Liu Y, Liu H, Bian Q, Zhang S, Guan Y. Parabolic Changes in Pain Scores Among Partial Herpes Zoster Patients: A Retrospective Study. J Pain Res 2024; 17:2191-2201. [PMID: 38939514 PMCID: PMC11208161 DOI: 10.2147/jpr.s461590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 06/18/2024] [Indexed: 06/29/2024] Open
Abstract
Background Herpes zoster (HZ) typically manifests in the acute phase with distinct blisters and severe neuropathic pain. Remarkably, a subset of patients initially presents with only a mild skin rash and moderate pain that gradually intensifies, following a parabolic pattern. Despite being frequently observed in clinical settings, the underlying causes of this trajectory and its potential connection with post-herpetic neuralgia (PHN) remain unclear. Methods To investigate this phenomenon in-depth, we conducted a meticulous retrospective study involving 529 eligible HZ patients. All these patients sought medical care at the Third Central Hospital of Tianjin, China, between January 2020 and December 2023. Results The research identified that 14.6% of the sample (77 patients) experienced pain scores aligning with a parabolic curve. This trend was significantly more prevalent in patients aged 60 and above, accounting for 90.9% of this group, and demonstrated a positive correlation with age. Moreover, 87.0% of these patients had pre-existing medical conditions, highlighting the potential role of comorbidities in influencing the pain trajectory. A concerning 45.5% of patients sought medical attention more than seven days after the onset of symptoms, a delay that could exacerbate neurological damage. Notably, among those following a parabolic pain pattern, 66.2% eventually developed PHN, a considerably higher rate compared to the broader patient population. Conclusion We emphasize that healthcare practitioners meticulously assess patients who initially report lower pain scores for high-risk factors potentially leading to parabolic pain increases, including being over 60 years old, having comorbid conditions, and delaying medical consultation beyond seven days from symptom onset. Early implementation of supplementary pain management therapies may mitigate the risk of PHN development and enhance the quality of life for patients. This study furnishes clinicians with a deeper understanding of the variations in HZ-related pain trajectories, promising to improve treatment approaches and prognoses for HZ patients while paving the way for enriched clinical practice in the future.

Increased Risk of Herpes Zoster in Rheumatoid Arthritis Not Only Due to JAK Inhibitors-Study of 392 Patients from Single University Center. J Clin Med 2024; 13:3121. [PMID: 38892832 PMCID: PMC11172981 DOI: 10.3390/jcm13113121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 04/08/2024] [Accepted: 05/07/2024] [Indexed: 06/21/2024] Open
Abstract
Background/Objectives: Patients with rheumatoid arthritis (RA) have an increased risk of infection. Their risk of presenting herpes zoster (HZ) is 1.5-2 times higher than immunocompetent individuals and disseminated presentation is more frequent. Our aim was to analyze the prevalence and general features of HZ in RA patients. Methods: This was a prospective study of 392 RA patients included in the vaccination program of our hospital between 2011 and 2016, and follow-up continued until December 2020. A diagnosis of HZ was made according to clinical manifestations: skin rash, blisters, paresthesia, and local pain in one or more dermatomes. Results: We studied 392 participants (309 women/83 men), mean age 59 ± 13 years. Every patient was followed-up over a mean period of 137 ± 110 months (range: 42 months-42 years). HZ infection was observed in 30 of 392 (25 women/5 men) patients, age (mean ± SD) 64.7 ± 11.8 years. Prevalence was 7.65% in this period and the incidence rate was 13.22/1000 patients/year. Three patients had facial involvement, one had optic involvement, and one patient presented disseminated HZ. Seven patients presented post herpetic neuralgia treated with gabapentinoids. The main features of RA of these 30 patients were: positive RF (n = 17; 56.6%), positive anti-CCP (n = 13; 43.3%), and erosive disease (n = 10; 33.3%). At HZ infection, the treatments were glucocorticoids (n = 19; 63.3%), conventional DMARDs (n = 15; 50%), biological DMARDs (n = 15; 50%), tofacitinib (n = 2; 6.6%), and upadacitinib (n = 1; 3.3%). Conclusions: HZ is a relatively frequent viral complication in RA patients. In our series, one patient presented disseminated HZ and nearly 25% of patients had post-herpetic neuralgia. Including a HZ vaccine in our vaccination program for RA patients may be beneficial.

Abstract
The share of the elderly population is growing worldwide as life expectancy increases. Immunosenescence and comorbidities increase infectious diseases' morbidity and mortality in older adults. Here, we aimed to summarize the latest findings on vaccines for the elderly against herpes zoster, influenza, respiratory syncytial virus (RSV), COVID-19, and pneumococcal disease and to examine vaccine recommendation differences for this age group in Europe and the United States. PubMed was searched using the keywords "elders" and "vaccine" alongside the disease/pathogen in question and paraphrased or synonymous terms. Vaccine recommendations were also sought in the European and US Centers for Disease Control and Prevention databases. Improved vaccines, tailored for the elderly, mainly by using novel adjuvants or by increasing antigen concentration, are now available. Significant differences exist between immunization policies, especially between European countries, in terms of the recipient's age, number of doses, vaccination schedule, and implementation (mandatory or recommended). Understanding the factors that influence the immune response to vaccination in the elderly may help to design vaccines that offer long-term protection for this vulnerable age group. A consensus-based strategy in Europe could help to fill the gaps in immunization policy in the elderly, particularly regarding vaccination against RSV and pneumococcus.

Abstract
Vaccine development targeting SARS-CoV-2 in 2020 was of critical importance in reducing COVID-19 severity and mortality. In the U.K. during the initial roll-out most individuals either received two doses of Pfizer COVID-19 vaccine (BNT162b2) or the adenovirus-based vaccine from Oxford/AstraZeneca (ChAdOx1-nCoV-19). There are conflicting data as to the impact of age, sex and body habitus on cellular and humoral responses to vaccination, and most studies in this area have focused on determinants of mRNA vaccine immunogenicity. Here, we studied a cohort of participants in a population-based longitudinal study (COVIDENCE UK) to determine the influence of age, sex, body mass index (BMI) and pre-vaccination anti-Spike (anti-S) antibody status on vaccine-induced humoral and cellular immune responses to two doses of BNT162b2 or ChAdOx-n-CoV-19 vaccination. Younger age and pre-vaccination anti-S seropositivity were both associated with stronger antibody responses to vaccination. BNT162b2 generated higher neutralising and anti-S antibody titres to vaccination than ChAdOx1-nCoV-19, but cellular responses to the two vaccines were no different. Irrespective of vaccine type, increasing age was also associated with decreased frequency of cytokine double-positive CD4+T cells. Increasing BMI was associated with reduced frequency of SARS-CoV-2-specific TNF+CD8% T cells for both vaccines. Together, our findings demonstrate that increasing age and BMI are associated with attenuated cellular and humoral responses to SARS-CoV-2 vaccination. Whilst both vaccines induced T cell responses, BNT162b2 induced significantly elevated humoral immune response as compared to ChAdOx-n-CoV-19.

Abstract
PURPOSE To report two patients with herpetic zoster panuveitis and chorioretinopathy with choroidal hypopigmentation. METHODS Retrospective chart review of two patients. RESULTS We report a series of two patients with a history of HZO with orbital inflammation and panuveitis, who developed patchy choroidal depigmentation consistent with a choroidopathy. The lesions were extensive and involved the posterior pole and mid-periphery in both cases. Both cases demonstrated scattered areas of ellipsoid zone loss, and fluorescein angiography showed corresponding late hyperfluorescence. OCTA in one case demonstrated flow voids at the level of choriocapillaris. CONCLUSIONS Our series suggests that herpetic chorioretinopathy may be a relatively benign process that presents late and may involve large areas of the posterior choroid.

