Abstract
Acute liver failure is a rare condition involving the rapid development, progression, and worsening of liver dysfunction, characterised by coagulopathy and encephalopathy, and has a high mortality unless liver transplantation is performed. Population-based studies are scarce, and most published data are from high-income countries, where the main cause of acute liver failure is paracetamol overdose. This Review provides an overview of the scanty literature on acute liver failure in low-income and middle-income countries, where patients are often admitted to primary care hospitals and viral hepatitis (especially hepatitis E), tropical infections (eg, dengue), traditional medicines, and drugs (especially anti-tuberculosis drugs) have an important role. We discuss incidence, cause, occurrence in children and pregnant women, prognostic factors and scores, treatment, and mortality. To conclude, we advocate for international collaboration, the establishment of central registries for the condition, and better diagnostics.

Abstract
BACKGROUND/OBJECTIVES Acute liver failure (ALF) is rare and associated with poor outcomes. The outcomes of ALF and predictors of outcome may vary as per the etiology. There are limited data on the predictors of spontaneous survival among patients with ALF of non-A-E hepatitis or cryptogenic etiology. We aimed to assess clinical course, complications, and outcome of non-A-E etiology ALF. METHODS In this prospective analysis, all consecutive ALF patients (n = 1555; January 1986-June 2018) were analyzed. Non-A-E-ALF was defined as ALF that could not be attributed to known etiologies such as drugs, viral hepatitis, autoimmune hepatitis, and Wilson's disease. Clinical course, complications, and outcomes of non-A-E-ALF patients who did not undergo liver transplantation were analyzed. Unadjusted and adjusted odds ratios (ORs) were calculated. RESULTS Non-A-E-ALF constituted 34.6% (n = 538) of all ALF patients, whereas hepatitis E virus (HEV), hepatitis B virus (HBV), and anti-tuberculosis therapy (ATT) accounted for 29.5% (n = 459), 8.6% (n = 134), and 7.4% (n = 115), respectively. Among non-A-E-ALF patients, mean age was 28.8 ± 12.0 years, 50.9% females, majority (63.1%) had hyperacute presentation, and 79.2% had advanced encephalopathy at presentation. The frequency of cerebral edema in non-A-E-ALF (53.3%) was higher than that in HEV-ALF (41.2%) and ATT-ALF (44.2%), P < 0.001. The survival rate in non-A-E-ALF (37.5%) was poorer than HEV-ALF (54.9%) and was comparable to that in HBV (35.8%) and ATT (29.6%) induced ALF. The baseline prothrombin time prolongation (odds ratio [OR] 1.041; 95% confidence intervals [CI], 1.017-1.065) and infection (OR 2.366; 95%CI, 1.107-5.055) were independent predictors of outcome in non-A-E-ALF. The 3-days acute liver failure early dynamic model had the best value in predicting the outcome. CONCLUSIONS Non-A-E-ALF accounts for one-third of all cases of ALF and is associated with poor spontaneous survival.

Abstract
INTRODUCTION AND AIM Multiple prognostic scores are available for acute liver failure (ALF). Our objective was to compare the dynamicity of model for end stage liver disease (MELD), MELD-sodium, acute liver failure early dynamic model (ALFED), chronic liver failure (CLIF)-consortium ACLF score and King's College Hospital Criteria (KCH) for predicting outcome in ALF. MATERIALS AND METHODS All consecutive patients with ALF at a tertiary care centre in India were included. MELD, MELD-Na, ALFED, CLIF-C ACLF scores and KCH criteria were calculated at admission and day 3 of admission. Area under receiver operator characteristic curves (AUROC) were compared with DeLong method. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), likelihood ratio (LR) and diagnostic accuracy (DA) were reported. RESULTS Of the 115 patients included in the study, 73 (63.5%) died. The discrimination of mortality with baseline values of prognostic scores (MELD, MELD-Na, ALFED, CLIF-C ACLF and KCH) was modest (AUROC: 0.65-0.77). The AUROC increased on day 3 for all scores, except KCH criteria. On day 3 of admission, ALFED score had the highest AUROC 0.95, followed by CLIF-C ACLF 0.88, MELD 0.81, MELD-Na 0.77 and KCH 0.52. The AUROC for ALFED was significantly higher than MELD, MELD-Na and KCH (P < 0.001 for all) and CLIF-C ACLF (P = 0.05). ALFED score ≥ 4 on day 3 had the best sensitivity (87.1%), specificity (89.5%), PPV (93.8%), NPV (79.1%), LR positive (8.3) and DA (87.9%) for predicting mortality. CONCLUSIONS Dynamic assessment of prognostic scores better predicts outcome. ALFED model performs better than MELD, MELD, MELD-Na, CLIF-C ACLF scores and KCH criteria for predicting outcome in viral hepatitis- related ALF.

