The diagnosis and management of respiratory tract fungal infection in cystic fibrosis: A UK survey of current practice.

Med Mycol. 2018 Mar 15;:

Authors: Boyle M, Moore JE, Whitehouse JL, Bilton D, Downey DG

Abstract
Aspergillus fumigatus is commonly found in the airways of patients with cystic fibrosis (CF), and allergic bronchopulmonary aspergillosis (ABPA) is the most recognized associated clinical condition. However, accurate diagnosis remains challenging, and there is a paucity of clinical trials to guide clinical management of fungal disease. The aim of this survey was to assess the variability in current practice across the UK in diagnosis and management of fungal lung disease in CF patients. A 21 question anonymous online survey was sent to 94 paediatric and adult CF consultants in the UK. The response rate was 60.6% (32 adult physicians, 25 pediatricians) with 55 full and 2 partially completed surveys. For a first diagnosis of ABPA 20 (35.1%) treat with prednisolone alone, 38 (66.7%) use prednisolone with itraconazole and 2 (3.5%) choose voriconazole. Only 5 (8.8%) treat with prednisolone alone for a 1st relapse, 33 (58%) used prednisolone with itraconazole. To reduce treatment, 21 (36.8%) decrease steroids to zero over time and maintain azole therapy, 18 (31.6%) stop the azole and steroid after a fixed time, and 5 (8.8%) stop the azole after a fixed time and maintain a small steroid dose. Thirty-eight (66.7%) respondents believe Aspergillus colonization of the airway can cause clinical deterioration, and 37 (66.1%) would treat this. Scedosporium apiospermum infection has been diagnosed and treated by 35 (61.4%) of respondents. Results of this survey highlight the variance in clinical practice and the limited evidence available to guide management of fungal infection in CF.

Cost(s) of caring for patients with cystic fibrosis.

Curr Opin Pediatr. 2018 Mar 16;:

Authors: Orenstein DM, Abood RN

Abstract
PURPOSE OF REVIEW: Cystic fibrosis (CF) has received a lot of attention in the past few years because of increased longevity and the emergence of ground-breaking new drugs targeting the molecular and cellular defects, making a huge clinical difference, and - not incidentally - carrying massive price tags. The prices of these new drugs make the question of overall costs of CF care highly relevant.
RECENT FINDINGS: This article reviews recent developments in CF science and treatment, and highlights areas that contribute to costs of CF care, emphasizing how these costs have increased.
SUMMARY: This article should help the pediatrician stay abreast of high points of CF care, with an awareness of the factors that wield the biggest influence on overall costs, to patients, families and the US healthcare system.

Novel endoscope with increased depth of field for imaging human nasal tissue by microscopic optical coherence tomography.

Biomed Opt Express. 2018 Feb 01;9(2):636-647

Authors: Schulz-Hildebrandt H, Pieper M, Stehmar C, Ahrens M, Idel C, Wollenberg B, König P, Hüttmann G

Abstract
Intravital microscopy (IVM) offers the opportunity to visualize static and dynamic changes of tissue on a cellular level. It is a valuable tool in research and may considerably improve clinical diagnosis. In contrast to confocal and non-linear microscopy, optical coherence tomography (OCT) with microscopic resolution (mOCT) provides intrinsically cross-sectional imaging. Changing focus position is not needed, which simplifies especially endoscopic imaging. For in-vivo imaging, here we are presenting endo-microscopic OCT (emOCT). A graded-index-lens (GRIN) based 2.75 mm outer diameter rigid endoscope is providing 1.5 - 2 µm nearly isotropic resolution over an extended field of depth. Spherical and chromatic aberrations are used to elongate the focus length. Simulation of the OCT image formation, suggests a better overall image quality in this range compared to a focused Gaussian beam. Total imaging depth at a reduced sensitivity and lateral resolution is more than 200 µm. Using a frame rate of 80 Hz cross-sectional images of concha nasalis were demonstrated in humans, which could resolve cilial motion, cellular structures of the epithelium, vessels and blood cells. Mucus transport velocity was successfully determined. The endoscope may be used for diagnosis and treatment control of different lung diseases like cystic fibrosis or primary ciliary dyskinesia, which manifest already at the nasal mucosa.

