Clinical and ultrasonographic evaluation of efficacy and safety of intralesional injection of autologous platelet-rich plasma in morphea: A comparative case series.

Objective: To evaluate the efficacy and safety of platelet-rich plasma to restore skin changes in morphea by ultrasound and Localized Scleroderma Cutaneous Assessment Tool. Methods: Nine morphea patients (21 lesions) were diagnosed clinically and by histopathology. Intradermal platelet-rich plasma was injected into morphea lesion once weekly for 12 sessions. The disease severity and damage were evaluated at baseline, after the last session (3 months later), and at 6 months follow-up using the LoSCAT and a high-resolution ultrasound. The healthy corresponding side was considered as a control. Results: The Localized Scleroderma Cutaneous Assessment Tool score showed a significant improvement starting from 13 ± 7.28 up to 7.33 ± 6.82 after the therapeutic endpoint, reaching to 6.44 ± 7.09 after 6 months of follow-up with p value = 0.008 and 0.014, respectively. There was a significant positive correlation between the duration of the lesion and the improvement assessed by the ultrasound, with p value = 0.01. Regarding adverse effects, all patients reported having pain during platelet-rich plasma injection; transient edema of the face was reported by four patients (45%), and only two patients showed transient erythema. Conclusion: Autologous platelet-rich plasma is a safe technique with great aesthetic outcomes for filling up the contour defects and correcting both hyper and hypopigmentation, in addition to softening the indurated lesions.

Clinical implications of seropositive and seronegative autoantibody status in rheumatoid arthritis patients: A comparative multicentre observational study.

Background and Objectives: Rheumatoid factor (RF) and anti-cyclic citrullinated protein (anti-CCP) have been used to improve the diagnosis and prognosis of rheumatoid arthritis (RA). However, their association with RA disease phenotypes, individually and in combination, is not well studied. The aim of the study was to compare patients' and disease characteristics, activity and severity in double seronegative (DNRA), single seropositive RF, single seropositive anti-CCP and double seropositive (DPRA) patients. Methods: Adults subjects with RA from Egyptian College of Rheumatology (ECR) database who had RF and anti-CCP results available were included. Demographic, clinical features, disease activity score 28 (DAS28), Health Assessment Questionnaire (HAQ) and laboratory data were collected and compared among different RA groups. Results: 5268 RA patients with mean age of 44.9±11.6 years, and 4477 (85%) were females. 2900 (55%) had DPRA, 892 (16.9%) had single positive RF, 597 (11.3%) had single positive anti-CCP while 879 (16.7%) had DNRA. Patients with DPRA had significantly high percentage of metabolic syndrome (19.3%, P < 0.001), and functional impairment using HAQ (P = 0.01). Older age (RRR [relative risk ratio]: 1.03, 95%CI: 1.0, 1.0, P = 0.029), greater DAS28 (RRR: 1.51, 95%CI: 1.2, 1.9, P < 0.001), higher steroid use (RRR: 2.4, 95%CI: 1.36, 4.25, P = 0.002) were at higher risk of DPRA while longer disease duration (RRR: 1.08, 95%CI: 1.01, 1.16, P = 0.017) and fibromyalgia syndrome (RRR: 2.54, 95%CI: 1.10, 5.88, P = 0.028) were associated with higher odds of single positive RF status. Conclusion: Dual antibody-positive status has higher disease activity and severity, and higher chance of development of metabolic syndrome; highlighting the implicated role of inflammation, atherogenesis and cardiovascular disease risk in RA.

Comparing the Efficacy of Local Corticosteroid Injection, Platelet-Rich Plasma, and Extracorporeal Shockwave Therapy in the Treatment of Pes Anserine Bursitis: A Prospective, Randomized, Comparative Study.

