Aim:
A review of the literature concerning the very rare anti-PP1Pk isoimmunisation with a personal case.
Clinical Material:
Anti-PP1k antibody gives rise to the high risk of abortion in the first and the second trimester (in a different series the risk is 50-70%). A 19-year-old patient who had this antibody was helped by a plasmaphoresis repeatedly between the 6th and the 25th week of pregnancy. Cordocentesis was carried out to estimate fetal haemoglobin from the 25th week onwards. A set caesarean section was carried out at 36 weeks because of intrauterine growth retardation and the development of fetal anaemia.
Discussion:
The authors suggest research based on the known immunohaematological factors concerned with this isoimmunisation and on the main treatments available (plasmaphoresis, cordocentesis, and delivery at a set time).
Conclusion:
Until now there have been very few cases and only four similar cases to ours have been reported in the literature. That is why it is so difficult to suggest a well defined strategy for treating these patients.
