    Hepatitis A infection may result in acute hepatitis, and rarely, fulminant hepatitis may ensue. Extrahepatic manifestations of hepatitis A are uncommon. The authors present the case of a 77-year-old male who had development of acute renal failure and pericarditis during the clinical course of acute hepatitis A infection. He died as a result of septic shock on the fifth day of hospitalization. To the best of our knowledge, this is the first report of both these rare and serious complications appearing in the same patient.

    Full Text Available The clinicopathological findings of cerebral edema were investigated in patients with acute hepatic failure autopsied at Okayama University Hospital between 1970 and 1980 retrospectively. Nine (64% of 14 hepatic failure cases were found to have cerebral edema during a post-mortem examination of the brain. Clinical features of the patients with cerebral edema were not significantly different from those of the patients without cerebral edema. However, general convulsions were observed more frequently in patients later found to have cerebral edema. Moreover, the length of time from deep coma to death was much shorter in the brain edema cases with cerebral herniation than without herniation.

    Acute hepatitis C (HCV) infection has been identified as an important cause of fulminant hepatic failure (FHF), characterized by rapid deterioration of liver function from massive hepatic necrosis leading to encephalopathy and multi-organ failure. We admitted a female patient at Shalamar Hospital with jaundice, fever, encephalopathy and coagulopathy of short duration with no history of any comorbidity. Her hepatitis viral screen revealed positive anti HCV. Her viral loads were also high. A diagnosis of FHF due to acute HCV infection was made. Patient was treated conservatively and improved gradually. In summary, acute HCV can cause FHF and should be ruled out in patients with FHF of unknown cause in an endemic country for HCV like Pakistan.

  4. the Pathogenesis of acute on Chronic Hepatitis B liver Failure

    Acute-on-chronic liver failure is a characteristic clinical liver syndrome, which should be differentiated from acute liver failure, acute decompensated liver cirrhosis and chronic liver failure. The pathogenesis of ACLF is not fully understood yet. Viral factors and immune injury have been reported to be the two major pathogenesis. This paper reviewed the researches on the pathogenesis of acute on chronic hepatitis B liver failure in recent years, to provide theoretical basis for prompt and accurate diagnosis and treatment of this syndrome. This would beneift for the prognosis and raise the survival rate of patients.

    Paracetamol is the most commonly used analgesic after cleft palate repair. It has rarely caused acute hepatic failure at therapeutic or supratherapeutic doses. Only one case of therapeutic paracetamol toxicity after cleft palate repair had been reported previously. Here, we present a similar patient who developed acute liver failure and hepatic encephalopathy after an uncomplicated cleft palate surgery. Lack of large prospective trials in young children due to ethical concerns increases the value of the case reports of acetaminophen toxicity at therapeutic doses. The dosing recommendations of paracetamol may need to be reconsidered after cleft palate surgery.

    Renal transplantation is often associated with severe complications. Except for acute rejection, infections and toxicity of immunosuppressive treatment are the most frequent problems observed after transplantation. Infections with hepatic viruses (HBV, HDV, HCV, HGV) and cytomegalic virus (CMV) are the main infectious complications after renal transplantation. Cyclosporine toxicity is not unusual for a patient with renal transplantation and is even more frequent for patients with hepatic impairment due to viral infections. The subjects of this report are two renal transplant recipients with acute pancreatitis, severe hepatitis and acute renal failure on graft, receiving immunosuppressive therapy for maintaining renal graft function

    Xylitol is a five-carbon sugar alcohol produced from natural resources frequently used as a sugar substitute for humans. We report the development and successful treatment of acute hepatic failure and coagulopathy in a dog after xylitol ingestion. A 9-year-old 4.95 kg (10.9 lb) neutered male Chihuahua was evaluated at a veterinary clinic for vomiting after ingesting 224 g (45 g/kg, 20.5 g/lb) of granulated xylitol. Hypoglycemia developed within 1-2 h, elevated liver values, suggesting the development of acute hepatic failure, within 12 h and coagulopathy less than 24 h after ingestion. Treatment included maropitant, intravenous dextrose, phytonadione, metronidazole, and fresh frozen plasma. N-acetylcysteine (NAC) and S-adensoyl-L-methionine (SAMe) provided hepatic detoxification and support. The dog survived and liver values returned to normal within 1 month post ingestion. No adverse effects to hepatic function have been identified 2 years after acute xylitol toxicity. This paper is one of the few reports of successful management of a dog with hypoglycemia, hepatic failure, and coagulopathy caused by xylitol toxicity. To date, this is the highest published xylitol dose survived by a dog, as well as the only reported case that documents laboratory changes throughout the course of toxicity and includes normal hepatic indices for 7 months following xylitol toxicity. The rapidly expanding use of xylitol in a variety of products intended for human consumption has led to a rise in xylitol toxicity cases reported in dogs, and clinicians should be aware that more dogs may potentially be exposed and develop similar manifestations.

    The presence of hepatic encephalopathy (HE) within 4 weeks is part of the criteria for defining acute-on-chronic liver failure (ACLF). The pathophysiology of HE is complex, and hyperammonemia and cerebral hemodynamic dysfunction appear to be central in the pathogenesis of encephalopathy. Recent data also suggest that inflammatory mediators may have a significant role in modulating the cerebral effect of ammonia. Multiple prospective and retrospective studies have shown that hepatic encephalopathy in ACLF patients is associated with higher mortality, especially in those with grade III-IV encephalopathy, similar to that of acute liver failure (ALF). Although significant cerebral edema detected by CT in ACLF patients appeared to be less common, specialized MRI imaging was able to detect cerebral edema even in low grade HE. Ammonia-focused therapy constitutes the basis of current therapy, as in the treatment of ALF. Emerging treatment strategies focusing on modulating the gut-liver-circulation-brain axis are discussed.

    We present a patient with no medical history admitted for jaundice and dark coloured urine. Further investigations revealed hepatitis A related acute liver failure while the patient had no travel history, nor contact with infected individuals. After admission, the patient deteriorated fulfilling the King's College criteria for acute liver failure. Two days after admission, he underwent liver transplantation and recovered. Careful investigation identified imported semi-dried tomatoes as the source of the hepatitis A infection. This patient was part of a foodborne hepatitis A outbreak in the Netherlands in 2010 affecting 13 patients. Virus sequence analysis of our patient's virus showed a strain commonly found in Turkey. Hepatitis A related acute liver failure is rare, but is associated with a poor prognosis. In developed countries, the incidence of hepatitis A is low, but foodborne outbreaks are emerging. Further, we review the literature on recent foodborne hepatitis A outbreaks in developed countries, hepatitis A related acute liver failure, and hepatitis A vaccine.

    Guinea pigs were sensitized with trinitrophenylated liver macromolecular protein fraction (TNP-LP1) prepared by using sodium trinitrobenzenesulfonate of strong immunogenicity as the hapten and LP1 as the carrier protein. The administration of trinitrophenylated hepatocytes and lipopolysaccharide to these TNP-LP1-sensitized guinea pigs through the mesenteric vein 2 weeks later resulted in the induction of acute hepatic failure accompanied by massive hepatic cell necrosis in almost all of the guinea pigs. Using this experimental model, the effect of Gomisin A on the induction of immunological acute hepatic failure was examined. As a result, the administration of gomisin A remarkably improved the survival rate and serum transaminase levels of the immunologically-induced acute hepatic failure guinea pigs. Gomisin A also improved the histological changes of the liver in these guinea pigs. These results suggested that gomisin A is effective for the improvement of immunologically-induced acute hepatic failure in our experimental model.

    Hepatitis E virus is a positive strand RNA virus with three open reading frames which is transmitted predominantly through the fecal contamination of water and food. It is the most common cause of acute liver failure in endemic areas. Pregnant women especially from the Indian subcontinent and Africa are at increased risk of contracting acute HEV infection as well as developing severe complications including ALF. Transmission of HEV occurs from mother to unborn child. Both maternal and fetal complications may occur, including abortion, fetal demise, preterm labor and maternal or neonatal death. The precise reasons for increased susceptibility to HEV infection during pregnancy and associated severe disease are still an enigma. Management is supportive and termination of pregnancy is not recommended as a general rule. Prevention of infection is of vital importance, as availability of clean drinking water can reduce the burden of this disease in the community. There is a need for future research to focus on prevention of ALF in pregnancy and to study the disease pathogenesis, which is not explicitly understood at present. The availability of a vaccine may alter the natural course of the disease in this select population which is at risk.

    2006-04-01

    Full Text Available Background: Conventional diagnostic procedures and therapy of acute liver failure (ALF and acute-on-chronic liver failure (ACLF focus on to identify triggering events of the acute deterioration of the liver function and to avoid them. Further objectives are to prevent the development respectively the progression of secondary organ dysfunctions or organ failure. Most of the times the endocrinological function of the liver can to a wide extent be compensated, but the removal of toxins can only marginally be substituted by conventional conservative therapy. To improve this component of the liver function is the main objective of extracorporal liver support systems. The following principles of liver support systems can be differentiated: Artificial systems, bioartifical systems and extracorporal liver perfusion systems. This HTA report focuses on artificial systems (e.g. BioLogic-DT/-DTPF, MARS, Prometheus, because only these approaches currently are relevant in the German health care system. In 2004 a category "Extracorporal liver assist device" was introduced in the list of "additional payments" in the German DRG-system, which makes reimbursement for hospitals using the technology in inpatient care possible, based on an hospital's individual contract with statutory sickness funds. Objectives: To report the present evidence and future research need on medical efficacy and economic effectiveness of extracorporal liver support devices for treatment of patients with ALF or ACLF based on published literature data. Are artificial liver support systems efficient and effective in the treatment of ALF or ACLF? Methods: An extensive, systematic literature search in medical, economic, and HTA literature data bases was performed. Relevant data were extracted and synthesised. Results: Relevant controlled trials were detected for BioLogic-DT and MARS. No randomised controlled trial on Prometheus was found. None of the included studies on BioLogic-DT showed

    AIM: To utilize transcatheter arterial steroid injection therapy (TASIT) via the hepatic artery to reduce hepatic macrophage activity in patients with severe acute hepatic failure.METHODS: Thirty-four patients with severe acute hepatic failure were admitted to our hospital between June 2002 to June 2006 providing for the possibility of liver transplantation (LT). Seventeen patients were treated using traditional liver supportive procedures, and the other 17 patients additionally underwent TASIT with 1000 mg methylprednisolone per day for 3 continuous days.RESULTS: Of the 17 patients who received TASIT, 13 were cured without any complications, 2 died, and 2 underwent LT. Of the 17 patients who did not receive TASIT, 4 were self-limiting, 7 died, and 6 underwent LT.Univariate logistic analysis revealed that ascites, serum albumin, prothrombin time, platelet count, and TASIT were significant variables for predicating the prognosis.Multivariate logistic regression analysis using stepwise variable selection showed that prothrombin time, platelet count, and TASIT were independent predictive factors.CONCLUSION: TASIT might effectively prevent the progression of severe acute hepatic failure to a fatal stage of fulminant liver failure.

    Acute-on-chronic liver failure (AoCLF) is the most common type of liver failure and is associated with high mortality. Fibrinogen is critical in maintaining primary and secondary hemostasis. Therefore, we prospectively analyzed the association between fibrinogen and outcomes in AoCLF patients. Plasma fibrinogen was measured in 169 AoCLF, 173 chronic hepatitis B (CHB), and 171 healthy patients using a coagulation method. The predictive ability of fibrinogen for 3-month mortality in AoCLF patie...

    The aim of this study was to investigate the effects of hepatic and renal failure on the pharmacokinetics of flunixin in carbon tetrachloride (CCl(4))- and glycerol-treated rats. After intravenous administration of flunixin (2 mg/kg), the plasma concentration of flunixin was measured by high-performance liquid chromatography. Both acute hepatic and renal failure resulted in significantly increased area under the curve (AUC), prolonged elimination half-life (t(1/2β)), and reduced total body clearance (Cl(tot)) compared with respective controls (Pflunixin.

    Differential gene expression profiles in Balb/cJ mouse model of acute hepatic failure in- fected with MHV-3 virus intervened by anti-hepatic failure compound (AHFC) and the changes of cytokines regulated by genes were investigated. The Balb/cj mice were divided into AHFC-intervened group and control group randomly. Acute hepatic failure model of Balb/cJ mice infected with MHV-3 virus was established. The survival rate in the two groups was observed. It was found that the survival rate in the AHFC-intervened group and control group was 90% and 50% re- spectively 48 h after intrapefitoneal injection of MHV-3 (P<0.05). Before and after the experiment, the cytokines in peripheral blood of the survival mice were determined, and RNA was extracted from survival mouse liver tissue for the analysis of the differential gene expression by a 36 kb mouse oli- gonuleotide DNA array. In all the genes of microarray there were 332 genes expressed differently in the two groups, in which 234 genes were up-regulated and 78 genes down-regulated. Through clustering analysis, the differential expression of immune related genes, including TNF receptor superfamily, Kctd9, Bcl-2, Fg12, IL-8, IL-6, IFN-γ, TNF-α etc. might be related with the curative effectiveness of AHFC. It was suggested that AHFC can balance the immune state of mouse model of acute hepatic failure infected with MHV-3 virus mainly through regulating the expression of immune related genes, decrease the immune damage and inhibit liver cell apoptosis of mouse acute hepatic failure model obviously so as to increase the survival rate of mouse models of acute hepatic failure.

    Full Text Available BACKGROUND Acute liver failure is a heterogeneous entity and its prognosis varies with the aetiology. In India and other developing countries, hepatitis A virus is an important cause of acute liver failure. The prognostic factors and outcome of such patients should be studied separately. AIM OF THE STUDY To study the outcome of patients with acute liver failure due to hepatitis A treated with intensive supportive care and to determine the prognostic factors predicting the transplant free survival. MATERIALS AND METHODS In this observational study, all patients admitted in our hospital with ALF due to hepatitis A virus infection during the period of 3 years from January 1st 2013 to December 31st 2015 were selected; 40 patients satisfied the inclusion and exclusion criteria. Detailed history taking, physical examination, haematological and biochemical investigations were performed. The day-to-day progress and treatment given until discharge or death were recorded. RESULTS Overall mortality in acute liver failure due to hepatitis A was 30%. Transplant free survival was 100% in patients with grade I and II encephalopathy, 66.6% in grade III encephalopathy and 22.2% in grade IV encephalopathy (P less than 0.001. Extrahepatic manifestations were observed in 29 patients (72.5%, the most common was thrombocytopenia in 22 patients (55% followed by acute kidney injury in 12 patients (30%. CONCLUSIONS The grade of hepatic encephalopathy was the single most important factor that determined the prognosis. Patients with grade I and II encephalopathy had 100% spontaneous survival rate.

    Hepatic encephalopathy in a hospitalized cirrhotic patient is associated with a high mortality rate and its presence adds further to the mortality of patients with acute-on-chronic liver failure (ACLF). The exact pathophysiological mechanisms of HE in this group of patients are unclear but hyperammonemia, systemic inflammation (including sepsis, bacterial translocation, and insulin resistance) and oxidative stress, modulated by glutaminase gene alteration, remain as key factors. Moreover, alcohol misuse, hyponatremia, renal insufficiency, and microbiota are actively explored. HE diagnosis requires exclusion of other causes of neurological, metabolic and psychiatric dysfunction. Hospitalization in the ICU should be considered in every patient with overt HE, but particularly if this is associated with ACLF. Precipitating factors should be identified and treated as required. Evidence-based specific management options are limited to bowel cleansing and non-absorbable antibiotics. Ammonia lowering drugs, such as glycerol phenylbutyrate and ornithine phenylacetate show promise but are still in clinical trials. Albumin dialysis may be useful in refractory cases. Antibiotics, prebiotics, and treatment of diabetes reduce systemic inflammation. Where possible and not contraindicated, large portal-systemic shunts may be embolized but liver transplantation is the most definitive step in the management of HE in this setting. HE in patients with ACLF appears to be clinically and pathophysiologically distinct from that of acute decompensation and requires further studies and characterization.

    While cardiopulmonary symptoms are common in patients undergoing classical or, due to physical exercise,exertional heat stroke, the failure of other organs is a rarely described phenomenon. Here we present two cases of acute hepatic failure, one due to classic heat shock, while the other occurred while the patient was doing a marathon-type running. Both cases presented with very high transaminases and significantly elevated international normalized ratio (INR). No other causes for liver failure could be identified but physical exhaustion and hyperthermia.

    A 58-year-old man was admitted to our hospital. Laboratory data showed severe liver injury and that the patient was positive for immunoglobulin M anti-hepatitis A virus (HAV) antibodies. He was also complicated with severe renal dysfunction and had an extremely high level of serum hepatocyte growth factor (HGF). Therefore, he was diagnosed with severe acute liver failure with acute renal failure (ARF) caused by HAV infection. Prognosis was expected to be poor because of complications by ARF and high serum HGF. However, liver and renal functions both improved rapidly without intensive treatment, and he was subsequently discharged from our hospital on the 21(st) hospital day. Although complication with ARF and high levels of serum HGF are both important factors predicting poor prognosis in acute liver failure patients, the present case achieved a favorable outcome. Endogenous HGF might play an important role as a regenerative effector in injured livers and kidneys.

    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 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.

    MicroRNA-122 (miR-122) is the foremost liver-related micro-RNA, but its role in the hepatocyte is not fully understood. To evaluate whether circulating levels of miR-122 are elevated in chronic-HCV for a reason other than hepatic injury, we compared serum level in patients with chronic hepatitis C to other forms of liver injury including patients with acute liver failure and healthy controls. MiR-122 was quantitated using sera from 35 acute liver failure patients (20 acetaminophen-induced, 15 other etiologies), 39 chronic-HCV patients and 12 controls. In parallel, human genomic DNA (hgDNA) levels were measured to reflect quantitatively the extent of hepatic necrosis. Additionally, six HIV-HCV co-infected patients, who achieved viral clearance after undergoing therapy with interferon and ribavirin, had serial sera miR-122 and hgDNA levels measured before and throughout treatment. Serum miR-122 levels were elevated approximately 100-fold in both acute liver failure and chronic-HCV sera as compared to controls (P < 0.001), whereas hgDNA levels were only elevated in acute liver failure patients as compared to both chronic-HCV and controls (P < 0.001). Subgroup analysis showed that chronic-HCV sera with normal aminotransferase levels showed elevated miR-122 despite low levels of hepatocyte necrosis. All successfully treated HCV patients showed a significant Log10 decrease in miR-122 levels ranging from 0.16 to 1.46, after sustained viral response. Chronic-HCV patients have very elevated serum miR-122 levels in the range of most patients with severe hepatic injury leading to acute liver failure. Eradication of HCV was associated with decreased miR-122 but not hgDNA. An additional mechanism besides hepatic injury may be active in chronic-HCV to explain the exaggerated circulating levels of miR-122 observed.

    Massive hepatic necrosis is a key event underlying acute liver failure, a serious clinical syndrome with high mortality. Massive hepatic necrosis in acute liver failure has unique pathophysiological characteristics including extremely rapid parenchymal cell death and removal. On the other hand, massive necrosis rapidly induces the activation of liver progenitor cells, the so-called "second pathway of liver regeneration." The final clinical outcome of acute liver failure depends on whether liver progenitor cell-mediated regeneration can efficiently restore parenchymal mass and function within a short time. This review summarizes the current knowledge regarding massive hepatic necrosis and liver progenitor cell-mediated regeneration in patients with acute liver failure, the two sides of one coin.

    We report on two Aboriginal patients with the hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome. Both presented with acute hepatic failure with severe hypertransaminasemia and coagulopathy, prompting evaluation for emergent liver transplantation. The diagnosis of HHH syndrome was based on the presence of typical metabolic abnormalities. A protein-restricted diet and L-arginine or L-citrulline supplementation were immediately started, with rapid normalization of liver function test results and other biochemical abnormalities. Molecular analysis of the SLC25A15 gene showed that the two patients were homozygous for the common French Canadian mutation (F188Delta). The diagnosis of HHH syndrome should be considered in patients with unexplained fulminant hepatic failure. There does not appear to be a genotype-phenotype correlation for this presentation, inasmuch as the only other reported patient presenting with this picture had two different point mutations. Early identification and prompt treatment of these patients is crucial to avoid liver transplantation and can be life saving.

    Nearly all rats develop massive hepatic cell necrosis and die upon intravenous administration of heat-killed Propionibacterium acnes followed by a small amount of Gram-negative lipopolysaccharide 7 days later. However, when such an experimental liver disorder is induced in rats raised for 4 or more weeks on food containing 0.06% of gomisin A extracted and purified from Schizandra chinensis, the survival rate rises, histological changes of the liver improve remarkably, and splenocyte reactivity to phytohemagglutinin and pokeweed mitogen as well as splenocyte interleukin 1 productivity are retained. These results suggested the possibility that the development of acute hepatic failure may be prevented with the oral administration of gomisin A.

    Hepatitis B (HBV) reactivation induced by chemotherapy is problem encountered recently in the management of malignant diseases. Chemotherapy-induced HBV reactivation may ultimately lead to terminal acute liver failure. Liver transplantation (LT) currently remains the only definitive treatment option for such cases, but is generally denied to patients suffering from malignancy. Here, the authors describe 2 cases of cancer-free and HBV graft re-infection-free survival after LT performed for terminal liver failure arising from HBV reactivation induced by chemotherapy for advanced stage lymphoma. These 2 cases, and some other reports in the literature, may suggest that patients suffering from hematologic malignancies and terminal liver disease can be considered for LT if the prognosis of their hematologic malignancy is good.

    2008-01-01

    The role of the high mobility group box 1 (HMGB-1) in acute hepatic failure and the ef- fect of artificial liver support system treatment on HMGB-1 level were investigated. Pig models of acute hepatic failure were induced by D-galactosamine and randomly divided into two groups with or without artificial liver support system treatment. Tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) levels were detected by the enzyme linked immunosorbent assay (ELISA), the expression of HMGB-1 by Western blot, and serum levels of HMGB-1, liver function and hepatic pathology were observed after artificial liver support system treatment. The levels of TNF-α and IL-1β were increased and reached the peak at 24th h in the acute hepatic failure group, then quickly decreased. The serum level of HMGB-1 was increased at 24th h in the acute hepatic failure group and reached the peak at 48th h, then kept a stable high level. Significant liver injury appeared at 24th h and was continuously getting worse in the pig models of acute hepatic failure. In contrast, the liver injury was significantly alleviated and serum level of HMGB-1 was significantly decreased in the group treated with artificial liver support system (P<0.05). It was suggested that HMGB-1 may participate in the inflammatory response and liver injury in the late stage of the acute liver failure. Artificial liver support system treatment can reduce serum HMGB-1 level and relieve liver pathological damage.

    The objective of this controlled experimental animal study was to evaluate whether acute hepatic failure (AHF) can cause acute lung injury (ALI) and to investigate possible pathophysiologic mechanisms. Seventeen domestic pigs were randomly assigned to AHF and sham groups. AHF was induced by surgical devascularization of liver in 10 animals. Seven animals were sham operated. Hemodynamics, lung mechanics, extravascular lung water (EVLW), and intracranial pressure, blood gas, liver function tests, and serum endotoxin levels were measured. Cells count, total protein, and phospholipids and phospholipases A(2) were determined in the bronchoalveolar lavage (BAL) fluid. Measurements were obtained after the insertion of central lines and 4 hours and 7 hours after the completion of the surgical procedure. Hemodynamic, biochemical, neuromonitoring, and histologic data confirmed the development of liver failure. Seven hours after devascularization, EVLW was higher in AHF (13.7 +/- 1.8 mL/kg) compared with the sham group (5.9 +/- 0.7 mL/kg) (P <.05); in AHF, increase of neutrophils (5% +/- 8% to 25% +/- 8%, P <.001), total protein (6.2 +/- 3.7 to 11.2 +/- 6.5 microg/mL, P <.048), and phospholipase A(2) (1.43 +/- 0.56 to 2.38 +/- 1.38 nmoL/mL/h, P <.03) and decrease in PAF-acetylhydrolase (0.114 +/- 0.128 to 0.039 +/- 0.038 nmol/mL/h, P <.01) compared with baseline were observed; total phospholipids decreased in AHF and increased in the sham model. Histologic examination confirmed lesions compatible with acute lung injury. In conclusion, AHF due to hepatic devascularization induced acute lung injury, confirmed by the increase of inflammatory cells in the alveoli as well as by histologic findings. The decreased PAF-AcH and the increased phospholipase A(2) may play a significant role in the perpetuation of inflammation accompanied by surfactant disorders.

    In acute hepatic failure auxiliary liver transplantation is an interesting alternative approach. The aim is to provide a temporary support until the failing native liver has regenerated.(1-3) The APOLT-method, the orthotopic implantation of auxiliary segments- averts most of the technical problems. However this method necessitates extensive resections of both the native liver and the graft.(4) In 1998, Erhard developed the heterotopic auxiliary liver transplantation (HALT) utilizing portal vein arterialization (PVA) (Figure 1). This technique showed promising initial clinical results.(5-6) We developed a HALT-technique with flow-regulated PVA in the rat to examine the influence of flow-regulated PVA on graft morphology and function (Figure 2). A liver graft reduced to 30 % of its original size, was heterotopically implanted in the right renal region of the recipient after explantation of the right kidney.  The infra-hepatic caval vein of the graft was anastomosed with the infrahepatic caval vein of the recipient. The arterialization of the donor's portal vein was carried out via the recipient's right renal artery with the stent technique. The blood-flow regulation of the arterialized portal vein was achieved with the use of a stent with an internal diameter of 0.3 mm. The celiac trunk of the graft was end-to-side anastomosed with the recipient's aorta and the bile duct was implanted into the duodenum. A subtotal resection of the native liver was performed to induce acute hepatic failure. (7) In this manner 112 transplantations were performed. The perioperative survival rate was 90% and the 6-week survival rate was 80%. Six weeks after operation, the native liver regenerated, showing an increase in weight from 2.3±0.8 g to 9.8±1 g. At this time, the graft's weight decreased from 3.3±0.8 g to 2.3±0.8 g. We were able to obtain promising long-term results in terms of graft morphology and function. HALT with flow-regulated PVA reliably bridges acute hepatic failure

    Acute hepatic failure (AHF) is a severe liver injury accompanied by hepatic encephalopathy which causes multiorgan failure with an extremely high mortality rate, even if intensive care is provided. Management of severe AHF continues to be one of the most challenging problems in clinical medicine. Liver transplantation has been shown to be the most effective therapy, but the procedure is limited by shortage of donor organs. Although a number of clinical trials testing different liver assist devices are under way, these systems alone have no significant effect on patient survival and are only regarded as a useful approach to bridge patients with AHF to liver transplantation. As a result, reproducible experimental animal models resembling the clinical conditions are still needed. The three main approaches used to create an animal model for AHF are: surgical procedures, toxic liver injury and infective procedures. Most common models are based on surgical techniques (total/partial hepatectomy, complete/transient devascularization) or the use of hepatotoxic drugs (acetaminophen, galactosamine, thioacetamide, and others), and very few satisfactory viral models are available. We have recently developed a viral model of AHF by meansof the inoculation of rabbits with the virus of rabbit hemorrhagic disease. This model displays biochemical and histological characteristics, and clinical features that resemble those in human AHF. In the present article an overview is given of the most widely used animal models of AHF, and their main advantages and disadvantages are reviewed.

    This is the first report from Norway of a patient with interstitial nephritis and renal failure due to non-fulminant hepatitis A virus (HAV) infection. HAV infection was confirmed by positive anti-HAV IgM serology. All tests for other virus infections were negative. At admittance serum creatinine (s-Creat) and blood urea nitrogen (BUN) concentration were 539 microlmol/l and 32.6 mmol/l increasing the following days to 890 micromol/l and 39.9 mmol/l, respectively. Nine courses of hemodialysis had to be given. Kidney biopsy specimen showed interstitial edema, lymphocytic cell infiltration and acute tubular injury with normal glomeruli. Examination with immunohistochemistry was negative. In contrast to the findings associated with HBV and HCV infection in which glomerular disease is predominantly found, the HAV infection in our patient was associated with interstitial nephritis and acute tubular necrosis. The prognosis of the renal failure due to HAV infection was good although the recovery was substantially delayed.

    Besides their role in the elucidation of pathogenic processes of medical and pharmacological nature, biomarkers can also be used to document specific toxicological events. Hepatic cells generated from human skin-derived precursors (hSKP-HPC) were previously shown to be a promising in vitro tool for the evaluation of drug-induced hepatotoxicity. In this study, their capacity to identify potential liver-specific biomarkers at the gene expression level was investigated with particular emphasis on acute liver failure (ALF). To this end, a set of potential ALF-specific biomarkers was established using clinically relevant liver samples obtained from patients suffering from hepatitis B-associated ALF. Subsequently, this data was compared to data obtained from primary human hepatocyte cultures and hSKP-HPC, both exposed to the ALF-inducing reference compound acetaminophen. It was found that both in vitro systems revealed a set of molecules that was previously identified in the ALF liver samples. Yet, only a limited number of molecules was common between both in vitro systems and the ALF liver samples. Each of the in vitro systems could be used independently to identify potential toxicity biomarkers related to ALF. It seems therefore more appropriate to combine primary human hepatocyte cultures with complementary in vitro models to efficiently screen out potential hepatotoxic compounds.

    Due to a combination of ingested ethanol and inhaled trichloroethylene (Tri) a 28 year old man developed toxic hepatitis and acute oliguric renal failure, both of which had a favorable evolution. Tri has been described as a cause of hepatic disfunction and acute renal failure due to acute tubular necrosis, although some of the cases described are controversial, because Tri was either contaminated by other dissolvents or could not be proven pure, with the exception of one case. In many there was ethanol ingestion. The Tri inhaled by our patient was found to contain less than 1% of carbon tetrachloride (C-Tchl). This would suggest the C-Tchl to be responsible for the clinical picture although the combination Tri/ethanol cannot be discarded as the causal agent, due to the small amount of contaminant present.

    Acute-on-chronic liver failure (AoCLF) is the most common type of liver failure and is associated with high mortality. Fibrinogen is critical in maintaining primary and secondary hemostasis. Therefore, we prospectively analyzed the association between fibrinogen and outcomes in AoCLF patients. Plasma fibrinogen was measured in 169 AoCLF, 173 chronic hepatitis B (CHB), and 171 healthy patients using a coagulation method. The predictive ability of fibrinogen for 3-month mortality in AoCLF patients was assessed using receiver operating characteristic (ROC) curve and multivariable logistic regression analyses. Plasma fibrinogen was significantly lower in nonsurvivor AoCLF patients compared with survivor AoCLF, CHB, and control patients. The sensitivity, specificity, and area under the ROC curve of 1/fibrinogen predicting mortality in AoCLF patients were 66.7%, 72.5%, and 0.746 (95% confidence interval (CI): 0.672-0.820, P fibrinogen cutoff value was 0.90 g/L. On multivariate logistic regression analysis, low fibrinogen was an independent factor predicting mortality (odds ratio: 0.304; 95% CI: 0.094-0.983; P = 0.047). Nonsurvivor AoCLF patients had significantly decreased fibrinogen levels, suggesting that low plasma fibrinogen may be a useful predictor of poor prognosis in AoCLF patients.

    AIM: To study the protective effect of eukaryotic expression plasmid encoding augmenter of liver regeneration (ALR) on acute hepatic injury and hepatic failure in rats. METHODS: The PCR-amplified ALR gene was recombined with pcDNA3 plasmid, and used to treat rats with acute hepatic injury. The rats with acute hepatic injury induced by intraperitoneal injection of 2 mL/kg 50% carbon tetrachloride (CCl4) were randomly divided into saline control group and recombinant pcDNA3-ALR plasmid treatment groups. Recombinant pcDNA3-ALR plasmid DNA (50 or 200 μg/kg) was injected into the rats with acute hepatic injury intravenously, intraperitoneally, or intravenously and intraperitoneally in combination 4 h after CCl4 administration, respectively. The recombinant plasmid was injected once per 12 h into all treatment groups four times, and the rats were decapitated 12 h after the last injection. Hepatic histopathological alterations were observed after HE staining, the expression of proliferating cell nuclear antigen (PCNA) in liver tissue was detected by immunohistochemical staining, and the level of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) was determined by biochemical method. The recombinant plasmid DNA (200 μg/kg) and saline were intraperitoneally injected into the rats with acute hepatic failure induced by intraperitoneal injection of 4 mL/kg 50% CCl4 after 4 h of CCl4 administration, respectively. Rats living over 96 h were considered as survivals.RESULTS: The sequence of ALR cDNA of recombinant pcDNA3-ALR plasmid was accordant with the reported sequence of rat ALR cDNA. After the rats with acute hepatic injury were treated with recombinant pcDNA3-ALR plasmid, the degree of liver histopathological injury markedly decreased. The pathologic liver tissues, in which hepatic degeneration and necrosis of a small amount of hepatocytes and a large amount of infiltrating inflammatory cells were observed, and they became basically normal in the

    Objective:To establish a kind of animal model of postoperative acute hepatic failure induced by hepatic ischemia & hepatectomy on rats with obstructive jaundice, which could show similar clinical pathophysiological changes in hunman beings. To investigate the influence of fasudil to this model.Method:Selected 96 Wistar big rats as animal model of obstructive jaundice, which were treated with ligation and cuting off common bile duct. Rats in low-dose group were immediately injected fasudil of 10 mg/kg through portal vein after hepatectomy, while rats in high-dose group were immediately injected fasudil of 30 mg/kg through portal vein after hepatectomy, rats in control group were immediately injected equivalent normal saline through portal vein after hepatectomy. To determine the serum ALT, AST, TBIL (tumor necrosis factor-α, TNF-α)and (interferon-γ, INF-γ) levels in postoperative rats with hepatic failure within 6 h; to determine the (superoxide dismutase, SOD) activity and (malondialdehyde, MDA) content in hepatic tissue; hepatic tissue HE staining to observe the pathological injury; to observe animal model 96 h of survival rate.Results:That Proceeding internal biliary drainage operation to rats after obstruction for 14 h, and blocking 70% of hepatic blood supply, excising remnant liver after 30 min was in accordance with criteria of hepatic failure animal, and was deserved to further research. Compared with control group, serum AST, ALT, TBIL, TNF-α, INF-γ levels decreased in fasudil treatment group, SOD activity increased in hepatic tissue, MDA content decreased, pathological injury in hepatic tissue reduced, rats 96 h of survival rate increased, and the effects of high-dose group were more obvious than that in low-dose group.Conclusion:A surgical hepatic failure model in rat was established, which showed similar clinical pathophysiological changes in hunman beings. In addition, we have found that fasudil possibly played a role of protection to hepatic

    BACKGROUND:Viral hepatitis B accounts for over 80%of acute hepatic failures in China and the patients die mainly of its complications. A patient with hepatic failure and fever is not uncommon, whereas repeated fever is rare. METHODS:A 32-year-old female was diagnosed with subacute hepatic failure and hepatitis B viral infection because of hyperbilirubinemia, coagulopathy, hepatic encephalopathy, serum anti-HBs-positive without hepatitis B vaccination, and typical intrahepatic pathological features of chronic hepatitis B. Plasma exchange was administered twice and she awoke with hyperbilirubinemia and discontinuous fever. RESULTS:Urethritis was conifrmed and medication-induced fever and/or spontaneous bacterial peritonitis (Gram-negative bacillus infection) was suspected. The patient was treated with antibiotics, steroids and a Chinese herbal medicine, matrine, for three months and she recovered. CONCLUSION:The survival rate of patients with hepatic failure might be improved with comprehensive supporting measures and appropriate, timely management of com-plications.

  10. Management of acute hepatitis B.

    Acute hepatitis B virus (HBV) is a common cause of acute icteric hepatitis in adults. The vast majority of these patients resolve this acute infection and develop long-lasting immunity. In contrast, the vast majority of patients who develop chronic HBV have minimal symptoms and do not develop jaundice after becoming infected with HBV. These patients will frequently remain undiagnosed for years or decades. Approximately 1% of persons with acute HBV develop acute liver failure. Preventing acute HBV with vaccination is the best treatment. Although universal vaccination is now administered to newborns in many countries, the majority of adults have not been vaccinated and remain at risk. Because the majority of patients with acute HBV resolve this infection spontaneously, treatment with an oral anti-HBV agent is not necessary. However, the use of an oral anti-HBV agent is not unreasonable to use in a patient who is developing acute liver failure from severe acute HBV.

    In the majority of children with ALF, the etiology is unknown and liver transplantation is often needed for survival. A patient case prompted us to consider that immune dysregulation may be the cause of indeterminate acute hepatitis and liver failure in children. Our study includes nine pediatric patients treated under a multidisciplinary clinical protocol to identify and treat immune-mediated acute liver injury. Patients with evidence of inflammation and no active infection on biopsy received treatment with intravenous immune globulin and methylprednisolone. Seven patients had at least one positive immune marker before or after treatment. All patients had a CD8+ T-cell predominant liver injury that completely or partially responded to immune therapy. Five of the nine patients recovered liver function and did not require liver transplantation. Three of these patients subsequently developed bone marrow failure and were treated with either immunosuppression or stem cell transplant. This series highlights the importance of this tissue-based approach to diagnosis and treatment that may improve transplant-free survival. Further research is necessary to better characterize the immune injury and to predict the subset of patients at risk for bone marrow failure who may benefit from earlier and stronger immunosuppressive therapy.

Their general conditions and survival were analyzed by survival analysis and Cox regression analysis.RESULTS: A total off 190 patients were included in this study. The overall 1-year survival rate was 57.6%. Patients not treated with antiviral drugs had a significantly higher mortality [relative risk (RR) = 0.609, P = 0.014].The highest risk off death in patients with ACLF was associated with hepatorenal syndrome (HRS) (RR = 2.084, P =0.026), while other significant factors were electrolyte disturbances (RR = 2.062, P = 0.010), and hepatic encephalopathy (HE) (RR = 1.879, P < 0.001).CONCLUSION: Antiviral therapy has a strong effffect on the prognosis off the patients with HBV-ACLF by improving their 1-year survival rate. HRS, electrolyte disturbances,and HE also affffect patient survival.

  15. Liver regeneration signature in hepatitis B virus (HBV-associated acute liver failure identified by gene expression profiling.

    Directory of Open Access Journals (Sweden)

    Oriel Nissim

    Full Text Available INTRODUCTION: The liver has inherent regenerative capacity via mitotic division of mature hepatocytes or, when the hepatic loss is massive or hepatocyte proliferation is impaired, through activation of hepatic stem/progenitor cells (HSPC. The dramatic clinical course of acute liver failure (ALF has posed major limitations to investigating the molecular mechanisms of liver regeneration and the role of HSPC in this setting. We investigated the molecular mechanisms of liver regeneration in 4 patients who underwent liver transplantation for hepatitis B virus (HBV-associated ALF. METHODS AND FINDINGS: Gene expression profiling of 17 liver specimens from the 4 ALF cases and individual specimens from 10 liver donors documented a distinct gene signature for ALF. However, unsupervised multidimensional scaling and hierarchical clustering identified two clusters of ALF that segregated according to histopathological severity massive hepatic necrosis (MHN; 2 patients and submassive hepatic necrosis (SHN; 2 patients. We found that ALF is characterized by a strong HSPC gene signature, along with ductular reaction, both of which are more prominent in MHN. Interestingly, no evidence of further lineage differentiation was seen in MHN, whereas in SHN we detected cells with hepatocyte-like morphology. Strikingly, ALF was associated with a strong tumorigenesis gene signature. MHN had the greatest upregulation of stem cell genes (EpCAM, CK19, CK7, whereas the most up-regulated genes in SHN were related to cellular growth and proliferation. The extent of liver necrosis correlated with an overriding fibrogenesis gene signature, reflecting the wound-healing process. CONCLUSION: Our data provide evidence for a distinct gene signature in HBV-associated ALF whose intensity is directly correlated with the histopathological severity. HSPC activation and fibrogenesis positively correlated with the extent of liver necrosis. Moreover, we detected a tumorigenesis gene signature

    Full Text Available Branched chain amino acid (BCAA transaminase activity increased in both the mitochondrial and supernatant fractions of brain from hepatic failure rats, in which a partial hepatectomy was performed 24h following carbon tetrachloride (CCl4 administration, although the activity of liver and skeletal muscle was the same as in control rats. The elevation of mitochondrial BCAA transaminase activity in liver-injured rats was partly due to increased activity of brain specific Type III isozyme. Branched chain alpha-ketoacid (BCKA dehydrogenase in the brain homogenates was not significantly altered in acute hepatic failure rats, while the liver enzyme activity was markedly diminished. BCKA dehydrogenase activity in the brain homogenates was inhibited by adding ATP to the assay system, and was activated in vitro by preincubating the brain homogenate at 37 degrees C for 15 min. These findings suggest that brain BCAA catabolism is accelerated in acute hepatic failure rats.

    Acute hepatic failure (AHF), which leads to an extremely high mortality rate, has become the focus of attention in clinic. In this study, Danhong injection (DHI) was investigated to evaluate the preventive and protective effect on AHF induced by lipopolysaccharide (LPS) and D-galactosamine (GalN) in mice. For AHF induction, ICR mice were intraperitoneally injected with D-GalN (700 mg/kg) and LPS (20  μ g/kg). DHI was administrated twice, at 12 and 1 h, respectively, before D-GalN/LPS injection. After stimulation with D-GalN/LPS for 1 and 6 h, serum and livers were collected for analysis. We found that mice administrated with DHI displayed a higher survival rate, lower serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), glutathione S-transferase (GST), and tumor necrosis factor (TNF)- α . DHI inhibited the elevations of hepatic lipid peroxidation (malondialdehyde), caspase-8 activity, and mRNA expression levels of inflammatory cytokines (interleukin-1 β and interleukin-6) increased by D-GalN/LPS in the liver. Furthermore, liver histopathological analysis indicated that the DHI group showed markedly fewer apoptotic (TUNEL positive) cells and less pathological changes than those in the AHF model group. These results provide a novel insight into the pharmacological actions of DHI as a potential candidate for treating AHF.

    Clinical infection by hepatitis A virus (HAV) is generally self-limited but in some cases can progress to liver failure. Here, an HAV outbreak investigation among children with acute liver failure in a highly endemic country is presented. In addition, a sensitive method for HAV whole genome amplification and sequencing suitable for analysis of clinical samples is described. In this setting, two fatal cases attributed to acute liver failure and two asymptomatic cases living in the same household were identified. In a second household, one HAV case was observed with jaundice which resolved spontaneously. Partial molecular characterization showed that both households were infected by HAV subtype IA; however, the infecting strains in the two households were different. The HAV outbreak strains recovered from all cases grouped together within cluster IA1, which contains closely related HAV strains from the United States commonly associated with international travelers. Full-genome HAV sequences obtained from the household with the acute liver failure cases were related (genetic distances ranging from 0.01% to 0.04%), indicating a common-source infection. Interestingly, the strain recovered from the asymptomatic household contact was nearly identical to the strain causing acute liver failure. The whole genome sequence from the case in the second household was distinctly different from the strains associated with acute liver failure. Thus, infection with almost identical HAV strains resulted in drastically different clinical outcomes.

    Emergency fibroscopy revealed bleeding lesions in 84 cirrhotic patients. In patients with moderate or no hepatic failure, the commonest actively bleeding sources were oesophagogastric varices and acute mucosal ulcers associated with the ingestion of anti-inflammatory drugs. In patients with severe hepatic failure, acute mucosal ulcers unrelated to drugs predominated and there was evidence that these were stress-induced erosions.

    The aim of this study was to investigate if a protective effect from hypothyroidism in acute liver failure resulted from reduced endoplasmic reticulum stress and changes to the redox environment. Twenty male Sprague-Dawley rats were divided in four groups: (1) euthyroid (sham surgery), (2) hypothyroid, (3) euthyroid (sham surgery)+thioacetamide and (4) hypothyroid+thioacetamide. Hypothyroidism was confirmed two weeks after thyroidectomy, and thioacetamide (TAA) (400mg/kg, ip) was administrated to the appropriate groups for three days with supportive therapy. Grades of encephalopathy in all animals were determined using behavioral tests. Animals were decapitated and their blood was obtained to assess liver function. The liver was dissected: the left lobe was used for histology and the right lobe was frozen for biochemical assays. Body weight, rectal temperature and T4 concentration were lower in hypothyroid groups. When measurements of oxidative stress markers, redox environment, γ-glutamylcysteine synthetase and glutathione-S-transferase were determined, we observed that hypothyroid animals with TAA compensated better with oxidative damage than euthyroid animals treated with TAA. Furthermore, we measured reduced expressions of GADD34, caspase-12 and GRP78 and subsequently less hypothyroidism-induced cellular damage in hypothyroid animals. We conclude that hypothyroidism protects against hepatic damage caused by TAA because it reduces endoplasmic reticulum stress and changes to the redox environment.

    Full Text Available BACKGROUND: High score of model for end-stage liver diseases (MELD before liver transplantation (LT indicates poor prognosis. Artificial liver support system (ALSS has been proved to effectively improve liver and kidney functions, and thus reduce the MELD score. We aim to evaluate whether downgrading MELD score could improve patient survival after LT. METHODOLOGY/PRINCIPAL FINDINGS: One hundred and twenty-six LT candidates with acute-on-chronic hepatitis B liver failure and MELD score ≥30 were included in this prospective study. Of the 126 patients, 42 received emergency LT within 72 h (ELT group and the other 84 were given ALSS as salvage treatment. Of the 84 patients, 33 were found to have reduced MELD score (40 years and the interval from last ALSS to LT >48 h were independent negative influence factors of downgrading MELD. CONCLUSIONS/SIGNIFICANCE: Downgrading MELD for liver transplant candidates with MELD score ≥30 was effective in improving patient prognosis. An appropriate ALSS treatment within 48 h prior to LT is potentially beneficial.

    Previously, the livers of patients suffering from acute liver failure (ALF), a potentially fatal syndrome arising from infection by Hepatitis B Virus (HBV), were found to contain massive amounts of an antibody specific for the core antigen (HBcAg) capsid. We have used cryo-electron microscopy and molecular modeling to define its epitope. HBV capsids are icosahedral shells with 25Å-long dimeric spikes, each a 4-helix bundle, protruding from the contiguous "floor". Of the anti-HBcAg antibodies previously characterized, most bind around the spike tip while one binds to the floor. The ALF-associated antibody binds tangentially to a novel site on the side of the spike. This epitope is conformational. The Fab binds with high affinity to its principal determinants but has lower affinities for quasi-equivalent variants. The highest occupancy site is on one side of a spike, with no detectable binding to the corresponding site on the other side. Binding of one Fab per dimer was also observed by analytical ultracentrifugation. The Fab did not bind to the e-antigen dimer, a non-assembling variant of capsid protein. These findings support the propositions that antibodies with particular specificities may correlate with different clinical expressions of HBV infection and that antibodies directed to particular HBcAg epitopes may be involved in ALF pathogenesis.

    AIM: We report a case with a prolonged course of hepatitisA, with alanine aminotransferase (ALT) higher than 500 IU/Lfor more than 2 mo.METHODS: A middle-aged woman had an elevated IgG level of more than 2 000 mg/dL, positive arti-nudear antibodies (ANA) and anti-smooth muscle antibodies (ASMA), but no evidence of persistent hepatitis A virus (HAV) infection. Liver biopsy findings were compatible with prolonged acute hepatitis, although acute onset of autoimmune hepatitis could not be ruled out.RESULTS: It was assumed that she developed a course of hepatitis similar to autoimmune hepatitis triggered by HAV infection. Ursodeoxycholic acid (UDCA) treatment was initiated and a favorable outcome was obtained. CONCLUSION: We describe a case of a middle-aged woman who showed a prolonged course of acute hepatitis A mimicking autoimmune hepatitis. Treatment with UDCAproved to be effective.