Background: Pes anserine bursitis (PAB) is one of the most common causes of painful knee syndromes. This study aimed at examining the efficacy of local corticosteroid injection, platelet-rich plasma (PRP) injection, and extracorporeal shock wave therapy (ESWT) as different modalities to alleviate pain and enhance function in patients with pes anserine bursitis (PAB). Methods: A prospective, randomized, comparative study was conducted on 180 patients diagnosed with chronic PAB. They were equally divided into three groups as follows: Group I received a local corticosteroid injection of 40 mg of methylprednisolone acetate/1 ml; Group II received a PRP injection; and in Group III, ESWT was used. Outcome measures included the visual analog scale (VAS), Western Ontario and McMaster Universities (WOMAC) pain score, WOMAC physical function score, and Ritchie articular index (RAI) for tenderness, which were recorded at the baseline, after 1 week, and after 8 weeks. Results: Before the application of procedures, there was a statistically significant increase in the WOMAC pain score in the local corticosteroid group compared to the PRP group and the ESWT group (P < 0.001). After the application of procedures, there was a statistically significant improvement in the 1-week and 8-week WOMAC pain score, WOMAC physical function score, and VAS in the local corticosteroid group in comparison to the PRP group and the ESWT group. (P < 0.001). Moreover, RAI for tenderness shows statistically significant improvement at 8 weeks in the local corticosteroid groups compared to the PRP groups (P < 0.001) and ESWT groups (P < 0.001). Similarly, a statistically significant difference was found between the PRP and ESWT groups (P=0.023). Conclusion: Our data suggest that in patients with PAB, local corticosteroid injection is more efficient than PRP injection and ESWT for reducing pain and enhancing function.

Ultrasound abnormalities of the major salivary glands in Egyptian patients with systemic sclerosis.

INTRODUCTION/OBJECTIVES: systemic sclerosis (SSc) is an autoimmune disorder with multiple organs destruction. This study aimed to identify the ultrasonographic changes of major salivary glands in Egyptian scleroderma patients and to detect their association to different disease manifestations. METHODS: Forty-seven SSc patients and 43 apparent healthy volunteers were enrolled. Demographics, inflammatory markers, and autoimmune status were recorded. Ultrasound evaluation of salivary glands was performed. Salivary gland changes' associations were statistically examined with SSc susceptibility and disease manifestations. RESULTS: Thirty-one SSc patients exhibited glandular pathology (p < 0.0001), compared to controls. Of these abnormalities, SSc patients showed a total parotid gray scale of 2, total submandibular gray scale of 2, total glandular gray scale of 4, and total glandular Doppler signal of 1 at p < 0.0001, compared to the control group. Patients with SSc and glandular pathology had a higher prevalence of arthritis (p = 0.029) and ESR (p = 0.002) than those with normal glandular ultrasound. Significant associations were reported between gray scale ultrasound (GSUS) of total parotid (odds ratio "OR" = 0.4), total submandibular (OR = 0.36), and total glandular (OR = 0.53) with susceptibility to SSc at p < 0.0001. Total glandular GSUS (p = 0.039) and total submandibular power Doppler (p = 0.044) correlated with the SSc duration. Total parotid GSUS (p = 0.008) and total glandular GSUS (p < 0.0001) correlated with Schirmer's test. CONCLUSIONS: Major salivary glands are affected in SSc. Hence, scanning these glands with ultrasound is an additive tool besides the current practice. Key Points • Major salivary gland changes, observed by ultrasonography, are new findings in Egyptian SSc patients. • Ultrasound changes of major salivary glands are associated with inflammatory markers and clinical manifestations of SSc. • Scleroderma ultrasonography scans of the main salivary glands could be added to the routine work.

Evaluating the Effect of Delayed Diagnosis on Disease Outcome in Fibromyalgia: A Multi-Center Cross-Sectional Study.

Background: The impact of delayed diagnosis (DD) on fibromyalgia (FM) patients' symptomatology and disease outcome has not yet been systematically studied. Objective: To analyze the predictors of DD and the influence of DD on FM aggravation and disease evaluation measures. Methods: 370 FM patients were interviewed prospectively for this study. The following information was obtained: DD, widespread pain index (WPI), symptom severity scale (SSS), polysymptomatic distress scale (PDS) scale (SSS + WPI), and tender points. We identified three groups of patients: early diagnosis (ED: 2 years; 83 patients), late diagnosis (LD: > 2-7 years; 198 patients), and very late diagnosis (VLD: > 7 years; 89 patients). Results: The patients' average age was 33.9 (9.8) years, and 79% were female. The SSS, PDS, and tender point means were 7.8 (1.6), 16.46 (4.1), and 14.31 (2.3), respectively. The correlation between DD and SSS (r = 0.14), the PDS scale (r = 0.37), and FM tender points (r = 0.16) was significant, but not with WPI (r = 0.06). When the three groups were examined, the SSS mean was 7.54 (1.6), 7.73 (1.4), and 8.25 (1.7), respectively (P 0.008), while the PDS mean was 15 (3.8), 15.95 (3.8), and 18.96 (4.4), respectively (P 0.008). (P 0.001). Conclusion: Early FM diagnosis is associated with lower SSS, total severity scale, and FM tender points, indicating a less severe condition.

