Cutaneous reactions reported after Moderna and Pfizer COVID-19 vaccination: A registry-based study of 414 cases

Experience and side effects of COVID-19 vaccine uptake among university students: a cross-sectional survey study

Introduction

Many people expressed concern over coronavirus vaccinations' reliability and side effects. This research aimed to assess university students' perceptions and experiences regarding the side effects of the COVID-19 vaccines in Bangladesh.

Method

We conducted an online cross-sectional survey to collect responses from university students vaccinated with any vaccines administered in Bangladesh between November 2021 to April 2022. Bangladeshi university students over the age of 18 and having an internet connection was included in the study. A binary logistic regression analysis along with Pearson's Chi-square test were used to identify COVID-19 vaccine-related side effects predictors after receiving the first dose.

Results

A total of 1,176 participants responded voluntarily to the online study, and most were vaccinated. More than half of the participants received the Sinopharm vaccine (56.5%), while others received Covishield (8.9%), Moderna (7.3%), and Pfizer (5.8%) vaccine. Around 32% of the participants reported side effects after receiving the first dose of the vaccine, including pain and edema (78.4%), body temperature (20.3%), and headache (14.5%), while a few experienced allergy, anxiety, and uneasy feelings. About 17% of the participants reported experiencing side effects after the second dose of the vaccine, including pain and edema (7.5%), body temperature (8.8%), and headache (7.3%). Most side effects were significantly associated with the Moderna vaccine (p < 0.001). Female students and those previously infected with COVID-19 were significantly associated with the side effects after taking the first dose of the vaccine.

Conclusion

We found that side effects are mild and did not pose a significant challenge to Bangladesh's effort in managing and reducing the risk associated with the COVID-19 pandemic.

Impact of SARS-CoV-2 Vaccination or Infection on the Safety and Efficacy of Aesthetic Injections: A Systematic Review

BACKGROUND

Aesthetic injections have become increasingly popular for maintaining a youthful appearance. However, with the rise of SARS-CoV-2, there have been concerns about potential complications. This study aims to summarize and understand the complications that occur in individuals who have received cosmetic injections after SARS-CoV-2 infection or vaccination. By doing so, we hope to provide recommendations to minimize these complications and ensure the safety of aesthetic treatments in the current COVID-19 era.

METHODS

The PRISMA guidelines, the Preferred Reporting Program for Systematic Reviews and Meta-Analyses, were used for this review. Databases including PubMed, EMBASE, Medline, Web of Science and ScienceDirect were searched. The last search time of each database was May 10, 2023. In addition, relevant references were manually searched.

RESULTS

A total of 26 studies containing 139 patients were searched. The complication with the highest percentage of reported patients was delayed inflammatory response (DIR) (n = 68; 48.92%), followed by diminished efficacy (n = 45; 32.37%) and filler reaction (n = 12; 8.63%). The remaining complications include hypersensitivity reactions, symptomatic hypercalcemia, sub-acute hypersensitive reactions, hyperalgesia, infection, fat necrosis and granulomatous reaction.

CONCLUSIONS

Cosmetic injectable procedures are generally safe but may have adverse effects, particularly during the pandemic. It is important for individuals to fully understand these risks beforehand. Clinicians should be knowledgeable about adverse event mechanisms and management to prevent issues. Industry leaders should strengthen risk management efforts to ensure safe and steady development of cosmetic injections. Overall, a comprehensive understanding, effective communication and risk management are crucial for the safe use of cosmetic injectable procedures.

Risk Factors Associated with Cutaneous Reactions Following COVID-19 Vaccine Immunisation: A Registry-Based Case-Control Study

Background

In Malaysia, following extensive COVID-19 vaccination, Hospital Kuala Lumpur reported an increase in cutaneous reactions post-immunisation. To understand this, a case-control study was initiated to identify potential risk factors.

Methods

This registry-based, unmatched case-control study encompasses all adverse event following immunisation (AEFI) reports associated with COVID-19 vaccines, received by the Department of Pharmacy at Hospital Kuala Lumpur through the Malaysian Adverse Drug Reactions Advisory Committee (MADRAC) AEFI reporting forms. Twenty-four potential risk factors were evaluated, including demographic information, medical history, food allergies, COVID-19 vaccination history and prior SARS-CoV-2 infection, were evaluated using MADRAC AEFI reporting forms. Odds ratio (OR) with 95% confidence interval (CI) were estimated using univariable and multivariable logistic regression.

Results

Cutaneous reactions were more frequent in middle-aged females, especially after the first COVID-19 vaccine dose. These reactions, primarily mild and generalised, included pruritus and urticaria. Notably, 52% were delayed reactions (more than 4 h post-vaccination). Factors associated with increased risk of cutaneous reaction following COVID-19 immunisation included history of seafood and shellfish allergy (adjusted odds ratio [adjOR]: 2.11; 95% CI: 1.12, 3.96; P = 0.020), history of vaccine allergy (adjOR: 4.07; 95% CI: 1.44, 11.54; P = 0.008), past dermatological diseases (adjOR: 5.48; 95% CI: 2.03, 14.78; P = 0.001), and past medication allergy (adjOR: 2.12; 95% CI: 1.36, 3.31; P = 0.001).

Conclusion

Self-reported histories of allergies to vaccines, foods or medications were found to increase the likelihood of cutaneous reactions following COVID-19 vaccination. These reactions, which were predominantly mild, did not hinder the administration of the second vaccine dose. The majority of reactions occurred after the first dose, manifesting as generalised pruritus and urticaria. They were effectively managed with oral antihistamines and low-dose corticosteroids, thereby avoiding the need for hospitalisation.

Cutaneous adverse reactions associated with COVID-19 vaccines: Current evidence and potential immune mechanisms

As the number of vaccinated individuals has increased, there have been increasing reports of cutaneous hypersensitivity reactions. The main COVID-19 vaccines administered include messenger ribonucleic acid vaccines, non-replicating viral vector vaccines, inactivated whole-virus vaccines, and protein-based vaccines. These vaccines contain active components such as polyethylene glycol, polysorbate 80, aluminum, tromethamine, and disodium edetate dihydrate. Recent advances in understanding the coordination of inflammatory responses by specific subsets of lymphocytes have led to a new classification based on immune response patterns. We categorize these responses into four patterns: T helper (Th)1-, Th2-, Th17/22-, and Treg-polarized cutaneous inflammation after stimulation of COVID-19 vaccines. Although the association between COVID-19 vaccination and these cutaneous adverse reactions remains controversial, the occurrence of rare dermatoses and their short intervals suggest a possible relationship. Despite the potential adverse reactions, the administration of COVID-19 vaccines is crucial in the ongoing battle against severe acute respiratory syndrome coronavirus 2.

Exploring cutaneous lymphoproliferative disorders in the wake of COVID-19 vaccination

Background

Individual reports have described lymphoproliferative disorders (LPDs) and cutaneous lymphomas emerging after administration of the COVID-19 vaccine; however, the relationship between reactions and vaccine types has not yet been examined.

Objective

Determine if there are cases of cutaneous LPDs associated with certain COVID-19 vaccines and their outcomes.

