Antiemetic Corticosteroid Rotation from Dexamethasone to Methylprednisolone to Prevent Dexamethasone Induced Hiccup in Cancer Patients Treated with Chemotherapy : A Randomized, Single Blind, Crossover Phase III Trial
Menée en Corée auprès de 65 patients atteints d'un cancer traité par chimiothérapie, cet essai de phase III évalue la possibilité de remplacer la dexaméthasone par la méthylprednisolone au cours d'un traitement antiémétique pour réduire l'intensité d'une myoclonie phrénoglottique (hoquet) liée à la dexaméthasone sans affecter l'efficacité du traitement
Background : To assess whether the rotation of dexamethasone to methylprednisolone decreases the intensity of dexamethasone induced hiccup (DIH) in cancer patients treated with chemotherapy. Materials and Methods : Adult patients who experienced DIH within 3 days after the administration of dexamethasone as an antiemetic were screened. Eligible patients were randomly assigned to receive dexamethasone (n = 33) or methylprednisolone (n = 32) as an antiemetic (randomization phase). In the next cycle of chemotherapy, the dexamethasone group received methylprednisolone and vice versa in the methylprednisolone group (crossover phase). The primary endpoint was the difference in hiccup intensity as measured using the numeric rating scale (NRS) between two groups. Results : No female patients were enrolled, although the study did not exclude them. At the randomization phase, hiccup frequency was 28/33 (84.8%) in the dexamethasone group versus 20/32 (62.5%) in the methylprednisolone group (p = .04). Intensity of hiccup was significantly higher in the dexamethasone group than that in the methylprednisolone group (mean NRS, 3.5 vs. 1.4, p < .001). At the crossover phase, hiccup intensity was further decreased after the rotation of dexamethasone to methylprednisolone in the dexamethasone group (mean NRS, 3.5 to 0.9, p < .001), while it was increased by rotating methylprednisolone to dexamethasone in the methylprednisolone group (mean NRS, 1.4 to 3.3, p = .025). There were no differences in emesis intensity between the two groups at either the randomization or crossover phases. Clinicaltrials.gov identifier: NCT01974024. Conclusion : Dexamethasone induced hiccup is a male predominant phenomenon that can be ameliorated by rotating dexamethasone to methylprednisolone without compromising the antiemetic efficacy. Implications for Practice : In this randomized, multicenter, phase III trial, hiccup intensity was significantly lower when the antiemetic corticosteroid was rotated from dexamethasone to methylprednisolone without a change in emesis intensity than that when dexamethasone was maintained. At the crossover phase, hiccup intensity was increased again if dexamethasone was readministered instead of methylprednisolone. The present study demonstrated that dexamethasone induced hiccup can be improved by rotating from dexamethasone to methylprednisolone without compromising its antiemetic efficacy.
