BACKGROUND AND AIMS: Risk factors for peristomal pyoderma gangrenosum (PPG) are not well defined. The aim of this study was to evaluate risk factors associated with development of PPG.
METHODS: Both PPG patients and controls were obtained by searching a database of the Cleveland Clinic using the ICD-9 code from March 2005 to May 2011. The control group was selected by matching for underlying diseases and type of stoma in a ratio of 3:1. Univariate and multivariate analyses were performed.
RESULTS: A total of 15 PPG cases and 45 controls were included. The mean age at the time of PPG diagnosis was 46.0 ± 14.4 years. The underlying disease was Crohn's disease in 7 patients (46.7%), ulcerative colitis in 7 (46.7%) and indeterminate colitis in 1 (6.7%). Eleven patients (73.3%) had end ileostomy, 3 (20.0%) had loop ileostomy and 1 (6.7%) had colostomy. Eleven patients (73.3%) had active intestinal disease. In multivariate analysis, female gender, the presence of concurrent autoimmune disorders, and a high body mass index (BMI) were significantly associated with the presence of PPG, with odds ratios of 8.385 (95% confidence interval [CI]: 1.496-46.982, p=0.015), 6.882 (95% CI:1.438-32.941, p=0.016), and 9.895 (95% CI: 1.970-43.704, p=0.005), respectively. After a median follow-up of 12.8 (interquartile range: 7.9-20.1) months with appropriate therapy, PPG healed in 8 patients (53.3%) and improved in 7 (46.7%) patients, after treatment.
CONCLUSIONS: Female gender, the presence of autoimmune disorders and a high BMI appeared to be associated with an increased risk for the development of PPG in IBD patients.
