Toxic Epidermal Necrolysis Post COVID-19 Vaccination - First Reported Case

Effects of post-COVID-19 vaccination in oral cavity: a systematic review

OBJECTIVES

SARS-CoV-2 virus and its variants continue to be on a rampage worldwide. Several vaccines are being marketed to control their spread and reduce severity of symptoms in the affected. Various adverse events are being reported following the vaccine administration and therefore this systematic review investigated the oral adverse events post-COVID-19 vaccination.

MATERIALS AND METHODS

A systematic search of five databases was conducted. Case reports, case series and observational studies describing oral lesions/oral adverse effects (outcome) following anti-SARS-CoV-2 vaccination (exposure) in humans were included. Quality assessment of the studies was done using Joanna Briggs Institute Critical Appraisal tools. A working classification was developed from reported final diagnosis.

RESULTS

The systematic review included 18 individual cases. Majority of oral lesions occurred following BNT162b2 vaccination with average age of occurrence at 59.94 years. 67% of the affected individuals were female, with hypertension being the most common comorbidity.

DISCUSSION

Immune-mediated oral events have a propensity of occurrence following COVID-19 vaccination. mRNA-based vaccinations may have an affinity for causing oral adverse effects. It might be due to the immune dysregulation caused by these vaccinations.

CONCLUSION

The female, geriatric population and older individuals with co-morbidities might have an increased affinity to develop oral lesions post-COVID-19 vaccination.

Management of coronavirus disease 2019 vaccine-induced cutaneous complications: A comprehensive literature review

Despite the numerous reports of cutaneous manifestations associated with vaccines for coronavirus disease 2019 (COVID-19), the relationship between COVID-19 vaccines and cutaneous side effects remains unevaluated. In this review, we examine these manifestations and their management. Reported dermatoses included injection-site reaction (early and delayed), type I allergic reaction, morbilliform eruption, pityriasis rosea, Sweet syndrome, lichen planus, psoriasis, herpes zoster reactivation, erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis (TEN). The most common COVID-19 vaccination-related cutaneous manifestations are delayed local reactions, approximately 66% of which are associated with the Moderna vaccine, and 33% with the Pfizer vaccine. Aside from mild injection-site reactions, severe reactions include anaphylaxis and TEN. Most reactions, except for Stevens-Johnson syndrome and anaphylaxis, though unpredictable and unpreventable are mild and can be treated symptomatically. Findings from this review should allow primary care physicians and dermatologists to reach faster diagnosis and initiate prompt intervention.

Biologic TNF-α Inhibitors for Stevens-Johnson Syndrome, Toxic Epidermal Necrolysis, and TEN-SJS Overlap: A Study-Level and Patient-Level Meta-Analysis

INTRODUCTION

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe cutaneous adverse reactions with high morbidity and mortality and not clearly established treatment protocol. This meta-analysis aimed to evaluate the efficacy and safety of three biologic TNF-α inhibitors (infliximab, etanercept, adalimumab) in the treatment of SJS, SJS-TEN overlap, and TEN.

METHODS

Electronic databases were searched for original studies containing human participants diagnosed with SJS/TEN and treated with biologic TNF-α inhibitors. Individual patient data were collected and summarized to provide a comprehensive overview on therapeutic efficacy of different biologic TNF-α inhibitors for SJS, SJS-TEN overlap, and TEN, respectively. Meta-analyses on aggregated study data were conducted using random-effects model.

RESULTS

Overall, 55 studies with 125 sets of individual patient data were included. Infliximab was used to treat 3 patients with SJS-TEN overlap and 28 patients with TEN, and the actual mortality rate was 33.3% and 17%, respectively. Etanercept was administered to 17 patients with SJS, 9 patients with SJS-TEN overlap, and 64 patients with TEN, and mortality rate was reported to be 0%, 0%, and 12.5%, respectively. For participants with TEN, no significant difference was found in time of reepithelialization, hospitalization time, and mortality rate comparing etanercept with infliximab. More sequelae were reported in patients receiving infliximab than in patients treated with etanercept (39.3% versus 6.4%). Adalimumab was administered to four patients with TEN, and mortality rate was 25%. Meta-analyses on aggregated study data revealed significantly shortened hospitalization time in etanercept compared with non-etanercept groups [weighted mean differences (WMD) -5.30; 95% confidence interval (CI) -8.65 to -1.96]. Etanercept was associated with a survival benefit for patients when compared with non-etanercept treatment, however, the analysis was not statistically significant (odds ratio 0.55; 95% CI 0.23-1.33).

CONCLUSIONS

On the basis of the current findings, etanercept is currently the most promising biologic therapy for SJS/TEN. Further evaluation in prospective studies is required to confirm its efficacy and safety.

