Evaluation of Two Different CMV-Immunoglobulin Regimens for Combined CMV Prophylaxis in High-Risk Patients following Lung Transplant.

Background: The clinical benefits of the common off-label use of cytomegalovirus (CMV)-specific immunoglobulin (CMV-Ig) combined with antivirals in organ transplantation have not been previously assessed. The objective was to compare the risk of CMV infection and other post-transplantation outcomes between two CMV-Ig prophylaxis regimens in lung transplant recipients; Methods: Retrospective study of 124 donor CMV positive/recipient negative (D+/R-) patients receiving preventive ganciclovir/valganciclovir for 12 months, of whom 62 received adjunctive CMV-Ig as per label indication (short regimen [SR-Ig]; i.e.

Gastroesophageal Reflux and Esophageal Motility Disorder After Lung Transplant: Influence on the Transplanted Graft.

Background: Esophageal pathology has been identified as a bad prognostic factor in lung transplantation (LTx). This study aims to assess the esophageal disorders present post-LTx, under treatment with proton pump inhibitors, and their putative impact on the graft.

Methods: Prospective, observational study of LTx patients.

COVID-19 in transplant recipients: The Spanish experience.

We report the nationwide experience with solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) recipients diagnosed with coronavirus disease 2019 (COVID-19) in Spain until 13 July 2020. We compiled information for 778 (423 kidney, 113 HSCT, 110 liver, 69 heart, 54 lung, 8 pancreas, 1 multivisceral) recipients. Median age at diagnosis was 61 years (interquartile range [IQR]: 52-70), and 66% were male.

Tuberculosis Following Lung Transplantation. A 27-Year Spanish Multicenter Experience. Incidence, Presentation, Prevention and Treatment with Rifampicin.

Background: Tuberculosis (TB) represents a diagnostic and therapeutic challenge for solid organ transplant recipients, particularly after lung transplant (LT). Our aim was to determine the impact of TB in LT patients in Spain, considering prevalence, clinical presentation, prevention and therapeutic management. In addition, differences in outcome between rifampicin (RIF) versus non-RIF containing regimens were analyzed.

Expression profiling of chromatin-modifying enzymes and global DNA methylation in CD4+ T cells from patients with chronic HIV infection at different HIV control and progression states.

Background: Integration of human immunodeficiency virus type 1 (HIV-1) into the host genome causes global disruption of the chromatin environment. The abundance level of various chromatin-modifying enzymes produces these alterations and affects both the provirus and cellular gene expression. Here, we investigated potential changes in enzyme expression and global DNA methylation in chronically infected individuals with HIV-1 and compared these changes with non-HIV infected individuals.

Short Communication: p21/CDKN1A Expression Shows Broad Interindividual Diversity in a Subset of HIV-1 Elite Controllers.

The p21/CDKN1A protein has been described in vitro as well as in a small subset of patients as a restriction factor for HIV infection. We evaluated p21/CDKN1A mRNA expression on CD4(+) T cells from HIV-infected individuals with two outcomes (18 elite controllers and 28 viremic progressors). Our results show broad interindividual variation in this factor, which is unrelated to the patient's phenotype.

Oki stenting for anastomotic bronchomalacia in lung transplantation.

Anastomotic airway complications are a frequent cause of disease in lung transplantation. However, there is no consensus on the type of treatment to be performed with prosthetic devices. While some recent gadgets such as the Oki stent have been proposed for main right bronchus stenosis, there are no reports of stenting using this prosthesis in cases where the main complication is malacia rather than stenosis.

Point-of-care system for detection of Mycobacterium tuberculosis and rifampin resistance in sputum samples.

Early detection of Mycobacterium tuberculosis complex (MTBC) and markers conveying drug resistance can have a beneficial impact on preventive public health actions. We describe here a new molecular point-of-care (POC) system, the Genedrive, which is based on simple sample preparation combined with PCR to detect MTBC and simultaneously detect mutation markers in the rpoB gene directly from raw sputum sample. Hybridization probes were used to detect the presence of the key mutations in codons 516, 526, and 531 of the rpoB gene.

The Spanish Lung Transplant Registry: first report of results (2006-2010).

The Spanish Lung Transplant Registry (SLTR) began its activities in 2006 with the participation of all the lung transplantation (LT) groups with active programs in Spain. This report presents for the first time an overall description and results of the patients who received lung transplants in Spain from 2006 to 2010. LT activity has grown progressively, and in this time period 951 adults and 31 children underwent lung transplantation.

Development of a non-heart-beating lung donor program with «Bithermia Preservation», and results after one year of clinical experience.

The number of lung transplantations that are performed in Spain continues to grow, with 235 transplant recipients 2010. Non-heart-beating donations have contributed to this upward progression. Our Lung Transplant Unit began its activity in October 2008 and during these last three years 97% of the transplant interventions performed have been successful.

Guidelines for the selection of lung transplantation candidates.

The present guidelines have been prepared with the consensus of at least one representative of each of the hospitals with lung transplantation programs in Spain. In addition, prior to their publication, these guidelines have been reviewed by a group of prominent reviewers who are recognized for their professional experience in the field of lung transplantation. Within the following pages, the reader will find the selection criteria for lung transplantation candidates, when and how to remit a patient to a transplantation center and, lastly, when to add the patient to the waiting list.

Nebulized liposomal amphotericin B prophylaxis for Aspergillus infection in lung transplantation: pharmacokinetics and safety.

Background: The main problem with using nebulized liposomal amphotericin (n-LAB) as prophylaxis for Aspergillus infection after lung transplantation is the lack of knowledge of its pharmacokinetics and its possible adverse effects. The aim of this study was to measure post-inhalation amphotericin B concentration in the respiratory tract and serum of lung transplant patients and assess the effects of n-LAB on respiratory function.

Methods: Thirty-two consecutive bronchoscopies were performed on 27 lung transplant patients at two hospitals.

[Clinical and functional characteristics of patients prior to lung transplantation: report of experience at the Clínica Puerta de Hierro].

Objective: The time at which lung transplantation is indicated is determined by clinical and functional criteria that vary according to the particular disease. The aim of our study was to present the criteria according to which patients were placed on waiting lists for lung transplantation in our hospital.

Patients And Methods: We analyzed retrospectively the clinical characteristics, lung function, heart function, and 6-minute walk test results of patients who had received a lung transplant in our hospital from January 2002 through September 2005.

[Is endoscopic treatment of bronchopleural fistula useful?].

Objective: New endoscopic techniques have been developed as an alternative to surgical treatment of bronchopleural fistula. The objective of this study was to analyze our experience with endoscopic treatment of such fistulas.

Material And Methods: We conducted a retrospective study of patients with bronchopleural fistula diagnosed by fiberoptic bronchoscopy.
