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%).
Candida auris found among Russian ICU patients
Dr Barantsevich and colleagues describe a series of 49 trauma patients at an ICU in Moscow from whom Candida auris was isolated. Fluconazole resistance was widespread. However, no isolates were recovered by monthly swabbing of the hospital environment, healthcare workers’ hands and devices.
WHO adds Histoplasma antigen test to their Essential Diagnostics List
The World Health Organisation has updated its Essential Medicines List to the Histoplasma antigen test, which can be used on urine to diagnose histoplasmosis in 48 hours. Rolling out this test worldwide could save up to 48,000 lives in 5 years.
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
Blastomycosis mortality raised by ARDS and immunocompromisation
Blastomycosis is a rare fungal infection caused by inhaling spores of the fungus Blastomyces dermatitidis
Fungal asthma prevalence estimated for Sweden and Africa
Antifungal treatment can be useful for patients with severe asthma and fungal sensitisation, but this is limited by a lack of prevalence data. Two new papers aim to address this for Sweden (Backman et al) and 13 countries across Africa (Kwizera et al).
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
Side effects of long-term azole therapy
Azole antifungals are the first-line of treatment or prophylaxis for many fungal infections. They are often administered long-term (weeks to months), which can be associated with a number of adverse effects.
Paracoccidioidomycosis in South America should be a Neglected Fungal Tropical Disease
Paracoccidioidomycosis (PCM) should be listed as a Neglected Tropical Disease (NTD) according to GAFFI.
