A tromboelastometria identifica coagulopatia associada à insuficiência hepática e coagulação intravascular disseminada causadas por febre amarela, orientando a terapia hemostática específica: um relato de caso / Thromboelastometry identifies coagulopathy associated with liver failure and disseminated intravascular coagulation caused by yellow fever, guiding specific hemostatic therapy: a case report

RESUMO Este relato de caso detalha um caso grave de febre amarela complicada por insuficiência hepática e coagulação intravascular disseminada. A tromboelastometria foi capaz de identificar os distúrbios da coagulação e orientar o tratamento hemostático. Relatamos o caso de um homem com 23 anos de idade admitido na unidade de terapia intensiva com quadro com início abrupto de febre e dor muscular generalizada associados a insuficiência hepática e coagulação intravascular disseminada. Os resultados dos exames laboratoriais convencionais revelaram trombocitopenia, enquanto a tromboelastometria sugeriu coagulopatia com discreta hipofibrinogenemia, consumo de fatores de coagulação e, consequentemente, aumento do risco de sangramento. Diferentemente dos exames laboratoriais convencionais, a tromboelastometria identificou o distúrbio de coagulação específico e, assim, orientou o tratamento hemostático. Administraram-se concentrados de fibrinogênio e vitamina K, não sendo necessária a transfusão de qualquer componente do sangue, mesmo na presença de trombocitopenia. A tromboelastometria permitiu a identificação precoce da coagulopatia e ajudou a orientar a terapêutica hemostática. A administração de fármacos hemostáticos, incluindo concentrados de fibrinogênio e vitamina K, melhorou os parâmetros tromboelastométricos, com correção do transtorno da coagulação. Não se realizou transfusão de hemocomponentes, e não ocorreu qualquer sangramento.

Abstract This case report a severe case of yellow fever complicated by liver failure and disseminated intravascular coagulation. Thromboelastometry was capable of identifying clotting disorders and guiding hemostatic therapy. We report the case of a 23-year-old male admitted to the Intensive Care Unit with sudden onset of fever, generalized muscle pain associated with liver failure, and disseminated intravascular coagulation. The results of conventional laboratory tests showed thrombocytopenia, whereas thromboelastometry suggested coagulopathy with slight hypofibrinogenemia, clotting factor consumption, and, consequently, an increased risk of bleeding. Unlike conventional laboratory tests, thromboelastometry identified the specific coagulation disorder and thereby guided hemostatic therapy. Both fibrinogen concentrates and vitamin K were administered, and no blood component transfusion was required, even in the presence of thrombocytopenia. Administration of hemostatic drugs, including fibrinogen concentrate and vitamin K, improved thromboelastometric parameters, correcting the complex coagulation disorder. Blood component transfusion was not performed, and there was no bleeding.

Manifestaciones cutáneas de enfermedades gastrointestinales / Cutaneous manifestations of gastrointestinal diseases

The gastrointestinal system is closely related to the skin. Multiple disorders of the gastrointestinal tract that manifest clinically on the skin surface are recognized, which can even occur before establishing the definitive diagnosis of the disease. For this reason, it is necessary that the dermatologist is internalized regarding the wide variety of clinical signs that can guide the etiological study, which requires in most cases, a multidisciplinary management.

Histological and biochemical study on the protective effect of losartan on rat renal cortex in experimentally induced liver failure

