Early serum creatinine changes and outcomes in patients admitted for acute heart failure: the cardio-renal syndrome revisited.

2017

Background: The changes in renal function that occurred in patients with acute decompensated heart failure (ADHF) are prevalent, and have multifactorial etiology and dissimilar prognosis. To what extent the prognostic role of such changes may vary according to the presence of renal insufficiency at admission is not clear. Accordingly, we sought to determine whether early creatinine changes (Cr) (admission to 48-72 hours) had an effect on 1-year mortality relative to the presence of renal insufficiency at admission. Methods: We included 705 consecutive patients admitted with the diagnosis of ADHF. Admission renal insufficiency was defined as serum creatinine 1.4mg/dl (A-RIcr) or estimated gl…

First case of Mediterranean spotted fever-associated rhabdomyolysis leading to fatal acute renal failure and encephalitis

2014

SummaryMediterranean spotted fever (MSF) is a tick-borne zoonosis caused by Rickettsia conorii. In Italy, about 400 cases are reported every year and nearly half of them occur in Sicily, which is one of the most endemic regions. Although MSF is mostly a self-limited disease characterized by fever, skin rash, and a dark eschar at the site of the tick bite called a ‘tache noire’, serious complications are described, mainly in adult patients. Nevertheless, severe forms of the disease with major morbidity and a higher mortality risk have been described. We report a fatal case of MSF complicated by rhabdomyolysis, acute renal failure, and encephalitis in an elderly woman.

Prevalence of biliary lithiasis in a Sicilian population of chronic renal failure patients.

2003

BACKGROUND The aim of this study was to evaluate the prevalence of biliary lithiasis (BL) and associated risk factors in a population of undialysed patients with chronic renal failure (CRF), and to compare these with findings we had obtained previously in chronic haemodialysis (HD) patients and in subjects from the general population located in the same geographic region. METHODS A total of 118 CRF patients on conservative treatment were included in the study. In all subjects, we measured several clinical and humoral parameters potentially correlated with BL. Liver and biliary tract ultrasonography was performed with a 3.5 MHz linear probe after at least 12 h of fasting. RESULTS The prevale…

Chronic renal failure: oxidative stress, endothelial dysfunction and wine.

2004

Atherosclerosis development is accelerated in chronic renal failure (CRF) and is the major cause of death in this clinical condition. An increased oxidative stress and an endothelial dysfunction, with their complex interrelationships, are relevant aspects of atherogenesis in CRF patients and might be targets for treatment. Many studies have underlined the cardiovascular protection provided by a moderate wine consumption. This beneficial effect is due to both alcohol and nonalcoholic components of wine including several phenolic molecules such as quercetin and resveratrol. Wine polyphenols have antioxidant properties and favorably influence endothelial function, in particular by stimulating …

Metalloprotease meprin beta in rat kidney: glomerular localization and differential expression in glomerulonephritis

2008

Meprin (EC 3.4.24.18) is an oligomeric metalloendopeptidase found in microvillar membranes of kidney proximal tubular epithelial cells. Here, we present the first report on the expression of meprin beta in rat glomerular epithelial cells and suggest a potential involvement in experimental glomerular disease. We detected meprin beta in glomeruli of immunostained rat kidney sections on the protein level and by quantitative RT-PCR of laser-capture microdissected glomeruli on the mRNA level. Using immuno-gold staining we identified the membrane of podocyte foot processes as the main site of meprin beta expression. The glomerular meprin beta expression pattern was altered in anti-Thy 1.1 and pas…

Imperative and Elective Indications for Nephron-Sparing Surgery for Renal Tumors: Long-Term Oncological Follow-Up

2010

INTRODUCTION: Nephron-sparing surgery (NSS) is mandatory for patients with renal tumors in both kidneys or in a solitary kidney in order to preserve renal function (imperative indication). NSS has also become the gold standard (elective indication) for small unilateral renal tumors (< 4 cm) with a normal contralateral kidney. We report the oncological long-term follow-up of NSS of our own series and discuss the results of the current literature. PATIENTS AND METHODS: From 1979 until 2006, a total of 851 patients was treated at our institu-tion by NSS. The mean tumor diameter was 3 cm (0.5-11 cm) for elective cases and 4.2 cm (1.2-11 cm) for imperative cases. The median follow-up for electiv…

A GIANT ANEURYSM OF PROPER HEPATIC ARTERY IN A CRYOGLOBULINEMIC PATIENT ON HEMODIALYSIS: A CASE REPORT.

2014

Introductrion. Hepatic artery aneurysms (HAAs) are unusual vascular lesions often associated with many different pathological conditions. Most of reported cases are described in association with connective tissue diseases, such as polyarteritis nodosa and systemic lupus erythematosus. Case report. We observed a 52-year-old man with hypertension and HCV-related cryoglobulinemia complicated by end stage renal disease on replacement therapy by hemodialysis. He was admitted to our hospital because of the worsening of blood pressure values (170/110 mmHg) associated to new onset abdominal pain. After an initial physical examination, that showed a periumbelical bruit associated to a pulsatile mass…

Circulating levels of molecular adhesion correlate with stage of renal disease and C-reactive protein in chronic kidney disease

2007

BACKGROUND: Patients with chronic renal failure (CRF) suffer from a series of complications linked to the atherosclerotic process in which the endothelial dysfunction mediated by the activation of some adhesion molecules plays an important role. This study aims to evaluate circulating levels of intercellular adhesion molecules-1 (ICAM-1) and vascular cell adhesion molecules-1 (VCAM-1) in patients with predialysis CRF, on maintenance hemodialysis (HD) and after kidney transplantation (KTx) and to correlate them with some inflammation and nutritional indexes. METHODS: Thirty two patients with predialysis CRF, 30 on maintenance HD, 36 after KTx and 28 subjects as a control group (C) were inclu…
