Enhanced liver fibrosis score is stable after withdrawal in patients with heavy alcohol consumption: A pilot study.

Enhanced liver fibrosis (ELF) score is an accurate, noninvasive test for assessing the severity of liver fibrosis in chronic liver disease, including alcohol-related liver disease. However, whether the ELF score changes during alcohol withdrawal is unknown. This pilot study assessed changes in the ELF score during withdrawal in patients with a history of excessive alcohol intake. In this prospective study, ELF was performed on day 0 (D0, at the beginning of hospitalization), at day 7 (D7, on discharge from hospital), and at follow-up visits on days 30 (D30) and 90 (D90). Transient elastography (TE) was also assessed on days 4 (D4) and D30. The study included 35 patients (71% male) with a mean alcohol intake of 139 g/day. On D30 and D90, 8 and 13 patients had resumed alcohol consumption (mean intake of 90 and 80 g/day, respectively). In patients who remained abstinent, the mean ELF score was 8.93 on D0, 9.14 on D30 (p = 0.32), and 9.27 on D90 (p = 0.14). In patients who resumed alcohol, mean ELF score was 9.7 on D0, 10.05 on D30 (p = 0.09), and 9.71 on D90 (p = 0.12). ELF score was comparable over the first months after withdrawal, although there was a slight increase in the first week (mean ELF score increased from 9.24 on D0 to 9.74 on D7, p < 0.001). Mean TE value was 7.9 kPa on D4 and 8.1 kPa on D30 (p = 0.84) in patients who resumed alcohol consumption, and 8.3 and 7.5 kPa (p = 0.03) on D4 and D30, respectively, in abstinent patients. The ELF score is stable during the first months after withdrawal and thus appears to be a useful tool to assess liver fibrosis or cirrhosis in this setting. Nevertheless, because in the first week there is a transient increase in ELF score, caution in interpretation is warranted.

Alcohol-related liver disease and liver transplantation

Alcohol-related liver disease (ALD) has become the major cause of liver transplantation (LT) in Korea, and is currently the most common cause of LT in Europe and the United States. Although, ALD is one of the most common indications for LT, it is traditionally not considered as an option for patients with ALD due to organ shortages and concerns about relapse. To select patients with terminal liver disease due to ALD for transplants, most LT centers in the United States and European countries require a 6-month sober period before transplantation. However, Korea has a different social and cultural background than Western countries, and most organ transplants are made from living donors, who account for approximately twice as many procedures as deceased donors. Most LT centers in Korea do not require a specific period of sobriety before transplantation in patients with ALD. As per the literature, 8%–20% of patients resume alcohol consumption 1 year after LT, and this proportion increases to 30%–40% at 5 years post-LT, among which 10%–15% of patients resume heavy drinking. According to previous studies, the risk factors for alcohol relapse after LT are as follows: young age, poor familial and social support, family history of alcohol use disorder, previous history of alcohol-related treatment, shorter abstinence before LT, smoking, psychiatric disorders, irregular follow-up, and unemployment. Recognition of the risk factors, early detection of alcohol consumption after LT, and regular follow-up by a multidisciplinary team are important for improving the short- and long-term outcomes of LT patients with ALD.

Phosphatidylethanol Detects Moderate‐to‐Heavy Alcohol Use in Liver Transplant Recipients

