RÉSUMÉ

OBJECTIVE: To analyse the susceptibility to ceftolozane-tazobactam and comparators in Enterobacterales and Pseudomonas aeruginosa isolates recovered from intraabdominal (IAI), urinary (UTI), respiratory (RTI) and bloodstream infection (BSI) in the SMART (Study for Monitoring Antimicrobial Resistance Trends) study. METHODS: The susceptibility of 5,351 isolates collected in 11 Spanish hospitals (2016-2018) were analysed (EUCAST-2020 criteria) by broth microdilution and were phenotypically studied for the presence of extended-spectrum beta-lactamases (ESBL). Ceftolozane-tazobactam and/or carbapenem resistant isolates were genetically characterized for ESBL and carbapenemases. RESULTS: Escherichia coli was the most frequent pathogen (49.3% IAI, 54.9% UTI, 16.7% RTI and 50% BSI), followed by Klebsiella pneumoniae (11.9%, 19.1%, 13.1% and 15.4%, respectively). P. aeruginosa was isolated in 9.3%, 5.6%, 32% and 9%, respectively. The frequency of isolates with ESBLs (2016-2017) was: 30.5% K. pneumoniae, 8.6% E. coli, 2.3% Klebsiella oxytoca and 0.7% Proteus mirabilis. Ceftolozane-tazobactam was very active against non-ESBL-(99.3% susceptible) and ESBL-(95.2%) producing E. coli being less active against K. pneumoniae (98% and 43.1%, respectively) isolates. CTX-M-15 was the most prevalent ESBL in E. coli (27.5%) and K. pneumoniae (51.9%) frequently associated with OXA-48-like carbapenemase. Overall, 93% of P. aeruginosa isolates were susceptible to ceftolozane-tazobactam, preserving this activity (>75%) in isolates resistant to other beta-lactams except in those resistant to meropenen or ceftazidime-avibactam. GES-5, PER-1, VIM-1/2 were the most prevalent enzymes in isolates resistant to ceftolozane-tazobactam. CONCLUSIONS: Ceftolozane-tazobactam showed high activity rates against isolates recovered in the SMART study although it was affected in K. pneumoniae and P. aeruginosa isolates with ESBL and/or carbapenemases.

RÉSUMÉ

Objetivo: Establecer recomendaciones para conocer, identificar y manejar las necesidades psicológicas y emocionales de los pacientes con enfermedades inflamatorias crónicas dermatológicas en la práctica clínica habitual. Métodos: En una reunión de grupo nominal con expertos dermatólogos y psicólogos, se realizó una discusión guiada sobre las necesidades psicológicas y emocionales de estos pacientes, cómo abordarlas, y cuáles serían los criterios de derivación apropiados. A partir de todo ello, con la ayuda de un grupo focal de pacientes y de una revisión de la literatura, se preparó un documento matriz con las recomendaciones para su discusión, así como una encuesta tipo Delphi para evaluar el grado de acuerdo con las mismas, que se hizo extensiva a más dermatólogos y psicólogos. Resultados: Se establecieron 10 recomendaciones que podrían resumirse en las siguientes: explore la esfera psicológica de los pacientes con preguntas abiertas tanto en el momento del diagnóstico como durante el curso de la enfermedad. Dele explicaciones claras adaptadas a sus preocupaciones e infórmele de la existencia de asociaciones de pacientes. Explore si existen síntomas de ansiedad y depresión, y si se confirman mediantes una puntuación de 11 o más en la Hospital Anxiety and Depression Scale (HADS), valore una derivación a un especialista en salud mental. En las visitas, genere un clima de confianza, empatice con el paciente, consensúe con él los objetivos y opciones terapéuticas, y motívele para conseguir una buena adherencia. Conclusiones: Estas recomendaciones pueden servir a los profesionales sanitarios para que aborden de forma abierta y natural aspectos psicológicos y emocionales del paciente en la consulta diaria


