Case of immunoglobulin A vasculitis following coronavirus disease 2019 vaccination

Cutaneous adverse events following COVID-19 vaccination: A case series of 30 Japanese patients and a review of 93 Japanese studies

In Japan, cutaneous adverse events (AEs) following the coronavirus disease 2019 (COVID-19) vaccination have been frequently described; however, a larger case series and literature review are lacking. There is an urgent need for an extensive investigation of new cases and previous reports to provide a thorough body of information about post-COVID-19 immunization cutaneous AEs. We aimed to analyze patients with cutaneous AEs after COVID-19 vaccination in our hospital and review previous studies of cutaneous AEs. We analyzed post-COVID-19 vaccination cutaneous AEs in our department, the Japanese Registry, and previous literature. We enrolled 30 patients with cutaneous post-vaccination AEs in our department over 2 years (April 1, 2021, to March 31, 2023). We also confirmed cases registered in the Ministry of Health, Labor, and Welfare COVID-19 vaccine side effect reporting system (February 17, 2021-March 12, 2023). A total of 587 records were retrieved and 93 articles were included for data extraction. A total of 28 non-injection-site cutaneous AEs and two injection-site AEs were identified. Six (20.0%) patients developed new-onset erythematous eruptions, and five (16.7%) patients developed urticaria. Pruritic eruption, eczema, shingles, and sweating symptoms have also been reported. In previous studies on non-injection-site cutaneous AEs, individuals who received the BNT162b2 vaccine were older than those who received mRNA-1273 (P < 0.01). Cutaneous AEs were mostly nonsignificant and self-limiting reactions; however, rare, severe, or life-threatening AEs were also reported. Physicians should be aware of the various possible cutaneous AEs associated with the COVID-19 vaccination.

Henoch-schonlein purpura following exposure to SARS-CoV2 vaccine or infection: a systematic review and a case report

BACKGROUND

Henoch-Schonlein purpura (HSP) is an IgA-mediated systemic small-vessel vasculitis (IgAV) that typically presents with a variable tetrad of symptoms. HSP if often preceded by respiratory tract infections, vaccinations, drugs or malignancies. During the recent COVID-19 pandemic multiples cases of HSP have been described after both infection and vaccination for SARS-CoV2. This study aims to perform a systematic review of literature and describe an additional complicated case of de-novo HSP appeared after the administration of the third dose of a mRNA-SARS-CoV2 vaccination.

METHODS

Electronic bibliographic research was performed to identify all the original reports describing cases of de-novo HSP or IgAV appeared after respiratory infection or vaccine administration for SARS-CoV2. We included all case series or case reports of patients who respected our inclusion and exclusion criteria.

RESULTS

Thirty-eight publications met our pre-defined inclusion criteria, for an overall number of 44 patients. All patients presented with palpable purpura variable associated with arthralgia, abdominal pain or renal involvement. Increased levels of inflammation markers, mild leukocytosis and elevated D-dimer were the most common laboratory findings. Up to 50% of patients presented proteinuria and/or hematuria. Almost all skin biopsies showed leukocytoclastic vasculitis, with IgA deposits at direct immunofluorescence in more than 50% of cases.

CONCLUSIONS

Our results suggest that the immune response elicited by SARS-CoV2 vaccine or infection could play a role in the development of HSP. Current research suggests a possible role of IgA in immune hyperactivation, highlighted by early seroconversion to IgA found in some COVID-19 patients who develop IgA vasculitis.

Viral Infections May Be Associated with Henoch-Schönlein Purpura

Henoch-Schönlein purpura or IgA vasculitis is the most common type of pediatric vasculitis that may affect adults as well. It is classified as a type of small-vessel vasculitis. It can cause cutaneous and systemic symptoms with a minority of patients developing kidney failure. Little is known about the specific pathophysiology of this disorder, except that it is believed to occur in individuals with abnormally glycosylated IgA1. Serum aberrant IgA1 may form large antigen-antibody complexes which, due to a defective clearance, are able to deposit in the small vessels of the skin, kidney, gut, and joints. A variety of factors, including infectious agents, drugs, and vaccines, have been identified as potential triggers. The majority of cases are preceded by upper respiratory tract infections, and seasonal variations suggest a link with many pathogens. The etiologic agent most frequently associated with IgA vasculitis historically have been group A β-hemolytic streptococcus and common respiratory tract viruses. However, during the current coronavirus pandemic, SARS-CoV-2 infection was identified as a main trigger factor. In addition, IgA vasculitis has been observed following COVID-19 immunization. This review provides insights into the state of the art on the relationship between viral infections, viral vaccines, and Henoch-Schönlein purpura.

