Cutaneous Reactions to COVID-19 Vaccines: A Review

Effectiveness and safety of immune response to SARS‑CoV‑2 vaccine in patients with chronic kidney disease and dialysis: A systematic review and meta‑analysis

The coronavirus disease 2019 (COVID-19) vaccination is the most effective way to prevent COVID-19. However, for chronic kidney disease patients on long-term dialysis, there is a lack of evidence regarding the efficacy and safety of the immune response to the vaccine. The present meta-analysis explores the efficacy and safety of COVID-19 vaccine in the immune response of patients with chronic kidney disease (CKD) undergoing dialysis. PubMed, Web of Science, Science Direct, and Cochrane Library databases were systematically searched from January 1, 2020, to December 31, 2022. Data analysis was performed using REVMAN 5.1s and Stata14 software. Baseline data and endpoint events were extracted, mainly including age, sex, dialysis vintage, body mass index (BMI), vaccine type and dose, history of COVID-19 infection, seropositivity rate, antibody titer, pain at injection site, headache and other safety events. The meta-analysis included 33 trials involving 81,348 patients. The immune efficacy of patients with CKD and dialysis was 80% (95 CI, 73-87%). The seropositivity rate of individuals without COVID-19 infection was 76.48% (3,824/5,000), while the seropositivity rate of individuals with COVID-19 infection was 80.82% (1,858/2,299). The standard mean difference of antibody titers in CKD and dialysis patients with or without COVID-19 infection was 27.73 (95% CI, -19.58-75.04). A total of nine studies reported the most common adverse events: Pain at the injection site, accounting for 18% (95 CI, 6-29%), followed by fatigue and headache, accounting for 8 (95 CI, 4-13%) and 6% (95 CI, 2-9%), respectively. COVID-19 vaccine benefitted patients with CKD undergoing dialysis with seropositivity rate ≥80%. Adverse events such as fatigue, headache, and pain at the injection site may occur after COVID-19 vaccination but the incidence is low.

Clinicopathological characteristics of cutaneous complications following COVID-19 vaccination: A case series

INTRODUCTION

Several vaccine-related cutaneous adverse events occurred following the widespread use of vaccines to prevent coronavirus disease 2019 (COVID-19). This case series reports 25 patients with de novo or accentuated dermatologic conditions after receiving the Sinopharm, Sputnik V, AstraZeneca, or BIV1-CovIran vaccine in Iran.

METHODS AND RESULTS

Twenty-five eligible patients with a mean age of 46.80 years were investigated. The cutaneous adverse events included pityriasis rosea, zoster, viral exanthema, urticaria, bullous pemphigoid, pemphigus vulgaris, and acute generalized exanthematous pustulosis. The manifestations appeared 14.45 ± 6.98 and 20.79 ± 22.18 days following injection of the first and second doses of COVID-19 vaccines, respectively. All patients experienced new cases of cutaneous disease other than two who developed flare-ups of lichen planus and psoriasis.

CONCLUSION

Several cutaneous reactions, ranging from allergic events to skin diseases, have been reported following the injection of COVID-19 vaccines. Focal injection-site reactions are the most common cutaneous adverse events; however, de-novo skin diseases and a flare-up of preexisting cutaneous disorders have also been described. Although many cases of COVID-19 vaccine-related cutaneous diseases have been published, our zoster/lichen planus and AGEP cases after vaccination are interesting. A more detailed understanding of cutaneous adverse events following COVID-19 vaccination will facilitate better diagnosis and management.

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.

Dermatological manifestations associated with COVID-19 and COVID-19 vaccination: results from the Lebanese COVID registry

BACKGROUND

A number of cutaneous manifestations and adverse cutaneous reactions have been associated with COVID-19 infection and vaccine.

OBJECTIVES

A Lebanese national registry was established to characterize the dermatologic manifestations and adverse cutaneous reactions associated with COVID-19 infection and vaccination in a sample of the Lebanese population.

METHODS

An observational cross-sectional study was conducted via a web-based clinical form distributed to physicians wishing to report their cases from May 2021 till May 2022.

RESULTS

In total, 142 patients were entered in the registry, of which 133 were adults and nine were pediatric patients. The main dermatological manifestations reported with COVID-19 infection in the adult group were urticaria (32.9%), telogen effluvium (21.4%), morbilliform (10%), and papulosquamous (8.6%) eruptions. Urticaria was the most common adverse cutaneous reaction to the vaccine (33%). Interestingly, herpes zoster was triggered in 12 patients post vaccination in our series with this finding more frequently seen in patients above the age of 41 (P = 0.013). In the pediatric group, the most reported dermatological findings associated with COVID-19 infection were malar erythema (25%) and telogen effluvium (25%). One 16-year-old patient developed lichen planus after one dose of a COVID-19 vaccine. No deaths were reported in both age groups.

CONCLUSION

This Lebanese registry adds more robust evidence that clinical manifestations of the COVID-19 virus and vaccine are diverse. More studies are necessary to establish the pathophysiology of these dermatological findings in the context of COVID-19 infection and vaccination.

