ABSTRACT

The goal of this study was to determine the prevalence, epidemiology and clinical-therapeutical evolution of hepatolithiasis (HL) in Argentina. With this purpose a survey was conducted sending a questionnaire to ten referencial and interventional radiology centers in the country. Seven centers answered on time. In the last five years a total of 8,736 consecutive patients were examined for cholangiography (endoscopic retrograde cholangiography, PTC). A total of 5,920 (68%) were biliary lithiasis and 53 (0.9%, range 0.5-2.6%) of these were HL. In case of HL the diagnostic procedure was the ERCP in 68% of the cases, and the PTC in the remainder 32%. The patients with HL (53% females, mean age 52, range 23-85) clinically presented cholangitis (79%); pancreatitis (6%) and five (9.4%) showed evolution to a biliary cirrhosis. Associated diseases or abnormalities of the biliary tree were: biliary postsurgical strictures (BPS), 28%; Caroli's Syndrome, 20%; and choledocholithiasis, 28%. While a 9.4% presented a "biliary history" (that was defined as two or more episodes of biliary surgery) and a 5.7% lacked associated or predisposing diseases. Follow-up was lost in 23% of the cases and in 77% a follow up of 38 months (range 8-60) was observed with 4.8% mortality rate. The treatment was hepatobiliary surgery in 58% of the cases; endoscopic papillotomy in 17% and combined treatments that included extracorporeal shock wave lithotripsy and ursodeoxycholic acid (UDCA) in 15%. Four out of 53 cases (7.5%) received UDCA as the only successful therapy. HL is an entity with high biliary morbidity in 85% of the cases and development in to cirrhosis in 9.4%. When the diagnosis is made in the western world both BPS and Caroli must be discarded first. Combined treatments or only UDCA are new therapeutical alternative in the western world.

ABSTRACT

A fin de determinar la prevalencia epidemiología y comportamiento clínico-terapêutico de la hepatolitiasis (HL) en el país se envió un cuestionario a 10 centros de referencia, en Radiología invasiva de vía biliar. De 10 centros encuestados, 7 (70 por ciento) contestaron en tiempo y forma. Reuniéndose un total de 8.736 colangiografías (C) en los últimos 5 años: 5.920 (68 por ciento) fueron litiasis biliares y 53 de estas resultaron HL (0.9 por ciento, rango 0,5-2.6 por ciento). El método diagnóstico fue la C. retrógrada en el 36 (68 por ciento) y en el 17 (32 por ciento) la C. transhepática. De 53 pacientes con HL (53 por ciento, x de edad 52, rango 23-85); el 79 por ciento (42/53) se presentó clínicamente con una colangitis; un 6 por ciento 3/53) padeció una pancreatitis aguda y un 9.4 por ciento (5/53), evolucionó a una cirrosis biliar. Las enfermedades predisponentes a HL fueron: en el 28 por ciento (15/53) estenosis postquirúrgica de la via biliar (EPQ); en el 20 por ciento (11/53) Enfermedad de Carolí en otro 28 por ciento (15/53) panlitiasiscoledociana. Mientras que un 9,4 por ciento (5/53) presentó una "historia biliar" (dos o más intervenciones sobre la via biliar) y en un 5,7 por ciento (3/53) no se hallaron factores predisponentes. En un 77 por ciento se observó un follow-up de 38 meses (rango 8-60), con una mortalidad de 4,8 por ciento (2/41): siendo tratados con cirurgía en el 58 por ciento de los casos (31/53); papilotomía en el 17 por ciento (9/53) y tratamiento combinados en el 15 por ciento (8/53) que incluían a litotripsia extracorpórea y Ac. Ursodesoxicólico(AUDC). Cuatro de 53 (7.5 por ciento) recibieron AUDC como única terapéutica. Se concluye que la HL es una entidad con alta morbilidad biliar (85 por ciento) y heoática (cirrosis en el 9.4 por ciento). Cuando se diagnostica en Occidente, debe buscarse EPQ o un Carolí. Siendo los tratamientos combinados o el AUDC como única alternativa, una nueva modalidad terapéutica del mundo occidental.

