Can the COVID-19 Vaccine Cause Recrudescence of Herpes Zoster Virus While Taking Antiviral Medication?

Coronavirus disease 2019 (COVID-19) represents a multisystem disease that has caused a devastating global pandemic. The COVID-19 vaccine produced in response to the pandemic has been effective but can have side effects. One well-established condition is the reactivation of herpes zoster (HZ). Various risk factors increase the risk of HZ reactivation such as age, infections, and immunosuppressed states. HZ can have severe complications, including herpes zoster ophthalmicus and postherpetic neuralgia. Here, we present a unique case where a patient experienced HZ reactivation after both primary doses of the COVID-19 vaccine despite receiving early antiviral treatment.

Coexistence of Ophthalmic Shingles and COVID-19 in a Patient Who Applied with Encephalitis Clinic

Varicella zoster virus (VZV) is a member of the herpes virus family and is the causative agent of chickenpox and shingles. While chickenpox, which is the primary infection, is mostly seen in childhood, shingles is located latently in the dorsal root sensory ganglia and cranial nerve ganglia, causing recurrent attacks in adulthood. Shingles may rarely present with neurological complications such as encephalitis. Many diseases are seen in the coexistence of Coronavirus disease-2019 (COVID-19) due to the pandemic. In this case report, it was aimed to draw attention to the ophthalmic varicella zoster virus infection with a different clinical onset accompanied by COVID-19 who presented with the clinic of encephalitis.

Giant Cellulitis-Like Sweet Syndrome Masquerading As Cellulitis and Shingles: A Case Report and Literature Review.

Sweet syndrome (SS) is also known as acute febrile neutrophilic dermatoses. Clinically, SS features fever, arthralgias, and the sudden onset of an erythematous rash. The morphologies of skin lesions in SS are heterogenous, varying from papules, plaques, and nodules to hemorrhagic bullae, which sometimes makes the diagnosis of SS more challenging. We report a 62-year-old obese male with a history of chronic myeloid leukemia in remission for 10 years who presented with a rash for five days. The patient reported prodromal flu-like symptoms with subjective fever, malaise, cough, and nasal congestion followed by a sudden onset, painful, non-pruritic rash. The rash was associated with bilateral hip arthralgias and abdominal pain. The patient denied any recent travel, exposure to sick contacts, or the use of any new medications. Physical examination showed a well-demarcated, non-blanching, confluent, erythematous plaque involving the bilateral buttocks and extending to the lower back and flanks with coalescent "juicy"-appearing plaques and flaccid bullae. No oral or mucosal involvement was noted. Laboratory investigations revealed mild leukocytosis, elevated inflammatory markers, and acute kidney injury. The patient was started on antibiotics given the cellulitis-like skin lesions, leukocytosis with neutrophilia, and elevated inflammatory markers. Dermatology was consulted, who attributed the patient's rash to shingles and recommended initiating acyclovir and obtaining a skin biopsy. However, the patient's rash and arthralgias worsened with anti-viral treatment while awaiting pathology results. Antinuclear antibodies, complement, human immunodeficiency virus, hepatitis panel, blood cultures, and tumor markers were all negative. Flow cytometry showed no evidence of hematopoietic neoplasms. The skin punch biopsy revealed dense neutrophilic infiltration in the dermis with no evidence of leukocytoclastic vasculitis, consistent with acute neutrophilic dermatoses. The diagnosis of giant cellulitis-like Sweet syndrome was established, and the patient was started on prednisone 60 milligrams daily. His symptoms improved promptly with steroid treatment. Our case suggests that SS can camouflage a wide spectrum of diseases, including cellulitis, shingles, vasculitis, drug eruptions, leukemia cutis, and sarcoidosis, which emphasizes the importance of keeping a high index of suspicion for SS when assessing the clinical constellations of fever, neutrophilia, and erythematous plaques suggesting atypical cellulitis. Approximately 21% of Sweet syndrome is associated with malignancy. Sweet syndrome can precede, concur with, or follow the onset of malignancy. Due to the lack of a systematic approach to patients with SS, under-investigation and diagnostic delays are common. Therefore, further screening and continuous monitoring in patients with SS becomes especially important in facilitating the early detection of a potential underlying malignancy and assists in initiating adequate therapy.

Views and Perceptions of People Aged 55+ on the Vaccination Programme for Older Adults in the UK: A Qualitative Study.

