Item 356: Phase-II Study of Infliximab for the Prophylaxis of Acute Graft-Versus-Host Disease (GVHD) Following Allogeneic Hematopoietic Stem Cell Transplantation (AHSCT)(American Society for Blood and Marrow Transplantation, 2008-02-01) Hamadani, M.; Phillips, G.; Elder, P.; Jansak, B.; Blum, W.; Penza, S.; Lin, T.S.; Farag, S.S.; Devine, S.M.; Medicine, School of MedicineItem 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.

Despite their many benefits, several serious side effects exist and adverse reactions do occur from these medications. While many of the medications' potential adverse effects were anticipated and recognized in clinical trials prior to drug approval, several more rare adverse reactions were recorded in the literature as the popularity, availability and distribution of these medications grew. Of these potential adverse reactions, liver injury, although uncommon, has been observed in some patients. As case reports accrued over time and ultimately case series developed, the link became better established between this family of medicines and various patterns of liver injury. Interestingly, it appears that the majority of cases exhibit an autoimmune hepatitis profile both in serological markers of autoimmune liver disease and in classic autoimmune features seen on hepatic histopathology. Despite the growing evidence of this relationship, the pathogenesis of this reaction remains incompletely understood, but it appears to depend on characteristics of the medications and the genetic composition of the patients; it is likely more complicated than a simple medication class effect. Because of this still incomplete understanding and the infrequency of the occurrence, treatments have also been limited, although it is clear that most patients improve with cessation of the offending agent and, in certain cases, glucocorticoid use. However, more needs to be done in the future to unveil the underlying mechanisms of this adverse reaction.Item Histoplasmosis complicating tumor necrosis factor-α blocker therapy: a retrospective analysis of 98 cases(Oxford University Press, 2015-08-01) Vergidis, Paschalis; Avery, Robin K.; Wheat, L. 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.Item Inflammatory bowel disease in Hermansky–Pudlak syndrome: a retrospective single-centre cohort study(Wiley, 2021) O’Brien, K. J.; Parisi, X.; Shelman, N. R.; Merideth, M. A.; Introne, W. J.; Heller, T.; Gahl, W. A.; Malicdan, M. C. V.; Gochuico, B. R.; Pathology and Laboratory Medicine, School of MedicineBackground: Knowledge about inflammatory bowel disease (IBD) in patients with Hermansky-Pudlak syndrome (HPS), a rare autosomal recessive disorder characterized by defective biogenesis of lysosome-related organelles, could provide insights into IBD in general. Objective: To expand the understanding of IBD in patients with HPS. Methods: Retrospective review of records from patients with HPS evaluated at the National Institutes of Health Clinical Center from 1995 to 2019 was conducted. Clinical features of IBD, genotyping results and histologic findings of colectomy specimens were analysed. Results: IBD affected 37 (14.2%; 12 male, 25 female) of 261 patients with HPS. Median age of onset was 17 years; range was 1 to 52 years. The most common symptoms of HPS IBD were hematochezia, abdominal pain and loose stools. Fistulae or extra-intestinal manifestations developed in 30% or 22%, respectively. Genotyping showed that patients with biallelic variants in HPS1, HPS3, HPS4 or HPS6 were diagnosed with IBD. Six children had very early-onset IBD. Patients with HPS-3 had mild manifestations of IBD. Medical therapy and bowel resection were utilized to treat 73% and 35% of patients with HPS IBD, respectively; 7 of 13 patients receiving anti-tumor necrosis factor alpha therapy had prolonged clinical responses. Active cryptitis, chronic inflammatory changes, granulomas and ceroid lipofuscinosis were histopathologic findings in three colectomy specimens. Conclusions: IBD resembling Crohn's disease affects some patients with HPS; genetic heterogeneity is a feature of HPS IBD. HPS3 is a new gene associated with human IBD. Very early-onset IBD can develop in HPS.Item Recurrent pneumonia and colobronchial fistula from Crohn’s disease: Infliximab alters and simplifies surgical management(Hellenic Society of Gastroenterology, 2012) Mercadal, Nuria Rosa; Wiebke, Eric A.; Surgery, School of MedicineWe report a rare case of right-sided colobronchial fistula in a 47-year-old, severely malnourished male with a history of regional enteritis and recurrent right lower and middle lobe pneumonias medically managed with the addition of the immunomodulator infliximab prior to surgery. On admission, evaluation of sputum cultures and chest radiograph pattern of pneumonia led to the suspicion of colobronchial fistula. This diagnosis was confirmed by abdominal CT enteroclysis. This patient's pneumonia was initially treated with empiric antibiotics, then focused antibiotics based on culture results. The treatment for the regional enteritis and the secondary colobronchial fistula consisted of immunosuppression with infliximab, bowel rest, and total parenteral nutrition. The patient was discharged on a limited course of prednisone and received maintenance therapy with 3mg/kg IV infliximab infusions for four additional treatments with dramatic improvement in his clinical condition. Surgical therapy consisted of only bowel resection; no thoracic surgery or lung resection was necessary. The patient has had a dramatic improvement in his clinical condition and is currently disease-free on no maintenance therapy. The use of TNF-blocking agents such as infliximab may simplify the surgical approach in patients with complicated fistulous Crohn's disease.Item Sclerosing Mesenteritis Complicated With Mesenteric Lymphoma Responsive to Ustekinumab(Wolters Kluwer, 2022-05-25) Byriel, Ben; Walker, Megan; Fischer, Monika; Medicine, School of MedicineA 45-year-old man with a 10-year history of biopsy-proven, steroid-dependent sclerosing mesenteritis failed/was intolerant to tamoxifen, azathioprine, colchicine, cyclophosphamide, and methotrexate. He developed osteoporosis, diabetes, and bilateral cataracts. He responded to infliximab but was diagnosed with mesenteric large B-cell lymphoma 6 months after treatment initiation. He achieved remission from lymphoma after chemotherapy, but the sclerosing mesenteritis remained poorly controlled. He was treated with ustekinumab (520 mg intravenously followed by 90 mg subcutaneously every 8 weeks), leading to complete steroid-free remission. He remains symptom and cancer-free 24 months after starting ustekinumab.
