ABSTRACT
Intra-Abdominal Candidiasis (IAC) is frequent and associated with high mortality in intensive care unit (ICU) patients. Antifungal treatments may be overused due to a lack of diagnostic tools to rule out IAC. Serum 1,3-Beta-D-Glucan (BDG) concentrations are used to diagnose Candida infections, its concentration in peritoneal fluid (PF) may help to confirm or invalidate the diagnosis of IAC. We performed a non-interventional, prospective, multicenter study, at the Hospices Civils de Lyon, France, in seven ICU located in three different hospitals from December 2017 to June 2018. IAC was defined as the isolation of Candida in a sample collected from the intra-abdominal cavity under sterile conditions in patients displaying clinical evidence of intra-abdominal infection. Among the 113 included patients, 135 PF samples corresponding to 135 intra-abdominal infection episodes were collected and BDG concentrations were assessed. IAC accounted for 28 (20.7%) of the intra-abdominal infections. Antifungals were administered empirically to 70 (61.9%) patients; among them, 23 (32.9%) had an IAC. The median [IQR] BDG value was significantly higher in IAC (8100 [3000;15000] pg/mL) than in non-IAC samples (1961 [332;10650] pg/mL). BDG concentrations were higher in PF with Fecaloid aspect and in case of positive bacterial culture. For a BDG threshold of 125 pg/mL, the negative predictive value to assess IAC was 100%. In conclusion, low BDG PF concentrations could be used to rule out IAC. https://clinicaltrials.gov/ct2/show/NCT03469401.
Intra-Abdominal Candidiasis (IAC) is associated with a high mortality in Intensive Care Unit (ICU) patients. 1,3-Beta-D-Glucan (BDG), a component of Candida cell wall, was prospectively measured in peritoneal fluid from ICU patients Low peritoneal BDG concentrations may be used to rule out IAC.
ABSTRACT
BACKGROUND: Drug-induced immune hemolytic anemia (DIIHA) is a rare but sometimes severe side effect. CASE REPORT: We describe the case of a 32-year-old patient who presented a cardiovascular collapse and a severe hemolysis secondary to the injection of iomeprol, a contrast medium, after a carcinologic surgery. RESULTS: The evolution was favorable after blood transfusion and short catecholamine support. The biology showed drug-dependent antibodies after incubation with iomeprol. CONCLUSION: This case is the second report of DIIHA with iomeprol.
