Abstract
BACKGROUND The management of inflammatory bowel disease (IBD) patients with concurrent liver transplantation is challenging, and data regarding the safety and efficacy of Janus kinase (JAK) inhibitors with anti-rejection medications are required. We report the experience of all liver transplant recipients receiving tofacitinib and/or upadacitinib for IBD across three states in Australia. METHODS All liver transplant recipients from the Australian states of Victoria, New South Wales and Tasmania who required tofacitinib or upadacitinib for the treatment of IBD were identified using prospectively maintained liver transplant databases. Patients were followed up until medication cessation or last follow up. Clinical safety and efficacy data were collected. RESULTS Eight patients (median age 30 years) were included, seven of whom received first-line JAK inhibition with tofacitinib. All patients had failed one or more biologic therapies prior to commencing JAK inhibition, including six patients who had failed two or more agents. JAK inhibition was continued for a median of 17 months, with 143 patient-months of combined follow-up. The anti-rejection medication tacrolimus was prescribed in all patients. Overall, seven (88%) patients achieved clinical remission, including all three patients who were switched from tofacitinib to upadacitinib. One patient required colectomy after 1 month of treatment. There were no other cases of serious infection, venous thromboembolism or major adverse cardiovascular events during follow-up. CONCLUSIONS As the largest case series to-date, these data indicate that combining JAK inhibition with transplant anti-rejection medication may be a safe and clinically effective method of treating IBD in patients with prior biologic failure.

Abstract
Acute severe ulcerative colitis (ASUC) is a distinctive ulcerative colitis flare presentation characterised by the presence of systemic inflammation as well as bloody diarrhoea, and occurs at least once in 25% of patients with ulcerative colitis during their disease course. Each episode carries a risk of complications, need for colectomy, and mortality. Little is known about ASUC pathogenesis, although impaired host-microbiota crosstalk involving pathobionts is suspected. In this Review, we discuss unanswered questions and results from the latest research on the medical-first-line, second-line, and potential third-line therapies-and surgical management of ASUC. We detail promising options for management, such as the use of enteral nutrition in combination with intravenous steroids, the ability to predict early failure of first-line or second-line therapies, and the emerging role of JAK inhibitors. An optimal framework to personalise therapy on the basis of multiomics tools is yet to be developed.

Abstract
OBJECTIVE We postulated that adalimumab [ADA] drug clearance [CL] may be a more critical determinant of therapeutic outcome than ADA concentration. This was tested in Crohn's disease [CD] patients undergoing ADA maintenance treatment. METHODS CD patients from four cohorts received ADA induction and started maintenance therapy. Therapeutic outcomes consisted of endoscopic remission [ER], sustained C-reactive protein [CRP] based clinical remission [defined as CRP levels below 3 mg/L in the absence of symptoms], and faecal calprotectin [FC] level below 100 µg/g. Serum albumin, ADA concentration, and anti-drug antibody status were determined using immunochemistry and homogeneous mobility shift assay, respectively. CL was determined using a nonlinear mixed effect model with Bayesian priors. Statistical analysis consisted of Mann-Whitney test and logistic regression with calculation of odds ratio. Repeated event analysis was conducted using a nonlinear mixed effect model. RESULTS In 237 enrolled patients [median age 40 years, 45% females], median CL was lower in patients achieving ER as compared with those with persistent active endoscopic disease [median 0.247 L/day vs 0.326 L/day, respectively] [p <0.01]. There was no significant difference in ADA concentration between patients in endoscopic remission compared with those with recurrence [median 9.3 µg/mL vs 11.7 µg/mL, respectively]. Sustained CRP-based clinical remission and FC levels below 100 µg/g were generally associated with lower CL and higher ADA concentration. Repeated event analysis confirmed those findings with better performances of CL than concentration in associating with ER and other outcomes. CONCLUSION Lower ADA clearance is associated with an improved clinical outcome for patients with Crohn's disease and may be a superior pharmacokinetic measure than concentration.

Abstract
Autophagy-related genes have been closely associated with intestinal homeostasis. BECLIN1 is a component of Class III phosphatidylinositol 3-kinase complexes that orchestrate autophagy initiation and endocytic trafficking. Here we show intestinal epithelium-specific BECLIN1 deletion in adult mice leads to rapid fatal enteritis with compromised gut barrier integrity, highlighting its intrinsic critical role in gut maintenance. BECLIN1-deficient intestinal epithelial cells exhibit extensive apoptosis, impaired autophagy, and stressed endoplasmic reticulum and mitochondria. Remaining absorptive enterocytes and secretory cells display morphological abnormalities. Deletion of the autophagy regulator, ATG7, fails to elicit similar effects, suggesting additional novel autophagy-independent functions of BECLIN1 distinct from ATG7. Indeed, organoids derived from BECLIN1 KO mice show E-CADHERIN mislocalisation associated with abnormalities in the endocytic trafficking pathway. This provides a mechanism linking endocytic trafficking mediated by BECLIN1 and loss of intestinal barrier integrity. Our findings establish an indispensable role of BECLIN1 in maintaining mammalian intestinal homeostasis and uncover its involvement in endocytic trafficking in this process. Hence, this study has important implications for our understanding of intestinal pathophysiology.

Abstract
BACKGROUND AND AIMS The risk of intrahepatic cholestasis of pregnancy (ICP) is increased in thiopurine exposed pregnancies. Thiopurine 'shunting', with a 6-methylmecrcaptopurine (MMP) to 6-thioguanine (TGN) ratio of >11, progresses over pregnancy, and may promote ICP development. We aimed to explore the association between thiopurine exposure and ICP, including the hypothesized impact of thiopurine shunting, and identify risk minimization strategies. METHODS This prospective multi-centre cohort study compared thiopurine and biologic monotherapy exposed pregnant participants. Disease activity and obstetric outcome data, thiopurine metabolites, bile acids and transaminases were obtained preconception, in each trimester, at delivery, and post-partum. Thiopurine dose management was at the discretion of the treating physician. RESULTS 131 thiopurine and 147 biologic monotherapy exposed pregnancies were included. MMP/TGN ratio increased from preconception to third trimester (p<0.01), with approximately 25% of participants shunting in pregnancy. Second trimester split-dosing led to a decrease in the median MMP/TGN ratio from 18 (IQR 6-57) to 3 (IQR 2-3.5) at delivery (p=0.04). The risk of ICP was increased in thiopurine exposed pregnancies (6.7% (7/105) vs 0% (0/112), p<0.001), with all ICP cases occurring in the setting of antenatal thiopurine shunting. Thiopurine dose increases (RR 8.10 [95% CI 1.88-34.85] p=0.005) and shunting in third trimester (6.20 [1.21-30.73] p=0.028) and at delivery (14.18 [1.62-123.9] p=0.016) were associated with an increased risk of ICP. CONCLUSIONS Thiopurine exposure is associated with an increased risk of ICP, particularly following dose increases antenatally and with shunting in late pregnancy. The latter may be effectively managed with split dosing, although further studies are warranted.

