Title of Research : ABO BLOOD GROUP SECRETOR STATUS IN AUTOIMMUNE DISEASES PATIENTS
 
Field of Research : Others
 
Preliminary Research Design : Descriptive Study
 
Preliminary Research Type : Basic
 
Preliminary Justification : Individuals who carry the FUT2 gene are termed ABO secretors, because they can form the H, A and B antigen which are produced in epithelial cells and reside on mucins in secretions (Shaz, 2009). ABH non-secretors tend to have a variety of autoimmune diseases such as ankylosing spondylitis, reactive arthritis, psoriatic arthropathy, Sjogren’s syndrome, multiple sclerosis, and Grave’s disease (D'Adamo & Kelly, 2001). The secretor status can be detected from saliva by absorption-inhibition method. Secretors have blood group antigen in their saliva, which can react with the diluted antisera and no agglutination can be seen while red blood cells antigens are added. And vice-visa, agglutination means non-secretor. Some studies showed that non-secretor status has statistically significant association with some autoimmune diseases. For instance, Dickey and colleges found that non-secretor state is significantly associated with coeliac disease (Dickey et al., 1994). As the expression of Lewis antigen is correlated with the ABH antigen secretor status (Bharath & Arumugam, 2016), Le/b-negative non-secretor-individuals are more susceptible to pemphigus vulgaris (Shahidi-Dadras & Golfeshan, 2016).
 
Preliminary Aim : To determine the ABO blood group secretor status of patients with autoimmune diseases
 
Preliminary Objectives : (1) To find out the association of ABO blood group secretor status and autoimmune diseases (2) To compare the ABO blood group secretor status in autoimmune diseases patients and control group
 
Preliminary Sample Size : Already diagnosed autoimmune diseases patients Blood donors will be selected as control group, Sample Size n = (r+1)/r * (p)(1-p)(Zβ+Zα/2)2 / (P1-P2)2 P1 (P case exposed) = OR * Pcontrol exp / P control exp * (OR-1)+1 Odds ratio = 2.5 (Minimum Odds Rati
 
Preliminary Study Duration : one year
 
Preliminary Study Area : Yangon, Myanmar
 
Preliminary Study Method : convenient sampling method
 
Preliminary Research Outcome : Finding out the association of blood group secretor status in autoimmune diseases can aid in the diagnosis of autoimmune diseases. This study can provide the scientific data for autoimmune diseases patients concerning secretor status. Data from this study
 
Preliminary Research Finding : Randomly collected autoimmune disease patients in this study comprised systemic lupus erythematosus (51 %), rheumatoid arthritis (26 %), progressive systemic sclerosis (14 %), mixed connective tissue diseases (5 %), overlapping syndrome (2 %), immune vasc
 
Preliminary Progress Report : Each 100 samples from patient and control group have been collected and performed for ABO grouping and blood group secretor status.
