Öğe C-reactive protein and immunoglobulin-E response to coronary artery stenting in patients with stable angina(Japan Heart Journal, Second Dept Of Internal Med, 2003) Erdogan, O; Altun, A; Gul, C; Ozbay, GRecent reports indicate that inflammatory mechanisms play a crucial role in the patho-genesis of atherosclerosis and neointimal proliferation as well as coronary restenosis. To provide baseline data for further Studies regarding stenting, restenosis and inflammatory response, we prospectively conducted a clinical study to investigate the time related response of plasma levels of immunoglobulin-E (IgE) and C-reactive protein (CRP) which are two different inflammatory markers mediated by different cytokines in stable patients who underwent elective coronary artery stenting. Thirteen consecutive stable patients who underwent coronary artery stenting were included in the Study. Levels of I-E and CRP were determined pre- and poststent implantation on four consecutive days and at the end of the first as well as third month. Levels of these two markers were gradually elevated on postprocedure days while reaching peak values oil the second and third days for IgE (initial 278 335 IU/mL vs peak 350 489 IU/mL, P = 0.01) and CRP (initial 0.5 +/- 0 mg/dL vs peak 2.7 +/- 3 mg/dL, P = 0.002), respectively. High levels gradually returned to baseline values determined at the end of the first and even third months after stent implantation implying an acute inflammatory reaction. Stent implantation seems not to cause any persistent and ongoing inflammatory response in the long term.Öğe Increased immunoglobulin E response in acute coronary syndromes(Westminster Publ Inc, 2003) Erdogan, O; Gul, C; Altun, A; Ozbay, GThe role of inflammation and mast cell activation has been implicated in atherosclerotic plaque destabilization and rupture. To investigate the role of immunoglobulin E (IgE) in acute coronary syndrome, a prospective clinical study was conducted in patients with acute myocardial infarction (AMI), unstable angina pectoris (UAP), stable angina pectoris (SAP), and healthy controls. IgE levels were serially measured and compared in consecutive patients with AMI (n = 16) and UAP (n= 14) on days 1, 3, 7, 21 after admission and 3 months later and only once in stable angina pectoris (n = 15) and healthy controls (n = 14). In addition, blood eosinophil and basophil levels on admission were measured in all groups and compared. Initial IgE levels determined at admission in patients with AMI, UAP, and SAP were significantly higher than levels in the control group (p=0.002). Initial high IgE level in AMI on day I increased to a peak by day 7 (p = 0.024), then gradually decreased by day 21 and at 3 months (p = 0.052). High IgE level in UAP persisted by day 7 and gradually decreased by day 21 and 3 months (p = 0.037 and p = 0.018, respectively). Blood eosinophil count on admission was significantly higher in UAP than in the control group (p = 0.005). Basophil levels of both AMI and UAP groups on admission were found to be elevated as opposed to control group (p = 0.02 and p = 0.012, respectively). This study demonstrates that the level of IgE significantly increased during the acute phase of acute coronary syndromes and gradually decreased, supporting the role of acute inflammatory response and mast cell involvement in plaque rupture.Öğe Management of a patient with active rheumatoid arthritis and suspected tuberculosis causing effusive-constrictive pericarditis(Elsevier Sci Ireland Ltd, 2003) Yildiz, M; Erdogan, O; Aktoz, M; Gul, C; Ozbay, GIn the following case report we present a patient who has been admitted for pericardial effusion causing cardiac compression with active rheumatoid arthritis and suspected tuberculosis. The patient was successfully treated with intravenous pulse steroid for active rheumatoid arthritis, with prophylactic anti-tuberculosis agents for suspected tuberculosis and with surgical pericardiectomy for the thickened pericardium as well as recurrent pericardial effusion.