Evaluating Gender Differences in Egyptian Fibromyalgia Patients Using the 1990, 2011, and 2016 ACR Criteria.

Background: Fibromyalgia (FM) is a common rheumatic illness distinguished by chronic pain, fatigue, cognitive problems, and functional disability. However, the differences between men and women have not yet been comprehensively studied, especially after the development of the last 2016 American College of Rheumatology (ACR) criteria. The aim of this study was to evaluate the gender differences in symptom characteristics, cognitive dysfunction, and disease severity in Egyptian FM patients considering both the ACR 1990, 2011, and the last 2016 ACR diagnostic criteria. Methods: This is a prospective cross-sectional study that was carried out on 352 patients with FM in the Rheumatology Department, Al-Azhar University Hospital in Egypt, in the period between January 1, 2020, and June 1, 2021. In addition to the number of tender points (TPC), data was collected on age, gender, body mass index (BMI), marital status, disease onset, duration, and diagnostic delay. The widespread pain index (WPI), the symptom severity scale (SSS), fatigue, cognitive dysfunction, sleep disturbance, awakening unrefreshed, headache, abdominal pain, and depression were evaluated and scored according to 2010 and 2016 ACR criteria. A visual analog scale (VAS) for pain, fatigue, stiffness, anxiety, and depression is included in the questionnaire. The total score ranges were produced using total score ranges ranging from 0 to 80 (excluding job items), with higher scores indicating a stronger negative effect and/or intensity of symptoms. The polysymptomatic distress scale (PDS) has been calculated by the summation of the SSS with the WPI. The Revised FM impact questionnaire (FIQR) has also been evaluated. Results: The study shows that females have a significantly higher prevalence of fatigue, cognitive dysfunction, sleep disturbance, headache, and abdominal pain (p < 0.05). Also, females showed significantly higher scores than males regarding WPI, SSS, and mean TPC (p = 0.004, 0.027, and 0.001, respectively). While there was no difference regarding the FIQR (p=0.93), PDS was significantly higher in women (p= 0.001). Conclusion: Female patients with FM had greater disease severity scores, symptomatology, and number of tender points. Whatever the criteria applied, the prevalence and intensity of the disease features are higher in females, which may underestimate the disease in male patients.

Rheumatologists' knowledge and perception of COVID-19 and related vaccines: the vaXurvey2 online survey.

The study aimed to explore the experience of coronavirus disease-2019 (COVID-19) infection and vaccine adverse events (AEs) among rheumatologists. A validated questionnaire was distributed as a Google form to rheumatologists across the country via social networking sites from late December 2021 till early January 2022. The questionnaire included questions regarding participants' socio-demographic details, COVID-19 infection and vaccination details with special emphasis on AEs. Out of 246 responses, 228 were valid. 200 (81.3%) responders had received the vaccine. The mean age of the 228 participants was 37.9 ± 8.5 years, 196 were females and 32 males (F:M 6.1:1) from 18 governorates across the country. Comorbidities were present in 54 subjects (27%). There was a history of highly suspicious or confirmed COVID-19 infection in 66.7% that were all managed at home. The COVID-19 vaccine was received by 200 and a booster dose of 18.5%. Obesity and musculoskeletal involvement co-morbidities were present only in those with AEs (9.1% and 5.5% respectively). AEs were present in 82%; 66.7% had injection-site tenderness, 50% fatigue, 35.5% fever, 15% chills, 42.5% myalgia, 14.5% arthralgia, 8% low back pain, headache 31%, dizziness 10%, sleepliness 16% and 15% developed post-vaccine. There were no differences according to the geolocation regarding the occurrence of COVID-19 infection (p = 0.19) or AEs post-vaccine (p = 0.58). The adverse events were mostly mild to moderate and tolerable which makes this work in agreement with other studies that support the broad safety of the vaccine in favor of the global benefit from mass vaccination.

Aging and entheses: An ultrasonographic probing of degenerative enthesopathy in a cohort of 147 healthy subjects.

