Abstract

Objectives: Inflammatory markers such as erythrocyte sedimentation rate (ESR) and C‐reactive protein (CRP) are poorly informative about interferon (IFN)‐related disorders. In these conditions, the measure of the interferon score (IS), obtained by measuring the expression of IFN‐stimulated genes, has been proposed. Flow cytometry‐based assays measuring sialic‐acid‐binding Ig‐like lectin 1 (Siglec‐1) expression could be a more practical tool for evaluating IFN‐inflammation. The study compared Siglec‐1 measures with IS and other inflammatory indexes. We compared Siglec‐1 measures with IS and other inflammatory indexes in real‐world paediatric rheumatology experience. Methods: We recruited patients with immuno‐rheumatological conditions, acute infectious illness and patients undergoing orthopaedic surgery as controls. Siglec‐1 expression was measured in all samples, and IS, ESR and CRP were also recorded if available. Results: Overall, 98 subjects were enrolled in the study, with a total of 104 measures of Siglec‐1. Compared with IS, Siglec‐1 expression showed good accuracy (86.0%), specificity (72.7%) and sensitivity (85.7%). The measure of the percentage of Siglec‐1‐positive cells performed best at low levels of IFN‐inflammation, while the measure of mean fluorescence intensity performed best at higher levels. Ex vivo studies on IFN‐stimulated monocytes confirmed this behaviour. There was no link between Siglec‐1 expression and either ESR or CRP, and positive Siglec‐1 results were found even when ESR and CRP were normal. A high Siglec‐1 expression was also recorded in subjects with acute infections. Conclusion: Siglec‐1 measurement by flow cytometry is an easy tool to detect IFN‐related inflammation, even in subjects with normal results of common inflammation indexes. [ABSTRACT FROM AUTHOR]

Abstract

Inborn errors of immunity (IEI) associated with immune dysregulation are not sufficiently addressed in shared recommendation, resulting in delayed diagnosis and high morbidity. The availability of precision medicine for some of these immune defects makes it urgent to evaluate effective strategies to diagnose and treat such defects before the occurrence of severe complications. A diagnosis of an IEI in these patients enabled the use of a more specific treatment in most cases, and these have the potential to prevent further disease progression. We studied immune dysregulation diseases in 30 patients with autoimmune or allergic phenotypes, exploiting data from clinics and immunophenotype, genetic and transcriptome investigations, and 6 of them were diagnosed with a monogenic disorder. Our results confirm that a non-negligible number of children with IEIs may present with signs and symptoms of immune dysregulation and share many features with common multifactorial immune conditions. Reaching a genetic diagnosis becomes more likely in the presence of multiple clinical manifestations, especially when in association with abnormalities of lymphocytes subsets and/or immunoglobulins levels. Moreover, 5 of 6 patients that obtained a diagnosis of monogenic disorder received precision therapy, in four cases with a good or moderate response. [ABSTRACT FROM AUTHOR]

