Clinical narrative: recurrent glomerulonephritis; acute tubulointerstitial nephritis; This is a literature report.  A 63-year-old male patient received BNT162b2 (BNT162B2), on 05Mar2021 as dose 1, single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "SLE", start date: 2000 (unspecified if ongoing), notes: without renal involvement; "Hypothyroidism" (unspecified if ongoing); "Valvular heart disease" (unspecified if ongoing); "Aortic valve replacement", start date: 2015, stop date: 2015. The patient's concomitant medications were not reported. Past drug history included: Hydroxychloroquine for SLE, notes: for greater than 5 years as his SLE was quiescent; Prednisone for SLE, notes: for greater than 5 years as his SLE was quiescent. The following information was reported: TUBULOINTERSTITIAL NEPHRITIS (hospitalization, medically significant) with onset 21Mar2021, outcome "unknown", described as "acute tubulointerstitial nephritis"; GLOMERULONEPHRITIS (hospitalization, medically significant) with onset 21Mar2021, outcome "unknown", described as "recurrent glomerulonephritis". The patient underwent the following laboratory tests and procedures: Antineutrophil cytoplasmic antibody: (unspecified date) Negative; Antinuclear antibody: (unspecified date) Negative; (unspecified date) Positive; (unspecified date) Positive; Biopsy kidney: (unspecified date) showed focal mild mesangial, notes: hypercellularity but no endocapillary hypercellularity, fibrinoid necrosis, crescent formation, or segmental sclerosis There were prominent protein droplets within cytoplasm of tubular epithelial cells. No significant IFTA was seen; (unspecified date) findings were consistent with lupus podocytopathy; (26Mar2021) Severe podocytopathy without significant immune-, notes: complex activity or glomerular hyper cellularity. There were prominent protein droplets within cytoplasm of tubular epithelial cells. No significant IFTA was seen; Blood albumin: (unspecified date) 3.6 g/dl; (unspecified date) 2.5 g/dl, notes: hypoalbuminemia; Blood creatinine: (unspecified date) 0.9-1.2 mg/dl, notes: Pre-vaccine; (unspecified date) 0.72 mg/dl; (unspecified date) 1.2 mg/dl; (unspecified date) 1.2 mg/dl; (unspecified date) 2.1 mg/dl, notes: Post-vaccine; Blood immunoglobulin A: (unspecified date) 1+; Blood immunoglobulin G: (unspecified date) 1+; Blood immunoglobulin M: (unspecified date) 1+; Blood potassium: (unspecified date) 2+; Complement factor: (unspecified date) Low; Double stranded DNA antibody: (unspecified date) Negative; Immune complex assay: (unspecified date) 1-2+; Immunology test: (unspecified date) showed weak segmental granular mesangial staining, notes: IgG (1+), IgA (1+), IgM (1+), C1q (1-2+). C3 (2+), k (2+), and ? (1+); anti-Smith antibodies: (unspecified date) Positive; (unspecified date) 2+; Light chain analysis: (unspecified date) 1+; Microscopy: (unspecified date) severe foot process, notes: effacement with mild microvillous transformation was observed Scattered mesangial but no subepithelial or subendothelial EDD were seen; Protein urine: (unspecified date) 100 mg/g; Protein urine: (unspecified date) 11.6 g, notes: 24-hour urine (Post-vaccine); Urine protein/creatinine ratio: (unspecified date) less than or equal to 0.5, notes: Unit: g/g (Pre-vaccine); (unspecified date) 0.1, notes: Unit: g/g. Therapeutic measures were taken as a result of glomerulonephritis, tubulointerstitial nephritis. Patient  received his second dose of the vaccine in May 2021. After 4 months of treatment, his UPCR was 0.1 g/g, serumalbumin 3.6 g/dL, and serum creatinine1.2 mg/dL. Prednisone was tapered down to5 mg/day, and MMF is being slowly tapered off as well.; Sender's Comments: Based on the currently available information the possibility of causal association between the events and the suspect drug BNT162B2  cannot be ruled out.
