IntroductionFever is frequently observed in critically ill patients. An independent association of fever with increased mortality has been observed in non-neurological critically ill patients with mixed febrile etiology. The association of fever and antipyretics with mortality, however, may be different between infective and non-infective illness.MethodsWe designed a prospective observational study to investigate the independent association of fever and the use of antipyretic treatments with mortality in critically ill patients with and without sepsis. We included 1,425 consecutive adult critically ill patients (without neurological injury) requiring > 48 hours intensive care admitted in 25 ICUs. We recorded four-hourly body temperature and all antipyretic treatments until ICU discharge or 28 days after ICU admission, whichever occurred first. For septic and non-septic patients, we separately assessed the association of maximum body temperature during ICU stay (MAXICU) and the use of antipyretic treatments with 28-day mortality.ResultsWe recorded body temperature 63,441 times. Antipyretic treatment was given 4,863 times to 737 patients (51.7%). We found that treatment with non-steroidal anti-inflammatory drugs (NSAIDs) or acetaminophen independently increased 28-day mortality for septic patients (adjusted odds ratio: NSAIDs: 2.61, P = 0.028, acetaminophen: 2.05, P = 0.01), but not for non-septic patients (adjusted odds ratio: NSAIDs: 0.22, P = 0.15, acetaminophen: 0.58, P = 0.63). Application of physical cooling did not associate with mortality in either group. Relative to the reference range (MAXICU 36.5°C to 37.4°C), MAXICU ≥ 39.5°C increased risk of 28-day mortality in septic patients (adjusted odds ratio 8.14, P = 0.01), but not in non-septic patients (adjusted odds ratio 0.47, P = 0.11).ConclusionsIn non-septic patients, high fever (≥ 39.5°C) independently associated with mortality, without association of administration of NSAIDs or acetaminophen with mortality. In contrast, in septic patients, administration of NSAIDs or acetaminophen independently associated with 28-day mortality, without association of fever with mortality. These findings suggest that fever and antipyretics may have different biological or clinical or both implications for patients with and without sepsis.Trial registrationClinicalTrials.gov: NCT00940654

In ischemic stroke, plasma cytokines and catecholamines were not predictors of neurological outcome at 1 month. In hemorrhagic stroke, high levels of IL-6 in the early phase indicated a poor neurological outcome.

A variety of fatal complications are associated with diabetes mellitus. Among these, diabetic ketoacidosis (DKA) figures largely in fatalities in young diabetics. Although hyperosmotic diuresis in DKA causes extreme fluid loss, acute renal failure is less common than expected in DKA. We treated a case of severe DKA with associated coma, acute respiratory failure, and acute renal failure in a 24-year-old man who had been diagnosed with type 1 diabetes mellitus at age 19. The comatose patient had been intubated before transfer to our hospital for intensive care. Despite infusion with isotonic saline and insulin, metabolic acidosis was refractory. On day 2, urine output decreased and pulmonary congestion developed, so we started continuous veno-venous hemodiafiltration (CVVHDF), which was effective against the metabolic acidosis; urine output increased gradually. CVVHDF was withdrawn on day 7, and the patient's renal function recovered completely. He was discharged from the intensive care unit (ICU) on day 14.
