Paroxysmal cold haemoglobinuria and measles.

Idiopathic non-syphilitic paroxysmal cold haemoglobinuria in children.

Three examples of non-syphilitic paroxysmal cold haemoglobinuria (PCH) in children are described which occurred, within a period of 16 days, in association with a febrile illness. No definite viral aetiology or obvious epidemiological association could be established. A Donath-Landsteiner antibody of anti-P specificity was demonstrated in all three patients. The serological aspects of PCH are c...

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.

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...

Intrahepatic gas shadows in neonatal duodenal obstruction.

fractions C2, C3, and C4 are required in the warm phase, and fraction Cl is probably required in the cold phase (Hinz, Picken, and Lepow, 1961). Since the introduction of penicillin treatment for syphilis, PCH has become much less common, and an increasing proportion of cases is now seen in association with acute viral infections (Dacie, 1962). In the majority of virus-associated cases the atta...
