[Good's syndrome and chronic diarrhea].

Good's syndrome is an infrequent disorder associated with humoral immunodeficiency and thymoma. Patients usually present severe or chronic infections. The most frequent are sinopulmonary infections sometimes associated with bronchiectasias. Another complication is chronic diarrhea, frequently associated with malabsorption, which can be due to a mucosal lesion, infection with gastrointestinal pathogens, or bacterial overgrowth. We describe a patient with Good's syndrome and chronic diarrhea due to bacterial overgrowth.

[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.

Influence of the transmission route and disease duration in the histopathology of chronic hepatitis C: a study of 101 patients.

OBJECTIVE: Different studies have demonstrated that factors such as transmission route, disease duration and age at the time of infection can influence the histological evolution of chronic hepatitis by the hepatitis C virus (HCV). The aim of this study was to determine if epidemiological factors such as disease duration and transmission route influence the severity of the histological lesions of patients with chronic hepatitis by HCV. DESIGN: A prospective study. METHODS: The hepatic biopsies of 101 patients diagnosed with chronic hepatitis by HCV were studied. The patients were divided into three groups according to transmission mode: (1) post-transfusional (n = 28), (2) associated with the use of drugs by parenteral route or intravenous drug use (n = 28), and (3) sporadic hepatitis (n = 45). RESULTS: We found more severe forms of hepatopathy in post-transfusional hepatitis and sporadic groups than in the intravenous drug user group of patients. The disease evolution time was significantly higher in patients diagnosed as having chronic active hepatitis with or without cirrhosis (13.8 +/- 9 years) than in patients with chronic persistent hepatitis (8 +/- 4 years), P < 0.01. We found a significant correlation between the evolution time of the infection by HCV and the Histology Activity Index (P < 0.01). The multivariate analysis showed that only the transmission route and the disease evolution time are predictive variables of Histology Activity Index in chronic hepatitis C. CONCLUSION: These results suggest that the post-transfusional and sporadic transmission routes and a greater evolution time of the disease are epidemiological variables that are associated with the presence of more severe histological lesions in chronic hepatitis C.

[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.

[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.