Hepatic ischemia/reperfusion [I/R] injury is an unavoidable problem during liver surgery that often results in acute liver failure, with its complications. Losartan may be beneficial in such conditions. This study was designed to investigate the histological and biochemical alterations that could occur in the renal cortex in case of liver cell failure and to assess the possible protective role of losartan. Thirty male albino rats were equally divided into three groups: group I [control] was equally subdivided into sham operated-untreated [Ca] and sham-operated, losartan-treated [Cb] subgroups. In group II [operated], rats were subjected to experimentally induced I/R. In group III [losartan treated], rats were subjected to a surgical procedure and treated with losartan [5 mg/kg body weight]. At the end of the experiment, blood samples were obtained for the biochemical assay. The liver was processed for assessment of antioxidant markers and for light microscope examination. Both kidneys were processed for light and electron microscope examinations. The results were morphometrically and statistically analyzed. Light microscope examination of the operated group indicated shrunken glomeruli with wide Bowman's space. Some tubules were distorted with cytoplasmic vacuoles and cellular casts, whereas others were dilated. The interstitium contained an acidophilic material, increased collagen fibers, cellular infiltration, and congested blood vessels. Ultrastructurally, podocytes had small electron-dense nuclei and fused foot processes. Some renal tubules had small heterochromatic nuclei, mitochondria with disrupted cristae, and small electron-dense bodies. The biochemical results of the same group showed the occurrence of oxidative stress and deterioration in liver and kidney functions. The treated group showed preserved structure of the renal corpuscles and tubules. Liver I/R adversely affected the renal cortex histologically and biochemically. Losartan could be promising as an adjuvant therapy before hepatic surgery for rescuing the kidney from hepatic I/R injury

Experiencia argentina con pacientes positivos para el virus de la inmunodeficiencia humana en lista de espera para trasplante hepático: análisis preliminar / [The Argentine experience with human immune deficiency virus positive patients in the waiting list for liver transplantation: preliminary analysis].

UNLABELLED: After the introduction of high active antiretroviral therapy (HAART), the human immunodeficiency virus (HIV) was no longer considered a contraindication for transplantation. Yet, liver disease in this population is characterized by an accelerated course that may impact on the waiting list. OBJECTIVE: To evaluate the experience in Argentina with HIV positive patients listed for liver transplantation. PATIENTS AND METHODS: We analyzed 52 HIV positive patients listed between July 2005 and March 2010 (Group HIV positive). Results were compared with 462 HIV negative patients included during the same period (Group HIV negative). Data were obtained from INCUCAI, the Argentinian procurement organism and from the Transplantation Centers. RESULTS: The etiology of liver disease in the Group HIV positive was hepatitis C 40, HBV 3, fulminant hepatitis 3, alcohol 2, retrasplant 2 and others 2. The mean MELD at the time of listing was 1615 (lower than 19 in 40 cases, higher than 19 in 8, emergency in 3) in the group HIV positive and 16.64 in the group HIV negative (NS). The outcome in the waiting list for HIV positive and negative patients respectively was: death 14 (27

) (NS), mean time from listing to death 270.70 298.11 days vs 267.29 266.53 days (NS), mean time from listing to transplant 70.26 74.05 vs 261 187.6 days (P < 0.01), mean MELD at the time of death 12.54 (13 cases lower than 15, 1 higher than 19) vs 19.6 9.7 (P < 0.05), mean MELD at the time of transplantation 24.33 vs 24.1 7.6 (NS). CONCLUSION: HIV positive patients have high mortality in the waiting list and low access to liver transplantation. MELD score underscores the severity of liver disease in this population when compared to HIV negative patients.

Endocarditis infecciosa en pacientes con daño hepático crónico: Serie de 4 casos clínicos / Infective endocarditis in patients with chronic hepatic failure: A four cases series

Infective endocarditis and liver cirrhosis is an infrequent association. A retrospective study was performed in order to characterize predisposing factors, microbial causes and evolution. Medical records between 1995 and 2008 (June) were searched. Four cases were identified. In three cases liver cirrhosis was in stage Child A, and in all 4 there was a predisposing cardiac disease. Clinical manifestations were classical in 3 cases and in one presented as hepatic failure. Only in one case a typical agent was recovered. Other cases were associated to a nosocomial agent or Corynebacterium diphtheriae, and in one no agent was identified. One patient required valve replacement. Three patients recovered satisfactorily, all of them in Child A stage. One died of non-infectious causes (Child C). Infective endocarditis and liver cirrhosis is an infrequent association in clinical practice, it can be associated to unusual agents or clinical manifestations.

