Multinational case-control study of risk factors for the development of late invasive pulmonary aspergillosis following kidney transplantation.

Objectives: To assess the risk factors for development of late-onset invasive pulmonary aspergillosis (IPA) after kidney transplantation (KT).

Methods: We performed a multinational case-control study that retrospectively recruited 112 KT recipients diagnosed with IPA between 2000 and 2013. Controls were matched (1:1 ratio) by centre and date of transplantation.

Environmental Factors as Key Determinants for Visceral Leishmaniasis in Solid Organ Transplant Recipients, Madrid, Spain.

During a visceral leishmaniasis outbreak in an area of Madrid, Spain, the incidence of disease among solid organ transplant recipients was 10.3% (7/68). Being a black person from sub-Saharan Africa, undergoing transplantation during the outbreak, and residing <1,000 m from the epidemic focus were risk factors for posttransplant visceral leishmaniasis.

Pathogen-related factors affecting outcome of catheter-related bacteremia due to methicillin-susceptible Staphylococcus aureus in a Spanish multicenter study.

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.

High vancomycin MICs predict the development of infective endocarditis in patients with catheter-related bacteraemia due to methicillin-resistant Staphylococcus aureus.

Background: It has been suggested that there is an increased risk of treatment failure in episodes of MRSA bloodstream infection (BSI) caused by strains with high vancomycin MICs. However, it is unknown if this phenomenon may also act as a risk factor for the development of infective endocarditis (IE).

Methods: We analysed 207 episodes of catheter-related (CR)-BSI recruited from June 2008 to December 2009 within a prospective study on MRSA BSI in 21 Spanish hospitals.

Ventilator-associated pneumonia by methicillin-susceptible Staphylococcus aureus: do minimum inhibitory concentrations to vancomycin and daptomycin matter?

The use of vancomycin minimum inhibitory concentration (MIC) as an outcome predictor in patients with methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia has become an important topic for debate in the last few years. Given these previous results, we decided to investigate whether MICs to vancomycin or daptomycin had any effect on the evolution of patients with ventilator-associated pneumonia (VAP) due to MSSA. An observational, retrospective, multicenter study was conducted among patients with MSSA VAP.

Detection of cytomegalovirus drug resistance mutations in solid organ transplant recipients with suspected resistance.

Background: Current guidelines recommend that treatment of resistant cytomegalovirus (CMV) in solid organ transplant (SOT) recipients must be based on genotypic analysis. However, this recommendation is not systematically followed.

Objectives: To assess the presence of mutations associated with CMV resistance in SOT recipients with suspected resistance, their associated risk factors and the clinical impact of resistance.

Cost-Utility of Group Acceptance and Commitment Therapy for Fibromyalgia Versus Recommended Drugs: An Economic Analysis Alongside a 6-Month Randomized Controlled Trial Conducted in Spain (EFFIGACT Study).

Unlabelled: The aim of this study was to analyze the cost utility of a group-based form of acceptance and commitment therapy (GACT) in patients with fibromyalgia (FM) compared with patients receiving recommended pharmacological treatment (RPT) or on a waiting list (WL). The data were derived from a previously published study, a randomized controlled trial that focused on clinical outcomes. Health economic outcomes included health-related quality of life and health care use at baseline and at 6-month follow-up using the EuroQoL and the Client Service Receipt Inventory, respectively.

Echinocandins Compared to Fluconazole for Candidemia of a Urinary Tract Source: A Propensity Score Analysis.

Background: Whether echinocandins could be used to treat candidemia of a urinary tract source (CUTS) is unknown. We aimed to provide current epidemiological information of CUTS and to compare echinocandin to fluconazole treatment on CUTS outcomes.

Methods: A multicenter study of adult patients with candidemia was conducted in 9 hospitals.

DNA damage response inhibition at dysfunctional telomeres by modulation of telomeric DNA damage response RNAs.

The DNA damage response (DDR) is a set of cellular events that follows the generation of DNA damage. Recently, site-specific small non-coding RNAs, also termed DNA damage response RNAs (DDRNAs), have been shown to play a role in DDR signalling and DNA repair. Dysfunctional telomeres activate DDR in ageing, cancer and an increasing number of identified pathological conditions.

Impact of fluconazole susceptibility on the outcome of patients with candidaemia: data from a population-based surveillance.

Objectives: The clinical correlation of fluconazole antifungal susceptibility testing (AST) for Candida isolates and its integration with pharmacokinetics/pharmacodynamics (PK/PD) parameters is unclear. We analysed the impact of fluconazole minimum inhibitory concentration (MIC) values, 24-hour area under the concentration-time curve (AUC) and AUC/MIC ratio on the outcome of candidemic patients.

Methods: We included 257 episodes of candidaemia treated with fluconazole monotherapy for ≥72 hours from a population-based surveillance conducted in 29 hospitals (CANDIPOP Project).

