Abstract Background : To date, there has been no silver bullet against Coronavirus disease 2019 (COVID-19). After starting an initial treatment, we sometimes experience an exacerbation of pneumonia due to COVI...D-19.
Patients and Methods: To begin with, we retrospectively summarized our series of COVID-19 cases hospitalized during a third wave of COVID-19 in Japan (November, 2020 - March, 2021). Then we extracted exacerbated cases for further analysis and focused on changes in the laboratory data and its management
Results : Thirty patients participated in this study. The mean age ± standard deviation was 70.9 ± 15.0. Twenty patients needed oxygen supply at the time of admission. Most of the administered medication was corticosteroid (24 cases). However, during the corticosteroid treatment, five patients experienced the exacerbation of pneumonia due to COVID-19. Among laboratory tests, the elevation of lactate dehydrogenase was detected at an exacerbation (four cases). With the exception of one patient transferred to another hospital, we raised the dose of corticosteroids for three cases. Although one patient died, the others finally improved.
Conclusion : Lactate dehydrogenase might be a sensitive marker for cases of an exacerbation of pneumonia due to COVID-19, and the intensification of treatments such as high-doses of corticosteroids could be helpful in some cases.