Abstract
BACKGROUND Despite reassuring clinical safety data, thrombocytosis, anemia, lymphopenia, and liver function derangements have been observed in infants born to women with inflammatory bowel disease (IBD) treated with thiopurines and biologics. We aimed to define the prevalence, course, associations, and clinical impact of hematological and biochemical abnormalities in such infants. METHODS This multicenter prospective cohort study assessed clinical, hematologic, and biochemical outcomes of infants exposed to thiopurines or biologics in utero for management of maternal IBD. Liver transaminases, full blood examination, and infant thiopurine metabolites (where exposed) were taken at delivery and 6 weeks of age. Abnormal results were repeated until normalization. Infants were followed clinically by a pediatric gastroenterologist up to 2 years of age. RESULTS A total of 130 infants were included. Thrombocytosis and elevated alanine transaminase (ALT) were seen in over half of infants up to 6 months of age with no significant clinical impact. Elevated ALT was associated with increasing maternal C-reactive protein in second trimester, while thrombocytosis was associated with increasing maternal C-reactive protein and fecal calprotectin in third trimester. Preceding infection and vaccination were associated with an increased risk of elevated alkaline phosphatase at 3 months. In those exposed to thiopurines, increasing maternal 6-methylmercaptopurine at delivery was associated with increased ALT to 6 months. CONCLUSIONS Infants born to women with IBD commonly developed thrombocytosis, elevated alkaline phosphatase, and elevated ALT. These findings were associated with exposure to maternal inflammation, elevated 6-methylmercaptopurine at delivery, and infant vaccinations and infections, and had minimal clinical consequence.

Abstract
BACKGROUND Thiopurines are established treatments for inflammatory bowel disease (IBD), yet concerns remain regarding their safety. AIM To evaluate the use of thiopurine-allopurinol combination therapy compared to standard thiopurine therapy in IBD. METHODS We performed a multicentre, randomised, placebo-controlled trial to compare the efficacy and safety of thiopurine-allopurinol versus thiopurine with placebo for adults commencing a thiopurine for IBD. Patients had active disease at baseline; dosing of therapy was based on a pre-specified regimen and subsequent metabolites. The primary outcome was the proportion of patients achieving a composite of symptomatic disease activity remission (Harvey Bradshaw Index <5 for Crohn's disease, Simple Clinical Colitis Activity Index <4 for ulcerative colitis) and a faecal calprotectin <150 μg/g after 26 weeks of treatment. RESULTS The trial was terminated early due to slow recruitment. We randomised 102 participants (54 thiopurine-allopurinol, 48 thiopurine with placebo) with similar age (median 42 vs 48 years) and sex distribution (46% women per group). A higher proportion achieved the primary outcome in the thiopurine-allopurinol group (50% vs 35%, p = 0.14) and fewer participants stopped their allocated therapy due to adverse events (11% vs 29%, p = 0.02). Also, within the thiopurine-allopurinol group, thiopurine dose adjustments were less frequent (69% vs 92%, p = 0.03), a higher proportion achieved an early therapeutic 6-TGN level at week 6 (71% vs 53%, p = 0.19), and adverse events attributed to therapy were less frequent (15% vs 44%, p = 0.002). CONCLUSION Thiopurine-allopurinol therapy is safe and mitigates thiopurine adverse effects, thus enhancing tolerability without compromising efficacy (ACTRN12613001347752).

Abstract
BACKGROUND Biologic drugs are highly effective for inflammatory bowel disease (IBD) management but are key drivers of costs of care especially when administered intravenously (i.v.). Availability of subcutaneous (SC) formulations has increased convenience for patients and improved access to care, but at the cost of revenue to health services. AIMS To evaluate the economic impact of transitioning a tertiary centre IBD cohort from i.v. to SC biologic administration and assess the implications for key stakeholders. METHODS A retrospective analysis of all patients who received i.v. infliximab or vedolizumab in the outpatient infusion centre of a tertiary IBD centre between July 2019 and June 2021 was undertaken. Data were collated from electronic medical records, pharmacy dispensing systems and the hospital business intelligence unit. An economic analysis and theoretical financial/capacity impact analysis of a transition to an SC model were estimated under two scenarios using a random 10% and 30% of the patient cohort. RESULTS Transitioning our IBD cohort from i.v. to SC administration would result in a loss to our health service of AU$2 732 123.75, composed of AU$1 463 003.75 in Weighted Inlier Equivalent Separation (WIES) and AU$1 269 120 in drug procurement revenue. However, it would ease capacity in the infusion centre by up to 5256 h. CONCLUSIONS Transitioning patients to SC administration results in improved access to infusion centres and substantial savings to state governments; however, switching results in a loss of i.v. biologic-generated WIES to health services. Alternative funding models are required to achieve sustainability in IBD care and reduce reliance on i.v. biologic-generated income.

Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) is an immune-mediated, chronic cholestatic liver disease. Currently, liver transplantation is the only established life-saving treatment. Several studies have evaluated the effect of different biologic therapies on PSC with inconclusive findings. We conducted a systematic review and meta-analysis to assess the effects of biologics in PSC and associated inflammatory bowel disease (IBD). METHODS MEDLINE, Scopus, and Embase were searched up to July 31, 2023, for studies reporting the effects of biologics in patients with PSC-IBD. Effects of biologic therapy on alkaline phosphatase, total bilirubin, ulcerative colitis response score, and adverse events were calculated and expressed as standardized difference of means (SMD), proportions, and 95% CI using a random-effects model. RESULTS Six studies, including 411 PSC-IBD patients who received biologics, were included. Biologic treatment was associated with no change in alkaline phosphatase (SMD: 0.1, 95% CI: -0.07 -0.17, p=0.43), but a small and statistically significant increase in total bilirubin (SMD: 0.2, 95% CI: 0.05-0.35, p<0.01). 31.2% (95% CI: 23.8-39.7) of patients with IBD achieved endoscopic response, and there was a significant improvement in ulcerative colitis response score (SMD: -0.6,95% CI: -0.88 to 0.36, p<0.01). Furthermore, 17.6% (95% CI: 13.0-23.5) of patients experienced adverse events severe enough to discontinue therapy, and 29.9% (95% CI: 25.2-34.8) had a loss of response to biologics. CONCLUSIONS Treatment of patients with PSC-IBD with biologics (vedolizumab, infliximab, and adalimumab) was not associated with improvement of biochemical markers of cholestasis. Biologics are effective in treating the colitis associated with PSC. Vedolizumab was associated with worsening liver enzymes in contrast to other biologics, a finding that warrants further study.

Abstract
Recent data, indicating that inflammatory bowel disease (IBD) may be a risk factor for future chronic kidney disease, highlight the need to study the safety and clinical effectiveness of advanced IBD therapies in patients with end stage renal disease (ESRD), defined as an eGFR <15 mL/min/1.73m2. Upadacitinib, a selective oral Janus kinase (JAK) 1 inhibitor, has demonstrated efficacy in the management of moderate to severe ulcerative colitis. There is also emerging data indicating that JAK inhibition may be clinically effective in the setting of steroid-refractory acute severe ulcerative colitis (ASUC). There is, however, a lack of "real-world" data documenting the use of JAK inhibitors in patients with ESRD. Here, we report the use of upadacitinib in a patient with ESRD for the management of steroid-refractory ASUC, demonstrating, for the first time, the safe and clinically effective use of upadacitinib in this population.