    At present, there is no ideal model for predicting the short-term outcome of patients with acute-on-chronic hepatitis B liver failure (ACHBLF). This study aimed to establish and validate a prognostic model by using the classification and regression tree (CART) analysis. A total of 1047 patients from two separate medical centres with suspected ACHBLF were screened in the study, which were recognized as derivation cohort and validation cohort, respectively. CART analysis was applied to predict the 3-month mortality of patients with ACHBLF. The accuracy of the CART model was tested using the area under the receiver operating characteristic curve, which was compared with the model for end-stage liver disease (MELD) score and a new logistic regression model. CART analysis identified four variables as prognostic factors of ACHBLF: total bilirubin, age, serum sodium and INR, and three distinct risk groups: low risk (4.2%), intermediate risk (30.2%-53.2%) and high risk (81.4%-96.9%). The new logistic regression model was constructed with four independent factors, including age, total bilirubin, serum sodium and prothrombin activity by multivariate logistic regression analysis. The performances of the CART model (0.896), similar to the logistic regression model (0.914, P=.382), exceeded that of MELD score (0.667, P<.001). The results were confirmed in the validation cohort. We have developed and validated a novel CART model superior to MELD for predicting three-month mortality of patients with ACHBLF. Thus, the CART model could facilitate medical decision-making and provide clinicians with a validated practical bedside tool for ACHBLF risk stratification.

    In 2011, the Intractable Liver Diseases Study Group of Japan, established novel diagnostic criteria for "acute liver failure ", and published the classification criteria for the etiologies of acute liver failure and late-onset hepatic failure (LOHF) in 2013. According to this classification, HBV carriers showing acute hepatitis exacerbation were divided into 3 subgroups; asymptomatic or inactive HBV carriers without drug exposure, asymptomatic or inactive HBV carriers developing HBV reactivation during and after immunosuppressive therapies and/or antineoplastic chemotherapies and those with previously resolved HBV infection showing iatrogenic HBV reactivation. In an annual nationwide survey in 2013, however, a patient with previously resolved HBV infection was enrolled, in whom LOHF developed as a result of HBV reactivation despite in the absence of immunosuppressive therapies and/or antineoplastic chemotherapies. Thus, the study group revised the classification criteria in 2015; HBV carriers developing acute hepatitis exacerbation were classified into asymptomatic or inactive HBV carriers and patients with previously resolved HBV infection, and both groups were further sub-classified into those receiving immunosuppressive therapies and/or antineoplastic chemotherapies and those without such drugs exposure.

Demographic,biochemical and severity indexes,and treatment and outcome were assessed.RESULTS: Among the 11 patients, with a median age of 31 years, 72% had inflammatory response syndrome, and six patients received corticosteroids.The mortality rate within four weeks was 56%, and the one-year survival was 27%. In the survivors, severity indexes were lower and 83% received corticosteroids.CONCLUSION:We observed a relatively high survival rate in patients with acute liver failure due to autoimmune hepatitis. This survival rate could be influenced by severity of the disease and/or use of corticosteroids.

    The impact of chronic hepatitis B on the clinical outcome of acute hepatitis A remains controversial. The aim of present study was to evaluate the clinical characteristics of acute hepatitis A in cases with underlying chronic hepatitis B compared to cases of acute hepatitis A alone. Data on 758 patients with acute hepatitis A admitted at two university-affiliated hospitals were reviewed. Patients were classified into three groups: group A, patients with both acute hepatitis A and underlying chronic hepatitis B (n = 27); group B, patients infected by acute hepatitis A alone whose sexes and ages were matched with patients in group A (n  = 54); and group C, patients with acute hepatitis A alone (n = 731). None of the demographic features of group A were significantly different from those of group B or C, except for the proportion of males and body weight, which differed from group C. When comparing to group B, clinical symptoms were more frequent, and higher total bilirubin and lower albumin levels were observed in group A. When comparing to group C, the albumin levels were lower in group A. There were no differences in the duration of hospital stay, occurrence of acute kidney injury, acute liver failure, prolonged cholestasis, or relapsing hepatitis. This study revealed that clinical symptoms and laboratory findings were less favorable for patients with acute hepatitis A and chronic hepatitis B compared to those with acute hepatitis A alone. However, there were no differences in fatal outcomes or serious complications.

    Orlistat was approved by the Food and Drug Administration in 1998 and has been shown to be superior to placebo in achieving weight loss. It is generally well tolerated. However, severe liver injury has been reported. We present a case of hepatic failure in a patient taking orlistat. A 54-year-old African-American woman with hypertension presented with hepatic failure. She had noticed increasing fatigue, jaundice and confusion. She used alcohol sparingly and denied tobacco or illicit drug use, but had been taking over-the-counter orlistat for the past two months. Physical examination revealed scleral icterus, jaundice, asterixis and slow speech. Laboratory testing showed markedly abnormal liver function tests with coagulopathy. Acute viral and autoimmune serologies were negative, as was toxicology screen. Liver biopsy showed necrotic hepatic parenchyma likely secondary to drug toxicity. Based upon her clinical presentation and time course, the pattern of liver injury seen on liver biopsy and lack of an alternative plausible explanation, her liver failure was most likely associated with orlistat use. She continued to deteriorate and ultimately underwent orthotopic liver transplantation. Fourteen cases of severe liver injury associated with orlistat use have been reported, four of which are detailed in the literature. This is the second published case of liver failure associated with over-the-counter orlistat usage. Clinicians should be aware of the growing number of cases associating liver injury and orlistat use and carefully monitor their patients on this medication for signs of hepatic dysfunction.

    Here, we explored protective effects of protostemonine (PSN), on mouse acute liver failure induced by lipopolysaccharide/d-galactosamine (LPS/GalN). PSN dose-dependently declined LPS/GalN-induced lethality of mice as well as increase of ALT/AST activities in their serum. Hepatoprotective effects of PSN were also supported by liver histopathological examinations. After LPS/GalN treatment, severe oxidative stresses in the liver could be detected by boosted MDA and ROS as well as decreased GSH. Moreover, hepatic expression of pro-inflammatory cytokines, including TNF-α, IL-1β and IL-6, were sharply elevated. These symptoms were dose-dependently ameliorated by PSN. Mechanistically, PSN promoted the transcription and translation of heme oxygenase-1 (HO-1) in hepatocytes and liver Kupffer cells. Nrf2 is a master transcription factor contributing to the expression of HO-1. PSN elevated Nrf2 nuclear accumulation and enhanced Nrf2/HO-1 promoter interaction. Suppressing enzyme activity of HO-1 by co-treating mice with HO-1 inhibitor ZnPP abolished protective effects of PSN. ZnPP also abrogated alleviative impacts of PSN on LPS/GalN-mediated hepatic oxidative stresses and inflammatory responses. Finally, we showed that PSN exhibited undetectable toxic effects on vital organs of mice. Our findings suggested that PSN is able to attenuate LPS/GalN-induced acute liver failure and upregulating HO-1 expression is implicated in its hepatoprotective activity.

    Full Text Available High doses of acetaminophen (APAP; N-acetyl-p-aminophenol cause severe hepatotoxicity after metabolic activation by cytochrome P450 2E1. This study was undertaken to examine the preventive effects of thiacremonone, a compound extracted from garlic, on APAP-induced acute hepatic failure in male C57BL/6J. Mice received with 500 mg/kg APAP after a 7-day pretreatment with thiacremonone (10–50 mg/kg. Thiacremonone inhibited the APAP-induced serum ALT and AST levels in a dose-dependent manner, and markedly reduced the restricted area of necrosis and inflammation by administration of APAP. Thiacremonone also inhibited the APAP-induced depletion of intracellular GSH, induction of nitric oxide, and lipid peroxidation as well as expression of P450 2E1. After APAP injection, the numbers of Kupffer cells, natural killer cells, and cytotoxic T cells were elevated, but the elevated cell numbers in the liver were reduced in thiacremonone pretreated mice. The expression levels of I-309, M-CSF, MIG, MIP-1α, MIP-1β, IL-7, and IL-17 were increased by APAP treatment, which were inhibited in thiacremonone pretreated mice. These data indicate that thiacremonone could be a useful agent for the treatment of drug-induced hepatic failure and that the reduction of cytotoxic immune cells as well as proinflammatory cytokine production may be critical for the prevention of APAP-induced acute liver toxicity.

RECENT FINDINGS: Neutrophil gelatinase-associated lipocalin appears to be a sensitive, specific and reliable biomarker of renal injury, which may be predictive of renal outcome in the perioperative setting. For estimation of glomerular filtration rate, cystatin C is superior to creatinine. No drug is definitively effective at preventing postoperative renal failure. Clinical trials of fenoldopam and atrial natriuretic peptide are, at best, equivocal. As with pharmacological preconditioning of the heart, volatile anaesthetic agents appear to offer a protective effect to the subsequently ischaemic kidney. SUMMARY: Although a greatly improved understanding of the pathophysiology of acute renal failure has offered even more therapeutic targets, the maintenance of intravascular euvolaemia and perfusion pressure is most effective at preventing new postoperative acute renal failure. In the future, strategies targeting renal regeneration after injury will use bone marrow-derived stem cells and growth factors such as insulin-like growth factor-1.

    Acute liver failure, also known as fulminant hepatic failure (FHF), embraces a spectrum of clinical entities characterized by acute liver injury, severe hepatocellular dysfunction, and hepatic encephalopathy. Cerebral edema and intracranial hypertension are common causes of mortality in patients with FHF. The management of patients who present acute liver failure starts with determining the cause and an initial evaluation of prognosis. Regardless of whether or not patients are listed for liver transplantation, they should still be monitored for recovery, death, or transplantation. In the past, neuromonitoring was restricted to serial clinical neurologic examination and, in some cases, intracranial pressure monitoring. Over the years, this monitoring has proven insufficient, as brain abnormalities were detected at late and irreversible stages. The need for real-time monitoring of brain functions to favor prompt treatment and avert irreversible brain injuries led to the concepts of multimodal monitoring and neurophysiological decision support. New monitoring techniques, such as brain tissue oxygen tension, continuous electroencephalogram, transcranial Doppler, and cerebral microdialysis, have been developed. These techniques enable early diagnosis of brain hemodynamic, electrical, and biochemical changes, allow brain anatomical and physiological monitoring-guided therapy, and have improved patient survival rates. The purpose of this review is to discuss the multimodality methods available for monitoring patients with FHF in the neurocritical care setting.

    Acute-on-chronic liver failure (ACLF) is a distinct entity that differs from acute liver failure and decompensated cirrhosis in timing, presence of treatable acute precipitant, and course of disease, with a potential for self-recovery. The core concept is acute deterioration of existing liver function in a patient of chronic liver disease with or without cirrhosis in response to an acute insult. The insult should be a hepatic one and presentation in the form of liver failure (jaundice, encephalopathy, coagulopathy, ascites) with or without extrahepatic organ failure in a defined time frame. ACLF is characterized by a state of deregulated inflammation. Initial cytokine burst presenting as SIRS, progression to CARS and associated immunoparalysis leads to sepsis and multi-organ failure. Early identification of the acute insult and mitigation of the same, use of nucleoside analogue in HBV-ACLF, steroid in severe alcoholic hepatitis, steroid in severe autoimmune hepatitis and/or bridging therapy lead to recovery, with a 90-day transplant-free survival rate of up to 50 %. First-week presentation is crucial concerning SIRS/sepsis, development, multiorgan failure and consideration of transplant. A protocol-based multi-disciplinary approach including critical care hepatology, early liver transplant before multi-organ involvement, or priority for organ allocation may improve the outcome. Presentation with extrahepatic organ involvement or inclusion of sepsis as an acute insult in definition restricts the therapy, i.e., liver transplant or bridging therapy, and needs serious consideration. Augmentation of regeneration, cell-based therapy, immunotherapy, and gut microbiota modulation are the emerging areas and need further research.

    Carmen Unzu

    Full Text Available Chronic kidney disease is a long-term complication in acute intermittent porphyria (AIP. The pathophysiological significance of hepatic overproduction of the porphyrin precursors aminolevulinate acid (ALA and porphobilinogen (PBG in chronic kidney disease is unclear. We have investigated the effect of repetitive acute attacks on renal function and the effect of total or five-sixth nephrectomy causing renal insufficiency on hepatic heme synthesis in the porphobilinogen deaminase (PBGD-deficient (AIP mouse. Phenobarbital challenge in the AIP-mice increased urinary porphyrin precursor excretion. Successive attacks throughout 14 weeks led to minor renal lesions with no impact on renal function. In the liver of wild type and AIP mice, 5/6 nephrectomy enhanced transcription of the first and rate-limiting ALA synthase. As a consequence, urinary PBG excretion increased in AIP mice. The PBG/ALA ratio increased from 1 in sham operated AIP animals to over 5 (males and over 13 (females in the 5/6 nephrectomized mice. Total nephrectomy caused a rapid decrease in PBGD activity without changes in enzyme protein level in the AIP mice but not in the wild type animals. In conclusion, high concentration of porphyrin precursors had little impact on renal function. However, progressive renal insufficiency aggravates porphyria attacks and increases the PBG/ALA ratio, which should be considered a warning sign for potentially life-threatening impairment in AIP patients with signs of renal failure.

    2008-08-01

    Full Text Available Abstract Introduction Primary hepatic lymphoma is an unusual form of non-Hodgkin's lymphoma that usually presents with constitutional symptoms, hepatomegaly and signs of cholestatic jaundice. Diffuse hepatic infiltration is uncommon and presentation with acute hepatic failure even more rare. The presence of markedly elevated ferritin levels can complicate the evaluation process and suggest alternative diagnoses. We present the case of a middle-aged woman exhibiting pancytopenia, hyperferritinemia and rapidly deteriorating to develop acute hepatic failure. Her initial clinical picture led to a working diagnosis of adult onset Still's disease with probable hemophagocytic syndrome before her worsening liver function necessitated a percutaneous liver biopsy and establishment of the final diagnosis of primary hepatic lymphoma. Conclusion Primary hepatic lymphoma is an uncommon malignancy and its manifestation as progressive hepatitis or acute fulminant hepatic failure can be difficult to diagnose. The presence of constitutional symptoms, pancytopenia and high ferritin levels can complicate the evaluation process. A liver biopsy early in the course of liver dysfunction may establish the diagnosis without a higher risk of bleeding complications seen once liver failure sets in.

    The patient was a 57-year-old woman presenting with jaundice as the chief complaint. She began vomiting on July 10, 2003.Jaundice was noted and admitted to our hospital for thorough testing. Tests on admission indicated severe hepatitis, based on: aspartate aminotransferase (AST), 1 076 IU/L; alanine aminotransferase (ALT), 1 400 IU/L; total bilirubin (TB), 20.9 mg/dL; and prothrombin time rate (PT%), 46.9%. Acute hepatitis A (HA) was diagnosed based on negative hepatitis B surface antigen and hepatitis C virus RNA and positive immunoglobulin (Ig) M HA antibody, but elevation of anti-nuclear antigen (×320) and IgG (3 112 mg/dL) led to suspicion of autoimmune hepatitis (AIH). Plasma exchange was performed for 3 d from July 17, and steroid pulse therapy was performed for 3 d starting on July 18, followed by oral steroid therapy. Liver biopsy was performed on August 5, and the results confirmed acute hepatitis and mild chronic inflammation. Levels of AST and ALT normalized,so dose of oral steroid was markedly reduced. Steroid therapy was terminated after 4 mo, as the patient had glaucoma. Starting 3 mo after cessation of steroid therapy,levels of AST and ALT began to increase again. Another liver biopsy was performed and AIH was diagnosed based on serum data and biopsy specimen. Oral steroid therapy was reinitiated. Levels of AST and ALT again normalized.The present case was thus considered to represent AIH triggered by acute HA.

    Introduction: The purpose of this study is to determine the etiologies, histopathology and MDCT findings of children with fulminant hepatic failure admitted to our institution. Materials and methods: Between June 2004 and November 2006, 15 children with fulminant hepatic failure who underwent MDCT were included retrospectively in this study. Twelve patients had liver biopsies. The patients were divided into three groups as hyperacute (Group I), acute (Group II) and subacute (Group III) depending on onset of hepatic encephalopathy. Results: Hepatitis A in 4 patients, non-A, non-E hepatitis in 4; mushroom poisoning in 3; fulminant Wilson's disease in 2; autoimmune hepatitis in 1; and both hepatitis B and toxic hepatitis (with leflunomide treatment) in 1 patient were detected. MDCT of all three groups revealed diffuse reduction in hepatic attenuation in 11 patients; ascites in 9; periportal edema in 6; edema of gallbladder wall in 6; splenomegaly in 6; heterogeneous hepatic parenchyma in 6; hepatomegaly in 3; irregular contours of liver in 2; multiple micronodules in 1 and necrotic areas and regeneration in liver parenchyma in 2 patients. Histopathologic evaluation of liver biopsies showed massive hepatic necrosis, inflammatory cell infiltration and ductular proliferation in 8 patients, periportal edema in 6, edema of gallbladder wall in 5, regenerating nodules and fibrous septa consistent with cirrhotic pattern in 2, and regenerating nodules and necrotic areas in 2 patients. Conclusion: The most common MDCT findings in fulminant hepatic failure were diffuse reduction in hepatic attenuation and ascites. Massive hepatic necrosis was the most common histopathologic finding.

    Background Acute-on-chronic hepatitis B liver failure (ACLF-HBV) is a clinically severe disease associated with major life-threatening complications including hepatic encephalopathy and hepatorenal syndrome.The aim of this study was to evaluate the short-term prognostic predictability of the model for end-stage liver disease (MELD),MELD-based indices,and their dynamic changes in patients with ACLF-HBV,and to establish a new model for predicting the prognosis of ACLF-HBV.Methods A total of 172 patients with ACLF-HBV who stayed in the hospital for more than 2 weeks were retrospectively recruited.The predictive accuracy of MELD,MELD-based indices,and their dynamic change (△) were compared using the area under the receiver operating characteristic curve method.The associations between mortality and patient characteristics were studied by univariate and multivariate analyses.Results The 3-month mortality was 43.6%.The largest concordance (c) statistic predicting 3-month mortality was the MELD score at the end of 2 weeks of admission (0.8),followed by the MELD:sodium ratio (MESO) (0.796) and integrated MELD (iMELD) (0.758) scores,△MELD (0.752),△MESO (0.729),and MELD plus sodium (MELD-Na) (0.728) scores.In multivariate Logistic regression analysis,the independent factors predicting prognosis were hepatic encephalopathy (OR=-3.466),serum creatinine,international normalized ratio (INR),and total bilirubin at the end of 2 weeks of admission (OR=10.302,6.063,5.208,respectively),and cholinesterase on admission (OR=0.255).This regression model had a greater prognostic value (c=0.85,95% Cl 0.791-0.909) compared to the MELD score at the end of 2 weeks of admission (Z=4.9851,P=-0.0256).Conclusions MELD score at the end of 2 weeks of admission is a useful predictor for 3-month mortality in ACLF-HBV patients.Hepatic encephalopathy,serum creatinine,international normalized ratio,and total bilirubin at the end of 2 weeks of admission and cholinesterase on admission are

    Acute-on-chronic liver failure (ACLF) is a distinct clinical entity and differs from acute liver failure and decompensated cirrhosis in timing, presence of acute precipitant, course of disease and potential for unaided recovery. The definition involves outlining the acute and chronic insults to include a homogenous patient group with liver failure and an expected outcome in a specific timeframe. The pathophysiology of ACLF relates to persistent inflammation, immune dysregulation with initial wide-spread immune activation, a state of systematic inflammatory response syndrome and subsequent sepsis due to immune paresis. The disease severity and outcome can be predicted by both hepatic and extrahepatic organ failure(s). Clinical recovery is expected with the use of nucleoside analogues for hepatitis B, and steroids for severe alcoholic hepatitis and, possibly, severe autoimmune hepatitis. Artificial liver support systems help remove toxins and metabolites and serve as a bridge therapy before liver transplantation. Hepatic regeneration during ongoing liver failure, although challenging, is possible through the use of growth factors. Liver transplantation remains the definitive treatment with a good outcome. Pre-emptive antiviral agents for hepatitis B before chemotherapy to prevent viral reactivation and caution in using potentially hepatotoxic drugs can prevent the development of ACLF.

    Fulminant hepatic failure (FHF), also known as fulminant hepatitis, is a rare and extremely serious condition with a high mortality rate. Its rapid evolution and complexity in managing the treatment, creates the need to provide some immediate care by a team that specialises in intensive care. This acute decompensation is usually associated with other disorders, such as coagulopathy and hepatic encephalopathy, being responsible for major complications that can lead to organ failure. In our region the most common origin is unknown, followed by acute infection with hepatitis B. The treatment of this syndrome is based on the general measures applicable to any critically ill patient: treat the cause and early detection of extrahepatic complications, urgent liver transplantation being one of the alternatives with a better prognosis. This article presents a case report describing the monitoring of an Irish woman of 20 years who was transferred from a hospital in Ibiza to a hospital in Barcelona, with a suspected diagnosis of FHF. Following the conceptual model of Virginia Henderson, the collaborative problems and nursing diagnoses are described, presenting a care plan according to NANDA (North American Nursing Association), NIC (Nursing Intervention Classification), NOC (Nursing Outcomes Classification). This case helps to establish an individualised care plan that provides guidance to nurse professionals in critical patient care by increasing the knowledge of FHF.

    Introduction Hepatic injury of varied aetiology may progress to Acute Liver Failure (ALF). Compromised microcirculation is thought to be a deciding factor of hepatic hypoxia may be involved in disease progression that needs early detection. Ischaemia markers like serum Ischaemia- modified albumin (IMA), ALT-LDH ratio and ALT-LDH index have been suggested for its detection at early stage. Aim To find out the association of Ischaemia markers like serum IMA, ALT-LDH ratio and ALT-LDH index in acute hepatic injury cases. Materials and Methods Forty one diagnosed acute liver injury cases of varied aetiology admitted in Department of Medicine, and Gastroenterology of SCB Medical College, Cuttack were enrolled in the study along with 30 age and sex matched healthy controls. Blood collected at time of admission and at time of discharge (1st day and 7th day) were evaluated for FPG, RFT, LFT, Serum Albumin along with serum LDH, IMA, PT-INR and platelet count. Result Serum bilirubin, hepatic enzymes, IMA, PT-INR was more markedly raised in cases than controls on the 1st day of admission. ALT-LDH ratio and index were significantly low in complicated cases. However, on responding to treatment the ALT-LDH index on 7th day registered a rise in comparison to the 1st day, while serum IMA revealed an insignificant decline showing improvement in hepatic hypoxia. ALT-LDH ratio remains more or less same on response to treatment. Conclusion Serum IMA and ALT-LDH Index reveals association with disease process in Acute Hepatic Injury cases both clinically and biochemically and can be used as supportive parameters for the diagnosis of disease process.

    Propylthiouracil- (PTU-) induced hepatotoxicity is rare but potentially lethal with a spectrum of liver injury ranging from asymptomatic elevation of transaminases to fulminant hepatic failure and death. We describe two cases of acute hepatic failure due to PTU that required liver transplantation. Differences in the clinical presentation, histological characteristics, and posttransplant management are described as well as alternative therapeutic options. Frequent monitoring for PTU-induced hepatic dysfunction is strongly advised because timely discontinuation of this drug and implementation of noninvasive therapeutic interventions may prevent progression to liver failure or even death.

    Seven episodes of rhabdomyolysis with acute renal failure (ARF) have been observed in 6 patients treated with various short-acting tranquilizers and antidepressants. Clinical features usually included severe hyperthermia, diffuse hypertonicity with or without coma, circulatory failure or unstable blood pressure, and often acute respiratory failure. Serum CPK were always elevated. The type of ARF was prerenal failure without oliguria in 5/7 episodes, and acute tubular necrosis in 2/7 episodes, requiring hemodialyses in one patient. Three patients died. In any case, the tranquilizers and antidepressants responsible for this syndrome were stopped, and electrolyte disorders and acidosis were corrected. Associated acute circulatory failure, septicemia and/or acute hepatic failure required prompt therapy, and artificial ventilation was required in 4 instances. The further use of phenothiazines, butyrophenones, sulpiride and their derivatives should be avoided in any patient having developed such an accident, whose pathophysiology is similar to that described in malignant hyperthermia of various origin.

    2007-01-01

    Imatinib mesylate is a drug that has been approved for treatment of chronic myeloid leukemia (CML) in blast crisis, accelerated or chronic phase, and also for advanced gastrointestinal stromal tumors. Severe hepatic toxicity and three deaths from hepatic failure have been reported. We report the case of a 51-year-old woman who was admitted to our institution with severe acute hepatitis. She was diagnosed with CML and began treatment with imatinib mesylate at a dose of 400 mg/d.Five months after beginning treatment, she developed severe hepatitis associated with coagulopathy, and was admitted to our institution. She had been consuming acetaminophen 500-1000 mg/d after the onset of symptoms. She had a progressive increase in bilirubin level and a marked decrease of clotting factor Ⅴ. Five days after admission, grade Ⅱ encephalopathy developed and she was referred for liver transplantation. Her clinical condition progressively deteriorated, and 48 h after being referred for transplantation she suffered a cardiac arrest and died. This report adds concern about the possibility of imatinib-mesylate-induced hepatotoxicity and liver failure, particularly in the case of concomitant use with acetaminophen. Liver function tests should be carefully monitored during treatment and, with the appearance of any elevation of liver function tests, treatment should be discontinued.

Other evaluations included a normal toxicology screen and negative acetaminophen level. Autoimmune and infectious workups were normal providing no identifiable cause of his acute liver failure. He initially denied any ingestions or illicit drug use but on further query he admitted taking niacin in an attempt to obscure the results of an upcoming drug test. Niacin has been touted on the Internet as an aid to help pass urine drug tests though there is no evidence to support this practice. Niacin toxicity has been associated with serious multisystem organ failure and fulminant hepatic failure requiring liver transplantation. Pediatric providers should be aware of the risks associated with niacin toxicity and other experimental medical therapies that may be described on the Internet or other nonreputable sources.

    Full Text Available Hepatitis E infection is an important cause of fulminant hepatic failure (FHF in pregnancy in developing countries like India, with a high mortality rate. It is postulated that immunological and hormonal changes in pregnant women predispose them to developing FHF secondary to hepatitis E infection as compared to the less severe form seen in the non-pregnant population. A variation in the natural course of the disease is also seen amongst different geographical areas. Hepatitis E infection is seen to be less severe in parts of the world like Egypt, Europe and the USA as against the Indian subcontinent. The mainstay of management of acute viral hepatitis (AVH and fulminant hepatic failure secondary to hepatitis E virus is supportive treatment. Since an increased severity of the disease is associated with the pregnant state, termination of pregnancy to alter its course is an option worth considering. Our case study showed promising results of induction of labour in a case of FHF (hepatic encephalopathy with disseminated intravascular coagulation caused by hepatitis E, in the third trimester of pregnancy.

    Parvovirus B19 induced acute hepatitis and hepatic failure have been previously reported,mainly in children.Very few cases of parvovirus induced hepatic failure have been reported in adults and fewer still have required liver transplantation.We report the case of a 55-year-old immunocompetent woman who developed fulminant hepatic failure after acute infection with Parvovirus B19 who subsequently underwent orthotopic liver transplantation.This is believed to be the first reported case in the literature in which an adult patient with fulminant hepatic failure associated with acute parvovirus B19 infection and without hematologic abnormalities has been identified prior to undergoing liver transplantation.This case suggests that Parvovirus B19 induced liver disease can affect adults,can occur in the absence of hematologic abnormalities and can be severe enough to require liver transplantation.

    急性乙型肝炎并发肾功能衰竭十分少见,其肝外表现通常为血清病样表现,包括发热、皮疹和多动脉炎.我们报道1位男性34岁患者,诊断为急性HBV感染,临床表现为肝脏和肝外多器官的损害,以肾功能衰竭为突出的表现,推测是由循环免疫复合物沉积在肾小球血管壁,导致膜性肾小球肾炎而引起的.患者接受了血液透析和持续性血液滤过治疗、常规的护肝和对症治疗及恩替卡韦抗病毒治疗,最后痊愈.%Acute hepatitis B is often accompanied by serum-sickness-like syndrome, including fever, rash and polyarteritis. Acute renal failure in acute hepatitis B is extremely rare. A 34-year-old male presented to our hospital, with initial laboratory values showing acute hepatitis B virus infection. The clinical feature indicated hepatitis and extrahepatic impairments of kidney, myocardium and platelet, and renal failure was the prominent manifestation which appeared early in the day 3 of onsetting, including 19 days of oliguria and 6 days of anuria. Kidney impairment was presumed owing to deposition of immune complex which resulted in membranous glomerulonephritis. The patient accepted hemodialysis and continuous renal replacement therapy, and entecavir was applied to depress HBV DNA copying and may have shortened the course of the disease. At 2-month follow up, the patient healed completely.

    Acute hepatic encephalopathy is a poorly defined syndrome of heterogeneous aetiology. We report a 49-year-old woman with alcoholic cirrhosis and hereditary haemorrhagic telangiectasia who developed acute hepatic coma induced by severe gastrointestinal bleeding. Laboratory analysis revealed excessively elevated blood ammonia. MRI showed lesions compatible with chronic hepatic encephalopathy and widespread cortical signal change sparing the perirolandic and occipital cortex. The cortical lesions resembled those of hypoxic brain damage and were interpreted as acute toxic cortical laminar necrosis. (orig.)

    Full Text Available A 65-year-old Taiwanese man presented with dark urine for 5 days before admission to hospital and with fever on the 2nd day of admission to hospital. Laboratory studies showed acute hepatitis with hyperbilirubinemia. Acute hepatitis with nontyphoidal salmonella and hepatitis E virus coinfection was diagnosed. The fever subsided after treatment with ceftriaxone and cefepime. His serum bilirubin reached its peak value on the 3rd week after admission to hospital and then gradually returned to the normal range. To the best of our knowledge, acute hepatitis E coinfection with nontyphoidal salmonella has not been reported previously.

    We report a case of fatal fulminant hepatic failure related to the use of disulfiram. This is a commonly used medication; however there are few reported cases in the medical literature of fatal liver failure related to its use. Patients using disulfiram for alcohol cessation typically have multiple risk factors for liver disease and are not acutely candidates for orthotopic liver transplant due to recent alcohol dependence. This case demonstrates a rare adverse reaction to a commonly used medication with a fatal outcome. Our patient was a sixty-six year old man who had recently started using disulfiram for the purpose of alcohol cessation. He developed hepatotoxicity that progressed to fulminant hepatic failure. Despite cessation of the medication and supportive care, the outcome was fatal.

  14. Acute hepatitis C: Prospects and challenges

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    More than 170 million people worldwide have chronic hepatitis C. Acute hepatitis C is rarely diagnosed because it is commonly asymptomatic. Most infected patients are unaware of their condition until the symptoms of chronic infection manifest. Treatment of acute hepatitis C is something of a paradox because spontaneous resolution is possible and many patients do not have symptoms.However, several factors provide a rationale for treating patients who have acute hepatitis C. Compared with acute hepatitis C, chronic hepatitis C is associated with a worse prognosis, the need for more intensive treatment,longer treatment duration, and a decrease in successful treatment outcomes. Conversely, early intervention is associated with improved viral eradication, using a regimen that is better tolerated, less expensive, more convenient, and of shorter duration than the currently approved combination therapies for chronic hepatitis C.

    Millions of Americans regularly use herbal supplements, but many are unaware of the potential hidden dangers. Numerous supplements have been associated with hepatotoxicity and, indeed dietary/herbal supplements represent an increasingly common source of acute liver injury. We report a case of acute liver failure requiring liver transplantation associated with the use of Garcinia cambogia, a supplement widely promoted for weight loss. When patients present with acute hepatitis or liver failure from an unknown etiology, a careful history of supplement use should be performed.

    Tetrachloroethylene is a chlorinated solvent that is primarily used in dry cleaning and degreasing operations. Although the hepatotoxicity caused by tetrachloroethylene has been well documented in literature, it is rarely considered as a cause of acute liver failure. We report a case of a 39-yr-old man who was admitted to our hospital for acute liver failure due to tetrachloroethylene exposure. Histological examination of the liver revealed massive hepatic necrosis, prominently, in zone 3 of the hepatic lobules. The patient underwent supportive treatment along with 3 sessions of plasmapheresis, and consequently, he presented a favorable outcome. Repeat liver biopsy performed 6 months after the patient's discharge showed architectural distortion with postnecrotic cirrhosis. Physicians should be aware of the possibility of acute liver failure induced by tetrachloroethylene. Early plasmapheresis can be effective for individuals with sufficient capacity for hepatocyte regeneration.

    2009-01-01

    BACKGROUND: Chronic hepatitis B virus (HBV) infection remains a major global health issue, and the prognosis of patients with HBV-associated fulminant hepatic failure is extremely poor. The application of antiviral therapies has led to signiifcant improvements in patient outcomes. This article aimed to review the current strategies in antiviral treatment of HBV-associated fulminant hepatic failure. DATA SOURCES: Literature search was conducted using PubMed on the related subjects. Part of the data was from the most recent work of the authors' laboratory. RESULTS: Hepatitis B immunoglobulin in prevention of recurrent HBV infection after orthotopic liver transplantation (OLT) has been proven effective. However, its cost is high, and signiifcant side effects have been found to induce viral mutations. Lamivudine has a potent suppression for HBV replication and an excellent safety proifle in decompensated cirrhotic patients, but its major drawback is the high rate of drug-resistance. Adefovir is effective for lamivudine-resistance strains in the post-OLT situation, and its drug-resistance rate is relatively low. Combination therapies such as hepatitis B immunoglobulin combined with lamivudine and lamivudine combined with adefovir have been widely adopted for prophylaxis against HBV recurrence of infection after OLT. Entecavir, telbivudine, tenofovir and other newer agents have been widely used in antiviral therapy. CONCLUSIONS: The prognosis of HBV-associated ful-minant hepatic failure is being transformed by developments in antiviral therapy. However, it should be noticed that HBV is controlled but never eliminated, and drug-resistance still remains a major issue. Hopefully, newer strategies may help to solve these problems.

    Herpes hepatitis is a rare cause of fulminant hepatic failure contributing to less than 1% of all cases. It is most often seen in persons who are immunosuppressed and in pregnant women. The presentation is usually non-specific and rapidly progressive, thus making antemortem diagnosis of this condition rare. We present a patient who was on chronic immunosuppressive therapy for systemic lupus erythematosus and subsequently developed multi-organ failure with anicteric transaminitis as a result of disseminated herpes infection. The diagnosis was only made post-mortem. A confounding factor in this case was the fact that the patient underwent plasmapheresis, which skewed the interpretation of liver function tests in the setting of acute liver failure.

    Hepatic encephalopathy (HE) is associated with cerebral edema (CE), increased intracranial pressure (ICP), and subsequent neurologic complications; it is the most important cause of morbidity and mortality in fulminant hepatic failure. The goal of therapy should be early diagnosis and treatment of HE with measures to reduce CE. A combination of clinical examination and diagnostic modalities can aid in prompt diagnosis. ICP monitoring and transcranial Doppler help diagnose and monitor response to treatment. Transfer to a transplant center and intensive care unit admission with airway management and reduction of CE with hypertonic saline, mannitol, hypothermia, and sedation are recommended as a bridge to liver transplantation.

    Hepatitis viral infection is hyperendemic in Egypt, western Asia and Africa. However, little is known about the status of hepatitis viruses among rural Egyptian children. Therefore, this study sought to examine the prevalence and characteristics of hepatitis viruses among symptomatic Egyptian children. Serological and molecular analyses of hepatitis viral infection were conducted in 33 children hospitalised at Mansoura University with symptomatic hepatic dysfunction (mean ± standard deviation age, 9.7±3.4 years; alanine aminotransferase level, 130±68 IU/ml). Eleven children (33%) were positive for anti-haemagglutination-IgM and were diagnosed with acute hepatitis A. Hepatitis B surface antigen (HBsAg) and anti‑hepatitis C virus (HCV) were detected in 9 (27%) and 7 (21%) children, respectively, indicating acute-on-chronic infection with hepatitis viruses. None of the children was positive for anti‑hepatitis B core antigen-IgM. Phylogenetic analysis confirmed that all HBVs belonged to genotype D (subgenotype D1) and that HCV belonged to genotypes 4a and 1g. HBV-DNA was detected in 9 children (27%) in the pre-S/S region and in 16 children (48%) in the core promoter/precore region. The Y134F amino acid mutation in the 'α' determinant region was detected in all of the patients. The A1762T/G1764A double mutation, and the T1846A and G1896A single mutations were common in children with occult HBV infection. In conclusion, hepatitis viral infection, including acute-on-chronic infection with HCV and HBV, is common in Egyptian children hospitalised with acute hepatitis.

  5. [Perioperative acute kidney injury and failure].

    2014-04-01

    Perioperative period is very likely to lead to acute renal failure because of anesthesia (general or perimedullary) and/or surgery which can cause acute kidney injury. Characterization of acute renal failure is based on serum creatinine level which is imprecise during and following surgery. Studies are based on various definitions of acute renal failure with different thresholds which skewed their comparisons. The RIFLE classification (risk, injury, failure, loss, end stage kidney disease) allows clinicians to distinguish in a similar manner between different stages of acute kidney injury rather than using a unique definition of acute renal failure. Acute renal failure during the perioperative period can mainly be explained by iatrogenic, hemodynamic or surgical causes and can result in an increased morbi-mortality. Prevention of this complication requires hemodynamic optimization (venous return, cardiac output, vascular resistance), discontinuation of nephrotoxic drugs but also knowledge of the different steps of the surgery to avoid further degradation of renal perfusion. Diuretics do not prevent acute renal failure and may even push it forward especially during the perioperative period when venous retourn is already reduced. Edema or weight gain following surgery are not correlated with the vascular compartment volume, much less with renal perfusion. Treatment of perioperative acute renal failure is similar to other acute renal failure. Renal replacement therapy must be mastered to prevent any additional risk of hemodynamic instability or hydro-electrolytic imbalance.

  7. Definition of ACLF and inclusion criteria for extra-hepatic organ failure.

    Science.gov (United States)

    Wang, Xiaojing; Sarin, Shiv Kumar; Ning, Qin

    2015-07-01

    A prominent characteristic of ACLF is rapid hepatic disease progression with subsequent extra-hepatic organ failure, manifesting as either hepatic coma or hepatorenal syndrome, which is associated with a high mortality rate in a short time. The APASL definition mainly emphasizes recognizing patients with hepatic failure. These patients may subsequently develop extra-hepatic multisystem organ failure leading to high mortality. It is therefore worthwhile to identify the short interim period between the development of liver failure and the onset of extra-hepatic organ failure, the potential therapeutic 'golden window.' Interventions during this period may prevent the development of complications and eventually change the course of the illness. Organ failure is suggested to be a central component of ACLF and may behave differently from chronic decompensated liver disease. Clear and practical criteria for the inclusion of organ failure are urgently needed so that patients with these life-threatening complications can be treated in a timely and appropriate manner. Recent studies suggested that the scoring systems evaluating organ failure [acute physiology, age and chronic health evaluation (APACHE) and sequential organ failure assessment (SOFA) scores] work better than those addressing the severity of liver disease [Child-Pugh and model of end-stage liver disease (MELD) scores] in ACLF. However, a key problem remains that the former scoring systems are reflective of organ failure and not predictive, thus limiting their value as an early indication for intervention.

    We report a case of fulminant hepatic failure associated with Salmonella paratyphi A infection, in a 29-yearold patient who was admitted to the intensive care unit (TCU) with fever of two days, headache and vomiting followed by behavioural changes and disorientation. On examination, the patient appeared acutely ill, agitated, confused, and deeply jaundiced. Temperature 38.5℃,pulse 92/min, blood pressure 130/89 mmHg. Both samples of blood grew S. paratyphi A, which was sensitive to ceftriaxone and ciprofioxacin. Ceftriaxon was administered with high-dose dexamethasone. Two weeks after treatment with ceftriaxon, the patient was discharged in satisfactory condition.

    Defects in the mitochondrial respiratory chain can induce a heterogeneous range of clinical and biochemical manifestations. Hepatic involvement includes acute fulminant hepatic failure, microvesicular steatosis, neonatal non-alloimmune haemochromatosis and cirrhosis. Recently pathogenic mutations in tRNA 5-methylaminomethyl-2-thiouridylate methyltransferase (TRMU) gene (OMIM 610230) have been demonstrated to cause transient infantile liver failure (OMIM 613070). The human TRMU gene encodes a mitochondrial protein, 5-methylaminomethyl-2-thiouridylate methyltransferase, whose molecular function is that of mitochondrial tRNA modification.We report an infant who presented with acute liver failure, in whom we observed hepatic copper intoxication and cirrhosis on liver biopsy. We postulate that the hepatic copper intoxication observed in our patient is most likely a secondary event associated with cholangiopathy. Periportal copper accumulation has been implicated in causing secondary mitochondrial dysfunction; the impact of copper accumulation in patients with TRMU mutations is unclear and warrants long-term clinical follow-up.

  14. Nutrition in acute renal failure

    Directory of Open Access Journals (Sweden)

    Sérgio Mussi Guimarães

    Full Text Available Nutritional status has been considered to be one of the possible determinants of mortality rates in cases of acute renal failure (ARF. However, most studies evaluating possible mortality indicators in ARF cases have not focused on the nutritional status, possibly because of the difficulties involved in assessing the nutritional status of critically ill patients. Although the traditional methods for assessing nutritional status are used for ARF patients, they are not the best choice in this population. The use of nutritional support for these patients has produced conflicting results regarding morbidity and mortality. This review covers the mechanisms and indicators of malnutrition in ARF cases and the types of nutritional support that may be used.

    BACKGROUND:Perioperative treatment of emergency liver transplantation for acute hepatic failure is extremely different from common liver transplantation, due to complex conditions, high risk, several complications, and high mortality. OBJECTIVE:To summarize the experience of emergency liver transplantation for acute hepatic failure during the perioperative period, and to increase the success rate in treatment of acute hepatic failure. METHODS:A retrospective analysis was undertaken on the clinical data of 38 cases undergone emergency liver transplantation for acute hepatic failure. There were 21 male and 17 female, who aged 15-69 years. Among them, 23 cases had hepatitis B virus (including 2 cases with hepatitis B and C virus), 7 cases had Wilsons disease, 3 cases had mushroom poisoning, 2 cases had unknown liver damage, 1 case had Tripterygium wilfordi poisoning, 1 case had decompensation after partial liver resection due to trauma, and 1 case had liver transplantation from corpse. RESULTS AND CONCLUSION:The survival time of the involve patients was 13-1 740 days, and the median survival time was 634 days. Perioperative survival rate was 76%, 1-year survival rate was 63%, and 2-year survival rate was 58%. During the perioperation nine cases died of brain edema and intracranial hypertension, renal failure, severe pulmonary infection, multiple organ failure, coagulation disorders (intracranial hemorrhage, upper digestive tract hemorrhage), acute respiratory distress syndrome and primary graft non-function. At present, emergency liver transplantation is stil the most effective way for acute liver failure. Hemorrhage, infection and rejection are the leading causes of the death. Each perioperative treatment is of great significance for the success of liver transplantation and long-term survival.%背景:急性肝衰竭行急诊肝移植患者围手术期治疗的病情复杂,风险大,并发症多,死亡率高,与普通肝脏移植有着明显不同。目的

    Dengue fever(DF) and dengue haemorrhagic fever(DHF) are important mosquito-borne viral diseases of humans and recognized as important emerging infectious diseases in the tropics and subtropics. Compared to nine reporting countries in the 1950s, today the geographic distribution includes more than100 countries worldwide. Dengue viral infections are known to present a diverse clinical spectrum, ranging from asymptomatic illness to fatal dengue shock syndrome. Mild hepatic dysfunction in dengue haemorrhagic fever is usual. However, its presentation as acute liver failure(ALF)is unusual. We report a patient with dengue shock syndrome who presented with acute liver failure and hepatic encephalopathy in a recent outbreak of dengue fever in Delhi, India.

    This study was conducted to analyse the course and the outcome of the liver disease in the co-infected animals in order to evaluate a possible synergic effect of human parvovirus B19 (B19V) and hepatitis A virus (HAV) co-infection. Nine adult cynomolgus monkeys were inoculated with serum obtained from a fatal case of B19V infection and/or a faecal suspension of acute HAV. The presence of specific antibodies to HAV and B19V, liver enzyme levels, viraemia, haematological changes, and necroinflammatory liver lesions were used for monitoring the infections. Seroconversion was confirmed in all infected groups. A similar pattern of B19V infection to human disease was observed, which was characterised by high and persistent viraemia in association with reticulocytopenia and mild to moderate anaemia during the period of investigation (59 days). Additionally, the intranuclear inclusion bodies were observed in pro-erythroblast cell from an infected cynomolgus and B19V Ag in hepatocytes. The erythroid hypoplasia and decrease in lymphocyte counts were more evident in the co-infected group. The present results demonstrated, for the first time, the susceptibility of cynomolgus to B19V infection, but it did not show a worsening of liver histopathology in the co-infected group.

    Liver infarction is relatively uncommon. It may be secondary to several conditions such as sepsis, shock, sickle-cell anaemia, eclampsia, vasculitis, metastatic disease, bacterial endocarditis, rheumatic heart disease, trauma, portal venous occlusion or compression, oral contraception, anaesthesia, hepatic artery thrombosis, therapeutical or inadvertent hepatic artery ligation, intra-arterial chemotherapy or embolisation. A case of hepatic infraction, unusual for iatrogenic pathogenesis, submassive extension with acute hepatic failure, and CT findings of an internally branching pattern due to intravascular gas was observed.

    Doxylamine succinate is an antihistaminic drugwith additional hypnotic, anticholinergic and local anesthetic effects first described in 1948. In Korea and many other countries, it is a common-over-the counter medication frequently involved in overdoses. Clinical symtomatology of doxylamine succinate overdose includes somnolence, coma, seizures, mydriasis, tachycardia, psychosis, and rhabdomyolysis. A serious complication may be rhabdomyolysis with subsequent impairment of renal function and acute renal failure. We report a case of acute renal failure and acute pancreatitis complicating a doxylamine succinate intoxication.

    of immunoglobulin M (IgM) anti-hepatitis B core antibody (anti-HBc) titers and of HBV viral loads (VLs) might allow the separation of AHBV-ALF from CHBV-ALF. Of 1,602 patients with ALF, 60 met clinical criteria for AHBV-ALF and 27 for CHBV-ALF. Sera were available on 47 and 23 patients, respectively. A quantitative...... immunoassay was used to determine IgM anti-HBc levels, and real-time polymerase chain reaction (rtPCR) was used to determine HBV VLs. AHBV-ALFs had much higher IgM anti-HBc titers than CHBV-ALFs (signal-to-noise [S/N] ratio median: 88.5; range, 0-1,120 versus 1.3, 0-750; P ...) of the AHBV-ALF group had no hepatitis B surface antigen (HBsAg) detectable on admission to study, wheras no CHBV-ALF patients experienced HBsAg clearance. Rates of transplant-free survival were 33% (20 of 60) for AHBV-ALF versus 11% (3 of 27) for CHBV-ALF (P = 0.030). CONCLUSIONS: AHBV-ALF and CHBV...

