[Seroepidemiology of celiac disease among blood donor in Golestan province]

Celiac is a digestive disease. In this disease, small bowel is damaged and the absorption of nutrients are adversely affected. These patients do not absorb gluten. There is probably a correlation between esophagus cancer and celiac. The aim of this research was to study the seroepidemiology celiac disease in this area with high prevalency of esophagus cancer. This research was a descriptive study, which was performed on blood donors in Golestan province during the year 2005-06. blood samples were taken from 2547 subjects. tTG-IgA determination were carried out using ElISA technique, the titre<4U/ml, 4-10U/ml and >10Um/l were considered to be as negative, weakly positive and positive respectively. EMA antibody assessment were carried out on all sample population with more than 4U/ml, using IFA method. 28 subjects [1.1%] had tTG-Ab positive test, out of this number 18 subjects [0.7%] were weakly positive and 10 persons [0.4%] were considered to be positive. EMA test were positive in 70% of subjects with tTG positive results. There was not any significant meaning between positive tTG test and ethnicity from weakly positive tTG, 15 subjects [83.3%] and 3 subjects [16.7%] were male and female respectively. The entire tTG positive were male subjects. In regard to high prevalency of esophagus cancer in the region and the relation of celiac disease with above cancer, it seems necessary to look more seriously at the celiac disease

[Frequency of hepatitis B virus, hepatitis C virus and Human Immunodeficiency Virus in blood donors and patients in Gorgan blood transfusion organization in 2003]

Consultation prior to blood donation and screening tests of common blood born diseases such as Hepatitis B,C and AIDS are very important issue in blood quality assurance, therefore we decided to compare frequency of such diseases in blood donors and outpatients admitted in the blood transfusion centers. For this purpose the initial tests including HBsAg, HCVAb, and HIVAb were performed on all blood donors and outpatients' blood samples in Gorgan transfusion center by ELIZA methods during 2003 and confirmatory tests including neutralization for HBsAg, RIBA for HCVAb and Western blot for HIVAb performed in condition where ELIZA report was positive. The blood donor in this study had the following positive results: HbsAg 2.5%, HCVAb 3%, HIV 0.35%. The same indeces for the out patients were positive as follow: 13%, 8.3% and 2.04% respectively. The other finding from this investigation indicate that the blood donors positive cases with the ELISA technique were confirmed by Western blot 92%, 20.1% nad 0% for HBSAg, HCVAb, as HIV respectively. The confimatory results of the positive out patient's cases were as follow, 97%, 47% and 60% for HBSAg, HCVAb and HIV respectivley. This study reveals frequency of Hepatitis B and C and AIDS among outpatients which considered being high risk group are more than the blood donors. We conclude that the measurement of HBSAg by ELIZA methodes in comparision to the HCV and HIV are more accurate
