Identificazione e dosaggio di marcatori molecolari dell'endometriosi nel sangue periferico

Purpose: to quantify the mRNA levels of MMP-3, MMP-9, VEGF and Survivin in peripheral blood and the serum levels of CA-125, Ca19-9 in women with and without endometriosis and to investigate the performance of these markers to differentiate between deep and ovarian endometriosis. Methods: a case controls study enrolled a series of 60 patients. Twenty controls have been matched with 20 cases of ovarian and 20 cases of deep endometriosis. Univariable and multivariable performance of serum CA125 and CA19-9, mRNA for Survivin, MMP9, MMP3 and VEGF genes have been evaluated by means of ROC curves and logistic regression respectively. Results: No difference in markers concentration were detected between ovarian and deep endometriosis. In comparison with controls serum CA19 and CA125 yielded the better sensitivity followed by mRNA for Survivin gene (81.5%, 51.9% and 7.5% at 10% false positive rate respectively). Multivariable estimated odds of endometriosis yielded a sensitivity of 87% at the same false positive rate. Conclusions: A combination of serum and molecular markers could allow a better diagnosis of endometriosis.

Left Ventricle Modification After Endovascular Aortic Repair

INTRODUCTION Endograft deployment is a well-known cause of arterial stiffness increase as well as arterial stiffness increase represent a recognized cardiovascular risk factor. A harmful effect on cardiac function induced by the endograft deployment should be investigated. Aim of this study was to evaluate the impact of endograft deployment on the arterial stiffness and cardiac geometry of patients treated for aortic aneurysm in order to detect modifications that could justify an increased cardiac mortality at follow-up. MATHERIALS AND METHODS Over a period of 3 years, patients undergoing elective EVAR for infrarenal aortic pathologies in two university centers in Emilia Romagna were examined. All patients underwent pre-operative and six-months post-operative Pulse Wave Velocity (PWV) examination using an ultrasound-based method performed by vascular surgeons together with trans-thoracic echocardiography examination in order to evaluate cardiac chambers geometry before and after the treatment. RESULTS 69 patients were enrolled. After 36 months, 36 patients (52%) completed the 6 months follow-up examination.The ultrasound-based carotid-femoral PWV measurements performed preoperatively and 6 months after the procedure revealed a significant postoperative increase of cf-PWV (11,6±3,6 m/sec vs 12,3±8 m/sec; p.value:0,037).Postoperative LVtdV (90±28,3 ml/m2 vs 99,1±29,7 ml/m2; p.value:0.031) LVtdVi (47,4±15,9 ml/m2 vs 51,9±14,9 ml/m2; p.value:0.050), IVStd (12±1,5 mm vs 12,1±1,3 mm; p.value:0,027) were significantly increased if compared with preoperative measures.Postoperative E/A (0,76±0,26 vs 0,6±0,67; p.value:0,011), E’ lateral (9,5±2,6 vs 7,9±2,6; p.value:0,024) and A’ septal (10,8±1,5 vs 8,9±2; p.value0,005) were significantly reduced if compared with preoperative measurements CONCLUSION The endovascular treatment of the abdominal aorta causes an immediate and significant increase of the aortic stiffness.This increase reflects negatively on patients’ cardiac geometry inducing left ventricle hypertrophy and mild diastolic disfunction after just 6 months from endograft’s implantation.Further investigations and long-term results are necessary to access if this negative remodeling could affect the cardiac outcome of patient treated using the endovascular approach.
