In a group of 19 rheumatoid arthritis (RA) patients with normal renal function, serum levels of aluminium (A1S) were monitored during treatment with drugs containing this metal (Al).
The A1S levels during treatment were significantly higher (0.005>p>0.01) than those before treatment, i.e. 19.4 (SEM 2.3)µg/1 and 12.3 (1.7), respectively. This increase in A1S was significantly (0.025>p>0.05) correlated with the pretreatment serum creatinine level (mean value for the whole group 80.5 (SEM 4.7) mol/1) but showed no correlation with the predicted creatinine clearance. Although the increase in A1S during therapy with Al containing drugs is not dramatic in RA patients with normal renal function, the rheumatologist should be aware of the risk of increased A1S concentration in RA patients, especially those with impaired renal function.
