ABSTRACT

INTRODUCTION: Insulin resistance plays a major role in the pathogenesis of nonalcoholic steatohepatitis (NASH). Insulin-sensitizing drugs like metformin may have a role in the treatment of this disease. OBJECTIVE: To determine insulin resistance and the role of metformin in the treatment of NASH. METHODS: We prospectively studied 25 patients with NASH over a period of one and a half years. In addition to clinicopathological profile, we studied the insulin resistance by insulin tolerance test in 10 of them; seven of them, who did not respond to 3 months of low-calorie, low-fat diet, exercise, weight reduction and ursodeoxycholic acid (UDCA), were treated with metformin for six months. Results were compared with control groups. RESULTS: All 10 patients with NASH tested had low insulin sensitivity; there was significant difference in the rate constant for insulin sensitivity (Kitt) between patients with NASH and normal volunteers. Thirteen (52%) patients responded to dietary restriction, exercise, weight reduction and UDCA. Four of 7 patients treated with metformin had normalization of ALT. CONCLUSION: Patients with NASH have insulin resistance. Metformin may have a role in the treatment of these patients.

ABSTRACT

Plasma vitamin A carotene levels were estimated in 46 normal healthy adults, 34 patients with acute viral hepatitis and 12 patients with cirrhosis. Low vitamin A levels were observed in 16 [48 percent] cases of hepatitis and 9 [75 percent] cases of cirrhosis. Significant [P = 0.05] lowering of plasma vitamin A was observed in both the conditions. Carotene levels were normal in all the cases

ABSTRACT

The aim of this study was to evaluate the clinical significance of serum hyaluronan (HA) as a marker of liver fibrosis in patients with chronic liver disease. Serum HA was measured by an ELISA-based method in 28 patients with chronic hepatitis (CH), 43 patients with liver cirrhosis (LC), 57 patients with hepatocellular carcinoma (HCC) and 60 healthy controls. Mean serum HA concentration in patients with LC was 1,376.80 +/- 2,568.85 ng/ml which was significantly higher than those in patients with CH, HCC and the controls (575.93 +/- 732.58, and 426.36 +/- 687.33, and 117.86 +/- 311.11 ng/ml, respectively). Based on a ROC curve analysis, a cut-off point of 354 ng/ml discriminated between LC and other groups with a sensitivity, specificity and accuracy of 82.4%, 78.2%, and 80.2%, respectively. Mean HA concentrations were correlated with the degree of liver fibrosis, but not the grade of necroinflammatory activity. In patients with LC, the mean serum HA level was significantly increased in the Child C group (3,977.96 +/- 4,906.21 ng/ml) in comparison with the Child B and A groups (1,002.63 +/- 448.55, and 537.90 +/- 424.16 ng/ml, respectively). We conclude that serum HA concentrations reflect the extent of liver fibrosis and severity of cirrhosis. Thus, serum HA can be a diagnostic marker of liver fibrosis and cirrhosis in patients with chronic liver disease.

ABSTRACT

Objetivo: Revisar la experiencia del estado previo y actual de la hepatitis post-transfusional (HPT), así como los eventos principales que han impactado en la prevalencia de la enfermedad y las alternativas actuales que podrían erradicar efectivamente la HPT. Discusión: En el desarrollo de HPT participan factores del donador y del receptor, el número de unidades y el tipo de productos sanguíneos transfundidos. Durante la década de los sesenta, el desarrollo de la enfermedad se informaba hasta en 65 por ciento de los receptores, mientras que en la actualidad parece ser alrededor del 2 por ciento. Los hechos que en forma más aparentes se han relacionado con el descenso en la prevalencia de la HPT son: el reconocimiento de la frecuencia verdadera de la enfermedad; la exclusión de donadores comerciales; el descubrimiento del virus de la hepatitis B; el reconocimiento de otros agentes causales y el desarrollo de pruebas específicas e inespecíficas para su identificación; el reconocimiento de la transmisión del SIDA y la exclusión de donadores con conductas de riesgo. Al mismo tiempo se han desarrollado estrategias preventivas como la inactivación viral o la inmunoprofilaxis, así como diversos programas para evitar el uso de sangre homóloga, tales como transfusión autóloga, fármacos y substitutos de sangre

ABSTRACT

Fifty patients with primary hepatocellular carcinoma [Hcc], 50 patients with secondary hepatoma and 30 apparently healthy blood donors were assayed for hepatitis B virus [HBV] markers by the enzyme linked immunosorbant assay [ELISA].All patients and controls were chosen from the National Cancer Institute, Cairo University [NCI].The results showed that the hepatitis B surface antigen [HBsAg]was positive in 72 percent [36 out of 50 Hcc patients],Anti-HBc was positive in 74 percent [37 out of 50 Hcc patients],and HBeAg was positive in 34 percent [17/50] Hcc patients. While in the other secondary hepatoma patients group, HBsAg was positive in 18 percent[9/5O], anti-HBc in 16 percent [8/50] and HBeAg in 10 percent [2/20] of the patients. The control group showed 10 percent [3/30] positive HBsAg, anti-HBc and HBeAg, These results showed the close association between HBV infection and Hcc .Alpha-fetoprotein level was also estimated in both groups before and after treatment. It showed decrease in the level after treatment

