RESUMEN

BACKGROUND: Sodium-glucose cotransporter-2 inhibitors have emerged as a key pharmacotherapy in heart failure (HF) with both reduced and preserved ejection fraction. The benefit of other HF therapies may be modified by sex, but whether sex modifies the treatment effect and safety profile of sodium-glucose cotransporter-2 inhibitors remains unclear. Our analyses aim to assess the effect of sex on the efficacy and safety of dapagliflozin. METHODS: In a prespecified patient-level pooled analysis of DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) and DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure), clinical outcomes were compared by sex (including the composite of cardiovascular death or worsening HF events, cardiovascular death, all-cause death, total events [first and recurrent HF hospitalization and cardiovascular death], and Kansas City Cardiomyopathy Questionnaire scores) across the spectrum of left ventricular ejection fraction. RESULTS: Of a total of 11 007 randomized patients, 3856 (35%) were women. Women with HF were older and had higher body mass index but were less likely to have a history of diabetes and myocardial infarction or stroke and more likely to have hypertension and atrial fibrillation compared with men. At baseline, women had higher ejection fraction but worse Kansas City Cardiomyopathy Questionnaire scores than men did. After adjustment for baseline differences, women were less likely than men to experience cardiovascular death (adjusted hazard ratio, 0.69 [95% CI, 0.60-0.79]), all-cause death (adjusted hazard ratio, 0.69 [95% CI, 0.62-0.78]), HF hospitalizations (adjusted hazard ratio, 0.82 [95% CI, 0.72-0.94]), and total events (adjusted rate ratio, 0.77 [95% CI, 0.71-0.84]). Dapagliflozin reduced the primary end point in both men and women similarly (Pinteraction=0.77) with no sex-related differences in secondary outcomes (all Pinteraction>0.35) or safety events. The benefit of dapagliflozin was observed across the entire ejection fraction spectrum and was not modified by sex (Pinteraction>0.40). There were no sex-related differences in serious adverse events, adverse events, or drug discontinuation attributable to adverse events. CONCLUSIONS: In DAPA-HF and DELIVER, the response to dapagliflozin was similar between men and women. Sex did not modify the treatment effect of dapagliflozin across the range of ejection fraction.

RESUMEN

BACKGROUND: The importance and value of involvement of people with lived experience of suicide has been recognized in suicide research and prevention. Nonetheless, clear guidance on research collaboration and co-production is lacking. This study aimed to address this gap by developing a set of guidelines on active involvement of people with lived experience of suicide in suicide studies., i.e., conducting research with or by people with lived experience, rather than to, about or for them. METHODS: The Delphi method was used to determine statements on best practice for the active involvement of people with lived experience of suicide in suicide research. Statements were compiled through a systematic search of the scientific and grey literature, and reviewing qualitative data from a recent related study conducted by the authors. Two expert panels: people with lived experience of suicide (n = 44) and suicide researchers (n = 29) rated statements over three rounds of an online survey. Statements endorsed by at least 80% of panellists of each panel were included in the guidelines. RESULTS: Panellists endorsed 96 out of 126 statements in 17 sections covering the full research cycle from deciding on the research question and securing funding, to conducting research and disseminating and implementing outcomes. Overall, there was a substantial level of agreement between the two panels regarding support from research institutions, collaboration and co-production, communication and shared decision making, conducting research, self-care, acknowledgment, and dissemination and implementation. However, panels also disagreed on specific statements regarding representativeness and diversity, managing expectations, time and budgeting, training, and self-disclosure. CONCLUSIONS: This study identified consensus recommendations on active involvement of people with lived experience of suicide in suicide research, including co-production. Support from research institutions and funders, and training on co-production for researchers and people with lived experience, are needed for successful implementation and uptake of the guidelines.

