ABSTRACT
Introduction: Allergic rhinitis (AR) is a clinical syndrome characterized by IgE-mediated inflam-mation of the nasal mucosa. The present study investigates the quality of life (QoL) with AR among adults, using widely validated questionnaires, unlike in pediatric patients.Materials and methods: A cross-sectional descriptive observational study was conducted, analyzing the QoL of 102 children with AR aged between 10-15 years, belonging to two health centers (HC) in Zaragoza and two HC in Coruña. The comparison of means between the two groups is carried out using the Student's test or the Mann-Whitney test, considering a value of p<0.05 to be significant.Results: Around 102 children were studied, with a majority (59.8%) being male and a mean age of 12 years. Around 76.5% have a family history of atopy. It was found that AR is more prevalent in Zaragoza (p <0.005), and asthmais highly prevalent in Coruña (p <0.001). The most import-ant sensitizations are pollen in Zaragoza (p <0.05) and dust mites in A Coruña (p <0.001). More treatment needs and associated comorbidities (p<0.05) were observed in A Coruña. The results of the ESPRINT-15 show that 63% of the patients have a good QoL, 27% fair, and 8.8%, poor. Those sensitized to mites have a worse score (p = 0.02). It was found that 52% of children expe-rienced improvement during home confinement, with no notable differences between the two populations. The use of the mask favored QoL in patients from Zaragoza (p <0.0 01 (AU)

Syndromic retinal diseases (SRDs) are a group of complex inherited systemic disorders, with challenging molecular underpinnings and clinical management. Our main goal is to improve clinical and molecular SRDs diagnosis, by applying a structured phenotypic ontology and next-generation sequencing (NGS)-based pipelines. A prospective and retrospective cohort study was performed on 100 probands with an a priori diagnosis of non-Usher SRDs, using available clinical data, including Human Phenotype Ontology annotation, and further classification into seven clinical categories (ciliopathies, specific syndromes and five others). Retrospective molecular diagnosis was assessed using different molecular and bioinformatic methods depending on availability. Subsequently, uncharacterized probands were prospectively screened using other NGS approaches to extend the number of analyzed genes. After phenotypic classification, ciliopathies were the most common SRD (35%). A global characterization rate of 52% was obtained, with six cases incompletely characterized for a gene that partially explained the phenotype. An improved characterization rate was achieved addressing prospective cases (83%) and well-recognizable syndrome (62%) subgroups. The 27% of the fully characterized cases were reclassified into a different clinical category after identification of the disease-causing gene. Clinical-exome sequencing is the most appropriate first-tier approach for prospective cases, whereas whole-exome sequencing and bioinformatic reanalysis increases the diagnosis of uncharacterized retrospective cases to 45%, mostly those with unspecific symptoms. Our study describes a comprehensive approach to SRDs in daily clinical practice and the importance of thorough clinical assessment and selection of the most appropriate molecular test to be used to solve these complex cases and elucidate novel associations.

Histone deacetylases (HDACs) influence many cellular processes, including the modulation of signal transducer and activator of transcription activity (STAT) in response to interferon (IFN). To identify genetic markers that help optimize the IL-28B prediction of chronic hepatitis C (CHC) sustained virological response (SVR), we evaluated 27 single-nucleotide polymorphisms (SNPs) in HDAC1-11. Three SNPs, rs3778216, rs976552 and rs368328 in HDAC2, HDAC3 and HDAC5, respectively, were independently associated with SVR (P<0.05). The addition of these three HDAC's SNPs to the IL-28B predictive model (area under the curve (AUC)=0.630) rendered an important improvement of AUC-receiver operating characteristic value (AUC=0.747, P=0.021). Chi-squared Automatic Interaction Detector (CHAID) analysis denoted the significance of the rs3778216 C/C genotype in identifying a group of good responders despite carrying IL-28B T allele (79.2% of SVR), whereas HDAC5 G allele characterized a subgroup with poor response rate (25.5%). However, HDAC3 rs976552 did not display a relevant role for the hierarchical classification of patients. Variables related to SVR in hepatitis C virus genotype 1 (HCV-1) cohort were the same of those obtained for the overall population. Interestingly, in non-HCV-1 patients (n=56) the HDAC2 C/C genotype was the unique predictive variable related to SVR (AUC=0.733, P<0.007). Thus, these preliminary results suggest the potential usefulness of combined IL-28B and HDAC genotyping for the CHC patients' classification by likelihood of an SVR.

