Abstract
It has been demonstrated in a number of studies that high levels of uric acid can cause crystal deposition in the tendons of the lower extremities, which in turn can impair the Achilles tendon. This study aimed to interpret whether hyperuricemia is relevant with Achilles tendon rupture. Patients diagnosed with Achilles tendon rupture at the same institution between 2013 and 2022 were included in the case group. Healthy subjects who had physical examinations during the same period were included in the control group. Propensity score matching was used to match in a 1:1 ratio. Demographic and clinical characteristics of patients in both groups were compared. Five hundred and fourteen patients were included in the study (ATR=257; Control group=257). The proportion of individuals with hyperuricemia varied significantly between the 2 groups (Achilles tendon rupture group=43.6%; control group=27.6%; p<0.001). The Achilles tendon rupture and hyperuricemia were linked by conditional logistic regression (p<0.001; OR=2.036; 95CI%=1.400-2.961). Compared with healthy subjects, patients with hyperuricemia have a higher risk of Achilles tendon rupture. Further studies are required to verify the effects of hyperuricemia and monosodium urate crystals on Achilles tendon structure.

[PMID: 38561771 PMCID: PMC10985911 DOI: 10.1186/s13018-024-04698-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Accepted: 03/24/2024] [Indexed: 04/04/2024] Open
Abstract
OBJECTIVE To study the correlation between achilles tendon rupture (ATR) and hyperuricemia, also verify the known risk factors for ATR. METHODS A retrospective review of 488 subjects was performed (182 with Achilles tendon rupture, 306 controls with ankle sprains). Demographic variables and risk factors for rupture were tabulated and compared. The baseline data and related indicators were compared, and the risk factors of ATR were analyzed by constructing a binary logistic regression model. RESULTS Univariate logistic analysis showed that BMI, smoking, and hyperuricemia were risk factors for the development of ATR (OR = 1.65, 95%CI 1.13-2.42, P = 0.01; OR = 1.47, 95%CI 1.00-2.24, P < 0.05; OR = 2.85, 95%CI 1.84-4.42, P < 0.01). Multifactorial analysis showed that BMI ≥ 25 kg/m2, smoking, and hyperuricemia were independent risk factors for the development of ATR (OR = 1.66, 95%CI 1.11-2.49, P = 0.01; OR = 2.15, 95%CI 1.28-3.60, P < 0.01; OR = 3.06, 95%CI 1.92-4.89, P < 0.01). Among the blood biochemical indicators, total cholesterol (TC) and uric acid (UA) were independent risk factors for the occurrence of ATR (OR = 1.54, 95% CI 1.12-2.12, P = 0.01; OR = 1.01, 95% CI 1.01-1.01, P < 0.01). CONCLUSION Our study confirmed that, as in previous results, higher BMI, smoking, and total cholesterol are risk factors for ATR, Hyperuricemia may contribute to the development of ATR, and adjunctive tests for TC and UA in the blood biochemistry may be helpful in predicting the risk of ATR.

