Predictors of clinical features in early-onset severe systemic sclerosis: An analysis from a multicenter prospective observational Japanese cohort.

As the clinical course of systemic sclerosis (SSc) varies widely, prognostic indicators have been sought to predict the outcomes of individual patients. Racial differences in SSc render it necessary to validate prognostic indicators in different patient cohorts. In this study, we aimed to assess clinical and laboratory parameters in Japanese patients with early-stage SSc with diffuse cutaneous involvement and/or interstitial lung disease, and identify predictive factors for disease progression. We performed multivariate analyses of baseline clinical information to estimate symptoms 4 years later in Japanese patients with diffuse cutaneous SSc and/or SSc with interstitial lung disease. Patients were enrolled in the study within 5 years of disease onset at 10 Japanese SSc centers. Over 12 years, 115 patients followed up for 4 years were included in this study. The modified Rodnan skin score (mRSS) at 4 years correlated with the baseline mRSS and finger-to-palm distance, defined as the average length from the distal tip of the fourth finger to the distal palmar crease. The percentage predicted vital capacity (%VC) in year 4 positively and negatively correlated with initial %VC and the presence of anti-topoisomerase I antibodies, respectively. The Health Assessment Questionnaire Disability Index (HAQ-DI) at 4 years was positively and negatively associated with baseline HAQ-DI and %VC, respectively. The occurrence of digital ulcers within 4 years was associated with the initial presence of digital ulcers, finger-to-palm distance, and the presence of digital pitting scars and anti-topoisomerase I antibodies. This study identified several factors that may predict the progression of early-stage SSc in Japanese patients. Finger-to-palm distance may be a useful tool for predicting the progression of skin thickening and the development of digital ulcers in the early stages of severe SSc, but larger, long-term prospective studies are needed to confirm our findings.

Chronic trophic disorders in cocaine and heroin injectors: A multicenter retrospective observational descriptive study.

AIMS: To describe the demographic characteristics of heroin and cocaine injectors with chronic injection-related trophic disorders, as well as the clinical and progressive characteristics of these disorders. METHODS: A descriptive, observational, multicenter and retrospective study over the last 15 years. Patients were recruited via a call for cases and by consulting the health data warehouse of the university hospital center. RESULTS: The population comprised 39 injection drug users, of whom 79.5% were male, with a median age of 41 years. Subjects had numerous co-addictions and 70.5% were infected with hepatitis C virus. Trophic disorders were multiple in some cases: 43.5% of patients had lymphoedema, 87% had ulcers, and 56.5% had injection-related scars. Ulcers were multiple, large, and present for a median of 3 years. They were located on the upper limbs in 32.5% of cases. Ulcers constituted a source of complications in 64.5% of cases and these were infectious in 91% of cases (local, osteoarticular or systemic). During follow-up, 8 patients died and 21.5% of patients requiring ulcer care were lost to follow-up. CONCLUSIONS: This study showed a high rate of complications, particularly infections, of ulcers in injection drug users. Localization of these ulcers to the upper limbs, although rare in the general population, is relatively frequent in this population. Follow-up is difficult and cooperation between dermatologist and addictologist is essential to improve patient care.

Thymic stromal lymphopoietin and digital microvascular damage in systemic sclerosis patients: A pilot study.

BACKGROUND: Systemic sclerosis (SSc) is a complex autoimmune connective-tissue disease, characterised by vasculopathy and fibrosis of the skin and internal organs. Activation of microvascular endothelial cells (ECs) causes the intimal hyperplasia that characterises the vascular remodelling in SSc. The most frequent complication of SSc is the development of digital ulcers (DUs). Thymic stromal lymphopoietin (TSLP) may trigger fibrosis and sustain vascular damage. Aim of this study was to evaluate the correlation between serum level of TSLP and DUs. METHODS: 75 consecutive SSc patients were enrolled and serum TSLP levels were measured. The presence of history of DUs (HDU) was evaluated. Recurrent new DUs were defined as the presence of at least 3 episodes of DUs in a 12-months follow up period. The risk of developing new DUs was calculated by applying the capillaroscopic skin ulcer risk index (CSURI). RESULTS: The median value of TSLP was higher in patients with HDU than patients without HDU [181.67 pg/ml (IQR 144.67; 265.66) vs 154.67 pg/ml (IQR 110.67; 171.33), p < 0.01]. The median value of TSLP was higher in patients with an increased CSURI index than patients without an increased CSURI [188 pg/ml (IQR 171.33; 246.33) vs 159.33 pg/ml (IQR 128.67; 218), p < 0.01]. Kaplan-Meier curves demonstrated that free survival from new DUs was significantly (p < 0.01) lower in SSc patients with increased TSLP serum levels. CONCLUSION: TSLP might have a key role in digital microvascular damage of SSc patients.

