To assess the environmental status of an abandoned aquaculture and breeding area in the northeast coast of the Hainan Island, surface and well water, sediment and surface soils were sampled and analyzed for conventional physicochemical properties, heavy metals and antibiotics. Metagenome tests were also conducted to determine the composition and diversity of the microbial community in typical habitats. Affected by the discharge of wastewater from higher-place pond aquaculture, coastal freshwater rivers have undergone significant salinization, Cl^- and Na⁺ were as high as 4.51 × 10³ and 1.42 × 10³ mg/L. The 3 hand-pumped wells surveyed were also suffered from varying degrees of salinization and heavy metal pollution, especially the threat of arsenic pollution. Compared with the local background values, significantly higher valves of Cu, Zn, As and Cd were observed in the surface soil and sediment, and the average concentrations for Cu, Zn, As and Cd are 5.71, 17.6, 15.4 and 0.09 mg/kg respectively. For As，the Nemerow index ranges from 7 to 16 and the geoaccumulation index is between 2 and 4, indicating moderate to severe pollution levels in surface soil. 14 antibiotics were detected in the soil and sediment samples, and the highest total amount was 73 μg/kg, with tetracycline being the dominant antibiotic. Sediment and forest soil showed different microbial community and the genetic diversity index of sediment was lower than that of the forest soils. For typical vegetation soil, the genetic diversity followed the order as P. elliottii × P. caribaea > Eucalyptus > C. equisetifolia. Among the soil and sediment samples, the highest abundances of antibiotic resistance genes (ARGs) were associated with elfamycin, peptide, rifamycin, and the most common antibiotic resistance mechanisms were antibiotic target alteration (54.5 %), antibiotic efflux (27.6 %) and antibiotic target replacement (12.1 %). The metal resistance genes (MRGs) for Cu, Fe, and Zn resistance were the main MRGs in the samples. This study identified the potential ecological environment risk factors in the abandoned coastal breeding areas, and suggested continuous monitoring and assessment of the residual pollutant abatement processes in the future.

Impact of different continuous fertilizations on the antibiotic resistome associated with a subtropical triple-cropping system over one decade

Article

Author: Zhou, Chang-Min ; Sun, Li-Li ; Zheng, Jin ; Lu, Yu-Sheng ; Li, Ya-Ying ; Xie, Kai-Zhi ; Gu, Wen-Jie ; Liu, Chong ; Peng, Huan-Long ; Shi, Chao-Hong ; Wang, Dan ; Zhang, Kun

The prevalence of antibiotic resistance genes (ARGs) in agricultural soils has garnered significant attention. However, the long-term impacts of various nitroge (N)-substitution fertilization regimes on the distribution of soil ARGs and their dominant drivers in a subtropical triple-cropping system remain largely unexplored. This study employed a metagenomic approach to analyze soil ARGs, microbial communities, mobile genetic elements (MGEs), and viruses from a maize-maize-cabbage rotation field experiment with five different fertilization regimes. Soil samples were collected in 2012 and 2021. A total of 615 unique ARG subtypes were identified, with multidrug, bacitracin, and rifamycin resistance genes being the most abundant. Notably, ARG types. the continuous application of fresh chicken manure (CM) over 10 years significantly increased both the count of unique ARG subtypes and the total ARG abundance compared to other fertilization regimes, such as inorganic fertilizer and composted chicken manure. Specifically, the abundance of genes associated with antibiotic target replacement (e.g., sul1 and sul2) in the CM-treated soil rose by 8.83-fold from 2021 to 2012. Our random forest analysis revealed that the abundance of three MGEs (QacEdelta, plasmids, and IstB), two viral families (Myoviridae and Podoviridae), two bacterial phyla (Chloroflexi and Planctomycetes), and two environmental factors (pH and soil organic matter (SOM)) significantly influenced the distribution of ARGs. Furthermore, variance decomposition analysis underscored the critical roles of the three MGEs and the two viral families in the dissemination of ARGs, suggesting that horizontal gene transfer (HGT) may play a key role in ARG spread. These findings enhance our understanding of how different fertilization practices influence ARG dissemination in subtropical triple-cropping agroecosystems over the long term and provide valuable insights for optimizing fertilization management strategies.

