ABSTRACT

Morphea, also known as localized scleroderma, is an inflammatory sclerosing disorder of uncertain pathogenesis that affects the skin and underlying tissues. In the pediatric population, the disease often runs a chronic course with a high risk for irreversible sequelae; as such, patients often require long-term monitoring. The objective of this study is to develop a multi-center, consensus-based electronic medical record template for pediatric morphea patient visits using a modified Delphi method of iterative surveys. By facilitating consistent data collection and interpretation across medical centers and patient populations, this template may improve patient care for pediatric patients with morphea.

ABSTRACT

Systemic sclerosis (SSc), also called scleroderma, is an auto-immune rheumatic disease that is characterized by fibrosis of the skin and internal organs and vasculopathy. Three of the severe manifestations of the disease include a scleroderma renal crisis (SRC), pulmonary arterial hypertension, and digital ulceration. Vascular manifestations like Raynaud's phenomenon are an almost universal symptom in patients with SSc and are often the earliest manifestation of the disease. An SRC occurs in approximately 10% of all patients with scleroderma. It is characterized by malignant hypertension and progressive renal failure. However, about 10% of SRC cases present with normal blood pressure or a normotensive renal crisis. A 65-year-old man with a history of peripheral vascular disease and newly diagnosed heart failure presented to the emergency department on account of progressive discoloration of the left big toe and intermittent confusion. Initially, he was noted to be hemodynamically stable, with bluish discoloration of his left lower extremity and left big toe, which was tender to palpation with palpable distal pulses. His left toe progressively became dusky and gangrenous, necessitating ray amputation by vascular surgery. His hospital course was further complicated by worsening acute kidney injury, requiring initiation of hemodialysis, and progressive hypoxia with the transition from room air to high-flow oxygen. As part of his workup for acute kidney injury (AKI), his antinuclear antibody (ANA) was found to be positive, with high titers, as well as elevated SCl-70 IgG. Despite the initiation of hemodialysis, and post-surgical revision, he continued to deteriorate. His family opted for comfort care measures, and he died a few days later. Although SSc is a rare disease, it is associated with significant morbidity and has one of the highest mortality rates among connective tissue diseases. SSc can present with heterogeneous manifestations, mimicking several isolated organ-specific conditions. This makes the diagnosis challenging, especially early in the course of the disease. A high index of suspicion, especially in the setting of rapidly progressing multi-organ involvement without a clear cause, should prompt further evaluation of systemic sclerosis.

ABSTRACT

A 50-year-old patient with a history of limited cutaneous scleroderma began with polyarthralgia (left shoulder, elbows and hips) without stiffness or associated inflammatory syndrome. Treatment with oral anti-inflammatory drugs was started on suspicion of peripheral spondyloarthritis with partial response. This progressed with the appearance of stiffness and functional limitation of the hips as well as an increase in the inflammatory syndrome two weeks after onset. It was decided to perform an 18F-FDG-PET scan compatible with polymyalgia rheumatica. The patient was treated with oral corticosteroids with an excellent response after one week of treatment. LEARNING POINTS: Polymyalgia rheumatica should be considered, even in young adults, with atypical clinical presentation.Post-infectious and paraneoplastic inflammatory rheumatism should be ruled out before considering the diagnosis of polymyalgia rheumatica.18F-FDG-PET plays an important role in the positive diagnosis of PMR and in the differential diagnosis.

