RESUMO
AIM: Venous thromboembolism (VTE) is one of the leading causes of morbidity and mortality in acutely ill medical patients. Fondaparinux is recommended for the prevention of VTE in this setting, but little information is available on its safety and effectiveness in unselected, "real world" patients. The aim of this paper was to assess the safety and efficacy of fondaparinux in elderly acutely ill medical patients. METHODS: Single center, retrospective study. All patients >60 years, admitted for acute medical disease, bedridden for at least four days and treated with fondaparinux were evaluated. Occurrence of objectively documented, symptomatic VTE, and of bleeding events during the treatment period and follow-up were reported. RESULTS: Two hundred and ten patients (median age 81 years) were treated with fondaparinux. Seventy patients received fondaparinux 1.5 mg daily, 140 received the 2.5 mg daily dose. However, 29 patients in the first group (with a CrCl≥50 mL/min) and 84 patients in the last group (with a CrCl<50 mL/min) did not receive the correct dose of fondaparinux. During treatment, one episode (0.48%, 95% CI 0.1% to 2.6%) of major bleeding and 6 episodes (2.86%, 95% CI 1.3% to 6.1%) of clinically relevant non major bleeding were recorded. Only one thromboembolic event (0.48%, 95% CI 0.1% to 2.6%) was documented. Thirty-nine patients died; no death was related to VTE, unlike one death was due to major bleeding. Cancer was the only significant predictor of bleeding at statistical analysis. CONCLUSION: In elderly acutely ill hospitalized medical patients, thromboprophylaxis with fondaparinux 2.5 or 1.5mg daily is safe and effective in preventing VTE without increasing bleeding risk.

BACKGROUND: The non-Hodgkin's lymphoma (NHL) subgroup most frequently associated with hepatitis C virus (HCV) infection is the lymphoplasmacytoid lymphoma/immunocytoma (Lp-Ic). We have assessed the impact of the infection on the clinical features, quality of life and survival of HCV+ve Lp-Ic patients as compared to its impact in HCV-ve patients. PATIENTS AND METHODS: Seventy patients with Lp-Ic consecutively observed over a six-year period were studied. Clinical, virological and histopathological features were recorded at diagnosis. Quality of life was assessed using a scoring system including disease-related symptoms, performance status, working ability, hospital admissions and therapies required. RESULTS: Eighteen patients (26%) with HCV infection were identified. Significant differences between those patients and the HCV-ve group included number of symptomatic patients, Hb levels, serum protein levels, entity of the IgM monoclonal component, number of patients with cryoglobulins and with organ (liver, kidney) involvement, and entity and pattern of bone marrow infiltration. Survival rates were similar (P = 0.8383), but the quality-of-life score was significantly worse for the HCV+ve patients (P = 0.002). All anti-HCV Ab+ve patients tested positive for HCV RNA; genotype 2ac was detected in a significant proportion of cases. CONCLUSIONS: This study confirms that HCV infection is present in about one-third of patients with Lp-Ic. HCV infection does not seem to affect the overall survival of patients with Lp-Ic, but it affects the clinical expression of the disease, so that the overall quality of life of HCV+ve patients is significantly worse.
