The objective of the present study was to analyse if there are links also between HLA-DRB1* alleles and HS, since it is a specific phenotype of sarcoidosis.1000 patients with sarcoidosis, out of which 83 had symptoms associated with HS, were included in the study together with a group of 2000 healthy individuals from the same population, matched for gender and age. HLA-DRB1* allelic groups were determined for all individuals, and comparisons were made between different disease subgroups and between patients and healthy controls.We found that the HLA-DRB1*04 allele was overrepresented in patients with symptoms associated with HS. Eighty-three (8.3%) of all patients had one or more of the symptoms and forty-six (55%) of them were HLA-DRB1*04 positive. Forty-four (55%) of the patients with ocular sarcoidosis, i.e. the most common symptom associated with HS, were HLA-DRB1*04 positive, compared to 35.9% of healthy controls (p=0.0008), and only 26.6% of the whole group of sarcoidosis patients (p<0.0001).HLA-DRB1*04 seems to protect against overall sarcoidosis, but to be a significant risk factor for ocular sarcoidosis as well as for other manifestations associated with HS.
