Homeopathic Ankle Dislocation for Treatment of Unstable Trimalleolar Fractures Involving Posterior Die-Punch Fragment: A Retrospective Cohort Study.

OBJECTIVES: Unstable trimalleolar fractures are relatively complex and more difficult to manage if die-punch fracture is present. We aimed to evaluate the curative effect of homeopathic ankle dislocation on the unstable trimalleolar fractures involving posterior die-punch fragments. METHODS: A total of 124 patients diagnosed with unstable trimalleolar fractures combined with post-die punch fragment between June 2008 and June 2020 were retrospectively included. Patients who received homeopathic ankle dislocation were named as the experimental group, and patients who accepted conventional treatment were control group. The fracture healing time, wound healing, American Orthopedic Foot and Ankle Society ankle-hindfoot scale (AOFAS), visual analogue scale (VAS), the Kellgren-Lawrence arthritis grading scale (KLAGS) and short-form 36 score (SF-36) scores were collected. Student t-test was used for fracture healing time. Wound healing and SF-36 were compared using the Mann-Whitney test. Repeated measurement analysis of variance (ANOVA) was used for AOFAS and VAS. χ2-test was used for KLAGS. RESULTS: AOFAS showed statistically significant differences between the two groups (p = 0.001). In non-weight-bearing and weight-bearing conditions, VAS scores were significant different between the two groups, and there was an interaction between group and time point (p < 0.001). The experimental group was superior to the control group in terms of physical function (p = 0.022), role-physical (p = 0.018), general health (p = 0.001) and social function (p = 0.042).The operation time of experimental group was shorter than that of control group (p < 0.001). CONCLUSION: Homeopathic ankle dislocation is used for the unstable trimalleolar fractures involving posterior die-punch fragment, which can provide better functional outcomes while shortening the operation time and recovery period.

Efficacy of Individualized Homeopathic Medicines in the Treatment of Sciatica Pain: Double-Blind, Randomized, Placebo-Controlled Trial.

Objectives: Sciatica is a debilitating condition that causes pain in its distribution or in the lumbosacral nerve root that is connected to it. Although there are claims that homeopathy can reduce sciatica pain, systematic scientific proof is currently lacking. The objective of the trial was to determine whether individualized homeopathic medicines (IHMs) were as effective as identical-looking placebos in treating sciatica pain. Design: This is a double-blind, randomized (1:1), two parallel arms, placebo-controlled trial. Setting: The study was conducted at Mahesh Bhattacharyya Homoeopathic Medical College and Hospital, Howrah, West Bengal, India. Subjects: Sixty participants with sciatica pain were included in this study. Interventions: Verum (n = 30; IHMs plus concomitant care) versus control (n = 30; placebos plus concomitant care). Outcome measures: Primary-Sciatica Bothersome Index (SBI) and Sciatica Frequency Index (SFI) scores and secondary-Roland Morris Pain and Disability Questionnaire (RMPDQ), Short Form McGill Pain Questionnaire (SF-MPQ), and Oswestry Low Back Pain Questionnaire (OLBPQ) scores: all of them were measured at baseline, and every month, up to 3 months. Results: Intention-to-treat sample (n = 60) was analyzed. Group differences were examined by two-way (split-half) repeated measure analysis of variance, primarily accounting for between groups and time interactions, and additionally, by unpaired t tests comparing the estimates obtained individually every month. The level of significance was set at p < 0.025 and <0.05 two tailed for the primary and secondary outcomes, respectively. Group differences could not achieve significance in SBI (p = 0.044), SFI (p = 0.080), and RMPDQ scores (p = 0.134), but were significant for SF-MPQ (p = 0.007) and OLBPQ (p = 0.036). Gnaphalium polycephalum (n = 6; 10%) was the most frequently prescribed medicine. No harm, serious adverse events, or intercurrent illnesses were recorded in either of the groups. Conclusions: The primary outcome failed to demonstrate evidently that homeopathy was effective beyond placebo, and the trial remained inconclusive. Independent replications are warranted to confirm the findings. Clinical Trial Registration Number: CTRI/2020/10/028617.