Objective: To establish recommendations to determine, identify, and manage the psychological and emotional needs of patients with chronic inflammatory skin diseases in clinical practice. Methods: A guided discussion was held at meeting of a nominal group of expert dermatologists and psychologists on the psychological and emotional needs of patients with chronic inflammatory skin diseases, how to manage these cases, and which referral criteria to employ. Based on the results of the discussion, and with the aid of a patient focus group and a review of the literature, a master document was drawn up with recommendations for discussion. A Delphi survey was circulated among a larger group of dermatologists and psychologists to assess the level of agreement with the recommendations. Results: Ten recommendations were established and can be summarized as follows: explore the psychological sphere of the patients with open questions at the time of diagnosis and during the course of the disease; provide patients with clear explanations that address their concerns and inform them of the existence of patient associations; investigate symptoms of anxiety and depression and, if confirmed by means of a Hospital Anxiety and Depression score (HADS) of 11 or greater, consider referral to a mental-health specialist; and, during visits, create a climate of trust, empathize with patients, agree goals and treatment options with them, and motivate them to adhere to those treatments. Conclusions: These recommendations may help health care professionals address psychological and emotional aspects of their patients in daily clinical practice

RÉSUMÉ

OBJECTIVE: Continuous antimicrobial resistance surveillance is recommended by Public Health authorities. We up-dated data from the SMART (Study for Monitoring Antimicrobial Resistance Trends) surveillance study in Spain. METHODS: The antimicrobial susceptibility data and extended-spectrum beta-lactamase (ESBL) production in isolates recovered from intra-abdominal (IAI) (n=1,429) and urinary tract (UTI) (n=937) infections during the 2016- 2017 SMART study in 10 Spanish hospitals were analysed. RESULTS: Escherichia coli was the most frequently microorganism isolated (48.3% and 53.7%) followed by Klebsiella spp. (11.5% and 21.9%) in IAIs and UTIs, respectively. Figures for Pseudomonas aeruginosa were 9.0% and 6.1%, being more frequently recovered from patients with nosocomial infections. Overall, 9.9% (IAI) and 14.0% (UTI) of E. coli, Klebsiella spp. and Proteus mirabilis isolates were ESBL-producers, being Klebsiella pneumoniae (34.5%) from UTI of nosocomial origin the most frequent. ESBL-producers were higher in patients >60 years in both IAIs and UTIs. As in previous years, amikacin (96.3%-100% susceptibility), ertapenem (84.2%-100%) and imipenem (70.3%- 100%) were the most active antimicrobials tested among Enterobacterales species. The activity of amoxicillin-clavulanic, piperacillin-tazobactam, and ciprofloxacin susceptibility was lower, particularly among ESBL-producers. Ertapenem susceptibility (88.9%-100%) was retained in ESBL-E. coli isolates that were resistant to these antimicrobials but decreased (28.6%-100%) in similar isolates of K. pneumoniae. CONCLUSIONS: Continuous antimicrobial resistance surveillance from the SMART study reveals overall maintenance of ESBL-producers in Spain, although with higher presence in isolates from UTIs than from IAIs. Moreover, ertapenem activity was high in E. coli irrespective of ESBL production but decreased in K. pneumoniae, particularly among ESBL-producers.

