Background: The nutritional status in patients with cirrhosis is not so easy to assess properly. Considering the relationship between brain-derived neurotrophic factor (BDNF) and energy homeostasis, the main aim of this study was to evaluate the concentration of BDNF in children and adolescents with cirrhosis due to biliary atresia (BA) and correlate it with their nutritional status. Methods: Fifty-three children and adolescents with cirrhosis due to BA and 33 healthy controls were enrolled in this study. Nutritional status was evaluated using anthropometric parameters, and serum BDNF was measured by ELISA. Spearman coefficient was used to evaluate the correlation between variables. Results: In the cirrhosis group, 28.8% were undernourished and in the control group, 100% were well-nourished. BDNF median values for the control and cirrhosis group were 28.5 and 9.0 pg/ml respectively. BDNF and platelets were positively associated with both Standard Deviation Score (SDS) for height-for-age ratio and SDS for triceps skinfold thickness-for-age ratio. Conclusions: Considering these associations, BDNF may be an indirect biomarker of nutritional status in children and adolescents with chronic liver disease. Further studies must be conducted to clarify the role of BDNF in this population.

Pediatric bipolar disorder (PBD) is a serious mental disorder that affects the development and emotional growth of affected patients. The brain derived neurotrophic factor (BDNF) is recognized as one of the possible markers of the framework and its evolution. Abnormalities in BDNF signaling in the hippocampus could explain the cognitive decline seen in patients with TB. Our aim with this study was to evaluate possible changes in hippocampal volume in children and adolescents with BD and associate them to serum BDNF. Subjects included 30 patients aged seven to seventeen years from the ProCAB (Program for Children and Adolescents with Bipolar Disorder). We observed mean right and left hippocampal volumes of 41910.55 and 41747.96 mm3, respectively. No statistically significant correlations between peripheral BDNF levels and hippocampal volumes were found. We believe that the lack of correlation observed in this study is due to the short time of evolution of BD in children and adolescents. Besides studies with larger sample sizes to confirm the present findings and longitudinal assessments, addressing brain development versus a control group and including drug-naive patients in different mood states may help clarify the role of BDNF in the brain changes consequent upon BD.

Background:Fibromyalgia (FM) is a common rheumatic disease characterized by chronic widespread pain, sleep and mood disorders. A higher prevalence of FM in women compared with men is well known, although the specific differences in clinical manifestations related to gender are still poorly defined. Brain-Derived Neurotrophic Factor (BDNF) is an endogenous growth factor that gained attention for its potential as biomarker of several diseases, including FM and depression.Objectives:The aims of this study were to investigate gender-related difference among males and females affected by FM in clinical manifestations, depressive features and BDNF serum level, evaluating also the diagnostic potential of the latter.Methods:We consecutively enrolled adult patients affected by FM (ACR 2016) referring to our out-patient clinic. Each subject underwent clinical and answered to questionnaires for the severity of FM symptoms (Revised Fibromyalgia Impact Questionnaire, R-FIQ) and depressive symptoms (Beck Depression Inventory-II, BDI-II). We collected blood samples from a subgroup of patients of both sexes, matched for age, for BDNF serum level dosage through ELISA. BDNF levels were assessed also in a control group, matched for sex and age.Results:The cohort was composed by 201 FM patients (172 F, 29 M), mean age 49.13. Females showed higher values of R-FIQ total score (p=0,0005) as well the specific items of the R-FIQ for pain (p=0,013), fatigue (p=0,014), memory problems (p=0,007), tenderness to touch (p<0,0001), balance problems (p<0,0001) and sensitivity to environmental stimuli (p=0,012) when compared with males (fig. 1). There was no difference in BDI-II between males and females, but notably male patients reported a significantly higher frequency of coexisting depressive disorder (p=0,038) (fig. 2). Serum BDNF levels were evaluated in 40 FM patients and 40 healthy controls (HC) (F:M 1:1). BDNF levels were significantly lower in FM patients compared with HC (p<0,0001). Among FM patients, BDNF levels were lower in males compared with females (p<0,0001) (fig.3). BDNF did not correlate with any clinical and clinimetric parameter. BDNF showed a good diagnostic performance (AUC=0,89, CI95%=0,82-0,9630, p<0,0001) (fig. 4). At a cut-off value <6,47 ng/dl, BDNF showed a specificity of 75% and a sensibility of 92,31%,(CI 95%=79,68-97.35) for FM identification (LR=3,692).Conclusion:FM clinical manifestations are strongly dependant from gender. While females present a more severe disease and a higher burden of symptoms, mood disorders tend to be a major characteristic of males with FM. Reduced BDNF serum levels have been reported as typical of depressive disorders. Our findings of lower BDNF levels in male FM patients compared to females support this hypothesis. BDNF have potential as biomarker of the disease and should be validated in larger cohorts.References:[1]Sarzi-Puttini et al. Nature Reviews 2020[2]Colucci-D’Amato et al.

