Efficacy and safety of a structured de-escalation from antipseudomonal ß-lactams in bloodstream infections due to Enterobacterales (SIMPLIFY): an open-label, multicentre, randomised trial.

BACKGROUND: De-escalation from broad-spectrum to narrow-spectrum antibiotics is considered an important measure to reduce the selective pressure of antibiotics, but a scarcity of adequate evidence is a barrier to its implementation. We aimed to determine whether de-escalation from an antipseudomonal ß-lactam to a narrower-spectrum drug was non-inferior to continuing the antipseudomonal drug in patients with Enterobacterales bacteraemia. METHODS: An open-label, pragmatic, randomised trial was performed in 21 Spanish hospitals. Patients with bacteraemia caused by Enterobacterales susceptible to one of the de-escalation options and treated empirically with an antipseudomonal ß-lactam were eligible. Patients were randomly assigned (1:1; stratified by urinary source) to de-escalate to ampicillin, trimethoprim-sulfamethoxazole (urinary tract infections only), cefuroxime, cefotaxime or ceftriaxone, amoxicillin-clavulanic acid, ciprofloxacin, or ertapenem in that order according to susceptibility (de-escalation group), or to continue with the empiric antipseudomonal ß-lactam (control group). Oral switching was allowed in both groups. The primary outcome was clinical cure 3-5 days after end of treatment in the modified intention-to-treat (mITT) population, formed of patients who received at least one dose of study drug. Safety was assessed in all participants. Non-inferiority was declared when the lower bound of the 95% CI of the absolute difference in cure rate was above the -10% non-inferiority margin. This trial is registered with EudraCT (2015-004219-19) and ClinicalTrials.gov (NCT02795949) and is complete. FINDINGS: 2030 patients were screened between Oct 5, 2016, and Jan 23, 2020, of whom 171 were randomly assigned to the de-escalation group and 173 to the control group. 164 (50%) patients in the de-escalation group and 167 (50%) in the control group were included in the mITT population. 148 (90%) patients in the de-escalation group and 148 (89%) in the control group had clinical cure (risk difference 1·6 percentage points, 95% CI -5·0 to 8·2). The number of adverse events reported was 219 in the de-escalation group and 175 in the control group, of these, 53 (24%) in the de-escalation group and 56 (32%) in the control group were considered severe. Seven (5%) of 164 patients in the de-escalation group and nine (6%) of 167 patients in the control group died during the 60-day follow-up. There were no treatment-related deaths. INTERPRETATION: De-escalation from an antipseudomonal ß-lactam in Enterobacterales bacteraemia following a predefined rule was non-inferior to continuing the empiric antipseudomonal drug. These results support de-escalation in this setting.

Efficacy and safety of oral fosfomycin for asymptomatic bacteriuria in kidney transplant recipients: Results from a Spanish multicenter cohort.

Current guidelines recommend against systematic screening or treating asymptomatic bacteriuria (AB) among kidney transplant (KT) recipients, although the evidence regarding episodes occurring early after transplantation or in the presence of anatomical abnormalities is inconclusive. Oral fosfomycin may constitute a good option for the treatment of post-transplant AB, particularly due to the emergence of multidrug-resistant (MDR) uropathogens. Available clinical evidence supporting its use in this specific setting, however, remains scarce. We performed a retrospective study in 14 Spanish institutions from January 2005 to December 2017. Overall, 137 episodes of AB diagnosed in 133 KT recipients treated with oral fosfomycin (calcium and trometamol salts) with a test-of-cure urine culture within the first 30 days were included. Median time from transplantation to diagnosis was 3.1 months (interquartile range [IQR]: 1.1 - 10.5). Most episodes (96.4% [132/137]) were caused by gram-negative bacteria (GNB), and 56.9% (78/137) were categorized as MDR (extended-spectrum ß-lactamase-producing Enterobacterales [20.4%] and carbapenem-resistant GNB [2.9%]). Rate of microbiological failure at month 1 was 40.1% (95% confidence interval [95%CI]: 31.9 - 48.9) for the whole cohort and 42.3% (95%CI: 31.2 - 54.0) for episodes due to MDR pathogens. Previous urinary tract infection (odds ratio [OR]: 2.42; 95%CI: 1.11 - 5.29; P-value = 0.027) and use of fosfomycin as salvage therapy (OR: 8.31; 95%CI: 1.67 - 41.35; P-value = 0.010) were predictors of microbiological failure. No severe treatment-related adverse event were detected. Oral fosfomycin appears to be a suitable and safe alternative for the treatment (if indicated) of AB after KT, including those episodes due to MDR uropathogens.

