COVID vaccine-induced pustular psoriasis in patients with previous plaque type psoriasis

Bibliometric analysis and description of research trends in the treatment of psoriasis with biologic agents in the past two decades (2004-2023)

BACKGROUND

Biologics are essential in treating psoriasis. In recent years, the pathogenesis exploration and development of new target drugs have provided a more complete evidence-based foundation for the biological treatment of psoriasis. This study aims to use bibliometrics to analyze the research status and development trends of biologics in psoriasis.

METHODS

The bibliometric analysis of publications related to biologics in psoriasis from 2004 to 2023 was conducted using the Web of Science Core Collection (WoSCC) database as the search data source. To perform the bibliometric analysis and create visual knowledge graphs, CiteSpace, the Bibliometrix R package, and VOSviewers were utilized.

RESULTS

The study included a total of 3800 articles. The United States had the highest number of publications. The leading authors and institutions were Steven R. Feldman and the University of Manchester, respectively, in the global partnership. The cluster plot divided all keywords into 11 categories. Currently, Secukinumab and Guselkumab are representative biological agents being studied due to their considerable efficacy and long-term safety.

CONCLUSIONS

Targeted therapy has emerged as a significant trend in the current treatment of psoriasis. Early and active use of biologics can effectively control disease progression, prevent or delay the occurrence of comorbidities, and may even alter the natural course of psoriasis. However, further investigation is required to fully understand the specific mechanisms of psoriasis and the use of biological agents.

Plaque Psoriasis Exacerbation and COVID-19 Vaccination: Assessing the Characteristics of the Flare and the Exposome Parameters

The diverse patient population and widespread vaccination in the COVD-19 era make vaccine-triggered episodes of psoriasis an ideal model of exposome research. This scenario explores the fine balance between protective and exacerbating factors, providing insights into the complex relationship between environmental exposure and psoriasis immunopathogenesis when a trigger appears, such as that of the hyperinflammatory state induced by the COVID-19 vaccine. Analyzing interactions between vaccine-induced phenomena and exposome parameters may provide clinically relevant information important for personalized medicine decision-making. We performed a literature review seeking patients with plaque psoriasis flares or new onset or change in plaque psoriasis into another psoriasis subtype, such as pustular or erythrodermic flare, focusing on the inner and external exposome traits of patients. We identified 71 patients with plaque psoriasis flares, 12 patients with new-onset psoriasis, and 17 with plaque psoriasis subtype change, and assessed the COVID-19 vaccine-induced plaque psoriasis in terms of clinical presentation, post-vaccination flare period and treatment status, as well as inner exposome parameters (genomics, oxidative stress, hormonal impact due to gender, aging, skin color) and external parameters (UV, infectomics). Novel data on psoriasis flares following COVID-19 vaccination are primarily obtained by combining exposome and vaccine-triggered episode features and characteristics and comparing them with similar psoriasis flares unrelated to COVID-19 vaccination.

New-Onset and Exacerbation of Psoriasis following COVID-19 Vaccination: A Systematic Review of Case Reports and Case Series

Introduction

Although uncommon, several cases of new-onset and exacerbation of psoriasis have been reported after coronavirus disease 2019 (COVID-19) vaccination. This study aims to systematically review reports regarding new-onset and exacerbation of psoriasis to identify features related to that condition following COVID-19 vaccination.

Materials and Methods

Three databases were utilised, namely, PubMed, Google Scholar, and EBSCOHost to search for literature published until June 2022. We used the following MeSH terms: "psoriasis," "exacerbation," "induced psoriasis," and "COVID-19 vaccination." The included literature must report the case/(s) of psoriasis exacerbation in previously-in-remission or induced psoriasis in individuals receiving any dose of COVID-19 vaccines regardless of the type.

