Number of hospital contacts with alcohol problems predicts later risk of alcoholic liver cirrhosis.

AIMS: Alcoholic liver cirrhosis is usually preceded by years of heavy drinking. We investigated whether the risk of alcoholic liver cirrhosis increases as the number of hospital contacts with alcohol problems goes up. METHODS: This was a supplementary analysis on a nationwide register-based cohort study. All patients in Denmark with an initial hospital contact with alcohol problems (alcohol intoxication, harmful alcohol use or alcohol dependence) 1998-2002, free of liver disease, were followed for diagnosis of alcoholic liver cirrhosis. The number of subsequent hospital contacts with alcohol problems was estimated as a time-dependent variable for each patient. RESULTS: In all, 36,044 hospital patients with an initial hospital contact with alcohol problems were included. These patients had 301,525 subsequent hospital contacts with alcohol problems. Risk of alcoholic liver cirrhosis increased ( p < 0.0001) with number of alcohol hospital contacts in both men and women for up to nine contacts. CONCLUSIONS: The number of prior hospital contacts with alcohol problems might provide clinicians with a helpful metric in deciding whether to offer preventive interventions for alcoholic liver cirrhosis

Hospital contacts with alcohol problems prior to liver cirrhosis or pancreatitis diagnosis.

AIM: To evaluate prior hospital contacts with alcohol problems in patients with alcoholic liver cirrhosis and pancreatitis. METHODS: This was a register-based study of all patients diagnosed with alcoholic liver cirrhosis or pancreatitis during 2008-2012 in Denmark. Hospital contacts with alcohol problems (intoxication, harmful use, or dependence) in the 10-year period preceding the diagnosis of alcoholic liver cirrhosis and pancreatitis were identified. RESULTS: In the 10 years prior to diagnosis, 40% of the 7719 alcoholic liver cirrhosis patients and 40% of the 1811 alcoholic pancreatitis patients had at least one prior hospital contact with alcohol problems. Every sixth patient (15%-16%) had more than five contacts. A similar pattern of prior hospital contacts was observed for alcoholic liver cirrhosis and pancreatitis. Around 30% were diagnosed with alcohol dependence and 10% with less severe alcohol diagnoses. For the majority, admission to somatic wards was the most common type of hospital care with alcohol problems. Most had their first contact with alcohol problems more than five years prior to diagnosis. CONCLUSION: There may be opportunities to reach some of the patients who later develop alcoholic liver cirrhosis or pancreatitis with preventive interventions in the hospital setting

Multi-centre evaluation of the speed-oligo Mycobacteria assay for differentiation of Mycobacterium spp. in clinical isolates

<p>Abstract</p> <p>Background</p> <p>A new DNA line probe assay (Speed-oligo Mycobacteria, Vircell) has been launched for rapid differentiation of <it>Mycobacterium </it>spp. from cultures. Compared to other line-probe assays, Speed-oligo Mycobacteria covers a relatively limited spectrum of species but uses a simpler and faster dip-stick technique. The present multi-centre, multi-country study aimed at evaluating the utility and usability of Speed-oligo Mycobacteria in routine mycobacteriology diagnostics. Results from Speed-oligo Myobacteria were compared to those from Genotype CM (HAIN lifescience, Nehren, Germany), another line-probe assay.</p> <p>Methods</p> <p>Speed-oligo Mycobacteria assay was performed in three main steps: 1) DNA extraction from cultured material 2) PCR amplification of the target gene and an internal control and 3) hybridization of the PCR products to specific probes by means of a dip-stick.</p> <p>Results</p> <p>Two hundred forty-two clinical isolates were recovered from consecutive positive mycobacterial cultures at two German (IML Gauting, Bioscientia Ingelheim), one Czech (KLINLAB Prague), and at a Sudanese (Khartoum) laboratory. All <it>Mycobacterium </it>species covered by the assay were reliably recognized. The rate of false positive results was 1.2% and concerned only the species <it>M. marinum </it>and <it>M. peregrinum</it>. The identification rate, i.e. the proportion of isolates which was correctly differentiated to the level of species or complex by the assay, differed significantly among laboratories being 94.9%, 90.7%, and 75.0% at the study sites IML Gauting, KLINLAB Prague and Bioscientia Ingelheim, respectively. This difference was caused by different spectra of NTM species encountered by the laboratory centres in daily routine diagnostics.</p> <p>Conclusions</p> <p>Speed-oligo Mycobacteria assay was proved a rapid and easy-to-perform alternative to conventional line-probe assays. The assay showed excellent sensitivity with regard to identification of genus <it>Mycobacterium </it>and species/complexes covered by the test. However, due to its relatively limited spectrum of taxa, a varying proportion of NTM may not be identified by the assay in daily diagnostics demanding further analyses. The only significant shortcoming in terms of specificity was the misidentification of the clinically relevant species <it>M. marinum</it>.</p

Hospital admissions and mortality in the 15 years after a first-time hospital contact with an alcohol problem: a prospective cohort study using the entire Danish population.

