Elevated levels of the alkaline phosphatase enzyme are reported among those who have obesity. A study reported there were higher serum levels of alkaline phosphatase in obese than in the non-obese. With elevated alkaline phosphatase levels, there is an increase in disproportionate intracellular fat depots and thereby releasing itself into the ...
All people with ALPS have signs of lymphoproliferation, which makes it the most common clinical manifestation of the disease. The increased proliferation of lymphoid cells can cause the size of lymphoid organs such as the lymph nodes and spleen to increase (lymphadenopathy and splenomegaly, present in respectively over 90% and over 80% of patients).
Muscle sources of the enzymes, such as intense exercise, are unrelated to liver function and can markedly increase AST and ALT. [5] Cirrhosis of the liver or fulminant liver failure secondary to hepatitis commonly reach values for both ALT and AST in the >1000 U/L range; however, many people with liver disease have normal transaminases.
The proportion of AST to ALT in hepatocytes is about 2.5:1, but because AST is removed from serum by the liver sinusoidal cells twice as quickly (serum half-life t 1/2 = 18 hr) compared to ALT (t 1/2 = 36 hr), so the resulting serum levels of AST and ALT are about equal in healthy individuals, resulting in a normal AST/ALT ratio around 1.
Autoimmune hepatitis, formerly known as lupoid hepatitis, plasma cell hepatitis, or autoimmune chronic active hepatitis, is a chronic, autoimmune disease of the liver that occurs when the body's immune system attacks liver cells, causing the liver to be inflamed.
The enzyme alkaline phosphatase (ALP, alkaline phenyl phosphatase, also abbreviated PhoA) is a phosphatase with the physiological role of dephosphorylating compounds. The enzyme is found across a multitude of organisms, prokaryotes and eukaryotes alike, with the same general function, but in different structural forms suitable to the environment they function in. Alkaline phosphatase is found ...
Hepatitis E is inflammation of the liver caused by infection with the hepatitis E virus (HEV); [4] [5] it is a type of viral hepatitis. [6] Hepatitis E has mainly a fecal-oral transmission route that is similar to hepatitis A , although the viruses are unrelated.
Rarely, people with the hepatitis A virus can rapidly develop liver failure, termed fulminant hepatic failure, especially the elderly and those who had a pre-existing liver disease, especially hepatitis C. [17] [81] Mortality risk factors include greater age and chronic hepatitis C. [17] In these cases, more aggressive supportive therapy and ...
