RESUMO

OBJECTIVE: This study aimed to investigate the associations between concurrent atrial fibrillation and diabetes-related complications among patients with diabetes. RESEARCH DESIGN AND METHODS: This nationwide observational cohort study used the health checkup database from the Korean National Health Insurance Service. Patients diagnosed with diabetes who underwent health checkups between 2009 and 2012 were investigated. The patients with atrial fibrillation were matched in a 1:5 ratio with those without atrial fibrillation using propensity scores. Study outcomes included macrovascular, microvascular (diabetic retinopathy and diabetic nephropathy), and diabetic foot complications. The risks of clinical outcomes were measured using hazard ratios (HRs) with 95% CIs. RESULTS: A total of 65,760 patients with diabetes were analyzed (54,800 without atrial fibrillation and 10,960 with atrial fibrillation). After well-balanced propensity score matching, atrial fibrillation was associated with significantly higher risks of macrovascular complications (HR 1.12, 95% CI 1.09-1.16), diabetic nephropathy (HR 1.23, 95% CI 1.16-1.30), and diabetic foot complications (HR 1.13, 95% CI 1.09-1.17) compared with no atrial fibrillation, while the risk of diabetic retinopathy was comparable (HR 0.99, 95% CI 0.96-1.03). Patients with atrial fibrillation had a significantly higher risk of diabetic foot amputation (HR 4.12, 95% CI 1.98-8.56). CONCLUSIONS: Among patients with diabetes, concurrent atrial fibrillation was associated with increased risks for diabetes-related macrovascular complications, diabetic nephropathy, and diabetic foot. Such patients require holistic management to reduce the risk of adverse outcomes.

RESUMO

This study aimed to evaluate the efficacy of nifedipine controlled-release tablets combined with sacubitril valsartan in diabetic nephropathy (DN) patients with hypertension. One hundred and twelve DN patients with hypertension were enrolled. They were randomly divided into the control group (treated with nifedipine controlled-release tablets combined with valsartan) and the observation group (treated with nifedipine controlled-release tablets combined with sacubitril valsartan). Renal function, endothelial function and inflammatory response were examined. After three-months treatment, the levels of clinical indexes (glycosylated hemoglobin, fasting blood glucose, systolic and diastolic blood pressure), renal function indicators (urinary albumin excretion rate, blood urea nitrogen, serum creatinine and cystatin C), endothelial function indicators (microalbumin, angiotensin II, thrombomodulin and cartilage oligomeric matrix protein) and inflammatory response factors (interleukin-6 and tumor necrosis factor-α) in the observation group were significantly lower than those in the control group. Nifedipine controlled-release tablets combined with sacubitril valsartan could effectively alleviate the progression of DN combined with hypertension.

RESUMO

Diabetes Mellitus is a highly prevalent condition in which Diabetes Mellitus type 2 is the most common. Diabetic Kidney Disease is one of the most relevant complications and affects approximately one-third of patients with Diabetes Mellitus. It is characterized by increased urinary protein excretion and a decrease in glomerular filtration rate, assessed by serum creatinine levels. Recent studies have shown that vitamin D levels are low in these patients. This study aimed to conduct a systematic review of the effects of vitamin D supplementation on proteinuria and creatinine, which are important markers for assessing the severity of kidney disease in patients with Diabetic Kidney Disease. PUBMED, EMBASE, and COCHRANE databases were consulted, Preferred Reporting Items for a Systematic Review and Meta-Analysis guidelines were followed, and the COCHRANE toll for bias assessment was applied. Six papers were quantitative studies and fulfilled the inclusion criteria for this review. The results showed that vitamin D supplementation of 50,000 I.U./week for 8 weeks effectively reduced proteinuria and creatinine in patients with Diabetic Kidney Disease, particularly in patients with Diabetes Mellitus type 2. Vitamin D supplementation is beneficial for patients with Diabetic Kidney Disease by having essential effects on disease-related inflammatory markers, such as the reduction of proteinuria and creatinine. However, more clinical trials must be conducted to evaluate the intervention among more significant numbers of patients.

