Oh H, Tan C, Williams C, Giannelos N, Ng C. Public health impact of herpes zoster vaccination on older adults in Singapore: a modeling study. Hum Vaccin Immunother 2024; 20:2348839. [PMID: 38804600 PMCID: PMC11135959 DOI: 10.1080/21645515.2024.2348839] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Accepted: 04/24/2024] [Indexed: 05/29/2024] Open
Abstract
In Singapore, population aging and rising life expectancy are increasing herpes zoster (HZ) burden, which may be reduced by vaccination. The present study modeled the public health impact of HZ vaccination in Singapore using ZOster ecoNomic Analysis (ZONA) model adapted with Singapore-specific key model inputs, where available. Base case analysis was conducted in adults ≥ 50 years of age (YOA), exploring three vaccination strategies (no vaccination, recombinant zoster vaccine [RZV], zoster vaccine live [ZVL]) under mass vaccination setting (30% coverage). Scenario and sensitivity analyses were performed. Out of 1.51 million adults in 2021 (base case population), 406,513 (27.0%) cases of HZ, 68,264 (4.5%) cases of post-herpetic neuralgia (PHN), and 54,949 (3.6%) cases of other complications were projected without vaccination. RZV was estimated to avoid 73,129 cases of HZ, 11,094 cases of PHN, and 9,205 cases of other complications over the subjects' remaining lifetime; ZVL would avoid 17,565 cases of HZ, 2,781 cases of PHN, and 1,834 cases of other complications. The number needed to vaccinate to prevent one case of HZ/PHN was lower for RZV (7/41) than ZVL (26/163). Among all five age-stratified cohorts (50-59/60-64/65-69/70-79/≥80 YOA), RZV (versus no vaccination/ZVL) avoided the largest number of cases in the youngest cohort, 50-59 YOA. Results were robust under scenario and sensitivity analyses. Mass vaccination with RZV is expected to greatly reduce the public health burden of HZ among Singapore individuals ≥ 50 YOA. Findings support value assessment and decision-making regarding public health vaccination strategies for HZ prevention in Singapore.

Abstract
Herpesviruses antagonize host antiviral responses through a myriad of molecular strategies culminating in the death of the host cells. Pseudorabies virus (PRV) is a significant veterinary pathogen in pigs, causing neurological sequalae that ultimately lead to the animal's demise. PRV is known to trigger apoptotic cell death during the late stages of infection. The virion host shutdown protein (VHS) encoded by UL41 plays a crucial role in the PRV infection process. In this study, we demonstrate that UL41 inhibits PRV-induced activation of inflammatory cytokine and negatively regulates the cGAS-STING-mediated antiviral activity by targeting IRF3, thereby inhibiting the translocation and phosphorylation of IRF3. Notably, mutating the conserved amino acid sites (E192, D194, and D195) in the RNase domain of UL41 or knocking down UL41 inhibits the immune evasion of PRV, suggesting that UL41 may play a crucial role in PRV's evasion of the host immune response during infection. These results enhance our understanding of how PRV structural proteins assist the virus in evading the host immune response.

Abstract
BACKGROUND AND OBJECTIVE Recombinant zoster vaccine (RZV) is approved in adults for the prevention of herpes zoster. The effect of RZV in moderating the severity of breakthrough cases of herpes zoster has been noted but not explicitly quantified before. In this study, a meta-analysis was undertaken to estimate differential utility losses between unvaccinated (Placebo) and vaccinated (RZV) subjects in breakthrough cases of herpes zoster from three RZV clinical trials. METHODS Differential utility losses between the two groups were estimated in units of quality-adjusted life-years (QALYs), leveraging aggregate patient data from the ZOE-50 (NCT01165177), ZOE-70 (NCT01165229), and ZOE-HSCT (NCT01610414) clinical trials. Differential utility losses and the ratio of mean utility losses were analyzed using random-effects and fixed-effects meta-regression models. RESULTS The mean QALY loss differences between the unvaccinated (Placebo) and vaccinated (RZV) groups were 0.008, 0.004, and 0.011 in the ZOE-50, ZOE-70, and ZOE-HSCT studies, respectively, yielding an overall estimated difference of 0.007 (95% confidence interval 0.002-0.012) QALYs. Quality-adjusted life-year loss in the vaccinated group was estimated to be 35.5% of the value in the placebo group. A sensitivity analysis estimated an overall difference of 0.005 (95% confidence interval 0.001-0.009) QALYs, corresponding to 48.6% of the QALY loss value in the placebo group. CONCLUSIONS Recombinant zoster vaccine is effective in alleviating disease severity in breakthrough cases of herpes zoster. The results may be useful in distinguishing QALY losses between vaccinated and unvaccinated cohorts in health economics studies, particularly cost-effectiveness analyses.

Abstract
OBJECTIVES The aim of this study was to update previously estimated public health impact and cost effectiveness of recombinant zoster vaccine (RZV) for the prevention of herpes zoster (HZ) in Canadians aged ≥50 years using longer-term RZV efficacy and waning data and real-world coverage and completion. METHODS A multicohort Markov model was used to conduct a cost-utility analysis comparing RZV with no HZ vaccination among Canadians aged ≥50 years. Real-world data were used for first-dose coverage (17.5%) and second-dose completion (65%). Vaccine efficacy and waning data were applied from up to 8-year follow-up from the ZOE-50 and ZOE-70 clinical trials. Incremental costs and benefits were calculated using a lifetime horizon from the healthcare payer (base case) and societal perspectives. A discount rate of 1.5% was applied to costs and quality-adjusted life-years (QALYs). RESULTS The model estimated that RZV would prevent 303,835 HZ cases, 83,256 post-herpetic neuralgia (PHN) cases, 39,653 other complications, and 99 HZ-related deaths compared with no HZ vaccination. Incremental cost-effectiveness ratios (ICERs) were estimated to be $27,486 and $22,097 per QALY (2022 Canadian dollars [CAN$]) from the healthcare payer and societal perspectives, respectively. The base-case ICER was most sensitive to a lower percentage of initial HZ cases with PHN. Almost all probabilistic sensitivity analysis simulations (98.1%) resulted in ICERs CONCLUSIONS RZV is expected to remain a cost-effective option for Canadian adults aged ≥50 years when using longer-term RZV efficacy and waning estimates, although the estimated public health impact was smaller than in the previous analysis (due to lower coverage/completion estimates).

Abstract
BACKGROUND Postherpetic neuralgia (PHN) is the most common chronic complication of herpes zoster (HZ) and results in severe refractory neuropathic pain. This study aimed at evaluating the efficacy of premedication with duloxetine in the prevention of PHN. METHODS The PROCESS trial is a multicenter, randomized, open-label, blinded-endpoint trial used a 1:1 duloxetine:control ratio. Adults 50 years or older with HZ who presented with vesicles within 72 hours were recruited. The primary outcome was the incidence of PHN at 12 weeks. PHN was defined as any pain intensity score other than 0 mm on the visual analog scale (VAS) at week 12 after the onset of the rash. The secondary outcomes were the number of participants with VAS >0 and VAS ≥3. The modified intention-to-treat (mITT) principle and per-protocol (PP) principle were used for the primary outcome analysis. RESULTS A total of 375 participants were randomly assigned to the duloxetine group and 375 were assigned to the control group. There was no significant difference in the incidence of PHN in the duloxetine group compared with the control group in the mITT analysis (86 [22.9%] of 375 vs 108 [28.8%] of 375; P = .067). PP analysis produced similar results. However, there were significant differences between the 2 groups in the number of participants with VAS >0 and VAS ≥3 (P < .05 for all comparisons). CONCLUSIONS Although absolute prevention of PHN does not occur, this trial found that premedication with duloxetine can reduce pain associated with HZ, and therefore can have clinically relevant benefits.

Abstract
The objective of this study was to critically review the cost-effectiveness (CE) of the recombinant zoster vaccine (RZV) against herpes zoster (HZ). A literature review was conducted in PubMed, Embase, and Cochrane between January 1, 2017, and February 28, 2022, and on select public healthcare agency websites to identify and collect data from CE studies comparing RZV to zoster vaccine live (ZVL) or to no vaccination. Study characteristics, inputs, and outputs were collected. The overall CE of RZV was assessed. RZV vaccination against HZ is cost-effective in 15 out of 18 studies included in the present review. Varying incremental cost-effectiveness ratios (ICERs) observed may be associated with different assumptions on the duration of protection of RZV, as well as different combinations of structural and disease-related study (model) inputs driving the estimation of ICERs.

Abstract
Herpes zoster (HZ) brings a significant economic burden. The HZ vaccine was introduced in China for the first time in 2020, and there is a lack of up-to-date information on the hospitalization costs and characteristics prior to vaccination. This study aimed to describe the characteristics and economic burden of HZ inpatients in Hunan Province, China, and analyze the factors influencing the length of stay (LOS) and costs. This was a retrospective study and we extracted information from the Chinese National Health Statistics Network Reporting System on HZ inpatients in Hunan Province, China from 2017 to 2019. Spatial join tools and Global or Local Moran's Index were used for the geographic analysis of hospitalized HZ incidence. Multivariate linear regression models were used to analyze the factors influencing LOS and costs. There were 44,311 HZ inpatients included in this study, incurring a total of $31,857,734 medical costs. These patients had a median LOS of 8 days and a median expenditure of $573.47. Older age, more comorbidities, and the presence of complications with nervous system involved were all significantly associated with longer LOS and higher costs. HZ infection resulted in a large direct medical cost and heavy disease burden, especially in patients with advanced age or underlying medical conditions. The HZ vaccine has the potential to effectively reduce the disease burden and should be widely popularized especially among high-risk groups.

