Abstract
Patients with severe West Nile virus and SARS-CoV-2 infections deserve accurate diagnosis of underlying diseases, determining possible anti-interferon autoantibody production, since they must receive antiviral and immunological therapies to enhance antiviral response.
The current study aimed to investigate determinants of severity in a previously healthy patient who experienced 2 life-threatening infections, from West Nile Virus (WNV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV2). During coronavirus disease 2019 (COVID-19) hospitalization he was diagnosed with a thymoma, retrospectively identified as already present at the time of WNV infection. Heterozygosity for p.Pro554Ser in the TLR3 gene, which increases susceptibility to severe COVID-19, and homozygosity for CCR5 c.554_585del, associated with severe WNV infection, were found. Neutralizing anti-interferon (IFN)-α and anti-IFN-ω autoantibodies were detected, likely induced by the underlying thymoma and increasing susceptibility to both severe COVID-19 pneumonia and West Nile encephalitis.
The first line of defense against pathogens relies on innate immunity. Interferons (IFNs) play a key role in the initial antiviral immune response, binding to cell surface receptors and activating the expression of IFN-stimulated genes. Many inborn errors of immunity with an altered type I IFN-related response are associated with severe viral diseases [1].
Patients with severe coronavirus disease 2019 (COVID-19) have reduced IFN-mediated antiviral response, along with massive proinflammatory cytokine production [2]. Moreover, some germline loss-of-function variants in the type I IFN signaling pathway have been described in 2%–3% of severe life-threatening severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections [3]. Moreover, about 15% of life-threatening cases of COVID-19 infection have been related to neutralizing autoantibodies against IFN-ω and/or IFN-α. They can neutralize low (100 pg/mL), intermediate (1 ng/mL), or high (10 ng/mL) concentrations of type I IFNs, impairing their ability to block SARS-CoV-2 infection [4]. Autoantibodies neutralizing type I IFNs have been found in patients with systemic lupus erythematosus, in nearly all patients with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy, and in almost 60% of patients with thymoma and myasthenia gravis [5]. Moreover, these autoantibodies are found in a minority of uninfected people aged >70 years (∼4%) but can also be found in younger people from the general population (0.18% between 18 and 69 years of age) [6]. Therefore, they should be investigated when an atypical infectious history is present even in patients without an underlying pathology.
West Nile virus (WNV) is an RNA virus causing a neuroinvasive disease in <1% of patients. Variants impairing the IFN signaling or chemokine receptors were hypothesized as possible risk factors [7], and a recent meta-analysis confirmed the role of CCR5Δ32 variant in severe WNV infection [8].
We describe a peculiar combination of genetic background and acquired autoantibody production predisposing to both severe West Nile and SARS-CoV-2 infections, suggesting crucial clinical implications in the identification and management of these patients.
MATERIALS AND METHODS
The research immunological and genetic studies were performed in line with the principles of the Declaration of Helsinki.
Genomic DNA Extraction From Peripheral Blood
Genomic DNA was extracted using Maxwell DNA blood kit (Promega) following the manufacturer's instructions on a Maxwell automatic platform.
Genomic DNA Extraction From Formalin-Fixed, Paraffin-Embedded Thymoma Tissue
Genomic DNA extraction from formalin-fixed, paraffin-embedded (FFPE) tissue sections of thymoma after slide scraping of FFPE-selected tumoral areas (100%) was performed using Maxwell RSC DNA FFPE Kit (Promega) following the manufacturer's instructions.
Quantification of Extracted DNA
DNA quantification were assessed using a Qubit Fluorometer with double-stranded DNA (dsDNA) HS Assay Kit for Qubit and dsDNA BR Assay Kit for Qubit (Thermo Fisher Scientific, Wilmington, Delaware).
