| collagen diseases | Historically, a heterogeneous group of acute and chronic diseases, including rheumatoid arthritis, systemic lupus erythematosus, progressive systemic sclerosis, dermatomyositis, etc. This classification was based on the notion that "collagen" was equivalent to "connective tissue", but with the present recognition of the different types of collagen and the aggregates derived from them as distinct entities, the term "collagen diseases" now pertains exclusively to those inherited conditions in which the primary defect is at the gene level and affects collagen biosynthesis, post-translational modification, or extracellular processing directly. (12 Dec 1998) |
| collagen-vascular diseases | A group of generalised disease's affecting connective tissue and frequently characterised by fibrinoid necrosis or vasculitis; in some collagen disease's, auto-immunization, particularly antinuclear antibodies, has been shown and circulating immune complexes are found. The term is not entirely acceptable because there is no evidence that collagen is primarily involved; "collagen" was once synonymous with "connective tissue" rather than describing a specific fibrinous protein in that tissue. See: connective-tissue diseases. (05 Mar 2000) |
