The Effects of Fenugreek Seed Consumption on Blood Pressure: A Systematic Review and Meta-analysis of Randomized Controlled Trials. High Blood Press Cardiovasc Prev 2023; 30:123-133. [PMID: 36763260 DOI: 10.1007/s40292-023-00565-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 01/25/2023] [Indexed: 02/11/2023] Open
Abstract
INTRODUCTION Cardiovascular diseases (CVDs) are growing health issues worldwide. Hypertension (HTN) is one of the most common among CVDs in all populations. Fenugreek has recently been the center of multiple investigations. AIM In this systematic review and meta-analysis, we aimed at gathering and summing up the existing literature regarding the impact of fenugreek seed on systolic blood pressure (SBP) and diastolic blood pressure (DBP). METHODS All major databases (MEDLINE, Cochrane library, EMBASE, and Web of Science) were searched from inception up to 28 June 2022. Relevant randomized controlled trials (RCTs) meeting the inclusion criteria were included and the required data was extracted. The pooled effects were reported as weighted mean differences (WMDs). I-squared test was used to detect between-study heterogeneities. Subgroup analyses were conducted to find sources of heterogeneities. P-values < 0.05 were considered as statistically significant. RESULTS Six RCTs including a total of 373 participants were included in the final meta-analysis. Fenugreek seed supplementation significantly reduced SBP (WMD: 3.46 mmHg, 95% CI - 6.33, - 0.59, P=0.018), but not DBP (WMD: 3.19 mmHg; 95% CI, - 5.82 to 12.21, P=0.488). Subgroup analyses showed that fenugreek seed administered in dosages ≥ 15 g/day and durations ≤ 12 weeks significantly reduced SBP and DBP. CONCLUSION Supplementation with fenugreek seed, especially in dosages ≥ 15 g/day and durations ≤ 12 weeks, might play a role in reducing SBP, but not DBP. However, further investigations are warranted to ensure the clinical relevance of these findings.

Zhang Z, Li Q, Liu F, Wang D. Lycoperoside H protects against diabetic nephropathy via alteration of gut microbiota and inflammation. J Biochem Mol Toxicol 2022; 36:e23216. [PMID: 36156833 DOI: 10.1002/jbt.23216] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Revised: 07/29/2022] [Accepted: 08/30/2022] [Indexed: 11/06/2022]
Abstract
It is well known that hyperglycemia leads to the progression and expansion of various micro and macrovascular disease such as diabetic nephropathy (DN). Lycoperoside H (LH) alkaloidal saponin exhibited the antidiabetic effect, but its DN effect is unclear. In this experimental study, we scrutinized the renal protective effect of LH against the streptozotocin (STZ)-induced DN in rats and explore the underlying mechanism. Sprague-Dawley rats were used in this experimental study and an intraperitoneal injection of STZ (45 mg/kg) was used for the induction of diabetes, rats received the oral administration of LH (20 mg/kg). The blood glucose level, body weight, organ weight (renal and pancreas), and biochemical parameters were estimated. We also scrutinized the effect of LH to enhance intestinal barrier function and suppress inflammation and intestinal permeability. LH significantly (p < 0.001) decreased the glucose level and enhanced the body weight with a reduction of renal weight and boost the pancreas weight. LH significantly (p < 0.001) enhanced the creatinine level and decreased the albumin level, urine volume, urinary albumin excretion rate, and urinary albumin creatinine ratio in the urine. It also suppressed the renal parameters, such as creatinine, blood urea nitrogen, and urea. LH significantly (p < 0.001) altered the level of lipid and antioxidant parameters. LH treatment significantly (p < 0.001) suppressed the cytokines and inflammatory parameters. LH considerably enhanced the Ruminococcaceae, Blautia, and suppressed the abundance of Bifidobacterium, Clostridium, and Turicibacter. It reduced the F/B ratio along with alteration of community abundance of Firmicutes, Actinobacteria, Proteobacteria, Tenericutes, other bacteria, and Bacteroidetes. The current result suggests that LH suppressed the diabetic nephropathological condition via alteration of gut microbiota and inflammation.

