Hyperviscosity syndrome is a group of symptoms triggered by an increase in the viscosity of the blood. Symptoms of high blood viscosity include spontaneous bleeding from mucous membranes , visual disturbances due to retinopathy , and neurologic symptoms ranging from headache and vertigo to seizures and coma .
a) increasing blood viscosity thereby reducing blood flow to tissues to cause hyperviscosity syndrome (i.e., headache, confusion, blurry or loss of vision, hearing loss, and epistaxis (nose bleeds); b) depositing in small arteries and capillaries, thereby plugging these blood vessels and causing infarction and necrosis of tissues including in ...
In contrast, type I cryoglobulinemia causes damage solely due to hyperviscosity syndrome, which refers to the aggregation and resulting obstructing nature of cryoglobulins in blood vessels resulting in reduced perfusion of tissues and possibly necrosis if prolonged. Therefore, vasculitis generally occurs only in patients affected by mixed (type ...
[4] [5] SCLS is thus a limb- and life-threatening illness, because each episode has the potential to cause damage to limb muscles and nerves, as well as to vital organs due to limited perfusion. [4] [5] It is often misdiagnosed as polycythemia, polycythemia vera, hyperviscosity syndrome, or sepsis. [4]
Cryoglobulinemia - Antibodies that are sensitive to the cold can become activated in cold conditions and cause an increase in blood viscosity (hyperviscosity syndrome) as well as forming immune complexes that can deposit in the small blood vessels and can cause nephritic syndrome when this occurs in the kidneys. [26]
Most people know that GLP-1 receptor agonist medications like Ozempic and Wegovy can cause relatively minor side effects like nausea and diarrhea. But new research confirms that more serious ...
Diabetes can cause many health issues, including sexual health challenges like erectile dysfunction (ED). Besides type 2 diabetes management, metformin has been shown to help non-diabetic people ...
On the whole, flu A viruses tend to cause a more intense illness, Dr. Russo says. “Both flu A and flu B can be lethal, but flu A tends to cause more severe disease,” he says. Another major ...
