Title: Anti TNFa Treatment for Deep Endometriosis Associated Pain : a Randomised Placebo Controlled Trial.
Brief Summary: Deep endometriosis associated pain is believed to be caused by inflammation. Anti TNFa has been proved to be an effective treatment for other inflammation related conditions as Crohn's disease Endometriosis is associated with an inflammatory response in the pelvis, which is mediated by a number of cytokines including TNF-α. It has therefore been suggested that infliximab, an anti-TNF-α monoclonal antibody, might relieve pain in affected women.
