Abstract

To investigate the association between chronic cholestatic jaundice, systemic immunity, and various infectious complications in patients with biliary atresia (BA), we performed a survey of the systemic immune function in 30 children with BA. Patients were divided into a jaundice group (total serum bilirubin > or = 2 mg/dL for >6 mo) and control group (total serum bilirubin <2 mg/dL for >6 mo) with comparable age. Patients were tested for serum immunoglobulin and complement levels, mitogen response, interleukin (IL)-4, IL-5, and interferon-gamma production after phytohemagglutinin (PHA) stimulation, blood cell and lymphocyte subpopulation counts, phagocytic function, and leukocyte adhesion complex. They were then followed prospectively for 6 mo, and severe infectious complications requiring hospitalization were recorded. Compared with jaundice-free patients, T-lymphocyte proliferation function, determined by PHA mitogen test was significantly lower (p = 0.02) in BA patients with chronic cholestatic jaundice after a Kasai operation. During the study period, patients with chronic cholestatic jaundice had a higher risk of severe infectious complications than their jaundice-free counterparts (risk ratio = 5.87; p = 0.001). In conclusion, BA patients with chronic cholestatic jaundice are associated with impairment of T-lymphocyte proliferation and increased incidence of severe infectious complications.
