    The article deals with a study of 243 patients (from 18 to 65 years old) with acute hepatic failure. Purpose of the study was to evaluate the predictive capability of severity scales APACHE III, SOFA, MODS, Child-Pugh and to identify mortality predictors in patients with acute hepatic failure. Results; The best predictive ability in patients with acute hepatic failure and multiple organ failure had APACHE III and SOFA scales. The strongest mortality predictors were: serum creatinine > 132 mmol/L, fibrinogen < 1.4 g/L, Na < 129 mmol/L.

    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 fre...

    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.

    Full Text Available There are occasional pediatric reports of parvovirus B19-associated transient acute hepatitis and hepatic failure. A case of a 34-year-old immunocompetent woman who developed severe and prolonged but self-limited acute hepatitis and myelosuppression following acute parvovirus B19 infection is reported. Parvovirus B19 may be the causative agent in some adult cases of acute non-A-E viral hepatitis and acute liver failure.

    Neonatal hepatitis with acute liver failure due to varied etiology including various infections is reported in the past. Scrub typhus as a cause of neonatal hepatitis has rarely been reported in literature. A high index of clinical suspicion is required for early diagnosis and timely treatment. Severity and prognosis of the disease varies widely because several different strains of Orientia tsutsugamushi exist with different virulence. Delayed diagnosis can result in complication and significant morbidity and mortality. Here, we report three cases of neonatal hepatitis with acute liver failure caused by scrub typhus to increase awareness.

    Glutathione-S-transferase P1 (GSTP1) methylation has been demonstrated to be associated with oxidative stress induced liver damage in acute-on-chronic hepatitis B liver failure (ACHBLF). To evaluate the methylation level of GSTP1 promoter in acute-on-chronic hepatitis B liver failure and determine its predictive value for prognosis. One hundred and five patients with acute-on-chronic hepatitis B liver failure, 86 with chronic hepatitis B (CHB) and 30 healthy controls (HC) were retrospectively enrolled. GSTP1 methylation level in peripheral mononuclear cells (PBMC) was detected by MethyLight. Clinical and laboratory parameters were obtained. GSTP1 methylation levels were significantly higher in patients with acute-on-chronic hepatitis B liver failure (median 16.84%, interquartile range 1.83-59.05%) than those with CHB (median 1.25%, interquartile range 0.48-2.47%; P chronic hepatitis B liver failure group, nonsurvivors showed significantly higher GSTP1 methylation levels (P chronic hepatitis B liver failure, GSTP1 methylation showed significantly better predictive value than MELD score [area under the receiver operating characteristic curve (AUC) 0.89 vs. 0.72, P chronic hepatitis B liver failure and shows high predictive value for short-term mortality.

  7. Hepatic encephalopathy in acute-on-chronic liver failure.

    2015-10-01

    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.

    Full Text Available 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.

    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.

    Full Text Available ObjectiveTo investigate the prognostic factors for patients with hepatitis B virus-related acute-on-chronic liver failure, and to provide a basis for clinical diagnosis and treatment. MethodsA total of 172 patients with hepatitis B virus (HBV-related acute-on-chronic liver failure who were admitted to The First Hospital of Jilin University from January 1, 2006 to January 1, 2016 and had complete medical records and follow-up data were enrolled, and a retrospective analysis was performed for their clinical data and laboratory markers to determine prognostic factors. The independent-samples t test was used for comparison of continuous data between groups, the chi-square test was used for comparison of categorical data between groups, and a multivariate logistic regression analysis was performed for the indices determined to be statistically significant by the univariate analysis to screen out independent risk factors for the prognosis of patients with HBV-related acute-on-chronic liver failure. ResultsThe multivariate logistic regression analysis was performed for the indices determined to be statistically significant by the univariate analysis, and the results showed that the prognostic factors were total bilirubin (TBil, prothrombin time activity (PTA, Na+, total cholesterol (TC, Child-Turcotte-Pugh (CTP score, age ≥50 years, the presence of liver cirrhosis, bilirubin-enzyme separation, and complications. The multivariate regression analysis was performed for the complications determined to affect prognosis by the univariate analysis, and the results showed that the complications as risk factors were hepatic encephalopathy, hepatorenal syndrome, and infection. ConclusionTBil, PTA, Na+, TC, CTP score, age ≥50 years, the presence of liver cirrhosis, bilirubin-enzyme separation, and complications are independent risk factors for the prognosis of patients with HBV-related acute-on-chronic liver failure.

    Acute on chronic liver failure (ACLF) is rarely the initial manifestation of a malignant process or precipitated by the initiation of anti-viral treatment with a nucleoside or nucleotide agent. We report an unusual case of ACLF temporally associated with initiation of Entecavir for treatment of chronic hepatitis B. Early Hodgkin's lymphoma (HL) was unmasked with initiation of the anti-viral treatment which may have exacerbated ACLF. To the best of our knowledge, this has not been described in the literature. In reviewing our patients clinical course and liver autopsy, he developed a severe acute exacerbation of his chronic hepatitis B virus coinciding with the institution of antiviral therapy and the underlying HL perhaps modulating the overall degree of hepatic injury.

    Acute liver failure caused by hepatitis E virus genotype 3 and 4 has been rarely described. Because of the presence of a short golden therapeutic window in patients with viral acute liver failure from other causes, it is possible that early recognition and treatment might reduce the morbidity and mortality. We performed a systematic review and pooled analysis of acute liver failure caused by hepatitis E virus genotype 3 and 4. Two reviewers appraised studies after searching multiple databases on June 12th, 2017. Appropriate tests were used to compare hepatitis E virus genotype 3 vs 4, suspected vs confirmed genotypes, hepatitis E virus-RNA positive vs negative, and to discern important mortality risk factors. We identified 65 patients, with median age 58 years (range: 3-79), and a male to female ratio of 1.2:1. The median bilirubin, ALT, AST and alkaline phosphatase (expressed by multiplication of the upper limit of normal) levels were 14.8, 45.3, 34.8 and 1.63 respectively. Antihepatitis E virus IgG, antihepatitis E virus IgM and hepatitis E virus-RNA were positive in 84%, 91% and 86% of patients respectively. The median interval from symptoms onset to acute liver failure was 23 days, and 16 patients underwent liver transplantation. Final outcome was reported in 58 patients and mortality was 46%. Age was a predictor of poor prognosis in multivariate analysis. No important differences were found between patients infected with genotype 3 vs 4, patients with confirmed vs suspected genotypes, or patients with positive vs negative RNA. Acute liver failure caused by hepatitis E virus genotype 3 and 4 is rare, similar between genotypes, occurs commonly in middle-aged/elderly patients and has a very high mortality. Age is predictive of poor prognosis in multivariate analysis. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  18. Acute-on-chronic Liver Failure.

    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.

    Hepatitis A viral infection is a well-known cause of subclinical or acute self-limited hepatitis. Few cases of hepatitis A virus (HAV)-associated acute liver failure (ALF) have been reported in low HAV endemic countries annually. To investigate the possible factors that affected the severity of HAV infection, a family cluster infected with the HAV subgenotype IB strain, which is not common in Japan, was described. This family consisted of five members who all were infected with HAV. Four of the five patients hospitalized except for an asymptomatic patient. Two of the five patients, men in their 50s and 60s, developed ALF, and one patient died. Various host factors, including sex (male), age, and a high bilirubin level, may affect the outcomes. Based on viral factors, HAV RNA was higher in the fatal case compared with others, and it decreased within a short period of time. The similarity of the nucleotide sequences was 99.9% among the HAV isolates based on an entire genomic sequence. Deletions and/or insertions on the HAV protein-coding sequences that caused a frameshift were found in surviving cases but not in the fatal case. The rapid clearance of increased HAV and the absence of defective HAV might be closely associated with the onset of liver failure.

    Objective: To determine fetomaternal outcome in pregnant women with acute hepatitis E in terms of pregnancy outcome and perinatal mortality. Study Design: Case series. Place and Duration of Study: Department of Obstetrics and Gynecology, Sir Ganga Ram Hospital, Lahore, from July 2012 to March 2013. Methodology: Serum samples of 38 patients who presented with jaundice in pregnancy were collected to detect hepatitis E IgM antibodies. Demographics, pregnancy outcome and perinatal mortality was noted in hepatitis E positive cases with cause of complications. Cases with jaundice due solely to any other cause were excluded. Results: Twenty five patients had acute hepatitis E with coexistent acute hepatitis A in 1(4%) patient. Their mean age was 25 years and mean gravidity was 2. Among them, 10 (40%) patients were primigravida followed by gravida two in 7 (28%) cases. Twenty four (96%) patients presented in third trimester of pregnancy and in 1 (4%) pregnancy ended in second trimester missed miscarriage. The mean gestational age was 32 weeks. Twenty one (84%) babies were born alive, among them 18 (86%) were preterm. Perinatal mortality was 26%; contributed by intrauterine deaths and early neonatal deaths in 3 (14%) cases each. Total maternal deaths were 5 (20%), 4 (80%) in postpartum period and 1 (20%) in antepartum period due to fulminant hepatic failure in all cases. Conclusion: Prematurity in newborns and fulminant hepatic failure in mothers are major cause of poor fetomaternal outcome in acute hepatitis E in pregnancy. (author)

    To investigate the impact of the baseline status of patients with hepatitis B virus-associated acute-on-chronic liver failure on short-term outcomes. A retrospective study was conducted that included a total of 138 patients with hepatitis B virus-associated acute-on-chronic liver failure admitted to the Department of Infectious Diseases, Taihe Hospital, Hubei University of Medicine, from November 2013 to October 2016. The patients were divided into a poor prognosis group (74 patients) and a good prognosis group (64 patients) based on the disease outcome. General information, clinical indicators and prognostic scores of the patients' baseline status were analyzed, and a prediction model was established accordingly. Elder age, treatment with artificial liver support systems and the frequency of such treatments, high levels of white blood cells, neutrophils, neutrophil count/lymphocyte count ratio, alanine aminotransferase, gamma-glutamyl transferase, total bilirubin, urea, and prognostic scores as well as low levels of albumin and sodium were all significantly associated with the short-term outcomes of hepatitis B virus-associated acute-on-chronic liver failure. The predictive model showed that logit (p) = 3.068 + 1.003 × neutrophil count/lymphocyte count ratio - 0.892 × gamma-glutamyl transferase - 1.138 × albumin - 1.364 × sodium + 1.651 × artificial liver support therapy. The neutrophil count/lymphocyte count ratio and serum levels of gamma-glutamyl transferase, albumin and sodium were independent risk factors predicting short-term outcomes of hepatitis B virus-associated acute-on-chronic liver failure, and the administration of multiple treatments with artificial liver support therapy during the early stage is conducive to improved short-term outcomes.

    AIM: To describe the outcome and prognosis in a cohort of patients with acute liver failure due to autoimmune hepatitis without liver transplantation. METHODS: A retrospective trial was conducted in 11 patients with acute liver failure due to autoimmune hepatitis who attended the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubiran. 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. PMID:17465474

    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. Copyright © 2012 Wiley Periodicals, Inc.

    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.

    Clinical manifestations of hepatitis A virus (HAV) infection vary from mild to fulminant hepatic failure (FHF) in adults. We investigated the relationship between laboratory findings, including viral load, and clinical outcomes in patients with acute hepatitis A (AHA) and evaluated predictive factors for severe acute hepatitis (s-AH). We analyzed the clinical manifestations of AHA in 770 patients. Patients with a prothrombin time (PT) of less than 40% of normal were classified as s-AH and included 4 patients with FHF, 11 patients with acute renal failure, and 3 patients with prolonged jaundice (n = 128). Other patients were defined as mild acute hepatitis (m-AH) (n = 642). Serum samples were obtained from 48 patients with acute hepatitis A. Among them, 20 with s-AH, and 28 with m-AH, were tested for HAV RNA titer. In a multivariate analysis, age (HR = 1.042, P = 0.041), peak creatinine (HR = 4.014, P = 0.001), bilirubin (HR = 1.153, P = 0.003), alanine aminotransferase (ALT) (HR = 1.001, P hepatitis A.

    Full Text Available Adenoviruses are a common cause of respiratory infection, pharyngitis, and conjunctivitis in infants and young children. They are known to cause hepatitis and liver failure in immunocompromised patients; they are a rare cause of hepatitis in immunocompetent patients and have been known to cause fulminant hepatic failure. We present a 23-month-old immunocompetent infant who presented with acute noncholestatic hepatitis, hypoalbuminemia, generalized anasarca, and pancytopenia secondary to adenovirus infection.

    Full Text Available Abstract Introduction Cytomegalovirus generally causes self-limited, mild and asymptomatic infections in immunocompetent patients. An aggressive course in immunocompetent healthy patients is unusual. Case presentation We report the case of an immunocompetent 16-year-old Egyptian boy with encephalitis, acute renal failure, and acute hepatitis triggered by viral infection with a complete recovery following antiviral treatment. Conclusion We believe that this case adds to the understanding of the molecular biology, clinical presentation and increasing index of suspicion of many viral infections.

    Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

    Hepatitis B virus (HBV) has been classified into 8 genotypes that have different geographic distributions. The clinical outcomes of acute hepatitis are dependent on genotype. The aim of this study was to investigate the distribution of HBV subgenotypes and basal core promoter (BCP)/precore (PC) regions in acute hepatitis patients in Central Vietnam to clarify the distributions and the clinical and virological differences. 27 patients with acute hepatitis B were studied. HBV subgenotypes and BCP/PC variants were determined by direct sequencing of the preS, BCP/PC regions, respectively. HBV subgenotypes B4/Ba (n = 22) and C1/Cs (n = 5) were detected. Of the 27 patients, 3 developed fulminant hepatic failure, and all were infected with B4/Ba. Three patients had a BCP mutation, and 10 patients had a PC mutation in subgenotype B4/Ba. Three patients with C1/Cs had a BCP mutation. Two of 3 patients who progressed to fulminant hepatic failure had T1762, A1764, and A1896 simultaneously. None of the patients with acute, self-limited hepatitis carried these triple mutations. The prevalent HBV subgenotypes in patients with acute hepatitis B in Central Vietnam were B4/Ba and C1/Cs. BCP/PC variants have an association with the development of fulminant hepatic failure in subgenotype B4/Ba. Copyright 2009 S. Karger AG, Basel.

    Acute viral hepatitis (AVH) is a major public health problem and is an important cause of morbidity and mortality. The aim of the present study is to determine the prevalence of hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and hepatitis E virus (HEV) as causes of AVH in a tertiary care hospital of North India. Blood samples and clinical information was collected from cases of AVH referred to the Grade I viral diagnostic laboratory over a 1-year period. Samples were tested for hepatitis B surface antigen, anti-HCV total antibodies, anti-HAV immunoglobulin M (IgM) and anti-HEV IgM by the enzyme-linked immunosorbent assay. PCR for nucleic acid detection of HBV and HCV was also carried out. Those positive for HBV infection were tested for anti-HDV antibodies. Fisher's exact test was used and a P hepatitis cases, 62 (23.22%) patients presented as acute hepatic failure. HAV (26.96%) was identified as the most common cause of acute hepatitis followed by HEV (17.97%), HBV (16.10%) and HCV (11.98%). Co-infections with more than one virus were present in 34 cases; HAV-HEV co-infection being the most common. HEV was the most important cause of acute hepatic failure followed by co-infection with HAV and HEV. An indication towards epidemiological shift of HAV infection from children to adults with a rise in HAV prevalence was seen. To the best of our knowledge, this is the first report indicating epidemiological shift of HAV in Uttar Pradesh.

    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. © 2014 The Authors.

    Acute liver failure is rare in pediatric patients and is one of the most challenging medical emergencies due to its prognostic and therapeutic implications. The best scientific evidence worldwide comes from multicenter studies in developed countries. In Cuba, there are no prior studies of this disorder in children. Describe the main clinical features of Cuban children treated at a national referral center for acute liver failure, as defined by recognized diagnostic criteria for pediatric patients. A case series study was conducted comprising patients diagnosed with acute liver failure treated from 2005 to 2011 in the hepatology and liver transplant service at Havana's William Soler University Children's Hospital. Variables were age group, etiology of acute liver failure, grade of hepatic encephalopathy, blood chemistry variables, and clinical outcome (whether or not spontaneous recovery of liver function occurred). Associations between variables were assessed using contingency tables, and case fatality was calculated, as well as relative risk with its 95% confidence interval. The Mann-Whitney U test was used to compare means of laboratory test results. Median age of the 31 patients studied (14 boys and 17 girls) was 24 months (range 1-180). Time between symptom onset and diagnosis of acute liver failure was 25.1 days (SD 16.8). Infection was the most common etiology, present in 61.3% of cases (19/31); nonhepatotropic viruses, especially cytomegalovirus, predominated in infants. Spontaneous recovery occurred in 15 patients (48.4%), 3 (9.7%) received transplants, and 13 died, for a case fatality of 41.9%. Outcome was not associated with etiology (p = 0.106), but was statistically associated with degree of hepatic encephalopathy (p failure in Cuban children calls for further epidemiologic study and identification of local underlying determinants of this phenomenon.

    Full Text Available A 62-year-old male was sent to the emergency room due to a high fever and generalized skin rash after taking allopurinol for 9 days. Physical examination was normal except for the generalized skin rash presenting with erythematous macules. Complete blood count showed leukocytosis with eosinophilia. Blood biochemistry showed impaired renal and hepatic function. Pathologic examination concluded that the skin rash was erythema multiforme. These findings met the diagnostic criteria for allopurinol-induced hypersensitivity syndrome (AHS. Our patient not only had the most common skin lesion but soon developed acute renal failure that required intermittent hemodialysis, despite rapid discontinuation of allopurinol and adequate hydration and steroid therapy. No other causes of acute renal failure were found. Renal impairment was the worst part of the patient's condition and he never completely recovered. AHS should be considered in the differential diagnosis of acute renal and hepatic failure in patients with evidence of allergy and recent use of allopurinol.

    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. PMID:27574545

    Acute hepatitis A and E are recognized triggers of hepatic decompensation in patients with cirrhosis, particularly from the Indian subcontinent. However, the resulting acute-on-chronic liver failure (ACLF) has not been well characterized and no large studies are available. Our study aimed to evaluate the clinical profile and predictors of 3-month mortality in patients with this distinctive form of liver failure. ACLF was diagnosed in patients with acute hepatitis A or E [abrupt rise in serum bilirubin and/or alanine aminotransferase with positive immunoglobulin M anti-hepatitis A virus (HAV)/anti-hepatitis E virus (HEV)] presenting with clinical evidence of liver failure (significant ascites and/or hepatic encephalopathy) and clinical, biochemical, endoscopic (oesophageal varices at least grade II in size), ultrasonographical (presence of nodular irregular liver with porto-systemic collaterals) or histological evidence of cirrhosis. Clinical and laboratory profile were evaluated, predictors of 3-month mortality were determined using univariate and multivariate logistic regression and a prognostic model was constructed. Receiver-operating curves were plotted to measure performance of the present prognostic model, model for end-stage liver disease (MELD) score and Child-Turcotte-Pugh (CTP) score. ACLF occurred in 121 (3.75%) of 3220 patients (mean age 36.3+/-18.0 years; M:F 85:36) with liver cirrhosis admitted from January 2000 to June 2006. It was due to HEV in 80 (61.1%), HAV in 33 (27.2%) and both in 8 (6.1%). The underlying liver cirrhosis was due to HBV (37), alcohol (17), Wilson's disease (8), HCV (5), autoimmune (6), Budd-Chiari syndrome (2), haemochromatosis (2) and was cryptogenic in the rest (42). Common presentations were jaundice (100%), ascites (78%) and hepatic encephalopathy (55%). Mean (SD) CTP score was 11.4+/-1.6 and mean MELD score was 28.6+/-9.06. Three-month mortality was 54 (44.6%). Complications seen were sepsis in 42 (31.8%), renal failure in

    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. - Highlights: • The murine APAP model is very close to what is observed in patients. • The Gal/ET model is useful to study TNFα-mediated apoptotic signaling mechanisms. • Fas receptor activation is an effective model of apoptosis and secondary necrosis. • The ConA model is a relevant model of auto-immune hepatitis and viral hepatitis. • Multiple time point evaluation needed in experimental models of acute liver injury.

    Dengue is a common arboviral infection with a clinically diverse spectrum of presentations. Although hepatic dysfunction is commonly identified in patients will dengue illness, acute liver failure is rare. The etiopathogenesis of hepatic dysfunction is multifactorial and related to direct viral invasion of hepatocytes, immunological factors and hypoxia particularly in cases of shock in dengue hemorrhagic fever. Ideal management of dengue-related hepatic dysfunction and acute liver failure is still debated. We report a 53-year-old Sri Lankan Sinhalese male with serologically confirmed dengue fever presenting with evidence of plasma leakage developing acute liver failure evidenced by deranged liver functions, coagulopathy and altered sensorium. In addition to the 'standard care', the patient was managed with intravenous N-acetyl cysteine and blood transfusions even in the absence of bleeding or dropping packed cell volume (PCV), targeting a higher PCV in anticipation of better oxygenation at tissue level. He made a full recovery with no sequential infections. N-acetyl cysteine and packed cell transfusion aiming at a higher PCV to maintain adequate tissue perfusion during shock may be beneficial in acute liver failure due to dengue virus. Large randomized trials should be carried out to establish the efficacy of these treatment strategies to support these observations and change the current practice.

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

    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.

    The relevance of acute hepatitis E virus (HEV) infections has been underestimated for a long time. In the past, HEV infection had been interpreted falsely as a disease limited to the tropics until the relevance of autochthonous HEV infections in the Western world became overt. Due to increased awareness, the incidence of diagnosed autochthonous HEV infections (predominantly genotype 3) in industrialized countries has risen within the last decade. The main source of infections in industrialized countries seems to be infected swine meat, while infections with the tropical HEV genotypes 1 and 2 usually are mainly transmitted fecal-orally by contaminated drinking water. In the vast majority of healthy individuals, acute HEV infection is either clinically silent or takes a benign self-limited course. In patients who develop a symptomatic HEV infection, a short prodromal phase with unspecific symptoms is followed by liver specific symptoms like jaundice, itching, uncoloured stool and darkened urine. Importantly, tropical HEV infections may lead to acute liver failure, especially in pregnant women, while autochthonous HEV infections may lead to acute-on-chronic liver failure in patients with underlying liver diseases. Immunosuppressed individuals, such as transplant recipients or human immunodeficiency virus (HIV)-infected patients, are at risk for developing chronic hepatitis E, which may lead to liver fibrosis and cirrhosis in the long term. Importantly, specific treatment options for hepatitis E are not approved by the regulation authorities, but off-label ribavirin treatment seems to be effective in the treatment of chronic HEV-infection and may reduce the disease severity in patients suffering from acute liver failure.

    Parvovirus B19 infection is associated with a broad spectrum of clinical manifestations among which some are well known but others remain controversial. The role of this infection as a cause of acute hepatitis or exacerbation of chronic liver disease requires discussion regarding its significance in a strategy of prevention and treatment of patients with chronic hepatitis. Clinical importance of this infection in patients with chronic hepatitis B treated with pegylated interferon alpha 2a is still unclear but exactly in this population significant complications during treatment may arise. Parvovirus B19 infection is not rare among persons with chronic hepatitis B, therefore searching for co-infection should be placed in standard diagnostic procedures especially in case of exacerbation of chronic hepatitis, pancytopaenia or anaemia of unknown origin. Pegylated interferon alpha 2a still remains a gold standard of therapy of patients with chronic hepatitis B according to European (EASL) and Polish guidelines. We present a case of 35 years old woman treated with pegylated interferon alpha 2a who developed acute liver failure in 23rd week of chronic hepatitis B therapy. An exacerbation of hepatitis with encephalopathy and pancytopaenia have been observed. Parvovirus B19 and HBV co-infection does not increase the frequency of liver function abnormalities in patients with chronic hepatitis B. Further investigations should be done to describe the natural course of co-infection with parvovirus B19 and HBV and to establish possible association between parvovirus B19 infection and chronic hepatitis B and also the influence of interferon alpha 2a on the infections course.

    2009-12-01

    Full Text Available Abstract Congestive heart failure as a cause of acute liver failure is rarely documented with only a few cases. Although the pathophysiology is poorly understood, there is rising evidence, that low cardiac output with consecutive reduction in hepatic blood flow is a main causing factor, rather than hypotension. In the setting of acute liver failure due to congestive heart failure, clinical signs of the latter can be absent, which requires an appropriate diagnostic approach. As a reference center for acute liver failure and liver transplantation we recorded from May 2003 to December 2007 202 admissions with the primary diagnoses acute liver failure. 13/202 was due to congestive heart failure, which was associated with a mortality rate of 54%. Leading cause of death was the underlying heart failure. Asparagine transaminase (AST, bilirubin, and international normalized ratio (INR did not differ significantly in surviving and deceased patients at admission. Despite both groups had signs of cardiogenic shock, the cardiac index (CI was significantly higher in the survival group on admission as compared with non-survivors (2.1 L/min/m2 vs. 1.6 L/min/m2, p = 0.04. Central venous - and pulmonary wedge pressure did not differ significantly. Remarkable improvement of liver function was recorded in the group, who recovered from cardiogenic shock. In conclusion, patients with acute liver failure require an appropriate diagnostic approach. Congestive heart failure should always be considered as a possible cause of acute liver failure.

    Hepatic encephalopathy (HE) is challenging to identify in children with acute liver failure and was not a requirement for enrollment into the Pediatric Acute Liver Failure Study Group (PALFSG). The outcomes of PALFSG participants presenting with and without HE are presented. PALFSG participants were classified based on daily assessment of HE during the first 7 days following study enrollment: group 1-never developed HE; group 2-no HE at enrollment with subsequent HE development; and group 3-HE at study enrollment. Clinical and biochemical parameters and outcomes of death, spontaneous recovery, or liver transplantation were compared between groups. Data from 769 PALFSG (54% boys; median age 4.2 years; range 0-17.9 years) participants were analyzed, with 277 in group 1 (36%), 83 in group 2 (11%), and 409 in group 3 (53%). Mortality occurred in 11% of all participants and was highest among group 3 participants who demonstrated persistent grade III-IV HE (55%) or showed progression of HE (26%). Eleven (4%) group 1 participants died within 21 days of enrollment. Spontaneous recovery was highest in group 1 (79%) and lowest in group 2 (25%; P liver failure prognostication schema are needed.

    Various studies showed that entecavir (ETV) failed to improve the short-term survival in chronic hepatitis B (CHB) patients with severe acute exacerbation (SAE) and hepatic de-compensation or acute-on-chronic liver failure (ACLF). One study concluded that plasma exchange (PE) significantly decreased the short-term mortality of CHB patients with ACLF who were treated with lamivudine (LAM). Our study was designed to examine the effect of PE on CHB patients with ACLF who were treated with ETV. From August 2010 to January 2015, 38 (PE group) and 120 (control group) consecutive CHB-naïve patients with hepatic de-compensation and ACLF treated with PE plus ETV and ETV, respectively, were recruited. The primary endpoint was liver-related mortality at week 12. Biochemical and virological responses were also studied. At baseline, the PE group had higher serum alanine aminotransferase (ALT) levels and model for end-stage liver disease (MELD) scores, and had lower albumin levels than the control group. The cumulative survival rate at week 4 and week 12 in the PE group and control group were, respectively, 37 and 18 %, and 29 and 14 % (p  0.05). Univariate analysis showed that the control group had a higher liver-related mortality (p = 0.038) at week 12 than the PE group. Multivariate analysis showed that hepatic encephalopathy, ascites, PE treatment, and MELD scores were independent factors for liver-related mortality at week 12. PE significantly improved the short-term survival of CHB patients with hepatic de-compensation and ACLF who were treated with ETV. Hepatic encephalopathy, ascites, PE treatment, and MELD scores were independent factors for liver-related mortality at week 12.

    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.

    Hepatitis B virus (HBV)-related acute liver failure (HBV-ALF) may occur after acute HBV infection (AHBV-ALF) or during an exacerbation of chronic HBV infection (CHBV-ALF). Clinical differentiation of the two is often difficult if a previous history of HBV is not available. Quantitative measurements...... 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

    Objective: To determine prognostic indicators for morbidity and mortality in patients with fulminant hepatic failure. Design: Observational study. Place and Duration of Study: Department of Gastroenterology and Hepatology, Shaikh Zayed Postgraduate Medical Institute, Lahore, from April 2003 to June 2005. Patients and Methods: Forty-five patients with confirmed diagnosis of fulminant hepatic failure were included in this study. They were investigated for acute viral serology, complete blood count, liver function tests, renal function tests, serum electrolytes, arterial blood gases, initially daily and then on alternate days. Patients were followed in high dependency/ICU at the Shaikh Zayed Postgraduate Medical Institute. Data were analyzed by logistic regression analysis to identify predictors of mortality and morbidity. Results: Of the 45 subjects, 31 were males and 14 females. Twenty-four patients were positive for acute hepatitis E. Twenty patients recovered fully, whereas 25 died with mortality rate of 55.6 %. Variables i.e. presence of non-A non-B viral hepatitis, serum creatinine > 2.0 mg/dl, serum phosphate> 3.5 mg/dl and sepsis were found to have significant association with mortality on linear correlation. Only serum creatinine more than 2.0 mg/dl, serum phosphate > 3.5 mg/dl and development of sepsis were found to predict the outcome after multivariate analysis. Conclusion: Patients with serum creatinine > 2.0 mg/dl, serum phosphate > 3.5 mg/dl and sepsis showed adverse prognosis for survival. (author)

    Full Text Available Background: Acute viral hepatitis E (AVH-E can often result in acute liver failure (ALF during pregnancy. microRNAs serve as mediators in drug induced liver failure. We investigated their role as a biomarker in predicting ALF due to HEV (ALF-E. Methods: We performed next generation sequencing and subsequent validation studies in PBMCs of pregnant (P self limiting AVH-E, ALF due to HEV (ALF-E and compared with AVH-E in non-pregnant (NP females and healthy controls. Findings: Eleven microRNAs were significantly expressed in response to HEV infection; importantly, miR- 431, 654, 1468 and 4435, were distinctly expressed in pregnant self-limiting AVH-E and healthy females (p = 0.0005, but not in ALF-E. Sixteen exclusive microRNAs differentiated ALF-E from self limiting AVH-E in pregnant females. miR-450b which affects cellular proliferation and metabolic processes through RNF20 and SECB was predominanlty upregulated and correlated with poor outcome (ROC 0.958, p = 0.001. Interpretation: Our results reveal that a specific microRNA profile can predict fatality in ALF-E in pregnancy. These microRNAs could be exploited as prognostic biomarkers and help in the development of new therapeutic interventions. Keywords: Health sciences, Virology

  14. Acute Liver Failure Secondary to Niacin Toxicity

    Full Text Available A 17-year-old male was transferred to the pediatric intensive care unit for evaluation of acute liver failure. He was recently released from an alcohol treatment center with acute onset of chest pain. Cardiac workup was negative but he was found to have abnormal coagulation studies and elevated liver transaminases. 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.

    A teenager was admitted to an outside hospital ED following an episode of melena. He had been complaining of intermittent abdominal pain, nausea, malaise, and easy fatigability for 2 months, with significant worsening of symptoms 2 weeks prior to this episode. He had no significant medical, surgical, or family history. On presentation at the outside ED, he was found to be profoundly icteric and encephalopathic. Initial laboratories suggested anemia, acute kidney injury, and acute liver failure, leading to a presumptive diagnosis of acute fulminant liver failure necessitating transfer to our institution.

    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.

    Full Text Available Endothelin receptor antagonists are commonly used in the treatment of pulmonary hypertension. Sitaxsentan, a selective endothelin A receptor blocker, induces a mild transaminitis in approximately 3% to 5% of patients, but rarely an acute severe hepatitis. A case involving a 61-year-old female with sitaxsentan-induced acute severe liver failure is presented. Depite withdrawal of therapy, her liver tests failed to improve. After six weeks of monitoring, the patient was administered high-dose corticosteroids, with a good clinical and biochemical response. While endothelin receptor antagonists are postulated to cause hepatitis by inhibition of a bile salt transporter pump, an immune-mediated or idiosyncratic mechanism should be considered.

    To determine the etiology, clinical features and outcome of fulminant hepatic failure in pregnancy. An observational hospital based study was conducted at Isra University hospital Hyderabad from 1st March 2009 to 28th February 2010. Total 1192 obstetric patients were admitted in obstetrics & gynaecology department during this period, of whom 52 were with Fulminant hepatic failure in pregnancy and were included in this study. A pre-designed structured proforma was used. All patients had clinical history and underwent a physical examination. Routine laboratory tests, liver function tests and viral serology were performed in all cases. All results were analyzed on statistical software SPSS version 11. Frequencies and percentages were calculated, the final outcome was recorded. Out of 52, 6 (11.5%) presented in the first trimester, 4 (7.6%) in the second trimester and 42 (80.7%) were in their 3rd trimester of pregnancy. Etiology of the disease was Hepatitis E in 28 (53.8%), Hepatitis B in 9 (17.3%), Hepatitis C in 7 (13.5%) HELLP syndrome in 7 (13.5%) and acute fatty liver of pregnancy in 1 (3.57%) case. Maternal mortality was 15 (28.8%) and foetal mortality was 40 (77%). Only 12 (23.1%) new born remained alive. Fulminant hepatic failure in pregnancy has very high foetal and maternal mortality which is mostly due to viral hepatitis E.

    Objective: To determine the causes, characteristics and predictors of mortality in patients with acute-on-chronic liver failure (ACLF). Study Design: Cross-sectional study. Place and Duration of Study:Department of Hepatogastroenterology, Sindh Institute of Urology and Transplantation, Karachi, from July 2014 to June 2016. Methodology:All patients with acute-on-chronic liver disease (ACLD) with ages > 12 were included. Patients with ACLF, as defined by the Asian Pacific Association for the Study of Liver (APASL, 2014) were identified. Predictors of mortality were identified using chi-square or Fisher's exact test. Results: Included in the study were 72 patients with mean age of 36.71 years, 46 (63.9%) being males. Among them, 61 developed ACLF. Commonest causes of chronic liver disease (CLD) were chronic viral hepatitis (37, 51.4%) and autoimmune hepatitis (14, 19.4%). Commonest causes of acute liver injury (ALI) were acute viral hepatitis (24, 33.3%) and drug induced liver injury (DILI) (17, 23.6%). Among those with ACLF, 24 (39.3%) patients died with median survival of 17.1 +-13.5 days. Mortality was significantly associated with Child Turcotte Pugh (CTP) score =>13 (p=0.010), model for end-stage liver disease (MELD) score =>30 (p=0.001), age >40 years (p=0.036), organ failures (OF) =>3 (p 3, CTP =>13, MELD =>30, age >40 years, PSE, renal failure and urosepsis.

    Alcoholic hepatitis (AH) causes great morbidity and mortality in the United States and throughout the world. Advances in therapy have proven difficult. In part, this reflects challenges in diagnosis, including the distinction between AH and acute-on-chronic liver failure. Liver biopsy is the best method to clarify the cause in circumstances whereby conflicting clinical data confound the diagnosis. All treatment of AH begins with abstinence from alcohol. All patients with AH should be given sufficient nutrition. Prednisolone has become the principal agent for treating patients with severe AH. Copyright © 2016 Elsevier Inc. All rights reserved.

    To study Chinese syndrome typing of acute hepatic failure (AHF) mice model by screening effective formulae. Lipoplysaccharides (LPS)/D-galactosamine (D-GaIN) was intraperitoneally injected to mice to establish the AHF mice model. Yinchenhao Decoction, Huanglian Jiedu Decoction, Buzhong Yiqi Decoction, and Xijiao Dihuang Decoction were administered to model mice respectively by gastrogavage. The behavior and the survival rate were monitored. The liver function and pathological changes of liver tissues were detected. In all the tested classic recipes, the survival rate was elevated from 10% to 60% by administration of Xijiao Dihuang Decoction. Five h after modeling, the serum alanine aminotransferase (ALT) level was (183.95 +/- 52.00) U/L, and aspartate aminotransferase (AST) (235.70 +/- 34.03) U/L in Xijiao Di-huang Decoction Group, lower than those of the model control group, but with insignificant difference (ALT: 213.32 +/- 71.93 U/L; AST: 299.48 +/- 70.56 U/L, both P > 0.05). Xijiao Dihuang Decoction could obviously alleviate the liver injury. Xijiao Dihuang Decoction was an effective formula for LPS/D-GaIN induced AHF model. According to syndrome typing through formula effect, heat toxin and blood stasis syndrome dominated in the LPS/D-GalN induced AHF mice model.

    Liver scintigraphy was performed in 12 cases with fulminant hepatitis, in 8 cases with severe acute hepatitis and in 44 cases with acute hepatitis. Scintiphotoes of severe hepatitis showed reduction of liver size, marked visualization of the bone marrow and the spleen, so this pattern was useful to differentiate from acute hepatitis. Relative size of the liver calculated by A.L.I. (anterior liver index) showed significant reduction in severe hepatitis compared with that of acute hepatitis. Three of five patients with died of severe hepatitis showed high uptake in the lung and ribs, but none of fifteen patients with severe hepatitis who recovered showed the abnormal accumulation in the lung and in the ribs.

    Genetic variation within hepatitis B surface antigen (HBsAg), in particular within the major hydrophobic region (MHR), is related to immune/vaccine and test failures and can have a significant impact on the vaccination and diagnosis of acute infection. This study shows, for the first time, variation among acute cases and compares the amino acid variation within the HBsAg between acute and chronic infections. We analyzed the virus isolated from 1231 acute and 585 chronic cases reported to an anonymized public health surveillance database between 2004 and 2014 in The Netherlands. HBsAg analysis revealed the circulation of 6 genotypes (Gt); GtA was the dominant genotype followed by GtD among both acute (68.2% and 17.4%, respectively) and chronic (34.9% and 34.2%, respectively) cases. Variation was the highest among chronic strains compared to that among acute strains. Both acute and chronic GtD showed the highest variation compared to that of other genotypes (P < .01). Substitutions within the MHR were found in 8.5% of the acute strains and 18.6% of the chronic strains. Specific MHR substitutions described to have an impact on vaccine/immune escape and/or HBsAg test failure were found among 4.1% of the acute strains and 7.0% of the chronic strains. In conclusion, we show a high variation of HBsAg among acute and chronic hepatitis B virus-infected cases in The Netherlands, in particular among those infected with GtD, and compare, for the first time, variation in frequencies between acute and chronic cases. Additional studies on the impact of these variations on vaccination and test failure need to be conducted, as well as whether HBsAg false-negative variants have been missed. © 2018 The Authors.

    The purpose of this study was to characterize the incidence, clinical features, and prognosis of acute pancreatitis in cats with hepatic lipidosis. Of 13 cats histologically diagnosed with hepatic lipidosis between July 1988, and November 1989, 5(38%) were also histologically diagnosed with acute pancreatitis. In cats with hepatic lipidosis alone, the signalment, history, physical examination, and clinicopathologic findings were generally indistinguishable from those of cats with concurrent acute pancreatitis except that cats with acute pancreatitis were more likely to be cachectic and to have coagulation abnormalities. Hepatomegaly was seen on abdominal radiographs in both groups. Of the 5 cats with concurrent acute pancreatitis, abdominal ultrasonography detected 1 cat with a hypoechoic pancreas and 5 with peritoneal effusion; those abnormalities were not seen in cats without concurrent acute pancreatitis. Cats with concurrent acute pancreatitis had only a 20% recovery rate, compared with a 50% recovery rate in cats with hepatic lipidosis alone. We conclude that cats with hepatic lipidosis should be rigorously evaluated for concurrent acute pancreatitis because of 1) the rate of disease coincidence, 2) the inability of signalment, history, physical examination, and clinicopathologic findings to adequately distinguish between hepatic lipidosis and acute pancreatitis, 3) the worse prognosis associated with concurrent acute pancreatitis, and 4) the opposing nutritional strategies for hepatic lipidosis and acute pancreatitis.

