Aetiology of Significant Liver Test Abnormalities in a Single-Centre Cohort of People with Cystic Fibrosis Exposed to Elexacaftor/Tezacaftor/Ivacaftor, Utilizing the Updated RUCAM.

Background: The cystic fibrosis (CF) transmembrane conductance regulator (CFTR) modulator elexacaftor/tezacaftor/ivacaftor (E/T/I) has been associated with substantial multisystem benefits for people with CF eligible for therapy. In a minority, tolerance has been limited by hepatic toxicity. It is unknown whether there may be particular risk factors for significant drug-induced elevation in transaminases.

Effects of elexacaftor/tezacaftor/ivacaftor on liver fibrosis markers in adults with cystic fibrosis.

Background: There are limited studies to date on the effects of elexacaftor/tezacaftor/ivacaftor (E/T/I) on markers of liver fibrosis in adults with cystic fibrosis (CF). This study aims to analyse changes in makers of liver fibrosis before and after initiation of E/T/I in CF adults.

Methods: Outcome measures of liver fibrosis, including liver stiffness measurement (LSM) using FibroScan, AST-to-platelet-ratio index (APRI) and gamma-GT-to-platelet-ratio (GPR) were available in 74 CF adults following initiation of E/T/I.

Longitudinal effects of elexacaftor/tezacaftor/ivacaftor on liver tests at a large single adult cystic fibrosis centre.

Background: Elexacaftor/tezacaftor/ivacaftor (E/T/I) therapy has resulted in substantial improvements in health status for many with cystic fibrosis. Monitoring of liver tests is recommended due to observed rises in transaminases in trials and cases of hepatotoxicity. Comprehensive data in large populations of unselected individuals and those with established CF related liver disease (CFLD) is lacking.

Kidney and combined kidney and pancreas transplantation may be under-utilized in cystic fibrosis.

Cystic fibrosis (CF) is a multisystem disorder and represents the most common inherited condition leading to death in Western countries. Previous reports of chronic kidney disease (CKD) in CF focus on cases post lung, or other solid organ, transplantation but CKD in CF patients pre transplantation is increasingly recognized as a challenging complication of CF. CKD can evolve as a sequel to acute kidney injury for example after prolonged treatment with aminoglycoside antibiotics during episodes of infection.

Cardiac involvement in cystic fibrosis evaluated using cardiopulmonary magnetic resonance.

Cystic fibrosis (CF) transmembrane conductance regulator is expressed in myocardium, but cardiac involvement in CF remains poorly understood. The recent development of a combined cardiopulmonary magnetic resonance imaging technology allows for a simultaneous interrogation of cardiac and pulmonary structure and function. The aim of this study was to investigate myocardial manifestations in adults with CF, both in a stable state and during an acute respiratory exacerbation, and to investigate the relationship between cardiac and pulmonary disease.

Meteorological Factors Influence the Presence of Fungi in the Air; A 14-Month Surveillance Study at an Adult Cystic Fibrosis Center.

Background: Cystic fibrosis is an inherited disease that predisposes to progressive lung damage. Cystic fibrosis patients are particularly prone to developing pulmonary infections. Fungal species are commonly isolated in lower airway samples from patients with cystic fibrosis.

Non-invasive ventilation is associated with long-term improvements in lung function and gas exchange in cystic fibrosis adults with hypercapnic respiratory failure.

Background: Non-invasive ventilation (NIV) is an established treatment option for cystic fibrosis (CF) patients with type 2 respiratory failure but the benefits of this therapy remain unclear. This study examined the long-term outcomes and response to NIV in a large adult CF cohort.

Methods: All patients attending a UK adult CF Centre receiving NIV as treatment for hypercapnic respiratory failure over a nine-year period were studied prospectively.

Thoracic movement screening in adults with cystic fibrosis: reliability of the Manchester musculoskeletal screening tool.

Objectives: The Manchester Musculoskeletal Screening Tool (MMST) is used internationally to screen for pain, postural changes, and urinary incontinence in adults with cystic fibrosis (CF). The tool has been validated for the outcome measures of pain and incontinence but not for the thoracic movement section. The aim of this study was to assess intra (single rater) and inter-rater (between rater) reliability of the thoracic movement screen section of the MMST.

Influenza B outbreak at an adult cystic fibrosis centre - Clinical impact and factors influencing spread.

Introduction: An outbreak of Influenza B occurred at a large United Kingdom (UK) regional adult cystic fibrosis (CF) centre in May 2016. This was late in the UK 2015-2016 influenza season and occurred on a specialist ward with strict infection control procedures. This study investigates the spread of influenza, clinical consequences and potential contributing factors.

Lessons of the month 1: Salbutamol induced lactic acidosis: clinically recognised but often forgotten.

We present the case of an 83-year-old woman, with known asthma, admitted with increasing dyspnoea, wheeze and a productive cough. In addition to maintenance inhaled therapy, the patient was also on long-term mirtazapine and furosemide. Following acute treatment with nebulised salbutamol she became increasingly dyspnoeic and developed a metabolic acidosis with a significantly raised blood lactate level.

