[Evaluation of zygomycosis cases by pooled analysis method reported from Turkey].
Zygomycosis is a rapidly-progressive invasive fungal disease with high mortality rates. Mucor, Rhizopus, Rhizomucor and Absidia species classified in Mucorales order, are the main causative agents of zygomycosis. Uncontrolled diabetes, hematologic malignancies, long term corticosteroid use and immunosuppressive therapies are the main predisposing factors for mucormycosis. In this study, we aimed to evaluate the mucormycosis cases from Turkey published in national and international databases in the last 17 years by means of age, gender, co-morbidities, signs and symptoms, diagnostic methods, therapeutic modalities, and mortality rate by pooling analysis. In our study, two national (http://uvt.ulakbim.gov.tr, http://www.turkmedline.net) and two international (www.ncbi.nlm.nih.gov, http://apps.webofknowledge.com) databases were used. A total of 64 manuscript (34 from national and 30 from international databases) published between 1995 and 2012, which were eligible for the study criteria and accessible as full text were included in the study. A total of 151 mucormycosis patients (71 female, 80 male; mean age: 45.4 ± 21.4 years) from these studies, with definitive diagnosis of invasive fungal infections according to the criteria of European Organization for Research and Treatment of Cancer (EORTC) have been evaluated. Of 151 patients 91 (60%) were diagnosed as rhinocerebral, 42 (%27.8) were sinoorbital, 7 (4.6%) were pulmonary, 6 (3.9%) were disseminated, 3 (1.9%) were skin, and 2 (1.3%) were gastrointestinal mycormycosis. The most common symptoms and signs were; swelling of eye and face (n= 95, 63%), fever (n= 72, 48%), nasal obstruction (n= 60, 40%), headache (n= 58, 38%) and opthtalmoplegia (n= 48, 32%). The most common co-morbidity was diabetes (49%) followed by hematological malignancies (39.7%). Mycological cultures were performed for 82 patients, and fungal growth were detected in the clinical specimens of 51 cases. The distribution of strains isolated in culture were as follows: Mucor spp. (n= 19, 37.2%), Rhizopus spp. (n= 13, 25.5%), Zygomycetes (n= 9, 17.6%), Rhizopus oryzae (n= 4, 7.8%), Rhizopus spp. + yeast (n= 3, 5.9%), Rhizomucor spp. (n= 2, 3.9%) and Rhizosporium spp. (n= 1, 1.9%). In 133 patients, histopathological investigation and in 126 patients radiological examinations were performed for diagnosis. Both surgical debridement and antifungal therapy were employed in 115 patients. Four patients had received only surgical debridement and 30 only antifungal therapies. Classical amphotericin B (AMP-B) therapy for 77 cases, liposomal AMP-B for 60 cases, liposomal AMP-B + posaconazole for six cases and lipid complex AMP-B for two cases have been started as antifungal therapies. Total mortality rate was detected as 54.3% (82/151). In conclusion, despite new diagnostic tools and therapeutic agents, mortality rates in mucormycosis are still very high. For the management, mucormycosis should be considered early in risky patients, and surgical debridement together with effective antifungal therapy should be applied as soon as possible.
