These data provide evidence that azithromycin affects the inflammatory process at the level of the macrophage and shifts macrophage polarization towards the alternatively activated phenotype. This recently defined M2 phenotype has been described in conditions in which pulmonary inflammation and fibrosis are major determinants of clinical outcome, but the concept of antibiotics altering macrophage phenotype has not yet been critically evaluated.

Routine use of azithromycin therapy for the prevention of BPD cannot be recommended. The early treatment of Ureaplasma colonized/infected patients might be beneficial, but a larger multi-centered trial is required to assess this more definitively.

Our findings suggest an increase in both MR and arginase expression as pulmonary function declines in PA-infected patients with CF. These markers of an alternatively activated macrophage phenotype give cause for future study to define the function of macrophage activation states in the CF lung.

Background: Azithromycin reduces the severity of illness in patients with inflammatory lung disease such as cystic fibrosis and diffuse panbronchiolitis. Bronchopulmonary dysplasia (BPD) is a pulmonary disorder which causes significant morbidity and mortality in premature infants. BPD is pathologically characterized by inflammation, fibrosis and impaired alveolar development. The purpose of this study was to obtain pilot data on the effectiveness and safety of prophylactic azithromycin in reducing the incidence and severity of BPD in an extremely low birth weight (≤ 1000 grams) population.

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.

WHAT'S KNOWN ON THIS SUBJECT: Although it has been shown that cystic fibrosis newborn screening is beneficial, the strategies vary widely, and there has been uncertainty about the costs and consequences of different algorithms and whether screening methods/decisions should be based on assumed cost differences. WHAT THIS STUDY ADDS:This study contributes by offering a comparison of both costs, assessed comprehensively, and the consequences associated with the 2 most popular screening methodologies, immunoreactive trypsinogen/immunoreactive trypsinogen and immunoreactive trypsinogen/DNA, by using a decision-tree framework allowing variation in the model parameters.abstract OBJECTIVES: Because cystic fibrosis can be difficult to diagnose and treat early, newborn screening programs have rapidly developed nationwide but methods vary widely. We therefore investigated the costs and consequences or specific outcomes of the 2 most commonly used methods. METHODS:With available data on screening and follow-up, we used a simulation approach with decision trees to compare immunoreactive trypsinogen (IRT) screening followed by a second IRT test against an IRT/DNA analysis. By using a Monte Carlo simulation program, variation in the model parameters for counts at various nodes of the decision trees, as well as for costs, are included and applied to fictional cohorts of 100 000 newborns. The outcome measures included the numbers of newborns given a diagnosis of cystic fibrosis and costs of screening strategy at each branch and cost per newborn. RESULTS:Simulations revealed a substantial number of potential missed diagnoses for the IRT/IRT system versus IRT/DNA. Although the IRT/IRT strategy with commonly used cutoff values offers an average overall cost savings of $2.30 per newborn, a breakdown of costs by societal segments demonstrated higher out-of-pocket costs for families. Two potential system failures causing delayed diagnoses were identified relating to the screening protocols and the follow-up system. CONCLUSIONS:The IRT/IRT screening algorithm reduces the costs to laboratories and insurance companies but has more system failures. IRT/DNA offers other advantages, including fewer delayed diagnoses and lower out-of-pocket costs to families. Pediatrics 2012;129:e339-e347 AUTHORS:
