Idiopathic non-syphilitic paroxysmal cold haemoglobinuria in children.

Syphilitic paroxysmal cold haemoglobinuria. Case report and study of the Coombs test.

A case of congenital syphilis which presented with paroxysmal cold haemoglobinuria is described. The patient had aortic incompetence, and the significance of this finding is discussed. The Coombs test was studied, and positive results appear to be due to interaction between antiglobulin serum and complement adsorbed on to the test cells, this adsorption being promoted by the cold antibodies.

Paroxysmal cold haemoglobinuria and measles.

With the increasing control of congenital syphilis, paroxysmal cold haemoglobinuria has become a very rare disorder in childhood. Cases which occur now are more likely to be associated with acute infectious diseases (Kissmeyer-Nielsen and Schleisner, 1963). However, despite the frequency of measles in children, paroxysmal cold haemoglobinuria (PCH) has only previously been described as a compli...

Diagnostic difficulties in a patient with paroxysmal cold haemoglobinuria and acute kidney injury

Paroxysmal cold haemoglobinuria (PCH) is a form of autoimmune haemolytic anaemia (AIHA) characterised by a sudden onset of haemoglobinuria, either spontaneously or following exposure to cold. In children, it is commonly seen following a viral illness or after immunisation. Diagnosis of PCH is confirmed by a positive Donath Landsteiner (DL) test in which biphasic haemolysins are detected. Howeve...

Serological Findings in a Child with Paroxysmal Cold Haemoglobinuria

PCH is a rare autoimmune hemolytic anemia (AIHA) but is one of the most common causes of AIAH in children. For the diagnosis, it is important to perform the appropriate methods of serological investigation and show the typical biphasic reaction. This is a case report of a child who presented with features of haemolysis and was diagnosed with PCH of this way.
