ABSTRACT
BACKGROUND:
Reunion Island is a French overseas department located in a tropical area, where cystic fibrosis incidence is high. Cystic fibrosis (CF) patients are at risk of developing nontuberculous mycobacteria (NTM) infection. Epidemiologic studies are lacking in Reunion Island.METHODS:
From 2002 to 2015, a retrospective review was performed in university hospitals on Reunion Island. All CF patients having at least 1 positive NTM isolate were included. Clinical, radiologic, and microbiologic data were collected from patient records.RESULTS:
Fifty-one CF patients were included. The overall estimated prevalence of NTM was 26.4% in total CF population and 36.9% in patients over 12 years of age. Mycobacterium abscessus and Mycobacterium avium were the most frequently identified species found in 31 patients (60.8%) and 14 patients (27.4%), respectively. A rare NTM species Mycobacterium simiae was found in 4 patients (7.8%). Twenty-nine patients (56.9%) met the American Thoracic Society (ATS) criteria for infection. They were more likely younger with a low body mass index and more frequently infected by Mycobacterium abscessus (22/29).CONCLUSION:
The overall prevalence of NTM in tropical Reunion Island is 3 times higher than in metropolitan France. A different environmental exposure in a tropical climate or risk factors related to cystic fibrosis or its treatment in Reunion patients could explain it.
