Abstract

To investigate the reliability and validity of the Turkish version of the Dougados functional index (DFI) in patients with ankylosing spondylitis (AS). The Turkish version of DFI was obtained after a translation and back-translation process. Seventy consecutive patients with AS were enrolled. Patients were requested to complete the questionnaire on the day of admission (first visit), a second time within 24 h after admission (second visit), and on a third occasion. Reliability, validity and reproducibility of the Turkish version of the index were assessed. All the items showed significant correlations with the total index score with r-values ranging from 0.516 to 0.817. Cronbach α score was calculated as 0.908. Significant correlations were found between the total DFI score and Schober test ( r=−0.293, P<0.05), occiput-wall distance ( r=0.384; P<0.01) finger-to-floor distance ( r=0.450, P<0.001), chest expansion ( r=−0.331, P<0.01) and Dougados articular index ( r=0.352, P<0.05). Good correlations were found between individual DFI items and the total score ( r=between 0.533 and 0.882, p< 0.001) for the first and second visits, showing good reproducibility of the index. Conclusion: the Turkish version of DFI has good reliability, validity and reproducibility, confirming its utility for trials in Turkish AS patients. [ABSTRACT FROM AUTHOR]

Abstract

Purpose: Increased chromosomal breakage and rearrangements have been reported in cell cultures of blood, skin and aponeurosis in patients with systemic sclerosis (SS). Among the drugs used for SS, d-penicillamine have been shown to increase sister chromatid exchange (SCE) in vitro, whereas there exist no data available to our knowledge for colchicine. Method: SCE frequencies were searched in 27 non-smoking patients with SS (mean age ± SD; 46.0 ± 11.9; 3 males, 24 females) of whom 8 on only colchicine and 10 on only d-penicillamine. In nine patients SCE was also studied after 45 days of colchicines administration as well. Twenty-one non-smoking healthy individuals (mean age ± SD; 34.8 ± 8.2; 4 males, 17 females) were taken as the control group. Results: When patients on d-penicillamine were excluded, SCE values were comparable among the patients with colchicine users (6.24 ± 0.45, n = 8) and non-users (6.22 ± 0.26, n = 8). Similarly when colchicine users were excluded no significant difference was found in SCE values between patients on d-penicillamine (6.08 ± 0.24, n = 10) and patients that were not taking the drug (6.22 ± 0.26, n = 8). Initial SCE values and those after 45 days of colchicine commencement were comparable (n = 9; 6.17 ± 0.24 and 6.30 ± 0.39, respectively). Conclusion: Colchicine and d-penicillamine usage appears not to effect SCE rates in the studied patients with systemic sclerosis. [ABSTRACT FROM AUTHOR]

Abstract

Reactive arthritis (ReA) is defined as a joint inflammation triggered by a distant infection, with no cultivable microbes in the joints. Although efforts have been made to characterize the microorganism linked to ReA, no definite common feature has so far emerged. Here we present a case of ReA which occurred after a zoophilic (canine genus) sexual intercourse. [ABSTRACT FROM AUTHOR]

Abstract

Takayasu arteritis is a rare inflammatory disease of large arteries. We performed a genetic study in Takayasu arteritis comprising 6,670 individuals (1,226 affected individuals) from five different populations. We discovered HLA risk factors and four non-HLA susceptibility loci in VPS8, SVEP1, CFL2, and chr13q21 and reinforced IL12B, PTK2B, and chr21q22 as robust susceptibility loci shared across ancestries. Functional analysis proposed plausible underlying disease mechanisms and pinpointed ETS2 as a potential causal gene for chr21q22 association. We also identified >60 candidate loci with suggestive association (p < 5 x 10(-s)) and devised a genetic risk score for Takayasu arteritis. Takayasu arteritis was compared to hundreds of other traits, revealing the closest genetic relatedness to inflammatory bowel disease. Epigenetic patterns within risk loci suggest roles for monocytes and B cells in Takayasu arteritis. This work enhances understanding of the genetic basis and pathophysiology of Takayasu arteritis and provides clues for potential new therapeutic targets., National Institute of Arthritis and Musculoskeletal and Skin Diseases of the National Institutes of HealthUnited States Department of Health & Human ServicesNational Institutes of Health (NIH) - USANIH National Institute of Arthritis & Musculoskeletal & Skin Diseases (NIAMS) [R01 AR070148]; National Institute of Arthritis and Musculoskeletal and Skin DiseasesUnited States Department of Health & Human ServicesNational Institutes of Health (NIH) - USANIH National Institute of Arthritis & Musculoskeletal & Skin Diseases (NIAMS) [U54 AR057319, U01 AR51874 04]; National Center for Research ResourcesUnited States Department of Health & Human ServicesNational Institutes of Health (NIH) - USANIH National Center for Research Resources (NCRR) [U54 RR019497]; Office of Rare Diseases Research of the National Center for Advancing Translational Sciences; Imperial College, National Institute for Health Research, Biomedical Research Centre; Wellcome TrustWellcome TrustEuropean Commission [WT107881]; Medical Research CouncilUK Research & Innovation (UKRI)Medical Research Council UK (MRC)European Commission [MC_UU_00002/4], This work was supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases of the National Institutes of Health grant R01 AR070148 to A.H.S.
