Detection of serum anti-Leishmania antibodies by quantitative or qualitative techniques has been the most used method to diagnose Canine Leishmaniosis (CanL). Nevertheless, saliva may represent an alternative to blood because it is easy to collect, painless and non-invasive in comparison with serum. In this study, two time-resolved immunofluorometric assays (TR-IFMAs) for quantification of anti-Leishmania IgG2 and IgA antibodies in saliva were developed and validated and their ability to distinguish Leishmania-seronegative from seropositive dogs was evaluated...

OBJECTIVE: An increased risk of multiple myeloma (MM) has been observed among individuals with low prediagnostic circulating levels of adiponectin, a metabolic hormone that is typically underexpressed among those with overweight or obesity. To assess whether adiponectin may influence myeloma development or progression to frank MM, circulating adiponectin levels were compared across patients with different stages of MM and its precursor, monoclonal gammopathy of undetermined significance (MGUS)...

Characterization of Ag-specific BCR repertoires is essential for understanding disease mechanisms involving humoral immunity. This is optimally done by interrogation of paired H chain V region (VH) and L chain V region (VL) sequences of individual and Ag-specific B cells. By applying single-cell high-throughput sequencing on gut lesion plasma cells (PCs), we have analyzed the transglutaminase 2 (TG2)-specific VH:VL autoantibody repertoire of celiac disease (CD) patients. Autoantibodies against TG2 are a hallmark of CD, and anti-TG2 IgA-producing gut PCs accumulate in patients upon gluten ingestion...

OBJECTIVES: Rheumatoid arthritis (RA) patients show low serum levels of the Ag dipeptidyl peptidase IV (DPP-IV/CD26), both soluble CD26 (sCD26) concentration and its DPP-IV activity. The aim of this study was to test if anti-DPP-IV/CD26 Abs (Anti-CD26) cleared sCD26. DESIGN & METHODS: Serum Anti-CD26 and Total titers (as comparison) of isotypes IgA, IgM and IgG as well as sCD26 concentration and DPP-IV activity were measured in a cohort of RA patients undergoing different biological and non-biological therapies (n=105) and controls (n=50)...

A hypothesis for schizophrenia (SCZ) called the "microglia hypothesis" has been suggested. In SCZ, expression of triggering receptor expressed on myeloid cell 2 (TREM2) mRNA is higher in leukocytes than in healthy individuals. Here, the methylation rates of four CpG sites in TREM2 intron 1 that may bind important transcription factors and the correlation between the methylation rate and mRNA expression were determined. We compared the methylation rates in SCZ patients and age-matched controls (n = 50 each)...

This study aimed to confirm that atherosclerosis (AS) is a systemic immune-mediated chronic inflammatory disease and to investigate the anti-atherosclerotic effect of demethylzeylasteral by testing the immunocompetent cells and inflammatory mediators in the blood and atherosclerotic plaques of the rabbit model of AS. For this purpose, 60 male New Zealand white rabbits were given 150 g high-fat diet (1% cholesterol, 5% lard, and 15% egg yolk powder) daily for a total of 90 days. On day 61, the rabbits were randomly divided into the saline group (n=15), the rosuvastatin group (n=15), the low-dose demethylzeylasteral group (n=15), and the high-dose demethylzeylasteral group (n=15)...

In spite of there being a number of vaccines, influenza remains a significant global cause of morbidity and mortality. Understanding more about natural and vaccine induced immune protection against influenza infection would help to develop better vaccines. Virus specific IgG is a known correlate of protection, but other factors may help to reduce viral load or disease severity, for example IgA. In the current study we measured influenza specific responses in a controlled human infection model using influenza A/California/2009 (H1N1) as the challenge agent...

Asthma exacerbation is associated with respiratory infections, including those by viruses and atypical bacteria. We herein report a case of severe acute asthma in an adult caused by Chlamydophila pneumoniae (C. pneumoniae) infection. A 39-year-old woman without a history of asthma reported to the emergency department with progressive worsening of cough, shortness of breath, and wheezing with low oxygen saturation. A computed tomography (CT) scan revealed patchy ground-glass opacity and bronchial wall thickening...

A 57-year-old woman with frequent respiratory infections was initially diagnosed with IgG subclass deficiency based on low levels of IgG subclasses 2 and 3. Three years later, she progressed to having IgA deficiency as well. With a normal total IgG level, she does not meet criteria for common variable immunodeficiency (CVID). This may represent a variant of CVID. This also highlights the importance of immunoglobulin subclass estimation in patients where immunodeficiency is suspected clinically. She is being treated with rotational antibiotics the first 10 days of every month, monthly intravenous immunoglobulin (IVIG) infusion and osteopathic manipulation one to two times per month...

