Colorimetric aptasensor for tobramycin based on a highly stabilized aptamer-enhanced enzyme-mimicking activity of iron oxide/graphene oxide nanospheres

Article

Author: Ding, Tao ; Tai, Shengmei ; Agyekum, Akwasi Akomeah ; Mao, Minxin ; Wang, Zhouping ; Sun, Chengdong ; Peng, Chifang ; Barimah, Alberta Osei

Antibiotic contaminants in food are associated with detrimental health issues, and thus, the design of rapid and reliable detection methods to monitor them is in high demand. Although colorimetric aptamer sensing methods can achieve accurate and quick visual read-out analysis, they still have morphological defects that affect the detection efficiency and stability of the aptasensor. Hence, a simple and highly selective iron oxide/graphene oxide (Fe₃O₄/GO) nanospheres was developed and modified with an aptamer as nanozymes for colorimetric detection of tobramycin (Tob). Due to the electrostatic and π-π stacking interaction between the aptamer and the spherical Fe₃O₄/GOs nanozyme, the catalytic activity of the nanozyme was enhanced by the robust affinity between the aptamer and the 3,3',5,5'-tetramethylbenzidine (TMB) substrate. However, the presence of Tob could obstruct the catalytic activity through the specific binding of aptamer to Tob and the detachment of aptamer from the surface of the Fe₃O₄/GO, causing a low catalytic activity. Based on this strategy, a visual and quantitative detection for Tob was achieved with a detection limit of 70.7 nM. The proposed aptasensor demonstrated high selectivity, ease of operation, and potential application in food samples with satisfactory recoveries of 98.4-108.5 %. Therefore, this proposed method has great prospects for monitoring food safety and could be applied for sensing varied antibiotics by just switching the target-specific aptamer.

Unravelling the potential of natural chelating agents in the control of Staphylococcus aureus and Pseudomonas aeruginosa biofilms

Article

Author: Borges, Anabela ; Gonçalves, Ariana S C ; Borges, Fernanda ; Simões, Manuel ; Moreira, Joana ; Leitão, Miguel M ; Fernandes, Carlos

Iron is essential for the formation, maturation and dispersal of bacterial biofilms, playing a crucial role in the physiological and metabolic functions of bacteria as well as in the regulation of virulence. Limited availability of iron can impair the formation of robust biofilms by altering cellular motility, hydrophobicity and protein composition of the bacterial surface. In this study, the antibiofilm activity of two natural iron chelating agents, kojic acid (5-hydroxy-2-hydroxymethyl-4H-pyran-4-one) and maltol (3-hydroxy-2-methyl-4-pyrone), were investigated against Staphylococcus aureus and Pseudomonas aeruginosa. In addition, the ability of these 2-hydroxy-4-pyrone derivatives in preventing and eradicating S. aureus and P. aeruginosa biofilms through the enhancement of the efficacy of two antibiotics (tobramycin and ciprofloxacin) was explored. The iron binding capacity of the kojic acid and maltol was confirmed by their affinity for iron (III) which was found to be about 90 %, comparable to the regular chelating agent ethylenediaminetetraacetic acid (EDTA, 89 %). The antibiofilm efficacy of 2-hydroxy-4-pyrone derivatives, alone and in combination with antibiotics, was evaluated by measuring the total biomass, metabolic activity, and culturability of biofilm cells. Furthermore, their impact on the membrane integrity of S. aureus biofilm cells was investigated using flow cytometry and epifluorescence microscopy with propidium iodide staining. It was also examined the ability of 2-hydroxy-4-pyrone derivatives and 2-hydroxy-4-pyrone derivate-antibiotic dual-combinations in inhibiting the production of virulence factors (total proteases, lipases, gelatinases and siderophores) by S. aureus. Regarding biofilm formation, the results showed that 2-hydroxy-4-pyrone derivatives alone reduced the metabolic activity of S. aureus biofilm cells by over 40 %. When combined with tobramycin, a 2-log (CFU cm^-2) reduction in S. aureus biofilm cells was observed. Moreover, the combination of maltol and kojic acid with ciprofloxacin prevented P. aeruginosa biomass production by 60 %, compared to 36 % with ciprofloxacin alone. In pre-established S. aureus and P. aeruginosa biofilms, selected compounds reduced the metabolic activity by over 75 %, and a 3-log (CFU cm^-2) reduction in the culturability of biofilm cells was noted when kojic acid and maltol were combined with antibiotics. Moreover, 2-hydroxy-4-pyrone derivatives alone and in combination with tobramycin, damaged the cell membranes of pre-established biofilms and completely inhibited total proteases production. Despite the increasing of reactive oxygen species production caused by the cellular treatment of maltol, both 2-hydroxy-4-pyrone derivatives showed good safe profile when tested in human hepatocarcinoma (HepG2) cells. The pre-treatment of HepG2 cells with both compounds was crucial to prevent the cellular damage caused by iron (III). This study demonstrates for the first time that the selected 2-hydroxy-4-pyrone derivatives significantly enhance the antibiofilm activity of tested antibiotics against S. aureus and P. aeruginosa, highlighting their potential as antibiotic adjuvants in preventing and eradicating biofilm-related infections.