ABSTRACT

BACKGROUND: Systemic sclerosis (SSc) is a rare chronic autoimmune disease with heterogeneous manifestations. In the last decade, several clinical trials have been conducted to evaluate new treatment options for SSc. The purpose of this work is to update the recommendations of the Brazilian Society of Rheumatology in light of the new evidence available for the pharmacological management of SSc. METHODS: A systematic review including randomized clinical trials (RCTs) for predefined questions that were elaborated according to the Patient/Population, Intervention, Comparison, and Outcomes (PICO) strategy was conducted. The rating of the available evidence was performed according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. To become a recommendation, at least 75% agreement of the voting panel was needed. RESULTS: Six recommendations were elaborated regarding the pharmacological treatment of Raynaud's phenomenon, the treatment (healing) and prevention of digital ulcers, skin involvement, interstitial lung disease (ILD) and gastrointestinal involvement in SSc patients based on results available from RCTs. New drugs, such as rituximab, were included as therapeutic options for skin involvement, and rituximab, tocilizumab and nintedanib were included as therapeutic options for ILD. Recommendations for the pharmacological treatment of scleroderma renal crisis and musculoskeletal involvement were elaborated based on the expert opinion of the voting panel, as no placebo-controlled RCTs were found. CONCLUSION: These guidelines updated and incorporated new treatment options for the management of SSc based on evidence from the literature and expert opinion regarding SSc, providing support for decision-making in clinical practice.

ABSTRACT

Stabilin-1 (Stab1) and Stabilin-2 (Stab2) are scavenger receptors expressed by liver sinusoidal endothelial cells (LSECs). The Stabilin-mediated scavenging function is responsible for regulating the molecular composition of circulating blood in mammals. Stab1 and Stab2 have been shown to influence fibrosis in liver and kidneys and to modulate inflammation in atherosclerosis. In this context, circulating and localized TGFBi and POSTN are differentially controlled by the Stabilins as their receptors. To assess Stab1 and Stab2 functions in inflammatory and fibrotic skin disease, topical Imiquimod (IMQ) was used to induce psoriasis-like skin lesions in mice and Bleomycin (BLM) was applied subcutaneously to induce scleroderma-like effects in the skin. The topical treatment with IMQ, as expected, led to psoriasis-like changes in the skin of mice, including increased epidermal thickness and significant weight loss. Clinical severity was reduced in Stab2-deficient compared to Stab1-deficient mice. We did not observe differential effects in the skin of Stabilin-deficient mice after bleomycin injection. Interestingly, treatment with IMQ led to a significant increase of Stabilin ligand TGFBi plasma levels in Stab2-/- mice, treatment with BLM resulted in a significant decrease in TGFBi levels in Stab1-/- mice. Overall, Stab1 and Stab2 deficiency resulted in minor alterations of the disease phenotypes accompanied by alterations of circulating ligands in the blood in response to the disease models. Stabilin-mediated clearance of TGFBi was altered in these disease processes. Taken together our results suggest that Stabilin deficiency-associated plasma alterations may interfere with preclinical disease severity and treatment responses in patients.

ABSTRACT

Objectives: To determine the effect of disease activity on clinical outcomes of coronavirus disease-2019 in patients with rheumatic diseases. METHODS: The prospective, cohort study was conducted from January 1st to June 30th, 2021, at Rheumatology department, Fauji Foundation Hospital, Rawalpindi. It comprised patients of rheumatic disorders who were affected by coronavirus disease-2019. The patients were categorised according to rheumatic disease activity into remission group I, low disease activity group II, moderate group III and high-activity group IV. Coronavirus disease-2019 outcomes compared included recovered vs death, hospitalisation yes vs no, mechanical ventilation yes vs no. The association of disease activity status with coronavirus disease-2019 outcomes was explored. Data was analysed using SPSS 23. RESULTS: Of the 100 patients, 78(78%) were females and 22(22%) were males. The overall mean age was 45.60±13.7 years. There were 23(23%) patients in group I, 42(42%) patients in group II, 21(21%) patients in group III and 14(14%) patients in group IV. Overall,17(17%) patients died and 83(83%) patients survived. In group III, 7(33.3%) patients died, followed by 6(42.9%) in group IV (p<0.05). In total, 7(7%) patients needed mechanical ventilation, with 3(21.4%) being in group IV (p<0.05). Hospitalisation was needed in 33(33%) cases, and intergroup comparison was non-significant (p>0.05). CONCLUSIONS: Patients with severe rheumatic autoimmune disease affected by coronavirus disease-2019 were more likely to die and require invasive ventilation.

