The link between chronic hepatitis C virus (HCV) infection and a subset of B-cell non-Hodgkin lymphomas (B-NHL) is strongly supported by epidemiological studies. Evidence demonstrating complete regression of lymphoma after antiviral treatments suggests possible chronic antigenic stimulation for the origin of B-NHL and provides evidence for a virus-mediated lymphomagenesis. B-NHL is a heterogeneous group of lymphomas with varied clinical presentation and may be indolent or aggressive. The optimal management of HCV related B-NHL is not clear. Antiviral treatment may be sufficient for low-grade lymphomas, but chemotherapy is necessary in patients with high grade lymphomas. Interferon (IFN)-based antiviral treatment regimens for HCV infection are limited by poor tolerance and suboptimal antiviral response. Recently approved novel direct acting antiviral (DAA) drugs are highly effective and safe. This has opened a new era for the treatment of HCV related B-NHL alone or in conjunction with chemotherapy. Treatment of HCV associated B-NHL should be performed in an interdisciplinary approach in close consultation with hematologist and hepatologist. In this review, we summarize data regarding clinical features and epidemiology of B-NHL and discuss novel therapeutic approaches, including DAAs, that may prove to be effective in the treatment of HCV associated lymphomas. 相似文献

Background
The majority of patients with schizophrenia live with their relatives in Pakistan, thereby families experience a considerable burden. We aimed to study the impact of psychoeducation on the burden of schizophrenia on the family in a randomised controlled trial. 相似文献216.

Aspergillus-derived inhalant allergens play an important role in the etiology of allergic respiratory diseases. In the present study, we investigated the allergenic potential of Aspergillus tamarii, quantified its airborne content, identified its major/minor allergens, evaluated heterogeneity of patients’ IgE response to its allergens and cross-reactivity of its allergens with other Aspergillus allergens. Skin prick tests with A tamarii extract were performed on 300 patients of bronchial asthma/allergic rhinitis and 20 healthy volunteers. Sixty-six patients (22%) elicited positive cutaneous reactions to A tamarii extract. Only one of the 20 non-allergic healthy volunteer showed a mild positive cutaneous reaction. Allergen-specific IgE levels increased with increase in patients’ cutaneous response (0% in negative to 100% in 3+/4+). The skin positivity and allergen-specific IgE levels were significantly higher in patients compared to healthy volunteers (P > 0.05). However, no differences were found for these two parameters among patients of bronchial asthma, allergic rhinitis and bronchial asthma with allergic rhinitis. The airborne A tamarii allergen content was highest in February and October. A tamarii extract revealed at least 22 proteins (13.3-120 kDa). Seventeen of these proteins bound patients’ IgE with six being major allergens (13.3, 23, 25, 34, 39.5, 43 kDa). Three major allergens (13.3, 34, 43 kDa) were found to cross-react with A flavus and one (34 kDa) with A niger. Our results revealed that A tamarii allergen(s) are present in the air, which might serve as important inhalant allergens in IgE-mediated allergic respiratory diseases. 相似文献