Vaccination reduces the risks related to infectious disease, especially among more vulnerable groups, such as older adults. The vaccines available to older adults in the UK through the government-funded programme currently include influenza, pneumococcal, shingles and COVID-19 vaccines. The purpose of the programme is disease prevention and improving wellbeing among the ageing population. Yet, the target population's views of the programme remain unknown. This paper aims to increase the understanding of older adults' perceptions of the vaccination programme available in the UK. A total of 13 online focus groups (56 informants) were carried out for this qualitative study. The findings indicate that getting vaccinated involves personal decision-making processes, which are influenced by previous experiences and interpersonal interactions. Factors related to the wider community and culture are less prominent in explaining vaccination decisions. However, opportunistic vaccination offers, a lack of information and a lack of opportunities to discuss vaccines, especially with healthcare professionals, are prominent factors. The study provides in-depth data about the rationale behind older adults' vaccination decisions in the UK. We recommend that the provision of information and opportunities to discuss vaccines and infectious disease be improved to enable older adults' to make better informed decisions regarding the vaccines available to them.

Combination Therapy for the Treatment of Shingles with an Immunostimulatory Vaccine Virus and Acyclovir.

Practically the entire global population is infected by herpesviruses that establish lifelong latency and can be reactivated. Alpha-herpesviruses, herpes simplex viruses 1 and 2 (HSV-1/HSV-2) and varicella zoster virus (VZV), establish latency in sensory neurons and then reactivate to infect epithelial cells in the mucosa or skin, resulting in a vesicular rash. Licensed antivirals inhibit virus replication, but do not affect latency. On reactivation, VZV causes herpes zoster, also known as shingles. The 76-year-old first author of this paper published an autobiography of his own severe herpes zoster ophthalmicus (HZO) infection with orbital edema, which is considered an emergency condition. Acyclovir (ACV) treatment was complemented with an immunostimulatory viral therapy, which resolved most symptoms within a few days. The orally administered live-attenuated infectious bursal disease vaccine virus (IBDV) delivers its double-stranded RNA (dsRNA) cargo to host cells and activates the natural antiviral interferon (IFN) gene defense system from within the host cells. IBDV has already been demonstrated to be safe and effective against five different families of viruses, hepatitis A virus (HAV), hepatitis B and C virus (HBV/HCV), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and varicella zoster virus (VZV). Here we propose a short phase I/II trial in elderly shingles patients who will be assigned to receive either ACV monotherapy or ACV combined with R903/78, an attenuated immunostimulatory IBDV strain. The primary endpoints will be safety, but the efficacy of the combination therapy against the ACV monotherapy also will be assessed.

Disseminated Herpes Zoster in a COVID-19 Patient

COVID-19 has several different presentations including cutaneous manifestations. In this report, we introduce a case of generalized herpes zoster in a COVID-19 patient. No sign of upper or lower respiratory tract involvement was detected, but due to unexpected dissemination of the lesions, COVID-19 Polymerase Chain Reaction (PCR) was tested and revealed positive. Although the incidence of herpes zoster during COVID-19 infection has been reported previously, none of them was disseminated. Therefore, we recommend that during the pandemic of COVID-19, any unexpected disseminated herpes zoster be considered as a possible case of this disease and be quarantined until the PCR is negative. © 2022 Seventh Sense Research Group®

Reactivation of varicella-zoster virus following mRNA COVID-19 vaccination in a patient with moderately differentiated adenocarcinoma of rectum: A case report.

Herpes zoster which is the reactivation of varicella-zoster virus, a pathogenic human alpha-herpes virus, following primary infection or chicken pox, is known to occur especially in advanced age and in the immunocompromised among other predisposing factors. COVID-19 vaccination-induced immunomodulation is a novel scenario, hypothesized to be a result of shifting of T-lymphocyte population towards vaccine-induced naïve CD8+ subset, offsetting the balance of varicella-zoster virus responsive T-helper cells, thereby defecting the cell-mediated immunity which suppresses the latent varicella-zoster virus. The exact mechanism, however, is still elusive. Herein, we discuss a case of reactivation of varicella-zoster virus following BNT162b2 mRNA COVID-19 vaccine in an elderly female on oral medication for long-term diabetes and hypertension with good control who has undergone local radiotherapy for an underlying adenocarcinoma of rectum awaiting surgical resection, highlighting the key features of pathogenesis of the disease in relation to COVID-19 vaccination with a pertinent survey of the literature. This case report highlights the importance of differentiating vaccine-related cutaneous reactions with clinically more significant adverse events, early specific therapy thus preventing poorer acute and chronic outcomes.

