Septic AKI in ICU patients. diagnosis, pathophysiology, and treatment type, dosing, and timing: a comprehensive review of recent and future developments

Evidence is accumulating showing that septic acute kidney injury (AKI) is different from non-septic AKI. Specifically, a large body of research points to apoptotic processes underlying septic AKI. Unravelling the complex and intertwined apoptotic and immuno-inflammatory pathways at the cellular level will undoubtedly create new and exciting perspectives for the future development (e.g., caspase inhibition) or refinement (specific vasopressor use) of therapeutic strategies. Shock complicating sepsis may cause more AKI but also will render treatment of this condition in an hemodynamically unstable patient more difficult. Expert opinion, along with the aggregated results of two recent large randomized trials, favors continuous renal replacement therapy (CRRT) as preferential treatment for septic AKI (hemodynamically unstable). It is suggested that this approach might decrease the need for subsequent chronic dialysis. Large-scale introduction of citrate as an anticoagulant most likely will change CRRT management in intensive care units (ICU), because it not only significantly increases filter lifespan but also better preserves filter porosity. A possible role of citrate in reducing mortality and morbidity, mainly in surgical ICU patients, remains to be proven. Also, citrate administration in the predilution mode appears to be safe and exempt of relevant side effects, yet still requires rigorous monitoring. Current consensus exists about using a CRRT dose of 25 ml/kg/h in non-septic AKI. However, because patients should not be undertreated, this implies that doses as high as 30 to 35 ml/kg/h must be prescribed to account for eventual treatment interruptions. Awaiting results from large, ongoing trials, 35 ml/kg/h should remain the standard dose in septic AKI, particularly when shock is present. To date, exact timing of CRRT is not well defined. A widely accepted composite definition of timing is needed before an appropriate study challenging this major issue can be launched

Study of Leishmania pathogenesis in mice : experimental considerations

Although leishmaniases are endemic in 98 countries, they are still considered neglected tropical diseases. Leishmaniases are characterized by the emergence of new virulent and asymptomatic strains of Leishmania spp. and, as a consequence, by a very diverse clinical spectrum. To fight more efficiently these parasites, the mechanisms of host defense and of parasite virulence need to be thoroughly investigated. To this aim, animal models are widely used. However, the results obtained with these models are influenced by several experimental parameters, such as the mouse genetic background, parasite genotype, inoculation route/infection site, parasite dose and phlebotome saliva. In this review, we propose an update on their influence in the two main clinical forms of the disease: cutaneous and visceral leishmaniases

Research in progress: report on the ICAIL 2017 doctoral consortium

This paper arose out of the 2017 international conference on AI and law doctoral consortium. There were five students who presented their Ph.D. work, and each of them has contributed a section to this paper. The paper offers a view of what topics are currently engaging students, and shows the diversity of their interests and influences

Critical care nephrology: could it be a model of multidisciplinarity in ICU nowadays for other sub-specialities – the jury is out

Patrick M Honoré,1 Rita Jacobs,1 Olivier Joannes-Boyau,2 Elisabeth De Waele,1 Jouke De Regt,1 Viola Van Gorp,1 Herbert D Spapen1 1ICU Department, Universitair Ziekenhuis Brussel, Vrije Universiteit Brussel, Brussels, Belgium; 2ICU Department, Haut Leveque University Hospital of Bordeaux, University of Bordeaux 2, Pessac, France Abstract: Emergency and critical care medicine have grown into robust self-supporting disciplines with an increasing demand for dedicated highly-skilled physicians. In the past, “core” specialists were asked to offer bedside advice in acute care wards. In the same regard, critical care medicine and nephrology have been fighting but finally emerged altogether with the concept of critical care nephrology almost 20 years ago. Indeed, polyvalence is no longer a valid option in modern critical care. Uniting forces between disciplines represents the only way to cope with the increasing complexity and cumulating knowledge in the critical care setting. For this reason, the wide array of upcoming acute care sub-specialities must be committed to unrestricted growth and development. This will require competent manpower, a well-designed technical framework, and sufficient financial support. The worldwide success of critical care nephrology proves the feasibility for this concept.
