AIMS The aim of this retrospective study was to investigate the correlation between MPV and the clinical disease activity indices of rheumatoid arthritis and ankylosing spondylitis. METHODS The study consisted of 32 active RA patients (males/females: 7/25, mean age: 49+/-13) and 30 active AS patients (males/females: 15/15, mean age: 36+/-12) along with 26 osteoarthritis (OA) patients (males/females: 4/22, mean age: 52+/-8) and 29 age-matched healthy subjects (males/females: 5/24, mean age: 41+/-7) as control groups for RA and AS, respectively. RESULTS MPV was significantly lower in both AS patients and RA patients with active disease as compared to controls (RA vs OA p<0.001, AS vs healthy subjects p<0.001). After treatment MPV values significantly increased in AS and RA (p<0.001 for all). However, MPV values remained somewhat lower in RA patients than OA patients (p=0.019). There was a negative correlation between MPV values and BASDAI scores in AS patients after two months of treatment (r=-0.507; p=0.004). CONCLUSION Our results suggest that assessment of MPV may provide additional information about inflammation in AS and RA.

Background: Cardiac involvement is one of the major problems in systemic sclerosis (SSc). Subclinical cardiac involvement has a higher frequency than thought previously. In this study we investigated whether subclinical cardiac involvement can be detected by using echocardiographic strain imaging in SSc patients without pulmonary hypertension. Methods: Echocardiographic examinations were performed to 27 SSc patients and 26 healthy controls. Left ventricular strain parameters were obtained from apical views and average strain value was calculated from these measurements. Results: There were no significant differences between patients and controls regarding two‐dimensional (2D), conventional Doppler and tissue Doppler velocity measurements. Strain was reduced in 6 of 12 segments of the left ventricle (LV) and in 1 of 2 segments of the right ventricle (RV). Strain rate (SR) was reduced in 2 of 12 segments of the LV and 1 of 2 segments of the RV in SSc patients as compared to controls (P < 0.05 for all). These involvements did not match any particular coronary artery distribution. More important differences were detected by average strain and SR values of the LV between patients and controls (19.78 ± 3.00% vs 23.41 ± 2.73%, P < 0.001; 2.01 ± 0.41 vs 2.23 ± 0.27/sec, P = 0.026, respectively). Furthermore, carbon monoxide diffusion capacity (DLCO) in scleroderma patients significantly correlated with LV average strain (r = 0.59; P = 0.001). Conclusion: Evaluation of ventricular function by using echocardiographic strain imaging appears to be useful to detect subclinical cardiac involvement in SSc patients with normal standard echocardiographic and tissue Doppler velocity findings.

Patients with rheumatoid arthritis (RA) have an increased risk of infection as a result of alterations in immune regulation, debility, and comorbid illnesses. TNF-α is of central importance in the pathophysiological responses to infection and inflammation, and plays a crucial role in host defence. Pneumocystis carinii is an opportunistic pathogen that commonly affects individuals with inadequate T-cell mediated immune response. Patients with acquired immune deficiency, as well as those receiving immunosuppressive drugs for various conditions have an increased risk of P. carinii pneumonia (PCP). We report the development of PCP in a woman with RA shortly after the initiation of anti-TNF-α treatment with adalimumab.

This study aimed to assess the frequency of all palpable lymph nodes during active disease and remission in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Hospital records of 100 SLE patients, 100 RA patients, 100 spondyloarthropathy patients, and 150 osteoarthritis patients, treated in our rheumatology department, were evaluated retrospectively. Overall frequencies of enlarged lymph nodes in patients with active RA and SLE were 82% and 69%, respectively. Enlarged lymph nodes associated with RA were mostly located in the axillary region, and in SLE the nodes were smaller and lymphadenopathy was more generalized compared with RA. Palpable lymph nodes disappeared in the majority of patients during remission. Lymphadenopathy was significantly less frequent in patients treated with steroids before admission. Lymph node enlargement is an important physical finding associated with RA and SLE disease activity. Atypical locations and unusually large lymph nodes should raise clinical suspicion of another underlying disease.

