Clinical Trial Summary

Humeral epicondylopathies are common disorders which can significantly impair upper limb function. In case of failure of rehabilitation protocol there is no evidence based second line therapy. It is common practice to perform one of the injection procedures. The biological mechanisms of these procedures are unclear, and may even be contrary. These include, but are not limited to, injections of corticosteroids, autologous platelet rich plasma (PRP) and hyaluronic acid (HA). Despite the frequent use there is much controversy about their clinical effectiveness and more evidence based data are required. The aim of the study is to compare three different injection therapies for lateral epicondylopathy. In addition, correlation between selected bioactive compounds in PRP and its clinical effectiveness will be evaluated. The study is planned as a single-center, prospective, randomized, double-blinded, controlled trial on 120 patients aged 30-60 who suffer for lateral epicondylitis. After meeting the inclusion and exclusion criteria patients will receive an injection of leukocyte-rich autologous PRP (N1), corticosteroid (N2), HA (N3) in the area of the common extensors tendon attachment, respectively. Patients from control group (N4) will get an injection of saline in the same area. All groups will be instructed how to perform everyday stretching and strengthening exercises. Evaluation of clinical effectiveness of the treatment will be based on objective measurements such as range of motion, limb girth, grip strength, X-ray and ultrasound examination and subjective measurements such as pain (VAS), functional (PRTEE, DASH, SEV, MEPS) and quality of life questionnaires (SF-36) before and during follow-up period (1, 4, 12, 24, 52 weeks). PRP samples will undergo laboratory analysis of levels of bioactive compounds including platelets, white blood cells, erythrocytes and selected growth factors and inflammatory cytokines. After data collection, the clinical effectiveness of three different injection therapies will be evaluated and statistically analyzed. Subjective and objective outcomes, safety, costs-effectiveness of three different injection therapies compared to placebo and between each other will be assessed. In addition, correlation between levels of bioactive compounds in PRP and its efficacy will be checked.


Description:

The study will be a single-center, prospective, randomized, double-blinded, controlled trial with placebo. It is planned to enroll 120 patients with lateral epicondylopathy and divide them to four equal groups receiving an autologous platelet rich plasma (PRP) (N1=30), corticosteroid (N2=30) or hyaluronic acid (N3=30) injection in the area of lateral epicondyle, or to control group (N4=30) receiving an injection of saline in the same area. After meeting the inclusion and exclusion criteria and before therapeutic intervention patients will undergo clinical and radiological examination and laboratory analysis of blood samples - complete blood count, C reactive protein (CRP), selected cytokines. Elbow anterior-posterior and lateral view X-ray and ultrasound examination will be performed to find signs of enthesopathy, asses calcifications and to exclude other pathologies. To measure the clinical effectiveness of the treatment examination including range of motion, limb girth measurements, grip and muscle strength measured by dedicated device (digital dynamometer) and regional pain severity measured by professional digital algometer will be performed. Patients will be asked to fulfil pain, functional and quality of live questionnaires, including Visual Analog Scale for pain intensity evaluation (VAS), Patient-rated Tennis Elbow Evaluation (PRTEE), Disabilities of the Arm, Shoulder, and Hand (DASH), The Mayo Elbow Performance Score (MEPS), The Oxford Elbow Score, The Subjective Elbow Value (SEV) and The Quality of life questionnaire SF-36. Patients from the experimental group will receive an injection of autologous platelet-rich plasma (PRP) without activator (2ml) in the area of attachment of the common extensor tendon under supervision of ultrasound (N1=30), corticosteroid - 2ml of 7mg Betamethasone (N2=30) or 2ml of 40mg hyaluronic acid with mannitol (N3=30). Patients from control group will get an injection of saline (2ml 0,9% NaCl) in the same area (N=30). The injection will be carried out with aseptic precautions, under regional anesthesia with Lignocaine 1%. Saline injection as placebo intervention for control group was chosen because of a similar impression for the patient comparing to other injections. Also there are some previously reported positive outcomes of that kind of intervention alone. The procedure will be performed in accordance with the principle of double-blinding. Every patient will get identification number which will be randomly assigned to one from all groups, in equal proportion. Both, patient and investigator will not know what kind of substance was used for the treatment. Only person giving the injection will have access to patients identification numbers list and will know the exact type of treatment. Part of the PRP sample (1ml) will undergo laboratory analysis of levels of bioactive compounds. Assessment of levels and concentrations of platelets, white blood cells and erythrocytes will be performed. The investigators will evaluate the content of selected cytokines in PRP using flow cytometry for growth hormones: Platelet Derived Growth Factor-AA (PDGF-AA), Platelet Derived Growth Factor-BB (PDGF-BB), Vascular Endothelial Growth Factor (VEGF), Epidermal Growth Factor (EGF), Hepatocyte Growth Factor (HGF), Fibroblast Growth Factor basic (FGF), Transforming Growth Factor Beta1 free active (TGFβ1) and inflammatory cytokines: Interleukin-1β (IL-1β), Interferon-α2 (IFN-α2), Interferon-γ (IFN-γ), Tumor Necrosis Factor -α (TNF-α), Monocyte Chemotactic Protein -1 (MCP-1), Interleukin-6 (IL-6), Interleukin-8 (IL-8), Interleukin-10 (IL-10), Interleukin-12p70 (IL-12p70), Interleukin-17A (IL-17A), Interleukin-18 (IL-18), Interleukin-23 (IL-23), Interleukin-33 (IL-33). Patients will be reassessed 1, 4, 12, 24 and 52 weeks after intervention. All patients will undergo ultrasound examination before treatment and during follow-up period. Every group will be instructed how to perform everyday stretching and strengthening exercises during the whole period of the study. All information about any complications will be collected and evaluated. After data unblinding, statistical analysis will be performed. Subjective and objective outcomes, safety, costs-effectiveness of three different injection therapies compared to placebo and between each other will be assessed. There are no original studies comparing clinical effectiveness between corticosteroid, hyaluronic acid, autologous platelet rich plasma and placebo in patients with elbow tendinopathy. There are only few good quality studies on the clinical effectiveness of lateral epicondylopathy treatment with different injection therapies. Most of them compare only one injection method to active comparator or placebo. Usually follow-up period is less than 3 months. Frequent follow-up visits will help to reliably evaluate rate of recurrence and to evaluate correlation between subjective and objective (e.g. USG) findings. It is believed that results of this study will show significant positive clinical effect of different injection treatments of patients with lateral humeral epicondylopathy. The investigators would like to find which one from injection treatments among corticosteroids, autologous platelet rich plasma and hyaluronic acid will provide best outcomes, safety profile, short and long-term efficacy, cost-effectiveness and the fastest return to work. The results of the study will increase the knowledge about the treatment of lateral epicondylopathy, helping to create a reliable algorithm for supporting the decision-making process in everyday clinical practice.
