Chronic inflammatory intestinal disorders in hidradenitis suppurativa

The objectives of this study were to determine the occurrence of CIID in HS and characterise this clinical population. Furthermore, the feasibility of using fecal calprotectin (FC) test or anti-Saccharomyces cerevisiae antibody (ASCA) levels to assess the colonic inflammation of CIID in HS patients was investigated. Methods: All newly diagnosed and untreated HS patients (n=74) were referred to a gastroenterologist for FC followed by colonoscopy after informed consent. C-reactive protein (CRP), white blood cell count, nucleotide-binding-oligomerisation-domain-containing-protein-2 (NOD2) polymorphism, and ASCA levels were measured. Patients were divided into HS-only and HS with CIID (HS+CIID) groups, based on the absence or presence of CIID. Laboratory and clinical parameters (age, gender, HS onset, clinical stage, family history, body mass index (BMI), smoking) were compared between the groups. Results: Thirteen patients complained gastrointestinal symptoms prior to any examination, including 11 in the HS+CIID group. The CIID frequency in HS was 28.4% (n=21/74), based on colonoscopy and histology. Significantly more patients had severe disease state in the HS+CIID group compared with the HS-only group, and BMI was significantly lower in the HS+CIID group (28.20 ±5.58 vs. 32.74±6.45, p=0.006). FC positivity occurred significantly more in HS+CIID patients compared with HS-only patients (90.48% vs. 3.77%, p
