Resumen


Resumen

Introducción: la clozapina (CZP) es un antipsicótico efectivo en la psicosis que no responde a otros antipsicóticos, pero tiene efectos metabólicos adversos y se relaciona con la generación de crisis epilépticas (CE). Existe poca información sobre su efecto en variables metabólicas y sobre las CE en pacientes con epilepsia.

Objetivo: describir el efecto de la CZP en el perfil metabólico, el perfil hematológico y la frecuencia de CE en pacientes con epilepsia y con psicosis o agresividad.

Método: serie de casos de pacientes con epilepsia y psicosis o agresividad que recibieron CZP con un seguimiento de 18 semanas. Se revisaron los expedientes clínicos de 2008-2018. Se incluyeron 30 pacientes con epilepsia que recibieron CZP. Se hizo una comparación pareada (prueba t de Student o de signo y rango de Wilcoxon), antes y después del inicio de la CZP, de las variables metabólicas (glucosa, colesterol y triglicéridos) y hematológicas, el peso, el índice de masa corporal (IMC) y las CE mensuales.

Resultados: la edad media al iniciar la CZP fue de 31.9 ± 16.07 años. La dosis media fue 193 mg/día. Hubo incremento en el IMC (p = 0.001; aumento de 3.2 kg/m2; mediana = 3.08), los triglicéridos (p = 0.002) y la glucosa (p = 0.030). La ganancia de peso fue de 7 ± 10.4 kg (p = 0.292; mediana = 4 kg). El promedio de CE mensuales se redujo de 4.9 (mediana = 2) a 2.04 (p = 0.001; mediana = 1).

Conclusiones: este estudio aporta información del perfil de seguridad del uso de CZP en pacientes con epilepsia y psicosis o agresividad. Se observó una disminución en la frecuencia mensual de CE, así como aumentos moderados de los triglicéridos, la glucosa y el IMC, que coinciden con lo descrito por otros autores.

Abstract

Background: Clozapine (CZP) is an antipsychotic used in resistant psychosis, but has adverse metabolic effects and is associated with new onset or worsening of epileptic seizures (ES). There is not enough information available regarding its effect on metabolic variables and on ES in patients with epilepsy.

Objective: To describe the effect of CZP on the metabolic and hematologic profiles, and on ES in patients with epilepsy and with psychosis and/or aggressive behavior. 

Methods: A case series of patients with epilepsy and psychosis and/or aggressive behavior that received CZP with an 18-week follow-up. Clinical records were assessed from 2008-2018. 30 patients with epilepsy that received CZP were included. A paired analysis (Student’s t-test or Wilcoxon signed rank test) was performed with metabolic variables (glucose, cholesterol, and triglycerides), hematologic variables, weight, body mass index (BMI), and monthly ES before and after CZP administration.

Results: The median age to CZP initiation was 31.9 ± 16.07 years. Median CZP dosage was 193 mg/day. There were changes on BMI (p = 0.001; 3.2 kg/m2 increase, median = 3.08), triglycerides (p = 0.002) and glucose (p = 0.030). Weight increase was 7 kg (p = 0.292; median = 4 kg). Monthly ES mean was decreased from 4.9 (median = 2) to 2.04 (median = 1; p = 0.001).

Conclusions: This study provide information regarding the security profile of CZP in patients with epilepsy with psychosis and/or aggressive behavior. A decrease on monthly ES was observed, as well as moderate increases in triglycerides, glucose and BMI, which coincide with that described by other authors.
