Pernio after COVID‐19 vaccination

Abstract: However, this limitation was reduced by using validated algorithms. 5,6 Secondly, reverse causation and possible confounders may limit the establishment of firm causal inferences even in well-designed observational studies. The strengths of our study are the large sample, the use of validated algorithms, and the proper matching of cases and controls.In conclusion, our study utilized a population-wide database and indicates that patients with SSDs do not appear to have a higher risk of developing psoriasis and… Show more

“…Pernio-like lesions and purpuric eruptions have been reported post-COVID-19 vaccination ( Figure 5 ). Of the 41 cases described in 11 observational studies [ 1 , 2 , 21 , 23 , 24 , 27 , 51 , 52 , 53 , 54 , 55 , 56 ], 25 (61.0%) were associated with BNT162b2, 9 (22.0%) with ADZ1222, and 7 (17.1%) with mRNA-1273 vaccination ( Table 1 ). In a series of 16 patients, purpuric manifestations appeared at a mean of 7.6 days after COVID-19 vaccination and lasted a mean of 15.7 days [ 2 ].…”

“…Vascular dysregulation that derives from both cytokine overactivation and environmental factors is supposedly responsible for ChLE [41]. Recently, rapid onset of chilblains has also been described in the course of mRNA vaccines [47]; this vaccine-derived phenomenon is currently believed to resemble a mimic of the natural immune response to SARS-CoV-2 that also shows similarity to ChLE [21,48]. When compared to mRNA vaccines and vector vaccines, inactivated viral vaccines represent poor inducers of cytotoxic CD8+ T cells [2].…”

“…
Since the emergence of mRNA COVID-19 vaccines, various secondary cutaneous reactions have been reported. 1,2 Commonly observed cutaneous reactions include local injection-site erythema or discomfort, as well as urticarial and morbilliform eruptions. [1][2][3] Less frequent sequalae include perniosis, herpes simplex virus reactivation, flares of psoriasis, and pityriasis rosea-like reactions.
