Effectiveness of a Web-Based Individual Coping and Alcohol Intervention Program for Children of Parents With Alcohol Use Problems: Randomized Controlled Trial

BACKGROUND

Children whose parents have alcohol use problems are at an increased risk of several negative consequences, such as poor school performance, an earlier onset of substance use, and poor mental health. Many would benefit from support programs, but the figures reveal that only a small proportion is reached by existing support. Digital interventions can provide readily accessible support and potentially reach a large number of children. Research on digital interventions aimed at this target group is scarce. We have developed a novel digital therapist-assisted self-management intervention targeting adolescents whose parents had alcohol use problems. This program aims to strengthen coping behaviors, improve mental health, and decrease alcohol consumption in adolescents.

OBJECTIVE

This study aims to examine the effectiveness of a novel web-based therapist-assisted self-management intervention for adolescents whose parents have alcohol use problems.

METHODS

Participants were recruited on the internet from social media and websites containing health-related information about adolescents. Possible participants were screened using the short version of the Children of Alcoholics Screening Test-6. Eligible participants were randomly allocated to either the intervention group (n=101) or the waitlist control group (n=103), and they were unblinded to the condition. The assessments, all self-assessed, consisted of a baseline and 2 follow-ups after 2 and 6 months. The primary outcome was the Coping With Parents Abuse Questionnaire (CPAQ), and secondary outcomes were the Center for Epidemiological Studies Depression Scale, Alcohol Use Disorders Identification Test (AUDIT-C), and Ladder of Life (LoL).

RESULTS

For the primary outcome, CPAQ, a small but inconclusive treatment effect was observed (Cohen d=-0.05 at both follow-up time points). The intervention group scored 38% and 46% lower than the control group on the continuous part of the AUDIT-C at the 2- and 6-month follow-up, respectively. All other between-group comparisons were inconclusive at either follow-up time point. Adherence was low, as only 24% (24/101) of the participants in the intervention group completed the intervention.

CONCLUSIONS

The findings were inconclusive for the primary outcome but demonstrate that a digital therapist-assisted self-management intervention may contribute to a reduction in alcohol consumption. These results highlight the potential for digital interventions to reach a vulnerable, hard-to-reach group of adolescents but underscore the need to develop more engaging support interventions to increase adherence.

Opioid analgesia and severity of acute pancreatitis: An international multicentre cohort study on pain management in acute pancreatitis

BACKGROUND

The effect of analgesic modalities on short-term outcomes in acute pancreatitis remains unknown. However, preclinical models have raised safety concerns regarding opioid use in patients with acute pancreatitis.

OBJECTIVE

This study aimed to assess the association between analgesics, particularly opioids, and severity and mortality in hospitalised patients with acute pancreatitis.

METHODS

This prospective multicentre cohort study recruited consecutive patients admitted with a first episode of acute pancreatitis between April 1 and 30 June 2022, with a 1-month follow-up. Data on aetiology, clinical course, and analgesic treatment were collected. The primary outcome was the association between opioid analgesia and acute pancreatitis severity, which was analysed using univariate and multivariate analyses.

RESULTS

Among a total of 1768 patients, included from 118 centres across 27 countries, 1036 (59%) had opioids administered on admission day, and 167 (9%) received opioids after admission day. On univariate analysis, moderately severe or severe acute pancreatitis was associated with male sex, Asian ethnicity, alcohol aetiology, comorbidity, predicted severe acute pancreatitis, higher pain scores, longer pain duration and opioid treatment (all p < 0.001). On multivariate analysis, comorbidity, alcohol aetiology, longer pain duration and higher pain scores increased the risk of moderately severe or severe acute pancreatitis (all p < 0.001). Furthermore, opioids administered after admission day (but not on admission day) doubled the risk of moderately severe or severe disease (OR 2.07 (95% CI, 1.29-3.33); p = 0.003). Opioid treatment for 6 days or more was an independent risk factor for moderately severe or severe acute pancreatitis (OR 3.21 (95% CI, 2.16-4.79; p < 0.001). On univariate analysis, longer opioid duration was associated with mortality.

CONCLUSION

Opioid treatment increased the risk of more severe acute pancreatitis only when administered after admission day or for 6 days or more. Future randomised studies should re-evaluate whether opioids might be safe in acute pancreatitis.

Ulysses S. Grant: Chronic Malaria and the myth of his alcoholism

Ulysses S. Grant, Civil War general and twice-elected President of the United States, was highly respected in late-19th century America. Gradually however, it became the conventional wisdom that he was an alcoholic who had only succeeded as a general by using overwhelming force. This change began with his political enemies and those who resented his suppression of the Ku Klux Klan, his regard for the welfare of Native Americans and his support of Reconstruction. Jealous subordinates and those with an axe to grind added their voices to this and then the views of certain influential academic historians and romantic adherents of 'The Lost Cause' were unchallenged until the mid-1950s. Grant was undoubtedly an occasional binge drinker but this is not the same as being an alcoholic. Charles A. Dana is the most authoritative source for the claim that Grant was a frank alcoholic. In 1887 he wrote that Grant was drunk on a trip to Satartia, Mississippi in 1863 during the siege of Vicksburg. In this paper, the author shows that Grant was actually ill on that trip from the disease of malaria, alcohol was not involved at all, and that Grant suffered episodically from this disease both before and during the Civil War.

Analysis of 21 Patients With Alcoholic Marchiafava-Bignami Disease in Chongqing, China

OBJECTIVE

This study aimed to investigate the characteristics and prognosis of patients with alcoholic Marchiafava-Bignami disease (MBD), a rare neurological disorder commonly associated with chronic alcoholism, in Chongqing, China.

METHODS

We conducted a retrospective analysis of clinical data from 21 alcoholic MBD patients treated at the First Affiliated Hospital of Chongqing University between 2012 and 2022.

RESULTS

The study included 21 patients with alcoholic MBD who had a mean age of 59 ± 9.86 years and an average drinking history of 35.48 ± 8.65 years. Acute onset was observed in 14 (66.7%) patients. The primary clinical signs observed were psychiatric disorders (66.7%), altered consciousness (61.9%), cognitive disorders (61.9%), and seizures (42.9%). Magnetic resonance imaging revealed long T1 and long T2 signal changes in the corpus callosum, with lesions predominantly found in the genu (76.2%) and splenium (71.4%) of the corpus callosum. The poor prognosis group demonstrated an increased incidence of altered consciousness (100% vs 50%, P = 0.044), pyramidal signs (80% vs 18.8%, P = 0.011), and pneumonia (100% vs 31.3%, P = 0.007). Patients with a longer drinking history (45.0 ± 10.0 years vs 32.69 ± 5.99 years, p = 0.008) and a lower thiamine dose (p = 0.035) had a poorer prognosis at 1 year.

