Diabetes insipidus como manifestação inicial de leucemia mieloide aguda em paciente com monossomia do cromossomo 7 / Diabetes insipidus as initial manifestation of acute myeloid leukemia in a patient with monosomy of chromosome 7

O diabetes insipidus (DI) central é uma síndrome caracterizada pela incapacidade de concentração urinária devido à deficiência do hormônio antidiurético. O envolvimento do sistema nervoso central é frequente nas leucemias, mas a ocorrência de DI é rara e confere pior prognóstico. A patogênese do DI na leucemia não é totalmente conhecida, mas a infiltração do eixo hipotálamo-hipofisário por células leucêmicas parece ser um fator responsável. O presente relato descreve o caso de um paciente que apresentou DI como primeira manifestação de leucemia mieloide aguda e que evoluiu com dificuldades de ajustes do sódio sérico, da poliúria e da reposição volêmica, necessitando de permanência prolongada em unidade de cuidados intensivos(AU)

Central diabetes insipidus (DI) is a syndrome characterized by the inability to concentrate urine due to a lack of antidiuretic hormone. Involvement of the central nervous system is common in acute leukemia, but the occurrence of DI is rare and determines a worse prognosis. The pathogenesis of DI in leukemia has not been fully understood yet, but infiltration of the hypothalamic-pituitary axis by leukemic cells seems to be involved. This report describes a case of a patient who presented with DI as the first manifestation of acute myeloid leukemia. Difficulties in the management of serum sodium, fluid replacement and polyuria led to prolonged length of stay in an intensive care unit(AU)

Successful Peritoneal Dialysis in an Extremely Preterm Infant

Peritoneal dialysis can be considered renal supportive therapy, even in an extremely low birth weight infant with acute kidney injury not responding to general supportive measures. Although there have been several reports of successful peritoneal dialysis in extremely low birth weight infants, general practice guidelines and commercially available optimal peritoneal dialysis catheters have not been introduced. We report a successful case of peritoneal dialysis in an extremely low birth weight infant born at 25 weeks gestational age, with birth weight 790 g, with uncontrollable metabolic acidosis, hyperkalemia, progressive azotemia and continued anuria.

Duration of anuria predicts recovery of renal function after acute kidney injury requiring continuous renal replacement therapy

BACKGROUND/AIMS: Little is known regarding the incidence rate of and factors associated with developing chronic kidney disease after continuous renal replacement therapy (CRRT) in acute kidney injury (AKI) patients. We investigated renal outcomes and the factors associated with incomplete renal recovery in AKI patients who received CRRT. METHODS: Between January 2011 and November 2013, 408 patients received CRRT in our intensive care unit. Of them, patients who had normal renal function before AKI and were discharged without maintenance renal replacement therapy (RRT) were included in this study. We examined the incidence of incomplete renal recovery with an estimated glomerular filtration rate < 60 mL/min/1.73 m² and factors that increased the risk of incomplete renal recovery after AKI. RESULTS: In total, 56 AKI patients were discharged without further RRT and were followed for a mean of 8 months. Incomplete recovery of renal function was observed in 20 of the patients (35.7%). Multivariate analysis revealed old age and long duration of anuria as independent risk factors for incomplete renal recovery (odds ratio [OR], 1.231; 95% confidence interval [CI], 1.041 to 1.457; p = 0.015 and OR, 1.064; 95% CI, 1.001 to 1.131; p = 0.047, respectively). In a receiver operating characteristic curve analysis, a cut-off anuria duration of 24 hours could predict incomplete renal recovery after AKI with a sensitivity of 85.0% and a specificity of 66.7%. CONCLUSIONS: The renal outcome of severe AKI requiring CRRT was poor even in patients without further RRT. Long-term monitoring of renal function is needed, especially in severe AKI patients who are old and have a long duration of anuria.

Kidney Transplantation from the Deceased Donor Who Need Continuous Renal Replace Therapy / 대한이식학회지