    AIM: To investigate the relationship between severe acute pancreatitis (SAP) and organ failure.METHODS: Clinical data of 74 cases of SAP from Jan. 1993 to Dec. 2002 were retrospectively reviewed, and the relationship between organ failure and age, gender, etiology,extent of necrosis, infection of necrosis and mortality was analyzed.RESULTS: A total of 47 patients (63.5 %) showed organ failure, 20 patients (27.0 %) multiple organ failure, whereas 27 patients (36.5 %) with dysfunction of a single organ system. Pulmonary failure was the most common organ dysfunction (23.0 %) among single organ failures. There were no significant differences in age, gender and gallstone pancreatitis among patients with or without organ failure (P>0.05). The incidence of organ failure in infected necrosis was not higher compared with sterile necrosis, and patients with increased amount of necrosis did not have an increased prevalence of organ failure (P>0.05). Patients with organ failure had a higher mortality rate compared with those without organ failure (P<0.05). The death of SAP was associated with multiple organ failure (P<0.005), pulmonary failure (P<0.005), cardiovascular dysfunction (P<0.05) and gastrointestinal dysfunction (P<0.05).CONCLUSION: Organ failure is common in patients with SAP, and patients with multiple organ failure and pulmonary failure have a higher mortality rate. Prevention and active treatment of organ failure can improve the outcome of patients with SAP.

    Brucellosis is a zoonotic infection that is transmitted from animals to humans by ingestion of infected food products, direct contact with an infected animal, or aerosol inhalation. The disease is endemic in many countries, including the Mediterranean basin, the Middle East, India, Mexico, Central and South America and, central and southwest Asia. Human brucellosis is a systemic infection with a wide clinical spectrum. Although hepatic involvement is very common during the course of chronic brucellosis, hepatic abscess is a very rare complication of Brucella infection. We present a case of hepatic abscess caused by Brucella, which resembled the clinical presentation of surgical acute abdomen.

    We report a patient with neuroleptic malignant syndrome (NMS) who developed acute renal failure and was successfully treated by hemodialysis. A 60-year-old man with a 26-year history of schizophrenia had been treated with thioridazine and sulpiride. He was admitted to our hospital for muscular rigidity and oliguria. After the diagnosis of NMS with acute renal failure was established, thioridazine and sulpiride were discontinued and hemodialysis was instituted. Renal function gradually improved and hemodialysis was discontinued after 17th treatment. We also reviewed 57 cases of NMS with acute renal failure reported in the literature. To our knowledge, 26 years is the longest latency between initiation of neuroleptic drug treatment and onset of NMS. Our review of reported NMS cases with acute renal failure identified those risks for poor prognosis as high level of BUN, age and female gender.

    There is scarce data pertaining to acute hepatitis C (aHC) infection in South America. We aimed to describe clinical characteristics and evolution of aHC in a South American cohort. A retrospective survey was conducted at 13 hepatology units. All patients ≥16 years old with aHC diagnosis were included. Demographic, clinical and outcome information were registered in a standardized ad hoc questionnaire. Sixty-four patients were included. The majority were middle-aged (median age: 46 years) and female (65.6%); most of them were symptomatic at diagnosis (79.6%). HCV-1 was the most prevalent genotype (69.2%). Five patients had liver failure: three cases of severe acute hepatitis, one case of fulminant hepatitis and one case of acute-on-chronic liver failure. Nosocomial exposure was the most prevalent risk factor. Evolution was assessed in 46 patients. In the untreated cohort, spontaneous resolution occurred in 45.8% and was associated with higher values of AST/ALT and with the absence of intermittent HCV RNA viremia (P = 0.01, 0.05, and 0.01, respectively). In the treated cohort, sustained virological response was associated with nosocomial transmission and early treatment initiation (P = 0.04 each). The prevalence of nosocomial transmission in this South-American cohort of aHC stresses the importance of following universal precautions to prevent HCV infection. J. Med.

    2007-01-01

    Study on the action mechanism of inflammatory mediators generated by the severe acute pancreatitis (SAP) in multiple organ injury is a hotspot in the surgical field. In clinical practice, the main complicated organ dysfunctions are shock, respiratory failure, renal failure, encephalopathy, with the rate of hepatic diseases being closely next to them. The hepatic injury caused by SAP cannot only aggravate the state of pancreatitis, but also develop into hepatic failure and cause patient death. Its complicated pathogenic mechanism is an obstacle in clinical treatment. Among many pathogenic factors, the changes ofvasoactive substances, participation of inflammatory mediators as well as OFR (oxygen free radical), endotoxin, etc. may play important roles in its progression.

  11. Fialuridine induces acute liver failure in chimeric TK-NOG mice: a model for detecting hepatic drug toxicity prior to human testing.

    Directory of Open Access Journals (Sweden)

    Dan Xu

    2014-04-01

    Full Text Available BACKGROUND: Seven of 15 clinical trial participants treated with a nucleoside analogue (fialuridine [FIAU] developed acute liver failure. Five treated participants died, and two required a liver transplant. Preclinical toxicology studies in mice, rats, dogs, and primates did not provide any indication that FIAU would be hepatotoxic in humans. Therefore, we investigated whether FIAU-induced liver toxicity could be detected in chimeric TK-NOG mice with humanized livers. METHODS AND FINDINGS: Control and chimeric TK-NOG mice with humanized livers were treated orally with FIAU 400, 100, 25, or 2.5 mg/kg/d. The response to drug treatment was evaluated by measuring plasma lactate and liver enzymes, by assessing liver histology, and by electron microscopy. After treatment with FIAU 400 mg/kg/d for 4 d, chimeric mice developed clinical and serologic evidence of liver failure and lactic acidosis. Analysis of liver tissue revealed steatosis in regions with human, but not mouse, hepatocytes. Electron micrographs revealed lipid and mitochondrial abnormalities in the human hepatocytes in FIAU-treated chimeric mice. Dose-dependent liver toxicity was detected in chimeric mice treated with FIAU 100, 25, or 2.5 mg/kg/d for 14 d. Liver toxicity did not develop in control mice that were treated with the same FIAU doses for 14 d. In contrast, treatment with another nucleotide analogue (sofosbuvir 440 or 44 mg/kg/d po for 14 d, which did not cause liver toxicity in human trial participants, did not cause liver toxicity in mice with humanized livers. CONCLUSIONS: FIAU-induced liver toxicity could be readily detected using chimeric TK-NOG mice with humanized livers, even when the mice were treated with a FIAU dose that was only 10-fold above the dose used in human participants. The clinical features, laboratory abnormalities, liver histology, and ultra-structural changes observed in FIAU-treated chimeric mice mirrored those of FIAU-treated human participants. The use

    Chronic liver disease is the fifth leading cause of death worldwide and represents a major burden for the health care community. Cirrhosis is a progressive disease resulting in end-stage liver failure, which in the absence of liver transplantation is fatal. Acute-on-chronic liver failure carries high short-term mortality but is potentially reversible. Viral hepatitis, alcohol, and nonalcoholic fatty liver disease remain the principal causes of liver disease. Though treatments exist for hepatitis B and C, they remain unavailable to many with these diseases. This article reviews the epidemiology of advanced liver disease and the concept of acute-on-chronic liver failure.

    The acute renal failure is the frequent medical complication observed in liver transplant patients. The objective of this study was to determine the cause of acute renal failure in post liver transplant patients. A total of 70 patients who underwent (cadaveric 52, live 18) liver transplantation were categorized based on clinical presentation into two groups, namely hepatorenal failure (HRF, n = 29), and Hepatic failure (HF, n = 41). All the patients after the liver transplant had received tacrolimus, mycophenolate and steroids. We analyzed the modification of diet in renal disease, (MDRD) serum urea, creatinine and albumin before and after 5th and 30th day of liver transplant and data was categorized into survivors and non-survivors group. In HRF survivor group, serum creatinine, and urea levels were high and, albumin, MDRD were low in pre- transplant and reached to normal levels on 30th day of post transplant, and 79.3 % of patients in this group showed resumption of normal kidney function. On the contrary in HRF nonsurvivor group, we did not observed any significant difference and 20.7 % of patients showed irreversible changes after the liver transplant. In HF survivor group, 82.9 % of liver failure patients did not show any deviation in serum creatinine, urea, albumin and MDRD, whereas in HF non survivor group, 17.1 % of liver failure patients who had HCV positive before the transplant developed acute renal failure. The levels of creatinine, urea, albumin and MDRD were normal before the transplant and on day 30th, the levels of albumin and MDRD were significantly low whereas serum urea, creatinine levels were high. In conclusion, based on these observations, an diagnosis and treatment of Acute renal failure is important among the liver transplantation cases in the early postoperative period.

    Human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells have an enormous potential; however, their potential clinical application is being arrested due to various limitations such as teratoma formation followed by tumorigenesis, emergent usage, and the quality control of cells, as well as safety issues regarding long-term culture are also delaying their clinical application. In addition, human ES cells have two crucial issues: immunogenicity and ethical issues associated with their clinical application. The efficient generation of human iPS cells requires gene transfer, yet the mechanism underlying pluripotent stem cell induction has not yet been fully elucidated. Otherwise, although human adult regenerative cells including mesenchymal stem cells have a limited capacity for differentiation, they are nevertheless promising candidates for tissue regeneration in a clinical setting. This review highlights the use of regenerative cells for transplantation in hepatic failure.

    2016-09-01

    Primary systemic amyloidosis is a rare disorder resulting in extracellular deposition of insoluble fibrils in different organs. Liver involvement has been reported. Since hepatic amyloidosis often presents clinically asymptomatic without specific laboratory or imaging hallmarks, diagnosis is challenging. However, cases of progressive hepatic failure due to liver amyloidosis have been reported. A 63 year old man presented with newly diagnosed ascites to our department. The patient reported occasional alcohol consumption. Viral hepatitis, genetic-metabolic causes as well as hepatic vascular disorders were excluded and ultrasound did not show any signs of liver cirrhosis or intraabdominal malignancy. Initially, alcoholic hepatitis was suspected. Due to the rapid deterioration of liver function, however, transjugular liver biopsy was performed showing light chain amyloidosis of kappa isotype. As diagnosis of hepatic amyloidosis is challenging, early liver biopsy is mandatory in patients with unexplained acute or chronic liver disease to exclude rare diseases with high mortality.

    A 20-year-old woman was admitted to an emergency hospital after ingesting 66 g of acetylsalicylic acid in a suicide attempt. Although she was treated with gastric lavage, oral activated charcoal, and intravenous hydration with sodium bicarbonate, her hepatic and renal function gradually deteriorated and serum amylase levels increased. Steroid pulse therapy, plasma exchange, and continuous hemodiafiltration did not yield any improvement in her hepatic or renal function, and she was transferred to our hospital for living donor liver transplantation. Nine days after drug ingestion, she developed hepatic encephalopathy: thus, we diagnosed the patient with acute liver failure with hepatic coma accompanied by acute pancreatitis due to the overdose of acetylsalicylic acid. Living donor liver transplantation was immediately performed using a left lobe graft from the patient's mother. Following transplantation, the patient's renal and hepatic function and consciousness improved, and she was discharged. In this report, we describe a rare case of acetylsalicylic acid-induced acute liver failure with acute hepatic coma and concomitant acute pancreatitis and acute renal failure, which were treated successfully with emergency living donor liver transplantation.

    2015-01-01

    Fulminant hepatic failure is liver disease that causes encephalopathy within 8 weeks of onset of symptoms or within 2 weeks of onset of jaundice in a patient without prior evidence of liver disease. Autoimmune polyendocrine syndrome type-1 is an autoimmune autosomal-recessive condition causing parathyroid and adrenal insufficiency, alopecia, chronic mucocutaneous candidiasis, ectodermal dystrophy and, rarely, hepatitis. Although the liver can be affected as a consequence of the autoimmune process, the spectrum of disease activity is varied. Autoimmune hepatitis develops in 10-20% of patients and successful liver transplantation has been reported in pediatric patients who failed immunosuppressive treatment. We report fulminant hepatic failure in an adult patient with autoimmune polyendocrine syndrome type-1 who responded to medical treatment and did not require liver transplantation. We highlight the diagnostic scoring system for autoimmune hepatitis and the referral criteria for liver transplantation in fulminant hepatic failure.

    Full Text Available Hymenoptera is a class of insects that sting in order to subdue their prey. Humans coming into accidental contact with these insects results in stings that may cause from mild local reaction like weal formation around the sting site to severe systemic reactions such as intravascular hemolysis, acute renal failure, pulmonary edema, cerebral edema, and rarely pancreatitis. We report here the clinical course of a patient who developed concurrent acute pancreatitis and pigment-induced acute renal failure after multiple hornet stings.

    When a patient with acetaminophen overdose arrives in the emergency room more than 14 hours after ingestion, the value of N-acetylcysteine is unproven and patient mortality is at least 10%. Anecdotal case reports have indicated benefit of extracorporeal detoxification of these late-arriving patients with acetaminophen overdose. We identified 10 patients with serious acetaminophen overdose, 8 that arrived in the emergency room 16 to 44 hours after acetaminophen overdose with plasma levels predicting severe hepatic toxicity, and 2 that arrived in the emergency room 8 to 12 hours after overdose but with exceedingly high levels. All patients developed severe hepatitis (mean peak alanine aminotransferase, 4,052; mean peak protime, 25 seconds). At 16 to 68 hours after overdose, the patients were treated for 4 to 6 hours with the Liver Dialysis System (Hemocleanse Inc, W. Lafayette, IN), a single-access hemodiabsorption system indicated for treatment of serious drug overdose and for treatment of hepatic encephalopathy. Acetaminophen levels fell an average of 73% during treatment. Treatment was repeated 24 or 48 hours later if acetaminophen was still measurable in plasma. All 10 patients recovered intrinsic liver function and general health, with liver enzymes starting to normalize 24 hours after treatment, and were discharged 3 to 7 days after overdose. No patient required liver transplant. Because market introduction of Liver Dialysis, there have been 40 more patients with acetaminophen-induced hepatotoxicity treated with Liver Dialysis. All have recovered liver function without long-term sequelae. Though most of these patients with already established hepatic toxicity from acetaminophen would recover without extracorporeal blood therapy, treatment with the Liver Dialysis System should assure recovery from acute hepatic failure, and may shorten the clinical course of the illness.

    Full Text Available Introduction Brucellosis is a common zoonotic disease which has a wide spectrum of clinical manifestations and complications in humans. Brucellosis is an endemic disease in Iran. The aim of this case report was to introduce acute hepatitis as a rare complication of acute brucellosis. Case Presentation First case, a 25-year-old man, who complained from fever, chillness, nocturnal sweating, nausea, vomiting, jaundice, and right upper quadrant pain, and was admitted to the hospital. Laboratory tests showed a five-fold increase in alanine aminotransferase and aspartate aminotransferase levels, and increased total and direct bilirubin and alkaline phosphatase levels. Second case, a 63-year-old man, who complained from fever, chillness, weight loss, malaise and nocturnal sweating, and was admitted to the hospital. Laboratory tests showed an eight-fold increase in alanine aminotransferase and aspartate aminotransferase levels, and increased total and direct bilirubin and alkaline phosphatase levels. The patient had jaundice at the third day of admission. The results of seroagglutination tests, Wright and 2-mercaptoethanol (2ME were positive for both patients. The patients were diagnosed as having acute brucella hepatitis and were treated with standard regimen of anti-brucella drugs and improved completely after six weeks of treatment. Conclusions Brucellosis must be considered in the differential diagnosis of acute hepatitis in patients with jaundice and fever manifestations especially if there is a history of unpasteurized dairy products ingestion and life in endemic areas because early diagnosis and treatment of the patient can decrease complications and mortality rate.

    Hepatitis C virus (HCV) infection is frequent in patients with end-stage renal disease treated by chronic dialysis, with a prevalence varying from 10-65% according to the geographical data. The prevalence is significantly associated with the duration of dialysis and the number of transfused blood products[1,2] and has dramatically declined with efficient blood screening.[3] We studied patients with acute HCV infection in a dialysis unit. The diagnosis was based on both anti-HCV detection and HCV-RNA detection. Other virological tools including HCV genotype determination was also used to tailor treatment to the individual patient and determine its efficacy for a one-year follow-up period. Seventeen patients (7 male and 10 female, mean age: 63.7 +/- 11.6 SD) with acute hepatitis C were enrolled to our study. All of them were followed up for a period of one year after the diagnosis was established. Phylogenetic analysis distinguished two separate HCV subtypes 1b, which were both responsible for this acute infection (see Figure 1). These types did not differ in their behavior on the clinical situation of our patients, as confirmed by the fact that in both groups of patients, there was only one patient who presented with acute illness. Six patients of our study group, three months after the acute infection, received pegylated interferon (Peg-IFNa2a) 135 mug for a six-month period. Four of them responded very well to therapy and at the first determination HCV RNA was below the cutoff point. One of our patients with very high HCV levels (HCV RNA > 50,000,000 IU/mL), despite receiving the same therapy, did not respond well and developed cirrhosis. In conclusion, it is clear from our experience that better information is needed about the current incidence, prevalence, and risk factors for HCV infection in dialysis patients. Algorithms for the diagnosis and management of hepatitis C should be developed by academic societies. Routine screening for hepatitis C also would allow

    Hepatitis E infection is an important cause of fulminant hepatic failure (FHF) in pregnancy in developing countries like India, with a high mortality rate. It is postulated that immunological and hormonal changes in pregnant women predispose them to developing FHF secondary to hepatitis E infection as compared to the less severe form seen in the non-pregnant population. A variation in the natural course of the disease is also seen amongst different geographical areas. Hepatitis E infection is...

    Alverine citrate is a commonly used smooth muscle relaxant agent. A MEDLINE search on January 2004 revealed only 1 report implicating the hepatotoxicity of this agent. A 34-year-old woman was investigated because of the finding of elevated liver function tests on biochemical screening. Other etiologies of hepatitis were appropriately ruled out and elevated enzymes were ascribed to alverine citrate treatment.Although alverine citrate hepatotoxicity was related to an immune mechanism in the first case, several features such as absence of predictable dose-dependent toxicity of alverine citrate in a previous study and absence of hypersensitivity manifestations in our patient are suggestive of a metabolic type of idiosyncratic toxicity.

    Full Text Available Arantxa Mas, Josep MasipCritical Care Department, Consorci Sanitari Integral (CSI, Hospital Sant Joan Despí Moisès Broggi and Hospital General de l’Hospitalet, University of Barcelona, Barcelona, SpainAbstract: After the institution of positive-pressure ventilation, the use of noninvasive ventilation (NIV through an interface substantially increased. The first technique was continuous positive airway pressure; but, after the introduction of pressure support ventilation at the end of the 20th century, this became the main modality. Both techniques, and some others that have been recently introduced and which integrate some technological innovations, have extensively demonstrated a faster improvement of acute respiratory failure in different patient populations, avoiding endotracheal intubation and facilitating the release of conventional invasive mechanical ventilation. In acute settings, NIV is currently the first-line treatment for moderate-to-severe chronic obstructive pulmonary disease exacerbation as well as for acute cardiogenic pulmonary edema and should be considered in immunocompromised patients with acute respiratory insufficiency, in difficult weaning, and in the prevention of postextubation failure. Alternatively, it can also be used in the postoperative period and in cases of pneumonia and asthma or as a palliative treatment. NIV is currently used in a wide range of acute settings, such as critical care and emergency departments, hospital wards, palliative or pediatric units, and in pre-hospital care. It is also used as a home care therapy in patients with chronic pulmonary or sleep disorders. The appropriate selection of patients and the adaptation to the technique are the keys to success. This review essentially analyzes the evidence of benefits of NIV in different populations with acute respiratory failure and describes the main modalities, new devices, and some practical aspects of the use of this technique.

    A transient reduction of hepatitis C virus replication during the course of acute hepatitis A virus infection has already been reported in the literature. The present study reports the case study of a subject with chronic hepatitis due to hepatitis C virus who went on to develop an acute hepatitis A. From the early onset of acute disease, hepatitis C virus ribonucleic acid became undetectable. Following recovery from acute hepatitis, alanine amino-transferase levels became persistently normal and liver biopsy revealed a reduction in the Knodell histological activity index score. Hepatitis C virus ribonucleic acid clearance was maintained up to 4 years after the onset of acute hepatitis A. During the course of the acute disease, a sharp increase in interferon gamma levels was detected in serum and in the supernatant of both unstimulated and phytoemagglutinin/lipopolysaccharide-stimulated peripheral blood mononuclear cells. Interferon gamma levels were still high 3 months later. We hypothesize that acute hepatitis A virus superinfection during the course of chronic hepatitis C may lead to hepatitis C virus ribonucleic acid clearance through an immunological mechanism related to interferon gamma production.

    Objective:To establish the animal model of hepatocyte transplantation via hepatic artery in SD rats;to evaluate the treatment effects of hepatocyte transplantation by hepatic artery and intrasplenic injection in rats with acute hepatic failure. Methods :A-cute hepatic failure(AHF) was induced by D-gal in SD rats. After 24 hours,a cather was inserted into the hepatic artery in 65 rats with AHF. Then the 60 rats were randomly divided into 3 groups. Group Ⅰ received 2×107 hepatocytes through intraplenic injection and 0.4 ml Hank's solution was infused through hepatic artery;Group Ⅱ received 0.4 ml Hank's solution through intraplenic injection and 2×107 hepatocytes was infused through hepatic artery;Group Ⅲ received 0.4 ml Hank's solution through intraplenic injection and 0.4 ml Hank's solution through hepatic artery .Surviving rate was observed at 14 days and liver function was measured at different time points. The distribution of transplanted CFDA-SE-labeled hepatocytes through hepatic artery was observed.Secretion of albumin and liver histopathological change were observed in spleen by immunofluorescence and HE staining. Results:Al 14 days,the survival of Group Ⅰ rats was significantly higher than that of Group Ⅱ rats (P=0.031 ,<0.05); the survival of Group Ⅱ was significantly higher than that of Group Ⅲ (P=0.048,<0.05).Hepatic function of Groups Ⅰ and Ⅱ had improved,especially of Group Ⅰ . In Group Ⅱ ,24 h after transplantation of CFDA-SE-labeled hepatocytes,scattered green fluorescence region was found under fluorescent microscopy. In Group Ⅰ ,at 30 days post-lransplatation,immflnofluorescent staining of albumin demonstrated some positive cells in spleen;at 7 days post-transplatation,transplanted hepatocytes was found in spleen. Conclusion:Hepatocyte transplantation through catheteriza-tion hepatic artery via carotid route can improve the survival of rats with AHF and ameliorate hepatic function,but intrasplenic injection is

  12. Clindamycin-induced acute cholestatic hepatitis

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    We report a case of acute hepatotoxicity in a 42-yearold woman after administration of clindamycin for a dental infection. After 6 d of treatment, she had fatigue, nausea, vomiting, anorexia, pruritus and jaundice. Her laboratory analysis showed alanine aminotransferase (ALT), 1795 IU/L (normal range 0-40); aspartate aminotransferase (AST), 1337 IU/L (normal range 5-34); alkaline phosphatase (ALP), 339 IU/L (normal range 40-150); γ-glutamyl transpeptidase (GGT), 148 IU/L (normal range 9-64 IU/L); total bilirubin, 4.1 mg/dL; direct bilirubin, 2.9 mg/dL and prothrombin time (PT), 13.5 s, with international normalized ratio (INR), 1.04. She was hospitalized, with immediate drug discontinuation. Her liver biopsy specimen showed mixed-type (both hepatocellular and cholestatic) hepatic injury, compatible with a diagnosis of drug-induced hepatitis. An objective causality assessment using the Naranjo probability scale suggested that clindamycin was the probable cause of the acute hepatitis. In susceptible individuals, clindamycin use may lead to acute mixedtype liver toxicity. Complete recovery may be possible if the drug is discontinued before severe liver injury is established.

    Full Text Available Respiratory failure is a serious complication of scrub typhus. In this prospective study, all patients with a diagnosis of scrub typhus were included from a single center Intensive Care Unit (ICU. Demographic, clinical characteristics, laboratory, and imaging parameters of these patients at the time of ICU admission were compared. Of the 55 scrub typhus patients, 27 (49% had an acute respiratory failure. Seventeen patients had acute respiratory distress syndrome, and ten had cardiogenic pulmonary edema. Respiratory supported patients were older had significant chronic lungs disease and high severity illness scores (Acute Physiology and Chronic Health Evaluation-II and Sequential Organ Failure Assessment score. At ICU admission, these patients presented with more deranged laboratory markers, including high bilirubin, high creatine kinase, high lactate, metabolic acidosis, low serum albumin, and presence of ascites. The average ICU and hospital stay were 4.27 ± 2.74 and 6.53 ± 3.52 days, respectively, in the respiratory supported group. Three patients died in respiratory failure group, while only one patient died in nonrespiratory failure group.

    1984-02-01

    Ninety-three cases of acute viral hepatitis in adult Lebanese patients were followed-up prospectively for a period ranging from 6 to 18 months. These included 33 hepatitis A (HAV), 32 hepatitis B (HBV) and 21 non-A, non-B hepatitis (NANB) cases. The clinical and seroepidemiologic characteristics of the three types were evaluated. HAV was characterized by a short prodroma (less than 1 week) and a high IgM level. HBV did not differ from similar cases reported in the Western world except for a complete absence of male homosexuals and drug addicts as a possible route of transmission. NANB hepatitis in Lebanon is mainly a sporadic infection similar to HAV except that the prodromal phase is prolonged (greater than 14 days) and IgM levels are within normal limits. The failure to develop chronicity in NANB suggests that the virus of sporadic NANB may be different from that which causes post-transfusional (PTH) NANB.

    Full Text Available Brucella infection is a systemic disease. It rarely causes local infections like hepatitis in gastrointestinal system. In this article we would like to present an acute hepatitis case related to brucella infection that followed up in our clinic. A male, 30 year-old patient hospitalized due to common muscle pain, high fever and vomiting. During the physical examination the patient’s skin, scleras and mucosal membranes were icteric, the liver was 2-3 cm palpable and tender. Laboratory findings were as follows: AST:1190 U/L; ALT:715 U/L; GGT:961 U/L; ALP:369 U/L; total bilirubin:4.6 mg/dL; direct bilirubin:2.1 mg/dL. Viral markers were found to be negative. We started treatment with streptomicine and doxicycline since, the patient’s standard brucella tube agglutination test was positive (1/60 and brucella spp produced in his blood culture. From the second day of the treatment, we started to get clinical response. On the 17th day of the treatment, he discharged from the hospital because ALT, AST and bilirubine level were found normal and his treatment was completed to the 8 weeks. Brucella is continuing to be an important health problem especially who live in surrounding countryside and have to keep in mind in the differential diagnosis of the acute hepatitis.

    Moore, Joanna K; Love, Eleanor; Craig, Darren G; Hayes, Peter C; Simpson, Kenneth J

    2013-11-01

    Acute liver failure is a rare and often devastating condition consequent on massive liver cell necrosis that frequently affects young, previously healthy individuals resulting in altered cognitive function, coagulopathy and peripheral vasodilation. These patients frequently develop concurrent acute kidney injury (AKI). This abrupt and sustained decline in renal function, through a number of pathogenic mechanisms such as renal hypoperfusion, direct drug-induced nephrotoxicity or sepsis/systemic inflammatory response contributes to increased morbidity and is strongly associated with a worse prognosis. Improved understanding of the pathophysiology AKI in the context of acute liver failure may be beneficial in a number of areas; the development of new and sensitive biomarkers of renal dysfunction, refining prognosis and organ allocation, and ultimately leading to the development of novel treatment strategies, these issues are discussed in more detail in this expert review.

    2012-01-01

    Full Text Available Background: Hepatitis E is being increasingly recognized as an emerging infection in developed countries. Data on histological findings and nature of inflammatory cell infiltrate in liver in this disease are quite sparse. Aims: This study was planned to study the histological features and the type of inflammatory infiltrate in liver biopsies of patients with acute fulminant hepatitis E. Materials and Methods: We retrieved postmortem liver biopsies of 11 Indian patients with fulminant hepatitis E, and compared these with biopsies from seven patients with fulminant hepatitis B. Results : Biopsies from acute fulminant hepatitis E showed varying degrees of hepatocyte necrosis, mixed portal and lobular inflammation, accompanied by bile ductular proliferation, lymphocytic cholangitis, Kupffer cell prominence, cholestasis, apoptotic bodies, pseudo-rosette formation, steatosis, and presence of plasma cells in portal tracts. Interface hepatitis was more frequent in acute hepatitis B than in acute hepatitis E (100% vs 20%; P<0.05. These findings differ from those reported in cases with autochthonous hepatitis E in Europe. On immunohistochemistry, lymphocyte infiltrate consisted predominantly of CD3 + T cells in both hepatitis E and hepatitis B; these cells contained a predominant cytotoxic (CD8 + cell subpopulation in 81.8% of cases with hepatitis E and in 50% of cases with hepatitis B. Conclusion: Our findings suggest that histological changes in HEV infection may vary with geographical location because of prevalent HEV genotypes, and that CD8 + lymphocytes play a role in HEV-induced liver injury.

    Full Text Available Background and Aim. Levetiracetam is a second-generation antiepileptic drug. It is approved as an adjunctive treatment of partial onset seizures with or without secondary generalization. It is considered safe with less than 1% of patients with transient elevations of liver enzymes. Methods. We report a case of acute liver failure secondary to Levetiracetam in combination with Lacosamide documented with a liver biopsy. Results. Liver biopsy demonstrated acute liver injury with a predominant submassive necrosis pattern and features of a drug-induced hepatitis. Conclusions. This is the first published case of acute liver failure due to antiepileptic therapy with Levetiracetam in combination with Lacosamide.

  6. [Acute heart failure: acute cardiogenic pulmonary edema and cardiogenic shock].

    Science.gov (United States)

    Sánchez Marteles, Marta; Urrutia, Agustín

    2014-03-01

    Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. Correct evaluation and clinical identification of the process is essential in the management of acute pulmonary edema. The initial aim of treatment is to ensure hemodynamic stability and to correct hypoxemia. Other measures that can be used are vasodilators such as nitroglycerin, loop diuretics and, in specific instances, opioids. Cardiogenic shock is characterized by sustained hypoperfusion, pulmonary wedge pressure > 18 mmHg and a cardiac index 30 mmHg) and absent or reduced diuresis (< 0.5 ml/kg/h). The most common cause is left ventricular failure due to acute myocardial infarction. Treatment consists of general measures to reverse acidosis and hypoxemia, as well as the use of vasopressors and inotropic drugs. Early coronary revascularization has been demonstrated to improve survival in shock associated with ischaemic heart disease.

    Acute renal failure (ARF) in a neonate is a serious condition that impacts 8% to 24% of hospitalized neonates. There is a need for prompt evaluation and treatment to avoid additional complications. In this review, a neonate was found to have renal failure associated with renal vein thrombosis. There are varying etiologies of ARF. Causes of ARF are typically divided into three subsets: pre-renal, renal or intrinsic, and post-renal. Treatment of ARF varies based on the cause. Renal vein thrombosis is an interesting cause of renal or intrinsic ARF and can be serious, often leading to a need for dialysis.

    2011-09-01

    Full Text Available Bladder rupture is a rare condition associated with significant morbidityand mortality. It is classified into traumatic, nontraumatic or idiopathic andspontaneous. The nonspecific initial clinical presentation is followed bydiscomfort in the lower abdomen, oliguria, hematuria and ascitis. Laboratoryabnormalities simulate the picture of acute renal failure and occurs by amechanism called auto reverse dialysis, with absorption of excreta throughthe peritoneal membrane. The authors describe a case of bladder rupturein morphologically and functionally normal urinary bladder associated withalcohol intake in young healthy man, manifested by abdominal discomfort,pseudo renal failure and massive ascitis. The diagnosis was made by anabdominal multidetector computed tomography confirmed by the finding of7 cm laceration at laparotomy.

    2014-07-01

    Cardiogenic shock remains a leading cause of mortality despite advances in the treatment of myocardial infarction and advanced heart failure. Medical therapy can be inadequate, and patients may need mechanical circulatory support (MCS). The proper application of MCS requires knowledge of the underlying cause of acute heart failure, familiarity with the circulatory support devices, and the potential benefits and limitations of device therapy. This article describes the most commonly used temporary ventricular assist devices and their use in the various causes of cardiogenic shock.

  11. Acute Brucella Hepatitis in an Urban Patient

    Directory of Open Access Journals (Sweden)

    Seyed Moayed Alavian

    2009-11-01

    Full Text Available A 35-year-old man was referred to our center because of low grade fever, vomiting, yellow sclera, and tenderness in the upper-right quadrant of his abdomen. Laboratory tests showed a white blood cell (WBC of 7100/µL, a platelet of 184,000/µL, an erythrocyte sedimentation rate (ESR of 4 mm/h, an alanine aminotransferase (ALT of 525 U/L, an aspartate aminotransferase AST of 142 U/L, a total bilirubin level of 4.23 mg/dL, and a direct bilirubin level of 3.16 mg/dL. Viral hepatitis markers, immunoglobuline M antibody to cytomegalovirus (anti-CMV IgM, Ebstein-Barr virus (EBV IgM, and immunologic markers of autoimmune hepatitis were negative. The patient was diagnosed with acute hepatitis. Alkaline phosphatase was in the normal range throughout the course of the disease. Because of the patient's occupation as a butcher and his history of eating semi-cooked sheep testes, serologic tests of brucellosis were conducted; the tests came out positive. We were concerned about the hepatotoxicity of standard regimens; therefore, we started treatment with streptomycin and ciprofloxacin regimens. Although liver enzyme had fallen and fever discontinued, the total and direct bilirubin concentrations in the patient's serum both increased in spite of using 2 weeks of the abovementioned drug regimen. The elevation of bilirubin could have been due to drug hepatotoxicity. Alternatively, a regimen containing ciprofloxacin may have not have been efficient enough and may have had effects on the direct bilirubin concentration. Fortunately, within 8 weeks, progressive recovery was noticed. Brucellosis should be considered in the differential diagnosis of fever and hepatitis for those who live in endemic areas, especially if his/her job was at high risk for acquiring brucellosis. We recommend taking a careful occupational and behavioral history for patients with acute hepatitis syndrome. We assumed that ciprofloxacin was not suitable for brucella hepatitis treatment and

    This study aimed to identify acute self-limited hepatitis B (ASL-HB) among patients presenting with hepatitis B virus (HBV)-related acute hepatitis. Data were available for 220 patients diagnosed with HBV-related acute hepatitis, of whom 164 had acute hepatitis B (AHB). Of these, 160 were confirmed as ASL-HB: three (1.9%) evolved to chronic hepatitis B and one (0.6%) developed fulminant hepatitis and died. Comparisons were also made between AHB and acute infections with hepatitis A (HA) and hepatitis E (HE) viruses. During the study period, the number of patients with AHB exceeded the sum of those with acute HA and acute HE infections. There was no distinct seasonal peak for AHB infection, whereas both acute HA and acute HE infections occurred more frequently in the spring. Clinical symptoms and physical signs were similar for all three types of hepatitis, but significant differences were seen in some biochemical parameters. In conclusion, this study suggests that symptomatic AHB is not rare in China but it seldom evolves to chronic hepatitis B.

    The neuroleptic malignant syndrome is characterized by hyperpyrexia, muscle rigidity, extrapyramidal motion disorder, vegetative symptoms and mental disorientation. This group of symptoms develops abruptly and may lead to serious complications. One of these complications is the acute renal failure. Permanent muscle rigidity causes the damage of muscle cells which result in myoglobinaemia, myoglobinuria and elevations in muscle related creatine phosphokinase. The authors report the case of a young man who underwent neuroleptic medication because of hebephrenia. During the medication the following symptoms were developed: extrapyramidal symptoms, restlessness, muscle rigidity, high fever. These symptoms eventually lead to acute renal failure caused by rhabdomyolysis (characteristic urine finding, significant elevations in serum creatine phosphokinase). With regards to the neuroleptic malignant syndrome dantrolenum and bromocriptin treatment were applied with the discontinuation of neuroleptic medication. As a part of the complex therapy a massive volumen-supplementing and alkalizing treatment was used but haemodialysis had also become necessary. During the above mentioned treatment symptoms referring to the neuroleptic malignant syndrome resolved and the acute renal failure was cured. The case report calls attention to a specific group of symptoms and the possibilities for prevention and treatment. The above case report is the first observation in Hungary.

    The purpose of this study was to report the CT findings of four patients with hepatic abscess secondary to perforated acute cholecystitis. We retrospectively reviewed the CT findings of four patients with surgically proven hepatic abscess secondary to perforated acute cholecystitis. CT findings were analysed with respect to the observation of the gallbladder, pericholecystic space, hepatic lesions, and peritoneal cavity. All patients underwent cholecystectomy, with drainage of the hepatic abscess. CT findings of hepatic abscess secondary to perforated acute cholecystitis were hypodense mass formation in the pericholecystic space(n=3), irreguarity and wall defect of Gallbladder(n=4), thickened Gallbladder wall(n=4), stone with debris(n=4), and local or diffuse infiltration of the pericholecystic area(n=3), omentum, and mesentery. CT was helpful in diagnosing the hepatic abscess secondary to perforated acute cholecystitis.

    Heart failure may lead to subclinical circulatory disturbances and remain an unrecognized cause of ischemic liver injury. We present the case of a previously healthy 40-year-old bodybuilder, referred to our Intensive-Care Unit of Hepatology for treatment of severe acute liver failure, with the suspicion of toxic hepatitis associated with anabolic steroid abuse. Despite the absence of symptoms and signs of congestive heart failure at admission, an anabolic steroid-induced dilated cardiomyopathy with a large thrombus in both ventricles was found to be the underlying cause of the liver injury. Treatment for the initially unrecognized heart failure rapidly restored liver function to normal. To our knowledge, this is the first reported case of severe acute liver failure due to an unrecognized anabolic steroid-induced cardiomyopathy. Awareness of this unique presentation will allow for prompt treatment of this potentially fatal cause of liver failure.

    Full Text Available Acute renal failure (ARF is defined as a rapid decrease in the glomerular filtration rate, occurring over a period of hours to days. The Science and Technology University Hospital, Sana′a, is a referral hospital that caters to patients from all parts of Yemen. The aim of this study is to have a deeper overview about the epidemiological status of ARF in Yemeni patients and to identify the major causes of ARF in this country. We studied 203 patients with ARF over a period of 24 months. We found that tropical infectious diseases constituted the major causes of ARF, seen in 45.3% of the patients. Malaria was the most important and dominant infectious disease causing ARF. Hypotension secondary to infection or cardiac failure was seen in 28.6% of the patients. Obstructive nephropathy due to urolithiasis or prostate enlargement was the cause of ARF in a small number of patients. ARF was a part of multi-organ failure in 19.7% of the patients, and was accompanied by a high mortality rate. Majority of the patients were managed conservatively, and only 39.9% required dialysis. Our study suggests that early detection of renal failure helps improve the outcome and return of renal function to normal. Mortality was high in patients with malaria and in those with associated hepatocellular failure.

    Patients with cirrhosis are vulnerable to acute hepatic insults and are more likely to develop rapid hepatic deterioration. The aim of this study is to describe the clinical course of patients with cirrhosis and hospitalized for acute hepatic deterioration (AHD).This is a prospective study involving 163 patients with cirrhosis and AHD. The occurrence of organ failures, systemic inflammatory response syndrome (SIRS), and infections during hospital stay were recorded and the relationship between organ failure and death or SIRS/infection was subsequently analyzed.Of 163 patients, 35 did not develop any organ failure during in-hospital follow-ups (90-day mortality: 0%); 84 had intrahepatic organ failures (IH-OFs, defined by liver and/or coagulation failure) (90-day mortality: 22.0%); and 44 patients developed extra-hepatic organ failures (EH-OFs, defined by kidney, cerebral, circulation, and respiratory failure) on the basis of IH-OF with a 90-day mortality of 90.9%. On multivariable analysis by a Cox proportion hazard model, age, WBC, presence of IH-OF, and EH-OF all predicted 90-day death. A logistic regression analysis identified SIRS being associated with the development of EH-OF. Furthermore, IH-OF at admission and infections occurred during the hospital stay were shown to be another 2 potential risk factors.The clinical course of cirrhosis patients with acute hepatic injury was characterized by 3 consecutive stages (AHD, IH-OF, and EH-OF), which provided a clear risk stratification. The PIRO criteria provided an accurate frame for prognostication of those patients. The systemic inflammatory response syndrome may be a target for blocking the progression to the EH-OF stage.

    Maiwall, Rakhi; Sarin, S K; Moreau, Richard

    2016-03-01

    Acute on chronic liver failure (ACLF) is a distinct clinical entity; however, there is still debate in the way it is defined in the East as compared to the West, especially with respect to incorporation of kidney dysfunction or failure in the definition of ACLF. Kidney dysfunction is defined as serum creatinine between 1.5 and 1.9 mg/dl and kidney failure as serum creatinine of more than 2 mg/dl or requirement of renal replacement therapy according to the EASL-CLIF Consortium. Kidney dysfunction or failure is universally present in patients with ACLF according to the definition by the EASL-CLIF Consortium while on the contrary the APASL definition of ACLF does not incorporate kidney dysfunction or failure in its definition. Recently, both the diagnosis and management of renal failure in patients with cirrhosis has changed with the advent of the acute kidney injury (AKI) criteria defined as an abrupt decline in renal functions, characterized by an absolute increase in serum creatinine of 0.3 mg/dl within 48 h or an increase of more than 50 % from baseline, which is known or presumed to have occurred in the previous 7 days. Further, recent studies in patients with cirrhosis have shown the utility of biomarkers for the diagnosis of AKI. The present review covers the pathogenetic mechanisms, diagnosis, prognosis as well as management of AKI in patients with ACLF from both a Western as well as an Eastern perspective. The review identifies an unmet need to diagnose AKI and prevent this ominous complication in patients with ACLF.

    The availability of adequate experimental models of acute liver failure (ALF) is of prime importance to provide a better understanding of this condition and allow the development and testing of new therapeutic approaches for patients with ALF. However, the numerous etiologies and complications of ALF contribute to the complexity of this condition and render the development of an ideal experimental model of ALF more difficult than expected. Instead, a number of different models that may be used for the study of specific aspects of ALF have been developed. The most common approaches used to induce ALFin experimental animals are surgical procedures, toxic liver injury,or a combination of both. Despite the high prevalence of viral hepatitis worldwide, very few satisfactory viral models of ALF are available. Established and newly developed models of ALF are reviewed.

    Full Text Available Acute nontraumatic exertional rhabdomyolysis may arise when the energy supply to muscle is insufficient to meet demands, particularly in physically untrained individuals. We report on a psychiatric patient who developed large bruises and hemorrhagic blisters on both hands and arms, rhabdomyolysis of both forearm muscles with a moderate compartment syndrome, and consecutive acute renal failure following excessive work in the garden. Although specifically asked, the patient denied any hard physical work or gardening, and heteroanamnestic data were not available. The diagnosis of rhabdomyolysis was easy to establish, but until reliable anamnestic data were obtained, the etiology remained uncertain. Four days after arrival, the patient recalled working hard in the garden. The etiology of rhabdomyolysis was finally reached, and the importance of anamnestic data was once more confirmed.

    Directory of Open Access Journals (Sweden)

    Nieto-Ríos, John Fredy

    2016-04-01

    Full Text Available Acute renal failure is a frequent cause of morbidity and mortality in emergency, hospitalization and critical care services. In 15 % of cases it is due to rhabdomyolysis, in which there is breakdown of skeletal muscle with massive necrosis and leakage of muscle cell contents into the circulation. It has many different etiologies. The rhabdomyolysis-induced acute kidney injury results from the combination of several mechanisms, including tubular obstruction, vasoconstriction and oxidative stress. The most important therapeutic measures are: Aggressive repletion of fluids, forced diuresis and avoidance of exposure to nephrotoxic substances. In cases of severe uremia, metabolic acidosis, hiperkalemia or fluid overload it is necessary to start renal replacement therapy. As a rule, kidney function is completely recovered, but these patients have higher risk of future chronic kidney disease.

    Managing patients with heart failure (HF) is a challenging task within itself, but the presence of associated worsening renal function can greatly increase mortality and morbidity. Early diagnosis and treatment is the key to prevent re-hospitalizations and reduce healthcare costs. Biomarkers have long been established as highly sensitive and specific tools in diagnosing and prognosticating patients with HF. Reflecting distinct pathophysiological events and ongoing cellular insult, biomarkers have been proven superior to conventional laboratory tests. Availability of better assays and rapid analysis has allowed the use of biomarkers as point-of-care tests in the emergency department and at the patient's bed-side. Acute HF patients often go on to develop worsening renal function, termed as acute cardiorenal syndrome. The growing breadth of studies has shown the implications of combining multiple biomarkers to better chart outcomes and produce desirable results in such patients.

    Cerebral edema is a potentially life-threatening complication of acute liver failure, the syndrome of abrupt loss of liver function in a patient with a previously healthy liver. Although the prevalence of cerebral edema appears to be decreasing, patients with rapidly progressive (hyperacute) liver...... liver failure often can be temporarily controlled by manipulating body position, increasing the degree of sedation, and increasing blood osmolarity through pharmacologic means. However, these maneuvers often postpone, but do not eliminate, the risk of brainstem herniation unless orthotopic liver...... transplantation or spontaneous liver regeneration follows in short order. To buy time, the induction of therapeutic hypothermia (core temperature 32 degrees C-35 degrees C) has been shown to effectively bridge patients to transplant. Similar to the experience in patients with cerebral edema after other neurologic...

    Liver disease in pregnancy can be classified as predating, co-incidental or unique to pregnancy. Medications are often overlooked as a significant cause of liver disease. We present the case of a 39-year-old patient who presented at 20 weeks with jaundice, elevated liver enzymes, and abnormal liver function progressing eventually to fulminant hepatic failure. The patient was on methyldopa and labetalol from 12 weeks' gestational age. Liver biopsy was consistent with drug-induced liver injury. Both methyldopa and labetalol have been associated with hepatotoxicity including liver failure. This case highlights the importance of including medications as a cause of liver failure in pregnant patients.

    Viral hepatitis and toxins comprise most common causes of fulminate hepatic failure that are often diagnosed with standard laboratory tests. Herein we discuss a rare, difficult to diagnosis etiology of acute liver failure (ALF). A 62-year-old man presented with a two-week history of fever and fatigue. At four days before admission he became lethargic. His past medical and drug histories were unremarkable. Physical examination revealed generalized jaundice, fever and loss of consciousness. Laboratory tests showed elevated liver transaminases with direct hyper-bilirubinemia. Abdominal ultrasonography and CT scan showed hepatosplenomegaly and para-aortic abdominal lymphadenopathy. A further work-up included liver biopsy. The histopathology and imunohistochemistry was compatible with diffuse large B-cell lymphoma. He underwent high dose glucocorticoid therapy but his condition deteriorated rapidly and he died eight days after admission. ALF as an initial manifestation of malignant hepatic infiltration is extremely rare yet should be considered in all patients with unknown hepatic failure that are highly suspicious for malignant neoplasm.

    Severe cases of itraconazole-induced hepatotoxicity have been reported; however, these events are thought to occur very rarely. The available literature is comprised largely of individual case reports and small series that do not report the itraconazole serum concentration at the time of the severe adverse event or apply an objective scale to assess probability of the event being related to drug exposure. We report a case of severe hepatotoxicity after 6 months of itraconazole therapy for histoplasmosis, resulting in acute hepatic failure (aspartate transaminase >20× and alanine transaminase >15× upper limit normal), in the setting of therapeutic serum concentrations (5 mg/mL). Both the Naranjo probability scale and the Roussel Uclaf causality assessment method were used to assess the probability of a causality relationship showing a "probable" and "highly probable" association with itraconazole exposure, respectively. The available literature describing severe hepatotoxicity resulting in hepatic failure associated with itraconazole is also reviewed.

