Clinical Long-Term Outcomes of Patient-Reported Outcomes in the Prospective Real-World Tofacitinib Response in Ulcerative Colitis Registry. Clin Transl Gastroenterol 2024; 15:e00669. [PMID: 38131617 PMCID: PMC10962890 DOI: 10.14309/ctg.0000000000000669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Accepted: 12/14/2023] [Indexed: 12/23/2023] Open
Abstract
INTRODUCTION We previously reported the results of tofacitinib induction therapy in the prospective multisite US real-world Tofacitinib Response in Ulcerative Colitis registry. We now assessed patient-reported outcomes (PROs) and predictors of success during tofacitinib maintenance therapy. METHODS Tofacitinib Response in Ulcerative Colitis included 103 patients with refractory ulcerative colitis (UC); 67% had failed ≥ 2 biologics. Patients reported the Simple Clinical Colitis Activity Index (SCCAI), Patient-Reported Outcome Measurement Information System measures for anxiety, depression, social satisfaction, and adverse events between weeks 8 and 52 using a web-based system. Paired t test and P for trend were used to compare changes in PRO measures over time. Bivariate analyses and logistic regression models were used to determine factors associated with response (SCCAI <5) or remission (SCCAI <2) at week 52. RESULTS Of 103 patients, 82.5% entered the maintenance phase and 43.7% remained on tofacitinib at week 52. Tofacitinib de-escalation to 5 mg BID occurred in 15% of patients. At week 52, 42.7% and 31.1% of all patients reported an SCCAI <5 and SCCAI ≤2, respectively. Normalization of bowel frequency, rectal bleeding, and urgency occurred in 79%, 61%, and 48% of patients remaining on maintenance therapy. Social satisfaction improved significantly ( P < 0.001), while anxiety and depression scores only numerically improved. No consistent predictors for tofacitinib long-term treatment efficacy were identified, and safety findings were consistent with the known safety profile of tofacitinib. DISCUSSION Tofacitinib is an effective maintenance therapy in patients with refractory UC. Dose reductions infrequently occurred during maintenance. Unmet needs in UC maintenance include improvement of urgency and psychosocial factors (NCT03772145).

Efficacy and Safety of Approximately 3 Years of Continuous Ozanimod in Moderately to Severely Active Ulcerative Colitis: Interim Analysis of the True North Open-label Extension. J Crohns Colitis 2024; 18:264-274. [PMID: 37651686 PMCID: PMC10896634 DOI: 10.1093/ecco-jcc/jjad146] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Indexed: 09/02/2023]
Abstract
BACKGROUNDS AND AIMS This interim analysis from the True North open-label extension [OLE] study examines efficacy and safety of approximately 3 years of continuous ozanimod treatment in patients with moderately to severely active ulcerative colitis. METHODS Clinical responders after 52 weeks of ozanimod during the phase 3 True North study, who continued treatment in the OLE, were evaluated. Efficacy, including endoscopic and histological endpoints, was assessed during the OLE for approximately 2 additional years through OLE Week 94, using observed case [OC] and nonresponder imputation [NRI] analyses. Adverse events were monitored from True North baseline through OLE data cutoff and expressed as exposure-adjusted incidence rates. RESULTS This analysis included 131 patients; 54% had achieved corticosteroid-free remission at True North Week 52. In OC analyses, clinical response, clinical remission, and corticosteroid-free remission were achieved by 91.4%, 69.1%, and 67.9% of patients, respectively, at OLE Week 94 [146 weeks of total treatment]. Similarly, endoscopic improvement, histological remission, and mucosal healing were achieved by 73.3%, 67.3%, and 56.3% of patients, respectively, at OLE Week 94. Efficacy rates were lower using NRI analyses, but maintenance of efficacy was demonstrated through OLE Week 94. No new safety signals emerged from this analysis. Serious infections, malignancy, cardiovascular events, and hepatic events occurred infrequently. CONCLUSIONS Among patients who achieved clinical response after 1 year of ozanimod treatment during True North, a high percentage sustained clinical and mucosal efficacy over 2 additional years in the OLE. No new safety signals were observed with long-term ozanimod use.

Efficacy and safety of 48 weeks of guselkumab for patients with Crohn's disease: maintenance results from the phase 2, randomised, double-blind GALAXI-1 trial. Lancet Gastroenterol Hepatol 2024; 9:133-146. [PMID: 38104569 DOI: 10.1016/s2468-1253(23)00318-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 09/12/2023] [Accepted: 09/12/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND Many patients with moderately to severely active Crohn's disease do not respond to available therapies or lose response over time. The GALAXI-1 study previously found that three intravenous guselkumab dosages showed superior clinical and endoscopic outcomes over placebo at week 12 in patients with moderately to severely active Crohn's disease. We report the safety and efficacy of subcutaneous guselkumab maintenance regimens to week 48 in the GALAXI-1 study. METHODS We did a phase 2, randomised, multicentre, double-blind trial. Adult patients with moderately to severely active Crohn's disease were randomly allocated with a computer-generated randomisation schedule to receive one of five treatment groups, with regimens consisting of an intravenous induction phase transitioning to a subcutaneous maintenance phase starting at week 12 in a treat-through design: (1) guselkumab 200→100 mg group (200 mg intravenous at weeks 0, 4, and 8, then 100 mg subcutaneous every 8 weeks; (2) guselkumab 600→200 mg group (600 mg intravenous at weeks 0, 4, and 8, then 200 mg subcutaneous every 4 weeks); (3) guselkumab 1200→200 mg group (1200 mg intravenous at weeks 0, 4, and 8, then 200 mg subcutaneous every 4 weeks); (4) ustekinumab group (approximately 6 mg/kg intravenous at week 0, then 90 mg subcutaneous every 8 weeks); or (5) placebo group (placebo induction followed by either placebo maintenance [for those with CDAI clinical response at week 12] or crossover to ustekinumab [for those without CDAI clinical response at week 12]). Endpoints assessed at week 48 included CDAI remission (CDAI score <150), endoscopic response (≥50% improvement from baseline in SES-CD or SES-CD score ≤2), and endoscopic remission (SES-CD score ≤2) in the primary efficacy analysis population of all randomised patients who received at least one dose of study drug, excluding those discontinued during a temporary study pause. Safety analyses included all randomised patients who received at least one study drug dose. This trial is registered at Clinical Trials.gov (NCT03466411) and is active but not recruiting. FINDINGS Among 700 patients screened, 309 (112 biologic-naive; 197 biologic-experienced) were included in the primary efficacy analysis population: 61 in the guselkumab 200→100 mg group, 63 in the guselkumab 600→200 mg group, 61 in the guselkumab 1200→200 mg group, 63 in the ustekinumab group, and 61 in the placebo group. 126 (41%) women and 183 (59%) men were included, with median age 36·0 years (IQR 28·0-49·0). At week 48, the numbers of patients with CDAI clinical remission were 39 (64%) in the guselkumab 200→100 mg group, 46 (73%) in the guselkumab 600→200 mg group, 35 (57%) in the guselkumab 1200→200 mg group, and 37 (59%) in the ustekinumab group. The corresponding numbers of patients with endoscopic response were 27 (44%), 29 (46%), 27 (44%), and 19 (30%), respectively, and endoscopic remission was seen in 11 (18%), 11 (17%), 20 (33%), and four (6%) patients, respectively. In the placebo group, 15 patients were in CDAI clinical response at week 12 and continued placebo; of these, nine (60%) were in clinical remission at week 48. 44 patients in the placebo group were not in CDAI clinical response at week 12 and crossed over to ustekinumab; of these, 26 (59%) were in clinical remission at week 48. Up to week 48, adverse events frequencies in the safety population (n=360) were 46 (66%) of 70 patients (464·9 events per 100 patient-years of follow-up) in the placebo group, 163 (74%) of 220 patients (353·1 per 100 patient-years) in the three guselkumab groups combined, and 60 (85%) of 71 patients (350·7 per 100 patient-years) in the ustekinumab group. Among patients treated with guselkumab or ustekinumab, the most frequently reported infections up to week 48 were nasopharyngitis (25 [11%] of 220 guselkumab recipients, 12 [11%] of 114 ustekinumab recipients) and upper respiratory infections (13 [6%] guselkumab recipients, eight [7%] ustekinumab recipients). After week 12, one patient who responded to placebo induction and two guselkumab-treated patients had serious infections. No active tuberculosis, opportunistic infections, or deaths occurred. INTERPRETATION Patients receiving guselkumab intravenous induction and subcutaneous maintenance treatment achieved high rates of clinical and endoscopic efficacy up to week 48. No new safety concerns were identified. FUNDING Janssen Research & Development.