Abstract

Il lupus eritematoso sistemico (LES) rappresenta una complessa patologia multisistemica, all’interno del cui universo si possono spesso individuare eventi patogenetici diversi ma riconducibili a quadri clinici sovrapponibili. Una possibile caratteristica comune può considerarsi l’utilizzo improprio della risposta immunitaria agli acidi nucleici. Per comprendere il ruolo di questo tipo di risposta, ci siamo concentrati sullo studio delle Interferonopatie di tipo I, un gruppo di malattie monogeniche di recente definizione, causate da alterazioni nel meccanismo di riconoscimento e metabolismo degli acidi nucleici e caratterizzate da un’aberrante stimolazione della via degli interferoni di tipo I. Queste malattie sono clinicamente eterogenee ma mostrano alcune sovrapposizioni con il lupus, la sindrome di Aicardi-Goutières ed alcune infezioni virali congenite. Lo studio di questi modelli monogenici risulta di grande interesse soprattutto per indirizzare il trattamento terapeutico verso l’utilizzo di farmaci attivi a livello della via dell’interferone. Nel nostro laboratorio è stato descritto il caso di Simone, nato con una grave epatopatia risoltasi poi spontaneamente, che ha successivamente sviluppato alcuni sintomi lupus-like quali artrite, glomerulonefrite, lipodistrofia, anticorpi anti-DNA e geloni. Le analisi genetiche condotte per le più comuni malattie auto-infiammatorie sono risultate negative, e solo in seguito ad analisi di esoma è stata identificata una nuova mutazione nel gene DNASI2. Questo gene codifica per un’endonucleasi lisosomiale, il cui deficit porta alla mancata digestione degli acidi nucleici, che persistono all’interno della cellula e causano la continua attivazione della via interferonica. Esistono infatti numerose evidenze a dimostrazione del ruolo causale della DNAsi2 nella patologia di Simone, e, insieme alle prove funzionali eseguite grazie alla collaborazione con Yanick Crow, che ha descritto la stessa malattia in una seconda famiglia, abbiamo dimostrato che il difetto di DNAsi2 rappresenta una nuova interferonopatia monogenica. In seguito a questa conoscenza, è stata rimodulata la terapia con farmaci indirizzati verso il meccanismo patogenetico: l’inibitore di JAK1/2, Ruxolitinib, è stato utilizzato in combinazione con due antimalarici, Mepacrina ed Idrossiclorochina, portando ad un generale miglioramento della qualità di vita di Simone. Durante questo studio, inoltre, sono stati messi a punto due strumenti che risultano interessanti per la valutazione e l’ottimizzazione di trattamenti attivi nella via interferonica: l’analisi della signature interferonica (SI), che misura nel sangue periferico l’espressione dei geni indotti dall’interferone, permettendo di capire se ci troviamo in presenza di un’alterazione interferonica e quindi di un’interferonopatia, ed il test di infezione di fibroblasti con E. coli, attraverso cui si può valutare l’attivazione della via in seguito ad un sovraccarico di DNA batterico. Considerando le conoscenze acquisite durante questo studio, e la crescente disponibilità di farmaci attivi a livello della via interferonica, abbiamo condotto uno screening con SI per identificare altri soggetti con patologie dipendenti dall’eccesso di risposta interferonica. La nostra proposta si riassume in una traccia di “protocollo diagnostico terapeutico assistenziale” (PDTA) per lo studio delle interferonopatie all’interno dell’IRCCS Burlo Garofolo.

Abstract

Background COPA syndrome is a rare hereditary inflammatory disease caused by mutations in the gene encoding the coatomer protein subunit alpha, causing excessive production of type I interferon. This case is a reminder for the general paediatrician, highlighting the relevance of the association between arthritis and lung involvement in toddlers. Case presentation We report the case of a 2-year-old girl with intermittent limping and joint pain. Her family history was relevant for a Still disease with lung involvement in the mother. Physical examination showed moderate wrist swelling. Laboratory findings on admission showed an increase in inflammatory markers, positive rheumatoid factor, antibodies antinuclear antibody (ANA) and cyclic citrullinated peptide (anti-CCP). Wrists’ ultrasound documented synovial thickening, and chest X-rays showed an unexpected severe interstitial pneumopathy. Genetic testing confirmed the diagnosis of a heterozygous mutation of the COPA gene in c.841C > T (p.R281W). Janus kinase treatment was started (baricitinib, 4 mg daily per os) with a remarkable improvement in limping and joint pain after two weeks. Conclusions In cases of recurrent arthritis with family history and multiple involvement organs, a genetic disorder should be suspected and genetic testing should be performed. Furthermore, this case suggests that therapy with jak inhibitors may be effective and safe in interferonopathies.

Abstract

Primary immunodeficiencies (PIDs) are a large and growing group of disorders commonly associated with recurrent infections. However, nowadays, we know that PIDs often carry with them consequences related to organ or hematologic autoimmunity, autoinflammation, and lymphoproliferation in addition to simple susceptibility to pathogens. Alongside this conceptual development, there has been technical advancement, given by the new but already established diagnostic possibilities offered by new genetic testing (e.g., next-generation sequencing). Nevertheless, there is also the need to understand the large number of gene variants detected with these powerful methods. That means advancing beyond genetic results and resorting to the clinical phenotype and to immunological or alternative molecular tests that allow us to prove the causative role of a genetic variant of uncertain significance and/or better define the underlying pathophysiological mechanism. Furthermore, because of the rapid availability of results, laboratory immunoassays are still critical to diagnosing many PIDs, even in screening settings. Fundamental is the integration between different specialties and the development of multidisciplinary and flexible diagnostic workflows. This paper aims to tell these evolving aspects of immunodeficiencies, which are summarized in five key messages, through introducing and exemplifying five clinical cases, focusing on diseases that could benefit targeted therapy.

