Background Lateral epicondylitis is one of the commonly noticed disorders of the arm described by agony focused over lateral epicondyle which is the site of wrist extensors origin. The purpose of this work was to compare the efficiency of extracorporeal shock wave therapy and local corticoid injection in management of lateral epicondylitis both clinically and ultrasonographically as well as to assess the role of ultrasound in diagnosis and follow-up of lateral epicondylitis. This study was performed on 30 athletes diagnosed as lateral epicondylitis. Results Both corticosteroid injection and shock wave treatment showed a highly significant effectiveness on pain by visual analog scale (VAS). A highly significant difference between before treatment and after 2 as well as 4 weeks of treatment regarding the functional disability parameters as patient-rated tennis elbow evaluation (PRTEE) and quick disabilities of the arm, shoulder, and hand (DASH) was found. Likewise, a statistically significant improvement in favor of shock wave therapy group after 2 weeks was found, inversely insignificant difference after 8 and 12 weeks regarding to VAS occurred. Both PRTEE and Quick DASH test showed a statistically significant difference among groups through all follow-up period. There was a statistically insignificant difference among the studied groups according to ultrasound (US) changes in the form of focal areas of hypo-echogenicity through follow-up periods. A significant improvement in favor of ESWT group is detected among the studied groups regarding tendon thickening in ultrasonography before treatment and after 2 and 4 weeks. However, the difference was insignificant after 8 and 12 weeks. Conclusions Both corticosteroid local injection and shock wave therapy are helpful and effective for lateral epicondylitis treatment. However, a shock wave therapy revealed better improvement on long-term clinical and ultrasonogrphic follow-up than corticosteroid injection. Musculoskeletal ultrasound represents a helpful diagnostic and follow-up tool for lateral epicondylitis.
Introduction Systemic sclerosis (SSc) is an autoimmune disorder that causes vasculopathy and scarring, most commonly in the lungs and skin, but it can also affect other organs. Endothelial vinculin plays a critical role in angiogenesis regulation. Therefore, vinculin overexpression in SSc may give rise to anti-vinculin antibodies, which may contribute to the development of SSc vasculopathy. The current research aims to (1) determine whether anti-vinculin autoantibodies play a significant role in the diagnosis of SSc and (2) compare anti-vinculin serum levels between two scleroderma patient populations, namely, pulmonary artery hypertension (PAH)–predominant and interstitial pulmonary fibrosis (IPF)–predominant groups. Methods This research included 140 participants categorized into three groups: group I—patients with PAH-predominant; group II—patients with ILD-predominant; group III—the control group. Anti-vinculin antibodies were detected in serum samples collected from all participants using ELISA. All subjects underwent high-resolution computed tomography (CT), diffusing capacity for carbon monoxide, and pulmonary function tests. Results Patients in group I (PAH-predominant group, N = 35) were 41.3 [± 11.4] years old, with 80% being women. Patients in group II (ILD-predominant group, N = 35) were 41.0 [± 11.5] years old. The SSc group showed significantly higher anti-vinculin antibody levels than the control group (P < 0.001). The PAH-predominant group demonstrated significantly higher anti-vinculin antibody levels and anti-vinculin positivity than the ILD-predominant group. Conclusion Anti-vinculin antibodies in the blood appear to be diagnostic biomarkers for scleroderma. Furthermore, they shed light on some novel perspectives on the pathophysiology of specific lung fibrotic changes. Key Points• This study included two groups of systemic sclerosis patients (PAH-predominant group, ILD-predominant group) as well as a control group to investigate the significance of anti-vinculin antibodies in such cases.• Our results have demonstrated that anti-vinculin antibodies can play a significant role in diagnosing and monitoring systemic sclerosis disease.
inflammatory autoimmune disease with a frequency of 0.5–1.0% between the adult population of developed countries. It is marked by chronic inflammation of synovial tissue and accompianed by damage of the articular cartilage and adjecent bone, leading to substantial disability. Objectives: The aim of this study is to determine serum and synovial fluid levels of calprotectin in rheumatoid arthritis patients and to determine its relation with disease activity and severity. Methodology: This study was carried out on 40 rheumatoid arthritis patients who were admitted to Rheumatology, Rehabilitation and Physical Medicine Outpatient’ clinic and Inpatient Department of Benha University Hospital .Also Thirty age and sex matched( 28 females and 2 males ) apparently healthy volunteers were included in the study as a control group . All patients were assessed by full medical history, clinical examination, functional assessment, laboratory investigations including CBC, ESR ,CRP, liver functions, RF, Anticcp antibody, and Xrays were done to both hands. Serum and synovial levels of calprotectien were measured using the ELISA technique. Results: Serum levels of calprotectien were significantly higher in RA patients than healthy subjects [p<0.001], also there was a highly statistically significant increase in the mean synovial fluid calprotectin levels than mean serum calprotectien levels [p<0.001]. Local and systemic levels of calprotectin correlate with clinical, immunological and instrumental assessments of disease activity and the inflammatory degree of the joint. Conclusion: Calprotectin could be used as a new biomarker for monitoring the disease activity and severity of RA. Larger sets are needed to confirm the diagnostic and prognostic accuracy of calprotectin in RA
Background:Self-reactive antibodies are a characteristic of systemic lupus erythematosus [SLE]. These autoantibodies may attack any organ or tissue in the body causing organ failure. One class of anti-DNA antibodies, known as anti-DNA/N-methyl-D-aspartate receptor 2 [anti-DNA/NR2] antibodies, also interacts with the NR2 subunit [anti-NR2] of N-methyl-D-aspartate receptors [NMDARs]. Research suggests that anti-NMDAR antibodies contribute to the pathophysiology of SLE-related emotional and cognitive dysfunction.Objective:The goal of this study was to evaluate the prevalence and severity of systemic lupus erythematosus in individuals with anti-DNA/N-methyl-Daspartate receptor 2 [NR2] antibodies.Methodology: 60 SLE patients and 30 healthy controls had serum samples taken. Anti-NR2 antibodies in the serum were tested using an ELISA kit.Results: The average serum anti-NR2 antibody level in SLE patients was 34.10 ng/ml, whereas the level in healthy controls was only 11.60 ng/ml with a statistically significant difference [P<0.001].Serum anti-NR2 can significantlydiscriminate between SLE patients and healthy subjects, with diagnostic ability at best cut off value 13.26 ng/ml with high sensitivity and specificity.Conclusion:Serum anti-NR2 can be used as a new biomarker for SLE.
