Abstract: | Pentoxifylline (POF) has been shown to have anti-inflammatory and immunomodulatory effects. including suppression of TNF-alpha production by activated macrophages, Th-1 response of T cells, and fibroblasts' proliferation and metalloproteinase production. Pentoxifylline was also reported to possess therapeutic properties in 50% of severe refractory RA in an open study. We experienced a 64 year-old man with seronegative RA, stage 2, class 3. He showed 23 swollen joints, 32 painful joints, ADL score 37/40, and ESR 135 mm/h. All these parameters were dramatically improved 3 weeks after administration of POF 300 mg/d and prednisolone 5 mg/d. Discontinuation of POF resulted in rapid exacerbation of RA. POF was restarted and the patient showed complete recovery from arthritis with normalization of ESR within 3 months and was maintained a complete remission for another 1 year. This case further supports a potential antirheumatic effect of POF on some patients with RA. |
