Decoding the diagnostic and therapeutic potential of microbiota using pan-body pan-disease microbiomics.

The human microbiome emerges as a promising reservoir for diagnostic markers and therapeutics. Since host-associated microbiomes at various body sites differ and diseases do not occur in isolation, a comprehensive analysis strategy highlighting the full potential of microbiomes should include diverse specimen types and various diseases. To ensure robust data quality and comparability across specimen types and diseases, we employ standardized protocols to generate sequencing data from 1931 prospectively collected specimens, including from saliva, plaque, skin, throat, eye, and stool, with an average sequencing depth of 5.

Distinct Patterns of Blood Cytokines Beyond a Cytokine Storm Predict Mortality in COVID-19.

Background: COVID-19 comprises several severity stages ranging from oligosymptomatic disease to multi-organ failure and fatal outcomes. The mechanisms why COVID-19 is a mild disease in some patients and progresses to a severe multi-organ and often fatal disease with respiratory failure are not known. Biomarkers that predict the course of disease are urgently needed.

Intensive smoking diminishes the differences in quality of life and exacerbation frequency between the alpha-1-antitrypsin deficiency genotypes PiZZ and PiSZ.

Background: Alpha-1-antitrypsin deficiency (AATD) is a rare genetic disorder that is associated with low levels of circulating alpha-1-antitrypsin in serum. In comparison to the genotype PiZZ, PiSZ usually leads to lower risk of emphysema, better lung function and better survival. The aim of this study was to analyze the relationship between cigarette smoking (packyears) and the AATD genotypes (PiZZ and PiSZ) concerning quality of life (SGRQ), transfer factor of the lung for carbon monoxide (TLCO), forced expiratory volume in one second (FEV) and exacerbation rate.

Exacerbations and duration of smoking abstinence are associated with the annual loss of FEV in individuals with PiZZ alpha-1-antitrypsin deficiency.

Background: Alpha-1-antitrypsin deficiency (AATD) is a genetic disorder that is associated with a higher risk of chronic obstructive pulmonary disease (COPD) and emphysema. The annual declines in lung function (FEV) and transfer factor of the lung for carbon monoxide (TLCO) predict all-cause mortality.

Material And Methods: We investigated the longitudinal follow-up data over 11 years (mean follow-up period of 4.

Deterioration of quality of life is associated with the exacerbation frequency in individuals with alpha-1-antitrypsin deficiency - analysis from the German Registry.

Background: Alpha-1-antitrypsin deficiency (AATD) is a rare hereditary disease that is associated with a higher risk to develop chronic obstructive pulmonary disease and liver cirrhosis. Previous cross-sectional studies on AATD individuals have shown a relationship between worse St George's Respiratory Questionnaire (SGRQ) scores and elevated exacerbation rate or high cigarette consumption. There is a lack of longitudinal data on the relationship between the exacerbation rate and worsening of SGRQ during disease.

Sex differences in alpha-1-antitrypsin deficiency lung disease-analysis from the German registry.

Alpha-1-antitrypsin deficiency (AATD) is a rare condition with clinical manifestations of the lung and the liver. There is evidence that the gender affects the clinical presentation of non-AATD chronic obstructive lung disease (COPD). The aim of this study was to analyze gender-dependent disease pattern in AATD-based COPD.
