[Treatment of a positive Rhesus D neonate born of a mother with idiopathic thrombopenic purpura with anti-D immunoglobulins (Rh O)]. / Traitement d'un nouveau-né Rhésus D positif né de mère atteinte d'un purpura thrombopénique idiopathique par immunoglobulines anti-D (Rh O).

A Rhesus D positive infant, born at 37 weeks of gestational age, admitted for neonatal passive immune thrombocytopenia was given 3 intravenous anti-Rhesus D immunoglobulin infusions at 3 weeks of age. This thrombocytopenia which had not responded to conventional therapy improved after the third of anti-Rhesus D immunoglobulin infusion, but the efficacy of this treatment could not be proven in this case report. However, the tolerance was good. No side-effects (jaundice, severe anemia) were observed.
