The Journal of international medical research. 2019;(6):2555-2561
Abstract
OBJECTIVE To study the effect of the leukotriene receptor agonist montelukast combined with methylprednisolone on inflammatory response and peripheral blood lymphocyte subset content in children with mycoplasma pneumonia. METHODS Seventy-four children were enrolled and randomly divided into a standard treatment group and a montelukast plus methylprednisolone group. Serum levels of inflammatory cytokines and corresponding cytokines of T lymphocyte subsets were measured, and peripheral blood was collected to determine the T cell subset content. RESULTS At 3 days and 7 days after treatment, serum MCP-1, PCT, ICAM-1, CXCL8, CRP, IFN-γ, and IL-17 levels and peripheral blood Th1 and Th17 content were significantly decreased in both groups, while serum IL-4 and TGF-β levels and peripheral blood Treg and Th2 content were significantly increased. However, serum MCP-1, PCT, ICAM-1, CXCL8, CRP, IFN-γ, and IL-17 levels and peripheral blood Th1 and Th17 content were significantly lower while serum IL-4 and TGF-β levels and peripheral blood Treg and Th2 content were significantly higher in the montelukast plus methylprednisolone group compared with the control group. CONCLUSION Montelukast combined with methylprednisolone for the treatment of mycoplasma pneumonia can inhibit inflammatory responses and regulate levels of Th1/Th2 and Th17/Treg cells.

Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery. 2019;(4):594-602
Abstract
OBJECTIVE To systematically review the literature on anti-inflammatory medications for treating pediatric obstructive sleep apnea and perform meta-analysis of the available data. DATA SOURCES PubMed/MEDLINE and 4 additional databases. REVIEW METHODS Three authors independently and systematically searched through June 28, 2018, for studies that assessed anti-inflammatory therapy for treatment of pediatric obstructive sleep apnea (OSA). Data were compiled and analyzed using Review Manager 5.3 (Nordic Cochrane Centre). RESULTS After screening 135 studies, 32 were selected for review with 6 meeting inclusion criteria. In total, 668 patients aged 2 to 5 years met inclusion criteria for meta-analysis. Of these, 5 studies (166 children) that evaluated montelukast alone as treatment for pediatric OSA found a 55% improvement in the apnea-hypopnea index (AHI) (mean [SD] 6.2 [3.1] events/h pretreatment and 2.8 [2.7] events/h posttreatment; mean difference [MD] of -2.7 events/h; 95% confidence interval [CI], -5.6 to 0.3) with improvement in lowest oxygen saturation (LSAT) from 89.5 (6.9) to 92.1 (3.6) (MD, 2.2; 95% CI, 0.5-4.0). Two studies (502 children) observing the effects of montelukast with intranasal corticosteroids on pediatric OSA found a 70% improvement in AHI (4.7 [2.1] events/h pretreatment and 1.4 [1.0] events/h posttreatment; MD of -4.2 events/h; 95% CI, -6.3 to -2.0), with an improvement in LSAT from 87.8 (3.1) to 92.6 (2.2) (MD, 4.8; 95% CI, 4.5-5.1). CONCLUSIONS Treatment with montelukast and intranasal steroids or montelukast alone is potentially beneficial for short-term management of mild pediatric OSA.

