Peer-led education or booklet for knowledge transfer about disease: A randomized-controlled trial with ankylosing spondylitis patients.

Objectives: This study aims to investigate whether peer-led group education + booklet is superior to booklet only to increase ankylosing spondylitis (AS) patients' knowledge about their disease. Patients and methods: A total of 56 patients (46 males, 10 females; mean age 41.9±9.2 years; range, 22 to 58 years) with a definite diagnosis of AS who were under follow-up in our outpatient clinic between August 2010 and January 2012 were included in this study. The patients were randomly allocated to the peer-led education + booklet (education group, n=27) and booklet only (control group, n=29). To assess the level of patients' knowledge, a patient knowledge questionnaire containing four domains was used. Evaluations were made at baseline, four weeks, and six months. The variables were "number of correct choices" (NoCC), "number of correct items" (NoCI) and percent of correct choices for each domain; the later one was resembled by the name of that domain (area A, area B, etc.). Results: The variables that improved in both groups were NoCC, NoCI, and "pharmacotherapy and physical therapy area" (area C). These improvements were similar between the groups (respectively, p=0.915, p=0.830, p=0.791). Conclusion: Reading a booklet alone is as successful as peer-led education + booklet for knowledge transfer about their disease in patients with AS. In this study, the most knowledge gain was achieved in "drug treatment and physical therapy" area.

Assessment of subclinical atherosclerotic cardiovascular disease in patients with ankylosing spondylitis.

OBJECTIVE: The aim of the present study was to compare patients with ankylosing spondylitis (AS) with healthy controls with respect to subclinical atherosclerotic cardiovascular disease (CVD). METHODS: A total of 44 patients with AS with no history of CVD, diabetes mellitus, hypertension, chronic kidney disease, and lipid-lowering drug use were compared with 40 age- and sex-matched healthy controls with respect to carotid intima-media thickness (CIMT) and pulse wave velocity (PWV), which are surrogate markers of subclinical atherosclerosis. Correlation analysis was also performed to examine the association between surrogate markers and disease activity with inflammation [Ankylosing spondylitis disease activity score with C-reactive protein (ASDAS-CRP)]. RESULTS: In addition to age and sex, both groups were comparable with respect to cigarette smoking, body mass index, and high-density lipoprotein cholesterol (p=0.425, p=0.325, and p=0.103, respectively). The level of total cholesterol was significantly lower in patients with AS (p=0.002). Nonsteroidal anti-inflammatory drug and tumor necrosis factor alpha inhibitor use ratios in patients with AS were 79.5% and 65.9%, respectively. There was no significant difference between both groups regarding PWV and CIMT (p=0.788 and p=0.253, respectively). In patients with AS, there was a significant correlation between ASDAS-CRP and CIMT (r=0.315, p=0.038), but the correlation between ASDAS-CRP and PWV was not significant (r=-0.183, p=0.234). CONCLUSION: The results of the present study could not provide sufficient evidence whether disease activity with inflammation caused subclinical atherosclerotic CVD in patients with AS without overt CVD. The increased atherosclerotic CVD risk is most probably multifactorial in patients with AS, but the extent of the contribution of disease activity with inflammation to increased atherosclerosis is controversial.

Are We Able to Suppress Disease Activity Adequately in Patients With Established Rheumatoid Arthritis? An Observational and Cross-Sectional Study.

