RESUMEN
OBJECTIVE: To describe the epidemiology of Enterobacterales producing carbapenemases (EPC) in a tertiary hospital. METHODS: A retrospective observational study, all patients with a positive sample for EPC treated in hospitalization or in the Emergency Department were included, between January 1, 2014 and December 31, 2016. RESULTS: A total of 272 patients (316 samples) were included: 155 (57%) male. Mean age of 70.4 years (95% CI 68.2 -72.7). Mean Charlson index was 3.6 (95% CI 3.4-3.8). In 63.2% the acquisition was nosocomial, in 35.3% it was health-care associated (HA). 55.1% presented infection, the most frequent infection was urinary tract infection (UTI) (58.7%). The most frequent species were Klebsiella pneumoniae (62.7%) and Enterobacter cloacae (10.1%). The most frequent types of carbapenemase were OXA-48 (53.8%) and VIM (43%). The nosocomial acquisition was associated with the male gender, transplantation, immunosuppression, admission to the Intensive Care Unit (ICU) or surgical service, prior antibiotic treatment, Enterobacter, VIM, respiratory and intra-abdominal infections. The HA acquisition was associated with age and comorbidity, nursery home origin, bladder catheterization, greater number of outpatient procedures, previous hospital admission, K. pneumoniae and E. coli, OXA-48, coproduction of extended spectrum betalactamases, UTI and sepsis. CONCLUSIONS: Patients who acquire EPC in nursery homes frequently have an infection. Patients with nosocomial acqui-sition are colonized by EPC in the ICU, in relation to invasive procedures and transplantation. This population has a higher mortality due to developing respiratory infections by EPC.

UNLABELLED: This paper is a corrigendum to the previously published paper: "Antimicrobial stewardship in patients recently transferred to a ward from the ICU" [Rev Esp Quimioter. 2014 Mar;27(1):46-50.] This corrigendum was prepared in order to correct some erroneous comments included in the discussion section. First, it should be pointed out that there could have been several suitable options for treating many infections and that, therefore, the word "inadequate" was not the most appropriate in this situation. In addition, some comments about the interpretation of microbiological results made by ICU physicians have been removed from the first article because this variable was not included in the study. Finally, another change made to the discussion was to clarify the ICU physicians' alleged low level of compliance with advice given by infectious disease specialists. This has been suggested in previous studies it cannot be substantiated when analyzing the results of the study. PURPOSE: Inappropriate use of antibiotics is an important health problem that is related to increasing bacterial resistance. Despite its relevance, many health institutions assign very limited resources to improving prescribing practices. An antimicrobial stewardship programme (APS) centred on patients discharged from the ICU could efficiently undertake this task. METHODS: During this six month study the main activity was performing a programmed review of antimicrobial prescriptions in patients transferred to the ward from the ICU. In the case of amendable antimicrobial treatment, a recommendation was included in the medical record. RESULTS: A total of 437 antimicrobial prescriptions for 286 patients were revised during a six month period and a total of 271 prescriptions (62%) in 183 patients were considered to be amendable. In most of these cases, treatment could have been reduced taking into consideration each patient's clinical improvement and their location in a hospital area with a lower risk of infection due to resistant bacteria. The most common advice was antimicrobial withdrawal (64%), antimicrobial change (20%) and switching to oral route (12%). Proposed recommendations were addressed in 212 cases (78%). There was no significant difference in adherence with respect to the type of recommendation (p=0.417). There was a 5% lower use of antibiotics during the year the study was conducted compared to the previous one. CONCLUSIONS: ASPs centred on patients discharged from the ICU may be an efficient strategy to ameliorate antimicrobial use in hospitals.

This article reports the contamination of a batch of liquid soap for hospital use with Raoultella planticola. The micro-organism was first identified as Klebsiella pneumoniae due to the inability of automated systems to characterize this species. There is a need to strengthen the inspection of cosmetic products to be used in the hospital setting. It is recommended that hospitalized patients at the highest risk of infection should use antimicrobial soaps for personal hygiene. The incidence of infections due to R. planticola is unknown as it is usually misclassified as Klebsiella spp. by automated systems.