Unmet Needs in Real-World Advanced Therapy-Naïve and -Experienced Patients with Moderately to Severely Active Ulcerative Colitis in the United States. Adv Ther 2023; 40:4321-4338. [PMID: 37458875 PMCID: PMC10499754 DOI: 10.1007/s12325-023-02605-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Accepted: 06/28/2023] [Indexed: 09/14/2023]
Abstract
INTRODUCTION Despite availability of advanced therapies (ATs) for ulcerative colitis (UC), many patients fail to respond to treatment. This study examined real-world clinical and humanistic outcomes associated with current treatments in patients with UC. METHODS This cross-sectional study used US data from the Adelphi Real World Disease Specific Programme for inflammatory bowel disease from before (2017-2018) and during the COVID-19 pandemic (2020-2021). Physicians (gastroenterologists) seeing > 5 patients/month reported patients' disease characteristics, current symptoms and treatments, and reasons for treatment choices for their next seven consecutive patients aged ≥ 18 years with moderately to severely active UC before current treatment. Patients were asked to complete the EQ-5D-5L health-related quality of life (HRQoL) measure. ATs included tumor necrosis factor inhibitors (TNFis), integrin receptor antagonists, interleukin-12/23 antagonists, and Janus kinase inhibitors. Patients were classified as AT-naïve or AT-experienced based on current treatment received for ≥ 8 weeks and further classified as responders or non-responders based on symptoms, disease flare status, and remission. Descriptive analyses are presented. RESULTS The 2017-2018 cohort included 92 physicians and 539 patients (208 [38.6%] AT-experienced). The 2020-2021 cohort included 73 physicians and 448 patients (349 [77.9%] AT-experienced). TNFis were the most common ATs. In 2017-2018, 195 (58.9%) AT-naïve and 113 (54.3%) AT-experienced patients were non-responders; in 2020-2021 this was 57 (57.6%) and 182 (52.1%). Efficacy and induction of remission were physicians' most common reasons for AT choice. Dislike of injections/infusions was the most common reason for eligible patients not receiving biologic therapy. Numerically, non-responders (both AT-naïve and AT-experienced) had more symptoms, overall pain and fatigue, and lower HRQoL scores than responders. CONCLUSIONS Before (2017-2018) and during the pandemic (2020-2021), over half of patients with UC did not respond to AT. Non-responders carried a high burden of disease. Alternative therapies are urgently needed to treat UC.

Indications and safety of newer IBD treatments in the older patient. Curr Gastroenterol Rep 2023:10.1007/s11894-023-00874-9. [PMID: 37227615 DOI: 10.1007/s11894-023-00874-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/27/2023] [Indexed: 05/26/2023]
Abstract
PURPOSE OF REVIEW Treatment of inflammatory bowel disease (IBD) in the elderly requires special attention to treatment efficacy while considering drug safety, other medical comorbidities, and the patients' risk for treatment related adverse events. In this article, we reviewed the indications and safety of the newer IBD therapies in the older IBD patient beyond anti-TNF agents, thiopurines, and corticosteroids. RECENT FINDINGS Vedolizumab, ustekinumab, and risankizumab have favorable side effect profiles with regards to infections and malignancy. Ozanimod has a favorable side effect profile with regards to infection and malignancy, however cardiac events and macular edema are potential risks. Tofacitinib and upadacitinib are associated with an increased risk of serious infections, herpes zoster, malignancy, and have potential for an increased risk of cardiac events and thrombosis. From a safety profile perspective, vedolizumab, ustekinumab, and risankizumab should be considered first line treatment options for moderate-to-severe IBD in the elderly. Risk-benefit discussions are indicated for ozanimod, tofacitinib, and upadacitinib.

