Anti-tumor necrosis factor (aTNF) weaning strategy in juvenile idiopathic arthritis (JIA): does duration matter? Clin Rheumatol 2024; 43:1723-1733. [PMID: 38443603 DOI: 10.1007/s10067-024-06928-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 02/20/2024] [Accepted: 02/29/2024] [Indexed: 03/07/2024]
Abstract
BACKGROUND To compare outcomes of a short and long weaning strategy of anti-tumor necrosis factor (aTNF) in our prospective juvenile idiopathic arthritis (JIA) cohort. RESEARCH DESIGN AND METHODS JIA patients on subcutaneous adalimumab with at least 6 months of follow-up were recruited (May 2010-Jan 2022). Once clinical remission on medication (CRM) was achieved, adalimumab was weaned according to two protocols-short (every 4-weekly for 6 months and stopped) and long (extending dosing interval by 2 weeks for three cycles until 12-weekly intervals and thereafter stopped) protocols. Outcomes assessed were flare rates, time to flare, and predictors. RESULTS Of 110 JIA patients, 77 (83% male, 78% Chinese; 82% enthesitis-related arthritis) underwent aTNF weaning with 53% on short and 47% on long weaning protocol. The total flare rate during and after stopping aTNF was not different between the two groups. The time to flare after stopping aTNF was not different (p = 0.639). Positive anti-nuclear antibody increased flare risk during weaning in long weaning group (OR 7.0, 95%CI: 1.2-40.8). Positive HLA-B27 (OR 6.5, 95%CI: 1.1-30.4) increased flare risks after stopping aTNF. CONCLUSION Duration of weaning aTNF may not minimize flare rate or delay time to flare after stopping treatment in JIA patients. Recapture rates for inactive disease at 6 months remained high for patients who flared after weaning or discontinuing medication.

Taiwan ocular inflammation society consensus recommendations for the management of juvenile idiopathic arthritis-associated uveitis. J Formos Med Assoc 2024:S0929-6646(24)00110-4. [PMID: 38423923 DOI: 10.1016/j.jfma.2024.02.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 11/06/2023] [Accepted: 02/20/2024] [Indexed: 03/02/2024] Open
Abstract
We presented the development of a consensus guideline for managing juvenile idiopathic arthritis-associated uveitis (JIAU) in Taiwan, considering regional differences in manifestation and epidemiology. The Taiwan Ocular Inflammation Society (TOIS) committee formulated this guideline using a modified Delphi approach with two panel meetings. Recommendations were based on a comprehensive evidence-based literature review and expert clinical experiences, and were graded according to the Oxford Centre for Evidence-Based Medicine's "Levels of Evidence" guideline (March 2009). The TOIS consensus guideline consists of 10 recommendations in four categories: screening and diagnosis, treatment, complications, and monitoring, covering a total of 27 items. These recommendations received over 75% agreement from the panelists. Early diagnosis and a coordinated referral system between ophthalmologists and pediatric rheumatologists are crucial to prevent irreversible visual impairment in children with JIAU. However, achieving a balance between disease activity and medication use remains a key challenge in JIAU management, necessitating further clinical studies.

Clinical efficacy and nocebo effect following non-medical biosimilar switch in patients with inflammatory bowel disease: A prospective observational study. Dig Liver Dis 2024; 56:35-42. [PMID: 37419726 DOI: 10.1016/j.dld.2023.06.022] [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: 05/10/2023] [Revised: 06/04/2023] [Accepted: 06/20/2023] [Indexed: 07/09/2023]
Abstract
BACKGROUND We aimed to evaluate clinical efficacy, biomarker activity, therapeutic drug monitoring (TDM), adverse events (AEs), and nocebo effect in inflammatory bowel disease (IBD) patients who underwent non-medical biosimilar switching. METHODS A prospective observational study of consecutive IBD patients who underwent biosimilar switch. Disease activity, biomarkers, TDM, and AEs, including the nocebo effect were captured 8 weeks before switch, at the time of switch (baseline),12 and 24 weeks after the switch. RESULTS 210 patients were included [81.4% had Crohn's disease (CD), the median age at inclusion: 42 years (IQR 29-61)]. There was no significant difference in the rates of clinical remission at week 8 before switch, baseline, week12, and 24 after switch: 89.0%,93.4%,86.3%,and 90.8%,p = 0.129. The biomarker remission rates were not significantly different; CRP:81.3%,74.7%,81.2%,73.0%,p = 0.343; fecal calprotectin: 78.3%,74.5%,71.7%,76.3%,p = 0.829. The rates of maintaining therapeutic levels (84.7%,83.9%,83.0%,85.3%,p = 0.597) and prevalence of positive anti-drug antibodies remained unchanged. Drug persistence at 12 week of switch was 97.1%, regardless of disease phenotype and originator. The nocebo effect was observed in 13.3%. The discontinuation rate was 4.8%. CONCLUSION Despite a significant number of early nocebo complaints within the first 6 months after the biosimilar switch, no significant changes were found in clinical efficacy, biomarkers, therapeutic drug level, or anti-drug antibodies.

Suboptimal response to tumor necrosis factor antagonists in inflammatory bowel disease in Latin America: EXPLORE LATAM study. GASTROENTEROLOGIA Y HEPATOLOGIA 2024; 47:51-62. [PMID: 37062500 DOI: 10.1016/j.gastrohep.2023.04.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 03/29/2023] [Accepted: 04/03/2023] [Indexed: 04/18/2023]
Abstract
OBJECTIVE Data on anti-tumor necrosis factor (anti-TNF) treatment and suboptimal response (SOR) among patients with inflammatory bowel diseases (IBD) in Latin America (LATAM) are scarce. This study evaluated the incidence and indicators of SOR to anti-TNF therapy in patients with ulcerative colitis (UC) and Crohn's disease (CD) from Argentina, Colombia and Mexico. PATIENTS AND METHODS We performed retrospective analysis of data from LATAM patients of the EXPLORE study (NCT03090139) including adult patients with IBD who initiated anti-TNF therapy between March 2010 to March 2015. The cumulative incidence of SOR to first-line anti-TNF therapy was assessed. A physician survey to assess barriers to anti-TNF therapies was also carried out. RESULTS We included 185 IBD patients (UC/CD: 99/86) treated with first-line anti-TNF from Argentina (38 UC; 40 CD), Colombia (21 UC; 25 CD) and Mexico (40 UC; 21 CD). 36.4% of patients with UC and 46.5% of patients with CD experienced SOR to anti-TNF therapy during the median (interquartile range) observational period: 49.0 months (37.2-60.1) in UC, and 50.0 months (40.9-60.1) in CD. The most common indicator of SOR among patients was augmentation of non-biologic therapy (UC: 41.7%; CD: 35.0%). Affordability and late referral to IBD specialist care centers were the most common barriers to anti-TNF therapies. CONCLUSIONS SOR to anti-TNF therapy was common in LATAM IBD patients, where augmentation with non-biologic therapy represented the most frequent indicator of SOR across indications. Our findings contribute to the current evidence on the unmet needs associated with anti-TNF in LATAM.

Size Matters! Anti-HBs Titer and HBV Reactivation During Anti-TNF Therapy. Dig Dis Sci 2023; 68:4511-4520. [PMID: 37891440 DOI: 10.1007/s10620-023-08141-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Accepted: 10/02/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND AND AIMS We and others have previously described that hepatitis B surface antibody (anti-HBs) seems to protect against clinically significant HBV reactivation in cohort studies of patients undergoing anti-tumor necrosis factor (TNF) therapy. However, there were too few cases of HBV reactivation within cohort studies to assess the role of anti-HBs titer on reactivation. The purpose of this study was to systematically review the correlation between anti-HBs titer and the degree of clinically relevant HBV reactivation in patients undergoing anti-TNF therapy. METHODS AND RESULTS We systemically reviewed all studies discussing anti-TNF therapy in patients with resolved HBV infection, defined as hepatitis surface antigen (HBsAg) negative and hepatitis B core antibody (anti-HBc) positive. We identified a total of 48 cases of reactivation from 5 cohort studies and 10 case reports or case series; 21 were anti-HBs negative, 7 were only reported as anti-HBs positive, 16 were anti-HBs positive with titer below 100, and 4 were anti-HBs positive with titer above 100. HBsAg sero-reversion was dominantly seen in patients with negative, low and/or declining anti-HBs titers. There was a significant trend toward less clinically relevant form of reactivation with increase in baseline anti-HBs titer (p = 0.022). CONCLUSION Anti-HBs titers greater than 100 iU/L protect against clinically relevant HBV reactivation, while patients with low anti-HBs titers or negative anti-HBs had more clinically relevant HBV reactivation and higher rates of HBsAg sero-reversion. This suggests the importance of baseline quantitative anti-HBs prior to starting anti-TNF therapy and consideration vaccination for boosting anti-HBs titers prior to and/or during therapy.