Predictors of herpes zoster vaccination among Australian adults aged 65 and over.

OBJECTIVE(S): To estimate HZ vaccine coverage in Australia among older Australians and to identify potential barriers to vaccination. DESIGN: Analysis of data from three cross-sectional surveys administered online between 2019 and 2020. SETTING AND PARTICIPANTS: Adults aged 65 and over residing in Australia. MAIN OUTCOME MEASURES: Self-reported herpes zoster vaccination. RESULTS: Among the 744 adults aged 65 and over in this sample, 32% reported being vaccinated for HZ, including 23% of participants aged 65-74, 55% of participants aged 75-84, and 0% for participants aged 85 and above. Those who are vaccinated with other immunisations are more likely to have received HZ vaccine, including seasonal influenza (OR = 4.41, 95 % CI: 2.44-7.98) and pneumococcal vaccines (OR = 4.43, 95 % CI: 2.92 - 6.75). Participants with a history of certain conditions, such as stroke (OR = 2.26, 95 % CI: 1.13-4.49), were more likely to be vaccinated against HZ. Participants that reported smoking tobacco daily were less likely to be vaccinated against HZ (OR = 0.48, 95 % CI: 0.26-0.89). Participants were less likely to be vaccinated against HZ if they preferred to develop immunity 'naturally' (OR = 0.29, 95 % CI: 0.15 - 0.57) or expressed distrust of vaccines (OR = 0.34, 95 % CI: 0.13-0.91). CONCLUSION(S): Further research is required to understand the barriers to HZ vaccine uptake. Increasing the funding eligibility for those who are at risk of complications from shingles, or lowering the age of eligibility, may increase vaccine coverage.

Adherence to Herpes Zoster (Shingles) Catch-Up Campaign at the Romagna Local Health Authority (Italy), a Multi-Center Retrospective Observational Study.

Herpes Zoster (shingles) is an infection that occurs when varicella-zoster virus reactivates from the latent state. Incidence and severity of Herpes Zoster disease increase with age. Antiviral drugs are the elective treatment; however, prevention of disease reactivation through effective and safe vaccines is available in Italy out-of-pocket from age 65 onwards. The Romagna Local Health Authority (northern Italy) administered catch-up vaccinations in March-May 2022 for immunizations not performed during the COVID-19 pandemic. In this study, adherence rates to the catch-up campaign and recall activities adopted in two centers were investigated. The uptakes for only the catch-up vaccinations were 11.4% and 12.4%. Having suffered from Herpes Zoster or having family members who suffered from it would not seem to be drivers of increased uptake. Although sending text-messages to all involved patients was the main motivation for vaccine uptake (85.7-95.1%), word of mouth and web/news advertising also contributed to adoption in Center No. 2. In both centers, the need for greater synergy between public health departments and general practitioners to engage their patients emerged, as did the need for additional recall measures. Studying the main drivers of vaccine hesitancy, especially at the local level, can help in targeting campaigns and catch-up activities in order to achieve widespread acceptance.

Prediction of Waste Disposal During Covid-19 Using System Dynamics Modeling

Sound and effective solid waste management practices are important to mitigate health risks and protect the surrounding environment. Proper Municipal Solid Waste (MSW) management practices are especially important during the COVID pandemic. Since the beginning of the COVID pandemic different waste disposal and recycling behaviors are observed in Regina, the capital city of Saskatchewan. It is believed the changes of waste disposal rate at Regina landfill is related to the new hygienic guidelines, more opportunities for work from home, distinct consumer behaviors, and COVID related regulations and recommendations. Waste generation and recycling behaviors are complex and multi-dimensional. The objective of this study is to model waste disposal rate at the City of Regina landfill using a System Dynamics (SD) model. The proposed SD model will help us better manage the City of Regina’s human resources during the pandemic and estimate the demand of additional personal protective equipment required for the waste management workers. In the present work, a total of 7.5 years of waste disposal data is collected, consolidated, and verified. Socio-economical parameters such as GDPs and population at Regina were also collected during the study period from 2013 to 2020. The model is built using stock-flow diagram to illustrate the effects of various inter-related variables on the waste generation behaviors. Construction and demolition (C&D), Grit, Asphalt Shingles Only, Asphalt Shingles Mixed and Treated Biomedical wastes data are used in the SD model. Results show that waste generation has affected by the pandemic and there is a general increase in amount of waste generation. The modeling results are important because it helps us predict the amount of MSW during and after the pandemic. © 2023, Canadian Society for Civil Engineering.

