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…

Oxidative stress, inflammation and cardiovascular disease in chronic renal failure

2008

Traditional risk factors such as hypertension, diabetes, dyslipidemia, obesity and metabolic syndrome, as well as additional nontraditional risk factors, can damage the kidney directly and by promoting intrarenal atherogenesis. Evidence indicates that increased oxidative stress and inflammation may mediate most of the effects of risk factors on the kidney. Clinical studies have demonstrated a relationship between oxidative stress and inflammatory biomarkers, and a few studies indicate an inverse correlation of oxidative stress biomarkers with estimated glomerular filtration rate (eGFR). Further, surrogate indexes of atherosclerosis such as intima-media thickness and aortic pulse wave veloci…

ENDOSCOPIC FINDINGS IN CHRONIC RENAL FAILURE: REVIEW OF LITERATURE

2012

Chronic kidney Disease (CKD) is associated with several gastrointestinal diseases, documented with endoscopy. we revisited internation experience about endoscopic pictures in these patients, analyzing only the pre-transplantation period. Gastritis, esophagitis, duodenitis, gastrointestinal bleeding, intestinal ischaemia, angiodysplasia and diverticula are the most common findings, but others are reported too. Every author has different data and percentages, and further studies are necessary to assess the relation between CKD and gastrointestinal diseases. CKD is often part of a multisystem damage, that makes the management of the patinet critical. The aim of this review is to consider patie…

USE OF INTRAPERITONEAL PTFE DUAL-MESH IN A GIANT INCISIONAL HERNIA AFTER RENAL TRANSPLANTATION: A CASE REPORT

2008

Objectives: We evaluated the incidence of incisional hernia after kidney transplantation, predisposing factors and the results of surgical repair of a giant incisional hernia by intraperitoneal PTFE dual mesh. Patients and methods: We report our experience about an incisional hernia in a 55 years male after renal transplantation treated with an intraperitoneal dual mesh prosthesis. The cause of incisional hernia was probably due to an urinoma for a total necrosis of distal graft ureter that needed to reopen in 2sd day post transplant with primary fascial approximation. Thirty days after transplantation we discovered a large incisional hernia that rapidly became monstrous with migration of o…

Urinary collagen cross-links to evaluate hyperparathyroidism in kidney transplant patients

2008

INTRODUCTION AND AIMS: One of most common complication following kidney transplantation is reappearance of hyperparathyroidism (HP) some months after normal serum levels. An early diagnosis represents the best prophylaxis measures to prevent worsening of osteodystrophy and potential damage to the graft and vascular tissue.The aim to our study was to evaluate, beyond the common HP markers, if the urinary cross-links of the collagen PYD (pyridinoline) and DPD (Deoxypyridinoline) are useful markers able to show increasing levels of parathormone. METHODS: We evaluated 50 stable kidney transplanted patients divided into 2 group (A: 38 pts and B: 12 pts) dependent on the type of their immunosuppr…

Two Patients With History of STEC-HUS, Posttransplant Recurrence and Complement Gene Mutations

2013

Hemolytic uremic syndrome (HUS) is a disease of microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. About 90% of cases are secondary to infections by Escherichia coli strains producing Shiga-like toxins (STEC-HUS), while 10% are associated with mutations in genes encoding proteins of complement system (aHUS). We describe two patients with a clinical history of STEC-HUS, who developed end-stage renal disease (ESRD) soon after disease onset. They received a kidney transplant but lost the graft for HUS recurrence, a complication more commonly observed in aHUS. Before planning a second renal transplantation, the two patients underwent genetic screening for aHUS-associat…

Ribonuclease H levels in herpes simplex virus-infected cells.

1980

Two forms of ribonuclease H (RNase H) have been identified both in uninfected and Herpes Simplex virus (HSV-)infected BHK cells. Identical RNase H species were detected in control- as well as in infected cells. RNase H I and II have not been found to be associated both with host cell DNA polymerase alpha and beta and HSV-induced DNA polymerase. Infection of BHK cells with HSV type 1 does not lead to a pronounced alteration of RNase H II activity but to an increase (3-fold) of the extractable RNase H I activity. RNase H I activity increases to a maximum between 8-10 hours p.i.; the bulk of HSV-DNA synthesis occurs between 6-8 hours p.i. From these experiments we draw the preliminary conclusi…
