Patients with severe acute kidney injury who require renal replacement therapy have high mortality rates. Controversy exists over whether a mortality benefit occurs with use of a more intensive renal replacement therapy regimen. In this multicenter, prospective study, 1124 patients requiring renal replacement therapy for severe acute kidney injury were randomized to a more and a less intensive renal replacement therapy regimen and were followed for 60 days. There was no statistical difference in mortality at 60 days (53.6% intensive, 51.5% less intensive, P = 0.47) and no difference in kidney recovery or non-renal organ failure. Hypotension and electrolyte abnormalities were more common in the intensive renal replacement regimen. A less intensive renal replacement regimen (intermittent hemodialysis 3 times a week or continuous venovenous hemodiafiltration at 20ml/kg/hour) was found noninferior to a more intensive renal replacement strategy (dialysis 6 times per week or continuous venovenous hemodiafiltration at 35 ml/kg/hour).

Renal replacement therapy (RRT) can be used to support patient’s kidney function in cases of acute kidney injury (AKI). However, timing, modality, and dosing of RRT continue to remain in question. Recent studies have begun to provide data to help guide clinicians on when to initiate RRT, what form of RRT to use ranging from continuous venovenous hemofiltration (VVH) to intermittent hemodialysis, and the impact of high versus low-intensity dosing. Additionally, the risks associated with temporary vascular access with regard to thrombosis and infection, the impact of high efficiency and flux versus low efficiency and flux membranes, and options for anticoagulation in RRT for AKI are also discussed. This review contains 75 references.  Key words: acute kidney injury, chronic kidney disease, continuous venovenous hemofiltration, continuous venovenous hemodialysis, renal replacement therapy, venovenous hemofiltration,

INTRODUCTION: Acute kidney injury (AKI) is the sudden loss of renal function with accumulation of nitrogenous waste compounds. In developing countries, community acquired AKI is common than AKI in hospitalized septic patients. With conservative management many patients recover renal function however few require renal support with intermittent Hemodialysis (HD). We conducted a study to find out the etiology and outcome of the patients presenting with AKI who required dialysis.METHODS: This is a descriptive follow up study of the patients who needed renal replacement therapy in the form of HD presenting to our Nephrology unit of the hospital over a period of two years. Patients were followed up for three months post discharge. Data were tabulated and analyzed using SPSS software.RESULTS: Total 50 patients were included in study with 67% male. The commonest etiologies were urinary tract infection (30%) and  acute gastroenteritis (24%).The mean creatinine at the time of nephrology consultation, maximum level and at the time of discharge were 6.5(SD± 2.62), 7.3(SD ±2.13) and 2.2(SD ±1.75) respectively. Uremia with anuria was the most common reason for the initiation of HD in 54% cases. The mean number of intermittent HD used was 3.36. Complete recovery was seen in 68%, death in 26% and CKD in 6%.CONCLUSION: UTI followed by acute gastroenteritis are the leading cause of AKI in our tertiary level hospital. Timely initiated renal replacement therapy in the form of intermittent HD could lead to substantial renal recovery in almost three fourth of patients.

Purpose: This case report describes a patient with dabigatran accumulation due to acute kidney injury on chronic kidney disease, requiring multiple administration of idarucizumab along with renal replacement therapy because of rebound effect causing numerous episodes of bleeding. Summary: An 86-year-old man on dabigatran etexilate 110 mg twice daily for stroke prevention with atrial fibrillation was admitted to the hospital for bowel obstruction and severe acute kidney injury on chronic kidney disease. The patient had an abnormal coagulation profile and no history of bleeding. Initial laboratory values revealed a hemoglobin concentration of 10.7 g/dL, a platelet count of 115 × 103 platelets/μL, an activated partial thromboplastin time of 150.4 seconds, an international normalized ratio of 10.28, a thrombin time greater than 100 seconds and a serum creatinine of 5.54 mg/dL (490 μmol/L). An initial dose of idarucizumab was administered 1 hour prior to surgery to prevent bleeding. Significant bleeding and hemodynamic instability occurred following surgery. Three additional doses of idarucizumab, 2 sessions of intermittent hemodialysis, continuous venovenous hemofiltration and blood products were required to achieve normalization of coagulation parameters and hemodynamic stability due to rebound coagulopathy after each dose of idarucizumab. Conclusion: Acute kidney injury on chronic kidney disease and third-space redistribution could have led to important dabigatran accumulation and favored rebound coagulopathy. Multiple therapeutic approaches may be required in the management of complex dabigatran intoxication.

