Purpose : High interleukin-1 beta(IL-$1{\beta}$) expression in the skin biopsy specimens of patients with Henoch-$Sch\ddot{o}nlein$ Purpura(HSP) has been observed. We examined IL-$1{\beta}$ gene polymorphism in patients with HSP. The purpose of this study is to examine the relationship between IL-$1{\beta}$ gene polymorphism and renal involvement in HSP. Methods : Patients from mideast Korea with HSP were studied. All patients had at least 6 months of follow up. Patients and ethnically matched controls were genotyped for IL-$1{\beta}$ gene polymorphism by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). Results : Thirty-four patients(all younger than 15 years old) who had been diagnosed with HSP and 27 controls were examined. No allele or genotype differences between the HSP and control groups were observed. No significant association between the carriage of IL-$1{\beta}$(-511) T allele and renal involvement(P=0.525, OR:1.417, CI:0.545-3.686) was found. Conclusion : In unselected patients with HSP, carriage of IL-$1{\beta}$(-511) T allele does not appear to influence renal involvement.

The aim of this research was to investigate the possible association between gastric carcinoma (GC) and polymorphisms of the IL-$1{\beta}$ gene in the Kashmiri population using peripheral blood DNA from 150 gastric carcinoma cases and 250 population controls with detailed data for clinicopathological characteristics of the disease. Two SNPs in the IL-$1{\beta}$ gene were selected for this study. Expression of IL-$1{\beta}$ was studied in 50 gastric carcinoma cases using immunohistochemistry and RT-PCR and then correlated with genotype. The frequency of the IL-$1{\beta}$-511 C allele was significantly higher in the GC case group (53.3%) than in controls (45.4%) with an odds ratio (OR) of 0.73 and a P value of 0.03. Multivariate regression analysis showed associations of gastric carcinoma with mutant form of IL-$1{\beta}$-511 TT (OR 0.309; P value <0.001) and the CC genotype of IL-$1{\beta}$-31 (OR 0.313; P value of 0.002). Haplotype analysis of IL-$1{\beta}$-31 and IL-$1{\beta}$-511 showed decreased association of IL-$1{\beta}$-31 T with IL-$1{\beta}$-511 C with gastric carcinoma (OR 0.728; P value 0.03). Expression study of 50 samples by immunohistochemistry (IHC) and RT-PCR showed association with grade III and stage III+IV. After correlating the expression with polymorphism no association was found.

Objectives : Pro-inflammatory cytokines are related to the pathophysiology of both cancer and depression, and their secretion is controlled by the transcriptional activity of particular gene polymorphisms. This study aimed to investigate whether interleukin (IL)-1β -511C/T gene polymorphism is associated with depression following mastectomy for breast cancer. Methods : A total of 309 patients with breast cancer were evaluated one week after mastectomy, and 244 (79%) were followed one year later. Depression (major+minor depressive disorders) was diagnosed according to DSM-IV criteria using the Mini International Neuropsychiatric Interview, and classified into prevalent, persistent, and incident depression. Associations of IL-1β -511C/T polymorphism with the three depressive status were estimated using logistic regression models. Results : At baseline, 74 (24%) patients were classified with prevalent depression ; and at follow up, 19 (8%) and 25 (10%) patients were classified with persistent and incident depression, respectively. The IL-1β -511T/T genotype was independently associated with prevalent and persistent depression, but not with incident depression. Conclusion : IL-1β -511T/T genotype may involve in the etiology of depression occurring in women with breast cancer who receive a mastectomy.

Objective : Major depression is known to have immunologic dysfunctions, the recent studies revealed that cytokines including IL-6 and IL-$1{\beta}$ were increased in patients with major depression. Since molecular genetic methods have been progressed, this study was to investigate the relationship between major depression and immunologic aspects by analyzing polymorphism of IL-10 gene. Method : 92 patients with major depression were included and data of 146 normal controls obtained from the Catholic Hemopoietic Stem Cell Information Bank of Korea were used in this study. DNA was extracted from whole blood, thereafter amplified by polymerase chain reaction, and digested by Mae III After that procedure, we obtained and assessed RFLP of two alleles, IL-10T and IL-10C. All data were analyzed by ${\chi}^2$ test. Results : 1) There were no significant difference in genotype frequencies of $IL-10^*T/T$, $IL-10^*T/C$, and $IL-10^*C/C$ between major depression patients group and control group. 2) There were no significant difference in allelic frequencies of $IL-10^*T$ and $IL-10^*C$ between major depression patients group and control group. Conclusion : We did not verified the differences in frequencies of $IL-10^*T/^*IL-10^*C$ gene between the major depression patients group and control group, respectively. But the results of this study do not declare that the IL-10 gene has no association with major depression. We do suggest that further systematic studies including various clinical variables should be conducted.

