Abstract

Introduction: Previous studies approved the important roles of CD68, as scavenger receptors, in Alzheimer's disease (AD). The aim of this study was to evaluate the effect of treatment with anti-psychotic drugs and vitamin B12 on the expression levels of CD68 in monocytes of psychotic AD patients. Material and methods: Expression of CD68 on the monocytes was evaluated in the following groups: 1. age and sex matched healthy controls (Group 1), 2. non-psychotic AD patients (Group 2), 3. psychotic AD patients (Group 3), 4. psychotic AD patients treated with Risperidone (Group 4), 5. psychotic AD patients treated with Risperidone plus vitamin B12 (Group 5), 6. psychotic AD patients treated with Quetiapine (Group 6), psychotic AD patients treated with Quetiapine plus vitamin B12 (Group 7). The expression of CD68 has been performed using flow cytometry technique. Results: The results showed that CD68 levels were significantly increased in AD patients in comparison to healthy controls and in psychotic AD patients in comparison to non-psychotic AD patients. Treatment with anti-psychotic drugs decreased the expression of CD68. Expression of CD68 has a positive correlation with pain, dementia and mental disorders symptoms in psychotic AD patients. Discussion: CD68 may play key roles in the pathogenesis of AD and its complications may be via induction of inflammation. Therefore, it may be concluded that CD68 may be considered as a risk factor for development of AD and also psychotic symptoms in the patients. (C) 2017 Elsevier Inc. All rights reserved.
