In order to correlate the findings of two serological tests, double immunodiffusion (IDD) and immunoblotting (IB), with the clinical diagnosis and follow-up of paracoccidioidomycosis (PCM), 325 serum samples from PCM patients were tested at the beginning of specific therapy and after its completion. Group I included 245 PCM patients at the onset of symptoms without treatment. In 221 cases (90.2%) the IDD showed positive reactions and in 24 (9.8%) the results were negative. Of the 24 IDD negative samples, 23 were investigated by IB and were positive. Group II included 80 PCM patients under follow-up after treatment. There were four cases of relapse in which the IDD and IB tests were positive (100%). Among the 76 cases with inactive mycotic infection, the IDD was negative in 71.2% and positive in 28.8%; the IB was positive in all cases (100%). The control group (Group III) included 27 samples from patients with other mycoses, tuberculosis and from healthy individuals. All showed negative IDD tests but positive reactions with IB, which could be abolished by serum dilutions without altering the PCM reactivity. Therefore, the utilization of the IB, an immunoenzymatic method for the diagnosis of PCM, raised the sensitivity to 100%.

In order to contribute to the knowledge of the relative frequency of chronic fungal diseases and assess the performance of diagnostic laboratories in Argentina, a multicenter study was performed with the participation of 25 medical centers located in 12 different provinces and Buenos Aires City. Between 04-01-2000 and 03-30-2001, 965 serum specimens from patients clinically suspected of having histoplasmosis (HP), paracoccidioidomycosis (PCM), coccidioidomycosis (CM) or aspergilosis were analyzed. Agar immunodiffusion tests (IDD) were done locally. All positive and 35% of negative sera were retested in the reference center. Results of laboratories of origin showed 98.8% concordance with those of reference center. Antibodies against any of the etiological agents were detected in 120 specimens from 98 patients. Endemic mycoses (HP, PCM and CM) were diagnosed in 70 patients (71.4%) and aspergilosis in 28 (28.6%). The frequencies of the different mycoses in decreasing order were PCM 47 patients (47.9%), aspergilosis 28 patients (28.6%), HP 13 patients (13.3%) and CM 10 patients (10.2%). The study was carried out on a voluntary basis and some areas of the country were not represented. However, the frequencies were in range with the expected rates in the population under study.

We developed and analyzed an Enzyme-Linked Immunosorbent Assay (ELISA) in order to detect antibodies in sera from sporotrichosis patients. We used a crude antigen of Sporothrix schenckii sensu stricto, obtained from the mycelial phase of the fungi. Positive sera were analyzed by other serological techniques such as double immunodiffusion (IGG) and counterimmunoelectrophoresis (CIE). The assay was validated by using sera from patients with other pathologies such as: histoplasmosis, paracoccidioidomycosis, tuberculosis, leishmaniasis, lupus and healthy individuals as negative controls. For the Sporothrix schenckii sensu stricto antigen, we found a 100% of specificity by every technique and sensitivity higher than 98% with IDD, CIE and ELISA. Our results show a high sensitivity and specificity for the Sporothrix schenckii sensu stricto antigen, so it can be used for IDD, CIE and ELISA. The results suggest that this antigen could be used in conjunction with other conventional tests for differential diagnosis and may be useful for monitoring the disease progression and response to treatment.
