:The levels of IMA were found to be statistically significantly higher after exercise as compared to those before exercise (p = 0.005). The ratio of IMA to albumin (IMAR) was also found to be significantly higher after exercise as compared to that before exercise (p=0.000).Conclusion:It may be concluded that the skeletal muscle ischemia induced by moderate aerobic exercise is associated with an increased conversion of albumin to IMA.

Abstract
BACKGROUND/AIMS A meta-analysis of maternal serum ischemia-modified albumin (IMA) and fetal cord-blood IMA concentrations in normal pregnancy (NP) compared to non-pregnant healthy controls (HC) and in preeclampsia (PE) compared with normal pregnant controls were studied. METHODS All major databases were searched for eligible studies. We included eight studies comparing serum IMA between NP and HC, 14 studies comparing serum IMA between PE and NP and five studies comparing cord-blood IMA between PE and NP groups. Meta-analyses on these included studies were performed using Review Manager 5.3. Pooled-overall effect size as standardized mean difference (SMD), publication bias, subgroup, and sensitivity analysis data were generated. RESULTS Random-effects meta-analysis indicated a significant increase in serum IMA in the NP group (SMD = 0.98, p = .01) and the PE group (SMD = 0.94, p < .0001) as compared with HC and NP groups, respectively. And, the cord-blood IMA has been found to be significantly increased in PE (SMD = 6.51, p < .0001) compared with the NP group. CONCLUSIONS This meta-analysis, the first of its kind showed that the increased serum IMA concentrations were indicative of increased oxidative stress in NP and PE. Measurement of maternal serum IMA and fetal cord-blood IMA concentrations were useful as simple, novel, and inexpensive markers of oxidative stress (OS) status in PE patients. Future large-scale studies are needed to explore IMA in relationship to the disease severity in PE.

Abstract
BACKGROUND Pre-eclampsia (PE) carries an increased risk for maternal and/or fetal mortality or serious morbidity. PE is associated with ischemia and increased oxidative stress in the placenta, which may lead to modification of plasma albumin to ischemia-modified albumin (IMA). The aim of this study was to investigate IMA and hematological parameters in mothers and in premature infants in normal and in pre-eclamptic pregnancies. METHODS Twenty-five pregnant women with PE and their premature newborns were categorized as the PE group, and 25 normotensive pregnant women and their premature newborns as the control group. Preterm infants are classified as small for gestational age (SGA) or non-SGA according to the Fenton preterm growth chart. Serum IMA, complete blood count (CBC), liver function tests (LFT), renal function tests (RFT), albumin, and C-reactive protein were measured in the mothers immediately before birth, and in the cord blood and serum of the newborns at 6 and 24 h after birth. Clinical and demographic data were recorded for both groups. RESULTS While IMA, LFT and RFT were significantly increased in the PE group compared with the control group, albumin and CBC were significantly lower in the PE group. A total of 40% of PE newborns were SGA, 30% of whom had severe SGA (birthweight <3rd percentile). Cord IMA was significantly increased in all preterm neonates in the PE group compared with the control group. No mothers or neonates died. CONCLUSION Serum IMA in addition to the prevalence of SGA were significantly increased in the PE group. Cord blood IMA, therefore, might be a predictive biomarker for SGA in PE pregnancies.

Abstract
BACKGROUND Ectopic pregnancies constitute about 2% of all pregnancies which are the leading cause of pregnancy-related deaths and a considerable cause of maternal morbidity. Oxidative stress can lead to a number of pregnancy related diseases including miscarriage, eclampsia and preterm labor. Ischemia modified albumin (IMA) which reflects the oxidative stress may be used as a marker for ectopic pregnancy. Our aim was to compare the levels of IMA and total antioxidant status (TAS) in ectopic and normal pregnancies and to understand if IMA can be used as a marker to diagnose ectopic pregnancy. MATERIALS AND METHODS Our case-control study consisted of 38 women with ectopic and 42 women with normal pregnancy. IMA and TAS levels were determined in serum samples with an albumin-cobalt binding test and by commercially available kits, respectively. IMA levels were adjusted according to serum albumin levels. Index of oxidation (IOS) was calculated by dividing adjusted IMA (A-IMA) levels with TAS. A receiver operating characteristics (ROC) curve analysis was made and cut-off values for the biomarkers were investigated in SPSS 21.0 program (SPSS, Chicago, IL). Data were presented as mean ± standard deviation and a p value < .05 was accepted as statistically significant. RESULTS There was a statistically significant difference in IMA, A-IMA, and IOS levels between ectopic and normal pregnancies. Although TAS level was not different statistically, it was lower in ectopic pregnancy. According to ROC curve analysis, IOS had the largest area under curve. A cut-off value of 0.545 for IOS had 81.6% sensitivity and 59.5% specificity. CONCLUSIONS According to our study, oxidative stress plays an important role in ectopic pregnancy and either A-IMA or IOS can be evaluated as a marker of ectopic pregnancy after further studies.

Abstract
Ischemia modified albumin is a novel marker of ischemia generated due to hypooxygenation and increased hydroxyl free radicals in low pH. The molecule has been licenced for clinical use as an early marker for acute coronary syndrome in cardiology. Since presence of ischemia might have serious and sometimes devastating effects in perinatology, various researches have evaluated its value in different clinical conditions. This narrative review aims to summarize the literature concerning the value of IMA in perinatology and guide for further research.
