Introduction & Objectives: Radiation-induced haemorrhagic cystitis (RHC) is a frightening complication occurring after pelvic radiotherapy (PRT) which may significantly affect patients' quality of life. Bladder instillation with glycosaminoglycan replacement therapy (GRT) including hyaluronic acid +/- chondroitin sulphate has been proposed as an emerging alternative to prevent relapses of haematuria. Strong points in favour of using GRT for RHC are the ease of administration, cost, almost absence of side effects and possibility of administration to outpatients. We investigated the effectiveness of GRT in a cohort, single-centre, of patients with past-medical history of PRT attending the outpatient clinic and/or the accident & emergency department (A&E) for RHC., Materials & Methods: Patients with diagnosis of RHC, either with toxicity grade of 2 or 3, were deemed candidate for GRT as long as no active bleeding was occurring; in the case of non-self-limiting haematuria and/or anaemia for active bleeding, admission in the urology department was prompted for bleeding control prior to GRT instillation. An induction course of 6 weekly instillations was scheduled; if tolerated, patients were given a maintenance course with at least 6 monthly instillations. The primary end-point consisted in assessing the rate of haematuria remission (either partial or complete) defined as no need to readmission in the A&E and/or in the hospital. Secondary end-points included factors related to GRT failure. Univariate and multivariate analysis were undertaken to identify clinical independent variables associated to the events., Results: Fifty-one patients with at least 1-year follow-up from the first GRT were included in the analysis. 88.2, 9.8 and 2% of patients had undergone PRT because affected by prostate, uterus and colorectal cancer, respectively. Median time-to-RHC was 31 months (IQR 21-90). Access to A&E and hospital admission were needed in 47 (92.1%) and 35 (68.6%) of the patients, respectively. Twenty-two (n = 22/35, 62.9%) patients required transurethral fulguration of the bladder, while the remainders could be managed with bladder wash-out. Median number of GRT instillations was 6 (IQR 3-7). Twenty-three (45.1%) patients needed to be readmitted to hospital a second time, receiving bladder wash-out (n = 7/23, 30.4%), transurethral fulguration of the bladder (n = 10/23, 43.5%) and/or cystectomy (n = 6/23, 26.1%). Ten (19.6%) patients received a second induction course of GRT. At the last follow-up, 36 (70.6%) patients did not required further hospital admission. Type of PRT and number of hospital admissions pre-GRT were the only variables statistically associated to the events at both univariate (P = 0.032 and P = 0.045) and multivariate analysis (P = 0.048 and P = 0.049)., Conclusions: GRT should be prompted as soon as possible after diagnosis of the haematuria and settling of active bleeding. Patients who had undergone adjuvant PRT after radical prostatectomy are those at higher risk of GRT failure., Competing Interests: Conflict of interests The authors certify that there is no conflict of interest with any financial organization regarding the material discussed in the manuscript., (Copyright © 2022 Elsevier Inc.

Sulodexide is a glycosaminoglycan extracted from porcine intestinal mucosa. The purpose of this review is to discuss sulodexide's complex pharmacological profile and its clinical applications for venous disease. Sulodexide has wide-ranging biological effects on the vascular system, including antithrombotic, profibrinolytic, anti-inflammatory, endothelial protective and vasoregulatory effects. Sulodexide has emerged as a potential therapeutic option for the management of chronic venous insufficiency, including venous ulceration, and the prevention of recurrent venous thromboembolism, with a low rate of major bleeding complications. Sulodexide's pleiotropic vascular effects may facilitate the management of common venous disorders., (© 2018 International Society on Thrombosis and Haemostasis.)

Objectives: The aim of this study was to evaluate the acute and chronic effects of mesoglycan on the endothelial function and arterial elastic properties in patients with metabolic syndrome (MetS)., Background: MetS is defined by a clustering of vascular risk factors that demand both pharmacologic and non-pharmacologic interventions, including body weight reductions and physical activity. The correction of endothelial dysfunction and arterial wall distensibility associated with MetS have lately received increasing interest., Methods: Thirty consecutive ambulatory patients affected by MetS were 2:1 randomized in a double-blind fashion to receive mesoglycan or placebo, respectively. In the first phase of the study, we evaluated the acute effects of a single i.m. administration of mesoglycan (60 mg) or placebo on vascular reactivity, as assessed by brachial flow-mediated dilation (FMD). Then, patients were chronically treated with mesoglycan per os (50 mg twice a day) or placebo for 90 days. At the end of this period, vascular reactivity and the arterial wall elastic properties were evaluated., Results: In the mesoglycan group, FMD increased above baseline after acute administration, with a maximum increment of 52% after 2 h. FMD was also significantly greater than baseline after 90 days of chronic treatment. In the placebo group, FMD was unaffected by both acute and chronic mesoglycan administration. Moreover, after 90 days of mesoglycan treatment, a marked improvement in arterial distensibility and compliance was detected and arterial stiffness reduced significantly., Conclusions: This small, preliminary study shows that mesoglycan exerts relevant effects on vascular physiology, both in an acute setting as well as after prolonged, three-month treatment, in patients affected by metabolic syndrome., (Copyright © 2015 Elsevier Ireland Ltd.

