Efficacy of a pentavalent rotavirus vaccine in reducing rotavirus-associated health care utilization across three regions (11 countries)
OBJECTIVE: To evaluate the effect of a human-bovine reassortant pentavalent rotavirus vaccine (PRV) on health care encounters in nearly 70 000 subjects randomized in three regions - Europe, the United States, and Latin America/the Caribbean - in the Rotavirus Efficacy and Safety Trial (REST). METHODS: Healthy 6- to 12-week-old infants received 3 doses of PRV or placebo at 4- to 10-week intervals. The exact binomial method for ratios of Poisson counts was used to evaluate the effect of PRV on the rate of rotavirus-related hospitalizations and emergency department (ED) visits involving rotavirus G-types 1-4 occurring > or =14 days after the third dose of vaccine for up to 2 years. RESULTS: In fully vaccinated infants, reductions in rotavirus-associated hospitalizations and ED visits were 94.7% (95% CI: 90.9, 96.9) in Europe, 94.9% (95% CI: 84.0, 98.9) in the United States, and 90.0% (95% CI: 29.4, 99.8) in the Latin American/Caribbean regions. CONCLUSIONS: PRV reduced hospitalizations and ED visits within each region in REST. Results were consistent across regions and across the overall study cohort
Effect of etranacogene dezaparvovec on quality of life for severe and moderately severe haemophilia B participants:Results from the phase III HOPE-B trial 2 years after gene therapy
Introduction:For people with haemophilia B (PwHB), bleeding may occur despite prophylaxis, negatively affecting health-related quality of life (HRQoL). The pivotal phase 3 HOPE-B trial investigating the adeno-associated virus gene transfer product, etranacogene dezaparvovec (EDZ), demonstrated sustained factor IX (FIX) activity and bleed protection in PwHB with baseline FIX levels ≤2%. Aim: Assess how EDZ affects HRQoL in HOPE-B trial participants. Methods: HRQoL was evaluated using generic and disease-specific patient reported outcomes (PROs) including the EQ-5D-5L and the Hem-A-QoL questionnaires. Mean domain and total scores were compared 6 months pre- and the first 2 years post-EDZ administration using repeated measures linear mixed models. The percentage of participants with minimal clinically important improvements in HRQoL was also evaluated. Results: Two years post-EDZ, there were nominally significant increases in the least squares (LS) mean score for the EQ-5D-5L Index Value (.04; p =.0129), reflecting better HRQoL. Nominally significant decreases in the LS mean scores, reflecting better HRQoL, were also found for the Hem-A-QoL total score (−6.0; p <.0001) and the Treatment (−13.94; p <.0001), Feelings (−9.01; p <.0001), Future (−6.45; p =.0004) and Work/School (−5.21; p =.0098) domains. The percentage of participants with ≥15-point improvement ranged from 45.83% (95% CI: 31.37%, 60.83%) for Treatment to 13.89% (95% CI: 4.67%, 29.50%) for Family Planning. Results were similar for Year 1. Conclusion:In conclusion, gene therapy with EDZ improved HRQoL in the first and second years in several Hem-A-QoL domains, including Treatment, Feelings, Work/School and Future domains, whereas improvement in other aspects of HRQoL were not demonstrated.</p
Efficacy of the Pentavalent Rotavirus Vaccine, RotaTeq (RV5), Between Doses of a 3-Dose Series and With Less Than 3 Doses (Incomplete Regimen)
Post-hoc analyses of the Rotavirus Efficacy and Safety Trial (RES T) were conducted to determine whether the pentavalent rotavirus vaccine (RV5) confers early protection against rotavirus gastroenteritis (RVGE) before completion of the 3-dose regimen. To evaluate the efficacy of RV5 between doses in reducing the rates of RVGE-related hospitalizations and emergency department (ED) visits in infants who ultimately received all 3 doses of RV5/placebo, events occurring from 2 weeks after the first and second doses to receipt of the subsequent dose (Analysis A) and events occurring from 2 weeks after the first and second doses to 2 weeks after the subsequent dose (Analysis B) were analyzed. In Analysis A, RV5 reduced the rates of combined hospitalizations and ED visits for G1-G4 RVGE or RVGE regardless of serotype between doses 1 and 2 by 100% [95% confidence interval (CI): 72-100%] or 82% (95% CI: 39-97%), respectively, and between doses 2 and 3, RV5 reduced the rates of combined hospitalizations and ED visits for G1-G4 RVGE or RVGE regardless of serotype by 91% (95% CI: 63-99%) or 84% (95% CI: 54-96%), respectively. Similar rate reductions were observed in Analysis B. These data suggest that RV5 provides a high level of protection between doses against hospitalizations and ED visits for RVGE starting as early as 14 days after the first dose

