What is a common cause for elevation of pseudcholinesterase in the serum?

The elevation of pseudcholinesterase in the serum is commonly associated with exposure to organophosphate insecticides. These chemicals inhibit the activity of acetylcholinesterase, which plays a critical role in breaking down the neurotransmitter acetylcholine at neuromuscular junctions. Pseudcholinesterase is an enzyme that also hydrolyzes acetylcholine, and when organophosphates inhibit acetylcholinesterase, the body compensates by increasing the production of pseudcholinesterase, leading to elevated serum levels.

In contrast, while viral infections, liver cirrhosis, and hypothyroidism may affect various biochemical markers in the body, they do not specifically lead to a rise in pseudcholinesterase levels in the same way that organophosphate exposure does. For instance, liver cirrhosis can actually cause a decrease in pseudcholinesterase levels because the liver is responsible for producing this enzyme, and its function can become impaired in liver disease. Similarly, viral infections and hypothyroidism have different metabolic impacts and do not typically lead to increased pseudcholinesterase in the bloodstream. Thus, the relationship between organophosphate insecticides and pseudcholinesterase elevation is well established