CONCLUSIONS

This study identified altered consciousness, pyramidal signs, and pneumonia as predictors of a poor prognosis in patients with alcoholic MBD. A longer duration of alcohol consumption and inadequate thiamine supplementation were associated with a poorer prognosis.

Effects of Curative-Intent Treatments on Hepatocellular Carcinoma Survival in Alcohol-Related Cirrhosis: A Nationwide Study

Purpose

The aim of curative-intent treatment for hepatocellular carcinoma (HCC) is to restore the patients' survival to what it would have been, had they not developed HCC. We examined the chances of such 'statistical cure' from HCC in patients with cirrhosis due to alcohol-related liver disease (ALD cirrhosis).

Patients and Methods

Using nationwide Danish healthcare registries, all patients with ALD cirrhosis who were treated for HCC in 2004-2018 were identified and included in cohorts based on initial HCC treatment. We used cure fraction analyses to estimate the chance of being statistically cured by each HCC treatment.

Results

We included 1087 patients with HCC due to ALD cirrhosis, of whom 51 (4.7%) were treated with resection and 215 (19.8%) were treated with ablation. The cure fraction, ie the fraction of patients who experienced no excess mortality from HCC, was 31.8% (95% CI: 0.0-67.5) following resection and 22.9% (95% CI: 2.6-43.2) following ablation. In patients who were still alive five years after the initial HCC treatment, the likelihood of having been statistically cured at that time was 69.0% after resection and 60.2% after ablation. For both treatments, a 90% chance of having been statistically cured was reached after seven years.

Conclusion

Based on cure fraction analyses, resection for HCC statistically cures 31.8% of patients with HCC and underlying ALD cirrhosis, while ablation statistically cures 22.9% of patients. Seven years after curative-intent treatments for HCC, surviving patients are 90% likely to be statistically cured of HCC. This information is valuable to patients and the clinicians caring for them.

Effect of alcohol consumption on relapse outcomes among tuberculosis patients: A systematic review and meta-analysis

Introduction

Tuberculosis (TB) is one of the major public health issues in every country. Alcohol consumption is one of the reasons associated with the severity of symptoms and death among TB patients. The impact of alcohol use on TB relapse outcomes is still debatable. This study aimed to conduct a systematic review and meta-analysis (SR/MA) to find the link between alcohol use and TB relapse outcomes.

Methods

Data collection was performed from December 2021 to March 2022; and was obtained from electronic databases including CINAHL, PubMed, and Scopus. The researcher carefully searched and reviewed all the relevant research concerning drinking alcohol and relapse outcomes among TB patients. A set of inclusion and exclusion criteria was used to assess research publications. The methodological quality of eligible publications was assessed using the Newcastle-Ottawa Scale. Random meta-analysis was used to determine odds ratios (ORs) with a 95% confidence interval (CIs). The funnel plot, Begg's test, and Egger's test were employed to investigate publication bias.

Results

There were a total of 2,113 studies found and reviewed, and eight publications were chosen for the analysis. It was found that among TB patients with a moderate appearance of heterogeneity, drinking alcohol increases the probability of relapse (OR = 3.64; 95% CI: 2.26-5.88, p < 0.001) and mortality (OR = 1.72; 95% CI: 1.40-2.12, p < 0.001). The funnel plot, Begg's test, and Egger's test all revealed that there was no indication of publication bias.

Conclusions

Relapses and mortality among tuberculosis patients are considerably increased by alcohol drinking. More research into the causality of this link between the degree of alcohol use and the underlying processes is required.

Removal of copper ions from alembic cachaça using agro-industrial residues as biosorbents

Cachaça is a typical Brazilian distilled beverage made from fermented sugarcane juice. The copper levels in alembic cachaça are of great concern among producers, and the removal of this contaminant is important for the quality of the product. The present study aimed to remove copper ions from alembic cachaça by adsorption. Sugarcane bagasse, okara, Moringa oleifera Lam., three different types of zeolites, and two types of commercial charcoal were tested as biosorbents. The heat-treated sugarcane bagasse removed 100% of the copper present in a cachaça sample, while other low-cost natural adsorbents had close to 50% removal as was observed for M. oleifera seeds and okara. All adsorbents had porous and fibrous structures, favorable to adsorption. A kinetic study showed that a pseudo-second-order model was appropriate, with equilibrium times of 15 h for heat-treated sugarcane bagasse, okara, and M. oleifera seeds used as adsorbents. The Langmuir model better fitted the experimental data, indicating monolayer adsorption. The maximum adsorption capacity was 17.00, 0.77, and 5.33 mg of Cu g^-1 for the heat-treated sugarcane bagasse, M. oleifera seeds, and okara, respectively. The results presented here are promising indicating three agro-industrial residues were favorable to the adsorption of copper ions from alembic cachaça.

COVID-19 patients with documented alcohol use disorder or alcohol-related complications are more likely to be hospitalized and have higher all-cause mortality

BACKGROUND

Coronavirus Disease 2019 (COVID-19) has affected every country globally, with hundreds of millions of people infected with the SARS-CoV-2 virus and over 6 million deaths to date. It is unknown how alcohol use disorder (AUD) affects the severity and mortality of COVID-19. AUD is known to increase the severity and mortality of bacterial pneumonia and the risk of developing acute respiratory distress syndrome. Our objective is to determine whether individuals with AUD have increased severity and mortality from COVID-19.

METHODS

We utilized a retrospective cohort study of inpatients and outpatients from 44 centers participating in the National COVID Cohort Collaborative. All were adult COVID-19 patients with and without documented AUDs.

RESULTS

We identified 25,583 COVID-19 patients with an AUD and 1,309,445 without. In unadjusted comparisons, those with AUD had higher odds of hospitalization (odds ratio [OR] 2.00, 95% confidence interval [CI] 1.94 to 2.06, p < 0.001). After adjustment for age, sex, race/ethnicity, smoking, body mass index, and comorbidities, individuals with an AUD still had higher odds of requiring hospitalization (adjusted OR [aOR] 1.51, CI 1.46 to 1.56, p < 0.001). In unadjusted comparisons, individuals with AUD had higher odds of all-cause mortality (OR 2.18, CI 2.05 to 2.31, p < 0.001). After adjustment as above, individuals with an AUD still had higher odds of all-cause mortality (aOR 1.55, CI 1.46 to 1.65, p < 0.001).

