Background And Objectives: The importance of hematological parameters has started to be explored with increased interest in many fields lately, with different studies finding an association between those parameters and inflammatory status, atherosclerosis, comorbidities, malnutrition, neoplasia and even a faster progression of chronic kidney disease (CKD). On the other hand, CKD itself presents as an inflammatory condition, in which a lot of pathways are modified and the response to an infectious agent could be less than expected. Regarding the latter aspect, in this study we aim to explore the differences between the hematologic response during a lower versus upper urinary tract infection in patients with CKD.

Also, the mortality of septic-AKI can reach 70% in critically-ill patients. These sole facts can give rise to a question: is there something we do not understand yet? Currently, there are no specific therapies for septic AKI and the treatment aims only to maintain the mean arterial pressure over 65mmHg by ensuring a good fluid resuscitation and by using vasopressors, along with antibiotics.

Arginine auxotrophy in ADPKD induces cell hyperproliferation, blocking the normal differentiation of renal tube cells and causing cyst formation. We explored the L-arginine (Arg)-nitric oxide (NO) molecular pathway in ADPKD, a multisystemic arginine auxotrophe disease.

Cellular accumulation of NO and reactive nitrogen species in many types of tumour cells is expressed by an increased susceptibility to oxidative stress in the tumour microenvironment. Clear cell renal cell carcinoma (ccRCC) is a progressive metabolic disease in which tumour cells can adapt to metabolic reprogramming to enhance NO production in the tumour space.

Because chronic kidney disease is very frequent, affecting 10% of the population, our study aims to explore the impact that infectious events have on its progression. : This is a retrospective, observational study based on a cohort of 238 dialyzed patients from the Nephrology Clinic of "Dr.

The aim of the study was to determine the pathophysiological mechanisms of the oxidative stress-related damage and molecular mechanisms to counteract oxidative stimuli in lupus nephritis. Our study included 38 SLE patients with lupus nephritis (LN group), 44 SLE patients without renal impairment (non-LN group) and 40 healthy volunteers as control group.

Material And Methods: A case-control study was developed and included 109 patients with SLE with or without renal impairment, 32 patients with IgA nephropathy and 60 healthy volunteers, clinically and paraclinically monitored. The following parameters were evaluated in volunteers serum: total sialic acid (TSA), orosomucoids, lipid bound sialic acid (LSA), interleukin-6 (IL-6), soluble factors IL-6R, gp130, anti -GM1, -GM2, -GM3, -GD1a, -GD1b, -GT1b, -GQ1b antigangliosides antibodies of IgG and IgM type.
Objectives: The aims of this study were to evaluate the pharmacokinetics (PK) of gadopiclenol, a new macrocyclic gadolinium based-contrast agent, in subjects with impaired renal function, and to assess its dialysability in subjects with end-stage renal disease (ESRD).
Methods And Materials: This 2-center, open-label, phase 1 study included 5 successive cohorts of 8 adult subjects: healthy subjects (cohort 1), subjects with mild (cohort 2), moderate (cohort 3), severe (cohort 4) renal impairment, or ESRD (cohort 5), who received a single intravenous injection of gadopiclenol (0.1 mmol/kg).
Posttranslational modifications are dynamic enzymatic-mediated processes, regulated in time and space, associated with cancer development. We aimed to evaluate the significance of posttranslational modifications in the pathogenesis of clear cell renal cell carcinoma. The authors developed a prospective, observational study during a period of three years and included 55 patients with localized renal cell carcinoma and 30 heathy subjects.

Kidney damage is represented in most cases by glomerulopathies, which include membranous nephropathy, membranoproliferative glomerulonephritis (MPGN), IgA nephropathy, focal and segmental glomerulosclerosis and diabetic nephropathy. We conducted a retrospective study on 639 patients diagnosed with chronic viral hepatitis B and C and different renal diseases.

Methods: Chronic kidney disease was defined according to the KDIGO 2012 criteria as an estimated glomerular filtration rate <60 mL/min/1.73 m(2) and/or urinary albumin-to-creatinine ratio ≥30 mg/g.
Gangliosides are multifunctional molecules, abundantly expressed in renal cell membrane but also in sera of patients with renal disease. The aim of this study was to quantify the serum levels of sialic acid-ganglioside in patients diagnosed with diabetes for an eventual biomarker stratification of patients with renal complications. We included 35 diabetic patients without metabolic complications, 35 patients with diabetic nephropathy, 35 non-diabetic individuals.

This epithelial cell proliferation may get features of either pseudocrescent or tubular profiles. Our case of collapsing focal segmental glomerulosclerosis has been ultrastructurally investigated concerning the proliferating epithelial cell type: parietal versus visceral.

To get more information on the histogenetic origin of these tumors, a comprehensive ultrastructural investigation on the human renal capsule has been done on kidney biopsy samples performed for nephropathologic diagnosis. The human renal capsule ultrastructure is similar to that of the mammalian renal capsule.
