Abstract
Abstract Background and objectives: Despite prenatal care, pre-eclampsia is still one of the most important causes of maternal and fetal mortality. There is no screening test for pre-eclampsia to be reliable and economical. One of the most accessible and easiest screening tests is blood uric acid measurement. The goal of this study is to assess the level of uric acid in high risk pregnant women a few weeks before emerging the manifestations of pre- eclampsia. Materials& Methods: In this study carried out in Isfahan medical centers, 124 pregnant women with gestational age of 24-28 weeks were selected by simple non-probability sampling. Then the subjects' uric acid were measured and considered high if it would be more than 4.5mg/dl. Results: of all the subjects, only 20 (16.1%) suffered from preeclampsia. 10 of 39(31.4%) who had high uric acid(more than 4.5mg/dl) showed pre-eclampsia.It is true for low uric acid women(68.6%), that is , the number of pre-eclampsia was ten. Conclusion: Relative risk of increased level of uric acid in preeclampsia at 24-28 weeks of gestational age was 2.2. Chi-square test showed that there is significant difference between the level of uric acid at 24-28 weeks of gestational age and the Incidence of preeclampsia.

Abstract
Background and Objective: Pre-eclampsia is the most common cause of maternal and neonatal mortality. Recent studies show that there may be a relationship between chorionic gonadotropine (HCG) and pre-eclampsia. Thus we aimed at assessing the serum level of βhCG after 28th week of pregnancy in mild pre-eclamptic and healthy pregnant women.
Material and Methods: In this case-control study, we measured the level of βhCG in 26 pre-eclamptic and 26 normal pregnant women. The difference between groups was analyzed by Mann-Whitney test (P≤ 0.05).
Results: The mean of βhCG in the case (73192 ± 42956 IU/L) and control group (34038 ± 21272 IU/L) is different significantly (P= 0.001). Considering mother’s age, gestational age and parity, there is a significant difference between the two groups (P=0.001).
Conclusion: The results of our study show that the higher level of βhCG, the greater the risk of pre-eclampsia.
Key words: Pre eclampsia, βhCG, Parity

Abstract
ABSTRACT
Background and Objective: Nutritional factors and activation of inflammatory pathways are thought to be involved in pathogenesis of preeclampsia in pregnant women. The present study aimed to compare the serum levels of vitamin D and interleukin-6 in healthy pregnant women with those of preeclampsia ones.
Methods: This case-control study was performed on 120 healthy pregnant women and 120 women with preeclampsia referred to Imam Reza Hospital in Kermanshah. The serum levels of vitamin D and IL-6 were measured by ELISA method. The data was analyzed by SPSS software (version 20) using independent t-test, the P-value of <0.05 was considered as statistically significant.
Results: There was no statistically significant difference between the mean level of vitamin D in the patients (37.64 ± 29.50 ng/ml) and the controls (40.06 ± 33.20 ng/ml). the serum level of IL-6 in patients with preeclampsia (21.71 ± 32.24 pg/ml) was significantly higher compared to that of control group (15.04 ± 28.6 pg/ml) (P <0.001).
Conclusion: Based on the findings of this study, inflammatory factors and cytokines such as IL-6 can be considered as risk factor for preeclampsia. However, more studies with larger sample sizes are required to further evaluate the association of vitamin D levels and risk of preeclampsia.
Keywords: Pregnancy, Pre-Eclampsia, Vitamin D, Interleukin-6.

Abstract
ABSTRACT
Cardiovascular disease (CVD) is one of the most important causes of mortality worldwide. Several risk factors have been proposed to be associated with CVD. The main risk factors include family history, smoking, hypertension, history of diabetes, hyperlipidemia and obesity. However, new factors have been recently proposed to be associated with CVD. These include blood homocysteine, fibrinogen, plasma factor VII activity, lipoprotein (a) and several other factors. Nowadays, the role of homocysteine in the development and exacerbation of several diseases has been demonstrated. Extensive studies have been performed on the role of homocysteine in diabetes, preeclampsia, depression, Alzheimer's disease and multiple sclerosis. Homocysteine level increases with age. Moreover, absorption of micronutrients, especially vitamin B12, decreases in old age that could cause a further increase in homocysteine level. On the other hand, elasticity of blood vessels decline with aging, and increased levels of homocysteine accelerate atherosclerosis. The sum of these processes highlights the role of homocysteine in the development and exacerbation of several diseases.

