Methotrexate and Infliximab

One patient’s symptoms were improved with methotrexate and infliximab[1]. However, in another patient with Dercum’s disease, the effect of methotrexate was discreet[2]. The mechanism of action is unclear. Methotrexate has been shown to reduce neuropathic pain caused by peripheral nerve injury in a study on rats [3].

*Case reports are generally considered a type of anecdotal evidence. Given their intrinsic methodological limitations, including lack of statistical sampling, case reports are placed at the foot of the hierarchy of clinical evidence, together with case series.