A Systematic Review of Histopathologic Surveys on Mucocutaneous Biopsies in Patients Developed COVID-19 Vaccine-Related Dermatologic Manifestations

ABSTRACT

Coronavirus 2 is an infectious agent primarily identified as the cause of a pandemic viral pneumonia. With the mass vaccination against this virus, one of the health issues is the safety of currently available vaccines considering their adverse reactions. This systematic review was conducted to assess and summarize all reported data on histopathologic findings associated with mucocutaneous reactions that developed after COVID-19 vaccination for a better pathophysiology interpretation and clinical management of these reactions. A systematic search was performed in PubMed, Web of Science, and Scopus databases as well as Google Scholar engine for relevant English articles published till July 1, 2022. This review includes 131 studies with a total number of 287 cases. Eruptions that underwent a biopsy were mostly described as erythematous maculopapular, papulosquamous, vasculitis-like, lichenoid, or urticarial lesions. Histopathology revealed spongiosis, interstitial, and perivascular lymphohistiocytic infiltration, erythrocyte extravasation, parakeratosis, endothelial inflammation, and the like. Findings were highly consistent with morbilliform erythema, psoriasiform dermatosis, leukocytoclastic vasculitis, and lichenoid or urticarial drug reactions. The majority of these reactions had a mild nature and were primarily observed in patients with underlying health conditions. Microscopic evaluation was also consistent with transient inflammatory changes, and features like neutrophilic infiltrates, subcorneal pustules, and vasculopathy were less frequently reported than what seen in COVID infection. Therefore, dermatologic reactions developing after vaccination in the general population should not hinder a complete vaccination.

IgA Vasculitis Following COVID-19 Vaccination

As new variants of SARS-CoV-2 continue to emerge worldwide, countries are striving to fully vaccinate their population in a bid to prevent severe disease, subsequent hospitalizations, and the associated strain on their healthcare systems and death. In this context, there is growing evidence of rare, potential side effects associated with COVID-19 vaccines. IgA vasculitis is a systemic, IgA-mediated vasculitis characterized by palpable purpura, arthralgia, abdominal pain, and renal involvement. It is the most common type of vasculitis in childhood, sporadically affecting the adult population. However, there have been multiple reports of IgA vasculitis following vaccination against COVID-19. Herein, we present the case of a 72-year-old patient with palpable purpura that developed two weeks after receiving the Pfizer BioNTech vaccine. Laboratory investigations revealed elevated serum creatinine (2.6 mg/dL), macroalbuminuria (8.6 g/24 h), and macroscopic hematuria. Histopathological examination confirmed necrotizing vasculitis, and a diagnosis of IgA vasculitis was established. Considering the clinical presentation, the laboratory and histopathological findings, and the time interval between the vaccination and the development of symptoms, we strongly believe that IgA vasculitis in this patient arose as a side effect of the Pfizer BioNTech vaccine.

Cutaneous vasculitis and vasculopathy in the era of COVID-19 pandemic

Cutaneous vasculitides encompass a heterogeneous group of clinicopathological entities, which may occur as single-organ vasculitis of the skin or present as skin-limited variant of systemic vasculitis (i.e., skin-limited ANCA-associated vasculitis), and are triggered by various factors, including infections, drugs and vaccines. The COVID-19 pandemic has challenged us with a variety of both disease- and vaccine-associated skin manifestations, including vasculitis. Among the latter, cutaneous small-vessel vasculitis, previously known as leukocytoclastic vasculitis, seems to be the most reported in either scenario, i.e., natural infection and vaccination. Vasculopathy without true vasculitic changes on histology develops in but a minority of cases, mostly severe/critical COVID-19 patients, and appears to be the result of endothelial injury due to pauci-immune thromboembolic mechanisms. Herein, we provide an overview of the available literature on COVID-19-associated and anti-SARS-CoV-2-vaccine-associated cutaneous vasculitis. Although evidence is mostly limited to isolated reports, with a proportion of cases lacking histopathological confirmation, ample overlap with pre-pandemic forms is shown.