At US13.70 per 3-dose regimen, vaccination would cost US4,383 per discounted life-year saved, at a total net cost of US15 per dose, the cost per life-year saved is estimated to be lower than one GNP per capita and hence highly cost effective by the WHO Commission on Macroeconomics and Health criteria. The cost-effectiveness estimates are highly dependent upon the mortality in the absence of the vaccine, which suggests that the vaccine is likely to be significantly more cost-effective among poorer populations and among those with less access to prompt medical care – such that poverty reduction programs would be expected to reduce the future cost-effectiveness of the vaccine.</p
Acute/Subacute Herpes Zoster: Healthcare Resource Utilisation and Costs in a Group of US Health Plans
Background: Although there are estimated to be nearly 1 million cases of herpes zoster diagnosed in the US each year, the economic costs associated with herpes zoster in the US have not been well described. Objective: To describe the healthcare resource utilisation and costs associated with physician-diagnosed acute/subacute herpes zoster, from a payer perspective, using a large US healthcare claims database. Methods: Data for the period 2000-1 were obtained from the Medstat Marketscan healthcare claims database. The duration of acute/subacute herpes zoster was considered to include the 21 days preceding, and 90 days following, the initial herpes zoster diagnosis. Resource utilisation was examined for individuals with newly diagnosed acute/subacute herpes zoster (n_=_8741) and compared, through regression analyses, with that observed for control individuals from the same population (n_=_50_000). Similar analyses were conducted for costs; the costs included reflected healthcare payments from patients, insurers and other sources. Regression analyses controlled for demographics (age, gender), conditions that have been observed with greater frequency among patients with acute/subacute herpes zoster in prior studies (cancer, HIV infection, organ transplantation, other immunosuppressive conditions and therapies) and the number of billed services within each of seven categories of care that were potentially related to acute/subacute herpes zoster and that were utilised within the 30-180 days prior to the diagnosis for affected patients, and over an analogous period for controls. Results: The acute/subacute phase of herpes zoster was estimated to result in an average of 1.7 (standard error [SE] 0.02) additional physician and hospital outpatient visits, 0.05 (SE 0.003) additional emergency room visits, 0.03 (SE 0.003) additional inpatient hospital admissions, 2.1 (SE 0.03) additional prescriptions filled and US258 (SE 37.70) among patients aged =80 years. The numbers of additional outpatient visits, inpatient admissions, prescriptions filled for pain medications and coded complications were also substantially higher among older than younger patients with acute/subacute herpes zoster. Conclusions: The management of acute/subacute herpes zoster was found to result in substantial healthcare costs, with outpatient care and prescription drugs comprising the majority of the cost burden. To more fully understand the overall cost of herpes zoster disease to society, future studies should examine the healthcare costs associated with post-herpetic neuralgia and productivity losses due to herpes zoster and post-herpetic neuralgia.Cost-analysis, Cost-of-illness, Herpes-zoster, Resource-use

National economic impact of tirofiban for unstable angina and myocardial infarction without ST elevation; example from the United Kingdom
Acute coronary syndromes without ST elevation are a major health and economic burden. Treatments such as glycoprotein IIb/IIIa antagonists like tirofiban reduce the risk of complications but the cost impact of these agents including cost offsets of avoiding complications are needed particularly in Europe