Abstract
PURPOSE OF REVIEW Trigeminal postherpetic neuralgia (TG-PHN) is a neuropathic pain condition complicating herpes zoster (HZ) attributed to the trigeminal nerve. It poses significant challenges due to its persistent and debilitating nature. This review explores the clinical characteristics of TG-PHN, analyzes its pathophysiological underpinnings, and addresses existent and potential therapies. RECENT FINDINGS TG-PHN is one of the most common and complex PHN locations. It has distinguishing clinical and pathophysiological characteristics, starting with viral triggered injuries to the trigeminal ganglion (TG) and peripheral tissue and involving the ascending and descending brain modulation pathways. Current therapies include vaccines, oral and topical medications, and interventional approaches, like nerve blocks and neurostimulation. This review covers TG-PHN's clinical and physiological components, treatment options, and potential future targets for improved management. By exploring the complexities of this condition, we aim to contribute to developing more effective and targeted therapies for patients suffering from trigeminal PHN.

Abstract
Cerebral venous sinus thrombosis (CVST) is a rare cause of strokes and is most common in younger patients particularly those less than 50 years of age. It is more common in females than in males and is known to be associated with pregnancy, puerperium, oral contraception, congenital and acquired thrombophilia, and malignancy. Less commonly, it has been shown to be associated with infections and more recently has been found to be associated with COVID-19 infection with thrombocytopenia and the COVID-19 vaccine AstraZeneca. Rare cases have been reported in association with varicella zoster virus (VZV) infection (chickenpox) and its reactivated version of herpes zoster virus (HZV) infection (shingles). We report the case of a 68-year-old lady with herpes zoster ophthalmicus ophthalmoplegia who developed cerebral venous thrombosis (CVT).

Abstract
BACKGROUND We comprehensively compared the therapeutic efficacy of radiofrequency thermocoagulation (RFT) and pulsed radiofrequency (PRF) in the treatment of elderly patients with thoracic postherpetic neuralgia (PHN). MATERIAL AND METHODS We divided 149 elderly patients with thoracic PHN into 2 groups - the RFT group (n=79) and the PRF group (n=70) - based on the radiofrequency mode administered. The Visual Analog Scale (VAS), Athens Insomnia Scale (AIS), Generalized Anxiety Disorder 7 items (GAD-7), and Patient Health Questionnaire 9 items (PHQ-9) were used to analyze the degree of pain, sleep quality, and psychological state of patients before and 1 week, 1 month, 3 months, 6 months, and 12 months after treatment. RESULTS VAS, AIS, GAD-7, and PHQ-9 scores were significantly decreased after RFT and PRF treatment (P<0.001). There was no significant difference in VAS scores between the 2 groups at 1 week and 1 month after treatment (P>0.05). Then, VAS scores in the RFT group were significantly lower than those in the PRF group at 3, 6, and 12 months after treatment (P<0.001). At 1 week after treatment, there were no significant differences in AIS, GAD-7, and PHQ-9 scores between the 2 groups (P>0.05). However, the RFT group had significantly lower AIS, GAD-7, and PHQ-9 scores than the PRF group at 1, 3, 6, and 12 months after treatment (P<0.05). CONCLUSIONS RFT and PRF both effectively reduced pain in the distribution area of thoracic spinal neuropathy and improved the sleep quality and psychological state of elderly patients with thoracic PHN, but RFT had a better long-term effect.

Abstract
In this systematic review with meta-analysis, the efficacy, effectiveness, and safety of the new GSK recombinant zoster vaccine (RZV) were assessed.Twenty three publications reporting on 14 studies were selected, including 2 pivotal RCTs in older immunocompetent adults (ZOE-50 and ZOE-70), 4 RCTs on immunocompromised patients (haematopoietic stem cell transplantation (HSCT), haematological malignancies, solid tumour, and renal transplantation), and 8 observational studies. Vaccine efficacy of RZV against herpes zoster (HZ) and postherpetic neuralgia (PHN) was very high in immunocompetent older adults (respectively 94% and 91.2% in adults ≥50 years and 91.3% and 88.8% in adults ≥70 years). However, the number needed to vaccinate (NNV) was relatively high (between 32 and 36 for HZ and between 261 and 335 for PHN). Slow waning of the vaccine efficacy has been described after a median follow-up of 10 years after vaccination. In patients after HSCT, vaccine efficacy of RZV against HZ was lower compared to immunocompetent adults (68.2%), while vaccine efficacy of RZV against PHN was similar (89.3%). Higher incidences of HZ and PHN in patients after HSCT resulted in higher absolute reduction of cases and lower NNV (respectively 10 and 115). Observational studies confirmed a good vaccine effectiveness, albeit lower than in RCTs (ranging between 70% and 85%). No safety signal was identified neither in RCTs with immunocompetent or immunocompromised adults nor in observational studies and post-marketing surveillance. Increased reactogenicity after RZV vaccination, limited in extent and duration, did not result in low second dose compliance. Conclusion Although vaccine efficacy in RCTs and effectiveness in the real world has been reported to be good, it needs to be stressed that high numbers of immunocompetent adults need to be vaccinated to prevent HZ and PHN. Due to higher incidence, more acceptable NNVs were calculated in immunocompromised adults after HSCT.

Abstract
Background Herpes zoster (HZ) is a viral disease, which is more common among the elderly and immunodeficient individuals, among which approximately 22% of cases might progress to post-herpetic neuralgia (PHN). Hence, this study aimed to assess the knowledge, attitude and practice (KAP) towards HZ and its vaccination among primary health care physicians in Makkah, Saudi Arabia, 2023. Methodology This analytical cross-sectional study used an online pre-validated questionnaire and was conducted from July to August 2023. The target population included physicians working in primary healthcare (PHC) daily clinics in Makkah. Results A total of 153 participants were included in the current study. Of which 90 (58.8%) were females and 120 (78.4%) participants had chicken pox history. Around 123 (80.4%) had previously heard about shingles. The most reported source of information was physicians (63%) followed by the Internet (12.2%). Risk factors for shingles were found to be immunodeficiency (95.1%) and age (78%). Most (88.2%) participants had previously heard about the shingles vaccine and 99 (64.7%) reported that the shingles vaccine is needed even if the patient had chicken pox in the past. Most participants (82.4%) knew that the vaccine should be given to adults aged more than 50 years. About 69 (45.1%) thought that they were extremely likely to get the shingles vaccine if the doctor recommended it. Barriers to shingles vaccination among study participants included participant's perception that they were not at risk of getting shingles (33%) and concerns about vaccines' side effects (27.5%). The average knowledge score about shingles was found to be 9.51 ± 3.14 and the average knowledge score about shingles vaccine was found to be 5.43 ± 1.46. Gender was significantly associated with knowledge score about the vaccine (p-value= 0.028) where females had higher knowledge scores about shingles vaccine as compared to males. Qualification level and current Saudi Commission for Health Specialties (SCFHS) classification were found to be significantly associated with knowledge scores about shingles (p-value = 0.002 and 0.003, respectively). Conclusion A good level of KAP about shingles and its vaccine was found among the study participants. However, few knowledge gaps in methods of protection were assessed. Female gender, married participants and higher SCFHS qualification level were positively associated with higher levels of knowledge and awareness as compared to other groups.