Serum albumin is the strongest predictor of anti-tumor necrosis factor nonresponse in inflammatory bowel disease in resource-constrained regions lacking therapeutic drug monitoring. Intest Res 2023; 21:460-470. [PMID: 36926698 PMCID: PMC10626021 DOI: 10.5217/ir.2022.00128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 01/03/2023] [Accepted: 01/09/2023] [Indexed: 03/18/2023] Open
Abstract
BACKGROUND/AIMS Evidence on predictors of primary nonresponse (PNR), and secondary loss of response (SLR) to anti-tumor necrosis factor (anti-TNF) agents in inflammatory bowel disease is scarce from Asia. We evaluated clinical/biochemical/molecular markers of PNR/SLR in ulcerative colitis (UC) and Crohn's disease (CD). METHODS Inflammatory bowel disease patients treated with anti-TNF agents (January 2005-October 2020) were ambispectively included. Data concerning clinical and biochemical predictors was retrieved from a prospectively maintained database. Immunohistochemistry for expression of oncostatin M (OSM), OSM receptor (OSM-R), and interleukin-7 receptor (IL-7R) were done on pre anti-TNF initiation mucosal biopsies. RESULTS One-hundred eighty-six patients (118 CD, 68 UC: mean age, 34.1±13.7 years; median disease duration at anti-TNF initiation, 60 months; interquartile range, 28-100.5 months) were included. PNR was seen in 17% and 26.5% and SLR in 47% and 28% CD and UC patients, respectively. In CD, predictors of PNR were low albumin (P<0.001), postoperative recurrence (P=0.001) and high IL-7R expression (P<0.027) on univariate; and low albumin alone (hazard ratio [HR], 0.09; 95% confidence interval [CI], 0.03-0.28; P<0.001) on multivariate analysis respectively. Low albumin (HR, 0.31; 95% CI, 0.15-0.62; P=0.001) also predicted SLR. In UC, predictors of PNR were low albumin (P<0.001), and high C-reactive protein (P<0.001), OSM (P<0.04) and OSM-R (P=0.07) stromal expression on univariate; and low albumin alone (HR, 0.11; 95% CI, 0.03-0.39; P=0.001) on multivariate analysis respectively. CONCLUSIONS Low serum albumin at baseline significantly predicted PNR in UC and PNR/SLR in CD patients. Mucosal markers of PNR were high stromal OSM/OSM-R in UC and high IL-7R in CD patients.

A case series of intracardiac thrombi and vascular involvement in pediatric Behçet's disease. Rheumatol Int 2023; 43:1161-1171. [PMID: 36890395 DOI: 10.1007/s00296-023-05292-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Accepted: 02/21/2023] [Indexed: 03/10/2023]
Abstract
To evaluate the general characteristics of pediatric Behçet's disease (BD) patients with thrombus and to present the clinical features, treatment responses and prognosis of patients with intracardiac thrombus. The clinical characteristics and outcomes of 15 patients with thrombus among 85 pediatric BD patients followed in the Department of Pediatric Rheumatology were evaluated retrospectively. Of the 15 BD patients with thrombus, 12 (80%) were male, 3 (20%) were female. The mean age at diagnosis was 12.9 ± 1.1 years. Thrombus was present at the time of diagnosis in 12 patients (80%), while thrombus developed in three patients within the first three months after diagnosis. The most common site of thrombus was the central nervous system (n = 9, 60%), followed by deep vein thrombus (n = 6, 40%) and pulmonary artery thrombus (n = 4, 26.6%). Three male patients (20%) developed intracardiac thrombus. The overall intracardiac thrombus rate in the 85 patients was 3.5%. Two of the three patients had thrombus in the right, and one had thrombus in the left heart cavity. In addition to steroids, 2 of the 3 patients received cyclophosphamide, while the patient with thrombus localized in the left heart cavity was given infliximab. In the follow-up, the two patients with thrombus in the right heart cavity were switched to infliximab because of resistance to cyclophosphamide. Complete resolution was observed in 2 of the 3 patients on infliximab; a significant reduction in the thrombus of the other patient was achieved. Intracardiac thrombus is a rare presentation of cardiac involvement in BD. It is usually observed in males and in the right heart. Although steroids and immunosuppressive agents such as cyclophosphamide are recommended as first-line treatment, favorable outcomes can be achieved with anti-TNFs in resistant cases.

Intestinal complications in patients with Crohn’s disease in the Brazilian public healthcare system between 2011 and 2020. World J Clin Cases 2023; 11:3224-3237. [PMID: 37274050 PMCID: PMC10237144 DOI: 10.12998/wjcc.v11.i14.3224] [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: 01/09/2023] [Revised: 02/27/2023] [Accepted: 04/06/2023] [Indexed: 05/16/2023] Open
Abstract
BACKGROUND This is a secondary database study using the Brazilian public healthcare system database.
AIM To describe intestinal complications (ICs) of patients in the Brazilian public healthcare system with Crohn’s disease (CD) who initiated and either only received conventional therapy (CVT) or also initiated anti-tumor necrosis factor (anti-TNF) therapy between 2011 and 2020.
METHODS This study included patients with CD [international classification of diseases – 10th revision (ICD-10): K50.0, K50.1, or K50.8] (age: ≥ 18 years) with at least one claim of CVT (sulfasalazine, azathioprine, mesalazine, or methotrexate). IC was defined as a CD-related hospitalization, pre-defined procedure codes (from rectum or intestinal surgery groups), and/or associated disease (pre-defined ICD-10 codes), and overall (one or more type of ICs).
RESULTS In the 16809 patients with CD that met the inclusion criteria, the mean follow-up duration was 4.44 (2.37) years. In total, 14697 claims of ICs were found from 4633 patients. Over the 1- and 5-year of follow-up, 8.3% and 8.2% of the patients with CD, respectively, presented at least one IC, of which fistula (31%) and fistulotomy (48%) were the most commonly reported. The overall incidence rate (95%CI) of ICs was 6.8 (6.5–7.04) per 100 patient years for patients using only-CVT, and 9.2 (8.8–9.6) for patients with evidence of anti-TNF therapy.
CONCLUSION The outcomes highlighted an important and constant rate of ICs over time in all the CD populations assessed, especially in patients exposed to anti-TNF therapy. This outcome revealed insights into the real-world treatment and complications relevant to patients with CD and highlights that this disease remains a concern that may require additional treatment strategies in the Brazilian public healthcare system.

Infliximab vs adalimumab: Points to consider when selecting anti-tumor necrosis factor agents in pediatric patients with Crohn’s disease. World J Gastroenterol 2023; 29:2784-2797. [PMID: 37274072 PMCID: PMC10237103 DOI: 10.3748/wjg.v29.i18.2784] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 03/20/2023] [Accepted: 04/17/2023] [Indexed: 05/11/2023] Open
Abstract
Biologic agents with various mechanisms against Crohn’s disease (CD) have been released and are widely used in clinical practice. However, two anti-tumor necrosis factor (TNF) agents, infliximab (IFX) and adalimumab (ADL), are the only biologic agents approved by the Food and Drug Administration for pediatric CD currently. Therefore, in pediatric CD, the choice of biologic agents should be made more carefully to achieve the therapeutic goal. There are currently no head-to-head trials of biologic agents in pediatric or adult CD. There is a lack of accumulated data for pediatric CD, which requires the extrapolation of adult data for the positioning of biologics in pediatric CD. From a pharmacokinetic point of view, IFX is more advantageous than ADL when the inflammatory burden is high, and ADL is expected to be advantageous over IFX in sustaining remission in the maintenance phase. Additionally, we reviewed the safety profile, immunogenicity, preference, and compliance between IFX and ADL and provide practical insights into the choice of anti-TNF therapy in pediatric CD. Careful evaluation of clinical indications and disease behavior is essential when prescribing anti-TNF agents. In addition, factors such as the efficacy of induction and maintenance of remission, safety profile, immunogenicity, patient preference, and compliance play an important role in evaluating and selecting treatment options.

Dose intensification strategy influences infliximab pharmacokinetics but not clinical response after the same number of doses. J Gastroenterol Hepatol 2023; 38:724-732. [PMID: 36692034 DOI: 10.1111/jgh.16133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Revised: 01/16/2023] [Accepted: 01/20/2023] [Indexed: 01/25/2023]
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 AND AIMS Few population-based studies have investigated the long-term colectomy rates of ulcerative colitis (UC). We aimed to assess the colectomy rates over 40 years of different therapeutic eras in a prospective population-based inception cohort from Veszprem Province, Western Hungary. METHODS Patient inclusion lasted between January1,1977, and December31, 2018. Patient follow-up ended December 31,2020. Colectomy rates and disease course were examined in three different eras based on the time of UC diagnosis; cohort-A(1977-1995),cohort-B(1996-2008), and cohort C(2009-2018). RESULTS A total of 1,370 incident UC patients were included (male 51.2%,median age at diagnosis:37 years). Median follow-up was 17 years (IQR 9-24); 87 patients(6.4%) underwent colectomy. The cumulative probability of colectomy in the total population was 2.6%(95%CI 2.2-3.0), 4.2%(95%CI 3.6-4.8), 7.0%(95%CI 6.2-7.8), and 10.4%(95%CI 9.1-11.7) after 5, 10, 20, and 30 years, respectively. The proportion of extensive colitis at diagnosis increased over time (24.2%/24.3%/34.9% in cohorts A/B/C,p=0.001). Overall exposure to immunomodulators (11.3%/20.9%/34.4% in cohorts A/B/C,p<0.001), as well as the probability for biological therapy initiation increased over time; 0%/ 3.3%(95%CI 2.6-4.0)/ 13.9%(95%CI 12.1-15.7), p<0.001. There were no statistically significant differences in the cumulative probability of colectomies between cohorts A/B/C; 1.7% (95%CI 1.0-2.4), 2.5%(95%CI 1.9-3.1), and 3.7%(95%CI 2.7-4.7) after 5 years; 3.5%(95%CI 2.5-4.5), 4.2%(95%CI 3.4-5.0), and 4.5%(95%CI 3.3-5.7) after 10 years; and 7.5% (95%CI 6.1-8.9) and 6.3% (95%CI 5.2-7.4) in cohorts A/B after 20 years (Log-rank=0.588). Extensive colitis (HR;2.24:95%CI 1.55-3.23) and continuous active disease activity (HR;6.36:95%CI 3.46-11.67) were independent predictors for colectomy. CONCLUSION No differences in colectomy rates have been observed in the incident UC patients over 40 years despite increasing use of immunomodulators and biological therapies.