Abstract
Background: Thyroid disorders are the most common cause of endocrine dysfunction among women of childbearing age. It is well-established that hypothyroid dysfunction can have significant adverse effects on pregnancy and fetal development. This study aimed to determine the prevalence of thyroid disorders among antenatal women and assess the maternal and fetal outcomes in pregnant women with hypothyroid disorders.
Methods: This prospective study was conducted in the antenatal clinic of the Department of Obstetrics and Gynaecology in association with the Biochemistry Department. After obtaining written informed consent, antenatal women aged 18-40 years were included in this study, regardless of their gestational period. Venous blood samples were collected from the antecubital vein, and thyrotropin, free triiodothyronine (free T3), and free thyroxine (free T4) levels were measured. Hypothyroid antenatal women were monitored throughout their pregnancies to evaluate maternal and fetal outcomes.
Results: Among the participants in this study, 149 antenatal women had thyroid disorders, with a prevalence rate of 12.6%. Subclinical hypothyroidism, overt hypothyroidism, subclinical hyperthyroidism, and overt hyperthyroidism were observed in 6.9%, 3.2%, 1.8%, and 0.7% of cases, respectively. Maternal complications included oligohydramnios (5.8%), preeclampsia (13.3%), and preterm delivery (5%), while fetal complications included low birth weight (20.8%), hyperbilirubinemia (9.1%), and neonatal intensive care unit (NICU) admissions (13.3%).
Conclusion: A high prevalence (12.6%) of thyroid disorders, particularly hypothyroidism (10.1%), among pregnant women, emphasizing the importance of routine thyroid testing for all antenatal individuals.

Abstract
Background: Hypertensive disorders, particularly preeclampsia (PE), complicate 2–8% of pregnancies and significantly contribute to maternal and perinatal mortality. PE disproportionately affects low-resource regions, accounting for 26% of maternal deaths in Latin America and 9% in Africa and Asia. Risk factors include extreme maternal age, chronic hypertension, obesity, diabetes, and racial disparities (Higher incidence in Black and Hispanic populations). The exact cause remains unclear, but angiogenic imbalance and immune dysregulation play key roles. This review focuses on the role of cytokines and chemokines in developing preeclampsia (PE).
Methods: A narrative review was conducted to examine studies on the immunological and vascular mechanisms of preeclampsia, with a focus on recent systematic reviews and high-impact research.
Results: The results highlighted a critical imbalance between pro-inflammatory (IL-6, TNF-α) and anti-inflammatory (IL-4, IL-10) cytokines in PE pathogenesis. Notably, reduced second-trimester IL-10 levels served as an early predictive biomarker. Endothelin-mediated vasoconstriction and Th1/Th2 immune imbalance further exacerbated endothelial dysfunction, a central feature of PE. While human and animal studies support these findings, precise mechanistic pathways remain elusive.
Conclusion: Cytokine and endothelin can serve as promising biomarkers and therapeutic targets for PE. Early IL-10 detection may improve risk prediction, but no causal links have been confirmed yet. Gaining a better understanding of these mediators could improve clinical strategies and help minimize complications. Future longitudinal research should focus on biomarkers and explore anti-inflammatory treatments for PE prevention.

Abstract
Pregnancy-induced hypertension is a spectrum of multi-systemic dysfunction in pregnancy, usually seen in the third trimester in approximately 6–8% of pregnancies in the United States, according to the National High Blood Pressure Education Program (NHBPEP). The World Health Organization reported that this multisystem disorder accounts for 16% of maternal deaths in developed countries and 1.8%-16.7% in most developing countries.
The spectrum can progress from Preeclampsia to Eclampsia with short- and long-term complications that may impact significantly on the quality of life of both the fetus and the mother. Though the pathogenetic mechanisms remain unclear, evidence supporting the roles of genetic, immunologic, and environmental factors is rapidly evolving. Preeclampsia, an initial spectrum of the disorder, begins with abnormal placentation with failure of adaption, inflammatory changes, permanent vascular and metabolic damages, and increasing risk of cardiovascular, renal, endocrine, neurological, hematological, and socioeconomic complications. Regardless of the postulation, oxidative stress, placenta ischemia hypoxia with release of toxic substances, and endothelial dysfunction are essentially pivotal to multiple organ damage. American College of Obstetrics and Gynecology (ACOG) recommends starting treatment for Preeclampsia when the diastolic blood pressure (DBP) is above 105–110 mm Hg. This article describes the proposed pathophysiological mechanism associated with the spectrum of maternal complications in Pregnancy-induced hypertension.
