Concomitant medication(s) included: PREDNISONE. Past drug history included: Cyclosporine; Immunoglobulins, notes: IV. The following information was reported: SUBACUTE INFLAMMATORY DEMYELINATING POLYNEUROPATHY (medically significant), outcome "recovering", described as "acute inflammatory demyelinating polyneuropathy". The patient underwent the following laboratory tests and procedures: aspartate aminotransferase: 149 IU/l, notes: High; autoantibody test: negative; bacterial test: negative; biopsy liver: high-grade neuroendocrine tumor of unclear origin, notes: plus mild acute rejection in his graft; blood alkaline phosphatase: 233 IU/l, notes: High; blood bilirubin: 2.1 mg/dl, notes: High; blood chromogranin a: 403 ng/ml, notes: ULN less than 93 ng/mL; blood culture: negative; blood glucose: 87 mg/dl, notes: High; blood immunoglobulin a: 214 mg/dl; blood immunoglobulin g: 1194 mg/dl; blood immunoglobulin m: 71 mg/dl; blood thyroid stimulating hormone: 1.83 MiU/L; carcinoembryonic antigen: 36 ng/ml, notes: ULN lessthan3 ng/mL; c-reactive protein: 1 mg/dl; cryptococcus test: negative; culture: negative; culture urine: unknown; cytology: negative for carcinoma; cytomegalovirus test: negative; electrophoresis protein: ew tiny oligoclonal bands in gamma region; epstein-barr virus test: negative; flow cytometry: negative for atypical or malignant cells; fungal test: negative; negative; hiv test: negative; magnetic resonance imaging head: nornal; magnetic resonance imaging hepatobiliary: innumerable new bilobar lesions; magnetic resonance imaging spinal: normal; mycobacterium tuberculosis complex test: negative; neurological examination: bilateral lower extremity weakness, hyporeflexia, notes: and loss of pinprick sensation; physical examination: could only stand with support and required, notes: assistance for ambulation; platelet count: 89000 uL, notes: Low; polymerase chain reaction: negative; negative; protein total: 107 mg/dl, notes: High; red blood cell count: 2, notes: cells/cmm; red blood cell sedimentation rate: 20; sars-cov-2 test negative: negative, notes: by nasopharyngeal swab PCR; treponema test: nonreactive; vitamin b12: 884 pg/mL; white blood cell count: 1, notes: cell/cmm; white blood cell count: 3500 uL, notes: Low. Therapeutic measures were taken as a result of subacute inflammatory demyelinating polyneuropathy.; Sender's Comments: Based on the current available information and the plausible drug-event association, a possible contributory role of the suspect product BNT162B2 to the development of the Subacute inflammatory demyelinating polyneuropathy cannot be fully excluded.
