What medications cause TTP?
In this review, five drugs that have been the subject of the most and the most recent reports of drug-associated TTP-HUS are discussed: mitomycin C, cyclosporine, quinine, ticlopidine, and clopidogrel.
What triggers TTP?
What causes TTP? Causes and risk factors. TTP occurs when you do not have the right amount of an enzyme (a type of protein in your blood) called ADAMTS13. This enzyme controls how your blood clots. If you do not have enough ADAMTS13, your body makes too many blood clots.
Which class of anti platelet drugs may cause TTP as an adverse effect?
The use of antiplatelet agents such as the thienopyridine derivates like Clopidogrel and ticlopidine, is known to be associated with drug induced TTP. TTP is a rare complication of thienopyridine treatment.
Can antibiotics cause TTP?
Antibiotics are not a common cause of drug- induced TTP. Some case reports of antibiotic- induced TTP implicated ciprofloxacin, clarithromycin, cephalosporins, piperacillin, rifampin, sulfonamides, penicillin, ampicillin, or valacyclovir therapy as a culprit.
How do you acquire TTP?
Acquired TTP is caused when a person's body mistakingly makes antibodies that block the activity of the ADAMTS13 enzyme. THe ADAMTS13 enzyme normally helps control the activity of certain blood clotting factors.
What should be avoided during TTP?
Do not drink or eat anything that contains quinine. Quinine can make TTP worse. Quinine is found in tonic water, flavored drinks, and some foods. Read all food and drink labels to check for quinine.
What medications can affect platelet function?
Drugs. Aspirin, other NSAIDs, inhibitors of the platelet P2Y12 adenosine diphosphate (ADP) receptor (eg, clopidogrel, prasugrel, ticagrelor), and glycoprotein IIb/IIIa receptor inhibitors (eg, abciximab, eptifibatide, tirofiban) may induce platelet dysfunction.
What medications decrease platelets?
Certain medications can reduce the number of platelets in your blood. Sometimes a drug confuses the immune system and causes it to destroy platelets. Examples include heparin, quinine, sulfa-containing antibiotics and anticonvulsants.
Can ibuprofen cause low platelets?
Over-the-counter pain medications, such as aspirin and ibuprofen (Advil, Motrin IB, others) can prevent platelets from working properly.
How low can platelets go before death?
When the platelet count drops below 20,000, the patient may have spontaneous bleeding that may result in death.
What causes a drop in platelets?
A low platelet count can be a result of the body destroying too many platelets too quickly. Some reasons a body might destroy its platelets include : side effects of certain medications, including diuretics, some antibiotics, blood thinners, and anti-seizure medications. an enlarged spleen.
Does Covid affect platelet count?
In COVID-19 patients, platelet count differs between mild and serious infections. Patients with mild symptoms have a slightly increased platelet count, whereas thrombocytopenia is a hallmark of severe COVID-19 infections.
Is TTP an autoimmune disease?
This form or TTP is considered to be an autoimmune disease and is caused when patients develop an antibody against the ADAMTS13 protease leading to low levels of the protease. If the disorder is present at birth (familial form), signs and symptoms may typically appear earlier, in infancy or early childhood.
Can you live a long life with TTP?
Thrombotic thrombocytopenic purpura is a serious condition that must be treated immediately. Be sure to call your healthcare provider or visit your local emergency room if you develop troublesome symptoms, including purplish spots on your skin. With proper treatment, most people with TTP can lead normal lives.
When should you suspect TTP?
TTP should be suspected in all patients with MAHA and thrombocytopenia unless an obvious alternative etiology is present. Although MAHA and thrombocytopenia are the hallmarks of TTP,2,3 end-organ involvement and its severity are extremely variable.
What are the signs and symptoms of TTP?
SymptomsBleeding into the skin or mucus membranes.Confusion.Fatigue, weakness.Fever.Headache.Pale skin color or yellowish skin color.Shortness of breath.Fast heart rate (over 100 beats per minute)
