A case of COVID-19 pneumonia successfully treated with favipiravir (Avigan) in which serum SARS-CoV-2 RNA detected by LAMP method was clinically useful.

A 49-year-old Japanese male was managed by mechanical ventilation due to coronavirus disease 2019 (COVID-19) pneumonia. Favipiravir as an antiviral therapy, and anti-inflammatory treatment were administered. SARS-CoV-2 RNA was detected in serum by the loop-mediated isothermal amplification (LAMP) method on Day 9; favipiravir treatment was continued.

[Investigation of the procalcitonin and microbiology test and antibiotics situation from our hospital].

Procalcitonin (PCT) was first described as a sepsis-associated protein in 1993. PCT is increased in the blood at the time of infection by bacteria. Therefore, it is used as an auxiliary indicator of sepsis diagnosis.
