Weltweiter SARS-Alarm : eine neue Seuche auf dem Vormarsch?

Mitte März 2003 löste die WHO einen weltweiten Alarm aus, nachdem sich eine neuartige, schwere und unter bestimmten Umständen hochansteckende Atemwegserkrankung scheinbar unaufhaltsam über weite Teile der Welt auszubreiten schien. Am 15. März desselben Jahres landeten die ersten Patienten mit Verdacht auf Schweres Akutes Respiratorisches Syndrom (SARS) in Frankfurt und wurden auf die Isolierstation des Universitätsklinikums aufgenommen. Auslöser war ein zuvor nicht bekanntes Coronavirus, das heute als SARS-CoV bezeichnet wird. Derzeit laufen Untersuchungen zur Biologie und Epidemiologie des neuen Erregers, zu antiviralen Hemmstoffen sowie zu Desinfektions- und Inaktivierungsmöglichkeiten und neuen Therapieoptionen. Daneben wird analysiert, wie sich das öffentliche Gesundheitswesen auf eine mögliche Wiederkehr vorbereiten muss. SARS ist ein Beispiel dafür, wie schnell sich eine Infektionskrankheit in der modernen Welt international ausbreiten kann und wie wichtig in einem solchen Falle eine gut koordinierte internationale Kooperation ist.

Virological and immunological response to three boosted protease inhibitor regimens

Poster presentation: Purpose of the study To compare the virological, immunological and clinical response to three boosted double protease inhibitor (PI) regimens of saquinavir and ritonavir in combination with lopinavir (LOPSAQ), atazanavir (ATSAQ) or fosamprenavir (FOSAQ) without reverse transcriptase inhibitors (RTI) in HIV-positive patients with limited RTI treatment options. ..

Isolation facilities for highly infectious diseases in Europe - A cross-sectional analysis in 16 countries

BACKGROUND: Highly Infectious Diseases (HIDs) are (i) easily transmissible form person to person; (ii) cause a life-threatening illness with no or few treatment options; and (iii) pose a threat for both personnel and the public. Hence, even suspected HID cases should be managed in specialised facilities minimizing infection risks but allowing state-of-the-art critical care. Consensus statements on the operational management of isolation facilities have been published recently. The study presented was set up to compare the operational management, resources, and technical equipment among European isolation facilities. Due to differences in geography, population density, and national response plans it was hypothesized that adherence to recommendations will vary. METHODS AND FINDINGS: Until mid of 2010 the European Network for Highly Infectious Diseases conducted a cross-sectional analysis of isolation facilities in Europe, recruiting 48 isolation facilities in 16 countries. Three checklists were disseminated, assessing 44 items and 148 specific questions. The median feedback rate for specific questions was 97.9% (n = 47/48) (range: n = 7/48 (14.6%) to n = 48/48 (100%). Although all facilities enrolled were nominated specialised facilities' serving countries or regions, their design, equipment and personnel management varied. Eighteen facilities fulfilled the definition of a High Level Isolation Unit'. In contrast, 24 facilities could not operate independently from their co-located hospital, and five could not ensure access to equipment essential for infection control. Data presented are not representative for the EU in general, as only 16/27 (59.3%) of all Member States agreed to participate. Another limitation of this study is the time elapsed between data collection and publication; e.g. in Germany one additional facility opened in the meantime. CONCLUSION: There are disparities both within and between European countries regarding the design and equipment of isolation facilities. With regard to the International Health Regulations, terminology, capacities and equipment should be standardised

Cohort Profile: Antiretroviral Therapy Cohort Collaboration (ART-CC)

The advent of effective combination antiretroviral therapy (ART) in 1996 resulted in fewer patients experiencing clinical events, so that some prognostic analyses of individual cohort studies of human immunodeficiency virus-infected individuals had low statistical power. Because of this, the Antiretroviral Therapy Cohort Collaboration (ART-CC) of HIV cohort studies in Europe and North America was established in 2000, with the aim of studying the prognosis for clinical events in acquired immune deficiency syndrome (AIDS) and the mortality of adult patients treated for HIV-1 infection. In 2002, the ART-CC collected data on more than 12,000 patients in 13 cohorts who had begun combination ART between 1995 and 2001. Subsequent updates took place in 2004, 2006, 2008, and 2010. The ART-CC data base now includes data on more than 70 000 patients participating in 19 cohorts who began treatment before the end of 2009. Data are collected on patient demographics (e.g. sex, age, assumed transmission group, race/ethnicity, geographical origin), HIV biomarkers (e.g. CD4 cell count, plasma viral load of HIV-1), ART regimen, dates and types of AIDS events, and dates and causes of death. In recent years, additional data on co-infections such as hepatitis C; risk factors such as smoking, alcohol and drug use; non-HIV biomarkers such as haemoglobin and liver enzymes; and adherence to ART have been collected whenever available. The data remain the property of the contributing cohorts, whose representatives manage the ART-CC via the steering committee of the Collaboration. External collaboration is welcomed. Details of contacts are given on the ART-CC website (www.art-cohort-collaboration.org

Long-term Mortality in HIV-Positive Individuals Virally Suppressed for >3 Years With Incomplete CD4 Recovery

Virally suppressed HIV-positive individuals on combination antiretroviral therapy who do not achieve a CD4 count >200 cells/µL have substantially increased long-term mortality. The increased mortality was seen across different patient groups and for all causes of deat

Antiretrovirale Therapie der HIV-Infektion

Die antiretrovirale Therapie der HIV-Infektion hat sich in den letzten zwei Jahren aufgrund neuer Therapieoptionen und -strategien deutlich gewandelt. Die Empfehlungen zur antiretroviralen Therapie wurden daher in Abhängigkeit von klinischen, immunologischen und virologischen Parametern von einem deutsch-österreichischen Expertengremium überarbeitet. Eingebrachte Studienergebnisse betreffen insbesondere die Wertung der Kombinationstherapien von zwei nukleosidanalogen reverse Transkriptase-Inhibitoren (NRTI) in Kombination mit einem nichtnukleosidanalogen reverse Transkriptase-Inhibitor (NNRTI) oder einem Proteaseinhibitor und mit drei NRTI. Diese Kombinationen werden hinsichtlich ihrer therapeutischen Effektivität und ihres Nebenwirkungsprofils gewichtet. Für eine effektive Therapie sind eine Resistenztestung und eine Bestimmung von Plasmamedikamentenspiegeln bedeutsame Parameter, die für das Monitoring wichtig sind, sowie Faktoren, die einen Wechsel und eine Unterbrechung der Therapie indizieren, werden aufgezeigt.Antiretroviral Therapy in HIV-Infections During the last two years, antiretroviral therapy of HIV infections has changed dramatically. Therefore a board of German and Austrian physicians experienced in antiretroviral research and HIV patient care revised the guidelines for antiretroviral therapy and treatment and have strongly been influenced by data from latest studies on clinical, immunological and viral parameters. These studies mainly investigated combination therapies such as two nucleoside reverse transcritase inhibitor (NRTI) with one protease inhibitor or one non-nucleoside reverse transcriptase inhibitor with three NRTI. These combination therapies are evaluated in regard to their therapeutic effectiveness and their side effects. Resistance testing and drug monitoring are most important during therapy. Parameters which necessitate a change in or interruption of therapy are discussed