Introduction. Acute kidney injury (AKI) is a common occurrence in the intensive care unit (ICU). Studies have looked at outcomes of renal replacement therapy using intermittent haemodialysis (IHD) in ICUs with varying results. Little is known about the outcomes of using IHD in resource-limited settings where continuous renal replacement therapy (CRRT) is limited. We sought to determine outcomes of IHD among critically ill patients admitted to a low-income country ICU.Methods. A retrospective review of patient records was conducted. Patients admitted to the ICU who underwent IHD for AKI were included in the study. Patients’ demographic and clinical characteristics, cause of AKI, laboratory parameters, haemodialysis characteristics, and survival were interpreted and analyzed. Primary outcome was mortality.Results. Of 62 patients, 40 had complete records. Median age of patients was 38.5 years. Etiologic diagnoses associated with AKI included sepsis, malaria, and ARDS. Mortality was 52.5%. APACHE II (OR 4.550; 95% CI 1.2–17.5,p=0.028), mechanical ventilation (OR 13.063; 95% CI 2.3–72,p=0.003), and need for vasopressors (OR 16.8; 95% CI 3.4–82.6,p=0.001) had statistically significant association with mortality.Conclusion. IHD may be a feasible alternative for RRT in critically ill haemodynamically stable patients in low resource settings where CRRT may not be available.

Background: Sustained low efficiency dialysis (SLED) has been evolved in recent years as technical hybrid of continuous renal replacement therapy and intermittent hemodialysis. It offers optimized hemodynamic stability of the critically ill patients with acute kidney injury (AKI). Our aim was to evaluate the hemodynamic tolerability of SLED in hemodynamically unstable patients with AKI.Methods: This prospective experimental study was conducted in Intensive Care Unit of BIRDEM General Hospital, Dhaka over a period of one year.Results: Forty three hemodynamically unstable patients with AKI were treated with one fifty three sessions of SLED. Mean arterial pressure of the patients before starting dialysis were 80.58±10.92 mmHg and 69.8% patients were on inotrope support. There were no significant differences (p>0.05) in mean arterial pressure during the procedure. No significant changes (p>0.05) occurred in pulse, respiratory rate and temperature during the sessions. Only thirty six out of 153 SLED sessions were associated with complications and hypotension was the commonest one (20.26%). Hypotensive episodes were effectively managed with addition or dose escalation of inotropes. No dialysis had to be discontinued because of hypotension/arrhythmia.Conclusion: SLED is an effective renal replacement therapy for the critically ill patients with AKI which maintains their hemodynamic stability.Birdem Med J 2016; 6(2): 84-90

Abstract Background : Currently, there is limited epidemiology data on acute kidney injury (AKI) in Indonesia.Therefore, we assessed the incidence of AKI and the utilization of renal replacement therapy (RRT) in Indonesia. Methods : Demographic and clinical data were collected from 952 ICU participants. The participants were categorized into AKI and non-AKI groups. The participants were further classified according to the 3 different stages of AKI as per the Kidney Disease Improving Global Outcome (KDIGO) criteria. Results : Overall incidenceof AKI was 43%. The participants were divided into three groups based on the AKI stages: 18.5% had stage 1, 33% had stage 2, and 48.5% had stage 3. Primary diagnosis of renal disease and high APACHE II score were the risk factors associated with AKI (OR = 4.53, 95% CI: 1.67-12.33, p=0.003 and OR = 1.14 per 1 unit increase, 95% CI: 1.09-1.20, p<0.001, respectively).Chronic kidney disease was the risk factor for severe AKI. Sepsis was the leading cause of AKI.Among the AKI participants, 24.6% required RRT. The most common RRT modalities were intermittent hemodialysis (71.7%), followed by slow low-efficiency dialysis (22.8%), continuous renal replacement therapy (4.3%), and peritoneal dialysis (1.1%). Conclusions : This study showed that AKI was a common problem in the Indonesian ICU. We strongly believe that identification of the risk factors associated with AKI will help us develop a predictive score for AKI so we can prevent and improve AKI outcome in the future.

Abstract Background : Currently, there is limited epidemiology data on acute kidney injury (AKI) from Southeast Asia, especially from Indonesia which is one of the biggest countries in Southeast Asia. Therefore, we assessed the prevalence of AKI and the utilization of renal replacement therapy (RRT) in Indonesia. Methods : Demographic and clinical data were collected from 952 ICU participants. The participants were categorized into AKI and non-AKI groups. The participants were further classified according to the 3 different stages of AKI as per the Kidney Disease Improving Global Outcome (KDIGO) criteria. We then assessed the Acute Physiology and Chronic Health Evaluation (APACHE) II score of AKI and non-AKI participants. RRT modalities were listed according to the number of times the procedures were carried out. Results : Overall incidence of AKI was 43%. The participants were divided into three groups based on the AKI stages: 18.5 % had stage 1, 33% had stage 2, and 48.5 % had stage 3. The use of mechanical ventilation was higher among the participants with AKI compared to the non-AKI participants. Also, AKI participants had higher average APACHE score compared to the non-AKI participants (16.5 vs 9.9). Among the AKI participants, 24.6% required RRT. The most common RRT modalities were intermittent hemodialysis (69.4%), followed by slow low-efficiency dialysis (22.1%), continuous renal replacement therapy (4.2%), and peritoneal dialysis (1.1%). Conclusions : This study showed that AKI is a common problem in the Indonesian ICU and had a high mortality rate. We strongly believe that identification of the risk factors associated with AKI will help us to develop a predictability score for AKI so we can prevent and improve AKI outcome in the future.
