In today’s edition of The Lancet [Friday 7 February], doctors report the case of a patient with severe heart failure, who in May 2012 was referred to the Marburg University clinic in Germany. Medical examinations ruled out coronary artery disease, a common cause of heart failure, but the medics working on the case noticed some striking similarities between the patient’s symptoms and those of a fictional patient in the TV Series House, ultimately diagnosed by lead character Gregory House, M.D. (played by British actor Hugh Laurie) as cobalt poisoning caused by debris from a metal hip replacement.
The medical history of the real-life patient showed that in November 2010, he had undergone a metal-on-plastic hip replacement to replace a broken ceramic-on-ceramic hip prosthesis. Half a year later the patient suffered from various symptoms, such as hypothyroidism, oesophagitis, fever of unknown origin, increasing deafness and loss of sight, and finally severe heart failure.
For more than a year, and after numerous hospital visits, the true cause of all these symptoms remained unclear. Finally, the patient was referred to Marburg where the doctors concluded that, like Dr House’s fictional patient, their patient was suffering from Cobalt poisoning. The patient was referred back to his former orthopaedic clinic, where he received a new ceramic hip prosthesis, and thereafter his heart function improved and he experienced no new episodes of fever or acid reflux.