Abstract
BACKGROUND Anti-tumor necrosis factor (anti-TNF) monoclonal antibody, infliximab, is the primary therapeutic modality for patients with Crohn's disease (CD) and ulcerative colitis (UC), refractory to conventional therapy. Biosimilars of infliximab have been shown to have equivalent efficacy to originator infliximab. We compared the safety and efficacy of infliximab biosimilar with the originator in Indian patients with inflammatory bowel disease (IBD). METHODS Patients with IBD treated with either originator or biosimilar infliximab from January 2005 to October 2020 were included in this retrospective analysis. The safety and efficacy of originator or biosimilar infliximab in inducing and maintaining clinical remission at weeks 14 and 52 for CD and UC were evaluated. Disease activity was estimated at baseline, after induction therapy, after 1 year of treatment, and during 12 months of follow-up. RESULTS In all, 137 patients (82 CD; 55 UC) were included, of whom 102 were on originator, and 35 patients received biosimilar. In biosimilar group, clinical response and remission rates at weeks 14 and 52 were 84.2%, 58% and 68.4%, 52.6% in CD and 81.2%, 56.2% and 68.7%, 62.5% in UC patients, respectively. Among patients who were on originator, clinical response and remission rates at weeks 14 and 52 were 79.4%, 46% and 57.1%, 43% in CD and 72%, 64.1% and 66.7%, 56.4% in UC patients, respectively. Thirty-three (24.1%) patients experienced adverse events; eighteen developed tuberculosis (TB), of whom 17 received originator and one patient received biosimilar. CONCLUSIONS Infliximab biosimilar is comparable to originator infliximab in terms of safety profile and its efficacy in inducing and maintaining remission in patients with IBD.

Response to COVID-19 vaccine is reduced in patients with inflammatory bowel disease, but improved with additional dose. J Gastroenterol Hepatol 2022; 38:44-51. [PMID: 36066279 PMCID: PMC9537921 DOI: 10.1111/jgh.16001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 08/28/2022] [Accepted: 09/04/2022] [Indexed: 01/18/2023]
Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) vaccination is recommended for patients with inflammatory bowel disease (IBD); however, suppressed immune responses have been reported for fully vaccinated patients under immunosuppressive therapy, mainly from Western countries. We prospectively analyzed antibody titers of IBD patients in Asia induced by two-dose and additional dose of messengerRNA COVID-19 vaccine. METHODS After measuring high-affinity antibody titers, factors associated with antibody titers were identified by multiple regression analyses using the following covariates: sex, age (≥60 or <60 years), disease type (Crohn's disease or ulcerative colitis), vaccine type (BNT162b2 or mRNA-1273), time from second/third vaccination, molecular-targeted agent (anti-tumor necrosis factor [TNF] agents, ustekinumab, vedolizumab, tofacitinib, or no molecular-targeted agents), thiopurine, steroid, and 5-aminosalicylic acid. RESULTS Among 409 patients analyzed, mean titer was 1316.7 U/mL (SD, 1799.3); 403 (98.5%) were judged to be seropositive (≥0.8 U/mL), and 389 (95.1%) had neutralizing antibodies (≥15 U/mL). After the third vaccination, mean titer raised up to 21 123.8 U/mL (SD, 23 474.5); all 179 were seropositive, and 178 (99.4%) had neutralizing antibodies. In 248 patients with genetic data, there was no difference in mean titer after two/third doses between carriers and non-carriers of HLA-A24 associated with severe disease during COVID-19 infection. A multiple regression analyses using covariates revealed that older age, vaccine type (BNT162b2), time from second/third dose, anti-TNF agent, tofacitinib, and thiopurine were independently associated with lower antibody titers. CONCLUSIONS Our findings further support the recommendation for COVID-19 vaccination in patients under immunosuppressive therapy, especially additional third dose for patients receiving anti-TNF agents and/or thiopurine or tofacitinib.

Efficacy and Safety of Certolizumab Pegol in Japanese Patients with Generalized Pustular Psoriasis and Erythrodermic Psoriasis: 52-Week Results. Dermatol Ther (Heidelb) 2022; 12:1397-1415. [PMID: 35622315 PMCID: PMC9209588 DOI: 10.1007/s13555-022-00741-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 04/26/2022] [Indexed: 01/14/2023] Open
Abstract
Introduction We report an exploratory analysis of the efficacy and safety of certolizumab pegol (CZP) in Japanese patients with generalized pustular psoriasis (GPP) and erythrodermic psoriasis (EP) (NCT03051217). Methods Patients ≥ 20 years with GPP or EP were randomized 1:1 to open-label CZP 400 mg every 2 weeks (Q2W) or 200 mg Q2W (400 mg weeks 0/2/4) for 16 weeks; patients who achieved “much improved” or “very much improved” on the Global Improvement Score (GIS; for GPP) or a PASI 50 response (≥ 50% reduction from baseline Psoriasis Area and Severity Index; for EP) continued to week 52. Efficacy outcomes assessed included Clinical Global Impression of Improvement (CGI-I), Dermatology Life Quality Index (DLQI 0/1), and Itch Numeric Rating Scale (INRS 0). GIS and Japanese Dermatological Association (JDA) severity index were assessed in patients with GPP, and PASI and Physician’s Global Assessment (PGA) in patients with EP. Treatment-emergent adverse events (TEAEs) were evaluated through weeks 0–52. Results Of 22 patients randomized, 19 completed week 52. At week 16, all reported outcomes improved with both CZP doses and were generally maintained through week 52. At week 52, 6/7 GPP and 12/12 EP patients achieved CGI-I response (“improved” or “remission”). Also, 4/7 GPP and 7/12 EP patients achieved DLQI 0/1; 2/7 GPP and 2/12 EP patients achieved INRS 0. Meanwhile, 6/7 patients with GPP achieved GIS response, and JDA severity index was reduced from baseline. We found that 9/12 and 5/12 patients with EP achieved PASI 90 and PGA 0/1, respectively. Overall, three serious TEAEs were reported in three CZP 400 mg Q2W-treated patients. Conclusion CZP treatment over 16 weeks improved the signs and symptoms of GPP and EP, and improvements were maintained through week 52. No new safety signals were identified.

Abstract
The increasing incidence of inflammatory bowel disease (IBD) globally has redirected the healthcare system's focus towards safe and affordable pharmacological interventions. The inception of anti-tumor necrosis factor-α (TNF-α) had resulted in a trend shift from surgical interventions. However, as the patents of approved anti-TNF-α drugs expire, biological copies of the many approved products are in the pipeline. The most commonly used biosimilar for IBD has been infliximab, followed by Adalimumab biosimilars which have been approved in major countries across the world. Although biosimilars are approved on the basis of similarity of their reference product, the lack of real-world evidence of its safety in ulcerative colitis and Crohn’s disease patients has contributed to physicians’ hesitancy. However, biosimilars are expected to reduce treatment costs and provide economic benefits.

Indicators of suboptimal response to anti-tumor necrosis factor therapy in patients from China with inflammatory bowel disease: results from the EXPLORE study. BMC Gastroenterol 2022; 22:44. [PMID: 35120446 PMCID: PMC8817491 DOI: 10.1186/s12876-021-02074-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Accepted: 12/10/2021] [Indexed: 02/08/2023] Open
Abstract
Background Prevalence of inflammatory bowel disease (IBD) is increasing in China. The EXPLORE study evaluated the incidence and indicators of suboptimal responses to first-line anti-tumor necrosis factor (TNF) in patients with ulcerative colitis (UC) or Crohn’s disease (CD). We present results for the mainland China subgroup. Methods A retrospective chart review was performed in adults with IBD at 10 centers in mainland China who initiated anti-TNF therapy between 01 March 2010 and 01 March 2015. The cumulative incidence of suboptimal response to first-line anti-TNF therapy was assessed over 24 months using the Kaplan–Meier method. Indicators of suboptimal response were: dose escalation, discontinuation, augmentation with non-biologic therapy, or IBD-related surgery/hospitalization. At site initiation, a survey was conducted with participating physicians to identify barriers to anti-TNF use. Results Of 287 patients (72% male) examined, 16/35 (45.7%) with UC and 123/252 (48.8%) with CD experienced a suboptimal response to first-line anti-TNF therapy at any point during the observation period (median 27.6 and 40.0 months, respectively). At 1 and 2 years post anti-TNF initiation, the cumulative incidence of suboptimal response was 51.4% and 75.7% for UC and 45.4% and 57.0% for CD, respectively. Median time to first suboptimal response was 7.2 months for UC and 14.3 months for CD. The most frequent indicator of suboptimal response was discontinuation of anti-TNF therapy (9/16, 56.3%) for UC and IBD-related hospitalization for CD (69/123, 56.1%) followed by augmentation with non-biologic therapy for both cohorts (5/16, 31.3% for UC and 28/123, 22.8% for CD). Dose escalation was the least frequent indicator of suboptimal response to anti-TNF therapy (CD: 4/123, 3.3%; UC: not cited as an indicator). The cumulative incidence of suboptimal response within 4 months of first-line anti-TNF therapy (primary non-response) was over 30% in both cohorts. Financial reasons and reimbursement were identified by surveyed physicians as the most common barriers to prescribing an anti-TNF therapy. Conclusions Over one-half of patients with IBD are at risk of experiencing a suboptimal response to first-line anti-TNF therapy at 2 years post-initiation in China. This study highlights a substantial unmet need associated with anti-TNF therapies in China. (Clinicaltrials.gov identifier: NCT03090139).