Abstract
INTRODUCTION Herpes zoster (HZ) is a condition that results from the reactivation of the varicella zoster virus (VZV). Several diseases have been reported to increase the risk of developing HZ and postherpetic neuralgia (PHN). The objective of this study is to analyze the prevalence and risk factors for HZ and PHN in the most frequent chronic respiratory diseases, which are chronic obstructive pulmonary disease (COPD), asthma, lung cancer and obstructive sleep apnea (OSA). METHODS We conducted an observational, retrospective, non-interventional study between January 2012 and December 2020 based on data from the Castilla-La Mancha Regional Health System in Spain. We used the Savana Manager 3.0 artificial intelligence-enabled system to collect information from electronic medical records. RESULTS 31765 subjects presented a diagnosis of HZ. Mean age was 64.5 years (95%CI 64.3-64.7), and 58.2% were women. The prevalence of HZ showed an increasing trend in patients over the age of 50. A risk analysis adjusted for sex and comorbidities in COPD, asthma, lung cancer and OSA presented a higher risk of developing HZ in the first three (OR 1.16 [95%CI 1.13-1.19], 1.67 [1.63-1.71], 1.68 [1.60-1.76], respectively), which further increased in all three when associated with comorbidities. Regarding postherpetic neuralgia, an increased risk was only observed related to COPD and lung cancer (OR 1.24 [95%CI 1.23-1.25], 1.14 [1.13-1.16], respectively), further increasing when associated with comorbidities. CONCLUSIONS In a standard clinical practice setting, the most prevalent respiratory diseases (asthma, COPD and lung cancer) are related to a higher risk of HZ and PHN. These data are fundamental to assess the potential impact of vaccination in this population.

Abstract
OBJECTIVE Review the evidence on the incidence and impact of herpes zoster among people living with HIV and the potential impact of recombinant zoster vaccine for people aging with HIV. METHODS Narrative review. RESULTS Although antiretroviral therapy has substantially reduced the risk of herpes zoster among people living with HIV, they remain at an increased risk compared with the general population. Among people aging with HIV, aging per se is now the main risk factor for herpes zoster. Beyond pain, herpes zoster is also associated with a risk of sight-threatening complications in case of trigeminal involvement, disseminated diseases and stroke. Post-herpetic neuralgia is also a potential threat to the quality of life of people aging with HIV. The recombinant zoster vaccine has demonstrated high and sustained efficacy in the prevention of herpes zoster, post-herpetic neuralgia, and other herpes zoster complications in the general population. Immunogenicity data among people living with HIV with high CD4+ T-cell count and controlled viral load are comparable to those among the general population. Real-life effectiveness data indicate high vaccine efficacy among immunocompromised patients other than people living with HIV. High vaccine price, vaccine hesitancy, and limited disease and vaccine awareness represent potential hurdles for high vaccine uptake among people aging with HIV in Europe. CONCLUSIONS Herpes zoster, and its complications, is a vaccine-preventable disease of aging people. Given its impact on quality of life, herpes zoster prevention using recombinant zoster vaccine is a safe strategy to be considered in every person aging with HIV.

Abstract
Purpose The aim of this study was to analysis of the opioid use of opioid native zoster-related pain (ZRP) patients to evaluate the impact of opioid use on pain control and quality of life improvement based on the clinical database. Patients and Methods We conducted a retrospective cohort study to identify opioid native patients who were hospitalized in the pain department between May 1, 2020, and May 1, 2021. The primary outcomes were persistent opioid use after discharge, visual analogue scale (VAS) at the admission, VAS remission rate during hospitalization, VAS score and quality of life at follow-up. Then, we assessed patient-level risk factors for persistent opioid use after the discharge. Results A total of 350 patients met the inclusion criteria. Of those patients, 255 (72.9%) were administered with opioid during hospitalization, and 95 (27.1%) patients were not. Opioid prescription during hospitalization was independently associated with increased odds of persistent use after the discharge (adjusted odds ratio, 20.74; 95% CI, 4.504-95.474; P < 0.01). In the two groups, the VAS score at admission and the VAS score at follow-up were different. In the group with opioids during hospitalization, the persistent opioid use after discharge was more common (38% vs 2.1%) compared to patients without opioids, and VAS remission rate during hospitalization was less, restrictions on daily life, work or housework, and social activities were more common, and mood, diet and sleep were worse, respectively. Conclusion Opioids prescription during hospitalization might increase the risk of chronic opioid use in opioid native ZRP patients, and it has limited benefits in pain control and quality of life improvement. Even though PHN was painful and intractable, the use of opioids should also be more cautious, and strict follow-up, management in this population.

Abstract
Introduction Patients with neuropathic pain (NP) report a higher impairment of quality of life and sleep than patients with chronic pain without neuropathic characteristics. These include somatosensory peculiarities like allodynia, a surrogate marker for central sensitization. Objectives This study aimed to investigate the relation between symptoms of central sensitization and sleep disturbances in patients with NP. Methods Within this cross-sectional study, data sets of 3339 patients with chronic NP syndromes (painful diabetic polyneuropathy, n = 543; postherpetic neuralgia, n = 1480) or complex regional pain syndromes (CRPS, n = 1316) were analyzed. Neuropathic pain symptoms were assessed with the painDETECT questionnaire (PD-Q), depression with the Patient Health Questionnaire-9, and sleep impairment with items of the Medical Outcomes Study Sleep Scale in 4 subscales. The association of demographic/clinical data, somatosensory phenotype, depression, and pain intensity with sleep impairment was assessed by unadjusted Spearman correlation analyses and multivariable regression analyses. Results Sleep impairment was observed in all pain aetiologies although with some significant differences in the single sleep items. The intensity of the individual PD-Q items differed to some extent between the 3 pain entities, whereas the PD-Q sum score was similar. Thermal hyperalgesia and burning assessed by the PD-Q were significantly associated with sleep disturbance, adequacy, and quantity but not with sleep somnolence. Only depression and self-reported allodynia had a significant relation to all 4 sleep elements. Conclusion Beside depression, allodynia as a surrogate marker hints to a possible impact of central sensitization on the sleep disruption of patients with NP.

Abstract
Post-herpetic neuralgia (PHN) is a chronic pain that is difficult to treat and lasts a long time, which poses a threat to patients' physical and mental health (MH) and quality of life. To analyze the effectiveness of extracorporeal shock wave (ESW) combined with pregabalin on PHN and its impact on PHN patients' quality of life with the help of a random number table. Totally 164 PHN patients were assigned to a control group (n = 82) or an observation group (n = 82). The observation group was given pregabalin combined with ESW treatment, while the control group was only given pregabalin. In the 2 groups, the general clinical data of the patients were compared. The inflammation levels including erythrocyte sedimentation rate (ESR), CRP, lymphocyte count and albumin level in both groups were compared prior to and following therapy. In addition, the difference between pretreatment and post-treatment in the 2 groups was compared with respect to neuralgia and quality of life. After treatment, the observation group exhibited much lower ESR and CRP but quite higher lymphocyte count and albumin level relative to the control group (P < .05). Additionally, the improvement in visual analogue scale (VAS) scores and short form 36 (SF-36) scale scores including role-emotional (RE), MH, physical function (PF), general health (GH), bodily pain (BP), social function (SF), vitality (VT), and role-physical (RP) scores in the 2 groups were pronounced following treatment, which was more apparent in the observation group (P < .05). The combination of ESW with pregabalin can reduce the inflammation, improve the quality of life of PHN patients and effectively relieve their neuralgia.

Abstract
Background In recent years, the incidence of herpes zoster has risen steeply, the exact pathogenesis of the acute pain and the transformation into postherpetic neuralgia are still obscure, and the absence of effective management remains a major therapeutic challenge. The purpose of this study was to perform a qualitative and quantitative bibliometric analysis of the 100 most cited papers on herpes zoster. Materials and methods Related literature were retrieved from the Web of Science Core Collection. Excel and VOSviewer software were applied to quantitatively analyze, and construct the bibliometric network charts. Results The Top 100 most-cited papers published between 2000 and 2018 showed a fluctuating downward trend. The most studies were published in the year of 2000 (n = 12). The article entitled "A vaccine to prevent herpes zoster and postherpetic neuralgia in older adults" from Oxman MN, was the most-cited publication. The United States was the most contributing country, followed by the United Kingdom, and Italy. Finland occupied the highest citations per publication (CPP). The University of Colorado topped the list of institutions with the most publications with 18 articles and also had the most citations (average citations: 281.78 per article). Myron J Levin from the University of Colorado School of Medicine is the most published and most cited researcher overall, whereas Duke University's John W Gnann tops the list in terms of average CPP. Conclusion In terms of the quantity of T100 articles, researchers, and organizations, the US is the predominant country. The most T100 papers were published in the special journal Clinical Infectious Diseases. The most academic focus remain the remedies for postherpetic neuralgia and vaccine development for individualized groups.