  11. Acute respiratory failure following ovarian hyperstimulation syndrome

    2013-03-01

    Full Text Available Ovarian hyperstimulation syndrome is a serious and potentially life-threatening physiological complication that may be encountered in patients who undergo controlled ovarian hyperstimulation cycles. The syndrome is typically associated with regimes of exogenous gonadotropins, but it can be seen, albeit rarely, when clomiphene is administered during the induction phase. Although this syndrome is widely described in scientific literature and is well known by obstetricians, the knowledge of this pathological and potentially life-threatening condition is generally less than satisfactory among physicians. The dramatic increase in therapeutic strategies to treat infertility has pushed this condition into the realm of acute care therapy. The potential complications of this syndrome, including pulmonary involvement, should be considered and identified so as to allow a more appropriate diagnosis and management. We describe a case of a woman with an extremely severe (Stage 6 ovarian hyperstimulation syndrome who presented ascites, bilateral pleural effusion and severe respiratory failure treated with non-invasive ventilation. The patient was admitted to the intensive care unit because of severe respiratory failure, ascites, and bilateral pleural effusion due to ovarian hyperstimulation syndrome. Treatment included non-invasive ventilation and three thoracentesis procedures, plus the administration of albumin, colloid solutions and high-dose furosemid. Severe form of ovarian hyperstimulation syndrome is observed in 0.5-5% of the women treated, and intensive care may be required for management of thromboembolic complications, renal failure and severe respiratory failure. Pulmonary intensive care may involve thoracentesis, oxygen supplementation and, in more severe cases, assisted ventilation. To our knowledge, there have been only two studies in English language medical literature that describe severe respiratory failure treated with non

    2016-08-15

    Acute respiratory failure (ARF) is a leading indication for performing critical care ultrasonography (CCUS) which, in these patients, combines critical care echocardiography (CCE) and chest ultrasonography. CCE is ideally suited to guide the diagnostic work-up in patients presenting with ARF since it allows the assessment of left ventricular filling pressure and pulmonary artery pressure, and the identification of a potential underlying cardiopathy. In addition, CCE precisely depicts the consequences of pulmonary vascular lesions on right ventricular function and helps in adjusting the ventilator settings in patients sustaining moderate-to-severe acute respiratory distress syndrome. Similarly, CCE helps in identifying patients at high risk of ventilator weaning failure, depicts the mechanisms of weaning pulmonary edema in those patients who fail a spontaneous breathing trial, and guides tailored therapeutic strategy. In all these clinical settings, CCE provides unparalleled information on both the efficacy and tolerance of therapeutic changes. Chest ultrasonography provides further insights into pleural and lung abnormalities associated with ARF, irrespective of its origin. It also allows the assessment of the effects of treatment on lung aeration or pleural effusions. The major limitation of lung ultrasonography is that it is currently based on a qualitative approach in the absence of standardized quantification parameters. CCE combined with chest ultrasonography rapidly provides highly relevant information in patients sustaining ARF. A pragmatic strategy based on the serial use of CCUS for the management of patients presenting with ARF of various origins is detailed in the present manuscript.

  13. A Rare Case of Propofol-Induced Acute Liver Failure and Literature Review

    Directory of Open Access Journals (Sweden)

    G. Kneiseler

    2010-02-01

    Full Text Available The incidence of drug-induced acute liver failure is increasing. A number of drugs can inhibit mitochondrial functions, alter β-oxidation and cause accumulation of free fatty acids within the hepatocytes. This may result in hepatic steatosis, cell death and liver injury. In our case, propofol, an anesthetic drug commonly used in adults and children, is suspected to have induced disturbance of the mitochondrial respiratory chain, which in consequence led to insufficient energy supply and finally liver failure. We report the case of a 35-year-old Caucasian woman with acute liver failure after anesthesia for stripping of varicose veins. Liver histology, imaging and laboratory data indicate drug-induced acute liver failure, presumably due to propofol. Hepatocyte death and microvesicular fatty degeneration of 90% of the liver parenchyma were observed before treatment with steroids. Six months later, a second biopsy was performed, which revealed only minimal steatosis and minimal periportal hepatitis. We suggest that propofol led to impaired fatty acid oxidation possibly due to a genetic susceptibility. This caused free fatty acid accumulation within hepatocytes, which presented as hepatocellular fatty degeneration and cell death. Large scale hepatocyte death was followed by impaired liver function and, consecutively, progressed to acute liver failure.

    Directory of Open Access Journals (Sweden)

    Yu-Bao Zheng

    Full Text Available Uncontrolled hepatic immunoactivation is regarded as the primary pathological mechanism of fulminant hepatic failure (FHF. The major acute-phase mediators associated with FHF, including IL-1β, IL-6, and TNF-α, impair the regeneration of liver cells and stem cell grafts. Amniotic-fluid-derived mesenchymal stem cells (AF-MSCs have the capacity, under specific conditions, to differentiate into hepatocytes. Interleukin-1-receptor antagonist (IL-1Ra plays an anti-inflammatory and anti-apoptotic role in acute and chronic inflammation, and has been used in many experimental and clinical applications. In the present study, we implanted IL-1Ra-expressing AF-MSCs into injured liver via the portal vein, using D-galactosamine-induced FHF in a rat model. IL-1Ra expression, hepatic injury, liver regeneration, cytokines (IL-1β, IL-6, and animal survival were assessed after cell transplantation. Our results showed that AF-MSCs over-expressing IL-1Ra prevented liver failure and reduced mortality in rats with FHF. These animals also exhibited improved liver function and increased survival rates after injection with these cells. Using green fluorescent protein as a marker, we demonstrated that the engrafted cells and their progeny were incorporated into injured livers and produced albumin. This study suggests that AF-MSCs genetically modified to over-express IL-1Ra can be implanted into the injured liver to provide a novel therapeutic approach to the treatment of FHF.

  16. Massive hepatic cyst presenting as right-sided heart failure.

    2010-01-30

    A 70-year-old woman presented with clinical features of right heart failure. Cardiopulmonary investigations included an echocardiogram, which showed a hepatic cyst compromising venous return and affecting right atrial filling and a CT abdomen showed a 15.5 x 11.5 cm-cystic mass involving the right hepatic lobe and compressing the right atrium. Percutaneous drainage of the cyst was performed. This led to complete resolution of symptoms but these recurred as the fluid re-accumulated. Subsequent definitive treatment with excision of the cyst was undertaken with symptomatic cure. This case is the first report of a hepatic cyst presenting as right heart due to compression of the right atrium.

    2017-01-01

    Introduction Acute Renal Failure (RF) is a rare but well recognized complication of Dengue Infection (DI). There has been paucity of published data regarding renal involvement in DI. Aim The aim of the present study was to elucidate different clinical presentations, disease outcomes of DI. To study the frequency, severity and predictors of RF in DI. Materials and Methods Patients diagnosed either as Dengue Fever (DF) or Dengue Haemorrhagic Fever/Dengue Shock Syndrome (DHF/DSS) respectively were enrolled for this study. The diagnostic criteria for DI were febrile illness associated with one of the following: 1) detection of dengue-specific IgM capture antibody or Non-Structural Protein1 (NS1) antigen; or 2) a four-fold or greater increase of dengue-specific IgG capture antibody by ELISA and haemoagglutination inhibition assay. Patients were diagnosed as having Acute RF, if serum creatinine was >1.2 mg/dl or who showed improvement by 50% in serum creatinine from the initial value. It is an observational study of medical charts, data of age, gender, and medical history of any underlying diseases in association with the severity of DI of each patient recorded. All of the laboratory results were collected. Parameters that influenced the clinical presentations and outcomes for development of classical DF or DHF/DSS in patients with or without RF were analysed and compared. Descriptive and inferential statistical analysis was carried. The Statistical software namely SAS 9.2, SPSS 15.0, Stata 10.1, Med Calc 9.0.1, Systat 12.0 and R environment ver.2.11.1 were used. Results Most common symptoms were fever followed by headache and pain in abdomen. Among the patients with RF, all patients had recovery. The patients with DHF/DSS were more susceptible to develop renal failure compared to DF group. There were statistically significant higher frequencies of renal failure, haemoconcentration, thrombocytopenia, low serum cholesterol. Patients in the RF group also had significantly

    The intravascular administration of iodinated radiocontrast media can lead to acute renal dysfunction. Even small changes in renal function have been associated with increased morbidity and mortality, making the prevention of radiocontrast nephropathy of paramount importance. This review summarizes the principal risk factors for radiocontrast nephropathy and evidence-based preventive strategies that should be used to limit its occurrence. Risk factors for radiocontrast nephropathy include preexistent kidney disease, diabetes mellitus, dose of radiocontrast used, advanced congestive heart failure, and intravascular volume depletion. Proven preventive measures include volume expansion with intravenous saline or sodium bicarbonate and the use of low-osmolar or iso-osmolar radiocontrast media. Studies evaluating N-acetylcysteine have been conflicting, with meta-analyses suggesting a small beneficial effect. Studies of other pharmacologic agents have not demonstrated clinical benefit.

    Full Text Available Fulminant hepatic failure (FHF is characterized by massive hepatocellular injury, whose physiopathology is still unclear. Hepatitis B (HBV is probably the most common viral cause of FHF, while hepatitis A (HAV virus seem occurs less frequently. However, the host and viral factors that determine the outcome of these infections are poorly understood. In the present study, viral load and genotyping determining regions of HAV and HBV genomes were sequenced. Eight FHF patients and one patient with severe acute hepatitis (SAH were included. Liver and blood samples were collected during liver transplantation or necropsy procedures. HAV-RNA and HBV-DNA were extracted from serum, biopsy and paraffin liver. Nucleotide sequencing of HAV-RNA was performed from VP1/2A and HBV-DNA from PreS/S region. The amplified samples were quantified by Real-Time PCR. The cases of HAV infection were due to subgenotype IA. The cases of HBV infection were due to genotype A2 and D4. The case of HAV/HBV coinfection was infected by genotype IA and D3. Hepatitis A and B infection were associated with genotypes most prevalent in Brazil. In hepatitis A infection the mean of period evolution was 13 days. In hepatitis B, FHF patients infected by genotype D have a shorter period of evolution than FHF patients infected by genotype A (mean 15 v. 53 days. There was no association with genotype-determining region with the severity of hepatitis, however nucleotide differences and high viral load could be observed among FHF.

    Full Text Available BACKGROUND: We have noticed a recent rise in the incidence and severity of acute renal failure (ARF in malaria. AIM: To study the incidence, severity and outcome of ARF in malaria. SETTING and DESIGN: It is a retrospective analysis of data of one year from a tertiary medical centre in a metropolitan city. MATERIALS AND METHODS: Patients with ARF and smear positive malaria were evaluated. STATISTICAL ANALYSIS: Results were expressed as mean, range and standard deviation. RESULTS: Out of 402 detected smear positive malaria, 24 had ARF. Eighteen were of the age group 21-40 years. Plasmodium falciparum (PF was detected in 16, Plasmodium vivax in three, and mixed infection in five. Non-oliguric ARF was seen in 14. Eighteen showed severe ARF (Serum creatinine >5 mg%. Twenty-two patients needed dialysis. Prolonged ARF lasting for 2-6 weeks was seen in eight. Seventeen patients recovered completely, while seven showed fatal combination of disseminated intravascular coagulation (DIC, acute respiratory distress syndrome (ARDS, severe ARF and PF malaria. No response was seen to chloroquine and artesunate given alone and twenty patients required quinine. CONCLUSION: ARF necessitating dialysis was seen in 92% of patients with ARF in malaria. PF infection, severe ARF, DIC and ARDS were poor prognostic factors. Resistance was noted to both chloroquine and artesunate.

    Full Text Available Introduction: The application of continuous positive airway pressure (CPAP is one of the most important therapeutic interventions used in patients with acute respiratory failure (ARF secondary to acute cardiogenic pulmonary edema (ACPE. Thanks to its positive effects on both hemodynamics and ventilation, CPAP improves clinical and blood-gas parameters. Compared with standard oxygen therapy, use of CPAP is associated with decreased mortality and reduced need for intubation in these patients. Aim of the study: This review examines the principles of CPAP, techniques and equipment used to deliver it, and clinical applications. Special emphasis is placed on CPAP delivered with the Boussignac device. Discussion and conclusions: In emergency departments, this simple, lightweight, disposable device has proved to be well tolerated and similar to Venturi-like flow generators in terms of effectiveness. These findings suggest that Boussignac CPAP might be useful for managing ARF in non-critical care areas where other more complicated CPAP equipment (Venturi-like flow generators and ventilators are not available (for example, in general medical wards.

    Hepatic encephalopathy is a serious neuropsychiatric disorder usually affecting either acute or chronic hepatic failure patients. Hepatic encephalopathy was replicated in a validated rat model to assess the potential protective efficacy of tranilast against experimentally induced hepatic encephalopathy. Thioacetamide injection significantly impaired hepatic synthetic, metabolic and excretory functions with significant increase in serum NO, IL-6 and IL-13 levels and negative shift in the oxidant/antioxidant balance. Most importantly, there was a significant increase in serum ammonia levels with significant astrocytes' swelling and vacuolization; hallmarks of hepatic encephalopathy. Tranilast administration (300 mg/kg, orally) for 15 days significantly improved hepatic functions, restored oxidant/antioxidant balance, reduced serum NO, IL-6 and IL-13 levels. Meanwhile, serum ammonia significantly declined with significant reduction in astrocytes' swelling and vacuolization. Several mechanisms can be implicated in the observed hepato- and neuroprotective potentials of tranilast, such as its anti-inflammatory potential, its antioxidant potential as well as its immunomodulatory properties.

    Abacavir hypersensitivity is a rare, yet significant adverse reaction that results in a spectrum of physical and laboratory abnormalities, and has been postulated to stem from a variety of aetiological factors. The major histocompatibility complex haplotype human leucocyte antigen (HLA)-B5701 is a significant risk factor in development of hypersensitivity reactions, yet only 55% of HLA-B5701+ individuals develop such reactions, suggesting a multifactorial aetiology. Nevertheless, prospective screening and avoidance of abacavir in these patients has limited adverse events. Within this spectrum of adverse events, abacavir-induced liver toxicity is exceedingly rare and reported events have ranged from mild elevations of aminotransferases to fulminant hepatic failure. We report the case of a 50-year-old Caucasian woman with a history significant for HIV, hepatitis C virus and a HLA-B5701+ status, transferred to our emergency department in a hypotensive state and found to have acute liver failure, acute renal failure and significant rhabdomyolysis following a change of highly active antiretroviral therapy regimen.

    Objective To study the theraputic effect of extracorporeal liver perfusion on the treatment of acute liver failure. Methods Mongrel dogs weighing 12-14*!kg were selected. Hepatic failure was induced by an end-to-side portacaval shunt. The common hepatic and gastroduodenal arteries were occluded for 2 hours. To the control group (n=7), the dogs received standard medical therapy . To the treating group (n=10), the dogs received extracorporeal kidney and liver perfusion at the onset of the occlusion of the hepatic artery. During the liver support, the animals were frequently monitored regarding their clinical state, liver function, biochemical and hematological parameters. Results After the occlusion of the liver blood flow, all dogs died within 3-7.5 hours. The average survival time was (5.7±1.2) hours. Serum levels of ALT, AST, LDH and ammonia increased significantly. In the treating group, the dogs died within 7-10.5 hours. The average survival time was 8.6±1.1 hours. There were no significant diferences in serum levels of ALT, AST, LDH between the two groups(P>0.05). There were dramatic diferences in blood Ammonia level, PT, FIB between the two groups(P<0.05). The survival time was longer in treating group. The animals' blood pressure were more stable in the treating group than that in the control group. Conclusion The modified xenogenic liver perfusion can provide necessary hepatic function for the acute liver failure dogs.

    Full Text Available Diabetes mellitus (DM is a metabolic disorder resulting from a defect in Insulin secretion, insulin action or both. Despite the fact that it has a worldwide high prevalence, morbidity and mortality, it is regarded as a non–curable but controllable disease. In addition to different synthetic drugs, plant remedies and dietary traditions play an effective role in treatment. Teucrium polium L. is one of the 300 species of the genus Teucrium and found mainly in the Mediterranean and Western lrano- Turanian sphere. lt is widely distributed in Jordan and Palestine. The leaves, 1-3 cm long, are sessile, oblong or linear, the stems are ending in shortly paniculate or corymbose inflorescences, and corolla is white or pale cream colored. This case describes a 74year old man with diabetes since 20 years. He was treated by glibenclamide 5mg/day. He stopped this drug and started daily consumption of tea containing the medicinal plant, teucrium polium. One month after initiation of this therapy, he developed an acute icteric hepatitis like illness. After 8 weeks, the patient recovered clinically and bilirubin, ALT and AST levels were normal.

  6. [New options in the treatment of acute heart failure].

    2014-06-01

    Acute heart failure is defined as the acute onset of symptoms due to hear failure necessitating emergency therapy. The in-hospital mortality rate ranges up to 10 % and in cardiogenic shock is 50-70 %. In acute heart failure, rapid diagnosis and causal therapy are necessary to avoid cardiogenic shock. In cases of acute coronary syndromes, primary percutaneous intervention should be performed immediately. Medical and apparative treatment strategies focus on decreasing pulmonary congestion, afterload, and neurohormonal activation in order to improve hemodynamics and reduce symptoms of dyspnea. In contrast to chronic heart failure, no medical therapy has been able to reduce mortality rates in acute heart failure. However, new medical therapies should at least improve clinical symptoms of congestion and favorably reduce cardiovascular events, re-hospitalization, and mortality rates.

    AIM: To describe the diagnostic criteria for acute liver failure due to Wilson disease (WD), which is an uncommon cause of acute liver failure (ALF).METHODS: We compared findings of patients presenting with ALF due to WD to those with ALF of other etiologies.RESULTS: Previously described criteria, such as low alkaline phosphatase activity, ratio of low alkaline phosphatase to total bilirubin or ratio of high aspartate aminotransferase (AST) to alanine aminotransferase (ALT), failed to identify patients with ALF due to WD. There were significant differences in low ALT and AST activities (53 ± 43 vs 1982 ± 938, P < 0.0001 and 87 ± 44 vs 2756 ± 2941, P = 0.037, respectively), low choline esterase activity (1.79 ± 1.2 vs 4.30 ± 1.2, P = 0.009), high urine copper concentrations (93.4 ± 144.0 vs 3.5 ± 1.8, P = 0.001) and low hemoglobin (7.0 ± 2.2 vs 12.6 ± 1.8, P < 0.0001) in patients with ALF caused by WD as compared with other etiologies. Interestingly, 4 of 7 patients with ALF due to WD survived without liver transplantation.CONCLUSION: In ALF, these criteria can help establish a diagnosis of WD. Where applicable, slit-lamp examination for presence of Kayser-Fleischer rings and liver biopsy for determination of hepatic copper concentration still remain important for the diagnosis of ALF due to WD. The need for liver transplantation should be evaluated carefully as the prognosis is not necessarily fatal.

    Acute pulmonary failure is a very serious cause of respiratory failure. Radiological diagnosis occupies a central position in intensive-care monitoring. X-ray film of the thorax is performed not only for detecting any complications, but mainly for noninvasive and semiquantitative determination of the extravascular pulmonary fluid and hence of the fluid balance. Other methods such as MR or methods of nuclear medicine have not acquired substantial importance in respect of diagnosis and monitoring acute pulmonary failure. (orig./GDG).

  9. Life Saving Plasmapheresis for the Management of Hemolytic Crisis and Acute Liver Failure in Wilson’s Disease

    Full Text Available Wilson's disease, caused by a deficient cellular copper export system, is transmitted as an autosomal recessive inherited disorder and results in copper accumulation in liver and other organs, particularly in brain. Acute hepatic failure and severe Coombs' negative hemolysis may occur in the course of the disease which has a poor prognosis and most patients do not survive the crisis. Only liver transplantation has been recommended as an effective medical intervention. Herein, we presented a 25-year-old woman with impaired consciousness, acute hepatic failure and hemolysis who was treated with plasmapheresis and albumin replacement. Beside improvement in medical condition, serum copper and hemolysis decreased significantly and renal function was preserved. We concluded that plasmapheresis may be a life saving intervention during fulminant hepatic failure of Wilson's disease.

    2011-01-01

    Autoimmune hepatitis (AIH) is a disease of unknown etiology, its hallmark being ongoing hepatic inflamma-tion. By its very nature, it is a chronic condition, al-though increasingly, we are becoming aware of patients with acute presentations, some of whom may have liver failure. There are very limited published data on patients with AIH with liver failure at initial diagnosis, which consist mostly of small retrospective studies. As a consequence, the clinical features and optimal management of this cohort remain poorly defined. A subset of patients with AIH who present with liver failure do respond to corticosteroids, but for the vast majority, an urgent liver transplantation may offer the only hope of long-term survival. At present, there is uncertainty on how best to stratify such a cohort into responders and non-responders to corticosteroids as soon as possible after hospitalization, thus optimizing their management. This editorial attempts to answer some of the unre-solved issues relating to management of patients with AIH with liver failure at initial presentation. However, it must be emphasized that, at present, this editorial is based mostly on small retrospective studies, and it is an understatement that multicenter prospective studies are urgently needed to address this important clinical issue.

    Patients with fulminant hepatic failure (FHF) frequently develop cerebral edema and intracranial hypertension. The aim of this study was to evaluate circulating S-100b and neuron-specific enolase (NSE) levels as markers of neurological outcome in patients with FHF. In a subgroup of patients......, the cerebral flux of S-100b and NSE was measured. We included 35 patients with FHF, 6 patients with acute on chronic liver disease (AOCLD), 13 patients with cirrhosis of the liver without hepatic encephalopathy, and 8 healthy subjects. Blood samples were obtained from catheters placed in the radial artery...... and internal jugular bulb. The net cerebral flux of S-100b and NSE was measured, and the effect of short-term hyperventilation, as well as the effect of high-volume plasmapheresis, on circulating levels of these two biomarkers was determined. Blood levels of S-100b were greater in patients with FHF and AOCLD...

    Full Text Available Background/Aim. Hemodynamic stress is the leading cause of acute renal failure (ARF in premature neonates. Incidence of ARF in this population is between 8 and 24%. The aim of this study was to determine the frequency of presence of ARF in premature neonates, as well as its impact on their survival. Methods. A retrospective study of 114 premature neonates [(gestational age, GA less than 37 gestation weeks (gw] admitted to the Intensive Care Unit (ICU at the Pediatric Clinic, Institute of Child and Youth Healthcare of Vojvodina in 2007 was conducted. Serum creatinine, urea and bilirubine were determined on the 3rd day of life in 65 newborns who met inclusion criteria. ARF was diagnosed in 16 newborns (n=16/65; 25%. Results. The premature neonates with ARF had significantly lower GA [<28 gw - 8/16 (50% vs. 5/49 (10%; p < 0.05], birth weight (BW (1 265 g vs. 1615 g; p < 0.05 and systolic blood pressure (43.37 mm Hg vs. 52.7 mmHg; p < 0.05 than ones without ARF. Non-olyguric ARF was diagnosed in 62% of newborns with ARF (n=10/16, while the rest had the olyguric type (n = 6/16; 38%. Twenty-five percent of premature neonates with ARF (n = 4/16 died in contrast to 10% of premature neonates without ARF (n = 5/49. ARF was treated conservatively in all but 3 cases when peritoneal dialysis was performed. Renal function has recovered completely in all of the survivors. In order to determine their predictivity in relation to ARF, following parameters were analyzed: GA, BW < 1 500 g, presence of concomitant sepsis and intracranial hemorrhage grade III/IV. BW < 1 500 g demonstrated the highest sensitivity (se 0.75, while GA < 28 gw, sepsis and intracranial hemorrhage grade III/IV showed high specificity (sp = 0.90, 0.89 0.88, respectively. Conclusion. Acute renal failure frequently occurs in population of premature neonates and requires meticulous fluid and electrolyte balance, especially in the case of low birth weight and extreme immaturity.

    Severe acute hepatitis of unknown etiology is difficult to treat and often progresses to subacute fulminant hepatitis or late-onset hepatic failure. A 45-year-old wellnourished, healthy man had progressive fatigue and his liver function tests showed severe liver dysfunction. The etiology of sever acute cholestatic hepatitis was unknown. The liver function tests normalized gradually, which excluded high persistent total bilirubin after starting on predonine. A liver biopsy showed chronic active hepatitis with mild fibrosis (A2, F1). Oral Inchinko-to, a Chinese herbal medicine, at 7.5 g daily was prescribed. The treatment was effective with no adverse effects. We present a successfully treated case and discuss hepatoprotective and choleretic effects of Inchinko-to.

    Full Text Available Congenital Hepatic Fibrosis (CHF is a rare disease that affects both the liver and kidneys.  Congenital hepatic fibrosis (CHF is an autosomal recessive inherited malformation defined pathologically by a variable degree of periportal fibrosis and irregularly shaped proliferating bile ducts. Affected individuals also have impaired renal function, usually caused, in children and teenagers, by an autosomal recessive polycystic kidney disease (ARPKD. Impaired renal function associated with CHF in adults is caused by an autosomal dominant polycystic kidney disease (ADPKD. Case presentation: We report the case of a 8-year-old Iranian girlwas admitted to our hospital for evaluation ofrenal failure. In patient hepatomegaly was noted incidentally on a routine physical examination and then kidney biopsy showed global sclerosis and   A liver biopsy revealed proliferation of collagen fibres surrounding the portal area, a finding that was compatible with congenital hepatic fibrosisand our patient was scheduled for kidney and  liver transplantation. Conclusion: The relationship of ARPKD to CHF is the subject of substantial controversy. Some clinicians suggest that the two conditions represent one disorder with a range of clinical/pathological presentations Key word: Congenital Hepatic Fibrosis Polycystic Kidney Disease, CRF.

    AIM: Vasodilatation and increased capillary permeability have been proposed to be involved in the pathogenesis of acute and chronic form of hepatic encephalopathy.Prostacyclin (PGI2) and nitric oxide (NO) are important contributors to hyperdynamic circulation in portal hypertensive states. Our previous study showed that chronic inhibition of NO had detrimental effects on the severity of encephalopathy in thioacetamide (TAA)-treated rats due to aggravation of liver damage. To date, there are no detailed data concerning the effects of PGI2 inhibition on the severity of hepatic encephalopathy during fulminant hepatic failure.METHODS: Male Sprague-Dawley rats weighing 300-350 g were used. Fulminant hepatic failure was induced by were divided into two groups to receive intraperitoneal saline (N/S, n = 20) for 5 d, starting 2 d before TAA administration. Severity of encephalopathy was assessed by the counts of motor activity measured with Opto-Varimex animal activity meter. Plasma tumor necrosis factor-α(TNF-α, an index of liver injury) and 6-keto-PGF1α (a metabolite of PGI2) levels were measured by enzyme-linked immunosorbent assay.RESULTS: As compared with N/S-treated rats, the mortality rate was significantly higher in rats receiving indomethacin (20% vs5%, P<0.01). Inhibition of PGI2 created detrimental effects on total movement counts (indomethacin vs N/S:438±102 vs841±145 counts/30 min, P<0.05). Rats treated with indomethacin had significant higher plasma levels of TNF-α (indomethacin vsN/S: 22±5 vs 10±1 pg/mL, P<0.05)and lower plasma levels of 6-keto-PGF1α (P<0.001), but not total bilirubin or creatinine (P>0.05), as compared with rats treated with N/S.CONCLUSION: Chronic indomethacin administration has detrimental effects on the severity of encephalopathy in TAA-treated rats and this phenomenon may be attributed to the aggravation of liver injury. This study suggests that PGI2 may provide a protective role in the development of fulminant

    2013-04-01

    Full Text Available Rhabdomyolysis is caused by muscle breakdown resulting in the release of myoglobin into the systemic circulation. Acute renal failure results from the nephrotoxicity of myoglobin. Heroin use is one of the causes of rhabdomyolysis and acute renal failure. Aim: The aim of this literature review was highlight the importance of early recognition and treatment by a nurse of acute renal failure from rhabdomyolysis after heroin. Method: The method followed in this review was based on retrospective studies and research, conducted during the period 2000-2012 and retracted from the international databases Medline, Pubmed, Cinahl and the Greek database Iatrotek on acute renal failure from rhabdomyolysis after heroin use. Key-words were used: acute renal failure, rhabdomyolysis, heroin, international guidelines, based-evidence nursing care. Results: The clinical presentation occurs with muscle pain, muscle weakness, and brown-redish urine. High values of CPK and myoglobin make the diagnosis. Toxicology tests confirm heroin use. For the treatment is required naloxone administration, the rapid hydration of the patient, alkalinization of urine, good diuresis, regulation of electrolyte disturbances and dialysis if necessary. Conclusions: Early recognition and treatment of acute renal failure from rhabdomyolysis after heroin use is vital for the survival of the patient. It is necessary to educate nurses on specific issues such as acute renal failure from rhabdomyolysis after heroin use and the implementation of protocols for the treatment and cure.

    We have prospectively studied 158 cases of acute hepatitis delta observed during the last 7 years in a general hospital. Among them 136 were male and 22 female. The mean age was 22.7 years with a range between 16 and 61 years. The epidemiologic factors were drug addiction by parenteral route in 145 cases (92%), sexual transmission in 5 (3%), post transfusional in 2 (1%) and unknown in 6 (4%). With respect to the delta type infection, 105 cases (66%) were coinfections with type B and delta, and 53 patients had a type delta superinfection (34%). The clinical course was a fulminant hepatitis in three cases (two cases of coinfection B and delta an one case of delta superinfection), and an acute benign hepatitis in 155 patients. The follow-up of 118 patients revealed that 96% of coinfections by type B and delta evolved to the chronicity showing findings of active chronic hepatitis or hepatic cirrhosis. It should be noted that in 4 cases of superinfection delta type (11%) the HBsAg was negative after several months of positivity. In these patients the level of transaminases normalized and the hepatic histology evidenced alterations of chronic active hepatitis (2 cases) and hepatic cirrhosis (2 cases) without identification of tissular delta antigen.

    Full Text Available "nAcute renal failure (ARF following cardiac surgery occurs in 1 to 10% of patients. Patients who develop ARF have higher rates of mortality. This study was undertaken to estimate the role of perioperative variables in predicting of post cardiac surgery ARF. We studied a cohort of 398 adult patients who underwent cardiac surgery at our institution from February 2004 to February 2006. Adult patients who were scheduled for cardiac valvular surgery, coronary artery bypass grafting (CABG or both, with or without cardiopulmonary bypass (CPB were included. Exclusion criteria were death within two days of operation (n= 8, incomplete patient data, and preexisting renal dysfunction and dialysis requirement or a baseline serum creatinine > 4 mg/dl. Age, sex, left ventricular ejection fraction, diabetes, preoperative, presence of proteinuria (on dipstick, type of surgery, use of CPB and duration of surgery were recorded. A logistic regression analysis was performed to assess independent contribution of variables in the risk of ARF. A binary logistic regression revealed age was an independent predictor of ARF (P < 0.05. When both all variables were included in a multinominal logistic regression model, preoperative proteinuria independently predicted ARF (Odds ratio= 3.91, 95% CI: 1.55-9.91, P = 0.004. Our results revealed that special considerations should be given to elderly and patients with proteinuria when managing post cardiac surgery ARF.

    AIM: To investigate the long-term results of liver transplantation (LT) for non-acetaminophen fulminant hepatic failure (FHF).METHODS: Over a 20-year period, 29 FHF patients underwent cadaveric whole LT. Most frequent causes of FHF were hepatitis B virus and drug-related (not acetaminophen) liver failure. All surviving patients were regularly controlled at the out-patient clinic and none was lost to follow-up. Mean follow-up was 101 mo.RESULTS: One month, one-, five- and ten-year patient survival was 79%, 72%, 68% and 68%, respectively.One month, one-, five- and ten-year graft survival was 69%, 65%, 51% and 38%, respectively. Six patients needed early (< 2 mo) retransplantation, four for primary non-function, one for early acute refractory rejection because of ABO blood group incompatibility,and one for a malignant tumor found in the donor.Two patients with hepatitis B FHF developed cerebral lesions peri-transplantion: One developed irreversible and extensive brain damage leading to death, and one suffered from deep deficits leading to continuous medical care in a specialized institution.CONCLUSION: Long-term outcome of patients transplanted for non-acetaminophen FHF may be excellent. As the quality of life of these patients is also particularly good, LT for FHF is clearly justified, despite lower graft survival compared with LT for other liver diseases.

    The cause of organ failure is enigmatic for many degenerative diseases, including end-stage liver disease. Here, using a CCl4-induced rat model of irreversible and fatal hepatic failure, which also exhibits terminal changes in the extracellular matrix, we demonstrated that chronic injury stably reprograms the critical balance of transcription factors and that diseased and dedifferentiated cells can be returned to normal function by re-expression of critical transcription factors, a process similar to the type of reprogramming that induces somatic cells to become pluripotent or to change their cell lineage. Forced re-expression of the transcription factor HNF4α induced expression of the other hepatocyte-expressed transcription factors; restored functionality in terminally diseased hepatocytes isolated from CCl4-treated rats; and rapidly reversed fatal liver failure in CCl4-treated animals by restoring diseased hepatocytes rather than replacing them with new hepatocytes or stem cells. Together, the results of our study indicate that disruption of the transcription factor network and cellular dedifferentiation likely mediate terminal liver failure and suggest reinstatement of this network has therapeutic potential for correcting organ failure without cell replacement.

    One hundred ten consecutive patients (60 males and 50 females; age, mean +/- standard deviation [SD], 22.6 +/- 6.4 years; range 16-48 years) who were clinically diagnosed with sporadic acute hepatitis between December 2004 and January 2005 in Ulaanbaatar, Mongolia, were studied. IgM antibodies to hepatitis A virus were detected in 18 patients (16.4%), IgM antibodies to hepatitis B core (anti-HBc IgM) in 38 patients (34.5%) including two patients with concurrent hepatitis delta virus (HDV) infection, and hepatitis C virus RNA in nine patients (8.2%). There were 30 hepatitis B virus (HBV) carriers who had detectable hepatitis B surface antigen and antibodies to HDV but were negative for anti-HBc IgM, suggesting that they acquired type D acute hepatitis due to superinfection of HDV on a background of chronic HBV infection. None had IgM antibodies to hepatitis E virus (HEV). Consequently, 16.4, 32.7, 6.4, 1.8, and 27.3% of the patients were diagnosed as having acute hepatitis of type A, B, C, type B + D (HBV/HDV coinfection), and type D (superinfection of HDV), respectively. The cause of hepatitis was not known in the remaining 17 patients (15.5%). All 18 HAV isolates were genotyped as IA, all 9 HCV isolates were genotyped as 1b, and all 32 HDV isolates were classified into genotype I. The distribution of HBV genotypes among the 67 HBV isolates was A (1.5%, n = 1) and D (98.5%, n = 66). The present study indicates that de novo infections of HAV, HBV, HCV, and HDV are prevalent among young adults in Mongolia.

    BACKGROUND & AIMS Hepatocyte transplantation is a potential therapeutic approach for liver disease. However, most patients with chronic hepatic damage have cirrhosis and fibrosis, which limit the potential for cell-based therapy of the liver. The development of an ectopic liver as an additional site of hepatic function represents a new approach for patients with an end-stage liver disease. We investigated the development and function of liver tissue in lymph nodes in mice with liver failure. METHODS Hepatocytes were isolated from 8 to 12-week-old mice and transplanted by intraperitoneal injection into 8- to 12-week-old Fah-/- mice, a model of the human liver disease tyrosinemia type I. Survival was monitored and the locations and functions of the engrafted liver cells were determined. RESULTS Lymph nodes of Fah-/- mice were colonized by transplanted hepatocytes; Fah+ hepatocytes were detected adjacent to the CD45+ lymphoid cells of the lymphatic system. Ten weeks after transplantation, these mice had substantial improvements in serum levels of transaminases, bilirubin, and amino acids. Homeostatic expansion of donor hepatocytes in lymph nodes rescued the mice from lethal hepatic failure. CONCLUSIONS Functional ectopic liver tissue in lymph nodes rescues mice from lethal hepatic disease; lymph nodes might therefore be used as sites for hepatocyte transplantation. PMID:21070777

    Full Text Available Introduction. Experience with lamivudine treatment for acute severe hepatitis B is limited. Fulminant hepatitis develops in 1% of immunocompetent patients with acute hepatitis B. Objective. The aim of this study was to evaluate the efficacy of lamivudine in the treatment of severe acute hepatitis B (SAHB in immunocompetent adult patients. Methods. Between January 2006 and May 2013 at the Clinic for Infectious Diseases Banja Luka, 13 patients with SAHB were treated with lamivudine at a dose of 100 mg per day. All 13 patients fulfilled at least two of three default criteria: 1. hepatic encephalopathy; 2. total bilirubin greater than 210 μmol/L; and 3. severe coagulopathy (international normalized ratio - INR ≥1.5 or prothrombin time - PT <40%. The criteria were defined according to the experiences reported in the study of Schmilovitz-Weiss et al. ”Lamivudine treatment for severe acute hepatitis B“. Nine patients had a rapid rise in the total bilirubin and decrease of alanine aminotransferase level, which escalated risk for development of fulminant hepatitis. Results. Within 1-6 months, HBsAg was undetectable in 12 of 13 examined patients. Protective anti-HBsAg developed in 10 of them during 2-14 months. Two patients did not develop protective antibodies, but the result of the analysis of PCR HBV DNA was repeatedly negative. Corticosteroids were shortly used in two patients. One patient died four days after starting the therapy. Lamivudine treatment was well tolerated by all patients. Conclusion. Early treatment with lamivudine can reduce the risk of progression to fulminant hepatitis in patients with SAHB.

    Full Text Available Malaria has protean clinical manifestations and renal complications, particularly acute renal failure that could be life threatening. To evaluate the incidence, clinical profile, out-come and predictors of mortality in patients with malarial acute renal failure, we retrospectively studied the last two years records of malaria induced acute renal failure in patients with peripheral smear positive for malarial parasites. One hundred (10.4% (63 males, 37 females malaria induced acute renal failure amongst 958 cases of acute renal failure were evaluated. Plasmodium (P. falciparum was reported in 85%, P. vivax in 2%, and both in 13% patients. The mean serum creatinine was 9.2 ± 4.2 mg%, and oligo/anuria was present in 82%; 78% of the patients required hemodialysis. Sixty four percent of the patients recovered completely, 10% incompletely, and 5% developed chronic kidney failure; mortality occurred in 21% of the patients. Low hemoglobin, oligo/anuria on admission, hyperbilirubinemia, cerebral malaria, disseminated intravascular coa-gulation, and high serum creatinine were the main predictors of mortality. We conclude that ma-laria is associated with acute renal failure, which occurs most commonly in plasmodium falci-parum infected patients. Early diagnosis and prompt dialysis with supportive management can reduce morality and enhance recovery of renal function.

    Full Text Available Background/Aims: Acute liver failure (ALF in pregnancy is often associated with a poor prognosis. In this single-center observational study we aim to study the incidence, causes, and factors affecting mortality in pregnant women with ALF. Patients and Methods: Sixty-eight pregnant women reporting with clinical features of liver dysfunction were enrolled as "cases." Their clinical course was followed and laboratory studies were performed. The presence of ALF was defined as the appearance of encephalopathy. The results were compared with a "control" group of 16 nonpregnant women presenting with similar complaints. The cases were further subdivided into two groups of "survivors" and "nonsurvivors" and were compared to find out the factors that contribute to mortality. Results: ALF was seen in significantly more number of pregnant women than the controls (P = 0.0019. The mortality rate was also significantly higher (P = 0.0287. Hepatitis E virus (HEV caused jaundice in a higher number of pregnant women (P < 0.001. It also caused ALF in majority (70.3% of pregnant women, but HEV infection was comparable between the survivors and nonsurvivors (P = 0.0668, hence could not be correlated with mortality. Conclusions: Pregnant women appear to be more susceptible for HEV infection and development of ALF. The mortality of jaundiced pregnant women increased significantly with appearance of ALF, higher bilirubin, lower platelet count, higher international normalized ratio, and spontaneous delivery.

    Full Text Available OBJECTIVES: To evaluate the clinical effects of blood purification for treating fulminant hepatic failure (FHF. METHODS: Thirty-three severe FHF patients with hepatic encephalopathy (HE above grade III were subjected to a combined blood purification treatment in addition to the comprehensive liver protection therapy. Patients underwent continuous hemofiltration on a daily basis during the daytime followed by sequential treatment with plasma exchange or hemodialysis every 2-3 days. The therapeutic effects of this treatment were evaluated. RESULTS: After treatment with blood purification, restoration of consciousness (those who abandoned the treatment without restoration of consciousness were excluded was achieved in 6 of 8 cases (75% in acute liver failure (ALF group, 3 of 3 cases (100% in subacute liver failure (SALF group, and 9 of 14 cases (64.29% in acute/subacute on chronic liver failure (A/SCLF group. Of all cases, 11 patients restored consciousness after 7 days in a coma. The rate of long-term survival (those who abandoned the treatment were excluded was 3/7 (42.86% for ALF group, 2/2 (100% for SALF group, and 1/11 (9.09% for A/SCLF group. The levels of hemoglobin and platelet in peripheral blood were significantly reduced after blood purification. CONCLUSIONS: Treatment of FHF patients with daily continuous hemofiltration during the daytime is effective in treating HE and in improving health status in the early stages of the disease. Long-term prognosis also benefits from this treatment. The rate of consciousness recovery and long-term survival is highest in SALF group followed by ALF group. This treatment is less effective in A/SCLF patients. It should be noted that blood purification procedure may cause damage to blood cells.

  8. Acute hepatitis B or exacerbation of chronic hepatitis B-that is the question

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Hepatitis B virus (HBV) infection constitutes a serious global health problem. In countries with intermediate or high endemicity for HBV, exacerbations of chronic hepatitis B may be the first presentation of HBV infection. Some of these patients may be diagnosed mistakenly as having acute hepatitis B. Accurate diagnosis in these cases is very important for deciding whether to start treatment or not, because acute hepatitis B does not require therapy, while exacerbation of chronic hepatitis may benefit from it. Clinical and routine laboratory findings cannot help distinguishing between these two conditions. Therefore, several assays have been proposed for this purpose during the last few years. The presence of high levels of anti-HBe antibodies, HBsAg and HBV DNA are typical of chronic disease, whereas high titers of IgM anti-HBc, together with their high avidity index, characterize acute HBV infection. StarLing from the description of a patient with acute hepatitis B-who recently came to our observation-we critically review the currentlyavailable assays that may help distinguishing between the different conditions and lead to the optimal management of each patient.

    Acute liver failure can be the consequence of various etiologies, with most cases arising from drug-induced hepatotoxicity in Western countries. Despite advances in this field, the management of acute liver failure continues to be one of the most challenging problems in clinical medicine. The availability of adequate experimental models is of crucial importance to provide a better understanding of this condition and to allow identification of novel drug targets, testing the efficacy of new therapeutic interventions and acting as models for assessing mechanisms of toxicity. Experimental models of hepatotoxicity related to acute liver failure rely on surgical procedures, chemical exposure or viral infection. Each of these models has a number of strengths and weaknesses. This paper specifically reviews commonly used chemical in vivo and in vitro models of hepatotoxicity associated with acute liver failure. PMID:26631581

    Although plasma cell infiltration is not rare in autopsy of patients with multiple myeloma (MM), it is very rarely detected in living patients. This is because MM rarely causes significant liver dysfunction that requires further evaluation. A 49-year-old man presented with acute renal failure and was diagnosed with kappa light chain MM stage ?B. Thalidomide and dexamethasone were initiated. The patient developed a continuous increase in bilirubin that led to severe cholestasis. A liver biopsy revealed plasma cell infiltration. He then rapidly progressed to liver failure and died. Treatment options are limited in MM with significant liver dysfunction.Despite new drug therapies in MM, those patients with rapidly progressive liver failure appear to have a dismal outcome.

    Hypoxic hepatitis (HH), also known as ischaemic hepatitis or shock liver, is an acute liver injury caused by hepatic hypoxia. Cardiac failure, respiratory failure and septic shock are the main underlying conditions. In each of these conditions, several haemodynamic mechanisms lead to hepatic...... hypoxia. A shock state is observed in only 50% of cases. Thus, shock liver and ischaemic hepatitis are misnomers. HH can be a diagnostic pitfall but the diagnosis can be established when three criteria are met. Prognosis is poor and prompt identification and treatment of the underlying conditions...

    AIM: To establish an appropriate primate model of fulminant hepatic failure (FHF). METHODS: We have, for the first time, established a large animal model of FHF in Macaca mulatta by intraperitoneal infusion of amatoxin and endotoxin. Clinical features, biochemical indexes, histopathology and iconography were examined to dynamically investigate the progress and outcome of the animal model. RESULTS: Our results showed that the enzymes and serum bilirubin were markedly increased and the enzyme-bilirubin segregation emerged 36 h after toxin administration. Coagulation activity was significantly decreased. Gradually deteriorated parenchymal abnormality was detected by magnetic resonance imaging (MRI) and ultrasonography at 48 h. The liver biopsy showed marked hepatocyte steatosis and massive parenchymal necrosis at 36 h and 49 h, respectively. The autopsy showed typical yellow atrophy of the liver. Hepatic encephalopathy of the models was also confirmed by hepatic coma, MRI and pathological changes of cerebral edema. The lethal effects of the extrahepatic organ dysfunction were ruled out by their biochemical indices, imaging and histopathology. CONCLUSION: We have established an appropriate large primate model of FHF, which is closely similar to clinic cases, and can be used for investigation of the mechanism of FHF and for evaluation of potential medical therapies.

    Full Text Available A 40 year old woman presented with a short history of acute onset of breathlessness to the ER of our hospital and after initial evaluation for acute pulmonary embolism which was ruled out after carrying out the appropriate investigations, she was diagnosed to be afflicted with syringomyelia based on her neurological symptoms and clinical findings, which was confirmed by doing an MRI scan, which was her basic diagnosis that was complicated by acute hypercapnic respiratory failure. This case is being reported to highlight syringomyelia as an unusual cause of acute respiratory failure, which manifested clinically in this patient as its first presentation and the underlying neurological diagnosis has been found to be present in very few reported cases (less than 0.01% of case reports in the available literature as the basic disease in the absence of its classical presenting features. Problems associated with acute respiratory failure in the setting of syringomyelia are discussed.

    Full Text Available The mechanisms of protein quality control in hepatocytes in cases of alcoholic hepatitis (AH including ufmylation, FAT10ylation, metacaspase 1 (Mca1, ERAD (endoplasmic reticulum-associated degradation, JUNQ (juxta nuclear quality control, IPOD (insoluble protein deposit autophagocytosis, and ER stress are reviewed. The Mallory–Denk body (MDB formation develops in the hepatocytes in alcoholic hepatitis as a consequence of the failure of these protein quality control mechanisms to remove misfolded and damaged proteins and to prevent MDB aggresome formation within the cytoplasm of hepatocytes. The proteins involved in the quality control pathways are identified, quantitated, and visualized by immunofluorescent antibody staining of liver biopsies from patients with AH. Quantification of the proteins are achieved by measuring the fluorescent intensity using a morphometric system. Ufmylation and FAT10ylation pathways were downregulated, Mca1 pathways were upregulated, autophagocytosis was upregulated, and ER stress PERK (protein kinase RNA-like endoplasmic reticulum kinase and CHOP (CCAAT/enhancer-binding protein homologous protein mechanisms were upregulated. In conclusion: Despite the upregulation of several pathways of protein quality control, aggresomes (MDBs still formed in the hepatocytes in AH. The pathogenesis of AH is due to the failure of protein quality control, which causes balloon-cell change with MDB formation and ER stress.