Abstract

Background Recurrent aphthous stomatitis with systemic signs of inflammation can be encountered in inflammatory bowel disease, Behçet’s disease (BD), Systemic Lupus Erythematosus (SLE). In addition, it has been proposed that cases with very early onset in childhood can be underpinned by rare monogenic defects of immunity, which may require targeted treatments. Thus, subjects with early onset recurrent aphthous stomatitis receiving a clinical diagnosis of BD-like or SLE-like disease may deserve a further diagnostic workout, including immunologic and genetic investigations. Objective To investigate how an immunologic, genetic and transcriptomics assessment of interferon inflammation may improve diagnosis and care in children with recurrent aphthous stomatitis with systemic inflammation. Methods Subjects referred to the pediatric rheumatologist for recurrent aphthous stomatitis associated with signs of systemic inflammation from January 2015 to January 2020 were enrolled in the study and underwent analysis of peripheral lymphocyte subsets, sequencing of a 17-genes panel and measure of interferon score. Results We enrolled 15 subjects (12 females, median age at disease onset 4 years). The clinical diagnosis was BD in 8, incomplete BD in 5, BD/SLE overlap in 1, SLE in 1. Pathogenic genetic variants were detected in 3 patients, respectively 2 STAT1 gain of function variants in two patients classified as BD/SLE overlap and SLE, and 1 TNFAIP3 mutation (A20 haploinsufficiency) in patients with BD. Moreover 2 likely pathogenic variants were identified in DNASE1L3 and PTPN22, both in patients with incomplete BD. Interferon score was high in the two patients with STAT1 GOF mutations, in the patient with TNFAIP3 mutation, and in 3 genetic-negative subjects. In two patients, the treatment was modified based on genetic results. Conclusions Although recurrent aphthous stomatitis associated with systemic inflammation may lead to a clinical diagnosis of BD or SLE, subjects with early disease onset in childhood deserve genetic investigation for rare monogenic disorders. A wider genetic panel may help disclosing the genetic background in the subset of children with increased interferon score, who tested negative in this study.

Abstract

Interferon-stimulated genes (ISGs) are a set of genes whose transcription is induced by interferon (IFN). The measure of the expression of ISGs enables calculating an IFN score, which gives an indirect estimate of the exposition of cells to IFN-mediated inflammation. The measure of the IFN score is proposed for the screening of monogenic interferonopathies, like the Aicardi-Gouti&egrave, res syndrome, or to stratify subjects with systemic lupus erythematosus to receive IFN-targeted treatments. Apart from these scenarios, there is no agreement on the diagnostic value of the score in distinguishing IFN-related disorders from diseases dominated by other types of cytokines. Since the IFN score is currently measured in several research hospitals, merging experiences could help define the potential of scoring IFN inflammation in clinical practice. However, the IFN score calculated at different laboratories may be hardly comparable due to the distinct sets of IFN-stimulated genes assessed and to different controls used for data normalization. We developed a reliable approach to minimize the inter-laboratory variability, thereby providing shared strategies for the IFN signature analysis and allowing different centers to compare data and merge their experiences.

Abstract

More and more findings suggest that neurological disorders could have an immunopathological cause. Thus, immune-targeted therapies are increasingly proposed in neurology (even if often controversial), as anakinra, inhibiting IL-1 for febrile inflammatory illnesses, and JAK inhibitors for anti-interferons treatment. Precision medicine in neurology could be fostered by a better understanding of the disease machinery, to develop a rational use of immuno-modulators in clinical trials. In this review, we focus on monogenic disorders with neurological hyper-inflammation/autoimmunity as simplified “models” to correlate immune pathology and targeted treatments. The study of monogenic models yields great advantages for the elucidation of the pathogenic mechanisms that can be reproduced in cellular/animal models, overcoming the limitations of biological samples to study. Moreover, monogenic disorders provide a unique tool to study the mechanisms of neuroinflammatory and autoimmune brain damage, in all their manifestations. The insight of clinical, pathological, and therapeutic aspects of the considered monogenic models can impact knowledge about brain inflammation and can provide useful hints to better understand and cure some neurologic multifactorial disorders.

Abstract

Microbial nucleic acid recognition serves as the major stimulus to an antiviral response, implying a requirement to limit the misrepresentation of self nucleic acids as non-self and the induction of autoinflammation. By systematic screening using a panel of interferon-stimulated genes we identify two siblings and a singleton variably demonstrating severe neonatal anemia, membranoproliferative glomerulonephritis, liver fibrosis, deforming arthropathy and increased anti-DNA antibodies. In both families we identify biallelic mutations in DNASE2, associated with a loss of DNase II endonuclease activity. We record increased interferon alpha protein levels using digital ELISA, enhanced interferon signaling by RNA-Seq analysis and constitutive upregulation of phosphorylated STAT1 and STAT3 in patient lymphocytes and monocytes. A hematological disease transcriptomic signature and increased numbers of erythroblasts are recorded in patient peripheral blood, suggesting that interferon might have a particular effect on hematopoiesis. These data define a type I interferonopathy due to DNase II deficiency in humans., Nucleic acid sensing is important to ensure that an innate immune response is only mounted against microbial nucleic acid. Here, the authors identify loss-of-function mutations in the DNASE2 gene that cause type I interferon-mediated autoinflammation due to enhanced systemic interferon signaling.