Abstract
BACKGROUND Perioperative corticosteroid use may reduce acute kidney injury. We sought to test whether methylprednisolone reduces the risk of acute kidney injury after cardiac surgery. METHODS We conducted a prespecified substudy of a randomized controlled trial involving patients undergoing cardiac surgery with cardiopulmonary bypass (2007-2014); patients were recruited from 79 centres in 18 countries. Eligibility criteria included a moderate-to-high risk of perioperative death based on a preoperative score of 6 or greater on the European System for Cardiac Operative Risk Evaluation I. Patients (n = 7286) were randomly assigned (1:1) to receive intravenous methylprednisolone (250 mg at anesthetic induction and 250 mg at initiation of cardiopulmonary bypass) or placebo. Patients, caregivers, data collectors and outcome adjudicators were unaware of the assigned intervention. The primary outcome was postoperative acute kidney injury, defined as an increase in the serum creatinine concentration (from the preoperative value) of 0.3 mg/dL or greater (≥ 26.5 μmol/L) or 50% or greater in the 14-day period after surgery, or use of dialysis within 30 days after surgery. RESULTS Acute kidney injury occurred in 1479/3647 patients (40.6%) in the methylprednisolone group and in 1426/3639 patients (39.2%) in the placebo group (adjusted relative risk 1.04, 95% confidence interval 0.96 to 1.11). Results were consistent across several definitions of acute kidney injury and in patients with preoperative chronic kidney disease. INTERPRETATION Intraoperative corticosteroid use did not reduce the risk of acute kidney injury in patients with a moderate-to-high risk of perioperative death who had cardiac surgery with cardiopulmonary bypass. Our results do not support the prophylactic use of steroids during cardiopulmonary bypass surgery. Trial registration: ClinicalTrials.gov, no. NCT00427388.

Korani, S, Korani, M, Sathyapalan, T, Sahebkar, A
BioFactors (Oxford, England). 2019;(6):835-843
Abstract
The immune system when acts against selfmolecules results in an imbalance in immunologic tolerance leading to the development of several autoimmune diseases (ADs) such as rheumatoid arthritis, asthma, ulcerative colitis, type 1 diabetes, and multiple sclerosis. Improved recognition of the mechanisms of ADs has led to the advancement of the management of these diseases. The principal mediators of ADs are inflammatory molecules. The herbal medicines due to their antioxidant and antiinflammatory properties have an important role in the management of ADs. Crocin is the principal chemical component extracted from saffron, which is a medicinal plant. This review focuses on the therapeutic effects of Crocin in various ADs.

Cho, M, Lee, TY, Kwak, YB, Yoon, YB, Kim, M, Kwon, JS
The Australian and New Zealand journal of psychiatry. 2019;(8):742-759
Abstract
OBJECTIVE Recent evidence suggests that adjuvant anti-inflammatory agents could improve the symptoms of patients with schizophrenia. However, the effects of the adjuvant anti-inflammatory agents on cognitive function, general functioning and side effects have not yet been systematically investigated. The present meta-analysis aimed to explore the effects of anti-inflammatory agents in patients with schizophrenia comprehensively. METHOD We performed a literature search in online databases, including PubMed, EMBASE and the Cochrane Database of Systematic Reviews. Randomized, placebo-controlled double-blind studies that investigated clinical outcomes including psychopathology, neurocognition, general functioning and extrapyramidal side effects were included. The examined anti-inflammatory agents included aspirin, celecoxib, omega-3 fatty acids, estrogen, selective estrogen receptor modulator, pregnenolone, N-acetylcysteine, minocycline, davunetide and erythropoietin. RESULTS Sixty-two double-blind randomized clinical trials studying 2914 patients with schizophrenia met the inclusion criteria for quantitative analysis. Significant overall effects were found for anti-inflammatory agents for reducing total, positive and negative symptom scores in the Positive and Negative Syndrome Scale. Cognitive improvements were significant with minocycline and pregnenolone augmentation therapy. General functioning was significantly enhanced by overall anti-inflammatory agents. There were no significant differences in side effects compared with placebo. Baseline total Positive and Negative Syndrome Scale score and illness duration were identified as moderating factors in the effects of anti-inflammatory augmentation on psychiatric symptom improvements. CONCLUSION The comparative evaluation of efficacy and safety supported the use of anti-inflammatory adjuvant therapy over the use of antipsychotics alone. However, future studies could focus on patients with homogeneous clinical profile to figure out more detailed effects of anti-inflammatory therapy.