Integrated safety analysis of filgotinib for ulcerative colitis: Results from SELECTION and SELECTIONLTE. Aliment Pharmacol Ther 2023; 58:874-887. [PMID: 37718932 DOI: 10.1111/apt.17674] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 06/04/2023] [Accepted: 07/16/2023] [Indexed: 09/19/2023]
Abstract
BACKGROUND Filgotinib 200 mg (FIL200) is an approved treatment for adults with moderately to severely active ulcerative colitis (UC). AIM To report integrated safety data from the phase 2b/3 SELECTION study (NCT02914522) and its ongoing long-term extension study SELECTIONLTE (NCT02914535). METHODS Safety outcomes were analysed in adults with moderately to severely active UC who received FIL200, filgotinib 100 mg (FIL100) or placebo once daily throughout the 11-week SELECTION induction study, the 47-week SELECTION maintenance study (if applicable) and SELECTIONLTE (if applicable). Exposure-adjusted incidence rates (EAIRs) per 100 censored patient-years of exposure with 95% confidence intervals were reported for treatment-emergent adverse events (AEs). Certain AE data were presented in subgroups, including age and prior biologic exposure status. RESULTS This interim analysis included 1348 patients representing 3326.2 patient-years of exposure. Baseline characteristics of patients entering SELECTION were similar across treatment groups. EAIRs for serious infection, thromboembolic events and major adverse cardiovascular events (MACE) were consistently low across treatment groups. Most patients with MACE had cardiovascular risk factors. The EAIR for herpes zoster was numerically higher for FIL200 than for placebo. Infection incidences were numerically higher in biologic-experienced than biologic-naive patients. Higher incidences of certain AEs in patients 65 years of age or older were as expected. Four deaths occurred, including three cardiovascular deaths, none of which was considered related to filgotinib. CONCLUSION FIL200 and FIL100 were well tolerated with no unexpected safety signals in patients with moderately to severely active UC, regardless of previous biologic exposure or age. CLINICALTRIALS GOV IDENTIFIERS (NCT NUMBERS) NCT02914522, NCT02914535.

Abstract
Ramsay Hunt syndrome is due to reactivation of varicella zoster virus (VZV) dormant in the geniculate ganglion of the facial nerve. The diagnosis is typically based on clinical triad of ipsilateral facial paralysis, otalgia, and vesicles in the auditory canal or the auricle. However, Ramsay Hunt syndrome may occur without skin eruption in up to one third of patients. Moreover, the involvement of other cranial nerves in addition to the facial nerve has been also reported. Herein, we reported a case report of a man who developed a multiple cranial neuropathy caused by VZV reactivation without skin vesicular eruption. The present case underlines a possible diagnostic challenge that clinicians may hit when facing a common disorder such as peripheral facial palsy. Indeed, clinicians must be aware that Ramsay Hunt syndrome may develop without skin vesicular eruption as well it may be complicated by multiple cranial nerve involvement. Antiviral therapy is effective in VZV reactivation for recovery of nerve function.

Front Public Health 2023; 11:1213736. [PMID: 37780417 PMCID: PMC10540814 DOI: 10.3389/fpubh.2023.1213736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Accepted: 09/01/2023] [Indexed: 10/03/2023] Open
Abstract
Herpes zoster (HZ) causes significant morbidity, particularly in older adults. With the advent of a recombinant zoster vaccine, HZ is potentially preventable. However, data on HZ burden and healthcare utilization in primary care populations remains scarce. This study described the prevalence and healthcare utilization in managing HZ in a developed community. A retrospective database review was conducted across a cluster of 8 public primary care clinics in urban Singapore. Data of multi-ethnic Asian patients with a diagnosis code of "herpes zoster" from 2018 to 2020 was extracted from their electronic medical records. Socio-demographic, clinical, visitation, medical leave, prescription, and referral data were analyzed. A total of 2,987 out of 737,868 individuals were diagnosed with HZ over 3 years. The mean age was 59.9 (SD + 15.5) years; 49.2% were male; 78.5% Chinese, 12.2% Malay, and 4.1% Indian. The prevalence was 221, 224, 203 per 100,000 persons in 2018, 2019, and 2020, respectively. The 70 to 79-year age group had the highest prevalence (829/100,000) across 3 years. Oral acyclovir (median daily dose 4,000 mg; median duration 7 days) and topical acyclovir were prescribed in 71.6 and 47.6%, respectively. Analgesia prescribed were gabapentin (41.0%), paracetamol combinations (30.1%), oral NSAIDs (23.7%), opioids (6.0%), and tricyclic antidepressants (1.9%). Most individuals consulted only once (84.3%); 32.7% of them required medical leave and 5.6% had more than 7 days of absenteeism. HZ-related referrals to the hospital were required in 8.9% (4.9% emergency, 2.8% ophthalmology). The findings of this study suggest a need for HZ vaccination among older age groups. Visitation and referral rates were low. The use of topical acyclovir was uncovered, and further research should evaluate the underlying reasons, benefits, and harms of such practice. The use of analgesia combinations may be explored further.

Abstract
BACKGROUND Varicella zoster virus (VZV), which is a human restricted alpha-herpesvirus, causes varicella (chickenpox) and zoster (shingles). The subsequent post-herpetic neuralgia (PHN) due to VZV infection is excruciating for most patients. Thus, developing specific therapeutics against VZV infection is imperative. RNA interference (RNAi) represents an effective approach for alternative antiviral therapy. This study aimed to develop a novel anti-VZV therapeutics based on RNAi. RESULTS In this study, we screened and found the open reading frame 7 (ORF7) of the VZV genome was an ideal antiviral target based on RNAi. Therefore, a novel siRNA targeting ORF7 (si-ORF7) was designed to explore the potential of RNAi antiviral treatment strategy toward VZV. We used a bio-engineering approach to manufacture recombinant siRNA agents with high yield in E. coli. Then, the efficacy of recombinant ORF7-siRNA (r/si-ORF7) in inhibiting VZV infection both in cellular level and 3D human epidermal skin model was evaluated. The r/si-ORF7 was proved to inhibit the VZV replication and reduce the virus copy numbers significantly in vitro. Furthermore, flexible nano-liposomes were established to deliver r/si-ORF7 to 3D human epidermal skin model and found r/si-ORF7 also could inhibit the VZV infection, thus maintaining normal skin morphology. CONCLUSIONS Taken together, our results highlighted that transdermal administration of antiviral r/si-ORF7 was a promising therapeutic strategy for functional cure of VZV infection.

Abstract
BACKGROUND Early intervention reduces the incidence of postherpetic neuralgia (PHN). Typical shingles are easy to diagnose; however, there is no clear diagnostic method for neuralgia symptoms manifested before the onset of the rash, which can easily cause misdiagnosis. This not only increases the patient's pain, medical expenses, and mental burden, but more importantly, delays the valuable time for early treatment of shingles, and increases the probability of complications and PHN. OBJECTIVE In this paper, the diagnostic methods of preherpetic neuralgia were summarized and analyzed, and the current challenges were put forward to provide directions for the early diagnosis of herpes zoster (HZ) in the future. METHODS PubMed, and China National Knowledge Infrastructure (CNKI) libraries were searched using the terms "herpes zoster," "before the blistering," "diagnosis," and "neuralgia." Clinical trials, reviews, and case reports were collected and reviewed. The period of literature search is from 1 January 1980 to 1 October 2022. RESULTS The early diagnosis of herpes zoster neuralgia can reduce misdiagnosis and mistreatment, and timely and effective intervention can significantly reduce the incidence of PHN. The body may possess a mechanism that limits the local breakthrough of the virus in the skin, causing blistering later than the onset of pain. Changes in the plasma proteins of patients with varicella-zoster virus shingles neuralgia may be used as an early diagnostic indicator in patients with HZ neuralgia before eruption. CONCLUSION Early diagnosis of HZ neuralgia before eruption can facilitate timely targeted treatment, thereby reducing the incidence of PHN. Proteomic quantitative analysis and validation results can serve as a simple, micro, rapid, and accurate diagnostic method.

