Abstract
OBJECTIVE To define concomitant risk factors, treatment, and outcomes for patients with nonnephrogenic calciphylaxis (NNC). PATIENTS AND METHODS A retrospective review of Massachusetts General Hospital (MGH) medical records (January 1, 2014, through February 29, 2016) and a systematic literature review of PubMed, Google Scholar, EMBASE, MEDLINE, and CENTRAL (August 1, 1970, through July 31, 2016) were performed. Demographic characteristics and concomitant features were summarized and compared between patients with different lesion characteristics. Outcomes (lesion improvement and mortality) and their predictors were analyzed. RESULTS Nine patients (median age, 72 years [interquartile range (IQR), 44-82 years]; 78% women; 89% white race) were identified through MGH records. The literature review identified 107 patients (median age, 60 years [IQR, 49-72 years]; 77% women; 86% white race). Vitamin K antagonism and obesity were the most common concomitant factors. In the literature review, lower age (P<.001) and higher body mass index (P=.03) were associated with the central location of lesions, whereas vitamin K antagonism was associated with the peripheral location (P=.009). In the MGH series, median survival was 24.0 months (95% CI, 7.8-36.0 months), and 33% (95% CI, 14%-60%) had lesion improvement by 6 months. In the literature review, median survival was 4.2 months (95% CI, 1.9-5.9 months), median time to lesion improvement was 5.9 months (95% CI, 3.9-8.9 months), and none of the treatments were associated with lesion improvement or survival. CONCLUSION This description of concomitant traits may augment an earlier recognition of NNC. Future research is needed to investigate NNC pathogenesis and treatments.

Abstract
Calciphylaxis, now better known as Calcific uraemic arteriolopathy (CUA), is an uncommon condition characterised by small vessel calcification and occlusion with resultant painful violaceous skin lesions that typically ulcerate to form non-healing gangrenous ulcers. The syndrome is usually found in patients with renal failure. In this report we describe a 61 year old lady who developed lower limb ulceration secondary to calciphylaxis and discuss the current treatment options for this serious condition.

Abstract
Vascular calcification is implicated in the pathogenesis of atherosclerosis, diabetes and chronic kidney disease. Human vascular smooth muscle cells (HSMCs) undergo mineralization in response to elevated levels of inorganic phosphate (Pi) in an active and well-regulated process. This process involves increased activity of alkaline phosphatase and increased expression of core binding factor α-1 (CBF-α1), a bone-specific transcription factor, with the subsequent induction of osteocalcin. It has been shown that heavy alcohol consumption is associated with greater calcification in coronary arteries. The goal of our study was to examine whether ethanol alters mineralization of HSMCs provoked by high Pi. Exposure of HSMCs to ethanol increased extracellular matrix calcification in a dose responsive manner, providing a significant additional calcium deposition at concentrations of ≥60 mmol/l. HSMC calcification was accompanied by further enhancement in alkaline phosphatase activity. Ethanol also provoked a significant increase in the synthesis of osteocalcin. Moreover, in cells challenged with ethanol the expression of CBF-α1, a transcription factor involved in the regulation of osteoblastic transformation of HSMCs, was elevated. The observed effects of ethanol were not due to alterations of phosphate uptake by HSMCs. We conclude that ethanol enhances Pi-mediated human vascular smooth muscle calcification and transition of these cells into osteoblast-like cells.

Abstract
PURPOSE OF REVIEW Calcific uraemic arteriolopathy (CUA) or calciphylaxis is a rare but important cause of morbidity and mortality in patients with chronic kidney disease. The prevalence of CUA is increasing in patients with renal failure, and the condition is also being recognized in nonuraemic patients. RECENT FINDINGS There has been increasing understanding of the molecular basis of vascular calcification, in particular on the important role of the uraemic microenvironment in the factors implicated in the differentiation of vascular smooth muscle cells into osteoblasts. New options for treatment of hyperphosphataemia and secondary hyperparathyroidism in patients with chronic kidney disease have become available in the last few years and these have begun to be used in patients with CUA. These include bisphosphonates, newer noncalcium/nonaluminium-containing phosphate binders and case reports of use of cinacalcet. Other treatments for CUA that are not targeted directly at calcium/phosphate homeostasis include hyperbaric oxygen and the antioxidant cation chelator sodium thiosulphate. SUMMARY Clinicians managing patients with CUA should consider a combination approach of treating deranged calcium/phosphate with newer therapeutic agents and promoting wound healing with other older modalities such as hyperbaric oxygen and sodium thiosulphate infusions. Randomized controlled trials for treatments in CUA are still lacking.