Methods

We analysed PubMed, the Vaccine Adverse Events Reporting System (VAERS), and our database for instances of biopsy-proven LPDs following COVID-19 vaccines.

Results

Fifty cases of biopsy-proven LPDs arising after COVID-19 vaccination were found: 37 from medical literature, 11 from VAERS and two from our institution. Geographical distribution revealed the most cases in the United States, Italy, and Greece, with single cases in Spain, Colombia, Canada, Japan, and Romania. The average age of patients was 53; with a slight male predominance (male-to-female ratio of 1.5:1). The Pfizer-BioNTech vaccine was associated with LPDs in 36/50 (72%) cases, aligning with its 70% share of the global vaccine market. Histopathology revealed CD30+ in 80% of cases. The most prevalent form of LPD was lymphomatoid papulosis (LyP, 30%). All reported cases produced favourable outcomes (either complete or near-complete remission). Therapeutic approaches ranged from observation to treatment with steroids, methotrexate, or excision.

Conclusion

LPDs after COVID-19 vaccination appear in the context of the same vaccines (proportionally to their global market shares), share clinical and pathological findings, and have indolent, self-limited character.

Viral reactivation following COVID-19 vaccination: a review of the current literature

Currently, four vaccines for COVID-19 have been licensed by the European Medicines Agency: two viral vector-based vaccines and two mRNA-based vaccines. Since their approval, several cutaneous reactions related to vaccination have been reported in the literature. Among these, viral reactivations are one of the most frequent. The aim of this article was to investigate the current literature regarding viral reactivations following COVID-19 vaccination, focusing attention on pityriasis rosea (PR), herpes zoster and herpes simplex. A comprehensive literature search using various databases was performed and we included metanalyses, reviews, letters to the editor, real-life studies, case series and reports. A total of 48 articles involving 2067 patients were selected. Of these, 32, 6 and 17 articles reported varicella zoster virus (VZV) reactivation (1758 patients), herpes simplex virus (HSV) (238 patients) onset and PR (71 patients), respectively (some articles discussed more than one of these three reactivations). Possible pathogenetic mechanisms underlying viral reactivation are still not understood. Also, the possible correlations between vaccination and viral reactivation should be clarified. Certainly, vaccination should not be discouraged.

Ultrasonographic features of nonvascular complications of hyaluronic acid fillers: a retrospective study at a reference center for dermatologic ultrasonography

Hyaluronic acid filler injections have been associated with early, temporary, and delayed-onset complications. High-resolution ultrasound with Doppler analysis has been increasingly used to detect and identify such complications. We comprehensively describe the most common ultrasonographic findings of nonvascular complications associated with hyaluronic acid filler injections. This retrospective, cross-sectional, observational study was conducted at a reference center for dermatologic ultrasound in Bogotá, Colombia. Ultrasound reports documented the ultrasonographic findings of nonvascular complications of hyaluronic acid filler injections. Fifty-two complications were documented in a cohort of 50 patients (women, 88%). The infraorbital region was the most common site affected (23%), followed by the nasolabial region (22%). The Tyndall effect was the most common complication (25% of all), followed by changes in rheology (21%) and pseudosarcoidal (foreign body granuloma) reaction (15%). The Tyndall effect stood out for its distinctive ultrasonographic characteristics. We discuss the ultrasonographic findings and pathogenesis of other complications, including filler migration, early hypersensitivity, aseptic abscess, overcorrection, and filler material interaction. The clinical presentation of hyaluronic acid filler complications can be confusing, delaying timely diagnosis and treatment. High-resolution ultrasound with Doppler analysis is a valuable tool for avoiding unnecessary treatments and ensuring timely diagnosis and treatment.

Improving Clinical Practice Through Patient Registries in Allergy and Immunology

Patient registries are a mechanism for collecting data on allergic and immunologic diseases that provide important information on epidemiology and outcomes that can ultimately improve patient care. Key criteria for establishing effective registries include the use of a clearly defined purpose, identifying the target population and ensuring consistent data collection. Registries in allergic diseases include those for diseases such as inborn errors of immunity (IEI), food allergy, asthma and anaphylaxis, pharmacological interventions in vulnerable populations, and adverse effects of pharmacologic interventions including hypersensitivity reactions to drugs and vaccines. Important insights gained from patient registries in our field include contributions in phenotype and outcomes in IEI, the risk for adverse reactions in food-allergic patients in multiple settings, the benefits and risk of biologic medications for asthma during pregnancy, vaccine safety, and the categorization and genetic determination of risk for severe cutaneous adverse reactions to medications. Impediments to the development of clinically meaningful patient registries include the lack of funding resources for registry establishment and the quality, quantity, and consistency of available data. Despite these drawbacks, high-quality and successful registries are invaluable in informing clinical practice and improving outcomes in patients with allergic and immunological diseases.

The impact of COVID-19 vaccine reactions on secondary vaccine hesitancy

BACKGROUND

Primary and booster vaccinations are critical for mitigating COVID-19 transmission, morbidity, and mortality. Future booster vaccine campaigns rely on an increased understanding of vaccine hesitancy.

OBJECTIVE

To evaluate self-reported allergic and skin vaccine reactions as factors potentially associated with vaccine hesitancy in a nationwide vaccine allergy registry.

METHODS

Responses to survey questions concerning COVID-19 vaccine perceptions, coded from free text by 2 independent reviewers. Multivariable logistic regression models were used to determine the association between changed negative perception and respondent demographics, vaccination history, and reaction characteristics.

RESULTS

A total of 993 individuals (median of 46 years [IQR, 36-59], 88% female, 82% White) self-reported reactions to COVID-19 vaccination. Reactions included the following: delayed large local skin reaction (40%), hives/urticaria (32%), immediate large local skin reaction (3%), swelling (3%), anaphylaxis (2%), and other or unspecified (20%). Most respondents were initially unconcerned about the safety of COVID-19 vaccines (56%). After reactions, 401 of 993 (40%) report negative change in perception of vaccination, with more than half of these respondents (n = 211, 53%) citing their reasoning as a negative experience with adverse effects. Of 102 individuals asked about future vaccination, 79 (77%) indicated that they were unlikely or very unlikely to receive future COVID-19 vaccinations. Increased negative perception after reaction was associated with younger age, later COVID-19 vaccination dose number, and reaction type.

CONCLUSION

Our findings reveal that an individual's experience with allergic or cutaneous adverse effects after COVID-19 vaccination affects attitudes and decision-making regarding future vaccination, even in initially non-hesitant individuals. Further investigation of secondary vaccine hesitancy is necessary for adapting public health messaging to this important population.

New Onset and Exacerbation of Autoimmune Bullous Dermatosis Following COVID-19 Vaccination: A Systematic Review

BACKGROUND

Cases of autoimmune bullous dermatosis (AIBD) have been reported following COVID-19 vaccination.

OBJECTIVE

We aimed to provide an overview of clinical characteristics, treatments, and outcomes of AIBDs following COVID-19 vaccination.

METHODS

We conducted a systematic review and searched the Embase, Cochrane Library, and Medline databases from their inception to 27 March 2024. We included all studies reporting ≥ 1 patient who developed new-onset AIBD or experienced flare of AIBD following at least one dose of any COVID-19 vaccine.

