Preparing for an era of untreatable gonorrhea.

ABSTRACT: The proportion of Neisseria gonorrhoeae isolates with reduced susceptibility to extended-spectrum cephalosporins (ESCs) has increased rapidly since 2006. Clinicians, researchers, and public health officials need to be prepared for the possibility of an era of untreatable gonorrhea. This review focuses on the evidence for current gonorrhea treatment recommendations, potential future treatment options, and other methods to control gonorrhea.In addition to an increase in isolates with decreased susceptibility to ESCs, there have been reported treatment failures to both cefixime and ceftriaxone. In response, some countries have increased the recommended cephalosporin dose, and most now recommend dual therapy with an ESC and azithromycin. The pharynx has been implicated as a site for acquiring resistance through transformation with commensal Neisseria species or induced resistance through subtherapeutic antimicrobial levels. Thus, appropriate screening of the pharynx and treatment with a regimen that eradicates gonorrhea from the pharynx is necessary. At present, several studies are evaluating various novel treatment regimens in preparation for an era of untreatable gonorrhea.Screening for asymptomatic infections, maintaining culture capacity to monitor antimicrobial resistance, treating with ceftriaxone and azithromycin, and ensuring that all sexual partners are treated are among the best strategies to control gonorrhea in the current clime.

Project description:BACKGROUND:Congenital myasthenic syndromes (CMS) are a heterogeneous group of inherited neuromuscular disorders sharing the common feature of fatigable weakness due to defective neuromuscular transmission. Despite rapidly increasing knowledge about the genetic origins, specific features and potential treatments for the known CMS entities, the lack of standardized classification at the most granular level has hindered the implementation of computer-based systems for knowledge capture and reuse. Where individual clinical or genetic entities do not exist in disease coding systems, they are often invisible in clinical records and inadequately annotated in information systems, and features that apply to one disease but not another cannot be adequately differentiated. RESULTS:We created a detailed classification of all CMS disease entities suitable for use in clinical and genetic databases and decision support systems. To avoid conflict with existing coding systems as well as with expert-defined group-level classifications, we developed a collaboration with the Orphanet nomenclature for rare diseases, creating a clinically understandable name for each entity and placing it within a logical hierarchy that paves the way towards computer-aided clinical systems and improved knowledge bases for CMS that can adequately differentiate between types and ascribe relevant expert knowledge to each. CONCLUSIONS:We suggest that data science approaches can be used effectively in the clinical domain in a way that does not disrupt preexisting expert classification and that enhances the utility of existing coding systems. Our classification provides a comprehensive view of the individual CMS entities in a manner that supports differential diagnosis and understanding of the range and heterogeneity of the disease but that also enables robust computational coding and hierarchy for machine-readability. It can be extended as required in the light of future scientific advances, but already provides the starting point for the creation of FAIR (Findable, Accessible, Interoperable and Reusable) knowledge bases of data on the congenital myasthenic syndromes.