Serum sCD30: A promising biomarker for predicting the risk of bacterial infection after kidney transplantation.

Background: The transmembrane glycoprotein CD30 contributes to regulate the balance between Th and Th responses. Previous studies have reported conflicting results on the utility of its soluble form (sCD30) to predict post-transplant infection.

Methods: Serum sCD30 was measured by a commercial ELISA assay at baseline and post-transplant months 1, 3, and 6 in 100 kidney transplant (KT) recipients (279 monitoring points).

Risk factors for bacteremia in urinary tract infections attended in the emergency department.

Urinary tract infections (UTI) are common in emergency departments (ED), and at least 15% of them are bacteremic. However, there are few data on how to predict which patients are at high risk of developing bacteremic UTI (b-UTI). We performed a retrospective observational cohort study including patients diagnosed with UTI who were admitted to the ED of a tertiary-care hospital in Spain.

Tuberculosis and Transplantation.

Mycobacterium tuberculosis is a major opportunistic pathogen in transplant recipients. Compared to that in the general population, the frequency of tuberculosis (TB) is 10 to 40 times higher in hematopoietic stem cell transplant (HSCT) recipients and 20 to 74 times higher in solid-organ transplant (SOT) recipients. Transplant recipients with TB are also more likely to develop disseminated disease, have longer time to definitive diagnosis, require more invasive diagnostic procedures, and experience greater anti-TB treatment-related toxicity than the general population.

Complement C3F allotype synthesized by liver recipient modifies transplantation outcome independently from donor hepatic C3.

Complement component 3 (C3) presents both slow (C3S) and fast (C3F) variants, which can be locally produced and activated by immune system cells. We studied C3 recipient variants in 483 liver transplant patients by RT-PCR-HRM to determine their effect on graft outcome during the first year post-transplantation. Allograft survival was significantly decreased in C3FF recipients (C3SS 95% vs C3FS 91% vs C3FF 83%; P=.

Clinical Presentation and Determinants of Mortality of Invasive Pulmonary Aspergillosis in Kidney Transplant Recipients: A Multinational Cohort Study.

The prognostic factors and optimal therapy for invasive pulmonary aspergillosis (IPA) after kidney transplantation (KT) remain poorly studied. We included in this multinational retrospective study 112 recipients diagnosed with probable (75.0% of cases) or proven (25.

Factors associated with and impact of pain persistence in Asian patients with depression: a 3-month, prospective observational study.

Objective: We investigated the depression outcomes and the factors associated with pain persistence in Asian patients treated for major depressive disorder (MDD).

Methods: This observational study enrolled 909 Asian adult inpatients and outpatients. The presence or absence of painful physical symptoms and severity of depression were assessed at baseline and after three months of treatment.

Experience with miltefosine for persistent or relapsing visceral leishmaniasis in solid organ transplant recipients: A case series from Spain.

The incidence of visceral leishmaniasis (VL) after solid organ transplantation (SOT) is increasing. The optimal therapy for post-transplant VL remains unclear, as relapses after liposomal amphotericin B (L-AmB) are common. Miltefosine has been shown to be effective for treating VL in immunocompetent patients, although data in the specific population of SOT recipients are lacking.

Role of mTOR inhibitors for the control of viral infection in solid organ transplant recipients.

Appropriate post-transplant immunosuppressive regimens that avoid acute rejection, while reducing risk of viral reactivation, have been sought, but remain a chimera. Recent evidence suggesting potential regulatory and antiviral effects of mammalian target of rapamycin inhibitors (mTORi) is of great interest. Although the concept of an immunosuppressive drug with antiviral properties is not new, little effort has been made to put the evidence together to assess the management of immunosuppressive therapy in the presence of a viral infection.

Common Genetic Polymorphisms within NFκB-Related Genes and the Risk of Developing Invasive Aspergillosis.

Invasive Aspergillosis (IA) is an opportunistic infection caused by Aspergillus, a ubiquitously present airborne pathogenic mold. A growing number of studies suggest a major host genetic component in disease susceptibility. Here, we evaluated whether 14 single-nucleotide polymorphisms within NFκB1, NFκB2, RelA, RelB, Rel, and IRF4 genes influence the risk of IA in a population of 834 high-risk patients (157 IA and 677 non-IA) recruited through a collaborative effort involving the aspBIOmics consortium and four European clinical institutions.

Fungemia due to rare opportunistic yeasts: data from a population-based surveillance in Spain.

Fungemia due to rare yeasts constitutes an emerging but poorly investigated condition. Data on risk factors, clinical features, therapy, and outcome of episodes of fungemia due to rare (non-Candida, non-Cryptococcus) yeasts were analyzed in a population-based surveillance program conducted in 29 Spanish hospitals between May 2010 and April 2011. Species identification (DNA sequencing) and antifungal susceptibility testing (EUCAST and CLSI methods) were centrally performed.
