Tacrolimus-induced acute pancreatitis and diabetic ketoacidosis (DKA) in pediatric kidney transplant recipient.

BACKGROUND: Calcineurin inhibitors (CNIs) are often associated with abnormalities in glucose and lipid metabolism. Tacrolimus is the most potent CNI which is nowadays used almost universally as a part of triple-drug immunosuppression after kidney transplantation. Tacrolimus can cause islet cell damage and decrease in insulin secretion which can lead to post-transplant diabetes mellitus and rarely diabetic ketoacidosis. Although rare, acute pancreatitis has also been implicated by a few case reports to be associated with tacrolimus. However, tacrolimus-induced acute pancreatitis has not been reported in pediatric kidney transplant recipient till date. CASE DESCRIPTION: We report the first case of tacrolimus-induced acute pancreatitis in association with hypertriglyceridemia and DKA in a child early after kidney transplant. The patient was managed with supportive treatment, and tacrolimus was stopped for three days and then switched to cyclosporine-based regimen. The patient became euglycemic within 8 weeks of switching to cyclosporine and did not have any recurrence of pancreatitis. CONCLUSION: Tacrolimus-induced pancreatitis is rare in the setting of kidney transplants and prompt diagnosis and management can lead to a successful outcome.

Post-COVID Multisystem Inflammatory Syndrome-Adult (MIS-A) Presenting with Rhabdomyolysis and AKI.

Multisystem inflammatory syndrome is a rarely reported post-COVID (coronavirus disease) phenomenon in adults. Our understanding of the multisystem inflammatory syndrome- adult (MIS-A) is based on multiple case reports that have demonstrated heterogeneous clinical presentations and treatment options. Rhabdomyolysis is an unusual presentation of MIS-A. We report the case of a 61-year-old man who presented with rhabdomyolysis with acute kidney injury (AKI), acute inflammatory demyelinating polyneuropathy (AIDP), myocarditis, disseminated intravascular coagulation, and minimal respiratory symptoms. The patient was found to have post-COVID inflammatory syndrome and recovered with supportive treatment and intravenous immunoglobulin (2 g/kg over 5 days). COVID-19 (coronavirus disease 2019) antibody positivity played a significant role in making the diagnosis of MIS-A and in providing prompt treatment.