Abstract
BACKGROUND Acute on chronic liver failure (ACLF) is associated with high short term mortality. We aimed to evaluate the prevalence, predictors and impact of bacterial infection in ACLF. METHODS Consecutive hospitalized patients with cirrhosis and acute decompensation (AD), from January 2011-March 2017, were included. Predictors of survival and infection were assessed. RESULTS 572 patients with cirrhosis and AD were classified into 3 groups - no infection (group 1, n = 190, 33.2%), infection at admission/within 48 h (group 2, n = 298, 52.1%) and infection after 48 h (group 3, n = 84, 14.7%). Higher frequency of organ failures - kidney, brain, circulation and respiratory failure - were seen in groups 2 and 3 as compared with group 1 (P < 0.001 for all). Most common site of infection was lungs, followed by spontaneous bacterial peritonitis and urinary tract infection. The frequency of infection increased with higher ACLF grades. Among ACLF patients, on Cox-proportional multivariate analysis, presence of infection was associated with significantly higher mortality [group 2 (HR 2.93; 95%CI, 1.97-4.38, P < 0.001) and group 3 (HR 1.84; 95%CI, 1.16-2.91, P = 0.009)], as compared with group 1. On multivariate logistic regression analysis, advanced hepatic encephalopathy and elevated total leucocyte count were independently associated with development of infection. CONCLUSIONS Infections are common in ACLF, and associated with poor outcome.

Abstract
INTRODUCTION AND AIM Patients with acute on chronic liver failure (ACLF) have abnormal conventional coagulation tests- platelet count and international normalized ratio (INR). Thromboelastography (TEG) is a rapid, point-of-care assay, more comprehensive than platelet count and INR as it assesses for platelet adequacy (number and function), coagulation factors and clot retraction. The aim of the study was to evaluate the TEG parameters in patients with ACLF, chronic liver disease having acute decompensation (AD) and healthy subjects (HC). MATERIAL AND METHODS TEG parameters were assessed in patients with ACLF and AD within 24 h of admission. Consecutive patients were included in the study over 12 months. Healthy subjects were recruited as controls. RESULTS 179 patients were included- 68 ACLF, 53 AD and 58 HC. The mean values of INR in ACLF, AD and HC groups were 2.9 ± 1.4, 1.6 ± 0.4 and 1.1 ± 0.2; P < 0.001. Among TEG parameters - maximum amplitude (MA) was low in ACLF and AD patients as compared with HC (53.8 ± 15, 58.3 ± 13.9 mm and 67.2 ± 12.1 mm, respectively; P < 0.001). Lysis at 30 min (LY30) was high in ACLF patients, as compared to AD and HC (8.6 ± 14.1%, 5.0 ± 9.5% and 4.9 ± 9.8%, respectively; P = 0.060). There were no differences in r time, k time, and alpha angle between groups; normal in >90% patients. There was no difference in TEG parameters between different ACLF grades, whereas CCTs were more deranged with increasing grades of ACLF. CONCLUSION Despite abnormal conventional coagulation tests, TEG parameters in ACLF patients are essentially normal, except reduced maximum amplitude. Future studies are needed to explore the utility of TEG in clinical management of ACLF patients.

