Challenges in Diagnosing COVID-19-Associated Pulmonary Aspergillosis in Critically Ill Patients: The Relationship between Case Definitions and Autoptic Data.

Critically ill COVID-19 patients can develop invasive pulmonary aspergillosis (CAPA). Considering the weaknesses of diagnostic tests/case definitions, as well as the results from autoptic studies, there is a debate on the real burden of aspergillosis in COVID-19 patients. We performed a retrospective observational study on mechanically ventilated critically ill COVID-19 patients in an intensive care unit (ICU).

[Frequency and clinical associations of antineutrophil cytoplasmic antibodies. A regional experience].

Serologic and clinical aspects of 50 positives patients for antineutrophil cytoplasmic antibodies (ANCA) have been evaluated (age range 7-94 years, mean age 43 years). 40 (80%) were females. Antineutrophil nuclear antibodies (pANNA), in which the antigenic specificity is unknown, were detected in seventeen patients (34%).
