Abstract
Introduction: A significant number of the South African population still rely on traditional medicines (TM) as their primary healthcare due to their belief in their holistic healing and immune-boosting properties. However, little to no scientific data is available on the effects of most TM products on cytokine and cellular biomarkers of the immune response. Here, we evaluated the impact of traditional medicine [Product Nkabinde (PN)] in inducing cellular and cytokine biomarkers of inflammation in peripheral blood mononuclear cells (PBMCs) from eight healthy volunteers. Methods: PN was supplied by a local Traditional Health Practitioner (THP). The IC50 (half maximum concentration) of the standardized extract on isolated PBMCs was established using the cell viability assay over 24 h of incubation. Luminex and flow cytometry assays were used to measure cytokine and cellular levels in PBMCs stimulated with PN and/or PHA over 24, 48, and 72 h, respectively. Results: The IC50 concentration of PN in treated PBMCs was established at 325.3 μg/mL. In the cellular activation assay, the percentages of CD38-HLA-DR + on total CD4+ T cells were significantly increased in PBMCs stimulated with PN compared to unstimulated controls after 24 h (p = 0.008). PN significantly induced the production of anti-inflammatory IL-10 (p = 0.041); proinflammatory cytokines IL-1α (p = 0.003), TNF-α (p < 0.0001); and chemokine MIP-1β (p = 0.046) compared to the unstimulated control after 24 h. At 48 h incubation, the production of proinflammatory cytokines IL-1α (p = 0.034) and TNF-α (p = 0.011) were significantly induced following treatment with PN. Conclusion: We conclude that the PN possesses in vitro immunomodulatory properties that may influence immune and inflammatory responses. More studies using PN are needed to further understand key parameters mediating induction, expression, and regulation of the immune response in the context of pathogen-associated infections.

BMC Complement Med Ther 2024; 24:35. [PMID: 38216975 PMCID: PMC10785464 DOI: 10.1186/s12906-023-04300-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Accepted: 12/07/2023] [Indexed: 01/14/2024] Open
Abstract
The development of antiretroviral therapy has brought a tremendous relief to the world as it minimizes mortality, reduces HIV transmission, and suppresses progression in infected patients. However, the orthodox antiretroviral therapy is faced with limitations which have necessitated a continuous search for more novel plant-based antiviral compounds, which can bypass the existing barriers created by drug resistance and target more viral proteins. Despite the edibility and enormous pharmacological benefits of T. portulacastrum, little is known about its nutrient profiles and potential use as a natural source of antiviral drug. This study focuses on the full feed analysis and anti-HIV potential of two biotypes of T. portulacastrum. Ethanolic extracts of both biotypes of T. portulacastrum (T01 and T02) had significant inhibitory effects on the level of replication of the HIV-1. Both extracts induced the inhibition of at least 50% of the HIV-1 viral load at considerably low IC50 values of 1.757 mg/mL (T01) and 1.205 mg/mL (T02) which is comparable to the AZT standard. The protein composition ranged between 8.63-22.69%; fat (1.84-4.33%); moisture (7.89-9.04%); fibre (23.84-49.98%); and carbohydrate content (38.54-70.14%). Mineral contents of tested T. portulacastrum varied considerably in different parts of the plant. Nitrogen N mineral ranged between 13.8-36.3 mg/g; sodium Na (2.0-14.0 mg/g); potassium K (14.0-82.0 mg/g); magnesium Mg (2.8-7.1 mg/g); calcium Ca (9.1-24.7 mg/g); phosphorus P (1.3-3.6 mg/g); iron Fe (193.5-984.0 ppm); zinc Zn (42.5-96.0 ppm); manganese Mn (28.5-167.5 ppm); and copper Cu (2.0-8.5 ppm). These mineral values are comparable or higher than values quoted for common vegetables, suggesting that T. portulacastrum is a nutrient-dense vegetable that could provide alternative sources of antiviral nutrients to HIV-infected individuals. Further studies are recommended to unravel key metabolites responsible for high nutrient profiles and antiretroviral effects in T. portulacastrum.