RESUMEN

BACKGROUND: Solid-organ transplant (SOT) recipients with coronavirus disease 2019 (COVID-19) have higher risk of adverse outcomes compared to the general population. Whether hospitalized SOT recipients with COVID-19 are at higher risk of mortality than SOT recipients hospitalized for other causes, including non-COVID-19 pneumonia, remains unclear. METHODS: We used logistic regression to compare outcomes of SOT recipients hospitalized with COVID-19 to non-COVID-19 related admissions and with non-COVID-19 pneumonia. RESULTS: Of 17,012 hospitalized SOT recipients, 1682 had COVID-19. Those with COVID-19 had higher odds of ICU admission (adjusted odds ratio [aOR] 2.12 [95%CI: 1.88-2.39]) and mechanical ventilation (aOR 3.75 [95%CI: 3.24-4.33]). COVID-19 was associated with higher odds of in-hospital death, which was more pronounced earlier in the pandemic (aOR 9.74 [95%CI: 7.08-13.39] for April/May vs. aOR 7.08 [95%CI: 5.62-8.93] for June through November 2020; P-interaction = .03). Compared to SOT recipients hospitalized with non-COVID-19 pneumonia, odds of in-hospital death were higher in SOT recipients with COVID-19 (aOR 2.44 [95% CI: 1.90-3.13]), regardless of time of hospitalization (P-interaction > .40). CONCLUSIONS: In this large cohort of SOT recipients, hospitalization with COVID-19 was associated with higher odds of complications and in-hospital mortality than non-COVID-19 related admissions, and 2.5-fold higher odds of in-hospital mortality, compared to SOT recipients with non-COVID-19 pneumonia.

RESUMEN

This study explored reasons for living among those with lived experience of suicide entering the suicide prevention workforce. The study recruited 110 participants from two Roses in the Ocean training programs (79% female, mean age 46.5). Responses to open-ended survey questions about reasons for living were analyzed using qualitative content analysis method. Connection to others and service were the most commonly stated reasons for living. Other categories included orientation toward future, life, self, pleasure, and spiritual reasons and values. These findings can be used in further research and design of support programs for peer specialists.

RESUMEN

Despite increased participation and multiple workforce roles of those with lived experience in suicide prevention, there are no evaluated training programs to support this population. This study evaluated a training program aimed to prepare people for these important roles. Survey data at pre-, post- and at three- and 12-month follow-up were used measuring knowledge, attitudes, and self-efficacy, as well as psychological distress as a safety measure. Participants experienced significant gains in knowledge after training, although not all aspects of knowledge were maintained at follow-up. Self-efficacy was examined through confidence and empowerment. Confidence gains were significant at immediate and longer-term follow-up but gains in empowerment were not maintained over time. Participants' positive attitudes improved but this was not significant. There was no indication of increases in psychological distress in participants throughout the training and follow-up periods. Implications of these outcomes are discussed.

RESUMEN

BACKGROUND: In patients with heart failure, chronic kidney disease is common and associated with a higher risk of renal events than in patients without chronic kidney disease. We assessed the renal effects of angiotensin/neprilysin inhibition in patients who have heart failure with preserved ejection fraction enrolled in the PARAGON-HF trial (Prospective Comparison of ARNI With ARB Global Outcomes in HF With Preserved Ejection Fraction). METHODS: In this randomized, double-blind, event-driven trial, we assigned 4822 patients who had heart failure with preserved ejection fraction to receive sacubitril/valsartan (n=2419) or valsartan (n=2403). Herein, we present the results of the prespecified renal composite outcome (time to first occurrence of either: ≥50% reduction in estimated glomerular filtration rate (eGFR), end-stage renal disease, or death from renal causes), the individual components of this composite, and the influence of therapy on eGFR slope. RESULTS: At randomization, eGFR was 63±19 mL·min-1·1.73 m-2. At study closure, the composite renal outcome occurred in 33 patients (1.4%) assigned to sacubitril/valsartan and 64 patients (2.7%) assigned to valsartan (hazard ratio, 0.50 [95% CI, 0.33-0.77]; P=0.001). The treatment effect on the composite renal end point did not differ according to the baseline eGFR (<60 versus ≥60 mL·min-1·1.73 m-2 (P-interaction=0.92). The decline in eGFR was less for sacubitril/valsartan than for valsartan (-2.0 [95% CI, -2.2 to -1.9] versus -2.7 [95% CI, -2.8 to -2.5] mL·min-1·1.73 m-2 per year). CONCLUSIONS: In patients with heart failure with preserved ejection fraction, sacubitril/valsartan reduced the risk of renal events, and slowed decline in eGFR, in comparison with valsartan.

