Diabetic kidney disease (DKD), an emerging global health issue, is one of the most severe microvascular complications derived from diabetes and a primary pathology contributing to end-stage renal disease. The currently available treatment provides only symptomatic relief and has failed to delay the progression of DKD into chronic kidney disease. Recently, multiple studies have proposed a strong link between intestinal dysbiosis and the occurrence of DKD. The gut microbiota-derived short-chain fatty acids (SCFAs) capable of regulating inflammation, oxidative stress, fibrosis, and energy metabolism have been considered versatile players in the prevention and treatment of DKD. However, the underlying molecular mechanism of the intervention of the gut microbiota-kidney axis in the development of DKD still remains to be explored. This review provides insight into the contributory role of gut microbiota-derived SCFAs in DKD.

Background: Gut microbiota-derived metabolite Trimethylamine-N-oxide (TMAO) is increasingly recognized as a potential novel prognostic biomarker for cardiovascular disease. Our research work aimed to investigate the potential utility of TMAO measurement in patients with STelevation Myocardial Infarction (STEMI).
Methods: We performed a systematic literature search in PubMed from inception to the 1st of February 2024 to identify all studies examining the association between plasma TMAO levels and disease complexity or clinical outcomes in STEMI patients.

Alterations in bile acid profile and pathways contribute to hepatic inflammation in cancer cachexia, a syndrome worsening the prognosis of cancer patients. As the gut microbiota impinges on host metabolism through bile acids, the current study aimed to explore the functional contribution of gut microbial dysbiosis to bile acid dysmetabolism and associated disorders in cancer cachexia. Using three mouse models of cancer cachexia (the C26, MC38 and HCT116 models), we evidenced a reduction in the hepatic levels of several secondary bile acids, mainly taurodeoxycholic (TDCA).

Sepsis is a major cause of morbidity and mortality, but our understanding of the mechanisms underlying survival or susceptibility is limited. Here, as pathogens often subvert host defence mechanisms, we hypothesized that this might influence the outcome of sepsis. We used microbiota analysis, faecal microbiota transplantation, antibiotic treatment and caecal metabolite analysis to show that gut-microbiota-derived tryptophan metabolites including indoles increased host survival in a mouse model of Serratia marcescens sepsis.

Recent reports demonstrate an association between distinct bacteria or bacteria-derived metabolites originating from the gut microbiome and the onset or progression of cardiovascular disease (CVD). This raises the opportunity to modulate the gut microbiome to prevent or treat CVD. To investigate whether intestinal microbiome modulation can prevent or treat CVD, this systematic literature review includes all randomized clinical trials on microbiome modulation and its effects on CVD risk published between August 2018 and August 2023.

Microbiota-derived hydrogen sulfide (HS) plays a crucial role in modulating the gut-brain axis, with significant implications for neurodegenerative diseases such as Alzheimer's and Parkinson's. HS is produced by sulfate-reducing bacteria in the gut and acts as a critical signaling molecule influencing brain health via various pathways, including regulating inflammation, oxidative stress, and immune responses. HS maintains gut barrier integrity at physiological levels and prevents systemic inflammation, which could impact neuroinflammation.
