Tavani A, Bertuzzi M, Negri E, Loredana S, La Vecchia C. Alcohol, smoking, coffee and risk of non-fatal myocardial infarction in Italy. A food frequency questionnaire was used to assess the intake of caffeinated coffee. Six human cytochrome P450s expressed in HepG2 cells using vaccinia virus cDNA-directed expression, were used to study the biotransformation of caffeine and its metabolites. If validated, these data suggest that CYP1A2 polymorphisms may produce important clinical consequences. Coffee consumption and serum lipids: a meta-analysis of randomized controlled clinical trials. For consumption of caffeine-containing coffee alone, the relative risk estimates for 5-6 cups, 7-9 cups, and 10 or more cups per day relative to less than 1 cup per day were 1.4 (95% confidence interval (CI) 0.8-2.5), 2.1 (95% CI 0.9-4.9), and 2.5 (95% CI 1.0-6.5), respectively. The investigators followed 114 overweight and obese subjects from a weight loss clinic in a 2-stage process. Nevertheless, more nonsmokers than smokers had the highest enzyme indexes, suggesting that dietary elements or other factors may determine P-450IA2 activities in populations. Whether CYP1A2 … CYP1A2 and cardiovascular health. It is likely that these polymorphisms in the CYP1A2 gene will modulate the Coffee consumption was associated with a lower risk of CHD. Psychiatric morbidity was assessed with the General Health Questionnaire (GHQ-28) and defined by a score>6. ... 10 In contrast to these health-promoting effects, coffee also has harmful effects, such as increasing blood pressure 10 and the risk of myocardial infarction. J-shaped or U-shaped dose-response graphs of coffee consumption and CVD parameters partially explain the inconsistency of conclusions between coffee studies on CVD, highlighting a moderate intake of coffee. We prospectively investigated the impact of each beverage and their combination on mortality among Japanese patients with type 2 diabetes. Associations between coffee drinking and increased risk of myocardial infarction(15), hypertension(16,17) and IFG(18) have been observed in individuals who are carriers of the ‘slow’ C allele but not in those with the ‘fast’ AA genotype. The beneficial effects of adenosine during ischemia/reperfusion processes do not seem simple. Coffee is a major source of caffeine, which is metabolized by the polymorphic cytochrome P450 1A2 (CYP1A2) enzyme. After stratification by rs17321515 genotypes, coffee drinking remained significantly associated with a lower risk of CHD only among participants with GG genotype (OR, 0.62; 95% CI, 0.45–0.85). The OR (95% CI) was 1.01 (0.72–0.99). Spiller MA. DNA was available from 4369 participants (2113 cases and 2256 controls). with hypertension and myocardial infarction (MI) are different between slow and rapid metabolizers as defined by CYP1A2 genotype with adjustment for confounding factors. A similar effect of age was observed by Palmer et al,7 who found a greater risk of MI with caffeinated coffee consumption among women 45 through 59 years of age but not among women 60 years or older. http://jama.ama-assn.org/cgi/content/full/295/10/1135. Odds ratios (ORs) and Wald 95% confidence intervals (95% CIs) were estimated by conditional logistic regression to determine the effect of coffee intake on the risk of MI, with the lowest level of coffee intake (<1 cup/d) as the reference group. Several of the studies had varying range of outcomes with some showing very strong correlation and others weak. After adjustment for matching criteria and socioeconomic status, the OR for AMI was 2.9 (1.8-4.9) for ever hospitalized for depression. Additionally, after the 24-week diet and 18-month follow up the low-GI nutrigenetic diet group had significantly greater (p < 0.0001) improvements in total cholesterol (ketogenic - 35.4 ± 32.2 mg/dl; low-GI nutrigenetic - 52.5 ± 24.3 mg/dl), HDL cholesterol (ketogenic + 4.7 ± 4.5 mg/dl; low-GI nutrigenetic + 11.9 ± 4.1 mg/dl), and fasting glucose (ketogenic - 13.7 ± 8.4 mg/dl; low-GI nutrigenetic - 24.7 ± 7.4 mg/dl). The use of caffeine for enzyme assays: a critical appraisal. The answers were transformed into daily intake and compared with the recommendations of the World Health Organization (five or more servings per day). Intake of coffee was associated with an increased risk of nonfatal MI only among individuals with slow caffeine metabolism, suggesting that caffeine plays a role in this association. We evaluated potential gene × coffee interactions by determining the relation between coffee intake and the risk of MI for each genotype using conditional and unconditional logistic regression (with matching variables in the model) and by comparing –2 log (likelihood) ratios from a model with coffee and gene main effects only and from another that included their interaction term. The corresponding OR (95% CI) among those who were homozygous for the rapid *1A allele was 0.99 (0.66-1.48). The coronary events for subjects consuming little or no coffee (less than or equal to 1 cup per day) were compared with event rates for those consuming greater amounts of coffee. Coffee is a major source of caffeine, which is metabolized by the polymorphic cytochrome P450 1A2 (CYP1A2) enzyme. Articles published between 1966 and August 1991 examining a possible link between coffee and coronary heart disease were identified by a computer-aided literature search (Medline) and by standard bibliographic searches.

