Chin J Integr Med, 2023 Jan;29(1):69-73.
PMID: 35829957 DOI: 10.1007/s11655-022-3519-y

OBJECTIVE: To examine data from studies supporting the clinical efficacy of medical approaches from India traditional systems of medicines like Ayurveda, Unani, Siddha, and Homeopathy for psoriasis using outcome indicators employed in clinical practice and research.
METHODS: Searches were conducted between December 2019 and September 2020 in databases PubMed, Scopus, Web of Science and Ovid Medline using search terms including traditional, complementary, psoriasis, Kushtha, Ayurveda, Siddha, Unani, Homeopathy and clinical. Controlled trials, case series and case reports published from India were included.
RESULTS: Data of 17 selected studies were extracted. Treatment efficacy in terms of improvement in Psoriasis Area and Severity Index (PASI) score or/and percentage reduction in score (PASI 50, PASI 75 and PASI 90) or/and patient-reported outcomes using instruments like Dermatology Life Quality Index and Psoriasis Disability Index were noted. All studies reported good improvement as per the study specific outcome. However, study characteristics, including study design, sample size, follow-up period, inclusion and exclusion criteria were heterogeneous, and the choice of outcome measures was not adequate to conclude the effectiveness of intervention. The use of some herbs as common ingredients in several formulations across different systems of medicines were noted in analyzing individual formulation.
CONCLUSIONS: Future studies must incorporate a comprehensive study design with specific outcome measures like PASI, PASI 75, PASI 90, quality of life parameters, compliance to medications, adverse reactions, remission period, relapse rate and cost-effectiveness with long term follow-up. The currently available evidence on the roles of these herbs at molecular level in psoriasis is preliminary.

Alzheimer's, a progressive neurodegenerative disease affects brain and neurons through enormous reduction in nerve cell regenerative capacity. Dementia and impairment of cognitive functions are more prevalent in Alzheimer's disease (AD) patients in both industrialized and non-industrialized countries. Various factors play significant role in molecular cascades that leads to neuronal inflammation, dementia and thereby AD progression. Current medications are symptomatic that alleviates pain while lack in absolute cure, urging researchers to explore targets and therapeutics. Interestingly, nanomedicines developed due to the onset of nanotechnology, are being extensively investigated for the treatment of AD. This review presents the advancement in nanotherapeutic strategies, involving the emergence of nanomaterials that offers advantage to pass through the blood-brain barrier and acts as a therapeutic modality against AD.

Medical devices, being life-saving tools, are considered to be a boon for healthcare system. However, in addition to their therapeutic effects, there are several ill consequences that are caused by these devices. An effective cohort vigilant system was needed to manage such adverse effects. This had led to the introduction of materiovigilance. Materiovigilance is the study and follow-up of occurrences that arise as a result from the usage of the medical equipment. It not only manages adverse events (AE) but also creates harmonization among countries. Keeping these objectives in focus, the principles, perspectives, and practices with regard to materiovigilance that are followed in the USA, Europe, China, Japan, Australia, Canada, and India are being compared. Such a comparison is essential, which will help us to understand the gaps in the current regulatory systems in the above-mentioned countries and furthermore will provide a comprehensive picture to the regulatory authorities to amend any existing laws if required. These amendments may ensure optimal patient safety by providing them a benign experience from the use of medical devices.