Abstract
BACKGROUND AND AIMS Various prognostic scores are available for predicting outcome in acute-on-chronic liver failure (ACLF). We compared the available prognostic models as predictors of outcome in alcohol-related ACLF patients. METHODS All consecutive patients with alcohol-related ACLF were included. At admission, prognostic indices-acute physiology and chronic health evaluation score (APACHE II), model for end-stage liver disease (MELD), MELD-Na, Maddrey's discriminant function (DF), age-bilirubin-INR-creatinine (ABIC), and Chronic Liver Failure Consortium (CLIF-C) ACLF score (CLIF-C ACLF) score were calculated. Receiver operator characteristic (ROC) curves were plotted for all prognostic scores with in-hospital, 90-day, and 1-year mortality as outcome. RESULTS Of the 171 patients, 170 were males, and grade 1 ACLF in 20 (11.7%), grade 2 in 52 (30.4%), and grade 3 in 99 (57.9%) patients. One hundred and nineteen (69.6%) died in-hospital. The median (IQR) Maddrey's score, MELD, MELD-Na, ABIC, APACHE II, and CLIF-C ACLF were 87.8 (66.5-123.0), 33.1 (27.6-40.0), 34.4 (29.5-40.0), 8.5 (7.3-9.6), 15 (12-21), and 51.1 (44.1-56.4), respectively. On multivariate Cox regression analysis, independent predictors of in-hospital outcome were presence of hepatic encephalopathy (early HR, 2.078; 95%CI, 1.173-3.682, p = 0.012 and advanced, HR, 2.330; 95% CI, 1.270-4.276, p = 0.006), elevated serum creatinine (HR, 1.140; 95% CI, 1.023-1.270, p = 0.018), and infection at admission (HR, 1.874; 95% CI, 1.160-23.029, p = 0.010). On comparison of ROC curves, APACHE II and CLIF-C ACLF AUROC were significantly higher than MELD, MELD-Na, DF, and ABIC (p < 0.05) for predicting in-hospital, 90-day, and 1-year mortality. The AUROC was highest for APACHE II followed by CLIF-C ACLF (Hanley and McNeil, p = 0.660). CONCLUSIONS Alcohol-related ACLF has high in-hospital mortality. Among the available prognostic scores, CLIF-C ACLF and APACHE II perform best.

Abstract
OBJECTIVE Infections are common and associated with complications and mortality in acute liver failure (ALF). The temporal relationship between ammonia and infection in ALF patients is unclear. We aimed to evaluate the predictors of infection and its relationship with arterial ammonia levels. MATERIALS AND METHODS Consecutive ALF patients hospitalized between January 2004 and December 2015, without signs of infection at/within 48 h of admission, were included. Occurrence of infection after 48 h was documented and ammonia levels were estimated for five consecutive days. Multivariate logistic regression analysis was used to assess factors associated with development of infection. Generalized estimating equations (GEE) were used to evaluate five-day time trend of ammonia in patients with and without infection. RESULTS Of 540 consecutive patients, 120 were infected at admission/within 48 h and were excluded. Of the rest 420 patients, 144 (34.3%) developed infection after 48 h and 276 (65.7%) remained non-infected. Infected patients had higher mortality than non-infected patients (61.8% vs 40.0%, p < .001). On multivariate analysis, presence of cerebral edema(HR 2.049; 95%CI, 1.30-3.23), ammonia level on day 3 of admission (HR 1.006; 95%CI, 1.003-1.008), and model for end stage liver disease (MELD) score (HR 1.051; 95%CI, 1.026-1.078) were associated with development of infection. GEE showed group difference in serial ammonia values between infected and non-infected patients indicating lack of ammonia decline in infected patients. CONCLUSIONS Cerebral edema, elevated ammonia on day 3, and higher MELD score predict the development of infection in ALF. Ammonia persists at high levels in infected patients, and elevated ammonia on day 3 is associated with complications and death.

