Platelets (20-30) x 10^9/L and how long one can live depends on the cause of the platelet drop. Immune thrombocytopenic purpura, as well as thrombotic thrombocytopenic purpura, have a better prognosis and do not affect life expectancy in some patients. If the platelet drop is caused by aplastic anemia, acute leukemia, etc., the prognosis is worse.
1. immune thrombocytopenic purpura: manifested as spontaneous skin and mucous membrane bleeding, pinpoint size, more distribution of limbs, bleeding asymmetry, often accompanied by nasal and gum bleeding. 80% ~ 90% of patients healed within six months of the onset of the disease, so the prognosis is better, and generally does not affect life expectancy.
2. Thrombotic thrombocytopenic purpura: manifested as generalized skin bleeding spots or petechiae. About 20%~50% of the patients can recur, and the recurrence time is about one year after the remission, but the original treatment program is still effective after the recurrence. Therefore, as long as the treatment is maintained, the prognosis is still good. For example, plasma replacement.
3. Aplastic anemia: manifested by severe anemia, infection and bleeding tendency, the mortality rate of severe aplastic anemia is very high, with the progress of medical level in recent years, the prognosis has been improved, but there are still about 1/3 of aplastic anemia patients died of infection and bleeding.
4. Malignant blood diseases: such as acute leukemia, non-Hodgkin’s lymphoma, can lead to thrombocytopenia, survival time is related to the specific type of disease and the effect of treatment, such as acute myeloid leukemia need to be given to cytarabine and other drugs such as chemotherapy.
Thrombocytopenia can also be caused by other diseases, such as severe liver disease. It is recommended to seek medical advice as soon as possible to identify the cause of thrombocytopenia and treat the cause under the guidance of a physician.
