RESUMO
The Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire is a disease-specific measure of needs-based quality of life developed in the UK and the Netherlands. This study describes translation, validation, and reliability of the scale into Turkish population. The ASQoL was translated into Turkish using the dual-panel process. Content validity was assessed via cognitive debriefing interviews with ankylosing spondylitis (AS) patients. Patients with AS according to modified New York criteria were recruited into the study from 12 hospitals of all part of Turkey. Psychometric and scaling properties were assessed via a two administration survey involving the ASQoL, the Nottingham Health Profile (NHP), Bath AS Functional Index (BASFI), and Bath AS Disease Activity Index (BASDAI). Classical psychometrics assessed reliability, convergent validity (correlation of ASQoL with NHP, BASFI, and BASDAI) and discriminative validity (correlation of ASQoL with perceived AS-severity and general health). Cognitive debriefing showed the new Turkish ASQoL to be clear, relevant, and comprehensive. Completed survey questionnaires were received from 277 AS patients (80% Male, mean age 42.2/SD 11.6, mean AS duration 9.4 years/SD 9.4). Test-retest reliability was excellent (0.96), indicating low random measurement error for the scale. Correlations of ASQoL with NHP sections were low to moderate (NHP Sleep 0.34; NHP Emotional Reactions 0.83) suggesting the measures assess related but distinct constructs. The measure was able to discriminate between patients based on their perceived disease severity (p < 0.0001) and self-reported general health (p < 0.0001). The Turkish version of ASQoL has good reliability and validity properties. It is practical and useful scale to assess the quality of life in AS patients in Turkish population.

OBJECTIVE: To assess the usefulness of Duruöz's Hand Index (DHI) in patients undergoing haemodialysis. METHODS: Patients receiving haemodialysis for more than 2 months were recruited randomly. Demographic, clinical and functional characteristics of patients were evaluated. Functional assessment was performed with DHI, Hand Functional Index (HFI), Health Assessment Questionnaire (HAQ), Purdue Pegboard, grip strength and 3 kinds of pinch strengths. DHI was correlated (Spearman's) with the other functional parameters in assessing the convergent validity and with non-functional parameters in assessing the divergent validity. RESULTS: Sixty patients with a mean age of 50.05 were recruited. The average duration of haemodialysis was 55.02 months. DHI is significantly correlated with HAQ, HFI, Purdue Pegboard scores, grip strength and 3 types of pinch strengths while no significant correlation was found with non-functional parameters. CONCLUSIONS: DHI is a practical scale which is efficient in assessing accurately the functional disability of the hand in patients receiving haemodialysis.

Involvement of the costovertebral (CV) and costotransverse (CT) as well as the sacroiliac (SI) joints is known to occur in patients with ankylosing spondylitis (AS). The functional significance of these changes is not clear. We have performed clinical and radiological evaluations and assessed the effect of joint involvement on pulmonary function. We detected radiologic evidence of involvement of the CV joint in 80% of patients and of the CT joint in 60 %. We found a direct relation between the severity of CV, CT and SI joint affliction, and the severity of CV and SI joints were related to time of evolution of the disease. Pulmonary function tests revealed neither restrictive nor obstructive defects. No relation was found between pulmonary function and CV and CT joint affliction. Patients with stiffer spines had a tendency to have pulmonary function tests within the lower limit of the normal range. In patients with AS diaphragmatic breathing might compensate the chest respiration to some extent.

Rheumatoid arthritis (RA) is a heterogeneous disorder with a spectrum of clinical severity ranging from mild arthritis to a crippling joint disease with involvement of internal organs. Carnitine is essential for muscle energy production and is required for the transport of long chain fatty acids and the acyl coenzyme A derivatives across the inner mitochondrial membrane. The levels of malondialdehyde (MDA), an index of lipid peroxidation, and the antioxidants copper-zinc superoxide dismutase (CuZnSOD), glutathione (GSH), ceruloplasmin (CP), catalase (CAT), and carnitine were assessed in 42 patients with RA and 24 control subjects. While plasma carnitine and erythrocyte CuZnSOD levels were significantly lower in the patients with RA compared with the control group (p<0.01 and p<0.001, respectively), the CAT level was not different from controls (p>0.05). Plasma MDA, CP, and erythrocyte GSH levels were significantly higher than in the control group (p<0.001, p<0.001 and p<0.01, respectively). MDA levels showed a positive correlation with CP and GSH levels (r=0.716, p<0.001 and r=0.492, p<0.01, respectively). However, MDA, GSH, and CP demonstrated a negative correlation with carnitine (r=-0.719, p<0.001; r=-0.559, p<0.01, and r=-0.635, p<0.001, respectively) in the patient group but not in controls. There was also a significant positive correlation between CP and GSH levels (r=0.561, p<0.01). However, neither CuZnSOD nor CAT levels demonstrated correlation withcarnitine, MDA, GSH, or CP levels. It was interesting that CAT activity was not altered and CuZnSOD activity decreased when compared with the control group. These results suggest that while CP, MDA and GSH levels increased, carnitine and CuZnSOD levels decreased, but CAT activity was unchanged.

OBJECTIVE: This study investigated whether any genomic change occurs in DNA level in ankylosing spondylitis (AS) by measuring sister chromatid exchange (SCE) frequency. METHODS: SCE frequency was detected on metaphase chromosomes obtained from peripheral blood lymphocyte cultures in 15 patients diagnosed as having AS. SCE values were also obtained from 15 healthy subjects as a control group. SCE frequencies were detected from metaphases obtained from standard blood cultures by using bromodeoxyuridine and staining by Giemsa. RESULTS: SCE frequencies of AS were statistically higher than those of the control group (p < 0.005). CONCLUSION: These results suggest that genetic factors may play a more important part than realised in the aetiology of AS.