RESUMO

BACKGROUND: Vitamin D supplementation is associated with a lower incidence of diabetic nephropathy (DN); however, whether this association is causative is uncertain. METHODS: We used two-sample Mendelian randomization to examine the causal influence of vitamin D on diabetic nephropathy in 7,751 individuals with type I diabetes-related nephropathy (T1DN) and 9,933 individuals with type II diabetes-related nephropathy (T2DN). Meanwhile, we repeated some previous studies on the influence of KIM-1 (kidney injury molecule 1) and body mass index (BMI) on DN. Additionally, to test the validity of the instruments variable for vitamin D, we conducted two negative controls Mendelian randomization (MR) on breast and prostate cancer, and a positive control MR on multiple sclerosis. RESULTS: Results of the MR analysis showed that there was no causal association between 25(OH)D with the early/later stage of T1DN (early: OR = 0.903, 95%CI: 0.229 to 3.555; later: OR = 1.213, 95%CI: 0.367 to 4.010) and T2DN (early: OR = 0.588, 95%CI: 0.182 to 1.904; later: OR = 0.904, 95%CI: 0.376 to 2.173), nor with the kidney function of patients with diabetes mellitus: eGFRcyea (creatinine-based estimated GFR) (Beta = 0.007, 95%CI: -0.355 to 0.369)) or UACR (urinary albumin creatinine ratio) (Beta = 0.186, 95%CI: -0.961 to 1.333)). CONCLUSIONS: We found no evidence that Vitamin D was causally associated with DN or kidney function in diabetic patients.

RESUMO

Bioactive natural products are essential components for drug development. Protein glycation in diabetic subjects leads to diabetic complications as nephropathy and neuropathy. We investigated the impact of pomegranate hexane extract (PHE) as antioxidant, anti-inflammatory, and antiglycation in diabetic rats. Gas chromatography/mass spectrum (GC/MS) analysis of PHE revealed presence of resorcinol, catechol, tau-cadinol, metacetamol, scopoletin, phytol, and phenol, 3-pentadecyl as the most active ingredients that related to biological activity. Results obtained showed that, PHE increased serum aldose reductase and total antioxidant activity compared with untreated diabetic rats (p < 0.001). In addition, PHE exert antioxidant by enhancing, catalase and SOD (p < 0.001) and decreased MDA (p < 0.001), anti-inflammatory by inhibition production of 1 ß (IL-1ß), tumor necrosis factor (TNF-α) (p < 0.001), and AGEs (p < 0.001) against nephropathy in diabetic rats compared with untreated group. It was concluded that, pomegranate is promising in development a functional biomolecule in treatment and protection against diabetic complications as nephropathy. More study required to investigate the molecular action of these molecules.

RESUMO

Diabetic nephropathy (DN) is a renal complication of diabetic hyperglycemia. The Signal transducer and activator of transcription 3 (Stat3) is a center molecule of the chronic inflammation causing DN progression. Therefore, the study investigated the possible inhibitory effects of Rutin (Ru) and Selenium (Se), formulated as nanoparticles (SeNPs), on Stat3 pathway in streptozotocin (STZ)-induced DN in Sprague-Dawley rats. Ru (100 mg/kg/orally) and SeNPs (equivalent to 5 mg of Se/kg/orally) were given as treatment for eight weeks. An assessment of fasting blood glucose, renal function biomarkers, GSH, and MDA was carried out spectrophotometrically. ELISA assessment of renal IL-6, NF-κB, TNF-α, Jak-2, and p-Stat3 was performed. Sirt-1, Nrf-2, and HO-1 were assessed immunohistochemically. DN group receiving Ru + SeNPs showed a decrease in fasting blood glucose, serum creatinine, and urea (163.8 ± 22.8, 0.54 ± 0.1, and 53.6 ± 25.7 mg/dl, respectively), compared to the DN group (443.8 ± 42.72, 1.58 ± 0.4, and 281.8 ± 47.35 mg/dl, respectively). In addition, it exhibited elevation in the levels of Sirt-1, Nrf-2 and HO-1 compared to the DN group. Finally, Ru + SeNPs exhibited a significant reduction in IL-6, NF-κB, TNF-α, Jak-2, and p-Stat3 (42.8 ± 10.3, 1.2 ± 0.1, 53.4 ± 3.87, 0.8 ± 0.06 and 1.1 ± 0.2 U/g tissue, respectively) when compared to the DN group (155.3 ± 13.97, 2.8 ± 0.3, 105.5 ± 32.84, 2.03 ± 0.2 and 2.56 ± 0.15 U/g tissue, respectively). Therefore, combining Ru with SeNPs has a potential renoprotective effect against DN by upregulating Nrf-2/HO-1 and downregulating Jak-2/Stat3 Pathways.

