BACKGROUND
A high prevalence of gastroesophageal reflux disease(GERD) has been reported in diabetic patient. However, the exact mechanisms of GERD in diabetic patient have not been described. In several studies, diabetic neuropathy and dysfunction of the autonomic nervous system have been suggested as risk factors of GERD. However, there have been no studies on the exact prevalence or risk factors of GERD in Korean diabetic patients. Therefore, the prevalence of GERD in Korean diabetics patients was examined, and the risk factors for GERD, the differences in symptoms between GERD and non-GERD patients, and the degree of symptom relief after treatment were also analyzed. METHODS: A total of 310 diabetic patients, who underwent an upper gastroendoscopy due to diverse gastrointestinal symptoms, between April 2001 and November 2003, were enrolled. The diagnostic criteria or GERD included the upper gastroendoscopic view, which was analyzed using the scale of 'The Los Angeles Classification of Esophagus' from grades A to D. The prevalence and symptoms of GERD patients and the variable risk factors, such as blood glucose level, smoking and diabetic neuropathy, were examined. RESULTS: 1) There was an 18.4% prevalence of GERD in diabetic patients. 2) The clinical characteristics, including sex, age and serum lipid level, of the GERD group were not significantly different to those of the control group. However, the duration of smoking, the fasting and postprandial 2-hour serum glucose levels, and the diabetic neuropathy significantly affected GERD, 3) The main symptoms of the GERD group were dyspepsia(47.4%) and heart burn(26.3%). 4) The degree of subjective symptom relief in the GERD group after treatment with the proton pump inhibitor, pantoprazole(40mg), was remarkably lower than in the control group for approximately 1 month. CONCLUSION: In this study, the prevalence of GERD in diabetic patient was higher than that found in the general population which suggests that GERD in diabetic patient was due to a poorly controlled serum glucose level and diabetic neuropathy. The chief complaints pertaining to gastrointestinal symptoms in both study groups were non-specific. However, the recovery from symptoms in the GERD group was lower than the control group following drug therapy. The causes of the lower response rate in the GERD group will need to be examined in further studies.

BACKGROUND
Although the HLA class II genes are cleaily associated with insulin-dependent diabetes mellitus(IDDM) in all ethnic. Groups, considerable variation in the associated genotypes is observed among the different ethnic groups. Mathods: In order to estimate what degree genetic and environmental determinants influence the true incidence of IDDM, ICA by imrnunohistochemistry, anti-GAD prevalence by radioimmunoprecipitation and HLA-DRB1, DQAl, and DQB1 polymorphisms after PCR amplification of genomic DNA were analyzed in 131 cases of IDDM, whose age at diagnosis were less than 15. RESULTS: 56% of them(73/131) were anti-GAD positive. 43% IDDM(56/131) were ICA positive. HLA DR3 and DR9 were susceptibility markers, whereas DR2 and DR5 were protective markers. DR3/4,, DR3/9, and DR3/X(X: other than 3, 4) were susceptible genotypes. HLA DQA1*0301 allele was increased, and DQB1*0301 and DQB1*0602 were decreased in IDDM. Not only HLA DQA1 Arg, but also DQBl non-Asp were found to be independent marker for IDDM, but their strength of association was weak. The highest prevalence of anti-GAD was observed in thosc homozygous for DR4(87.5%), exceeding that(47.8%) in those without this allele, and those with one DR4(63.5), whereas the highest prevealence of ICA was found in those homozygous for DR3(10G%), exceeding that in those with one DR3(64.3%) or in those without this allele(36.7%). There was a significant difference in numbers of HLA DQ susceptibility heterodimers in anti-GAD positive or negative patients. Conelusion: The prevalence of islet-specific auto-antibodies were present at comparable sensitivity and specificity in Korean IDDM patients. We could also assess that the immunoenetic markers for IDDM among Caucasians likewise confer disease susceptibility among Koreans. However, different HLA susceptibility alleles and a lower strength of association with known susceptibility markers, presumably because of differences in the genetic make-up of the population or in linkage disequilibrium patterns compared with other racial groups.
