摘要：

Tumor necrosis factor alpha (TNF-alpha) blockade is an effective treatment for patients with TNF-alpha-dependent chronic inflammatory diseases, such as rheumatoid arthritis, Crohn's disease, and psoriasis. TNF-alpha kinoid, a heterocomplex of human TNF-alpha and keyhole limpet hemocyanin (KLH) (TNF-K), is an active immunotherapy targeting TNF-alpha. Since the TNF-K approach is an active immunization, and patients receiving this therapy also receive immunosuppressant treatment, we evaluated the effect of some immunosuppressive drugs on the generation of anti-TNF-alpha antibodies produced during TNF-K treatment. BALB/c mice were injected intramuscularly with TNF-K in ISA 51 adjuvant. Mice were also injected intraperitoneally with one of the following: phosphate-buffered saline, cyclophosphamide, methylprednisolone, or methotrexate. Anti-TNF-alpha and anti-KLH antibody levels were assessed by enzyme-linked immunosorbent assay and the anti-TNF-alpha neutralizing capacity of sera by L929 bioassay. Our results showed that current treatments used in rheumatoid arthritis, such as methylprednisolone and methotrexate, do not significantly alter anti-TNF-alpha antibody production after TNF-K immunization. In contrast, the administration of cyclophosphamide (200 mg/kg) after immunization significantly reduced anti-TNF-alpha antibody titers and their neutralizing capacity.
