Social and Clinical Characteristics of Immigrants with Tuberculosis in South Korea

PURPOSE: To determine the social and clinical characteristics of immigrants with tuberculosis (TB) in South Korea. MATERIALS AND METHODS: The registered adult TB patients who were diagnosed and treated in Korea Medical Centers from January 2013 to December 2015 were analyzed retrospectively. A total of 105 immigrants with TB were compared to 932 native Korean TB patients. RESULTS: Among these 105 immigrants with TB, 86 (82%) were Korean-Chinese. The rate of drug-susceptible TB were lower in the immigrants group than in the native Korean group [odds ratio (OR): 0.46; 95% confidence interval (CI): 0.22–0.96, p=0.035]. Cure rate was higher in the immigrant group than in the native Korean group (OR: 2.03; 95% CI: 1.26–3.28, p=0.003). Treatment completion rate was lower in the immigrant group than in the native Korean group (OR: 0.50; 95% CI: 0.33–0.74, p=0.001). However, treatment success rate showed no significant difference between two groups (p=0.141). Lost to follow up (default) rate was higher in the immigrant group than in the native Korean group after adjusting for age and drug resistance (OR: 3.61; 95% CI: 1.36–9.61, p=0.010). There was no difference between defaulter and non-defaulter in clinical characteristics or types of visa among these immigrants (null p value). However, 43 TB patients with recent immigration were diagnosed as TB even though they had been screened as normal at the time of immigration. CONCLUSION: Endeavor to reduce the default rate of immigrants with TB and reinforce TB screening during the immigration process must be performed for TB infection control in South Korea.

Regression of Advanced Hepatocellular Carcinoma with Lung Metastasis in Response to Sorafenib

Sorafenib is a multi-targeted tyrosine kinase inhibitor that inhibits Raf kinase and the vascular endothelial growth factor receptor intracellular kinase pathway and is the first agent to demonstrate a statistically significant improvement in overall survival for patients with advanced hepatocellular carcinoma (HCC). However, there were few cases of partial or complete response reported in the previous studies. We herein report a case of dramatic partial response in a patient who had advanced HCC with multiple lung metastasis and portal vein thrombosis treated with sorafenib.
