Scleroderma renal crisis

OBJECTIVES: Giant cell arteritis (GCA) in patients with systemic sclerosis (SSc) is rare, and optimal treatment strategies for this group of patients have not been defined. We aim to describe the first case series of GCA/SSc overlap. METHODS: A single-institution retrospective study was performed reviewing all patients that had diagnosis codes for both SSc and GCA between January 1, 1996, and December 31, 2020. Demographic characteristic, clinical presentation, diagnostic modality, treatment, and outcome data were abstracted...

Overlap syndromes are diseases that meet the criteria of two or more rheumatic diseases. In this case report, a woman in her 20s presented with a constellation of symptoms, including skin thickening, Raynaud's phenomenon, hypertension, absent pulse in both lower limbs with bilateral renal artery bruit. The antinuclear antibody profile revealed Scl-70 positivity. CT thorax identified early interstitial lung disease, and nailfold capillaroscopy showed severe capillary loss. CT angiogram features were suggestive of Takayasu arteritis...

Anti-human upstream-binding factor (anti-hUBF) antibodies have been reported predominantly in patients with connective tissue diseases (CTDs); these have also been reported in patients without CTDs such as hepatocellular carcinoma. Because of the low frequency of expression and few case reports, there is no consensus on the clinical significance of these antibodies. Thus, we aimed to examine the clinical features of patients with anti-hUBF antibodies and analyzed 1042 patients with clinically suspected CTDs...

Systemic sclerosis (SSc) is a multifaceted connective tissue disease whose aetiology remains largely unknown. Autoimmunity is thought to play a pivotal role in the development of the disease, but the direct pathogenic role of SSc-specific autoantibodies remains to be established. The recent discovery of functional antibodies targeting G-protein-coupled receptors (GPCRs), whose presence has been demonstrated in different autoimmune conditions, has shed some light on SSc pathogenesis. These antibodies bind to GPCRs expressed on immune and non-immune cells as their endogenous ligands, exerting either a stimulatory or inhibitory effect on corresponding intracellular pathways...

BACKGROUND: Nintedanib was approved for the treatment of scleroderma and scleroderma-related interstitial lung disease, as it decrease the forced expiratory volume. CASE PRESENTATION: A 48-year-old Asian female patient with systemic scleroderma 6 years ago developed breathlessness, nausea, heart palpation, and sudden severe occipital headache over the preceding week. She was receiving aspirin 81 mg/day and amlodipine 5 mg/day. Her diagnosis was diffuse scleroderma with pulmonary hypertension, interstitial lung involvement, and renal crisis...

Scleroderma renal crisis is a rare complication of systemic sclerosis characterized by a rapid decline in kidney function due to acute renal vascular injury. Recently, activating autoantibodies targeting the angiotensin II type 1 receptor and the endothelin-1 type A receptor have been implicated in the pathophysiology of scleroderma renal crisis by sensitizing the angiotensin II type 1 receptor and endothelin-1 type A receptor in renal resistance arteries to their natural ligands. Here, we describe a cohort of 10 patients with scleroderma renal crisis refractory to standard treatment, including blockade of the renin-angiotensin system...

BACKGROUND: The kidney biopsy is a routine procedure. Once an indication has been established, the benefit-risk balance may be considered. Sometimes, even with effective treatment, a severe complication may develop. CASE PRESENTATION: We present the case of a Caucasian 20-year-old young woman admitted to investigating and treating acute kidney injury. Renal involvement was characterized by kidney damage requiring hemodialysis treatment, positive immunologic testing, 0...

Systemic sclerosis, also referred to as scleroderma, is a chronic autoimmune disease that affects both internal organs and the skin. Systemic sclerosis predominantly affects female patients and can coexist with other disorders, including those affecting the thyroid gland. Common symptoms such as fatigue and weight changes can be attributed to either systemic sclerosis or thyroid disease. In this comprehensive review, an extensive analysis is conducted using research from 2002 to 2022, sourced from PubMed. The main focus of this exploration is to understand the intricate relationship between thyroid disorders and systemic sclerosis...

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...

BACKGROUND: Vascular phenotype is associated with a poor prognosis in systemic sclerosis (SSc). The identification of its risk factors could facilitate its early detection. OBJECTIVES: To explore risk factors for a vascular phenotype of SSc, among them a history of pre-eclampsia. METHODS: This observational multicentre case-control study enrolled adult women fulfilling European Alliance of Associations for Rheumatology 2013 diagnosis criteria for SSc and having a pregnancy history≥6 months before SSc diagnosis in 14 French hospital-based recruiting centres from July 2020 to July 2022...

