  • Title: [Scleroderma and HLA antigens].
    Author: Holzmann H, Sollberg S, Schütz K, Kühnl P.
    Journal: Hautarzt; 1989 Mar; 40(3):134-40. PubMed ID: 2714991.
    Abstract:
    A possible HLA disease association was investigated in 40 patients (38 female, 2 male) with progressive systemic scleroderma (PSS), and 42 patients (32 female, 10 male) with morphea. HLA ABCDR/DQ, glyoxalase and properdin factor B (GLO and BF) phenotypes of patients were compared with 193 healthy controls. Four PSS family studies were performed. The following relative risk (rR) values were determined in PSS: A1 (1.38), A2 (1.39), B8 (1.67), B15 (3.22) and in morphea: A3 (1.43), B7 (1.39), B40 (1.81), BW60 (2.49), DR2 (2.38) and DRW8 (2.55), indicating a relatively weak, HLA-linked genetic predisposition for the manifestation of these dermatological disorders. The HLA "risk" antigens for the two clinically different subtypes of the disease are also different: raised A1/B8 frequencies such as those in our PSS group are related to high (or pathologic) immune response (autoimmune disorders). In contrast, A3 B7 DR2 elevations such as those recorded in our morphea group correlate with low immune response. Following exposition to certain suspected environmental factors (quartz, chemical solvents, drugs, viral fragments), the HLA phenotype may thus predipose some individuals--predominantly women--to different clinical patterns of the disease. HLA typing may thus be useful in clinical differential diagnosis (recent subtyping protocols) and possibly also for determination of the prognosis, i.e. HLA-B8 seems to be related to an acute, inflammatory course of PSS, and HLA-B7/DR2, to rather mild morphea patterns.
