“…Macroamylasamia is characterized by hyperamylasemia or elevated serum amylase levels without elevated urine amylase and other clinical signs or symptoms. In macroamylasmia, amylase is most often bound by immunoglobulin, making it 4 times larger than usual and the kidneys excrete it slowly and with difficulty, resulting in high serum amylase levels but normal urine levels [7][8][9][10][11][12]. In most cases, macromolecular amylase is a complex of normal amylase and immunoglobulin A or G. Different papers report different statistics on the incidence of macroamylasemia.…”

“…Macroamylasemia was rst described by Wilding in 1964. (3,4) Macroamylasemia should be suspected in a patient with a high serum alpha-amylase level without an elevation in the urine alpha-amylase level. Serum amylase proteins bind with other serum proteins like immunoglobulins A( 92%), immunoglobulins G (<30%), and others (<5%), forming macromolecular complexes that weigh more than 400 KDa.…”

“…Макроамилаземия -редкое, доброкачественное состояние, характеризующееся повышенным уровнем амилазы в крови при нормальном уровне амилазы в моче и отсутствием каких-либо клинических проявлений [2,10,12,14]. Этиология этого состояния недостаточно изучена.…”

“…Этиология этого состояния недостаточно изучена. При макроамилаземии амилаза связывается с иммуноглобулинами плазмы, что увеличивает ее молекулярную массу и препятствует экскреции ее почками [2,10,12,14]. По данным J.E.…”