van Dam L, Terink R, Mensink M, de Vos RJ, Zwerver J. The JUMPFOOD study: additional effect of hydrolyzed collagen and vitamin C to exercise treatment for patellar tendinopathy (jumper's knee) in athletes-study protocol for a double-blind randomized controlled trial. Trials 2023; 24:768. [PMID: 38017500 PMCID: PMC10685530 DOI: 10.1186/s13063-023-07783-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 11/06/2023] [Indexed: 11/30/2023] Open
Abstract
BACKGROUND Patellar tendinopathy (PT) is a common problem in jumping athletes. Management can be challenging and treatment outcome is not always successful. In combination with tendon loading exercises, hydrolyzed collagen/vitamin C supplementation appears to have a promising effect on the recovery of tendinopathy. The aim of this study is to evaluate whether the use of oral supplementation of hydrolyzed collagen and vitamin C in combination with progressive tendon loading exercises (PTLE) is superior to PTLE and placebo on VISA-P score (which rates pain, function, sports participation) after 24 weeks for athletes with PT. METHODS The JUMPFOOD study is a double-blinded, two-armed randomized controlled trial, in which the effectiveness of oral supplementation of hydrolyzed collagen/vitamin C combined with PTLE compared to PTLE with placebo on pain and recovery of function in athletes with PT will be investigated. Seventy-six athletes aged 16-40 years, with symptoms of PT for at least 12 weeks, who play sports at least once a week will be included. All participants will receive education, advice with regard to load management and a PTLE program according to the Dutch guidelines for anterior knee pain. In addition, the intervention group will receive daily 10 g hydrolyzed collagen and 40 mg vitamin C supplementation for 24 weeks whereas the control group receives 10 g maltodextrin placebo supplementation. Measurements will take place at baseline and at 12 and 24 weeks' follow-up. Primary outcome is the VISA-P score, which evaluates pain, function, and sports participation. For secondary outcome measures, data with regard to pain during functional tests, flexibility measurements, blood withdrawals, imaging characteristics of the tendon, and health questionnaires will be collected. During the follow-up period, participants will register sports participation, amount of training and tendon load, pain during sports, co-medication, and side-effects in a digital weekly diary. DISCUSSION The JUMPFOOD study is the first large RCT to study the effectiveness of hydrolyzed collagen/vitamin C supplementation in combination with the PTLE program in athletes with patellar tendinopathy. If supplementation of collagen/vitamin C appears to be effective, this treatment can be implemented in daily sports medicine practice to improve the treatment outcome of patients with PT. TRIAL REGISTRATION ClinicalTrials.gov NCT05407194. Registered on 7 June 2022.

Asymptomatic Hyperuricemia Is Associated with Achilles Tendon Rupture through Disrupting the Normal Functions of Tendon Stem/Progenitor Cells. Stem Cells Int 2022; 2022:6795573. [PMID: 36504525 PMCID: PMC9731760 DOI: 10.1155/2022/6795573] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 11/20/2022] [Accepted: 11/21/2022] [Indexed: 12/03/2022] Open
Abstract
Hyperuricemia is a metabolic disorder that is essential to the development of inflammatory gout, with increasing prevalence over recent years. Emerging clinical findings has evidenced remarkable tendon damage in individuals with longstanding asymptomatic hyperuricemia, yet the impact of hyperuricemia on tendon homeostasis and associated repercussions is largely unknown. Here, we investigated whether asymptomatic hyperuricemia was associated with spontaneous ruptures in the Achilles tendon and the pathological effect of hyperuricemia on the tendon stem/progenitor cells (TSPCs). Significantly higher serum uric acid (SUA) levels were found in 648 closed Achilles tendon rupture (ATR) patients comparing to those in 12559 healthy volunteers. In vitro study demonstrated that uric acid (UA) dose dependently reduced rat Achilles TSPC viability, decreased the expressions of tendon collagens, and deformed their structural organization while significantly increased the transcript levels of matrix degradative enzymes and proinflammatory factors. Consistently, marked disruptions in Achilles tendon tissue structural and functional integrity were found in a rat model of hyperuricemia, together with enhanced immune cell infiltration. Transcriptome analysis revealed a significant elevation in genes involved in metabolic stress and tissue degeneration in TSPCs challenged by hyperuricemia. Specifically, reduced activity of the AKT-mTOR pathway with enhanced autophagic signaling was confirmed. Our findings indicate that asymptomatic hyperuricemia may be a predisposition of ATR by impeding the normal functions of TSPCs. This information may provide theoretical and experimental basis for exploring the early prevention and care of ATR.