RESUMEN

Cryptococcus gattii infection is a rare cause of severe pulmonary disease and meningoencephalitis that has only recently been detected in the southeastern United States. We describe an organ transplant-associated outbreak of C. gattii infection involving an HIV-negative immunosuppressed donor in this region who died following new-onset headache and seizure of unknown cause. Retrospective cryptococcal antigen (CrAg) testing of donor serum was positive. Two of the three transplant recipients developed severe C. gattii infection 11 and 12 weeks following transplantation. One recipient died from severe pulmonary infection, identified on autopsy, and the other ill recipient survived following treatment for cryptococcal meningitis. This outbreak underscores the importance of considering cryptococcosis in patients with clinical findings suggestive of subacute meningitis or other central nervous system (CNS) pathology, and the potential benefit of routine pre-transplant donor CrAg screening using lateral flow assay to guide recipient antifungal prophylaxis. The case also adds to emerging evidence that C. gattii is a potential threat in the southeastern United States.

RESUMEN

PURPOSE OF REVIEW: T-cell immunoglobulin and mucin domain-containing molecule (TIM)4 is a costimulatory molecule and phosphatidylserine receptor. Its dominant function varies according to the expressing cell and site of activation. In recent years, studies have identified its role in diverse disease processes and increasingly in alloimmunity. Herein, we will comprehensively review the literature on TIM4 and outline its function in shaping the alloimmune response. RECENT FINDINGS: TIM4 expression on dendritic cells increases following transplantation. Blockade of TIM4 in vivo leads to increased differentiation of regulatory T cells and improved allograft survival. TIM4 binds phosphatidylserine-expressing apoptotic cells. Previously thought of as a tethering molecule, recent studies have demonstrated that TIM4 interacts with integrins to mediate uptake of apoptotic cells. TIM4 B cells have recently been identified, which produce high levels of IFNγ and promote allograft rejection. Targeting these B cells improved allograft survival and promoted the development of TIM1 regulatory B cells. SUMMARY: TIM4 is expressed in niche compartments and has many immunological effects. However, inhibition of TIM4 has been demonstrated to prolong allograft survival, through varied mechanisms. A unifying explanation for the role of TIM4 in alloimmunity remains to be found, but this pathway appears to hold considerable promise in transplantation.

RESUMEN

Early recovery from shock improves prognosis in patients with severe sepsis and septic shock. During this period, cytokine imbalances mediate the development of organ damage and mortality. In Japan, we have access to hemoperfusion using an immobilized polymyxin B fiber column for endotoxin removal (PMX-DHP) and continuous hemodiafiltration (CHDF) as artificial support for patients with septic shock, with the aim of improving hemodynamics and organ dysfunction caused by elevated inflammatory cytokines and mediators. In this Short communication, we discuss recent findings showing anti-inflammatory treatment following these continuous renal replacement therapies in sepsis.