Fenugreek Seed Galactomannan Aqueous and Extract Protects against Diabetic Nephropathy and Liver Damage by Targeting NF-κB and Keap1/Nrf2 Axis. TOXICS 2022; 10:toxics10070362. [PMID: 35878267 PMCID: PMC9319613 DOI: 10.3390/toxics10070362] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 06/23/2022] [Accepted: 06/27/2022] [Indexed: 02/06/2023]
Abstract
This investigation was conducted to test the potential of the galactomannan (F-GAL) and aqueous extract (FS-AE) of the Fenugreek seed aqueous to prevent liver and kidney damage extracts in streptozotocin (STZ)-induced T1DM in rats. Non-diabetic and diabetic rats received the normal saline as a vehicle or were treated with FS-EA or F-GAL at a final concentration of 500 mg/kg/each. Treatments with both drugs reduced fasting hyperglycemia and improved serum and hepatic lipid profiles in the control and diabetic rats. Additionally, F-GAL and FS-AE attenuated the associated reduction in the mass and structure of the islets of Langerhans in diabetic rats and improved the structure of the kidneys and livers. In association, they also reduced the generation of reactive oxygen species (ROS), lipid peroxides, factor (TNF-α), interleukin-6 (IL-6), and nuclear levels of NF-κB p65, and improved serum levels of ALT, AST, albumin, and creatinine. However, both treatments increased hepatic and renal superoxide dismutase (SOD) in the livers and kidneys of both the control and diabetic-treated rats, which coincided with a significant increase in transcription, translation, and nuclear localization of Nrf2. In conclusion, FS-AE and F-GAL are effective therapeutic options that may afford a possible treatment for T1DM by attenuating pancreatic damage, hyperglycemia, hyperlipidemia, and hepatic and renal damage.

Abstract
Diabetic nephropathy (DN) is a serious kidney illness characterized by proteinuria, glomerular enlargement, reduced glomerular filtration, and renal fibrosis. DN is the most common cause of end-stage kidney disease, accounting for nearly one-third of all cases of diabetes worldwide. Hyperglycemia is a major factor in the onset and progression of diabetic nephropathy. Many contemporary medicines are derived from plants since they have therapeutic properties and are relatively free of adverse effects. Glycosides, alkaloids, terpenoids, and flavonoids are among the few chemical compounds found in plants that are utilized to treat diabetic nephropathy. The purpose of this review was to consolidate information on the clinical and pharmacological evidence supporting the use of a variety of medicinal plants to treat diabetic nephropathy.

Abstract
ABSTRACT: The present study was designed to investigate the antihyperglycemic and hypolipidemic activities of ethanolic leaf extract of Morus alba (EMA) in Streptozotocin induced diabetic rats. Blood glucose, serum parameters such as glycated haemoglobin (HbA1c), bilirubin, albumin, creatinine, total protein, urea, lipid profile, and urine parameters such as urine protein, creatinine and volume and renal antioxidant enzymes like SOD, CAT, GSH and MDA were estimated at the end of 12 weeks study period. Kidney histopathology was also done. The treatment with EMA showed significant (p<0.05) reduction in the elevated blood glucose, HbA1c, kidney function parameters and lipid profile in STZ induced diabetic rats. Treatment with EMA exerted improvement in antioxidant enzymes as SOD, CAT, GSH and reduction in MDA level profile in STZ induced diabetic rats. Histopathology reveals, EMA showed marked amelioration of glomerulosclerosis caused by STZ. The activities of Morus alba might be due to the presence of antioxidant principles like terpenoids and sterols.

Abstract
Apoptosis is an active response of cells to altered microenvironments, which is characterized by cell shrinkage, chromatin condensation, and DNA fragmentation, in a variety of cell types such as renal epithelial cells, endothelial cells, mesangial cells, and podocytes. Hyperglycemia is among the microenvironmental factors that may facilitate apoptosis, which plays a decisive role in the initiation of diabetic nephropathy. Transforming growth factor-β emerges as a powerful fibrogenic factor in the development of renal hypertrophy. Although, a number of potential treatment strategies exist for diabetic nephropathy, considering the ease of use and bioavailability, phytochemicals stands distinct as the preeminent option. EGCG, a green tea catechin is one such phytochemical which possesses hypoglycemic and antifibrotic activity. The present study aims to explore the potential of EGCG to prevent apoptosis in a high-fat diet and STZ induced diabetic nephropathy rats by assessing renal function, pro-fibrotic marker, and the expression of apoptotic and antiapoptotic proteins. Our results validate EGCG as a potential antiapoptotic agent evidently by improving renal function via down regulating TGF-β, consequently ameliorating diabetic nephropathy. In accordance with this, EGCG might be regarded as a prospective therapeutic candidate in modulating diabetic nephropathy, thus being a promising treatment.

Abstract
BACKGROUND It is well known that diabetes is one of the non-communicable disease affecting a large population worldwide. When diabetes remains untreated or uncontrolled, it leads to further serious complications, affecting vital organs like eyes, kidney, heart, etc. The present study was designed to evaluate effects of umbelliferone, a phytochemical, in treatment of diabetic nephropathy. METHODS Experimental model used was streptozotocin (55mg/kg, ip) induced diabetic nephropathy in male Sprague Dawley rats. After 28days of streptozotocin administration, diabetic animals were treated with umbelliferone at two dose levels, 20 and 40mg/kg for next 28days. RESULTS The results of the study showed that umbelliferone treatment significantly decreased the elevated plasma creatinine and blood urea nitrogen level while significantly increased the total protein and albumin level in diabetic animals. Creatinine clearance was improved in umbelliferone treated animals. Renal oxidative stress was decreased in umbelliferone treated animals significantly. Histopathological study of the kidney was carried out by specific stains like Hematoxylin-Eosin, Periodic Acid Schiff and Masson Trichrome stain. The sections of the kidney showed that umbelliferone treatment decreased the glomerular damage, mesangial matrix expansion as well as the renal fibrosis. Determination of renal transforming growth factor beta one (TGF-β1) expression by immunohistochemical analysis, western blotting and circulating TGF-β1 by ELISA assay showed that umbelliferone decreased the renal tissue and circulating TGF-β1 level. CONCLUSION Umbelliferone treatment can significantly reduce the diabetes induced renal damage and can improve the pathological conditions related to the diabetic nephropathy by down regulation of TGF-β.

