P1160 Real-world comparative safety of filgotinib and upadacitinib for ulcerative colitis: a propensity score matching

Abstract Background We previously reported that upadacitinib (UPA) demonstrated higher effectiveness than filgotinib (FIL) in the treatment of ulcerative colitis (UC) [1]. We aimed to compare safety profiles between FIL and UPA. Methods A multicenter, retrospective observational study was conducted in patients with UC over 18 years old who received FIL or UPA from March 2022 to December 2023 at three territory specialist centres in Japan. The adverse events (AEs) observed in each treatment group were reviewed in detail, and the incidence of AEs was compared using 1:1 propensity score matching (PSM), adjusting for gender, age, disease duration, disease extent, severity (partial Mayo score), previous exposure to biologics or tofacitinib, concomitant medications (5-aminosalicylic acid, immunomodulators, corticosteroids), laboratory data (CRP, Hb, Alb), past medical history, and smoking status. Results A total of 197 patients were enrolled, including 120 patients treated with FIL (median treatment duration 191 days) and 77 with UPA (median treatment duration 154 days). The incidence of AEs was 25.0% (30/120) in the FIL group and 45.5% (35/77) in the UPA group (p<0.01) (Table). The proportion of AEs that resulted in drug discontinuation was 5.0% (6/120) in the FIL groups and 18.2% (14/77) in the UPA group (p<0.01). Only five patients developed herpes zoster (FIL: 3, UPA: 2). No major adverse cardiovascular events, thrombosis or malignancy due to the medication were observed during the study period. At the time of AEs identified, 77.1% of the administered UPA doses were 45 mg. In the PSM approach, a cohort of 55 patients in each group was obtained. After PSM (n=55 each) , the incidence of AEs was 14.6% in the FIL group and 43.6% in the UPA group (risk differnce 29.1, 95% confidence interval [CI]: 13.0-45.2, risk ratio 3.00, 95%CI: 1.48-6.09), which was significantly higher in the UPA group than the FIL group. Conclusion The higher incidence of AEs observed in this study needs to be taken into account when prescribing UPA although it has relatively high efficacy in UC patients.

Herpes zoster prevention in multiple sclerosis and neuromyelitis optica spectrum disorders.

A working group convened by the Section of Multiple Sclerosis and Neuroimmunology of the Polish Neurological Society, the Polish Society of Family Medicine, and the Polish Society of Vaccinology has developed a consensus on supplementary data to the recommendations of the expert group of the Polish Society of Vaccinology, the Polish Society of Family Medicine, the Polish Dermatological Society, the Polish Association for the Study of Pain, and the Polish Neurological Society, and ECTRIMS/EAN of 2023 with regard to the currently available in Poland recombinant herpes zoster vaccine (RZV). It is intended for the prevention of herpes zoster and postherpetic neuralgia in individuals aged > 50 and individuals aged ≥ 18 who belong to herpes zoster risk groups. In Poland it is available with 50% reimbursement exclusively for patients aged 65 and older who have an increased risk of developing herpes zoster. This statement is based on the literature available as of 12 July 2024. The guidance will be updated as new data emerges. All data regarding the above-mentioned vaccine comes from clinical trials which have been reviewed, published and approved by the regulatory authorities and an increasing number of recommendations that might have an impact on real world data.

Association Between Child Varicella Vaccination and Zoster in Household Adults: A Retrospective Japanese Cohort Study.

Some countries are hesitant to implement routine varicella vaccination for children because of concerns over the exogenous boosting hypothesis, which suggests that vaccinating children may increase herpes zoster cases in adults. However, substantial evidence supporting this hypothesis is lacking. This study assessed the association between a child's varicella vaccination status and herpes zoster occurrence in adults in the same household. This retrospective cohort study analysed data from a Japanese city between April 2014 and December 2022. We included individuals aged ≥ 18 years living in households with a single child eligible for varicella vaccination. Children's vaccination status was categorised as unvaccinated, first-dose vaccinated or second-dose vaccinated. Cox regression analysis with time-dependent exposure assessed herpes zoster incidence in adults. Among 4023 eligible individuals, 136 (3.4%) developed herpes zoster over the median follow-up of 552 days. Neither the first nor the second dose of varicella vaccine in children was significantly associated with an increased risk of herpes zoster in adults (hazard ratio 1.24 [95% confidence interval, 0.69-2.23] for the first dose and 1.51 [0.87-2.62] for the second dose). Varicella vaccination in households with a single child was not significantly associated with an increased risk of herpes zoster in adults.