BACKGROUND: Brain death donors may require continuous renal replacement therapy (CRRT) in severe acute renal failure (ARF) during management. To maximize donor organ usage we performed renal transplantation from deceased donors requiring CTTR with informed consent. This single-center study reviewed the clinical outcomes of kidney transplant recipients from extreme marginal donors requiring CRRT. METHODS: Medical records of all patients using a graft from extreme marginal donors who underwent CRRT in Asan Medical Center between June 2007 and September 2014 were reviewed retrospectively. RESULTS: Between June 2007 and September 2014, 27 kidneys were transplanted from 19 CRRT donors. Mean donor age was 35.1 years (range; 16~56), male donors were 14 (74%). The causes of brain death included head trauma in 6, hypoxia in 5, stroke in 4, and others in 4. The main causes of CRRT were anuria in 14, electrolyte imbalance or acidosis in 5, and mean duration of donor CRRT was 3.6 days (range; 1~11). Delayed graft function (DGF) developed in 24 (88.9%), but all recovered renal function; they can be free from dialysis 11 days after transplantation. Mean serum creatinine level at 1 month, 1 year, and 5 years was 1.85, 1.26, and 1.31 mg/dL, respectively. CONCLUSIONS: Five-year follow-up data showed that renal transplantation from severe ARF donor has an excellent outcome. Although CRRT donor kidney transplants have a higher rate of DGF, the presence of DGF, unlike other donation after brain death donor kidney transplants, does not portend a worse prognosis.

Etiology and outcomes of anuria in acute kidney injury: a single center study

BACKGROUND: It was previously known that anuric acute kidney injury (AKI) is uncommon and its occurrence suggests complete ureteral obstruction, shock, or a major vascular event. As the epidemiology of AKI has significantly changed over the past decade, it is possible that the incidence, etiology, or clinical characteristics of anuric AKI have also changed. METHODS: A prospective cohort study was conducted that included all patients undergoing renal replacement therapy (RRT) for AKI during a 2-year period in a tertiary hospital. Patients were classified as having anuric, oliguric, or nonoliguric AKI based on their volume of urine when RRT started using the modified Acute Kidney Injury Network criteria. RESULTS: Of the 203 patients included in the study, 21.2% met the criteria for anuric AKI. Septic and postoperative AKI were the main causes of anuric AKI, with 60.5% of incidences occurring in hospital. Anuric AKI was associated with a younger age, a lower prevalence of pre-morbid chronic kidney disease and diabetes, more frequent continuous RRT requirement, and multi-organ dysfunction. In addition, patients with anuric AKI had a higher rate of in-hospital mortality and long-term dependence on RRT than patients with nonanuric AKI. CONCLUSION: Anuric AKI is common, with sepsis as the main etiological insult, and is associated with adverse outcomes among patients with AKI who require RRT.

Blue Toe Syndrome after Percutaneous Coronary Intervention / 대한피부과학회지

Blue toe syndrome involves blue or purplish toes in the absence of trauma, serious cold exposure, or disorders causing general cyanosis. Clinical presentation can range from a cyanotic toe to a diffuse, multi-organ systemic disease. A 75-year-old man presented with claudication, sudden bilateral painful discoloration of the sole, blue-colored toes, and anuria. Three weeks earlier, he had been diagnosed with acute myocardial infarction and had undergone catheterization for percutaneous coronary intervention. Histopathologic findings showed vascular ectasia with mild perivascular inflammation. Based on patient history, physical examination, and laboratory findings, he was diagnosed with blue toe syndrome. Our patient presented with clinical manifestations, including peripheral cutaneous involvement and acute deterioration of renal function. This case highlights the importance of prompt diagnosis of blue toe syndrome by careful history-taking and physical examination in order to avoid multi-organ systemic disease.

Síndrome da angústia respiratória aguda associada à varicela em paciente adulto: exemplo de suporte respiratório extracorpóreo em doenças endêmicas brasileiras / Varicella associated acute respiratory distress syndrome in an adult patient: an example for extracorporeal respiratory support in Brazilian endemic diseases

Descreveu-se aqui o caso de um homem de 30 anos de idade com quadro de varicela grave, hipoxemia refratária, vasculite do sistema nervoso central e insuficiência renal anúrica. Foi necessário transporte por ambulância com suporte respiratório extracorpóreo veno-venoso, sendo este utilizado até a recuperação do paciente. Discute-se o potencial uso de oxigenação por membrana extracorpórea em países em desenvolvimento para o controle de doenças comuns nestas áreas.

A case of a 30 year-old man presenting with severe systemic chickenpox with refractory hypoxemia, central nervous system vasculitis and anuric renal failure is described. Ambulance transportation and support using veno-venous extracorporeal membrane oxygenation were necessary until the patient recovered. Ultimately, the potential use of extracorporeal membrane oxygenation support in low-middle income countries to manage common diseases is discussed.