Background: Atrial conduction abnormalities in patients with scleroderma have not been evaluated in terms of P wave duration, P wave dispersion (Pd) and electromechanical coupling measured by tissue Doppler echocardiography. Methods: Twenty-four patients with scleroderma and 24 control subjects underwent resting electrocardiogram (ECG), M mode and tissue Doppler echocardiography. The P wave duration was calculated in all leads of the surface ECG. The difference between the maximum (Pmax) and minimum P wave duration was calculated and defined as Pd. Interatrial and intraatrial electromechanical delays were measured with tissue Doppler tissue echocardiography. Results: The left ventricular dimensions, fractional shortening, and left atrial diameter did not differ between the patients and the controls. Pd and Pmax were significantly higher in patients with scleroderma compared with controls: 51 ± 17 versus 28 ± 7 ms (p < 0.01) and 109 ± 10 versus 93 ± 6 ms (p < 0.01), respectively. There was a delay between the onset of the P wave on surface ECG and the onset of the late diastolic wave (A wave; PA) obtained by tissue Doppler echocardiography in patients with scleroderma compared with controls measured at lateral septal annulus (lateral PA; 122 ± 8 vs. 105 ± 7 ms, p = 0.001), septal mitral annulus (104 ± 11 vs. 93 ± 10 ms, p = 0.01) and tricuspid annulus (right ventricular PA; 71 ± 9 vs. 64 ± 7 ms, p = 0.05). Interatrial conduction time (lateral PA – right ventricular PA) was delayed in patients with scleroderma compared with controls (88 ± 13 vs. 76 ± 11 ms, p = 0.01). A positive correlation was detected between interatrial electromechanical delay (lateral PA – right ventricular PA) and Pd (r = 0.5, p = 0.03). Conclusion: Atrial conduction abnormalities as estimated with Pd and Pmax are significantly higher in patients with scleroderma compared with controls. There is a delay in both intraatrial and interatrial electromechanical coupling intervals in patients with scleroderma.

Objectives: Subclinical cardiac involvement may occur in patients with Behçets disease (BD). The purpose of our study was to assess the noninvasive parameters of biventricular function derived from Doppler tissue imaging (DTI) of the tricuspid and mitral annular motion in BD. Methods: Twenty‐one patients with BD and 20 control subjects were enrolled in this study. All subjects were selected to exclude those with cardiovascular risk factors. Standard echocardiography and pulsed DTI were obtained in every patient. Results: Peak systolic (13.71 ± 2.09 vs 20.01 ± 1.57, P < 0.001), peak early diastolic (11.26 ± 2.52 vs 15.35 ± 2.06, P < 0.001) tricuspid annular velocities were significantly lower in patients than controls. Peak systolic (8.68 ± 1.4 vs 12.25 ± 1.7, P < 0.001), peak early diastolic (7.89 ± 1.07 vs 9.94 ± 1.12, P < 0.001), and peak end diastolic (8.30 ± 1.32 vs 9.23 ± 0.91, P = 0.013) lateral mitral annular velocities were significantly lower in patients than controls. Conclusions: We demonstrated that myocardial velocities, were affected in patients with BD. Therefore, we conclude that right and left ventricular function is impaired in patients with BD.

Background: Idiopathic granulomatous mastitis (IGM) is a rare benign inflammatory disease of the breast. It is related to various etiological factors. The treatment of IGM is challenging as there is a lack of consensus in the literature and treatment options vary widely. Conservative treatment with antibiotics, glucocorticoids and immunosuppressive drugs, and surgery are used in the management of the disease. In this article we report our experience with IGM patients receiving immunosuppressive treatment. Patients and Methods: The medical records of patients with IGM receiving systemic therapy at the Hacettepe University Hospital between October 2007 and May 2010 were reviewed. 15 cases of histopathologically proven IGM were identified. The data was examined for risk factors and success of treatment. Results: 14 patients were given prednisolone together with azathioprine, and 1 patient who was pregnant at the time of diagnosis received only prednisolone (30 mg/day). 11 (73%) patients had a complete response to systemic therapy. 2 patients had a relapse, of whom 1 required surgical drainage and 1 was treated with a higher dose of glucocorticoids. Conclusion: Systemic therapy is a safe and effective treatment for IGM. The addition of azathioprine to glucocorticoid therapy permits quick tapering of the steroid doses and increases the treatment success.

BACKGROUND Familial Mediterranean fever (FMF) is characterized by sporadic, acute attacks of fever and serositis. Cardiovascular involvement is one of the leading cause of morbidity and mortality among FMF patients. Herein, we aimed to evaluate cardiac autonomic functions in FMF patients without overt cardiac symptoms. METHODS We enrolled 38 patients (20 female; mean age 34.4 ± 10.2 years) with FMF and 34 healthy subjects (18 female; mean age 33.2 ± 9.3 years). All participants underwent 24-hour Holter recording. Heart rate recovery (HRR) indices were calculated by subtracting first, second, and third minute heart rates from maximal heart rate. All patients underwent heart rate variability (HRV), heart rate turbulance (HRT) and QT dispersion analysis. The mean FMF duration was 9.8 ± 4.2 years. RESULTS Both groups were similar with regard to baseline characteristics. Mean HRR1 (p=0.001), HRR2 (p=0.003) and HRR3 (p<0.001) were significantly lower in FMF group. SDNN (standard deviation of all NN intervals), SDANN (SD of the 5 min mean RR intervals), RMSSD (root square of successive differences in RR interval), and PNN50 (proportion of differences in successive NN intervals >50 ms) and high-frequency (HF) components were significantly decreased, but low frequency (LF) and LF/HF were significantly higher in FMF patients. HRT onset and slope were significantly less negative in FMF patients. Also, QTd was significantly higher in FMF patients (p<0.001). CONCLUSION Patients with FMF showed delayed recovery of heart rate and abnormal HRV and HRT parameters with respect to normal subjects. Cardiac autonomic functions might be involved in FMF patients even in patients without cardiac symptoms.