    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.

    Full Text Available ObjectiveTo observe the clinical effects of lamivudine antiviral therapy combined with plasma exchange in patients with acute-on-chronic hepatitis B liver failure. MethodsForty-seven patients (treatment group were administered lamivudine and underwent plasma exchange. An additional forty-five patients (control group were administered lamivudine but no plasma exchange. Otherwise, all patients received the same basic medical treatment. The two groups were further divided into three sub-groups according to the model for end-stage liver disease (MELD score: <30, 30-39, and ≥40. The significance of differences in survival rates between the groups and sub-groups was determined by the χ2 test. ResultsThe overall survival rate was significantly better in the treatment group (63.82% vs. control group: 44.44%; χ2=4.31, P<0.05. Within the treatment group, the survival rates were highest in the 30-39 MELD score sub-group (71.42%, which was significantly different from survival rate in the same sub-group of the controls (vs. 38.10%; χ2=4.71, P<005. The other two MELD score sub-groups showed no significant differences between the treatment and control groups (all P>0.05. ConclusionCombined therapy consisting of lamivudine treatment and plasma exchange can improve the survival rate of patients with acute-on-chronic hepatitis B liver failure who have MELD scores between 30 and 39.

    B19V has been proposed as an etiologic agent for hepatitis, mainly in children, but this is a rare clinical occurrence. In this article, we report a case of non-A-E acute liver failure in an immunocompetent child with B19 infection. The clinical findings of severe anemia and pancytopenia combined with the detection of anti-B19 Immunoglobulin G (IgG), B19 DNA and B19 mRNA in liver indicate a persistent infection and suggest a diagnosis of parvovirus B19-associated acute liver failure.

    Acute liver failure is a rapidly progressive deterioration of hepatic function resulting in high mortality and morbidity. Metabolic enzymes can translocate in the nucleus to regulate histone acetylation and gene expression. Levels and activities of pyruvate dehydrogenase complex (PDHC) and lactate dehydrogenase (LDH) were evaluated in nuclear fractions of livers of mice exposed to various hepatotoxins including CD95-Ab, α-amanitin, and acetaminophen. Whole-genome gene expression profiling by RNA-seq was performed in livers of mice with acute liver failure and analyzed by Gene Ontology Enrichment Analysis. Efficacy of histone acetyltransferase inhibitor garcinol and LDH inhibitor galloflavin at reducing liver damage was evaluated in mice with induced hepatotoxicity. Levels and activities of PDHC and LDH were increased in cytoplasmatic and nuclear fractions of livers of mice with acute liver failure. The increase of nuclear PDHC and LDH was associated with increased concentrations of acetyl-coA and lactate in nuclear fractions, and histone H3 hyper-acetylation. Gene expression in livers of mice with acute liver failure suggested that increased histone H3 acetylation induces the expression of genes related to response to damage. Reduced histone acetylation by the histone acetyltransferase inhibitor garcinol decreased liver damage and improved survival in mice with acute liver failure. Knock-down of PDHC or LDH improved viability in cells exposed to a pro-apoptotic stimulus. Treatment with the LDH inhibitor galloflavin that was also found to inhibit PDHC, reduced hepatic necrosis, apoptosis, and expression of pro-inflammatory cytokines in mice with acute liver failure. Mice treated with galloflavin also showed a dose-response increase in survival. PDHC and LDH translocate to the nucleus and are targets for therapy of acute liver failure. Acute liver failure is a rapidly progressive and life-threatening deterioration of liver function resulting in high mortality and

    Hepatic encephalopathy is a neuropsychiatric disorder of complex pathogenesis caused by acute or chronic liver failure. We investigated the effects of cannabidiol, a non-psychoactive constituent of Cannabis sativa with anti-inflammatory properties that activates the 5-hydroxytryptamine receptor 5-HT(1A) , on brain and liver functions in a model of hepatic encephalopathy associated with fulminant hepatic failure induced in mice by thioacetamide. Female Sabra mice were injected with either saline or thioacetamide and were treated with either vehicle or cannabidiol. Neurological and motor functions were evaluated 2 and 3 days, respectively, after induction of hepatic failure, after which brains and livers were removed for histopathological analysis and blood was drawn for analysis of plasma liver enzymes. In a separate group of animals, cognitive function was tested after 8 days and brain 5-HT levels were measured 12 days after induction of hepatic failure. Neurological and cognitive functions were severely impaired in thioacetamide-treated mice and were restored by cannabidiol. Similarly, decreased motor activity in thioacetamide-treated mice was partially restored by cannabidiol. Increased plasma levels of ammonia, bilirubin and liver enzymes, as well as enhanced 5-HT levels in thioacetamide-treated mice were normalized following cannabidiol administration. Likewise, astrogliosis in the brains of thioacetamide-treated mice was moderated after cannabidiol treatment. Cannabidiol restores liver function, normalizes 5-HT levels and improves brain pathology in accordance with normalization of brain function. Therefore, the effects of cannabidiol may result from a combination of its actions in the liver and brain. © 2011 The Authors.

    Objective: To determine the efficacy of N-acetylcysteine (NAC) in children aged > 1 month to 16 years admitted with Fulminant Hepatic Failure (FHF) secondary to Acute Viral Hepatitis (AVH) in a tertiary care center of a developing country. Study Design: Analytical study. Place and Duration of Study: Department of Paediatrics, The Aga Khan University Hospital, Karachi, Pakistan, from January 2007 to December 2011. Methodology: Medical records of children (> 1 month - 16 years) with FHF admitted with AVH of known etiology who received NAC were reviewed retrospectively. Liver function tests (mean ± SD) at baseline, 24 hours after NAC and before or at the time of discharge/death were recorded and compared via using repeated measures ANOVA(r-ANOVA). Efficacy of NAC is defined in improvement in biochemical markers, liver function test and discharge disposition (survived or died). Mortality associated risk factors were identified by using logistic regression analysis. P-value and 95 percentage confidence interval were recorded. Results: Forty children (mean age was 80 ± 40 months) with FHF secondary to AVH received NAC. Majority were males (n=25; 63 percentage). Vomiting (75 percentage) and jaundice (65 percentage) were the main presenting symptoms, one-third had hypoglycemic, while 40 percentage had altered sensorium at the time of admission. There was significant statistical difference in liver enzymes and prothrombin time on admission comparing at discharge in children received NAC (p < 0.001). Fifteen (38 percentage) children died. Severe vomiting (Odds Ratio (OR) 0.22, 95 percentage Confidence Interval (CI) 0.05 - 0.8), jaundice (OR 9.3, CI 1.1 - 82.6), inotropic support (OR 20.6, CI 3.5 - 118.3) and mechanical ventilation (OR 4.3, CI 1.1 - 16.6) at the time of admission are associated with risk factors for mortality in children with FHF secondary to AVH. Conclusion: NAC used in children with FHF secondary to AVH is associated with markedly improved liver function

    Full Text Available Objectives. To describe the clinical characteristics of patients presenting with fulminant liver failure after varying periods of exposure to Efavirenz containing antiretroviral medications. Methods. We report a series of 4 patients with human immunodeficiency virus (HIV infection who were admitted with acute liver failure (ALF over a 6-month period. All these patients had been treated with a range of Efavirenz containing antiretroviral regimens and were negative for hepatitis A, B, and C infections as well as other opportunistic infections, all were negative for autoimmune hepatitis, and none had evidence of chronic liver disease or use of alcohol or herbal medications. Information on patient clinical characteristics, current antiretroviral regimen, CD4 count, HIV-1 RNA levels, and clinical chemistry parameters was collected. Informed consent was provided. Results. During a 6-month period, four patients without other known risk factors for acute hepatitis presented with symptomatic drug-induced liver injury with varying symptoms and outcomes. The pattern of liver injury was hepatocellular for all the 4 cases. Liver biopsies were done for all the four cases and the results showed a heavy mixed inflammatory cell infiltrate with eosinophils. For three patients withdrawal of Efavirenz from their antiretroviral regimen was sufficient to restore transaminase levels to normal and led to improvement of clinical symptoms. For one patient his clinical course was characterized by fulminant liver failure and fluctuating episodes of hepatic encephalopathy which ultimately resulted in his death. Conclusion. Hepatotoxicity of Efavirenz is not as rare as previously described in the literature and does actually present with fatal outcomes. The key message to note is that frequent monitoring of liver enzymes should be done at initiation of antiretroviral therapy and should continue throughout the treatment period.

  19. Acute Liver Impairment in a Young, Healthy Athlete: Hypoxic Hepatitis and Rhabdomyolysis following Heat Stroke

    2012-08-01

    Full Text Available Any process that substantially diminishes arterial blood flow or arterial oxygen content to the liver can result in hypoxic (ischaemic hepatitis. 90% of hypoxic hepatitis occurs in unstable patients in intensive care units with haemodynamic failure secondary to heart failure, respiratory failure and toxic shock. The rate of in-hospital mortality in hypoxic hepatitis is very high with studies recording mortalities of 61.5%. It tends to be very uncommon in healthy, young patients with no underlying medical problems. We report here the case of a young healthy athlete who developed heat stroke associated with rhabdomyolysis and hypoxic hepatitis while he was running the final stages of a marathon. The patient required intensive care admission and inotropic support for a few hours after he was admitted with heat stroke. He underwent a rapid recovery after he was resuscitated with fluids. N-acetyl cysteine was also given during the acute stage of the hepatitis. This case highlights an uncommon case of hypoxic hepatitis in a young, healthy patient secondary to hypotension and heat stroke. Inotropic support might have precipitated the hypoxic hepatitis in this young patient.

    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.

    Spectral electroencephalogram analysis is a method for automated analysis of electroencephalogram patterns, which can be performed at the bedside. We sought to determine the utility of spectral electroencephalogram for grading hepatic encephalopathy in children with acute liver failure. Retrospective cohort study. Tertiary care pediatric hospital. Patients between 0 and 18 years old who presented with acute liver failure and were admitted to the PICU. None. Electroencephalograms were analyzed by spectral analysis including total power, relative δ, relative θ, relative α, relative β, θ-to-Δ ratio, and α-to-Δ ratio. Normal values and ranges were first derived using normal electroencephalograms from 70 children of 0-18 years old. Age had a significant effect on each variable measured (p liver failure were available for spectral analysis. The median age was 4.3 years, 14 of 33 were male, and the majority had an indeterminate etiology of acute liver failure. Neuroimaging was performed in 26 cases and was normal in 20 cases (77%). The majority (64%) survived, and 82% had a good outcome with a score of 1-3 on the Pediatric Glasgow Outcome Scale-Extended at the time of discharge. Hepatic encephalopathy grade correlated with the qualitative visual electroencephalogram scores assigned by blinded neurophysiologists (rs = 0.493; p encephalopathy was correlated with a total power of less than or equal to 50% of normal for children 0-3 years old, and with a relative θ of less than or equal to 50% normal for children more than 3 years old (p > 0.05). Spectral electroencephalogram classification correlated with outcome (p encephalopathy and correlates with outcome. Spectral electroencephalogram may allow improved quantitative and reproducible assessment of hepatic encephalopathy grade in children with acute liver failure.

  4. 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 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.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.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 in ALF, emphasizing the close relationship between

    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.

    Full Text Available Acute viral hepatitis affects all ages worldwide. Hepatitis E virus (HEV is increasingly recognized as a major cause of acute hepatitis in Europe. Because knowledge of its characteristics is limited, we conducted a retrospective study to outline demographic and clinical features of acute HEV in comparison to hepatitis A, B and C in Lothian over 28 months (January 2012 to April 2014. A total of 3204 blood samples from patients with suspected acute hepatitis were screened for hepatitis A, B and C virus; 913 of these samples were also screened for HEV. Demographic and clinical information on patients with positive samples was gathered from electronic patient records. Confirmed HEV samples were genotyped. Of 82 patients with confirmed viral hepatitis, 48 (59% had acute HEV. These patients were older than those infected by hepatitis A, B or C viruses, were more often male and typically presented with jaundice, nausea, vomiting and/or malaise. Most HEV cases (70% had eaten pork or game meat in the few months before infection, and 14 HEV patients (29% had a recent history of foreign travel. The majority of samples were HEV genotype 3 (27/30, 90%; three were genotype 1. Acute HEV infection is currently the predominant cause of acute viral hepatitis in Lothian and presents clinically in older men. Most of these infections are autochthonous, and further studies confirming the sources of infection (i.e. food or blood transfusion are required.

    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.)

    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

    2013-01-01

    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.

    2018-05-01

    Acute liver failure of all causes is diagnosed in between 2000 and 2500 patients annually in the United States. Drug-induced acute liver failure is the leading cause of acute liver failure, accounting for more than 50% of cases. Nonacetaminophen drug injury represents 11% of all cases in the latest registry from the US Acute Liver Failure Study Group. Although rare, acute liver failure is clinically dramatic when it occurs, and requires a multidisciplinary approach to management. In contrast with acetaminophen-induced acute liver failure, non-acetaminophen-induced acute liver failure has a more ominous prognosis with a lower liver transplant-free survival.

    To evaluate and compare MR and CT in diagnosis of acute traumatic hepatic laceration, ten patients with acute hepatic rupture underwent CT scan and/or MRI in the first 24 hours after injury. The injury was graded as mild ( 50% of one lobe). In the first 24 hours after injury, 33.3% (3/9) and 28.6%(2/7) of the hepatic injury demonstrated isodensity and isointensity on plain CT scan and T 1 -weighted images. All the lesions (100%) were clearly identified as marked hyperintensity on T 2 -weighted images. On T 2 WI, T 1 WI and non-contrast CT, 100%, 57.1% and 55.6% of the acute hepatic injuries could be graded respectively. Delayed complications occurred in four patients with deep hepatic injury about 1 to 3 weeks after injury. T 2 -weighted MR imaging is more sensitive and useful for detection of the type and severity of acute hepatic rupture. Follow-up MRI or CT within the first few weeks after injury is needed in patients with deep hepatic injury for detection of delayed complications

    The care of patients with acutely decompensated heart failure is being reshaped by the availability and understanding of several novel and emerging heart failure biomarkers. The gold standard biomarkers in heart failure are B-type natriuretic peptide and N-terminal pro-B-type natriuretic peptide, which play an important role in the diagnosis, prognosis, and management of acute decompensated heart failure. Novel biomarkers that are increasingly involved in the processes of myocardial injury, neurohormonal activation, and ventricular remodeling are showing promise in improving diagnosis and prognosis among patients with acute decompensated heart failure. These include midregional proatrial natriuretic peptide, soluble ST2, galectin-3, highly-sensitive troponin, and midregional proadrenomedullin. There has also been an emergence of biomarkers for evaluation of acute decompensated heart failure that assist in the differential diagnosis of dyspnea, such as procalcitonin (for identification of acute pneumonia), as well as markers that predict complications of acute decompensated heart failure, such as renal injury markers. In this article, we will review the pathophysiology and usefulness of established and emerging biomarkers for the clinical diagnosis, prognosis, and management of acute decompensated heart failure.

    Drug induced acute toxic hepatitis can be idiosyncratic. Albendazole, a widely used broad spectrum antiparasitic drug is generally accepted as a safe drug. It may cause asymptomatic transient liver enzyme abnormalities but acute toxic hepatitis is very rare. Case Report : Herein, we present the case of 47 year old woman with recurrent acute toxic hepatitis after a single intake of albendazole in 2010 and 2014. The patient was presented with symptoms and findings of anorexia, vomiting and jaundice. For diagnosis, other acute hepatitis etiologies were excluded. Roussel Uclaf Causality Assessment Method (RUCAM) score was calculated and found to be 10, which meant highly probable drug hepatotoxicity. Within 2 months, all pathological findings came to normal. There are a few reported cases of albendazole induced toxic hepatitis, but at adults, there is no known recurrent acute toxic hepatitis due to albendazole at this certainty according to RUCAM score. Physicians should be aware of this rare and potentially fatal adverse effect of albendazole. © Acta Gastro-Enterologica Belgica.

    Full Text Available Acute hepatitis is characterized by liver inflammation and liver cell necrosis. The most frequently observed underlying cause thereof is viruses, but various other causes, such as alcohol, medication, or toxins may also lead thereto.In this paper, a case of acute hepatitis presenting with bradycardia, hypotension, and a prominent increase in liver enzymes following mad honey ingestion is discussed. Since there are only few cases of acute hepatitis following mad honey ingestion in the literature, we want to present this subject matter.

    The purpose of this study was investigate the diagnostic value of liver scintigraphy, computed tomography (CT) and ultrasonography in acute hepatic failure, subacute hepatitis and acute hepatitis. By scintigraphy low uptake in the liver and high uptake in the spleen and bone marrow were observed in hepatic failure. However, uneven liver edge and heterogenous RI destribution were not corresponded to massive necrosis. In fulminant hepatitis, liver size and other findings were variable in patient by patient. But in subacute hepatitis, the findings were typical. The finding of left lobe swelling was observed in a half of patients with acute hepatic failure based on chronic hepatitis. Localized low density area by the CT was detected in most of the cases of subacute hepatitis, and acute hepatitis with submassive hepatic necrosis. But in fulminant hepatitis, that was rare. In these cases, irregular and strong lesion was also obsurved by ultrasonography. These findings by the CT and ultrasonography were corresponded to massive necrosis histrogically ultrasonography revealed narrowing of hepatic vein in fatal hepatitis. Localized low density area by the CT in subacute hepatitis was shown surrounding hepatic vein. We conclude that development of massine hepatic necrosis concern to secondary hepatic ischemia.

    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: 14*hepatic dysfunction + 11*cISS + 18*cUrea + 12*cGlucose + 10*pulmonary dysfunction. Optimal score cut-off for prediction of renal failure was found to be ≥25 with

    Acute hepatitis is a disorder that goes with liver cell necrosis and liver inflammation. Among the causes of acute hepatitis, the most common reasons are viral hepatitis. About 95% of the acute hepatitis generate because of hepatotropic viruses. Epstein-barr virus (EBV) and cytomegalovirus (CMV) are from the family of herpes viruses and rare causes of acute hepatitis. In this case report, acute hepatitis due to EBV and CMV coinfection will be described. Ates İ, Kaplan M, Yilmaz N, Çiftçi F.

    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.)

  6. Renal failure affects the enzymatic activities of the three first steps in hepatic heme biosynthesis in the acute intermittent porphyria mouse.

    Directory of Open Access Journals (Sweden)

    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.

  7. Curative Effects of Thiacremonone against Acetaminophen-Induced Acute Hepatic Failure via Inhibition of Proinflammatory Cytokines Production and Infiltration of Cytotoxic Immune Cells and Kupffer Cells

    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.

    Sporadic non-A, non-B hepatitis is the most common indication for liver transplantation in patients presenting with fulminant and subacute liver failure. This study used serological, histological, and molecular biological techniques to examine specimens from 23 consecutive patients transplanted for sporadic non-A, non-B hepatitis. No evidence was found of hepatitis C virus, hepatitis E virus, or 'cryptic' hepatitis B virus infection.

    In spite of the high incidence of hepatic encephalopathy (HE) in cirrhosis, there are few observational studies. We performed an analysis to define the characteristics of HE and associated features using the database of the Canonic Study. Clinical, laboratory and survival data of 1348 consecutive cirrhotic patients admitted with an acute decompensation were compared according to the presence (n=406) or absence of HE and of acute-on-chronic liver failure (ACLF) (n=301). HE development was independently associated with previous HE episodes; survival probabilities worsen in relation to the presence and grade of HE. There were marked differences between HE associated (n=174) and not associated (n=286) to ACLF. HE not associated with ACLF occurred in older cirrhotics, inactive drinkers, without severe liver failure or systemic inflammatory reaction and in relation to diuretic use. In contrast, HE associated with ACLF occurred in younger cirrhotics, more frequently alcoholics, with severe liver failure and systemic inflammatory reaction, and in relation to bacterial infections, active alcoholism and/or dilutional hyponatremia. Prognosis was relatively preserved in the first and extremely poor in the second group. Independent risk factors of mortality in patients with HE were age, bilirubin, INR, creatinine, sodium, and HE grade. In cirrhosis, previous HE identifies a subgroup of patients that is especially vulnerable for developing new episodes of HE. The course of HE appears to be different according to the presence of ACLF. Copyright © 2013 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.

    Acute liver failure (ALF) is frequently complicated by infection leading to precipitation of central nervous system complications such as hepatic encephalopathy (HE) and increased mortality. There is evidence to suggest that when infection occurs in ALF patients, the resulting pro-inflammatory mechanisms may be amplified that could, in turn, have a major impact on blood-brain barrier (BBB) function. The aim of this study was to investigate the role of endotoxemia on the progression of encephalopathy in relation to BBB permeability during ALF. Adult male C57-BL6 mice with ALF resulting from azoxymethane-induced toxic liver injury were administered trace amounts of the endotoxin component lipopolysaccharide (LPS). Effects on the magnitude of the systemic inflammatory response, liver pathology and BBB integrity were measured as a function of progression of HE, defined as time to loss of corneal reflex (coma). Lipopolysaccharide caused additional two- to seven-fold (P liver pathology and associated increases of circulating transaminases as well as increased hyperammonaemia consistent with a further loss of viable hepatocytes. LPS treatment of ALF mice led to a rapid precipitation of hepatic coma and the BBB became permeable to the 25-kDa protein immunoglobulin G (IgG). This extravasation of IgG was accompanied by ignificant up-regulation of matrix metalloproteinase-9 (MMP-9), an endopeptidase known to modulate opening of the BBB in a wide range of neurological disorders. These findings represent the first direct evidence of inflammation-related BBB permeability changes in ALF. © 2013 John Wiley & Sons A/S. Publishing by John Wiley & Sons Ltd.

  12. Amniotic-fluid-derived mesenchymal stem cells overexpressing interleukin-1 receptor antagonist improve fulminant hepatic 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.

    To establish a practical and reproducible animal model of human acute-on-chronic liver failure for further study of the pathophysiological mechanism of acute-on-chronic liver failure and for drug screening and evaluation in its treatment. Immunological hepatic fibrosis was induced by human serum albumin in Wistar rats. In rats with early-stage cirrhosis (fibrosis stage IV), D-galactosamine and lipopolysaccharide were administered. Mortality and survival time were recorded in 20 rats. Ten rats were sacrificed at 4, 8, and 12 hours. Liver function tests and plasma cytokine levels were measured after D-galactosamine/lipopolysaccharide administration and liver pathology was studied. Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay. Most of the rats treated with human albumin developed cirrhosis and fibrosis, and 90% of them died from acute liver failure after administration of D-galactosamine/lipopolysaccharide, with a mean survival time of (16.1+/-3.7) hours. Liver histopathology showed massive or submassive necrosis of the regenerated nodules, while fibrosis septa were intact. Liver function tests were compatible with massive necrosis of hepatocytes. Plasma level of TNFalpha increased significantly, parallel with the degree of the hepatocytes apoptosis. Plasma IL-10 levels increased similarly as seen in patients with acute-on-chronic liver failure. We established an animal model of acute-on-chronic liver failure by treating rats with human serum albumin and later with D-galactosamine and lipopolysaccharide. TNFalpha-mediated liver cell apoptoses plays a very important role in the pathogenesis of acute liver failure.

    2014-01-01

    Objectives. Because only a fraction of patients with acute viral hepatitis A, B, and C are reported through national surveillance to the Centers for Disease Control and Prevention, we estimated the true numbers. Methods. We applied a simple probabilistic model to estimate the fraction of patients with acute hepatitis A, hepatitis B, and hepatitis C who would have been symptomatic, would have sought health care tests, and would have been reported to health officials in 2011. Results. For hepatitis A, the frequencies of symptoms (85%), care seeking (88%), and reporting (69%) yielded an estimate of 2730 infections (2.0 infections per reported case). For hepatitis B, the frequencies of symptoms (39%), care seeking (88%), and reporting (45%) indicated 18 730 infections (6.5 infections per reported case). For hepatitis C, the frequency of symptoms among injection drug users (13%) and those infected otherwise (48%), proportion seeking care (88%), and percentage reported (53%) indicated 17 100 infections (12.3 infections per reported case). Conclusions. These adjustment factors will allow state and local health authorities to estimate acute hepatitis infections locally and plan prevention activities accordingly. PMID:24432918

  15. 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.

    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.

    Full Text Available Hepatitis E virus (HEV is a small RNA virus and the infectious agent of hepatitis E that occurs worldwide either as epidemics in Asia caused by genotype 1 and 2 or as sporadic disease in industrialized countries induced by genotype 3 and 4. The frequency might be underestimated in central Europe as a cause of acute hepatitis. Therefore, we analyzed on liver biopsies, if cases of acute hepatitis with clinically unknown or obscure diagnosis were actually caused by the infection with HEV.We included 221 liver biopsies retrieved from the files of the institute of pathology during the years 2000 till 2010 that were taken from patients with acute hepatitis of obscure or doubtful diagnosis. From all biopsies RNA was extracted, prepared, and subjected to RT-PCR with specific primers. Amplified RNA was detected in 7 patients, sequenced and the genotype 3 could be determined in four of the seven of positive specimens from 221 samples. Histopathology of the biopsies revealed a classic acute hepatitis with cholestatic features and in some cases confluent necrosis in zone 3. Histology in a cohort of matched patients was less severe and showed more eosinophils. The analysis of the immune response by subtyping of liver infiltrating lymphocytes showed circumstantial evidence of adaptive immune reaction with CD 8 positive CTLs being the dominant lymphocyte population.In conclusion, in doubtful cases of acute hepatitis of unknown origine hepatitis E virus infection should be considered as etiology in central Europe. We demonstrate for the first time that the diagnosis can be made in paraffin-embedded liver biopsies reliably when no serum is available and also the genotype can be determined. The analysis of the immune response by subtyping of liver infiltrating lymphocytes indicates an adaptive mechanism suggesting in analogy with HAV, HBV and HCV that the virus itself is not cytopathic but liver damage is due to immune reaction.

    We report a 61-year-old woman who was hospitalized because of abdominal pain in the right upper quadrant related to a liver tumor (ultrasound and tomographic findings). A collection of blood was obtained by a biopsy and there were no tumor cells. With the suspicion of acute fascioliasis (liver stage), due to severe eosinophilia and recent travel to endemic area of Fasciola hepatica, arc II and ELISA Fas 2 we carried out and were positive. Parasitological stool examinations were negative. During hospitalization a hepatic subcapsular hematoma presented as a complication and the patient developed fever because of cholangiolitic microabscesses in the left hepatic lobe. Percutaneous drainage was performed and positive cultures of secretions were obtained She received antibiotic coverage with vancomycin and imipenem. Treatment for Fasciola hepatica was initiated with nitaxozanida but it was discontinued due to oral intolerance. Later, she received a single dose of 250 mg triclabendazole with clinical and laboratory improvement. We presented this case because it is an unusual pseudotumoral presentation in acute hepatic fascioliasis. This parasitic disease is an emerging zoonosis in Perú.

  19. HMGB1 and Extracellular Histones Significantly Contribute to Systemic Inflammation and Multiple Organ Failure in Acute Liver Failure

    Directory of Open Access Journals (Sweden)

    Runkuan Yang

    2017-01-01

    Full Text Available Acute liver failure (ALF is the culmination of severe liver cell injury from a variety of causes. ALF occurs when the extent of hepatocyte death exceeds the hepatic regenerative capacity. ALF has a high mortality that is associated with multiple organ failure (MOF and sepsis; however, the underlying mechanisms are still not clear. Emerging evidence shows that ALF patients/animals have high concentrations of circulating HMGB1, which can contribute to multiple organ injuries and mediate gut bacterial translocation (BT. BT triggers/induces systemic inflammatory responses syndrome (SIRS, which can lead to MOF in ALF. Blockade of HMGB1 significantly decreases BT and improves hepatocyte regeneration in experimental acute fatal liver injury. Therefore, HMGB1 seems to be an important factor that links BT and systemic inflammation in ALF. ALF patients/animals also have high levels of circulating histones, which might be the major mediators of systemic inflammation in patients with ALF. Extracellular histones kill endothelial cells and elicit immunostimulatory effect to induce multiple organ injuries. Neutralization of histones can attenuate acute liver, lung, and brain injuries. In conclusion, HMGB1 and histones play a significant role in inducing systemic inflammation and MOF in ALF.

    Acute liver failure (ALF) is the culmination of severe liver cell injury from a variety of causes. ALF occurs when the extent of hepatocyte death exceeds the hepatic regenerative capacity. ALF has a high mortality that is associated with multiple organ failure (MOF) and sepsis; however, the underlying mechanisms are still not clear. Emerging evidence shows that ALF patients/animals have high concentrations of circulating HMGB1, which can contribute to multiple organ injuries and mediate gut bacterial translocation (BT). BT triggers/induces systemic inflammatory responses syndrome (SIRS), which can lead to MOF in ALF. Blockade of HMGB1 significantly decreases BT and improves hepatocyte regeneration in experimental acute fatal liver injury. Therefore, HMGB1 seems to be an important factor that links BT and systemic inflammation in ALF. ALF patients/animals also have high levels of circulating histones, which might be the major mediators of systemic inflammation in patients with ALF. Extracellular histones kill endothelial cells and elicit immunostimulatory effect to induce multiple organ injuries. Neutralization of histones can attenuate acute liver, lung, and brain injuries. In conclusion, HMGB1 and histones play a significant role in inducing systemic inflammation and MOF in ALF.

  1. Perioperative acute renal failure.

    PURPOSE OF REVIEW: Recent biochemical evidence increasingly implicates inflammatory mechanisms as precipitants of acute renal failure. In this review, we detail some of these pathways together with potential new therapeutic targets. 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.

    The course and outcome of acute viral hepatitis in liver transplanted patients with hepatitis C recurrence are unknown. Here we describe a patient who presented with acute hepatitis B infection while on treatment with peg-interferon and ribavirin for hepatitis C recurrence after liver transplantation. A nucleoside analogue was added (entecavir) and the patient cleared hepatitis C virus (HCV) infection and seroconverted to anti-HBs. In this case, the acute hepatitis B virus (HBV) infection might have contributed to the clearance of HCV, the concomitant immunosuppression might have lead to the slow clearance of HBV infection, and the combined antiviral therapy has helped in the resolution of both infections. Hepatitis B vaccination should be recommended in susceptible patients waiting for liver transplantation.

    To determine the maternal morbidity in pregnant women with acute hepatitis E viral infection. Study Design: Observational, cross-sectional study. Place and Duration of Study: Departments of Obstetrics and Gynaecology and Medicine, Liaquat University of Medical and Health Sciences, Jamshoro, Red Crescent General Hospital and Saint Elizabeth Hospital, Hyderabad, from January 2011 to December 2013. Methodology: The study population was pregnant women with acute hepatitis E infection confirmed by ELIZA technique. Pregnant women with other hepatic viral infections were excluded. All medical and obstetric conditions, and mortality were noted on the predesigned proforma. Results: Out of the total 45 admitted pregnant women with hepatitis E viral infection, 22 women (48.9%) had severe morbidity. The most common were hepatic coma in 8 (36.36%) cases and disseminated intravascular coagulation in 14 (63.63%) cases. Highest mortality rate was seen in women with hepatic coma (100%), while in those with disseminated intravascular coagulation, one out of the 14 cases (7.14%) died. Conclusion: The acute viral hepatitis E infection in pregnant women is associated with maternal morbidities and high mortality rate. (author)

    The relationship between plasma fibronectin, in vitro plasma opsonic activity, which measures the biological activity of fibronectin, and in vivo Kupffer cell function, as assessed by the systemic clearance of microaggregated [ 125 I]albumin, were determined simultaneously in 15 patients with fulminant hepatic failure and 12 normal subjects. Both the plasma fibronectin and plasma opsonic activity were significantly reduced in patients with fulminant hepatic failure, while the systemic clearance of microaggregated albumin was decreased. There was a significant correlation between plasma fibronectin and the plasma opsonic activity on admission, but no correlation could be detected between either parameter and the clearance of microaggregated albumin. A gelatin-derived plasma expander was shown to block the plasma opsonic activity both in vitro and in vivo. The low plasma fibronectin and decreased clearance of microaggregated albumin in fulminant hepatic failure reflect different aspects of the overall impairment of Kupffer cell function

    Reports on colecystic alterations during acute viral hepatitis are more and more frequent; the pathogenesis and clinical meaning of these alterations are still debated. Consensual periportal lymphnode enlargment has been not yet reported. The authors describe four cases of acute viral hepatites in whichUS showed alterations of colecystic walls and/or contents; in two cases enlarged periportal lymphnodes were demonstrated too. Later US exams showed a complete regression of both colecystic and lymphnodal lesions. Clinical findings and laboratory out-comes are evaluated; the connection of US results with hepatitis and its meaning are discussed. The causes of colecystic alterations are still questionable; they might be related to blood disorders or to an increased portal pressure, or else they might be considered as phlogistic lesions. The authors conclude that both colecystic and lymphnodal alterations have a phlogistic nature; moreover, they are not related to a particulary evolution of hepatitis. The importance of distinguishing colecystic alterations from different pathology is stressed.

    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 encephalopathy did not modify CSF-SG (-0.09 %, p = 0.1757). Specific 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

    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. © 2015 Wiley Periodicals, Inc.

    Hepatitis-associated aplastic anemia (HAA) is a rare variant of aplastic anemia in which patients present with severe pancytopenia after an episode of acute hepatitis. The marrow failure is often rapid, severe, and usually fatal if untreated. The preceding hepatitis is largely under-studied. Retrospective study of the clinical and histopathologic features of hepatitis in pediatric patients who subsequently developed aplastic anemia and comparison with consecutive cases of acute liver failure and random cases of autoimmune hepatitis during the same time frame. All 7 patients of HAA had significant elevations in aminotransferases and conjugated hyperbilirubinemia at initial presentation. Echoing liver function indices, cholestatic hepatitis with sinusoidal obstruction-type endothelial injury was seen histomorphologically. Autoimmune hepatitis serology such as anti-F-actin, anti-liver/kidney microsome, and hypergammaglobulinemia was negative in all patients. Five of 7 patients (71.4%) had, however, elevated antinuclear antibody, all with a speckled pattern. Hepatitis virus serology was negative in all patients. By immunohistochemical staining, the lobular CD8/CD4 lymphocyte ratio was markedly elevated in all of the initial samples with significant reduction in this ratio (P = 0.03) in 3 patients post treatment (ursodiol, antibiotics, and/or immunosuppressive therapy). Hepatitis preceding HAA is characterized by marked elevation of aminotransferases, conjugated hyperbilirubinemia, elevated antinuclear antibody with a speckled pattern, cholestatic hepatitis with sinusoidal obstruction morphology, and CD8 dominant lobular infiltrates. The present study suggests HAA may result from cytotoxic T-cell-mediated sinusoidal endothelial and hepatocytic injury.

    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. In-depth analysis of immunological, viral quantification and genotype of acute and fulminant hepatitis A virus. 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. 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 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.

    In developing countries HAV infection is very common in the first years of life and it is often asymptomatic. However especially in regions of intermediate endemicity, exposure to the virus may delay and outbreaks of hepatitis A may be encountered in adults. The aim of this study is to evaluate the clinical and laboratory findings and risk factors of adults with acute viral hepatitis A. In present study we evaluated 203 patient with acute viral hepatitis A, who were admitted to four different hospitals of three cities of Turkey between January 2000-December 2011, retrospectively. The diagnosis of acute viral hepatitis A was performed by laboratory findings and clinically. In a total of 203 patients, 120 (59.1%) patients were male and 83 (40.9%) were female. Mean age of cases with acute viral hepatitis A was 24.7 +11.8 years (ranged 15 to 82 years old). Acute viral hepatitis A were seen in patient who were 15-20 years and 21-30 years old, commonly. Jaundice (74%), fatigue (68%), nausea- vomiting (56%) and dark urine (48%) were the most common symptoms in cases. Prolonged cholestasis (6.8%) was the most common atypical manifestation. Prolonged jaundice was more frequent in the cases with positive HBsAg (P viral hepatitis A can cause atypical presentations such as prolonged cholestasis, acute kidney injury and fulminant hepatitis. Some precautions such as routine vaccination program, improvement of hygiene conditions and informing people about it, should be taken for reducing of acute viral hepatitis A infection incidence.

    Hepatitis E virus (HEV) is a common cause of acute viral hepatitis in developing countries; however, its contribution to acute jaundice syndrome is not well-described. A large outbreak of hepatitis E occurred in northern Uganda from 2007 to 2009. In response to this outbreak, acute jaundice syndrome surveillance was established in 10 district healthcare facilities to determine the proportion of cases attributable to hepatitis E. Of 347 acute jaundice syndrome cases reported, the majority (42%) had hepatitis E followed by hepatitis B (14%), malaria (10%), hepatitis C (5%), and other/unknown (29%). Of hepatitis E cases, 72% occurred in Kaboong district, and 68% of these cases occurred between May and August of 2011. Residence in Kaabong district was independently associated with hepatitis E (adjusted odds ratio = 13; 95% confidence interval = 7-24). The findings from this surveillance show that an outbreak and sporadic transmission of hepatitis E occur in northern Uganda. © The American Society of Tropical Medicine and Hygiene.

    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. Copyright 2006 Wiley-Liss, Inc.

    Acute liver failure (ALF) is a medical emergency requiring immediate evaluation for liver transplantation. We describe an unusual case of a patient who presented with ascites, jaundice, and encephalopathy and was found to have ALF due to natural killer (NK)-like T cell leukemia/lymphoma. The key immunophenotype was CD2+, CD3+, CD7+, CD56+. This diagnosis, which was based on findings in the peripheral blood and ascitic fluid, was confirmed with liver biopsy, and was a contraindication to liver transplantation. A review of the literature shows that hematologic malignancies are an uncommon cause of fulminant hepatic failure, and that NK-like T-cell leukemia/lymphoma is a relatively recently recognized entity which is characteristically CD3+ and CD56+. This case demonstrates that liver biopsy is essential in diagnosing unusual causes of acute liver failure, and that infiltration of the liver with NK-like T-cell lymphoma/leukemia can cause acute liver failure.

    Autoimmune hepatitis (AIH) is characterized by progressive inflammation and necrosis of hepatocytes and eventually leads to a variety of phenotypes, including acute liver dysfunction, chronic progressive liver disease, and fulminant hepatic failure. Although the precise mechanisms of AIH are unknown, environmental factors may trigger disease onset in genetically predisposed individuals. Patients with the recently established entity of AIH with acute presentation often display atypical clinical features that mimic those of acute hepatitis forms even though AIH is categorized as a chronic liver disease. The aim of this study was to identify the precise clinical features of AIH with acute presentation. Eighty-six AIH patients with acute presentation were retrospectively enrolled from facilities across Japan and analyzed for clinical features, histopathological findings, and disease outcomes. Seventy-five patients were female and 11 were male. Patient age ranged from adolescent to over 80 years old, with a median age of 55 years. Median alanine transaminase (ALT) was 776 U/L and median immunoglobulin G (IgG) was 1671 mg/dL. There were no significant differences between genders in terms of ALT (P = 0.27) or IgG (P = 0.51). The number of patients without and with histopathological fibrosis was 29 and 57, respectively. The patients with fibrosis were significantly older than those without (P = 0.015), but no other differences in clinical or histopathological findings were observed. Moreover, antinuclear antibody (ANA)-positive (defined as × 40, N = 63) and -negative (N = 23) patients showed no significant differences in clinical or histopathological findings or disease outcomes. Twenty-five patients experienced disease relapse and two patients died during the study period.