Next-Generation Sequencing
Whole exome sequencing was performed starting from 100 ng of genomic DNA. Library preparation was performed using SureSelect XT Low Input kit (Agilent). Target enrichment was performed through SureSelect Human All Exon V7 probes (Agilent). The libraries were sequenced on the NovaSeq 6000 platform, 2 × 150 bp (Illumina). Reads alignment and variant calling were performed by Dynamic Read Analysis for GENomics (DRAGEN) on BaseSpace Sequence Hub (Illumina) pipelines. BAM files were visualized with Integrative Genome Viewer software (Broad Institute). Variant annotation and prioritization were conducted using the eVai (EnGenome) tool allowing manually filtered variants, based on different sets of filters with variable stringency: high-quality (pass all quality filters) nonsynonymous variants, population frequency (minor allele frequency <2% or <1%), in silico gene panels, consequence/effect, and inheritance mechanism. The remaining variants were classified according to the American College of Medical Genetics (ACMG) standard, in silico predictions, and experimental data in the literature. Candidate variants with unknown significance (class 3), likely pathogenetic (class 4), or pathogenetic (class 5) were included in the study.
Proliferative Response Assays
Peripheral blood mononuclear cells isolated by Ficoll gradient were cultured in X-VIVO 15 (Lonza) at 5% of human sera (EuroClone S.p.A.) alone or in the presence of polyclonal or antigenic stimuli. Tritiated thymidine was added to the medium 16–18 hours before the end of the culture. The proliferation of the activated lymphocytes was measured as count per minute by MicroBeta Counter (Trilux Perkin Elmer Life Sciences) and reported as stimulation index ratio between cells stimulated versus the cells cultured without stimuli. Evaluation of proliferative response to spike SARS-CoV-2 protein was performed with SARS-CoV-2 PepTivator peptide pools Prot_S (Miltenyi Biotec).
SARS-CoV-2 Receptor-Binding Domain Antibody Luciferase Immunoprecipitation System Assay
IgG binding to the Wuhan SARS-CoV-2 spike protein receptor-binding domain (RBD) was measured by luciferase immunoprecipitation system using a NanoLuc (Promega) nanoluciferase-tagged recombinant antigen expressed in Expi293F (Thermo Fisher Scientific) eukaryotic cells. In brief, patient serum (1 μL) was incubated with nanoluciferase-RBD (2 million light units equivalents of luciferase activity) in Tris-buffered saline pH7.4 0.5% Tween (TBST) for 1 hour at room temperature in a 96-well plate. Immune complexes were then recovered by adding protein-A sepharose beads (Cytiva) and incubating with shaking for 1 hour at 4°C. To remove unbound antigen, sepharose beads were then washed 5 times by sequential centrifugation, TBST aspiration, and dispensing. After washing, the NanoLuc luciferase substrate (Promega) was added to the plate wells and light emission (single photon counting light units [LUs]) measured over a 2-second time span in a luminometer (Berthold GmbH). Raw data LUs were then converted into arbitrary units using a strongly immunized serum as reference. The assay threshold for positivity was placed at the 99th percentile of values measured in prepandemic control samples (n = 384).
Luciferase Reporter Assay
The plasma blocking activity against type I IFNs (13 IFN-α subtypes, IFN-β, and IFN-ω) was determined with a luciferase reporter assay. HEK293T cells, cultured in Dulbecco’s modified Eagle medium (DMEM; Thermo Fisher Scientific) with 10% fetal bovine serum (FBS), were transfected in the presence of X-tremeGene9 transfection reagent (Sigma-Aldrich) for 24 hours with a human interferon-stimulated response element-luciferase plasmid in the pGL4.45 backbone and a plasmid constitutively expressing Renilla luciferase for normalization (pRL-SV40). Then, cells were left unstimulated or were stimulated with IFNs (IFN-α subtypes [PBL Assay Science], IFN-ω [Peprotech], or IFN-β [Peprotech]) at 1 ng/mL for 16 hours at 37°C in the presence of 10% of healthy control or patient plasma diluted in DMEM with 2% FBS. Luciferase activity was assessed in the Dual-Luciferase Reporter 1000 assay system. Raw luciferase induction was calculated as firefly luciferase activity normalized against Renilla luciferase activity, and this raw luciferase induction was normalized against the median induction of healthy controls without neutralizing autoantibodies.