Results

Among 33 selected studies, an overall mean age was 57.52 ± 15.92 years. Female (n = 40; 54.8%) was more frequently reported than male (n = 33; 45.2%). In terms of vaccine types, Pfizer is the most commonly reported (49 cases; 67.1%), followed by Astra-Zeneca (13 cases; 17.8%), Moderna (10 cases; 13.7%), and CoronaVac (1 case; 1.4%). The onset of psoriasis after receiving the COVID-19 Vaccines was varied, ranging from 1 to 90 days (Mean ± SD: 15.75 ± 18.22). Plaque psoriasis was most commonly reported, followed by pustular, guttate and other types of psoriasis. Reported cases were frequently treated with topical steroids and monoclonal antibodies monotherapy.

Conclusions

Although the cases of new-onset and exacerbation of psoriasis after COVID-19 vaccination is quite scarce, the possibility of occurrence should be acknowledged and managed properly; and patients should be informed, particularly ones with history of psoriasis without discouraging patients to take vaccine.

New Onset and Exacerbation of Psoriasis Following COVID-19 Vaccination: A Review of the Current Knowledge

COVID-19 vaccination was the main measure to overcome the pandemic. As with other drugs and vaccines, mild to moderate adverse events have been reported following vaccination. In addition, several cutaneous reactions have been described. In particular, there are several reports investigating de novo psoriasis or the exacerbation of psoriasis following COVID-19 vaccination. However, data on the possible pathogenetic mechanisms as well as comprehensive manuscripts on the topic are scant. Thus, the aim of our manuscript was to perform a review of the current literature on post-COVID-19 vaccination exacerbations and new-onset psoriasis in order to offer a wide perspective on this area and to point out possible pathogenetic mechanisms. Research on the current literature was performed following PRISMA guidelines. In total, 49 studies involving 134 patients developing new-onset psoriasis (n = 27, 20.1%) or psoriasis exacerbation (n = 107, 79.9%) were collected. Although cases of de novo psoriasis or a worsening of psoriasis have been reported following vaccination, all of the cases have been successfully treated while overall benefit-risk profile of COVID-19 vaccination does not justify vaccine hesitancy due to the risk of psoriasis being developed or worsening. Certainly, further studies are needed to identify possible pathogenetic mechanisms in order to identify "at-risk" patients. Finally, vaccination should not be discouraged.

Pustular Eruption following COVID-19 Vaccination: A Narrative Case-Based Review

From the beginning of public vaccinations until the relaxation of COVID-19 measures, many case reports, case series and case-control studies have been published indicating cutaneous side effects of COVID-19 vaccination. Post-vaccination pustular eruption was reported as well, with a challenging differential diagnosis between pustular psoriasis, AGEP (acute generalized exanthematous pustulosis) and neutrophil pustular eruptions. We report a case of 56-year-old woman presented with acute generalized pustular flare up culminated 5 days after the second dose of BNT162b2(Pfizer) vaccination. She was diagnosed with pustular psoriasis flare and due to the regulating role of IL-1 in pustular psoriasis and in the cytokine storm observed in cases of COVID-19 postvaccination inflammation; we decided to treat the patient with an IL-1 antagonist, subcutaneous anakinra (100 mg daily) along with acitretin. One week later, after anakinra withdrawal, she presented a pustular psoriasis flare and a 7-day anakinra re-administration led to a satisfactory improvement in the skin lesions. We also reviewed the medical literature and found 28 case reports with pustular eruption after the COVID-19 vaccination. We compared the patients reported, regarding sex, age, number of doses, post-vaccination period and vaccine brand, and compared those results with our patient. Finally, as indicated by our case and other cases with similarly treated pustular eruptions. targeted therapy to this cytokine imbalance such as anakinra (IL-1) antagonist can improve the clinical course of the patient.