Abstract
Studies of the brains of Alzheimer's disease (AD) patients have revealed key neuropathological features, such as the deposition of aggregates of insoluble amyloid-β (Aβ) peptides and neurofibrillary tangles (NFTs). These pathological protein deposits, including Aβ peptides (which form senile plaques) and hyperphosphorylated tau (which aggregates into NFTs), have been assumed to be 'the cause of AD'. Aβ has been extensively targeted to develop an effective disease-modifying therapy, but with limited clinical success. Emerging therapies are also now targeting further pathological processes in AD, including neuroinflammation. This review focuses on the inflammatory and oxidative stress-related changes that occur in AD, and discusses some emerging anti-inflammatory natural products and phytomedicines. Many of the promising compounds are cytokine-suppressive anti-inflammatory drugs (CSAIDs), which target the proinflammatory AP1 and nuclear factor-κB signalling pathways and inhibit the expression of many proinflammatory cytokines, such as interleukin (IL)-1, IL-6, tumour necrosis factor-α, or nitric oxide produced by inducible nitric oxide synthase. However, many of these phytomedicines have not been tested in rigorous clinical trials in AD patients. It is not yet clear if the active compounds reach an effective concentration in the brain (due to limited bioavailability) or if they can slow down AD progression in long-term trials. The authors suggest that it is crucial for both the pharmacological and complementary medicine industries to conduct and fund those studies to significantly advance the field.

Technology and health care : official journal of the European Society for Engineering and Medicine. 2019;(5):519-530
Abstract
BACKGROUND This study was planned to investigate the research trends related to naturally derived anti-inflammatory and anti-obesity components. The main purpose of this study was to find out and develop natural health cosmetic ingredients which has high effects on lipid degradation, moisturizing and elasticity enhancement. OBJECTIVE We all hope this research provided systematic and practical data that can suggest an opportunity to further develop new products. METHODS This is a descriptive research which classified the natural and traditional components that have important obesity management effects based on the experimental technique (in vitro and in vivo). we investigated the effects of 13 natural raw materials selected through preliminary investigation on lipid metabolism related enzyme activity. We first introduced Ainsliaea acerifolea, Onion, pear, Sanguisorba, Limonium tetragonum, Cornus walteri, Loquat, and Loquat-which have recently been shown to be effective in anti-obesity tests, and then described the research methods by showing the effects of onion extracts, Glasswort, Pine Cone (Korean white pine), Orostachys japonicus, African mangoes, Pepper, and Clathratum (sea weed), which actually had effects on anti-obesity in the in vivo experiment. RESULTS As a result of investigating the effect of 13 natural raw materials selected through a preliminary investigation on lipid metabolism related enzyme activity, the study found nature-derived ingredients which induce anti-inflammatory and enhance the anti-obesity enzyme activity, and ingredients showing myriads of biological activities such as anti-oxidant, body fat reduction, lowering of blood cholesterol, and weight control. CONCLUSION In this paper, we would like to delve into the possibility of using natural components with natural lipid-lowering effect, and systematically and practically study if they can actually be helpful to develop new cosmetic products.

Bioscience reports. 2019;(5)
Abstract
Chemotherapy protocol can destroy the reproductive potential of young cancer patients. Doxorubicin (DOX) is a potent anthracycline commonly used in the treatment of numerous malignancies. The purpose of the study was to evaluate the ovarian toxicity of DOX via inflammation and the possible protective effect of the green tea polyphenol epigallocatechin-3-gallate (EGCG). Ovarian tissue of three patients was cultured with 1 µg/ml DOX and/or 10 µg/ml EGCG for 24 and 48 h. Levels of inflammatory factors were determined by quantitative Real-Time PCR, western blot, zimography, and multiplex bead-based immunoassay. Morphological evaluation, damaged follicle count and TUNEL assay were also performed. DOX influenced inflammatory responses by inducing a significant increase in the expression of pro-inflammatory cytokines, such as tumor necrosis factor-α (TNF-α) and cyclooxigenase-2 (COX-2), of inflammatory interleukins (IL), such as interleukin-6 (IL-6) and interleukin-8 (IL-8), and the inflammatory proteins mediators metalloproteinase-2 and metalloproteinase-9 (MMP2 and MMP9). IL-8 secretion in the culture supernatants and MMP9 activity also significantly raised after DOX treatment. Moreover, a histological evaluation of the ovarian tissue showed morphological damage to follicles and stroma after DOX exposure. EGCG significantly reduced DOX-induced inflammatory responses and improved the preservation of follicles. DOX-induced inflammation could be responsible for the ovarian function impairment of chemotherapy. EGCG could have a protective role in reducing DOX-mediated inflammatory responses in human ovarian tissue.

