Symptoms
Calciphylaxis is a type of vascular calcification generally seen in patients with kidney failure. The condition causes skin lesions and severe pain and usually has a high mortality rate. Typically, patients diagnosed with calciphylaxis live about six months. Dr.
Causes
With the help of a Young Investigator Grant from the National Kidney Foundation, Dr. Nigwekar is working to compile a biorepository of samples from patients with calciphylaxis in order to better understand the disease. The biorepository will help form the foundation of the first-ever clinical trial with calciphylaxis patients.
Complications
Most people who get calciphylaxis are going through end-stage kidney failure. However, there are some other known factors that can put you at risk for calciphylaxis: Women have a higher risk. Women are twice as likely to develop the disease. Being overweight or obese.
What is the life expectancy of calciphylaxis?
Secondly, the animals in experimental calciphylaxis were able to cast off the calcified skin molt and replace it with new dermis that did not have any features of calciphylaxis (Figure 3).

Are You at risk for calciphylaxis?
Can calciphylaxis be cast off?
Is calciphylaxis always fatal?
The risk of death within a year in non-uremic calciphylaxis cases is between 25% and 45%. With uremic calciphylaxis, the risk of death is between 45% and 80%. Ulcers and wounds: Lesions become ulcers and wounds in the late stages of calciphylaxis. The later a diagnosis happens, the worse the prognosis tends to be.
Can you get rid of calciphylaxis?
For sores to heal, some of the tissue damaged by calciphylaxis may need to be surgically removed (debridement). In some cases, tissue can be removed using other methods, such as wet dressings. Antibiotic treatment is part of treating and preventing wound infection.

There are a handful of cases in which calciphylaxis has been treated by successful kidney transplant, however, other cases have been reported in which calciphylaxis developed after kidney transplantation.
What is the survival rate for calciphylaxis?
The estimated 1-year survival rate for all patients with calciphylaxis has previously been reported as 45.8%5; and patients with ulceration fare worse, with an estimated 80% mortality. Patients in the present study had a high survival rate (75%) despite the fact that all patients had ulceration.
Does dialysis help calciphylaxis?
Calciphylaxis predominantly affects chronic kidney failure patients treated by dialysis. However, calciphylaxis is not limited to patients treated by dialysis and also occurs in patients with normal kidney function and in those with earlier stages of chronic kidney disease (referred to as non-uremic calciphylaxis).
Is calciphylaxis a death sentence?
Calciphylaxis is a rare complex medical syndrome that often has fatal clinical outcomes. Although most afflicted patients are described in end-stage renal disease (ESRD) or in post-transplantation, reports of nonrenal-related cases have been increasing. 1–3 The pathogenesis is not yet well understood.

Sodium thiosulfate (STS) is known as an antidote in cyanide intoxication and has recently been used for treating calciphylaxis.
How is calcification of the kidney treated?
Treatment involves ensuring adequate fluid intake and treating the underlying cause, if applicable, in order to prevent renal failure. Surgical therapy may be required in cases where there is significant stone formation in the renal tract, particularly if the stone causes obstruction and/or recurrent infections.
How do you break down calcium build up in your body?
Eating more green vegetables – Vitamin K helps to block off calcium from building up in your arteries. Reduce salt intake – Too much sodium in your diet can cause high blood pressure. High blood pressure weakens the walls of the arteries and makes it more likely for calcium to build up in this area.

Sodium thiosulfate (STS) is known as an antidote in cyanide intoxication and has recently been used for treating calciphylaxis.
Is calciphylaxis chronic?
Calcific uremic arteriolopathy (CUA), also known as calciphylaxis, is a rare complication of chronic kidney disease (CKD) where there is occlusion of microvasculature with mural calcification of the arterioles, causing severe ischemia and necrosis of the tissue [1].

