Higher prevalence of fibromyalgia (FM) among chronic hepatitis-C virus (HCV) suspects virally-mediated pathway. To determine the frequency and clinical characteristics of FM in Egyptian patients with chronic HCV and to evaluate its relationship to viral load. 150 Egyptian patients with chronic HCV and 150 controls were included. Liver function tests, thyroid stimulating hormone (TSH), HCV antibodies, HCV-ribonucleic acid (RNA) and abdominal ultrasonography were done. FM was diagnosed according to 2010 American College of Rheumatology (ACR) classification criteria. The mean age of the patients was 54.1 ± 8.4 years and they were 94 females: 56 males; and the mean duration of HCV was 6.9 ± 3.2 years. Fatigue, arthralgia, arthritis, morning stiffness, weakness, sicca-like symptoms, depression, cognitive, sleep disturbances and irritable bowel syndrome (IBS) were significantly more frequent in HCV patients. Twenty six patients with HCV (17.3%) and 4 (2.7%) of the controls had FM. HCV patients with FM had significantly higher widespread pain index, symptom severity score, visual analogue scale (VAS), tender points count and stiffness than controls with FM. HCV patients with FM had significant higher VAS score, fatigue and depression than without FM. Rates of hematological features, autoantibodies, liver enzymes, abdominal US findings, patients with viral load > 800,000 IU/L were comparable. There is increased rate of fibromyalgia in chronic HCV patients and is associated with higher pain intensity, tender point count, symptom severity and fatigue. FM in patients with HCV infection is not related to viral load of HCV. [ABSTRACT FROM AUTHOR]

To assess serum level of CXCL12 in systemic lupus erythematosus (SLE) patients and to study its relation to clinical features, disease activity and damage. Forty SLE patients and 40 controls were included. SLE disease activity index (SLEDAI) and the damage index were assessed. Serum CXCL12 level was measured using ELISA and renal biopsy done. The mean age of the patients was 34.5 ± 10.4 years, disease duration 5 ± 5.2 years and were 38 females and 2 males (F:M 19:1). Renal biopsy was performed in 16 patients; 6 had inactive and10 active lupus nephritis (LN); 24 without signs suggestive of LN. Serum level of CXCL12 was significantly higher in patients (30.8 ± 16.9 ng/ml) than controls (20.2 ± 15.3 ng/ml) (p = 0.004). CXCL12 in patients with active LN (53.2 ± 25.3 ng/ml) was significantly elevated than those without LN (27 ± 12.5 ng/ml)(p < 0.001); and tended to be higher than those with inactive LN (34.2 ± 8.3 ng/ml)(p = 0.31). Levels were comparable between those with inactive LN and those without LN (p = 0.34). A significant correlation was found between serum CXCL12 and each of platelet count (p = 0.02), ANA titer (p = 0.007) and serum creatinine (p = 0.014). No significant correlations was found between CXCL12 and either SLEDAI (p = 0.59) or the damage index (p = 0.48). Alopecia was inversely associated with CXCL12 (p = 0.02). CXCL12 is a potential key-player for SLE development. Adding this test to ANA, serum creatinine, platelet count and renal biopsy findings may enhance their diagnostic capacity for lupus nephritis and can help in early management and prediction of its prognosis.

To assess health-related quality of life (HRQoL) and associated variables in Egyptian ankylosing spondylitis (AS) patients. 50 male patients with AS and 50 age-matched controls were enrolled. Clinical and laboratory data were examined including history for peripheral arthritis. Visual analog scale (VAS), Bath AS disease activity index (BASDAI), AS disease activity score (ASDAS)-C-reactive protein (CRP) and ASDAS-erythrocyte sedimentation rate (ESR) , Bath AS functional index (BASFI), Bath AS metrology index (BASMI) and AS quality of life (ASQoL). Spinal radiographs were graded by the modified Stoke AS spinal score (mSASSS). The mean age of the patients was 33.1 ± 7.4 years and disease duration of 6.8 ± 3.1 years. The mean ASQoL score in patients was significantly higher (9.4 ± 3.8; 3–15) compared to the control. 26 (52%) patients had peripheral arthritis. Of these, 17 (65.4%) had hip involvement, 6 (23.1%) had knee, 5 (19.2%) had shoulder affection and 3 (11.5%) had ankle joint involvement. Patients with peripheral joint involvement had significantly higher ASQoL score than those without (11.4 ± 3.1 and 7.3 ± 3.4 respectively, p < 0.001). ASQoL significantly correlated with BASMI (p = 0.048), BASFI (p = 0.02), BASDAI (p = 0.01), ASDAS.CRP (p = 0.02) and ASDAS.ESR (p = 0.01). The multiple regression analysis to identify the independent variables associated with the ASQoL showed a significant association with peripheral joint involvement, BASDAI, ASDAS.ESR, ASDAS.CRP and BASFI scores. AS is a chronic inflammatory disease that affects HRQoL especially with higher disease activity, functional disability, more peripheral joint involvement and lesser spinal mobility in Egyptian patients.