RESULTS

We included 98 studies with 229 patients in the new-onset group and 216 in the flare group. Among the new-onset cases, bullous pemphigoid (BP) was the most frequently reported subtype. Notably, mRNA vaccines were commonly associated with the development of AIBD. Regarding the flare group, pemphigus was the most frequently reported subtype, with the mRNA vaccines being the predominant vaccine type. The onset of AIBD ranged from 1 to 123 days post-vaccination, with most patients displaying favorable outcomes and showing improvement or resolution from 1 week to 8 months after treatment initiation.

CONCLUSIONS

Both new-onset AIBD and exacerbation of pre-existing AIBD may occur following COVID-19 vaccination. Healthcare practitioners should be alert, and post-vaccination monitoring may be essential.

Antiphospholipid syndrome in the era of COVID-19 - Two sides of a coin

In addition to the respiratory symptoms associated with COVID-19, the disease has consistently been linked to many autoimmune diseases such as systemic lupus erythematous and antiphospholipid syndrome (APS). APS in particular was of paramount significance due to its devastating clinical sequela. In fact, the hypercoagulable state seen in patients with acute COVID-19 and the critical role of anticoagulant treatment in affected individuals shed light on the possible relatedness between APS and COVID-19. Moreover, the role of autoimmunity in the assumed association is not less important especially with the accumulated data available regarding the autoimmunity-triggering effect of SARS-CoV-2 infection. This is furtherly strengthened at the time patients with COVID-19 manifested antiphospholipid antibodies of different types following infection. Additionally, the severe form of the APS spectrum, catastrophic APS (CAPS), was shown to have overlapping characteristics with severe COVID-19 such as cytokine storm and multi-organ failure. Interestingly, COVID vaccine-induced autoimmune phenomena described in the medical literature have pointed to an association with APS. Whether the antiphospholipid antibodies were present or de novo, COVID vaccine-induced vascular thrombosis in certain individuals necessitates further investigations regarding the possible mechanisms involved. In our current paper, we aimed to focus on the associations mentioned, their implications, importance, and consequences.

New-onset or flare-up of bullous pemphigoid associated with COVID-19 vaccines: a systematic review of case report and case series studies

Background

Numerous cutaneous manifestations have been associated with the Coronavirus Disease 2019 (COVID-19) outbreak and vaccination, but new-onset bullous pemphigoid (BP) or flaring up of pre-existing BP is a rare side effect of COVID-19 vaccines that has been mentioned to a lesser extent in the literature. Therefore, we aimed to conduct a systematic review focused on the association between the new- onset or flare-up of BP and the COVID-19 vaccination.

Method

A comprehensive literature search was conducted using PubMed (MEDLINE), Scopus, and the Web of Science databases up to 11 March 2023. The search aimed to identify English-language studies reporting new-onset or flare-ups of BP as a potential side effect of the COVID-19 vaccination. The search terms included bullous pemphigoid and COVID-19 vaccination-related MeSH terms.

Results

The systematic review of 40 articles investigating the incidence of BP in individuals who received various COVID-19 vaccines revealed pertinent findings. Among the 54 patients with new-onset BP, the median age was 72.42 years, and most were men (64%). Conversely, the median age of the 17 patients experiencing a flare-up of BP was 73.35 years, with a higher proportion of women (53%). Regarding vaccination types, a significant number of patients (56%) developed new-onset BP after receiving the BNT162b2 vaccine (Pfizer-BioNTech).

Conclusion

This study indicates a potential association between COVID-19 vaccinations, particularly mRNA vaccines, and the occurrence of BP. It suggests that this rare autoimmune disorder may be triggered as an adverse event following the COVID-19 vaccination. However, it is important to note that the majority of BP patients in our study were unaffected by the COVID-19 vaccine, and even those who experienced worsening of their conditions were managed without significant consequences. These findings provide additional evidence supporting the safety of COVID-19 vaccines. Physicians should be mindful of this uncommon adverse event and encourage patients to complete their planned vaccination schedules.

Multicentric observational study of the possible side effects of the COVID-19 vaccine in relation to absorbable thread insertion

Background

Coronavirus disease 2019 (COVID-19) vaccination programs in Europe began in December 2020, and as the number of vaccinated people increased, more information emerged about the possible side effects of vaccines. Recently, some reports appeared around the association of adverse reactions following soft-tissue filler injections and the COVID-19 vaccines. This fact raised the concerns of esthetic practitioners regarding the possibility of the association of the COVID-19 vaccine and adverse effects in other esthetic treatments. Many of us wonder if botox injection, biostimulation, or other procedure could trigger the same or other adverse reactions after the COVID-19 vaccination. Many colleagues postpone esthetic treatments, canceling the appointments.

Objective

The objective of our investigation was to understand if any adverse reactions have been observed in the patients who underwent threads implantation before and after the vaccination.

Materials and Methods

Four medical centers have collected the data of the patients treated with absorbable threads before the vaccination and after vaccination for COVID-19. The dossiers of 190 patients with a mean age of 50.4 years were evaluated. Three questionnaires were administered 1 week, 1 month, and 3 months after thread implantation.

Results

There were no adverse reactions in the groups of patients under monitoring. Only one patient presented signs of inflammation and infection, but they are more probably attributable to the contamination during thread insertion.

Conclusions

No patients treated with absorbable threads developed adverse events in relation to the COVID-19 vaccine. The only case of inflammation is attributable probably to the contamination of the thread during the procedure.

Cutaneous Reactions after COVID-19 Vaccines: Analysis of the Clinical and Histopathological Spectrum-Case Series and Review of the Literature

(1) Background: Various cutaneous adverse drug reactions (ADRs) are observed with the implementation of mRNA COVID-19 vaccines. To gain insight into the clinicopathologic features, we analyzed the correlation of histological and clinical data in 48 patients with these ADRs. (2) Methods: Single-center retrospective study in patients with ADRs after mRNA COVID-19 vaccination (mRNA-1273 and BNT162b2 vaccines). (3) Results: Distant generalized ADRs prevailed (91%), often appearing clinically as spongiotic dermatitis or maculopapular exanthema. Histopathological analysis revealed spongiotic changes (46%) and dermal superficial perivascular predominantly lymphocytic infiltrates (17%). Eosinophils were found in 66% of biopsies, neutrophils in 29%, and plasma cells only in 8% of biopsies. Most ADRs occurred after the second vaccine dose (44%). Histologically spongiotic changes were associated with clinical features of spongiotic dermatitis in only 50% of patients and maculopapular exanthema in the remaining patients. ADRs represented an aggravation of preexisting skin disease in 23% of patients. ADRs regressed within 28 days or less in 53% of patients and persisted beyond a month in the remaining patients. (4) Conclusions: Our study demonstrates a diverse spectrum of generalized ADRs, revealing correlations between histology and clinical features but also instances of divergence. Interestingly, in about half of our patients, ADRs were self-limited, whereas ADRs extended beyond a month in the other half.