ABSTRACT

Purpose: Scleroderma is a multisystemic disorder characterised by inflammatory and vascular anomalies, and excess fibrosis. Progressive systemic sclerosis (PSS) mainly progresses with skin, joint, lung, heart, and kidney involvement. Involvement of cerebral vessels is rare in both localised scleroderma and PSS. Transient ischemic attack and stroke are rare complications of scleroderma. Case description: We present a 60-year-old stroke patient with localised scleroderma presenting with impaired speech, forgetting words, and occasional temporary memory loss. Comment: In the case we present, no pathology was found in the clinical and laboratory tests performed in terms of ischemic risk factors. Skin findings included contracture, skin biopsy results, and antibody positivity related to scleroderma. Given the current pathogenesis of scleroderma, the patient was suspected of having a stroke.

ABSTRACT

This case report details a rare presentation of diffuse scleroderma, where a 38-year-old female developed hypertensive encephalopathy due to scleroderma renal crisis (SRC). SRC, characterized by sudden severe hypertension and renal failure, poses a life-threatening emergency. The patient's clinical features, including skin changes and abnormalities on nailfold capillaroscopy, facilitated the diagnosis of diffuse scleroderma. Comprehensive diagnostic investigations revealed multisystem involvement. Management involved angiotensin-converting enzyme inhibitors, hydroxychloroquine, and packed red cell transfusions, highlighting a holistic therapeutic approach. This case underscores the importance of recognizing diverse scleroderma manifestations in hypertensive emergencies for timely intervention and improved outcomes.

ABSTRACT

Trace elements are essential for several physiological processes. To date, various data have suggested that inadequate levels of trace elements may be involved in the pathogenesis of different chronic diseases, including immune-mediated ones, or may develop during their course. Systemic sclerosis (SSc) is a complex autoimmune multisystemic disease, primarily characterized by microvascular dysregulation, the widespread activation of the immune system and tissue fibrosis. According to the latest reports regarding the pathogenesis of SSc, the main pathophysiological processes-inflammation, vasculopathy and fibrosis-may include various trace element derangements. The present literature review aims to update the available data regarding iron, zinc, copper and selenium status in SSc as well as to underline the possible implications of these trace elements in the complexity of the pathogenic process of the disease. We observe that the status of trace elements in SSc plays a crucial role in numerous pathogenic processes, emphasizing the necessity for proper monitoring and supplementation. The reported data are heterogenous and scarce, and future studies are needed in order to draw clearer conclusions about their complete spectrum.

ABSTRACT

Connective tissue represents the support matrix and the connection between tissues and organs. In its composition, collagen, the major structural protein, is the main component of the skin, bones, tendons and ligaments. Especially at the pediatric age, its damage in the context of pathologies such as systemic lupus erythematosus, scleroderma or dermatomyositis can have a significant negative impact on the development and optimal functioning of the body. The consequences can extend to various structures (e.g., joints, skin, eyes, lungs, heart, kidneys). Of these, we retain and reveal later in our manuscript, mainly the respiratory involvement. Manifested in various forms that can damage the chest wall, pleura, interstitium or vascularization, lung damage in pediatric systemic inflammatory diseases is underdeveloped in the literature compared to that described in adults. Under the threat of severe evolution, sometimes rapidly progressive and leading to death, it is necessary to increase the popularization of information aimed at physiopathological triggering and maintenance mechanisms, diagnostic means, and therapeutic directions among medical specialists. In addition, we emphasize the need for interdisciplinary collaboration, especially between pediatricians, rheumatologists, infectious disease specialists, pulmonologists, and immunologists. Through our narrative review we aimed to bring up to date, in a concise and easy to assimilate, general principles regarding the pulmonary impact of collagenoses using the most recent articles published in international libraries, duplicated by previous articles, of reference for the targeted pathologies.