RESUMO

In diabetes kidney disease (DKD), orthostatic hypotension and supine hypertension often coexist, which, when uncontrolled, contributes to the progression of proteinuria and renal dysfunction. Chronotherapy and elevation of the head of the bed during sleep are feasible clinical measures and could contribute to the control of supine hypertension and proteinuria in this group of patients. This study consists of a series of cases, in which nine consecutive patients with DKD, dysautonomia and supine hypertension (intervention group) were instructed to use chronotherapy and inclination of the head of the bed in six degrees during sleep. These patients were compared with a historical control group. The primary outcome was proteinuria behavior. The intervention group had a significant drop in proteinuria levels, while there was an increase in proteinuria in the control group (variation in the proteinuria/creatininuria index in an isolated sample from the intervention group: -6.60 ± 3.90 g/g; variation in the group control: +1.70 ± 7.10 g/g, p = 0.008). Chronotherapy and six-degree inclination of the head of the bed during sleep were associated with a significant decrease in proteinuria in patients in the intervention group, with conversion of nephrotic into non-nephrotic proteinuria in most of these patients.

RESUMO

INTRODUCTION: The prevalence of diabetes mellitus has increased tremendously in the last two decades among women of reproductive age and this is mainly due to the pandemic of obesity. Diabetes mellitus is a well-known cause of maternal and neonatal complications in pregnancy. Diabetic nephropathy is a marker of severe diabetes and results in organ damage. However, only a small number of studies have evaluated the implications of diabetic nephropathy on pregnancy complications, with most having 50 to 100 nephropathy subjects. Our study aims to compare pregnant women with diabetes mellitus complicated by nephropathy or not and evaluate the relationship with obstetrical and perinatal morbidity and mortality, on a larger population. METHODS: This was a population-based study using data from the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample (HCUP-NIS) including women who delivered between 2004 and 2014. Multivariate logistic regression was used to control for confounding effects. RESULTS: Among 86,615 pregnancies that were complicated by diabetes mellitus, 1,241 (1.4%) had diabetic nephropathy. Diabetic nephropathy was strongly associated with preeclampsia (aOR 2.3, 95% CI 1.90-2.68), as well as chronic hypertension with superimposed preeclampsia or eclampsia (aOR 4.2, 95% CI 3.53-5.01), preterm birth (aOR 1.8, 95% CI 1.59-2.1), and blood transfusion (aOR 3.6 95% CI 2.82-4.46). Both groups were similar in age and income. CONCLUSION: Diabetic nephropathy is associated with increased obstetrical and perinatal morbidity compared to diabetes mellitus alone. These patients may benefit from a high dose of folic acid, more vigilant antenatal surveillance, delivery in a tertiary care center, and more rigorous screening and prevention methods for pregnancy-induced hypertension diseases at antenatal care visits.

RESUMO

Severe acute respiratory syndrome (SARS)-CoV-2 virus causes novel coronavirus disease 2019 (COVID-19) with other comorbidities such as diabetes. Diabetes is the most common cause of diabetic nephropathy, which is attributed to hyperglycemia. COVID-19 produces severe complications in people with diabetes mellitus. This article explains how SARS-CoV-2 causes more significant kidney damage in diabetic patients. Importantly, COVID-19 and diabetes share inflammatory pathways of disease progression. SARS-CoV-2 binding with ACE-2 causes depletion of ACE-2 (angiotensin-converting enzyme 2) from blood vessels, and subsequently, angiotensin-II interacts with angiotensin receptor-1 from vascular membranes that produce NADPH (nicotinamide adenine dinucleotide hydrogen phosphate) oxidase, oxidative stress, and constriction of blood vessels. Since diabetes and COVID-19 can create oxidative stress, we hypothesize that COVID-19 with comorbidities such as diabetes can synergistically increase oxidative stress leading to end-stage renal failure and death. Antioxidants may therefore prevent renal damage-induced death by inhibiting oxidative damage and thus can help protect people from COVID-19 related comorbidities. A few clinical trials indicated how effective the antioxidant therapy is against improving COVID-19 symptoms, based on a limited number of patients who experienced COVID-19. In this review, we tried to understand how effective antioxidants (such as vitamin D and flavonoids) can act as food supplements or therapeutics against COVID-19 with diabetes as comorbidity based on recently available clinical, preclinical, or in silico studies.

