Sensitive detection and quantification of SARS-CoV-2 in saliva.

Saliva has significant advantages as a test medium for detection of SARS-CoV-2 infection in patients, such as ease of collection, minimal requirement of supplies and trained personnel, and safety. Comprehensive validation in a large cohort of prospectively collected specimens with unknown SARS-CoV-2 status should be performed to evaluate the potential and limitations of saliva-based testing. We developed a saliva-based testing pipeline for detection of SARS-CoV-2 nucleic acids using real-time reverse transcription PCR (RT-PCR) and droplet digital PCR (ddPCR) readouts, and measured samples from 137 outpatients tested at a curbside testing facility and 29 inpatients hospitalized for COVID-19.

Hemophagocytic Lymphohistiocytosis in Adults: Associated Diagnoses and Outcomes, a Ten-Year Experience at a Single Institution.

Background: Hemophagocytic lymphohistiocytosis (HLH) is a syndrome of excessive systemic inflammation which causes tissue damage due to abnormal immune system activation and has a high fatality rate even with treatment. HLH continues to be a difficult diagnosis to make because of lack of awareness and its overlap with other illnesses. This disorder is well defined in pediatric patients under the age of 18, but there is also a paucity of data in the adult population.
