Haemolysis in a G6PD‐deficient child induced by eating unripe peaches

A child suffering from G6PD deficiency developed a severe haemolytic crisis without an apparent trigger. The possible pathogenetic role of the ingestion of unripe peaches was studied biochemically in this anaemia. We show that an extract from the unripe peach exerts an oxidative challenge on normal as well as on asymptomatic G6PD‐deficient erythrocytes. This effect is analogous to that of the favism‐inducing agents. The effect of the extract on the patient's red blood cells was more pronounced than on other asymptomatic G6PD‐deficient erythrocytes, particularly during his haemolytic crisis. The chemical nature of the deleterious component was not identified. It is suggested that unripe peaches be added to the list of hazards for G6PD‐deficient subjects in combination with other factors.