Urinary tract infections (UTIs) are becoming more common, requiring extensive protection from antimicrobials. The global expansion of multi-drug resistance uropathogens in the past decade emphasizes the necessity of newer antibiotic treatments and prevention strategies for UTIs. Medicinal plants have wide therapeutic applications in both the prevention and management of many ailments. Bacopa monnieri is a medicinal plant that is found in the warmer and wetlands regions of the world. It has been used in Ayurvedic systems for centuries. The present study aimed to investigate the antibacterial potential of the extract of B. monnieri leaves and its bioactive molecules against UTIs that are caused by Klebsiella pneumoniae and Proteus mirabilis. This in vitro experimental study was conducted by an agar well diffusion method to evaluate the antimicrobial effect of 80% methanol, 96% ethanol, and aqueous extracts of B. monnieri leaves on uropathogens. Then, further screening of their phytochemicals was carried out using standard methods. To validate the bioactive molecules and the microbe interactions, AutoDock Vina software was used for molecular docking with the Klebsiella pneumoniae fosfomycin resistance protein (5WEW) and the Zn-dependent receptor-binding domain of Proteus mirabilis MR/P fimbrial adhesin MrpH (6Y4F). Toxicity prediction and drug likeness were predicted using ProTox-II and Molinspiration, respectively. A molecular dynamics (MD) simulation was carried out to study the protein ligand complexes. The methanolic leaves extract of B. monnieri revealed a 22.3 mm ± 0.6 mm to 25.0 mm ± 0.5 mm inhibition zone, while ethanolic extract seemed to produce 19.3 mm ± 0.8 mm to 23.0 mm ± 0.4 mm inhibition zones against K. pneumoniae with the use of increasing concentrations. In the case of P. mirabilis activity, the methanolic extracts showed a 21.0 mm ± 0.8 mm to 24.0 mm ± 0.6 mm zone of inhibition and the ethanol extract produced a 17.0 mm ± 0.9 mm to 23.0 mm ± 0.7 mm inhibition zone with increasing concentrations. Carbohydrates, flavonoids, saponin, phenolic, and terpenoid were common phytoconstituents identified in B. monnieri extracts. Oroxindin showed the best interactions with the binding energies with 5WEW and 6Y4F, -7.5 kcal/mol and -7.4 kcal/mol, respectively. Oroxindin, a bioactive molecule, followed Lipinski's rule of five and exhibited stability in the MD simulation. The overall results suggest that Oroxindin from B. monnieri can be a potent inhibitor for the effective killing of K. pneumoniae and P. mirabilis. Additionally, its safety has been established, indicating its potential for future drug discovery and development in the treatment for UTIs.

Oligonucleotide-based therapies are advanced novel interventions used in the management of various respiratory diseases such as asthma and Chronic Obstructive Pulmonary Disease (COPD). These agents primarily act by gene silencing or RNA interference. Better methodologies and techniques are the need of the hour that can deliver these agents to tissues and cells in a target specific manner by which their maximum potential can be reached in the management of chronic inflammatory diseases. Nanoparticles play an important role in the target-specific delivery of drugs. In addition, oligonucleotides also are extensively used for gene transfer in the form of polymeric, liposomal and inorganic carrier materials. Therefore, the current review focuses on various novel dosage forms like nanoparticles, liposomes that can be used efficiently for the delivery of various oligonucleotides such as siRNA and miRNA. We also discuss the future perspectives and targets for oligonucleotides in the management of respiratory diseases.

Macrophages are considered as the most flexible cells of the hematopoietic system that are distributed in the tissues to act against pathogens and foreign particles. Macrophages are essential in maintaining homeostatic tissue processes, repair and immunity. Also, play important role in cytokine secretion and signal transduction of the infection so as to develop acquired immunity. Accounting to their involvement in pathogenesis, macrophages present a therapeutic target for the treatment of inflammatory respiratory diseases. This review focuses on novel drug delivery systems (NDDS) including nanoparticles, liposomes, dendrimers, microspheres etc that can target alveolar macrophage associated with inflammation, intracellular infection and lung cancer. The physiochemical properties and functional moieties of the NDDS attributes to enhanced macrophage targeting and uptake. The NDDS are promising for sustained drug delivery, reduced therapeutic dose, improved patient compliance and reduce drug toxicity. Further, the review also discuss about modified NDDS for specificity to the target and molecular targeting via anti-microbial peptides, kinases, NRF-2 and phosphodiesterase.

An international, expert led consensus initiative was set up by the Collaborative Ocular Tuberculosis Study (COTS) group to develop systematic, evidence, and experience-based recommendations for the treatment of ocular TB using a modified Delphi technique process. In the first round of Delphi, the group identified clinical scenarios pertinent to ocular TB based on five clinical phenotypes (anterior uveitis, intermediate uveitis, choroiditis, retinal vasculitis, and panuveitis). Using an interactive online questionnaires, guided by background knowledge from published literature, 486 consensus statements for initiating ATT were generated and deliberated amongst 81 global uveitis experts. The median score of five was considered reaching consensus for initiating ATT. The median score of four was tabled for deliberation through Delphi round 2 in a face-to-face meeting. This report describes the methodology adopted and followed through the consensus process, which help elucidate the guidelines for initiating ATT in patients with choroidal TB.
