Article information

Se revisan 12 casos de bacteriemia por Aeromonas spp. en pacientes adultos ocurridos en nuestro centro en un período de 6 años. Tres de los casos correspondían a pacientes con enfermedad hematológica y cuatro presentaban una neoplasia sólida. En 7 enfermos el origen de la infección fue extrahospitalaria y en los 5 restantes fueron consideradas como infecciones adquiridas en el hospital. En 7 pacientes encontramos posibles puertas de entrada. La presentación clínica habitual fue como síndrome febril en todos los casos y sólo en dos pacientes cursó como un shock séptico fulminante. La especie sólo se determinó en cuatro casos 2 A. hydrophila, 1 A. cavilae. 1 A. veronil). La mayoría de las cepas aisladas fueron sensibles a los aminoglucósidos, cotrimoxazol, fosfomicina y quinolonas y resistentes a amplicilina. Fallecieron 3 pacientes (25%) a consecuencia de la infección. La bacteriemia por Aeromonas spp. representó el 0,12% de los hemocultivos en nuestro hospital y acontece en pacientes inmunodeprimidos, si bien puede describirse en personas previamente sanas.

Twelve cases of Aeromonas spp. bacteremia are here reviewed in adult patients ocurred at our institution during a 6-year period. Three cases corresponded to patients with hematological disease and four had a solid neoplasm. The source of infection in seven patients was extra-nosocomial; infections in the five remaining patients were considered to be acquired in the hospital. In seven patients, potential portals of entry were found. The usual clinical presentation was febrile syndrome in all cases and only in two patients did the clinical picture evolve to fulminant septic shock. Speciation of microorganisms was determined in only four cases: 2 A. hydrophilia, 1 A. caviae, and 1 A. veronii. Most isolates were susceptible to aminoglycosides, cotrimozazol, phosphomycin, and quinolonos, and resistant to ampicillin. Three patients (25%) died as a result of the infection. Aeromonas spp. bacteremia represented 0.12% of blood cultures in our hospital and occurs in immunosuppressed patients although it may be reported in previously healthy individuals.
