DBE is defined as small intestinal endoscopy using two attached balloons. We included patients with stenosis which hampered passage of the scope and those who underwent DBE with observation for at least 80 cm from the ileocecal valve. Our new m SES-CD assesses the endoscopic activity of two consecutive small intestinal segments located 0-40 cm and 40-80 cm from the ileocecal valve by DBE,in addition to the activity of four colorectal segments. To compare the usefulness of m SES-CD with SES-CD,we similarly divided the patients into two groups according to total m SES-CD score(low disease activity group,< 4; high disease activity group,≥ 4). The clinical value of m SES-CD in predicting clinical outcome in patients with CD was evaluated using the occurrence of surgery after DBE as an endpoint.RESULTS:Median age of the 76 CD patients was 36 years(range,16-71). Thirty-nine patients had stenosis which hampered passage of the DBE to 80 cm on the proximal side from the ileocecal valve. Median evaluable length of small intestine by DBE was 80 cm(range,3-200). A total of 74 patients had one or more small intestinal lesions detected by DBE,of which 62(83.8%) were within 80 cm of the ileocecal valve on the proximal side. Only two patients(2.7%) with proximal-side lesions more than 80 cm from the ileocecal valve did not have lesions within 80 cm. Patients with high m SES-CD scores showed significantly shorter surgeryfree survival than those with low scores(P < 0.05). In contrast,surgery-free survival did not significantly differ between the low and high SES-CD groups(P > 0.05). Multivariate analysis by a Cox proportional hazards model identified m SES-CD as an independent factor for surgery-free survival.CONCLUSION:m SES-CD is useful in evaluating the risk of surgery-free survival in patients with CD.展开更多

Proton density(PD)-weighted, PD-weighted fat-suppressed(PD-FS), and postcontrast T1-weighted fat-suppressed(T1CE) images were used for evaluation. Using contrast and noncontrast images, our grading method for synovitis was performed to measure synovial thickness and signal intensity changes of the fat pad [Synovial membrane(SM) score], which was compared with the established methods,including MRI Osteoarthritis Knee Score(MOAKS), parapatellar synovitis score,Whole-Organ Magnetic Resonance Imaging Score(WORMS), and suprapatellar effusion diameter. Intraclass correlation coefficients(ICC) for intra and interobserver reproducibility and Spearman correlation coefficients(r) were calculated for the parapatellar synovitis score and each scoring method.RESULTS All of the scores presented substantial to almost perfect intrareliability. Among three readers, effusion diameter had substantial to almost perfect interreliability(ICC = 0.68-0.81) and WORMS had substantial interreliability(ICC = 0.61-0.70).For two out of three readers, there was substantial interreliability for the thickness score in T1CE(ICC = 0.55-0.69), SM scores in T1CE(ICC = 0.56-0.78)and PD-FS(ICC = 0.51-0.79), and parapatellar synovitis score in T1CE(ICC =0.53-0.72). The parapatellar synovitis score was significantly correlated with the thickness score in T1CE(r = 0.70) and the SM score in T1CE(r = 0.81) and PD-FS(r = 0.65).CONCLUSION The newly proposed quantitative thickness score on T1CE and the semiquantitative SM score on T1CE and PD-FS can be useful for Hoffa's fat pad synovitis.展开更多

The association study was performed for 112 single nucleotide polymorphisms (SNPs). We generated genetic risk scores (GRS) based on the number of risk alleles using weighted additive model. Discriminatory accuracy was measured by area under ROC curve (AUC). For risk evaluation, we divided individuals according to positive and negative likelihood ratios (LR) of a test, with LR > 5 for high risk group and LR < 0.20 for low risk group.RESULTS: The highest accuracy, AUC of 0.78 was achieved with GRS combining 33 SNPs with optimal sensitivity and specificity of 75.0% and 72.7%, respectively. Individuals with the highest risk (GRS > 5.54) showed significantly increased odds of developing CD (OR = 26.65, 95%CI: 11.25-63.15) compared to the individuals with the lowest risk (GRS < 4.57) which is a considerably greater risk captured than in one SNP with the highest effect size (OR = 3.24). When more than 33 SNPs were included in GRS, discriminatory ability was not improved significantly; AUC of all 74 SNPs was 0.76.CONCLUSION: The authors proved the possibility of building accurate genetic risk score based on 33 risk variants on Slovenian CD patients which may serve as a screening tool in the targeted population.展开更多

For risk evaluation, we divided individuals according to positive and negative likelihood ratios (LR) of a test, with LR > 5 for high risk group and LR < 0.20 for low risk group.RESULTS: The highest accuracy, AUC of 0.78 was achieved with GRS combining 33 SNPs with optimal sensitivity and specificity of 75.0% and 72.7%, respectively. Individuals with the highest risk (GRS > 5.54) showed significantly increased odds of developing CD (OR = 26.65, 95%CI: 11.25-63.15) compared to the individuals with the lowest risk (GRS < 4.57) which is a considerably greater risk captured than in one SNP with the highest effect size (OR = 3.24). When more than 33 SNPs were included in GRS, discriminatory ability was not improved significantly; AUC of all 74 SNPs was 0.76.CONCLUSION: The authors proved the possibility of building accurate genetic risk score based on 33 risk variants on Slovenian CD patients which may serve as a screening tool in the targeted population.
