The impact of peginterferon alfa-2a plus ribavirin combination therapy on health-related quality of life in chronic hepatitis C

Background/Aims: Peginterferon alfa-2a plus ribavirin improves sustained virological responses compared with interferon alfa-2b and ribavirin, or peginterferon alfa-2a alone in chronic hepatitis C. We examined the impact of these treatments on health related quality of life (HRQOL). Methods: Patients (n = 1121) were randomized to peginterferon alfa-2a weekly plus ribavirin or placebo, or interferon alfa-2b thrice weekly plus ribavirin. HRQOL was assessed with the SF-36 Health Survey and Fatigue Severity Scale (FSS). Results: Patients receiving peginterferon alfa-2a plus ribavirin reported better HRQOL than those receiving interferon alfa-2b plus ribavirin. These differences were statistically significant for three SF-36 domains and both FSS scores (p < = 0.05). Patients receiving peginterferon alfa-2a plus placebo had the least impairment; adding ribavirin significantly decreased five domains of the SF-36 and both FSS scores. Sustained virological response was associated with improvement at follow-up on all SF-36 and FSS scores. Conclusions: The effects of combination therapy on HRQOL and fatigue are less with peginterferon alfa-2a plus ribavirin than interferon alfa-2b plus ribavirin. Each medication in combination therapy with interferon and ribavirin, affects patients' quality of life differently. Understanding the relationship of specific therapeutic options to HRQOL may help physicians minimize the impact of therapy on HRQOL. (C) 2004 European Association for the Study of the Liver.

Topical interferon alfa-2b for the treatment of recalcitrant ocular surface squamous neoplasia

center dot PURPOSE: To evaluate topical interferon alfa-2b (IFN-alpha 2b) for the treatment of recalcitrant ocular surface squamous neoplasia (OSSN). center dot DESIGN: Prospective, noncomparative, interventional consecutive case series. center dot METHODS: Ten patients with recalcitrant OSSN were treated with topical IFN-alpha 2b (1 million IU/ml) four times a day until clinical resolution of the lesion or until the lesion appeared nonresponsive-that is, treatment failure. Progress was assessed by clinical examination and photographic records, with a minimum follow,up of six months. center dot RESULTS: Eight of 10 patients achieved clinical resolution from topical IFN-alpha 2b treatment. One patient developed invasive squamous cell carcinoma and underwent exenteration. The other patient required further mitomycin C therapy to achieve clinical resolution. The mean duration to clinical resolution for the eight patients treated with IFN-alpha 2b was 21.9 weeks (range six to 59 weeks). There have been no recurrences for any of the nine patients during follow-up (mean 55.0 weeks; range 26 to 84 weeks). center dot CONCLUSIONS: Topical IFN-alpha 2b is an important treatment modality for recalcitrant OSSN; it avoids the risks of further limbal stem cell destruction from other agents and surgical excision. If invasive disease is diagnosed at any stage, topical therapy is contraindicated, necessitating surgical excision. (Am J Ophthalmol 2006; 142:568-571. (c) 2006 by Elsevier Inc.

Pro-inflammatory cytokines IL6, TNF-α, IL1β, procalcitonin, lipopolysaccharide binding protein and C-reactive protein in infective endocarditis

Objective: To evaluate the serum levels and diagnostic value of cytokines and acute phase proteins in patients with infective endocarditis (IE). Patients and methods: Serum samples from 63 patients diagnosed with IE and 71 control patients were analysed for the following markers: interleukin-6 (IL6), tumour necrosis factor-α (TNF-α), interleukin 1-β (IL1β), procalcitonin (PCT), lipopolysaccharide binding protein (LBP) and C-reactive protein (CRP). Results: Serum levels of IL6, IL1β and CRP were significantly elevated in patients with IE as compared to controls. PCT, TNF-α and LBP were not elevated. Conclusion: Serum CRP and IL6 are elevated in IE. IL 6 may aid in establishing the diagnosis. There was no correlation between IL 6 levels and CRP, causative microorganism, echocardiographic features or outcome. © 2007 The British Infection Society.