Abstract
Diabetic nephropathy is the major cause of end-stage renal disease and effective and new therapeutic approaches are needed in diabetic nephropathy and chronic kidney diseases. Oxidative stress and inflammatory process are important factors contributing to kidney damage by increasing production of oxidants. KEAP1/Nrf2/ARE pathway regulates the transcription of many antioxidant genes and modulation of the pathway up regulates antioxidants. NFB controls the expression of genes involved in the inflammatory response. Natural substances have antioxidant and anti-inflammatory activities and have an impact on NFB and KEAP1/Nrf2/ARE pathways. The preclinical studies explored the effectiveness of whole herbs, plants or seeds and their active ingredients in established diabetic nephropathy. They ameliorate oxidative stress induced kidney damage, enhance antioxidant system, and decrease inflammatory process and fibrosis; most likely by activating KEAP1/Nrf2/ARE pathway and by deactivating NFB pathway. Whole natural products contain balanced antioxidants that might work synergistically to induce beneficial therapeutic outcome. In this context, more clinical studies involving whole plants or herbal products or mixtures of different herbs and plants and their active ingredients might change our strategies for the management of diabetic nephropathy. The natural products might be useful as preventive interventions and studies are required in this field.

Abstract
Plant-derived natural products have long-standing utility toward treating degenerative diseases. It is estimated that about two-thirds of world population depend on traditional medicine for primary medical needs. Fenugreek (Trigonella foenum-graecum Linn.), a short-living annual medicinal plant belonging to Fabaceae family, is used extensively in various parts of the world as herb, food, spice, and traditional medicine. Fenugreek is considered as one of the oldest medicinal plants and its health-promoting effects have been cited in Ayurveda and traditional Chinese medicine. The investigations into the chemical composition and pharmacological actions have seen a renaissance in recent years. Extensive preclinical and clinical research have outlined the pharmaceutical uses of fenugreek as antidiabetic, antihyperlipidemic, antiobesity, anticancer, anti-inflammatory, antioxidant, antifungal, antibacterial, galactogogue and for miscellaneous pharmacological effects, including improving women's health. The pharmacological actions of fenugreek are attributed to diverse array of phytoconstituents. The phytochemical analysis reveals the presence of steroids, alkaloids, saponins, polyphenols, flavonoids, lipids, carbohydrates, amino acids, and hydrocarbons. This review aims to summarize and critically analyze the current available literature to understand the potential of fenugreek for disease prevention and health improvement with special emphasis on cellular and molecular mechanisms. Current challenges and new directions of research on fenugreek are also discussed.

Abstract
Background The microbiota of both humans and animals plays an important role in their health and the development of disease. Therefore, the bacterial flora of the conjunctiva may also be associated with some diseases. However, there are no reports on the alteration of bacterial flora in conjunctiva of diabetic rats in the literature. Therefore, we investigated the changes in bacterial flora in bulbar conjunctiva of rats with streptozotocin (STZ)-induced type I diabetes. Methods A high dose of STZ (60 mg/kg, i.p.) was injected into Sprague-Dawley (SD) rats to induce type I diabetes mellitus (T1DM). The diabetic rats were raised in the animal laboratory and at 8 months post-injection of STZ swab samples were taken from the bulbar conjunctiva for cultivation of aerobic bacteria. The bacterial isolates were identified by Gram staining and biochemical features. The identified bacteria from both diabetic and healthy rats were then compared. Results The diabetic and healthy rats had different bacterial flora present in their bulbar conjunctiva. In total, 10 and 8 bacterial species were found in the STZ and control groups, respectively, with only three species (Enterococcus faecium, Enterococcus gallinarum and Escherichia coli) shared between the two groups. Gram-positive bacteria were common in both groups and the most abundant was Enterococcus faecium. However, after the development of T1DM, the bacterial flora in the rat bulbar conjunctiva changed considerably, with a reduced complexity evident. Conclusions STZ-induced diabetes caused alterations of bacterial flora in the bulbar conjunctiva in rats, with some bacterial species disappearing and others emerging. Our results indicate that the conjunctival bacterial flora in diabetic humans should be surveyed for potential diagnostic markers or countermeasures to prevent eye infections in T1DM patients.
