Identification of the cause and subsequent specific therapy are indicated for those prolonged or relapsing fevers that follow abdominal surgery. On rare occasions, these fevers can be attributed to potentially life-threatening occult infections, including maxillary sinusitis, acute cholecystitis, antibiotic-related pseudomembranous colitis, toxic shock syndrome, systemic candidiasis, and transfusion-related cytomegalovirus disease, malaria, and babesiosis. Early recognition and appropriate treatment of these infections relieve anxiety, reduce hospital costs, and increase patient survival rates.

Epitope mapping with sera from a range of infected patients showed that antibodies are commonly produced which cross-react with a number of epitopes on human heat shock protein 90 (HSP 90). Such autoreactive antibodies were particularly frequent in patients suffering from systemic candidiasis (9 patients), invasive aspergillosis (6 patients), ABPA (2 patients), a patient with aspergilloma and one with malaria. The patient with malaria recognized similar epitopes to those with invasive aspergillosis and candidiasis including the highly conserved epitope LKVIRKVIRK and an epitope NNLGTI which was otherwise only recognised by patients with candidiasis. Crossreacting antibodies to relatively few epitopes occurred in patients with Enterococcus faecalis and Corynebacterium jeikeium endocarditis. This was contrasted with the results from 6 patients with systemic lupus erythematosus (SLE) who were positive on immunoblot against fungal HSP 90. These did not react with the above epitopes but reacted with other areas within human HSP 90.

An immunogenic aminopeptidase of Candida albicans was purified by high-performance liquid chromatography. It was then used for the development of an enzyme-linked immunosorbent assay to detect antibodies directed against this antigen in sera from patients with candidiasis. This enzyme specifically cleaves the L-Arg-7-amino-4-methyl-coumarin substrate at pH 7.4 and was detected in the crude extract of different C. albicans isolates. Sera used for this study were obtained from healthy blood donors or from patients with one of the following: systemic candidiasis, aspergillosis, cryptococcosis, toxoplasmosis, or malaria. The statistical analysis demonstrates significant differences between absorbency values obtained with sera from patients with candidiasis and with sera from the other groups (P = 0.000001). Diagnostic parameters show high diagnostic specificity of 97% and a sensitivity of 83% at a cutoff value of 0.425 and suggest the usefulness of this aminopeptidase for the diagnosis of systemic candidiasis.