ABSTRACT

The pathogenesis of immunoinflammatory rheumatic diseases (IRDs) is based on chronic inflammation, one of the key mechanisms of which may be abnormal activation of macrophages, leading to further disruption of the immune system. OBJECTIVE: . The objective of this study was to evaluate the proinflammatory activation of circulating monocytes in patients with IRDs. MATERIALS AND METHODS: . The study involved 149 participants (53 patients with rheumatoid arthritis (RA), 45 patients with systemic lupus erythematosus (SLE), 34 patients with systemic scleroderma (SSc), and 17 participants without IRDs) 30 to 65 years old. Basal and lipopolysaccharide (LPS)-stimulated secretion of monocytes was studied in a primary culture of monocytes obtained from blood by immunomagnetic separation. Quantitative assessment of the cytokines tumor necrosis factor α (TNF-α), interleukin 1ß (IL-1ß), as well as the chemokine monocyte chemoattractant protein-1 (MCP-1) was carried out in the culture fluid by ELISA. Proinflammatory activation of monocytes was calculated as the ratio of LPS-stimulated and basal secretions. RESULTS: . It was shown that the basal secretion of all studied cytokines was significantly increased in all groups of patients with IRDs, except for the secretion of IL-1ß in the SLE group, compared to the control. LPS-stimulated secretion of TNF-α was increased and MCP-1 was decreased in patients with IRDs compared to the control group; LPS-stimulated IL-1ß secretion only in the SSc group significantly differed from the control group. In the RA group, monocyte activation was reduced for all cytokines compared to the control; in the SLE group, for TNF-α and MCP-1; in the SSc group, for MCP-1. CONCLUSIONS: . The decrease in proinflammatory activation of monocytes in patients with IRDs is due to a high level of basal secretion of cytokines, which can lead to disruption of the adequate immune response in these diseases and is an important link in the pathogenesis of chronic inflammation.

ABSTRACT

Cardiac magnetic resonance imaging (CMR) is the gold-standard non-invasive method of assessing cardiac structure and function, including tissue characterisation. In systemic sclerosis (SSc), heart involvement (SHI) is a leading cause of mortality yet remains poorly understood. SHI is underestimated by conventional echocardiography, and CMR provides an important opportunity to better identify and quantify subtle myocardial changes including oedema and fibrosis. This review summarises current CMR techniques, the role of CMR in SSc and SHI, and the opportunities to further our understanding of its pathogenesis and management.

ABSTRACT

Background and Objectives: Left ventricular systolic dysfunction (LVSD) is a cardiac involvement that is the leading cause of death among patients with systemic sclerosis (SSc). We aimed to define the clinical course and predictors of LVSD among SSc patients. Methods: We conducted a cohort study among adult patients with SSc who were followed up from 2013 to 2020. Semiparametric Cox regression analysis with robust clustering by cohort identification number was used to evaluate the predictors of LVSD. Results: Among the 3, 987 person-years, LVSD was defined in 35 of 419 SSc patients for an incidence of 0.88 per 100 person-years. The median duration of the disease was 8.5 (interquartile range (IQR) 4.9-12.9) years. Every 1-point increase in the modified Rodnan skin score (mRSS) and salt and pepper skin were strong predictors of LVSD, with a respective adjusted hazard ratio (HR) of 1.05 and 3.17. During follow-up, 26 cases (74.3%) had unimproved LVSD. The strong predictors of the unimprovement of LVSD were every 1-point increase in mRSS (HR 1.05), every 1 mg increase in prednisolone treatment (HR 1.05), and every 1 U/L increase in creatine kinase (CK) (HR 1.001). Mycophenolate treatment was a protective factor against the unimprovement of LVSD in SSc (HR 0.15). Conclusions: LVSD was frequently found in patients with diffuse cutaneous SSc, and in most cases, it remained unimproved during follow-up. High mRSS, steroid use, and high CK levels were predictors of unimproved LVSD, whereas mycophenolate treatment might prevent the progression of LVSD. Steroids should be prescribed with caution in patients with longer disease duration.

