Two cases of abnormal liver function associated with H1N1 infection in pregnancy.

Two patients with recent H1N1 virus infection in pregnancy were found to have raised transaminases. They have both had a mild illness and have recovered with no adverse effects, and one has delivered a healthy baby while the other is still pregnant. We suggest that the deranged transaminase concentrations were directly linked to the viral infection in the first patient as the abnormal blood results predated treatment. The second case is less clear.