RESULTS
A 63-year-old man admitted with severe COVID-19 infection, requiring mechanical ventilation, subsequently complicated with sepsis and pulmonary embolism. He slowly recovered after multiple nonspecific therapies (steroids, anakinra, antibiotics). His clinical history was characterized by infectious mononucleosis at 18 years of age, uncomplicated measles at 30 years of age, and chickenpox at 45 years of age (Figure 1A).

Remarkably, his past history revealed a life-threatening West Nile encephalitis at age 58 years. During this hospitalization, thorax CT scan identified a 3-cm paracardiac mass, which had increased up to 5 cm at the time of COVID-19 pneumonia (Figure 1B–D).
Considering the severe evolution of both infections (WNV and SARS-CoV-2) in the absence of other clear predisposing factors, despite age, genetic analysis was performed for the patient (I.1).
Whole exome sequencing (WES) analysis revealed the presence of 2 variants, both confirmed by Sanger sequencing—a heterozygous c.1660C > T rare variant on TLR3 (NM_003265.2; rs121434431), with a 0.007 frequency in the European non-Finnish (gnomAD v2.1.1) and causing the missense change p.Pro554Ser (Figure 2A), classified as “likely pathogenic” according to ACMG. This specific TLR3 variant has already been described in literature to be biochemically deleterious in the heterozygous state [3].

TLR3 is a nucleic acid sensor that recognizes viral dsRNA and induces the activation of the innate immune response and the production of type I interferons. On the other hand, the patient also displayed the homozygous c.554_585del variant in CCR5 (NM_000579.3; rs333) with a 1.09% frequency in the European non-Finnish population (gnomAD v2.1.1), causing the frameshift p.Ser185IlefsTer32 (Figure 2A). The ClinVar database defines the variant as benign because it is protective for human immunodeficiency virus (HIV) infection, but it is also reported as a risk factor affecting the clinical course of WNV infection [9], and the Leiden Open Variation Database classifies it as “pathogenic” because it affects the function of the gene.
Thus, the genetic study was extended to the patient's daughter (II.1) and wife (I.2), who experienced COVID-19 in a milder form. Only the daughter was found as a carrier for the CCR5 deletion and the p.Pro554Ser variant on TLR3 (Figure 2A).
Both I.1 and II.1 did not display major immunological abnormalities: Plasma immunoglobulins and specific antibody responses to previous infections/vaccinations, lymphocyte subsets on peripheral blood, and proliferative response in vitro to mitogens and antigens (alloantigens, Candida, tetanus toxoid, herpes simplex virus, cytomegalovirus) were normal. The patient (I.1) showed only mild reduction of total B-cell count (90 cells/μL [normal range, 110–570 cells/μL) and inversion of CD4:CD8 ratio (Supplementary Table 1). Moreover, both I.1 and II.1 developed adequate T-cell proliferative response in vitro (Figure 2B) and specific antibodies (anti-RBD) (Figure 2C) toward SARS-CoV-2.
Due to the absence of molecular etiology for severe COVID-19, we questioned whether other factors could induce such a severe clinical evolution. The answer came from the mediastinal mass, histologically diagnosed as type AB thymoma, which was metabolically active (Figure 1D).
The genomic profile of the tumor was analyzed through WES, and no candidate variants were identified. Considering the risk of autoantibody production related to thymoma, we demonstrated the presence of autoantibodies neutralizing 1 ng/mL IFN-α and anti-IFN-ω autoantibodies in the patient (not in the daughter), even 6 months after thymectomy (Figure 2D). Thus, these autoantibodies represented for the patient an additional risk factor for both severe COVID-19 and invasive WNV infections. Although they are more commonly found in older people, in this case the patient was respectively 58 and 63 years old when he suffered from these conditions, emphasizing the importance of the detection of these autoantibodies in this setting.
DISCUSSION
The reported clinical case represents a unique example of combined genetic and acquired risk factors for severe COVID-19 and WNV infection. Indeed, our patient harbors the heterozygous (p.Pro554Ser) missense variant in the TLR3 gene and is homozygous for the CCR5Δ32 deletion, but he was also affected by a thymoma causing production of anticytokine antibodies.