Alcohol-dependent liver transplantation (LT) patients who resume alcohol consumption are at risk for a number of alcohol-related problems including liver injury and liver failure. Post-LT patients are strongly advised to remain abstinent. However, we do not know how well this population complies due to a lack of valid methods (self-report and/or biomarkers) to identify alcohol use. Studies suggest as many as 50% resume alcohol use within 5years. Phosphatidylethanol (PEth) is a new cell-membrane phospholipid biomarker to identify alcohol use in the past 28days. This prospective study followed 213 LT recipients at 2 U.S. liver transplant centers. Sample included 213 LT subjects; 70.9% (n=151/213) had a history of alcohol dependence prior to transplantation and 29.1% (n=62/213) served as non-alcohol-dependent controls. Subjects participated in face-to-face interviews to assess alcohol use using a 30-day calendar. The protocol called for collecting blood samples at baseline, 6-, and 12-month follow-up. Seventy percent (149/213) who reported no alcohol use had consistently negative PEth levels (<8ng/ml). A total of 26.4% (57/213), 44 alcohol-dependent patients and 13 controls, had a positive PEth test of >8ng/ml either at baseline and/or during the follow-up period. Alcohol-dependent subjects (23.8%; n = 36/151) and 16.1% (n=10/62) controls reported no alcohol use but had at least 1 positive PEth test. Of the 11.2% (24/213) post-LT subjects who reported recent alcohol use, over half (11/24) had a positive PEth. The 13 self-reported alcohol users with a negative PEth level reported insufficient drinking to trigger PEth formation. Adoption of PEth as part of routine posttransplant care of LT recipients will enable early identification of patients at risk of alcohol use and facilitate abstinence in patients with a history of alcohol dependence and alcohol-related liver damage.

Regional brain volume changes in alcohol-dependent individuals during early abstinence: associations with relapse following treatment

Cross-sectional structural magnetic resonance (MR) imaging studies of individuals with an alcohol use disorder (AUD) report that those who relapse after treatment, relative to individuals who maintain a period of extended abstinence, show greater morphological abnormalities in multiple brain regions near the inception of treatment, particularly in the frontal lobe. However, given the cross-sectional design of previous studies, it is unclear if the baseline morphological differences between future abstainers and relapsers were maintained over the course of early recovery. The primary goal of this study was to determine if frontal lobe tissue volume recovery during early abstinence is associated with long-term abstinence from alcohol. We compared frontal, parietal, temporal and occipital grey matter (GM) and white matter (WM) volumes, at 1 and 4 weeks of abstinence, among individuals who resumed alcohol consumption within 12 months of treatment (Relapsers) and those who showed sustained abstinence over 12 months following treatment (Abstainers). At 1 and 4 weeks of sobriety, both Abstainers and Relapsers demonstrated significantly smaller GM volumes than Controls in the majority of ROIs, but Relapsers exhibited significantly smaller bilateral frontal GM volumes than Abstainers. No significant group differences were observed for any WM region of interest. The persistent bilateral frontal GM volume deficits in Relapsers over 4 weeks from last alcohol use may represent an endophenotype that differentiates those who respond more favorably to the typical psychosocial and pharmacological interventions provided for AUD.

Negative outcomes after liver transplantation in patients with alcoholic liver disease beyond the fifth post-transplant year.

Although up to 50% of patients with alcoholic liver disease (ALD) resume alcohol consumption after liver transplantation (LT), numerous studies indicate that long-term results are not compromised. This study focused on evaluating the impact of ALD on outcomes up to and beyond the fifth year after LT. Among the 432 primary LT recipients included in this study, 97 underwent transplantation for ALD. Alcohol relapse rate at 10yr was 33.5%, with younger recipient age being the only independent predictor (p=0.019). Survival of patients with ALD (77.0%) was similar to those without (79.0%) up to the fifth post-transplant year (p=0.655) but worse during the five subsequent years among the five-yr survivors (70.6% vs. 92.9%; p=0.002). ALD was an independent risk factor for poorer survival beyond the fifth post-transplant year (p=0.049), but not earlier (p=0.717). Conversely, alcohol relapse increased the risk of death only during the first five post-transplant years (p=0.039). There were no significant differences regarding graft failure incidence between ALD and non-ALD recipients up to the fifth post-transplant year (7.3% vs. 11.6%; p=0.255) and beyond (12.9% vs. 5.0%; p=0.126). In conclusion, pre-transplant diagnosis of ALD yields negative effects on post-transplant outcomes beyond the fifth post-transplant year, not attributable to recidivism.

