Background/Aims: This study compared the prevalence of hepatitis C virus (HCV) infection in the Republic of Korea and estimated the high-risk regions and towns. Methods: National Health Insurance Service data for 8 years from 2005 to 2012 were used. The subjects of the study had visited medical facilities and been diagnosed with or received treatment for acute or chronic HCV as a primary or secondary disease according to ICD-10 codes of B17.1 or B18.2, respectively. Any patient who received treatment for the same disease multiple times during 1 year was counted as one patient in that year. To correct for the effect of the age structure of the population by year and region, the age-adjusted prevalence was calculated using the direct method based on the registered population in 2010. Results: The overall prevalence of HCV infection among Korean adults (>20 years old) increased from 0.14% in 2005 to 0.18% in 2012. The sex-, age-, and region-adjusted prevalence in 2012 was 0.18%. The prevalence was highest in Busan, Jeonnam, and Gyeongnam, and there were towns with noticeably higher prevalences within these regions: Jindo (0.97%) in Jeonnam, Namhae (0.90%) in Gyeongnam, and Seo-gu (0.86%) in Busan. Conclusions: The prevalence of HCV infection differs by regions as well as towns in the Republic of Korea, and is highest in Busan, Jeonnam, and Gyeongnam. The reasons for the high prevalence in these specific regions should be identified, since this could help prevent HCV infections in the future. In addition, active surveillance and treatment policies should be introduced to stop any further spread of infection in these high-prevalence regions. (Clin Mol Hepatol 2015;21:249-256)

Background/Aims: The prevalence of hepatitis C virus (HCV) infection in Busan, Gyeongnam, and Jeonnam Provinces in Korea is more than twice the national average. This study aimed to examine whether demographic and lifestyle characteristics are associated with HCV infection in these areas. Methods: A case control study was performed at three study hospitals. HCV cases were matched with two controls for sex and age. Patient controls were selected from non-HCV patients at the same hospital. Healthy controls were subjects participating in medical checkups. Conditional logistic regression models were used. Results: A total of 234 matched-case and patient- and healthy-control pairs were analyzed. The significant risk factors for both controls were sharing razors (adjusted odds ratio [aOR], 2.39 and 3.29, respectively) and having more than four lifetime sexual partners (aOR, 2.15 and 6.89, respectively). Contact dockworkers (aOR, 1.91) and tattoos (aOR, 2.20) were significant risk factors for the patient controls. Transfusion (aOR, 5.38), a bloody operation (aOR, 5.02), acupuncture (aOR, 2.08), and piercing (aOR, 5.95) were significant risk factors for the healthy controls. Needle stick injuries and intravenous drug abuse were significant in the univariate analysis. Conclusions: More education concerning the dangers of sharing razors, tattoos and piercings is required to prevent HCV infection. More attention should be paid to needle stick injuries in hospitals and the community. (Gut Liver 2016;10:126-132)

Heshouwu (Polygonum multiflorum Thunb.) Extract Attenuates Bone Loss in Diabetic Mice

This study investigated the effects and mechanism of Heshouwu (Polygonum multiflorum Thunb.) water extract (HSW) on diabetes-related bone loss in mice. HSW was orally administered (300 ㎎/㎏ body weight) to high-fat diet and streptozotocin-induced diabetic mice for 10 weeks. HSW significantly alleviated mouse body weight loss and hyperglycemia compared with the control group, and elevated serum levels of insulin, osteocalcin, and bone-alkaline phosphatase. HSW supplementation also significantly increased the bone volume/tissue volume ratio and trabecular thickness and number, and decreased the bone surface/bone volume ratio and trabecular structure model index in the femur and tibia. Moreover, HSW significantly increased femoral bone mineral density. In addition, HSW down-regulated osteoclastogenic genes, such as nuclear factor of activated T-cells, cytoplasmic 1 and tartrate-resistant acid phosphatase 5 (TRAP), in both the femur and tibia tissue, and reduced serum TRAP level compare to those of control mice. These results indicate that HSW might relieve diabetes-related bone disorders through regulating osteoclast-related genes, suggesting HSW may be used as a preventive agent for diabetes-induced bone loss.
