Type 2 diabetes: a risk factor for acquisition of and increased mortality from cryptococcal disease
November 02 2017
Type 2 diabetes has recently emerged as a putative risk factor for cryptococcal infections. A recent study in mainland China by Yingfang Li and colleagues reported a cryptococcal disease prevalence of 0.21% (1 in 475) among diabetic hospital patients, suggesting that improved blood glucose control may be important in preventing infection.
Watch for influenza-associated aspergillosis (IAA) in critically ill patients
October 31 2017
Around 1 in 6 ICU patients with influenza has a co-infection, but fungal co-infections tend to be underdiagnosed despite being associated with poor outcomes. Radiological signs (cavitary lesions, nodules, air-crescent) and galactomannan testing can identify which patients are likely to benefit from antifungal therapy.
Consider aspergillosis as an alternate diagnosis for smear-negative TB patients
October 24 2017
Overlap in clinical and radiological presentations between tuberculosis (TB) and chronic pulmonary aspergillosis (CPA) makes diagnosis challenging, especially in settings where advanced radiological and laboratory facilities are not available. CPA is likely underdiagnosed in these groups: one recent study of Nigerian TB patients by Rita Oladele and colleagues showed around 19% of HIV negative, smear negative patients had CPA.
