Insights
Breastfeeding does not prevent inhibitors in male infants with haemophilia A or B. This study found no protective effect of breastfeeding on inhibitor development in young boys with haemophilia.
Area of Science:
- Pediatric Hematology
- Immunology
- Epidemiology
Background:
- Inhibitors to factor VIII or IX can complicate haemophilia treatment.
- Oral immune tolerance is a potential mechanism to prevent inhibitor development.
Purpose of the Study:
- To investigate if breastfeeding reduces inhibitor development in male infants with haemophilia.
- To test the hypothesis that breastfeeding induces oral immune tolerance to factor VIII.
Main Methods:
- A structured epidemiological survey was conducted.
- Data included all male infants born with severe haemophilia A or B in Sweden between 1980 and 1999.
Main Results:
- The study included 100 males with haemophilia A (19 with inhibitors) and 16 with haemophilia B (6 with inhibitors).
- No statistically significant protective effect of breastfeeding on inhibitor development was observed.
Conclusions:
- Breastfeeding does not appear to reduce the risk of inhibitor development in male infants with haemophilia.
- Further research may be needed to explore other preventive strategies for inhibitor formation.
Abstract:
Our aim was to test the hypothesis that breastfeeding may reduce development of inhibitors in male infants with haemophilia by inducing an oral immune tolerance to factor VIII. To achieve that goal, we performed a structured epidemiological survey comprising all males born with severe haemophilia A (in all 100 patients, 19 with inhibitors) or haemophilia B (in all 16 patients, six with inhibitors) in Sweden in 1980-99. Our results show no protective effect of breastfeeding.
