Management of Clostridioides difficile infection: Diagnosis, Treatment, and Future Perspectives.
Clostridioides difficile infection is the most common healthcare-associated infection in the United States, with potential life-threatening complications and a significant impact on the costs of care. Antibiotic stewardship as well as discontinuation of chronic acid suppressive therapy are key for its prevention and treatment. Effective infection management requires appropriate interpretation of diagnostic tests, as well as the use of vancomycin and fidaxomicin as first-line treatment. Novel treatments such as Bezlotoxumab, fecal microbiota transplant, and live biotherapeutic products are proven effective in recurrent C. difficile infection and address dysbiosis.

Fever of unknown origin and inflammation of unknown origin are highly challenging diagnostic conditions. The current practice for evaluating patients is to conduct a positron emission tomography-computed tomography (PET-CT) scan as either a first- or a second-line modality. We aimed to assess the contributory effect of PET-CT to the diagnosis and compare it with the contributory effect of CT alone. ⋯ PET-CT has a contributory effect of 75% for the diagnosis of fever of unknown origin and inflammation of unknown origin. PET-CT had superior sensitivity and inferior specificity vs the CT scan.
