Resumen Introduccion y objetivos La mortalidad en shock cardiogenico (SC), sobre todo en casos refractarios donde se emplean dispositivos de soporte circulatorio mecanico (SCM), es muy elevada. El objetivo es analizar los resultados de un programa de atencion a pacientes en SC tras la implementacion de un equipo multidisciplinario en nuestro centro y la organizacion en red con los hospitales del area. Metodos Estudio observacional retrospectivo de los pacientes atendidos desde septiembre de 2014 a enero de 2019. Se incluyo a los pacientes en SC refractario que precisaron SCM y aquellos que por edad y ausencia de comorbilidades pueden ser candidatos a tratamientos avanzados. El objetivo principal es evaluar la supervivencia hospitalaria. Resultados En total se incluyo a 130 pacientes (69 locales y 61 trasladados). La media de edad era 52 ± 15 anos (el 72% varones). Las etiologias predominantes de SC fueron la insuficiencia cardiaca aguda descompensada (29%), el infarto agudo de miocardio (26%) y el shock tras cardiotomia (25%). En 105 pacientes (81%) se empleo SCM, mayoritariamente oxigenador extracorporeo de membrana (58%). La supervivencia al alta hospitalaria fue del 57% (74 de 130 pacientes). Los principales destinos fueron la recuperacion miocardica y el trasplante cardiaco. La puntuacion SAPS II, el lactato, el infarto como etiologia del SC y la puntuacion de inotropicos y vasoactivos resultaron predictores independientes de mortalidad hospitalaria. Conclusiones La creacion de equipos multidisciplinarios para la atencion de pacientes en SC mayoritariamente refractario y la coordinacion en red con los hospitales del area son factibles y consiguen una supervivencia hospitalaria de mas de la mitad de los pacientes atendidos.

Introduction and objectives Mortality remains high in cardiogenic shock (CS), especially in refractory CS involving the use of mechanical circulatory support (MCS) devices. The aim of this study was to analyze the results of a care program for patients in CS after the creation of a multidisciplinary team in our center and a regional network of hospitals in our area. Methods Observational and retrospective study of patients attended in this program from September 2014 to January 2019. We included patients in refractory CS who required MCS and those who, because of their age and absence of comorbidities, were candidates for advanced therapies. The primary endpoint was survival to discharge. Results A total of 130 patients were included (69 local and 61 transferred patients). The mean age was 52 ± 15 years (72% men). The most frequent causes of CS were acute decompensated heart failure (29%), acute myocardial infarction (26%), and postcardiotomy CS (25%). MCS was used in 105 patients (81%), mostly extracorporeal membrane oxygenation (58%). Survival to discharge was 57% (74 of 130 patients). The most frequent destinations were myocardial recovery and heart transplant. Independent predictors of in-hospital mortality were SAPS II score, lactate level, acute myocardial infarction etiology, and vasoactive-inotropic score. Conclusions The creation of multidisciplinary teams for patients with mainly refractory CS and a regional network is feasible and allows survival to discharge in more than a half of attended patients with CS.

Severely ill COVID-19 patients are at high risk of nosocomial infections. The aim of the study was to describe the characteristics of candidemia during the pre-pandemic period (January 2019-February 2020) compared to the pandemic period (March 2020-September 2021). Antifungal susceptibilities were assessed using the EUCAST E.Def 7.3.2 broth dilution method. Fluconazole-resistant

This study aimed to assess the efficacy of ceftolozane-tazobactam (C/T) for treating infections due to Pseudomonas aeruginosa (P. aeruginosa) in critically ill patients.A multicenter, retrospective and observational study was conducted in critically ill patients receiving different C/T dosages and antibiotic combinations for P. aeruginosa infections. Demographic data, localisation and severity of infection, clinical and microbiological outcome, and mortality were evaluated.Ninety-five patients received C/T for P. aeruginosa serious infections. The main infections were nosocomial pneumonia (56.2%), intra-abdominal infection (10.5%), tracheobronchitis (8.4%), and urinary tract infection (6.3%). Most infections were complicated with sepsis (49.5%) or septic shock (45.3%), and bacteraemia (10.5%). Forty-six episodes were treated with high-dose C/T (3 g every 8 hours) and 38 episodes were treated with standard dosage (1.5 g every 8 hours). Almost half (44.2%) of the patients were treated with C/T monotherapy, and the remaining group received combination therapy with other antibiotics. Sixty-eight (71.6%) patients presented a favourable clinical response. Microbiological eradication was documented in 42.1% (40/95) of the episodes. The global ICU mortality was 36.5%. Univariate analysis showed that 30-day mortality was significantly associated (P0.05) with Charlson Index at ICU admission and the need of life-supporting therapies.C/T appeared to be an effective therapy for severe infections due to P. aeruginosa in critically ill patients. Mortality was mainly related to the severity of the infection. No benefit was observed with high-dose C/T or combination therapy with other antibiotics.

