RESUMEN
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.

BACKGROUND: The incidence of chronic kidney disease (CKD) is high in the Northeast Thailand compared to other parts of the country. Therefore, a broad program applying all levels of care is inevitable. This paper describes the results of the first year trial of the Chronic Kidney Disease Prevention in the Northeast Thailand (CKDNET), a quality improvement project collaboratively established to curb CKD. METHODS: We have covered general population, high risk persons and all stages of CKD patients with expansive strategies such as early screening, effective CKD registry, prevention and CKD comprehensive care models including cost effectiveness analysis. RESULTS: The preliminary results from CKD screening in general population of two rural sub-districts show that 26.8% of the screened population has CKD and 28.9% of CKD patients are of unknown etiology. We have established the CKD registry that has enlisted a total of 10.4 million individuals till date, of which 0.13 million are confirmed to have CKD. Pamphlets, posters, brochures and other media of 94 different types in the total number of 478,450 has been distributed for CKD education and awareness at the community level. A CKD guideline that suits for local situation has been formulated to deal the problem effectively and improve care. Moreover, our multidisciplinary intervention and self-management supports were effective in improving glomerular filtration rate (49.57 versus 46.23 ml/min/1.73 m2; p < 0.05), blood pressure (129.6/76.1 versus 135.8/83.6 mmHg) and quality of life of CKD patients included in the program compared to those of the patients under conventional care. The cost effectiveness analysis revealed that lifetime cost for the comprehensive health services under the CKDNET program was 486,898 Baht compared to that of the usual care of 479,386 Baht, resulting in an incremental-cost effectiveness ratio of 18,702 Baht per quality-adjusted life years gained. CONCLUSION: CKDNET, a quality improvement project of the holistic approach is currently applying to the population in the Northeast Thailand which will facilitate curtailing of CKD burden in the region.

BACKGROUND/AIMS: We aimed to define the dosing and risk factors for death in patients undergoing twice-weekly hemodialysis. METHODS: A prospective multi-center cohort study was conducted with one-year observation. Patients treated with twice- or thrice-weekly hemodialysis were identified. Death and first admission were the outcomes. spKt/V was a factor of interest. RESULTS: We enrolled 504 twice-weekly and 169 thrice-weekly hemodialysis patients. The mean weekly values of spKt/V in the two groups were 3.4 and 5.1. The one-year survival rate and times to hospitalization were similar in both groups. The hazard ratios for death in higher spKt/V quartile was not associated with lower mortality, p = 0.70. The four significant predictors for death were serum albumin, HR = 2.6, current smoking, HR = 19.3, age, HR = 1.1, and the Index of Coexistent Disease [ICED], HR = 1.9. CONCLUSION: The effect of spKt/V on short-term mortality was not obvious in twice-weekly dialysis patients. Attention should be paid to patients who smoke, have hypoalbuminemia, are elderly, or have a high ICED.

INTRODUCTION: The impact of timing of hemodialysis (HD) for end-stage renal disease (ESRD) patients treated with twice-weekly HD remains unclear. We aimed to determine the effects of late initiation of HD on short-term mortality and hospitalization. METHODS: A multicenter cohort study was conducted in 11 HD centers in Northeastern Thailand (HEmodialysis Network of the NorthEastern Thailand study group). We recruited adult ESRD patients who were treated with twice-weekly HD for more than 3 months and had data on eGFR at HD initiation. Clinical and laboratory values at the time of recruitment were recorded. Late and early (eGFR at start <5 and >5 ml/min/1.73 m2 ) initiations were defined. Outcomes were disease-related death (excluding any accidental deaths) and first hospitalization. Data analysis was performed by multivariable cox-regression analysis. FINDINGS: A total of 407 patients who had data on eGFR at HD initiation (303 in late group and 104 in early group) were included for analysis. There were 56.8% male with a mean age of 55 years. During the 15.1 months of follow-up, there were 27 (6.6%) disease-related deaths. The 1-year survival rate was similar among late and early initiation groups. The incidence density of first hospitalization in the late group was significantly lower than those in the early group (HR adjusted, 0.63; 95% CI, 0.40-0.99, p = 0.047). Among 303 patients who were in the late start group, patients with diabetes had a higher mortality rate (HR, 3.49; 95% CI, 1.40-8.70, p = 0.007) when compared to non-diabetic patients. DISCUSSION: Early initiation of HD at eGFR >5 ml/min/1.73 m2 had no short-term survival benefit compared to the late group in ESRD patients treated with twice-weekly HD for at least 3 months in a resource-limited setting. A survival benefit from an early start of HD was found among diabetic patients.

AIM: The aim of this study was to present the clinical course and treatment outcomes of patients with acute kidney injury (AKI) after septic unsafe abortion. MATERIAL AND METHODS: Medical records of patients with AKI after septic unsafe abortion admitted at Khon Kaen Hospital between January 2003 and December 2009 were reviewed. RESULTS: Forty-four patients with an average age of 24.3 years were included and 25% were teenage girls. The most common method of induced abortion was transvaginal chemical injection (81.8%). One patient had a hysterectomy due to severe peritonitis and sepsis that was not responsive to medical treatment. AKI developed on day 4.5 ± 3.6 with the range of onset 1-14 days after induced abortion. Oliguric AKI was present in 70.4% of patients with the mean duration of oliguria of 7.4 ± 5 days. Seventeen patients required dialysis. The mortality rate was 9%. The average duration of recovery from AKI was 24.8 ± 16.6 days. CONCLUSIONS: Conservative treatment of AKI-related septic unsafe abortion was dialysis without hysterectomy. The treatment results were minimal morbidity and mortality. Conservative management may be a better alternative to hysterectomy for the treatment of septic unsafe abortion with AKI. However the current study was a retrospective study, and we were not able to obtain certain follow-up data, such as fertility outcomes after recovery. Therefore, further study of these issues should be considered.

