Ocular and oral dryness are the hallmark of Sjögren's syndrome (SS). However, SS can be associated with a variety of complications, affecting organs such as the liver, kidneys, lungs, muscle, and nervous system. Renal involvement has been usually in the form of tubulointerstitial nephritis. However, glomerulonephritis is rare in primary SS. We report three clinical cases of SS with anti-neutrophil cytoplasmic antibody-mediated crescentic glomerulo-nephritis treated with prednisone and cyclophosphamide, with favorable outcome...

Extracellular adenosine, generated via the concerted action of CD39 and CD73, contributes to T-cell differentiation and function. Adenosine concentrations are furthermore influenced by adenosine deaminase binding protein CD26. Because aberrant T-cell phenotypes had been reported in anti-neutrophil cytoplasmic auto-antibody (ANCA)-associated vasculitis (AAV) patients, an impaired expression of these molecules on T-cells of AAV patients was hypothesized in the present study. While in AAV patients (n = 29) CD26 was increased on CD4(+) lymphocytes, CD39 and CD73 were generally reduced on patients' T-cells...

Anti-neutrophil cytoplasmic antibodies (ANCAs) are valuable laboratory markers used for the diagnosis of well-defined types of small-vessel vasculitis, including granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). According to the 1999 international consensus on ANCA testing, indirect immunofluorescence (IIF) should be used to screen for ANCAs, and samples containing ANCAs should then be tested by immunoassays for proteinase 3 (PR3)-ANCAs and myeloperoxidase (MPO)-ANCAs. The distinction between PR3-ANCAs and MPO-ANCAs has important clinical and pathogenic implications...

The structures named neutrophil extracellular traps (NETs) are fibrous networks which protrude from the membrane of activated neutrophils. NETs are found in a variety of conditions, such as infection, malignancy, atherosclerosis, and autoimmune diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV), psoriasis, and gout. The impact of NETs on the development mechanisms of autoimmune diseases are proposed to arise from an imbalance between "NETosis" which is a process of NET formation and NET degradation...

OBJECTIVE: Neutrophil extracellular traps (NETs) are peculiar structures composed of the externalized chromatin with intracellular proteins and formed by activated neutrophils in a reactive oxygen species (ROS)-dependent manner. Aberrant NETs are considered to be autoantigens for anti-neutrophil cytoplasmic antibodies (ANCAs) underling the development of microscopic polyangiitis (MPA). However, little is known regarding the therapeutic efficacy of in vivo inhibition of NET formation (NETosis) on MPA pathogenesis...

Mast cells are important cells of the immune system. Although traditionally considered as key players in allergic and hypersensitivity reactions, emerging evidence suggests that mast cells have many complex roles in vascular disease. These include regulation of vasodilation, angiogenesis, activation of matrix metalloproteinases, apoptosis of smooth muscle cells, and activation of the renin angiotensin system. Mast cells are also known to play an immunomodulatory role via modulation of regulatory T-cell (Treg), macrophage and endothelial cell functions...

BACKGROUND: Three recent studies from the United States and China reported the clinicopathological features and short-term prognosis in patients with membranous nephropathy (MN) and crescents in the absence of secondary MN, anti-glomerular basement membrane (GBM) antibodies, and anti-neutrophil cytoplasmic antibodies (ANCA). METHODS: We compared clinicopathological and prognostic features in 16 MN patients with crescents (crescent group) and 38 MN patients without crescents (control group), in the absence of secondary MN, anti-GBM antibodies, and ANCA...

BACKGROUND: Rituximab (RTX), a B cell-depleting anti-CD20 monoclonal antibody, is approved for treatment of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Low immunoglobulin (Ig) levels have been observed surrounding RTX treatment. The association between the degree of Ig deficiency and infection risk is unclear in AAV patients. METHODS: AAV patients treated with RTX for remission induction at a single center (2005-15) with serum Ig measurements were included...

