Unusual extramedullary recurrences and breast relapse despite hepatic GVHD after allografting in Ph+-ALL.

Extramedullary recurrences with or without bone marrow involvement are reported in up to a half of leukemic relapses after BMT. Our report describes a case of an extramedullary recurrence and breast relapse after second-allografting in a female patient with Ph+-acute lymphoblastic leukemia (ALL), occurring when there was active hepatic GHVD. This case illustrates the complex relationship between graft-versus-host disease (GVHD) and graft-versus-leukemia since she had no evidence of leukemia in her marrow demonstrating 100% full-donor chimerism while she had ALL relapse in her breast.

Simvastatin treatment improves endothelial function and increases fibrinolysis in patients with hypercholestrolemia.

OBJECTIVES: Statins reduce cardiovascular events by cholesterol-lowering as well as nonlipid-related actions. Thrombin activatable fibrinolysis inhibitor (TAFI) is a recently identified independent risk factor of thrombosis. Endothelial dysfunction is also a strong predictor of cardiovascular events. The aim of this study was to assess the effects of simvastatin treatment on circulating TAFI concentrations and endothelial function in patients with hypercholesterolemia. METHODS: Thirty-five patients (19 female, mean age 48 +/- 7 years) with hyperlipidemia were recruited into the study. Simvastatin was administered, 40 mg daily, for eight weeks to all subjects. Study subjects did not receive any medication except for lipid-lowering therapy during the follow-up period. Endothelial function was evaluated by flow-mediated dilation (FMD) from the brachial artery of the patients. Plasma lipid parameters, TAFI levels and endothelial function were measured before and after simvastatin treatment. RESULTS: Treatment with simvastatin showed a significant decrement in plasma total cholesterol, LDL cholesterol and triglyceride levels (p<0.05). Plasma TAFI levels were also significantly decreased after simvastatin treatment [median 17.0 (range 0.4-93.7) mcg/mL versus median 6.9 (range 0.8-63.0) mcg/mL, p<0.001]. Mean FMD was measured 7.7 +/- 2.5% at baseline and significantly improved after treatment (13.0 +/- 1.4%) (p=0.001). CONCLUSION: Our findings of decreased TAFI levels may reflect the beneficial effect of simvastatin treatment on fibrinolysis, and improved endothelial function may suggest the improved future cardiovascular events in hyperlipidemic patients.
