Effect of high dose vitamin D supplementation on subsequent immune responses to administration of the live herpes zoster vaccine to long-term care residents.

Thirty-three long-term care residents (mean age 76.5 years), who were participating in a study in which they were randomized to receive either oral daily standard dose (400-1000 IU/day) 25-hydroxy vitamin D (vitamin D3) (SD) or high dose (3000-4000 IU/day) (HD) vitamin D3, were vaccinated with the live, attenuated herpes zoster vaccine. Blood was drawn at vaccination and three weeks later to determine varicella-zoster virus (VZV) antibody and T-cell mediated immune responses. ELISA and neutralizing antibodies increased significantly, but to the same extent, in both groups. The antibody avidity significantly increased from pre- to post-vaccination only in the HD group. VZV-CMI, as measured by FLUOROSPOT significantly increased post-vaccination in both groups, but the difference in interferon-γ spot-forming cells (SFC) and interleukin-2 SFC was lower in the HD than SD group. The increase in VZV-CMI correlated inversely with circulating regulatory T cells in the HD group. We conclude that pre-treatment with HD vitamin D3 does not appreciably enhance the antibody response to a live vaccine and that VZV-CMI responses were diminished in HD vitamin D3 recipients.

Crohn's Disease and Herpes Zoster: Being Mindful of Vaccination.

Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract. Immunosuppressive therapy is the main treatment modality in Crohn's disease. Herpes zoster (HZ), caused by Varicella-zoster virus, is a relatively common albeit burdensome clinical picture mainly affecting adult population with immunosuppressive status. In this paper, we aimed to report a Crohn's disease patient with HZ to raise awareness on vaccination. There are commercially available vaccines that are shown to be safe and effective against HZ reactivation. Crohn's disease patients should be evaluated and informed about preventive options against HZ to prevent unwanted HZ-related complications.

Effectiveness of the live zoster vaccine during the 10 years following vaccination: real world cohort study using electronic health records.

OBJECTIVES: To assess the effectiveness of live zoster vaccine during more than 10 years after vaccination; and to describe methods for ascertaining vaccine effectiveness in the context of waning. DESIGN: Real world cohort study using electronic health records. SETTING: Kaiser Permanente Northern California, an integrated healthcare delivery system in the US, 1 January 2007 to 31 December 2018. POPULATION: More than 1.5 million people aged 50 years and older followed for almost 9.4 million person years. MAIN OUTCOME MEASURE: Vaccine effectiveness in preventing herpes zoster, postherpetic neuralgia, herpes zoster ophthalmicus, and admission to hospital for herpes zoster was assessed. Change in vaccine effectiveness by time since vaccination was examined using Cox regression with a calendar timeline. Time varying indicators were specified for each interval of time since vaccination (30 days to less than one year, one to less than two years, etc) and adjusted for covariates. RESULTS: Of 1 505 647 people, 507 444 (34%) were vaccinated with live zoster vaccine. Among 75 135 incident herpes zoster cases, 4982 (7%) developed postherpetic neuralgia, 4439 (6%) had herpes zoster ophthalmicus, and 556 (0.7%) were admitted to hospital for herpes zoster. For each outcome, vaccine effectiveness was highest in the first year after vaccination and decreased substantially over time. Against herpes zoster, vaccine effectiveness waned from 67% (95% confidence interval 65% to 69%) in the first year to 15% (5% to 24%) after 10 years. Against postherpetic neuralgia, vaccine effectiveness waned from 83% (78% to 87%) to 41% (17% to 59%) after 10 years. Against herpes zoster ophthalmicus, vaccine effectiveness waned from 71% (63% to 76%) to 29% (18% to 39%) during five to less than eight years. Against admission to hospital for herpes zoster, vaccine effectiveness waned from 90% (67% to 97%) to 53% (25% to 70%) during five to less than eight years. Across all follow-up time, overall vaccine effectiveness was 46% (45% to 47%) against herpes zoster, 62% (59% to 65%) against postherpetic neuralgia, 45% (40% to 49%) against herpes zoster ophthalmicus, and 66% (55% to 74%) against admission to hospital for herpes zoster. CONCLUSIONS: Live zoster vaccine was effective initially. Vaccine effectiveness waned substantially yet some protection remained 10 years after vaccination. After 10 years, protection was low against herpes zoster but higher against postherpetic neuralgia. TRIAL REGISTRATION: ClinicalTrials.gov number NCT01600079; EU PAS register number EUPAS17502.

