Abstract: Childhood asthma, often associated with atopy, is more common in boys and may persist throughout life in 50% of cases. This case-control study was carried out to examine if any association of paediatric bronchial asthma with human leukocyte antigen (HLA) class I antigens. Thirty-six children with bronchial asthma diagnosed on basis of Global Initiative for Asthma (GINA) criteria and an equal number of healthy controls without history of bronchial asthma were studied. Low resolution HLA- ABC typing was performed by sequence specific primers (SSP) and the frequency of HLA–ABC antigens in the two groups was compared. Total serum immunoglobulin E (IgE) estimation was done as a marker of atopy by ELISA. The study included 24 boys and 12 girls aged 13 months to 11 yrs, of which 16 (44%) had positive family history. Serum IgE levels were elevated in 20 (55%) of the cases and 33% of controls with peak values of 4877 and 627 IU/ml, respectively. No statistically significant correlation was observed between childhood asthma and HLA class I antigens, however, a statistically significant correlation was observed between serum IgE levels and asthma, which was elevated in cases, as compared to normal population. Serum IgE levels did not show a linear trend, in that a direct correlation with the severity of disease was not observed.