The Three Powerful Traditions of Thinking that Constitute Homeopathy.

By means of a historical, classical philological and philosophical approach, this paper attempts to demonstrate that homeopathy is based on three powerful traditions of thinking, which can be traced back to Ancient Greece's pre-Socratic era. Actually, it seems to be constituted by what may be termed lógos-, hómoion- and iásthai-thinking: that is, thinking in terms of rationality, similarity and healing. By contrast, modern medicine tends to be aligned with just one of these traditions, at the expense of the others, this being not without risk and adverse effects. It is mainly determined by the first type of rationality that genealogically derives from, and is therefore compatible with, the logic of economics whose predominance in the health care systems of modern societies is progressively rising. Homeopathy, however, may not be sufficiently and fairly understood without taking into account the complementary forms of thinking on which it also rests, such as the principle of similarity in an all-encompassing sense, and ancient healing knowledge in the tradition of catharsis. As a corollary of being essentially constituted by the three, homeopathy may persistently be in need of a dynamic equilibrium of its three constituent bases. Attempts to approach homeopathy from only one of the indicated modes of thinking fail to grasp its essence and result in figments or caricatures of what homeopathy was originally meant to be.

HRI London 2023: The Homeopathy Research Community Reunites after a 4-Year Hiatus, Sparking Fresh Collaborations between Researchers 'Old and New'.

The Homeopathy Research Institute's (HRI) 5th international research conference took place in the heart of London, from 16th to 18th June 2023. With 230 attendees from 27 countries, HRI's conferences remain truly international. HRI London 2023 will be remembered for its inspiring blend of 'old and new', with a programme notable for the maturity of the evidence presented by experienced names drawing on decades of work, as well as the enthusiasm and skill of up-and-coming researchers who took the floor to present their new findings. In this report, we present scientific highlights from the event.

Homeopathy-A lively relic of the prescientific era.

Homeopathy was first postulated by the German physician Samuel Hahnemann in 1796 and 220 years later homeopathy is the most popular and widespread alternative medicine. Partly, it is also part of the national healthcare and insurance systems but homeopathy is not without controversy within the medical and healthcare community. Its implausible basic assumptions, some of which contradict natural laws, do not lead us to expect that its remedies have any specific effect. In fact, there is no study or systematic review to date that reliably certifies homeopathy to have an effect beyond the placebo effect and other context effects. In this respect it must be disconcerting how widely homeopathy is applied and represented in therapeutic practice. It indeed claims a role within scientific (evidence-based) medicine but cannot substantiate this claim. It displays clear characteristics of pseudoscience [1]. This implies a lot of problems, such as misleading people and tackling medical ethics up to scientific publication practices. Furthermore, it turns out that quite a few people do not know exactly what homeopathy is, which may lead them to make wrong decisions for their personal health. This article summarizes the information about homeopathy and its problematic implications and serves as a general introduction to this topic and its unacceptable role in today's medicine.The medical irrelevance of the sham method of homeopathy has been proven with more than sufficient probability [2]. As a major testimonial, the statement "Homeopathic products and practices" of the European (EASAC 2017) can be regarded. The primary aim of this brief report is therefore not to take another look at homeopathy from a medical scientific perspective, but rather focus attention on the implications of the still continuous and largely uncritically accepted existence of this method in medical practice, in the medical scientific sphere and in the judgement of the general public.

A Double-Blind, Randomized, Placebo-Controlled Clinical Trial to Evaluate the Efficacy of Individualized Homeopathic Medicines in Pre-diabetes.

