Síndrome de hiperémesis por cannabis: incidencia y tratamiento con capsaicina tópica / Cannabis hyperemesis syndrome: Incidence and treatment with topical capsaicin

Introducción: Existen pocos estudios en España acerca del síndrome de hiperémesis cannabinoide (SHC), así como sobre el uso de capsaicina tópica para su tratamiento.Métodos:Estudio retrospectivo de pacientes mayores de 14 años atendidos en un servicio de urgencias hospitalario durante 2018 y 2019 con diagnóstico de SHC con base en los siguientes criterios: cuadro clínico compatible, consumo de cannabis menor de 48h y test de cannabis en orina positivo. Se recogieron variables epidemiológicas, clínicas, tiempos asistenciales y tratamiento (incluyendo el uso de capsaicina tópica al 0,075%).Resultados:Se estudiaron 59 asistencias de 29 pacientes (4,4 casos/10.000 visitas, IC 95% 2,8-4,7). Un 50% volvieron a urgencias por SHC, diferenciándose estos solo en más consumo de tabaco (p=0,01) y cocaína (p=0,031). En un 74,6% de las visitas se utilizó capsaicina. El tiempo medio de resolución de los vómitos tras su aplicación fue de 17,87min.Conclusiones:Aunque probablemente esté infradiagnosticado, el SHC presenta una incidencia baja en las urgencias en España, y con alta reincidencia de los pacientes. El uso de pomada de capsaicina es eficiente y seguro. (AU)

There are few studies in Spain on cannabinoid hyperemesis syndrome (CHS), as well as on the use of topical capsaicin as a treatment.Methods:Retrospective study of patients over 14 years of age seen in a hospital emergency department during 2018 and 2019 with a diagnosis of CHS based on the following criteria: compatible clinical picture, cannabis use less than 48h and positive urine cannabis test. Epidemiological and clinical variables, attendance times and treatment (including use of topical capsaicin 0.075%) were collected.Results:Fifty-nine attendances were studied, from 29 patients (4.4 cases/10,000 visits, 95% CI 2.8-4.7). Fifty per cent returned for CHS, differing only in more tobacco (P=.01) and cocaine (P=.031) use. Capsaicin was used in 74.6% of visits. The mean time to resolution of vomiting after application was 17.87min.Conclusions:Although probably underdiagnosed, CHS has a low incidence in the emergency department in Spain, with high patient recurrence. The use of capsaicin ointment is efficient and safe. (AU)

El síndrome de hiperemesis cannabinoide (SHC)es todavía bastante desconocido entre los clínicos españoles de cualquier especialidad, comoel trabajo de Ochoa-Mangado y Madoz-Gúrpide(2021) pone de manifiesto y al que nos gustaría aportarotros aspectos a tener en cuenta. (AU)

Cannabinoid hyperemesis syndrome (CHS) is stillrelatively unknown among Spanish clinicians ofany specialty, a situation highlighted in studiessuch as that by Ochoa-Mangado and MadozGúrpide (2021), and to which we would like to contributeother aspects for consideration. (AU)
