    ABSTRACT: Alcohol is a risk factor for hypertension. Facial flushing after drinking is a typical symptom of high alcohol sensitivity. This study assessed the role of the facial flushing response in the relationship between alcohol consumption and hypertension. The subjects were 1,763 men (288 nondrinkers, 527 flushing drinkers, 948 nonflushing drinkers) who had received a health checkup. Data were collected from the subjects' medical records. The risk of hypertension related to weekly drinking amount in nonflushers and flushers was analyzed and compared with that in nondrinkers. After adjusting for age, body mass index, exercise status, and smoking status, the risk of hypertension was significantly increased when flushers consumed more than 4 drinks per week (more than 4 and up to 8 drinks: odds ratio [OR] = 2.23; above 8 drinks: OR = 2.35). In contrast, in nonflushers, the risk was increased with alcohol consumption of more than 8 drinks (OR = 1.61) per week. The OR (flushers/nonflushers) for hypertension was also increased: more than 4 and up to 8 drinks, 2.27 and above 8 drinks, 1.52. These findings suggest that hypertension associated with alcohol consumption has a lower threshold value and higher risk in flushers than in nonflushers. Clinicians should consider evaluating patients' flushing response as well as drinking amount in a daily practice for health promotion.

    ABSTRACT: It is believed that alcohol has an intimate connection with metabolic syndrome (MS). However, the role of facial flushing after alcohol consumption in this relationship has not yet been well known. We explored the relationship between weekly alcohol consumption, risk of MS, and the flushing response. The subjects were 1823 Korean adult males (305 nondrinkers, 540 flushers, 978 nonflushers) who had undergone a comprehensive medical check-up at Chungnam National University Hospital. We excluded the cases with the history of hypertension, diabetes, dyslipidemia, or who had taken medication in the previous month. After controlling for age, body mass index, exercise status, and smoking history, we used a logistic regression analysis to calculate the risk of MS with drinks per week in flushers and nonflushers as compared with nondrinkers. The risk of MS in flushers was significantly increased with alcohol consumption >4 drinks (4-16 drinks: odds ratio [OR] 1.93; >16 drinks: OR 2.20). However, in nonflushers, the risk of MS was increased in those consuming >16 drinks (OR 2.02). Our results suggest that the threshold for MS from alcohol consumption is lower in flushers than in nonflushers.

    ABSTRACT: Patients' insight has a critical role in the recovery from problematic behavior. The aim of this study was to evaluate the effects of a brief intervention to promote insight among alcohol-dependent patients. A total of 41 alcohol-dependent patients (30 males, 11 females) in an insight-deficient state who had been admitted to a community-based alcohol treatment center, were randomized into two groups based on their admission order: an intervention group (IG) (n = 20) and a control group (CG) (n = 21). Patients in both the IG and CG participated in an identical treatment program with one exception: patients in the IG were required to undergo five sessions of brief individual intervention focusing on insight enhancement. Changes in insight state were assessed after the intervention. The IG exhibited significant (P < 0.05) changes in the distribution of insight level, while the CG did not exhibit any significant changes in the distribution of insight level. The insight score after intervention was significantly (P < 0.05) greater for the IG than the CG with adjustment for the baseline characteristics. The results suggest that a brief individual intervention focused on insight enhancement may be an effective tool to improve insight among alcohol-dependent patients.

    ABSTRACT: Facial flushing responses to drinking, because of intolerance to alcohol, are observed in some people, especially Asians. This study examined the role of flushing responses in the relationship between alcohol consumption and insulin resistance (IR). Participants in this cross-sectional analysis included 624 Korean men (80 nondrinkers, 306 nonflushing drinkers, and 238 flushing drinkers) who were free of cardiovascular disease and diabetes. Data on the flushing response to drinking and alcohol consumption were collected from medical records. IR was estimated using the Homeostasis Model Assessment (HOMA(IR) ). On the basis of comparisons with nondrinkers, the risk of IR according to the quantity of alcohol consumed per week was analyzed among nonflushers and flushers. After adjusting for age, exercise status, smoking status, BMI, waist circumference, blood pressure, high-density lipoprotein cholesterol, and triglycerides using a logistic regression model, we found a low risk of IR among nonflushers who consumed ≤4 drinks (1 drink = 14 g of alcohol) per week (OR = 0.3). In contrast, a higher risk of IR was associated with nonflushers who consumed >20 drinks per week (OR = 3.5). On the other hand, only a higher risk of IR was associated with flushers who consumed >12 drinks per week (>12 to 20 drinks: OR = 4.7; >20 drinks: OR = 3.5). The amount of drinking associated with the development of IR in flushers was lower than in nonflushers. Additionally, no positive effect of moderate drinking on IR was observed in flushers. The findings support acetaldehyde-derived mechanisms in the development of alcohol-related IR.

    ABSTRACT: Hypertension is a major risk factor for the development of cardiovascular disease. The prevalence of secondary hypertension, 10% is known as a common cause of resistant hypertension. Development of diagnostic technology and the aging is likely to be increased of the prevalence. Secondary hypertension, if it is not appropriate etiologic treatment may sometimes be fatal, as well as to the proper treatment be treatable or curable hypertension. Secondary causes of hypertension include a greater prevalence of obstructive sleep apnea, renal parenchymal disease, renovascular disease and primary aldosteronism. Uncommon secondary causes include pheochromocytoma, Cushing's syndrome, hyperparathyroidism and thyroid disease. Clinical clues for secondary hypertension is onset of hypertension in persons younger than age 20 or older than age 50 without family history of hypertension, poor response to therapy, worsening of control in previously stable hypertensive patient, markedly elevated blood pressure or hypertension with severe end-organ damage, presence of abdominal bruit (renal artery stenosis), moon face and abdominal striae (Cushing's syndrome), paroxysmal headaches and palpitations (pheochromocytoma), pronounced hypokalemia due to low dose diuretic therapy (primary aldosteronism), acute renal failure or hypokalemia after initiation of angiotensin converting enzyme inhibitors or angiotensin II receptor blocker (renal artery stenosis), hypercalcemia (hyperparathyroidism), snoring and daytime somnolence (obstructive sleep apnea). A combination of a good history and physical examination, astute observation, and accurate interpretation of available data usually are helpful in the diagnosis of a specific causation. This article provides an overview of the range of secondary hypertension, including key clinical features, appropriate diagnostic approach and treatment for primary physician.
