The aim of this study was to evaluate the evolution of lupus activity in end-stage renal disease (ESRD) patients due to lupus nephritis and to determine the long-term prognosis. We reviewed the clinical courses of 45 patients with ESRD due to systemic lupus erythematosus (SLE). We analyzed the course of SLE following the onset of ESRD, with special attention to the clinical and serological manifestations, survival time on dialysis, and renal transplantation outcome. Disease activity was measured using the SLE Disease Activity Index (SLEDAI). Of the 45 patients, 21 patients were being treated with hemodialysis (HD), 11 were undergoing peritoneal dialysis (PD), and 13 underwent transplantation. Duration of follow- up was 53 +/- 29 months. The SLEDAI score on commencement of renal replacement therapy was not significantly different among the 3 groups (HD: 4.2 +/- 4.2, PD: 4.3 +/- 2.3, Transplant: 3.2 +/- 1.9). However, disease activity scored by follow-up maximal SLEDAI during dialysis or transplantation showed a significant increase after peritoneal dialysis (HD: 5.0 +/- 3.6, PD: 7.4 +/- 3.7, Transplant: 2.2 +/- 1.7, p < 0.05). When the individual changes in the maximal SLEDAI score were considered, a significant increase was apparent after peritoneal dialysis (p < 0.05), but not after either hemodialysis or renal transplantation. There was no significant difference in cumulative survival rate, and also in technique or graft survival rates of the 3 groups. Among the variables tested, follow-up maximal SLEDAI score was the only significant factor associated with patient survival (odds ratio: 1.15, p < 0.05). The incidence (36% versus 19%) of high disease activity was greater, but not significantly, in the peritoneal dialysis group, as compared to the hemodialysis group. Clinical activity of SLE was apparent in 65% of patients in the first year of dialysis, but none showed any activity after the third year of dialysis. We found that although lupus disease activity declined after patients progressed to ESRD, lupus disease activity still affected patients' survival. An incremental increase in postdialysis lupus activity was not uncommon, especially during the first one year of dialysis. During the follow-up period, maximal SLEDAI score increased significantly after peritoneal dialysis. However, the long-term prognosis was not significantly different according to the treatment modality.

OBJECTIVETo investigate the epidemiological profile of acute kidney injury (AKI) in the Chinese critical patients.
METHODSThe hospitalization data and serum creatinine data of critically ill adult patients were collected from 9 regional central hospitals across China in 2013. Kidney Disease Improving Global Outcomes (KDIGO 2012) criteria was used to define and stage AKI. The demographic characteristics of the patients, comorbidities, stage of AKI, in-hospital outcomes and risk factors were retrospectively analyzed.
RESULTSOf the total of 14 305 critically ill patients included in the study, 4298 (30.04%) were identified to have AKI, including 2240 (52.1%) in stage 1, 845 (19.7%) in stage 2, and 1213 (28.2%) in stage 3. The in-hospital mortality rate was 16.7% (716/4298) and the odds ratio for death was 7.59 (95%CI 6.54-8.79, P<0.001). The length of hospital stay, daily cost, and mortality rate were associated with the stage of AKI. Multivariate analysis identified chronic kidney disease (OR=5.45, 95%CI: 4.71-6.32, P<0.001), extra-renal organ failure (OR=12.57, 95%CI: 11.24-14.07, P<0.001), shock (OR=2.44, 95%CI: 2.01-2.96, P<0.001) and cardiac surgery (OR=5.96, 95%CI: 5.16-6.87, P<0.001) as the independent risk factors for AKI. Only 5.4% of the AKI patients whose serum creatinine change met the KDIGO criteria during hospitalization received the diagnosis of AKI upon discharge.
CONCLUSIONAKI is common in critically ill patients and associated with high mortality rates and poor outcomes. The stage of AKI is related with the in-hospital outcomes of the patients. Chronic kidney disease, extra-renal organ failure, shock and cardiac surgery are the major risk factors for AKI in these patients. Missed diagnosis occurs in most of the AKI cases, which urges more awareness of the condition in the critically ill patients during hospitalization.

