Delayed Antibody Response in the Acute Phase of Infection Is Associated with a Lower Mental Component of Quality of Life in Survivors of Severe and Critical COVID-19.

The long-term sequelae of coronavirus disease 2019 (COVID-19) significantly affects quality of life (QoL) in disease survivors. Delayed development of the adaptive immune response is associated with more severe disease and a worse prognosis in COVID-19. The effects of delayed immune response on COVID-19 sequelae and QoL are unknown.

Antimicrobial Therapy as a Risk Factor of Multidrug-Resistant Infection in COVID-19 Patients Admitted to the Intensive Care Unit.

Background: Multidrug-resistant (MDR-Ab) is one of the most important pathogens causing superinfections in COVID-19 patients hospitalised in the intensive care unit (ICU). The occurrence of MDR-Ab superinfection significantly impairs the prognosis of patients in the ICU. Overuse of antibiotics in COVID-19 patients might contribute to the risk of developing MDR-Ab infection.

Anti-SARS-CoV-2 Antibody Status at the Time of Hospital Admission and the Prognosis of Patients with COVID-19: A Prospective Observational Study.

The association between COVID-19 severity and antibody response has not been clearly determined. We aimed to assess the effects of antibody response to SARS-CoV-2 S protein at the time of hospital admission on in-hospital and longitudinal survival. Methods: A prospective observational study in naive hospitalised COVID-19 patients.

Lofgren syndrome in close temporal association with mild COVID-19 - Case report.

Coronavirus infection disease 2019 (COVID-19) has been linked to the development of various autoimmune disorders. Lofgren syndrome, consisting of bilateral pulmonary hilar lymphadenopathy, erythema nodosum and polyarthritis, is a rare autoimmune disease that represents an acute form of sarcoidosis. We present the case of Lofgren syndrome developing in close temporal association with COVID-19.