Abstract
BACKGROUND Acute severe ulcerative colitis (ASUC) is a medical emergency for which colectomy is required in patients who do not respond to rescue therapy. While previous studies have predominantly focused on predicting outcome to first-line corticosteroid therapy, there is a need to understand the factors associated with response to rescue therapies in order to improve clinical outcomes. We reviewed the evidence regarding factors associated with response to rescue therapy in adults with ASUC and identified future directions for research. METHODS A systematic search of the literature was conducted, and 2 reviewers independently assessed studies for inclusion. RESULTS Of 3509 records screened, 101 completed studies were eligible for inclusion. We identified 42 clinical, hematological, biochemical, endoscopic, or pharmacological factors associated with response to rescue therapy. Older age (≥50 years), thiopurine experience, and cytomegalovirus or Clostridioides difficile infection were associated with a higher risk of nonresponse to rescue therapy. Biochemical factors associated with poorer response included an elevated C-reactive protein (CRP) ≥30mg/L on admission, hypoalbuminemia and an elevated ratio of CRP to albumin. Severe endoscopic findings, including a Mayo endoscopic score of 3 or Ulcerative Colitis Endoscopic Index of Severity ≥5, portended poorer outcomes. The role of fecal calprotectin and therapeutic value of measuring infliximab drug levels in ASUC remain to be defined. CONCLUSIONS Response to rescue therapy can be predicted by several specific factors, which would aid clinical decision-making. Existing and emerging factors should be integrated within predictive and prognostic models to help improve clinical outcomes.

Abstract
The Crohn's Disease Exclusion Diet (CDED) with partial enteral nutrition (PEN) is an emerging treatment option for Crohn's disease (CD). A 35-year-old pregnant woman presented with newly diagnosed ileal CD. At 14/40 gestation, CDED + PEN was prescribed without drug therapy. Outcomes included Harvey-Bradshaw Index, weight, and bowel wall thickness/Limberg score measured on intestinal ultrasound (IUS). In this patient, CDED + PEN achieved clinical and biochemical remission, improvements on IUS, gestational weight gain, and healthy birth weight without drug therapy. Sustained remission was achieved postpartum. Our case highlights the potential effectiveness of CDED + PEN to induce remission for active CD during pregnancy.

Abstract
BACKGROUND The modified Rutgeerts' score [RS] differentiates i2a-lesions confined to the anastomosis-and i2b-more than five aphthous ulcers in the neoterminal ileum with normal intervening mucosa, with or without anastomotic lesions-categories. Its relevance for the therapeutic management of Crohn's disease [CD] patients after ileocolic resection is still debated. Our objective was to compare the postoperative recurrence risk in patients with an i2a or i2b score, using an individual patient data meta-analysis. METHODS We conducted a systematic literature search until July 2020, to identify all relevant studies reporting the i2a/i2b status in the year following ileocolic resection and clinical and/or surgical postoperative CD recurrence in their follow-up. Individual patient-level data were obtained from the corresponding authors. The association between the modified RS and time-to-event was evaluated using a mixed Cox model with the centre as the random effect. RESULTS Seven studies published between 2008 and 2019 were included, corresponding to 400 patients: 189 [47%] i2a and 211 [53%] i2b. Median [interquartile range, IQR] time from ileocolic resection to ileocolonoscopy was 6.2 [5.5, 7.9] months and median [IQR] follow-up time after ileocolonoscopy was 4.5 [2.9, 7.3] years. The risk of clinical postoperative recurrence at 1 and 3 years was 11% [6-15%], and 25% [18-32%] in the i2a group versus 9% [5-13%] and 33% [26-41%] in the i2b group [p = 0.63 and p = 0.12, respectively]. No significant difference was observed in terms of time to clinical postoperative recurrence [p = 0.16] or surgical postoperative recurrence [p = 0.87]. Results did not change after excluding patients having initiated an immunosuppressant or a biologic in the 3 months after endoscopy [remaining cohort, n = 361]. CONCLUSIONS In this individual patient data meta-analysis, no difference was observed between i2a and i2b subcategories with regards to clinical or surgical postoperative recurrence. As we wait for prospective trials, the same treatment strategy could be applied to all patients classified as i2 on the Rutgeerts score.

Abstract
The cost of caring for patients with inflammatory bowel disease (IBD) continues to increase worldwide. The cause is not only a steady increase in the prevalence of Crohn's disease and ulcerative colitis in both developed and newly industrialised countries, but also the chronic nature of the diseases, the need for long-term, often expensive treatments, the use of more intensive disease monitoring strategies, and the effect of the diseases on economic productivity. This Commission draws together a wide range of expertise to discuss the current costs of IBD care, the drivers of increasing costs, and how to deliver affordable care for IBD in the future. The key conclusions are that (1) increases in health-care costs must be evaluated against improved disease management and reductions in indirect costs, and (2) that overarching systems for data interoperability, registries, and big data approaches must be established for continuous assessment of effectiveness, costs, and the cost-effectiveness of care. International collaborations should be sought out to evaluate novel models of care (eg, value-based health care, including integrated health care, and participatory health-care models), as well as to improve the education and training of clinicians, patients, and policy makers.

Abstract
BACKGROUND The optimal infliximab dose intensification strategy to address secondary loss of response (LOR) remains unclear. This study aimed to compare clinical and pharmacokinetic outcomes following (i) upfront infliximab re-induction with (ii) ongoing 6-weekly dose interval shortening (DIS), after the same number of doses. METHODS A prospective parallel cohort study of inflammatory bowel disease patients who required infliximab dose intensification for secondary LOR using (i) re-induction (i.e., repeat 5 mg/kg 0, 2, 6-week dosing) followed by 8-weekly maintenance or (ii) 6-weekly 5 mg/kg DIS was undertaken. Week 32 clinical response was the primary outcome, with secondary evaluation of infliximab pharmacokinetics and predictors of response. RESULTS Of 104 patients, 54 underwent re-induction, and 50 underwent 6-weekly DIS; 43 per cohort had clinically active disease, with comparable baseline infliximab levels (2.03 vs 2.02 ug/mL, P = 0.83). Clinical response was similar across re-induction and DIS cohorts at weeks 12 (69.8 vs 65.1%) and 32 (53.5 vs 62.8%, each P > 0.50); however, both strategies demonstrated distinct pharmacokinetic profiles at weeks 6 (18.45 vs 5.36 ug/mL, P < 0.01), 12 (8.94 vs 5.96 ug/mL, P = 0.02) and 30 (3.89 vs 6.35 ug/mL, P = .0.02). In multivariable analyses, objectively verified active disease at baseline (OR 12.92, 95% CI [1.84-90.84], P = 0.01), subtherapeutic week 6 infliximab levels (OR 0.12, 95% CI [0.01, 0.99], P = 0.049) and week 12 clinical response (OR 5.44, 95% CI [1.20-19.97], P = 0.04) were associated with week 32 response, as were week 2 infliximab levels (OR 1.34, 95% CI [1.02-1.47], P = 0.04) following re-induction. Following re-induction, week 2 infliximab levels <15.6 ug/mL (AUROC 0.76, 95% CI [0.54-0.99], P < 0.05) predicted nonresponse at week 32. CONCLUSION Dose intensification strategy impacted immediate and sustained infliximab levels but not clinical response. Upfront intensification was associated with short-term pharmacokinetic advantages, including predictors of response, that diminished with time. Hence, when applying upfront dose intensification, clinicians should consider continuing intensified dosing to sustain early pharmacokinetic advantages based on predictors of (non)response.

