Active clinical trials for "Infections"

The purpose of this study is to find out if we can predict the progress of acute upper respiratory tract infection to acute bacterial rhinosinusitis in Finnish conscripts by symptoms, clinical, endoscopic or radiological findings, middle meatal swab samples or nitric oxide measurement.

The purpose of this investigation is to evaluate how early biomarkers of infection and inflammation perform in identifying patients at risk for poor outcome in sepsis and septic shock.

The RATIO registry is a French registry designed by a multidisciplinary group to collect data on opportunistic and severe bacterial infections and lymphoma in patients treated with TNF-a antagonists ( infliximab, etanercept and adalimumab). A total of 486 medical units in metropolitan France participate in the RATIO registry. All diagnosis are retained after validation by 2 qualified infectious disease or haematologist physicians (on the basis of the standardized case report form, the hospitalisation summary, and the microbiological and radiological results). Risk factors for developing these conditions when treated by TNF-a antagonists will be identified in a case control study. Incidence of these diseases will be calculated.

The immune systems of some individuals may be capable of resisting HIV infection. These individuals do not appear to be infected with HIV despite multiple sexual encounters with HIV infected partners. This study will examine the immune systems of these individuals to determine what factors are responsible for their ability to resist HIV infection. Study hypothesis: Some long-term, multiply-exposed seronegative persons have relative resistance to HIV infection maintained by T cell responses.