Prevalence of advanced HIV disease and associated factors among antiretroviral therapy naïve adults enrolling in care at public health facilities in Kampala, Uganda. Ther Adv Infect Dis 2024; 11:20499361241251936. [PMID: 38770168 PMCID: PMC11103927 DOI: 10.1177/20499361241251936] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 04/15/2024] [Indexed: 05/22/2024] Open
Abstract
Background Despite adoption of the 'test-and-treat' strategy, a high proportion of antiretroviral therapy (ART) naïve people living with HIV (PLHIV) enrol in care with, and die of advanced HIV disease (AHD) in Uganda. In this study, we aimed to determine the prevalence of AHD among ART naïve adults enrolling in care and associated factors at selected public health facilities in Kampala, Uganda. Methods From April to July 2022, we conducted a mixed-methods study at Kiswa Health Centre III, Kitebi Health Centre III, and Kawaala Health Centre IV. The study involved cross-sectional enrolment and evaluation of 581 participants, utilizing an interviewer-administered questionnaire and chart reviews. Modified Poisson regression was employed to identify factors associated with AHD, complemented by a qualitative component comprising fifteen in-depth interviews, with data analysed through thematic analysis. Results Overall, 35.1% (204/581) of the study participants had AHD. Being male [adjusted prevalence ratio (aPR): 1.4, 95% CI: 1.04-1.88] and aged 35-50 years (aPR: 1.81, 95% CI: 1.14-2.88) were associated with AHD. Participants with no personal health perception barriers had 37% lower odds of presenting to care with AHD (aPR: 0.63, 95% CI: 0.46-0.85). Qualitative findings indicated that individual factors, such as waiting until physical health deteriorated and initially opting for alternative therapies, took precedence in contributing to enrolment in care with AHD. Conclusion Over one in every three ART naïve adults presents to public health facilities in Uganda with AHD. Male gender, age 35-50 years, and personal health perception barriers emerged as significant factors associated with AHD; emphasizing the need for targeted interventions to address these disparities and enhance early detection and engagement in care. Routine HIV testing should be emphasized and incentivized especially for men and persons aged 35-50 years.

Abstract
The second most common and lethal disease is lung cancer. To combat the negative effects of today's synthetic medications, natural phytomedicines are required. Tragia plukenetii is a medicinal plant native to India that belongs to the Euphorbiaceae family. The purpose of this research is to isolate bioactive compounds from T. plukenetii leaves and then test them for anticancer property. A single compound (CH: ME-20:80) was separated using TLC, and an RF value of 0.55 was determined. Spectral analyses utilizing UV-Visible Spectrophotometer and FT-IR were used to examine the absorbance and functional groups. 13C-NMR and 1H-NMR studies revealed the tentative name of the purified phytochemical as omega-decenol (OD). Further antioxidant and anticancer properties of OD were tested for in vitro. In comparison to conventional L-ascorbic acid, the DPPH radical scavenging assay experiment yielded an IC50 of 147.48 g/ml. With an IC50 value of 24 µg/ml (Omega-decenol) and 32 µg/ml (doxorubicin), the MTT assay demonstrated the cytotoxic capability against the A549 lung cancer cell line. FACS revealed the cell cycle arrest of A549 at S phase compared to control with the high-dose IC50 (250 µg/ml) of omega-decenol. Twelve major compounds were detected in the active fraction using GC-MS analysis, where n-hexadecanoic acid was found as a major. Omega-decenol showed good binding affinity against EGFR, amongst other receptors in the in silico docking study. This research reveals the potent anticancer activity of the isolated compound omega-decenol from T. plukenetii leaves and provides a key path to understanding the molecular interaction in anticancer aspects against adenocarcinoma.

