New Onset Diabetes and Acute Pancreatitis- A Sequela of Long COVID?

ABSTRACT

Introduction: The association between worse COVID-19 outcomes and diabetes has been well-established in the literature. However, with more cases of new-onset diabetes and pancreatitis being reported with or after COVID-19 infection, it poses the question if there is a causal relationship between them. Case Description 31 y/o female with COVID-19 infection 4-6 weeks ago with moderate symptoms (not requiring hospital admission or monoclonal ab), presented to ED with bandlike epigastric pain radiating to back, which is worsened with food, associated with nausea, vomiting, polyuria, and fatigue. Workup showed lipase 232, AST 180, ALT 256. Blood glucose was 281 and HbA1c was 12. CT A/P showed post cholecystectomy status, normal pancreas with mesenteric adenitis. MRCP showed hepatic steatosis with trace fluid around the pancreas s/o inflammation, and no evidence of choledocholithiasis or biliary dilatation. She denied alcohol use and autoimmune workup for pancreatitis was unremarkable. Islet cell antibodies were negative. The patient improved with fluid resuscitation and was discharged home on insulin with plans to transition to oral agents outpatient. Discussion(s) Long COVID is defined as a range of conditions or symptoms in patients recovering from COVID-19, lasting beyond 4 weeks after infection. A retrospective cohort study showed increased new-onset diabetes incidence in patients after COVID-19. This was redemonstrated in a systematic review and meta-analysis that showed a 14.4% increased proportion of new diagnoses of diabetes in patients hospitalized with COVID-19. Possible pathophysiology that have been attributed to this include undiagnosed pre-existing diabetes, hyperglycemia secondary to acute illness and stress from increased inflammatory markers during the cytokine storm, the effect of viral infections on the pancreas, and concurrent steroid use in patients with severe respiratory disease. The binding of SARS-CoV-2 to ACE2 receptors is thought to the other mechanism by which COVID can cause pancreatitis and hyperglycemia. Study showed increased lipase and amylase levels in patients with COVID and the increase in serum levels was proportional to the severity of the disease. Patients who died due to COVID-19 were also found to have degeneration of the islet cells. While, several studies have showed new onset diabetes and pancreatitis during an active COVID infections, we need larger cohort studies to comment on its true association or causation, especially in patients with long COVID symptoms. As more cases of new onset diabetes and pancreatitis with COVID-19 are being reported, there may be a need for more frequent blood sugar monitoring during the recovery phase of COVID-19.Copyright © 2023
