The association of low serum magnesium levels with frailty among hemodialysis patients

Frailty is common among hemodialysis patients and is associated with mortality and fractures. Hypomagnesemia is also known to be a risk factor for mortality and fractures and has been shown to be significantly associated with muscle performance indexes. However, little is known about the association between hypomagnesemia and frailty. We enrolled 339 outpatients who underwent hemodialysis and assessed frailty using the Clinical Frailty Scale (CFS), a 7-point subjective assessment tool based upon clinical judgment. We examined the association between serum magnesium levels and frailty evaluated using the CFS. The median CFS score was 3 points, and 49 (14.5%) patients had frailty (CFS score ≥ 5). In multiple regression analysis, serum magnesium levels were independently associated with increased CFS scores (β = - 0.126, P = 0.005) adjusted for age, body mass index, diabetes, cardiovascular diseases, prevalent fractures, serum albumin and C-reactive protein. The adjusted odds ratio for frailty was 2.85 [95% confidence interval (CI) 1.23-6.97, P = 0.014] in the lower serum magnesium group categorized based on the median value. Furthermore, with regard to model discrimination, adding serum magnesium levels to the established risk factors significantly improved net reclassification (0.520, P < 0.001) and integrated discrimination (0.023, P = 0.031). Lower serum magnesium levels may be associated with the severity and definition of frailty independent of well-known risk factors.

Peritoneal Dialysis Failure and its Impact on Holistic Kidney Care: A Case Report

Introduction

Peritonitis remains the primary cause of treatment failure among patients with end-stage kidney disease on continuous ambulatory peritoneal dialysis. However, detailed case analyses illustrating the application of current research in clinical practice remain scant. This case report aimed to elucidate the roles of dialysis nurses in a hospital setting in the management of a 62-year-old male patient with a history of kidney failure secondary to amyloidosis.

Case Presentation

The patient was diagnosed with continuous ambulatory peritoneal dialysis-associated peritonitis.

Management and Outcomes

Dialysis nurses applied evidence-based practices in the management of the patient’s exit-site infection, imbalanced nutrition, and psychosocial concerns. The patient was discharged after 7 days, with a comprehensive treatment regimen, including an individualized peritoneal dialysis protocol adjusted to his daily schedules, education on self-care techniques, and continual nutritional management to prevent recurrence and improve his overall health. This case report shows that admissions for continuous ambulatory peritoneal dialysis-associated peritonitis require evidence-based nursing interventions specific to, and geared toward, each patient’s prioritized health problems.

Discussion

Peritonitis cases are preventable with appropriate nursing interventions that can lower the chance of treatment failure and long-term impact caused by an abrupt switch to hemodialysis. To successfully manage patients with continuous ambulatory peritoneal dialysis-associated peritonitis, dialysis nurses should appreciate the intricacies of the analyses underpinning their professional practices in promoting the patient’s self-care techniques.

Health-related quality of life on combination therapy with peritoneal dialysis and hemodialysis in comparison with hemodialysis and peritoneal dialysis: A cross-sectional study

Background:

The health-related quality of life (HRQOL) of dialysis patients has not been well examined, especially in combination therapy with peritoneal dialysis and hemodialysis (PD+HD) patients. We compared the HRQOL of PD+HD patients with that of HD and PD patients.

Methods:

A multicenter, cross-sectional study was conducted on 36 PD+HD, 103 HD, and 90 PD patients in Japan who completed the Kidney Disease Quality of Life Short Form 36, version 1.3. HRQOL scores were summarized into physical- (PCS), mental- (MCS), role/social- (RCS), and kidney disease component summaries (KDCS).

Results:

Of the PD+HD patients, 31 (86%) transferred from PD and 5 (14%) transferred from HD. They had the longest dialysis vintage and the smallest urine volume. PCS, MCS, and KDCS HRQOL scores of PD+HD patients were comparable with those of HD and PD patients. However, the RCS score for PD+HD was significantly higher than that for HD ( p = 0.020) and comparable with that for PD. PD+HD and PD were associated with significantly higher RCS scores than HD after adjusting for age, gender, diabetic nephropathy, dialysis vintage, ischemic heart disease, and peripheral arterial disease.

Conclusions:

For RCS, HRQOL in PD+HD patients was better than that in HD and comparable with that in PD patients, whereas the PCS, MCS, and KDCS HRQOL scores of PD+HD patients were comparable with those of HD and PD patients.