Longdan Xiegan formula as adjuvant therapy for acute herpes zoster: A meta-analysis of randomized controlled trials.

Longdan Xiegan (LDXG) decoction, an ancient Chinese herbal formula, has been widely used in treating herpes zoster. This meta-analysis aimed to evaluate whether LDXG formula as adjuvant therapy had additional benefits in acute herpes zoster patients. Two authors independently searched PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wanfang database from their inception to July 31, 2021. Relevant randomized controlled trials (RCTs) that investigated the add-on effects of LDXG formula (decoction, capsule, or pill) in the management of acute herpes zoster were included. Nine RCTs with 821 patients were identified. A random effect model meta-analyses showed that LDXG formula plus conventional therapy significantly reduced the time to blister resolution (weighted mean difference [WMD] -1.31 days; 95% confidence intervals [CI] -1.56 to -1.06), time to crust formation (WMD -1.91 days; 95% CI -2.31 to -1.50), time to pain resolution (WMD -2.13 days; 95% CI -2.65 to -1.60), pain intensity assessed by visual analogue scale (WMD -1.13; 95% CI -2.03 to -0.24), and incidence of persistent pain (risk ratio [RR] 0.28; 95% CI 0.15-0.50) compared with the conventional therapy alone. However, the overall certainty of evidence was very low to moderate. LDXG formula as adjuvant therapy may achieve additional benefits in terms of accelerating skin healing process, relieving pain symptoms, and preventing persistent pain in acute herpes zoster patients. However, interpretation of these findings should be considered the presence of statistical heterogeneity and/or unclear risk of bias.

Association between vitamin D and incident herpes zoster: a UK Biobank study.

BACKGROUND: Vitamin D has immunomodulatory effects, but any association with herpes zoster (HZ) is unclear. AIM: To explore the association between vitamin D status and risk of incident HZ in adults in the UK. DESIGN AND SETTING: A cohort study involving participants of UK Biobank (a database containing the health information from half a million individuals) across England, Wales, and Scotland, who had at least one vitamin D testing result with linked primary care electronic health records. METHOD: The primary exposure was vitamin D status, categorised as deficient (<25 nmol/L), insufficient (25-49 nmol/L), or sufficient (≥50 nmol/L). The secondary exposures were self-reported vitamin D supplementation at baseline assessment and vitamin D prescription records. The outcome was diagnosed incident HZ, identified from linked primary care or hospital inpatient records. Weibull regression was used, adjusting for potential confounders, including demographic factors, comorbidities, and immunosuppression. RESULTS: In total, 177 572 eligible participants were included in the analysis, with a mean follow-up time of 10.1 years (standard deviation 1.9 years). No evidence showed that low vitamin D was associated with a higher incidence of HZ, compared with people with sufficient vitamin D (deficient: adjusted hazard ratio [HR] 0.99, 95% confidence interval [CI] = 0.90 to 1.10; insufficient: HR 1.03, 95% CI = 0.96 to 1.10). No evidence was found that supplementing vitamin D or receiving vitamin D prescription was associated with HZ incidence (supplementation: HR 0.88, 95% CI = 0.67 to 1.16; prescription: HR 1.11, 95% CI = 0.91 to 1.34). CONCLUSION: No association of vitamin D status, supplementation, or prescription with incident HZ was observed. No evidence supported vitamin D supplementation as a strategy to prevent HZ.

Identification of novel potential inhibitors of varicella-zoster virus thymidine kinase from ethnopharmacologic relevant plants through an in-silico approach.

