Current Status of Opportunistic Infection in Inflammatory Bowel Disease Patients in Asia: A Questionnaire-Based Multicenter Study.

ABSTRACT:

Background/aims

Opportunistic infection in inflammatory bowel disease (IBD) has become a serious problem. However, its status of doctors' opinions and test equipment in hospitals are unclear. The aim of the study was to investigate these issues to improve the prognosis of IBD patients.

Methods

This retrospective, multicenter study was conducted by 83 investigators who were members of the Asian Organization for Crohn's and Colitis. Data on opportunistic infection were collected from hospital databases between January 2017 and December 2017. The survey consisted of 11 items.

Results

Most physicians appreciated the diagnostic value of tissue cytomegalovirus (CMV) DNA, accounting for 86.1% of members in China, 37.5% in Japan, 52.9% in South Korea, and 66.7% in Southeast Asia. Only 83.1% of hospitals had the ability to test for CMV immunohistochemistry in Asia. Hepatitis B surface antigen (HBsAg) screening was recommended by all members. However, only 66.7% in China, 70.6% in South Korea, and 66.7% in Southeast Asia agreed to routinely vaccinate IBD patients when HBsAg tested negative. Most members preferred metronidazole (74.7%) as the first choice for patients with Clostridium difficile infection. However, the proportion of stool C. difficile toxin test was lower in China than in other areas (75.0% in China vs 95.8% in Japan and 100% in South Korea and Southeast Asia, p<0.05).

Conclusions

Opportunistic infection from CMV, hepatitis B virus, and C. difficile should be of high concern for IBD patients. More efforts are needed, such as understanding consensus in clinical practice and improving testing facilities in hospitals.

Project description:BackgroundInflammatory Bowel Disease (IBD), which includes both Crohn's disease (CD) and ulcerative colitis (UC), is caused by a complex interplay involving genetic predisposition, environmental factors and an infectious agent. Mycobacterium avium subsp. paratuberculosis (MAP) is a promising pathogen candidate since it produces a chronic intestinal inflammatory disease in ruminants that resembles CD in humans. MAP is a ubiquitous microorganism, although its presence in the food chain, especially in milk from infected animals, is what made us think that there could be an association between lactase persistence (LP) and IBD. The LCT mutation has brought adaptation to dairy farming which in turn would have increased exposure of the population to infection by MAP. NOD2 gene mutations are highly associated to CD.MethodsIn our study, CD and UC patients and controls from the North of Spain were genotyped for the lactase gene (LCT) and for three NOD-2 variants, R702W, G908R and Cins1007fs. MAP PCR was carried out in order to assess MAP infection status and these results were correlated with LCT and NOD2 genotypes.ResultsAs for LP, no association was found with IBD, although UC patients were less likely to present the T/T-13910 variant compared to controls, showing a higher C-allele frequency and a tendency to lactase non-persistence (LNP). NOD2 mutations were associated to CD being the per-allele risk higher for the Cins1007fs variant. MAP infection was more extended among the healthy controls (45.2%) compared to CD patients (21.38%) and UC patients (19.04%) and this was attributed to therapy. The Asturian CD cohort presented higher levels of MAP prevalence (38.6%) compared to the Basque CD cohort (15.5%), differences also attributed to therapy. No interaction was found between MAP infection and LCT or NOD2 status.ConclusionsWe conclude that LP is not significantly associated with IBD, but that MAP infection and NOD2 do show not mutually interacting associations with IBD.
