Associations of head and neck cancers with herpes zoster in the preceding five years.

This population-based study investigated the risk of having had prior herpes zoster within five years preceding a diagnosis of head and neck cancer. We conducted a case-control study that included 9,191 patients with a diagnosis of head and neck cancer in Taiwan's Longitudinal Health Insurance Database 2010 and 36,764 matched controls. We assessed the odds of patients with head and neck cancer having had a diagnosis of herpes zoster during the five years preceding head and neck cancer using multiple logistic regression analysis. The prevalence of prior herpes zoster among the total sample was 4.6%, 7.9% and 3.8% among patients with and without head and neck cancer, respectively (p < 0.001). The odds ratio of herpes zoster among the head and neck cancer- versus control group was 2.198 (95% CI = 2.001 ~ 2.415) after adjusting for sociodemographic characteristics and hypertension, diabetes, hyperlipidemia, tobacco use disorder, HPV infection, and alcohol dependence syndrome. Statistically significant excess odds were observed for all specific subtypes of head and neck cancer except for sinonasal cancer. Herpes zoster infection within the 5 years preceding a diagnosis of head and neck cancer may be a harbinger of developing head and neck cancer.

Efficacy and Safety of Pulsed Radiofrequency of Dorsal Root Ganglion in Elderly Patient Population With Acute and Subacute Zoster-Related Pain.

Background: Herpes zoster (HZ) is typically characterized by a burning, stabbing pain, hyperalgesia, and allodynia. In some patients, despite the lesions resolving, the pain persists and becomes chronic. If the pain continues for more than 6 months after the onset of the pain phase, this condition is called postherpetic neuralgia (PHN). The frequency and severity of PHN increase with advancing age. The pain in PHN can be severe, sometimes resistant to medications, significantly impacting the patients' quality of life. The elderly patient population cannot tolerate the medications due to their side effects. In this situation, interventional pain treatment should be applied in the elderly patient group who have a high risk of developing PHN compared to other age groups. Method: We included patients over 65 years of age with HZ-related pain who underwent dorsal root ganglion (DRG) pulsed radiofrequency (PRF) within the first 6 months from the onset of pain. We divided these patients into 2 groups: patients who underwent intervention within the first 1 month from the onset of pain and patients who underwent intervention between 1 and 6 months. We recorded medication doses and Numeric Rating Scale (NRS) scores before the procedure and at 1 week, 1 month, 3 months, and 6 months after the procedure. Results: After the DRG PRF treatment, NRS scores improved significantly in both groups (p < 0.05). The mean NRS score in the early DRG PRF group was significantly lower than that in the late DRG PRF group (p < 0.05). The medication doses in the early DRG PRF group were significantly lower than those in the other group (p < 0.05). Conclusions: Interventional pain treatment should be applied as soon as possible in the elderly patient group who do not respond to first-line medical treatment or cannot tolerate medical treatment due to its side effects and who have a high risk of developing PHN compared to other age groups. DRG PRF, applied in the early period of medical treatment-resistant acute HZ, is safe and effective, preventing the progression to PHN.

Understanding herpes zoster vaccine hesitancy and information asymmetry: a qualitative study in China.

Background: Herpes zoster is more prevalent among the older adult due to the age-related immune decline, leading to significant pain and complications. Although vaccination effectively prevents viral infections, vaccine hesitancy remains a major barrier to achieving high vaccination rates.To address this, we conducted a qualitative survey using Vaccine Hesitancy Determinants Matrix and 5C model to understand and improve vaccination rates in this group. Methods: Descriptive qualitative research design based on the philosophical underpinnings of naturalistic inquiry and purposive sampling methodology was conducted on adults aged 50 and above, as well as community health workers. Data were collected through semi-structured, in-depth personal interviews. The interview outline was constructed following a comprehensive review of the literature and consideration of the theoretical framework. Results: Seventeen adults over 50 years and four community healthcare workers were included in this study. The study found that information asymmetry in immunization planning was evident at all stages of vaccine supply, dissemination and demand. The main manifestations included limited access to authoritative information, insufficient community awareness of herpes zoster as a route of vaccination, insufficient vocational training, significant gaps in vaccine knowledge, and high levels of complacency among individual residents. Conclusion: Herpes zoster vaccine hesitancy is prevalent among middle-aged and older adults in China due to information asymmetry, vaccine complacency, inadequate community services, and other multiple layers of factors. Public health strategies should aim to reduce cognitive biases and information gaps by disseminating diverse and credible vaccine information through social media, medical institutions, and offline channels to promote higher vaccination rates.

