Kynurenine and Neopterin in Chronic Glomerulonephritis

1999

The results of our clinical observations of 102 patients with chronic glomerulonephritis with normal renal function have shown that hyperkynureninemia in 22,5% of patients develops in cases of pyridoxal-5-phosphate deficiency (hyperkynureninemia after peroral L-tryptophan load), but in 14,8% of patients through the stimulation of the cellular immune system (hyperkynureninemia at fasting state, increase of serum neopterin concentration). In all 20 patients with chronic renal failure hyperkynureninemia develops due to decreased renal function (increased serum kynurenine, neopterin and creatinine concentrations). Therefore, L-tryptophan peroral loading test with the determination of serum conc…

Polymorphonuclear leukocyte integrins in chronic renal failure

2005

Patients with chronic renal failure (CRF), in comparison with general population, show a higher cardiovascular mortality, not fully explained by the "traditional" risk factors. Among the new factors that have been hypothesized, leukocytes might play an important role. In a group of patients with mild CRF we determined, at baseline and after in vitro activation with 4-phorbol-12-myristate-13-acetate (PMA) and N-formyl-methionyl-leucyl-phenylalanine (fMLP), the polymorphonuclear leukocytes (PMN) beta2-integrin pattern (CD11a, CD11b, CD11c and CD18) by using indirect immunofluorescence with a flow cytometer. At baseline we observed an increase in the phenotypical expression of CD11b, CD11c and…

Severe Mediterranean spotted fever complicated by acute renal failure and herpetic oesophagitis

2010

Mediterranean spotted fever (MSF) is a tick-borne disease caused by Rickettsia conorii. Recently, complicated cases have been more frequently reported, even in previously healthy patients. We describe a case of severe MSF complicated by acute renal failure and associated with herpetic oesophagitis. Acyclovir therapy resulted in remission of oesophageal symptoms within 48 h.

Pulse wave velocity differs between ulcerative colitis and chronic kidney disease

2017

Background: We hypothesized that a reversal of the physiological stiffness gradient, previously reported in end-stage renal disease, begins in the early stages of chronic kidney disease (CKD) and that chronic inflammation produces a different arterial phenotype in patients with ulcerative colitis (UC). Objectives: To assess the extent of arterial stiffening in the central (carotid-femoral pulse wave velocity, cf.-PWV) and peripheral arteries (carotid-radial pulse wave velocity, cr-PWV) and to explore the determinants of the stiffness gradient in UC and in CKD. Methods: We enrolled 45 patients with UC, 45 patients with stage 3-4 CKD and 45 matched controls. Results: Despite the comparable cf…

Chronic renal failure: leukocyte rheology and polymorphonuclear cytosolic Ca2+ concentration.

2000

In a group of subjects with chronic renal failure (CRF), we evaluated the leukocyte rheological activity, expressed as the filtration rate, the polymorphonuclear (PMN) membrane fluidity and the PMN cytosolic Ca2+ content. Using the St. George's Filtrometer, we determined the filtration rate of unfractionated, mononuclear and PMN leukocytes. Using the fluorescent probe 1.4-(trimethylamino)-phenyl-4-phenyl-hexatriene (TMA-DPH), we examined the PMN membrane fluidity and, using the Fura 2-AM, the PMN cytosolic Ca2+ content. From the results obtained, it is evident that only the initial relative flow rate of unfractionated leukocytes was significantly reduced in subjects with CRF, while the filt…

Elastase, myeloperoxidase, nitric oxide metabolites and oxidative status in subjects with clinical stable chronic renal failure on conservative treat…

2009

We evaluated, in a group of 41 CRF undialyzed subjects (29 men and 12 women, mean age 64.1 +/- 11.3 years), some parameters that reflect leukocyte activation (elastase, myeloperoxidase - MPO), plasma NO metabolites (NO(x)) and the oxidative status (lipid peroxidation expressed as thiobarbituric acid-reactive substances (TBARS) and total antioxidant status (TAS). Elastase was determined, on plasma separated from fasting venous blood, as elastase/alpha1-proteinase inhibitor complex. MPO was evaluated employing the Myeloperoxidase ELISA kit. The NO production was evaluated by a micromethod. The oxidation of polyunsaturated fatty acids was evaluated in plasma by detection of the thiobarbituric …

A case of naturally evolving gout in an elderly man

2012

Gout is a common disorder in adults that can lead to severe organ decline, disability and impaired quality of life due to the formation of periarticular tophi. We report a case of massive tophaceous gout in a 78-year-old man with a 16-year-long history of untreated disease. The patient gradually became disabled, his renal function deteriorated, and he finally died of sepsis. Our case demonstrates that chronic gout not only affects the joints, but is also associated with organ function decline and can, even nowadays, lead to death. © 2011 Elsevier Ireland Ltd.
