- Aims: Chronic kidney disease (CKD) leads to impairment of immune cell function. Given the potential role of basophils in the pathogenesis of CKD, we aimed to study the basophil responsiveness towards microbial antigen exposure, judged as adhesion molecule expression and degranulation, in CKD patients on hemodialysis. Materials and methods: We selected markers linked to two crucial biological phases: the transmigration and degranulation processes, respectively. For the transmigration process, we selected the adhesion molecules CD11b, active CD11b epitope, and CD62L and for the degranulation process CD203c (piecemeal degranulation marker), CD63 (degranulation marker), and CD300a (inhibitory marker of degranulation). We measured basophil responsiveness after stimulation of different activation pathways in basophils using lipopolysaccharide (LPS), peptidoglycan (PGN), formyl-methyinoyl-leucyl-phenylalanine (fMLP), and anti-FceRI-ab. Results: The expression of CD63 in basophils following activation by fMLP was significantly higher in the patient group compared to matched healthy controls, but no differences were observed after activation by anti-Fc.RI. CD300a expression was significantly higher in patients following activation by fMLP and anti-Fc.RI, and the active epitope CD11b expression was significantly higher in patients after LPS activation. In addition, we found that CD62L was not shed from the cell surface after activation with LPS and fMLP. A slight downregulation was noted after activation with anti-Fc.RI in healthy controls. Conclusion: Together, these data demonstrate that basophil functions related to adhesion and degranulation are altered in CKD patients on hemodialysis, which indicates a potential role for the basophil in the pathogenesis of complications related to infections.

- © 2014 The Authors. Introduction: Left ventricular (LV) hypertrophy (LVH) and reduced LV function correlate with poor prognosis in patients with chronic kidney disease (CKD). Our aim is to investigate whether mild-to-moderate CKD is associated with cardiac abnormalities. Methods: Echocardiography, including tissue Doppler imaging, was performed in 103 patients with CKD at stages 2-3 and 4-5, and in 53 healthy controls. The systolic (s′) and diastolic myocardial velocity (e′), and the transmitral diastolic flow velocity (E) were measured, and E/e′ was calculated. Results: Patients with chronic kidney disease had higher mean E/e′ than controls (mean E/e′: controls 5·00 ± 1·23 versus CKD 4-5 6·36 ± 1·71, P < 0·001 and versus CKD 2-3 5·69 ± 1·47, P = 0·05), indicating altered diastolic function in the patients. The CKD groups showed lower longitudinal systolic function than controls, as assessed by atrio-ventricular plane displacement and s′ (mean s′: controls 11·5 ± 1·9 cm s < sup > -1 < /sup > versus CKD 4-5 10·4 ± 2·1 cm s < sup > -1 < /sup > , P = 0·03 and versus CKD 2-3 10·4 ± 2·1 cm s < sup > -1 < /sup > , P = 0·02). The prevalence of LVH was higher in patients with CKD than in controls (controls 13% versus CKD 4-5 37%, P = 0·006 and versus CKD 2-3 30%, P = 0·03). Conclusion: Alterations in systolic and diastolic myocardial function can be seen in mild-to-moderate CKD compared with controls, indicating that cardiac involvement starts early in CKD, which may be a precursor of premature cardiac morbidity.

- AIM: The study aimed to describe end of life for patients treated with maintenance haemodialysis as narrated by their close relatives.INTRODUCTION: Many patients undergoing haemodialysis are older, have several comorbidities and underestimated symptoms and are in their last year of life. To improve care, we need to know more about their end-of-life situation.DESIGN: Qualitative and descriptive.METHODS: Qualitative retrospective interviews were conducted with 14 close relatives of deceased haemodialysis patients (3-13 months after death). Data were analysed using qualitative content analysis. The study is ethically approved.FINDINGS: In the last months, a gradual deterioration in health with acute episodes necessitating hospital admissions was described. This involved diminishing living space and expressions of dejection, but also of joy. Three patterns emerged in the last weeks: uncertain anticipation of death as life fades away; awaiting death after haemodialysis withdrawal; and sudden but not unexpected death following intensive care. Findings show complexities of decisions on haemodialysis withdrawal.CONCLUSIONS: Different end-of-life patterns all involved increasingly complex care needs and existential issues. Findings show a need for earlier care planning. The identification of organisational factors to facilitate continuity and whole person care to meet these patients' specific care needs with their complex symptom burdens and comorbidities is needed. Findings indicate the need for integration of a palliative care approach in the treatment of patients in haemodialysis care.

