title: Recurrent paroxysmal cold haemoglobinuria in a 3-year-old child: a case report.
abstract: We present the case of a 3-year-old girl who presented on two separate occasions, eight months apart, with typical features of paroxysmal cold haemoglobinuria (PCH). On each occasion, she suffered malaise and fever with dark urine following an upper respiratory tract infection. She developed severe anaemia and required transfusion of red cells on both occasions, although each time she made a quick recovery. She was found to be direct antiglobulin test-positive with anti-C3d, and agglutination was observed on the blood film. A biphasic Donath-Landsteiner antibody was demonstrated. The specificity of the antibody was not identified, although it was not anti-P. As far as we are aware, recurrence of acute PCH in a child has not been previously reported in the literature.
