Background: Most cases of Graves' disease have been treated by antithyroid drugs in Korea. The major drawbacks of antithyroid drugs are the relative high rate of relapse and the inconvinience of long term therapy. Measurement of TBII and TRH stimulation test have been considered as the most reliable tests predicting relapse, but the predictive power is not high enough to use in clinical situation. This study was performed to find good prognostic indicators in Graves' disease patients after the discontinuation of antithyroid drug therapy. Subjects and methods : We restrospectively evaluated 96 patients with Graves' disease who showed normal TRH test at the end of antithyroid drug therapy and were followed for more than one year. Serum T3, T4, T3/T4 ratio, TBII, Anti-TPO Ab and TGAb levels were measured at the time of diagnosis and at the end of therapy. Two to three months after withdrawal of antithyroid medication, serum TSH and free T3 responses to TRH were examined. These parameters were compared between the relapse group and the remission group. Results : Among the 96 patients, 22 patients(22.9%) relapsed(Group Ⅱ) and 74 patients(77.1%) remained in remmision(Group Ⅰ). No significant difference was observed between the relapse and the remission group in clinical parameters, serum T3, T4, TSH, T3/T4 ratio, TBⅡ and Anti-TPO Ab determined before and after treatment. Serum TSH and free T3 levels measured after TRH stimulation were also similar in both groups. Serum TGAb levels determined at the end of treatment were significantly higher in the remission group(p<0.05). Relapse following the discontinuation of therapy occured within 24 months in 72.7% of the relapsed cases. After 24 months, relapse rate was reduced significantly. Conclusion : These results suggest that high serum TGAb levels could be a favorable prognostic indicator for the long term remission of Graves' disease treated with antithyroid drugs, and may suggest that Hashimoto's thyroiditis is combined with Graves' disease in those patients.

Background : Since highly active antiretroviral therapy has lengthened the life span of individuals infected with human immunodeficiency virus (HIV), the importance of malignancy associated with HIV has been increased. The relative frequencies of malignancies in HIV infected patients may vary in different race and region. The aim of this study is to determine the prevalence and characteristics of malignancies in patients with HIV infection in South Korea. Materials and Methods : To identify HIV patients with malignancy, we reviewed the electronic database of pathological reports for all HIV-infected patients seen from January 1986 to December 2005 at the Seoul National University Hospital. We retrospectively reviewed the medical records of them. Results : Among 850 patients infected with HIV, 33 episodes of malignant diseases were diagnosed in 32 patients (3.76%). Thirty were males, and median age was 46 years (range 29-70). At the time of the diagnosis of malignancy, median CD4^(+) lymphocytes count was 100/uL (range 5-620) and in 27 (82%) patients, CD4^(+) lymphocytes count were less than 200/uL. For 13 patients (40%), malignancy was initial presentation of HIV infection. Excluding patients initially diagnosed as malignancy, median follow-up duration from the first visit to diagnosis of malignancy was 36 months (range 3-96). Non-Hodgkin's lymphoma was the most frequent malignancy (13 patients), followed by Kaposi's sarcoma (7), Hodgkin‘s disease (3), acute myeloid leukemia (1), and other solid cancer (9) including one case of anal cancer associated with human papillomavirus. Among 13 patients with non- Hodgkin's lymphoma, 4(31%) achieved the complete remission after chemotherapy and/or radiation therapy, and had been followed without evidence of recurrence. Conclusion : Malignancy was diagnosed in 3.76% of patients infected with HIV. Non-Hodgkin‘s lymphoma is the most prevalent malignancy in HIV patients in South Korea. 목적 : 효과적인 항레트로바이러스 다제요법이 도입됨에 따라, HIV 감염환자들의 수명이 증가되었고, 이에 따라 HIV 감염환자에서 악성종양의 중요성 또한 증가하고 있다. 본 연구의 목적은 우리나라 HIV 감염환자에서 악성종양의 유병률과 호발하는 악성종양의 특성을 밝히는 것이다. 재료 및 방법 : 1986년부터 2005년까지 서울대학교병원에서 치료를 받은 HIV 감염환자의 의무기록을 후향적으로 분석하였고, 병리학적 검사 결과를 검토하여 악성종양이 진단된 환자들을 대상으로 연구를 시행하였다. 결과 : 총 850명의 환자 중, 32명(3.76%)에서 33예의 악성종양이 진단되어, 악성종양의 발병률은 1,000인년 당13.0명(95% 신뢰구간: 8.6∼17.4명)이었다. 그 중 남자는 30명이었고, 악성종양 진단 당시 연령의 중간값은 46 (29-70)세이었다. 악성종양 진단받을 당시, CD4 림프구 수의 중간값은 lOO/uL (5-620 uL) 이었고, CD4 림프구수가 200/ uL 미만인 환자가 27명(82%)이었다. 악성종양에 대한 검사 도중에 HIV 감염사실이 밝혀진 환자가 13명(40%)이었다. HIV를 진단 받은 후 악성종양이 발병한 환자들에서, HIV 진단 후 악성종양의 발병까지는 평균 36개월(3-96개월)이 걸렸다. 13명의 HIV 감염 환자에서 진단된 비호지킨림프종이 가장 흔한 악성종양이었고, 이외에 카포시육종이 7명, 호지킨병이 3명, HPV와 연관된 항문암이 1명의 HIV 환자에서 진단되었다. 그 밖에 급성백혈병, 방광암, 췌장장, 폐암, 진행성위암, 갑상선암, 간세포암, 후두암이 각각 1예씩 진단되었다. 비호지킨림프종이 진단된13명 환자 중, 4명(31%)은 항암치료 및 방사선치료를 받아 완전관해가 되었고, 현재 재발의 증거 없이 외래에서 경과 관찰 중이다. 결론 : 우리나라 HIV 감염환자에서 악성종양의 유병률은 3.76%이었고, 비호지킨림프종이 가장 흔한 악성종양이었다.