Abstract

The story of antimalarials as antinflammatory drugs dates back several centuries. Chinin, the extract of the Cinchona bark, has been exploited since the 18th century for its antimalarial and antifebrile properties. Later, during the Second World War, the broad use of antimalarials allowed arguing their antirheumatic effect on soldiers. Since then, these drugs have been broadly used to treat Systemic Lupus Erythematosus, but, only recently, have the molecular mechanisms of action been partly clarified. Inhibitory action on vacuole function and trafficking has been considered for decades the main mechanism of the action of antimalarials, affecting the activation of phagocytes and dendritic cells. In addition, chloroquine is also known as a potent inhibitor of autophagy, providing another possible explanation of its antinflammatory action. However, much attention has been recently devoted to the action of antimalarials on the so-called cGASSTING pathway leading from the sensing of cytoplasmic nucleic acids to the production of type I interferons. This pathway is a fundamental mechanism of host defence, since it is able to detect microbial DNA and induce the type I interferon-mediated immune response. Of note, genetic defects in the degradation of nucleic acids lead to inappropriate cGAS-STING activation and inflammation. These disorders, called type I interferonopathies, represent a valuable model to study the antinflammatory potential of antimalarials. We will discuss possible development of antimalarials to improve the treatment of type I interferonopathies and likely multifactorial disorders characterised by interferon inflammation, such as Systemic Lupus Erythematosus.

Abstract

Alteration in the ubiquitin-proteasome system results in human disorders with neurological and/or autoinflammatory presentation. Haploinsufficiency of PSMD12, which encodes a subunit of the core component of the proteasome, causes Stankiewicz-Isidor syndrome (STISS), characterized by intellectual disability, autism spectrum disorder, craniofacial dysmorphisms, with or without other congenital anomalies, and autoinflammation. We described six patients (four adults) from two unrelated families carrying a known p.(Arg289*) or a novel p.(Tyr111*) PSMD12 variant. Portraying a completely penetrant condition with inter- and intra-familiar clinical variability, all individuals presented with developmental delay, intellectual disability, craniofacial, and skeletal anomalies. Novel findings in our cohort included unilateral ectopic fingernail, cholesteatoma, oligodontia, and the occurrence of an ovarian teratoma. Most subjects had acne, short stature, and developed obesity since late childhood. Eating behavior was reported. Good sociality and behavioral concern emerged as well. None presented clinical manifestations of autoinflammation and the detected IFN-I signature perturbations were not specific. Together with a complete literature review, we expanded the clinical spectrum of STISS, highlighting the relevance of inherited variants, and discussing challenges in diagnosis and management. We finally consider the intriguing role of PSMD12 in human development and propose to index "onychoheterotopia" among the Human Phenotype Ontology terms., (© 2024 The Author(s).

Abstract

Objectives: The interferon score (IS) quantifies the expression of interferon-stimulated genes in peripheral blood, providing an indirect estimate of interferon-mediated inflammation in rheumatological disorders. This study explores the clinical significance of IS among a cohort of patients affected by juvenile idiopathic arthritis (JIA) and its relevance to disease stratification and prognosis., Methods: All patients referred to the Rheumatology Service of the Institute for Maternal and Child Health IRCCS Burlo Garofolo, Trieste, Italy, with a diagnosis of JIA (2001 ILAR criteria) were consecutively recruited. Systemic JIA was excluded. Demographic, clinical and laboratory data were collected for each patient in a structured database. Categorical variables were expressed as numbers (%) and compared by the χ2 test or Fisher's exact test. Principal Component Analysis (PCA) was performed with clinical and laboratory data., Results: Forty-four patients were recruited (35 F, 9 M): 19 polyarticular, 13 oligoarticular, 6 oligoarticular-extended, 5 psoriatic and 1 enthesitis-related arthritis. Sixteen had a positive IS (≥3). Increased IS correlated with a higher number of involved joints ≥5 (p=0.013), increased erythrocyte sedimentation rate (ESR) (p=0.026) and hypergammaglobulinaemia (p=0.003). PCA highlighted a subgroup of patients who shared high levels of IS, ESR, C-reactive protein, hypergammaglobulinaemia, JADAS-27, polyarticular involvement and family history of autoimmunity., Conclusions: Although based on a small case series, our results may support the role of IS in better defining a subgroup of JIA subjects with stronger autoimmune features. The possible relevance of these results for therapeutic stratification remains to be explored.
