This study aimed to evaluate the prevalence of comorbidities in patients with rheumatoid arthritis (RA) compared with the non-RA population. The 2010–2012 Korea National Health and Nutrition Examination Survey (KNHANES), which assesses the general health status of populations in South Korea using interviews and basic health assessment, was analyzed retrospectively. Weighted prevalence and odds ratio (OR) of comorbidities were analyzed in patients with RA compared with the non-RA population. The overall weighted (n = 37,453,158) prevalence of RA was 1.5%. Patients with RA were older and more female predominant than subjects without RA. The prevalence of living in an urban area, college graduation, alcohol consumption and smoking was lower in patients with RA than non-RA. Patients with RA had more comorbidities including hypertension, dyslipidemia, myocardial infarction (MI) or angina, stoke, osteoarthritis, lung cancer, colon cancer, pulmonary tuberculosis, asthma, diabetes, depression, thyroid disease and chronic kidney disease. After adjusting socioeconomic and lifestyle characteristics, RA was associated with an increased prevalence of MI or angina (OR 1.86, 95% CI 1.17–2.96, p = 0.009), pulmonary TB (OR 1.95, 95% CI 1.24–3.09, p = 0.004), asthma (OR 1.97, 95% CI 1.05–3.71, p = 0.036), thyroid disease (OR 1.71, 95% CI 1.05–2.77), depression (OR 2.38, 95% CI 1.47–3.85, p < 0.001) and hepatitis B (OR 2.34, 95% CI 1.15–4.80, p = 0.020) compared with the non-RA population. Prevalence of solid cancer was not significantly associated with RA after adjustment. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the association between rheumatoid arthritis (RA) and hearing impairment in the Korean adult population. Audiometric and laboratory test data from the 2010–2012 Korean National Health and Nutrition Examination Survey (KNHANES) were used for analysis. The relationship between RA and hearing impairment was analyzed, adjusting for various known risk factors associated with hearing impairment. RA was defined in the questionnaire as “RA diagnosed by a physician (yes/no) through a standardized interview.” We defined hearing impairment according to 2 categories of frequency (low/mid and high) as follows (average values in kHz): low/mid frequency, 0.5, 1.0, and 2.0, and high frequency, 3.0, 4.0, and 6.0. Of the subjects, 15,158 (weighted n = 32,035,996) completed the audiometric tests. The overall weighted prevalence of RA was 1.5%. The prevalence of hearing impairment was higher in the subjects with RA than in those without RA, in both, the low/mid- and high-frequency categories (21.1% vs 7.5%, p < 0.001 and 43.3% vs. 26.2%, p < 0.001, respectively). In the multivariable logistic analysis, RA (odds ratios [OR] 1.47, 95% confidence interval [CI] 1.05–2.06, p = 0.025) was an independent risk factor of low/mid-frequency hearing impairment along with age (OR 1.12, 95% CI 1.12–1.13, p < 0.001), current smoking (OR 1.27, 95% CI 1.03–1.56, p = 0.026), and college graduation (OR 0.53, 95% CI 0.39–0.72, p < 0.001). In the multivariable analysis of high-frequency hearing impairment, RA did not show any association with hearing impairment. This study suggests that RA is associated with low/mid-frequency hearing impairment after adjustment for various known risk factors. Further study is needed to verify the hearing impairment in RA.