Abstract
Background Postherpetic neuralgia (PHN) is a debilitating complication of herpes zoster, characterized by persistent neuropathic pain that significantly impairs patients' quality of life. Identifying factors that determine PHN susceptibility is crucial for its management. Interleukin-18 (IL-18), a pro-inflammatory cytokine implicated in chronic pain, may play a critical role in PHN development. Methods In this study, we conducted bidirectional two-sample Mendelian randomization (MR) analyses to assess genetic relationships and potential causal associations between IL-18 protein levels increasing and PHN risk, utilizing genome-wide association study (GWAS) datasets on these traits. Two IL-18 datasets obtained from the EMBL's European Bioinformatics Institute database which contained 21,758 individuals with 13,102,515 SNPs and Complete GWAS summary data on IL-18 protein levels which contained 3,394 individuals with 5,270,646 SNPs. The PHN dataset obtained from FinnGen biobank had 195,191 individuals with 16,380,406 SNPs. Results Our findings from two different datasets of IL-18 protein levels suggest a correlation between genetically predicted elevations in IL-18 protein levels and an increased susceptibility to PHN.(IVW, OR and 95% CI: 2.26, 1.07 to 4.78; p = 0.03 and 2.15, 1.10 to 4.19; p =0.03, respectively), potentially indicating a causal effect of IL-18 protein levels increasing on PHN risk. However, we did not detect any causal effect of genetic liability to PHN risk on IL-18 protein levels. Conclusion These findings suggest new insights into identifying IL-18 protein levels increasing at risk of developing PHN and may aid in the development of novel prevention and treatment approaches for PHN.

Abstract
BACKGROUND Chronic post-herpetic neuralgia (CPHN) is a symptomatic condition that afflicts adults and elderly individuals. The chronicity of this symptomatology can be conditioned by the epigenetic modifications induced by the virus on the processes of neurotransmission and sensitivity to pain. The aim of this study is to investigate whether manipulating endogenous bioelectrical activity (EBA), responsible for neurotransmission processes and contributing to the induction of epigenetic modifications, can alleviate pain symptoms. METHODS This manipulation was carried out with the antalgic neuromodulation (ANM) treatment of radioelectric asymmetric conveyer (REAC) technology. Pain assessment before and after treatment was performed using a numerical analog scale (NAS) and a simple descriptive scale (SDS). RESULTS The results of the analysis showed an over four-point decrease in NAS scale score and over one point decrease in SDS scale score, with a statistical significance for both tests of p < 0.005. CONCLUSIONS The results obtained in this study demonstrate how REAC ANM manipulation of EBA can lead to improvement in epigenetically conditioned symptoms such as CPHN. These results should prompt further research to expand knowledge and ensure optimized therapeutic outcomes.

Abstract
Older adults are at an increased risk of vaccine-preventable diseases partly because of physiologic changes in the immune and other body systems related to age and/or accumulating comorbidities that increase the vulnerability to infections and decrease the response to vaccines. Strategies to improve the response to vaccines include using a higher antigenic dose (such as in the high-dose inactivated influenza vaccines) as well as adding adjuvants (such as MF59 in the adjuvanted inactivated influenza vaccine).

Abstract
Herpes zoster (HZ) is a common disease in the aging population and immunocompromised individuals, with a lifetime risk of 20%-30% that increases with age. HZ is caused by reactivation of the varicella-zoster virus (VZV), which remains latent in the spinal dorsal root ganglia and cranial sensory ganglia after resolution of the primary VZV infection. The main focus of HZ management is rapid recovery from VZV infection as well as the reduction and prevention of zoster-associated pain (ZAP) and postherpetic neuralgia (PHN). The use of antivirals against VZV is essential in the treatment of HZ. However, limited antivirals are only licensed clinically for the treatment of HZ, including acyclovir, valacyclovir, famciclovir, brivudine, and amenamevir. Fortunately, some new antivirals against different types of Herpesviridae have been investigated and suggested as novel drugs against VZV. Therefore, this review focuses on discussing the difference in efficacy and safety in the currently licensed antivirals for the treatment of HZ, the applicability of future novel antivirals against VZV, and the preventive or therapeutic effects of these antivirals on ZAP or PHN.

Abstract
Older people are more prone to viral infections, and often have worse outcomes. This was well demonstrated during the COVID-19 pandemic, where a disproportionate number of deaths occurred in the oldest and frailest people. The assessment of the older person with a viral infection is complicated by the high prevalence of multiple comorbidities and sensory or cognitive impairment. They often present with common geriatric syndromes such as falls or delirium, rather than the more typical features of a viral illness in younger people. Comprehensive geriatric assessment by a specialist multidisciplinary team is the gold standard of management, as viral illness is unlikely to present in isolation of other healthcare needs. We discuss the presentation, diagnosis, prevention, and management of common viral infections-respiratory syncytial virus, coronavirus, norovirus, influenza, hepatitis, herpes, and dengue viruses-with special consideration of infections in the older patient.

Burden of opioid use for pain management among adult herpes zoster patients in the US and the potential impact of vaccination. Hum Vaccin Immunother 2022; 18:2040328. [PMID: 35363119 PMCID: PMC9225310 DOI: 10.1080/21645515.2022.2040328] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/30/2022] Open
Abstract
The goal of this research was to describe treatment patterns, health-care resource utilization, and costs for herpes zoster (HZ)-related pain, and to estimate the potential impact of recombinant zoster vaccine (RZV) on avoided HZ cases and HZ-related pain prescriptions. This retrospective claims database study included patients from commercial, Medicare, and Medicaid plans between 2012 and 2017. Subjects with an HZ episode were assigned to three cohorts: “opioid”, “non-opioid”, and “no-treatment” cohorts. Subjects in the opioid cohort were matched to a non-HZ cohort. The potential impact of RZV vaccination on HZ case avoidance and resulting painkiller prescriptions was modeled. Over 25% of subjects with an HZ episode received opioids. Adjusted health-care costs were approximately double in the opioid cohort versus non-opioid or matched non-HZ cohorts. Postherpetic neuralgia, immunocompromised status, and comorbidities increased the risk for opioid prescription. RZV vaccination was predicted to avoid over 19,000 patients from receiving opioid prescriptions for every 1 million adults aged ≥50 years. HZ-related prescriptions of opioids were common and led to increased health care costs. RZV vaccination may potentially reduce opioid prescriptions through decreasing HZ incidence. PLAIN LANGUAGE SUMMARY What is the context? Herpes zoster or shingles and its complications such as postherpetic neuralgia – a painful condition that affects the nerve fibers and skin – may lead to complex pain that can be addressed using opioids in some patients. The recombinant zoster vaccine (RZV) vaccine prevents shingles and, therefore, may reduce the use of opioids and the negative health outcomes and costs associated with it.
What is new? In this retrospective medical claims study, including patients between 2012 and 2017, we
evaluated the receipt of pain medication including opioids in herpes zoster patients, and assessed factors associated with opioid prescription. estimated health care resource utilization and costs associated with opioid use among patients with herpes zoster. assessed the impact of vaccination on opioid prescriptions.
Among subjects receiving opioids, 78.5% started with a weak opioid dose. Dose escalation was uncommon. Postherpetic neuralgia, immunocompromised status, and comorbidities are the main risk factors associated with opioid prescription. Health care costs are almost double in patients with herpes zoster receiving opioids compared with patients without an opioid prescription. In a population of 1 million adults aged 50 years or older, vaccination with the recombinant zoster vaccine could prevent over 19,000 patients from receiving opioids.
What is the impact? Prevention of herpes zoster through vaccination may be a highly effective strategy to reduce opioid prescriptions and costs related to pain management in a susceptible population. Increasing RZV vaccination coverage in adults aged ≥50 years may further reduce potential opioid prescriptions through a decrease in shingles incidence.