ABSTRACT

We measured plasma levels of fibrinogen degradation products (FgDP) with newly developed enzyme-linked immunosorbent assay based on monoclonal antibody to assess the fibrinogenolytic state in 52 patients with various liver diseases (27 patients with liver cirrhosis, 10 with chronic hepatitis, 7 with acute hepatitis, 6 with hepatocellular carcinoma, 2 with intrahepatic cholestasis). As compared with 20 healthy subjects (upper limit: 580 ng/ml), elevated plasma levels (660-32000 ng/ml) of FgDP were found in 19 (36.5%) patients. When analyzed according to the underlying disease categories, the magnitude of elevations of FgDP were most prominent in patients with chronic hepatitis. No correlation was found between plasma FgDP levels and serum AST or ALT activity. These findings indicate that increased primary fibrinogenolysis is not rare in liver disease, but poorly correlates with liver function.

ABSTRACT

Hepatitis is a known manifestation of congenital syphilis, however hepatitis developing during penicillin therapy is unknown. Ten patients of congenital syphilis were studied and serial liver enzymes were done before and after starting penicillin therapy. Eight of the ten patients developed hepatitis after initiating penicillin therapy. Whether hepatitis in these cases was secondary to toxic reaction to the products of treponemal lysis or an autoimmune reaction needs to be investigated.

ABSTRACT

For all patients and controls serum total cholesterol [TC], serum triglycerides [TG], serum high density lipoprotein cholesterol [HDL-c] were estimated colorimetrically and also serum apolipoproteins [apo A, A1 and B] were assayed by immunodiffusion. BHF and PHC patients showed significant decreases in the mean values of serum TC, TG, HDL-c an apo A, A1 and B compared to controls. Also PHC patients showed significant decreases in serum levels of the same parameters compared to BHF patients. Although the serum levels of HDL-c and apo A1 were significantly decreased in both groups of patients, yet the mean value of apo A1/apo B ratio was higher in both groups compared to controls and the rise was statistically significant in BHF patients and insignificant in PHC patients. Also there was a significant reduction of the serum levels of HDL-c and apo A1 in PHC compared to BHF patients and comparison of the mean value of apo A1/apo B ratio in the two groups was found to be statistically insignificant

ABSTRACT

En la práctica médica es frecuente encontrar patología extrahepática a la que se asocian manifestaciones de hepatitis que ha recibido diferentes denominaciones, siendo las más usual hepatitis reactiva o reaccional inespecífica, que no obstante no es aceptada por todos. Como ejemplo se presentan 20 casos atendidos en el Hospital Cayetano Heredia, señalándose los hallazgos clínicos, de laboratorio y anátomo-patólogicos. Se establece que el cuadro clínico predomina la enfermedad de fondo, presentándose en algún momento fiebre, coluria, ictericia y hepatomegalia ligeramente dolorosa. Se encuentra hiperbilirrubinemia que no excede de 3 a 4 mg/dl a predominio de la conjugada; elevación de las transaminasas que no suelen pasar de 250-300 UI/dl y fosfatasa alcalina elevada en 2 a 3 veces lo normal. La biopsia hepática realizada en todos los casos está caracterizada por cambios inflamatorios inespecíficos: injuria o necrosis focal leve, infiltración celular de tipo portal y en algunos dilatación sinusoidal o cambios mínimos a nivel de los colangiolos. Se plantea que las alteraciones se producen por la susceptibilidad hepática a un conjunto de posibles factores tóxicos, metabólicas, circulatorios, inmunológicos y otros aún no conocidos.El pronóstico y tratamiento se relacionan con la enfermedad de fondo, evitando los hepatotóxicos

ABSTRACT

Vinte e quatro casos de hepatite fulminante (HF), internados na Clínica de Doenças Infecciosas e Parasitárias do Hospital das Clínicas da Faculdade de Medicina da Universidade de Säo Paulo durante o período de janeiro de 1976 a dezembro de 1986, foram revistos para a obtençäo de dados clínicos, epidemiológicos e laboratoriais. 88% dos pacientes morreram. Vinte (83%) dos pacientes apresentaram hemorragias, dentre os quais 19 morreram (95%). Infecçöes bacterianas secundárias ocorreram em 14 pacientes (58%) todos os quais faleceram. Ascite foi notada em 3 casos e edema cerebral em 16 casos. Os valores máximos de ALT obtidos para cada paciente durante a internaçäo variaram de 81 a 40460 UI/l. Treze pacientes tiveram elevaçäo de creatinina (54%). A atividade do tempo de protrombina variou de 2,1% a 67%. A febre esteve presente em 20 casos (83%). A encefalopatia surgiu durante as 2 primeiras semanas de doenças em 72% dos casos. Em 7 casos havia doenças associadas à hepatite. A etiologia näo pode ser determinada em 13 casos; 3 casos foram por febre amarela; e 6 casos por outros vírus. Em 1 caso a causa foi drogas e em um caso, possivelmente, foi álcool. Os autores acreditam que a definiçäo de HF merece discussäo antes de ser totalmente aceita. Neste estudo, a HF foi uma doença que acometeu principalmente jovens. A letadade encontrada foi semelhante a de outros estudos. Fatores que contribuiram para o óbito foram hemorragias e infecçöes bacterianas secundárias. Fatores de piora do prognóstico de hepatite foram a presença de outras doenças associadas e de procedimento cirurgico. Os níveis de ALT durante a internaçäo näo refletiram a gravidade da hepatite. Os autores acreditam que a febre amarela deve ser considerada um agente etiológico de HF quando o seu quadro clínico seja compatível com tal, embora os mecanismos fisiopatológicos da encefalopatia sejam ainda obscuros. Os dados clínicos dos 3 casos de febre amarela säo apresentados à parte