A Novel Remote Patient and Medication Monitoring Solution to Improve Adherence and Persistence With Inflammatory Bowel Disease Therapy (ASSIST Study): Protocol for a Randomized Controlled Trial. JMIR Res Protoc 2022; 11:e40382. [PMID: 36520519 PMCID: PMC9801266 DOI: 10.2196/40382] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 10/26/2022] [Accepted: 10/28/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Inflammatory bowel diseases (IBDs) are chronic inflammatory conditions of the gastrointestinal tract. Although adherence to IBD therapies is associated with improved clinical outcomes, overall adherence is poor. Consequently, there is a critical need to develop interventions that monitor adherence in real time and identify reasons for nonadherence to support clinical teams in initiating effective interventions. Recently, electronic- and web-based platforms have been developed to monitor adherence and guide interventions. A novel remote therapy monitoring (RTM) technology, the Tappt digital health system, has been developed to monitor real-time medication adherence patterns through smart label technologies, capture patient-reported outcomes and barriers to care, and process patient data through algorithms that trigger personalized digital and human touch points between clinical visits. Such a digital health solution enables care teams to proactively identify and mitigate nonadherence and worsening clinical outcomes. OBJECTIVE We propose a 12-month multicenter randomized controlled trial to assess the effectiveness of the Tappt digital health system on adherence, clinical outcomes, and health care use among patients diagnosed with IBD starting a new oral or subcutaneous therapy. METHODS The digital health system intervention will provide automatic measurement of medication adherence via smart labels for pill bottles or injectors as well as a monitoring platform for providers. The system will prompt patients to complete a two-item assessment of symptoms monthly using the PRO-2 scales for UC and Crohn disease, from which increased symptoms will be alerted to providers. Participants will be randomized 2:1 to the intervention group or the control group, which will receive standard of care. All participants are required to complete questionnaires at baseline as well as at 12, 26, and 52 weeks. Assuming an adherence rate of 0.65 and 0.9 among control and intervention participants, respectively, we will need to enroll 123 participants: 82 (66.7%) in the intervention group and 41 (33.3%) controls. We will compare adherence as measured by the medication possession ratio, defined as the number of days of supply of medication obtained during the observation period out of the total number of days in the observation period, in participants using the RTM versus those receiving standard of care. We will also compare clinical outcomes and health care use in participants using the RTM versus those receiving standard of care. RESULTS We anticipate starting recruitment in December 2022. CONCLUSIONS Effective medication adherence monitoring and intervention programs need to be cost-efficient, pose little or no burden to the patient, record reliable data in real time, and provide actionable insights to the health care team. We anticipate the Tappt digital health system to improve the medication possession ratio, clinical outcomes, and health care use compared with standard of care.

Recommendations on the Appropriate Management of Steroids and Discharge Planning During and After Hospital Admission for Moderate-Severe Ulcerative Colitis: Results of a RAND Appropriateness Panel. Am J Gastroenterol 2022; 117:1288-1295. [PMID: 35416799 PMCID: PMC9437635 DOI: 10.14309/ajg.0000000000001775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 04/04/2022] [Indexed: 12/11/2022]
Abstract
INTRODUCTION Limited guidance exists for the postdischarge care of patients with ulcerative colitis hospitalized for moderate-severe flares. METHODS RAND methodology was used to establish appropriateness of inpatient and postdischarge steroid dosing, discharge criteria, follow-up, and postdischarge biologic or small molecule initiation. A literature review informed on the panel's voting, which occurred anonymously during 2 rounds before and after a moderated virtual session. RESULTS Methylprednisolone 40-60 mg intravenous every 24 hours or hydrocortisone 100 mg intravenous 3 times daily is appropriate for inpatient management, with methylprednisolone 40 mg being appropriate if intolerant of higher doses. It is appropriate to discharge patients once rectal bleeding has resolved (Mayo subscore 0-1) and/or stool frequency has returned to baseline frequency and form (Mayo subscore 0-1). It is appropriate to discharge patients on 40 mg of prednisone after observing patients for 24 hours in hospital to ensure stability before discharge. For patients being discharged on steroids without in-hospital biologic or small molecule therapy initiation, it is appropriate to start antitumor necrosis factor (TNF) therapy after discharge for anti-TNF-naive patients. For anti-TNF-exposed patients, it is appropriate to start vedolizumab or ustekinumab for all patients and tofacitinib for those with a low risk of adverse events. It is appropriate to follow up patients clinically within 2 weeks and with lower endoscopy within 4-6 months after discharge. DISCUSSION We provide recommendations on the inpatient and postdischarge management of patients with ulcerative colitis hospitalized for moderate-severe flares.

Abstract
BACKGROUND Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). Using a novel electronic reporting tool, we aimed to prospectively describe the onset of tofacitinib efficacy during induction therapy in a real-world study. METHODS Patient-reported outcome data (PROs) including the simple clinical colitis activity index (SCCAI), PRO Measurement Identification Systems (PROMIS) measures, and adverse events were collected daily for the first 14 days and at day 28 and 56. Paired t tests and P for trend were utilized to compare changes in SCCAI over time. Bivariate analyses and logistic regression models were performed to describe response (SCCAI <5) and remission (SCCAI ≤2) by clinical factors. RESULTS Of all included patients (n = 96), 67% had failed ≥2 biologics, and 61.5% were on concomitant steroids. Starting at day 3, PROs showed significant and persistent decline of the mean SCCAI (-1.1, P < 000.1) including significantly lower SCCAI subscores for stool frequency (-0.3; P < .003), bleeding (-0.3; P < .0002) and urgency (-0.2; P < .001). Steroid-free remission at day 14, 28, and 56 was achieved in 25%, 30.2%, and 29.2% of patients, respectively. Neither prior biologics nor endoscopic severity were independently predictive of response or remission in multivariate models. Numeric improvements in all PROMIS measures (anxiety, depression, social satisfaction) were seen through day 56. Rates of discontinuation due to adverse events were low. CONCLUSIONS In this prospective real-world study, tofacitinib resulted in a rapid and persistent improvement in UC disease activity PROs. The safety findings were consistent with the established safety profile of tofacitinib.

Abstract
BACKGROUND & AIMS Guselkumab, a selective p19 interleukin-23 antagonist, is approved for the treatment of plaque psoriasis and psoriatic arthritis. This study evaluated the efficacy and safety of guselkumab in patients with moderately to severely active Crohn's disease with inadequate response or intolerance to conventional or biologic therapy. METHODS GALAXI-1, a phase 2, double-blind, placebo-controlled study, randomized patients 1:1:1:1:1 to intravenous guselkumab 200 mg, 600 mg, or 1200 mg at weeks 0, 4, and 8; intravenous ustekinumab approximately 6 mg/kg at week 0 and 90 mg subcutaneously at week 8; or placebo. Change from baseline in Crohn's Disease Activity Index score (primary end point), clinical remission, clinical response, Patient Reported Outcomes-2 remission, clinical-biomarker response, endoscopic response (major secondary end points), and safety in guselkumab-treated patients vs placebo were evaluated through week 12. Ustekinumab was a reference arm. RESULTS Of 309 patients evaluated, approximately 50% had disease refractory to prior biologic therapy. At week 12, significantly greater reductions in Crohn's Disease Activity Index from baseline (least squares means: 200 mg: -160.4, 600 mg: -138.9, and 1200 mg: -144.9 vs placebo: -36.2; all, P < .05) and significantly greater proportions of patients achieved clinical remission in each guselkumab group vs placebo (Crohn's Disease Activity Index <150; 57.4%, 55.6%, and 45.9% vs 16.4%; all, P < .05). Greater proportions of patients receiving guselkumab achieved clinical response, Patient Reported Outcomes-2 remission, clinical-biomarker response, and endoscopic response at week 12 vs placebo. Efficacy of ustekinumab vs placebo was also demonstrated. Safety event rates were generally similar across treatment groups. CONCLUSIONS At week 12, all 3 dose regimens of guselkumab induced greater clinical and endoscopic improvements vs placebo, with a favorable safety profile. CLINICALTRIALS gov, Number: NCT03466411.