CONCLUSION

This work suggests that AUD can increase the severity and mortality of COVID-19 infection. This reinforces the need for clinicians to obtain an accurate alcohol history from patients hospitalized with COVID-19. For this study, our results are limited by an inability to quantify the daily drinking habits of the participants. Studies are needed to determine the mechanisms by which AUD increases the severity and mortality of COVID-19.

Clinical analysis of alcoholic pellagra: A single-center retrospective study

BACKGROUND

Pellagra caused by niacin deficiency in alcoholics can be easily misdiagnosed because of similar symptoms to other alcohol-related diseases and the lack of the classical triad of signs.

AIM

This study aimed to define the clinical presentation of alcoholic pellagra for early diagnosis and timely treatment.

METHODS

The clinical data of 16 alcohol-dependent patients who had pellagra and treated in our hospital from January 2002 to December 2019 were retrospectively analyzed. The local medical ethics committee approval (Medical Ethics Committee of Affiliated Hospital of XuZhou Medical University, XYFY2020-KL247-02) for this study have been obtained.

RESULTS

The main complaints of the 16 patients were skin lesions (six cases), diarrhea (six cases), and mental disorders (four cases). Then, 13 cases had typical skin lesions, and 3 patients had a full spectrum of diarrhea, dementia, and dermatitis (3D). In terms of the main diagnosis, 2 patients had pellagra and Wernicke's encephalopathy, 3 patients had pellagra and alcohol-withdrawal syndrome, and the other patients had pellagra. After sufficient amounts of niacin and multivitamin B were given, clinical symptoms improved rapidly, and no sequelae were observed during follow-up.

CONCLUSIONS

Pellagra is rarely manifested as a full 3D spectrum, with only one or two characteristics, which lack diagnostic specificity, especially in individuals with alcoholism. Physicians should maintain a high degree of suspicion of niacin deficiency in alcoholics. Alcohol-dependent patients with pellagra may be accompanied by complications of Wernicke's encephalopathy and alcohol-withdrawal syndrome. Prompt identification and timely treatment with a sufficient amount of niacin in combination with other vitamins and a certain amount of Zn can achieve a good prognosis of pellagra.

FACTORS CONTRIBUTING TO THE ESCALATION OF ALCOHOL CONSUMPTION

Understanding factors that contribute to the escalation of alcohol consumption is key to understanding how an individual transitions from non/social drinking to AUD and to providing better treatment. In this review, we discuss how the way ethanol is consumed as well as individual and environmental factors contribute to the escalation of ethanol consumption from intermittent low levels to consistently high levels. Moreover, we discuss how these factors are modelled in animals. It is clear a vast array of complex, interacting factors influence changes in alcohol consumption. Some of these factors act early in the acquisition of ethanol consumption and initial escalation, while others contribute to escalation of ethanol consumption at a later stage and are involved in the development of alcohol dependence. There is considerable need for more studies examining escalation associated with the formation of dependence and other hallmark features of AUD, especially studies examining mechanisms, as it is of considerable relevance to understanding and treating AUD.

[Diagnosis and Severity Assessment of Alcohol-Related Liver Disease]

A diagnosis of alcohol-related liver disease (ALD) requires information on the history of excessive alcohol consumption (average intake of 40 g or more in men and 20 g or more in women a day). Furthermore, blood tests, such as GGT, AST, ALT, and mean corpuscular volume, and imaging studies, including abdominal ultrasound or transient elastography, are also useful. A liver biopsy can be useful for confirming the diagnosis and has prognostic value. ALD includes alcoholic fatty liver, alcoholic hepatitis, and alcoholic cirrhosis, and in most cases, clinical manifestations can overlap. The prognostic scoring systems of ALD are limited mainly to alcoholic hepatitis, and the early mortality and treatment response can be predicted using various scoring systems. This review summarizes how to diagnose and evaluate the severity of ALD in clinical practice.

Negative trends in outpatient care of addicted patients in Hungary

OBJECTIVES

This article investigates how the numbers of registered addict patients have changed in the last three decades in Hungary and whether the predicted HIV epidemic among intravenous drug users has occurred.

METHODS

Data were collected from the Annual Reports of the National Bureau of Statistics and National Epidemiological Centre as well as from the medical records of the author.

RESULTS

The total number of registered alcoholics decreased by about 75% during the investigated period. This decrease was more pronounced among males than females. After initial increase, the number of registered drug addicts showed stagnation with an about 50% drop-out rate. Fortunately, the anticipated HIV epidemic did not manifest. The negative effect of a poor political action upon the number of client visits could, however, be documented.

CONCLUSION

In conclusion, negative trends are seen in the Hungarian addiction care. Numerous variables may be taken into consideration as affecting factors, but it is not yet clear to what extent these negative factors are responsible for trends. These data, however, warrant further investigations.

Compensated Cirrhosis Is Associated With Increased Risk of Complications Following Total Hip Arthroplasty in a Large Medicare Database

BACKGROUND

The aim of this study is to evaluate medical and surgical complications of liver cirrhosis patients following total hip arthroplasty (THA), with attention to different etiologies of cirrhosis and their financial burden following THA.

METHODS

In total, 18,321 cirrhotics and 722,757 non-cirrhotics who underwent primary elective THA between 2006 and 2013 were identified from a retrospective database review. This cohort was further subdivided into 2 major etiologies of cirrhosis (viral and alcoholic cirrhosis) and other cirrhotic etiology. Cirrhotics were compared to non-cirrhotics for hospital length of stay, 90-day mean total charges and reimbursement, hospital readmission, and major medical and arthroplasty-specific complications.

RESULTS

Cirrhosis was associated with increased rates of major medical complications (4.3% vs 2.4%; odds ratio [OR] 1.20, P < .001), minor medical complications, transfusion (3.4% vs 2.1%; OR 1.16, P = .001), encephalopathy, disseminated intravascular coagulation, and readmission (13.5% vs 8.6%; OR 1.18, P < .001) within 90 days. Cirrhosis was associated with increased rates of revision, periprosthetic joint infection, hardware failure, and dislocation within 1 year postoperatively (3.1% vs 1.6%; OR 1.37, P < .001). Cirrhosis independently increased hospital length of stay by 0.14 days (P < .001), and it independently increased 90-day charges and reimbursements by $13,791 (P < .001) and $1707 (P < .001), respectively. Viral and alcoholic cirrhotics had higher rates of 90-day and 1-year complications compared to controls-other causes only had higher rates of 90-day medical complications, encephalopathy, readmission, and 1-year revision, hardware failure, and dislocation compared to controls.

