Splenic lymphangioma is very rare, and more so in adults. This condition is often asymptomatic and is incidentally detected by imagenology due to any other differet cause. The final diagnosis should be based on a combination of clinical, radiological, and histopathological findings. Splenectomy is the treatment of choice and the prognosis is good.
The aim of this work was to analyse apoptosis rate, measured by the serum levels of proapoptotic interleukin (IL)-18 and of soluble Fas (sFas), as well as of anti-inflammatory IL-10, in patients with chronic hepatitis C, at baseline and after treatment with interferon alpha and ribavirin. Twenty-seven patients with biopsy-proven chronic hepatitis C were studied, at baseline and after treatment with interferon alpha (21 cases) or pegylated interferon (6 cases) plus ribavirin. A group of 15 healthy sex- and age-matched individuals was selected as control. Serum concentrations of sFas, IL-10 and IL-18 were determined by ELISA in sandwich. The relationship of these molecules to necro-inflammatory and fibrotic activity was evaluated. Evolution of the serum concentrations of these molecules was analysed after treatment. Significantly increased serum concentrations of sFas were detected in patients with chronic hepatitis, compared with controls. Levels of this molecule were significantly correlated with necroinflammatory activity. Likewise, concentrations of IL-10 were significantly increased in the group of patients, compared with controls. Treatment with interferon and ribavirin induced a significant decrease of IL-18 concentration independently of the viral response. In contrast, levels of sFas decreased only in those patients with sustained response to therapy. Finally, baseline levels of IL-10 were significantly increased in patients without response to treatment, compared with those with sustained response, but the concentration did not change with the treatment. Increased serum levels of IL-10 are a negative prognostic marker of response to hepatitis C treatment. A significant decrease of apoptotic rate, as determined by sFas, can be expected in patients with a response to therapy.
Drug-Induced Liver Injury (DILI) is the fourth leading cause of liver damage in Western countries, increasingly becoming a matter of concern for drug prescription. 1 Despite data on antidepressant-induced liver injury being scarce, 0.5%-3% of patients treated with antidepressants may develop hepatitis, 2,3 being the most susceptible population the elderly and those with polypharmacy. 2 Liver damage is in most cases idiosyncratic and unpredictable, and it is generally unrelated to drug dosage. 2 Patients with DILI by antidepressants should be presumed to have increased risk of developing DILI with the same antidepressant or with any other antidepressant that may display cross-toxicity, limiting therapeutic options.
Objective: the hepatocyte growth factor (HGF) is a pleiotropic cytokine produced by hepatic stellate cells and implicated in liver regeneration and fibrosis. Serum levels of HGF vary in liver diseases, reflecting hepatic damage and hepatocellular dysfunction. In this study, serum levels of HGF and the relationship between HGF and biochemical, histological and virological data, have been analysed in patients suffering from chronic hepatitis C (CHC). Patients and methods: serum HGF concentration was measured by ELISA in sandwich in 45 patients with CHC. Correlation between HGF levels and histological (necroinflammatory activity and fibrosis score) and biochemical (transaminases, prothrombin activity, albumin, bilirubin), or virological (hepatitis C virus load) parameters was analyzed. Serum HGF concentration was also studied in a subgroup of the original sample treated with interferon and ribavirin. Results: serum HGF concentrations of patients with CHC were significantly higher than those detected in healthy controls. Patients with significant fibrosis (F ≥ 2) had a significantly older age, lower count of platelets and higher values of AST, GGT and HGF, than those patients with a fibrosis score F < 2. HGF concentration was identified by multivariate analysis as the only independent factor associated with significant fibrosis. Moreover, area under receiver operating curve, using HCG levels, showed similar values to those of previously validated non-invasive indexes of fibrosis. However, levels of HGF did not show a significant decrease in patients with a sustained response to anti-virus C therapy. Conclusion: serum HGF concentration correlates with fibrosis score in patients with CHC, but is insensitive to monitor changes induced by anti-virus C therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