An oxidation-resistant, recombinant Alpha-1 Antitrypsin produced in Nicotiana benthamiana.

Free Radic Biol Med. 2018 Mar 15;:

Abstract
Proteases and reactive oxygen species (ROS) have long been implicated in playing key roles in host tissue injury at sites of inflammatory processes dominated by macrophage activations and/or neutrophil infiltrations. Imbalances between proteases/antiproteases and ROS/antioxidants are recognized to contribute to amplification of inflammatory-based host tissue injury. This has been especially well-documented in such respiratory tract diseases as chronic obstructive pulmonary disease, cystic fibrosis, and acute respiratory distress syndrome. Inflammation-related protease/ROS disequilibria are further confounded by recognition that proteases can increase ROS by several different mechanisms and that ROS can inactivate proteases. The major human antiprotease, alpha-1 antitrypsin (AAT), is dramatically inactivated by ROS. AAT deficiency represents the most prevalent genetic predisposing factor leading to emphysema, a condition treated by replacement infusions of plasma-derived AAT (hAAT) at a cost of up to $200,000 per year. An updated method for production of a plant-made recombinant AAT (prAAT) engineered for enhanced oxidation resistance compared to hAAT is presented. prAAT shows comparable antintiprotease activity to hAAT, and retains full activity under oxidative conditions that would deactivate hAAT. Additionally, we show that prAAT has similar effectiveness in preventing neutrophil elastase-induced cell death in an in vitro human bronchial epithelial cell culture model. We conclude that prAAT potentially presents a viable method for the development of a "biobetter" AAT product that could be made available to subjects with a wide spectrum of inflammatory disorders characterized by overly aggressive neutrophilic infiltrations.

Abstract
The aim of this report is to assess whether the research issues priorities are perceived differently according to the Stakeholders (SH)'s individual knowledge of research topics and degree of training in biomedical research. Four groups of SH were enrolled in this study: 1. Skilled SH, specifically trained in biomedicine; 2. Unskilled untrained SH who responded to a written questionnaire in 2015; 3. SH who were trained for one year in a course delivered by professionals; 4. Untrained SH who responded to an online questionnaire in 2017. The large ranking order variability observed among groups addresses the question that the choices are markedly influenced by the SH's backgrounds. Such results emphasize the need to consider the education level and the delivery of ad hoc training activities by professionals to broaden the base of SH who may be considered qualified to transfer the Patient Centered Outcome Research principles into practice.

Anti-IgE therapy for allergic bronchopulmonary aspergillosis in people with cystic fibrosis.

