Thrombocytopenia can happen to anyone, although severe thrombocytopenia is considered to be rare among HIV-positive people. With the widespread use of anti-HIV drug treatment, it is likely that HIV-positive people taking these treatments are at a lower risk of developing thrombocytopenia.
Because most HIV-positive people ? whether or not they are taking anti-HIV drug treatment ? have their blood tested regularly for abnormalities like thrombocytopenia, it's possible to treat the thrombocytopenia before it can cause bleeding disorders.
