Unauthorized use of these marks is strictly prohibited. They may be associated with central nervous system irritation or be an indication of swelling of the brain (cerebral edema).

HELLP (i.e., hemolysis, elevated liver enzymes, and low platelet count) syndrome is a form of severe preeclampsia with high rates of neonatal and maternal morbidity.