The Impact of COVID-19 Vaccination on Inflammatory Skin Disorders and Other Cutaneous Diseases: A Review of the Published Literature

Background: Four vaccines have been authorized by the European Medicines Agency (EMA): viral vector-based vaccines (AstraZeneca; AZD1222 and Johnson & Johnson; Ad26.COV2. and 2 mRNA-based vaccines (Pfizer/BioNTech; BNT162b2 and Moderna; mRNA-1273). Adverse events (AEs) related to vaccination have been described in the literature. The main aim of the dermatological practice was to avoid the diffusion of COVID-19, allowing the continuity of care for patients. Objective: The aim of this review article is to investigate current literature regarding cutaneous reactions following COVID-19 vaccination, mainly inflammatory dermatological diseases. Materials and methods: Investigated manuscripts included metanalyses, reviews, letters to the editor, real-life studies, case series, and reports. Results: We selected a total of 234 articles involving more than 550 patients. We have divided the results section into various sub-sections to ensure greater understanding for readers. Conclusions: Clinicians should keep in mind the possibility of new onsets or the worsening of several dermatoses following vaccination in order to promptly recognize and treat these AEs. Certainly, vaccination should not be discouraged.

The Relationship Between Psoriasis, COVID-19 Infection and Vaccination During Treatment of Patients

Since the outbreak of the COVID-19 pandemic in December 2019, scientists worldwide have been looking for a way to control this global threat. One of the most successful and practical solutions has been the development and worldwide distribution of the COVID-19 vaccines. However, in a small percentage of cases, vaccination can lead to de novo development or exacerbation of immune or inflammatory conditions such as psoriasis. Due to the immunomodulatory nature of this disease, people affected by psoriasis and other related skin conditions have been encouraged to receive COVID-19 vaccines, which are immunomodulatory by nature. As such, dermatological reactions are possible in these patients, and cases of onset, exacerbation or change in the type of psoriasis have been observed in patients administered with COVID-19 vaccines. Considering the rarity and minor nature of some of these cutaneous reactions to COVID-19 vaccination, there is a general consensus that the benefits of vaccination outweigh the potential risks of experiencing such side effects. Nevertheless, healthcare workers who administer vaccines should be made aware of the potential risks and advise recipients accordingly. Furthermore, we suggest careful monitoring for potentially deleterious autoimmune and hyperinflammatory responses using point-of-care biomarker monitoring.

Safety and Efficacy of Covid-19 Vaccination in Patients Undergoing Biological Treatments for Psoriasis

The introduction of biologic drugs revolutionized the treatment of psoriasis, shifting treatment goals to higher treatment outcomes and less frequent safety issues. The outbreak of Coronavirus disease 2019 (COVID-19) represented a worldwide challenge, strongly affecting lifestyle, global economy, and overall health. Among the strategies adopted to contain the spreading of the infection, vaccination is the main one. In this context, the introduction of COVID-19 vaccines raised several doubts about their effectiveness and safety in patients undergoing therapy with biological for psoriasis. Even if molecular and cellular mechanisms by which COVID-19 vaccines lead to psoriasis development have not yet been fully elucidated, vaccination itself can trigger the release of interleukin (IL)-6, interferon (IFN) and tumor necrosis factor (TNF) α by T-helper (Th)1/Th17 cells. All these cytokines are involved in psoriasis pathogenesis. Thus, the aim of this manuscript is to review current literature on the safety and effectiveness of COVID-19 vaccination in psoriasis patients undergoing treatment with biologics, in order to clarify any concerns.

Cutaneous Reactions Following COVID-19 Vaccination: A Review of the Current Literature

The outbreak of coronavirus disease 2019 (COVID-19) represented a new worldwide challenge, strongly impacting on the global economy, overall health and lifestyle. Since then, several strategies have been adopted to contain the widespread of infection. Among these, vaccination is currently the most important measure to fight against the pandemic. However, several concerns such as slower-than-hoped-for rollout, the hurried approval with limited data, the mechanism of action (in particular mRNA-based), and the uncertain duration of protection they afforded were initially raised. Moreover, even if cutaneous reactions have been rarely reported in clinical trials, global mass vaccination showed several dermatologic reactions not initially recognized, leaving dermatologists to decide how to diagnose and treat them. In this scenario, dermatologists should be ready to promptly recognize these clinical manifestations. Thus, the aim of this manuscript is to review current literature on cutaneous reactions following COVID-19 vaccination, particularly inflammatory dermatological diseases, in order to help clinicians to better understand these dermatological conditions and to provide an extensive overview of all the vaccine-related skin manifestations.