Objectives To evaluate the clinical courses and outcomes of patients with monoarthritis and to investigate the predictive factors of clinical outcomes. Methods A retrospective analysis was performed of 171 patients with chronic monoarthritis at a single tertiary hospital between January 2001 and January 2011. Baseline characteristics, radiographic findings and the clinical course were reviewed. Results The most commonly involved joints were the knees (24.0%), followed by the wrists (22.8%) and ankles (18.7%). A final diagnosis was established in 74 (43.3%) patients. Thirty-one (18.1%) patients were diagnosed with rheumatoid arthritis ( RA), 23 (13.5%) with peripheral spondyloarthritis (SpA), and 19 (11.1%) with Behçet's disease ( BD). Among 108 patients who were initially undiagnosed, 85 (78.7%) patients remained with undiagnosed monoarthritis, with relatively shorter symptom durations and requiring less treatment. The initially involved joint was a predictive factor for the final diagnosis: the wrist joint for RA (odds ratio [ OR] 11.58, P < 0.001), the ankle joint for SpA ( OR 6.19, P < 0.001), and the knee joint for BD ( OR 3.43, P = 0.014). Bony erosion at baseline was associated with progression to oligo- or polyarthritis ( OR 2.88, P = 0.030) and with radiographic progression. Conclusions In patients presenting with monoarthritis, a final diagnosis was established in less than half of the patients, and a majority of undiagnosed patients showed benign clinical courses. The initially involved joint and the presence of erosion at baseline were predictors of the final diagnosis and of clinical outcomes. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: To investigate the effects of benzo[a]pyrene (B[a]P), a major toxic component of cigarette smoke, on the expression of Slug and to determine the effect of B[a]P/Slug on the invasive properties of rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS). Method: The expression of Slug was measured by real-time PCR following the stimulation of FLS with different concentrations of B[a]P or EGF. The phosphorylation of the key enzymes in the signaling pathway was analyzed by western blots. Inhibitors of PI3K/Akt/mTOR pathway were used to confirm the critical pathway for Slug expression. An in vitro cell invasion assay was performed using RA FLS treated with Slug cDNA, Slug small interference RNA, or control. Results: Slug expression increased significantly following treatment with B[a]P or EGF in a dose-dependent manner. The stimulation of FLS with B[a]P or EGF induced the phosphorylation of Akt kinase, but not in ERK, JNK and p38. The Slug mRNA expression induced by B[a]P and EGF decreased significantly following the treatment with PI3K/Akt/mTOR inhibitors. Slug overexpression using Slug cDNA upregulated the invasive function of FLS, and Slug depletion using siRNA showed the opposite effect compared with the control. In addition, the stimulation with B[a]P increased the invasive function of the control siRNA-treated FLS but not in the Slug siRNA-treated FLS. Conclusion: Our data showed that B[a]P regulates the invasive properties of RA FLS through Slug expression. This mechanism may provide a novel molecular link underlying the association between smoking and increased radiographic progression in RA. [Copyright &y& Elsevier]

Aim To investigate the effects of Tubastatin A, a selective histone deacetylase-6 inhibitor, on synovial inflammation and joint destruction in a collagen antibody-induced arthritis ( CAIA) mouse model. Methods Collagen antibody-induced arthritis mice were given daily intraperitoneal injections of various concentrations of Tubastatin A (0, 10, 50, 100 mg/kg). The clinical score and paw thickness were measured. Mice were sacrificed on day 15, and the expression of tumor necrosis factor ( TNF)-α, interleukin ( IL)-1 and IL-6 in the serum were analyzed using enyme-linked immunosorbent assay ( ELISA). Two pathologists independently measured the synovitis score. Micro-computed tomography ( CT) scans of the joints were performed to quantify joint destruction. The expression of IL-6 from human fibroblast-like synoviocytes ( FLSs) after incubation with various doses of Tubastatin A (0, 0.75, 1.5, 3 μmol/L) was measured using ELISA. Results The clinical arthritis score was significantly attenuated and paw thickness was lower in the group treated with 100 mg/kg Tubastatin A compared with those treated with vehicle alone. The synovitis score was significantly reduced in the 100 mg/kg Tubastatin A-treated group compared with the control group. Micro- CT showed that quantitative measures of joint destruction were significantly attenuated in the 100 mg/kg Tubastatin A-treated group compared with the control. The expression of IL-6 in the sera was lower in the mice treated with Tubastatin A compared with the control. The expression of IL-6 in human FLSs decreased dose-dependently after incubation with Tubastatin A without affecting cell viability. Conclusions Tubastatin A successfully ameliorated synovial inflammation and protected against joint destruction in CAIA mice, at least in part, by modulating IL-6 expression. [ABSTRACT FROM AUTHOR]
