Markers Of Inflammation And Mortality In A Cohort Of Patients With Alcohol Dependence

Inflammation and intestinal permeability are believed to be paramount features in the development of alcohol-related liver damage. We aimed to assess the impact of 3 surrogate markers of inflammation (anemia, fibrinogen, and ferritin levels) on mid-term mortality of patients with alcohol dependence. This longitudinal study included patients with alcohol dependence admitted for hospital detoxification between 2000 and 2010. Mortality was ascertained from clinical charts and the mortality register. Associations between markers of inflammation and all-cause mortality were analyzed with mortality rates and Cox proportional hazards regression models. We also performed a subgroup analysis of mortality rates in patients with anemia, based on their mean corpuscular volume (MCV). We included 909 consecutive patients with alcohol dependence. Patients were mostly male (80.3%), had a median age of 44 years (interquartile range [IQR]: 38-50), and upon admission, their median alcohol consumption was 192 g/day (IQR: 120-265). At admission, 182 (20.5%) patients had anemia; 210 (25.9%) had fibrinogen levels > 4.5 mg/dL; and 365 (49.5%) had ferritin levels > 200 ng/mL. At the end of follow-up (median 3.8 years [IQR: 1.8-6.5], and a total of 3861.07 person-years), 118 patients had died (12.9% of the study population). Cox regression models showed that the presence of anemia at baseline was associated with mortality (hazard ratio [HR]: 1.67, 95% confidence interval [CI]: 1.11-2.52, P< 0.01); no associations were found between mortality and high fibrinogen or high ferritin levels. A subgroup of patients with anemia was analyzed and compared to a control group of patients without anemia and a normal MCV. The mortality ratios of patients with normocytic and macrocytic anemia were 3.25 (95% CI: 1.41-7.26; P< 0.01) and 3.39 (95% CI: 1.86-6.43; P< 0.01), respectively. Patients with alcohol dependence admitted for detoxification had an increased risk of death when anemia was present at admission. More accurate markers of systemic inflammation are needed to serve as prognostic factors for poor outcomes in this subset of patients

Hepatitis C infection substantially reduces survival of alcohol-dependent patients

Background: Heavy alcohol use is associated with life-threatening complications including progressive liver disease. We aimed to analyze the impact of hepatitis C virus (HCV) infection on survival and liver-related death in alcohol-dependent patients. Patients and methods: This is a longitudinal study in patients seeking treatment of alcohol abuse between 2000 and 2010. Information on alcohol use characteristics, alcoholic liver disease, and HCV infection were obtained at entry. Cumulated mortality and causes of death were ascertained through clinical records and death registry. Results: A total of 819 patients (81.6% men) underwent ethanol detoxification; age was 44 (interquartile range [IQR] 38-51) years; the duration of heavy alcohol use was 14 (IQR 6-24) years; and the alcohol consumption was 190 (IQR 120-250) g/day. The prevalence of HCV infection was 15.8%. There were 129 (16.9%) deaths during 5,117 persons-year (p-y) of follow-up (median follow-up 6.4 [IQR 4.3-9.2] years); 31 (24.6%) deaths were observed among the HCV-positive patients, and 98 (15.4%) deaths were observed among the HCV-negative patients. The mortality rate was significantly (P=0.03) higher among the HCV-positive patients (3.84x100 p-y; 95% confidence interval [CI]: 2.70, 5.46) than among the HCV-negative patients (2.27x100 p-y; 95% CI: 1.86, 2.77). Survival times for the HCV infected patients were 34% shorter (time ratio relative to HCV negative: 0.66; 95% CI: 0.51,0.86). The main causes of death in the HCV-positive and -negative patients were liver-related mortality (48.4%) and neoplasia (22.4%), respectively. The liver-related mortality was significantly higher among the HCV-positive patients (adjusted sub-distribution hazard ratio [asHR] 3.65; 95% CI: 1.72, 7.78; P=0.001). Conclusion: HCV infection compromises the survival of patients with alcohol abuse/dependence. The new direct antiviral agents for the treatment of HCV infection may result in better clinical outcomes

Liver Ultrasound Abnormalities in Alcohol Use Disorder

Alcohol-related liver disease is the most common alcohol-related medical illness, and it is the major driver of liver-related deaths worldwide. However, no screening guidelines currently exist for the early detection of liver disease in patients with risky drinking or those with alcohol use disorder. Moreover, most patients with alcohol-related liver fibrosis, which is the main prognostic factor of progression to end-stage liver disease, have normal blood tests. Abdominal ultrasound is a cheap and readily available diagnostic procedure that is rarely used in patients with alcohol use disorder without overt liver disease. In addition, abdominal ultrasound can detect other forms of liver disease, which are not uncommon in patients with unhealthy alcohol use, and can have a negative impact on the natural history of alcohol-related liver disease. In this chapter we will review the current knowledge about the use of liver ultrasound in patients with alcohol use disorder for the early detection of alcohol-related liver disease, as well as the potential use to detect other forms of liver disease. We will also briefly discuss other methods for the noninvasive detection of liver steatosis and/or liver fibrosis in patients with alcohol use disorder