Comorbidity and Prognosis in Octogenarians with Infective Endocarditis.

Background. Infective endocarditis (IE) in older patients is associated with a high morbidity, mortality, and functional impairment. The purpose of this study was to describe the current profile of IE in octogenarians and to analyze the prognostic impact of baseline comorbidities in this population. Methods. Patients ≥ 80 years and definite IE from the Spanish IE Prospective Database were included. The effect of Charlson Comorbidity Index (CCI) on in-hospital and 12-month mortality was analyzed. Results. From 726 patients, 357 (49%) had CCI ≥ 3 and 369 (51%) CCI < 3. A total of 265 patients (36.6%) died during hospital admission and 338 (45.5%) during 1-year follow-up. CCI ≥ 3 was an independent predictor of in-hospital and 1-year mortality (odds ratio 1.46, 95% confidence interval 1.07−1.99, p = 0.017; hazard ratio 1.34, 95% confidence interval 1.08−1.66, p = 0.007, respectively). Surgical management was less common in patients with high comorbidity (CCI ≥ 3 68 [19.0%] vs. CCI < 3 112 ((30.4%) patients, p < 0.01). From 443 patients with surgical indication, surgery was only performed in 176 (39.7%). Patients with surgical indication treated conservatively had higher mortality than those treated with surgery (in-hospital mortality: 147 (55.1%) vs. 55 (31.3%), p < 0.001), (1-year mortality: 172 (64.4%) vs. 68 [38.6%], p < 0.001). Conclusion. About half of octogenarians with IE had high comorbidity with CCI ≥ 3. CCI ≥ 3 was a strong independent predictor of in-hospital and 1-year mortality. Our data suggest that the underperformance of cardiac surgery in this group of patients might have a role in their poor prognosis.

Elevated levels of serum CDCP1 in individuals recovering from severe COVID-19 disease.

BACKGROUND: COVID-19 survivors report residual lung abnormalities after discharge from the hospital. The aim of this study was to identify biomarkers in serum and induced sputum samples from patients after hospitalization for COVID-19. METHODS: Patients admitted to hospitals in Spain with laboratory-confirmed COVID-19 were recruited for this study. SARS-CoV-2-infected patients were divided into groups with mild/moderate and severe disease according to the severity of their symptoms during hospitalization. Levels of 92 biomarkers were measured in serum and induced sputum samples. RESULTS: A total of 108 patients (46.2% severe cases) were included in this study. The median number of days after the onset of symptoms was 104. A significant difference was observed in diffusing capacity for carbon monoxide (DLCO), an indicator of lung function, whereby DLCO <80% was significantly lower in severe cases (p <0.001). Differences in inflammatory biomarkers were observed between patients with mild/moderate and severe disease. For some biomarkers, correlations in serum and induced sputum levels were detected. Independent predictors of severe disease were DLCO <80% and the serum CDCP1 value. CONCLUSIONS: Higher levels of CDCP1 remain after hospital discharge and are associated with the severity of COVID-19. The possible prognostic implications warrant further investigation.

Epidemiological trends of HIV/HCV coinfection in Spain, 2015-2019.