Abstract
Natural products have been considered a potential resource for the development of novel therapeutic agents, since time immemorial. It is an opportunity to discover cost-effective and safe drugs at the earliest, with the goal to hit specific targets in the HIV life cycle. Natural products with inhibitory activity against human immunodeficiency virus are terpenes, coumarins, flavonoids, curcumin, proteins, such as lectins, laccases, bromotyrosines, and ribosome-inactivating proteins. Terpenes inhibit virus fusion, lectins and flavonoids have an inhibitory impact on viral binding, curcumin and flavonoids inhibit viral DNA integration. The most important medicinal plants which have been used in traditional Chinese medicinal sciences with anti-HIV properties are Convallaria majalis, Digitalis lanata, Cassia fistula, Croton macrostachyus, Dodonaea angustifolia, Ganoderma lucidum, Trametes versicolor, Coriolus versicolor, Cordyceps sinensis, Gardenia jasminoides, Morus alba, Scutellaria baicalensis, Ophiopogon japonicus, Platycodon grandiflorus, Fritillaria thunbergii, Anemarrhena asphodeloides, Trichosanthes kirilowii, Citrus reticulata, Glycyrrhiza uralensis, Rheum officinale, Poria cocos, Rheum palmatum, Astragalus membranaceus, Morinda citrifolia, Potentilla kleiniana, Artemisia capillaris, Sargassum fusiforme, Piperis longi fructus, Stellera chamaejasme, Curcumae rhizoma, Dalbergia odorifera lignum, Arisaematis Rhizoma preparatum, and Phellodendron amurense. The information provided is gathered from randomized control experiments, review articles, and analytical studies and observations, which are obtained from different literature sources, such as Scopus, Google Scholar, PubMed, and Science Direct from July 2000 to August 2023. The aim of this review article is to survey and introduce important medicinal plants and herbs that have been used for the treatment of HIV, especially the medicinal plants that are common in traditional Chinese medicine, as research to date is limited, and more evidence is required to confirm TCM,s efficacy.

Abstract
Objectives The recent emergence of the COVID-19 pandemic (caused by SARS-CoV-2) and the experience of its unprecedented alarming toll on humanity have shone a fresh spotlight on the weakness of global preparedness for pandemics, significant health inequalities, and the fragility of healthcare systems in certain regions of the world. It is imperative to identify effective drug treatments for COVID-19. Therefore, the objective of this review is to present a unique and contextualised collection of antiviral natural plants or remedies from the West African sub-region as existing or potential treatments for viral infections, including COVID-19, with emphasis on their mechanisms of action. Evidence acquisition Evidence was synthesised from the literature using appropriate keywords as search terms within scientific databases such as Scopus, PubMed, Web of Science and Google Scholar. Results While some vaccines and small-molecule drugs are now available to combat COVID-19, access to these therapeutic entities in many countries is still quite limited. In addition, significant aspects of the symptomatology, pathophysiology and long-term prognosis of the infection yet remain unknown. The existing therapeutic armamentarium, therefore, requires significant expansion. There is evidence that natural products with antiviral effects have been used in successfully managing COVID-19 symptoms and could be developed as anti-COVID-19 agents which act through host- and virus-based molecular targets. Conclusion Natural products could be successfully exploited for treating viral infections/diseases, including COVID-19. Strengthening natural products research capacity in developing countries is, therefore, a key strategy for reducing health inequalities, improving global health, and enhancing preparedness for future pandemics.

Abstract
Due to the absence of successful therapy, vaccines for protection are continuously being developed. Since vaccines must be thoroughly tested, viral respiratory tract infections (VRTIs), mainly coronaviruses, have seriously affected human health worldwide in recent years. In this review, we presented the relevant data which originated from trusted publishers regarding the practical benefits of functional foods (FFs) and their dietary sources, in addition to natural plant products, in viral respiratory and COVID-19 prevention and immune-boosting activities. As a result, FFs were confirmed to be functionally active ingredients for preventing COVID-19 and VRTIs. Furthermore, the antiviral activity and immunological effects of FFs against VRTIs and COVID-19 and their potential main mechanisms of action are also being reviewed. Therefore, to prevent COVID-19 and VRTIs, it is critical to identify controlling the activities and immune-enhancing functional food constituents as early as possible. We further aimed to summarize functional food constituents as a dietary supplement that aids in immune system boosting and may effectively reduce VRTIs and COVID-19 and promote therapeutic efficacy.

