Patients and families experience with pharmacist care at cystic fibrosis foundation accredited clinics.

Cystic fibrosis (CF) is a complex genetic, multiorgan disease. The CF Foundation (CFF) recommends a multidisciplinary team (physician, nurse, respiratory therapist, dietitian, physical therapist, social worker, mental health coordinator, clinic coordinator, and pharmacist) to work with patients and families. The objective of our study was to describe the impact of a pharmacist involved in the care of patients and families from their perspective. The CF Patient and Family Experience of Care (PFEC) is a voluntary, 50-question telephonic or internet-based survey designed to continuously collect information from patients and their families regarding their care experience. From August of 2017 through February of 2018, five questions were added to the internet survey to assess the impact of the pharmacist on the care experience. From the 666 respondents, 54% reported that a pharmacist was involved in their CF care. At two CF clinics designated as "full access" to a pharmacist, respondents reported a higher percentage of the CF-team discussed medications compared to those from three clinics designated as "limited access" to the pharmacist (95% vs 67%). Respondents in clinics with "full access" to a pharmacist were significantly more likely to get their medications refilled on time (78% vs 63%) and reported using fewer pharmacies to fill their medications. Pharmacist involvement in CF care may improve patient's access to medication and the ability to sustain use.

Impact of azithromycin treatment on macrophage gene expression in subjects with cystic fibrosis.

BACKGROUND: Azithromycin treatment improves clinical parameters in patients with CF, and alters macrophage activation from a pro-inflammatory (M1) phenotype to a pro-fibrotic, alternatively activated (M2) phenotype. The transcriptional profile of cells from patients receiving azithromycin is unknown. METHODS: Gene expression in association with macrophage polarization, inflammation, and tissue remodeling was assessed from sputum samples collected from patients with CF. Transcriptional profiles and clinical characteristics, including azithromycin therapy, were compared. RESULTS: Expression of NOS2 and TNFα was decreased in subjects receiving azithromycin, whereas expression of M2-associated genes was unaffected. Principal component analysis revealed gene expression profiles consistent with M1- (MMP9, NOS2, and TLR4) or M2-polarization (CCL18, fibronectin, and MR1) in select subject groups. These expression signatures did not significantly correlate with clinical characteristics. CONCLUSIONS: Pro-inflammatory gene expression was low in subjects receiving AZM. Genes were stratified into groupings characteristic of M1- or M2-polarization, suggesting that overall polarization status is distinct among patient groups.

Baseline characteristics and factors associated with nutritional and pulmonary status at enrollment in the cystic fibrosis EPIC observational cohort.

SUMMARY BACKGROUND: The EPIC Observational Study is an ongoing prospective cohort study investigating risk factors for and clinical outcomes associated with early Pseudomonas aeruginosa (Pa) acquisition in young children with cystic fibrosis (CF). OBJECTIVES AND HYPOTHESIS: To describe the baseline characteristics of the cohort and evaluate associations between potential risk factors and nutritional and respiratory characteristics at enrollment. We hypothesized that distinct demographic and environmental risk factors could be identified for poorer nutritional status and lung function at enrollment. METHODS: During 2004-2006, 1,700 children with CF were enrolled at 59 US CF centers. Children

Efficacy and Safety of a New Formulation of Pancrelipase (Ultrase MT20) in the Treatment of Malabsorption in Exocrine Pancreatic Insufficiency in Cystic Fibrosis.

Background. Pancreatic enzyme replacement therapy is the standard of care for treatment of malabsorption in patients with cystic fibrosis (CF) and exocrine pancreatic insufficiency (PI). Aim. To evaluate efficacy and safety of a new formulation of pancrelipase (Ultrase MT20) in patients with CF and PI. Coefficients of fat absorption (CFA%) and nitrogen absorption (CNA%) were the main efficacy parameters. Safety was evaluated by monitoring laboratory analyses, adverse events (AEs), and overall signs and symptoms. Methods. Patients (n = 31) were randomized in a crossover design comparing this pancrelipase with placebo during 2 inpatient evaluation periods (6-7 days each). Fat and protein/nitrogen ingestion and excretion were measured from food diaries and 72-hour stool collections. CFA% and CNA% were calculated for each period and compared. Results. Twenty-four patients provided analyzable data. This pancrelipase increased mean CFA% and CNA% (+34.7% and +25.7%, resp., P < .0001 for both), reduced stool frequency, and improved stool consistency compared with placebo. Placebo-treated patients reported more AEs, with gastrointestinal symptoms being the most frequently reported AE. Conclusions. This pancrelipase is a safe and effective treatment for malabsorption associated with exocrine PI in patients with CF.

Novel approach to the eradication of Pseudomonas aeruginosa in an infant with CF after outpatient treatment failure.

Intravenous continuous infusion of betalactam (CIBL) antibiotic and high dose extended interval (HDEI) aminoglycoside therapy theoretically maximize bacterial killing in treatment of Pseudomonas aeruginosa (PsA) in pulmonary exacerbations of cystic fibrosis (CF). We present the case of a 3-month-old female infant with CF who failed outpatient eradication of PsA with subsequent eradication using intravenous CIBL antibiotic and HDEI aminoglycoside therapy. This antibiotic combination should be considered in order to optimize pharmacodynamics for PsA eradication in CF patients before development of chronic colonization.

Physiologic evidence for high-frequency chest wall oscillation and positive expiratory pressure breathing in hospitalized subjects with cystic fibrosis.

BACKGROUND AND PURPOSE: This investigation identified ventilation distribution, gas mixing, lung function, and arterial blood oxyhemoglobin saturation (SpO2) physiologic responses to 2 independent airway clearance treatments, high-frequency chest wall oscillation (HFCWO) and low positive expiratory pressure (PEP) breathing, for subjects who had cystic fibrosis (CF) and who were hospitalized during acute and subacute phases of a pulmonary exacerbation. SUBJECTS: Fifteen subjects with moderate to severe CF were included in this study. METHODS: Subjects performed single-breath inert gas tests and spirometry before and immediately after HFCWO and PEP breathing at admission and discharge. Arterial blood oxyhemoglobin saturation was monitored throughout each treatment. RESULTS: At admission and discharge, PEP breathing increased SpO2 during treatment, whereas HFCWO decreased SpO2 during treatment. Ventilation distribution, gas mixing, and lung function improved after HFCWO or PEP breathing. DISCUSSION AND CONCLUSION: High-frequency chest wall oscillation and PEP breathing are similarly efficacious in improving ventilation distribution, gas mixing, and pulmonary function in hospitalized people with CF. Because SpO2 decreases during HFCWO, people who have moderate to severe CF and who use HFCWO should have SpO2 monitored during an acute exacerbation.
