Abstract
Introduction

People migrating to the Canary Islands by sea frequently suffer from potentially severe skin and soft tissue infections (SSTIs) for which optimal empirical antibiotic therapy is not well defined.

Methods

This descriptive retrospective observational study assess a case series of newly arrived maritime migrants to the Canary Islands who were diagnosed with clinical and microbiological SSTIs and admitted to the Nuestra Señora de La Candelaria Hospital in Tenerife between January 2020 and December 2023. Clinical data, bacterial species, resistance profiles, and choice of empirical treatments were analysed.

Results

A total of 23 patients with SSTIs were analysed, with 21 (91.3%) presenting lesions in the gluteal-sacral region. Thirty-seven community-acquired pathogenic microorganisms were isolated, including seven from blood cultures. The isolated bacteria included Staphylococcus aureus (n = 12/37, 32.4%), Enterobacterales (n = 9/37, 24.3%), marine bacteria (n = 7/37, 18.9%), non-fermenting gram-negative bacteria (n = 6/37, 16.2%), and other gram-positive cocci (n = 2/37, 5.4%). Treatment was inappropriate in 9 of 23 cases (39.1%), with amoxicillin/clavulanic acid being the most prescribed antibiotic (n = 11/23, 47.8%).

Conclusions

The study suggests that, in addition to the importance of bacteria such as S. aureus, consideration should be given to Enterobacterales, marine bacteria, and gram-negative non-fermenting bacteria (such as Pseudomonas aeruginosa) when choosing empirical antibiotic therapy for SSTIs in maritime migrants.

Resumen
Introducción

Las personas que migran a Canarias por vía marítima padecen con frecuencia infecciones de piel y partes blandas (IPPB) que son potencialmente graves y cuya antibioterapia empírica óptima no está claramente definida.

Métodos

Estudio observacional retrospectivo descriptivo de una serie de casos con diagnósticos clínicos y microbiológicos de IPPB en pacientes migrantes recién llegados a Canarias por vía marítima, ingresados en el Complejo Hospitalario Nuestra Señora de La Candelaria de Tenerife entre enero de 2020 y diciembre de 2023. El estudio analiza los datos clínicos más relevantes, las especies bacterianas aisladas, los perfiles de resistencia y los tratamientos empíricos seleccionados.

Resultados

Se analizaron 23 pacientes con IPPB, de los cuales 21 (91,3%) presentaban lesiones en la región glútea-sacra. Se aislaron 37 microorganismos patógenos adquiridos en la comunidad, incluidos 7 de hemocultivos. Las bacterias aisladas fueron Staphylococcus aureus (n = 12/37, 32,4%), Enterobacterales (n = 9/37, 24,3%), bacterias marinas (n = 7/37, 18,9%), bacterias gramnegativas no fermentadoras (n = 6/37, 16,2%) y otros cocos grampositivos (n = 2/37, 5,4%); El tratamiento fue inadecuado en 9 casos de 23 (39,1%) y el antibiótico más prescrito fue amoxicilina/ácido clavulánico (n = 11/23, 47,8%).

Conclusiones

El estudio sugiere que, junto a la importancia de bacterias como S. aureus, se debe tener en cuenta a los Enterobacterales, las bacterias marinas y las bacterias no fermentadoras gramnegativas (como Pseudomonas aeruginosa), a la hora de elegir el tratamiento antibiótico empírico para las IPPB en personas migrantes llegadas por vía marítima.