Abstract
Introduction: Many people living with HIV/AIDS (PLHIV) in Uganda widely use herbal medicines. However, their toxicity and safety have not been investigated. The use of these plants can potentially cause harmful effects to the health of patients. The purpose of this study was to determine the cytotoxicity of some commonly used medicinal plant species used by PLHIV. Methods: The cytotoxicity of the plant extracts was determined with the AlamarBlue cell viability assay using the human glioblastoma cell line U87.CD4.CXCR4. The cells were treated with varying concentrations of extracts of Warburgia ugandensis, Erythrina abyssinica, Cryptolepis sanguinolenta, Albizia coriaria, Psorospermum febrifugium, Gymnosporia senegalensis, Zanthoxylum chalybeum, Securidaca longipendunculata, Vachellia hockii, Gardenia ternifolia, and Bridelia micrantha reconstituted with ethanol and dimethyl sulfoxide (DMSO). Using regression analysis, the half maximal cytotoxic concentration (CC50) of the plant extracts were calculated from exponential curve fits, since they provided the highest coefficient of determination, R2. Results: The ethanol extracts of W. ugandensis (CC50 = 7.6 μg/ml) and A. coriaria (CC50 = 1.5 μg/ml) as well as the DMSO-reconstituted extracts of W. ugandensis (CC50 = 6.4 μg/ml) and A. coriria (CC50 = < 4 μg/ml) were highly cytotoxic. The cytotoxicity of W. ugandensis and A. coriaria compared well with the indigenous traditional knowledge of the toxic effects experienced when the plants were not used correctly. However, the cytotoxicity of most of the plant extracts (15/22) was low to moderate (CC50 = 21–200 μg/ml). Conclusion: Most of the plant species tested in this study had low to moderate cytotoxicity against U87.CD4.CXCR4 cells, except W. ugandensis and A. coriria which were highly cytotoxic.

Abstract
Introduction: The worldwide burden of viral infections has triggered a resurgence in the search for new and more efficient antiviral drugs. Scientists are also repurposing existing natural compounds such as the antimalarial drug artemisinin from Artemesia annua L. as potential drug candidates for some of the emerging and re-emerging viral infections such as covid-19 Aim: The aim of this review was to analyse the existing literature to explore the actual or potential natural antiviral compounds from African and Asian medicinal plants as lead compounds in the drug discovery process. Methods: We searched the literature on African and Asian medicinal plant species as antiviral agents for HIV-1 and the novel coronavirus (SARS-CoV-2) in various databases and search engines such as Web of Science, Google Scholar and PubMed. The search was limited to in vitro, in vivo, and clinical studies and excluded in silico studies. Results: We present 16 plant species with actual or potential antiviral activity against HIV-1 and SARS-CoV-2. These plant species span the continents of Africa and Asia where they are widely used for treating several other ailments. Conclusion: Natural compounds from plants can play a significant role in the clinical management of HIV/AIDS and the covid-19 pandemic. More research needs to be conducted to investigate the potential toxicities of the various compounds and their efficacies in clinical settings.

