SA Draiweesh et al. Safety of Combination Biologic and Antirejection Therapy Post-Liver Transplantation in Patients with Inflammatory Bowel Disease. Inflamm Bowel Dis 2020; 26: 949-59. In this case series of 19 patients, 14 who had liver transplantation for PSC, there was no increased risk of serious infections among patients receiving biologic therapy in combination with antirejection medications.
A Malian et al. Pedictors [sic] of Perianal Fistula Relapse in Crohn’s Disease. Inflamm Bowel Dis 2020; 26: 926-31. In this retrospective study with 137 patients, fistula relapse rates were not different in patients receiving infliximab or adalimumab (P = 0.66). In patients treated by anti-TNF at inclusion, discontinuation of anti-TNF therapy (odds ratio 3.49, P = 0.04), colonic location (OR 6.25, P = 0.01), and stricturing phenotype (odds ratio 4.39, P = 0.01) were independently associated with fistula relapse in multivariate analysis.
M-H Wang et al. Unique Phenotypic Characteristics and Clinical Course in Patients With Ulcerative Colitis and Primary Sclerosing Cholangitis: A Multicenter US Experience. Inflamm Bowel Dis 2020; 26: 774-81. Among 522 patients with UC, 56 (10.7%) had PSC. Compared with UC alone, patients with UC-PSC were younger (younger than 20 years) at diagnosis (odds ratios [OR], 2.35; adjusted P = 0.02) and had milder UC severity (adjusted P = 0.05), despite having pancolonic involvement (OR, 7.01; adjusted P < 0.001). In the biologics era (calendar year 2005 to 2015), patients with UC-PSC less commonly received anti-TNF therapy compared with patients with UC (OR, 0.38; adjusted P = 0.009), but their response rates were similar.
B Barberio et al. Matrix Metalloproteinase 3 Predicts Therapeutic Response in Inflammatory Bowel Disease Patients Treated with Infliximab. Inflamm Bowel Dis 2020; 26: 756-62. Retrospectively, 73 IBD patients who had received IFX for at least 1 year were enrolled: 35 patients were responders and 38 were nonresponders at 52 weeks…The MMP3 levels were similar at baseline (19.83 vs 17.92 ng/mL), but at postinduction, patients who failed to respond at 1 year had significantly higher levels than patients who responded (26.09 vs 8.68 ng/mL, P < 0.001); the difference was confirmed at week 52 (29.56 vs 11.48 ng/mL, P < 0.001)…The MMP3 serum determination may represent an early marker of response to infliximab.