RÉSUMÉ

OBJECTIVE: The aim of this study was to analyse differences in clinical presentation in patients with early (< 3 years' duration) systemic sclerosis (SSc), comparing three age groups according to disease subsets. METHOD: Cross-sectional analysis of the prospective EULAR Scleroderma Trials and Research database (EUSTAR) was performed. Patients fulfilling preliminary American College of Rheumatology 1980 classification criteria for SSc, with < 3 years from the first non-Raynaud's SSc symptom at first entry, were selected. Patients with < 3 years from the first SSc symptom, including Raynaud's phenomenon, were also analysed. SSc-related variables, including antibodies, SSc subsets, and organ involvement, were examined. Age was categorized into ≤ 30, 31-59, and ≥ 60 years. We performed descriptive and bivariate analyses. RESULTS: The study included 1027 patients: 90% Caucasian, 80% women, and 40% with diffuse disease. In early stages of SSc, younger patients had significantly more anti-Scl-70 antibodies and diffuse disease. With increasing age, we observed more elevation of estimated pulmonary systolic pressure on echocardiography (5%, 13%, and 30%, respectively, in the three age groups), cardiac conduction blocks (6%, 6%, and 15%), and left ventricular diastolic dysfunction (4%, 12%, and 27%). The results were similar for 650 patients with < 3 years from first SSc symptom, including Raynaud's. CONCLUSION: In early stages of SSc, older patients showed data indicating more severe disease with greater cardiac involvement. The diffuse subset was more frequent in the younger subgroup. The identification of such differences may help in selecting appropriate management for individual patients in clinical practice.

RÉSUMÉ

OBJECTIVE: The SMART (Study for Monitoring Antimicrobial Resistance Trends) surveillance study monitors antimicrobial susceptibility and extended spectrum ß-lactamases (ESBLs) in Gram-negative bacilli recovered from intra-abdominal infections (IAI). METHODS: Antimicrobial susceptibility of 5,343 isolates from IAI recovered in 11 centres during the 2011-2015 SMART-Spain program was analysed by standard microdilution (EUCAST criteria) and compared with that from 2002-2010. ESBLs were phenotypically detected. RESULTS: Escherichia coli, the most common isolate, significantly decreased in community acquired IAI (60.9% 2002-2010 vs. 56.1% 2011-2015, P=0.0003). It was followed in prevalence by Klebsiella pneumoniae that increased both in the community (8.9% vs. 10.8%, P=0.016) and nosocomial (9.2% vs. 10.8%, P=0.029) IAI and P. aeruginosa, which significantly increased in community acquired IAI (5.6% vs. 8.0%, P=0.0003). ESBLs were more prevalent in K. pneumoniae (16.3%) than in E. coli (9.5%) of nosocomial origin and were more frequently isolated from elderly patients (>60 years). Considering all Enterobacteriaceae, ertapenem (92.3-100%) and amikacin (95.5%-100%) were the most active antimicrobials. Ertapenem activity, unlike amoxicillin-clavulanate or piperacillin-tazobactam, remained virtually unchanged in ESBL (100%) and non-ESBL (98.8%) E. coli producers. Its activity decreased in ESBL-K. pneumoniae (74.7%) but was higher than that of amoxicillin-clavulanate (14.0%) and piperacillin-tazobactam (24.0%). Interestingly, ertapenem susceptibility was maintained in >60% of ESBL isolates that were resistant to amoxicillin-clavulanate, piperacillin-tazobactam or fluoroquinolones. CONCLUSIONS: SMART-Spain results support current guidelines which include ertapenem as empiric treatment in mild-moderate community-acquired IAI, particularly with ESBL producers. These recommendations will need to be updated with the recently introduction of new antimicrobials.

RÉSUMÉ

BACKGROUND: Alport syndrome is an inherited renal disorder characterized by glomerular basement membrane lesions with hematuria, proteinuria and frequent hearing defects and ocular abnormalities. The disease is associated with mutations in genes encoding α3, α4, or α5 chains of type IV collagen, namely COL4A3 and COL4A4 in chromosome 2 and COL4A5 in chromosome X. In contrast to the well-known X-linked and autosomal recessive phenotypes, there is very little information about the autosomal dominant. In view of the wide spectrum of phenotypes, an exact diagnosis is sometimes difficult to achieve. METHODS: We investigated a Spanish family with variable phenotype of autosomal dominant Alport syndrome using clinical, histological, and genetic analysis. RESULTS: Mutational analysis of COL4A3 and COL4A4 genes showed a novel heterozygous mutation (c. 998G > A; p.G333E) in exon 18 of the COL4A3 gene. Among relatives carrying the novel mutation, the clinical phenotype was variable. Two additional COL4A3 mutations were found, a Pro-Leu substitution in exon 48 (p.P1461L) and a Ser-Cys substitution in exon 49 (p.S1492C), non-pathogenics alone. CONCLUSION: Carriers of p.G333E and p.P1461L or p.S1492C mutations in COL4A3 gene appear to be more severely affected than carriers of only p.G333E mutation, and the clinical findings has an earlier onset. In this way, we could speculate on a synergistic effect of compound heterozygosity that could explain the different phenotype observed in this family.

