OBJECTIVES: Blau syndrome (BS), a rare auto-inflammatory granulomatous disease, is a progressive disorder. Usually the maintenance dose of glucocorticoid may not be tapered below 15 mg per day while immunosuppressives is used. There has been some experience with biologic agents in refractory BS patients. The objective of this study is to describe the case of a BS patient benefiting from Tocilizumab, a humanized monoclonal antibody against interleukin 6 receptor. METHODS: We report the first Chinese patient with BS who was resistant to currently available therapies but had rapid quiescence after using Tocilizumab...

Mutations in the nucleotide binding domain of the PRR, NOD2, are associated with the autoinflammatory diseases Blau syndrome and early-onset sarcoidosis. Current theories suggest that constitutive activation of the NOD2 pathway may be responsible for pathogenesis of these diseases. Here, we report the phenotype of a kindred with Blau syndrome caused by a novel NOD2 mutation (p.E383D). Signaling protein and cytokine expression were examined, and the results of these experiments challenge current theories of constitutive NOD2 activation in the pathophysiology of Blau syndrome...

BACKGROUND: Pediatric autoinflammatory diseases are rare and still poorly understood conditions resulting from defective genetic control of innate immune system, inter alia from anomalies of NOD2 gene. The product of this gene is Nod2 protein, taking part in maintenance of immune homeostasis. Clinical form of resultant autoinflammatory condition depends on NOD2 genotype; usually patients with NOD2 defects present with Blau syndrome, NOD2-associated autoinflammatory disease (NAID) or Crohn's disease...

Blau syndrome (BS) is a rare autosomal dominant autoinflammatory disease characterized by the clinical triad of dermatitis, arthritis, and uveitis. It is caused by mutations in nucleotide-binding oligomerization domain-containing protein-2 (NOD2) gene. BS has been widely reported in Caucasians but cases documented in China are scarce. We reported two Chinese families with BS, which were by far the two largest pedigrees in the Chinese population. We identified two unrelated families with BS. The phenotypes and genotypes of these patients were reviewed and compared with previous cohorts...

The mutations of CARD15 gene and clinical features of Chinese patients with Blau syndrome were analyzed. We identified 10 missense mutations, out of which five were new: R334L, E383D, R471C, C495R and D512F. The rest of them, R334W, R334Q, G481D, M513T and R587C, have been reported previously. Among all the mutations, R334W, R334Q and C495R had the highest frequency. Blau syndrome was found at early age after birth. It began with lepidic rash and symmetric polyarthritis and was phenotypically characterized by typical rash, arthritis, iridocyclitis and arteritis...

BACKGROUND: Blau syndrome, or early-onset sarcoidosis, is a juvenile-onset systemic granulomatosis associated with a mutation in nucleotide-binding oligomerization domain 2 (NOD2). The underlying mechanisms of Blau syndrome leading to autoinflammation are still unclear, and there is currently no effective specific treatment for Blau syndrome. OBJECTIVES: To elucidate the mechanisms of autoinflammation in patients with Blau syndrome, we sought to clarify the relation between disease-associated mutant NOD2 and the inflammatory response in human samples...

Blau syndrome is an early-onset granulomatous disease known to affect the skin, joints, and eyes. We report a child with diffuse rash, arthritis, and subconjunctival nodules. Biopsy of the bulbar conjunctiva revealed noncaseating lipogranulomas that lead to a diagnosis of Blau syndrome. To our knowledge, noncaseating lipogranulomas of the conjunctiva have not been reported previously as a presenting finding in Blau syndrome. Although uveitis is the classic manifestation, it is important to broaden the awareness of other ocular signs, as these variations can aid in diagnosis...

Nucleotide-binding oligomerization domain 2 (NOD2) is an intracellular pattern recognition receptor that senses bacterial peptidoglycan (PGN)-conserved motifs in cytosol and stimulates host immune response. The association of NOD2 mutations with a number of inflammatory pathologies, including Crohn disease (CD), Graft-versus-host disease (GVHD), and Blau syndrome, highlights its pivotal role in host-pathogen interactions and inflammatory response. Stimulation of NOD2 by its ligand (muramyl dipeptide) activates pro-inflammatory pathways such as nuclear factor-κB (NF-κB), mitogen-activated protein kinases (MAPKs), and Caspase-1...

