Poststreptococcal sequelae, especially acute rheumatic fever/rheumatic heart disease continues to occur in significant proportions in many parts of the world, especially in less developed countries. An important factor in the study of rheumatic heart disease is the human genetic susceptibility to the disease. The aim of the present study was to detect the most prevalent HLA class I and class II types associated with risk of rheumatic heart disease in Egyptian children. Our study was performed on 100 patients with rheumatic valvular heart diseases and 71 control subjects. Patients were recruited from the Heart Institute, Embaba, Egypt. HLA typing for HLA class I was performed by serotyping and HLDR allele genotyping was performed using INNO-LiPA kits. In the study of HLA class I, there was a statistically significant increase in the B5 allele (P = 0.03; odds ratio, 3.46 [1.12–10.72]) in patients compared to controls, while B49 and B52 alleles (P = 0.004 and P = 0.02) were found in controls only. There was a statistically significant increase in HLA DR* 04-02, 3.46 (1.12–10.72) and HLA DR *10-0101 5.75 (1.27–25.98) in patients. Meanwhile HLA DR*1309120 was found only in controls (P = 0.02). Our study provides further information on the genetic predisposition for rheumatic valvular disease and the protective genotypes in rheumatic heart disease. Further insight into the molecular mechanisms of the disease will be a useful tool for predicting clinical outcome in those patients and, thus, potentially offer new means and approaches to treatment and prophylaxis, including a potential vaccine.