Impact of Cannabis Use on Inpatient Inflammatory Bowel Disease Outcomes in 2 States Legalizing Recreational Cannabis. CROHN'S & COLITIS 360 2022; 4:otac015. [PMID: 36777043 PMCID: PMC9802039 DOI: 10.1093/crocol/otac015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Indexed: 11/14/2022] Open
Abstract
Background We evaluated the impact of recreational cannabis legalization on use and inpatient outcomes of patients with inflammatory bowel disease (IBD). Methods Hospitalized adult patients in Colorado and Washington before (2011) and after (2015) recreational cannabis legalization were compared by chi-square tests for categorical variables and t-tests for continuous variables. Multivariable regression models adjusting for demographic data were fit to assess the association of cannabis use with hospital outcomes. Results Reported cannabis use increased after legalization (1.2% vs 4.2%, P < .001). On multivariable analysis, in 2011, cannabis users were less likely to need total parenteral nutrition (odds ratio 0.12, P = .038), and in 2015 had less hospital charges ($-8418, P = .024). Conclusions The impact of cannabis legalization and use on IBD is difficult to analyze but may have implications on inpatient IBD outcomes as described in this retrospective analysis. Large, prospective studies are needed to evaluate other IBD outcomes based on cannabis legalization and use.

Abstract
BACKGROUND With the management of inflammatory bowel disease (IBD) becoming increasingly complex, incorporating preventive care health maintenance measures can be challenging. The aim of developing these updated recommendations is to provide more specific details to facilitate their use into a busy clinical practice setting. METHOD Fifteen statements were formulated with recommendations regarding the target, timing, and frequency of the health maintenance interventions in patients with IBD. We used a modified Delphi method and a literature review to establish a consensus among the panel of experts. The appropriateness of each health maintenance statement was rated on a scale of 1 to 5 (1-2 as inappropriate, and 4-5 as appropriate) by each panelist. Interventions were considered appropriate, and statements were accepted if ≥80% of the panelists agreed with a score ≥4. RESULTS The panel approved 15 health maintenance recommendations for adults with IBD based on the current literature and expert opinion. These recommendations include explicit details regarding specific screening tools, timing of screening, and vaccinations for adults with IBD. CONCLUSIONS Patients with IBD are at an increased risk for infections, malignancies, and other comorbidities. Given the complexity of caring for patients with IBD, this focused list of recommendations can be easily incorporated in to clinical care to help eliminate the gap in preventative care for patients with IBD.

Abstract
Background and Aims Therapeutic drug monitoring (TDM) with measurement of serum drug and antidrug antibody concentrations is used to optimize tumor necrosis factor antagonists (anti-TNF). The endoscopic healing index (EHI) is a validated serum-based assay to measure mucosal inflammation in adults with Crohn disease (CD). Our objectives were to evaluate the relationship between EHI and TDM results and to determine the anti-TNF concentration range associated with EHI <20 (consistent with endoscopic remission). Methods Adult and pediatric patients with CD (N = 1731) were selected retrospectively from a clinical laboratory cohort. Patients were selected if they had an ICD-10 code for CD and if results for EHI and TDM were available within 30 days of each other. The relationship between EHI and TDM results was examined and the anti-TNF concentration range associated with EHI <20 vs >50 was evaluated. Results Median anti-TNF concentration was higher in patients with EHI <20 vs >50 for infliximab (N = 796): 11.1 vs 3.4 µg/mL and for adalimumab (N = 935): 9.2 vs 5.0 µg/mL (P < 0.0001 both drugs). Patients with antibodies to infliximab (12.8%) or adalimumab (14.9%) had lower anti-TNF concentrations (P < 0.001 both drugs) and higher EHI (P < 0.01 both drugs). The concentration range for infliximab: 5-15 µg/mL (5-9 µg/mL in pediatric patients) and for adalimumab: 5-10 µg/mL (8 µg/mL in pediatric patients) best discriminated EHI <20 vs >50. Conclusions We report the anti-TNF concentration range associated with EHI <20. Combined testing of EHI and TDM is proposed as a noninvasive approach for treat-to-target management which could improve the ability to monitor disease and optimize anti-TNF therapy.

Abstract
PURPOSE Infliximab promotes remission in patients with inflammatory bowel disease (IBD) and rheumatologic disease (RD). Rapid infliximab infusions (RI) reduce infusion time from 2 hours to 1 hour and can enhance access to care, as defined by capacity, safety, and patient characteristics. Our hypothesis for the study described here was that use of RI can enhance access for patients. METHODS Data on all patients receiving infliximab for IBD or RD at our outpatient infusion center from February 2016 to August 2017 were retrospectively analyzed. Demographic and clinical information were collected. RESULTS Of 348 patients who received infliximab, 205 had IBD and 143 had RD. In terms of capacity, 40% of patients received RI, resulting in a 16.1% decrease in average daily infusion time and a 9.8% increase in average daily available scheduled infusion chair time (P = 0.720). In terms of safety, 4 patients switched back to standard infusions after RI, after 3 specifically had reactions to RI. In terms of patient characteristics, more patients with RD versus IBD received RI (P = 0.020). Among the patients with RD, a lower proportion receiving RI were female (P = 0.043). For the patients with IBD, a higher proportion receiving RI were white (P = 0.048). Among both patients with RD and patients with IBD, a higher proportion receiving RI had private insurance (P = 0.016 and P = 0.018, respectively). CONCLUSION RI were safe and increased available chair time. Females with RD, patients of non-White race with IBD, and patients with public insurance were less likely to receive RI. Future directions include patient surveys and evaluation of implicit bias against patient factors that may impact access to RI.

The Automatic Substitution of Biosimilars: Definitions of Interchangeability are not Interchangeable. Adv Ther 2021; 38:2077-2093.

