ステロイド使用中の高齢者に生じたCOVID-19院内再燃症例

　During a pandemic like the novel coronavirus infection 2019 (COVID-19), the availability of inpatient beds is always a major issue. Thus, it is extremely important to release patients from isolation efficiently in order to maintain stable bed operations. However, in clinical practice, patients may develop fever again, before or after the timing specified by the Ministry of Health, Labor and Welfare (MHLW) for lifting isolation, and hence it may be difficult to determine whether the fever is due to a delay in recovery or due to relapse. The diagnosis of relapse is based primarily on the recurrence of symptoms consistent with COVID-19 and a positive PCR result, but few reports have focused on comparing the patterns of variation in two or more blood test findings over the course of the disease. In the present study, we study a case of relapse in an elderly patient on immunosuppressive drugs.
　Understanding the unique patterns of variability between baseline blood test values and acute infection test values in each individual patient may serve as an adjunctive tool to help diagnose COVID-19 relapse.
