    Abstract Background: Mycetoma, a chronic infection of the skin and underlying structures, affects those with a close relationship to the land, often in resource-poor areas of the world. Whether caused by any one of a variety of fungus or bacteria, mycetoma causes significant disability and mortality. Acknowledged as a neglected tropical disease (NTD) by the World Health Organization (WHO) in 2016, mycetoma is susceptible to being misunderstood, misdiagnosed, and mismanaged. In an effort to shift the balance in favor of recognition and effective treatment, sound epidemiological understanding is required.
    Methods and findings: In this paper, a literature review of case reports and series (332 papers in total) is presented as three maps. We identified 19,494 cases dating from 1876 to 2019, with cases contracted in 102 countries. The first map shows where mycetoma has ever been reported, the second shows how many cases have been reported, and the third shows the ratio of eumycetoma (fungal) to actinomycetoma (bacterial). Most cases are found in Mexico, India, and Sudan, where mycetoma is studied rigorously. We identified emergence of new geographical loci, including the United States, Venezuela, Italy, China, and Australia. Notably, mycetoma is reported far outside the tropics. In the Americas, bacterial forms dominate, whereas, in Africa and Asia, the picture is more varied.
    Conclusions: With better understanding of the epidemiology of mycetoma, more can be done to direct education, preventive measures, and treatment to at-risk areas, enabling a reduction in disease burden.

    Abstract Background: The burden of serious fungal infections in Honduras is unknown. The diagnosis of fungal diseases relies on almost exclusively on microscopy and culture limiting an accurate estimate of the burden of disease.
    Objectives: The primary objective of the study was to estimate the burden of serious fungal infections in Honduras using previously described methods.
    Methods: National and international demographic data on population, HIV, tuberculosis, asthma, COPD and cancer were obtained. A thorough literature search was done for all epidemiological studies and case series of serious fungal diseases. Using these risk populations and whatever incidence and prevalence could be found that was most pertinent to Honduras, a burden estimate was derived.
    Results: The estimated number of serious fungal infection was estimated to be between 178,772 and 179,624 with nearly 2300 cases of these representing opportunistic infections in people living with HIV. The incidence of histoplasmosis and cryptococcosis in people living with HIV is high and estimated to be 4.3 and 4.6 cases per 100,000 population respectively. Approximately 12,247-13,099 cases of aspergillosis and 164,227 of other serious fungal infections were estimated to occur each year.
    Conclusion: An accurate estimate of the burden of serious fungal infections in Honduras is unknown but based on our results, likely significant. Serious fungal infections represent an important public health problem in Honduras affecting approximately 1.8% of the population. There is a clear need for better access to diagnostic tools and antifungals to conduct research to better understand the impact of fungal diseases in Honduras.

    Abstract Background: Invasive aspergillosis (IA) among haematological malignancy patients is rarely diagnosed or studied in many African countries. Aspergillus galactomannan (GM) enzyme immunoassay (EIA) utilized in aiding diagnosis is not readily accessible in Ghana. Previous studies have evaluated the IMMY sōna Aspergillus GM lateral flow assay (LFA) and suggested it as a potential alternative to the GM EIA.
    Objectives: We aimed to use the LFA in international (EORTC/ MSGERC) definitions to obtain preliminary data on IA among patients with haematological malignancies in Ghana with a focus on the prevalence and antifungal prophylaxis.
    Methods: We conducted a pilot study among patients with haematological malignancies at the Korle-Bu Teaching Hospital, Ghana using the LFA, culture and computed tomography scan to screen for and classify IA cases according to international definitions.
    Results: A total of 56 adult patients were recruited including acute leukaemia 14 (25.0%), chronic leukaemia 38 (67.9%), and lymphoma 4 (7.1%). Nine (16.1%) patients had a history of severe neutropenic episodes. All patients were on at least one chemotherapy drug. Three (5.4%) patients met the criteria for IA, comprising two probable IA in acute myeloid leukaemia and one possible IA in non-Hodgkin's lymphoma and constitutes one of five (20%) patients with ongoing severe neutropenia. The LFA was diagnostic in two IA patients. The IA cases were among 49 (87.5%) patients who did not receive antifungal prophylaxis.
    Conclusion: Proactive diagnostic approaches to IA and effective antifungal prophylaxis may be significant in the management of haematological malignancy patients with severe neutropenia in Ghana.