Abstract
Herpesviruses affect the development of dementia. We investigated the association between herpes infection and subsequent diagnoses of dementia. Data from the National Health Insurance Service of South Korea were used. Patients aged ≥50 years with the relevant diagnostic codes in the reference year 2009 were included and prospectively reviewed from January 2010 to December 2018. All study participants were followed from the index date until the onset of dementia, death, or the study endpoint. The three cohorts comprised 92,095 patients with herpes simplex virus (HSV) infections, 97,323 patients with varicella-zoster virus (VZV) infections, and 183,779 controls. During the follow-up period, 15,831 (17.19%) subjects with HSV infection and 17,082 (17.55%) VZV-infected subjects, compared to 27,028 (14.17%) control subjects, were subsequently diagnosed with dementia (all, P < .001). The adjusted hazard ratio for developing dementia was found to be 1.18 (95% confidence interval [CI]; 1.16-1.20) in HSV and 1.09 (95% CI; 1.07-1.11) in VZV patients (all, P < .001). HSV1 infections such as oral or ocular subtypes, but not HSV2, anogenital subtype, were associated with dementia, including several subtypes such as Alzheimer's disease (AD), vascular dementia, and dementia with Lewy bodies. VZV infection is also associated with AD. In this Korean nationwide population-based cohort study, both HSV and VZV infections were associated with a higher risk of dementia, particularly AD. Among the subtypes of HSV infection, HSV1 is associated with a risk of dementia. Further studies including appropriate public health interventions could evaluate the causality of these relationships.

Abstract
Background: Herpes simplex virus (HSV) reactivation occasionally develops in the early postoperative period after microvascular decompression (MVD) for trigeminal neuralgia (TN). Therefore, the present study investigated the clinical features of this phenomenon. Methods: The study cohort comprised 200 patients with 125 women aged between 17 and 90 years (median age, 66 years) who underwent MVD for TN between January 2010 and December 2020. Characteristics were compared between patients with and without HSV reactivation and clinical features were analyzed. Results: Twenty patients had HSV reactivation: herpes labialis in 18 and herpes zoster (final diagnosis) in 2. A multivariate analysis revealed independent correlations between postoperative HV reactivation and a previous history of herpes labialis (odds ratios [OR]: 6.32, P = 0.0003) and reoperation for recurrent or persistent pain (OR: 5.06, P = 0.0211). No significant differences were observed in pain relief, postoperative facial numbness, or Barrow Neurological Institute Pain Intensity/Facial Numbness Scores in the past follow-up between patients with and without HSV reactivation. HSV reactivation manifested at a median of the 4th postoperative day (1–10 days) and its location was not related to the preoperative distribution of facial pain. All patients were treated with local acyclovir and were completely cured within 1–2 weeks. Conclusion: HSV reactivation occurred in 10% of patients after MVD including 1% of herpes zoster. A previous history of herpes labialis and reoperation was identified as risk factors for reactivation. Symptoms were completely cured by antiviral drugs within 1–2 weeks. It is important to note that cases of herpes zoster may be confused with cases of HSV after MVD.

Abstract
A 72-year-old woman presented with acute-progressive muscle weakness after a rash in the left upper limb. Muscle weakness was restricted to the left C5 innervated muscles. Short inversion time inversion recovery magnetic resonance imaging (MRI) showed a high-intensity signal in the left C5 nerve root, and nerve ultrasound showed its enlargement. She was diagnosed with segmental zoster paralysis (SZP) and treated with acyclovir and methylprednisolone. Her muscle strength gradually recovered, and the abnormal signal and enlargement in the left C5 nerve root improved. This is the first SZP case of confirmed improvement of abnormal findings on MRI and nerve ultrasound in association with muscle power recovery.

Abstract
Objectives Herpes Zoster (HZ) is a common painful, debilitating condition caused by reactivation of the varicella-zoster virus. It is characterized by a painful skin eruption which is very complex to treat. Studies have reported that HZ negatively affects Quality of Life (QoL), but no large systematic review on this topic has been published to date. This systematic review aims to summarize the current data on patient-reported QoL amongst patients diagnosed with HZ. Methods We searched Medline, Embase, Cochrane Library, CINAHL, and PsycINFO. The primary outcome was the change in percent impairment of QoL compared to normative data. Secondary outcomes were meta-analyses comparing reported QoL to a control group or normative data. Results We assessed a total of 536 studies for inclusion. Thirteen studies were included in the systematic review and five studies in the meta-analyses. The total number of patients was 5472. Conclusions This systematic review and meta-analysis found lower reported QoL amongst patients diagnosed with acute herpes zoster compared to normative values. Our data show that acute herpes zoster significantly reduces the quality of life of the patients affected.

Abstract
Postherpetic neuralgia (PHN) is a common, painful, and long-term complication of herpes zoster (HZ). PHN increases the demand for healthcare services and, previous studies showed that patients who received antiviral agents were less likely to develop PHN. The objective of this study was to compare the efficacy of prodrugs and acyclovir in treating PHN among patients with HZ. The search included the PubMed, Medline, Embase, and Cochrane Center of Register of Controlled Trails databases through February 2022. Clinical trials and randomized controlled trials (RCTs) involving antiviral agent intervention for HZ patients diagnosed with PHN were eligible for inclusion. A meta-analysis was conducted to calculate pooled risk ratios (RRs) with 95% confidence intervals (CIs) with a fix-effect model. Five RCTs with 1147 HZ patients met our eligibility criteria. Our meta-analysis found that there was a significantly lower risk of PHN for members of the prodrugs group (famciclovir and valaciclovir) compared with those who received acyclovir (RR = 0.86, 95%, CI: 0.75 to 0.98, p = 0.03). The review of studies indicated that the efficacy of prodrugs was better than acyclovir for reliving PHN.

Abstract
Critically ill patients are at high risk for organ failure, including that of the integumentary system. Nurses working in intensive care are adept at performing comprehensive assessments that include the skin. Although pressure injury is a well-known complication associated with critical illness, patients may also have debilitating and life-threatening dermatoses. Conditions such as skin failure and medical adhesive-related skin damage are commonly seen in the critically ill. Infectious processes, such as Fournier gangrene, invasive candidiasis, mucormycosis, and herpetic lesions, can result in severe or superimposed critical illness and elude detection. Similarly, cutaneous manifestations of COVID-19 may develop prior to commonly recognized symptoms of infection. Nurses and providers caring for critically ill patients should be aware of common, but less widely known, skin conditions to facilitate early detection and treatment.

