Abstract: To investigate chronic immune effects of polychlorinated biphenyl (PCB) and polychlorinated dibenzofuran (PCDF), anti-SSA/Ro and anti-SSB/La antibodies were studied in serum of 213 patients with Yusho and 63 control subjects in 2013. Anti-SSA/Ro antibodies were found in 4.2% (9/213) of patients with Yusho and 1.6% (1/63) of control subjects. The prevalence rates of anti-SSA/Ro antibodies in Yusho patients were not associated with blood PCB concentration or blood 2,3,4,7,8-pentachlorodibenzofuran (PeCDF) concentration. Anti-SSB/La antibodies were found in 1.4% (3/213) of patients of Yusho, but none of controls. Furthermore, high concentrations of PCB and 2,3,4,7,8-PeCDF were present in Yusho patients with anti-SSB/La antibodies. We conclude that anti-SSB/La antibody is present in patients with Yusho, and it may be associated with PCB and 2,3,4,7,8-PeCDF in the blood. Read more

Abstract: Dioxin and dioxin-like compounds receptor (Ahr) mainly expressed on the surface of regulatory T (Treg) cell and Th17 cell could regulate immunological functions in the Yusho patients. We prospectively analyzed data obtained in a total of 56 cases of Yusho, which include patients identified ('Nintei') or non-identified ('Minintei') or identified as a family member, at the annual health check in 2014. The number of Treg cell showed lower among identified patients compared with non-identified group or family identified group (p = 0.4184 and p= 0.291, respectively). There was also a strong correlation between serum levels of neutral fat and the number of Treg cells (p=0.0313). These results suggest that Treg cell plays a principal role in the immune response among Yusho patients. Read more

Abstract: Maternal exposure to dioxins causes a number of developmental disorders in the offspring. Previous studies have suggested that lactational exposure to 2,3,7,8-tetrachlorodizenzo-p-dioxin (TCDD) reduces the pup level of thyroid hormone after weaning, leading to the damage to their development including neural maturation. However, the specificity for age and dioxin congeners as well as dose dependency in terms of a reduction in pup thyroid hormone remains to be clarified. To address this issue, we investigated whether TCDD or 2,3,4,7,8-pentachlorodibenzofuran (PenCDF), one of the dioxins which caused 'Yusho' incident, affects the status of thyroid hormone during the fetal and neonatal periods. Treating pregnant rats at gestational day (GD) 15 with 1μg/kg TCDD scarcely affected the serum concentration of thyroxine, although a significant reduction by TCDD was detected at limited endpoints [GD21 and postnatal day (PND) 21]. In addition, maternal exposure to TCDD (0.05-30μg/kg) or PenCDF (1-1,000μg/kg) did not have any change in the serum level of thyroxine in GD20 fetuses even at the maximum dose. Neither the expression of pituitary thyroid-stimulating hormone β (TSHβ) nor hypothalamic thyrotropin-releasing hormone was sensitive to TCDD treatment. In pregnant dams, TCDD decreased the serum level of thyroxine at GD20 and 21, while the pituitary expression of TSHβ was induced. These results suggest that a single administration of dioxins to pregnant rats at GD15 have little effect on the level of thyroxine in the fetuses and infants, while a reduced level of this hormone observed in the offspring at GD21 and PND21 and pregnant dams at GD20 and 21.

Abstract: We examined the bone mineral density in Yusho patients. 460 subjects underwent dual-energy Xray absorptiometry bone scans as part of the nationwide Yusho health examination in 2011. Serum levels of polychlorinated dibenzo-p-dioxin, polychlorinated dibenzofurans, and non-ortho polychlorinated biphenyls were measured using high-resolution gas chromatography and high-resolution mass spectrometry. The average age was 64.0 years in women and 63.4 in men. About one-third (35%) of women (n=89) had low bone mineral density (BMD), defined as a T-score less than 70, while only 4.9% of men (n=10) had low BMD. Serum levels of several congeners were positively associated with Z-scores in simple regression analysis. Further multivariate linear regression analysis should be required in the future. Read more

Abstract: Half-lives of blood levels of 2,3,4,7,8-Pentachlorodibenzofuran (PeCDF) are varied in Yusho patients. The objective was to evaluate a relationship between half-lives of PeCDF levels and types of SNP rs10249788 of aryl hydrocarbon receptor (AHR) gene in 93 Yusho patients. Based on physical symptoms, age, sex, body mass index and other factors, we set up suitable calculation formulas to fit the actual PeCDF levels thorough rates of change in PeCDF.We found that patients with C/T SNP had longer half lives than patients with C/C and T/T SNPs. Patients with T/T SNP are known to express higher amount of AHR mRNAs. However, detailed analysis could not be carried out in T/T group due to a limited number of patients (n=11). Further research is warranted to determine the cause of the longer half-lives in C/T patients. Read more
