概括
无质饮食可能会改善精神分裂症和相关疾病 (SRD) 患者的无和排泄等负面症状,这些患者具有高抗 gliadin 抗体 (AGA IgG). 需要进一步的研究来证实这些发现,并探索治疗机制.
科学领域:
- 精神病学是一个精神病学.
- 免疫学 免疫学 免疫学
- 营养科学 营养科学
背景情况:
- 精神分裂症和相关疾病 (SRD) 呈现出负面症状 (例如,无神经,排斥),缺乏FDA批准的治疗方法.
- 一个小组的SRD患者表现出高的炎症和抗 gliadin 抗体 (AGA IgG).
- 以前的小型试验表明,去除质可能会改善这一亚组的负面症状.
研究的目的:
- 确认无质饮食 (GFD) 在改善高AGAIgG水平的SRD患者的负面症状方面的有效性.
- 评估GFD对这一群体认知功能和安全的影响.
主要方法:
- 一个为期5周的双盲,安慰剂对照试验,涉及39名SRD患者,其AGAIgG水平升高.
- 参与者接受了GFD或含质饮食 (GCD),每天添加质或大米粉添加到蛋白质摇中.
- 主要结果使用临床评估面试对负面症状 (CAINS) 动机和快乐 (MAP) 尺度进行测量.
主要成果:
- 与GCD组相比,在GFD组观察到CAINS MAP得分的显著改善 (p=0.045).
- 在其他评估措施中没有发现重大变化,包括CAINS表达性,SANS,BPRS或MCCB.
- GFD被很好地容忍,常见的副作用包括便秘和镇静.
结论:
- 这项试验提供了证据,证明GFD可以改善AGA IgG的SRD患者的负面症状,特别是无情和脱离.
- 认知能力的改善没有得到复制,而COVID-19大流行中断可能影响了结果.
- 需要进一步的研究来阐明质的作用机制,并开发针对性治疗SRD的动机缺陷的向治疗方法.

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...