Abstract
Traditional Chinese Medicine (TCM) is a medical system with a distinctive theoretical framework and extensive experience in identification and treatment acquired by the Chinese people in long-term medical practice and life practice. It is a complete, integrated, and complex knowledge system in epistemology. This study is aimed at exploring the clinical effectiveness of TCM called the Guizhi Shaoyao Zhimu Decoction in the treatment of hyperuricemia. A total of 100 patients with hyperuricemia at the Medical College of the Second Clinical College, Shandong, China, from January 2019 to January 2022 are selected as the research subjects and divided into group A and group B according to the random table method, with 50 cases in each group. Group A is treated with oral allopurinol tablets, 100 mg, 2 times a day, and group B is treated with the modified Guizhi Shaoyao Zhimu Decoction based on group A. For observation, serum uric acid (SUA) levels, urinary uric acid (UUA) levels, levels of serum inflammatory response factors (IL-6, CRP, and TNF-α), vascular endothelial function indexes (serum malondialdehyde (MDA) content, nitric oxide (NO) content), an acute attack of gout, and the incidence of adverse reactions are measured. Results show that after 2 w and 4 w of treatment, the levels of blood uric acid in each group gradually decreased compared with those before treatment, and group B is lower than group A (P < 0.05). After treatment, the vascular endothelial function indexes and inflammatory factor levels in each group are significantly improved compared with those before treatment, and the indexes in group B are better than those in group A. There is no significant difference in the incidence of related adverse reactions and acute attack of gout (P > 0.05). This shows that the TCM Guizhi Shaoyao Zhimu Decoction has a significant curative effect in the treatment of patients with hyperuricemia, which is worthy of clinical reference application.

Abstract
Tendinopathy has been broadly characterized as alterations in cell proliferation, extracellular matrix turnover/synthesis, and inflammatory alterations. However, the underlying glucose metabolism pathways which contribute to these responses have not been well explored. The potential link between glucose metabolism and tendon pathology is interesting from a global standpoint since the development of spontaneous tendinopathy is associated with systemic metabolic disorders including diabetes mellitus. Therefore, the overarching goal of this study was to understand the potential pathogenic role of glucose metabolism-driven mechanisms in the development of tendinopathy. To test this, we have utilized an untargeted metabolomics approach to discover pathways which may be altered following tendinopathic injury and treadmill running in an established murine model of TGF-β1 induced tendinopathy. While specific tendon glucose alterations were not observed via metabolomics or 18 F-fluoroeoxyglucose (FDG) positron emission tomography/microcomputed tomography imaging (18 F-FDG PET/CT), metabolites including creatinine, D-chiro-inositol, and lipids were dysregulated following tendon injury. As novel pathways for manipulation, the creatine pathway, myo-inositol pathway, and lipid signaling may lead to the development of enhanced preventative strategies and therapeutic options for all patients who suffer from tendon-related injuries.

Abstract
Objective To investigate the effect of asymptomatic hyperuricemia on the effectiveness of arthroscopic rotator cuff repair. Methods The clinical data of 80 patients who underwent arthroscopic rotator cuff repair and met the selection criteria between March 2018 and December 2019 were retrospectively analyzed. According to the serum uric acid level, the patients were divided into hyperuric acid group (46 cases, the serum uric acid level was more than 417 μmol/L in males and was more than 357 μmol/L in females) and normal group (34 cases, serum uric acid level was lower than the above standard). There was no significant difference in gender, age, side, body mass index, blood glucose level, total cholesterol level, rotator cuff tear size, and preoperative shoulder motion, visual analogue scale (VAS) score, University of California-Los Angeles (UCLA) score, Constant score, American Shoulder and Elbow Surgeons (ASES) score, and other general data between the two groups ( P>0.05). The range of motion of abduction, forward flexion, and external rotation at 90° abduction were recorded and compared between the two groups before operation and at last follow-up; the improvement of shoulder pain was evaluated by VAS score; the improvement of shoulder function was evaluated by UCLA score, Constant score, and ASES score; and the shoulder joint MRI grade was evaluated according to Sugaya evaluation criteria. Results All patients were followed up 9-16 months, with an average of 11.9 months; there was no significant difference in the follow-up time between the two groups ( t=0.968, P=0.336). There were 2 cases of retear in the hyperuric acid group (including 1 case of severe tear) and 1 case of light retear in the normal group. The remaining patients in the two groups had no early-related complications. At last follow-up, the range of motion of the shoulder joints (abduction, forward flexion, external rotation at 90° abduction), VAS score, UCLA score, Constant score, and ASES score of the two groups were significantly improved when compared with preoperative ones ( P<0.05); the above indicators in the normal group were significantly better than those in the hyperuric acid group ( P<0.05). The MRI grade of the shoulder joint in the normal group was significantly better than that in the hyperuric acid group ( Z=-2.000, P=0.045). Conclusion Compared with patients with normal serum uric acid level, asymptomatic hyperuricemia can lead to worse recovery after arthroscopic rotator cuff repair in patients with rotator cuff tears.

