Background: The purpose of this study was to evaluate the clinical benefits and safety of the long-term use of macrolides in patients with non-cystic fibrosis (non-CF) bronchiectasis.
Methods: Embase, Pubmed, the Cochrane Library and Web of Science databases were searched from inception up to March 2014. The primary outcome was the improvement of exacerbations of bronchiectasis. Secondary endpoints included changes of microbiology, lung function, quality of life, sputum volume, adverse events and macrolide resistance.
Results: The literature search yielded 139 studies, ten of which containing 601 patients were included in this meta-analysis. Macrolides showed a statistically-significant improvement in reducing acute exacerbations per patient during follow-up treatment (RR = 0.55, 95% CI: 0.47, 0.64, P < 0.001), increasing the number of patients free from exacerbations (OR = 2.81, 95% CI: 1.85, 4.26, P < 0.001), and prolonging time to a first exacerbation (HR = 0.38, 95% CI: 0.28, 0.53, P < 0.001). Macrolides maintenance treatment was superior to control with respect to attenuating FEV1 decline (p = 0.02), improving sputum volume (p = 0.009) and SGRQ total scores (p = 0.02), but showed a higher risk of adverse events, especially diarrhea (OR = 5.36; 95% CI: 2.06, 13.98, P = 0.0006). Eradication of pathogens was improved in the macrolide group (OR = 1.76, 95% CI: 0.91, 3.41, P = 0.09), while pathogen resistance caused by macrolides dramatically increased (OR = 16.83, 95% CI: 7.26, 38.99, P < 0.001). The new appearance of a microbiologic profile or participant withdrawal due to adverse events showed no significant differences between the two groups.
Conclusion: In patients with non-CF bronchiectasis, macrolide maintenance treatment can effectively reduce frequency of exacerbations, attenuate lung function decline, decrease sputum volume, improve quality of life, but may be accompanied with increased adverse events (especially diarrhea) and pathogen resistance.

Background And Aim: Pneumococcal conjugate vaccines (PCVs) have significantly reduced pediatric invasive pneumococcal disease (IPD). However, vaccine escape variants, the emergence of non-vaccine serotypes (NVTs), and antimicrobial resistance (AMR) remain ongoing concerns. We aimed to characterize long-term trends in serotype distribution, lineage composition, and AMR patterns among pediatric IPD cases following PCV introduction in two major Canadian urban centers: Calgary, Alberta, and Toronto, Ontario.

Background: Pediatric patients with autoimmune lymphoproliferative immunodeficiencies (ALPIDs) who exhibit autoimmune cytopenias are frequently diagnosed with immune thrombocytopenia (ITP), autoimmune hemolytic anemia (AIHA), or Evans syndrome (ES). These conditions generally necessitate long-term immunosuppressive therapy using medications that are often ineffective and highly toxic before the diagnosis of ALPIDs. A less harmful treatment strategy is needed.

Background: Inhaled corticosteroid (ICS) is frequently used for COPD. Based on the considerable adverse effects and the knowledge that many such patients do not gain benefit from this treatment, it remains unresolved whether ICS treatment can be managed with lower doses, or via an ICS-sparing strategy with periods with and without this medicine. The blood eosinophil count is a useful biomarker for steroid-responsive airway inflammation, and we want to investigate whether an individualized and eosinophil-guided approach on ICS treatment reduces ICS over-treatment and side effects.

Background: Graft-versus-host disease (GvHD) remains a major barrier to long-term survival after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Although calcineurin inhibitors (CNIs) are the cornerstone of GvHD prophylaxis, some patients cannot tolerate them, creating a critical need for alternative strategies.
Objective: To evaluate the efficacy and safety of sirolimus plus low-exposure CNIs as an alternative GvHD prophylaxis in CNI-intolerant recipients undergoing allo-HSCT.

Background: A paucity of evidence regarding use of endoscopic sinus surgery and antibiotics in managing chronic rhinosinusitis has contributed to a five-times variation in endoscopic sinus surgery rates, as well as variation in the use of antibiotics. The main aim of the present trial was to compare the clinical effectiveness of endoscopic sinus surgery or 3 months of clarithromycin treatment alongside intranasal medication in adults with chronic rhinosinusitis with or without nasal polyps.
Methods: In this pragmatic, three-arm, randomised, placebo-controlled phase 4 trial, participants were recruited from 20 secondary and tertiary care sites in the UK.