RÉSUMÉ

OBJECTIVE: To develop recommendations on the evaluation and management procedure in patients undergoing total knee replacement based on best evidence and the experience of a panel of experts. METHODS: A multidisciplinary group of 12 experts was selected that defined the scope, users and the document parts. Three systematic reviews were performed in patients undergoing knee replacement: (i)efficacy and safety of fast-tracks; (ii)efficacy and safety of cognitive interventions in patients with catastrophic pain, and (iii) efficacy and safety of acute post-surgical pain management on post-surgical outcomes. A narrative review was conducted on the evaluation and management of pain sensitization, and about the efficacy and safety of pre-surgical physiotherapy. The experts generated the recommendations and explicative text. The level of agreement was evaluated in a multidisciplinary group of 85 experts with the Delphi technique. The level of evidence was established as well for each recommendation. RESULTS: A total of 20 recommendations were produced. An agreement higher than 80% was reached in all of them. We found the highest agreement on the need for a full discharge report, on providing proper information about the process and on following available guidelines. CONCLUSIONS: There is consensus among professionals involved in the management of patients undergoing total knee replacement, in that it is important to protocolize the replacement process, performing a proper, integrated and coordinated patient evaluation and follow-up, paying special attention to the surgical procedure and postoperative period.

RÉSUMÉ

Even with appropriate clinical management, complicated methicillin-susceptible Staphylococcus aureus (MSSA) catheter-related bacteremia (CRB) is frequent. We investigated the influence of molecular characteristics of MSSA strains on the risk of complicated bacteremia (CB) in MSSA-CRB. A multicenter prospective study was conducted in Spain between 2011 and 2014 on MSSA-CRB. Optimized protocol-guided clinical management was required. CB included endocarditis, septic thrombophlebitis, persistent bacteremia and/or end-organ hematogenous spread. Molecular typing, agr functionality and DNA microarray analysis of virulence factors were performed in all MSSA isolates. Out of 83 MSSA-CRB episodes included, 26 (31.3%) developed CB. MSSA isolates belonged to 16 clonal complexes (CCs), with CC30 (32.5%), CC5 (15.7%) and CC45 (13.3) being the most common. Comparison between MSSA isolates in episodes with or without CB revealed no differences regarding agr type and functionality. However, our results showed that CC15 and the presence of genes like cna, chp and cap8 were associated with the development of CB. The multivariate analysis highlighted that the presence of cna (Hazard ratio 2.9; 95% CI 1.14-7.6) was associated with the development of CB. Our results suggest that particular CCs and specific genes may influence the outcome of MSSA-CRB.

