The value of serum tumour markers in the prediction of aetiology and follow up of patients with pericardial effusion.

BACKGROUND: The aim of this study was to evaluate the value of tumour markers in the differential diagnosis of pericardial effusions and to assess their changing levels during follow up. METHODS: Sixty-nine patients who were admitted to hospital with a diagnosis of pericardial effusion were included in the study. Serum tumour markers were measured on admission and after a mean of 18 ± 7 months' follow up. An aetiological diagnosis was made on clinical evaluation, imaging techniques and biochemical, microbiological and pathological analysis. The patients were divided into five groups according to the aetiology of their pericardial effusions. RESULTS: Carbohydrate antigen (CA) 12-5 and CA 15-3, and carcinoembryonic antigen (CEA) levels were significantly higher in patients with malignancies than in those with viral/idiopathic pericarditis. With multivariate analysis, CA 15-3 levels were found to be the most significant determinant (p = 0.027). In the ROC curve analysis, CA 15-3 values above 25 U/ml predicted a malignancy with 71% sensitivity and 78% specificity. CONCLUSION: Tumour markers, particularly CA 15-3, may be useful in the differential diagnosis and prediction of malignancies in patients with pericardial effusion. In patients with viral/idiopathic aetiology, these serum tumour markers were slightly elevated in the acute phase, but after a mean of one year of follow up, their levels returned to normal, contrary to those with malignancies.

Biventricular involvement in a Turkish boy with palmoplantar hyperkeratosis and curly hair, an unusual presentation of Naxos-Carvajal syndrome.

Naxos disease is an autosomal recessively inherited familial syndrome characterized by woolly hair, palmoplantar keratoderma and a cell adhesion cardiomyopathy, especially arrhythmogenic right ventricular dysplasia (ARVD). Carvajal syndrome is a variant of Naxos disease in which curly or woolly hair, biventricular--predominantly left ventricular involvement were seen. Mutations in genes encoding the cell adhesion proteins like plakoglobin and desmoplakin were related with these syndromes. We report a 17-year-old boy and his family findings with curly hair, palmoplantar hyperkeratosis, ARVD and left ventricular involvement. The family was of Arabic origin, and a third-degree consanguinity was reported between the parents. They are from east part of Turkey and there were no relatives from Cyclades Island (Greece). Patient's younger brother had ARVD without cutaneous manifestations of the syndrome and his grand father had mild ARVD, curly hair and palmoplantar hyperkeratosis.

Relation between proinflammatory to anti-inflammatory cytokine ratios and long-term prognosis in patients with non-ST elevation acute coronary syndrome.

OBJECTIVE: To investigate the relation between serum high sensitivity (hs) C reactive protein (CRP), proinflammatory cytokine concentrations, proinflammatory to anti-inflammatory cytokine ratios and long-term prognosis in patients with non-ST elevation acute coronary syndrome (NSTEACS). DESIGN: Prospective follow-up study for the first six months and then for the first year after admission to hospital. SETTING: Tertiary referral centre. PATIENTS: 80 patients (60 men, 20 women, mean age 60 (SD 10) years) with NSTEACS and moderate to high TIMI (Thrombolysis In Myocardial Infarction) risk scores. INTERVENTIONS: Blood samples from patients with NSTEACS were obtained at the time of admission. Serum concentrations of hs-CRP, (hs) pro-inflammatory (interleukin (IL) -1beta, IL-6, tumour necrosis factor alpha) and (hs) anti-inflammatory (IL-10) cytokines were analysed and proinflammatory to anti-inflammatory cytokine ratios were calculated by dividing proinflammatory cytokine concentrations by anti-inflammatory cytokine IL-10. MAIN OUTCOME MEASURE: The primary end point of the study was new coronary events (NCE) defined as the combination of cardiac death, non-fatal myocardial infarction and recurrent rest angina that required hospitalisation within 12 months of follow up. RESULTS: During the one-year follow-up period, 23 patients (29%) met the NCE criteria. Concentrations of hs-CRP, IL-1beta and IL-6 and ratios of IL-1beta:IL-10 and IL-6:IL-10 were significantly higher in patients with NCE than in patients without NCE. In the logistic regression analysis, IL-6:IL-10 ratio was the most important predictor for NCE (p = 0.006) with an odds ratio of 2.24 (95% CI 1.26 to 3.97). CONCLUSIONS: Cytokine concentrations and proinflammatory to anti-inflammatory cytokine ratios may be useful markers for predicting vascular risk in patients with NSTEACS.

[Relation of HLA antigens and myocardial infarction]. / Akut miyokard infarktüsü ile HLA doku grubu iliskisi.

OBJECTIVE: Genetic predisposition and chronic inflammation play the leading role in the early stages and in the development of atherosclerosis. Previous studies have shown that substantial amounts of T-lymphocytes are present in both early fatty lesions and advanced fibrous lesions in humans. This observation suggests that HLA antigens may be used as genetic markers for the tendency to coronary artery disease. The aim of our study was to investigate the relation of atherosclerosis and HLA antigens in patients with acute myocardial infarction. METHODS: Thirty consecutive patients with acute myocardial infarction (15 male, 15 female, aged 54+/-8 years) and 30 subjects (15 male, 15 female, aged 52+/-7 years) without evidence of coronary artery disease--according to physical, fundoscopic, electrocardiographic and radiological examination--were enrolled to the study. Histocompatibility antigens (HLA-AB, -DR, -DQ) were studied with lymphocytotoxicity method. RESULTS: Age, gender, smoking, alcohol consumption, frequency of obesity and diabetes mellitus were similar between the two groups. In patients with myocardial infarction frequency of hypertension, family history and hyperlipidemia were significantly higher than the controls (p < 0.0003, p < 0.0001, p < 0.01 respectively). Frequency of HLA antigens in patients and in controls was 50% and 23% for HLA-A2, 63% and 20% for HLA-DQ4 and 90% and 50% for HA-DQ7. Logistic regression analysis revealed a significant relation with the disease and the presence of these antigens (p = 0.02, p = 0.02 and p = 0.03 respectively). CONCLUSIONS: It is concluded that in the Turkish population presence of HLA-A2, HLA-DQ4 ve HLA-DQ7 (3) may be used as genetic markers for the tendency to coronary artery disease.