    Acute liver failure is a rare but potentially devastating disease. Throughout the last few decades, acute liver failure outcomes have been improving in the context of the optimized overall management. This positive trend has been associated with the earlier recognition of this condition, the improvement of the intensive care unit management, and the developments in emergent liver transplantation. Accordingly, we aimed to review the current diagnostic and therapeutic approach to this syndrome, especially in the intensive care unit setting.

    In this case report, a young woman had acute viral hepatitis (HAV) and acute pancreatitis together. She was admitted to our hospital with fever, jaundice and abdominal pain. Hepatic and pancreatic enzymes were elevated. Her serum alanine aminotransferase (ALT) level was high. An initial abdominal ultrasound was per-formed at hospital and revealed features of acute viral hepatitis. Spiral computed imaging revealed imaging features of an acute stage of pancreatitis and gallbladder wall thickness. HAV infection was diagnosed by the detection of immunoglobulin M (IgM) against HAV in the serum. She was closely monitored and treated conservatively. On 10th day of hospital admission she was discharge after an uneventful recovery. In the current literature HAV infections have rarely been reported as a cause of acute pancreatitis.

    157 acute viral hepatitis and 60 chronic active ones have been analyzed focusing on NANB etiology. HAV was implicated in 36.3% of the hole acute viral hepatitis sample, HBV in 29.3%, and HNANBV was presumed as etiology in 31.2%, 5 patients (3.2%) had acute infection by HAV, on previous one by HBV, except for Epstein-Barr virus, no other test for viruses were determined (CMV, HSV, etc.). Male/female ratio was 1.4:1, 1.9:1, and 1.4:1 for HAV, HBV and HNANBV acute hepatitis respectively; HAV was the main etiology in the 0-9 age group (72.2%) although it only represents 11.5% of the sample; small occurrence of HAV hepatitis were found in patients over 40 (8.8%); HBV was clearly prevalent in patients over 50 (65.2%); the highest concentration of NANB etiology was found between 20-39 years old, but it was represented in all age-groups. Out of 49 NANB acute hepatitis, 12.2% had related transfusional antecedents, 12.2% belonged to health care worker group, and 4.1% had a close family NANB hepatitis contact; 71.5% had no reported antecedent. Viral source was presumably implicated in 75.0% of chronic active hepatitis, 25.0% attributable to HNANBV. Results seem not feasible to transfer to general population due to the facts that most patients were of specialized consult, and pediatric assistance is unusual to the authors practice.

    Acute renal failure (ARF) is a serious medical complication during pregnancy, and, in the post-partum period, is associated with significant maternal morbidity and mortality as well as fetal loss. The objective of our study is to find the etiology and maternal outcome of ARF during pregnancy. The study was conducted at the Obstetrics and Gynecology Department of the Institute of Kidney Disease and Research Center, Ahmedabad, India from January 2009 to January 2011. Fifty previously healthy patients who developed ARF, diagnosed on oliguria and serum creatinine >2 mg%, were included in the study. Patients with a known history of renal disease, diabetes and hypertension were excluded from the study. All patients were followed-up for a period of six months. Patient re-cords, demographic data, urine output on admission and preceding history of antepartum hemorrhage (APH), post-partum hemorrhage (PPH), septicemia, operative interventions and retained product of conception were noted and need for dialysis was considered. Patients were thoroughly examined and baseline biochemical investigations and renal and obstetrical ultrasound were performed on each patient and bacterial culture sensitivity on blood, urine or vaginal swabs were performed in selected patients. The age range was 19-38 years (mean 26 ± 3.8). The first trimester, second trimester and puerperal groups comprised of four (8%), 25 (50%) and 21 patients (42%), respectively. Hemorrhage was the etiology for ARF in 15 (30%), APH in ten (20%) and PPH in five (10%) patients. Eleven (22%) patients had lower segment cesarian section (LSCS) while 36 (78%) patients had normal vaginal delivery. In 20 (40%) patients, puerperal sepsis was the etiological factor, while pre-eclampsia, eclampsia and HELLP syndrome accounted for 18 (36%) patients. Two (4%) patients had disseminated intravascular coagulation on presentation while one (2%) patient was diagnosed with hemolytic uremic syndrome. Maternal mortality was 12% (n = 6

    Prompt treatment in tumor-associated encephalopathy may prolong survival. We describe a 69-year-old male patient who was presented with fulminant hepatic failure, secondary to small-cell lung carcinoma with rapidly progressing encephalopathy. Both symptoms remitted following chemotherapy, suggesting swift diagnosis and administration of chemotherapy to be effective in treatment of fulminant hepatic failure and encephalopathy.

    Full Text Available Context: There is a need for identifying risk factors aggravating development of acute renal failure after attaining trauma and defining new parameters for better assessment and management. Aim of the study was to determine the incidence of acute renal failure among trauma patients, and its correlation with various laboratory and clinical parameters recorded at the time of admission and in-hospital mortality. Subjects and Methods: The retrospective cohort study included admitted 208 trauma patients over a period of one year. 135 trauma patients at the serum creatinine level >2.0 mg/dL were enrolled in under the group of acute renal failure. 73 patients who had normal creatinine level made the control group. They were further assessed with clinical details and laboratory investigations. Results: Incidence of acute renal failure was 3.1%. There were 118 (87.4% males and average length of stay was 9 (1, 83 days. Severity of injury (ISS, GCS was relatively more among the renal failure group. Renal failure was transient in 35 (25.9% patients. They had higher incidence of bone fracture (54.0% (P = 0.04. Statistically significant association was observed between patients with head trauma and mortality 72 (59.0% (P = 0.001. Prevalence of septic 24 (59.7% and hemorrhagic 9 (7.4% shock affected the renal failure group. Conclusion: Trauma patients at the urea level >50 mg/dL, ISS >24 on the first day of admission had 23 times and 7 times the risk of developing renal failure. Similarly, patients with hepatic dysfunction and pulmonary dysfunction were 12 times and 6 times. Patients who developed cardiovascular dysfunction, hematological dysfunction and post-trauma renal failure during the hospital stay had risk for mortality 29, 7 and 8 times, respectively. The final prognostic score obtained was: 14FNx01hepatic dysfunction + 11FNx01cISS + 18FNx01cUrea + 12FNx01cGlucose + 10FNx01pulmonary dysfunction. Optimal score cut-off for prediction of renal failure was

    Full Text Available Abstract Background Hornet stings are generally associated with local and occasionally anaphylactic reactions. Rarely systemic complications like acute renal failure can occur following multiple stings. Renal failure is usually due to development of acute tubular necrosis as a result of intravascular haemolysis, rhabdomyolysis or shock. Rarely it can be following development of acute tubulo-interstitial nephritis. Case presentation We describe a young male, who was stung on face, head, shoulders and upper limbs by multiple hornets (Vespa orientalis. He developed acute renal failure as a result of acute tubulo-interstitial nephritis and responded to steroids. Conclusion Rare causes of acute renal failure like tubulo-interstitial nephritis should be considered in a patient with persistent oliguria and azotemia following multiple hornet stings. Renal biopsy should be undertaken early, as institution of steroid therapy may help in recovery of renal function

    Hepatic retransplant constitutes 10-20% of all orthotopic hepatic transplants. The piggy-back technique was used in hepatectomy with conservation of the retrohepatic vena cava. A side-to-side cavo-cavostomy technique is described in the case of hepatic congestion or acute Budd Chiari syndrome post-transplant. This is an extremely serious condition and can result in death. We present the first case of hepatic retransplant performed in Hospital Hermanos Ameijeiras in a patient who received who received his first transplant due to non-resectable hepatocarcinoma and who required retransplant due to acute rejection and graft dysfunction. During retransplant, the Belghiti side-to-side anastomosis technique was used to resolve the acute Budd Chiari syndrome that presented itself. Post-surgical evolution at 18 months was satisfactory without evidence of complications of the graft. Acute Budd Chiari syndrome post-transplant can satisfactorily be resolved with the Belghiti technique, although it is preferable to take prophylactic measures to avoid it.

    Full Text Available Hepatomegaly, decrease in the liver paranchymal echo and increase in the gallbladder wall thickness has been shown in acute viral hepatitis. The present study was done to determine sonographic changes in acute viral hepatitis. We performed liver and bile ducts sonography and specific tests on 42 patients (mean age: 31.5 and 61% male with acute viral hepatitis. Gallbladder wall thickness was seen in 45.2% and hepatomegaly in 33.3% of patients and liver paranchymal echo was decreased in 19.3%. Age, sex, type of hepatitis, cholecystitis like symptoms, aspartate aminotransfrase, alanine aminotransfrase, alkaline phosphatase and bilirubin did not significantly corralate with these changes. Only raised prothrombin time was strongly correlated to the thickening of the gallbladder and decrease in the liver paranchymal echo and cholesistic like symptoms we can postulate that thickening of the gallbladder and decrease in the liver paranchymal echo is not dependent on the severity and speed of the paranchymal necrosis (as considered with ALT and AST but they depend on the liver function disturbance (as considered with PT because the thickening of the gall bladder is present in 45% of the patients and 10% of the normal population have gallbladder stones, one should not perform the diagnosis of acute cholecystitis, only on the basis of sonographic report without attention to the clinical and laboratory data.

  12. Acute renal failure and severe thrombocytopenia associated with metamizole

    Directory of Open Access Journals (Sweden)

    Maria Dolores Redondo-Pachon

    2014-01-01

    Full Text Available Metamizole or dipyrone is a pyrazolone derivative that belongs to the non-steroidal anti-inflammatory drugs. Its main side-effect is hematological toxicity. Thrombocytopenia due to metamizole is rare and is usually associated with the involvement of the two other blood series. Drug-induced thrombocytopenia is more frequently related to immune mechanisms, and the diag-nosis is still largely made by exclusion of other causes and by correlation of timing of thrombocytopenia with the administration of drug. Metamizole may cause acute renal failure due to hemodynamic renal failure/acute tubular necrosis and/or acute tubulointerstitial nephritis. We report a case of acute renal failure and severe thrombocytopenia after metamizole. As far as we know, this combination of adverse effects from this drug has not been reported previously.

    2014-10-01

    Full Text Available Renal failure is the loss of renal function, either acute or chronic, that results in azotemia and syndrome of uremia. Acute renal failure, is also known as acute kidney injury (AKI, is defined as an abrupt (within 48 hours reduction in kidney function. The initial management of acute kidney failure involves treating the underlying cause, stopping nephrotoxic drugs and ensuring that the patient is euvolaemic with an adequate mean arterial blood pressure. However, no specific treatments have been shown to reverse the course AKF so Renal Replacement Therapy (RRT is the cornerstone of further management. RRT therapy can be administrated either intermittently or continuously. Multiple modalities of RRT are currently available. The purpose of this review is to familiarize different modalities of RRT for blood purification.

    A 73-year-old woman was admitted to hospital because of progressive dyspnea on exertion. Computed tomography revealed a large hepatic tumor, which was proved to be a hepatic epithelioid hemangioendothelioma (EHE). Echocardiography demonstrated high cardiac output, for which the tumor was considered to be the leading cause. A transcatheter arterial chemoembolization (TACE) was performed sequentially at 1-month intervals to reduce the size of the hepatic tumor, and this temporarily improved the patient's cardiac condition and quality of life. In this case, we successfully used TACE in the treatment of hepatic EHE with high-output heart failure. TACE is a reasonable choice of treatment both for managing malignant hepatic tumors and resolving low systemic vascular resistance by embolization of the abnormal neoangiogenic vessels. Nevertheless, clinicians should be aware of the potential adverse effect of hepatic decompensation induced by TACE, especially when the tumor involvement is widespread and poorly preserved hepatic function is encountered.

    Acute liver failure in neonates is rare and is frequently associated with an unfavourable outcome. There is no curative treatment other than liver transplantation. Screening for viral, metabolic, toxic or vascular disease is essential to assess the prognosis and to guide specific treatment. Hepatic haemorrhage in neonates is often associated with bacterial infection, trauma and coagulopathies. We present a unique case of neonatal acute liver failure and multifocal massive haemorrhagic intrahepatic lesions of traumatic origin, documented by US and MRI. The patient made a spontaneous recovery. Clinical, biological and imaging outcome was excellent despite the apparent severity of the initial features. The only possible aetiology was a difficult caesarean delivery for mild fetal macrosomia. (orig.)

    BACKGROUND:Fulminant hepatic failure (FHF) is not uncommon in our clinical practice in Bangladesh. There was a rise in acute hepatitis E virus (HEV) in Bangladesh after the 2004 lfoods. At that time, most of the country was under water for more than a month, leading to sewage contamination of the water supply. The aim of this study was to investigate the etiology of FHF in Bangladesh. METHODS: In this retrospective study, 23 patients with FHF who presented with severe impairment of hepato-cellular function (i.e. encephalopathy, coagulopathy and jaundice) within 6 months of onset of symptoms were included. There were 17 men and 6 women, aged from 18 to 32 years. Four of the women were pregnant. Patients were tested for markers for common hepatotrophic viruses. A relevant history was taken and the Patient Record Book of the Unit was reviewed. RESULTS: 56.52% patients (13/23) had HEV infection, and all were anti-HEV IgM-positive tested by ELISA. HBV infection was detected in 34.78% patients (8/23), all of whom were tested positive for either HBsAg or anti-HBs IgM by ELISA. 8.7%patients (2/23) had a positive history for intake of alcohol and/or drugs. CONCLUSIONS:Acute HEV infection is the leading cause of FHF in Bangladesh. Sewage contamination of the water supply following lfoods contributes to a higher incidence of HEV infection. HBV infection is also important.

    Objective: To understand the characteristics of acute hepatitis B inpatients reported by the hepatitis B surveillance pilot points and to estimate the consistency between the diagnosed and reported types of hepatitis B by the clinicians involved. Methods: Data related to acute hepatitis B was from the NNDRS and the characteristics of acute hepatitis B were classified by querying Hospital Information System. We recorded the results based on clinical diagnosis and analyzed the consistency between the reported and diagnosed types that the clinicians made, on hepatitis B. Results: A total of 179 patients were included in this study with all of them as acute hepatitis B reported through NNDRS in 2015-2016. In terms of the durations of disease, among the 179 cases who were HBsAg positive, 32.40% (58/179) of them exceeding 6 months, 2.79% (5/179) within 6 months and 64.80% (116/179) tested the first time or never. Among the 179 cases who claimed having the history of hepatitis, 33.52% (60/179) of them identified as having hepatitis B, 1.12% (2/179) were hepatitis A, C or E, 41.34% (74/179) did not have the signs on hepatitis, while the rest 24.02% (43/179) did not know the situation. Only 79.89% (143/179) of the patients showed the symptoms or signs of hepatitis, but the rest 20.11% (36/179) did not. Among the 179 reported acute hepatitis patients, 67 of them were diagnosed as acute hepatitis B while 112 cases were as non-acute hepatitis B. The consistent rate of acute hepatitis B was 37.43% (67/179). Among the 112 cases that were diagnosed as non-acute hepatitis B, proportions of chronic hepatitis B and cirrhosis were 49.11%(55/112) and 16.07%(18/112) respectively. Conclusion: Consistency between the reported type of acute hepatitis B inpatients and the types diagnosed by clinicians was poor. Our results suggested that clinicians should make the accurate diagnosis at first place and then report to the Network in accordance with the clinical diagnosis classification

    Acute lymphoblastic leukemia (ALL) in adults is a relatively rare malignancy. The typical presentation includes signs and symptoms associated with bone marrow failure, including fevers, infections, fatigue, and excessive bruising. In this article, we report an unusual systemic presentation of ALL in a previously healthy 18-year-old man. He initially presented with several-day history of nausea and vomiting, 10-pound weight loss, and right upper quadrant abdominal pain with evidence of acute hepatocellular liver injury (elevations in aspartate aminotransferase/alanine aminotransferase) and elevation in serum creatinine. Further history revealed that he just joined the Marine Corp; in preparation, he had been lifting weights and taking protein and creatine supplements. A complete serological evaluation for liver disease was negative and creatine phosphokinase was normal. His aspartate aminotransferase and alanine aminotransferase declined, and he was discharged with expected improvement. However, he returned one week later with continued symptoms and greater elevation of aminotransferases. Liver biopsy was nondiagnostic, revealing scattered portal and lobular inflammatory cells (primarily lymphocytes) felt to be consistent with drug-induced liver injury or viral hepatitis. Given his elevated creatinine, unresponsive to aggressive volume expansion, a kidney biopsy was performed, revealing normal histology. He subsequently developed an extensive left lower extremity deep venous thrombosis. Given his deep venous thrombosis, his peripheral blood was sent for flow cytometry, which revealed lymphoblasts. Bone marrow biopsy revealed 78% blasts with markers consistent with acute B-cell lymphoblastic leukemia. This report emphasizes that right upper quadrant abdominal pain with liver test abnormalities may be the initial presentation of a systemic illness such as ALL.

    The number of patients developing liver failure; acute on chronic liver failure and acute liver failure continues to increase, along with the demand for donor livers for transplantation. As such there is a clinical need to develop effective extracorporeal devices to support patients with acute liver failure or acute-on-chronic liver failure to allow time for hepatocyte regeneration, and so avoiding the need for liver transplantation, or to bridge the patient to liver transplantation, and also potentially to provide symptomatic relief for patients with cirrhosis not suitable for transplantation. Currently devices can be divided into those designed to remove toxins, including plasma exchange, high permeability dialyzers and adsorption columns or membranes, coupled with replacement of plasma proteins; albumin dialysis systems; and bioartificial devices which may provide some of the biological functions of the liver. In the future we expect combinations of these devices in clinical practice, due to the developments in bioartificial scaffolds.

    Full Text Available Previous retrospective study (1992 to 2000 performed in Spain showed that drug toxicity, viral hepatitis, and indeterminate etiology were the most prevalent causes of acute liver failure (ALF. In the last decade, there is no information about ALF in our country. For these reasons we analyze retrospectively, in a ten-year period (2000 to 2010, the presumed causes, clinical characteristics, course, and outcome of ALF in a Spanish community. Causes of ALF were indeterminate in 4 patients (24%, acute hepatitis B infection in 4 patients (24%, drug or toxic reactions in 4 patients (24%, including one case of acetaminophen overdose, followed by miscellaneous causes. The overall short-term survival (6 weeks after admission was 65%. Liver transplantation was performed in 11 patients with a survival of 82%. Despite fulfilling criteria, 2 patients were not transplanted because of contraindications; they both died. In summary, acute hepatitis B and indeterminate cause are still being the most frequent causes of ALF in our region, and patients with ALF have an excellent chance of survival after emergency liver transplantation. Acetaminophen overdose still represents a very rare cause of ALF in our community.

    Butachlor is a highly effective herbicidal substance widely used by farmers. We report a 60-year-old man with exfoliative dermatitis, jaundice, increase in liver enzymes and eosinophilia one day after accidental dermal exposure to butachlor toxin. The diagnostic workup showed no other cause and liver histology was consistent with substance-induced toxic hepatitis. Within two weeks of conservative therapy, his liver function tests returned to normal.

    In Wilson disease (WD), functional loss of ATPase copper-transporting β (ATP7B) impairs biliary copper excretion, leading to excessive copper accumulation in the liver and fulminant hepatitis. Current US Food and Drug Administration– and European Medicines Agency–approved pharmacological treatments usually fail to restore copper homeostasis in patients with WD who have progressed to acute liver failure, leaving liver transplantation as the only viable treatment option. Here, we investigated the therapeutic utility of methanobactin (MB), a peptide produced by Methylosinus trichosporium OB3b, which has an exceptionally high affinity for copper. We demonstrated that ATP7B-deficient rats recapitulate WD-associated phenotypes, including hepatic copper accumulation, liver damage, and mitochondrial impairment. Short-term treatment of these rats with MB efficiently reversed mitochondrial impairment and liver damage in the acute stages of liver copper accumulation compared with that seen in untreated ATP7B-deficient rats. This beneficial effect was associated with depletion of copper from hepatocyte mitochondria. Moreover, MB treatment prevented hepatocyte death, subsequent liver failure, and death in the rodent model. These results suggest that MB has potential as a therapeutic agent for the treatment of acute WD. PMID:27322060

    Full Text Available Dengue fever is the world's most important viral hemorrhagic fever disease, the most geographically wide-spread of the arthropod-born viruses, and it causes a wide clinical spectrum of disease. We report a case of dengue hemorrhagic fever complicated by acute hepatitis. The initial picture of classical dengue fever was followed by painful liver enlargement, vomiting, hematemesis, epistaxis and diarrhea. Severe liver injury was detected by laboratory investigation, according to a syndromic surveillance protocol, expressed in a self-limiting pattern and the patient had a complete recovery. The serological tests for hepatitis and yellow fever viruses were negative. MAC-ELISA for dengue was positive.

    Full Text Available We report a case of a 4-months infant with fever in the absence of other specific symptoms that has rapidly and unexpectedly developed acute liver failure (ALF with coagulopathy and complicated with bone marrow failure without encephalopathy. The main viral infection agents (hepatitis virus A, B, C, Citomegalovirus, Ebstain Barr virus, Parvovirus B19, Adenovirus, drug-induced hepatotoxicity and metabolic disorders associated to ALF were excluded. Quantitative determination of Human Herpesvirus 6 (HHV6 genome was positive with a significant number of copies for mL. A favorable evolution of the clinical symptoms and a progressive hematochemical resolution were obtained. Plasma and Vitamin K were administrated as a support therapy for treating coagulopathy. The present case report and the cases’ review from the literature, evidence the importance of always including screening for HHV6 infection in the diagnostic approach to acute onset of liver failure. HHV6 is a common virus in the pediatric population with a greater number of cases of fulminant viral non-A, non-B, non-C hepatitis in immunocompetent patients due to this virus: these forms have often a high mortality rate and maybe necessitate liver transplantation; for this reason correct etiological agent identification is mandatory for the prognosis and it has to be based on the quantitative search of the virus’s genome. Pathogenesis of liver-induced damage associated to HHV6 remains unclear; however in vitro studies demonstrate the potential hepatotoxicity effects of this virus.

    Dianne E. Grunes

    2012-01-01

    Full Text Available We report a case of fulminant liver failure resulting in emergent liver transplantation following 3 weeks of nausea, vomiting, and malaise from Jamaican Vomiting Sickness. Jamaican Vomiting Sickness is caused by ingestion of the unripe arils of the Ackee fruit, its seeds and husks. It is characterized by acute gastrointestinal illness and hypoglycemia. In severe cases, central nervous system depression can occur. In previous studies, histologic sections taken from patients with Jamaican Vomiting Sickness have shown hepatotoxicity similar to that seen in Reye syndrome and/or acetaminophen toxicity. We highlight macroscopic and microscopic changes in the liver secondary to hepatoxicity of Ackee fruit versus those caused by a previously unknown sickle cell trait. We discuss the clinical variables and the synergistic hepatotoxic effect of Ackee fruit and ischemic injury from sickled red blood cells, causing massive hepatic necrosis in this patient.

    2005-01-01

    We report on a 26-year-old man who presented with severe jaundice and elevated serum liver enzyme activities after having received a dose of Twinrix(○R). In his past medical history, jaundice or abnormal liver function tests were never recorded. Following admission, an elevated immunoglobulin G level and antinuclear antibodies at a titer of 320 with a homogenous pattern were found. Histology of a liver biopsy showed marked bridging liver fibrosis and a chronic inflammation, compatible with autoimmune hepatitis. Treatment was started with budesonide and ursodeoxycholic acid,and led to complete normalization of the pathological liver function tests. We believe that Twinrix(○R) led to an acute exacerbation of an unrecognized autoimmune hepatitis in our patient. The pathogenesis remains to be clarified. It is tempting to speculate that inactivated hepatitis A virus and/or recombinant surface antigen of the hepatitis B virus -as seen in patients with chronic hepatitis C and unrecognized autoimmune hepatitis who were treated with interferon alpha-might have been responsible for disease exacerbation.

  8. Hepatitis E virus as a Cause of Acute Hepatitis in The Netherlands.

    Directory of Open Access Journals (Sweden)

    Aletta T R Tholen

    Full Text Available Recent studies indicate that 27% of Dutch blood donors have evidence of past infection with HEV. However, the low number of diagnosed HEV infections indicates either an asymptomatic course or under diagnosis.We investigated whether HEV is a cause of acute hepatitis in Dutch patients and which diagnostic modality (serology or PCR should be used for optimal detection.Serum samples were retrospectively selected from non-severely immuno-compromised patients from a university hospital population, suspected of having an infectious hepatitis. Criteria were: elevated alanine aminotransferase (ALT> 34 U/l and request for antibody testing for CMV, EBV or Hepatitis A (HAV.All samples were tested for HEV using ELISA and PCR. Ninety patients/sera were tested, of which 22% were HEV IgG positive. Only one serum was IgM positive. HEV PCR was positive in two patients: one patient was both HEV IgM and IgG positive, the other patient was only IgG positive. Both HEV RNA positive samples belonged to genotype 3. Evidence of recent infection with CMV, EBV and HAV was found in 13%, 10% and 3% respectively.Although our study is limited by small numbers, we conclude that HEV is a cause of acute hepatitis in hospital associated patients in The Netherlands. Moreover, in our study population the prevalence of acute HAV (3% was almost similar to acute HEV (2%. We propose to incorporate HEV testing in panels for acute infectious hepatitis. Negative results obtained for HEV IgM in a HEV PCR positive patient, indicates that antibody testing alone may not be sufficient and argues for PCR as a primary diagnostic tool in hospital associated patients. The high percentage of HEV IgG seropositivity confirms earlier epidemiological studies.

In Iran, it seems that HCV prevalence in general population is less than one percent, which is much lower than in most of the regional countries(1. However, the infection is emerging in Iran mostly due to problem of intravenous drug abuse and needle-sharing in the country (2, 3. The patients receiving maintenance transfusion such as chronic renal failure (CRF patients and the patients with thalassemia major are the other population who are at the high risk of HCV acquisition although compulsory blood screening has been able to remarkably decrease the HCV incidence in these patients (4. The prevalence of HCV infection among CRF patients on hemodialysis in Tehran, the capital of Iran, was around 13 percent in 2002 (5. There is no valid data regarding HCV incidence rate among CRF patients in country. However, according to the most recent official report of Management of Special Diseases and Transplantation Center (MSDT, the prevalence of HCV infection among patients on hemodialysis in the whole country has decreased from 14.4% in 1999 to 4.5% in 2005. Various reasons might be responsible for this reduction such as blood screening; developing technology of alternative modalities instead of transfusion in Iran like producing domestic Erythropoietin which has been resulted in decreasing transfusion; early transplantation; and training health staffs. On the other hand, the other reason such as mortality ofHCV infected CRF patients should not be neglected. Although there is no data in this regard in Iran, a meta-analysis, demonstrated that HCV infected patients on dialysis have an increased risk of mortality compared to HCV negative cases (6. Therefore, with the lack of data defining incidence rate in Iran, the reduction of HCV prevalence in the country should not overlook the necessity of designing a comprehensive strategy to control HCV

    We report the first case of acute renal failure with hyperkalemia associated with the recently marketed direct renin inhibitor aliskiren. To optimize blood pressure control, the antihypertensive medication of a 76-year-old hypertensive female patient was changed from the angiotensin II receptor antagonist irbesartan to aliskiren. Spironolactone was continued, as serum creatinine and potassium levels were initially normal. Two weeks later the patient presented with acute oliguric renal failure, symptomatic hyperkalemia and metabolic acidosis, necessitating emergency dialytic treatment. Unrecognized pre-existing renal insufficiency (CKD Stage 2 - 3) and the continuation of spironolactone were identified as predisposing risk factors.

    Acute renal failure (ARF), which is diagnosed in 3.4-20% of newborns, is polyetiological in most cases. We present a newborn with non-oliguric ARF diagnosed in the first day of life, and caused by asphixia, intrauterine infection (IUI) and nephrotoxic effects of metotrexate treatment during pregnancy. Antibiotics, including netilmicin and vankomycin, were given because of IUI and infected central venous catheter. Dosage of drugs was adjusted to renal failure parameters, but monitoring of their serum levels was not available. It could cause augmented acute tubular necrosis and interstitial nephritis. Analysis of ARF risk factors in newborns helps in early diagnosis of renal damage and in prompt implementation of therapy.

    As the population of elderly people is increasing, the number of patients requiring hospitalization for acute exacerbations is rising. Traditionally, these episodes of hemodynamic instability were viewed as a transient event characterized by systolic dysfunction, low cardiac output, and fluid overload. Diuretics, along with vasodilator and inotropic therapy, eventually became elements of standard care. In a multicenter observational registry (ADHERE--Acute Decompensated Heart Failure National Registry) of more than 275 hospitals, patients with acute decompensated heart failure were analyzed for their characteristics and treatments options. These data have shown that this population consists of multiple types of heart failure, various forms of acute decompensation, combinations of comorbidities, and varying degrees of disease severity. The challenges in the treatment require multidisciplinary approaches since patients typically are elderly and have complex combinations of comorbidities. So far only a limited number of drugs is currently available to treat the different groups. Over the past years it was shown that even "standard drugs" might be deleterious by induction of myocardial injury, worsening of renal function or increasing mortality upon treatment. Therefore, based on pathophysiology, different types of acute decompensated heart failure require specialized treatment strategies.

    AIM: Clostridium difficile infection is primarily a nosocomial infection but asymptomatic carriers of Clostridium difficile can be found in up to 5% of the general population.Ampicillin, cephalosporins and clindamycin are the antibiotics that are most frequently associated with Clostridium difficile-associated diarrhea or colitis. Little is known about acute renal failure as a consequence of Clostridium difficile-associated diarrhea.METHODS: In this case report, we describe the course of Clostridium difficile-associated diarrhea in an 82-yearold patient developing acute renal failure. Stopping the offending agent and symptomatic therapy brought a rapid improvement of diarrhea and acute renal failure, full recovery was gained 18 d after admission. In a systematic review we looked for links between the two conditions.RESULTS: The link between Clostridium difficilr-associated diarrhea and acute renal failure in our patient was most likely volume depletion. However, in experimental studies a direct influence of Clostridium difficile toxins on renal duct cells could be shown.CONCLUSION: Rapid diagnosis, nonspecific supportive treatment and specific antibiotic treatment, especially in the elderly, may lower excess mortality Clostridium difficile-associated diarrhea and renal failure being possible complications.

  14. High flow nasal oxygen in acute respiratory failure.

    Ricard, J-D

    2012-07-01

    Use of high flow nasal cannula oxygen (HFNC) is increasingly popular in adult ICUs for patients with acute hypoxemic respiratory failure. This is the result of the successful long-term use of HFNC in the neonatal field and recent clinical data in adults indicating beneficial effects of HFNC over conventional facemask oxygen therapy. HFNC rapidly alleviates symptoms of respiratory distress and improves oxygenation by several mechanisms, including deadspace washout, reduction in oxygen dilution and in inspiratory nasopharyngeal resistance, a moderate positive airway pressure effect that may generate alveolar recruitment and an overall greater tolerance and comfort with the interface and the heated and humidified inspired gases. Indications of HFNC are broad, encompassing most if not all causes of acute hypoxemic respiratory failure. HFNC can also provide oxygen during invasive procedures, and be used to prevent or treat post-extubation respiratory failure. HFNC may also alleviate respiratory distress in patients at a palliative stage. Although observational studies suggest that HFNC might reduce the need for intubation in acute hypoxemic respiratory failure; such a reduction has not yet been demonstrated. Beyond this potential additional effect on outcome, the evidence already published argues in favor of the large use of HFNC as first line therapy for acute respiratory failure.

Yet, there is a paucity of randomized data on the management of patients with heart failure complicating acute coronary syndrome, as acute coronary syndrome and cardiogenic shock have frequently been...... defined as exclusion criteria in trials and registries. As a consequence, guideline recommendations are mostly driven by observational studies, even though these patients have a particularly poor prognosis compared to heart failure patients without signs of coronary artery disease. In acute heart failure......, and especially in cardiogenic shock related to ischemic conditions, vasopressors and inotropes are used. However, both pathophysiological considerations and available clinical data suggest that these treatments may have disadvantageous effects.

    2009-09-01

    Renal replacement therapy became a common clinical tool to treat patients with severe acute kidney injury (AKI) since the 1960s. During this time dialytic options have expanded considerably; biocompatible membranes, bicarbonate dialysate and dialysis machines with volumetric ultrafiltration control have improved the treatment for acute kidney injury. Along with advances in methods of intermittent hemodialysis, continuous renal replacement therapies have gained widespread acceptance in the treatment of dialysis-requiring AKI. However, many of the fundamental aspects of the renal replacement treatment such as indication, timing of dialytic intervention, and choice of dialysis modality are still controversial and may influence AKI patient's outcomes. This review outlines current concepts in the use of dialysis techniques for AKI and suggests an approach for selecting the optimal method of renal replacement therapy.

  17. Central respiratory failure during acute organophosphate poisoning.

    Carey, Jennifer L; Dunn, Courtney; Gaspari, Romolo J

    2013-11-01

    Organophosphate (OP) pesticide poisoning is a global health problem with over 250,000 deaths per year. OPs affect neuronal signaling through acetylcholine (Ach) neurotransmission via inhibition of acetylcholinesterase (AChE), leading to accumulation of Ach at the synaptic cleft and excessive stimulation at post-synaptic receptors. Mortality due to OP agents is attributed to respiratory dysfunction, including central apnea. Cholinergic circuits are integral to many aspects of the central control of respiration, however it is unclear which mechanisms predominate during acute OP intoxication. A more complete understanding of the cholinergic aspects of both respiratory control as well as neural modification of pulmonary function is needed to better understand OP-induced respiratory dysfunction. In this article, we review the physiologic mechanisms of acute OP exposure in the context of the known cholinergic contributions to the central control of respiration. We also discuss the potential central cholinergic contributions to the known peripheral physiologic effects of OP intoxication.

    Full Text Available Tumour Lysis syndrome (TLS is characterized by the massive destruction of tumoral cells and the release in the extracellular space of their content. While TLS may occur spontaneously before treatment, it usually develops shortly after the initiation of cytotoxic chemotherapy. These metabolites can overwhelm the homeostatic mechanisms and cause hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcemia. Moreover, TLS may lead to an acute renal failure (ARF. In addition to the hospital mortality induced by the acute renal failure itself, development of an ARF may preclude optimal cancer treatment. Therefore, prevention of the acute renal failure during acute tumor lysis syndrome is mandatory. The objective of this review is to describe pathophysiological mechanisms leading to acute tumor lysis syndrome, clinical and biological consequences of this syndrome and to provide up-to-date guidelines to ensure prevention and prompt management of this syndrome.

    Acute hepatitis due to hepatitis A virus is usually a benign selflimiting disease during childhood. Although many viral infections such as hepatitis B virus, Parvovirus, and Epstein-Barr virus are associated with extrahepatic autoimmune phenomena, such manifestations are rare in patients with acute hepatitis A infection. Immune thrombocytopenia is a benign, self-limiting disease in children, responding well to treatment and generally associated with viral infections. Immune thrombocytopenic purpura is rarely reported as a manifestation of acute hepatitis A. We report a five-year-old boy with immune thrombocytopenic purpura as the sole manifestation of anicteric acute hepatitis A infection. Acute hepatitis A should be included in the differential diagnosis of immune thrombocytopenic purpura.

    Full Text Available Abstract Background Combined iatrogenic vascular and biliary injury during cholecystectomy resulting in ischemic hepatic necrosis is a very rare cause of acute liver failure. We describe a patient who developed fulminant liver failure as a result of severe cholestasis and liver gangrene secondary to iatrogenic combine injury or the hepatic pedicle (i.e. hepatic artery, portal vein and bile duct during laparoscopic cholecystectomy. Case presentation A 40-years-old woman underwent laparoscopic cholecystectomy for acute cholecystitis. During laparoscopy, a severe bleeding at the liver hilum motivated the conversion to open surgery. Many sutures were placed across the parenchyma for bleeding control. After 48 hours, she rapidly deteriorated with encephalopathy, coagulopathy, persistent hypotension and progressive organ dysfunction including acute renal failure requiring hemodialysis and mechanical ventilation. An angiography documented an occlusion of right hepatic artery and right portal vein. In the clinical of acute liver failure secondary to liver gangrene, severe coagulopathy and progressive secondary multi-organ failure, the patient was included in the waiting list for liver transplantation. Two days later, the patient was successfully transplanted with initial adequate liver graft function. However, she developed bilateral pneumonia and severe gastrointestinal bleeding and finally died 24 days after transplantation due to bilateral necrotizing pneumonia. Conclusion The occurrence of acute liver failure due to portal triad injury during laparoscopic cholecystectomy is a catastrophic complication. Probably, the indication of liver transplantation as a life-saving strategy in patients with late diagnosis, acute liver failure, severe coagulopathy and progressive secondary multi-organ failure could be considered but only minimizing immunosuppressive regimen to avoid postoperative infections.

    The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normal however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure.

    Full Text Available Acute renal failure can cause neurologic manifestations such as mood swings, impaired concentration, tremor, stupor, coma, asterixis, dysarthria. Those findings can also be a sign of cerebral infarct. Here, we report a case of watershed cerebral infarction in a 70-year-old female patient with acute renal failure secondary to contrast administration and use of angiotensin converting enzyme inhibitor. Patient was evaluated with magnetic resonance imaging because of dysarthria. Magnetic resonance imaging revealed milimmetric acute ischemic lesion in the frontal and parietal deep white matter region of both cerebral hemisphere which clearly demonstrated watershed cerebral infarction affecting internal border zone. Her renal function returned to normal levels on fifth day of admission (BUN 32 mg/dl, creatinine 1.36 mg/dl and she was discharged. Dysarthria continued for 20 days.

    AIM:To evaluate the effect of intrahepatic transplantation of hepatic oval cells (HOC) on fulminant hepatic failure (FHF) in rats. METHODS:HOC obtained from rats were labeled wi th green fluocescent protein (GFP) or 5, 6- carboxyfluorescein diacetate succinmidyl ester (CFDASE). Cell fluorescence was observed under fluorescent microscope at 6, 24, 48 and 72 h after labeling. CFDASE labeled HOC (5 × 106 cells each rat) were injected into livers of rats with FHF induced by D-galactosamine. Serum albumin (ALB), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBil) levels were measured at different time points. Liver function of rats was examined on days 3, 7, 14 and 21 after HOC transplantation. RESULTS:The positive rate of GFP and CFDA-SE labeled HOC was 10% and 90%, respectively, with no significant change in cell viabilities. The survival rate was higher in HOC transplantation group than in control group, especially 48 (9/15 vs 6/15) and 72 h (9/15 vs 4/15) after HOC transplantation. The serum ALT, AST and TBil levels were decreased while the serum Alb level was increased after HOC transplantation. Fluorescence became faded and diffused in liver tissues, suggesting that proliferation and differentiation occur in transplanted HOC. CONCLUSION:CFDA-SE is superior to GFP in labeling HOC, although fluorescence intensity is decreased progressively with cell division. HOC transplantation can improve the liver function and increase the survival rate of recipients.

    AIM: To observe the adsorbent effect of resin on endotoxin,cytokine, bilirubin in plasma of patients with hepatic failure and to determine the resin perfusion as an artificial liver support system in the treatment of hepatic failure.METHODS: One thousand milliliters of discarded plasma was collected from each of 6 severe hepatitis patients treated with plasma exchange. The plasma was passed through a resin perfusion equipment for 1-2 h via extracorporeal circulation, and then absorbent indicators of transaminase,bilirubin, blood ammonia, endotoxin and cytokines were examined. In the meantime, study of in vivo resin plasma perfusion was performed on 7 severe hepatitis patients to compare the changes of endotoxin and cytokines in blood before and after perfusion.RESULTS: The levels of total bilirubin, endotoxin, interleukin 1β and TNF-α in plasma were significantly decreased after in vitro resin plasma perfusion. The levels of interleukin 1β,TNF-α and endotoxin in blood were also evidently declined after in vivo resin plasma perfusion. Nevertheless, no obvious changes in IL-6, creatinine (Cr) and urea nitrogen (UN), blood ammonia and electrolytes were found bothin vitroandin vivo.CONCLUSION: Bilirubin, endotoxin and cytokines in plasma of patients with hepatic failure can be effectively adsorbed by resinin vitro. Most cytokines and endotoxin in plasma can also be effectively removed by resinin vivo. It demonstrates that resin perfusion may have good treatment efficacy on hepatic failure and can be expected to slow down the progression of hepatic failure.

    AIM: To examine the serum from black African patients with acute hepatitis B to ascertain if integrants of viral DNA can be detected in fragments of cellular DNA leaking from damaged hepatocytes into the circulation.METHODS: DNA was extracted from the sera of five patients with uncomplicated acute hepatitis B and one with fulminant disease. Two subgenomic PCRs designed to amplify the complete genome of HBV were used and the resulting amplicons were cloned and sequenced.RESULTS: HBV and chromosomal DNA were amplified from the sera of all the patients. In one patient with uncomplicated disease, HBV DNA was integrated into host chromosome 7 q11.23 in the WBSCR1 gene. The viral DNA comprised 200 nucleotides covering the S and X genes in opposite orientation, with a 1 169 nudeotide deletion. The right virus/host junction was situated at nucleotide 1774 in the cohesive overlap region of the viral genome, at a preferred topoisomerase I cleavage motif. The chromosomal DNA was not rearranged.The patient made a full recovery and seroconverted to anti-HBs- and anti-HBe-positivity. Neither HBV nor chromosomal DNA could be amplified from his serum at that time.CONCLUSION: Integration of viral DNA into chromosomal DNA may occur rarely during acute hepatitis B and, with clonal propagation of the integrant, might play a role in hepatocarcinogenesis.

    Q fever which is caused by Coxiella burnetii, is a worldwide zoonosis. Many species of wild and domestic mammals, birds, and arthropods, are reservoirs of C.burnetii in nature, however farm animals are the most frequent sources of human infection. The most frequent way of transmission is by inhalation of contaminated aerosols. The clinical presentation of Q fever is polymorphic and nonspecific. Q fever may present as acute or chronic disease. In acute cases, the most common clinical syndromes are selflimited febrile illness, granulomatous hepatitis, and pneumonia, but it can also be asymptomatic. Fever with hepatitis associated with Q fever has rarely been described in the literature. Herein we report two cases of C.burnetii hepatitis presented with jaundice. In May 2011, two male cases, who inhabited in Malkara village of Tekirdag province (located at Trace region of Turkey), were admitted to the hospital with the complaints of persistent high grade fever, chills and sweats, icterus, disseminated myalgia and headache. Physical examination revealed fever, icterus and the patient appeared to be mildly ill but had no localizing signs of infection. Radiological findings of the patients were in normal limits. Laboratory findings revealed leukocytosis, increased hepatic and cholestatic enzyme levels, and moderate hyperbilirubinemia- mainly direct bilirubin, whereas serum C-reactive protein and erythrocyte sedimentation rate were found normal. Blood and urine cultures of the patients yielded no bacterial growth. Serological markers for acute viral hepatitis, citomegalovirus and Epstein-Barr virus infections, brucellosis, salmonellosis, toxoplasmosis and leptospirosis were found negative. Acute Q fever diagnosis of the cases were based on the positive results obtained by C.burnetii Phase II IgM and IgG ELISA (Vircell SL, Spain) test, and the serological diagnosis were confirmed by Phase I and II immunofluorescence (Vircell SL, Spain) method. Both cases were treated with

  18. Mesenchymal stem cell-derived molecules reverse fulminant hepatic failure.

    Directory of Open Access Journals (Sweden)

    Biju Parekkadan

    Full Text Available Modulation of the immune system may be a viable alternative in the treatment of fulminant hepatic failure (FHF and can potentially eliminate the need for donor hepatocytes for cellular therapies. Multipotent bone marrow-derived mesenchymal stem cells (MSCs have been shown to inhibit the function of various immune cells by undefined paracrine mediators in vitro. Yet, the therapeutic potential of MSC-derived molecules has not been tested in immunological conditions in vivo. Herein, we report that the administration of MSC-derived molecules in two clinically relevant forms-intravenous bolus of conditioned medium (MSC-CM or extracorporeal perfusion with a bioreactor containing MSCs (MSC-EB-can provide a significant survival benefit in rats undergoing FHF. We observed a cell mass-dependent reduction in mortality that was abolished at high cell numbers indicating a therapeutic window. Histopathological analysis of liver tissue after MSC-CM treatment showed dramatic reduction of panlobular leukocytic infiltrates, hepatocellular death and bile duct duplication. Furthermore, we demonstrate using computed tomography of adoptively transferred leukocytes that MSC-CM functionally diverts immune cells from the injured organ indicating that altered leukocyte migration by MSC-CM therapy may account for the absence of immune cells in liver tissue. Preliminary analysis of the MSC secretome using a protein array screen revealed a large fraction of chemotactic cytokines, or chemokines. When MSC-CM was fractionated based on heparin binding affinity, a known ligand for all chemokines, only the heparin-bound eluent reversed FHF indicating that the active components of MSC-CM reside in this fraction. These data provide the first experimental evidence of the medicinal use of MSC-derived molecules in the treatment of an inflammatory condition and support the role of chemokines and altered leukocyte migration as a novel therapeutic modality for FHF.

    Full Text Available To investigate the prevalence, mortalities, and patient characteristics of Acute-on-chronic liver failure (ACLF according to the AARC (Asian Pacific Association for the Study of the Liver ACLF Research Consortium and European Association for the Study of the Liver CLIF-C (Chronic Liver Failure Consortium definitions.We collected retrospective data for 1470 hospitalized patients with chronic liver disease (CLD and acute deterioration between January 2013 and December 2013 from 21 university hospitals in Korea.Of the patients assessed, the prevalence of ACLF based on the AARC and CLIF-C definitions was 9.5% and 18.6%, respectively. The 28-day and 90-day mortality rates were higher in patients with ACLF than in those without ACLF. Patients who only met the CLIF-C definition had significantly lower 28-day and 90-day survival rates than those who only met the AARC definition (68.0% vs. 93.9%, P<0.001; 55.1% vs. 92.4%, P<0.001. Among the patients who had non-cirrhotic CLD, the 90-day mortality of the patients with ACLF was higher than of those without ACLF, although not significant (33.3% vs. 6.0%, P = 0.192. Patients with previous acute decompensation (AD within 1- year had a lower 90-day survival rate than those with AD more than 1 year prior or without previous AD (81.0% vs. 91.9% or 89.4%, respectively, all P<0.001. Patients who had extra-hepatic organ failure without liver failure had a similar 90-day survival rate to those who had liver failure as a prerequisite (57.0% vs. 60.6%, P = 0.391.The two ACLF definitions result in differences in mortality and patient characteristics among ACLF patients. We suggest that non-cirrhotic CLD, previous AD within 1 year, and extra-hepatic organ failure should be included in the ACLF diagnostic criteria. In addition, further studies are necessary to develop a universal definition of ACLF.