Tobramycin-resistant small colony variant mutant of Salmonella enterica serovar Typhimurium shows collateral sensitivity to nitrofurantoin

Article

Author: Xu, Jin-Peng ; Zhang, Yue-Jun ; Sun, Jian ; Wang, Chang-Zhen ; Fang, Liang-Xing ; Long, Teng-Fei ; Zhou, Yu-Feng ; Chu, Yue-Fei ; Liao, Xiao-Ping ; Zhong, Long-Gen ; Liang, Liu-Yan

The increasing antibiotic resistance poses a significant global health challenge, threatening our ability to combat infectious diseases. The phenomenon of collateral sensitivity, whereby resistance to one antibiotic is accompanied by increased sensitivity to another, offers potential avenues for novel therapeutic interventions against infections unresponsive to classical treatments. In this study, we elucidate the emergence of tobramycin (TOB)-resistant small colony variants (SCVs) due to mutations in the hemL gene, which render S. Typhimurium more susceptible to nitrofurantoin (NIT). Mechanistic studies demonstrate that the collateral sensitivity in TOB-resistant S. Typhimurium SCVs primarily stems from disruptions in haem biosynthesis. This leads to dysfunction in the electron transport chain (ETC) and redox imbalance, ultimately inducing lethal accumulation of reactive oxygen species (ROS). Additionally, the upregulation of nfsA/B expressions facilitates the conversion of NIT prodrug into its active form, promoting ROS-mediated bacterial killing and contributing to this collateral sensitivity pattern. Importantly, alternative NIT therapy demonstrates a significant reduction of bacterial load by more than 2.24-log₁₀ cfu/g in the murine thigh infection and colitis models. Our findings corroborate the collateral sensitivity of S. Typhimurium to nitrofurans as a consequence of evolving resistance to aminoglycosides. This provides a promising approach for treating infections due to aminoglycoside-resistant strains.

Sound Pharma Announces Positive Phase 3 Results for the Treatment of Meniere’s Disease with SPI-1005

