Combined Use of a Respiratory Broad Panel Multiplex PCR and Procalcitonin to Reduce Antibiotics Exposure in Hospitalized Sickle-cell Adults With Acute Chest Syndrome.

Plain-language summary

Many patients with Sickle Cell Disease (SCD) may develop Acute Chest Syndrome (ACS). ACS is usually caused by a Lower respiratory tract infection (LRTI) which may be caused by either a bacterium or a virus. Antibiotics are usually used for 7 to 10 days with no microbiological workup. The hypothesis of the study is that the identification of the microorganisms might lead to a reduction of antibiotics exposure and a better care of the patients. We speculate that an early pathogen-directed strategy (respiratory broad panel multiplex PCR and early antibiotics interruption based on the PCT values decrease) might reduce the antibiotics exposure in SCD patients with ACS who are hospitalized and for whom an antibiotic treatment is indicated, as compared with usual care