Although Varicella or chickenpox infection which is caused by the varicella-zoster virus (VZV) has significantly been managed through vaccination, it remains an infection that poses threats to the nearest future due to therapeutic drawbacks. The focus of this research was geared towards in silico screening for the identification of novel compounds in plants of ethnopharmacological relevance in the treatment of chicken pox in West Africa. The work evaluated 65 compounds reported to be present in Achillea millefolium, Psidium guajava and Vitex doniana sweet to identify potential inhibitors of thymidine kinase, the primary drug target of varicella zoster virus. Out of the 65 compounds docked, 42 of these compounds were observed to possess binding energies lower than -7.0 kcal/mol, however only 20 were observed to form hydrogen bond interactions with the protein. These interactions were elucidated using LigPlot+ and MM-PBSA analysis with residue Ala134 predicted as critical for binding. Pharmacological profiling predicted three potential lead compounds comprising myricetin, apigenin- 4' -glucoside and Abyssinone V to possess good pharmacodynamics properties and negligibly toxic. The molecules were predicted as antivirals including anti-herpes and involved in mechanisms comprising inhibition of polymerase, ATPase and membrane integrity, which were corroborated previously in other viruses. These drug-like compounds are plausible biotherapeutic moieties for further biochemical and cell-based assaying to discover their potential for use against chickenpox. Communicated by Ramaswamy H.

Importance of Compliance With Guidelines for the Prevention of Varicella-Zoster Virus Reactivation in Multiple Myeloma.

BACKGROUND/AIM: The importance of compliance with National Comprehensive Cancer Network (NCCN) guidelines for preventing varicella-zoster virus reactivation (VZVr) in multiple myeloma (MM) in a clinical setting has not been well investigated. PATIENTS AND METHODS: We retrospectively studied the clinical characteristics and outcomes of 118 patients with MM treated with proteasome inhibitors. RESULTS: Thirty-nine episodes of VZVr were observed in 37 patients (VZVr group). The proportion of prophylactic antiviral prescriptions and compliance with antiviral prophylaxis based on the NCCN Clinical Practice guidelines was 76% and 30% in the VZVr group, and 88% and 74% in the non-VZVr group, respectively. Multivariate analysis showed that compliance with the NCCN guidelines was the only independent risk factor for VZVr (p=0.0017). CONCLUSION: It is important that prophylactic antivirals are prescribed for an appropriate duration of time to prevent the reactivation of VZV in compliance with existing guidelines.

Safety, tolerability of ES16001, a novel varicella zoster virus reactivation inhibitor, in healthy adults.

PURPOSE: Herpes zoster (HZ), or shingles, is a clinical syndrome resulting from the reactivation of latent varicella zoster virus (VZV) within the sensory ganglia. We evaluated the safety and tolerability of ES16001 (ethanol extract of Elaeocarpus sylvestris var. ellipticus), a novel inhibitor of varicella zoster virus reactivation in healthy adults. METHOD: Single-center, randomized, double-blind, placebo-controlled, single and multiple ascending dose (SAD and MAD, respectively) studies were conducted in 20- to 45-year-old healthy adults without chronic disease. In the SAD study (n = 32), subjects randomly received a single oral dose of 240, 480, 960, or 1440 mg ES16001 or a placebo. In the MAD study (n = 16), subjects randomly received once daily doses of 480 or 960 mg ES16001 or a placebo for 5 days. The safety and tolerability of the drug were evaluated by monitoring participants' treatment emergent adverse events (TEAEs) and vital signs, electrocardiograms (ECGs), physical examinations, and clinical laboratory tests. RESULTS: In the SAD study, 11 adverse reactions were seen in 5 subjects, and in the MAD study, 8 adverse reactions were seen in 6 subjects. All adverse reactions were mild, and no serious adverse reactions occurred. The most common adverse reaction was an increase in alanine aminotransferase (ALT), but all test values were in the clinically non-significant range, and their clinical significance was judged to be small considering the fact that most of the test values returned to normal immediately after the end of drug administration. CONCLUSION: ES16001 has good safety and tolerability when administered both once and repeatedly to healthy subjects. Further research is needed to identify any possible drug-induced hepatotoxicity, which appears infrequently. Our findings provide a rationale for further clinical investigations of ES16001 for the prevention of HZ. TRIAL REGISTRATION: CRIS, KCT0006066.