Optimal timing of recombinant herpes zoster virus vaccination for a JAK inhibitor treatment in rheumatoid arthritis: a multicentre, open-label, randomised comparative study (STOP-HZ study): study protocol

IntroductionJanus kinase (JAK) inhibitors are an important therapeutic option in the treatment of rheumatoid arthritis, but increase the risk of developing herpes zoster. Although a dry recombinant zoster vaccine (RZV)...

Organizational barrier to herpes zoster vaccination uptake in Europe: a systematic review

Abstract Background The Herpes Zoster virus represents a significant public health threat for unvaccinated frail individuals and older adults, aged 50 or older. Globally, 95% of elderly and frail individuals are susceptible to develop Herpes Zoster as already being exposed to Varicella Zoster Virus. Organizational and logistical barriers, such as cost management, vaccine storage requirements, supply limitation, logistic difficulties, absence of a streamlined collection system, and healthcare system deficiencies might reduce vaccination uptake. Methods A systematic review was conducted to identify studies published in the last 10 years, and focused on logistic and organizational barriers for Herpes Zoster vaccination uptake among frail and participants aged 50+ in Europe. Prisma guidelines were followed, and AXIS tool was used to evaluate the risk of bias. Results After a thorough analysis, 4 studies were selected from a total of 863 for detailed review. The analysis revealed several barriers to vaccination uptake, including challenges involving healthcare professionals, participant-related obstacles concerning perceptions and knowledge, accessibility issues, structural deficiencies, and social dynamics. A significant barrier identified is the perception among participants that general practitioners either do not support the vaccination or that participants themselves underestimate the risk of developing Herpes Zoster. Additionally, current communication strategies have proven inadequate, indicating a need for more effective and updated approaches to increase public awareness. These factors contribute to hesitancy regarding vaccination. Conclusions This study provides a comprehensive examination of the organizational and logistical barriers to the Herpes Zoster vaccination uptake. Tailored interventions are essential to overcome these barriers. Successfully addressing these challenges might enhance vaccination rate and reduce the public health burden associated with Herpes Zoster. Key messages • Several logistic and organizational barriers reduce the Herpes Zoster vaccination uptake. • Further literature is required to understand how to overcome those barriers, and increase vaccination uptake.

Exploring the association between chronic prostatitis and the risk of herpes zoster in a cohort study in Taiwan.

The aim of the cohort research was to study the association between chronic prostatitis and the probability of herpes zoster in Taiwan. Using the National Health Insurance Research Database (NHIRD) of Taiwan, we selected male persons newly diagnosed with chronic prostatitis aged 20-84 years between 2013 and 2020. These male persons were then matched with a non-prostatitis group who did not have a diagnosis of prostatitis by using 1:1 propensity score matching on age and relevant comorbidities. All participants were observed either until a new diagnosis of herpes zoster was noted or until the completion of the study period in 2020. Cox proportional hazards regression analysis was employed to study the hazard ratio (HR) and 95% confidence interval (CI) for the risk of herpes zoster associated with chronic prostatitis. A total of 69 239 participants with chronic prostatitis and 69 239 participants with non-prostatitis were included in the analysis. The incidence rate of herpes zoster was higher in participants with chronic prostatitis compared to the non-prostatitis group (8.03 per 1000 person-years for chronic prostatitis group versus 4.74 per 1000 person-years for non-prostatitis group, incidence rate ratio = 1.69, and 95%CI = 1.59-1.81). After adjusting for co-variables, participants with chronic prostatitis were found to have a higher risk of developing herpes zoster compared to the non-prostatitis group (adjusted HR = 1.69, 95%CI = 1.59-1.81, and p < 0.001). This cohort research suggests that people with chronic prostatitis may have a greater risk of developing herpes zoster compared to the non-prostatitis group in Taiwan. Preventive strategies, such as the administration of the herpes zoster vaccine, might be beneficial in people with chronic prostatitis.

