Abstract |
Hereditary fructose intolerance(HFI) is an autosomal recessive disease caused by catalytic deficiency
of aldolase B in which affected homozygotes develop hypoglycemia and abdominal symptoms
after taking foods containing fructose. Chronic exposure to fructose may lead to progressive
hepatic injury, renal injury, growth retardation, and ultimately to liver and kidney failure. Herein,
we report a case of HFI with presentation of episodic vomiting, diarrhea, cold sweating, abnormal
liver function and failure to thrive after 12 months of her age. She developed an aversion to
fruits and sweet-tasting foods. When she was admitted to hospital at the age of 30 months, hepatomegaly,
and dysfunction of proximal renal tubule with renal tubular acidosis were noted. We
confirmed the diagnosis via enzyme assay on biopsied liver and intestine. A fructose restrictied
diet was recommended. The patient has been symptom free with normal liver functions since
then. |