    Hepatitis is common in the Stann Creek District of southern Belize. To determine the etiologies, incidence, and potential risk factors for acute jaundice, we conducted active surveillance for cases. Cases of jaundice diagnosed by a physician within the previous 6 weeks were enrolled. Evaluation included a questionnaire and laboratory tests for hepatitis A, B, C, D, and E, a blood film for malaria, and a serologic test for syphilis. Etiologies of jaundice among 62 evaluable patients included acute hepatitis A, 6 (9.7%), acute hepatitis B, 49 (79.0%), hepatitis non-A-E, 2 (3.2%), and malaria, 5 (8.1%). There were no cases of acute hepatitis E. One patient each with antibody to hepatitis C and D were detected. The annualized incidence of hepatitis A was 0.26 per 1,000. All cases of hepatitis A were in children 4-16 years of age. The annualized incidence of hepatitis B, 2.17 per 1,000, was highest in adults aged 15-44 years (4.4 per 1,000) and was higher in men (36 cases; 3.09 per 1,000) than women (13 cases; 1.19 per 1,000). Four (31%) of the women with hepatitis B were pregnant. The annualized incidence was significantly higher in Mestizo (6.18 per 1000) and Maya (6.79 per 1,000) than Garifuna (0.38 per 1,000) or Creole (0.36 per 1,000). Persons with hepatitis B were significantly more likely to be born outside of Belize (82%), had been in Belize or = 14 years of age with hepatitis B, only 36% were married. Few persons admitted to transfusions, tattoos, IV drug use, multiple sexual partners, visiting prostitutes, or sexually transmitted diseases. Only 1 of 49 had a reactive test for syphilis. Six patients were hospitalized (including 3 with acute hepatitis B and one with hepatitis A), and none to our knowledge died. Acute hepatitis B is the most common cause of viral hepatitis in the Stann Creek District, but the modes of transmission remain obscure. Infants, women attending prenatal clinics, and new workers are potential targets for immunization with hepatitis B

    Full Text Available Breast cancer is the most common cancer in women worldwide. The majority of deaths attributed to breast cancer are a result of metastatic disease, and 30% of early breast cancers (EBC will develop distant disease. The 5-year survival of patients with metastatic disease is estimated at 23%. Breast cancer subtypes continue to be stratified histologically on oestrogen, progesterone and human epidermal growth factor-2 (HER2 receptor expression. HER2-positive breast cancers represent 25% of all breast cancer diagnoses. The therapies available for metastatic breast cancer (MBC are expanding, in particular within the field of HER2-positive disease, with the approval of trastuzumab, pertuzumab, lapatinib and trastuzumab emtansine (TDM-1. Recently, TDM-1 has been shown to improve progression-free survival in HER2 MBC when compared to capecitabine and lapatinib in clinical studies. Its main toxicities are deranged liver function tests and thrombocytopenia. There have also been cases of acute liver failure. Therefore, its use in acute hepatic dysfunction, to our knowledge, has been neither studied nor reported. We report a patient with progressive HER2-positive MBC who had previously responded to multiple HER2-targeted therapies that presented with acute hepatic dysfunction. She was treated with dose-reduced TDM-1 safely, with clear evidence of rapid biochemical, clinical and radiological response. This allowed dose escalation of TDM-1, and the patient maintains an ongoing response.

    Full Text Available Hepatitis B often progresses to decompensated liver cirrhosis requiring orthotopic liver transplantation (OLT. Although newer nucleos(tide analogues result in >90% viral and hepatitis activity control, severely decompensated patients still need OLT because of drug-resistant virus, acute exacerbation, or hepatocellular carcinoma. Acute hepatitis B is also an indication for OLT, because it can progress to fatal acute liver failure. After OLT, the hepatitis B recurrence rate is >80% without prevention, while >90% of transplant recipients are clinically controlled with combined hepatitis B immunoglobulin (HBIG and nucleos(tide analogue treatment. However, long-term HBIG administration is associated with several unresolved issues, including limited availability and extremely high cost; therefore, several treatment protocols with low-dose HBIG, combined with nucleos(tide analogues, have been investigated. Another approach is to induce self-producing anti-hepatitis B virus (HBV antibodies using an HBV envelope (HBs antigen vaccine. Patients who are not HBV carriers, such as those with acutely infected liver failure, are good candidates for vaccination. For chronic HBV carrier liver cirrhosis patients, a successful vaccine response can only be achieved in selected patients, such as those treated with experimentally reduced immunosuppression protocols. The present protocol for post-OLT HBV control and the future prospects of newer treatment strategies are reviewed.

    Herpes simplex virus (HSV) hepatitis is a rare cause of acute liver failure (ALF). It carries a mortality rate of 80% if untreated, thus early identification and treatment are critical. Without high clinical suspicion, HSV hepatitis is difficult to diagnose. A 48-year-old Hispanic female presented with a 4-day history of abdominal pain and a vaginal cuff tear requiring laparoscopic repair. She subsequently developed postsurgical disseminated HSV, resulting in ALF. Acyclovir was initiated, but she was resistant to treatment. She was given additional foscarnet and responded without requiring a liver transplant.

    Hepatitis E is caused by infection with the hepatitis E virus (HEV). HEV is transmitted orally via HEV-contaminated food or drink. Hepatitis E usually shows mild symptoms and is self-limiting in the general population; however, it may progress to chronic hepatitis in immunosuppressed patients such as recipients of organ transplantation. However, a few cases of acute hepatitis E have been reported in organ transplantation recipients. We herein report a case of acute hepatitis E in a 31-year-old male renal transplant recipient. The patient underwent renal transplantation 2 years ago, and his postoperative course was uneventful without rejection. After complaining of general fatigue and low-grade fever for 1 week, he was referred to and admitted to our hospital. Careful interview revealed that he ate undercooked pork 10 weeks prior. Blood analysis revealed liver dysfunction but was serologically negative for hepatitis A, B and C virus, cytomegalovirus infection and collagen diseases. Immunoglobulin A antibody against hepatitis E virus (HEV-IgA) was also negative at that point. After 2 weeks of admission, HEV-IgA and HEV-RNA were measured again as hepatitis E could not be ruled out due to history of ingestion of undercooked meat that may have been contaminated with HEV. At that time, HEV-IgA and HEV-RNA (genotype 3) were positive. Thus, an acute hepatitis E was diagnosed. His liver function gradually improved to within the normal range, and HEV-IgA and HEV-RNA were negative at 11 weeks after admission. In conclusion, we describe here a case of acute hepatitis E in a renal transplant recipient. Careful interview regarding the possibility of ingestion of HEV-contaminated food and repeated measurements of HEV-IgA were helpful in finalizing a diagnosis.

  8. Serum 1H-NMR metabolomic fingerprints of acute-on-chronic liver failure in intensive care unit patients with alcoholic cirrhosis.

    Roland Amathieu

    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.

    Liver failure represents a major therapeutic challenge, and yet basic pathophysiological questions about hepatic perfusion and oxygenation in this condition have been poorly investigated. In this study, hepatic blood flow (HBF) and splanchnic oxygen delivery (DO2, sp) and oxygen consumption (VO2,sp) were assessed in patients with liver failure defined as hepatic encephalopathy grade II or more. Measurements were repeated after high-volume plasmapheresis (HVP) with exchange of 8 to 10 L of plasma. HBF was estimated by use of constant infusion of D-sorbitol and calculated according to Fick's principle from peripheral artery and hepatic vein concentrations. In 14 patients with acute liver failure (ALF), HBF (1.78 +/- 0.78 L/min) and VO2,sp (3.9 +/- 0.9 mmol/min) were higher than in 11 patients without liver disease (1.07 +/- 0.19 L/min, P HVP, HBF increased from 1.67 +/- 0.72 to 2.07 +/- 1.11 L/min (n=11) in ALF, and from 1.89 +/- 1.32 to 2.34 +/- 1.54 L/min (n=7) in AOCLD, P HVP. Blood flow was redirected to the liver as the systemic vascular resistance index increased (1,587 +/- 650 vs. 2, 020 +/- 806 Dyne. s. cm-5. m2, P HVP, but as cardiac output increased from 9.1 +/- 2.8 to 10.1 +/- 2.9 L/min (P HVP (n=18), DO2,sp increased by 15% (P HVP. Changes of ET-1 were positively correlated with changes in HBF (P HVP (P HVP did not correlate. Our data suggest that liver failure is associated with increased HBF and VO2, sp. HVP further increased HBF and DO2,sp but VO2,sp was unchanged, indicating that splanchnic hypoxia was not present.

    Full Text Available ObjectiveTo 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. MethodsThe 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 multivariate (Cox’s test regression analyses. The association of risk factors with patient survival was assessed by Kaplan-Meier curve analysis. ResultsThe 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 encephalopathy, presence of hepatorenal syndrome, PTA

  15. Risk factors for acute renal failure: inherent and modifiable risks.

    Our purpose is to discuss established risk factors in the development of acute renal failure and briefly overview clinical markers and preventive measures. Findings from the literature support the role of older age, diabetes, underlying renal insufficiency, and heart failure as predisposing factors for acute renal failure. Diabetics with baseline renal insufficiency represent the highest risk subgroup. An association between sepsis, hypovolemia, and acute renal failure is clear. Liver failure, rhabdomyolysis, and open-heart surgery (especially valve replacement) are clinical conditions potentially leading to acute renal failure. Increasing evidence shows that intraabdominal hypertension may contribute to the development of acute renal failure. Radiocontrast and antimicrobial agents are the most common causes of nephrotoxic acute renal failure. In terms of prevention, avoiding nephrotoxins when possible is certainly desirable; fluid therapy is an effective prevention measure in certain clinical circumstances. Supporting cardiac output, mean arterial pressure, and renal perfusion pressure are indicated to reduce the risk for acute renal failure. Nonionic, isoosmolar intravenous contrast should be used in high-risk patients. Although urine output and serum creatinine lack sensitivity and specificity in acute renal failure, they remain the most used parameters in clinical practice. There are identified risk factors of acute renal failure. Because acute renal failure is associated with a worsening outcome, particularly if occurring in critical illness and if severe enough to require renal replacement therapy, preventive measures should be part of appropriate management.

    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.

    Congestive hepatopathy (CH) and acute liver failure (ALF) are common among biventricular heart failure patients. We sought to evaluate the impact of total artificial heart (TAH) therapy on hepatic function and associated clinical outcomes. A total of 31 patients received a Syncardia Total Artificial Heart. Preoperatively 17 patients exhibited normal liver function or mild hepatic derangements that were clinically insignificant and did not qualify as acute or chronic liver failure, 5 patients exhibited ALF and 9 various hepatic derangements owing to CH. Liver associated mortality and postoperative course of liver values were prospectively documented and retrospectively analyzed. Liver associated mortality in normal liver function, ALF and CH cases was 0%, 20% (P=0.03) and 44.4% (P=0.0008) respectively. 1/17 (5.8%) patients with a normal liver function developed an ALF, 4/5 (80%) patients with an ALF experienced a markedly improvement of hepatic function and 6/9 (66.6%) patients with CH a significant deterioration. TAH therapy results in recovery of hepatic function in ALF cases. Patients with CH prior to surgery form a high risk group with increased liver associated mortality.

    Hepatitis E virus (HEV) is a common cause of acute viral hepatitis in developing countries; however, its contribution to acute jaundice syndrome is not well-described. A large outbreak of hepatitis E occurred in northern Uganda from 2007 to 2009. In response to this outbreak, acute jaundice syndrome surveillance was established in 10 district healthcare facilities to determine the proportion of cases attributable to hepatitis E. Of 347 acute jaundice syndrome cases reported, the majority (42%) had hepatitis E followed by hepatitis B (14%), malaria (10%), hepatitis C (5%), and other/unknown (29%). Of hepatitis E cases, 72% occurred in Kaboong district, and 68% of these cases occurred between May and August of 2011. Residence in Kaabong district was independently associated with hepatitis E (adjusted odds ratio = 13; 95% confidence interval = 7–24). The findings from this surveillance show that an outbreak and sporadic transmission of hepatitis E occur in northern Uganda. PMID:25448237

    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

    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.

    Hepatitis-E is an enterically transmitted virus causing acute hepatitis. Mostly it is a self-limiting clinical course, but can be life threatening in certain high risk groups. Pakistan is endemic for Hepatitis-E with limited published literature. The aim of this study is to evaluate the predictors of mortality in patients with acute Hepatitis-E. Methods: We analyzed the medical records of 369 adult patients with Hepatitis-E infection admitted at Aga khan University Hospital, from January 1996 to December 2010. Details of their laboratory investigations, clinical course and complications such as FHF and mortality were noted. The outcome was compared, and determinants of mortality were evaluated in important patient subgroups. Results: Out of 369 patients with Hepatitis-E, 326 (88.3%) were discharged after full recovery. Out of these 22 (6%) patients had chronic liver disease CLD in this study, of whom 10 (2.7%) expired (p-value <0.001). There were about 67 (18%) pregnant patients, with a mean gestational age of 29.19 ± 7.68 weeks and 5 (1.4%) pregnant patients died (p-value=0.23). A total of 58 (15.7%) patients were co-infected with other hepatotropic virus, and a comparison did not find an increased risk of mortality in this group. Conclusion: This study showed that Hepatitis-E is significantly associated with mortality in patients suffering from pre-existing chronic liver disease. Pregnancy was not a determinant of mortality in Hepatitis-E patients in this study, and neither was co-infection with other Hepatotropic viruses. (author)

    Full Text Available Xiao-chai-hu-tang (syo-saiko-to in Japanese is a herbal remedy that has been widely used in China for treatment of respiratory, hepatobiliary, and gastrointestinal diseases, particularly among patients with chronic liver disease. However, its safety has recently been challenged. We, herein, report a Chinese patient with acute hepatitis induced by this herb. A 52-year-old woman presented with weakness, fatigue, and tea-colored urine after continual consumption of the decoction of xiao-chai-hu-tang for 1.5 months. Laboratory studies disclosed acute hepatitis even though all of the viral hepatitis markers were negative. Liver biopsy also revealed a picture of acute hepatocellular hepatitis. The symptoms improved after discontinuing the drug, and liver biochemical tests normalized 2 months later. The case report reminds us of the probable adverse drug reaction of herbs, even in some that are claimed to have hepatoprotective effects.

    Full Text Available Aim: This study was performed to evaluate the diagnostic value of hepatocyte-derived microRNA (miRNA-122 in acute and chronic hepatitis of dogs. Materials and Methods: A total of 26 dogs presented at Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Cairo University, 16 dogs out of 26 showing clinical signs of hepatic insufficiency were subjected to clinical, ultrasonographic, hematobiochemical and ultrasound-guided fine-needle biopsy for cytological and histopathological investigations. On the basis of these results, 7 dogs out of 16 dogs were found to be suffering from acute hepatitis and 9 dogs suffering from chronic hepatitis. 10 clinically healthy dogs were kept as control. Serum hepatocyte-derived miRNA-122 was analyzed by real-time quantitative polymerase chain reaction in all dogs. Results: The dogs suffering from acute hepatitis manifested jaundice, vomiting, and depression while dogs with chronic hepatitis manifested anorexia, abdominal distension, weight loss, and melena. Hematological parameters showed normocytic normochromic anemia and thrombocytopenia in both acute and chronic hepatitis groups. Alanine aminotransferase (ALT, aspartate aminotransferase (AST, alkaline phosphatase (ALP, and total bilirubin were significantly higher than control values in acute hepatitis. In chronic hepatitis, total protein and albumin were significantly lower than control values with normal ALT, AST, ALP, and gamma-glutamyltransferase values. Ultrasonography revealed a diffuse decrease in hepatic echogenicity in acute hepatitis while the increase in hepatic echogenicity and anechoic ascetic fluid in chronic hepatitis. Cytology revealed hepatic vacuolar degeneration and histopathology revealed necrosis and apoptosis of hepatocyte in acute hepatitis while revealed massive fibrous tissue proliferation in hepatic parenchyma in chronic hepatitis.

    A group of 24 patients with acute viral hepatitis B was assessed for specific antibodies against the ''core'' antigen class IgM (HB c AB IgM) during 1st-4th week of the illness. These specific antibodies were positive in all patients, the mean titre being 10 -5 . The high content of these antibodies persisted for 1-2 months after the onset of the disease. The assessment of specific antibodies against ''core'' antigen class IgM was also made in a group of 39 patients with chronic hepatitis. In these patients positive HB c Ab IgM with a lower content were found (titre 10 -3 ) than in the group with acute viral hepatitis B. Based on the results the conclusion is made that specific antibodies HB c Ab class IgM are, in addition to the estimation of the surface antigen of the hepatitis B virus (HB s Ag), one more indicator of acute viral hepatitis B. The assessment is diagnostically valuable, in particular in acute hepatitis of obscure etiology, in acute jaundice of obscure etiology for the period of low and short-term antigenemia.

    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 Acute cholecystitis is an inflammation of the gallbladder wall, usually caused by gallstones in the cystic duct, which causes attacks of severe pain. At least 95% of the population with acute inflammation of the gallbladder have gallstones. Acute viral hepatitis is the liver inflammation accompanied by nausea, faintness, vomiting, pain below the right rib arch, jaundice. The presence of acute cholecystitis intensifies the existing symptoms. The aim of the paper was to show the incidence of the gallbladder inflammation in patients with acute hepatitis A or B. This retrospective-prospective study involved 110 patients treated for viral hepatitis A or B and had severe abdominal pain during hospitalization. The selected sample involved more male examinees - 63 (62% compared to female ones - 47 (38%. The most frequent age of examinees was 30-50 years, 82 (83%, and cholecystitis during hepatitis was also most common in the age group 30-50 years, 28 (73% patients. Cholecystitis was more common in patients with acute hepatitis B - 21 (55% examinees than in patients with acute hepatitis A - 17 (45% examinees. Ultrasound examination, performed in 24 (63% examinees showed gallstones in inflamed gallbladder, while 14 (37% examinees had the inflammation of the gallbladder without gallstones. The most common cause of severe abdominal pain in patients with acute liver infection caused by HAV and HBV infection was the gallbladder, 38 (34.5% patients. Cholecystitis was more common in patients with acute hepatitis B, 21 (55% examinees, than in those with an acute hepatitis A, 17 (45% examinees.

    Malaria has protean clinical manifestations and renal complications, particularly acute renal failure that could be life threatening. To evaluate the incidence, clinical profile, ou 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 coagulation, and high serum creatinine were the main predictors of mortality. We conclude that malaria is associated with acute renal failure, which occurs most commonly in plasmodium falciparum infected patients. Early diagnosis and prompt dialysis with supportive management can reduce morality and enhance recovery of renal function (Author).

    Not responsible self-medication refers to drug use in high doses without rational indication and often associated with alcohol abuse. It can lead to liver damage and drug interactions, and may cause liver failure. To warn about how the practice of self-medication can be responsible for acute liver failure. Were used the Medline via PubMed, Cochrane Library, SciELO and Lilacs, and additional information on institutional sites of interest crossing the headings acute liver failure [tiab] AND acetaminophen [tiab]; self-medication [tiab] AND acetaminophen [tiab]; acute liver failure [tiab] AND dietary supplements [tiab]; self-medication [tiab] AND liver failure [tiab] and self-medication [tiab] AND green tea [tiab]. In Lilacs and SciELO used the descriptor self medication in Portuguese and Spanish. From total surveyed were selected 27 articles and five sites specifically related to the purpose of this review. Legislation and supervision disabled and information inaccessible to people, favors the emergence of cases of liver failure drug in many countries. In the list of released drugs that deserve more attention and care, are some herbal medicines used for the purpose of weight loss, and acetaminophen. It is recommended that institutes of health intensify supervision and better orient their populations on drug seemingly harmless, limiting the sale of products or requiring a prescription for release them.

    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.

    A group of 24 patients with acute viral hepatitis B was assessed for specific antibodies against the ''core'' antigen class IgM (HB/sub c/AB IgM) during 1st-4th week of the illness. These specific antibodies were positive in all patients, the mean titre being 10/sup -5/. The high content of these antibodies persisted for 1-2 months after the onset of the disease. The assessment of specific antibodies against ''core'' antigen class IgM was also made in a group of 39 patients with chronic hepatitis. In these patients positive HB/sub c/Ab IgM with a lower content were found (titre 10/sup -3/) than in the group with acute viral hepatitis B. Based on the results the conclusion is made that specific antibodies HB/sub c/Ab class IgM are, in addition to the estimation of the surface antigen of the hepatitis B virus (HB/sub s/Ag), one more indicator of acute viral hepatitis B. The assessment is diagnostically valuable, in particular in acute hepatitis of obscure etiology, in acute jaundice of obscure etiology for the period of low and short-term antigenemia.

    Full Text Available La hepatitis isquémica es una complicación sumamente infrecuente de cirugía cardiovascular. Las biopsias muestran necrosis centrolobulillar. El término de "hepatitis" fue propuesto debido al aumento de transaminasas similar a aquellas de origen infeccioso, e "isquémica" por falla en la perfusión hepática. Posteriormente se definió el término de hepatitis isquémica como cuadro de elevación aguda y reversible (dentro de las 72 horas de transaminasas de hasta 20 veces el valor normal, asociado a trastornos en la perfusión hepática, luego de haber excluido otras causas de hepatitis aguda o daño hepatocelular.

    Infective endocarditis is one of the most common infections among intravenous drug addicts. Its complications can affect many systems, and these can include acute renal failure. There is a scarcity of cases in the literature related to acute renal failure secondary to infective endocarditis treated with peritoneal dialysis. In this paper, the case of a 48-year-old Saudi male is reported, who presented with features suggestive of infective endocarditis and who developed acute kidney injury that was treated successfully with high tidal volume automated peritoneal dialysis. To our knowledge, this is the second report of such an association in the literature. A 48-year-old Saudi gentleman diagnosed to have a glucose-6-phosphate dehydrogenase deficiency and hepatitis C infection for the last 9 years, presented to the emergency department with a history of fever of 2 days' duration. On examination: his temperature = 41 °C, there was clubbing of the fingers bilaterally and a pansystolic murmur in the left parasternal area. The results of the blood cultures and echocardiogram were supportive of the diagnosis of infective endocarditis, and the patient subsequently developed acute kidney injury, and his creatinine reached 5.2 mg/dl, a level for which dialysis is essential for the patient to survive. High tidal volume automated peritoneal dialysis is highly effective as a renal replacement therapy in acute renal failure secondary to infective endocarditis if no contraindication is present.

    Mongolia has one of the highest hepatitis A, C, B and D infection incidences worldwide. We sought to investigate changes in the proportion of acute viral hepatitis types in Mongolia over the last decade. The cohort comprised 546 consecutive patients clinically diagnosed with acute viral hepatitis from January 2012 to December 2014 in Ulaanbaatar Hospital, Mongolia. A time trend analysis investigating the change in proportion of acute hepatitis A virus, hepatitis C virus (HCV), hepatitis B virus (HBV) and hepatitis delta virus (HDV) infection among the cohort with respect to a previous published study was undertaken. Acute hepatitis A, B and C was diagnosed in 50.9%, 26.2% and 6.0% of the cohort. Notably, 16.8% of the cohort had a dual infection. The etiologies of acute viral hepatitis were varied by age groups. The most common cause of acute viral hepatitis among 2-19 year olds was hepatitis A, HBV and superinfection with HDV among 20-40 year olds, and HCV among 40-49 year olds. Patients with more than one hepatitis virus infection were significantly older, more likely to be male and had a higher prevalence of all risk factors for disease acquisition. These patients also had more severe liver disease at presentation compared to those with mono-infection. Acute viral hepatitis is still prevalent in Mongolia. Thus, the need for proper infection control is increasing in this country.

    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.

    Full Text Available Hepatic encephalopathy is potentially reversible, or progressive neuropsychiatric syndrome characterized by changes in cognitive function, behavior and personality changes, and transient neurologic symptoms and characteristic electroencephalographic patterns associated with acute and chronic liver failure. For some time, there has been controversy regarding the origin of toxins responsible for the change of mental state. It was found that the occurrence of hepatic encephalopathy is responsible for multiple organ peripheral changes (intestinal changes, abnormalities of portal-systemic circulation, liver failure, loss of muscle tissue, changes in brain intracellular communication (osmotic changes, astrocytes and axonal abnormalities in communication, changes in cerebral perfusion and ammonia, endogenous benzodiazepines, gamma amino butyric acid, derivatives of methionine and false neurotransmitters. The aforementioned metabolic factors that contribute to the development of hepatic encephalopathy are not mutually exclusive and multiple factors may be present at the same time.

    Congestion is the most frequent cause for hospitalization in acute decompensated heart failure. Although decongestion is a major goal of acute therapy, it is unclear how the clinical components of congestion (eg, peripheral edema, orthopnea) contribute to outcomes after discharge or how well decongestion is maintained. A post hoc analysis was performed of 496 patients enrolled in the Diuretic Optimization Strategy Evaluation in Acute Decompensated Heart Failure (DOSE-AHF) and Cardiorenal Rescue Study in Acute Decompensated Heart Failure (CARRESS-HF) trials during hospitalization with acute decompensated heart failure and clinical congestion. A simple orthodema congestion score was generated based on symptoms of orthopnea (≥2 pillows=2 points, fails to relieve orthodema during hospitalization or to prevent recurrence after discharge.

    To identify current risk factors for hepatitis C virus (HCV) acquisition among Egyptians. Patients with acute HCV were identified through a surveillance system of acute hepatitis in four fever hospitals in Egypt between 2002 and 2012. Case-control analysis was conducted, cases being incident acute symptomatic HCV and controls being acute hepatitis A identified at the same hospitals. The questionnaire covered iatrogenic, community and household exposures to HCV in the 1-6 months prior to onset of symptoms. Multivariate models were built to identify risk factors associated with HCV acquisition among non-drug users and drug users separately. Among non-drug users, hospital admission was independently associated with acute HCV infection (OR = 4.2, 95% CI = 1.7-10.5). Several iatrogenic procedures, for example admission in a surgery unit, sutures, IV injections and IV infusions, highly correlated with hospital admission, were also associated with acute HCV infection and could have been used in the final model instead of hospital admission. Among drug users, identified risk factors were multiple sexual relations (OR = 4.0, 95% CI = 1.1-14.7), intravenous drug use (OR = 3.9, 95% CI = 1.2-13.0) and shaving at the barbershops (OR = 8.7, 95% CI = 2.4-31.4). Illiteracy and marriage were significant risk factors in both groups. Invasive medical procedures are still a major risk for acquiring new HCV infections in Egypt, as is illicit drug use in spreading HCV infection. © 2014 John Wiley & Sons Ltd.

  14. Fluid removal in acute heart failure: diuretics versus devices.

    Science.gov (United States)

    Krishnamoorthy, Arun; Felker, G Michael

    2014-10-01

    Fluid removal and relief of congestion are central to treatment of acute heart failure. Diuretics have been the decongestive mainstay but their known limitations have led to the exploration of alternative strategies. This review compares diuretics with ultrafiltration and examines the recent evidence evaluating their use. Relevant recent studies are the Diuretic Optimization Strategies Evaluation trial (of diuretics) and the Cardiorenal Rescue Study in Acute Decompensated Heart Failure (of ultrafiltration). The Diuretic Optimization Strategies Evaluation study evaluated strategies of loop diuretic use during acute heart failure (continuous infusion versus intermittent bolus and high dose versus low dose). After 72  h, there was no significant difference with either comparison for the coprimary end points. Patients treated with a high-dose strategy tended to have greater diuresis and more decongestion compared with low-dose therapy, at the cost of transient changes in renal function. The Cardiorenal Rescue Study in Acute Decompensated Heart Failure study showed that in acute heart failure patients with persistent congestion and worsening renal function, ultrafiltration, as compared with a medical therapy, was associated with similar weight loss but greater increase in serum creatinine and more adverse events. Decongestion remains a major challenge in acute heart failure. Although recent studies provide useful data to guide practice, the relatively poor outcomes point to the continued need to identify better strategies for safe and effective decongestion.

    Sixteen infants, 2 to 35 days of age, had acute renal failure, a diagnosis based on serum creatinine concentrations greater than 1.5 mg/dL for at least 24 hours. Eight infants were oliguric (urine flow less than 1.0 mL/kg/h) whereas the remainder were nonoliguric. To determine clinical parameters useful in prognosis, urine flow rate, duration of anuria, peak serum creatinine, urea (BUN) concentration, and nuclide uptake by scintigraphy were correlated with recovery. Nine infants had acute renal failure secondary to perinatal asphyxia, three had acute renal failure as a result of congenital cardiovascular disease, and four had major renal anomalies. Four oliguric patients died: three of renal failure and one of heart failure. All nonoliguric infants survived with mean follow-up serum creatinine concentration of 0.8 +/- 0.5 (SD) mg/dL whereas that of oliguric survivors was 0.6 +/- 0.3 mg/dL. Peak serum creatinine concentration did not differ between those patients who were dying and those recovering. All infants who were dying remained anuric at least four days and revealed no renal uptake of nuclide. Eleven survivors were anuric three days or less, and renal perfusion was detectable by scintigraphy in each case. However, the remaining survivor (with bilateral renal vein thrombosis) recovered after 15 days of anuria despite nonvisualization of kidneys by scintigraphy. In neonates with ischemic acute renal failure, lack of oliguria and the presence of identifiable renal uptake of nuclide suggest a favorable prognosis

    Sixteen infants, 2 to 35 days of age, had acute renal failure, a diagnosis based on serum creatinine concentrations greater than 1.5 mg/dL for at least 24 hours. Eight infants were oliguric (urine flow less than 1.0 mL/kg/h) whereas the remainder were nonoliguric. To determine clinical parameters useful in prognosis, urine flow rate, duration of anuria, peak serum creatinine, urea (BUN) concentration, and nuclide uptake by scintigraphy were correlated with recovery. Nine infants had acute renal failure secondary to perinatal asphyxia, three had acute renal failure as a result of congenital cardiovascular disease, and four had major renal anomalies.

    Acute hepatic encephalopathy has significant morbidity and mortality in liver transplant recipients unless it is promptly treated. We evaluated the brain magnetic resonance (MR) imaging findings associated with acute hepatic encephalopathy in transplant recipients. We retrospectively reviewed the clinical and imaging data and outcomes of twenty-five liver transplant patients (16 male; mean age, 49.3 years) with clinically diagnosed acute hepatic encephalopathy and forty liver transplant patients (20 males; mean age, 45.5 years) without neurological symptoms suggestive of hepatic encephalopathy at our institution. Bilateral symmetric hyperintensities of the insular cortex and cingulate gyrus were observed in twenty-one patients (84.00%), bilateral symmetric extensive increased cortical signal intensity (involving two or more regions) was observed in 72.00% of the patients, leptomeningeal enhancement in 73.68%, and visualization of prominent venules in 52.00%. The most common symptom at diagnosis was rigidity (n = 14), and the plasma ammonia levels ranged from 68.63 to 192.16 μmol/L. After active treatment, 17 patients gradually recovered, four patients suffered from mild or moderate neurologic deficits, and four patients with widespread brain edema died. The specific brain MR imaging features were bilateral symmetric increased cortical signal intensity, especially in the insular cortex and cingulate gyrus, leptomeningeal enhancement, visualization of the prominent venules, and widespread brain edema. These features may indicate poor prognosis and should alert radiologists to the possibility of acute hepatic encephalopathy in liver transplant recipients and encourage clinicians to prepare appropriate treatment in advance.

    Infection with hepatitis viruses can lead to acute hepatitis with the risk of developing liver failure. Chronic viral hepatitis may evolve into liver cirrhosis and hepatocellular carcinoma. Thus, prevention of viral hepatitis and its sequels is essential. Vaccination against hepatitis A is successful in almost all individuals. Protective antibodies maintain for at least 20 years. Booster vaccinations are not necessary. Since the introduction of hepatitis A vaccines, the incidence of new HAV-infections has declined significantly. Hepatitis B vaccines are safe and highly effective. Special populations such as dialysis patients or immunocompromised patients require special vaccine schedules. New vaccines with improved adjuvants are currently being tested in clinical trials. So far there is no hepatitis C vaccine on the horizon. Prophylaxis of HCV-infections relies primarily on hygiene measures. Early therapy of acute hepatitis C can prevent chronic hepatitis C. HDV-infection can only be established if HBsAg is present. Thus, prevention of hepatitis B or elimination of HBsAg means prevention of hepatitis delta. Hepatitis E vaccines have been evaluated in phase III studies. The development of HEV vaccines becomes more relevant since chronic HEV infections have been reported in immunosuppressed individuals.

    Full Text Available 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.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.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.sTNFR:IgG-Fc improved survival rate during development of ACLF via ameliorating liver injury with a potential therapeutic value.

    Whether or not the definition of a worsening renal function (WRF) is adequate for the evaluation of acute renal failure in patients with acute heart failure is unclear. One thousand and eighty-three patients with acute heart failure were analysed. A WRF, indicated by a change in serum creatinine ≥0.3 mg/mL during the first 5 days, occurred in 360 patients while no-WRF, indicated by a change failure; n = 98). The patients were assigned to another set of four groups: no-WRF/no-AKI (n = 512), no-WRF/AKI (n = 211), WRF/no-AKI (n = 239), and WRF/AKI (n = 121). A multivariate logistic regression model found that no-WRF/AKI and WRF/AKI were independently associated with 365 day mortality (hazard ratio: 1.916; 95% confidence interval: 1.234-2.974 and hazard ratio: 3.622; 95% confidence interval: 2.332-5.624). Kaplan-Meier survival curves showed that the rate of any-cause death during 1 year was significantly poorer in the no-WRF/AKI and WRF/AKI groups than in the WRF/no-AKI and no-WRF/no-AKI groups and in Class I and Class F than in Class R and the no-AKI group. The presence of AKI on admission, especially Class I and Class F status, is associated with a poor prognosis despite the lack of a WRF within the first 5 days. The prognostic ability of AKI on admission may be superior to WRF within the first 5 days. © 2018 The Authors.

    Acute hepatitis A is a fecal-oral transmitted disease related to inadequate sanitary conditions. In addition to its traditional classification, several outbreaks in the men who have sex with men (MSM) population have resulted in acute hepatitis A being recognized as a sexually transmitted disease. However, few studies have clarified the clinical manifestations in these outbreaks involving the MSM population. Beginning in June 2015, there was an outbreak of acute hepatitis A involving the MSM population in Northern Taiwan. We conducted a 15-year retrospective study by recruiting 207 patients with the diagnosis of acute hepatitis A that included the pre-outbreak (January 2001 to May 2015) and outbreak (June 2015 to August 2016) periods in a tertiary medical center in Northern Taiwan. Using risk factors, comorbidities, presenting symptoms, laboratory test results and imaging data, we aimed to evaluate the clinical significance of acute hepatitis A in the MSM population, where human immunodeficiency virus (HIV) coinfection is common. There was a higher prevalence of reported MSM (p hepatitis A during the outbreak period. The outbreak population had more prominent systemic symptoms, was more icteric with a higher total bilirubin level (p hepatitis A relapse. The clinical course of acute hepatitis A during an outbreak involving the MSM and HIV-positive population is more symptomatic and protracted than in the general population.

This study is aimed to reveal the cell differentiation environment and the significance of Treg and Th17 balance in the development of acute and chronic HBV infection. Methods Ten patients with acute HBV infection (AHB and forty-eight patients with chronic HBV infection, including 12 asymptomatic HBV carriers (HBV carriers, 18 chronic hepatitis B patients (CHB and 18 acute-on-chronic HBV-related liver failure (ACHBLF were enrolled. Treg and Th17 cells differentiation related cytokine levels were detected by using ELISA. Flow cytometry was employed to count the Treg and Th17 frequency in peripheral blood. Results Compared to health controls both AHB and ACHBLF patients favoured Th17 cell differentiation, accompanied by a higher proportion of peripheral Th17 cells (P  Conclusions Th17 cells are involved in acute and chronic HBV infection, especially in AHB and ACHBLF. CHB and ACHBLF patients manifested obvious Treg/Th17 ratio imbalance, which might be linked to disease progression and the continuous HBV infection.

    There are few data on the role of liver dysfunction in patients with end-stage heart failure supported by mechanical circulatory support. The aim of our study was to investigate predictors for acute liver failure in patients with end-stage heart failure undergoing mechanical circulatory support. A consecutive 164 patients with heart failure with New York Heart Association class IV undergoing mechanical circulatory support were investigated for acute liver failure using the King's College criteria. Clinical characteristics of heart failure together with hemodynamic and laboratory values were analyzed by logistic regression. A total of 45 patients (27.4%) with heart failure developed subsequent acute liver failure with a hospital mortality of 88.9%. Duration of heart failure, cause, cardiopulmonary resuscitation, use of vasopressors, central venous pressure, pulmonary capillary wedge pressure, pulmonary pulsatility index, cardiac index, and transaminases were not significantly associated with acute liver failure. Repeated decompensation, atrial fibrillation (P failure in univariate analysis only. In multivariable analysis, decreased antithrombin III was the strongest single measurement indicating acute liver failure (relative risk per %, 0.84; 95% confidence interval, 0.77-0.93; P = .001) and remained an independent predictor when adjustment for the Model for End-Stage Liver Disease score was performed (relative risk per %, 0.89; 95% confidence interval, 0.80-0.99; P = .031). Antithrombin III less than 59.5% was identified as a cutoff value to predict acute liver failure with a corresponding sensitivity of 81% and specificity of 87%. In addition to the Model for End-Stage Liver Disease score, decreased antithrombin III activity tends to be superior in predicting acute liver failure compared with traditionally thought predictors. Antithrombin III measurement may help to identify patients more precisely who are developing acute liver failure during mechanical

    This study assessed the safety and initial efficacy of umbilical cord-derived mesenchymal stem cell (UC-MSC) transfusions for acute-on-chronic liver failure (ACLF) patients associated with hepatitis B virus (HBV) infection. No significant side effects were observed, and the UC-MSC transfusions significantly increased the survival rates in ACLF patients. It was found that UC-MSC transfusions are safe in the clinic and may serve as a novel therapeutic approach for HBV-associated ACLF patients.

    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

    In January 2012, Mongolia started a hepatitis A vaccination program, which has not yet been evaluated. The first occurrence of autochthonous acute hepatitis E in 2013, caused by genotype 4 hepatitis E virus (HEV), suggests the need for a routine study to monitor its prevalence. One hundred fifty-four consecutive patients who were clinically diagnosed with acute hepatitis between 2014 and 2015 in Ulaanbaatar, Mongolia were studied. By serological and molecular testing followed by sequencing and phylogenetic analysis, only one patient (0.6%) was diagnosed with acute hepatitis A, caused by genotype IA hepatitis A virus (HAV), and 32 (20.8%) patients were diagnosed with acute hepatitis E, caused by genotype 1 HEV. The 32 HEV isolates obtained in this study shared 99.5-100% nucleotide identity and were grouped into a cluster separated from those of subtypes 1a to 1f. Upon comparison of p-distances over the entire genome, the distances between one representative HEV isolate (MNE15-072) and 1a-1f strains were 0.071-0.137, while those between 1b and 1c were 0.062-0.070. In conclusion, the prevalence of acute hepatitis A has decreased in Mongolia since the start of the vaccination program, while the monophyletic genotype 1 HEV strain of a probably novel subtype has been prevalent. © 2017 Wiley Periodicals, Inc.

    Full Text Available Herbal remedies have become increasingly popular throughout the globe as a result of disappointment with conventional medicines. The public often regards them as harmless. However, some of these products or their metabolites can cause adverse effects such as liver damage. In this study, two patients who developed acute hepatitis due to consuming herbal tea are presented. Twenty-six and thirty-year-old two women were admitted to our department with symptoms of nausea, vomiting, anorexia and weakness. Serum alanine aminotransferase and aspartate aminotransferase levels were increased; all serological tests for viral hepatitis and autoimmune disorders were negative. They had consumed an herbal tea containing fennel and cumin to increase lactation everyday for three-four weeks. Discontinuation of the herbal tea resulted in normalization of liver enzymes four-five weeks later. To the best of our knowledge, this is the first report of hepatitis possibly related to use of an herbal tea containing fennel and cumin. This study suggests that herbal tea containing fennel and cumin can cause hepatotoxicity, which could be clinically confused with other causes of acute hepatitis. Clinicians may face with a case of acute hepatitis that is not readily diagnosed, and should question patients about herbal remedy use.