Exacerbation of Chronic Spontaneous Urticaria Following Coronavirus Disease 2019 (COVID-19) Vaccination in Omalizumab-Treated Patients

BACKGROUND

The rapid development and rollout of vaccines against coronavirus disease 2019 (COVID-19) has led to more than half of the world's population being vaccinated to date. Real-world data have reported various adverse cutaneous reactions, including delayed-onset urticaria, which was highly ranked as a common manifestation across studies. However, the impact of these novel mRNA or viral vector COVID-19 vaccines on preexisting chronic spontaneous urticaria (CSU) remains largely unknown.

OBJECTIVE

To investigate the impact of COVID-19 vaccination on the clinical status of patients with relatively stable CSU who are undergoing omalizumab treatment and to identify risk factors for exacerbation.

METHODS

We conducted a questionnaire-based cross-sectional study in a tertiary hospital. Adult patients with relatively stable CSU under regular omalizumab treatments who had received at least one COVID-19 vaccination were included.

RESULTS

There were 105 study subjects who received 230 COVID-19 vaccinations between March and December 2021. Fifteen patients (14.3%) experienced aggravation of urticaria at least once after COVID-19 vaccination. The demographics and clinical characteristics of the patients were comparable regardless of the exacerbation of CSU. However, case-level analysis revealed that the presence of urticaria (vs none) before vaccination (odds ratio [OR] = 4.99; 95% CI, 1.57-15.82) and the development of systemic reactogenicity (OR = 4.57; 95% CI, 1.62-12.90) were associated with a higher risk for exacerbation.

CONCLUSIONS

The novel COVID-19 vaccination induced exacerbation in more than one-tenth of patients with well-controlled CSU. The establishment of a proper management strategy during COVID-19 vaccination is necessary for patients with CSU.

Occurrence of erythema multiforme following COVID-19 vaccination: a review

The fast development of vaccines against the novel coronavirus disease is among the most critical steps taken to control this potentially fatal viral disease. Like other vaccines, the coronavirus disease 2019 (COVID-19) vaccines can also cause unwanted reactions. Erythema multiforme (EM) is among the oral mucocutaneous side effects of COVID-19 vaccines. This study aimed to comprehensively review the reported cases of EM since the global onset of COVID-19 vaccination. Data from 31 relevant studies regarding the type and dose of COVID-19 vaccines administered, time of initiation of symptoms, age, and gender of patients, site of involvement, patients' medical history, and treatment options were extracted. In total, 90 patients were identified with EM as a side effect of COVID-19 vaccination across studies. EM had the highest frequency after receiving the first dose of mRNA vaccines in older individuals. The first symptoms of EM appeared in less than 3 days in 45% and after 3 days in 55% of patients. EM is not a common side effect of COVID-19 vaccination, and fear of its occurrence should not impede vaccination.

Cutaneous reactions following COVID-19 vaccination assessed by dermatologists: a single-institutional study in Germany

BACKGROUND AND OBJECTIVES

Cutaneous reactions following COVID-19 vaccination have been frequently described, whereas larger case series by dermatologists are lacking. This study assesses SARS-CoV-2 vaccination-associated skin reactions, severity, treatment, course, eliciting vaccines, allergy test results and tolerance to revaccination.

PATIENTS AND METHODS

Single-institutional, non-interventional study of dermatologists assessing cutaneous manifestations in 83 patients in Germany.

RESULTS

93 reactions were presented. Manifestations clustered into immediate (n = 51, 54.8%) and delayed hypersensitivity reactions (n = 10, 10.8%), chronic inflammatory skin diseases (n = 13, 14.0%), reactivation of latent herpes virus infection (pityriasis rosea/herpes zoster; n = 9; 9.7%) and others (n = 10, 10.8%). Vaccination was associated with new (76.3%) - mostly hypersensitivity reactions - or exacerbation of known skin diseases (23.7%), in this case predominantly chronic inflammatory skin diseases. Reactions occurred primarily within the first week (72.8%) and after first vaccination (62.0%). Treatment was required in 83.9% and hospitalization in 19.4%. In 48.8% revaccination led to recurrence of the same reactions. Disease was ongoing at last consultation in 22.6%, primarily in chronic inflammatory skin diseases. Allergy tests were performed in 15 patients (18.1%) and resulted negative.

CONCLUSIONS

It can be assumed that vaccination may trigger immune activation-related reactions especially in those patients predisposed to develop respective skin diseases.