Abstract
Calciphylaxis is defined by the presence of calcium deposits within the wall of small and medium-sized vessels. It is classically considered a life-threatening disease in patients with end-stage renal disease under dialysis. Clinically, it is characterized by the presence of painful plaques surrounded by a reticulate purpura that progresses to nonhealing ulcers, predominately in the lower limbs. It is associated with elevated parathyroid hormone levels and a dysregulation of the calcium/phosphate metabolism. In the absence of renal disease, normal parathyroid hormone levels, and calcium/phosphorus product, a good prognosis and the observation of similar calcium deposits associated with different conditions or even an epiphenomenon in diseases with well-known diagnosis leads one to consider the term calciphylaxis controversial.

Abstract
BACKGROUND AND OBJECTIVES Calciphylaxis, or calcific uremic arteriolopathy, is a well-described entity in end-stage kidney disease and renal transplant patients; however, little systematic information is available on calciphylaxis from nonuremic causes. This systematic review was designed to characterize etiologies, clinical features, laboratory abnormalities, and prognosis of nonuremic calciphylaxis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A systematic review of literature for case reports and case series of nonuremic calciphylaxis was performed. Cases included met the operational definition of nonuremic calciphylaxis-histopathologic diagnosis of calciphylaxis in the absence of end-stage kidney disease, renal transplantation, or acute kidney injury requiring renal replacement therapy. RESULTS We found 36 cases (75% women, 63% Caucasian, aged 15 to 82 yr) of nonuremic calciphylaxis. Primary hyperparathyroidism, malignancy, alcoholic liver disease, and connective tissue disease were the most common reported causes. Preceding corticosteroid use was reported for 61% patients. Protein C and S deficiencies were seen in 11% of patients. Skin lesions were morphologically similar to calcific uremic arteriolopathy. Mortality rate was 52%, with sepsis being the leading cause of death. CONCLUSION Calciphylaxis should be considered while evaluating skin lesions in patients with predisposing conditions even in the absence of end-stage kidney disease and renal transplantation. Nonuremic calciphylaxis is reported most often in white women. Mineral abnormalities that are invoked as potential causes in calcific uremic arteriolopathy are often absent, suggesting that heterogeneous mechanisms may contribute to its pathogenesis. Nonuremic calciphylaxis is associated with high mortality, and there is no known effective treatment.

Abstract
Calciphylaxis is a rare condition with a high mortality involving mural calcification of small vessels and occurring primarily in patients with end-stage renal disease. Most cases are characterized by rapid progression of tender subcutaneous nodules or cutaneous plaques to epidermal necrosis, with death in the majority of cases occurring from sepsis. The condition is still poorly understood and the pathogenesis not known. We report a case of calciphylaxis following an unusually benign course. Our patient was a 63-year-old Chinese woman with end-stage renal failure undergoing peritoneal dialysis who presented with itchy pruriginous rashes on her limbs and trunk with subsequent development of eschars and ulceration. Biopsy confirmed the presence of calcification within vessel walls in the subcutis. She was managed conservatively and refused a parathyroidectomy. Surprisingly, her disease did not worsen but remained stable. She died from an acute myocardial infarction 5 months after presenting to our clinic.

Abstract
'Calciphylaxis', a calcification syndrome associated with ischaemic cutaneous necrosis, is acquired naturally in humans in disease states. It is a life and limb-threatening complication, usually observed in patients with renal disease and secondary hyperparathyroidism, but known to occur in the absence of renal or parathyroid disease. The reported mortality rate, which ranges from 60-80%, relates to wound infection, sepsis and organ failure. It is a small-vessel vasculopathy, which is estimated to occur in about 4% of haemodialysis patients. Clinically, violaceous, reticulate areas of cutaneous necrosis and eschar may be evident, particularly in the extremities. In addition to the clinical picture, a raised calcium phosphorous product, an elevated parathyroid hormone level, radiographic evidence of vessel and soft-tissue calcification and the finding of mural calcification affecting small arteries and arterioles on histopathology help to confirm the diagnosis of this entity which generally has a poor prognosis. A high index of suspicion and an active multidisciplinary management approach, with rigorous attention to wound care and prevention of sepsis, are vital in the management of these patients. In this overview, we discuss the pathophysiology, clinical features and associations, risk factors, diagnosis and management issues relating to calciphylaxis.

Abstract
Calciphylaxis is an uncommon disease characterized by calcification of dermal vessels that determines skin necrosis. Calciphylaxis has been almost exclusively reported in association with renal failure and altered phosphor-calcium metabolism. Only a few cases have been described in hyperparathyroidism, malignancies, and, recently, cirrhosis. We report a patient that developed calciphylaxis related to end-stage alcoholic cirrhosis, without any alteration in the phosphocalcic and parathyroid hormone metabolisms. Possible contributing factors were repeated albumin infusions and low levels of protein C and S.

