Penicillin-induced haemolytic anaemia associated with microangiopathy
Australian and New Zealand Journal of Medicine
|April 1, 1976
Abstract:
The development of a penicillin-induced haemolytic anaemia was studied in a patient with microangiopathy following an average daily dose of five million units of penicillin G (total dose 46 million units). It has been proposed that the combination of the benzylpenicilloyl hapten with exposed or altered erythrocyte antigens, induces an autoimmune response. In this particular case, it is suggested that erythrocyte membrane damage has predisposed to immune drug-mediated red cell damage.
Insights
Penicillin G can cause autoimmune hemolytic anemia in patients with microangiopathy. This occurs when the drug alters red blood cells, triggering an immune response and red cell damage.
Area of Science:
- Hematology
- Immunology
- Pharmacology
Background:
- Penicillin-induced hemolytic anemia is a rare but serious adverse drug reaction.
- Autoimmune mechanisms involving drug-hapten conjugates are implicated in its development.
- Microangiopathy may predispose individuals to drug-mediated erythrocyte damage.
