Abstract

OBJECTIVES:
To describe the clinical characteristics, biochemical and histological features, outcomes and predictors of prognosis of children with autoimmune hepatitis (AIH) from a paediatric centre in South Africa.

METHODS:
Thirty-nine children diagnosed with AIH at Red Cross War Memorial Children's Hospital between 2005 and 2015 were included. Relevant patient's data were retrieved from the hospital's medical records and database. Liver biopsy slides were reviewed. Ethical approval was obtained. Data were analysed using SPSS.

RESULTS:
Females were 29 (74%). Mean age at presentation was 7.27 ± 3.35 years and the mean follow-up was 4.5 ± 2.4 years. Jaundice was present in 97% of patients at presentation. An acute presentation was observed in 26 (67%) even though cirrhosis was detected in 22 (56%). Autoantibody screening was completed in 35 patients, 20 (57%) were AIH-1, 1 (3%) was AIH-2 and 14 (40%) were seronegative AIH. Of the 25 patients who underwent magnetic resonance cholangiography 17 (68%) had associated autoimmune sclerosing cholangitis. The remission rate was 79%. However, 11 children relapsed later. One child required liver transplantation and one demised. Seronegative and seropositive patients have comparable characteristics and outcomes. While a higher alanine transaminase (ALT) level at presentation is a significant predictor of remission, a lower ALT level and cirrhosis are significant risk factors for unfavourable outcome. Overall survival rate was 97%.

CONCLUSION:
AIH responds well to therapy with excellent survival. Hence, it should be considered in any child presenting with viral screen negative hepatitis and start therapy timeously to prevent disease progression.