    Acquired aplastic anemia(aAA is a severe and rare disease, characterized by hematopoietic bone marrow failure and peripheral cytopenia. The pathophysiology is immune mediated in most cases, activated T1 lymphocytes have been identified as effector cells . The disease can be successfully treated with combined immunosuppressive therapy or allogeneic hematopoietic stem cell transplantation.

    Hepatitis-associated aplastic anemia (HAA  is a syndrome of bone marrow failure following the development of acute seronegative hepatitis. HAA syndrome most often affects young males who presented severe pancytopenia two to three months after an episode of acute hepatitis. The clinical course of hepatitis is more frequently benign but a fulminant severe course is also described. The bone marrow failure can be explosive and severe and it is usually fatal if untreated, no correlations have been observed between severity of hepatitis and AA.

    In none of the  studies a specific virus could be identified and most cases are seronegative for known hepatitis viruses. The clinical characteristics  and response to immunotherapy indicate a central role for immune-mediated mechanism in the pathogenesis of HAA. The initial

    Full Text Available Acute liver failure (ALF is a devastating condition that occurs in patients who previously had a normal liver. Although the outcome of patients with ALF has improved, without liver transplantation (LT mortality rates remain in the range of 35-50% in different geographical areas and therefore, its treatment remains an unmet need. In the Western world toxic liver injury from acetaminophen remains one of the common causes but, in the East, hepatitis of unknown aetiology remains the most common cause. Treatment options are limited to meticulous attention to multi-organ support, use of N-acetyl cysteine, judicious use of antibiotics, and timely LT.

A WRF, indicated by a change in serum creatinine ≥0.3 mg/mL during the first 5 days, occurred in 360 patients while no‐WRF, indicated by a change <0.3 mg/dL, in 723 patients. Acute kidney injury (AKI) upon admission was defined based on the ratio of the serum creatinine value recorded on admission to the baseline creatinine value and placed into groups based on the degree of AKI: no‐AKI (n = 751), Class R (risk; n = 193), Class I (injury; n = 41), or Class F (failure; n = 98). The patients were assigned to another set of four groups: no‐WRF/no‐AKI (n = 512), no‐WRF/AKI (n = 211), WRF/no‐AKI (n = 239), and WRF/AKI (n = 121). A multivariate logistic regression model found that no‐WRF/AKI and WRF/AKI were independently associated with 365 day mortality (hazard ratio: 1.916; 95% confidence interval: 1.234–2.974 and hazard ratio: 3.622; 95% confidence interval: 2.332–5.624). Kaplan–Meier survival curves showed that the rate of any‐cause death during 1 year was significantly poorer in the no‐WRF/AKI and WRF/AKI groups than in the WRF/no‐AKI and no‐WRF/no‐AKI groups and in Class I and Class F than in Class R and the no‐AKI group. Conclusions The presence of AKI on admission, especially Class I and Class F status, is associated with a poor prognosis despite the lack of a WRF within the first 5 days. The prognostic ability of AKI on admission may be superior to WRF within the first 5 days. PMID:29388735

    The Japanese style of intensive medical care for acute liver failure has yielded high survival rates. The care system comprises artificial liver support (ALS) together with treatment for the underlying disease. Plasma exchange in combination with high-volume hemodiafiltration using an high performance membrane has become the standard ALS system. It is safe, efficiently removing more low and middle molecular weight toxic substances than other methods because of the large volumes of buffer (more than 200 L per session), resulting in recovery from coma in patients with severe fulminant hepatitis, a status comparable with the ahepatic state. This ALS is therefore an effective tool to sustain patients with fulminant hepatitis in a favorable condition until liver function recovers or liver transplantation becomes available. The accompanying treatment for underlying disease serves to limit the liver destruction that hampers regeneration. The treatment has remarkably improved the prognosis for patients with subacute types of fulminant hepatitis, which generally carry a less favorable prognosis than the acute type. This treatment system thus provides more time for physicians to assess the indications for liver transplantation as well as giving the patient a greater chance of undergoing transplantation.

    We present a case of a 63-year-old male who had travelled from South India to United Kingdom (UK) visiting relatives. He had developed episodes of diarrhea, vomiting and fevers while travelling and on assessment in hospital, mild abdominal distension was noted with rapid deterioration to hypovolemic shock. Initial blood test showed a low platelet count with deranged liver function tests (LFTs). It was noted that during admission to intensive care unit (ICU), blood continued to ooze from a previous surgical laparoscopy wound, central and arterial line access sites. Blood results revealed ongoing derangement of clotting and LFT. Computed tomography (CT) scan showed possible acute cholecystitis and a laparoscopy showed an ischemic-looking liver and gut but no significant gallbladder abnormality. The virology screen was positive for dengue virus antibodies IgM and IgG. The patient developed multi-organ failure and deteriorated despite intensive support. Post mortem showed fulminant hepatic failure and acute tubular necrosis of kidneys.

    Full Text Available CD4+ T cell help is critical in maintaining antiviral immune responses and such help has been shown to be sustained in acute resolving hepatitis C. In contrast, in evolving chronic hepatitis C CD4+ T cell helper responses appear to be absent or short-lived, using functional assays.Here we used a novel HLA-DR1 tetramer containing a highly targeted CD4+ T cell epitope from the hepatitis C virus non-structural protein 4 to track number and phenotype of hepatitis C virus specific CD4+ T cells in a cohort of seven HLA-DR1 positive patients with acute hepatitis C in comparison to patients with chronic or resolved hepatitis C. We observed peptide-specific T cells in all seven patients with acute hepatitis C regardless of outcome at frequencies up to 0.65% of CD4+ T cells. Among patients who transiently controlled virus replication we observed loss of function, and/or physical deletion of tetramer+ CD4+ T cells before viral recrudescence. In some patients with chronic hepatitis C very low numbers of tetramer+ cells were detectable in peripheral blood, compared to robust responses detected in spontaneous resolvers. Importantly we did not observe escape mutations in this key CD4+ T cell epitope in patients with evolving chronic hepatitis C.During acute hepatitis C a CD4+ T cell response against this epitope is readily induced in most, if not all, HLA-DR1+ patients. This antiviral T cell population becomes functionally impaired or is deleted early in the course of disease in those where viremia persists.

    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.

    2015-01-01

    BACKGROUND: Osteopontin (OPN) is a novel phosphoglycoprotein expressed in Kupffer cells that plays a pivotal role in activating natural killer cells, neutrophils and macrophages. Measuring plasma OPN levels in patients with acute liver failure (ALF) might provide insights into OPN function...... in the setting of massive hepatocyte injury. METHODS: OPN levels were measured using a Quantikine® ELISA assay on plasma from 105 consecutive ALF patients enrolled by the US Acute Liver Failure Study Group, as well as controls including 40 with rheumatoid arthritis (RA) and 35 healthy subjects both before, and 1...... and 3 days after undergoing spine fusion (SF) surgery as a model for acute inflammation. RESULTS: Median plasma OPN levels across all etiologies of ALF patients were elevated 10- to 30-fold: overall median 1055ng/mL; range: 33-19,127), when compared to healthy controls (median in pre-SF patients: 41ng...

    2014-01-01

    Objective As acute liver failure (ALF) and chronic liver disease (cirrhosis) continue to increase in prevalence, we will see more cases of hepatic encephalopathy. Primary care physician are often the first to suspect it, since they are familiar with the patient’s usual physical and mental status. This serious complication typically occurs in patients with severe comorbidities and needs multidisciplinary evaluation and care. Hepatic encephalopathy should be considered in any patient with acute liver failure and cirrhosis who presents with neuropsychiatric manifestations, decrease level of consciousness (coma), change of personality, intellectual and behavioral deterioration, speech and motor dysfunction. Every cirrhotic patient may be at risk; potential precipitating factors should be addressed in regular clinic visits. The encephalopathy of liver disease may be prominent, or can be present in subtle forms, such as decline of school performance, emotional outbursts, or depression. “Subtle form” of hepatic encephalopathy may not be obvious on clinical examination, but can be detected by neurophysiologic and neuropsychiatric testing.

    As a phenylpropanoid and dibenzylbutyrolactone lignan present in medical plants, such as those used in traditional Chinese herbal medicine, including Arctium lappa (Niubang), arctigenin exhibits antimicrobial, anti-inflammatory, and anticancer activities. In this study, we investigated the protective role of arctigenin in Concanavalin A (ConA)-induced acute hepatitis in mice. Arctigenin remarkably reduced the congestion and necroinflammation of livers, and improved hepatic function (ALT and AST) in ConA-induced acute hepatitis in vivo. The infiltration of CD4 T, NKT and macrophages into the livers was found to be reduced with arctigenin treatment. Arctigenin suppressed ConA-induced T lymphocyte proliferations that might have resulted from enhanced IL-10 production by macrophages and CD4 T cells. These results suggested that arctigenin could be a powerful drug candidate for acute hepatitis through immune suppression. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    Full Text Available 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.

    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.

    Brain oedema leading to intracranial hypertension occurs in a significant proportion of patients with acute liver failure in whom it is a leading cause of death. Although precise pathogenic mechanisms associated to this severe complication remain incompletely understood, increasing evidence points to gut-derived neurotoxins including ammonia as key mediators in cerebral osmotic and perfusion disturbances. The management of brain oedema and intracranial hypertension requires a multidisciplinar approach in a center where liver transplantation is available, as this option is the only treatment modality that provides improvement in outcome. This article reviews the most common causes of acute liver failure and the standard of supportive care management, and describes future potential therapeutic aspects of brain oedema and intracranial hypertension.

    Acute hepatitis A (AHA) and acute hepatitis B (AHB) are caused by an acute infection of the hepatitis A virus and the hepatitis B virus, respectively. In both AHA and AHB, liver injury is known to be mediated by immune cells and cytokines. In this study, we measured serum levels of various cytokines and T-cell cytotoxic proteins in patients with AHA or AHB to identify liver injury-associated cytokines. Forty-six patients with AHA, 16 patients with AHB, and 14 healthy adults were enrolled in the study. Serum levels of 17 cytokines and T-cell cytotoxic proteins were measured by enzyme-linked immunosorbent assays or cytometric bead arrays and analyzed for correlation with serum alanine aminotransferase (ALT) levels. Interleukin (IL)-18, IL-8, CXCL9, and CXCL10 were significantly elevated in both AHA and AHB. IL-6, IL-22, granzyme B, and soluble Fas ligand (sFasL) were elevated in AHA but not in AHB. In both AHA and AHB, the serum level of CXCL10 significantly correlated with the peak ALT level. Additionally, the serum level of granzyme B in AHA and the serum level of sFasL in AHB correlated with the peak ALT level. We identified cytokines and T-cell cytotoxic proteins associated with liver injury in AHA and AHB. These findings deepen the existing understanding of immunological mechanisms responsible for liver injury in acute viral hepatitis.

    The liver scintigraphies of five patients with fulminant hepatitis were examined. Scintiphotos using sup(99m)Tc-phytate were taken within two weeks after the onset. Scintiphotos of 12 normal subjects, 11 cases with acute hepatitis, 17 cases with liver cirrhosis were served as control. Their scintiphotos showed reduction of the size, well-maintained uptake, mostly homogenous RI distribution, and no left lobe enlargement, which could differentiate them from the chronic liver dysfunction. In one of the cases chronological changes in liver scintigraphy were observed. The size of the liver was reduced progressively until the 16th day and re-enlarged at the 30th day and thereafter. Three indices [S/W, (R + L)/W, and L/R] were calculated. S: area of liver, R or L: longitudinal length of the right or left lobe, W: body width. Relative size of the liver expressed by S/W or (R + L)/W showed significant reduction in fulminant hepatitis compared with acute hepatitis. However, they were not different significantly from those of normal subjects. Except for liver cirrhosis, L/R (left lobe swelling index) did not show significant differences among fulminant hepatitis, normal subjects, and acute hepatitis. These indices were also useful in follow-up study of the liver scintigraphy. The liver scintigraphy in the early phase of fulminant hepatitis seems to reflect the degree of massive hepatic necrosis. It is also useful to differentiate chronic hepatic failure. Apparant reduction in scintigraphical liver size seems to suggest poor prognosis, however, it should also kept in mind that the size of the liver in this condition might change quite rapidly and greatly.

    2016-01-01

    Full Text Available A 38-year-old African American woman presenting with acute abdominal pain and nonobstructive renal failure was found to have an enlarged fibroid uterus. A differential for sepsis was considered. Lab evaluation revealed an elevated creatinine and myoglobin level at 3.9 mg/dL and 2140 ng/mL, respectively. Ongoing hemodynamic instability mandated surgery for acute abdomen. A 25 cm fibroid uterus was extirpated through a total abdominal hysterectomy. Immediate improvement of acute nephropathy mirrored the postoperative decline in serum myoglobin levels. Myoglobinemia from a massive degenerating fibroid is associated with nonobstructive acute renal failure.

    Full Text Available ObjectiveTo analyze the prognostic factors in acute-on-chronic liver failure (ACLF patients with hepatic encephalopathy (HE and to explore the risk factors for prognosis. MethodsA retrospective analysis was performed on 106 ACLF patients with HE who were hospitalized in our hospital from January 2010 to July 2013. The patients were divided into improved group and deteriorated group. The univariate indicators including age, sex, laboratory indicators [total bilirubin (TBil, albumin (Alb, alanine aminotransferase (ALT, aspartate amino-transferase (AST, and prothrombin time activity (PTA], the stage of HE, complications [persistent hyponatremia, digestive tract bleeding, hepatorenal syndrome (HRS, ascites, infection, and spontaneous bacterial peritonitis (SBP], and plasma exchange were analyzed by chi-square test or t-test. Indicators with statistical significance were subsequently analyzed by binary logistic regression. ResultsUnivariate analysis showed that ALT (P=0.009, PTA (P=0.043, the stage of HE (P=0.000, and HRS (P=0.003 were significantly different between the two groups, whereas differences in age, sex, TBil, Alb, AST, persistent hyponatremia, digestive tract bleeding, ascites, infection, SBP, and plasma exchange were not statistically significant (P>0.05. Binary logistic regression demonstrated that PTA (b=-0097, P=0.025, OR=0.908, HRS (b=2.279, P=0.007, OR=9.764, and the stage of HE (b=1873, P=0.000, OR=6.510 were prognostic factors in ACLF patients with HE. ConclusionThe stage of HE, HRS, and PTA are independent influential factors for the prognosis in ACLF patients with HE. Reduced PTA, advanced HE stage, and the presence of HRS indicate worse prognosis.

    HBV vaccine contains the 'a' determinant region, the major immune-target of antibodies (anti-HBs). Failure of immunization may be caused by vaccine-induced or spontaneous 'a' determinant surface gene mutants. Here, we evaluate the possible lack of protection by HBV vaccine, describing the case of an acute hepatitis B diagnosed in a 55-year-old Caucasian male unpaid blood donor, vaccinated against HBV. Sequencing data for preS-S region revealed multiple point mutations. Of all the substitutions found, Q129H, located in the "a" determinant region of HBsAg, can alter antigenicity, leading to mutants. This mutant may cause vaccine failure especially when associated with high viremia of infecting source. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Objectives: There is a paucity of data on acute decompensated heart failure (ADHF in Indian patients. We herein report the in-hospital and 6-month outcome of Indian patients admitted with ADHF. Methods: We prospectively enrolled consecutive patients with ADHF due to systolic dysfunction in the acute failure registry and followed them up for at least 6 months. We analyzed the data on death and hospitalization of the first 90 patients on death and hospitalization over 6-months. Results: A total of 90 patients were enrolled with a mean age of 53.5 ± 17. 7 years and the majority were male (63%. The mean left ventricular ejection fraction was 29.2± 11.9%. The in hospital mortality was 30.8%. Postdischarge 6-month major adverse event (re-hospitalization/mortality combined and mortality rates were 39.5% and 26.3%, respectively. Conclusions: These data from a single referral center provide insights into the current status of acute HF care in India. We report a higher in-hospital and follow-up mortality rates in ADHF patients who present at younger ages than reported in Western literature.

    Full Text Available Objective: to evaluate the efficiency of methods for diagnosing and treating critically ill patients with acute respiratory failure (ARF in acute poisoning by neurotropic substances. Subjects and methods. Two hundred and thirty-three patients with acute severe intoxication with neurotropic poisons were examined. All the patients were admitted for toxic-hypoxic coma and ARF; in this connection all the patients underwent artificial ventilation (AV. The patients were divided into 3 groups: 1 those in whom the traditional treatments (AV, detoxifying therapy, and infusional and cardiotropic support could restore the basic parameters of vital functions, as judged from the recovered oxygenation index; these patients had no metabolic shifts; 2 those who had signs of pulmonary hyperhydration, low cardiac output and moderate metabolic disorders, as suggested by elevated lactate levels; 3 seriously ill patients in whom the interval between the time of poisoning to care delivery was more than 20 hours; the patients of this group had the most significant metabolic disorders. Results. Correction of ARF in critically ill patients with acute poisoning should include, in addition to the rational parameters of AV and detoxifying therapy, agents for targeted therapy for sequels of hypoxia and energy deficiency states. For maximally rapid and effective oxygen transport recovery, the addition of perfluorane to the complex therapy cardinally improves the results of treatment and reduces mortality rates. Conclusion. The complexity of the pathogenesis of ARF and its sequels is a ground for diagnosing and correcting not only ventilation disturbances, but also pulmonary microcirculatory disorders and metabolic disturbances. Key words: acute intoxication with neu-rotropic poisons, acute respiratory failure, pulmonary hyperhydration, hypoxia, metabolic disturbances.

    Acute kidney injury (AKI) is a common complication in cardiac surgery and coronary angiography, which worsens patients' prognosis. The diagnosis is based on the increase in serum creatinine, which is delayed. It is necessary to identify and validate new biomarkers that allow for early and effective interventions. To assess the sensitivity and specificity of neutrophil gelatinase-associated lipocalin in urine (uNGAL), interleukin-18 (IL-18) in urine and cystatin C in serum for the early detection of AKI in patients with acute coronary syndrome or heart failure, and who underwent cardiac surgery or catheterization. The study included 135 patients admitted to the intensive care unit for acute coronary syndrome or heart failure due to coronary or valvular pathology and who underwent coronary angiography or cardiac bypass surgery or valvular replacement. The biomarkers were determined 12 hours after surgery and serum creatinine was monitored during the next six days for the diagnosis of AKI. The area under the ROC curve (AUC) for NGAL was 0.983, and for cystatin C and IL-18 the AUCs were 0.869 and 0.727, respectively. At a cut-off of 31.9 ng/ml for uNGAL the sensitivity was 100% and the specificity was 91%. uNGAL is an early marker of AKI in patients with acute coronary syndrome or heart failure and undergoing cardiac surgery and coronary angiography, with a higher predictive value than cystatin C or IL-18.

Similar to the experience in patients with cerebral edema after other neurologic...... insults, hypothermia reduces cerebral edema and intracranial hypertension in patients with acute liver failure by decreasing splanchnic ammonia production, restoring normal regulation of cerebral hemodynamics, and lowering oxidative metabolism within the brain. Hypothermia may also ameliorate the degree...... of liver injury. Hypothermia has not been adequately studied for its safety and theoretically may increase the risk of infection, cardiac dysrhythmias, and bleeding, all complications independently associated with acute liver failure. Therefore, although an ample body of experimental and human data...

    Acute heart failure (AHF) is a potentially life-threatening condition that may arise as a deterioration of a previous heart failure or may be the first presentation of heart failure. Several causes or precipitating factors have been listed, as well as different mechanisms have been described, thus leading to a broad spectrum of clinical presentations. Symptoms and signs of AHF have a strong clinical and prognostic significance and are kept into consideration to guide disease management. In particular, a higher clinical severity or a worse prognosis are associated with lower blood pressure levels, fluid overload, evidence of myocardial ischemia or renal impairment. Putatively, interventions addressed to restore these factors may play a role in the management of AHF.

    The purpose of this study was to report the potential of hepatic artery stent grafting in cases of acute hemorrhage of the gastroduodenal artery stump following pancreatic head resection. Five consecutive male patients were treated because of acute, life-threatening massive bleeding. Instead of re-operation, emergency angiography, with the potential of endovascular treatment, was performed. Because of bleeding from the hepatic artery, a stent graft (with the over-the-wire or monorail technique) was implanted to control the hemmorhage by preserving patency of the artery. The outcome was evaluated. In all cases, the hepatic artery stent grafting was successfully performed, and the bleeding was immediately stopped. Clinically, immediately after the procedure, there was an obvious improvement in the general patient condition. There were no immediate procedure-related complications. Completion angiography (n=5) demonstrated control of the hemorrhage and patency of the hepatic artery and the stent graft. Although all patients recovered hemodynamically, three individuals died 2 to 10 days after the procedure. The remaining two patients survived, without the need for re-operation. Transluminal stent graft placement in the hepatic artery is a safe and technically feasible solution to control life-threatening bleeding of the gastroduodenal artery stump. (orig.)

    Acute hyperammonemic encephalopathy is a rare toxic encephalopathy caused by accumulated plasma ammonia. A few literatures are reported about MRI findings of acute hyperammonemic encephalopathy. It is different from the well-known chronic hepatic encephalopathy. The clinical symptom and MRI findings of acute hyperammonemic encephalopathy can be reversible with proper treatment. Acute hepatic encephalopathy involves the cingulate cortex, diffuse cerebral cortices, insula, bilateral thalami on diffusion-weighted imaging (DWI), and fluid-attenuated inversion-recovery. Acute hepatic encephalopathy might mimic hypoxic-ischemic encephalopathy because of their similar predominant involving sites. We experienced 2 cases of acute hyperammonemic encephalopathy consecutively. They showed restricted diffusion at the cingulate cortex, cerebral cortices, insula, and bilateral dorsomedial thalami on DWI. One patient underwent acute fulminant hepatitis A, the other patient with underlying chronic liver disease had acute liver failure due to hepatotoxicity of tuberculosis medication. In this report, we presented the characteristic features of DWI in acute hyperammonemic encephalopathy. In addition, we reviewed articles on MRI findings of acute hyperammonemic encephalopathy.

    Acute renal failure (ARF) may be due to obstructive uropathy or renal parenchymal disease. Twenty-five children with acute renal failure secondary to renal parenchymal disease underwent ultrasonographic examination of the kidneys. Changes of renal size and cortical echogenicity were correlated with renal function. All patients presented with bilaterally enlarged kidneys with the exception in renal function resulted in normalization of renal size. With regard to cortical echogenicity two groups were formed. Group A comprised 11 patients whose kidneys had the same echogenicity as the liver, while in group B the kidneys were more echogenic (14 patients). Cortical echogenicity was always increased. Determination of creatinine levels showed a statistically significant difference between group A (3.32 mg% ± 1.40 S.D.) and group B (5.95 mg% ± 1.96 S.D.), p < 0.001. Changes in renal function were paralleled by rapid changes in renal size and cortical echogenicity. (orig.)

    The pregnancy-associated immunological and hormonal changes may alter the immune response to infectious agents, including hepatitis viruses. Therefore, this phenomenon may affect the clinical course and the outcome of acute viral hepatitis in pregnant women. For this reason, we have focused on epidemiological and pathogenetic aspects of the fulminant liver failure caused by acute viral hepatitis reviewing PubMED in April of 2017. Although all the viruses might cause a fulminant AVH in a pregnant woman, the large majority of fulminant failure reported in the literature had been related to Hepatits E Virus mainly and had been concentrated in Indian subcontinent and some African areas, whereas the problem seems to be very low or absent in the remaining geographical areas. However, the rate of maternal mortality due to fulminant E hepatitis may vary inside the endemic areas of India and Africa, likely due to the circulation of HEV genotypes with different degree of virulence. The other hepatitis viruses have not been reported to cause a greater risk for fulminant hepatitis in pregnant women respect to non pregnant ones, except Herpes Simplex Virus, that has been associated to some cases of fatal hepatitis in absence of a prompt antiviral therapy.

    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.

  13. Contrast media induced acute renal failure in diabetics

    Dehydration, preexisting renal insufficiency, multiple myeloma and insulin-dependent diabetes mellitus are known risk factors for a radiocontrast medium induced acute renal failure. In 90% of patients with insulin-dependent diabetes mellitus, renal insufficiency and proteinuria, a further detoriation of renal function can be expected after i.v. administration of radiocontrast medium. Recent concepts on the genesis of acute renal failure after radiocontrast medium in multiple myeloma emphasize the role of tubular blocade (tubular precipitation of myeloma protein with contrast medium). In insulin-dependent diabetic patients we found altered carbohydrate composition of urinary Tamm Horsfall Protein (THP), with increased glucose and diminished N-acetyl-neuraminicacid content. This was paralleled by a difference in an in-vitro system of coprecipitation where THP of diabetes triggered more pronounced calcium dependent coprecipitation of contrast medium and albumin. These in-vitro findings might be important for the explanation of the genesis of radiocontrast medium-induced acute renal failure in insulin-dependent diabetes mellitus. (orig.) [de

    A low or moderate expired tidal volume can be difficult to achieve during noninvasive ventilation for de novo acute hypoxemic respiratory failure (i.e., not due to exacerbation of chronic lung disease or cardiac failure). We assessed expired tidal volume and its association with noninvasive ventilation outcome. Prospective observational study. Twenty-four bed university medical ICU. Consecutive patients receiving noninvasive ventilation for acute hypoxemic respiratory failure between August 2010 and February 2013. Noninvasive ventilation was uniformly delivered using a simple algorithm targeting the expired tidal volume between 6 and 8 mL/kg of predicted body weight. Expired tidal volume was averaged and respiratory and hemodynamic variables were systematically recorded at each noninvasive ventilation session. Sixty-two patients were enrolled, including 47 meeting criteria for acute respiratory distress syndrome, and 32 failed noninvasive ventilation (51%). Pneumonia (n = 51, 82%) was the main etiology of acute hypoxemic respiratory failure. The median (interquartile range) expired tidal volume averaged over all noninvasive ventilation sessions (mean expired tidal volume) was 9.8 mL/kg predicted body weight (8.1-11.1 mL/kg predicted body weight). The mean expired tidal volume was significantly higher in patients who failed noninvasive ventilation as compared with those who succeeded (10.6 mL/kg predicted body weight [9.6-12.0] vs 8.5 mL/kg predicted body weight [7.6-10.2]; p = 0.001), and expired tidal volume was independently associated with noninvasive ventilation failure in multivariate analysis. This effect was mainly driven by patients with PaO2/FIO2 up to 200 mm Hg. In these patients, the expired tidal volume above 9.5 mL/kg predicted body weight predicted noninvasive ventilation failure with a sensitivity of 82% and a specificity of 87%. A low expired tidal volume is almost impossible to achieve in the majority of patients receiving noninvasive ventilation

    Acute tubulo-interstitial nephritis (ATIN) is an important cause of acute renal failure, where renal impairement tends to be variable but recovery is the rule. End-stage renal failure (ESRF) has been rarely reported as a complication of ATIN. We report here a case of idiopathic ATIN that resulted in severe acute renal failure. The patient developed ESRF, which required permanent renal replacement therapy. (author)

    Hepatic infarcts or abscesses occur after hepatic artery interruption. We explored the mechanisms of hepatic deprivation-induced acute liver injury and determine whether partial portal vein arterialization attenuated this injury in rats. Male Sprague-Dawley rats underwent either complete hepatic arterial deprivation or partial portal vein arterialization, or both. Hepatic ischemia was evaluated using biochemical analysis, light microscopy, and transmission electron microscopy. Hepatic ATP levels, the expression of hypoxia- and inflammation-associated genes and proteins, and the expression of bile transporter genes were assessed. Complete dearterialization of the liver induced acute liver injury, as evidenced by the histological changes, significantly increased serum biochemical markers, decreased ATP content, increased expression of hypoxia- and inflammation-associated genes and proteins, and decreased expression of bile transporter genes. These detrimental changes were extenuated but not fully reversed by partial portal vein arterialization, which also attenuated ductular reaction and fibrosis in completely dearterialized rat livers. Collectively, complete hepatic deprivation causes severe liver injury, including bile infarcts and biloma formation. Partial portal vein arterialization seems to protect against acute ischemia-hypoxia-induced liver injury.

    Acute Renal Failure (ARF) is characterized by a rapid decline of the glomerular filtration rate, due to hypotension (prerenal ARF), obstruction of the urinary tract (post-renal ARF) or renal parenchymal disease (renal ARF). The differential diagnosis among different causes of ARF is based on anamnesis, clinical symptoms and laboratory data. Usually ultrasound (US) is the only imaging examination performed in these patients, because it is safe and readily available. In patients with ARF gray scale US is usually performed to rule out obstruction since it is highly sensitive to recognize hydronephrosis. Patients with renal ARF have no specific changes in renal morphology. The size of the kidneys is usually normal or increased, with smooth margins. Detection of small kidneys suggests underlying chronic renal pathology and worse prognosis. Echogenicity and parenchymal thickness are usually normal, but in some cases there are hyperechogenic kidneys, increased parenchymal thickness and increased cortico-medullary differentiation. Evaluation of renal vasculature with pulsed Doppler US is useful in the differential diagnosis between prerenal ARF and acute tubular necrosis (ATN), and in the diagnosis of renal obstruction. Latest generation US apparatus allow color Doppler and power Doppler evaluation of renal vasculature up to the interlobular vessels. A significant, but non specific, reduction in renal perfusion is usually appreciable in the patients with ARF. There are renal pathologic conditions presenting with ARF in which color Doppler US provides more specific morphologic and functional information. In particular, color Doppler US often provides direct or indirect signs which can lead to the right diagnosis in old patients with chronic renal insufficiency complicated with ARF, in patients with acute pyelonephritis, hepatic disease, vasculitis, thrombotic microangiopathies, and in patients with acute thrombosis of the renal artery and vein.

    To estimate whether the reported increase in obstetric acute renal failure in the United States was attributable to a concurrent rise in postpartum hemorrhage, a change in other risk factors, or changes in the diagnosis of acute renal failure. We conducted a retrospective cohort study to quantify temporal trends in acute renal failure among 10,969,263 hospital deliveries in the United States from 1999 to 2011 using data from the Nationwide Inpatient Sample. Dialysis and maternal death were used as markers of severe acute renal failure. Logistic regression was used to determine whether changes in risk factors explained the temporal rise in acute renal failure. Obstetric acute renal failure rose from 2.4 to 6.3 per 10,000 deliveries between 1999-2001 and 2010-2011, a 10% yearly increase (95% confidence interval [CI] 8-11%) and adjustment for risk factors only partially explained the rise (adjusted yearly increase 6%, 95% CI 5-8%). The overall severity of acute renal failure decreased, although acute renal failure with dialysis rose from 0.27 to 0.36 per 10,000 deliveries (P for trend=.01), and acute renal failure associated with maternal death increased from 0.13 to 0.23 per 10,000 deliveries (P for trend=.01). The temporal increase in acute renal failure with dialysis was abolished by adjustment for chronic kidney disease and chronic hypertension. Changes in diagnosis or ascertainment have led to substantial increases in obstetric acute renal failure, whereas increases in chronic kidney disease and chronic hypertension among pregnant women have resulted in modest but significant increases in acute renal failure with dialysis.

  2. Hepatic angiography: Portal hypertension

    1985-01-01

    Portal hypertension is usually a manifestation of underlying hepatic parenchymal disease, although it may be secondary to portal or hepatic venous thrombosis and rarely to hyperdynamic portal states. Portal hypertension may present as encephalopathy, ascites, jaundice, hepatic failure, or catastrophic upper gastrointestinal hemorrhage. Radiologic investigation should include indirect or direct measurements of portal pressure, assessment of portal venous perfusion, visualization of collaterals, and demonstration of arterial and venous anatomy for potential shunt procedure. Following survival of initial variceal bleeding, the most effective procedure to prevent recurrent hemorrhage is a shunt to decompress the varices. The decision whether to intervene medically or surgically during the acute hemorrhagic episode as well as the type of shunt used to prevent future hemorrhage is the subject of continuing controversy

    Highlights: • We report our experiences with stent-grafts for the treatment of acute hemorrhage from the hepatic artery or the stump of the gastroduodenal artery. • The technical success of stent-graft implantation was 88%. • The bleeding ceased immediately after stent-graft implantation in 88%. • The complication rate was 21%. - Abstract: Purpose: We evaluated the technical success and clinical efficacy of stent-graft implantation for the emergency management of acute hepatic artery bleeding. Methods: Between January 2010 and July 2013, 24 patients with hemorrhage from the hepatic artery were scheduled for emergency implantation of balloon expandable stent-grafts. The primary study endpoints were technical and clinical success, which were defined as successful stent-graft implantation with sealing of the bleeding site at the end of the procedure, and cessation of clinical signs of hemorrhage. The secondary study endpoints were complications during the procedure or at follow-up and 30-day mortality rate. Results: In 23 patients, hemorrhage occurred after surgery, and in one patient hemorrhage occurred after trauma. Eight patients had sentinel bleeding. In most patients (n = 16), one stent-graft was implanted. In six patients, two overlapping stent-grafts were implanted. The stent-grafts had a target diameter between 4 mm and 7 mm. Overall technical success was 88%. The bleeding ceased after stent-graft implantation in 21 patients (88%). The mean follow-up was 137 ± 383 days. In two patients, re-bleeding from the hepatic artery occurred during follow-up after 4 and 29 days, respectively, which could be successfully treated by endovascular therapy. The complication rate was 21% (minor complication rate 4%, major complication rate 17%). The 30-day mortality rate was 21%. Conclusions: Implantation of stent-grafts in the hepatic artery is an effective emergency therapy and has a good technical success rate for patients with acute arterial hemorrhage.

    Full Text Available Traditional herbal medicine is a global phenomenon especially in the resource poor economy where only the very rich can access orthodox care. These herbal products are associated with complications such as acute renal failure and liver damage with a high incidence of mortalities and morbidities. Acute renal failure from the use of herbal remedies is said to account for about 30–35% of all cases of acute renal failure in Africa. Most of the herbal medications are not usually identified, but some common preparation often used in Nigeria includes “holy water” green water leaves, bark of Mangifera indica (mango, shoot of Anacardium occidentale (cashew, Carica papaya (paw-paw leaves, lime water, Solanum erianthum (Potato tree, and Azadirachta indica (Neem trees. We report a rare case of a young man who developed acute renal failure two days after ingestion of Chinese herb for “body cleansing” and general wellbeing. He had 4 sessions of haemodialysis and recovered kidney function fully after 18 days of admission.

    Acute-on-chronic liver failure (ACLF) is a severe, life-threatening complication, and new and efficient therapeutic strategies for liver failure are urgently needed. Mesenchymal stem cell (MSC) transfusions have been shown to reverse fulminant hepatic failure in mice and to improve liver function in patients with end-stage liver diseases. We assessed the safety and initial efficacy of umbilical cord-derived MSC (UC-MSC) transfusions for ACLF patients associated with hepatitis B virus (HBV) infection. A total of 43 ACLF patients were enrolled for this open-labeled and controlled study; 24 patients were treated with UC-MSCs, and 19 patients were treated with saline as controls. UC-MSC therapy was given three times at 4-week intervals. The liver function, adverse events, and survival rates were evaluated during the 48-week or 72-week follow-up period. No significant side effects were observed during the trial. The UC-MSC transfusions significantly increased the survival rates in ACLF patients; reduced the model for end-stage liver disease scores; increased serum albumin, cholinesterase, and prothrombin activity; and increased platelet counts. Serum total bilirubin and alanine aminotransferase levels were significantly decreased after the UC-MSC transfusions. UC-MSC transfusions are safe in the clinic and may serve as a novel therapeutic approach for HBV-associated ACLF patients. PMID:23197664

    2010-01-01

    Full Text Available A 28-year-old female who underwent live donor liver transplantation 3 years prior presented after percutaneous liver biopsy with abdominal and shoulder pain, nausea, vomiting, and elevated liver enzymes. Computed tomography (CT showed an intrahepatic and subcapsular hematoma. There was a progressive increase in liver enzymes, bilirubin, and INR and a decline in hemoglobin. Subsequent CT imaging revealed flattening of the portal vein consistent with compression by the enlarging hematoma. Liver failure ensued and the patient required urgent retransplantation. The explant demonstrated ischemic necrosis of greater than 90% of the liver parenchyma. We report this case of “Hepatic Compartment Syndrome” leading to fulminant hepatic failure.

    Paraoxonase (PON), a high density lipoprotein (HDL) associated enzyme, is believed to protect against the oxidation of low density lipoprotein (LDL) and hence affects the risk of vascular disease. PON is sensitive to oxidants and is inactivated by oxidized lipids, and thus it can be postulated that increased oxidative stress may decrease plasma PON activity in patients with chronic renal failure (CRF) and hepatic insufficiency (HI). Moreover, in CRF and HI patients, in contrast to normal individuals, higher levels of plasma biochemical parameters and liver enzymes had an inverse correlation with PON activity. In this study we aimed to investigate PON activity, total bilirubin, creatinine, urea and liver enzymes alanine aminotransferase and alkaline phosphatase that are the index of renal and hepatic insufficiency. We have analyzed plasma from pre-dialysis patients and compared the results with the normal individuals. We observed a positive association of PON activity with that of the disease state i.e. the activity of this enzyme was significantly lower in the patients (p < 0.001). Furthermore, the indicators of renal and hepatic insufficiency were significantly elevated as compared to the normal subjects. Based on our results we conclude that in CRF and HI, in contrast to normal individuals, higher levels of plasma biochemical parameters and liver enzymes had inverse correlation with PON activity. Collectively, these findings may add details to the understanding of the role that PON plays in chronic renal failure and hepatic insufficiency. (author)

In view of the effects of cannabinoids in a thioacetamide-induced model of hepatic encephalopathy and liver disease and the beneficial effect of capsaicin (a TRPV1 agonist) in liver disease, we assumed that capsaicin may also affect hepatic encephalopathy. Experimental approach: Fulminant hepatic failure was induced in mice by thioacetamide and 24 h later, the animals were injected with one of the following compound(s): 2-arachidonoylglycerol (CB1, CB2 and TRPV1 receptor agonist); HU308 (CB2 receptor agonist), SR141716A (CB1 receptor antagonist); SR141716A+2-arachidonoylglycerol; SR144528 (CB2 receptor antagonist); capsaicin; and capsazepine (TRPV1 receptor agonist and antagonist respectively). Their neurological effects were evaluated on the basis of activity in the open field, cognitive function in an eight-arm maze and a neurological severity score. The mice were killed 3 or 14 days after thioacetamide administration. 2-arachidonoylglycerol and 5-hydroxytryptamine (5-HT) levels were determined by gas chromatography-mass spectrometry and high-performance liquid chromatography with electrochemical detection, respectively. Results: Capsaicin had a neuroprotective effect in this animal model as shown by the neurological score, activity and cognitive function. The effect of capsaicin was blocked by capsazepine. Thioacetamide induced astrogliosis in the hippocampus and the cerebellum and raised brain 5-hydroxytryptamine levels, which were decreased by capsaicin, SR141716A and HU-308. Thioacetamide lowered brain 2-arachidonoylglycerol levels, an effect reversed by capsaicin. Conclusions: Capsaicin improved both liver and brain dysfunction caused by thioacetamide, suggesting that both the endocannabinoid and the vanilloid systems play important roles in hepatic encephalopathy. Modulation of these systems may have therapeutic value. PMID:19764982

    Hepatic encephalopathy describes the array of neurological alterations that occur during acute liver failure or chronic liver injury. While key players in the pathogenesis of hepatic encephalopathy, such as increases in brain ammonia, alterations in neurosteroid levels, and neuroinflammation, have been identified, there is still a paucity in our knowledge of the precise pathogenic mechanism. This review gives a brief overview of our understanding of the pathogenesis of hepatic encephalopathy and then summarizes the significant recent advances made in clinical and basic research contributing to our understanding, diagnosis, and possible treatment of hepatic encephalopathy. A literature search using the PubMed database was conducted in May 2017 using “hepatic encephalopathy” as a keyword, and selected manuscripts were limited to those research articles published since May 2014. While the authors acknowledge that many significant advances have been made in the understanding of hepatic encephalopathy prior to May 2014, we have limited the scope of this review to the previous three years only.