Abstract
BACKGROUND Postherpetic neuralgia (PHN) is the most frequent and a difficult-to-treat complication of herpes zoster (HZ). Its symptoms include allodynia, hyperalgesia, burning, and an electric shock-like sensation stemming from the hyperexcitability of damaged neurons and varicella-zoster virus-mediated inflammatory tissue damage. HZ-related PHN has an incidence of 5%–30%, and in some patients, the pain is intolerable and can lead to insomnia or depression. In many cases, the pain is resistant to pain-relieving drugs, necessitating radical therapy.
CASE SUMMARY We present the case of a patient with PHN whose pain was not cured by conventional treatments, such as analgesics, block injections, or Chinese medicines, but by bone marrow aspirate concentrate (BMAC) injection containing bone marrow mesenchymal stem cells. BMAC has already been used for joint pains. However, this is the first report on its use for PHN treatment.
CONCLUSION This report reveals that bone marrow extract can be a radical therapy for PHN.

Abstract
Patients presenting with herpes zoster (HZ) to emergency departments (EDs) across the United States represent a significant number of visits and have pain that is difficult to manage, sometimes even requiring opioid medications for adequate analgesia. Ultrasound-guided nerve blocks (UGNBs) are becoming more integrated into the ED physician's tool box for a multimodal approach to analgesia in various indications. Here we describe a novel use of the transgluteal sciatic UGNB for treatment of HZ pain along the S1 dermatome. A 48-year-old woman presented to the ED with right-sided leg pain associated with a HZ rash. After initially failing non-opioid pain management, the ED physician performed a transgluteal sciatic UGNB for our patient, leading to successful complete resolution of her pain, with no adverse effects reported. Our case highlights the potential role of using the transgluteal sciatic UGNB for analgesia related to HZ-related pain, as well as its potential opioid-sparing benefits. Although UGNBs require a baseline understanding of ultrasound technique for procedural guidance, this skillset has recently been incorporated as core competency within emergency medicine training in the United States. UGNBs should therefore be considered in the multimodal analgesic armamentarium for the ED treatment of HZ pain.

Abstract
Economic stability is thought to be associated with health outcomes. Income changes may affect the occurrence of herpes zoster (HZ), which is a neurocutaneous disease caused by the varicella-zoster virus. This retrospective cohort study aimed to examine the associations between annual income changes and incident HZ in a Japanese population. The analysis was conducted using a database of public health insurance claims data linked with administrative data containing income levels. The study population comprised 48,317 middle-aged persons aged 45-64 years from five municipalities, and participants were followed-up from April 2016 until March 2020. Income changes were categorized as income unchanged (income in the year of interest remained within 50% of income in the previous year), income rise (income increased by more than 50% from the previous year to the year of interest), and income drop (income decreased by more than 50% from the previous year to the year of interest). Cox proportional hazards regression analyses were performed to calculate the hazard ratios of HZ for income drop and income rise (reference: income unchanged) as time-varying variables. Covariates included age, sex, and immune-related conditions. The results showed that income drop was significantly associated with a higher hazard ratio (1.15, 95% confidence interval: 1.00-1.31) for HZ. In contrast, income rise was not associated with HZ. A subgroup analysis revealed that the lowest baseline income group had a significantly higher risk of HZ when experiencing an income drop (HR: 1.56, 95% CI: 1.13-2.15). As zoster vaccination is voluntary and vaccination coverage in middle-aged persons is low in Japan, our findings indicate that it may be advantageous to promote and subsidize voluntary vaccinations for middle-aged people with low baseline income who have experienced substantial income reductions in order to reduce the risk of HZ.

Cost-Effectiveness Analysis of Tofacitinib Compared with Biologics in Biologic-Naïve Patients with Moderate-to-Severe Ulcerative Colitis in Japan. PHARMACOECONOMICS 2023; 41:589-604. [PMID: 36884164 PMCID: PMC10085930 DOI: 10.1007/s40273-023-01254-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Accepted: 02/12/2023] [Indexed: 05/10/2023]
Abstract
OBJECTIVE Tofacitinib is an oral Janus kinase inhibitor approved for the treatment of ulcerative colitis (UC). The objective of this study was to evaluate the long-term cost-effectiveness of tofacitinib versus current biologics, considering combinations of first-line (1L) and second-line (2L) therapies, from a Japanese payer's perspective in patients with moderate-to-severe active UC following an inadequate response to conventional therapy and in those who were naïve to biologics. METHODS A cost-effectiveness analysis was conducted during the time horizon specified in the Markov model, which considers a patient's lifetime as 60 years and an annual discount rate of 2% on costs and effects. The model compared tofacitinib with vedolizumab, infliximab, adalimumab, golimumab, and ustekinumab. The time of active treatment was divided into induction and maintenance phases. Patients not responding to their biologic treatment after induction or during the maintenance phase were switched to a subsequent line of therapy. Treatment response and remission probabilities (for induction and maintenance phases) were obtained through a systematic literature review and a network meta-analysis that employed a multinomial analysis with fixed effects. Patient characteristics were sourced from the OCTAVE Induction trials. Mean utilities associated with UC health states and adverse events (AEs) were obtained from published sources. Direct medical costs related to drug acquisition, administration, surgery, patient management, and AEs were derived from the JMDC database analysis, which corresponded with the medical procedure fees from 2021. The drug prices were adjusted to April 2021. Further validation through all processes by clinical experts in Japan was conducted to fit the costs to real-world practices. Scenario and sensitivity analyses were also performed to confirm the accuracy and robustness of the base-case results. RESULTS In the base-case, the treatment pattern including 1L tofacitinib was more cost-effective than vedolizumab, infliximab, golimumab, and ustekinumab for 1L therapies in terms of cost per quality-adjusted life year (QALY) gained (based on the Japanese threshold of 5,000,000 yen/QALY [38,023 United States dollars {USD}/QALY]). The base-case results demonstrated that the incremental costs would be reduced for all biologics, and decreases in incremental QALYs were observed for all biologics other than adalimumab. The incremental cost-effectiveness ratio (ICER) was found to be dominant for adalimumab; for the other biologics, it was found to be less costly and less efficacious. The efficiency frontier on the cost-effectiveness plane indicated that tofacitinib-infliximab and infliximab-tofacitinib were more cost-effective than the other treatment patterns. When infliximab-tofacitinib was compared with tofacitinib-infliximab, the ICER was 282,609,856 yen/QALY (2,149,157 USD/QALY) and the net monetary benefit (NMB) was -12,741,342 yen (-96,894 USD) with a threshold of 5,000,000 yen (38,023 USD) in Japan. Therefore, infliximab-tofacitinib was not acceptable by this threshold, and tofacitinib-infliximab was the cost-effective treatment pattern. CONCLUSION The current analysis suggests that the treatment pattern including 1L tofacitinib is a cost-effective alternative to the biologics for patients with moderate-to-severe UC from a Japanese payer's perspective.

Abstract
ABSTRACT Herpes zoster (HZ) and HZ-associated pain greatly affect patients' quality of life, particularly in older and immunocompromised adults, for whom comorbidities and polypharmacy are often reported. Three phase III, randomized, placebo-controlled clinical trials have reported the adjuvanted recombinant zoster vaccine (RZV) as highly efficacious in preventing HZ and reducing pain severity in healthy adults ≥50 years old (Zoster Efficacy Study [ZOE]-50 study, NCT01165177) and ≥70 years old (ZOE-70; NCT01165229) and in immunocompromised adults ≥18 years old undergoing autologous hematopoietic stem cell transplantation (ZOE-HSCT; NCT01610414). Here, we investigated efficacy of RZV in reducing (i) the duration of clinically significant pain (Zoster Brief Pain Inventory pain score ≥3) and (ii) HZ-associated pain medication use and duration of use in participants with confirmed HZ ("breakthrough cases") from the 3 studies. Recombinant zoster vaccine effectively reduced the duration of clinically significant HZ-associated pain during HZ episodes by 38.5% ( P -value: 0.010) in the ZOE-HSCT study. Although a similar trend was observed in the ZOE-50 and ZOE-70 studies, the results were not statistically significant because of the high vaccine efficacy (VE) against HZ resulting in rare breakthrough cases. VE in reducing pain medication use (39.6%; P -value: 0.008) and duration of medication use (49.3%, P -value: 0.040) was reported in the ZOE-70 study; corresponding positive VE estimates were observed in the ZOE-50 and ZOE-HSCT studies but were not statistically significant. Data reported here demonstrate efficacy of RZV in reducing HZ-associated pain duration and pain medication use in breakthrough cases, thereby improving quality of life of those with HZ.

