Favorable long-term follow-up results over 6 years for response, survival, and safety with imatinib mesylate therapy in chronic-phase chronic myeloid…
2008
Abstract Imatinib mesylate, a targeted inhibitor of BCR-ABL tyrosine kinase, is the standard of care for chronic myeloid leukemia (CML). A phase 2 trial of imatinib in late chronic-phase (CP) CML after interferon-α (IFNα) failure enrolled 532 patients, 454 with a confirmed diagnosis of CP CML. Median time from diagnosis was 34 months; median duration of imatinib treatment was 65 months. Cumulative best rates of major cytogenetic response (MCyR) and complete cytogenetic response (CCyR) were 67% and 57%, respectively. At the 5-year landmark, 184 (41%) of the 454 patients are in CCyR. At more than 6 years, 199 (44%) of the 454 patients remain on imatinib. Most responses occurred within 12 mont…
Long-term outcome of treatment with dacarbazine, cisplatin, interferon-α and intravenous high dose interleukin-2 in poor risk melanoma patients
1998
Melanoma patients with very advanced disease are usually excluded from chemoimmunotherapy trials; however, the efficacy of intensive treatment regimens needs to be established for this patient population. This study aimed to evaluate the response rate and survival achieved with chemoimmunotherapy in very advanced melanoma patients. Forty-two patients received dacarbazine (250 mg/m2, days 1-3), cisplatin (30mg/m2, days 1-3), interferon-alpha (10 Mio IU/m2 subcutaneously, days 1-5) and intravenous interleukin-2 (18 Mio IU/m2 over 6 h, 12 h then 24 h, followed by 13.5 MioIU/m2 in 72 h). In cases of brain metastases (n = 12) radiation therapy was added. Ten patients (24%) achieved a partial res…
Serum malondialdehyde: possible use for the clinical management of chronic hepatitis C patients
1998
Serum lipid peroxidation products are increased in inflammatory liver disease and, as we previously reported, also in chronic hepatitis C. We have performed a specific assay of malondialdehyde, the reported most abundant product of lipid peroxidation, in serum of twenty four chronic hepatitis C patients, before, during, and after interferon treatment. Liver biopsies were performed in each patient before and after interferon treatment. The results show higher serum malondialdehyde values in chronic hepatitis C patients than healthy subjects (n = 68) before interferon treatment (p < .001). Mean value of serum malondialdehyde levels after interferon treatment was significantly lower than befor…
Duration of HCV infection as a predictor of nonresponse to interferon
1996
Duration of hepatitis C virus (HCV) infection is a key feature in determining responsiveness to interferon (IFN). Studies assessing its value as a predictive factor in chronic HCV infection show that a long duration of infection reduces the likelihood of a sustained response to IFN (defined as ALT normalization and clearance of serum HCV-RNA). The effect of HCV infection duration is independent of the presence of cirrhosis and level of HCV viremia. Meta-analysis of IFN trials in acute HCV infection shows an obvious effect of the drug on long-term ALT normalization and HCV-RNA clearance. Treatment of HCV infection during the acute or early chronic phase could therefore maximize therapeutic e…
Effects of in vitro treatment with fluticasone propionate on natural killer and lymphokine-induced killer activity in asthmatic and healthy individua…
2001
Background: Topical corticosteroids are beneficial in the treatment of allergic respiratory disorders; they exert effects on a number of cells involved in allergic inflammatory reactions. On the other hand, major histocompatibility complex (MHC)-unrestricted cytotoxicity (i.e., natural killer [NK] cell activity) may play a role in the inflammatory allergic reaction. The objective was to gain insight into the mechanisms of the therapeutic effects of fluticasone propionate (FP), an inhaled corticosteroid used in asthma and rhinitis therapy. Therefore, we evaluated the NK and lymphokine-activated killer (LAK) activity of effector cells in vitro treated or not with FP. Methods: Evaluations were…
