Aplastic anaemia is a blood disorder in which the body's bone marrow doesn't make enough new blood cells. This may result in a number of health problems including arrhythmias, an enlarged heart, heart failure, infections and bleeding.
Aplastic anaemia is a rare but serious condition. It can develop suddenly or slowly and tends to worsen with time, unless the cause is found and treated.
A number of acquired diseases, conditions, and factors can cause aplastic anaemia including:
Toxins, such as pesticides, arsenic, and benzene；
Radiation and chemotherapy；
Medicines such as chloramphenicol；
Infectious diseases such as hepatitis, Epstein-Barr virus, cytomegalovirus, parvovirus B19, and HIV；
Autoimmune disorders such as lupus and rheumatoid arthritis；
Inherited conditions, such as Fanconi anaemia, Shwachman-Diamond syndrome, dyskeratosis congenital and Diamond-Blackfan anaemia may also cause aplastic anaemia.