Abstract
BACKGROUND Acute-on-chronic liver failure (ACLF) may be precipitated by various hepatic insults. The present study evaluated the outcomes of ACLF with different acute insults. PATIENTS AND METHODS A total of 368 ACLF patients were included. Data collected included etiologies of acute hepatic insult and underlying chronic liver disease, and organ failure. Model for end-stage liver disease (MELD), chronic liver failure consortium (CLIF)-C ACLF, and acute physiology and chronic health evaluation (APACHE) II scores were calculated. Predictors of survival were assessed by the Cox proportional hazard model. RESULTS The most frequent acute insult was active alcohol consumption [150 (40.8%) patients], followed by hepatitis B virus (HBV) [71 (19.3%) patients], hepatitis E virus (HEV) superinfection [45 (12.2%) patients], autoimmune hepatitis flare [17 (4.6%) patients], antituberculosis drugs [16 (4.3%) patients], and hepatitis A virus superinfection [2 (0.5%) patients]; 67 (18.2%) cases were cryptogenic. Alcohol-ACLF and cryptogenic-ACLF were more severe. Median CLIF-C, MELD, and APACHE II scores in alcohol-ACLF and cryptogenic-ACLF were significantly higher than those in HBV-ACLF and HEV-ACLF (CLIF-C: 47.1, 47.4 vs. 42.9, 42.0, P=0.002; MELD: 29, 29.9 vs. 28.9, 25.2, P=0.02; APACHE II: 16.5, 18.0 vs. 12, 14, P<0.001, respectively). Frequencies of kidney and brain failures were also higher in alcohol/cryptogenic-ACLF than in HBV/HEV-ACLF (kidney failure: 35.3%/34.3% vs. 23.9%/11.1%, P=0.009; brain failure: 26.0%/22.4% vs. 15.5%/4.4%, P=0.01, respectively). Mortality in the alcohol-ACLF group was the highest (64.0%), followed by that in the cryptogenic-ACLF (62.7%), HBV-ACLF (45.1%), and HEV-ACLF (17.8%) groups (P<0.001). In multivariable analysis, alcohol-ACLF had significantly higher mortality compared with HEV-ACLF (hazard ratio, 3.06; 95% confidence interval, 1.10-8.49, P=0.03). CONCLUSIONS Alcohol/cryptogenic-ACLF had more severe phenotypic presentation, more incidence of organ failures, and higher mortality compared with HEV/HBV-ACLF. Alcohol-ACLF had the highest mortality, whereas HEV-ACLF had the best survival.

Abstract
BACKGROUND AND AIM Hepatitis E virus (HEV) is a global disease and an important cause of acute liver failure (ALF) in the Indian subcontinent. The aim of this study was to assess the differences in the course of HEV-ALF as compared to other etiologies of ALF. METHODS We compared the clinical course, complications, and outcomes of HEV-ALF with other etiologies. We assessed the prognostic factors and compared existing prognostic scores in HEV-ALF patients. RESULTS One thousand four hundred and sixty-two ALF patients were evaluated between January 1986 and December 2015. HEV was the etiology of ALF in 419 (28.7%) cases, whereas non-A non-E hepatitis, HBV and anti-tuberculosis therapy (ATT) were the etiologies in 527 (36.0%), 128 (8.8%), and 103 (7.0%) cases, respectively. The frequency of cerebral edema in HEV-ALF (41.3%) was lower than that in non-A non-E ALF (52.9%; P < 0.001) and HBV-ALF (52.8%; P = 0.024). Infection and seizures were significantly less in patients with HEV-ALF compared to non-A non-E and HBV-ALF (P = 0.038 and 0.022, respectively). The survival of HEV-ALF patients was significantly better (55.1%, P < 0.001) than patients of other etiologies-including ATT (30.0%), non-A non-E (38.1%) and HBV (35.9%). In HEV-ALF patients, age, female sex, cerebral edema, prothrombin time >60 s, infection, and total bilirubin were observed as independent predictors of outcome on multivariate logistic regression analysis. Model for end-stage liver disease, acute liver failure study group model and King's College Hospital criteria had poor discriminative accuracy for outcome (area under receiver operator characteristic curve 0.63-0.64) in HEV-ALF. CONCLUSIONS Hepatitis E virus-associated ALF has a better outcome than ALF of other etiologies.

Abstract
The sudden failure of a previously healthy and functioning liver is a dramatic and devastating event. Acute liver failure is the common final pathway of a multitude of conditions and insults, all of which result in massive hepatic necrosis or loss of normal hepatic function. The ensuing multiorgan system failure frequently has a fatal outcome, with mortality rates in most series ranging from approximately 55% to 95% [1]. Acute liver failure (ALF, previously often referred to as fulminant hepatic failure (FHF)) knows no age boundaries, with many cases occurring in those younger than 30 years. Short of excellent intensive care unit (ICU) support and liver transplantation in selected cases, few viable treatment options are available. Over the past few decades, however, survival has been improved by anticipation, recognition, and early treatment of associated complications, as well as the application of prognostic criteria for early identification of patients requiring liver transplantation (along with improvement in the techniques and science of transplantation itself). The etiology of ALF varies from country to country and the incidence change over time. Paracetamol (acetaminophen) has now replaced viral hepatitis as the leading cause of ALF [2]. In a study from London including 310 patients with ALF in the period 1994–2004, 42% of the cases were caused by paracetamol [3], whereas this was only the cause in 2% of 267 patients in Spain from 1992 to 2000 [4]. However, less than 10% of all liver transplants are performed in patients with ALF [5, 6].

