Disability of Arm Shoulder and Hand Questionnaire in rheumatoid arthritis patients: relationship with disease activity, HAQ, SF-36.

Rheumatoid arthritis (RA) is a systemic disease that causes disability. Disability and quality of life indexes are used in the assessment and treatment of patients with RA. Disability of Arm, Shoulder and Hand Questionnaire (DASH) is a patient-based outcome measurement developed to evaluate the upper extremities. The aim of this study was to investigate the clinical relevance of DASH in RA patients and the relationship between disease activity and health-related quality of life measurements. One hundred and sixty-six RA patients were included in the study. Disease activity was measured with Disease Activity Score 28 (DAS28), Simplified Disease Activity Index (SDAI), and Clinical Disease Activity Index (CDAI). The DASH questionnaire, Short-Form 36 (SF-36), and Health Assessment Questionnaire (HAQ) were completed by all patients. The DASH score moderately correlated with DAS28 (r=0.672), SDAI (r=0.586) and CDAI (r=0.565). When the patients were grouped according to the activity obtained using the three disease activity measurements, DASH score was statistically significantly higher with higher disease activity (P<0.001). A high correlation (r=0.883) was found between DASH and HAQ (r=0.883). The SF-36 scores were correlated with DASH (r=-0.785 with physical component, r=-0.619 with mental component). DASH scores correlate with disease activity indices, functional disability and QoL and can be used in the assessment of upper extremities in patients with RA.

Comparison of the Bath Ankylosing Spondylitis Radiology Index and the modified Stoke Ankylosing Spondylitis Spine Score in Turkish patients with ankylosing spondylitis.

The objective of the present study was to compare two radiographic scoring methods (the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) and the Bath Ankylosing Spondylitis Radiology Index-spine (BASRI-spine)) in terms of reliability, construct validity, and feasibility in Turkish ankylosing spondylitis (AS) patients. The study involved seventy-four patients. The patients were evaluated with 100-mm visual analog scale (VAS) for pain, global assessment of patient, and global assessment of doctor. The laboratory evaluations of patients comprised erythrocyte sedimentation rate and serum C-reactive protein. Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), Bath AS Metrology Index (BASMI), and Bath AS Radiology Index (BASRI) were calculated. Bilateral cervical, lumbar spine, and anteroposterior pelvis radiographs of all patients were obtained and evaluated by two radiologists. Each radiograph was scored by two scoring methods, mSASSS and BASRI-spine, and these methods were tested according to the aspects of the Outcome Measures in Rheumatology Clinical Trials filter: reliability, construct validity, and feasibility. The BASRI-spine reached intra- and interobserver intraclass correlation coefficient (ICC) of 0.726 and 0.689, respectively. The mSASSS scores more reliable, with ICC of 0.831 and 0.840, respectively. The BASMI and BASFI correlated significantly with the two scoring systems, respectively (mSASSS r: 0.557, r: 0.319; BASRI-spine r: 0.605, r: 0.285). For the two methods, the magnitude of the correlation with disease duration was similar (mSASSS p < 0.01 and BASRI p < 0.01), but no significant correlation was observed when compared to the BASDAI. It is known that the BASRI-spine is a feasible method that reliably detects damage in patients with AS. However, the present authors believe that, in AS patients, mSASSS should be the radiological scoring method to choose because of less radiation exposure, along with excellent intra- and interobserver reliability.

Serum homocysteine level in patients with ankylosing spondylitis.

