Retrospective Non-interventional Analysis of Opportunistic Infections in Immunocompromised and Frail Patients

Study Overview
=================
Brief Summary
-----------------
The analysis of a cohort of consecutive non-selected patients from the Strasbourg University Hospital, and therefore representative of the real life, will allow better identifying the risk factors for these infections (by comparison with a cohort of patient with similar conditions of immunosuppression and no infection) and improving the diagnosis and therapeutic management. The primary objective is to identify prognosis factors affecting survival in patients with opportunistic infections

| --- | --- | --- |
| Short- and long-term survival, overall and in specific subgroups of patients |  | Long-term time point : 1st may 2019 | 
| Short- and long-term survival, overall and in specific subgroups of patients |  | Short term : 1 month | 
| Short- and long-term survival, overall and in specific subgroups of patients |  | Short term : 3 months |

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Risk factors predisposing to opportunistic infections - age - gender - Type of work - Location - Tobacco use |  | first day of opportunistic infection | 
| Prognosis factors in patients with opportunistic infection affecting the response to antimicrobial therapy (using response criteria defined by EORTC/MSG) |  | first day of opportunistic infection | 
| Identification of baseline prognosis factors affecting the 3 months survival |  | first day of opportunistic infection | 
| Identification of baseline prognosis factors affecting the 6 months survival |  | first day of opportunistic infection | 
| Incidence of specific opportunistic infections in different host groups |  | evolution of a 20-year-period | 
| Description of imaging patterns opportunistic infections: analysis of chest CT-scan and cerebral CT-scan and MRI by radiologists |  | at first day of infection and up to 12 weeks | 
| Assessment of performance of Aspergillus galactomannan detection test in serum |  | at onset and up to 1 week | 
| Assessment of performance of Aspergillus galactomannan detection test in bronchoalveolar lavage |  | at onset and up to 1 week | 
| Response rate |  | at 1, 3 and 6 months |
