Long-term efficacy data for the recombinant zoster vaccine: impact on public health and cost effectiveness in Germany

The aim of the study was to update previously published public health impact and cost-effectiveness analyses of the recombinant zoster vaccine (RZV), in the German population aged ≥50 years of age (YOA), with the latest vaccine efficacy (VE) estimates against herpes zoster (HZ). The updated estimates are derived from a long-term follow-up study. A previously published multi-cohort Markov model following age cohorts over their lifetime was used. Demographic, epidemiological, cost, and utility data were based on German specific sources. Vaccine coverage was assumed to be 40%, with a second dose compliance of 70%. The estimated VE at time 0 was 98.9% (95% C.I.: 94.0-100%) with an annual waning of 1.5% (95% CI: 0.0-3.4%) for the age group 50-69 YOA. Corresponding values were 95.4% (95% C.I.: 89.7-100%) and 2.3% (95% CI: 0.3-4.4%) for the age group ≥70 YOA. It was estimated that, over the remaining lifetime since vaccination, RZV would prevent approximately 884 thousand (K), 603 K, and 538 K HZ cases in three age cohorts 50-59, 60-69, and ≥70 YOA, respectively. The number needed to vaccinate to prevent one HZ and one postherpetic neuralgia case was 6 and 36 (50-59 YOA cohort), 6 and 34 (60-69 YOA cohort), 10 and 48 (≥70 YOA cohort). The incremental cost-effectiveness ratio of vaccination ranged from €26 K/quality-adjusted life year (QALY) in 60 YOA to €35 K/QALY in 70 YOA. Due to the higher, sustained, RZV VE, improved public health and cost-effectiveness results were observed compared to previous analyses.

Risk of Herpes Zoster Ophthalmicus Recurrence After Recombinant Zoster Vaccination

Article

作者: Sun, Yuwei ; Walia, Anushka ; Acharya, Nisha R

Importance:

The recombinant zoster vaccine (RZV) is currently recommended for immunocompetent adults aged 50 years or older and immunocompromised adults aged 19 years or older and is effective in preventing herpes zoster ophthalmicus (HZO). However, questions about the safety of RZV in patients with a history of HZO remain.

Objective:

To evaluate whether there is an increased risk of HZO recurrence after RZV in patients with a history of HZO.

Design, Setting, and Participants:

This retrospective cohort study used medical and outpatient pharmacy claims data for commercial and Medicare Advantage enrollees from the Optum Labs Data Warehouse. Patients with incident HZO from January 1, 2010, to December 31, 2021, were identified; the study period ended on March 31, 2022. The vaccinated group consisted of patients with at least 1 dose of RZV more than 90 days following the initial HZO diagnosis. The unvaccinated group consisted of patients without any record of RZV in the study period. Vaccinated and unvaccinated patients were matched using exact k:1 matching without replacement.

Exposure:

Recombinant zoster vaccination.

Main Outcomes and Measures:

The main outcome was the number of HZO recurrences with and without RZV exposure.

Results:

A total of 16 408 patients were included in the matched analysis, of whom 12 762 were unvaccinated (7806 [61.2%] female; mean [SD] age at diagnosis, 68.8 [10.3] years) and 3646 were vaccinated (2268 [62.2%] female; mean [SD] age at diagnosis, 67.4 [9.8] years). Within the primary risk period of 56 days after the index date (ie, the start of follow-up for the outcome), the incidence of HZO recurrence after any RZV exposure was 37.7 per 1000 person-years compared with 26.2 per 1000 person-years in the unexposed group. After controlling for race and ethnicity, inpatient stays, emergency department visits, concomitant vaccines, and eye care practitioner visits, the association between vaccination status and HZO exacerbation in the primary risk period had an adjusted hazard ratio for any RZV exposure of 1.64 (95% CI, 1.01-2.67; P = .04).

Conclusions and Relevance:

In this study, RZV exposure was associated with a higher likelihood of HZO recurrence in patients with a history of HZO compared with no RZV exposure. These findings support consideration that patients with a history of HZO may benefit from monitoring after receiving RZV in case of HZO recurrence.

Mitigating the Risk of Tofacitinib-induced Adverse Events in the Elderly Population with Ulcerative Colitis

Article

作者: Fries, Walter ; Viola, Anna ; Bivacqua, Chiara ; Costantino, Giuseppe ; Li Voti, Raffaele ; Muscianisi, Marco ; De Francesco, Clara

Abstract:

Background and Aims:

Older patients with ulcerative colitis treated with tofacitinib are at risk for major cardiovascular events, thromboembolism, herpes zoster, and malignancies and, accordingly, its use is limited by the regulatory authorities. The aim of the present study was to evaluate the occurrence of adverse events and potential preventive measures.

Methods:

We retrospectively evaluated patients treated with tofacitinib, divided into two groups according to comorbidities and age. Patient- and disease-related variables were recorded [primary non-response, loss of response, and persistence], together with deviations from the recommended induction regimen, ie, dose reduction, and concomitant treatments with anti-thrombotic therapy.

Results:

The age-adjusted Charlson comorbidity index of Group 1 [n = 30] was ≥2 and that of Group 2 [n = 37] was ≤ 1. No differences were observed for primary or secondary treatment failures. Both groups achieved comparable steroid-free remission rates at 12 months [53% and 46%, respectively]. Herpes zoster occurred in two patients per group, and no more cases occurred after strict recombinant zoster vaccination. No major cardiovascular event or thromboembolism was registered. Half of patients in Group 1 were treated with a reduced induction dose of 5 mg twice daily and 47% were on concomitant anti-thrombotic therapy. Malignancies were registered in two patients from Group 1 and one patient from Group 2.

Conclusions:

Modulation of induction dose and anti-thrombotic therapy may have contributed to prevent cardiological events and thromboembolism. The introduction of zoster vaccine virtually eliminated zoster risk after the first cases. Potential malignancies deserve a careful work-up of older patients before treatment start.
