Use of the BIOMIC Video System to evaluate the susceptibility of clinical yeast isolates to fluconazole and voriconazole by a disk diffusion method.

The ARTEMIS Global Antifungal Susceptibility Program provides the collection of epidemiological data and the results of the fluconazole and voriconazole susceptibility testing of yeast isolates. Participating in this study, a total of 7318 clinical yeast isolates were tested from different geographical areas in Hungary in the period 2001 to 2003. The species isolated most frequently was C. albicans (68.8%), followed by C. glabrata (11.8%), C. tropicalis (5.7%) and C. krusei (4.6%). Isolates of C. albicans, C. kefyr, C. lusitaniae, C. tropicalis and C. parapsilosis were highly susceptible to fluconazole (78.9-100%). The rates of isolation of fluconazole-resistant C. glabrata and C. krusei were higher in our study than the global mean in 2001 (28.2% and 87.5% vs. 18.3% and 70.2%, respectively). Differences were detected in the distribution of fluconazole-susceptibility data of C. glabrata isolates in the different counties of Hungary: most of the resistant isolates were observed in the eastern part of the country.

[Mucormycosis].

Over recent years the clinical importance of invasive fungal infections has significantly increased. Mucormycosis refers to a rare, life threatening, opportunistic disease caused by filamentous fungi of the order Mucorales. Most frequently mucormycosis occurs in patients with ketoacidotic diabetes and in neutropenic patients with acute leukaemia. This study of fifteen patients was conducted to evaluate the clinical characteristics of invasive mucormycosis, and goal was also to propose for an early diagnosis and management as survival can only be improved by aggressive surgery and antifungal therapy. In a retrospective analysis of the biopsy and autopsy records of the Department of Pathology at Szent László Hospital between 1992-2003 were evaluated fifteen histologically documented cases of mucormycosis. The underlying diseases were hematological malignancy with neutropenia in ten cases, chronic leukaemia with neutropenia, chronic leukaemia with latent diabetes mellitus and diabetes mellitus one case each. Three cases did not belong to any typical risk group. An in vivo diagnosis was made only in four patients with a rhinocerebral manifestation. Radical necrectomy and long-term antifungal therapy cured two of them. Two patients died of a generalised infection despite therapy. None of the systemic infections could be cured. The diagnosis was made post mortem in eleven patients. Selected clinical forms of mucormycosis are illustrated with short case reports.