Background/Aims: Several epidemiological studies have validated the association of interleukin gene polymorphisms with acute pancreatitis (AP) in different populations. However, there have been few studies in Asian ethnic groups. We aimed to investigate the relationships between inflammatory cytokine polymorphisms and AP as pilot research in a Korean ethnic group. Methods: Patients who had been diagnosed with AP were prospectively enrolled. DNA was extracted from whole blood, and DNA sequencing was subsequently performed. Single-nucleotide polymorphisms (SNPs) of the interleukin $1{\beta}$ (IL1B), interleukin 1 receptor antagonist (IL1RN), and tumor necrosis factor ${\alpha}$ (TNFA) genes of patients with AP were compared to those of normal controls. Results: Between January 2011 and January 2013, a total of 65 subjects were enrolled (40 patients with AP vs. 25 healthy controls). One intronic SNP (IL1RN -1129T>C, rs4251961) was significantly associated with the risk of AP (odds ratio, 0.304; 95% confidence interval, 0.095 to 0.967; p = 0.043). However, in our study, AP was not found to be associated with polymorphisms in the promoter regions of inflammatory cytokine genes, including IL1B (-118C>T, c47+242C>T, +3954C/T, and -598T>C) and TNFA (-1211T>C, -1043C>A, -1037C>T, -488G>A, and -418G>A). Conclusions: IL1RN -1129T>C (rs4251961) genotypes might be associated with a significant increase of AP risk in a Korean ethnic group.

Recently epidemiologic studies have indicated that the patients with periodontitis may have increased risk of ischemic cardiovascular events, and have suggested the important roles of blood cytokines and acute reactant proteins in the systemic infection and inflammatory response. Periodontitis and coronary heart disease (CHD) may share the common risk factors and the genetic mechanism associated with interleukin(IL)-1A, B and RA genotype may be involved in the production of IL-1. This study was aimed to investigate the relationship between angiographically defined CHD and periodontitis as chronic Gram-negative bacterial infection and to determine whether the IL-1 gene polymorphism is associated in both diseases. Patients under the age of 60 who had undergone diagnostic coronary angiography were enrolled in this study. Subjects were classified as positive CHD (+CHD, n=37) with coronary artery stenosis more than 50% in at least one of major epicardial arteries, and negative CHD (-CHD, n=30) without significant stenosis. After recording the number of missing teeth, periodontal disease severity was measured by means of plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), and radiographic bone loss around all remaining teeth. Gingival crevicular fluid (GCF) was collected from the 4 deepest periodontal pockets and assessed for cytokine ($IL-1{\beta}$, IL-6, IL-1ra, tumor necrosis $factor-{\alpha}$, and prostaglandin $E_2$). Additionally, blood CHD markers, lipid profile, and blood cytokines were analyzed. IL-1 gene cluster genotyping was performed by polymerase chain reaction and enzyme restriction using genomic DNA from buccal swab, and allele 2 frequencies of IL-1A(+4845), IL-1B(+3954), IL-B(-511), and IL-1RA(intron 2) were compared between groups. Even though there was no significant difference in the periodontal parameters between 2 groups, GCF level of $PGE_2$ was significantly higher in the +CHD group(p<0.05). Correlation analysis showed the positive relationship among PD, CAL and coronary artery stenosis(%) and blood $PGE_2$. There was also significant positive relationship between the periodontal parameters (PI, PD, CAL) and the blood CHD markers (leukocyte count, C-reactive protein, and lactic dehyrogenase). IL-1 gene genotyping showed that IL-1A(+3954) allele 2 frequency was significantly higher in the +CHD group compared with the -CHD group (15% vs. 3.3%, OR 5.118,p=0.043). These results suggested that periodontal inflammation is related to systemic blood cytokine and CHD markers, and contributes to cardiovascular disease via systemic inflammatory reaction. IL-1 gene polymorphism might have an influence on periodontal and coronary heart diseases in Korean patients.

