BackgroundOptimal treatment for secondary hyperparathyroidism (SHPT) has not been defined. The IMPACT SHPT (ClinicalTrials.gov identifier: NCT00977080) study assessed whether dose-titrated paricalcitol plus supplemental cinacalcet only for hypercalcaemia is superior to cinacalcet plus low-dose vitamin D in controlling intact parathyroid hormone (iPTH) levels in patients with SHPT on haemodialysis.MethodsIn this 28-week, multicentre, open-label Phase 4 study, participants were randomly selected to receive paricalcitol or cinacalcet plus low-dose vitamin D. Randomization and analyses were stratified by mode of paricalcitol administration [intravenous (IV) or oral]. The primary efficacy end point was the proportion of subjects who achieved a mean iPTH value of 150–300 pg/mL during Weeks 21–28.ResultsOf 272 subjects randomized, 268 received one or more dose of study drug; 101 in the IV and 110 in the oral stratum with two or more values during Weeks 21–28 were included in the primary analysis. In the IV stratum, 57.7% of subjects in the paricalcitol versus 32.7% in the cinacalcet group (P = 0.016) achieved the primary end point. In the oral stratum, the corresponding proportions of subjects were 54.4% for paricalcitol and 43.4% for cinacalcet (P = 0.260). Cochran–Mantel–Haenszel analysis, controlling for stratum, revealed overall superiority of paricalcitol (56.0%) over cinacalcet (38.2%; P = 0.010) in achieving iPTH 150–300 pg/mL during Weeks 21–28. Hypercalcaemia occurred in 4 (7.7%) and 0 (0%) of paricalcitol-treated subjects in the IV and oral strata, respectively. Hypocalcaemia occurred in 46.9% and 54.7% of cinacalcet-treated subjects in the IV and oral strata, respectively.ConclusionParicalcitol versus cinacalcet plus low-dose vitamin D provided superior control of iPTH, with low incidence of hypercalcaemia.
Paricalcitol-treated patients experienced fewer hospitalizations and hospital days per year when compared with calcitriol-treated patients. Initiating vitamin D therapy with paricalcitol may result in overall savings of approximately 7600-11,000 US dollars per patient per year. A randomized, controlled, blinded study would be valuable in confirming and understanding these results.
The QICER Task Force recommends that ISPOR implement the following: * With respect to CER guidelines, that ISPOR promote harmonization of guidelines, allowing for differences in application, regional needs and politics; evaluate available instruments or promote development of a new one that will allow standardized quantification of the impact of CER guidelines on the quality of CER studies; report periodically on those countries or regions that have developed guidelines; periodically evaluate the quality of published studies (those journals with CER guidances) or those submitted to decision-making bodies (as public transparency increases). * With respect to methodologies, that ISPOR promote publication of methodological guidelines in more applied journals in more easily understandable format to transfer knowledge to researchers who need to apply more rigorous methods; promote full availability of models in electronic format to combat space restrictions in hardcopy publications; promote consistency of methodological review for all CER studies; promote adoption of explicit best practices guidelines among regulatory and reimbursement authorities; periodically update all ISPOR Task Force reports; periodically review use of ISPOR Task Force guidelines; periodically report on statistical and methodological challenges in HE; evaluate periodically whether ISPOR's methodological guidelines lead to improved quality; and support training and knowledge transfer of rigorous CER methodologies to researchers and health care decision-makers. * With respect to publications, that ISPOR develop standard CER guidances to which journals will be able to refer their authors and their reviewers; lobby to establish these guidances within the International Committee for Medical Journal Editors (ICMJE) Requirements to which most journals refer in their Author Instructions; provide support in terms of additional reviewer expertise to those journals lacking appropriate reviewers; periodically report on journals publishing CER research; periodically report on the quality of CER publications; and support training and knowledge transfer of the use of these guidelines to researchers and reviewers. * With respect to evidence-based health-care decision-making, that ISPOR recognize at its annual meetings those countries/agencies/private companies/researchers using CER well, and those practitioners and researchers supporting good patient use of CER in decision-making; and promote public presentation of case studies of applied use of CER concepts or guidelines.