Magnetic stimulation in the treatment of postherpetic neuralgia – a case report

Herpes zoster (shingles) is an acute infectious viral disease that may develop in individuals who have previously had chickenpox. Unlike chickenpox, shingles is more likely to occur in adults, with the risk increasing with age. The paper presents treatment outcomes in a 63-year-old patient with severe thoracic pain persisting for 5 weeks. The treatment included 15 sessions of magnetic stimulation using a low induction variable magnetic field, performed once a day, which allowed to significantly reduce pain, as assessed using the Laitinen Pain Scale. The inclusion of magnetic stimulation as an element of comprehensive therapy also improved the patient’s quality of life, as assessed with EuroQol (a score of 25 before the therapy vs. 65 after the therapy).

Varicella zoster meningitis following COVID-19 vaccination: a report of two cases.

Most of the adverse effects reported in patients who have received COVID-19 vaccines have been mild. However, possible serious adverse effects are being monitored cautiously. There have also been a number of case reports of reactivation of varicella zoster infection within 28 days after immunization with mRNA COVID-19 vaccines. A few cases have also been reported after viral vector and inactivated COVID-19 vaccination. The incidence of meningitis following varicella zoster virus infection is rare. In the current study, we report two cases of male patients who received two different types of COVID-19 vaccine (inactivated and viral vector) and developed varicella zoster meningitis within 10 days after vaccination.

Cellular Immune Response after Vaccination with an Adjuvanted, Recombinant Zoster Vaccine in Allogeneic Hematopoietic Stem Cell Transplant Recipients.

Hematopoietic stem cell transplant (HSCT) recipients have a high risk of developing primary varicella-zoster virus (VZV) infection and reactivation. VZV vaccination may prevent infection and reactivation. In the current study, recipients of allogeneic HSCT (34 females, 45 males) were vaccinated with adjuvanted, recombinant zoster vaccine Shingrix™, which contains the VZV glycoprotein E. Cellular immunity against various VZV antigens was analyzed by interferon-gamma ELISpot. Peripheral blood mononuclear cells (PBMC) of recipients with versus without prior shingles (n = 36 and n = 43, respectively) showed approximately twofold higher VZV-specific responses prior to and post vaccination. After the first and second vaccination, ELISpot responses towards the glycoprotein E were significantly higher in males versus females (median of spots increment 18 versus 1 and 17 versus 4, respectively, p ≤ 0.02 each). Multivariate analysis showed that shingles and sex both impacts significantly on VZV immunity. Whereas vaccination-induced changes could hardly be detected after stimulation with a whole VZV antigen, there was a significant increase in responses towards glycoprotein E after vaccination (p < 0.005). These data indicate that vaccination with Shingrix™ augmented cellular, VZV-specific immunity in HSCT recipients. Shingles and male sex could both be identified as factors leading to increased immunity.

Characteristics of herpes zoster infection in patients with COVID-19: a systematic scoping review.

BACKGROUND: Although there is literature reporting correlations between varicella zoster virus (VZV) infections and COVID-19, insufficient evidence exists in this regard. This scoping review aims to identify the existing evidence regarding clinical characteristics of primary VZV infection or reactivation in COVID-19. METHODS: Following the PRISMA Extension for Scoping Reviews, MEDLINE and EMBASE were searched for all peer-reviewed articles with relevant keywords including "Zoster," "Herpes," and "COVID-19" from their inception to November 20, 2021. RESULTS: A total of 19 articles with three observational studies and 16 case reports or series were included. Primary VZV infections or reactivation were observed in 25 patients. Forty-eight percent of the patients had disseminated VZV infection. The median time of VZV-related rash after the onset of respiratory symptoms was 7.0 days (interquartile range: 0-18.8). Those with COVID-19 and primary VZV infection or reactivation had low lymphocyte counts with a median of 0.67 × 103 /µl. CONCLUSION: This scoping review identified uncertainty and a lack of strong evidence to see the association between primary VZV infection or reactivation and COVID-19. However, those with COVID-19 may be more likely to have disseminated VZV, which poses an additional challenge from an infection prevention standpoint. Future studies are warranted to determine the association between primary VZV infection or reactivation and long-term consequences related to COVID-19.

Apparent lack of association of COVID-19 vaccination with Herpes Zoster.