A middle-aged woman presented with hypertensive emergency after corticosteroid treatment for Sjögren syndrome-associated multiple mononeuropathy with suspected systemic sclerosis. Hypertensive heart failure with hyperreninemia improved with antihypertensives, including aliskiren; however, she became hemodialysis-dependent. Clinical findings and biopsy-proven thrombotic microangiopathy indicated conditions resembling scleroderma renal crisis (SRC). Severe hypertension and heart failure with hyperreninemia occurred after stopping aliskiren for hypotension due to diverticular bleeding, which improved after the reintroduction of aliskiren...

Kidney involvement in systemic sclerosis occurs in about 20% of cases, with scleroderma renal crisis as a significant complication. However, cases of glomerular disease with massive proteinuria are rare. We present a unique case of systemic sclerosis with the development of nephrotic syndrome. The report provides clinical details and podocyte pathological findings. A 40-year-old male with prior skin sclerosis was diagnosed with systemic sclerosis. Treatment with oral prednisone led to gradual improvement, but a year later, he experienced a systemic sclerosis renal crisis...

OBJECTIVE: The renin-angiotensin-aldosterone system (RAAS) and glucocorticoids (GCs) are involved in vascular remodeling and fibrosis, but have not been extensively studied in systemic sclerosis (SSc). Our aim was to investigate the RAAS and GC hormones in SSc patients. METHODS: Serum levels of renin (dosage and activity), aldosterone and its precursors (DOC, B, 18-OH-DOC, 18-OH-B), and GCs (cortisol, cortisone, 11-deoxycortisol, 18-OH-F) were assessed in 122 SSc patients and 52 healthy controls...

BACKGROUND: Scleroderma renal crisis (SRC) is a critical kidney involvement of systemic sclerosis (SSc), often resulting in end-stage renal disease. Although the recurrence of SRC in the allograft has been reported, the development of de novo SRC after kidney transplantation has not been reported. Furthermore, normotensive SRC, which rarely occurs, makes prompt diagnosis more challenging. This fact should be recognized widely among nephrologists. CASE PRESENTATION: We report a 37-year-old Japanese man with overlapping SSc/systemic lupus erythematous syndrome who developed normotensive SRC in the transplanted kidney shortly after glucocorticoid escalation...

Autologous hematopoietic stem cell transplantation (aHSCT) represents an effective treatment option in patients with severe forms of systemic sclerosis (SSc) by resetting the immune system. Nevertheless, secondary autoimmune disorders and progressive disease after aHSCT might necessitate renewed immunosuppressive treatments. This is particularly challenging when organ dysfunction, i.e., end-stage kidney failure, is present. In this case report, we present the unique case of a 43-year-old female patient with rapidly progressive diffuse systemic sclerosis who underwent aHSCT despite end-stage renal failure as consequence of SSc-renal crisis...

BACKGROUND: Scleroderma renal crisis (SRC) is a devastating complication of diffuse cutaneous systemic sclerosis (dcSSc) that occurs in 5% to 20% of patients in this population. End-stage kidney disease develops in 25% to 40% of SRC, and mortality occurs in 50% at 5 years. Kidney transplantation (KT) is a viable option, but little data exist on outcomes. METHODS: We performed a retrospective study of all patients with dcSSc who underwent KT at Northwestern Hospital between 2000 and 2020...

Typical or atypical presentations of rare diseases may be confounded by co-morbidities in critically-ill patients. It is imperative to diagnose and treat appropriately, despite this difficulty. Scleroderma renal crisis mimics many other conditions, and can be potentially fatal if not caught early enough. Particularly, in critically-ill patients with multiple pathologies, it can be difficult to distinguish scleroderma renal crisis from other diseases, such as thrombotic thrombocytopenic purpura (TTP), hypertensive emergency, posterior reversible encephalopathy syndrome (PRES), or atypical hemolytic uremic syndrome (HUS)...

Systemic sclerosis (SSc) can lead to dyspnea and respiratory failure through multiple mechanisms, making a precise diagnosis particularly challenging, especially amid the current COVID-19 pandemic. In this report, we present a case involving a 26-year-old female who had previously undiagnosed SSc. She experienced acute respiratory failure necessitating orotracheal intubation. Following an extensive evaluation, the patient exhibited skin thickening, kidney failure, thrombocytopenia, microangiopathic anemia, and an antinuclear antibody with a nuclear fine speckled pattern at a titer of 1:320...

This case report can be considered a rare occurrence of scleroderma renal crisis (SRC) presenting with a severe clinical course and multiple organ failure. A patient diagnosed with systemic sclerosis four years earlier was admitted to the hospital because of severe malignant systolic-diastolic arterial hypertension and acute kidney injury (AKI). Exacerbating disease suggested thrombotic microangiopathy (TMA) and the PLASMIC (Platelet count; combined hemoLysis variable; absence of Active cancer; absence of Stem-cell or solid-organ transplant; MCV; INR; Creatinine) score was used in the differential diagnosis...