CONCLUSION

Cirrhosis, especially viral and alcoholic etiologies, is associated with higher risk of early postoperative complications and healthcare utilization following elective THA.

[Current Status of Deceased Donor Liver Transplantation for Alcoholic Liver Disease in Korea in MELD Era]

The organ allocation system should be fair and efficient to predict the prognosis of patients with end-stage organ failure. The liver allocation system in Korea was changed to the model for end-stage liver disease (MELD) score system from Child-Turcotte-Pugh score-based status system in 2016. Since then, there have been some changes in matching liver graft to recipients in deceased liver transplantation. The severity of sickness of the end-stage liver failure patients has been increased in the MELD era than before. Since 2013, liver transplantation for alcoholic liver disease has been gradually increasing in Korea. We should take proper evaluation into consideration when we decide early liver transplantation particularly for patients with severe alcoholic hepatitis, who have a high MELD score. Above all, overcoming organ shortage, it is necessary for us to try to increase the number of deceased donors to meet the need for liver transplantation for end-stage liver disease patients.

Prognostic value of the controlling nutritional status (CONUT) score in intrahepatic cholangiocarcinoma patients especially who had long-time alcohol consumption

Our study is to investigate the preoperative prognostic value of the Controlling Nutritional Status score in intrahepatic cholangiocarcinoma patients after curative resection. One hundred and sixty-seven patients admitted to our hospital between January 2012 and December 2018 were included retrospectively. Time-dependent receiver operating characteristic (ROC) curve analysis was conducted to evaluate the ability of the Controlling Nutritional Status score to predict recurrence and survival. Patients with high Controlling Nutritional Status score (≥3) had significantly poorer RFS compared to those with low Controlling Nutritional Status score (low: <3) (p = 0.000) in Kaplan-Meier survival curve. Multivariate analyses identified Controlling Nutritional Status score, lymph node metastasis, tumor numbers and preoperative CEA as independent prognostic factors for RFS. Lymph node metastasis was the independent risk factor of OS. The Cox regression model with Controlling Nutritional Status score had better prognostic value for recurrence than the Cox regression model without Controlling Nutritional Status score in long-time alcohol consumption intrahepatic cholangiocarcinoma patients (AUC: 0.760 vs 0.706, p = 0.036). CONUT score may be a more powerful prognostic biomarker, which is tightly associated with other tumor characteristics, to predict recurrence but not survival, especially in long-time alcohol consumption intrahepatic cholangiocarcinoma patients after curative-intent surgery.

Addition of trans fat and alcohol has divergent effects on atherogenic diet-induced liver injury in rodent models of steatohepatitis

Nonalcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD) are common causes of chronic liver disease. The overlap between ALD and NAFLD suggests the existence of metabolic steatohepatitis. Development of in vivo models that reflect various aspects of human steatohepatitis is essential for drug discovery. We aimed to characterize several models of steatohepatitis (SH) and to investigate whether the pathology could be modulated. Sprague-Dawley rats were fed a high-fat diet (HFD) for 9 wk, followed by either a high-fat, high-cholesterol and cholate diet (HFC) or a HFC diet containing 13% trans fat (HFC-TF). A subset received 15% ethanol-water twice a week for 12 wk. Serum triglycerides, cholesterol, LDL, HDL, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and rodent NH₂-terminal propeptide of type III collagen (rPRO-C3) were assessed. The liver was weighed and evaluated using modified Nonalcoholic Steatohepatitis Clinical Research Network histological score system criteria. All diets induced hepatomegaly, but only HFC-TF increased the size of visceral adipose tissue. Trans fat augmented HFC-induced dyslipidemia, and cholesterol was higher and HDL was lower in the HFC-TF groups. Alcohol lowered triglycerides in both dietary groups. HFC elevated ALT and AST, which were lowered by trans fat. All diets induced histological SH, addition of trans fat induced more steatosis but less inflammation. Inclusion of alcohol augmented the HFC-induced inflammation. All diets induced mild fibrosis. Inclusion of trans fat and alcohol significantly increased rPRO-C3. The addition of trans fat reduced the HFC-induced inflammation but augmented steatosis and dyslipidemia. Inclusion of alcohol induced a more inflammatory and fibrogenic phenotype.NEW & NOTEWORTHY Alcoholic liver disease and nonalcoholic liver disease share significant overlap, which suggests the existence of metabolic steatohepatitis. Trans fat has been implicated in steatohepatitis development. Here, we show that the addition of trans fat to an atherogenic diet results in a more steatotic but less inflammatory phenotype, whereas the addition of alcohol to an atherogenic diet augments the inflammatory and fibrogenic properties of the diet.

Hydrogen sulphide production by Saccharomyces cerevisiae UCD 522 in a synthetic grape juice medium deficient of thiamin (vitamin B1 ) and/or pyridoxine (vitamin B6 )

The impacts of thiamin and pyridoxine along with YAN on alcoholic fermentation and hydrogen sulphide production by Saccharomyces cerevisiae were studied. Using a synthetic grape juice medium, three fermentation trials were conducted; (i) 2 × 3 factorial design with thiamin (0, 0·2, or 0·5 mg l^-1 ) and YAN (60 or 250 mg l^-1 ) as variables, (ii) 2 × 3 factorial design with pyridoxine (0, 0·25, or 0·5 mg l^-1 ) and YAN (60 or 250 mg l^-1 ) as variables, and (iii) 3 × 3 factorial design with thiamin (0, 0·2 or 0·5 mg l^-1 ) and pyridoxine (0, 0·25 or 0·5 mg l^-1 ) as variables in media containing 60 mg l^-1 YAN. Although the progress of fermentations was affected by thiamin or pyridoxine, YAN had a larger impact than either vitamin. H₂ S production was significantly lower with increasing amounts of thiamin in those fermentations under low YAN (60 mg l^-1 ) while even lower amounts (<30 µg l^-1 ) were produced under high YAN (250 mg l^-1 ) with or without the vitamin. The highest amounts of H₂ S were synthesized in those fermentations without any pyridoxine (>110 µg l^-1 ), with the lowest production in media with pyridoxine and high YAN (<20 µg l^-1 ). SIGNIFICANCE AND IMPACT OF THE STUDY: Concentrations of thiamin, pyridoxine and yeast assimilable nitrogen (YAN) influenced the synthesis of hydrogen sulphide (H₂ S) by Saccharomyces cerevisiae in a synthetic grape juice medium. With a few exceptions, an increase in the concentration of either vitamin or YAN resulted in less H₂ S released. This is the first report to demonstrate that both thiamin and pyridoxine along with YAN affected H₂ S production, emphasizing the need to assess yeast nutrients to lower risks of off-odours during fermentation.