BACKGROUND: The aim of this study was to assess the efficacy of tigecycline in the treatment of infections due to carbapenemase-producing Klebsiella pneumoniae (CPKP) in critically ill patients. METHODS: A retrospective observational study was conducted in critically ill patients receiving different tigecycline doses for severe CPKP infections. We evaluated demographic data, localization and severity of infection, response to therapy, and mortality. RESULTS: Fifteen patients received tigecycline for 16 episodes of CPKP infection. The main infections were pneumonia (31%), urinary tract infection (31%), peritonitis (20%), catheter-related bacteraemia (12%), and meningitis (6%). Most infections were complicated with severe sepsis (44%), septic shock (12%), and/or bacteraemia (19%). The daily maintenance dose of tigecycline was 200 mg in 10 episodes and 100 mg in 6 episodes. The overall 30-day mortality rate was 25%. Univariate analysis showed that mortality was significantly associated (p < 0.01) with mean APACHE II and SOFA scores and the presence of immunosuppression, but not with the tigecycline dose. CONCLUSIONS: Tigecycline appears to be an effective therapy for severe infections due to CPKP in critically ill patients. Mortality is related to the severity of the underlying disease. We observed no benefit from a higher maintenance dose of tigecycline, although the number of patients included in the study was too small to draw any general conclusions in this regard.

El tratamiento inicial de las infecciones del tracto urinario (ITU) es empírico por lo que es prioritario conocer la resistencia antibiótica de los microorganismos más frecuentes en una población. Además, tras la sospecha de pielonefritis aguda se debe descartar la presencia de cicatriz renal que puede dar lugar a complicaciones posteriores. Presentamos un estudio longitudinal y retrospectivo de todos los menores de 14 años diagnosticados de ITU desde el 1 de enero del 2009 hasta el 31 de diciembre del 2009. Se analizaron los datos de sensibilidad a antimicrobianos de los patógenos urinarios más importantes, el seguimiento posterior y la presencia de cicatrices. Las bacterias aisladas con mayor frecuencia fueron: Escherichia coli (80%) Proteus mirabillis (9,7%) y Klebsiella pneumoniae (4,2%). En el antibiograma, E. coli presentó una alta sensibilidad frente a fosfomicina (99,1%), cefotaxima (98,2%) cefuroxima (97,3%) y gentamicina (95,6%). La sensibilidad obtenida frente a amoxicilina-clavulánico fue del 83,2%, mientras que la obtenida frente a cotrimoxazol fue del 78,9%.Se encontraron cicatrices pospielonefríticas en el 19% de los pacientes con ITU febril, 17% de los no ingresados y 20% de los ingresados(AU)
The initial treatment of the urinary tract infections (UTI) is empirical and it is a priority to determine the antibiotic resistance of most common germs in a population. Furthermore, due to the suspicion of acute pyelonephritis the presence of renal scarring should be ruled out as this may lead to further complications. A retrospective longitudinal study was performed on all children under 14 years diagnosed with UTI from January 1 2009 to December 31 2009. The in vitro susceptibility to the most important urinary pathogens was analysed, along with the presence of scars, and a subsequent follow-up. The most frequently isolated bacteria were E. coli (80%), P. mirabilis (9.7%) and K. pneumoniae (4.2%). In the antibiogram, E coli showed a high sensitivity to fosfomycin (99.1%), cefotaxime (98.2%) cefuroxime (97.3%) and gentamicin (95.6%). The sensitivity obtained against amoxicillin-clavulanate was 83.2%, while that obtained against cotrimoxazole was 78.9%.Post-pyelonephritis scars were found in 19% of patients with febrile UTI, 17% out-patients and 20% of those admitted(AU)

We present a case of recurrent subdural post-surgical empyema by Proprionibacterium acnes after a first drained empyema in which no microbiological diagnosis was reached. P. acnes is a gram-positive anaerobic organism which is part of the saprophytic flora of the skin and others parts of the body. However, it can cause infections, as in the central nervous system, especially post-surgical infections in which can be the second more frequent organism after Staphylococcus aureus. P. acnes grows slowly and shows better growth in liquid anaerobic media. It is usually resistant to metronidazol and sensitive to penicillin. In postoperative central nervous system infections we must take into account the possibility of this organism, process the sample properly and keep touch with the Microbiology Department.

