Efficacy and safety of oral ciprofloxacin were studied in a prospective study at three cystic fibrosis centres, covering 24 in-patients suffering from cystic fibrosis and acute bronchopulmonary exacerbation. The patients were between 10 and 17 years of age. Pseudomonas infection was present in 75% of these patients. Despite frequent persistence of the pathogens, clinical improvement was noted in 75% of the treated children. A definite increase of the average MIC was not seen in 20 cases of persisting strains. No serious side effects occurred during the 14-day oral treatment course. Ciprofloxacin is a useful alternative to conventional parenteral treatment with antibiotics in patients suffering from cystic fibrosis and infections of the airways.

Impact of SARS-CoV-2 spike antibody positivity on infection and hospitalisation rates in immunosuppressed populations during the omicron period: the MELODY study.

Background: In the UK, booster COVID-19 vaccinations have been recommended biannually to people considered immune vulnerable. We investigated, at a population level, whether the absence of detectable anti-SARS-CoV-2 spike protein IgG antibody (anti-S Ab) following three or more vaccinations in immunosuppressed individuals was associated with greater risks of infection and severity of infection.
Methods: In this prospective cohort study using UK national disease registers, we recruited participants with solid organ transplants (SOTs), rare autoimmune rheumatic diseases (RAIRDs), and lymphoid malignancies.

Carboxyl-terminus of Hsp70-Interacting Protein (CHIP) is an E3 ubiquitin ligase that marks misfolded substrates for degradation. Hyper-activation of CHIP has been implicated in multiple diseases, including cystic fibrosis and cancer, suggesting that it may be a potential drug target. However, there are few tools available for exploring this possibility.

Cystic fibrosis (CF) is characterized by abnormal mucus hydration due to a defective CF Transmembrane Regulator (CFTR) protein, leading to the production of difficult-to-clear mucus. This causes airflow obstruction, recurrent infections, and respiratory complications. Chronic lung infections are the leading cause of death for CF patients and inhaled tobramycin is the first-in-line antibiotic treatment against these infections, mainly caused by Pseudomonas aeruginosa in adult patients.

This paper presents a comprehensive review of the current literature, clinical trials, and products approved for the delivery of antibiotics to the lungs. While there are many literature reports describing potential delivery systems, few of these have translated into marketed products. Key challenges remaining are the high doses required and, for powder formulations, the ability of the inhaler and powder combination to deliver the dose to the correct portion of the respiratory tract for maximum effect.

The cystic fibrosis transmembrane conductance regulator (CFTR) is an anion channel that is dysfunctional in individuals with cystic fibrosis (CF). The permeability of CFTR can be experimentally manipulated though different mechanisms, including activation via inducing the phosphorylation of residues in the regulatory domain as well as altering the gating/open probability of the channel. Phosphorylation/activation of the channel is achieved by exposure to compounds that increase intracellular cAMP, with forskolin and IBMX commonly used for this purpose.