BACKGROUND: Pre-diabetes (PD) contributes importantly to the disease burden worldwide and is a precursor to stroke, cardiovascular diseases, as well as type-2 diabetes mellitus. OBJECTIVE: In this project, the efficacy of individualized homeopathic medicines (IHMs) was explored against placebos in the treatment of PD. METHODS: A 6-month, double-blind, randomized, placebo-controlled trial was conducted at the outpatient departments of a homeopathic medical college and hospital in India. Sixty participants with PD were randomized to receive either IHMs (n = 30) or identical-looking placebos (n = 30). Concomitant care measures were advised to both groups of participants in terms of dietary advice, yoga, meditation and exercise. The primary outcome measures were fasting blood sugar (FBS) and the oral glucose tolerance test (OGTT); the secondary outcome was the Diabetes Symptom Checklist-Revised (DSC-R) score. All the outcomes were measured at baseline and after 3 and 6 months of treatment. Inter-group differences and effect sizes (Cohen's d) were calculated using two-way repeated measures analysis of variance models after adjusting baseline differences using analysis of co-variance on the intention-to-treat data. RESULTS: Between-group differences for FBS were statistically significant, favoring IHMs against placebos (F 1,58 = 7.798, p = 0.007), but not for OGTT (F 1,58 = 1.691, p = 0.199). The secondary outcome, DSC-R total score, favoring IHMs significantly compared with placebos (F 1,58 = 15.752, p < 0.001). Calcarea Carbonicum, Thuja occidentalis and Sulphur were the most frequently prescribed medicines. No harm or serious adverse events were recorded from either of the participant groups. CONCLUSION: IHMs produced significantly better results than placebos in FBS and in DSC-R scores but not in OGTT. Independent replications with larger sample sizes are warranted to substantiate the findings. TRIAL REGISTRATION: CTRI/2019/10/021711.

Antiviral Activity of Cinchona officinalis, a Homeopathic Medicine, against COVID-19.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a potentially fatal disease caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Several studies have shown that hydroxychloroquine (HCQ) significantly inhibits SARS-CoV-2 infections in vitro. OBJECTIVE: Since the phytoconstituents of Cinchona officinalis (CO) are similar to those of HCQ, the objective of this study was to test the antiviral potential of different homeopathic formulations of CO. METHODS: An analysis of the molecular composition of CO was carried out using ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry, followed by a detailed docking study. The constituents of CO were docked against various targets of SARS-CoV-2, and the binding potential of the phytoconstituents was compared and quantified. The ligand with the lowest Glide docking score is considered to have the best binding affinity. The cytotoxicity of several homeopathic formulations, including CO mother tincture (CO-MT), was also checked on VeroE6 cells. A known antiviral, remdesivir, was used as a positive control for the in vitro assays to evaluate the effects of CO-MT against SARS-CoV-2-infected VeroE6 cells. RESULTS: Molecular docking studies showed that constituents of CO exhibited binding potential to various targets of SARS-CoV-2, including Mpro, PLpro, RdRp, nucleocapsid protein, ACE2 (in host) and spike protein. Quinoline, one of the constituents of CO, can potentially bind the spike protein of SARS-CoV-2. Quinic acid showed better binding capabilities with Mpro, PLpro RdRp, nucleocapsid protein and ACE2 (allosteric site) than other constituents. Quinidine exhibited better binding to ACE2. Compared to HCQ, other phytoconstituents of CO had the equivalent potential to bind the RNA-dependent RNA polymerase, nucleocapsid protein, Mpro, PLpro and spike protein of SARS-CoV-2. In vitro assays showed that homeopathic CO-MT was not cytotoxic and that CO-MT and remdesivir respectively caused 89% and 99% inhibition of SARS-CoV-2 infection in VeroE6 cells. CONCLUSION: Based on this in silico and in vitro evidence, we propose CO-MT as a promising antiviral medicine candidate for treating COVID-19. In vivo investigation is required to clarify the therapeutic potential of CO-MT in COVID-19.

Overview and quality assessment of health economic evaluations for homeopathic therapy: an updated systematic review.