    Hepatitis A virus (HAV) and Hepatitis E virus (HEV) are both enterically transmitted, resulting in acute viral hepatitis (AVH) in developing countries. They pose major health problems in our country. This study was done to determine prevalence of HAV and HEV in patients presenting with AVH and the co-infection of HAV and HEV in these patients. A cross-sectional study of 2-years duration was conducted in the Department of Microbiology, KMC, Mangalore. A non-random sampling of 958 patients presenting with AVH was considered in the study. On the basis of history, serum samples were analysed for IgM anti-HAV and IgM anti-HEV for the detection of HAV and HEV, respectively using commercially available ELISA kits. Data collected was analysed by using Statistical Package for the Social Sciences (SPSS) version 11.5. The seroprevalence of HAV- and HEV-positive patients were 19.31% and 10.54%, respectively. The seroprevalence of both HAV and HEV in patients with acute viral hepatitis was 11.5%. The prevalence of HAV and HEV among males (68% and 31%) was higher than in females (31% and 20%) and was predominantly seen among young adults. These infections were predominantly seen during end of monsoons and beginning of winter. Though the prevalence of HAV is much higher than that of HEV, co-infection rate of 11.5% mandates the screening for HEV which will be of immense importance in pregnant women and improving levels of personal hygiene among higher socio-economic population. These data will be essential for planning of future vaccination strategies and for better sanitation programme in this part of the country.

    Full Text Available Introduction. Acute heart failure (AHF is one of the most common diseases in emergency medicine, associated with poor prognosis and high in-hospital and long-term mortality. Objective. To investigate clinical presentation of patients with de novo AHF and acute worsening of chronic heart failure (CHF and to identify differences in blood levels of biomarkers and echocardiography findings. Methods. This prospective study comprised 64 consecutive patients being grouped according to the onset of the disease into patients with the de novo AHF (45.3%, and patients with acute worsening of CHF (54.7%. Results. Acute congestion (60% was the most common manifestation of de novo AHF, whereas pulmonary oedema (43.1% was the most common manifestation of acutely decompensated CHF. Patients with acutely decompensated CHF had significantly higher blood values of creatinine (147.10 vs 113.16 μmol/l; p<0.05, urea (12.63 vs 7.82 mmol/l; p<0.05, BNP (1440.11 vs 712.24 pg/ml; p<001 and NTproBNP (9097.00 vs 2827.70 pg/ml; p<0.01 on admission, and lower values of M-mode left ventricular ejection fraction (LVEF during hospitalization (49.44% vs 42.94%; p<0.05. The follow-up after one year revealed still significantly higher BNP (365.49 vs 164.02 pg/ ml; p<0.05 and lower average values of both LVEF in patients with acutely worsened CHF (46.62% vs 54.41% and 39.52% vs 47.88%; p<0.05. Conclusion. Considering differences in clinical severity on admission, echocardiography and natriuretic peptide values during hospitalization and after one year follow-up, de novo AHF and acutely worsened CHF are two different subgroups of the same syndrome.

    Computerized sequential radionuclide angiography was used to analyze the first pass kinetics of peripherally injected bolus of Tc-99m-pertechnetate. The relative arterial/total hepatic blood flow, the Hepatic Perfusion Index (HPI%), was determined in normal subjects while 20 cases of Acute Viral Hepatitis (AVH) were studied serially. In addition, biochemical blood analysis as also carried out. The mean value of HPI in first study of all patients was 61.23% in comparison to 31.12% of control group. The patients were divided into three groups, based upon the duration elapsed between the onset of symptoms and the first study. HPI was found significantly high in first study of each group as compared to controls. In first group there was no significant correlation of mean HPI with other biochemical parameters. In second and third groups, significant correlation were observed between the mean HPI and serum bilirubin, serum alanine trans-aminase with mean HPI in the third group. The serum proteins correlated negatively with HPI in second group. This technique offers a simple, rapid, non-invasive and quantitative method to determine a new index which mostly behaves like other biochemical parameter and can be used to follow the course of acute viral hepatitis.

    Guaifenesin is a common nonprescription medication that has been implicated in drug-induced nephrolithiasis. Dextromethorphan, a nonprescription antitussive found in some guaifenesin-containing preparations, is increasingly recognized as a substance of abuse by many youth and young adults. Renally excreted medications known to have poor solubility in urine have the potential to precipitate when ingested in large quantity, leading to acute obstruction of the ureters and renal failure. We describe the case of a 22-year-old male who developed severe bilateral flank pain, hematuria, and oliguria after an isolated recreational ingestion of guaifenesin and dextromethorphan. The patient was found to have bilateral ureteral obstruction and acute renal failure, suspected to be secondary to precipitation of medication metabolites in the urine. This case highlights the potential for acute renal failure secondary to guaifenesin and dextromethorphan abuse. Copyright © 2014 Elsevier Inc. All rights reserved.

    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. Crown Copyright © 2016. Published by Elsevier Ireland Ltd. All rights reserved.

  19. Current concepts in the assessment and treatment of hepatic encephalopathy.

    2012-02-01

    Hepatic encephalopathy (HE) is defined as a metabolically induced, potentially reversible, functional disturbance of the brain that may occur in acute or chronic liver disease. Standardized nomenclature has been proposed but a standardized approach to the treatment, particularly of persistent, episodic and recurrent encephalopathy associated with liver cirrhosis has not been proposed. This review focuses on the pathogenesis and treatment of HE in patients with cirrhosis. The pathogenesis and treatment of hepatic encephalopathy in fulminant hepatic failure is quite different and is reviewed elsewhere.

    The all-trans retinoic acid (ATRA) is the treatment of first line of acute promyelocytic leukemia (APL). ATRA is usually well tolerated, but a few major side effects can be observed, ATRA syndrome (RAS) being the most important of them, potentially fatal. The manifestations of this Syndrome are fever, weight gain, pulmonary infiltrates, pleural or pericardial effusions, hypotension, liver dysfunction and renal failure. We studied to the 29 patients diagnosed in (January of 2002 - December of 2004) of acute promyelocytic leukemia (APL), which were treated with ATRA, all received the 45 dose of mg/m(2)/d . The diagnosis of the leukemia was made by citomorphologist analysis. The criterion of renal insufficiency, it was an increase of the creatinina superior to 20% of the basal level. The definition of the transretinoico acid Syndrome was based on the clinical criteria of Frankel. Fourteen patients presented the Transretinoico Syndrome (48.3%), 11 of which (37.9%) died. The fundamental differences between the patients with or without ATRA were: fever (14 vs. 9, p=0,017), gain of weight (14 vs 0, p=0,000), pleural effusion (14 vs 2, p=0.000), pulmonary infiltrates (13 vs 1, p=0,000), cardiac failure (12 versus 2, p=0,000), respiratory distress (12 versus 4, p=0,003), presence of renal failure (10 vs 4, p=0,02), necessity of substitute renal treatment (6 vs 0, p=0,006) and arterial hypotension (12 vs. 3, p=0,001). The acute renal failure appeared in 10 of the 14 patients with SAR (71.4%), to 12+/-5 (1-25) days of the beginning of the treatment and their duration it was of 14+/-5 (1-46) days. Six (60%) needed substitute renal treatment and 5 (50%) died. Of the patients who survived, only a patient continues in dialysis. In both patient in that renal biopsy was made, the study showed signs of cortical necrosis. The appearance of acute renal failure in the course of the SAR is frequent, being observed deterioration of the renal function that needs substitute renal treatment

  1. Increased blood-brain transfer in a rabbit model of acute liver failure

    The blood-to-brain transfer of [ 14 C]alpha-aminoisobutyric acid was investigated by quantitative autoradiography in normal rabbits and rabbits with acute liver failure induced by the selective hepatotoxin galactosamine. The blood-to-brain transfer of alpha-aminoisobutyric acid was similar in control animals and animals 2 and 7 h after galactosamine injections, but was increased five- to tenfold in certain gray-matter areas of the brain in animals 11 and 18 h after galactosamine treatment. No detectable differences in white-matter uptake of [ 14 C]alpha-aminoisobutyric acid were found between the control and treated groups. The increase in alpha-aminoisobutyric acid transfer within the gray-matter areas suggested that a general or nonspecific increase in brain capillary permeability occurred in these areas. No clinical signs of early hepatic encephalopathy were observed in the treated rabbits, except for 1 animal from the 18-h postgalactosamine group. Thus, enhanced blood-brain transfer of alpha-aminoisobutyric acid preceded the development of overt hepatic encephalopathy. The distribution of radioactivity after the intravenous administration of [ 14 C]galactosamine showed that virtually none of the hepatotoxin localized in the brain, suggesting that the drug itself does not have a direct effect upon the blood-brain barrier or the brain. The increased uptake of alpha-aminoisobutyric acid at 11 and 18 h implies that the transfer of other solutes would also be enhanced, that central nervous system homeostasis would be compromised, and that the resulting changes in brain fluid composition could contribute to or cause hepatic encephalopathy

    Acute decompensated heart failure is a common emergency department presentation with significant associated morbidity and mortality. Heart failure accounts for more than 1 million hospitalizations annually, with a steadily increasing incidence as our population ages. This issue reviews recent literature regarding appropriate management of emergency department presentations of acute decompensated heart failure, with special attention to newer medication options. Emergency department management and appropriate interventions are discussed, along with critical decision-making points in resuscitation for both hypertensive and hypotensive patients.

    To investigate the changes in serotonin (5-HT) and noradrenaline (NA) in hepatic encephalopathy as a result of acute and chronic liver failure in rat. One hundred and ten Sprague-Dawley (SD) rats were randomly divided into groups of normal control (n=20), experimental group of acute liver failure (ALF) encephalopathy (n=45), and experimental group of chronic liver failure (CLF) encephalopathy (n=45). Two dosages of thioacetamide (TAA) of 500 mg/kg were gavaged with an interval of 24 hours to reproduce ALF model. To reproduce CLF model rats were fed with 0.03% TAA in drinking water for 10 weeks, and 50% of TAA dosage was added or withheld according to the change in weekly body weight measurement. Animals were sacrificed and venous blood specimens were obtained after successful replication of model, and 5-HT, NA, ammonia, parameters of liver function were determined, and liver and brain were studied pathologically. The experiment showed that the liver functions of rats in groups ALF encephalopathy and CLF encephalopathy deteriorated seriously, changes in alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), albumen (ALB), ALB/globulin (A/G), and blood ammonia were observed(Pliver and brain pathologies were identical to those of ALF and CLF encephalopathy. The values of 5-HT were increased in groups ALF encephalopathy and CLF encephalopathy [(16.06+/-1.08) micromol/L and (15.32+/-1.48) micromol/L] compared with the normal group [(2.75+/-0.26) micromol/L, both Pencephalopathy [(94.0+/-2.13) pmol/L vs.(121.2+/-14.8) pmol/L,Pencephalopathy and CLF encephalopathy. The content of NA decreases remarkably in CLF encephalopathy.

    This paper provides a practical clinical application of guideline recommendations relating to the inpatient monitoring of patients with acute heart failure, through the evaluation of various clinical, biomarker, imaging, invasive and non-invasive approaches. Comprehensive inpatient monitoring is crucial to the optimal management of acute heart failure patients. The European Society of Cardiology heart failure guidelines provide recommendations for the inpatient monitoring of acute heart failure, but the level of evidence underpinning most recommendations is limited. Many tools are available for the in-hospital monitoring of patients with acute heart failure, and each plays a role at various points throughout the patient's treatment course, including the emergency department, intensive care or coronary care unit, and the general ward. Clinical judgment is the preeminent factor guiding application of inpatient monitoring tools, as the various techniques have different patient population targets. When applied appropriately, these techniques enable decision making. However, there is limited evidence demonstrating that implementation of these tools improves patient outcome. Research priorities are identified to address these gaps in evidence. Future research initiatives should aim to identify the optimal in-hospital monitoring strategies that decrease morbidity and prolong survival in patients with acute heart failure. © 2018 The Authors.

    Although communication failures between professionals in acute care delivery occur, explanations for these failures remain unclear. We aim to gain a deeper understanding of interprofessional communication failures by assessing two different explanations for them. A multiple case study containing six cases (i.e. acute care chains) was carried out in which semi-structured interviews, physical artifacts and archival records were used for data collection. Data were entered into matrices and the pattern-matching technique was used to examine the two complementary propositions. Based on the level of standardization and integration present in the acute care chains, the six acute care chains could be divided into two categories of care processes, with the care chains equally distributed among the categories. Failures in communication occurred in both groups. Communication routines were embedded within organizations and descriptions of communication routines in the entire acute care chain could not be found. Based on the results, failures in communication could not exclusively be explained by literature on process typology. Literature on organizational routines was useful to explain the occurrence of communication failures in the acute care chains. Organizational routines can be seen as repetitive action patterns and play an important role in organizations, as most processes are carried out by means of routines. The results of this study imply that it is useful to further explore the role of organizational routines on interprofessional communication in acute care chains to develop a solution for failures in handover practices.

    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.

    In situ hybridization with oligonucleotide probes has been used to localise hepatitis A virus RNA genomic sequences in formalin-fixed and routinely processed human liver biopsies from three patients. Using radiolabelled Sulphur-35 antisense probes, viral genomic sequences were found in all three cases, but signal intensity was greatest in cases 1 and 2 with fulminant hepatitis, and was minimal in the third case of resolving hepatitis biopsied 2 months after acute illness. Localisation showed the viral RNA to be present in hepatocytes, sinusoidal cells and inflammatory cells in and around the portal tracts. Both cases showed signal in similar cell types, but the distribution of staining was predominantly periportal in case 1, whereas lobular staining was more apparent in case 2. Hybridization with sense polarity probes failed to detect any evidence of replicative intermediates of antigenomic viral RNA. The presence of hepatitis A RNA in phagocytic cells was confirmed using immunohistochemistryfor a macrophage marker, CD68, combined with in situ hybridization. In all cases the signal was predominantly cytoplasmic, and this was confirmed with the use of tritiated probes. (au).

    Full Text Available Adult seroprevalence of HAV is decreasing in developed countries including South Korea, due to general sanitation improvement. Although hepatitis A vaccination was introduced in South Korea more than 20 years ago, recent infection rates have not decreased. In this study, we investigate the seroprevalence of anti-HAV IgG, and estimate the national disease burden of acute hepatitis A in adult population.Seroprevalence data were collected from health promotion center of Korea University Guro Hospital, in Seoul, Korea from 2010 to 2014. Data from adults (≥20-years being tested for anti-HAV IgG were included. In addition, epidemiological and clinical data of patients diagnosed with acute hepatitis A from 2009 to 2013, were collected from Korean Statistical Information Service (KOSIS and the National Health Insurance Service (NHIS database. Data were stratified and compared by age groups.A total of 11,177 subjects were tested for anti-HAV IgG from 2010 to 2014. Age-related seroprevalence showed relatively low seropositivity in young adults. Incidence of acute hepatitis A was highest in 2009 and lowest in 2013. When categorized by age group, adults in their 20s and 30s had more HAV infections and related-admissions than older adults. However, ICU admission rate and average insurance-covered cost was high in older adults.The anti-HAV IgG seropositivity in Korean younger adult population was low while the incidence of acute hepatitis A was high, especially in the 20-39 aged. However, a substantial number of older adults were infected, and required more intensive procedures and incurred higher insurance-covered medical costs.

    Toluene, formerly known as toluol, is an aromatic hydrocarbon that is widely used as an industrial feedstock and as a solvent. Like other solvents, toluene is sometimes also used as an inhalant drug for its intoxicating properties. It has potential to cause multiple effects in the body including death. I report a case of a 27-year-old male, chronic spray paint sniffer, who presented with severe generalized muscle weakness and developed acute respiratory failure requiring ventilatory support. Toluene toxicity was confirmed with measurement of hippuric acid of 8.0 g/L (normal <5.0 g/L). Acute respiratory failure is a rare complication of chronic toluene exposure that may be lethal if it is not recognized immediately. To our knowledge, this is the second case of acute respiratory failure due to toluene exposure.

    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 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.

    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.

    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. © Georg Thieme Verlag KG Stuttgart · New York.

    Nutritional supplements are frequently considered to be harmless but indiscriminate use of unlabelled ingredients may lead to significant adverse reactions. In 2004, identification of four index cases of acute hepatitis associated with Herbalife intake led to a ministry of health investigation in all Israeli hospitals. Twelve patients with acute idiopathic liver injury in association with consumption of Herbalife products were investigated. Eleven of the patients were females, aged 49.5+/-13.4 y. One patient had stage I primary biliary cirrhosis and another had hepatitis B. Acute liver injury was diagnosed after 11.9+/-11.1 months of initiation of Herbalife consumption. Liver biopsies demonstrated active hepatitis, portal inflammation rich with eosinophils, ductular reaction and parenchymal inflammation with peri-central accentuation. One patient developed sub-fulminant and two fulminant episodes of hepatic failure. Hepatitis resolved in eleven patients, while one patient succumbed to complications following liver transplantation. Three patients resumed consumption of Herbalife products following normalization of liver enzymes, resulting in a second bout of hepatitis. An association between intake of Herbalife products and acute hepatitis was identified in Israel. We call for prospective evaluation of Herbalife products for possible hepatotoxicity. Until then, caution should be exercised by consumers, especially among individuals suffering from underlying liver disease.

    A 47-year-old man with a history of polyarticular gout was admitted to the nephrology service because of severe renal insufficiency (creatinine 6.25 mg/dl). Three days before admission he had a pain crisis in his knees and ankles and self-administered 20 x 1 mg granules of colchicine p.o. over a period of 4 - 5 hours together with six suppositories each containing 100 mg of indomethacin. The patient began vomiting within 24 hours, experienced diarrhea which persisted for three days and then came to the hospital. The patient reported oliguria during the preceding 24 hours. In hospital, attempts to correct water and electrolyte balance were initiated. The patient became stabilized hemo-dynamically, the diarrhea disappeared within 24 hours, diuresis resumed and the renal function progressively improved. Leukopenia and thrombopenia were diagnosed, the transaminases increased: AST = 79 U/l, ALT = 132 U/l on the eighth day after taking the colchicine. The serology for hepatitis A, B, C and HIV viruses was negative; the serology for CMV and VEB revealed a previous infection. After being discharged from hospital 11 days after admission, the patient presented with the following parameters: hematocrit 39%, leukocytes 5,920/microl (3 470 neutrophils), prothrombin time 13 seconds, urea 44 mg/dl, creatinine 1.29 mg/dl, AST 16 U/l and ALT 35 U/l. The patient mistakenly ingested 20 mg ofcolchicine p.o. (0.22 mg/kg). The intoxication was associated with gastroenterocolitis, dehydration and renal failure during the first three days after ingestion. The patient also developed leukopenia, thrombopenia and mild hepatocellular injury. Renal failure due to colchicine intoxication is due to various factors such as depletion of volume/hypotension, rhabdomyolysis and multiorgan failure. In this case, the hypovolemia was probably the fundamental cause of the acute renal insufficiency as demonstrated by the quick recovery after administering fluids. It is possible that indomethacin may have

    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.

    Severe acute hepatotoxicity is a well known complication following the ingestion of ecstasy (3,4-methylenedioxymethamphetamine [MDMA] ecstasy). Hepatic dysfunction has also been reported after acute cocaine intoxication. However, chronic hepatitis after prolonged use of ecstasy and/or cocaine has rarely been reported. We report the case of a 27-year-old woman hospitalized with edema, ascites and severe liver failure (prothrombin rate 33%), following the use of ecstasy and cocaine over the previous 9 months. Clinical, biological, radiological and pathology findings were recorded at admission and over 8 years' follow-up. Liver biopsy showed architectural distortion caused by bridging fibrosis, proliferation of cholangioles, and lesions of active interface hepatitis. Other causes of acute and chronic liver disease were excluded. Magnetic resonance imaging showed marked liver fibrosis. After withdrawal of both substances clinical examination and liver function tests progressively normalized. Long-term monitoring with magnetic resonance imaging showed progressive regression of fibrosis. Use of ecstasy and cocaine may cause chronic hepatitis leading to marked liver fibrosis, which may regress after withdrawal of both substances. Copyright © 2013 Elsevier Masson SAS.

    It is essential to accurately predict Postoperative liver failure (PHLF) which is a life-threatening complication. Liver hardness measurement (LSM) is widely used in non-invasive assessment of liver fibrosis. The aims of this study were to explore the application of preoperative liver stiffness measurements (LSM) by transient elastography in predicting postoperative liver failure (PHLF) in patients with hepatitis B related hepatocellular carcinoma. The study included 247 consecutive patients with hepatitis B related hepatocellular carcinoma who underwent hepatectomy between May 2015 and September 2015. Detailed preoperative examinations including LSM were performed before hepatectomy. The endpoint was the development of PHLF. All of the patients had chronic hepatitis B defined as the presence of hepatitis B surface antigen (HBsAg) for more than 6 months and 76 (30.8%) had cirrhosis. PHLF occurred in 37 (14.98%) patients. Preoperative LSM (odds ratio, OR, 1.21; 95% confidence interval, 95% CI: 1.13-1.29; P hepatocellular carcinoma.

    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.

    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. 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. 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%; psuccessful 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). 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.

    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 (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. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    Full Text Available Acute ethanol intoxication increases the production of reactive oxygen species (ROS. Hemorrhagic shock with subsequent resuscitation (H/R also induces ROS resulting in cellular and hepatic damage in vivo. We examined the role of acute ethanol intoxication upon oxidative stress and subsequent hepatic cell death after H/R. 14 h before H/R, rats were gavaged with single dose of ethanol or saline (5 g/kg, EtOH and ctrl; H/R_EtOH or H/R_ctrl, resp.. Then, rats were hemorrhaged to a mean arterial blood pressure of 30±2 mmHg for 60 min and resuscitated. Two control groups underwent surgical procedures without H/R (sham_ctrl and sham_EtOH, resp.. Liver tissues were harvested at 2, 24, and 72 h after resuscitation. EtOH-gavage induced histological picture of acute fatty liver. Hepatic oxidative (4-hydroxynonenal, 4-HNE and nitrosative (3-nitrotyrosine, 3-NT stress were significantly reduced in EtOH-gavaged rats compared to controls after H/R. Proapoptotic caspase-8 and Bax expressions were markedly diminished in EtOH-gavaged animals compared with controls 2 h after resuscitation. EtOH-gavage increased antiapoptotic Bcl-2 gene expression compared with controls 2 h after resuscitation. iNOS protein expression increased following H/R but was attenuated in EtOH-gavaged animals after H/R. Taken together, the data suggest that acute EtOH-gavage may attenuate H/R-induced oxidative stress thereby reducing cellular injury in rat liver.

    Full Text Available A patient with miliary tuberculosis and a chronic urogenital focus is described, who had a borderline renal function at diagnosis and developed overt renal failure upon daily treatment with rifampin (RMP, isoniazid (INH and ethambutol (EMB. This is the first Brazilian report of BMP induced renal damage. A renal biopsy taken on the third day of oliguria showed recent tubular necrosis with acute interstitial inflammation and granuloma formation. The aspect of the granulomatous lesion hightly suggested drug etiology because of the lack of palisading, high incidence of neutrophils and absence of facid-fast bacilli. This is the first presentation of an acute granulomatous interstitial nephritis probably due to RMP. Furthermore the pathogenesis of the renal damage caused by tuberculosis and RMP are discussed.

    Full Text Available The purpose of the research: to analyze insufficiency of medical care for patients with acute respiratory failure in the ICU.Materials and methods. It was a retrospective study of 160 patients' medical records (age from 15 to 84 years with acute respiratory failure (ARF hospitalized in the ICUs of 24 regional and municipal hospitals of the Irkutsk Oblast. Medical records were provided by the Territorial Fund of Compulsory Medical Insurance of citizens of Irkutsk region.The results. The basic defects in conducting mechanical ventilation were associated with improper lung function evaluation, microbiological tests of sputum and radiology. ARF was not diagnosed in 32 of 160 ICU patients (20%. In 23% of cases the causes of ARF were not diagnosed. The greatest part of the defects in the treatment of patients with acute respiratory failure was found during the treatment of hypoxemia: no recovery of the respiratory tract patency, no prescription of oxygen for hypoxemia, no mechanical ventilation for persistent hypoxemia on the background of maximum oxygen supply and late switching to mechanical ventilation at the stage of hypoxic cardiac arrest.Conclusions. The use of pulse oximetry alone in the absence of arterial blood gas analysis in 98% of patients with acute respiratory failure and failure to perform the lung X-ray and/or MSCT imaging in 21% of patients were accompanied by a high level of undiagnosed acute respiratory distress syndrome (78%, lung contusion (60%, pulmonary embolism (40%, cardiogenic pulmonary edema (33%, and nosocomial pneumonia (28%. Defects of treatment of patients with ARF in 46% of cases were caused by inadequate management of hypoxemia associated with the recovery of the respiratory tract patency, prescription of oxygen, and mechanical ventilation.

    Hepatitis B prevention in European Union/European Economic Area (EU/EEA) countries relies on vaccination programmes. We describe the epidemiology of acute hepatitis B virus (HBV) at country and EU/EEA level during 2006–2014. Using a multi-level mixed-effects Poisson regression model we assessed differences in the acute HBV infection notification rates between groups of countries that started universal HBV vaccination before/in vs after 1995; implemented or not a catch-up strategy; reached a vaccine coverage ≥ 95% vs  0.05) were found in the acute HBV infection notification rates between groups of countries, while as vaccine coverage increased, such rates decreased (p < 0.01). Countries with universal HBV vaccination before 1995, a catch-up strategy, and a vaccine coverage ≥ 95% had significant decreasing trends (p < 0.01). Ending HBV transmission in Europe by 2030 will require high vaccine coverage delivered through universal programmes, supported, where appropriate, by catch-up vaccination campaigns. PMID:29439751

    Aminotransferase levels do not always increase during acute hepatitis or during an acute flare-up of chronic hepatitis. Persistently increased levels of serum alpha-Fetoprotein in an adult with liver disease suggest not only the presence or progression of hepatocellular carcinoma or its recurrence after hepatic resection or after other therapeutic approaches such as chemotherapy or chemoembolization, but also it suggests that there is an acute exacerbation of hepatitis or liver cirrhosis. We report here on two unusual cases of HBV- & HCV-related liver cirrhosis with acute exacerbation of hepatitis in which there was an insignificant elevation of the aminotransferase levels, but there were markedly increased alpha-Fetoprotein levels observed. The levels of alpha-Fetoprotein decreased gradually in both cases since the beginning of antiviral therapy, which implies that the increased levels were due to aggravation of the accompanying hepatitis. These cases also emphasize that using only the measurement of alpha-Fetoprotein is not sufficient for the diagnosis of hepatocellular carcinoma, and that this diagnosis also requires a more specific measurement such as AFP L3 along with the standard imaging studies.

    Aim: To evaluate the early success of transarterial embolization (TAE) in patients with traumatic liver haemorrhage and to determine independent factors for its failure. Materials and methods: From January 2009 to December 2012, TAE was performed in 48 patients for traumatic liver haemorrhage. Their medical charts were reviewed for demographic information, pre-TAE vital signs and laboratory data, injury grade, type of contrast medium extravasation (CME) at CT, angiography findings, and early failure. “Early failure” was defined as the need for repeated TAE or a laparotomy for hepatic haemorrhage within 4 days after TAE. Variables were compared between the early success and early failure groups. Variables with univariate significance were also analysed using multivariate logistic regression for predictors of early failure. Results: Among 48 liver TAE cases, nine (18.8%) were early failures due to liver haemorrhage. Early failure was associated with injury grade (p = 0.039), major liver injury (grades 4 and 5; p = 0.007), multiple CMEs at angiography (p = 0.031), incomplete TAE (p = 0.002), and elevated heart rate (p = 0.026). Incomplete embolization (OR = 8; p = 0.042), and heart rate >110 beats/min (bpm; OR = 8; p = 0.05) were independent factors for early failure of TAE in the group with major liver injuries. Conclusion: Major hepatic injury is an important factor in early failure. Patients with a heart rate >110 bpm and incomplete embolization in the major injury group have an increased rate of early failure. The success rate of proximal TAE was comparable to that of the more time-consuming, superselective, distal TAE. - Highlights: • Early failure of TAE is associated with a higher grade of liver injury. • Incomplete embolization is more likely to suffer early failure of TAE. • A heart rate greater than 110 bpm is more likely to suffer early failure of TAE. • We recommend proximal embolization to prevent early failure of TAE

    Full Text Available Background/Aims Hepatic damage during transarterial chemoembolization (TACE is a critical complication in patients with hepatitis B virus (HBV-related hepatocellular carcinoma (HCC. Apart from its role in preventing HBV reactivation, there is some evidence for the benefits of preemptive antiviral therapy in TACE. This study evaluated the effect of preemptive antiviral therapy on acute hepatic deterioration following TACE. Methods This retrospective observational study included a prospectively collected cohort of 108 patients with HBV-related HCC who underwent TACE between January 2007 and January 2013. Acute hepatic deterioration following TACE was evaluated. Treatment-related hepatic decompensation was defined as newly developed encephalopathy, ascites, variceal bleeding, elevation of the bilirubin level, prolongation of prothrombin time, or elevation of the Child-Pugh score by ≥2 within 2 weeks following TACE. Univariate and multivariate analyses were conducted to identify factors influencing treatment-related decompensation. Preemptive antiviral therapy involves directing prophylaxis only toward high-risk chronic hepatitis B patients in an attempt to prevent the progression of liver disease. We regarded at least 6 months as a significant duration of preemptive antiviral treatment before diagnosis of HCC. Results Of the 108 patients, 30 (27.8% patients received preemptive antiviral therapy. Treatment-related decompensation was observed in 25 (23.1% patients during the follow-up period. Treatment-related decompensation following TACE was observed more frequently in the nonpreemptive group than in the preemptive group (29.5% vs. 6.7%, P=0.008. In the multivariate analysis, higher serum total bilirubin (Hazard ratio [HR] =3.425, P=0.013, hypoalbuminemia (HR=3.990, P=0.015, and absence of antiviral therapy (HR=7.597, P=0.006 were significantly associated with treatment-related hepatic decompensation. Conclusions Our findings suggest that

    Acute renal failure affects from 1% to 25% of patients admitted to intensive care units. These figures vary depending on the population studied and criteria. The complications of acute renal failure (fluid overload, metabolic acidosis, hyperkalemia, bleeding) are treated. However, mortality remains high despite the technological advances of recent years because acute renal failure is usually associated with sepsis, respiratory failure, serious injury, surgical complications or consumption coagulopathy. Mortality ranges from 30% to 90%. Although there is no universally accepted definition, the RIFLE classification gives us an operational tool to define the degree of acute renal failure and to standardize the initiation of renal replacement techniques as well as to evaluate the results. Therefore, nurses working within the intensive care unit must be familiar with this disease, with its treatment (drug or alternative) and with the prevention of possible complications. Equally, they must be capable of detecting the manifestations of dependency each one of the basic needs and to be able to identify the collaboration problems in order to achieve an individualized care plan.

  17. Necrostatin-1 protects against reactive oxygen species (ROS-induced hepatotoxicity in acetaminophen-induced acute liver failure

    Directory of Open Access Journals (Sweden)

    Kenji Takemoto

    2014-01-01

    Full Text Available Excessive acetaminophen (APAP use is one of the most common causes of acute liver failure. Various types of cell death in the damaged liver are linked to APAP-induced hepatotoxicity, and, of these, necrotic cell death of hepatocytes has been shown to be involved in disease pathogenesis. Until recently, necrosis was commonly considered to be a random and unregulated form of cell death; however, recent studies have identified a previously unknown form of programmed necrosis called receptor-interacting protein kinase (RIPK-dependent necrosis (or necroptosis, which is controlled by the kinases RIPK1 and RIPK3. Although RIPK-dependent necrosis has been implicated in a variety of disease states, including atherosclerosis, myocardial organ damage, stroke, ischemia–reperfusion injury, pancreatitis, and inflammatory bowel disease. However its involvement in APAP-induced hepatocyte necrosis remains elusive. Here, we showed that RIPK1 phosphorylation, which is a hallmark of RIPK-dependent necrosis, was induced by APAP, and the expression pattern of RIPK1 and RIPK3 in the liver overlapped with that of CYP2E1, whose activity around the central vein area has been demonstrated to be critical for the development of APAP-induced hepatic injury. Moreover, a RIPK1 inhibitor ameliorated APAP-induced hepatotoxicity in an animal model, which was underscored by significant suppression of the release of hepatic enzymes and cytokine expression levels. RIPK1 inhibition decreased reactive oxygen species levels produced in APAP-injured hepatocytes, whereas CYP2E1 expression and the depletion rate of total glutathione were unaffected. Of note, RIPK1 inhibition also conferred resistance to oxidative stress in hepatocytes. These data collectively demonstrated a RIPK-dependent necrotic mechanism operates in the APAP-injured liver and inhibition of this pathway may be beneficial for APAP-induced fulminant hepatic failure.

    To know the survival rate in patients with RIFLE I and II stages on acute renal failure, treated with supportive care or continuous renal replacement therapy with PRISMA machine, at an intensive care unit. There were included patients of both sexes, aged 16 to 69 years, with acute renal failure in RIFLE I and II stages and score of scale APACHE II lower than 36 points. The sample studied was divided in two groups: a group was treated with supportive care, and the other group received continuous renal replacement therapy via PRISMA machine. We compared mortality between both groups and the association with the RIFLE stages with Pearson's chi-squared test. The average score of the scale APACHE I was 14 points, and the probability of death was 15 %. The patients with acute renal failure RIFLE I were 54.5 % and RIFLE II 45.5 %, with mortality of 30.4 % and 38.8 %, respectively. Patients in RIFLE I stage who received supportive care and continuous replacement therapy had non-statistical differences in mortality (p = 0.356). The mortality in patients with acute renal failure in RIFLE II stage treated with continuous replacement therapy was higher (p = 0.000). Because of its accessibility and lower mortality, supportive care should be the initial procedure in patients with acute renal failure in RIFLE I and II stages.

    Hepatitis A virus is one of the most frequent causes of foodborne infection, which is closely associated with sanitary conditions and hygienic practices. The clinical spectrum of acute hepatitis A is wide, ranging from mild case without any noticeable symptoms to severe case with acute liver failure leading to mortality. The severity and outcome are highly correlated with age at infection. In developing countries, most people are infected in early childhood without significant symptom. Ironically, in area where sanitary condition has improved rapidly, adults who do not have immunity for viral hepatitis A (VH-A) in early childhood is accumulating. Adults without immunity are exposed to risks of symptomatic disease and large outbreaks in society. In Korea, where hygiene has improved rapidly, acute hepatitis A is a significant health burden that needs to be managed with nationwide health policy. The incidence of symptomatic VH-A has increased since 2000 and peaked in 2009. Korea has designated hepatitis A as a group 1 nationally notifiable infectious disease in 2001. Since 2001, mandatory surveillance system has been established to detect every single case of acute hepatitis A. Universal, nationwide vaccination program for newborns was introduced in 2015. In this review, we will present the current epidemiologic status of viral hepatitis A, and evaluate the effectiveness of the current nationwide strategies for the control of viral hepatitis A in Korea. Furthermore, we presented some action proposals that can help eliminate viral hepatitis A, which is a significant health burden in Korea.

    Full Text Available Abstract Background It is thought that a good survival rate of patients with acute liver failure can be achieved by establishing an artificial liver support system that reliably compensates liver function until the liver regenerates or a patient undergoes transplantation. We introduced a new artificial liver support system, on-line hemodiafiltration, in patients with acute liver failure. Methods This case series study was conducted from May 2001 to October 2008 at the medical intensive care unit of a tertiary care academic medical center. Seventeen consecutive patients who admitted to our hospital presenting with acute liver failure were treated with artificial liver support including daily on-line hemodiafiltration and plasma exchange. Results After 4.9 ± 0.7 (mean ± SD on-line hemodiafiltration sessions, 16 of 17 (94.1% patients completely recovered from hepatic encephalopathy and maintained consciousness for 16.4 ± 3.4 (7-55 days until discontinuation of artificial liver support (a total of 14.4 ± 2.6 [6-47] on-line hemodiafiltration sessions. Significant correlation was observed between the degree of encephalopathy and number of sessions of on-line HDF required for recovery of consciousness. Of the 16 patients who recovered consciousness, 7 fully recovered and returned to society with no cognitive sequelae, 3 died of complications of acute liver failure except brain edema, and the remaining 6 were candidates for liver transplantation; 2 of them received living-related liver transplantation but 4 died without transplantation after discontinuation of therapy. Conclusions On-line hemodiafiltration was effective in patients with acute liver failure, and consciousness was maintained for the duration of artificial liver support, even in those in whom it was considered that hepatic function was completely abolished.

Noninvasive positive pressure ventilation has expanded its role in the treatment of both chronic and acute respiratory failure. Its initial use in conditions such as obstructive sleep apnea, neuromuscular disease and tracheobronchomalacia, have been shown to improve quality of life and reduce mortality. Over the past 20 years studies have looked at using noninvasive ventilation in the management of acute respiratory failure from pulmonary edema, asthma and COPD exacerbations.

    Full Text Available Background and Aims. To investigate the association between serum albumin levels within 24 hrs of patient admission and the development of persistent organ failure in acute pancreatitis. Methods. A total of 700 patients with acute pancreatitis were enrolled. Multivariate logistic regression and subgroup analysis determined whether decreased albumin was independently associated with persistent organ failure and mortality. The diagnostic performance of serum albumin was evaluated by the area under Receiver Operating Characteristic (ROC curves. Results. As levels of serum albumin decrease, the risk of persistent organ failure significantly increases (Ptrend<0.001. The incidence of organ failure was 3.5%, 10.6%, and 41.6% in patients with normal albumin and mild and severe hypoalbuminaemia, respectively. Decreased albumin levels were also proportionally associated with prolonged hospital stay (Ptrend<0.001 and the risk of death (Ptrend<0.001. Multivariate analysis suggested that biliary etiology, chronic concomitant diseases, hematocrit, blood urea nitrogen, and the serum albumin level were independently associated with persistent organ failure. Blood urea nitrogen and the serum albumin level were also independently associated with mortality. The area under ROC curves of albumin for predicting organ failure and mortality were 0.78 and 0.87, respectively. Conclusion. A low serum albumin is independently associated with an increased risk of developing of persistent organ failure and death in acute pancreatitis. It may also be useful for the prediction of the severity of acute pancreatitis.