    Objective To assessment short-term prognosis in patients with acute on chronic liver failure , several scoring systems were compared. Methods Two hundred and sixteen patients with acute on chronic liver failure were divided into survival group and death group according to the results of 90 days after admission.CTP , MELD,APACHEⅡ, SOFA and SMSVH score were calculated.After ROC curves were performed ,the areas under the curves of these scoring systems were compared. Results The areas under the ROC curves of MELD, APACHEⅡ, SOFA, CTP and SMSVH were 0.88, 0.76, 0.89,0.79and 0.69,respectively. The areas under the curves of SOFA and MELD were larger than the APACHEⅡ, CTP and SMSVH (P0.05). The area under the curve of CTP was larger than the APACHEⅡ, but there was no statistically significant difference (P > 0.05). The area under the curve of SMSVH were less than 0.7. Conclusions The SOFA, MELD,CTP and APACHEⅡcan predict the short-term prognosis of acute on chronic liver failure. The SOFA and MELD are the best scoring systems.CTP,APACHEⅡ are better than SMSVH. SMSVH fail to predict the prognosis of acute on chronic liver failure.%目的:通过对几种不同评分系统比较,找出更适合乙肝相关慢加急性肝衰竭患者短期预后评估的方法。方法:将142例乙肝相关慢加急性肝衰竭患者根据其3个月后的存活及死亡情况,分为存活组(n=72)及病死组(n=70),分别计算 CTP、MELD、ANN、SOFA 、SMSVH 、LRM 等评分,行 ROC 曲线分析,计算曲线下面积,并进行比较。结果:ROC曲线下面积从大到小分别为ANN、SOFA 、LRM、MELD、CTP、SMSVH ,相应数值分别为0.92、0.89、0.89、0.87、0.78和0.69。ANN、SOFA 、LRM、MELD的AUC之间比较差异无统计学意义(P >0.05),ANN、SOFA 、LRM、MELD 的 AUC 值> CTP、SMSVH,差异有统计学意义(P 均<0.05), CTP 的 AUC 值>SMSVH,差异有统计学意义(P<0.05

  3. Peritoneal dialysis in acute renal failure in canines: A review

    Directory of Open Access Journals (Sweden)

    R. H. Bhatt

    Full Text Available Peritoneal dialysis is a technique whereby infusion of dialysis solution into the peritoneal cavity is followed by a variable dwell time and subsequent drainage. During peritoneal dialysis, solutes and fluids are exchanged between the capillary blood and the intraperitoneal fluid through a biologic membrane, the peritoneum. Inadequate renal function leads to disturbance in the removal of the extra fluid and waste products. It removes the waste product and extra fluid from the body in renal failure in small animal practice. Peritoneal dialysis is more accessible, more affordable and easier to administer to the small animal patient. The most common indication for peritoneal dialysis in dogs is acute renal failure (ARF. Peritoneal dialysis is an important therapeutic tool for mitigating clinical signs of uremia and giving the kidneys time to recover in cats with acute kidney injury when conventional therapy is no longer effective.

  4. Low levels of blood lipids are associated with etiology and lethal outcome in acute liver failure.

    Directory of Open Access Journals (Sweden)

    Paul Manka

    Full Text Available Emerging data links different aspects of lipid metabolism to liver regeneration. In patients with acute liver failure (ALF, low levels of lipids may correlate with disease severity. Thus, we determined whether there is an etiology-specific link between lipid levels in patients suffering from ALF and aimed to investigate an effect of lipid levels on the prognosis of ALF.In this retrospective single center study, we reviewed 89 consecutive ALF patients, who met the criteria of the "Acute Liver Failure Study Group". Patient characteristics, clinical data and laboratory parameters were individually analyzed at admission and correlated with the patients' outcome after a four week follow up. Possible endpoints were either discharge, or death or liver transplantation.High-density lipoprotein (HDL, cholesterol and triglyceride levels were significantly lower in patients who died or required a liver transplant. HDL levels were significantly higher in patients with ALF caused by acetaminophen intoxication, compared to fulminant HBV infection or drug induced liver injury. HDL levels correlated with hepatic injury by ALT levels, and Albumin, and inversely correlated with the MELD score, INR, and bilirubin.In our cohort of patients with ALF, we could show that HDL and cholesterol are suppressed. In addition novel etiology specific patterns between acteminophen and non-acteminophen induced liver failure were detected for serum lipid components. Further studies are needed to address the role of cholesterol and lipid metabolism and the according pathways in different etiologies of ALF.

    Hemophagocytic lymphohistiocytosis (HLH) is a syndrome of excessive immune activation that mimics and occurs with other systemic diseases. A 35-year-old female presented with signs of viral illness at 13 weeks of pregnancy and progressed to acute liver failure (ALF). We discuss the diagnosis of HLH and Kikuchi-Fujimoto (KF) lymphadenitis in the context of pregnancy and ALF. HLH may respond to comorbid disease-specific therapy, and more toxic treatment can be avoided.

    Full Text Available Immune response plays an important role in the development of hepatic fibrosis. In the present study, we investigated the effects of quercetin on hepatitis and hepatic fibrosis induced by immunological mechanism. In the acute hepatitis model, quercetin (2.5 mg/kg was injected iv into mice 30 min after concanavalin A (Con A challenge. Mice were sacrificed 4 or 24 h after Con A injection, and aminotransferase tests and histopathological sections were performed. Treatment with quercetin significantly decreased the levels of alanine aminotransferase (ALT and aspartate aminotransferase (AST. Consistent with this observation, treatment with quercetin markedly attenuated the pathologic changes in the liver. A hepatic fibrosis model was also generated in mice by Con A challenge once a week for 6 consecutive weeks. Mice in the experimental group were treated with daily iv injections of quercetin (0.5 mg/kg. Histopathological analyses revealed that treatment with quercetin markedly decreased collagen deposition, pseudolobuli development, and hepatic stellate cells activation. We also examined the effects of quercetin on the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB and transforming growth factor beta (TGF-β pathways by immunohistochemistry and real-time reverse transcriptase-polymerase chain reaction (RT-PCR. NF-κB and TGF-β production was decreased after treatment with quercetin, indicating that the antifibrotic effect of quercetin is associated with its ability to modulate NF-κB and TGF-β production. These results suggest that quercetin may be an effective therapeutic strategy in the treatment of patients with liver damage and fibrosis.

  9. Perirenal effusion in dogs and cats with acute renal failure.

    2007-01-01

    Perirenal fluid accumulation has been described as an ultrasonographic feature of urine leakage, hemorrhage, abscessation, or neoplasia. The purpose of this retrospective study was to report perirenal effusion as an additional ultrasonographic finding in canine and feline patients with acute renal failure. The causes of acute renal failure in 18 patients included nephrotoxicity (4), leptospirosis (3), ureteral obstruction (2), renal lymphoma (2), ureteronephrolithiasis (2), prostatic urethral obstruction (1) and interstitial nephritis and ureteritis (1). An underlying cause was not identified in three patients. The sonographic finding of perirenal fluid was bilateral in 15 patients. Unilateral perirenal fluid was identified ipsilateral to the site of ureteric obstruction in two patients. Large effusions extended into the caudal retroperitoneal space. Additional sonographic findings suggestive of renal parenchymal disease included mild (5), moderate (5) or severe (2) pyelectasia, increased renal echogenicity (11), increased (9) or decreased renal size (2) and ureteral and/or renal calculi (3). There did not appear to be an association between the volume of perirenal fluid and the severity of renal dysfunction. All patients with large effusions underwent euthanasia. Perirenal fluid developing in acute renal failure is thought to be an ultrafiltrate associated with tubular back-leak into the renal interstitium that overwhelms lymphatic drainage within the perirenal and retroperitoneal connective tissues although obstruction to urine flow may also play a role. Localized perirenal retroperitoneal free fluid may be a useful ultrasonographic feature to assist with the characterization of, and determination of prognosis in, patients with suspected renal disease.

    Malcolm Lemyze

    Full Text Available PURPOSE: Acute respiratory failure (ARF is a common life-threatening complication in morbidly obese patients with obesity hypoventilation syndrome (OHS. We aimed to identify the determinants of noninvasive ventilation (NIV success or failure for this indication. METHODS: We prospectively included 76 consecutive patients with BMI>40 kg/m2 diagnosed with OHS and treated by NIV for ARF in a 15-bed ICU of a tertiary hospital. RESULTS: NIV failed to reverse ARF in only 13 patients. Factors associated with NIV failure included pneumonia (n = 12/13, 92% vs n = 9/63, 14%; p<0.0001, high SOFA (10 vs 5; p<0.0001 and SAPS2 score (63 vs 39; p<0.0001 at admission. These patients often experienced poor outcome despite early resort to endotracheal intubation (in-hospital mortality, 92.3% vs 17.5%; p<0.001. The only factor significantly associated with successful response to NIV was idiopathic decompensation of OHS (n = 30, 48% vs n = 0, 0%; p = 0.001. In the NIV success group (n = 63, 33 patients (53% experienced a delayed response to NIV (with persistent hypercapnic acidosis during the first 6 hours. CONCLUSIONS: Multiple organ failure and pneumonia were the main factors associated with NIV failure and death in morbidly obese patients in hypoxemic ARF. On the opposite, NIV was constantly successful and could be safely pushed further in case of severe hypercapnic acute respiratory decompensation of OHS.

    2015-11-01

    Full Text Available Chronic hepatitis B virus (HBV infection is a major global health problem with an estimated 400 million HBV carriers worldwide. In the natural history of chronic hepatitis B (CHB, spontaneous acute exacerbation (AE is not uncommon, with a cumulative incidence of 10%–30% every year. While exacerbations can be mild, some patients may develop hepatic decompensation and even die. The underlying pathogenesis is possibly related to the activation of cytotoxic T lymphocyte-mediated immune response against HBV. An upsurge of serum HBV DNA usually precedes the rise of alanine aminotransferase (ALT and bilirubin. Whether antiviral treatment can benefit CHB with severe AE remains controversial, but early nucleos(tide analogues treatment seemed to be associated with an improved outcome. There has been no randomized study that compared the effects of different nucleos(tide analogues (NA in the setting of CHB with severe AE. However, potent NAs with good resistance profiles are recommended. In this review, we summarized current knowledge regarding the natural history, pathogenetic mechanisms, and therapeutic options of CHB with severe AE.

    Liver abnormalities in the course of Adult Onset Still's Disease (AOSD), both in form of hepatomegaly and elevation of hepatic enzymes, have been reported in up to three-quarts of the affected patients. These abnormalities may reflect disease activity or may be induced by drugs. Only in a few of this patients a liver biopsy was performed. However liver histology has shown, generally, non specific abnormalities or even normal pictures. We have recently observed a 47-year-old woman with a febrile illness started five months before, who after pertinent investigation was diagnosed as AOSD (according to criteria of Yamaguchi et al.). Apart from laboratory findings characteristic of an inflammatory disease, in absence of drug therapies the biochemical data showed raised levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and aminoglutamil transferase. Serological tests for either viral hepatitis viruses (HAV, HBV, HCV) or other viruses were negative. Ultrasonographic examination of gallbladder and bile ducts did not find gallstones or other abnormalities. A liver biopsy was performed, which histopathologic examination showed moderate fatty methamorphosis with focal areas of hepatocellular swelling with minimal necrosis, mild Kuppfer cell hyperplasia, portal and sinusoidal infiltrates of mononuclear cells. This picture consisted with the diagnosis of an acute unspecific reactive hepatitis.

    Hepatic artery pseudoaneurysm (HAP) is a very rare disease but in cases of complication,there is a very high mortality.The most common cause of HAP is iatrogenic trauma such as liver biopsy,transhepatic biliary drainage,cholecystectomy and hepatectomy.HAP may also occur with complications such as infections or inflammation associated with septic emboli.HAP has been reported rarely in patients with acute pancreatitis.As far as we are aware,there is no report of a case caused by acute idiopathic pancreatitis,particularly.We report a case of HAP caused by acute idiopathic pancreatitis which developed in a 61-year-old woman.The woman initially presented with acute pancreatitis due to unknown cause.After conservative management,her symptoms seemed to have improved.But eight days after admission,abdominal pain abruptly became worse again.Abdominal computed tomography (CT) was rechecked and it detected a new HAP that was not seen in a previous abdominal CT.Endoscopic retrograde cholangiopancreatography (ERCP) was performed because of a suspicion of hemobilia as a cause of aggravated abdominal pain.ERCP confirmed hemobilia by observing fresh blood clots at the opening of the ampulla and several filling defects in the distal common bile duct on cholangiogram.Without any particular treatment such as embolization or surgical ligation,HAP thrombosed spontaneously.Three months after discharge,abdominal CT demonstrated that HAP in the left lateral segment had disappeared.

    A 23-year-old nulliparous woman, a hepatitis B virus (HBV) carrier with stable liver functions, presented with exacerbation of viral replication (HBV DNA level >9.0 log copies/mL) in gestational week 26. During the subsequent follow up without antiviral therapy, she was hospitalized with progression to hepatic failure in gestational week 35. Following initiation of antiviral therapy with lamivudine, emergent cesarean delivery was conducted for fetal safety. Liver atrophy and persistent hepatic encephalopathy (stage 2) necessitated artificial liver support (ALS) involving online hemodiafiltration (HDF) and plasma exchange. She regained full consciousness after the sixth online HDF session. ALS was terminated after the seventh online HDF session. On day 33 of hospitalization, she was discharged home without sequelae. Genetic analysis of the HBV strain isolated from her serum showed that this strain had genotype C. Direct full-length sequencing identified no known mutations associated with fulminant hepatitis B. HBV-related hepatic failure observed in the present case might have been related to perinatal changes in the host immune response.

    The short-term prognosis of patients with severe acute exacerbation of chronic hepatitis B (CHB) leading to acute liver failure is extremely poor. We have reported the efficacy of corticosteroid in combination with nucleoside analogue in the early stages, but virological efficacy has not been documented. Our aim was to elucidate the virological efficacy of this approach. Thirteen patients defined as severe acute exacerbation of CHB by our uniform criteria were prospectively examined for virological responses to treatment. Nucleoside analogue and sufficient dose of corticosteroids were introduced as soon as possible after the diagnosis of severe disease. Of the 13 patients, 7 (54%) survived, 5 (38%) died and 1 (8%) received liver transplantation. The decline of HBV DNA was significant between the first 2 weeks (P = 0.02) and 4 weeks (P analogue has sufficient virological effect against severe acute exacerbation of CHB, and a rapid decline of HBV DNA is conspicuous in survived patients.

    Adult giant cell hepatitis (AGCH) is a rare event and only about 100 cases have been reported within the last 20 years. The AGCH has been observed in association with viral infection, drug reactions or autoimmune disorders but in many cases its etiology remains unclear. AGCH manifests clinically as severe form of hepatitis histologically characterized by diffuse giant cell transformation of hepatocytes. We report the case of a 39-yr-old man with acute community-acquired hepatitis without previous pathology of the liver. Laboratory data revealed slight hypergammaglobulinemia and high titer of anti-smooth-muscle antibody with negative serology of hepatotropic viruses and absence of other known causes of hepatitis. Preliminary diagnosis of autoimmune hepatitis was established, additionally confirmed by excellent clinical and biochemical improvement during corticosteroid treatment. A liver biopsy showed the typical findings of panlobular syncytial giant cell hepatitis and positive HCV-RNA both in serum and liver. The above verified the diagnosis of acute type C hepatitis manifested histologically as adult giant cell hepatitis. After three months of treatment we withdrew corticosteroids as spontaneous clearance of HCV occurred and the lack of autoantibodies in serum as well as significant improvement of liver histology was ascertained. Within 30 months of the follow-up we have not observed biochemical and immunological abnormalities and control liver biopsy has shown no signs of hepatitis.

    Full Text Available Abstract Background Invasive pulmonary aspergillosis (IPA is a rapid, progressive, fatal disease that occurs mostly in immunocompromised patients. Patients with severe liver disease are at a heightened risk for infections. Little is known about the clinical presentation including predisposing factors and treatment of IPA in patients with hepatic failure. Methods Medical records of patients with hepatic failure between November 2005 and February 2007 were reviewed for lung infection. Nine medical records of definitive diagnosis of IPA and three of probable IPA were identified. Results The main predisposing factors were found to be prolonged antibiotic therapy and steroid exposure. Clinical signs and radiological findings were non-specific and atypical. Timely use of caspofungin was found to reduce the mortality due to the disease. Conclusion A high index of suspicion is required for early IPA diagnosis in patients with hepatic failure.

    2014-09-01

    In patients with acute heart failure (AHF) syndromes, little data are so far available on the relation between glucose values and insulin resistance and mortality, both in the short and long term. The present review is aimed at summarizing available evidence on the prognostic role of hyperglycemia in acute heart failure syndromes. Despite the fact that glucose values are widely measured, inexpensive, and easy to interpret, hyperglycemia in AHF patients still appears to be (or at least to have been) a neglected factor. Scarce information is available on incidence of admission hyperglycemia (especially in nondiabetic AHF patients) and data on in-hospital and discharge glucose values are lacking. Overall, the scarcity of data and the unanswered questions conjure up the need for trials investigating the clinical and prognostic role of glucose abnormalities (hyperglycemia and acute insulin resistance) on admission and during hospital stay in AHF patients. Preliminary evidence suggests that hyperglycemia is an important prognostic factor in AHF; however, whether targeting hyperglycemia via an aggressive versus permissive glycemic management strategy influences AHF outcomes remains unknown.

  12. Paroxysmal nocturnal hemoglobinuria: rare cause of acute renal failure

    2012-12-01

    Full Text Available Paroxysmal nocturnal hemoglobinuria is a rare acquired disease, characterized by hemolytic anemia, recurrent infections, cytopenias, and vascular thrombosis. It occurs by non-malignant clonal expansion of one or more hematopoietic stem cells that acquired somatic mutations in PIG-A gene linked to chromosome X. This mutation results in lower erythrocyte expression of CD55 and CD59 surface proteins and consequently increased susceptibility to the complement system. The renal involvement is generally benign, resulting in mild impairment in urinary concentration. Acute renal failure requiring hemodialytic support accompanying PNH is rarely observed. The authors report a case of a 37-year-old male who presented with bicytopenia (hemolytic anemia and thrombocytopenia associated with acute renal failure requiring dialysis. Diagnosis was challenging because of the rarity and unfamiliarity with this entity, but was confirmed by flow cytometry. In the course of the disease, acute pyelonephritis with multiple renal abscesses was diagnosed requiring prolonged antibiotic therapy. Patient outcome was favorable after the control of hemolysis and the infection treatment.

  13. Novel biomarkers in acute heart failure: MR-pro-adrenomedullin.

    Science.gov (United States)

    Peacock, W Frank

    2014-10-01

    First isolated from human pheochromocytoma cells, adrenomedullin (ADM) is a peptide hormone with natriuretic, vasodilatory, and hypotensive effects mediated by cyclic adenosine monophosphate (cAMP), nitric oxide, and renal prostaglandin systems. ADM expression occurs in many tissues and organ systems, including cardiovascular, renal, pulmonary, cerebrovascular, gastrointestinal, and endocrine tissues where it acts as a circulating hormone and a local autocrine and paracrine hormone. ADM plasma concentrations are increased in hypertension, chronic renal disease, and heart failure. As ADM is unstable in vitro, it is necessary to measure its mid-regional pro-hormone fragment, the levels of which correspond to ADM concentration (MR-proADM). The prognostic potential of MR-proADM was recently demonstrated in the Biomarkers in Acute Heart Failure (BACH) trial. In this trial of 568 acute heart failure patients, MR-proADM was superior to both brain natriuretic peptide (BNP) and NT-proBNP in predicting mortality within 14 days. MR-proADM also provided significant additive incremental predictive value for 90-day mortality when added to BNP and NT-proBNP.

    `Hematologic malignancies (leukemia, lymphoma, multiple myeloma, et al.), as well as solid tumours (renal, liver, lung, ovarian, etc.), can lead to acute or chronic renal failure.The most common clinical manifestation is acute renal failure within the tumour lysis syndrome (TLS). It is characterized by specific laboratory and clinical criteria in order to prove that kidney disorders result from cytolysis of tumour cells after chemotherapy regimen given, although on significantly fewer occasions it is likely to occur spontaneously or after radiotherapy. Essentially, failure is the disorder of functionally conserved kidney or of kidney with varying degrees of renal insufficiency, which render the kidney impaired and unable to effectively eliminate the end products of massive cytolysis and to correct the resulting disorders: hyperuricemia, hyperkalemia, hypocalcaemia, hyperphosphatemia, and others. The risk of TLS depends on tumour size, proliferative potential of malignant cells, renal function and the presence of accompanying diseases and disorders. Hydration providing adequate diuresis and administration of urinary suppressants (allopurinol, febuxostat) significantly reduce the risk of developing TLS. If prevention of renal impairment isn't possible, the treatment should be supplemented with hemodynamic monitoring and pharmacological support, with the possible application of recombinant urate-oxidase enzyme (rasburicase). Depending on the severity of azotemia and hydroelectrolytic disorders, application of some of the methods of renal replacement therapy may be considered.

    Renal involvement is a common finding in non-Hodgkin's lymphoma (NHL). Acute renal failure at initial presentation due to lymphomatous infiltration of the kidneys has been described infrequently. We report a 17-year-old male who presented with acute renal failure due to massive lymphomatous infiltration of the kidneys, which necessitated hemodialysis. The diagnosis of B-cell NHL was established by tru-cut biopsy of the kidneys and the patient had an excellent response to high-dose chemotherapy with no major complication. The presence of extrarenal involvement in the testes and the retroperitoneal lymph nodes made the diagnosis of primary renal lymphoma debatable. However, considering the delay in diagnosis and the high proliferative rate of B-cell NHL, we might postulate that the disease had originated primarily in the kidneys. We recommend that in NHL cases with severe renal involvement, full-dose chemotherapy should be instituted with meticulous clinical and laboratory follow-up in order to improve clinical and renal failure status rapidly and to avoid further dissemination of NHL.

    Full Text Available Kikuchi-Fujimoto disease, also known as histiocytic necrotizing lymphadenitis of unknown etiopathogenesis, is a self-limited disease which frequently appears as feverish lymphadenomegaly, thus creating the need for differential diagnosis with lymphoma, systemic lupus erythematosus (SLE, infectious mononucleosis, cat-scratch disease, and toxoplasmosis with lymphonodal impairment. However, there are cases in which it may evolve with complications such as aseptic meningitis, cerebellar ataxia, and aseptic myocarditis. We are presenting a case of a 24-year-old man who had an initial picture of arthralgia, evening fever and adenomegaly. Kikuchi disease was diagnosed through lymph node biopsy with immunohistochemistry and evolves with severe systemic manifestations, such as pericarditis with cardiac tamponade, pneumonitis, hepatitis, and acute kidney failure - the latter has not been reported in literature yet. There was significant improvement of the clinical picture with prednisone

    Patients with hepatic hemangiomas have been known to have high-output heart failure as a result of left-to-right arteriovenous shunting. We report a patient with a hepatic hemangioma that presented with high-output heart failure with hypoxia on exertion. After embolization of the hemangioma, the patient's hypoxia resolved and ejection fraction improved. In the absence of cardiopulmonary pathophysiology, we presume that our patient's hemangioma was causing a right-to-left shunt as opposed to an expected left-to-right shunt.

    Hereditary fructose intolerance is a rare inherited metabolic disorder. Although fructose intolerance usually presents in the paediatric age group, individuals can survive into adulthood by self.manipulation of diet. Hospitalisation can become a high.risk environment for these individuals because of loss of control of their strict dietary constraints and the added danger of administration of medications containing fructose, sucrose and sorbitol. We report a case of hereditary fructose intolerance in an adult presenting with hepatic and renal failure associated with an amiodarone infusion and explore the possibility of polysorbate 80 as a cause of this patient's hepatic and renal failure.

    Full Text Available Venomous snakebite is a common problem in India. The aim of this study is to assess the prevalence, risk factors and prognostic factors in snakebite induced acute renal failure and to determine their outcome from a tertiary care center in India. A total of 1548 cases of snakebite admitted to adult medical wards of Government Rajaji hospital from January 2003 to December 2004, were studied from hospitalization to discharge or death. There were 1180 poisonous and 368 nonpoisonous snakebites. Among the poisonous, there were 1121 viperidae and 59 elapidae bites. A total of 159 (13.5% patients (M = 98, F = 61 developed acute renal failure; of them 72 (45.3% required dialysis and 36 (22.6% expired (of them, 23 required dialysis.

Cellulites (OR 9.20, p = 0.032, regional lymphadenopathy (OR 22.0, p= 0.001, intravascular hemolysis (OR 3.70, p = 0.004 and bite to needle time more than 2 hours (OR 2.10, p = 0.001 were identified as independent risk factors for the development of acute renal failure. Bite to needle time more than 2 hours (OR 2.10, p = 0.01, presence of intravascular hemolysis (OR 13.0, p = 0.004 and hypotension (OR 22.2, p = 0.04 and the presence of bleeding manifestations (OR 7.91, p = 0.032 were identified as independent predictors of poor outcome in snakebite victims. We conclude that our study demonstrates several risk factors and predictors for the development and outcome of ARF in patients with snakebites.

    Acute kidney injury (AKI) is an important clinical issue, especially in the setting of critical care. It has been shown in multiple studies to be a key independent risk factor for mortality, even after adjustment for demographics and severity of illness. There is wide agreement that a generally applicable classification system is required for AKI which helps to standardize estimation of severity of renal disfunction and to predict outcome associated with this condition. That's how RIFLE (Risk-Injury-Failure-Loss-End-stage renal disease), and AKIN (Acute Kidney Injury Network) classifications for AKI were found in 2004 and 2007, respectively. In the clinical setting of heart failure, a positive fluid balance (often expressed in the literature as weight gain) is used by disease management programs as a marker of heart failure decompensation. Oliguria is defined as urine output less than 0,3 ml/kg/h for at least 24 h. Since any delay in treatment can lead to a dangerous progression of the AKI, early recognition of oliguria appears to be crucial. Critically ill patients with oliguric AKI are at increased risk for fluid imbalance due to widespread systemic inflammation, reduced plasma oncotic pressure and increased capillary leak. These patients are particulary at risk of fluid overload and therefore restrictive strategy of fluid administration should be used. Objective, rapid and accurate volume assessment is important in undiagnosed patients presenting with critical illness, as errors may result in interventions with fatal outcomes. The historical tools such as physical exam, and chest radiography suffer from significant limitations. As gold standard, radioisolopic measurement of volume is impractical in the acute care enviroment. Newer technologies offer the promise of both rapid and accurate bedside estimation of volume status with the potential to improve clinical outcomes. Blood assessment with bioimpendance vector analysis, and bedside ultrasound seem to be

    Imaging techniques, especially ultrasonography and Doppler, can give an effective assistance in the differential diagnosis of acute renal failure (ARF). An resistance Index (RI) value >0.75 is reported as optimal in attempting differential diagnosis between acute tubular necrosis (ANT) and prerenal ARF. In hepatorenal syndrome (HRS) RIs is very increased. In some renal vasculitis, as nodose panarteritis (PN), hemolytic-uremic syndrome (HUS), thrombotic thrombocytopenic purpura (TTP), parenchymal perfusion is reduced and RI increased. In lupus nephritis the RI values are correlated with creatinine level and normal RI are considered as a good prognostic tool. In acute primitive or secondary glomerulonephritis (GN), RI value is normal, with diffuse parenchymal hypervascularization. In acute crescentic and proliferative GN and tubulo-interstitial disease, color Doppler (CD) and power Doppler (PD) reveal a decreased renal parenchymal perfusion, which correlates with increased RI values. In acute thrombosis of renal artery, US color Doppler (DUS) reveals either an absence of Doppler signal or a tardus-parvus pulse distal to the vascular obstruction. In this situation it is possible to visualize hyperthropic perforating vessels that redirect their flow from the capsular plexus to the renal parenchyma. In acute thrombosis of the renal vein Doppler analysis of parenchymal vessels reveals remarkable RI values, sometimes with reversed diastolic flow. In postrenal ARF an adjunct to the differentiation between obstruction and non obstructive dilatation can be found through RIs. Diagnostic criteria of obstruction as reported by literature are: RI>0.70 in the obstructed kidney and, mostly, a difference in RI between the 2 kidneys >0.06-0.1.

    Full Text Available Acute renal failure (ARF in patients with malignancy occurs due to causes such as prerenal, renal and post renal as in normal population. Tumor infiltration of kidneys is usually uncommon. However, renal function may be impaired in fast-growing hematological malignancies such as acute leukemia or lymphoma, depending on tumor involvement. Herein, we presented a case of ARF and later diagnosed as B-cell Non-Hodgkin's lymphoma. 54-year-old male patient was admitted due to ARF. Although development of ARF due to tumor infiltration is rare, in cases who did not have risk factors for development of ARF, leukemic or lymphomatous infiltration should be considered.

    Full Text Available Acute renal failure (ARF is a common complication of sepsis and carries a high mortality. Renal replacement therapy (RRT during the acute stage is the mainstay of therapy. Va-rious modalities of RRT are available. Continuous RRT using convective methods are preferred in sepsis-induced ARF, especially in hemodynamically unstable patients, although clear evidence of benefit over intermittent hemodialysis is still not available. Peritoneal dialysis is clearly inferior, and is not recommended. Early initiation of RRT is probably advantageous, although the optimal timing of dialysis is yet unknown. Higher doses of RRT are more likely to be beneficial. Use of bio-compatible membranes and bicarbonate buffer in the dialysate are preferred. Anticoagulation during dialysis must be carefully adjusted and monitored.

    2013-08-20

    Interstitial pneumonitis as an adverse effect of mesalamine therapy is a rare but potentially serious complication. Patients typically have a mild disease course with no documented cases of respiratory failure in published literature. Given its variable latent period and non-specific signs and symptoms, it may be difficult to diagnose. We present the case of a 65-year-old man who presented with symptoms of fever, shortness of breath and a non-productive cough, 2 weeks after initiation of therapy with mesalamine. His hospital course was complicated by acute respiratory failure requiring intubation and mechanical ventilation. Radiographic studies revealed bilateral lower lobe infiltrates and bronchosopy with bronchoalveolar lavage and transbronchial biopsy were consistent with a diagnosis of drug-induced interstitial pneumonitis. The aim of this paper is to highlight the importance of considering a diagnosis of mesalamine-induced lung injury in patients presenting with respiratory symptoms while on mesalamine therapy and to review relevant literature.

    Full Text Available Objective. To present a case of a healthy 41-year-old female who developed fulminant hepatic failure leading to death. The cause of hepatic failure identified on postmortem exam was herpes simplex virus hepatitis. Design. Observation of a single patient. Setting. Intensive care unit of a tertiary care university teaching hospital in Canada. Patient. 41-year-old previously healthy female presenting with a nonspecific viral illness and systemic inflammatory response syndrome. Intervention. The patient was treated with intravenous fluids and broad-spectrum antibiotics. On the second day of admission, she was found to have elevated transaminases, and, over 48 hours, she progressed to fulminant liver failure with disseminated intravascular coagulopathy, refractory lactic acidosis, and shock. She progressed to respiratory failure requiring intubation and mechanical ventilation. She was started on N-acetylcysteine, a bicarbonate infusion, hemodialysis, and multiple vasopressors and inotropes. Measurements and Main Results. Despite treatment, the patient died roughly 70 hours after her initial presentation to hospital. Her postmortem liver biopsy revealed herpes simplex virus hepatitis as her cause of death. Conclusions. Herpes simplex virus must be considered in all patients presenting with liver failure of unknown cause. If suspected, prompt treatment with acyclovir should be initiated.

    Alagille syndrome (AS) is an autosomal-dominant, multisystem disorder affecting the liver, heart, eyes, skeleton, and face. The manifestations are predominantly pediatric. Diagnosis is based on findings of a paucity of bile ducts on liver biopsy combined with ≥3 of 5 major clinical criteria. Orthotopic liver transplantation (OLT) is the only option for treating patients who developed liver failure, portal hypertension, severe itching, and xanthomatosis. It is difficult to establish clear criteria for OLT; indications are controversial because of the wide variety of clinical symptoms and the multisystem involvement. Generally, AS-associated liver disease is never an acute illness. We report the case of a 28-year-old woman with AS who underwent urgent OLT for acute liver failure. At 24 months posttransplant, the patient is in good clinical condition and with normal hepatic and renal function.

Hypoxemic ARF related to ALI/ARDS and pneumonia show worst outcome: it is not advisable to manage these conditions with NIV outside the ICU. NIV for ARF due to COPD and ACPE is feasible, safe and effective in a general medical ward if selection of Pts, staff’s training and monitoring are appropriate. This should encourage the diffusion of NIV in this specific setting. According to strong evidences in literature, NIV should be considered a first line and standard treatment in these clinical conditions irrespective of the setting.

    Hepatitis E is considered to be a worldwide public health problem. Although the prevalence of hepatitis E virus (HEV) antibodies in healthy individuals is noted to be 11%, no patients with acute hepatitis E have previously been identified in Mongolia. Three hundred two consecutive patients (183 males and 119 females; median age of 22.0 [Interquartile range: 18.3-25.0] years) who were clinically diagnosed with sporadic acute hepatitis during 2012-2013 in Ulaanbaatar, Mongolia, were studied. By serological and/or molecular approaches, 77 (25.5%), 93 (30.8%), 19 (6.3%), 48 (15.9%), and 12 (4.0%) of the patients were diagnosed with acute hepatitis of types A, B, C, D (superinfection of hepatitis delta virus on a background of chronic hepatitis B virus infection) and E, respectively, while the cause of hepatitis was unknown in the remaining 53 patients (17.5%). The 12 hepatitis E patients had no history of travel abroad in the 3 months before the onset of disease, and lived separately in fixed or movable houses with water supplied via pipe, tank or well, denying transmission from a common water supply. The 12 HEV isolates obtained from the patients showed high nucleotide identities of 99.7-100%, and a representative HEV isolate, MNE13-227, was closest to the Chinese isolates of genotype 4, with the highest identity of 97.3% in the 304-nt ORF2 sequence and 92.1% over the entire genome. The present study revealed the occurrence of autochthonous acute hepatitis E in Mongolia, caused by a monophyletic genotype 4 HEV strain.

    AIM: Elevation of alanine aminotransferase (ALT) level iscommonly seen among patients suffering from severe acute respiratory syndrome (SARS). We report the progression and clinical significance of liver derangement in a large cohort of SARS patient.METHODS: Serial assay of serum ALT was followed in patients who fulfilled the WHO criteria of SARS. Those with elevated ALT were compared with those with normal liver functions for clinical outcome. Serology for hepatitis B virus (HBV) infection was checked. Adverse outcomes were defined as oxygen desaturation, need of intensive care unit (ICU) and mechanical ventilation and death.RESULTS: Two hundred and ninety-four patients wereincluded in this study. Seventy (24%) patients had elevatedserum ALT on admission and 204 (69%) patients hadelevated ALT during the subsequent course of illness. Using peek ALT >5xULN as a cut-off and after adjusting for potential confounding factors, the odds ratio of peek ALT >5x ULN for oxygen desaturation was 3.24 (95%CI 1.23-8.59, P = 0.018), ICU care was 3.70 (95%CT 1.38-9.89, P = 0.009), mechanical ventilation was 6.64 (95%CI 2.22-19.81, P = 0.001) and death was 7.34 (95%CI 2.28-24.89, P = 0.001). Ninety-three percent of the survived patients had ALT levels normalized or were on the improving trend during follow-up. Chronic hepatitis B was not associated with worse clinical outcomes. CONCLUSION: Reactive hepatitis is a common complication of SARS-coronavirus infection. Those patients with severehepatitis had worse clinical outcome.

    Liver transplantation is increasingly accepted as a choice of treatment for fulminant hepatic failure (FHF) since it has been proved to significantly improve the survival rate in these patients compared with other therapeutic modalities. We have successfully performed a total of 76 living related liver transplantations (LRLT) three of which were for FHF. The first case was an 11-year-old boy with FHF due to an unidentified cause. He had required plasmapheresis a total of 24 times and haemofiltration to save his life before LRLT. He was transplanted with a left lobe (420 g) graft, calculated as 1.05% of his weight (40 kg). He recovered hepatic function uneventfully and was discharged from hospital after 7 weeks. The second case was a 13-year-old girl who developed FHF with grade III encephalopathy due to acute Wilson's disease, and was referred to us. She underwent LRLT with a left lobe graft (440 g), estimated as 0.95% of her weight (47 kg), which functioned well after surgery. The third case was a 13-year-old girl with grade II encephalopathy due to acute Wilson's disease. She was 27% obese with a body weight of 58 kg. She underwent LRLT with ABO blood group incompatibility with a left lobe (352 g), estimated as 0.80% of her weight (modified 44 kg). She was discharged with sensorimotor neuropathy due to vitamin B deficiency. The present results suggest that LRLT is feasible for FHF both clinically and ethically, and that a partial liver graft weighing around 1% of the recipient's weight can maintain the recipient's life. We limit the diagnostic indication for LRLT to chronic liver disease, since an urgent situation may affect a voluntary decision for the patient's parents to donate the partial liver. However, LRLT is thought to be an acceptable choice of treatment provided it is requested by the patient and family. Furthermore, it is a potential option for resolving the graft shortage in paediatric liver transplantation, being independent of cadaver donor

    Full Text Available INTRODUCTION: Acute-on-chronic liver failure is characterized by acute deterioration of liver function in patients with compensated or decompensated, but stable, cirrhosis. However, there is no accurate definition of acute-on-chronic liver failure and physicians often use this term to describe different clinical entities. Metabolomics investigates metabolic changes in biological systems and identifies the biomarkers or metabolic profiles. Our study assessed the metabolomic profile of serum using proton nuclear magnetic resonance ((1H-NMR spectroscopy to identify metabolic changes related to acute-on-chronic liver failure. PATIENTS: Ninety-three patients with compensated or decompensated cirrhosis (CLF group but stable liver function and 30 patients with cirrhosis and hospitalized for the management of an acute event who may be responsible of acute-on-chronic liver failure (ACLF group, were fully analyzed. Blood samples were drawn at admission, and sera were separated and stored at -80°C until (1H-NMR spectral analysis. Using orthogonal projection to latent-structure discriminant analyses, various metabolites contribute to the complete separation between these both groups. RESULTS: The predictability of the model was 0.73 (Q(2 Y and the explained variance was 0.63 (R(2 Y. The main metabolites that had increased signals related to acute-on-chronic liver failure were lactate, pyruvate, ketone bodies, glutamine, phenylalanine, tyrosine, and creatinine. High-density lipids were lower in the ALCF group than in CLF group. CONCLUSION: A serum metabolite fingerprint for acute-on-chronic liver failure, obtained with (1H-NMR, was identified. Metabolomic profiling may aid clinical evaluation of patients with cirrhosis admitted into intensive care units with acute-on-chronic liver failure, and provide new insights into the metabolic processes involved in acute impairment of hepatic function.

    Objective To study the clinical characteristics of obstructive sleep apnea syndrome (OSAS) induced acute respiratory failure. Methods The clinical and laboratory characteristics of 9 patients were reviewed. Results 9 patients (8 females, 1 male) presented with obesity and mental disturbance, with a BMI being 44.97 kg /m2, (45.25 kg/m2 in the fe male). The mean age of the group was 67.89 years (61~74 years). All had respiratory acidosis (mean pH 7.17), hypercapni a (mean PaCO2 94.10mmHg) (63.97~143.18mmHg), and hypoxemia (mean PaO2 39mmHg) (29.03~44.03mmHg). During periods of clinical stability all but 2 had awaken hypercapnia (mean PaCO2 46.73mmHg) (38.25~54.68mmHg). Four of the 9 patients had pulmonary function test showing FEV1>70%. Conclusion OSAS induced acute respiratory fail ure has a sudden onset and various presentations and can be reversed with early and proper treatment. The severity of abnormal pulmonary function was less than what would be expected to cause respiratory failure.

    Liver transplantation and blood purification therapy, including plasmapheresis, hemodiafiltration, and bioartificial liver support, are the available treatments for patients with severe hepatic failure. Bioartificial liver support, in which living liver tissue is used to support hepatic function, has been anticipated as an effective treatment for hepatic failure. The two mainstream systems developed for bioartificial liver support are extracorporeal whole liver perfusion (ECLP) and bioreactor systems. Comparing various types of bioartificial liver in view of function, safety, and operability, we concluded that the best efficacy can be provided by the ECLP system. Moreover, in our subsequent experiments comparing ECLP and apheresis therapy, ECLP offers more ammonia metabolism than HD and HF. In addition, ECLP can compensate amino acid imbalance and can secret bile. A controversial point with ECLP is the procedure is labor intensive, resulting in high costs. However, ECLP has the potential to reduce elevated serum ammonia levels of hepatic coma patients in a short duration. When these problems are solved, bioartificial liver support, especially ECLP, can be adopted as an option in ordinary clinical therapy to treat patients with hepatic failure.

    We report the clinical course, imaging findings, and management of a rare case of rapidly involuting congenital hemangioma of the liver in a newborn girl. The baby presented with severe progressive hepatic dysfunction and cardiomegaly. Multimodality imaging demonstrated a large hypervascular solitary hepatic mass with marked transhepatic shunting, consistent with rapidly involuting congenital hemangioma. Because medical therapy failed, transarterial and transvenous embolization was performed with the main intention to improve the hepatic perfusion and function. Unfortunately, despite improvement in the cardiac overload, liver function continued to deteriorate. The baby eventually underwent successful liver transplantation. (orig.)

    Full Text Available Background and Aims: Infection with hepatitis A virus is still one of the most common causes of hepatitis worldwide. The clinical manifestation of acute hepatitis A (AHA in adults can vary greatly, ranging from asymptomatic infection to severe and fulminant hepatitis. The aim of this study was to describe the demographic, clinical characteristics, laboratory features and hospital outcome of adult patients with AHA over a consecutive period of 4 years within an area from Eastern European country. Methods: Two hundred and two adult patients diagnosed with AHA were retrospective, observational and analytic analized over a period of 4 years. Based on prothrombin time less than 50, the study group was stratified in medium (79.2% and severe forms (20.8%. We investigated the clinical, laboratory and epidemiological features. Statistical analysis were applied to compare the medium and severe forms of AHA. Results: Most patients (72.7% were younger than 40 years. The main symptoms included: dyspepsia (72.07%, jaundice (86.63%, asteno-adynamia (86.72%, and flu-like symptoms (53.46%. The hemorrhagic cutaneous-mucous manifestations (6.93% associated with the severe forms of AHA (OR =12.19, 95%CI -3.59 - 41.3, p =0.001.

    Full Text Available We report a case of nephrotic syndrome and acute renal failure apparently induced by sunitinib. A 67-year-old man with a history of metastatic renal cell carcinoma presented with progressive kidney dysfunction with proteinuria, general edema, and body weight gain of 21 kg after undergoing 3 weeks of sunitinib therapy. The patient had taken no other over-the-counter medications, and all other possible causes of nephrotic syndrome were excluded. The Naranjo Adverse Drug Reaction Probability Scale score for this event was 6, indicating a high probability that the observed presentations were associated with use of the drug. However, despite the discontinuation of sunitinib, his condition deteriorated, and hemodialysis was initiated for respiratory distress. A renal biopsy was performed, which revealed ischemic acute tubular necrosis with minimal change nephropathy. In conclusion, nephrologists and oncologists should be aware that nephrotic syndrome with ischemic acute tubular necrosis is a possible adverse effect of sunitinib. For early diagnosis of this condition and to avoid renal damage, we recommend differential diagnosis of serum creatinine and proteinuria in patients undergoing sunitinib therapy.

    Background Heart failure (HF) is a highly prevalent syndrome. Although the long-term prognostic factors have been identified in chronic HF, this information is scarcer with respect to patients with acute HF. despite available data in the literature on long-term prognostic factors in chronic HF, data on acute HF patients are more scarce. Objectives To develop a predictor of unfavorable prognostic events in patients hospitalized for acute HF syndromes, and to characterize a group at higher risk regarding their clinical characteristics, treatment and outcomes. Methods cohort study of 600 patients admitted for acute HF, defined according to the European Society of Cardiology criteria. Primary endpoint for score derivation was defined as all-cause mortality and / or rehospitalization for HF at 12 months. For score validation, the following endpoints were used: all-cause mortality and / or readmission for HF at 6, 12 and 24 months. The exclusion criteria were: high output HF; patients with acute myocardial infraction, acute myocarditis, infectious endocarditis, pulmonary infection, pulmonary artery hypertension and severe mitral stenosis. Results 505 patients were included, and prognostic predicting factors at 12 months were identified. One or two points were assigned according to the odds ratio (OR) obtained (p < 0.05). After the total score value was determined, a 4-point cut-off was determined for each ROC curve at 12 months. Two groups were formed according to the number of points, group A < 4 points, and group B = 4 points. Group B was composed of older patients, with higher number of comorbidities and predictors of the combined endpoint at 6, 12 and 24 months, as linearly represented in the survival curves (Log rank). Conclusions This risk score enabled the identification of a group with worse prognosis at 12 months.

    The aim of this retrospective study was to determine the possible causes of failure of antibiotic therapy in children with acute otitis media (AOM). Thirty-nine samples of middle-ear fluid were obtained by myringotomy from 31 children suffering from AOM, unrelieved by antibiotic therapy administered for over 48 hours. The samples were analysed by the usual microbiological techniques, including cultures, tests for beta-lactamase producing strains and the determination of the minimal inhibitory concentration of penicillin for Streptococcus pneumoniae. In 14 samples, no bacterial strains were detected in the cultures of middle-ear fluid; and in two samples the cultures revealed two strains of bacteria. The bacteria most frequently identified were Haemophilus influenzae, found in 11 samples, and Streptococcus pneumoniae, found in seven samples, of which four produced strains with reduced susceptibility to penicillin. The failure of antibiotic therapy in AOM appears to be related to the increased resistance of Haemophilus influenzae and to the reduced susceptibility of Streptococcus pneumoniae to penicillin. Other factors contributing to the failure of antibiotic therapy in AOM may be the viruses or the bacteria that produce multiple pathogens in the middle ear.

    We present the case of a 63-year-old woman who had undergone 7 months of treatment with Nimesulide (100 mg/b.i.d.) for symptomatic osteoarthritis. The patient was admitted to our unit with a clinical picture of progressive jaundice over 3 weeks. Clinical and analytical studies revealed acute liver failure, this being confirmed by liver biopsy, which showed submassive necrosis. Serological tests for different viral agents causing hepatitis were all negative. In addition, she presented a picture of severe haemolytic anaemia resistant to several treatments and needed multiple transfusions. Twenty-three days after admission, the patient presented hepatic encephalopathy and received an orthotopic liver transplant on day 25. The evolution after transplantation was good and the patient continues in good health with no evidence of haemolysis almost 2 years later. Liver toxicity due to Nimesulide is well known, but to our knowledge the occurrence of haemolytic anaemia has not been related to this drug previously. For these reasons, Nimesulide has been restricted or removed from the market in several countries in recent months.

    Acute liver failure (ALF) is a reversible disorder that is associated with an abrupt loss of hepatic mass, rapidly progressive encephalopathy and devastating complications. Despite its high mortality, an emergency liver transplantation nowadays forms an integral part in ALF management and has substantially improved the outcomes of ALF. Here, we report the case of a 32-year-old female patient who was admitted with grade IV hepatic encephalopathy (coma) following drug-induced ALF. We performed an emergency auxiliary partial orthotopic liver transplantation with a "high risk" graft (liver macrovesicular steatosis approximately 40%) from a living donor. The patient was discharged on postoperative day 57 with normal liver function. Weaning from immunosuppression was achieved 9 mo after transplantation. A follow-up using CT scan showed a remarkable increase in native liver volume and gradual loss of the graft. More than 6 years after the transplantation, the female now has a 4-year-old child and has returned to work full-time without any neurological sequelae.