In this outbreak, 12 patients in intensive care units acquired a Chryseobacterium indologenes infection. Cultures from sinkholes and air samples were positive for C. indologenes. After removing wash basins, no new cases appeared. Sinkholes, potentially contaminated, can act as a reservoir for C. indologenes and other microorganisms. Thus, patients and equipment should be protected from sink splashes to avoid contamination.

Background Infections and primary graft dysfunction are devastating complications in the immediate postoperative period following lung transplantation. Nowadays, reliable diagnostic tools are not available. Biomarkers could improve early infection diagnosis. Methods Multicentre prospective observational study that included all centres authorized to perform lung transplantation in Spain. Lung infection and/or primary graft dysfunction presentation during study period (first postoperative week) was determined. Biomarkers were measured on ICU admission and daily till ICU discharge or for the following 6 consecutive postoperative days. Results We included 233 patients. Median PCT levels were significantly lower in patients with no infection than in patients with Infection on all follow up days. PCT levels were similar for PGD grades 1 and 2 and increased significantly in grade 3. CRP levels were similar in all groups, and no significant differences were observed at any study time point. In the absence of PGD grade 3, PCT levels above median (0.50 ng/ml on admission or 1.17 ng/ml on day 1) were significantly associated with more than two- and three-fold increase in the risk of infection (adjusted Odds Ratio 2.37, 95% confidence interval 1.06 to 5.30 and 3.44, 95% confidence interval 1.52 to 7.78, respectively). Conclusions In the absence of severe primary graft dysfunction, procalcitonin can be useful in detecting infections during the first postoperative week. PGD grade 3 significantly increases PCT levels and interferes with the capacity of PCT as a marker of infection. PCT was superior to CRP in the diagnosis of infection during the study period.

One-year survival in lung transplant is around 85%, but this figure has not increased in recent years, in spite of technical improvements.Retrospective, multicenter cohort study. Data from 272 eligible adults with lung transplant were recorded at 7 intensive care units (ICU) in Spain in 2013. The objective was to identify variables that might help to guide future clinical interventions in order to reducethe risk of death in the postoperative period.One patient (0.3%) died in the operating room and 27 (10%) within 90 days. Twenty (7.4%) died within 28 days, after a median of 14 ICU days. Grade 3 pulmonary graft dysfunction was documented in 108 patients, of whom 21 died, compared with 6 out of 163 without pulmonary graft dysfunction (P.001). At ICU admission, non-survivors had significantly lower (P=.03) median PaO2/FiO2 (200mmHg vs 280mmHg), and the difference increased after 24hours (178 vs 297mmHg, P.001). Thirteen required extracorporeal membrane oxygenation, and 7(53.8%) died. A logistic regression model identified pulmonary graft dysfunction (OR: 6.77), donor age60yr (OR: 2.91) and SOFA8 (OR: 2.53) as independent predictors of 90-day mortality. At ICU admission, higher median procalcitonin (1.6 vs 0.6) and lower median PaO2/FiO2 (200 vs 280mmHg) were significantly associated with mortality.Graft dysfunction remains a significant problem in lung transplant. Early ICU interventions in patients with severe hypoxemia or high procalcitonin are crucial in order to lower mortality.