Cochrane Database Syst Rev. 2018 Mar 18;3:CD010288

Authors: Jat KR, Walia DK, Khairwa A

Abstract
BACKGROUND: Cystic fibrosis is an autosomal recessive multisystem disorder with an approximate prevalence of 1 in 3500 live births. Allergic bronchopulmonary aspergillosis is a lung disease caused by aspergillus-induced hypersensitivity with a prevalence of 2% to 15% in people with cystic fibrosis. The mainstay of treatment includes corticosteroids and itraconazole. The treatment with corticosteroids for prolonged periods of time, or repeatedly for exacerbations of allergic bronchopulmonary aspergillosis, may lead to many adverse effects. The monoclonal anti-IgE antibody, omalizumab, has improved asthma control in severely allergic asthmatics. The drug is given as a subcutaneous injection every two to four weeks. Since allergic bronchopulmonary aspergillosis is also a condition resulting from hypersensitivity to specific allergens, as in asthma, it may be a candidate for therapy using anti-IgE antibodies. Therefore, anti-IgE therapy, using agents like omalizumab, may be a potential therapy for allergic bronchopulmonary aspergillosis in people with cystic fibrosis. This is an updated version of the review.
OBJECTIVES: To evaluate the efficacy and adverse effects of anti-IgE therapy for allergic bronchopulmonary aspergillosis in people with cystic fibrosis.
SEARCH METHODS: We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews. Last search: 29 September 2017.We searched two ongoing trial registries (Clinicaltrials.gov and the WHO trials platform). Date of latest search: 24 January 2018.
SELECTION CRITERIA: Randomized and quasi-randomized controlled trials comparing anti-IgE therapy to placebo or other therapies for allergic bronchopulmonary aspergillosis in people with cystic fibrosis.
DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed the risk of bias in the included study. They planned to perform data analysis using Review Manager.
MAIN RESULTS: Only one study enrolling 14 participants was eligible for inclusion in the review. The double-blind study compared a daily dose of 600 mg omalizumab or placebo along with twice daily itraconazole and oral corticosteroids, with a maximum daily dose of 400 mg. Treatment lasted six months but the study was terminated prematurely and complete data were not available. We contacted the study investigator and were told that the study was terminated due to the inability to recruit participants into the study despite all reasonable attempts. One or more serious side effects were encountered in six out of nine (66.67%) and one out of five (20%) participants in omalizumab group and placebo group respectively.
AUTHORS' CONCLUSIONS: There is lack of evidence for the efficacy and safety of anti-IgE (omalizumab) therapy in people with cystic fibrosis and allergic bronchopulmonary aspergillosis. There is a need for large prospective randomized controlled studies of anti-IgE therapy in people with cystic fibrosis and allergic bronchopulmonary aspergillosis with both clinical and laboratory outcome measures such as steroid requirement, allergic bronchopulmonary aspergillosis exacerbations and lung function.

Understanding of safety monitoring in clinical trials by individuals with CF or their parents: A qualitative analysis.

J Cyst Fibros. 2018 Mar 14;:

Authors: Kern-Goldberger AS, Hessels AJ, Saiman L, Quittell LM

Abstract
BACKGROUND: Recruiting both pediatric and adult participants for clinical trials in CF is currently of paramount importance as numerous new therapies are being developed. However, recruitment is challenging as parents of children with CF and adults with CF cite safety concerns as a principal barrier to enrollment. In conjunction with the CF Foundation (CFF) Data Safety Monitoring Board (DSMB), a pilot brochure was developed to inform patients and parents of the multiple levels of safety monitoring; the CFF simultaneously created an infographic representing the safety monitoring process. This study explores the attitudes and beliefs of CF patients and families regarding safety monitoring and clinical trial participation, and elicits feedback regarding the educational materials.
METHODS: Semi-structured interviews were conducted using a pre-tested interview guide and audio-recorded during routine CF clinic visits. Participants included 5 parents of children with CF <16years old; 5 adolescents and young adults with CF 16-21years old; and 5 adults with CF ≥22years old from pediatric and adult CF centers. The study team performed systematic text condensation analysis of the recorded interviews using an iterative process.
RESULTS: Four major thematic categories with subthemes emerged as supported by exemplar quotations: attitudes toward clinical trials, safety values, conceptualizing the safety monitoring process, and priorities for delivery of patient education. Participant feedback was used to revise the pilot brochure; text was shortened, unfamiliar words clarified (e.g., "pipeline"), abbreviations eliminated, and redundancy avoided.
CONCLUSIONS: Qualitative analysis of CF patient and family interviews provided insights into barriers to participation in clinical trials, safety concerns, perspectives on safety monitoring and educational priorities. We plan a multicenter study to determine if the revised brochure reduces knowledge, attitude and practice barriers regarding participation in CF clinical trials.

Nasal polyposis pathophysiology: Endotype and phenotype open issues.

