Maternal liver disease has been reported to be more frequent in women carrying a foetus affected by a fatty acid oxidation disorder (FAOD). We report a day three infant who presented acutely with hypoglycaemia and high anion gap metabolic acidosis. The pregnancy had been complicated by maternal hypertension progressing to pre-eclampsia from 36 weeks then maternal haemolysis, elevated liver enzymes and a low platelet count (HELLP syndrome) at 38 weeks. The mother required platelet transfusions before and after delivery. A female infant, delivered by planned caesarean section, was initially well.
At forty-eight hours of life, the infant became anorexic, lethargic, tachypnoeic and 4 hours later rapidly deteriorated with hypoglycaemia, hyperammonaemia, metabolic (mainly lactic) acidosis, mild liver transaminitis, coagulopathy, hyperuricaemia and uraemia. She responded quickly to cessation of protein feeds and intravenous 10% dextrose/normal saline infusion. Rapid acylcarnitine analysis diagnosed glutaric aciduria type II (GAII). Intravenous fluids were continued for 48hrs with a gradual increase in oral feeds with fat initially restricted to 25% of calories. Repeat acylcarnitine profile after 48 hours of therapy was normal and the fat restriction is being gradually eased. The mother recovered over 5 days and her acylcarnitine profile was also normal.
Conclusion: Although the association between fetal FAODs and maternal liver disease is debated by some, in this case the maternal HELLP syndrome directed the clinicians to prioritize testing for a FAOD. We cannot find a previous publication on the association of maternal liver disease and glutaric aciduria type II.