Brain-behavior relations and effects of aging and common comorbidities in alcohol use disorder: A review

OBJECTIVE

Alcohol use disorder (AUD) is a complex, dynamic condition that waxes and wanes with unhealthy drinking episodes and varies in drinking patterns and effects on brain structure and function with age. Its excessive use renders chronically heavy drinkers vulnerable to direct alcohol toxicity and a variety of comorbidities attributable to nonalcohol drug misuse, viral infections, and accelerated or premature aging. AUD affects widespread brain systems, commonly, frontolimbic, frontostriatal, and frontocerebellar networks.

METHOD AND RESULTS

Multimodal assessment using selective neuropsychological testing and whole-brain neuroimaging provides evidence for AUD-related specific brain structure-function relations established with double dissociations. Longitudinal study using noninvasive imaging provides evidence for brain structural and functional improvement with sustained sobriety and further decline with relapse. Functional imaging suggests the possibility that some alcoholics in recovery can compensate for impairment by invoking brain systems typically not used for a target task but that can enable normal-level performance.

CONCLUSIONS

Evidence for AUD-aging interactions, indicative of accelerated aging, together with increasing alcohol consumption in middle-age and older adults, put aging drinkers at special risk for developing cognitive decline and possibly dementia.

Fatty liver disease in persons with HIV infection

The leading cause of non-HIV-related mortality is liver disease. Fatty liver disease can be characterized as alcoholic or nonalcoholic in nature. Alcohol use is prevalent among individuals with HIV infection and can lead to medication nonadherence, lower CD4+ cell count, inadequate viral suppression, and disease progression. The pathogenesis of nonalcoholic fatty liver disease (NAFLD) in individuals with HIV infection includes metabolic syndrome, hyperuricemia, HIV-related lipodystrophy, genetic polymorphisms, medications, HIV itself, and the gut microbiome. The prevalence of NAFLD in persons with HIV infection ranges from 30% to 65% depending on the modality of diagnosis. Individuals with HIV infection and NAFLD are at higher risk of cardiovascular disease; however, there is a dearth of longitudinal outcomes studies on this topic. Current therapies for NAFLD, such as vitamin E and pioglitazone, have not been studied in persons with HIV infection. There are several drugs in phase II and III clinical trials that specifically target NAFLD in HIV, including CC chemokine receptor 5 inhibitors, growth hormone-releasing factor agonists, and stearoyl-CoA desaturase inhibitors. Persons with HIV should be screened for NAFLD while pursuing aggressive risk factor modification and lifestyle changes, given the increased risk of cardiovascular mortality.

Neutrophil-to-lymphocyte ratio can specifically predict the severity of hypertriglyceridemia-induced acute pancreatitis compared with white blood cell

Objectives

We aimed to evaluate the values of neutrophil‐to‐lymphocyte ratio (NLR) and white blood cell (WBC) in predicting severity of acute pancreatitis (AP) with different etiologies.

Methods

We compared NLR and WBC levels in patients with different etiologies and AP severity. The optimal cutoff value for them to predict severe acute pancreatitis (SAP) was determined by receiver operating characteristic (ROC) curve analysis.

Results

Both NLR and WBC were elevated in patients with SAP. After subgrouping AP by etiology, NLR was predictive of SAP only in hypertriglyceridemia‐induced AP (HTG‐AP), while WBC could effectively predict severity in both gallstone and HTG‐AP. The best cutoff value of WBC for predicting SAP in gallstone AP patients was 12.81 × 10⁹/L, with sensitivity and specificity of 78.9% and 70.2%. The best cutoff value for NLR and WBC to differentiate HTG‐SAP was more than 5.88 and 15.89 × 10⁹/L, respectively, with sensitivity and specificity of 87% and 50% for NLR and 56.5% and 75.76% for WBC.

Conclusions

Our study firstly demonstrated that NLR selectively played a role in HTG‐AP, while WBC could predict the severity of both gallstone and HTG‐AP. Furthermore, we firstly elucidated that NLR was more sensitive and accurate in judging the severity of HTG‐AP compared with WBC.

Fatty liver disease and the risk of erosive oesophagitis in the Korean population: a cross-sectional study

OBJECTIVES

To investigate an association between fatty liver disease (FLD) and erosive oesophagitis.

DESIGN AND SETTING

This was a cross-sectional study of subjects selected from examinees who underwent health check-up, including oesophagogastroduodenoscopy in one hospital between 2004 and 2011. Erosive oesophagitis was classified according to the Los Angeles classification and FLD was diagnosed with ultrasonography. The anthropometric and laboratory data of the subjects were analysed using χ² test and multivariate logistic regression. Additionally, we have analysed our data with two-stage least square estimation using the Baltagi-Chang one-way model to clarify unobserved confounding variable.

PRIMARY OUTCOME MEASURE

The effect of FLD on erosive oesophagitis.

RESULTS

Among the 14 723 eligible subjects, 4232 (28.7%) subjects diagnosed with FLD were classified into the fatty liver group and 10 491 (71.3%) subjects without FLD were classified into the non-fatty liver group. The incidence rate of erosive oesophagitis was significantly higher in the fatty liver group than in the non-fatty liver group (10.4%vs6.1%, p<0.0001). The multivariate analysis revealed that the fatty liver group was significantly associated with erosive oesophagitis (OR 1.19, 95% CI 1.03 to 1.37, p=0.016).

CONCLUSION

FLD diagnosed by ultrasonography is an independent risk factor of erosive oesophagitis. It suggests that FLD-related metabolic abnormality may be associated with erosive oesophagitis.

Alcoholic Pellagra as a Cause of Altered Mental Status in the Emergency Department

BACKGROUND

Pellagra, which is caused by a deficiency of niacin and tryptophan, the precursor of niacin, is a rare disease in developed countries where alcoholism is a major risk factor due to malnutrition and lack of B vitamins. Although pellagra involves treatable dementia and psychosis, it is often underdiagnosed, especially in developed countries.