RESUMO

Accumulating evidence reveals that both inflammation and lymphocyte dysfunction play a vital role in the development of diabetic nephropathy (DN). Hyperoside (HPS) or quercetin-3-O-galactoside is an active flavonoid glycoside mainly found in the Chinese herbal medicine Tu-Si-Zi. Although HPS has a variety of pharmacological effects, including anti-oxidative and anti-apoptotic activities as well as podocyte-protective effects, its underlying anti-inflammatory mechanisms remain unclear. Herein, we investigated the therapeutic effects of HPS on murine DN and the potential mechanisms responsible for its efficacy. We used C57BLKS/6J Lepdb/db mice and a high glucose (HG)-induced bone marrow-derived macrophage (BMDM) polarization system to investigate the potentially protective effects of HPS on DN. Our results showed that HPS markedly reduced diabetes-induced albuminuria and glomerular mesangial matrix expansion, accompanied with a significant improvement of fasting blood glucose level, hyperlipidaemia and body weight. Mechanistically, pretreatment with HPS effectively regulated macrophage polarization by shifting proinflammatory M1 macrophages (F4/80+CD11b+CD86+) to anti-inflammatory M2 ones (F4/80+CD11b+CD206+) in vivo and in bone marrow-derived macrophages (BMDMs) in vitro, resulting in the inhibition of renal proinflammatory macrophage infiltration and the reduction in expression of monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor (TNF-α) and inducible nitric oxide synthase (iNOS) while increasing expression of anti-inflammatory cytokine Arg-1 and CD163/CD206 surface molecules. Unexpectedly, pretreatment with HPS suppressed CD4+ T cell proliferation in a coculture model of IL-4-induced M2 macrophages and splenic CD4+ T cells while promoting their differentiation into CD4+IL-4+ Th2 and CD4+Foxp3+ Treg cells. Taken together, we demonstrate that HPS ameliorates murine DN via promoting macrophage polarization from an M1 to M2 phenotype and CD4+ T cell differentiation into Th2 and Treg populations. Our findings may be implicated for the treatment of DN in clinic.

RESUMO

The objective of our study was to evaluate the effect of Physalis peruviana L. fruits in the management of diabetes and diabetic nephropathy in relation to its metabolic profile. In-vitro α-amylase, ß-glucosidase, and lipase inhibition activities were assessed for the ethanolic extract (EtOH) and its subfractions. Ethyl acetate (EtOAc) fraction showed the highest α-amylase, ß-glucosidase, and lipase inhibition effect. In vivo antihyperglycemic testing of EtOAc in streptozotocin (STZ)-induced diabetic rats showed that it decreased the blood glucose level, prevented the reduction in body weight, improved serum indicators of kidney injury (urea, uric acid, creatinine), and function (albumin and total protein). EtOAc increased autophagic parameters (LC3B, AMPK) and depressed mTOR contents. Histopathology revealed that EtOAc ameliorated the pathological features and decreased the glycogen content induced by STZ. The immunohistochemical analysis showed that EtOAc reduced P53 expression as compared to the STZ-diabetic group. UPLC-ESI-MS/MS metabolite profiling of EtOAc allowed the identification of several phenolic compounds. Among the isolated compounds, gallic acid, its methylated dimer and the glycosides of quercetin had promising α-amylase and ß-glucosidase inhibition activity. The results suggest that the phenolic-rich fraction has a protective effects against diabetic nephropathy presumably via enhancing autophagy (AMPK/mTOR pathway) and prevention of apoptosis (P53 suppression).

