Abstract
PURPOSE Little is known about the effects of leptin and leptin receptor polymorphisms on lipid changes during pregnancy. The aims of this study were to evaluate the associations between the single nucleotide polymorphisms (SNPs) of leptin and leptin receptor genes and the lipid concentrations during pregnancy; and to test whether dietary intake is a mediator in these associations. METHODS A prospective cohort of 154 pregnant women was followed up in Rio de Janeiro, Brazil during the following gestational periods: 5-13th, 20-26th and 30-36th weeks. HDL-C, total cholesterol (TC) and triglyceride (TG) were measured by the enzymatic colorimetric method, and LDL-C was calculated. DNA was extracted by the phenol-chloroform method, and leptin (G2548A, rs7799039) and leptin receptor SNPs (Q223R; rs1137101 and K109R; rs1137100) were genotyped using real-time PCR. Statistical analyses included linear mixed-effect models. RESULTS Women with the AA genotype of G2548A polymorphism reported a higher fat and total energy intake and had a higher increase in TG concentration during pregnancy than women with AG or GG genotype. The association between G2548A SNP and TG concentrations was not attenuated by adjusting for total lipid (g) and energy (kcal) intake. We did not observe significant associations between the Q223R and K109R SNPs and the lipid concentrations. CONCLUSIONS Women homozygous for the A allele of the leptin SNP (G2548A) had a higher increase in TG concentrations per gestational week compared with women with the AG or GG genotype. This is an exploratory and hypothesis-generating study, and the results need confirmation in studies with larger sample sizes.'

Abstract
BACKGROUND The genetic component related to blood pressure (BP) changes during pregnancy is still not elucidated. Thus, the aim of the study was to evaluate the association between leptin and leptin receptor polymorphisms and systolic (SBP) and diastolic BP (DBP) variation during pregnancy and the postpartum period. METHODS Prospective cohort of 146 women followed at a Public Health Center in Rio de Janeiro, Brazil, during pregnancy and the postpartum. SBP and DBP (mm Hg) were measured using an automatic sphygmomanometer. DNA was extracted by phenol-chloroform protocol and leptin (G2548A) and leptin receptor genes (Q223R and K109R) polymorphisms were genotyped using real-time PCR method. Statistical analyses included longitudinal linear mixed-effect models. RESULTS Adjusted longitudinal models showed that women carrying the G-allele of leptin gene's polymorphism began pregnancy with higher BP levels compared to the AA genotype and their levels remained higher throughout pregnancy and the postpartum period (β SBP = 4.5; 95% confidence interval (CI) = 1.0-8.0; P = 0.012; β DBP = 2.9; 95% CI = 0.1-5.8; P = 0.040). There was a significant interaction between leptin gene polymorphism and body mass index (BMI), in which the effect of BMI on increasing BP was steeper in women homozygous for the A-allele, compared with those who had at least one G-allele (β G-allele#BMI = -0.8; 95% CI = -1.5 to -0.1; P = 0.022). We did not find significant associations between leptin receptor polymorphisms and BP changes. CONCLUSIONS The G-allele of leptin gene polymorphism (G2548A) was associated with increased BP levels during pregnancy and the postpartum. Furthermore, leptin polymorphism genotypes seem to modify the well-known effect of BMI on BP.

Abstract
INTRODUCTION Leptin is an adipokine which has a direct relationship to obesity. Our aim was to measure this hormone in pregnant women at three months intervals throughout their pregnancies to determine the serum value of those who developed preeclampsia. MATERIAL AND METHODS We followed 19 women (median age 24.8 +/- 5.7 years) with pre-gestational Body Mass Index (BMI) less than 25 kg/m2, 21 (median age 26.1 +/- 4.6 years) with BMI higher than 25 kg/m2 and 16 (median age 30.9 +/- 5.8 years) with Gestational Diabetes Mellitus (GDM) (median age 30.9 +/- 5.8 years), recruited in the 1st trimester of pregnancy. Serum levels of leptin were measured with radioimmunoassay (RIA) technique. RESULTS In the first trimester of pregnancy leptin levels showed statistically significant differences between normal weight and overweight-obese women (p < 0.001), diabetic women (p < 0.05) and the subgroup of preeclamptic women (p < 0.001). For those women with PGBMI > or = 40 kg/m2 and leptin > or = 40 ng/ml in the second trimester, the Odds Ratio (OR) to develop preeclampsia was of 47.95% CI (4.1-527.2). Analyzing leptin values with ROC curves, the greatest area under the curve (AUC) was for leptin in the second trimester (0.773, CI: 0.634-0.911). CONCLUSION Women with morbid obesity (BMI > or = 40 kg/m2) had significantly higher levels of serum leptin (p < 0.01) and a value of 40 ng/ml of this hormone seems to be predictive of developing preeclampsia in this group of patients.