Abstract
In the USA, an interchangeability designation provides biosimilar sponsors with a pathway for achieving what is standard for small-molecule generics: pharmacy-level auto-substitution for an innovator. No other major health authority links interchangeability to automatic substitution, as all require the involvement of the prescriber or patient in a medication change. This editorial considers the clinical impact and practicality of auto-substitution. First, interchangeability is linked to non-medical switching (NMS), the practice of switching treatment in patients with stable disease for non-clinical reasons. NMS may generate negative sentiment in those unwilling or reluctant to switch, which can adversely impact treatment outcomes (i.e., nocebo effect). Indeed, in real-world studies of tumor necrosis factor inhibitors, discontinuation rates have been shown to be higher in patients switched to biosimilars for non-medical reasons than in historical cohorts maintained on innovators. Second, interchangeability may impede pharmacovigilance and traceability, as not all jurisdictions require innovators and biosimilars to have distinct biologic names. Third, an interchangeability designation from the US Food and Drug Administration only permits a biosimilar to be automatically substituted for its innovator, not other biosimilars (if available). Pharmacist education would be needed to avoid off-label, automatic substitution among biosimilars of a single innovator. Last, once granted, an interchangeability designation exists in perpetuity under current US federal law. However, the supply chains of innovators and biosimilars are maintained independently, with no requirement for reconfirmation of biosimilarity or interchangeability. We feel that additional guidance is needed for the auto-substitution of biosimilars and innovators to become a reality.

Abstract
BACKGROUND Inflammatory bowel diseases (IBD), including Crohn disease (CD) and ulcerative colitis (UC), are complex disorders with multiple comorbidities. We conducted international patient and physician surveys to evaluate current experiences and perceptions of patients with CD or UC and physicians who treat IBD. METHODS The IBD Global Assessment of Patient and Physician Unmet Need Surveys comprised a patient survey and a physician survey, fielded in North America and Europe between August 16, 2019, and November 10, 2019. Adults with CD or UC (targeted 1:1 ratio) were recruited from physicians, patient advocacy groups, and recruitment panels; physicians were recruited by recruitment agencies and panels. RESULTS In total, 2398 patients with IBD (1368 CD, 1030 UC) and 654 physicians completed surveys. Anxiety and depression were the most common comorbidities among patients with IBD. Patients and physicians were generally aligned on treatment goals and patient-physician communication. Patients with IBD reported high quality-of-life impact by rectal urgency and need to use the toilet, which were rated as lower-impact by physicians. Patients defined remission based on symptoms; physicians defined remission based primarily on clinical tests. Patients expected current treatments to control their disease for a longer duration than did physicians. Patients expressed more concern about corticosteroid use compared with physicians; many physicians reported prescribing corticosteroids for more than 4 months per year in some patients. CONCLUSIONS Patients could benefit from education about disease remission and expectations for current therapies. High corticosteroid use is concerning to patients, and physicians should minimize the use of corticosteroids for extended periods of time.

Economic Outcomes of Inflammatory Bowel Disease Patients Switching to a Second Anti-Tumor Necrosis Factor or Vedolizumab. CROHN'S & COLITIS 360 2020; 2:otaa031.

Abstract
Background Anti-tumor necrosis factor (TNF) therapies have been the mainstay of inflammatory bowel disease (IBD) treatment for nearly 2 decades. Therapies with novel mechanisms of action have been recently developed. This study compared healthcare resource utilization (HRU) and costs incurred while switching from an initial anti-TNF to another anti-TNF versus switching to vedolizumab. Methods Adults with IBD who switched from initial anti-TNF to another anti-TNF or vedolizumab were identified from Truven MarketScan claims database (January 1, 2000-September 30, 2017). Patient characteristics were assessed during the 6-month period before the initiation date of the switched-to treatment (index date). Adjusted analyses of all-cause and disease-related HRU and costs during the 6-month period after the index date (study period) were performed. Anti-TNF and vedolizumab switchers with Crohn's disease (CD) and ulcerative colitis (UC) were separately compared. Results A total of 502 vedolizumab, 1708 adalimumab, 755 infliximab, and 703 other switchers with CD and 461, 428, 311, and 148 with UC, respectively, were identified. Patient demographics were similar across cohorts. Total all-cause costs were significantly higher for vedolizumab than adalimumab, infliximab, and certolizumab switchers in the CD cohort and adalimumab and infliximab in the UC cohort. In both cohorts, adalimumab and other switchers had fewer all-cause and IBD-related outpatient visits than vedolizumab switchers. Conclusions CD/UC patients who switched to vedolizumab from initial anti-TNF had higher total and treatment costs than patients who switched to another anti-TNF, except for UC patients who switched to golimumab. Prospective studies should be conducted to confirm these findings.

Abstract
BACKGROUND Surgery is common in patients with Crohn's disease and can contribute significantly to patient morbidity. The National Surgical Quality Improvement Program surgical risk calculator (NSQIP-SRC) that is currently utilized to predict surgical risk does not take Crohn's disease into account and, as a result, seems to underestimate risk in this patient population. This study aimed to evaluate the accuracy of the NSQIP-SRC in Crohn's disease patients and to evaluate the utility of disease severity scores in predicting surgical risk. METHODS Between 2011 and 2017, there were 176 surgical cases involving Crohn's disease patients. Demographic data and 30-day surgical outcomes were collected. Disease severity scores including Harvey Bradshaw Index (HBI), Crohn's Disease Activity Index (CDAI), Simple Endoscopic Score for Crohn's Disease (SES-CD), and NSQIP-SRC risk percentages were calculated. RESULTS Patients in remission based on HBI had a complication rate of 8.57% (n = 3), while those with mild or moderate-severe disease had rates of 33.33% (n = 11) and 38.46% (n = 20) respectively (p = 0.0045). In multivariable analysis, those with mild (OR; 8.37, 95% CI; 1.64, 42.78; p = 0.011) or moderate-severe (OR; 11.69, 95% CI; 2.42, 56.46; p = 0.002) disease had increased odds of complication compared to remission. Complication rate was not associated with NSQIP-SRC percent risk of any complication. CONCLUSION NSQIP-SRC does not accurately predict risk in patients with CD undergoing surgery. Higher disease activity based on HBI is associated with increased odds of complication and may prove to be more predictive of surgical complication in the Crohn's patient population.

Abstract
PURPOSE OF REVIEW This review addresses our current knowledge of immune-mediated colitis (IMC) and offers a practical guide to its management. RECENT FINDINGS Due to the similarity in clinical, endoscopic, and histologic findings between IMC and inflammatory bowel disease (IBD), gastroenterologists have tailored their approach to IMC management to that of IBD. Immune checkpoint inhibitors (ICIs) are monoclonal antibodies that augment the T-cell anti-tumor response of the immune system and have demonstrated their importance in the treatment of a wide range of malignancies. With the growing benefits of ICIs, there are immune-related adverse events (irAEs) that mirror many known autoimmune diseases. Diarrhea and IMC are the most common and severe irAEs noted. No standardized guidelines exist in the management of these irAEs.

