Multiple regression analysis confirmed the associations between the body mass index and all measured body compositions. Furthermore, the diagnosis of schizophrenia is significantly associated with lower muscle mass, lower bone mass, higher basal metabolic rate, older metabolic age, and higher total body water.

It is possible that in vivo Hcy is only a marker of folate metabolism disturbances (which are involved in methylation processes) and is not a pathogenetic factor per se. Only one study has been conducted in which associations of hyperhomocysteinemia with oxidative stress in schizophrenia (oxidative damage to protein and lipids) have been found, and it has been suggested that the oxidative stress may be induced by the elevated Hcy in schizophrenic patients. But the authors did not study the level of reduced glutathione (GSH), as well as possible causes of hyperhomocysteinemia-disturbances of folate metabolism. The aim of this work is to analyze the association of Hcy levels with the following: (1) redox markers in schizophrenia GSH, markers of oxidative damage of proteins and lipids, and the activity of antioxidant enzymes in blood serum; (2) with the level of folate and cobalamin (В12); and (3) with clinical features of schizophrenia measured using the Positive and Negative Syndrome Scale (PANSS). 50 patients with schizophrenia and 36 healthy volunteers, matched by sex and age, were examined. Hcy in patients is higher than in healthy subjects (&lt;i&gt;p&lt;/i&gt; = 0.0041), and this may be due to the lower folate level in patients (&lt;i&gt;p&lt;/i&gt; = 0.0072). In patients, negative correlation was found between the level of Hcy both with the level of folate (&lt;i&gt;ρ&lt;/i&gt; = -0.38, &lt;i&gt;p&lt;/i&gt; = 0.0063) and with the level of B12 (&lt;i&gt;ρ&lt;/i&gt; = -0.36, &lt;i&gt;p&lt;/i&gt; = 0.0082). At the same time, patients showed higher levels of oxidative modification of serum proteins (&lt;i&gt;p&lt;/i&gt; = 0.00046) and lower catalase (CAT) activity (&lt;i&gt;p&lt;/i&gt; = 0.014). However, Hcy is not associated with the studied markers of oxidative stress in patients. In the group of patients with an increased level of Hcy (&gt;10 &lt;i&gt;μ&lt;/i&gt;mol/l, &lt;i&gt;n&lt;/i&gt; = 42) compared with other patients (&lt;i&gt;n&lt;/i&gt; = 8), some negative symptoms (PANSS) were statistically significantly more pronounced: difficulty in abstract thinking (N5, &lt;i&gt;p&lt;/i&gt; = 0.019), lack of spontaneity and flow in conversation (N6, &lt;i&gt;p&lt;/i&gt; = 0.022), stereotyped thinking (N7, &lt;i&gt;p&lt;/i&gt; = 0.013), and motor retardation (G7, &lt;i&gt;p&lt;/i&gt; = 0.050). Thus, in patients with schizophrenia, hyperhomocysteinemia caused by deficiency of folate and B12 is confirmed and can be considered a marker of disturbances of vitamin metabolism. The redox imbalance is probably not directly related to hyperhomocysteinemia and is hypothetically caused by other pathological processes or by an indirect effect of Hcy, for example, on the enzymatic antioxidant defence system (CAT activity), which requires further exploration. Further study of the role of Hcy in the pathogenesis of schizophrenia is relevant, since the proportion of patients with hype","PeriodicalId":45388,"journal":{"name":"Schizophrenia Research and Treatment","volume":"2021 ","pages":"7721760"},"PeriodicalIF":2.4,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8545596/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39567149","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}

This social anxiety disorder negatively impacts the quality of life, medication adherence, and treatment outcomes of people with schizophrenia. It is not well recognized in clinical settings. Therefore, assessing social anxiety symptoms and its associated factors was significant to early intervention and management of schizophrenia patients in Ethiopia.</p><p><strong>Methods: </strong>An institution-based cross-sectional study was conducted at Amanuel Mental Specialized Hospital in Addis Ababa, Ethiopia. Data collectors randomly recruited 423 schizophrenic patients by using the systematic sampling technique. A face-to-face interviewer-administered questionnaire was used to collect data. The standardized Liebowitz Social Anxiety Scale (LSAS) was employed to assess individual social anxiety symptoms. We computed bivariate and multivariate binary logistic regressions to identify factors associated with social anxiety symptoms. Statistical significance was declared at <i>p</i> < 0.05.</p><p><strong>Results: </strong>The prevalence of social anxiety symptoms was 36.2% (95% CI: 31.50, 40.80).
