Results: A total of 25 patients were included between March 2009 and November 2010. Of the 24 patients who had echocardiograms available for reread, there was a response in 20 of 24 patients with normalization of cardiac index (complete response [CR]) in 3 of 24, partial response (PR) in 17 of 24, and no response in 4 cases. Median cardiac index at beginning of the treatment was 5.05 L/min/m2 (range, 4.1-6.2) and significantly decreased at 3 months
buy MG-132 after the beginning of the treatment with a median cardiac index of 4.2 L/min/m2 (range, 2.9-5.2; P = .001). Median cardiac index at 6 months was significantly lower than before treatment (4.1 L/min/m2; range, 3.0-5.1). Among 23 patients with available data at 6 months, we observed CR in 5 cases, PR in 15 cases, and no response in 3 cases. Mean duration of epistaxis, which was 221 minutes per month (range, 0-947) at inclusion, had significantly decreased
at 3 months (134 minutes; range, 0-656) and 6 months (43 minutes; range, 0-310) (P = .008). Quality of life had significantly improved. The most severe adverse events were 2 cases of grade 3 systemic hypertension, which were successfully treated. Conclusion: In this preliminary study of patients with HHT associated with severe hepatic vascular malformations and high cardiac check details output, administration of bevacizumab was associated HCS assay with a decrease
in cardiac output and reduced duration and number of episodes of epistaxis. Dupuis-Girod et al.1 in France recently reported the results of a phase 2 preliminary study demonstrating the efficacy of bevacizumab, a vascular endothelial growth factor (VEGF) inhibitor in patients with hereditary hemorrhagic telangiectasia (HHT) and liver vascular malformations (LVMs) leading to symptomatic heart failure. HHT is a hereditary illness characterized by arteriovenous malformations (AVMs) in many organs. Small LVMs are present in upwards of 70% of patients with HHT, but are usually asymptomatic and detected only on imaging studies.2 However, LVMs large enough to cause symptoms can occur in ∼8% of HHT patients.3, 4 The most common clinical presentation is heart failure resulting from significant hepatic artery to hepatic vein shunting, which leads to excessively high cardiac output (Fig. 1).4, 5 Symptomatic heart failure occurs most commonly in women in their 6th and 7th decades.4, 5 This high output type of heart failure often manifests as exertional fatigue and dyspnea, and can be diagnosed in the presence of a characteristic triad of a wide arterial pulse pressure, systolic murmur, and liver bruit.
