Objectives: To determine the frequency of different HLAantigens in patients with plaque psoriasis in the Omani Arab
population.
Methods: Fifty four Omani patients clinically diagnosed with
plaque psoriasis attending the dermatology outpatient clinic in
Al-Nahdah Hospital (the tertiary dermatology centre in Oman)
were selected for HLA studies.
Results: HLA-B52 was present in 20.4% of patients 11/54 and
in 5% of controls without psoriasis 5/100. For the association
p was <0.004 and the relative risk (RR) was 4.86.
Conclusion:Psoriasis does not appear to be associated universally
with the same HLA antigens. The association of HLA-B52 with
plaque psoriasis in Omani patients compares with the HLACw6, -Bw57 and -DR7 preponderance in most other ethnic
groups.
