Association between the incidence of infusion-related reactions by obinutuzumab and the dose of corticosteroid as premedication: a multicenter retrospective cohort study
Abstract
BACKGROUND: Premedication with corticosteroids is recommended for prophylaxis against infusion-related reactions (IRRs) caused by obinutuzumab despite a lack of solid evidence regarding the dose of corticosteroids. METHODS: The incidence rates of IRR in the high-dose and low-dose corticosteroid groups were investigated and compared using Student’s t-test.Univariable and multivariable logistic regression analyses were performed on patients to explore the risk of developing IRRs with obinutuzumab. RESULTS: The incidence of IRRs in the high-dose and low-dose corticosteroid groups at the initial administration of obinutuzumab was 27.0% (41/152) and 48.4% (31/64), respectively, indicating that the high-dose group had a lower incidence of IRRs (p = 0.002). The incidence of IRRs at the initial administration of obinutuzumab was significantly associated with the administration of first-generation histamine 1 receptor antagonist (OR = 3.31, 95% CI: 1.16–9.47; reference: second-generation histamine 1 receptor antagonist), hydrocortisone (OR = 7.21, 95% CI: 1.57–33.15; reference: dexamethasone), and methylprednisolone (OR = 3.99, 95% CI :1.13–14.10; reference: dexamethasone), although no association was found with the lower dose of corticosteroids. CONCLUSIONS: Although no association was found between corticosteroid dosage and IRR when considering multiple factors, dexamethasone may be a better option than hydrocortisone or methylprednisolone for preventing IRR.

How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