INTRODUCTION: Likewise other medical interventions, economic evaluations of homeopathy contribute to the evidence base of therapeutic concepts and are needed for socioeconomic decision-making. A 2013 review was updated and extended to gain a current overview. METHODS: A systematic literature search of the terms 'cost' and 'homeopathy' from January 2012 to July 2022 was performed in electronic databases. Two independent reviewers checked records, extracted data, and assessed study quality using the Consensus on Health Economic Criteria (CHEC) list. RESULTS: Six studies were added to 15 from the previous review. Synthesizing both health outcomes and costs showed homeopathic treatment being at least equally effective for less or similar costs than control in 14 of 21 studies. Three found improved outcomes at higher costs, two of which showed cost-effectiveness for homeopathy by incremental analysis. One found similar results and three similar outcomes at higher costs for homeopathy. CHEC values ranged between two and 16, with studies before 2009 having lower values (Mean ± SD: 6.7 ± 3.4) than newer studies (9.4 ± 4.3). CONCLUSION: Although results of the CHEC assessment show a positive chronological development, the favorable cost-effectiveness of homeopathic treatments seen in a small number of high-quality studies is undercut by too many examples of methodologically poor research.

To help make decisions about homeopathy in healthcare, it is important, as with other medical treatments, to look at whether this treatment is effective in relation to its costs; in other words, to see if it is cost-effective. The aim of the current work was to update the picture of scientific studies available on this topic until 2012. To this purpose, two different researchers screened electronic literature databases for studies between January 2012 and July 2022 which assessed both the costs and the effects of a homeopathic treatment. They did this according to strict rules to make sure that no important study was missed. They reviewed the search results, gathered information from the studies, and assessed the quality of the studies using a set of criteria. They detected six additional new studies to the 15 already known from the previous work. Overall, they found that in 14 out of 21 studies, homeopathic treatment was at least equally effective for less or similar costs. For the remaining seven studies, costs were equal or higher for homeopathy. Of these seven, two were shown to be advantageous for homeopathy: indeed, specific economic analyses demonstrated that the benefit of the homeopathic treatment compensated for the higher costs. For the remaining five studies, the higher or equal costs of homeopathic treatment were not compensated by a better effect. The quality of the studies varied, with older studies generally being of lower quality compared to newer ones. The authors concluded that although the quality of research on homeopathy's cost-effectiveness has improved over time, and some high-quality studies show that it can be a cost-effective option, there are still many poorly conducted studies which make it difficult to offer a definitive statement. In other words, while there is some evidence that homeopathy can be effective in relation to its costs, there are still many studies that are not very reliable, which means that interested parties need to be cautious about drawing conclusions.

A Fundamental Question for Complementary Medicine: Are There Other Forces in the Natural World Besides the Physical Forces?

