Creatine renal function

BACKGROUND: In this study, we analyzed intestinal flora in an experimental mouse model of chronic kidney disease (CKD) and investigated whether oral supplementation with probiotic Lactobacillus rhamnosus GG could slow the decline in renal function and inflammatory status of mice with CKD. METHODS: We surgically induced chronic kidney disease in C57BL/6J male mice aged 8-9 weeks. We used dual-stage 5/6 nephrectomy for this, while the mock group underwent a mock procedure...

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a multifactorial condition with metabolic-related complications, such as diabetic nephropathy and chronic renal disorder, which are the leading cause of renal transplant globally. Protective effects of histone deacetylase (HDAC) inhibitors (HDACi) have been documented in metabolic-linked pathologies. Nonetheless, the current study investigated the restorative role of HDACi, butyrate in experimental PCOS-induced renal disorder. MATERIALS AND METHODS: Female Wistar rats (8-week-old) were divided into groups; control, butyrate-treated, letrozole and letrozole + butyrate-treated groups...

BACKGROUND: Protocol biopsies are performed to detect subclinical pathologies that may lead to future graft dysfunction. However, they are not routinely performed interventions in every transplant center. There is no established regimen for performing them. PURPOSE: The study aimed to evaluate if protocol biopsies can improve long-term patient outcomes after detecting early disorders and modifying treatment. MATERIAL AND METHODS: Our observational study included 61 patients who underwent protocol biopsy 12 months after the transplantation...

INTRODUCTION: Several reports have noted that severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) induced lymphopenia in coronavirus disease 2019 (COVID-19) patients. However, the clinical significance of lymphopenia remains unclear. The objective of this study was to analyze the association between lymphopenia at an early stage and the prognosis of COVID-19 patients. MATERIAL AND METHODS: All 192 hospitalized patients with COVID-19 were enrolled. Demographic data and clinical characteristics were collected and patient's prognosis was followed up...

Phenotypic age acceleration (PAA) is a sensitive marker of biological aging. Circulating methylmalonic acid (MMA) is a novel biomarker of mitochondrial dysfunction and has been associated with age-related disorders. Our study aimed to investigate to what extent circulating MMA was associated with PAA, and whether the association was independent of vitamin B12 status and renal function in the general population. We analyzed cross-sectional data from 13,023 participants across a wide age range (mean age: 38.9 years, range: 12 - 85 years, 51...

Introduction Anabolic androgenic steroids (AAS) and diet supplements (DS) are frequently used by bodybuilders. In this specific group, increased muscle mass, the acute effects of exercise, and the use of creatine may affect the creatinine-based estimated glomerular filtration rate (eGFRcr), potentially leading to an underestimation of the GFR. Cystatin C equations offer a more accurate prediction of GFR that is independent of muscle mass. We aimed to assess the renal functions of bodybuilders who use both AAS+DS, as well as those who only use DS, by calculating the GFR based on cystatin C (eGFRcys) and also using a combination of cystatin C and creatinine (eGFRcys/cr)...

Acute kidney injury (AKI) is the main cause of death from Bothrops snakebite. Although many studies have investigated the nephrotoxicity induced by other Bothrops species, no study has assessed the renal alterations induced by intramuscular (i.m.) injection of Bothrops leucurus venom. In this study, we evaluated the nephrotoxicity induced by B. leucurus venom by analyzing renal function and histology. Wistar rats were submitted to i. m. injection of B. leucurus venom or saline and divided into two groups: Control group (C), rats submitted to i...

BACKGROUND: Thyroid hormone synthesis is a complex process in the human body. Although the thyroid gland is essential for thyroid hormone synthesis, skeletal muscles also have crucial roles in thyroid hormone metabolism due to the deiodinase activities of the muscle cells. Hypothyroidism-related myopathy is a well-known entity. However, systemic effects of acute myopathies, such as rhabdomyolysis, on thyroid hormone metabolism have not to date been fully clarified. METHODS: Fifty-three earthquake victims were evaluated retrospectively...

Infantile systemic hyalinosis is a very rare fatal autosomal recessive genetic disorder with a mutation in capillary morphogenesis gene-2- CMG2 /Human anthrax toxin-2 ANTXR2 resulting in spindle cell proliferation, altered collagen metabolism along with extensive deposition of hyaline material in the skin and several tissues. To date only a few cases have been reported in the literature, hence we reported this series. This study is a retrospective chart review of infants diagnosed with infantile systemic hyalinosis from January 2015 through December 2020 at a tertiary care children's hospital in South India...

BACKGROUND: Renal dysfunction is one of the adverse effects observed in methamphetamine (MET) or tramadol abusers. In this study, we aimed to review articles involving intoxication with MET or tramadol to assess the occurrence of renal dysfunction. METHODS: Two researchers systematically searched PubMed, Scopus, Web of Sciences, and Google Scholar databases from 2000 to 2022. All articles that assessed renal function indexes including creatine, Blood Urea Nitrogen (BUN), and Creatine phosphokinase (CPK) in MET and tramadol intoxication at the time of admission in hospitals were included...