BACKGROUND: Kidney biopsy is a gold standard for diagnosis of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), but it is unknown whether vasculitis can be detected from AAV patients with minor urinary abnormalities. METHODS: Ninety ANCA-positive patients undergoing kidney biopsy were evaluated retrospectively after being divided into two groups, which were group A (minor urinary abnormalities with both proteinuria <0.5 g/day and red blood cells ≤5 /high power field) and group B (major urinary abnormalities except group A)...

The present study was planned to evaluate correlation between Helicobacter pylori (HP) infection and autoimmune liver disease (AILD). A total of 60 patients diagnosed with AILD in Affiliated Hospital of Binzhou Medical College were continuously enrolled in the present study. HP infection was detected by 13C-urea breath test. The levels of anti-myeloperoxidase were tested by ELISA. The positive rate of anti-nuclear antibody (ANA), anti-mitochondrial antibody (AMA), anti-smooth muscle antibody (SMA) and anti-neutrophil cytoplasm antibody (ANCA) were tested by indirect immunofluorescence...

CD177 is a GPI-anchored protein expressed by a variable proportion of human neutrophils that mediates surface expression of the anti-neutrophil cytoplasmic antibody (ANCA) antigen proteinase 3. CD177 associates with β2 integrins and recognizes PECAM-1, suggesting a role in neutrophil migration. However, CD177(pos) neutrophils exhibit no clear migratory advantage in vivo, despite interruption of transendothelial migration by in vitro CD177 ligation. We sought to understand this paradox. Using a PECAM-1-independent transwell system, we found that CD177(pos) and CD177(neg) neutrophils migrated comparably...

CD4(+) T cells are important drivers of tissue damage in immune-mediated renal diseases, such as anti-glomerular basement membrane glomerulonephritis, anti-neutrophil cytoplasmic antibody-associated glomerulonephritis, and lupus nephritis. The discovery of a distinct, IL-17-producing CD4(+) T-cell lineage termed T helper type 17 (TH17) cells has markedly advanced current understanding of the pathogenic mechanisms of organ-specific immunity and the pathways that lead to target organ damage. TH17 cells are characterized by the expression of the transcription factor RORγt, the production of the pro-inflammatory cytokines IL-17A, IL-17F, IL-22, and high expression of the chemokine receptor C-C-motif chemokine receptor 6 (CCR6)...

OBJECTIVES: Patients with granulomatosis with polyangiitis (GPA) are prone to disease relapse. Currently, no good biomarkers are available to predict relapses in individual patients. This study aimed to determine whether patients at risk for relapse can be distinguished based on increased in vitro autoantibody production. METHODS: Eighty-four proteinase 3 (PR3) anti-neutrophil cytoplasmic antibody (ANCA) positive GPA outpatients were prospectively monitored for up to two years and 32 healthy controls were included...

IgG4-related disease is an immune-mediated fibro-inflammatory condition that affects multiple organ systems. When the pachymeninges are involved, it is termed IgG4-related hypertrophic pachymeningitis (IgG4-RHP). We present a 79-year-old woman with back pain found to have IgG4-RHP localized exclusively in the spine who was also seropositive for myeloperoxidase anti-neutrophil cytoplasmic antibodies (MPO-ANCA). This case is the first known report of IgG4-RHP in the spine with MPO-ANCA and adds to emerging evidence for potential disease overlap in the pathogenesis of hypertrophic pachymenigitis (HP)...

AIM: We investigated whether clinical manifestations, anti-neutrophil cytoplasmic antibodies (ANCAs), Birmingham vasculitis activity score (BVAS) for granulomatosis with polyangiitis (GPA) and five factor score (FFS) at diagnosis can predict relapse or refractory disease in 30 histology-proven GPA patients with follow-up duration ≥ 12 weeks. METHODS: We reviewed the medical records of 30 GPA patients. We collected clinical data, ANCAs, BVAS for GPA, FFSs at diagnosis, and we compared variables between the two groups based on relapse or refractory disease...