La asociación entre daño hepático y endocarditis infecciosa es infrecuente. Para analizar los factores predisponentes de esta asociación, la etiología microbiana y evolución clínica, se efectuó un análisis retrospectivo de los egresos por endocarditis infecciosa en pacientes con cirrosis hepática desde 1995 a junio de 2008. Se identificaron cuatro casos, asociados a categoría Child A en tres y en todos había una cardiopatía predisponente. Las manifestaciones clínicas fueron clásicas excepto en un caso que se presentó como descompensación hepática. Sólo un caso se asoció a un agente típico, otros a un agente nosocomial y Corynebacterium diphtheriae. En un caso no se identificó la etiología. Uno de los pacientes requirió cirugía de reemplazo valvular. Tres pacientes se recuperaron (Child A) y el paciente en categoría Child C falleció. Aunque infrecuente, la asociación cirrosis y endocarditis ocurre en la práctica clínica, se puede asociar a agentes inhabituales y tener manifestaciones encubiertas.

Reacción idiosincrásica fatal al propiltiouracilo / Fatal idiosyncratic reaction to propylthiouracilo

Se presenta una paciente con hipertiroidismo por una enfermedad autoinmune del tiroides que luego de 2 semanas de tratamiento con propiltiouracilo comenzó a presentar un rash generalizado acompañado de fiebre que evolucionó rápidamente a una insuficiencia hepática aguda, fallo multiorgánico y muerte. Se demostró en la necropsia la necrosis masiva del hígado. Se revisaron las afectaciones hepáticas inducidas por reacción idiosincrásicas a medicamentos. Se recomienda instruir a los pacientes sobre posibles síntomas de hepatotoxicidad, indicar pruebas hepáticas periódicamente a los hipertiroideos tratados con antitiroideos y evitar el uso simultáneo de fenobarbital.

The case of a patient with hyperthyroidism due to an autoimmune disease of the thyroid glands that after two weeks of treatment with propylthiouracil presented a systemic rash accompanied with fever evolving quickly to an acute hepatic failure, multiorgan failure, and death, was presenetd. A massive liver necrosis was confirmed in the necropsy. The hepatic affectations induced by idiosyncratic drug reaction were reviewed. We suggest to instruct these patients on the possible symptoms of hepatotoxicity, to indicate periodical hepatic tests to hyperthyroid patients treated with antithyroid agents, and to avoid the simultaneous use of phenobarbital.

Liver transplantion in a patient with rapid onset parkinsonism-dementia complex induced by manganism secondary to liver failure

Bilateral and symmetric globus-pallidus hyperintensities are observed on T1-weighted MRI in most of the patients with chronic liver failure, due to manganese accumulation. We report a 53-year-old man, with rapid onset parkinsonism-dementia complex associated with accumulation of manganese in the brain, secondary to liver failure. A brain MRI was performed and a high signal on T1-weighted images was seen on globus-pallidus, as well as on T2-weighted images on the hemispheric white-matter. He was referred to a liver-transplantation. The patient passed away on the seventh postoperative day. Our findings support the concept of the toxic effects of manganese on the globus-pallidus. The treatment of this form of parkinsonism is controversial and liver-transplantation should not be considered as first line treatment but as an alternative one.