Abstract
Herpes Zoster is a viral infection that occurs due to reactivation of the Varicella Zoster virus. A vaccine has been approved for adults aged 50 and above for the prevention of Herpes Zoster and its complications. This study aims to assess the at-risk population’s awareness of the disease and its vaccine, and attitudes and practices toward the vaccine. A quantitative, observational, cross-sectional study was conducted among 420 adults above the age of 50. Non-probability, convenience sampling was used to select participants from public venues. SPSS-25 was used to analyze the data. 64.3% (n = 270) of participants heard of Herpes Zoster. 78.3% (n = 329) did not recognize the link between chickenpox and Herpes Zoster. Multiple linear regression showed that being female, Arab expatriate, or healthcare professional were the only positive predictors of Herpes Zoster knowledge. 14.8% (n = 62) heard of Herpes Zoster vaccine but 96.7% (n = 406) had not taken it. Participants with chronic diseases were 2.064 times more likely to hear about the vaccine than healthy participants (p = 0.026). Multiple linear regression showed that being a healthcare professional was the only significant predictor of Herpes Zoster vaccine knowledge. 28.1% (n = 118) were not willing to take optional vaccines. Those reluctant to take optional vaccines were 26.023 times more likely to take them if recommended by a healthcare professional (p < 0.001). Attitudes toward Herpes Zoster vaccine were generally positive; however, due to lack of knowledge, poor practices were observed. Nationwide campaigns aimed toward at-risk groups can raise awareness on Herpes Zoster and its vaccine, subsequently improving Herpes Zoster vaccination rate.

Abstract
Herpes zoster ophthalmicus (HZO) is a viral condition that presents as a painful vesicular rash in the trigeminal nerve dermatome. In some cases, self-limiting extraocular muscle palsies may occur several weeks after the onset of HZO and last for weeks to months. A 71-year-old man developed a debilitating binocular horizontal diplopia and ptosis about four weeks after the onset of HZO symptoms. He had no uveitis, keratitis, or changes in visual acuity. Examination revealed left abducens palsy and ptosis. Symptoms resolved within eight weeks without any intervention.

Abstract
Chronic pain affects a large part of the population causing functional disability, being often associated with coexisting psychological disorders, such as depression and anxiety, besides cognitive deficits, and sleep disturbance. The world elderly population has been growing over the last decades and the negative consequences of chronic pain for these individuals represent a current clinical challenge. The main painful complaints in the elderly are related to neurodegenerative and musculoskeletal conditions, peripheral vascular diseases, arthritis, and osteoarthritis, contributing toward poorly life quality, social isolation, impaired physical activity, and dependence to carry out daily activities. Organ dysfunction and other existing diseases can significantly affect the perception and responses to chronic pain in this group. It has been proposed that elderly people have an altered pain experience, with changes in pain processing mechanisms, which might be associated with the degeneration of circuits that modulate the descending inhibitory pathways of pain. Aging has also been linked to an increase in the pain threshold, a decline of painful sensations, and a decrease in pain tolerance. Still, elderly patients with chronic pain show an increased risk for dementia and cognitive impairment. The present review article is aimed to provide the state-of-art of pre-clinical and clinical research about chronic pain in elderly, emphasizing the altered mechanisms, comorbidities, challenges, and potential therapeutic alternatives.

Abstract
A series of neuropathic pain conditions have a prevalence in older adults potentially associated with declined functioning of the peripheral and/or central nervous system. Neuropathic pain conditions demonstrate defective cortical excitability and intermissions, which raises questions of the impact of pain on cortical excitability changes and when to deliver repetitive transcranial magnetic stimulation (rTMS) to maximize the analgesic effects. Using prolonged continuous theta-burst stimulation (pcTBS), a relatively new rTMS protocol to increase excitability, this study was designed to investigate pcTBS analgesia and cortical excitability in the context of pain. With capsaicin application, twenty-nine healthy participants received pcTBS or Sham stimulation either in the phase of pain initialization (capsaicin applied) or pain ascending (20 min after capsaicin application). Pain intensity was measured with a visual-analogic scale (VAS). Cortical excitability was assessed by motor-evoked potential (MEP) and cortical silent period (CSP) which evaluates corticospinal excitability and GABAergic intracortical inhibition, respectively. Our data on pain dynamics demonstrated that pcTBS produced a consistent analgesic effect regardless of the time frame of pcTBS. More importantly, pcTBS delivered at pain initialization induced a larger pain reduction and a higher response rate compared to the stimulation during pain ascending. We further provide novel findings indicating distinct mechanisms of pcTBS analgesia dependent on the context of pain, in which pcTBS delivered at pain initialization was able to reverse depressed MEP, whereby pcTBS during pain ascending was associated with increased CSP. Overall, our data indicate pcTBS to be a potential protocol in pain management that could be delivered before the initialization of a pain episode to improve rTMS analgesia, potentially through inducing early corticospinal excitability changes that would be suppressed by nociceptive transmission.

Abstract
Background Herpes zoster neuralgia has a considerable impact on people’s quality of life, especially after the development of postherpetic neuralgia. There are many clinical reports on the treatment of herpes zoster neuralgia, but there have been no special reports on the treatment of herpes zoster involving the neck. Our research focuses on a posterior and upper quarter of the cervical foramina puncture approach for herpes zoster involving the cervical 3–8 (C3-8) nerve region and to consider the safety and efficacy of pulsed radiofrequency combined with steroid injection and ozone injection in this puncture path under CT guidance. Materials and Methods A total of 104 patients with herpes zoster neuralgia involved in the cervical 3–8 nerve region use a posterior and upper quarter of the cervical foramina puncture approach received pulsed radiofrequency combined with steroid and ozone injection to the dorsal root ganglion. The total number of injection procedures, complications, NRS collection (preprocedure, postprocedure at once, two, four and 12 weeks) and drug dose decreases were documented. Results During a total of 257 procedures, 254 procedures successfully completed PRF (3 cases failed to reach the C8 aim points), and the rate of puncture failure was 1.17%. Drug injection was successfully performed in 252 procedures (the injection success rate was 99.21%); the NRSs (preprocedure, postprocedure at once, two, four and twelve weeks) were 5.75 ± 0.682, 2.6 ± 1.023, 2.21 ± 0.925, 1.89 ± 1.162, and 1.43 ± 1.369, and the difference among them was statistically significant. Drug dosages decreased before and after operation and showed statistically significant differences. Conclusion Pulsed radiofrequency combined with steroid and ozone injection for herpes zoster neuralgia involving the C3-8 nerves under CT guidance through a posterior superior quarter approach showed safety and efficacy and had a high success rate, and the NRS decreased significantly.

Abstract
A family cluster of varicella-zoster virus (VZV) infections was reported. Four family members (two children and their parents) continuously develop varicella after the grandmother's herpes zoster. The unvaccinated 16-month-old infant and his mother developed primary varicella with atypical clinical presentation; however, his 28-year-old father presented with a typical generalized vesicular rash. His vaccinated 4-year-old sister was clinically mild, which could be defined as a breakthrough varicella case. They infected the same virus strain but presented various clinical forms.

