ABSTRACT

PURPOSE: To investigate associations between serum thyroid stimulating hormone (TSH) receptor antibody (TRAb) levels and Graves' orbitopathy (GO) activity/severity in chronic-stage GO and compare the performance of two newly-developed TRAb assays (third-generation TSH-binding inhibition immunoglobulin [TBII] assay versus Mc4 thyroid-stimulating immunoglobulin [TSI] bioassay). METHODS: This study is a retrospective review of medical charts and blood tests from Korean GO patients who first visited the departments of ophthalmology and endocrinology, Yonsei University College of Medicine from January 2008 to December 2011, were diagnosed with GO and Graves' hyperthyroidism, and were followed up for > or =18 months. Third-generation M22-TBII and Mc4-TSI assays were performed in the chronic-inactive GO patients in whom euthyroidism status was restored. Patients' GO activity/severity clinical activity scores (CAS), and modified NOSPECS scores were examined for a correlation with TRAb assays. RESULTS: Fifty patients (mean age, 41.3 years; 41 females) were analyzed. The mean duration of Graves' hyperthyroidism symptom was 63 months (range, 18 to 401 months) and that of GO was 46 months (range, 18 to 240 months). All patients had been treated previously with anti-thyroid drugs for a median period of 52.3 months, and two patients underwent either radioiodine therapy or total thyroidectomy. Mean CAS and NOSPECS scores were 0.5 +/- 0.9 (standard deviation) and 4.8 +/- 3.1, respectively. Mean M22-TBII and Mc4-TSI values were 7.5 +/- 10.2 IL/L and 325.9 +/- 210.1 specimen-to-reference control ratio. TSI was significantly correlated with NOSPECS score (R = 0.479, p 0.05), because GO inflammatory activity subsided in the chronic stages of GO. CONCLUSIONS: In chronic-inactive GO after euthyroid restoration, GO activity score did not associate with serum levels of TRAb or TBII. However, levels of the functional antibody Mc4-TSI did correlate with GO severity. Therefore, the TSI bioassay is a clinically relevant measure of disease severity even in chronic inactive GO.

ABSTRACT

PURPOSE: To identify factors associated with care of diabetic retinopathy. METHODS: The fourth Korea National Health and Nutrition Examination Survey (KNHANES IV) is a nationwide survey. This survey included 1, 257 people aged 40 years and older with a history of diabetic mellitus who answered questions, "Within one year, have you ever received eye examination (fundus photography) for screening diabetic retinopathy?" Factors that affect care of diabetic retinopathy were identified using multiple logistic regression analysis. RESULTS: Among the 1,257 people aged 40 years and older, 464 (36.9%) received screening for diabetic retinopathy. People aged 65 years and older (aOR = 0.7, 95% CI: 0.51-0.85) with university education (aOR = 0.5, 95% CI: 0.32-0.74) were more likely to undergo screening for diabetic retinopathy compared to those in the reference category (40-64 years old and those who had elementary school or lower education). People living in rural areas were less likely to undergo screening for diabetic retinopathy compared to those living in urban areas (aOR = 1.7, 95% CI: 1.32-2.24). Diabetic retinopathy screening was also associated with self-reported health status (ref: unhealthy [aOR = 1], fair [aOR = 1.7, 95% CI: 1.25-2.23], and healthy [aOR = 1.8, 95% CI: 1.30-2.44]). CONCLUSIONS: To increase nationwide screening rates for diabetic retinopathy, more attention should be given to underserved groups, particularly people aged between 40 and 64 years, those with a low education level, those living in rural areas, and those with a positive attitude toward self-reported health status. These issues highlight the need for a new emphasis in health education and public health policies aimed towards these underserved groups.