RÉSUMÉ

Bovine tuberculosis (bTB) is usually diagnosed in vivo and ex vivo on the basis of delayed hypersensitivity reactions with a complex pool of antigens named bovine tuberculin (PPDB). The IFN-γ release assay (IGRA) for bTB is a blood-based assay that improves detection of infected cattle at early stages that escape skin testing. Improvements to IFN-γ testing with specific proteins have been performed to increase sensitivity. DosR regulon-related antigens are well known mycobacterial proteins expressed during the non-replicative phases of infection, this has been useful to improve the diagnosis of subclinical forms of TB in suspected individuals. Transcripts of DosR genes mb2054c, mb2057c, and mb2660c have been identified by our group in lymph nodes of IFN-γ test negative cattle. This led us to hypothesize that DosR-related proteins may potentiate the IFN-γ response to PPDB in animals with a false negative IFN-γ test, making evident subclinical infection. Three hundred animals were evaluated by means of IGRA and post-mortem microbiological analysis of tissue samples to validate M. bovis infection. We found that 176 out of 300 animals showed an overall increased OD in complemented IGRA with two purified protein cocktails in comparison to PPDB alone, and were scrutinized for a subclinical infection; thirty percent when PPDB was supplemented with a cocktail of four DosR antigens, and 70% when PPDB was supplemented with a cocktail of six antigens (four DosR and two RD1 antigens). Forty five animals showed a substantial IFN-γ overproduction but remained negative, and 40 animals changed the result to a positive test. Only 18 out of 176 IFN-γ high producing animals were also positive to M. bovis isolation. Fifty seven animals with no visible lesions at slaughter and with a negative IGRA test result contained M. bovis DNA in tissue samples. In conclusion, Mb1762c, Mb2054c, Mb2057c, and Mb2660c have the potential to increase sensitivity of the IFN-γ in vitro test for bTB diagnosis when supplemented to PPDB.

RÉSUMÉ

BACKGROUND: There are substantial differences in accessibility to biological disease modifying antirheumatic drugs (bDMARDs) across countries. The objective of this study was to analyse the impact of patient demographics, disease characteristics and gross domestic product (GDP) on abatacept (ABA) retention in patients with rheumatoid arthritis (RA) treated in clinical practice. METHODS: Data from nine European observational RA cohorts of patients treated with ABA were pooled. Kaplan-Meier analysis was used to compare drug retention across registries. Specific causes of drug retention were investigated using competing risks multivariate Cox regression. RESULTS: A total of 3961 patients treated with ABA, with 6188 patient-years of follow-up, were included. Patients in the different national registries had similar demographic features, but varied in baseline disease characteristics. ABA drug retention differed between countries, with median drug retention rates ranging from 1.2 to more than 6 years. The differences in drug retention were marginally explained by disparities in disease characteristics, while the national GDP per capita was strongly associated with drug retention (correlation coefficient -0.74; p=0.02). CONCLUSIONS: Patient characteristics at ABA initiation vary across Europe, probably reflecting differences in eligibility criteria and prescription patterns. However, the difference in ABA drug retention between countries was not primarily explained by disparities in patient characteristics. Lower ABA retention was observed in countries with a more liberal access to bDMARDs and higher GDP. National differences need to be accounted for when pooling data on treatment with bDMARDs from various countries.

RÉSUMÉ

We aimed to investigate the morphological features of healing of postoperative wounds in the early stages of reparative process in the experiment, depending on the used type of the wound closure. It is proved that the nature and type of the scar depends on the processes that occur in the wound at the early postoperative stage, which in turn greatly affects the form of suture material used. The experiment included 20 male rats, weighing 180-200 g. All rats were anesthetized by a single intraperitoneal injection of sodium thiopental. After the shaving operative field, 2 cm full-thickness incision wound was made on the anterior surface of the abdomen in the longitudinal direction. As suture material for wound closure in the 1st experimental group (10 rats) we used surgical filament "Polyamide 4-0¼. In the 2nd experimental group (10 rats) wounds were closured by using skin glue "Dermabond". According from our experiment, the usage of skin glue creates better conditions for wound healing. Thus, to achieve a more aesthetic scar, we recommend applying skin glue instead of using nodal joints.