RESUMEN

Dendritic cells (DCs) are the central architects of the immune response, inducing inflammatory or tolerogenic immunity, dependent on their activation status. As such, DCs are highly attractive therapeutic targets and may hold the potential to control detrimental immune responses. TIM-4, expressed on APCs, has complex functions in vivo, acting both as a costimulatory molecule and a phosphatidylserine receptor. The effect of TIM-4 costimulation on T cell activation remains unclear. In this study, we demonstrate that Ab blockade of DC-expressed TIM-4 leads to increased induction of induced regulatory T cells (iTregs) from naive CD4(+) T cells, both in vitro and in vivo. iTreg induction occurs through suppression of IL-4/STAT6/Gata3-induced Th2 differentiation. In addition, blockade of TIM-4 on previously activated DCs still leads to increased iTreg induction. iTregs induced under TIM-4 blockade have equivalent potency to control and, upon adoptive transfer, significantly prolong skin allograft survival in vivo. In RAG(-/-) recipients of skin allografts adoptively transferred with CD4(+) T cells, we show that TIM-4 blockade in vivo is associated with a 3-fold prolongation in allograft survival. Furthermore, in this mouse model of skin transplantation, increased induction of allospecific iTregs and a reduction in T effector responses were observed, with decreased Th1 and Th2 responses. This enhanced allograft survival and protolerogenic skewing of the alloresponse is critically dependent on conversion of naive CD4(+) to Tregs in vivo. Collectively, these studies identify blockade of DC-expressed TIM-4 as a novel strategy that holds the capacity to induce regulatory immunity in vivo.

RESUMEN

BACKGROUND: Kidney transplant recipients are at increased risks of cardiovascular events, but contemporary risk estimates are sparse. Using the Danish nationwide administrative databases, we quantified 1- and 5-year risks of cardiovascular disease and kidney failure among all first-time kidney transplant recipients (2005-2018) and age- and sex-matched controls (1:10 ratio). METHODS: Cumulative 1- and 5-year incidence of cardiovascular events (myocardial infarction, stroke, or heart failure), kidney failure (re-transplantation or need for dialysis >30 days post-transplant), and mortality following transplantation were calculated until maximally Dec 31, 2018. RESULTS: A total of 2,565 kidney transplant recipients (median age 50.5 [25-75th percentile 40.2-60.7] years, 37 % females) and 25,650 controls were included. 1-year cumulative incidence of myocardial infarction, stroke, or heart failure was 2.6 % (95 % confidence interval 1.9 %-3.2 %) among kidney transplant recipients versus 0.5 % (0.4 %-0.5 %) in controls. Cumulative 5-year risk estimates for the same endpoints were 8.3 % (7.1 %-9.5 %) for the transplant patients, and 2.6 % (2.3 %-2.8 %) among controls, respectively. For the kidney transplant cohort, cumulative mortality was 2.2 % (1.7 %-2.8 %) and 10.3 % (9.0 %-11.6 %) at 1- and 5 years, respectively, versus 0.5 % (0.4 %-0.6 %) and 3.0 % (2.7 %-3.2 %) for controls. The cumulative incidence of dialysis and re-transplantation was 6.1 % (5.2 %-7.1 %) at 1 year and 16.3 % (14.7 %-17.9 %) at 5 years, respectively. CONCLUSIONS: Despite the benefits of transplantation, kidney transplant recipients continue to have significant long-term cardiovascular disease, end-stage kidney disease, and mortality risks even with contemporary medical management. Better cardiovascular preventive strategies are warranted to improve prognosis in this segment of patients.

