BACKGROUND: Untreated calciphylaxis is a fatal disease of intra- and extravascular calcification, most commonly presenting in end-stage renal disease (ESRD) patients. While early identification is critical for timely treatment, early-stage clinical and histopathological descriptions have not, to our knowledge, been elucidated. As early clinical recognition is essential to prompt definitive histopathological diagnosis, this study describes a range of clinical and histopathological manifestations of early-stage calciphylaxis...

BACKGROUND: Calciphylaxis is a serious complication in patients with chronic kidney disease associated mineral and bone disorder. It can occur in conditions with low and high bone turnover. So far, there are no definite diagnostic and therapeutic guidelines which may prevent the devastating outcome in many calciphylaxis patients. We report a case which clearly illustrates that knowledge of the underlying bone disorder is essential for a directed treatment. Based on this experience we discuss a systematic diagnostic and therapeutic approach in patients with calciphylaxis...

Calciphylaxis causes ischemia in multiple organs and skin ulcers owing to progressive calcification in small and medial arteries. It has a poor prognosis and often occurs in patients with hyperparathyroidism associated with end-stage renal failure and those undergoing hemodialysis. Here, we present a case of calciphylaxis associated with a wide range of symptoms, including lower thigh skin ulcers, a rectovaginal fistula, and femoral neck fracture. The patient underwent multiple treatments. However, she eventually died of cardiac failure...

INTRODUCTION: Calcific uraemic arteriolopathy (CUA), also called calciphylaxis, is a rare but potentially fatal vascular disorder that almost exclusively affects patients with chronic renal failure. The objective of this study was to analyse various risk factors for developing CUA and its subsequent clinical course according to the treatment received. MATERIALS AND METHODS: A retrospective study that included patients diagnosed with CUA from December 1999 to December 2015...

Calciphylaxis is a highly fatal syndrome of small vessel calcification that results in skin ischemia and necrosis.[1] Affected patients present with extremely painful, violaceous skin lesions that progress to non-healing ulcers, and can be complicated by superimposed infections and sepsis.[2] The mortality rate from calciphylaxis is estimated at 60-80%.[2, 3] Sodium thiosulfate (STS), an increasingly popular treatment for calciphylaxis, is theorized to work through vasodilation, antioxidation, and calcium chelation...

PURPOSE OF REVIEW: Calciphylaxis remains a poorly understood vascular calcification disorder with predilection for patients with end-stage renal disease (ESRD). Recent data from large patient registries and databases have begun to provide information regarding incidence, risk factors, and outcomes in patients with calciphylaxis. RECENT FINDINGS: The most recent estimate places the incidence of calciphylaxis at 3.5 new cases/1000 patient-years among the patients with ESRD on chronic hemodialysis...

Calciphylaxis (CPX) is a rare calcifying thrombotic vasculopathy responsible for painful necrotic ulcers, with a high mortality rate, and its management is often difficult. Recently, intravenous infusions of sodium thiosulfate (STS) have shown efficacy. The aim of this study was to assess the efficacy of intralesional STS (IL STS) in four patients. Our aim was to assess the efficacy of IL STS in a prospective mono-centric open study that included four patients with a biopsy-proven cutaneous CPX. Four women (55-84 years old, mean age: 71·2 years) with a uremic (n = 1) or non-uremic CPX (n = 3) and primary hyperparathyroidism induced by teriparatide or after the initiation of oral anti-vitamin K were treated by IL STS (250 mg/ml)...

PURPOSE: To describe a patient presenting with suspected giant cell (temporal) arteritis (GCA) in whom subsequent temporal artery biopsy showed luminal narrowing by medial calcification, metaplastic ossification, and fibrointimal proliferation, consistent with calciphylaxis. METHODS: A 55-year-old man with end-stage renal disease presented with unilateral loss of vision and elevated erythrocyte sedimentation rate and was initially treated as though he had GCA; however, a subsequent temporal artery biopsy showed marked luminal narrowing by medial calcification, metaplastic ossification, and fibrointimal proliferation, consistent with calciphylaxis...

BACKGROUND: The current gold standard for diagnosis of calciphylaxis is a skin biopsy specimen demonstrating calcification of small-caliber arteries or arterioles. OBJECTIVE: The aim of this study is to compare diameters of calcified vessels seen in skin biopsy specimens and radiology images of patients with calciphylaxis. METHODS: We conducted a retrospective study of patients with known calciphylaxis from 2009 to 2016 at a community hospital who had both skin biopsy specimens and radiology images taken as part of their routine care...

