Mucormycosis in Africa: Epidemiology, diagnosis and treatment outcomes.

Mucorales fungi cause mucormycosis, an invasive and rapidly progressive disease which increasingly affects mostly immunocompromised but also immunocompetent individuals. The objective of this study was to highlight the epidemiology, diagnostic modalities, treatment and overall survival of mucormycosis in Africa. We searched for relevant publications in PubMed, Google Scholar and African Journal Online databases covering the period 1960-2022. A total of 147 articles were identified, of which 66 were included in the review, detailing 408 individual cases from 12 African countries; 330 (80.9%) from North Africa, 63 (15.4%) from Southern Africa, seven (1.7%) from East Africa, seven (1.7%) from West Africa and a single case (0.2%) from Central Africa. The most frequently described clinical forms were rhino-orbital-cerebral (n = 307, 75.2%) and gastrointestinal (n = 51, 12.5%). Diabetes mellitus, COVID-19, malignancies and neutropaenia were the commonest underlying risks in 203 (49.8%), 101 (24.8%), 65 (15.9%) and 53 (13.0%) cases respectively. Most cases, 296 (72.5%) were diagnosed by histopathology. Fungal aetiology was identified in 38 (9.3%), of which the commonest was Rhizopus oryzae/arrhizus (27/38, 71.1%). Of the 408 cases, 334 (81.9%) patients received antifungal therapy, while 244 (59.8%) had surgery. In cases with a specified outcome, survival rate was 59.1% (228/386). Based on case reporting, a substantial burden of mucormycosis occurs in North Africa but the disease is rarely reported in most of the sub-Saharan region. Establishing a comprehensive registry for standardised data collection could improve understanding of the epidemiology of mucormycosis in the region.

Defining and managing COVID-19-associated pulmonary aspergillosis: the 2020 ECMM/ISHAM consensus criteria for research and clinical guidance.

Severe acute respiratory syndrome coronavirus 2 causes direct damage to the airway epithelium, enabling aspergillus invasion. Reports of COVID-19-associated pulmonary aspergillosis have raised concerns about it worsening the disease course of COVID-19 and increasing mortality. Additionally, the first cases of COVID-19-associated pulmonary aspergillosis caused by azole-resistant aspergillus have been reported. This article constitutes a consensus statement on defining and managing COVID-19-associated pulmonary aspergillosis, prepared by experts and endorsed by medical mycology societies. COVID-19-associated pulmonary aspergillosis is proposed to be defined as possible, probable, or proven on the basis of sample validity and thus diagnostic certainty. Recommended first-line therapy is either voriconazole or isavuconazole. If azole resistance is a concern, then liposomal amphotericin B is the drug of choice. Our aim is to provide definitions for clinical research and up-to-date recommendations for clinical management of the diagnosis and treatment of COVID-19-associated pulmonary aspergillosis.
