Degmacyte

103:, oxidative drugs and unstable hemoglobins. People receiving large quantities of oxidative drugs such as dapsone or sulfasalazine are more prone to have degmacytes. The underlying cause of degmacytes is a result of the splenic macrophages removing Heinz bodies from the membrane of red blood cells, which results in a "bitten" appearance of the cell. 59: 66:
Degmacytes usually appear smaller, denser, and more contracted than a normal red blood cell due to the bites. The appearance of the "bites" in red blood cells may vary in number, smoothness, and size. These cells can also exhibit other peripheral effects.

to analyze the red blood cells in the blood. The degmacyte look similar to a "bitten apple", which is their defining feature. However, bite cells may be difficult to distinguish from

As there are currently no means of reversing red blood cell damage and the formation of degmacytes, treatment options are limited to

Bite cells are caused by G6PD deficiency, NADPH deficiency, thalassemia, glutathione synthase deficiency, and other red-cell