Abstract
BACKGROUND We aimed to examine opioid use among adult patients with inflammatory bowel disease (IBD) in the United States and the impact of extended opioid use on emergency health care services and health care costs among patients. METHODS We conducted a retrospective cohort study using medical claims data from the Truven Health MarketScan research databases, consisting of patients across the United States with employer-based health insurance. Subjects with IBD were identified in 2009. The occurrence of an emergent encounter in 2010 and health care costs were assessed. RESULTS There were 76,171 subjects with 35,993 emergent encounters among the study population, for an overall rate of 0.47 per patient-year. However, these encounters were confined to 6.9% of patients overall. The median total charges per patient in 2010 were $5372. Extended opioid use in 2009 was associated with a higher odds of an emergent encounter in 2010 (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.67-1.98), higher incidence rate of emergent encounters (incidence rate ratio, 2.07; 95% CI, 1.91-2.24), and higher odds of being in the top quartile of cost in 2010 (OR, 1.90; 95% CI, 1.79-2.02). Depression was a strong predictor of extended opioid use (OR, 2.64; 95% CI, 2.49-2.81; P < 0.001). CONCLUSIONS Extended opioid use among patients with IBD is an important predictor of emergent encounters and is associated with higher total health care costs. Psychosocial comorbidities are significant predictors of extended opioid use in patients with IBD.

Abstract
Colorectal cancer (CRC) remains the third most common cause of cancer-related death in the United States and the fourth globally with a rising incidence. Inflammatory bowel disease (IBD) is a chronic immunologically mediated disease that imposes a significant associated health burden, including the increased risk for colonic dysplasia and CRC. Carcinogenesis has been attributed to chronic inflammation and associated with oxidative stress, genomic instability, and immune effectors as well as the cytokine dysregulation and activation of the nuclear factor kappa B (NFκB) signaling pathway. Current anti-inflammation therapies used for IBD treatment have shown limited effects on CRC chemoprevention, and their long-term toxicity has limited their clinical application. However, natural food-based prevention approaches may offer significant cancer prevention effects with very low toxicity profiles. In particular, in preclinical and clinical pilot studies, strawberry and black raspberry have been widely selected as food-based interventions because of their potent preventive activities. In this review, we summarize the roles of strawberry, black raspberry, and their polyphenol components on CRC chemoprevention in IBD.

Abstract
BACKGROUND Readmissions are common after hospitalization related to ulcerative colitis (UC). A risk score to stratify the severity of UC hospitalizations and risk of colectomy has been previously reported. Our aim was to predict hospital-related outcomes after hospitalizations for UC utilizing this severity score. METHODS We utilized the Nationwide Readmissions Database (2010-2014) for hospitalized patients with UC and differentiated patients by index severity (low, intermediate, high). Baseline characteristics, surgical rates, readmissions, mortality, and hospital outcomes were collected. The primary outcomes of interest included readmission and mortality rates. RESULTS There were 133,819 patients admitted with UC with 22,762 (17%) readmitted within 30 days. Those readmitted within 30 days had a 4.5% calendar year mortality rate, compared with 0.45% in those not readmitted within 30 days (P < 0.001). Index surgery rates (19.2% vs 12.3%), length of stay (6.9 vs 5.4 days), and hospital costs ($13,530 vs $10,366; P < 0.001 for all) were higher in those readmitted within 30 days. Patients with high-severity presentations had higher surgical rates (31.6%), higher 30-day and calendar year readmission rates (24.3% and 46.0%, respectively), increased index and calendar year mortality (2.5% and 2.0%, respectively), longer length of stay (15.1 days), and increased costs ($31,136) compared with those with low severity (P < 0.001 for all). Calendar-year survival rates in those with intermediate and high scores were significantly lower than in those with low scores. CONCLUSIONS An index severity score of intermediate or high and early readmissions are predictors of calendar year mortality. Future efforts should emphasize more focused care in high-risk patients, as this may reduce readmissions and improve outcomes.

Abstract
Objective Anti–tumor necrosis factor (anti‐TNF) medications are effective in controlling chronic inflammatory diseases, but information about their use and safety in pregnancy is limited. Consequently, anti‐TNF agents are often discontinued early in gestation. Certolizumab pegol (CZP), a PEGylated, Fc‐free anti‐TNF agent approved for the treatment of rheumatic diseases and/or Crohn's disease, has minimal to no active placental transfer. This analysis was undertaken to evaluate pregnancy outcomes in women receiving CZP, especially those exposed during early pregnancy. Methods Prospective and retrospective data on maternal CZP exposure were extracted from the UCB Pharma safety database through March 6, 2017. Analysis was limited to prospective reports to avoid potential bias associated with retrospective submissions. The numbers of live births, miscarriages, elective abortions, stillbirths, and major congenital malformations were ascertained. Results Of 1,137 prospectively reported pregnancies with maternal exposure to CZP, 528 (including 10 twin pregnancies) had 538 known outcomes: 459 live births (85.3%), 47 miscarriages (8.7%), 27 elective abortions (5.0%), and 5 stillbirths (0.9%). There were 8 major congenital malformations (1.7%) among the 459 infants. First trimester exposure occurred in 367 (81.2%) of 452 pregnancies resulting in 459 live births. Exposure during all 3 trimesters occurred in 201 (44.5%) of 452 pregnancies. Conclusion This analysis represents the largest cohort of pregnant women exposed to an anti‐TNF agent for management of chronic inflammatory diseases. Analysis of pregnancy outcomes does not indicate a teratogenic effect of CZP, compared to the general population, nor an increased risk of fetal death. The data are reassuring for women of childbearing age considering treatment with CZP.

Abstract
Electronic medical records (EMRs) have gained widespread use in clinical practice and by default serve as a large patient database with potential for use in clinical research. Although there remains significant interest in leveraging EMRs for research purposes, extraction of data has proven to be complex and with insufficient accuracy. We describe the limitations of an EMR in our attempt to conduct a seemingly simple study aimed at validating variables identified in the PRECiSE 3, a 7-year open label safety and efficacy study of certolizumab pegol in Crohn's disease that identified clinical factors that predicted both short- and long-term efficacy. A multicenter, retrospective cohort study from 8 academic and large community practices was performed, and data were collected from each respective EMR. Significant challenges with reliable capture of key data elements were encountered, and overall a screen fail rate of 91.8% across all sites was seen. We describe these challenges and potential future directions to work together to advance accuracy and implementation of the use of EMRs in inflammatory bowel disease.

