To investigate clinical course and outcome of dengue with acute respiratory failure (ARF), and to identify related risk factors for acquiring ARF in dengue, we retrospectively studied 11 dengue patients with ARF. From June to December 2002, a total of 606 adult patients were diagnosed as having dengue. Eleven (1.8%) of 606 dengue patients had complications of ARF. The main causes of ARF were sepsis (n = 6, 54.5%) and upper gastrointestinal (UGI) bleeding (n = 3, 27.3%). The mortality rate was 72.7% (n = 8). Additionally, univariate analysis showed that age, dyspnea, cough, prothrombin time, activated partial thromboplastin time, aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, creatinine, albumin, renal insufficiency, acute renal failure, acute hepatic failure, UGI bleeding, and combination bacterial infection were significantly predictive variables associated with dengue patients with ARF.

A 33-year-old woman without evidence of previous liver disease developed fulminant hepatic failure following the therapeutic dose of acetaminophen 3 days prior to admission. At admission, liver and renal function revealed hepatocellular injury with jaundice, and acute renal failure, total serum bilirubin 12.5 mg/ dL, direct serum bilirubin 8.1 mg/dL, aspartate aminotransferase 8460 IU/L, alanine aminotransferase 4640 IU/L, blood urea nitrogen 36 mg/dL, and serum creatinine 5.2 mg/dL. Two days later she developed multiorgan failure including hemodynamic disturbance with irreversible shock, and expired. Autopsy was performed, liver pathology showed severe centrilobular and midzonal necrosis, compatible with toxic hepatic necrosis, and renal pathology showed focal loss of tubular epithelial cells and partial occlusion of tubular lumen by cellular debris, compatible with acute tubular necrosis. Physicians should be aware of potential hepatotoxicity and nephrotoxicity of acetaminophen, even if given at therapeutic dosage in acute febrile illness.

Rhabdomyolysis induced acute renal failure (ARF) is relatively rare in children. We report an 8-year-old boy with McArdle disease and rhabdomyolysis induced ARF after heavy muscle work. Physical examination revealed generalized tenderness on his extremities. Laboratory examinations showed acute renal failure due to myoglobinuria and revealed alanine transaminase 428 U/l, aspartate transaminase 1,400 U/l, blood urea nitrogen 119 mg/dl, creatinin 3.6 mg/dl, uric acid 13 mg/dl, and serum creatinine kinase (CK) 33,766 U/l. Hemodialysis was carried out for ARF. His clinical and laboratory findings improved and became normal in 2 weeks. Enzymatic analysis of the muscle biopsy showed a phosphorylase A level of 129 nmol/s/mg protein (normal: 200-600) and a phosphorylase A+B level of 385 nmol/s/mg protein (normal: 500-1500), which was compatible with glycogenosis type V. As McArdle disease rarely becomes symptomatic and ARF secondary to this condition is very rare, our case represents a rare clinical presentation.

We report two cases of acute renal failure in patients with nonfulminant acute hepatitis A. First case is a healthy 25 year-old man complained of myalgia and jaundice. Initial laboratory results showed BUN 40 mg/dL, creatinine 5.23 mg/dL, AST 2,220 IU/L, ALT 3,530 IU/L, total bilirubin 6.26 mg/dL, and positive anti-HAV IgM antibody. Supportive treatments including fluid therapy were started. Serum creatinine and total bilirubin levels were 7.98 mg/dL and 7.66 mg/dL respectively on the 5th hospital day, and decreased gradually. He was discharged on the 12th hospital day, and was being followed up in outpatient department. Second case is a 33 year-old woman who admitted for bilateral flank pain, high fever, nausea, and vomiting. She was diagnosed as acute pyelonephritis and acute hepatitis A. On admission, BUN 13 mg/dL, creatinine 0.74 mg/dL, AST 3,720 IU/L, ALT 2,280 IU/L, total bilirubin 0.9 mg/dL were noted, and acute renal failure developed next day. Fluid therapy with antibiotics administration were started, and maximal BUN and creatinine was 41.7 and 8.09 mg/dL respectively on the 8th day. She recovered without dialysis and was discharged on the 19th hospital day. Proper and prompt comprehensive supportive measures would decrease the need for dialysis in patient of acute renal failue associated with acute hepatitis A.