We present a case of endocarditis caused by Aspergillus in a lung transplant (LT) patient and review 6 previously reported cases. All cases were caused by Aspergillus fumigatus. Five patients (71%) were transplanted due to cystic fibrosis. None of the patients had any previously known valvular heart disease. The time that elapsed between LT surgery and the diagnosis of Aspergillus endocarditis was 8±6 months. Large peripheral emboli were observed in 6 patients (85%); blood cultures were negative in all. Transthoracic echocardiography did not detect the presence of vegetations in 3 patients (43%); the vegetations measured >1.5 cm in all cases. Five patients (71%) died from disseminated disease. Both survivors underwent combined therapy with antifungal drugs and surgical treatment.

Se presenta un caso de recidiva de infección postquirúrgica en forma de empiema subdural por Proprionibacterium acnes tras un primer empiemadrenado en el que no se llegó al diagnóstico microbiológico. P acnes es un microorganismo gram positivo, anaerobio, que forma parte de la flora saprófita de la piel y de otras zonas del organismo. Sin embargo puede producir infecciones, entre otras localizaciones, en el sistema nervioso central (SNC), especialmente infecciones postquirúrgicas en las que puede llegar a ser el segundo germen en frecuencia después de Staphylococcusaureus. Es de crecimiento lento y suele crecer mejor en medios anaeróbicos líquidos. Suele ser resistente almetronidazol y sensible a penicilinas. En las infecciones postquirúrgicas del sistema nervioso central hay que tener en cuenta la posibilidad de este microorganismo, procesar las muestras de forma adecuada y mantenernos en contacto con el Servicio de Microbiología (AU)

Introducción. Este estudio se propone evaluar el pronóstico de las infecciones del tracto urinario (ITU) tratadas empíricamente con tratamiento antibiótico inadecuado. Material y método. Estudio de cohortes prospectivo, de pacientes mayores de 18 años de edad, atendidos en un servicio de urgencias hospitalario entre el 01/02 y el 31/05 de 2007 por síntomas miccionales, acompañados de piuria (>10leucocitos/mm3 de orina no centrifugada) o tira reactiva positiva para nitritos-leucocitos y urocultivo con >103 unidades formadoras de colonias. Se consideró que el tratamiento antibiótico prescrito empíricamente era adecuado si la bacteria aislada era sensible y se había prescrito por un tiempo correcto. Se consideró que hubo fracaso terapéutico cuando persistía la sintomatología tras 5 días de tratamiento. Se registraron la edad, el sexo, la presencia de sonda vesical permanente, el tipo de ITU, hospitalización en los 3 meses previos, la procedencia del paciente y las enfermedades asociadas. Resultados. Se aislaron 177 bacterias en 168 pacientes. En 29 casos (17,3%) el microorganismo aislado era resistente al antibiótico prescrito. En tan solo 6 pacientes hubo fracaso terapéutico, aunque no precisaron ingreso hospitalario. Los pacientes que vivían en una residencia de ancianos (13,7 vs 2,2%, p=0,015) o que habían sido ingresados durante los 3 meses previos (20,6 vs 4,3%, p=0,039) presentaron un mayor riesgo de recibir tratamiento inadecuado. Conclusiones. El pronóstico de los pacientes atendidos en Servicios de Urgencias Hospitalarios por ITU con tratamiento antibiótico discordante es favorable en la mayoría de los casos. Sería recomendable la realización de urocultivo en pacientes con mayor riesgo de padecer ITU por un microorganismo resistente(AU)
Introduction. This study aims to evaluate the prognosis of urinary tract infections (UTI) treated empirically with inadequate antibiotic treatment. Material and Methods. Prospective cohort study of patients over 18 years of age, attended in the hospital emergency service between 01/02 and 31/05 of 2007, due to micturation symptoms, accompanied by pyuria (>10leukocytes/mm3 of uncentrifuged urine) or positive reactive strip for nitrites-leukocytes and urine culture with >103 colony forming units. It was considered that the antibiotic treatment prescribed empirically was adequate if the bacteria isolated was sensitive and had been prescribed for the correct time. It was considered that there was therapeutic failure when the symptoms persisted after 5 days of treatment. Age, gender, presence of indwelling bladder catheter, type of UTI, hospitalization in the previous 3 months, origin of the patient and associated diseases were recorded. Results. A total of 177 bacteria were isolated in 168 patients. In 29 cases (17.3%), the microorganism isolated was resistant to the antibiotic prescribed. There was thereaputic failure in only 6 patients, although they did not required hospital admission. The patients who lived in a residential home for the elderly (13.7% vs 2.2%, P=0.015) or who had been hospitalized during the previous 3 months (20.6% vs 4.3%, p=0.039) had a greater risk of receiving inadequate treatment. Conclusions. The prognosis of the patients attended in the emergency hospital service due to UTI with discordant antibiotic treatment is favorable in most of the cases. Performing urine culture in patients with greater risk of suffering UTI due to a resistant microorganism would be recommendable(AU)