Pityriasis following COVID-19 vaccinations: a systematic review

In the wake of a global COVID-19 pandemic, where innovations in vaccination technology and the speed of development and distribution have been unprecedented, a wide variety of post-vaccination cutaneous reactions have surfaced. However, there has not been a systematic review that investigates pityriasis eruptions and the associated variants following COVID-19 inoculations. A PubMed search using Preferred Reporting Items for Systematic Reviews and Meta-Analyses was performed to find case reports from the earliest record through November 2022. Data including types of vaccination and pityriasis were extracted and a quality review was performed; 47 reports with 94 patients were found: 64.9% had pityriasis rosea (PR), 3.2% PR-like eruptions, 16.0% pityriasis rubra pilaris, 7.4% pityriasis lichenoides et varioliformis acuta, 3.2% pityriasis lichenoides chronica, and 5.3% had reactions described as atypical. The top three COVID-19 vaccinations reported were Pfizer-BioNTech (47.9%), Oxford-AstraZeneca (11.7%), and Moderna (8.5%). Pityriasis reactivity was reported most frequently after the Pfizer-BioNTech vaccination, with pityriasis rosea being the most common variant. A large difference was additionally found between the ratio of post-vaccination pityriasis reactions following Pfizer and Moderna vaccinations (5.63), and the ratio of Pfizer's usage in the United States as of December 28, 2022 relative to that of Moderna (1.59). Further studies with adequate follow-up periods and diagnostic testing will thus need to be performed to elucidate the root of this discrepancy and better characterize the association between different pityriasis reactions and COVID-19 vaccinations.

The Impact of the COVID-19 Pandemic on the Incidence of Herpes Zoster: A Narrative Literature Review

Coronavirus disease 2019 (COVID-19) has had a broad impact on health services and health outcomes. During the pandemic, there were numerous reports of herpes zoster (HZ) in people with COVID-19 and in COVID-19 vaccine recipients. The aim of this review is to elucidate the global effects of the COVID-19 pandemic on HZ. It is postulated that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection produces an immunosuppressive state that favours varicella zoster virus (VZV) reactivation. Three large cohort studies (a multinational study and studies from the USA and Spain) that excluded individuals vaccinated against HZ reported significantly increased risk of HZ following COVID-19 infection, especially in people aged ≥ 50 years. In contrast, a large study from Israel that did not consider HZ vaccination status reported no such increase. Cases of HZ following COVID-19 vaccination have been reported and may be the result of attenuated cell-mediated immunity. This phenomenon appears to vary by vaccine type. Some (but not all) large analyses have reported a significant positive relationship between receipt of mRNA vaccines for COVID-19 and development of HZ. These include analyses of health records databases in Israel and Hong Kong and of spontaneous case reports in the US Vaccine Adverse Event Reporting System (VAERS) database. Routine vaccinations, including shingles vaccine programmes, were disrupted by the COVID-19 pandemic. It is estimated that missed shingles vaccinations may have resulted in 63,117 avoidable HZ cases in the USA. Now that the World Health Organization has declared an end to the COVID-19 pandemic as a health emergency and routine vaccination services have resumed, there is a need to increase awareness of HZ and HZ vaccination.Graphical abstract available for this article.

Primary cutaneous marginal zone lymphoproliferative disorder following COVID-19 vaccination

During the coronavirus disease 2019 (COVID-19) pandemic, COVID-19 vaccines were administered worldwide. A number of skin reactions, including primary cutaneous T-cell lymphoproliferative disorders (LPDs) were reported following COVID-19 vaccination. We report a case of primary cutaneous marginal zone lymphoproliferative disorder (PCMZLPD) secondary to COVID-19 vaccination. A 57-year-old man presented with an erythematous nodule on his left arm at the site of vaccine inoculation following his first dose of the Moderna (mRNA-1273) vaccine a few weeks prior. The nodule continued to progress in size after the second dose. A skin biopsy specimen of the nodule showed a diffuse dermal infiltrate of small to medium-sized lymphocytes with plasma cells and histiocytes. The infiltrate was composed of CD3+ T cells with CD20+ and CD79a+ B cells. The neoplastic B cells reacted with BCL-2 and were negative for BCL-6 and CD10. Kappa light chain restriction was identified by in situ hybridization. Gene rearrangement studies revealed kappa light chain monoclonality, confirming the diagnosis of PCMZLPD. The temporal association with the Moderna vaccination and the occurrence of the lesion at the inoculation site indicate a COVID-19 vaccination-induced PCMZLPD. This is one of the rare cases of PCMZLPD following COVID-19 vaccination.

Pityriasis Rosea Eruption Following the Administration of Oxford-AstraZeneca Vaccine

The coronavirus disease 2019 (COVID-19) infection has led to accelerated development and utilization of vaccines to prevent its implications on health. One of these vaccines is a vector-based, Oxford-AstraZeneca Vaccine (AZD1222). Frequently reported side effects are related to host-immune response. While dermatologic manifestation is peculiar in nature and denotes a serious eruption that might defer future vaccination. Herein, we present a case of a medically free 37-year-old female who developed clinical and histological evidence of pityriasis rosea (PR) after administration of a second-dose vaccination of AZD1222. The first dose of vaccination was administered as Pfizer BioNTech COVID-19 mRNA (BNT162b2) vaccine. This case is unique in nature as this patient developed AZD1222-induced PR, while some reports in the literature have linked PR to the BNT162b2 vaccine. This patient continued to receive a booster vaccination with BNT162b2 with no reportable side effects.

Steroidal lactones from Withania somnifera effectively target Beta, Gamma, Delta and Omicron variants of SARS-CoV-2 and reveal a decreased susceptibility to viral infection and perpetuation: a polypharmacology approach

Prevention from disease is presently the cornerstone of the fight against COVID-19. With the rapid emergence of novel SARS-CoV-2 variants, there is an urgent need for novel or repurposed agents to strengthen and fortify the immune system. Existing vaccines induce several systemic and local side-effects that can lead to severe consequences. Moreover, elevated cytokines in COVID-19 patients with cancer as co-morbidity represent a significant bottleneck in disease prognosis and therapy. Withania somnifera (WS) and its phytoconstituent(s) have immense untapped immunomodulatory and therapeutic potential and the anticancer potential of WS is well documented. To this effect, WS methanolic extract (WSME) was characterized using HPLC. Withanolides were identified as the major phytoconstituents. In vitro cytotoxicity of WSME was determined against human breast MDA-MB-231 and normal Vero cells using MTT assay. WSME displayed potent cytotoxicity against MDA-MB-231 cells (IC50: 66 µg/mL) and no effect on Vero cells in the above range. MD simulations of Withanolide A with SARS-CoV-2 main protease and spike receptor-binding domain as well as Withanolide B with SARS-CoV spike glycoprotein and SARS-CoV-2 papain-like protease were performed using Schrödinger. Stability of complexes followed the order 6M0J-Withanolide A > 6W9C-Withnaolide B > 5WRG-Withanolide B > 6LU7-Withanolide A. Maximum stable interaction(s) were observed between Withanolides A and B with SARS-CoV-2 and SARS-CoV spike glycoproteins, respectively. Withanolides A and B also displayed potent binding to pro-inflammatory markers viz. serum ferritin and IL-6. Thus, WS phytoconstituents have the potential to be tested further in vitro and in vivo as novel antiviral agents against COVID-19 patients having cancer as a co-morbidity.