ABSTRACT

El diagnostico diferencia de la hepatitis viral se inicia con la busqueda de orina oscura y bilis en la orina. Estos signos de hiperbilirrubinemia conjugada descartan la existencia de una enfermedad prehepatica. En la actualidad se llevan a cabo enstudios de los niveles elevados de transaminasas, caracteristicos de hepatitis infecciosa, y una historia cuidadosa para descartar la hepatitis inducida por toxicos o medicamentos que puede simular una hepatitis viral aguda. Un buen indicio de colestasis es la elevacion de la fosfatasa alcalina. Este diagnostico puede ampliarse mediante la ultrasonografia. Los sintomas clasicos de la hepatitis viral son ictericia, nauseas, vomitos, malestar, anorexia y dolor sordo en el cuadrante abdominal superior derecho. Sin embargo, se requiere de estudios serologicos para detectar la presencia de agentes virales especificos.

ABSTRACT

The serum levels of IgA, IgG and IgM were determined by single radial immuno-diffusion technique in 104 male patients of acute viral hepatitis. HBsAg was detected by counterimmuno-electrophoresis (CIEP) and 51% were HBsAg + ve. IgA, IgG and IgM levels were found to be higher than normal levels. Mean IgA and IgG levels were same in HBsAg + ve and HBsAg--ve patients. Mean IgM levels were however, higher in HBsAg--ve patients.

ABSTRACT

Con el objeto de evaluar la utilidad de la ferritina en suero (Ft) como indicador de reservas de hierro de pacientes alcohólicos y no alcohólicos con hepatopatías clínicas se estudiaron 35 pacientes: 18 con cirrosis o fibrosis alcohólica y 17 con padecimientos hepáticos de etiología diversa, no alcohólicos. Los pacientes alcohólicos tenían 3 a 32 meses de abstinencia alcohólica. Las reservas de hierro se establecieron mediante la cuantificación de hierro no hemínico (HNH) en biopsia hepática. En 8 casos del grupo de alcohólicos (44%) y en 4 de los no alcohólicos (23%) el HNH estuvo por arriba de muestras cifras de referencia (> 48 mg/100 g en varones y > 20 mg/100 g en mujeres). En los pacientes alcohólicos se obtuvieron correlaciones directas significativas entre Ft y ALAT y Ft vs, bilirrubina total, mientras que estas correlaciones inversas y no significativas en los no alcohólicos. La correlación entre HNH y Ft fue estadísticamente significativa en los no alcohólicos (r = 0.667), pero fu más baja en los alcohólicos (r = 0.478). Concluimos que: a) la siderosis hepática, descrita en una proporción considerable de los bebedores activos, permanece en los alcohólicos que tienen 3 o más meses de abstinencia alcohólica, b) en individuos con hepatopatías crónicas no alcohólicos la Ft aparentemente sí refleja reservas de hierro, c) en los alcohólicos la inflamación o necrosis hepática modifica los niveles de Ft, por lo tanto este parámetro no es útil para establecer las reservas de hierro en estos pacientes

ABSTRACT

Con el propósito de valorar las modificaciones que ocurren en las liproteínas plasmáticas en el alcoholismo crónico y su relación con las alteraciones observadas en la histología hepática fueron estudiadas un grupo de 62 alcoholistas crónicos y uno de 36 sujetos normales de similar sexo y edad que fueron empleados como controles. En base a los hallazgos en la punción biopsia hepática los etilistas fueron clasificados como sin lesión a la histología óptica (6 pacientes) hepatitis e hígado graso (18 pacientes) y cirrosis hepáticca (38 pacientes). El grupo de alcoholistas en conjunto mostró aumentos significativos con respecto al grupo control en la gamaglutamiltranspeptidasa, triglicéridos y apoproteína B y una disminución significativa en los valores de C-HDL y de apoproteínas AI. Los etilistas presentaron un descenso gradual y significativo tanto del C-HDL como de la Apo AI a medida que el daño histológico hepático evolucionaba desde "sin lesión histológica" a "cirrosis hepática". Se concluye que los resultados hallados podrían ser debidos a ambos, el efecto metabólico directo del alcohol y el daño estructural hepático irreversible provocado por el mismo
