IPF Care: a support program for patients with idiopathic pulmonary fibrosis treated with pirfenidone in Europe.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, and irreversible fibrotic lung disease that requires long-term treatment. Given the importance of adherence to treatment and management of adverse events (AEs), patients with IPF need long-term, high-quality support in living with their condition, and adhering to therapy so they can derive maximum benefit. The IPF Care Patient Support Program (IPF Care) provides support, education, and empowerment to patients receiving pirfenidone for the treatment of IPF in Europe, through the provision of frequent, patient-managed discussions with specialist IPF nurses. In this review, we describe the structure of IPF Care in the United Kingdom (UK) and Austria, two of the longest-running IPF Care programs to date, and describe the benefits that these programs provide to patients with IPF. Analysis of results demonstrates a low rate of discontinuation from the program, and provides insight into the questions and concerns that patients express, not only with respect to pirfenidone (the only approved treatment for IPF at the time of analysis), but also in relation to other aspects of living with IPF. Pirfenidone dose modifications are common in patients in IPF Care and AEs most commonly occur early in treatment, with the majority of affected patients continuing on a stable maintenance dose. This highlights the value of the advice and support that patients receive in IPF Care regarding management of AEs and staying on treatment. Patient satisfaction was high in a survey of the UK program, with patients reporting high scores regarding 'feeling in control of their condition', 'knowing what to expect from treatment', and 'feeling confident about how their disease is managed'. IPF Care in Europe will continue to evolve over time, striving to provide individually tailored support and patient-friendly information to improve treatment outcomes and quality of life for patients living with IPF.

Positive parental attitudes to participating in research involving newborn screened infants with CF.

BACKGROUND: Information regarding recruitment of infants to research studies following the diagnosis of cystic fibrosis (CF) via newborn screening (NBS) is not currently available. This study aimed to assess parental attitudes and the feasibility of recruiting and retaining both NBS infants with CF and healthy control infants to a longitudinal, observational study. METHODS: All infants underwent pulmonary function tests (PFTs) at ~3 and ~12months of age. Infants with CF had additional combined chest high resolution computed tomography (HRCT), bronchoscopy and broncho-alveolar lavage (BAL) at ~12months of age. Parental attitude questionnaires (PAQs) were administered to all parents following the ~3month PFTs and to parents of infants with CF after completion of all tests at ~12months. RESULTS: 86% (92/107) of families whose infant had CF consented to participate, of whom 92% had PFTs at ~3months of age with 99% of these having PFTs at ~12months of age. Recruitment of healthy controls was feasible but more challenging; 29% of those contacted agreed to participate; 73% of these had PFTs at ~3months of age; of whom 83% had repeated PFTs at ~12months of age. Completed PAQs were received from 71% of parents, (both of CF and healthy infants) at ~3months and from 58% parents of infants with CF at ~12months. Responses from the PAQs were generally positive, 95% of parents indicated they would recommend participation in such studies to other families. Discrepancies between responses at 3 and 12months suggested that parental understanding of what the research entailed developed during the course of the study. CONCLUSIONS: The high recruitment and retention rates for newly diagnosed CF NBS infants to this observational study are encouraging. These findings will help inform future study design both in the field of CF and other conditions diagnosed by NBS.

Lung function is abnormal in 3-month-old infants with cystic fibrosis diagnosed by newborn screening.

BACKGROUND: Long-term benefits of newborn screening (NBS) for cystic fibrosis (CF) have been established with respect to nutritional status, but effects on pulmonary health remain unclear. HYPOTHESIS: With early diagnosis and commencement of standardised treatment, lung function at ∼3 months of age is normal in NBS infants with CF. METHODS: Lung clearance index (LCI) and functional residual capacity (FRC) using multiple breath washout (MBW), plethysmographic (pleth) FRC and forced expirations from raised lung volumes were measured in 71 infants with CF (participants in the London CF Collaboration) and 54 contemporaneous healthy controls age ∼3 months. RESULTS: Compared with controls, and after adjustment for body size and age, LCI, FRC(MBW) and FRC(pleth) were significantly higher in infants with CF (mean difference (95% CI): 0.5 (0.1 to 0.9), p=0.02; 0.4 (0.1 to 0.7), p=0.02 and 0.9 (0.4 to 1.3), p<0.001, z-scores, respectively), while forced expiratory volume (FEV(0.5)) and flows (FEF(25-75)) were significantly lower (-0.9 (-1.3 to -0.6), p<0.001 and -0.7 (-1.1 to -0.2), p=0.004, z-scores, respectively). 21% (15/70) of infants with CF had an elevated LCI (>1.96 z-scores) and 25% (17/68) an abnormally low FEV(0.5) (below -1.96 z-scores). While only eight infants with CF had abnormalities of LCI and FEV(0.5), using both techniques identified abnormalities in 35% (24/68). Hyperinflation (FRC(pleth) >1.96 z-scores) was identified in 18% (10/56) of infants with CF and was significantly correlated with diminished FEF(25-75) (r=-0.43, p<0.001) but not with LCI or FEV(0.5). CONCLUSION: Despite early diagnosis of CF by NBS and protocol-driven treatment in specialist centres, abnormal lung function, with increased ventilation inhomogeneity and hyperinflation and diminished airway function, is evident in many infants with CF diagnosed through NBS by 3 months of age.