RÉSUMÉ

Objetivo: Desarrollar recomendaciones basadas en la mejor evidencia y experiencia sobre el manejo del dolor en pacientes con artrosis de rodilla o cadera e indicación de artroplastia. Métodos: Las recomendaciones se emitieron siguiendo la metodología de grupos nominales. Se seleccionó un grupo director de expertos (5 traumatólogos y un anestesiólogo) que definieron el alcance, usuarios, apartados del documento, posibles recomendaciones, revisiones sistemáticas y se asignaron tareas. Se realizaron 3 revisiones sistemáticas sobre: la eficacia y seguridad de la analgesia prequirúrgica en relación al dolor posquirúrgico; la eficacia y seguridad de la analgesia preventiva, y sobre los factores prequirúrgicos que influyen en el dolor posquirúrgico. Los expertos redactaron los apartados y generaron las recomendaciones correspondientes. El nivel de evidencia y grado de recomendación se clasificaron según el modelo del Center for Evidence Based Medicine de Oxford y el grado de acuerdo por técnica Delphi (2 rondas). El Delphi se amplió a 39 traumatólogos y anestesiólogos. El documento completo circuló entre el grupo director para su última revisión. Resultados: Se generaron 21 recomendaciones. Incluye el manejo farmacológico específico, la evaluación y monitorización de estos pacientes que están en tratamiento, y el tratamiento preventivo del dolor posquirúrgico. Existió consenso mayor del 70% en 19 de ellas. Conclusiones: En el paciente pendiente de artroplastia de cadera o rodilla se debe hacer una correcta evaluación, seguimiento y manejo farmacológico y no farmacológico de los factores que predicen un mal resultado de la intervención, en particular del dolor prequirúrgico. Estas actuaciones pueden mejorar el dolor posquirúrgico y el resultado de la artroplastia (AU)


Objective: To develop recommendations, based on best evidence and experience, on pain management in patients undertaking total knee or hip replacement. Methods: Nominal group methodology was followed. A group of experts was selected (5 orthopedics, 1 anesthesiologist), who defined the scope, users, topics, preliminary recommendations, and 3 systematic reviews: efficacy and safety of pre-surgical analgesia regarding to post-surgical pain, efficacy and safety of pre-emptive analgesia and pre-operative factors of post-operative pain. The level of evidence and grade of recommendation was established using the Oxford Centre for Evidence Based Medicine, and the level of agreement with the Delphi technique (2 rounds). The Delphi was extended to 39 orthopedics and anesthesiologists. The whole document was reviewed by all the experts. Results: A total of 21 recommendations were produced. They include specific pharmacological treatment, as well as the evaluation and monitoring of patients on this treatment, and post-operative pre-emptive treatment. Agreement above 70% was reached in 19 recommendations. Conclusions: In patients undergoing total knee or hip replacement, a proper evaluation, follow-up, pharmacological and non-pharmacological treatment of predictors of poor surgical outcomes should be performed, especially those related to pre-operative pain. This can improve post-operative pain and surgery outcomes (AU)

RÉSUMÉ

Objetivo: Analizar la eficacia y la seguridad de la analgesia preventiva en pacientes que son sometidos a artroplastia de cadera o rodilla por artrosis. Métodos: Se realizó una revisión sistemática: se definió una estrategia de búsqueda bibliográfica sensible en Medline, Embase y Cochrane Library hasta mayo de 2013; se definió la población con los siguientes criterios: pacientes con indicación de artroplastia de cadera y/o rodilla, adultos, dolor moderado a intenso (≥ 4 en la Escala Visual Analógica), la intervención, el uso (eficacia y seguridad) del tratamiento farmacológico (preventivo) próximo a la cirugía. Se incluyeron formulaciones orales, tópicas y parches. Se incluyeron revisiones sistemáticas, metaanálisis, ensayos clínicos y estudios observacionales. Resultados: Se incluyeron 36 artículos de calidad moderada. Incluían pacientes representativos de aquellos a los que se les indica una artroplastia de cadera o rodilla en nuestro país, adultos, con una edad media superior a 50 años, ligera mayor proporción de mujeres y que presentan dolor de moderado a grave (≥ 4 en la Escala Visual Analógica). El dolor posquirúrgico se evaluó sobre todo con la Escala Visual Analógica. Existe mucha variabilidad en cuanto a los fármacos utilizados incluyendo paracetamol, AINE clásicos, AINE selectivos de la Cox-2, opioides, corticoides, antidepresivos, analgésicos para el tratamiento del dolor neuropático y otros como sulfato magnésico, ketamina, nimodipino o clonidina. Todos en general parecen mejorar el dolor posquirúrgico sin presentar acontecimientos adversos graves. Conclusiones: El uso de uno o varios analgésicos en el preoperatorio disminuye el consumo de analgésicos y el dolor en el posoperatorio, al menos el dolor agudo (AU)


