The Association of Frailty With Long-Term Outcomes in Patients With Acute Respiratory Failure Treated With Noninvasive Ventilation
The objective of this study was to investigate the prevalence and impact of frailty on mortality in patients with acute respiratory failure (ARF) treated with noninvasive ventilation (NIV). This was a single-center, prospective study of patients who developed ARF (irrespective of etiology) and were treated with NIV support. Frailty was assessed using the Clinical Frailty Scale (CFS). We modeled the relationship of CFS with one-year mortality using Cox proportional hazards regression, adjusting for other clinical and demographic characteristics. Of the 166 patients enrolled, 48% had moderate to severe frailty. These patients were more likely to be female (67% versus 33%) and on oxygen therapy at home (46% versus 28%). The median CFS score was 5 (interquartile range (IQR): 5-6). Moderate to severe frailty was associated with a 60% higher risk of one-year mortality (hazard ratio (HR): 1.63, 95% confidence interval (CI): 1.15-2.31). Frailty assessment may identify patients in need of ventilatory support who are at increased risk of mortality and may be an important factor to consider when discussing goals of care in this vulnerable population.

TcR alpha beta-depleted haploidentical transplantation results in adult acute leukemia patients
Introduction: The use of alpha beta+ T-cell-depleted grafts is a novel approach to prevent graft failure, graft-versus-host disease (GVHD), and non-relapse mortality (NRM) in patients undergoing haploidentical hematopoietic stem cell transplantation
The longitudinal evolution of post-COVID-19 outcomes among hemodialysis patients in Turkey
Introduction: Hemodialysis (HD) patients have increased risk for short-term adverse outcomes of COVID-19. However, complications and survival at the post-COVID-19 period have not been published extensively.Methods: We conducted a national, multicenter observational study that included adult maintenance HD patients recovered from confirmed COVID-19. A control HD group without COVID-19 was selected from patients in the same center. We investigated the characteristics and outcomes in the follow-up of HD patients and compare them with the non-COVID-19 group.Results: A total of 1223 patients (635 patients in COVID-19 group, 588 patients in non-COVID-19 group) from 47 centers were included in the study. The patients' baseline and HD characteristics were almost similar. The 28th-day mortality and mortality between 28th day and 90th day were higher in the COVID-19 group than non-COVID-19 group (19 [3.0%] patients vs. none [0%]; 15 [2.4%] patients vs. 4 [0.7%] patients, respectively). The presence of respiratory symptoms, rehospitalization, need for home oxygen therapy, lower respiratory tract infection, and arteriovenous (AV) fistula thrombosis was significantly higher in the COVID-19 group in both the first 28 days and between 28 and 90 days. In the multivariable analysis, age (odds ratio [OR] [95% CI]: 1.029 [1.004-1.056]), group (COVID-19 group vs. non-COVID-19 group) (OR [95% CI]: 7.258 [2.538-20.751]), and vascular access type (tunneled catheter/AV fistula) (OR [95% CI]: 2.512 [1.249-5.051]) were found as independent parameters related to 90-day mortality.Conclusion: In the post-COVID-19 period, maintenance HD patients who have had COVID-19 have increased rehospitalization, respiratory problems, vascular access problems, and high mortality compared with the non-COVID-19 HD patients
The longitudinal evolution of post–COVID-19 outcomes among hemodialysis patients: A nationwide multicentre controlled study
BACKGROUND AND
AIMS:
Haemodialysis (HD) patients are at increased risk for adverse short-term consequences of COVID-19. In this study, we investigated the characteristics of chronic HD patients in the post-COVID-19 period and compared them with the control group.
METHOD:
We conducted a national multicentre observational study involving adult chronic HD patients recovering from COVID-19. The control HD group was selected from patients with similar characteristics who did not have COVID-19 in the same center. SARS-CoV-2 RT-PCR negative patients and patients in the active period of COVID-19 were not included.
