Summary

  8. Gastrointestinal hemorrhage.
  9. Known human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS)-related illness, or hepatitis B or C.
  10. Patients with autoimmune disorders or history of organ transplantation who require immunosuppressive therapy.
  11. Psychiatric disease that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results.
* Radiofrequency treatment technically not possible (e.g. larger metal implants)
* Cardiac pacemakers/ICD
* Patient not able for supine positioning (e.g. due to pain)
