The aim of this study was to investigate the expression of glycodelin A (formerly named PP14) in decidual tissue of placentas with intrauterine growth restriction (IUGR), preeclamptic patients, hemolysis, elevated liver, low-platelet (HELLP) patients and normal decidual tissue.
The BclI, N363S, and ER22/23EK polymorphisms of the GR gene were determined in 300 healthy pregnant women, 150 pregnant women with severe preeclampsia including 17 pregnant women with HELLP syndrome.
The presence of at least one polymorphic allele for NOS3T-786C was also associated with the occurrence of eclampsia or HELLP syndrome among preeclamptic women.
We observed an association of common TLR4 and NOD2 gene variants, and pro-inflammatory phenotype with a history of early-onset preeclampsia and HELLP syndrome.

As hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome is one of the most severe forms of pre-eclampsia we aimed to assess the prevalence of the factor V Leiden, the prothrombin 20210G >A mutation and the methylenetetrahydrofolate reductase (MTHFR) 677C >T polymorphism in women with HELLP syndrome and in their fetuses from the same index pregnancy.
MBL-54 heterozygosity was more frequent in controls (27.2%) than in pre-eclamptic women (4.5%, P = 0.025) and those with HELLP syndrome (11.7%, P = 0.05) who delivered an IUGR neonate.

The activation of ERK1/2 signaling may induce additional trophoblastic functional changes in HELLP syndrome, while distinct mechanisms may promote late-onset preeclampsia.
The placental expression of MAPK p38alpha was investigated by semiquantitative polymerase chain reaction using cDNA extracted from placental tissue of 15 pregnancies with HELLP syndrome and 15 gestational age-matched controls.
In pregnancy it usually affects women with HELLP syndrome or acute fatty liver of pregnancy and results from the reduced hepatic degradation of placental vasopressinase leading to its increased activity.
In conclusion, parallel to its decreased placental expression, an augmented membrane shedding of PP13 contributes to the increased third trimester maternal serum PP13 concentrations in women with preterm pre-eclampsia and HELLP syndrome.
We decided to study four leptin receptor (LEPR) SNP polymorphisms in HELLP syndrome patients by using quantitative real-time PCR and melting curve analysis.
Several studies have shown overexpression of leptin in microarray experiments in pre-eclampsia (PE) and in hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome.
Our aim was to compare the tetranucleotide repeat (TTTC)(n) polymorphism in the 3'-flanking region in the LEP gene on DNA samples from patients with pre-eclampsia (PE), hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome and healthy pregnant controls.
We found that: 1) Placental LEP and FLT1 expression was up-regulated in preterm preeclampsia with or without HELLP syndrome compared to controls; 2) Mean pp38 immunoscore was higher in preterm preeclampsia, especially in cases with HELLP syndrome, than in controls.
None of the IL1B and IL1RN polymorphisms provided evidence for either association or linkage with the risk for (pre)eclampsia/HELLP syndrome, preeclampsia only or HELLP syndrome only.

Enrichment analyses revealed similar biological processes, cellular compartments and biological pathways enriched in early-onset preeclampsia and HELLP syndrome; however, some processes and pathways (e.g., cytokine-cytokine receptor interaction) were over-represented only in HELLP syndrome.
Women with features of HELLP displayed the highest plasma proteasome levels and activity, which correlated with decreased IFN-γ (interferon-γ), and increased IL (interleukin)-8 and IL-10.
