Low-Energy Extracorporeal Shock Wave Therapy Ameliorates Kidney Function in Diabetic Nephropathy.

ABSTRACT: Background:Diabetic nephropathy is the most common cause of end-stage renal disease. Traditional therapy for diabetic nephropathy has focused on supportive treatment, and there is no significant effective therapy. We investigated the effect of low-energy extracorporeal shock wave therapy on a diabetic nephropathy rat model. Methods:Streptozotocin-induced diabetic nephropathy rats were treated with six sessions of low-energy extracorporeal shock wave therapy (weekly for six consecutive weeks) or left untreated. We assessed urinary creatinine and albumin, glomerular volume, renal fibrosis, podocyte number, renal inflammation, oxidative stress, and tissue repair markers (SDF-1 and VEGF) six weeks after the completion of treatment. Results:The six-week low-energy extracorporeal shock wave therapy regimen decreased urinary albumin excretion as well as reduced glomerular hypertrophy and renal fibrosis in the rat model of diabetic nephropathy. Moreover, low-energy extracorporeal shock wave therapy increased podocyte number in diabetic nephropathy rats. This was likely primarily attributed to the fact that low-energy extracorporeal shock wave therapy reduced renal inflammation and oxidative stress as well as increased tissue repair potency and cell proliferation. Conclusions:Low-energy extracorporeal shock wave therapy preserved kidney function in diabetic nephropathy. Low-energy extracorporeal shock wave therapy may serve as a novel noninvasive and effective treatment of diabetic nephropathy.

Project description:BACKGROUND: There are several treatment options for calcifying tendinitis of the shoulder. The next step treatment after conservative treatment fails is still a matter of dispute. Extracorporeal shock wave therapy (ESWT) has been shown to be a good alternative to surgery, but the best treatment intensity remains unknown. High-energy ESWT is much more painful, more expensive, and usually is done in an inpatient setting, whereas low-energy ESWT can be performed in an outpatient setting by a physical therapist. QUESTIONS/PURPOSES: A systematic review and meta-analysis of randomized trials was performed to answer two clear research questions: (1) Is there a greater increase in the Constant-Murley score in patients treated with high-energy ESWT compared with those treated with low-energy ESWT by 3 months and by 6 months? (2) Is there a greater chance of complete resorption of the calcifications in patients treated with high-energy ESWT compared with those treated with low-energy ESWT by 3 months and by 6 months? METHODS: Five relevant electronic online databases, Medline (through PubMed), EMBASE (through OVID), Cinahl (through EBSCO), Web of Science, and the Cochrane Central Register of Controlled Trials, were systematically searched. We also crosschecked the reference lists of articles and reviews for possible relevant studies. Eligible for inclusion were all randomized controlled trials (RCTs) that compared high-energy ESWT (> 0.28 mJ/mm(2)) with low-energy ESWT (< 0.08 mJ/mm(2)). One author examined titles and abstracts of each identified study to assess study eligibility. Two reviewers independently extracted data and assessed the risk of bias and study quality. The primary outcome measure, the Constant-Murley score, was assessed by comparing mean functional outcome scores between the groups. Secondary outcomes were assessed using odds ratios, when appropriate data were pooled. Based on this process, five RCTs (359 participants) were included. RESULTS: All five RCTs showed greater improvement in functional outcome (Constant-Murley score) in patients treated with high-energy ESWT compared with patients treated with low-energy ESWT at 3 and 6 months. The 3-month mean difference was 9.88 (95% CI, 9.04-10.72, p < 0.001; 6-month data could not be pooled). Furthermore, high-energy ESWT more often resulted in complete resorption of the deposits at 3 months. The corresponding odds ratio was 3.40 (95% CI, 1.35-8.58) and p = 0.009 (6-month data could not be pooled). CONCLUSION: When shock wave therapy is chosen, high-energy shock wave therapy is more likely to result in improved Constant-Murley score and resorption of the deposits compared with low-energy therapy. LEVEL OF EVIDENCE: Level I, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.

