Obesity has several negative effects on the psychological status, and the severity of psychological disorders correlates with the degree of obesity. OBJECTIVE Aim of this review is to provide an overview of the literature concerning the psychological distress associated with severe obesity, which contributes to deterioration of the quality of life of affected patients. METHODS Dysfunctional eating behaviours and eating disorders, psychiatric comorbidity, cognition and quality of life will be discussed together with the most common drugs that can be employed to treat the various disorders in this peculiar clinical setting. The effects of bariatric surgery will be also reviewed. RESULTS Obesity is often the result of pathological behaviours implemented in an eating disorder. Inconsistent results have been reported with regard to the effect of severe obesity on cognition, which recognize a multifaceted aetiology. Serotonergic agents play an important role in the management of patients with obesity and binge episodes, fluoxetine being currently a drug approved for this disorder. The efficacy of lorcaserin, a combination of bupropion and naltrexone, or antiepileptic medications (topiramate and zonisamide) has also been proposed. A neuroprotective role of leptin and oestrogen has been hypothesized. Bariatric surgery is a helpful treatment of morbid obese patients, with long-term favourable results on the psychopathological profile. CONCLUSION Psychological, psychoeducational and psychopharmacological treatment can facilitate weight loss in morbid obese subjects with psychopathological comorbidities. A precise definition of the mechanisms affecting appetite, satiety and energy balance is expected to foster the development of new effective antiobesity drugs.","PeriodicalId":89474,"journal":{"name":"Recent patents on endocrine, metabolic & immune drug discovery","volume":"39 1","pages":"112-118"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85955292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among other platforms, inflammasomes are part of a superfamily of Pattern Recognition Receptors (PRR) and act as cytoplasmatic sensors for stimulation with Pathogen Associated Molecular Pattern (PAMPs) and/or Danger/Damage-Associated Molecular Patterns (DAMPs) leading to an infectious/ pathogenic or sterile inflammation. Inflammasomes constitute a complex platform with high molecular weight and functionality, divided into two families: NOD-like or NLR and PYHIN (pyrin and HIN200 - hematopoietic interferoninducible nuclear antigens). After activation by PAMPs or DAMPs, NLRP3 inflammasome promotes conversion of procaspase 1 in caspase-1 to form the active complex which is able to cleave pro-IL-1β and pro-IL-18 in respective active inflammatory cytokines IL-1β and IL-18 inducing cellular death by pyroptosis. Diabetes has a very intricate pathology with metabolic adaptation and inflammatory components apparently responsible for diabetic complications.\u0000\u0000\u0000OBJECTIVE\u0000The present review evaluates the role of inflammasome, emphasizing NRLP3 on diabetes. An overview on several inflammatory diseases in which inflammasomes appear to play a role is included.
