Post-COVID-19 Vaccine Case Reports of Pityriasis Rosea and Pityriasis Rosea-like Eruptions
Various cutaneous reactions have been reported following COVID-19 vaccination globally. A registry-based study highlighted delayed large local reactions as the most common, with mRNA vaccines showing distinct reactions compared to viral vector vaccines. Three cases of pityriasis rosea (PR) and PR-like eruptions following COVID-19 vaccination were described in Oman Medical Journal. Two patients received Pfizer-BioNTech mRNA vaccines, while the third received the Oxford-AstraZeneca viral vector vaccine.
Case 1 involved a 19-year-old male presenting with PR-like eruption after the first dose of Pfizer-BioNTech vaccine. Case 2 was a woman experiencing PR after the first Pfizer-BioNTech dose, with a milder recurrence post-second dose. Case 3, a man in his seventies, developed PR-like eruption following the second dose of Oxford-AstraZeneca vaccine. Cutaneous reactions post-COVID-19 vaccination are diverse, including PR and PR-like eruptions. These reactions can occur with both mRNA and viral vector vaccines. Mechanisms may involve immune dysregulation and viral reactivation. Diagnosis and management rely on clinical presentation and histopathological examination. PR and PR-like eruptions post-COVID-19 vaccination are rare but possible. Vigilance in monitoring skin reactions following vaccination is crucial. Further studies are needed to understand the relationship between vaccination and cutaneous reactions, especially regarding viral reactivation.
Risk of Delayed Adverse Events in COVID-19 Vaccination for Patients With Autoimmune Diseases
Despite documented safety profiles of COVID-19 vaccines, vaccine hesitancy persists among individuals with immune-mediated inflammatory diseases (IMIDs), especially due to limited data on long-term safety. This study aimed to assess delayed adverse events (DAEs) occurring over seven days post-vaccination in systemic lupus erythematosus (SLE) and other rheumatic and non-rheumatic autoimmune diseases (rAIDs and nrAIDs) compared to healthy controls (HCs). Data were collected via the COVAD-2 online survey from over 150 centers in 106 countries between February and June 2022. Logistic regression analysis, adjusting for confounders, compared adverse events among groups.
Among 7203 participants, SLE patients reported higher rates of major DAEs and hospitalizations compared to HCs. They also experienced more severe rashes compared to individuals with rAIDs and higher hospitalization rates compared to those with nrAIDs. Differences in adverse events were observed between vaccine types, with Moderna recipients experiencing more hospitalizations. SLE patients without autoimmune multimorbidity reported fewer minor DAEs compared to those with comorbid nrAIDs. SLE patients had a higher risk of hospitalization post-vaccination compared to HCs. Close monitoring of SLE patients post-vaccination can aid in early detection of adverse events, informing patients, especially those with multiple autoimmune conditions, and providing necessary support.
New-Onset Pemphigus Following COVID-19 in 73-Year-Old Patient
The study presents a case of a 73-year-old woman developing pemphigus 2 weeks after contracting COVID-19, shedding light on the limited data regarding pemphigus incidence post-COVID-19 infection. The patient presented with blistering eruptions on multiple body parts post-COVID-19 diagnosis, prompting further investigation. Biopsies indicated features of pemphigus vulgaris (PV) and paraneoplastic pemphigus (PNP), with subsequent negative malignancy findings. Treatment with prednisone and mycophenolate mofetil led to complete remission at 9 months follow-up. COVID-19 has been linked to autoimmune diseases, possibly through molecular mimicry and immune dysregulation mechanisms. Reports suggest a time lag between COVID-19 and pemphigus onset, possibly due to aberrant immune responses triggered by the virus. Interestingly, the patient exhibited features of both PV and PNP, suggesting a complex autoimmune response influenced by COVID-19. This case underscores the need for vigilance regarding autoimmune manifestations post-COVID-19.
Mask-Induced Koebner Phenomenon in Patients With Pemphigus
During the COVID-19 pandemic, the widespread use of face masks has led to an increase in dermatoses, including reports of Koebner phenomenon, especially in patients with psoriasis. However, there has been limited documentation of mask-induced pemphigus lesions. This study presented 2 cases of patients with pemphigus developing new or persistent lesions on their noses, the area most irritated by mask usage. The first case involved a 56-year-old man with pemphigus vegetans, who developed nasal lesions four months after the pandemic began, coinciding with increased mask usage. Treatment with oral methylprednisolone and azathioprine resulted in mild improvement. The second case was a 47-year-old man with pemphigus vulgaris, exhibiting erosive lesions on the nose and oral mucosa, exacerbated by prolonged mask wearing. Despite treatment, nasal lesions persisted, indicating a possible mask-induced Koebner phenomenon. While previous reports linked pemphigus lesions to trauma or light exposure, the consistent occurrence of nasal lesions in these cases highlights the role of mask-related minor traumas.
Impact of Koebner Phenomenon in Pemphigus Patients Amidst Pandemic Mask Usage
While the Koebner phenomenon is rare, its potential occurrence in pemphigus patients has become a topic of increasing concern, particularly in the current global pandemic scenario marked by widespread mask usage. The Koebner phenomenon, characterized by the development of skin lesions in areas of trauma or injury, poses a unique challenge for individuals with pemphigus, a chronic autoimmune skin disease.
Possible Risk Factors
The Koebner phenomenon in pemphigus patients can be triggered by various factors, including mechanical trauma, infections, and inflammatory conditions. With the ongoing COVID-19 pandemic prompting the widespread adoption of face masks as a preventive measure, the risk of mask-induced trauma leading to the Koebner phenomenon has gained attention among dermatologists and healthcare providers.
Understanding Pemphigus
Pemphigus is a group of rare autoimmune diseases that cause blistering of the skin and mucous membranes. The condition is characterized by the production of autoantibodies that target proteins involved in cell adhesion, leading to the formation of blisters and erosions on the skin. The Koebner phenomenon poses a significant concern for pemphigus patients, as any form of trauma or pressure on the skin can trigger the development of new lesions.
Preventive Measures
Given the potential risk of the Koebner phenomenon in pemphigus patients, especially in the context of widespread mask usage during the COVID-19 pandemic, it is essential for individuals with pemphigus to take preventive measures to minimize the risk of skin trauma. This may include using soft, breathable masks, avoiding tight-fitting or abrasive materials, and practicing proper skincare routines to protect the skin.
Conclusion
In conclusion, while the Koebner phenomenon is rare, its potential occurrence in pemphigus patients necessitates careful consideration, particularly in the current scenario of widespread mask usage during the COVID-19 pandemic. By raising awareness about the risk factors and preventive measures, healthcare providers can help pemphigus patients manage their condition effectively and minimize the risk of skin trauma-induced exacerbations.
