NCT06432777

Brief Summary

Some rare cases of recurrent Campylobacter bacteraemia (RCB) exist with relapses months to years after an effective treatment and a negativation of all bacterial samples. As of today, only around 20 cases have been described in the international literature for the last 30 years. The cases are likely highly underreported. No study describes those recurrent Campylobacter bacteraemias at the scale of a country. The aim of this multicentre, nationwide, retrospective study is to describe their precise epidemiology in France for the last 25 years, the immune profile of the patients, the specificities of the bacteria involved, the treatments received and the evolution of these infections. The perspective is to propose a standardization of the medical care of those patients mainly by describing the effective treatments and the explorations of the immune system which should be considered.