Kim Na-Young,Lee Jeong-Sook,Kim Seog-Ji,Park Myoung-Ju,Kim Seok-Hwan The Korean Nutrition Society 2005 Nutritional Sciences Vol.8 No.4

Hepatoprotective effects of the extract of Kochiae fructus (KF), a traditional oriental medicinal plant, were evaluated against carbon tetrachloride($CCl_4$)-induced liver damage in rats. Male Sprague-Dawley rats were divided into control, $CCl_4,\;CCl_4$ plus methanol extract of KF (KFM-$CCl_4$), and $CCl_4$ plus butanol extract of KF (KFB-$CCl_4$) groups. KFM and KFB were orally administered once a day (200 mg/kg body weight) for 14 days. A mixture of 0.2 mL/100 g body weight of $CCl_4$ in olive oil was injected at 30 minutes after the final administration of KFM and KFB. The KFB pretreatment resulted in a significant decrease in the serum transaminase and lactic dehydrogenase levels in the $CCl_4$-treated rats. The $CCl_4$ treatment significantly lowered the activities of glutathione, glutathione reductase (GR), glutathione-S-transferase (GST), superoxide dismutase (SOD), catalase and glutathione peroxidase (GSH-Px). However, pretreatment with KFM and KFB resulted in a significant increase in the glutathione, GR and GST levels. KFB increased the activities of SOD, catalase and GSH-Px, but KFM did not alter them. Pretreatment with KFM and KFB resulted in a significant decrease in the production of aminopyrine N-demethylase in the $CCl_4$-treated rats. KF extract would appear to contribute to alleviate the adveISe effect of $CCl_4$ treatment by enhancing the hepatic antioxidant defense system.

