Trend in rifampicin-, multidrug- and extensively drug-resistant tuberculosis in Italy, 2009-2016
2018
In Italy, rifampicin-resistant and MDR-TB were high in foreign-born persons, but decreased from 2009 to 2016
Eight novel variants in the SLC34A2 gene in pulmonary alveolar microlithiasis
2020
BackgroundPulmonary alveolar microlithiasis (PAM) is caused by genetic variants in the SLC34A2 gene, which encodes the sodium-dependent phosphate transport protein 2B (NaPi-2b). PAM is characterised by deposition of calcium phosphate concretions (microliths) in the alveoli leading to pulmonary dysfunction. The variant spectrum of SLC34A2 has not been well investigated and it is not yet known whether a genotype–phenotype correlation exists.MethodsWe collected DNA from 14 patients with PAM and four relatives, and analysed the coding regions of SLC34A2 by direct DNA sequencing. To determine the phenotype characteristics, clinical data were collected and a severity score was created for each va…
Familial pulmonary arterial hypertension by KDR heterozygous loss of function
2020
Beyond the major gene BMPR2, several new genes predisposing to PAH have been identified during the last decade. Recently, preliminary evidence of the involvement of the KDR gene was found in a large genetic association study.We prospectively analysed the KDR gene by targeted panel sequencing in a series of 311 PAH patients referred to a clinical molecular laboratory for genetic diagnosis of PAH.Two index cases with severe PAH from two different families were found to carry a loss-of-function mutation in the KDR gene. These two index cases were clinically characterised by low diffusing capacity for carbon monoxide adjusted for haemoglobin (DLCOc) and interstitial lung disease. In one family,…

P285 The ‘real-life’ copd patient in the age of laba/lamas: an expansion of the daccord study
2016
Introduction The prospective, non-interventional DACCORD study collects data from a representative cohort of COPD out-patients across Germany who either initiated or changed COPD maintenance medication prior to entry. Initially, DACCORD consisted of two treatment groups (Glycopyrronium-based therapy vs. any other COPD maintenance medication with the exception of Glycopyrronium). Following the approval of LABA/LAMA fixed-dose combinations (FDC) in 2013, DACCORD was extended to follow an additional cohort of patients receiving any LABA/LAMA FDC over a period of 2 years. Methods 5223 patients with complete baseline data (3815 LAMA/LABA FDC vs. 1408 standard treatment group) were analysed here.…

Staphylococcus aureusand its IgE-inducing enterotoxins in asthma: current knowledge
2020
While immunoglobulin (Ig) E is a prominent biomarker for early-onset, its levels are often elevated in non-allergic late-onset asthma. However, the pattern of IgE expression in the latter is mostly polyclonal, with specific IgEs low or below detection level albeit with an increased total IgE. In late-onset severe asthma patients, specific IgE to Staphylococcal enterotoxins (se-IgE) can frequently be detected in serum, and has been associated with asthma, with severe asthma defined by hospitalisations, oral steroid use and decrease in lung function. Recently,se-IgE was demonstrated to even predict the development into severe asthma with exacerbations over the next decade.Staphylococcus aureu…
Correlation between work impairment, scores of rhinitis severity and asthma using the MASK-air ® App
2020
Background: In allergic rhinitis, a relevant outcome providing information on the effectiveness of interventions is needed. In MASK-air (Mobile Airways Sentinel Network), a visual analogue scale (VAS) for work is used as a relevant outcome. This study aimed to assess the performance of the work VAS work by comparing VAS work with other VAS measurements and symptom-medication scores obtained concurrently. Methods: All consecutive MASK-air users in 23 countries from 1 June 2016 to 31 October 2018 were included (14 189 users; 205 904 days). Geolocalized users self-assessed daily symptom control using the touchscreen functionality on their smart phone to click on VAS scores (ranging from 0 to 1…
Genetic and Environmental Effects on Telomere Length and Lung Function: A Twin Study.
2015
Background The purpose of the study was to estimate the heritability of leukocyte telomere length (LTL) and lung function and to examine whether LTL and lung function share genetic or environmental effects in common. Methods 386 monozygotic and dizygotic Finnish twin sisters (age 68.4±3.4 years) were included. Relative LTL was determined from peripheral blood DNA by qPCR. Lung function measures of FEV1, FVC, FEV1/FVC, and PEF were derived from spirometry. Genetic modeling was performed with MPlus statistical software. Results Univariate analysis revealed that in LTL, 62% (95% confidence interval 50-72) of the variance was explained by additive genetic and 38% (28-50) by unique environmental…
Variants associated with HHIP expression have sex-differential effects on lung function
2021
Background: Lung function is highly heritable and differs between the sexes throughout life. However, little is known about sex-differential genetic effects on lung function. We aimed to conduct the first genome-wide genotype-by-sex interaction study on lung function to identify genetic effects that differ between males and females. Methods: We tested for interactions between 7,745,864 variants and sex on spirometry-based measures of lung function in UK Biobank (N=303,612), and sought replication in 75,696 independent individuals from the SpiroMeta consortium. Results: Five independent single-nucleotide polymorphisms (SNPs) showed genome-wide significant (P<5x10-8) interactions with sex …