Abstract
OBJECTIVE The novel Coronavirus (COVID-19) has continued to present a significant burden to global public health efforts. The purpose of this study was to estimate the health-related quality of life, disability, and health status of individuals with self-reported long COVID at various lengths of recovery. METHODS We conducted a cross-sectional online survey of individuals with self-reported long COVID. Participants were asked to complete the five-item EuroQOL EQ-5D-5L and EQ visual analog scale, the 12-item World Health Organization Disability Assessment Schedule (WHODAS) 2.0 and the 10-item Patient Reported Outcome Measurement Information System (PROMIS) Global Health v1.2 short form. Descriptive and inferential statistics were used to characterize the responses and differences across groups. RESULTS Eighty-two participants from 13 countries completed the EQ-5D-5L, 73 completed the WHODAS 2.0 and 80 participants completed the PROMIS. The mean EQ-5D-5L utility score was 0.51. The mean WHODAS score was 49.0. In the previous 30 days, participants reported their symptoms affected them for a mean of 24 days, they were totally unable to carry out usual activities for 15 days, and they cut back or reduced activities for 26 days. The mean PROMIS physical health and mental health scores were 10.7 and 8.6, respectively, corresponding to below-average health. No significant differences were detected across time or according to severity of acute infection. CONCLUSIONS Long COVID presents a significant chronic health burden to adults in the US and abroad. This health burden may persist for many months post-acute infection.

Effectiveness of Live Attenuated Varicella-Zoster Vaccine in Adults Older than 50 Years in Japan: A Retrospective Cohort Study. Vaccines (Basel) 2023; 11:vaccines11020259. [PMID: 36851138 PMCID: PMC9958742 DOI: 10.3390/vaccines11020259] [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: 11/24/2022] [Revised: 01/13/2023] [Accepted: 01/17/2023] [Indexed: 01/27/2023] Open
Abstract
Background: In Japan, freeze-dried live attenuated varicella-zoster vaccine BIKEN is available for adults aged ≥50 years to prevent herpes zoster (HZ). A prospective cohort study of 1200 healthy adults and 300 patients with underlying illness confirmed vaccine safety between 2016 and 2017. However, evidence of vaccine effectiveness (VE) is limited. Methods: VE against HZ and postherpetic neuralgia (PHN) was evaluated in the vaccinated cohort of the previous safety study in a follow-up study between 2021 and 2022 and compared with unvaccinated family members. Self-administered questionnaires determined retrospective experiences of HZ and PHN diagnosis. Logistic regression estimated the VE by calculating the outcome odds ratio (OR) in vaccinated vs. unvaccinated groups: VE = (1 - OR) × 100(%). Results: Overall, 1098 vaccinated and 518 unvaccinated subjects were analysed. Between 2016 and 2022, 26 vaccinated (2.4%) and 22 unvaccinated (4.2%) subjects reported HZ diagnosis, and 3 vaccinated (0.3%) and 2 unvaccinated (0.4%) subjects reported PHN. Adjusted VE against a clinical diagnosis was 41% for HZ [-6% to 67%], with marginal significance, and 16% [-408% to 86%] for PHN. Stratification by age, sex, or comorbidities had an adjusted VE against HZ of ~40%, which was similar between strata. Conclusion: Freeze-dried live attenuated varicella-zoster vaccine reduces the risk of HZ regardless of age, sex, or comorbidities.

Pain Fluctuations of Women with Subacute Herpetic Neuralgia During Local Methylcobalamin in Combination with Lidocaine Treatment: A Single-Blinded Randomized Controlled Trial. J Pain Res 2023; 16:1267-1284. [PMID: 37090764 PMCID: PMC10115195 DOI: 10.2147/jpr.s404713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 04/12/2023] [Indexed: 04/25/2023] Open
Abstract
Purpose To evaluate the efficacy and pain fluctuations of methylcobalamin in combination with lidocaine local injection treatment for subacute herpetic neuralgia (SHN). Methods Seventy-nine women (60.4 ± 2.7 years) with thoracic SHN were enrolled and randomized to receive a combination of methylcobalamin and lidocaine local injection (MI, N=40), or a combination of lidocaine patch 5% and oral methylcobalamin (PO, N=39) for four weeks. Repeated-measures analyses of variance were used to evaluate the effect on pain levels. Generalized estimation equations were used to analyze the cause-effect relationship between pain fluctuations and influencing factors. Results At the treatment endpoint, the group, treatment time, and group interacted with treatment time effects of the pain scores and area were statistically significant (P<0.001), The pain scores were 2.9 ±0.9 (MI) and 4.3 ± 1.5 (PO). 80.00% (MI) or 28.21% (PO) of patients had pain scores ≤ 3, the odds ratio was 2.84 (95% CI: 1.68 to 4.79). The incidence of postherpetic neuralgia was 5.0% (2/40) at 3 months. Pain fluctuated repeatedly during treatment. The pain fluctuation increased from 8.75 log folds in the afternoon, to 79.85 log folds at night. With the ADLs level increasing from 1 to 3, the pain fluctuated from 4.28 to 17.70 log folds. Allodynia, itching, sleep quality, and ADLs were the significant influencing factors (P<0.05). Conclusion This study validated the efficacy of methylcobalamin combined with lidocaine for SHN, and confirmed that pain levels in patients with SHN had an obvious circadian rhythm. ADLs were an important cause of pain fluctuations.

Abstract
Reactivation of latent varicella-zoster virus (VZV) causes herpes zoster (HZ), which is commonly accompanied by acute pain and pruritus over the time course of a zosteriform rash. Although the rash and associated pain are self-limiting, a considerable fraction of HZ cases will subsequently develop debilitating chronic pain states termed postherpetic neuralgia (PHN). How VZV causes acute pain and the mechanisms underlying the transition to PHN are far from clear. The human-specific nature of VZV has made in vivo modeling of pain following reactivation difficult to study because no single animal can reproduce reactivated VZV disease as observed in the clinic. Investigations of VZV pathogenesis following primary infection have benefited greatly from human tissues harbored in immune-deficient mice, but modeling of acute and chronic pain requires an intact nervous system with the capability of transmitting ascending and descending sensory signals. Several groups have found that subcutaneous VZV inoculation of the rat induces prolonged and measurable changes in nociceptive behavior, indicating sensitivity that partially mimics the development of mechanical allodynia and thermal hyperalgesia seen in HZ and PHN patients. Although it is not a model of reactivation, the rat is beginning to inform how VZV infection can evoke a pain response and induce long-lasting alterations to nociception. In this review, we will summarize the rat pain models from a practical perspective and discuss avenues that have opened for testing of novel treatments for both zoster-associated pain and chronic PHN conditions, which remain in critical need of effective therapies.

Comparison of the Efficacy and Safety of Temporary Spinal Cord Stimulation versus Pulsed Radiofrequency for Postherpetic Neuralgia: A Prospective Randomized Controlled Trial. Pain Res Manag 2022; 2022:3880424. [PMID: 36267666 PMCID: PMC9578922 DOI: 10.1155/2022/3880424] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 09/05/2022] [Accepted: 09/19/2022] [Indexed: 11/30/2022]
Abstract
Objectives The objective of this study is to compare the safety and effectiveness of the temporary spinal cord stimulation (SCS) versus pulsed radiofrequency (PRF) in treating postherpetic neuralgia (PHN). Methods From September 1, 2019, to May 30, 2020, 44 PHN patients admitted to the Pain Department of the Foshan First People's Hospital, China were enrolled in this study. The patients were randomly assigned to SCS and PRF groups in a ratio of 1 : 1 and were given respective therapy for 8 days. Rash, in all patients, was located in the trunk and extremities of the spinal nerve (C4-L5), and the pain intensity was greater than or equal to 7 points on the VAS scale. Subsequently, we evaluated the visual analogue scale (VAS), efficiency rate (ER), complete remission rate (CRR), daily sleep interference score (SIS), patient health questionnaire (PHQ-9), generalized anxiety disorder assessment (GAD-7), bodily pain (BP), and physical function (PF) sections of the 36-item short-form health survey (SF-36) at the following time points: presurgery, as well as 1 week, 1 month, 3 months, and 6 months postsurgery. Results The final analysis was performed on 40 patients (n = 20 SCS cohort, and n = 20 PRF cohort). Both cohorts exhibited comparable baseline values (P > 0 : 05). Particularly, they were similar in age, sex, pain duration, involved dermatome, and comorbidity. Among the variables that demonstrated marked improvements from presurgical data to 1 week postsurgery were VAS, ER, CRR, SIS, PHQ-9, GAD-7, as well as BP and PF of the SF-36 in both cohorts. In addition, this improvement persisted for 6 months. There was no complication related to surgery in any of our patients. Conclusion Based on our analysis, SCS exhibited better efficacy and safety than PRF. This study was prospectively registered in the Chinese Clinical Trial Registry (ChiCTR2100050647).

Short-term spinal cord stimulation is an effective therapeutic approach for herpetic-related neuralgia—A Chinese nationwide expert consensus. Front Aging Neurosci 2022; 14:939432.

