Genetic variation in APOL1 and MYH9 genes is associated with chronic kidney disease among Nigerians

Purpose A region of chromosome 22 which includes APOL1 and MYH9 genes was recently identified as a risk locus for non-diabetic forms of kidney disease, including idiopathic and HIV-associated focal segmental glomerular sclerosis and kidney disease clinically attributed to hypertension among African Americans. The purposes of the current study were, therefore, to examine the ...

Influence of megestrol acetate on nutrition, inflammation and quality of life in dialysis patients

Aim Malnutrition is a common clinical problem in dialysis patients. The objective of this study was to evaluate the efficacy and safety of megestrol acetate in malnourished dialysis patients. Thirty-two hypoalbuminemic dialysis patients took 160 mg of megestrol acetate daily for up to 6 months. Methods We measured height, dry weight, BMI, modified Subjective Global Assessment (SGA) ...

Bladder carcinoma in a 31-year-old female spina bifida patient with an auto-augmented bladder

We present the case of a 31-year-old spina bifida patient presenting with a poorly differentiated T3N1M0 bladder carcinoma with sarcomatoid differentiation in an auto-augmented bladder. She underwent a radical cystectomy and a bilateral lymph node dissection. However, only 10 months after the onset of her symptoms, she died after major lymphatic metastases had developed in the ...

Transferrin changes in haemodialysed patients

Transferrin (Tf) is a glycoprotein responsible for iron transport in the human body. Physiologically in reaction with Concanavalin A, Tf occurs in four distinct variants Tf1, Tf2, Tf3 (apo-Tf) and Tf4. It was reported recently that Tf is changing, particularly during acute phase response, taking place among others in end-stage renal disease. In this study, we wanted to find the ...

Renal function and adaptive changes in patients after radical or partial nephrectomy

Introduction Renal function after renal surgery depends on the volume of renal parenchyma loss and improves in the postoperative period. However, the knowledge on kidney function after radical (RN) and partial (PN) nephrectomy is still insufficient. The aim of this study is to analyze the global renal function and compensatory hyperfunction of the non-operated kidney in patients ...

Comparison of treatment results between holmium laser endourethrotomy and optical internal urethrotomy for urethral stricture

Purpose We comparatively evaluated urethral stricture (US) treatment outcomes, efficacy and complications, using either holmium laser endourethrotomy (HLU) or optical internal urethrotomy (OIU) since studies such as this are scarce in literature. Methods During 2003–2008, 50 men aged 17–78 years were operated on for primary or refractory US, 32 (64%) and 18 (36%) patients, ...

Lack of evidence for increased level of circulating urothelial cells in the peripheral blood after transurethral resection of bladder tumors

Purpose Aggressive intervention against the bladder wall during transurethral resection of bladder tumors (TURBT) causes damage and leakage from blood vessels to the bladder lumen. The aim of this study was to determine whether TURBT could increase the level of circulating urothelial cells. Methods Expression of tumor markers, discriminative for nucleated blood cells and ...

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 ...