OBJECTIVES: We assessed the prevalence of anti-hepatitis C virus (HCV) antibodies and active HCV infection (HCV-RNA-positive) in people living with HIV (PLWH) in Spain in 2019 and compared the results with those of four similar studies performed during 2015-2018. METHODS: The study was performed in 41 centres. Sample size was estimated for an accuracy of 1%. Patients were selected by random sampling with proportional allocation. RESULTS: The reference population comprised 41 973 PLWH, and the sample size was 1325. HCV serostatus was known in 1316 PLWH (99.3%), of whom 376 (28.6%) were HCV antibody (Ab)-positive (78.7% were prior injection drug users); 29 were HCV-RNA-positive (2.2%). Of the 29 HCV-RNA-positive PLWH, infection was chronic in 24, it was acute/recent in one, and it was of unknown duration in four. Cirrhosis was present in 71 (5.4%) PLWH overall, three (10.3%) HCV-RNA-positive patients and 68 (23.4%) of those who cleared HCV after anti-HCV therapy (p = 0.04). The prevalence of anti-HCV antibodies decreased steadily from 37.7% in 2015 to 28.6% in 2019 (p < 0.001); the prevalence of active HCV infection decreased from 22.1% in 2015 to 2.2% in 2019 (p < 0.001). Uptake of anti-HCV treatment increased from 53.9% in 2015 to 95.0% in 2019 (p < 0.001). CONCLUSIONS: In Spain, the prevalence of active HCV infection among PLWH at the end of 2019 was 2.2%, i.e. 90.0% lower than in 2015. Increased exposure to DAAs was probably the main reason for this sharp reduction. Despite the high coverage of treatment with direct-acting antiviral agents, HCV-related cirrhosis remains significant in this population.

Usefulness of the COVID-GRAM and CURB-65 scores for predicting severity in patients with COVID-19.

AIM: The aim of this study was to determine the usefulness of COVID-GRAM and CURB-65 scores as predictors of the severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Caucasian patients. METHODS: This was a retrospective observational study including all adults with SARS-CoV-2 infection admitted to Hospital Universitario Marqués de Valdecilla from February to May 2020. Patients were stratified according to COVID-GRAM and CURB-65 scores as being at low-medium or high risk of critical illness. Univariate analysis, multivariate logistic regression models, receiver operating characteristic curve, and area under the curve (AUC) were calculated. RESULTS: A total of 523 patients were included (51.8% male, 48.2% female; mean age 65.63 years (standard deviation 17.89 years)), of whom 110 (21%) presented a critical illness (intensive care unit admission 10.3%, 30-day mortality 13.8%). According to the COVID-GRAM score, 122 (23.33%) patients were classified as high risk; 197 (37.7%) presented a CURB-65 score ≥2. A significantly greater proportion of patients with critical illness had a high COVID-GRAM score (64.5% vs 30.5%; P < 0.001). The COVID-GRAM score emerged as an independent predictor of critical illness (odds ratio 9.40, 95% confidence interval 5.51-16.04; P < 0.001), with an AUC of 0.779. A high COVID-GRAM score showed an AUC of 0.88 for the prediction of 30-day mortality, while a CURB-65 ≥2 showed an AUC of 0.83. CONCLUSIONS: The COVID-GRAM score may be a useful tool for evaluating the risk of critical illness in Caucasian patients with SARS-CoV-2 infection. The CURB-65 score could be considered as an alternative.

Catheter-related bloodstream infections: predictive factors for Gram-negative bacteria aetiology and 30 day mortality in a multicentre prospective cohort.