Am J Otolaryngol. 2018 Mar 07;:

Authors: Brescia G, Zanotti C, Parrino D, Barion U, Marioni G

Abstract
PURPOSE: Endotyping chronic rhinosinusitis with nasal polyps (CRSwNP) poses a challenge for rhinologists nowadays. Phenotyping CRSwNP proved inappropriate as an approach to their classification because of their common clinical features. Endotyping, being based on the pathogenic mechanism, provides a precise picture more appropriate for use in clinical practice. Patients' treatment and follow-up can thus be tailored to cope with the degree of aggressiveness of a specific CRSwNP endotype. The aim of this study was to analyze the available information about the main currently accepted endotypes of CRSwNP; furthermore, we reported and commented evidence regarding some clinical conditions associated with nasal polyposis which could be related with new endotypes.
MATERIALS AND METHODS: Pubmed and Scopus electronic database were searched. The main available studies about CRSwNP endotyping published predominantly in the last 5 years were critically analyzed.
RESULTS: The pathophysiological features of some asthma-related CRSwNP (allergic fungal rhinosinusitis, aspirin-exacerbated respiratory disease) are quite well understood, including them among known endotypes of CRSwNP. On the other hand, because of their known pathophysiological mechanisms, some well-known diseases associated with aggressive forms of CRSwNP, such as eosinophilic granulomatosis with polyangiitis, primary ciliary dyskinesia and cystic fibrosis, should be investigated as potentially related with CRSwNP endotypes.
CONCLUSIONS: CRSwNP comprises several inflammatory endotypes defined by different pathogenic mechanisms. These endotypes correlate with the disease's clinical manifestations and behavior. A thorough understanding of CRSwNP endotypes will enable targeted medical therapies and tailored follow-up protocols.

Sites associated with Kalydeco binding on human Cystic Fibrosis Transmembrane Conductance Regulator revealed by Hydrogen/Deuterium Exchange.

Sci Rep. 2018 Mar 16;8(1):4664

Authors: Byrnes LJ, Xu Y, Qiu X, Hall JD, West GM

Abstract
Cystic Fibrosis (CF) is caused by mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR). Mutations associated with CF cause loss-of-function in CFTR leading to salt imbalance in epithelial tissues. Kalydeco (also called VX-770 or ivacaftor) was approved for CF treatment in 2012 but little is known regarding the compound's interactions with CFTR including the site of binding or mechanisms of action. In this study we use hydrogen/deuterium exchange (HDX) coupled with mass spectrometry to assess the conformational dynamics of a thermostabilized form of CFTR in apo and ligand-bound states. We observe HDX protection at a known binding site for AMPPNP and significant protection for several regions of CFTR in the presence of Kalydeco. The ligand-induced changes of CFTR in the presence of Kalydeco suggest a potential binding site.

A novel splicing variant in FLNC gene responsible for familial dilated cardiomyopathy in an extended Iranian family.

Abstract
Recent achievements in the genetic diagnosis of Dilated Cardiomyopathy (DCM) have disclosed rare variants in numerous genes encoding different types of myocardial proteins. However, the causative gene underlying the pathogenesis of about 60% of familial cases with DCM has not been identified. One novel gene introduced in 2016 for cardiac-restricted DCM is FLNC. In this study, we applied Whole Exome Sequencing (WES) and bioinformatics-based methods to a member of an extended non-consanguineous family with DCM history accompanied with fatal arrhythmia in at least four consecutive generations. We found a novel splice-site mutation in FLNC gene (c.2389 + 1G > A) which cosegregated with all symptomatic individuals in the family. Computational prediction software tools as well as RT-PCR method were used to evaluate the impact of the FLNC splice site mutation. This substitution leads to exon 15th donor-site disruption and exon skipping, which would result in a premature stop codon three aminocids downstream of the mutation site. The aberrantly mRNA transcript can induce nonsense-mediated mRNA decay. Although carrier individuals show remarkable variable expression regarding the severity of DCM as well as the disease age of onset, a highly penetrant fatal arrhythmia was found to be shared between them. We strongly suggest that the involvement of FLNC gene, due to haploinsufficiency, should be considered in familial cases with DCM, especially if accompanied with arrhythmia and increased incidence of sudden cardiac death.