Abstract
BACKGROUND Frailty may be a risk factor for complications in inflammatory bowel diseases (IBD) patients. We examined the impact of treatment on IBD patients who were frail prior to treatment and identified predictors of post-treatment change in frailty. METHODS In an electronic health record-based cohort of IBD patients initiating anti-tumor necrosis factor (TNF)-α agents, we applied a validated claims-based frailty index to determine frailty in the 1 year prior to and after treatment initiation. We characterized treatment non-response using a composite outcome of IBD-related hospitalization, surgery, change in therapy, or initiation of systemic steroids. We constructed multivariable logistic regression models to identify determinants of post-treatment frailty. RESULTS The 1210 patients initiating anti-TNF therapy had a median age of 30 years; 20% were ≥ 50 years. In the first year after anti-TNF initiation, 40% were non-responders. Many more treatment non-responders were frail in the year following treatment compared with treatment responders (27% vs 7%, p < 0.001). Pre-treatment frailty (OR 2.01, 95% CI 1.35-3.00) and prior IBD-related hospitalization (OR 1.63, 95% CI 1.15-2.30) were independently predictive of higher likelihood of post-treatment frailty. Therapy response was associated with a lower likelihood (OR 0.24, 95% CI 0.16-0.34) of post-treatment frailty. Nearly 85% of patients who were frail prior to treatment demonstrated improvement in frailty following treatment CONCLUSIONS: Response to anti-TNF therapy is an important determinant of post-treatment frailty in patients with IBD. Our findings suggest that effectively treating inflammatory states in older patients with IBD may improve frailty.

Abstract
Malignancies constitute the second cause of death in patients with inflammatory bowel diseases (IBD), after cardiovascular diseases. Although it has been postulated that IBD patients are at greater risk of colorectal cancer compared to the general population, lately there has been evidence supporting that this risk is diminishing over time as a result of better surveillance, while the incidence of extraintestinal cancers (EICs) is increasing. This could be attributed either to systemic inflammation caused by IBD or to long-lasting immunosuppression due to IBD treatments. It seems that the overall risk of EICs is higher for Crohn’s disease patients and it is mainly driven by skin cancers, and liver-biliary cancers in patients with IBD and primary sclerosing cholangitis. The aims of this review were first to evaluate the prevalence, characteristics, and risk factors of EICs in patients with IBD and second to raise awareness regarding a proper surveillance program resulting in early diagnosis, better prognosis and survival, especially in the era of new IBD treatments that are on the way.

Biologic Therapies and Small Molecules for the Management of Non-Infectious Scleritis: A Narrative Review. Ophthalmol Ther 2021; 10:777-813.

Abstract
Scleritis refers to a wide spectrum of ocular conditions ranging from mild to sight-threatening scleral inflammation that may compromise visual function and threaten the anatomical integrity of the ocular globe. Most aggressive forms like necrotizing or posterior scleritis are often difficult-to-treat cases, refractory to conventional treatment. The association with systemic diseases, namely rheumatoid arthritis, Sjögren syndrome, granulomatosis with polyangiitis, and relapsing polychondritis, may have prognostic implications as well. A better understanding of the pathogenesis of ocular inflammatory diseases have paved the way to more effective and targeted treatment approaches. In this regard, a growing body of evidence supports the potential role of biologic agents in the management of non-infectious scleral inflammation, either idiopathic or in a background of immune-mediated systemic disorders. Biologic agents such as anti-tumor necrosis factor agents, interleukin-1 and interleukin-6 inhibitors as well as CD20 blockade have displayed promising results. More specifically, several studies have reported their ability to control scleral inflammation, reduce the overall scleritis relapses, and allow a glucocorticoid-sparing effect while being generally well tolerated. Anecdotal reports have also been described with other biologic agents including abatacept, ustekinumab, daclizumab, and alemtuzumab as well as targeted small molecules such as tofacitinib. Further studies are warranted to fully elucidate the role of biologic agents in non-infectious scleritis and investigate specific areas with the aim to administer treatments in the context of personalized medicine. This review summarizes the available data regarding clinical trials, small pilot studies, and real-life experience of the last two decades reporting the use of biologic agents in the management of non-infectious scleritis.

Rheumatol Ther 2021; 8:1603-1616.

Abstract
Introduction The aim of this work is to perform a systematic review and meta-analysis of anti-tumor necrosis factor (anti-TNF) and anti-interleukin-17 (anti-IL-17) trials for spondyloarthritis, psoriatic arthritis, and psoriasis comparing rates of inflammatory bowel disease (IBD) events compared to placebo. Methods MEDLINE, EMBASE, and The Cochrane Library were searched for double-blind, randomized placebo-controlled anti-TNF and anti-IL-17 trials of included diseases. Inflammatory bowel disease events from the RCT period were pooled and meta-analyzed using statistical methods suitable for low-event-rate meta-analysis (Peto’s, Mantel–Haenszel, hypergeometric-normal model, and Shuster-Guo-Skyler). When observed data were insufficient, we performed an exploratory sensitivity analysis to compare methods. Results We identified 9551 original papers, and included 96 publications: 65 anti-TNF and 31 anti-IL-17 trials, containing 21 new and 12 flare IBD events in 28,209 participants. New IBD on anti-IL-17 occurred 0.23/100 patient-years (PY) in psoriasis, 0.61/100 PY in PsA and 1.63/100 PY in spondyloarthritis, rates similar to observational cohorts, and less commonly on anti-TNF (0/100 PY, 0/100 PY, 0.32/100 PY, respectively). No evidence of difference between groups was found, with wide CI from many pooled counts of zero, especially in placebo arms. Conclusions IBD events were rare, occurring at rates similar to biologic-naive groups. We could not find statistically significant differences in risk of new or recurrent IBD between treatment and control groups using selected meta-analytical methods for low event rate scenarios. Meta-analyses of this topic require more IBD events, ideally without pooling heterogeneous groups. Larger, thoroughly reported trials with systematic and detailed safety reporting are required to improve risk estimation and to make accurate inferences.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by articular and extra-articular manifestations. Among extra-articular involvement, rheumatoid meningitis (RM) is a rare condition, which may exhibit variable symptoms including headache, focal and/or generalized neurologic deficits. It may develop as the preceding manifestation of RA or occur at any time of the disease course. Some drugs used for the treatment of RA may give rise to aseptic meningitis or create a tendency to infectious meningitis due to their immunosuppressive effect. All these possibilities may lead to difficulties in the differential diagnosis. Achieving a diagnosis in a short time is crucial in terms of prognosis. Here, we would like to report a case with longstanding RA manifested by left-sided weakness and seizure shortly after initiating etanercept (ETA) therapy. ETA-induced meningitis was confirmed with appropriate diagnostic tools. Our aim with this case-based review is to attract the attention of this rare condition and discuss diagnostic challenges.

Abstract
Background and Aims The majority of patients treated with anti-tumor necrosis factor (TNF) therapy develop anti-drug antibodies (ADAs), which might result in loss of treatment efficacy. Strict guidelines on measuring trough levels (TLs) and ADA in clinical routine do not exist. To provide real-world data, we took advantage of our tertiary inflammatory bowel disease (IBD) center patient cohort and determined indicators for therapeutic drug monitoring (TDM) and actual consequences in patient care. Methods We retrospectively collected clinical data of 104 IBD patients treated with infliximab or adalimumab in our IBD clinic. Patients with TL and ADA measurements between June 2015 and February 2018 were included. Results The main reason for determining TL was increased clinical disease. Subtherapeutic TLs were found in 33 patients, therapeutic TLs in 33 patients, and supratherapeutic TLs in 38 patients. Adjustments in anti-TNF therapy occurred more frequently (p = 0.01) in patients with subtherapeutic TL (24 of 33 patients; 73%) as compared to patients with therapeutic and supratherapeutic TLs (26 of 71 patients; 37%). No correlation could be found between TL and disease activity (p = 0.16). Presence of ADA was found in 16 patients, correlated with the development of infusion reactions (OR: 10.6, RR: 5.4, CI: 2.9-38.6), and was associated with subtherapeutic TL in 15 patients (93.8%). Treatment adaptations were based on TL and/or ADA presence in 36 of 63 patients. Conclusions TDM showed significant treatment adaptations in patients with subtherapeutic TL. Conversely, in patients with therapeutic and supratherapeutic TLs, reasons for adaptations were based on considerations other than TL, such as clinical disease activity. Further studies should focus on decision-making in patients presenting with supratherapeutic TL in remission.

Abstract
BACKGROUND Incidence of inflammatory bowel disease (IBD) is increasing in newly industrialised countries (NICs); however, data on suboptimal response to anti-tumor necrosis factor (anti-TNF) agents are limited. OBJECTIVES To assess incidence and indicators of suboptimal response to first anti-TNF therapy in IBD patients in NICs. METHODS A chart review was conducted in ten countries from Asia-Pacific (APAC), Latin America (LatAm), and Russia and the Middle East (RME) regions among patients diagnosed with ulcerative colitis (UC) or Crohn's disease (CD), initiating anti-TNF therapy in 2010-2015. The cumulative incidence of suboptimal response to anti-TNF therapy was assessed using the following indicators: dose escalation or discontinuation, augmentation with non-biologic therapy, IBD-related hospitalization, or surgery. RESULTS The study included 1,674 patients (570 UC; 1,104 CD). At 24 months, 32.9% of UC (APAC: 45.1%; LatAm: 38.2%; RME: 23.8%) and 41.2% of CD patients (APAC: 54.1%; LatAm: 42.5%; RME: 29.5%) had experienced suboptimal response. The most frequent first indicator was non-biologic therapy augmentation in LatAm (41.7%), IBD-related hospitalization in RME (UC: 50.7%; CD:37.3%) and in APAC for CD (39.1%), and anti-TNF discontinuation in APAC for UC (38.3%). CONCLUSION Suboptimal response to anti-TNF agents is common in IBD patients in NICs. Observed regional differences in the incidence and indicators may reflect local practice and anti-TNF restrictions in IBD management. NCT REGISTRATION NUMBER NCT03090139.