ABSTRACT

Background and Objectives: The clinical course, the outcomes of myocarditis, and the imaging progression of cardiac magnetic resonance imaging (MRI) in systemic sclerosis (SSc) are still unknown. We aimed at defining changes in cardiac MRI findings, the clinical course, and the outcomes of SSc patients previously defined as having myocarditis by cardiac MRI. Methods: This prospective cohort study included SSc patients, who had previously been diagnosed with myocarditis through cardiac MRI at the Scleroderma Clinic of Khon Kaen University, between 2018 and 2020 and had had annual follow-ups of cardiac MRI for at least 3 years. Data on demographics, clinical characteristics, cardiac MRI findings, treatment regimens, and outcomes were collected. Serial cardiac MRI on a yearly basis was analyzed to assess changes in myocardial involvement over the 3-year period. Results: Ten SSc patients diagnosed with myocarditis via cardiac MRI were included. Most belonged to the diffuse cutaneous subset with a mean age of 58.3±8.6 years and were mildly symptomatic. Initial cardiac MRI findings showed myocardial edema and hyperemia in all patients and eight patients had had pre-existing myocardial scars, suggesting disease chronicity. Treatment for concomitant interstitial lung disease involved steroids with either cyclophosphamide or mycophenolate mofetil in 6 patients. Outcomes of myocarditis were stable, improving, and worsening in 4, 4, and 2 patients, respectively. There was no complete resolution of the cardiac MRI indices for myocarditis, and none had had major cardiac events. Conclusion: Although SSc myocarditis on cardiac MRI may improve or show stability, the changes remained persistent. Among patients with SSc and mildly symptomatic myocarditis, the efficacy of steroids and immunosuppressive therapy is inconclusive. Over a 3-year follow-up, the prognosis had been acceptably good with no cardiac events.

ABSTRACT

Primary heart involvement (pHI) is frequent in systemic sclerosis (SSc), even though often underdiagnosed. SSc-pHI has been recently defined as cardiac abnormalities that are predominantly attributable to SSc rather than other causes and/or complications. SSc-pHI represents a major determinant of mortality in SSc, accounting alone for about 12% of disease-related deaths; its early recognition and promptly therapeutic interventions are therefore crucial. Both perfusion defects and myocardial inflammation contribute to the occurrence of myocardial fibrosis that precipitates myocardial remodeling, potentially leading to heart failure and arrhythmic complications. To date, clear evidence and guidelines for effectively managing SSc pHI are not established yet, resulting in a lack of a defined therapeutic algorithm. In this review we summarize the most recent scientific literature on the prevailing therapeutic strategies and interventions to manage SSc-pHI, with particular focus on therapeutic strategies to counteract the 3 major pathogenic events of the disease, i.e. microvascular damage, myocardial inflammation and myocardial fibrosis.

ABSTRACT

Juvenile systemic sclerosis (JSSc) is a rare autoimmune disorder that primarily affects children and adolescents. It is thought to be caused by a confluence of immunological, environmental, and genetic variables. The disease is characterized by excessive collagen production. It can result in symptoms such as shortness of breath, chest pain, difficulty swallowing, high blood pressure, and kidney problems. Although calcinosis cutis is common in systemic sclerosis, it is very rare in JSSc. We report the case of a 14-year-old female who presented with complaints of breathlessness for four days and multiple lesions in the sacral region for two months. She underwent surgical excision for calcinosis cutis in dependent regions. Early diagnosis and treatment of the condition are of immense importance in preventing mortality.

