    Does Brucellosis Cause Arterial Stiffness and Ventricular Remodelling Through Inflammation?
    (2015) Togan, Turhan; Ciftci, Ozgur; Gunday, Murat; Narci, Huseyin; Arslan, Hande; 0000-0002-6636-9391; 0000-0002-5708-7915; 0000-0002-6463-6070; 26148379; L-7182-2015; ABG-7034-2021; A-7318-2017
    Background Like other acute and chronic infections, Brucella infection leads to endothelial dysfunction. Furthermore, it has been suggested that the chronic inflammatory state present in chronic infectious diseases leads to an acceleration in atherosclerosis. For the prediction of CAD, it is possible to use epicardial fat thickness (EFT) as an adjunctive marker beside the classical risk factors, as it is easily and non-invasively evaluated by transthoracic echocardiography. The purpose of this study was to investigate the presence of impaired myocardial performance as well as of increased arterial stiffness and EFT in patients who had been infected with brucellosis in the past. Methods Included in the study were twenty-seven brucellosis patients and twenty-six healthy volunteers. Using EFT and transthoracic echocardiography, which included Doppler echocardiography in combination with tissue Doppler imaging (TDI), all the patients were examined to measure their aortic stiffness index (AoSI), aortic distensibility (AoD), and aortic elastic modulus (AoEM) values. Results A statistically significant increase was observed in hs-CRP, aortic stiffness index, aortic elastic modulus and EFT in brucellosis patients when compared with the controls (2.46 +/- 1.40 vs 1.71 +/- 0.61, P=0.016; 9.69 +/- 6.99 vs 2.14 +/- 0.72, P < 0.001; 11.17 +/- 8.60 vs 2.18 +/- 0.90, P < 0.001; 0.76 +/- 0.08 vs 0.63 +/- 0.10, P < 0.001). On the other hand, there was a significant decrease in aortic strain and aortic distensibility (7.41 +/- 6.82 vs 18.26 +/- 5.83, P < 0.001; 1.83 +/- 1.71 vs 5.22 +/- 1.72, P < 0.001, respectively). No difference was observed between the two groups with respect to the left ventricular myocardial performance index (MPI) (0.62 +/- 0.15 vs 0.61 +/- 0.13, P=0.859). Conclusions In this study, we demonstrated for the first time in the literature that there was impaired aortic elasticity and increased EFT in patients with brucellosis, while the myocardial performance index remained unaffected. We also determined that these effects had a significant correlation with inflammation.

    Does mild preeclampsia cause arterial stiffness and ventricular remodeling through inflammation?

    Background: A link between preeclampsia (PE) and excessive maternal morbidity and mortality is a commonly recognized fact. Moreover, it has been suggested that chronic inflammatory state connected with PE contributes to accelerated atherosclerosis. There is also an association between PE and maternal cardiac remodeling and biventricular diastolic dysfunction. The aim of the study was to investigate the presence of impaired myocardial performance and increased arterial stiffness in patients who experienced a mild case of PE five years previously. Methods: The study included forty PE patients (40 women; mean age 33.75 +/- 7.95) and 27 healthy volunteers (27 women; mean age 36.44 +/- 10.45) Transthoracic echocardiography, including Doppler echocardiography combined with tissue Doppler imaging (TDI), and aortic stiffness index (AoSI), aortic distensibility (AoD), and aortic elastic modulus (AoEM) values were measured in each study participant. Results: There was a statistically significant increase in hsCRP, aortic stiffness index, and aortic elastic modulus in PE patients as compared to controls (2.43 +/- 1.91 vs. 3.80 +/- 2.06, p=0.007; 3.09 +/- 2.41 vs. 7.32 +/- 6.89, p=0.001; 2.89 +/- 2.11 vs. 7.00 +/- 6.83, p=0.001), while a significant decrease was observed in the aortic strain and distensibility (respectively, 22.35 +/- 15.99 vs. 12.24 +/- 9.22, p=0.005; 11.17 +/- 9.68 vs. 6.13 +/- 4.99, p=0.018). No differences between the two groups were observed with regard to the left ventricular myocardial performance index (MPI) (0.55 +/- 0.16 vs. 0.53 +/- 0.19, p=0.630). Conclusions: To the best of our knowledge, this has been the first study to demonstrate impaired aortic elasticity and unaffected myocardial performance index in patients with mild PE. Moreover, these effects turned out to be significantly correlated with inflammation.