    Proenkephalin (pro-ENK) has emerged as a novel biomarker associated with both renal function and cardiac function. However, its clinical and prognostic value have not been well evaluated in symptomatic patients with heart failure. The association between pro-ENK and markers of renal function was evaluated in 95 patients with chronic heart failure who underwent renal hemodynamic measurements, including renal blood flow (RBF) and glomerular filtration rate (GFR) with the use of 131 I-Hippuran and 125 I-iothalamate clearances, respectively. The association between pro-ENK and clinical outcome in acute heart failure was assessed in another 1589 patients. Pro-ENK was strongly correlated with both RBF (P renal tubular markers. In the acute heart failure cohort, pro-ENK was a predictor of death through 180 days, heart failure rehospitalization through 60 days, and death or cardiovascular or renal rehospitalization through day 60 in univariable analyses, but its predictive value was lost in a multivariable model when other renal markers were entered in the model. In patients with chronic and acute heart failure, pro-ENK is strongly associated with glomerular function, but not with tubular damage. Pro-ENK provides limited prognostic information in patients with acute heart failure on top of established renal markers. Copyright © 2016 Elsevier Inc. All rights reserved.

    Alcoholic liver diseases often evolve to acute-on-chronic liver failure (ACLF), which increases the risk of (multi-)organ failure and death. We investigated the development and characteristics of alcohol-related ACLF and evaluated prognostic scores for prediction of mortality in Asian patients with active alcoholism. A total of 205 patients who were hospitalized with severe alcoholic liver disease were included in this retrospective cohort study, after excluding those with serious cardiovascular diseases, malignancy, or co-existing viral hepatitis. The Chronic Liver Failure (CLIF) Consortium Organ Failure score was used in the diagnosis and grading of ACLF, and the CLIF Consortium ACLF score (CLIF-C ACLFs) was used to predict mortality. Patients with ACLF had higher Maddrey discriminant function, model for end-stage liver disease (MELD), and MELD-sodium scores than those without ACLF. Infections were more frequently documented in patients with ACLF (33.3% vs 53.0%; P = 0.004). Predictive factors for ACLF development were systemic inflammatory response syndrome (odds ratio [OR], 2.239; P alcohol-related ACLF in Asian patients with active alcoholism. The CLIF-C ACLFs may be more useful for predicting mortality in ACLF cases than liver-specific scoring systems. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    The red blood cell distribution width (RDW) is increased in chronic liver disease, but its clinical significance in hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is still unclear. The aim of the present study was to investigate the clinical significance of RDW in HBV-ACLF patients. The medical records of HBV-ACLF patients who were admitted to The Second Affiliated Hospital of Anhui Medical University between April 2012 and December 2015 were retrospectively reviewed. Correlations between RDW, neutrophil lymphocyte ratio (NLR), and the model for end-stage liver disease (MELD) scores were analyzed using the Spearman's approach. Multivariable stepwise logistic regression test was used to evaluate independent clinical parameters predicting 3-month mortality of HBV-ACLF patients. The association between RDW and hospitalization outcome was estimated by receiver operating curve (ROC) analysis. Patient survival was estimated by Kaplan-Meier analysis and subsequently compared by log-rank test. Sixty-two HBV-ACLF patients and sixty CHB patients were enrolled. RDW were increased in HBVACLF patients and positively correlated with the NLR as well as MELD scores. Multivariate analysis demonstrated that RDW value was an independent predictor for mortality. RDW had an area under the ROC of 0.799 in predicting 3-month mortality of HBV-ACLF patients. Patients with HBV-ACLF who had RDW > 17% showed significantly poorer survival than those who had RDW ≤ 17%. RDW values are significantly increased in patients with HBV-ACLF. Moreover, RDW values are an independent predicting factor for an in-hospital mortality in patients with HBV-ACLF.

    Aloe is one of the leading products used in phytomedicine. Several cases of aloe-induced toxic hepatitis have been reported in recent years. However, its toxicology has not yet been systematically described in the literature. A 21-year-old female patient was admitted to our hospital with acute hepatitis after taking an aloe vera preparation for four weeks. Her history, clinical manifestation, laboratory findings, and histological findings all led to the diagnosis of aloe vera-induced toxic hepatitis. We report herein on a case of acute toxic hepatitis induced by aloe vera.

    Twelve patients with acute renal failure underwent L-dopa infusion into a renal artery and /sup 133/Xenon wash-out recordings before and during the infusion. Urine volume and sodium output were also compared during two 24 hours periods, before and after the procedure. Hemodynamic data were compared with data obtained from a matched group of patients receiving Furosemide (8 patients) in place of L-dopa. Only L-dopa infusion significantly increased outer cortical distribution. No blood flow change could be demonstrated in any component nor did the drug improve unitary excretion or the general course of the disease. Control data shows that reduced cortical distribution is the most consistent feature of acute renal failure, so that L-dopa does partially improve intrarenal hemodynamics in this condition. The failure of the drug to restore kidney function may be explained by the following reasons: inability of the agent to restore a normal wash-out pattern: involvment of non-hemodynamic factors, as suggested by comparing similar wash-out improvements after L-dopa in acute glomerulonephritis and in reversible acute renal failure.

    Hepatitis E virus (HEV) is endemic in Asian and African countries but is rarely reported in Western countries. Although there are some prominent neurological manifestations, HEV is rarely recognized by neurologists. This is a case report of myositis induced by HEV. We report the life-threatening case of a 57-year-old man with flaccid tetraparesis due to myositis, acute hepatitis, and renal failure caused by HEV infection. Muscle biopsy revealed scattered myofiber necrosis with a diffuse, mild lymphomonocytic infiltrate in the endomysium and perimysium. Because the patient suffered from an acute HEV infection with a rapidly progressive course of severe myopathy, we started ribavirin treatment. He recovered partially within 3 weeks and recovered fully within 6 months. This case highlights a neurological manifestation of endemic HEV infection with severe myositis in a patient with alcoholic chronic liver disease. Ribavirin treatment is effective in severe HEV infection and may also lead to rapid neurological recovery. © 2015 Wiley Periodicals, Inc.

    Objective noninvasive measures of dyspnea in patients with acute heart failure are lacking. In this review, we describe lung ultrasound as a tool to estimate the degree of pulmonary congestion in patients presenting with acute heart failure and to monitor therapeutic efficacy. Serial semiquantitative measures of sonographic B-lines in acute heart failure patients can be converted to pulmonary edema scores obtained at admission and hospital discharge. These scores provide prognostic information for short-term clinical outcomes. Lung ultrasound has the potential to measure changes in pulmonary edema during acute heart failure management and improve risk stratification. Copyright © 2016 Elsevier Inc. All rights reserved.

    Unlike the prolonged benefit produced by the treatment of chronic heart failure, newer drugs tested for the treatment of acute heart failure in the last decade have failed to provide evidence of clinical benefit beyond some improvement in symptom relief. In particular, no drug has shown the ability to reduce the higher medium- and long-term risk of morbidity and mortality in these patients after an episode of decompensation. Current understanding of the pathophysiology of acute heart failure and its consequences has led to the hypothesis that, beyond symptom control, effective therapies for this syndrome should target not only the hemodynamic changes of the initial phase of the syndrome but should also "protect" the organism from the activation of neurohumoral and inflammatory pathways triggered by the decompensation episode, which persist in time and confer a risk of deleterious effects in several organs and tissues. Serelaxin, a new drug related to the peptidic endogenous hormones of the relaxin family, has recently been shown to provide multiple beneficial effects in terms of "organ protection" - not only in the cardiovascular and renal systems - from these acute heart failure-related deleterious changes. This drug has already been tested in acute heart failure patients with encouraging results in terms of medium-term clinical benefit, rendering serelaxin as a serious candidate for first-line, prognosis-modifying therapy in this syndrome.

    Purpose: It is known that acute pancreatitis may cause secondary changes in several organs. Liver is one of these involved organs. In different experimental studies hepatic damages were shown histopathologically in acute pancreatitis but there are a few studies about perfusion disorders that accompany these histopathologic changes. Perfusion CT (pCT) provides the ability to detect regional and global alterations in organ blood flow. The purpose of the study was to describe hepatic perfusion changes in experimental acute pancreatitis model with pCT. Materials and methods: Forty Sprague-Dawley rats of both genders with average weights of 250 g were used. Rats were randomized into two groups. Twenty rats were in control group and 20 in acute pancreatitis group. pCT was performed. Perfusion maps were formed by processing the obtained images with perfusion CT software. Blood flow (BF) and blood volume (BV) values were obtained from these maps. All pancreatic and liver tissues were taken off with laparotomy and histopathologic investigation was performed. Student's t test was used for statistical analyses. Results: In pCT we found statistically significant increase in blood volume in both lobes of liver and in blood flow in right lobe of the liver (p < 0.01). Although blood flow in left lobe of the liver increased, it did not reach statistical significance. Conclusion: The quantitative analysis of liver parenchyma with pCT showed that acute pancreatitis causes a significant perfusion changes in the hepatic tissue. Systemic mediators seem to be effective as well as local inflammatory changes in perfusion changes.

    Objective: To evaluate the transplantation of autologous bone marrow stem cells via hepatic artery in treating acute hepatic injury in experimental rabbit models and to clarify the synergistic effect of hepatocyte growth-promoting factor (pHGF) in stem cell transplantation therapy for liver injury. Methods Acute hepatic injury models were established in 15 experimental rabbits by daily subcutaneous injection of CCl 4 olive oil solution with the dose of 0.8 ml/kg for 4 days in succession. The experimental rabbits were randomly and equally divided into three groups: study group A (stem cell transplant, n = 5), study group B (stem cell transplant + pFHG, n = 5), and control group (n = 5). Bone marrow of 5 ml was drawn from the tibia in all rabbits of both study groups, from which bone marrow stem cells were isolated by using density gradient centrifugation, and 5 ml cellular suspension was prepared. Under fluoroscopic guidance, catheterization through the femoral artery was performed and the cellular suspension was infused into the liver via the hepatic artery. Only injection of saline was carried out in the rabbits of control group. For the rabbits in group B, pFHG (2.0 mg/kg) was administered intravenously every other day for 20 days. At 2, 4 and 8 weeks after stem cell transplantation, hepatic function was determined. Eight weeks after the transplantation all the rabbits were sacrificed and the liver specimens were collected and sent for pathological examination. Results After stem cell transplantation, the hepatic function was gradually improved.Eight weeks after the transplantation, the activity of AST, ALT and the content of ALB, TBIL were significantly lower than that before the procedure, while the content of GOLB was markedly increased in all rabbits. In addition, the difference in the above parameters between three groups was statistically significant (P < 0.05). Pathologically, the hepatocyte degeneration and the fiberous hyperplasia in the study groups

    The prognostic significance of prior heart failure in acute coronary syndromes has not been well studied. Accordingly, we evaluated the baseline characteristics, management patterns and clinical outcomes in patients with acute coronary syndromes who had prior heart failure. The study population consisted of acute coronary syndrome patients in the Global Registry of Acute Coronary Events, expanded Global Registry of Acute Coronary Events and Canadian Registry of Acute Coronary Events between 1999 and 2008. Of the 13,937 eligible patients (mean age 66±13 years, 33% female and 28.3% with ST-elevation myocardial infarction), 1498 (10.7%) patients had a history of heart failure. Those with prior heart failure tended to be older, female and had lower systolic blood pressure, higher Killip class and creatinine on presentation. Prior heart failure was also associated with significantly worse left ventricular systolic function and lower rates of cardiac catheterization and coronary revascularization. The group with previous heart failure had significantly higher rates of acute decompensated heart failure, cardiogenic shock, myocardial (re)infarction and mortality in hospital. In multivariable analysis, prior heart failure remained an independent predictor of in-hospital mortality (odds ratio 1.48, 95% confidence interval 1.08-2.03, p=0.015). Prior heart failure was associated with high risk features on presentation and adverse outcomes including higher adjusted in-hospital mortality in acute coronary syndrome patients. However, acute coronary syndrome patients with prior heart failure were less likely to receive evidence-based therapies, suggesting potential opportunities to target more intensive treatment to improve their outcome. © The European Society of Cardiology 2015.

    Anorexia nervosa (AN) has the highest mortality rate of all psychiatric illnesses due to the widespread organ dysfunction caused by the underlying severe malnutrition. Starvation causes hepatocyte injury and death leading to a rise in aminotransferases. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases. Acute liver failure associated with coagulopathy and encephalopathy can rarely occur. Liver enzymes may also less commonly increase as part of the refeeding process due to hepatic steatosis and can be distinguished from starvation hepatitis by the finding of a fatty liver on ultrasonography. Individuals with AN and starvation-induced hepatitis are at increased risk of hypoglycemia due to depleted glycogen stores and impaired gluconeogenesis. Gastroenterology and hepatology consultations are often requested when patients with AN and signs of hepatitis are hospitalized. It should be noted that additional laboratory testing, imaging, or liver biopsy all have low diagnostic yield, are costly, and potentially invasive, therefore, not generally recommended for diagnostic purposes. While the hepatitis of AN can reach severe levels, a supervised increase in caloric intake and a return to a healthy body weight often quickly lead to normalization of elevated aminotransferases caused by starvation.

    Full Text Available Abstract Introduction An increase in circulating lymphocytes can be seen following infections such as infectious mononucleosis and pertussis, or in lymphoproliferative disorders such as acute and chronic lymphocytic leukemia. Acute lymphocytic crisis following herpes simplex virus hepatitis has not been described in the literature. Case presentation A 52-year-old man was admitted to our hospital reporting low-grade fever for the previous seven days, and fatigue. During the fifth day of hospitalization, the patient developed a lymphocytic crisis and, after further tests the patient was diagnosed as having herpes simplex virus hepatitis. Conclusion This case report shows that herpes simplex virus type 1 is a possible cause of an acute lymphocytic crisis similar to other well known infectious agents such as Epstein–Barr virus, cytomegalovirus, human immunodeficiency virus, human herpes virus type 6, adenovirus, toxoplasma and human T-cell lymphotropic virus. Furthermore, this case report expands the clinical spectrum of herpes simplex virus hepatitis, since it is reported in a nonimmunocompromised patient presenting with atypical acute lymphocytic syndrome.

    To assess differences in clinical outcomes of isolated renal failure (RF) compared to other forms of organ failure (OF) in patients with severe acute pancreatitis (SAP). Using a prospectively maintained database of patients with acute pancreatitis admitted to a tertiary medical center between 2003 and 2016, those with evidence of persistent OF were classified to renal, respiratory, cardiovascular, or multi-organ (2 or more organs). Data regarding demographics, comorbidities, etiology of acute pancreatitis, and clinical outcomes were prospectively recorded. Differences in clinical outcomes after development of isolated RF in comparison to other forms of OF were determined using independent t and Mann-Whitney U tests for continues variables, and χ 2 test for discrete variables. Among 500 patients with acute pancreatitis, 111 patients developed persistent OF: mean age was 54 years, and 75 (67.6%) were male. Forty-three patients had isolated OF: 17 (15.3%) renal, 25 (21.6%) respiratory, and 1 (0.9%) patient with cardiovascular failure. No differences in demographics, etiology of acute pancreatitis, systemic inflammatory response syndrome scores, or development of pancreatic necrosis were seen between patients with isolated RF vs isolated respiratory failure. Patients with isolated RF were less likely to require nutritional support (76.5% vs 96%, P = 0.001), ICU admission (58.8% vs 100%, P = 0.001), and had shorter mean ICU stay (2.4 d vs 15.7 d, P pancreatitis.

    A 81-year-old male was referred to our emergency outpatient unit due to acute renal failure. The level of serum creatinine was 276 μmol/l. A CT scan showed bilateral hydronephroureter, large bladder stone (7 cm × 6 cm × 6 cm) and bladder wall thickness. He was diagnosed as post renal failure due to bilateral hydronephroureter. Large bladder stone is thought to be the cause of bilateral hydronephroureter and renal failure. To improve renal failure, we performed open cystolithotomy and urethral catheterization. Three days after the surgery, the level of serum creatinine decreased to 224 μmol/l. He was discharged from our hospital with uneventful course. Bladder calculus is thought to be a rare cause of renal failure. We summarize the characteristics of bladder calculus causing renal failure. We should keep that long-term pyuria and urinary symptom, and repeated urinary tract infection can cause huge bladder calculus and renal failure in mind.

  7. Cerebral hemodynamic and metabolic changes in fulminant hepatic failure

    Directory of Open Access Journals (Sweden)

    Fernando Mendes Paschoal Junior

    Full Text Available ABSTRACT Intracranial hypertension and brain swelling are a major cause of morbidity and mortality of patients suffering from fulminant hepatic failure (FHF. The pathogenesis of these complications has been investigated in man, in experimental models and in isolated cell systems. Currently, the mechanism underlying cerebral edema and intracranial hypertension in the presence of FHF is multi-factorial in etiology and only partially understood. The aim of this paper is to review the pathophysiology of cerebral hemodynamic and metabolism changes in FHF in order to improve understanding of intracranial dynamics complication in FHF.

    To compare the epidemiologic profiles of hepatitis A virus (HAV) and hepatitis E virus (HEV) infections in Japan, the prevalence of clinical or subclinical HAV and HEV infections was investigated serologically and molecularly among 128 consecutive patients (age, mean +/- standard deviation, 37.5 +/- 14.7 years) who contracted acute hepatitis between 1989 and 2005 in a city hospital, and among 416 hemodialysis patients (60.1 +/- 12.6 years) and 266 medical staff members (34.6 +/- 11.4 years) at the same hospital, using stored periodic serum samples collected since the start of hemodialysis or employment, respectively. Between 1989 and 1995, among 93 patients with acute hepatitis, 51 (54.8%) were diagnosed with hepatitis A and only one patient with hepatitis E. Between 1996 and 2005, however, among 35 patients, only 3 (8.6%) were diagnosed with hepatitis A and 2 (5.7%) with hepatitis E. Although subclinical HEV infection was recognized in four hemodialysis patients (one each in 1979, 1980, 1988, and 2003) and two medical staff members (1978 and 2003) in previous studies, none of the 191 hemodialysis patients who had been negative for anti-HAV at the start of hemodialysis contracted HAV infection during the observation period of 7.6 +/- 6.4 years. Only one (0.4%) of the 246 medical staff members who had been negative for anti-HAV at the start of employment acquired hepatitis A during the observation period of 7.9 +/- 8.0 years: none had subclinical HAV infection. Clinical or subclinical HEV infection has occurred rarely during the last three decades, while HAV infection has markedly decreased at least since 1996. 2006 Wiley-Liss, Inc.

    The interaction between acute heart failure (AHF) and renal dysfunction is complex. Several studies have evaluated the prognostic value of this syndrome. The aim of this systematic review, which includes non-selected samples, was to investigate the impact of different renal function variables on the AHF prognosis. The categories included in the studies reviewed included: creatinine, blood urea nitrogen (BUN), the BUN/creatinine quotient, chronic kidney disease, the formula to estimate the glomerular filtration rate, criteria of acute renal injury and new biomarkers of renal damage such as neutrophil gelatinase-associated lipocalin (NGAL and cystatin c). The basal alterations of the renal function, as well as the acute alterations, transient or not, are related to a worse prognosis in AHF, it is therefore necessary to always have baseline, acute and evolutive renal function parameters.

    Objective: To assess the outcome and risk factors associated with mortality in patients with acute respiratory failure (ARF). Design: Observational study. Place and Duration of Study: The Aga Khan University Hospital, Karachi, between January 1997 and June 2001. Patients and Methods: All adult patients admitted with a medical cause of acute respiratory failure were reviewed. The primary outcome measure was mortality and secondary outcome measures were factors associated with mortality in ARF. Multiple logistic regression analysis was used to identify the independent risk factors for mortality. Results: A total of 270 patients were admitted with ARF. Hypercapnic respiratory failure was seen in 186 (69%) and hypoxemic in 84 (31%) cases. Pneumonia and COPD exacerbation were the most common underlying causes of ARF. Ventilator support was required in 93 (34.4%) patients. Hospital mortality was 28%. Chronic renal failure, malignancy, hypokalemia, severe acidosis (pH <7.25), septicemia and ARDS independently correlated with mortality. Mortality rate increased sharply (84%) with the presence of three or more risk factors. Conclusion: Acute respiratory failure has a high mortality rate (28%). Development of ARDS or septicemia was associated with high mortality. Presence of more than one risk factor significantly increased the mortality rate. (author)

    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.

  15. 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 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.

    Twenty-four survivors of acute, nonobstructive, nonnephritic renal failure had a renal scan using iodohippurate sodium I 131 performed early in the acute illness. Scans were judged according to whether the renal images were prominent, faint, or absent during the first 30 minutes after intravenous injection of 100 to 250 microcuries of iodohippurate sodium I 131. All ten patients with prominent renal images attained life-sustaining renal function with an average postrecovery creatinine clearance of 80 ml/min. Of the seven patients with faint renal images, six recovered life-sustaining renal function (average creatinine clearance of 39 ml/min), and one required chronic hemodialysis. Seven patients had no renal image initially; four recovered life-sustaining renal function with an average creatinine clearance of 25 ml/min; three required chronic hemodialysis. We conclude that, for patients with acute renal failure, the appearance of the renal image obtained using this substance is an important indicator of renal viability and of the likelihood for functional recovery

    Acute decompensated heart failure (ADHF) is a common illness presenting to the emergency department (ED) that is amenable to observation unit (OU) treatment. As the number of baby boomers continues to grow and the incidence of heart failure increases, the financial implications of ADHF treatment will become more prominent. Obtaining institutional support and developing a good working relationship with cardiology colleagues is vital to creating workable ADHF protocols for whichever type of OU an institution decides to use.

    Tumor necrosis factor-α antagonists (anti-TNF-α) have been associated with drug-induced liver injury. However, cases of anti-TNF-α-associated acute liver failure have only been rarely reported. To identify cases of anti-TNF-α-associated acute liver failure and evaluate patterns of liver injury and common characteristics to the cases. The United States Acute Liver Failure Study Group database was searched from 1998 to 2014. Four subjects were identified. A PubMed search for articles that reported anti-TNF-α-associated acute liver failure identified five additional cases. The majority of individuals affected were female (eight of nine cases). Age of individual ranged from 20 to 53 years. The most common anti-TNF-α agent associated with acute liver failure was infliximab (n = 8). The latency between initial drug exposure and acute liver failure ranged from 3 days to over a year. Of the nine cases, six required emergency LT. Liver biopsy was obtained in seven cases with a preponderance toward cholestatic-hepatitic features; none showed clear autoimmune features. Anti-TNF-α-associated acute liver failure displays somewhat different characteristics compared with anti-TNF-α-induced drug-induced liver injury. Infliximab was implicated in the majority of cases. Cholestatic-hepatitic features were frequently found on pre-transplant and explant histology.

    Full Text Available Serologic diagnosis is one of the most widely used diagnostic methods for Q fever, but the window period in antibody response of 2 to 3 weeks after symptom onset results in significant diagnostic delay. We investigated the diagnostic utility of Q fever PCR from formalin-fixed liver tissues in Q fever patients with acute hepatitis.We reviewed the clinical and laboratory data in patients with Q fever hepatitis who underwent liver biopsy during a 17-year period, and whose biopsied tissues were available. We also selected patients who revealed granuloma in liver biopsy and with no Q fever diagnosis within the last 3 years as control. Acute Q fever hepatitis was diagnosed if two or more of the following clinical, serologic, or histopathologic criteria were met: (1 an infectious hepatitis-like clinical feature such as fever (≥ 38°C with elevated hepatic transaminase levels; (2 exhibition of a phase II immunoglobulin G (IgG antibodies titer by IFA of ≥ 1:128 in single determination, or a four-fold or greater rise between two separate samples obtained two or more weeks apart; (3 histologic finding of biopsy tissue showing characteristic fibrin ring granuloma.A total of 11 patients with acute Q fever hepatitis were selected and analyzed. Of the 11 patients, 3 (27% had exposure to zoonotic risk factors and 7 (63% met the serologic criteria. Granulomas with either circumferential or radiating fibrin deposition were observed in 10 cases on liver biopsy and in 1 case on bone marrow biopsy. 8 (73% revealed positive Coxiella burnetii PCR from their formalin-fixed liver tissues. In contrast, none of 10 patients with alternative diagnosis who had hepatic granuloma revealed positive C. burnetii PCR from their formalin-fixed liver tissues.Q fever PCR from formalin-fixed liver tissues appears to be a useful adjunct for diagnosing Q fever hepatitis.

    Acute renal failure (ARF) is a syndrome characterised by rapid decline in glomerular filtration rate and retention of nitrogenous waste products such as urea and creatinine. The objective of this study was to study the prevalence, risk and outcome of women with obstetrical renal failure. Methods: This observational study was conducted in Department of Obstetrics and Gynaecology, Liaquat University Hospital, Hyderabad, Pakistan from October 2009 to September 2010. Thirty-five patients with obstetrical acute renal failure were included in the study, patients with chronic renal diseases, hypertension, diabetes mellitus and renal stones were excluded from the study. A detailed history was followed by thorough examination and investigation. Their clinical history, physical examination and intake/urine output was recorded. Routine laboratory investigations were done related to each case and specialised investigations like renal scan, renal ultrasonography and renal biopsies were performed in selected cases where recovery was delayed for more than 3 weeks. Results: Total numbers of admissions in obstetric ward were 3,285. Pregnancy related acute renal failure was found in 35 (1.065%) women. Age ranged from 18-40 years. Most of the women belonged to age group 30-35. Out of 35 women 31.42% had postpartum haemorrhage. Ante partum haemorrhage was found in 25.71%, Eclampsia in 17.14%, DIC in 14.28%, and sepsis in 11.42%. Anuria was observed in 25 patients, remaining presented with oliguria (28.57%). Haemodialysis was done in 75% of patients, others were managed conservatively. Complete recovery was observed in 53% cases. Maternal mortality was 25.71% and foetal mortality was 22.85%. Conclusion: Pregnancy related ARF is one of the most common causes of ARF, it is a dangerous complication of pregnancy which carries very high mortality and morbidity. (author)

    2016-01-01

    Full Text Available Intrahepatic cholestasis of pregnancy (ICP is a complication of pregnancy resulting in elevation of serum bile acid levels. ICP is often associated with underlying liver disease, including hepatitis C. Bile acids in relationship to the acute infection of hepatitis C virus have not yet been delineated in the literature. A 26-year-old gravida 4 para 2103 with dichorionic, diamniotic twin gestation and history of intravenous drug abuse developed ICP in the setting of acute hepatitis C infection. In addition to clinical symptoms of pruritus and right upper quadrant pain, she developed severe elevation in bile acids, 239 micromol/L, and transaminitis aspartate aminotransferase 1033 U/L, and alanine aminotransferase 448 U/L. She received ursodeoxycholic acid and antenatal testing was performed. Patient delivered vaginally at 33-week gestation following preterm rupture of membranes. Neonates were admitted to NICU and had uncomplicated neonatal courses. In the setting of ICP with significant transaminitis and severe elevation of bile acids, consideration of acute viral hepatitis is important, especially considering the worsening opioid epidemic and concurrent increase in intravenous drug use in the United States. Further study is needed regarding the acute form of HCV infection and its effect on ICP and associated bile acids.

    The liver is frequently involved by amyloidosis, but hyperbilirubinemia and liver failure are uncommon features. A mild elevation of the serum alkaline phosphatase value and, less frequently, hepatomegaly are the most common findings. Usually the patients have no symptoms related with the liver involvement; the clinical manifestation and the long term prognosis depends on the renal and cardiac disease. We report an unusual clinical presentation of primary amyloidosis in a previously asymptomatic 65 years old woman who was admitted to the hospital because of ictericia and ascitis mimicking a drug induced acute hepatic failure.

    Severe liver injury result in development of hepatic encephalopathy (HE) and often also in brain edema that is a potentially fatal complication. HE and brain edema are correlated to the level and persistence of hyperammonemia and the presence of systemic inflammation. Treatment of HE and brain...... edema is based on restoring and keeping normal physiological variables including tonicity, blood gasses, lactate, temperature and vascular resistance by a wide variety of interventions. In addition liver support devices improve the stage of HE, cerebral metabolic rate for oxygen and glucose......, and are used either as a bridge to liver transplantation or liver recovery in patients with fulminant hepatic failure and in patients with acute-on-chronic liver failure. This short review will mainly focus on the management and efficacy of doing plasma exchange on HE in patients with acute HE....

    To compares the clinical features of patients infected with hepatitis E virus (HEV) with or without severe jaundice. In addition, the risk factors for HEV infection with severe jaundice were investigated. We enrolled 235 patients with HEV into a cross-sectional study using multi-stage sampling to select the study group. Patients with possible acute hepatitis E showing elevated liver enzyme levels were screened for HEV infection using serologic and molecular tools.HEV infection was documented by HEV antibodies and by the detection of HEV-RNA in serum. We used χ(2) analysis, Fisher's exact test, and Student's t test where appropriate in this study. Significant predictors in the univariate analysis were then included in a forward, stepwise multiple logistic regression model. No significant differences in symptoms, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, or hepatitis B virus surface antigen between the two groups were observed. HEV infected patients with severe jaundice had significantly lower peak serum levels of γ-glutamyl-transpeptidase (GGT) (median: 170.31 U/L vs 237.96 U/L, P = 0.007), significantly lower ALB levels (33.84 g/L vs 36.89 g/L, P = 0.000), significantly lower acetylcholine esterase (CHE) levels (4500.93 U/L vs 5815.28 U/L, P = 0.000) and significantly higher total bile acid (TBA) levels (275.56 μmol/L vs 147.03 μmol/L, P = 0.000) than those without severe jaundice. The median of the lowest point time tended to be lower in patients with severe jaundice (81.64% vs 96.12%, P = 0.000). HEV infected patients with severe jaundice had a significantly higher viral load (median: 134 vs 112, P = 0.025) than those without severe jaundice. HEV infected patients with severe jaundice showed a trend toward longer median hospital stay (38.17 d vs 18.36 d, P = 0.073). Multivariate logistic regression indicated that there were significant differences in age, sex, viral load, GGT, albumin, TBA, CHE, prothrombin index, alcohol

    2015-05-01

    Cardiorenal syndrome has been defined as the simultaneous dysfunction of both the heart and the kidney. Worsening renal function that occurs in patients with acute heart failure has been classified as cardiorenal syndrome type 1. In this setting, worsening renal function is a common finding and is due to complex, multifactorial, and not fully understood processes involving hemodynamic (renal arterial hypoperfusion and renal venous congestion) and nonhemodynamic factors. Traditionally, worsening renal function has been associated with worse outcomes, but recent findings have revealed mixed and heterogeneous results, perhaps suggesting that the same phenotype represents a diversity of pathophysiological and clinical situations. Interpreting the magnitude and chronology of renal changes together with baseline renal function, fluid overload status, and clinical response to therapy might help clinicians to unravel the clinical meaning of renal function changes that occur during an episode of heart failure decompensation. In this article, we critically review the contemporary evidence on the pathophysiology and clinical aspects of worsening renal function in acute heart failure.

    A total of 142 women with severe acute renal failure (ARF) resulting from obstetric causes was treated by dialysis at a single centre from 1956 to 1987. One-year survival was 78.6%, which compares favourably with other causes of ARF. Abortion, haemorrhage and preclampsia comprised 95% of cases, with survival being best (82.9%) with abortion. Survival was adversely affected by increasing age. Acute cortical necrosis (12.7% of patients) carried 100% mortality after 6 years. Follow-up of survivors showed normal renal function up to 31 years following ARF; 25-year patient survival was 71.6%. Improvements in obstetric care and the disappearance of illegal abortions have resulted in a dramatic decline in the incidence of obstetric ARF.

    The majority of heart failure hospitalizations in the United States originate in the emergency department (ED). Current strategies for acute heart failure syndromes have largely been tailored after chronic heart failure guidelines and care. Prospective ED-based acute heart failure syndrome trials are lacking, and current guidelines for disposition are based on either little or no evidence. As a result, the majority of ED acute heart failure syndrome patients are admitted to the hospital. Recent registry data suggest there is a significant amount of heterogeneity in acute heart failure syndrome ED presentations, and diagnostics and therapeutics may need to be individualized to the urgency of the presentation, underlying pathophysiology, and acute hemodynamic characteristics. A paradigm shift is necessary in acute heart failure syndrome guidelines and research: prospective trials need to focus on diagnostic, therapeutic, and risk-stratification algorithms that rely on readily available ED data, focusing on outcomes more proximate to the ED visit (5 days). Intermediate outcomes (30 days) are more dependent on inpatient and outpatient care and patient behavior than ED management decisions. Without these changes, the burden of acute heart failure syndrome care is unlikely to change. This article proposes such a paradigm shift in acute heart failure syndrome care and discusses areas of further research that are necessary to promote this change in approach.

    Objective: To determine the spectrum of pathological lesions in percutaneous renal biopsies of patients with acute renal failure (ARF) and to compare our findings with reported literature. Results: A total of 158 patients were studied. Of these 57 were males and 101 females. Mean age of the patients in this series were 30.7 years with a range of 6 to 75 years. Of these 61 (38.6%) had acute tubular necrosis, 36 (22.7%) acute cortical necrosis and 49(31%) patients had various types of glomerculonephriits (GN). Eight patients (5%) had acute tubulointerstitial nephritis, 3(1.8%) acute pyelonephritis and one patient had mucormycosis. Conclusion: This study showed that even in the selected population of biopsied ARF cases, there was a high prevalence of ischemic renal disease. A substantial number of cases in unexplained ARF on renal biopsy were due to various forms of glomerulonephritis. (author)

    In conscious, chronically instrumented rats we examined 1) renal tubular functional changes involved in lipopolysaccharide (LPS)-induced acute renal failure; 2) the effects of LPS on the expression of selected renal tubular water and sodium transporters; and 3) effects of milrinone......-alpha and lactate, inhibited the LPS-induced tachycardia, and exacerbated the acute LPS-induced fall in GFR. Furthermore, Ro-20-1724-treated rats were unable to maintain MAP. We conclude 1) PDE3 or PDE4 inhibition exacerbates LPS-induced renal failure in conscious rats; and 2) LPS treated rats develop an escape......, a phosphodiesterase type 3 (PDE3) inhibitor, and Ro-20-1724, a PDE4 inhibitor, on LPS-induced changes in renal function. Intravenous infusion of LPS (4 mg/kg b.wt. over 1 h) caused an immediate decrease in glomerular filtration rate (GFR) and proximal tubular outflow without changes in mean arterial pressure (MAP...

    In acute liver failure (ALF), urea production is severely impaired, and detoxification of ammonia by glutamine synthesis plays an important protective role. The aim of this study was to examine the effects of therapeutic high-volume plasmapheresis (HVP) on arterial concentrations and splanchnic exchange rates of ammonia, urea, and amino acids-in particular, glutamine. A quantity of 8 L of plasma was exchanged over the course of 7 h in 11 patients with ALF after development of hepatic encephalopathy grade III-IV. Splanchnic exchange rates of ammonia, urea, and amino acids were measured by use of liver vein catheterization. HVP removed ammonia and glutamine at a rate of 1 micromol/min and 27 micromol/min, respectively. Arterial ammonia decreased from 160 +/- 65 to 114 +/- 50 micromol/L (p HVP) were as follows: for ammonia, -93 +/- 101 versus -70 +/- 80 micromol/min (NS); urea-nitrogen, 0.08 +/- 1.64 versus -0.31 +/- 0.45 mmol/min (NS); alanine, -73 +/- 151 versus 12 +/- 83 micromol/min (p HVP in patients with ALF. The data suggest that this effect of HVP could be explained by increased hepatic urea synthesis and possibly by increased glutamine synthesis in muscle tissue.

    Abnormalities in liver function tests appear in 3% of pregnancies. Severe acute liver damage can be an exclusive condition of pregnancy (dependent or independent of pre-eclampsia) or a concomitant disease. HELLP syndrome and acute fatty liver of pregnancy are the most severe liver diseases associated with pregnancy. Both appear during the third trimester and have a similar clinical presentation. Acute fatty liver may be associated with hypoglycemia and HELLP syndrome is closely linked with pre-eclampsia. Among concomitant conditions, fulminant acute hepatitis caused by medications or virus is the most severe disease. Its clinical presentation may be hyper-acute with neurological involvement and severe coagulation disorders. It has a high mortality and patients should be transplanted. Fulminant hepatic failure caused by acetaminophen overdose can be managed with n-acetyl cysteine. Because of the high fetal mortality rate, the gestational age at diagnosis is crucial.

    A large number of xenobiotics are reported to be potentially hepatotoxic. Free radicals generated from the xenobiotic metabolism can induce lesions of the liver and react with the basic cellular constituents - proteins, lipids, RNA and DNA. Hepatoprotective activity of aqueous ethanol extract of Zingiber officinale was evaluated against single dose of acetaminophen-induced (3g/kg, p.o.) acute hepatotoxicity in rat. Aqueous extract of Z. officinale significantly protected the hepatotoxicity as evident from the activities of serum transaminase and alkaline phosphatase (ALP). Serum glutamate pyruvate transaminase (SGPT), serum glutamate oxaloacetate transaminase (SGOT) and ALP activities were significantly (pHepatic lipid peroxidation was enhanced significantly (pofficinale (200 and 400mg/kg, p.o.) prior to acetaminophen significantly declines the activities of serum transaminases and ALP. Further the hepatic antioxidant status was enhanced in the Z. officinale plus acetaminophen treated group than the control group. The results of the present study concluded that the hepatoprotective effect of aqueous ethanol extract of Z. officinale against acetaminophen-induced acute toxicity is mediated either by preventing the decline of hepatic antioxidant status or due to its direct radical scavenging capacity.

    2004-08-01

    Hepatitis A virus (a picornavirus) and hepatitis E virus (so far unclassified) are small, non-enveloped and relatively stable RNA viruses with many similar, yet, not identical characteristics. Both viruses are transmitted preferentially by the fecal-oral route. Consequently, their spread is favoured by poor personal hygiene and inappropriate sanitary conditions. Infection can pass subclinically, take an acute and self limiting course, and can also manifest as fulminant hepatitis with liver failure. True chronic disease is unknown. Laboratory diagnosis is preferentially performed by serology, but can also be complemented by assay for viral RNA in stool or serum. Resolution of infection leads to immunity which, in the case of hepatitis A, is known to be fully protective and most likely lifelong. Available hepatitis A vaccines are able to induce a similar state of protection. Vaccines for hepatitis E are under development. Specific antiviral treatment is not yet available, neither for hepatitis A nor for hepatitis E.

    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.

    Unlike chronic heart failure (HF), the treatment for acute HF has not changed over the last decade. The drugs employed have shown their ability to control symptoms but have not achieved organ protection or managed to reduce medium to long-term morbidity and mortality. Advances in our understanding of the pathophysiology of acute HF suggest that treatment should be directed not only towards correcting the haemodynamic disorders and achieving symptomatic relief but also towards preventing organ damage, thereby counteracting myocardial remodelling and cardiac and extracardiac disorders. Compounds that exert vasodilatory and anti-inflammatory action in the acute phase of HF and can stop cell death, thereby boosting repair mechanisms, could have an essential role in organ protection.

    Full Text Available Ajaya Kumar Dhakal, Arati Shakya, Devendra Shrestha, Subhash Chandra Shah, Henish Shakya Department of Pediatrics, KIST Medical College Teaching Hospital, Imadol, Lalitpur, Nepal Abstract: Hepatitis A virus infection is a common public health problem in developing countries primarily due to poor hygiene and sanitation. The clinical features of hepatitis A virus are mostly related to the derangement of liver function with occasional extrahepatic complications. Herein, a 2.5-year-old girl presented with abdominal pain and decreased appetite for 4 days, high-colored urine for 3 days, and yellowish discoloration of the eyes for 2 days. On presentation, there was icterus along with hepatomegaly and diminished breath sounds on the right side were noted 1 day after admission. Chest X-ray revealed right sided pleural effusion; however, ultrasonography of chest and abdomen displayed bilateral pleural effusion (right more than left and minimal ascites with thickened gall bladder wall. Immunoglobulin M anti-hepatitis-A virus serology was positive. The pleural effusion in this child resolved spontaneously in 10 days. We report this case to highlight that hepatitis A infection should be considered in the differential diagnosis of pleural effusion in a patient with features of acute hepatitis. However, other common causes of pleural effusion such as tuberculosis and parapneumonic effusions that may coexist with hepatitis, especially in developing world, need to be excluded.

