Infliximab outperformed golimumab for moderate-to-severe ulcerative colitis. S Singh et al. Clin Gastroenterol Hepatol 2020; 18: 424-31. Using data from three phase 3 trials (1793 patients), the authors found that infliximab worked more rapidly and with greater efficacy than golimumab. At week 6, patient reported outcome of clinical remission was 50.0% and 38.9% (aOR 2.0). After adjusting for patient variables, infliximab was superior in achieving clinical remission with aOR 3.01 (39% vs. 21%).
Increasing incidence of inflammatory bowel disease in Latin America and Caribbean. PG Kotze et al. Clin Gastroenterol Hepatol 2020; 18: 304-12. This systematic review examined incidence & prevalence of IBD over the last 30 years. In Brazil, for example, the incidence of Crohn’s disease jumped from 0.08 per 100,000 person-years in 1988 to 5.5 per 100,000 person-years in 2015.

Adverse Effects of Low-Dose Methotrexate (≤20 mg/week). DH Solomon et al. Ann Intern Med. 2020. DOI: 10.7326/M19-3369. n=4786, median age 66 years. This was a secondary analyses of a double-blind, placebo-controlled, randomized trial. “With the exception of increased risk for skin cancer (HR, 2.05 [CI, 1.28 to 3.28]), the treatment groups did not differ in risk for other cancer or mucocutaneous, neuropsychiatric, or musculoskeletal AEs.” There were increased risks of gastrointestinal, infectious, pulmonary, and hematologic AE.