Cost-effectiveness of varicella and herpes zoster vaccination in Sweden: An economic evaluation using a dynamic transmission model.

OBJECTIVES: Comprehensive cost-effectiveness analyses of introducing varicella and/or herpes zoster vaccination in the Swedish national vaccination programme. DESIGN: Cost-effectiveness analyses based on epidemiological results from a specifically developed transmission model. SETTING: National vaccination programme in Sweden, over an 85- or 20-year time horizon depending on the vaccination strategy. PARTICIPANTS: Hypothetical cohorts of people aged 12 months and 65-years at baseline. INTERVENTIONS: Four alternative vaccination strategies; 1, not to vaccinate; 2, varicella vaccination with one dose of the live attenuated vaccine at age 12 months and a second dose at age 18 months; 3, herpes zoster vaccination with one dose of the live attenuated vaccine at 65 years of age; and 4, both vaccine against varicella and herpes zoster with the before-mentioned strategies. MAIN OUTCOME MEASURES: Accumulated cost and quality-adjusted life years (QALY) for each strategy, and incremental cost-effectiveness ratios (ICER). RESULTS: It would be cost-effective to vaccinate against varicella (dominant), but not to vaccinate against herpes zoster (ICER of EUR 200,000), assuming a cost-effectiveness threshold of EUR 50,000 per QALY. The incremental analysis between varicella vaccination only and the combined programme results in a cost per gained QALY of almost EUR 1.6 million. CONCLUSIONS: The results from this study are central components for policy-relevant decision-making, and suggest that it was cost-effective to introduce varicella vaccination in Sweden, whereas herpes zoster vaccination with the live attenuated vaccine for the elderly was not cost-effective-the health effects of the latter vaccination cannot be considered reasonable in relation to its costs. Future observational and surveillance studies are needed to make reasonable predictions on how boosting affects the herpes zoster incidence in the population, and thus the cost-effectiveness of a vaccination programme against varicella. Also, the link between herpes zoster and sequelae need to be studied in more detail to include it suitably in health economic evaluations.

Risk of infection associated with Janus Kinase (JAK) inhibitors and biological therapies in inflammatory intestinal disease and rheumatoid arthritis. Prevention strategies. / Riesgo de infección asociado a los inhibidores de las quinasas Janus (JAK) y las terapias biológicas en enfermedad inflamatoria intestinal y artritis reumatoide. Estrategias de prevención.

Patients with certain immune-mediated inflammatory diseases, such as rheumatoid arthritis (RA) and inflammatory bowel disease (IBD), have an increased risk of severe infectious diseases than the general population, which are mainly associated with the immunosuppressive treatments that they receive. These treatments act on the immune system through different mechanisms, causing different degrees of immunosuppression and a variable risk depending on whether the pathogen is a virus, bacteria or fungus. This article reviews the most relevant literature on the subject, which was selected and discussed by a panel of experts. The aim of this article is to review the risk of infections in patients with IBD and RA, and the potential preventive measures.

Incidence of herpes zoster among varicella-vaccinated children, by number of vaccine doses and simultaneous administration of measles, mumps, and rubella vaccine.

INTRODUCTION: Children may receive measles-mumps-rubella (MMR) and varicella (VAR) vaccines separately or as measles-mumps-rubella-varicella (MMRV). We examined whether pediatric herpes zoster (HZ) incidence varied by pattern of varicella vaccine administration. METHODS: In six integrated health systems, we examined HZ incidence among children turning 12 months old during 2003-2008. All received varicella and MMR vaccines on recommended schedules. Cases were identified through 2014 using ICD-9 codes. Incidence was examined by number of varicella vaccine doses and same-day MMR. RESULTS: Among 199,797 children, overall HZ incidence was 18.6/100,000 person-years in the first-dose MMR + VAR group, 17.9/100,000 person-years in the MMRV group, and 7.5/100,000 person-years in the VAR-alone group. HZ incidence was lower following the second dose than before the second dose in all first-dose groups. CONCLUSIONS: HZ incidence was not meaningfully different between the MMRV and MMR + VAR first-dose groups. Overall and within first-dose groups, HZ incidence was lower among children receiving two varicella vaccine doses.

