ABSTRACT
Objetivo Corynebacterium striatum (C. striatum) es un microorganismo emergente en la infección de pie diabético poco estudiado. El objetivo es evaluar los factores de riesgo (FR) relacionados con osteomielitis por C. striatum en paciente con pie diabético. Métodos Estudio casos-controles en la Unidad de Pie Diabético entre 2015 y 2021. Un número de 44 pacientes con osteomielitis por C. striatum (casos) y 44 con osteomielitis por microorganismo distinto (controles) fueron incluidos. Resultados Enfermedad arterial periférica (odds ratio [OR]: 2,8, p = 0,037), fibrilación auricular (OR: 3,7, p = 0,034), pie diabético isquémico (OR: 3,3, p = 0,020) y antibioterapia previa prolongada más de 14 días (OR: 3,4, p = 0,012) fueron FR para la osteomielitis por C. striatum. En el análisis multivariado la antibioterapia más de 14 días fue el único FR independiente (OR: 3,46; p = 0,017) para osteomielitis por C. striatum. Conclusiones La antibioterapia previa recibida durante más de 14 días es un FR independiente y estadísticamente significativo de osteomielitis por C. striatum en pacientes con pie diabético (AU)
Objective Corynebacterium striatum (CS) is an emerging micro-organism in diabetic foot infection for which there are currently few studies. The objective was to analyze the risk factors (RF) related to CS osteomyelitis in patients with diabetic foot. Methods A casecontrol study was conducted in the Diabetic Foot Unit between 2015 and 2021. Forty-four patients with osteomyelitis due to CS (cases) and 44 patients with osteomyelitis due a different micro-organism (controls) were included. Results Peripheral artery disease (OR: 2.8, p = 0.037), atrial fibrillation (OR: 3.7, p = 0.034), ischemic diabetic foot (OR: 3.3, p = 0.020) and previous prolonged antibiotic therapy more than 14 days (OR: 3.4, p = 0.012) were identified as RF for osteomyelitis due to CS. When performing the multivariate analysis antibiotic therapy >14 days was independent RF (OR: 3.46; p = 0.017). Conclusions Previous antibiotic therapy received more than 14 days is an independent and statistically significant RF for CS osteomyelitis in patients with diabetic foot (AU)