Abstract
PURPOSE Calcific arteriolopathy (CA), also known as " Calciphylaxis " describes a phenomenon of necrosis, mainly cutaneous and sometimes systemic, due to the obliteration of the arteriole's lumen. Initially there are under-intimal calcium deposits, and then the thrombosis occurs leading to the necrosis. CA affects mainly the renal insufficient hemodialysed patient, but not exclusively. We present 4 cases which illustrate well the etiologic spectrum of CA: terminal renal insufficiency, neoplasia, primary hyperparathyroidism, proteinuria, vitamin K inhibitors. We describe the AC's epidemiology, its cutaneous and systemic clinical presentations, its treatment. We make the hypothesis that CA is a strong risk marker in matter of cardiac mortality and we discuss this point. CURRENT KNOWLEDGE AND KEY POINTS In this article we describe the numerous breakthroughs that have been made in matter of research about calcification over the past few years: inhibitors of calcium phosphate deposition, vitamin D and PTH1R, protein-calcium complexes, cell death, induction of bone formation. These data are analysed from a clinical point of view with practical purposes. We present CA not only as a cutaneous disease but as a systemic pathology. FUTURE PROSPECTS AND PROJECTS The CA epidemiology is an incentive to more diagnosis suspicion in front of organ infarct involving a patient likely to be concerned by CA. The scientific and therapeutic breakthroughs in matter of calcification enable a better prevention of the disease. Nevertheless it remains very difficult to cure when installed.

Abstract
BACKGROUND Calciphylaxis is a rare condition associated with chronic renal failure and entails a very poor prognosis. Pathogenesis is poorly understood but involves abnormalities in calcium and phosphorus metabolism that lead to vascular and extravascular calcification. Patients present with painful ulcerating plaques that progress to gangrenous wounds. Parathyroidectomy has been advanced as a life-saving intervention in these patients, but long-term results with wound healing and survival after parathyroidectomy are not well described. METHODS Between January 1987 and October 2003, 15 patients with biopsy-confirmed calciphylaxis were treated at the University of Wisconsin. Of these 15 patients, 9 were treated with medical therapy (bisphosphonates and phosphate binders), whereas 6 underwent parathyroidectomy. The medical records were reviewed, and patients or relatives were interviewed. Survival was determined by Kaplan-Meier analysis. RESULTS Four patients underwent subtotal parathyroidectomy, and two patients underwent total parathyroidectomy. All had reductions in the intact parathyroid hormone level (mean +/- SD, 25.2 +/- 4.5 pg/mL). Whereas all six patients treated with parathyroidectomy had partial/complete wound healing, only two of nine in the medical group had any improvements in the skin lesions (P = .006). With up to 80 months of follow-up, patients who underwent parathyroidectomy had a longer median survival compared with those who did not have surgery (39 vs. 3 months; P = .017). CONCLUSIONS On the basis of our long-term follow-up of this patient population, subtotal or total parathyroidectomy was associated with long-term survival and was more likely to promote healing if performed earlier in the course of disease. Therefore, patients with calciphylaxis from secondary hyperparathyroidism should be referred promptly for potential parathyroidectomy.

Abstract
Calciphylaxis is a rare condition of induced systemic hypersensitivity in which tissues respond to appropriate challenging agents with a sudden local calcification. It is characterized by acute calcium deposition in the medial layer of small and intermediate dermal vasculature that can lead to epidermal ischemia, ulceration, and necrosis. Calciphylaxis typically occurs in patients with end-stage renal disease who are undergoing dialysis and who have secondary hyperparathyroidism. Even in this population the incidence is less than 1%. The cause of calciphylaxis is unknown. However, it has been suggested that deficiencies of protein C and protein S may play a role in the pathophysiology of this disorder. Our patient is the fourth with cirrhosis to be reported to have developed calciphylaxis and adds further evidence that low levels of these anticoagulant factors may be an important etiologic factor for development of calciphylaxis. This report should alert the clinician that calciphylaxis occurs in patients with cirrhosis and should stimulate further research concerning the possible role of protein C and protein S deficiency in calciphylaxis.

Abstract
Calciphylaxis is a condition with a generally poor prognosis about which relatively little is known. Possible improvement in prognosis is noted if the diagnosis can be made early to avoid progression of soft tissue lesions and resulting complications. The mainstays of therapy are wound care and therapy aimed at controlling infection and the progression of disease. Parathyroidectomy seems to benefit some patients, but controversy remains as to the extent of overall patient benefit and scenarios for its appropriate use.
