Treatment with essential amino acids in patients on chronic hemodialysis: a double blind cross-over study.
1978
Patients on chronic hemodialysis may suffer from a latent protein deficiency, and therapy with essential amino acids has been recommended. In a double blind cross-over study, 13 hemodialysis patients received orally 15.7 g of essential amino acids daily over a 3-month period. Patients were on a liberal diet, containing 1 g of protein per kilogram of body weight per day. Hemodialysis was adequate. Therapy resulted in an increase in urea, uric acid, C3 c complement factor and a fall in C4. Lysine levels increased and phenylalanine fell. Malnutrition could not account for the observed metabolic changes, which are more likely due to uremic metabolic disturbances. A liberal diet of 1 g of protei…
Circulating Levels of Adhesion Molecules in Chronic Kidney Disease Correlate with the Stage of Renal Disease and with C-Reactive Protein
2007
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.Thirty two patients with predialysis CRF, 30 on maintenance HD, 36 after KTx and 28 subjects as a control group (C) were included in this study. Cir…
Proteinuric effect of transcranial magnetic stimulation in healthy subjects and diabetic patients with stage 3-4 CKD
2013
BackgroundMany authors have investigated the numerous connections between the nervous system and kidneys, and recent literature has indicated that these similar systems are interconnected. Recent scientific works have shown that there is similarity between the cerebral cortex 'viscera representation' and the 'motor omunculus'. We studied the connection between the brain and kidney in vivo using repetitive transcranial magnetic stimulation (rTMS). Proteinuria and albuminuria were used as markers of renal response in patients with diabetes (DP) and in a group of healthy subjects (HSs) who received rTMS for 5 consecutive days.MethodsThe study population consists of the following four groups: G…
Tension-free hernia repair is associated with an increase in inflammatory response markers against the mesh.
2000
Abstract Background: The purpose of this study was to evaluate the involvement of inflammatory mediators in patients undergoing Lichtenstein tension-free hernioplasty (LH) using polypropylene prosthetic materials or conventional Bassini hernia repair (BH). Methods: Thirty patients male with unilateral inguinal hernia without complications or recurrence were included in this study. Randomly, patients underwent LH or BH. Peripheral venous bloods samples were collected 24 hours prior to surgery and then 6, 24, 48 and 168 hours postoperatively. Results: We present evidences that LH patients showed a higher increased serum level of fibrinogen, C-reactive protein, alpha-1-antitrypsin, and interle…
Urine cadmium levels and albuminuria in a general population from Spain: A gene-environment interaction analysis
2017
Background: The interaction of cadmium with genes involved in oxidative stress, cadmium metabolism and transport pathways on albuminuria can provide biological insight on the relationship between cadmium and albuminuria at low exposure levels. Objectives: We tested the hypothesis that specific genotypes in candidate genes may confer increased susceptibility to cadmium exposure. Methods: Cadmium exposure was estimated by inductively coupled plasma mass spectrometry (ICPMS) in urine from 1397 men and women aged 18–85years participating in the Hortega Study, a representative sample of a general population from Spain. Urine albumin was measured by automated nephelometric immunochemistry. Abnorm…
The prognostic value of sentinel lymph node micrometastases in patients with invasive breast carcinoma
2016
The prognostic value of sentinel lymph node micrometastases in invasive breast cancer patients is still widely debated. Even if, in the absence of unequivocal guidelines, the axillary lynphadenectomy is not still performed in the routine clinical care of these patients.We have retrospectively analyzed 746 patients with operable invasive breast cancer and clinically negative axillary lymph nodes. These patients underwent conservative surgery or total mastectomy with sentinel lymph node biopsy. Patients with micrometastases in the sentinel lymph node treated with axillary dissection has been checked and the involvement of the remaining lymph nodes analyzed. Patients with micrometastases in th…
Increased Levels of Elastase and α1-Antitrypsin in Sputum of Asthmatic Patients
1998
Asthma and chronic bronchitis are inflammatory diseases associated with remodeling of the extracellular matrix (ECM). Elastin, a major component of the ECM in the airways, has been previously found to be disrupted in asthma and chronic bronchitis. This study was aimed at evaluating whether elastin disruption might be associated with an imbalance between elastase (active and total) and alpha1-proteinase inhibitor (alpha1-PI), the main inhibitor of elastase. We measured elastase and alpha1-PI in induced sputum obtained from 16 control subjects, 10 healthy smokers, 19 asthmatic patients, and 10 chronic bronchitis patients. We also assessed the possible origin of elastase, evaluating its levels…
Hepatogenic differentiation of human mesenchymal stem cells from adipose tissue in comparison with bone marrow mesenchymal stem cells
2006
AIM: To investigate and compare the hepatogenic transdifferentiation of adipose tissue-derived stem cells (ADSC) and bone marrow-derived mesenchymal stem cells (BMSC) in vitro. Transdifferentiation of BMSC into hepatic cells in vivo has been described. Adipose tissue represents an accessible source of ADSC, with similar characteristics to BMSC. METHODS: BMSCs were obtained from patients undergoing total hip arthroplasty and ADSC from human adipose tissue obtained from lipectomy. Cells were grown in medium containing 15% human serum. Cultures were serum deprived for 2 d before cultivating under similar pro-hepatogenic conditions to those of liver development using a 2-step protocol with sequ…
Increase in Nocturnal Blood Pressure and Progression to Microalbuminuria in Type 1 Diabetes
2002
Patients with type 1 diabetes mellitus and microalbuminuria often have elevated blood pressure while they are asleep, but it is not known whether the elevation develops concomitantly with microalbuminuria or precedes it.We monitored 75 adolescents and young adults who had had type 1 diabetes with normal urinary albumin excretion and blood pressure for more than five years. Ambulatory blood-pressure monitoring was used to assess blood pressure at the initial evaluation and about two years later, at which time all subjects had normal urinary albumin excretion. Subsequently, subjects were monitored for the development of microalbuminuria.Microalbuminuria developed in 14 subjects, whereas the o…
The accuracy of sentinel lymph node biopsy in the treatment of multicentric invasive breast cancer using a subareolar injection of tracer.
2008
BACKGROUND: The aim of this study was to evaluate the feasibility and the accuracy of sentinel lymph node biopsy in multicentric breast cancer (MBC) performed by means of a subareolar (SA) injection of both 99Tc-labeled human albumin colloid and lymphazurin. METHODS: Between January 2002 and October 2007, 34 patients with MBC with clinically negative axilla underwent sentinel lymph node biopsy (SLNB) followed by total axillary node dissection (AD). Overall successful identification rate of SLN was 100%; there were no false negatives and overall accuracy rate was 100%. RESULTS: The mean number of sentinel lymph nodes (SLNs) identified was 1.8 +/- 0.88 (range = 1-4); the mean number of axilla…
