Abstract:

The current COVID-19 pandemic brings about a worldwide health crisis, especially in subjects with metabolic abnormalities. We devised New Short-term Intensive Insulin Therapy (N-SIIT) to avoid hypoglycemia and mitigate glucotoxicity and Insulin Resistance (IR). Here, we show a newly diagnosed diabetic subject with COVID-19 who was efficiently treated using N-SIIT. A 43-yearold male was hospitalized due to high fever, wet cough and loss of taste and smell. SARS-CoV-2 was positive in PCR test. Chest CT image showed pneumonia. Immediately, we started N-SIIT, but pneumonia drastically aggravated on day 3. However, by continuing N-SIIT, clinical data were improved, and various symptoms disappeared on day 8. The required insulin dose was decreased and finally replaced by oral diabetes agents. He was discharged on day 13 under stable conditions. Pulmonary infiltration in the chest CT completely disappeared. We did not use any antiviral medicine or steroids, but COVIT-19 was cured by N-SIIT. Indeed, N-SIIT mitigated hyperglycemic adverse effects, leading to reduction of inflammatory cytokines and decrease of angiotensin-converting enzyme 2 expressions which is known to act as a receptor for SARS-CoV-2. We also assume that the mitigation of glucotoxicity and IR might have revived his own healthy metabolism and immune response. It is necessary to perform further clinical trials with a large number of subjects to establish practical therapeutic strategies.