Project description:BackgroundsConsidering the natural course of cavernous nerve recovery after robot-assisted laparoscopic prostatectomy (RALP), early intervention of low intensity extracorporeal shock wave therapy (LIESWT) would be more effective for enhancing overall recovery of sexual function (SF). Our objective of this study is to analyze longitudinally the alterations of SF in patients after RALP, with a focus on the effect of early and delayed intervention with LIESWT.MethodsA total of 5 and 11 patients underwent early and delayed intervention with LIESWT, respectively. SF was assessed with the Expanded Prostate Cancer Index Composite (EPIC). The same surgeon performed RALP on 178 patients, and these patients were assigned to the non-LIESWT group to establish a control group. The SF score of EPIC was investigated longitudinally before RALP and 3, 6, 9, and 12 months after RALP.ResultsOur results show that penile rehabilitation with LIESWT immediately before urethral catheter removal improved SF scores. In the baseline, the SF score was significantly higher in the early LIESWT group (P=0.0001). The SF score was significantly lower at postoperative 6 months (early 19.2, delayed 17.9, and non-LIESWT 8.1; P=0.0171), 9 months (20.9, 25.8, and 10.2; P=0.0188), and 12 months (28.0, 21.3, and 9.5; P=0.0051) in the non-LIESWT group. We regret that there was no significant difference in the recovery of SF between the early and delayed protocol with LIESWT at all points. In keeping with our results, LIESWT demonstrated the potential to be efficacious in treatment options for severe post-radical prostatectomy (RP) erectile dysfunction (ED) as it may indirectly support its promotion of nerve regeneration in severe ED due to RP.ConclusionsThis is the first study in which LIESWT has been shown to deliver a clinical benefit on its early or delayed intervention to patients after RALP to penile rehabilitation in terms of restoring SF. Our preliminary results suggest that LIESWT could be used as a treatment option in penile rehabilitation.

Project description:ObjectiveTo evaluate the effect of low-protein diet on kidney function in patients with diabetic nephropathy.DesignA systematic review and a meta-analysis of randomised controlled trials.Data sourcesMEDLINE, EMBASE, Cochrane Library, ClinicalTrials.gov, International Standard Randomised Controlled Trial Number (ISRCTN) Register and University Hospital Medical Information Network-Clinical Trials Registry (UMIN-CTR) from inception to 10 December 2012. Internet searches were also carried out with general search engines (Google and Google Scholar).Study selectionRandomised controlled trials that compared low-protein diet versus control diet and assessed the effects on kidney function, proteinuria, glycaemic control or nutritional status.Primary and secondary outcome measures and data synthesisThe primary outcome was a change in the glomerular filtration rate (GFR). The secondary outcomes were changes in proteinuria, post-treatment value of glycated haemoglobin A1C (HbA1c) and post-treatment value of serum albumin. The results were summarised as the mean difference for continuous outcomes and pooled by the random effects model. Subgroup analyses and sensitivity analyses were conducted regarding patient characteristics, intervention period, methodological quality and assessment of diet compliance. The assessment of diet compliance was performed based on the actual protein intake ratio (APIR) of the low-protein diet group to the control group.ResultsWe identified 13 randomised controlled trials enrolling 779 patients. A low-protein diet was associated with a significant improvement in GFR (5.82 ml/min/1.73 m(2), 95% CI 2.30 to 9.33, I(2)=92%; n=624). This effect was consistent across the subgroups of type of diabetes, stages of nephropathy and intervention period. However, GFR was improved only when diet compliance was fair (8.92, 95% CI 2.75 to 15.09, I(2)=92% for APIR <0.9 and 0.03, 95% CI -1.49 to 1.56, I(2)=90% for APIR ?0.9). Proteinuria and serum albumin were not differed between the groups. HbA1c was slightly but significantly decreased in the low-protein diet group (-0.26%, 95% CI -0.35 to -0.18, I(2)=0%; n=536).ConclusionsLow-protein diet was significantly associated with improvement of diabetic nephropathy. The adverse effects of low-protein diet were not apparent such as worsening of glycaemic control and malnutrition.
