It has been found to exhibit a high incidence of comorbidity with epilepsy, the exact underlying pathophysiology of which still remains poorly understood. OSA is characterized by apnea/hypopnea spells and arousals, leading to intermittent hypoxemia and sleep deprivation. Both sleep deprivation and hypoxemia adversely affect the cortical excitability and favor epileptogenesis and worsening of pre-existing epilepsy, if any. In patients with OSA, deprivation of rapid eye movement sleep (REMS) phase (known for its strong antiepileptic influence) is relatively more than that non rapid eye movement sleep phase leading to postulation of REMS deprivation as a significant factor in the development of epilepsy as a comorbidity in patients with OSA. Furthermore, OSA and epilepsy both have shown to exercise a bidirectional influence on one another and are also likely to exacerbate each other through a positive feedback mechanism. This is especially based on the reports of improved control of epilepsy upon treatment of comorbid OSA.

However, the underlying neuronal mechanisms that contribute to the difference are mostly unexplored. Although more men suffer from alcohol use disorders (AUD), women more frequently accelerate to dependence and develop adverse consequences of alcoholism sooner than men. Women also exhibit more significant negative emotions that cues more reactivity and alcohol-craving than men. Despite ample evidence that women are vulnerable to AUD, results of preclinical studies on sex differences in alcohol consumption and withdrawal-related behaviors are inconclusive. In this study, we trained adult male and female Sprague-Dawley rats to drink alcohol in the intermittent access to 20% ethanol two-bottle free-choice paradigm for two months. Their behaviors and Fos expression in related brain regions were measured at acute (24 h) and after prolonged (28 days) abstinence. We found that female rats drank more alcohol than males. After acute abstinence, rats of both sexes showed higher sensitivity to depressive, thermal, and mechanical stimuli. Females also displayed higher anxiety levels. After prolonged abstinence, rats of both sexes displayed depressive-like behaviors; the males displayed allodynia; the females showed higher anxiety levels and drank more alcohol upon reaccess to alcohol. Furthermore, during acute withdrawal, Fos-positive nuclei were increased in the prefrontal cortex, anterior cingulate cortex (ACC), nucleus accumbens (NAc), amygdala and lateral habenula (LHb) in the females, versus only in the ACC, amygdala, and LHb in the males. Conversely, after prolonged abstinence, Fos-positive nuclei were decreased in the prefrontal cortex, ACC, and NAc in the females, but fell in the ACC, NAc, and LHb of the males. Thus, adaptations in diverse brain regions may contribute to the sex differences in behaviors in ethanol-withdrawn rats.</p>","PeriodicalId":94056,"journal":{"name":"International journal of physiology, pathophysiology and pharmacology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6737432/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140864770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a strong link between hyperglycaemia, hyperglycaemic-induced oxidative stress, inflammation and the development and progression of type 2 diabetes mellitus. Various reports have shown that chronic low-grade inflammation is associated with the risk of developing type 2 diabetes and that sub-clinical inflammation contributes to insulin resistance and is linked to the characteristics of metabolic syndrome which include hyperglycaemia. Oxidative stress stimulates the generation of inflammatory mediators and inflammation in turn enhances the production of reactive oxygen species. This interaction between diabetes, oxidative stress and inflammation is the primary motivation for the compilation of this review.