Abstract
BACKGROUND The lack of standardized methods for clinical trial design and disease activity assessment has contributed to an absence of approved medical therapies for the prevention of postoperative Crohn's disease (CD). We developed recommendations for regulatory trial design for this indication and for endoscopic assessment of postoperative CD activity. METHODS An international panel of 19 gastroenterologists was assembled. Modified Research and Development/University of California Los Angeles methodology was used to rate the appropriateness of 196 statements using a 9-point Likert scale in 2 rounds of voting. Results were reviewed and discussed between rounds. RESULTS Inclusion of patients with a history of completely resected ileocolonic CD in regulatory clinical trials for the prevention of postoperative recurrence was appropriate. Given the absence of approved medical therapies, a placebo-controlled design with a primary end point of endoscopic remission at 52 weeks was appropriate for drug development for this indication; however, there was uncertainty regarding the appropriateness of a coprimary end point of symptomatic and endoscopic remission and the use of currently available patient-reported outcome measures. The modified Rutgeerts Score, endoscopic assessment of the anastomosis, and a minimum of 5cm of neoterminal ileum were also appropriate; although the appropriateness of other indices including the Simple Endoscopic Score for CD for endoscopic assessment of postoperative CD activity was uncertain. CONCLUSIONS A framework for regulatory trial design for the prevention of postoperative CD recurrence and endoscopic assessment of disease activity has been developed. Research to empirically validate end points for these trials is needed.

Abstract
INTRODUCTION Crohn's disease recurs after intestinal resection. This study evaluated accuracy of a new blood test, the Endoscopic Healing Index [EHI], in monitoring for disease recurrence. METHODS Patients enrolled in the prospective POCER study [NCT00989560] underwent a postoperative colonoscopic assessment at 6 [2/3 of patients] and 18 months [all patients] following bowel resection, using the Rutgeerts score [recurrence ≥i2]. Serum was assessed at multiple time points for markers of endoscopic healing using the EHI, and paired with the Rutgeerts endoscopic score as the reference standard. RESULTS A total of 131 patients provided 437 serum samples, which were paired with endoscopic assessments available in 94 patients [30 with recurrence] at 6 months and 107 patients [44 with recurrence] at 18 months. The median EHI at 6 months was significantly lower in patients in remission [Rutgeerts <i2] than those with recurrence; p = 0.033. The area under the receiver operating curve [AUROC] for EHI to detect recurrence at 6 months was comparable to that of faecal calprotectin [0.712 vs 0.779, p = 0.414]. EHI of <20 at 6 months had a negative predictive value of 75.7% (95% confidence interval [CI] 58.8-88.2), and sensitivity of 70% [95% CI 50.6-85.3] for detecting recurrence. Combining all time points, an EHI <20 had a negative predictive value of 70.3%. Changes in EHI significantly associated with changes in Rutgeerts scores over the 18 months. CONCLUSIONS The non-invasive multi-marker EHI has sufficient accuracy to be used to monitor for postoperative Crohn's disease recurrence. A monitoring strategy that combines EHI with ileocolonoscopy, with or without faecal calprotectin, should now be prospectively tested.

Abstract
BACKGROUND & AIMS Higher anti-tumor necrosis factor-α (TNF) drug levels are associated with improved clinical healing of Crohn's perianal fistulas. It is unclear whether this leads to improved healing on radiologic assessment. We aimed to evaluate the association between anti-TNF drug levels and radiologic outcomes in perianal fistulising Crohn's disease. METHODS A cross-sectional retrospective multicenter study was undertaken. Patients with perianal fistulising Crohn's disease on maintenance infliximab or adalimumab, with drug levels within 6 months of perianal magnetic resonance imaging were included. Patients receiving dose changes or fistula surgery between drug level and imaging were excluded. Radiologic disease activity was scored using the Van Assche Index, with an inflammatory subscore calculated using indices: T2-weighted imaging hyperintensity, collections >3 mm diameter, rectal wall involvement. Primary endpoint was radiologic healing (inflammatory subscore ≤6). Secondary endpoint was radiologic remission (inflammatory subscore = 0). RESULTS Of 193 patients (infliximab, n = 117; adalimumab, n = 76), patients with radiologic healing had higher median drug levels compared with those with active disease (infliximab 6.0 vs 3.9 μg/mL; adalimumab 9.1 vs 6.2 μg/mL; both P < .05). Patients with radiologic remission also had higher median drug levels compared with those with active disease (infliximab 7.4 vs 3.9 μg/mL; P < .05; adalimumab 9.8 vs 6.2 μg/mL; P = .07). There was a significant incremental reduction in median inflammatory subscores with higher anti-TNF drug level tertiles. CONCLUSIONS Higher anti-TNF drug levels were associated with improved radiologic outcomes on magnetic resonance imaging in perianal fistulising Crohn's disease, with an incremental improvement at higher drug level tertiles for both infliximab and adalimumab.

Abstract
BACKGROUND The presence and severity of endoscopic recurrence after Crohn's disease intestinal resection predicts subsequent disease course. The Rutgeerts postoperative endoscopic recurrence score is unvalidated but has proven prognostically useful in many clinical studies. This study aimed to investigate the association between specific early endoscopic findings and subsequent disease course. METHODS In the setting of a randomized controlled trial (the POCER study), 85 patients underwent colonoscopy at 6 and 18 months after intestinal resection. Patients received 3 months of metronidazole, and high-risk patients received a thiopurine (or adalimumab if they were thiopurine intolerant). For endoscopic recurrence (Rutgeerts score ≥i2) at 6 months, patients stepped up to a thiopurine, fortnightly adalimumab with thiopurine, or weekly adalimumab. Central readers confirmed Rutgeerts, Simple Endoscopic Score for Crohn's Disease, Crohn's Disease Endoscopic Index of Severity scores, and 5 newly tested endoscopic parameters: anastomotic ulcer depth (superficial vs deep), number of ulcers (0, ≤2, >2), ulcer size (1-5 mm, ≥6 mm), circumferential extent of ulceration (<25%, ≥25%), and the presence or absence of stenosis. The POCER index, based on the 6-month postoperative findings, was then developed in relation to predicting the endoscopic outcome at 18 months. RESULTS Of the 5 parameters, the combination of ulcer depth and circumference at the anastomosis at 6 months was associated with endoscopic recurrence at 18 months (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.03-2.50; P = 0.035) with an area under the receiver operating characteristic curve of 0.62 (95% CI, 0.5-0.75). The combination of these 2 parameters formed the basis of the POCER index (range, 0-4 with 0 denoting no ulcers and 4 denoting deep ulceration with >25% circumferential involvement). The new index had a strong correlation with the Rutgeerts score measured at the same time points: Spearmans' r = .80 at 6 months and r = .77 at 18 months (P < 0.001 at both time points). A POCER index of ≥2 and a Rutgeerts score of ≥i2 both had a sensitivity of 0.41 for recurrence; however, the POCER index had a higher specificity (0.8 and 0.67, respectively). The POCER index at 6 months was associated with endoscopic recurrence at 18 months (OR, 1.5; 95% CI, 1.2-2.0; P = 0.002; area under the receiver operating characteristic curve of 0.70; 95% CI, 0.57-0.82), but the Rutgeerts score was not (OR, 1.2; 95% CI, 0.8-1.8; P = 0.402). CONCLUSIONS The POCER postoperative index comprises 2 key endoscopic factors related to the anastomosis that are associated with subsequent disease progression. A higher score, comprising the adverse prognostic factors of deep or circumferentially extensive anastomotic ulceration, may help identify patients who require more intensive therapy.