BioNTech COVID-19 (BNT162b2) Vaccination and Varicella Zoster Reactivation: A Comprehensive Cross-sectional Study

Herpes zoster (HZ) results from reactivation of latent varicella-zoster virus. Recent observations have suggested that HZ is associated with vaccination against COVID-19. To investigate the association between the vaccine and HZ severity, a single-centre, cross-sectional study of all patients diagnosed with HZ and 2 control diagnoses (cellulitis and bone fractures), between 2017 and 2021, was performed. Hospital visits and hospitalization rates were compared. All medical records of patients diagnosed with HZ in the first year after the COVID-19 vaccination campaign began were reviewed, in order to generate a retrospective cohort comparing vaccinated and unvaccinated patients with HZ. All participants had received the Pfizer-BioNTech COVID-19 (BNT162b2) vaccine. During the study period, 2,413 patients were diagnosed with HZ, and when normalized to control diagnoses the number of cases remained stable. The retrospective cohort included 365 patients. A multivariate analysis controlling for sex, age, autoimmune diseases, malignancies, and immunosuppressive therapy showed higher admission rates in vaccinated compared with unvaccinated individuals (odds ratio (OR) 2.75, 95% CI 1.27-5.96, p = 0.01). However, matching techniques and stratification by age, used to better control for confounders, invalidated these findings. No differences were observed in other variables indicative of disease severity (hospital stay length and complications). In conclusion, COVID-19 vaccination was not found to be associated with an increased risk of HZ-related admission and complications.

Oral manifestations after vaccinations: A systematic review of observational studies

OBJECTIVE

This study aimed to assess the prevalence and types of oral adverse events following immunization (AEFIs) in people who received at least one dose of any type of vaccine.

MATERIALS AND METHODS

We conducted a bibliographic search about oral AEFIs in MEDLINE, Embase, PubMed, and Ovid from database inception to November 07, 2022. Risk of bias was assessed using the MURAD or the Quality In Prognosis Studies tools. Random-effects proportional meta-analysis was applied.

RESULTS

A total of 119 studies involving 343 people were eligible. These reported AEFIs occurred following administration of the coronavirus disease 2019 vaccine, anti-influenza vaccine, hepatitis B vaccine, and anti-smallpox vaccine. The most common to be affected in vaccinated people were buccal mucosa (63.1%; 95% confidence interval (CI) 33.4-88.2) and lips (55.7%; 95% CI, 41.1-69.8). The most prevalent oral AEFIs were ulceration (55.2%; 95% CI 24.4-84.0), swelling (65.2%; 95% CI 34.9-89.8), and burning sensation (18.3%; 95% CI 7.9-31.8).

CONCLUSIONS

The mechanisms underlying oral AEFIs should be further investigated to promptly recognize oral manifestations and provide optimal management for people undergoing vaccination.

Increased prevalence of erythema multiforme in patients with COVID-19 infection or vaccination

Several reports stated that erythema multiforme (EM) was associated with COVID-19 with detrimental outcomes in patients. However, since most of these are case reports, it is challenging to quantitively assess their associations. Therefore, our study aims to determine the prevalence of EM in the context of COVID-19. The study was designed as a retrospective cross-sectional hospital-based study of registered patients at the University of Florida Health Hospital. The ICD-10 codes for EM, COVID-19 infection, and COVID-19 vaccines were searched in the database. The odds ratio was calculated to assess the risk of EM after COVID-19 infection or vaccination. Our study included 43,547 patients with a history of COVID-19 infection, of whom 92 developed EM. Patients with COVID-19 infection were 6.68 times more likely to have EM than those without COVID-19 (P < 0.0001). Similarly, the risk of developing EM after COVID-19 vaccination was 2.7, significantly higher than the general population (P < 0.0001). The prevalence of EM following COVID-19 infection or vaccination significantly differs from the general population, highlighting the importance of monitoring patients for EM after COVID-19 infection and/or vaccination. It is imperative to disseminate awareness to clinicians and patients regarding the impact of COVID-19 on EM.

An 82-year-old man with new skin lesions after COVID-19 vaccination

Background: During the height of the SARS CoV-2 (severe acutre respiratory syndrome coronavirus disease 2019 [COVID 19]) pandemic, there have been numerous case reports of cutaneous reactions shortly after COVID-19 vaccine administration. Most reported cases are local injection-site reactions, whereas persistent or delayed cutaneous reactions have not been as common. Methods: We present the case of an 82-year-old man with persistent rash after the second COVID-19 vaccination. Results: A specific diagnosis was confirmed after the third skin biopsy. Conclusion: Patients are frequently referred to an allergist for various cutaneous reactions that occurred after vaccination, concerned about a possible drug allergy. This case emphasizes the importance of keeping a broad differential diagnosis when encountering a persistent skin rash not resolved by oral antihistamines or steroids.

Interesting Mucocutaneous Manifestations in COVID-19 Infection or Vaccination Confirmed by Histopathology: A Case Series

Introduction

Mucocutaneous complications or adverse events due to SARS-CoV-2 infection or vaccination have been well delineated in the literature, respectively. Most eruptions are considered mild and self-limiting; however, for the atypical cases with a tentative clinical diagnosis, performing a biopsy and histopathological assessment is pivotal to confirm the diagnosis and subsequently prescribe a more tailored treatment. Despite the diverse reporting of such incidents globally, most studies restrict the rate of biopsied cases to less than 15%.

Case Presentations

This case series elucidates 20 patients referred to the tertiary dermatology clinic, including 14 COVID-19 infection-related eruptions such as lichen planus (LP), cutaneous vasculitis, pityriasis rosea (PR), discoid lupus erythematosus, guttate psoriasis, sarcoidosis, Raynaud's phenomenon, non-specific lesions resembling genital warts, Beau's line, and one severe case of purpura fulminans with a promising outcome. Moreover, we presented six vaccine-induced cases comprising LP, urticarial vasculitis, PR, parapsoriasis, and localized morphea. The diagnosis of all challenging cases has been proven by histopathological evaluation. We included pertaining anamnesis details of each patient and vivid classifying images to pinpoint the morphologic features of each condition.

Discussion

In line with our previous studies, the vaccine-induced eruptions were less severe compared to infection-related complications of COVID-19 and are mostly controllable by antihistamines and corticosteroid administration. Therefore, reporting such events should not impede COVID-19 vaccination in the general population.

Global Scientific Overview of Dermatology Related to COVID-19: A Bibliometric Analysis

Background

Coronavirus disease 2019 (COVID-19) has had a significant impact on dermatology, but to date no bibliometric analysis of this field has been identified. Therefore, the aim of this study was to perform a bibliometric indicator analysis of the worldwide scientific production of COVID-19 in dermatology.

Materials and Methods

An advanced bibliographic search was performed in the Scopus database to identify articles on COVID-19 and dermatology from 2020 to 2021. The collected information was analysed with SciVal software. Bibliometric data were described through figures and summary tables.

Results

A total of 1448 documents were collected and analysed. Torello Lotti was the author with the greatest scientific production; however, Esther Freeman had the greatest impact. Harvard University was the institution with the highest number of published articles. Most papers were published in the first quartiles. The United States and Italy were the leading countries in terms of production. Articles with international collaboration had the highest impact.