Impact of the 2011 Great East Japan Earthquake on the Resumption of Alcohol Consumption After Living-Donor Liver Transplantation for Alcoholic Cirrhosis: A Report of Two Cases

Alcoholic liver disease (ALD) is a leading indication for liver transplantation (LT) in Western countries. The rate of resumption of alcohol abuse is 7% to 95% after LT for ALD. A high prevalence of alcohol abuse has been observed in disaster-exposed populations; however, little is known about the association between resumption of alcohol abuse after LT and disasters. Between June 2007 and March 2011, 3 patients with alcoholic cirrhosis (2 men and 1 woman) underwent living-donor LT (LDLT) at Tohoku University Hospital, Sendai, Japan. The female patient died of graft failure 6 months after LDLT. The other patients (ages 55 and 56 years), who survived to discharge, resumed alcohol abuse after the 2011 Great East Japan Earthquake. Before transplantation, both patients had been abusing alcohol for >35 years, with a daily ethanol intake of 110 g and 140 g, respectively. The period of abstinence from alcohol consumption ranged from 4 to 6 months. After transplantation, patients showed good compliance with treatment and seemed at low risk of relapse until the earthquake. One patient was living in the nuclear evacuation zone at Fukushima, and resumed alcohol consumption after the evacuation. Another patient resumed alcohol consumption while temporarily living apart from his family during restoration work after the disaster. Extreme stress and changes in living arrangements after the Great East Japan Earthquake seemed to trigger the desire to drink. This is the first report on patients who underwent LT for ALD and who resumed alcohol consumption after a disaster.

Phonoaudiology guidance in the preoperative period in the head and neck tumors.

Summary Introduction: The habit of smoking and intake of alcoholic drinks can lead to the incidence of malignant tumors in several areas, including the head or neck. Phonoaudiology is an area of oncology that is always seeking to expand its applications in oncological head and neck cases, with intervention in pre- and post-operative periods and in different clinical fields. Aim: To evaluate and describe the impact of phonoaudiology preoperative guidance in patients, specifically smokers and alcohol drinkers, with head and neck cancer. Methods: Series Study. Interviews were conducted by telephone with 40 individuals diagnosed with malignant head and neck tumors. Questionnaires regarding the use of tobacco and alcohol were administered before and after the phonoaudiology preoperative guidance. Results: Among the 40 individuals who received phonoaudiology preoperative guidance, 26 were smokers before the orientation. Of these 26 individuals, 18 (69.24%) abandoned tobacco dependence, 4 (15.38%) did not quit smoking, and 4 (15.38%) quit smoking for a few months before resuming smoking after receiving phonoaudiology preoperative guidance. Regarding alcohol consumption, 31 individuals ingested alcohol before phonoaudiology preoperative guidance. Of these 31 individuals, 17 (54.84%) abandoned alcohol dependence, 8 (25.81%) did not abstain from alcohol consumption, and 6 (19.35%) resumed alcohol consumption after a period of abstinence after receiving phonoaudiology preoperative guidance. Conclusion: Phonoaudiology preoperative orientations are effective in the treatment of head and neck malignant tumors.

Chronic Ethanol Consumption Inhibits Postlactational Anabolic Bone Rebuilding in Female Rats