BACKGROUND: Catheter-related bloodstream infections (CRBSIs) increase morbidity and mortality, prolong hospitalization and generate considerable medical costs. Recent guidelines for CRBSI recommend empirical therapy against Gram-positive bacteria (GPB) and restrict coverage for Gram-negative bacteria (GNB) only to specific circumstances. OBJECTIVES: To investigate predictors of GNB aetiology in CRBSI and to assess the predictors of outcome in patients with CRBSI. METHODS: Patients with CRBSI were selected from the PROBAC cohort, a prospective, observational, multicentre national cohort study including patients with bloodstream infections consecutively admitted to 26 Spanish hospitals in a 6 month period (October 2016-March 2017). Outcome variables were GNB aetiology and 30 day mortality. Adjusted analyses were performed by logistic regression. RESULTS: Six hundred and thirty-one episodes of CRBSI were included in the study. Risk factors independently related to GNB aetiology were central venous catheter (CVC) [OR 1.60 (95% CI: 1.05-2.44), P = 0.028], sepsis/septic shock [OR: 1.76 (95% CI: 1.11-2.80), P = 0.016], antibiotic therapy in the previous 30 days [OR: 1.56 (95% CI: 1.02-2.36), P = 0.037], neutropenia <500/µL [OR: 2.01 (95% CI: 1.04-3.87), P = 0.037] and peripheral vascular disease [OR: 2.04 (95% CI: 1.13-3.68), P = 0.018]. GNB were not associated with increased mortality in adjusted analysis, while removal of catheter [OR: 0.24 (95% CI: 0.09-0.61), P = 0.002] and adequate empirical treatment [OR: 0.37 (95% CI: 0.18-0.77), P = 0.008] were strong protective factors. CONCLUSIONS: Our study reinforces the recommendation that empirical coverage should cover GNB in patients presenting with sepsis/septic shock and in neutropenic patients. Catheter removal and adequate empirical treatment were both protective factors against mortality in patients with CRBSI.

Oral fosfomycin for the treatment of lower urinary tract infections among kidney transplant recipients-Results of a Spanish multicenter cohort.

Oral fosfomycin may constitute an alternative for the treatment of lower urinary tract infections (UTIs) in kidney transplant recipients (KTRs), particularly in view of recent safety concerns with fluroquinolones. Specific data on the efficacy and safety of fosfomycin in KTR are scarce. We performed a retrospective study in 14 Spanish hospitals including KTRs treated with oral fosfomycin (calcium and trometamol salts) for posttransplant cystitis between January 2005 and December 2017. A total of 133 KTRs developed 143 episodes of cystitis. Most episodes (131 [91.6%]) were produced by gram-negative bacilli (GNB), and 78 (54.5%) were categorized as multidrug resistant (including extended-spectrum ß-lactamase-producing Enterobacteriaceae [14%] or carbapenem-resistant GNB [3.5%]). A median daily dose of 1.5 g of fosfomycin (interquartile range [IQR]: 1.5-2) was administered for a median of 7 days (IQR: 3-10). Clinical cure (remission of UTI-attributable symptoms at the end of therapy) was achieved in 83.9% (120/143) episodes. Among those episodes with follow-up urine culture, microbiological cure at month 1 was achieved in 70.2% (59/84) episodes. Percutaneous nephrostomy was associated with a lower probability of clinical cure (adjusted odds ratio: 10.50; 95% confidence interval: 0.98-112.29; P = 0.052). In conclusion, fosfomycin is an effective orally available alternative for treating cystitis among KTRs.

Role of age and comorbidities in mortality of patients with infective endocarditis.

PURPOSE: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. METHODS: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. RESULTS: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32-3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39-1.88),and non-performed surgery (HR:1.64;95% CI:11.16-1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. CONCLUSION: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group.

Daptomycin treatment in Gram-positive vascular graft infections.