Various aspects of the relationship between vitiligo and the COVID-19 pandemic or SARS-CoV-2 vaccines: Clinical pearls for dermatologists

BACKGROUND

Coronavirus disease 2019 (COVID-19) has given rise to several new onset or exacerbated dermatologic disorders including vitiligo.

AIM AND METHOD

Here, we present different aspects of relationship between SARS-CoV-2 infection or its associated vaccines and vitiligo and aim to provide solutions to overcome the potential challenges.

RESULTS AND CONCLUSION

In brief, as the benefits overweigh the risks and since vaccine-triggered de novo or flares of vitiligo are uncommon and benign, these patients are recommended to get SARS-CoV-2 vaccines. Moreover, in individuals with previously recognized vitiligo, who are at risk of developing SARS-CoV-2 infection or those who are currently infected, special dermatologic consultation is needed in order to balance the immunosuppressive agents in their therapeutic regimen to prevent COVID-related morbidity and mortality.

Toxic epidermal necrolysis and Stevens-Johnson syndrome after COVID-19 infection and vaccination

Stevens-Johnson Syndrome (SJS) is a rare but severe skin reaction characterized by blistering and peeling of the skin and ulcerations of mucous membranes; toxic epidermal necrolysis (TEN) is a subset of SJS characterized by the involvement of >30% of the skin. Though previously associated with drugs and infections, discussions on the association between TEN/SJS and COVID-19 have been limited. We present a review of TEN/SJS after COVID-19 infection and vaccination. Literature searches were conducted on PubMed and Google Scholar from 2019 to 8/2022. Thirty-eight articles were selected based on subject relevance, and references within selected articles were also screened for relevance. As of 8/2022, there have been 34 published cases of TEN, SJS, and SJS-TEN overlap after COVID-19 infection and vaccination, including 12 cases after vaccination and 22 cases after infection. Multiple authors hypothesize that virotopes or excipients in COVID-19 vaccines can activate T-cells or cytokines to induce TEN/SJS. Meanwhile, some hypothesize that COVID-19 infection induces immune activation that can trigger TEN/SJS or increase susceptibility to drug-induced TEN/SJS. Treatments for post-infection and post-vaccination TEN/SJS vary significantly. We recommend remaining vigilant for this rare and severe potential complication.

COVID-induced toxic epidermal necrolysis in a 4-year-old female: a case report and literature review

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are conditions characterized by an immune-mediated skin reaction that results in blistering and epidermal detachment. Most cases are caused by drug hypersensitivity; however, recently there have been many publications documenting the association between coronavirus disease 2019 (COVID-19) and SJS/TEN. Our objective is to explore a case of a 4-year-old female who presented with a papular rash on her thighs that progressively worsened and spread to her face, trunk, and genital area. The patient tested positive for COVID-19. She required treatment with intravenous immunoglobulin (IVIG) and IV methylprednisolone, but eventually made a full recovery. This case underscores the need for awareness of the wide spectrum of dermatologic presentations in COVID-19 patients.

Toxic epidermal necrolysis in hepatitis A infection with acute-on-chronic liver failure: Case report and literature review

Toxic epidermal necrolysis (TEN) and Stevens–Johnson syndrome (SJS) are acute inflammatory skin adverse reactions characterized by epidermal exfoliation and multi-site mucositis and are considered medical emergencies. The risk factors for SJS/TEN include immune disorders, malignancy, and genetic susceptibility. In most cases, medication is considered to be the leading cause of TEN. In addition, several studies suggest that infections, such as the herpes simplex virus, human immunodeficiency virus (HIV), Mycoplasma pneumoniae, streptococcus, and meningococcus infections, can trigger the occurrence of SJS/TEN. In this rare case, we share our experience managing TEN in a hepatitis A virus infection with an acute-on-chronic liver failure patient. A 38-year-old man was infected with hepatitis A virus on the basis of liver cirrhosis and progressed to acute-on-chronic liver failure. As the infection progressed, the target-like skin lesions accompanied by mucosal involvement worsened. The condition of the patient progressively worsened with a severe generalized rash, bullae, and epidermal detachment accompanied by severe erosive mucosal lesions. His skin detachment area gradually involved 30% of the body surface area (BSA), and the disease progressed to TEN. The intravenous infusion of corticosteroids alleviated the patient's hypersensitivity, and the patient obtained lasting remission without severe adverse reactions and complications.

Stevens-Johnson syndrome and toxic epidermal necrolysis: A systematic review of PubMed/MEDLINE case reports from 1980 to 2020

Background

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare, life-threatening immunologic reactions. Prior studies using electronic health records, registries or reporting databases are often limited in sample size or lack clinical details. We reviewed diverse detailed case reports published over four decades.

