- Abstract
Importance: Use of thiopurines may be limited by myelosuppression. TPMT pharmacogenetic testing identifies only 25% of at-risk patients of European ancestry. Among patients of East Asian ancestry, NUDT15 variants are associated with thiopurine-induced myelosuppression (TIM). Objective: To identify genetic variants associated with TIM among patients of European ancestry with inflammatory bowel disease (IBD). Design, Setting, and Participants: Case-control study of 491 patients affected by TIM and 679 thiopurine-tolerant unaffected patients who were recruited from 89 international sites between March 2012 and November 2015. Genome-wide association studies (GWAS) and exome-wide association studies (EWAS) were conducted in patients of European ancestry. The replication cohort comprised 73 patients affected by TIM and 840 thiopurine-tolerant unaffected patients. Exposures: Genetic variants associated with TIM. Main Outcomes and Measures: Thiopurine-induced myelosuppression, defined as a decline in absolute white blood cell count to 2.5 × 109/L or less or a decline in absolute neutrophil cell count to 1.0 × 109/L or less leading to a dose reduction or drug withdrawal. Results: Among 1077 patients (398 affected and 679 unaffected; median age at IBD diagnosis, 31.0 years [interquartile range, 21.2 to 44.1 years]; 540 [50%] women; 602 [56%] diagnosed as having Crohn disease), 919 (311 affected and 608 unaffected) were included in the GWAS analysis and 961 (328 affected and 633 unaffected) in the EWAS analysis. The GWAS analysis confirmed association of TPMT (chromosome 6, rs11969064) with TIM (30.5% [95/311] affected vs 16.4% [100/608] unaffected patients; odds ratio [OR], 2.3 [95% CI, 1.7 to 3.1], P = 5.2 × 10-9). The EWAS analysis demonstrated an association with an in-frame deletion in NUDT15 (chromosome 13, rs746071566) and TIM (5.8% [19/328] affected vs 0.2% [1/633] unaffected patients; OR, 38.2 [95% CI, 5.1 to 286.1], P = 1.3 × 10-8), which was replicated in a differen, Funding Agencies:International Serious Adverse Events Consortium Crohn's Colitis UK Wellcome Trust WT097835MF National Institutes of Health P01DK046763

- Abstract
Pancreatitis occurs in approximately 4% of patients treated with the thiopurines azathioprine or mercaptopurine. Its development is unpredictable and almost always leads to drug withdrawal. We identified patients with inflammatory bowel disease (IBD) who had developed pancreatitis within 3 months of starting these drugs from 168 sites around the world. After detailed case adjudication, we performed a genome-wide association study on 172 cases and 2,035 controls with IBD. We identified strong evidence of association within the class II HLA region, with the most significant association identified at rs2647087 (odds ratio 2.59, 95% confidence interval 2.07-3.26, P = 2 x 10(-16)). We replicated these findings in an independent set of 78 cases and 472 controls with IBD matched for drug exposure. Fine mapping of the H LA region identified association with the HLA-DQA1*02:01-HLA-DRB1*07:01 haplotype. Patients heterozygous at rs2647087 have a 9% risk of developing pancreatitis after administration of a thiopurine, whereas homozygotes have a 17% risk., Funding Agencies:International Serious Adverse Events Consortium (iSAEC)Crohn's and Colitis UKWellcome Trust Institutional Strategic Support Award

- Abstract
Background/aims: Upadacitinib is a novel selective Janus kinase inhibitor approved for use in ulcerative colitis. Clinical trials had rigorous criteria and excluded many patient subgroups. Given limited real-world effectiveness data, we examined outcomes of patients treated with upadacitinib for ulcerative colitis in a real-world population., Methods: Patients that commenced upadacitinib for moderate-to-severe ulcerative colitis from September 2022 until March 2023 were identified at 13 inflammatory bowel disease centers across Australia. Clinical, biochemical, endoscopic, and intestinal ultrasound outcomes were recorded retrospectively at baseline, week 8, and week 16., Results: One hundred and fifty-two patients (61 female [40%], median age 38 years [interquartile range, 28-50]) were included. The primary endpoint of clinical remission was met in 79% at week 8, and 84% at week 16. A total of 42 patients (28%) with prior tofacitinib exposure were included. No significant difference in clinical remission was observed by week 16 between tofacitinib experienced compared to tofacitinib naïve patients (86% vs. 84%, P= 0.67). Complete intestinal ultrasound data was available for 36 patients, showing transmural remission in 64% at week 8 and 81% at week 16, with a decrease in median bowel wall thickness of 2.3 mm and 2.4 mm, respectively., Conclusions: Upadacitinib resulted in high rates of clinical remission at 8 and 16 weeks in this large real-world cohort of ulcerative colitis patients. Upadacitinib is effective in patients with prior tofacitinib exposure. Intestinal ultrasound shows significant rates of transmural remission at week 8, sustained through week 16.

