with trichotillomania

Immune dysregulation may be important in the etiology of obsessive-compulsive and related disordersandbody-focusedrepetitivebehaviors, such as Trichotillomania (TTM). The role of inflammation and inflammatory markers in TTM has received relatively little attention. This study was aimed to determine the expression levels of inflammatory markers (i.e. IL-1 beta, IL-1 alpha, IL-4, IL-6, IL-17, TNF-alpha and TGF-5) in peripheral blood mononuclear cells of children with TTM and healthy controls and to evaluate their association with clinical variables. Seventy-seven patients with TTM and 107 healthy controls were enrolled in the study. Peripheral blood was collected in standardized conditions. The mean age of patients and controls did not differ significantly (10.8 +/- 4.4 and 12.0 +/- 3.2 years; respectively). The majority of patients with TTM and controls were females (n = 55, 71.4 % and n = 55, 51.4 %; respectively); with a greater preponderance of females among TTM. Patients with TTM had significantly elevated expression levels of TNF-alpha, IL-6 and IL-17 compared to controls. However, the expression level of IL-4 was significantly reduced in TTM patients compared to controls. Accordingly, we found a proinflammatory state in TTM and those findings may suggest novel treatment options for TTM and further, crossdisciplinary studies focusing on neuro- inflammation in TTM conducted on larger samples are needed.C1 [Kutuk, Meryem Ozlem] Baskent Univ, Dept Child & Adolescent Psychiat, Dr Turgut Noyan Med & Res Ctr, Adana, Turkey.[Tufan, Ali Evren] Acibadem Mehmet Ali Aydinlar Univ, Dept Child & Adolescent Psychiat, Istanbul, Turkey.[Kilicaslan, Fethiye] Mehmet Akif Inan Educ & Res Hosp, Dept Child & Adolescent Psychiat, Sanliurfa, Turkey.[Mutluer, Tuba] Koc Univ, Dept Child & Adolescent Psychiat, Istanbul, Turkey.[Gokcen, Cem; Topal, Zehra] Gaziantep Univ, Dept Child & Adolescent Psychiat, Gaziantep, Turkey.[Karadag, Mehmet] Mardin State Hosp, Dept Child & Adolescent Psychiat, Mardin, Turkey.[Yektas, Cigdem] Duzce Univ, Dept Child & Adolescent Psychiat, Duzce, Turkey.[Kandemir, Hasan] Celal Bayar Univ, Dept Child & Adolescent Psychiat, Manisa, Turkey.[Buber, Ahmet] Pamukkale Univ, Dept Child & Adolescent Psychiat, Denizli, Turkey.[Aksu, Gulen Guler] Mersin Univ, Dept Child & Adolescent Psychiat, Mersin, Turkey.[Giray, Asli] Alanya Alaaddin Keykubat Univ, Dept Genet & Bioengn, Alanya, Turkey.[Celik, Fatma] Malatya Training & Res Hosp, Dept Child & Adolescent Psychiat, Malatya, Turkey.[Acikbas, Ufuk; Kutuk, Ozgur] Baskent Univ, Dept Med Genet, Adana Dr Turgut Noyan Med & Res Ctr, Adana, Turkey

Novel inflammatory targets for immunotherapies in pediatric patients with trichotillomania.

Immune dysregulation may be important in the etiology of obsessive-compulsive and related disordersandbody-focusedrepetitivebehaviors, such as Trichotillomania (TTM). The role of inflammation and inflammatory markers in TTM has received relatively little attention. This study was aimed to determine the expression levels of inflammatory markers (i.e. IL-1β, IL-1α, IL-4, IL-6, IL-17, TNF-α and TGF-β) in peripheral blood mononuclear cells of children with TTM and healthy controls and to evaluate their association with clinical variables. Seventy-seven patients with TTM and 107 healthy controls were enrolled in the study. Peripheral blood was collected in standardized conditions. The mean age of patients and controls did not differ significantly (10.8 ± 4.4 and 12.0 ± 3.2 years; respectively). The majority of patients with TTM and controls were females (n = 55, 71.4 % and n = 55, 51.4 %; respectively); with a greater preponderance of females among TTM. Patients with TTM had significantly elevated expression levels of TNF-α, IL-6 and IL-17 compared to controls. However, the expression level of IL-4 was significantly reduced in TTM patients compared to controls. Accordingly, we found a pro-inflammatory state in TTM and those findings may suggest novel treatment options for TTM and further, cross-disciplinary studies focusing on neuro- inflammation in TTM conducted on larger samples are needed

Cytokine expression profiles in Autism spectrum disorder: A multi-center study from Turkey.

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder characterized by impairments in communication and social interaction as well as restricted interests and repetitive behaviors. The pathogenesis of ASD is not completely understood, but a growing body of research has demonstrated that the immune response may be a contributing factor in the etiology and/ or ontogeny of ASD. The aim of this study was to determine the expression levels of IL-1β, IL-1α, IL-4, IL-6, IL-17, TNF-α and TGF-β in peripheral blood mononuclear cells of children with ASD and healthy controls in order to determine the contributions of cytokines to ASD. Within the study timeframe, 195 children with ASDs (80.5% male) and 162 controls (73.6% male) were enrolled. Most children with ASD had a comorbid disorder (n = 114, 58.5%), with the most common diagnoses as Intellectual Developmental Disorder (IDD, n = 64, 32.8%) and ADHD (n = 64, 32.8%). The majority of children with ASD had severe autistic symptoms as evaluated via Childhood Autism Rating Scale (CARS, n = 130, 64.6%). The mean CARS score in the ASD sample was 40.8 (S.D. = 7.6). The patients with ASD were found to have significantly higher levels of IL-6 (p < 0.001) and significantly lower levels of IL-17 (p < 0.05, all Bonferroni corrected). Treatment tended to affect IL-4 levels. Lastly, discriminant function analysis (DFA) revealed that a combination of IL-6, IL-17 and IL-1α correctly classified 56.6% of cases. Despite extensive immunological evidence suggesting immune system aberrations, further research is required to clarify the relationship between immune profiles and ASD symptoms
