A Black woman in her 40s with past medical history significant for obesity treated with Roux-en-Y bypass surgery and a history of Raynaud's phenomenon, presented with acute pulmonary edema secondary to severe malignant hypertension and critically accelerated acute kidney injury, with evidence of systemic microangiopathic hemolytic anemia in the setting of clinical suspicion of systemic sclerosis sine scleroderma. Renin-angiotensin system blockade (angiotensin-converting enzyme inhibitor) was immediately started at the maximum possible dose in the setting of scleroderma renal crisis. Despite better control of blood pressure and volume status, kidney function continued to rapidly decline, thus a decision was made to go ahead with a kidney biopsy on day 3 of admission, which revealed severe features of scleroderma renal crisis with active thrombotic microangiopathy. The multidisciplinary team elected to treat the patient with terminal complement blockade using eculizumab in addition to high dose lisinopril and blood pressure control. Her serum creatinine peaked at 9.3 mg/dL shortly after eculizumab initiation, but improved soon after, dropping to 2.8 mg/dL after completion of the final eculizumab dose and 1.8 mg/dL 3 years later.

Unusual radiographic progression of tumoral calcinosis along the anterior cruciate ligament in an adolescent male.
Proc (Bayl Univ Med Cent)

Texas A&M University, Temple, Texas, USA.
A 13-year-old boy was referred to orthopedic surgery for chronic intermittent pain and swelling of the left knee. Initial imaging was consistent with osteochondritis dissecans of the femoral condyle. Follow-up imaging demonstrated unexpected progression, with a mass extending into the notch, replacing the anterior cruciate ligament, and eroding the femoral and tibial condyles.

Objectives: Anticentromere antibodies (ACA) are typically found in limited cutaneous systemic sclerosis (lcSSc), whereas patients with anti-topoisomerase I antibodies (ATA) usually exhibit diffuse cutaneous involvement (dcSSc). We aimed to investigate the clinical phenotype and outcome of ACA-dcSSc.
Methods: A systematic literature review was conducted (January 1970 to April 2023) across MEDLINE, Scopus and OVID, to define whether SSc patients (population) within the ACA-dcSSc subset (exposure) had higher/lower risk for major organ involvement (interstitial lung disease-ILD, pulmonary hypertension-PH, primary myocardial involvement-PMI, scleroderma renal crisis-SRC) and mortality (outcomes) compared to ACA-lcSSc and ATA-dcSSc.
Article Synopsis
- - A study compared the outcomes of autologous hematopoietic stem cell transplantation (AHSCT) using unmodified peripheral blood stem cells (PBSC) with maintenance therapy (mycophenolate mofetil) versus a previously studied method that involved CD34+ selected PBSC in patients with diffuse systemic sclerosis (SSc).
- - In this trial involving 20 high-risk SSc patients, the 5-year overall survival (OS) was estimated at 85%, and event-free survival (EFS) was 75%, indicating promising results with this new approach.
- - The research highlighted a potential risk factor for poor outcomes in patients undergoing AHSCT: having a low estimated glomerular filtration rate (

Article Synopsis
- Systemic sclerosis (SSc) is a rare autoimmune disease classified into two groups based on skin involvement; this study investigates the role of autoantibody profiles in predicting organ damage and mortality compared to skin phenotype.
- Researchers analyzed data from 1,605 patients across seven French hospitals, focusing on autoantibodies and their correlation with various organ issues and death rates.
- Findings reveal that specific autoantibodies are strongly linked to serious complications like interstitial lung disease and renal crisis, while skin phenotype alone does not effectively predict patient outcomes.

Objective: Scleroderma renal crisis (SRC) is associated with high morbidity and mortality and there remain unmet needs regarding early identification and treatment. We aimed to assess risk factors for and the outcomes of SRC at a large Australian tertiary hospital.
Methods: Seventeen incident SRC cases were diagnosed between 2012 and 2022.