Hiperintesidades simétricas e bilaterais dos gânglios da base são observadas em imagens de ressonância magnética encefálica (RM) ponderadas em T1 na maioria dos pacientes com insuficiência hepática crônica devidas ao acúmulo de manganês. Nós relatamos o caso de um homem, com 53 anos de idade, com um complexo parkinsonismo-demência rapidamente progressivo associado com o acúmulo de manganês no cérebro, secundariamente a insuficiência hepática. Uma RM encefálica foi realizada e foram observadas imagens hiperintensas/hipersinal nas imagens ponderadas em T1 no globo pálido e, também, na substância branca dos hemisférios cerebrais ponderadas em T2. Devido à falta de resposta ao tratamento clinico optamos pelo transplante hepático. O paciente faleceu no 7° dia de PO. Nossos achados corroboram o conceito dos efeitos tóxicos do manganês nos gânglios da base/globo pálido. O tratamento desta forma de parkinsonismo é controverso e o transplante hepático não deverá ser considerada uma opção terapêutica de primeira linha, porém como um tratamento alternativo considerando-se os riscos-benefícios dessa escolha.

Influência do grau de insuficiência hepática e do índice de congestão portal na recidiva hemorrágica de cirróticos submetidos a cirurgia de Teixeira-Warren / Role of liver function and portal vein congestion index on rebleeding in cirrhotics after distal splenorenal shunt

RACIONAL: A hipertensão portal com sua principal complicação, a hemorragia digestiva alta varicosa, são importantes causas de morbimortalidade em cirróticos. A cirurgia de Teixeira-Warren é uma derivação portal seletiva, adotada em doentes Child-Pugh A e B para tratamento da hemorragia varicosa por hipertensão portal não responsiva à terapêutica clínico-endoscópica após o quadro agudo. O índice de congestão portal baseia-se em valores obtidos pela ultra-sonografia Doppler abdominal e encontra-se elevado em pacientes com hipertensão portal. OBJETIVO: Verificar se o índice de congestão portal e o grau de insuficiência hepática (Child-Pugh) são fatores preditivos de recidiva hemorrágica após a cirurgia de Teixeira-Warren. MÉTODO: Em estudo longitudinal retrospectivo analisaram-se 62 prontuários de cirróticos operados pela técnica de Teixeira-Warren na Santa Casa de São Paulo. Foram submetidos a avaliação quanto ao índice de congestão portal pré-operatório 36 doentes, e 58 quanto à classe Child-Pugh. Os doentes foram divididos em grupos - com recidiva e ausência de recidiva hemorrágica - sendo analisada a diferença estatística quanto aos valores do índice e Child-Pugh pré-operatórios, relacionando-os à recidiva hemorrágica pós-operatória. RESULTADOS: Dos doentes que apresentaram recidiva hemorrágica, 69 por cento eram Child B e possuíam índice de congestão portal médio de 0,09. Já entre aqueles que não ressangraram, 62 por cento eram Child A e o índice de congestão portal médio foi de 0,076. A diferença foi estatisticamente significante para a classe Child-Pugh, porém, o mesmo não ocorreu para o índice de congestão portal. CONCLUSÃO: O índice de congestão portal no pré-operatório não foi fator preditivo de recidiva hemorrágica em cirróticos submetidos a cirurgia de Teixeira-Warren. Doentes classificados como Child-Pugh B possuem maior chance de recidiva hemorrágica pós-derivação esplenorrenal distal em relação aos Child-Pugh A.

BACKGROUND: Bleeding from esophagogastric varices is the worst and most lethal complication of cirrhotic portal hypertension. Distal splenorenal shunt (Warrens surgery) is used in the therapeutic of this patients, Child A and B, with rebleeding after clinical endoscopic therapy. The portal vein congestion index is elevated in cirrhotic portal hypertension and could predict rebleeding after Warrens surgery in these patients. AIM: To verify if the portal vein congestion index or liver function (Child-Pugh) at preoperative are predictive factors of rebleeding after Warrens surgery. METHODS: Sixty-two cirrhotic patients were submitted to Warrens surgery at "Santa Casa" Medical School and Hospital - Liver and Portal Hypertension Unit, São Paulo, SP, Brazil. Fifty-eight were analyzed for Child-Pugh class and 36 for portal vein congestion index, divided in two groups: with or without rebleeding and statistical analysis was performed. RESULTS: In the rebleeding group, 69 percent were Child B, with portal vein congestion index = 0.09. The group without rebleeding show us 62 percent patients Child A with portal vein congestion index = 0.076. The difference was significant for Child-Pugh class but not to portal vein congestion index. CONCLUSION: Portal vein congestion index was not predictive of rebleeding after Warrens surgery, but cirrhotics Child B have more chance to rebleed after this surgery than Child A.

