Vascular damage and factor-VIII-related antigen in the rheumatic diseases.

Factor-VIII-Related antigen (VIII R:Ag) is known to be produced by the blood vessel wall. Noxious stimuli increase endothelial release of VIII R:Ag. It might be expected that the development of vasculitis would be associated with increased levels of VIII R:Ag. To investigate this, eight different groups of subjects were studied: 25 patients with systemic sclerosis, 19 with systemic lupus erythematosus, 15 with rheumatoid arthritis (RA) plus vasculitis, 19 with systemic vasculitis and 14 with atherosclerosis. These groups were compared to 29 patients with primary Raynaud's disease, 15 with RA without vasculitis and 50 controls. Results showed that where there was evidence of vascular disease, then VIII R:Ag was elevated. VIII R:Ag appeared to be a more specific marker for vascular damage than erythrocyte sedimentation rate or C-reactive protein. Longitudinal studies in 11 patients showed good correlation between progression of vascular disease and VIII R:Ag.

Have the newer NSAIDS contributed to the management of rheumatoid arthritis?

Approximately 30 non-steroidal anti-inflammatory agents are available for the treatment of rheumatoid arthritis. In this study patient acceptability of five such agents (benoxaprofen, fenbufen, feprazone, flurbiprofen, ketoprofen) is compared in groups of 50 patients with rheumatoid arthritis. Less than 40 per cent of patients continued on the prescribed drug for six months. Significantly more patients stopped fenbufen than stopped feprazone, otherwise dropout rates between the groups were similar. The overall efficacy and toxicity of most currently prescribed NSAIDs appear to be similar, and the availability of a surfeit of such agents dilutes clinical experience with any one drug. Despite subsequent events this method failed to differentiate benoxaprofen from the other agents. It would seem likely that this surfeit of similar drugs hinders detection of unusual complications, and impedes satisfactory management of inflammatory rheumatic disorders.

The geometric knee replacement in polyarthritis.

The British Orthopaedic Association assessment questionnaire for knee replacements was adapted to allow comparison of the severity of underlying polyarthritis with the benefits of geometric knee replacement in a retrospective study of 150 knees between six months and six years after operation. Total or partial relief of pain was achieved in 81 per cent of the operation, and changes in mobility occurred in fewer patients. Late sepsis remained a serious complication of nine per cent of the operations and one patient died from septicaemia. Late sepsis was associated with previous synovectomy or osteotomy. Retropatellar pain rarely interfered with the mobility of the patient. There was no association of operations that failed with a high erythrocyte sedimentation rate, a high platelet count, a low haemoglobin level or with a strongly positive rheumatoid factor but pain in the contralateral knee was associated with a diminished functional capacity.