Acute rhabdomyolysis is a syndrome characterized by the lesion of skeletal muscle resulting in subsequent release of intracellular contents into the circulatory system, which can cause potentially lethal complications. These contents include myoglobin, creatine phosphokinase, potassium, aldolase, lactate dehydrogenase and glutamic-oxaloacetic transaminase. There are numerous causes that can lead to acute rhabdomyolysis and many of patients present with multiple causes. The most common potentially lethal complication of rhabdomyoloysis is acute renal failure. In this article we present a case of a patient that developed clinical signs of acute rhabdomyolysis after consumption of heroin and alcohol. After approximately nine hours of alcohol and heroin induced coma he had acute compartment syndrome of the right arm, and clinical and laboratory signs of acute rhabdomyolysis with acute renal failure as a complication of rhabdomyolysis. Acute rhabdomyolysis developed in the patient as the result of acute compartment syndrome, with direct toxic activity of alcohol and diamorphine. During the period of coma, due to lying in particular position over a long period of time, pressure upon the certain part of the body caused muscle compression and capillary occlusion in fascial compartments, which led to ischemia. Upon pressure relief and beginning of tissue recovery, post ischemic compartment syndrome occurred with subsequent rhabdomyolysis. Getting out of coma the patient started to complain of severe pain in the right arm, which clinically worsened on passive stretching of the limb, with the loss of sensation and weakness. Laboratory findings showed high levels of creatine phosphokinase as the most sensitive marker of muscular damage. The peak of creatine phosphokinase level can be predictive for the development of acute renal failure because myoglobin level may return to normal within 6 hours after muscle injury. The peak of creatine phosphokinase (186.080 U/L; normal range 0-177) was recorded at 12 hours of admission. Other pertinent laboratory results such as urea, creatinine, prothrombin time, alanine aminotransferase and aspartate aminotransferase were also changed significantly. The peak of potassium level before dialysis was 6.8 mmol/L. Emergency fasciotomy of the anterior and posterior compartment syndrome was performed by a team of physicians after clinical examination. The second look debridement was performed at 48 and 72 hours. The plastic surgical procedure was performed 4 weeks later. On admission the patient also had oliguria with dark brown pigment in his urine. Arterial blood gases revealed metabolic and respiratory acidosis. The patient was hypovolemic and IV rehydratation with crystalloids, sodium bicarbonate and mannitol started immediately upon admission. Despite therapy his urine output decreased. Hemodialysis was initiated at serum potassium level of 6.8 mm/L and continued until his urine output returned to normal in three weeks. The patient was discharged from the hospital after six weeks, with normal urine output, without functional abnormality in his upper right limb. Acute rhabdomyolysis should be considered as a possibility in any patient with prolonged imobilization while in coma as well as in any intoxicated patient. Of course, creatine phosphokinase is the most sensitive indicator of muscle injury and the degree of creatine phosphokinase elevation correlates with the amount of muscle injury and disease severity. Other laboratory findings can help identify common complications of rhabdomyolysis such as acute renal failure, metabolic derangements and disseminated intravascular coagulopathy.

A 10-year-old boy with osteosarcoma and normal renal function manifested laboratory evidence of impending renal toxicity and extreme elevation of aspartate aminotrasferase and alanine aminotransferase within 2 hours after the completion of a 4-hour infusion of high-dose methotrexate (MTX) (12 g/m2), and went on to develop acute renal failure with life-threatening hyperkalemia 29 hours later. Although his renal function recovered completely with high-dose leucovorin, hemodialysis, charcoal hemoperfusion, and carboxypeptidase G2, we present this case to emphasize that signs of renal toxicity may be present as early as 2 hours after the completion of a 4-hour MTX infusion, and to suggest that monitoring for MTX toxicity should perhaps begin within a few hours after the completion of 4-hour MTX infusion.

Hepatitis C virus (HCV) infection is the most common blood-borne viral infection in haemodialysis. It causes significant morbidity and long-term mortality. Practice of universal precautions has been reported to be sufficient to prevent HCV seroconversion in dialysis units. However, the seroconversion rate remains very high in many dialysis units. A previous study from 1995 to 1998 at our own hospital without isolation showed that nosocomial transmission is the major cause of HCV seroconversion. The present study was therefore conducted with the aim to study the impact of isolation on HCV seroconversion. In this prospective cohort study, with non-probability consecutive sampling, patients with HCV infection were dialysed in an isolated room. In addition, standard universal precautions were practiced. HCV seroconversion rate was compared with the previous study. All patients with end-stage kidney disease (ESKD) admitted to our hospital for renal replacement therapy were included in the present study. At the time of admission, HCV screening was done. All anti-HCV-positive patients were dialysed in an isolated room. While on maintenance haemodialysis, all patients were monthly tested for anti-HCV, aspartate aminotransferase and alanine aminotransferase. Any patient who had HCV seroconversion was transferred to an isolated room for maintenance haemodialysis. Patients with HCV infection were managed by further testing for HCV-RNA and liver biopsy. Every patient who ultimately received renal transplantation at our hospital was also tested for HCV just prior to renal transplantation as well as 3 months after renal transplantation. HCV infection was diagnosed by detecting anti-HCV antibodies using an ELISA-based third-generation diagnostic test kit. Serum bilirubin, aspartate aminotransferase and alanine aminotransferase were assayed using standard laboratory techniques. From March 2003 to February 2006, 1,417 patients were admitted for haemodialysis in our unit. Of these 1,077 (76%) had ESKD. Mean age of patients was 42.47 +/- 16.2 (14-94) and 70.39% were males. Patients with ESKD had had more dialysis sessions (10.9 +/- 39.5 vs. 4.4 +/- 5.95, p = 0.009), more blood transfusions and more pre-existing HCV infections (4.72 vs. 1.5%, p = 0.009) than patients with acute renal failure. Of the ESKD patients, 65.7% were discharged, 9.47% died, 1.85% were shifted to chronic ambulatory peritoneal dialysis and 22.46% patients received renal transplantation. Of the patients who received renal transplantation, HCV seroconversion was detected in 2.75%. In the previous study without isolation practices, the HCV seroconversion rate in transplanted patients was 36.2%. The hazard of HCV seroconversion was 0.97 (95% CI 0.93-1.02, p = 0.2) for each additional dialysis and 1.09 (95% CI 0.88-1.36, p = 0.37) for each additional blood transfusion. The study concludes that isolation of HCV-infected patients during haemodialysis significantly decreases the HCV seroconversion rate.