Continuous carbon source supply is essential for high rifamycin productivity of <italic>Amycolatopsis mediterranei</italic> in nitrate-stimulated fermentation revealed by a metabolomic study

Article

Author: Yang, Chen ; Shao, Zhihui ; Yan, Qi ; Zhao, Guoping

Amycolatopsis mediterranei U32 is an industrial strain capable of producing therapeutically useful rifamycin SV. In early days of fermentation studies, nitrate was found to increase the yield of rifamycin along with globally, affecting both carbon and nitrogen metabolism in favor of antibiotic biosynthesis; thus, the nitrate-stimulating effect (NSE) hypothesis was proposed. Although GlnR is likely the master regulator of the pleotropic effect of NSE, the global metabolism affected by NSE has never been systematically examined. In this study, we use mass spectrometry-based metabolomics to quantitatively monitor the metabolomic responses of A. mediterranei U32 to nitrate supplementation. The concentrations of many metabolites involved in central carbon metabolism, including glucose 6-phosphate, glucose 1-phosphate, UDP-glucose, and acetyl-coenzyme A, decrease significantly after the addition of 80 mM potassium nitrate to the medium. We find that the rifamycin SV production yield could be increased by the addition of glucose during the logarithmic growth phase. Moreover, at multiple time points during glucose supplementation in the mid- and late-exponential phases, the yield of rifamycin SV further increases, reaching 354.3%. Quantitative real-time PCR assays of the key genes corresponding to the synthesis of the rifamycin SV precursor combined with data from metabolomics analysis confirm that carbon source deficiency is compensated for after glucose supplementation and that the expression of genes involved in the pathway of 3-amino-5-hydroxybenzoic acid synthesis by UDP-glucose and glutamine is significantly increased. This preliminary exploration of dynamic metabolomic profiles has the potential to increase our understanding of the NSE.

RedHill's Talicia® Adds 8 Million Lives With Coverage by Humana®'s Part D Plan. Also, New Data Supporting Simplified Three-Times Daily Talicia Dosing Published