Abstract
Inflammatory bowel disease (IBD) is a heterogeneous group of chronic diseases with a rising prevalence in the pediatric population, and up to 25% of IBD patients are diagnosed before 18 years of age. Adolescents with IBD tend to have more severe and extensive disease and eventually require graduation from pediatric care toadult services. The transition of patients from pediatric to adult gastroenterologists requires careful preparation and coordination, with involvement of all key players to ensure proper collaboration of care and avoid interruption in care. This can be challenging and associated with gaps in delivery of care. The pediatric and adult health paradigms have inherent differences between health care models, as well as health care priorities in IBD. The readiness of the young adult also influences this transition of care, with often times other overlaps in life events, such as school, financial independence and moving away from home. These patients are therefore at higher risk for poorer clinical disease outcomes. The aim of this paper is to review concepts pertinent to transition of care of young adults with IBD to adult care, and provides resources appropriate for an IBD pediatric to adult transition of care model.

Abstract
AIMS Inflammatory bowel disease (IBD) (e.g. ulcerative colitis [UC] and Crohn's disease [CD]) severely impacts patient quality-of-life. Moderate-to-severe disease is often treated with biologics requiring infusion therapy, adding incremental costs beyond drug costs. This study evaluates US hospital-based infusion services costs for treatment of UC or CD patients receiving infliximab or vedolizumab therapy. MATERIALS AND METHODS A model was developed, estimating annual costs of providing monitored infusions using an activity-based costing framework approach. Multiple sources (published literature, treatment product inserts) informed base-case model input estimates. RESULTS The total modeled per patient infusion therapy costs in Year 1 with infliximab and vedolizumab was $38,782 and $41,320, respectively, and Year 2+, $49,897 and $36,197, respectively. Drug acquisition cost was the largest total costs driver (90-93%), followed by costs associated with hospital-based infusion provision: labor (53-56%, non-drug costs), allocated overhead (23%, non-drug costs), non-labor (23%, non-drug costs), and laboratory (7-10%, non-drug costs). LIMITATIONS Limitations included reliance on published estimates, base-case cost estimates infusion drug, and supplies, not accounting for volume pricing, assumption of a small hospital infusion center, and that, given the model adopts the hospital perspective, costs to the patient were not included in infusion administration cost base-case estimates. CONCLUSIONS This model is an early step towards a framework to fully analyze infusion therapies' associated costs. Given the lack of published data, it would be beneficial for hospital administrators to assess total costs and trade-offs with alternative means of providing biologic therapies. This analysis highlights the value to hospital administrators of assessing cost associated with infusion patient mix to make more informed resource allocation decisions. As the landscape for reimbursement changes, tools for evaluating the costs of infusion therapy may help hospital administrators make informed choices and weigh trade-offs associated with providing infusion services for IBD patients.

Abstract
Ulcerative colitis can cause debilitating symptoms and complications such as colonic strictures, colonic dysplasia, colorectal cancer, and toxic megacolon or perforation. Goals of treatment in ulcerative colitis include resolution of gastrointestinal symptoms, healing of colonic mucosa, and prevention of disease complications. Our treatment armamentarium has expanded dramatically over the past 10 years, and we now have multiple biologic agents approved for the treatment of moderate-severe disease, in addition to conventional therapies such as 5-aminosalicylates, thiopurines, and corticosteroids. In this review, we will provide a detailed discussion of the three tumor necrosis factor-alpha (TNF-α) inhibitors currently approved for treatment of ulcerative colitis: infliximab, adalimumab, and golimumab. All three agents are effective for inducing and maintaining clinical response and remission in patients with ulcerative colitis, and they have comparable safety profiles. There are no head-to-head trials comparing their efficacy, and the choice of agent is most often based on insurance coverage, route of administration, and patient preference. Combination therapy with an immunomodulator is proven to be more effective than anti-TNF monotherapy, and patients who lose response to an anti-TNF agent should undergo dose intensification in order to regain clinical response. Despite therapeutic optimization, a significant percentage of patients will not achieve clinical remission with anti-TNF agents, and so newer therapies are on the horizon.

Abstract
OBJECTIVES Patients who are immunocompromised (IC) are at increased risk of Clostridium difficile infection (CDI), which has increased to epidemic proportions over the past decade. Fecal microbiota transplantation (FMT) appears effective for the treatment of CDI, although there is concern that IC patients may be at increased risk of having adverse events (AEs) related to FMT. This study describes the multicenter experience of FMT in IC patients. METHODS A multicenter retrospective series was performed on the use of FMT in IC patients with CDI that was recurrent, refractory, or severe. We aimed to describe rates of CDI cure after FMT as well as AEs experienced by IC patients after FMT. A 32-item questionnaire soliciting demographic and pre- and post-FMT data was completed for 99 patients at 16 centers, of whom 80 were eligible for inclusion. Outcomes included (i) rates of CDI cure after FMT, (ii) serious adverse events (SAEs) such as death or hospitalization within 12 weeks of FMT, (iii) infection within 12 weeks of FMT, and (iv) AEs (related and unrelated) to FMT. RESULTS Cases included adult (75) and pediatric (5) patients treated with FMT for recurrent (55%), refractory (11%), and severe and/or overlap of recurrent/refractory and severe CDI (34%). In all, 79% were outpatients at the time of FMT. The mean follow-up period between FMT and data collection was 11 months (range 3-46 months). Reasons for IC included: HIV/AIDS (3), solid organ transplant (19), oncologic condition (7), immunosuppressive therapy for inflammatory bowel disease (IBD; 36), and other medical conditions/medications (15). The CDI cure rate after a single FMT was 78%, with 62 patients suffering no recurrence at least 12 weeks post FMT. Twelve patients underwent repeat FMT, of whom eight had no further CDI. Thus, the overall cure rate was 89%. Twelve (15%) had any SAE within 12 weeks post FMT, of which 10 were hospitalizations. Two deaths occurred within 12 weeks of FMT, one of which was the result of aspiration during sedation for FMT administered via colonoscopy; the other was unrelated to FMT. None suffered infections definitely related to FMT, but two patients developed unrelated infections and five had self-limited diarrheal illness in which no causal organism was identified. One patient had a superficial mucosal tear caused by the colonoscopy performed for the FMT, and three patients reported mild, self-limited abdominal discomfort post FMT. Five (14% of IBD patients) experienced disease flare post FMT. Three ulcerative colitis (UC) patients underwent colectomy related to course of UC >100 days after FMT. CONCLUSIONS This series demonstrates the effective use of FMT for CDI in IC patients with few SAEs or related AEs. Importantly, there were no related infectious complications in these high-risk patients.