Recovery of Delayed Graft Function after Calcineurin Inhibitor Sparing Regimen in a Renal Transplant Patient with Calcineurin Inhibitor Toxicity: A Case Report / 대한이식학회지

The recipient candidate was a 51-year-old male with end-stage renal disease owing to diabetes mellitus. The initial immunosuppressive regimen included basiliximab for induction and tacrolimus, mycophenolate mofetil, and steroids. Urine output was 413 mL/day on the operative day and 100 mL/day on the postoperative day (POD) 1. There was no definite stenosis of the ureter or vessels. He had anuria on POD 2~4 and he had undergone hemodialysis. His serum creatinine level did not decrease. Therefore, a graft biopsy was performed on POD 4. The pathologic finding was consistent with acute calcineurin inhibitor (CNI) toxicity. There was no evidence of rejection or acute tubular necrosis. Anuria continued on POD 6; therefore, we started sirolimus instead of a CNI based regimen. Graft function was gradually recovered 1 day after reduction of CNI dose and hemodialysis was stopped. The serum creatinine level was normalized on POD 10. He was discharged on POD 21.

Acute Kidney Injury and Postobstructive Diuresis Caused by a 4 mm Urinary Calculus

Urinary obstructions from ureteral calculi are one of the causes of postrenal acute kidney injury (AKI). Here we present a case of AKI caused by a 4 mm ureteral calculus with postobstructive diuresis following the spontaneous passage of the calculus. A 13-year-old girl who underwent nephrectomy for the removal of a neuroblastoma eight years previously, visited our institution because anuria had developed over the preceding five days. The serum creatinine level was elevated at 13.4 mg/dL. Radiological examinations showed the right solitary kidney with moderate hydronephrosis and a 4 mm calculus in the upper right ureter. The patient immediately underwent hemodialysis. After the ureteral calculus was passed spontaneously on day 2 of hospitalization, urinary output increased to more than 5,200 mL per day. Intravenous fluid replacement with careful monitoring of weight, intake, output, and serum and urine electrolytes was performed. On day 5 of hospitalization, the patient's condition stabilized.

Urolitíase em 76 cães / Urolithiasis in 76 dogs

Entre janeiro de 1990 e dezembro de 2010 foram necropsiados 4.872 cães no Laboratório de Patologia Veterinária da Universidade Federal de Santa Maria (LPV-UFSM). Destes, 76 (1,6%) apresentaram urólitos em algum local do sistema urinário. O perfil epidemiológico dos cães afetados demonstrou o predomínio de machos (64,5%), adultos (52,6%) e com raça definida (56,6%). Sinais clínicos indicativos de urolitíase foram reportados em 30,3% dos casos e consistiram principalmente de hematúria, anúria, disúria e incontinência urinária. Os urólitos tiveram localização única ou múltipla e os locais anatômicos mais frequentemente acometimentos, em ordem decrescente de frequência, foram: bexiga, rim e uretra. Urolitíase ureteral não foi observada. Lesões secundárias à urolitíase foram observadas em aproximadamente 40% dos cães afetados; as mais prevalentes, em ordem decrescente de frequência, foram: cistite, obstrução uretral, hidroureter, hidronefrose, ruptura vesical (com uroperitônio) e pielonefrite. Em 25% dos cães afetados ocorreu morte espontânea ou eutanásia decorrente das lesões secundárias à urolitíase. Lesões extra-renais de uremia foram observadas em 11,8% dos casos.

From January 1990 to December 2010, 4,872 dogs were necropsied at the Laboratório de Patologia Veterinária, Universidade Federal de Santa Maria. Seventy six dogs (1.6%) had uroliths along the urinary tract. The epidemiological profile of the affected dogs showed predominance of males (64.5%); adults (52.6%); and pure breeds (56.6%). Clinical signs suggestive of urolithiasis were reported in 30.3% of the dogs and consisted mainly of hematuria, anuria, dysuria and urinary incontinency. The uroliths were found in one or more anatomical sites, and the main affected ones (in descending order) were urinary bladder, kidney, and urethra. Ureteral urolithiasis was not observed. Secondary lesions to urolithiasis were found in about 40% of the cases. The most prevalent (in descending order) were cystitis, urethral obstruction, hydroureter, hydronephrosis, urinary bladder rupture (with uroperitoneum), and pyelonephritis. In 25% of the affected dogs, spontaneous death occurred or euthanasia was performed due to the secondary lesions of urolithiasis. Extra-renal lesions of uremia were found in 11.8% of the cases.

A Case of Acute Kidney Cortex Necrosis Caused by Tranexamic-Acid / 대한내과학회지

Kidney cortex necrosis is a relatively rare cause of acute kidney injury and is characterized by complete or partial destruction of the renal cortex, but sparing of the medulla. Tranexamic acid has antifibrinolytic activity and is used to reduce bleeding. We report a rare case of kidney cortex necrosis caused by tranexamic acid. A 49-year-old woman complained of coughing up blood-tinged sputum. She had a history of bronchiectasis and was treated with tranexamic acid for 3 days. Four days after admission, she developed anuria and azotemia. Computerized tomography showed enhancement of the renal medulla, but not the bilateral renal cortex. The patient was treated with hemodialysis, and has since been maintained on hemodialysis for 6 months. Due to the development of kidney cortex necrosis in patients treated with tranexamic acid, all its potential complications should be considered.

