ABSTRACT

OBJETIVO: O objetivo deste estudo foi determinar se a administração de ciproheptadina é capaz de induzir ganho de peso em pacientes com fibrose cística. MÉTODOS: Foi realizado um estudo duplo-cego, controlado com placebo em dois centros no Brasil. Vinte e cinco pacientes com fibrose cística entre 5 e 18 anos completaram o estudo. Os pacientes foram randomizados em dois grupos, para receber ciproheptadina 4 mg três vezes por dia durante 12 semanas ou placebo. Todos os dados foram coletados no início e no final do período de estudo e incluíram peso, altura e espirometria. RESULTADOS: O ganho de peso médio foi de 0,67 kg e 1,61 kg nos grupos placebo e ciproheptadina, respectivamente (p = 0,036). O índice de massa corporal (IMC) diminuiu 0,07 kg/m² no grupo placebo e aumentou 0,46 kg/m² no grupo intervenção (p = 0,027). A mudança no IMC para a idade (escore z) foi de -0,19 no grupo placebo e 0,20 no grupo ciproheptadina (p = 0,003). O IMC escore z diminuiu 0,19 no grupo placebo e aumentou 0,2 no grupo ciproheptadina (p = 0,003). Alterações na função pulmonar não foram estatisticamente diferentes. CONCLUSÃO: O uso de ciproheptadina em pacientes com fibrose cística foi bem tolerado, apresentando um ganho de peso significativo e um aumento no IMC após 12 semanas. Foi encontrado um tamanho de efeito clinicamente relevante para o peso/idade (escore z) e IMC para idade (escore z). Tais achados sugerem que a prescrição de ciproheptadina pode ser uma abordagem alternativa para pacientes que precisam de suporte nutricional por um curto período de tempo.


OBJECTIVE: To determine whether the administration of cyproheptadine was able to induce weight gain in patients with cystic fibrosis. METHODS: We performed a double-blind, placebo-controlled trial in two centers in Brazil. Twenty-five patients with cystic fibrosis between 5 and 18 years completed the study. Patients were randomized into two groups, to receive either cyproheptadine 4 mg three times per day for 12 weeks or placebo. All data were collected at the beginning and at the end of the study period and included weight, height and spirometry. RESULTS: Average weight gain was 0.67 kg in the placebo group and 1.61 kg in the cyproheptadine group (p = 0.036). Body mass index (BMI) decreased 0.07 kg/m² in the placebo group and increased 0.46 kg/m² in the intervention group (p = 0,027). The change in BMI for age (z score) was -0.19 in the placebo group and +0.20 in the cyproheptadine group (p = 0.003). BMI z score decreased 0.19 in the placebo group and increased 0.2 in the cyproheptadine group (p = 0.003). Changes in pulmonary function were not statistically different. CONCLUSION: Use of cyproheptadine in cystic fibrosis patients was well tolerated, showing a significant weight gain and a significant increase in BMI after 12 weeks. A clinically relevant effect size for weight/age (z score) and body mass index for age (z score) was found. Such findings suggest that the prescription of cyproheptadine can be an alternative approach for patients who need nutritional support for a short period of time.

ABSTRACT

El síndrome serotoninérgico (SS) se caracteriza por la presencia de disfunción autonómica, deterioro neuromuscular y alteraciones en el estado mental. El diagnóstico es clínico y por laboratorio. El tratamiento es mediante medidas de apoyo a base de líquidos, hipotermia, benzodiacepinas y, cuando lo amerite, intubación y ventilación mecánica. El pilar de la intervención farmacológica es ciproheptadina, un antagonista central H1, con un antagonismo periférico 5-HT2A. El medicamento disponible sólo se puede administrar por vía oral, por lo que en enfermos críticos debe administrarse a través de sonda nasoyeyunal. El objetivo de este trabajo es presentar un caso de SS y revisar la literatura al respecto.


The serotonin syndrome (SS) is characterized by a spectrum of signs characterized by autonomic dysfunction, neuromuscular impairment, and alterations in mental status. The diagnosis of the serotonin syndrome is clinical and by laboratory evaluation. Treatment is with active cooling and benzodiazepines to control agitation, and intubation, especially in patients with severe hyperthermia and delirium. The mainstay of pharmacologic intervention is cyproheptadine, a centrally acting H1-antagonist, with a prominent peripheral 5-HT2A antagonism. The drug is only available orally, and if the patient is unable to swallow, the drug should be administered nasogastrically. The objective of this paper is report a case of Serotonin Syndrome and review the literature related to this disease.

ABSTRACT

El síndrome serotonínico es un cuadro neurológico agudo debido a hiperactividad serotoninérgica, por la interacción de drogas que refuerzan o mimetizan la acción del neurotrasmisor. La incidencia del síndrome de serotonina es ascendente por la disponibilidad creciente de fármacos serotoninérgicos como los antidepresivos. Por ello es importante que los médicos reconozcan y manejen adecuadamente el síndrome serotonínico. Este reporte de caso se refiere a una intoxicación accidental por el neuroléptico atípico olanzapina en un niño de 2 años, quien desarrolló manifestaciones clínicas como agitación, sudoración, mioclonías, clonus espontáneo e hipertermia, considerados como criterios diagnóstico del cuadro. La terapia consistió en descontaminación interna con lavado gástrico, carbón activado y sulfato de sodio, ciproheptadina, propranolol y furosemida. Su evolución fue satisfactoria. En nuestro país hay disponibilidad de la mayoría de los fármacos causales y tienen amplio uso, por lo que es probable el subregistro del síndrome. De allí la importancia de este reporte de caso


Serotonin syndrome is an acute neurologic picture due to serotonergic hyperactivity, due to the interaction of drugs that enhance or mimic the action of the serotonin. The incidence of serotonin syndrome is rising because of the growing availability of serotonergic drugs such as antidepressants. It is therefore important that clinicians recognize and manage appropriately this syndrome. This case report refers to an accidental poisoning by the atypical neuroleptic olanzapine in a 2 year old boy who developed clinical manifestations such as agitation, sweating, myoclonus, spontaneous clonus and hyperthermia, considered as diagnostic criteria for the syndrome. Therapy consisted of internal decontamination with gastric lavage, activated charcoal and sodium sulfate, cyproheptadine, propranolol and furosemide. The clinical outcome was satisfactory. In our country the majority of the causal drugs are easily available and widely employed, for which reason it is probable that this syndrome is under registered. Hence the importance of this case report
