ABSTRACT
BACKGROUND SARS-CoV-2 infection or COVID-19 disease has been linked to the onset of diabetes and metabolic dysregulation because it has been suggested that viral entry proteins, specifically ACE2 and TMPRSS2, are expressed in the exocrine cells and ductal epithelium of the pancreas. Because of the unknown effect this can have on islet function, there can be doubt that patients with previous SARS-CoV-2 infections are good candidates for autologous islet transplantation after total pancreatectomy (TPAIT). CASE REPORT A patient with a history of chronic pancreatitis and previous non-surgical interventions was presented as a viable candidate for TPAIT at our institution. Approximately 1 month later, the patient contracted a SARS-CoV-2 infection, resulting in a mild case of COVID-19. The infection resolved without the need for hospitalization. At the time of this occurrence, COVID-19 was primarily considered a respiratory ailment, and little was known of the potential association between metabolic dysfunction and SARS-CoV-2. Islet isolation and surgery proceeded in a textbook manner with no surgical complications. The patient was weaned off exogenous insulin within 3 months after transplantation. CONCLUSIONS Favorable outcomes after surgery included pain reduction, islet function, and improved quality of life for the patient in the first 6 months after the procedure. These successful results demonstrate that SARS-CoV-2 infection did not prevent the patient from achieving good glucose regulation after auto-islet transplantation. This outcome suggests that, at least in this instance of mild infection, there were no long-lasting negative COVID-19-associated effects on the transplanted islets that might impact islet function.