AIM: To investigate the prevalence and features of degenerative enthesopathic changes in a large cohort of healthy individuals by musculoskeletal ultrasound (MSUS) and their relation to age and other demographic features. METHODS: In this cross-sectional study, 147 healthy subjects (1470 entheses) were examined by MSUS according to the Outcome Measures in Rheumatology guidelines: Achilles tendon, plantar fascia, patellar, and quadriceps insertions of both lower limbs. RESULTS: The mean age (±SD) of the participants was 43.68 (±14.53) years and 57.1% were female. Enthesopathy has been detected in at least 1 area in 113 subjects (76.87%). Thickening (21.6%) and hypoechogenicity (15.3%) were the most frequent inflammatory findings while enthesophyte (10.13%) was the most prevalent structural one. Age and male gender were significantly correlating with inflammatory (rs  = .341, P = .001/r = .310, P = .001), structural (rs  = .354, P = .001/r = .166, P = .04) and total scores (rs  = .406, P = .001/r = .302, P = .001). More inflammatory changes were noticed in the age group 36-55 years. Body mass index had a positive correlation with inflammatory (rs  = .290, P = .001) and total scores (rs  = 0.298, P = .001) but not with structural lesions (rs  = .154, P = .062). CONCLUSIONS: Thickening, hypoechogenicity, cortical irregularities, and enthesophytes are frequent degenerative features of enthesopathy. These findings need to be redefined to be more specific for spondyloarthritides. Enthesopathy should be interpreted with caution in the light of the clinical picture, especially in elderly and obese male patients.

The effect of Helicobacter pylori seropositivity and activity on disease outcome in patients with rheumatoid arthritis, systemic lupus erythematosus and ankylosing spondylitis.

The association between infection with Gram-negative bacteria and autoimmune diseases has been investigated with controversies about the role of the organisms especially, Helicobacter pylori (H. pylori). To evaluate the impact of the presence and activity of H. pylori on the disease activity in patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and ankylosing spondylitis (AS). This study was carried out on one hundred adult patients and 50 controls. Patients included 40 RA, 40 SLE, and 20 AS. Participants were subjected to clinical examination and laboratory investigations; ESR (spectrophotometric assay), CRP (turbidimetric method), serum H.pylori IgG antibody test (enzyme immunoassay), and H. pylori antigen test (lateral flow immunoassay, rapid one-step test) in stool. Positive test in stool indicated active current H. pylori infection. Mean age of patients was 36.95±10.34; 51.2±6.91, 35.5±3.71, and 48.82±5.81 in SLE, RA, AS, and control groups respectively. Serum H. pylori IgG antibodies was 0.803±0.497 U/mL in SLE group, 1.48±0.637 U/mL in RA group and 0.75±0.68 U/mL in AS group while it was 0.2±0.61U/mL in the control group with a significant difference (P=0.000). The H. pylori antigen in stool was found positive in 30%, 70% and 20% of patients of the three groups respectively while it was positive in 10% of the control group with P>0.001. Patients with active SLE (SLEDAI >3) and RA (DAS-28 >3.2) demonstrated higher frequency of positive test for H. pylori antigen in stool than patients at remission (66.7% P= 0.02 and 83.3% P= 0.01 respectively). In contrast, 22.2% of patients with active AS (BASDAI > 4) were positive for H. pylori in stool. In conclusion, H. pylori infection is associated with increased disease activity in patients with SLE and RA but not AS.

Macrophage activation syndrome triggered by systemic lupus erythematosus flare: successful treatment with a combination of dexamethasone sodium phosphate, intravenous immunoglobulin, and cyclosporine: a case report.

BACKGROUND: Macrophage activation syndrome is classified as a secondary form of hemophagocytic lymphohistiocytosis. It is a hyperinflammatory complication observed to be comorbid with a variety of autoimmune diseases, including adult-onset Still's disease and systemic juvenile idiopathic arthritis. Macrophage activation syndrome is less commonly detected in adult patients with systemic lupus erythematosus, which, if untreated, can be fatal, though determining the optimum treatment strategy is still a challenge. CASE PRESENTATION: Herein, we report a case of macrophage activation syndrome in a 33-year-old Egyptian female as an unusual complication of a systemic lupus erythematosus flare in adult patients. Our patient was initially treated with a combination of intravenous methylprednisolone pulse therapy and intravenous immunoglobulin therapy, which was followed by a course of oral prednisolone and oral cyclosporine with little response. Switching from oral prednisone to intravenous dexamethasone sodium phosphate showed a more favorable clinical and biochemical response. CONCLUSION: Macrophage activation syndrome is less commonly detected in adult patients with systemic lupus erythematosus. Our case demonstrates that dexamethasone sodium phosphate can be a successful alternative treatment for patients with systemic lupus erythematosus complicated by macrophage activation syndrome in whom the response to pulse methylprednisolone was inadequate to manage their illness, proving to be remarkably effective in a relatively short time frame.
