Perianal Crohn's Disease is Associated with Distal Colonic Disease, Stricturing Disease Behavior, IBD-Associated Serologies and Genetic Variation in the JAK-STAT Pathway.

ABSTRACT:

Background

Perianal Crohn's Disease (pCD) is a particularly severe phenotype associated with poor quality of life with a reported prevalence of 12%-40%. Previous studies investigating the etiology of pCD have been limited in the numbers of subjects and the intensity of genotyping. The aim of this study was to identify clinical, serological, and genetic factors associated with pCD.

Methods

We performed a case-control study comparing patients with (pCD+) and without perianal (pCD) involvement in CD; defined as the presence of perianal abscesses or fistulae. Data on demographics and clinical features were obtained by chart review. Inflammatory bowel disease-related serology was determined by enzyme-linked immunosorbent assay. Genetic data were generated using Illumina genotypin
