Background. The aim of this study was to evaluate the interobserver variability in diagnosing inflammatory bowel disease (IBD)-associated neoplasia among practicing pathologists from China using telepathology, a practice of remote diagnostic consultation increasingly used nationally and internationally, and its comparison with the interpretation of subspecialized gastrointestinal (GI) pathologists from the United States (US).Methods. Eight GI pathologists from the US and 4 pathologists from China with an interest in GI pathology participated in this study. A total of 50 colonic biopsies from patients with a clinical history of IBD from 8 medical centers in China were included. All microscopic slides in each case were digitized using an Aperio system. One pathologist (XL) reviewed the digitized full-slide images, and selected areas of interest were captured at low, medium, and high magnifications at a resolution of 1712 × 1072 pixels and saved as tagged image file format (TIFF) files on read-only DVD. Each pathologist evaluated the images and selected the most appropriate diagnostic category for each case (negative, indefinite, low-grade dysplasia [LGD], high-grade dysplasia [HGD], and carcinoma). A Fleiss’ kappa coefficient (K) analysis was performed to determine interobserver agreement and the agreement of each pathologist from China with the consensus diagnosis (defined as diagnostic agreement by at least 4 participating US GI pathologists).Results. There was substantial interobserver agreement among 4 pathologists from China on the interpretation of IBD-associated neoplasia (kappa value 0.68, 95% confidence interval: 0.56–0.78). A consensus diagnosis included negative (n=22), LGD (n=22), HGD (n=3), carcinoma (n=2), and indefinite for dysplasia (n=1). Using consensus diagnoses as references, the agreement between each pathologist from China and the consensus diagnosis was substantial with kappa values ranging from 0.75 to 0.80.Conclusions. This study reveals substantial interobserver agreement for the interpretation of colonic neoplasia in IBD using digitized images among Chinese pathologists as well as between each Chinese pathologist and a consensus diagnosis generated by US GI pathologists.

Összefoglaló. Gyulladásos bélbetegségben (IBD) a fájdalomérzés komplex szomatikus és pszichés jelenség. Ez utóbbi komponens pontosabb megértése segíthet a megfelelő kezelési stratégia megállapításában. A szorongásos hangulati zavarok és egyes maladaptív viselkedési minták (dohányzás és alkoholfogyasztás) előfordulási gyakorisága jól dokumentált IBD-ben, a kannabiszhasználat hatása ugyanakkor kevésbé ismert. A szerzők szisztematikus áttekintést végeztek annak megértéséhez, hogy vajon magasabb-e a marihuánahasználat gyakorisága felnőtt IBD-s betegek között egészséges kontrollpopulációhoz viszonyítva, és ha igen, akkor melyek a szerhasználat legfontosabb jellemzői. A kutatási periódust szándékosan az elmúlt 7 évre korlátoztuk, ugyanis 2013-tól jelentős változások álltak be a kannabinoidok jogi és orvosi megítélésében az USA-ban. Öt elsődleges és több másodlagos adatbázisban kutattunk előre meghatározott kulcsszavak segítségével 2013 óta teljes szöveggel megjelent, angol nyelvű felnőtt IBD-s populációt vizsgáló epidemiológiai tanulmányok vonatkozásában. 143 rekord közül 7 cikk felelt meg a beválogatási kritériumoknak. Eredményeink szerint a kannabiszhasználat gyakorisága IBD-ben szenvedő felnőtt betegek körében valószínűleg magasabb, mint a kontrollpopulációban: a „valaha, bármikor” használók aránya 54–70% között változott (szemben a 46–60% gyakorisággal a kontrollcsoportban), míg az „aktív használók” esetén a gyakoriság 6,8–25% között változott (vs. a kontrollcsoportban tapasztalt 8,6–14%-kal). A prevalenciaadatok széles variabilitása arra utal, hogy a beválogatott epidemiológiai tanulmányok valószínűleg vagy nem voltak megfelelően tervezve, vagy jelentős heterogenitással bírtak. A pszichés tényezők ellentmondásos mintája azt sugallja, hogy a kannabinoidok egyes esetekben ronthatták, más esetben valószínűleg javították bizonyos prominens tünetek megélését. Javasoljuk ezért, hogy a valós prevalencia megállapítása érdekében a keresztmetszeti vizsgálatok mellé ismételt pszichometriai vizsgálatokon alapuló vizsgálatok is bekerüljenek a további kutatásba. Orv Hetil. 2021; 162(12): 443–448. Summary. Pain perception in inflammatory bowel disease (IBD) is beyond a purely somatic process. In-depth understanding of psychologic elements might enable more effective management in this patient group. Anxiety disorders and certain maladaptive coping strategies like smoking and alcohol consumption are well-documented in IBD, unlike the scarcely researched cannabis use. The authors designed a systematic review, to investigate if the prevalence of cannabis use is higher in IBD that in unselected controls. The research window was intentionally set to cover for the past 7 years, as in 2013 major legislative changes took place in the cannabis decriminalisation process in the United States. 5 primary and several secondary databases were researched with a pre-formulated algorithm registered at PROSPERO for full text epidemiological studies published in English language involving adult IBD patients. Out of 143 records, 7 articles met the in/exclusion criteria. Our results suggest that cannabis use among adult patients with IBD is likely to be higher than in the unselected control population. The proportion of “ever” users varied from 54% to 70% (vs. 46–60% in the control group); and for ‘active users’, the prevalence ranged between 6.8% to 25% (vs. 8.6–14% in the control group). The wide variability in prevalence data suggests that the selected epidemiological studies were either inappropriately designed or were too heterogeneous (or both). The contradictory pattern of psychological factors suggests that cannabinoids might improve or worsen IBD depending on case by case basis. We therefore opine that in addition to cross-sectional papers, studies based on repeated psychometric analysis are needed to establish the real prevalence and inform cannabinoid prescription and holistic management in inflammatory bowel disease.
