Abstract
Methods. We reviewed the medical records of 74 patients diagnosed with hepatobiliary disease between 2000 and 2011, assessing clinical outcome and potential risk factors. Patients, categorised into those with and those without BA, were compared in terms of CMV infection.
Results. The 74 patients included 39 (52%) BA and 35 non-BA patients; following the exclusion of patients due to insufficient data, 27 (69%) BA and 31 non-BA patients were reviewed. Twenty-one (78%) BA patients were CMV-positive (IgM/IgG), including 20 IgM-positive patients versus 8 in the non-BA group (p<0.01). Two (7.5%) CMV-IgM-positive BA infants were HIV-exposed versus 7 (35%) in the non-BA group (p<0.01). Long-term outcomes included 3 deaths in the non-HIV CMV-positive group and a higher rate of severe early liver damage, suggesting a poorer outcome in CMVaffected patients.
Conclusions. Our results suggest a correlation between CMV exposure/infection and BA which affects clinical outcome. HIV positivity
does not preclude BA and should be investigated further.