Abstract
Purpose Short-term spinal cord stimulation (st-SCS) has been widely used to treat herpetic-related neuralgia (HN) in China for several years, but is still heavily debated as it has no strong evidence in clinical application. Therefore, a questionnaire survey among the Chinese pain specialist workgroup of the Chinese Neuromodulation Society and Chinese Medical Doctor Association was carried out to achieve a consensus about the clinical use of st-SCS for HN treatment. Methods The contents of the questionnaire include basic information about doctors (hospital level, work experience, training, procedure numbers, etc.), efficacy, indications, and contraindications of st-SCS, operation conditions, and preoperative preparation of st-SCS, and the prospect of the st-SCS procedure. Initially, the survey was conducted on 110 experts who have practiced the st-SCS procedure from all over the provinces in China. Finally, valuable data was calculated from the 110 questionnaires excluding the doctors with <1 year of experience of st-SCS, <10 cases of procedures per year, and no standard training in SCS technique. Results Based on the 110 questionnaires, it is estimated that 5,000 to 10,000 cases of electrical stimulation are carried out nationwide each year. Sixty-nine valid questionnaires acquired from senior pain physicians were more valuable and specialized in the efficacy, indications, and contraindications of st-SCS for HN. It was commonly agreed (97.10%) that the HN patients with <3 months will obtain good effectiveness (patient satisfaction rate ≥50%). Almost all (98.55%) agreed that st-SCS can be used in SHN patients, there was a common agreement (72.46%) that AHN patients are an indication of st-SCS, and more than half agreement (53.62%) that st-SCS may be fit for early PHN (3–6 months). A common agreement (79.71%) was achieved that more than half of HN patients had the experience of nerve block or nerve pulsed RF. A similarly large number of experts 57/69 (82.61%) agreed that an 80% paresthesia coverage should be achieved at the test stimulation and 57/69 (82.61%) agreed that the treatment of st-SCS need be persistent for 1–2 weeks. Conclusions Early HN patients can get an effective outcome from the treatment of st-SCS and maybe the indication of st-SCS. Moreover, standardized training for pain physicians and basic research and clinical studies are warranted.

Cancer Med 2022; 12:3013-3026. [PMID: 36127838 PMCID: PMC9939124 DOI: 10.1002/cam4.5215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 08/17/2022] [Accepted: 08/24/2022] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Multiple myeloma (MM) is known for its immune disturbance and patients suffering from MM are thus vulnerable to opportunistic infections, including herpes zoster (HZ). As HZ infection remarkably affects patients' quality of life and poses huge economic burdens on the health system, we aim to identify the risk factors of HZ infection and evaluate the effects of different dosages, types, and durations of anti-HZ prophylaxis drugs to prevent HZ infection. METHODS 551 MM patients at Taipei Veterans General Hospital in Taiwan between January 1, 2009 and August 31, 2021 were restrospectively analyzed. The patients' baseline characteristics were recorded. The primary endpoint of the study was the incidence of HZ infection among the studied patient population. Due to the lack of cost coverage from Taiwanese public health insurance on HZ prophylaxis drugs, the use of anti-HZ drugs mainly depends on physicians' preferences and patients' choices. RESULTS In our study, prophylaxis was given to 283 of the patients. In the multivariate analysis, we included non-prophylaxis, age ≥ 60, corrected serum calcium ≥12 mg/dl, serum creatinine ≥2 mg/dl, serum β2-microglobulin ≥5500 mg/L, autologous stem cell transplant (SCT), and allogeneic SCT for analysis. Our results demonstrated that the non-prophylaxis group (HR: 2.37, 95% CI 1.57-3.57) and patients receiving autologous SCT (HR: 2.22, 95% CI 1.28-3.86) and allogeneic SCT (HR: 5.12, 95% CI 1.13-23.22) had higher risk of HZ infection. The difference in dosage and types of anti-HZ drugs showed similar protective effects. In patients who stopped anti-HZ prophylaxis before active cancer-related treatment, a higher risk of getting HZ infection compared to the corresponding group was also observed (adjusted HR 3.09, 95% CI 1.35-7.07, p = 0.008). CONCLUSIONS We concluded that MM patients should receive HZ prophylaxis drugs while receiving active cancer-related treatment. Patients receiving SCT are also at high risk of getting HZ infection, even under prophylaxis.

Abstract
INTRODUCTION The objective was to investigate the risk factors for poor pain control in patients with herpes zoster (HZ)-associated neuropathic pain treated with drugs combined with nerve block therapy. Neuropathic pain commonly follows HZ. Nerve block therapy is the most commonly used clinical treatment for such pain, combining anti-inflammation and analgesia to prevent peripheral sensitization of nerve. METHODS Using clinical practice data from a cohort study at our research center, we established a multivariate logistic regression model to investigate potential risk factors for poor control of zoster-associated pain (ZAP) treated with drugs plus nerve block therapy, including demographic characteristics, complications, laboratory tests, and characteristics of HZ attacks. RESULTS Of the 429 patients with ZAP who received drugs plus nerve block therapy, 95 (22.14%) had poor pain control after treatment. The risk of poor pain control was closely related to presence of cancer (odds ratio (OR) 4.173, 95% confidence interval (CI) 1.342-12.970), numerical rating scale score on admission (OR 1.929, 95% CI 1.528-2.434), and red blood cell count (OR 0.560, 95% CI 0.328-0.954). Area under the receiver operator characteristic curve was 0.730. Goodness of fit (Hosmer-Lemeshow) was 0.874. CONCLUSIONS The risk of poor pain control in patients with ZAP increased as a result of certain patient characteristics and complications, especially severe pain before treatment and cancer.

Abstract
Neuropathic pain is a debilitating symptom reported by patients presenting with postherpetic neuralgia (PHN). Efforts to alleviate this pain have been projected to lie in individualization of pharmacological treatment through pain phenotyping and subsequent investigations into the genetic basis of PHN therapy. Understanding the various mechanisms related to these phenotypes can aid in improvement of available treatment options and discovery of new ones. Knowledge and application of genetic variations in PHN, structural proteins, and genes can aid in ascertaining risk, susceptibility to, severity of, and protection from PHN. This review summarizes the most recent information that has been published on phenotypes and genotypes with possible clinical applications and directions for future research.

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
Varicella-zoster virus (VZV), a highly infectious agent that causes varicella (chickenpox), can also cause zoster (shingles), a disorder that is frequently associated with severe neuralgia. A reliable serological VZV diagnostic assay would be useful for identifying unprotected individuals and for surveilling post-vaccination immunoprotection status. Toward this goal, VZV membrane glycoprotein E (gE), the immunodominant VZV protein, served as target antigen in an indirect ELISA kit developed here to detect anti-VZV antibodies in clinical samples. For target antigen preparation, Chinese hamster ovary (CHO) cells were modified to express and secrete the VZV gE ectodomain, which was subsequently purified and used as coating antigen in an indirect ELISA. Ultimately, the optimal purified gE coating antigen concentration was determined to be 2 μg.ml−1 and the OD450nm detection cutoff value was 0.286. The coefficient of variation (CV) of intra-assay and inter-assay were <10 and 15%, respectively. A comparative test of 66 clinical samples showed that the coincidence rate was 93.9% between the indirect ELISA and a commercial varicella-zoster virus IgG ELISA kit. Thus, the indirect ELISA kit developed here may be useful for achieving rapid, sensitive, and specific detection of anti-VZV antibodies.

[PMID: 35559334 PMCID: PMC9089455 DOI: 10.3389/fmed.2022.850762] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Accepted: 03/18/2022] [Indexed: 12/30/2022] Open
Abstract
Purpose Herpes zoster infection, with its considerable burden to individuals and society, remains a challenge around the world. However, to the knowledge of the authors, little bibliometric quantitative or qualitative analysis has been carried out to evaluate herpes zoster research. This study aimed to use a bibliometric analysis to evaluate current publication trends and hotspots on herpes zoster research worldwide, in order to advance research in this field. Methods Relevant publications from January 2012 to December 2021 were collected from the Web of Science Core Collection database. Citespace (V5.8.R3) was used to analyze the research points, including publication countries, institutions and authors, cited author, cited reference and their clustering, and keyword co-occurrence, and burst keyword to acquire research trends and hotspots. Results A total of 9,259 publications were obtained, with a steady increase in the number of annual publications during the decade. Articles were the main type of publication. The United States is the leading country in this research, and the University of Colorado has the highest influence in this field. Oxman is the most representative author, with a main research interest in herpes zoster vaccines. The top five cited authors' publications focused on herpes zoster vaccines, molecular mechanisms, and postherpetic neuralgia. A co-citation map resulted 19 main clusters, and revealed that vaccines, postherpetic neuralgia, treatments, varicella zoster virus and its mechanisms, and epidemiology of herpes zoster were the current research focus after clustering co-cited publications. Human herpesviruses, antiviral prophylaxis, rheumatoid arthritis, recombinant zoster vaccine, varicella vaccination and postherpetic neuralgia were the top clusters after co-occurrence keywords analysis. Moreover, burst keywords detection showed that the subunit vaccine was the new hotspot in the field of herpes zoster. Conclusion This bibliometric study defined the overall prospects in the field of herpes zoster and provided valuable instruction for the ongoing research. The keyword "subunit vaccine" indicated that a vaccine for herpes zoster prevention was the hotspot. Efforts to prevent varicella zoster virus infection will be essential to improve herpes zoster outcomes.

