Epidemiology, Clinical, Radiological and Biological Characteristics, and Outcomes of Mucormycosis: A Retrospective Study at a French University Hospital

Year: 2024

Type: article

Abstract: Purpose: Mucormycosis is a rare but emerging and life-threatening infection caused by environmental mold, with a mortality rate of 30–70% despite progress in management. A better understanding could improve its management. Method: We conducted a single-center retrospective study of all cases of mucormycosis observed over a decade at the University Hospital of Caen. Results: Between 2014 and 2024, 18 cases of mucormycosis were identified, predominantly in males (n = 11, 65%). Most patients had hematological malignancies (n = 16, 89%). Seven cases were proven, and eleven were classified as probable. The main locations of infection were pulmonary (n = 12, 67%). Since 2021, we have observed an increase in the number of cases, rising from three between 2014 and 2021 to fifteen between 2021 and 2024. Among the 12 patients with pulmonary mucormycosis, all presented with fever except 1, and 67% required oxygen therapy. Chest computed tomography scans revealed an inverse halo sign in one-third of the patients. The first-line treatment consisted of amphotericin B in seventeen patients, posaconazole in one patient, and isavuconazole in one patient. Surgery was performed on seven patients. In cases of cutaneous mucormycosis, all patients underwent surgery, and none died within three months after the diagnosis. Overall, the three-month mortality rate was 39%. Surgical management was associated with a reduction in mortality (0% vs. 64%, p = 0.013). Conclusions: This study highlights the role of PCR for early diagnosis and the key role of surgery in improving clinical outcomes while underscoring the need for better-adapted therapeutic protocols for these rare infections.