Abstract
INTRODUCTION Anti-tumor necrosis factor (TNF) dose intensification represents an effective method of overcoming secondary loss of response (LOR); however, a subset of patients may not respond (tertiary non-response), or fail to demonstrate durable response (tertiary LOR) to intensified dosing. This systematic review and meta-analysis aimed to evaluate these outcomes to determine the clinical effectiveness of empiric dose intensification in Crohn's disease. METHODS Multiple databases including MEDLINE and EMBASE were interrogated to identify studies that reported outcomes following anti-TNF dose intensification to address secondary LOR in Crohn's disease. Studies that used anti-TNF levels as the primary basis for dose intensification were excluded. Studies that reported (1) tertiary response and tertiary non-response within 6 months or (2) tertiary response and tertiary LOR beyond 6 months, were pooled using a random effects model with risk ratio (RR) derived, quantifying the effect of each comparison. RESULTS Twenty-six studies reported outcomes following anti-TNF dose intensification to address secondary LOR. Short-term response within 12 weeks of any dose-intensification strategy was 33-90%, while sustained response (⩾48 weeks) was achieved in 25-85%. Tertiary non-response occurred in up to 45% of intensified patients within 6 months of anti-TNF dose intensification, while tertiary LOR beyond 6 months occurred in up to 64% of patients. Tertiary response was more likely than tertiary non-response within 6 months (RR 2.58, 95% CI (1.76, 3.79), I 2 = 82%, 12 studies), while sustained response beyond 6 months compared to tertiary LOR (RR 1.10 (0.75, 1.61) I 2 = 85%, 7 studies) was less convincing. CONCLUSION Although anti-TNF dose intensification is clinically effective in patients with Crohn's disease, particularly within the first 6 months, a proportion of patients will fail to demonstrate short-term and/or sustained clinical response. Hence, clinical reassessment following anti-TNF dose intensification, particularly beyond 6 months, remains important to differentiate between effective and ineffective dose-intensification strategies.

Abstract
BACKGROUND AND AIMS Preliminary data regarding the effectiveness of tofacitinib in acute severe ulcerative colitis [ASUC] have been presented in two previous case series. We aimed to describe the novel use of high-dose tofacitinib immediately following non-response to infliximab in the setting of steroid-refractory ASUC. METHODS Five patients who received high-dose tofacitinib 10 mg three times a day immediately following non-response to infliximab for steroid-refractory ASUC were identified at an Australian tertiary inflammatory bowel disease centre. RESULTS Four of the five patients demonstrated clinical response to high-dose tofacitinib induction during their inpatient admission, with one patient requiring colectomy owing to a lack of clinical response. At 90 days, all four initial responders remained colectomy-free, with two patients achieving combined clinical and endoscopic remission. No adverse events directly attributable to high-dose tofacitinib were identified. CONCLUSIONS High-dose tofacitinib may have a role as salvage therapy in the setting of steroid-refractory ASUC. Prospective studies are required to determine the safety and efficacy of high-dose tofacitinib to determine whether it can be routinely recommended as primary or sequential salvage therapy in the setting of steroid-refractory ASUC.

Abstract
BACKGROUND AND AIMS In symptomatic patients with ileoanal pouches, pouchoscopy is needed for accurate diagnosis but is invasive. We aimed to assess the utility of non-invasive gastrointestinal ultrasound and faecal calprotectin in ileoanal pouch patients. METHODS Patients with an ileoanal pouch were consecutively enrolled in this cross-sectional study from clinics in Victoria, Australia. The pouchitis disease activity index was used as a reference standard. Video-recorded pouchoscopies were reviewed by three gastroenterologists. Pouch, pre-pouch, and cuff biopsies were reviewed by a single pathologist. Ultrasound was performed by a single gastroenterologist transabdominally and transperineally. Faecal calprotectin was measured from morning stool samples. All examiners were blinded to patients' clinical history. RESULTS A total of 44 participants had a pouchoscopy, of whom 43 had a faecal calprotectin test and 42 had an ultrasound; 17 had pouchitis, 15 had pre-pouch ileitis, and 16 had cuffitis. Pouch wall thickness of <3 mm was 88% sensitive in excluding pouchitis, and pouch wall thickness of ≥4 mm was 87% specific in diagnosing pouchitis. Transabdominal ultrasound had good utility [area under the curve: 0.78] in diagnosing moderate-severe pre-pouch ileitis. Transperineal ultrasound had good utility for the diagnosis of pouchitis [area under the curve: 0.79]. Faecal calprotectin differentiated inflammatory from non-inflammatory pouch disorders, such as irritable pouch syndrome, with an area under the curve of 0.90. Faecal calprotectin <100 µg/g ruled out inflammatory pouch disorders with a sensitivity of 94%. CONCLUSIONS Faecal calprotectin and ultrasound are accurate and complementary tests to diagnose and localise inflammation of the ileoanal pouch. Prospective studies are needed to validate proposed sonographic indices and calprotectin levels.