BACKGROUND: The integration of conventional and complementary medicine reflects the pluralism in science. Still, a critical issue is the conception of the natural world. Many complementary therapy systems seem to contradict the reductionist-atomistic paradigm that all of natural reality is essentially based on the physical interactions of atoms and molecules. Thus, a fundamental question about the natural world is: Do other than the physical forces exist? SUMMARY: The assumption that no other than physical forces exist and work in the natural world is not tenable. For example, the formation and maintenance of the functional Gestalt of organisms cannot possibly be explained by molecular processes (e.g., from DNA to RNA and further to amino acids and proteins). The processes on each structural level - from molecules, organelles, cells, organs up to the whole organism - are regulated in regard to the formation of the next higher level. Specific Gestalt-forming forces exist and can be systematically investigated. Their existence implies an extended conception of matter. The Gestalt-forming forces and the extended concept of matter may be relevant for the scientific assessment of complementary therapies. KEY MESSAGES: (i) In the natural world, specific Gestalt-forming forces exist in addition to the physical forces, and can be systematically investigated. (ii) The existence of these forces implies an extended conception of matter. (iii) These forces and this extended concept of matter may be relevant for the scientific assessment of complementary therapies, e.g., homeopathy.In der Integration von konventioneller und komplementärer Medizin spiegelt sich der Methodenpluralismus der Wissenschaft. Die Ontologien vieler komplementärmedizinisches Systeme liegen allerdings außerhalb der Erklärbarkeit durch die Kräfte der Physik. Eine zentrale Frage ist deshalb: Gibt es Kräfte in der Natur, die eine materielle Wirkung haben, deren Ursprung aber nicht in Atomen oder Molekülen und in diesem Sinne nicht in der Materie liegt?Die Annahme, dass in der Natur keine anderen als die mit Atomen und Molekülen assoziierten physikalischen Kräfte existent und wirksam seien, ist wissenschaftlich nicht begründet. Beispielsweise ist die Bildung und Erhaltung der funktionsfähigen Gestalt von Organismen nicht durch molekulare Prozesse (z.B. von der DNA zur RNA und weiter zu Aminosäuren und Proteinen) erklärbar. Die Prozesse auf jeder strukturellen Ebene ­ von den Molekülen, Organellen, Zellen, Organen bis hinauf zum Gesamtorganismus ­ sind in Hinblick auf die Bildung der funktionsfähigen Gestalt der jeweils nächsthöheren Ebene gesteuert. Für diese Gestaltbildung gibt es spezifische Kräfte, die systematisch erforscht werden können. Ihre Existenz impliziert eine erweiterte Konzeption von Materie. Diese Gestalt-bildenden Kräfte und dieses erweiterte Konzept von Materie sind relevant für die wissenschaftliche Erfassung komplementärmedizinischer Systeme.(i) In der Natur sind außer den physikalischen Kräften noch weitere spezifische Kräfte wirksam, beispielsweise bei der Bildung und Erhaltung der funktionsfähigen Gestalt von Organismen. Diese Kräfte können systematisch erforscht werden. (ii) Die Existenz dieser Kräfte impliziert eine erweitere Konzeption von Materie. (iii) Diese Kräfte und das erweiterte Materiekonzept sind relevant für die wissenschaftliche Erfassung komplementärmedizinischer Systeme, beispielsweise der Homöopathie.

Homeopathic Formulations of Syzygium jambolanum Alleviate Glycation-Mediated Structural and Functional Modifications of Albumin: Evaluation through Multi-Spectroscopic and Microscopic Approaches.

BACKGROUND: The growing interest in identifying the mode of action of traditional medicines has strengthened its research. Syzygium jambolanum (Syzyg) is commonly prescribed in homeopathy and is a rich source of phytochemicals. OBJECTIVE: The present study aims to shed light on the anti-glycation molecular mechanism of Syzyg mother tincture (MT), 30c, and 200c on glycated human serum albumin (HSA) by multi-spectroscopic and microscopic approaches. METHODS: The phytochemicals and antioxidant potential of the Syzyg formulations were estimated by the high-performance liquid chromatography and spectroscopic technique, respectively. Glycation was initiated by incubating HSA with methylglyoxal, three Syzyg formulations, and the known inhibitor aminoguanidine in separate tubes at 37°C for 48 hours. The formation of glycation adducts was assessed by spectrofluorometer and affinity chromatography. The structural modifications were analyzed through circular dichroism, Fourier transform infrared spectroscopy, turbidity, 8-anilinonapthalene-1-sulfonic acid fluorescence, and nuclear magnetic resonance. Further, the formation of the aggregates was examined by thioflavin T, native-polyacrylamide gel electrophoresis, and transmission electron microscopy. Additionally, the functional modifications of glycated HSA were determined by esterase-like activity and antioxidant capacity. The binding analysis of Syzyg formulations with glycated HSA was evaluated by surface plasmon resonance (SPR). RESULTS: Syzyg formulations MT, 30c, and 200c contained gallic acid and ellagic acid as major phytochemicals, with concentrations of 16.02, 0.86, and 0.52 µg/mL, and 227.35, 1.35, and 0.84 µg/mL, respectively. Additionally, all three formulations had remarkable radical scavenging ability and could significantly inhibit glycation compared with aminoguanidine. Further, Syzyg formulations inhibited albumin's structural and functional modifications. SPR data showed that Syzyg formulations bind to glycated HSA with an equilibrium dissociation constant of 1.10 nM. CONCLUSION: Syzyg formulations inhibited the glycation process while maintaining the structural and functional integrity of HSA.