Abstract Background There is risk of premature atherosclerosis in juvenile idiopathic arthritis (JIA) patients which predisposes to cardiovascular disease (CVD) in adulthood. This can be assessed by flow mediated dilatation (FMD) and carotid intima media thickness (IMT) of the arterial wall and by soluble vascular cell adhesion molecule (sVCAM-1). Aim of the work To assess endothelial dysfunction in JIA children and to correlate sVCAM with FMD of brachial artery and carotid IMT. Patients and methods The study was conducted on 55 JIA patients. The following was assessed: body mass index (BMI), blood pressure, juvenile arthritis disease activity score (JADAS27). Childhood Health Assessment Questionnaire (C-HAQ), physical activity questionnaire (PAQ), fatigue assessment using The Pediatric Quality of Life (PedsQL) inventory, full blood count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), serum creatinine and lipid profile, sVCAM-1, FMD and IMT. Results The patients' age was 10.9 ± 3.9 years and were 28 (50.9%) females. JADAS-27 and CRP was higher in systemic JIA, but fatigue scores were significantly lower. CHAQ was significantly lower in patients with polyarticular disease. Patients with high disease activity had significantly younger age of onset, lower BMI, shorter disease duration, lower fatigue scale and physical activity scores and higher CHAQ. sVCAM-1 significantly correlated with CHAQ, low-density lipoprotein, CRP and ESR while FMD significantly correlated with PedsQL and PAQ. Conclusion JIA patients had impaired endothelial function and increased cIMT with increased sVCAM-1, impaired lipid profile, decreased physical activity and increased fatigue with a potentially higher cardiovascular risk in this pediatric population.

Abstract Background The diagnosis of early rheumatoid arthritis (RA) is challenging. B-cell chemokine (CXCL13) plays a critical role in the disease pathogenesis. Aim of the work To assess the diagnostic value of serum CXCL13 in early RA and compare it with rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies. Patients and methods The study included 60 RA patients; 30 early, 30 established RA and 30 healthy controls. The modified health assessment questionnaire (MHAQ), modified Sharp-van der Heijde score (MSS) and disease activity score (DAS28) were assessed in RA patients. RF, anti-CCP and serum level of CXCL13 were measured. Results Patients had a mean age of 39 ± 7.4 years and disease duration of 4.4 ± 5.7 years; they were 46 females and 12 males (F:M 3.8:1). Serum CXCL13 was significantly higher in early (191.7 ± 74.4 pg/ml) compared to established (136.4 ± 79 pg/ml) RA (p = 0.007) which were not observed with RF and anti-CCP; both were higher than in control (30.4 ± 13.5 pg/ml) (p < 0.001). In early RA, the frequencies of CXCL13, RF and anti-CCP positivity were 90%, 73.3% and 56.7% while in the established cases the frequencies were 36.7%, 66.7% and 63.3% respectively. CXCL13 significantly correlated with DAS28 (early: 0.49, p = 0.006; established: r = 0.38, p = 0.04) but not with MHAQ or MSS. The CXCL13 significantly correlated with both the RF and anti-CCP in both early and established cases (p < 0.001). Conclusion CXCL13 is an important for the diagnosis of early RA with a superior diagnostic performance compared to RF and anti-CCP. It may also be considered a potential biomarker of disease activity. [ABSTRACT FROM AUTHOR]
