Vitamin B12, Folate, Homocysteine, Inflammatory Mediators (Interleukin-6, Tumor Necrosis Factor-α and C-Reactive Protein) Levels in Adolescents with Anxiety or Depressive Symptoms. Neuropsychiatr Dis Treat 2023; 19:785-800. [PMID: 37056916 PMCID: PMC10089149 DOI: 10.2147/ndt.s399378] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Accepted: 03/15/2023] [Indexed: 04/15/2023] Open
Abstract
Purpose To evaluate the prevalence of abnormal vitamin B12, folate, total homocysteine (tHcy), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP) levels, to analyze the relationship between these parameters and the severity of anxiety or depressive symptoms, and to explore the possible factors associated with abnormal levels of these parameters in adolescents with anxiety or depressive symptoms. Methods Adolescent (aged 12-18 years) outpatients with anxiety or depressive symptoms were recruited. The patient health questionnaire-9 and generalized anxiety disorder scale-7 were used to measure the severity of depression and anxiety. Serum vitamin B12, folate, tHcy, IL-6, TNF-α, and CRP levels were determined. Results 128 subjects were recruited. The prevalence of vitamin B12 and folate deficiency, tHcy, TNF-α, IL-6, and CRP elevation was 8.6%, 10.2%, 25.8%, 14.8%, 21.9%, and 10.2%, respectively, in adolescents with anxiety or depressive symptoms. Lower vitamin B12 levels were correlated with a higher risk of severe anxiety and depressive symptoms. The severity of some symptoms of anxiety or depression were weakly correlated with vitamin B12, folate, tHcy, IL-6, and CRP levels. Vitamin B12, folate, and tHcy levels were not associated with inflammatory mediators. Vitamin B12 deficiency was associated with older age and higher tHcy levels. Folate deficiency was associated with elevated tHcy. Elevated tHcy was associated with lower vitamin B12 and folate levels. IL-6 elevation was associated with elevated CRP and TNF-α. CRP elevation was associated with older age, higher BMI, and current drinking. Conclusion Lower vitamin B12 levels were correlated with a higher risk of severe anxiety or depressive symptoms. Weak correlations were observed between the severity of some symptoms of anxiety or depression and vitamin B12, folate, tHcy, IL-6, and CRP levels. Vitamin B12, folate, and tHcy levels were related to each other. IL-6 elevation was associated with elevated CRP and TNF-α. CRP elevation was associated with older age, higher BMI, and current drinking.

The Presence of Hyperhomocysteinemia Does Not Aggravate the Cardiometabolic Risk Imposed by Hyperuricemia in Young Individuals: A Retrospective Analysis of a Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:13521. [PMID: 36294101 PMCID: PMC9602869 DOI: 10.3390/ijerph192013521] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 10/10/2022] [Accepted: 10/15/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND Little research has been conducted into the effects of the combined manifestation of hyperuricemia and hyperhomocysteinemia on cardiometabolic risk factors and markers in young subjects. METHODS 1298 males and 1402 females, 14-to-20-year-olds, were classified into four groups: 1/normouricemic/normohomocysteinemic, 2/normouricemic/hyperhormohomocysteinemic, 3/hyperuricemic/normohomocysteinemic, and 4/hyperuricemic/hyperhomocysteinemic. Anthropometric measures, blood pressure, plasma glucose, insulin, lipids, markers of renal function, C-reactive protein, asymmetric dimethylarginine, and blood counts were determined. RESULTS Hyperuricemic males (but not females) had higher odds for hyperhomocysteinemia than normouricemic ones (OR: 1.8; 95% CI: 1.4-2.3; p < 0.001). Homocysteine and uric acid levels correlated directly (males: r = 0.076, females: r = 0.120; p < 0.01, both). Two-factor analysis of variance did not reveal a significant impact of hyperhomocysteinemia on any of the investigated cardiometabolic variables in females; in males, hyperuricemia and hyperhomocysteinemia showed a synergic effect on asymmetric dimethylarginine levels. Among four groups, subjects concurrently manifesting hyperuricemia and hyperhomocysteinemia did not presented the highest continuous metabolic syndrome score-a proxy measure of cardiometabolic risk; neither the multivariate regression model indicated a concurrent significant effect of uric acid and homocysteine on continuous metabolic syndrome score in either sex. CONCLUSION In young healthy subjects, hyperhomocysteinemia does not aggravate the negative health effects imposed by hyperuricemia.

Abstract
OBJECTIVE To characterize the clinical features of isolated elevated plasma homocysteine (eHcy)-induced peripheral neuropathy (IHIN) in adults. METHODS Charts of subjects with the diagnosis of IHIN who visited neuromuscular clinic from January 01, 2012 to September 30, 2014 were reviewed. Subjects with identifiable etiologies for neuropathy, such as B12/folate deficiency; metabolic, toxic, endocrinologic, infectious/inflammatory renal or liver diseases; or traumatic nerve injury, were excluded. Their clinical presentations were recorded and analyzed. RESULTS Thirty subjects (age: 63.2 ± 14.8 years, 13 males) were included. They all had an isolated increased homocysteine level (15.4 ± 5.3 μmol/L) but normal levels of B12, folate, and methylmalonic acid. Of 30, 14 (46.7%) had numb feet, 11 (36.7%) had numb hands, 7 (23.3%) had pain in lower extremities, and 10 (33.3%) had tingling in feet. Distal sensory deficits were present in 18/30 (60%) patients. Distal limb weakness was seen in 4 and decreased tendon reflexes in 12 patients. CONCLUSIONS Sensory deficits are predominant components of IHIN. Characterizing clinical features of IHIN would help better understand eHcy-related neuropathy and improve its management.

