Haemolysis in a G6PD-deficient child induced by eating unripe peaches
Insights
Unripe peaches may trigger severe hemolytic crisis in children with glucose-6-phosphate dehydrogenase (G6PD) deficiency. Biochemical analysis revealed unripe peach extract causes oxidative stress on red blood cells, similar to favism-inducing agents.
Area of Science:
- Biochemistry
- Hematology
- Pediatrics
Background:
- Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an inherited condition causing hemolytic anemia.
- Patients with G6PD deficiency are susceptible to oxidative stress triggered by certain foods and drugs.
- The specific triggers for hemolytic crises are not always apparent.
Observation:
- A child with G6PD deficiency experienced a severe hemolytic crisis without a clear cause.
- The study investigated the potential role of unripe peach ingestion in this event.
- Biochemical analysis was performed on red blood cells (erythrocytes) from the patient and controls.
Findings:
- Extract from unripe peaches induced significant oxidative stress on normal and G6PD-deficient erythrocytes.
- This oxidative effect is comparable to that of known favism-inducing agents.
- The patient's erythrocytes showed a more pronounced reaction to the peach extract, especially during the crisis.
Implications:
- Unripe peaches should be considered a potential hazard for individuals with G6PD deficiency.
- This finding may help explain previously unexplained hemolytic crises in G6PD-deficient patients.
- Further research is needed to identify the specific component in unripe peaches responsible for the oxidative damage.
Abstract:
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.