Investigation of a Pandoraea apista cluster common to adult and paediatric cystic fibrosis patients attending two hospitals in the same city.

Purpose: We examined evidence for transmission of Pandorea apista among cystic fibrosis (CF) patients attending paediatric and adult services in one city who had previously been found to harbour related isolates by pulsed-field gel electrophoresis (PFGE).

Methodology: The whole-genome sequences of 18 isolates from this cluster from 15 CF patients were examined, along with 2 cluster isolates from 2 other centres. The annotated sequence of one of these, Pa14367, was examined for virulence factors and antibiotic resistance-associated genes in comparison with data from a 'non-cluster' isolate, Pa16226.

Ralstonia infection in cystic fibrosis.

This study aimed to determine prevalence of Ralstonia spp. in cystic fibrosis patients, look for any evidence of cross infection and to describe clinical outcomes for patients infected by Ralstonia spp. Prevalence of Ralstonia spp.

Outcomes Following Bronchial Artery Embolisation for Haemoptysis in Cystic Fibrosis.

Background: Bronchial artery embolisation (BAE) is recommended for the treatment of massive haemoptysis in cystic fibrosis (CF), but there are no randomised controlled trials of this therapy and its role in sub-massive haemoptysis is unclear. This study aimed to determine the outcomes and safety of BAE in adults with CF.

Materials And Methods: All patients with CF undergoing BAE at our centre between March 2011 and January 2015 were identified at the time of the procedure.

Drug-related hepatitis in patients treated with standard anti-tuberculosis chemotherapy over a 30-year period.

Setting: Drug-induced hepatitis is known to occur in a proportion of patients on treatment for active tuberculosis (TB).

Design: We prospectively examined the incidence of drug-induced hepatitis in 2070 patients treated for TB with the standard regimen based on 6 months of rifampicin (R, RMP) and isoniazid (H, INH), with 2 months of initial pyrazinamide (Z, PZA) and ethambutol (E, EMB), over a 30-year period from 1981 to 2010, in Blackburn, UK.

Results: Of the 1031 (49.

Adequacy of diagnostic tests and surgical management of symptomatic invasive lobular carcinoma of the breast.

Introduction: Invasive lobular carcinoma (ILC) presents diagnostic and therapeutic challenges as it produces subtle radiological changes. It has been suggested that it is not suitable for breast conserving surgery (BCS). The aim of this study was to ascertain the diagnostic adequacy of modern mammography and ultrasonography in the context of a fast track symptomatic diagnostic clinic in the UK.

An international, multicentre evaluation and description of Burkholderia pseudomallei infection in cystic fibrosis.

Background: Several cases of Burkholderia pseudomallei infection in CF have been previously reported. We aimed to identify all cases globally, risk factors for acquisition, clinical consequences, and optimal treatment strategies.

Methods: We performed a literature search to identify all published cases of B.

Rapid Detection of Emerging Pathogens and Loss of Microbial Diversity Associated with Severe Lung Disease in Cystic Fibrosis.

Respiratory infection in cystic fibrosis (CF) is polymicrobial, but standard sputum microbiology does not account for the lung microbiome or detect changes in microbial diversity associated with disease. As a clinically applicable CF microbiome surveillance scheme, total sputum nucleic acids isolated by a standard high-throughput robotic method for accredited viral diagnosis were profiled for bacterial diversity using ribosomal intergenic spacer analysis (RISA) PCR. Conventional culture and RISA were performed on 200 paired sputum samples from 93 CF adults; pyrosequencing of the 16S rRNA gene was applied to 59 patients to systematically determine bacterial diversity.

Paget's disease of the male breast with underlying ductal carcinoma in situ ('DCIS').

Male breast cancer accounts for 1% of all breast malignancies and 0.1% of all male cancer death. Like Paget's disease, DCIS is a rare form of male breast malignancy.

What is the role of noninvasive ventilation in cystic fibrosis?

Purpose Of Review: The use of noninvasive ventilatory support in patients with cystic fibrosis (CF) has increased exponentially over the past 2 decades. This review examines the current knowledge and considers potential future directions for use of noninvasive ventilation in CF patients.

Recent Findings: Noninvasive ventilation was originally reported as a bridge to transplantation in CF patients with severe respiratory failure but is now used as a long-term treatment modality for patients with respiratory failure independent of transplant status.

The effect of the weather on pulmonary exacerbations and viral infections among adults with cystic fibrosis.

The effect of changes in the weather on the respiratory health of patients with cystic fibrosis (CF) is unclear. We conducted a prospective study to determine the impact of climate and season on the incidence of viral respiratory infections (VRI) and pulmonary exacerbations (PEx) among adults with CF. Between December 2010 and April 2012, 98 adults with CF were followed for 12 months.