However, increased risk of myocardial infarction and hypertension has been suggested for individuals who carry a functional variant at cytochrome P450 1A2 (CYP1A2), which makes them less effective at metabolizing caffeine. The subjects self-selected whether to follow a standardized ketogenic diet (n = 53), or a personalised low-glycemic index (GI) nutrigenetic diet utilising information from 28 single nucleotide polymorphisms (n = 61). Participation for eligible cases and controls was 98% and 88%, respectively. Strong pharmacological synergism between CAF and HAL is demonstrated in myotubes prepared from adult HET and RYR1 channel recordings. Confounders included in the final models were smoking (never, past, 1-19 cigarettes/d, and ≥20 cigarettes/d); alcohol consumption (never, past, and tertiles of intake among current drinkers); history of diabetes (yes/no), history of hypertension (yes/no); quintiles of the continuous variables waist-hip ratio, physical activity, and income; and energy-adjusted intakes of sucrose, saturated fat, polyunsaturated fat, and trans fat. All data were analyzed using SAS version 8.2 (SAS Institute Inc, Cary, NC); P <.05 was considered statistically significant.

Kabagambe EK, Baylin A, Allan DA, Siles X, Spiegelman D, Campos H. Application of the method of triads to evaluate the performance of food frequency questionnaires and biomarkers as indicators of long-term dietary intake. Cornelis MC, El-Sohemy A, Kabagambe EK, Campos H. Coffee, CYP1A2 Genotype, and Risk of Myocardial Infarction. In comparison with non-dependent smoking, nicotine dependence was associated with current use of psychotropic medication, psychiatric morbidity, previous suicide attempt, and earlier AODS. Coffee contains other chemicals that may have adverse effects on the cardiovascular system.18 Distinguishing between the effects of caffeine and those of these other compounds has been difficult, given the strong collinearity between caffeine and coffee intake in many populations. Whether coffee consumption increases the risk of coronary heart disease has not yet been established. Results from a previous study indicated that a variant in the cytochrome P450 1A2 gene (CYP1A2) modifies the association between caffeinated coffee consumption and the risk of myocardial infection, ... One of the main variables included in our model was the rs762551 variant in the CYP1A2 gene. Cases (n = 2014) with a first acute nonfatal MI and population-based controls (n = 2014) living in Costa Rica between 1994 and 2004, matched for age, sex, and area of residence, were genotyped by restriction fragment-length polymorphism polymerase chain reaction. Design, Setting, and Participants Cases (n = 2014) with a first acute nonfatal MI and population-based controls (n = 2014) living in Costa Rica between 1994 and 2004, matched for age, sex, and area of residence, were genotyped by restriction fragment–length polymorphism polymerase chain reaction. Table 2 shows the risk of MI associated with coffee intake for all participants and by CYP1A2 genotype. Categorical and continuous nondietary and energy-adjusted dietary variables were assessed for potential confounding by measuring their effect on the model parameter estimates using the likelihood ratio test. In summary, consistent with most case-control studies, we found that increased coffee intake is associated with an increased risk of nonfatal MI. The odds ratios for 4 to 6 and 6 cups or more per day compared with up to 1 cup per day were 1.01 (0.90, 1.12) and 1.09 (0.97, 1.22), respectively. Indeed, for carriers of the *1F allele, a similar pattern of risk associated with coffee was observed among smokers and nonsmokers (Table 3). To determine whether CYP1A2 genotype modifies the association between coffee consumption and risk of acute nonfatal MI. Myers MG, Basinski A. Objective To determine whether CYP1A2 genotype modifies the association between coffee consumption and risk of acute nonfatal MI. After 24 weeks, the keto group lost more weight: - 26.2 ± 3.1 kg vs - 23.5 ± 6.4 kg (p = 0.0061). Context: The association between coffee intake and risk of myocardial infarction (MI) remains controversial. A diet-controlled study indicates that metabolic flexibility is an important driver of inter-individual difference in the response to dietary change, and a high flexibility score is a likely health asset. A2 adenosine receptors, located in coronary endothelial and smooth muscle cells, are responsible for stimulation of this enzyme activity.

