Abstract

Introduction

Dalbavancin (DBV), a novel lipoglycopeptide with activity against Gram-positive bacterial infections, is approved for the treatment of acute bacterial skin and skin structure infections. It has linear dose-related pharmacokinetics allowing a prolonged interval between doses. It would be a good option for the treatment of patients with Gram-positive cardiovascular infections.

Material and methods

Retrospective analysis of patients with cardiovascular infection (bacteremia, implantable electronic device infection and infective endocarditis [IE]) treated with DBV at Hospital Clínico San Carlos (Madrid) for 7 years (2016-2022). Patients were divided into 2 study groups: 1) IE, and 2) bacteremia. Epidemiological, clinical, microbiological and therapeutic data were analyzed.

Results

A total of 25 patients were treated with DBV for cardiovascular infection. IE was the most common indication (68%), followed by bacteremia (32%) with male predominance in both groups (64 vs. 62%) and median age of 67,7 and 57,5 years, respectively. Hundred percent of blood cultures were positive to Gram-positive microorganisms (Staphylococcus spp., Streptococcus spp. or Enterococcus spp.) in both study groups. Previously to DBV, all patients received other antibiotic therapy, both in the group of IE (median: 80 days) as in bacteremia (14,8 days). The main reason for the administration of DBV was to continue intravenous antimicrobial therapy outside the hospital in both the EI group (n = 15) and the bacteremia group (n = 8). DBV was used as consolidation therapy in a once- or twice-weekly regimen. Microbiological and clinical successes were reached in 84% of cases (n = 21), 76,4% in IE group and 100% in bacteremia group. No patient documented adverse effects during long-term DBV treatment.

Conclusion

DBV is an effective and safety treatment as consolidation antibiotic therapy in IE and bacteremia produced by Gram-positive microorganisms.

期刊介绍： Hoy está universalmente reconocida la renovada y creciente importancia de la patología infecciosa: aparición de nuevos agentes patógenos, de cepas resistentes, de procesos con expresión clínica hasta ahora desconocida, de cuadros de una gran complejidad. Paralelamente, la Microbiología y la Infectología Clínicas han experimentado un gran desarrollo como respuesta al reto planteado por la actual patología infecciosa. Enfermedades Infecciosas y Microbiología Clínica es la Publicación Oficial de la Sociedad Española SEIMC. Cumple con la garantía científica de esta Sociedad, la doble función de difundir trabajos de investigación, tanto clínicos como microbiológicos, referidos a la patología infecciosa, y contribuye a la formación continuada de los interesados en aquella patología mediante artículos orientados a ese fin y elaborados por autores de la mayor calificación invitados por la revista.