Primary immunodeficiency-related genes and varicella-zoster virus reactivation syndrome: a Mendelian randomization study.

Background: Currently, evidence regarding the causal relationship between primary immunodeficiency-related genes and varicella-zoster virus reactivation syndrome is limited and inconsistent. Therefore, this study employs Mendelian randomization (MR) methodology to investigate the causal relationship between the two. Methods: This study selected 110 single-nucleotide polymorphisms (SNPs) of primary immunodeficiency-related genes as instrumental variables (IVs). Genetic associations of primary immunodeficiency-related genes were derived from recent genome-wide association studies (GWAS) data on human plasma protein levels and circulating immune cells. Data on genes associated with varicella-zoster virus reactivation syndrome were obtained from the GWAS Catalog and FINNGEN database, primarily analyzed using inverse variance weighting (IVW) and sensitivity analysis. Results: Through MR analysis, we identified 9 primary immunodeficiency-related genes causally associated with herpes zoster and its subsequent neuralgia; determined causal associations of 20 primary immunodeficiency-related genes with three vascular lesions (stroke, cerebral aneurysm, giant cell arteritis); revealed causal associations of 10 primary immunodeficiency-related genes with two ocular diseases (retinopathy, keratitis); additionally, three primary immunodeficiency-related genes each were associated with encephalitis, cranial nerve palsy, and gastrointestinal infections. Conclusions: This study discovers a certain association between primary immunodeficiency-related genes and varicella-zoster virus reactivation syndrome, yet further investigations are warranted to explore the specific mechanisms underlying these connections.

Critical Chest Wall Necrotizing Fasciitis Triggered by Herpes Zoster: A Case Report.

BACKGROUND Necrotizing fasciitis is an aggressive type of skin and soft tissue infection that results in necrosis of subcutaneous tissues, including muscle and fascia. Mixed bacteria, including gas-forming organisms, are usually identified. This report describes a 55-year-old male diabetic patient with herpes zoster involving the thoracic dermatomes complicated by skin infection, necrotizing fasciitis, chest wall abscess, and sepsis. CASE REPORT A 55-year-old man with diabetes mellitus presented with thoracic herpes zoster, initially treated with acyclovir and topical agents. He developed swelling, pain, and fever over the left chest, which was unresponsive to topical treatment. Investigations revealed elevated white blood cells and gas on chest X-ray. Computed tomography confirmed a 13×6×11-cm abscess with gas between the latissimus dorsi and serratus anterior muscles, suggesting necrosis. He received intravenous amoxicillin/clavulanic acid and metronidazole and underwent urgent surgical drainage, yielding 200 mL of pus. Cultures identified antibiotic-sensitive Staphylococcus aureus and Clostridium perfringens. Histopathology confirmed necrotizing tissue with acute bacterial inflammation. He was treated postoperatively with dressings and vacuum-assisted closure, followed by sutures, and was discharged in good condition after 16 days. CONCLUSIONS This case underscores the aggressive nature and potential complications of necrotizing soft tissue infections in patients with diabetes mellitus and herpes zoster. Prompt recognition, early intervention with appropriate antibiotics, and surgical drainage are crucial in managing such infections effectively. The successful use of vacuum-assisted closure therapy underscores its role in facilitating wound healing after debridement. Clinicians should maintain vigilance for necrotizing infections in similar high-risk patients to ensure early intervention and improve clinical outcomes.