INTRODUCTION: This study aims to evaluate the prognosis of urinary tract infections (UTI) treated empirically with inadequate antibiotic treatment. MATERIAL AND METHODS: Prospective cohort study of patients over 18 years of age, attended in the hospital emergency service between 01/02 and 31/05 of 2007, due to micturation symptoms, accompanied by pyuria (>10 leukocytes/mm(3) of uncentrifuged urine) or positive reactive strip for nitrites-leukocytes and urine culture with >10(3) colony forming units. It was considered that the antibiotic treatment prescribed empirically was adequate if the bacteria isolated was sensitive and had been prescribed for the correct time. It was considered that there was therapeutic failure when the symptoms persisted after 5 days of treatment. Age, gender, presence of indwelling bladder catheter, type of UTI, hospitalization in the previous 3 months, origin of the patient and associated diseases were recorded. RESULTS: A total of 177 bacteria were isolated in 168 patients. In 29 cases (17.3%), the microorganism isolated was resistant to the antibiotic prescribed.

CONCLUSIONS: The prognosis of the patients attended in the emergency hospital service due to UTI with discordant antibiotic treatment is favorable in most of the cases. Performing urine culture in patients with greater risk of suffering UTI due to a resistant microorganism would be recommendable.

Organ transplant recipients are at increased risk for Aspergillus infections. Cutaneous aspergillosis (CA) occurs less frequently and is poorly characterized. The case of a lung transplant recipient with CA is presented. Six months after transplantation, 3 painful skin nodules appeared, with 1 each in the right calf, left arm, and upper back. Exudate from the leg nodule yielded Aspergillus fumigatus. Computed tomography of the chest showed bilateral hilar lymphadenopathy, but <1 cm in size. The case could be the result of Aspergillus dissemination from a hypothetical asymptomatic pulmonary infection. The lack of lung radiological signs could be related to prophylactic treatment with inhaled liposomal amphotericin B, which could have prevented clinically evident Aspergillus lung infection. The patient was treated with voriconazole, which was maintained for 3 months. The patient recovered completely.

Zygomycetes are among the most frequent causes of non-Aspergillus mycelial fungal infections in transplant recipients. We have described a single case of breakthrough zygomycosis. A young Japanese woman presented because of idiopathic fulminant hepatitis and renal failure. On the third day of admission, she underwent orthotopic liver transplantation. A considerable amount of red blood cells and fresh frozen plasma were transfused during surgery. On posttransplant day 2, Candida albicans was isolated from respiratory secretions; prophylactic caspofungin was prescribed. During the next 6 days, C albicans was isolated from tracheal secretions, surgical wound, and exudates and stools. Ventilator-associated pneumonia was diagnosed day 4. Her renal function did not improve during the postoperative period; the patient continued on hemodialysis. On day 28, a dark blue eschar due to zygomycosis was detected on the skin of the nose. Tracheal and nasal exudates yielded Rhizopus sp. The patient died 12 hours later due to multiorgan failure with hypothermia. The fatal evolution in this case may be related to a presumed brain infarction after progressive vessel fungal invasion. The presented case had 2 risk factors related to zygomycosis. A high index of suspicion is required in transplant recipients with risk factors for zygomycosis. Early diagnosis and surgery with appropriate systemic fungal drugs (amphotericin B) are mandatory to improve the prognosis.

