The PROSIT Cohort of Infliximab Biosimilar in IBD: A Prolonged Follow-up on the Effectiveness and Safety Across Italy.

Background: We report a prospective, nationwide cohort evaluating the safety and effectiveness of CT-P13.

Methods: A structured database was used to record serious adverse events (SAEs), clinical remission/response, inflammatory biomarkers (CRP and calprotectin), and endoscopic findings.

Results: Eight hundred ten patients with inflammatory bowel disease (IBD) (452 Crohn's disease [CD]) were enrolled.

Acute cerebellitis in children: an eleven year retrospective multicentric study in Italy.

Background: Acute cerebellitis (AC) and acute cerebellar ataxia (ACA) are the principal causes of acute cerebellar dysfunction in childhood. Nevertheless. there is no accepted consensus regarding the best management of children with AC/ACA: the aim of the study is both to assess clinical, neuroimaging and electrophysiologic features of children with AC/ACA and to evaluate the correlation between clinical parameters, therapy and outcome.

Epigenetically induced ectopic expression of UNCX impairs the proliferation and differentiation of myeloid cells.

We here describe a leukemogenic role of the homeobox gene , activated by epigenetic modifications in acute myeloid leukemia (AML). We found the ectopic activation of in a leukemia patient harboring a t(7;10)(p22;p14) translocation, in 22 of 61 of additional cases [a total of 23 positive patients out of 62 (37.1%)], and in 6 of 75 (8%) of AML cell lines.

The PROSIT-BIO Cohort: A Prospective Observational Study of Patients with Inflammatory Bowel Disease Treated with Infliximab Biosimilar.

Background: Few data are available on the safety and efficacy of infliximab biosimilar CT-P13 in patients with ulcerative colitis and Crohn's disease.

Methods: A prospective, multicenter, cohort study using a structured database.

Results: Consecutive patients (313 Crohn's disease and 234 ulcerative colitis) were enrolled from 31 referral centers; 311 patients were naive to anti-tumor necrosis factor alpha, 139 had a previous exposure to biologics, and the remaining 97 were switched to CT-P13 after a mean of 18 ± 14 infusions of infliximab.

A protein-truncating R179X variant in RNF186 confers protection against ulcerative colitis.

Protein-truncating variants protective against human disease provide in vivo validation of therapeutic targets. Here we used targeted sequencing to conduct a search for protein-truncating variants conferring protection against inflammatory bowel disease exploiting knowledge of common variants associated with the same disease. Through replication genotyping and imputation we found that a predicted protein-truncating variant (rs36095412, p.

Inherited determinants of Crohn's disease and ulcerative colitis phenotypes: a genetic association study.

Background: Crohn's disease and ulcerative colitis are the two major forms of inflammatory bowel disease; treatment strategies have historically been determined by this binary categorisation. Genetic studies have identified 163 susceptibility loci for inflammatory bowel disease, mostly shared between Crohn's disease and ulcerative colitis. We undertook the largest genotype association study, to date, in widely used clinical subphenotypes of inflammatory bowel disease with the goal of further understanding the biological relations between diseases.

Impact of CR before and after allogeneic and autologous transplantation in multiple myeloma: results from the EBMT NMAM2000 prospective trial.

Previous studies have shown that obtaining complete hematologic remission (CR) in multiple myeloma is an important predictor of PFS and OS. This applies both to autologous and allogeneic transplantation. However, the importance of CR obtained before vs after second transplant or following allogeneic vs autologous transplantation is not clear.

Use of biosimilars in inflammatory bowel disease: Statements of the Italian Group for Inflammatory Bowel Disease.

The introduction of biological therapies, particularly anti-TNFα agents, has revolutionized the management of inflammatory bowel disease in those cases which are refractory to conventional treatment; however these drugs are not risk-free and their use has substantially increased the cost of treatment. As marketing protection expires for original, first-generation biopharmaceuticals, lower-cost "copies" of these drugs produced by competitor companies-referred to as biosimilars-are already entering the market. In September 2013, the European Medicines Agency approved two infliximab biosimilars for treatment of adult and paediatric inflammatory bowel disease patients, a decision based largely on efficacy and safety data generated in studies of patients with ankylosing spondylitis and rheumatoid arthritis.

Evaluation of genome-wide expression profiles of blood and sputum neutrophils in cystic fibrosis patients before and after antibiotic therapy.

In seeking more specific biomarkers of the cystic fibrosis (CF) lung inflammatory disease that would be sensitive to antibiotic therapy, we sought to evaluate the gene expression profiles of neutrophils in CF patients before treatment in comparison with non-CF healthy individuals and after antibiotic treatment. Genes involved in neutrophil-mediated inflammation, i.e.

Heterotopic pancreas in gall bladder associated with chronic cholecystolithiasis.

Heterotopic pancreatic tissue in the gallbladder is a very uncommon lesion, which is an incidental finding in most cases. We report here, a case of an 18-year-old, post puerperal female, suffering from right upper quadrant abdominal pain with a clinical diagnosis of chronic cholecystitis, in whom heterotopic pancreatic tissue was found in the gall bladder.

High-resolution SNP arrays in mental retardation diagnostics: how much do we gain?

We used Affymetrix 6.0 GeneChip SNP arrays to characterize copy number variations (CNVs) in a cohort of 70 patients previously characterized on lower-density oligonucleotide arrays affected by idiopathic mental retardation and dysmorphic features. The SNP array platform includes approximately 900,000 SNP probes and 900,000 non-SNP oligonucleotide probes at an average distance of 0.

