Justin J Choi, Matthew W McCarthy
Procalcitonin has emerged as a reliable marker of acute bacterial infection in hospitalized patients and the assay has recently been incorporated into several clinical algorithms to reduce antimicrobial overuse, but its use in patients with end-organ dysfunction is controversial. Areas covered: In this review, the authors examine what is known about procalcitonin testing in patients with organ dysfunction, including those with end-stage renal disease, congestive heart failure, chronic obstructive pulmonary disease, and cirrhosis, and explore how the assay is now being used in the management of non-infectious diseases...

REVIEW
Domenica Federica Briganti, Frank D'Ovidio
Long-term management of end-stage lung disease differs from interstitial lung disease to chronic obstructive pulmonary disease to cystic fibrosis to pulmonary vascular disease. The management includes pharmacological therapy that is disease specific such as antibiotic therapy for cystic fibrosis, antifibrotic drugs in idiopathic pulmonary fibrosis; long-acting beta-agonists, long-acting muscarinic antagonist, and inhaled corticosteroids in chronic obstructive pulmonary disease; and vasodilators in pulmonary arterial hypertension...

BACKGROUND AND AIMS: Pulmonary hypertension is common in patients with end-stage renal disease, and portends a poor prognosis. There are little data in this population, and previous studies have not evaluated quantitative changes in hemodynamics over time while on maintenance dialysis. This study sought to estimate changes in pulmonary artery systolic pressure (PASP) and right ventricular function over time, and to predict PASP change using clinical variables routinely available at time of initial measurement, in patients on maintenance dialysis...

BACKGROUND: The risk of cancer is increased and affects survival after lung transplantation (LTx), but has not been well characterized in COPD. We aimed to evaluate the incidence and prognosis of cancer following LTx for COPD. METHODS: A prospective, population-based study of patients undergoing LTx for end-stage COPD at the two transplantation centers in Sweden between 1990-2013, with follow-up for incident cancer and death, using national registers. The excess risk of cancer was calculated as standardized incidence ratios compared with the general population matched for age, sex, and calendar year...

Background: Middle East respiratory syndrome coronavirus (MERS-CoV) causes pneumonia with a relatively high case fatality rate in humans. Smokers and chronic obstructive pulmonary disease (COPD) patients have been reported to be more susceptible to MERS-CoV infection. Here, we determined the expression of MERS-CoV receptor, dipeptidyl peptidase IV (DPP4), in lung tissues of smokers without airflow limitation and COPD patients in comparison to non-smoking individuals (never-smokers). Methods: DPP4 expression was measured in lung tissue of lung resection specimens of never-smokers, smokers without airflow limitation, COPD GOLD stage II patients and in lung explants of end-stage COPD patients...

PURPOSE OF REVIEW: The aim of the review was to explore patient and family caregiver perspectives on key issues for ensuring quality of end-of-life care for people with chronic obstructive pulmonary disease (COPD). The growing evidence on the value of specialist palliative care services demonstrates significant improvements in treatments and provisions; however, much of the literature is generic in nature or centred on people with a cancer diagnosis. In this review, we examine the literature to ascertain the views and needs of patients and carers affected by advanced COPD, a highly debilitating condition that can have a profoundly negative impact on the quality of end-of-life experience...

Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality and morbidity worldwide, with high and growing prevalence. Its underdiagnosis and hence under-treatment is a general feature across all countries. This is particularly true for the mild or early stages of the disease, when symptoms do not yet interfere with daily living activities and both patients and doctors are likely to underestimate the presence of the disease. A diagnosis of COPD requires spirometry in subjects with a history of exposure to known risk factors and symptoms...

BACKGROUND: Patients with mild or moderate chronic obstructive pulmonary disease (COPD) rarely receive medications, because they have few symptoms. We hypothesized that long-term use of tiotropium would improve lung function and ameliorate the decline in lung function in patients with mild or moderate COPD. METHODS: In a multicenter, randomized, double-blind, placebo-controlled trial that was conducted in China, we randomly assigned 841 patients with COPD of Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage 1 (mild) or 2 (moderate) severity to receive a once-daily inhaled dose (18 μg) of tiotropium (419 patients) or matching placebo (422) for 2 years...

INTRODUCTION: Dialysis patients aged ≥70 years derive improved life expectancy through kidney transplantation compared to their waitlisted counterparts, but guidelines are not clear about how to identify appropriate transplantation candidates. We developed a clinical prediction score to identify elderly dialysis patients with expected 5-year survival appropriate for kidney transplantation (>5 years). METHODS: Incident dialysis patients in 2006-2009 aged ≥70 were identified from the United States Renal Data System database and divided into derivation and validation cohorts...

The benefit of statin therapy in patients with advanced chronic kidney disease remains uncertain. Randomized trials have questioned the efficacy of the drug in improving outcomes for on-dialysis populations, and many patients with end-stage renal disease are not currently taking statins. This study aimed to investigate the impact of statin use on survival of patients with vascular access performed at a vascular center for chronic dialysis. Consecutive end-stage renal disease patients admitted for vascular access surgery in 2006 to 2013 were reviewed...

Chronic obstructive pulmonary disease (COPD) is characterized in the later stages by acute exacerbations that often require hospitalization. Pulmonary rehabilitation is recommended for patients with COPD to aid symptom control, improve quality of life and increase physical activity. We have previously reported a large intervention trial commenced during a hospital admission. The aim of this sub-study was to evaluate the patients' experiences of discharge following the hospitalization for an acute exacerbation of COPD...

The incidence of acute kidney injury (AKI) is high in the elderly, who comprise an ever-growing segment of the population. Elderly patients pose a different set of diagnostic and therapeutic challenge owing to their associated comorbidities. AKI in the elderly is associated with an increased risk of mortality, morbidity, prolonged length of stay, and progression to chronic kidney disease. Data regarding the clinical profile of AKI in the elderly from the South Indian population are limited. Hence, we present this analysis of the etiological and prognostic factors associated with AKI in elderly population from South India...

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease in which the amount of emphysema and airway disease may be very different between individuals, even in end-stage disease. Emphysema formation may be linked to the involvement of the small pulmonary vessels. The NAPDH oxidase (Nox) family is emerging as a key disease-related factor in vascular diseases, but currently its role in hypoxia-induced pulmonary remodelling in COPD remains unclear.Here we investigate the role of p22phox, a regulatory subunit of Nox, in COPD lungs, hypoxic pulmonary vasoconstriction (HPV), hypoxia-induced pulmonary vascular remodelling and pulmonary hypertension...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a consistently progressive, ultimately fatal disease for which no treatment exists capable of either reversing or even interrupting its course. It afflicts more than 5% of the population in many countries, and it accordingly represents the third most frequent cause of death in the US, where it accounts for more than 600 billion in health care costs, morbidity, and mortality. Adipose tissue contains within its stromal compartment a high abundance of adipose stem/stromal cells (ASCs), which can be readily separated from the adipocyte population by methods which require less than 2 h of processing time and yield a concentrated cellular preparation termed the stromal vascular fraction (SVF)...
