Hematuria is one of the basic clinical manifestations of IgA nephropathy (IgAN). Isolated microscopic hematuria or microscopic hematuria combined with proteinuria is risk factor for the long-term prognosis of IgAN. Current evidence of the consequences of glomerular hematuria rests on insights from basic research on the molecular mechanisms of hemoglobin and related reactive oxygen species-induced tubular injury as well as on the clinical evidence of macroscopic hematuria-associated acute kidney injury (AKI) in IgAN...

Domain I (DI) of beta-2-glycoprotein I (β2GPI) contains the immunodominant epitope for pathogenic antiphospholipid antibodies (aPL). DI is exposed in the linear form of the molecule but not in the circular form that comprises 90% of serum β2GPI. The majority of circulating β2GPI is biochemically reduced with two free thiols in Domain V. However, increased levels of oxidised β2GPI are found in patients with antiphospholipid syndrome (APS). It is not known whether oxidation of β2GPI favours the linear form of the molecule and thus promotes development of anti-DI antibodies...

A major role of the corpus luteum (CL) is to produce progesterone (P4). The CL has immature vasculature shortly after ovulation, suggesting it exists under hypoxic conditions. Hypoxia-inducible factor-1 (HIF1) induces the expression of glucose transporter 1 (GLUT1). To clarify the physiological roles of GLUT1 in bovine CL, we examined GLUT1 mRNA expression in the CL under hypoxic conditions by quantitative RT-PCR. We also measured the effects of glucose (0-25 mM) and GLUT1 inhibitors (cytochalasin B, STF-31) on P4 production in bovine luteal cells...

The importance of pertussis toxin (PT) IgA testing in the diagnosis of recent pertussis infection remains unclear. The contribution of PT IgA to the diagnosis of recent pertussis was reviewed in two separate analyses. Firstly, an evaluation of two new automated assays [DiaSorin Liaison (DL), Italy] for PT IgG and PT IgA provided an opportunity to assess the contribution of PT IgA testing to PT IgG results. Secondly, a retrospective review of results from the PT IgA assay currently in use [Sullivan Nicolaides Pathology (SNP) PT IgA] was performed from 2013 to 2015 (n=63,474)...

OBJECTIVE: To investigate the immunological mechanism of prednisone in the treatment of infantile spasm (IS) by evaluating the immune function of IS children before and after treatment. METHODS: Thirty children with IS were enrolled as IS group. Thirty healthy infants who underwent physical examination were enrolled as healthy control group. Fasting venous blood was collected for both groups before and after prednisone treatment. Chemiluminescence was used to measure serum levels of interleukin-1B (IL-1B), interleukin-2R (IL-2R), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α)...

Heparin-induced thrombocytopenia (HIT) is one of the serious complications in patients who undergo cardiac surgery. However, there remains a major problem in diagnosing HIT because the current immunological assays for detection of HIT antibody have limitations. Furthermore, the clinical course of thrombocytopenia in this surgery makes it increasingly difficult to diagnose HIT. We investigated the relationship between platelet count and HIT antibody in 59 patients who underwent cardiac surgery using cardiopulmonary bypass (CPB)...

In recent decades, diseases caused by pathogenic Escherichia coli (E. coli), enterohaemorrhagic E. coli (EHEC) O26 have been increasingly reported worldwide, which are as severe as those caused by EHEC strain O157:H7 and require effective intervention strategies. Herein, we report the application of clay nanoparticles, i.e. hectorites as effective nano-adjuvants for vaccination against EHEC O26 colonization. We show that medium size HEC (hectorite, around 73~77 nm diameter) is able to induce efficient humoral and cellular immune responses against EHEC antigen - intimin β (IB), which are significantly higher than those triggered by commercially used adjuvants - QuilA and Alum...

BACKGROUND: In 2010, INF2 mutations were associated with autosomal-dominant focal segmental glomerulosclerosis (FSGS), clinically presenting with moderate proteinuria in adolescence. However, in the meantime, cases with more severe clinical courses have been described, including progression to end-stage renal disease (ESRD) during childhood. INF2 mutations in patients with isolated FSGS are clustered in exons 2 to 4, encoding the diaphanous inhibitory domain, involved in the regulation of the podocyte actin cytoskeleton...

Immunoglobulin A vasculitis (IgAV), also referred to as Henoch-Schönlein purpura, is the most common form of childhood vasculitis. The pathogenesis of IgAV is still largely unknown. The disease is characterized by IgA1-immune deposits, complement factors and neutrophil infiltration, which is accompanied with vascular inflammation. Incidence of IgAV is twice as high during fall and winter, suggesting an environmental trigger associated to climate. Symptoms can resolve without intervention, but some patients develop glomerulonephritis with features similar to IgA nephropathy that include hematuria, proteinuria and IgA deposition in the glomerulus...

Purpose of review Several advances have been made on the pathogenesis and therapy of neuropathies associated with paraproteinemia (monoclonal gammopathy). It is important for the neurologist to understand the pathogenetic relevance of this association especially when the hematological disease does not require per se any therapy. Recent findings Treatment of the neuropathy in patients with malignant paraproteinemia is mainly addressed by the hematologist while the neurologist is mainly involved in the initial diagnosis and in deciding whether the neuropathy is caused by the disease or by the chemotherapy used for the disease...

BACKGROUND: The bronchial mucosa is protected by a specialized immune system focused on the prevention of colonization and infection by potentially pathogenic microorganisms (PPMs). Immunoglobulin A (IgA) is the principal antibody involved in this mechanism. A defective immune barrier may facilitate the recurrent presence of PPMs in COPD. PURPOSE: The aim of this study was to determine IgA-mediated bronchial specific immune responses against Pseudomonas aeruginosa in stable patients with severe disease...

IgA vasculitis (IgAV) commonly occurs in young children, who present with a tetrad of purpura, abdominal pain, arthralgia and nephritis. Diffuse alveolar hemorrhage (DAH) is a rare complication of IgAV. We herein report an adult case of IgAV with a presentation of DAH and nephritis (pulmonary renal syndrome, PRS), but without other typical manifestations, such as purpura, abdominal pain and arthralgia. A 33-year-old man presented with hemoptysis and a low-grade fever and was diagnosed to have IgAV based on the results of a renal biopsy...

Secretory Immunoglobulin A (sIgA) plays a critical role to infant gut mucosal immunity. Delayed IgA production is associated with greater risk of allergic disease. Murine models of stressful events during pregnancy and infancy show alterations in gut immunity and microbial composition in offspring, but little is known about the stress-microbiome-immunity pathways in humans. We investigated differences in infant fecal sIgA concentrations according to the presence of maternal depressive symptoms during and after pregnancy...
