By stepwise extraction of kidney stones, first with 10% acetic acid then 0.1 M EDTA, three pools of protein material have been obtained. The soluble material from the acid extract showed well defined bands when analyzed by sodium dodecyl sulfate (SDS) gel electrophoresis, and amino acid sequence
The incidence of nephrolithiasis (kidney stones) is rising worldwide, especially in women and with increasing age. Kidney stones are associated with chronic kidney disease. Preventing recurrence is largely specific to the type of stone (e.g., calcium oxalate, calcium phosphate, cystine, struvite
OBJECTIVE
The effects of two antiretroviral triple combinations including the protease inhibitor indinavir on the surrogate markers, viral load and CD4 cells were evaluated.
METHODS
Fifteen patients with high viral load or disease progression under their prior antiretroviral therapy were switched to
The external appearance of urinary calcium oxalate (CaOx) crystals suggests that they are solid, homogeneous structures, despite their known association with proteins. Our aim was to determine whether proteins comprising the organic matrix of CaOx crystals are superficial or intracrystalline in
To investigate the safety and efficacy of extracorporeal shock wave lithotripsy (ESWL) combined with percutaneous nephrolithotomy (PCNL) for treatment of complex renal calculus.
Seventy-eight patients diagnosed with complex renal calculus and who accepted treatment in our hospital were consecutively
Hepsin, a transmembrane serine protease abundant in renal endothelial cells, is a promising therapeutic target against several cancers, particularly prostate cancer. It is involved in the release and polymerization of uromodulin in the urine, which plays a role in kidney stone formation. In this
OBJECTIVE
To determine the effectiveness and safety of adding delavirdine mesylate to a treatment regimen that included indinavir and nucleoside analog reverse transcriptase inhibitors in patients in whom combination therapy had failed.
METHODS
Observational study.
METHODS

Calcium oxalate kidney stones contain low amounts of proteins, some of which have been implicated in progression or prevention of kidney stone formation. To gain insights into the pathophysiology of urolithiasis, we have characterized protein components of calcium oxalate kidney stones by proteomic
Osteopontin (OPN) is a multifunctional glycosylated phosphoprotein found in body fluids, including urine, and has been implicated in urinary stone formation. We tested the hypothesis that OPN levels in urine of patients with kidney stones differed from normal individuals. To quantify OPN levels in
Drug-induced calculi represent 1-2% of all renal calculi. The drugs reported to produce calculi may be divided into two groups. The first one includes poorly soluble drugs with high urine excretion that favour crystallisation in the urine. Among them, drugs used for the treatment of patients with
A number of drugs prescribed for the treatment of various diseases can induce urological symptoms as side effects. Antihypertensive drugs (particularly alpha blockers) can result in stress incontinence, whereas selective serotonin reuptake inhibitors (SSRI) can cause urge incontinence and estrogen
A 64-year-old man with HIV on antiretroviral therapy (including atazanavir, a protease inhibitor) presented with left flank pain, nausea and vomiting. A kidney stone was suspected, and a CT scan demonstrated left hydronephrosis but failed to demonstrate nephrolithiasis or extrinsic compression. The
Nephrolithiasis is a well-known side effect of many HIV protease inhibitors. However, there have not been reports of stones associated with ritonavir use. Here, we report the case of a 33-year-old woman with HIV on antiretroviral therapy who presented with sharp left flank pain and passed a stone
Pycnodysostosis is a rare autosomal recessive skeletal dysplasia characterized by short stature, osteosclerosis, acro-osteolysis, frequent fractures, and skull deformities. Mutation in the gene encoding cathepsin K (CTSK), which is a lysosomal cysteine protease, has been found to be responsible for
OBJECTIVE
Atazanavir has been associated with kidney stones and renal failure. We measured urine and plasma concentrations of recent protease inhibitors (PIs) and searched for PI crystals in the urine of asymptomatic patients.
METHODS
A cross-sectional analysis of HIV-infected patients taking
