Article Abstract
The fight against coronavirus disease 2019 (COVID-19) continues. Since the pandemic's onset, several biomarkers have been proposed to assess the diagnosis and prognosis of this disease. This research aimed to identify potential disease severity biomarkers in serum samples of patients with COVID-19 during the disease course. Data were collected using untargeted and targeted mass spectrometry methods. The results were interpreted by performing univariate and multivariate analyses. Important metabolite classes were identified by qualitative untargeted metabolomics in 15 serum samples from survivors of COVID-19. Quantitative targeted metabolomics on a larger patient cohort including 15 non-survivors confirmed serum 3-sulfate bile acids (i.e. GLCA-3S) were significantly increased in non-survivors compared to survivors during the early disease stage (-value < 0.0001). Notably, it was associated with a higher risk of mortality (odds ratio of 26). A principal component analysis showed the ability to discriminate between survivors and non-survivors using the BA concentrations. Furthermore, increased BA-S is highly correlated with known parameters altered in severe clinical conditions.

Primary biliary cholangitis (PBC) is a rare disease for which management long consisted of a single treatment: ursodeoxycholic acid. In 2015-2016, this disease regained interest with the first studies on obeticholic acid (FXR agonist) and then on bezafibrate (PPAR agonist). Subsequently, over the past five years, significant progress has been made in the management of PBC.

The onset of puberty is increasingly observed at earlier ages in children, especially in girls with obesity, a trend that predisposes them to long-term metabolic and reproductive disorders in adulthood. Bile acids have emerged as pivotal signaling molecules in both metabolic and reproductive disorders, but remain unexplored in the early onset of puberty in children. Herein, we find elevated levels of muricholic acid (MCA) species in the serum of girls with central precocious puberty, which strongly correlate with indices of hypothalamic-pituitary-gonadal axis activation and can reach peak levels during puberty among healthy children.

It is helpful for diagnostic purposes to improve our current knowledge of gut development and serum biochemistry in young piglets. This study investigated serum biochemistry, and gut site-specific patterns of short-chain fatty acids (SCFA) and expression of genes related to barrier function, innate immune response, antioxidative status and sensing of fatty and bile acids in suckling and newly weaned piglets. The experiment consisted of two replicate batches with 10 litters each.

Mitochondria are the cellular powerhouses and are considered to be central to energy metabolism, dynamics, and homeostasis. There is growing evidence that the gut microbiome regulates mitochondrial biogenesis, dynamics (fission, fusion, mitoph-agy), and bioenergetics, and that it does so by connecting bacterial metabolites and signaling molecules. This review discusses the molecular mechanisms that underlie the interplay between bacteria and mitochondria, with a particular focus on the modulation of mitochondrial activities by microbial products, including bile acids, immunological mediators, and short-chain fatty acids (SCFAs).