RESUMEN

Importance: An initial decline in estimated glomerular filtration rate (eGFR) is expected after initiating a sodium-glucose cotransporter-2 inhibitor (SGLT2i) and has been observed across patients with diabetes, chronic kidney disease, and heart failure. Objective: To examine the implications of initial changes in eGFR among patients with heart failure with mildly reduced ejection fraction (HFmrEF) or preserved ejection fraction (HFpEF) enrolled in the Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure (DELIVER) trial. Design, Setting, and Participants: This was a prespecified analysis of the results of the DELIVER randomized clinical trial, which was an international multicenter study of patients with EF greater than 40% and eGFR greater than or equal to 25. The DELIVER trial took place from August 2018 to March 2022. Data for the current prespecified study were analyzed from February to October 2023. Intervention: Dapagliflozin, 10 mg per day, or placebo. Main Outcomes and Measures: In this prespecified analysis, the frequency of an initial eGFR decline (baseline to month 1) was compared between dapagliflozin and placebo. Cox models adjusted for baseline eGFR and established prognostic factors were fit to estimate the association of an initial eGFR decline with cardiovascular (cardiovascular death or heart failure event) and kidney (≥50% eGFR decline, eGFR<15 or dialysis, death from kidney causes) outcomes, landmarked at month 1, stratified by diabetes. Results: Study data from 5788 participants (mean [SD] age, 72 [10] years; 3253 male [56%]) were analyzed. The median (IQR) change in eGFR level from baseline to month 1 was -1 (-6 to 5) with placebo and -4 (-9 to 1) with dapagliflozin (difference, -3; P < .001). A higher proportion of patients assigned to dapagliflozin developed an initial eGFR decline greater than 10% vs placebo (1144 of 2892 [40%] vs 737 of 2896 [25%]; odds ratio, 1.9; 95% CI, 1.7-2.1; P difference <.001). An initial eGFR decline of greater than 10% (vs ≤10%) was associated with a higher risk of the primary cardiovascular outcome among those randomized to placebo (adjusted hazard ratio [aHR], 1.33; 95% CI, 1.10-1.62) but not among those randomized to dapagliflozin (aHR, 0.90; 95% CI, 0.74-1.09; P for interaction = .01). Similar associations were observed when alternative thresholds of initial eGFR decline were considered and when analyzed as a continuous measure. An initial eGFR decline of greater than 10% was not associated with adverse subsequent kidney composite outcomes in dapagliflozin-treated patients (aHR, 0.94; 95% CI, 0.49-1.82). Conclusions and Relevance: Among patients with HFmrEF or HFpEF treated with dapagliflozin, an initial eGFR decline was frequent but not associated with subsequent risk of cardiovascular or kidney events. These data reinforce clinical guidance that SGLT2is should not be interrupted or discontinued in response to an initial eGFR decline. Trial Registration: ClinicalTrials.gov Identifier: NCT03619213.

RESUMEN

AIM: It is unknown whether safety and clinical endpoints by use of sacubitril/valsartan (an angiotensin receptor-neprilysin inhibitor [ARNI]) are affected by mineralocorticoid receptor antagonists (MRA) in high-risk myocardial infarction (MI) patients. The aim of this study was to examine whether MRA modifies safety and clinical endpoints by use of sacubitril/valsartan in patients with a MI and left ventricular systolic dysfunction (LVSD) and/or pulmonary congestion. METHODS AND RESULTS: Patients (n = 5661) included in the PARADISE MI trial (Prospective ARNI vs. ACE Inhibitor Trial to Determine Superiority in Reducing Heart Failure Events After MI) were stratified according to MRA. Primary outcomes in this substudy were worsening heart failure or cardiovascular death. Safety was defined as symptomatic hypotension, hyperkalaemia >5.5 mmol/L, or permanent drug discontinuation. A total of 2338 patients (41%) were treated with MRA. Safety of ARNI compared to ramipril was not altered significantly by ± MRA, and both groups had similar increase in symptomatic hypotension with ARNI. In patients taking MRA, the risk of hyperkalaemia or permanent drug discontinuation was not significantly altered by ARNI (p > 0.05 for all comparisons). The effect of ARNI compared with ramipril was similar in those who were and were not taking MRA (hazard ratio [HR]MRA 0.96, 95% confidence interval [CI] 0.77-1.19 and HRMRA- 0.87, 95% CI 0.71-1.05, for the primary endpoint; p = 0.51 for interaction [Clinical Endpoint Committee adjudicated]); similar findings were observed if investigator-reported endpoints were evaluated (p = 0.61 for interaction). CONCLUSIONS: Use of a MRA did not modify safety or clinical endpoints related to initiation of ARNI compared to ramipril in the post-MI setting in patients with LVSD and/or congestion.

