Genotyping using 5'noncoding (5'NC) sequencing was performed. We compared categorical data using the Fisher's exact F-test and odds ratios (OR) were calculated for evaluating association of HCV genotype and risk factors.RESULTS: The sex ratio was predominantly male (2.2) and individuals aged less than 40 years represented 49.6% of the population. Genotype 1 was predominant (53.4%) followed by genotype 3 (33%). Among risk factors, intravenous drug usage (IVDU) was the most frequently reported (71.4%) followed by medical-related transmission (17.6%) including haemophilia, transfusion recipients and other nosocomial reasons. Genotype 3 was significantly associated to IVDU (OR = 4.84, P 〈 0.0001) whereas genotype 1 was significantly associated with a medical procedure (OR = 2.42, P 〈 0.001). The HCV genotype distribution from inmate patients differed significantly from the rest of the population (Chi-square test with four degrees of freedom, P 〈 0.0001) with a higher frequency of genotype 3 (46.5% vs 27.5%) and a lower frequency of genotype 1 and 4 (44.7% vs 56.8% and 5.3% vs 9.6%, respectively). IVDU was nearly exclusively reported as a risk factor in prison.CONCLUSION: We report the first description of the HCV genotype distribution in Luxembourg. The repartition is similar to other European counties, with one of the highest European prevalence rates of genotype 3 (33%). Since serology screening became available in 2992, IVDU remains the most common way of HCV transmission in Luxembourg.展开更多

Methods: The related case reports published in periodicals published from 1949 to 2006 were analyzed with the bibliometrics method. Possibility on safety assessment of Chinese materia medica was discussed as well with the method of link analysis. Results: The total number of the tonics selected for the present study was 101, including 44 single drugs and 46 set prescriptions with adverse drug reactions (ADR) found in these tonics. It was found that ADR of 10 single drugs and 29 preparations were not specified in authoritative Chinese materia medica monographs. Among all the set prescriptions, the problem of injection has been standing on the top. Statistical analysis on single factor demonstrates that the most frequently referred ADR come from drug abuse (accounting for 29.20%), and overdose (24.54%). Conclusion: The safety problem of injection remains in a trend of robust growth at least for a period of time, thus reappraisal of the safety issue for the tonics of injection is imperative. It is essential for the public to take doctor’s advice to guarantee safe administration of the tonics, especially for the patients with allergic constitution or those suffering from the liver and heart diseases.展开更多
