Is COVID‐19 infection more severe in kidney transplant recipients?
2021
International audience; There are no studies which have compared the risk of severe Covid-19 and related mortality between transplant recipients and non-transplant patients. We enrolled two groups of patients hospitalized for Covid-19, i.e., kidney transplant recipients from the French Registry of Solid Organ Transplant (n=306) and a single-center cohort of non-transplant patients (n=795). An analysis was performed among subgroups matched for age and risk factors for severe Covid-19 or mortality. Severe Covid-19 was defined as admission (or transfer) to an intensive care unit, need for mechanical ventilation, or death.Transplant recipients were younger and had more comorbidities compared to…
Consequences of analgesics use in early pregnancy: Results of tests on mice.
2019
International audience; Self-medication during pregnancy continues to be an issue in developing countries due topoor medical education. The most commonly used drugs are analgesics, mainlyacetaminophen (paracetamol, APAP) and, to a lesser extent, ketoprofen (KPF). The aim of thestudy was to establish whether there are consequences of accidental use of these two drugsduring early embryogenesis. The experimental study was performed on 30 pregnant whitemice, divided into three groups: a first group to which APAP was administered, a secondgroup to which KPF was administered, and group 3 as a control group. At delivery, the babymice were examined, and after their first parturition, they were take…
Adsorption of methotrexate and calcium leucovorin onto cholestyramine in vitro.
2003
Abstract Methotrexate (MTX), an antimetabolite of folic acid, is a drug widely used in the treatment of different types of cancer. When high doses are administered, it is necessary to interrupt its action by administering calcium leucovorin (CaL). The main pathway of MTX and CaL elimination in humans occurs through the kidney, but about 10% is excreted in the faeces via the bile. Drugs, foods and sorbents in intestinal lumen modify MTX and CaL reabsorption. Individual and simultaneous studies on the adsorption of MTX and CaL from aqueous phosphate buffer by cholestyramine were carried out in order to calculate the adsorption process of MTX and CaL to cholestyramine, and to characterize the …
GLP-1 receptor agonists and renal outcomes in patients with diabetes mellitus type 2 and diabetic kidney disease: state of the art
2022
ABSTRACT Background Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are highly effective in improving glycaemic control either as monotherapy or in combination with other hypoglycaemic drugs, and have low incidence of side effects, such as hypoglycaemia, nausea and weight gain, thus increasing patients' adherence to therapy. Methods In this review we report the most recent studies demonstrating the beneficial effects of GLP-1RAs on renal outcomes, and also discuss the direct and indirect mechanisms through which they confer kidney protection. Finally, we discuss the metabolic and anti-inflammatory effects of GLP-1RAs in diabetic patients with COVID-19 disease. Results GLP-1RAs have a n…
Impact of Obesity in Kidney Diseases.
2021
The clinical consequences of obesity on the kidneys, with or without metabolic abnormalities, involve both renal function and structures. The mechanisms linking obesity and renal damage are well understood, including several effector mechanisms with interconnected pathways. Higher prevalence of urinary albumin excretion, sub-nephrotic syndrome, nephrolithiasis, increased risk of developing CKD, and progression to ESKD have been identified as being associated with obesity and having a relevant clinical impact. Moreover, renal replacement therapy and kidney transplantation are also influenced by obesity. Losing weight is key in limiting the impact that obesity produces on the kidneys by reduc…
Relationship between mild to moderate renal dysfunction and obstructive sleep apnea: Data from the European sleep apnea database
2013
The relationship between severity of obstructive sleep apnea (OSA) and kidney function was investigated in the European Sleep Apnea Database (ESADA), where clinical, sleep, and biochemical data of patients studied for suspected OSA in 24 sleep centres of 17 European countries are stored. After excluding patients with missing data or extremely high/low creatinine values, data from 8112 subjects (2328 female) with creatinine values ranging between 0.5 and 2.0 mg% were analyzed. Estimated glomerular filtration rate (eGFR) was obtained with the Modified Diet in Renal Disease (MDRD) equation. Patients were subdivided into two groups: group 1 (n = 3709) studied by full polysomnography; group 2 (n…
High Plasma Angiopoietin-2 Levels Predict the Need to Initiate Dialysis within Two Years in Patients with Chronic Kidney Disease
2023
Volume status, congestion, endothelial activation, and injury all play roles in glomerular filtration rate (GFR) decline. In this study, we aimed to determine whether the plasma endothelial and overhydration markers could serve as independent predictors for dialysis initiation in patients with chronic kidney disease (CKD) 3b-5 (GFR < 45 mL/min/1.72 m2) and preserved ejection fraction. A prospective, observational study in a single academic center was conducted from March 2019 to March 2022. Plasma levels of angiopoietin (Ang)-2, Vascular Endothelial Growth Factor-C (VEGF-C), Vascular Cell Adhesion Molecule-1 (VCAM-1), Copeptin (CPP), beta-trace protein (BTP), brain natriuretic peptide (BNP)…
Association of Oxidative Stress with Aortic Stiffness in Hypertensive Patients with Chronic Kidney Disease
2011
Several studies have consistently demonstrated that arterial stiffness becomes progressively worse as CKD progresses and a negative correlation of oxidative stress with renal function has been described. There is also sound experimental evidence indicating that oxidative stress is involved in atherogenesis. The contribution of oxidative stress to aortic stiffness is less clear. Aim: To analyse the relationship between plasma levels of 8-ISO-prostaglandin F2alpha (8-ISOPGF2alpha), an index of lipid peroxidation, considered a reliable biomarker of oxidative stress, and aortic stiffness in a group of hypertensive patients with chronic kidney disease. Methods: We enrolled 126 hypertensive patie…
Genetic profile and immunohistochemical study of clear cell renal carcinoma: Pathological-anatomical correlation and prognosis.
2021
Abstract Introduction Renal cell carcinoma (RCC) accounts for 2–3% of all tumors being the most frequent solid lesion in the kidney. Objective To determine what genetic alterations and immunohistochemical (IHC) of clear cell renal carcinoma (ccRCC) are associated with prognosis and tumor aggressiveness. Patients and Methods Experimental analytical study with 57 patients who underwent radical and partial nephrectomy between 2005 and 2011, all with diagnosis of ccRCC and minimum post-operative follow-up of 36 months. The pathological study included IHC determination of biomarkers associated (CAIX, CAM 5.2, CD10, c-erbB-2, EGFR, HIF-1a, Ki67, MDM2, PAX-2 y 8, p53, survivin and VEGFR 1 and 2). …
