ABSTRACT
Objectives. To evaluate nephrotoxicity development in patients treated with vancomycin (VAN) and daptomycin (DAP) for proven severe Gram-positive infections in daily practice. Patients and methods. A practice-based, observational, retrospective study (eight Spanish hospitals) was performed including patients ≥18 years with a baseline glomerular filtration rate (GFR)>30 mL/min and/or serum creatinine level<2 mg/dL treated with DAP or VAN for >48h. Nephrotoxicity was considered as a decrease in baseline GRF to <50 mL/min or decrease of >10 mL/min from a baseline GRF<50 mL/min. Multivariate analyses were performed to determine factors associated with 1) treatment selection, 2) nephrotoxicity development, and 3) nephrotoxicity development within each antibiotic group. Results. A total of 133 patients (62 treated with DAP, 71 with VAN) were included. Twenty-one (15.8%) developed nephrotoxicity: 4/62 (6.3%) patients with DAP and 17/71 (23.3%) with VAN (p=0.006). No differences in concomitant administration of aminoglycosides or other potential nephrotoxic drugs were found between groups. Factors associated with DAP treatment were diabetes mellitus with organ lesion (OR=7.81, 95%CI:1.39-4.35) and basal creatinine ≥0.9 mg/dL (OR=2.53, 95%CI:1.15-4.35). Factors associated with VAN treatment were stroke (OR=7.22, 95%CI:1.50-34.67), acute myocardial infarction (OR=6.59, 95%CI:1.51-28.69) and primary bacteremia (OR=5.18, 95%CI:1.03-25.99). Factors associated with nephrotoxicity (R2=0.142; p=0.001) were creatinine clearance<80 mL/min (OR=9.22, 95%CI:1.98-30.93) and VAN treatment (OR=6.07, 95%CI:1.86-19.93). Factors associated with nephrotoxicity within patients treated with VAN (R2=0.232; p=0.018) were congestive heart failure (OR=4.35, 95%CI:1.23-15.37), endocarditis (OR=7.63, 95%CI:1.02-57.31) and basal creatinine clearance<80 mL/min (OR=7.73, 95%CI:1.20-49.71). Conclusions. Nephrotoxicity with VAN was significantly higher than with DAP despite poorer basal renal status in the DAP group
Objectivos: Evaluar el desarrollo de nefrotoxicidad en la práctica clínica diaria en pacientes con infecciones graves probadas por grampositivos, tratados con vancomicina (VAN) y daptomicina (DAP). Pacientes y métodos: Se diseñó un estudio observacional retrospectivo, basado en la práctica clínica diaria (ocho hospitales españoles), en el que se incluyeron pacientes ≥ 18 años con una tasa basal de filtrado glomerular (GFR) > 30 mL/min y/o una creatinina sérica < 2 mg/dl para los pacientes tratados con DAP o vancomicina durante > 48 horas. La nefrotoxicidad fue considerada como una disminución del GRF basal a < 50 mL/min o una disminución de > 10 mL/min desde un GRF basal de < 50 ml/min. Se diseñaron análisis multivariantes para determinar los factores asociados con: 1) la selección del tratamiento, 2) el desarrollo de nefrotoxicidad y 3) el desarrollo de nefrotoxicidad con cada antibiótico. Resultados: Se incluyeron 133 pacientes (62 tratados con DAP, 71 con vancomicina). Veintiuno (15,8%) desarrollaron nefrotoxicidad: 4/62 (6,3%) pacientes con DAP y 17/71 (23,3%) con VAN (p=0,006). No se encontraron diferencias entre los grupos en la administración concomitante de aminoglucósidos u otros fármacos potencialmente nefrotóxicos. Los factores asociados con el tratamiento con DAP fueron diabetes mellitus con lesión orgánica (OR=7,81; IC95%:1,39-4,35) y una creatinina basal ≥0,9 mg/dL (OR=2,53; IC95%:1,15-4,35). Los factores asociados con tratamiento con VAN fueron ictus (OR=7,22; IC95%:1,50-34,67), infarto agudo de miocardio (OR=6,59; IC95%:1,51-28,69) y bacteriemia primaria (OR=5,18, IC95%:1,03-25,99). Los factores asociados con nefrotoxicidad (R2=0,142; p=0,001) fueron aclaramiento de creatinina <80 mL/min (OR=9,22; IC95%:1,98-30,93) y tratamiento con VAN (OR=6,07; IC95%:1,86-19,93). Los factores asociados con nefrotoxicidad en los pacientes tratados con VAN (R2=0,232; p=0,018) fueron insuficiencia cardíaca congestiva (OR=4.35; IC95%:1,23-15,37), endocarditis (OR=7,63; IC95%:1,02-57,31) y una creatinina basal <80 mL/min (OR=7,73; IC95%:1,20-49,71). Conclusiones: La nefrotoxicidad con VAN fue significativamente más alta que la de DAP a pesar del pobre status basal renal del grupo de DAP

Interventricular septum rupture following blunt chest trauma is a rare cardiac injury that sometimes is difficult to diagnose. It has a high mortality rate, especially when in cases of hemodynamic instability requiring early surgical repair. We report the case of an 18-year old man who suffered blunt thoracoabdominal trauma and hemorrhagic shock who required emergency abdominal surgery on three occasions. He was diagnosed of traumatic rupture of interventricular septum that had not been detected in the initial echocardiography, but was suspected after the right heart catheterism. Urgent cardiac surgery was performed 72 hours later because of hemodynamic instability.

La rotura del septo interventricular por traumatismo cerrado de tórax es una rara lesión cardíaca cuyo diagnóstico puede ser pasado por alto y que muestra una elevada mortalidad en los casos con inestabilidad hemodinámica que requieren cirugía correctora precoz. Presentamos el caso de un joven de 18 años con traumatismo toracoabdominal cerrado y shock hemorrágico que precisó cirugía abdominal urgente en tres ocasiones. Fue diagnosticado de rotura traumática del septo interventricular no detectada en el ecocardiograma inicial, que se sospechó tras cateterismo cardíaco derecho y se intervino quirúrgicamente de urgencia a las 72 h de su ingreso