BACKGROUND: Potential benefits of preventing continued alcohol intake in individuals presenting at the hospital with an alcohol problem can be highlighted by studying their excess risk of subsequent morbidity and mortality. METHODS: All Danish residents with a first-time hospital contact with alcohol problems (intoxication, harmful use or dependence) in 1998-2002 were followed through 2012 using healthcare registries. We compared their cause-specific rates of hospital admission and mortality to the expected rates derived from the general population by calculating standardized incidence rate ratios. RESULTS: The 26 716 men and 12 169 women who were hospitalized with alcohol problems (median age 44 years) had more than 10 times the rate of subsequent admission to psychiatric departments and three times the rate of subsequent admission to somatic departments compared with the general population. In particular, the hospital admission rates for gastroenterological disease and injuries were high. The cumulative all-cause 10-year mortality risk was 29% [95% confidence interval (CI), 28-30] in men and 26% (95% CI, 24-27) in women with alcohol problems. The ratios of observed to expected death rate for all-cause mortality were 4.0 (95% CI, 3.8-4.1) in men and 4.3 (95% CI, 4.0-4.7) in women and, for causes of death fully attributable to alcohol, 16 (95% CI, 15-17) in men and 33 (95% CI, 29-38) in women. CONCLUSIONS: Individuals hospitalized with alcohol problems have much higher rates of subsequent alcohol-related hospital admission and mortality than the general population. Increased focus on preventing continued alcohol consumption in these individuals may reduce their subsequent morbidity and mortality

Serovars of Mycobacterium avium complex isolated from patients in Denmark.

Danish isolates of Mycobacterium avium complex were serotyped by the use of seroagglutination. The most prevalent serovars among patients with AIDS (n = 89) were 4 and 6, while among non-AIDS patients the most prevalent serovars were 1, 6, and 4, with no major differences between those in patients with pulmonary disease (n = 65) and those in patients with lymph node infection (n = 58). The results suggest a Scandinavian distribution of serovars with a predominance of serovar 6 and fail to demonstrate any selective protection against different serovars by Mycobacterium bovis BCG vaccination

Risk for alcoholic liver cirrhosis after an initial hospital contact with alcohol problems: A nationwide prospective cohort study.

Alcoholic liver cirrhosis is usually preceded by many years of heavy drinking, in which cessation in drinking could prevent the disease. Alcohol problems are not consistently managed in hospital patients. We followed all Danish patients with an initial hospital contact with alcohol problems (intoxication, harmful use, or dependence) during 1998-2002 for alcoholic liver cirrhosis development (n = 36,044). In this registry-based cohort, we identified predictors of the absolute risk for alcoholic liver cirrhosis. Incidence rate ratios (IRRs) were estimated as the incidence rate of alcoholic liver cirrhosis in these patients relative to the general population. Age and alcohol diagnosis were significant predictors of alcoholic liver cirrhosis risk in men and women, whereas civil status, education, and type of hospital care were not. In men, the 15-year absolute risk was 0.7% (95% confidence interval [CI], 0.4, 0.8) for 20-29 years, 5.5% (95% CI, 4.9, 6.2) for 30-39 years, 9.8% (95% CI, 9.0, 11) for 40-49 years, 8.9% (95% CI, 8.1, 9.8) for 50-59 years, 6.2% (95% CI, 5.1, 7.2) for 60-69 years, and 2.5% (95% CI, 1.7, 3.3) for 70-84 years. According to alcohol diagnosis in men, the 15-year absolute risk was 2.6% (95% CI, 2.3, 2.9) for intoxication, 7.7% (95% CI, 6.4, 7.9) for harmful use, and 8.8% (95% CI, 8.2, 9.4) for dependence. The IRR for alcoholic liver cirrhosis in the cohort relative to the general population was 11 (95% CI, 10, 12) in men and 18 (95% CI, 15, 21) in women. CONCLUSION: Hospital patients with alcohol problems had a much greater risk for alcoholic liver cirrhosis compared to the general population. The risk was particularly increased for patients 40-59 years and for patients diagnosed with harmful use or dependence. (Hepatology 2017;65:929-937)
