Pathogenic mycobacterium upregulates cholesterol 25-hydroxylase to promote granuloma development via foam cell formation
iScience. 2024 Feb 12;27(3):109204. doi: 10.1016/j.isci.2024.109204. eCollection 2024 Mar 15.ABSTRACTPathogenic mycobacteria orchestrate the complex cell populations known as granuloma that is the hallmark of tuberculosis. Foam cells, a lipid-rich cell-type, are considered critical for granuloma formation; however, the causative factor in foam cell formation remains unclear. Atherosclerosis is a chronic inflammatory disease characterized by the abundant accumulation of lipid-laden-macrophage-derived foam cells during which cholesterol 25-hydroxylase (CH25H) is crucial in foam cell formation. Here, we show that M. marinum (...

An atorvastatin ‐induced positive anti‐HMGCR immune‐mediated necrotizing myopathy case
Key Clinical MessageStatins can commonly cause myopathy. Most of the time, stopping the culprit drug should solve the problem. However, if the drug has been discontinued but muscle weakness continues to worsen, immune-mediated myopathy should be taken into consideration. (Source: Clinical Case Reports)

Zhuyu Pills promote polarization of macrophages toward M2 phenotype to prevent atherosclerosis via PPARgamma/NF-kappaB signaling pathway
In conclusion, Zhuyu Pills may play an anti-atherosclerosis role by regulating PPARγ/NF-κB signaling pathway, inhibiting the polarization of macrophages toward the M1 phenotype, promoting the polarization of macrophages toward the M2 phenotype, and improving the inflammatory microenvironment of macrophages.PMID:38403357 | DOI:10.19540/j.cnki.cjcmm.20230823.501 (Source: Atherosclerosis)

Environmentally relevant concentrations of aqueous atorvastatin produce alterations in cholesterol biosynthesis and gene expression patterns in Xenopus laevis
Aquat Toxicol. 2024 Feb 5;269:106856. doi: 10.1016/j.aquatox.2024.106856. Online ahead of print.ABSTRACTNumerous studies report active pharmaceutical compounds detected in both wastewater effluent and surface waters. Exposure to statin drugs in general, and atorvastatin in particular, is likely to be a concern. We hypothesized that chronic exposure to low concentrations of atorvastatin in water would result in an adverse effect on production of steroids regulating growth and development of the model amphibian Xenopus laevis. The FETAX assay was used to evaluate the effects of a range of doses of atorvastatin on developing ...

Atorvastatin for reduction of 28-day mortality in severe and critical COVID-19 patients: a randomized controlled trial
CONCLUSIONS: In adults with severe or critical COVID-19, atorvastatin did not reduce the risk of 28-day or 6-month mortality and did not shorten the length of hospital stay or time to clinical improvement. Trial registration Clinical Trial Registry (NCT04952350) on July 1st, 2021. https://clinicaltrials.gov/ct2/show/NCT04952350.PMID:38389078 | PMC:PMC10885389 | DOI:10.1186/s12931-024-02732-2 (Source: Respiratory Care)

Assessment of drug utilization and potentially inappropriate medications in hemodialysis patients with end-stage renal dysfunction: A study in a tertiary care hospital in Bahrain
CONCLUSION: A huge burden of drug therapy was observed in the hemodialysis patients in terms of higher proportions of PIM, complex medical regimen, and prescription of drugs with risk of TdP. Implementation of clinical decision support tools enhancing rational prescription and identification of drugs with TdP risk, introducing antimicrobial stewardship, and stepwise deprescription of the drugs with the least benefit-risk ratio are warranted.PMID:38393922 | DOI:10.3233/JRS-230004 (Source: International Journal of Risk and Safety in Medicine)