Abstract
BACKGROUND Head-to-head comparison studies evaluating the effectiveness and tolerability of anti-tumor necrosis factor (anti-TNF) drugs in inflammatory bowel disease patients are lacking. AIM To compare the effectiveness and tolerability of anti-TNF-α drugs used in clinical practice in a cohort of patients with moderate-to-severe ulcerative colitis (UC). METHODS Retrospectively, 122 UC patients treated with infliximab (IFX) originator and biosimilar, adalimumab (ADA), and golimumab (GOL) were included. We performed an ITT analysis to evaluate clinical response and remission, steroid-free clinical remission, and endoscopy response according to the different time points of the follow-up. Baseline and post induction predictor factors of these outcomes were evaluated using multivariate logistic regression models. Moreover, a propensity score-based weighting analysis was performed. Data were analyzed using R and STATA11 software. RESULTS The overall clinical response was 77% after induction, 81.4% at 30 weeks, and 76.9% at 52 weeks, while the steroid-free clinical remission was 39.7, 46, and 54.6%, respectively. After induction, a higher rate of treatment failure was observed in the GOL group. At the end of follow-up, lower rates of steroid-free clinical remission and clinical response were obtained by GOL. At week 52, endoscopic response was achieved by 46.5% of the population. CONCLUSIONS Among the different anti-TNF treatments, moderate-to-severe UC seems to respond better to IFX and ADA, whereas GOL seems to be less effective, despite a similar good safety profile.

[PMID: 31791908 DOI: 10.1016/j.resinv.2019.11.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2019] [Revised: 10/30/2019] [Accepted: 11/05/2019] [Indexed: 11/23/2022]
Abstract
BACKGROUND We evaluated immune reconstitution inflammatory syndrome (IRIS) in the lung in non-human immunodeficiency virus (HIV) patients. METHODS We reviewed articles related to IRIS occurrence in the lung in non-HIV patients using a PubMed search. The keywords used for the search were "immune reconstitution syndrome" and "non-HIV." Only patients with lung involvement were included. Those with suggested IRIS caused by white blood cell recovery were excluded. RESULTS There were 37 cases of IRIS in the lung in non-HIV patients. Complicating infections included tuberculosis (n = 17), histoplasmosis (n = 9), aspergillosis (n = 5), cryptococcosis (n = 4), and Pneumocystis pneumonia (n = 2). We also evaluated the underlying diseases, IRIS pathogenesis, management, and prognosis. IRIS was most commonly encountered in patients treated with anti-tumor necrosis factor (TNF) antibody who developed disseminated or extrapulmonary tuberculosis, leading to treatment discontinuation. CONCLUSIONS The diagnosis and management of IRIS in the lung in non-HIV patients should be investigated further, especially in the era of anti-TNF treatment.

Efficacy and safety of intravenous golimumab plus methotrexate in patients with rheumatoid arthritis aged < 65 years and those ≥ 65 years of age. Arthritis Res Ther 2019; 21:190. [PMID: 31429794 PMCID: PMC6701065 DOI: 10.1186/s13075-019-1968-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2018] [Accepted: 07/25/2019] [Indexed: 12/29/2022] Open
Abstract
OBJECTIVE To evaluate the safety and efficacy of intravenous golimumab + methotrexate (MTX) in patients with active rheumatoid arthritis (RA) aged < 65 years and those ≥ 65 years who were enrolled in the GO-FURTHER study. METHODS In the phase III, double-blind, randomized, placebo-controlled GO-FURTHER trial, patients with active RA were randomized to intravenous (IV) golimumab 2 mg/kg + MTX or placebo + MTX at weeks 0 and 4, then every 8 weeks thereafter (with crossover to golimumab at week 16 [early escape] or week 24 [per-protocol]). The final golimumab infusion was at week 100. Assessments included American College of Rheumatology (ACR) 20/50/70 response criteria. Efficacy and adverse events (AEs) were monitored through 2 years. Efficacy and AEs were summarized for patients aged < 65 years or ≥ 65 years; AEs were also summarized for patients < or ≥ 70 years and patients < or ≥ 75 years. RESULTS In GO-FURTHER, 592 patients were randomized to receive placebo (n = 197) or golimumab (n = 395), 515 were aged < 65 years and 77 were ≥ 65 years. At week 24, ACR20 response rates were greater for golimumab + MTX patients compared with placebo + MTX for patients < 65 years (61.6% vs 31.3%, p < 0.001) and those ≥ 65 years (69.5% vs 33.3%; p < 0.01). Infections were the most common AE through week 112 (51.6% in patients < 65 years; 55.3% in patients ≥ 65 years); upper respiratory infections were the most common infection in patients < 65 years (13.2%) and those ≥ 65 years (11.8%). Serious AEs occurred in 17.7% in patients < 65 years and 25.0% of patients ≥ 65 years and included malignancies, pneumonia, fractures, acute pancreatitis, cellulitis, and bacterial arthritis. CONCLUSIONS In GO-FURTHER, ACR response rates were similar between patients < 65 years and patients ≥ 65 years within each treatment group. AEs in elderly patients were similar to the known safety profile of IV golimumab. Immunosenescence is known to increase the risk of infections in the elderly. Elderly patients had a numerically higher incidence of serious infections. Six malignancies occurred in golimumab-treated patients, all in patients < 65 years. TRIAL REGISTRATION clinicaltrials.gov: NCT00973479 . Registered September 9, 2009.

Combined evaluation of biomarkers as predictor of maintained remission in Crohn’s disease. World J Gastroenterol 2019; 25:2354-2364. [PMID: 31148906 PMCID: PMC6529885 DOI: 10.3748/wjg.v25.i19.2354] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Revised: 04/16/2019] [Accepted: 04/20/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The individual performances and the complementarity of Crohn’s disease (CD) activity index (CDAI), C-reactive protein (CRP) and faecal calprotectin (Fcal) to monitor patients with CD remain poorly investigated in the era of “tight control” and “treat to target” strategies.
AIM To assess CDAI, CRP and Fcal variation, alone or combined, after 12 wk (W12) of anti-tumor necrosis factor (TNF) therapy to predict corticosteroids-free remission (CFREM = CDAI < 150, CRP < 2.9 mg/L and Fcal < 250 μg/g with no therapeutic intensification and no surgery) at W52.
METHODS CD adult patients needing anti-TNF therapy with CDAI > 150 and either CRP > 2.9 mg/L or Fcal > 250 μg/g were prospectively enrolled.
RESULTS Among the 40 included patients, 13 patients (32.5%) achieved CFREM at W52. In univariable analysis, CDAI < 150 at W12 (P = 0.012), CRP level < 2.9 mg/L at W12 (P = 0.001) and Fcal improvement at W12 (Fcal < 300 μg/g; or, for patients with initial Fcal < 300 μg/g, at least 50% decrease of Fcal or normalization of Fcal (< 100 μg/g) (P = 0.001) were predictive of CFREM at W52. Combined endpoint (CDAI < 150 and CRP ≤ 2.9 mg/L and FCal improvement) at W12 was the best predictor of CFREM at W52 with positive predictive value = 100.0% (100.0-100.0) and negative predictive value = 87.1% (75.3-98.9). In multivariable analysis, Fcal improvement at W12 [odd ratio (OR) = 45.1 (2.96-687.9); P = 0.03] was a better predictor of CFREM at W52 than CDAI < 150 [OR = 9.3 (0.36-237.1); P = 0.145] and CRP < 2.9 mg/L (0.77-278.0; P = 0.073).
CONCLUSION The combined monitoring of CDAI, CRP and Fcal after anti-TNF induction therapy is able to predict favorable outcome within one year in patients with CD.

Abstract
Although glucocorticoids are the mainstay of treatment in Takayasu arteritis (TA), anti-tumor necrosis factor agents are other treatment options in refractory disease. The onset of TA is generally observed in females of reproductive age. Certolizumab pegol (CZP) lacks a fragment crystallizable region and this gives advantage of minimal transfer through the placenta, which makes CZP a safer option in pregnancy. Although there are case reports and trials about use of infliximab, etanercept, and adalimumab in TA, there are scarce data about use of CZP. In this article, we present three TA cases treated with CZP. While two patients benefited from CZP, one patient was refractory to CZP.

Current clinical issue of skin lesions in patients with inflammatory bowel disease. Clin J Gastroenterol 2019; 12:501-510.