Cardiovascular complications of diabetes and obesity remain a major cause for morbidity and mortality worldwide. Despite significant advances in the pharmacotherapy of metabolic disease, the available approaches do not prevent or slow the progression of complications. Moreover, a majority of patients present with significant vascular involvement at early stages of dysfunction prior to overt metabolic changes. The lack of disease-modifying therapies affects millions of patients globally, causing a massive economic burden due to these complications...

OBJECTIVE: Among fibrates as triglyceride-lowering agents, bezafibrate and fenofibrate are predominantly renally excreted, while pemafibrate is mainly hepatically metabolized and biliary excreted. To elucidate possible different properties among fibrates, this retrospective observational study examined the changes in clinical laboratory parameters, including indices of renal function and glucose metabolism, in cases of switching from bezafibrate to pemafibrate. MATERIALS AND METHODS: In 93 patients with hypertriglyceridemia, the average values of laboratory parameters including serum creatinine, estimated glomerular filtration rate (eGFR), plasma glucose, and hemoglobin A1c on respective two occasions before and after switching from bezafibrate to pemafibrate were evaluated...

BACKGROUND Tricyclic antidepressant (TCA) drugs are a common cause of fatal poisoning because of their cardiotoxic and arrhythmogenic effects. Classic supportive management includes sodium bicarbonate, gastrointestinal chelating agents, and vasopressors. Recently, intravenous lipid emulsion (supported by a low evidence level) has also been used. CASE REPORT We report the case of a 55-year-old woman admitted to our Intensive Care Unit (ICU) with acute imipramine self-poisoning. She arrived at the emergency department 7 hours after imipramine ingestion; she had severe rhabdomyolysis upon admission, with creatine phosphokinase levels at about 52 500 IU/L (normal, <200 IU/L)...

Acute renal failure with severe loin pain and patchy renal ischemia after anaerobic exercise (ALPE) is a rare cause of exertional acute kidney injury. The proposed mechanism of injury in ALPE is renovascular spasm, in the setting of oxidative stress and muscular damage, which creates a characteristic wedge-shaped infarction pattern on delayed imaging. Patients present with nausea, vomiting, loin or abdominal pain, and fatigue within 1-2 days of anaerobic exercise, associated with an acute rise in serum creatinine, which generally plateaus within 3 days...

BACKGROUND: The relationship between perfusion index (PI) and organ dysfunction in patients in the intensive care unit (ICU) is not clear. This study aimed to explore the relationship between PI and renal function in the perioperative critical care setting and evaluate the predictive efficiency of PI on patients with acute kidney injury (AKI) in the ICU. METHODS: This retrospective analysis involved 12,979 patients who had undergone an operation and were admitted to the ICU in Peking Union Medical College Hospital from January 2014 to December 2019...

Although widely used in medicine, separation technology, and other fields, the effects of cyclodextrins on the activities of phosphoryl transfer enzymes have not been previously evaluated. In vivo studies evaluated the function of cyclodextrins as active compounds. Despite the use of cyclodextrins as active compounds, the effects of cyclodextrins on hepatic and renal tissues remain to be fully elucidated. The primary objective of this study was to evaluate the effects of β- cyclodextrins, methyl-β-cyclodextrin (M-β- cyclodextrins), and (2-hydroxypropyl)-β-cyclodextrin (HP-β-cyclodextrins) on enzyme activities regulating the maintenance of energy homeostasis in the kidney and liver tissues in relation to toxicity...

BACKGROUND AND OBJECTIVE: Caused by shared genetic risk factors and similar neuropsychological symptoms, bipolar disorder (BD) and major depressive disorder (MDD) are at high risk of misdiagnosis, which is associated with ineffective treatment and worsening of outcomes. We aimed to develop a machine learning (ML)-based diagnostic system, based on electronic medical records (EMR) data, to mimic the clinical reasoning of human physicians to differentiate MDD and BD (especially BD depressive episodes) patients about to be admitted to a hospital and, hence, reduce the misdiagnosis of BD as MDD on admission...

We present a case report of a non-ST segment elevation myocardial infarction (NSTEMI) occurring in an 89-year-old male with severe rhabdomyolysis and COVID-19 infection. The patient had a complex medical history, including non-ischemic cardiomyopathy, sinus bradycardia status post permanent pacemaker placement, and multiple comorbidities. He presented to the emergency department after a mechanical fall and was found to be COVID-19 positive. Despite the absence of typical symptoms, the patient's elevated troponin levels and electrocardiogram findings indicated NSTEMI...

BACKGROUND: Rhabdomyolysis-induced acute kidney injury is a serious condition that can progress to acute renal failure if not promptly identified and treated. Rhabdomyolysis occurs when serum creatine kinase levels approach > 1000 U/L (five times the normal upper limit). The chance of acute kidney injury increases as the levels of creatine kinase increase. Although Huntington's disease is associated with muscle atrophy, elevated baseline creatine kinase levels in these patients have not been routinely reported...

BACKGROUND: Kidney transplantation (KT) and end-stage renal disease (ESRD) requiring hemodialysis (HD) increase the incidence of morbidity and mortality associated with coronavirus disease 2019 (COVID-19) infection. The COVID-19 pandemic has had a negative effect on the psychological well-being of COVID-19 patients, especially those with a high-risk of infectious complications. The prevalence of anxiety and depression is known to be higher in ESRD patients undergoing HD than in the general population...