Background: Few evidence-based treatment guidelines for tendinopathy exist. We undertook a systematic review of randomised trials to establish clinical efficacy and risk of adverse events for treatment by injection., Methods: We searched eight databases without language, publication, or date restrictions. We included randomised trials assessing efficacy of one or more peritendinous injections with placebo or non-surgical interventions for tendinopathy, scoring more than 50% on the modified physiotherapy evidence database scale. We undertook meta-analyses with a random-effects model, and estimated relative risk and standardised mean differences (SMDs). The primary outcome of clinical efficacy was protocol-defined pain score in the short term (4 weeks, range 0-12), intermediate term (26 weeks, 13-26), or long term (52 weeks, ≥52). Adverse events were also reported., Findings: 3824 trials were identified and 41 met inclusion criteria, providing data for 2672 participants. We showed consistent findings between many high-quality randomised controlled trials that corticosteroid injections reduced pain in the short term compared with other interventions, but this effect was reversed at intermediate and long terms. For example, in pooled analysis of treatment for lateral epicondylalgia, corticosteroid injection had a large effect (defined as SMD>0·8) on reduction of pain compared with no intervention in the short term (SMD 1·44, 95% CI 1·17-1·71, p<0·0001), but no intervention was favoured at intermediate term (-0·40, -0·67 to -0·14, p<0·003) and long term (-0·31, -0·61 to -0·01, p=0·05). Short-term efficacy of corticosteroid injections for rotator-cuff tendinopathy is not clear. Of 991 participants who received corticosteroid injections in studies that reported adverse events, only one (0·1%) had a serious adverse event (tendon rupture). By comparison with placebo, reductions in pain were reported after injections of sodium hyaluronate (short [3·91, 3·54-4·28, p<0·0001], intermediate [2·89, 2·58-3·20, p<0·0001], and long [3·91, 3·55-4·28, p<0·0001] terms), botulinum toxin (short term [1·23, 0·67-1·78, p<0·0001]), and prolotherapy (intermediate term [2·62, 1·36-3·88, p<0·0001]) for treatment of lateral epicondylalgia. Lauromacrogol (polidocanol), aprotinin, and platelet-rich plasma were not more efficacious than was placebo for Achilles tendinopathy, while prolotherapy was not more effective than was eccentric exercise., Interpretation: Despite the effectiveness of corticosteroid injections in the short term, non-corticosteroid injections might be of benefit for long-term treatment of lateral epicondylalgia. However, response to injection should not be generalised because of variation in effect between sites of tendinopathy., Funding: None., (Copyright © 2010 Elsevier Ltd. All rights reserved.)

Objectives: to assess the effect of treatment with mesoglycan, a sulphated polysaccharide compound, on the healing of venous ulcers. Design randomised, placebo-controlled, double-blind, multicentre trial., Methods: non-diabetic outpatients with chronic venous insufficiency confirmed by duplex ultrasound, normal ankle/arm pressure index and presence of a leg ulcer were eligible. Patients were randomised to mesoglycan, 30 mg/day intramuscularly for 3 weeks followed by 100 mg/day orally, or matching placebo, as an adjunct to compression therapy and topical wound care. Treatment and observation were continued until complete ulcer healing or for 24+/-1 weeks. Time to ulcer healing and healing rates were estimated with the Kaplan-Meier method., Results: One hundred and eighty-three patients were randomised and included in the analysis (92 mesoglycan, 91 placebo). Median ulcer area upon inclusion was 3.6 cm(2)in the mesoglycan group and 3.9 cm(2)in the placebo group. The estimated time to heal 75% of the patients was 90 days on mesoglycan versus 136 days on placebo, while the cumulative rate of healing by the end of observation was 97% versus 82%, respectively. The difference in favour of mesoglycan was statistically significant (p < 0.05, centre-stratified Cox's model). The relative risk of ulcer healing with mesoglycan was 1.48. The rate of adverse events was 7/92 on mesoglycan and 6/91 on placebo., Conclusions: treatment with mesoglycan in addition to established venous ulcer therapy resulted in a significantly faster and more frequent ulcer healing, and did not raise any safety concerns., (Copyright 2001 Harcourt Publishers Limited.)
