RESUMO
Cardio-metabolic disease is a significant global health challenge with increasing prevalence. Recent research underscores the disruption of gut microbial balance as a key factor in disease susceptibility. We aimed to characterize the gut microbiota composition and function in cardio-metabolic disease and healthy controls. For this purpose, we collected stool samples of 18 subjects (12 diseased, 6 healthy) and we performed metagenomics analysis and functional prediction using QIIME2 and PICRUSt. Furthermore, we carried out assessments of microbe-gene interactions, gene ontology, and microbe-disease associations. Our findings revealed distinct microbial patterns in the diseased group, particularly evident in lower taxonomic levels with significant variations in 14 microbial features. The diseased cohort exhibited an enrichment of Lachnospiraceae family, correlating with obesity, insulin resistance, and metabolic disturbances. Conversely, reduced levels of Clostridium, Gemmiger, and Ruminococcus genera indicated a potential inflammatory state, linked to compromised butyrate production and gut permeability. Functional analyses highlighted dysregulated pathways in amino acid metabolism and energy equilibrium, with perturbations correlating with elevated branch-chain amino acid levels-a known contributor to insulin resistance and type 2 diabetes. These findings were consistent across biomarker assessments, microbe-gene associations, and gene ontology analyses, emphasizing the intricate interplay between gut microbial dysbiosis and cardio-metabolic disease progression. In conclusion, our study unveils significant shifts in gut microbial composition and function in cardio-metabolic disease, emphasizing the broader implications of microbial dysregulation. Addressing gut microbial balance emerges as a crucial therapeutic target in managing cardio-metabolic disease burden.
RESUMO
A 21-year-old woman was admitted to the department of haematology with fever, generalised body ache and swelling of the feet. She also presented with band-like tightness over the abdomen and was unable to walk for the last 2 days. There was no history of trauma. She was diagnosed as a case of B-cell acute lymphoblastic leukaemia based on flow cytometry and bone marrow studies. MRI of the thoracolumbar spine revealed signal intensity alteration in the spinal cord from D1-2 to D5-6. Her serum vitamin B12 and folate levels were normal. Autoimmune workup including antinuclear antibody and viral serology, and reverse transcriptase PCR for herpes simplex virus, Epstein-Barr virus and cytomegalovirus were negative. Her cerebrospinal fluid was negative for malignant cells. She was started on Berlin-Frankfurt-Munster 95 protocol and her condition improved along with partial improvement in the power of her limbs at the time of discharge. The neurological diagnosis of non-compressive myelopathy due to myelitis was considered.
