BACKGROUND We investigated clinical effects of intracoronary transplantation of CD34+ cells in patients with dilated cardiomyopathy (DCM). METHODS Of 55 patients with DCM, 28 were randomized to CD34+ transplantation (SC group), and 27 patients did not receive stem cell therapy (controls). In the SC group, peripheral blood CD34+ cells were mobilized by(More)
RATIONALE CD34+ transplantation in dilated cardiomyopathy was associated with short-term improvement in left ventricular ejection fraction and exercise tolerance. OBJECTIVE We investigated long-term effects of intracoronary CD34+ cell transplantation in dilated cardiomyopathy and the relationship between intramyocardial cell homing and clinical response.(More)
BACKGROUND In an open-label blinded study, we compared intracoronary and transendocardial CD34(+) cell transplantation in patients with nonischemic dilated cardiomyopathy. METHODS AND RESULTS Of the 40 patients with dilated cardiomyopathy, 20 were randomized to receive intracoronary injection and 20 received transendocardial CD34(+) cell delivery. In both(More)
PURPOSE Primary hyperparathyroidism is a common endocrine disorder which is diagnosed biochemically and for which therapy is surgical. A prerequisite for minimally invasive surgery, which minimizes morbidity and cost, is accurate localization of the involved gland(s). The aim of this study was to evaluate the usefulness of (18)F-fluorocholine PET/CT for(More)
BACKGROUND Parathyroid adenomas, the most common cause of primary hyperparathyroidism, are benign tumours which autonomously produce and secrete parathyroid hormone. [(18)F]-fluorocholine (FCH), PET marker of cellular proliferation, was recently demonstrated to accumulate in lesions representing enlarged parathyroid tissue; however, the optimal time to(More)
Inflammation plays a major pathogenetic role in the development of atherosclerotic plaques and related thromboembolic events. The identification of vulnerable plaques is of the utmost importance, as this may allow the implementation of more effective preventive and therapeutic interventions. Fluorodeoxyglucose positron emission tomography (FDG-PET) has been(More)
OBJECTIVE To determine factors influencing radioguided surgery of neuroendocrine tumours using Tc-ethylenediamine N,N'-diacetic acid/6-Hydrazinopyridine-3-carboxylic acid-D-Phe-Tyr-octreotide and gamma-probe. METHODS Patients with 17 neuroendocrine tumours were operated on. Three to 6 h before surgery, 550-650 MBq of Tc-labelled octreotide were injected(More)
BACKGROUND We investigated the effects of intracoronary transplantation of CD34(+) cells on myocardial perfusion in patients with nonischemic dilated cardiomyopathy (DCM). METHODS AND RESULTS We enrolled 21 patients with DCM (left ventricular ejection fraction [LVEF] <40%, New York Heart Association functional class III) who underwent peripheral stem cell(More)
BACKGROUND Although stem cell therapy (SCT) is emerging as a potential treatment for patients with dilated cardiomyopathy (DCM), clinical response remains variable. Our objective was to determine whether baseline differences in circulating immunologic and nonimmunologic biomarkers may help to identify patients more likely to respond to intramyocardial(More)
AIM Inflammation is highlighted in the pathogenesis and destabilization of atherosclerotic lesions. Noninvasive identification of inflammation of atherosclerotic lesions has been challenging. 18-Fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) is a useful technique for detecting inflamed atherosclerotic plaques in vivo. However, it is time(More)