Background: Efficacy and safety of tiotropium bromide, a muscarinic receptor antagonist, in treatment of asthma have been reported. However, its effect on airway remodeling in chronic asthma of the elderly has not been clearly verified. The objective of this study was to investigate the effect of tiotropium and expression of muscarinic receptors as its related mechanism in an aged mouse model of chronic asthma with airway remodeling. Methods: BALB/c female mice age 6 weeks, 9 and 15 months were sensitized and challenged with ovalbumin (OVA) for three months. Tiotropium bromide was administered during the challenge period. Airway hyperresponsiveness (AHR) and pulmonary inflammation were measured. Parameters of airway remodeling, and expression levels of M₂ and M₃ receptors were examined. Results: Total cell with eosinophils, increased in the OVA groups by age, was decreased significantly after treatment with tiotropium bromide, particularly in the age group of 15 months. AHR and levels of interleukin (IL)-4, IL-5, and IL-13 were decreased, after tiotropium administration. In old aged group of 9- and 15-months-treated groups, hydroxyproline contents and levels of α-smooth muscle actin were attenuated. Tiotropium enhanced the expression of M₂ but decreased expression of M₃ in all aged groups of OVA. Conclusion: Tiotropium bromide had anti-inflammatory and anti-remodeling effects in an aged mouse model of chronic asthma. Its effects seemed to be partly mediated by modulating expression M₃ and M₂ muscarinic receptors. Tiotropium may be a beneficial treatment option for the elderly with airway remodeling of chronic asthma.

Korean Association for Clinical Oncology : Slide Session ; OP4-1 : Others ; Target Sequencing of Papillary Renal Cell Carcinoma, Type 2, Using Custom-Made Kidney Cancer Panel

( Ji Yeon Kim ),( Se Hoon Lee ),( Jong Il Kim ),( Jong Yeon Shin ),( Kyung Chul Moon ),( Cheol Kwak ),( Hyeon Hoe Kim ),( Dae Seog Heo ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background:Papillary renal cell carcinoma type2 (PRCC2) has poor prognosis, treatment strategy is not established and the genetic alteration is poorly understood. We sequenced PRCC2 samples using custom-made kidney cancer panel to fi gure out genetic alterations of PRCC2. Methods: We have reviewed publications about the genetics of kidney cancer including all subtypes and selected 55 candidate genes. This cancer panel consisted of 1022 regions by Agilent SureSelect Target Enrichment. We sequenced 12 PRCC2 tumor samples along with 6 paired normal tissue samples. The patients` age were ranged from 26 to 82 year-old, and 3 patients were female (25%). Genomic DNA was isolated from dissected tumor tissue samples (6 fresh, frozen and 6 formalin-fi xed, paraffi n-embedded) and normal tissue samples. Sequencing was performed by Illumina platform and aligned to H. sapiens, hg19, GRCh37. Total probe number was 4103 and size was 283.494 kbp. Results: fifty-four of 55 target genes had 100% coverage, in spite of 92.7% coverage of one target gene. We found two novel FH mutations (one single nucleotide variant and one 5bp indel) and one novel NFE2L2 mutation. Two out of 12 samples (17%) were altered in NRF2 pathway (1 NFE2L2 and 1 KEAP) which was already well-known as driver in PRCC2. Novel PBRM1 mutation in two samples and SETD2 mutation in one sample were identifi ed. In addition, PTEN, TSC1, KDM5C and AKT1 mutation are observed in one case, respectively. No VHL mutation in PRCC2 was revealed. Conclusions: We analyzed somatic mutation of PRCC2 with custom-made kidney cancer panel. We found several candidate driver mutations of PRCC2. Our result reveals that the genetics of PRCC2 is heterogeneous, therefore, the approach using kidney cancer panel could be used to characterize individual PRCC2.

