Urinary copper excretion in rheumatoid arthritis.

The pattern of urinary copper excretion in relation to urine osmolality (as shown by series of aliquots of urine) was studied in rheumatoid patients and in control groups. Rheumatoid patients showed an abnormal copper excretion pattern compared with nonrheumatoid subjects. This was not a direct function of the raised serum copper in rheumatoid disease. Measurements based on 24-hour series of aliquots of urine (as distinct from total pooled 24-hour collections) have been shown to be a useful and sensitive method for studying copper excretion patterns.

Synthetic D(-)penicillamine in rheumatoid arthritis. Double-blind controlled study of a high and low dosage regimen.

Doses of 600 mg and 1200 mg of D(-)penicillamine daily were superior to a standard regimen of therapy in rheumatoid arthritis. The higher dose did not produce significantly greater therapeutic benefit in the group of patients so treated, although individual patients sometimes improved more. The frequency of rashes, blood dyscrasias, and withdrawals from the trial increased withe dosage. It is concluded that D(-)penicillamine is a useful treatment that the daily dose should be as low as possible, and that it should be increased at infrequent intervals only, with due regard to the likelihood of further improvement in relation to an increased risk of adverse reactions.

Effect of clofibrate on blood viscosity in intermittent claudication.

Sixty-two patients with intermittent claudication associated with peripheral arterial diseases were treated with clofibrate, 2 g daily, for a minimum of six months. Progress was compared with that in a similar pretreatment period and also with that of a matched untreated control group of 27 patients. The most striking effect of clofibrate was a steep and sustained fall in whole-blood viscosity measured over a wide range of shear rates. This was associated with a significant fall in abnormally raised initial plasma-fibrinogen levels. An increased proportion of patients on treatment showed evidence of clinical improvement. Clofibrate had no effect on the susceptibility of red blood cells to autoxidation but it led to a significant shift in the red cell fatty acid pattern.

Clinical, haemodynamic, rheological, and biochemical findings in 126 patients with intermittent claudication.

Increased blood viscosity has been shown to be an important factor in reducing blood flow in a review and analysis of the history, clinical findings, and haemodynamic, rheological, radiological, and biochemical measurements in 126 patients with intermittent claudication. In some patients increased viscosity seemed to be the determining cause of claudication. A raised plasma fibrinogen was the most common single biochemical abnormality. The results of conventional serum lipid and lipoprotein estimations were abnormal in the series as a whole but did not correlate with clinical findings or flow measurements at individual patient level. There was, however, a significant correlation between some clinical findings and the susceptibility of the red cells to autoxidation.

Prognostic significance of rheological and biochemical findings in patients with intermittent claudication.

To assess the prognostic significance of clinical and laboratory findings in intermittent claudication a group of 62 untreated patients was followed up in detail for periods of from one to three years. There was a significant correlation between progressive deterioration of the peripheral circulatory disturbance and the initial blood viscosity, the plasma fibrinogen level, and the susceptibility of red cell lipids to autoxidation.
