Treatment of dexamethasone-induced hiccup in chemotherapy patients by methylprednisolone rotation

摘要

Background. Dexamethasone-induced hiccup (DIH) is an underrecognized symptom in patients with cancer, and little information is available about its treatment. The aims of this study were to investigate the feasibility of methylprednisolone rotation as treatment and to confirm the male predominance among those with cancer who experienced DIH during chemotherapy. Methods. Persons with cancer who experienced hiccups during chemotherapy treatment and who were receiving treatment with dexamethasone were presumed to have DIH. The following algorithmic practicewasimplementedfor antiemetic corticosteroid use: rotation from dexamethasone to methylprednisolone in the next cycle and dexamethasone re-administration in the second cycle of chemotherapy after recognition of hiccups to confirm DIH. All other antiemetics except corticosteroid remained unchanged. Patients (n40) were recruited from eight cancercentersinKoreafromSeptember2012toApril2013.Data were collected retrospectively. Results. Hiccup intensity (numeric rating scale [NRS]: 5.38 vs. 0.53) and duration (68.44 minutes vs. 1.79 minutes) were significantly decreased after rotation to methylprednisolone, while intensity of emesis was not increased (NRS: 2.63 vs. 2.08). Median dose of dexamethasone and methylprednisolone were 10 mg and 50 mg, respectively. Thirty-four (85%) of 40 patientsshowed complete resolution of hiccups after methylprednisolone rotation in the next cycle. Of these 34 patients, 25 (73.5%) had recurrence of hiccups after dexamethasone re-administration. Compared with baseline values, hiccup intensity (NRS: 5.24 vs. 2.44)andduration(66.43minutesvs.22.00minutes)weresignificantly attenuated after dexamethasone re-administration. Of the 40 eligible patients, 38 (95%) were male. Conclusion. DIH during chemotherapy could be controlled without losing antiemetic potential by replacing dexamethasone with methylprednisolone.Wealso identified a male predominanceof DIH. Further prospective studies are warranted.
