Antifungal susceptibility of invasive Candida bloodstream isolates from the Asia-Pacific region
Abstract
Bloodstream infections caused by Candida species are of increasing importance and associated with significant mortality. We performed a multi-centre prospective observational study to identify the species and antifungal susceptibilities of invasive bloodstream isolates of Candida species in the Asia-Pacific region. The study was carried out over a two year period, involving 13 centers from Brunei, Philippines, Singapore, South Korea, Taiwan, Thailand, and Vietnam. Identification of Candida species was performed at each study center, and reconfirmed at a central laboratory. Susceptibility testing was performed using a commercial broth dilution panel (Sensititre YeastOne YST-010, Thermofisher, United Kingdom) with susceptibility categorisation (S = susceptible, S-DD = susceptible dose-dependent) applied using breakpoints from the Clinical Laboratory Standards Institute. Eight hundred and sixty-one Candida isolates were included in the study. The most common species were C. albicans (35.9%), C. tropicalis (30.7%), C. parapsilosis (15.7%), and C. glabrata (13.6%). Non-albicans species exceeded C. albicans species in centers from all countries except Taiwan. Fluconazole susceptibility was almost universal for C. albicans (S = 99.7%) but lower for C. tropicalis (S = 75.8%, S-DD = 6.1%), C. glabrata (S-DD = 94.9%), and C. parapsilosis (S = 94.8%). Echinocandins demonstrated high rates of in vitro susceptibility (S>99%) against C. albicans, C. tropicalis, and C. parapsilosis This study demonstrates that non-albicans species are the most common isolates from bloodstream infections in most countries in the Asia-Pacific region, with C. tropicalis as the predominant species. Because of the prevalence of reduced susceptibility to fluconazole in non-albicans species, the study indicates that echinocandins should be the antifungal of choice in clinically unstable or high-risk patients with documented candidemia.

The resistant strain of Candida tropicalis might have spread in the Asia-Pacific region.
“These results suggest that this resistant strain might have spread in the Asia-Pacific region.”
The proportion of each Candida species isolated from candidemia cases in Japan is more similar to that in the US and Europe than to the proportion in the Asia-Pacific region.
“Overall, our study shows that the proportion of each Candida species isolated from candidemia cases in Japan is more similar to that in the US and Europe, than to the proportion in the Asia-Pacific region, which may be due to the differences in the climate.”
Tan et al. reported Candida tropicalis to be the second most abundant isolate (30.7%) in the Asia-Pacific region.
“Tan, et al. obtained Candida spp. From seven countries in the Asia-Pacific region and reported C. tropicalis to be the second most abundant isolate (30.7%).22”
The resistance rate of Candida tropicalis for voriconazole was reported to be 14%, 25.6%, and 16.7% in the Asia-Pacific region, China, and Australia, respectively.
“The resistance rate of C. tropicalis for VRCZ was reported to be 14%, 25.6%, and 16.7% in the Asia-Pacific region,22 China26 and Australia,21 respectively.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