OBJECTIVES: This study aims to explore current disease activity status and simultaneous pharmacological therapies in patients with established rheumatoid arthritis (RA) to determine the extent to which treatment targets are achieved. PATIENTS AND METHODS: One hundred patients (7 males, 93 females; median age 57 years; range 31 to 76 years) with established RA receiving any conventional synthetic disease modifying anti-rheumatic drug (DMARD) and/or biological DMARD for at least three months were enrolled. Disease activity was determined by using the Simplified Disease Activity Index. First, patients were categorized into four groups as remission, low disease activity, moderate disease activity, and high disease activity. Then, they were divided into two subgroups, namely a remission/low disease activity subgroup and moderate disease activity/high disease activity subgroup. RESULTS: Fifty-one percent of the patients had remission or low disease activity. The most frequently used conventional synthetic DMARDs were methotrexate (50%) and leflunomide (34%). Forty-five percent of patients were receiving glucocorticoid therapy. In patients receiving only conventional synthetic DMARDs, the proportion of remission and low disease activity was 54% (42/78). Forty-two percent (8/19) of the patients receiving biological DMARDs were in remission or had low disease activity. A comparison of subgroups revealed that median age and sulfasalazine use were significantly higher in the moderate disease activity/high disease activity subgroup. CONCLUSION: The results of this study demonstrated that half of patients with established RA had moderate or high disease activity in our local outpatient clinic. Some barriers might be responsible for the difficulties in controlling disease activity. Determining such barriers might result in a better clinical response during the management of patients with established RA in real-life practice.

Description of the registry of patients with ankylosing spondylitis in Turkey: TRASD-IP.

A web-based application patient follow-up program was developed to create a registry of patients with ankylosing spondylitis (AS) by the Turkiye Romatizma Arastirma Savas Dernegi (TRASD) AS Study Group. This study describes the methodological background and patient characteristics. The patient follow-up program is a web-based questionnaire, which contains sections on socio-demographic data, anamnesis, personal and family history, systemic and musculoskeletal examination, laboratory and imaging data and treatment. Between October 1, 2007 and February 28, 2009, 1,381 patients from 41 centers were included in the registry (1,038 males [75.2%]; mean age 39.5 ± 10.7 years). Mean disease duration was 12.1 ± 8.5 years, and mean time from initial symptom to diagnosis was 5 ± 6.8 years (median 2 years). HLA-B27 positivity was detected in 73.7% of 262 patients tested. Manifestations of extraarticular involvement were anterior uveitis (13.2%), psoriasis and other skin and mucous membrane lesions (6%) and inflammatory bowel disease (3.8%). The prevalence of peripheral arthritis was 11.2%. In 51.7% of patients, the Bath AS Disease Activity Index was ≥4. But since our patients consisted of the ones with more severe disease who referred to the tertiary centers and needed a regular follow-up, they may not represent the general AS population. Disease-modifying anti-rheumatic drugs were being used by 41.9% of patients, with 16.4% using anti-TNF agents. TRASD-IP (Izlem Programi: Follow-up program) is the first AS registry in Turkey. Such databases are very useful and provide a basis for data collection from large numbers of subjects. TRASD-IP gives information on the clinical and demographic profiles of patients, and the efficacy and safety of anti-TNF drugs, examines the impact on quality of life, and provides real-life data that may be used in cost-effectiveness analyses.

Determinants of quality of life (QoL) in elderly stroke patients: a short-term follow-up study.

The aim of this study was to determine the quality of life (QoL) at the third month after stroke and to identify the factors related with and determinants of QoL in geriatric stroke patients. Eighty of 122 patients who were assessed within the first week after stroke were reevaluated at the third month. Patients were divided into two groups as those of ≥65 years old (geriatric group) and those of <65 years old (non-geriatric group). The stroke severity, functional status, and ambulation level were assessed by the Canadian neurological scale (CNS), the functional independence measure (FIM), and the functional ambulation classification scale (FACS) within the first week of stroke, respectively. Depression and QoL levels were also determined at the third month using the Zung self-rating depression scale (ZDS) and both the Short Form-36 (SF-36) survey and the stroke-specific quality of life (SSQoL) scale, respectively. The QoL of 80 patients according to the SF-36 were lower than those of general population. No significant difference was found in stroke severity, functional status at baseline and third month, depression and QoL between geriatric and non-geriatric patients (p>0.05). The most influenced subscale of QoL was work/productivity in geriatric patients, and the main determinant of QoL was the functional status during the assessment. Stroke patients had an impaired QoL, and geriatric patients did not demonstrate a difference in terms of QoL compared to non-geriatric patients. The fact that the main determinant of QoL was functional status has been suggested that improving of physical function may be helpful to provide a better QoL for stroke patients.

