Candida antigen titre dilution and death after injury.

Background: Candida infections affect outcome after injury. Candida antigen titres were used to detect these infections early. This study was undertaken to correlate Candida antigen titre dilution with conventional injury scoring and outcome after severe injury.
Methods: Candida antigen titres were determined by agglutination when clinically apparent source(s) of Candida were noted, when Candida was grown in culture of body fluids, or when unexplained clinical deterioration occurred. The findings were compared with the Injury Severity Score (ISS).
Results: Seventy-five seriously injured adults (median ISS 25 (range 18-50)) developed raised Candida antigen titres. Multivariate analysis showed that age and Candida antigen titre correlated significantly with mortality, but not with each other. Culture evidence of Candida, or lack thereof, did not correlate with Candida antigen titre or mortality. Sixteen of 75 patients died, 14 from bacterial sepsis and none from Candida infection.
Conclusion: In seriously injured adults, the mortality rate is related to raised Candida antigen titres. The association between Candida antigen titre and mortality, although real, remains unexplained.