BACKGROUND: Daptomycin is a bactericidal antibiotic approved for the treatment of skin and soft tissue infections and right-side endocarditis. However, there is a lack of published data outlining its usefulness in vascular graft infections (VGI). The aim of this study was to describe the clinical experience of daptomycin use in the treatment of VGI caused by Gram-positive bacteria. METHODS: This was a retrospective cohort study of patients diagnosed with VGI receiving daptomycin at a tertiary care hospital during the period January 2010 to December 2012. RESULTS: Of a total 1066 consecutive patients who had undergone vascular grafts (VG), 25 were diagnosed with VGI. Fifteen of these patients (11 prosthetic VG, three autologous VG, one both types) received daptomycin (median dose 6.7mg/kg/day, range 4.1-7.1mg/kg/day; median age 69 years, range 45-83 years; 80% male). The infected bypass was removed in 13 cases. The most common reason for selecting daptomycin was kidney failure (53%). The Gram-positive organisms isolated were coagulase-negative Staphylococcus (n=10), Staphylococcus aureus (n=3) (two methicillin-resistant S. aureus), Enterococcus faecium (n=2), and Enterococcus faecalis (n=1). The mean follow-up was 69 months (interquartile range 48-72 months). Ten patients (66.7%) achieved complete healing of the VGI. A recurrence of the infection was observed in 100% of patients in whom the bypass was not removed. Among patients who did not achieve complete healing, one needed a supracondylar amputation and one died as a consequence of infection. Five patients received treatment with rifampicin in addition to daptomycin and they were all cured. CONCLUSIONS: The use of daptomycin and surgery for Gram-positive VGI was effective and well tolerated, and this may be a good alternative for the treatment of VGI in patients with peripheral arterial disease in whom renal insufficiency is common.

Bacteriobilia: un problema sin resolver / Bacteriobilia: a non-resolved problem

La vía biliar habitualmente es estéril, y el aislamiento de microorganismos (bacteriobilia) se ha relacionado con diversos factores, como la edad, el drenaje biliar previo a la cirugía de páncreas o la litiasis biliar. Los gramnegativos continúan siendo los microorganismos más frecuentes, especialmente Escherichia coli. Entre los grampositivos cabe destacar a Enterococcus spp. Actualmente, existe controversia acerca de si la presencia de bacteriobilia tiene impacto en la mala evolución de la enfermedad biliar o de los procedimientos quirúrgicos o en las tasas de mortalidad, con complicaciones como infecciones del sitio quirúrgico o bacteriemia. En los pacientes de mayor riesgo, como los inmunosuprimidos o en los que se practica duodenopancreatectomía, los cultivos sistemáticos de bilis, aunque no existan datos clínicos de infección, pueden ser necesarios para iniciar tratamiento antibiótico o para reducir su espectro (AU)

Bile duct is usually sterile, and the isolating of microorganisms (bacteriobilia) has been related to some factors, such as age, biliary drainage before pancreatic surgery or bile duct stones. Gramnegative strains remain the most frequent pathogens, especially Escherichia coli. Among grampositives Enterococcus spp should be mentioned. Currently, there is controversy about whether the presence of bacteriobilia has an impact on unfavorable outcome of biliary disease or surgical procedures or mortality rates, with complications such as surgical site infections or bacteremia. In high-risk patients, such as immunosuppressed or those underwent pancreaticoduodenectomy, bile duct cultures performed routinely, even if there are not clinical data of infection, could be necessary in order to start antibiotic treatment or to reduce its spectrum (AU)

Papel de la bacteriobilia en las complicaciones postoperatorias / Role of bacteriobilia in postoperative complications

