An auspicious triumph of recovery from dialysis-requiring acute kidney injury in COVID-19 in a patient with chronic kidney disease, α-1 antitrypsin deficiency, and liver transplant: A case report

We report a unique case of an immunosuppressed 67-year-old female with homozygous Z-allele mutation A1AT deficiency and liver transplant with baseline chronic kidney disease (CKD) stage IIIa with creatinine of 1 mg/dL and glomerular filtration rate (GFR) of 49 mL/min/1.73m² ~ 6 months before the presentation. She presented with COVID-19 mediated hypoxic respiratory failure complicated by AKI requiring provisional renal replacement therapy with recovery of kidney function with a new baseline of creatinine of 1.6 – 1.8 mg/dL with GFR of 31 mL/min/1.73m²
