The change in plasma concentration of human hepatocyte growth factor (hHGF) in pregnant women with HELLP (hemolysis, elevated liver enzyme and low platelets) syndrome was investigated, and the following results were obtained. (1) The plasma concentration of hHGF in pregnant women did not change with the gestational stage. (2) The plasma concentration of hHGF in pregnant women with EPH (edema, proteinuria and hypertension) gestosis was 0.19 +/- 0.07 ng/ml and did not differ greatly from that in control pregnant women. (3) The plasma concentration of hHGF in pregnant women with HELLP syndrome was 1.79 +/- 0.35 ng/ml; it was increased prominently compared to control pregnant women. (4) The plasma concentration of hHGF in pregnant women with HELLP syndrome changed parallel to the clinical symptoms of the syndrome.

The analysis covered 61 women with a history of EPH gestosis and 63 children born to them as well as 30 healthy women with normal arterial blood pressure during pregnancy and their 30 children aged 3-8 years. Hypertension exceeding 145/95 mm Hg was found in 26 mothers out of 61 at the moment of examination. In the other 35 patients from the EPH gestosis group arterial blood pressure was still within the norm, but diastolic blood pressure (DBP) values were significantly higher than in the control group. The values of DBP in children from mothers with EPH gestosis were higher than the values of DBP in children from the control group. However significantly higher values were observed only in children from mothers with constantly elevated blood pressure.

It was found that hyaluronic acid is the most abundant glycosaminoglycan (GAG) both in the umbilical cord arteries and in the umbilical cord veins. Chromatographic and as well as electrophoretic studies demonstrated that EPH-gestosis (Edema-Proteinuria-Hypertension), the most common pathological syndrome occurring in pregnancy, is accompanied by premature replacement of hyaluronic acid by sulphated GAGs in the investigated arteries but not in the veins. Such a replacement is a characteristic feature of the ageing process. One may conclude that EPH-gestosis is associated with a "premature ageing" of the umbilical cord arterial walls. The mechanism and possible role of this phenomenon in pathology are discussed.

Oedema, proteinuria, hypertension (EPH)-gestosis (pre-eclampsia) is associated with a premature replacement of hyaluronic acid by sulphated glycosaminoglycans (GAGs), both in the umbilical cord arteries and in Wharton's jelly. It may be concluded from our previous report that such a phenomenon may be the result of reduction in degradation of these compounds. In order to support such a conclusion the activities of GAG-degrading enzymes in normal umbilical cord arteries and those taken from newborns delivered by mothers with EPH-gestosis were compared. It was found that EPH-gestosis results in a significant reduction in the activities of neutral endoglycosidases degrading most of the sulphated GAGs (except keratan sulphate). In the case of acidic endoglycosidases, no characteristic alterations have been found. Only the activity of heparan sulphate-degrading endoglycosidase significantly decreased. In contrast to the above-mentioned endoglycosidases, the activities of arylsulphatase B and 6-sulphatase distinctly increased. The decrease in the activities of endoglycosidases are thought to be responsible for EPH-gestosis-associated accumulation of sulphated GAGs in extracellular matrix of Wharton's jelly. This leads to the suspicion that EPH-gestosis-induced changes in the GAGs composition may alter the fibrillogenesis conditions in Wharton's jelly. The sulphated GAGs accumulated in Wharton's jelly may interact with some growth factors which modify the myofibroblasts' proliferation, gene expression, protein biosynthesis and other processes. A significance of EPH-gestosis-induced alteration in Wharton's jelly is discussed.

HELLP syndrome belongs to the group of pathological states known as pregnancy-induced hypertension or EPH gestosis. The basic criteria for establishing the diagnosis are as follows: H for hemolysis, EL for elevated liver enzymes and LP for low platelets. A pregnant woman, 38 years of age, multipara (V pregnancy, third delivery) has been admitted to the Clinic of Gynecology and Obstetrics in Novi Sad in 36-37 week gestation complaining of nausea, vomiting, epigastric pain, general weakness, exhaustion as well as symptom of previously diagnosed preeclampsia. Due to signs of fetal distress, the patient has undergone urgent cesarean section, giving birth to a female premature newborn infant. Twenty-four hours after delivery all symptoms and signs HELLP syndrome manifested. Being in a critical state, the patient has been transferred to the Institute of Surgery, Clinic of Anesthesiology and Intensive Care with signs of multiple organ failure. With this case report of a patient with HELLP syndrome, we wished to point to importance of continual intensive clinical follow-up, laboratory monitoring and corresponding therapeutic procedures, and at the same time to this relatively rare syndrome.

