Clinical narrative: patient presenting with autoimmune hepatitis less than two weeks after receiving his first dose of the Pfizer covid-19 vaccine; Scleral icterus; This is a literature report for the following literature source(s):   A 72-year-old male patient received BNT162b2 (BNT162B2), as dose 1, single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history included: "pulmonary sarcoidosis" (unspecified if ongoing), notes: well controlled; "scleral icterus" (unspecified if ongoing), notes: 2 weeks after receiving his first dose of COVID-19 Pfizer vaccination; "liver problems" (unspecified if ongoing); "fatigue" (unspecified if ongoing), notes: he appeared fatigued with icteric sclera; "stomach upset" (unspecified if ongoing); "nausea" (unspecified if ongoing); "constipation" (unspecified if ongoing); "anorexia" (unspecified if ongoing); "lost 11 pounds" (unspecified if ongoing), notes: over a 2 month period; "jaundice began" (unspecified if ongoing), notes: with no improvement in transaminase values. The patient's concomitant medications were not reported. Past drug history included: Vitamins d3, reaction(s): "jaundice"; B12, reaction(s): "jaundice", notes: with no improvement in transaminase values; Echinacea supplements, reaction(s): "jaundice", notes: with no improvement in transaminase values. The following information was reported: AUTOIMMUNE HEPATITIS (medically significant), outcome "recovering", described as "patient presenting with autoimmune hepatitis less than two weeks after receiving his first dose of the Pfizer covid-19 vaccine"; OCULAR ICTERUS (medically significant), 2 weeks after the suspect product(s) administration, outcome "recovering", described as "Scleral icterus". The patient underwent the following laboratory tests and procedures: Alanine aminotransferase: 1221, notes: Units: U/L; 1221, notes: Units: U/L; 118, notes: Units: IU/L; 1000s; with no improvement, notes: in transaminase values; Alpha-1 anti-trypsin: 208 mg/dl, notes: mildly elevated; Antimitochondrial antibody: were negative; Antinuclear antibody: direct was positive; Aspartate aminotransferase: 1177, notes: Units: U/L; 1234, notes: Units: U/L; 56, notes: Units: IU/mL; Biopsy: proven AIH just 13 days after receiving his first, notes: dose of the Pfizer COVID 19 vaccine; Biopsy liver: showed fulminant hepatitis with severe panlobular, notes: plasma cell-rich inflammation, extensive hepatocellular swelling, and frequent acidophil bodies; Blood alkaline phosphatase: 215 IU/l; Blood bilirubin: 7.2 mg/dl; 18.6 mg/dl, notes: (direct 14.8); Blood creatinine: 1.4 mg/dl; Blood immunoglobulin G: 3480, notes: was elevated; Blood iron: 256 ug/dL; Ceruloplasmin: was within normal range; Computerised tomogram abdomen: showed diminished attenuation of the liver, notes: suggesting steatosis; Gram stain: was consistentwith regenerative response; evidence of chronic injury and fibrosis but it was, notes: not clear whether this was true fibrosis or a result of his acute presentation; Haemoglobin: 13.8 g/dl; Hepatic enzyme: significant decrease in liver enzymes; complete normalization; Hepatitis A antibody: negative; Hepatitis B antibody: negative; Hepatitis B surface antigen: negative; Hepatitis C antibody: negative; International normalised ratio: 1.1; Abdominal examination: was grossly unremarkable; negative; Liver-kidney microsomal antibody: negative; Mean cell volume: 96, notes: Units: fL; physical examination: he appeared fatigued with icteric sclera; Platelet count: 267, notes: Units: K/cu mm; Serum ferritin: 3066 ng/ml; Smooth muscle antibody: weakly positive (1:22); Weight: lost 11 pounds over a 2-month period; White blood cell count: 6.9, notes: Units: K/cu mm; 22.4, notes: Units: K/cu mm. Therapeutic measures were taken as a result of ocular icterus.; Sender's Comments: Based on the information in the case report, a possible causal relationship between the events autoimmune hepatitis, ocular icterus and suspect drug BNT162B2 cannot be excluded.
