Background: Vitamin D deficiency is increasingly being recognized and treated in patients with cystic fibrosis, although the treatment guidelines are not proven and the effectiveness of vitamin D preparations is untested.
Objectives: The aims of this study were to determine the prevalence of 25-hydroxyvitamin D [25(OH)D] deficiency in a large cohort of adults with cystic fibrosis and to evaluate the effectiveness of supplementation with cholecalciferol.
Design: In this retrospective cohort design, baseline 25(OH)D concentrations were measured, and the effects of clinical interventions that involved either counseling on compliance or increasing supplemental cholecalciferol on serum 25(OH)D concentrations in those subjects with baseline concentrations
Results: Of 360 adults with cystic fibrosis, 249 (69%) had baseline 25(OH)D concentrations
Conclusions: A significant proportion of adults with cystic fibrosis have serum 25(OH)D concentrations

Doxycycline Versus Vancomycin for the Treatment of Methicillin-Resistant Acute Pulmonary Exacerbations in People With Cystic Fibrosis.

Background: Among people with cystic fibrosis (PwCF), methicillin-resistant (MRSA)-associated acute pulmonary exacerbations (APEs) have been increasing in prevalence and can cause rapid declines in lung function and increased mortality. Fortunately, since 2019, incidence has started to decline.
Objective: The purpose of this study was to evaluate if doxycycline has comparable efficacy to vancomycin for the treatment of APEs in PwCF.

Chronic infections represent a significant global health and economic challenge. Biofilms, which are bacterial communities encased in an extracellular polysaccharide matrix, contribute to approximately 80% of these infections. In particular, pathogens such as Pseudomonas aeruginosa and Staphylococcus aureus are frequently co-isolated from the sputum of patients with cystic fibrosis and are commonly found in chronic wound infections.

Background: Cystic fibrosis (CF) is caused by variants in a gene that encodes a protein essential for water and ion transport in the epithelial cells of exocrine organs. Given the possible relationship of this protein and conjunctival and corneal epithelium, the aim of this study was to evaluate ophthalmologic alterations in people with CF.
Methods: Forty-five people with CF underwent pulmonary evaluation including inflammatory score (IS).
Airway associated inflammation in post-transplant cystic fibrosis patients as a predictor of chronic lung allograft dysfunction (CLAD).

Aims: In cystic fibrosis lung transplant recipients (LTRs), graft dysfunction due to acute infections, rejection or chronic lung allograft dysfunction (CLAD) is difficult to distinguish. Characterisation of the airway inflammatory milieu could help detect and prevent graft dysfunction. We speculated that an eosinophil or neutrophil-rich milieu is associated with higher risk of CLAD.

The systemic use of corticosteroids for patients with severe community-acquired pneumonia (sCAP) remains controversial in clinical practice, particularly in terms of the safety profile of these drugs. This narrative review aims to analyse the available literature data concerning the safety of short-term steroid use in the treatment of sCAP, while also highlighting potential future research directions. Several trials and meta-analyses have evaluated corticosteroid therapy as an adjuvant treatment for sCAP, yielding heterogeneous results regarding its efficacy and safety.
