The WHODAS II is a valid and reliable measure of HRQOL in cross-sectional studies of patients with early inflammatory arthritis. Research is still required to investigate potential item redundancy and determine its usefulness in longitudinal studies.
Despite observed beneficial effects of short-term supplementation of L-carnitine in decreasing serum inflammatory mediators and improving pain in knee OA patients, further studies are needed to achieve concise conclusions.
Genetic factors that predispose individuals to Behcet's disease (BD) are considered to play an important role in the development of the disease. The serum level of tumor necrosis factor (TNF) is elevated in patients with BD, and a dramatic response to anti-TNF-alpha antibody treatment further supports the role of TNF in BD. We investigated the distribution of TNF-alpha promoter -1031T/C and -308G/A polymorphisms in 53 BD patients of Iranian Azeri Turks and 79 matched healthy controls, via the PCR-RFLP technique. The frequency of the TNF-alpha -1031C allele was significantly higher in Behcet's patients than in healthy controls (p < 0.0001, OR = 3.08; 95% CI = 1.73-5.47), whereas the frequency of the TNF-alpha -308A allele was similar in the two compared groups. The frequency of CG haplotype was significantly higher (p < 0.0001, OR = 3.42; 95% CI = 1.89-6.18), and that of the TA haplotype was significantly lower in BD patients than in healthy controls. These results suggest that TNF-alpha is a susceptibility gene for BD in patients from Iranian Azeri Turk ethnic group.
Background:Ankylosing spondylitis (AS) is a chronic destructive and inflammatory disease of the axial skeleton manifested by back pain and progressive stiffness of the spine.Objectives:The aim of the present cross-sectional study was to evaluate and identify factors leading to delayed diagnosis of AS in Iranian patients.Patients and Methods:Sixty patients, (53 males, 7 females) with a diagnosis of AS according to the modified New York criteria were recruited. Diagnosis delay was defined as the interval between a patient’s first spondyloarthritic symptoms [inflammatory back pain (IBP), inflammatory arthritis, enthesopathy and uveitis] and a correct diagnosis of AS.Results:The average age of patients at diagnosis of AS was 36.4 ± 4.5 years and the average of delay in diagnosis was 6.2 ± 3.5 years. The most common diagnosis at the first visit was disc herniation (68.3%). Delay in diagnosis of Human Leukocyte Antigen (HLA-B27) positive and negative patients were 4.6 ± 2.2 years and 10.1 ± 3.2 years, respectively (P = 0.0001). Diagnosis delay in patients with morning stiffness and IBP were significantly shorter than that of patients without these symptoms (P = 0.0001 and P = 0.001, respectively). Patients with uveitis had the shortest diagnosis delay (P = 0.02). The Bath Ankylosing spondylitis disease activity index (BASDAI) was not significantly different in early (< 3years) and late (> 3years) diagnosis (3.3 ± 0.9 and 3.6 ± 0.7, respectively) (P = 0.18), but the Both ankylosing spondylitis functional index (BASFI) was significantly different between them (3.3 ± 1.0 and 4.1 ± 0.7 respectively) (P = 0.001).Conclusions:In this study, delay in diagnosis was similar to other studies. Educating physicians to careful history taking especially in the case of IBP, non-musculoskeletal symptoms such as uveitis and precise physical examination are important in early diagnosis.
Intake of energy and some micronutrients were significantly lower than the recommended values. However, no relationship was found between intake of different food groups or nutrients with disease activity or serum antioxidant capacity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
