ADA2-deficient cells exhibit increased levels of cell death and metabolic disturbances.

Cell death discovery2026 Mar 23

Deficiency of adenosine deaminase 2 (DADA2) causes a complex phenotype of autoinflammation and immunodeficiency. Bone marrow failure is often refractory to treatment with tumour necrosis factor-alpha (TNF-alpha) inhibitors and additional treatment options are needed. However, the pathomechanisms underlying the disease remain incompletely understood. The aim of this study was to examine the viability and metabolic profile of ADA2-deficient cells and to characterise the activity of different cell death pathways to advance the mechanistic understanding of DADA2. By flow cytometry and western blot, we showed that ADA2-/- U-937 cells and PBMCs from DADA2 patients showed significantly elevated levels of cell death compared with cells expressing wild-type ADA2. Viability of ADA2-deficient cells was not improved by inhibitors of apoptosis, necroptosis, pyroptosis and ferroptosis. Blocking of TNF-alpha, type I interferon and STING signalling as well as reintroduction of wild-type ADA2 protein did not rescue the cell death phenotype in vitro. ADA2-deficient cells had an aberrant morphology with increased cell size and granularity and were impaired in their proliferative capacity. To identify the cause of the impaired viability, we performed 13C glucose tracer metabolomics experiments which revealed disturbances in the pentose phosphate pathway of ADA2-deficient cells. This tended to be associated with increased exposure to intracellular reactive oxygen species that was attenuated in the PBMCs of a DADA2 patient measured after successful hematopoietic stem cell transplantation. Collectively, our findings established increased levels of cell death as a possible pathomechanism of DADA2 and showed that the absence of ADA2 leads to an impairment of the pentose phosphate pathway which may account for the cellular vulnerability of ADA2-deficient cells.

Hematopoietic Stem Cell Transplantation in Rheumatic Diseases.

International journal of rheumatic diseases2026 Mar

Hematopoietic stem cell transplantation (HSCT) is an emerging therapeutic strategy for severe autoimmune rheumatic diseases (AIRD) where conventional therapies often fail to achieve long-term remission. This review focuses on the role of HSCT in specific AIRD, including systemic sclerosis (SSc), systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), deficiency of adenosine deaminase 2 (DADA2), antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, Takayasu arteritis (TA), and juvenile idiopathic arthritis (JIA). The objective was to evaluate the efficacy, immunological mechanisms, patient selection criteria, conditioning regimens, and outcomes of HSCT in the management of these specific AIRD, with a focus on systemic sclerosis-associated interstitial lung disease (SSc-ILD). A comprehensive literature review was conducted, analyzing clinical trials, observational studies, and preclinical research on HSCT in the following AIRD: SSc, SLE, RA, DADA2, ANCA-associated vasculitis, TA, and JIA. The review examined pulmonary outcomes, immune reconstitution, CD34+ cell selection, and post-transplant immunosuppression. Keywords used in the search included SSc, SLE, RA, DADA2, ANCA-associated vasculitis, Takayasu arteritis, and JIA. HSCT has demonstrated promising outcomes, particularly in diffuse cutaneous SSc with ILD improvement and in refractory cases of SLE, RA, and JIA. In DADA2, HSCT can reverse hematological, immunological, and vascular phenotypes. While effective in some cases of ANCA-associated vasculitis and TA, relapses and complications remain a concern. Immunological benefits include the regeneration of a self-tolerant immune system. However, early transplant-related mortality (TRM) necessitates careful patient selection and reduced toxicity conditioning. HSCT offers a transformative approach for select patients with refractory SSc, SLE, RA, DADA2, ANCA-associated vasculitis, TA, and JIA, achieving long-term, drug-free remission in some. Future research should optimize conditioning protocols, refine patient selection, and assess long-term outcomes to maximize HSCT benefits and minimize risks.

Targeting cytokine pathways: the role of biologics in autoinflammatory disorders.

