Hyperviscosity of the newborn is the slowing and blockage of blood flow that results when there are too many red blood cells in an infant's blood.
Overview, Causes, & Risk Factors ...
Hyperviscosity
This means that the blood may become too thick due to a very high level of paraprotein.
Hyperviscosity - newborn
Vision problems
Macroglobulinemia of Waldenstrom is a cancer of the B lymphocytes (a type of white blood cell). It is associated with the overproduction of proteins called IgM antibodies.
Hyperviscosity (increased blood thickness), which can cause a red complexion (plethora), headaches, visual disturbance, tiredness, breathlessness and bleeding.
Gout (in 10 to 15 per cent of patients).
Itching.
Weight loss.
Fatigue.
Sweating.
Hyperviscosity syndrome, which occurs when the protein concentration in the blood becomes very high and the blood becomes very thick and sticky. Signs and symptoms of hyperviscosity are shortness of breath, confusion, and chest pain.
Hyperviscosity syndrome (thickening of blood): signs include shortness of breath, confusion, or chest pain.
Cryoglobulinemia: signs include pain and numbness in extremities in cold weather.
Hyperviscosity caused by hypovolemia
Protein undernutrition in children (sometimes with brittle hair and nails, alopecia, and stunted growth)
Loss of proteins ...
Hyperviscosity syndrome: Symptoms associated with sludging in the blood vessels may include spontaneous bruising or bleeding (from the mouth, nose, or internally), visual problems (due to bleeding and vascular problems in the eye [retinopathy]), ...
Symptoms of hyperviscosity (thick blood)
IgM proteins are large molecules, and when they accumulate in the blood in high levels, the blood can become viscous or thick, thereby slowing down the flow of blood to different parts of the body.
Waldenström macroglobulinemia has a natural history and therapeutic options similar to CLL, with the exception of hyperviscosity syndrome associated with macroglobulinemia as a result of elevated immunoglobulin M.
Patients with pronounced hyperviscosity usually receive chemotherapy (anticancer drugs). A type of treatment called plasmapheresis may be performed to relieve symptoms such as excessive bleeding and dizziness.
The primary concern with polycythemia relates to hyperviscosity (thick blood, which slows down blood flow) and its associated complications. Polycythemia occurs in 0.4-12% of neonates (U.S. figures).
This overproduction results in increased volume of the blood (hypervolemia) and thickening of the blood (hyperviscosity), both of which impair its usual rapid flow through the blood vessels to the brain, heart, gastrointestinal tract, ...
[31,32,33,34,35,36] If the viscosity relative to water is greater than four, the patient may have manifestations of hyperviscosity.
Headache, visual changes and retinopathy may be the result of hyperviscosity of the blood depending on the properties of the paraprotein.
It is characterised by overproduction of IgM, which causes the blood to become too thick (hyperviscosity). This hyperviscosity interferes with blood flow through small blood vessels, which leads to many of the symptoms of the disease.
Thickening of the blood - Thickening of the blood (called hyperviscosity syndrome) rarely occurs in individuals with multiple myeloma.
Definition Waldenstrom's macroglobulinemia is a rare, chronic cancer of the immune system that is characterized by hyperviscosity, or thickening, of the blood.
Congestive heart failure
Hyperviscosity
Hypofibrinogenemia (decreased fibrinogen levels)
Low plasma protein (due to liver or kidney disease)
Polycythemia
Sickle cell anemia ...
Anemia (too few red blood cells)
Polycythemia (too many red blood cells)
Hyperviscosity (abnormal thickening of the blood)
Vasculitis or blood vessel inflammation
Endocarditis (infection of the lining of the heart)
Various blood clotting disorders ...
Consequently, the blood thickens and increases in volume, a condition called hyperviscosity. Thickened blood may not flow through smaller blood vessels properly.
Overproduction of IgM causes the blood to become too thick. This is called hyperviscosity. It occasionally makes it harder for blood to flow through small blood vessels.
Hyperviscosity. With this condition, a mixture of hemoglobin S and normal hemoglobin causes the blood to become sticky. The patient is at risk for high blood pressure, altered mental status, and seizures. Careful monitoring can prevent this condition.
If secondary polycythemia has produced hazardous hyperviscosity, or if the patient doesn't respond to treatment for the primary disease, reduction of blood volume by phlebotomy or pheresis may be effective.
Phlebotomy (removal of blood) may be recommended when erythrocytosis causes hyperviscosity (extreme thickness) of the blood. The volume of the blood removed is replaced with intravenous (IV) saline solution to thin the blood.
Phlebotomy (removal of blood) should not be done frequently, but may be recommended when erythrocytosis causes hyperviscosity (extreme thickness) of the blood.