RESUMO

The highly expressed P-glycoprotein (Pgp) in the intestine plays a key role in preventing drugs across the intestinal epithelium, which linked by tight junctions (TJs). Thus increasing the oral bioavailability of Pgp substrate-like drugs (PSLDs) remains a great challenge. Herein, we construct a nanocarrier system derived from Brij-grafted-chitosan (BC) to enhance the oral bioavailability and therapeutic effect of berberine (BBR, a typical PLSD) against diabetic kidney disease. The developed BC nanoparticles (BC-NPs) are demonstrated to improve the intestinal permeability of BBR via transiently and reversibly modulating the intercellular TJs (paracellular pathway) and Pgp-mediated drug efflux (transcellular pathway). As compared to free BBR and chitosan nanoparticles, the BC-NPs enhanced the relative oral bioavailability of BBR in rats (4.4- and 2.7-fold, respectively), and the therapeutic potency of BBR in renal function and histopathology. In summary, such strategy may provide an effective nanocarrier system for oral delivery of BBR and PSLDs.

RESUMO

Oxidative stress and inflammation are implicated in the occurrence and progression of diabetic nephropathy (DN). Diphenyl diselenide (DPDS) is a stable and simple diaryl diselenide with anti-hyperglycemic, anti-inflammatory, and antioxidant activities. However, the effects of DPDS on DN are still unclear to date. Herein, we aimed to explore whether DPDS could improve renal dysfunction in streptozotocin (STZ)-induced diabetic rats and its underlying mechanisms. STZ-induced DN rats were administered with DPDS (5 or 15 mg/kg) or metformin (200 mg/kg) once daily by intragastric gavage for 12 weeks. DPDS supplementation significantly improved hyperglycemia, glucose intolerance, dyslipidemia, and the renal pathological abnormalities, concurrent with significantly reduced serum levels of creatinine, urea nitrogen, urine volume, and urinary levels of micro-albumin, ß2-microglobulin and N-acetyl-glucosaminidase activities. Moreover, DPDS effectively promoted the activities of antioxidant enzymes, and reduced the levels of MDA and pro-inflammatory factors in serum and the kidney. Furthermore, DPDS supplementation activated the renal Nrf2/Keap1 signaling pathway, but attenuated the high phosphorylation levels of NFκB, JNK, p38 and ERK1/2. Altogether, the current study indicated for the first time that DPDS ameliorated STZ-induced renal dysfunction in rats, and its mechanism of action may be attributable to suppressing oxidative stress via activating the renal Nrf2/Keap1 signaling pathway and mitigating inflammation by suppressing the renal NFκB/MAPK signaling pathways, suggesting a potential therapeutic approach for DN.

RESUMO

The effects of Liuwei Dihuang pill (LWDH) on diabetic nephropathy-related osteoporosis (DNOP) are unclear. The present study aimed to evaluate the effects of LWDH on KDM7A and Wnt/ß-catenin signaling pathway in DNOP rats and the high glucose-induced MC3T3-E1 cells. A DNOP model was prepared by streptozotocin in 9-week-old male Sprague-Dawley (SD) rats to evaluate the effects of LWDH. The cell viability and differentiation capacity of high glucose-induced MC3T3-E1 cells were determined by CCK-8 assay, Alizarin Red staining, and alkaline phosphatase (ALP) staining, respectively. Furthermore, the expressions of KDM7A and Wnt1/ß-catenin pathway-related proteins were determined by Western blot analysis. Treatment of DNOP rats with LWDH could significantly ameliorate the general state, degradation of renal function, and renal pathological changes. LWDH decreased the levels of TNF-α, IL-6, IL-8, IL-1ß, ALP, and TRAP, and increased the calcium, phosphorus in serum, as well as decreased the level of the calcium and phosphorus in the urine. Besides, LWDH significantly improved bone mineral density (BMD), bone volume (BV), and the bone microstructure of DNOP rats. Moreover, LWDH increased the levels of the elastic modulus, ultimate load, and bending strength in the femurs. In MC3T3-E1 cells, serum-containing LWDH significantly increases in cell viability and osteoblastic differentiation capability. The expression of α-SMA, vimentin, KDM7A, Wnt1 and ß-catenin were significantly down-regulated, and the E-cadherin, H3K9-Me2, H3K27-Me2, BMP-4, BMP-7, Runx2, osteocalcin, and Col1a1 were significantly up-regulated with LWDH treatment. The present study shows that LWDH has a therapeutic effect on DNOP, in part, through down-regulation of KDM7A and Wnt/ß-catenin pathway.