Febrile ulceronecrotic Mucha-Habermann disease - a case and treatment review.

Febrile ulceronecrotic Mucha-Habermann disease is a rare and severe variant of pityriasis lichenoides, characterized by sudden onset of generalized ulceronecrotic papules that rapidly coalesce into ulcers associated with high fever. Systemic manifestations such as intravascular disseminated coagulation and pulmonary, cardiac, gastrointestinal, and central nervous system involvement are common. Treatment is based on oral corticosteroids, immunosuppressive drugs such as methotrexate, and general supportive treatment. The present case describes a stepwise approach to a patient with Mucha-Habermann disease with insufficient response to methotrexate.

Necrotic ulcers caused by Loxosceles rufescens bites: a report of seven patients and scanning electron microscopy of the spider.

Loxosceles rufescens is a spider that may bite humans. To describe the clinical manifestations and treatment of patients with bites caused by L. rufescens, and present scanning electron microscopy of the spider. Twelve patients are described, seven with a confirmed aetiological diagnosis as a sample of the spider was captured. In one case, scanning electron microscopy of the spider was performed. Seven patients presented with a single necrotic ulcer of varying morphology, with a purulent-necrotic bed, located on the neck (one patient), buttock (one patient), thigh (one patient), legs (three patients) and foot (one patient). All patients complained of burning and pain. No systemic symptoms were observed. All patients were treated with sodium hypochlorite solution packs, an equine catalase gel, and polyhexamethylene biguanide cream. Oral analgesics were added. In one patient, oral prednisone was prescribed. Two patients with bacterial superinfections were treated with i.v. piperacillin/tazobactam or i.m. ceftriaxone. All patients recovered within eight weeks, however, a scar developed in five of six patients. The sequence of cutaneous manifestations due to L. rufescens bites is typical. At first, erythema and oedema forms, followed by a vesicle, blister or pustule and, finally, an eschar and scar. Systemic symptoms and signs are rare. To consider this spider as an aetiological agent of necrotic ulcers, it is necessary to capture a sample of the spider, dead or alive, which should then be identified by an expert. Corticosteroids, antibiotics and analgesics are frequently used. Surgery is often necessary.

Portuguese Recommendations for the management of Raynaud's phenomenon and digital ulcers in systemic sclerosis and other connective tissue diseases.

OBJECTIVE: To develop evidence-based recommendations for the non-pharmacological and pharmacological management of Raynaud's phenomenon (RP) and digital ulcers (DUs) in patients with systemic sclerosis and other immune-mediated connective tissue diseases (CTDs). METHODS: A task force comprising 21 rheumatologists, two surgeons (vascular and plastic), two nurses, and one patient representative was established. Following a systematic literature review performed to inform the recommendations, statements were formulated and discussed during two meetings (one online and one in-person). Levels of evidence, grades of recommendation (GoR), and level of agreement (LoA) were determined. RESULTS: Five overarching principles and 13 recommendations were developed. GoR ranged from A to D. The mean ± standard difference (SD) LoA with the overarching principles and recommendations ranged from 7.8±2.1 to 9.8±0.4. Briefly, the management of RP and DUs in patients with CTDs should be coordinated by a multidisciplinary team and based on shared decisions with patients. Nifedipine should be used as first-line therapy for RP and/or DUs. Sildenafil, tadalafil, and/or iloprost IV are second-line options for severe and/or refractory patients with RP and/or DUs. Sildenafil, tadalafil and/or Iloprost IV, should be prescribed for healing and prevention (also including bosentan) of DUs. In patients with RP and/or DUs, non-pharmacological interventions might be considered as add-ons, but there is limited quality and quantity of scientific evidence supporting their use. CONCLUSIONS: These recommendations will inform rheumatologists, specialist nurses, other healthcare professionals, and patients about a comprehensive and personalized management of RP and DUs. A research agenda was developed to address unmet needs, particularly for non-pharmacologic interventions.

