The significance of elevated serologic markers of celiac disease in children with juvenile rheumatoid arthritis.
OBJECTIVE
The aim of this study is to determine the frequency of celiac disease (CD) in a group of children with juvenile rheumatoid arthritis (JRA) and determine the correlation between the presence of the serologic markers and the histological diagnosis of CD.


METHODS
Forty-two children (24 females) with JRA, aged between 5-15 years underwent study of serologic markers for CD (gliadin-IgA, gliadin-IgG, reticulin and endomysium-IgA antibodies). Endoscopic intestinal biopsy was performed in patients who had positive serologic markers for CD. The diagnosis of CD was based on the classic finding of villous atrophy and crypt hypertrophy.


RESULTS
Eighteen patients (42.8%) had serologic markers for CD; ten of them with a systemic form, five with a polyarticular form and three with a pauciarticular form of JRA. Levels of AGA -IgG were high in 14 patients (77.8%), four patients (22.2%) had high levels of AGA-IgA and seven patients (38.9%) had anti-endomysium antibodies (AEA). One patient had anti-reticulin antibodies (ARA) 5.5%. Sixteen patients underwent intestinal biopsy; in only one patient with AEA antibodies (2.38%), biopsy revealed typical finding of CD. The patient with CD showed improvement in both growth parameter as well as articular symptoms after starting gluten-free diet


CONCLUSIONS
Our study shows that the screening for silent CD among children with JRA may be useful. Those patients with AEA need further follow up since these antibodies are quite sensitive and specific for CD.
