COVID-19 vaccines and filler reactions: Should it be considered as a concern?

BACKGROUND: Any implant or external material used in the body tissues can potentially be followed by autoimmune or inflammatory reactions. With the global vaccination program against COVID-19, the reports of tissue filler reactions would be increasingly demonstrated. AIM: To summarize the data regarding COVID vaccination and filler reactions. METHOD: We reviewed the existing data in this regard through searching on PubMed, Google Scholar and Scopus. All of the relevant papers published until March 2022, which we could access to their fulltexts were included. RESULTS: Here, we summarized the data regarding COVID-19 vaccination and filler reactions and discussed its etiopathogenesis, management, and importance. CONCLUSION: Although the end of pandemic was announced, the necessity of continuing COVI-D19 vaccination in future mandates gathering data regarding safety of vaccines.

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.

COVID‐19 vaccination in children as a global dilemma through an ethical lens: A retrospective review

Background and Aims COVID‐19 pandemic led to a need to rapidly vaccinate as many people as possible. Children are an important part of the population with different characteristics which vaccinating them is a matter of great importance as it should be decided considering all aspects and ethics. Here, we present different aspects of COVID vaccination in children including the potential challenges. Methods We searched on PubMed, Google Scholar and Scopus in this regard, and all of the relevant papers published until June 28, 2021 were included if we could access their full‐texts. Results We found various expert opinions in this regard and tried to summarized them. Saving lives has similar ethical value as preventing evitable adverse event. Accordingly, mandating the children to receive the SARS‐CoV‐2 vaccine, needs risk‐benefit weighing with special consideration of ethical challenges. Conclusion Considering the vast range of benefits resulted from pediatric vaccination both for the children and the community, implementing the program in a scientific manner and also with the least financial expenses for the families seems to be reasonable and makes it both ethical and moral.

Unmasking sarcoidosis following SARS-CoV-2 vaccination: A case report.

Sarcoidosis is an inflammatory and granulomatous disorder, developed due to dysregulation between immune response and certain environmental antigens. We hereby report an interesting case of sarcoidosis following COVID-19 vaccination (COVIran Barekat), which presented with inflammation of previous tattoo sites as well as the development of erythema nodosum and systemic lymphadenopathy, suggested a possible link between the COVID vaccination and dysregulation of the inflammatory process and served as a reminder for clinicians to have enough vigilance before proposing a vaccine booster to these patients.

COVID vaccine recommendations in dermatologic patients on immunosuppressive agents: Lessons learned from pandemic.

Since SARS-CoV2 vaccines were approved without enough long-term monitoring due to emergent situations, some issues have been raised about timing and protocol of receiving them by patients treated by different immunosuppressive agents. Here, we present different aspects of SARS-CoV-2 vaccination in such patients in the field of dermatology. In brief, SARS-CoV-2 vaccination is recommended in all dermatologic patients, regardless of their disorders and therapeutic regimens. Nevertheless, special considerations should be given to the immunosuppressive therapy and its association with vaccination timing due to the decreased immunogenicity of vaccines in this setting. Novel biologic immunotherapies are advantageous over conventional systemic therapies not only in their safety and selective functions but also in this aspect that many of them do not affect vaccines immunogenicity.

Coexistence of Pemphigus Vulgaris and Lichen Planus following COVID-19 Vaccination.

SARS-CoV-2 vaccines were approved without long-term monitoring due to emergent situation and might have several side effects. Herein, we describe the first case with development of both LP and PV following COVID-19 vaccination. Immunological alteration due to COVID-19 vaccination and its potential role in triggering autoimmune disorders were also dealt with.

Acute Generalized Exanthematous Pustulosis following SARS-CoV-2 Virus: Remdesivir as a Suspected Culprit.

Acute generalized exanthematous pustulosis (AGEP) is an exanthematous condition, predominantly occurring as a result of drug reactions. We, hereby, present the first case of AGEP following treatment with remdesivir in a patient with COVID-19, without hydroxychloroquine use, which serves as a reminder to consider remdesivir as a possible causative agent when dealing with AGEP presentation in COVID patients.

New-onset pemphigus foliaceus following SARS-CoV-2 infection and unmasking multiple sclerosis: A case report.

Development of pemphigus foliaceus (PF) following SARS-CoV-2 infection has only been reported in one patient who had received Bamlanivimab and thus might be considered as a drug-induced case of PF. Here, we reported the first case of PF arising solely after COVID infection without taking any culprit drug.

A systematic review on COVID-19 vaccination and cosmetic filler reactions: A focus on case studies and original articles.

