摘要

Crohn's disease is rare in South African black people and primary sclerosing cholangitis (PSC) is also rare in black patients with IBD, from South Africa. The presence of HLA-B27 is generally associated with seronegative spondylo-arthropathies and correlates with the occurrence of ankylosing spondylitis, recurrent mouth ulcers and uveitis, in patients with IBD. We describe two women with the combination of Crohn's disease, PSC and HLA-B27 from our cohort of the last 5 years of three black patients with Crohn's disease. Crohn's disease, PSC and HLA-B27 respectively, occur rarely in black South Africans and their concurrent presence in two black women suggests a pathogenetic link of HLA-B27 between Crohn's disease and PSC in this population. Female gender might be an additional determinant in this setting.
