Investigation follows death of Giorgos Mazonakis at private clinic

The death of Giorgos Mazonakis at a private clinic in Kolonaki, Greece, reported on September 14, 2026, has prompted a major investigation into the medical procedures offered by private practices. The case has specifically centered on the use of plasmapheresis, a procedure that some facilities are reportedly marketing as a treatment for detoxification and anti-aging despite significant clinical risks.

Alexis Rampotas, an academic clinical lecturer at the UCL Cancer Institute, has publicly condemned the application of heavy medical procedures like plasmapheresis for wellness purposes, describing the practice as potentially criminal. Medical experts, including pneumonologist Charis Armeftis, warn that patients are often sold unverified "hope" through expensive, non-standardized treatments. Reports indicate that some clinics administer substances without proper labeling, leaving patients unaware of what is entering their bodies.

In response to these events, medical professionals are calling for urgent, strict oversight and intervention by the Ministry of Health. There is a broad consensus that authorities must conduct rigorous inspections of private medical facilities that advertise experimental or unproven therapies to prevent further casualties and protect public health.
