Epicardial adipose tissue thickness, flow-mediated dilatation of the brachial artery, and carotid intima-media thickness: Associations in rheumatoid arthritis patients.

AIM: The purpose of this work was to evaluate epicardial adipose tissue (EAT), carotid intima-media thickness (CIMT), and flow-mediated dilatation (FMD) of the brachial artery in rheumatoid arthritis (RA) patients using ultrasonographic methods. Interrelationships between these three parameters in RA patients were also investigated. METHODS: EAT thickness, CIMT, and FMD were measured by ultrasonography. We measured the disease activity score (DAS28), health assessment questionnaire (HAQ) score, and C-reactive protein (CRP) levels. Spearman or Pearson correlation analysis was used to evaluate the association between clinical findings, CIMT, FMD, and EAT. RESULTS: A total of 90 RA patients [19 men, mean age 54 years (range 21-76 years)] and 59 age- and gender-matched control subjects [17 men, mean age 54 years (range 26-80 years)] were included in the study. Patients with RA had a mean 4.34 DAS28 points (range 0-40 points) and the mean duration of the disease was 77.1 months (range 1-360 months). We found that RA patients had thicker EAT (7.7 ± 1.7 mm vs 6.2 ± 1.8 mm, p < 0.001), increased CIMT [0.9 (0.5-1.2) mm vs 0.6 (0.4-0.9) mm, p < 0.001], and decreased FMD values [5.7 % (- 23.5 to 20 %) vs. 8.5 % (- 4.7 to 22.2 %), p = 0.028] when compared to control subjects. CRP levels were significantly higher in the RA group [0.81 (range 0.1-13.5) vs 0.22 (range 0.05-12), p < 0.001]. EAT thickness was negatively correlated with FMD (r = - 0.26, p < 0.001) and positively correlated with CIMT values (r = 0.52, p < 0.001). CIMT also negatively correlated with FMD (r = - 0.29, p < 0.001). CONCLUSION: EAT can be simply measured by echocardiography and correlated with FMD and CIMT. It can be used as a first-line measurement for estimating burden of atherosclerosis in RA patients.

Mean platelet volume and platelet distribution width can be related to bone mineralization.

UNLABELLED: Platelets functions are related to bone resorption and formation. The present study aimed at studying the association between platelet function and bone mineralization. We showed that mean platelet volume (MPV) and platelet distribution width (PDW) levels in osteoporosis patients increased. The study also showed that PDW and age independently associated with bone mineralization. INTRODUCTION: MPV and PDW are widely used for assessing platelet function. Recently, authors argued that platelet function has an important role in bone mineralization. However, only one study has investigated the relationship between MPV and osteoporosis. We aimed to study the levels of MPV and PDW in postmenopausal osteoporosis. METHODS: We investigated 320 bone mineral density (BMD) measurements between the years 2012 and 2013 retrospectively in our clinic. Eighty patients whom chronic diseases are absent and all laboratory findings are complete enrolled in this study. Patients were divided in three groups as an osteoporosis, osteopenia, and normal BMD group. MPV and PDW levels were investigated in these groups. We performed correlation test and linear regression analysis to determine whether there is a relationship between platelet function markers and BMD measurements. RESULTS: Eighty patients were divided as an osteoporosis, osteopenia, and normal BMD group. MPV levels and PDW levels in the osteoporosis group were lower than the normal BMD group. PDW was positively correlated with femur total T (FTT) score and lumbar 1-4T (L1-4T) scores. Linear regression analysis showed that age and PDW were independently related to FTT and LTT scores. CONCLUSION: Platelet functions are related to the bone mineralization. PDW and MPV have a significant role in the development of postmenopausal osteoporosis.

Effect of hypertension on echocardiographic parameters in rheumatoid arthritis.

OBJECTIVE: Hypertension (HTN) is common in rheumatoid arthritis (RA) patients. Both HTN and RA have a negative impact on echocardiographically determined parameters including wall thickness, chamber diameter, diastolic function, epicardial adipose tissue (EAT) and carotid intima media thickness (CIMT). We aimed to demonstrate the effect of HTN on these parameters in RA patients. METHODS: Patients were divided into two groups: one group comprised 39 RA patients with HTN (7 male, mean age 56.3 ± 8.4 years) and the second comprised 38 age- and gender-matched RA patients without HTN (10 male, mean age 55.3 ± 7.4 years). We retrospectively analyzed the RA patients without overt structural heart disease by determining the study parameters from echocardiograph recordings. The two groups were compared in terms of echocardiographic parameters and disease characteristics. RESULTS: RA characteristics, chamber sizes and wall thicknesses did not differ between the groups. CIMT was significantly increased in the RA with HTN group (median 0.9 mm, range 0.6-1.2 mm vs. median 0.8 mm, range 0.6-1.0 mm; p = 0.031). EAT was also significantly increased in the RA with HTN group (8.2 ± 1.8 mm vs. 7.4 ± 1.4 mm; p = 0.022). Septal early diastolic E' wave velocities were significantly decreased in the RA with HTN group (8.8 ± 2.4 cm/s vs. 10.2 ± 1.8 cm/s; p = 0.016). CONCLUSION: HTN has a further negative impact on diastolic functions, CIMT and EAT in RA patients.