Methods

Stevens-Johnson syndrome and toxic epidermal necrolysis-related case reports were identified from the MEDLINE database between 1980 and 2020. Each report was classified by severity (i.e., SJS, TEN, or SJS-TEN overlap) after being considered a “probable” or “definite” SJS/TEN case. The demographics, preconditions, culprit agents, clinical course, and mortality of the cases were analyzed across the disease severity.

Results

Among 1,059 “probable” or “definite” cases, there were 381 (36.0%) SJS, 602 (56.8%) TEN, and 76 (7.2%) SJS-TEN overlap cases, with a mortality rate of 6.3%, 24.4%, and 21.1%, respectively. Over one-third of cases had immunocompromised conditions preceding onset, including cancer (n = 194,18.3%), autoimmune diseases (n = 97, 9.2%), and human immunodeficiency virus (HIV) (n = 52, 4.9%). During the acute phase of the reaction, 843 (79.5%) cases reported mucous membrane involvement and 210 (19.8%) involved visceral organs. Most cases were drug-induced (n = 957, 90.3%). A total of 379 drug culprits were reported; the most frequently reported drug were antibiotics (n = 285, 26.9%), followed by anticonvulsants (n = 196, 18.5%), analgesics/anesthetics (n = 126, 11.9%), and antineoplastics (n = 120, 11.3%). 127 (12.0%) cases reported non-drug culprits, including infections (n = 68, 6.4%), of which 44 were associated with a mycoplasma pneumoniae infection and radiotherapy (n = 27, 2.5%).

Conclusion

An expansive list of potential causative agents were identified from a large set of literature-reported SJS/TEN cases, which warrant future investigation to understand risk factors and clinical manifestations of SJS/TEN in different populations.

Cutaneous manifestations following COVID-19 vaccination: A report of 25 cases

Various adverse effects particularly cutaneous manifestations associated with different COVID-19 vaccines have been observed in practice. The aim of our study was to evaluate all patients who presented to our tertiary center with skin manifestations following COVID-19 vaccines injection from September to December 2021. All patients with skin manifestation within 30 days or less following COVID-19 vaccination were enrolled in our case-series. All cases included in our study were diagnosed based on clinical and/or histopathological evaluation and all other possible differential diagnoses were ruled out. Twenty-five individuals including 16 (64%) males and 9 (36%) females with the mean age of 47 ± 17.62 years (range 18-91) were enrolled in our study. Twenty-two (88%) patients developed lesions after Sinopharm vaccine injection and 3 (12%) cases manifested lesions after the AstraZeneca vaccine. Six (24%) patients developed new-onset lichen planus (LP) and 1 (4%) patient manifested LP flare-up. Two (8%) individuals developed psoriasis and 1 (4%) case showed psoriasis exacerbation. One (4%) patient developed new-onset pemphigus vulgaris (PV) and 1 (4%) case experienced a flare of PV lesions. One (4%) patient manifested pityriasis lichenoides et varioliformis acuta (PLEVA) flare-up. Other new-onset cases were as follows: toxic epidermal necrolysis (TEN) (n = 1, 4%), bullous pemphigoid (BP) (n = 2, 8%), alopecia areata (AA) (n = 2, 8%), pytriasis rosea (n = 1, 4%), herpes zoster (n = 1, 4%), cutaneous small vessel vasculitis (n = 1, 4%), erythema multiform (EM) and urticaria (n = 3, 12%), and morphea (n = 1, 4%). Physicians should be aware of the possible side effects especially cutaneous manifestations associated with COVID-19 vaccines.

What to expect when AGEP is induced by terbinafine? case report and critical review of the literature

BACKGROUND

Acute Generalized Exanthematous Pustulosis (AGEP) is a rash with multiple sterile intraepidermal or sub corneal non-follicular pustules on edematous papules, with a sudden development and rapid evolution, triggered by drugs, vaccination, insect bites, exposure to mercury and allergens.

OBJECTIVES AND METHODS

We describe a female patient who developed extensive and abnormally prolonged AGEP following exposure to terbinafine and Sars-COV Vaccine. A detailed review of terbinafine-induced-AGEP cases was performed, with the aim of evaluating if the AGEP criteria would follow a different pattern when the disease is triggered by this drug. A pubmed search helped retrieve all terbinafine induced AGEP case reports. AGEP specific Sideroff criteria were analyzed in Terbinafine-induced cases, and compared to other trigger causes.

CONCLUSIONS

when AGEP causative drug was terbinafine, a delay in recovery was observed, compared to the existing AGEP criteria when other causes are considered. Terbinafine frequently leads to delayed resolution AGEP probably due to the presence of the drug in the skin during several weeks after exposure, even after discontinuation, and the disease severity may be potentialized by additional factors such as concomitant viral infections or vaccination.

