Serum Ischemia-Modified Albumin Levels, Myeloperoxidase Activity and Peripheral Blood Mononuclear cells in Autism Spectrum Disorder (ASD) / Mehmet Fatih CEYLAN in Journal of Autism and Developmental Disorders, 51-7 (July 2021)
[article]
Titre : Serum Ischemia-Modified Albumin Levels, Myeloperoxidase Activity and Peripheral Blood Mononuclear cells in Autism Spectrum Disorder (ASD) Type de document : Texte imprimé et/ou numérique Auteurs : Mehmet Fatih CEYLAN, Auteur ; S. TURAL HESAPCIOGLU, Auteur ; C. P. YAVAS, Auteur ; A. SENAT, Auteur ; O. EREL, Auteur Article en page(s) : p.2511-2517 Langues : Anglais (eng) Mots-clés : Adolescent Adult Autism Spectrum Disorder/blood Biomarkers/blood Case-Control Studies Child Child, Preschool Humans Leukocytes, Mononuclear Male Monocytes/immunology Oxidative Stress Peroxidase/blood Serum Albumin Serum Albumin, Human Asd Autism spectrum disorder Ima Ischemia-modified albumin Lymphocytes Monocytes Myeloperoxidase Neutrophils Index. décimale : PER Périodiques Résumé : Genetic, neurobiological, neurochemical, environmental factors and their interactions contribute to autism phenotypes. Blood from 48 (age range: 4-17) autism spectrum disorder diagnosed patients (ASD) and 38 age- and gender-matched healthy control subjects was analyzed for numbers of neutrophils, lymphocytes, monocytes, albumin, serum Ischemia-Modified Albumin (IMA) levels and myeloperoxidase activity. The serum IMA levels, myeloperoxidase activity and peripheral blood mononuclear cells count were significantly higher in ASD cases than in the control subjects. There were no significant differences in albumin levels between the patient and control groups. These results suggest that the immune system, oxidative stress and myeloperoxidase activity may be activated in ASD. There is a clinical benefit from the early detection of ASD using myeloperoxidase activity, IMA levels and monocyte counts.

This study was performed to identify inflammatory indicators useful for diagnosing ASD. The mRNA expression of cytokines, including tumor necrosis factor-? (TNF-?), was measured in cultured M1 and M2 macrophages from patients with ASD (n = 29) and typically developed (TD) individuals (n = 30). Additionally, TNF-? expression in the monocytes of patients with ASD (n = 7), showing aberrations in TNF-? expression in M1/M2 macrophages and TD individuals (n = 6), was measured. TNF-? expression in M1 macrophages and the TNF-? expression ratio in M1/M2 macrophages were markedly higher in patients with ASD than in TD individuals; however, this increase was not observed in M2 macrophages (M1: sensitivity = 34.5%, specificity = 96.7%, area under the curve = 0.74, positive likelihood ratio = 10.34; ratio of M1/M2: sensitivity = 55.2%, specificity = 96.7%, area under the curve = 0.79, positive likelihood ratio = 16.55). Additionally, TNF-? expression in monocytes did not significantly differ between patients with ASD and TD individuals. In conclusion, further studies on TNF-? expression in cultured macrophages may improve the understanding of ASD pathobiology. LAY SUMMARY: TNF-? expression in differentiated M1 macrophages and TNF-? expression ratio in differentiated M1/M2 macrophages were markedly higher in patients with ASD than in TD individuals, while no difference in TNF-? expression was found in pre-differentiation cells such as monocytes. These measurements allow elucidation of the novel pathobiology of ASD and can contribute to biomarker implementation for the diagnosis of adult high-functioning ASD.
