Is hLA-DR strongly associated with Vogt-Koyanagi-Harada disease in Mexican Mestizo patients?
The strong association found with HLA-DR4 and the slight DR1 increase shown in Mexican patients with VKH suggest that a common shared sequence present in the third hypervariable region of DRB1 genes is relevant for the expression of the disease. The stronger association with DR4 than the one with DQ8 suggests that the DR locus carries the primary susceptibility genes involved in the pathogenesis of VKH.
In conclusion, the results of this small pilot study indicate that Polish first-contact doctors have an inadequate prescription behaviour in cases with upper respiratory tract infections. Our results underline the need for courses in pharmacotherapy within the postgraduate education course in family medicine recently introduced in Poland.
