Is daily plasma exchange the best treatment for thrombotic thrombocytopenic purpura?
Mar 24, 2022 · Therapeutic plasma exchange (plasmapheresis) is used to treat acquired TTP. In this procedure, the liquid part of your blood (plasma) is replaced with donor plasma, using a machine that collects the cells in the blood. It removes antibodies (proteins) in your blood that damage your ADAMTS13 enzyme. Plasma exchange also replaces the ADAMTS13 enzyme.
How is idiopathic thrombocytopenic purpura (ITP) treated?
Thrombotic thrombocytopenic purpura (TTP), characterized by thrombocytopenia and microangiopathic haemolytic anaemia, was almost universally fatal until the introduction of plasma exchange (PE) therapy in the 1970s. Based on clinical studies, daily PE has become the first-choice therapy since 1991. Recent findings may explain its effectiveness ...

What is TTP in medical terms?
TTP is characterized by thrombotic microangiopathy (TMA), the formation of blood clots in small blood vessels throughout the body , which can lead to microangiopathic hemolytic anemia and thrombocytopenia. This characteristic is shared by two related syndromes, hemolytic-uremic syndrome (HUS) and atypical hemolytic uremic syndrome (aHUS). Consequently, differential diagnosis of these TMA-causing diseases is essential. In addition to TMA, one or more of the following symptoms may be present in each of these diseases: neurological symptoms (e.g. confusion, cerebral convulsions seizures, ); kidney impairment (e.g. elevated creatinine, decreased estimated glomerular filtration rate [eGFR], abnormal urinalysis ); and gastrointestinal (GI) symptoms (e.g. diarrhea nausea/vomiting, abdominal pain, gastroenteritis. Unlike HUS and aHUS, TTP is known to be caused by an acquired defect in the ADAMTS13 protein, so a lab test showing ≤5% of normal ADAMTS13 levels is indicative of TTP. ADAMTS13 levels above 5%, coupled with a positive test for shiga-toxin/enterohemorrhagic E. coli (EHEC), are more likely indicative of HUS, whereas absence of shiga-toxin/EHEC can confirm a diagnosis of aHUS.
What is a TTP?
Thrombotic thrombocytopenic purpura ( TTP) is a blood disorder that results in blood clots forming in small blood vessels throughout the body. This results in a low platelet count, low red blood cells due to their breakdown, and often kidney, heart, and brain dysfunction. Symptoms may include large bruises, fever, weakness, shortness of breath, ...

Predisposing factors are: 1 Cancer 2 Bone marrow transplantation 3 Pregnancy 4 Medication use:#N#Antiviral drugs ( acyclovir)#N#Certain chemotherapy medications such as gemcitabine and mitomycin C#N#Quinine#N#Oxymorphone#N#Quetiapine#N#Bevacizumab#N#Sunitinib#N#Platelet aggregation inhibitors ( ticlopidine, clopidogrel, and prasugrel)#N#Immunosuppressants ( ciclosporin, mitomycin, tacrolimus /FK506, interferon-α)#N#Hormone altering drugs (estrogens, contraceptives, hormone replacement therapy) 5 HIV-1 infection
Where does bruising occur?
The bruising often takes the form of purpura, while the most common site of bleeding, if it occurs, is from the nose or gums. Larger bruises ( ecchymoses) may also develop. The classic presentation of TTP, which occurs in less than 10% of people, includes five medical signs. These are:
What is the cause of TTP?
TTP of unknown cause was long known as idiopathic TTP but in 1998 the majority of cases were shown to be caused by the inhibition of the enzyme ADAMTS13 by antibodies. The relationship of reduced ADAMTS13 to the pathogenesis of TTP is known as the Furlan-Tsai hypothesis, after the two independent groups of researchers who published their research in the same issue of the New England Journal of Medicine. These cases are now classed as an autoimmune disease and are known as autoimmune TTP (not to be confused with immune/idiopathic thrombocytopenic purpura ).
What are the symptoms of a symtom?
Symptoms may include large bruises, fever, weakness, shortness of breath, confusion, and headache. Repeated episodes may occur. In about half of cases a trigger is identified, while in the remainder the cause remains unknown.
How do you know if you have TTP?
The signs and symptoms of TTP may at first be subtle and nonspecific. Many people experience an influenza-like or diarrheal illness before developing TTP. Neurological symptoms are very common and vary greatly in severity. Frequently reported symptoms include feeling very tired, confusion, and headaches. Seizures and symptoms similar to those of a stroke can also be seen. Other symptoms include, but are not limited to jaundice or paleness of the skin, a fast heart rate or shortness of breath, or pinpoint-sized purple or reddish dots on the skin known as petechiae.
Overview
Treatment
Due to the high mortality of untreated TTP, a presumptive diagnosis of TTP is made even when only microangiopathic hemolytic anemia and thrombocytopenia are seen, and therapy is started. Transfusion is contraindicated in thrombotic TTP, as it fuels the coagulopathy. Since the early 1990s, plasmapheresis has become the treatment of choice for TTP. This is an exchange transfusion involving removal of the person's blood plasma through apheresisand replacement wit…

Causes
TTP, as with other microangiopathic hemolytic anemias (MAHAs), is caused by spontaneous aggregation of platelets and activation of coagulation in the small blood vessels. Platelets are consumed in the aggregation process and bind vWF. These platelet-vWF complexes form small blood clots which circulate in the blood vessels and cause shearing of red blood cells, resulting in their ruptureand …
Pathophysiology
The underlying mechanism typically involves autoantibody-mediated inhibition of the enzyme ADAMTS13, a metalloprotease responsible for cleaving large multimers of von Willebrand factor (vWF) into smaller units. The increase in circulating multimers of vWF increases platelet adhesion to areas of endothelial injury, particularly where arterioles and capillariesmeet, which in turn results in the formation of small platelet clots called thrombi. As platelets are used up in the formation …

Prognosis
The mortality rate is around 95% for untreated cases, but the prognosis is reasonably favorable (80–90% survival) for people with idiopathic TTP diagnosed and treated early with plasmapheresis.
Epidemiology
The incidence of TTP is about 4–5 cases per million people per year. Idiopathic TTP occurs more often in women and people of African descent, and TTP secondary to autoimmune disorders such as systemic lupus erythematosusoccurs more frequently in people of African descent, although other secondary forms do not show this distribution. Pregnant women and women in the post partum period accounted for a notable portion (12–31%) of the cases in some studies; TTP affe…
