SLU-PP-332 activates estrogen receptor-related orphan receptors, increasing energy expenditure, fatty acid oxidation, and decreasing fat mass accumulation. The drug enhances mitochondrial function and cellular respiration in skeletal muscle cell lines, increases the expression of an estrogen receptor-related orphan receptor target gene, and enhances mitochondrial respiration in C2C12 myocytes. The drug also increases oxidative fibers in skeletal muscle and improves exercise endurance in C57BL/6J mice.

Introduction: Lymphocytosis is characterized by an elevation in the absolute lymphocyte count (ALC) to over 4000 lymphocytes per microliter among adults. In lymphocytosis, the important matter is whether lymphocytosis is a benign reactive condition or a neoplastic lymphoproliferative disorder (LPD), which can be determined by immunophenotyping methods by flow cytometry. Objectives: Due to the need to use flow cytometry to confirm the diagnosis of patients with lymphocytosis, the purpose of this study was to compare the frequency of benign reactive lymphocytosis and LPDs in patients with persistent lymphocytosis using flow cytometry in the peripheral blood and report the results based on the patient’s demographic characteristics. Materials and Methods: This study was a cross-sectional study and the study population was all peripheral blood samples referred to Seyed Al-Shohada hospital in Isfahan to study the cause of absolute and persistent lymphocytosis by immunophenotyping analysis through flow cytometry between 2015 and 2020. Inclusion criteria were patients over 18 years of age with absolute lymphocytosis in complete blood count (CBC) or peripheral blood smear (PBS) who were examined by flow cytometry. Results: This study involved 222 samples, 139 (62.6%) of the cases were male. The mean age was 60.41 (15.91) years. All samples had absolute lymphocytosis and were divided into two groups: benign, with 62 (27.9%), and malignant, with 160 (72.1%). Conclusion: The relationship between gender and malignancy showed that the male gender was associated with an increased risk of malignancy. The mean age between the two groups of malignant and benign was determined by independent t test, and it was shown that the mean (±standard deviation) age of malignant cases is higher than the mean age of benign cases. It is recommended that cases of suspected lymphoproliferative cases and cases with cell counts below the lymphocytosis threshold be investigated in separate studies.
引言淋巴细胞增多症的特征是成人绝对淋巴细胞计数(ALC)升高到每微升4000个以上。在淋巴细胞增多症中,重要的是淋巴细胞增多症是良性反应性疾病还是肿瘤性淋巴增生性疾病(LPD),这可通过流式细胞术的免疫分型方法来确定。目的:由于需要使用流式细胞术对淋巴细胞增多症患者进行确诊,本研究旨在使用流式细胞术比较持续性淋巴细胞增多症患者外周血中良性反应性淋巴细胞增多症和 LPD 的频率,并根据患者的人口统计学特征报告结果。材料和方法:本研究为横断面研究,研究对象为 2015 年至 2020 年期间转诊至伊斯法罕 Seyed Al-Shohada 医院的所有外周血样本,通过流式细胞术进行免疫分型分析,研究绝对淋巴细胞增多症和持续性淋巴细胞增多症的病因。纳入标准为全血细胞计数(CBC)或外周血涂片(PBS)中出现绝对淋巴细胞增多并接受流式细胞术检查的 18 岁以上患者。研究结果本研究涉及 222 个样本,其中 139 例(62.6%)为男性。平均年龄为 60.41(15.91)岁。所有样本均有绝对淋巴细胞增多,并分为两组:良性样本 62 例(27.9%)和恶性样本 160 例(72.1%)。结论是性别与恶性肿瘤之间的关系表明,男性患恶性肿瘤的风险增加。通过独立 t 检验确定恶性和良性两组之间的平均年龄,结果显示恶性病例的平均年龄(±标准差)高于良性病例的平均年龄。建议对疑似淋巴增生病例和细胞计数低于淋巴细胞增多阈值的病例进行单独研究。