Cutaneous Complications of mRNA and AZD1222 COVID-19 Vaccines: A Worldwide Review

Because of the increasing emergence of cutaneous reactions from COVID-19 vaccines worldwide, we investigated the published reports of these complications. We searched the PubMed, Google Scholar, and Scopus databases and the preprint server bioRxiv for articles on cutaneous complications linked to mRNA-1273 (Moderna), BNT162b2 (Pfizer–BioNTech), and AZD1222 (AstraZeneca–Oxford University) vaccines published until 30 September 2021. Eighty studies describing a total of 1415 reactions were included. Cutaneous reactions were more prevalent in females (81.6%). Delayed large local reactions were the most common complication (40.4%), followed by local injection site reactions (16.5%), zoster (9.5%), and urticarial eruptions (9.0%). Injection site and delayed large local reactions were predominantly caused by the mRNA-1273 vaccine (79.5% and 72.0%, respectively). BNT162b2 vaccination was more closely linked to distant reactions (50.1%) than mRNA-1273 (30.0%). Zoster was the most common distant reaction. Of reactions with adequate information for both vaccine doses, 58.3% occurred after the first dose only, 26.9% after the second dose only, and 14.8% after both doses. Overall, a large spectrum of cutaneous reaction patterns occurred following the COVID-19 vaccination. Most were mild and without long-term health implications. Therefore, the occurrence of such dermatologic complications does not contraindicate subsequent vaccination.

A Life-Threatening Case of Torsemide-Induced Toxic Epidermal Necrolysis Associated With the Treatment of Anasarca

Toxic Epidermal Necrolysis (TEN), along with Stevens-Johnson Syndrome (SJS), are rare, life-threatening delayed type IV hypersensitivity mucocutaneous skin disorders that can often be precipitated by medications. The most common culprits are sulfonamide antibiotics and various antiseizure medications. We report a case of a 41-year-old Black female that initially presented with SJS, which then rapidly progressed to TEN, confirmed by hematoxylin and eosin stain skin biopsies. Approximately 80% of her body surface area had necrosis and epidermal detachment lesions. It was concluded that TEN was caused by the use of torsemide for treatment of her underlying diffuse anasarca attributable to alcoholic cirrhosis. During her one-month hospital stay, a multi-disciplinary team consisting of dermatology, gynecology, rheumatology, nephrology, and infectious disease evaluated and treated the patient. Interventions included various supportive care measures as well as intravenous steroids, cyclosporine, plasma exchange, and intravenous immunoglobulin. Given that the mortality rate for TEN is over 30%, and this patient had end-stage cirrhosis, her prognosis was extremely poor. Even though her TEN eventually healed slowly, the patient experienced complications. This case demonstrates the importance of cautiously using sulfonamide medications in patients with known hypersensitivity to sulfa drugs.

Cutaneous Adverse Reactions Associated with SARS-CoV-2 Vaccines

Many patients are receiving SARS-CoV-2 vaccinations, which have been associated with a variety of adverse effects. Cutaneous adverse reactions to SARS-CoV-2 vaccinations have been progressively reported, but they have not been reviewed according to their morphological clinical patterns. The objective of this review was to summarize the existing data concerning the cutaneous adverse reactions following SARS-CoV-2 vaccines and group them according to common morphological and pathogenetic patterns. We reviewed the English language literature up to 15 August 2021, using predefined keywords to identify the relevant studies evaluating cutaneous adverse reactions associated with SARS-CoV-2 vaccines. We search for recurrent morphological patterns sharing clinical signs and symptoms and physio-pathological mechanisms. Timing to onset following the first or booster dose of the vaccine, predisposing conditions, therapeutic management, and outcome were also collected. Among the dermatological manifestations associated with SARS-CoV-2 vaccinations, we distinguished: (1) new onset reactions and (2) flares of preexisting dermatoses. The most common were injection site reactions, affecting 30–70% and generally mild or moderate. Small case series or single case reports included filler reactions, exanthemas, vascular lesions, urticaria, eczematous dermatitis, autoimmune bullous reactions, and severe cutaneous adverse reactions. In addition, the exacerbation of chronic immuno-mediated dermatoses (mainly psoriasis and atopic dermatitis) and reactivations of herpes infection were reported. The cutaneous reactions were generally mild, self-limiting, and resembled common cutaneous drug eruptions and/or COVID-19 skin manifestations.

Stevens-Johnson Syndrome due to COVID-19 vaccination

As public COVID-19 vaccination programs are being implemented, it is possible that more rare and serious adverse effects such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrosis (TEN) may occur.