TLR3 deficiency due to the p.Pro554Ser variant confers an autosomal dominant predisposition to herpes simplex virus encephalitis and to COVID-19 infection, with incomplete clinical penetrance [3]. The TLR3–IFN-α pathway is recognized to be relevant also for the response to WNV encephalitis. Indeed, NS1 protein of WNV inhibits TLR3 signal transduction to facilitate viral expansion [10]. TLR3 knockout mice have increased viral burden into the brain, compared to wild type [11]. Additionally, in humans, downregulation of TLR3 on macrophages in elderly persons seems to be related to an increased risk of impaired response to WNV [12].
The genetic analysis identified the TLR3 p.Pro554Ser variant in the patient, who experienced severe WNV encephalitis and severe COVID-19, and in his daughter, who had a mild COVID-19 infection, supporting an incomplete clinical penetrance.
The patient was even homozygous for the CCR5Δ32 variant, which is known to confer resistance to HIV infection and is associated with severe course of WNV infection [8]. Similarly, Ccr5–/– WNV-infected mice display impaired leukocyte trafficking toward the brain, reduced capacity of viral control, increased disease severity, and higher mortality rates than Ccr5 wild-type mice [13]. These data support the role of CCR5 as a protective factor against WNV infection. However, CCR5Δ32’s contribution to the risk of contracting SARS-CoV-2 infection and its severe evolution remains still elusive in literature [14, 15]. Thus, lack of CCR5 expression may have different roles depending on the pathogen.
Our patient's genotype is a combination of factors without a certain predisposing effect toward the viruses causing the 2 life-threatening infections experienced (Supplementary Table 1).
A possible explanation arose from the mediastinal mass already identified at the time of WNV infection and later diagnosed as a thymoma. Indeed, thymoma can induce the production of several autoantibodies due to impaired AIRE expression and central tolerance within the lesion [16], and WNV infection has been reported in the setting of Good syndrome [17].
Despite the absence of other autoimmune manifestation, typical of thymoma (eg, myasthenia gravis), the patient produced anti-IFN-α and anti-IFN-ω autoantibodies, which contributed to the severe evolution of SARS-CoV-2 infection and might have favored invasive WNV infection. The odds ratio for WNV disease in individuals with these autoantibodies relative to those without them in the general population is much higher when both anti-IFN-α and anti-IFN-ω are present, even if at low concentration [18]. Moreover, the odds ratio for critical COVID-19 was similarly higher in the subset of patients with positivity for both autoantibodies [19].
This case suggests that autoantibodies neutralizing type I IFNs should be investigated in patients with thymoma and in individuals with severe viral diseases known to be associated with these autoantibodies (eg, varicella zoster virus disease [20], critical influenza pneumonia [21], Middle East respiratory syndrome [22]) in order to ensure an early diagnosis and targeted treatment favoring better outcomes. These autoantibodies represent acquired risk factors that, importantly, do not fade after thymectomy (Figure 2D). Hence, this should be considered a permanent vulnerability, despite competent adaptive immunity and full immunization against SARS-CoV-2. Interestingly, in a mouse model of WNV infection, administration of neutralizing antibody to anti-IFN receptor before viral challenge resulted in enhanced susceptibility to WNV [23]. Moreover, a recent large international cohort study showed that 40% of patients with WNV encephalitis carry autoantibodies neutralizing IFN-α and/or IFN-ω [18].
Overall, this is an example of how genetic and acquired factors may increase susceptibility and severity of specific infections, as similarly described for a patient affected by severe COVID-19 with both TLR7 deficiency and anti-IFN autoantibodies [24]. Indeed, the association of the heterozygous missense TLR3 variant, the homozygous CCR5Δ32 deletion, and the production of anti-IFN type I antibodies likely contributed to the severe course of COVID-19 and WNV infection in this patient.
In conclusion, patients with such an immunological background deserve dedicated management due to their high risk of poor outcome related to a delayed clearance of the virus. This observation may pave the way to the application, in similar cases, of therapies with antivirals or IFNs not targeted by autoantibodies. Further cohort studies are needed to elucidate the effectiveness of these therapeutic approaches in anticipating the viral clearance.