Relationship between Deleterious Variation, Genomic Autozygosity, and Disease Risk: Insights from The 1000 Genomes Project.

Am J Hum Genet. 2018 Mar 10;:

Authors: Pemberton TJ, Szpiech ZA

Abstract
Genomic regions of autozygosity (ROAs) represent segments of individual genomes that are homozygous for haplotypes inherited identical-by-descent (IBD) from a common ancestor. ROAs are nonuniformly distributed across the genome, and increased ROA levels are a reported risk factor for numerous complex diseases. Previously, we hypothesized that long ROAs are enriched for deleterious homozygotes as a result of young haplotypes with recent deleterious mutations-relatively untouched by purifying selection-being paired IBD as a consequence of recent parental relatedness, a pattern supported by ROA and whole-exome sequence data on 27 individuals. Here, we significantly bolster support for our hypothesis and expand upon our original analyses using ROA and whole-genome sequence data on 2,436 individuals from The 1000 Genomes Project. Considering CADD deleteriousness scores, we reaffirm our previous observation that long ROAs are enriched for damaging homozygotes worldwide. We show that strongly damaging homozygotes experience greater enrichment than weaker damaging homozygotes, while overall enrichment varies appreciably among populations. Mendelian disease genes and those encoding FDA-approved drug targets have significantly increased rates of gain in damaging homozygotes with increasing ROA coverage relative to all other genes. In genes implicated in eight complex phenotypes for which ROA levels have been identified as a risk factor, rates of gain in damaging homozygotes vary across phenotypes and populations but frequently differ significantly from non-disease genes. These findings highlight the potential confounding effects of population background in the assessment of associations between ROA levels and complex disease risk, which might underlie reported inconsistencies in ROA-phenotype associations.

Abstract
N-glycanase deficiency (NGLY1 deficiency, NGLY1-CDDG), the first autosomal recessive congenital disorder of N-linked deglycosylation (CDDG), is caused by pathogenic variants in NGLY1. The majority of affected individuals have been identified using exome or genome sequencing. To date, no reliable, clinically available biomarkers have been identified. Urine oligosaccharide analysis was included as part of a routine evaluation for possible biomarkers in patients with confirmed NGLY1-CDDG. During the qualitative review of oligosaccharide profiles by an experienced laboratory director an abnormal analyte with a proposed structure of Neu5Ac1Hex1GlcNAc1-Asn was identified in NGLY1-CDDG patient urine samples. The same species has been observed in profiles from individuals affected with aspartylglucosaminuria, although the complete spectra are not identical. Additional studies using tandem mass spectrometry confirmed the analyte's structure. In addition to the known NGLY1-CDDG patients identified by this analysis, a single case was identified in a population referred for clinical testing who subsequently had a diagnosis of NGLY1-CDDG confirmed by molecular testing. Urine oligosaccharide screening by MALDI-TOF MS can identify individuals with NGLY1-CDDG. In addition, this potential biomarker might also be used to monitor the effectiveness of therapeutic options as they become available.

Abstract
Alport syndrome (AS) is a disorder of collagen IV, a component of glomerular basement membrane (GBM). The association of AS and immunocomplex nephropathies is uncommon. This is a case of a 37-year-old woman with family history of X-linked AS, including 4 affected sons. This patient developed full-blown nephrotic syndrome along a 3-month period, a presentation not consistent with AS progression. This scenario suggested an alternative diagnosis. A kidney biopsy was therefore performed, showing membranous nephropathy (MN) in addition to GBM structural alterations compatible with AS. Whole exome sequencing also confirmed the diagnosis of X-linked AS, revealing a heterozygous pathogenic mutation in COL4A5. While a negative serum anti-phospholipase A2 receptor did not rule out a primary form of MN, it was also uncertain whether positive serologic tests for syphilis could represent a secondary factor. It is currently unknown whether this unusual association represents AS susceptibility to immunocomplex-mediated diseases or simply an association of 2 disorders.