Resumen Antecedentes La perdida del injerto es un problema potencial para la mayoria de los pacientes con trasplante pulmonar. El retrasplante podria suponer una opcion de tratamiento, a pesar de la importante morbilidad y mortalidad asociada a las complicaciones infecciosas. La epidemiologia, asociada a la presentacion clinica y un tratamiento agresivo temprano, siguen constituyendo la base del tratamiento global de la infeccion fungica invasiva. Caso clinico Mujer de 29 anos que recibe un retrasplante unipulmonar izquierdo por bronquiolitis obliterante terminal (BOS), que desarrolla un cuadro de enfermedad fungica invasiva por Candida albicans . La paciente habia recibido profilaxis antifungica con anfotericina B nebulizada y fue tratada con anidulafungina. Ante la sospecha de rechazo agudo del injerto, se administraron bolos de corticoides y tratamiento con plasmaferesis, lo que produjo un fallo multiorganico y su posterior fallecimiento. En los hemocultivos se observaron levaduras, con posterior aislamiento de C. albicans resistente a fluconazol (concentracion minima inhibitoria [CMI] 128 μg/ml), caspofungina (CMI 8 μg/ml) y micafungina (CMI 4 μg/ml) y sensible a anidulafungina (CMI 0,25 μg/ml) y anfotericina B (CMI 0,5 μg/ml). Conclusiones El tratamiento empirico del rechazo agudo del injerto trasplantado mediante bolos de corticoides y tratamiento con plasmaferesis puede suponer un agravamiento de la enfermedad infecciosa subyacente. En pacientes tratados mediante plasmaferesis, podria ser necesario incrementar la dosis habitual de anidulafungina tras la sesion de plasmaferesis. Hasta la fecha, la resistencia a equinocandinas no parece ser un gran problema en el tratamiento de los pacientes con micosis invasivas. Sin embargo, hay un aumento de evidencias de resistencia natural o adquirida, que pueden llevar a un fracaso clinico.

Echinocandins are first-line therapy in critically ill patients with invasive Candida infection (ICI). This study describes our experience with micafungin at Surgical Critical Care Units (SCCUs).A multicenter, observational, retrospective study was performed (12 SCCUs) by reviewing all adult patients receiving 100 mg/24h micafungin for ≥72h during ad-mission (April 2011-July 2013). Patients were divided by ICI category (possible, probable + proven), 24h-SOFA (7, ≥7) and outcome.72 patients were included (29 possible, 13 probable, 30 proven ICI). Forty patients (55.6%) presented SOFA ≥7. Up to 78.0% patients were admitted after urgent surgery (64.3% with SOFA7 vs. 90.3% with SOFA ≥7, p=0.016), and 84.7% presented septic shock. In 66.7% the site of infection was intraabdominal. Forty-nine isolates were recovered (51.0% C. albicans). Treatment was empirical (59.7%), microbiologically directed (19.4%), rescue therapy (15.3%), or anticipated therapy and prophylaxis (2.8% each). Empirical treatment was more frequent (p0.001) in possible versus probable + proven ICI (86.2% vs. 41.9%). Treatment (median) was longer (p=0.002) in probable + proven versus possible ICI (13.0 vs. 8.0 days). Favorable response was 86.1%, without differences by group. Age, blood Candida isolation, rescue therapy, final MELD value and %MELD variation were significantly higher in patients with non-favorable response. In the multivariate analysis (R2=0.246, p0.001) non-favorable response was associated with positive %MELD variations (OR=15.445, 95%CI= 2.529-94.308, p=0.003) and blood Candida isolation (OR=11.409, 95%CI=1.843-70.634, p=0.009).High favorable response was obtained, with blood Candida isolation associated with non-favorable response, in this series with high percentage of patients with intraabdominal ICI, septic shock and microbiological criteria for ICI.

Lung-graft loss is a potential problem for the majority of lung-transplant recipients. Retransplantation could be a treatment option, despite significant morbidity and mortality due to infectious complications. The epidemiology, clinical presentation and early treatment are still the basis of the overall approach to the fungal invasive infection after repeated transplant.This is the case of a 29 year-old woman who underwent a left lung retransplantation due to bronchiolitis obliterans syndrome and developed Candida albicans invasive disease. She received the usual prophylaxis with nebulized liposomal amphotericin B and was also treated with anidulafungin. She received corticosteroid therapy and plasma exchange as acute lung transplant rejection was suspected with subsequent progressive deterioration and death. In the culture of blood samples yeasts were isolated, later identified as C. albicans resistant to fluconazole, caspofungin and micafungin (MCI 128 μg/ml, 8 μg/ml, 4 μg/ml, respectively) and susceptible to anidulafungin and amphotericin B (MCI 0.25 μg/ml, 0.5 μg/ml, respectively).The empirical management of acute transplant rejection with corticosteroid boluses and plasma exchange can help to spread the underlying and undiagnosed fungal infection. It is considered that an increase in the regular dose of anidulafungin is necessary after plasma exchange. To date, fungal echinocandin resistance did not seem to be a major cause for concern in the treatment of patients with invasive mycoses. However, there is increasing evidence of natural and acquired resistance resulting in life-threatening infections and clinical failure.