Abstract
BACKGROUND AND AIM Acute on chronic liver failure (ACLF) because of precipitating factors (variceal bleed/infections) identifies cirrhotics at risk for high short-term mortality. Information on ACLF because of acute hepatic insults is lacking. The aim of the study was to evaluate acute hepatic insults in ACLF and their effect on the course and outcome. METHODS In a prospective study, 213 consecutive patients of ACLF because of acute hepatic insults were included. Etiology of acute hepatic insult, frequency of silent, and overt chronic liver disease (CLD), organ failure (OF), and outcomes were assessed. Prognostic models such as model for endstage liver disease (MELD), acute physiology and chronic health evaluation (APACHE II), and chronic liver failure-sequential organ failure (CLIF-SOFA) were evaluated. RESULTS Etiologies of acute hepatic insult were hepatitis virus(es)- 81 (38%; HBV-42, HEV-39), continuous alcohol consumption-77 (33.3%), antituberculosis drugs-11 (5.2%), autoimmune hepatitis flare-5(2.3%), cryptogenic-44 (20.7%). The common causes of CLD were alcohol (n = 85/40%), HBV(n = 52/24%), and cryptogenic(n = 50/20%). The MELD, APACHE II, and CLIF-SOFA scores were similar among silent and overt CLD and did not influence outcome. Predominant etiologies of ACLF were hepatitis virus(es) reactivation or superinfection in silent CLD(52/112, 46.4%) and alcohol among overt CLD(43/101, 43%). Independent predictors of mortality included hepatic-encephalopathy (early, HR: 4.01; advanced, HR: 6.10), serum creatinine ≥1.5 mg/dl (HR: 4.53), CLIF-SOFA ≥8(HR: 1.69), and etiology of acute hepatic insult (alcohol, HR: 4.08; cryptogenic, HR: 3.18). HEV-ACLF had lower mortality (12.8% vs. 33-54% in other etiologies;P < 0.001). OF was major determinant of mortality. With increasing number of OF, mortality increased linearly(P = 0.001). CONCLUSIONS Hepatitis virus(es) and continuous alcohol consumption are important causes of ACLF caused by acute hepatic insults. HEV-ACLF has lower mortality. OF is an important prognostic predictor.

Abstract
Objectives: Thyroid storm is a presentation of severe thyrotoxicosis that has a mortality rate of up to 20% to 30%. Fulminant hepatic failure (FHF) entails encephalopathy with severe coagulopathy in the setting of liver disease. It carries a high mortality rate, with an approximately 60% rate of overall survival for patients who undergo orthotopic liver transplantation (OLT). Fulminant hepatic failure is a rare but serious complication of thyroid storm. There have been only 6 previously reported cases of FHF with thyroid storm. Methods: We present a patient from our institution with thyroid storm and FHF. A literature review was performed to analyze the outcomes of the 6 additional cases of concomitant thyroid storm and FHF. Results: Our patient underwent thyroidectomy followed by OLT. Her serum levels of thyroid-stimulating hormone, triiodothyronine, thyroxine, and transaminase normalized, and she was ready for discharge within 10 days of surgery. She has survived without complication. There is a 40% mortality rate for the reported patients treated medically with these conditions. Of the 7 total cases of reported FHF and thyroid storm, 2 patients died. Only 2 of the 7 patients underwent thyroidectomy and OLT — Both at our institution. Both patients survived without complications. Conclusions: Thyroid storm and FHF each independently carry high mortality rates, and managing patients with both conditions simultaneously is an extraordinary challenge. These cases should compel clinicians to investigate liver function in hyperthyroid patients and to be wary of its rapid decline in patients who present in thyroid storm with symptoms of liver dysfunction. Patients with rapidly progressing thyroid storm and FHF should be considered for total thyroidectomy and OLT.

