Abstract:
Recent publications were compared and analysed in addition to novel surveillance data to assess the hypothesis that fluoroquinolone-resistant Campylobacter infections are causing more severe disease than susceptible infections. The available data did not support this hypothesis. There was no significant difference in duration of disease between susceptible and resistant infections. However, both for resistant and susceptible infections, disease symptoms were prolonged by on average 1-2 days for Campylobacter cases acquired during foreign travel. Nevertheless, the likelihood and duration of hospitalisation were not increased for cases related to foreign travel. These observations were confirmed by a new analysis of almost 11,000 cases. We conclude that fluoroquinolone-resistant Campylobacter infections are not more severe than susceptible infections.
Insights
Fluoroquinolone-resistant Campylobacter infections do not cause more severe disease than susceptible infections. Foreign travel may prolong symptoms for both types of Campylobacter infections, but does not increase hospitalization.
Area of Science:
- Infectious Diseases
- Antimicrobial Resistance
- Public Health
Background:
- Campylobacter infections are a common cause of bacterial gastroenteritis.
- The rise of fluoroquinolone resistance in Campylobacter poses a public health concern.
- Previous studies have suggested fluoroquinolone-resistant Campylobacter may cause more severe illness.
Purpose of the Study:
- To evaluate whether fluoroquinolone-resistant Campylobacter infections lead to more severe disease compared to susceptible infections.
- To analyze the impact of foreign travel on Campylobacter infection severity.
Main Methods:
- Comparative analysis of recent publications and novel surveillance data.
- Statistical analysis of disease duration, hospitalization likelihood, and duration.
- Inclusion of a large dataset comprising nearly 11,000 Campylobacter cases.
Main Results:
- No significant difference in disease duration was found between fluoroquinolone-resistant and susceptible Campylobacter infections.
- Campylobacter infections acquired during foreign travel showed a 1-2 day prolongation of symptoms for both resistant and susceptible cases.
- Hospitalization likelihood and duration were not significantly increased for cases associated with foreign travel.
Conclusions:
- Fluoroquinolone resistance in Campylobacter does not appear to increase disease severity.
- Foreign travel is associated with prolonged symptoms but not increased hospitalization for Campylobacter infections.
- Surveillance data and publication analysis confirm the lack of increased severity in resistant Campylobacter infections.
