Probable blueberry-induced haemolysis in a G6PD deficient child: A case report.

BACKGROUND

Blueberry is a North American native fruit increasingly popular as a source of health-promoting bioactive compounds. However, there is evidence in the literature stating that blueberries should be avoided in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency.

CASE PRESENTATION

We report the first case of a G6PD deficient child who developed haemolysis approximately after half a day following the intake of fresh blueberry. He presented with the complaints of the passage of orange coloured urine and hurried breathing. The child had haemoglobin of 7.9 g/dl on admission day and the laboratory results were indicative of haemolytic process.

OUTCOMES AND IMPLICATIONS

During the stay in the hospital, the child was managed conventionally, and he improved both clinically and symptomatically. The child was discharged after four days of treatment and diet counselling was provided to his parents.

RECOMMENDATIONS

Our report should encourage further research on this fruit regarding the mechanism behind the development of haemolytic anaemia. Also, it is important in the case of G6PD deficient patients to take lifelong precautions to avoid the foods that can trigger haemolysis.