RESULTS:
A total of 1223 patients (635 COVID-19 groups, 588 control groups) were included in the study from the data collected from 47 centres between 21 April 2021 and 11 June 2021. The patients' baseline demographics, comorbidities, medications, HD characteristics and basic laboratory tests were quite similar between the groups (Table 1). 28th-day mortality and between 28th day and 90th day mortality were higher in the COVID-19 group than in the control group [19 (3.0%) patients and 0 (0%) patients;15 (2.4%) patients and 4 (0.7%) patients, respectively]. Presence of respiratory symptoms, rehospitalization, need for home oxygen therapy, lower respiratory tract infection and A-V fistula thrombosis were significantly higher in the COVID-19 group in the first 28 days of illness and between 28 and 90 days. Mortality was significantly associated with preexisting COVID-19, age, current smoking, use of tunneled HD catheter, persistence of respiratory symptoms, rehospitalization, need for home oxygen support, presence of lower respiratory tract infection within 28 days and persistence of respiratory symptoms.
CONCLUSION:
In the post-COVID-19 period, mortality, rehospitalization, respiratory problems and vascular access problems are higher in maintenance HD patients who have had COVID-19 compared to control HD patients. (Table Presented)
Mortality analysis of COVID-19 infection in chronic kidney disease, haemodialysis and renal transplant patients compared with patients without kidney disease: a nationwide analysis from Turkey
Background. Chronic kidney disease (CKD) and immunosuppression, such as in renal transplantation (RT), stand as one of the established potential risk factors for severe coronavirus disease 2019 (COVID-19). Case morbidity and mortality rates for any type of infection have always been much higher in CKD, haemodialysis (HD) and RT patients than in the general population. A large study comparing COVID-19 outcome in moderate to advanced CKD (Stages 3-5), HD and RT patients with a control group of patients is still lacking. Methods. We conducted a multicentre, retrospective, observational study, involving hospitalized adult patients with COVID-19 from 47 centres in Turkey. Patients with CKD Stages 3-5, chronic HD and RT were compared with patients who had COVID-19 but no kidney disease. Demographics, comorbidities, medications, laboratory tests, COVID-19 treatments and outcome [in-hospital mortality and combined in-hospital outcome mortality or admission to the intensive care unit (ICU)] were compared. Results. A total of 1210 patients were included [median age, 61 (quartile 1-quartile 3 48-71) years, female 551 (45.5%)] composed of four groups: Control (n = 450), HD (n = 390), RT (n = 81) and CKD (n = 289). The ICU admission rate was 266/ 1210 (22.0%). A total of 172/1210 (14.2%) patients died. The ICU admission and in-hospital mortality rates in the CKD group [114/289 (39.4%); 95% confidence interval (CI) 33.9-45.2; and 82/289 (28.4%); 95% CI 23.9-34.5)] were significantly higher than the other groups: HD = 99/390 (25.4%; 95% CI 21.3-29.9; P<0.001) and 63/390 (16.2%; 95% CI 13.0-20.4; P<0.001); RT = 17/81 (21.0%; 95% CI 13.2-30.8; P = 0.002) and 9/81 (11.1%; 95% CI 5.7-19.5; P = 0.001); and control = 36/450 (8.0%; 95% CI 5.8-10.8; P<0.001) and 18/450 (4%; 95% CI 2.5-6.2; P<0.001). Adjusted mortality and adjusted combined outcomes in CKD group and HD groups were significantly higher than the control group [hazard ratio (HR) (95% CI) CKD: 2.88 (1.52- 5.44); P = 0.001; 2.44 (1.35-4.40); P = 0.003; HD: 2.32 (1.21- 4.46); P = 0.011; 2.25 (1.23-4.12); P = 0.008), respectively], but these were not significantly different in the RT from in the control group [HR (95% CI) 1.89 (0.76-4.72); P = 0.169; 1.87 (0.81-4.28); P = 0.138, respectively]. Conclusions. Hospitalized COVID-19 patients with CKDs, including Stages 3-5 CKD, HD and RT, have significantly higher mortality than patients without kidney disease. Stages 3-5 CKD patients have an in-hospital mortality rate as much as HD patients, which may be in part because of similar age and comorbidity burden. We were unable to assess if RT patients were or were not at increased risk for in-hospital mortality because of the relatively small sample size of the RT patients in this study