Expert review of clinical immunology2026 Jan

Autoinflammatory diseases are inherited disorders of innate immunity, broadly classified into inflammasomopathies, interferonopathies, and complement-mediated disorders. They are characterized by dysregulated cytokine signaling - particularly IL-1, IL-6, TNF, type I interferon, and the JAK-STAT pathway-and are increasingly managed with molecular targeted therapies. Prototypical entities include familial Mediterranean fever (FMF), TNF receptor - associated periodic syndrome (TRAPS), and cryopyrin-associated periodic syndromes (CAPS). Other conditions - notably mevalonate kinase deficiency (MKD/HIDS), deficiency of adenosine deaminase 2 (DADA2), haploinsufficiency of A20 (HA20), OTULIN-related autoinflammatory syndromes, and proteasome-associated autoinflammatory syndromes (PRAAS) - are now recognized as biologic-responsive diseases. This review summarizes molecular mechanisms and therapeutic strategies, focusing on IL-1 blockade with anakinra, canakinumab, and rilonacept, as well as IL-6 and TNF inhibitors, integrating evidence from clinical trials and real-world studies. IL-1 inhibition has transformed the management of inflammasome-mediated diseases, enabling glucocorticoid-free remission and reducing amyloidosis risk. TNF inhibitors remain standard for vasculopathic disorders such as DADA2, while IL-6 blockade and JAK inhibitors are options in selected refractory cases. The recognition of novel syndromes, including HA20, OTULIN deficiency, and PRAAS, has broadened the therapeutic landscape, and next-generation biologics may further enable personalized treatment.

Hepatic Vascular Involvement in Adenosine Deaminase 2 Deficiency (DADA2): Case Reports and Literature Review.

Diagnostics (Basel, Switzerland)2026 Jan 07

Background and Clinical Significance: Deficiency of Adenosine Deaminase 2 (DADA2) is a rare monogenic vasculopathy characterised by systemic inflammatory and immunodeficiency features. Although neurological and haematological manifestations are well-documented, hepatic vascular involvement remains underappreciated. This report aims to describe the clinical and imaging characteristics of hepatic vascular involvement in a patient with DADA2 and to illustrate the evolution of hepatic lesions during long-term Etanercept therapy. In addition, we provide a synthesis of the available evidence on hepatic manifestations in DADA2, emphasising vascular pathology, clinical presentation, and therapeutic implications. Case Presentation: We describe a girl with early-onset DADA2 presenting with recurrent systemic inflammation, hypogammaglobulinaemia, vasculopathy, and two childhood strokes, followed by the development of multiple FNH-like hepatic nodules on CEUS and MRI with persistently elevated GGT. Genetic testing confirmed biallelic ADA2 mutations, and treatment with Etanercept led to sustained clinical stabilisation and marked regression of liver lesions over a nine-year follow-up period. Her older sister, carrying the same mutations, showed a milder phenotype without hepatic involvement but experienced a mesenteric vascular event. Conclusions: Large regenerative nodules with an FNH-like appearance on CEUS or MRI have not been previously reported in this setting. In our patient, Etanercept therapy produced a favourable hepatic response, reflected by a significant reduction in both the number and size of the lesions. Our case contributes to the understanding of liver disease in DADA2 and the influence of imaging and treatment on the hepatic manifestations of the condition.

The Natural History of Deficiency of Adenosine Deaminase 2 Vasculitis in a Large Cohort and Factors Associated With Disease-Related Damage.

The Journal of rheumatology2026 Feb 01

To describe the clinical and laboratory findings, disease course, and treatment effectiveness of a large, genetically homogenous group of patients with deficiency of adenosine deaminase 2 (DADA2), and to identify factors associated with disease-related damage. We conducted a retrospective cohort study that included 45 patients with DADA2 vasculitis with long-term follow-up. Information was collected from patients' charts, including demographic information, clinical presentations, laboratory findings, and treatment. The extent of disease-related damage was determined based on the Vasculitis Damage Index. In this large homogenous cohort, we found that a young age at disease onset and periodic illness that included recurrent episodes of fever, myalgia, and abdominal pain were associated with disease-related damage. Patients with severe DADA2 disease responded favorably to tumor necrosis factor inhibitors (TNFi). Early age of onset and the periodic nature of the disease warrant prompt initiation of TNFi treatment to prevent later complications and severe disease progression.