Cost-Effectiveness Analysis of Herpes Zoster Vaccination in 50- to 85-Year-Old Immunocompetent Belgian Cohorts: A Comparison between No Vaccination, the Adjuvanted Subunit Vaccine, and Live-Attenuated Vaccine. PHARMACOECONOMICS 2022; 40:461-476. [PMID: 35094374 DOI: 10.1007/s40273-021-01099-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 09/30/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND A new adjuvanted subunit vaccine (HZ/su), with higher vaccine efficacy than live-attenuated vaccine (ZVL), has been licensed in Europe since March 2018. Therefore, Belgian decision-makers might need to re-assess their recommendations for vaccination against herpes zoster (HZ). METHODS We conducted a cost-effectiveness analysis, using a Markov decision tree, of vaccinating 50- to 85-year-old immunocompetent Belgian cohorts with no vaccination, HZ/su, ZVL, and ZVL with booster after 10 years. Due to the uncertainty in vaccine waning of HZ/su vaccine beyond 4 years, we used a logarithmic and 1-minus-exponential function to model respectively a long and short duration of protection. We used a lifetime time horizon and implemented the health care payer perspective throughout the analysis. RESULTS HZ/su had the greatest impact in avoiding health and economic burden. However, it would never become cost-effective at a willingness-to-pay threshold of €40,000 per quality-adjusted life year (QALY) gained at its market price set by the manufacturer in the USA. Depending on the waning function assumed for HZ/su, the price per dose needs to drop 60% or 83% such that vaccination with HZ/su, assuming respectively a long or short duration of protection, would become cost-effective in 50- and 80-year-old individuals. At €40,000 per QALY gained, ZVL or ZVL with booster was never found cost-effective compared with HZ/su, even if only administration cost was considered. CONCLUSION HZ/su is cost-effective in the 50-year-old age cohort at the unofficial Belgian threshold of €40,000 per QALY gained, if its price drops to €55.40 per dose. This result is, however, very sensitive to the assumed duration of protection of the vaccine, and the assumed severity and QALY loss associated with HZ and post-herpetic neuralgia (PHN).

Abstract
Herpesviruses can either cause primary infection or may get reactivated after both hematopoietic cell and solid organ transplantations. In general, viral infections increase post-transplant morbidity and mortality. Prophylactic, preemptive, or therapeutically administered antiviral drugs may be associated with serious side effects and may induce viral resistance. Virus-specific T cells represent a valuable addition to antiviral treatment, with high rates of response and minimal side effects. Even low numbers of virus-specific T cells manufactured by direct selection methods can reconstitute virus-specific immunity after transplantation and control viral replication. Virus-specific T cells belong to the advanced therapy medicinal products, and their production is regulated by appropriate legislation; also, strict safety regulations are required to minimize their side effects.

Abstract
Pain, as the most prevalent neurological complication of herpes zoster (HZ), may occur before or during the rash onset or even after the rash has recovered. Particularly, postherpetic neuralgia (PHN) is a refractory chronic condition, usually defined as pain persisting for 3 months or longer from the onset of HZ. Pain evoked by HZ impairs the normal physical and emotional functions of the patients, severely reducing their quality of life. However, how zoster-associated pain occurs and develops into PHN are elusive, making PHN difficult to predict. Uncovering the pathogenesis of zoster-associated pain (or HN) helps us to better understand the onset of PHN and supports developing more effective treatments. In this study, we successfully constructed a model for zoster-associated pain through varicella-zoster virus (VZV) infections of mouse footpads and pain behavior assessments. Next, we used the Kyoto Encyclopedia of Genes and Genomes (KEGG) and the Gene Ontology (GO) to analyze PHN rodent dorsal root ganglion (DRG) gene microarray data and found that calcium signal disorder might be involved in the onset of PHN. By using reverse transcription real-time fluorescent quantitative PCR (RT-qPCR) and Western blotting, we confirmed that VZV infection could significantly upregulate the expression of T-type calcium channel Cav3.2 in DRG and spinal dorsal horn (SDH). Intrathecal administration of Cav3.2 blocker (2R/S)-6-prenylnaringenin (6-PNG) relieved mechanical and thermal hyperalgesia induced by VZV. Taken together, our data indicated that VZV might participate in the occurrence and development of HN by upregulating the expression of Cav3.2 in DRG and SDH. These findings will help to reveal the underlying mechanisms on long-lasting pain and PHN formation, providing a new insight that Cav3.2 can be the promising drug target for remitting PHN.

Abstract
Background and Objectives: This study sought to investigate the natural course, the chronicity and recurrence rate, and the risk factors of chronic and recurrent herpes zoster ophthalmicus (HZO). We also evaluated the effects of long-term treatment for HZO. Materials and Methods: Patients diagnosed and treated for HZO were included in the retrospective medical chart review. Multivariable-adjusted logistic and Cox regression models were used to show risk factors for chronic and recurrent HZO along with hazard ratios (HRs) and 95% confidence intervals (CIs). Results: Among a total 130 of HZO patients, 31 patients (23.85%) had chronic disease and 19 patients (14.62%) had recurrent disease. The rate of chronic disease was higher in HZO with conjunctivitis, epithelial keratitis, and stromal keratitis. The recurrence rate increased in patients with chronic HZO (HR: 34.4, 95% CI: 3.6–324.6), epithelial keratitis (HR: 5.5, 95% CI: 1.3–30.0), stromal keratitis (HR: 18.8, 95% CI: 3.0–120.8), and increased intraocular pressure (IOP) (HR: 7.3, 95% CI: 1.6–33.2). Length of systemic antiviral therapy and anti-inflammatory eyedrop treatment were not associated with recurrent HZO (p = 0.847 and p = 0.660, respectively). The most common ocular manifestation for recurrent HZO was stromal keratitis. Conclusions: This study demonstrated a considerable frequency of chronic and recurrent HZO. Chronic HZO in the form of epithelial or stromal keratitis with increased IOP provoked a significant rise in the risk of recurrence.

Abstract
Neuroimaging studies have displayed aberrant brain activities in individual sensory- and emotional-linked regions in postherpetic neuralgia (PHN) patients. However, multi-dimensional dysfunction in chronic pain may rely on the interplay between networks. Little is known about the changes in the functional architecture of resting state networks (RSNs) in PHN. In this cross-sectional study, we recruited 31 PHN patients, 33 RHZ patients and 34 HCs; all participants underwent resting-state functional magnetic resonance imaging scans. We investigated the differences of within- and cross-network connectivities between different outcomes of HZ patients [including PHN and recuperation from herpes zoster (RHZ)] and healthy controls (HCs) so as to extract a characteristic network pattern of PHN. The abnormal network connectivities were then correlated with clinical variables in respective groups. PHN and RHZ patients could be similarly characterized by abnormal within-default mode network (DMN), DMN-salience network (SN) and SN-basal ganglia network (BGN) connectivity relative to HCs. Of note, compared with RHZ patients, PHN patients could be characterized by abnormal DMN-BGN and within-BGN connectivity. Furthermore, the within-DMN connectivity was associated with pain-induced emotional scores among PHN patients. Our study presented that network-level imbalance could account for the pain-related dysfunctions in different outcomes of herpes zoster patients. These insights are potentially useful for understanding neuromechanism of PHN and providing central therapeutic targets for PHN.

Abstract
Introduction The economic burden of herpes zoster (HZ), including its most common complication, postherpetic neuralgia (PHN), and its impact on health-related quality of life (HRQL) is not well described in Spain. The aim of this study was to estimate HZ-related healthcare costs and impact on HRQL in Spanish adults aged 50 years or older. Methods A prospective, observational study was performed with patients with HZ recruited through four general practitioner networks in Spain (NCT01521286). HRQL data were collected using the EuroQoL-5 Dimension (EQ-5D) questionnaire; HZ-related pain and associated interference with activities of daily living (ADL) were assessed using the Zoster Brief Pain Inventory (ZBPI) questionnaire at days 0 (HZ rash onset), 15, 30, 60, and 90; patients with PHN were assessed up until day 270. Medical resource utilization was recorded throughout study follow-up. Work loss for patients/caregivers was also assessed. Costs were calculated from both the payer and societal perspectives. Results A total of 545 patients with Hz were included, of whom 25 developed PHN. During days 0–30 post HZ diagnosis, the mean EQ-5D utility score was 0.738, equating to a utility loss of 0.138. Sleep was the ADL most affected component. The mean costs for HZ in the overall cohort were €240 and €296 from the payer/societal perspective, respectively; €187/€242 for patients with HZ without any HZ-related complications; and €571/€712 for patients who developed PHN. The majority of costs were incurred during days 0–30. Conclusions In Spain, HZ and HZ-related complications such as PHN reduce patient HRQL and increase the economic burden for both payers and society in general. Trail Registration ClinicalTrials.gov identifier NCT01521286. Supplementary Information The online version contains supplementary material available at 10.1007/s12325-021-01717-7.

Abstract
Shingrix (Recombinant zoster vaccine, RZV) was approved in October 2017 in the United States (US) for the prevention of herpes zoster in adults aged 50 years and older. The vaccine is administered in two doses, with the second dose administration recommended between two and six months after the first dose. Examination of uptake and series completion is important to ensure appropriate use, especially at the time of vaccine introduction. This report provides demographic characteristics of patients receiving RZV between October 2017 and September 2019, first- and second-dose uptake, and a cumulative estimation of second-dose completion by month for US adults aged 50 years and older. Monthly uptake increased rapidly since October 2017; overall, 7,097,441 first doses of RZV were administered along with 4,277,636 second doses during the observed timeframe. Among people with an observed first-dose administration, 70% and 80% completed the two-dose series within six and 12 months post initial dose, respectively. This evidence suggests that RZV has rapidly been adopted by a large population in the US and most are following manufacturer or policy recommendations regarding series completion. Further analyses are needed to explore potential patient, provider, and policy-relevant characteristics associated with second-dose completion that could serve as targets for further improvement.

