Pathogenesis, Prophylaxis and Treatment of Uropathogenic Infections

Dear Colleagues,

For this Special Issue of Pathogens, we focus on uropathogens. Of particular concern is the rise in the incidence of urosepsis. A recent investigation of the prevalence of sepsis worldwide demonstrated a continuing decline in episodes of sepsis except for patients experiencing urosepsis [1]. Urosepsis is an overwhelming infection that originates in the urinary tract and spreads to the bloodstream, causing substantial morbidity and in some cases mortality. In adults, urosepsis accounts for 25% of all cases of sepsis [2]. 

In this issue, we hope to discuss new insights into the activity of uropathogens and the pathogenesis of urinary tract infections and urosepsis. We welcome a robust discussion of various uropathogens including less common pathogens and the role they may play in the rising numbers of urosepsis as well as the development of urinary tract infections. We look forward to considerations of the changing activity of pathogens in the urinary tract as compared to other areas of the body, new insights into the mechanisms of action of the more commonly recognized uropathogens and the potential role of the various microbiomes.

We recognize the role that the immune response plays in the pathophysiology of urosepsis is substantial and welcome articles on the involvement of cytokines in this process as well as the interplay of other aspects of the immune response.

Clinically, urosepsis occurs primarily due to obstruction or secondary to infected material in the urinary system. This Special Issue will address the clinical correlates of urosepsis, some of the clinical causes of urosepsis, and the identification and management of this disease. Recent work has suggested a connection between current clinical practice and the increasing incidence of urosepsis [3]. We intend for this phenomenon to be addressed.

This issue of Pathogens is expected to incorporate basic research as well as discussions of clinical management. We will end with a discussion of the treatment of urosepsis which must include considerations of early and late diagnosis, new definitions for the classification of sepsis, and an examination of goal-directed therapy and ongoing prevention practices.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pathogens is an international peer-reviewed open access monthly journal published by MDPI.