BACKGROUND: Tissue fillers are among the most popular cosmetic procedures performed and notably, cases of filler reactions after COVID-19 vaccination have been reported. OBJECTIVE: The objective was to determine the characteristics of patients with filler reaction after COVID-19 vaccination and address several considerations that have to be taken into practice. METHODS: A PRISMA compliant systematic search was conducted in Scopus, Web of Science, and PubMed/MEDLINE databases for articles published from inception up to October 21, 2021. RESULTS: Out of 106 initially retrieved articles, four of them were included in our study, and a total number of 13 cases were analyzed. In this study, we found that all of the patients who developed delayed-type reaction (DTR) following COVID-19 vaccination were middle-aged women without any known history of allergy to foods or drugs. All patients had a history of hyaluronic acid (HA) filler injection in their head and neck and demonstrated symptoms particularly swelling, from <1 day up to 10 days after the first or second doses of vaccines. Lisinopril, hyaluronidase, and corticosteroids seemed to have good results in management. CONCLUSION: Although rare, DTR to fillers after COVID-19 vaccination can happen. Physicians should be aware of the pathogenesis and management of this phenomenon.

Morphea in two patients after being infected to and being vaccinated against SARS‐CoV‐2 infection

Although the presence of morphea following COVID‐19 has been rarely reported, the development of its generalized form following COVID‐19 vaccination has not been reported yet. Here, we reported the first case of generalized morphea following COVID‐19 vaccination and another similar case following SARS‐Cov‐2 infection. Other etiologic factors were also dealt with. COVID‐19, and recently the associated vaccines, have led to any dermatologic condition. Here, we reported the first case of generalized morphea following COVID‐19 vaccination and another similar case following SARS‐Cov‐2 infection.

The role of SARS-CoV-2 infection and its vaccines in various types of hair loss.

The prevalence of hair loss has increased during COVID-19. In this study, we review the current literature on incidence and characteristics of various types of COVID-19-related and COVID-19-vaccine- related hair loss including telogen effluvium, alopecia areata, friction alopecia and anagen effluvium. Regarding most of them, the more severe the infection, the more profound and prolonged the course of alopecia. However, the most important issue is reassuring the patients of the non-serious nature of this complication, since psychological support is the most important factor in the earlier resolution of the condition.

SARS-CoV-2 vaccination and practical points in psoriasis patients: A narrative review.

SARS-CoV2 vaccines were approved without long-term monitoring due to emergent situations. This has raised some issues about timing and protocol of receiving vaccines in specific situations including patients with chronic inflammatory disorders such as psoriasis. Here, we present different aspects of SARS-CoV-2 infection and vaccination in psoriasis patients and aim to provide solutions to overcome the potential challenges. In brief, the benefits of vaccination outweigh the potential risk; vaccine-triggered de novo or flares of psoriasis is uncommon. As such, all psoriasis patients, especially those receiving systemic treatments including anti tumor necrosis factor agents, are strongly recommended to get SARS-CoV-2 vaccines. It is recommended that new immunosuppressive/immunomodulatory therapies be initiated at least 1 week after the second SARS-CoV-2 vaccine dose, if possible. In addition, in severe and active forms of psoriasis, it is better to delay vaccination until stabilization of the disease.

Case of atypical disseminated herpes zoster in a patient with COVID‐19: A diagnostic challenge in COVID era

Herpes Zoster caused by reactivation of latent Varicella–Zoster virus (VZV). The rare disseminated form of it occurred mainly in immunocompromised patients. We hereby present the first case of atypical disseminated herpes zoster in a 54‐year‐old woman admitted with serious COVID. In this case, disseminated herpes zoster developed by purpuric lesions mimicking vasculitis and cutaneous drug reaction. Hence, this case serves as a reminder for considering atypical presentations of cutaneous disorders in immunocompromised patients, especially those affected with severe COVID. We presented the first case of atypical disseminated herpes zoster (HZ) in a case of serious COVID. The risk of dissemination and atypical presentation of HZ might be increased in serious COVID with long‐term hospitalization and/or ICU admission.

COVID vaccination in patients under treatment with rituximab: A presentation of two cases from Iran and a review of the current knowledge with a specific focus on pemphigus.

SARS-COV2 vaccines were approved without long-term monitoring due to emergent situations. This has raised some issues about the timing and protocol of receiving vaccines in specific situations such as patients receiving immunomodulatory agents including rituximab, which is widely used for various disorders such as multiple sclerosis, pemphigus, and many rheumatologic disorders. We described two cases of pemphigus vulgaris (a new case and one with flare-up) following vaccination with Astrazeneca in Iran and reviewed the existing data in this regard through searching on PubMed, Google Scholar, and Scopus. All of the relevant papers published until June 28, 2021, which we could access their full-texts were included. We found some recommendations made by rheumatologists, neurologists, and dermatologists in regard to vaccination timing in this group of patients and tried to summarize them to provide a practical guide for clinicians. Clinicians should perform a careful, individualized risk-benefit assessment for their patients and consider a delay in rituximab administration after completion of COVID vaccination if there is not any considerable risk of disease relapse or organ failure. Moreover, choosing vaccines with potential of providing protection after single dose, especially in countries with limited access to vaccines may be a reasonable approach.