The effect of recombinant zoster vaccine on patients with chronic obstructive pulmonary diseases: A multi-institutional propensity score-matched cohort study.

Although the recombinant zoster vaccine (RZV) has demonstrated efficacy in reducing the risk of herpes zoster (HZ) for individuals aged 50 years and older, its effectiveness in patients with chronic obstructive pulmonary disease (COPD) remains uncertain. This study was conducted to assess the effect of RZV on the risk of HZ in COPD patients. A multi-institutional propensity score-matched retrospective cohort study was conducted using the TriNetX Research network, including individuals aged 40 years or older with COPD from January 1, 2018, to December 31, 2022. Patients with a history of HZ or prior zoster vaccination were excluded. The primary outcome was HZ occurrence, with secondary outcomes including severe and nonsevere HZ. After propensity score matching, each 17 431 patients receiving RZV and unvaccinated patients were included. The vaccinated group had a significantly lower risk of HZ compared to the unvaccinated group (HR, 0.62; [95% confidence intervals] 95% CI, 0.51-0.75, p < 0.01). Similar risk reductions were observed for nonsevere HZ (HR, 0.61; 95% CI, 049-0.75, p < 0.01) and severe HZ (HR, 0.53; 95% CI, 0.38-0.73, p < 0.01). Further subgroup analyses demonstrated consistent risk reductions across age (50-59, 60-69, 70-79, and ≥80 years), sex, and comorbidities, except for individual aged 40-49 years. This study confirms the effectiveness of RZV in reducing HZ risk in patients with COPD aged 50 years and older, supporting its administration in this population. However, vaccination rates remain low, highlighting the need for improved vaccination strategies in this high-risk group. Efforts to enhance vaccine uptake are warranted to reduce HZ morbidity.

Herpes zoster triggered by ChAdOx1 nCoV-19 coronavirus vaccine (recombinant).

Herpes zoster is a viral infection caused due to the reactivation of varicella-zoster virus that is localized to a single dermatome unilaterally. The factors responsible for its reactivation are increasing age, immunosuppressive drugs, malignancies, chronic liver and renal diseases. Herpes zoster was found to be one of the cutaneous manifestations of coronavirus disease 2019 (Covid-19). Various skin manifestations post-vaccination are being reported, which include injection site urticarial, maculopapular rash and positive dermographism. We report a patient of herpes zoster triggered by the viral vector (ChAdOx1 nCoV-19) coronavirus vaccine (recombinant).

Acute psoriasis exacerbation by recombinant zoster vaccine: a case report.

Psoriasis is a common chronic inflammatory skin disorder that primarily affects the skin, nails, and joints. Beyond its cutaneous manifestations, psoriasis is associated with several systemic comorbidities. Various factors can trigger or exacerbate psoriasis, including stress, infections, medications, and vaccinations. This article reports what is, to the best of the author's knowledge, the first known case of acute exacerbation of plaque-type psoriasis, presenting as guttate psoriasis (GP), following herpes zoster vaccination. A 52-year-old male with a history of longstanding plaque-type psoriasis developed a sudden flare of GP lesions 2 weeks after receiving the recombinant herpes zoster vaccine. Physicians should be vigilant for potential triggers of psoriasis exacerbation, with the recombinant herpes zoster vaccine being among them.

Herpes zoster as the initial manifestation of varicella-zoster virus infection in a healthy toddler.

