The complementary role of high sensitivity C-reactive protein in the diagnosis and severity assessment of autism / Mohammad Reza KHAKZAD in Research in Autism Spectrum Disorders, 6-3 (July-September 2012)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 6-3 (July-September 2012) . - p.1032-1037 Titre : The complementary role of high sensitivity C-reactive protein in the diagnosis and severity assessment of autism Type de document : Texte imprimé et/ou numérique Auteurs : Mohammad Reza KHAKZAD, Auteur ; Maryam JAVANBAKHT, Auteur ; Mohammad Reza SHAYEGAN, Auteur ; Sina KIANOUSH, Auteur ; Fatemeh OMID, Auteur ; Maryam HOJATI, Auteur ; Mojtaba MESHKAT, Auteur Année de publication : 2012 Article en page(s) : p.1032-1037 Langues : Anglais (eng) Mots-clés : Autistic disorder  C-reactive protein  Inflammation  Severity Index. décimale : PER Périodiques Résumé : C-reactive protein (CRP) is a beneficial diagnostic test for the evaluation of inflammatory response. Extremely low levels of CRP can be detected using high-sensitivity CRP (hs-CRP) test. A considerable body of evidence has demonstrated that inflammatory response has an important role in the pathophysiology of autism. In this study, we evaluated and compared hs-CRP levels between autistic and intellectually normal individuals. Clinical data of 39 autistic and 30 age-matched intellectually normal individuals (control group) were recorded. Patients were divided into two groups (mild-to-moderate and severe) according to childhood autism rating scale. Then serum hs-CRP concentrations were measured and compared between two groups. Also, the correlation between hs-CRP concentration and the severity of autism was determined. The mean concentration of hs-CRP in children with autism (540.1 ± 1125.5 ng/ml) was significantly (P < 0.0001) higher than control group (1.3 ± 1.0 ng/ml). In severe autism, the mean level of hs-CRP (985.1 ± 1432.1 ng/ml) was significantly (P = 0.008) higher than the mean level of hs-CRP in patients with mild-to-moderate autism (147.1 ± 60.4 ng/ml). There was a positive correlation between hs-CRP concentration and autism severity (r = 0.34; P = 0.039). These findings affirm the role of inflammation in autism.

Characterizing competence among a high-risk sample of emerging adults: Prospective predictions and biological considerations / Justin RUSSOTTI in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1937-1953 Titre : Characterizing competence among a high-risk sample of emerging adults: Prospective predictions and biological considerations Type de document : Texte imprimé et/ou numérique Auteurs : Justin RUSSOTTI, Auteur ; Jennifer M.

Furthermore, child maltreatment tends to co-occur with other adversities, such as poverty. Many individuals grow up under the stressful conditions of these adversities and exhibit developmental competence. The current study prospectively charted the developmental progression of economically disadvantaged maltreated and nonmaltreated children from childhood to emerging adulthood, and examined patterns of competence across multiple developmental domains of functioning central to the period of emerging adulthood. The study investigated childhood precursors to these patterns of adaptation and maladaptation, as well as the physiological cost of these patterns of adaptation (i.e., C-reactive protein; CRP). Latent class analysis revealed four distinct classes of functioning: multifaceted competence across domains (Multifaceted Competence); (multifaceted maladaptation across domains (Multi-Problem); (c) and two classes with mixed patterns of competence and maladaptation (Externalizing Problems and Work/School Impairment). Maltreated individuals were less likely than nonmaltreated individuals to demonstrate patterns of multifaceted competence and more likely to demonstrate aggregate maladaptation across domains. Additionally, Black men who demonstrated a pattern of multifaceted psychosocial competence also evidenced higher levels of low-grade inflammation (indexed by CRP), suggesting physiological distress was associated with adaptation in the context of stress among these individuals. Findings demonstrate the heterogenous patterns of functioning and diverse developmental outcomes that follow early adversity.

Immediate and longitudinal effects of maltreatment on systemic inflammation in young children / Sonja ENTRINGER in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1725-1731 Titre : Immediate and longitudinal effects of maltreatment on systemic inflammation in young children Type de document : Texte imprimé et/ou numérique Auteurs : Sonja ENTRINGER, Auteur ; Karin DE PUNDER, Auteur ; Judith OVERFELD, Auteur ; Gergana KARABOYCHEVA, Auteur ; Katja DITTRICH, Auteur ; Claudia BUSS, Auteur ; Sibylle Maria WINTER, Auteur ; Elisabeth B.

Inflammation has been proposed as a mechanism through which early adverse experiences become biologically embedded. However, most studies providing evidence for the link between early adverse exposures and inflammation have been retrospective or cross-sectional in design, or did not assess inflammation immediately after maltreatment in young children. In the present study we investigated the association between childhood maltreatment and salivary C-reactive protein (CRP) concentrations in a population of N = 173 children, 3-5 years of age, who were recruited in the immediate aftermath of maltreatment and followed-up longitudinally every 6 months over a period of 2 years. We found that the association between maltreatment and CRP concentrations was significantly moderated by child sex, such that in girls, CRP concentrations were higher in the maltreated compared to the control group, and this difference was stable across the 2-year follow-up-period, while in boys, there was no association between maltreatment and CRP. Our findings suggest that the effect of maltreatment on inflammation may already emerge right after exposure at a very young age in girls and manifest over time. Our study provides important evidence for the development of personalized, early interventions strategies targeting the early-life period.

Pathways between early-life adversity and adolescent self-harm: the mediating role of inflammation in the Avon Longitudinal Study of Parents and Children / A. E. RUSSELL in Journal of Child Psychology and Psychiatry, 60-10 (October 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-10 (October 2019) . - p.1094-1103 Titre : Pathways between early-life adversity and adolescent self-harm: the mediating role of inflammation in the Avon Longitudinal Study of Parents and Children Type de document : Texte imprimé et/ou numérique Auteurs : A.

MARS, Auteur Article en page(s) : p.1094-1103 Langues : Anglais (eng) Mots-clés : Avon Longitudinal Study of Parents and Children  C-reactive protein  Inflammation  Self-harm  adverse childhood experiences  interleukin-6  mediation  suicide Index. décimale : PER Périodiques Résumé : BACKGROUND: Adverse childhood experiences (ACEs) such as physical and emotional abuse are strongly associated with self-harm, but mechanisms underlying this relationship are unclear. Inflammation has been linked to both the experience of ACEs and self-harm or suicide in prior research. This is the first study to examine whether inflammatory markers mediate the association between exposure to ACEs and self-harm. METHODS: Participants were 4,308 young people from the Avon Longitudinal Study of Parents and Children (ALSPAC), a population-based birth cohort in the United Kingdom. A structural equation modelling approach was used to fit a mediation model with the number of ACEs experienced between ages 0 and 9 years old (yo), levels of the inflammatory markers interleukin-6 and C-reactive protein measured at 9.5 yo, and self-harm reported at 16 yo. RESULTS: The mean number of ACEs young people experienced was 1.41 (SE 0.03). Higher ACE scores were associated with an increased risk of self-harm at 16 yo (direct effect relative risk (RR) per additional ACE 1.11, 95% CI 1.05, 1.18, p < 0.001). We did not find evidence of an indirect effect of ACEs on self-harm via inflammation (RR 1.00, 95% CI 1.00, 1.01, p = 0.38). CONCLUSIONS: Young people who have been exposed to ACEs are a group at high risk of self-harm. The association between ACEs and self-harm does not appear to be mediated by an inflammatory process in childhood, as indexed by peripheral levels of circulating inflammatory markers measured in childhood. Further research is needed to identify alternative psychological and biological mechanisms underlying this relationship.