Herpes zoster in patients with glioma treated with temozolomide

BackgroundThe risk of herpes zoster in patients treated with temozolomide is poorly defined in the literature. We aimed to evaluate the incidence of and risk factors for herpes zoster in individuals receiving temozolomide for glioma. MethodsA retrospective observational study was conducted on a series of patients treated with temozolomide for glioma at a single centre between 1 October 2018 and 30 September 2023. Results131 patients were treated with temozolomide for glioma with a median age of 55 years. 4 out of 131 patients (3.1 %) developed herpes zoster during temozolomide treatment. All cases of herpes zoster occurred in patients who had lymphocyte nadirs of less than 0.7 x 109/L and were receiving corticosteroids concomitantly. The estimated herpes zoster incidence rates were 45.44 per 1000 person-years (95 % confidence interval (CI) 12.38–116.34 per 1000 person-years) in the overall study population and 224.97 per 1000 person-years (95 % CI 61.30–576.02 per 1000 person-years) in subjects who were treated with corticosteroids and had a lymphocyte nadir of less than 1.0 x 109/L. ConclusionUse of temozolomide, particularly in conjunction with lymphopaenia or corticosteroid use, poses a risk of herpes zoster. Further research into the benefits of prophylactic antiviral measures in this population is recommended.

Tofacitinib in Pediatric Alopecia Areata Totalis and Alopecia Universalis: A Retrospective Analysis From India.

Alopecia areata totalis and universalis are disabling conditions and therapeutically challenging as they are refractory to conventional options. Tofacitinib is a Janus-kinase (JAK) inhibitor utilized to treat alopecia areata (AA) as an off-label drug. In India, FDA-approved JAK inhibitors such as baricitinib and ritlecitinib are not available. There are only a few case reports on tofacitinib in AA in the Indian population. We present the data of 9 pediatric cases of clinically and histologically proven alopecia areata totalis (AT) and alopecia universalis (AU), for whom oral tofacitinib was given after baseline investigations. The following parameters were analysed: Photographic image and severity of alopecia tool (SALT) score at baseline, 3 months and 6 months, and Children Dermatology Life Quality Index (cDLQI) at baseline and 6 months. The mean ± standard deviation (M ± SD) of the SALT score and cDLQI(M ± SD) at baseline were 95 ± 5 and 17 ± 2. At weeks 4 and weeks 12, the SALT (M ± SD) score was 92.7 ± 6.1 and 34.35 ± 11.16, respectively. At weeks 24, the SALT (M ± SD) score and cDLQI (M ± SD) were 3.33 ± 5 and 6 ± 2. The final reduction in SALT score from the baseline was 100% in 6/9 cases (66.67%), 75% to 99% in 3/9 (22.23%), and 50 to 75% in 1/9 (11.12%). We also observed minimal adverse effects (one child developed herpes zoster) with tofacitinib. Our study demonstrates that oral tofacitinib represents a viable modality in managing difficult-to-treat pediatric AA, such as AT and AU, with a good safety profile.

Herpes Zoster and Post-Herpetic Neuralgia-Diagnosis, Treatment, and Vaccination Strategies.