    Abstract The burden of serious fungal infection in Thailand is increasing but data regarding its incidence and prevalence are lacking. In this study we aimed to estimate the burden of serious fungal diseases in Thailand based on the size of the populations at risk and available epidemiological databases. Data derived from The Bureau of Epidemiology, Department of Disease Control, Thai Ministry of Public Health, World Health Organisation, international and local reports, and some unreported data were used. When no data existed, risk populations were used to estimate frequencies of fungal infections, using previously described methodology by LIFE. Recurrent vulvovaginal candidiasis (>4 episodes per year) is estimated to occur in 3,310 per 100,000 population. Using a previously described rate that 14/10,000 admissions are with fungaemia and 94% of those are Candida, we estimated 8,650 patients with candidaemia. The prevalence of chronic pulmonary aspergillosis is relatively high with a total of 19,044, approximately half subsequent to pulmonary tuberculosis. Invasive aspergillosis is estimated to affect 941 patients following leukaemia therapy, transplantations, and chronic obstructive pulmonary disease, approximately 1.4/100,000. In addition, allergic bronchopulmonary aspergillosis and severe asthma with fungal sensitisation were estimated at approximately 58.4/100,000 and 77/100,000, respectively. Given approximately 8,134 new cases of AIDS annually, cryptococcal meningitis, Pneumocystis pneumonia, and Talaromyces marneffei infection are estimated at 1.9/100,000, 2.6/100,000, and 0.3/100,000, respectively. The present study indicates that about 1.93% (1,254,562) of the population is affected by serious fungal infections. Owing to the lack of data, reports, and statistics, the number of patients with mycoses in Thailand can only be estimated.

    Abstract We aimed to estimate the burden of serious fungal infections in Egypt, currently unknown, based on the size of the populations at risk and available epidemiological data. Data were obtained from the World Health Organization (WHO), the Joint United Nations Programme on HIV/AIDS (UNAIDS), and published reports with clearcut denominators. When no data existed, risk populations were used to estimate frequencies of fungal infections, using previously described methodology. The population of Egypt in 2011 was ∼82,500,000; 31% children, and 8% women >60 years of age. Amongst about 21.8 million women aged 15-50 years, recurrent vulvovaginal candidiasis (≥4 episodes/year) is estimated to occur in 1.3 million (3,169/100,000 females). Using a low international average rate of 5/100,000, we estimate 4,127 cases of candidaemia, and 619 patients with intra-abdominal candidiasis. Amongst the survivors of pulmonary tuberculosis (TB) in Egypt in 2012, 319 new cases of chronic pulmonary aspergillosis (CPA) are likely, a prevalence of 1,005 post-TB and a total prevalence estimate of 3,015 CPA patients in all. Asthma is common in Egypt, affecting 9.4% of adults, 5.35 million, and so ABPA and SAFS were estimated in around 162/100,000 and 214/100,000 respectively. Invasive aspergillosis is estimated to affect 495 patients following leukaemia therapy, there are an estimated 37 cases in renal and liver transplant recipients, and an estimated 132 patients develop IA in the context of lung cancer. Amongst 641,000 COPD admissions to hospital each year, 8,337 patients develop IA. The total HIV-infected population is small, with an estimated 6,500 patients, 2,500 not on antiretroviral therapy. Amongst HIV-infected patients, 38 (0.6%) cases of cryptococcal meningitis and 125 (1.9%) cases of Pneumocystis pneumonia are estimated each year. Fungal keratitis is common, with 28-55% (mean 40%) of corneal infections being fungal, an estimated total of 11,550 cases. The present study indicates that 2% of the Egyptian population is affected by fungal infections. The estimates are certainly incomplete, and need further epidemiological and diagnostic studies.

    Abstract Background: Early recognition and diagnosis of allergic bronchopulmonary aspergillosis (ABPA) is critical to improve patient symptoms, and antifungal therapy may prevent or delay progression of bronchiectasis and development of chronic pulmonary aspergillosis.
    Objective: A recently commercialized lateral flow assay (Aspergillus ICT) (LDBio Diagnostics, Lyons, France) detects Aspergillus-specific antibodies in <30 minutes, requiring minimal laboratory equipment. We evaluated this assay for diagnosis of ABPA compared to diseased (asthma and/or bronchiectasis) controls.
    Methods: ABPA and control sera collected at the National Aspergillosis Centre (Manchester, UK) and/or from the Manchester Allergy, Respiratory and Thoracic Surgery research biobank were evaluated using the Aspergillus ICT assay. Results were read both visually and digitally (using a lateral flow reader). Serological Aspergillus-specific IgG and IgE, and total IgE titres were measured by ImmunoCAP.
    Results: For 106 cases of ABPA versus all diseased controls, sensitivity and specificity for the Aspergillus ICT were 90.6% and 87.2%, respectively. Sensitivity for 'proven' ABPA alone (n = 96) was 89.8%, and 94.4% for 'presumed' ABPA (n = 18). 'Asthma only' controls (no bronchiectasis) and 'bronchiectasis controls' exhibited 91.4% and 81.7% specificity, respectively. Comparison of Aspergillus ICT result with Aspergillus-specific IgG and IgE titres showed no evident immunoglobulin isotype bias. Digital measurements displayed no correlation between ImmunoCAP Aspergillus-specific IgE level and ICT test line intensity.
    Conclusions: The Aspergillus ICT assay exhibits good sensitivity for ABPA serological screening. It is easy to perform and interpret, using minimal equipment and resources; and provides a valuable simple screening resource to rapidly distinguish more serious respiratory conditions from Aspergillus sensitization alone.