EtOH consumption significantly impaired anabolic rebuilding of bone after lactation. Lower BMD and BMC in EtOH-fed rats were associated with decreased bone formation in the proximal tibia, increased proportion of adipocytes, and increased expression of TNF-alpha. EtOH-induced skeletal deficits were prevented by treatment with either NAC or sTNFR1. These data suggest that postlactational anabolic rebuilding is influenced by EtOH consumption and may affect the long-term risk of osteopenia. Despite significant loss of bone during lactation, BMD is restored by a powerful anabolic rebuilding process after weaning. A significant number of women resume alcohol consumption after weaning their offspring from breast feeding. The objectives of this study were to examine the consequences of chronic ethanol (EtOH) consumption on the postlactational rebuilding process and to investigate the underlying mechanisms by which EtOH mediates its detrimental effects. Female Sprague-Dawley rats (n = 7-9 per group) were fed EtOH-containing diets (13 g/kg/d) for 1, 2, or 4 wk after weaning of their offspring. Skeletal parameters in the proximal tibia were examined using pQCT, microCT, and histomorphometric techniques, and interventional studies were performed on the mechanistic roles of EtOH-induced oxidative stress and TNF-alpha. EtOH consumption completely abolished the anabolic bone rebuilding that occurred after lactation. Decreased BMD and BMC were associated with decreased bone formation and not with increased osteoclast activity. Furthermore, EtOH-fed rats showed greater proportion of fat volume/bone volume and expression of adipocyte-specific genes. EtOH-induced skeletal effects were mitigated by the dietary antioxidant, N-acetyl cysteine or by blocking TNF-alpha signaling. These data suggest EtOH consumption in the period immediately postweaning may significantly impair the mother's skeletal health and lead to long-term osteopenia.

Alcohol recidivism impairs long-term patient survival after orthotopic liver transplantation for alcoholic liver disease

The aim of this study was to evaluate the rate of alcohol recidivism after orthotopic liver transplantation (OLT) for alcoholic liver disease (ALD) and its influence on the allograft and patient survival, as well as the development of comorbidities and de novo cancers. The study was performed on 54 subjects previously analyzed and transplanted in our center for ALD, whose follow-up was prolonged to a mean of 99.2 (SD 31.7) months (range, 14-155). Medical records were reviewed, and data on alcohol consumption, therapeutic compliance, graft evolution, rejection, infections, comorbidities, rates of de novo malignancies and other clinical events, and survival were collected. Comparisons between groups were performed by the Fisher's exact test, and survival was assessed by the Kaplan-Meier method. Survival curves were compared using the Mantel-Cox statistic. The risk of death resulting from alcohol recidivism was analyzed with a Cox proportional hazards model. Fourteen patients who underwent transplantation for ALD (25.9%) returned to alcohol use between 5.0 and 86.9 months after OLT (median, 47.5). There was no significant association between the presence or absence of alcohol recidivism and the occurrence of graft rejection, infections, associated comorbidities after OLT, or compliance. The 5- and 10-year survival rates for patients with alcohol recidivism were 92.9% and 45.1%, respectively, compared with 92.4% and 85.5%, respectively, for patients without alcohol recidivism. These figures show significantly lower survival rates in recidivistic patients after 10 years (P < 0.01, Mantel-Cox). The fact that patients who resumed alcohol consumption have a worse 10-year survival rate might be attributed to a higher frequency of deaths, primarily from cancer and cardiovascular events.

Risk factors for continued cigarette use after subarachnoid hemorrhage.

Cigarette smoking is a risk factor for the formation and rupture of intracranial aneurysms. Few studies have examined predictors of resumption of cigarette smoking after a first episode of subarachnoid hemorrhage (SAH). Of 620 SAH patients treated between July 1996 and November 2002, we prospectively evaluated continued cigarette use in 152 smokers alive at 3 months. Univariate and multivariate logistic regression analyses were used to identify potential demographic, social, and clinical predictors of continued cigarette use, defined as smoking > or =1 cigarette per week in the month before follow-up. Thirty-seven percent (56 of 152) resumed smoking after their SAH. Patients who continued smoking were younger, were more often black, had begun smoking at an earlier age, and had a higher frequency of prior alcohol or cocaine use and self-reported depression or anxiety than those who quit (all P<0.05). Smoking at < or =16 years of age (odds ratio [OR], 5.88; 95% confidence interval [CI], 2.33 to 14.29), self-reported depression (OR, 5.29; 95% CI, 2.10 to 13.35), and prior alcohol use (OR, 4.51; 95% CI, 1.45 to 14.05) independently predicted continued cigarette use. Smokers had a functional outcome similar to that of nonsmokers at 3 months but were more likely to resume alcohol consumption (OR, 3.88; 95% CI, 1.91 to 7.88). More than one third of prior smokers continue to use nicotine after SAH. Young age at smoking onset and a history of depression or alcohol use are risk factors for continued cigarette use. Targeted smoking cessation programs are needed to reduce the high rate of smoking resumption after SAH.

