Clinical and molecular spectrum of renal malformations in Kabuki syndrome.
2013
International audience; OBJECTIVE: To determine the frequency and types of renal malformations, and to evaluate renal function in a cohort of patients with Kabuki syndrome (KS). STUDY DESIGN: Renal ultrasound scans and plasma creatinine measurements were collected from a French cohort of 94 patients with genotyped KS. Renal function was evaluated based on the estimated glomerular filtration rate. A genotype-phenotype study was conducted for renal and urinary tract malformations. RESULTS: Renal malformations were present in 22% of cases, and urinary tract anomalies were present in 15%. Renal malformations were observed in 28% of the MLL2 mutation-positive group and in 0% of the MLL2 mutation…
Congenital Solitary Kidney in Children: Size Matters
2016
We assessed renal function outcome in children with congenital solitary kidney and evaluated prognostic risk factors.We retrospectively studied the clinical charts of 210 children presenting with congenital solitary kidney at 2 pediatric nephrology and 5 pediatric units between January 2009 and October 2012. Children 0 to 18 years old with a congenital solitary kidney confirmed by scintigraphy were enrolled. Of the patients 146 were suitable for analysis. Median followup was 4.6 years. Primary outcome was decreased estimated glomerular filtration rate, and secondary outcome was occurrence of proteinuria and/or systemic hypertension. Primary outcome-free survival analysis was performed, incl…
GDF-15 predicts cardiovascular events in acute chest pain patients
2017
Background Treatment of patients presenting with possible acute myocardial infarction (AMI) is based on timely diagnosis and proper risk stratification aided by biomarkers. We aimed at evaluating the predictive value of GDF-15 in patients presenting with symptoms suggestive of AMI. Methods Consecutive patients presenting with suspected AMI were enrolled in three study centers. Cardiovascular events were assessed during a follow-up period of 6 months with a combined endpoint of death or MI. Results From the 1818 enrolled patients (m/f = 1208/610), 413 (22.7%) had an acute MI and 63 patients reached the combined endpoint. Patients with MI and patients with adverse outcome had higher GDF-15 le…
Cardiac and renal dysfunction is associated with progressive hearing loss in patients with Fabry disease.
2017
Background Fabry disease (FD) is an X-linked recessive hereditary lysosomal storage disorder which results in the accumulation of globotriaosylceramid (Gb3) in tissues of kidney and heart as well as central and peripheral nervous system. Besides prominent renal and cardiac organ involvement, cochlear symptoms like high-frequency hearing loss and tinnitus are frequently found with yet no comprehensive data available in the literature. Objective To examine hearing loss in patients with FD depending on cardiac and renal function. Material and methods Single-center study with 68 FD patients enrolled between 2012 and 2016 at the Department of Oto-Rhino-Laryngology, Plastic, Aesthetic and Reconst…
Association between uric acid and renal function in hypertensive patients: which role for systemic vascular involvement?
2016
The role of systemic vascular involvement in mediating the association between serum uric acid (SUA) and renal function in hypertension has not been explored. Main purpose of our study was to investigate whether morphofunctional vascular changes, assessed as carotid intima-media thickness (cIMT) and aortic pulse wave velocity (aPWV), might mediate the association between SUA and renal damage. We enrolled 523 hypertensive subjects with or without chronic kidney disease and divided population into tertiles of SUA based on sex-specific cutoff values. cIMT and aPWV were higher in uppermost SUA-tertile patients when compared to those in the lowest ones (all P < .001). Uricemia strongly correlate…
Liraglutide and Renal Outcomes in Type 2 Diabetes.
2017
BACKGROUND: In a randomized, controlled trial that compared liraglutide, a glucagon-like peptide 1 analogue, with placebo in patients with type 2 diabetes and high cardiovascular risk who were receiving usual care, we found that liraglutide resulted in lower risks of the primary end point (nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes) and death. However, the long-term effects of liraglutide on renal outcomes in patients with type 2 diabetes are unknown. METHODS: We report the prespecified secondary renal outcomes of that randomized, controlled trial in which patients were assigned to receive liraglutide or placebo. The secondary renal outcome was a co…
Relationship between kidney findings and systemic vascular damage in elderly hypertensive patients without overt cardiovascular disease
2017
Few studies have investigated the influence of age on the relationships between systemic vascular damage, kidney dysfunction, and intrarenal hemodynamic changes in patients with hypertension without overt cardiovascular disease. The authors enrolled 126 elderly patients with hypertension (aged ≥65 years) and 350 nonelderly patients with hypertension (aged <65 years). Carotid intima‐media thickness, renal resistive index, and aortic pulse wave velocity were performed in all patients. Elderly patients with hypertension had lower estimated glomerular filtration rates and higher albuminuria, renal resistive index, carotid intima‐media thickness, and aortic pulse wave velocity compared with none…
Association Between Uric Acid and Renal Hemodynamics: Pathophysiological Implications for Renal Damage in Hypertensive Patients
2016
The role of vascular renal changes in mediating the association between serum uric acid (SUA) and renal damage is unclear. The purposes of this study were to investigate the relationship between SUA and renal resistive index (RRI), assessed by duplex Doppler ultrasonography, and to assess whether hemodynamic renal changes may explain the association between SUA and renal damage in hypertensive patients. A total of 530 hypertensive patients with and without chronic kidney disease were enrolled and divided into SUA tertiles based on sex-specific cutoff values. RRI and albuminuria were greater and glomerular filtration rate (GFR) was lower in the uppermost SUA tertile patients when compared wi…
Brain and kidney, victims of atrial microembolism in elderly hospitalized patients? Data from the REPOSI study
2015
Abstract Background It is well known that atrial fibrillation (AF) and chronic kidney disease (CKD) are associated with a higher risk of stroke, and new evidence links AF to cognitive impairment, independently from an overt stroke (CI). Our aim was to investigate, assuming an underlying role of atrial microembolism, the impact of CI and CKD in elderly hospitalized patients with AF. Methods We retrospectively analyzed the data collected on elderly patients in 66 Italian hospitals, in the frame of the REPOSI project. We analyzed the clinical characteristics of patients with AF and different degrees of CI. Multivariate logistic analysis was used to explore the relationship between variables an…
Pilot study of safety and efficacy of polyprenols in combination with coenzyme Q10 in patients with statin-induced myopathy
2016
Background and objective: Statin-induced myopathy (SIM) has been partially attributed to deficiency of dolichol and coenzyme Q10 (CoQ10). We aimed to test the safety and efficacy of plant polyprenols in combination with CoQ10 for alleviation of SIM. Materials and methods: In an open-label, one-center prospective pilot study patients with SIM received conifer-tree needle polyprenols (4 mg/day) and CoQ10 (100 mg/day) for 8 weeks. Symptoms and safety were evaluated according to symptom severity score (0–10), creatine kinase (CK) levels, exercise test, dynamometry, complete blood count, clinical biochemistry and electrocardiography. Results: Of the 14 patients, 11 completed the study per protoc…