Herpes zoster is caused by the reactivation of latent varicella infection within the sensory ganglia, caused by the varicella-zoster virus (VZV). The disease is classically characterized by a painful unilateral vesicular eruption. Complications of the disease include herpes zoster ophthalmicus, Ramsay Hunt syndrome, acute retinal necrosis, and post-herpetic neuralgia. In this paper, we discuss the epidemiology, pathogenesis, clinical features, diagnosis, management, and vaccination strategies of herpes zoster and post-herpetic neuralgia. This paper was developed with input from specialists from Singapore's public sectors-dermatologists, family physicians, and infectious diseases specialists. The diagnosis of herpes zoster is clinical and can be aided with laboratory investigations. Early initiation of antivirals, within 72 h of onset, can reduce the severity and duration of the condition and decrease the intensity of pain. In patients with a high risk of post-herpetic neuralgia, early initiation of anticonvulsants or tricyclic antidepressants can be considered. Herpes zoster is highly preventable, with the advent of the recombinant zoster vaccine (RZV) providing an overall vaccine efficacy of 97.2%. Procedures such as epidural blocks and subcutaneous or intracutaneous injections of local anesthetics and steroids can be considered for patients with a high risk of post-herpetic neuralgia to reduce its incidence. This article serves as a guideline for clinicians in the diagnosis, investigations, management, and prevention of herpes zoster. With the majority of adults in Singapore currently at risk of developing herpes zoster due to varicella immunization being only introduced in 2020, it is important for clinicians to recognize and manage herpes zoster appropriately.

Association Between Coronary Artery Disease and Herpes Zoster: A Cohort Study in Taiwan.

Coronary artery disease (CAD) and herpes zoster represent significant health burdens, and their potential interrelationships remain understudied. This cohort study aimed to address the existing knowledge gap by systematically exploring whether people with CAD are at increased risk for developing herpes zoster. Using the 2006-2015 claims data of the National Health Insurance Program in Taiwan, we identified participants aged ≥20 years with a new diagnosis of CAD as the CAD group. We selected sex- and age-matched participants without CAD as the non-CAD group. The incidence rate of herpes zoster at the end of follow-up was calculated. A multivariable Cox proportional hazards regression model was used to measure the hazard ratio and 95% CI for herpes zoster associated with covariables. The overall incidence rate of herpes zoster was 1.14-fold greater in the CAD group as compared with the non-CAD group (6.52 vs 5.74 per 1000 person-years; 95% CI, 1.08-1.20). After controlling for covariables, the adjusted hazard ratio of herpes zoster was 1.21 (95% CI, 1.14-1.27) for the CAD group as compared with the non-CAD group. This cohort study provides valuable insights into the potential association between CAD and the risk of developing herpes zoster. The findings may have implications for preventive strategies of herpes zoster in people with CAD. Further research and collaboration with diverse groups will be critical to validate and extend our findings.

A Case of Herpes Zoster Simulating Pemphigus Vulgaris Flare

Pemphigus vulgaris is an autoimmune bullous disorder caused by autoantibodies directed against desmogleins. There is an increased risk for developing herpes zoster in pemphigus vulgaris due to the prolonged and high doses immunosuppressant therapy. Here, we present a 52-year-old female patient with extensive pemphigus vulgaris who developed herpes zoster while on treatment which resulted in a diagnostic confusion and a Tzanck smear acted as a lifesaver revealing both multinucleated giant cells and acantholytic cells. Hence, a prompt decision of reducing the immunosuppressant and initiation of IV acyclovir helped the patient to recover faster. This case highlights the relevance of simple bedside investigation like Tzanck smear and reminds the clinician once again to be open to all possibilities.

Efficacy and safety of filgotinib for ulcerative colitis: A real-world multicenter retrospective study in Japan.

