Hemoglobinuria is a condition in which the oxygen transport protein hemoglobin is found in abnormally high concentrations in the urine. [1] The condition is caused by excessive intravascular hemolysis, in which large numbers of red blood cells (RBCs) are destroyed, thereby releasing free hemoglobin into the plasma. [2]
Hematuria can be classified according to visibility, anatomical origin, and timing of blood during urination. [1] [6]In terms of visibility, hematuria can be visible to the naked eye (termed "gross hematuria") and may appear red or brown (sometimes referred to as tea-colored), or it can be microscopic (i.e. not visible but detected with a microscope or laboratory test).
Kidney ischemia [1] is a disease with a high morbidity and mortality rate. [2] Blood vessels shrink and undergo apoptosis which results in poor blood flow in the kidneys. More complications happen when failure of the kidney functions result in toxicity in various parts of the body which may cause septic shock, hypovolemia, and a need for surgery. [3]
As in the related condition TTP, reduced blood flow through the narrowed blood vessels of the microvasculature leads to reduced blood flow to vital organs, and ischemia may develop. [11] The kidneys and the central nervous system (brain and spinal cord) are the parts of the body most critically dependent on high blood flow, and are thus the ...
This condition is caused by the deceased liver's decreased ability to esterificate cholesterol. [61] Thalassemia: D56: D013789 Thalassaemia is an inherited blood disorder which is caused by genetic mutations that causes the body to make fewer healthy red blood cells and less hemoglobin due to lack of protein chains. Triosephosphate isomerase ...
Heart-bypass surgery is an example of one such procedure. [citation needed] Drug overdoses, accidental or from chemical overloads of drugs such as antibiotics or chemotherapy, along with bee stings [25] may also cause the onset of acute kidney injury. Unlike chronic kidney disease, however, the kidneys can often recover from acute kidney injury ...
This can shift the ratio of red blood cells towards younger, larger cells. This shift may be reflected in higher than normal mean corpuscular volume (MCV) values, an indicator of red blood cell size. [4] This is not a pathological condition but may indicate a propensity toward iron deficiency anemia due to high red blood cell turnover.
Stress ulceration is a single or multiple fundic mucosal ulcers that causes upper gastrointestinal bleeding, and develops during the severe physiologic stress of serious illness. It can also cause mucosal erosions and superficial hemorrhages in patients who are critically ill, or in those who are under extreme physiologic stress, causing blood ...