BACKGROUND/AIMS: Diastolic dysfunction occurs frequently in patients with chronic kidney disease (CKD) and is associated with heart failure (HF) or mortality. We investigated whether the ratio of early diastolic mitral inflow velocity to early diastolic mitral annulus velocity (E/e' ratio), estimated using tissue Doppler imaging, has prognostic value for cardiovascular morbidity and all-cause mortality in patients with CKD. METHODS: For 186 patients with CKD of stages III to V, we obtained echocardiograms with tissue Doppler imaging. A 5-year follow-up of 136 patients was performed based on hospital records and telephone interviews. The enrolled patients (79 males and 57 females) were categorized into the following CKD subgroups: stage III (n = 25); stage IV (n = 22); and stage V (n = 89). RESULTS: The average follow-up period was 30.45 months and the mean age of the patients was 61.13 years. The mortality rate after 5 years was 60.0%. The causes of death were: sepsis, 21.9%; HF, 16.2%; and sudden death, 15.2%. Age (p = 0.000), increased C-reactive protein level (p = 0.018), and increased E/e' ratio (p = 0.048) were found to correlate with mortality. Age (p = 0.000), decreased ejection fraction (p = 0.003), and increased E/e' ratio (p = 0.045) correlated with cardiovascular event. CONCLUSIONS: The E/e' ratio can predict mortality and cardiovascular events in patients with CKD who have diastolic dysfunction.

5.The Effect of Residual Renal Function at the Initiation of Dialysis on Patient Survival.
The Korean Journal of Internal Medicine 2009;24(1):55-62
BACKGROUND/AIMS: The optimal time point for initiating renal replacement therapy in patients with end-stage renal disease remains controversial. The primary objective of our study was to determine the effects of residual renal function at the beginning of renal replacement therapy on the mortality of patients with end-stage renal disease. METHODS: We retrospectively studied the clinical outcomes in patients (n=210) with end-stage renal disease who underwent renal replacement therapy at our hospital between 2000 and 2005; all patients were followed for more than 1 year. We used the Modification of Diet in Renal Disease equation to estimate residual renal function. RESULTS: Of the 210 patients who received renal replacement therapy, 108 were treated with hemodialysis and 102 were treated with peritoneal dialysis. Thirty-three patients died, and the mean survival period was 37.3+/-17.7 months. The survival rates were compared based on the estimated glomerular filtration rate; no difference in survival rates was observed (p=0.27). Subgroup analysis in the hemodialysis group showed that patients who began chronic dialysis at a lower estimated glomerular filtration rate had higher mortality rates (p<0.05); patients treated with peritoneal dialysis showed no significant difference in mortality rate (p=0.50). CONCLUSIONS: Although there was no difference in the mortality rate based on residual renal function, hemodialysis patients with a lower estimated glomerular filtration rate showed a higher mortality rate than those with a higher estimated glomerular filtration rate.

This study evaluated the significance of aortic calcification index (ACI), an estimate of abdominal aortic calcification by plain abdominal computed tomography (CT), in terms of left ventricular (LV) diastolic dysfunction, mortality, and nonfatal cardiovascular (CV) events in chronic hemodialysis patients. Hemodialysis patients who took both an abdominal CT and echocardiography were divided into a low-ACI group (n = 64) and a high-ACI group (n = 64). The high-ACI group was significantly older, had a longer dialysis vintage and higher comorbidity indices, and more patients had a previous history of CV disease than the low-ACI group. The ACI was negatively correlated with LV end-diastolic volume or LV stroke volume, and was positively correlated with the ratio of peak early transmitral flow velocity to peak early diastolic mitral annular velocity (E/E' ratio), a marker of LV diastolic function. The E/E' ratio was independently associated with the ACI. The event-free survival rates for mortality and nonfatal CV events were significantly lower in the high-ACI group compared with those in the low-ACI group, and the ACI was an independent predictor for all-cause deaths and nonfatal CV events. In conclusion, ACI is significantly associated with diastolic dysfunction and predicts all-cause mortality and nonfatal CV events in hemodialysis patients.