Abstract
Background CD4+ T cells are a critical component of effective immune responses to varicella zoster virus (VZV), but their functional properties during the reactivation acute vs latent phase of infection remain poorly defined. Methods Here we assessed the functional and transcriptomic properties of peripheral blood CD4+ T cells in persons with acute herpes zoster (HZ) compared to those with a prior history of HZ infection using multicolor flow cytometry and RNA sequencing. Results We found significant differences between the polyfunctionality of VZV-specific total memory, effector memory, and central memory CD4+ T cells in acute vs prior HZ. VZV-specific CD4+ memory T-cell responses in acute HZ reactivation had higher frequencies of IFN-γ and IL-2 producing cells compared to those with prior HZ. In addition, cytotoxic markers were higher in VZV-specific CD4+ T cells than non-VZV-specific cells. Transcriptomic analysis of ex vivo total memory CD4+ T cells from these individuals showed differential regulation of T-cell survival and differentiation pathways, including TCR, cytotoxic T lymphocytes (CTL), T helper, inflammation, and MTOR signaling pathways. These gene signatures correlated with the frequency of IFN-γ and IL-2 producing cells responding to VZV. Conclusions In summary, VZV-specific CD4+ T cells from acute HZ individuals had unique functional and transcriptomic features, and VZV-specific CD4+ T cells as a group had a higher expression of cytotoxic molecules including Perforin, Granzyme-B, and CD107a.

Abstract
Adverse cutaneous reactions to medications are not uncommon and may
resemble viral infection and vice versa, complicating diagnosis. We
describe the case of a 79-year-old male with cholangiocarcinoma with
liver and presumed lung metastasis who presented with abdominal pain
and was admitted with ileitis with partial small bowel obstruction. He
had a widespread papulovesicular rash with hemorrhagic center, mostly
on his face, chest, and back. The rash was initially thought to be a
drug eruption, but was eventually diagnosed via dermatopathological
examination as disseminated varicella zoster virus (VZV) infection.
Steroid treatment was discontinued, and airborne precautions were
initiated. Polymerase chain reaction for VZV was obtained and
intravenous acyclovir treatment was begun. This case of VZV, initially
suspected to be an adverse drug reaction, highlights the importance of
early identification of a highly infectious lesion and the importance
of early infection control measures, given the implications of
exposure to VZV for health care personnel.

Abstract
OBJECTIVES Many comorbidities are associated with adult asthma and may exacerbate the asthma burden of disease. This study aims to investigate the risk for major oral diseases or oral-manifesting diseases in asthmatic compared with non-asthmatic adults. DESIGN We conducted a population-based matched cohort study with a 13.8-year follow-up. SETTING A baseline questionnaire was completed by participants in 1997 and follow-up data were extracted from the national hospital discharge registry of the National Institute for Health and Welfare in Finland from 1997 to 2014. PARTICIPANTS A total of 1394 adults with asthma were matched with 2398 adults without asthma based on sex, age and area of residence. Asthmatic adults were identified from the Drug Reimbursement Register of the Finnish Social Insurance Institution based on a special drug reimbursement right resulting from asthma. Participants without asthma were identified from the Population Register. MAIN OUTCOMES AND MEASURES Oral health-related primary diagnoses were retrieved using codes from the International Classification of Diseases, 10th edition and divided into groups of diseases. Cox's proportional hazards models stratified by matching unit and models matched and adjusted for pack-years, education level and body mass index (when possible) were used to evaluate the matched and further adjusted HRs for diseases comparing asthmatic and non-asthmatic cohorts. RESULTS Adult asthma was associated with a higher risk for any oral-manifesting disease (adjusted HR 1.41, 95% CI 1.11 to 1.80), herpes zoster (adjusted HR 6.18, 95% CI 1.21 to 31.6), benign tumours of the oral cavity and pharynx (matched HR 1.94, 95% CI 1.05 to 3.56) and dermatological diseases (pemphigus, pemphigoid, dermatitis herpetiformis, psoriasis and lichen planus, HR 1.67, 95% CI 1.01 to 2.78). CONCLUSIONS In this study, adult asthmatics experienced a higher risk for a major oral disease or oral-manifesting disease.

Abstract
OBJECTIVES The number needed to vaccinate (NNV) quantifies the effectiveness of vaccination programs. We summarised the published data on NNV against herpes zoster to inform vaccination policies. METHODS We systematically identified studies based on a priori established and registered methods. The main outcomes were the NNV against herpes zoster infection, hospitalisation and mortality. Where appropriate, we conducted meta-analyses using inverse variance, random-effects models, pooling estimated NNV with associated 95% confidence interval (CI). Statistical heterogeneity between pooled estimates was calculated using the I2 statistic. RESULTS Out of 229 unique citations, we included eight nonrandomized studies. Among 50+ year-olds, the NNV against herpes zoster infection using the recombinant subunit vaccine was 11 (95%CI 8-14; I2 = 0%; 3 studies) and variable (I2 = 94.4%; 7 studies) using live attenuated vaccine, ranging from 10 (95%CI 1-19) to 58 (95%CI 49-67). Among 65+ year-olds, the NNV against herpes zoster infection using the recombinant subunit vaccine was 12 (95%CI: 9-15; I2 = 0%; 2 studies) and variable (I2 = 98.5%; 4 studies) using live attenuated vaccine, ranging from 14 (95%CI 5-23) to 75 (95%CI 66-84). The NNV against herpes zoster hospitalisation among 65+ year-olds using the live attenuated vaccine was 280 (95%CI 209-352; I2 = 0%; 2 studies). There was a paucity of data to inform other meta-analyses. CONCLUSION Evidence on the NNV against herpes zoster is scarce. Vaccination with the recombinant subunit herpes zoster vaccine may be more effective than with the live attenuated vaccine in preventing infection among 50+ year-olds. More studies are needed for a stronger evidence base for decision-making.

Abstract
Introduction: The average life span has increased by about two decades in Nepal in last 30 years. With increasing longevity, geriatric health care is gaining much more importance. The statistical data regarding the geriatric skin disorders in Nepalese population is limited. The aim of this study to look for the patterns of skin diseases in the geriatric population of Nepal. Methodology: This is a retrospective, descriptive study where we reviewed the database of patients visiting the dermatology outpatient department of multispeciality teaching hospital in Nepal from August 2016 to July 2017. All patients from the age of 60 and above were included in the study. Data was analyzed using SPSS version 20. Chi square test was done where relevant. Result: Total of 918 patients were included in the study with mean age of 69 years. Most common presentation was that of dermatitis (32.2%) which was followed by infectious condition (29.4%), pruritus (7.4%), psoriasis (4.6%), urticaria (3.9%), miliaria (3.9%) and others. Among the dermatitis, 23% of the patients had hand or feet eczema and 23% had sebohrreic dermatitis. Variability according to weather was noticed with in presentation of sebohrreic dermatitis, dermatophytic infections, miliaria and herpes zoster. Conclusion: This study concludes that dermatitis, infections and pruritus are the most significant dermatological morbidities in our population. It highlights the need of zoster vaccine for our elderly population as it is not a part of the routine vaccination scheme in Nepal.