Abstract
PURPOSE OF REVIEW Chest pain is a very common presenting complaint among patients in the hospital, a large proportion of whom have non-cardiac chest pain (NCCP). Neurological causes of NCCP have not been previously reviewed although several causes have been identified. RECENT FINDINGS Chest pain has been reported as a symptom of multiple neurological conditions such as migraine, epilepsy, and multiple sclerosis, with varying clinical presentations. The affected patients are often not formally diagnosed for long periods of time due to difficulties in recognizing the symptoms as part of neurological disease processes. This paper will briefly summarize well-known etiologies of chest pain and, then, review neurological causes of NCCP, providing an overview of current literature and possible pathophysiologic mechanisms.

Abstract
Background Studies on herpes zoster (HZ) incidence in solid organ transplant (SOT) recipients report widely varying numbers. We investigated HZ incidence, severity, and risk factors in recipients of four different SOTs, with a follow-up time of 6-14 years. Methods Records of 1,033 transplant recipients after first heart (HTx: n = 211), lung (LuTx: n = 121), liver (LiTx: n = 258) and kidney (KTx: n = 443) transplantation between 2000 and 2014 were analyzed for VZV-PCR, clinical signs of HZ, and complications. Results HZ was diagnosed in 108 of 1,033 patients (10.5%): 36 HTx, 17 LuTx, 15 LiTx, and 40 KTx recipients. Overall HZ incidence rate after HTx (30.7 cases/1,000 person-years (PY)), LuTx (38.8 cases/1,000 PY), LiTx (22.7 cases/1,000 PY) and KTx (14.5 cases/1,000 PY) was significantly higher than in the general 50-70 year population. Multivariable analysis demonstrated age ≥50 years at transplantation (p = 0.038, RR 1.536), type of organ transplant (overall p = 0.002; LuTx p = 0.393; RR 1.314; LiTx p = 0.011, RR 0.444; KTx p = 0.034, RR 0.575), CMV prophylaxis (p = 0.043, RR 0.631) and type of anti-rejection therapy (overall p = 0.020; methylprednisolone p = 0.008, RR 0.475; r-ATG p = 0.64, RR1.194) as significant risk factors. Complications occurred in 33 of 108 (31%) patients (39% of HTx, 47% of LuTx, 20% of LiTx, 20% of KTx): post-herpetic neuralgia, disseminated disease, and cranial nerve involvement. Conclusion HZ incidence and severity in SOT recipients are most pronounced after heart and lung transplantation, in older patients, and when CMV prophylaxis is lacking.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of tofacitinib versus other treatment options currently available for the management of adult patients with moderate-to-severe ulcerative colitis, who have had an inadequate response, loss of response, or were intolerant to conventional therapy or a biologic agent, in Greece. METHODS A Markov model was adapted for projecting lifetime costs and outcomes, for a cohort of patients with moderate-to-severe ulcerative colitis from a Greek payer perspective. Patients entered the model in the active ulcerative colitis state and transitioned to a remission or response state or they underwent colectomy. Following an initial 8-week induction treatment period, patients received maintenance therapy until loss of response. Nonresponders could switch to up to two subsequent biologic lines. Clinical efficacy, adverse event rates and utilities derived from OCTAVE trials and a network-meta-analysis (NMA), while adverse event-related disutilities were obtained from the literature. Information on treatment pathways and resource use was provided by an advisory board due to a lack of local data. Unit costs derived from official national sources (€, 2018). RESULTS Over a life-time horizon, treating moderate-to-severe active ulcerative colitis with tofacitinib resulted in additional quality-adjusted life-years (QALYs) and lower total costs compared to vedolizumab (0.018; €6408), infliximab (biosimilar) (0.009; €3031), golimumab (0.042; €1988) and infliximab (originator) (0.009; €6724). Hence, tofacitinib was estimated to be dominant over all comparators. CONCLUSION The results of the analysis suggest that in the Greek setting, tofacitinib could be considered a cost-effective (dominant) treatment option for the treatment of patients with moderate-to-severe active ulcerative colitis.

Abstract
Older adults are at increased risk of herpes zoster (HZ) and post-herpetic neuralgia (PHN) and HZ vaccines are available to help prevent infection. The objective of our study was to provide updated data on incidence of HZ and PHN related to clinical and demographic factors in older adults to inform immunization practices. We conducted a population-based, retrospective cohort study and included all cases of HZ seen in outpatient, emergency department, and hospital settings for adults aged 65 years and over between April 1, 2002 to August 31, 2016 in Ontario, Canada. We calculated the incidence of HZ and PHN, and estimated the proportion within each subgroup that developed PHN. We also assessed incidence by neighbourhood-level income quintile before and after the availability of vaccine for private purchase. The average annual incidence of HZ in any setting was 59.0 per 10,000 older adults, with higher incidence in outpatient as opposed to hospital settings. Incidence was higher in the oldest age groups, females, and those classified as immunocompromised or frail. Relative to the pre-vaccine era, the disparities in incidence of HZ by neighbourhood-level income increased, with higher rates of HZ and PHN seen in those residing in lower income quintiles. Additional prevention efforts should be targeted toward adults who are immunocompromised, frail, and those living in lower socioeconomic quintiles. Future work should assess the impact of the zoster vaccine program with a particular focus on equity in the publicly-funded era.

Abstract
Chronic neuropathic pain (NP) is debilitating and impacts sleep health and quality of life. Treatment with gabapentinoids (GBs) has been shown to reduce pain, but its effects on sleep health have not been systematically evaluated. The objective of this systematic review and meta-analysis was to assess the relationship between GB therapy dose and duration on sleep quality, daytime somnolence, and intensity of pain in patients with NP. Subgroup comparisons were planned for high- vs low-dose GBs, where 300 mg per day or more of pregabalin was used to classify high-dose therapy. Trial data were segregated by duration less than 6 weeks and 6 weeks or greater. Twenty randomized controlled trials were included. Primary outcome measures included pain-related sleep interference and incidence of daytime somnolence. Secondary outcomes included daily pain scores (numerical rating scale 0-10) and patient global impression of change. Significant improvement in sleep quality was observed after 6 weeks of GB treatment when compared with placebo (standardized mean difference 0.39, 95% confidence interval 0.32-0.46 P < 0.001). Increased daytime somnolence was observed among all GB-treated groups when compared with placebo. Treated patients were also more likely to report improvement of patient global impression of change scores. Pain scores decreased significantly in patients both after 6 weeks of treatment (P < 0.001) and in trials less than 6 weeks (P = 0.017) when compared with placebo. Our data demonstrate that GBs have a positive impact on sleep health, quality of life, and pain in patients with NP syndromes. However, these benefits come at the expense of daytime somnolence.

Abstract
OBJECTIVES Tofacitinib is an oral, small molecule Janus kinase (JAK) inhibitor for the treatment of ulcerative colitis (UC). This study assessed the cost-effectiveness of tofacitinib versus other available treatments for patients with moderate to severe UC following an inadequate response to conventional treatment and who are either naïve to or have failed previous biologics in Germany. METHODS A Markov cohort model was developed to evaluate the differences in long-term costs and outcomes between tofacitinib and its comparators from the perspective of German statutory health insurance (SHI) for patients either naïve or exposed to biologics. Tofacitinib was compared to infliximab, infliximab biosimilar, adalimumab, adalimumab biosimilar, golimumab, vedolizumab, ustekinumab, and conventional therapy. Health states modeled were remission, treatment response, active UC, and post-colectomy. Patients not responding to treatment could switch to a different treatment. Treatment efficacy for induction and maintenance phases were assessed by a systematic literature review (SLR) and network meta-analysis (NMA). The model included costs associated with drug administration, adverse events, and medical resource use. Extensive deterministic and probabilistic sensitivity analyses (DSA and PSA) were conducted. RESULTS Over a life-time horizon, patients treated with tofacitinib gained 0.035-0.083 quality-adjusted life-years (QALYs) and had direct cost savings to the SHI of €4,228-€17,184 compared to biologic treatments other than adalimumab biosimilar. When compared to adalimumab biosimilar, treatment with tofacitinib resulted in an incremental cost-effectiveness ratio (ICER) of €17,497 per QALY gained and can be considered a cost-effective alternative. Compared with conventional therapy, tofacitinib resulted in a lower ICER than all other biologics. The DSA showed that the model results were most influenced by differences in treatment efficacy. The PSA suggested confidence in the base-case results considering uncertainty around parameters. CONCLUSIONS The results of this economic model suggest tofacitinib is a cost-effective treatment option for patients with moderate to severe UC in Germany.

