IgA class reticulin antibodies in dermatitis herpetiformis: a good indicator of jejunal damage
Abstract:
Fifty patients with dermatitis herpetiformis (DH) were examined. Reticulin antibodies (RA) were found in 34 (68%) patients; 25 (73%) of them had IgA class RA, seven (21%) had IgA and IgG class RA, and two (6%) had IgG class RA. A good correlation was found between the occurrence of RA and the presence of jejunal villous atrophy. Twenty-four (96%) of the patients with subtotal villous atrophy and nine (82%) with partial villous atrophy had RA as compared to only one (7%) of the 14 patients with normal jejunal mucosa. Gluten-free diet treatment caused disappearance of RA in every patient, suggesting that RA measurements can also be used in DH for monitoring adherence to the diet treatment.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