Abstract
Introduction: Despite concerns about toxicity, potentially harmful effects and herb-drug interactions, the use of herbal medicines remains widely practiced by people living with HIV/AIDS (PLHIV) in Uganda. Objective: The objective of the paper was to comprehensively review the literature on the toxicity and chemical composition of commonly used medicinal plant species in treating PLHIV in Uganda. Methods: We reviewed relevant articles and books published over the last sixty years on ethnobotany, antiviral/anti-HIV activity, toxicity, phytochemistry of Vachellia hockii, Albizia coriaria, Bridelia micrantha, Cryptolepis sanguinolenta, Erythrina abyssinica, Gardenia ternifolia, Gymnosporia senegalensis, Psorospermum febrifugium, Securidaca longipendunculata, Warburgia ugandensis and Zanthoxylum chalybeum and their synonyms. We searched PubMed, Web of Science, Scopus, Science Direct and Google Scholar. Discussion: Most of the plant species reviewed apart from P. febrifugium, S. longipedunculata and C. sanguinolenta lacked detailed phytochemical analyses as well as the quantification and characterization of their constituents. Crude plant extracts were the most commonly used. However, purified/single component extracts from different plant parts were also used in some studies. The U87 human glioblastoma was the most commonly used cell line. Water, ethanol, methanol and DMSO were the commonest solvents used. In some instances, isolated purified compounds/extracts such as Cryptolepine and Psorospermin were used. Conclusion: Cytotoxicity varied with cell type, solvent and extract type used making it difficult for direct comparison of the plant species. Five of the eleven plant species namely, A. coriaria, C. sanguinolenta, G. ternifolia, P. febrifugium and Z. chalybeum had no cytotoxicity studies in animal models. For the remaining six plant species, the crude aqueous and ethanol extracts were mainly used in acute oral toxicity studies in mice. Herbalists reported only A. coriaria and W. ugandensis to cause toxic side effects in humans. However, selective cytotoxic plant extracts can potentially be beneficial as anticancer or anti-tumour drugs.

Khadka D, Dhamala MK, Li F, Aryal PC, Magar PR, Bhatta S, Thakur MS, Basnet A, Cui D, Shi S. The use of medicinal plants to prevent COVID-19 in Nepal. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2021; 17:26. [PMID: 33832492 PMCID: PMC8027983 DOI: 10.1186/s13002-021-00449-w] [Citation(s) in RCA: 51] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Accepted: 03/10/2021] [Indexed: 05/05/2023]
Abstract
BACKGROUND Medicinal plants are the fundamental unit of traditional medicine system in Nepal. Nepalese people are rich in traditional medicine especially in folk medicine (ethnomedicine), and this system is gaining much attention after 1995. The use of medicinal plants has increased during the COVID-19 pandemic as a private behavior (not under the control of government). A lot of misinterpretations of the use of medicinal plants to treat or prevent COVID-19 have been spreading throughout Nepal which need to be managed proactively. In this context, a research was needed to document medicinal plants used, their priority of use in society, their cultivation status, and the source of information people follow to use them. This study aimed to document the present status of medicinal plant use and make important suggestion to the concerned authorities. METHODS This study used a web-based survey to collect primary data related to medicinal plants used during COVID-19. A total of 774 respondents took part in the survey. The study calculated the relative frequencies of citation (RFC) for the recorded medicinal plants. The relationship between plants recorded and different covariates (age, gender education, occupation, living place, and treatment methods) was assessed using Kruskal-Wallis test and Wilcoxon test. The relationship between the information sources people follow and the respondent characteristics was assessed using chi-square test. RESULTS The study found that the use of medicinal plants has increased during COVID-19 and most of the respondents recommended medicinal plants to prevent COVID-19. This study recorded a total of 60 plants belonging to 36 families. The leaves of the plants were the most frequently used. The Zingiber officinale was the most cited species with the frequency of citation 0.398. Most of the people (45.61%) were getting medicinal plants from their home garden. The medicinal plants recorded were significantly associated with the education level, location of home, primary treatment mode, gender, and age class. The information source of plants was significantly associated with the education, gender, method of treatment, occupation, living with family, and location of home during the lockdown caused by COVID-19. CONCLUSIONS People were using more medicinal plants during COVID-19 claiming that they can prevent or cure COVID-19. This should be taken seriously by concerned authorities. The authorities should test the validity of these medicinal plants and control the flow of false information spread through research and awareness programs.