Main Outcome Measure Relative risk of nonfatal MI associated with coffee intake, calculated using unconditional logistic regression. The positive association with heavy coffee drinking was present among nonsmokers as well as smokers. There were no PVT differences between ADORA2A genotypes (P > 0.05). The effects of adenosine are mediated by two distinct receptors (i.e., A1 and A2 receptors). JAMA. Ryanodine receptor (RYR1) mutations confer stress-triggered malignant hyperthermia susceptibility (MHS). Synergism of these drugs can be attributed to their actions at ryanodine receptors. However, at 18-month follow up, the personalised nutrition group (lowGI/NG) lost significantly more weight and experienced significantly greater improvements in measures of cholesterol and blood glucose. It has previously been suggested that coffee may be associated with an increased risk of MI only among younger individuals.7,8 To investigate whether age modified the interaction between CYP1A2 and coffee on risk of MI, we assessed risk separately for participants above and below the median age (59 years). We determined the interaction between coffee consumption and the tribbles pseudokinase 1 (TRIB1) rs17321515 variant on coronary heart disease (CHD).

Coffee, CYP1A2 genotype, and risk of myocardial infarction. They also were questioned on their use of psychotropic medication and previous suicide attempt. SIGNIFICANCE STATEMENT: Dietary caffeine attaining a human relevant plasma dose synergizes adverse peripheral and central responses to anesthesia in malignant hyperthermia susceptible mice. Coffee is a major source of caffeine, which is metabolized by the polymorphic cytochrome P450 1A2 (CYP1A2) enzyme. Acquisition of data: Cornelis, El-Sohemy, Campos. Each cohort was categorized by reported daily coffee consumption. Among slow metabolizers, the risk of a non-fatal myocardial infarction was increased in a logistic regression model correcting for cardiovascular risk factors (OR of MI 1.64, 95%CI 1.14-2.34) for 4 cups or more of coffee per day compared to 1 cup per day. The risk of myocardial infarction increased with increasing number of cups per day among both drinkers of any type of coffee and drinkers of caffeine-containing coffee only: tests for trend, p = 0.002 and p = 0.0004, respectively. to download free article PDFs, As an indication of potential psychopathology, our aim was to compare, in a non-psychiatric sample, the variables associated to daily smoking with those associated to nicotine dependence. Ranheim T, Halvorsen B. JAMA. The efficacy of caffeine supplementation is affected by the dose, method and timing of ingestion, training status, and the performance measures examined (Burke 2008;McLellan et al. A study by Leenaars and Lester (1995) found that suicide prevention centers in the provinces of Canada in 1985 had a preventive, but nonsignificant, impact on the suicide rates of the provinces. The consumption of green tea, coffee, and a combination of the beverages was associated with reduced all-cause mortality. The absence of an association between coffee and risk of MI in some case-control studies may have been due to a lower frequency of *1F carriers in the populations that were examined. Logistic regression analyses showed that nicotine dependence was associated with antecedents of suicide attempt and primary or lower education as well as with high caffeine use and the regular use of illegal drugs; in contrast, daily smoking showed a significant association with high caffeine use, the regular use of illegal drugs and lack of physical exercise. This intake was positively associated with income and years of schooling. Besides caffeine, no other major compound found in filtered coffee is known to be detoxified by CYP1A2. Plasma caffeine metabolite ratio (17X/137X) in vivo associated with G-2964A and C734 polymorphisms of human CYP1A2. Recently, it has been demonstrated that coffee consumption increases the risk of myocardial infarction only among individuals with slow metabolizer genotype [13], whereas among those with the 1A/ 1A genotype coffee even decreases the risk. The correlation coefficient for caffeine intake between seven 24-hour recalls and the average of 2 FFQ interviews was 0.83, and the correlation coefficient between both FFQs was 0.77.29 These results indicate high validity and reliability for the usual intake of coffee. The framework aims to provide dietitians with the necessary tools to evaluate and make decisions on the potential for translation of this technology to clinical practice for disease prevention and management. We also compared dependent and non-dependent smokers on these variables and on the age of onset of daily smoking (AODS). All Rights Reserved. However, it is not easy to suggest a moderate amount for the entire population concerning individual characteristics. Heterozygous R163C-RYR1 MHS mice (HET) are used to investigate the influences of dietary CAF on both peripheral and central responses before and after induction of halothane anesthesia (HAL).

