[Pregnancy with an extremely rare P blood group with anti-PP1Pk].

The authors report on a successful pregnancy in a young Turkish patient with p and anti-PP1Pk-antibodies. Anti-PP1Pk is considered to cause haemolytic diseases in the newborn and habitual abortions. The patient was treated via plasma exchange and substitution with intravenous immunoglobulin. At 31 weeks of gestation the patient underwent Caesarean section due to growth retardation and pathological signs in the fetal CTG. The child has developed well up to two years after the delivery. Based on our data and a review of the literature, the effectiveness of therapy by plasmapheresis and/or immunoglobulin is discussed.
