Prevention And Treatment

The gut microbiota is well known to exert multiple benefits on human health including protection from disease causing pathobiont microbes. It has been recognized that healthy intestinal microbiota is of great importance in the pathogenesis of COVID-19. Gut dysbiosis caused by various reasons is associated with severe COVID-19. Therefore, the modulation of gut microbiota and supplementation of commensal bacterial metabolites could reduce the severity of COVID-19. Many approaches have been studied to improve gut microbiota in COVID-19 including probiotics, bacterial metabolites, and prebiotics, as well as nutraceuticals and trace elements. So far, 19 clinical trials for testing the efficacy of probiotics and synbiotics in COVID-19 prevention and treatment are ongoing. In this narrative review, we summarize the effects of various approaches on the prevention and treatment of COVID-19 and discuss associated mechanisms.

Effective Drugs

The pandemic of the coronavirus disease 2019 (COVID-19) represents an unprecedented challenge to identify effective drugs for prevention and treatment. While the world’s attention is focused on news of COVID-19 vaccine updates, clinical management still requires improvement. Due to the similarity of cancer-induced inflammation, immune dysfunction, and coagulopathy to COVID-19, anticancer drugs, such as Interferon, Pembrolizumab or Bicalutamide, are already being tested in clinical trials for repurposing, alone or in combination. Given the rapid pace of scientific discovery and clinical data generated by the large number of people rapidly infected, clinicians need effective medical treatments for this infection.

Background: Among non-communicable diseases, cardiovascular diseases (CVDs) are the leading cause of mortality and morbidity in global communities. By 2030, CVD-related deaths are projected to reach a global rise of 25 million. Obesity, smoking, alcohol, hyperlipidemia, hypertension, and hyperhomocysteinemia are several known risk factors for CVDs. Elevated homocysteine is tightly related to CVDs through multiple mechanisms, including inflammation of the vascular endothelium. The strategies for appropriate management of CVDs are constantly evolving; medicinal plants have received remarkable attention in recent researches, since these natural products have promising effects on the prevention and treatment of various chronic diseases. The effects of nutraceuticals and herbal products on CVD/dyslipidemia have been previously studied. However, to our knowledge, the association between herbal bioactive compounds and homocysteine has not been reviewed in details. Thus, the main objective of this study is to review the efficacy of bioactive natural compounds on homocysteine levels according to clinical trials and animal studies. Results: Based on animal studies, black and green tea, cinnamon, resveratrol, curcumin, garlic extract, ginger, and soy significantly reduced the homocysteine levels. According to the clinical trials, curcumin and resveratrol showed favorable effects on serum homocysteine. In conclusion, this review highlighted the beneficial effects of medicinal plants as natural, inexpensive, and accessible agents on homocysteine levels based on animal studies. Nevertheless, the results of the clinical trials were not uniform, suggesting that more well-designed trials are warranted.

Dopaminergic Transmission

Cytidine 5’-diphosphocholine has been widely studied in systemic neurodegenerative diseases, like Alzheimer’s disease, Parkinson’s disease, and brain ischemia. The rationale for the use of citicoline in ophthalmological neurodegenerative diseases, including glaucoma, anterior ischemic optic neuropathy, and diabetic retinopathy, is founded on its multifactorial mechanism of action and the involvement in several metabolic pathways, including phospholipid homeostasis, mitochondrial dynamics, as well as cholinergic and dopaminergic transmission, all being involved in the complexity of the visual transmission. This narrative review is aimed at reporting both pre-clinical data regarding the involvement of citicoline in such metabolic pathways (including new insights about its role in the intracellular proteostasis through an interaction with the proteasome) and its effects on clinical psychophysical, electrophysiological, and morphological outcomes following its use in ophthalmological neurodegenerative diseases (including the results of the most recent prospective randomized clinical trials).

Intestinal Microbiocenosis

Intestinal microbiota is the factor that identifies considerably the human health. The impact of the microbial factor on a child begins long before his birth. Children have certain features in forming of immune response and intestinal microbiocenosis even before birth. Decline in diversity of intestinal microbiota is common in children with allergic disease even during first months of life, before allergic pathology development. Capabilities for microbiota development adjustment are sufficiently restricted. However it is clinically proven that early (within the first hours of life) breastfeeding attachment, breastfeeding itself within at least first 6 months of life, the use of prebiotics in milk formulas as well as the use of probiotics can give positive results on allergy management. In this review we present results of recent metaanalyses and consensus papers of international medical communities about use of probiotics and prebiotics in prevention and treatment of allergic diseases. Despite great scientific and practical interest to this topic, authors of metaanalyses bring our attention to the lack of evidence-based clinical trials.

The most common form of peripheral nervous system damage in diabetes mellitus is distal symmetric sensorimotor polyneuropathy (DSSMPN). Chronic hyperglycemia, dyslipidemia, and impaired microcirculation are considered to be the key mechanisms for the development of DSSMPN, but its pathogenesis is still unclear and continues to be studied. The paper analyzes the issues of diagnosis of DSSMPN and the effective principles of patient treatment. It also discusses the use of alpha-lipoic acid (ALA) as a drug for the pathogenetic treatment of DSSMPN and describes the results of clinical trials of its treatment with ALA preparations.

Studies designed to determine the efficacy of alpha-adrenergic agents and antihistamines in the prevention and treatment of otitis media are reviewed. Although some studies demonstrate a pharmacologic rationale for use of decongestants, results of clinical trials fail to demonstrate conclusively that decongestant medication is effective as primary or adjunctive therapy for otitis media. The clinician is advised to await results of future studies before accepting the notion that the systemic administration of sympathomimetic agents and antihistamines is effective in the treatment of otitis media.
