Choi SH, Choi-Kwon S, Kim MS, Kim JS. Poor nutrition and alcohol consumption are related to high serum homocysteine level at post-stroke. Nutr Res Pract 2015; 9:503-10. [PMID: 26425280 PMCID: PMC4575963 DOI: 10.4162/nrp.2015.9.5.503] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2015] [Revised: 06/30/2015] [Accepted: 06/30/2015] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND/OBJECTIVES Increased serum homocysteine (Hcy) levels have been reported to be related to the occurrence of cardio- and cerebrovascular diseases. High serum Hcy levels are also related to the development of secondary stroke and all-cause mortality. The purpose of this study was to investigate the prevalence of high serum homocysteine level and relating factors, and the change over the 10 month period post-stroke. SUBJECTS/METHODS Consecutive stroke patients who were admitted to the Asan Medical Center were enrolled. Ten months after the onset of stroke, an interview with a structured questionnaire was performed and blood samples were obtained for the biochemical parameters. Nutritional status was determined using the mini nutritional assessment (MNA) score and dietary nutrient intakes were also obtained using a 24 hour recall method. RESULTS Out of 203 patients, 84% were malnourished or at risk of malnutrition, and 26% had high homocysteine levels at 10 months post-stroke. Using logistic regression, the factors related with high homocysteine levels at 10 months post-stroke included heavy alcohol consumption (P = 0.020), low MNA scores (P = 0.026), low serum vitamin B12 (P = 0.021) and low serum folate levels (P = 0.003). Of the 156 patients who had normal homocysteine levels at admission, 36 patients developed hyperhomocysteinemia 10 months post-stroke, which was related to heavy alcohol consumption (P = 0.013). Persistent hyperhomocysteinemia, observed in 22 patients (11%), was related to male sex (P = 0.031), old age (P = 0.042), low vitamin B6 intake (P = 0.029), and heavy alcohol consumption (P = 0.013). CONCLUSION Hyperhomocysteinemia is common in post-stroke, and is related to malnutrition, heavy alcohol drinking and low serum level of folate and vitamin B12. Strategies to prevent or manage high homocysteine levels should consider these factors.

Abstract
Elevated plasma homocysteine levels have been found in different psychiatric disorders, including major depression and eating disorders. The aim of the present study was to evaluate whether presence of depression or depressive symptoms is associated with elevated homocysteine levels in patients with eating disorders. Total plasma homocysteine levels were assessed in 44 females with anorexia nervosa (n = 21) or bulimia nervosa (n = 23). Comorbid major depressive disorder (MDD) was diagnosed according to DSM-IV criteria using a semi-structured interview (SCID-I). Furthermore, depressive symptoms were assessed using Beck's depression inventory (BDI). Presence of MDD was not associated with elevated homocysteine levels (t-test: T = 0.42; df = 42; P = 0.68). However, self-rated presence of clinically relevant depressive symptoms (BDI score18) was associated with elevated homocysteine (T = -2.8; df = 42; P = 0.008). Presence of depressive symptoms may explain elevated homocysteine levels previously reported in patients with eating disorders or vice versa. Longitudinal studies are needed to unravel this hen or egg problem.

Abstract
AIMS The typology by Lesch distinguishes between four subtypes: type 1 (model of allergy), type 2 (model of anxiety or conflict), type 3 (alcohol as an antidepressant), and type 4 (alcohol as adaptation). Taking into account that alcohol dependence is associated with elevated homocysteine levels, this study was undertaken to investigate different MTHFR (methylenetetrahydrofolate reductase) genotypes related to homocysteine metabolism in patients with alcohol dependence who were classified according to Lesch's typology (LT). SUBJECTS AND METHODS 134 non-abstinent chronic alcoholics (112 males, 22 females; mean age 44.2 (SD 8.9) years) were classified according to LT and divided into four groups: LT 1 (n = 26), LT 2 (n = 65), LT 3 (n = 58), and LT 4 (n = 18). Total plasma homocysteine levels and MTHFR genotypes -393, 677, and 1,793 were determined. RESULTS We observed a significantly higher frequency of the thermolabile MTHFR 677 C-->T variant (TT) in patients classified as subtype LT4 when compared with subtypes LT2 and LT3 (P = 0.005). Furthermore, for the MTHFR -393 C --> A-polymorphism, significantly more AC/AA variants were found in subtype LT4 (P = 0.034). No differences in allele-distribution were detected for MTHFR 1793. CONCLUSION To our knowledge, this is the first study evaluating MTHFR genotypes in patients who were classified according to LT. Significantly different distributions of MTHFR 677 and -393 variants within Lesch Type 4 as compared with Types 2 and 3 hint at genetic determination of Lesch subtypes.

