The evaluation of HLA class I association with allergic Asthma

Abstract

Major histocompatibility complex (MHC), which plays a major biological function in immune response, is generally associated with so many human disease. During recent years a new clinical relevance of MHC disease. On the other hand there is a strong correlation between some autoimmune diseases and MHC system such as in some allergic abnormalities and its relation with HLA antigens. In order to investigate this concept 30 atypic asthmatic patients and 100 healthy controls were selected. Human leukocyte antigen (HLA) typing was performed by standard NIH procedures and the results analyzed. The frequency of HLA-A2, A11, Aw19 and HLA-B51 decreased in atypic asthmatic patients with no association recorded significantly between HLA-C and allergic asthma. The results of our study indicated that there was a significant relationship between allergic asthma and HLA-I antigens.
