Elderly dialysis patients: analysis of factors affecting long-term survival in 4-year prospective observation

Purpose To assess factors influencing the long-term survival of elderly dialysis patients. Methods The study group consisted of 51 prevalent dialysis patients aged over 70 years (32 F and 19 M, all caucasians), who had been on a chronic hemodialysis (27) or peritoneal dialysis program (24) for at least 2 months; median age was 77 years, median time on dialysis before inclusion was ...

Low concentration of heparin used for permanent catheters canal locking is effective and diminishes the risk of bleeding

Purpose There is an increasing number of patients being dialyzed with permanent catheters (PC). In the majority of cases, heparin is used to maintain PC patency. This practice causes clotting disturbances due to heparin leakage and may predispose the patient to bleeding episodes. It has not been well studied whether lowering heparin concentration for canal locking decreases ...

Histological heterogeneity of glomerular segmental lesions in focal segmental glomerulosclerosis

Focal segmental glomerulosclerosis (FSGS) involves considerable histological heterogeneity in terms of location and quality of the glomerular segmental lesions. The present study investigated the heterogeneity of segmental lesions in each variant of FSGS, determined by the Columbia classification, and its clinical relevance. All glomerular segmental lesions of 80 cases of primary ...

Changes in interstitial cell of Cajal-like cells density in congenital ureteropelvic junction obstruction

Purpose The authors examined the number of interstitial cells of Cajal-like cells (ICC-LCs) in obstructed ureteropelvic junction (UPJ) in comparison with normal UPJ specimens and age-related changes. Materials and methods A total of 20 human formalin fixed, paraffin-embedded specimens of intrinsic UPJO from children at the mean age of 8.1 years (age range: 8 months–16.8 years) and ...

Organ-sparing surgery of the bilateral testicular large cell calcifying sertoli cell tumor in patient with atypical Peutz–Jeghers syndrome

Large cell calcifying sertoli cell tumor (LCCSCT) is an exceptionally rare neoplasm originating from sperm cord cells. The tumors have relatively low malignant potential and unlikely proceed to metastasis formation. The lesions may occur in an isolated form or in ca. 40% of cases may be associated with genetic abnormalities, by and large Peutz–Jeghers syndrome and Carney complex. ...

Is hemojuvelin a possible new player in iron metabolism in hemodialysis patients?

Introduction Hemojuvelin (HJV) is highly expressed in the liver, skeletal muscles, and heart, seems to play a role in iron absorption and release from cells, and has anti-inflammatory properties. Moreover, HJV plays an essential role in the regulation of hepcidin expression, specifically in the iron-sensing pathway. Hepcidin has emerged as a key regulator of iron homeostasis. In ...

Membranoproliferative glomerulonephritis and a rare bleeding disorder: factor X deficiency

Factor X (FX) deficiency is a rare hereditary coagulation disorder. This is the first case report on the association of FX deficiency and membranoproliferative glomerulonephritis (MPGN) type I. The patient, a 17-year-old male, presented with edema, hypertension, and microscopic hematuria, followed by a mild upper respiratory tract infection. Laboratory tests revealed: serum ...

Renal cell carcinoma of native kidney in Chinese renal transplant recipients: a report of 12 cases and a review of the literature

Objectives To present and discuss the epidemiological and clinical aspects, as well as therapeutic options and outcome of de novo renal cell carcinoma (RCC) of the native kidneys in a series of Chinese renal transplant recipients. Patients and Methods A retrospective, cohort study examining all renal transplant recipients with the diagnosis of RCC of native kidney followed up in ...

Indinavir-induced nephrolithiasis three and one-half years after cessation of indinavir therapy

Nephrolithiasis is a known side effect of indinavir sulfate, a protease inhibitor used in the treatment of human immunodeficiency virus (HIV). The duration of its side effects, however, has not been well defined. We present a case where a patient presented with symptomatic indinavir-induced nephrolithiasis 3.5 years after discontinuing indinavir. We use this case to illustrate the ...

Update on potential medical treatments for encapsulating peritoneal sclerosis; human and experimental data

Encapsulating peritoneal sclerosis (EPS) is an infrequent but serious complication of peritoneal dialysis (PD). The pathogenesis is unknown but speculation is ongoing. The current management of EPS focuses on prevention and treatment of the inflammatory and fibrotic changes at the level of the peritoneal membrane with immunosuppressive and antifibrotic agents, respectively. This ...

New-onset diabetes after transplantation in tacrolimus-treated, living kidney transplantation: long-term impact and utility of the pre-transplant OGTT

Background To evaluate the role of the oral glucose tolerance test (OGTT) before transplantation and to examine the risk factors for new-onset diabetes after transplantation (NODAT) during long-term follow-up of renal transplant recipients receiving FK-based therapy. Methods The study evaluated 378 patients pre-transplantation using the OGTT and assigned them to one of three ...

Death with functioning kidney transplant: an obituarial analysis

Background Death with a functioning kidney graft (DWFG) is now a major cause of graft loss after renal transplantation, occurring in up to 40% of cases. Its occurrence provides insight into the medical care of subjects with a functioning kidney transplant. In this study, we used the time to DWFG as an endpoint, to test whether improved medical care has contributed to better kidney ...

Expression of P311, a transforming growth factor beta latency-associated protein-binding protein, in human kidneys with IgA nephropathy

Background In cultured NIH3T3 cells, P311 binds to the transforming growth factor-beta (TGF-β)-1 latency-associated protein (LAP) and induces the myofibroblast phenotype. In this study, we determined the levels of P311 and TGF-β1 proteins in tubulointerstitial tissue of patients with different severities of immunoglobulin-A nephropathy (IgAN), and analyzed the relationships between ...