In April 2014, a kidney transplant recipient in the United States experienced headache, diplopia, and confusion, followed by neurologic decline and death. An investigation to evaluate the possibility of donor-derived infection determined that 3 patients had received 4 organs (kidney, liver, heart/kidney) from the same donor. The liver recipient experienced tremor and gait instability; the heart/kidney and contralateral kidney recipients were hospitalized with encephalitis. None experienced gastrointestinal symptoms...

Auto-inflammatory syndromes are a new group of distinct hereditable disorders characterized by episodes of seemingly unprovoked inflammation (most commonly in skin, joints, gut, and eye), the absence of a high titer of auto-antibodies or auto-reactive T cells, and an inborn error of innate immunity. A narrative literature review was carried out of studies related to auto-inflammatory syndromes to discuss the pathogenesis and clinical manifestation of these syndromes. This review showed that the main monogenic auto-inflammatory syndromes are familial Mediterranean fever (FMF), mevalonate kinase deficiency (MKD), Blau syndrome, TNF receptor-associated periodic syndrome (TRAPS), cryopyrin-associated periodic syndrome (CAPS), and pyogenic arthritis with pyoderma gangrenosum and acne (PAPA)...

Granulomas of the skin may be classified in several ways. They are either infectious or non-infectious in character, and they contain areas of necrobiosis or necrosis, or not. Responsible infectious agents may be mycobacterial, fungal, treponemal, or parasitic organisms, and each case of granulomatous dermatitis should be assessed histochemically for those microbes. In the non-infectious group, examples of necrobiotic or necrotizing granulomas include granuloma annulare; necrobiosis lipoidica; rheumatoid nodule; and lupus miliaris disseminates faciei...

Interleukin (IL)-1 plays a key role in the pathogenesis and thereafter in the search for specific treatments of different inflammatory and degenerative eye diseases. Indeed, an overactivity of IL-1 might be an initiating factor for many immunopathologic sceneries in the eye, as proven by the efficacy of the specific IL-1 blockade in different ocular diseases. For instance, the uveitis in monogenic autoinflammatory disorders, such as Blau syndrome and cryopyrin-associated periodic syndrome, or in complex polygenic autoinflammatory disorders, such as Behçet's disease, has been successfully treated with IL-1 blockers...

Blau syndrome (BS) is a rare autosomal dominant, inflammatory syndrome that is characterized by the clinical triad of granulomatous dermatitis, symmetric arthritis, and recurrent uveitis. Mutations in the nucleotide oligomerization domain 2 (NOD2) gene are responsible for causing BS. To date, up to 30 Blau-associated genetic mutations have been identified within this gene. We report a novel NOD2 genetic mutation that causes BS. A girl, aged 8 years, and her brother, aged 10 years, developed erythematous skin rashes and uveitis...

Nucleotide binding oligomerization domain 2 (NOD2), a protein involved in the first line defence mechanism has a pivotal role in innate immunity. Impaired function of this protein is implicated in disorders such as Blau syndrome and Crohn's disease. Since an altered function is linked to protein's structure, we framed a systematic strategy to interpret the structure-function relationship of the protein. Initiated with mutation-based pattern prediction and identified a distant ortholog (DO) of NOD2 from which the intra-residue interaction network was elucidated...

PURPOSE OF REVIEW: This article addresses the prevalence and relationship between autoinflammatory diseases and vasculitis. RECENT FINDINGS: Autoimmune diseases (AIDs) are a group of syndromes characterized by episodes of unprovoked inflammation due to dysregulation of the innate immune system. Despite the common occurrence of rashes and other skin lesions in these diseases, vasculitis is reported in only a few. On the other hand, neutrophilic dermatoses are more prevalent...
