Microangiopathic hemolytic anemia (MAHA) is a microangiopathic subgroup of hemolytic anemia (loss of red blood cells through destruction) caused by factors in the small blood vessels. It is identified by the finding of anemia and schistocytes on microscopy of the blood film .
Schistocytes on the peripheral blood smear is a characteristic feature of microangiopathic hemolytic anemia (MAHA). [5] The causes of MAHA can be disseminated intravascular coagulation, thrombotic thrombocytopenic purpura, hemolytic-uremic syndrome, HELLP syndrome, malfunctioning cardiac valves etc. In most of the conditions, schistocytes are ...
Hemolytic anemia accounts for 5% of all existing anemias. [2] It has numerous possible consequences, ranging from general symptoms to life-threatening systemic effects. [2] The general classification of hemolytic anemia is either intrinsic or extrinsic. [3] Treatment depends on the type and cause of the hemolytic anemia. [2]
Bacterial toxins are the primary cause of one category of thrombotic microangiopathy known as HUS or hemolytic uremic syndrome. HUS can be divided into two main categories: Shiga-toxin-associated HUS (STx-HUS), which normally presents with diarrhea, and atypical HUS. The Shiga-toxin inhibits the binding of eEF-1-dependent binding of aminoacyl ...
TTP is a form of thrombotic microangiopathy (TMA), [37] the formation of blood clots in small blood vessels throughout the body, which can lead to microangiopathic hemolytic anemia and thrombocytopenia. [37] This characteristic is shared by two related syndromes, hemolytic-uremic syndrome (HUS) and atypical hemolytic uremic syndrome (aHUS). [4]
Diabetic microangiopathy, which is the most common cause of microangiopathy, is more prevalent in the kidney, retina and vascular endothelium since glucose transport in these sites isn’t regulated by insulin and these tissues cannot stop glucose from entering cells when blood sugar levels are high. [16]
Other causes can include acid reflux, asthma, allergies, or other chronic medical conditions, adds Richard Watkins, M.D., an infectious disease physician and professor of medicine at the Northeast ...