목 적 : IL-1ra는 항염증반응을 가지고 있는 인자로서 IL-1 수용체와 결합하여, IL-l$\alpha$와 IL-1$\beta$의 결합을 경쟁적으로 억제시킴으로써, IL-1에 의해 매개되는 다양한 질환에서 중요한 내인성 조절인자로 작용한다. 이 유전자의 intron 2 부위에 86 bp 크기를 가지는 tandem repeat 에 의한 유전자 다형성이 존재하는데, 다양한 자가면역질환에서는 allele 2형의 빈도가 정상 인구군에 비해 유의하게 높다는 사실이 밝혀져 있다. 이에 저자들은 Henoch-$Sch{\ddot{o}}nlein$ Purpura 환자들을 대상으로 IL-1ra 유전자의 variable number tandem repeats(VNTR) 다형성을 검사하여 정상 대조군과 비교하였으며, 신장 침범 여부 및 중증의 경과에 $IL1RN^{*}2$가 어떤 영향을 미치는 지를 조사하였다. 방 법.: 1998년 1월부터 2002년 12월까지 부산 백병원 .소아과를 방문하여 Henoch-$IL1RN^{*}2$ purpura로 진단된 74명의 환자와 정상 대조군 43명을 대상으로 하였다. EDTA 처리된 전혈에서 상품화된 DNA 추출키트($QIAamp^{\circledR}$ DNA Blood Mini kit, Quiagen, USA)를 사용하여 DNA를 추출하였다. IL-1ra 유전자 다형성(polymorphysm)은 86 bp의 2, 3, 4, 5번의 반복횟수에 따라 각각 240 bp, 325 bp, 410 bp 또는 500 bp 크기의 밴드를 확인하여 결정하였다. 결 과 : HSP 환자군과 정상 대조군 모두에서 $IL1RN^{*}1$의 allele 빈도가 각각 $93.9\%,\;93.2\%$로 가장 높았으며, carriage rate도 각각 $98.6\%,\;97.9\%$로 가장 높았다. $IL1RN^{*}2$의 allele 빈도는 HSP 군에서 4.7$\%$로 대조군의 2.5$\%$에 비해 높았으나, 통계적으로 유의하지 않았다(P=0.794). Carriage rate도 HSP군에서 8.1$\%$로 대조군의 6.8$\%$에 비해 높았으나, 통계적으로 유의하지 않았다(P=0.915). $IL1RN^{*}2$의 allele 빈도는 신장 침범군에서 6.3$\%$로 비침범군의 2.9$\%$에 비해 높게 나타났으나 통계적으로 유의하지 않았다(P=0.356). Carriage rate는 신장 침범군에서 10.0$\%$, 비침범군에서 5.9$\%$였으며, 양군 사이에는 유의한 차이가 관찰되지 않았다(P=0.523). 24시간 채집뇨에서 측정한 총단백량이 1,000 mg 이상이었던 경우가 13명이었는데, 이들의 allele형은 $IL1RN^{*}1$이 11명이었으며, $IL1RN^{*}2와\;IL1RN^{*}4$형이 각각 1명씩 있었다. 마지막 추적관찰 시점까지 단백뇨가 지속되었던 환자는 4명이었으며 이들은 모두 $IL1RN^{*}1$형 이었다. 결 론 : HSP 환자군과 정상 대조군 모두에서 $IL1RN^{*}1$의 allele 빈도와 carriage rate가 가장 높았다. $IL1RN^{*}2$ allele 빈도와 carriage rate는 HSP 환자군에서 대조군과 비교하여 유의한 차이가 관찰되지 않았다. 또한 HSP 환자군에서도 $IL1RN^{*}2$ allele 빈도와 carriage rate는 신장 침범의 정도와도 유의한 관련성이 발견되지 않았다.

Interleukin-12 (IL-12) as an antitumor and interleukin-6 (IL-6) as an inflammatory cytokine, are immunomodulatory products that play important roles in responses in cancers and inflammation. We tested the association between two polymorphisms of IL-12(1188A>C; rs3212227) and IL-6 (-174 C>G) and the risk of bladder cancer in 261 patients and 251 healthy individuals. We also investigated the possible association of these SNPs in patients with high-risk jobs and smoking habits with the incidence of bladder cancer. The genotype distributions of IL-6 (-174 C/G) genotype were similar between the cases and the control groups; however, among patients with smoking habits, the association between IL-6 gene polymorphism and incidence of bladder cancer was significant. After a control adjustment for age and sex, the following results were recorded: CC genotype (OR= 2.11, 95%CI=1.56-2.87, p=0.007), GC genotype (OR=2.18, 95%CI=1.16-4.12, p=0.014) and GC+CC (OR=2.6, 95%CI=1.43-4.47, p=0.011). A significant risk of bladder cancer was observed for the heterozygous genotype (AC) of IL-12 (OR=1.47, 95%CI=1.01-2.14, p=0.045) in all cases, and among smokers (AC) (OR=3.13, 95%CI=1.82-5.37, p=0.00014), combined AC+CC (OR=3.05, 95%CI=1.8-5.18, p=0.000015). Moreover among high risk job patients, there was more than a 3-fold increased risk of cancer in the carriers of IL-12 beta heterozygous (OR=3.7, 95%CI=2.04-6.57, p=0.000056) and combined AC+CC(OR=3.29, 95%CI=1.58-5.86, p=0.00002) genotypes as compared with the AA genotype with low-risk jobs. As a conclusion, this study suggests that IL-12(3'UTR A>C) and IL-6 (-174 C>G) genotypes are significantly associated with an increased risk of bladder cancer in the Iranian population with smoking habits and/or performing high-risk jobs.
