BACKGROUND: Vitamin K deficiency bleeding is a life-threatening complication in early infancy. Exclusive breastfeeding and neonatal cholestasis syndromes, most notable α-1-antitrypsin deficiency, have been reported to be risk factors. Intracranial haemorrhage is most common. No association to haemopericardium has been reported before.
CASE SUMMARY: We report on an 11 weeks old at term-born infant, who presented with severe anaemia and signs of cardiogenic shock. Immediately echocardiography was done and depicted cardiac tamponade. Pericardiocentesis was performed and a significant amount of haemorrhagic fluid was removed. Further workup revealed deranged coagulation parameters, cholestatic liver disease, and reduced α-1-antitrypsin levels. Despite normal brain sonography, a small cerebral haemorrhage was detected on magnetic resonance imaging. A genetic test finally proofed homozygotic mutation of the SERPINA1-gene and confirmed the diagnosis of α-1-antitrypsin deficiency as the underlaying cause. After initial replacement of coagulation factors, erythrocytes and vitamin K, the infant recovered. Eighteen weeks after discharge, the infant is still on vitamin K supplementation. She did not have any further bleedings and no neurologic or developmental impairment.
DISCUSSION: Alpha-1-antitrypsin deficiency can lead to vitamin K deficiency in young infants even with adequate prophylaxis. Spontaneous haemorrhagic pericardial effusion was a new manifestation of vitamin K deficiency bleeding in our patient and should be considered and ruled out in young infants who present with acute anaemia and poor clinical condition.
