Antimicrobial resistance in Neisseria gonorrhoeae isolates from foreign-born population in the European Gonococcal Antimicrobial Surveillance Programme.

OBJECTIVES

International spread has contributed substantially to the high prevalence of antimicrobial resistant (AMR) Neisseria gonorrhoeae infections worldwide. We compared the prevalence of AMR gonococcal isolates among native persons to foreign-born (reporting country different from country of birth) persons, and describe the epidemiological and clinical characteristics of foreign-born patients and their associations to AMR.

METHODS

We analysed isolates and patient data reported to the European Gonococcal Antimicrobial Surveillance Programme (Euro-GASP) 2010-2014 (n=9529).

RESULTS

Forty-three per cent of isolates had known country of birth and 17.2% of these were from persons born abroad. Almost 50% of foreign-born were from the WHO European Region (13.1% from non-European Union [EU] and the European Economic Area [EEA] countries). Compared with isolates from natives, isolates from foreign-born had a similar level (p>0.05) of azithromycin resistance (7.5% vs 7.2%), ciprofloxacin resistance (50.0% vs 46.3%) and of decreased susceptibility to ceftriaxone (1.9% vs 2.8%); a lower rate of cefixime resistance (5.7% vs 3.6%, p=0.02), and a higher proportion of isolates producing penicillinase (8.4% vs 11.7%, p=0.02). Among isolates from persons born outside EU/EEA, the level of decreased susceptibility to ceftriaxone was higher (1.8% vs 3.5%, p=0.02), particularly in those from the WHO Eastern Mediterranean Region and non-EU/EEA WHO European countries (1.9% vs 9.6% and 8.7%, respectively, p<0.01). In multivariable analysis, foreign-born patients with AMR isolates were more likely to be from non-EU/EEA WHO European countries (adjusted OR [aOR]: 3.2, 95% CI 1.8 to 5.8), WHO Eastern Mediterranean countries (aOR: 1.8, 95% CI 1.1 to 3.3) and heterosexual males (aOR: 1.8, 95% CI 1.2 to 2.7).

CONCLUSIONS

Importation of AMR strains remains an important threat in the EU/EEA. Research to improve understanding of sexual networks within foreign born and sexual tourism populations could help to inform effective tailor-made interventions. The Euro-GASP demonstrates the public health value of quality-assured surveillance of gonococcal AMR and the need for strengthened AMR surveillance, particularly in the non-EU/EEA WHO European Region.