BACKGROUND: Livedoid vasculopathy and calciphylaxis are rare skin disorders. Large cohorts of patients have been missing so far for detailed analysis. PATIENTS AND METHODS: Data from diagnosis-related groups (DRGs) of hospitalized cases of livedoid vasculopathy (ntotal = 1357) and calciphylaxis (ntotal = 699) were analysed for the years 2008-2013 concerning sex, age and frequency of diagnosis. To avoid deviations to non-relevant secondary diagnosis and due to changes in ICD-10 indices, we selected the two most recent available years 2013 and 2014 for evaluation of the accompanying diagnoses for both, livedoid vasculopathy (n = 519) and calciphylaxis (n = 324)...

Calciphylaxis is a rare devastating medical condition commonly associated with end-stage renal disease and characterized by extensive microvascular calcifications. We describe a case of calciphylaxis presenting on Tc-99m MDP bone scan imaging with asymmetric radiotracer uptake within the lower extremities corresponding to extensive soft tissue calcifications on Computed tomography. Familiarity with the classic clinical presentation and imaging features of this rare entity may help its early identification and treatment...

BACKGROUND: Calcific uraemic arteriolopathy (calciphylaxis) is an unusual and potentially fatal condition characterised by small-vessel calcification and ischaemic skin necrosis. It mainly affects patients with end-stage renal disease (ESRD) on haemodialysis, but may rarely occur in the absence of ESRD in conditions such as primary hyperparathyroidism, malignancy, alcoholic liver disease and connective tissue disease. METHODS: We reviewed the records of all patients diagnosed with calciphylaxis while on renal replacement therapy at Tygerberg Hospital, Cape Town, South Africa, between 1990 and 2014, to describe its presentation, course and final outcome...

OBJECTIVE: Chronic wounds are a major cause of morbidity and mortality. Approximately 20% to 23% of nonhealing wounds that are refractory to vascular intervention have other causes, including vasculitis, pyoderma gangrenosum, and other autoimmune diseases. The purpose of this article was to review the literature across medical and surgical specialties with regard to refractory chronic wounds associated with vasculitis and autoimmune diseases and to delineate clinical outcomes of these wounds in response to vascular and other interventions...

INTRODUCTION: Calciphylaxis/calcific uremic arteriolopathy affects mainly end-stage kidney disease patients but is also associated with malignant disorders such as myeloma, melanoma and breast cancer. Genetic risk factors of calciphylaxis have never been studied before. METHODS: We investigated 10 target genes using a tagging SNP approach: the genes encoding CD73/ ecto-5'-nucleotidase (purinergic pathway), Matrix Gla protein, Fetuin A, Bone Gla protein, VKORC1 (all related to intrinsic calcification inhibition), calcium-sensing receptor, FGF23, Klotho, vitamin D receptor, stanniocalcin 1 (all related to CKD-MBD)...

We report a case of nonuremic calcific arteriolopathy (NUCA) in an 82-year-old Caucasian woman from rural Australia. The patient had no history of kidney disease or dialysis. NUCA is rare disease suspected on cutaneous and clinical features and diagnosed by characteristic findings on skin biopsy and vasculature imaging. Calcification induced microvascular occlusion in the absence of renal failure may not be immediately apparent. Clinical suspicion and appropriate investigations are essential for making a diagnosis...

Importance: Classic calciphylaxis associated with renal failure is a life-threatening disease. Warfarin-associated calciphylaxis without renal injury has been described, but whether it is a subset of classic calciphylaxis or a different entity remains unknown. We describe 1 case of warfarin-associated calciphylaxis, present data from 2 others from our institution, and review all cases of warfarin-associated calciphylaxis available in the literature. Our review indicates that warfarin-associated calciphylaxis is clinically and pathophysiologically distinct from classic calciphylaxis...

Matrix Gla protein (MGP) is a potent inhibitor of vascular calcification. The ability of MGP to inhibit calcification requires the activity of a vitamin K-dependent enzyme, which mediates MGP carboxylation. We investigated how MGP carboxylation influences the risk of calciphylaxis in adult patients receiving dialysis and examined the effects of vitamin K deficiency on MGP carboxylation. Our study included 20 patients receiving hemodialysis with calciphylaxis (cases) and 20 patients receiving hemodialysis without calciphylaxis (controls) matched for age, sex, race, and warfarin use...