SEATTLE--( BUSINESS WIRE )--Sound Pharmaceuticals is pleased to announce that the pivotal Phase 3 clinical trial involving SPI-1005, a novel anti-inflammatory compound (ebselen), for the treatment of Meniere’s Disease (STOPMD-3), achieved its co-primary endpoints for efficacy involving improvements in hearing loss and speech discrimination. Meniere’s disease (MD) is an inner ear disorder that involves fluctuating hearing loss and tinnitus, and episodic vertigo and/or dizziness. There are no FDA-approved medical treatments for MD, nor for the treatment of hearing loss, tinnitus, vertigo, or dizziness. SPI-1005 is an oral capsule containing 200 mg ebselen that has shown safety and efficacy in several Phase 2 clinical trials involving multiple hearing loss and tinnitus indications including MD. STOPMD-3 enrolled adult subjects (N=221) with a history of definite MD and active symptoms into a randomized double-blind placebo-controlled trial (RCT) in which subjects received 28 days of either SPI-1005 (400 mg twice daily) or placebo treatment with monthly follow-up assessments of auditory and vestibular function through 84 days. Compliant patients could immediately enter an open label extension (OLE) of SPI-1005 treatment for up to 12 months. During OLE, subjects continued to receive SPI-1005 and had their auditory and vestibular function reassessed every 3 months. In both the intent-to-treat and per-protocol RCT analysis, the SPI-1005 group showed higher rates of improvement in low frequency hearing loss (≥10 dB gain at one low frequency from baseline) using pure-tone audiometry (LFPTA) and speech discrimination (≥4-word increase from baseline) using the words-in-noise (WIN) test than the placebo group at day 28, 56, and 84 of follow-up. On day 84, the SPI-1005 group showed a significant rate of LFPTA improvement over placebo (57.9% vs 36.5%, an increase of 58.6% over placebo, p-value=0.0037). When LFPTA criteria were increased to require a ≥10 dB gain at two adjacent low frequencies from baseline, the SPI-1005 group showed a significant rate of improvement of 204.4% over placebo (41.1% vs 13.5%, p-value <0.0001). On day 84, the SPI-1005 group showed a significant rate of WIN improvement of 54.4% over placebo (42.1% vs. 27.1%, p=0.0336). During OLE, responder rates involving LFPTA and WIN continued to improve, and patient reported outcome measures for tinnitus, vertigo, aural fullness, and dizziness severity all improved significantly from baseline (≥30% on average, p-value <0.001). “We would like to thank all of our investigators and study participants for contributing to this pivotal Phase 3 trial success involving SPI-1005,” said Dr. Jonathan Kil, MD, CEO of Sound Pharmaceuticals. A presentation of the full RCT/OLE data analysis as well as additional post-hoc analysis will occur at the Association for Research in Otolaryngology Midwinter Meeting in Orlando FL, February 22-26. About Meniere’s Disease (MD) MD is diagnosed by episodic vertigo or dizziness, fluctuating low frequency hearing loss, and intermittent or constant tinnitus, and is thought to be due to a swelling of the inner ear involving the endolymphatic duct. Patients are typically diagnosed between 40-65 years of age, and the auditory symptoms of hearing loss and tinnitus often involve only one ear. Some patients experience aural fullness or pressure in the affected ear that can also contribute to dizziness. As patients age, the hearing loss and tinnitus become worse resulting in severe to profound hearing loss and intractable tinnitus. For the definite diagnosis of MD, the American Academy of Otolaryngology-Head & Neck Surgery guidance requires audiometric documentation of low frequency hearing loss (i.e., ≥30 dB) in at least one ear using pure tone audiometry. Loss of speech discrimination, especially in noisy environments or when tinnitus is present, is common in MD and other forms of sensorineural hearing loss. MD is currently managed with low salt diets, thiazide diuretics, and oral or locally injected steroids. Unfortunately, this standard of care has not proven effective and is not FDA-approved for the treatment of MD. About the STOPMD-3 trial STOPMD-3 screened 254 participants for eligibility at 11 sites, including some of the leading academic centers in the US. Eligible participants (221) were randomized to either SPI-1005 treatment (400 mg twice daily for 28 days) or matching placebo treatment and followed up to day 84. 201 participants continued on to SPI-1005 OLE for 1-6-months (153 completed) and 107 participants continued on to 7-12-months (82 completed). To our knowledge, STOPMD-3 is the longest continuous treatment trial involving an investigational new drug ever completed for a hearing loss or tinnitus indication including MD. STOPMD-3 was led by Dr. Paul Lambert, Distinguished University Professor and Chair Emeritus of the Dept. of Otolaryngology-HNS at MUSC in Charleston, SC, and the past President of the American Neurotologic Society. Dr. Lambert, Dr. Shaun Nguyen, director of clinical trial research in the Dept. of Otolaryngology-HNS at MUSC, and their colleagues also led the successful Phase 2b RCT involving SPI-1005 and MD patients. About SPI-1005 SPI-1005 is an investigational new drug that contains ebselen, a new chemical entity. Ebselen is a selenorganic compound that mimics and induces glutathione peroxidase (GPx) activity and is effective in reducing neuroinflammation across the central and peripheral nervous system. GPx activity is critical to several cell types and tissues in the inner ear, retina, prefrontal cortex of brain, lung, and kidney, and is often reduced during exposures to environmental insults or aging. Loss of GPx activity has been shown to result in sensorineural hearing loss in multiple animal models. SPI-1005 is being developed for several neurotologic indications including noise-induced hearing loss and two types of ototoxicity (hearing loss, tinnitus, dizziness, or vertigo) caused by aminoglycoside antibiotics (such as tobramycin or amikacin) or platinum-based chemotherapy (such as cisplatin or carboplatin). To date, no significant drug-drug interactions have been observed across multiple study populations including bipolar mania and treatment-resistant depression. About Sound Pharmaceuticals A privately-held biotechnology company is testing SPI-1005 under five other active Investigational New Drug Applications involving several neurotologic indications including the prevention and treatment of aminoglycoside-induced ototoxicity co-funded by the CF Foundation and hearing preservation in cochlear implant patients co-funded by MED-EL.