Purpose: Herpes zoster (HZ) has been identified as a potential association with the BNT162b2 COVID-19 vaccination. This study evaluated this possible association in a cohort of patients receiving the vaccination. Methods: Epic electronic health records of adult patients who received at least one COVID-19 vaccination between January 12, 2020 and 9/30/2021 within the NYU Langone Health were reviewed to analyze a new diagnosis of herpes zoster within 3 months before compared to 3 months after vaccination. Results: Of the 596,111 patients who received at least one COVID-19 vaccination, 716 patients were diagnosed with HZ within three months prior to vaccination, compared to 781 patients diagnosed within 3 months afterwards. Using the chi-square test for independence of proportions, there was not a statistically significant difference in frequency of HZ before (proportion: 0.0012, 95% CI: [0.0011, 0.0013]) vs. after vaccination (proportion: 0.0013, 95% CI: [0.0012, 0.0014]); (p = 0.093). Conclusions and importance: This study did not find evidence of an association between COVID-19 vaccination and a new diagnosis of HZ. We encourage health care professionals to strongly recommend COVID-19 vaccinations per Centers for Disease Control (CDC) recommendations and vaccination against HZ according to Food and Drug Administration (FDA) approval for the recombinant zoster vaccine.

Increased Risk of Herpes Zoster in Adults ≥50 Years Old Diagnosed With COVID-19 in the United States.

Background: Case reports have described herpes zoster (HZ) in patients with coronavirus disease 2019 (COVID-19). However, this constitutes low-quality evidence for an association. We therefore performed a retrospective cohort study to assess the risk of developing HZ following a COVID-19 diagnosis. Methods: We compared the HZ incidence in ≥50-year-olds diagnosed with COVID-19 vs those never diagnosed with COVID-19. We used data from the US MarketScan Commercial Claims and Encounters and Medicare Supplemental (3/2020-2/2021) and Optum Clinformatics Data Mart (3-12/2020) databases. Individuals with COVID-19 were exact-matched 1:4 to those without COVID-19 by age, sex, presence of HZ risk factors, and health care cost level. Adjusted incidence rate ratios (aIRRs) were estimated by Poisson regression. Results: A total of 394 677 individuals ≥50 years old with COVID-19 were matched with 1 577 346 individuals without COVID-19. Mean follow-up time after COVID-19 diagnosis and baseline characteristics were balanced between cohorts. Individuals diagnosed with COVID-19 had a 15% higher HZ risk than those without COVID-19 (aIRR, 1.15; 95% CI, 1.07-1.24; P < .001). The increased HZ risk was more pronounced (21%) following COVID-19 hospitalization (aIRR, 1.21; 95% CI, 1.03-1.41; P = .02). Conclusions: We found that COVID-19 diagnosis in ≥50-year-olds was associated with a significantly increased risk of developing HZ, highlighting the relevance of maintaining HZ vaccination.

Dermatological manifestation can be an early sign in Covid-19: Report of three cases with a novel manifestation masquerading Steven Johnson syndrome.

Various dermatological manifestations have been observed in patients with Coronavirus disease (COVID-19) infection ranging from maculopapular rashes, urticaria, chickenpox-type lesions, chilblain-like, distal-limb ischemia, and livedo racemosa. While most of these cutaneous findings are self-resolving, they may aid in the timely diagnosis of this infection. We are reporting three patients presenting with dermatological features resembling (i) varicella zoster, (ii) herpes labialis, and (iii) Steven Johnson Syndrome (SJS) who were subsequently diagnosed with Covid-19 infection. The skin lesions disappeared after successful treatment of Covid-19.

Modeled impact of the COVID-19 pandemic and associated reduction in adult vaccinations on herpes zoster in the United States.

Due to COVID-19, vaccinations dropped in 2020 and 2021. We estimated the impact of reduced recombinant zoster vaccine (RZV) use on herpes zoster (HZ) cases, complications, and quality-adjusted life-year (QALY) losses among older adults. Various scenarios were compared with Markov models using data from national sources, clinical trials, and literature. Missed series initiations were calculated based on RZV distributed doses. In 2020, 3.9 million RZV series initiations were missed, resulting in 31,945 HZ cases, 2,714 postherpetic neuralgia cases, and 610 lost QALYs. Scenarios further projected disease burden increases if individuals remain unvaccinated in 2021 or the same number of initiations are missed in 2021. Health professionals should emphasize the importance of vaccination against all preventable diseases during the COVID-19 era.