Abstract
Inflammatory bowel disease (IBD) is associated with a number of extraintestinal complications, including skin lesions. Most reports have shown that skin lesions are found in 10-15% of IBD cases, although this depends on the definition of skin lesions. The representative skin lesions in patients with IBD are erythema nodosum, pyoderma gangrenosum, Sweet's syndrome, and so on. These lesions are often associated with IBD progression, and intestinal lesions in particular require appropriate treatment. Recently, another clinical issue regarding skin lesions in patients with IBD, a so-called paradoxical reaction, during the treatment with anti-tumor necrosis factor (TNF)-α agents has emerged. These reactions are termed paradoxical reactions because the skin lesions sometimes resemble psoriasis, although the anti-TNF-α agents have been historically used to treat psoriasis. Paradoxical reactions are reportedly found in approximately 5-10% of patients using anti-TNF-α agents and are no longer rare. Now that the use of biologics is at its culmination, reports regarding paradoxical reactions are predicted to increase in number; thus, we must recognize skin lesions with IBD patients including this type of adverse events and manage them appropriately while consulting with dermatologists.

Abstract
Introduction: Anti-tumor necrosis factor (anti-TNF) treatments are effective in controlling disease activity in many immune-mediated diseases such as psoriasis and ankylosing spondylitis (AS). Although side effects such as infection and skin reactions are predictable in anti-TNF treatment; susceptibility to psoriasis is considered as a paradoxical side effect. Case report: We report a case of forty-year-old male patient with 7 years of AS was taking anti-TNF therapy. He admitted our clinic with widespread guttate sized round, crusty rashes at feet, legs and elbows. In pathological examination of lesions; focal parakeratosis, mild acanthosis, capillary proliferation in the papillary dermis and focal extravasated erythrocytes were observed. He was diagnosed as anti-TNF induced guttate psoriasis. Although there is no definite treatment option, topical treatments, interrupting drug treatment or adding a disease-modifying agent for psoriasis are recommended. In this case report, we aimed to share our clinical approach to the paradoxical psoriasis manifestation which developed after two different anti-TNF treatments in a patient with AS.

Abstract
BACKGROUND Paradoxical development of psoriasis in patients on anti-TNF agents has been increasingly reported. AIM The aim was to characterize the prevalence and clinical characteristics of anti-TNF-associated psoriasis in a large cohort of inflammatory bowel disease patients. METHODS Medical records of patients with Crohn's disease or ulcerative colitis treated with anti-TNF therapy at a single, tertiary IBD center were identified between 2004 and 2016. Patients identified as having developed psoriasis while on anti-TNF underwent detailed retrospective review of dermatologic features and changes in IBD treatment prompted by the development of psoriasis. RESULTS Among 676 patients treated with anti-TNF (infliximab or adalimumab), the incidence of psoriasis was 10.7% (N = 72). Female gender (OR 1.88 [95% CI 1.12-3.17], p = 0.017), stricturing or fistulizing Crohn's disease (OR 1.83 [95% CI 1.04-3.21], p = 0.036) and upper GI Crohn's disease (OR 3.03 [95% CI 1.06-8.33], p = 0.039) were associated with psoriasis development. The median time to psoriasis onset was 569 days from initiation of anti-TNF, with onset occurring earlier in patients who developed psoriasis on adalimumab versus infliximab (457 vs. 790.5 days, p = 0.008). Overall, in 15/72 (20.8%), cases, cessation of the anti-TNF was required as a result of psoriasis. Plaque psoriasis was the most common type of psoriatic lesion (75%). Topical corticosteroids were the most common treatment for psoriasis. CONCLUSION We report a high incidence of anti-TNF-associated psoriasis that was associated with female gender, foregut disease location, and fistulizing and stricturing disease behavior. More prospective studies and genetic analyses evaluating possible pathophysiologic underpinnings of this problem are needed.

Effect of anti-rheumatic treatment on selenium levels in inflammatory arthritis. J Trace Elem Med Biol 2018; 49:91-97.

Abstract
OBJECTIVES The reason for increased cardiovascular risk in inflammatory arthritis (IA) is unclear. Interestingly, selenium-deficiency is suspected to contribute to the development of cardiovascular disease (CVD) in the general population. Although the reference range of serum selenium (s-selenium) is 50-120 μg/L, there are indications that levels up to 85 μg/L might not be sufficient for optimal cardioprotection. Our aim was to examine s-selenium levels in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ankylosing spondylitis (AS), to evaluate the effect of anti-rheumatic treatment on s-selenium levels, and to assess relationships between s-selenium levels and clinical and laboratory parameters including markers of disease activity and CVD risk. METHODS We examined 64 patients with RA, 40 with PsA and 26 with AS starting with methotrexate (MTX) monotherapy or anti-tumor necrosis factor therapy (anti-TNF) with or without methotrexate (anti-TNF ± MTX) due to active disease. S-selenium, inflammatory biomarkers, endothelial function (EF) and other variables were examined at baseline and after 6 weeks and 6 months of treatment. RESULTS In the total IA group, s-selenium increased within 6 weeks of anti-rheumatic treatment, and thereafter the levels remained stable until the end of the 6 months follow-up period. There were no significant differences in s-selenium changes between the three diagnostic groups and between the two treatment regimens. Changes in s-selenium were negatively related to changes in C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), but there were no significant relationships to any other of the examined risk parameters for CVD including EF. CONCLUSION IA patients had s-selenium within the reference range, but below the level that might be necessary for optimal CVD protection. Anti-rheumatic treatment had a relatively rapid and sustained effect on s-selenium levels. The increase in s-selenium was related to reduction in inflammatory activity. In theory, anti-rheumatic drugs might improve s-selenium levels through inhibition of pro-inflammatory processes or through other mechanisms. Although we have not revealed any significant relationships between s-selenium and CVD risk parameters, the role of suboptimal s-selenium levels in pathogenesis of premature CVD in IA cannot be ruled out.

Should we use anti-tumor necrosis factor agents or vedolizumab as first-line biological therapy in ulcerative colitis? Best Pract Res Clin Gastroenterol 2018; 32-33:17-25.

Abstract
Randomized controlled trials with direct comparisons between the different available biological agents in ulcerative colitis are lacking. The comparative efficacy, safety and tolerability, patient profile, patient preference and costs should be taken into account when choosing an appropriate first-line biological. Tumor necrosis factor antagonists have a systemic mode of action, while vedolizumab is mainly gut-selective, and this influences the clinical profile of both treatment options. Tofacitinib will further expand the therapeutic armamentarium in ulcerative colitis. Results of ongoing head-to-head trials between biological agents are likely to change clinical practice in the near future. Biomarkers that predict response to different treatment options in an individual patient are warranted.

Abstract
Because anti-tumor necrosis factor (anti-TNF) therapy has become increasingly popular in many Asian countries, the risk of developing active tuberculosis (TB) among anti-TNF users may raise serious health problems in this region. Thus, the Asian Organization for Crohn's and Colitis and the Asia Pacific Association of Gastroenterology have developed a set of consensus statements about risk assessment, detection and prevention of latent TB infection, and management of active TB infection in patients with inflammatory bowel disease (IBD) receiving anti-TNF treatment. Twenty-three consensus statements were initially drafted and then discussed by the committee members. The quality of evidence and the strength of recommendations were assessed by using the Grading of Recommendations Assessment, Development, and Evaluation methodology. Web-based consensus voting was performed by 211 IBD specialists from 9 Asian countries concerning each statement. A consensus statement was accepted if at least 75% of the participants agreed. Part 1 of the statements comprised 2 parts: risk of TB infection Recommendaduring anti-TNF therapy, and screening for TB infection prior to commencing anti-TNF therapy. These consensus statements will help clinicians optimize patient outcomes by reducing the morbidity and mortality related to TB infections in patients with IBD receiving anti-TNF treatment.

Abstract
INTRODUCTION We incorporated patient feedback from human factors studies (HFS) in the patient-centric design and validation of ava®, an electromechanical device (e-Device) for self-injecting the anti-tumor necrosis factor certolizumab pegol (CZP). METHODS Healthcare professionals, caregivers, healthy volunteers, and patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, or Crohn's disease participated in 11 formative HFS to optimize the e-Device design through intended user feedback; nine studies involved simulated injections. Formative participant questionnaire feedback was collected following e-Device prototype handling. Validation HFS (one EU study and one US study) assessed the safe and effective setup and use of the e-Device using 22 predefined critical tasks. Task outcomes were categorized as "failures" if participants did not succeed within three attempts. RESULTS Two hundred eighty-three participants entered formative (163) and validation (120) HFS; 260 participants performed one or more simulated e-Device self-injections. Design changes following formative HFS included alterations to buttons and the graphical user interface screen. All validation HFS participants completed critical tasks necessary for CZP dose delivery, with minimal critical task failures (12 of 572 critical tasks, 2.1%, in the EU study, and 2 of 5310 critical tasks, less than 0.1%, in the US study). CONCLUSION CZP e-Device development was guided by intended user feedback through HFS, ensuring the final design addressed patients' needs. In both validation studies, participants successfully performed all critical tasks, demonstrating safe and effective e-Device self-injections. FUNDING UCB Pharma.

Abstract
OBJECTIVE Evaluate the safety and efficacy of golimumab through week 120 in Japanese patients with active rheumatoid arthritis (RA) previously treated with DMARDs. METHODS Japanese patients with active RA despite prior DMARDs were randomized to placebo (Group 1, n = 105), golimumab 50 mg (Group 2, n = 101), or golimumab 100 mg (Group 3, n = 102). At week 16, Group 1 patients crossed over to golimumab 50mg; after week 52, a one-time golimumab dose reduction from 100 to 50 mg was permitted. Assessments included ACR20/50/70 responses and good/moderate DAS28-ESR responses. Radiographic progression was assessed with the van der Heijde-modified Sharp (vdH-S) score. Safety and efficacy were assessed through week 120. RESULTS ACR20 response rates at week 52 in Group 1, Group 2, and Group 3 were 70.6%, 71.4%, and 81.9%, respectively, and maintained through week 104 (87.2%, 85.1%, 88.9%, respectively) and week 120 (86.1%, 87.0%, 89.5%, respectively). Similar trends were observed for ACR50, ACR 70, and DAS28-ESR. Median change in total vdH-S at weeks 52, 104, and 120 ranged from 0.0 to 1.5 across treatment groups. Through week 120, 93.8%/97.1% had an AE with golimumab 50 mg/100 mg, respectively, and 19.7%/11.8% had an SAE. Infections were the most common AE. CONCLUSION Clinical response to golimumab 50 mg and 100 mg was maintained over 2 years in Japanese patients with active RA despite prior DMARDs.

