BACKGROUND: Interferons (IFNs) play a crucial role in antiviral immunity. Genetic defects in interferon receptors, IFNs, and auto-antibodies against IFNs can lead to the development of life-threatening forms of infectious diseases like a severe form of COVID-19.
CASE PRESENTATION: A 13-year-old boy with a previously reported homozygous loss-of-function mutation in interferon alpha/beta receptor subunit 1 (IFNAR1) (c.674-2A > G) was diagnosed with severe COVID-19. He had cold symptoms and a high-grade fever at the time of admission. He was admitted to the pediatric intensive care unit after showing no response to favipiravir and being hypoxemic. High-resolution computed tomography (HRCT) scanning revealed lung involvement of 70% with extensive areas of consolidation in both lungs. Antibiotics, interferon gamma (IFN-γ), remdesivir, methylprednisolone pulse, and other medications were started in the patient. However, remdesivir and methylprednisolone pulse were discontinued because of their adverse side effects in the patient. His general condition improved, and a few days later was discharged from the hospital.
CONCLUSION: We reported a patient with severe COVID-19 who had a mutation in IFNAR1. Our finding suggests that patients with IFNAR1 deficiency are prone to severe forms of COVID-19. Besides, IFN-γ therapy may be a potential drug to treat patients with defects in IFN-α/β signaling pathways which needs further investigations.