RESUMEN

Ligands of the B7 family provide both positive and negative costimulatory signals to the CD28 family of receptors on T lymphocytes, the balance of which determines the immune response. B7-H3 is a member of the B7 family whose function in T-cell activation has been the subject of some controversy: in autoimmunity and tumor immunity, it has been described as both costimulatory and coinhibitory, while in transplantation, B7-H3 signaling is thought to contribute to graft rejection. However, we now demonstrate results to the contrary. Signaling through a putative B7-H3 receptor prolonged allograft survival in a fully MHC-mismatched cardiac model and promoted a shift toward a Th2 milieu; conversely, B7-H3 blockade, achieved by use of a blocking antibody, resulted in accelerated rejection, an effect associated with enhanced IFN-γ production. Finally, graft prolongation achieved by CTLA4 Ig was shortened both by B7-H3 blockade and the absence of recipient B7-H3. These findings suggest a coinhibitory role for B7-H3. However, experience with other CD28/B7 family members suggests that immune redundancy plays a crucial role in determining the functions of various pathways. Given the abundance of conflicting data, it is plausible that, under differing conditions, B7-H3 may have both positive and negative costimulatory functions.

RESUMEN

Many adults experience mental health problems or suicidality. Mental health and suicidality are associated with stigma and discrimination. Little is known about disclosure of mental health or suicidality problems in workplaces and the role of stigma and discrimination in affecting disclosure. To address this gap, we conducted a systematic review following the PRISMA guidelines. Searches for peer-reviewed articles in MedLINE, CINAHL, Embase and PsycINFO identified 26 studies, including sixteen qualitative, seven quantitative and three mixed-methods studies. No studies were excluded based on quality assessment. All studies reported on mental health disclosure; none reported on disclosure of suicidal thoughts or behaviours. The narrative synthesis identified four overarching themes relating to disclosure of mental health problems in workplaces. Themes included beliefs about stigma and discrimination, workplace factors (including supports and accommodation), identity factors (including professional and personal identity, gender and intersectionality) and factors relating to the disclosure process (including timing and recipients), with all influencing disclosure decision making. Significantly, this review found that there is a gap in the existing literature relating to suicidality disclosure in workplaces, with none of the included studies investigating disclosure of suicidal thoughts and behaviours.

RESUMEN

BACKGROUND: Currently, there is no comprehensive study focused on identifying what is needed to support ongoing participation within the suicide prevention lived experience workforce (LEW). It is unclear what specific factors may impede or support ongoing participation in the LEW. The aim of this study was to explore the experiences of suicide prevention LEW in terms of its sustainability. METHOD: A qualitative interview method was utilised, with a purposive sample of participants who had engaged in the LEW for at least 12 months. The sample comprised 13 individuals (nine females, four males) who engaged in multiple LEW roles, with over half (54%) working in the LEW for more than 5 years. Data were analysed using thematic analysis. RESULTS: Five main themes were identified: support, passion, personal impact, training, and work diversity. Each theme offers perspectives about the challenges participants face within the suicide prevention LEW. CONCLUSION: Challenges faced are both similar to those found in the broader MH sector and unique to suicide prevention. Findings suggest that managing expectations of the LEW is important and can inform the creation of guidelines for a supported and sustainable suicide prevention LEW.

RESUMEN

BACKGROUND/OBJECTIVES: To investigate the effectiveness, feasibility, and acceptability of sense of purpose (SOP) interventions in preventing or reducing anxiety or depression in youth aged 14-24 years. METHODS: A systematic search was conducted of the academic (PubMed/MEDLINE, PsycINFO, EMBASE) and grey literature. We also consulted two SOP experts and an Australian and Indian youth advisory group with lived experience of anxiety and/or depression. Consultations focused on the feasibility and acceptability of reviewed interventions. RESULTS: The search identified 25 studies reporting on 4408 participants from six countries (64.0 % of studies in the US). Multi-component interventions targeting several SOP components (i.e., value clarification, goal setting, gratitude enhancement) reported, on average, moderate reductions in depression and anxiety symptoms in youth. Interventions were generally more effective at reducing depression than anxiety symptoms. In terms of sub-populations or groups, there was some evidence for greater intervention effectiveness among youth with prior therapy experience, extraverted personalities, and those with already elevated anxiety/depression symptoms. Youth advisors and experts opined that group interventions were most acceptable to young people. LIMITATIONS: This review was limited to a recent 10-year timeframe and publications in English, potentially excluding relevant studies published prior to 2011 or in other languages. CONCLUSIONS: Fostering SOP can lead to better psychological wellbeing in youth. Potential harms resulting from interventions can occur without adequate consideration for a person's readiness for purpose discovery, environmental barriers, and familial and cultural settings. Further research in more diverse populations is required to determine who benefits and in what contexts.

