Rheumatological complaints accounted for 10·6 per cent of new presentations in this general-practice survey. Spinal problems formed almost half of this total and led to a greater degree of disability than other locomotor system disorders. Active participation in the treatment of pain by the practitioner's use of manipulation and injection technique...

The effect of immune complexes (IC) isolated from systemic lupus erythematosus (SLE) sera with polyethylene glycol and gel filtration on the chemotaxis and Fc receptor function of healthy monocytes was examined. Even at a low protein concentration (1 microgram/ml = 1 mg/l) ICs inhibit monocyte chemotaxis. ICs from patients with SLE nephritis are mo...
Tophi are rarely observed in patients without a prior history of gouty arthritis. We describe four patients whose initial manifestation of gout was tophaceous deposition in an unusual location, the finger pad. None of these patients had a history of acute gouty arthritis and none had tophi elsewhere. All four patients were postmenopausal women with...
Aortitis as a feature of rheumatoid arthritis is considered rare. We have, however, identified 10 patients with aortitis from among 188 consecutive autopsy cases of rheumatoid arthritis. There were 5 men and 5 women with a mean duration of rheumatoid arthritis of 9.6 years. Nine were rheumatoid factor positive and had associated nodules. In additio...
In this study, fibronectin synergized with anti-CD3 antibody to promote CD4 cell proliferation in a serum-free culture system. The cell-adhesive domain plus additional regions of the fibronectin molecule are involved in this synergy. Anti4B4(CDw29) antibody blocked the activation of CD4 cells in this system. Furthermore, it is the VLA-5 protein wit...
beta-glucan receptors, with ligand specificity for yeast and fungal carbohydrate polymers, have been studied as phagocytic receptors of human monocytes. To characterize their structure, binding studies were carried out with human U937 cells and a rabbit IgG anti-Id that recognizes epitopes on monocyte beta-glucan receptors. Unstimulated U937 cells ...
A cofactor that selectively opsonizes particulate activators of the human alternative complement pathway and enhances their phagocytosis by human monocytes was identified in synovial fluids of patients with rheumatoid arthritis. The active material was present in fluids treated with protease inhibitors, was heat stable, and was unaffected by incuba...
Using an ELISA, anti-endothelial cell antibodies (AECA) have been found in sera obtained at the time of renal biopsy in 46 out of 57 patients (81%) with systemic lupus erythematosus (SLE) and nephritis (mean binding index (BI)=84%±52.8) compared with 22 out of 50 SLE patients (44%) without nephritis (mean BI=45%±35.9). Seventy normal human sera had...
