Objective: Previous research exploring patient-practitioner communication in relation to adherence in cystic fibrosis (CF) is limited. This UK study explored the views of adults with CF on how treatment adherence (related to all CF treatments) is discussed in routine CF care.

Methods: 12 White British adults (ten females; aged 20-37 years; mean 30.

Article Synopsis
  • - Daily inhaled therapy is crucial for maintaining lung health in people with cystic fibrosis (PwCF), but measuring adherence to therapy can be complicated due to varying treatment regimens among patients.
  • - This study utilizes historical data from the UK CF Registry (2011-2015) to create a prediction rule for identifying current Psuedomonas aeruginosa (PA) status in PwCF, achieving high accuracy rates in predictions.
  • - By effectively identifying patients with chronic PA infection using past registry data, the researchers aim to improve adherence monitoring and quality assessments of care across different medical centers.

Article Synopsis
  • A study checked how much inhaled medicine people with cystic fibrosis (CF) received compared to how much they actually used.
  • It found that many people had more medicine than they needed, leading to a waste of money—about £1,124 per person on average.
  • The results show that people who didn't use their medicine as much wasted the most, suggesting that it's important to help people use their medicines properly.

Objectives: To undertake a process evaluation of an adherence support intervention for people with cystic fibrosis (PWCF), to assess its feasibility and acceptability.

Setting: Two UK cystic fibrosis (CF) units.

Participants: Fourteen adult PWCF; three professionals delivering adherence support ('interventionists'); five multi-disciplinary CF team members.

Background: Preventative medication reduces hospitalisations in people with cystic fibrosis (PWCF) but adherence is poor. We assessed the feasibility of a randomised controlled trial of a complex intervention, which combines display of real time adherence data and behaviour change techniques.

Methods: Design: Pilot, open-label, parallel-group RCT with concurrent semi-structured interviews.

Among adults with cystic fibrosis (CF), medication adherence is low and reasons for low adherence are poorly understood. Our previous exploratory study showed that stronger 'habit' (ie, automatically experiencing an urge to use a nebuliser) was associated with higher nebuliser adherence. We performed a secondary analysis of pilot trial data (n=61) to replicate the earlier study and determine whether habit-adherence association exists in other cohorts of adults with CF.

Pseudomonas aeruginosa status influences cystic fibrosis (CF) clinical management but no 'gold standard' definition exists. The Leeds criteria are commonly used but may lack sensitivity for chronic P. aeruginosa.

Background: Pulmonary P. aeruginosa infection is associated with poor outcomes in cystic fibrosis (CF) and early diagnosis is challenging, particularly in those who are unable to expectorate sputum. Specific P.

Rationale: Pulmonary infection and malnutrition in cystic fibrosis are associated with decreased survival. Glutamine has a possible anti-microbial effect, with a specific impact against Pseudomonas aeruginosa. We aimed to test the hypothesis that oral glutamine supplementation (21 g/day) for 8 weeks in adults with cystic fibrosis would decrease pulmonary inflammation and improve clinical status.

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.

Pseudomonas aeruginosa produces quorum sensing signal molecules that are potential biomarkers for infection.A prospective study of 60 cystic fibrosis patients with chronic P. aeruginosa, who required intravenous antibiotics for pulmonary exacerbations, was undertaken.

Background: Chronic loss of appetite in cystic fibrosis concerns both individuals and families. Appetite stimulants have been used to help cystic fibrosis patients with chronic anorexia attain optimal body mass index and nutritional status. However, these may have adverse effects on clinical status.

An individual's response to anti-asthma medication is likely to arise from a complex interaction between social, environmental and inherited factors. Studies indicate that genetic factors may account for 60-80% of the heterogeneity in treatment responsiveness in asthmatics. Identifying the genetic variants responsible may potentially lead to the development of novel treatments, improved effectiveness in the use of existing treatments and better prediction of efficacy in phase II and III trials.

The possibility that immune responses to autoantigens may contribute to the development of atopic disease has been largely ignored. In this paper, we describe the chromosomal localization of the gene for squamous cell carcinoma-associated reactive antigen for cytotoxic T cells (SART-1). The SART-1 gene localized to a region of 11q12-13 showing strong linkage to atopy in previous studies.
