Popis: The anti-PP1Pk is a rare antibody associated with recurrent miscarriages, mainly in the first half of pregnancy. There seems to be a direct correlation between the antibody titer and risk of miscarriage. As this is a rare entity, few case reports have been published. The most frequently proposed therapeutic approaches are double-filtration plasmapheresis and plasma exchange therapy. The rationale behind them is to remove the cytotoxic antibodies from maternal circulation. Here, we present the case of a 30-year-old woman with a history of two spontaneous miscarriages and a pre-conception anti-PP1Pk antibody titer of 1:4. As soon as she became pregnant, she was placed on prednisolone and low-molecular-weight heparin (LMWH). Biweekly antibody titers were performed throughout the entire gestation and remained below 1:16. As the titers were considered to be low, plasmapheresis was not performed. The pregnancy was uneventful and she delivered a healthy newborn child at 37 weeks of gestation, with no signs of anaemia.
