Abstract

BACKGROUND: Patients with mast cell diseases may suffer from various distressing symptoms, which can be insufficiently controlled with available therapies, severely affecting their quality of life. There is a need for new and safe treatment options for these patients. OBJECTIVES: We aimed to evaluate safety and efficacy of omalizumab administration in patients with a symptomatic mast cell disorder. METHODS: We included 55 patients with a mast cell disorder associated with debilitating symptoms who received omalizumab treatment between January 2015 and December 2017, after a multidisciplinary team meeting at the French National Reference Center for Mastocytosis. RESULTS: A complete response was achieved for 1 patient (1.8%), a major response for 30 patients (54.5%), and a partial response for 12 patients (21.8%), resulting in an overall best response rate of 78.2% (43 of 55 patients). The response was persistent at least 3 months in 33 of 43 responding patients (76.7%). At the last follow-up, the final overall response rate was 58.2% (32 of 55 patients). Median time to first response was 2 months and median time to best response was 6 months. Omalizumab was dramatically effective on all superficial and general vasomotor symptoms and on most gastrointestinal or urinary symptoms, and partially effective on most neuropsychiatric symptoms. Safety profile was acceptable, except for one severe adverse event (edema of the larynx and dyspnea after the first injection of omalizumab). Side effects were reported in 16 patients (29%), mainly of low to mild intensity, yet causing interruption of treatment in 5 patients (9%). CONCLUSION: Omalizumab seems to be a useful therapeutic option to control mast cell-mediator symptoms and displays a favorable safety profile.

  • Response to additional drugs, including multitargeted tyrosine kinase inhibitors (in patients with SM, such as midostaurin) and anti-IgE therapy (omalizumab), may be considered an indirect sign of MCA or MCAS.

    The Results (page not provided) report symptom improvement with omalizumab in patients already diagnosed with mast-cell disorders, including MCAS. The Patients section describes diagnostic response to histamine blockers or cromolyn, not omalizumab; the paper does not say that response to omalizumab or midostaurin is an indirect sign of MCA or MCAS.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
