RESUMEN

UNLABELLED: Drug addicts frequently have liver diseases for different reasons: alcohol abuse, the drugs themselves, but more often hepatitis B and C infections. AIDS is common in this population as well and could also affect the liver directly or in the form of hepatocellular or biliary damage. We conducted this study to determine the prevalence of liver diseases, alcoholism, hepatitis B and C infections, and HIV positivity in this population. We studied a cohort of 137 persons, all with a history of drug abuse, and investigated the quantity of alcohol intake, the kind of drug used, and he routes of drug administration. RESULTS: We found liver disease in 33.6%. The prevalence of alcoholism was 65.4%, of HCV 67.3%, and of HBV 17.3%. HDV was undetectable, whereas we found HIV at a frequency of 17.3%. HCV RNA was detected in 85.4% of HCV. The drug most often used was cocaine at 90.4%, followed by marihuana at 88.3%; LSD use occurred in 17.5%. We found parenteral drug use in 43.1%. We performed 22 liver biopsies, 21 associated with HCV, and detected histological changes consistent with chronic hepatitis in 17, with cirrhosis in 4, and with hepatocellularcarcinoma in 1.

RESUMEN

Fifty heterosexual partners out of 50 patients (index cases) without confirmed or probable risk factors of parenteral transmission by HCV were studied from 1/1997 to 1/2001. The index cases were HCV Ab (+) (EIA 3rd Abbott and PCR + by RT-nested PCR). The couples with probable or confirmed risk factors of parenteral transmission were strictly excluded. No case of HCV infection was found, suggesting that sexual via wouldnt be a direct transmission of HCV (AU)

RESUMEN

UNLABELLED: It is accepted that the practice of odontology implies a risk of BBV and HCV transmission but the study of does not. This work tries to determine the prevalence of HBv Ac and HCV Ac (by ELISA) in odontology students and whether there is any relation to the year of study and/or the presence of other risk factors. 188 students in their last three years of studies were investigated, all the participants filled out a clinical epidemiological form. 89 women (47.3%) and 99 men (52.7%), x age was 24.8. 50 (26.7%) had other risk factors. 160 (85.1%) fulfilled biosecurity norms and 40 (21.2%) had a labour accident. RESULTS: None of the analyzed sera were positive for HCV Ac (0%) and 1 was positive for HbcAc. CONCLUSION: The prevalence of HBv Ac and HCV Ac is extremely low with no relation to the year of study or any other risk factors.

RESUMEN

We present a case of Idiopathic Portal Hypertension (IPH) with Splenic infarct in a 23-year-old female. She was referred to the hospital because of enlargement of liver and spleen. A computed axial tomography revealed Splenic infarct. The spleen was surgically removed. At laparotomy the liver was found to be enlarged and a liver biopsy performed. The biopsy showed characteristic changes of IPH. After the splenic resection all hematologic manifestations disappeared, suggesting that they were due to hypersplenism. The IPH is very uncommon in western countries. We don't know of any case previously reported in Argentina and our patient is the first case of IPH with Splenic infarct.

RESUMEN

La Hipertensión Portal Idiopática (HPI) es un síndrome clínico-patológico caracterizado por hipertensión portal no cirrótica. Su prevalencia es baja en occidente y no hemos encontrado casos comunicados en nuestro país. La patente histológica característica de HPI es fibrosis y obliteración de las venas porta intrajepáticas (flebosclerosis), fibrosis portal y periportal, y formación de vasos aberrantes. Presentamos un caso que nos fue derivado por hepatoesplenomegalia y pancitopenia. Al tercer día de internación presentó dolor abdominal y mediante una TAC abdominal se le diagnosticó un infarto esplénico . Posteriormente se le realizó una esplenectomía y biopsia hepática. Los parámetros hematológicos mejoraron después de la operación. Los estudios de imágenes y endoscópicos confirmaron la presencia de hipertensión portal: circulación colateral, vena porta permeable y dilatada y várices esofágicas. Los cambios histológicos del hígado concordaron con el diagnóstico de HPI. Los signos y síntomas característicos de HPI son hemorragias digestivas relacionadas con la hipertensión portal y pancitopenia secundaria al hiperesplenismo y su principal causa de muerte es la hemorragia por várices esofágicas. Como complicación infrecuente de la HPI se ha descripto la trombosis de la vena Porta. En cambio el infarto esplénico, es una rara complicación de la hipertensión portal por cirrosis y del transplante hepático, pero no se han publicado casos en pacientes con HPI. (AU)

RESUMEN

In order to ascertain the clinical and epidemiological features of acute liver failure (ALF), we analyzed the clinical histories of 22 patients from La Plata city, with the diagnosis of ALF (prothrombin level or factor V below 50%) seen between November 1996 and November 2000. Age, sex, hepatic encephalopathy, reason for consultation, etiology, hepatic biochemical tests, serum creatinine, glycemia, digestive hemorrhage, course and treatment variables were analyzed. What is remarkable is the high frequency of the toxic etiology and of infection by HDV, as well as the high prevalence of ascites and the low incidence of hepatic encephalopathy. We think that the high survival rate we found is due to the early diagnosis and early referral of the patients to the intensive care unit and to centers with programs for liver transplantation.

RESUMEN

Se analizaron las historias clínicas de 22 pacientes con IHA (Protrombina y/o factor V menor de 50 por ciento). La ictericia fue el motivo de consulta más frecuente (54.5 por ciento). Doce pacientes (54.5 por ciento) presentaron EH, sólo dos de los cuales la teníam en el momento del ingreso. Doce (54.5 por ciento) presentaron ascitis en algún momento de la evolución. Etiología desconocida en 6 (27.2 por ciento), fármacos 6 (27.2 por ciento), HBV 5 (22.7 por ciento) 2 de los cuales teníam además HDV y 3 (13.6 por ciento) autoimmune. Se halló una alta tasa de sobrevida. (Au)