Abstract
Cardiovascular disease (CVD) is a major cause of mortality in type 1 diabetes mellitus (T1D). However, evidence of its risks and management is often extrapolated from studies in type 2 diabetic (T2D) patients or the general population. This approach is unsatisfactory given that the underlying pathology, demographics and natural history of the disease differ between T1D and T2D. Furthermore, with a rising life expectancy, a greater number of T1D patients are exposed to the cardiovascular (CV) risk factors associated with an ageing population. The aim of this review is to examine the existing literature around CVD in T1D. We pay particular attention to CVD prevalence, how well we manage risk, potential biomarkers, and whether the studies included the older aged patients (defined as aged over 65). We also discuss approaches to the management of CV risk in the older aged. The available data suggest a significant CVD burden in patients with T1D and poor management of CV risk factors. This is underpinned by a poor evidence base for therapeutic management of CV risk specifically for patients with T1D, and in the most relevant population - the older aged patients. We would suggest that important areas remain to be addressed, particularly exploring the risks and benefits of therapeutic approaches to CVD management in the older aged.

Abstract
This study was aimed at investigating the effects of quercetin on mRNA expression and activity of critical enzymes in homocysteine metabolism in rats fed a methionine-enriched diet. Rats were fed for 6 weeks the following diets, that is, control, 0.5% quercetin, 1.0% methionine, and 1.0% methionine plus 0.5% quercetin diets. Serum homocysteine was significantly increased after methionine treatment and decreased after the addition of quercetin. The mRNA expression of methionine synthase was significantly increased after methionine or methionine plus quercetin supplementation, while its enzymatic activity was significantly increased after methionine plus quercetin supplementation. The mRNA expression and enzymatic activity of cystathionine β-synthase and cystathionine γ-lyase were upregulated after quercetin, methionine, or quercetin plus methionine treatment and a more significant increase was observed for hepatic cystathionine β-synthase in the methionine plus quercetin treated rats, suggesting an interaction between methionine and quercetin. Meanwhile, hepatic ratio of S-adenosylmethionine to S-adenosylhomocysteine was significantly decreased in response to methionine supplementation and normalized after the addition of quercetin. It is concluded that quercetin reduces serum homocysteine by increasing remethylation and transsulfuration of homocysteine in rats exposed to a methionine-enriched diet.

Abstract
AIM The relationship between the methylenetetrahydrofolate reductase (MTHFR) A1298C polymorphism and the susceptibility of diabetes remains inclusive or controversial. For better understanding of the influence of MTHFR A1298C polymorphism on diabetes risk, we performed this meta-analysis. METHODS All related articles were identified through a search of PubMed, Embase, Chinese Biomedical Literature Database (CBM, Chinese), China National Knowledge Infrastructure (CNKI), and Wangfang Database (Chinese). The relationship between the MTHFR A1298C polymorphism and diabetes susceptibility was conducted by odds ratios (ORs) and 95% confidence intervals. RESULTS Total of six studies with 897 cases and 852 controls were included in our meta-analysis. Overall, the significance associated was found between MTHFR A1298C polymorphism and the susceptibility of diabetes under recessive model (CC vs. AC/AA OR=1.70, 95% CI=1.18-2.45, p=0.004). On the subgroup analysis according to ethnicity, the results indicated that MTHFR A1298C polymorphism has a significant association with diabetes in Asian population under dominant model (CC/AC vs. AA: OR=1.31, 95% CI=1.003-1.72, p=0.047). However, there was no association found between MTHFR A1298C polymorphism and diabetes susceptibility in Caucasians. CONCLUSIONS The results indicated that the MTHFR A1298C polymorphism is a dangerous factor for diabetes, especially for Asians.

Abstract
Cardiovascular diseases (CVDs) remain the main cause of morbidity and mortality around the world. A common polymorphism c.677C>T has been identified in the gene coding for methylenetetrahydrofolate reductase (MTHFR), which is involved in the remethylation of homocysteine, and may predispose to CVDs. A meta-analysis was performed to estimate the risk of CVDs associated with MTHFR c.677C>T in Turkish population. Published studies were retrieved from PubMed, Science Citation Index/Expanded, Google Scholar, Turkish Medline, and the Turkish Council of Higher Education Theses Database. For each study, we calculated odds ratios and 95 % confidence intervals (CI), assuming frequency of allele and homozygote comparison, dominant and recessive genetic models. Thirty-one separate studies were included and 2.780 cases/3.022 controls were involved in the current meta-analysis. Significant association was found between c.677C>T polymorphism and risk of CVD when all studies pooled with random-effects model for T versus C (OR 1.33; 95 % CI 1.11-1.59; p = 0.002), TT vs. CC (OR 1.87; 95 % CI 1.35-2.60; p = 3.53E-04), TT+CT vs. CC (OR 1.32; 95 % CI 1.06-1.64; p = 0.014) and TT vs. CT+CC (OR 1.75; 95 % CI 1.29-2.37; p = 6.57E-04). Further analysis indicated the significant association between methylenetetrahydrofolate reductase (MTHFR) TT genotype and groups with venous thrombosis, peripheral arterial thrombosis, acute MI/MI. No publication bias was observed in any comparison model. Our results of meta-analysis suggest that MTHFR c.677C>T polymorphism is associated with the CVDs in Turkish population.