Introducción. Actualmente existe controversia respecto al impacto de la positividad de cultivos biliares en la tasa de morbilidad y mortalidad, y en la incidencia de readmisiones en pacientes con enfermedad biliar. El objetivo de este estudio fue evaluar el papel de la bacteriobilia en las infecciones postoperatorias, la mortalidad o el reingreso hospitalario en estos pacientes. Métodos. La información se obtuvo a partir de los cultivos de vía biliar de los pacientes intervenidos en el Hospital Universitario Marqués de Valdecilla (Santander, España) entre enero y diciembre de 2011. Se analizaron los datos clínicos, epidemiológicos y microbiológicos. Los pacientes fueron seguidos durante dos años. Resultados. Se incluyeron 152 pacientes (65% varones). La media de edad fue de 67 años (DE: 15 años). Los diagnósticos más frecuentes fueron colecistitis aguda (79%) y colangitis (8%). Se realizó colecistectomía laparoscópica en el 42% de los pacientes, colecistectomía abierta en el 45% y colecistostomía percutánea en el 8%. La bacteriobilia estaba presente en 83 pacientes (55%). Los microorganismos más frecuentemente aislados fueron Escherichia coli (31%), Enterococcus faecium (13%) y Klebsiella pneumoniae (13%). Los antibióticos iniciales fueron carbapenémicos en 62 pacientes (44%) y piperacilina-tazobactam en 28 pacientes (18%). Hubo 39 infecciones postoperatorias (26%) y 17 pacientes fallecieron durante el ingreso (11%). Se registraron 21 reingresos (14%). La bacteriobilia no fue un predictor estadísticamente significativo de complicaciones o reingreso hospitalario. Conclusiones. Los cultivos biliares intraoperatorios permitieron orientar la terapia antimicrobiana empírica y el tratamiento antibiótico apropiado; sin embargo no hubo correlación entre la bacteriobilia y las infecciones posoperatorias, la duración del ingreso, la mortalidad o los reingresos (AU)

Introduction. At present there is a controversy regarding the impact of positive bile cultures on morbidity and mortality rates, and on the incidence of readmissions in patients with biliar disease. The aim of this study was to evaluate the role of bacteriobilia in postoperatory infections, mortality or readmissions in these patients. Methods. The information was obtained from all patients with bile cultures admitted to Hospital Universitario Marqués de Valdecilla (Santander, Spain) from January to December 2011. Clinical, epidemiological and microbiological data and laboratory findings were analyzed. The patients were followed for two years. Results. One hundred and fifty-two patients (65% men) were included. Mean age was 67 years (SD= 15 years). The most frequent diagnoses were acute cholecystitis (79%) and cholangitis (8%). Laparoscopic cholecystectomy was performed in 42% of patients, open cholecystectomy in 45% and percutaneous cholecystostomy in 8%. Bacteriobilia was present in 83 patients (55%). The most frecuent microorganisms isolated were Escherichia coli (31%), Enterococcus faecium (13%) and Klebsiella pneumoniae (13%). The initial antimicrobial agent was a carbapenem in 62 patients (44%) and piperacillin-tazobactam in 28 (18%). There were 39 postoperative infections (26%), 21 readmissions (14%) and 17 patients died during admission (11%). The presence of microorganisms in bile cultures was not a statistically significant predictor of neither complications nor readmissions. Conclusions. Intra-operative bile cultures would allow guide early appropriate antibiotic treatment use in case of infection, or empiric antimicrobial therapy, however there was no correlation between bacteriobilia and postoperative infections, length of stay, mortality or readmissions (AU)

[Hydatidosis: epidemiological, clinical, diagnostic and therapeutic aspects]. / Hidatidosis: aspectos epidemiológicos, clínicos, diagnósticos y terapéuticos.

Hydatidosis or cystic echinococcosis (CE) is a parasitic zoonosis caused by Echinococcus granulosus. Its life cycle involves dogs, sheep and sometimes other animals. CE has a worldwide distribution, with greater prevalence in temperate zones. In Spain, Castile and León, La Rioja, Navarre, Aragón, and the Mediterranean coast are the areas where it is most commonly diagnosed, although there have also been published cases in other regions, such as Cantabria. Clinical signs and symptoms of EC may be related to the mass effect of the cyst, its superinfection or anaphylactic reactions secondary to its rupture. Because of its slow growth, diagnosis is usually made in adulthood by combining clinical symptoms with imaging and serological tests. There is no universal consensus on the management of CE. Treatment is based mainly on three pillars: medical treatment (mainly albendazole), surgery, and percutaneous drainage. The choice of the most appropriate approach is based on the patient's symptoms and the characteristics of the cysts.