Incidence of Herpes Zoster Among Children: 2003-2014.

BACKGROUND AND OBJECTIVES: After the 1996 introduction of routine varicella vaccination in the United States, most studies evaluating pediatric herpes zoster (HZ) incidence reported lower incidence over time, with varying degrees of decline. Using the combined databases of 6 integrated health care organizations, we examined HZ incidence in children over a 12-year period in the varicella vaccine era. METHODS: This study included children aged 0 through 17 years from 2003 through 2014. Using electronic medical records, we identified HZ cases through International Classification of Diseases, Ninth Revision diagnosis code 053. We calculated HZ incidence rates per 100 000 person years of health plan membership for all children and among children who were vaccinated versus unvaccinated. We calculated rates for the 12-year period and examined temporal trends. Among children who were vaccinated, we compared HZ rates by month and year of age at vaccination. RESULTS: The study included 6 372 067 children with ≥1 month of health plan membership. For the 12-year period, the crude HZ incidence rate for all subjects was 74 per 100 000 person years, and the rate among children who were vaccinated was 38 per 100 000 person years, which was 78% lower than that among children who were unvaccinated (170 per 100 000 person years; P < .0001). Overall HZ incidence declined by 72% (P < .0001) from 2003 through 2014. Annual rates in children who were vaccinated were consistently lower than in children who were unvaccinated. CONCLUSIONS: With this population-based study, we confirm the decline in pediatric HZ incidence and the significantly lower incidence among children who are vaccinated, reinforcing the benefit of routine varicella vaccination to prevent pediatric HZ.

Correlates of adjuvanticity: A review on adjuvants in licensed vaccines.

After decades of slow progress, the last years have seen a rapid acceleration of the development of adjuvanted vaccines which have lately been approved for human use. These adjuvants consist of different components, e.g. aluminium salts, emulsions such as MF59 and AS03, Toll-like receptor (TLR) agonists (CpG ormonophosphoryl lipid A (MPL) adsorbed on aluminium salts as in AS04) or combination of immunopotentiators (QS-21 and MPL in AS01). Despite their distinctive features, most of these adjuvants share some key characteristics. For example, they induce early activation (although at different levels) of innate immunity which then translates into higher antibody and cellular responses to the vaccine antigens. In addition, most of these adjuvants (e.g. MF59, AS03, AS04) clearly induce a wider breadth of adaptive responses able to confer protection against, for example, heterovariants of the influenza viruses (MF59, AS03) or against human papillomavirus strains not contained in the vaccine (AS04). Finally, the use of some of these adjuvants has contributed to significantly enhance the immune response and the efficacy and effectiveness of vaccines in the elderly who experience a waning of the immune responsiveness to infection and vaccination, as shown for MF59- or AS03-adjuvanted influenza vaccines and AS01-adjuvanted herpes zoster vaccine. These results, together with the track record of acceptable safety profiles of the adjuvanted vaccines, pave the way for the development of novel vaccines at the extremes of age and against infections with a high toll of morbidity and mortality. Here, we review the mechanisms associated with the performance of those adjuvanted vaccines in animal models and in humans through recent advances in systems vaccinology and biomarker discovery. We also provide some perspectives on remaining knowledge gaps but also on opportunities that could accelerate the development of new vaccines.

Epidemiology, treatment and prevention of herpes zoster: A comprehensive review.