While filgotinib, an oral Janus kinase (JAK) 1 preferential inhibitor, is approved for moderately to severely active ulcerative colitis (UC), real-world studies assessing its short- and long-term efficacy and safety are limited. This is a multicenter, retrospective study of UC patients who started filgotinib between March 2022 and September 2023. The primary outcome was clinical remission, defined as a partial Mayo score ≤1 with a rectal bleeding score of 0, or Simple Clinical Colitis Activity Index (SCCAI) ≤2 with a blood-in-stool score of 0. Secondary outcomes included clinical response, corticosteroid-free remission, and endoscopic improvement. Outcomes were assessed at 10, 26, and 58 weeks based on patients with available follow-up. Adverse events were evaluated. We identified 238 UC patients and 54% had prior exposure to biologics/JAK inhibitors. The median baseline partial Mayo score and SCCAI were 5 (IQR 3-6) and 4 (IQR 2-7). Clinical remission rates based on per-protocol analysis at 10, 26, and 58 weeks were 47% (70/149), 55.8% (48/86), and 64.6% (31/48), respectively. At a median follow-up of 28 weeks (IQR 10-54) with a discontinuation rate of 39%, the rates of clinical remission, clinical response, corticosteroid-free remission, and endoscopic improvement were 39.9% (81/203), 54.7% (111/203), and 36.5% (74/203), and 43.5% (10/23), respectively. These rates were comparable between biologic/JAK inhibitor-naïve and -experienced patients. While three patients (1.3%) developed herpes zoster infection, no cases of thrombosis or death were reported. Real-world data demonstrate favourable clinical and safety outcomes of filgotinib for UC.

Risk Factors and the Effect of Antiviral Prophylaxis for Herpes Zoster in Multiple Myeloma Patients

To study the incidence and risk factors of herpes zoster in patients with multiple myeloma and to evaluate the preventive effect of antiviral therapy. The clinical features of multiple myeloma patients with herpes zoster were retrospectively analyzed, the risk factors of herpes zoster and the effect of antiviral prophylaxis were analyzed. Among 180 patients with multiple myeloma, 23 cases developed herpes zoster (12.8%). The incidence of herpes zoster was 19.1% in patients with renal dysfunction and 23.5% after autologous hematopoietic stem cell transplantation (ASCT). The incidence of herpes zoster was higher in patients receiving bortezomib-containing regimens (21/137, 15.3%) than that in those without bortezomib (2/43, 4.7%), but there was no statistical difference (P =0.067). Antiviral prophylaxis was associated with fewer zoster infections, 8/111(7.2%) developed herpes zoster in patients who received antiviral prophylaxis, and 15/69 (21.7%) in those receiving no prophylaxis(P =0.005). 65.2% of patients with herpes zoster did not receive antiviral prophylaxis. Multivariate analysis showed that bortezomib treatment, AHSCT and renal dysfunction were independent risk factors for multiple myeloma with herpes zoster, while antiviral prophylaxis was independently associated with reducing the risk of herpes zoster. Herpes zoster had no effect on OS in patients with multiple myeloma. The risk of herpes zoster in multiple myeloma patients was increased. Antiviral prophylaxis can reduce the risk of herpes zoster in patients on bortezomib-based therapy.

Delayed Superior Orbital Fissure Syndrome Arising More than One Month after Herpes Zoster Ophthalmicus and Meningitis.

A 79-year-old woman developed herpes zoster ophthalmicus (HZO) with a vesicular rash on the nasal root, which developed soon after intravenous acyclovir therapy. Although varicella zoster virus DNA was undetectable in the cerebrospinal fluid, she presented with ophthalmoplegia without optic nerve dysfunction 32 days after the onset of HZO. We diagnosed the patient with superior orbital fissure syndrome and administered intravenous immunoglobulin and systemic corticosteroids. Ophthalmoplegia did not immediately respond to these therapies but resolved 4 months later. We should be aware that ophthalmoplegia can occur, even after HZO and meningitis are completely treated.

