UNLABELLED: A cholestatic 6-mo-old girl was admitted to our department because she recently presented with hypotonia and lethargy, apparently due to moderate and transient hypoglycaemia. Her urine contained 3-hydroxy-dicarboxylic acids of 12 to 14 carbons in length and her plasma acylcarnitine profile was consistent with long-chain 3-hydroxyacylCoA dehydrogenase deficiency. This diagnosis was confirmed by enzyme studies. This deficiency was due to a G1528C mutation on the paternal allele (mutation on the maternal allele as yet not identified). The patient improved dramatically with medium-chain triglyceride supplementation. CONCLUSION: Early cholestasis and hepatic fibrosis must lead to search for long-chain 3-hydroxyacylCoA dehydrogenase deficiency, particularly when hypoketotic hypoglycaemia is present.
