Abstract
BACKGROUND: The burden of fungal disease in the UK is unknown. Only limited data are systematically collected. We have estimated the annual burden of invasive and serious fungal disease.
METHODS: We used several estimation approaches. We searched and assessed published estimates of incidence, prevalence or burden of specific conditions in various high-risk groups. Studies with adequate internal and external validity allowed extrapolation to estimate current UK burden. For conditions without adequate published estimates, we sought expert advice.
RESULTS: The UK population in 2011 was 63,182,000 with 18% aged under 15 and 16% over 65. The following annual burden estimates were calculated: invasive candidiasis 5,142; Candida peritonitis complicating chronic ambulatory peritoneal dialysis 88; Pneumocystis pneumonia 207 to 587 cases, invasive aspergillosis (IA), excluding critical care patients 2,901 to 2,912, and IA in critical care patients 387 to 1,345 patients, , <100 cryptococcal meningitis cases. We estimated 178,000 (50,000-250,000) allergic bronchopulmonary aspergillosis cases in people with asthma, and 873 adults and 278 children with cystic fibrosis. Chronic pulmonary aspergillosis is estimated to affect 3,600 patients, based on burden estimates post tuberculosis and in sarcoidosis.
CONCLUSIONS: Uncertainty is intrinsic to most burden estimates due to diagnostic limitations, lack of national surveillance systems, few published studies and methodological limitations. The largest uncertainty surrounds IA in critical care patients. Further research is needed to produce a more robust estimate of total burden.