Biologics Therapy in Paediatric Rheumatic Diseases in Hong Kong

Background: There is a substantial expansion in the number of biologics available for the treatment of JIA and childhood rheumatic disease over the past decades. However, there is no report on their use and safety profile in the local paediatric population. Method of study: This is a multi-centred retrospective cohort study, recruiting patients followed up in three Paediatric departments in Hong Kong. Subjects who were followed up for childhood-onset rheumatic diseases and was treated with any of the biologic DMARs on or before the 31st December 2022, were reviewed. Results: A total of 96 patients who received biologic DMARs in the studied period were reviewed. Sixty patients were diagnosed to have JIA, cSLE (10), uveitis (8), refractory KD (7), JDM (2), COVID-MISC (3), and others (6). Concerning the JIA group, male: female is 1.4:1. 38% of the patients had polyarticular JIA and 50% had ERA who failed conventional treatment with various cDMARS. Concerning the nature of biologics, 85% of JIA patients used different types of TNF-blockers, including etanercept (38.3%), adalimumab (40%), golimumab (5%) and infliximab (3.3%). Six JIA patients used tocilizumab and one used abatacept as second-line treatment after fail response to TNF-blockers. One JIA patient was on tofacitinib to avoid subcutaneous injection. For other biologics, infliximab for refractory KD (8), rituximab for cSLE and JDM (7 and 1), belimumab in cSLE (2) and anakinra in COVID-MISC (4). One JIA-ERA patient developed lymphoma six months after stopping adalimumab and recovered after chemotherapy. One cSLE patient received rituximab and developed EBV-related CNS lymphoma with repeated infections that required hospitalization. Most patients tolerated the biologic DMARs well without complications. There was no tuberculosis infection or activation. Two cSLE patients developed herpes zoster after rituximab infusion and required hospital treatment. Two patients on adalimumab developed recurrent folliculitis and one had to stop treatment. One patient developed bacteria endophthalmitis while on adalimumab. Four patients on adalimumab developed injection site reactions and one patient need to change to another biologic. One patient on adalimumab developed positive lupus serology without clinical features. Conclusion: A broad spectrum of biologics has been used in children with various rheumatic diseases without major complications. Although rare, 2 patients developed lymphoma during the study period. Although there is no causal relationship identified with the use of biologics, continuous monitoring of the long-term safety of these drugs in the paediatric cohort is recommended.

Impact of Type 1 Versus Type 2 Diabetes on Developing Herpes Zoster and Post-herpetic Neuralgia: A Population-based Cohort Study.

Type 2 diabetes is associated with an increased risk of herpes zoster and postherpetic neuralgia. However, the association of type 1 diabetes with herpes zoster or postherpetic neuralgia remains unclear. This retrospective cohort study using Taiwan's Health Insurance Research Database included 199,566 patients with type 1 diabetes and 1,458,331 with type 2 diabetes, identified during the period 2000 to 2012. Patients with type 1 diabetes had a significantly higher risk of developing herpes zoster than those with type 2 diabetes (p < 0.001). Across all age groups, the impact of diabetes on herpes zoster was greater in type 1 than in type 2 diabetes. Patients with both type 1 and type 2 diabetes had a 1.45-fold higher risk of post-herpetic neuralgia than those without diabetes (hazard ratio 1.45, 95% confidence interval 1.28-1.65; hazard ratio 1.45, 95% confidence interval 1.37-1.52, respectively), and there was no difference between the 2 types of diabetes (hazard ratio 1.06; 95% confidence interval 0.93-1.21). The results recommend consideration of herpes zoster vaccination at an earlier age in patients with type 1 diabetes.

Tofacitinib Versus Oral Prednisolone for Induction of Remission in Moderately Active Ulcerative Colitis [ORCHID]: A Prospective, Open-Label, Randomized, Pilot Study.

Oral corticosteroids are first-line agents to induce remission in moderately active ulcerative colitis [UC], but are associated with adverse effects. We compared the efficacy and safety of tofacitinib and prednisolone for induction of remission in moderately active UC. This was a single-centre, prospective, open-label, randomized, active-controlled pilot study. Eligible patients [aged ≥18 years] had moderately active UC. Participants were randomly assigned to receive either prednisolone [40 mg daily, tapered by 5 mg every week] or tofacitinib [10 mg twice daily] for 8 weeks. The primary endpoint was composite remission [defined as total Mayo clinic score ≤2, with endoscopic sub-score of 0 and faecal calprotectin <100 µg/g] at 8 weeks. Seventy-eight patients were randomly assigned to either of the treatment groups. At week 8, the proportion of patients achieving composite remission in the tofacitinib [7/43, 16.28%] and prednisolone groups [3/35, 8.57%] were not significantly different (odds ratio [OR] 2.07, 95% confidence interval [CI] 0.49-8.70; p = 0.31). The time to achieve symptomatic remission [normal stool frequency with absence of rectal bleeding] was similar (10 days, interquartile range [IQR 7-18.75] and 10 days [IQR 5-12.5] for tofacitinib and prednisolone, respectively; p = 0.25) in the two groups. One patient each in the tofacitinib and prednisolone group discontinued treatment due to development of pulmonary tuberculosis and pustular acne, respectively. One patient receiving tofacitinib developed herpes zoster, but did not require cessation of therapy. No serious adverse events or major adverse cardiovascular events were observed. In patients with moderately active UC, there was no difference in the efficacy and safety of tofacitinib and oral prednisolone for induction of remission at 8 weeks.