The relationship between a model of end stage liver disease score (MELD score) and the occurrence of spontaneous bacterial peritonitis in liver cirrhotic patients.

AIM: To determine relationship between MELD score and the occurrence of SBP, prevalence of SBP, pattern of bacterial culture and antibiotic susceptibility of causative bacteria of liver cirrhotic patients at Sanglah Hospital. METHODS: Study design was a cross-sectional analytic study. The population in this study consists of liver cirrhotic patients admitted at Sanglah Hospital Denpasar from June 2005 to February 2006. RESULTS: This result confirmed that the MELD score is a reliable index of disease severity and that higher MELD scores had a significantly more frequent SBP prevalence in patients with a MELD score of 18 or more compared with that in patients with a MELD score of 17 or less (p=0.01; 95% CI = 1.379-15.537). Prevalence of SBP was 30.6%. Thirteen patients (68.4%) had monomicrobial positive culture of Aerob bacteria, consisting of Gram negative bacterias in 10 (77%), with Escherichia coli and Acinettobacter baumanii being the most frequent, and 3 (23%) had Gram positive bacteria. High sensitivity to Cefoperazone, Cefotaxim, Ceftazidime, Cefpirome, Ciprofloxacin, Fosfomicin, Meropenem, Streptomycin, Gentamycin, Trimethoprim/Sulphamethoxazole, were shown. CONCLUSION: Based on this study we concluded that severe liver cirrhosis with MELD score > or = 18 was associated with an increase risk of SBP, with a prevalence of 30.6%. Common causes of SBP mostly were Escherichia coli and Acinettobacter baumanii, which were sensitive to antibiotic treatment of Cefoperazone, Cefotaxime and Ciprofloxacin.

Liver cirrhosis and hepatic stellate cells / Cirrose hepática e células estreladas do figado

The cirrhosis represents the final stage of several chronic hepatic diseases and it is characterized by the presence of fibrosis and morphologic conversion from the normal hepatic architecture into structurally abnormal nodules. In the evolution of the disease there is loss of the normal vascular relationship and portal hypertension. There are also regenerative hepatocelular alterations that become more prominent with the progression of the disease. The liver transplantation continues to be the only therapeutic option in cases of disease in terminal phase. The hepatic stellate cells (HSC) are perisinusoidal cells that store vitamin A and produce growth factors, citocins, prostaglandins and other bioactive substances. They can suffer an activation process that convert them to cells with a phenotype similar to myofibroblasts. When activated, they present increased capacity of proliferation, mobility, contractility and synthesis of collagen and other components of extracelular matrix. They possess cytoplasmic processes adhered to sinusoids and can affect the sinusoidal blood flow. HSC are important in pathogenesis of fibrosis and portal hypertension.

A cirrose representa o estágio final de diversas doenças hepáticas crônicas e é caracterizada pela presença de fibrose e conversão da arquitetura hepática normal em nódulos estruturalmente anormais. Na evolução da doença ocorre perda da relação vascular normal e hipertensão portal. Há também alterações regenerativas hepatocelulares que se tornam mais proeminentes com a progressão da doença. O transplante hepático permanece como a única opção terapêutica nos casos de doença em fase terminal. As células estreladas hepáticas (CEH) são células perisinusoidais que armazenam vitamina A e produzem fatores de crescimento, citocinas, prostaglandinas e outras substâncias bioativas. Podem sofrer um processo de ativação para um fenótipo semelhante a miofibroblastos. Quando ativadas apresentam maior capacidade de proliferação, motilidade, contractilidade, síntese de colágeno e componentes da matriz extracelular. Possuem processos citoplasmáticos aderidos aos sinusóides e podem afetar o fluxo sangüíneo sinusoidal. As CEH são importantes na patogênese da fibrose e hipertensão portal.

there any relationship of age and sex to the etiology and outcome of medical coma?

