Intrahepatic IgG/IgM plasma cells ratio helps in classifying autoimmune liver diseases.
2010
Abstract Background/Aim Plasma cells infiltrate in the liver is a prototype lesion of autoimmune liver diseases. The possible role of plasma cells isotyping (IgM and IgG) in the liver in the diagnostic definition of autoimmune liver disease, and particularly in variant syndromes such as autoimmune cholangitis and the primary biliary cirrhosis/autoimmune hepatitis overlap syndrome, is less defined. Methods We analysed the clinical, serological and histological features of 83 patients with autoimmune liver disease (40 primary biliary cirrhosis, 20 autoimmune hepatitis, 13 primary sclerosing cholangitis, 4 autoimmune cholangitis and 6 overlap syndrome) compared to 34 patients with chronic hepa…
Detection of IgM antibodies specific for measles virus by capture and indirect enzyme immunoassays.
1995
Summary During a measles outbreak, 112 serum specimens from 88 hospitalized patients were received in our laboratory for investigation of a morbilliform rash. These specimens (88 acute- and 24 convalescent-phase) were tested for the presence of measles-specific IgM antibodies by a capture EIA (enzyme immunoassay) using peroxidase-conjugated measles virus antigens and by an indirect EIA. Commercially available indirect EIA kits for measles-specific IgM antibodies were also used and compared with our homemade EIAs. Specificity studies included a collection of serum specimens containing rheumatoid factor, antinuclear antibodies or IgM antibodies specific to other viruses, and sera from blood d…

Raffittimento della rete IGM95 con l’uso di stazioni permanenti GNSS: il caso della provincia di Trapani
2008
La sperimentazione descritta in questo lavoro riguarda la prima parte di un progetto di ricerca, tuttora in corso, che vede coinvolti l’Istituto Geografico Militare e il Dipartimento di Rappresentazione dell’Università di Palermo (DIRAP), avente come tema il raffittimento della rete IGM95 in Sicilia con l’impiego delle Reti di Stazioni Permanenti GNNS. In particolare, sono illustrati i primi risultati di uno studio relativo alla progettazione della rete di raffittimento nella provincia di Trapani e alle prime verifiche sperimentali per valutare il grado di precisione ottenuto con rilievi statici e NTRK effettuati con l’impiego di alcuni punti di coordinate note.
Peculiar hyper-IgM syndrome. Case report / Sindrom hiper-IgM atipic. Prezentare de caz
2015
Abstract We report a male infant diagnosed at the age of 10 months with hyper-IgM syndrome (HIGM) in context of severe infections caused by Streptococcus pneumoniae, Staphylococcus aureus and Candida albicans. In patient’s outcome, in spite of immunoglobulin therapy, he continues presenting bilateral suppurative otitis media due to both Candida and penicillin-resistant pneumococcus and forearm abscess caused by Staphylococcus aureus. The infant developed bilateral cataracts, chronic hepatitis and comminuted fracture secondary to bone demineralization. The patient didn’t develop opportunistic infections as compare to CD40 Ligand deficiency patients. In contrast with the majority of HIGM case…
Genome-wide association study of motor coordination problems in ADHD identifies genes for brain and muscle function.
2012
Item does not contain fulltext OBJECTIVES: Motor coordination problems are frequent in children with attention deficit/hyperactivity disorder (ADHD). We performed a genome-wide association study to identify genes contributing to motor coordination problems, hypothesizing that the presence of such problems in children with ADHD may identify a sample of reduced genetic heterogeneity. METHODS: Children with ADHD from the International Multicentre ADHD Genetic (IMAGE) study were evaluated with the Parental Account of Children's Symptoms. Genetic association testing was performed in PLINK on 890 probands with genome-wide genotyping data. Bioinformatics enrichment-analysis was performed on highly…
Candidate genetic pathways for attention-deficit/hyperactivity disorder (ADHD) show association to hyperactive/impulsive symptoms in children with AD…
2013
Item does not contain fulltext OBJECTIVE: Because multiple genes with small effect sizes are assumed to play a role in attention-deficit/hyperactivity disorder (ADHD) etiology, considering multiple variants within the same analysis likely increases the total explained phenotypic variance, thereby boosting the power of genetic studies. This study investigated whether pathway-based analysis could bring scientists closer to unraveling the biology of ADHD. METHOD: The pathway was described as a predefined gene selection based on a well-established database or literature data. Common genetic variants in pathways involved in dopamine/norepinephrine and serotonin neurotransmission and genes involv…
Anti-16-kilodalton mycobacterial protein immunoglobulin M levels in healthy but purified protein derivative-reactive children decrease after chemopro…
2007
ABSTRACT Serum responses against Mycobacterium tuberculosis HSP16 were determined for children with tuberculosis (TB) and for healthy purified protein derivative (PPD)-positive and PPD-negative children. Immunoglobulin G (IgG) and IgM responses were higher for TB patients than for other groups. After chemotherapy, IgM and IgG responses decreased for TB patients and PPD-positive subjects. Monitoring of anti- M. tuberculosis HSP16 responses could assist in the management of pediatric TB.
Genetic relationship between five psychiatric disorders estimated from genome-wide SNPs
2013
AM Vicente - Cross-Disorder Group of the Psychiatric Genomics Consortium Most psychiatric disorders are moderately to highly heritable. The degree to which genetic variation is unique to individual disorders or shared across disorders is unclear. To examine shared genetic etiology, we use genome-wide genotype data from the Psychiatric Genomics Consortium (PGC) for cases and controls in schizophrenia, bipolar disorder, major depressive disorder, autism spectrum disorders (ASD) and attention-deficit/hyperactivity disorder (ADHD). We apply univariate and bivariate methods for the estimation of genetic variation within and covariation between disorders. SNPs explained 17-29% of the variance in …
Higher levels of IgA and IgG at sepsis onset are associated with higher mortality: results from the Albumin Italian Outcome Sepsis (ALBIOS) trial
2021
Abstract Background The role of intravenous immunoglobulins (IVIG) during sepsis is controversial, as different trials on IVIG have observed inconsistent survival benefits. We aimed to elucidate the possible association and clinical significance between circulating levels of immunoglobulins. Methods In a subset of 956 patients with severe sepsis and septic shock of the multicentre, open-label RCT ALBIOS, venous blood samples were serially collected 1, 2, and 7 days after enrolment (or at ICU discharge, whichever came first). IgA, IgG and IgM concentrations were assayed in all patients on day 1 and in a subgroup of 150 patients on days 2 and 7. Ig concentrations were measured employing a tur…