Chronic hepatitis C (CHC) is a worldwide health problem that is highly related to liver fibrosis, cirrhosis, and hepatocellular carcinoma. The achievement of response to the current standard of care-pegylated interferon plus ribavirin-has recently been described to be associated with single-nucleotide polymorphisms (SNPs) near the IL-28B gene. Additionally, baseline expression levels of genes involved in interferon (IFN)-stimulated genes (ISGs) have been found to be related to treatment outcome. In the present study, 285 patients were genotyped for 63 SNPs within genes of the IFN signaling pathway (IPGs) and ISGs. Two ISG polymorphisms-OASL rs12819210 (odds ratio (OR)=2.1, P=0.03) and IFIT1 rs304478 (OR=2.5, P=0.01)-were found to be independent predictive factors of sustained virological response (SVR) after adjusting for other clinical covariates. Furthermore, the predictive value of IL-28B SNP was notably improved by simultaneous genotyping of rs12819210 and rs304478, particularly in patients with the worst prognosis (viral genotype 1, area under the curve (AUC)=0.74). In conclusion, ISG SNPs could constitute a valuable tool for individualizing CHC therapy.

BACKGROUND: Hepatitis C virus infection evolves into chronic progressive liver disease in a significant percentage of patients. Monocytes constitute a diverse group of myeloid cells that mediate innate and adaptive immune response. In addition to proinflammatory CD16+ monocytes, a Tie-2+ subgroup - Tie-2 expressing monocytes (TEMs) - that has robust proangiogenic potential has been recently defined. AIM: To study the heterogeneity of peripheral blood monocytes in chronic hepatitis C (CHC) patients and to examine their proposed pathophysiological roles on disease progression and response to antiviral therapy. METHODS: We studied CD16+ and Tie-2+ peripheral monocyte subpopulations in 21 healthy subjects and 39 CHC patients in various stages of disease and responses to antiviral treatment using flow cytometry. Expression profiles of proangiogenic and tissue remodelling factors in monocyte supernatants were measured using ELISA and protein arrays. Intrahepatic expression of CD14, CD31 and Tie-2 was analysed using immunofluorescence. RESULTS: Increases of certain peripheral monocyte subsets were observed in the blood of CHC patients, wherein those cells with proinflammatory (CD16+) or proangiogenic (TEMs) potential expanded (P < 0.005, both). Notably, TEMs were significantly increased in nonresponders, particularly those with lower CD16 expression. In addition, many angiogenic factors were differentially expressed by peripheral monocytes from control or CHC patients, such as angiopoietin-1 and angiogenin (P < 0.05). Interestingly, intrahepatic TEMs were distinguished within portal infiltrates of CHC patients. CONCLUSIONS: These findings suggest for the first time the relevance of peripheral monocytes phenotypes for the achievement of response to treatment. Hence, the study of monocyte subset regulation might effect improved CHC prognoses and adjuvant therapies.

The aim of the study is to investigate the reduction of stress in dogs in municipal shelters through easy-to-implement activities, ie, 25-minute sessions of exercise and human contact, that do not require a significant investment in terms of funding, staff or time. The results demonstrate that the dogs taking part in these sessions have lower salivary cortisol levels (F=121.42; P<0.05) and achieve better scores on a behaviour test (t(17)=4.27; P=0.001). It can therefore be affirmed that the exercise and human contact protocol proposed in the present study diminishes stress and improves the welfare of dogs housed in shelters.

We performed a study to quantify CYP2C9 and CYP2C8 alleles influence on the variability observed in tenoxicam pharmacokinetic (PK) and implication in a bioequivalence study design performed on Spaniards. Eighteen healthy volunteers were included in an open, randomized, crossover, phase I bioequivalence study. Significant increases were found in CYP2C9*3 alleles vs. *1 and *2 in AUC(0-infinity) (median (min-max)): 256 (230-516) vs. 150 (100-268) and 169 (124-197) microg h/mL (p<0.01) and half-life time (t1/2) 102 (79-36) vs. 56 (45-94) and 64 (60-80)h (p<0.01). Non-significant differences were observed in C(max) 1.9 (1.8-2.9) vs. 2.4 (1.7-3.4), 2.5 (1.6-2.9) microg/mL or in according to CYP2C8 alleles presence. CYP2C9*3 allele is associated to a longer elimination time of tenoxicam. PK parameters calculated in bioequivalence studies (AUC(0-infinity), t1/2) may be influenced by the presence of CYP2C9*3 allele resulting in a high variability. Thus, bioequivalence studies of tenoxicam formulations should be designed considering genotype profile.