    Two case-control studies were conducted between January 1994 and August 1995 to determine the relative importance of injections and other exposures as a source of acute hepatitis B in Moldova among adults (aged 15 years) and children (aged 2-15 years). Results showed that injections in various health care settings were associated with acute hepatitis B and showed a higher proportion among adults compared with children. Contact with an HBsAg-positive person was also associated with illnesses; however, there was no statistically significant association between acute hepatitis B and other exposures. The risk of HBV transmission following percutaneous exposure is high (at least 30%). Calculation of the population attributable to risk suggests that injections associated with acute hepatitis B cases occurred in adults (52%) and children (21%). Adverse effects of injections may not be apparent in causing chronic infections. Transmission of blood-borne pathogens through unsafe injection practices is a problem increasingly identified worldwide.

Blood examination revealed elevated transaminase levels and positivity for the IgM anti-HAV antibody; therefore, he was diagnosed with acute hepatitis A. HAV-RNA was detected in his serum and phylogenetically classified as subgenotype IA. The partial genome in the VP1/P2A region was consistent with the strain recently isolated from Surabaya, which indicated that he had been infected during his stay in Indonesia. Thus, HAV vaccination is recommended before visiting HAV-endemic countries for a long period of time.

    In acute alcoholic hepatitis (AAH),a "pseudotumoral" appearance of the liver parenchyma on computed tomography (CT) scan has been reported.The main findings are hypervascularized areas closely similar to those observed in large hepatocellular carcinomas.We report a case of a patient affected by AAH with an unusual appearance of these "pseudotumoral" areas on CT scan,close resembling a metastatic cancer rather than a primary hepatocellular carcinoma.In fact,in contrast with previous reports,the picture was characterized by the presence of many inhomogeneous,hypoattenuated areas highlighted during both pre-and post-contrast phases.Moreover,we report the first description of "pseudotumoral" lesions on ultrasound scan.This patient was successfully treated with corticosteroids,even if many controversies still exist regarding their efficacy in this setting.

    Full Text Available Several studies show the ability of macrophages to remove particles injected into the bloodstream. This function seems to be increased in the presence of acute renal failure. The objective of the present study was to assess the phagocytic function of the main organs (spleen, liver and lung of the mononuclear phagocytic system in renal and postrenal failures. Fifteen rats (250-350 g were divided into three groups (N = 5: group I - control; group II - ligature of both ureters, and group III - bilateral nephrectomy. On the third postoperative day, all animals received an iv injection of 1 ml/kg 99mTc sulfur colloid. Blood samples were collected for the assessment of plasma urea, creatinine, sodium, and potassium concentrations and arterial gasometry. Samples of liver, spleen, lung and blood clots were obtained and radioactivity was measured. Samples of liver, spleen, lung and kidney were prepared for routine histopathological analysis. Plasma urea, creatinine and potassium concentrations in groups II and III were higher than in group I (P<0.05. Plasma sodium concentrations in groups II and III were lower than in group I (P<0.05. Compensated metabolic acidosis was observed in the presence of postrenal failure. Group II animals showed a lower level of radioactivity in the spleen (0.98 and lung (2.63, and a higher level in the liver (105.51 than control. Group III animals showed a lower level of radioactivity in the spleen (11.94 and a higher level in the liver (61.80, lung (11.30 and blood clot (5.13 than control. In groups II and III liver steatosis and bronchopneumonia were observed. Renal and postrenal failures seem to interfere with blood clearance by the mononuclear phagocytic system.

    Chronic hepatitis C is a major cause of chronic liver disease, including liver cirrhosis and hepatocellular carcinoma. The development of direct-acting antivirals (DAAs) revolutionized hepatitis C virus (HCV) treatment by offering genuine prospects for the first comprehensive cure of a chronic viral infection in humans. While antiviral resistance is a significant limitation for interferon-based therapies, resistance and treatment failure still appear to be present in a small fraction of patients even in state-of-the-art DAA combination therapies. Therefore, treatment failure and resistance still remain a clinical challenge for the management of patients not responding to DAAs. In this special issue of Viruses on HCV drug resistance, mechanisms of antiviral resistance for different classes of antiviral drugs are described. Furthermore, the detection and monitoring of resistance in clinical practice, the clinical impact of resistance in different patient groups and strategies to prevent and address resistance and treatment failure using complementary antiviral strategies are reviewed.

    Full Text Available Euphorbia paralias is known in traditional medicine as an anti-inflammatory agent, a purgative and for its local anesthetic property. To the best our knowledge, renal toxicity of this substance has not been previously reported. In this paper, we report the case of a 29-year-old male who developed renal damage following ingestion of Euphorbia paralias. He had been on follow-up for nephrotic syndrome since 1986, although irregularly, with several relapses but each responding well to steroid therapy. A kidney biopsy had not been performed earlier due to refusal by the patient. He was off steroids since April 2008 because the patient developed osteoporosis. He was admitted with general malaise and oliguria to our department in May 2009, following repeated vomiting and watery diarrhea for three days. On examination, he was edematous but had normal vital signs except for a pulse rate of 120/min. Hemoglobin was only 5.5 g/dL but with normal white cell and platelet counts. Blood biochemistry showed evidence of advanced renal failure with a serum creatinine level of 1835 μmol/L and urea at 44.6 mmol/L, sodium of 132 μmol/L and potassium at 4.3 mmol/L. He had features of nephrotic syndrome with severe hypoproteinamia and 24-h urinary protein of 10.45 g. Ultrasonography revealed enlarged kidneys with a reduced echogenecity of the medulla and the papillae. Subsequently, after hemodialysis with blood transfusion, a kidney biopsy was performed that showed focal segmental glomerulosclerosis associated with an acute tubular injury. On intensive interrogation, the patient gave a history of ingesting boiled Euphorbia paralias as a native treatment for edema, ten days prior to the onset of the current illness. A diagnosis of acute renal failure (ARF resulting from the possible nephrotoxic effect of Euphorbia paralias poisoning was made. He was treated with intermittent hemodialysis and corticosteroids.

    Full Text Available Hepatic fibrosis progresses with right heart failure, and becomes cardiac cirrhosis in a severe case. Although its causal factor still remains unclear. Here we evaluated the progression of hepatic fibrosis using a pulmonary artery banding (PAB-induced right heart failure model and investigated whether cardiac output (CO is responsible for the progression of hepatic fibrosis.Five-week-old Sprague-Dawley rats divided into the PAB and sham-operated control groups. After 4 weeks from operation, we measured CO by echocardiography, and hepatic fibrosis ratio by pathological examination using a color analyzer. In the PAB group, CO was significantly lower by 48% than that in the control group (78.2±27.6 and 150.1±31.2 ml/min, P<0.01. Hepatic fibrosis ratio and serum hyaluronic acid, an index of hepatic fibrosis, were significantly increased in the PAB group than those in the control group (7.8±1.7 and 1.0±0.2%, P<0.01, 76.2±27.5 and 32.7±7.5 ng/ml, P<0.01. Notably, the degree of hepatic fibrosis significantly correlated a decrease in CO. Immunohistological analysis revealed that hepatic stellate cells were markedly activated in hypoxic areas, and HIF-1α positive hepatic cells were increased in the PAB group. Furthermore, by real-time PCR analyses, transcripts of profibrotic and fibrotic factors (TGF-β1, CTGF, procollargen I, procollargen III, MMP 2, MMP 9, TIMP 1, TIMP 2 were significantly increased in the PAB group. In addition, western blot analyses revealed that the protein level of HIF-1α was significantly increased in the PAB group than that in the control group (2.31±0.84 and 1.0±0.18 arbitrary units, P<0.05.Our study demonstrated that low CO and tissue hypoxia were responsible for hepatic fibrosis in right failure heart model rats.

    To determine the association of gallbladder (GB) abnormalities on ultrasonography (US) of patients with acute hepatitis A with demographic, clinical, and biochemical factors, and with other US findings. This retrospective study was approved by our institutional review board, which waived the requirement for informed consent. We retrospectively evaluated 152 consecutive patients with acute hepatitis A who underwent US. The diagnosis of acute hepatitis A was made during acute illness by demonstrating anti- HAV of the IgM class. US images were reviewed simultaneously by two abdominal radiologists and a consensus was reached for GB wall thickening, GB collapse, lymphadenopathy, and hepatic echogenicity. The associations between demographic, clinical, biochemical, and US findings and GB wall thickening or collapse were then assessed. GB wall thickening was present in 123 (81%) and GB collapse in 96 (63%) of the 152 patients. Total bilirubin level and GB collapse differed significantly (p < 0.05) between patients with and without GB wall thickening. Gender ratio, total and peak total bilirubin level, and GB wall thickness differed significantly (p < 0.05) between patients with and without GB collapse. Multivariate analysis showed that GB wall thickening was associated with GB collapse and vice versa. GB wall thickening and GB collapse are common US abnormalities associated with each other in patients with acute hepatitis A. However, GB wall thickening or collapse is not associated with any demographic, clinical, or biochemical factors, or with other US findings, in patients with acute hepatitis A.

    Ammonia-induced mitochondrial dysfunction and energy crisis is known as a critical consequence of hepatic encephalopathy (HE). Hence, mitochondria are potential targets of therapy in HE. The current investigation was designed to evaluate the role of taurine treatment on the brain and liver mitochondrial function in a rat model of hepatic encephalopathy and hyperammonemia. The animals received thioacetamide (400mg/kg, i.p, for three consecutive days at 24-h intervals) as a model of acute liver failure and hyperammonemia. Several biochemical parameters were investigated in the serum, while the animals' cognitive function and locomotor activity were monitored. Mitochondria was isolated from the rats' brain and liver and several indices were assessed in isolated mitochondria. Liver failure led to cognitive dysfunction and impairment in locomotor activity in the rats. Plasma and brain ammonia was high and serum markers of liver injury were drastically elevated in the thioacetamide-treated group. An assessment of brain and liver mitochondrial function in the thioacetamide-treated animals revealed an inhibition of succinate dehydrogenase activity (SDA), collapsed mitochondrial membrane potential, mitochondrial swelling, and increased reactive oxygen species (ROS). Furthermore, a significant decrease in mitochondrial ATP was detected in the brain and liver mitochondria isolated from thioacetamide-treated animals. Taurine treatment (250, 500, and 1000mg/kg) decreased mitochondrial swelling, ROS, and LPO. Moreover, the administration of this amino acid restored brain and liver mitochondrial ATP. These data suggest taurine to be a potential protective agent with therapeutic capability against hepatic encephalopathy and hyperammonemia-induced mitochondrial dysfunction and energy crisis.

    BACKGROUND: Transplantation of mesenchymal stem cells (MSCs) has been regarded as a potential treatment for acute liver failure (ALF), but the optimal route was unknown. The present study aimed to explore the most effective MSCs trans-plantation route in a swine ALF model. METHODS: The swine ALF model induced by intravenous injection of D-Gal was treated by the transplantation of swine MSCs through four routes including intraportal injection (InP group), hepatic intra-arterial injection (AH group), pe-ripheral intravenous injection (PV group) and intrahepatic injection (IH group). The living conditions and survival time were recorded. Blood samples before and after MSCs trans-plantation were collected for the analysis of hepatic function. The histology of liver injury was interpreted and scored in terminal samples. Hepatic apoptosis was detected by TUNEL assay. Apoptosis and proliferation related protein expressions including cleaved caspase-3, survivin, AKT, phospho-AKT (Ser473), ERK and phospho-ERK (Tyr204) were analyzed by Western blotting. RESULTS: The average survival time of each group was 10.7 ± 1.6 days (InP), 6.0±0.9 days (AH), 4.7±1.4 days (PV), 4.3± 0.8 days (IH), respectively, when compared with the average survival time of 3.8±0.8 days in the D-Gal group. The sur-vival rates between the InP group and D-Gal group revealed a statistically signiifcant difference (P CONCLUSIONS: Intraportal injection was superior to other pathways for MSC transplantation. Intraportal MSC trans-plantation could improve liver function, inhibit apoptosis and prolong the survival time of swine with ALF. The transplanted MSCs may participate in liver regeneration via promoting cell proliferation and suppressing apoptosis during the initial stage of ALF.

    Acute renal failure (ARF) is a common complication in critically ill patients, with ARF requiring renal replacement therapy (RRT) developing in approximately 5 to 10% of intensive care unit (ICU) patients. Epidemiological studies have demonstrated that ARF is an independent risk factor for mortality. Interventions to prevent the development of ARF are currently limited to a small number of settings, primarily radiocontrast nephropathy and rhabdomyolysis. There are no effective pharmacological agents for the treatment of established ARF. Renal replacement therapy remains the primary treatment for patients with severe ARF; however, the data guiding selection of modality of RRT and the optimal timing of initiation and dose of therapy are inconclusive. This review focuses on the epidemiology and diagnostic approach to ARF in the ICU and summarizes our current understanding of therapeutic approaches including RRT.

    Benign goitres have the potential to reach massive sizes if neglected, but most have a protracted course that may or may not present with compressive symptoms. We report the case of a 57-year-old man who presented with a rapidly enlarging nodular goitre resulting in acute respiratory failure. Endotracheal intubation and emergency total thyroidectomy were performed, revealing massive thyroid nodules with minimal intrathoracic extension and tracheal erosion. Despite a course and clinical findings suggestive of malignant disease, histopathology was consistent with a benign multinodular goitre. Several cases of benign goitres necessitating endotracheal intubation have been reported. Airway compromise was attributed to a significant intrathoracic component, or inciting events such as thyroid haemorrhage, pregnancy, radioiodine uptake or major surgery. Obstructive symptoms may not correlate well with objective measures of upper airway obstruction such as radiographs or flow volume loops.

    Hashimoto's thyroiditis is the commonest form of autoimmune thyroiditis in the world. It occurs most frequently in women (female/male ratio, 6:1) in the age group between 30 and 60 years. Here we report the case of a 38-year-old Caucasian man who presented with a few days' history of upper limb paresthesias, widespread joint and muscle pain, and headaches. Laboratory findings showed increased CPK, myoglobin and plasma creatinine levels with acute renal failure. Low free T3 and T4 values associated with a high TSH value, the presence of antithyroid globulin and peroxidase autoantibodies pointed to a diagnosis of hypothyroidism with Hashimoto's thyroiditis. Treatment with levothyroxine was initiated and within 2 months normalization of renal function, myoglobin, CPK and thyroid hormone levels was observed.

    Full Text Available The powder of henna plant (Lawsonia inermis Linn. is extensively used as a decorative skin paint for nail coloring and as a hair dye. Most reports of henna toxicity have been attributed to adding a synthetic dye para-phenylenediamine (PPD. PPD is marketed as black henna added to natural henna to accentuate the dark color and shorten the application time. PPD toxicity is well known and extensively reported in medical literature. We report a case of a young Saudi male who presented with characteristic features of acute renal failure and intravascular hemolysis following ingestion of henna mixture. Management of PPD poisoning is only suppor-tive and helpful only if instituted early. Diagnosis requires a high degree of clinical suspicion, as the clinical features are quite distinctive.

    AIM: To analyze the related indices about the prognosesof chronic liver failure caused by hepatitis virus.METHODS: Retrospectively reviewed 320 cases of chronic liver failure caused by hepatitis viruses. An improved group and an ineffective group (IG) were made to compare and analyze their clinical manifestations, laboratory examination indices and complications. Logistic regression was also carried out. RESULTS: There were significant differences (P<0.05) between the improved group and the IG upon such indices as age, bilirubin, prothrombin time, albumin, alpha fetoprotein, the size of liver and complications (P<0.05). The regression formula was as follows: P = 1/(1+e-y)(y= 1.7262-0.0948X1+2.9846X2+0.6992X3+ 1.6019X4+2.0398X5). (Note: X1-Prothrombin activity; X2-digestive tract hemorrhage; X3-hepatic encephalopathy; X4-hepatorenal syndrome; X5-pulmonary infection.).CONCLUSION: Laboratory examination such as bilirubin, prothrombin time and alpha fetoprotein can be regarded as indices of the prognoses of chronic liver failure caused by hepatitis. Moreover, the regression equation can evaluate prognoses more comprehensively and direct our treatments.

    Chronic heart failure poses an enormous health care burden to the United States and other developed countries. Acute decompensated heart failure (ADHF) accounts for nearly half of the morbidity and expense of treating this disease. Most patients presenting with ADHF have symptomatic vascular congestion. Diuretics, especially loop diuretics, are the primary pharmacologic intervention used in this population. Despite their widespread use, scant data from randomized clinical trials are available to guide therapeutic choices. In addition, data from several large registries examining weight loss during hospitalization for ADHF suggest that efficacy with diuretic treatment is far from universal. Aggressive diuresis carries a significant risk of electrolyte and volume depletion, with subsequent arrhythmias, hypotension, and worsening renal function. These complications often translate into worse prognosis. Diuretic regimens used to treat ADHF must be individualized based on general knowledge of potency and pharmacokinetic and pharmacodynamic considerations. This article summarizes older and more recent literature to provide a framework for making rational treatment choices in this difficult patient population.

  12. Acute hepatitis C: changing epidemiology and association with HIV infection.

    Brejt, Nick; Gilleece, Yvonne; Fisher, Martin

    2007-03-01

    Over the past 6 to 7 years an increasing incidence of acute hepatitis C virus (AHCV) has been fuelled by two different changing epidemics: (1) a new resurgence of AHCV amongst intravenous drug users (IVDU); and (2) presumed sexually transmitted AHCV amongst predominantly HIV-positive men who have sex with men (MSM). Increasing incidence amongst IVDUs is likely to be a consequence of changing injecting behaviour, possibly related to changes in perception of HIV as well as HCV risk and consequences. Increasing incidence amongst MSM is likely to be a consequence of changing sexual practices, for example number of sexual partners and type of sexual behaviour, as well as increasing availability of recreational drugs associated with sexual risk-taking, and wider availability of casual sexual partners via the internet or sex-on-premises venues. It remains unclear whether the current outbreaks in MSM, predominantly seen in HIV-positive individuals, reflect a predisposition to AHCV secondary to HIV status per se, or whether this reflects differences in behaviour amongst HIV-positive versus HIV-negative MSM, or potentially increased screening (either routine or secondary to abnormal liver function tests) in HIV-positive MSM. The majority of individuals with AHCV are asymptomatic and therefore routine screening of individuals in at-risk groups with abnormal liver function tests should be considered. Previous historical studies suggest that individuals with concomitant HIV infection are far less likely than those without to spontaneously clear HCV. It is currently recommended that such individuals acutely infected with HCV should undergo monitoring of HCV viral load levels to determine whether spontaneous clearance is likely or whether the opportunity for early treatment should be considered.

    Although hemangiomas are the most common vascular tumors of the liver in infancy, data regarding hypothyroidism and heart failure related to hepatic hemangiomas are limited. Here, we present a 15- day -old girl who presented with prolonged jaundice at the age of 15 days. Because her TSH level was found to be 74 μIU/mL, she was initially diagnosed with congenital hypothyroidism and L-Thyroxine replacement therapy was initiated. On follow-up examination performed two months later, it was observed that her TSH level was not suppressed and a mass was noticed in the right upper abdomen on physical examination. Abdominal ultrasonography revealed multiple masses with sizes of about 3-3,5 cm covering the whole liver. When evaluated with clinical and radiological appearance, oral methylprednisolone at a dose of 5 mg/kg/day and propranolol at a dose of 2 mg/kg were initiated with a diagnosis of hepatic hemagioma/hemangioendothelioma. Consumptive hypothyroidism due to hepatic hemangioma and congestive heart failure were considered in the patient who had findings of heart failure. The dose of L-Thyroxine was increased 2-fold. The patient received intensive care treatment for severe heart failure. Because his findings resolved, he was started to be followed up with propranolol, steroid and L-Thyroxine treatment.

    2006-01-01

    Intracranial hypertension is a major cause of morbidity and mortality of patients suffering from fulminant hepatic failure. The etiology of this intracranial hypertension is not fully determined, and is probably multifactorial, combining a cytotoxic brain edema due to the astrocytic accumulation of glutamine, and an increase in cerebral blood volume and cerebral blood flow, in part due to inflammation, to glutamine and to toxic products of the diseased liver. Validated methods to control intracranial hypertension in fulminant hepatic failure patients mainly include mannitol, hypertonic saline, indomethacin, thiopental, and hyperventilation.However all these measures are often not sufficient in absence of liver transplantation, the only curative treatment of intracranial hypertension in fulminant hepatic failure to date. Induced moderate hypothermia seems very promising in this setting, but has to be validated by a controlled, randomized study. Artificial liver support systems have been under investigation for many decades. The bioartificial liver, based on both detoxification and swine liver cells, has shown some efficacy on reduction of intracranial pressure but did not show survival benefit in a controlled, randomized study.The Molecular Adsorbents Recirculating System has shown some efficacy in decreasing intracranial pressure in an animal model of liver failure, but has still to be evaluated in a phase Ⅲ trial.

    Full Text Available BACKGROUND: Acute-on-chronic liver failure (ACLF is an acute deterioration of established liver disease. Blocking the TNF (tumor necrosis factor/TNFR (tumor necrosis factor receptor 1 pathway may reduce hepatocyte apoptosis/necrosis, and subsequently decrease mortality during development of ACLF. We demonstrated that a long-acting TNF antagonist (soluble TNF receptor: IgG Fc [sTNFR:IgG-Fc] prevented/reduced development of acute liver failure by blocking the TNF/TNFR1 (TNFRp55 pathway. However, it is still unclear if sTNFR:IgG-Fc can inhibit hepatocyte damage during development of ACLF. METHODOLOGY: Chronic liver disease (liver fibrosis/cirrhosis was induced in Wistar rats by repeatedly challenging with human serum albumin (HSA, and confirmed by histopathology. ACLF was induced with D-galactosamine (D-GalN/lipopolysaccharide (LPS i.p. in the rats with chronic liver disease. Serum and liver were collected for biochemical, pathological and molecular biological examinations. PRINCIPAL FINDINGS: Reduced mortality was observed in sTNFR:IgG-Fc treated ACLF rats, consistent with reduced interleukin (IL-6 levels in serum and liver, as well as reduced hepatic caspase-3 activity, compared to that of mock treated group. Reduced hepatic damage was confirmed with histopathology in the sTNFR:IgG-Fc treated group, which is consistent with reduced Bcl-2 and Bax, at mRNA and protein levels, but increased hepatocyte proliferation (PCNA. This is also supported by the findings that caspase-3 production was up-regulated significantly in ACLF group compared to the mock treated group. Moreover, up-regulated caspase-3 was inhibited following sTNFR:IgG-Fc treatment. Finally, there was up-regulation of hepatic IL-22R in sTNFR:IgG-Fc treated ACLF rats. CONCLUSIONS: sTNFR:IgG-Fc improved survival rate during development of ACLF via ameliorating liver injury with a potential therapeutic value.

    Full Text Available El espectro clínico de la infección aguda por el virus de la hepatitis B es muy amplio, con cuadros que van desde una hepatitis anictérica y subclínica a una hepatitis ictérica aguda grave e incluso, en algunos casos, a una hepatitis fulminante. El diagnóstico depende en gran medida del grado de sospecha clínica de la hepatitis, estableciéndose el origen etiológico por el virus B mediante el estudio de marcadores serológicos y/o DNA en sangre. Aunque en la mayor parte de los casos la evolución de la hepatitis aguda por virus B es favorable, con resolución espontánea de la clínica en 4-8 semanas, no es infrecuente en ciertos casos, sobre todo en la infancia, la progresión a hepatitis crónica. No existe ningún tratamiento específico para la infección aguda por virus B que reduzca su gravedad o prevenga su evolución a hepatitis crónica. Se recomienda, no obstante, el reposo relativo, y la administración de una dieta hipercalórica. En las hepatitis agudas graves debe indicarse ingreso hospitalario; en casos de hepatitis fulminante ingreso en UCI para monitorización intensiva y valoración de trasplante hepático si no se produce mejoría espontánea. En el presente artículo se revisa, de forma breve y esquemática, la clínica, el diagnóstico, el pronóstico y el tratamiento de la infección aguda por el virus de la hepatitis B.The clinical spectrum of acute hepatitis B virus infection is very broad, with clinical manifestations that range from anicteric and sub-clinical hepatitis to severe acute icteric hepatitis and even, in some cases, to fulminant hepatitis. Diagnosis depends to a large extent on the degree of clinical suspicion of hepatitis, establishing the aetiological origin of the B virus through the study of serological markers and/or DNA in the blood. Although in the majority of cases there is a favourable evolution of acute hepatitis B virus infection, with spontaneous resolution of the clinical manifestations

    A 52-year-old Japanese woman admitted to our hospital for the treatment of liver dysfunction due to an undetermined cause developed disorientation on the 58th hospital day and was diagnosed with late-onset liver failure. Abdominal ultrasound examinations were performed several times from the admission. Before the disorientation appeared, the results of the examinations revealed that the portal flow decreased, after which the hepatic arterial flow increased and the degree of liver stiffness became elevated. Although the pathophysiology of these changes remains unclear, hemodynamic changes and elevation of liver stiffness might be predictive markers of severe liver tissue damage.

    Objectives This study evaluated the Model for End-Stage Liver Disease (MELD) score and its modified versions, which are established measures of liver dysfunction, as a tool to assess heart transplantation (HTx) urgency in ambulatory patients with heart failure. Background Liver abnormalities have a prognostic impact on the outcome of patients with advanced heart failure. Methods We retrospectively evaluated 343 patients undergoing HTx evaluation between 2005 and 2009. The prognostic effectiveness of MELD and 2 modifications (MELDNa [includes serum sodium levels] and MELD-XI [does not include international normalized ratio]) for endpoint events, defined as death/HTx/ventricular assist device requirement, was evaluated in our cohort and in subgroups of patients on and off oral anticoagulation. Results The MELD and MELDNa scores were excellent predictors for 1-year endpoint events (areas under the curve: 0.71 and 0.73, respectively). High scores (>12) were strongly associated with poor survival at 1 year (MELD 69.3% vs. 90.4% [p < 0.0001]; MELDNa 70.4% vs. 96.9% [p < 0.0001]). Increased scores were associated with increased risk for HTx (hazard ratio: 1.10 [95% confidence interval: 1.06 to 1.14]; p < 0.0001 for both scores), which was independent of other known risk factors (MELD p = 0.0055; MELDNa p = 0.0083). Anticoagulant use was associated with poor survival at 1 year (73.7% vs. 86.4%; p = 0.0118), and the statistical significance of MELD/MELDNa was higher in patients not receiving oral anticoagulation therapy. MELD-XI was a fair but limited predictor of the endpoint events in patients receiving oral anticoagulation therapy. Conclusions Assessment of liver dysfunction according to the MELD scoring system provides additional risk information in ambulatory patients with heart failure. PMID:23563127

    AIM: To investigate the effect of N-acetyl cysteine (NAC)on acute viral hepatitis (AVH).METHODS: We administered 200 mg oral NAC three times daily (600 mg/day) to the study group and placebo capsules to the control group. All patients were hospitalized and diagnosed as AVH. Blood total and direct bilirubin, ALT, AST,alkaline phosphatese, albumin and globulin levels of each patient were measured twice weekly until total bilirubin level dropped under 2 mg/dl, ALT level under 100 U/L, follow up was continued and then the patients were discharged.RESULTS: A total of 41(13 female and 28 male) AVH patients were included in our study. The period for normalization of ALT and total bilirubin in the study group was 19.7±6.9 days and 13.7±8.5 days respectively. In the control group it was 20.4±6.5 days and 16.9±7.8 days respectively (P>0.05).CONCLUSION: NAC administration effected neither the time necessary for normalization of ALT and total bilirubin values nor duration of hospitalization, so we could not suggest NAC for the treatment of icteric AVH cases. However, our results have shown that this drug is not harmful to patients with AVH.

    Although hepatic encephalopathy (HE) on the background of acute on chronic liver failure (ACLF) is associated with high mortality rates, it is unknown whether this is due to increased blood-brain barrier permeability. Specific gravity of cerebrospinal fluid measured by CT is able to estimate blood-cerebrospinal fluid-barrier permeability. This study aimed to assess cerebrospinal fluid specific gravity in acutely decompensated cirrhosis and to compare it in patients with or without ACLF and with or without hepatic encephalopathy. We identified all the patients admitted for acute decompensation of cirrhosis who underwent a brain CT-scan. Those patients could present acute decompensation with or without ACLF. The presence of hepatic encephalopathy was noted. They were compared to a group of stable cirrhotic patients and healthy controls. Quantitative brain CT analysis used the Brainview software that gives the weight, the volume and the specific gravity of each determined brain regions. Results are given as median and interquartile ranges and as relative variation compared to the control/baseline group. 36 patients presented an acute decompensation of cirrhosis. Among them, 25 presented with ACLF and 11 without ACLF; 20 presented with hepatic encephalopathy grade ≥ 2. They were compared to 31 stable cirrhosis patients and 61 healthy controls. Cirrhotic patients had increased cerebrospinal fluid specific gravity (CSF-SG) compared to healthy controls (+0.4 %, p gravity did not differ between different brain regions according to the presence or absence of either ACLF or HE. In patients with acute decompensation of cirrhosis, and those with ACLF, CSF specific gravity is modified compared to both stable cirrhotic patients and healthy controls. This pattern is observed even in the absence of hepatic encephalopathy suggesting that blood-CSF barrier impairment is manifest even in absence of overt hepatic encephalopathy.

    Autoimmune hepatitis is a disease of the hepatic parenchyma that can present in acute or chronic forms. In common with many autoimmune diseases, autoimmune hepatitis is associated with non-organ-specific antibodies in the context of hepatic autoimmunity. This dichotomy has made definition of a unifying hypothesis in the pathophysiology of the disease difficult, although data from the past 8 years have drawn attention to the role of regulatory T cells. Several triggers have been identified, and the disease arises in genetically susceptible individuals. Clinical and biochemical remission is achievable in up to 85% of cases. For the remaining patients, alternative immunosuppression strategies are an option. Liver transplantation provides an excellent outcome for patients with acute liver failure or complications of end-stage liver disease, including hepatocellular carcinoma. Variant or overlapping syndromes are worthy of consideration when unexpected disease features arise.

    Full Text Available Abstract Background Hepatitis A virus is an infection of liver; it is hyperendemic in vast areas of the world including India. In most cases it causes an acute self limited illness but rarely fulminant. There is growing concern about change in pattern from asymptomatic childhood infection to an increased incidence of symptomatic disease in the adult population. Objective In-depth analysis of immunological, viral quantification and genotype of acute and fulminant hepatitis A virus. Methods Serum samples obtained from 1009 cases of suspected acute viral hepatitis was employed for different biochemical and serological examination. RNA was extracted from blood serum, reverse transcribed into cDNA and amplified using nested PCR for viral quantification, sequencing and genotyping. Immunological cell count from freshly collected whole blood was carried out by fluorescence activated cell sorter. Results Fulminant hepatitis A was mostly detected with other hepatic viruses. CD8+ T cells count increases in fulminant hepatitis to a significantly high level (P = 0.005 compared to normal healthy control. The immunological helper/suppressor (CD4+/CD8+ ratio of fulminant hepatitis was significantly lower compared to acute cases. The serologically positive patients were confirmed by RT-PCR and total of 72 (69.2% were quantified and sequenced. The average quantitative viral load of fulminant cases was significantly higher (P Conclusions Immunological factors in combination with viral load defines the severity of the fulminant hepatitis A. Phylogenetic analysis of acute and fulminant hepatitis A confirmed genotypes IIIA as predominant against IA with no preference of disease severity.

    Full Text Available Hepatic encephalopathy can be a serious complication of acute liver failure and chronic liver diseases, predominantly liver cirrhosis. Hyperammonemia plays the most important role in the pathogenesis of hepatic encephalopathy. The brain-blood barrier disturbances, changes in neurotransmission, neuroinflammation, oxidative stress, GABA-ergic or benzodiazepine pathway abnormalities, manganese neurotoxicity, brain energetic disturbances, and brain blood flow abnormalities are considered to be involved in the development of hepatic encephalopathy. The influence of small intestine bacterial overgrowth (SIBO on the induction of minimal hepatic encephalopathy is recently emphasized. The aim of this paper is to present the current views on the pathogenesis of hepatic encephalopathy.

    Full Text Available Background: Located in the south western part of Saudi Arabia, the Gizan region is largely a rural community in which hepatitis B and chronic liver disease including hepatocellular carcinoma are highly prevalent. Aim of study: To determine the relative frequencies of acute hepatitis A, B, C and E in acute viral hepatitis in an area of hyperendemic hepatitis B infection. Methods and materials: In a prospective study 246 consecutive patients (179 males and 67 females diagnosed in a 2-year period were tested for markers of Hepatitis A virus (HAV, hepatitis B virus (HBV, hepatitis C (HCV and hepatitis E virus (HEV. Results: Of the patients tested, 131 (53.3% were children (< 10 years, and 42 (17% were 11 - 20 years in age. Ig M anti -HAV, IgM anti-HBV, anti- HCV and IgM anti-HEV were positive in 37%, 19.1%, 3.7% and 13.7% respectively. Markers of these viruses were absent in 24.4%. Among 131 children (< 10 years the commonest cause of AVH was HAV occurring in 57.3% of the cases. In adults (> 21 years HBV was found in 35.6% and IgM anti -HAV was detected in only 6.8%. In contrast to the age- related decline in the frequency of acute HA, the proportion of acute HE were similar in all age groups (13.7% in children, 16.7% in adolescents and 11.0% in adults. Conclusion: The study indicated that HAV is still a common cause of AVH particularly among children in Gizan. Acute 1-113 had a low occurrence among the children, evidently as a consequence of the integration of HB vaccine into the Saudi Arabian national EPI, 10 years ago. With the availability of combined HB and HA vaccines, It should be possible to graft the vaccination against HAV on to the existing program in Saudi Arabia. Affecting 13.4% of the group studied, sporadic HEV constitute a significant cause of AVH in this population. Until HEV vaccine becomes widely available, its prevention would be mainly by the improvement of socio - economic and hygienic standards of the population.

    BACKGROUND Failure of remission-induction therapy is a rare but highly adverse event in children and adolescents with acute lymphoblastic leukemia (ALL). METHODS We identified induction failure, defined by the persistence of leukemic blasts in blood, bone marrow, or any extramedullary site after 4 to 6 weeks of remission-induction therapy, in 1041 of 44,017 patients (2.4%) 0 to 18 years of age with newly diagnosed ALL who were treated by a total of 14 cooperative study groups between 1985 and 2000. We analyzed the relationships among disease characteristics, treatments administered, and outcomes in these patients. RESULTS Patients with induction failure frequently presented with high-risk features, including older age, high leukocyte count, leukemia with a T-cell phenotype, the Philadelphia chromosome, and 11q23 rearrangement. With a median follow-up period of 8.3 years (range, 1.5 to 22.1), the 10-year survival rate (±SE) was estimated at only 32±1%. An age of 10 years or older, T-cell leukemia, the presence of an 11q23 rearrangement, and 25% or more blasts in the bone marrow at the end of induction therapy were associated with a particularly poor outcome. High hyperdiploidy (a modal chromosome number >50) and an age of 1 to 5 years were associated with a favorable outcome in patients with precursor B-cell leukemia. Allogeneic stem-cell transplantation from matched, related donors was associated with improved outcomes in T-cell leukemia. Children younger than 6 years of age with precursor B-cell leukemia and no adverse genetic features had a 10-year survival rate of 72±5% when treated with chemotherapy only. CONCLUSIONS Pediatric ALL with induction failure is highly heterogeneous. Patients who have T-cell leukemia appear to have a better outcome with allogeneic stem-cell transplantation than with chemotherapy, whereas patients who have precursor B-cell leukemia without other adverse features appear to have a better outcome with chemotherapy.

    Full Text Available Acute renal failure (ARF is a rare complication of acute pyelonephritis in adult immunocompetent patients. Recovery of renal function usually occurs if antibiotics are promptly initiated. However, long-term consequences of renal scarring due to acute pyelonephritis are probably underestimated, and some patients present with prolonged renal failure despite adequate antibiotic therapy. We report two cases of severe ARF complicating bacterial pyelonephritis successfully treated with corticosteroids in association with conventional antibiotics.

    Primary malignant tumors of the heart, specifically cardiac sarcomas, are rare and mainly diagnosed at autopsy. Acute Budd-Chiari syndrome is a recognized cause of acute liver failure and has been associated with several rare cardiac tumors: atrial myxoma, caval rhabdomyosarcoma, and primary cardiac adenocarcinoma. We present the first case of a fatal, highly differentiated cardiac synovial sarcoma that presented as acute liver failure from Budd-Chiari syndrome.

    Unexpected severe cholestasis is part of the presentation in some neonates with hemolytic anemia but is usually self-resolving. Here we report the case of a neonate with pyruvate kinase deficiency (PKD) who presented severe hemolytic anemia at birth, characterized by a rapidly progressive and severe cholestasis with normal γ-glutamyl transpeptidase level associated with hepatic failure. After an extensive investigation to rule out contributing conditions explaining the severity of this patient's clinical presentation, PKD has remained the sole identified etiology. The patient abruptly died of sepsis at 3 months of age before a planned splenectomy and ongoing evaluation for liver transplantation. To the best of our knowledge, only a few similar cases of severe neonatal presentation of PKD complicated with severe hepatic failure and cholestasis have been reported.

    Commercial dietary supplements are marketed as a panacea for the morbidly obese seeking sustainable weight-loss. Unfortunately, many claims cited by supplements are unsupported and inadequately regulated. Most concerning, however, are the associated harmful side effects, often unrecognized by consumers. Garcinia cambogia extract and Garcinia cambogia containing products are some of the most popular dietary supplements currently marketed for weight loss. Here, we report the first known case of fulminant hepatic failure associated with this dietary supplement. One active ingredient in this supplement is hydroxycitric acid, an active ingredient also found in weight-loss supplements banned by the Food and Drug Administration in 2009 for hepatotoxicity. Heightened awareness of the dangers of dietary supplements such as Garcinia cambogia is imperative to prevent hepatoxicity and potential fulminant hepatic failure in additional patients.

    1986-12-01

    Full Text Available As few reports on the prevalence of each type of viral hepatitis have been published in our country, we studied 154 patients with acute viral hepatitis consecutively seen at the Liver Unit from November 1980 to November 1984. The frequency of hepatitis A, B and non-A, non-B was 52.6%, 27.3% and 20.1% respectively. Greater frequency in young people, previous contact with infected patients and ingestion of suspected foods were the predominant epidemiological features in the hepatitis A group. Hepatitis B was characterized by the parenteral, non-transfusional exposure, previous contact and a high occurence in health-care workers. A history of blood transfusion was a significant finding in the hepatitis non-A, non-B group. Finally, the routes of transmission were unknown in 30-40% of the three groups of patients.

    Hepatitis C therapy in the era of the newer direct-acting antiviral agents has radically changed our treatment schemes by achieving very high rates of sustained virological response. However, treatment with direct antiviral agents fails in a subgroup of patients. This group of so-called difficult-to-treat individuals is the subject of this paper, which reviews the causes of virological failure, their clinical implications, and some final recommendations.

    AIM: To investigate the pathogenic role of cathepsin B and the protective effect of a cathepsin B inhibitor (CA-074Me) in fulminant hepatic failure in mice.METHODS: LPS/D-Gal N was injected into mice of the model group to induce fulminant hepatic failure;the protected group was administered CA-074me for 30 min before LPS/D-Gal N treatment; the normal group was given isochoric physiologic saline. Liver tissue histopathology was determined with HE at 2,4, 6 and 8 h after Lps/D-Gal injection. Hepatocyte apoptosis was examined by TUNEL method. The expression of cathepsin B in liver tissues was investigated by immunohistochemistry, Western blot and RT-PCR.RESULTS: Compared with the normal group, massive typical hepatocyte apoptosis occurred in the model group; the number of apoptotic cells reached a maximum 6 h after injection. The apoptosis index (AI) in the protected group was clearly reduced (30.4$$$$markedly increased in drug-treated mice compared with the normal group ( P < 0.01). Incubation with LPS/D-Gal N at selected time points resulted in a timedependent increase in cathepsin B activity, and reached a maximum by 8 h. The expression of cathepsin B was significantly decreased in the protected group ( P <0.01).CONCLUSION: Cathepsin B plays an essential role in the pathogenesis of fulminant hepatic failure, and the cathepsin B inhibitor CA-074me can attenuate apoptosis and liver injury.

    Objective To identify the risk factors associated with progression of acute -on - chronic liver failure (ACLF) occurring in patients with chronic hepatitis B virus (HBV) infection (CHB). Methods The clinical, demographic, treatment and outcome data of 180 ACLF patients with concomitant CHB managed in our hospital between June 2009 and September 2012 were retrospectively reviewed. Clinical data, taken at baseline, included markers of inflammation/infection (white blood cell (WBC) count) , coagulation (prothrombin time (PT) and prothrombin activity (PTA)) , and liver function (alanine aminotransferase ( ALT) , aspartate aminotransferase (AST) , total bilirubin (TBil) , direct bilirubin ( DBil) , choninesterase ( CHE) , albumin ( Alb) , globulin ( Glb) , total cholesterol (TC) , and ammonia). In - hospital treatments included supplementation with traditional Chinese medicine - based therapies, such as Tuihuang decoction and detoxification enema. The primary outcome was survival during hospitalization. The patients were grouped for analysis according to ACLF stage (early, n = 93; mid, n =61 ; late, n =26) and the risk factors associated with each stage were identified by using univariate (log -rank test) and multiva-riate (Cox's test) regression analyses. The association of risk factors with patient survival was assessed by Kaplan - Meier curve analysis. Results The three ACLF groups showed significantly different amounts of leukocytes, with the late ACLF group showing the highest WBC. The late ACLF group also showed significantly lower Glb and TC. There was a trend in reduced cumulative survival rate and shorter time to death that significantly corresponded to progressive stages of ACLF ( early ACLF > mid ACLF > late ACLF; all P <0. 001). One - hundred -and - twenty - six (70. 0% ) of the patients died during their hospitalization, and multivariate regression analysis of this entire patient population identified absence of colonic enema, presence of hepatic

    Impaired renal function is associated with an increased risk for cardiovascular events and death, but the pathophysiology is poorly defined. The hypothesis that coronary blood flow regulation and distribution of ventricular blood flow could be compromised during acute renal failure (ARF) was tested. In two separate groups (n = 14 each) of dogs with ARF, (1) coronary autoregulation (pressure-flow relations), vascular reserve (reactive hyperemia), and myocardial blood flow distribution (microspheres) and (2) coronary vessel responses to intracoronary infusion of select endothelium-dependent and -independent vasodilators were evaluated. In addition, coronary pressure-flow relations and vascular reserve after inhibition of nitric oxide and prostaglandin release were evaluated. Under resting conditions, myocardial oxygen consumption increased in dogs with ARF compared with no renal failure (NRF; 11.8 +/- 9.2 versus 5.0 +/- 1.5 ml O(2)/min per 100 g; P = 0.01), and the autoregulatory break point of the coronary pressure-flow relation was shifted to higher diastolic coronary pressures (60 +/- 17 versus 52 +/- 8 mmHg in NRF; P = 0.003); the latter was shifted further rightward after inhibition of both nitric oxide and prostaglandin release. The endocardial/epicardial blood flow ratio was comparable for both groups, suggesting preserved ventricular distribution of blood flow. In dogs with ARF, coronary vascular conductance also was reduced (P = 0.001 versus NRF), but coronary zero-flow pressure was unchanged. Vessel reactivity to each endothelium-dependent/independent compound also was blunted significantly. In conclusion, under resting conditions, coronary vascular tone, reserve, and vessel reactivity are markedly diminished with ARF, suggesting impaired vascular function. Consequently, during ARF, small increases in myocardial oxygen demand would induce subendocardial ischemia as a result of a limited capacity to increase oxygen supply and thereby contribute to higher

    BACKGROUND:Acute-on-chronic liver failure (ACLF) is common in Bangladesh. Acute viral E hepatitis is sporadically encountered in this country each year, with a rising incidence in the rainy season. This study aimed to identify the etiology of ACLF in Bangladesh. METHODS:In this retrospective study, 69 ACLF patients were included. They presented to our department at the Bangabandhu Sheikh Mujib Medical University in Dhaka. History of diseases was recorded and appropriate investigations were conducted in all patients. RESULTS:Acute hepatitis E virus (HEV) infection was positive in 21.7% (15/69) of the patients, while 14.5%(10/69) had septicemia. Upper gastrointestinal tract hemorrhage was seen in 4.3% of the patients (3/69), while another 4.3% (3/69) had a positive history for alcohol or drugs. None of the patients tested positive for hepatitis A virus infection and no evidence of hepatitis B virus lfare was found in any patient. No speciifc cause for ACLF could be identiifed. CONCLUSIONS:Acute HEV infection is a leading cause of ACLF in Bangladesh. Many patients were thought to have decompensation of cirrhosis, but subsequently were recognized as having ACLF by a retrospective review according to the deifnition of the Asian Paciifc Association for the Study of the Liver Working Party Meeting on ACLF in New Delhi in early 2008.

    AIM: To investigate in children with acute hepatitis A.According to our knowledge, there are no data about the blood levels of malondialdehyde (MDA, an indicator of oxidative stress) and nonenzymic antioxidants in children with acute hepatitis A.METHODS: Whole blood MDA and reduced glutathione (GSH), serum β-carotene, retinol, vitamin E and vitamin C levels were studied in 19 (10 females, 9 males)children with acute hepatitis A and in 29 (13 females, 16males) healthy control subjects.RESULTS: There was a statistically significant difference between patients and controls for all parameters (P <0.05). Lipid peroxidation marker MDA was significantly elevated (P < 0.001), while antioxidants β-carotene,retinol and GSH were significantly decreased (all P <0.001) in patients compared to healthy subjects. In addition, α-tocopherol and ascorbic acid levels were significantly lower in patients when compared to age and sex matched controls (P < 0.05, P < 0.01, respectively).CONCLUSION: Our study shows that hepatitis A virus induces oxidative stress in childern with hepatitis A. This finding could be taken into consideration to improve the therapeutic approach in acute hepatitis A.