Pityriasis Rubra Pilaris After Moderna COVID-19 Vaccination: A Case Report and Literature Review

ABSTRACT

To date, over 60% of the world's population has received at least 1 dose of coronavirus disease 2019 (COVID-19) vaccination, with over 12 billion doses administered globally. Commonly reported adverse effects of COVID-19 vaccination include fever, headache, myalgia, and injection site reactions. The spectrum of documented cutaneous reactions after COVID-19 vaccination is broad; however, pityriasis rubra pilaris (PRP) or PRP-like eruption secondary to COVID-19 vaccine is exceedingly rare, with only 17 cases previously reported to date in the English literature. In this article, we describe an additional case of COVID-19 vaccination-associated PRP in a 50-year-old woman with a history of metastatic breast carcinoma, who developed a widespread cutaneous eruption characteristic of PRP, including palmoplantar keratoderma, 10 days after her third dose of Moderna COVID-19 vaccine. Punch biopsy specimen showed epidermal hyperplasia with overlying hyperkeratosis, alternating orthokeratosis and parakeratosis and focal follicular plugging, supporting the diagnosis of PRP. The patient improved within weeks of initiating oral acitretin and topical steroids, with resolution achieved after 3 months of continued therapy. To the best of our knowledge, this is the third reported case of Moderna COVID-19 vaccination-associated PRP and collectively the 18 th after the administration of all COVID-19 vaccines currently available, including Pfizer-BioNTech, and AstraZeneca.

COVID-19 Vaccination Status and Capsular Contracture Following Prosthetic Breast Reconstruction: A Retrospective, Multicenter Nested Case-Control Study

BACKGROUND

Capsular contracture (CC) is a common long-term complication following prosthetic-based breast reconstruction (PBBR). Seven cases of CC following mRNA vaccination for coronavirus 2019 (COVID-19) are reported in the literature.

OBJECTIVES

The aim of this study was to determine whether receiving the COVID-19 vaccine was associated with CC development following PBBR.

METHODS

A retrospective, multicenter nested case-control study was performed from January 2014 to July 2022 of adult female patients who underwent PBBR with acellular dermal matrix placement. Cases of CC were selected if no adjuvant radiation was received and they presented for follow-up between December 2020 and July 2022. Controls included patients who met inclusion criteria but who did not experience CC in either breast. Patient demographics, breast cancer characteristics, reconstructive surgery details, postoperative complications, and COVID-19 exposure details were analyzed and correlated with CC development.

RESULTS

Of a total of 230 patients (393 breasts) who received PBBR, 85 patients (135 breasts) met inclusion criteria, of whom 12 patients (19 breasts) developed CC and 73 patients (116 breasts) did not. At the time of median follow-up of 18.1 months (n = 85; interquartile range, 12.2-33.6 months), no statistically significant differences were observed between the short- or long-term complications in cases or controls. There were no significant differences in COVID-19 vaccination status, number of vaccine doses, or vaccination type between cases and controls. Vaccination status was not associated with greater odds of CC development (odds ratio, 1.44; 95% CI, 0.42-5.37; P > .05).

CONCLUSIONS

Direct association between CC and COVID-19 vaccination is difficult to prove. Given the known risk of severe COVID-19 infection among immunocompromised patients, those with breast cancer who undergo PBBR should be properly counseled on the benefits and risks of vaccination.

Global incidence pattern and factors associated with common cutaneous reactions related to COVID-19 vaccination of 2.55 million participants in real-world settings: A systematic review and meta-analysis

Background

Understanding the incidence pattern of cutaneous reactions is crucial for promoting COVID-19 vaccination. We aimed to report the global incidence pattern of, and factors associated with common cutaneous reactions related to COVID-19 vaccination in real-world settings.

Methods

We searched five databases (PubMed, Web of Science, Embase, CNKI, and Wanfang) from inception to May 13, 2022, for studies reporting the incidence of common cutaneous reactions related to COVID-19 vaccines in real-world settings. The outcomes were the systematic skin reactions (rash and urticaria) and the local injection site reactions (pain, swelling, redness, and erythema). We conducted random-effects meta-analyses and explored associated factors using multi-step statistical analyses.

Results

We included 35 studies and assessed 2 549 968 participants from 23 countries. The pooled incidence of overall systemic skin reactions was 3.8% (95% confidence interval (CI) = 2.4%-5.5%) with short duration (about one week). Specifically, the pooled incidence rates of rash and urticaria were 3.0% (95% CI = 2.1%-3.9%) and 1.1% (95% CI = 0.7%-1.5%), respectively. For overall local injection site reactions, the pooled incidence was 72.4% (95% CI = 65.7%-78.7%) with short duration (1 to 4.5 days). Except for local pain (72.2%, 95% CI = 65.3%-78.5%), other localized reactions had low incidence, including swelling (13.3%, 95% CI = 9.5%-17.7%), redness (11.5%, 95% CI = 5.7%-19.0%), and erythema (5.8%, 95% CI = 0.7%-15.4%). Geographically, different distribution patterns were observed for these reactions. Regarding associated factors, mRNA vaccines showed lower incidence of urticaria (P < 0.001). Asia population showed higher incidence of urticaria (P < 0.001). We observed lower incidence rates of overall local injection site reactions and pain among inactivated vaccines (P < 0.001). We found no significant difference among reactions between the first and the second dose of vaccines.

Conclusions

We examined the global incidence pattern of common cutaneous reactions related to COVID-19 vaccination and found low incidence and short duration of systemic skin reactions and local injection site reactions (except for pain); discrepancies in these reactions were observed across different vaccine types. The cutaneous side effects related to COVID-19 vaccination do not seem to cause concern.
