Cytokine Growth Factor Rev 2022; 63:34-43. [PMID: 35115233 PMCID: PMC8755267 DOI: 10.1016/j.cytogfr.2022.01.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 01/03/2022] [Accepted: 01/06/2022] [Indexed: 12/14/2022]
Abstract
Recent studies have identified an association between perturbed type I interferon (IFN) responses and the severity of coronavirus disease 2019 (COVID-19). IFNα intervention may normalize the dysregulated innate immunity of COVID-19. However, details regarding its utilization and therapeutic evidence have yet to be systematically evaluated. The aim of this comprehensive review was to summarize the current utilization of IFNα for COVID-19 treatment and to explore the evidence on safety and efficacy. A comprehensive review of clinical studies in the literature prior to December 1st, 2021, was performed to identify the current utilization of IFNα, which included details on the route of administration, the number of patients who received the treatment, the severity at the initiation of treatment, age range, the time from the onset of symptoms to treatment, dose, frequency, and duration as well as safety and efficacy. Encouragingly, no evidence was found against the safety of IFNα treatment for COVID-19. Early intervention, either within five days from the onset of symptoms or at hospital admission, confers better clinical outcomes, whereas late intervention may result in prolonged hospitalization.

[PMID: 34528306 PMCID: PMC8605112 DOI: 10.1002/jcla.24002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Revised: 07/10/2021] [Accepted: 09/03/2021] [Indexed: 01/19/2023] Open
Abstract
Background The coronavirus disease 2019 (COVID‐19) epidemic is still spreading rapidly around the world. Recent cases with prolonged severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) RNA detection have been successively reported, and the phenomenon of false‐negative real‐time polymerase chain reaction (RT‐PCR) results of SARS‐CoV‐2 RNA or “repositive” was also described in COVID‐19 patients. Methods We report a 69‐year‐old female patient with hypertension, suspected lung tumor, and previous history of total hysterectomy for hysteromyoma who presented with moderate COVID‐19 symptoms and was positive for SARS‐CoV‐2 RNA by RT‐PCR when she traveled from the USA to China. Results The patient required second and third re‐hospitalizations due to “repositive” SARS‐CoV‐2 throat swab test results during post‐charge solitary isolation and observation, and serum SARS‐CoV‐2‐IgG decayed rapidly before disappearing on illness Day 139 when the throat swab was still positive. The virus shedding lasted for at least 146 days (the last positive throat swab test result was on illness Day 146, and the first true‐negative test result was on illness Day 151) since her initial positive test. Conclusion Prolonged SARS‐CoV‐2 RNA viral shedding is prone to occur in an immunocompromised host, wherein changes in the host immune status can lead to repeated positive SARS‐CoV‐2 detection. Moreover, the SARS‐CoV‐2‐IgG may decrease rapidly and disappear before virus removal, indicating there may be certain limitations on the protective effect of the SARS‐CoV‐2 antibody, which deserves clinical attention.
