C. Marguerie et al., ANTI-PL-4 IN PATIENTS WITH SYSTEMIC LUPUS-ERYTHEMATOSUS WITH SEVERE RENAL AND HEMATOLOGICAL DISEASE, Quarterly Journal of Medicine, 90(5), 1997, pp. 347-352
Anti-FL 4 is an autoantibody which binds to a 150 kDa polypeptide and
is found in approximately 1% of SLE sera. The clinical and laboratory
features of 16 patients who have had anti-FL 4 detected in their serum
are presented. Anti-FL 4 is highly specific for SLE (100%) and identi
fies a population of patients who typically develop severe renal (75 %
) and haematological disease (100%).