Efficacy of JAK Inhibitors versus DMARDs in the Treatment of Polymyalgia Rheumatica in China.

This retrospective analysis was to assess the role of Janus kinases (JAK) inhibitors compared with conventional disease modifying anti-rheumatic drugs (DMRADs) in the treatment of polymyalgia rheumatica (PMR) with glucocorticoids (GCs) reduction. Clinical information was collected from PMR patients in the JAK inhibitor group and the DMARDs group from January 2020 to August 2021 at Jiaxing first Hospital. Serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), hemoglobin (Hb), albumin and dose of GCs before and after treatment were compared between two groups. Thirty female patients with PMR were included into this study. The dose of GCs in the JAK inhibitor group was significantly lower than in the DMARDs group at baseline and at 3 and 6 months after treatment. There were no significant differences in various laboratory parameters (including CRP, ESR, Hb and albumin) between two groups (P > 0.05) except that Hb in the DMARDs group was significantly higher than in the JAK inhibitor group at 3 and 6 months after treatment (P<0.05). One patient in the JAK inhibitor group developed herpes zoster, and received tofacitinib treatment after herpes zoster was relieved. Our study indicates that JAK inhibitors in the treatment of PMR are as effective as DMRADs and are also helpful for the reduction of GCs dose.

Risk of herpes zoster according to past history in the general population: The Japanese Shozu herpes zoster study.

Immunity is known to persist after vaccination for varicella zoster virus, but the duration of immunity in patients who develop herpes zoster (HZ) remains unknown. To investigate the association between a past history of HZ and its occurrence in the general population. The Shozu HZ (SHEZ) cohort study included data for 12 299 individuals aged ≥50 years with information on their HZ history. Cross-sectional and 3-year follow-up studies were carried out to analyze the associations between a history of HZ (yes <10 years, yes ≥10 years, no) and the proportion of positive varicella zoster virus skin test results (erythema diameter ≥5 mm) and the risk of HZ after adjusting for potential confounding factors including age, sex, body mass index, smoking status, sleep duration, and mental stress. The incidences of positive skin test results were 87.7% (470/536) for individuals with a history of HZ <10 years ago, 82.2% (396/482) for those with a history of HZ ≥10 years, and 80.2% (3614/4509) for those with no history of HZ. The multivariable odds ratios (95% confidence intervals) of erythema diameter ≥5 mm were 2.07 (1.57-2.73) and 1. 39 (1.08-1.80) for individuals with a history <10 years and ≥10 years ago, respectively, compared with no history. The corresponding multivariable hazard ratios of HZ were 0.54 (0.34-0.85) and 1.16 (0.83-1.61), respectively. A past history of HZ <10 years ago may reduce the occurrence of HZ.

Case report: Relapsed disseminated cutaneous herpes zoster successfully treated with brivudine

A 64-year-old man presented with painful rash on the trunk and extremities for more than half a month. Nephrotic syndrome had been diagnosed 2 years ago and had been regularly treated with glucocorticoids and immunosuppressants. He developed herpes zoster 1 year ago. Laboratory investigation demonstrated varicella-zoster virus DNA (VZV-DNA), varicella-zoster virus IgM (VZV-IgM), and varicella-zoster virus antibody IgG (VZV-IgG) were all positive. After the clinical diagnosis of relapsed disseminated cutaneous herpes zoster had been confirmed, systemic therapy with brivudine 125 mg everyday was started.
