The diagnosis of Invasive Fungal Disease (IFD) is difficult because the sensitivity of conventional culture and cytology methods for the detection of Aspergillus is poor, and because serological methods exhibit cross-reactivity with environmental fungi. Fungal polysaccharides are of particular interest in the serologic diagnosis of IFD, especially galactomannan (GM) and glucan, which have been recognized as useful tools for the diagnosis of fungal infections. Further investigation into polysaccharide antibody cross-reactivity is important in improving diagnostic tests. Our aim was to verify the production of antibodies against fungal antigens in mice immunized with exopolysaccharides (EPS) obtained from three fungal species (Aspergillus terreus, Paecilomyces variotii and Curvularia brachyspora). ELISA assays were performed to evaluate homologous and heterologous reactions and showed anti-polysaccharide antibodies production. EPS from A. terreus was immunogenic enough to immunize the animal and lead to antibody production against this EPS. In addition, no cross-reactivity was observed with EPS obtained from P. variotii and C. brachyspora. The EPS from P. variotii did not exhibit good immunogenicity, whereas EPS from C. brachyspora showed good immunogenicity, and heterologous reactions were detected on the ELISA assays performed using the EPS from this species. The results indicate that immunization can occur for environmental fungal polysaccharides, generating antibodies may be interfere in serological diagnosis that are based on detection of fungal polysaccharides, mainly glucans and galactomannans.

Background: Oxidative stress has been implicated in the progression of severe forms of non-alcoholic fatty liver disease(NAFLD). NADPH oxidase produces reactive oxygen species. In the present study, we investigated for the first time two single nucleotide polymorphisms(SNPs) in the regulatory region of genes encoding NADPH oxidase 4(NOX4) and p22 phox(CYBA) in ***: A total of 207 biopsy-proven NAFLD patients [simple steatosis(n = 27); nonalcoholic steatohepatitis(NASH)(n = 180)] were evaluated. Genomic DNA was extracted from peripheral blood cells, and polymorphisms in CYBA(unregistered) and NOX4(rs3017887) were determined by direct sequencing of ***: Associations of CYBA-675 T/A with high-density lipoprotein(HDL)(TT vs TA vs AA; P des(TGL)(TT vs XA; P degrees of fibrosis occurred in patients diagnosed with type 2 diabetes mellitus(66.9% vs 37.5%, P degrees of fibrosis in NAFLD patients.

AIM To assess lactase gene(LCT)-13910C>T polymorphisms in Brazilian non-alcoholic fatty liver disease(NAFLD) and nonalcoholic steatohepatitis(NASH) patients in comparison with healthy *** This was a transverse observational clinical study with NAFLD patients who were followed at the Hepatology Outpatient Unit of the Hospital das Clínicas, S?o Paulo, Brazil. The polymorphism of lactase non-persistence/lactase persistence(LCT-13910C>T) was examined by PCR-restriction fragment length polymorphism technique in 102 liver biopsy-proven NAFLD patients(steatosis in 9 and NASH in 93) and compared to those of 501 unrelated healthy volunteers. Anthropometric, clinical, biochemical and liver histology data were analyzed. Continuous variables were compared using the t or Mann-Whitney tests, and categorical data were compared with the Fisher's exact test. Univariate logistic regression and multivariate logistic regression adjusted for gender and age were *** No differences in the LCT-13910 genotype frequencies were noted between the NAFLD patients(66.67% of the patients with steatosis were CC, 33.33% were CT, and none were TT; 55.91% of the patients with NASH were CC, 39.78% were CT, and 4.3% were TT; P = 0.941) and the healthy controls(59.12% were CC, 35.67% were CT, and 5.21% were TT) or between the steatosis and NASH patients. That is, the distribution of the lactase non-persistence/lactase persistence polymorphism(LCT-13910C>T) in the patients with NAFLD was equal to that in the general population. In the NASH patients, the univariate analysis revealed that the lactase nonpersistence(low lactase activity or hypolactasia) phenotype was associated with higher insulin levels(23.47 ± 15.94 μU/m L vs 15.8 ± 8.33 μU/m L, P = 0.027) and a higher frequency of insulin resistance(91.84% vs 72.22%, P = 0.02) compared with the lactase persistence phenotype. There were no associations between the LCT genotypes and diabetes(P = 0.651), dyslipidaemia(P = 0.328), h