Conclusion

Articles related to dermatology and COVID-19 are mostly published with American and Italian affiliations. In addition, there has been an increase in the distribution of articles published in the first quartile, which would reflect a growing interest in the community. Publications with international collaboration reported the highest impact, so future authors should take this into account.

Cutaneous lymphoproliferative disorders after COVID-19 vaccination: clinical presentation, histopathology, and outcomes

Individual reports described lymphoproliferative disorders (LPDs) after COVID-19 vaccination; however, the relationship between cases is unexamined. We aim to determine if there are cases of cutaneous LPDs associated with COVID-19 vaccination and their outcomes. We present a review of world literature, vaccine registries, and two unreported cases of LPDs after COVID-19 vaccination. Review of the medical literature, VAERS, and our two cases reveal predominance of Pfizer-BioNTech vaccine, younger patients, and males. All cases resulted in favorable outcomes. Approximately 84% of cases demonstrated CD30+ positivity in their skin biopsies, suggesting that an antigenic trigger may lead to a type IV adaptive immune response, with clonal expansion of CD30+ T-cells and subsequent oncogenic mutational hits eventuating in transient LPDs. LPDs after COVID-19 vaccination appear in the context of the same vaccines (proportionally to their global market shares), share clinical and pathological findings, and have indolent, self-limited character.

Latent Mastocytosis Triggered by COVID-19 Vaccination: A Case Report

BACKGROUND

Hereby, we describe the first case of latent mastocytosis triggered by mRNA-based vaccine to prevent COVID-19 infection.

CASE PRESENTATION

In a 42-year-old Arabian man affected by slight, undiagnosed mastocytosis, the second dose of the COVID-19 vaccine made more blatant his latent disease. The postvaccination diagnostic iter is illustrated and the potential reasons causing the onset of the cutaneous mastocytosis are discussed.

CONCLUSION

Clinicians should keep a longer follow-up of their patients after the COVID-19 vaccination, not related to few hours, for the risk of immediate-type adverse events only.

The role of lymphocyte transformation tests (LTT) in suspected severe delayed hypersensitivity reactions following COVID-19 vaccination

Coronavirus (COVID-19) vaccines have proved to be effective in the pandemic response but can cause adverse events such as delayed hypersensitivity reactions (DHRs). Delayed-reading intradermal tests (IDT) to vaccines are limited by false-positive results and may reflect a cell-mediated rather than IgE-mediated immune response. Lymphocyte transformation test (LTT), which has been utilized in the diagnosis of drug allergy, may be helpful in suspected COVID-19 vaccine and/or its excipient-related DHRs. To investigate the use of LTT in two suspected cases of COVID-19 vaccine-induced DHRs, two patients with suspected DHRs to COVID-19 vaccination were tested by delayed-reading IDT and LTT against vaccines and their excipients. A 47-year-old man developed acute mixed-pattern hepatitis after the second dose of ChAdOx1 vaccine. LTT performed at 2 months post-vaccination revealed reactivity to the ChAdOx1 vaccine, polysorbate 80 and mildly to PEG 2050 but not BNT162b2 vaccine. Delayed-reading IDT returned negative to both vaccines and excipients. He tolerated BNT162b2 vaccination with no adverse events. A 36-year-old woman presented with subacute morbilliform eruption and hepatitis after the first dose of BNT162b2 vaccine. LTT performed 3 months later revealed reactivity to the BNT162b2 but not PEG 2050. Repeat LTT following subsequent natural Severe Acute Respiratory Coronavirus-2 (SARS-CoV-2) infection revealed reactivity to ChAdOx1 and NVX-CoV2373 vaccines but not polysorbate 80. Delayed-reading IDT remained negative. She proceeded with NVX-CoV2373 vaccination with no symptom recurrence. LTT may be a useful tool in suspected COVID-19 vaccine-related DHRs. Further evaluation with a larger patient cohort is required.

Herpes Zoster after COVID-19 Infection or Vaccination: A Prospective Cohort Study in a Tertiary Dermatology Clinic

Background

Herpes zoster (HZ) has been observed to occur after COVID-19 infection and vaccination; however, knowledge regarding the demographic data, clinical presentations, and treatment outcomes of HZ is limited.

Objective

To compare the demographic data, clinical manifestations, treatments, and outcomes of patients with and without HZ within 14 days of COVID-19 infection or vaccination.

Methods

This prospective cohort study involving patients diagnosed with cutaneous HZ was conducted at a dermatology clinic from October 2021 to January 2023.

Results

Among a total of 232 patients with HZ, the median age was 62.0 years and 59.1% were female. HZ developed in 23 (9.9%) and four (1.7%) patients after COVID-19 vaccination and infection, respectively. The mean duration from vaccination and the median duration from infection to HZ onset were 5.7 and 8.5 days, respectively. The proportion of female patients was significantly higher in the group of patients with COVID-19 vaccination or infection than in those without such a history (P = 0.035). Patients who developed HZ following the recent COVID-19 infection had a median age of 42.5 years, which was lower than that of the other groups. Dissemination occurred in 8.7% of the patients after COVID-19 vaccination. HZ recurrence was reported in five cases, of which 80% had been vaccinated or infected with COVID-19 during the previous 21 days. All patients had similar durations of antiviral treatment, crust-off time, and duration of neuralgia.

Conclusions

HZ after COVID-19 vaccination is more frequently observed in females, while HZ after COVID-19 infection tends to occur in younger patients. Disseminated HZ is more common in patients recently vaccinated against COVID-19. COVID-19 vaccination or infection may trigger recurrent HZ infection.

Musculoskeletal manifestations of COVID-19

During the COVID-19 pandemic, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected millions of people worldwide, with acute respiratory distress syndrome (ARDS) being the most common severe condition of pulmonary involvement. Despite its involvement in the lungs, SARS-CoV-2 causes multiple extrapulmonary manifestations, including manifestations in the musculoskeletal system. Several cases involving bone, joint, muscle, neurovascular and soft tissues were reported shortly after pandemic onset. Even after the acute infection has resolved, many patients experience persistent symptoms and a decrease in quality of life, a condition known as post-COVID syndrome or long COVID. COVID-19 vaccines have been widely available since December 2020, preventing millions of deaths during the pandemic. However, adverse reactions, including those involving the musculoskeletal system, have been reported in the literature. Therefore, the primary goal of this article is to review the main imaging findings of SARS-CoV-2 involvement in the musculoskeletal system, including acute, subacute, chronic and postvaccination manifestations.

Adverse reactions to cosmetic implants after COVID-19 vaccination: A literature review

BACKGROUND

As the world's population of people vaccinated with the COVID-19 vaccine increases, adverse reactions are increasingly being reported. There have been progressive reports of the effects of COVID-19 vaccination on cosmetic fillers or prostheses, but they have not been reviewed based on their clinical morphologic patterns. This article reviewed the progress of research on adverse reactions to cosmetic implants after COVID-19 vaccination.

