Serologic tests criteria in various sexual and age groups of patients in Kermanshah province from 2003 to 2007

Background: Serologic tests are current diagnostic criteria in Brucellosis recognition. Their dispersal among brucellosis patients either evaluate identification system of patients or help physicians in useful application of these tests.
Materials and methods: In this study, the criteria of serologic tests (Wright, Coombs Wright, and 2ME) was collected and from patients between 2003 and 2007 then analyzed. The reverse logarithms bases of 10 were applied to convert the values to normal dispersal values. The relationship of recent values with age groups (ten-year groups), sex, and the year of diagnosis was evaluated by ANOVA test.
Results: 3554 cases of Wright test were found in forms of which had two modes of 1. 160 (25%) and 1. 320(25%). The criteria for men were greater then for women (p<0. 01). The criterion was decreased until the initial of 5th decade of life and the average of test criterion for 2004 and 2005 was greater for 2003 and 2007 (p<0. 01). Each factor (age (p<0. 01), sex (p<0. 05), and the year of diagnosis (p<0. 05)) were correlated
independently with the average titer of Wright test, and the variance of titers were different in various sexes and sexual groups (p<0. 05). A pattern of similar variations and relationships could be recognized about 2ME and Cooms-Wright tests, as well.
Conclusion: Criteria of disease tests in symptomatic patients of Brucellosis were age and sex related and the average in diminution of disease incidence time (2004 and 2005) is greater than in increase time (2003 and 2007).
