HELLP syndrome is a complication of pregnancy; the acronym stands for hemolysis, elevated liver enzymes, and low platelet count. [1] It usually begins during the last three months of pregnancy or shortly after childbirth. [1]
Acute fatty liver of pregnancy is a rare life-threatening complication of pregnancy that occurs in the third trimester or the immediate period after delivery. [1] It is thought to be caused by a disordered metabolism of fatty acids by mitochondria in the fetus, caused by long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency. [2]
Gestational hypertension can develop after 20 weeks but has no other symptoms, and later rights itself, but it can develop into pre-eclampsia. [22] HELLP syndrome – Hemolytic anemia, elevated liver enzymes and a low platelet count. Incidence is reported as 0.5–0.9% of all pregnancies. [23]
Ischemic hepatitis, also known as shock liver, is a condition defined as an acute liver injury caused by insufficient blood flow (and consequently insufficient oxygen delivery) to the liver. [5] The decreased blood flow ( perfusion ) to the liver is usually due to shock or low blood pressure.
The enzymes that are defective in GS – UDP glucuronosyltransferase 1 family, polypeptide A1 (UGT1A1) – are also responsible for some of the liver's ability to detoxify certain drugs. For example, Gilbert syndrome is associated with severe diarrhea and neutropenia in patients who are treated with irinotecan , which is metabolized by UGT1A1.
The activation of HL occurs in two steps. First, HDL that makes its way to the liver, binds to HL thereby removing the heparan sulfate proteoglycan and freeing up the hepatic lipase into the bloodstream, but HL is still inactive due to the proteins on the surface of the lipoprotein. Second, HDL unbinds from HL to activate HL enzymes in the ...
As the disease progresses, it can cause life-threatening liver dysfunction or liver failure. [3] Infants are chronically ill from birth and rarely survive beyond the first year of life. In 2015, an enzyme replacement therapy, sebelipase alfa, was approved in the US and EU.
Hypoalbuminemia (or hypoalbuminaemia) is a medical sign in which the level of albumin in the blood is low. [1] This can be due to decreased production in the liver, increased loss in the gastrointestinal tract or kidneys, increased use in the body, or abnormal distribution between body compartments.
