Use an electric razor, and be cautious when using nail trimmers, knives, etc. La raison en est que dans le cas du PTI, les plaquettes circulantes sont, par définition, très jeunes (puisque leur durée de vie est très raccourcie), or les fonctions plaquettaires sont d'autant plus actives que les plaquettes sont jeunes.

Une épreuve isotopique, après marquage des plaquettes du patient par un isotope radioactif, permet de préciser la durée de vie des plaquettes (très diminuée en cas de PTI), le siège de destruction préférentiel des plaquettes (rate, rate+foie, ou vasculaire/diffus), et aussi le degré de production des plaquettes par la moelle osseuse (typiquement augmentée en cas de PTI). Une antibiothérapie par oracilline ou amoxicilline pendant les deux années qui suivent la splénectomie est préconisée chez l'adulte ; elle est souvent plus longue chez l'enfant. Idiopathic thrombocytopenic purpura (ITP), also called immune thrombocytopenic purpura, is a condition in which the body does not have enough platelets.

Idiopathic thrombocytopenic purpura: Cases of immune thrombocytopenic purpura whose cause is still unknown. Idiopathic Thrombocytopenic Purpura. The platelet plug then binds certain proteins in the blood to form a clot that stops bleeding. Idiopathic thrombocytopenic purpura (ITP) is a rare autoimmune disorder, in which a person's blood doesn't clot properly, because the immune system destroys the blood-clotting platelets. Idiopathic thrombocytopenic purpura (ITP) is a condition characterised by idiopathic (spontaneous) thrombocytopenia (low platelet count) causing a purpuric rash (non-blanching rash).