Abstract
In recent decades, an increasing number of neuroimaging studies utilizing magnetic resonance imaging (MRI) have explored the differential effects of postherpetic neuralgia (PHN) on brain structure and function. We systematically reviewed and integrated the findings from relevant neuroimaging studies in PHN patients. A total of 15 studies with 16 datasets were ultimately included in the present study, which were categorized by the different neuroimaging modalities. The results revealed that PHN was closely associated with structural/microstructural and functional abnormalities of the brain mainly located in the 'pain matrix', including the thalamus, insula, parahippocampus, amygdala, dorsolateral prefrontal cortex, precentral gyrus and inferior parietal lobe, as well as other regions, such as the precuneus, lentiform nucleus and brainstem. Furthermore, a disruption of multiple networks, including the default-mode network, salience network and limbic system, may contribute to the neurophysiological mechanisms underlying PHN. The findings indicate that the cerebral abnormalities of PHN were not restricted to the pain matrix but extended to other regions, profoundly affecting the regulation and moderation of pain processing in PHN. Future prospective and longitudinal neuroimaging studies with larger samples will elucidate the progressive trajectory of neural changes in the pathophysiological process of PHN.

Abstract
OBJECTIVES Pain and psychological disorders are the 2 most commonly occurring symptom clusters in patients with postherpetic neuralgia (PHN). This study aimed to investigate the risk factors for anxiety and depressive disorders in patients with PHN. METHODS Retrospectively, we examined the potential risk factors of anxiety and depression among patients with PHN from the clinic medical records of the Third Affiliated Hospital of Sun Yat-Sen University from 2017 to 2019. The Chinese version of the Hospital Anxiety and Depression Scale was used to assess anxiety and depression. Patients were retrospectively allocated to 2 groups - PHN with and without anxiety/depression - and compared to identify the differential patient characteristics. RESULTS Cases of 661 patients who were diagnosed with PHN were included. Anxiety and depression developed in 69.0% (456/661) and 65.8% (435/661) of the enrolled patients with PHN, respectively. Results of univariate regression analyses showed that female sex, magnitude of pain intensity, time from onset of rash and extent of spread of rashes were significantly associated with anxiety and depression in patients with PHN. Multivariate analysis revealed that both anxiety and depression states significantly correlated with female sex, magnitude of pain intensity, and extent of spread of rashes. CONCLUSIONS Anxiety and depression were not uncommon in patients with PHN. Women with PHN who experience severe pain and develop extensive rashes have a high risk of developing anxiety and depressive disorders.

Abstract
Background Postherpetic neuralgia (PHN) is the most common complication attributed to herpes zoster, which involves the reactivation of residual varicella zoster virus. It has been reported previously that pre-emptive amitriptyline following acute herpes zoster has shown latent positive effects in the prevention of PHN. In this study, by interfering with the same targets, norepinephrine and serotonin, we aim to evaluate whether pre-emptive duloxetine may proactively prevent PHN development. Methods This is a nationwide multicentric, randomized, open-label, blinded-endpoint study that will recruit 750 participants from 18 primary centres in China. Patients aged more than 50 years who are diagnosed with uncomplicated HZ, present with vesicles within 72 h of their emergence, and have an average pain score of at least 40/100 mm on a visual analogue scale (VAS, 0 mm = no pain, 100 mm = worst possible pain, at opposite ends of a 100-mm line) will be recruited for this study. Participants will be randomized into a duloxetine arm and a control arm. Participants allocated to the duloxetine arm will be given antivirals, analgesics and duloxetine, while those allocated to the control arm will receive antivirals and analgesics but no duloxetine. The primary outcome of this study is preventive efficacy against PHN, which will be evaluated based on a 100 mm VAS. Any pain scores other than 0 mm on the VAS 12 weeks after HZ onset will be defined as PHN. The secondary outcomes will consist of the average weekly VAS score, the average weekly consumption of each analgesic, weekly feature of the pain, patients’ quality of life based on the 12-item Short-Form Health Survey, Patient Global Impression of Change Scale, sleep quality as evaluated by the Pittsburgh Sleep Quality Index and adverse events during the study period. Discussion This study will investigate a prophylactic approach for reducing the prevalence of postherpetic neuralgia with duloxetine and will add significant new knowledge on the preventive effects of duloxetine on PHN. Trial registration Clinicaltrials.gov NCT04313335. Registered on 18 March 2020.

Abstract
Background Estimate the incidence of herpes zoster (HZ), its complications and healthcare utilization rates in adults (≥ 18-years-old) with a wide range of immunocompromised (IC) conditions compared to IC-free cohort. Method A population-based retrospective study using the Valencia healthcare Integrated Databases (VID) (2009–2014). HZ and IC were defined using ICD-9 codes in primary care (PC) and hospitalization registers. Incidence rates (IR), risk of HZ, HZ-recurrence, HZ-complications and healthcare utilization rates were estimated in the IC-cohort compared to IC-free. Results The study population consisted of 4,382,590 subjects, of which 578,873 were IC (13%). IR (in 1000 persons-year) of HZ overall, in IC and in IC-free cohort was 5.02, 9.15 and 4.65, respectively. IR of HZ increased with age in both cohorts and it was higher for all IC conditions studied, reaching up to twelvefold in subjects with stem cell transplantation. IC subjects had 51% higher risk of developing HZ, 25% higher HZ-recurrence and the risk of HZ-complications was 2.37 times higher than in IC-free. HZ-related healthcare utilization was higher in the IC-cohort than in IC-free (number of hospitalizations 2.93 times greater, hospital stays 12% longer, 66% more HZ-specialist visits, 2% more PC visits, sick leaves 18% longer and 20% higher antiviral dispensation). Conclusions Patients suffering from all the IC conditions studied are at higher risk of developing HZ, HZ-recurrence and post-herpetic complications, which implies a substantial morbidity and a high consumption of resources. These results should be considered for vaccine policy implementation.

Abstract
BACKGROUND Postherpetic neuralgia (PHN) is the most common complication and sequela of herpes zoster (HZ) that greatly affects the life and emotional experience of patients. Acupuncture therapy has been confirmed as an effective and safe treatment for PHN. Several systematic reviews (SRs) and meta-analysis (MAs) have reported the evidence of acupuncture therapy for treating PHN. However, the evidence has not been systematically synthesized. This overview aims to synthesize and assess the reliability of evidence generated from these SRs and MAs of acupuncture therapy for PHN. METHODS We will conduct a systematic search of the China Biology Medicine (CBM), VIP database, Wangfang database, China National Knowledge Infrastructure (CNKI), Pubmed, Cochrane Library, Excerpt Medical Database (Embase), and Web of Science to identify eligible SRs and MAs, from their inception to October 31, 2020. We will use Assessment of Multiple Systematic Reviews-2 (AMSTAR2) for methodological quality assessment, Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) for report quality assessment, Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) for the quality of evidence assessment, and ROBIS for the bias assessment. Our reviewers will conduct systematic reviews, qualification evaluation, data extraction, methodological quality, and evidence quality screening in pairs. The outcomes include pain intensity, Quality of life (QoL), Hamilton Anxiety Scale (HAMA), Global impression, and adverse events. All the extracted data will be provided in tabular form to summarize characteristics of each review. The evidence will be a narrative synthesis of the type and content of the intervention and the results reported. RESULTS The results of this study will be published in a peer-reviewed journal. CONCLUSIONS This overview will provide comprehensive evidence of acupuncture therapy for patients with PHN. ETHICS AND DISSEMINATION This review will not involve private information of participants, so the ethical approval will not be required. The results will be disseminated in a peer-reviewed journal or conference presentation. Important protocol modifications will be updated on PROSPERO. PROSPERO REGISTRATION NUMBER CRD42020178738.

Abstract
BACKGROUND/OBJECTIVES Frail participants are often under-represented in randomized trials, raising questions about outcomes of interventions in real-world settings. Frailty is strongly associated with vulnerability to illness and adverse health outcomes. We studied the impact of frailty on recombinant zoster vaccine (RZV) clinical outcomes. DESIGN/SETTING Data from two previously conducted phase III randomized trials of RZV were pooled. These two parent trials were conducted concurrently at the same study sites using the same methods. PARTICIPANTS/INTERVENTION In the two parent studies, participants aged ≥50 years (ZOE-50 study) and ≥70 years (ZOE-70 study), respectively, were randomized 1:1 to receive two doses of RZV or placebo. MEASUREMENTS In the current ZOE-Frailty study (NCT03563183), a frailty index was created using previously validated methods. Clinical outcomes assessed by frailty status included vaccine efficacy, immunogenicity, reactogenicity, and safety. RESULTS Of 29,305 participants from the pooled ZOE-50 and ZOE-70 total vaccinated cohort, 92% were included in this study. Mean age was 68.8 years; 58.1% were women; 45.6% were pre-frail and 11.3% frail. The percentage of frail participants increased with age from 5.7% aged 50-59 years to 22.7% aged ≥80 years. RZV vaccine efficacy against herpes zoster was >90% for all frailty subgroups (non-frail: 95.8% (95% confidence interval = 91.6-98.2), pre-frail: 90.4% (84.4-94.4), frail: 90.2% (75.4-97.0)). The RZV group demonstrated robust anti-gE antibody and gE-specific CD42+ responses, with mean concentrations remaining above pre-vaccination levels at least 3 years post-dose two, in all frailty subgroups. In the RZV group, the percentage of participants reporting solicited adverse events tended to decrease with increasing frailty. CONCLUSION The relatively nonrestrictive inclusion/exclusion criteria in the parent ZOE studies resulted in a range of participants that included frail and pre-frail older adults. RZV significantly reduced the risk of herpes zoster across all frailty subgroups.