METHODS

We researched the English-language literature up to October 15, 2022, using predefined keywords to identify relevant studies about adverse reactions to cosmetic implants after the COVID-19 vaccination, collecting patient characteristics, implant type, the time interval between vaccination and implantation or injection, time of onset, symptoms, treatments, and outcomes.

RESULTS

Among the adverse reactions to implants associated with COVID-19 vaccination, we distinguished between (1) injectable fillers and (2) surgical prosthetic implants. The most common adverse reactions were at the site of hyaluronic acid injection and breast prosthesis after Pfizer vaccination, mainly DIRs, and mainly manifested as edema, rash, fever, and capsular contracture. This paper also reported the possible causes, treatments of DIRs, and limitations of current studies.

CONCLUSIONS

In this article, we attempted to investigate and discuss all the adverse reactions of cosmetic implants related to COVID-19 vaccination in the current literature, to unmask these reactions and make a more accurate assessment of vaccine safety.

Lower Eyelid Complication After Blepharoplasty and COVID-19 Vaccination

BACKGROUND

Following COVID-19 mass vaccination campaign, new- and unknown-related reactions have emerged.

CASE REPORT

Four months after transcutaneous lower blepharoplasty and few days after the second dose of SARS-CoV-2 Pfizer mRNA vaccination, a 57-year-old man developed a bilateral palpebral ecchymosis. While the lesion healed spontaneously on the left side, the ecchymosis on the right lower lid did not regress. It presented swelling and hard consistency, clinically involving only skin layer. No alterations were revealed upon blood tests and instrumental evaluations. Histological examination showed lymphovascular hyperplasia on a probable reactive basis. The lesion was resistant to medical and surgical therapies. After 15 months, it regressed spontaneously.

CONCLUSIONS

In the reported case, an evident chronological relationship exists between surgical site and vaccine reaction, while other etiopathogenetic factors were excluded. This case represents a previously undescribed condition linking postvaccination reaction and long-term surgical outcome.

Dose Intervals and Time since Final Dose on Changes in Metabolic Indices after COVID-19 Vaccination

The rapid development and implementation of COVID-19 vaccines merit understanding its effects on metabolic indices. This retrospective longitudinal study investigated the influence of first-to-second-dose intervals and time since the final dose on the metabolic indices of individuals receiving COVID-19 vaccinations. A total of 318 Saudi subjects (59.7% females) aged 12-60 years received COVID-19 vaccines via the national vaccination program. We collected the anthropometric data and fasting blood samples at specific time points before vaccination and after the final vaccination dose, and biochemical metabolic indices, including glucose and lipid profile, were measured. We also collected the dates of vaccination and COVID-19 history during the study period. The participants were stratified into groups based on first-to-second-dose intervals and time since the final dose to compare pre-and post-vaccination changes in metabolic indices between the groups. Logistic regression analysis revealed no differences in pre- to post-vaccination metabolic status between groups based on first-to-second-dose intervals in either adolescents or adults. However, shorter intervals (≤6 months) between the final dose and follow-up were associated with a decrease in total cardiometabolic components, especially triglyceride levels (OR = 0.39, 95% CI: (0.22-0.68), p < 0.001) than longer intervals (>6 months) in adults. In conclusion, time duration since final dose was associated with pre- to post-vaccination changes in metabolic indices, especially triglyceride levels, indicating that post-vaccination improvements wane over time. Further research is needed to validate the observed relationship, as it may contribute to optimizing vaccine effectiveness and safety in the future.

SARS-COV-2 MRNA vaccine-associated cutaneous vasculitis

During the coronavirus disease 2019 pandemic, global approach was to isolate populations with quarantine procedures to reduce the spread of this deadly virus until effective treatments are found or vaccines are developed. mRNA-based vaccines became available in the United States in March 2020. The Food and Drug Administration even issued an Emergency Use Authorization for individuals 16 years and older in December 2020. However, these rapid developments have brought along other problems such as possible side effects. As we develop and test a new treatment, it became clear how important side-effect management is. Here, we present a case of cutaneous vasculitis that developed on the fourth day of SARS-CoV-2 mRNA vaccination. The patient was successfully treated with medium-dose methylprednisolone.

Herpes Zoster and COVID-19 Vaccination: A Narrative Review

COVID-19 was a worldwide emergency, leading to a global health crisis, which completely revolutionized every aspect of human life. Several strategies were adopted to limit the spreading of the infection such as testing and contact tracing, quarantine and isolation, use of face mask, social distancing, lockdowns, travel restrictions, etc. Of these, vaccines were the most important measures to reduce the transmission of the virus and the severity of the infection, in order to overcome the pandemic. Fortunately, vaccination campaign was a success, showing to be efficient in controlling and preventing the COVID-19, reducing the risk of disease progression, hospitalization, and mortality. Monitoring and addressing vaccine-related adverse events have been essential for maintaining public confidence. Indeed, with the increasing number of vaccines administered, various cutaneous reactions have been reported, making dermatologists key players in their recognition and treatment. Particularly, several cutaneous diseases and cutaneous findings have been reported. Of note, also viral reactivations have been described following COVID-19 vaccination. Among these, varicella zoster virus (VZV) reactivation has been collected. Globally, an early diagnosis and an accurate treatment of herpes zoster (HZ) is mandatory to reduce possible complications. In this context, we conducted a review of the current literature investigating cases HZ following COVID-19 vaccination with the aim of understanding the possible causal correlation and underlying pathogenetic mechanisms to offer clinicians a wide perspective on VZV reactivation and COVID-19 vaccines.

Background rates for severe cutaneous reactions in the US: Contextual support for safety assessment of COVID-19 vaccines and novel biologics

The global COVID-19 public health crisis has resulted in extraordinary collaboration to expeditiously develop vaccines and therapeutics. The safety of these biologics is closely monitored by the US Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC). Novel products may have limited safety data, and although serious medical outcomes associated with vaccination are rare, knowledge of background incidence rates of medical conditions in the US population puts reported adverse events (AEs) in perspective for further study. Although relatively minor vaccination skin reactions are common, rare instances of severe delayed hypersensitivity reactions such as erythema multiforme (EM), Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and SJS/TEN overlap syndrome may occur. To aid in the assessment of these events, we performed a literature search in PubMed and Web of Science on the background incidence of EM, SJS, SJS/TEN, and TEN in the US population and on published reports of these conditions occurring post-vaccination. The US background annual incidence rates per million individuals of all ages ranged from 5.3 to 63.0 for SJS, from 0.4 to 5.0 for TEN, and from 0.8 to 1.6 for SJS/TEN. Since these conditions may overlap, some studies reported rates for EM/SJS/TEN combined, however we did not find studies with exclusive EM incidence rates. The published literature, including studies of reports submitted to the FDA/CDC Vaccine Adverse Event Reporting System (VAERS), describes post-vaccination EM, SJS, SJS/TEN and/or TEN as rare occurrences. The vaccines most frequently associated with these conditions were measles, mumps, and rubella; diphtheria, tetanus, and pertussis; and varicella. The majority of VAERS reports of EM, SJS, SJS/TEN, or TEN occurred in children within 30 days of vaccination. This review summarizes background rates of these disorders in the general population and published AEs among vaccine recipients, to support safety surveillance of COVID-19 vaccines and other biologics.