Hidatidosis: aspectos epidemiológicos, clínicos, diagnósticos y terapéuticos / Hydatidosis: epidemiological, clinical, diagnostic and therapeutic aspects

La hidatidosis o equinococosis quística (EQ) es una zoonosis parasitaria causada por Echinococcus granulosus. Su ciclo vital incluye perros, ovejas y otros animales. La EQ tiene distribución mundial, con mayor prevalencia en zonas templadas. En España, Castilla y León, La Rioja, Navarra, Aragón y la costa mediterránea son las áreas donde se diagnostica más frecuentemente, aunque también se han publicado casos en otras regiones, como Cantabria. Los signos y síntomas de la EQ pueden deberse al efecto masa del quiste, su sobreinfección o reacciones de anafilaxia secundarias a su ruptura. Debido a su lento crecimiento, el diagnóstico habitualmente se realiza en la edad adulta, mediante los síntomas clínicos y las pruebas de imagen y serológicas. No hay consenso universal respecto al tratamiento de la EQ. Éste se basa en tres pilares fundamentales: cirugía, drenaje percutáneo y antiparasitarios (habitualmente albendazol). La elección del tratamiento más apropiado se basa en la sintomatología del paciente y las características del quiste (AU)

Hydatidosis or cystic echinococcosis (CE) is a parasitic zoonosis caused by Echinococcus granulosus. Its life cycle involves dogs, sheep and sometimes other animals. CE has a worldwide distribution, with greater prevalence in temperate zones. In Spain, Castile and León, La Rioja, Navarre, Aragón, and the Mediterranean coast are the areas where it is most commonly diagnosed, although there have also been published cases in other regions, such as Cantabria. Clinical signs and symptoms of EC may be related to the mass effect of the cyst, its superinfection or anaphylactic reactions secondary to its rupture. Because of its slow growth, diagnosis is usually made in adulthood by combining clinical symptoms with imaging and serological tests. There is no universal consensus on the management of CE. Treatment is based mainly on three pillars: medical treatment (mainly albendazole), surgery, and percutaneous drainage. The choice of the most appropriate approach is based on the patient’s symptoms and the characteristics of the cysts (AU)

Executive summary. Management of urinary tract infection in solid organ transplant recipients: Consensus statement of the Group for the Study of Infection in Transplant Recipients (GESITRA) of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) and the Spanish Network for Research in Infectious Diseases (REIPI).

Urinary tract infections (UTI) are one of the most common infections in solid organ transplant (SOT) recipients. A systematic review was performed to assess the management of UTI in SOT recipients. Recommendations are provided on the management of asymptomatic bacteriuria, and prophylaxis and treatment of UTI in SOT recipients. The diagnostic-therapeutic management of recurrent UTI and the role of infection in kidney graft rejection or dysfunction are reviewed. Finally, recommendations on antimicrobials and immunosuppressant interactions are also included.

BACKGROUND: Urinary tract infections (UTIs) are one of the most common infections in solid organ transplant (SOT) recipients. METHODS: Experienced SOT researchers and clinicians have developed and implemented this consensus document in support of the optimal management of these patients. A systematic review was conducted, and evidence levels based on the available literature are given for each recommendation. This article was written in accordance with international recommendations on consensus statements and the recommendations of the Appraisal of Guidelines for Research and Evaluation II (AGREE II). RESULTS: Recommendations are provided on the management of asymptomatic bacteriuria, and prophylaxis and treatment of UTI in SOT recipients. The diagnostic-therapeutic management of recurrent UTI and the role of infection in kidney graft rejection or dysfunction are reviewed. Finally, recommendations on antimicrobials and immunosuppressant interactions are also included. CONCLUSIONS: The latest scientific information on UTI in SOT is incorporated in this consensus document.