CASE REPORT

In Japan, a 37-year-old man presented to the emergency department with altered mental status and seizures. Wernicke encephalopathy and alcohol withdrawal were suspected. The patient was treated with multivitamins, which did not include nicotinic acid amide, and oral diazepam. Despite medical treatment, his cognitive impairment progressively worsened, and eventually, pellagra was suspected. His response to treatment with nicotinic acid amide was substantial, and he was discharged without any long-term sequelae. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Despite the treatable dementia and psychosis, pellagra is often underdiagnosed, especially in developed countries and alcoholic patients. Pellagra should be routinely suspected in alcoholic patients because the response to appropriate treatment is typically dramatic.

Assessment of left ventricular function in chronic alcoholics by real-time three-dimensional echocardiography

Chronic alcohol consumption may lead to progressive cardiac dysfunction. The aim of this study was to evaluate the feasibility of using real-time 3-dimensional echocardiography (3DE) on assessing left ventricular (LV) function in chronic alcoholics.We classified 92 male alcoholics into mild, moderate, and severe groups; 30 age-matched controls were also recruited. LV end-diastolic volume (LVEDV), LV end-systolic volume (LVESV), LV ejection fraction (LVEF), LV mass (LVM), LV mass index (LVMI), and systolic dyssynchrony index (SDI) were measured by 3DE and 2-dimensional echocardiography (2DE).Compared to the control group, LV volume and mass were higher in the moderate and severe alcoholic groups (P < 0.05). The severe alcoholic (symptomatic) group demonstrated decreased LVEF and increased SDI (detected by 3DE) (P < 0.05).Real-time 3DE can detect the increases of LV volumes and mass in asymptomatic alcoholics, and the changes of LVEF and systolic synchrony index in symptomatic alcoholics.

Alcohol intoxication in non-motorised road trauma

OBJECTIVE

To determine the proportion of non-motorised road users involved in road traffic crashes that presents to hospital intoxicated.

METHODS

We undertook a retrospective cohort study using data collected from the Alfred Trauma Registry. All patients presenting to an adult major trauma centre in Victoria, Australia from July 2009 to June 2014 who were involved in a road traffic crash as a non-motorised road user - pedestrians, pedal-cyclists, non-motorised scooter users, horse riders - were included. Patients who had a blood alcohol measurement were included, and intoxication was defined as a blood alcohol concentration ≥0.05 g/100 mL.

RESULTS

There were 1323 patients included for analysis with data on presenting blood alcohol concentration. Alcohol was detected in 248 (18.7%; 95% CI: 16.7-20.9) patients, whereas 211 (15.9%; 95% CI: 14.1-18.0) were intoxicated. Among all included pedestrians, 161 (24.7%) were intoxicated; among all included pedal-cyclists, 47 (7.3%) were intoxicated. Intoxicated patients were significantly younger, and a higher proportion were males and more likely to present after hours and on public holidays (P < 0.01). Survival to hospital discharge and inpatient rehabilitation requirements were similar among intoxicated and non-intoxicated patients.

CONCLUSIONS

Intoxication was common among non-motorised road users, and the proportion of intoxicated patients in this subgroup appears unchanged over time despite public awareness programmes. The true burden of intoxication in non-motorised road users remains unknown because of a lack of routine testing. Legislation directed at testing for intoxication of non-motorised users and introduction of penalties should be considered to improve safety of all road users.

Inpatient healthcare utilisation in patients with alcoholic liver disease: what are the costs and outcomes?

BACKGROUND

Alcoholic liver disease (ALD) carries a significant cost burden and often leads to inpatient care. It is unclear whether inpatient care for ALD is any more costly than admission for other reasons.

AIMS

To compare the costs and outcomes of inpatient care for ALD to two groups: a control group of matched cases admitted in the same time frame and people admitted for other chronic liver diseases (CLD).

METHODS

All admissions for ALD and other CLD in a 3-month period were retrospectively identified. Five randomly identified gender- and age-matched contemporaneously admitted controls were allocated. Length of stay (LoS), mortality, inpatient costs, blood product utilisation and discharge destination were compared.

RESULTS

Of the 71 admissions due to CLD, ALD was the most frequent cause (53/71, 75%). ALD admissions cost more (median $10 100 vs $5294; P = 0.0012) and had greater LoS (median LoS 7.2 days (interquartile range (IQR) 0.2-40.7)) than controls (2.6 days (IQR 1.1-6.8); P = 0.0001). A larger proportion of the ALD cohort required blood transfusion and had a higher mortality than controls (24.5 vs 6.4%, P = 0.002 and 13.2 vs 0.2%; P < 0.0001 respectively). Self-discharge was more common in the ALD group (13.2 vs 1.1%, P < 0.0001).

CONCLUSIONS

ALD inpatient hospital admissions have greater median total cost, longer LoS, greater blood product utilisation, higher mortality and greater rate of discharge against medical advice than age- and gender-matched controls. These data emphasise the large inpatient care burden, high mortality and suboptimal engagement in those with ALD, which justifies the more active provision of services for ALD.

ANTI-INFLAMMATORY ACTIVITY OF PLATYCODIN D ON ALCOHOL-INDUCED FATTY LIVER RATS VIA TLR4-MYD88-NF-κB SIGNAL PATH

BACKGROUND

The current study was designed to evaluate the effect of Platycodin D (PD), triterpenoid saponins extracted from the roots of Platycodon grandiflorum (PG) on alcohol-induced fatty liver (AFL) and investigate the possible mechanism.

METHODS AND MATERIALS

A rat model was set up by feeding ethanol and fish oil to experimental rats, which then were treated with PD of 10, 20, 30 mg/kg body weight/day for 4 weeks, respectively, whereafter, liver function enzymes, endotoxin of serum and liver lipid were assayed by biochemical methods, cytokines, histochemistry of hepatic tissue, the protein expression of CD14 and TLR4, the mRNA expression of MD-2, MyD 88 and TRAF-6 were assayed.

RESULTS

Treatment with PD on AFL rats significantly decreased the levels of serum ALT, AST and TBIL, coefficient of liver index and the hepatic tissue contents of TG, additionally and dramatically decreased serum endotoxin levels, down-regulated MD-2 and CD14 levels, as well as the mRNA expression of TLR4, MyD88 and TRAF-6, accordingly suppressed NF-κB: p65 as well as endotoxin-mediated inflammatory factors such as TNF-α and IL-6.

