AB Antibodies against a 33-kDa antigen from Coccidioides immitis were
detected by ELISA in patients' cerebrospinal fluid (CSF). Anti-33-kDa
antibodies were detected at dilutions > 1:80 in only 1 (1.4%) of 73
patients without coccidioidal meningitis but in 74 (71.8%) of 103 with
meningitis. Anti-33-kDa antibodies were detected in 53 (91.4%) of 58
patients whose anti-coccidioidal complement-fixing (CF) antibodies were
detectable and in 21 (46.7%) of 45 patients whose CSF was negative by CF
test (positive predictive value, 99%; negative predictive value, 71%;
sensitivity, 72%; specificity, 99%). Anti-33-kDa antibodies, among which
IgG1 was the dominant subclass, increased when infections worsened and
decreased when patients' conditions improved. Antibody concentration
appeared to be independent of most baseline findings, although only 1 of
5 patients coinfected with human immunodeficiency virus had initially
detectable antibodies. Measurement of anti-33-kDa antibodies is a
sensitive indicator of coccidioidal meningitis and of its clinical
course.
