Summary
Plasma hyaluronan levels are significantly elevated in women with severe pre-eclampsia and eclampsia. This finding suggests hyaluronan may play a role in pre-eclampsia pathogenesis, though the exact cause remains unknown.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Biochemistry
Background:
- Pre-eclampsia is a severe pregnancy disorder characterized by endothelial dysfunction and potential hepatic impairment.
- Current diagnostic methods for pre-eclampsia lack early specificity and reliable monitoring capabilities.
- Hyaluronan, an extracellular matrix component, is normally cleared by the liver, and elevated levels indicate hepatic dysfunction.
Purpose of the Study:
- To investigate plasma hyaluronan concentrations in pregnant women with severe pre-eclampsia or eclampsia.
- To assess the potential of hyaluronan as a biomarker for pre-eclampsia and eclampsia.
Main Methods:
- Plasma hyaluronan levels were measured in 11 women with severe pre-eclampsia/eclampsia.
- Control groups included 31 healthy pregnant women (18 vaginal delivery, 13 caesarean section).
- Measurements were taken before and after delivery.
Main Results:
- Significantly higher plasma hyaluronan concentrations were observed in the pre-eclampsia/eclampsia group both before and after delivery compared to controls.
- Pre-eclampsia group: 171 microg/L (pre-delivery) and 215 microg/L (post-delivery).
- Control groups (caesarean/vaginal delivery): 13/28 microg/L and 12/30 microg/L respectively. A minor post-delivery increase was noted in controls.
Conclusions:
- Plasma hyaluronan is markedly increased in severe pre-eclampsia and eclampsia.
- The underlying mechanism for elevated hyaluronan in these conditions requires further investigation.
- Hyaluronan warrants further study as a potential biomarker in pre-eclampsia.

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:21Hyperosmolar Hyperglycemic State
Hyperosmolar Hyperglycemic State, or HHS, is a serious and life-threatening complication of type 2 diabetes mellitus. It is characterized by three main features: severe hyperglycemia, profound dehydration, and elevated serum osmolality, all occurring without significant ketoacidosis.HHS typically develops in older adults or individuals with limited access to fluids. This may result from illness, cognitive impairment, or medications such as diuretics or corticosteroids. These factors reduce...
01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
01:19Cerebral Edema l: Introduction
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:19Ascites
DefinitionAscites is the buildup of fluid inside the peritoneal cavity. It occurs when fluid moves out of the vascular system faster than the peritoneal lymphatics can remove it. This fluid shift is most commonly seen in liver cirrhosis but can also appear in several other systemic disorders.EtiologyCirrhosis remains the leading cause of ascites. Other conditions that can contribute include:Heart failureConstrictive pericarditisAbdominal cancersNephrotic syndromeSevere protein–calorie...