Strange, Rare and Peculiar Symptoms of COVID-19 Cases Managed by Practitioners of the Homeopathy Help Network.

BACKGROUND: More than 670 million people have been infected by COVID-19. This case series reports 8 of 55 cases in a broader study of COVID-positive clients who sought homeopathic care for symptoms. Existing studies of homeopathy and COVID-19 have sometimes failed to employ the underpinning theoretical framework of homeopathy-the genus epidemicus. Special focus has been placed on standout symptoms not often reported in conventional medical outlets, known among homeopaths as "strange, rare and peculiar" (SRP) symptoms. The Homeopathy Help Network (HHN) team of practitioners noted SRP symptoms across dozens of cases and studied how they shifted collectively as different variants of the virus emerged. METHODS: COVID-positive individuals self-selected for individualized care for their symptoms using homeopathy. They received tele-health consultations and individualized homeopathy interventions in an out-patient homeopathy clinical setting. Clients were seen by individual professional homeopathy practitioners and students under supervision working at the HHN in the United States. Cases for the series were hand-picked with the aim of being an average representation of the more than 4,000 COVID-positive cases seen by members of the HHN. Cases in the full compendium are grouped according to a predominant case feature: Multiple remedies, Posology, Time ill, Single remedy resolution, Hospitalization and, in this case series, SRP symptoms. RESULTS: SRP symptoms included: continually on the verge of unconsciousness; dark green stools; very low pulse alternating with tachycardia; sensation of strong or burning chemical smells; sensation of inhaling water through the nose; recurring electric shock sensations in head or extremities; yellow-green stools. CONCLUSION: Collective SRP symptoms from the pandemic provided the opportunity to study the hallmark features of COVID-19 in depth. The importance of these symptoms highlights the applicability of Hahnemannian principles and good case-taking practices.

A Randomized Three-Arm Double-Blind Placebo-Controlled Study of Homeopathic Treatment of Children and Youth with Attention-Deficit/Hyperactivity Disorder.

Objectives: Approximately 30% of children diagnosed with attention-deficit/hyperactivity disorder (ADHD), the most prevalent mental health disorder in children worldwide, do not respond to conventional pharmaceutical treatments. Previous studies of homeopathic treatment for ADHD have been inconclusive. The objectives of this study were to determine if there (a) is an overall effect of homeopathic treatment (homeopathic medicines plus consultation) in the treatment of ADHD; (b) are any specific effects the homeopathic consultation alone in the treatment of ADHD; and (c) are any specific effects of homeopathic medicines in the treatment of ADHD. Design: The design was a randomized double-blind placebo-controlled clinical trial. Setting/Location: Toronto, Canada. Subjects: Children aged 6-16 years diagnosed with ADHD. Interventions: Participants were randomized to one of three arms: Arm 1 (Remedy and Consultation); Arm 2 (Placebo and Consultation); or Arm 3 (Usual Care). Outcome Measures: Primary Outcome was the change of CGI-P T score between baseline and 28 weeks. Results: There was an improvement in ADHD symptoms as measured by the Conner 3 Global Index-Parent T-score in the two groups (Arms 1 and 2) that received consultations with a homeopathic practitioner when compared with the usual care control group (Arm 3). Parents of the children in the study who received homeopathic consultations (Arms 1 and 2) also reported greater coping efficacy compared with those receiving usual care (Arm 3). There was no difference in adverse events among the three study arms. Conclusions: In this study, homeopathic consultations provided over 8 months with the use of homeopathic remedy was associated with a decrease in ADHD symptoms in children aging 6-16 years when compared with usual treatment alone. Children treated with homeopathic consultations and placebo experienced a similar decrease in ADHD symptoms; however, this finding did not reach statistical significance when correcting for multiple comparisons. Homeopathic remedies in and of themselves were not associated with any change in ADHD symptoms. Clinical Trial Registration: This trial was registered on ClinicalTrials.gov; NCT02086864.