Cases of Pernio-Like Lesions after mRNA-1273 Vaccination with Clinical and Pathological Features: A Single-Center Experience

The currently available coronavirus disease 2019 (COVID-19) vaccines in South Korea include mRNA (Moderna® and Pfizer®) and adenoviral vector (AstraZeneca® and Janssen®) vaccines. Dermatologic side effects of COVID-19 vaccines range from local injection site reactions to systemic eruptions, including morbilliform rashes or erythema multiforme. Pernio-like lesions, one of the most common cutaneous manifestations of COVID-19, have been rarely reported post-vaccination. Herein, we report four cases of pernio-like lesions, which were detected in a single tertiary hospital within 2 months, after the first dose of mRNA-1273 (Moderna®) vaccination was administered. In this study, we discuss the clinical and pathological features of our cases and compare them with those of previously reported cases of pernio-like lesions after COVID-19 vaccination. It is pivotal to realize that perniolike lesions can be a possible side effect of COVID-19 vaccination and that the number of patients experiencing this side effect is bound to be quite high in real-world clinical settings.

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.

Pityriasis Rosea and Pityriasis Rosea-like Eruption Following COVID-19 Vaccinations: Case Series from Oman

To mitigate the impact of the COVID-19 pandemic, several vaccines have been developed and administered to the public since 2021. A spectrum of cutaneous reactions has been reported among some of the vaccinated individuals. In this case series, we describe three cases of pityriasis rosea and pityriasis rosea-like eruption that manifested after COVID-19 vaccinations, which might suggest the vaccines as a possible trigger.

A Study to Describe the Pattern of Cutaneous Adverse Effects of COVID-19 Vaccines (Covishield and Covaxin)

Background

Vigorous administration of COVID-19 vaccines to tackle the ongoing pandemic has led to increasing research on adverse effects including both systemic and cutaneous.

Objective

A prospective observational study to delineate the cutaneous adverse effects of two vaccines, namely Covishield and Covaxin, administered in two doses in northern India.

Materials and Methods

The study was conducted in a tertiary hospital in northern India wherein patients were asked to report voluntarily any cutaneous adverse effects after COVID-19 vaccination to the dermatology department. The data were collected using excel sheets and later analyzed taking into consideration the age, vaccine types, and duration of onset of adverse effects.

Results

Of the 19,672 vaccination jabs, 296 (1.5%) developed cutaneous adverse effects of which the incidence was higher in Covishield vaccine group compared to Covaxin vaccine group. The incidence of side effects was more with the first dose of either vaccine compared to the second dose. All the side effects were benign and were managed symptomatically or were self-limiting.

Limitations

The number of vaccine recipients was limited and there was a considerable overlap of adverse effects with both vaccines. Voluntary reporting of cases is not an accurate representation of the scale of patients with adverse effects.

Conclusion

Rampant administration of vaccines along with widespread advertisement of vaccine-induced side effects via social media has created apprehension in the general population. This warrants studies improving awareness about the most vital preventive measure available to halt and eventually end the COVID-19 pandemic.

New-onset chronic spontaneous urticaria post-COVID-19 vaccination-South African case series

Background

Chronic spontaneous urticaria (CSU) is defined as the spontaneous occurrence of hives, angioedema, or both for more than 6 weeks; several inciting triggers including vaccines have been implicated. Coronavirus disease 2019 (COVID-19) vaccinations have been well tolerated by patients with CSU. However, reports have emerged of CSU triggered by COVID-19 vaccination and this study describes a South African case series.

Objective

To provide details of the first case series of new-onset CSU post-COVID-19 vaccination in Africa and summarize the global literature of reported cases to date.

Methods

All patients referred to our Urticaria Center of Excellence in Cape Town from the initiation of the COVID-19 vaccine rollout in South Africa (from February 2021 to August 2022) were reviewed to identify patients who developed new-onset CSU within 12 weeks of receiving a COVID-19 vaccine. Medical history, physical examinations, and laboratory investigations were reviewed.

Results

More than 20 million adults received COVID-19 vaccinations in South Africa during the study period. Eight patients had new-onset chronic urticaria post-COVID-19 vaccination; 6 of the 8 patients were female, the median age was 41 years (interquartile range [IQR], 38-44), and all had a history of atopy. Only 1 reported COVID-19 infection post vaccination. Chronic urticaria occurred following Pfizer-BioNTech, AstraZeneca, and Janssen Ad26.COV2.S vaccination in 6, 1, and 1 patient, respectively, with a median of 12 days (IQR, 3-38) from vaccination to symptoms onset. The baseline median score for Urticarial Activity Score 7 was 34 (IQR, 29-40), and 5 of the 8 patients (63%) had a total IgE level of more than 43 IU/L. All patients received high-dose antihistamines, with only 3 patients controlled.

Conclusions

New-onset CSU can rarely be triggered by COVID-19 vaccinations, most commonly mRNA vaccines. COVID-19 vaccine-triggered CSU appears to have a phenotype similar to that triggered by other inciting agents and across populations.

An Update in COVID-19 Vaccine Reactions in 2023: Progress and Understanding

It has been 3 years since the coronavirus disease 2019 (COVID-19) pandemic was initially declared, and 2 years have passed since the first COVID-19 vaccines were introduced. Since then, 13.2 billion COVID-19 vaccine doses have been administered worldwide, largely with multiple doses of messenger RNA vaccines. Although mild local and systemic adverse effects after COVID-19 vaccination are common, serious adverse effects following immunization are rare, particularly when compared with the large number of vaccine doses administered. Immediate and delayed reactions are relatively common and present similarly to allergic and hypersensitivity reactions. Despite this, reactions generally do not commonly recur, cause sequelae, or contraindicate revaccination. In this Clinical Management Review, we provide an updated perspective of COVID-19 vaccine reactions, their spectrum and epidemiology, and recommended approaches to evaluation and management.

Clinical characteristics and immune profiles of patients with immune-mediated alopecia associated with COVID-19 vaccinations

BACKGROUND

The clinical characteristics and pathomechanism for immune-mediated alopecia following COVID-19 vaccinations are not clearly characterized.

OBJECTIVE

We investigated the causality and immune mechanism of COVID-19 vaccines-related alopecia areata (AA).

STUDY DESIGN

27 new-onset of AA patients after COVID-19 vaccinations and 106 vaccines-tolerant individuals were enrolled from multiple medical centers for analysis.

RESULTS

The antinuclear antibody, total IgE, granulysin, and PARC/CCL18 as well as peripheral eosinophil count were significantly elevated in the patients with COVID-19 vaccines-related AA compared with those in the tolerant individuals (P = 2.03 × 10-5-0.039). In vitro lymphocyte activation test revealed that granulysin, granzyme B, and IFN-γ released from the T cells of COVID-19 vaccines-related AA patients could be significantly increased by COVID-19 vaccine excipients (polyethylene glycol 2000 and polysorbate 80) or spike protein (P = 0.002-0.04).

CONCLUSIONS

Spike protein and excipients of COVID-19 vaccines could trigger T cell-mediated cytotoxicity, which contributes to the pathogenesis of immune-mediated alopecia associated with COVID-19 vaccines.