Abstract
BACKGROUND AND AIMS Currently used endoscopic items for the assessment of pouchitis and cuffitis have deficiencies in reliability and validation. We assessed the reliability and accuracy of new endoscopic items for pouchitis and of the Ulcerative Colitis Endoscopic Index of Severity [UCEIS] for cuffitis. METHODS Three new endoscopic items were assessed and included in the Monash pouchitis endoscopic subscore: bleeding [absent/contact/spontaneous]; erosions [absent/<10/≥10]; and ulceration [absent/<10%/≥10%]. Three raters evaluated 44 pouchoscopy videos in duplicates, in random order. Intra- and inter-rater reliability of all endoscopic items and UCEIS were assessed. Clinical and histological pouchitis disease activity index [PDAI] subscores were also assessed and faecal calprotectin was measured. RESULTS All three Monash endoscopic items had substantial intra-rater reliability with intraclass correlation coefficients [ICCs] >0.61 [95% CI >0.61], compared with only ulcers from the currently used PDAI endoscopic subscore, but inter-rater reliability was only substantial for ulceration and no better than those of the currently used endoscopic items. The Monash endoscopic subscore had a strong positive correlation with the reference standard global endoscopic lesion severity r = 0.80 [95% CI 0.80-0.80] and the reference standard PDAI endoscopic subscore r = 0.70 [95% CI 0.67-0.73], which was higher than the correlation observed for the currently used PDAI endoscopic subscore. The UCEIS had substantial intra-rater reliability, but only fair inter-rater reliability and poor diagnostic performance for cuffitis. CONCLUSIONS The Monash endoscopic items, and endoscopic subscore they generate, have enhanced overall performance compared with the currently used PDAI items and subscore. Further validation and responsiveness to change in disease state are indicated.

Abstract
BACKGROUND Strictures are the most common structural complication of Crohn's disease. Surgery and endoscopic balloon dilation are the main treatments; drug therapy has been considered contraindicated. Given that most strictures have an inflammatory component, we aimed to find out whether strictures are responsive to drug treatment and whether intensive drug therapy is more effective than standard drug therapy. METHODS This open-label, single-centre, randomised controlled trial was performed in one specialist inflammatory bowel disease centre in Australia. Patients aged 18 years or older with Crohn's disease were included. Eligible patients had a de novo or postoperative anastomotic intestinal stricture on MRI or ileocolonoscopy, symptoms consistent with chronic or subacute intestinal obstruction (postprandial abdominal pain in the presence of a confirmed stricture), and evidence of active intestinal inflammation. Patients were randomly assigned (2:1) to receive intensive high-dose adalimumab (160 mg adalimumab once per week for 4 weeks followed by 40 mg every 2 weeks, with escalation of dose at 4 months and 8 months if assessment of disease activity indicated active inflammation) plus thiopurine (initial dose of azathioprine 2·5 mg/kg or mercaptopurine 1·5 mg/kg, with dose adjustment based on thiopurine metabolite testing) or standard adalimumab monotherapy (160 mg at week 0, 80 mg at week 2, then 40 mg every 2 weeks) using stratified fixed block randomisation. Stratification factors were stricture dilation at study baseline colonoscopy and current biologic drug use. The primary endpoint was improvement (decrease) in the 14-day obstructive symptom score at 12 months by one or more points compared with baseline. This trial is registered with ClinicalTrials.gov, NCT03220841, and is completed. FINDINGS Between Sept 10, 2017, and Sept 6, 2019, 123 patients were screened and 77 randomly assigned to intensive adalimumab plus thiopurine treatment (n=52) or standard adalimumab treatment (n=25). At 12 months, improvement in obstructive symptom score was noted in 41 (79%) of 52 patients in the intensive treatment group and 16 (64%) of 25 in the standard treatment group (odds ratio [OR] 2·10 [95% CI 0·73-6·01]; p=0·17). Treatment failure occurred in five (10%) patients in the intensive treatment group versus seven (28%) in the standard treatment group (OR 0·27 [95% CI 0·08-0·97]; p=0·045); four patients in each group required stricture surgery (0·44 [0·10-1·92]; p=0·27). Crohn's Disease Activity Index was less than 150 in 36 (69%) patients in the intensive treatment group versus 15 (60%) in the standard treatment group (1·50 [0·56-4·05]; p=0·42). MRI at 12 months showed improvement using the stricture MaRIA score (≥25%) in 31 (61%) of 51 versus seven (28%) of 25 patients (3·99 [1·41-11·26]; p=0·0091). MRI complete stricture resolution was seen in ten (20%) versus four (16%) patients (1·28 [0·36 to 4·57]; p=0·70). Intestinal ultrasound at 12 months showed improvement (>25%) in bowel wall thickness in 22 (51%) of 43 versus seven (33%) of 21 patients (2·10 [0·71 to 6·21]; p=0·18). Faecal calprotectin normalised in 32 (62%) versus 11 (44%) patients (2·04 [0·77-5·36]; p=0·15). Normalisation of CRP was seen in 32 (62%) versus 11 (44%) patients (2·04 [0·77-5·36]; p=0·15). Eight (15%) patients in the intensive treatment group and four (16%) in the standard treatment group reported serious adverse events. No deaths occurred during the study. INTERPRETATION Crohn's disease strictures are responsive to drug treatment. Most patients had improved symptoms and stricture morphology. Treat-to-target therapy intensification resulted in less treatment failure, a reduction in stricture-associated inflammation, and greater improvement in stricture morphology, although these differences were not significantly different from standard therapy.

Abstract
BACKGROUND There is considerable interest in improving the education and care of women with inflammatory bowel disease (IBD) to improve pregnancy outcomes. Despite increased awareness, not all women with IBD have access to pregnancy-related education and the quality of counseling is variable. We aimed to assess the effectiveness of a simple educational intervention for improving pregnancy-related knowledge and to evaluate the effect of education on patient outcomes including anxiety, depression, and quality of life in women with IBD. METHODS This prospective study of women with IBD who were pregnant or planning a pregnancy evaluated the effectiveness of a single gastroenterologist-led educational intervention in improving pregnancy-related knowledge, measured using the Crohn's and Colitis Pregnancy Knowledge score 1 month postintervention. Secondary outcomes included the effect on anxiety and depression, quality of life, medication adherence, and patient satisfaction. RESULTS One hundred women with IBD were recruited. Fifty percent were pregnant at the time of the intervention. Baseline knowledge scores were similar independent of the patients' pregnancy status or whether they had previously received counseling from their gastroenterologist. Median Crohn's and Colitis Pregnancy Knowledge scores postintervention (n = 82) were higher than preintervention scores (14/17 vs 10/17; P < 0.001). In addition, 32% of patients had poor knowledge at baseline (score ≤7/17), compared to only 5% after the intervention (P < 0.001). There was a significant improvement in total anxiety and depression and quality of life scores postintervention. Medication adherence and patient satisfaction were excellent. CONCLUSIONS Uptake of this gastroenterologist-led educational intervention has the potential to improve pregnancy knowledge, promote medication adherence, and enhance quality of life for women with IBD globally.

Abstract
BACKGROUND Azathioprine and mercaptopurine are considered safe during pregnancy. However, the pharmacokinetic effects of pregnancy on thiopurine metabolism are undefined. AIMS To characterise thiopurine metabolism in pregnancy and measure infant metabolite levels and outcomes. METHODS Women with IBD who were taking a thiopurine and pregnant or trying to conceive were recruited. Maternal thiopurine metabolites were measured pre-conception, in each trimester, at delivery and post-partum. Infant metabolite levels, full blood examination and liver function testing were performed at birth, and repeated until levels undetectable and haematological and biochemical abnormalities resolved. RESULTS Forty patients were included with measurements on at least two occasions, and two with only mother-baby levels at delivery. The median maternal 6-TGN level dropped in the second trimester compared with post-partum (179.0 vs 323.5 pmol/8 × 108 RBCs, P < 0.001) and the median 6-MMP level increased in the second trimester compared with post-partum (1103.0 vs 329.5 pmol/8 × 108 RBCs, P < 0.01). At delivery, the median 6-TGN level was lower in infants (n = 20) than mothers (78.5 vs 217 pmol/8 × 108 RBCs) (P < 0.001). Metabolites were not detected at 6 weeks in any infants. Anaemia was not seen, but thrombocytosis and abnormal liver biochemistry were detected in 80% of infants from 6 weeks, which gradually improved. CONCLUSIONS 6-TGN levels decrease and 6-MMP levels increase in the second trimester of pregnancy. Infants are exposed to thiopurine metabolites at low levels with clearance by 6 weeks and no anaemia. The cause of infant thrombocytosis and abnormal liver biochemistry in the absence of metabolites is unclear.