BACKGROUND: Postsurgical meningitis is a rare complication that is accompanied by an increase of hospital stay and high mortality. Some of these cases are not due to a true infection but due to an aseptic inflammation of the meninges denominated aseptic postsurgical meningitis (APSM). Proper identification of these cases would allow better use of antimicrobial drugs. METHODS: A retrospective study of patients with postsurgical meningitis in a universitary hospital for 14 years. We describe the clinical characteristics of patients with postsurgical bacterial meningitis (PBM) compared to those of patients with APSM. RESULTS: During the studied period 35 patients (71%) with PBM and 14 patients (29%) with (APSM) were identified. The mean age of patients with PBM was similar to that of patients with APSM. There was a male predominance in the group of PBM (71%) compared with patients with APSM (36%, p = 0.020). Patients with intracranial hemorrhage tended to present more cases of APSM (64%) than of PBM (34%, p = 0.055). Patients undergoing posterior fossa craniotomy (p = 0.092) and those receiving steroids (p = 0.051) showed a greater tendency to suffer APSM. It was also noted a trend towards present PBM in patients who had suffered an infection in the previous month (p = 0.072). There were seven patients with PBM (20%) with a cell count above 5000 cells/mm3 in CSF, values not found in any patients with APSM. No differences were detected in the glycorrachia and proteinorrachia between the two groups. The most common bacteria isolated were coagulase negative Staphylococcus and S. aureus. In 5 patients (14%) non fermenting gram-negative bacillus (Pseudomonas aeruginosa and Acinetobacter spp) were isolated. There were no deaths attributed to any type of postsurgical meningitis. CONCLUSION: Patients admitted for brain haemorrhage, undergoing posterior fossa surgery or receiving steroids tend to develop APSM. A CSF cell count above 5000 cells / mm3 strongly suggests MBP.

Proper identification of these cases wouldallow better use of antimicrobial drugs.Methods. A retrospective study of patients withpostsurgical meningitis in a universitary hospital for14 years. We describe the clinical characteristics ofpatients with postsurgical bacterial meningitis (PBM)compared to those of patients with APSM.Results. During the studied period 35 patients (71%)with PBM and 14 patients (29%) with (APSM) wereidentified. The mean age of patients with PBM wassimilar to that of patients with APSM. There was a malepredominance in the group of PBM (71%) comparedwith patients with APSM (36%, p = 0.020). Patientswith intracranial hemorrhage tended to present morecases of APSM (64%) than of PBM (34%, p = 0.055).Patients undergoing posterior fossa craniotomy (p =0.092) and those receiving steroids (p = 0.051) showeda greater tendency to suffer APSM. It was also noted (...) (AU)

La tromboflebitis supurada es una complicación muy infrecuente de la cateterización venosa central. La mayoría de los casos están producidos por especies de estafilococos. Se presenta el caso de una mujer de 22 años natural de Colombia sin hábitos tóxicos que estaba ingresada tras haber sido intervenida de un astrocitoma temporal izquierdo de grado II. A los 9 días de la implantación de un catéter en la vena subclavia derecha presentó fiebre elevada, escalofríos y tiritona junto a tumefacción progresiva laterocervical derecha y odinofagia. Tenía leucocitosis de 26.300 células/µl y líquido cefalorraquídeo normal. Tras retirar el catéter se aisló Staphylococcus aureus en la punta del catéter y en los cuatro frascosobtenidos en los hemocultivos. Una TAC de cabeza y de cuello con contraste evidenció distensión y ausencia de contraste en la vena yugular interna derecha. La paciente evolucionó satisfactoriamente con cloxacilina, gentamicina y heparina de bajo peso molecular
Suppurative thrombophlebitis is a very infrequent complication of the central venous catheterization. The majority of the cases are produced by species of staphylococci. A 22-year-old colombian-woman, student, without toxic habits was admitted because of temporary left astrocytoma (grade II). Nine days after implementing a catheter in the right subclavianve in she presented high fever (39.5 º C), shivers, progressive rightside neck swelling and odinofagia. She had leukocytosis (26,300 cells/µl) and normal cerebrospinal fluid. After with drawing the catheter, Staphylococcus aureus was isolated in the tip of the catheter and in four bottles of blood cultures. A neck CT demonstrated expansion and absence of contrast in the right internal jugular vein. The patient evolved satisfactorily with cloxacillin, gentamycin and low molecular weight heparin