Abstract
Data of global epidemiology of varicella-zoster virus infection (VZVI) is limited. This study aimed to investigate the burden of VZVI based on the Global Burden of Disease Study 2019 data. The age-standardized rates, including the incidence, death, disability-adjusted life years (DALYs), and the estimated annual percentage changes (EAPC) of VZVI were calculated to evaluate the disease burden of VZVI. The global numbers of incident and death cases due to VZVI were 83,963,744 and 14,553, respectively. The age-standardized incidence rate of VZVI increased slightly all over the world, while the age-standardized death and DALYs rate decreased from 1990 to 2019 (EAPC = -2.31 and -1.61, respectively). The younger age (<5 years old) and older groups had the highest VZVI burden. The high sociodemographic index (SDI) region had the highest age-standardized incidence rates in 2019 (1236.28/100,000, 95% UI: 1156.66-1335.50) and the low SDI region had the lowest incidence (1111.24/100,000, 95% UI: 1040.46-1209.55). The age-standardized death and DALYs rate of VZVI decreased with the increase of SDI. Amongst the 21 geographical regions, the high-income Asia Pacific (1269.08/100,000) region had the highest age-standardized incidence rate in 2019, while Sub-Saharan Africa had the highest age-standardized death and DALYs rate. The global incidence of VZVI has continued to increase in the past three decades, while the age-standardized death and DALYs rates have decreased. More attention should be paid to the younger and older population, as well as low SDI regions. This article is protected by copyright. All rights reserved.

Abstract
INTRODUCTION The chronic neuropathic pain associated with postherpetic neuralgia (PHN) can last for several months or even many years, seriously affecting the affected person's work, sleep, mood, and daily life activities. In generaly, current treatments for PHN are at best limited and unsatisfactory, and adverse reactions are common, especially in elderly patients. Electroacupuncture (EA) is widely used clinically to manage painful diseases, but there remains a lack of evidence to support the effectiveness of EA on PHN. This study is designed to assess the efficacy and safety of EA on PHN, and to provide evidence-based medical evidence for EA treatment of PHN. METHODS This multicenter, prospective, randomized controlled trial will recruit 448 patients with PHN at seven clinical centers. Multicenter stratified variable block randomization will be used, and the eligible patients will be randomly allocated in a ratio of 1:1 to the EA group or sham EA group. The EA group will receive 4 weeks of EA treatment, given as 30-min treatment sessions, once daily, 5 times per week, for a total of 20 treatments; the sham EA group will receive sham EA treatment under the same conditions. PLANNED OUTCOMES The primary outcome measure is the 11-point Numeric Rating Scale pain score at week 4. The secondary outcome measures, including mechanical pain threshold, pain area of PHN, average number of pain episodes, the short-form McGill Pain Questionnaire 2, Zoster Brief Pain Inventory, the Depression, Anxiety, and Positive Outlook Scale, Patient Global Impression of Change, safety of EA, and use of concomitant medications, among others. The primary analysis of the outcomes will be the mixed-effect model with repeated measurement between groups on an intent-to-treat population. TRIAL REGISTRATION Clinicaltrials.gov identifier: NCT04560361. Registered 23 September 2020 ( https://clinicaltrials.gov/ct2/show/NCT04560361?term=NCT04560361&draw=2&rank=1 ).

Risk Factors for Herpes Zoster in Patients with Chronic Kidney Disease: A Case-Control Study. Vaccines (Basel) 2021; 9:vaccines9090963. [PMID: 34579200 PMCID: PMC8473266 DOI: 10.3390/vaccines9090963] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Revised: 08/21/2021] [Accepted: 08/25/2021] [Indexed: 11/17/2022] Open
Abstract
(1) Background: Chronic kidney disease (CKD) increases the susceptibility to the presence of herpes zoster (HZ). Little is known about the risk factors of HZ in CKD patients; (2) Methods: This is a case-control study. CKD patients diagnosed with HZ between January 2015 and June 2021 in a tertiary hospital were identified. One age- and gender- matched control was paired for each case, matched to the date of initial HZ diagnosis. Conditional multiple logistic regression was used to evaluate the risk factors associated with the presence of HZ; (3) Results: Forty-seven HZ patients and controls were identified. In general, about 73.40% (69 out of 94) patients were classified at IV to V stages of CKD. Immunosuppressive agents (p = 0.0012) and dialysis therapy (p = 0.021) were reported more frequently in the HZ cohort. Compared with the control group, the total white cell count and lymphocyte count were significantly lower in the HZ group (p value of 0.032 and 0.003, respectively). The conditional logistics regression model revealed that previous immunosuppressants administration (odds ratio: 10.861, 95% CI: 2.092~56.392, p = 0.005) and dialysis therapy (odds ratio: 3.293, 95% CI: 1.047~10.355, p = 0.041) were independent risk factors of HZ in the CKD population; (4) Conclusions: Dialysis and immunosuppressants therapy were associated with greater risk of HZ disease in CKD patients. Further guideline may highlight the necessity of zoster vaccine for patients with CKD, who undertake associated treatment.

Preferences for herpes zoster vaccination among adults aged 50 years and older in the United States: results from a discrete choice experiment. Expert Rev Vaccines 2021; 20:729-741.

Abstract
BACKGROUND Most adults, and disproportionately fewer African-Americans, have not received herpes zoster (HZ) vaccination despite current recommendations. This study (GSK study identifiers: 208677/HO-17-18066) assessed HZ vaccination preferences among adults aged ≥ 50 years. RESEARCH DESIGN AND METHODS In this discrete choice experiment, respondents chose among a 'no vaccine' option and two HZ vaccine profiles, characterized by seven attributes, in a series of choice questions. Random-parameters logit results were used to predict likely vaccine uptake. Subgroup and latent class analysis of African-American's preferences were performed. RESULTS The preference weight for choosing HZ vaccines over no vaccine was statistically significant among the 1,454 respondents (71.9% whites; 25.2% African-Americans). Out-of-pocket (OOP) cost and vaccine effectiveness (VE) were the most important attributes. The African-American and the non-African-American subgroups had statistically significant differences in preferences (χ2 = 59.91, p < 0.001), mainly driven by OOP cost and VE. Latent class analysis identified three groups of African-American respondents with systematically different preferences; two comprised likely-vaccinators, with one being more cost sensitive at lower price thresholds, and one likely non-vaccinators. CONCLUSIONS For all respondents, HZ vaccine choices were most sensitive to total OOP cost, followed by VE.

McGirr A, Bourgoin T, Wortzman M, Millson B, McNeil SA. An early look at the second dose completion of the recombinant zoster vaccine in Canadian adults: A retrospective database study. Vaccine 2021; 39:3397-3403. [PMID: 34001346 DOI: 10.1016/j.vaccine.2021.04.053] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Revised: 04/08/2021] [Accepted: 04/26/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND In 2017, the two-dose recombinant zoster vaccine (RZV) was authorized for use in Canada for the prevention of herpes zoster (HZ) in adults ≥ 50 years of age (YOA), which is administered 2-6 months apart. The National Advisory Committee on Immunization (NACI) states that a 0, 12-month schedule may be considered if flexibility in the timing of the second dose is needed to improve coverage. This retrospective database study evaluated the second-dose completion of RZV in Canada from January 2018 to May 2019. METHODS Data were obtained from the IQVIA LRx Longitudinal Prescription Database which tracks retail prescriptions of anonymized patients. Patients were followed for 6- or 12-months to evaluate the second dose completion aligned with the licensed RZV dosing schedule and NACI's option for greater flexibility. The primary outcomes were time from first to second dose and the proportion of patients who received the second dose. RESULTS In the 6-month (155,747 patients) and 12-month (55,524 patients) analytic cohorts, 65.0% and 74.9% received the second RZV dose within 2-6 months and 2-12 months after the first dose with a truncated mean time of 97.8 days and 109.8 days between doses, respectively. Variation in completion rates was observed across age and geography, but sex, rurality, and pharmacy type did not impact results. CONCLUSION Second dose completion of RZV in Canada is high but suboptimal. Further research to understand the factors influencing second dose timing and completion will be an important next step to improve series completion.
