A case of eosinophilic myocarditis following high serum levels of eosinophil cationic protein (ECP) is described. A 27 year old woman was admitted with New York Heart Association (NYHA) class III congestive heart failure. A haematological study showed hypereosinophilia with degranulation and vacuoles; the total eosinophil count was 7980/ml and the ECP serum concentration was noticeably high at ...

The aim of this study was to evaluate the clinical and immunomodulatory effects of extracorporeal photochemotherapy (ECP) in systemic sclerosis (SSc). We enrolled 16 patients with diffuse cutaneous SSc, who received 12 ECP treatments in total. After ECP treatments, the dermal thickness reduced and the mobility of joints improved. Internal organ involvement did not deteriorate. The percentages a...

Extracorporeal photochemotherapy (ECP) has been associated with clinical improvement in several patients with acute and chronic graft-versus-host disease (cGVHD) after allogeneic bone marrow transplantation, but the mechanism of action is unknown. This study tested the hypothesis that in patients with cGVHD, ECP modulates alloreactivity by affecting activated lymphocyte populations or by alteri...

The eosinophil granulocyte is an inflammatory cell involved in allergic diseases such as asthma and rhinitis. Eosinophil cationic protein (ECP) is a basic and potentially cytotoxic granule protein that is released from the eosinophil upon activation. The aim was to study secretion of molecular variants of ECP from blood eosinophils with the hypothesis that the stored noncytotoxic ECP is altered...

Extracorporeal photochemotherapy (ECP) has been shown to be an effective therapy for patients with acute and chronic graft-versus-host disease (GVHD) following allogeneic bone marrow transplantation, but its biologic mechanism is not understood. We reported that clinical response to ECP was associated not only with normalization of skewed CD4/CD8 ratios but also with an increase in CD3(-)/CD56(...

BACKGROUND Arteriogenesis (collateral artery growth) is nature's most efficient rescue mechanism to overcome the fatal consequences of arterial occlusion or stenosis. The goal of this trial was to investigate the effect of external counterpulsation (ECP) on coronary collateral artery growth. MATERIALS AND METHODS A total of 23 patients (age 61 +/- 2.5 years) with stable coronary artery diseas...

Extracorporeal photochemotherapy (ECP) is widely used to treat cutaneous T-cell lymphoma, graft-versus-host disease, and allografted organ rejection. Its clinical and experimental efficacy in cancer immunotherapy and autoreactive disorders suggests a novel mechanism. This study reveals that ECP induces a high percentage of processed monocytes to enter the antigen-presenting dendritic cell (DC) ...

BACKGROUND Eosinophil cationic protein (ECP) and eosinophil derived-neurotoxin (EDN) are homologous ribonuclease (RNAse) A family proteins. The objective of the present study was to in silico characterize ECP and EDN with respect to their cytotoxic activities. MATERIALS AND METHODS Structural, physicochemical, and conserved domain characterizations were carried-out using open-source software,...

BACKGROUND The efficacy of external counterpulsation (ECP) on coronary collateral growth has not been investigated in a randomised controlled study. Objective To test the hypothesis that ECP augments collateral function during a 1 min coronary balloon occlusion. PATIENTS AND METHODS Twenty patients with chronic stable coronary artery disease were studied. Before and after 30 h of randomly all...

BACKGROUND An enteric-coated levonorgestrel emergency contraceptive pill (E-LNG-ECP) is an improved formulation, in terms of side effects, which both dissolves and is absorbed in the intestine. Our aim was to evaluate the efficacy and safety of E-LNG-ECP as an over-the-counter (OTC) drug for emergency contraception (EC) in Chinese women. METHODS A Phase IV clinical trial was conducted in five...
