Several studies report the problem of cardiovascular tolerance of treatments with neuroleptics, given the important number of morbidities in patients with mental illnesses. This preliminary work aimed to describe the epidemiological and biological profile of patients taking neuroleptics and followed in the psychiatry department of Brazzaville University Hospital, from the angle of cardiovascular risk. Fifty (50) patients (17 men and 33 women), with a mean age of 33.9 10.7 years, were included. Epidemiological data (sex, age, tobacco or alcohol consumption) were collected on pre-established survey forms. Biochemical (total cholesterol, HDL-c, triglycerides and atherogenicity index) and inflammatory parameters (ultra-sensitive CRP, troponin I and NT-ProBNP) were investigated using enzymatic and indirect immunofluorescence technical, respectively. The results obtained showed that 54% of patients were obese, 94% were non-smokers, and 12% had high blood pressure. 10% of patients had high total cholesterol levels and 90% had HDL cholesterol levels below 60 mg/dl. Triglycerides and atherogenicity index were significantly elevated in relation to Body Mass Index (BMI). Ultrasensitive CRP was elevated in 38% of patients. In conclusion, this study revealed an association between lipid parameters (triglycerides and atherogenicity index) in relation to BMI in patients taking neuroleptics followed in the psychiatry department of University Hospital Center of Brazzaville.

Cytokines including tumor necrosis factor, interleukins, interferons, and chemokines are abundantly produced in various diseases. As pleiotropic factors, cytokines are involved in nearly every aspect of cellular functions such as migration, survival, proliferation, and differentiation. Oligodendrocytes are the myelin-forming cells in the central nervous system and play critical roles in the conduction of action potentials, supply of metabolic components for axons, and other functions. Emerging evidence suggests that both oligodendrocytes and oligodendrocyte precursor cells are vulnerable to cytokines released under pathological conditions. This review mainly summarizes the effects of cytokines on oligodendrocyte lineage cells in central nervous system diseases. A comprehensive understanding of the effects of cytokines on oligodendrocyte lineage cells contributes to our understanding of central nervous system diseases and offers insights into treatment strategies.

Early-life stress(ELS)refers to a period of environmental/social deprivation,physica l,sexual or emotional abuse,neglect,severe and/or chronic trauma in the prenatal/early postnatal stage,which is closely related to many adverse psychiatric disorders later in life,such as depressive disorder,substance abuse,dysthymia,panic,anxiety,and suicidal behavior in adulthood(Waters and Gould,2022).
