[Acute hepatitis due to ingestion of Teucrium chamaedrys infusions].

Herbal remedies, used for many years for therapeutic purposes, have traditionally been considered safe and effective. Herbal medicine toxicity has been infrequently reported in Spain. We present two cases of acute hepatitis after ingestion of herbal infusions over a period of several months. Among the plants consumed was Teucrium chamaedrys (germander), which has been associated with several cases of hepatotoxicity, mainly in France. After ruling out other causes of hepatitis, we consider that Teucrium chamaedrys provoked the disease. One patient presented acute, cholestatic hepatitis and another presented mixed (hepatocellular and cholestatic) hepatitis. In both patients, the disease was resolved after discontinuing the intake of the herbal teas. We believe that herbal medicine toxicity may be increasing due to the growing consumption of these products. Finally, we emphasize the need to rule out the intake of herbal remedies in patients whose liver tests present abnormalities.

[The histological lesions of chronic hepatitis C as predicting factors of sustained response to the treatment with interferon].

BACKGROUND: Although many studies have been implemented in order to determine the pre-treatment factors that can predict patients' response to interferon (IFN) therapy, it is not yet clear whether characteristic histologic abnormalities in chronic hepatitis C can predict such response. AIMS: The aim of this study were to evaluate, in patients with chronic hepatitis C, (i) the predictive value of histologic lesions for the sustained response to IFN therapy (ii) other pre-treatment (epidemiological and analytical) factors known to be predictive of response. PATIENTS AND METHODS: Sustained response was retrospectively evaluated in two hundred one patients who had been treated with IFN for at least 3 months in four different hospitals from Castilla y León. The following histological parameters were studied as predictors of response: histological diagnosis, Knodell index, grading and stage, characteristic histologic lesions of HCV infection. Epidemiological and analytical parameters were also evaluated. RESULTS: The rate of patient's sustained response to IFN treatment was 16%. None of the histological parameters was useful to predict this response. By univariate analysis, age, disease evolution time, mode of viral transmission, GGT, ferritin and viral genotype were associated with a sustained response. The most powerful, and only independent predictive factor, however, was the genotype (the response odds ratio was 8.6). CONCLUSIONS: Histological parameters do not predict the response to IFN treatment. Other factors (mainly the viral genotype) are associated with a higher response percentage, although no one is useful to decide which patients are going to respond.

[Sinusoidal portal hypertension secondary to nodular regenerative hyperplasia of the liver].

Regenerative hepatic nodular hyperplasia is infrequent and generally appears in association with many other diseases, the most frequent being the Felty syndrome. It may cause portal hypertension and variceal bleeding. A histologic study is necessary for diagnosis since certain biologic data and the nodular appearance of the hepatic surface may be confused with hepatic cirrhosis from which it may basically be, apart from the histologic features, distinguished by its good prognosis due to the absence of liver failure. We present the case of a seropositive patient with regenerative hepatic nodular hyperplasia and rheumatoid arthritis with marked portal hypertension shown in the hemodynamic study performed by our department for presentation of a persistent elevation in transaminases and ultrasonography alterations suggesting hepatic cirrhosis.

[Malignant lymphoproliferative neoplasms and chronic hepatitis C virus infection].

It has been suggested that chronic hepatitis C virus (HCV) infection predisposes to the development of benign and malignant lymphoproliferative disorders. We present 2 cases of malignant lymphoproliferative neoplasias (a non-Hodgkin lymphoma [NHL] and a chronic lymphoid leukemia [CLL]) associated to chronic hepatitis C virus (HCV). The possible etiological role of HCV in the development of these tumors is discussed.

[Idiopathic portal hypertension, multiple focal nodular hepatic hyperplasia, the CREST syndrome and protein S deficiency].

A 54 year old woman with idiopathic portal hypertension, CREST syndrome, protein "S" deficiency and multiple focal nodular hyperplasia is reported. The patient presented several episodes of upper digestive bleeding due to portal hypertension gastropathy and to esophageal varices. Treatment with propanolol and isosorbide 5-mononitrate failed to control recurrent bleeding and a portacaval shunt was performed. At operation, ten hepatic nodes were found, being diagnosed as focal nodular hyperplasia in the pathologic study. Congestive gastropathy, esophageal varices and splenomegaly disappeared after portacaval shunt and bleeding did not recur after a follow-up of twelve months. This results support the role of portal decompressive surgery in the bleeding due to portal hypertension gastropathy.

[Alterations in iron metabolism in chronic anti-HCV positive hepatitis. The relationship with response to interferon treatment].

A prospective study in which the existence of iron metabolism alterations (increase in the serum levels of iron and ferritin and the presence of iron in liver tissue) in a group of 53 patients diagnosed with chronic anti-HCV positive hepatitis was performed. The aim of the study was to determine whether these parameters influence the response to interferon treatment. Elevations were observed in the serum levels of iron and/or ferritin in 17 (32%) of the patients. Higher than normal values of serum iron or ferritin in pretreatment analyses were associated with worse therapeutic response. The basal serum levels of iron and ferritin were significantly higher in non responding patients. No relationship was found between the presence of iron in the hepatic parenchyma and response to interferon treatment.

[Hepatitis C virus infection and porphyria cutanea tarda].

The prevalence of antibodies versus the hepatitis C virus (antiHCV) was studied in a group of 10 patients diagnosed with porphyria cutanea tarda (PCT) and the possible existence of subclinical forms of PCT was determined in 64 patients with chronic anti HCV positive liver diseases. The prevalence of anti HCV was found to be 40% in patients with PCT. In the group of patients with chronic anti HCV positive liver disease only one patient (1.5%) presented an increase in the urinary elimination of porphyrias in the absence of cutaneous lesions of photosensitivity. This study confirms the importance of the hepatitis C virus as a triggering agent of PCT. These results demonstrate the existence of a low prevalence of subclinical forms of PCT among patients with chronic anti HCV positive liver diseases.

[Acute pancreatitis and sarcoidosis: a case report and review of the literature].

We describe a case of sarcoidosis that began as acute pancreatitis. Diagnosis was established by mediastinoscopy. Although involvement of the pancreas is rare and in general asymptomatic, we conclude that sarcoidosis should be included in the long list of factors that can trigger acute pancreatitis.

[Severe gastroesophageal lesions due to caustics: the role of nutritional support].

AIM: Describe the clinical-nutritional state of patients with severe digestive lesions after the ingestion of caustic substances, as well as their nutritional support (NS). PATIENTS AND METHODS: We studied 5 patients diagnosed by means of early endoscopy, treated with artificial nutrition, 4 of whom used enteral nutrition. During the acute phase of the disease, an evaluation of the nutritional state (ENS) was done, by means of the following parameters: body mass index (BMI), creatinine/height index (CHI), visceral proteins, nitrogen content of 24 h urine, and plasma zinc level. The corrected Harris-Benedict equation was used to calculate the energy needs. RESULTS: The BMI did not experience significant changes. The CHI decreased in a large degree. The long life visceral protein did not change notably, and those of intermediate and short life increased. The losses of nitrogen were increased. We found hypozincemia in 4 of the cases. The mean Kcal provided was 2323 +/- 105. CONCLUSIONS: In the described patients, given their catabolic condition, and early ENS and NS should be done. If at all possible, the NS shall be enteral, with or without parenteral support. In our study we have found a cessation of the weight loss, a decrease of somatic protein with a short term re-filling of the visceral protein pol. The zinc levels should be monitored.