In this study serum homocystein (Hcy) level was measured and its relationship with disease activity criteria and treatment protocols was investigated in ankylosing spondylitis (AS) patients. Ninety-two AS patients and 58 healthy individuals were recruited. Erythrocyte sedimentation rate and serum C-reactive protein were determined. Bath AS disease activity index and Bath AS functional index were calculated. Serum Hcy levels >15 micromol/l were considered as hyperhomocysteinemia. The mean serum homocysteine levels were 14.40 and 12.60 micromol/l in patients with AS and the control group, respectively, and the difference between two groups was significant. While there was no significant difference between the sulfasalazine (SSZ) group with 14.25 micromol/l mean Hcy level and the methotrexate (MTX)/SSZ group with 16.05 micromol/l, there was a statistically significant difference between the Hcy levels of these two groups and Hcy level of 12.15 micromol/l of the non-steroidal anti-inflammatory drugs group, and 12.60 micromol/l Hcy level of the control group. Mean serum Hcy level was 13.65 micromol/l in patients with active AS and 14.60 micromol/l in patients with inactive AS, and there was no significant difference between the groups. In our study serum Hcy level was found to be significantly higher in patients with AS than in healthy control subjects. Especially for the AS patients receiving MTX and SSZ treatment without folic acid supplementation, addition of folic acid to their therapy may decrease the risk of cardiovascular disease which in turn decreases the mortality in these patients, but further prospective studies are needed for supporting these results.

Association of bone mineral density and vertebral deformity in patients with rheumatoid arthritis.

The aim of this study was to investigate the association of vertebral deformities developed as a result of osteoporosis in female patients with rheumatoid arthritis (RA) with bone mineral density (BMD) and disease activity parameters. In the study, 100 female patients with the diagnosis of RA and 56 healthy subjects were recruited. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and rheumatoid factor (RF) tests were performed and the number of swollen and tender joints, level of pain and health assessment questionnaire (HAQ) were recorded in order to evaluate disease activity. Anteroposterior and lateral thoracic and lumbosacral roentgenograms of all patients were taken for radiological examination and deformities of vertebrae were assessed. BMD measurements of patients were performed on vertebrae L1-4 of lumbar region and on total hip, femur neck, trochanter and Ward's triangle of the right side. Vertebral deformity was established in 30% of RA patient group and 7.1% of control group and this was statistically significant. In the statistical analysis, no statistically significant difference was found between BMD measurements of RA and control groups. Patients with RA were divided into two subgroups with regard to using corticosteroids (CS) or not. Vertebral deformity was 32.4% in the subgroup using CS and 24.1% in the subgroup not using CS, and the difference was not statistically significant. There was a correlation between number of deformed joint and age and vertebral deformity incidence. RA is a risk factor on its own for the development of osteoporosis and vertebral deformity and this risk increases by age, excess number of deformed joints and severe course of disease. We think that precautions should be taken immediately to suppress the disease activity as well as to protect the quality and density of bone and to prevent the development of vertebral deformity and fracture while planning the treatment of patients with RA.

The effect of outfitting style on bone mineral density.

AIM: Vitamin D deficiency is one of the most important risk factors in the development of osteoporosis. Recently, vitamin D deficiency is more frequently encountered than expected in Mediterranean countries, which are sunny most of the time. Our country is one of these sunny countries and here, we investigated the effect of outfitting style on bone mineral density (BMD) and plasma vitamin D levels in women aged between 30-40 years. METHOD: Eighty women, aged between 30 and 40 years, were included in the study. They were divided into two groups, depending on their dress selection. Group-1 consisted of 40 cases with an open clothing style, while the 40 women in group-2, preferred the covered clothing style. Women were questioned in terms of the risk factors for osteoporosis. Levels of plasma 25(OH)2 vitamin D3 and parathormone (PTH) were tested along with routine blood analyses. BMD of Lumbar 1-4, femur neck, trochanter, and Ward's triangle were measured. RESULTS: In group-2, number of pregnancies and body mass index (BMI) was statistically significantly higher (p < 0.05). When the laboratory parameters were compared, in group-2, only levels of plasma 25 (OH)2 vitamin D3 was significantly lower than group-1 (p < 0.05). There was no significant difference among groups in terms of BMD. In group-2, there was a positive correlation between BMI and BMD at L1-4, hip, femur neck, and trochanter regions (p < 0.01, 0.01, 0.05, and 0.05, respectively). CONCLUSION: Traditional clothing style leads to vitamin D deficiency in women. In order to meet vitamin D need, the face, arm and leg regions of the body should be exposed to one minimal erythemal dose (MED; i.e., slight redness of the skin) of sunlight, at least two or three times a week. We believe that these cases should be more closely monitored for bone loss, especially during postmenopausal period, which is considered as a risky term in terms of osteoporosis development.
