title: [HL-A and psoriatic rheumatism].
abstract: The HL-A groups, including the characteristics of 25 antigens, were measured in 61 patients suffering from psoriatic rheumatism, among them 9 with central forms (pelvispondylitis) and 52 with peripheral forms (polyarthritis with or without sacroileitis). Analysis of the results and comparison of them with those of other workers led to the following conclusions: 1) Central psoriatic rheumatism is associated mainly with W27 and Da31, less closely with HL-A13, and slightly or not at all with W17. 2) Peripheral psoriatic rheumatism has the same relationship with the HL-A system as has psoriasis without anthropathy. It is associated mainly with W17, less closely with Da31 and HL-A13, and slightly or not at all with W27. 3) By their relationship to the HL-A system, the two varieties of psoriatic rheumatism may be clearly distinguished from one another and from other inflammatory rheumatisms. The HL-A groupings are of considerable value in the differential diagnosis between central psoriatic rheumatism, peripheral psoriatic rheumatism, ankylosing spondylarthritis, the Fiessinger-Leroy-Reiter syndrome and rheumatoid arthritis.