A significantly greater prevalence of HGV/GBV-C was detected in urban volunteer blood donors than in rural donors. The high prevalence in urban donors (2.18%) suggests specific transmission risks for this group. The less than 50-percent efficiency of HGV/GBV-C transmission via blood components may indicate the presence of defective viruses with reduced infectivity. There is evidence for vertical transmission.
Introduction
Glecaprevir/pibrentasvir (G/P) was approved on 26 September 2019 by the US Food and Drug Administration for 8-week duration in treatment-naïve (TN) hepatitis C virus (HCV)-infected patients with compensated cirrhosis (CC). Evidence from the EXPEDITION-8 study demonstrated that 8 weeks of G/P achieved a 98% intent-to-treat (ITT) sustained virologic response rate 12 weeks post treatment (SVR12) in 343 TN/CC patients. The aim of this study is to demonstrate the first US real-world effectiveness of G/P 8-week treatment in genotype 1–6 TN/CC HCV patients.
Methods
Data from 73 TN/CC patients who initiated 8 weeks of G/P treatment between August 2017 and November 2018 were collected electronically from providers and specialty pharmacies of the Trio Health network and analyzed. Cirrhosis was determined by FIB-4 > 5.2 or was physician reported. The primary outcome was Per Protocol (PP) SVR12.
Results
The majority (60%) of patients were male, with (mean values): age 59 years, body mass index (BMI) of 30, aspartate aminotransferase (AST) 105, and alanine aminotransferase (ALT) 101 IU/ml. HCV genotypes (GT) were: GT1 81% (59/73), GT2 10% (7/73), GT3 5% (4/73), GT4 3% (2/73), and GT6 1% (1/73). Eight percent (6/73) of patients had concurrent proton pump inhibitor (PPI) use, and 15% (11/72) had a baseline viral load > 6 MM IU/ml. Zero patients discontinued, two patients were reported as lost to follow-up, and there was one virologic failure. PP sustained virologic response at 12 weeks (SVR12) rate was 99% (70/71), and the intent-to-treat (ITT) SVR12 rate was 96% (70/73).
Conclusions
Early real-world experience indicates high effectiveness of the 8-week G/P regimen in a diverse treatment-naïve, compensated cirrhotic US population.
Background/Aims: The objective of this study was to examine health care costs and utilization and the risks of dialysis or mortality among diabetic predialysis chronic kidney disease (CKD) patients with and without secondary hyperparathyroidism (SHPT). Methods: This retrospective, matched cohort study examined insurance claims from 703 adult diabetic predialysis CKD patients with and without SHPT during a 72-month follow-up period. Annualized estimates of health care service utilization, costs and disease progression to dialysis or death following index CKD diagnosis were compared. Results: Preindex (baseline) characteristics were similar between the cohorts. Postindex numbers of prescription utilization, outpatient service utilization and hospitalizations were all higher (p < 0.0001) in diabetic CKD patients with SHPT compared to those without SPHT in both unadjusted and adjusted analyses even after multivariate adjustment for known confounders. The rate of progression to dialysis or death was higher for diabetic CKD patients with SHPT compared to those without SPHT. Those with SHPT were at higher risk of requiring dialysis treatment [hazard ratio (HR) = 6.7; 95% confidence interval (CI) = 4.3–10.6] and death (HR = 2.3; 95% CI = 1.1–4.9) compared to those without SHPT. Conclusion: In diabetic predialysis CKD patients, the presence of SHPT is associated with significantly greater health care resource utilization and costs, and a faster rate of disease progression.
Over 65% of patients had endometriosis-related surgical procedures, including hysterectomy, within 1 year of being diagnosed with endometriosis. The cost of surgical procedures related to endometriosis places a significant financial burden on the healthcare system.