Herpes zoster is a major health burden that can affect individuals of any age. It is seen more commonly among individuals aged ≥50 years, those with immunocompromised status, and those on immunosuppressant drugs. It is caused by a reactivation of varicella zoster virus infection. Cell-mediated immunity plays a role in this reactivation. Fever, pain, and itch are common symptoms before the onset of rash. Post-herpetic neuralgia is the most common complication associated with herpes zoster. Risk factors and complications associated with herpes zoster depend on the age, immune status, and the time of initializing treatment. Routine vaccination for individuals over 60 years has shown considerable effect in terms of reducing the incidence of herpes zoster and post-herpetic neuralgia. Treatment with antiviral drugs and analgesics within 72 hours of rash onset has been shown to reduce severity and complications associated with herpes zoster and post-herpetic neuralgia. This study mainly focuses on herpes zoster using articles and reviews from PubMed, Embase, Cochrane library, and a manual search from Google Scholar. We cover the incidence of herpes zoster, gender distribution, seasonal and regional distribution of herpes zoster, incidence of herpes zoster among immunocompromised individuals, incidence of post-herpetic neuralgia following a zoster infection, complications, management, and prevention of herpes zoster and post-herpetic neuralgia.

A critical appraisal of 'Shingrix', a novel herpes zoster subunit vaccine (HZ/Su or GSK1437173A) for varicella zoster virus.

HZ/Su, branded as 'Shingrix', is one of the newest vaccines to be submitted for multi-national regulatory approval. It is targeted to prevent shingles, a global concern with aging populations. A live attenuated vaccine for shingles has been available for over a decade, however it is contraindicated in specific subgroups of people, and there are added concerns regarding long-term immunogenicity. HZ/Su is the first subunit vaccine developed to protect against shingles. This paper provides a critical appraisal of current evidence regarding HZ/Su.

Non-clinical safety assessment of single and repeated administration of gE/AS01 zoster vaccine in rabbits.

HZ/su is an investigational recombinant subunit vaccine for the prevention of shingles, a disease resulting from the reactivation of varicella zoster virus. The vaccine is composed of recombinant varicella zoster virus glycoprotein E (gE), and liposome-based Adjuvant System AS01. To evaluate the potential local and systemic effects of this vaccine, three studies were performed in rabbits. In the first two studies, rabbits received a single intramuscular (IM; study 1) or subcutaneous (SC; study 2) dose of gE/AS01, AS01 alone (in study 2 only) or saline, and the local tolerance was evaluated up to 3 days after administration. Under these conditions, only local inflammatory reactions at the injection sites were detected by microscopic evaluation. In the third study, gE/AS01, AS01 alone or saline, were injected SC or IM on four occasions at 2 week intervals. General health status, local tolerance, ophthalmology, haematology and blood chemistry parameters were monitored. Macroscopic and microscopic evaluations were performed after termination of the study. The only treatment-related changes included a transient increase in neutrophils, C-reactive protein and fibrinogen levels and microscopic signs of inflammation at the injection sites, which are expected observations related to the elicited inflammatory reaction. The SC and IM routes of administration produced similar systemic effects. However, microscopic findings at the injection sites differed. One month after the last injection, recovery was complete in all groups. In conclusion, the single and repeated SC and IM administration of the gE/AS01 vaccine were locally and systemically well-tolerated in rabbits and support the clinical development of the vaccine.

Preventative Care in the Patient with Inflammatory Bowel Disease: What Is New?

Patients with inflammatory bowel disease (IBD) do not receive routine preventative care at the same rate as general medical patients. This patient population is at increased risk of vaccine preventable illness such as influenza and pneumococcal pneumonia. This review will discuss health maintenance needs and preventative care issues in patients with IBD.

Positive Predictive Value of ICD-9 Code for Herpes Zoster Among Children During the Varicella Vaccine Era.

We examined the positive predictive value of the herpes zoster ICD-9 diagnosis code 053 in the Kaiser Permanente Northwest integrated health plan. Among children 0-17 years old, the positive predictive value was 87.1% (95% confidence interval: 84.2-89.6) and 96.8% (95% confidence interval: 95.0-98.1) during the years 1997-2002 and 2005-2009, respectively, using chart review of the medical record as the diagnostic standard.