Treatment of Chronic Parastomal Ulceration with Silver Sulfadiazine and Hyaluronic Acid: Two Case Reports.

ABSTRACT: Skin complications in individuals with an ostomy are widely reported and can cause physical and emotional challenges in everyday life. Chronic parastomal skin complications can be difficult to heal and cause significant pain.Two patients presented to the stomal therapy clinic for treatment and were diagnosed with chronic parastomal skin ulceration. Following standard treatment of wound management, topical corticosteroid ointment, and appliance review, the ulcers either were not improving or had reoccurred. Treatment with a combination cream consisting of 0.2% hyaluronic acid and 1% silver sulfadiazine was initiated, and both patients demonstrated complete healing.Treatment of parastomal skin ulceration with dual-action cream 0.2% hyaluronic acid and 1% silver sulfadiazine was successful for these two patients, with a reduction in pain and purulent fluid noted throughout treatment, in addition to a reduced cost of treatment when compared with standard protocols.

2023 Brazilian Society of Rheumatology guidelines for the treatment of systemic sclerosis.

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.

A rare case of trigeminal trophic syndrome with periorbital cellulitis and full-thickness upper eyelid defect in an undiagnosed patient with human immunodeficiency virus: a case report.

BACKGROUND: Trigeminal trophic syndrome is a rare cranial and facial condition caused by damage to the central or peripheral branches of the trigeminal nerve. This syndrome consists of a triad of anesthesia, paresthesia, and crescent-shaped facial ulcer involving the ala nasi and sometimes extending to the upper lip. Although previous screening for human immunodeficiency virus in some patients with trigeminal trophic syndrome was negative, we present a unique case of trigeminal trophic syndrome who tested positive for human immunodeficiency virus with eye complications. CASE PRESENTATION: We present a rare case of trigeminal trophic syndrome in a 44-year-old Black African woman who tested positive for human immunodeficiency virus. She presented with a 6-week history of progressive, persistent, and painless left sided facial and scalp ulcerations that started as small skin erosion. Diagnosis of trigeminal trophic syndrome was made on clinical grounds based on the triad of anesthesia, paresthesia, and unilateral crescent-shaped ulcer in the trigeminal dermatome and her past medical history. The ulcer healed completely after counseling and pharmacological therapy, but she later developed left periorbital cellulitis and left upper eyelid full-thickness defect. CONCLUSION: This is by far the first documented case of trigeminal trophic syndrome with a positive human immunodeficiency virus test. Testing for human immunodeficiency virus in patients with trigeminal trophic syndrome is necessary as this can help improve clinical management and treatment outcomes. Seeking the services of specialists remotely in resource constraint settings is beneficial for managing complications associated with trigeminal trophic syndrome.

Long-Term Data on Efficacy and Safety of Selexipag for Digital Systemic Sclerosis Vasculopathy.