In a retrospective study, acute renal failure (ARF) was found in 10 (3.3%) among 304 hospitalized adults with dengue hemorrhagic fever (DHF), and 6 (60%) of the 10 patients with ARF died, whereas all 294 patients without ARF (controls) survived (P < 0.001). Compared with the controls, DHF patients with ARF were found to be significantly older (P = 0.002) and male predominant (P < 0.001) and to have higher frequency of previous stroke (P = 0.005), chronic renal insufficiency (P = 0.046), dengue shock syndrome (DSS; P < 0.001), gastrointestinal bleeding (P < 0.001), and concurrent bacteremia (P = 0.009), lower hemoglobin (P = 0.003) and serum albumin levels (P = 0.003), and higher incidences of prolonged prothrombin time (P < 0.001), elevated aspartate aminotransferase (P < 0.001), and alanine aminotransferase levels (P < 0.001). Multivariate analysis showed DSS (odd ratio = 220.0; P < 0.001) was an independent risk factor for development of ARF in DHF patients. The high fatality rate in DHF patients complicated with ARF in our series underscore the importance of clinicians' alertness to this potentially fatal complication so that initiation of timely appropriate treatment is possible.

Acute renal failure is a recognized manifestation of paracetamol toxicity, but comparatively little data is available concerning its onset and duration. The present study sought to characterize the time course of rising serum creatinine concentrations in paracetamol nephrotoxicity. Renal failure was defined by serum creatinine concentration >or=150 micromol/L (1.69 mg/dL) or >or=50% increase from baseline. Serum creatinine concentrations and alanine aminotransferase activity were considered with respect to the interval after paracetamol ingestion. There were 2068 patients with paracetamol overdose between March 2005 and October 2007, and paracetamol nephrotoxicity occurred in 8 (0.4%). All had significant hepatotoxicity, and peak serum alanine aminotransferase activity occurred at 2.5 days (2.2 to 2.9 days) after ingestion. Peak serum creatinine concentrations did not occur until 5.5 days (4.4 to 5.9 days) after ingestion (p = .031 by Wilcoxon test). Serum creatinine concentrations slowly restored to normal, and renal replacement was not required. In this patient series, rising serum creatinine concentrations only became detectable after more than 48 hours after paracetamol ingestion. Therefore, renal failure might easily be missed if patients are discharged home before this. Further work is required to establish the prevalence of paracetamol-induced nephrotoxicity, and its clinical significance.

Acute hepatitis A (AHA) is one of the most common infectious diseases; it is usually a self-limiting disease affecting the liver. Although extrahepatic manifestations are not common, some cases have been reported associated with acute renal failure. We reviewed the clinical features of patients with AHA complicated by acute renal failure (ARF group) and compared them with patients with noncomplicated AHA (non-ARF group). The medical records of 208 consecutive patients with AHA who were diagnosed between January 2003 and October 2008 were reviewed. We identified 15 patients (7.2%) with ARF associated with AHA. There were no differences between the ARF and non-ARF group with regard to gender and age. The peak value of alanine aminotransferase (ALT) (median: 6060 IU/L vs 1792 IU/L, P < 0.001), prothrombin time (PT) (International normalized ratio, median 1.72 vs 1.10, P < 0.001), and total bilirubin level (median: 9.6 mg/dL vs 6.3 mg/dL, P = 0.04) were significantly higher in the ARF than in the non-ARF group. Twelve patients (80%) recovered completely with haemodialysis (seven patients, 46.7%) or only conservative management (five patients, 33.3%), while one patient underwent liver transplantation because of fulminant hepatic failure, and two patients died because of fulminant hepatic failure. There were no deaths among patients with noncomplicated AHA in the non-ARF group. Five patients underwent kidney biopsy; two patients were diagnosed with acute tubular necrosis, two patients with acute interstitial nephritis with IgA nephropathy and one patient with acute tubulointerstitial nephritis. All patients in the ARF group had microscopic haematuria and proteinuria (100%vs 31.1%, P < 0.001). Urine sodium levels were more than 10 mEq/L in 10 patients. The findings of high urinary sodium concentrations, microscopic haematuria and proteinuria did not support the diagnosis of hepatorenal syndrome (HRS). Patients with AHA with ARF had higher ALT levels, more prolonged PTs, and higher total bilirubin levels. The prognosis for these patients was poorer than for those without ARF. However, the patients with ARF and nonfulminant AHA had recovered with proper treatment and should not be confused with patients that have HRS.