    BACKGROUND: Acute hepatic failure (AHF) is a devastating clinical syndrome with a high mortality rate. The outcome of AHF varies with etiology, but liver transplantation (LT) can significantly improve the prognosis and survival rate of such patients. This study aimed to detect the role of LT and artificial liver support systems (ALSS) for AHF patients and to analyze the etiology and outcome of patients with this disease. METHODS: A retrospective analysis was made of 48 consecutive patients with AHF who fulfilled the Kings College Criteria for LT at our center. We analyzed and compared the etiology, outcome, prognosis, and survival rates of patients between the transplantation (LT) group and the non-transplantation (N-LT) group. RESULTS: AHF was due to viral hepatitis in 25 patients (52.1%; hepatitis B virus in 22), drug or toxic reactions in 14 (29.2%; acetaminophen in 6), Wilson disease in 4 (8.3%), unknown reasons in 3 (6.3%), and miscellaneous conditions in 2 (4.2%). In the LT group, 36 patients (7 underwent living donor LT, and 29 cadaveric LT) had an average model for end-stage liver disease score (MELD) of 35.7. Twenty-eight patients survived with good graft function after a follow-up of 27.3± 4.5 months. During the waiting time, 6 patients were treated with ALSS and 2 of them died during hospitalization. The 30-day, 12-month, and 18-month survival rates were 77.8%, 72.2%, and 66.7%, respectively. In the N-LT group, 12 patients had an average MELD score of 34.5. Four patients were treated with ALSS and all died during hospitalization. The 90-day and 1-year survival rates were only 16.7% and 8.3%, respectively. CONCLUSIONS: Hepatitis is the most prominent cause of AHF at our center. Most patients with AHF, who fulfill the Kings College Criteria for LT, did not survive longer without LT. ALSS did not improve the prognosis of AHF patients, but may extend the waiting time for a donor. Currently, LT is still the most effective way to improve the prognosis

    The purpose of this study was to evaluate the effects and outcome of continuous-flow left ventricular assist device (cf-LVAD) therapy in patients with preoperative acute hepatic failure. The study design was a retrospective review of prospectively collected data. Included were 42 patients who underwent cf-LVAD implantation (64.3% HeartMate II, 35.7% HeartWare) between July 2007 and May 2013 with preoperative hepatic failure defined as elevation of greater than or equal to two liver function parameters above twice the upper normal range. Mean patient age was 35 ± 12.5 years, comprising 23.8% females. Dilated cardiomyopathy was present in 92.9% of patients (left ventricular ejection fraction 17.3 ± 5.9%). Mean support duration was 511 ± 512 days (range: 2-1996 days). Mean preoperative laboratory parameters for blood urea nitrogen, serum creatinine, total bilirubin, and alanine aminotransferase were 9.5 ± 5.4 mg/dL, 110.3 ± 42.8 μmol/L, 51.7 ± 38.3 mmol/L, and 242.1 ± 268.6 U/L, respectively. All parameters decreased significantly 1 month postoperatively. The mean preoperative modified Model for Endstage Liver Disease excluding international normalized ratio score was 16.03 ± 5.57, which improved significantly after cf-LVAD implantation to 10.62 ± 5.66 (P failure over the follow-up period. Patients with preexisting acute hepatic failure are reasonable candidates for cf-LVAD implantation, with excellent rates of recovery and survival, suggesting that cf-LVAD therapy should not be denied to patients merely on grounds of "preoperative elevated liver enzymes/hepatopathy."

    Full Text Available Adult coeliac disease commonly presents without classical symptoms as chronic diarrhea and weight loss. We describe the case of a 31-year-old woman with persistent life-threatening hypokalemia, acute renal failure, and acute quadriplegia due to diarrhea that had continued for one month. Although there are cases of coeliac disease diagnosed with hypokalemic rhabdomyolysis in the literature, none of the cases developed acute renal failure. This is the first case in the literature diagnosed with acute renal failure due to hypokalemic rhabdomyolysis as a presentation of coeliac disease. In acute renal failure cases that present with hypokalemic rhabdomyolysis due to severe diarrhea, coeliac disease should be considered as a differential diagnosis despite the negative antigliadin IgA antibody.

    This study investigates the effects of lysine-induced acute renal failure. Female dogs received a lysine hydrochloride (lysine) of 4500 mg/kg/day (3.75 ml/kg/hr) for 3 consecutive days. The dogs were observed for clinical signs. Body weights were recorded, food consumption and water consumption calculated, and urinalysis and blood biochemistry were performed daily. Plasma samples for amino acid determinations were obtained from all dogs, which were necropsied on Day 3. Histopathological examinations were done on all test animals. Compound-related findings include the following. Blood biochemistry results showed increases in ammonia, blood urea nitrogen, blood urea nitrogen/creatinine ratio, and creatinine. Urinary changes consisted of increases in urine volume, total protein, albumin, gamma-glutamyl transpeptidase, and N-acetyl-beta-D-glucosaminidase. In addition, macroscopic findings consisted of pale, congested capsule; microscopic findings consisted of hypertrophy of proximal convoluted tubule (mainly S1 segment), and degeneration/desquamation of urinary tubule (mainly S3 segment with hyaline casts) in the kidney. From these findings, it can be concluded that lysine is nephrotoxic in dogs. Nephrotoxicity of lysine may relate to direct tubular toxicity and to tubular obstruction.

    Each year, there are over one million hospitalizations for acute heart failure syndrome (AHFS) in the United States alone,with a similar number in Western Europe. These patients have very high short-term (2-6 months) mortality and readmission rates, while the healthcare system incurs substantial costs. Until recently, the clinical characteristics, management patterns, and outcomes of these patients have been poorly understood and, in consequence, risk stratification for these patients has not been well defined. Several risk prediction models that can accurately identify high-risk patients have been developed in the last year using data from clinical trials, large registries or administrative databases. Use of multi-variable risk models at the time of hospital admission or discharge offers better risk stratification and should be encouraged, as it allows for appropriate allocation of existing resources and development of clinical trials testing new treatment strategies for patients admitted with AHFS. The emerging observation that the prognosis for the ensuing three to six months may be obtained at presentation for AHFS has major implications for development of future therapies.

    Acute liver failure (ALF) can be complicated by lung dysfunction. The aim of this study was to test the hypothesis that inhibition of oxidative stress through iron chelation with desferrioxamine (DFX) attenuates pulmonary injury caused by ALF. 14 adult female domestic pigs were subjected to surgical devascularisation of the liver and were randomised to a study group (DFX group, n = 7), which received post-operative intravenous infusion of DFX (14.5 mg x kg(-1) x h(-1) for the first 6 h post-operatively and 2.4 mg x kg(-1) x h(-1) until completion of 24 h), and a control group (n = 7). Post-operative lung damage was evaluated by histological and bronchoalveolar lavage fluid (BALF) analysis. DFX resulted in reduced BALF protein levels and tissue phospholipase (PL)A(2) activity. Plasma malondialdehyde and BALF nitrate and nitrite concentrations were lower, while catalase activity in the lung was higher after DFX treatment. PLA(2), platelet-activating factor acetylhydrolase and total cell counts in BALF did not differ between groups. Histological examination revealed reduced alveolar collapse, pneumonocyte necrosis and total lung injury in the DFX-treated animals. DFX reduced systemic and pulmonary oxidative stress during ALF. The limited activity of PLA(2) and the attenuation of pneumonocyte necrosis could represent beneficial mechanisms by which DFX improves alveolar-capillary membrane permeability and prevents alveolar space collapse.

    Full Text Available Aim: The aim of this study was to investigate the etiological factors, clinical progression and management of acute renal failure (ARF in hospitalized children. Materials and Method: Medical records of 63 patients aged between 1 month and 18 years who were hospitalized at Uludag University, Department of Pediatrics or at various intensive care departments of the faculty and diagnosed with ARF between January 2005 and August 2006 were retrospectively analyzed. Results: Forty two of study patients were male and 21 were female. Mean age was 5.4±5.3 years. ARF was found in 4.9% of all hospitalized patients. Sepsis was the most frequent etiological factor with a ratio of 23.8%; which was followed by gastroenteritis (19.1%, tumor lysis syndrome (17.4% and cardiac surgery (15.9%. Oliguria, sepsis, hyperkalemia, acidosis and dialysis were found to be associated with increased mortality (p<0.05. The mortality rate in the study population was 49.2%.Conclusion: Dialysis and mechanical ventilation was found to be associated with a poor outcome in our patients.

    Full Text Available Abstract Background Norway is classified as a low prevalence country for hepatitis B virus infection. Vaccination is only recommended for risk groups (intravenous drug users (IDUs, Men who have Sex with Men (MSM, immigrants and contacts of known carriers. We describe the epidemiology of reported cases of hepatitis B in Norway, during the years 1992-2009 in order to assess the validity of current risk groups and recommend preventive measures. Methods We used case based data from the national surveillance system on acute and chronic hepatitis B. The Norwegian Statistics Bureau provided population and migration data and the Norwegian Institute for Alcohol and Drug Research the estimated number of active IDUs between 2002-2007. Incidence rates (IR and incidence rate ratios (IRR for acute hepatitis B and notification rates (NR and notification rate ratios (NRR for chronic hepatitis B with 95% confidence intervals were calculated. Results The annual IR of acute hepatitis B ranged from 0.7/100,000 (1992 to 10.6/100,000 (1999. Transmission occurred mainly among IDUs (64% or through sexual contact (24%. The risk of acquiring acute hepatitis B was highest in people aged 20-29 (IRR = 6.6 [3.3-13.3], and in males (IRR = 2.4 [1.7-3.3]. We observed two peaks of newly reported chronic hepatitis B cases in 2003 and 2009 (NR = 17.6/100,000 and 17.4/100,000, respectively. Chronic hepatitis B was more likely to be diagnosed among immigrants than among Norwegians (NRR = 93 [71.9-120.6], and among those 20-29 compared to those 50-59 (NRR = 5.2 [3.5-7.9]. Conclusions IDUs remain the largest risk group for acute hepatitis B. The observed peaks of chronic hepatitis B are related to increased immigration from high endemic countries and screening and vaccination of these groups is important to prevent further spread of infection. Universal screening of pregnant women should be introduced. A universal vaccination strategy should be considered, given the high cost of

    A previously healthy 16-year-old girl presented with signs of acute hepatitis. On initial enquiry, she had not taken any prescribed or 'over-the-counter' medications, and there was no recent travel history. Further investigations revealed no viral, autoimmune or metabolic cause of hepatitis. Only following specific questioning did she reveal that she had, in the preceding 3 months, regularly consumed internet ordered Chinese green tea, which contained Camellia sinensis. After ceasing green tea consumption, there was a rapid and sustained recovery of her hepatitis. The authors discuss the probable cause of herbal tea in this case of acute hepatitis, and the importance of awareness of this rare yet recurring theme for patients and clinicians alike.

    Adenosin deaminase (ADA) deficiency is the cause for Severe Combined Immunodeficiency (SCID) in about 15% of patients with SCID, often presenting as T (-)B (-)NK (-)SCID. Treatment options for ADA-SCID are enzyme replacement, bone marrow transplantation or gene therapy. We here describe the first patient with ADA-SCID and fatal hepatic failure despite bone marrow transplantation from a 10/10 HLA identical related donor. As patients with ADA-SCID may be at yet underestimated increased risk for rapid hepatic failure we speculate whether hepatitis in ADA-SCID should lead to the immediate treatment with enzyme replacement by pegylated ADA.

    In the present study, we assessed the efficiency of four BMSC transplantation methods as a therapy for liver failure. A rat model (80 Sprague-Dawley rats) of D-galactosamine (D-gal)/lipopolysaccharide (LPS)-induced acute liver failure (ALF) was established and the rats were divided into 5 groups: a hepatic artery injection group, a portal vein injection group, a vena caudalis injection group, an intraperitoneal injection group and a control group (16 per group). Following transplantation, the liver tissue and blood samples were collected on days 1, 3 and 7, we detected the EdU (5-ethynyl-2'-deoxyuridine)-labeled cells homing to the liver tissue and assessed the proliferating cell nuclear antigen (PCNA) and cysteine-containing aspartate-specific protease (caspase)-3 expression in the liver tissue and detected the levels of stromal cell-derived factor 1 (SDF-1) and hepatocyte growth factor (HGF) in the liver tissues. Compared with the control group, the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and damage to the liver tissue in the hepatic artery group, the portal vein group and the vena caudalis group improved in vivo. The expression of PCNA and HGF in the liver was higher and caspase-3 expression was lower in the hepatic artery injection group, the portal vein injection group and the vena caudalis injection group than that in the intraperitoneal injection and control groups. The EdU-labeled BMSCs were only observed homing to the liver tissue in these three groups. However, no significant differences were observed between these three groups. Liver function in the rats with ALF was improved following BMSC transplantation via 3 endovascular implantation methods (through the hepatic artery, portal vein and vena caudalis). These 3 methods were effective in transplanting BMSCs for the treatment of ALF. However, the selection of blood vessel in the implantation pathway does not affect the transplantation outcome.

    After a holiday in Egypt, a 57-year-old caucasian woman developed acute hepatitis A. The illness seemed initially to have a benign course, with a decreasing trend of hepatic enzymes and an apparent recovery. Three weeks later a relapse occurred. Recurrence of symptoms and aminotransferase elevation were associated with severe anemia; a hyporegenerative anemia was diagnosed and all laboratory findings were consistent with pure red cell aplasia. The haematologic disorder was successfully treated with red cell transfusion and glucocorticoids.

    The article presents information obtained during the survey in 64 patients with acute hepatitis B. We show that acute hepatitis B in patients with concomitant chronic toxic liver characterized by a marked imbalance of cytokine status due to a lower level of interleukin-2 and a higher content of interleukin-8, the highest levels of nitrite content, spontaneous oxidative modifications of blood proteins and the lowest content of L -arginine in the blood serum in the dynamics of disease compared with patients without this concomitant factor. In the period of convalescence these changes in patients with acute hepatitis B with concomitant chronic toxic liver characterized combined with higher cytolysis of liver cells, often circulating in the blood of HBsAg seroconversion and less frequently with the advent of anti-HBeAg.

    The clinical course of a 26 year old female patient with acute liver necrosis and coma due to hepatitis B is reported. The disturbances of conciousness had improved. The patient survived 41 days after the beginning of the coma and developed liver cell regeneration and an acute post-hepatitic liver cirrhosis. As a grave complication a septicemia with aspergillus was observed. The patient died because of gastro-intestinal hemorrhage. At autopsy there were no signs of brain edema. The treatment consisted in: daily infusions with coenzyme A, nicotinamid-adenin-dinucleotide, alpha lipoic acid and cocarboxylase to improve the metabolic disorders and the clinical picture; mannitol intravenously to prevent and to treat cerebral edema; 33 charcoal-hemoperfusions to remove toxic substances of acute liver failure. Treatment of the aspergillus infection with 5-fluorocytosine and amphotericine B and infusion of concentrated ascites led to a decompensation of liver functions. From this observation the following conclusions can be drawn: after an acute viral hepatic necrosis, new synthetic functions and improvements of the disturbed intermediary metabolism in regenerated liver-cells can eventually be seen only after twenty-four to thirty days. With systematically applicated mannitol infusions it is possible to treat cerebral edema effectively.

    The objective of this study was to determine the risk factors of postoperative acute renal failure (ARF) in orthotopic liver transplantation (OLT). We reviewed 184 consecutive OLT. Postoperative ARF was defined as a persistent rise of 50% increase or more of the S-creatinine (S-Cr). The patients were classified as early postoperative ARF (E-ARF) (first week) and late postoperative ARF (L-ARF) (second to fourth week). Preoperative variables were age, sex, comorbidity, indication for OLT, Child-Pugh stage, united network for organ sharing status, analysis of the blood and urine, and donor's data. Intraoperative variables were systolic arterial pressure, mean arterial pressure, pulmonary capillary wedge pressure, cardiac index, and systemic vascular resistance index. Surgical technique, number of blood products transfused, need for adrenergic agonist drugs, and intraoperative complications were also important. Postoperative variables were duration of stay in the intensive care unit, time on mechanic ventilation, liver graft dysfunction, need for adrenergic agonist drugs, units of blood products infused, episodes of acute rejection, re-operations, and bacterial infections. Firstly we carried out a univariate statistical analysis, and secondly a logistic regression analysis. The risk factors for E-ARF were: pretransplant ARF (odds ratio (OR)=10.2, P=0.025), S-albumin (OR=0.3, P=0.001), duration of treatment with dopamine (OR=1.6, P=0.001), and grade II-IV dysfunction of the liver graft (OR=5.6, P=0.002). The risk factors for L-ARF were: re-operation (OR=3.1, P=0.013) and bacterial infection (OR=2.9, P=0.017). The development of E-ARF is influenced by preoperative factors such as ARF and hypoalbuminemia, as well as postoperative factors such as liver dysfunction and prolonged treatment with dopamine. The predicting factors of L-ARF differ from E-ARF and correspond to postoperative causes such as bacterial infection and surgical re-operation.

    Acute liver failure (ALF)-related encephalopathy was previously characterized by MR spectroscopy of single voxels containing both grey and white matter brain tissue. Quantitative multivoxel MRS was used here to compare grey and white matter brain tissue concentrations of glutamate/glutamine (Glx) and lactate in ALF and associate the results with other liver function parameters. Five pediatric patients with ALF-related encephalopathy and five controls, examined after successful liver transplantation, were examined by brain MRI/MRS. ALF patients had higher Glx and lactate concentrations in brain white matter than controls (Glx + 125%: P < 0.01; lactate + 33%, P < 0.05) and higher Glx in grey matter (Glx + 125%: P < 0.01). Within the group of ALF patients positive correlations were found between grey or white matter lactate concentration and serum ammonia (P < 0.05), and negative correlations between grey or white matter Glx and venous pH (P < 0.001). This is the first study presenting evidence of high Glx levels in both white and grey matter brain tissue in ALF-related encephalopathy. The elevations in CNS Glx and lactate concentrations appear to relate to hepatic detoxification (ammonia, venous pH), rather than to liver parenchymal integrity (aspartate aminotransferase, alanine aminotransferase) or biliary cholestasis (bilirubin, {gamma}-glutamyl transpeptidase, alkaline phosphatase).

    Background Mostly because of the limited number and proliferative ability of the transplanted hepatocytes,hepatocyte transplantation offers only temporary support to the hepatic function with rather poor functional replacement of the damaged liver parenchyma.This study aimed to observe the therapeutic effect of human thioredoxin(hTrx)gene-modified hepatocytes on experimental acute liver failure in rats.Methods hTrx cDNA was obtained by reverse transcription-polymerase chain reaction(RT-PCR)from human osteosercoma 143(TK-)cells to construct the recombinant retrovirus vector pLEGFP/hTrx,which was packaged into PA317 cells to collect the recombinant retrovirus containing hTrx gene.After titration and characterization,the recombinant retrovirus was applied to primary cultured rat hepatocyte for infection to generate hTrx gene-modified rat hepatocytes,whose viability and antioxidative capacity were examined by immunohistochemistry and MIF assay,respectively.In a Sprague-Dawley(SD)rat model of acute liver failure,the modified hepatocytes were injected into the spleen,and the hepatic function and survival rate of the recipient rats were evaluated at different time points after the transplantation.Results NIH3T3 cells infected by the recombinant retrovirus were capable of expressing bioactive hTrx in the form of fusion proteins.Immunohistochemistry demonstrated normal function of the hTrx gene-modified hepatocytes,which possessed strong antioxidative capacity as shown by MTT assay.Transplantation of the modified hepatocytes in rats with acute liver failure resulted in significantly lowered serum alanine aminotransferase(ALT)and total bilirubin(TBIL)levels(P<0.05).The hepatocytes exhibited long-term survival and efficient proliferation after transplantation.Fourteen days after the operation,the rat models receiving hTrx gene-modified hepatocytes had significantly higher survival rate than those without the transplantation.Conclusion hTrx gene-modifled hepatocyte

    Hepatitis E virus (HEV) infections are responsible for chronic hepatitis in immunocompromised patients, and this can evolve to cirrhosis. Like all RNA viruses, HEV exists as a mixture of heterogeneous viruses defining quasispecies. The relationship between the genetic heterogeneity described as a quasispecies, cytokine secretion, and the outcome of acute hepatitis in immunocompromised patients remains to be elucidated. We cloned and sequenced the region encoding the M and P capsid domains of HEV from eight solid-organ transplant (SOT) patients with acute HEV infection who subsequently cleared the virus and from eight SOT patients whose infection became chronic. We analyzed the cytokines and chemokines in the sera of these SOT patients by multianalyte profiling. The nucleotide sequence entropy and genetic distances were greater in patients whose infections became chronic. A lower K(a)/K(s) ratio was associated with the persistence of HEV. The patients who developed chronic infection had lower serum concentrations of interleukin-1 (IL-1) receptor antagonist and soluble IL-2 receptor. Increased concentrations of the chemokines implicated in leukocyte recruitment to the liver were associated with persistent infection. Those patients with chronic HEV infection and progressing liver fibrosis had less quasispecies diversification during the first year than patients without liver fibrosis progression. Great quasispecies heterogeneity, a weak inflammatory response, and high serum concentrations of the chemokines involved in leukocyte recruitment to the liver in the acute phase were associated with persistent HEV infection. Slow quasispecies diversification during the first year was associated with rapidly developing liver fibrosis.

    To predict the potential utility of calcitriol in human osteoporosis with hepatic dysfunction, we examined the effects of calcitriol and alfacalcidol in ovariectomized (OVX) aged-rats with CCl4-induced hepatic failure. In OVX+CCl4 rats, GOT, GTP, alkaline phosphatase and total bilirubin increased and hepatic enzyme activity (cytochrome b5 and P450) decreased. Repeated oral doses of calcitriol (0.1 and 0.2 microgram/kg) for 51 days inhibited a decrease in serum calcium concentration. This effect was more potent than that of alfacalcidol at the same dose. Both drugs tended to inhibit a decrease in femoral calcium contents. Calcitriol (0.2 microgram/kg) prevented a decrease in femoral bone density (dry and ash weight per volume), unlike alfacalcidol. Soft X-ray imaging analysis revealed that both drugs tended to inhibit the decrease in femoral bone density. There were no differences in the femoral bone strength between OVX+CCl4 and sham-operated rats. The serum calcitriol concentrations increased after the last doses of calcitriol, while they did not increase after the last dose of alfacalcidol. All these effects of calcitriol were related to the serum calcitriol levels. These results suggest that calcitriol, unlike alfacalcidol, may have a clinical therapeutic effect in osteoporosis with hepatic dysfunction.

    We present a case of fetal liver failure caused by the activation of lamivudine-resistant hepatitis B virus (HBV) nine months after lamivudine treatment. A 57-year old man visited our hospital for the treatment of decompensated chronic hepatitis B. Lamivudine was started in December 2001. Subsequently, serum HBV was negative for HBV DNA with seroconversion from HBeAg to anti-HBe and improvement of liver function. However, HBV DNA and HBeAg were again detected in September 2002. He was complicated by breakthrough hepatitis and admitted to our hospital in November for severely impaired liver function. Vidarabine treatment was started and serum HBV DNA and alanine aminotransferase (ALT) decreased transiently. However, after the start of a-interferon treatment, HBV DNA level increased and liver function deteriorated. He died 1 mo after admission. An analysis of amino acid sequences in the polymerase region revealed that rtM204I/V with rtL80I/V occurred at the time of viral breakthrough. After the start of antiviral treatment, rtL180M was detected in addition to rtM204I/V and rtL80I/V, and became predominant in the terminal stage of the disease. HBV clone with a high replication capacity may be produced by antiviral treatment leading to the worsening of liver function. Antiviral therapy for patients with breakthrough hepatitis in advanced liver disease should be carefully performed.

    From 1978 to 1993 a study of acute viral hepatitis contracted by the Japan Overseas Cooperation Volunteers (JOCV) during their assignments in tropical and subtropical countries was conducted. Of 10,509 subjects in this study, 240 cases of acute viral hepatitis were confirmed (hepatitis A = 139, hepatitis B = 72, and non-A, non-B hepatitis = 29). The annual morbidity was 5.1% in 1978 and 4.9% in 1979, with hepatitis A accounting for 80% of the cases. However, it decreased significantly after the prophylactic inoculation with immune serum globulin (ISG) was started in 1980. A significant decrease of hepatitis B from 1.2% in 1980 to 0.1% in 1990 was also seen after vaccination was introduced for all volunteers in 1988. Health education concerning food and water sanitation, and providing general information on viral hepatitis, was also conducted throughout this period. These results indicate that acute viral hepatitis could be successfully prevented in the JOCV with a combination of ISG, hepatitis B vaccination, and health education.

    Full Text Available OBJECTIVE: Colistin is a polymyxin antibiotic with a polypeptide structure and is effective against gram-negative bacilli. Although its use had decreased due to its side effects, it has increased again in recent years, especially for multi-drug resistant Pseudomonas aeruginosa, Klebsiella pneumoniae, Acinetobacter and Enterobacteriaceae. In the present study, patients that received colistin at one center were retrospectively analysed in terms of nephrotoxicity. MATERIAL and METHODS: Patients hospitalized and treated with colistin in the intensive care unit between January 2012 and August 2013 were analyzed. Demographic data; biochemical tests at baseline, daily during hospitalization and after discharge; and the initial, maintenance and total doses of colistin were evaluated. RESULTS: The mean age was 62±13 (31-86 years for the 27 patients with 17 (63% males that were followed-up for an average duration of 63±89 days. During follow-up, 18 patients (66.7% developed acute renal failure (ARF and 17 (63% of died. There were 12 (66.7% mortalities in the ARF group and 5 (55% in the group without ARF ( p> 0.05. The total colistin dose and leukocyte count were higher in the ARF group with 3.75±2.34 g and 12.04±5.05/mm3 than the non-ARF group at 3.32±1.86 g and 7.60±3.7/mm3 but did not reach statistical significance. CONCLUSION: ARF increases the mortality in ICU patients. Although colistin is an effective therapeutic agent used for resistant infections, we have to avoid higher doses due to its potential side effect of ARF.

    The most serious forms of acute renal failure (ARF) are nowadays encountered in the intensive care unit (ICU), where up to 25% of new patients are reported to develop ARF. Lethality rates may reach 50 to 90% when the ARF is part of a multiple organ dysfunction syndrome. A multitude of extracorporeal procedures have been introduced into intensive care medicine. Applied with adequate skills and experience, most of these techniques will suffice to replace excretory renal function. However, because of low efficacy arterio-venous procedures (CAVH and CAVHD) have been abandoned for the veno-venous, pump-driven techniques (CVVH and CVVHD). Up to now, there is no consensus whether continuous or intermittent renal replacement therapy is more advantageous. In many cases, oliguric patients with circulatory instability will be treated by CVVH, even though there is no prospective study to show that in terms of outcome continuous treatment is superior to intermittent hemodialysis. It is equally conceivable to treat such patients with daily, prolonged (intermittent) hemodialysis. Apparently, the dose of replacement therapy, be it continuous filtration (36 to 48 l/24 h) or intermittent hemodialysis (daily 3 to 4 h) with a target BUN of less than 50 mg/dl, is more important than the modality of treatment. Moreover, there is good evidence that the use of biocompatible membranes (no complement- or leukocyte activation) is preferable and that with high-volume hemofiltration bicarbonate-containing replacement fluids should be used. However, despite all the technical advances, we firmly believe that the skills and the experience of those physicians and nurses who actually perform renal replacement therapy in the ICU are more important than the modality of treatment applied.

    Many aspects of the management of renal replacement therapy in acute renal failure (ARF), including the appropriate assessment of dialysis adequacy, remain unresolved, because ARF patients often are not in a metabolic steady state. The aim of this study was to evaluate a system of adequacy indices for dialysis in ARF patients using urea and creatinine kinetic modeling. Kinetic modeling was performed for two different fictitious patients (A and B) with characteristics described by the average parameters for two patient groups and for two blood purification treatments: sustained low efficiency daily dialysis (SLEDD) in Patient A and continuous venovenous hemofiltration (CVVH) in Patient B, based on data from a clinical report. Urea and creatinine generation rates were estimated according to the clinical data on the solute concentrations in blood. Then, using estimated generation rates, two hypothetical treatments were simulated, CVVH in Patient A and SLEDD in Patient B. KT/V, fractional solute removal (FSR) and equivalent renal clearance (EKR) were calculated according to the definitions developed for metabolically unstable patients. CVVH appeared as being more effective than SLEDD because KT/V, FSR, and EKR were higher for CVVH than SLEDD in Patients A and B. Creatinine KT/V, FSR, and EKR were lower and well correlated to the respective indices for urea. Urea and creatinine generation rates were overestimated more than twice in Patient A and by 30-40% in Patient B if calculated assuming the metabolically stable state than if estimated by kinetic modeling. Adequacy indices and solute generation rates for ARF patients should be estimated using the definition for unsteady metabolic state. EKR and FSR were higher for urea and creatinine with CVVH than with SLEDD, because of higher K.T and minimized compartmental effects for CVVH.

    Dubin-Johnson syndrome is a rare clinical entity. It shows intermittent symptoms such as chronic or intermittent jaundice, abdominal pain, weakness, nausea, vomiting, anorexia and diarrhea. Symptoms are precipitated or aggravated by pregnancy, alcoholism, surgical procedures and intercurrent disease. Chronic idiopathic jaundice is typical of Dubin-Johnson syndrome and its prognosis is good. We describe a case of prolonged cholestasis for more than 10 months caused by acute A viral hepatitis in a patient with Dubin-Johnson syndrome. It is a first report of cholestasis complicated by acute A viral hepatitis in a patient with Dubin-Johnson syndrome.

    AIMS: We examined risk of developing acute renal failure and the associated mortality among patients aged > 65 years undergoing surgery for a fracture of the hip. PATIENTS AND METHODS: We used medical databases to identify patients who underwent surgical treatment for a fracture of the hip...... in Northern Denmark between 2005 and 2011. Acute renal failure was classified as stage 1, 2 and 3 according to the Kidney Disease Improving Global Outcome criteria. We computed the risk of developing acute renal failure within five days after surgery with death as a competing risk, and the short-term (six...... to 30 days post-operatively) and long-term mortality (31 days to 365 days post-operatively). We calculated adjusted hazard ratios (HRs) for death with 95% confidence intervals (CIs).

    2015-02-01

    Over a million patients get hospitalized with the diagnosis of acute decompensated heart failure which poses an insurmountable financial burden on the health care system. Heart failure alone incurs over 30 billion dollars with half the cost spent towards acute hospitalizations. Majority of the treatment strategies have focused towards decongesting patients which often comes with the cost of worsening renal function. Renal dysfunction in the setting of acute decompensated heart failure portends worse morbidity and mortality. Recently, there has been a change in the focus with shift towards therapies attempting to conserve renal function. In the past decade, we have witnessed several large randomized controlled trials testing the established as well as emerging therapies in this subset of population with mixed results. This review intends to provide a comprehensive overview of the pharmacologic therapies commonly utilized in the management of acute decompensated heart failure and the body of evidence supporting these strategies.

  10. The management of neonatal acute and chronic renal failure: A review.

    Most babies with chronic renal failure are identified antenatally, and over half that are treated with peritoneal dialysis receive kidney transplants before school age. Most infants that develop acute renal failure have hypotension following cardiac surgery, or multiple organ failure. Sometimes the falls in glomerular filtration and urine output are physiological and reversible, and sometimes due to kidney injury, but (illogically) it is now common to define them all as having 'acute kidney injury'. Contrary to widespread opinion, careful interpretation of the plasma creatinine concentrations can provide sensitive evidence of early acute renal failure. Conservative management frequently leads to under-nutrition or fluid overload. Acute peritoneal dialysis is often technically fraught in very small patients, and haemotherapies have been limited by vascular access and anticoagulation requirements, the need to blood-prime circuits, and serious limitations in regulating fluid removal. Newer devices, including the Nidus, have been specifically designed to reduce these difficulties.

    Nitrates are potent venous dilators and anti-ischemic agents. They are widely used for the relief of chest pain and pulmonary congestion in patients with acute coronary syndromes and heart failure. Nitrates, however, do not reduce mortality in patients with acute coronary syndromes. Combination of nitrates and hydralazine when given in addition to beta-blockers and angiotensin-converting enzyme (ACE) inhibitors reduce mortality and heart failure hospitalizations in patients with heart failure due to left ventricular systolic dysfunction who are of African-American origin. Side effects during nitrate therapy are common but are less well described in the literature compared with the reported side effects in patients with stable angina pectoris. The reported incidence of side effects varies highly among different studies and among various disease states. Headache is the most commonly reported side effect with an incidence of 12% in acute heart failure, 41-73% in chronic heart failure, 3-19% in unstable angina and 2-26% in acute myocardial infarction. The reported incidence of hypotension also differs: 5-10% in acute heart failure, 20% in chronic heart failure, 9% in unstable angina and < 1-48% in acute myocardial infarction, with the incidence being much higher with concomitant nitrate therapy plus angiotensin-converting enzyme inhibitors. Reported incidence of dizziness is as low as 1% in patients with acute myocardial infarction to as high as 29% in patients with heart failure. Severe headaches and/or symptomatic hypotension may necessitate discontinuation of nitrate therapy. Severe life threatening hypotension or even death may occur when nitrates are used in patients with acute inferior myocardial infarction associated with right ventricular dysfunction or infarction, or with concomitant use of phosphodiesterase-5 inhibitors or N-acetylcysteine. Despite the disturbing observational reports in the literature that continuous and prolonged use of nitrates may lead to

    Wilson's disease associated with hepatic failure is not common and the underlying mechanism triggering the event is not known at present. We treated a 28-year-old Japanese woman with Wilson's disease who developed hepatic failure associated with hemolytic crisis just after delivery. She was diagnosed as having Wilson's disease at 12 years of age, at which time she started taking D-penicillamine. She had previously delivered two children without difficulty. When she found out she was pregnant this time, she stopped taking D-penicillamine in contrast to taking it faithfully during her first two pregnancies. On the day of delivery of her full-term baby, jaundice developed accompanied with severe hemolytic crisis. Plasma exchanges and blood transfusion were performed and D-penicillamine administration was started again. She gradually recovered and apparently was following a good clinical course. However, on day 30 the second hemolytic crisis occurred and subsequent liver failure led her to death on day 50. At autopsy her liver was cirrhotic and showed massive necrosis. Prophylactic oral administration of D-penicillamine and careful observation are therefore recommended to prevent hemolytic crisis during the perinatal period.

    Full Text Available Aim. The case of successful surgical treatment of anterolateral papillary muscle rupture due to acute myocardial infarction with cardiogenic shock, pulmonary edema and acute renal failure. Case report. A 62-year old male from Belgrade with chest pain, hypotension and a new heart murmur refused hospitalization at the Military Medical Academy. On the third day of his illness he was readmitted to MMA as an emergency due to hemoptysis. Examination revealed mitral valve anterolateral papillary muscle rupture. The patient, with signs of cardiogenic shock and acute renal failure, was immediately operated on. The surgery was performed using extracorporeal circulation. An artificial mitral valve was implanted, and myocardial revascularization accomplished with one venous graft of the left anterior descending artery. On the second postoperative day, hemodialysis was carried out due to acute renal failure. On the 28th postoperative day, the patient was discharged from the hospital being hemodynamically stable with normal renal function and balanced anticoagulation. The case is interesting in terms of unrecognized papillary muscle rupture that led to the development of cardiogenic shock, hemoptysis and acute renal failure. Conclusion. Papillary muscle rupture is a fatal complication of acute myocardial infarction. Early recognition and urgent surgical intervention were lifesaving in the case of complete papillary muscle rupture. Surgical treatment, regardless of high risk, is the procedure of choice.

    Fulminant hepatic failure (FHF) is a critical illness that can be comorbid to primary liver damage. FHF shows a high mortality rate, and patients with FHF require intensive therapy, including plasma apheresis. However, intensive care at the present is not enough to restore the severe liver damage or promote hepatocellular reproduction, and a standard therapy for the treatment of FHF has not been established. An 86-year-old female with FHF was admitted to our hospital. Her manifestation demonstrated a clinical situation of systemic inflammatory response syndrome (SIRS) and disseminated intravascular coagulation. A diagnosis of fulminant hepatitis was made according to the definition given in the position paper of the American Association for the Study of Liver Diseases. Her serum hepatocyte growth factor (HGF) level had increased to 11.84 ng/mL. The HGF level indicated massive liver damage as seen in FHF. Recombinant thrombomodulin (rTM) was administered daily from the admission day for 1 wk at 380 U/kg. The patient's white blood cells and C-reactive protein responded to the rTM treatment within a few days. The HGF level and PT recovered to the normal range. The levels of proinflammatory cytokines (tumor necrosis factor-α and interleukin-1β) were suppressed by the administration of rTM. The patient's hepatic function (e.g., PT and albumin) completely recovered without plasma exchange. rTM may modulate the over-response of SIRS with the improvement of proinflammatory cytokines. The underlying mechanism is thought to be the inhibitory effect of rTM on high-mobility group box 1 (HMBG1). The pathogenesis of HMBG1 protein in fulminant hepatic failure has been already known. A novel favorable effect of rTM for SIRS would be promising for FHF, and the wide application of rTM for SIRS should be considered.

    Full Text Available Background & objectives: Jaundice is one of the common manifestations of severe malaria in adults.The purpose of this study is to compare the pattern of clinical and biochemical parameters such asserum bilirubin and liver enzyme levels in patients of malaria with jaundice and acute viral hepatitis.Methodology: The present study was conducted on 34 patients of malaria with jaundice and 15patients of acute viral hepatitis. Estimation of serum bilirubin, aspartate amino transferase (AST,alanine amino transferase (ALT and alkaline phosphatase was done daily using standard proceduresin malaria patients and weekly in acute viral hepatitis patients.Results: Mean level of serum bilirubin on first day in malaria and acute viral hepatitis patients was7.07 ± 3.94 and 10.38 ± 7.87 mg%, whereas on Day 8 it was 1.19 ± 1.43 and 7.88 ± 7.02 mg%respectively. Mean level of AST on Day 1 in malaria and acute viral hepatitis patients was 158.47 ±120.35 and 1418.6 ± 834.11 IU/L, whereas on Day 8 it was 41 ± 28.33 and 775.3 ± 399.01IU/L respectively. Mean level of ALT on Day 1 in malaria and acute viral hepatitis patients was220.14 ± 145.61 and 1666.67 ± 1112.77 IU/L, whereas on Day 8 it was 50.85 ± 37.31 and 823.8 ±475.06 IU/L respectively. Mean level of serum alkaline phosphatase on Day 1 in malaria and acuteviral hepatitis patients was 394.74 ± 267.78 and 513.4 ± 324.7 IU/L, whereas on Day 8 it was84.76 ± 68.50 and 369.27 ± 207.75 IU/L respectively.Interpretation & conclusion: We observed that resolution of jaundice in malaria took 1–2 weeks incontrast 6 to 8 weeks in viral hepatitis. This difference in duration was statistically significant. Thus,jaundice not resolving in 1–2 weeks time in a patient of malaria requires serious consideration forpresence of other concomitant diseases including viral hepatitis.

    2014-01-01

    Full Text Available Background. Acetaminophen (APAP is a commonly used analgesic and antipyretic. When administered in high doses, APAP is a clinical problem in the US and Europe, often resulting in severe liver injury and potentially acute liver failure. Studies have demonstrated that antioxidants and anti-inflammatory agents effectively protect against the acute hepatotoxicity induced by APAP overdose. Methods. The present study attempted to investigate the protective effect of B. trimera against APAP-induced hepatic damage in rats. The liver-function markers ALT and AST, biomarkers of oxidative stress, antioxidant parameters, and histopathological changes were examined. Results. The pretreatment with B. trimera attenuated serum activities of ALT and AST that were enhanced by administration of APAP. Furthermore, pretreatment with the extract decreases the activity of the enzyme SOD and increases the activity of catalase and the concentration of total glutathione. Histopathological analysis confirmed the alleviation of liver damage and reduced lesions caused by APAP. Conclusions. The hepatoprotective action of B. trimera extract may rely on its effect on reducing the oxidative stress caused by APAP-induced hepatic damage in a rat model. General Significance. These results make the extract of B. trimera a potential candidate drug capable of protecting the liver against damage caused by APAP overdose.

    Linarin was isolated from Chrysanthemum indicum L. Fulminant hepatic failure is a serious clinical syndrome that results in massive inflammation and hepatocyte death. Apoptosis is an important cellular pathological process in d-galactosamine (GalN)/lipopolysaccharide (LPS)-induced liver injury, and regulation of liver apoptosis might be an effective therapeutic method for fulminant hepatic failure. This study examined the cytoprotective mechanisms of linarin against GalN/LPS-induced hepatic failure. Mice were given an oral administration of linarin (12.5, 25 and 50mg/kg) 1h before receiving GalN (800 mg/kg)/LPS (40 μg/kg). Linarin treatment reversed the lethality induced by GalN/LPS. After 6h of GalN/LPS injection, the serum levels of alanine aminotransferase, aspartate aminotransferase, tumor necrosis factor (TNF)-α, interleukin-6 and interferon-γ were significantly elevated. GalN/LPS increased toll-like receptor 4 and interleukin-1 receptor-associated kinase protein expression. These increases were attenuated by linarin. Linarin attenuated the increased expression of Fas-associated death domain and caspase-8 induced by GalN/LPS, reduced the cytosolic release of cytochrome c and caspase-3 cleavage induced by GalN/LPS, and reduced the pro-apoptotic Bim phosphorylation induced by GalN/LPS. However, linarin increased the level of anti-apoptotic Bcl-xL and phosphorylation of STAT3. Our results suggest that linarin alleviates GalN/LPS-induced liver injury by suppressing TNF-α-mediated apoptotic pathways.

    The aim of this study was to document the changes in Doppler ultrasound variables of the hepatic artery and portal vein in fulminant and severe acute liver failure, and to assess their prognostic significance. 18 adult patients with fulminant and severe acute liver failure underwent serial Doppler sonography, in the early stages after presentation. 12 hourly measurements of hepatic artery resistance index (HARI), spleen length, portal vein cross-sectional area, time average velocity (TAV) and flow volume were performed. Mean HARI (p = 0.03) and mean maximum HARI (p = 0.03) were significantly higher in those who fulfilled criteria for liver transplantation. Increased portal vein flow was demonstrated, although the difference between the groups was not significant. A significant increase in portal vein cross-sectional area (p spleen length (p liver has been demonstrated. The mean HARI is significantly higher in patients who fulfil transplant criteria and may possibly be used as an indicator of poorer prognosis and the need for liver transplantation in acute severe and fulminant liver failure.

    Full Text Available Fulminant hepatic failure (FHF is often accompanied by a myriad of neurologic complications, which are associated with high morbidity and mortality. Although appropriate neuromonitoring is recommended for early diagnosis and to minimize secondary brain injury, individuals with FHF usually have a high chance of coagulopathy, which limits the ability to use invasive neuromonitoring. Jugular bulb venous oxygen saturation (JvO2 monitoring is well known as a surrogate direct measures of global brain oxygen use. We report the case of a patient with increased intracranial pressure due to FHF, in which JvO2 was used for appropriate brain oxygen monitoring.

    The liver is one of the commonest sites of metastatic involvement in breast cancer, usually evident as focal lesions on imaging tests. Rarely, the pattern of metastatic spread is so diffuse that it remains radiologically occult. Such patients usually present with signs of hepatic insufficiency without any focal lesions on liver imaging. In such cases, liver biopsy is required to make a definitive diagnosis. We report a case of a 56-year-old postmenopausal woman with metastatic breast cancer who presented with subacute progressive liver failure. Repeated imaging of the liver was normal or non-descript. Liver biopsy finally established the diagnosis of intrasinusoidal metastases from breast cancer.

  12. Acute sterol o-acyltransferase 2 (SOAT2 knockdown rapidly mobilizes hepatic cholesterol for fecal excretion.

    Directory of Open Access Journals (Sweden)

    Stephanie M Marshall

    Full Text Available The primary risk factor for atherosclerotic cardiovascular disease is LDL cholesterol, which can be reduced by increasing cholesterol excretion from the body. Fecal cholesterol excretion can be driven by a hepatobiliary as well as a non-biliary pathway known as transintestinal cholesterol efflux (TICE. We previously showed that chronic knockdown of the hepatic cholesterol esterifying enzyme sterol O-acyltransferase 2 (SOAT2 increased fecal cholesterol loss via TICE. To elucidate the initial events that stimulate TICE, C57Bl/6 mice were fed a high cholesterol diet to induce hepatic cholesterol accumulation and were then treated for 1 or 2 weeks with an antisense oligonucleotide targeting SOAT2. Within 2 weeks of hepatic SOAT2 knockdown (SOAT2HKD, the concentration of cholesteryl ester in the liver was reduced by 70% without a reciprocal increase in hepatic free cholesterol. The rapid mobilization of hepatic cholesterol stores resulted in a ∼ 2-fold increase in fecal neutral sterol loss but no change in biliary cholesterol concentration. Acute SOAT2HKD increased plasma cholesterol carried primarily in lipoproteins enriched in apoB and apoE. Collectively, our data suggest that acutely reducing SOAT2 causes hepatic cholesterol to be swiftly mobilized and packaged onto nascent lipoproteins that feed cholesterol into the TICE pathway for fecal excretion.

    Full Text Available Non invasive positive pressure ventilation (NPPV is increasingly used for patients with hypercapnic respiratory failure secondary to acute exacerbation of chronic obstructive pulmonary disease (COPD. NPPV has been shown to improve arterial blood gas tensions and dyspnoea and to prevent the need for intubation in patients admitted to hospital with an exacerbation of COPD associated with respiratory acidosis. Although advantages of NPPV over conventional treatment have been convincingly documented in the short period, there are fewer data as to the outcomes following hospital discharge. We have undertaken a prospective descriptive study to obtain comprehensive data on the in hospital and 3 month outcomes of a cohort of 57 COPD patients treated with NPPV for acute hypercapnic respiratory failure as a first intervention in addition to usual medical care. Patients with a COPD exacerbation had better outcomes than patients with COPD complicated by other acute conditions. Pneumonia was specifically associated with a higher inhospital risk of death. In our series about one in four patients with an indicator of previous severe respiratory disease (past admission for acute respiratory failure, previous use of NPPV, long term oxygen therapy or home NPPV was dead at three months after discharge and almost one in two was dead or had been readmitted. On the contrary, patients without indicators of previous severe respiratory disease benefited from NPPV during an acute episode of respiratory failure and had a chance of approximately 80% of being alive and free from recurrence at three months.

    Full Text Available Abstract Background Many people now seek alternative methods of weight loss. The internet provides a readily available source of weight reduction products, the ingredients of which are often unclear. The authors describe a case of acute hepatitis in a 20 year old woman caused by such a product purchased over the internet. Case Presentation A 20-year old woman presented with a two day history of abdominal pain, vomiting and jaundice. There were no identifiable risk factors for chronic liver disease. Liver function tests demonstrated an acute hepatitis (aminoaspartate transaminase 1230 IU/L. A chronic liver disease screen was negative. The patient had started a weight loss product (Pro-Lean, purchased over the internet two weeks prior to presentation. The patient was treated conservatively, and improved. The sequence of events suggests an acute hepatitis caused by an herbal weight loss product. Conclusion This case report highlights the dangers of weight loss products available to the public over the internet, and the importance of asking specifically about alternative medicines in patients who present with an acute hepatitis.

    2011-05-01

    Full Text Available Abstract Pheochromocytomas are catecholamine producing tumors arising mostly from chromaffin cells of the adrenal medulla. The most common clinical presentation is hypertension, mainly in the form of paroxymal episodes. Cardiovascular manifestations include malignant arrhythmia and catecholamine cardiomyopathy, mimicking acute coronary syndromes and acute heart failure. There are reports of pheochromocytomas presenting as acute coronary syndrome and rapidly leading to cardiogenic shock; the failure of intensive medical treatment in these cases has prompted the need for emergency adrenalectomy as the only remaining option. We report on a case of complicated pheochromocytoma presenting as cardiogenic shock, in which emergency adrenalectomy was performed following a total lack of response to intensive medical treatment.

    Abstract Background: Pheochromocytoma is an endocrine tumor that causes hypertension, facial pallor, and headache. Pheochromocytoma patients rarely present with acute heart failure or cardiogenic shock. Method: We discuss the case of a female patient with Takotsubo-pattern cardiomyopathy who presented with acute heart failure caused by pheochromocytoma. Result: Treatment was adjusted based on the data of the pulse contour cardiac output system. After intensive hydration and medication for heart failure, the condition of the patient stabilized. Conclusion: Before confirming the diagnosis, pulse contour cardiac output data could provide a direction for diagnosis and treatment. PMID:27603405

    Acute heart failure (AHF) is a clinical syndrome of different etiology and several clinical presentations. Cardiogenic shock patients have highest long-term mortality. In contrast to chronic heart failure, we have no evidence of therapeutic benefit for any treatment strategy from randomized clinical trials. Search for new pharmacologic and non-pharmacologic therapies is ongoing. Both causal and symptomatic treatment of AHF episode should be initiated as soon as possible. This review is focused on trends in acute heart failure therapy at the beginning of 21st century.