    Hepatic encephalopathy (HE) is a neuropsychiatric syndrome that ultimately occurs as a complication of acute or chronic liver failure; accompanied by hyperammonemia. This study aimed to evaluate the potential of biopropolis as a hepato- and neuro-protective agent using thioacetamide (TAA)-induced acute HE in rats as a model. Sixty Wistar rats were divided into 5 groups: Group 1 (normal control) received only saline and paraffin oil. Group 2 (hepatotoxic control) received TAA (300 mg/kg, once). Groups 3, 4, and 5 received TAA followed by vitamin E (100 mg/kg) and biopropolis (100 and 200 mg/kg), respectively, daily for 30 days. Evidences of HE were clearly detected in TAA-hepatotoxic group including significant elevation in the serum level of ammonia, liver functions, increased oxidative stress in liver and brain, apoptotic DNA fragmentation and overexpression of iNOS gene in brain tissue. The findings for groups administered biopropolis, highlighted its efficacy as a hepato- and neuro-protectant through improving the liver functions, oxidative status and DNA fragmentation as well as suppressing the brain expression of iNOS gene. In conclusion, biopropolis, at a dose of 200 mg/kg per day protected against TAA-induced HE through its antioxidant and antiapoptotic influence; therefore, it can be used as a protective natural product.

    Hepatitis E virus (HEV) causes a common infection in developing countries. HEV infection occurs as outbreaks, as sporadic clinical cases and as large epidemics in endemic areas. The objective of this study was to determine the presence of HEV infection in patients with clinical suspicion of hepatitis A virus (HAV) infection, referred to the Instituto Nacional de Higiene "Rafael Rangel" in Venezuela. Seventy-four sera were tested for anti-HAV and anti-HEV IgM antibodies. HEV-RNA was amplified from anti-HEV IgM positive sera using nested reverse transcription polymerase chain reaction for ORF1 (RNA dependent RNA polymerase region) and the amplicons sequenced for phylogenetic analysis. The frequency of anti-HEV IgM was 22/74 (30%) in the samples tested. Dual infection with HAV and HEV was found in 31% (12/39) of anti-HAV IgM positive patients. Viremia was detected in 3/22 (14%) of sera positive for anti-HEV IgM. Two HEV strains were classified as genotype 1 and one as genotype 3, which were closely related to Yam 67 (north of India) and US1 isolates from the USA, respectively. These findings suggest that HEV is an important cause of acute viral hepatitis in Venezuela as a single infection or co-infection with HAV, with high morbidity in children and young adults suggesting that this infection is endemic in Venezuela.

    Patients with Cushing's syndrome and excess exogenous glucocorticoids have an increased risk for venous thromboembolism, as well as arterial thrombi. The patients are at high risk of thromboembolic events, especially during active disease and even in cases of remission and after surgery in Cushing's syndrome and withdrawal state in glucocorticoid users. We present a case of Cushing's syndrome caused by adrenocorticotropic hormone-secreting lung carcinoid tumor. Our patient developed acute mesenteric ischemia after video-assisted thoracoscopic surgery despite administration of sufficient glucocorticoid and thromboprophylaxis in the perioperative period. In addition, our patient developed hepatic infarction after surgical resection of the intestine. Then, the patient was supported by total parenteral nutrition. Our case report highlights the risk of microthrombi, which occurred in our patient after treatment of ectopic Cushing's syndrome. Guidelines on thromboprophylaxis and/or antiplatelet therapy for Cushing's syndrome are acutely needed. The present case showed acute mesenteric thromboembolism and hepatic infarction after treatment of ectopic Cushing's syndrome.Patients with Cushing's syndrome are at increased risk for thromboembolic events and increased morbidity and mortality.An increase in thromboembolic risk has been observed during active disease, even in cases of remission and postoperatively in Cushing's syndrome.Thromboprophylaxis and antiplatelet therapy should be considered in treatment of glucocorticoid excess or glucocorticoid withdrawal.

    Full Text Available Sea drowning is a common cause of accidental death worldwide. Respiratory complications such as acute pulmonary oedema, which is often complicated by acute respiratory distress syndrome, is often seen. Noninvasive ventilation is already widely used as a first approach to treat acute respiratory failure resulting from multiple diseases. We report a case of a 45 year old man with a history of epilepsy, motor and mental handicap who developed acute respiratory failure secondary to sea water drowning after an epileptic crisis. We illustrate successful and rapid management of this case with noninvasive ventilation. We emphasize the advantages and limitations of using noninvasive ventilation to treat acute respiratory failure due to sea water drowning syndrome.

    Full Text Available Aim: to review the role of ursodeoxycholic acid in acute viral hepatitis. Methods: following literature searching according to the clinical question on Pubmed and Cochrane Library. After filtered with our inclusion and exclusion criteria, one meta-analysis and two randomized clinical trials are obtained. Through critical appraisal, it was concluded that the articles meet the criteria for validity and relevance. Results: the article found that there is a positive effect of ursodeoxycholic acid on the activity of serum transaminases and cholestasis indexes. However, there is insufficient evidence to support or to refute effects of  ursodeoxycholic acid on disease’s course as well as the viral load. Conclusion: better method of clinical trials are needed to obtain a valid and applicable result for daily practice. Key words: ursodeoxycholic acid, acute viral hepatitis

    Acute pancreatitis (AP) in patients with fulminant viral hepatitis is well recognized and its mortality depends on the severity of hepatitis rather than pancreatitis. Acute pancreatitis associated with non-fulminant acute hepatitis A (AHA) has been rarely described, and is considered to have a benign course with good response to conservative management. To perform a systematic review of the frequency and prognosis of AP associated with fulminant or non-fulminant AHA. An increasing number of reports describe AP associated with AHA. Some life-threatening complications related to AP may occur, and death has been reported. In addition, it is possible that early diagnosis of these cases may help in reducing the morbidity and mortality. Ovid Medline In-Process & Other Non-Indexed Citations, Ovid MEDLINE, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, Scopus, Google Scholar, and reference lists of relevant articles. All available studies discussing AP associated with fulminant or non-fulminant AHA. Two blinded independent observers extracted and assessed the frequency of AP associated with AHA based on large studies including all cases of AHA observed during a prolonged period of time, diagnosis of AHA based on anti-HAV IgM, diagnosis of fulminant hepatitis (FH) based on the American Association for the study of Liver Diseases (AASLD) position paper, diagnosis of AP based on the American College of Gastroenterology (ACG) guidelines, diagnosis of AP associated with AHA based on Makharia's association, and diagnosis of AP severity based on the Revision of the Atlanta Classification (RAC). We have developed a tool for risk of bias assessment of case reports and case-series and applied it to the included studies. The frequency of reported AP associated with AHA is 0-0.1%. Thirty-eight publications with a total of 54 patients meeting the inclusion criteria have been published. Twenty-two studies had a low risk

    Full Text Available Mirashini Swaminathan,1 Mark Alexander Ellul,2 Timothy JS Cross1 1Department of Gastroenterology, Royal Liverpool University Hospital, 2Faculty of Health and Life Sciences, Institute of Infection and Global Health, University of Liverpool, Liverpool, UK Abstract: Hepatic encephalopathy (HE is a common complication of liver dysfunction, including acute liver failure and liver cirrhosis. HE presents as a spectrum of neuropsychiatric symptoms ranging from subtle fluctuating cognitive impairment to coma. It is a significant contributor of morbidity in patients with liver disease. HE is observed in acute liver failure, liver bypass procedures, for example, shunt surgery and transjugular intrahepatic portosystemic shunt, and cirrhosis. These are classified as Type A, B and C HE, respectively. HE can also be classified according to whether its presence is overt or covert. The pathogenesis is linked with ammonia and glutamine production, and treatment is based on mechanisms to reduce the formation and/or removal of these compounds. There is no specific diagnostic test for HE, and diagnosis is based on clinical suspicion, excluding other causes and use of clinical tests that may support its diagnosis. Many tests are used in trials and experimentally, but have not yet gained universal acceptance. This review focuses on the definitions, pathogenesis and treatment of HE. Consideration will be given to existing treatment, including avoidance of precipitating factors and novel therapies such as prebiotics, probiotics, antibiotics, laxatives, branched-chain amino acids, shunt embolization and the importance of considering liver transplant in appropriate cases.

    Full Text Available 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.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.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.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.

    Full Text Available Hepatic encephalopathy describes the array of neurological alterations that occur during acute liver failure or chronic liver injury. While key players in the pathogenesis of hepatic encephalopathy, such as increases in brain ammonia, alterations in neurosteroid levels, and neuroinflammation, have been identified, there is still a paucity in our knowledge of the precise pathogenic mechanism. This review gives a brief overview of our understanding of the pathogenesis of hepatic encephalopathy and then summarizes the significant recent advances made in clinical and basic research contributing to our understanding, diagnosis, and possible treatment of hepatic encephalopathy. A literature search using the PubMed database was conducted in May 2017 using “hepatic encephalopathy” as a keyword, and selected manuscripts were limited to those research articles published since May 2014. While the authors acknowledge that many significant advances have been made in the understanding of hepatic encephalopathy prior to May 2014, we have limited the scope of this review to the previous three years only.

    There are limited data on the epidemiology of acute respiratory failure necessitating mechanical ventilation in patients with severe chronic obstructive pulmonary disease (COPD). The prognosis of acute respiratory failure requiring invasive mechanical ventilation is believed to be grim in this population. The purpose of this study was to illustrate the epidemiologic characteristics and outcomes of patients with underlying severe COPD requiring mechanical ventilation.A retrospective study of patients admitted to a quaternary referral medical intensive care unit (ICU) between January 2008 and December 2012 with a diagnosis of severe COPD and requiring invasive mechanical ventilation for acute respiratory failure.We evaluated 670 patients with an established diagnosis of severe COPD requiring mechanical ventilation for acute respiratory failure of whom 47% were male with a mean age of 63.7 ± 12.4 years and Acute physiology and chronic health evaluation (APACHE) III score of 76.3 ± 27.2. Only seventy-nine (12%) were admitted with a COPD exacerbation, 27(4%) had acute respiratory distress syndrome (ARDS), 78 (12%) had pneumonia, 78 (12%) had sepsis, and 312 (47%) had other causes of respiratory failure, including pulmonary embolism, pneumothorax, etc. Eighteen percent of the patients received a trial of noninvasive positive pressure ventilation. The median duration of mechanical ventilation was 3 days (interquartile range IQR 2-7); the median duration for ICU length of stay (LOS) was 5 (IQR 2-9) days and the median duration of hospital LOS was 12 (IQR 7-22) days. The overall ICU mortality was 25%. Patients with COPD exacerbation had a shorter median duration of mechanical ventilation (2 vs 4 days; P = .04), ICU (3 vs 5 days; P = .01), and hospital stay (10 vs 13 days; P = .01). The ICU mortality (9% vs 27%; P respiratory failure. A 1-unit increase in the APACHE III score was associated with a 1% decrease and having an active cancer was associated

    Prognostic markers of acute liver failure (ALF) are based on clinical, laboratory or radiological parameters. Most of the biochemical markers are based on hepatic degeneration. We studied the impact of serial serum alpha-fetoprotein (AFP) levels, a marker of liver regeneration, on the outcome of the patients with ALF. AFP levels were estimated on days 1 and 3 of hospitalisation of 32 patients with ALF and the ratio (AFP day3/day1) was calculated. All subjects were categorised as group A (expired) or group B (survived). The AFP ratio was 0.84  +  0.15 in group A (n = 20) versus 1.55  +  0.70 in group B (n = 10); P < 0.001. However, the absolute initial AFP values were not associated with the outcome, favourable or unfavourable. We conclude that AFP levels change dynamically during ALF and have the potential to be used as a predictor of outcome in isolation or in combination with well-established prognostic markers.

    Both viral and host factors are thought to influence the pathogenesis of hepatitis C virus (HCV) infection. We studied strain HC-TN (genotype 1a), which caused fulminant hepatic failure in a patient and, subsequently, severe hepatitis in a chimpanzee (CH1422), to analyze the relationship between...... persistently infected. CH1579 and CH1581, despite their differing outcomes, both developed significant intrahepatic cellular immune responses, but not antibodies to the envelope glycoproteins or neutralizing antibodies, during the acute infection.

    Full Text Available Hepatic encephalopathy (HE is a common complication of liver failure that is associated with poor prognosis. However, the prognosis is not uniform and depends on the underlying liver disease. Acute liver failure is an uncommon cause of HE that carries bad prognosis but is potentially reversible. There are several prognostic systems that have been specifically developed for selecting patients for liver transplantation. In patients with cirrhosis the prognosis of the episode of HE is usually dictated by the underlying precipitating factor. Acute-on-chronic liver failure is the most severe form of decompensation of cirrhosis, the prognosis depends on the number of associated organ failures. Patients with cirrhosis that have experienced an episode of HE should be considered candidates for liver transplant. The selection depends on the underlying liver function assessed by the Model for End-stage Liver Disease (MELD index. There is a subgroup that exhibits low MELD and recurrent HE, usually due to the coexistence of large portosystemic shunts. The recurrence of HE is more common in patients that develop progressive deterioration of liver function and hyponatremia. The bouts of HE may cause sequels that have been shown to persist after liver transplant.

    2013-06-01

    Renal failure secondary to acetaminophen poisoning is rare and occurs in approximately 1-2 % of patients with acetaminophen overdose. The pathophysiology is still being debated, and renal acetaminophen toxicity consists of acute tubular necrosis, without complication if treated promptly. Renal involvement can sometimes occur without prior liver disease, and early renal manifestations usually occur between the 2nd and 7th day after the acute acetaminophen poisoning. While therapy is exclusively symptomatic, sometimes serious metabolic complications can be observed. The monitoring of renal function should therefore be considered as an integral part of the management of children with acute, severe acetaminophen intoxication. We report 3 cases of adolescents who presented with acute renal failure as a result of voluntary drug intoxication with acetaminophen. One of these 3 girls developed severe renal injury without elevated hepatic transaminases. None of the 3 girls' renal function required hemodialysis, but one of the 3 patients had metabolic complications after her acetaminophen poisoning. Copyright © 2013 Elsevier Masson SAS.

    Traumatic and nontraumatic rhabdomyolysis can lead to acute renal failure (ARF), and acute alcohol intoxication can lead to multiple abnormalities of the renal tubules. We examined the effect of acute alcohol intoxication in a rat model of rhabdomyolysis and ARF. Intravenous injections of 5 g/kg ethanol were given to rats over 3 h, followed by glycerol-induced rhabdomyolysis. Biochemical parameters, including blood urea nitrogen (BUN), creatinine (Cre), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and creatine phosphokinase (CPK), were measured before and after induction of rhabdomyolysis. Renal tissue injury score, renal tubular cell expression of E-cadherin, nuclear factor-κB (NF-κB), and inducible nitric oxide synthase (iNOS) were determined. Relative to rats in the vehicle group, rats in the glycerol-induced rhabdomyolysis group had significantly increased serum levels of BUN, Cre, GOT, GPT, and CPK, elevated renal tissue injury scores, increased expression of NF-κB and iNOS, and decreased expression of E-cadherin. Ethanol exacerbated all of these pathological responses. Our results suggest that acute alcohol intoxication exacerbates rhabdomyolysis-induced ARF through its pro-oxidant and inflammatory effects.

    Technetium-99m pyrophosphate (Tc-PYP) imaging was performed in five patients with acute renal failure associated with nontraumatic rhabdomyolysis. Four patients had phencyclidine intoxication and one had viral pneumonia. During the acute phase, marked uptake of pyrophosphate was seen in all patients in several muscle groups, but always in the thigh adductors. The results show that phencyclidine intoxication can result in diffuse muscle uptake of Tc-PYP without overt evidence of muscle injury. Tc-PYP imaging may provide a clue to the cause of acute renal failure in patients with suspected rhabdomyolysis in whom elevations of serum creatine phosphokinase concentrations are equivocal.

    This study investigated annual medical costs using real-world data focusing on acute heart failure. The data were retrospectively collected from six tertiary hospitals in South Korea. Overall, 330 patients who were hospitalized for acute heart failure between January 2011 and July 2012 were selected. Data were collected on their follow-up medical visits for 1 year, including medical costs incurred toward treatment. Those who died within the observational period or who had no records of follow-up visits were excluded. Annual per patient medical costs were estimated according to the type of medical services, and factors contributing to the costs using Gamma Generalized Linear Models (GLM) with log link were analyzed. On average, total annual medical costs for each patient were USD 6,199 (±9,675), with hospitalization accounting for 95% of the total expenses. Hospitalization cost USD 5,904 (±9,666) per patient. Those who are re-admitted have 88.5% higher medical expenditure than those who have not been re-admitted in 1 year, and patients using intensive care units have 19.6% higher expenditure than those who do not. When the number of hospital days increased by 1 day, medical expenses increased by 6.7%. Outpatient drug costs were not included. There is a possibility that medical expenses for AHF may have been under-estimated. It was found that hospitalization resulted in substantial costs for treatment of heart failure in South Korea, especially in patients with an acute heart failure event. Prevention strategies and appropriate management programs that would reduce both frequency of hospitalization and length of stay for patients with the underlying risk of heart failure are needed.

  6. Autoimmune hepatitis in children.

    Mieli-Vergani, Giorgina; Vergani, Diego

    2002-08-01

    AIH, ASC, and de novo AIH after liver transplantation are childhood liver diseases of an autoimmune nature. The mode of presentation of AIH in childhood is variable, and the disease should be suspected and excluded in all children presenting with symptoms and signs of prolonged or severe acute liver disease. Although corticosteroids are effective in all types of childhood AIH, patients with LKM1 have a higher frequency of acute hepatic failure and relapse after corticosteroid withdrawal than do patients with ANA/SMA. ASC occurs commonly in the absence of inflammatory bowel disease, requires cholangiography for diagnosis, and improves during corticosteroid therapy. The development of AIH de novo in children who undergo liver transplantation for nonautoimmune liver disease may reflect interference with the maturation of T cells by immunosuppressive drugs.

    Acute hepatic failure (AHF) is a severe liver injury leading to sustained damage and complications. Induced pluripotent stem cells (iPSCs) may be an alternative option for the treatment of AHF. In this study, we reprogrammed human dental pulp-derived fibroblasts into iPSCs, which exhibited pluripotency and the capacity to differentiate into tridermal lineages, including hepatocyte-like cells (iPSC-Heps). These iPSC-Heps resembled human embryonic stem cell-derived hepatocyte-like cells in gene signature and hepatic markers/functions. To improve iPSC-Heps engraftment, we next developed an injectable carboxymethyl-hexanoyl chitosan hydrogel (CHC) with sustained hepatocyte growth factor (HGF) release (HGF-CHC) and investigated the hepatoprotective activity of HGF-CHC-delivered iPSC-Heps in vitro and in an immunocompromised AHF mouse model induced by thioacetamide (TAA). Intrahepatic delivery of HGF-CHC-iPSC-Heps reduced the TAA-induced hepatic necrotic area and rescued liver function and recipient viability. Compared with PBS-delivered iPSC-Heps, the HGF-CHC-delivered iPSC-Heps exhibited higher antioxidant and antiapoptotic activities that reduced hepatic necrotic area. Importantly, these HGF-CHC-mediated responses could be abolished by administering anti-HGF neutralizing antibodies. In conclusion, our findings demonstrated that HGF mediated the enhancement of iPSC-Hep antioxidant/antiapoptotic capacities and hepatoprotection and that HGF-CHC is as an excellent vehicle for iPSC-Hep engraftment in iPSC-based therapy against AHF.

    Acute liver failure (ALF) is a severe condition in which liver function rapidly deteriorates in individuals without prior history of liver disease. While most cases result from acetaminophen overdose or viral hepatitis, in up to a third of patients, no clear cause can be identified. Liver transplantation has greatly reduced mortality among these patients, but 40% of patients recover without liver transplantation. Therefore, there is an urgent need for rapid determination of the etiology of acute liver failure. In this case report, we present a case of herpes simplex 2 virus- (HSV-) associated ALF in an immunocompetent patient. The patient recovered without LT, but the presence of HSV was not suspected at the time, precluding more effective treatment with acyclovir. To determine the etiology, stored blood samples were analyzed using whole transcriptome shotgun sequencing followed by mapping to a panel of viral reference sequences. The presence of HSV-DNA in blood samples at the time of admission was confirmed using real-time polymerase chain reaction, and, at the time of discharge, HSV-DNA levels had decreased by a factor of 10 6 . Conclusions. In ALF cases of undetermined etiology, uncommon causes should be considered, especially those for which an effective treatment is available.

    This study was designed to investigate physicochemical characterization of the oil extracted from foxtail millet bran (FMBO), and the antioxidant and hepatoprotective effects against acute ethanol-induced hepatic injury in mice. GC-MS analysis revealed that unsaturated fatty acids (UFAs) account for 83.76% of the total fatty acids; in particular, the linoleic acid (C18:2) is the predominant polyunsaturated fatty acid (PUFA), and the compounds of squalene and six phytosterols (or phytostanols) were identified in unsaponifiable matter of FMBO. The antioxidant activity examination of FMBO in vitro showed highly ferric-reducing antioxidant power and scavenging effects against DPPH· and HO· radicals. Furthermore, the protective effect of FMBO against acute hepatic injuries induced by ethanol was verified in mice. In this, intragastric administration with different dosages of FMBO in mice ahead of acute ethanol administration could observably antagonize the ethanol-induced increases in serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), and the hepatic malondialdehyde (MDA) levels, respectively, along with enhanced hepatic superoxide dismutase (SOD) levels relative to the control. Hepatic histological changes were also observed and confirmed that FMBO is capable of attenuating ethanol-induced hepatic injury.

    Twenty-three MR studies of 19 patients with acute viral hepatitis were reviewed. The findings of MR imaging including peripotal high intensity (PHI) on T 2 -weighted images and gallbladder wall thickening (GBWT) were compared with the level of serum GOT level and clinical phase which was determined by the interval between the peak of serum GOT level and MR study. PHI was found in 15 out of 23 studies (65%) and GBWT in 7 out of 22 studies (32%). The incidence of these findings were correlated well with the severity of serum GOT level and clinical phase. PHI became less prominent gradually as during the clinical recovery. While GBWT was found in the earlier phase and disappeared immediately. PHI seems to correspond to edema and infiltration of inflammatory cells in the periportal area of the liver. (author)

    Epstein-Barr virus (EBV) is the causative agent of infectious mononucleosis (IM) which is characterized by the triad of fever, sore throat, and lymphadenopathy. Self-limited, mild liver function test abnormalities are seen in IM. Acute hepatitis in primary EBV infection is uncommon. Serum transaminases are elevated but are less than fivefold the normal levels in most cases and rarely exceed 10 times the normal levels in primary EBV infections especially in elderly. Laboratory diagnosis of acute EBV infection is by serological assays confirming the presence of EBV viral capsid antigen (VCA) IgM antibodies. Due to antigenic cross-reactivity with Herpes viruses, serological assays lack specificity; hence specific molecular diagnostic methods are required for confirmation of the etiology. The present report describes two cases of acute hepatitis caused by infection with EBV which had indistinguishable clinical features and biochemical markers from acute hepatitis caused by hepatotropic viruses such as hepatitis viruses A-E. The diagnosis of infection by EBV was confirmed by detection of EBV DNA in blood of both the patients and EBV DNA in the liver tissue of one of the patients. Copyright © 2013 Wiley Periodicals, Inc.

    Acute and acute hematogenous prosthetic joint infections (PJIs) are often treated with open debridement and polyethylene exchange (ODPE) in an effort to save the prosthesis, decrease morbidity, and reduce costs. However, failure of ODPE may compromise a subsequent 2-stage treatment. The purpose of this study is to identify patient factors that impact the success of ODPE for acute and acute hematogenous PJIs. A retrospective review examined comorbidities, preoperative laboratory values, and patient history for patients with successful and failed ODPE treatment for acute perioperative or acute hematogenous periprosthetic hip or knee joint infections. Successful treatment was defined as retaining a well-fixed implant without the need for additional surgery for a minimum of 6-month follow-up with or without lifelong oral maintenance antibiotics. Fifty-three of 72 patients (73.6%) underwent successful ODPE. Of the 19 failures, 14 completed 2-stage revision with one subsequent known failure for recurrent infection. Patients with a Staphylococcus aureus infection were more likely to fail ODPE (48.3% vs 11.6%, P = .0012, odds ratio 7.1, 95% confidence interval 2.3-25.3). Patients with a preoperative hematocrit ≤32.1 were also more likely to fail ODPE (55% vs 16%, P = .0013, odds ratio 6.7, 95% confidence interval 2.2-22.4). When neither risk factor was present, 97.1% of PJIs were successfully treated with ODPE. S aureus infection and preoperative hematocrit ≤32.1 are independent risk factors for ODPE failure. ODPE is a safe alternative to 2-stage revision in patients without preoperative anemia and without S aureus infection. Two-thirds of patients with a failed ODPE were successfully treated with a 2-stage reimplantation. Copyright © 2018 Elsevier Inc. All rights reserved.

    Regorafenib has been approved for treatment of patients with unresectable or recurrent gastrointestinal stromal tumors resistant to imatinib or sunitinib. However, regorafenib has severe side-effects, including acute liver failure. We describe the case of a patient with multiple liver metastases of a small intestinal stromal tumor who experienced acute liver failure while being treated with regorafenib. A 50-year-old patient with an unresectable small intestinal stromal tumor resistant to prior treatment with imatinib and sunitinib was started on regorafenib, but experienced acute liver failure 10 days later. Plasma exchange and steroid pulse treatment improved her liver function. During liver failure, abdominal ultrasonography showed to-and-fro flow in the portal vein. Lactate dehydrogenase concentration was markedly elevated to 1633 U/l. These findings indicate that liver failure in this patient was due to impaired liver blood flow. Regorafenib may impair liver blood flow, inducing acute liver failure. Copyright© 2015 International Institute of Anticancer Research (Dr. John G. Delinassios), All rights reserved.

    Acute-on-chronic liver failure (ACLF) is the most common type of liver failure and associated with grave consequences. Systemic inflammation has been linked to its pathogenesis and outcome, but the identifiable triggers are absent. Recently, extracellular histones, especially H4, have been recognized as important mediators of cell damage in various inflammatory conditions. This study aimed to investigate whether extracellular histones have clinical implications in patients with hepatitis B virus (HBV)-related ACLF. One hundred and twelve patients with HBV-related ACLF, 90 patients with chronic hepatitis B, 88 patients with HBV-related liver cirrhosis and 40 healthy volunteers were entered into this study. Plasma histone H4 levels, cytokine profile and clinical data were obtained. Besides, patient's sera were incubated overnight with human L02 hepatocytes or monocytic U937 cells in the presence or absence of antihistone H4 antibody, and cellular damage and cytokine production were evaluated. We found that plasma histone H4 levels were greatly increased in patients with ACLF as compared with chronic hepatitis B, liver cirrhosis and healthy control subjects and were significantly associated with disease severity, systemic inflammation and outcome. Notably, ACLF patients' sera incubation decreased cultured L02 cell integrity and induced profound cytokine production in the supernatant of U937 cells. Antihistone H4 antibody treatment abrogated these adverse effects, thus confirming a cause-effect relationship between extracellular histones and organ injury/dysfunction. The data support the hypothesis that the increased extracellular histone levels in ACLF patients may aggravate disease severity by inducing cellular injury and systemic inflammation. Histone-targeted therapies may have potentially interventional value in clinical practice. © 2016 John Wiley & Sons Ltd.

    Autoimmune hepatitis (AIH) is a severe life-threatening hepatopathy of unknown etiology, affecting both pediatric and adult populations, and characterised by inflammatory liver histology, circulating non-organ-specific autoantibodies, and hypergammaglobulinaemia. AIH is a very heterogeneous disease with a variety of clinical presentations, ranging from asymptomatic liver test abnormalities to acute severe hepatitis or even acute liver failure. It responds very well to immunosuppressive treatment with prednisolone with or without azathioprine. Patients who are intolerant or fail to respond to standard therapy are candidates for alternative immunosuppressive regimens, the combination of steroids with mycophenolate mofetil or calcineurin inhibitors being the most frequently reported. The pathogenesis of AIH remains not completely understood, although there is evidence that genetic predisposition, molecular mimicry and defective immunoregulatory mechanisms contribute to the autoimmune liver damage. A literature search was conducted using the key-words 'autoimmune hepatitis', 'immunogenetics', 'regulatory T-cells' and 'immunosuppression'. The aim of this review is to discuss recent breakthroughs in the understanding AIH pathogenesis, diagnosis and treatment. Expert commentary: Progress in the understanding of AIH pathogenesis is likely to contribute to the development of novel therapeutic strategies, such as the adoptive transfer of autologous expanded antigen-specific regulatory T-cells.

    Full Text Available Introduction. Viral hepatitis is one of the global challenges for modern medicine. Among them, hepatitis B (GB remains one of the most widespread viral diseases of the present day. According to the WHO estimates, more than 1/3 of the world's population (2 billion people has serological evidence of current or transmitted HBV infection, of which 350 million are chronically infected. Separate studies have identified the state of the colon biocenosis in patients with acute hepatitis and found that dysbiotic lesions of varying degrees are found in patients with viral hepatitis in 73.3% - 96% of cases [6-8]. Disturbances of the quantitative and qualitative composition of the microflora reduce the detoxification function of the intestine and increase the toxic load on the liver, which, in turn, negatively affects the development of the basic pathological process. The aim of the work was to determine the degree of dysbiotic changes in the microflora of the large intestine and to evaluate the effectiveness of their correction with a symbiotic drug in patients with acute hepatitis B. Materials and methods. To perform the task, 108 patients with acute hepatitis B, aged 18-69 being on hospital treatment at Kharkiv Regional Clinical Hospital of Infectious Diseases, have been examined. The diagnosis has been set on the basis of clinical anamnestic, epidemiological, laboratory and instrumental data. The etiological verification of the diagnosis has been performed by detecting specific serological markers of hepatitis B (HBsAg, HBeAg, anti-HBc IgM, by the ELISA method. The diagnosis of GHB and its clinical and pathogenetic variants of the course, form and degree of severity have been determined according to the International Statistical Classification of Diseases and Related Security Problems Health (ICD-10, version 2006. According to the purpose of study the patients have been divided into groups as follows: group A - the main one, where patients have

    Parvovirus B19 infection can present with myriads of clinical diseases and syndromes; liver manifestations and hepatitis are examples of them. Parvovirus B19 hepatitis associated aplastic anemia and its coinfection with other hepatotropic viruses are relatively underrecognized, and there is sufficient evidence in the literature suggesting that B19 infections can cause a spectrum of liver diseases from elevation of transaminases to acute hepatitis to fulminant liver failure and even chronic hepatitis. It can also cause fatal macrophage activation syndrome and fibrosing cholestatic hepatitis. Parvovirus B19 is an erythrovirus that can only be replicate in pronormoblasts and hepatocytes, and other cells which have globosides and glycosphingolipids in their membrane can also be affected by direct virus injury due to nonstructural protein 1 persistence and indirectly by immune mediated injury. The virus infection is suspected in bone marrow aspiration in cases with sudden drop of hemoglobin and onset of transient aplastic anemia in immunosuppressed or immunocompetent patients and is confirmed either by IgM and IgG positive serology, PCR analysis, and in situ hybridization in biopsy specimens or by application of both. There is no specific treatment for parvovirus B19 related liver diseases, but triple therapy regimen may be effective consisting of immunoglobulin, dehydrohydrocortisone, and cyclosporine.

    Full Text Available A 21-year-old primigravida, at 32 weeks of gestation, presented with acute onset of respiratory failure and circulatory shock. Chest imaging showed findings suggestive of ruptured hydatid cyst, which was confirmed by histology post-thoracotomy. Tissue cultures from the removed cyst grew Mycobacterium tuberculosis also. She was successfully managed in the intensive care unit and was then discharged home on antituberculosis medications in addition to albendazole after prolonged hospitalization and a need for chest tube for bronchopleural fistula. Acute respiratory failure and anaphylactic shock secondary to ruptured pulmonary hydatid cyst and superimposed pulmonary tuberculosis in a pregnant lady should be considered in patients living in endemic areas.

    Coronary spasm is abnormal contraction of an epicardial coronary artery resulting in myocardial ischemia. Coronary spasm induces not only depressed myocardial contractility, but also incomplete myocardial relaxation, which leads to elevated ventricular filling pressure. We herein report the case of a 55-year-old woman who had repeated acute heart failure caused by coronary spasm. Acetylcholine provocation test with simultaneous right heart catheterization was useful for the diagnosis of elevated ventricular filling pressure as well as coronary artery spasm. We should add coronary spasm to a differential diagnosis for repeated acute heart failure.

    2014-01-01

    Full Text Available Glutaric Aciduria type I (GA-I is a rare organic acidemia, caused by mutations in the GCDH gene, and characterized by encephalopathic crises with neurological sequelae. We report herein a patient with GA-I who presented with severe acute renal failure requiring dialysis, following an acute diarrheal illness. Histopathological evaluation demonstrated acute tubular necrosis, and molecular diagnosis revealed the patient to be homozygous for a previously unreported mutation, p.E64D. As renal impairment is not part of the clinical spectrum typical to GA-I, possible associations of renal failure and the underlying inborn error of metabolism are discussed, including recent advancements made in the understanding of the renal transport of glutaric acid and its derivatives during metabolic disturbance in GA-I.

All ages and genders are concerned with a peak of incidence in girls in prepubertal age, even if the diseaseTINJAUAN PUSTAKA2has been diagnosed as early as 6 months. Autoimmune hepatitis may be classified in two major subgroups on a presence of a specific set of autoantibodies: smooth muscle antibody (SMA mostly with anti-actin specificity and/or by antinuclear antibody (ANA in type 1 and liver-kidney microsome antibody (LKM1 and/or the anti-liver cytosol in type 2. The histological hallmark is “interface hepatitis”, with a mononuclear cell infiltrate in the portal tracts, variable degrees of necrosis, and progressive fibrosis. The disease follows a chronic but fluctuating course usually progressing to cirrhosis and liver failure.The most frequent type onset is similar to that of an acute viral hepatitis with acute liver failure in some patients; about a third of patients have an insidious onset with progressive fatigue and jaundice while 10-15% are asymptomatic and are accidentally discovered by the finding of hepatomegaly and/or an increase of serum aminotransferase activity. There is a female predominance in both. LKM1-positive patients tend to present more acutely, at a younger age, and commonly have immunoglobulin A (IgA deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment and long-term prognosis are similar in both groups.Corticosteroids alone or in conjunction with azathioprine are the treatment of choice inducing remission in over 90% of patients. An alternative therapeutic strategy is cyclosporine. Withdrawal of immunosuppression is associated with high risk

    The Curcuma longa L. (CLL) rhizome has long been used to treat patients with hepatic dysfunction. CLL is a member of the ginger family of spices that are widely used in China, India, and Japan, and is a common spice, coloring, flavoring, and traditional medicine. This study was performed to evaluate the hepatoprotective activity of CLL extract and its active component curcumin in an acute carbon tetrachloride (CCl 4 )-induced liver stress model. Acute hepatic stress was induced by a single intraperitoneal injection of CCl 4 (0.1 ml/kg body weight) in rats. CLL extract was administered once a day for 3 days at three dose levels (100, 200, and 300 mg/kg/day) and curcumin was administered once a day at the 200 mg/kg/day. We performed alanine transaminase (ALT) and aspartate transaminase (AST). activity analysis and also measured total lipid, triglyceride, and cholesterol levels, and lipid peroxidation. At 100 g CLL, the curcuminoid components curcumin (901.63 ± 5.37 mg/100 g), bis-demethoxycurcumin (108.28 ± 2.89 mg/100 g), and demethoxycurcumin (234.85 ± 1.85 mg/100 g) were quantified through high liquid chromatography analysis. In CCl 4 -treated rats, serum AST and ALT levels increased 2.1- and 1.2-fold compared with the control. AST but not ALT elevation induced by CCl 4 was significantly alleviated in CLL- and curcumin-treated rats. Peroxidation of membrane lipids in the liver was significantly prevented by CLL (100, 200, and 300 mg/kg/day) on tissue lipid peroxidation assay and immunostaining with anti-4HNE antibody. We found that CLL extract and curcumin exhibited significant protection against liver injury by improving hepatic superoxide dismutase (p < 0.05) and glutathione peroxidase activity, and glutathione content in the CCl 4 -treated group (p < 0.05), leading to a reduced lipid peroxidase level. Our data suggested that CLL extract and curcumin protect the liver from acute CCl 4 -induced injury in a rodent model by suppressing

    The immunoregulatory molecules programmed death 1 (PD-1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) are associated with the dysfunction of antiviral effector T-cells, which leads to T-cell exhaustion and persistent viral infection in patients with chronic hepatitis C and chronic hepatitis B. Little is known about the role of PD-1 and CTLA-4 in patients with symptomatic acute hepatitis A (AHA). Peripheral blood mononuclear cells were isolated from seven patients with AHA and from six patients with nonviral acute toxic hepatitis (ATH) during the symptomatic and convalescent phases of the respective diseases; five healthy subjects acted as controls. The expression of PD-1 and CTLA-4 on T-cells was measured by flow cytometry. PD-1 and CTLA-4 expression during the symptomatic phase was significantly higher in the T-cells of AHA patients than in those of ATH patients or healthy controls (PD-1 18.3% vs 3.7% vs 1.6%, respectively, p<0.05; CTLA-4 23.5% vs 6.1% vs 5.9%, respectively, p<0.05). The levels of both molecules decreased dramatically during the convalescent phase of AHA, whereas a similar pattern was not seen in ATH. Our findings are consistent with a viral-protective effect of PD-1 and CTLA-4 as inhibitory molecules that suppress cytotoxic T-cells and thereby prevent the destruction of virus-infected hepatocytes in AHA.

    We have reported that tumor necrosis factor- (TNF-α) is critical for reduction of glomerular filtration rate (GFR) in rats with fulminant hepatic failure (FHF). The present study aims to evaluate the underlying mechanisms of decreased GFR during acute hepatic failure. Rats with FHF induced by D-galactosamine plus lipopolysaccharide (GalN/LPS) were injected intravenously with recombinant lentivirus harboring shRNA against the protein kinase C-α (PKC-α) gene (Lenti-shRNA-PKC-α). GFR, serum levels of aminotransferases, creatinine, urea nitrogen, potassium, sodium, chloride, TNF-α and endothelin-1 (ET-1), as well as type 1 inositol 1,4,5-trisphosphate receptor (IP3R1) expression in renal tissue were assessed. The effects of PKC-α silencing on TNF-α-induced IP3R1, specificity protein 1 (SP-1) and c-Jun N-terminal kinase (JNK) expression, as well as cytosolic calcium content were determined in glomerular mesangial cell (GMCs) with RNAi against PKC-α. Renal IP3R1 overexpression was abrogated by pre-treatment with Lenti-shRNA-PKC-α. The PKC- silence significantly improved the compromised GFR, reduced Cr levels, and reversed the decrease in glomerular inulin space and the increase in glomerular calcium content in GalN/LPS-exposed rats. TNF-α treatment increased expression of PKC-α, IP3R1, specificity protein 1 (SP-1), JNK and p-JNK in GMCs, and increased Ca2+ release and binding activity of SP-1 to the IP3R1 promoter. These effects were blocked by transfection of siRNA against the PKC-α gene, and the PKC-α gene silence also restored cytosolic [Ca2+]i. RNAi targeting PKC-α inhibited TNF-α-induced IP3R1 overexpression, and in turn improved compromised GFR in the development of acute kidney injury during FHF in rats.

