Multiple Sclerosis: From the Application of Oligoclonal Bands to Novel Potential Biomarkers.

Multiple sclerosis is a chronic immune-mediated disorder of the central nervous system with a high heterogeneity among patients. In the clinical setting, one of the main challenges is a proper and early diagnosis for the prediction of disease activity. Current diagnosis is based on the integration of clinical, imaging, and laboratory results, with the latter based on the presence of intrathecal IgG oligoclonal bands in the cerebrospinal fluid whose detection via isoelectric focusing followed by immunoblotting represents the gold standard.

Biological, genetic and epigenetic markers in ulcerative colitis.

In this review, we have summarized the existing knowledge of ulcerative colitis (UC) markers based on current literature, specifically, the roles of potential new biomarkers, such as circulating, fecal, genetic, and epigenetic alterations, in UC onset, disease activity, and in therapy response. UC is a complex multifactorial inflammatory disease. There are many invasive and non-invasive diagnostic methods in UC, including several laboratory markers which are employed in diagnosis and disease assessment; however, colonoscopy remains the most widely used method.

Hereditary Cancer Syndrome in a Family with Double Mutation in and Genes.

Hereditary cancer syndromes predispose to several types of cancer due to inherited pathogenic variants in susceptibility genes. We describe the case of a 57-year-old woman, diagnosed with breast cancer, and her family. The proband belongs to a family with a suspected tumor syndrome, due to other cancer cases in her family from the paternal and maternal sides.

Increased Risk of Hereditary Prostate Cancer in Italian Families with Hereditary Breast and Ovarian Cancer Syndrome Harboring Mutations in and in Other Susceptibility Genes.

Hereditary prostate cancer (HPCa) has the highest heritability of any cancer in men. Interestingly, it occurs in several hereditary syndromes, including breast and ovarian cancer (HBOC) and Lynch syndrome (LS). Several gene mutations related to these syndromes have been identified as biomarkers in HPCa.

Antibody levels after BNT162b2 vaccine booster and SARS-CoV-2 Omicron infection.

In the present study, immunogenicity data in 61 vaccinated healthcare workers (HCWs) either infection naïve (naïve HCWs) or with infection of Delta and/or Omicron COVID-19 (experienced HCWs) were evaluated up to 270 days after the second dose of BNT162b2 vaccine and up to 90 days after a booster dose. A decrease in antibody levels at 270 days following administration of the second dose (p = 0.0335) was observed, although values did not fall below the positivity threshold (33.

Pancreatic Cancer with Mutation in BRCA1/2, MLH1, and APC Genes: Phenotype Correlation and Detection of a Novel Germline BRCA2 Mutation.

Pancreatic ductal adenocarcinoma (PDAC) is the seventh leading cause of cancer death worldwide; most of cases are sporadic, however about 5% to 10% report a hereditary predisposition. Several hereditary syndromes have been associated with familial pancreatic cancer (FPC) onset, including hereditary breast and ovarian cancer syndrome (HBOC), Lynch syndrome (LS), Familial atypical multiple mole melanoma (FAMMM), Familial adenomatous polyposis (FAP), Li-Fraumeni syndrome (LFS), Peutz-Jeghers syndrome (PJS), and Hereditary pancreatitis (HP).The aim of this study was to determine the mutational status of a cohort of 56 HBOC families, 7 LS families, 3 FAP and FAMMM families, and 1 LFS family with at least one case of PDAC.

Diagnostic utility of FGF-23 in mineral bone disorder during chronic kidney disease.

Our data confirm that intact fibroblast growth factor 23 (iFGF-23) concentration is increased in patients with chronic kidney disease (CKD) and that it increases with disease progression (stages I-V). Therefore, iFGF-23 could be considered an early biomarker in the course of chronic kidney disease-mineral bone disorder (CKD-MBD), which has several aspects that make it potentially useful in clinical practice. The availability of an automated method for iFGF-23 assay may represent an added value in the management of the patient with CKD-MBD already from the early stages of the disease, before the increase of the routinely used laboratory parameters, 1-84 parathyroid hormone (PTH) and 25-OH-vitamin D (25-OH-vitD), which occur in more advanced stages of the disease.

Evaluation of neutralizing antibodies after vaccine BNT162b2: Preliminary data.

It is well-known that the Coronavirus Disease 2019, which is caused by the beta-coronavirus severe acute respiratory syndrome (SARS-CoV-2), emerged in December 2019 followed by an outbreak first reported in Wuhan, China. Thus far, vaccination appears to be the only way to bring the pandemic to an end. In the present study, immunogenicity data was evaluated using LIAISON® SARS-CoV-2 TrimericS IgG assay (DiaSorin S.

Seroprevalence of SARS-CoV-2 Antibodies in Adults and Healthcare Workers in Southern Italy.

Background: This study was carried out to estimate the seroprevalence of SARS-CoV-2 antibodies in a Southern Italian population.

Methods: The study was performed among students and workers of the University of Campania "Luigi Vanvitelli" and the relative Teaching Hospital. Participants were invited to undergo a blood sampling, an interview or to complete a self-administered questionnaire.

Hereditary Prostate Cancer: Genes Related, Target Therapy and Prevention.