Long-Term Mortality of Patients with an Alcohol-Related Wernicke-Korsakoff Syndrome

Aims: To characterize a series of contemporary patients with alcohol-related Wernicke's encephalopathy (WE) or Korsakoff's syndrome (KS) and to update the current prognosis of disease. Methods: Retrospective and prospective study of patients diagnosed with an alcohol-related WE or KS between 2002 and 2011 in a tertiary hospital. Socio-demographic, alcohol use characteristics, signs and symptoms, co-morbidity and blood parameters were obtained at admission. Patients were followed up until 2013 and causes of death were ascertained through the review of charts. Results: Sixty-one patients were included (51 with WE and 10 with KS). Among patients with WE, 78% were men and age at diagnosis was 57 years (interquartile range (IQR): 49-66). Twenty-three percent fulfilled the classic WE triad. Regarding Caine's criteria for WE, 70.6% presented with at least two out of four signs or symptoms. Median follow-up of patients with WE syndrome was 5.3 years (IQR: 2.6-8.8), the cumulated mortality was 45% and death rate of 7.4 × 100 person-years (95% confidence interval (CI): 4.8-10.9). Overall, 50% of patients would be expected to die within 8 years of WE episode and main causes of death included serious bacterial infections (44.5%) and cancer (33.3%). Conclusions: Survival of patients with an alcohol-related Wernicke-Korsakoff syndrome is poor; pursuing treatment of alcohol use disorder and early diagnosis of thiamine deficiency is a priority for improving clinical outcome

Markers of inflammation and mortality in a cohort of patients with alcohol dependence

Sex-specific disease outcomes of HIV-positive and HIV-negative drug users admitted to an opioid substitution therapy program in Spain : a cohort study

Altres ajuts: We would like to thank the health care professionals working at CASDelta-Badalona, the mobile unit (Methadone Bus), and pharmaciesdispensing methadone in Badalona and Santa Coloma de Gramenet. This work has been made possible by the collaboration of the MortalityRegister, Institute of Health Studies, Department de Salut, Generalitat de Catalunya.Opioid substitution therapy has improved the survival of heroin users with and without HIV infection. We aimed to analyze sex differences in mortality rates and predictors of death among those admitted to a methadone treatment program (MTP). Longitudinal study of patients enrolled in a MTP from 1992 to 2010. Socio-demographic and drug use characteristics, and markers of viral infections were assessed at entry. Vital status was ascertained by clinical charts and the mortality register. Four calendar periods were defined according to the introduction of preventive and treatment interventions in Spain. Predictors of death were analyzed by Cox regression models. 1,678 patients (82.8% men) were included; age at first heroin use was 18.6 years (IQR: 16-23 years), and age at first entry into a MTP was 30.7 years (IQR: 26-36 years). A total of 441 (26.3%) deaths occurred during 15,124 person-years (p-y) of follow-up (median: 9.2 years, IQR: 4-13 years). HIV infection was the main predictor of death in men (HR = 3.5, 95% CI: 2.1-5.7) and women (HR = 3.2, 95% CI: 1.2-8.7) and main cause of death was HIV/AIDS. Overall mortality rate was 2.9 per 100 p-y (95% CI: 2.7-3.2 per 100 p-y) and death rates decreased over time: 7.4 per 100 p-y (95% CI: 6.3-8.8 per 100 p-y) for the 1992-1996 period to 1.9 per 100 p-y (95% CI: 1.6-2.4 per 100 p-y) for the 2007-2010 period. In women, a slightly increase in mortality was observed in recent periods specifically among HIV-positive women (3.7 per 100 p-y in period 2002-2006 and 4.5 per 100 p-y in 2007-2010). Significant reductions in mortality of patients in MTP are observed after nineteen years of observation. However, HIV infection shows a great impact on survival, particularly among HIV-infected women.

Molecular and morphological diversity in the /Rhombisporum clade of the genus Entoloma with a note on E. cocles

A combined morphological and molecular genetic study of the European species within the /Rhombisporum clade of the genus Entoloma reveals a high species diversity. This group comprises typical grassland species with pronounced and welldifferentiated cheilocystidia, and a wide range of spore shapes varying from rhomboid to five-angled. To fix the concept of the classical species E. rhombisporum, a neotype is designated. Nine species are described as new to science based on the result of nrDNA ITS phylogeny with additional gap coding, and morphological characterization: E. caulocystidiatum, E. lunare, E. pararhombisporum, E. pentagonale, E. perrhombisporum, E. rhombiibericum, E. rhombisporoides, E. sororpratulense, and E. subcuboideum. The ITS sequences of the holotypes of previously described species belonging to the /Rhombisporum clade, viz., E. laurisilvae and E. pratulense have also been generated and are published here for the first time. Since many of the above-mentioned species have been misidentified as E. cocles, it seemed opportune to also study this species and to designate a neotype to fix its current concept. A key including European species is presented. As most of the species are potentially important indicators for threatened grassland communities, the 130 ITS barcodes newly generated for this study may be useful as a reference in conservation and metabarcoding projects.