Comparison between real-time quantitative PCR detection of HER2 mRNA copy number in peripheral blood and ELISA of serum HER2 protein for determining HER2 status in breast cancer patients.

Background: The development of non-invasive procedure to determine HER2 status may represent a powerful method for monitoring disease progression and response to the treatment.

Methods: Serum samples and RNA from peripheral blood were evaluated in 85 breast cancer patients (49 HER2 positive and 36 HER2 negative) and 22 healthy controls. HER2 mRNA levels were measured by real-time quantitative PCR (QPCR) and serum HER2 protein by immunoenzimatic assay (EIA).

Complex rearrangement of chromosomes 7q21.13-q22.1 confirms the ectrodactyly-deafness locus and suggests new candidate genes.

Complex chromosomal rearrangements with more than two breakpoints are rare. We report on a 5-year-old girl, evaluated because of psychomotor delay, ectrodactyly of right hand and feet, craniofacial dysmorphic features, cleft palate, deafness, and tetralogy of Fallot. A standard karyotype suggested a small intrachromosomal duplication of chromosome 7q.

Syndromic craniosynostosis due to complex chromosome 5 rearrangement and MSX2 gene triplication.

Craniosynostosis is a common birth defect ( approximately 1/3,000 births) resulting from chromosome imbalances, gene mutations or unknown causes. We report a 6-month-old female with multiple sutural synostosis and prenatal onset growth deficiency, developmental delay, facial dysmorphism, congenital heart defect, and inguinal hernia. An integrated approach of standard cytogenetics, mBAND, locus-specific FISH, and 75 kb resolution array-CGH disclosed a complex chromosome 5 rearrangement, resulting in 3 paracentric inversions, 2 between-arm insertions, and partial duplication of 5q35.

Development of real-time quantitative reverse transcription-PCR for Her2 detection in peripheral blood from patients with breast cancer.

Background: Amplification of the Her2neu oncogene is a well known indicator of poor prognosis in breast cancer patients. The implementation into the clinical setting of therapeutical strategies directly targeting the Her2neu gene product, has create the need for the development of non-invasive analytical techniques in order to monitoring minimal residual disease and response to the treatment.

Methods: To detect the expression of Her2neu mRNA in peripheral blood, we developed a specific real-time quantitative reverse transcription-PCR (QPCR) assay.

KBG syndrome.

KBG syndrome is a rare condition characterised by a typical facial dysmorphism, macrodontia of the upper central incisors, skeletal (mainly costovertebral) anomalies and developmental delay. To date, KBG syndrome has been reported in 45 patients. Clinical features observed in more than half of patients that may support the diagnosis are short stature, electroencephalogram (EEG) anomalies (with or without seizures) and abnormal hair implantation.

Pegylated interferon alpha-2b as monotherapy or in combination with ribavirin in chronic hepatitis delta.

Therapy of chronic hepatitis delta with standard interferon therapy has met with limited efficacy. This study was designed to examine the efficacy and safety of peginterferon with or without ribavirin. Thirty-eight serum hepatitis B surface antigen- and HDV RNA-positive patients with alanine aminotransferase (ALT) more than 1.

Combined test for UGT1A1 -3279T-->G and A(TA)nTAA polymorphisms best predicts Gilbert's syndrome in Italian pediatric patients.

Gilbert's syndrome is a common hereditary chronic or recurrent, mild unconjugated hyperbilirubinemia. Polymorphisms in the bilirubin uridine diphosphate glucuronosyl transferase gene (UGT1A1) causing a decreased enzyme activity are associated with susceptibility to the syndrome. Homozygosity for TA(7) allele of the A(TA)(n)TAA promoter polymorphism is found in the majority of Caucasian patients.

Relationship between CARD15, SLC22A4/5, and DLG5 polymorphisms and early-onset inflammatory bowel diseases: an Italian multicentric study.

Background: Inflammatory bowel disease (IBD) has been associated with several polymorphisms in genes likely involved in innate immune responses and integrity of epithelial mucosal barrier. A major role in adult Crohn's disease (CD) has been defined for 3 polymorphisms in the CARD15 gene, whereas variants in the SLC22A4, SLC22A5, and DLG5 genes could have a minor contribution to IBD susceptibility.

Methods: We analyzed a panel of 6 polymorphisms within these genes in 227 Italian early-onset IBD patients (134 CD, 93 ulcerative colitis [UC]; age at diagnosis View Article and Find Full Text PDF

Shprintzen-Goldberg omphalocele syndrome: a new patient with an expanded phenotype.

Shprintzen and Goldberg [1979] described a new autosomal dominant syndrome characterized by omphalocele, scoliosis, pharyngeal and laryngeal hypoplasia, mild dysmorphic face, and learning disabilities. This condition was described in a father and three daughters, one of whom died in infancy, probably of airway narrowing. Here, we report on a second observation of this syndrome in a 6-year-old patient.

NF1 gene mutations represent the major molecular event underlying neurofibromatosis-Noonan syndrome.

Neurofibromatosis type 1 (NF1) demonstrates phenotypic overlap with Noonan syndrome (NS) in some patients, which results in the so-called neurofibromatosis-Noonan syndrome (NFNS). From a genetic point of view, NFNS is a poorly understood condition, and controversy remains as to whether it represents a variable manifestation of either NF1 or NS or is a distinct clinical entity. To answer this question, we screened a cohort with clinically well-characterized NFNS for mutations in the entire coding sequence of the NF1 and PTPN11 genes.
