**6.3 Severe preeclampsia**

Severe preeclampsia is defined as a systolic BP ≥160 mm Hg and/or a diastolic BP ≥110 mm Hg, if detected on two separate occasions, with a 6-hour difference, with proteinuria greater than 5 g/24 hours and no previous history of arterial hypertension, diabetic nephropathy, or renal disease.

HELLP syndrome is the acronym of hemolysis, elevated liver enzyme levels, and low platelet levels; this syndrome occurs in 10–20% of women with preeclampsia or eclampsia and is considered a severe form of the disease since it leads to increased mortality.