Herpes zoster (HZ), commonly known as shingles, is a painful blistering rash in dermatomal distribution, caused by the reactivation of varicella-zoster virus (VZV) that was acquired during a primary varicella infection. While commonly afflicting adults, cases of HZ in paediatric patients are infrequently reported. Such cases are predominantly reported in children who have had prior exposure to VZV, either during pregnancy, early childhood or have been vaccinated with live attenuated VZV. This report presents the first known case to our knowledge of HZ as the initial manifestation of a VZV infection in an immunocompetent toddler in the UK. The report details the chronology of the infection event and discusses the clinical context behind HZ presentations in paediatrics globally. It provides a compelling illustration of the uncommon presentation of VZV infection in an immunocompetent child devoid of antecedent virus exposure, thus meriting acknowledgement and potentially further investigation as to the cause.

Dangers of Herpesvirus Infection in SLE Patients Under Anifrolumab Treatment: Case Reports and Clinical Implications.

BACKGROUND Anifrolumab, a monoclonal antibody targeting the type 1 interferon (IFN-I) signaling pathway, holds promise as a therapeutic intervention for systemic lupus erythematosus (SLE). However, its use is associated with an increased risk of infections, particularly viral infections like herpes zoster (HZ). Results from the clinical trials on anifrolumab show yearly rates of upper respiratory tract infections of 34% and HZ of 6.1%. An increased frequency of other specific viral infections, including herpes simplex virus (HSV), was not reported. CASE REPORT Here, we present 2 cases of patients with SLE treated with anifrolumab, both experiencing severe adverse reactions in the form of disseminated herpesvirus infections, specifically disseminated HSV-2 and varicella zoster virus (VZV, HZ encephalitis). To the best of our knowledge, no previous reports of severe disseminated HSV-2 or HZ have been published in anifrolumab-treated patients. The patient in case 1 experienced a primary HSV-2 infection following anifrolumab treatment, potentially explaining the severity of the infection. The patient in case 2 had a history of previous HZ skin infections, which may have increased her risk of disseminated infection. Both patients recovered from the infections with minor sequelae, but they still require prophylactic antiviral treatment. These cases highlight the critical role of IFN-I immunity in protecting against herpesvirus infections. CONCLUSIONS Thorough risk assessment before anifrolumab initiation, considering the patient's viral infection history, vaccination status, and potential exposure risks, is essential. Administration of recombinant zoster vaccine before anifrolumab therapy may benefit susceptible individuals.

Clinical characteristics and risk stratification for late-onset herpes zoster following allogeneic hematopoietic stem cell transplantation.

The incidence of herpes zoster (HZ) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients is significantly higher than that of the general public. Although routine antiviral prophylaxis is recommended, late-onset HZ has been highlighted, yet limited information is known about its clinical features and predictors. Here, we conducted a retrospective nested case-control study to identify patients with late-onset HZ, defined as a diagnosis of HZ after 1 year of transplantation, among allo-HSCT recipients between 2012 and 2017 at Peking University People's Hospital. Three controls were matched for each patient. A total of 201 patients developed late-onset HZ. Age over 20 years, absence of neutrophil engraftment by 14 days, mental disorders, immunosuppressant use at 1 year, and a peripheral CD4+/CD8+ ratio ≥0.5 at 1 year were independent risk factors, among which the CD4+/CD8+ ratio demonstrated good discriminative power for predicting late-onset HZ. For patients with a CD4+/CD8+ ratio <0.5, patient age, neutrophil engraftment time, mental disorders, and immunosuppressant use were potential risk factors. A stratification algorithm was accordingly established, classifying the transplant recipients into three risk groups. Whether the algorithm could facilitate the administration of posttransplant antiviral prophylaxis merits further validation.

Varicella Zoster Virus disrupts MAIT cell polyfunctional effector responses.