RESUMO

Chronic pain not only has the greatest negative effect on quality of life compared with other chronic health problems but also contributes to the greatest disability worldwide. Management of chronic neuropathic pain is particularly challenging given its association with other pain processes, the fact that less than half of patients respond to a single pain medication, and the lack of evidence regarding combination therapy (i.e. a treatment regimen that combines several scheduled pain medications) safety and efficacy. Given these challenges, there is a growing interest in the application of complementary and alternative medicine (CAM) therapies such as yoga, acupuncture, and hypnosis. We present the case of a 67-year-old male with severe diabetic neuropathy refractory to first, second, and third-line treatments. His disabling pain precipitated premature retirement, contributing to severe depression with suicidality requiring hospitalization. Ultimately, he experienced relief through an integrative health regimen, and he identified hypnosis as the most effective therapy for his pain. Through individual and group sessions, recordings, and daily self-hypnosis, he improved both his chronic pain symptomatology and quality of life, simultaneously decreasing opioid use. Simulation modeling analysis of his pain ratings over time showed that they reliably decreased after engaging in hypnosis, r = -.33, p =.001. A growing body of research suggests that hypnosis is beneficial as part of an integrative treatment approach to chronic pain and enhances the efficacy of other therapies. Our medically challenging case study supports that hypnosis may serve as a viable and durable treatment for chronic neuropathic pain.

RESUMO

BACKGROUND: Diabetic nephropathy (DN) is among the common and serious complications of diabetes and is also a major cause of end-stage kidney disease. Early DN is also called diabetic microalbumin period, the main treatment is in the control of blood sugar on the basis of kidney protection and urine lowering protein. There are few effective methods of western medicine treatment, and most of them are accompanied by adverse reactions. But some studies have shown that traditional Chinese medicine has achieved the curative effect and has certain superiority. However, there are few systematic reviews on the treatment of traditional Chinese herbal medicine for early DN currently. Therefore, this study conducted a systematic review of clinical efficacy and safety of Chinese herbal medicine for the treatment of patients with early DN, aim to comprehensively analyze the role of traditional Chinese herbal medicine in the treatment of early DN. METHODS AND ANALYSIS: The protocol of this systematic review and meta-analysis was registered on the INPLASY website (https://inplasy.com/inplasy-2020-4-0139/) and INPLASY registration number is INPLASY202040139. A systematic literature search will be conducted in 3 English database and 4 Chinese databases with a language limitation of English and Chinese. Search for clinical research literature on Chinese herbal medicine treatment of DN published in domestic and foreign biomedical journals. The time is limited from January 2010 to February 2020. We will investigate heterogeneity across studies and publication bias. To assess the risk of bias and quality of the included studies, we will use the Cochrane Collaboration's ROB tool. According to the relevant standards in the Cochrane Intervention System Evaluation Manual, it will be divided into low risk, high risk, and unclear. We will also use the RevMan 5.3 software and Stata 13.0 software for meta-analysis of the effectiveness and symptom scores of DN proteinuria. ETHICS AND DISSEMINATION: The ethical considerations are not required because the systematic review is based on published studies. The systematic review and meta-analysis will be published in a peer-reviewed Journal.