- Abstract
Background: An inverse relationship exists between inflammation and testosterone concentrations in non-inflammatory bowel disease (IBD) immune conditions but has not been objectively explored in the IBD male population. We aimed to characterize the distribution of testosterone concentrations in a cohort of males with IBD and identify any relationship between testosterone levels and disease activity., Methods: We conducted a prospective cross-sectional study of male IBD patients. Demographics, disease characteristics, sex-hormone concentration, gonadotropins, C-reactive protein, fecal calprotectin, and patient-reported outcomes on quality of life and erectile function were collected. Relationships between disease activity, biomarkers, patient-reported outcome scores, and testosterone levels were analyzed using univariate and multivariate linear regression analyses., Results: A total of 85 male IBD patients were included with a mean age 44 ± 14.1 years, of which 49.4% had Crohn's disease. Mean testosterone concentration was 15.4 ± 5.2 nmol/L and 17.6% had a serum testosterone <10.4 nmol/L. Active disease was associated with lower testosterone concentrations in univariate analysis (β ± SE = -0.25 ± -1.99, P = .02) but not in multivariate analysis (β -0.18 ± 1.75, P = .06). Testosterone concentrations were independently associated with sex hormone-binding globulin levels (β ± SE = 0.45 ± 0.04, P < .0001) and a younger age (β ± SE = -0.32 ± 0.04, P <.0001). Erectile function scores (5-item International Index of Erectile Function) were lower in IBD patients with a longer duration of disease (β ± SE = -0.24 ± 0.006, P = .04)., Conclusions: Lower testosterone concentrations in men with IBD may reflect confounding from other factors and are not independently associated with disease activity. Greater awareness and screening for sexual dysfunction should occur in males with IBD, particularly in those with a longer disease duration., (© The Author(s) 2024.

- Abstract
Importance: Use of thiopurines may be limited by myelosuppression. TPMT pharmacogenetic testing identifies only 25% of at-risk patients of European ancestry. Among patients of East Asian ancestry, NUDT15 variants are associated with thiopurine-induced myelosuppression (TIM)., Objective: To identify genetic variants associated with TIM among patients of European ancestry with inflammatory bowel disease (IBD)., Design, Setting, and Participants: Case-control study of 491 patients affected by TIM and 679 thiopurine-tolerant unaffected patients who were recruited from 89 international sites between March 2012 and November 2015. Genome-wide association studies (GWAS) and exome-wide association studies (EWAS) were conducted in patients of European ancestry. The replication cohort comprised 73 patients affected by TIM and 840 thiopurine-tolerant unaffected patients., Exposures: Genetic variants associated with TIM., Main Outcomes and Measures: Thiopurine-induced myelosuppression, defined as a decline in absolute white blood cell count to 2.5 × 109/L or less or a decline in absolute neutrophil cell count to 1.0 × 109/L or less leading to a dose reduction or drug withdrawal., Results: Among 1077 patients (398 affected and 679 unaffected; median age at IBD diagnosis, 31.0 years [interquartile range, 21.2 to 44.1 years]; 540 [50%] women; 602 [56%] diagnosed as having Crohn disease), 919 (311 affected and 608 unaffected) were included in the GWAS analysis and 961 (328 affected and 633 unaffected) in the EWAS analysis. The GWAS analysis confirmed association of TPMT (chromosome 6, rs11969064) with TIM (30.5% [95/311] affected vs 16.4% [100/608] unaffected patients; odds ratio [OR], 2.3 [95% CI, 1.7 to 3.1], P = 5.2 × 10-9). The EWAS analysis demonstrated an association with an in-frame deletion in NUDT15 (chromosome 13, rs746071566) and TIM (5.8% [19/328] affected vs 0.2% [1/633] unaffected patients; OR, 38.2 [95% CI, 5.1 to 286.1], P = 1.3 × 10-8), which was replicated in a different cohort (2.7% [2/73] affected vs 0.2% [2/840] unaffected patients; OR, 11.8 [95% CI, 1.6 to 85.0], P = .03). Carriage of any of 3 coding NUDT15 variants was associated with an increased risk (OR, 27.3 [95% CI, 9.3 to 116.7], P = 1.1 × 10-7) of TIM, independent of TPMT genotype and thiopurine dose., Conclusions and Relevance: Among patients of European ancestry with IBD, variants in NUDT15 were associated with increased risk of TIM. These findings suggest that NUDT15 genotyping may be considered prior to initiation of thiopurine therapy; however, further study including additional validation in independent cohorts is required.

- Abstract
Pancreatitis occurs in approximately 4% of patients treated with the thiopurines azathioprine or mercaptopurine. Its development is unpredictable and almost always leads to drug withdrawal. We identified patients with inflammatory bowel disease (IBD) who had developed pancreatitis within 3 months of starting these drugs from 168 sites around the world. After detailed case adjudication, we performed a genome-wide association study on 172 cases and 2,035 controls with IBD. We identified strong evidence of association within the class II HLA region, with the most significant association identified at rs2647087 (odds ratio 2.59, 95% confidence interval 2.07-3.26, P = 2 × 10(-16)). We replicated these findings in an independent set of 78 cases and 472 controls with IBD matched for drug exposure. Fine mapping of the HLA region identified association with the HLA-DQA1*02:01-HLA-DRB1*07:01 haplotype. Patients heterozygous at rs2647087 have a 9% risk of developing pancreatitis after administration of a thiopurine, whereas homozygotes have a 17% risk.
