Specimen Test Considerations Remarks/Recommendations Serum Mannan and AntiMannan • Combined detection RECOMMENDED Serial determinations may be necessary. High NPV Other antibodies (such as Serion ELISA classic) • Limited data for candidemia ß-D-Glucan • Not specific for Candida Septifast • Limited data for candidemia No recommendation In house PCR • No third party validation data available No recommendation No recommendation RECOMMENDED (for Fungitell) No recommendation for other tests. Serial determinations are recommended (twice a week). High NPV. Not validated in children Beta D Glucan 3 different tests (2 Japan, 1 USA) Variable quality of data: retrospective vs. prospective; heterogenous Different cut offs used “pangungal” – except cryptococcus and mucorales Sensitivity 45-70%; specificity and NPV high High false-positives: up to 30% in ICU- bacteraemia, antibiotics, pre-/analytical contaminations Influence of ongoing antifungal prophylaxis/therapy not known Costs, complex analytical procedures: automated assay in the pipeline Performance of (1-3) – β – D - Glucan No studies (patients) Sensitivity % (95% Cl) Specificity % (95% Cl) Karageorgopoulos, CID 2011 Proven & probable IFI 16(2979) 77% (67-84) 85% (80-90) Onishi, JCM 2012 A, IC, PJP IA, IC 31 PJP 12 80% (77-82) 96% (92-98) 82 % (81-83) 84% (83-86) 15 76% (67-83) 0.85 (73-92) Karageorgopoulos, CMI 2012 14 (2800) 95& (91-97) 86% (92-90) Lamoth, CID 2012 For 2 consecutive tests 6 (1771) 50% (64-65) 99% (97-99.5) Lu, Intern Med 2011 False positive BG results Haemodialysis using cellulose membranes Albumin Intravenous immune globulin Use of cellulose depht filters for intavenous administration • Gauze packing of serosal surfaces (abdominal surgery) • Intravenous amoxicillin-clavulanic acid (AZITROMICIN and PENTAMIDINE inhibit the BG assay) • • • • Markers of sepsis and organ dysfunction at time of blood culture Bacterial sepsis Candida sepsis P value n CRP PCT 190 [115-316] 12.9 [2.6-81.2] 94 [66-129] 0.71 [0.5-1.1] 0.002 0.001 SOFA WBC T (°C) 8 [7-13] 14.3 [10.6-16.4] 38.0 [37.0-38.4] 5[3-8] 11.6 [8.4-15.7] 37.8 [37.0-38.3] 0.010 0.336 0.493 PROCALCITONINA Journal of Infection 2010; 60:425-430 Dou Y – H et al Diagn Micr Inf Dis 2013 Risk predictive models for INVASIVE CANDIDIASIS in critically ill patients Colonization index Nº sites/Nº sites screened 2 x weekly >0.5 or ≥ 0.4 corrected Candida score Surgery on ICU admission TPN Severe sepsis Candida colonization > 3 points Ostrosky, 2009 4th day of I ICU stay Major (two): Sepsis + CVC + MV + one of TPN (day 1-3) Dialysis (day 1-3) Major surgery (within 7 days) Pancreatitis (within 7 days) Immusup/steroids (within 7 days) Shorr, 2009 Dupont, 2003 Michalopoulos, 2003 Age > 65 y Tº < 36.7º Severe mental status Cachexia Previous hospit. 30 days Healthcare facility MV Female gender Upper GI origin peritonitis Cardiovasc. failure BAS 48 h before onset of peritonitis MV > 10 days Nosocomial bacterial infection Cardiop. bypass time > 120 m.