Abstract
OBJECTIVES To investigate −2548 G/A polymorphism of LEP gene, plasma leptin and soluble leptin receptor in preeclampsia/pregnancy induced hypertension. METHODS Sixty-two patients and 63 controls (normal pregnancies) studied in the third trimester. Leptin and soluble leptin receptor measured by enzyme immunosorbent assay and −2548 G/A polymorphism by polymerase chain reaction followed by restriction enzyme digestion. RESULTS Frequency of the AA genotype was significantly (p < 0.001) higher in patients. The A allele conferred a relative risk of 1.67 for the disease (p < 0.0001). Preeclampsia/pregnancy induced hypertension significantly (p < 0.001 to 0.0001) affected leptin and soluble leptin receptor concentrations, free leptin index and leptin normalized to body mass index. Genotype significantly (p < 0.05) influenced only the soluble leptin receptor concentrations. CONCLUSIONS Preeclampsia/pregnancy induced hypertension appears to be associated with higher circulating leptin and lower SLR levels, and with the AA genotype of −2548 G/A polymorphism of the leptin gene.

Abstract
AIM To determine the clinical presentation, biochemical findings, complications, clinical diagnosis and management of patients with acute fatty liver of pregnancy (AFLP). The influence of the mode of delivery on maternal-perinatal mortality is analyzed and two methods of diagnostic imaging are compared. MATERIAL & METHODS Eleven cases of AFLP identified at the West China Second Hospital of Sichuan University from January 2003 to June 2008 were studied. To provide additional evidence, 342 cases of AFLP were reviewed retrospectively from original articles researched in the China National Knowledge Infrastructure between the same period. RESULTS All cases presented with a prodrome of nausea, vomiting, malaise and jaundice. Raised transaminases and serum bilirubin were found in all patients (100%), hypoglycemia was found in two patients (18.2%) and hypoproteinemia was found in five patients (45.5%). All cases were confirmed by diagnostic criteria and clinical assessment. Diagnostic imaging helped to confirm the diagnoses. Ultrasound was used to diagnose nine patients (81.8%), and two (18.2%) patients were diagnosed by computerized tomography. Except for one patient whose labor was induced with oxytocin because of fetal death before admission, all other pregnancies were terminated by cesarean section within 24 h of definitive diagnosis. All patients and neonates survived delivery. One (9.1%) maternal death and one (7.2%) fetal death occurred. CONCLUSIONS Early diagnosis, termination of pregnancy by Cesarean section as soon as possible and comprehensive therapy are crucial for improving the prognoses of both mother and newborn.

Abstract
Adiponectin, the most abundant protein secreted by white adipose tissue, is known for its involvement in obesity-related disorders such as insulin resistance, type 2 diabetes mellitus and atherosclerosis. Moreover, modulation of the circulating adiponectin concentration is observed in pathologies that are more or less obesity-related, such as cancer and rheumatoid arthritis. The wide distribution of adiponectin receptors in various organs and tissues suggests that adiponectin has pleiotropic effects on numerous physiological processes. Besides its well-known insulin-sensitizing, anti-inflammatory and antiatherosclerotic properties, accumulating evidence suggests that adiponectin may also have anticancer properties and be cardioprotective. A beneficial effect of adiponectin on female reproductive function was also suggested. Since adiponectin has numerous beneficial biological functions, its use as a therapeutic agent has been suggested. However, the use of adiponectin or its receptors as therapeutic targets is complicated by the presence of different adiponectin oligomeric isoforms and production sites, by multiple receptors with differing affinities for adiponectin isoforms, and by cell-type-specific effects in different tissues. In this review, we discuss the known and potential roles of adiponectin in various tissues and pathologies. The therapeutic promise of administration of adiponectin and the use of its circulating levels as a diagnostic biomarker are further discussed based on the latest experimental studies.