Abstract
AIMS It has been suggested that elevated total plasma homocysteine levels might be useful to predict alcohol withdrawal seizures. The typology by Lesch distinguishes between four subtypes of which type 1 suffers from marked withdrawal symptoms, including alcohol withdrawal seizures. This study was undertaken to investigate total plasma homocysteine levels in actively drinking patients with alcoholism who were classified according to Lesch's typology. SUBJECTS AND METHODS We determined total plasma homocysteine levels in 144 non-abstinent chronic alcoholics (115 men, 29 women; aged 22-67 years). Patients were classified in Lesch's typology (LT) and were divided into two groups: LT 1 (n = 27) and LT 2-4 (n = 117). Within the groups, patients with or without a history of alcohol withdrawal seizures were differentiated. RESULTS All patients with a history of alcohol withdrawal seizures had significantly elevated plasma homocysteine concentrations at admission when compared with those without seizures (Mann-Whitney U, P < 0.001). Furthermore, patients classified as LT 1 who suffered from an alcohol withdrawal seizure (n = 12) had significantly higher plasma homocysteine levels (Z = -2.31, P = 0.02) when compared to the corresponding types 2-4 (n = 24). Using a logistic regression analysis, withdrawal seizures were best predicted by a high homocysteine level at admission but even more pronounced in LT 1 (Wald's chi-squared [chi(2)] = 10.7; odds ratio [OR] 1.24; 95% confidence interval [CI] 1.03-1.51; P < 0.001) when compared with LT 2-4 (chi(2) = 10.6; OR 1.06; 95%CI 1.03-1.14; P = 0.004). CONCLUSION To our knowledge, this is the first study evaluating homocysteine levels in patients who were classified according to Lesch's typology. Homocysteine levels on admission may be a useful screening method to identify actively drinking patients at risk of alcohol withdrawal seizures, especially in alcoholics with Lesch type 1.

Abstract
There is evidence from in vitro and in vivo studies that homocysteine induces neuronal damage and cell loss by both excitotoxicity and different apoptotic processes. Clinical evidence suggest a strong relationship between higher plasma homocysteine levels and brain atrophy in healthy elderly subjects as well as in elderly at risk of and with Alzheimer's disease. Chronic alcoholism leads to elevated plasma homocysteine levels, as shown by clinical investigations and animal experiments. In addition, an association between brain atrophy and increased levels of homocysteine in chronic alcoholism was shown. This may have important implications for the pathogenesis of alcoholism-associated brain atrophy. Furthermore, taking into account that high plasma homocysteine levels are helpful in the prediction of alcohol withdrawal seizures, early anticonvulsive therapy could prevent this severe complication. Homocysteine plays a role in a shared biochemical cascade involving overstimulation of N-methyl-D-aspartate (NMDA) receptors, oxidative stress, activation of caspases, DNA damage, endoplasmic reticulum and mitochondrial dysfunction. These mechanisms are believed to be important in the pathogenesis of both excitotoxicity and apoptotic neurotoxicity. Prospective intervention studies may show whether the incidence of complications of alcohol withdrawal or alcoholism-associated disorders can be reduced by therapeutic measures with early lowering of elevated homocysteine levels (e.g. folate administration). The most important pathophysiological and pathobiochemical features of glutamatergic neurotransmission and of ethanol-induced hyperhomocysteinaemia are reviewed in relation to their excitotoxic and apoptotic potential.

Abstract
O autor apresenta uma visão geral da literatura atual sobre homocisteína como um fator de risco para os transtornos neuropsiquiátricos. Foram pesquisados os bancos de dados MEDLINE, Current Contents e EMBASE (entre 1966 e 2002) para publicações em língua inglesa utilizando as palavras-chave ''Homocisteína'' e ''AVC''; ''Doença de Alzheimer''; ''Déficit Cognitivo'', ''Epilepsia'', ''Depressão'' ou ''Doença de Parkinson''. Artigos individuais foram pesquisados para referências cruzadas relevantes. É biologicamente plausível que altos níveis de homocisteína possam causar lesão cerebral e transtornos neuropsiquiátricos. A homocisteína é pró-aterogênica e pró-trombótica. Dessa forma, aumenta o risco de acidente vascular cerebral, podendo ter um efeito neurotóxico direto. Evidências de que a homocisteína seja um fator de risco para doença microvascular cerebral são conflitantes, mas justificam maiores estudos. Estudos transversais e alguns longitudinais suportam a crescente prevalência de acidente vascular cerebral e demência vascular em indivíduos com hiper-homocisteinemia. As evidências de crescente neurodegeneração estão se acumulando. A relação com a depressão ainda é experimental, da mesma forma como com a epilepsia. Atualmente, estudos sobre tratamentos são necessários para colocar as evidências sobre bases mais sólidas. Os pacientes de alto risco também devem ser pesquisados para hiper-homocisteínemia, cujo tratamento deve ser feito com ácido fólico. Mais evidências são necessárias antes que pesquisas populacionais possam ser recomendadas.

