Cystic fibrosis (CF) lung disease begins during infancy, and acute respiratory infections increase the risk of early disease development and progression. Microbes involved in advanced stages of CF are well characterized, but less is known about early respiratory colonizers.

P. aeruginosa is a leading cause of nosocomial infection and infection in patients with cystic fibrosis. While P. aeruginosa infection and treatment can be complicated by a variety of antimicrobial resistance and virulence mechanisms, pathogen virulence is rarely recorded in a clinical setting.

Abstract Background Treatment of cystic fibrosis (CF) exacerbations can be challenging secondary to antimicrobial resistance due to chronic airway infection, multiple treatment courses, and frequent use of suppressive antibiotics. For these reasons, many antimicrobial stewardship (AMS) principles may not be practical for the CF population. The objective of this study was to determine perceptions of AMS among CF healthcare providers internationally. Methods Six questions regarding AMS were incorporated into an email survey focusing on antimicrobial resistance in CF. Healthcare providers (HCP) were identified through list-servs and CF-related organizations internationally. Results Three-hundred and seventy-eight HCP from 30 countries responded to the survey (see Figure 1). Within their institutions, more than half had access to a CF-specific pharmacist, infectious disease consultation, and/or written CF exacerbation guidelines. An AMS program was only available for 39% of respondents. Most HCP stated that choosing and dosing antibiotics correctly and minimizing resistance were the main goals of AMS. Stewardship activities they felt would be helpful during CF exacerbations included the following: choice of antibiotics (83%), duration of antibiotics (78%), antibiotic dosing (68%), therapeutic drug monitoring (63%), reducing drug interactions (53%), and avoiding toxicity (50%). Nine percent of HCP stated that they did not think AMS was advantageous during exacerbations. Conclusion Although most CF HCP have access to individual aspects of AMS, fewer had access to a formal AMS program. Help with antibiotics during exacerbations was identified as an important aspect for input from AMS programs. Disclosures All authors: No reported disclosures.

Abstract Background Children with cystic fibrosis (CF) can develop life-threatening infections of Mycobacterium abscessus. These present a significant clinical challenge, particularly when the strains involved are resistant to antibiotics. Recent evidence of within-patient subclones of M. abscessus in adults with CF suggests the possibility that within-patient diversity may be relevant for the treatment of pediatric CF patients. Methods We performed whole-genome sequencing (WGS) on 32 isolates of M. abscessus that were taken from multiple body sites of 2 patients with CF who were undergoing treatment at Great Ormond Street Hospital, United Kingdom, in 2015. Results We found evidence of extensive diversity within patients over time. A clustering analysis of single nucleotide variants revealed that each patient harbored multiple subpopulations, which were differentially abundant between sputum, lung samples, chest wounds, and pleural fluid. The sputum isolates did not reflect the overall within-patient diversity and did not allow for the detection of subclones with mutations previously associated with macrolide resistance (rrl 2058/2059). Some variants were present at intermediate frequencies before the lung transplants. The time of the transplants coincided with extensive variation, suggesting that this event is particularly disruptive for the microbial community, but the transplants did not clear the M. abscessus infections and both patients died as a result of these infections. Conclusions Isolates of M. abscessus from sputum do not always reflect the entire diversity present within the patient, which can include subclones with differing antimicrobial resistance profiles. An awareness of this phenotypic variability, with the sampling of multiple body sites in conjunction with WGS, may be necessary to ensure the best treatment for this vulnerable patient group.

Antimicrobial resistance and the adaptation of microbial life to antibiotics are recognised as a major healthcare challenge. Whereas most social science engagement with antimicrobial resistance has focussed on aspects of ‘behaviour’ (prescribing, antibiotic usage, patient ‘compliance’, etc.), this article instead explores antimicrobial resistance in the context of building design and healthcare architecture, focussing on the layout, design and ritual practices of three cystic fibrosis outpatient clinics. Cystic fibrosis is a life-threatening multi-system genetic condition, often characterised by frequent respiratory infections and antibiotic treatment. Preventing antimicrobial resistance and cross-infection in cystic fibrosis increasingly depends on the spatiotemporal isolation of both people and pathogens. Our research aims to bring to the fore the role of the built environment exploring how containment and segregation are varyingly performed in interaction with material design, focussing on three core themes. These include, first, aspects of flow, movement and the spatiotemporal choreography of cystic fibrosis care. Second, the management of waiting and the materiality of the waiting room is a recurrent concern in our fieldwork. Finally, we take up the question of air, the intangibility of airborne risks and their material mitigation in the cystic fibrosis clinic.