Abstract
UNLABELLED Antituberculosis therapy (ATT)-associated acute liver failure (ATT-ALF) is the commonest drug-induced ALF in South Asia. Prospective studies on ATT-ALF are lacking. The current study prospectively evaluated the magnitude, clinical course, outcome, and prognostic factors in ATT-ALF. From January 1986 to January 2009, 1223 consecutive ALF patients were evaluated: ATT alone was the cause in 70 (5.7%) patients. Another 15 (1.2%) had ATT and simultaneous hepatitis virus infection. In 44 (62.8%) patients, ATT was prescribed empirically without definitive evidence of tuberculosis. ATT-ALF patients were younger (32.87 [+/-15.8] years), and 49 (70%) of them were women. Most had hyperacute presentation; the median icterus encephalopathy interval was 4.5 (0-30) days. The median duration of ATT before ALF was 30 (7-350) days. At presentation, advanced encephalopathy and cerebral edema were present in 51 (76%) and 29 (41.4%) patients, respectively. Gastrointestinal bleed, seizures, infection, and acute renal failure were documented in seven (10%), five (7.1%), 26 (37.1%), and seven (10%) patients, respectively. Compared with hepatitis E virus (HEV) and non-A non-E-induced ALF, ATT-ALF patients had nearly similar presentations except for older age and less elevation of liver enzymes. The mortality rate among patients with ATT-ALF was high (67.1%, n = 47), and only 23 (32.9%) patients recovered with medical treatment. In multivariate analysis, three factors independently predicted mortality: serum bilirubin (>or=10.8 mg/dL), prothrombin time (PT) prolongation (>or=26 seconds), and grade III/IV encephalopathy at presentation. CONCLUSION ATT-ALF constituted 5.7% of ALF at our center and had a high mortality rate. Because the mortality rate is so high, determining which factors are predictors is less important. A high proportion of patients had consumed ATT empirically, which could have been prevented.

Gastroenterology 2009; 136:2159-68. [PMID: 19505424 DOI: 10.1053/j.gastro.2009.02.050] [Citation(s) in RCA: 116] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2008] [Revised: 01/09/2009] [Accepted: 02/10/2009] [Indexed: 12/20/2022]
Abstract
BACKGROUND & AIMS In acute liver failure (ALF), high blood ammonia levels have been documented that correlate with mortality and complications. L-ornithine L-aspartate (LOLA) reduces ammonia levels by increasing hepatic ammonia disposal and its peripheral metabolism. Present study evaluated efficacy and ammonia lowering effect of LOLA in ALF. METHODS This study was placebo-controlled and blinded. We randomized 201 patients with ALF between January 2005 and October 2007 to either placebo or LOLA infusions (30 g daily) for 3 days. Arterial ammonia was measured at baseline and daily for 6 days. The primary end point was improvement in survival. The study followed CONSORT guidelines and was registered at the ClinicalTrials.gov (Identifier: NCT00470314). RESULTS There was no reduction in mortality with LOLA treatment (mortality: 33.3% in placebo and 42.4% in LOLA; relative risk of death 1.27; 95% CI: 0.88-1.85; P = .204). By multivariate analysis, ammonia levels were an independent predictor of survival. There was significant decrease in ammonia levels in both groups with time (P < .001), but the levels of ammonia between the randomized groups at any time point, either during the 72 hours of LOLA infusion or during the follow-up were similar (P = .492). There was no difference between the 2 groups in the improvement in encephalopathy grade (P = .418), consciousness recovery time (P = .347), survival time (P = .612), or complications like seizures (P = .058) and renal failure (P = .615). The fetal outcome was also similar (P = .172). No adverse drug effect was noted. CONCLUSIONS LOLA infusion did not lower the ammonia or improved survival in ALF.