Abstract
Chronic alcohol consumption can induce brain atrophy, whereby the exact mechanism of brain damage in alcoholics remains unknown. There is evidence that chronic alcoholism is associated with hyperhomocysteinemia. Homocysteine is an excitatory amino acid which markedly enhances the vulnerability of neuronal cells to excitotoxic and oxidative injury in vitro and in vivo. The present volumetric magnetic resonance imaging study included 52 chronic alcoholics and 30 non-drinking healthy controls. Patients were active drinkers and had an established diagnosis of alcohol dependence. We investigated the influence of different variables on the hippocampal volume of patients suffering from chronic alcoholism. We observed that pathological raised levels of plasma homocysteine showed the most significant correlation to hippocampal volume reduction (P<0.001, multiple regression analysis). Raised plasma levels of homocysteine are associated with hippocampal (brain) atrophy in alcoholism.

Abstract
Recently, it has been suggested that alcohol-induced hyperhomocysteinaemia in patients suffering from chronic alcoholism might be a risk factor for alcohol withdrawal seizures. In the present follow-up study 12 patients with chronic alcoholism who suffered from withdrawal seizures had significantly higher levels of homocysteine (Hcy) on admission (71.43 +/- 25.84 mol/l) than patients (n = 37) who did not develop seizures (32.60 +/- 24.87 mol/l; U = 37.50, p = 0.0003). Using a logistic regression analysis, withdrawal seizures were best predicted by a high Hcy level on admission (p < 0.01; odds ratio 2.07). Based on these findings we developed an artificial neural network system (Kohonen feature map, KFM) for an improved prediction of the risk of alcohol withdrawal seizures. Forty-nine patients with chronic alcoholism (12 with alcohol withdrawal seizures and 37 without seizures) were randomized into a training set and a test set. Best results for sensitivity of the KFM was 83.3% (five of six seizure patients were predicted correctly) with a specificity of 94.4% (one false positive prediction of 19 patients). We conclude that in patients with alcohol-induced hyperhomocysteinaemia the KFM is a useful tool to predict alcohol withdrawal seizures.

Abstract
Chronic alcohol consumption can induce alterations in the function and morphology of most if not all brain systems and structures. However, the exact mechanism of brain damage in alcoholics remains unknown. Partial recovery of brain function with abstinence suggests that a proportion of the deficits must be functional in origin (i.e. plastic changes of nerve cells) while neuronal loss from selected brain regions indicates permanent and irreversible damage. There is growing evidence that chronic alcoholism is associated with a derangement in the sulfur amino acid metabolism. Recently, it has been shown that excitatory amino acid (EAA) neurotransmitters and homocysteine levels are elevated in patients who underwent withdrawal from alcohol. Furthermore, it has been found that homocysteine induces neuronal cell damage by stimulating NMDA receptors as well as by producing free radicals. Homocysteine neurotoxicity via overstimulation of N-methyl-D-aspartate receptors may contribute to the pathogenesis of both brain shrinkage and withdrawal seizures linked to alcoholism.

Abstract
The exact mechanism of brain atrophy in patients with chronic alcoholism remains unknown. There is growing evidence that chronic alcoholism is associated with oxidative stress and with a derangement in sulphur amino acid metabolism (e.g. ethanol-induced hyperhomocysteinemia). Furthermore, it has been reported that homocysteine induces neuronal cell death by stimulating N-methyl-D-aspartate receptors as well as by producing free radicals. To further evaluate this latter hypothesis we analysed serum levels of both homocysteine and markers of oxidative stress (malondialdehyde) in alcoholic patients who underwent withdrawal from alcohol. Homocysteine and malondialdehyde were quantified by high performance liquid chromatography (HPLC) in serum samples of 35 patients (active drinkers). There was a significant correlation (P<0. 01) between blood alcohol concentration and elevated homocysteine (Spearman's r=0.71) and malondialdehyde (r=0.90) levels on admission. In addition, homocysteine and malondialdehyde levels were found to be significant decreased after 3 days of withdrawal treatment (Wilcoxon test: homocysteine, Z=-5.127; malondialdehyde, Z=-3.120; P<0.01). We postulate that excitatory neurotransmitters and mechanisms of oxidative stress in patients with chronic alcoholism may partly mediate excitotoxic neuronal damage and hereby cause brain shrinkage.
