Presenting phenotype of paediatric inflammatory bowel disease (PIBD) in Wessex, southern England 2010-13

Abstract

Aim: there has been at least a two-fold increase in the incidence of PIBD over the last 20 years; we report the presenting features from 2010-13 and compare with previous data.

Methods: all patients diagnosed with PIBD at University Hospitals Southampton from 2010-2013 were identified from an in-house database. Data were obtained from paper and electronic notes. Height, Weight and BMI SDS are presented as median values (95% CI).

Results: 172 patients were included (median age at diagnosis 13.5, 115 male); CD- 107, UC- 50, IBDU- 15. The most common presenting features of CD were abdominal pain (86%), diarrhoea (78.5%) and weight loss (56.1%); 42.1% of patients had all three. In UC blood in stool (92%), diarrhoea (92%) and abdominal pain (88%) were the most common; all three in 76% of patients.

CD presented with ileocolonic disease in 52.5%. UC presented with pancolitis in 64%.

There was growth delay in CD: height -0.37(-0.60 to -0.14); Weight -1.09 (-1.35 to -0.83). Growth was maintained in UC: height 0.53 (0.19 to 0.87); weight 0.14 (-0.20 to 0.48).

Conclusion: PIBD phenotype remains as extensive despite increasing incidence. Although the classical phenotype is common a reasonable proportion present with atypical features, normal growth and normal blood markers