Inter-rater reliability of the Modified Ashworth Scale and modified Modified Ashworth Scale in assessing poststroke elbow flexor spasticity.

The Modified Ashworth Scale (MAS) is commonly used in clinical practice for grading spasticity. However, it was modified recently by omitting grade '1+' of the MAS and redefining grade '2'. The aim of this study was to investigate the inter-rater reliability of MAS and modified MAS (MMAS) for the assessment of poststroke elbow flexor spasticity. Sixty-four patients with poststroke hemiplegia were enrolled. The mean age and time since the stroke were 60.5 ± 11.9 years and 15.7 ± 10.2 weeks, respectively. The patients were tested by two raters having equal experience in applying MAS. They were not subjected to any training for administering MMAS. After performing no more than two test movements, the raters graded the resistance felt, according to the MAS and MMAS, respectively based on same stretch. The degree of agreement was analyzed using the weighted kappa (kw) statistic. Inter-rater agreements were very good for both MAS and MMAS, with weighted kappa values of 0.868 and 0.892, respectively. The highest agreements were observed for grade '0' in applying MAS and for grade '2' in applying MMAS; on the other hand, the lowest agreements were observed for grade '2' in applying MAS and for grade '3' in applying MMAS. According to our results, MAS and MMAS have very good inter-rater reliability for assessment of poststroke elbow flexor spasticity. Neither of the scales is superior to each other when using them to grade spasticity in patients with hemiplegia for this muscle group.

Validation of the Turkish version of the foot and ankle outcome score.

The objective is to develop a Turkish version of the foot and ankle outcome score (FAOS) and to investigate its validity and reliability. The Turkish version of FAOS was developed after the translation and back-translation. The translated version was pretested on 20 patients with rheumatoid arthritis. Then, the Turkish FAOS was administered to 55 patients having foot and ankle problems. They were also evaluated by using the four subscales of the Turkish version of AIMS2, and the Turkish version of SF-36 questionnaire to test validity. Fifty patients filled out the FAOS for second time to determine test­retest reliability. Construct validity was investigated with use of Spearman's rank correlation coefficient. Test­retest reliability was assessed with use of the intraclass correlation coefficient (ICC) and Cronbach's alpha score. The psychometric properties of the Turkish FAOS were generally similar to the original FAOS. The random ICC for the five subscales ranged from 0.70 to 0.96. The Cronbach's alpha coefficient ranged from 0.79 to 0.97. Construct validity of the FAOS was good. The Turkish FAOS correlated with the SF-36 and AIMS2 scales. The Turkish version of FAOS was valid and reliable instrument to assess the foot and ankle related problems. However, to assess its responsiveness further studies are needed.

The validity and reliability of the Turkish version of the Rheumatoid and Arthritis Outcome Score (RAOS) in patients with rheumatoid arthritis.

The goal of our study was to develop a Turkish version of the Rheumatoid and Arthritis Outcome Score (RAOS) in patients with rheumatoid arthritis (RA) and to assess its reliability, validity, and sensitivity to change. The Turkish version of RAOS was developed according to cross-cultural guidelines by using the "translation-back translation" method. Fifty-eight patients with RA were assessed with it. To assess its validity, patients were also evaluated with Turkish versions of the Health Assessment Questionnaire, five subscales of Arthritis Impact Measurement Scales, and the Rheumatoid Arthritis Quality of Life questionnaire. Test-retest reliability of the RAOS questionnaire was calculated on 58 patients within 1 week. Construct validity was investigated with use of Spearman's rank correlation coefficient. Test-retest reliability was assessed with use of the intraclass correlation coefficient (ICC) and Cronbach's alpha score. Sensitivity to change after the 4-week home-based exercise program was evaluated with paired t test comparisons. The Turkish version of the RAOS met set criteria of reliability and validity. The random ICC for the five subscales ranged from 0.76 to 0.94. Interitem correlation measured by Cronbach's alpha ranged from 0.81 to 0.94. Correlations were found between RAOS subscales and all of the evaluation parameters (p < 0.01). RAOS subscales showed significant improvements after the 4-week home exercise program except for the symptom and quality of life subscales (p < 0.05). The effect sizes were ranged from 0.20 to 0.37 and were considered small. The results of this study showed that the Turkish version of RAOS was reliable, valid, and responsive in patients with rheumatoid arthritis.