Abstract
PURPOSE The purpose of the current study was to compare demographic differences and ultrasonographic features in primary trigger finger and trigger finger in association with hyperuricemia. METHODS Between October 2008 and February 2010, a prospective review of consecutive cases of 54 patients with trigger finger and hyperuricemia, 76 patients with a trigger finger without hyperuricemia, and 80 control cases were enrolled. The clinical results were analyzed by descriptive epidemiology, an ultrasonographic measurement of the thickness of A1 pulley, cross-sectional area of the flexor tendon and synovium. RESULTS The middle finger was primarily affected, followed by the index and ring fingers in both trigger finger groups. The thickness of A1 pulley, cross-sectional area of the flexor tendon, and flexor tendon with synovium in trigger finger without hyperuricemia group were significantly larger than that in trigger finger with hyperuricemia and control groups. There was no significant difference between trigger finger with hyperuricemia and control groups. Double-contour sign and tophus were only observed in trigger finger with hyperuricemia group. CONCLUSIONS Thickness of A1 pulley, cross-sectional area of the flexor tendon, and flexor tendon with synovium were significantly larger in trigger finger without hyperuricemia group. These findings were not evident in trigger finger with hyperuricemia group.

Abstract
Tendinopathy in the presence of gouty arthropathy is relatively common, yet the clinical suspicion for gout involvement in acute tendon pain remains low. A 49-year-old man presented with an acute, tender, erythematous mass to the right posterior heel. A computed tomographic scan was obtained, which revealed a septated fluid collection superficial to the Achilles tendon. The patient was taken to the operating room for an incision and drainage with debridement, and the abscess was found to be filled with caseous material. The diagnosis of gout was confirmed with pathology. The calcaneus was submitted to biopsy, and the results were negative for osteomyelitis. The patient was returned to the operating room for repair of the Achilles tendon with flexor hallucis longus tendon transfer. Postoperatively, the patient was nonweightbearing for 6 weeks. Oral colchicine was used perioperatively, and a steroid taper was administered. The patient was started on allopurinol and colchicine for chronic treatment. At 14 months, the patient was walking without pain or recurrence of the mass. Although the relationship between hyperuricemia and tendinopathy is not completely understood, it is apparent that tendon involvement may be a sequela in patients with gout. When a patient presents with acute tendon pain, gout should be considered in the differential diagnosis.

Abstract
The current pilot study investigates whether oral supplementation of specific collagen peptides improves symptoms and tendon vascularisation in patients with chronic mid-portion Achilles tendinopathy in combination with structured exercise. Participants were given a placebo or specific collagen peptides (TENDOFORTE®) in combination with a bi-daily calf-strengthening program for 6 months. Group AB received specific collagen peptides for the first 3 months before crossing over to placebo. Group BA received placebo first before crossing over to specific collagen peptides. At baseline (T1), 3 (T2) and 6 (T3) months, Victorian Institute of Sports Assessment–Achilles (VISA-A) questionnaires and microvascularity measurements through contrast-enhanced ultrasound were obtained in 20 patients. Linear mixed modeling statistics showed that after 3 months, VISA-A increased significantly for group AB with 12.6 (9.7; 15.5), while in group BA VISA-A increased only by 5.3 (2.3; 8.3) points. After crossing over group AB and BA showed subsequently a significant increase in VISA-A of, respectively, 5.9 (2.8; 9.0) and 17.7 (14.6; 20.7). No adverse advents were reported. Microvascularity decreased in both groups to a similar extent and was moderately associated with VISA-A (Rc2:0.68). We conclude that oral supplementation of specific collagen peptides may accelerate the clinical benefits of a well-structured calf-strengthening and return-to-running program in Achilles tendinopathy patients.
