   <dc:description>SIR, In the report by Helin et al in the Annals' the authors&#xd;
suggest that rheumatoid factor (RF) protects against&#xd;
nephropathy in patients with systemic lupus erythematosus&#xd;
(SLE).&#xd;
We have reviewed our series of 78 patients with SLE&#xd;
fulfilling the criteria of the above report for evaluating&#xd;
nephropathy and assaying RF. The Waaler-Rose sensitised&#xd;
sheep cell agglutination test was used to measure RF, with&#xd;
titres equal or greater than 1/64 considered positive. Both&#xd;
groups with and without renal disease were comparable for&#xd;
age and sex. A renal biopsy was performed in 38 out of 40&#xd;
patients with nephropathy...</dc:description>