Acute and Sub-acute Oral Toxicity Assessment of Ferrum phosphoricum in Rats.

BACKGROUND: Ferrum phosphoricum (FP) has been used by traditional medicine practitioners for various ailments since ancient times. However, scientific evidence on the safety of FP is still unavailable. Thus, the current study aimed to investigate the acute and sub-acute oral toxicity of homeopathic FP in experimental rats. METHODS: In an acute toxicity investigation, a single dose of 2,000 µL/kg of FP 6c, 30c and 200c was administered to female Wistar rats, which were monitored for up to 14 days according to the Organization for Economic Cooperation and Development (OECD) guideline 423. For a sub-acute toxicity study, FP 6c, 30c and 200c (200 µL/kg) were administered to male and female rats for 28 days as per the OECD guideline 407. All the animals were observed for mortality, clinical signs and body weight during the study. At the end of the experiment, hematological, biochemical and histopathological assessments were performed. RESULTS: During the acute toxicity study, no mortality was observed in rats administered with FP, and thus the median lethal dose (LD50) was identified as >2,000 µL/kg. In the sub-acute study, no mortality or adverse clinical signs were noticed with FP treatment. Moreover, weekly body weight gain was normal. Hematological and biochemical investigations revealed no abnormalities. Furthermore, histological analysis of FP-treated rats' vital organs revealed no pathological changes. CONCLUSION: Overall, our findings imply that FP 6c, 30c and 200c potencies are safe and do not cause toxicity when given orally to Wistar albino rats for an extended period at a dose of 200 µL/kg.

Aspirin 15cH has Different Effects on Morphology and Function of Lipopolysaccharide-Challenged RAW 264.7 Macrophages In Vitro Compared to a Pharmacological Dose of Aspirin.

INTRODUCTION: Aspirin is one of the most commonly used drugs worldwide. It is known to present antipyretic, anti-inflammatory and anti-thrombotic actions, making it extremely useful in a wide range of clinical contexts. Interestingly, homeopathically prepared Aspirin 15cH has been found to have a pro-thrombotic effect in rats, raising the hypothesis that Aspirin 15cH could also modulate the activity of inflammatory cells in different pathological processes. OBJECTIVE: Our objective was to assess what effect Aspirin 15cH has on RAW 264.7 macrophages in vitro. METHODS: The effects of Aspirin 15cH on biochemical and morphological activities of lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages were evaluated. These effects were compared with unchallenged macrophages (negative control), untreated LPS-stimulated macrophages, macrophages treated with succussed water (vehicle control), or aspirin 200 µg/mL (pharmacological inhibitor of LPS activity). Cell morphology (adhered cell area and cytoskeleton arrangements), cell viability, toll-like receptor-4 (TLR-4) expression, and the production of nitric oxide, cytokines and intracellular reactive oxygen species were assessed. RESULTS: Aspirin 15cH reduced the number of cells expressing TLR-4 on the surface (p = 0.03) and induced a "columnar" morphology of macrophage pseudopods, indicating changes in cytoskeleton arrangement. When cells were treated with both Aspirin 15cH and LPS, cell morphology became heterogeneous, suggesting that sub-populations of cells had differing sensitivities to LPS or Aspirin 15cH. Exposure of the cells to LPS alone, succussed water or aspirin 200 µg/mL produced effects consistent with the literature. CONCLUSION: Aspirin 15cH, aspirin 200 µg/mL, LPS and succussed water appear to act as independent stimuli able to induce different patterns of macrophage response. Aspirin 15cH induced changes suggestive of M2 polarization of the macrophages (i.e., toward a wound healing or tissue repair, rather than inflammatory, phenotype). These preliminary findings need to be confirmed in further specific studies.