Outcome of liver transplantation in critically ill patients with alcoholic cirrhosis: survival according to medical variables and sobriety.

At our center from August 1989 to December 1992, 834 adults underwent orthotopic liver transplantation (OLT) using tacrolimus as the primary immunosuppressive agent. A total of 183 adults (22%) had alcohol-related liver disease. Patients with alcoholic cirrhosis had a better though not statistically significant 5-year survival rate compared with all other patients. We were interested in specific predictors of survival, particularly for alcoholic cirrhotics who were gravely ill at the point of transplantation. For the 78 patients with alcohol-related liver disease who were United Network for Organ Sharing status IIA (critically ill) at the point of transplantation, variables of length of sobriety, alcohol rehabilitation, and medical variables (ventilator support, dialysis, vasopressor support, degree of encephalopathy, and infection) were assessed for contribution to survival. Although there was a trend toward poorer survival in patients with the shortest length of sobriety (< or =1 month), pre-OLT length of sobriety or alcohol rehabilitation did not predict survival. However, these patients tended to be in multiorgan failure and encephalopathic. Nevertheless, pre-OLT dialysis requirement was the only variable that predicted poorer survival (P < 0.002). This study was not designed to evaluate recidivism. However, we know that 24% of these patients have used alcohol at some point after OLT. Short pre-OLT length of sobriety may not predict which patients are likely to resume alcohol consumption after OLT, but it may identify patients in whom there will exist a variety of poor outcome variables. In our study, in these patients, post-OLT survival was associated with medical rather than alcohol history variables.

PRESSOR EFFECT OF ALCOHOL IN HYPERTENSION

The effect of alcohol on blood-pressure was studied in 16 men with hypertension who regularly drank up to 80 g of alcohol daily. Antihypertensive treatment was stopped 2 weeks before the men were admitted to hospital for a 7-day study. Blood pressure remained high in 8 patients who continued their regular alcohol consumption up to the fourth day after admission. In the next 4 days no alcohol was taken and diastolic and systolic blood pressures fell significantly. 8 other patients had no alcohol for the first 3 days after admission, but they resumed alcohol consumption from day 4 to 7. In these patients, blood pressure fell slightly after admission. Reintroduction of alcohol produced statistically significant increases in both systolic and diastolic pressures. This study demonstrated a pressor effect of alcohol in patients with hypertension and confirms the link between alcohol and blood-pressure reported in population studies. The mechanism of alcohol-induced hypertension is uncertain and is more likely to be due to an effect of alcohol rather than to the pressor response produced by alcohol withdrawal.

Neuropsychological consequences of posttreatment drinking behavior in male alcoholics

A prospective study was designed to determine the neuropsychological consequences of continued alcohol consumption after treatment for alcoholism. Performance on 24 commonly used clinical neuropsychological tests was examined in 56 male alcoholics approximately 7 months after completion of an inpatient alcoholism treatment program. Abstainers ( n=17) performed better than those who resumed alcohol consumption. Although there was a significant decrease in alcohol consumption, posttreatment drinking behavior still predicted cognitive performance, with increased frequency and quantity per occasion having more deleterious consequences even at consumption levels that are deemed by some to be socially acceptable. It is concluded that continued alcohol consumption by former alcoholics might serve to maintain cognitive performance at reduced levels, and that this possibility should be considered in determining appropriate treatment goals for alcoholic patients.
