BACKGROUND: Real use of lung (LT) and heart-lung (HLT) transplantation in pulmonary arterial hypertension (PAH) is unknown. The objectives were to describe the indication of these procedures on PAH treatment in a national cohort of PAH patients, and to analyze the potential improvement of its indication in severe patients. METHODS: Eligibility for LT/HLT was assessed for each deceased patient. Incident patients from REHAP diagnosed between January 2007 and March 2015 and considered eligible for LT/HLT were grouped as follows: those who finally underwent transplantation (LTP) and those who died (D-Non-LT)...

We report the successful use of ceftolozane/tazobactam (C/T) to treat a pulmonary exacerbation in a 35 year old female, post lung transplant, with cystic fibrosis (CF), malnutrition, chronic kidney disease, and multi-drug resistant Pseudomonas aeruginosa infection (MDR PSA). Given the complexity of the clinical profile, we measured drug levels of C/T during treatment of her current exacerbation to determine pharmacokinetics. The patient achieved an estimated ceftolozane peak of 174.1 μg/mL and trough of 9...

Chronic obstructive pulmonary disease (COPD) is a major global cause of morbidity and mortality, projected to become the 3rd cause of disease mortality worldwide by 2020. COPD is characterized by persistent and not fully reversible airflow limitation that is usually progressive and is associated with an abnormal chronic inflammatory response of the lung to noxious agents including cigarette smoke. Currently available therapeutic strategies aim to ease COPD symptoms but cannot prevent its progress or regenerate physiological lung structure or function...

Mycobacterium tuberculosis (MTB) can disseminate to extra-pulmonary organs, particularly in severely immunosuppressed patients. Confirmation of active MTB infection is often difficult in subjects with contraindication for invasive procedures. We herein report a case of disseminated MTB infection after hematopoietic stem cell transplantation. Circulating cell free DNA of the patient showed positive amplification for a MTB complex specific sequence using digital PCR technique. MTB infection could be confirmed with positive acid fast stain and approved quantitative PCR assay using the liver tissue obtained at an autopsy...

BACKGROUND: Continuation of empirical antimicrobial therapy (EAT) for febrile neutropenia in patients with haematological malignancies until neutrophil recovery could prolong the therapy unnecessarily. We aimed to establish whether EAT discontinuation driven by a clinical approach regardless of neutrophil recovery would optimise the duration of therapy. METHODS: We did an investigator-driven, superiority, open-label, randomised, controlled phase 4 clinical trial in six academic hospitals in Spain...

BACKGROUND The incidence of incisional hernia following renal transplantation is 1.1% to 3.8%. The risk factors are immunosuppressive medications, impaired tissue quality, neuromuscular trauma due to the operation, and denervation. The incidence has been decreasing based on the shift from hockey-stick incision method to inguinal oblique incision method. The aim of this study was to minimize the development of incisional hernias due to renal transplantation. MATERIAL AND METHODS Twenty-four patients who underwent renal transplantation in 2015-2017 were retrospectively examined...

Lung transplantation remains a viable option for patients with endstage pulmonary disease. Despite removing the affected organ and replacing both lungs, the risk of lung malignancies still exists. Regardless of the mode of entry, lung cancer affects the prognosis in these patients and diligence is required.

BACKGROUND: Tacrolimus is metabolized by members of the cytochrome p450 3A subfamily, and its bioavailability depends also on P-glycoprotein. We have observed that some patients admitted for infection presented with increased tacrolimus trough levels (TLs). The aim of the study was to assess the impact of infection on tacrolimus TLs and to determine the factors involved in TL fluctuations. METHODS: This retrospective cohort study included patients transplanted with a kidney between 2009 and 2011 who were hospitalized for an acute infection...

Living kidney donor (LKD) transplantation is an important alternative for the end-stage renal disease population and is preferred due to superior outcomes when compared with dialysis or deceased donor transplantation. LKD evaluation includes a computed tomography angiogram (CTA) for assessment of renal and renovascular anatomy. Incidental nonrenal findings are frequently noted during the CTAs, and these may have variable clinical significance. These incidental findings lead to further testing, procedures, and referrals, which incur additional cost...

Herein, we report the case of a 44-year-old female with end-stage renal disease on hemodialysis. She was admitted to our hospital to evaluate if she was eligible for a kidney transplant. Transthoracic echocardiography showed a markedly dilated coronary sinus and an unexpected finding of increased right ventriculoatrial gradient. A saline contrast echocardiography to confirm the presence of persistent left superior vena cava (PLSVC) was not performed because of arteriovenous fistula (FAV) for hemodialysis on the left forearm...

Acute right heart failure in chronic precapillary pulmonary hypertension is characterised by a rapidly progressive syndrome with systemic congestion resulting from impaired right ventricular filling and/or reduced right ventricular flow output. This clinical picture results from an imbalance between the afterload imposed on the right ventricle and its adaptation capacity. Acute decompensated pulmonary hypertension is associated with a very poor prognosis in the short term. Despite its major impact on survival, its optimal management remains very challenging for specialised centres, without specific recommendations...

Pulmonary hypertension is a critical problem in infants with bronchopulmonary dysplasia. This study determined the therapeutic effects of human mesenchymal stem cells (MSCs) on pulmonary hypertension in an animal model. Pregnant Sprague-Dawley rats were intraperitoneally injected with lipopolysaccharide (LPS, 0.5 mg/kg/day) on gestational days 20 and 21. The pups were randomly assigned to two treatment conditions: room air (RA) or an O2-enriched atmosphere. On postnatal day 5, they were intratracheally transplanted with human MSCs (3 × 10(5) and 1 × 10(6) cells) in 0...

PURPOSE: Bronchiolitis obliterans syndrome after lung transplantation (LTx) manifests as a sustained decline in forced expiratory volume in the first second (FEV1). Quantitative computed tomography (QCT) metrics may predict FEV1 better than semiquantitative scores (SQSs), and the transplanted lung may provide better information than the native lung in unilateral LTx. MATERIALS AND METHODS: Paired inspiratory-expiratory CT scans and pulmonary function testing of 178 LTx patients were analyzed retrospectively...
