This prospective, multicentre study was conducted between September and October 2003 in 38 French departments of internal medicine, infectious disease and hepatogastroenterology and included 406 consecutive HBV-infected patients (positive HBsAg), half of whom were HIV-infected (53%). The aim was to outline the main characteristics of hepatitis B virus (HBV)-human immunodeficiency virus (HIV) co-infected patients in French hospitals. HBV-HIV co-infected patients (85% were receiving HAART; mean CD4 count 447±245/μl, HIV RNA load <400 copies/ml, 67% of patients), compared to HIV-negative patients, were more often male, injecting drug users, HBeAg-positive and HCV-HIV co-infected (P<10−4). They underwent liver biopsy less often (31% vs. 51%, P<10−4), particularly those with severe immunodeficiency. They received anti-HBV treatment more often (75% vs. 45·7%, P<10−4), mainly lamivudine and tenofovir. Significant improvements in the management of such patients are awaited mainly in the appraisal of liver disease by either liver biopsy or non-invasive alternatives to liver biopsy.

<b><i>Background:</i></b> Although transmission of pathogenic viruses through human tissue grafts is rare, it is still one of the most serious dreaded risks of transplantation. Therefore, in addition to the detailed medical and social history, a comprehensive serologic and molecular screening of the tissue donors for relevant viral markers for human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) is necessary. In the case of reactive results in particular, clear decisions regarding follow-up testing and the criteria for tissue release must be made. <b><i>Methods:</i></b> Based on the clinical relevance of the specific virus markers, the sensitivity of the serological and molecular biological methods used and the application of inactivation methods, algorithms for tissue release are suggested. <b><i>Results:</i></b> Compliance with the preanalytical requirements and assessment of a possible hemodilution are mandatory requirements before testing the blood samples. While HIV testing follows defined algorithms, the procedures for HBV and HCV diagnostics are under discussion. Screening and decisions for HBV are often not as simple, e.g., due to cases of occult HBV infection, false-positive anti-HBc results, or early window period positive HBV NAT results. In the case of HCV diagnostics, modern therapies with direct-acting antivirals, which are often associated with successful treatment of the infection, should be included in the decision. <b><i>Conclusion:</i></b> In HBV and HCV testing, a high-sensitivity virus genome test should play a central role in diagnostics, especially in the case of equivocal serology, and it should be the basis for the decision to release the tissue. The proposed test algorithms and decisions are also based on current European recommendations and standards for safety and quality assurance in tissue and cell banking.

Since the inception of flexible fiberoptic endoscopes, disinfection of these instruments has been a problem. Soaking in glutaraldehyde does not always achieve sterilization, and often damages the scopes. Ethylene oxide can sterilize endoscopes; however, it is economically impractical because of a required downtime of 24 hours. Thus, it is obvious, especially with respect to human immunodeficiency virus, hepatitis B virus, and Mycobacterium, that a new technique to attain sterility is necessary. This paper discusses a new method of sterile introduction of the flexible nasopharyngolaryngoscope. The technique employs disposable sterile sheaths that are prepackaged and made from a thermoplastic elastomer with a clear optical end. The sheaths can be applied in seconds and tightly adhere to the flexible insertion portion of the scope. Results to date indicate that the performance of the endoscope is unhindered by using the sheaths. Furthermore, there has been no break in the integrity of the sheaths or damage to instruments. It is our opinion that these devices will greatly improve the level of sterility while at the same time reducing costs and downtime.