The successful provision of optimal nutrition in children with serious diseases depends on the right diet, as well as the addition of specialized mixtures for its correction. The aim of the study was to study the effectiveness of supplemental nutrition in hereditary fermentopathy (cystic fibrosis) in children. The work included a three-year follow-up of 69 children aged 3 to 15 years suffering from cystic fibrosis. Patients were divided into two groups: 37 patients with cystic fibrosis group 1, receiving a modified version of treatment with additional enteral nutrition and 32 patients with cystic fibrosis group 2, receiving traditional treatment. The study conducted a comparative analysis of changes in trophic status in patients using nutritional support mixture produced in the Russian Federation – "Nutrien-standard"in diet therapy. Laboratory, functional and anthropometric parameters were monitored once a month. A significant increase in the physical development of patients was obtained only in the second year of use in the diet of supplementary nutrition, p<0.05. At the 3rd year of treatment, the results of positive dynamics of nutritional status in both groups were confirmed, while the increase in body mass index in the main group was 6.7%, and in the control group-only 1% (p<0.05). It is noted that the use of this mixture allows to achieve positive dynamics of nutritional status in 27% of patients and in 73% of cases to completely eliminate it. The obtained results prove the expediency of additional use of "Nutrient-standard" mixture in the complex therapy of patients with hereditary pancreatic enzyme deficiency, cystic fibrosis

Objective: The objective of the study was to evaluate the antidepressant activity of quercetin in monosodium glutamate (MSG) model of depressed male mice. Methods: MSG was administered (500 mg/kg) to different groups of albino male mice daily for 21 days to induce depression. The interventions (Quercetin and imipramine) were started on day 9th and continued till 21st day. On 23rd day, mice are sacrificed, hippocampus and amygdala supernatant are subjected for analysis. p<0.05 was considered as statistically significant. Results: There was a statistically significant reduction in interleukin (IL)-6 levels in animals treated with quercetin and imipramine compared to control group (p<0.001). There was also a statistically significant increase in brain-derived neurotrophic factor (BDNF) levels in quercetin with MSG groups (p<0.05) and imipramine with MSG groups (p<0.01). There was no statistically significant difference in IL-6 and BDNF levels between the groups of animals treated with quercetin (100 mg/kg) and imipramine (10 mg/kg) alone. Conclusion: Quercetin appeared to have an antidepressant activity. More extensive research is required to substantiate and elucidate the role of quercetin in behavioral disorders such as depression.

Serum Bdnf

Brain-derived neurotrophic factor (BDNF) helps restore neuronal function following mild traumatic brain injury. BDNF levels can be obtained in blood serum and more recently in saliva. However, the relationship between serum and salivary BDNF is poorly understood—especially in relation to alterations in BDNF levels following mild traumatic brain injury. In this study, serum and salivary BDNF were collected from a sample of 42 collegiate student athletes. Half of the participants were recently cleared by a physician and/or an athletic trainer to return-to-play after experiencing a sports-related concussion. The other half had not experienced a concussion within the past year and were matched by age, sex, sport, and time of sample. Results suggest that incidences of depression, anxiety, and stress were all elevated in the concussion group, relative to the control participants. When controlling for stress-related negative affect, serum BDNF was elevated in the concussion group. However, there was no difference in salivary BDNF. Serum and salivary BDNF were uncorrelated across the entire sample. Yet, these measures of BDNF were correlated in the concussion group, but not the control group. In sum, serum BDNF is elevated in concussion post return-to-play; however, further research is needed to explore the utility of salivary BDNF following concussion.

