[RHnull syndrome--diagnostic and therapeutic problems].
A very rare Rhnull phenotype as a cause of haemolytic anaemia in a female patients was for the first time detected in Poland. The beneficial influence of splenectomy was demonstrated. It was proved that a single transfusion of Rh negative red cell concentrate, because of the lack of Rhnull blood, did not cause any acute adverse reactions. However, a transient, subclinical delayed haemolytic reaction due to the stimulation of anti-c and anti-e was observed.
