RESUMO

Introducción: La infección no complicada del tracto urinario bajo y la bacteriuria asintomática son causas frecuentes de consulta médica ambulatoria y en el servicio de urgencias en Colombia y el mundo. La falta de pautas y consenso para el manejo, así como la emergencia de resistencia a las múltiples opciones terapéuticas disponibles en los uropatógenos provenientes de la comunidad, hacen necesario elaborar unas recomendaciones que orienten al clínico sobre el abordaje óptimo de estas entidades. Objetivo: Definir un consenso sobre el manejo empírico de la bacteriuria asintomática y la infección del tracto urinario (ITU) bajo en adultos y mujeres embarazadas en Colombia. Metodología: Se lleva a cabo una metodología de consenso con expertos en urología, infectología, medicina interna, ginecología y microbiología basada en la revisión de las referencias bibliográficas disponibles en los términos de búsqueda relacionados, haciendo énfasis en estudios locales. Resultados: Se elaboró un algoritmo de manejo para el tratamiento empírico de la ITU baja no complicada en adultos con antisépticos urinarios como nitrofurantoína y fosfomicina trometamol como primera línea, con recomendaciones terapéuticas específicas para el tratamiento de la bacteriuria asintomática en mujeres embarazadas. Adicionalmente, se formuló un algoritmo de decisión para el procesamiento de cultivos de orina. La recurrencia o recaída frecuente justifica remisión a urología e infectología. Conclusiones: Se generan recomendaciones prácticas de fácil implementación en el diagnóstico y manejo de la ITU bajo en adultos y embarazadas, y de los casos donde es necesario tratar la bacteriuria asintomática, con opciones terapéuticas efectivas y de espectro reducido.


Background: Uncomplicated infection of the lower urinary tract and asymptomatic bacteriuria are frequent causes of visits to outpatient clinics and emergency departments in Colombia and worldwide. The lack of guidelines and a consensus for their management, and the emergence of resistance of community-based uropathogens to the available therapeutic options, make it necessary to develop recommendations to guide clinicians on the optimal approach to these entities. Objective: Define a consensus for the empiric management of asymptomatic bacteriuria and Urinary Tract Infection (UTI) in adults and pregnant women in Colombia. Methods: We carried out a consensus methodology with experts in urology, infectious diseases, internal medicine, gynecology and clinical microbiology; based on reviewing the available literature on the related terms, and emphasizing local studies. Results: We developed a management algorithm for the empirical treatment of uncomplicated lower UTI in adults with urinary antiseptics such as nitrofurantoin and fosfomycin trometamol as first line, with specific therapeutic recommendations for the treatment of asymptomatic bacteriuria in pregnant women. Additionally, we created a decision algorithm for processing urine cultures. Frequent recurrence or relapse justifies referral to urology and infectious disease professionals. Conclusions: We generated straightforward and easy-to-implement recommendations for the diagnosis and management of UTI in adults and pregnant women, and in cases where it is necessary to treat asymptomatic bacteriuria, with effective therapeutic and narrow spectrum options.

RESUMO

Invasive isolates of staphylococci and enterococci were collected from 15 tertiary care centres in five Colombian cities from 2001 to 2002. A total of 597 isolates were available for analysis. Identification was confirmed by both automated methods and multiplex PCR assays in a central laboratory. Staphylococcus aureus and coagulase-negative staphylococci (CoNS) corresponded to 49.6% and 29.6% of isolates, respectively, and 20.8% were identified as enterococci. MICs of ampicillin, ciprofloxacin, chloramphenicol, erythromycin, gentamicin, linezolid, oxacillin, rifampicin, teicoplanin, tetracycline, trimethoprim/sulfamethoxazole (SXT) and vancomycin were determined using an agar dilution method as appropriate. Screening for vancomycin-resistant S. aureus was also carried out on brain-heart infusion agar plates supplemented with vancomycin. The presence of mecA and van genes was investigated in methicillin-resistant staphylococci and glycopeptide-resistant enterococci (GRE), respectively. All staphylococci were susceptible to vancomycin, teicoplanin and linezolid. No VISA isolates were found. In S. aureus and CoNS, the lowest rates of resistance were found for SXT (7.4%) and chloramphenicol (10.7%), respectively. Resistance to oxacillin in S. aureus and CoNS was 52% and 73%, respectively. The mecA gene was detected in 97.5% of methicillin-resistant S. aureus isolates. In enterococci, resistance to glycopeptides was 9.7%: vanA (58.3%) and vanB (41.7%) genes were found. Pulsed-field gel electrophoresis indicated that the GRE isolates were closely related. Rates of resistance to ampicillin, ciprofloxacin, chloramphenicol, rifampicin and high levels of gentamicin and streptomycin were 9.7%, 27.4%, 8.9%, 43%, 17% and 28.2%, respectively. All enterococci were susceptible to linezolid.