Objectives: This study aimed to investigate serum chemerin concentrations in obese children and adolescents and to investigate the associations of chemerin with body mass index (BMI), lipid levels, and insulin sensitivity. Methods: Forty-eight obese and 40 nonobese Chinese children and adolescents were included in the study. BMI and levels of chemerin, lipids, glucose, and insulin were measured following an overnight fast. The Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and BMI standard deviation score (BMI-SDS) were determined for all participants. Results: Serum chemerin levels were found to be significantly higher in obese children and adolescents than in control group members (94.83 ± 5.99 ng/mL vs 56.43 ± 4.16 ng/mL, P < .001). There were significant correlations between chemerin and age, BMI, BMI-SDS, total triglyceride (TG) levels, insulin levels, and HOMA-IR. After controlling for age, we found that chemerin levels were also significantly correlated with BMI-SDS (r =+ 0.284, P = .008) and HOMA-IR (r =+ 0.241, P = .034). In a stepwise multiple regression analysis, we observed only BMI-SDS to be an important determinant of chemerin level. Conclusions: In our sample of Chinese children and adolescents, chemerin levels were significantly higher in the obese group than in the control group. Chemerin levels were positively correlated with BMI-SDS and HOMA-IR and negatively correlated with age. We thus believe that further study is necessary to investigate the risk of metabolic abnormalities in young obese children and adolescents.

AIMS: To determine the effect of Mat Pilates on serum levels of interleukin-10 and brain-derived neurotrophic factor in women with multiple sclerosis.METHODS: Thirty women with multiple sclerosis with mild to moderate disability were recruited and randomly divided into equal Pilates training and Control groups. Patients in the training group accomplished a Pilates program three times a week for eight weeks. The Control group maintained their routine lifestyle. The serum level of interleukin-10 and brain-derived neurotrophic factor were measured before and after the protocol. The differences between groups were assessed by using analysis of covariance test to compare post-tests by considering covariate pre-tests (assuming a p-value <0.05 as significant).RESULTS: There were no significant changes in interleukin-10 (13.09±5.36 ng/ml in the Pilates training group compared to 13.21±4.76 ng/ml in the Control group, p= 0.81), whereas an increase in brain-derived neurotrophic factor was observed after eight-week Pilates training (11550.14±2619.60 ng/ml in the Pilates training group compared to 9664.35±3161.66 ng/ml in the Control group, p= 0.03).CONCLUSIONS: The results suggest that the intensity and duration of this protocol was not related to significant changes in interleukin-10, but was followed by an increase in brain-derived neurotrophic factor in these patients. Based on this finding, physical activity according to the individual’s ability is recommended for patients with multiple sclerosis, in parallel with drug therapy.

AbstractObjectiveMental disorders can have a major impact on brain development. Peripheral blood concentrations of brain-derived neurotrophic factor (BDNF) are lower in adult psychiatric disorders. Serum BDNF concentrations and BDNF genotype have been associated with cortical maturation in children and adolescents. In 2 large independent samples, this study tests associations between serum BDNF concentrations, brain structure, and psychopathology, and the effects of BDNF genotype on BDNF serum concentrations in late childhood and early adolescence.MethodsChildren and adolescents (7-14 years old) from 2 cities (n = 267 in Porto Alegre; n = 273 in São Paulo) were evaluated as part of the Brazilian high-risk cohort (HRC) study. Serum BDNF concentrations were quantified by sandwich ELISA. Genotyping was conducted from blood or saliva samples using the SNParray Infinium HumanCore Array BeadChip. Subcortical volumes and cortical thickness were quantified using FreeSurfer. The Development and Well-Being Behavior Assessment was used to identify the presence of a psychiatric disorder.ResultsSerum BDNF concentrations were not associated with subcortical volumes or with cortical thickness. Serum BDNF concentration did not differ between participants with and without mental disorders, or between Val homozygotes and Met carriers.ConclusionsNo evidence was found to support serum BDNF concentrations as a useful marker of developmental differences in brain and behavior in early life. Negative findings were replicated in 2 of the largest independent samples investigated to date.

OBJECTIVE AND METHOD: There is a growing amount of data indicating that alterations in brain-derived neurotrophic factor and increased oxidative stress may play a role in the pathophysiology of bipolar disorder. In light of recent evidence demonstrating that brain-derived neurotrophic factor levels are decreased in situations of increased oxidative stress, we have examined the correlation between serum thiobarbituric acid reactive substances, a measure of lipid peroxidation, and serum brain-derived neurotrophic factor levels in bipolar disorder patients during acute mania and in healthy controls. RESULTS: Serum thiobarbituric acid reactive substances and brain-derived neurotrophic factor levels were negatively correlated in bipolar disorder patients (r = -0.56; p = 0.001), whereas no significant correlation was observed in the control group.. CONCLUSION: These results suggest that alterations in oxidative status may be mechanistically associated with abnormal low levels of brain-derived neurotrophic factor observed in individuals with bipolar disorder.
