Item Comparative Effectiveness of Anti-TNF in Combination With Low-Dose Methotrexate vs Anti-TNF Monotherapy in Pediatric Crohn's Disease: A Pragmatic Randomized Trial(Elsevier, 2023-07) Kappelman, Michael D.; Wohl, David A.; Herfarth, Hans H.; Firestine, Ann M.; Adler, Jeremy; Ammoury, Rana F.; Aronow, Jeanine E.; Bass, Dorsey M.; Bass, Julie A.; Benkov, Keith; Berenblum Tobi, Catalina; Boccieri, Margie E.; Boyle, Brendan M.; Brinkman, William B.; Cabera, Jose M.; Chun, Kelly; Colletti, Richard B.; Dodds, Cassandra M.; Dorsey, Jill M.; Ebach, Dawn R.; Entrena, Edurne; Forrest, Christopher B.; Galanko, Joseph A.; Grunow, John E.; Gulati, Ajay S.; Ivanova, Anastasia; Jester, Traci W.; Kaplan, Jess L.; Kugathasan, Subra; Kusek, Mark E.; Leibowitz, Ian H.; Linville, Tiffany M.; Lipstein, Ellen A.; Margolis, Peter A.; Minar, Phillip; Molle-Rios, Zarela; Moses, Jonathan; Olano, Kelly K.; Osaba, Lourdes; Palomo, Pablo J.; Pappa, Helen; Park, K. T.; Pashankar, Dinesh S.; Pitch, Lisa; Robinson, Michelle; Samson, Charles M.; Sandberg, Kelly C.; Schuchard, Julia R.; Seid, Michael; Shelly, Kimberly A.; Steiner, Steven J.; Strople, Jennifer A.; Sullivan, Jillian S.; Tung, Jeanne; Wali, Prateek; Zikry, Michael; Weinberger, Morris; Saeed, Shehzad A.; Bousvaros, Athos; Medicine, School of MedicineBackground & Aims Tumor necrosis factor inhibitors, including infliximab and adalimumab, are a mainstay of pediatric Crohn’s disease therapy; however, nonresponse and loss of response are common. As combination therapy with methotrexate may improve response, we performed a multicenter, randomized, double-blind, placebo-controlled pragmatic trial to compare tumor necrosis factor inhibitors with oral methotrexate to tumor necrosis factor inhibitor monotherapy. Methods Patients with pediatric Crohn’s disease initiating infliximab or adalimumab were randomized in 1:1 allocation to methotrexate or placebo and followed for 12–36 months. The primary outcome was a composite indicator of treatment failure. Secondary outcomes included anti-drug antibodies and patient-reported outcomes of pain interference and fatigue. Adverse events (AEs) and serious AEs (SAEs) were collected. Results Of 297 participants (mean age, 13.9 years, 35% were female), 156 were assigned to methotrexate (110 infliximab initiators and 46 adalimumab initiators) and 141 to placebo (102 infliximab initiators and 39 adalimumab initiators). In the overall population, time to treatment failure did not differ by study arm (hazard ratio, 0.69; 95% CI, 0.45–1.05). Among infliximab initiators, there were no differences between combination and monotherapy (hazard ratio, 0.93; 95% CI, 0.55–1.56). Among adalimumab initiators, combination therapy was associated with longer time to treatment failure (hazard ratio, 0.40; 95% CI, 0.19–0.81). A trend toward lower anti-drug antibody development in the combination therapy arm was not significant (infliximab: odds ratio, 0.72; 95% CI, 0.49–1.07; adalimumab: odds ratio, 0.71; 95% CI, 0.24–2.07). No differences in patient-reported outcomes were observed. Combination therapy resulted in more AEs but fewer SAEs. Conclusions Among adalimumab but not infliximab initiators, patients with pediatric Crohn’s disease treated with methotrexate combination therapy experienced a 2-fold reduction in treatment failure with a tolerable safety profile.

Joseph; Dotson, Jennifer L.; Assi, Maha A.; Antoun, Smyrna A.; Hamoud, Kassem A.; Burdette, Steven D.; Freifeld, Alison G.; McKinsey, David; Money, Mary E.; Myint, Thein; Andes, David R.; Hoey, Cynthia A.; Kaul, Daniel A.; Dickter, Jana K.; Liebers, David E.; Miller, Rachel A.; Muth, William E.; Prakash, Vidhya; Steiner, Frederick T.; Walker, Randall C.; Hage, Chadi A.; Department of Medicine, IU School of MedicineBACKGROUND: Histoplasmosis may complicate tumor necrosis factor (TNF)-α blocker therapy. Published case series provide limited guidance on disease management. We sought to determine the need for long-term antifungal therapy and the safety of resuming TNF-α blocker therapy after successful treatment of histoplasmosis. METHODS: We conducted a multicenter retrospective review of 98 patients diagnosed with histoplasmosis between January 2000 and June 2011. Multivariate logistic regression was used to evaluate risk factors for severe disease. RESULTS: The most commonly used biologic agent was infliximab (67.3%). Concomitant corticosteroid use (odds ratio [OR], 3.94 [95% confidence interval {CI}, 1.06-14.60]) and higher urine Histoplasma antigen levels (OR, 1.14 [95% CI, 1.03-1.25]) were found to be independent predictors of severe disease. Forty-six (47.4%) patients were initially treated with an amphotericin B formulation for a median duration of 2 weeks. Azole treatment was given for a median of 12 months. TNF-α blocker therapy was initially discontinued in 95 of 98 (96.9%) patients and later resumed in 25 of 74 (33.8%) patients at a median of 12 months (range, 1-69 months). The recurrence rate was 3.2% at a median follow-up period of 32 months. Of the 3 patients with recurrence, 2 had restarted TNF-α blocker therapy, 1 of whom died. Mortality rate was 3.2%. CONCLUSIONS: In this study, disease outcomes were generally favorable. Discontinuation of antifungal treatment after clinical response and an appropriate duration of therapy, probably at least 12 months, appears safe if pharmacologic immunosuppression has been held. Resumption of TNF-α blocker therapy also appears safe, assuming that the initial antifungal therapy was administered for 12 months.