[PMID: 33462562 PMCID: PMC7806454 DOI: 10.1016/j.heliyon.2021.e05957] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 07/24/2020] [Accepted: 01/08/2021] [Indexed: 12/30/2022] Open
Abstract
Background Viruses are responsible for several diseases, including severe acute respiratory syndrome, a condition caused by today's pandemic coronavirus disease (COVID-19). A negotiated immune system is a common risk factor for all viral infections, including COVID-19. To date, no specific therapies or vaccines have been approved for coronavirus. In these circumstances, antiviral and immune boosting foods may ensure protection against viral infections, especially SARS-CoV-2 by reducing risk and ensuring fast healing of SARS-CoV-2 illness. Scope and approach In this review, we have conducted an online search using several search engines (Google Scholar, PubMed, Web of Science and Science Direct) to find out some traditional foods (plant, animal and fungi species), which have antiviral and immune-boosting properties against numerous viral infections, particularly coronaviruses (CoVs) and others RNA-virus infections. Our review indicated some foods to be considered as potential immune enhancers, which may help individuals to overcome viral infections like COVID-19 by modulating immune systems and reducing respiratory problems. Furthermore, this review will provide information regarding biological properties of conventional foods and their ingredients to uphold general health. Key Findings and Conclusions We observed some foods with antiviral and immune-boosting properties, which possess bioactive compounds that showed significant antiviral properties against different viruses, particularly RNA viruses such as CoVs. Interestingly, some antiviral and immune-boosting mechanisms were very much similar to the antiviral drug of COVID-19 homologous SARS (Severe Acute Respiratory Syndrome Coronavirus) and MERS (Middle East Respiratory Syndrome Coronavirus). The transient nature and the devastating spreading capability of COVID-19 lead to ineffectiveness of many curative therapies. Therefore, body shielding and immune-modulating foods, which have previous scientific recognition, have been discussed in this review to discern the efficacy of these foods against viral infections, especially SARS-CoV-2.

Abstract
Novel coronavirus is a family of viruses that usually leads to respiratory illness. This coronavirus pandemic has affected human life drastically, and there is a chance that this virus persists on raw foods of animal origin. Also, food that is served to the customers by retail sectors passes through different operational steps, which involves multiple touchpoints by the food handlers on the surface of the food or to the food directly. This may lead to the spreading of the coronavirus through the food sector if proper hygiene, sanitization, and disinfection, social distancing, and other preventive measures are not followed. This chapter will give an overview of the type of foodborne viruses and their effects on human health. It will also provide an understanding of the possibilities of transmitting coronavirus disease (COVID-19) through food and food packaging. The review will also focus on the preventive measures, hygiene practices, and safety precautions that should be adopted by the food handlers or food business owners to mitigate the risk of transmitting COVID-19 in the food service and retail sector. Essential aspects of the food safety management system with respect to COVID-19 will be discussed, which should be followed by all the food companies. Finally, the role of different dietary supplements and bioactive ingredients of foods and herbs will be discussed that are known to improve the human immune system, which will fight against the virus.

Abstract
Aim: Severe acute respiratory syndrome coronavirus-2 (SARS-COV-2), a pernicious viral disease, causes acute respiratory distress responsible for mortality and morbidity worldwide. To screen different immunomodulatory medicinal compounds to unravel their interaction with SARS-COV-2 viral proteins. Materials & methods: A library of immunomodulatory medicinal compounds with antiviral capability were analyzed against SARS proteases, spike protein and nonstructural proteins (NSP-9, 15) using Autodock vina. Results: Out of more than 300 medicinal compounds, only six compounds: arzanol, ferulic acid, genistein, resveratrol, rosmanol and thymohydroquinone showed significant interaction with the SARS viral proteins by forming hydrogen bonds with the active site residues with low binding energy. Further ADMET (absorption, distribution, metabolism, excretion and toxicity) analysis showed good pharmacokinetic properties and low acute toxicity of these compounds. Conclusion: The current study provides convincing evidence that these medicinal compounds exert antiviral activity against the SARS-COV-2 virus and could be further exploited for the treatment of this disease.