Prostate cancer (PCa) is globally the second most diagnosed cancer type and the most common cause of cancer-related deaths in men. Family history of PCa, hereditary breast and ovarian cancer (HBOC) and Lynch syndromes (LS), are among the most important risk factors compared to age, race, ethnicity and environmental factors for PCa development. Hereditary prostate cancer (HPCa) has the highest heritability of any major cancer in men.

Prevalence of mutations in BRCA and MMR genes in patients affected with hereditary endometrial cancer.

Endometrial cancer (EC) is the fifth most common cancer in women from developed countries, accounting for 4.8% of new cases and 2.1% of deaths.

Five Italian Families with Two Mutations in Genes.

Double heterozygosity (DH) in and genes and double mutation (DM) in or are extremely rare events in the general population, and few cases have been reported worldwide so far. Here, we describe five probands, all women, with breast and/or ovarian cancer and their families. Particularly, we identified two probands with DH in the genes with a frequency of 0.

Double mutation of APC and BRCA1 in an Italian family.

Familial adenomatous polyposis (FAP) is a rare genetic disorder caused mainly by monoallelic mutations of APC gene. The hereditary breast and ovarian cancer (HBOC) syndrome is an autosomal dominantly inherited disease, which mostly predisposes to breast and ovarian cancers as a result of germline mutations in BRCA1 or BRCA2 genes. In a family, mutations in two cancer susceptibility genes are extremely rare.

BRCA and PALB2 mutations in a cohort of male breast cancer with one bilateral case.

Introduction: Male Breast Cancer (MBC) is a rare disease, about 1% of all breast cancers worldwide and less than 1% of cancers occurring in men. The bilateral male breast cancer (bMBC) is extremely rare. Germline mutations of BRCA1/BRCA2 genes are associated with a significantly increased risk of cancer in MBC; the role of PALB2 remains to be clarified.

and Analysis in FAP Patients: A Novel Mutation in Gene and Genotype-Phenotype Correlation.

and genes are mutated in 70⁻90% and 10⁻30% of familial adenomatous polyposis cases (FAP) respectively. An association between mutation localization and FAP clinical phenotype is reported. The aims of this study were to determine and mutational status in a small cohort of FAP patients and to evaluate the genotype-phenotype correlation in mutated patients.

Antiproliferative, antibacterial and antifungal activity of the lichen Xanthoria parietina and its secondary metabolite parietin.

Lichens are valuable natural resources used for centuries throughout the world as medicine, food, fodder, perfume, spices and dyes, as well as for other miscellaneous purposes. This study investigates the antiproliferative, antibacterial and antifungal activity of the acetone extract of the lichen Xanthoria parietina (Linnaeus) Theodor Fries and its major secondary metabolite, parietin. The extract and parietin were tested for antimicrobial activity against nine American Type Culture Collection standard and clinically isolated bacterial strains, and three fungal strains.

Arg72Pro polymorphism of p53 may predict poor response to medical treatment in ulcerative colitis.

Aim: Arg72Pro is a polymorphism commonly occurring in the proline-rich domain of Tp53. It can determine the development of different types of cancers, such as breast, lung, cervical, colorectal and hepatocellular carcinoma. Previous studies reported a correlation between Pro72 homozygosity and the clinical course of ulcerative colitis (UC).

Analysis of PALB2 in a cohort of Italian breast cancer patients: identification of a novel PALB2 truncating mutation.

PALB2 gene is mutated in about 1-2% of familial breast cancer as well as in 3-4% of familial pancreatic cancer cases. Few studies have reported mutations in Italian patients with breast or pancreatic cancer. We evaluate the occurrence of PALB2 mutations in Italian patients affected with hereditary breast and ovarian cancers and define the pathological significance of the putative allelic variants.

A novel PALB2 truncating mutation in an Italian family with male breast cancer.

Male breast cancer (MBC) is a rare disease, accounting for ~1% of all breast cancer cases worldwide. Although other genes are also involved, predisposing genetic factors to MBC include germline mutations in the BRCA genes (BRCA2). Among the other genes, partner and localizer of BRCA2 (PALB2) is considered a moderate-penetrance breast cancer susceptibility gene that may also play a role in MBC predisposition.

Double heterozygosity in the BRCA1 and BRCA2 genes in Italian family.

Background: Double heterozygosity (DH) is an extremely rare event in which both BRCA1 and BRCA2 are mutated simultaneously in a family. To date, few cases of DH have been reported, especially in Ashkenazi populations. In Italy some cases of DH have been reported.

Identification of a novel in-frame deletion in BRCA2 and analysis of variants of BRCA1/2 in Italian patients affected with hereditary breast and ovarian cancer.

Background: An estimated 5 % – 10 % of all breast cancers are due to an inherited predisposition and, out of these, about 30 % are caused by germline mutations of the BRCA1 and BRCA2 genes. The prevalence of germline mutations in theBRCA1 and BRCA2 genes varies among ethnic groups. The aims of this study are to evaluate deleterious mutations and genomic rearrangements in BRCA1/2 genes and the CHEK21100delC mutation in a cohort of Italian women affected with hereditary breast and/or ovarian cancer.
