BACKGROUND: Non-adherence and comorbidities are prevalent among hemodialysis patients and are associated with increased mortality and financial burden. We aimed to investigate the influence of major coping strategies (CSs) on non-adherence and comorbidities in hemodialysis patients. METHODS: A total of 49 patients were enrolled. We collected participant data including CS measured by a Korean version of the ways of coping questionnaire (K-WCQ), comorbidities measured by age-adjusted Charlson comorbidity index (CCI), and adherence measured by the 8-item Morisky medication adherence scale (MMAS-8). RESULTS: Regarding major CS, 61.2% of participants reported use of support-seeking CS (SUP group), 14.3% reported use of problem-focused CS (PRO group), and 24.5% reported use of hopeful-thinking CS (HOP group). The mean MMAS-8 score was higher in the PRO group than in the HOP group (P = 0.024). The mean CCI score was lower in the PRO group than in the HOP group (P = 0.017). In the HOP group, the severity of somatic symptoms was positively correlated with the scores for the emotion-focused CS subscale (r = 0.39, P = 0.029) and the hopeful-thinking CS subscale (r = 0.38, P = 0.036) of the K-WCQ. The level of life satisfaction positively correlated with the score for the problem-focused CS subscale in the HOP group (r = 0.40, P = 0.027). CONCLUSION: We should pay more attention to the CSs of hemodialysis patients and provide interventions that promote problem-focused CSs, especially for nonadherent patients with high comorbidity rates who mainly use a hopeful-thinking CS.

Conventional hemodialysis, which is based on the diffusive transport of solutes, is the most widely used renal replacement therapy. It effectively removes small solutes such as urea and corrects fluid, electrolyte and acid-base imbalance. However, solute diffusion coefficients decreased rapidly as molecular size increased. Because of this, middle and large molecules are not removed effectively and clinical problem such as dialysis amyloidosis might occur. Online hemodiafiltration which is combined by diffusive and convective therapies can overcome such problems by removing effectively middle and large solutes. Online hemodiafiltration is safe, very effective, economically affordable, improving session tolerance and may improve the mortality superior to high flux hemodialysis. However, there might be some potential limitations for setting up online hemodiafiltaration. In this article, we review the uremic toxins associated with dialysis, definition of hemodiafiltration, indication and prescription of hemodiafiltration and the limitations of setting up hemodiafiltration.

BACKGROUND: Although patients with end-stage renal disease (ESRD) experience excess mortality compared with the general population, the standardized mortality ratio (SMR) for Korean patients on dialysis has not yet been investigated. In this study, we evaluated the SMR among all Korean ESRD patients on maintenance ialysis in 2009 and 2010, and compared it according to age categories, sex, and dialysis modality. METHODS: We used data from all patients on maintenance dialysis between January 1, 2009 and December 31, 2010 in Korea using the database of the Korean Health Insurance Review and Assessment Service, and the SMR was determined by calculating of the ratio between the number of actual deaths and expected deaths. RESULTS: A total of 45,568 patients in 2009 and 48,170 patients in 2010 were included in the analysis. The overall age- and sex-adjusted SMR was 10.3 [95% confidence interval (CI), 10.0-10.6] in 2009 and 10.9 (95% CI, 10.7-11.2) in 2010. The SMR for females was much higher than for males. The SMR gradually decreased with increasing age groups. The overall SMR for maintenance hemodialysis patients was lower than that of peritoneal dialysis patients. CONCLUSION: The SMR among Korean ESRD patients is likely to be higher than in other countries. Further evaluation is needed to attempt to improve the outcomes.

Protein and energy malnutrition are common in dialysis patients. Nutritional assessment is of great importance because undernutrition has been shown to be associated with increased morbidity and mortality in both hemodialysis and peritoneal dialysis. To validate subjective global assessment(SGA) in dialysis patients we compared subjective global assessment with objective measurements(anthropometry, bioelectrical impedance, biochemical measurements) in 54 chronic hemodialysis patients. We divided patients into three groups(SGA1, SGA2, SGA3) according to modified subjective global assessment performed by an observer. Body weight, %IBW, BMI, TSF, MAC, nPCR were different significantly among three groups. SGA was related objective measurements such as body weight, %IBW, BMI, %Fat, TSF, MAC, nPCR(p<0.001). Multiple regression analysis showed that the relationship of SGA(as a dependent variable) with objective measurement(covariate) was stronger(multiple r=0.789, R2=60%) than the relationship found with univariate analysis. In other words, since no single objective method can be considered a gold standard of nutritional assessment, our data show that subjective global assessment is a clinically adequate method for assessing nutritional status in maintenance hemodialysis patients.
