The patient's concomitant medications were not reported. Past drug history included: Mmf, stop date: May2019, for IgA nephropathy; High-dose steroids for IgA nephropathy. The following information was reported: GLOMERULONEPHRITIS (medically significant) with onset 18May2021, outcome "unknown", described as "recurrent glomerulonephritis"; TUBULOINTERSTITIAL NEPHRITIS (medically significant) with onset 18May2021, outcome "unknown"; FATIGUE (non-serious) with onset 2021, outcome "recovered"; PAIN (non-serious) with onset 2021, outcome "recovered", described as "injection-site pain". The patient underwent the following laboratory tests and procedures: Biopsy kidney: (unspecified date) showed focal segmental endocapillary, notes: hypercellularity, 20% of glomeruli with crescents including 3 cellular, 1 fibrocellular, and 1 fibrous. There was mesangial hypercellularity and 15% IFTA; (Nov2016) IgA nephropathy, notes: with cellular and fibrous crescents no significant IFTA; (17Aug2021) IgA nephropathy, notes: with cellular and fibrous crescents; Blood creatinine: (unspecified date) 0.9-1.0 mg/dl; (unspecified date) 1.13 mg/dl, notes: 8 weeks after the second dose; (Nov2020) 1 mg/dl; (unspecified date) 1.1 mg/dl; (unspecified date) 1.1 mg/dl; (unspecified date) 1.10 mg/dl, notes: Four weeks later, remained stable; Immunology test: (unspecified date) Dominantly diffuse mesangial, notes: and focal segmental capillary wall granular IgA staining (4+) was noted; Oxford classification Score: (unspecified date) M1, E1, S1, T0, and C1; Microscopy: (unspecified date) there were numerous, notes: mesangial/paramesangial EDD; Protein urine: (unspecified date) 1.3 g, notes: initially noted; Urine protein/creatinine ratio: (unspecified date) 1.1 g; (unspecified date) 2 g, notes: further increased to 2 g 2 months later; Urine protein/creatinine ratio: (Nov2020) 0.36, notes: Unit: g/g (Baseline proteinuria); Urine protein/creatinine ratio: (unspecified date) 2000 mg/g, notes: Peak proteinuria; (unspecified date) 1143 mg/g, notes: Nadir proteinuria; (unspecified date) 1143 mg/g, notes: Four weeks later. Therapeutic measures were taken as a result of glomerulonephritis, tubulointerstitial nephritis. ; Sender's Comments: Based on the information in the case report, a possible causal relationship between reported events and suspect drug BNT162B2 cannot be excluded  The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events.
