ABSTRACT
We evaluated the symptoms, changes in laboratory findings during the novel coronavirus disease (COVID-19) pandemic, and the effect of depression in patients with peritoneal dialysis (PD). This is an observational and cross-sectional study. All patients were asked to fill the clinical assessment form and Beck depression and anxiety inventory. Also, the last two laboratory evaluations during this period were examined. A total of 123 patients performing PD were included. None of the patients were diagnosed with COVID-19. In the total study population, parathyroid hormone (PTH), serum albumin, phosphorus and ferritin levels significantly elevated at the end of 97 ± 31 days. PTH and phosphorus levels remained stable in remote monitoring automated PD (RM-APD) group (p = 0.4 and p = 0.5), they tended to increase in continuous ambulatory PD group and significantly increased in automated PD group (p = 0.09 and p = 0.01 for PTH and p = 0.06 and p = 0.001 for phosphorus, respectively). Moderate to severe depression was associated with dyspnoea, weight gain more than 5 kg, fatigue, palpitation and increased anxiety. PD is a reliable and successful form of dialysis and can be safely administered even if hospital access is restricted. Also, RM-APD may be a better choice because of providing more stable bone-mineral metabolism. Moreover, evaluating depression and anxiety is essential for the accurate clinical assessment.

PURPOSE: We aimed to investigate the association between atherosclerotic changes in the common carotid artery (CA) and conjunctival and corneal calcification (CCC) in maintenance hemodialysis (MHD) patients. METHODS: Fifty eyes of MHD patients with the highest CCC scores were enrolled. CCCs were scored according to the method described by Tokuyama et al. The eyes with the highest CCC scores were selected for further analysis. According to their CCC scores, the patients were classified into 3 groups: mild (0-2 score), moderate (3-5), and severe (6-10 score). Atherosclerosis of the common CA was evaluated by determination of intima-media thickness (IMT), peak systolic (PSV) and end diastolic (EDV) flow velocities, pulsatility index, and resistive index values by using Doppler ultrasonography. RESULTS: The mean IMT of the CA was 0.61 ± 0.09 mm in the mild group, 0.82 ± 0.16 mm in the moderate group, and 1.21 ± 0.32 mm in the severe group (P < 0.001). The PSV and EDV were significantly higher in the severe group than in the mild and moderate groups (all, P < 0.001). The CCC score was positively correlated with the duration of hemodialysis, ocular surface disease index score, IMT, PSV, EDV, lymphocyte, calcium, and sedimentation rate. In multiple stepwise linear regression analysis, IMT was the best predictive factor for the CCC score (R = 0.812, ß = 9.526 ± 1.05, and P < 0.001). CONCLUSIONS: Our results suggest that chronic ocular ischemia due to atherosclerotic changes may have a role in the formation or progression of CCC in MHD patients.

Atherosclerotic cardiovascular disease is an important cause of mortality and morbidity in hemodialysis patients. Iron accumulation in arterial wall macrophages is increased in atherosclerotic lesions. Hepcidin is a key hepatic hormone regulating iron balance. It inhibits iron release from macrophages and iron absorption from enterocytes by binding and inactivating the cellular iron exporter ferroportin. The aim of this study is to investigate the relation of hepcidin-25, iron parameters, and atherosclerosis measured by carotid intima media thickness (CIMT) in hemodialysis patients. Eighty-two hemodialysis patients were enrolled in this cross-sectional study. Predialysis blood samples were centrifuged at 1500 g and 4°C for 10 minutes and stored at -80°C for the measurement of hepcidin-25. DRG hepcidin enzyme-linked immunosorbent assay kit was used for the measurement of hepcidin-25. Ultrasonographical B-mode imaging of bilateral carotid arteries was performed with a high-resolution real-time ultrasonography (Mindray DC7). Mean age of the study population was 57.90 ± 16.08 years and 43.9% were men. Total study population was grouped into two according to median value of hepcidin-25. There was no difference between groups with respect to age, dialysis vintage, and C-reactive protein. CIMT was found to be statistically significantly higher in low hepcidin-25 group. In correlation analysis, CIMT was found to be correlated with age (P < 0.01, R = 0.33) and hepcidin-25 (P < 0.01, R = 0.46). In linear regression analysis, age (ß = 0.31) and hepcidin-25 (ß = 0.44) were found to be the determinants of CIMT in hemodialysis patients. Our results implicate that hepcidin may take part in pathophysiology of atherosclerosis and cardiovascular disease in hemodialysis patients.