Talicia is now covered by Humana's Part D Plan, providing access to Talicia for H. pylori therapy to more than eight million additional Medicare lives, without requiring prior therapeutic steps or authorization The recently updated American College of Gastroenterology (ACG) Clinical Guideline lists Talicia as a first-line option for treatment of H. pylori infection. Talicia continues to be the most prescribed branded H. pylori therapy by U.S. gastroenterologists Additionally, new data describing the foundations for Talicia's recent FDA-approved label change to a more convenient three-times daily (TID) "breakfast, lunch, and dinner" dosing routine, supporting patient adherence, has been published in the Journal of Clinical Pharmacology The published data describe the use of physiologically-based pharmacokinetic (PBPK) modeling and simulation to demonstrate pharmacokinetic equivalence of the TID regimen to the previous every 8-hour (Q8H) dosing regimen H. pylori infection affects approximately 35% of the U.S. adult population and is classified by the World Health Organization (WHO) as a Group 1 carcinogen, being the strongest known risk factor for gastric cancer and a major risk factor for peptic ulcer disease RALEIGH, N.C. and TEL-AVIV, Israel, Jan. 21, 2025 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced the coverage of Talicia by Humana's Part D Plan, providing access to Talicia for H. pylori therapy to more than eight million additional Medicare lives, without the requirement for prior therapeutic steps or authorizations, for both treatment-naïve and treatment-experienced patients, effective as of January 1, 2025. "There is broad recognition of the clinical efficacy of Talicia and the recently updated American College of Gastroenterology (ACG) Clinical Guideline, listing Talicia as a first-line treatment option. Talicia is the only FDA-approved low-dose rifabutin-based therapy for the eradication of H. pylori, and continues to be the most prescribed branded H. pylori therapy by U.S. gastroenterologists1," said Rick D. Scruggs, President and Chief Commercial Officer of RedHill Biopharma, Inc. "We are pleased that coverage in the Medicare arena is growing as the Part D payers recognize the importance of treating H. pylori with the right therapy the first time and look forward to expanding coverage in Medicare." The Company also announced the publication of new data in The Journal of Clinical Pharmacology2. The published data describe the foundations for Talicia's recently FDA-approved label change to a more convenient three-times daily (TID) with food (at least 4 hours apart, e.g., breakfast, lunch, and dinner) dosing routine, further simplifying the patient experience and supporting increased patient adherence. The result of a successful collaboration with Certara, the published study utilized Certara's Simcyp™ Simulator for physiologically-based pharmacokinetic (PBPK) modeling and simulation to demonstrate pharmacokinetic equivalence in plasma and within the stomach for all three of Talicia's components, regardless of dosing TID or Q8H. These data support the provision of a more patient-friendly Talicia regimen and further demonstrate RedHill's ongoing commitment to enhanced patient experience and outcomes. "Treating H. pylori infection is challenging and often requires patients to take multiple different pills multiple times a day. Simplified dosing regimens improve patient adherence. In the treatment of H. pylori infection, adherence to dosing is critical for optimizing patient outcomes, while also mitigating against the development of bacterial resistance. Therefore, it is important to use an effective therapy that is most likely to eradicate H. pylori infection at the first attempt," said Colin W. Howden, MD, Professor Emeritus, University of Tennessee College of Medicine, and co-author of the paper. "These important data, and the retention of Talicia's pharmacokinetic profile across dosing regimens, support the change to a more simplified TID dosing schedule. Talicia's efficacy, tolerability, and resistance profile, along with its convenient all-in-one formulation and TID dosing, further support its inclusion as an empirically prescribed first-line option in the 2024 ACG Clinical Guideline on the treatment of H. pylori infection3." About H. pylori H. pylori is a bacterial infection that affects approximately 35%4 of the U.S. population, with an estimated two million patients treated annually3. Worldwide, around 66% of the population has H. pylori infection5, which is classified by the World Health Organization (WHO) as a Group 1 carcinogen. It remains the strongest known risk factor for gastric cancer6 and a major risk factor for peptic ulcer disease7 and gastric mucosa-associated lymphoid tissue (MALT) lymphoma8. More than 27,000 Americans are diagnosed with gastric cancer annually9. Eradication of H. pylori is becoming increasingly difficult, with current therapies failing in approximately 25-40% of patients who remain H. pylori-positive due to high resistance of H. pylori to antibiotics – especially clarithromycin – which is still commonly used in standard combination therapies10. About Talicia® Talicia is the only low-dose rifabutin-based therapy approved for the treatment of H. pylori infection and is designed to address the high resistance of H. pylori bacteria seen with other antibiotics. More specifically, the high rates of H. pylori resistance to clarithromycin have led to significant increases in treatment failures with clarithromycin-based therapies and are a strong public health concern, as highlighted by the ACG, FDA and the WHO in recent years. Talicia is a novel, fixed-dose, all-in-one oral capsule combination of two antibiotics (amoxicillin and rifabutin) and a proton pump inhibitor (PPI) (omeprazole). In November 2019, Talicia was approved by the U.S. FDA for the treatment of H. pylori infection in adults. In the pivotal Phase 3 study, Talicia demonstrated 84% eradication of H. pylori infection in the intent-to-treat (ITT) group vs. 58% in the active comparator arm (p<0.0001). Minimal to zero resistance to rifabutin, a key component of Talicia, was detected in RedHill's pivotal Phase 3 study. Further, in an analysis of data from this study, it was observed that subjects who were confirmed adherent11 to their therapy had response rates of 90.3% in the Talicia arm vs. 64.7% in the active comparator arm12. Talicia is eligible for a total of eight years of U.S. market exclusivity under its Qualified Infectious Disease Product (QIDP) designation and is also covered by U.S. patents which extend patent protection until 2034 with additional patents and applications pending and granted in various territories worldwide. Patients should check coverage details with their health plan. TALICIA: INDICATION AND IMPORTANT SAFETY INFORMATION Talicia is a three-drug combination of omeprazole, a proton pump inhibitor, amoxicillin, a penicillin-class antibacterial, and rifabutin, a rifamycin antibacterial, indicated for the treatment of Helicobacter pylori infection in adults. To reduce the development of drug-resistant bacteria and maintain the effectiveness of Talicia and other antibacterial drugs, Talicia should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.