Abstract
UNLABELLED Pregnant patients with acute liver failure (ALF) are believed to have a worse outcome than nonpregnant women and men with ALF. However objective data supporting this supposition are scant. Therefore, the current study compared the outcome, complications, and causes of ALF among pregnant women and girls with age-matched nonpregnant women and girls and men and boys with ALF. One thousand fifteen consecutive ALF patients in the reproductive age group, admitted at the All India Institute of Medical Sciences, New Delhi, from January 1986 to December 2006, were included in the study. A total of 249 (38.5%) women were pregnant. They were compared with 341 nonpregnant women and girls and 425 men and boys, aged 15 to 45 years. The mortality rate of pregnant women and girls (53.8%) was similar to age-matched nonpregnant women and girls (57.2%), and men and boys (57.9%); P = 0.572. The clinical and biochemical features, disease severity, and complications were also similar in the three groups. A significantly higher proportion of ALF was attributable to hepatitis E virus (HEV) among women and girls who were pregnant (59.4%), as compared with both nonpregnant women and girls (30.4%), and men and boys (23.1%); P < 0.001. However, the outcome of HEV-related ALF was independent of the sex and pregnancy status of the patients (P = 0.103). Mortality in HEV-ALF and non-HEV-ALF patients in pregnant women and girls was 51% (74/145) and 54.7% (52/95)(P > 0.1), respectively. The outcome of pregnant ALF patients was also unrelated to the trimester of pregnancy. The mortality of non-HEV-related ALF among the pregnant women and girls (54.7%), age-matched nonpregnant women and girls (61.7%), and men and boys (62.8%) were also similar (P > 0.1). CONCLUSION The mortality of pregnant patients with ALF is similar to that of nonpregnant women and girls and men and boys and is independent of the cause or trimester. Pregnancy per se should not be regarded as a poor prognostic factor for a patient with ALF.

Abstract
PURPOSE Acute liver failure (ALF) is characterized by a rapid and massive destruction of hepatocytes. The role of oxidative stress in perpetuating the injury is undefined and may be a potential therapeutic target. Our aim was to study serial variation in oxidative stress and antioxidant status in patients with ALF. METHODS The study involved a prospective case-control study set in a tertiary care referral center. Thirty-two consecutive patients admitted with ALF were included with 23 healthy controls for comparison. Level of systemic oxidative stress as defined by superoxide dismutase (SOD), lipid peroxidation products (thiobarbituric acid reactive derivatives [TBARS]), and the total antioxidant capacity as the ferric reducing ability of plasma (FRAP) was measured at baseline on days 3 and 7. RESULTS The patients were aged 24 years (range 13-60 years) and included 20 females. Thirteen (40.6%) patients died. Patients with ALF had significantly increased systemic oxidative stress at presentation, as reflected by higher levels of SOD (P < 0.001) and TBARS (P < 0.001) than controls. Both TBARS levels and FRAP decreased progressively from admission to the end of first week among the survivors (P = 0.004 and 0.015, respectively). The antioxidant status reflected by FRAP (P = 0.001) was significantly lower in ALF patients than controls. No relation was found between the level of oxidative stress and the mortality or complications. CONCLUSION A high level of systemic oxidative stress exists in ALF, with depletion of antioxidant reserves. Further studies are needed to define the clinical correlation of the large pro-oxidant burden.

Abstract
OBJECTIVE To identify clinical and laboratory features of patients with malarial hepatitis simulating fulminant hepatic failure (MHsFHF) and distinguish it from viral FHF. PATIENTS AND METHODS At a tertiary care unit in Bangalore, India, we compared clinical and laboratory characteristics of 25 patients with MHsFHF with those of 25 patients with viral FHF from November 1996 to January 2000. RESULTS No statistically significant differences were seen in duration of jaundice, altered consciousness, and the interval between onset of jaundice and altered consciousness between the 2 groups. Hepatomegaly and splenomegaly were present in 72% and 48% of patients with MHsFHF and in 12% and 0% of patients with viral FHF (P<.001), respectively. The MHsFHF group had a significantly lower hemoglobin level (9.3 g/dL vs 12.9 g/dL), total leukocyte count (9.1 x 10(9)/L vs 18 x 10(9)/L), platelet count (44.8 x 10(9)/L vs 218.6 x 10(9)/L), and transaminases (alanine aminotransferase, 86.2 U/L vs 1230.0 U/L; aspartate aminotransferase, 131.9 U/L vs 720.0 U/L) (P<.001). Thrombocytopenia and elevated serum urea nitrogen were universal in patients with MHsFHF. Prothrombin time was abnormal in all patients with viral FHF and in only 1 patient with MHsFHF. Of patients with MHsFHF, 24% died; of patients with viral FHF, 76% died (P=.02). CONCLUSIONS In endemic areas, severe malaria should be considered in the differential diagnosis of FHF. Hepatomegaly and normal prothrombin time in the setting of FHF are suggestive of malaria, and a peripheral blood smear should be obtained for diagnostic confirmation.