ABSTRACT BACKGROUND: Coffee is one of the most widely consumed stimulants worldwide and is generally considered to be safe or even beneficial for health. Coffee, CYP1A2 Genotype, and Risk of Myocardial Infarction, Journal of American Medical Association, 295(10):1135-41. Physical features of subjects including genetic variations and body mass index (BMI) make it difficult to determine moderate intake of coffee for individuals in terms of caffeine metabolism. Coffee consumption and human health—beneficial or detrimental?—mechanisms for effects of coffee consumption on different risk factors for cardiovascular disease and type 2 diabetes mellitus. Neither polymorphism modified the association between coffee consumption and risk of MI; however, a significant coffee x HTR2Ainteraction was … When participants were stratified by CYP1A2 genotype, the increased risk of MI associated with coffee intake was observed only among carriers of the slow *1F allele (P = .04 for gene × coffee interaction). Cholesterol-raising factor from boiled coffee does not pass a paper filter. In this case-control study, patients had had their first acute myocardial infarction (AMI). There was no evidence for an interaction between the CYP1A2 genotype or caffeine-GS and coffee intake with respect to risk of CVD (P ≥ 0.53).  et al. These results suggest that this polymorphism is a causal factor of decreased CYP1A2 Individuals who are homozygous for the CYP1A2*1A allele are "rapid" caffeine metabolizers, whereas carriers of the variant CYP1A2*1F are "slow" caffeine metabolizers. For those individuals who were carriers of the *1F allele, the ORs (95% CIs) of MI associated with consuming less than 1, 1, 2 to 3, or 4 or more cups of coffee per day were 1.00 (reference), 1.24 (0.71-2.18), 1.67 (1.08-2.60), and 2.33 (1.39-3.89), respectively. Nutritional genomics is a fast-growing area of precision medicine. Genetic variation, especially CYP1A2 allele, To estimate the socioeconomic and sociodemographic factors associated with the daily intake of five servings of fruit and vegetables by elderly individuals living in low income areas, identifying the main fruits and vegetables which compose the diet of this population. Furthermore, the association between coffee consumption and unhealthy lifestyle factors suggests that previous associations might have been due to residual confounding.19. Because P-450IA2 is a monooxygenase that may be confined to the liver, caffeine reveals directly the Ah-receptor-dependent enzyme induction only in the liver, but it may also be a signal of induction elsewhere. Epidemiologic studies examining the association between coffee consumption and risk of myocardial infarction(MI) have been inconclusive. Thus, administration of adenosine or potentiators of adenosine production in the ischemic myocardium may be beneficial for the attenuation of ischemic and reperfusion injuries, although further clinical investigations are necessary. However, ischemia/reperfusion-induced coronary hyperemia is believed to be mostly attributed to released adenosine, and it has been proven that adenosine attenuates the severity of ischemia due to its coronary vasodilatory action. Data on CHD were obtained from the National Health Insurance Research Database (NHIRD) while genotype data were collected from the Taiwan Biobank (TWB) Database. The association between coffee intake and risk of myocardial infarction (MI) remains controversial [1, 2]. All data were collected by trained fieldworkers during an interview using 2 questionnaires consisting of closed-ended questions regarding smoking, sociodemographic characteristics, socioeconomic status, physical activity, diet, and medical history including use of medication and personal history of diabetes and hypertension. This point mutation was detected by a polymerase chain reaction-restriction 0.23 for the wild and mutated types of allele, respectively. The most striking finding was that CYP2E1 (the ethanol-inducible form) had major influences upon caffeine metabolism: in particular, it catalysed the formation of theophylline and theobromine from caffeine. Our findings show that coffee consumption increases the risk of MI only among individuals with a slow metabolizer genotype. Genetic susceptibility to tardive dyskinesia in chronic schizophrenia subjects, I: association of CYP1A2 gene polymorphism. It remained quite uniform when caffeine concentrations were varied.

Patients hospitalized for depression before or after the median time, 15 years and 2 months, between the first hospitalization for depression and AMI, were at similar risk. Research design and methods Corresponding ORs (95% CIs) among carriers of the *1F allele were 1.54 (1.03-2.32) for men and 2.83 (1.15-6.99) for women. A food frequency questionnaire was used to assess the intake of caffeinated coffee. Multivariable-adjusted hazard ratios (95% CIs) for green tea were as follows: none 1.0 (referent); 0.85 (0.60–1.22) for ≤1 cup/day; 0.73 (0.51–1.03) for 2–3 cups/day; 0.60 (0.42–0.85) for ≥4 cups/day; and P for trend, 0.002. Marilyn C. Cornelis; Ahmed El-Sohemy; Edmond K. Kabagambe; et al. Trial registration: In the present study, the frequency of carriers of the *1F allele was 54%, but frequencies have been reported to vary by population.35-38 Because cases in the present study experienced nonfatal MI, we cannot exclude the possibility that the observed interaction may affect survival after an acute MI.
