- The purpose was to investigate if antigenic fragments of aggrecan and cartilage oligomeric matrix protein (COMP) are detectable by enzyme-linked immunosorbent assay in lavage fluids from the temporomandibular joint (TMJ) and to examine if the relative content of these cartilage markers changes during development of osteoarthrosis (OA) after diskectomy. Lavage fluid was obtained at surgery and 6 months postoperatively in 13 patients. Computed tomography or magnetic resonance imaging was without evidence of hard-tissue changes prior to surgery in all patients. In 9 of the patients, sufficient material for analysis was obtained at both examinations. Aggrecan and COMP were detectable in all but 2 fluids, in which the COMP levels were below detection limit. The aggrecan/COMP ratio increased in all 9 patients during the 6-month period, indicating increased release of aggrecan relative to COMP fragments. The changed aggrecan/COMP ratio possibly reflects increased cartilage turnover during development of OA. Changes compatible with OA were present on computed tomography in all cases at the 6-month follow-up. This study shows that the lavage procedure is feasible for obtaining synovial fluid from the TMJ for immunochemical analyses of tissue-derived macromolecules.

- Congenital dyserythropoietic anaemia type III (CDA III) is a rare disease inherited in an autosomal dominant way and characterized by mild to moderate haemolytic anaemia. Most patients are adapted to their disease and have no or few complaints. Bone marrow examination shows a characteristic picture with erythroid hyperplasia and multinucleate erythroblasts. 20% of patients in a Swedish family affected with the CDA III condition have monoclonal gammopathy or multiple myeloma. By linkage and recombination analysis in the same family, the gene linked to the CDA III condition (CDAN3) has been located to chromosome 15q22. In this paper we report the observation of visual disturbances with macular degeneration and angioid streaks in six patients with CDA III and discuss the apparent association between CDA III, angioid streaks and monoclonal gammopathy. We suggest that this triad forms a previously unreported syndrome.