Abstract
To investigate the role of hepatitis B virus (HBV) infection in pediatric fulminant hepatic failure (FHF) after the launch of universal HBV vaccination, the authors analyzed the data from patients with FHF collected from a nationwide collaborative study group. Children aged 1 month to 15 years who were diagnosed with FHF (62 males and 33 females) between 1985-1999 were included. HBV infection (hepatitis B surface antigen [HBsAg] and/or immunoglobulin M hepatitis B core antibody [IgM anti-HBc] seropositive) accounted for 46% (43 of 95 cases) of all the cases of FHF. The average annual incidence of FHF in the time period 1985-1999 was 0.053/100,000 in the group of patients ages 1-15 years and 1.29/100,000 in those patients age < 1 year. Approximately 61% (58 of 95 cases) of all FHF cases were infants. The percentage of HBV infection was found to be higher in infants (57%) compared with children ages 1-15 years (27%) (P = 0.004). The incidence rate ratio of those patients age < 1 year to those ages 1-15 years was 54.2 for HBV-positive FHF and 15.2 for HBV-negative FHF. Maternal HBsAg was found to be positive in 97% of the infants with HBV-positive FHF, and hepatitis B e antigen (HBeAg) was found to be negative in 84% of these infants. Approximately 74% of all HBV-positive FHF patients and 81% of the infantile HBV-positive patients had been vaccinated. In conclusion, within the first 15 years of universal vaccination, HBV was found to rarely cause FHF in children age > 1 year but remained a significant cause of FHF in infants. HBV-positive FHF was prone to develop in infants born to HBeAg-negative, HBsAg-carrier mothers; these infants had not received hepatitis B immunoglobulin according to the vaccination program in place.

Abstract
We report a case of an adult female who developed fulminant hepatic failure (FHF) during the second trimester of pregnancy and underwent a successful living related liver transplantation because no cadaveric donor was available during the development of life-threatening symptoms. A left lateral segment hepatic graft was procured from her brother, whose body weight was similar to hers. Her postoperative course was complicated by bleeding at the biliary anastomosis and subsequently by a biliary leak. Nevertheless, the complications were corrected surgically and the patient recovered well with a good quality of life 5 months after the transplant. This case suggests that living related liver transplantation should be considered more frequently for adult FHF patients. As the window of therapeutic opportunity is narrow for the dramatic condition of FHF, wide acceptance of this procedure will be of great benefit for the patients suffering from FHF.

Abstract
Hepatitis is a diagnosis that can easily be missed by the physician. The morbidity of this disease is significant when one takes into account all the cases that either do not have a typical presentation or are misdiagnosed. The emergency physician bears substantial responsibility in the diagnosis and intervention of patients with hepatitis, and needs to develop a systematic way of approaching the patient with a viral syndrome or other vague complaints that will allow appropriate consideration of this diagnosis.

Abstract
Gc-globulin scavenges actin released from necrotic hepatocytes to the extracellular space. In 77 patients with fulminant hepatic failure (FHF) (excluding patients treated with liver transplantation), admission levels of serum Gc-globulin and degree of complexing with monomeric actin (complex ratio) were determined to evaluate their predictive values in relation to survival/nonsurvival. Gc-globulin levels were significantly reduced in 47 nonsurvivors, compared with 30 survivors (96 +/- 71 mg/L vs. 169 +/- 101 mg/L, P < .001), whereas the complex ratio in nonsurvivors did not differ significantly from that of survivors. Gc-globulin levels were significantly lower in 59 patients with non-acetaminophen-induced FHF, compared with 18 patients with acetaminophen-induced FHF (P < .01). Using a cutoff level of serum Gc-globulin of 100 mg/L, a lesser value correctly predicted nonsurvival in 79 percent of patients with non-acetaminophen-induced FHF, whereas a higher value predicted survival in 60 percent. In patients with acetaminophen-induced FHF, nonsurvival was correctly predicted in 100 percent of patients and survival in 53 percent. In comparison, the King's College Hospital (KCH) criteria correctly predicted nonsurvival and survival in 69 percent and 57 percent, respectively, of the same non-acetaminophen-induced FHF patients and in 60 percent and 38 percent, respectively, of the acetaminophen-induced FHF patients. Thus, in our study population, the predictive properties of Gc-globulin were in the same range as the KCH criteria. An advantage of Gc-globulin is that it gives an estimate of the outcome already on admission. Acute liver transplantation should be considered in FHF patients with Gc-globulin less than 100 mg/L.