Comorbidity in patients after stroke: impact on functional outcome.

OBJECTIVE: To evaluate the incidence of comorbid diseases and their impact on functional outcome in patients after stroke. DESIGN: A prospective study. SUBJECTS: A total of 140 patients after stroke. METHODS: Comorbidities were assessed with the Liu comorbidity index. Functional independence was evaluated using the Functional Independence Measure (FIM). The relationship between comorbidities and functional outcomes were investigated. The impact of comorbidities on functional outcome was examined with multiple stepwise regression analysis. RESULTS: Ninety-four (67%) of 140 patients completed the study. The most frequent comorbid condition was hypertension at the initial visit. The weighted comorbidity index at baseline was negatively correlated with the follow-up FIM score and functional gain. Multiple regression analysis revealed that follow-up FIM score could be best explained by FIM at admission and the contribution of the weighted comorbidity index to functional outcome was 3.1%. CONCLUSION: Comorbid diseases are common among patients after stroke. They were shown to have a negative correlation with functional outcome; however, their impact on functional outcome was not clear. The proper evaluation of comorbid conditions should be included in stroke outcome research.

A Turkish version of the Bath Ankylosing Spondylitis Disease Activity Index: reliability and validity.

The aim of this study was to develop a Turkish version of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and assess its reliability, validity, and sensitivity to change. The Turkish version was obtained after a translation and back-translation process. Seventy-one patients with ankylosing spondylitis were assessed with it. To assess its validity, patients were also evaluated with the Turkish version of the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath Ankylosing Spondylitis Metrology Index (BASMI), the Bath Ankylosing Spondylitis Patient Global Score (BAS-G), and physicians' assessments of disease activity. Over 24 h, the Turkish BASDAI did not show significant differences between the two assessments (P>0.05). Correlations were found between BASDAI and all of the evaluation parameters except BASMI (P<0.01). Both BASDAI and BASMI showed significant improvements after 8-week home exercise programmes. The results of this study show that the Turkish version of the BASDAI is reliable, valid, and sensitive to change.

The Turkish versions of the Bath Ankylosing Spondylitis and Dougados Functional Indices: reliability and validity.

OBJECTIVE: The aim of this study was to develop a Turkish version of the Bath Ankylosing Spondylitis Functional Index (BASFI) and Dougados Functional Index (DFI) and assess their reliability, validity, and sensitivity to change. METHODS: The Turkish versions of the BASFI and DFI were obtained after a translation and back-translation process. Seventy-one patients with ankylosing spondylitis (AS) were included in the study. For investigation of the reliability of the BASFI and DFI, 36 of the patients recompleted both indices on the following day. To assess validity, the patients were evaluated with the Bath AS Disease Activity Index (BASDAI), Bath AS Metrology Index (BASMI), Bath AS Patient Global Score (BAS-G), physicians' assessment of disease activity, Bath AS Radiology Index-spine (BASRI-s) and sacroiliac joints, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). To assess the sensitivity to change, 16 patients were included in an 8-week home exercise program. In addition, 16 who had been on nonsteroidal anti-inflammatory drug (NSAID) treatment were requested to stop the treatment for 1 to 2 weeks. RESULTS: There were no significant differences in BASFI and DFI scores on two occasions within 24 h (P>0.05). The results showed correlations between both of the functional indices and the aforementioned validation parameters except ESR, CRP, and radiologic changes in the sacroiliac joints. The BASFI and DFI scores and BASMI and BASDAI values showed significant improvements in the home-exercise group. For the group of patients whose NSAIDs were stopped, BASFI, DFI, and BASDAI scores showed significant increase, whereas the mean BASMI score did not change. CONCLUSION: The results indicate that the Turkish versions of the BASFI and DFI are reliable, valid, and sensitive to change.