IMPORTANT SAFETY INFORMATION XIFAXAN is contraindicated in patients with a hypersensitivity to rifaximin, rifamycin antimicrobial agents, or any of the components in XIFAXAN. Hypersensitivity reactions have included exfoliative dermatitis, angioneurotic edema, and anaphylaxis. Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including XIFAXAN, and may range in severity from mild diarrhea to fatal colitis. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. There is an increased systemic exposure in patients with severe (Child-Pugh Class C) hepatic impairment. Caution should be exercised when administering XIFAXAN to these patients. Caution should be exercised when concomitant use of XIFAXAN and P-glycoprotein (P-gp) and/or OATPs inhibitors is needed. Concomitant administration of cyclosporine, an inhibitor of P-gp and OATPs, significantly increased the systemic exposure of rifaximin. In patients with hepatic impairment, a potential additive effect of reduced metabolism and concomitant P-gp inhibitors may further increase the systemic exposure to rifaximin. In clinical studies, the most common adverse reactions for XIFAXAN (alone or in combination with lactulose) were: HE (≥10%): Peripheral edema (17%), constipation (16%), nausea (15%), fatigue (14%), insomnia (14%), ascites (13%), dizziness (13%), urinary tract infection (12%), anemia (10%), and pruritus (10%) IBS-D (≥2%): Nausea (3%), ALT increased (2%) INR changes have been reported in patients receiving rifaximin and warfarin concomitantly. Monitor INR and prothrombin time. Dose adjustment of warfarin may be required. XIFAXAN may cause fetal harm. Advise pregnant women of the potential risk to a fetus. XIFAXAN is contraindicated in patients with a hypersensitivity to rifaximin, rifamycin antimicrobial agents, or any of the components in XIFAXAN. Hypersensitivity reactions have included exfoliative dermatitis, angioneurotic edema, and anaphylaxis. Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including XIFAXAN, and may range in severity from mild diarrhea to fatal colitis. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. There is an increased systemic exposure in patients with severe (Child-Pugh Class C) hepatic impairment. Caution should be exercised when administering XIFAXAN to these patients.

