Clinical narrative: de novo Minimal change disease; This is a literature report for the following literature source(s):  A 74-year-old male patient received BNT162b2 (BNT162B2), as dose 2, single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "hypertension" (ongoing); "edema" (unspecified if ongoing), notes: 4-week history. Concomitant medication(s) included: AMLODIPINE; IRBESARTAN. Vaccination history included: Covid-19 vaccine (DOSE 1; MANUFACTURER UNKNOWN), for COVID-19 immunization. The following information was reported: GLOMERULONEPHRITIS MINIMAL LESION (hospitalization, medically significant), 2 days after the suspect product(s) administration, outcome "recovered", described as "de novo Minimal change disease". The patient underwent the following laboratory tests and procedures: Anti-glomerular basement membrane antibody: Negative; Antineutrophil cytoplasmic antibody: Negative; Antinuclear antibody: Negative; Biopsy: MCD EM normal but proteinuria, notes: already resolving by time of biopsy; Biopsy kidney: Unknown results, notes: On the 2nd day of hospitalization; Blood albumin: 2.0 g/dl; Blood creatinine: 0.81 mg/dl; Blood fibrinogen: Negative; Blood immunoglobulin A: Negative; Blood immunoglobulin G: Negative; Blood immunoglobulin M: Negative; Blood pressure measurement: 116/42 mmHg; Complement factor C1: Negative; Complement factor C3: Negative; Negative; Complement factor C4: Negative; Negative; Glomerular filtration rate: 71.0, notes: Units: mL/min/1.73m2; Hepatitis B virus test: Negative; Hepatitis C virus test: Negative; HIV test: Negative; Immunohistochemistry: Negative; kappa: Negative; Negative; 0.10; Microscopy: showed no extensive, notes: foot process effacement, deposits, or basement membrane abnormalities; There were no significant findings; showed no significant glomerular abnormalities,notes: and electron microscopy showed no extensive foot process effacement, deposits, or basement membrane abnormalities; Protein urine: resolving, notes: proteinuria; Urinary sediment: showed no red cells; Urine protein/creatinine ratio: 9.1, notes: units: g/g; 0.62, notes: decreased; Weight: 7 kg, notes: increase. Therapeutic measures were taken as a result of glomerulonephritis minimal lesion. Clinical Course: He had received 2nd dose of Pfizer/BioNTech vaccine 2 days before the onset date of edema. Units: 71.0 mL/min/1.73m2 (Modification of Diet in Renal Disease). Spontaneous remission from nephrotic syndrome was observed approximately 6 week after the onset of symptoms.; Sender's Comments: Based on available information, a contributory role of BNT162B2 to the event  glomerulonephritis minimal lesion cannot be fully excluded.