Contrast-associated acute renal injury is a common complication that occurs after the administration of contrast media for diagnostic or therapeutic purposes. It is characterized by a sudden decline in kidney function within 48-72 hours after the administration of contrast media. The incidence of contrast-associated acute renal injury varies depending on the patient’s risk factors and the type and amount of contrast media used. Sodium-glucose co-transporter 2 (SGLT2) inhibitors are a group of antidiabetic drugs that inhibit the reabsorption of glucose in the nephrons, running to raise urinary glucose excretion and improve glycemic control. Recent studies have shown that SGLT2 inhibitors may have a protective effect against contrast-associated acute renal injury. Preventive measures for contrast-associated acute renal injury include hydration, minimizing contrast volume and rate of administration, and avoiding contrast in high-risk patients. The administration of SGLT2 inhibitors may also be a useful preventive measure in patients at risk for contrast-associated acute renal injury.
造影剂相关急性肾损伤是为诊断或治疗目的使用造影剂后出现的一种常见并发症。其特点是在使用造影剂后 48-72 小时内肾功能突然下降。造影剂相关性急性肾损伤的发生率因患者的风险因素以及造影剂的类型和用量而异。钠-葡萄糖协同转运体 2(SGLT2)抑制剂是一组抗糖尿病药物,可抑制肾小球对葡萄糖的重吸收,从而提高尿糖排泄量并改善血糖控制。最近的研究表明,SGLT2 抑制剂可能对造影剂相关急性肾损伤有保护作用。造影剂相关急性肾损伤的预防措施包括补充水分、尽量减少造影剂用量和给药速度,以及避免高危患者使用造影剂。对于有造影剂相关急性肾损伤风险的患者,服用 SGLT2 抑制剂也是一种有效的预防措施。

Contrast-induced nephropathy (CIN) is a well-known complication of contrast media administration for diagnostic and therapeutic purposes. The incidence of CIN has increased with the widespread use of diagnostic imaging and contrast media. CIN is a pathological condition that typically occurs within 48 hours of exposure to contrast material and results in an increase in serum creatinine levels of more than 44 µmol/L (0.5 mg/dL) or 25% above baseline or an increase in serum creatinine of more than 1.5 times the baseline level within 7 days of exposure to contrast material or a reduction in urine output to less than 0.5 mL/h for at least 6 hours after exposure to contrast material. The mechanism of CIN is not fully understood, but it is thought to involve direct nephrotoxic effects of contrast particles, hemodynamic changes, hypoxia and oxidative stress, apoptosis, inflammation, and immune responses. Prevention of CIN involves identifying the risk factors and taking appropriate measures to mitigate them. Currently, there is no definitive treatment for CIN, and treatment is mainly symptomatic, with supportive care being the mainstay. Experimental treatments such as renal replacement therapy, extracorporeal blood purification, and stem cell therapy are being investigated, but their clinical efficacy is yet to be established.
造影剂肾病(CIN)是一种众所周知的用于诊断和治疗目的的造影剂管理并发症。随着影像诊断和造影剂的广泛使用,CIN的发病率也在增加。CIN是一种病理状态,通常发生在造影剂暴露后48小时内,导致血清肌酐水平增加超过44 μ mol/L (0.5 mg/dL)或高于基线25%,或在暴露于造影剂后7天内血清肌酐水平增加超过基线水平的1.5倍,或在暴露于造影剂后至少6小时内尿量减少至低于0.5 mL/h。CIN的机制尚不完全清楚,但被认为与造影剂颗粒的直接肾毒性作用、血流动力学改变、缺氧和氧化应激、细胞凋亡、炎症和免疫反应有关。CIN的预防包括识别风险因素并采取适当措施减轻这些因素。目前,CIN没有明确的治疗方法,治疗主要是对症治疗,支持治疗是主要的。目前正在研究肾脏替代疗法、体外血液净化疗法、干细胞疗法等实验性治疗方法,但其临床疗效尚未确定。

Introduction: Kidney dysfunction, coagulopathy disorders, and lung involvement are the most common disorders caused by the COVID-19 virus. Objectives: This study aimed to investigate the correlation of lung involvement severity with kidney dysfunction and coagulopathy disorders in COVID-19 patients. Patients and Methods: This descriptive-analytical study was conducted on 97 patients with COVID-19 referred to Imam Reza hospital in Kermanshah from December 2020 to June 2021. Lung involvement severity, kidney function tests, and coagulation laboratory data were collected. Logistic regression test was conducted to explore the correlation between lung involvement with kidney dysfunction and coagulopathy disorders. Results: Out of 97 patients, 53 (54.6%) were male, with a mean age of 59.31 ± 16.44 years. The correlation between lung involvement severity with kidney function tests, including, blood urea nitrogen, serum creatinine, and coagulation factors, including prothrombin time (PT), partial thromboplastin time (PTT), and D-dimer, were significant (P > 0.05). Lung involvement severity significantly predicted kidney dysfunction and coagulopathy disorders. Conclusion: Lung involvement severity would be able to predict kidney dysfunction and coagulopathy disorders in patients with COVID-19.

