RESUMEN
Objetivos: Analizar los efectos de los inhibidores de colinesterasas (ICE) donepezilo, rivastigmina y galantamina en el tratamiento de demencia con cuerpos de Lewy (DCL) y demencia de la enfermedad de Parkinson (DEP). Diseño: Estudio tipo ensayo abierto. Lugar: Servicio de Neurología, Hospital Militar Central (HMC), y Unidad de Diagnóstico de Deterioro Cognitivo y Prevención de Demencia, Clínica Internacional. Participantes: Pacientes con demencia asociada a cuerpos de Lewy y demencia de la enfermedad de Parkinson. Intervenciones: Las mediciones de eficacia en 33 pacientes con diagnóstico de DCL y DEP se realizó con el Mini-Mental State Examination (MMSE), Alzheimer Disease Assessment Scale cognitive subscale (ADAS-cog), Alzheimer’s Disease Cooperative Study-Clinical Global Impression of Change (ADCS-CGIC), Alzheimer’s Disease Cooperative Study-Activities of Daily Living Inventory (ADCS-ADL), Neuro-Psychiatry Inventory (NPI), Prueba de dibujo de Reloj de Manos (PDR-M) y la Unified Parkinson ́s Disease Rating Scale- motor subscale (UPDRS-part III). Principales medidas de resultados: Síntomas cognitivos, funcionamiento global y actividades de vida diaria de los pacientes. Resultados: Diecisiete pacientes fueron tratados con rivastigmina, 9 con galantamina y 7 con donepezilo. Luego de 6 meses de tratamiento, los pacientes en tratamiento con rivastigmina mejoraron en 1,39 puntos en ADAS-cog respecto de su medición basal, mientras que los pacientes tratados con donepezilo y galantamina no mostraron cambios (cambios <0,2 puntos). Respecto al ADCS-ADL, los pacientes tratados con rivastigmina, donepezilo y galantamina demostraron disminución de 0,42, 0,58 y 0,75 puntos, respectivamente. En el MMSE, los pacientes tratados con rivastigmina y donepezilo no mostraron cambios y los pacientes tratados con galantamina tuvieron una disminución promedio de 1,19 puntos. No hubo diferencias significativas en la incidencia de síntomas parkinsonianos en los tres grupos de tratamiento. Los eventos adversos fueron similares en los tres grupos de tratamiento. Conclusiones: Los inhibidores de colinesterasa pueden ser benéficos en el manejo de síntomas cognitivos, el funcionamiento global y actividades de vida diaria en pacientes con demencia con cuerpos de Lewy y demencia de la enfermedad de Parkinson. Palabras clave: Enfermedad de Parkinson; demencia con cuerpos de Lewy; inhibidores de colinesterasa; demencia; terapia.

ABSTRACT
Objectives: To analyze the effects of cholinesterase inhibitors (CHEIs) prescribed for treatment of dementia with Lewy bodies (DLB) and dementia associated with Parkinson’s disease (PDD). Design: Open essay study. Setting: Neurology Service, Hospital Militar Central, and Cognitive Deterioration Diagnosis Unit and Dementia Prevention, Clinica Internacional. Participants: Patients with dementia associated to Lewy bodies and dementia associated with Parkinson’s disease. Interventions: Outcome measures included the Mini-Mental State Examination (MMSE), the Alzheimer Disease Assessment Scale cognitive subscale (ADAS-cog), Alzheimer’s Disease Cooperative Study-Clinical Global Impression of Change (ADCS-CGIC), Alzheimer’s Disease Cooperative Study-Activities of Daily Living Inventory (ADCS-ADL), Neuro-Psychiatry Inventory (NPI), Ten Point Clock-Drawing Test (CDT) and Unified Parkinson´s Disease Rating Scale-motor subscale (UPDRS-part III). Main outcome measures: Patients’ cognitive symptoms, global function and daily life activities. Results: Seventeen patients were treated with rivastigmine, nine with galantamine and seven with donepezil. At six months, rivastigmine-treated patients improved by 1,39 points from baseline on the ADAS-cog, while donepezil and galantamine treated patients showed ‘no change’ (changes of <0,2 points). On the ADCS-ADL, patients treated with rivastigmine, donepezil and galantamine showed decreases of 0,41, 0,68 and 0,86 points, respectively. On the MMSE, donepezil and rivastigmine-treated patients showed ‘no change’ and galantamine-treated patients showed a mean decrease of 1,19 points. The difference with regard to the incidence of parkinsonian symptoms as adverse events was not reflected in significant differences in UPDRS motor scores between the three groups. Side effects were similar in the three treatment groups. Conclusions: Cholinesterase inhibitors may be of benefit for cognitive impairments with impact on global function and activities of daily living in patients with dementia with Lewy bodies and dementia associated with Parkinson’s disease.
