Effect of pentoxifylline on hepcidin and iron profile in hemodialysis patients: A randomized, double-blind, placebo-controlled clinical trial.

Background: Hemodialysis (HD) patients often have elevated levels of hepcidin hormone, which is a key regulator of systemic iron homeostasis. While pentoxifylline (PTX) has been demonstrated to have anti-inflammatory properties, it is unclear if these effects would also have an inhibitory effect on hepcidin. This study aimed to examine the potential role of PTX on hepcidin and its consequent effects on iron profile and anemia in HD patients.