Systemic Therapy for Psoriasis and the Risk of Herpes Zoster: A 500,000 Person-year Study.

IMPORTANCE: The risk for herpes zoster (HZ) in patients with psoriasis treated with biologic medications or other systemic treatments has been given little attention to date. OBJECTIVE: To describe the risk for HZ in patients with psoriasis and its relation to treatment. DESIGN, SETTING, AND PARTICIPANTS: A cohort study was performed using the administrative database of Clalit Health Services, the largest public health care provider organization in Israel, in the setting of general community clinics, primary care and referral centers, and ambulatory and hospitalized care. We extracted information for all patients who received a psoriasis diagnosis from January 2002 to June 2013. Follow-up was conducted until the end of July 2013. The study included 95,941 patients with psoriasis in the analysis, with 522,616 person-years of follow-up. Incidence of HZ events was calculated for each systemic antipsoriatic medication provided, during a follow-up period of 11 years and 7 months. We used a generalized estimating equation Poisson regression model to examine the effect of each systemic treatment for psoriasis on HZ incidence, adjusting for age, sex, psoriasis severity, Charlson comorbidity index, steroid treatment, and socioeconomic status. MAIN OUTCOMES AND MEASURES: Incidence of HZ associated with systemic therapies. RESULTS: In a multivariate analysis, it was observed that treatment with phototherapy (rate ratio [RR], 1.09 [95% CI, 0.62-1.93]; P = .99), methotrexate (RR, 0.98 [95% CI, 0.78-1.23]; P = .83), cyclosporine (RR, 1.16 [95% CI, 0.48-2.80]; P = .49), and biologic medications as a single agent (RR, 2.67 [95% CI, 0.69-10.3]; P = .14) was not associated with HZ. The use of combination treatment with biologic medications and methotrexate was significantly associated with an increased incidence of HZ (RR, 1.66 [95% CI, 1.08-2.57]; P = .02). The use of acitritin was associated with decreased incidence of HZ (RR, 0.69 [95% CI, 0.49-0.97]; P = .004). CONCLUSIONS AND RELEVANCE: Physicians may need to consider offering an HZ preventive vaccine to patients receiving combination treatment with biologic medications and methotrexate, particularly if they have additional risk factors for HZ.

The burden of Herpes Zoster and its complications in Poland in according to the age.

BACKGROUND: Incidence of shingles in different regions of the world ranged from 300 to 500/100,000 persons, and in the population older than 80 years of age reaches more than 1000/100,000. In the age group 50+ the incidence is enough high to be a serious medical and economic burden. Lack of details about the incidence and frequency of complications in Polish population let us too made an attempt to assess the scale of the problem, among others to the purpose of the evaluation of the legitimacy of implementing vaccination in the 50+ population. METHODS: First, based on coming data from the Swietokrzyskie Province Division of the National Health Fund we judged the incidence of shingles in this province in 2013 in individual ancient groups and depending on detailed diagnoses and with the division into the basic health, clinic and hospital care. Second, based on gathered data through NIZP-PZH, we judged hospital morbidity connected with shingles in Poland in 2008-2012 years, in individual ancient groups. RESULTS: Extrapolating the data from the Swietokrzyskie province we assess the incidence of shingles on average 338.8/100,000. She is tallest in the age group 50+ (614.3/100,000) and in this group also the most complications are being observed. Hospital morbidity in entire Poland showed in 2008-2012 years the frequency on average 4.93-5.42/100,000, in the group of 0-19 years; 0.10-1.50/100,000, in the group of 20-49 years; 4.9-5.42/100,000 and in the 50+ group--9.99-13.37/100,000. CONCLUSIONS: (1) Shingles, especially in the 50+ age group, constitutes a serious health problem in Poland, being a cause of numerous advices in basic health care and at clinics in Poland, as well of numerous hospitalizations and dangerous complications. (2) It seems, that active immunization against shingles, especially of 50+ persons, would be a favourable solution from the individual, as well as public perspective.