- AIMS AND OBJECTIVES:To describe and elucidate the meanings of being a close relative of a severely ill family member treated with maintenance haemodialysis approaching the end of life.BACKGROUND:End-stage renal disease together with comorbidities, haemodialysis treatment and high mortality rates also affects the lives of close relatives, who report burdens and impaired quality of life. To improve care, more understanding is needed of close relatives' experiences during these patients' end of life.DESIGN:This study has a qualitative interpretative design.METHODS:Fourteen retrospective qualitative interviews were conducted with close relatives (aged 48-93 years) of deceased patients who had been treated with haemodialysis. The interview text was interpreted using a phenomenological hermeneutical method in three phases.RESULTS:The findings of the structural analysis were formulated as six themes: Striving to be supportive and helpful without doing harm to the ill person's self; Needing increasing strength and support; Balancing the will to help with one's own ongoing life; Increasing responsibility involving dilemmas; Striving for a good life together in the present and Living with awareness of death.CONCLUSIONS:Close relatives strive for balance and well-being accompanying their ill family member through the end of life. They are facing moral dilemmas and growing demands as their responsibility increases with the deterioration of their family member. Support from and interaction with the healthcare professionals is then of significance.RELEVANCE TO CLINICAL PRACTICE:Findings challenge healthcare professionals in haemodialysis settings to identify close relatives' individual resources and needs towards the patients' end of life. Healthcare professionals in haemodialysis settings need to offer close relatives opportunities to talk about the future and what may be expected at end of life, with or without haemodialysis. They should also contact the closest relative after the death as they may need confirmation and closure.

- BACKGROUND There is no consensus whether angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) should be used for secondary prevention in all or in only high-risk patients after an acute myocardial infarction (AMI).OBJECTIVES This study sought to investigate whether ACEI/ARB treatment after AMI is associated with better outcomes across different risk profiles, including the entire spectrum of estimated glomerular filtration rates.METHODS This study evaluated discharge and continuous follow-up data on ACEI/ARB use among AMI survivors (2006 to 2009) included in a large Swedish registry. The association between ACEI/ARB treatment and outcomes (mortality, myocardial infarction, stroke, and acute kidney injury [AKI]) was studied using Cox proportional hazards models (intention-to-treat and as treated).RESULTS In total, 45,697 patients (71%) were treated with ACEI/ARB. The 3-year mortality was 19.8% (17.4% of ACEI/ARB users and 25.4% of nonusers). In adjusted analysis, significantly better survival was observed for patients treated with ACEI/ARB (3-year hazard ratio: 0.80; 95% confidence interval: 0.77 to 0.83). The survival benefit was consistent through all kidney function strata, including dialysis patients. Overall, those treated with ACEI/ARB also had lower 3-year risk for myocardial infarction (hazard ratio: 0.91; 95% confidence interval: 0.87 to 0.95), whereas treatment had no significant effect on stroke risk. The crude risk for AKI was in general low (2.5% and 2.0% for treated and nontreated, respectively) and similar across estimated glomerular filtration rate categories but was significantly higher with ACEI/ARB treatment. However, the composite outcome of AKI and mortality favored ACEI/ARB treatment.CONCLUSIONS Treatment with ACEI/ARB after AMI was associated with improved long-term survival, regardless of underlying renal function, and was accompanied by low rates of adverse renal events.

- The cause of reduced exercise capacity (ExCap) in chronic kidney disease (CKD) is multifactorial. The aim of this study was to investigate determinants of aerobic ExCap in patients with mild to severe CKD not undergoing dialysis.We included 52 individuals with CKD stage 2-3, 47 with stage 4-5, and 54 healthy controls. Peak workload and peak heart rate (HR) were assessed by a maximal cycle exercise test. Cardiac function including stroke volume (SV) and vascular stiffness were evaluated by ultrasound at rest. Handgrip strength, body composition, haemoglobin level and self-reported physical activity were assessed.Peak workload (221±60, 185±59, 150±54 W for controls, CKD 2-3 and CKD 4-5 respectively), peak HR (177±11, 161±24, 144±31 beats/min) and haemoglobin level (14.2±1.2, 13.5±1.4, 12.2±1.3 g/dL) were all three significantly lower in CKD 2-3 than in controls, (p = 0.001, 0.001 and 0.03 respectively) and were even lower in stages 4-5 CKD than in CKD 2-3 (p = 0.01, 0.001 and <0.001 respectively). Resting SV and lean body mass did not differ between groups and handgrip strength was significantly lower only in CKD 4-5 compared to controls (p = 0.02). Peak workload was strongly associated with the systemic oxygen delivery factors: SV, peak HR and haemoglobin level. These three factors along with age, sex and height2 explained 82% of variation in peak workload. Peak HR contributed most to the variation; the peripheral variables handgrip strength and vascular stiffness did not improve the explanatory value in regression analysis.In this cross-sectional study of CKD patients not on dialysis, aerobic ExCap decreased gradually with disease severity. ExCap was associated mainly with systemic oxygen delivery factors, in particular peak HR. Neither muscle function and mass, nor vascular stiffness were independent determinants of aerobic ExCap in this group of CKD patients.
