SIR, Tumour necrosis factor-
(TNF-
) blocker therapies are widely used in the treatment of chronic inflammatory diseases. However, patients show large heterogeneity in their response to anti-TNF-
therapy. The genotypic background of TNF-
and TNF receptor (TNFR) genes could account for patients resistance to TNF-
blockers [1, 2]. HLA-DR haplotypes have been related with rheumatoid arthritis (RA) susceptibility, severity and course [3], but TNF and TNFR polymorphisms seem to have independent predictive value of patients response to anti-TNF-
therapy [2, 4, 5
