Background: Etiologies for acute kidney injury (AKI) vary by geographic region and socioeconomic status. While considerable information is now available on AKI in the Americas, Europe and China, large comprehensive epidemiologic studies of AKI from Southeast Asia (SEA) are still lacking. The aim of this study was to investigate the rates and characteristics of AKI among intensive care unit (ICU) patients in Thailand., Methods: We conducted the largest prospective observational study of AKI in SEA. The data were serially collected on the first 28 days of ICU admission by registration in electronic web-based format. AKI status was defined by full Kidney Disease: Improving Global Outcome criteria. We used AKI occurrence as the clinical outcome and explored the impact of modifiable and non-modifiable risk factors on the development and progression of AKI., Results: We enrolled 5476 patients from 17 ICU centres across Thailand from February 2013 to July 2015. After excluding patients with end-stage renal disease and those with incomplete data, AKI occurred in 2471 of 4668 patients (52.9%). Overall, the maximum AKI stage was Stage 1 in 7.5%, Stage 2 in 16.5% and Stage 3 in 28.9%. In the multivariable adjusted model, we found that older age, female sex, admission to a regional hospital, medical ICU, high body mass index, primary diagnosis of cardiovascular-related disease and infectious disease, higher Acute Physiology and Chronic Health Evaluation II, non-renal Sequential Organ Failure Assessment scores, underlying anemia and use of vasopressors were all independent risk factors for AKI development., Conclusions: In Thai ICUs, AKI is very common. Identification of risk factors of AKI development will help in the development of a prognostic scoring model for this population and should help in decision making for timely intervention, ultimately leading to better clinical outcomes., (© The Author(s) 2019.

Background: Recently, in the first hemodiafiltration (HDF) experience report from South East Asia (SEA), we reported a 3-year prospective study demonstrating the various short-term benefits of high-efficiency online HDF (OL-HDF) over high-flux hemodialysis (HD). Very few long-term survival reports of high-efficiency OL-HDF are available and the data are heterogeneous and incomplete., Objectives: The present historical cohort study was conducted to determine the long-term survival and outcome of high-efficiency OL-HDF-treated patients., Methods: Sixty-six high-efficiency OL-HDF treated patients at a center in SEA were included in the study. The prescription included blood and dialysis fluid flow rates of 400 and 800 mL/min, respectively. The post- or pre-dilution substitution fluid of 100 or 200 mL/min, respectively, was prescribed., Results: Of 66 HDF patients, whose age was 57.4 ± 14.0 years, there were 38 (58%) females. The majority of comorbidity was diabetes (36%). There were 33 (50%) incident HDF cases that were prescribed OL-HDF at the dialysis initiation and 33 (50%) prevalent HDF cases that were switched from HD to OL-HDF. The 1-, 3-, 5-, and 10-year survival rate were 95.1, 83.4, 77.7, and 61.8% respectively. The mean survival time was 8.99 ± 0.64 years. There were 15 transplantations and 15 deaths during this study periods. The 2 major causes of death were cardiovascular (33.3%) and infectious diseases (20%). Serum ferritin was the only parameter that correlated with mortality (HR 1.004, p = 0.005). There was comparable survival between incident and prevalent HDF cases. The survival after transplantation of a sub-group of patients who received kidney transplantation (KT) was not different from that of the overall HDF patients (p = 0.93)., Conclusions: High-efficiency OL-HDF could provide an excellent long-term survival nearly comparable to the KT sub-group., (© 2018 S.

Growing evidence suggests the superiority of on-line hemodiafiltration (HDF) compared with the conventional hemodialysis technique in many aspects; however, on-line HDF is still not used worldwide, including in Southeast Asia. The purpose of this study is to compare various clinical outcomes between on-line HDF and high-flux hemodialysis (HFHD). This was a single-center three-year prospective observational study that demonstrated the clinical parameters after switching from HFHD to on-line HDF in 22 HDF patients, whose average age was 58.1 +/- 13.3 years. The incidence of intradialytic undesired events, including hypotension, decreased and an apparent increase in appetite and an improvement in overall well-being were recorded by most patients after switching to on-line HDF. The data for dry weight, body mass index, and normalized protein nitrogen appearance, which represent nutritional status, showed a significant improvement while still maintaining a satisfactory albumin level. The adequacy in terms of urea reduction ratio significantly increased. The serum predialysis beta(2)-microglobulin levels were reduced by 25.7% from 31.1 +/- 3.1 to 23.1 +/- 4.8 mg/L (P < 0.05) at six months and remained constant during the three years of follow-up. The patients' lipid profile was well controlled, and the mean C-reactive protein value was still maintained in the normal range. In conclusion, our three-year experience showed that on-line HDF is a well-tolerated treatment with a lower incidence of intradialytic undesired events. The potential benefits may include the effective removal of higher molecular weight uremic toxins and an improved nutritional status, along with a low inflammatory state.
