Anti-vinculin antibodies as a novel biomarker in Egyptian patients with systemic sclerosis.

Clin Rheumatol 2022 Jul 25. Epub 2022 Jul 25.

Faculty of Medicine, Benha University, Benha, Al-Qalyubia Governorate, Egypt.

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.

Correlations between ultrasonographic findings, clinical scores, and depression in patients with knee osteoarthritis.

Eur J Rheumatol 2017 Sep 20;4(3):205-209. Epub 2017 Jun 20.

Department of Rheumatology, Rehabilitation & Physical Medicine, Benha University School of Medicine, Benha, Egypt.

Objective: This study aimed to explore correlations between the presence of depression, clinical scores, and ultrasonographic (US) grading in osteoarthritis (OA) patients and to clarify if depressive symptoms might cause a discrepancy between US findings and clinical scores.

Material And Methods: Two hundred patients with primary knee OA and 100 healthy hospital volunteers of the same age and sex not complaining of knee troubles participated in this study. We evaluated depressive symptoms in all participants using the Beck Depression Inventory (BDI) scale. Thorough clinical examination was performed, including assessment using the Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) for disability. All patients underwent US examination of their affected knees.

Results: Depression was detected in 60 patients with knee OA (30%) and in 5 controls (5%). The mean of BDI score was 12.8±12.2 in OA patients and 5.8±3.2 in controls, and this difference was statistically significant (p=0.03). Correlations of BDI with both body mass index (BMI) (p=0.04) and Numerical Rating Scale of Pain (NRSP) score (p=0.006) were significant, while correlations of BDI with both the ages of our patients (p=0.74) and their disease duration (p=0.88) were insignificant. There were statistically significant correlations between patients' disease duration and US measurements regarding osteophyte length, lateral femoral cartilage thickness, medial femoral cartilage thickness, and thickness of the quadriceps tendon despite of the presence of insignificant correlations between disease duration and both the effusion volume and volume of Baker's cysts. There were statistically significant correlations between patients' disease duration and US measurements except for effusion volume and volume of Baker's cysts. There were statistically significant correlations between the NRSP score in OA patients and BDI (p=0.006) and all US measurements apart from lateral femoral cartilage thickness, medial femoral cartilage thickness, and thickness of quadriceps tendon. There were statistically significant correlations between BDI in OA patients and the WOMAC (p=0.005), Kellgren-Lawrence (KL) grading (p=0.034), and US grading (p=0.041).

Conclusion: The presence of knee effusion, Baker's cysts, osteophytes, and high BMI have a great impact on the pain and disability associated with OA. Higher clinical scores, radiographic scores, and US scores correlate with the emergence of depression in OA patients.

Decrease of serum biomarker of type II Collagen degradation (Coll2-1) by intra-articular injection of an autologous plasma-rich-platelet in patients with unilateral primary knee osteoarthritis.

Eur J Rheumatol 2017 Jun 1;4(2):93-97. Epub 2017 Jun 1.

Department of Clinical and Chemical Pathology, Benha University School of Medicine, Benha, Egypt.

Objective: This study aimed to evaluate the effect of one dose of intra-articular injection of (PRP) in the knee joint on a specific osteoarthritis (OA) serum biomarker of cartilage degeneration, Collagen 2-1 (Coll2-1), over a short period of 3 months. The aim extended to clarify the effect of PRP on the functional status of the osteoarthritic knee joint.

Material And Methods: Sixty patients with primary unilateral knee OA were enrolled in this study. They were subdivided according to Kellgren-Lawrence grading scale (KL) into (Group I): including patients with KL grade < 3 and (Group II): including patients with KL grade ≥3. Patients were asked to complete the Western Ontario and McMaster Universities Arthritis Index (WOMAC) Score. PRP was prepared and injected immediately into the affected knee. Serum Coll2-1 (S.Coll2-1) concentration was measured by enzyme-linked immunosorbent assay (ELISA) kit pre and 3 months after PRP injection.

Results: Significant reduction in S.Coll2-1 concentration in primary knee OA patients; (p<0.001) and (p<0.05) in group I and group II respectively as well as significant improvements in WOMAC total and WOMAC sub-scores values were noted after single intra-articular PRP injection with maximal functional improvements were achieved after 3 months (p<0.001). Mild cases experienced favorable results with no remarkable adverse reactions were observed.

Conclusion: Reduction in specific OA biomarker S.Coll2-1 following intra-articular PRP injection emphasize that PRP could be a promising safe and tolerable effective therapeutic option which improves function from basal states in primary knee OA patients.

Serum calreticulin as a novel biomarker of juvenile idiopathic arthritis disease activity.

Eur J Rheumatol 2017 Mar 1;4(1):19-23. Epub 2017 Mar 1.

Deaprtment of Diagnostic Radiology, Benha University School of Medicine, Benha, 9Egypt.

Objective: This study aimed to investigate the relations between calreticulin (CRT) serum level and both disease activity and severity parameters in juvenile idiopathic arthritis (JIA).

Material And Methods: In this study, 60 children with JIA and 50 age-and-sex-matched healthy subjects were enrolled. The assessment of the disease activity was done using juvenile arthritis disease activity score 27 (JADAS-27). The assessment of disease severity was done via gray-scale ultrasonography (US) and power Doppler US (PDUS). Enzyme-linked immunosorbent assay (ELISA) was used to assay the serum level of human CRT.

Results: The mean serum CRT levels in JIA patients was 8.6±1.2 ng/mL and showed a highly significant increase (p=0.001) as compared to the mean serum levels in the controls (5.02±0.77 ng/mL). There were statistically significant positive correlations between the serum CRT levels and disease duration, tender joint count, swollen joint count, visual analog scale, erythrocyte sedimentation rate, JADAS-27, C-reactive protein, rheumatoid factor titer, and ultrasonographic grading for synovitis and neovascularization.

Conclusion: Elevated serum CRT levels in JIA patients and its correlations with JIA disease activity and severity parameters signified that CRT might be used as a novel biomarker for disease activity and severity in JIA.