ABSTRACT

BACKGROUND: To date, there are no accepted outcome measures to monitor morphea, and consensus on specific monitoring criteria for morphea remains elusive. A few studies have assessed the criterion validity of skin ultrasound in morphea. So, in this study, we approach ultrasound findings in morphea lesions. MATERIAL AND METHODS: This was a retrospective-analytical study conducted between December 2021 and May 2023. Patients were clinically evaluated at a dermatology outpatient clinic and then referred for high-frequency ultrasound (HF-US) evaluation and were selected to be included in this study. The lesions were confirmed by histopathology as well. Sonographic evaluations were performed on the lesion site and the symmetrical uninvolved other side. Dermal thickness and dermal echogenicities were recorded. Statistical analysis of group differences was performed by using the 2-tailed Student t-test. A p-value of less than 0.05 was considered statistically significant. RESULTS: Forty-one morphea lesions in the inflammatory phase of 27 patients were included in the study. The mean dermal thickness of morphea lesions was 1107.97 ± 414.3 and the mean dermal thickness of the control side was 1094.65 ± 331.06, The difference between these two variables was not statistically significant. The mean dermal density of lesions was 49.13 ± 18.97 and the mean dermal density of the control side was 52.22 ± 25.33. The difference between these two variables was not statistically significant. CONCLUSION: This study shows that HF-US indicated increasing dermal thickness and reducing the dermal density of the morphea lesions in the inflammatory phase confirmed with the histopathology.

ABSTRACT

OBJECTIVE: Symptoms of anxiety increased early in the COVID-19 pandemic among people with systemic sclerosis (SSc) then returned to pre-pandemic levels, but this was an aggregate finding and did not evaluate whether vaccination may have contributed to reduced anxiety symptom levels. We investigated whether being vaccinated for COVID-19 was associated with reduced anxiety symptoms among people with SSc. METHODS: The longitudinal Scleroderma Patient-centered Intervention Network (SPIN) COVID-19 Cohort was launched in April 2020 and included participants from the ongoing SPIN Cohort and external enrollees. Participants completed measures bi-weekly through July 2020, then every 4 weeks afterwards through August 2022 (32 assessments). We used linear mixed models to evaluate longitudinal trends of PROMIS Anxiety 4a v1.0 anxiety domain scores and their association with vaccination. RESULTS: Among 517 participants included in analyses, 489 (95%) were vaccinated by September 2021, and no participants were vaccinated subsequently. Except for briefly at the beginning, when few had received a vaccine, and end, when only 28 participants remained unvaccinated, anxiety symptom trajectories were largely overlapping. Participants who were never vaccinated had higher anxiety symptoms by August 2022, but there were no other differences, and receiving a vaccination did not appear to change anxiety symptom trajectories meaningfully. CONCLUSION: Vaccination did not appear to influence changes in anxiety symptoms among vulnerable people with SSc during the COVID-19 pandemic. This may be due to people restricting their behavior when they were unvaccinated and returning to more normal social engagement once vaccinated to maintain a steady level of anxiety symptoms.

ABSTRACT

Fibroblasts are crucial components of the skin structure. They were traditionally believed to maintain the skin's structure by producing extracellular matrix and other elements. Recent research illuminated that fibroblasts can respond to external stimuli and exhibit diverse functions, such as the secretion of pro-inflammatory factors, adipogenesis, and antigen presentation, exhibiting remarkable heterogeneity and plasticity. This revelation positions fibroblasts as active contributors to the pathogenesis of skin diseases, challenging the traditional perspective that views fibroblasts solely as structural entities. Based on their diverse functions, fibroblasts can be categorized into six subtypes: pro-inflammatory fibroblasts, myofibroblasts, adipogenic fibroblasts, angiogenic fibroblasts, mesenchymal fibroblasts, and antigen-presenting fibroblasts. Cytokines, metabolism, and epigenetics regulate functional abnormalities in fibroblasts. The dynamic changes fibroblasts exhibit in different diseases and disease states warrant a comprehensive discussion. We focus on dermal fibroblasts' aberrant manifestations and pivotal roles in inflammatory and autoimmune skin diseases, including psoriasis, vitiligo, lupus erythematosus, scleroderma, and atopic dermatitis, and propose targeting aberrantly activated fibroblasts as a potential therapeutic strategy for inflammatory and autoimmune skin diseases.