CONCLUSIONS

Treatment with PD effectively protects against AFL through anti-inflammatory and anti-endotoxic process, and the confirmed mechanism is that PD treatment ameliorate alcoholic-induced liver injury mainly via TLR4-MyD88-NF-K: B signal path in AFL rat. List of Abbreviations: AFL: alcoholic-induced fatty liver, CD14: cluster of differentiation 14, LPS: lipopolysaccharide, LBP: lipopolysaccharide-binding protein, TLR4: toll-like receptor 4, MD-2: molecule myeloid differential protein-2, MyD 88: myeloid differentiation primary response protein 88, TRAF-6: TNF-receptor associated factor-6, NF-κB: nuclear transcription factor kappa B, IL-6: interleukin-6, TNF-α: tumor necrosis factor-α, PG: Platycodon grandiflorum, PD: Platycodin D.

CLIF-SOFA score and SIRS are independent prognostic factors in patients with hepatic encephalopathy due to alcoholic liver cirrhosis

Hepatic encephalopathy (HE) is a complication associated with worst prognosis in decompensated liver cirrhosis (LC) patients. Previous studies have identified prognostic factors for HE, and recent studies reported an association between systemic inflammatory response syndrome (SIRS) and liver disease. This study aimed to identify prognostic factors for 30-day mortality in alcoholic LC patients with HE who visited the emergency department (ED).This was a retrospective study of alcoholic LC patients with HE from January 1, 2010, to April 30, 2015. The baseline characteristics, complications of portal hypertension, laboratory values, Child-Pugh class, Model for End-stage Liver Disease (MELD) score, chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score, and SIRS criteria were assessed. The presence of 2 or more SIRS criteria was considered SIRS. The primary outcomes were 30-day mortality and prognostic factors for patients with HE visiting the ED.In total, 105 patients who met the inclusion criteria were analyzed. Overall, the 30-day mortality rate was 6.7% (7 patients).Significant variables were hepatorenal syndrome, international normalized ratio, white blood cell count, total bilirubin level, MELD score CLIF-SOFA score, and SIRS in univariate analysis. CLIF-SOFA score and SIRS were the significant factors in the multivariate analysis (hazard ratio 5.56, 15.98; 95% confidence interval 1.18-26.18, 1.58-161.37; P = 0.03, P = 0.02). The mortality rates differed according to the CLIF-SOFA score (P < 0.01).The CLIF-SOFA score and SIRS in alcoholic LC patients with HE visiting the ED are independent predictors of 30-day mortality.

Subjective parameters markedly limit the referral of transplantation candidates to liver transplant centres

BACKGROUND & AIMS

Equality of access to organ transplantation is a mandatory public health requirement. Referral from a local to a university hospital and then registration on the national waiting list are the two key steps enabling access to liver transplantation (LT). Although the latter procedure is well defined using the Model for End-stage Liver Disease score that improves equality of access, the former is mostly reliant on the practices of referring physicians. The aim of this study was to clarify the factors determining this initial step.

METHODS

This observational study included consecutive inpatients with cirrhosis of whatever origin in a cohort constituted between 2003 and 2008, using medical records and structured questionnaires concerning patient characteristics and the opinions of hospital clinicians. Candidates for LT were defined in line with these opinions.

RESULTS

Four hundred and thirty-three patients, mostly affected by alcoholic cirrhosis, were included, 21.0% of whom were considered to be candidates for LT. Factors independently associated with their candidature were: physician empathy [odds ratio (OR) = 10.8; 95% CI: 4.0-29.5], adherence to treatment (OR = 16.6; 95% CI: 3.7-75.2), geographical area (OR = 6.8; 95% CI: 2.2-21.3) and the patient's physiological age (OR = 2.3; 95% CI: 1.1-4.7).

CONCLUSIONS

Several subjective markers restrict the referral of patients from local hospitals to liver transplant centres. Their advancement to this second step is thus markedly weakened by initial subjectivity. The development of objective guidelines for local hospital physicians to assist them with their initial decision-making on LT is now necessary.

Subdural Hemorrhage, a Retrospective Review with Emphasis on a Cohort of Alcoholics

Subdural hemorrhage (SDH) is a common cause of death. As external evidence of injury may be absent, an autopsy is frequently needed to detect it. We conducted a 3-year review of SDH from the New York City Office of Chief Medical Examiner, with emphasis on a cohort of alcoholics. Our study population of 1942 included 1588 alcoholics. Of the alcoholics, c. 8% had SDH (26% of the total number of SDH). Of the alcoholics with SDH, 57% had associated brain injuries. As alcohol intoxication is frequently associated with aggressive and violent behavior, we are concerned that 6% of alcoholics in our review had no autopsy or imaging studies. It is possible that a portion of these may have had a SDH due to an unrecognized inflicted injury. We recommend that autopsies be performed on all alcoholics without a clear cause or mechanism of death.

Spleen size in cirrhosis of different etiologies

OBJECTIVES

The purpose of this study was to evaluate the impact of cirrhosis etiology on spleen size as measured by sonography and computed tomography (CT).

METHODS

The spleen images of 139 patients with cirrhosis secondary to alcohol abuse, hepatitis C, or nonalcoholic steatohepatitis were reviewed retrospectively. The maximum diagonal spleen length on a single sonogram and maximum spleen diameter on axial, coronal, or sagittal CT, whichever was largest, was compared among the etiologic groups.

RESULTS

In 127 patients who underwent sonography, the mean spleen size ± SD on sonography in the alcohol group (13.1 ± 2.5 cm) was significantly smaller than in the hepatitis C (15.0 ± 3.4 cm) and nonalcoholic steatohepatitis (15.2 ± 3.0 cm) groups (95% confidence intervals of the mean difference, 0.6 to 3.3 and 0.8 to 3.4 cm, respectively). In 87 patients who underwent CT, the mean spleen size on CT in the alcohol group (14.0 ± 2.7 cm) was smaller than in the hepatitis C (15.9 ± 3.4 cm) and nonalcoholic steatohepatitis (15.5 ± 3.6 cm) groups, but the difference was not statistically significant. The spleen sizes on both sonography and CT in 79 patients were strongly correlated (r = 0.88; P < .0001).

CONCLUSIONS

Spleen size in patients with cirrhosis varies by the etiology of the disease. Therefore, to apply spleen size as a diagnostic or prognostic criterion in this context, it is important to recognize that cutoff values derived from spleen size in one etiologic group may not produce the same results when extrapolated to another etiologic group.

De Novo Esophageal Carcinoma in Post-liver Transplant Patient

De novo esophageal malignancy following liver transplantation is very rare. Esophageal squamous cell carcinoma following liver transplant is closely associated with history of alcohol intake and tobacco chewing. We report on a 45-year-old man, chronic tobacco chewer and alcoholic who underwent liver transplantation for alcoholic cirrhosis and developed esophageal squamous cell carcinoma 23 months following the procedure. He was treated surgically and has had a tumor-free survival after 34 months of regular follow-up.

