Item 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-7318-2017Background 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.Item The Impact of Acute Brucellosis on Mean Platelet Volume and Red Blood Cell Distribution(2015) Togan, Turhan; Narci, Huseyin; Turan, Hale; Ciftci, Ozgur; Kursun, Ebru; Arslan, Hande; 25825650Background: Brucellosis is an inflammatory disease which may infect any organs or systems in the body. Mean Platelet Volume (MPV) is one of the most frequently used surrogate markers of platelet function. It reveals the presence of disease activity in many inflammatory diseases. Red blood cell distribution width (RDW) is a parameter that measures variation in red blood cell size or red blood cell volume. Its predictive value approves inflammatory and infectious diseases. Objectives: The current study aimed to determine the assessment levels of red blood cell distribution in cases with acute brucellosis. Patients and Methods: The current study investigated whether MPV and RDW played any roles in acute brucellosis diagnosis. The study was conducted from 2008 to 2014 through prospective examination of the inflammatory markers found in adult patients with acute brucellosis. Results: The follow-up within the year after treatment was examined. The values of age, gender, leukocyte count, C-reactive protein, RDW and MPV were recorded. The study included 351 subjects, 250 of them in the acute brucellosis group and 101 in the control group. The mean MPV levels were 7.64 +/- 1.30 fL, and 7.67 +/- 1.29 fL in the acute brucellosis and control groups, respectively (P > 0.05). The mean CRP levels were 32.57 +/- 53.20 mg/dL, and 4.81 +/- 4.89 mg/dL in the acute brucellosis and control groups, respectively (P < 0.05). There was no statistically significant difference between the two groups regarding the RDW level and the mean leukocyte count (P > 0.05). Conclusions: While the CRP value was in patients with acute brucellosis in the current study, the MPV, RDW and leukocyte counts were within the normal range. CRP value remains the most valuable inflammatory marker in cases of acute brucellosis.Item Osteoarticular Involvement among Brucellosis Cases in Konya City(2015) Ozden, Hale Turan; Togan, TurhanPurpose: Brucellosis is a systemic disease that can affect many organs and tissues. Musculoskeletal system is one of the most commonly affected systems. Disease may present itself with sacroiliitis, peripheral arthritis, spondylitis, paraspinal abscess, bursitis or osteomyelitis. The objective of the present study was to determine the frequency, types and clinical features of osteoarticular involvement among cases with brucellosis in Konya city and to establish the differences between patients with and without osteoarticular involvement. Material and Methods: Three hundred and sixteen patients with Brucellosis who presented between June 2003 and June 2014 were included in the study. Brucellosis was diagnosed by positive Bruce Ila Standard Agglutination Test (1/160 titer) and/or growth of Bruce Ila spp. in blood culture in addition to the presence of clinical signs and findings. Diagnosis of osteoarticular system complications was established by physical examination and radiological findings obtained by diagnostic imaging tools. Magnetic resonance images of the thoracic, lumbar or sacral vertebrae were acquired in patients with back pain, low back pain and sacro-iliac joint pain. Results: Osteoarticular involvement was noted in 129 patients (40.8%) (females: 52% and males: 48%). The most common route of transmission was employment in farming and/or consumption of un-pasteurized milk or dairy products, especially fresh cheese, in 97 (75%) cases. Mean age was 46 18 years. Sacroiliitis was the most frequent osteoarticular involvement (n: 68, 52.7%), 70.5% of which were bilateral. Sacroiliitis was followed by spondylodiscitis in 35 (38.7%), peripheral arthritis in 20 (15.5%), bursitis in 1 (0.8%) cases. Patients with osteoarticular involvement received medical treatment for at least three months. Discussion: Ratio and anatomical region of osteoarticular involvement in brucellosis shows variability among areas. In the present study, we demonstrated that sacroiliitis was the most common form in Konya city. This disease should be included in differential diagnosis in patients with symptoms of sacroiliitis, spondylodiscitis or those with articular pain. Key words: Brucellosis, osteoarticular involvement