PURPOSE: To determine the effects of modalities of renal replacement therapy (RRT) on the 30-d mortality and renal recovery in patients with acute kidney injury (AKI). MATERIALS AND METHODS: A multicenter cohort study was conducted in 17 hospitals from Thailand and Indonesia. We recruited patients who were admitted to the Intensive care unit and diagnosed with AKI. Relevant mode of RRT, as intermittent hemodialysis (IHD), continuous renal replacement therapy (CRRT), peritoneal dialysis (PD), or sustained low efficiency dialysis (SLED), was initiated as indicated. RESULTS: From 2844 patients with AKI, 449 cases (8.1%) received RRT. There were no significant differences in the 30-d mortality between those initially treated with CRRT, PD, and SLED compared to those treated with IHD. The renal recovery was similar for each RRT mode. The three independent factors of death were the primary diagnosis of kidney disease, higher APACHE II score, and non-renal SOFA score. Only 48 (10.7%) patients had been switched to another mode of RRT. CONCLUSIONS: All four modes of RRT (IHD, CRRT, PD, and SLED) are acceptable treatments for severe AKI and gave a similar survival rate.

BACKGROUND: TNF-like weak inducer of apoptosis (TWEAK) is a proinflammatory molecule that plays a key role in active inflammation of lupus nephritis (LN). Urine TWEAK (uTWEAK) levels were found to be associated with renal disease activity among patients with LN. Here, we determined whether serial measurements of uTWEAK during induction therapy could predict treatment response or not. METHODS: Spot urine samples were collected from patients with biopsy-proven active LN at time of flare, and 3 and 6 months after flare to assess the uTWEAK levels. All patients received standard immunosuppressive therapy and treatment response was evaluated at 6 months. The performance of uTWEAK as a predictor for treatment response was compared with clinically used biomarkers for patients with LN. RESULTS: Among 110 patients with LN, there were 29% complete responders (CR), 34% partial responders (PR) and 37% non-responders (NR). On average, uTWEAK level was consistently low in CR, trended down by 3 months in PR and persistently elevated in NR. uTWEAK levels at month 3 were able to predict complete response at month 6 (OR adjusted for age, sex and creatinine=0.34 [95% CI 0.15 to 0.80], the area under the receiver operating characteristic curve [ROC-AUC]=0.68, p=0.02). The optimal threshold for uTWEAK level at month 3 was 0.46 pg/mgCr, discriminating complete response with 70% sensitivity and 63% specificity. Combining uTWEAK and urine protein at month 3 improved predictive performance for complete response at 6 months (ROC-AUC 0.83, p<0.001). CONCLUSIONS: In addition to urine protein, uTWEAK level at 3 months after flare can improve the accuracy in predicting complete response at 6 months of induction therapy.
RESUMEN
OBJECTIVE: The optimal treatment of relapse or resistant lupus nephritis (LN) is still unclear. Mycophenolate might be an alternative therapy to avoid toxicities of cyclophosphamide (CYC). This study was aimed to compare enteric-coated mycophenolate sodium (EC-MPS) versus intravenous CYC as an induction therapy. METHODS: The study was a 12-month period of multicentre, open-labelled randomised controlled trial. Fifty-nine patients who had relapsed (36%) or who were resistant to previous CYC treatment (64%) and all who were biopsy-proven class III/IV, were randomised into CYC (n=32) and EC-MPS groups (n=27). The CYC group received intravenous CYC 0.5-1â g/m(2) monthly and the EC-MPS group was treated with EC-MPS 1440â mg/day for first 6â months. After induction therapy, both groups received EC-MPS 720â mg/day until the end of study at 12â months. RESULTS: The study was prematurely terminated due to high rate of serious adverse events in CYC arm. Death and serious infections were observed more in the CYC group (15.6% in CYC and 3.5% in EC-MPS; p=0.04). The early discontinuation rates, mainly from serious infections, were significantly higher in CYC group (percentage differences of 16.9; 95% CI 1.3 to 32.4). At the 12th month, both arms were comparable in terms of complete and partial remission rates (68% CYC and 71% EC-MPS) and times to remission (96â days CYC and 97â days EC-MPS). Composites of unfavourable outcomes (death, doubling of serum creatinine, non-remission and intolerance to treatment) were 46.9% and 37% in CYC and EC-MPS (risk difference=9.84; p=0.44). CONCLUSIONS: EC-MPS may have comparable efficacy, but was better tolerated than CYC. EC-MPS should be an alternative choice of treatment for difficult-to-treat LN, particularly in CYC-experienced LN patients. Due to an early termination of the study, further clinical implementation could be cautiously used. TRIAL REGISTRATION NUMBER: Clinicaltrials.gov ID#NCT01015456.