Zinc and liver disease

Zinc is an essential trace element required for normal cell growth, development, and differentiation. It is involved in DNA synthesis, RNA transcription, and cell division and activation. It is a critical component in many zinc protein/enzymes, including critical zinc transcription factors. Zinc deficiency/altered metabolism is observed in many types of liver disease, including alcoholic liver disease (ALD) and viral liver disease. Some of the mechanisms for zinc deficiency/altered metabolism include decreased dietary intake, increased urinary excretion, activation of certain zinc transporters, and induction of hepatic metallothionein. Zinc deficiency may manifest itself in many ways in liver disease, including skin lesions, poor wound healing/liver regeneration, altered mental status, or altered immune function. Zinc supplementation has been documented to block/attenuate experimental ALD through multiple processes, including stabilization of gut-barrier function, decreasing endotoxemia, decreasing proinflammatory cytokine production, decreasing oxidative stress, and attenuating apoptotic hepatocyte death. Clinical trials in human liver disease are limited in size and quality, but it is clear that zinc supplementation reverses clinical signs of zinc deficiency in patients with liver disease. Some studies suggest improvement in liver function in both ALD and hepatitis C following zinc supplementation, and 1 study suggested improved fibrosis markers in hepatitis C patients. The dose of zinc used for treatment of liver disease is usually 50 mg of elemental zinc taken with a meal to decrease the potential side effect of nausea.

Broncho-Oesophageal Fistula (BOF) Secondary to Missing Partial Denture in an Alcoholic in a Low Resource Country

The clinical course of a missing partial denture with secondary BOF in an alcoholic is presented. In the index case we report an exceptional clinical course of a patient who did not ascribe his symptoms to his ''missing'' dentures for several years, the odontologist who replaced an unrecovered denture, and the generalist who administered the barium swallow in an unsuspected BOF. Preoperative optimization of the patient was by blenderized local feeds through a feeding tube gastrostomy and by chest physiotherapy. Extraction of the denture and closure of fistula were done through a right thoracotomy. The importance of a high index of clinical suspicion of BOF in a low resource setting to avoid the morbidity and mortality associated with missing dentures is discussed. Odontologists, caregivers and clinicians must educate patients on the hazards of missing dentures and cases of missing / lost dentures should be adequately investigated / explored in the patient's history and clinical assessment before they are replaced.

Relationship between dietary beef, fat, and pork and alcoholic cirrhosis

Nanji and French investigated the relationship between per-caput consumption of total fat, beef, and pork and for alcohol consumption and rates of mortality for cirrhosis for 16 countries for 1965. The present study reports significant and positive associations for 1996 and 2003 between the following: alcohol consumption and cirrhosis mortality, pork consumption and cirrhosis mortality, the product of alcohol and pork consumption and the product of alcohol and fat consumption. These supportive associations may represent a relationship between the risk of alcoholic cirrhosis and some heretofore unknown dietary or environmental factor related to conditions of pork or fat consumption. Limitations of the study design are discussed.

Similarities and differences in the pathogenesis of alcoholic and nonalcoholic steatohepatitis

Subpopulations of individuals with alcohol-induced fatty livers and nonalcoholic steatosis develop steatohepatitis. Steatohepatitis is defined histologically: increased numbers of injured and dying hepatocytes distinguish this condition from simple steatosis. The increased hepatocyte death is generally accompanied by hepatic accumulation of inflammatory cells and sometimes increases in myofibroblastic cells, leading to hepatic fibrosis and eventually, cirrhosis. The purpose of this review is to summarize similarities and differences in the pathogenesis of steatohepatitis in alcoholic fatty liver disease and nonalcoholic fatty liver disease.

Treatment of alcoholic liver disease

Alcoholic liver disease (ALD) remains a major cause of morbidity and mortality worldwide. For example, the Veterans Administration Cooperative Studies reported that patients with cirrhosis and superimposed alcoholic hepatitis had a 4-year mortality of >60% (worse than many common cancers such as breast and prostate). The cornerstone for therapy for ALD is lifestyle modification, including drinking cessation and treatment of decompensation, if appropriate. Nutrition intervention has been shown to play a positive role on both an in-patient and out-patient basis. Corticosteroids are effective in selected patients with alcoholic hepatitis, and treatment with pentoxifylline appears to be a promising anti-inflammatory therapy. Recent studies have indicated anti-TNFalpha therapy, at least for alcoholic hepatitis. Some complementary and alternative medicinal agents, such as milk thistle and S-adenosylmethionine, may be effective in alcoholic cirrhosis. Treatment of the complications of ALD can improve the quality of life and, in some cases, decrease short-term mortality.

Cortical gray matter loss in treatment-naïve alcohol dependent individuals

BACKGROUND

Most studies of the impact of alcohol dependence on the brain have examined individuals in treatment. Such samples represent a small proportion of alcoholics in the general population. Such samples may embody a bias (Berkson's fallacy) if the association between variables (for example, alcoholism and cortical gray matter loss) differs between the population of alcoholics in treatment and alcoholics in the general population. Our objective was to determine if treatment-naïve alcoholics show structural brain changes versus controls and to compare our findings with reports evaluating alcoholic samples drawn from treatment populations.

METHODS

Structural MRI was used to assess whole brain and regional volumes of cortical gray matter and white matter in 24 young to middle-aged treatment-naïve alcohol-dependent males versus 17 controls.

RESULTS

Cortical gray matter volumes in alcohol-dependent individuals were negatively associated with age and lifetime duration of alcohol use (which were highly confounded). These subjects showed reduced whole brain (p < 0.05), prefrontal (p < 0.01), and parietal (p < 0.05) cortical gray matter compared with controls. White matter and temporal cortex, tissues that usually show volume reductions in samples drawn from treatment, did not differ between treatment-naïve alcoholics and controls (all p > 0.40).

CONCLUSIONS

Our findings are consistent with the hypothesis that structural brain changes in treatment-naïve alcoholics are less severe than those reported in clinical samples of alcoholics, perhaps due to less concomitant psychopathology and a reduced severity of alcoholism in treatment-naïve alcoholics. However, caution must be taken when comparing our findings with results from clinical samples, as we did not directly compare treatment-naïve alcoholics with treated alcoholics and our treatment-naïve sample tended to be younger than the (clinical) samples reported in the literature. Nevertheless, we suggest that most of the reports of the central nervous system consequences of alcoholism may not accurately describe the majority of alcoholic-dependent individuals.