Abstract
BACKGROUND Noncompliance in use of anti-tumor necrosis factor (anti-TNF) therapy in patients with moderate-to-severe inflammatory bowel disease (IBD) can be a factor in medication failure. Few studies have evaluated the contribution of depressive symptoms to medication noncompliance in anti-TNF therapies. METHODS A retrospective chart review was performed in a single-center tertiary care IBD center for patients with Crohn's disease and ulcerative colitis starting anti-TNF therapy over a 2-year period. Medication noncompliance was defined as interruption of medication (not filling anti-TNF prescription if injectable or not getting infliximab infusion for 30 days beyond needed date for continuation) due to patient-driven circumstances. Depressive symptoms were evaluated at baseline using the well-validated Patient Health Questionnaire-9 (PHQ-9), with PHQ-9 ≥ 10 indicative of at least moderate depressive symptoms. Statistical analysis was performed using Cox proportional hazards regression controlling for age, sex, psychiatric history, and disease. RESULTS A total of 246 patients (75 with ulcerative colitis, 171 with Crohn's disease) were started on anti-TNF therapy. Seventy-nine patients (32%) had a prior psychiatric diagnosis reported in the medical record. Thirty-three patients (13%) were noncompliant in follow-up. Sixty patients (24%) had at least moderate depressive symptoms at baseline (PHQ ≥ 10). Depressive symptoms at baseline were significantly associated with noncompliance in follow-up (hazards ratio 2.28, CI 1.1-4.6, p < 0.05). CONCLUSION Depressive symptoms at baseline were associated with medication noncompliance of anti-TNF therapies at follow-up when controlling for age, sex, disease type, and history of psychiatric disease.

BACKGROUND Usefulness of thiopurine and scheduled infliximab combination therapy in non-immunomodulator (IM)-naïve Crohn's disease (CD) patients and the optimal length of dual therapy are still debated. AIMS To determine proportion of patients developing disease flare requiring rescue therapy and risk factors associated with disease flare after de-escalation of IM from combination therapy. METHODS Adult CD patients in clinical remission on combination therapy were identified from a large single-center database between 2002 and 2009. Patients who had their IM stopped in the absence of adverse events were included. Association between clinical and demographic variables and time until rescue therapy was analyzed using Cox-proportional hazard models. RESULTS Forty-three CD patients on combination therapy in clinical remission at time of IM de-escalation were identified and followed up for a median duration of 61.6 months (range 5.4-129.5). Median duration of remission on combination therapy prior to IM de-escalation was 12.0 months (range 4-74). Thirty-one patients (72.1%) required rescue therapy during follow-up. On multivariable analysis, age at diagnosis < 16 years versus > 40 years (HR 4.55, 95% CI 1.18-17.62, p = 0.028), using methotrexate instead of azathioprine in combination with infliximab (HR 3.37, 95% CI 1.14, 9.96, p = 0.028), and duration of combination therapy < 6 months (HR 5.68, 95% CI 1.58, 20.36, p = 0.007) increased risk for rescue therapy. CONCLUSIONS A large proportion of CD patients on combination therapy experienced a flare following IM withdrawal. Young age at diagnosis, short duration of combination therapy, and methotrexate use were independent predictors of the need for rescue therapy.

Genetic associations with adverse events from anti-tumor necrosis factor therapy in inflammatory bowel disease patients. World J Gastroenterol 2017; 23:7265-7273. [PMID: 29142473 PMCID: PMC5677193 DOI: 10.3748/wjg.v23.i40.7265] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2017] [Revised: 08/25/2017] [Accepted: 09/13/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To study the type and frequency of adverse events associated with anti-tumor necrosis factor (TNF) therapy and evaluate for any serologic and genetic associations.
METHODS This study was a retrospective review of patients attending the inflammatory bowel disease (IBD) centers at Cedars-Sinai IBD Center from 2005-2016. Adverse events were identified via chart review. IBD serologies were measured by ELISA. DNA samples were genotyped at Cedars-Sinai using Illumina Infinium Immunochipv1 array per manufacturer’s protocol. SNPs underwent methodological review and were evaluated using several SNP statistic parameters to ensure optimal allele-calling. Standard and rigorous QC criteria were applied to the genetic data, which was generated using immunochip. Genetic association was assessed by logistic regression after correcting for population structure.
RESULTS Altogether we identified 1258 IBD subjects exposed to anti-TNF agents in whom Immunochip data were available. 269/1258 patients (21%) were found to have adverse events to an anti-TNF-α agent that required the therapy to be discontinued. 25% of women compared to 17% of men experienced an adverse event. All adverse events resolved after discontinuing the anti-TNF agent. In total: n = 66 (5%) infusion reactions; n = 49 (4%) allergic/serum sickness reactions; n = 19 (1.5%) lupus-like reactions, n = 52 (4%) rash, n = 18 (1.4%) infections. In Crohn’s disease, IgA ASCA (P = 0.04) and IgG-ASCA (P = 0.02) levels were also lower in patients with any adverse events, and anti-I2 level in ulcerative colitis was significantly associated with infusion reactions (P = 0.008). The logistic regression/human annotation and network analyses performed on the Immunochip data implicated the following five signaling pathways: JAK-STAT (Janus Kinase-signal transducer and activator of transcription), measles, IBD, cytokine-cytokine receptor interaction, and toxoplasmosis for any adverse event.
CONCLUSION Our study shows 1 in 5 IBD patients experience an adverse event to anti-TNF therapy with novel serologic, genetic , and pathways associations.

Fatal infections in older patients with inflammatory bowel disease on anti-tumor necrosis factor therapy. Intest Res 2017; 15:524-528. [PMID: 29142521 PMCID: PMC5683984 DOI: 10.5217/ir.2017.15.4.524] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2017] [Revised: 08/16/2017] [Accepted: 08/18/2017] [Indexed: 02/06/2023] Open
Abstract
Anti-tumor necrosis factor (anti-TNF) is highly effective in inflammatory bowel disease (IBD); however, it is associated with an increased risk of infections, particularly in older adults. We reviewed 349 patients with IBD, who were observed over a 12-month period, 74 of whom had received anti-TNF therapy (71 patients were aged <60 years and 3 were aged ≥60 years). All the 3 older patients developed serious infectious complications after receiving anti-TNFs, although all of them were also on concomitant immunosuppressive therapy. One patient developed disseminated tuberculosis, another patient developed cholera diarrhea followed by nosocomial pneumonia, while the third patient developed multiple opportunistic infections (Pneumocystis pneumonia, cryptococcal septicemia and meningitis, Klebsiella septicemia). All 3 patients died within 1 year from the onset of the infection(s). We recommend that anti-TNF, especially when combined with other immunosuppressive therapy, should be used with extreme caution in older adult patients with IBD.

Methotrexate and anti-tumor necrosis factor treatment improves endothelial function in patients with inflammatory arthritis. Arthritis Res Ther 2017; 19:232. [PMID: 29041979 PMCID: PMC5646156 DOI: 10.1186/s13075-017-1439-1] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2017] [Accepted: 09/20/2017] [Indexed: 12/17/2022] Open
Abstract
Background Inflammatory arthritis (IA), including rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA), leads to increased cardiovascular disease occurrence probably due to atherosclerosis. One of the first stages in atherogenesis is endothelial dysfunction (ED). Therefore, we aimed to compare endothelial function (EF) in patients with IA, and to examine the effects of methotrexate (MTX) monotherapy and antitumor necrosis factor (anti-TNF) treatment with or without MTX comedication (anti-TNF ± MTX) on EF. Methods From the PSARA observational study, all patients with RA (n = 64), PsA (n = 29), and AS (n = 20) were evaluated for EF. In patients with ED at baseline (n = 40), we evaluated changes in the Reactive Hyperemic Index (RHI) after 6 weeks and 6 months of antirheumatic therapy. Results In IA patients with ED, RHI significantly improved after 6 weeks (p < 0.001) and 6 months (p < 0.001) of treatment, independent of changes in disease activity parameters. After 6 months, RHI had improved more in the MTX group than in the anti-TNF ± MTX group, and the difference remained statistically significant after adjustments for potential confounders. Among patients with active RA, AS, and PsA, those with AS appeared to have the worst endothelial function, although they were the youngest. Conclusion Treatment with MTX and anti-TNF ± MTX was associated with a relatively fast improvement of EF in IA patients with ED, independent of change in disease activity. Therefore, modes of action other than the anti-inflammatory effect may contribute to the EF improvement. After 6 months, the EF improvement was more pronounced in the MTX group than in the anti-TNF ± MTX group. Trial registration Clinicaltrials, NCT00902005. Registered on 13 May 2009.

