Abstract

A multiplexed microarray chip (Immuno-μSARS2) aiming at providing information on the prognosis of the COVID-19 has been developed. The diagnostic technology records information related to the profile of the immunological response of patients infected by the SARS-CoV-2 virus. The diagnostic technology delivers information on the avidity of the sera against 28 different peptide epitopes and 7 proteins printed on a 25 mm² area of a glass slide. The peptide epitopes (12–15 mer) derived from structural proteins (Spike and Nucleocapsid) have been rationally designed, synthesized, and used to develop Immuno-μSARS2 as a multiplexed and high-throughput fluorescent microarray platform. The analysis of 755 human serum samples (321 from PCR+ patients; 288 from PCR– patients; 115 from prepandemic individuals and classified as hospitalized, admitted to intensive-care unit (ICU), and exitus) from three independent cohorts has shown that the chips perform with a 98% specificity and 91% sensitivity identifying RT-PCR+ patients. Computational analysis utilized to correlate the immunological signatures of the samples analyzed indicate significant prediction rates against exitus conditions with 82% accuracy, ICU admissions with 80% accuracy, and 73% accuracy over hospitalization requirement compared to asymptomatic patients’ fingerprints. The miniaturized microarray chip allows simultaneous determination of 96 samples (24 samples/slide) in 90 min and requires only 10 μL of sera. The diagnostic approach presented for the first time here could have a great value in assisting clinicians in decision-making based on the information provided by the Immuno-μSARS2 regarding progression of the disease and could be easily implemented in diagnostics of other infectious diseases.

期刊介绍： ACS Pharmacology & Translational Science publishes high quality, innovative, and impactful research across the broad spectrum of biological sciences, covering basic and molecular sciences through to translational preclinical studies. Clinical studies that address novel mechanisms of action, and methodological papers that provide innovation, and advance translation, will also be considered. We give priority to studies that fully integrate basic pharmacological and/or biochemical findings into physiological processes that have translational potential in a broad range of biomedical disciplines. Therefore, studies that employ a complementary blend of in vitro and in vivo systems are of particular interest to the journal. Nonetheless, all innovative and impactful research that has an articulated translational relevance will be considered. ACS Pharmacology & Translational Science does not publish research on biological extracts that have unknown concentration or unknown chemical composition. Authors are encouraged to use the pre-submission inquiry mechanism to ensure relevance and appropriateness of research.