Local tumor invasiveness is more predictive of survival than International Prognostic Index in stage IE/IIE extranodal NK/T-cell lymphoma, nasal type

Kim, Tae Min,Park, Yeon Hee,Lee, Sang-Yoon,Kim, Ji-Hoon,Kim, Dong-Wan,Im, Seock-Ah,Kim, Tae-You,Kim, Chul Woo,Heo, Dae Seog,Bang, Yung-Jue,Chang, Kee-Hyun,Kim, Noe Kyeong American Society of Hematology 2005 Blood Vol.106 No.12

<P>This study was launched to determine the prognostic significance of local tumor invasiveness (LTI) in 114 patients diagnosed with stage IE/IIE extranodal natural killer (NK)/T-cell lymphoma, nasal type (NTCL). LTI was defined as bony invasion or destruction or tumor invasion of the skin. Complete remission (CR), overall survival (OS), and disease-free survival (DFS) were compared between each group according to LTI, Ann Arbor stage, and International Prognostic Index (IPI). LTI was observed in 23 patients. Using multivariate analysis, factors associated with low probability of CR were the presence of LTI (P < .001), the presence of B symptoms (P = .003), and single-modality chemotherapy (P = .045). The presence of LTI (relative risk [RR] = 8.4, 95% confidence interval [CI] 3.9-17.9; P < .001) and high IPI score (RR = 2.8, 95% CI 1.2-6.8; P = .019) were also predictive of OS. The presence of LTI (RR = 7.3, 95% CI 3.2-16.5; P < .001) was an independently significant factor for reduced DFS. Ann Arbor staging system did not predict CR, OS, or DFS but IPI did have predictive power with regard to survival outcome. LTI is the most important prognostic factor in predicting low probability of CR and reduced OS and DFS in nasal stage IE/IIE NTCL.</P>

Chronic hemodialysis patients frequently experience hemodialysis(HD)-related side effects caused by excessive ultrafiltration and abrupt change of osmolality. Sodium ramping in HD is known to reduce ultrafiltration-related side effects, but it frequently induces symptoms related to sodium overload. We wanted to know the relationship between blood volume changes and the side effects related to ultrafiltration during hemodialysis and whether we can individualize various sodium ramping methods according to the effect of change in blood volume( BV) and side effects of sodium ramping. We studied 9 hypotension-prone patients during HD. The duration of the study lasted for 5 weeks, each week using different sodium ramping protocols: protocol 1; dialysate [Na+] of 140mEq/L, protocol 2; dialysate [Na?] same as the predialysis serum [Na+], protocol 3; dialysate [Na+] was 20mEq/L greater than that of the patient's serum for 1hr, 10mEq/L greater than patient's serum [Na+] for 2hr and then the same as patient's serum] for the last 1hr, protocol 4; at the beginning of dialysis, dialysate sodium was ramped to 20mEq/L above the patient's serum sodium and then on a straight linear fashion lowered to the predialysis serum [Na+] at the end of dialysis, protocol 5; sodium was constantly ramped to 10 mEq/L above serum [Na+]. We measured the BV with Crit-Line IIR(In-Line Diagnostics, Corp., Riverdale, USA), the blood pressure during each HD and interdialytic weight gain. We documented subjective symptoms which occurred during the 5 treatment protocols by patient's questionnaire after each HD. The results were as follows. 1) The mean age of the patients(M:F=3:6) was 54.1years and 6 patients were diabetics. 2) There was no significant difference in the BV among the 5 protocols in both whole study population and individual. Neither was there a statistically significant difference in the BV with respect to hypotension during HD. 3) There were no episodes of hypotension(P value $lt;0.001) with protocols 3, 4, 5 compared to protocs 1 and 2. 4) Three patients during protocols 4 and 5 experienced more thirst after HD than during protocol 1 and one patient during protocol 4, 5 had more interdialytic weight gain than the protocol 1. As a whole, patients while on protocol 4 & 5 experienced more thirst than protocol 1 but patients during protocol 3 experienced the same degree of thirst as protocol 1. In summary, sodium ramping reduced HD-related side effects but this benefit could not be explained on the basis of blood volume change measured by the Crit-Line IIR. Protocol 3 may be more appropiate sodium ramping method in 4 of the 9 patients. These data suggest that protocol 3 may be used before protocol 4, 5 when we apply sodium ramping to the patients who frequently have hypotension during HD.
