Abstract Background and Aims Hyperuricosuria is well documented to get involved in the pathogenesis of kidney stone disease, especially uric acid (UA) and calcium oxalate (CaOx) types. Nevertheless, hyperuricosuria-induced alterations in renal tubular cells and cascade mechanisms that subsequently trigger kidney stone formation remained largely unknown. This study aimed to examine changes in cellular proteome and function in renal tubular cells after treatment with high-dose UA. Method MDCK cells were incubated with 3.5 mM uric acid for 48-h. Cellular proteins were extracted and subjected to quantitative proteomics analysis using 2-D PAGE followed by nanoLC-ESI-ETD MS/MS. The proteome data were confirmed by Western blotting, whereas functional analyses were performed using various assays. Results Quantitative proteomics analysis revealed significant changes in levels of 22 proteins in the UA-treated cells that were related to ATPase activity, mitochondrial transport, cell adhesion and molecule binding, cell projection organization and maintenance of location network, metabolic process, response to unfold proteins, and vesicle-mediated transport. Western blotting confirmed changes in levels of cellular proteins identified by quantitative proteomics. Functional assays revealed an increase in intracellular ATP level and enhancement of tissue repair capability in the UA-treated cells. Interestingly, isolation/purification of apical membranes followed by Western blotting showed the increased levels of HSP70 and HSP90 (the known receptors for CaOx crystals) on apical membranes of the UA-treated cells. CaOx crystal-cell adhesion assay revealed significant increase in CaOx-binding capability of the UA-treated cells, whereas neutralization of the surface HSP70 and HSP90 using their specific monoclonal antibodies caused significant reduction in such binding capability (even below the basal level). Conclusion These findings highlighted changes in renal tubular cells in response to high-dose UA that might be related to the pathogenic mechanisms of kidney stone disease associated with hyperuricosuria.

AbstractBackground and purposeVisceral and somatic afferents activate the same neuronal structures in the central nervous system. Assessing somatosensory function and trophic changes in the referred pain area may therefore indirectly increase information on mechanisms involved in painful visceral diseases. The aim of this study was to evaluate the sensory and trophic changes in the flank corresponding to the referred pain area in patients with kidney stone disease.MethodsA total of 24 patients with unilateral pain-causing kidney stone disease were studied before and after endoscopic percutaneous kidney stone surgery. Trophic changes and sensitivity on the affected and on the contra-lateral side in the pain free period were investigated. For this purpose we used standardized experimental sensory testing including pressure stimulation and electrical (single and repeated) skin stimulation. Five repeated stimuli were used to investigate temporal summation (increased responses to repeated stimuli). To investigate trophic changes ultrasound as well as CT-scan was used, since the latter is considered more precise for exact tissue layer measurements.ResultsThe pain tolerance thresholds to pressure and pain thresholds to electrical stimulation were not significantly different on the two sides (all P>0.1). After surgery no significant alterations in sensitivity were detected, but there was a tendency to higher pain thresholds to electrical stimuli on the affected side (single stimuli P=0.06; repeated stimuli P=0.09). No trophic changes were observed (all P>0.3), and there were no relations between the pain thresholds or trophic findings and the number of colics (all P >0.08).ConclusionIn patients with unilateral pain-causing kidney stone disease the pain to experimental pressure and electrical stimuli were comparable on the affected and contra-lateral side. For the first time a CT-scan was used to evaluate tissue thickness in the referred pain area. No trophic changes were seen in the muscle or subcutaneous tissue at the affected side, and there were no correlations between the pain thresholds or trophic findings and the patients history of number of colics. After the operation no significant alterations in sensitivity were detected.ImplicationsThis study could not confirm previous studies showing referred hyperalgesia in the skin and trophic changes in the referred pain area to painful visceral disease. Differences in the pain intensity/duration between different diseases and hence the corresponding central neuronal changes may explain the negative findings in the present study.

Nutrition And Diet

The prevalence of kidney stone disease is increasing worldwide. The recurrence rate of urinary stones is estimated to be up to 50%. Nephrolithiasis is associated with increased risk of chronic and end stage kidney disease. Diet composition is considered to play a crucial role in urinary stone formation. There is strong evidence that an inadequate fluid intake is the major dietary risk factor for urolithiasis. While the benefit of high fluid intake has been confirmed, the effect of different beverages, such as tap water, mineral water, fruit juices, soft drinks, tea and coffee, are debated. Other nutritional factors, including dietary protein, carbohydrates, oxalate, calcium and sodium chloride can also modulate the urinary risk profile and contribute to the risk of kidney stone formation. The assessment of nutritional risk factors is an essential component in the specific dietary therapy of kidney stone patients. An appropriate dietary intervention can contribute to the effective prevention of recurrent stones and reduce the burden of invasive surgical procedures for the treatment of urinary stone disease. This narrative review has intended to provide a comprehensive and updated overview on the role of nutrition and diet in kidney stone disease.

Abstract Background and Aims Kidney stone disease is widely prevalent in the general population and has been associated with multiple comorbidities including hypertension, diabetes, chronic kidney disease and cardiovascular disease. We aimed to describe the possible link between stone composition and cardiovascular disease and its differential effect among women and men. Method Retrospective review of patients with known stone composition seen in a nephrolithiasis unit in the last five years. Anthropometric and clinical data were gathered from the hospital records. Stone composition was defined as such if ≥50% of the stone was made from a single component. Cardiovascular disease included coronary artery disease, stroke and peripheral vascular disease. Unadjusted and adjusted logistic regression analysis were applied to describe the potential relationship between stone composition and cardiovascular disease. Results 337 patients were included in the study sample. Median age was 57 (IQR 47-67), 61.1% males. 58.2% suffered from recurrent stone disease and 28.5% from family history of stone formation. 32.9% of patients had hypertension, 22,4% diabetes and 13,1% chronic kidney disease. The most common kidney stone component was calcium oxalate (38.6%) followed by calcium phosphate (21.3%), uric acid (14.2%), struvite (8%) and brushite (0.9%). Only uric acid as main stone component was associated with cardiovascular disease among men but not women in our sample in univariate analysis. That relationship was lost in adjusted logistic regression analysis. Conclusion Calcium oxalate and phosphate were the most common components of kidney stones. No relationship was found between stone composition and cardiovascular disease in the study sample.
