Purpose: Decreased quality of life, anxiety, depression, and other negative psychosocial factors in autosomal dominant polycystic kidney disease (ADPKD) may lead to the patient's attitudes that reduce treatment effectiveness. We aimed to evaluate the relationship between the depression, anxiety, perceived social support, genetic psychosocial risk and quality of life levels, and chronic kidney disease (CKD) stage in ADPKD and to investigate the relationship between these variables/parameters and the dietary compliance that is an essential factor in the course of the disease., Methods: 100 ADPKD patients were enrolled in this cross-sectional study. EuroQol-5D-3L (EQ-5D-3L) health-related quality of life ındex, EuroQol-5D-3L visual analog scale (EQ-5D-3L VAS), multidimensional scale of perceived social support (MSPSS), patient health questionnaire (PHQ)-9, and genetic psychosocial risk ınstrument (GPRI) were applied to the patients., Results: There is a relationship with negative regression coefficient between the CKD stage and the total scores of the EQ-5D-3L and EQ-5D-3L VAS scales (p < 0.000 and β =  - 5.355, p < 0.000, and β =  - 8.394, respectively). There is a relationship with positive regression coefficient between the CKD stage and MSPSS total score and level (p < 0.000 and β = 0.364, p < 0.000 and β = 0.331, respectively). There is no relationship between the CKD stage and GPRI total score (p = 0.800). In addition, there is a relationship with positive regression coefficient between the dietary compliance and EQ-5D and EQ-5D VAS total scores (p = 0.006 and β = 2.687, p = 0.004 and β = 3.148, respectively). There is a relationship with negative regression coefficient between the dietary adherence and PHQ-9 total score and CKD stage (p = 0.003, p = 0.006, and β =  - 0.692, respectively)., Conclusion: As the CKD stage increases in the ADPKD patients, the quality of life decreases, whereas the level of anxiety and depression increases. It has been seen that the ADPKD patients with more depressive complaints have less dietary compliance. In this particular patient group, the early detection and treatment of psychosocial difficulties and the work to improve the quality of life that affect the course of the ADPKD may be as important as the medical treatment. To determine the needs of ADPKD patients with multiple physical and psychosocial difficulties and to perform appropriate interventions, we think that there is a necessity for a specific scale that evaluates these effective components together in the ADPKD process., (© 2022.

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., (© The Author(s) 2020.

Background: Cardiac troponins are specific and sensitive markers of myocardial damage. Troponin levels may increase without an obvious active cardiac disease in hemodialysis patients. In this study, we aimed to investigate the effect of a single hemodialysis session on echocardiographic parameters and cardiac enzyme levels, including cTn-I, creatine phosphokinase (CPK), and creatine kinase-MB (CK-MB)., Patients and Methods: Forty patients under chronic hemodialysis treatment enrolled in this prospective study. All the patients had a physical examination and underwent echocardiography before and after hemodialysis. cTn-I, CPK and CK-MB levels were also determined before and after hemodialysis in all patients., Results: Post-dialysis cTn-I levels were significantly higher compared to pre-dialysis levels (p = 0.03). cTn-I levels increased in 26 patients, did not change in 1 patient and decreased in 13 patients after hemodialysis when compared to the values determined before hemodialysis. There was no significant increase in CPK and CK-MB levels after dialysis. Statistically significant changes were detected in the end-systolic diameter of the left ventricle, end-diastolic diameter of left ventricle, ejection fraction, diameter of the left atrium, diameter of the right atrium, pulmonary artery pressure and end-diastolic diameter of the right ventricle. However, there was no significant relation between these echocardiographic changes and ultrafiltration volume, blood flow rate, age, and gender., Conclusions: Hemodialysis leads to an increase in cTnI levels. However, the effect of increased cTnI levels on survival rates in hemodialysis patients with underlying coronary artery disease has not yet been determined. Prospective multi-center studies with large sample size are required to clarify this issue.
