Cao J, Gorwood P, Ramoz N, Viltart O. The Role of Central and Peripheral Brain-Derived Neurotrophic Factor (BDNF) as a Biomarker of Anorexia Nervosa Reconceptualized as a Metabo-Psychiatric Disorder. Nutrients 2024; 16:2617. [PMID: 39203753 PMCID: PMC11357464 DOI: 10.3390/nu16162617] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2024] [Revised: 07/26/2024] [Accepted: 08/04/2024] [Indexed: 09/03/2024] Open
Abstract
Neurotrophic factors play pivotal roles in shaping brain development and function, with brain-derived neurotrophic factor (BDNF) emerging as a key regulator in various physiological processes. This review explores the intricate relationship between BDNF and anorexia nervosa (AN), a complex psychiatric disorder characterized by disordered eating behaviors and severe medical consequences. Beginning with an overview of BDNF's fundamental functions in neurodevelopment and synaptic plasticity, the review delves into recent clinical and preclinical evidence implicating BDNF in the pathophysiology of AN. Specifically, it examines the impact of BDNF polymorphisms, such as the Val66Met variant, on AN susceptibility, prognosis, and treatment response. Furthermore, the review discusses the interplay between BDNF and stress-related mood disorders, shedding light on the mechanisms underlying AN vulnerability to stress events. Additionally, it explores the involvement of BDNF in metabolic regulation, highlighting its potential implications for understanding the metabolic disturbances observed in AN. Through a comprehensive analysis of clinical data and animal studies, the review elucidates the nuanced role of BDNF in AN etiology and prognosis, emphasizing its potential as a diagnostic and prognostic biomarker. Finally, the review discusses limitations and future directions in BDNF research, underscoring the need for further investigations to elucidate the complex interplay between BDNF signaling and AN pathology.

Prog Neuropsychopharmacol Biol Psychiatry 2024; 131:110954. [PMID: 38286331 DOI: 10.1016/j.pnpbp.2024.110954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 01/07/2024] [Accepted: 01/24/2024] [Indexed: 01/31/2024]
Abstract
As an important neurotrophic factor in the central nervous system, Brain-derived Neurotrophic Factor (BDNF) has been implicated in the pathophysiology of psychiatric disorders in many studies. However, its value as a biomarker for the diagnosis and differential diagnosis of mental disorders is still controversial, and its change patterns among different mental disorders have not been compared. We conducted a network meta-analysis of BDNF levels in different psychiatric disorders including schizophrenia(SCZ), major depressive disorder(MDD), bipolar disorder(BD), panic disorder(PD), post-traumatic stress disorder(PTSD), obsessive-compulsive disorder(OCD), generalized anxiety disorder(GAD) and insomnia. Studies were identified by searching electronic databases through 31/05/2023. BDNF levels decreased in patients with BD, MDD, OCD, PD, SCZ compared with controls, while significantly increased in patients with PTSD. According to the network meta-analysis, BDNF levels were significantly decreased in MDD and SCZ compared with BD (-2.6, 95% CIs [-5.32 to -0.15] and - 2.68 95% CIs [-5.18 to -0.23] respectively). However, in the traditional meta-analysis, there was a trend towards lower BDNF levels in SCZ compared to BD, with no significant difference (SMD = -0.20, 95% CIs [-0.49 to 0.08]). In conclusion, abnormal BDNF levels have been found in psychiatric disorders, and the changes in peripheral BDNF levels in patients with psychiatric disorders were reconfirmed in this study, which suggests BDNF exhibits promising clinical utility and may hold diagnostic value in distinguishing between MDD and BD.

Abstract
Changes in cardiac autonomic nervous system (ANS) regulation observed in psychiatric disorders may be mitigated by antidepressants. We meta-analyzed and systematically reviewed studies examining antidepressants' effects on ANS outcomes, including heart rate variability (HRV). We conducted a PRISMA/MOOSE-compliant search of PubMed and Scopus until March 28th, 2022. We included randomized placebo-controlled trials (RCTs) and pre-post studies, regardless of diagnosis. We pooled results in random-effects meta-analyses, pooling homogeneous study designs and outcomes. We conducted sensitivity analyses and assessed quality of included studies. Thirty studies could be meta-analyzed. Selective serotonin reuptake inhibitors (SSRIs) were significantly associated with a reduction in the square root of the mean-squared difference between successive R-R intervals (RMSSD) (SMD= -0.48) and skin conductance response (SMD= -0.55) in RCTs and with a significant increase in RMSSD in pre-post studies (SMD=0.27). In pre-post studies, tricyclic antidepressants (TCAs) were associated with a significant decrease in several HRV outcomes while agomelatine was associated with a significant increase in high frequency power (SMD= 0.14). In conclusion, SSRIs reduce skin conductance response but have no or inconclusive effects on other ANS outcomes, depending on study design. TCAs reduce markers of parasympathetic function while agomelatine might have the opposite effect. Studies are needed to investigate the impact of SSRIs on the recovery of cardiac ANS regulation after acute myocardial infarction, and the effects of newer antidepressants.