AIM: Oxidized Low-Density Lipoproteins (oxLDL) are formed as a result of lipid peroxidation and are highly immunogenic and proatherogenic. In this study, saliva antibodies binding to oxLDL, Porphyromonas gingivalis (Pg) and Aggregatibacter actinomycetemcomitans (Aa), were characterized and their cross reactivity was evaluated. MATERIAL & METHODS: Resting and stimulated saliva samples were collected from 36 healthy adults (mean age 26 years). Saliva IgA, IgG and IgM autoantibody levels to copper oxidized LDL (CuOx-LDL) and malondialdehyde acetaldehyde modified LDL (MAA-LDL), were determined with chemiluminescence immunoassay...

BACKGROUND: Permanent prostate brachytherapy (PPB) is an effective treatment choice for low and intermediate risk prostate cancer (PCa). However, the impact of PPB on tumor immune status is still poorly understood. This study aimed to assess the immune status in PCa patients before and at different time points after PPB (1, 3, 6, and 12 months). METHODS: Blood was collected from 32 patients with low and intermediate risk PCa and 12 healthy volunteers. The frequency of immunocompetent cells was identified by flow cytometry...

BACKGROUND & AIMS: Tests to measure serum endomysial antibodies (EMA) and antibodies to tissue transglutaminase (tTG) were developed to screen for celiac disease in patients consuming gluten. However, they are commonly used to monitor patients on a gluten-free diet (GFD). We conducted a meta-analysis to assess the sensitivity and specificity of tTG IgA and EMA IgA assays in identifying patients with celiac disease who have persistent villous atrophy despite a GFD. METHODS: We searched PUBMED, EMBASE, BIOSIS, SCOPUS, clinicaltrials...

BACKGROUND: The diagnosis of myeloma, a plasma dyscrasia, often results from the workup of unexplained renal disease. Persistent renal failure in myeloma is commonly caused by tubular nephropathy due to circulating immunoglobulins and free light chains. Myeloma cast nephropathy is characterized by crystalline precipitates of monoclonal light chains within distal tubules. Immunoglobulin crystallization rarely occurs intracellularly, within proximal tubular cells (light chain proximal tubulopathy) and interstitial histiocytes (crystal-storing histiocytosis)...

A genogroup 2b (G2b) porcine epidemic diarrhea virus (PEDV) Taiwan Pintung 52 (PEDVPT) strain was isolated in 2014. The pathogenicity and host antibody responses elicited by low-passage (passage 5; PEDVPT-P5) and high-passage (passage 96; PEDVPT-P96) PEDVPT strains were compared in post-weaning PEDV-seronegative pigs by oral inoculation. PEDVPT-P5-inoculation induced typical diarrhea during 1-9 days post inoculation with fecal viral shedding persisting for 26 days. Compared to PEDVPT-P5, PEDVPT-P96 inoculation induced none-to-mild diarrhea and lower, delayed fecal viral shedding...

INTRODUCTION: Both reactive arthritis (ReA) and undifferentiated spondyloarthritis (uSpA) belong to the group of autoinflammatory diseases called spondyloarthritis (SpA). Hypotheses have been proposed about a relationship between the intestinal mucosa and inflammation of joint tissues. The role of immunoglobulin IgA or secretory immunoglobulin A (SIgA) in the inflammatory and/or clinical activity of patients with SpA remains poorly understood. OBJECTIVE: To evaluate the status of total IgA and SIgA, and the association among the levels of SIgA, IgA, IgA anti-Chlamydia trachomatis, and anti-Shigella spp...

BACKGROUND: Efficacy of live oral rotavirus vaccines is reduced in low-income compared with high-income settings. Parenteral non-replicating rotavirus vaccines might offer benefits over oral vaccines. We assessed the safety and immunogenicity of the P2-VP8-P[8] subunit rotavirus vaccine at different doses in South African toddlers and infants. METHODS: This double-blind, randomised, placebo-controlled, dose-escalation trial was done at a single research unit based at a hospital in South Africa in healthy HIV-uninfected toddlers (aged 2 to <3 years) and term infants (aged 6 to <8 weeks, without previous rotavirus vaccination)...