The association of psoriasiform rash with anti-tumor necrosis factor (anti-TNF) therapy in inflammatory bowel disease: a single academic center case series. J Crohns Colitis 2014; 8:480-8. [PMID: 24268978 DOI: 10.1016/j.crohns.2013.10.013] [Citation(s) in RCA: 47] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2013] [Revised: 10/14/2013] [Accepted: 10/29/2013] [Indexed: 02/08/2023]
Abstract
BACKGROUND & AIMS Anti-tumor necrosis factors (anti-TNF) including infliximab, adalimumab and certolizumab pegol are used to treat Crohn's disease (CD) and ulcerative colitis (UC). Paradoxically, while also indicated for the treatment of psoriasis, anti-TNF therapy has been associated with development of psoriasiform lesions in IBD patients and can compel discontinuation of therapy. We aim to investigate IBD patient, clinical characteristics, and frequency for the development of and outcomes associated with anti-TNF induced psoriasiform rash. METHODS We identify IBD patients on anti-TNFs with an onset of a psoriasiform rash. Patient characteristics, duration of anti-TNF, concomitant immunosuppressants, lesion distribution, and outcomes of rash are described. RESULTS Of 1004 IBD patients with exposure to anti-TNF therapy, 27 patients (2.7%) developed psoriasiform lesions. Psoriasiform rash cases stratified by biologic use were 1.3% for infliximab, 4.1% for adalimumab, and 6.4% for certolizumab. Average time on treatment (206.3weeks) and time on treatment until onset of psoriasiform lesions (126.9weeks) was significantly higher in the infliximab group. The adalimumab group had the highest need for treatment discontinuation (60%). The majority (59.3%) of patients were able to maintain on anti-TNFs despite rash onset. Among patients that required discontinuation (40.7%), the majority experienced improvement with a subsequent anti-TNF (66.7%). CONCLUSION 27 cases of anti-TNF associated psoriasiform lesions are reported. Discontinuation of anti-TNF treatment is unnecessary in the majority. Dermatologic improvement was achieved in the majority with a subsequent anti-TNF, suggesting anti-TNF induced psoriasiform rash is not necessarily a class effect.

Abstract
Diagnosis of inflammatory bowel disease (IBD) is complicated and is based on a combination of patient history and physical examination in association with laboratory, endoscopic, histologic, and radiographic investigations. Determination of the correct diagnosis is important for its implications in selecting treatment and in the timing and type of surgery that may be required. Information from testing incorporating serologic, genetic, and inflammatory markers can help to clarify the clinical picture. Measurement of biomarkers not only helps to differentiate a diagnosis of IBD versus non-IBD, it can also help to distinguish between ulcerative colitis and Crohn's disease in difficult cases. In this monograph, 5 cases illustrate how specialized testing can provide important information that can aid in diagnosis.

Abstract
Because of the ongoing epidemics of obesity and diabetes, nonalcoholic steatohepatitis (NASH) may become a leading indication for liver transplantation. There are concerns about the posttransplant survival of patients with NASH because of associated cardiovascular and metabolic risk factors. We aimed to determine recent trends in the proportion of patients undergoing transplantation for NASH-related cirrhosis in the United States and to estimate their posttransplant survival. We used data provided by the United Network for Organ Sharing for first-time adult cadaveric liver transplants performed in the United States between January 1, 1997 and October 31, 2010 (n = 53,738). The proportion of liver transplants performed for NASH-related cirrhosis increased dramatically from 1.2% in 1997-2003 to 7.4% in 2010 when NASH was the fourth most common indication for transplantation. The posttransplant survival of patients with NASH (n = 1810) at 1 (87.6%), 3 (82.2%), and 5 years (76.7%) was superior to the survival of patients with hepatocellular carcinoma, hepatitis C virus, alcoholic liver disease, acute hepatic necrosis, hemochromatosis, or cryptogenic liver disease and was inferior to the survival of only 4 groups of patients (those with primary biliary cirrhosis, primary sclerosing cholangitis, autoimmune hepatitis, or hepatitis B virus). In conclusion, NASH-related cirrhosis is increasing rapidly as an indication for liver transplantation in the United States and is associated with excellent posttransplant survival.

Abstract
UNLABELLED Elevated serum uric acid (UA) levels strongly reflect and may even cause oxidative stress, insulin resistance, and metabolic syndrome, which are risk factors for the progression of liver disease. We sought to determine whether serum UA levels are associated with the development of cirrhosis or the presence of elevated serum liver enzymes. We used cohort data from the first National Health and Nutrition Examination Survey (NHANES I) to determine whether the baseline serum UA level was associated with the incidence of hospitalization or death due to cirrhosis among 5518 participants during a mean follow-up of 12.9 years (range = 4-21 years) after the exclusion of the first 4 years of follow-up. We also used cross-sectional data from NHANES 1988-1994 (n = 10,993) and NHANES 1999-2006 (n = 6186) to determine whether the serum UA level was associated with elevated serum alanine aminotransferase (ALT) or gamma-glutamyl transferase (GGT), two markers of hepatic necroinflammation. Compared to persons in the lower third of the distribution of serum UA (<4.8 mg/dL), those in the top third (>6 mg/dL) had a higher risk of cirrhosis-related hospitalization or death [adjusted hazard ratio (AHR) = 2.8, 95% confidence interval (CI) =1.3-5.7], whereas the risk was not substantially increased in persons within the middle third (serum UA level = 2.6-4.8 mg/dL, AHR = 1.3, 95% CI = 0.6-2.7). A higher serum UA level was associated with greater mean serum ALT and GGT levels and a greater probability of elevated serum ALT and GGT. CONCLUSION The serum UA level is associated with the development of cirrhosis and the presence of elevated serum liver enzymes after adjustments for important causes and risk factors of chronic liver disease.

Abstract
The problem of separating single-wall carbon nanotubes (CNTs) by diameter and/or chirality is one of the greatest impediments toward the widespread application of these promising materials in nanoelectronics. In this paper, we describe a novel physical-chemical method for diameter-selective CNT separation that is both simple and effective and that allows up-scaling to large volumes at modest cost. Separation is based on size-selective noncovalent matching of an appropriate anchor molecule to the wall of the CNT, enabling suspension of the CNTs in solvents in which they would otherwise not be soluble. We demonstrate size-selective separation in the 1-2 nm diameter range using easily synthesized oligo-acene adducts as a diameter-selective molecular anchor. CNT field effect transistors fabricated from diameter-selected CNTs show markedly improved electrical properties as compared to nonselected CNTs.

Abstract
We describe a method to selectively position carbon nanotubes on Al2O3 and HfO2 surfaces. The method exploits the selective binding of alkylphosphonic acids to oxide surfaces with large isoelectric points (i.e. basic rather than acidic surfaces). We have patterned oxide surfaces with acids using both microcontact printing and conventional lithography. With proper choice of the functional end group (e.g., -CH3 or -NH2), nanotube adhesion to the surface can be either prevented or enhanced.