Microbix Assisting EMQN with Novel Genetic-Test EQA Program

For Rapid Identification of Patients Susceptible to Antibiotic-Induced Hearing LossMISSISSAUGA, Ontario and MANCHESTER, United Kingdom, Dec. 10, 2024 (GLOBE NEWSWIRE) -- Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, and EMQN CIC (EMQN), a global supplier of laboratory external quality assessment (“EQA”) schemes for human genomic testing, announce the go-live of a program to support the accurate identification of patients who carry a gene-variant associated with increased susceptibility to hearing loss following treatment with a widely-used class of antibiotics. This first-of-its kind EQA program is intended to help ensure the proficiency of Point-of-Care Testing (“POCT”) and acute-care labs that are assessing whether patients carry the MT-RNR1 m.1555A>G gene variant. It is estimated that one in 500 persons carry this variant that can lead to profound and irreversible hearing loss upon exposure to aminoglycoside antibiotics. This class of antibiotics include Gentamycin, Kanamycin, Streptomycin, and Tobramycin, which are used to treat a wide range of “gram negative” bacterial infections. Of particular concern are newborn babies who are suspected to be at risk of bacterial sepsis – a life-threatening condition that can lead to death from multi-organ failure if not treated promptly with appropriate antibiotic drugs and other acute medical care. Microbix-produced quality assessment products (“QAPs™”), formatted onto Copan® FLOQSwabs®, are being used in this EMQN EQA program to help assess the proficiency and accuracy of such acute care genetic testing. The QAPs provide samples that participants can process like cheek or buccal swabs, enabling them to verify the accuracy of MT-RNR1 assays in their POCT. With a subscription to this EMQN program, participants will receive three samples every two months (18 per year), helping them to ensure the accuracy of their testing on an ongoing basis and thereby make the most reliable diagnoses possible. Sean Sales, Operations Director at EMQN, commented, “It has been a pleasure to have Microbix’s assistance in making the QAPs for this groundbreaking and important new EQA program. Acute care physicians need the information to be able to evaluate the risk-benefit of antibiotic treatments and no patient should have to face a lifetime of hearing loss when tests to identify this risk are available.” Cameron Groome, CEO and President at Microbix also commented, “We’re pleased to help enable the creation of EQA for this clinically-important decision-making. Our expertise was joined to that of EMQN and Copan to ensure that accurate testing and properly-directed treatment is available for patients worldwide. This QAP marks Microbix’s entry into supporting the accuracy of genetic tests, adding to our established presence in infectious diseases and emerging role in oncology.” UK and international labs can enroll in this EQA program (code POCT MT-RNR1 25) via EMQN CIC at https://www.emqn.org/our-eqa-schemes/ and enquiries about Microbix QAPs can be directed to customer.service@microbix.com.

Osteal Therapeutics Announces Positive 12-Month Results from the APEX Clinical Trial Program at the 2024 American Association of Hip and Knee Surgeons (AAHKS) Annual Meeting