Overview. Calciphylaxis (kal-sih-fuh-LAK-sis) is a serious, uncommon disease in which calcium accumulates in small blood vessels of the fat and skin tissues. Calciphylaxis causes blood clots, painful skin ulcers and may cause serious infections that can lead to death. People who have calciphylaxis usually have kidney failure ...
What are the symptoms of calciphylaxis?
Signs and symptoms of calciphylaxis include: Large purple net-like patterns on skin. Deep, very painful lumps that ulcerate creating open sores with black-brown crust that fails to heal — typically in skin areas with high fat content, such as the stomach and thigh, although they can occur anywhere.
What causes calcium to be deposited in the smallest parts of the arteries?
This causes calcium to be deposited in the smallest parts of the arteries (arterioles), which eventually leads to the formation of blood clots in the arterioles. Blood clots can cause fat tissues and skin to be deprived of oxygen and nourishment.
What is the imbalance of calcium, phosphorus and aluminum in the body?
Some medications, such as warfarin (Coumadin, Jantoven), calcium-binding agents or corticosteroids. An overproduction of parathyroid hormone ( PTH), which regulates the level of calcium and phosphorus in the body — a condition known as hyperparathyroidism.
What is the difference between experimental calciphylaxis and human calciphylaxis?
First and foremost, the animals in experimental calciphylaxis did not develop small artery or arteriolar calcifications although extensive soft tissue calcifications were present. Secondly, the animals in experimental calciphylaxis were able to cast off the calcified skin molt and replace it with new dermis that did not have any features of calciphylaxis (Figure 3). Thirdly, experimental calciphylaxis was prevented by administration of glucocorticosteroids, a fact that contradicts the available data in human calciphylaxis.9,12,37
What is calciphylaxis skin?
Calciphylaxis clinically presents with severe painful skin lesions (livedo reticularis, reticulate purpura, violaceous plaques, or indurated nodules) that demonstrate poor healing and are frequently complicated by blis tering and ulcerations with superimposed infections (Figure 1).7,16,17Ulcerated lesions commonly demonstrate black eschar. Although, skin manifestations dominate the clinical presentation, patients have been reported to have vascular calcifications in skeletal muscle, brain, lungs, intestines, eyes, and mesentery.18-24In this regard, calciphylaxis can be considered as a continuum of a systemic process leading to arterial calcification in many vascular beds.25Histologically, calciphylaxis is characterized by calcification, microthrombosis, and fibrointimal hyperplasia of small dermal and subcutaneous arteries and arterioles leading to ischemia and intense septal panniculitis (Figure 2).26-28Calcification most commonly involves the medial layer of small arteries and arterioles; however, involvement of the intimal layer and the interstitium of subcutaneous adipose tissue has been reported.17Calcification is considered to be an early and essential process in calciphylaxis plaque development and it is hypothesized that the vascular calcification leads to vascular endothelial dysfunction and injury.29-31Despite the well characterized clinical and histological descriptions of calciphylaxis, its exact pathogenesis remains unclear and there is limited data regarding the diagnostic and therapeutic approaches for this devastating condition.
Is calciphylaxis a hypersensitivity reaction?
The differences between experimental calciphylaxis and human calciphylaxis, as well as a widely accepted recognition that calciphylaxis is not a hypersensitivity reaction, has led some authors to propose descriptive terms such as calcific uremic arteriolopathy for human calciphylaxis.17,38,39Although descriptive terms incorporate pathological implications in a truer sense than calciphylaxis, it is important to take into account the ubiquitous use of calciphylaxis term in the medical community. Thus, our preference is to use the term calciphylaxis when referring to calciphylaxis patients on dialysis and non-uremic calciphylaxis to refer to patients with normal kidney function and those with earlier stages of CKD.9
Is calciphylaxis a rare disease?
Calciphylaxis is a rare but devastating condition that has continued to challenge the medical community since its early descriptions in the scientific literature many decades ago. It is predominantly seen in chronic kidney failure patients treated with dialysis (uremic calciphylaxis) but is also described in patients with earlier stages of chronic kidney disease and with normal renal function. In this In Practicefeature, we review the available medical literature regarding risk factors, diagnosis, and treatment of both uremic and non-uremic calciphylaxis. High quality evidence for the evaluation and management of calciphylaxis is lacking at this time due to its rare incidence, poorly understood pathogenesis, and the relative paucity of collaborative research efforts. We hereby provide a summary of recommendations developed by the Massachusetts General Hospital's Multi-disciplinary Calciphylaxis Team for calciphylaxis patients.
Is calciphylaxis more common in whites than non whites?
Calciphylaxis is most commonly reported in patients in the 5thdecade of life; however it has also been described in patients significantly younger including children.44,45Calciphylaxis is more commonly seen in women compared to men with a 2:1 female predominance.12,15,46Calciphylaxis in our experience and as reported in the literature is also more common in whites compared to non-whites.12,15,41,46The biological explanation for these observations is unclear.
Can hypercoagulation cause calciphylaxis?
Hypercoagulable conditions may predispose patients to calciphylaxis. There are case reports of calciphylaxis in patients with both hereditary and acquired thrombophilic conditions such as protein C and protein S deficiency, antithrombin III deficiency, cryofibrinogenemia, and anti-phospholipid antibody syndrome.50-53However, arguments against the potential causative role of hypercoagulable conditions have also been made. In a case control study of 49 uremic calciphylaxis patients and 98 control patients on dialysis, no significant difference between cases and controls for protein C activity, protein S antigen, or antithrombin III activity were noted.12Thrombi formation in venules that are frequently noted in patients with thrombophilic conditions are not seen in calciphylaxis patients.54Despite these arguments, evaluation for thrombophilic conditions in calciphylaxis patients should be considered since it has important treatment implications.
Is dysregulated calcium phosphorous metabolism a risk factor for calciphylaxis?
In our opinion, although the role of dysregulated calcium- phosphorous metabolism as a risk factor for calciphylaxis cannot be overlooked and requires further investigation in larger observation studies, it is not the sole risk factor for calciphylaxis.