    To investigate the expression of aquaporin-4 (AQP4) during brain edema in rats with thioacetamide-induced acute liver failure and encephalopathy. The rat model of acute hepatic failure and encephalopathy was induced by intraperitoneal injection of thioacetamide (TAA) at a 24-hour interval for 2 consecutive days. Thirty-two SD rats were randomly divided into the model group (n = 24) and the control group (normal saline, n = 8). And then the model group was further divided into 3 subgroups by the timepoint of decapitation: 24 h (n = 8), 48 h (n = 8) and 60 h (n = 8). Then we observed their clinical symptoms and stages of HE, indices of liver function and ammonia, liver histology and brain water content. The expression of AQP4 protein in brain tissues was measured with Western blot and the expression of AQP4mRNA with RT-PCR (reverse transcription-polymerase chain reaction). Typical clinical manifestations of hepatic encephalopathy occurred in all TAA-administrated rats. The model rats showed the higher indices of ALT (alanine aminotransferase), AST (aspartate aminotransferase), TBIL (total bilirubin) and ammonia than the control rats (P liver failure and encephalopathy plays a significant role during brain edema. AQP4 is one of the molecular mechanisms for the occurrence of brain edema in hepatic encephalopathy.

    The aim of this paper is to assess the clinical efficacy of non-invasive ventilation (NIV) in avoiding endotracheal intubation (ETI), to demonstrate clinical and gasometric improvement and to identify predictive risk factors associated with NIV failure. An observational prospective clinical study was carried out. Included Patients with acute respiratory disease (ARD) treated with NIV, from November 2006 to January 2010 in a Pediatric Intensive Care Unit (PICU). NIV was used in 151 patients with acute respiratory failure (ARF). Patients were divided in two groups: NIV success and NIV failure, if ETI was required. Mean age was 7.2±20.3 months (median: 1 min: 0,3 max.: 156). Main diagnoses were bronchiolitis in 102 (67.5%), and pneumonia in 44 (29%) patients. There was a significant improvement in respiratory rate (RR), heart rate (HR), pH, and pCO(2) at 2, 6, 12 and 24 hours after NIV onset (Papneia (P<0.001; odds ratio 15.8; 95% confidence interval: 3.42-71.4) and pneumonia (P<0.001, odds ratio 31.25; 95% confidence interval: 8.33-111.11). There were no major complications related with NIV. In conclusion this study demonstrates the efficacy of NIV as a form of respiratory support for children and infants with ARF, preventing clinical deterioration and avoiding ETI in most of the patients. Risk factors for failure were related with immaturity and severe infection.

    2017-01-01

    Full Text Available Acute renal failure can be caused by calcineurin inhibitors (CNIs, due to arteriolopathy and altered tubular function. Within this context, we present the case of a 14-month-old liver transplant recipient who suffered an acute polyuric renal failure during a short episode of hypercaloric feeding. In our case, CNI-induced distal RTA led to nephrocalcinosis and therefore to secondary nephrogenic diabetes insipidus. The diet with high renal solute load consequently resulted in an acute polyuric renal failure with severe hypernatremic dehydration. In conclusion, a hypercaloric diet in children with potentially impaired renal function due to therapy with CNIs requires precise calculation of the potential renal solute load and the associated fluid requirements.

    Full Text Available Organ failure is an important factor causing death in patients with severe acute pancreatitis (SAP. In recent years, thanks to the further study of pathophysiology of SAP and the continuous accumulation of experience and technology, substantial progress has been made in the diagnosis and treatment of SAP complicated by organ failure. The clinical features of SAP complicated by organ failure and the measures to be strengthened in the treatment of SAP are summarized. Currently, it is thought that organ failure tends to appear once SAP occurs, so timely, standardized treatment can shorten the course of disease and significantly reduce mortality.

    In heart failure patients, exhaled acetone concentration, a noninvasive biomarker, is increased according to heart failure severity. Moreover, exhaled acetone concentration is also known to be affected by diabetes mellitus. However, there have been no reports on exhaled acetone concentration in heart failure patients with diabetes mellitus. A 77-year old man was admitted to our hospital with acute decompensated heart failure and atrioventricular block. He had controlled diabetes mellitus under insulin treatment with hemoglobin A1c of 6.5%. He underwent treatment of diuretics and permanent pacemaker implantation. His condition improved and he was discharged at Day 12. Due to the heart failure improvement, his levels of exhaled acetone concentration decreased from 1.623 ppm at admission to 0.664 ppm at discharge. This is the first report to reveal a change of exhaled acetone concentration in a diabetic patient with acute decompensated heart failure.

    Full Text Available Introduction: Reasons for acute renal failure in hospitalized infants were sepsis, hypovolemia, asphyxia, respiratory distress syndrome, surgical interventions and congenital heart defects. The aim of this study was to determine the frequency and and main etiologies, and early outcome of neonatal acute renal failure. Materials and Methods: At Intensive Care Unit, Clinical Center Tuzla, from 15. 01. 2013 to 15. 01. 2015 in 21 newborn was diagnosed renal failure, based on the amount of excreted urine and serum creatinine. Results: The prevalence of renal failure was 6.84%, with a higher incidence of female. 33.3% of infants were term neonates. Oliguria was diagnosed in 71.4% of newborns. Sepsis was the most common predisposing factor for the development of renal failure, associated with high mortality. Other causes of renal failure were perinatal hypoxia, RDS, surgical interventions and congenital heart defects. There was a positive correlation between the gestational age of the newborn and serum creatinine. Discussion: Early prevention of risk factors with rapid diagnosis and effective treatment, can affect further outcome of acute renal failure in infants.

  7. 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.

    Purpose: Although hepatic perfusion abnormalities have been reported in patients with acute pancreatitis, hepatic perfusion with severe acute pancreatitis (SAP) has not been quantitatively evaluated in humans. Therefore, we investigated hepatic perfusion in patients with SAP using perfusion CT. Materials and methods: Hepatic perfusion CT was performed in 67 patients with SAP within 3 days after symptom onset. The patients were diagnosed as having SAP according to the Atlanta criteria. Fifteen cases were established as a control group. Perfusion CT was obtained for 54 s beginning with a bolus injection of 40 ml of contrast agent (600–630 mgI/kg) at a flow rate of 4 ml/s. Perfusion data were analyzed by the dual-input maximum slope method to obtain hepatic arterial perfusion (HAP) and hepatic portal perfusion (HPP). Finally, we compared HAP and HPP in SAP patients with those in the control group, respectively. Results: Average HAP was significantly higher in SAP patients than in the control group (75.1 ± 38.0 vs. 38.2 ± 9.0 ml/min/100 ml; p < 0.001). There was no significant difference in average HPP between SAP patients and the control group (206.7 ± 54.9 vs. 204.4 ± 38.5 ml/min/100 ml; p = 0.92). Conclusion: Using quantitative analysis on perfusion CT, we first demonstrated an increase of HAP in the right hepatic lobe in SAP patients.

    Full Text Available Visuo-spatial neglect and vestibular disorders have common clinical findings and involve the same cortical areas. We questioned (1 whether visuo-spatial hemineglect is not only a disorder of spatial attention but may also reflect a disorder of higher cortical vestibular function and (2 whether a vestibular tone imbalance due to an acute peripheral dysfunction can also cause symptoms of neglect or extinction. Therefore, patients with an acute unilateral peripheral vestibular failure (VF were tested for symptoms of hemineglect.Twenty-eight patients with acute VF were assessed for signs of vestibular deficits and spatial neglect using clinical measures and various common standardized paper-pencil tests. Neglect severity was evaluated further with the Center of Cancellation method. Pathological neglect test scores were correlated with the degree of vestibular dysfunction determined by the subjective visual vertical and caloric testing.Three patients showed isolated pathological scores in one or the other neglect test, either ipsilesionally or contralesionally to the VF. None of the patients fulfilled the diagnostic criteria of spatial hemineglect or extinction.A vestibular tone imbalance due to unilateral failure of the vestibular endorgan does not cause spatial hemineglect, but evidence indicates it causes mild attentional deficits in both visual hemifields.

    Acute heart failure and/or cardiogenic shock are frequently triggered by ischemic coronary events. 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. The inodilator levosimendan offers potential benefits due to a range of distinct effects including positive inotropy, restoration of ventriculo-arterial coupling, increases in tissue perfusion, and anti-stunning and anti-inflammatory effects. In clinical trials levosimendan improves symptoms, cardiac function, hemodynamics, and end-organ function. Adverse effects are generally less common than with other inotropic and vasoactive therapies, with the notable exception of hypotension. The decision to use levosimendan, in terms of timing and dosing, is influenced by the presence of pulmonary congestion, and blood pressure measurements. Levosimendan should be preferred over adrenergic inotropes as a first line therapy for all ACS-AHF patients who are under beta-blockade and/or when urinary output is insufficient after diuretics. Levosimendan can be used alone or in combination with other inotropic or vasopressor agents, but requires monitoring due to the risk of hypotension. Copyright © 2016 The Authors.

    2011-09-01

    Full Text Available This study aimed to determine if there are differences in inflammatory markers in the acute phase between systolic heart failure and heart failure with preserved systolic function. One hundred and thirty-one patients with acute heart failure were recruited consecutively. At admission, plasma fibrinogen, Creactive protein, sialic acid, von Willebrand factor, vascular endothelial growth factor, interleukin-6 and NTproBNP were all evaluated. If the ejection fraction was 45% or over patients were included in the HF-PSF group; the remaining patients were included in the SHF group. The HF-PSF patients were older (72±10 vs 63±12 years, P<0.001, presented a higher rate of atrial fibrillation (56.1 vs 21.3%, P<0.001, and had a lower rate of hemoglobin (12.2±2 vs 13.3±2.1 g/dL, P<0.01. No significant differences were observed in the inflammation markers analyzed among SHF and HFPSF groups. In the acute phase of heart failure there is a marked elevation of inflammatory markers but there are no differences in the inflammatory markers analyzed between the two different types of heart failure

  12. Rhabdomyolysis and Acute Renal Failure after Gardening

    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.

    To assess retrospectively the cause of hepatic failure related to hepatic arterial embolization (HAE) for hemostasis after pancreaticoduodenectomy or hepatic lobectomy. Between June 1993 and March 2006, Twenty HAEs in 17 patients (15 men, two women; mean age, 64 years) were performed. Angiographic findings, including portal vein stenosis, collateral arterial pathways after HAE, and the difference of embolic materials, were recorded. The morbidity (hepatic failure and abscess) and mortality were detailed according to collateral arterial pathways, portal vein stenosis, and embolic material used. Bleeding was controlled in all patients, although two patients required repeat embolization. Hepatic failure (n = 8) and abscess (n = 2) arose in nine of 20 HAEs. Death occurred after six of eight HAEs complicated by hepatic failure. The morbidity and mortality rates of HAE were 45% and 30%, respectively. Hepatic complication was eight times more likely to occur (P = .005) in cases with no hepatic collaterals involving hepatic, replaced, or accessory hepatic arteries. Death was observed only in the cases without hepatic collaterals (P = .011). The correlation between the embolization outcome and the presence of portal vein stenosis or the difference of embolic materials was not significant (P > .61). HAE can be used to successfully control bleeding secondary to hepatic arterial rupture. In the absence of hepatic collaterals, collateral circulation distal to the occlusion from nonhepatic sources may be inadequate and lead to hepatic failure after HAE. Copyright © 2011 SIR.

    2015-01-01

    Full Text Available Complement-mediated hemolytic uremic syndrome (otherwise known as atypical HUS is a rare disorder of uncontrolled complement activation that may be associated with heart failure. We report the case of a 49-year-old female with no history of heart disease who presented with microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. Given her normal ADAMSTS13 activity, evidence of increased complement activation, and renal biopsy showing evidence of thrombotic microangiopathy, she was diagnosed with complement-mediated HUS. She subsequently developed acute hypoxemic respiratory failure secondary to pulmonary edema requiring intubation and mechanical ventilation. A transthoracic echocardiogram showed evidence of a Takotsubo cardiomyopathy with an estimated left ventricular ejection fraction of 20%, though ischemic cardiomyopathy could not be ruled out. Treatment was initiated with eculizumab. After several failed attempts at extubation, she eventually underwent tracheotomy. She also required hemodialysis to improve her uremia and hypervolemia. After seven weeks of hospitalization and five doses of eculizumab, her renal function and respiratory status improved, and she was discharged in stable condition on room air and independent of hemodialysis. Our case illustrates a rare association between acute systolic heart failure and complement-mediated HUS and highlights the potential of eculizumab in stabilizing even the most critically-ill patients with complement-mediated disease.

    The radioimmunoassay (RIA) and counterimmunoelectrophoretic (CIE) methods were compared in detecting hepatitis B antigen (HB/sub s/Ag) in 407 acute and 336 convalescent sera of adults with viral hepatitis. The CIE method demonstrated that 41 percent of acute and 28 percent of 14- to 17-day serum specimens were HB/sub s/Ag-positive. The RIA method demonstrated seropositivity in 60 percent of acute and 56 percent of convalescent specimens (P less than .001). Eighty-four percent of coded specimens initially positive for HB/sub s/Ag by RIA were found to have subtype antigenic determinants d or y; 92 percent of the HB/sub s/Ag-negative controls were negative for subtype antigens, confirming the specificity of the RIA test. RIA subtyping data corroborated earlier work with immunodiffusion techniques. (U.S.)

    The purpose of the study was to compare the EASI system with the standard 12-lead surface electrocardiogram (ECG) for the accuracy in detecting the main electrocardiographic parameters (J point, PR, QT, and QRS) commonly monitored in patients with acute coronary syndromes or heart failure. In this observational comparative study, 253 patients who were consecutively admitted to the coronary care unit with acute coronary syndrome or heart failure were evaluated. In all patients, two complete 12-lead ECGs were acquired simultaneously. A total of 6,072 electrocardiographic leads were compared (3,036 standard and 3,036 EASI). No significant differences were found between the investigate parameters of the two measurement methods, either in patients with acute coronary syndrome or in those with heart failure. This study confirmed the accuracy of the EASI system in monitoring the main ECG parameters in patients admitted to the coronary care unit with acute coronary syndrome or heart failure.

    Hepatitis E virus (HEV) is an emerging infectious agent in developed countries. HEV genotypes 1 (G1) and 3 (G3) have been identified in environmental and clinical samples in Europe. In Israel, the overall prevalence of anti-HEV IgG antibodies was found to be 10.6%; however, reports of HEV infection are scarce. In this study, the presence of HEV in Israel was investigated using 169 sewage samples from 32 treatment facilities and 49 samples from acute hepatitis patients, all collected between 2013 and 2015. Fourteen sewage samples, from Haifa (11/18 samples), Tel Aviv (2/29 samples), and Beer Sheva (1/17 samples), regions with good sanitary conditions and middle-high socioeconomic populations, were HEV positive. Among the patient samples, 6.1% (3/49) were HEV positive, all returning travelers from India. Genotype analysis revealed G1 HEV in patients and G3 HEV sequences in sewage. Evidence that HEV could be establishing itself in our region may justify more active surveillance to monitor its spread. PMID:27246446

    Viral hepatitis is a liver infection caused by one of the six hepatitis viruses: hepatitis A, B, C, D, E, and G virus (HAV to HEV and HGV). These agents differ in their biological, immunological, pathological and epidemiological characteristics. They cause infections that, when symptomatic, lead to clinical manifestations and laboratory findings that are not specific to a particular virus, often making differential diagnosis difficult, especially when no knowledge is available regarding the patient's medical history or the epidemiological background. A number of acute-phase serological markers, such as anti-HAV, anti-HBc, anti-HDV and anti-HEV IgM antibodies, are able to provide a clear indication of an infection caused by HAV, HBV, HDV or HEV. Anti-HCV antibodies and HGV/RNA are used for the diagnosis of HCV and HGV infections. The importance of each of these markers will be reviewed, and different factors that can interfere with the diagnosis of acute infections caused by these viruses will be described.

    Liver transplantation has been remarkably effective in the treatment in patients with end-stage liver disease. However, disparity between solid-organ supply and increased demand is the greatest limitation, resulting in longer waiting times and increase in mortality of transplant recipients. This situation creates the need to seek alternatives to orthotopic liver transplantation.Hepatocyte transplantation or liver cell transplantation has been proposed as the best method to support patients. The procedure consists of transplanting individual cells to a recipient organ in sufficient quantity to survive and restore the function. The capacity of hepatic regeneration is the biological basis of hepatocyte transplantation. This therapeutic option is an experimental procedure in some patients with inborn errors of metabolism, fulminant hepatic failure and acute and chronic liver failure, as a bridge to orthotopic liver transplantation. In the Hospital La Fe of Valencia, we performed the first hepatocyte transplantation in Spain creating a new research work on transplant program. Copyright 2009 AEC. Published by Elsevier Espana.

    Acute renal failure is common in the neonatal intensive care unit but is often not recognized in its early phases, when it is potentially reversible. The typical patient with acute renal failure is premature, but many term infants are also at risk. One such group is those with severe bleeding, such as a subgaleal hemorrhage. In these cases, hypovolemia can quickly progress to ischemia, which affects many organs but has profound effects on the kidney. In term infants, acute renal failure is most commonly diagnosed in those with perinatal depression. This article presents a unique case of an infant with subgaleal and intracranial bleeding that resulted in acute renal failure requiring peritoneal dialysis in the hopes of the eventual restoration of kidney function.

    Alpha-fetoprotein is produced by a variety of tumors such as hepatocellular carcinoma, hepatoblastoma, and germ cell tumors of the ovary and testes. However, we present a case of significantly elevated serum alpha-fetoprotein without evidence of malignant disease in a patient who is a carrier of chronic hepatitis B. A 60-year-old Korean man presented with markedly increased alpha-fetoprotein (2350 ng/mL; normal 7 × 105 IU/mL). Our patient was diagnosed with acute exacerbation of chronic hepatitis B, and we presumed that this condition might be related to extremely elevated alpha-fetoprotein. When our patient was treated with entecavir, the serum alpha-fetoprotein level immediately decreased, in parallel with the hepatitis B virus deoxyribonucleic acid copy number. We report a rare case of extremely elevated alpha-fetoprotein due to acute exacerbation of chronic hepatitis B without any malignancy, and a decrease in this tumor marker simultaneous with a decrease in hepatitis B virus deoxyribonucleic acid copy number on entecavir treatment. This case report is important due to the rarity of the case; furthermore, it provides details of a diagnostic process for a variety of benign diseases and malignant tumors that should be considered in patients with elevated alpha-fetoprotein. Thus, we present a case report, along with a review, that will be helpful for diagnosis and treatment of patients with elevated alpha-fetoprotein.

    2007-04-01

    Full Text Available SUMMARY: Acute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one. In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels.RESUMEN: La insuficiencia renal aguda es un sindrome que característicamente cursa con niveles plasmáticos elevados de urea y creatinina. Sin embargo, hay situaciones clínicas en las cuales este sindrome puede cursar con un incremento de la creatininemia sin presentar elevación de la uremia. En este reporte presentamos un caso clínico de una insuficiencia renal aguda con uremia normal secundaria a una pielonefritis aguda en un paciente con riñón único. El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal.

    Organ failure is a major determinant of mortality in patients with acute pancreatitis. These patients usually require admission to high dependency or intensive care units and consume considerable health care resources. Given a low incidence rate of organ failure and a lack of large non-interventional studies in the field of acute pancreatitis, the characteristics of organ failure that influence outcomes of patients with acute pancreatitis remain largely unknown. Therefore, the Pancreatitis Across Nations Clinical Research and Education Alliance (PANCREA) aims to conduct a meta-analysis of individual patient data from prospective non-interventional studies to determine the influence of timing, duration, sequence, and combination of different organ failures on mortality in patients with acute pancreatitis. Pancreatologists currently active with acute pancreatitis clinical research will be invited to contribute. To be eligible for inclusion patients will have to meet the criteria of acute pancreatitis, develop at least one organ failure during the first week of hospitalization, and not be enrolled into an intervention study. Raw data will then be collated and checked. Individual patient data analysis based on a logistic regression model with adjustment for confounding variables will be done. For all analyses, corresponding 95% confidence intervals and P values will be reported. This collaborative individual patient data meta-analysis will answer important clinical questions regarding patients with acute pancreatitis that develop organ failure. Information derived from this study will be used to optimize routine clinical management and improve care strategies. It can also help validate outcome definitions, allow comparability of results and form a more accurate basis for patient allocation in further clinical studies.

    Objective: This study was done to evaluate frequency of acute renal failure ( ARF ), its causes and out come of the patients. Study Design: Descriptive analytic study Place and Duration of Study: March to Dec 2007 at Combined Military Hospital Lahore. Patients and Methods: All patients, admitted in different wards of the hospital, who developed acute renal failure (doubling of serum creatinine measured on two occasions 12 hours apart), were included in this study. Results: A total of 39 patients were included in the study. Males were 19 (48.71%) and 20 (51.28%) were female. Mean age of patients was 40.2 years (SD=18.0). The major cause was acute Gastroenteritis seen in 23 (58.97%) cases. Others developed ARF due to, Abruptio Placentae 5 (12.82%), Postoperative 5 (12.82%), Eclampsia 3 (7.69%) and Drug induced 3 (7.69%) . Oliguric phase developed in 28 (71.79%) patients and lasted for 8.45 +- 4.16 days. Of these 17 (60.71%) patients had acute gastroenteritis. Conclusion: Gastroenteritis is the most common and important cause of ARF though gynaecological and surgical etiologies must be kept in mind. It is evident that the gynaecological and surgical patients need critical peri-partum and peri-operative monitoring to prevent development of ARF. Early institution of therapy will prevent subsequent morbidity associated with this disease. (author)

  7. Combined adenovirus-mediated artificial microRNAs targeting mfgl2, mFas, and mTNFR1 protect against fulminant hepatic failure in mice.

    Full Text Available Hepatitis B virus (HBV-related acute-on-chronic liver failure (ACLF has a poor prognosis with high in-hospital mortality. Hepatic and circulating inflammatory cytokines, such as fibrinogen like protein 2 (fgl2, FasL/Fas, and TNFα/TNFR1, play a significant role in the pathophysiology of ACLF. This study aimed to investigate the therapeutic effect of recombinant adenoviral vectors carrying constructed DNA code for non-native microRNA (miRNA targeting mouse fgl2 (mfgl2 or both mFas and mTNFR1 on murine hepatitis virus (MHV-3-induced fulminant hepatitis in BALB/cJ mice. Artificial miRNA eukaryotic expression plasmids against mfgl2, mFas, and mTNFR1 were constructed, and their inhibitory effects on the target genes were confirmed in vitro. pcDNA6.2-mFas-mTNFR1- miRNA,which expresses miRNA against both mFas and mTNFR1 simultaneously,was constructed. To construct a miRNA adenovirus expression vector against mfgl2, pcDNA6.2-mfgl2-miRNA was cloned using Gateway technology. Ad-mFas-mTNFR1- miRNA was also constructed by the same procedure. Adenovirus vectors were delivered by tail-vein injection into MHV-3-infected BALB/cJ mice to evaluate the therapeutic effect. 8 of 18 (44.4% mice recovered from fulminant viral hepatitis in the combined interference group treated with Ad-mfgl2-miRNA and Ad-mFas-mTNFR1-miRNA. But only 4 of 18 (22.2% mice receiving Ad-mfgl2-miRNA and 3 of 18 (16.7% mice receiving Ad-mFas-mTNFR1- miRNA survived. These adenovirus vectors significantly ameliorated inflammatory infiltration, fibrin deposition, hepatocyte necrosis and apoptosis, and prolonged survival time. Our data illustrated that combined interference using adenovirus-mediated artificial miRNAs targeting mfgl2, mFas, and mTNFR1 might have significant therapeutic potential for the treatment of fulminant hepatitis.

    Full Text Available Mycoplasma pneumonia is a major cause of respiratory infections in school-aged children. Most M. pneumonia infections in adults involve the respiratory tract. Extrapulmonary manifestations of M. pneumonia infection may be found in the skin, cardiovascular, neurologic and hematologic systems. Concomitant liver disease is rare in adults. Here, we report an unusual case of a patient who presented with fever and abdominal pain, but without pulmonary manifestations. The laboratory work-up demonstrated a hepatocellular pattern of acute hepatitis caused by M. pneumonia infection. Symptoms subsided and laboratory parameters improved with antibiotics treatment. Thus, this case can help raise clinicians' awareness of the possibility of M. pneumonia infection, with or without lung involvement, as a part of the evaluation of undetermined hepatitis.

    A young female with sickle cell disease was treated for biopsy-proven IgA nephropathy. Serum creatinine levels resolved to normal range, but a year later, she presented with oedema, hypertension and acute renal failure. A repeat renal biopsy showed acute-on-chronic thrombotic microangiopathy (TMA). We suggest that circulating microparticles could be a pathophysiological link between sickle cell disease and the development of renal TMA. This case emphasizes the importance of a further biopsy for acutely declining renal function, even when a definite diagnosis has been made from a previous biopsy. PMID:25949348

    Diaphragm atrophy is associated with delayed weaning from mechanical ventilation and increased mortality in critically ill adults. We sought to test for the presence of diaphragm atrophy in children with acute respiratory failure. Prospective, observational study. Single-center tertiary noncardiac PICU in a children's hospital. Invasively ventilated children with acute respiratory failure. Diaphragm thickness at end-expiration and end-inspiration were serially measured by ultrasound in 56 patients (median age, 17 mo; interquartile range, 5.5-52), first within 36 hours of intubation and last preceding extubation. The median duration of mechanical ventilation was 140 hours (interquartile range, 83-201). At initial measurement, thickness at end-expiration was 2.0 mm (interquartile range, 1.8-2.5) and thickness at end-inspiration was 2.5 mm (interquartile range, 2-2.8). The change in thickness at end-expiration during mechanical ventilation between first and last measurement was -13.8% (interquartile range, -27.4% to 0%), with a -3.4% daily atrophy rate (interquartile range, -5.6 to 0%). Thickening fraction = ([thickness at end-inspiration - thickness at end-expiration]/thickness at end-inspiration) throughout the course of mechanical ventilation was linearly correlated with spontaneous breathing fraction (beta coefficient, 9.4; 95% CI, 4.2-14.7; p = 0.001). For children with a period of spontaneous breathing fraction less than 0.5 during mechanical ventilation, those with exposure to a continuous neuromuscular blockade infusion (n = 15) had a significantly larger decrease in thickness at end-expiration compared with children with low spontaneous breathing fraction who were not exposed to a neuromuscular blockade infusion (n = 18) (-16.4%, [interquartile range, -28.4% to -7.0%] vs -7.3%; [interquartile range, -10.9% to -0%]; p = 0.036). Diaphragm atrophy is present in children on mechanical ventilation for acute respiratory failure. Diaphragm contractility, measured as

    Full Text Available Abstract Background Identification of risk factors of acute hepatitis C virus (HCV infection in Egypt is crucial to develop appropriate prevention strategies. Methods We conducted a case–control study, June 2007-September 2008, to investigate risk factors for acute HCV infection in Egypt among 86 patients and 287 age and gender matched controls identified in two infectious disease hospitals in Cairo and Alexandria. Case-patients were defined as: any patient with symptoms of acute hepatitis; lab tested positive for HCV antibodies and negative for HBsAg, HBc IgM, HAV IgM; and 7-fold increase in the upper limit of transaminase levels. Controls were selected from patients’ visitors with negative viral hepatitis markers. Subjects were interviewed about previous exposures within six months, including community-acquired and health-care associated practices. Results Case-patients were more likely than controls to have received injection with a reused syringe (OR=23.1, CI 4.7-153, to have been in prison (OR=21.5, CI 2.5-479.6, to have received IV fluids in a hospital (OR=13.8, CI 5.3-37.2, to have been an IV drug user (OR=12.1, CI 4.6-33.1, to have had minimal surgical procedures (OR=9.7, CI 4.2-22.4, to have received IV fluid as an outpatient (OR=8, CI 4–16.2, or to have been admitted to hospital (OR=7.9, CI 4.2-15 within the last 6 months. Multivariate analysis indicated that unsafe health facility practices are the main risk factors associated with transmission of HCV infection in Egypt. Conclusion In Egypt, focusing acute HCV prevention measures on health-care settings would have a beneficial impact.

    Full Text Available Hepatitis associated aplastic anemia (HAAA is a rare syndrome in which severe aplastic anemia (SAA complicates the recovery of acute hepatitis (AH. HAAA is described to occur with AH caused by viral infections and also with idiopathic cases of AH and no clear etiology of liver injury. Clinically, AH can be mild to fulminant and transient to persistent and precedes the onset SAA. It is assumed that immunologic dysregulation following AH leads to the development of SAA. Several observations have been made to elucidate the immune mediated injury mechanisms, ensuing from liver injury and progressing to trigger bone marrow failure with the involvement of activated lymphocytes and severe T-cell imbalance. HAAA has a very poor outcome and often requires bone marrow transplant (BMT. The findings of immune related myeloid injury implied the use of immunosuppressive therapy (IST and led to improved survival from HAAA. We report a case of young male who presented with AH resulting from the intake of muscle building protein supplements and anabolic steroids. The liver injury slowly resolved with supportive care and after 4 months of attack of AH, he developed SAA. He was treated with IST with successful outcome without the need for a BMT.

    Full Text Available Abstract Background Colchicine is used in the treatment and prophylaxis of gout. It possesses a narrow therapeutic window, frequently resulting in dose-limiting gastrointestinal side-effects such as diarrhoea and emesis. As colchicine is a cellular anti-mitotic agent, the most serious effects include myelosuppression, myoneuropathy and multiple organ failure. This occurs with intentional overdose or with therapeutic dosing in patients with reduced clearance of colchicine due to pre-existing renal or hepatic impairment. Acute pancreatitis has rarely been reported, and only in association with severe colchicine overdose accompanied by multi-organ failure. Case presentation We report a case of acute pancreatitis without other organ toxicity related to recent commencement of colchicine for acute gout, occurring in an elderly male with pre-existing renal impairment. Conclusion 1 Colchicine should be used with care in elderly patients or patients with impaired renal function. 2 Aside from myelosuppression, myoneuropathy and multiple organ failure, colchicine may now be associated with acute pancreatitis even with therapeutic dosing; this has not previously being reported.

    Full Text Available ObjectiveTo construct a hybrid bioartificial liver support system and to investigate its safety and efficacy in patients with hepatitis B virus (HBV-related acute-on-chronic liver failure (ACLF. MethodsA hollow fiber bioreactor was constructed using cultured HepG2 cells transfected with human augmenter of liver regeneration gene. Patients with HBV-related ACLF who were hospitalized in our hospital from May 2009 to August 2011 were randomly divided into treatment group (n=10 and control group (n=10. The treatment group was treated using the hybrid bioartificial liver support system, while the control group was treated with conventional plasma exchange. Comparison of means between the two groups was made by independent-samples t test, and comparison of variables before and after treatment was made by paired t test. ResultsOf the 10 patients in treatment group, 7 had improvement in clinical symptoms and were discharged, 1 died of hepatic encephalopathy, 1 died of hepatorenal syndrome, and 1 died of liver failure after discharge. Of the 10 patients in control group, 5 survived, 1 underwent liver transplantation, and 4 died of liver failure. Before treatment, the treatment group and control group had model for end-stage liver disease (MELD scores of 24.26±2.54 and 24.71±2.79, respectively, without significant difference between the two groups (t=1.971, P=0.064. The treatment group had MELD scores of 21.71±2.92, 22.10±4.46, and 19.90±5.43 after 3 days, 1 week, and 4 weeks, respectively, of treatment. At the end of one-year follow-up, the mean serum alpha-fetoprotein levels were 14.24 ng/ml in treatment group and 11.32 ng/ml in control group, and no space-occupying lesions in the liver were found through abdominal ultrasound. ConclusionThe constructed hybrid bioartificial liver support system is effective and safe in the treatment of HBV-related ACLF.

    Full Text Available ObjectiveTo perform a retrospective analysis of patients with liver failure to investigate the causative factors and related risk factors that may affect patient prognosis. MethodsThe clinical, demographic, and laboratory data of 79 consecutive patients diagnosed with liver failure and treated at our hospital between January 2010 and January 2012 (58 males and 21 females; age range: 16-74 years old were collected from the medical records. To identify risk factors of liver failure, the patient variables were assessed by Student’s t-test (continuous variables or Chi-squared test (categorical variables. Multivariate logistic regression analysis was used to investigate the relation between patient outcome and independent risk factors. ResultsThe 79 cases of liver failure were grouped according to disease severity: acute liver failure (n=6; 5 died, subacute liver failure (n=35; 19 died, and chronic liver failure (n=38; 28 died. The overall rate of death was 66%. The majority of cases (81% were related to hepatitis B virus infection. While the three groups of liver failure severity did not show significant differences in sex, mean age, occupation, presence of potassium disorder, total bilirubin (TBil or total cholesterol (CHO at admission, or lowest recorded level of CHO during hospitalization, there were significant intergroup differences in highest recorded TBil level, prothrombin activity (PTA at admission, and highest and lowest recorded PTA, and highest recorded level of CHO. Five independent risk factors were identified: the highest recorded TBil level during hospitalization, presence of infection, hepatorenal syndrome, gastrointestinal bleeding, and hepatic encephalopathy. ConclusionThe major cause of liver failure in this cohort of patients was hepatitis infection, and common biomarkers of liver function, such as TBil, CHO and PTA, may indicate patients with poor prognosis despite clinical intervention. Complications should be addressed as

    Full Text Available OBJECTIVE: To evaluate viral vaccine antibody levels in children with acute lymphoblastic leukemia after chemotherapy and after vaccine booster doses. METHODS: Antibody levels against hepatitis B, rubella, measles and mumps vaccine antigens were evaluated in 33 children after completing chemotherapy (before and after vaccine booster doses and the results were compared to the data of 33 healthy children matched for gender, age and social class. RESULTS: After chemotherapy, 75.9%, 67.9%, 59.3% and 51.7% of the patients showed low antibody titers that would be unlikely to protect against exposure to measles, rubella, hepatitis B and mumps, respectively. After receiving a vaccine booster dose for these antigens the patients had high antibody levels consistent with potential protection against measles, mumps and hepatitis B, but not against rubella. CONCLUSION: Extra doses of measles-mumps-rubella plus hepatitis B vaccines are recommended in acute lymphoblastic leukemia patients submitted to treatment after hematologic recovery. After this, viral vaccine antibody levels should be verified to define the individual's protective status.

    Mysterious deaths of archeologists after opening Egyptian tombs have been suspected, but never proved, to be secondary to inhalation of mycotoxin. We observed a case of acute renal failure (ARF) due to inhalation of ochratoxin A produced by a mould of the species Aspergillus ochraceus. After working 8 h in a granary closed for several months, a farmer and his wife suffered respiratory distress; the woman developed non-oliguric ARF and biopsy revealed tubulonecrosis. A strain of Aspergillus ochraceus producing ochratoxin was isolated from the wheat.

    Hyperventilation is frequently used to prevent or postpone the development of cerebral edema and intracranial hypertension in patients with fulminant hepatic failure (FHF). The influence of such therapy on regional cerebral blood flow (rCBF) remains, however, unknown. In this study the CBF......-distribution pattern was determined within the first 12 hours after development of hepatic encephalopathy (HE) stage 4 before and during hyperventilation. Ten consecutive patients (median age 48 [range 33-57] years) with FHF and 9 healthy controls (median age 54 [24-58] years) had rCBF determined by single photon...... emission computed tomography (SPECT) using intravenous injection of 133Xenon. For determination of high resolution CBF pattern, the patients were also studied with 99mTc-hexa-methylpropyleneamine oxime (HMPAO) in the hyperventilation condition. There was no significant difference in the rCBF distribution...

    Full Text Available Pediatric acute liver failure (PALF is a complex syndrome with rapid progression, and the cause of PALF is age-dependent. This article analyzes the common causes of PALF in clinical practice, including infection factors, inherited metabolic factors, poisoning and drugs, abnormal perfusion, and autoimmune diseases, among which infection factors are the most common cause. With the improvement in diagnosis and treatment techniques, the diagnostic rate of PALF caused by inherited metabolic diseases and autoimmune diseases keeps increasing. Due to the small number of PALF patients, there lacks experience in etiological diagnosis. This article summarizes related reports, in order to provide a reference for screening the causes of PALF.

    To assess results with NIV in acute hypercapneic respiratory failure and to identify outcome predictors. This was a retrospective observational study on consecutive patients presenting with acute type II respiratory failure and meeting criteria for NIV use over a 5 year period. Patients presenting with haemodynamic instability, inability to protect their airway, malignant arrhythmias and recent oesophageal surgery were excluded. Univariate and Multivariate regression analysis was used to determine the impact on survival. A p value of 35 Meq/L (adjusted Odds ratio 0.9; 95% CI 0.83, 0.98, p < 0.015) identified those less at risk for intubation. NIV was found to be both safe and effective in the management of acute hypercapneic respiratory failure. Sepsis and serum HCO/sub 3/ at admission identified patients having poor outcomes (JPMA 60:13; 2010). (author)

    We evaluated the clinical and virological characteristics of hepatitis A virus infection in persons concomitantly infected with hepatitis B virus (HBV) or hepatitis C virus (HCV). We enrolled 21 patients with acute hepatitis A and chronic hepatitis with no sign of liver cirrhosis, 13 patients who were positive for hepatitis B surface antigen (case B group), 8 patients who were anti-HCV positive (case C group), and 21 patients with acute hepatitis A without a preexisting liver disease (control A group). Two control groups of patients with chronic hepatitis B (control B group) or C (control C group) were also chosen. All control groups were pair-matched by age and sex with the corresponding case group. Fulminant hepatitis A was never observed, and hepatitis A had a severe course in 1 patient in the case B group and in 1 patient in the control A group. Both patients recovered. On admission, HBV DNA was detected in 1 patient in the case B group (7.7%) and in 13 patients (50%) in the control B group; HCV RNA was found in no patient in the case C group and in 16 patients (81.2%) in the control C group. Of 9 patients in the case B group who were followed up for 6 months, 3 became negative for hepatitis B surface antigen and positive for hepatitis B surface antibody, 2 remained positive for hepatitis B surface antigen and negative for HBV DNA, and 4 became positive for HBV DNA with a low viral load [corrected] Of 6 patients in the case C group who were followed up for 6 months, 3 remained negative for HCV RNA, and 3 had persistently low viral loads. Concomitant hepatitis A was always self-limited, associated with a marked inhibition of HBV and HCV genomes, and possibly had a good prognosis for the underlying chronic hepatitis.

    The purpose of this study was to evaluate the clinical features and the characteristics of MR images of patients with end-stage hepatic failure. We reviewed the MR findings and clinical features of 31 consecutive patients (20 men, 11 women=31, mean age 58.7 years) who had been diagnosed with clinical hepatic encephalopathy. Associations between the lesion locations on each MR sequence were analyzed using a binominal test. The clinical and MR findings were compared in relation to the etiology and clinical status. The most frequently involved site, seen as high signal intensity on T2-W images, was the corpus callosum (20 patients), followed by the dentate nucleus (16 patients) and the globus pallidus (13 patients). Significant associations were seen between the pallidus and the crus cerebri, between the crus cerebri and the red nucleus, between the crus cerebri and the dentate nucleus, and between the red nucleus and the dentate nucleus on the T2-W and DW images (P<0.004). The crus cerebri, red nucleus, and dentate nucleus were involved concurrently with the corpus callosum more frequently in hepatic encephalopathy grades 3 and 4. Concurrent involvement of the globus pallidus-crus cerebri-red nucleus-dentate nucleus axis was the main MR pattern in end-stage hepatic encephalopathy, which connected with various areas of the brain. We hypothesize that these overlapping MR features could be regarded as an entity denoted as the ''hepatic encephalopathy continuum''. (orig.)