New Onset and Exacerbations of Psoriasis Following COVID-19 Vaccines: A Systematic Review

BACKGROUND

Vaccination has been promoted to control viral transmission in response to the coronavirus disease 2019 (COVID-19) pandemic. Cases of new-onset or exacerbation of psoriasis, an immune-mediated inflammatory disease, were reported following COVID-19 vaccination. However, a comprehensive review examining the association between COVID-19 vaccination and the occurrence or exacerbation of psoriasis has yet to be performed.

OBJECTIVE

The aim of this systematic review is to investigate the demographics, clinical variables, and outcomes associated with psoriasis following COVID-19 vaccination.

METHODS

A systematic literature search was conducted using the PubMed, Embase, Web of Science, and Cochrane databases from database inception to April 25, 2022. The review included studies with relevant terms, including 'psoriasis,' 'psoriasis vulgaris,' 'guttate psoriasis,' 'pustular psoriasis,' 'palmoplantar pustulosis,' 'psoriatic erythroderma,' 'psoriatic arthritis,' 'COVID-19,' and 'vaccine.' We included all studies reporting at least one patient who developed new-onset psoriasis or experienced a psoriasis flare following at least one dose of any COVID-19 vaccine. A flare was defined as the worsening of disease conditions after vaccination according to the study by Gregoire et al. The appraisal tool described by Murad et al. was used to assess the quality of case reports and series, whereas the National Institute of Health quality assessment tool was used to assess observational studies.

RESULTS

The initial search yielded 367 results, including 7 studies reporting new-onset psoriasis, 32 studies reporting psoriasis flares, and 4 studies reporting both. The most commonly observed psoriasis subtype was plaque-type psoriasis. mRNA vaccines, including those produced by Moderna and BioNTech/Pfizer, were frequently associated with subsequent psoriasis episodes. First, second, and third vaccine doses were associated with psoriasis incidents, with the second dose most frequently associated with psoriasis flares. Delayed onset was observed, ranging from 2 to 21 days in the new-onset group and from 1 to 90 days in the flare group. Most patients experienced favorable outcomes, with improvement or resolution occurring within 3 days to 4 months.

CONCLUSIONS

Both new-onset psoriasis and psoriasis flares were reported as cutaneous adverse events following COVID-19 vaccination. Psoriatic patients may require regular follow-up before and after COVID-19 vaccination.

Curbing COVID-19 Vaccine Hesitancy from a Dermatological Standpoint: Analysis of Cutaneous Reactions in the Vaccine Adverse Event Reporting System (VAERS) Database

OBJECTIVES

Adverse reactions to the COVID-19 vaccines have been of interest since their emergency authorization. Cutaneous manifestations of the vaccines are not well studied. We aimed to characterize cutaneous reactions to the Moderna (mRNA-1273) and the Pfizer-BioNTech (BNT162b2) COVID-19 vaccines on a large, national scale.

METHODS

The Vaccine Adverse Event Reporting System was filtered for cutaneous and hair and nail reactions to the COVID-19 vaccines. Patient demographics and past medical histories, vaccine manufacturer and dosing, symptom timing, reaction location, and patient outcomes were extracted from each report.

RESULTS

As of December 24, 2021, there were 67,273 cutaneous reactions to all COVID-19 vaccines, with most patients receiving the Moderna (mRNA-1273) or Pfizer-BioNTech (BNT162b2) vaccines. The most common reactions overall were injection-site reaction, urticaria, and papular rash, with injection-site reaction more common after the Moderna (mRNA-1273) vaccine, and all other cutaneous reactions more common after the Pfizer-BioNTech (BNT162b2) vaccine. Patients with past histories of psoriasis, urticaria, and local site reactions to a vaccine were more likely to report these same symptoms after the COVID-19 vaccine.

CONCLUSION

Patients should be counseled about these potential dermatologic reactions to the COVID-19 vaccines. Most occur within the first few days after vaccination, and are mild and self-limiting. Patients should therefore be encouraged that it is safe to receive the COVID-19 vaccine from a dermatological perspective.