Objective: To analyze the efficacy and safety of preventive analgesia in patients undergoing hip or knee arthroplasty due to osteoarthritis. Methods: A systematic literature review was performed, using a defined a sensitive strategy on Medline, Embase and Cochrane Library up to May 2013. The inclusion criteria were: patients undergoing knee and/or hip arthroplasty, adults with moderate or severe pain (≥ 4 on a Visual Analog Scale). The intervention, the use (efficacy and safety) of pharmacological treatment (preventive) close to surgery was recorded. Oral, topical and skin patch drugs were included. Systematic reviews, meta-analysis, controlled trials and observational studies were selected. Results: A total of 36 articles, of moderate quality, were selected. The patients included were representative of those undergoing knee and/or hip arthroplasty in Spain. They had a mean age > 50 years, higher number of women, and reporting moderate to severe pain (≥ 4 on a Visual Analog Scale). Possurgical pain was mainly evaluated with a Visual Analog Scale. A wide variation was found as regards the drugs used in the preventive protocols, including acetaminophen, classic NSAID, Cox-2, opioids, corticosteroids, antidepressants, analgesics for neuropathic pain, as well as others, such as magnesium, ketamine, nimodipine or clonidine. In general, all of them decreased post-surgical pain without severe adverse events. Conclusions: The use or one or more pre-surgical analgesics decreases the use of post-surgical drugs, at least for short term pain (AU)

RÉSUMÉ

BACKGROUND AND PURPOSE: The important pathological consequences of ischaemic heart disease arise from the detrimental effects of the accumulation of long-chain acylcarnitines in the case of acute ischaemia-reperfusion. The aim of this study is to test whether decreasing the L-carnitine content represents an effective strategy to decrease accumulation of long-chain acylcarnitines and to reduce fatty acid oxidation in order to protect the heart against acute ischaemia-reperfusion injury. KEY RESULTS: In this study, we used a novel compound, 4-[ethyl(dimethyl)ammonio]butanoate (Methyl-GBB), which inhibits γ-butyrobetaine dioxygenase (IC50 3 µM) and organic cation transporter 2 (OCTN2, IC50 3 µM), and, in turn, decreases levels of L-carnitine and acylcarnitines in heart tissue. Methyl-GBB reduced both mitochondrial and peroxisomal palmitate oxidation rates by 44 and 53% respectively. In isolated hearts treated with Methyl-GBB, uptake and oxidation rates of labelled palmitate were decreased by 40%, while glucose oxidation was increased twofold. Methyl-GBB (5 or 20 mg·kg(-1)) decreased the infarct size by 45-48%. In vivo pretreatment with Methyl-GBB (20 mg·kg(-1)) attenuated the infarct size by 45% and improved 24 h survival of rats by 20-30%. CONCLUSIONS AND IMPLICATIONS: Reduction of L-carnitine and long-chain acylcarnitine content by the inhibition of OCTN2 represents an effective strategy to protect the heart against ischaemia-reperfusion-induced damage. Methyl-GBB treatment exerted cardioprotective effects and increased survival by limiting long-chain fatty acid oxidation and facilitating glucose metabolism.