As the diseases behave differently in males and females and even in different age groups, particular attention was made to classify and observe the distribution of various causes of coma according to age and sex of the patient in order to formulate our indigenous database for future reference. We studied the coma etiology with particular reference to the age and sex of the patient, and the outcome. All the 517 [312 male [60.35%] and 205 female [39.65%]] patients were divided into 7 groups according to decades from age 12 to 80 years. Patients older than 40 years predominated [318 [61.5%]]. Metabolic coma was predominant cause in almost all age groups. Structural coma was increasing progressively with the age. Poisonings were the common cause in patients under 30, representing 35.85% of all comas in the age group 12-20, and 33.70% in the group from 21-30 years. In the next two decades [31-50 years], hepatic and renal failure predominated making up more than half of all causes. Leading causes among males we re poisonings [69 cases], hemorrhagic CVA [48 cases], ischemic CVA [24 cases], renal failure [28 cases] and hepatic coma [35 cases]. Similarly among females causal distribution revealed renal failure [34 cases], followed by hepatic coma [29 cases], and hemorrhagic CVA [26 cases]. Out of the 476 [92%] patients whose outcome could be determined 297 [57.4%] were discharged after recovery and 179 [34.6%] died. Eighty out of 205 female patients died [39%], while 99 out of 312 males had a fatal outcome [31.7%]. We conclude that coma etiology has a significant effect on prognosis, while such significance could not be assigned to age or sex

Pulmonary aspergillosis in a child with hepatic failure.

Invasive aspergillosis is described more frequently as a complication of neoplastic disease and in immunocompromised patients. Hepatic failure is not a generally recognized risk for pulmonary aspergillosis. We report a 3-year-old boy who presented with hepatic failure and pneumonia and whose autopsy revealed liver cirrhosis and pulmonary aspergillosis.

Pathogenesis of hepatic encephalopathy: update on molecular mechanisms.

Hepatic encephalopathy (HE) is a major neuropsychiatric complication of acute and chronic liver failure. Neuropathologically, HE in chronic liver failure is characterized by astrocytic (rather than neuronal) changes known as Alzheimer type II astrocytosis and in altered expression of key astrocytic proteins. Magnetic resonance imaging in cirrhotic patients reveals bilateral signal hyperintensities in globus pallidus on T1-weighted imaging, which appear to result from manganese deposition. Proton (1H) magnetic resonance spectroscopy shows an increase in glutamine resonance in brain, a finding that confirms previous biochemical studies and is consistent with increased uptake of ammonia by the brain (glutamine synthesis). Recent molecular biological studies show an increased expression of several genes coding for neurotransmitter-related proteins in chronic liver failure. Such genes include those for monoamine oxidase (MAO-A isoform), nitric oxide synthase (nNOS isoform) and the peripheral-type benzodiazepine receptor. Activation of these systems may lead to alterations of monoamine and amino acid neurotransmitter function and changes in cerebral blood flow in chronic liver failure.

Prevalence of hepatitis B and hepatitis C virus coinfection in chronic liver disease.

Coinfection with HBV and HCV may lead to serious consequences. The present study was done to find out the prevalence of coinfection in patients with chronic liver disease. From patients with hepatitis and chronic liver disease 1673 samples were received and analysed for HBsAg by ELISA. 1342 samples were analysed for anti HCV by third generation ELISA. 493 samples positive for HBsAg were also analysed for Anti HCV to see the prevalence of coinfection. 15(3.0%) were found positive for both HBsAg and anti HCV. Out of 15 patients with coinfection 4 (26.6%) had HCC. Prevalence of HCC in patients with coinfection was higher than either infection alone i.e. HBV-9.1% and HCV-16.5%.

