Neuropsychological predictors of treatment outcome in obsessive compulsive disorder (OCD)

Contexte: En dépit de la preuve substantielle pour l'efficacité générale de la thérapie cognitivo-comportementale pour le trouble obsessionnel-compulsif (TOC), il existe une controverse à propos de l'amélioration de certains déficits neuropsychologiques dans ce trouble. Objectif: Le but de cette étude est d'évaluer: 1) la corrélation de la gravité du TOC et les résultats des tests neuropsychologiques et 2) l'amélioration clinique et neuropsychologique des patients souffrant de TOC qui ont terminé avec succès leur traitement. Méthode: Cette étude évalue les fonctions neurocognitives et l'état clinique de 27 participants du groupe TOC et 25 participants du groupe témoin. La fonction neurocognitive de chaque participant a été évaluée en utilisant le test de Rey-Osterreich Figure complexe (RCFT), le test de fluidité D-KEFS et l’essai Cardebat-D. Nous avons également, utilisé l'inventaire d'anxiété de Beck (IAB), l’Inventaire de dépression de Beck (IDB) et l'échelle d'obsession-compulsion de Yale-Brown (Y-BOCS) pour vérifier la présence de l'anxiété et de la dépression avec le TOC et la gravité des symptômes chez les patients souffrant de TOC. Résultats: Notre étude conclut qu’il y une différence significative de la fonction de la mémoire selon le score au sous test de copie entre les participants souffrant de TOC et le groupe témoin. De plus, nous avons constaté une différence considérable dans le score de rappel immédiat et différé du RCFT avant et après le traitement dans le groupe de TOC. Conclusion: En résumé, la présente étude a démontré que les patients atteints de TOC ont des troubles cognitifs spécifiques et que la thérapie cognitivo-comportementale serait un traitement qui pourrait améliorer, au moins, certaines dysfonctions neurocognitives.Background: Despite substantial evidence supporting the general efficacy of cognitive behavioral therapy for obsessive-compulsive disorder (OSD), there is controversy about improvement in some neuropsychological deficits in this disorder. Objective: The present study aim to evaluate: 1) correlation of severity of OCD and neuropsychological test scores and 2) clinical and neuropsychological improvement of patients with OCD who have successfully completed their treatment. Method: This study evaluates neurocognitive function and clinical condition of 27 participants of OCD group and 25 participants of control group. The neurocognitive function of every participant has been assessed using Rey-Osterreich Complex Figure Test (RCFT), D-KEFS fluency test and Cardebat- D test. We also, used Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and Yale-Brown Obsessive-Compulsive scale(Y-BOCS) to verify comorbidity of anxiety and depression with OCD and severity of symptoms in patients with OCD. Results: Our study concludes that a significant difference of function in copy score is present between OCD and control group. Also, we found considerable difference in score of immediate and delayed recall of RCFT before and after treatment in OCD group. Conclusion: In summary, the present study demonstrated that OCD patients have specific cognitive impairments and cognitive behavioral therapy could improve, at least, some neurocognitive dysfunction

First evidence of the presence of adenovirus type 8 in myocardium of patients with severe idiopathic dilated cardiomyopathy

Previous studies have detected adenovirus and cytomegalovirus (CMV) in cardiac tissue of patients with myocarditis. Therefore, in this study, we investigated the frequency of these viruses, which may be involved in the development of severe dilated cardiomyopathy (DCM). Myocardial tissue from of 23 cardiac transplant candidates with acute idiopathic DCM below the age of 40 years were analyzed by amplification of adenovirus and CMV DNA and subsequent sequencing. Adenovirus was detected in four (17.4%) and CMV in one (4.3%) of the patients. All controls were negative for the presence of both viruses. Our study shows that myocardial infection with adenovirus may play an important role in the pathogenesis of severe DCM and suggests that vaccination against adenovirus might be helpful in decreasing the prevalence of severe idiopathic DCM. This is the first study in which adenovirus type 8 has been detected in the hearts of patients with DCM

The effect of sodium valproate on acetic acid-induced colitis in rats

Ulcerative colitis is a chronic recurrent disease with incomplete treatment options. The current article evaluated the effect of sodium valproate on acetic acid-induced ulcerative colitis in rats. Rats were randomly distributed into six groups including Sham group, colitis control group, sodium valproate treatment groups (50, 100 and 300 mg/kg, i.p.) and dexamethasone-treatment group. Dexamethasone was used as a reference drug. Colitis was induced by intracolonic instillation of 2 mL of 3% acetic acid solution. The efficacy of sodium valproate was evaluated by macroscopical and histopathological scoring systems, hematocrit measurement as well as biochemical analysis including myeloperoxidase (MPO) and pro-inflammatory cytokines assessment. Sodium valproate, particularly with doses of 100 and 300 mg/kg significantly improved weight loss, and macroscopic damage, reduced ulcer area, colon weight, microscopic colitis index and elevated hematocrit level. Biochemical experiments showed elevated levels of colonic MPO activity, interleukin 1 beta (IL-1 beta), interleukin 6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) in colitis control group. Treatment with sodium valproate at the doses of 100 and 300 mg/Kg) decreased the MPO activity and colonic concentrations of IL-1 beta, IL-6 and TNF-alpha. The results provide evidence that sodium valproate has a protective effect in acetic acid-induced ulcerative colitis which might be due to its anti-inflammatory activities, and it may be useful in patients with ulcerative colitis

The effect of theophylline on acetic acid induced ulcerative colitis in rats

Background: Ulcerative colitis is a relapsing inflammatory disorder of the colon. There is a need to explore the new treatments for this disorder. Theophylline, a competitive inhibitor of phosphodiesterase, is shown to have anti-inflammatory properties. However, the effect of theophylline on ulcerative colitis has not yet been investigated. The present study evaluated the effect of theophylline on acetic acid induced ulcerative colitis in rats. Materials and methods: Colitis was induced by instillation of 2 ml of acetic acid solution (3%). Colon samples were evaluated grossly and microscopically and assayed for myeloperoxidase (MPO) activity and proinflammatory cytokine concentrations. Results: Treatment with theophylline at the doses of 20 and 50 mg/kg attenuated acetic acid induced ulcerative colitis as shown by improvement in body weight loss, macroscopic score, ulcer area, hematocrit and histopathological score. Theophylline treatment also reduced MPO activity and tumor necrosis factor-alpha (TNF-alpha), interleukin 1 beta (IL-1 beta) and interleukin 6 (IL-6) concentrations in inflamed colon. Conclusion: Theophylline has a protective effect in acetic acid-induced ulcerative colitis which might be due to its anti-inflammatory activities. Therefore, theophylline has the potential to be used for successful treatment of ulcerative colitis. (C) 2017 Elsevier Masson SAS. All rights reserved