Pregnancy in conjunction with primary aldosteronism is an unusual occurrence. We report a 28-year-old woman who presented with mild hypertension and hypokalemia as manifestations of primary aldosteronism caused by an aldosterone-producing adenoma in the left adrenal gland during pregnancy. Although the diagnosis was straightforward, the patient refused to undergo the proposed operation during the second trimester of her pregnancy. She was not admitted to hospital until she developed EPH gestosis in the 27th week of gestation, which had an unfavourable outcome for the infant who died nine days after delivery. The patient underwent a laparoscopic adrenalectomy which resulted in normalization of blood pressure and blood potassium levels. In cases of aldosterone-producing adenoma, surgery in the second trimester is the most appropriate option to avoid a poor obstetric outcome.

Pre-eclampsia--edema, proteinuria, hypertension (EPH-gestosis) is one of the more common complications observed during pregnancy. The umbilical cord vein walls were taken from newborns delivered by healthy mothers (control material) and by mothers with polysymptomatic pre-eclampsia (investigated material). Normal saphenous vein walls were collected from adult subjects undergoing varicose vein surgery. The collagen content was measured by the assay of hydroxyproline. Elastin was determined according to Fastin Elastin Assay and gravimetrically. Glycosaminoglycans content was determined by uronic acids assay. The collagen content decreased in the pre-eclampsia material. The amount of soluble elastin increased in the investigated material. The insoluble elastin content decreased in the umbilical cord veins of newborns delivered by mothers with pre-eclampsia. Reconstructing the umbilical cord vein wall may disturb fetal blood flow and affect the vascular system in adulthood.

Oedema/proteinuria/hypertension (EPH) gestosis is one of the more common complications observed during pregnancy. Our previous studies demonstrated some qualitative and quantitative changes in the extracellular matrix of Wharton's jelly in newborns delivered by mothers with EPH gestosis. For this reason it was decided to evaluate the effect of EPH gestosis on the activity of gelatinolytic and proteolytic enzymes which may be involved in collagen degradation in Wharton's jelly. Zymographic analysis of control and EPH gestosis samples of Wharton's jelly demonstrates different electrophoretic patterns of gelatinolytic enzymes. The control Wharton's jelly contains two latent forms of gelatinolytic enzymes: gelatinase A [metalloproteinase (MMP)-2, 72 kD] and gelatinase B (MMP-9, 92 kD). In contrast to control tissue, the main gelatinolytic enzyme of EPH gestosis Wharton's jelly is gelatinase A (MMP-2). It was found that the proteolytic activity in EPH gestosis Wharton's jelly differs from control. The decrease in gelatinase activity may be one of the factors which promote the accumulation of collagen in this tissue.

Edema, proteinuria, hypertension (EPH-gestosis), most commonly termed as pre-eclampsia, is the most common pregnancy-associated pathological syndrome. It is accompanied by a thorough remodelling of extracellular matrix in the umbilical cord tissues. It is commonly known that the presence of serum in culture medium strongly stimulates many functions of cells cultured in vitro. It was decided to check how the pre-eclamptic serum affects the fibroblast division in culture. Ki-67 is a protein present in proliferating cells and can be detected during all phases of the cell cycle (G1, S, G2/M) but not in resting (G0) cells. PCNA (proliferating cell nuclear antigen) is an intranuclear polypeptide whose synthesis rate is at its maximum during the S-phase of the cell cycle. The expression of Ki-67 and PCNA was measured by immunocytochemical methods and biosynthesis of DNA was evaluated by [14C]-thymidine incorporation. The activity of pre-eclamptic umbilical cord serum (UC-serum) was found to be distinctly lower in comparison to control one. The expression of Ki and PCNA in fibroblast cultures treated with pre-eclamptic serum was also distinctly lower. Also the incorporation of [14C]-thymidine to DNA was lower than in the cultures treated with control UC-serum. It may by concluded that pre-eclampsia reduces the mitogenic activity of the umbilical cord serum.

A comparative study of the morpho-functional characteristics of the circulating neutrophils was carried out by the electron microscopy method on women with physiological pregnancy and pregnancy-induced hypertension or EPH gestosis. Some leukocyte reactions were observed, and their intensity depended on the clinical manifestation of the EPH gestosis. In neutrophils there were detected reformation in the nucleus in the form of redistribution of the ratio between heterochromatin and euchromatin, as well as changes in the ultrastructure of nucleolemma. Both an amount of glycogen and initial or azurophil granules in the cytoplasm decreased very much but solubilization of their enzymes in cytosol did not occur. Such degranulation was due to the features of exocytosis which determined an extraleukocytic release of the content from the primary granules. The data obtained evidence that neutrophils are functionally active in the vascular bed and are likely to take part in the humoral regulation of the whole organism.