Faldaprevir (BI 201335), BI 207127 and ribavirin oral therapy for treatment-naive HCV genotype 1: SOUND-C1 final results
2013
Background Faldaprevir (BI 201335) and deleobuvir (BI 207127) are direct-acting antiviral agents under development for the treatment of chronic HCV infection. This article describes the final results of the Phase Ib SOUND-C1 study that evaluated the interferon-free oral combination of faldaprevir, deleobuvir and ribavirin in 32 treatment-naive patients infected with HCV genotype 1. Methods Patients were randomized to receive deleobuvir 400 mg ( n=15) or 600 mg ( n=17) three times daily plus faldaprevir 120 mg once daily and weight-based ribavirin for 4 weeks. Interferon-free therapy was followed by response-guided faldaprevir plus pegylated interferon-α2a/ribavirin to week 24 or 48. Results…
The HCV Sicily Network: A web-based model for the management of HCV chronic liver diseases
2016
Epidemiological studies report that in Sicily reside about 30,000 citizens with a diagnosis of chronic hepatitis due to HCV. The availability of direct antiviral action (DAA) is a real therapeutic breakthrough, but the high cost of the therapeutic regimes limits their use and forced the National Health System to establish clinical priority for the treatment.The HCV Sicily Network is a web-based model of best medical practice, which was designed to improve the management and the treatment of HCV chronic hepatitis and cirrhosis. The network includes 41 centers and 84 gastroenterologists or infectivologists connected by a web platform that recorder the diagnosis and the clinic priority for the…
Maladaptive and adaptive emotion regulation through music a behavioral and neuroimaging study of males and females
2015
Music therapists use guided affect regulation in the treatment of mood disorders. However, self-directed uses of music in affect regulation are not fully understood. Some uses of music may have negative effects on mental health, as can non music regulation strategies, such as rumination. Psychological testing and functional magnetic resonance imaging (fMRI) were used explore music listening strategies in relation to mental health. Participants (n = 123) were assessed for depression, anxiety and Neuroticism, and uses of Music in Mood Regulation (MMR). Neural responses to music were measured in the medial prefrontal cortex (mPFC) in a subset of participants (n = 56). Discharge, using music to…
Proliferative response of CD4+ T cells and hepatitis B virus clearance in chronic hepatitis with or without hepatitis B e-minus hepatitis B virus mut…
1995
To assess the significance of cell-mediated immunity, T cells were derived from the peripheral blood and liver tissue of hepatitis B virus (HBV)-infected patients and controls. The analysis of the 3H-thymidine-uptake in response to a panel of recombinant HBV antigens revealed that peripheral blood mononuclear cells (PBMC) of the 25 viremic patients with inflammatory active, chronic hepatitis B, 16 with wild-type and nine with HBe-minus HBV mutant infection, showed stronger proliferative responses to HBc and HBe antigens than 16 asymptomatic nonviremic HBsAg carriers with normal aminotransferase levels (HBc: SI 19.3 +/- 3.9 vs. 13.0 +/- 3.2 vs. 8.0 +/- 1.2; P.01 and HBe: SI 16.6 +/- 4.0 vs. …
Hematopoietic Growth Factors Are Differentially Regulated in Monocytes and CD4+T Lymphocytes: Influence of IFN-α and Interleukin-4
1998
We investigated the influence of interferon-alpha (IFN-alpha) on the synthesis of granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3) by monocytes and activated T helper cells. IFN-alpha inhibited the production of GM-CSF in unstimulated and lipopolysaccharide (LPS)-activated monocytes to the same extent as was observed in the presence of IL-4. In highly purified CD4+ T cells, which were activated by incubation with immobilized anti-CD3 antibody and anti-CD28, IFN-alpha reduced production of GM-CSF to 47%. In contrast, GM-CSF production in activated T cells was unaffected by exogenously added IL-4. The production of IL-3 by T helper cells was significantly inh…
