Suspect histoplasmosis in returning travellers from an endemic area presenting with fever and cough

Histoplasmosis can present in a variety of ways, making it difficult to diagnose. Dr Staffolani and colleagues carried out a systematic review of 835 cases of histoplasmosis (including 45 clusters) from the literature, among immunocompetent patients who had recently returned from an endemic area. Manifestations included fever (91%), cough (55%), constitutional symptoms (58%), headache (52%) and chest pain (41%).

Cryptococcosis in HIV- patients show atypical presentation, leading to delayed diagnosis

Cryptococcosis is well known as a complication of HIV/AIDS, but it can also affect those who are immunosuppressed for other reasons. Dr Marr and colleagues describe a set of 138 patients from the US. Around half (49%) had CNS involvement but only just over a quarter (27.8%) had a fever.

LDBio rapid Aspergillus IgG test sensitive and specific for CPA

Lateral flow rapid diagnostics are sorely needed for many fungal infections. Scientists at the University of Manchester evaluated LDBio’s Aspergillus IgG test on patients at the National Aspergillosis Centre (UK). Compared to existing diagnostics, this test was more sensitive (91.6%) and more specific (98.0%) for chronic pulmonary aspergillosis

Cluster of paracoccidioidomycosis cases in children in Argentina during the 1982-3 El Niño anomaly

Serious systemic paracoccidioidomycosis infections are often associated with men working in agriculture. Dr Guisano and colleagues describe a cluster of six cases in children in the NEA area of Argentina that occurred during the 1982-3 El Niño Southern Oscillation climatic anomaly, and suggest that climatic and anthropogenic changes may have played a role
