Alcohol intoxication impairs neutrophil function and increases host susceptibility to Streptococcus pneumoniae. In a rat model of pneumonia, the effects of acute intoxication were monitored for lung chemokine responses, neutrophil recruitment, and bactericidal activity. Alcohol delayed lung neutrophil recruitment, increased bacterial burden, and decreased survival. Before neutrophil recruitment, bronchoalveolar lavage (BAL) macrophage inflammatory protein-2 (MIP-2) and cytokine-induced neutrophil chemoattractant (CINC) were decreased by alcohol. This alcohol-induced effect was reversed at 6 h, when there were large numbers of neutrophils in control BAL fluid, compared with the alcohol-treated group. Cyclophosphamide-induced neutropenia decreased neutrophil recruitment, minimizing the effects of recruited neutrophils on chemokine levels, and extended the alcohol-induced chemokine suppression. MIP-2 and CINC mRNA contents also were suppressed by alcohol 4 and 6 h after infection. Thus, alcohol suppresses lung chemokine activity in response to S. pneumoniae, which is associated with delayed neutrophil delivery, elevated bacterial burden, and increased mortality.
This study presents the test results of blood and urine samples of impaired drivers in the Netherlands between January 1995 and December 1998. In this period, the blood alcohol concentrations of 11,458 samples have been determined and 1665 blood or urine samples have been analysed for drugs. The median alcohol concentration was between 1.7 and 1.8 mg/ml blood. In 80% of the 1665 analysed samples drugs were detected. At least 42% (702/1665) of the impaired drivers were poly-drug users, with cocaine present in the most frequent combinations. In the Netherlands, the procedure to prove driving under the influence is complex. This procedure can be made more efficient and more effective by embedding the analytical test results, needed to prosecute an impaired driver, in the law. In Belgium and Germany, such laws already are in force. If we would apply the qualifications of the new Belgian law on our analytical data, 67% of the impaired drivers included in this comparison could have been prosecuted without discussion in court.