Renal endocrine aspects of exercise-induced acute kidney injury (gym nephropathy) 运动性急性肾损伤(运动性肾病)的肾内分泌方面
Pub Date : 2023-01-01 DOI: 10.34172/jre.2023.25128

The important renal endocrine aspect implicated in gym nephropathy is the activation of the renin-angiotensin-aldosterone system (RAAS). Intense exercise can lead to increased sympathetic nervous system activity, resulting in the release of renin from the juxtaglomerular cells in the kidneys. Renin acts on angiotensinogen, leading to the generation of angiotensin II, a potent vasoconstrictor. Angiotensin II stimulates the secretion of aldosterone from the adrenal glands, which promotes sodium reabsorption and potassium excretion in the kidneys. The persistent activation of the RAAS in gym nephropathy may contribute to renal damage by causing vasoconstriction and promoting renal inflammation.
肾素-血管紧张素-醛固酮系统(RAAS)的激活是体育肾病中涉及的重要肾内分泌方面。剧烈运动可导致交感神经系统活动增加,导致肾素从肾脏肾小球旁细胞释放。肾素作用于血管紧张素原,导致血管紧张素II的产生,这是一种有效的血管收缩剂。血管紧张素II刺激肾上腺分泌醛固酮,从而促进肾内钠的重吸收和钾的排泄。在运动性肾病中,RAAS的持续激活可能通过引起血管收缩和促进肾脏炎症而导致肾脏损害。

Introduction: The correlation between hyperuricemia and chronic kidney disease (CKD) is an approval issue; this study aimed to evaluate the effect of allopurinol on serum uric acid levels in patients with diabetic nephropathy, with the review of randomized clinical trials (RCTs). Materials and Methods: This meta-analysis study was conducted on RCTs in diabetic nephropathy patients, which evaluated the effect of allopurinol on serum uric acid levels. Data were collected by searching international databases and Google Scholar search engines until May 2023. STATA 14 software and the random effects model were conducted to analyze the data. A P value less than 0.05 was considered significant. Results: In this study, five studies with a sample size of 942 patients were assessed. The effect of allopurinol on serum uric acid in comparison to the placebo group deduced that the standard mean difference between the allopurinol group and placebo group was -1.55 mg/dL, which was statistically significant (CI: -2.07 to -1.02). Conclusion: Allopurinol through its uric acid lowering effect would be beneficial for patients with diabetic nephropathy in preventing the progression of CKD. Registration: This study has been compiled based on the PRISMA checklist, and its protocol was registered on the PROSPERO website (ID: CRD42023412051).
导读:高尿酸血症与慢性肾脏疾病(CKD)之间的相关性是一个批准问题;本研究旨在评估别嘌呤醇对糖尿病肾病患者血清尿酸水平的影响,回顾随机临床试验(rct)。材料与方法:本荟萃分析研究在糖尿病肾病患者的随机对照试验中进行,评估别嘌呤醇对血清尿酸水平的影响。通过检索国际数据库和谷歌Scholar搜索引擎收集数据,截止到2023年5月。采用STATA 14软件和随机效应模型对数据进行分析。A P值小于0.05被认为是显著的。结果:本研究共纳入5项研究,共纳入942例患者。与安慰剂组相比,别嘌呤醇对血清尿酸的影响推断,别嘌呤醇组与安慰剂组的标准平均差异为-1.55 mg/dL,差异有统计学意义(CI: -2.07 ~ -1.02)。结论:别嘌呤醇通过其降尿酸作用对糖尿病肾病患者有预防CKD进展的作用。注册:本研究已根据PRISMA清单编制,其方案已在PROSPERO网站注册(ID: CRD42023412051)。

Nephroceuticals are natural or pharmacologically active compounds used to manage and even reverse certain kidney diseases. The term "nephroceuticals" is relatively new, although the study of utilizing natural or active compounds to manage kidney disease has been emerging for many years. Nephroceuticals have shown promise in supporting conventional therapies such as dialysis and kidney transplantation, and are purported to have fewer adverse effects compared to conventional chemical compounds.
肾药是天然或药理学活性化合物,用于管理甚至逆转某些肾脏疾病。尽管利用天然或活性化合物治疗肾脏疾病的研究已经出现多年,但术语“肾脏药物”相对较新。肾脏药物在支持透析和肾移植等传统疗法方面已经显示出前景,并且据称与传统化合物相比,副作用更少。
