Objectives: This study examined the effectiveness of nirmatrelvir plus ritonavir (NMV-r) and molnupiravir (MOV) in treating COVID-19 among chronic kidney disease (CKD) patients. Methods: This retrospective cohort study, using the TriNetX research network, identified stage 3–5 CKD and end-stage kidney disease (ESKD) patients with non-hospitalized COVID-19 between 1 January 2022, and 31 May 2023. Propensity score matching (PSM) was used to compare patients on NMV-r or MOV (antiviral group) against those not receiving these treatments (control group). The primary composite outcome was the cumulative hazard ratio (HR) for all-cause hospitalization or death within the 30-day follow-up. Results: After PSM, two balanced cohorts of 6,275 patients each were established. The antiviral group exhibited a lower incidence of all-cause hospitalization or mortality (5.93% vs. 9.53%; HR: 0.626; 95% CI: 0.550–0.713) than controls. Additionally, antiviral recipients were associated with a lower risk of all-cause hospitalization (HR: 0.679; 95% CI: 0.594–0.777) and mortality (HR: 0.338; 95% CI: 0.227–0.504). The beneficial effects of antiviral agents were consistent across sex, age, vaccination status, antiviral type, and CKD stage. Conclusion: Oral antiviral agents could be associated with lower rates of all-cause hospitalization or death among non-hospitalized COVID-19 patients with CKD. [ABSTRACT FROM AUTHOR]

Aims: Heart failure with reduced ejection fraction (HFrEF) significantly impacts health‐related quality of life (HR‐QoL). Existing HR‐QoL questionnaires can show inconsistencies, potentially misrepresenting patient self‐reports. This study examines the variation in HR‐QoL measurement tools for HFrEF patients, identifying related determinants. Methods and results: We retrospectively analysed 134 hospitalized patients with acute decompensated HFrEF at a Taiwanese tertiary centre's Heart Failure Post‐Acute‐Care (HF‐PAC) programme. Participants completed the EuroQol‐5 dimension (EQ‐5D) questionnaire, the EQ‐5D visual analogue scale (VAS), and the Minnesota Living with Heart Failure Questionnaire (MLHFQ). Utility values were obtained from the EQ‐5D questionnaire. Demographic features were depicted using descriptive statistics, while multivariate regression was used to ascertain relationships between HR‐QoL measurements and determinants. Average scores for EQ‐5D, MLHFQ, EQ‐5D utility, and VAS were 6.1 ± 1.6, 21.8 ± 21.3, 81.7 ± 27.0, and 59.5 ± 14.6, respectively. Significant correlations were observed among the three tools. The New York Heart Association functional class showed a notable association with all tool scores. Other associations encompassed EQ‐5D with coronary artery disease, mineralocorticoid receptor antagonists, and the 6 min walk test; EQ‐5D VAS with chronic kidney disease; and MLHFQ with age. Conclusions: This study illuminates the variance in HR‐QoL measurement tools for Taiwanese HFrEF patients. Using a range of these tools is beneficial in unveiling diverse determinants and approaching comprehensive patient‐centred care. However, for a more precise HR‐QoL assessment in Taiwanese HFrEF patients, recalibrating the EQ‐5D‐derived utility scores might be necessary, emphasizing the importance of patient‐specific considerations within the HF‐PAC programme.

Introduction: Although angiotensin receptor-neprilysin inhibitor (ARNI) has shown promise in patients with heart failure and reduced ejection fraction (HFrEF), the treatment effect in HFrEF patients with end-stage renal disease (ESRD) undergoing dialysis is uncertain. This study aimed to examine the real-world effects of ARNI vs. angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEI/ARB) in this subpopulation., Methods: This multi-institutional, retrospective study identified 349 HFrEF patients with ESRD on dialysis, who initiated either ARNI or ACEI/ARB therapy. Efficacy outcomes included rates of hospitalization for heart failure (HHF) and mortality, as well as changes in echocardiographic parameters. Safety outcomes encompassed hypotension and hyperkalemia. Treatment effects were assessed using Cox proportional hazards models, with additional sensitivity analyses for robustness., Results: Out of 349 patients screened, 89 were included in the final analysis (42 in the ARNI group and 47 in the ACEI/ARB group). After 1 year of treatment, echocardiographic measures between the two groups were comparable. The primary composite rate of HHF or mortality was 20.6 events per 100 patient-years in the ARNI group and 26.1 in the ACEI/ARB group; the adjusted hazard ratio was 0.98 (95% CI: 0.28-3.43, P  = 0.97). Their safety outcomes did not differ significantly. Sensitivity analyses, including repetitive sampling, propensity score matching, and extended follow-up, corroborated these findings., Conclusion: ARNI has proven effective in treating HFrEF patients; however, significant benefits were not observed in these patients with ESRD undergoing dialysis compared with ACEI/ARB in this real-world cohort. Future research employing a more extended follow-up period, larger sample size, or randomized design is warranted to investigate the treatment effects in this subpopulation., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Yang, Huang, Yang, Toh, Chang, Su, Lin, Wang, Wang and Liao.)
