Função endotelial e perfil lipídico de pessoas com esquizofrenia participantes de um programa de emprego apoiado

Abstract

Background:The social function of individuals with schizophrenia is usually poor and this population exhibits a sedentary lifestyle. Social participation, inclusion in the world of work in particular, might favorably interfere with the lives of these individuals by reducing sedentarism and improving their state of health. Objective: To analyze the lipid profile and endothelial function markers among individuals with schizophrenia enrolled in a supported employment program. Methods: Quantitative quasi-experimental study conducted with 14 individuals with schizophrenia enrolled in a labor inclusion program. Participants were assessed before enrolment (time-point 1) and one year later (time-point 2). Total cholesterol and fractions, triglycerides, serum nitrates and nitrites (endothelial function markers) were measured. The data were analyzed with software SPSS 20. Results: The high-density lipoprotein (HDL) and low-density lipoprotein (LDL) levels exhibited significant changes one year after inclusion in the labor market. HDL increased from 82.30 to 98.60 mg/dL (p<0.01) and LDL decreased from 54.50 to 44.45 mg/dL (p<0.02). The triglyceride and total cholesterol levels remained stable. The nitrate and nitrite level exhibited significant reduction from 15.20 to 14.48 µMol (p<0.01). Conclusion: Participation in the supported employment program might have favorably influenced the participants' lipid profile and endothelial function. Nitrites have been described as mediators in the neural inflammatory process, and reduction of their levels is associated with better prognosis of chronic diseases such as schizophrenia. Keywords | schizophrenia; endothelium; work; cholesterol. RESUMO | Introdução:Pessoas com esquizofrenia habitualmente têm um funcionamento social empobrecido e são sedentárias. A participação social, especialmente a inclusão no universo do trabalho, pode interferir positivamente na vida dessas pessoas, reduzindo o sedentarismo e melhorando sua saúde. Objetivo: Avaliar o perfil lipídico e os marcadores da função endotelial de pessoas com esquizofrenia participantes de um programa de emprego apoiado. Método: Pesquisa quantitativa do tipo quase-experimental que avaliou um grupo de 14 sujeitos com esquizofrenia participantes de um programa de inclusão laboral. Os sujeitos foram avaliados antes de ingressarem no programa (momento 1) e um ano depois (momento 2). Foram dosados: colesterol total e frações, triglicerídeos, nitritos e nitratos séricos (marcadores da função endotelial). Os dados foram analisados com o auxílio do software SPSS 20. Resultados: As frações de colesterol high density lipoprotein (HDL-C) e low density lipoprotein (LDL-C) sofreram modificações significativas após o período de um ano de inserção no mercado de trabalho. O HDL aumentou de 82,30 para 98,60 mg/dL (p<0,01). Já o LDL apresentou uma redução de 54,50 para 44,45 mg/dL (p<0,02). Os triglicerídeos e o colesterol total mantiveram-se estáveis. Com relação aos nitritos e nitratos, houve diminuição significativa de 15,20 para 14,48 µmol (p<...

Benefits and Meaning of Lipids Profile in Relation to Oxidative Balance and Brain Morphology in Schizophrenia

“…Moreover, the first episode of SZ correlates with reductions in the essential omega-3 and omega-6 series of polyunsaturated fatty acids (PUFA) in erythrocytes membranes [20]. The same tendency was common for the pathogenesis of bipolar disorder [23].…”

“…One of the important doubts appearing in the literature is to what extent schizophrenia is a disorder of the brain itself, manifested in the psychosocial functioning of the patient, and to what extent it is a systemic disorder in which pathophysiological phenomena concern not only the central nervous system but also the periphery. In recent years, the lipid profile, endothelial function, and role of oxidative stress have been widely discussed in the literature in the context of SZ pathogenesis as well as its spectrum disorders [12,18,20]. Metabolic disturbances are common in SZ.…”