Sudden Onset of IgA Vasculitis Affecting Vital Organs in Adult Patients following SARS-CoV-2 Vaccines

IgA vasculitis is an immune complex-mediated small-vessel vasculitis that mainly occurs in children and is characterized by palpable purpura, arthralgia, abdominal pain, and glomerulonephritis. We report three cases of new-onset IgA vasculitis involving major organs in adult patients after they received either the ChAdOx1 viral vector (Oxford/AstraZeneca) vaccine or the messenger RNA-1273 (Moderna) vaccine. These cases suggest that COVID-19 vaccines have the potential to trigger IgA vasculitis and indicate that physicians need to monitor for this possible complication.

Development of IgA vasculitis with severe glomerulonephritis after COVID-19 vaccination: a case report and literature review

With the worldwide spread of the COVID-19 vaccine program during the COVID-19 pandemic, the numbers of reported cases with new-onset or relapsed kidney disease/vasculitis such as minimal change nephrotic syndrome, immunoglobulinA (IgA) nephropathy, and IgA vasculitis (IgAV) that developed after COVID-19 vaccination are increasing. We present the case of a 67-year-old Japanese woman who developed IgAV with purpura on her extremities and trunk in the evening of the day that she received the second dose of the Pfizer-BioNTech COVID-19 vaccine. She subsequently presented with acute kidney injury and nephrotic syndrome, and a kidney biopsy performed 14 days after the second vaccination showed diffuse mesangial and endocapillary glomerulonephritis with necrotizing crescent formation, accompanied by IgA deposition. One steroid pulse plus four administrations of a monthly intravenous cyclophosphamide injection were applied, followed by oral azathioprine during oral steroid tapering. Her response to this treatment was unsatisfactory and intractable for some time. Eventually, her renal function improved and nephrotic syndrome was resolved, while microscopic hematuria and proteinuria at ~ 1 g/gCr remained at 6 months post-vaccination. Unlike the previous milder renal-involved IgAV cases following COVID-19 vaccination, our patient’s case presented severe glomerulonephritis and took a long time to recover despite intensive initial immunosuppressive treatment.

SARS-CoV-2 vaccine-related cutaneous manifestations: a systematic review

To date, over 250 million people have been reportedly infected by COVID‐19 disease, which has spread across the globe and led to approximately 5.1 million fatalities. To prevent both COVID‐19 and viral transmission, DNA‐based/RNA‐based vaccines, non‐replicating viral vector vaccines, and inactivated vaccines have been recently developed. However, a precise clinical and histological characterization of SARS‐CoV‐2 vaccine‐related dermatological manifestations is still lacking. A systematic review of 229 articles was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines, in order to provide an extensive overview of SARS‐CoV‐2 vaccine‐related skin manifestations. Data on demographics, number of reported cases with cutaneous involvement, vaccine, and rash type (morphology) were extracted from articles and summarized. A total of 5941 SARS‐CoV‐2 vaccine‐related dermatological manifestations were gathered. Local injection‐site reactions were the most frequently observed, followed by rash/unspecified cutaneous eruption, urticarial rashes, angioedema, herpes zoster, morbilliform/maculopapular/erythematous macular eruption, pityriasis rosea and pityriasis rosea‐like eruptions, and other less common dermatological manifestations. Flares of pre‐existing dermatological conditions were also reported. Cutaneous adverse reactions following SARS‐CoV‐2 vaccine administration seem to be heterogeneous, rather infrequent, and not life‐threatening. Vaccinated patients should be monitored for skin manifestations, and dermatological evaluation should be offered, when needed.