RedHill Announces New U.S. Coronavirus Patent for Opaganib, Valid Through 2041

New U.S. patent issued covering the identification of a novel biomarker of coronavirus pneumonia (≤60% fraction of inspired oxygen (FiO2)) prognostic for potential opaganib efficacy in treating COVID-19, valid through 2041 Published post-hoc data from opaganib's Phase2/3 study showed that patients with ≤60% FiO2 levels had better outcomes after 14 days' opaganib treatment (n=117) compared to placebo (n=134), including: increased number of patients no longer requiring supplemental oxygen by day 14 of opaganib treatment (76.9% vs. 63.4%; p-value =0.033), a 62.6% reduction in intubation/mechanical ventilation (6.84% vs. 17.91%; p-value=0.012) and a clinically meaningful 62% reduction in mortality (5.98% vs. 16.7%; p-value=0.019) by day 42[1] With multiple U.S. government collaborations for medical countermeasure and pandemic preparedness, opaganib is a novel, host-directed, potentially broad acting, orally administered small molecule drug with demonstrated safety & efficacy profiles, being developed for various oncology, viral infections, inflammatory diseases and nuclear/radioprotection indications TEL-AVIV, Israel and RALEIGH, N.C., Sept. 30, 2024 /PRNewswire/ -- RedHill Biopharma Ltd. (Nasdaq: RDHL) ("RedHill" or the "Company"), a specialty biopharmaceutical company, today announced the issue of a new U.S. patent for identification of a novel biomarker of coronavirus pneumonia (≤60% fraction of inspired oxygen (FiO2)) prognostic for potential opaganib[2] efficacy in treating COVID-19, valid through 2041 (U.S. Patent and Trademark Office Number: 12,115,150, date of grant to be: October 15, 2024). Guy Goldberg, RedHill's Chief Business Officer, said: "This exciting new patent is based on compelling published post-hoc data from opaganib's Phase 2/3 study, showing that patients with ≤60% FiO2 levels had better outcomes after 14 days' opaganib treatment. These outcomes included an increase in patients no longer requiring supplemental oxygen by day 14 of opaganib treatment, a reduction in patients requiring intubation/mechanical ventilation and a clinically meaningful 62% reduction in mortality. This is a very interesting addition to the already strong patent portfolio protecting opaganib." About Opaganib (ABC294640) Opaganib, a proprietary investigational host-directed and potentially broad-acting drug, is a first-in-class, orally administered sphingosine kinase-2 (SPHK2) selective inhibitor with anticancer, anti-inflammatory and antiviral activity, targeting multiple potential indications, including several cancers, diabetes and obesity-related disorders, gastrointestinal acute radiation syndrome (GI-ARS), Sulfur Mustard exposure, COVID-19, Ebola and other viruses as part of pandemic preparedness. Opaganib's host-directed action is thought to work through the inhibition of multiple pathways, the induction of autophagy and apoptosis, and disruption of viral replication, through simultaneous inhibition of three sphingolipid-metabolizing enzymes in human cells (SPHK2, DES1 and GCS). Several U.S. government countermeasures and pandemic preparedness programs have selected opaganib for evaluation for multiple indications, including Acute Radiation Syndrome (ARS), Ebola virus disease and others Funding bodies include the Radiation and Nuclear Countermeasures Program (RNCP), led by the National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S. government Department of Health & Human Services' National Institutes of Health and the Administration for Strategic Preparedness and Response's (ASPR) Center for Biomedical Advanced Research and Development Authority (BARDA). Opaganib has demonstrated antiviral activity against SARS-CoV-2, multiple variants, and several other viruses, such as Influenza A and Ebola. Opaganib delivered a statistically significant increase in survival time when given at 150 mg/kg twice a day (BID) in a United States Army Medical Research Institute of Infectious Diseases (USAMRIID) in vivo Ebola virus study, making it the first host-directed molecule to show activity in Ebola virus disease. Opaganib also recently demonstrated a distinct synergistic effect when combined individually with remdesivir (Veklury®, Gilead Sciences Inc.), significantly improving potency while maintaining cell viability, in a U.S. Army-funded and conducted in vitro Ebola virus study. Being host-targeted, and based on data accumulated to date, opaganib is expected to maintain effect against emerging viral variants. In prespecified analyses of Phase 2/3 clinical data in hospitalized patients with moderate to severe COVID-19, oral opaganib demonstrated improved viral RNA clearance, faster time to recovery and significant mortality reduction in key patient subpopulations versus placebo on top of standard of care. Opaganib has demonstrated its safety and tolerability profile in more than 470 people in multiple clinical studies and expanded access use. Data from the opaganib global Phase 2/3 study was published in Microorganisms. Opaganib has received several orphan-drug designations from the FDA in oncology and other diseases and has undergone studies in advanced cholangiocarcinoma (Phase 2a) and prostate cancer. Opaganib also has a Phase 1 chemoradiotherapy study protocol ready for FDA-IND submission. Opaganib has also shown positive preclinical results in renal fibrosis, and has the potential to target multiple oncology, radioprotection, viral, inflammatory, and gastrointestinal indications.