RESUMEN

Importance: Sodium-glucose cotransporter 2 inhibitors are known to reduce heart failure events and slow progression of kidney disease among patients with heart failure and a reduced ejection fraction. Objective: To determine the effect of dapagliflozin on cardiovascular and kidney outcomes and the influence of baseline kidney disease among patients with heart failure and a mildly reduced or preserved ejection fraction enrolled in the Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure (DELIVER) trial. Design, Setting, and Participants: This was a prespecified analysis conducted from July 1 to September 18, 2022 of the DELIVER randomized clinical trial. This was an international, multicenter trial including patients with ejection fraction greater than 40% and estimated glomerular filtration rate (eGFR) of 25 mL/min/1.73 m2 or higher. Interventions: Dapagliflozin, 10 mg, per day or placebo. Main Outcomes and Measures: Outcomes assessed were whether baseline kidney function modified the treatment effect on the primary outcome (cardiovascular death or worsening heart failure). Also examined was the treatment effect on the prespecified outcomes of eGFR slope and a post hoc composite kidney outcome (first ≥50% decline in eGFR from baseline; first eGFR <15 mL/min/1.73 m2; end-stage kidney disease; death from kidney causes). Results: A total of 6262 patients (mean [SD] age, 72 [10] years; 3516 male [56%]) had mean (SD) eGFR measurements available: 61 (19) mL/min/1.73 m2; 3070 patients (49%) had an eGFR less than 60 mL/min/1.73 m2. The effect of dapagliflozin on the primary outcome was not influenced by baseline eGFR category (eGFR ≥60 mL/min/1.73 m2: hazard ratio [HR], 0.84; 95% CI, 0.70-1.00; eGFR 45-<60 mL/min/1.73 m2: HR, 0.68; 95% CI, 0.54-0.87; eGFR <45 mL/min/1.73 m2: HR, 0.93; 95% CI, 0.76-1.14; P for interaction = .16). Over a median (IQR) follow-up of 2.3 (1.7-2.8) years, the overall incidence rate of the kidney composite outcome was low (1.1 events per 100 patient-years) and was not affected by treatment with dapagliflozin (HR, 1.08; 95% CI, 0.79-1.49). However, dapagliflozin attenuated the decline in eGFR from baseline (difference, 0.5; 95% CI, 0.1-0.9 mL/min/1.73 m2 per year; P = .01) and from month 1 to 36 (difference, 1.4; 95% CI, 1.0-1.8) mL/min/1.73 m2 per year; P < .001). Conclusions and Relevance: Results of this prespecified analysis showed that baseline kidney function did not modify the benefit of dapagliflozin in patients with heart failure and a mildly reduced or preserved ejection fraction. Dapagliflozin did not significantly reduce the frequency of the kidney composite outcome, although the overall event rate was low. However, dapagliflozin slowed the rate of decline in eGFR compared with placebo. Trial Registration: ClinicalTrials.gov Identifier: NCT03619213.