Mucosal-associated invariant T (MAIT) cells are unconventional T cells that respond to riboflavin biosynthesis and cytokines through TCR-dependent and -independent pathways, respectively. MAIT cell activation plays an immunoprotective role against several pathogens, however the functional capacity of MAIT cells following direct infection or exposure to infectious agents remains poorly defined. We investigated the impact of Varicella Zoster Virus (VZV) on blood-derived MAIT cells and report virus-mediated impairment of activation, cytokine production, and altered transcription factor expression by VZV infected (antigen+) and VZV exposed (antigen-) MAIT cells in response to TCR-dependent and -independent stimulation. Furthermore, we reveal that suppression of VZV exposed (antigen-) MAIT cells is not mediated by a soluble factor from neighbouring VZV infected (antigen+) MAIT cells. Finally, we demonstrate that VZV impairs the cytolytic potential of MAIT cells in response to riboflavin synthesising bacteria. In summary, we report a virus-mediated immune-evasion strategy that disarms MAIT cell responses.

Herpes zoster and long-term risk of subjective cognitive decline.

BACKGROUND: Herpes zoster (HZ), commonly known as "shingles," may contribute to cognitive decline through mechanisms such as neuroinflammation or direct neuronal injury. However, evidence on the longitudinal association between HZ and cognitive decline is conflicting and whether the risk differs by APOE ε4-carrier status has not been studied; prospective cohort studies on the association between HZ vaccination and cognitive decline are also lacking. METHODS: We included 149,327 participants from three large cohorts-the Nurses' Health Study (NHS), NHSII, and Health Professionals Follow-Up Study (HPFS)-to prospectively examine the association between HZ and subsequent subjective cognitive decline (SCD). Poisson regression was used to estimate the multivariable-adjusted relative risk (MVRR) of a 3-unit increment in SCD score according to years since HZ compared with participants with no history of HZ. RESULTS: Compared with individuals with no history of HZ, the MVRR (95% CI) of a 3-unit increment in SCD score was significantly and independently higher among individuals with a history of HZ, but the duration of time since HZ when the elevated risk of SCD was statistically significant differed among the cohorts. In NHS, HZ was associated with higher long-term risk of SCD; compared with individuals with no history of HZ, the MVRR (95% CI) of a 3-unit increment in SCD score was 1.14 (1.01, 1.32) for ≥ 13 years since HZ. In NHS II, HZ was associated with higher risk of SCD in both the short-term [MVRR 1.34 (1.18, 1.53) for 1-4 years] and long-term [MVRR 1.20 (1.08, 1.34) for ≥ 13 years since HZ]. In HPFS, an elevated risk of SCD was suggested across all time points. Among the subset of participants with information on APOE ε4, there was a suggestion that the association differed by APOE ε4 carrier status, but the results were not consistent between women and men. Among the subset of women with information on HZ vaccination, there was a suggestion that the long-term risk of SCD may be greater among women who were not vaccinated against HZ. CONCLUSIONS: Data from three large independent cohorts of women and men showed that HZ was associated with higher long-term risk of SCD, and the risk may differ by APOE ε4-carrier status.

Understanding invisible pain in the older adult: a content analysis of social media's representation of herpes zoster vaccine.

Herpes zoster (HZ), a common disease in older adults, affects their quality of life. Therefore, this study aimed to examine the blog posts of HZ-related information on social media platforms to analyze the attitudes and behaviors of residents toward the dissemination of health information. This research used content analysis to focus on Weibo, a representative social media in China, to analyze the content of 1866 blog posts related to herpes zoster (HZ) and herpes zoster vaccine (HZV). According to the consistency test by Cohen's Kappa, four themes were identified: (a) sources, (b) tones, (c) epidemiological information, and (d) extended parallel process model elements. The findings showed that most information on Weibo came from non-professionals, with a neutral tone, and showed the invisible pain of HZ and the effectiveness of HZV through the two largest aspects of prevention and aged protection in epidemiological information. However, current blog posts treat the older adult as invisible individuals, failing to acknowledge them as recipients of the information. Additionally, the cost of the vaccine acts as an invisible economic barrier, contributing to the dissemination of incorrect information about folk remedies. This impacts the older adult's acceptance of health information related to HZV. Thus, the way to share health information with the older adult needs to be improved in the future, and attention should be paid to the transmission of incorrect information to improve their vaccination rates and awareness of health management.
