There was a significant association between UACR and UPCR in patients with CKD. Characteristics of patients, renal function, and co-morbidities all affected UACR, UPCR, and UAPR.

Background It is well known that the quality of life of patients with chronic kidney disease can be improved by dialysis. While previous studies have used retrospective designs and adhered to a standard target prescribed by clinical guidelines, our study prospectively investigates the association between the adequacy of peritoneal dialysis (PD) and measures of nutritional status on quality-of-life domains in a cohort of incident PD patients. Methods It was a prospective 6-month observational study. Eighty incident PD participants who were treated in a hospital-based PD center were enrolled. The period of enrollment was January 2009–June 2010; follow-up continued until December 2010. PD adequacy indices, including Kt/V urea, weekly Ccr (WCcr), measures of nutritional status (albumin, BMI), and nPCR were measured at 1 month and 6 months after PD initiation. SF-36 health survey questionnaires were used to measure the quality of life. The outcomes were used to measure the changes in the domains of the SF-36 after 6 months of PD therapy. Results Seventy-seven incident patients who underwent PD for 6 months were included in the study. The mean age was 47.3 years, and the male-to-female ratio was 38:39. A peritoneal Kt/V urea value of 1.2, which was also the baseline cutoff value, was found to have the highest influence on SF-36 domains. Patients with baseline peritoneal Kt/V urea value of <1.2 showed improvement in the physical functioning and role limitation of physical functioning components after 6 months of PD. In contrast, patients with baseline peritoneal Kt/V urea values of ≥1.2 showed remarkable improvement in the general health, physical functioning, role limitation caused by physical problems, and bodily pain components. However, the trend of improvement decreased in patients with baseline nPCR of <1.2. Baseline renal WCcr did not influence the improvement in the SF-36 domains. Limitations A small cohort and a short observation period. Conclusions The baseline level of peritoneal Kt/V urea affected the components of the quality of life after PD initiation. In contrast, a lower baseline nPCR level was associated with deterioration in the quality of life after PD therapy.

The aims of this study were to investigate the prevalence of sleep disorders in patients with end-stage renal disease (ESRD), and to assess the effect of dialysis schedule on sleep quality and the presence of daytime symptoms. We prospectively selected 150 long-term hemodialysis (HD) patients in three groups (morning, afternoon, and evening dialysis) and gave them a sleep questionnaire, the Epworth sleepiness scale and the Pittsburgh sleep quality index. Snoring was the most common complaint (56%), followed by insomnia (38%) and restless legs syndrome (22.7%). The evening dialysis group experienced more sleep time in bed (P = 0.02), required less hypnotic medication (P = 0.049), had fewer daytime symptoms (P < 0.01), and experienced less daytime sleepiness (P = 0.034). Our study confirms the high prevalence of sleep disorders in ESRD patients, and indicates a beneficial effect of evening HD on sleep quality and reduction of daytime symptoms.

Eosinophilia is not an uncommon finding in chronic dialysis patients. It is usually benign in nature although definite pathogenesis is unknown. We have encountered a young uremic Chinese adult who developed Kimura’s disease after being on maintenance hemodialysis for about 3 years. Asymptomatic eosinophilia had been noted for 1 year and 8 months prior to the development of progressively enlarged neck masses, which leads to the diagnosis of Kimura’s disease. In contrast to most cases, eosinophilia was first noticed before the neck masses appeared. There is often a close correlation between Kimura’s disease and glomerular disease, where renal involvement is considered as a systemic manifestation. However, we do not have strong evidence to support this relationship between terminal renal failure and Kimura’s disease in this patient. To our knowledge, our patient is the first reported case of Kimura’s disease occurring in chronic hemodialysis patients. Eosinophilia persisted for nearly 2 years before the neck mass developed and recurred after the excision. Besides, our patient also demonstrated a chronic and recurrent course typical of Kimura’s disease.

Among Chinese subjects with T2DM, our findings suggested that the CKD-EPI Chinese T2DM equation best predicted all-cause mortality, and relative to the CKD-EPI equation, conferred improved discrimination and reclassification.
