Arsenic produces cellular damage through a variety of mechanisms. Arsenic binds to enzyme sulfhydryl groups and forms a stable ring, which deactivates the enzyme. The process of deactivating the enzyme causes widespread endothelial cell damage, vasodilation, and leakage of plasma. Massive transudation of fluid into the bowel lumen, mucosal vesicle formation, and tissue sloughing may result in large gastrointestinal fluid losses. Arsenic binds to dihydrolipoic acid, a pyruvate dehydrogenase cofactor, blocking the conversion of pyruvate to acetyl coenzyme A and inhibiting gluconeogenesis. Arsenic competes with phosphates for adenosine triphosphate, forming adenosine diphosphate monoarsine, causing the loss of high-energy bonds.
In some forms, arsenic is caustic, exerting a direct toxic effect on blood vessels and large organs. Long-term exposure results in nerve damage and may lead to lung, skin, or liver cancer. Once inhaled, arsine gas combines with hemoglobin in RBCs, causing severe hemolysis and anemia. Patients develop hemoglobinuria and hematuria within several hours of exposure.
