2022 Aug (Bryan Daines et al) – A new eruption of bullous pemphigoid following mRNA COVID-19 vaccination

• Bullous pemphigoid (BP) is an uncommon autoimmune blistering disease which characteristically affects elderly adults with an incidence of 150–330 cases per million people per year in individuals over 80 years of age.
• The pathogenesis of BP involves autoantibodies directed against antigens in the hemidesmosome, causing a subepidermal split and subsequent bullae formation.
• Rare cases of BP have been reported following a variety of vaccinations including those for diphtheria, tetanus, pertussis, polio, influenza, Haemophilus influenzae type B, hepatitis B, bacillus Calmette-Guérin, pneumococcus, and herpes zoster, though true association is unclear
• 70M had 2nd dose of Pfizer mRNA
• next day he had an intensely pruritic eruption of pink plaques
• P/E: brightly erythematous, indurated plaques were present on the trunk, arms, and legs with intact and denuded bullae on the bilateral palms
• Diagnosis: bullous pemphigoid

2022 July (Norimatsu et al) – Pemphigus vulgaris with advanced hypopharyngeal and gastric cancer following SARS-CoV-2 vaccination

• 86M Japanese Man had 2nd Pfizer mRNA
• next day flaccid bullae appeared mainly in the lumbar region and presented to hospital 11 days later
• P/E: flaccid bullae scattered mainly in the right lumbar region and left upper arm.
• Diagnosis: Pemphigus Vulgaris

2022 Jun (Shanshal) – Dyshidrosiform Bullous Pemphigoid Triggered by COVID-19 Vaccination

• 90F had 1st Pfizer mRNA Vaccine on Dec.29, 2020
• she had a skin eruption 1 week later.
• after 2nd Pfizer mRNA dose on Mar.18, 2021, the rash worsened considerably with severe itching
• P/E: widespread eczematous rash and excoriation marks involving the trunk and extremities.
• On May 16, 2021 she was re-admitted with severe itchy and painful large intact blisters involving the palms and soles
• Diagnosis: bullous pemphigoid
• caused by acquired autoimmune IgG against two hemidesmosomal antigens (BpAg 180 and 230) in patients with underlying genetic predisposition.
• Dyshidrosiform pemphigoid is a rare clinical variant of bullous pemphigoid where itchy blisters primarily involve the palms and soles and may mimic a vesicular eczema flare-up

2022 Apr (Desai et al) – Bullous Pemphigoid Following the Moderna mRNA-1273 Vaccine

• 73F had 2nd dose of Moderna mRNA
• 24 hours later she developed intensely itchy skin eruptions that started on the trunk and later spread to extremities and the face
• P/E: tense, filled bullae were noted throughout her trunk, extremities and face, ranging in size from 5 mm to 2 cm

2022 Feb (Maronese et al) – Bullous Pemphigoid Associated With COVID-19 Vaccines: An Italian Multicentre Study

• Bullous pemphigoid (BP) is an autoimmune bullous disease caused by circulating autoantibodies toward the hemidesmosomal antigens BP180 and BP230.
• Cases of BP have been described following vaccinations against tetanus, poliomyelitis, diphtheria, influenza, pneumococcus, meningococcus, hepatitis B and rabies.
• mechanism by which COVID-19-vaccines may induce BP has not been clarified.
• Literature review: 21 cases found
  • 17 had Pfizer, 2 Moderna, 1 AstraZeneca, 1 had AstraZeneca & Pfizer
  • median age 82 years
  • median latency between Vaccine dose and cutaneous lesions = 27 days
  • 11/17 had positive anti-BP180 auto-antibodies
  • 5/17 had positive anti-BP230 auto-antibodies
