Abstract

A patient with azole-refractory thrush-esophagitis responded initially to caspofungin, but the treatment eventually failed. In a murine model, caspofungin was effective against two early isolates for which the MICs of caspofungin were low, but it was less effective against a late isolate for which the MIC of caspofungin was greater. We concluded that there is a correlation between in vivo failure and rising in vitro caspofungin MICs.

  • Reports of echinocandin resistance in patients with infections due to C. albicans, C. glabrata, C. tropicalis, and C. krusei are rising.

    “However, reports of echinocandin resistance in patients with infections due to C. albicans, C. glabrata, C. tropicalis, and C. krusei are rising [111–116].”
  • The frequency of diagnostic test ordering, especially blood cultures, and the type of blood culture systems may impact incidence rates in laboratory-based surveillance.

    “Likewise, the frequency of diagnostic test ordering, especially of blood cultures, and the type of blood culture systems employed may also impact the incidence rates in laboratory-based surveillance (106, 259).”
  • The isolation of C. glabrata may be increased in some blood culture systems (BacT/Alert versus BACTEC 9240) and in some blood culture media (BACTEC Mycosis IC/F versus BACTEC Plus Aerobic/F medium) over that observed in others.

    “Although most surveillance studies have not specifically addressed the issue of differences among blood culture systems in the isolation of Candida species from blood, the isolation of C. glabrata may be increased in some blood culture systems (BacT/Alert versus BACTEC 9240) and in some blood culture media (BACTEC Mycosis IC/F versus BACTEC Plus Aerobic/F medium) over that observed in others (106,”

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.