Abstract
Background Shared decision making (SDM) is becoming an important part of ulcerative colitis (UC) management because of the increasing complexity of available treatment choices and their trade-offs. The use of decision aids (DA) may be effective in increasing patients’ participation in UC management but their uptake has been limited due to high attrition rates and lack of a participatory approach to their design and implementation. Objective The primary aim of this study is to explore the perspectives of Australian patients and their clinicians regarding the feasibility and acceptability of myAID, a web-based DA, in informing treatment decisions in UC. The secondary aim is to use the findings of this pilot study to inform the design of a cluster randomized clinical trial (CRCT) to assess the efficacy of the DA compared with usual care. Methods myAID, a DA was designed and developed using a participatory approach by a multidisciplinary team of clinicians, patients, and nonmedical volunteers. A qualitative pilot study to evaluate the DA, involving patients with UC facing new treatment decisions and inflammatory bowel disease clinicians, was undertaken. Results A total of 11 patients with UC and 15 clinicians provided feedback on myAID. Themes explored included the following: Acceptability and usability of myAID—myAID was found to be acceptable by the majority of clinicians as a tool to facilitate SDM, uptake was thought to vary depending on clinicians’ approaches to patient education and practice, potential to overcome time restrictions associated with outpatient clinics was identified, presentation of unbiased information enabling patients to digest information at their own pace was noted, and potential to provoke anxiety among patients with a new diagnosis or mild disease was raised; Perceived role and usefulness of myAID—discordance was observed between patients who prioritized voicing preferences and clinicians who prioritized treatment adherence, and myAID facilitated early discussion of medical versus surgical treatment options; Target population and timing of use—greatest benefit was perceived at the time of initiating or changing treatment and following commencement of immunosuppressive therapy; and Potential concerns and areas for improvement—some perceived that use of myAID may precipitate anxiety by increasing decisional conflict and impact the therapeutic relationship between patient and the clinician and may increase resource requirements. Conclusions These preliminary findings suggest that patients and clinicians consider myAID as a feasible and acceptable tool to facilitate SDM for UC management. These pilot data have informed a participatory approach to the design of a CRCT, which will evaluate the clinical efficacy of myAID compared with usual care.

Abstract
BACKGROUND The impact of inflammatory bowel disease (IBD) activity on long-term outcomes after liver transplantation (LT) for primary sclerosing cholangitis (PSC) is unknown. We examined the impact of post-LT IBD activity on clinically significant outcomes. METHODS One hundred twelve patients undergoing LT for PSC from 2 centers were studied for a median of 7 years. Patients were divided into 3 groups according to their IBD activity after LT: no IBD, mild IBD, and moderate to severe IBD. Patients were classified as having moderate to severe IBD if they met at least 1 of 3 criteria: (i) Mayo 2 or 3 colitis or Simple Endoscopic Score-Crohn's Disease ≥7 on endoscopy; (ii) acute flare of IBD necessitating steroid rescue therapy; or (iii) post-LT colectomy for medically refractory IBD. RESULTS Moderate to severe IBD at any time post-transplant was associated with a higher risk of Clostridium difficile infection (27% vs 8% mild IBD vs 8% no IBD; P = 0.02), colorectal cancer/high-grade dysplasia (21% vs 3% both groups; P = 0.004), post-LT colectomy (33% vs 3% vs 0%) and rPSC (64% vs 18% vs 20%; P < 0.001). Multivariate analysis revealed that moderate to severe IBD increased the risk of both rPSC (relative risk [RR], 8.80; 95% confidence interval [CI], 2.81-27.59; P < 0.001) and colorectal cancer/high-grade dysplasia (RR, 10.45; 95% CI, 3.55-22.74; P < 0.001). CONCLUSIONS Moderate to severe IBD at any time post-LT is associated with a higher risk of rPSC and colorectal neoplasia compared with mild IBD and no IBD. Patients with no IBD and mild IBD have similar post-LT outcomes. Future prospective studies are needed to determine if more intensive treatment of moderate to severe IBD improves long-term outcomes in patients undergoing LT for PSC.

Abstract
BACKGROUND The impact of pregnancy on levels of biologic agents in patients with IBD is undefined and time to elimination in vedolizumab-exposed infants is unknown. AIMS To determine the effect of pregnancy on infliximab, adalimumab and vedolizumab levels and to study infant vedolizumab clearance METHODS: In a prospective observational study, maternal drug levels were measured pre-conception, in each trimester, at delivery and postpartum. The association between drug levels and gestation in weeks was assessed using generalised estimating equation modelling. Infant vedolizumab levels were performed at birth (cord blood), 6 weeks and 3 months or until undetectable. RESULTS We included 50 IBD patients (23 on infliximab, 15 on adalimumab and 12 on vedolizumab) with at least two intrapartum observations, plus 5 patients on vedolizumab with only mother and baby samples at delivery. Modelling showed no change in adalimumab levels, an increase in infliximab levels of 0.16 (95% CI 0.08-0.24) µg/L/week (P < 0.001) and a decrease of 0.18 (95% CI: -0.33 to -0.02) µg/L/week (P = 0.03) for vedolizumab. In 17 mother-baby pairs, median infant vedolizumab levels at birth were lower than maternal levels (P < 0.05) with an infant:maternal ratio of 0.7 (IQR 0.5-0.9). Vedolizumab was undetectable between 15 and 16 weeks of age in all 12 infants completing follow-up testing. CONCLUSIONS During pregnancy, adalimumab levels remain stable, while infliximab levels increase and vedolizumab levels decrease. However, the increments were small suggesting that intrapartum therapeutic drug monitoring and dose adjustment are not indicated. Unlike infliximab and adalimumab, infant vedolizumab levels are lower in cord blood than in mothers and appear to clear rapidly.

