The need for temperature modulation (mostly cooling) in critically ill patients is based on the expected benefits associated with decreased metabolic demands. However, evidence-based guidelines for temperature management in a majority of critically ill patients with fever are still lacking. The aim of our retrospective single-site observational study was to determine the differences in ICU treatment between patients in whom their temperature remained within the target temperature range for ≥25% of time (inTT group) and patients in whom their temperature was outside the target temperature range for <24% of time (outTT group). We enrolled 76 patients undergoing invasive mechanical ventilation for respiratory failure associated with sepsis. We observed no significant differences in survival, mechanical ventilation settings and duration, vasopressor support, renal replacement therapy and other parameters of treatment. Patients in the inTT group were significantly more frequently cooled with the esophageal cooling device, received a significantly lower cumulative dose of acetaminophen and significantly more frequently developed a presence of multidrug-resistant pathogens. In our study, achieving a better temperature control was not associated with any improvement in treatment parameters during ICU stay. A lower prevalence of multidrug-resistant pathogens in patients with higher body temperatures opens a question of a pro-pyrexia approach with an aim to achieve better patient outcomes.

Leptospirosis is an ubiquitous zoonosis with significant morbidity and mortality. Approximately 10 percent of human infections evolve into a severe form, with a sepsis-like disease, multiorgan failure, and significant mortality rate. The cornerstone of treatment of severe disease is antibiotic therapy, with the aims of preventing complications, reducing the duration of disease, and ultimately reducing mortality. The initiation of antibiotic chemotherapy can precipitate a febrile inflammatory reaction, also known as a Jarisch–Herxheimer reaction. We present a case report of a patient with severe leptospirosis, complicated by multiorgan failure with severe circulatory failure of distributive and cardiogenic etiology, possibly as a consequence of the Jarisch–Herxheimer reaction. The patient was treated with antimicrobial therapy and other supportive measures along with high-dose corticosteroid therapy, long-term mechanical ventilation, high-dose vasopressor therapy, and continuous veno-venous hemodiafiltration with extracorporeal cytokine removal.With this case, we would like to report on a patient presenting with two neglected diseases in our part of Europe, who was treated with novel therapeutic strategies.