Effect of renal dysfunction in fulminant hepatic failure.

BACKGROUND: Effect of renal dysfunction in fulminant hepatic failure is not studied extensively. METHODS: Fifty consecutive patients of fulminant hepatic failure were studied prospectively to determine the prevalence of renal failure and its effect on survival. RESULTS: The mean age of these patients was 36 +/- 7.2 years and there were 21 males and 29 females. Twenty two patients (44%) were hepatitis B surface antigen (HBsAg) positive. Renal dysfunction was observed in 19 patients (38%). Acute tubular necrosis was seen in 7 patients (38%) while prerenal azotemia and functional renal failure occurred in six patients each (37%). Renal failure occurred more commonly in patients with jaundice. In these patients it occurred in less than four days and prior to onset of encephalopathy, ascites, and gastrointestinal hemorrhage. Histopathological examination of kidney (done in 8 patients) revealed acute tubular necrosis in 4 patients while patients with functional renal failure and prerenal azotemia had normal histology. A good correlation was observed between biochemical parameters and histology of kidney in all the patients. The survival amongst the patients with FHF was 28% (14 of 50 patients). Poor prognostic indicators were a leukocyte count of more than 16.5 x 10(9)/liter, prothrombin index of less than 34%, a peak serum bilirubin of more than 376 mumol/liter and presence of renal failure. Only 3 of 19 patients with renal failure survived. CONCLUSIONS: Renal dysfunction is a major indicator of poor prognosis in patients with FHF.

Hepatitis autouinmune en niños. Presentación inicial como falla hepática fulminante / Autoimmune hepatitis in children. Initial presentation of fulminant hepatic failure

There are few cases reported of autoinmune hepatitis (AIH) tipe 2 presenting as fulminant hepatic failure (FHF) in children. The purpose of this study was to report three girls with AIH type 2 that presented as FHF. METHODS: Over a period of 12 years, 123 patients with AIH diagnosed based on international criteria, 9 (7 per cent were type 2.3 of them presented as FHF. Other etiologies (viral, metabolic and toxic) were ruled out. The treatment was started with prednisone (2 mg-kg-day) and azathioprine (2 mg-kg-day). EVOLUTION: Patients 1 and 3 died while waiting for liver transplant (LT) at 72 and 48 hours after initiating medical treatment. Patient 2 underwent LT3 days after starting treatment, with excellent evolution at 3 years and 7 months of follow up. CONCLUSIONS: 1--AIH type 2 was very infrequent in our group. 2--33 per cent of cases had initial presentation as FHF. 3--The course of the disease was aggressive, not responding to immunosupreessive therapy. The evolution was unfavorable in all patients. 4--LT is an alternative treatment for this severe disease.

Clinicopathological profile of subacute hepatic failure.

Twenty two patients of subacute hepatic failure (SAHF), diagnosed when jaundice progressed for more than 8 weeks with appearance of ascites, with or without encephalopathy, along with biochemical evidence of hepatocellular damage, were studied. The male and female ratio was 4.5:1 and majority (45.4%) of cases were between the age group of 41-50. The mean biochemical values were: S.bilirubin; 9.2 +/- 3.8 mg/dl SGOT; 94.4 +/- 25.0 I.U./lit., SGPT; 107.8 +/- 32.7 I.U./lit., S.Protein; 5.2 +/- 3.5 secs. Ascitic fluid analysis showed transudate in 16 (72.7%) and exudate in 6 (27.2%) patients. Bacterial peritonitis was found in 5 (22.7%) patients. Liver biopsy showed bridging and submassive necrosis. The complications developed in the hospital were: renal failure (36.3%), infection (27.2%), G.I. bleeding (18.1%) and encephalopathy (13.6%). The mortality was (86.3%). Out of 3 (13.6%) patients who survived, only two recovered completely and one had biochemical evidence of hepatocellular necrosis after 6 months of follow up.