Abstract
Polyphenols are widely acknowledged for their health benefits, especially for the prevention of inflammatory and age-related diseases. We previously demonstrated that hydroxytyrosol (HT) and procyanidins (PCy), alone or in combination, drive preventive anti-osteoathritic effects in vivo. However, the lack of sufficient clinical evidences on the relationship between dietary phytochemicals and osteoarthritis remains. In this light, we investigated in humans the potential osteoarticular benefit of a grapeseed and olive extract (OPCO) characterized for its hydroxytyrosol (HT) and procyanidins (PCy) content. We first validated, in vitro, the anti-inflammatory and chondroprotective properties of the extract on primary cultured human articular chondrocytes stimulated by interleukin-1 beta (IL-1 β). The sparing effect involved a molecular mechanism dependent on the nuclear transcription factor-kappa B (NF-κB) pathway. To confirm the clinical relevance of such a nutritional strategy, we designed an innovative clinical approach taking into account the metabolites that are formed during the digestion process and that appear in circulation after the ingestion of the OPCO extract. Blood samples from volunteers were collected following ingestion, absorption, and metabolization of the extract and then were processed and applied on human primary chondrocyte cultures. This original ex vivo methodology confirmed at a clinical level the chondroprotective properties previously observed in vitro and in vivo.

Rosa canina - Rose hip pharmacological ingredients and molecular mechanics counteracting osteoarthritis - A systematic review.
Gruenwald, J, Uebelhack, R, Moré, MI
Phytomedicine : international journal of phytotherapy and phytopharmacology. 2019;:152958
Abstract
BACKGROUND The successful use of rose hip for the treatment of osteoarthritis is well documented. Several randomized placebo controlled double-blind studies, as mono or combination therapy, have demonstrated treatment efficacy as well as excellent tolerability. PURPOSE This review focuses on the molecular mechanism underlying the clinical effects of rose hip in osteoarthritis (OA). METHODS The database Medline was screened - using the search term "Rosa canina" or "rose hip" - for publications on pharmacological or mechanistic studies with relevance to OA; in addition for findings on pharmacologically active constituents as well as clinical studies. The screening results were complemented by following-up on cited literature. RESULTS In particular, 24 pharmacological studies on Rosa canina or preparations thereof were considered relevant. Potent antioxidant radical scavenging effects are well documented for numerous rose hip constituents besides Vitamin C. Furthermore, anti-inflammatory activities include the reduction of pro-inflammatory cytokines and chemokines, reduction of NF-kB signaling, inhibition of pro-inflammatory enzymes, including COX1/2, 5-LOX and iNOS, reduction of C-reactive protein levels, reduction of chemotaxis and chemoluminescence of PMNs, and an inhibition of pro-inflammatory metalloproteases. CONCLUSION The antioxidant and anti-inflammatory effects of Rosa canina match its clinical action - especially considering new findings on the pharmacological disease pattern of OA. The entirety of several compounds including phenolics, terpenoids, galactolipids, carotenoids, fruit acids and fatty oils can be considered responsible for the observed pharmacological and clinical effects. Further research is needed to eludicate how and in which manner single rose hip compounds interact with their molecular pharmacological targets.
