Hematologist warns against misuse of plasmapheresis

On September 10, 2026, hematologist Sotiris Koumas issued a formal warning regarding the medical use of plasmapheresis outside of established therapeutic indications. Speaking to the Cyprus News Agency (CNA), Koumas emphasized that the procedure carries risks ranging from mild to severe complications and should only be performed in specialized centers. While plasmapheresis is a recognized treatment in fields such as hematology, neurology, and rheumatology, its application outside these protocols remains a point of medical concern.

The public discussion was prompted by reports following the death of Giorgos Mazonakis, with social discourse linking the procedure to anti-aging practices. Dr. Koumas clarified that he is not participating in the specific debate surrounding the death but reaffirmed that the primary medical duty is to avoid causing patient harm. Regarding the domestic situation, the doctor stated he is uncertain about the extent to which such unauthorized practices are occurring in Cyprus, calling for increased oversight by competent authorities.

Public hospitals currently follow strict protocols for plasmapheresis, with outcomes reported to be consistent with international success and failure rates. The expert emphasized the urgent need for regulatory checks to ensure that this medical procedure is not abused for non-therapeutic purposes.