Abstract
BACKGROUND Microbial factors are likely to be involved in the recurrence of Crohn's disease (CD) after bowel resection. We investigated the luminal microbiota before and longitudinally after surgery, in relation to disease recurrence, using 16S metagenomic techniques. METHODS In the prospective Post-Operative Crohn's Endoscopic Recurrence (POCER) study, fecal samples were obtained before surgery and 6, 12, and 18 months after surgery from 130 CD patients. Endoscopy was undertaken to detect disease recurrence, defined as Rutgeerts score ≥i2, at 6 months in two-thirds of patients and all patients at 18 months after surgery. The V2 region of the 16S rRNA gene was sequenced using Illumina MiSeq. Cluster analysis was performed at family level, assessing microbiome community differences between patients with and without recurrence. RESULTS Six microbial cluster groups were identified. The cluster associated with maintenance of remission was enriched for the Lachnospiraceae family [adjusted OR 0.47 (0.27-0.82), P = .007]. The OTU diversity of Lachnospiraceae within this cluster was significantly greater than in all other clusters. The cluster enriched for Enterobacteriaceae was associated with an increased risk of disease recurrence [adjusted OR 6.35 (1.24-32.44), P = .026]. OTU diversity of Enterobacteriaceae within this cluster was significantly greater than in other clusters. CONCLUSIONS Luminal bacterial communities are associated with protection from, and the occurrence of, Crohn's disease recurrence after surgery. Recurrence may relate to a higher abundance of facultatively anaerobic pathobionts from the Enterobacteriaceae family. The ecologic change of depleted Lachnospiraceae, a genus of butyrate-producing bacteria, may permit expansion of Enterobacteriaceae through luminal environmental perturbation.

Abstract
BACKGROUND Vedolizumab (VDZ), a humanised monoclonal antibody that selectively inhibits alpha4-beta7 integrins is approved for use in adult moderate to severe ulcerative colitis (UC) patients.
AIM To assess the efficacy and safety of VDZ in the real-world management of UC in a large multicenter cohort involving two countries and to identify predictors of achieving remission.
METHODS A retrospective review of Australian and Oxford, United Kingdom data for UC patients. Clinical response at 3 mo, endoscopic remission at 6 mo and clinical remission at 3, 6 and 12 mo were assessed. Cox regression models and Kaplan Meier curves were performed to assess the time to remission, time to failure and the covariates influencing them. Safety outcomes were recorded.
RESULTS Three hundred and three UC patients from 14 centres in Australia and United Kingdom, [60% n = 182, anti-TNF naïve] were included. The clinical response was 79% at 3 mo with more Australian patients achieving clinical response compared to Oxford (83% vs 70% P = 0.01). Clinical remission for all patients was 56%, 62% and 60% at 3, 6 and 12 mo respectively. Anti-TNF naive patients were more likely to achieve remission than exposed patients at all the time points (3 mo 66% vs 40% P < 0.001, 6 mo 73% vs 46% P < 0.001, 12 mo 66% vs 51% P = 0.03). More Australian patients achieved endoscopic remission at 6 mo compared to Oxford (69% vs 43% P = 0.01). On multi-variate analysis, anti-TNF naïve patients were 1.8 (95%CI: 1.3-2.3) times more likely to achieve remission than anti-TNF exposed (P < 0.001). 32 patients (11%) had colectomy by 12 mo.
CONCLUSION VDZ was safe and effective with 60% of UC patients achieving clinical remission at 12 mo and prior anti-TNF exposure influenced this outcome.

Abstract
BACKGROUND Virtual clinics represent a novel model of care in inflammatory bowel disease. Their effectiveness in promoting high quality use of biologic therapy and facilitating a treat-to-target approach is unknown. AIM To evaluate clinical and process-driven outcomes in a virtual clinic compared to standard outpatient care amongst patients receiving intensified anti-TNF therapy for secondary loss of response. METHODS We performed a retrospective multi-centre, parallel, observational cohort study of Crohn's disease patients receiving intensified anti-TNF therapy for secondary loss of response. Objective assessments of disease activity and anti-TNF trough levels at secondary loss of response and during subsequent 6-month semesters, were compared longitudinally between virtual clinic and standard outpatient care cohorts. The primary endpoint was treatment success, with appropriateness of dose intensification, tight disease monitoring and treatment de-escalation representing secondary outcomes. RESULTS Of 149 patients with similar baseline characteristics, 69 were managed via a virtual clinic and 80 via standard outpatient care. There were higher rates of treatment success in the virtual clinic cohort (60.9 vs 35.0%, P < 0.002). Rates of appropriate dose intensification (82.6% vs 40.0%, P < 0.001), biomarker remission (faecal calprotectin P = 0.002), tight-disease monitoring (84.1% vs 28.8%, P < 0.001) and treatment de-escalation (21.3% vs 10.0%, P = 0.027) also favoured the virtual clinic cohort. CONCLUSION This study favoured a virtual clinic-led model-of-care over standard outpatient care in facilitating treatment success as part of an effective treat-to-target approach in Crohn's disease. A virtual clinic model-of-care also improved treatment outcomes and quality of use of intensified anti-TNF therapy through processes that promoted appropriate dose intensification and tight-disease monitoring, while encouraging more frequent dose de-escalation.

Abstract
BACKGROUND AND AIM Chronic intestinal failure requiring home parenteral nutrition (HPN) is a disabling condition that is best facilitated by a multidisciplinary approach to care. Variation in care has been identified as a key barrier to achieving quality of care for patients on HPN and requires appropriate strategies to help standardize management. METHOD The Australasian Society for Parenteral and Enteral Nutrition (AuSPEN) assembled a multidisciplinary working group of 15 clinicians to develop a quality framework to assist with the standardization of HPN care in Australia. Obstacles to quality care specific to Australia were identified by consensus. Drafts of the framework documents were based on the available literature and refined by two Delphi rounds with the clinician work group, followed by a further two involving HPN consumers. The Oxford Centre for Evidence-Based Medicine Levels of Evidence was used to assess the strength of evidence underpinning each concept within the framework documents. RESULTS Quality indicators, standards of care, and position statements have been developed to progress the delivery of quality care to HPN patients. CONCLUSION The quality framework proposed by AuSPEN is intended to provide a practical structure for clinical and organizational aspects of HPN service delivery to reduce variation in care and improve quality of care and represents the initial step towards development of a national model of care for HPN patients in Australia. While developed for implementation in Australia, the evidence-based framework also has relevance to the international HPN community.

Abstract
Patients with malignancies require chemotherapy and other immunosuppressive therapies for treatment. Because of this immunosuppression, in patients who have ever been exposed to hepatitis B it is possible for reactivation to occur. This reactivation can be fatal. Reactivation is particularly likely in patients who receive B cell-active agents such as rituximab. The occurrence of reactivation flares may also delay further chemotherapy, which can negatively affect the outcome of the underlying malignancy. Accordingly, it is important to screen patients for markers of hepatitis B and institute antiviral prophylaxis to prevent reactivation.

Abstract
Organ transplantation is a lifesaving procedure for many patients. To prevent rejection or graft-versus-host disease, recipients require long-term immunosuppression. In patients who have ever been exposed to hepatitis B, it is possible for reactivation to occur; this includes patients who are anti-hepatitis B core antibody-positive only or both anti-hepatitis B core antibody-positive and hepatitis B surface antibody-positive. The susceptibility to this varies with the nature of the transplant. Hepatitis B can be transmitted from donor to recipient. It is important to assess the hepatitis B status and formulate a strategy to prevent transmission and prevent reactivation.