Outcomes at 12 months demonstrate a statistically significant net treatment effect of 19% compared to the standard of care two-stage exchange arthroplasty and highlight a 71% reduction in PJI burdenDALLAS, Nov. 14, 2024 (GLOBE NEWSWIRE) -- Osteal Therapeutics, Inc. (“Osteal”), a clinical-stage biopharmaceutical company developing a new category of combination drug/device therapies for orthopedic infections, announced positive 12-month results from the two APEX (Abbreviated Protocol for Two Stage Exchange) clinical trials of VT-X7 KIT (vancomycin hydrochloride for irrigation; tobramycin sulfate for irrigation/irrigation system) (“VT-X7”) in patients with periprosthetic joint infections (“PJI”) of the hip or knee. The two prospective, randomized, comparative studies evaluated the efficacy of a rapid (7-day) exchange arthroplasty with intra-articular antibiotic irrigation versus the current standard of care, two-stage exchange arthroplasty. Results were featured at the 2024 American Association of Hip and Knee Surgeons (AAHKS) annual meeting and were presented by Dr. Nicolas S. Piuzzi, MD, of the Cleveland Clinic Foundation in Cleveland, Ohio. The APEX clinical program enrolled 152 patients across 23 centers in the U.S., with 76 patients treated in each study arm. Results demonstrated a statistically significant net treatment effect at 12-months of 19% (MSIS Tier 1, VT-X7: 71% vs. Control: 52%). Additionally, the median time to revision arthroplasty was significantly shorter at 7 days in VT-X7 patients compared to 98 days in patients with standard two-stage exchange. Of those patients completing revision arthroplasty (VT-X7: 100% vs. Control: 82%), patients treated with VT-X7 had a shorter overall procedure time by 62 minutes compared to patients treated with two-stage exchange. When considering the overall burden of PJI to the patients during the study follow-up period (i.e. time spent without a permanent implant and/or time spent as a failure), VT-X7 reduced PJI burden by 71% compared to standard two-stage exchange. Overall, the 12-month results demonstrated both a statistically significant and clinically meaningful treatment effect with VT-X7 compared to standard two-stage exchange. “A periprosthetic joint infection presents a significant challenge, with treatment often requiring multiple surgeries and prolonged rounds of antibiotics, which can profoundly disrupt a patient’s life. The APEX clinical program results are impressive, demonstrating a clinical advantage of rapid exchange arthroplasty with target site irrigation and providing surgeons with a promising, transformative approach to treating PJI, one that addresses the need to expedite infection eradication and allow patients to reclaim their lives.” says Dr. Piuzzi, Principal Investigator for the APEX-2 clinical study. About Periprosthetic Joint Infection (PJI) Affecting over 40,000 people in the U.S. annually, PJI is a rare and potentially devastating complication of joint replacement surgery in which pathogenic bacteria colonize the joint prosthesis, forming difficult-to-remove structures called biofilms. Biofilm infections are challenging to resolve, requiring long, invasive and expensive treatments that are often unsuccessful, resulting in high rates of permanent disability and early death. Recent retrospective analyses demonstrate that the current gold standard for treatment of PJI, two-stage exchange arthroplasty, takes an average of 16 weeks and has a success rate under 50% after 12 months, highlighting the unmet need for faster and more efficacious treatment options. About VT-X7 KIT VT-X7 KIT (vancomycin hydrochloride and tobramycin sulfate for irrigation/irrigation system) (“VT-X7”) is a novel drug/device combination product designed to deliver therapeutic concentrations of vancomycin and tobramycin, two well-established, broad-spectrum antibiotics, directly to the joint space and surrounding tissue to treat PJI. VT-X7 is a 7-day therapy designed to address the unmet clinical need for a rapid, reliable treatment for these challenging infections. In clinical studies of VT-X7, 100% of patients were treated and received a new permanent joint prosthesis in seven days with >90% remaining infection-free after one year. The US Food and Drug Administration has granted VT-X7 Breakthrough Therapy, Orphan Drug, Fast Track and Qualified Infectious Disease Product designations. This initial application of VT-X7 represents a first-of-its-kind, multibillion-dollar opportunity to dramatically improve outcomes for a serious unmet medical need in PJI. About Osteal Therapeutics, Inc. Osteal Therapeutics is a privately held, clinical-stage biopharmaceutical company developing novel musculoskeletal therapeutics to treat orthopedic infections and their consequences. The company is leveraging the ability of concentrated, locally delivered antimicrobials to treat the bacterial biofilms typically responsible for musculoskeletal infections while minimizing off-target tissue exposure and associated adverse effects. Osteal employs a low-risk development strategy by using approved drugs with long histories of safety and efficacy as candidates for new routes of local delivery. The company’s lead candidate, VT-X7 KIT, is in late-stage clinical development to treat periprosthetic joint infections, a serious complication of joint replacement surgery.