RESUMO

Diabetic nephropathy and cardiomyopathy are two major causes of mortality among patients with diabetes mellitus (DM). Since current diabetic medications are associated with various side effects, the naturally occurring plant-derived compounds are in demand. Bioflavonoids originating from vegetables and medicinal plants have beneficial effects on diabetes by improving glycemic control, lipid metabolism, and anti-oxidant status. The present study is focused on the effect of rutin against alloxan induced diabetic nephropathy and cardiomyopathy. Male albino Wistar rats were divided into four groups, each of six rats. Group I control rats received 0.9% saline as a single dose intraperitoneally. Group II rats were induced diabetes with a single dose of alloxan monohydrate (150 mg/kg body weight in 0.9% saline) intraperitoneally. Group III rats received 0.28 M of NH4Cl in drinking water for 3 days for the experimental induction of metabolic acidosis. Group IV rats were injected with a single dose of alloxan monohydrate (150 mg/kg bodyweight) and administered rutin hydrate (100 mg/kg) for a period of 4 weeks by oral gavage. Administration of rutin prevented urinary ketone body formation and decreased serum creatinine and urea levels in alloxan induced diabetic rats. Rutin supplementation reduced the levels of serum triglycerides and cholesterol in diabetic rats. Gene expression profiling of metabolic acidosis related genes (AQP2, AQP3 and V2R) and also histopathological results demonstrated the protective effect of rutin against diabetic ketoacidodis and fibrosis. The results of the present study revealed rutin administration prevents the progression of diabetic nephropathy and cardiomyopathy through amelioration of fibrosis and metabolic acidosis.

RESUMO

Diabetic kidney disease and its comorbid conditions, including atherosclerotic cardiovascular disease, heart failure, diabetes, and obesity, are interconnected conditions that compound the risk of kidney failure and cardiovascular mortality, and exponentiate health care costs. Sodium glucose cotransporter 2 inhibitor (SGLT2i) and glucagon-like peptide 1 receptor agonist (GLP-1 RA) are novel diabetes medications that prevent cardiovascular events and kidney failure. Clinical trials exploring the cardiovascular and kidney outcomes of SGLT2i and GLP-1 RA have fundamentally shifted the treatment paradigm of diabetes. Clinical guidelines for diabetes management recommend a more holistic approach beyond glycemic control and emphasize heart and kidney protection of SGLT2i and GLP-1 RA. However, the adoption of prescribing SGLT2i and GLP-1 RA for patients with diabetes and high cardiovascular and kidney risk has been slow. In this review, we provide a decision-making tool to help clinicians determine when to consider SGLT2i and GLP-1 RA for heart and kidney protection. First, we discuss a comprehensive risk assessment for patients with diabetic kidney disease. We compare the effectiveness of SGLT2i and GLP-1 RA for different risk categories. Then, we present a decision algorithm using cardiovascular and kidney failure risk stratification and the strength of current evidence for the use of SGLT2i and GLP-1 RA. Lastly, we review the adverse effects of SGLT2i and GLP-1 RA and propose mitigation strategies.

RESUMO

BACKGROUND: Homocysteine levels are elevated in patients with type 1 diabetes mellitus (T1DM) and could induce renal injury. B vitamins have an important role in preventing microvascular complications of diabetes. AIM: We performed a randomized-controlled trial of oral supplementation with vitamin B complex as an adjuvant therapy for nephropathy in pediatric T1DM patients and assessed its relation to homocysteine and cystatin C as a marker of nephropathy. METHODS: This trial included 80 T1DM patients with microalbuminuria, despite oral angiotensin-converting enzyme inhibitors, aged 12-18 years with at least 5 years disease duration and HbA1c ≤8.5%. Patients were randomly assigned into two groups; intervention group which received oral vitamin B complex (B1, B6 and B12) once daily and placebo group. Both groups were followed-up for 12 weeks with assessment of plasma homocysteine, HbA1c, urinary albumin excretion (UAE) and cystatin C. RESULTS: Both groups were well-matched in baseline clinical and laboratory parameters. Baseline homocysteine levels were elevated in both groups compared with reference control values. After 12 weeks, supplementation with vitamin B complex for the intervention group resulted in a significant decrease of homocysteine, fasting blood glucose, HbA1c, triglycerides, total cholesterol, UAE and cystatin C compared with baseline levels (p < 0.001) and with placebo group (p < 0.001). No adverse reactions were reported. Baseline cystatin C was negatively correlated to vitamin B12 (r = -0.77, p = 0.001). CONCLUSIONS: Vitamin B complex improved glycemic control and renal function through decreasing homocysteine and could be a safe and effective strategy for treatment of early stage nephropathy in pediatric T1DM. This trial was registered at ClinicalTrials.gov (NCT03594240).