OBJECTIVE: Raynaud phenomenon (RP) and digital ulcers (DUs) are the main signs of digital vasculopathy in systemic sclerosis (SSc). Selexipag is an oral prostacyclin agonist approved for SSc-related pulmonary arterial hypertension. Following our previous preliminary short-course report, we herein present long-term data on selexipag safety and efficacy in the treatment of SSc digital vasculopathy. METHODS: Selexipag was administered to patients with SSc with severe digital vasculopathy refractory or with contraindication to all other vasoactive therapies. Each subject was assessed at baseline and after 3, 6, and 12 months. Clinical outcomes related to RP and DUs were evaluated along with modified Rodnan skin score of the fingers. Digital perfusion was assessed by laser speckle contrast analysis (LASCA). Nailfold videocapillaroscopy (NVC) was also performed. RESULTS: Eight patients with SSc (63% female, mean age 50.1 years) received selexipag. After 12 months of treatment, RP was reported to significantly decrease in the number of daily episodes and mean duration (P < 0.001 and P = 0.01, respectively). All patients achieved a complete healing of their DUs (P = 0.03) within 6 months. A progressive reduction of fingers skin score was observed (P = 0.03). No structural changes of capillaries were noted on NVC. Conversely, LASCA revealed an important increase in total digital perfusion (P = 0.004) despite seasonal variability. The safety profile was consistent with that reported in the literature. CONCLUSION: We observed a sustained efficacy of selexipag on SSc digital vasculopathy during 1 year of administration. Our promising results encourage the design of a new randomized controlled trial to evaluate the effect of selexipag on SSc digital vasculopathy.

Multimodality management of locoregionally extensive Marjolin ulcer: a case report and review of the literature.

BACKGROUND: Marjolin ulcer (MU) is an aggressive cutaneous malignancy that commonly occurs in those with a chronic wound such as post-burn scar. CASE REPORT: A 20-year-old male who sustained a flame burn over the scalp at 3 months of age developed a nonhealing ulcer over the burn scar 20 years later, which was treated with adequate surgical margins with adjuvant mold brachytherapy. Two months after completion of that treatment, he developed parotid nodal metastasis with positron emission tomography (PET)-positive bilateral cervical, supraclavicular, right suboccipital, and mesenteric lymph nodes that were treated with concurrent chemoradiation. One month later, the patient developed an ulcerative lesion involving the left parotid region with PET showing infiltration of the parotid gland, but with resolution of other previous sites of uptake. The patient was treated surgically with radical parotidectomy with elective neck dissection and reconstruction with locoregional flap. At 6-month follow-up, the patient developed extensive locoregional recurrence and distant metastasis and was started on oral metronomic therapy. The patient was alive with stable disease at 3-month follow-up after initiation of palliative chemotherapy. CONCLUSION: Despite timely multimodality therapy, MU may present with a hostile clinical course with a short disease-free interval and early recurrence.

Perianal Ulcers from Antihemorrhoidal Ointment: A Case Report and Literature Review.

ABSTRACT: Perianal ulcers (PAUs) related to antihemorrhoidal product use have been recently reported in the literature through a few case reports. However, other etiologies of PAU must be ruled out, including infectious disease, inflammatory disease, malignancy, pressure injuries, radiotherapy, and other topical drugs. In this report, the authors describe two cases of PAUs due to an antihemorrhoidal ointment. In case 1, a 68-year-old woman with a history of hemorrhoids presented with PAUs after using an antihemorrhoidal ointment for 2 months. The ulcers were assessed through a histopathologic study and treated with calcium alginate dressings, with complete re-epithelialization occurring after 2 months. In case 2, a 58-year-old woman with a history of hemorrhoids developed painful PAUs while using an antihemorrhoidal ointment for 2 months. No other probable cause was found, and the ulcers were treated by discontinuing the ointment. The ulcers showed marked improvement, and complete re-epithelialization occurred after 6 weeks without additional treatment.

Amyopathic Dermatomyositis Presenting with Digital Ulcerations: Case Report and Literature Review.

ABSTRACT: Clinically amyopathic dermatomyositis (CADM) is a rare subtype of dermatomyositis that presents with cutaneous features and no muscle involvement. This case report describes a 26-year-old woman with recurrent and multiple digital ulcerations coinciding with the start of winter each year. There was no evidence of myopathy, and antibody testing yielded negative results. A diagnosis of CADM was ultimately made based on clinicopathologic correlation. The patient's ulcers demonstrated excellent response to a combination therapy of hydroxychloroquine and potent topical and systemic steroids. Herein, the authors discuss the pathologic and immunologic characteristics of CADM.
