Uremia is the condition of having high levels of urea in the blood. Urea is one of the primary components of urine.It can be defined as an excess in the blood of amino acid and protein metabolism end products, such as urea and creatinine, which would normally be excreted in the urine.
Atypical hemolytic uremic syndrome (aHUS), also known as complement-mediated hemolytic uremic syndrome (not to be confused with hemolytic–uremic syndrome), is an extremely rare, life-threatening, progressive disease that frequently has a genetic component. In most cases, it can be effectively controlled by interruption of the complement cascade.
Children are more commonly affected, but most children recover without permanent damage to their health, although some children may have serious and sometimes life-threatening complications. [6] Adults, especially the elderly, may show a more complicated presentation. [2] [6] Complications may include neurological problems and heart failure. [1]
In diseases such as hemolytic uremic syndrome, disseminated intravascular coagulation, thrombotic thrombocytopenic purpura, and malignant hypertension, the endothelial layer of small vessels is damaged with resulting fibrin deposition and platelet aggregation. As red blood cells travel through these damaged vessels, they are fragmented ...
Hemolytic-uremic syndrome: D59.3: 13052: Hemolytic-uremic syndrome (HUS) (also known as haemolytic-uraemic syndrome) is a disease characterized by hemolytic anemia, acute renal failure and a low platelet count (thrombocytopenia). It predominantly but not exclusively affects children.
[8] [9] If the condition is allowed to progress without treatment, it can eventually lead to azotemia and uremic symptoms. [9] This constellation of symptoms contrasts with the classical presentation of nephrotic syndrome (excessive proteinuria >3.5 g/day, low plasma albumin levels (hypoalbuminemia) <3 g/L, generalized edema, and hyperlipidemia ...
The prognosis for nephrotic syndrome under treatment is generally good although this depends on the underlying cause, the age of the person and their response to treatment. It is usually good in children, because minimal change disease responds very well to steroids and does not cause chronic kidney failure.
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).