Serum asymmetric dimethylarginine (ADMA), homocysteine, vitamin B(12), folate levels, and lipid profiles in epileptic children treated with valproic acid. Eur J Pediatr 2011; 170:873-7.

Abstract
Recent reports have demonstrated elevated serum homocysteine (Hcy) levels in children receiving valproic acid (VPA) therapy. Elevated Hcy levels might play a potential role in the resistance to antiepileptic drugs, and might lead to an increased risk for a vascular disease. It has been reported that elevated total homocysteine (tHcy) levels are associated with elevated asymmetric dimethylarginine (ADMA) levels, which are factors that may be better indicators of endothelial dysfunction compared to serum homocysteine levels, because they are less sensitive to changes, such as fasting status, physical activity, and other factors. In this study, we aim to evaluate serum ADMA, Hcy, lipid, folate, and vitamin B₁₂ levels in epileptic children, receiving VPA monotherapy. Forty-four epileptic children, receiving VPA monotherapy for at least 6 months and 28 healthy children aged between 4 and 16 years, were recruited. Serum lipids, lipoproteins, folate, vitamin B₁₂, Hcy, and ADMA levels were analyzed in both study groups. Serum Hcy, ADMA, and vitamin B₁₂ levels were higher in patients than in controls (p < 0.001 for tHcy and ADMA levels; p < 0.05 for vitamin B₁₂ levels); however, serum lipid, lipoprotein, and folate levels were similar. According to the duration of epilepsy, serum tHcy, ADMA, and triglyceride (TG) levels were higher in patients with epilepsy for ≥ 2 years than in patients with epilepsy for < 2 years (p < 0.001 for serum ADMA levels, p < 0.01 for tHcy levels, and p < 0.05 for serum TG levels). Similarly, with respect to the duration of VPA therapy, serum tHcy, ADMA, and TG levels were higher in patients who had received VPA therapy for more than 2 years (p < 0.001 for serum ADMA levels, p < 0.05 for serum tHcy levels, p < 0.01 for TG levels). Serum ADMA levels were significantly higher in patients receiving VPA at the dose of 25-30 mg/kg/day than in those receiving 20 mg/kg/day (p < 0.01). In conclusion, our study found increased serum ADMA levels and increased tHcy levels in epileptic children receiving VPA monotherapy. Increased serum ADMA levels were demonstrated in epileptic children who have had a seizure history greater than 2 years, and have used VPA therapy for more than 2 years, and have received higher doses of VPA. Routine monitoring of serum ADMA and tHcy levels might have beneficial effects for patients receiving long-term VPA therapy, especially in children who have other potential risk factors for vascular diseases. Further studies are needed to investigate serum ADMA and Hcy levels, and the presence of vascular disease, as well as the potential interactions between serum ADMA levels and seizure control.

Abstract
OBJECTIVE The objective of this study was to investigate the regulatory effect of fish oil rich in omega-3 polyunsaturated fatty acids (PUFAs) on critical enzyme activity and mRNA expression involved in homocysteine (Hcy) metabolism. METHODS Thirty-six male Sprague-Dawley rats aged 3 wk, weighing 120 +/- 10 g, were randomly divided into three groups: the olive oil (OO) group, the tuna oil (TO) group, and the salmon oil (SO) group. The oil was orally administered every day using a stomach tube. Eight weeks later, plasma Hcy, phospholipids, omega-3 PUFAs, enzyme activity, and mRNA expression in tissues were determined. RESULTS Compared with the control group, phospholipids, total omega-3 PUFAs, and omega-3/omega-6 PUFAs in the liver and lung were significantly elevated in the TO and SO groups; 22:6omega-3 in the liver and lung was significantly increased in the TO group; and 20:5omega-3 in the two tissues was significantly elevated in the SO group. The level of plasma Hcy was significantly decreased with TO; methionine adenosyl transferase (MAT) activity was significantly increased and MAT mRNA expression was significantly upregulated with TO; cystathionine-gamma-lyase mRNA expression in TO was significantly upregulated; however, cystathionine beta-synthase and S-adenosylhomocysteine hydrolases were not significantly changed when compared with control. CONCLUSION TO rich in 22:6omega-3 decreases the concentration of Hcy despite increasing MAT activity and upregulating MAT mRNA expression through compensatory cystathionine-gamma-lyase mRNA expression, both of which are involved in Hcy metabolism.
