Procalcitonin-Guided Therapy is a treatment approach that uses the levels of a substance called procalcitonin in your blood to help guide decisions about antibiotic use. Procalcitonin is a marker that can indicate the presence of a bacterial infection. In this trial, doctors use procalcitonin levels to decide when to start or stop antibiotics, aiming to reduce unnecessary antibiotic use and help treat severe infections more effectively.

Molecular-Guided Diagnosis is a method that uses advanced technology to identify the specific bacteria or viruses causing an infection. This approach helps doctors choose the most effective treatment by targeting the exact cause of the infection. In the trial, this method is used to ensure that patients receive the right antibiotics, reducing the use of broad-spectrum antibiotics and improving treatment outcomes for severe infections.

Severe infections – Severe infections are caused by pathogenic microorganisms such as bacteria, viruses, fungi, or parasites that invade the body and multiply, leading to significant illness. These infections can affect various parts of the body, including the lungs, bloodstream, or other organs, and can result in systemic inflammation. The progression of severe infections often involves an initial phase of localized symptoms, which can rapidly escalate to systemic involvement if not controlled. As the infection spreads, it can lead to symptoms such as high fever, chills, fatigue, and organ dysfunction. The body’s immune response to the infection can sometimes cause additional damage, leading to complications. The severity and progression depend on the type of pathogen, the site of infection, and the individual’s immune response.