[PMID: 36383269 DOI: 10.1007/s10620-022-07717-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Accepted: 10/03/2022] [Indexed: 11/18/2022]
Abstract
BACKGROUND Functional dyspepsia (FD) is characterized with multiple symptoms of indigestion and often accompanied with anxiety. However, there is currently an absence of effective treatment. Tandospirone is commonly used to treat generalized anxiety disorders. Whether tandospirone can improve the clinical symptoms of FD remain unknown. AIMS The present study was designed to explore the pharmacological effect of tandospirone on FD patient with anxiety, and the potential mechanisms were also elucidated. METHODS FD patients with anxiety were randomly divided into placebo and tandospirone treatment groups. Healthy volunteers were simultaneously recruited as control group. The gastrointestinal symptom score (GIS) and Hamilton anxiety scale (HAM-A) were performed before and after treatments with placebo or tandospirone. The serum levels of brain-derived neurotrophic factor (BDNF) and multiple inflammatory cytokines including tumor necrosis factor-α (TNF-α), and interleukin (IL)-6, IL-4, IL-1β, and IL-10 were determined. Regression analyses relating BDNF levels and gastrointestinal symptoms were performed. RESULTS Tandospirone significantly alleviated the gastrointestinal and anxiety symptoms of FD patient, as evidenced by reductions of GIS index and HAM-A scores. Compared with the healthy volunteers, FD patients had lower BDNF and IL-10 levels, but higher levels of IL-6 and TNF-α. Importantly, tandospirone increased serum BDNF and IL-10 and decreased IL-6 levels in FD patients. Relative analysis revealed that BDNF level was negatively associated with gastrointestinal symptoms in FD patients. CONCLUSION Tandospirone effectively improved both anxiety and gastrointestinal symptoms of patients with FD, and these therapeutic effects may be associated with the modulation of BDNF and inflammatory cytokines.

The Effect of Humanistic Care Combined with Predictive Nursing on Negative Emotions and Incidence of Cardiovascular Events in Hemodialysis Patients. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:7562525. [PMID: 35529264 PMCID: PMC9076300 DOI: 10.1155/2022/7562525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 03/22/2022] [Accepted: 03/30/2022] [Indexed: 11/22/2022]
Abstract
Objective To explore the effect of humanistic care combined with predictive nursing on the negative emotions and incidence of cardiovascular events in hemodialysis patients. Methods A total of 90 patients undergoing hemodialysis in our hospital from December 2020 to September 2021 were selected as the research subjects and divided into the study group (n = 45) and the control group (n = 45) by the random number table method. The patients in the control group were given routine nursing, and the patients in the study group were given humanistic care combined with predictive nursing. The effects between the two groups were compared. Results After nursing, cardiac troponin I (cTn I) level, Hamilton Depression Scale (HAMD) scores, and Hamilton Anxiety Scale (HAMA) scores in the two groups decreased, and the scores were lower in the study group than the control group (P < 0.05). The World Health Organization on Quality of Life Brief Scale (WHOQOL-BREF) scores in both groups increased and were higher in the study group than the control group (P < 0.05). The nursing satisfaction in the study group was higher than that in the control group, and the incidence of cardiovascular adverse events in the study group was lower than that in the control group (P < 0.05). Conclusion In the process of hemodialysis, the application of humanistic care combined with predictive nursing to hemodialysis patients can significantly decrease the cTn I level, reduce the negative emotions of patients, improve the quality of life and nursing satisfaction of patients, and reduce the occurrence of adverse cardiovascular events.

Abstract
Traditionally, yoga has been used as a means for spiritual growth but over the past two decades or so its therapeutic benefits in psychiatric disorders have been scientifically explored. Yoga has been shown to be useful as a mono-therapy in mild to moderate depression and as an adjuvant in several psychiatric disorders including schizophrenia, anxiety disorders, substance use disorders and Mild Cognitive Impairment. Furthermore, systematic attempts have been made to understand the biological correlates of yoga in these psychiatric disorders. Given that no psychiatric disorder has strong and established biomarkers, it is interesting that preliminary research has demonstrated significant changes in certain important biomarkers following regular yoga practice. In this brief review, we provide an update on the effects of yoga on biochemical, neuro-physiological and neuro-imaging related bio-markers in psychiatric disorders. Although findings and trends are promising, much more research is warranted to establish a definite biological basis for yoga in psychiatry.