RESUMEN

AIMS: Patients with heart failure are at higher risk of progression to end-stage renal disease (ESRD), regardless of ejection fraction (EF). We assessed the renal effects of angiotensin-neprilysin inhibition in a pooled analysis of 13 195 patients with heart failure with reduced and preserved EF. METHODS AND RESULTS: We combined data from PARADIGM-HF (EF ≤40%; n = 8399) and PARAGON-HF (EF ≥45%; n = 4796) in a pre-specified pooled analysis. We assessed the effect of treatment (sacubitril/valsartan vs. enalapril or valsartan) on a composite of either ≥50% reduction in estimated glomerular filtration rate (eGFR), ESRD, or death from renal causes, in addition to changes in eGFR slope. We assessed whether baseline renal function or EF modified the effect of therapy on renal outcomes. At randomization, eGFR was 68 ± 20 ml/min/1.73 m2 in PARADIGM-HF and 63 ± 19 ml/min/1.73 m2 in PARAGON-HF. The composite renal outcome occurred in 70 of 6594 patients (1.1%) in the sacubitril/valsartan group and in 123 of 6601 patients (1.9%) in the valsartan or enalapril group (hazard ratio 0.56, 95% confidence interval [CI] 0.42-0.75; p < 0.001). The mean eGFR change was -1.8 (95% CI -1.9 to -1.7) ml/min/1.73 m2 /year for the sacubitril/valsartan group, compared with -2.4 (95% CI -2.5 to -2.2) ml/min/1.73 m2 /year for the valsartan or enalapril group. The treatment effect on the composite renal endpoint was not modified by categories of baseline eGFR (p-interaction = 0.64), but was most pronounced in those with baseline EF between 30% and 60% (p-interaction = 0.001). CONCLUSIONS: In patients with heart failure, sacubitril/valsartan reduced the risk of serious adverse renal outcomes and slowed decline in eGFR, compared with valsartan or enalapril, independent of baseline renal function.

RESUMEN

Importance: In 2 trials enrolling patients with heart failure (HF) across the spectrum of ejection fraction (EF), dapagliflozin has been shown to reduce the rate of the composite of worsening HF events or death from cardiovascular (CV) causes. Objective: To examine the effects of dapagliflozin on cause-specific CV and non-CV mortality across the spectrum of EF. Design, Setting, and Participants: This was a participant-level, pooled, prespecified secondary analysis of data from the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure, or DAPA-HF trial (participant left ventricular EF [LVEF] ≤40%), and Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure, or DELIVER trial (participant LVEF >40%), to assess the effects of randomized treatment on cause-specific mortality. The trials assigned adjacent populations of patients with chronic HF, New York Heart Association class II-IV symptoms, and elevated natriuretic peptides to treatment with dapagliflozin (10 mg, once daily) or placebo. The primary outcome for each study was a composite of worsening HF events (hospitalization or urgent heart failure visits) or CV death. Clinical outcomes, including all deaths, were adjudicated as to cause by clinical end points committees blinded to treatment assignment. Intervention: Dapagliflozin vs placebo. Main Outcomes and Measures: The mode of death in relation to baseline EF was examined, as well as the effect of randomized treatment on cause-specific death in Cox regression models. Relationships with continuous EF were modeled using Poisson regression. Results: Of 11 007 patients in the pooled data set, there were 1628 deaths during follow-up (mean [SD] age, 71.7 [10.3] years; 1139 male [70.0%]). Of those who died, 872 (53.5%) were ascribed to CV deaths, 487 (29.9%) to non-CV deaths, and 269 (16.5%) to undetermined causes. Of CV deaths, 289 (33.1%; this represented 17.8% of total deaths) were due to HF, 441 (50.6%; 27.1% of total deaths) were sudden, 69 (7.9%; 4.2% of total deaths) were due to stroke, 47 (5.4%; 2.9% of total deaths) to myocardial infarction, and 26 (3.0%; 1.6% of total deaths) were due to other CV causes. The proportion of non-CV deaths was higher in those with higher EF. In the pooled population, across the spectrum of EF, treatment with dapagliflozin was associated with lower rates of CV death (hazard ratio [HR], 0.86; 95% CI, 0.75-0.98; P = .02), principally due to lower rates of sudden death (HR, 0.84; 95% CI, 0.70-1.01; P = .07) and HF death (HR, 0.88; 95% CI, 0.70-1.11; P = .30), with little difference in rates of death from stroke or MI. Conclusions and Relevance: In a pooled analysis of patients with HF in the DAPA-HF and DELIVER randomized clinical trials, across the full spectrum of LVEF, dapagliflozin significantly reduced risks of CV death with contributions from lower rates of sudden death and death from progressive HF.