ABSTRACT

BACKGROUND: Although non-A, non-B (NANB) viral hepatitis has been implicated as an etiology of fulminant hepatitis, hepatitis C virus (HCV) has not been shown to result in acute hepatic failure and hepatitis E virus (HEV) has predominantly been associated with fulminant hepatitis among pregnant women. METHODS: Using polymerase chain reaction to detect HCV and HEV genomes, four-antigen radioimmunoblot assay (4-RIBA) to measure anti-HCV antibodies, and enzyme-linked immunosorbent assay (ELISA) to detect anti-HEV immunoglobulin M (IgM) antibodies, 17 patients with sporadic fulminant or subfulminant hepatitis of presumed NANB viral etiology were studied. RESULTS: The diagnosis of acute NANB viral hepatitis was made based on clinical information, serological tests, biochemical profiles, and pathological features. All 17 patients were negative for anti-HEV IgM antibodies and HEV RNA in either serum and/or liver. HCV RNAs were detected in 2 patients although anti-HCV antibodies were negative in all of them. CONCLUSIONS: It is shown that HCV is infrequently associated with and HEV is not an identifiable cause of presumed NANB fulminant or subfulminant hepatitis in this patient population. Although further studies will be required for identification of the causative agent, it is possible that another agent is responsible for the occurrence of sporadic NANB fulminant or subfulminant hepatitis.

ABSTRACT

Con el objeto de evaluar la prevalencia de los anticuerpos contra el virus de la hepatitis C (antiHCV IgG) en diferentes hepatopatías crónicas hemos estudiado un grupo de 148 pacientes divididos en: Grupo I compuesto por 35 pacientes con hepatitis crónica con o sin cirrosis, con antecedentes definidos de contagio parenteral, Grupo II de 39 pacientes con hepatitis crónica con o sin cirrosis sin antecedentes de transmisión parenteral, Grupo III de 37 pacientes con el diagnóstico de hepatitis crónica autoinmune, Grupo IV compuesto de 31 pacientes con cirrosis biliar primaria y Grupo V de 6 pacientes con síndrome colestático intermedio entre CBP y HCA. En todos se descartó la etiología medicamentosa, por el virus B, acoholismo, afecciones metabólicas o colangiotis esclerosante primaria. Las determinaciones en por lo mesmo dos instancias en cada uno de antiHCV IgG se efectuaron con equipos de laboratorio Ortho-Chiron (ELISA). Se consideraron como positivos sólo aquellos con relación de positividad superior a 2.0. Los resultados se expresan en la siguiente tabla: Grupo I: 35 pacientes, anti HCV IgG 32, 94.2%; Grupo II: 39 pacientes, anti HCV IgG 15, 38.4%; Grupo III: 37 pacientes, antiHCV IgG 8, 21.6%; Grupo IV: 31 pacientes, anti HCV IgG 1, 3.22%; Grupo V: 6 pacientes, antiHCV IgG 2, 33.3%. En 2 de los pacientes con anti HCV del grupo 3 y en uno del Grupo 4 hubo antecedentes transfusionales que podrían justificar dicha positividad independientemente de la enfermedad de base. Conclusiones: Se considera útil la detección de los anticuerpos anti-HCV IgG para caracterizar a las hepatitis NANB con antecedentes transfusionales o parenterales. Parece ser frecuente la etiología por el virus C también en pacientes con hepatitis crónica sin antecedentes parenterales. El virus C parece hallarse excepcionalmente en la CBP, en cambio algunos casos con síndrome intermedio podrían obedecer a esta etiología. Cabe plantear la duda si en algunos de los pacientes con suspecha HCA se trata de HC por virus C con componente inmunológico o si la metodología serológica aún presenta un margen de error que deberá ser subsanado en el futuro (AU)

ABSTRACT

UNLABELLED: In order to evaluate the prevalence of antibodies IgG against the virus of hepatitis C (anti HCV) in different forms of chronic liver disease negative for virus B markers of alcoholism, we studied 148 patients (pts) divided into several groups. Group I: Composed of 35 pts. with chronic active hepatitis (CAH) with definite evidence of parenteral exposure to blood. Group II: included 39 pts. with CAH without immune markers or evidence of possible parenteral transmission. Group III: Included 37 pts. with the diagnosis of CAH of autoimmune type with positivity of antinuclear, anti smooth muscle or both antibodies with range of positivity of 1:80 or higher. Group IV: was composed of 31 pts. with the diagnosis of primary biliary cirrhosis (PBC). Finally group V included 6 pts. with an overlap syndrome between CAH and PBC. The prevalence of anti HCV in the different groups was as follows: [table: see text] Two of the pts. positive for anti HCV in group III and 1 in group IV revealed parenteral exposure to blood or blood product. CONCLUSIONS: The determinations of anti HCV in order to characterize the posttransfusional NANB chronic hepatitis is of value. Positivity of anti HCV is high in cryptogenic chronic hepatitis and rare in PBC. In CAH of autoimmune type and in the overlap syndrome the prevalence was higher than expected. The question if we are dealing with false positivity or an uncertain diagnosis of autoimmunity is raised.