Evaluation of the temperament and character properties of patients with ankylosing spondylitis.

PURPOSE: The aim of this study was to evaluate temperament and character of ankylosing spondylitis (AS) patients and to examine the association between these specific temperament and character properties and clinical variables. PATIENTS AND METHODS: This study involved 73 AS patients. Temperament properties of patients were evaluated using Cloninger's Temperament and Character Inventory (TCI). Association between clinical variables and specific temperament features were evaluated using correlation and regression analyses. RESULTS: Forty eight (65.8 %) of the study participants were men and the mean age was 42 ± 11.4 years. There was slight negative correlations between self directedness (S) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores (p = 0.01, r = - 0.30), and between the Visual Analog Scale (VAS) and reward dependence (RD) scores (p = 0.03, r = - 0.26). Regression analysis showed that correlations between BASDAI and S, and between VAS and RD scores were statistically significant. CONCLUSION: Our study showed that the dimensions temperament and character are related to disease activation, and disease course is more severe in patients who have low scores in these TCI dimensions. Therefore, we suggest that evaluating temperament and character properties of AS patients will help clinicians to predict treatment compliance and motivation of patients during disease course.

H-FABP, cardiovascular risk factors, and functional status in asymptomatic spinal cord injury patients.

BACKGROUND: This was a cross-sectional study in the setting of a rehabilitation hospital. OBJECTIVE: The aim of the study was to determine the serum levels of heart-type fatty acid-binding protein (H-FABP) in patients with spinal cord injury (SCI). A further goal was to examine whether there is a relationship between H-FABP levels and Functional Ambulation Classification (FAC) scale, Functional Independence Measure (FIM) score, American Spinal Injury Association (ASIA) status, and metabolic syndrome (MetS). METHODS: The study included 56 SCI patients and 37 age- and sex-matched healthy control subjects who had not been diagnosed with coronary artery disease in the past. RESULTS: Serum H-FABP levels were significantly higher in patients with SCI than in control subjects: paraplegia group, 18.5 ± 11.4; tetraplegia group, 16.3 ± 9.1; control group, 6.7 ± 5.1 ng/ml (p < 0.001). There was no difference between the other cardiac enzymes (troponin I, AST, ALT, CK, CK-MB, and LDH) among the groups. The relationship between the serum H-FABP levels and FAC status was examined. There was a negative correlation between FAC status and H-FABP levels (p < 0.001, r = - 0.581). Patients with complete SCI were divided into two groups according to the level of the lesion: (lesion levels in C6-T6, n = 25; lesion levels in T7-L2, n = 11). In patients with complete motor injury, H-FABP levels were higher in subjects with injuries above T6 than in those with injuries below T6 (24.21 ± 10.1 and 14.1 ± 10.4, respectively; p = 0.011). Serum levels of H-FABP were higher in SCI patients with MetS (n = 10) than in those without MetS (n = 46; 25.8 ± 11.6 ng/ml vs. 16.42 ± 10.3 ng/ml, respectively; p = 0.014). Patients were then divided into two groups according to SCI duration: < 12 months (n = 27) and > 12 months (n = 29). H-FABP levels showed statistically significant differences between the two groups (14.8 ± 11.7 ng/dl and 20.9 ± 9.9 ng/dl, respectively; p = 0.036). CONCLUSION: H-FABP is related to MetS and FAC status in asymptomatic SCI patients.

Occupation in spinal cord injury patients in Turkey.

STUDY DESIGN: A cross-sectional survey. OBJECTIVES: To investigate the changes in the occupation of patients after spinal cord injury (SCI) and the factors that cause this change. SUBJECTS: The study involved 192 Turkish patients (41 female, 151 male) who had suffered SCI. The mean age of patients was 36.1+/-12.0 years. The mean follow-up time was 43.4+/-38.0 months. Before injury, 138 patients were employed in gainful occupations, 26 patients were housewives, 10 were retired, 7 were students and 11 patients were unemployed. Only 15 patients (7.8%) returned to their original occupations after injury. Thirteen patients (6.8%) are currently working in another job; 1 patient (0.5%) is a student; 10 (5.2%) are retired as was earlier; 40 (20.8%) are retired on grounds of disability; 26 (13.5%) are housewives; and 87 patients (45.3%) are currently unemployed. METHODS: Prospective data collection through a face-to-face interview on an established SCI Turkish sample. RESULTS: In our study, the rate of returning to work was found to be 14.6%. In the evaluation of factors affecting return to work after injury, educational level (P=0.00), pre-injury employment (P=0.01) and bladder-emptying method (P=0.03) were statistically significantly correlated with return to work. CONCLUSION: In this study, education, pre-injury employment and bladder-emptying method were found to be important factors in returning to work after SCI.