Abstract
In patients with Crohn's disease on biologic medications, the use of therapeutic drug monitoring leads to a personalized approach to optimize treatment. Using an algorithmic approach, measurement of drug concentrations and anti-drug antibodies can be used to improve treatment outcomes. Therapeutic drug concentrations and absence of antibodies are associated with improved clinical and endoscopic outcomes. In clinical practice, therapeutic drug monitoring has been shown to be clinically useful and cost-effective in patients experiencing a loss of response to treatment. This review highlights the available data on therapeutic drug monitoring in the treatment of patients with Crohn's disease on biologic medications.

Strategies for overcoming anti-tumor necrosis factor drug antibodies in inflammatory bowel disease: Case series and review of literature. World J Gastrointest Pharmacol Ther 2017; 8:155-161. [PMID: 28828193 PMCID: PMC5547373 DOI: 10.4292/wjgpt.v8.i3.155] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2017] [Revised: 05/14/2017] [Accepted: 06/07/2017] [Indexed: 02/06/2023] Open
Abstract
Anti-tumor necrosis factor (TNF) biologics are currently amongst the most widely used and efficacious therapies for inflammatory bowel disease (IBD). The development of therapeutic drug monitoring for infliximab and adalimumab has allowed for measurement of drug levels and antidrug antibodies. This information can allow for manipulation of drug therapy and prediction of response. It has been shown that therapeutic anti-TNF drug levels are associated with maintenance of remission, and development of antidrug antibodies is predictive of loss of response. Studies suggest that a low level of drug antibodies, however, can at times be overcome by dose escalation of anti-TNF therapy or addition of an immunomodulator. We describe a retrospective case series of twelve IBD patients treated at the University of California-Irvine, who were on infliximab or adalimumab therapy and were found to have detectable but low-level antidrug antibodies. These patients underwent dose escalation of the drug or addition of an immunomodulator, with subsequent follow-up drug levels obtained. Eight of the twelve patients (75%) demonstrated resolution of antidrug antibodies, and were noted to have improvement in disease activity. Though data regarding overcoming low-level anti-TNF drug antibodies remains somewhat limited, cases described in the literature as well as our own experience suggest that this may be a viable strategy for preserving the use of an anti-TNF drug. Low-level anti-TNF drug antibodies may be overcome by dose escalation and/or addition of an immunomodulator, and can allow for clinical improvement in disease status. Therapeutic drug monitoring is an important tool to guide this strategy.

Genetic polymorphisms predict response to anti-tumor necrosis factor treatment in Crohn’s disease. World J Gastroenterol 2017; 23:4958-4967. [PMID: 28785150 PMCID: PMC5526766 DOI: 10.3748/wjg.v23.i27.4958] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2017] [Revised: 04/05/2017] [Accepted: 05/04/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To investigate genetic factors that might help define which Crohn’s disease (CD) patients are likely to benefit from anti-tumor necrosis factor (TNF) therapy.
METHODS This was a prospective cohort study. Patients were recruited from a university digestive disease practice database. We included CD patients who received anti-TNF therapy, had available medical records (with information on treatment duration and efficacy) and who consented to participation. Patients with allergic reactions were excluded. Patients were grouped as ever-responders or non-responders. Genomic DNA was extracted from peripheral blood, and 7 single nucleotide polymorphisms (SNPs) were assessed. The main outcome measure (following exposure to the drug) was response to therapy. The patient genotypes were assessed as the predictors of outcome. Possible confounders and effect modifiers included age, gender, race, and socioeconomic status disease, as well as disease characteristics (such as Montreal criteria).
RESULTS 121 patients were included. Twenty-one were non-responders, and 100 were ever-responders. Fas ligand SNP (rs763110) genotype frequencies, TNF gene -308 SNP (rs1800629) genotype frequencies, and their combination, were significantly different between groups on multivariable analysis controlling for Montreal disease behavior and perianal disease. The odds of a patient with a Fas ligand CC genotype being a non-responder were four-fold higher as compared to a TC or TT genotype (P = 0.009, OR = 4.30, 95%CI: 1.45-12.80). The presence of the A (minor) TNF gene -308 allele correlated with three-fold higher odds of being a non-responder (P = 0.049, OR = 2.88, 95%CI: 1.01-8.22). Patients with the combination of the Fas ligand CC genotype and the TNF -308 A allele had nearly five-fold higher odds of being a non-responder (P = 0.015, OR = 4.76, 95%CI: 1.35-16.77). No difference was seen for the remaining SNPs.
CONCLUSION The Fas-ligand SNP and TNF gene -308 SNP are associated with anti-TNF treatment response in CD and may help select patients likely to benefit from therapy.

Abstract
BACKGROUND Long-term data of certolizumab pegol (CZP) in Crohn's disease (CD) from pivotal registry trials are limited. We therefore aimed to evaluate the long-term efficacy of CZP in clinical practice in Switzerland. METHODS In the First Approved Certolizumab Therapeutic Experience in Switzerland-III phase IV multicenter cohort, patients receiving CZP were prospectively included all over Switzerland in (non-) academic hospitals and private practice. RESULTS We included 104 CD patients (52 male; only 22.1% anti-tumor necrosis factor (TNF) naïve, CZP as third anti-TNF agent in 46.2%) with follow-up time between 6 weeks up to 5 years. During treatment with CZP, we observed a significant decrease of the Harvey Bradshaw Index from a median of 7 at baseline (interquartile range 4-11) to 4, 5, 4, 3, 3, and 2 at weeks 6, 26, 52, 78, 104, and 156, respectively. While anti-TNF naïve patients showed a significantly better response at the end of induction, during CZP maintenance therapy response was similar as compared to anti-TNF experienced patients as well as between patients with a short (0-5 years) vs. long duration of disease (>5 years). CONCLUSIONS CZP is an effective long-term treatment option, including CD patients with long disease duration and prior treatment with 1 or 2 anti-TNF agents.

Abstract
Extraintestinal manifestations are common in inflammatory bowel disease; however, muscular involvement in Crohn disease is rarely reported. We present a case of a 26-year-old male with ileocolonic Crohn disease who developed sudden tenderness in both calves. Doppler ultrasound was negative for deep vein thrombosis. Magnetic resonance imaging of the gastrocnemius muscle showed high intensity signal in the muscle fibers, and muscle biopsy demonstrated nonspecific lymphocytic myositis. Other relevant laboratory results included normal antineutrophil cytoplasmic antibodies and creatine kinase as well as elevated C-reactive protein, erythrocyte sedimentation rate, and anti-Saccharomyces cerevisiae IgG titer. The patient was in clinical remission, being treated with azathioprine 2.5 mg/kg. Prednisone 60 mg/day was initiated with rapid resolution of calf tenderness; however, tenderness soon returned when the dose was tapered to 10 mg/day. Subsequently, prednisone and azathioprine were discontinued, and adalimumab was started at standard induction and maintenance doses. The patient's symptoms resolved shortly after the first induction dose. A repeat magnetic resonance imaging of the calves – 3 months after starting adalimumab – showed complete resolution of muscle inflammation. To our knowledge, this is the first case of gastrocnemius myositis – a rare extraintestinal manifestation of Crohn disease – successfully treated with anti-tumor necrosis factor agents.

Abstract
BACKGROUND AND OBJECTIVE To evaluate the effect of anti-TNF treatments on bone mineral density (BMD), bone remodelling markers (BRM) and receptor activator of nuclear factor κB ligand (RANKL) and osteoprotegerin (OPG) in patients with chronic inflammatory joint diseases. METHODS A longitudinal prospective study was performed under clinical practice conditions on 31 patients diagnosed of rheumatoid arthritis, psoriatic arthropathy and ankylosing spondylitis who had received treatment with anti-TNF alpha drugs for one year. BMD, OPG and RANKL soluble form (sRANKL) were studied at the onset and end of the study. During the study (0, 3, 6, 9 and 12 month), disease activity (SDAI, BASDAI and CRP), functional capacity (HAQ, BASFI), BRM and vitamin D were studied. RESULTS BMD was not modified after one year of treatment. The patients who took corticosteroids had a mean bone mass loss of 3% in the lumbar spine (±1.6, P=.02). In regards to the BRM, did not experience significant changes over the course of the study. Disease activity, both SDAI (P=.002) and BASDAI (P=.002), decreased. OPG was maintained without changes during the year of treatment while both the sRANKL (0.28±0.22, P=.013) and sRANKL/OPG ratio significantly decreased (0.04±0.03, P=.031). CONCLUSION The patients being treated with anti-TNF did not present with a significant loss of DMO during the study (one year), at the same time experiencing an improvement in disease activity. This protection has been clearer in the responding patients.

Abstract
In patients with inflammatory bowel disease (IBD), chronic inflammation is a major risk factor for the development of gastrointestinal malignancies. The pathogenesis of colitis-associated cancer is distinct from sporadic colorectal carcinoma and the critical molecular mechanisms underlying this process have yet to be elucidated. Patients with IBD have also been shown to be at increased risk of developing extra-intestinal malignancies. Medical therapies that diminish the mucosal inflammatory response represent the foundation of treatment in IBD, and recent evidence supports their introduction earlier in the disease course. However, therapies that alter the immune system, often used for long durations, may also promote carcinogenesis. As the population of patients with IBD grows older, with longer duration of chronic inflammation and longer exposure to immunosuppression, there is an increasing risk of cancer development. Many of these patients will require cancer treatment, including chemotherapy, radiation, hormonal therapy, and surgery. Many patients will require further treatment for their IBD. This review seeks to explore the characteristics and risks of cancer in patients with IBD, and to evaluate the limited data on patients with IBD and cancer, including management of IBD after a diagnosis of cancer, the effects of cancer treatment on IBD, and the effect of IBD and medications for IBD on cancer outcomes.