A Case of Severe Acute Kidney Injury by Near-Drowning

Acute kidney injury (AKI) secondary to near-drowning is rarely described and poorly understood. Only few cases of severe isolated AKI resulting from near-drowning exist in the literature. We report a case of near-drowning who developed to isolated AKI due to acute tubular necrosis (ATN) requiring dialysis. A 21-yr-old man who recovered from near-drowning in freshwater 3 days earlier was admitted to our hospital with anuria and elevated level of serum creatinine. He needed five sessions of hemodialysis and then renal function recovered spontaneously. Renal biopsy confirmed ATN. We review the existing literature on near-drowning-induced AKI and discuss the possible pathogenesis.

A Case of Multi-organ Failure due to Acute Chromic Acid Poisoning

Chromic acid is a strong metal acid and acute poisoning is very rare. However, chromic acid causes serious complications, such as skin injuries, as well as renal and hepatic failure. We report on a case of a 47-year-old male who accidentally had chromic acid spilled over his nose and face. For the first few days, he was treated with ascorbic acid and massive hydration. However, after three days, his condition began to worsen. He was treated with hemodialysis for anuria and acute renal failure, and antibiotics for pneumonia. On day 10 of hospitalization, he expired of multi-organ failure. We suggest firm control and close supervision of chromic acid in the work place, and, considering severe complications of chromic acid, we propose a nearly and aggressive treatment.

A Case of Neonate with Acute Renal Failure after Maternal Treatment with Angiotensin II Receptor Blocker / 대한주산의학회잡지

Hypertension is common medical problem encountered during pregnancy. However medication administered for maternal hypertension may cause fetal or neonatal complications. Angiotensin converting enzyme inhibitor or angiotensin II receptor blocker are rarely used during pregnancy, and there are few reports about the effect of them, because administration of these drugs during pregnancy may cause oligohydramnios, renal tubular dysplasia, hypocalvaria, pulmonary hypoplasia, intrauterine growth retardation, neonatal anuria and persistent ductus arteriosus. We report a case of neonatal acute renal failure by angiotensin II receptor blocker during pregnancy. In this case, the neonate with meconium aspiration was admitted to neonatal intensive care unit (NICU). During the NICU stay, neonatal anuria occurred, and there was a medical history that his mother took Candesartan Cilexeril (Atacand(R)), one of angiotensin II receptor blockers during pregnancy. The neonate showed intrinsic acute renal failure, so fluid was restricted and diuretics were administered to the neonate, and after 10 days, anuria improved.

Transurethral Rescetion Syndrome after Transurethral Resection of Bladder Tumor in 2 Patients on Maintenance Hemodialysis / 대한신장학회지

Transurethral resection syndrome (TURS) is one of the complications of endoscopic transurethral operation with irrigation fluid. TURS comprehensively refer to several clinical symptoms and signs caused by intravascular absorbtion of irrigation fluid, hypertension, bradycardia, arrhythmia, respiratory distress, hypotension, confusion, blindness, seizure, coma, hyponatremia, and hypoosmolarity. TURS is mainly known as the complication of the transurethral resection of prostate (TURP), and rarely found in the procedures such as transurethral resection of bladder tumor (TUR-BT), hysteroscopy, cystoscopy, and arthroscopy. Only a few cases of TURS after TUR-BT have been reported. The patients on maintenance hemodialysis were restricted in the amount of water intake for volume control. They were susceptible to the absorption of irrigation fluid during TUR-BT since they had anuria. We hereby report the 2 cases maintenance hemodialysis patients who were led to TURS after TUR-BT.

Anuria in a 9-Month-Old Infant Resulting from Ureteral Cystine Stones

Pediatric urolithiasis and calcular anuria in early infancy are rare. Cystine stones may develop in utero or during early infancy. We report the case of a female 9-month-old infant with obstructive anuria resulting from cystine stones in a single functioning unit. She presented to the emergency department owing to the absence of micturition for 3 days. Radiological investigations revealed four left ureteral stones and an atrophic right kidney resulting from a calcular obstruction. Her laboratory values were as follows: serum creatinine 6.7 mg/dl, Na 132 mEq/l, K 6 mg/dl, and hematocrit 32%. An urgent percutaneous nephrostomy tube was inserted into the left side for urinary drainage, and her serum levels of creatinine and K returned to normal within 3 days. A left ureterolithotomy was the final management. Stone analysis revealed pure cystine crystals.
